[0001] The present application relates to the technical field of electrical cleaning devices
for household use, and in particular, to a cleaning device.
[0002] As technology keeps developing and people's quality of life improves, cleaning devices
(such as vacuum cleaners and floor scrubbers) appear more and more in people's life.
A floor scrubber can scrub a floor while sucking up dirty water produced after the
scrubbing so as to keep the floor clean and dry.
[0003] In relevant art, a cleaning device comprises a device body and a handheld structure
removably connected to the device body. The handheld structure is used for providing
a suction force and can be used separately after being removed. The device body has
a loading slot used for loading the handheld structure, and the handheld structure
has a connecting end inserted in the loading slot so as to connect the handheld structure
to the device body.
[0004] However, after the existing handheld structure is connected to the device body, other
parts of the handheld structure are clearly exposed, and appear abrupt relative to
the device body, making the cleaning device complex in structure and poor in aesthetics.
[0005] In view of this, the present application provides a cleaning device that solves the
following problem: after an existing handheld structure is connected to a device body,
the handheld structure appears abrupt relative to the device body, making the cleaning
device complex in structure and poor in aesthetics.
[0006] The present application provides a cleaning device comprising a device body and a
handheld structure comprising a handheld body and an operating handle arranged on
the handheld body, wherein a side face of the device body is provided with a positioning
groove, and a supporting groove in communication with the positioning groove is provided
in the device body, and wherein the handheld body has an inserting end opposite to
the operating handle and inserted in the supporting groove, the supporting groove
envelops the inserting end, and a part of a side face of the handheld body and at
least a part of the operating handle are located in the positioning groove.
[0007] With the cleaning device provided by the present application, when the handheld structure
is inserted in the device body, the inserting end of the handheld body is completely
enveloped by the supporting groove of the device body, a part of a side face of the
handheld body is located in the positioning groove, and at least a part of the operating
handle is also located in the positioning groove. Thus, the supporting groove can
guide the insertion of the inserting end and protect the connection between the inserting
end and the device body. The partial structure of the handheld structure exposed outside
the positioning groove and the supporting groove can smoothly transition to an outer
surface of the supporting groove and an outer surface of the positioning groove, enabling
the handheld structure to be stably mounted in the device body in a hidden way, so
that the cleaning device has a smooth overall styling, a compact structure, and improved
aesthetics.
[0008] In a possible mode of realization, in the cleaning device provided by the present
application, the device body has a handheld part tilting towards the positioning groove.
[0009] Thus, by tilting the handheld part of the device body towards the positioning groove,
the handheld part and the handheld structure can be located at the same side of the
device body, so as to facilitate a user performing operations of mounting, removing,
and holding the handheld structure from the same side of the handheld part during
use, which further facilitates use of the cleaning device and improves user experience.
[0010] In a possible mode of realization, the cleaning device provided by the present application
further comprises a locking assembly comprising a pressing element and a locking element,
the pressing element being inserted in the device body having inside a mounting chamber
in communication with the positioning groove, the locking element being partially
located in the mounting chamber and partially located outside the mounting chamber
and snap-fit with the operating handle; the pressing element is configured to, when
being pressed, drive the locking element to move away from the operating handle so
as to disengage the locking element from being snap-fit with the operating handle.
[0011] Thus, by providing the locking assembly, under the effect of the snap-fit between
the locking element and the operating handle, combined with the insertion connection
between the inserting end and the supporting groove, the handheld structure and the
device body are reliably fixed together; when the handheld structure needs to be removed,
by applying a pressing force on the pressing element, the pressing element can drive
the locking element to disengage from being snap-fit with the operating handle, which
facilitates improving user experience and the efficiency in removing the handheld
structure.
[0012] In a possible mode of realization, the cleaning device provided by the present application
further comprises at least one elastic assembly located in the device body and partially
protruding into the positioning groove so as to abut against the operating handle;
the elastic assembly is configured to, when the operating handle disengages from being
snap-fit with the device body, drive the part of the operating handle in the positioning
groove to disengage from the positioning groove.
[0013] Thus, when removing the handheld structure, by disengaging the operating handle from
being snap-fit from the device body, the elastic assembly will drive the part of the
operating handle in contact with it to shift from a prior position so as to disengage
from the positioning groove, thus further facilitating holding of the operating handle
fully by a user, allowing it to be removed from the positioning groove easily, and
helping improve the efficiency in removing the handheld structure.
[0014] In a possible mode of realization, in the cleaning device provided by the present
application, an end face of the inserting end has a first electrical connector, and
a bottom of the supporting groove has a second electrical connector, the first electrical
connector being configured to, when the inserting end is inserted in the supporting
groove, be electrically connected to the second electrical connector.
[0015] Thus, when the inserting end is inserted in the supporting groove, an electrical
connection between the handheld structure and the device body can be realized by means
of the first electrical connector and the second electrical connector, so as to facilitate
electrical control of the handheld structure's operating state by the device body
when the handheld structure is inserted in the device body, so that the cleaning device
is more flexible and convenient to use.
[0016] In a possible mode of realization, in the cleaning device provided by the present
application, an end face of the inserting end has at least one first positioning element,
and a bottom of the supporting groove has at least one second positioning element,
the first positioning element being configured to, when the inserting end is inserted
in the supporting groove, be inserted to the second positioning element.
[0017] Thus, stability of the relative position and relative orientation between the inserting
end and the supporting groove can be ensured by the insertion connection between the
first positioning element and the second positioning element when the inserting end
and the supporting groove are connected by insertion with each other, improving accuracy
in mounting the handheld structure.
[0018] In a possible mode of realization, in the cleaning device provided by the present
application, among the first positioning element and the second positioning element,
one is a positioning slot, and the other is a positioning block that matches the positioning
slot.
[0019] Thus, by providing a positioning slot and a positioning block that matches the positioning
slot to form respectively the first positioning element and the second positioning
element, the structure of the first positioning element and the second positioning
element can be rendered simple and compact in structure, and positioning by insertion
connection can be rendered more efficient.
[0020] In a possible mode of realization, in the cleaning device provided by the present
application, there is an air passage in the handheld body, two ends of which form
respectively an air inlet located in the center of an end face of the inserting end,
and an air outlet located in a side face of the inserting end;
the device body has an air admission passage and an air discharge passage, an air
outlet of the air admission passage being located in the center of the supporting
groove and correspondingly in communication with the air inlet, an air inlet of the
air discharge passage being located in a side wall of the supporting groove and correspondingly
in communication with the air outlet.
[0021] Thus, when the device body and the handheld structure are used in combination, air
enters the handheld structure via the air inlet from the device body's air admission
passage, passes through the air passage, flows out of the air outlet, and then enters
the air discharge passage of the device body, and finally, is blown out of the air
discharge passage. As the air outlet is located in a side face of the handheld structure,
the air inlet and the air outlet of the handheld structure are not located at the
same end. With the air discharge passage being correspondingly in communication with
the air outlet, the air discharge passage need not be arranged at an opposite side
of the end of the handheld structure that has the air inlet. Thus, not too much inner
space of the device body is occupied, which facilitates the design and mounting of
other structures of the body.
[0022] In a possible mode of realization, the cleaning device provided by the present application
further comprises a first sealing element arranged between the air admission passage
and the air inlet, a second sealing element arranged between a side wall of the supporting
groove and a side face of the inserting end, and a connector;
the first sealing element and the second sealing element are connected by means of
the connector, the first sealing element and the connector are located in the same
plane, and the first sealing element, the second sealing element, and the connector
are formed integrally.
[0023] Thus, sealing between the air admission passage and the air inlet is improved by
means of the first sealing element, and sealing between the side wall of the supporting
groove and the side face of the inserting end is improved by the second sealing element.
Finally, by connecting the first sealing element and the second sealing element by
means of the connector, with the first sealing element, the second sealing element,
and the connector formed integrally, mounting and manufacturing of the first sealing
element, the second sealing element, and the connector are facilitated.
[0024] In a possible mode of realization, in the cleaning device provided by the present
application, the handheld body comprises a housing, a support, and a driving element
used for providing a suction force;
the support is partially inserted into the housing and provided inside with a chamber
in which the driving element is arranged, at least part of the support and the housing
adjacent to the support forming the inserting end.
[0025] Thus, on one hand, the support provides a mounting position for the driving element,
and on the other hand, part of the support and the housing adjacent to the support
form the inserting end, putting it to multiple uses, which helps reduce costs while
causing the overall structure to have a high stability.
[0026] In a possible mode of realization, in the cleaning device provided by the present
application, a part of the chamber forms the air passage, an end face of the support
facing the device body forms the end face of the inserting end, the air inlet corresponds
to a suction opening of the driving element, and the air outlet is located in a side
face of the support.
[0027] Thus, by forming the chamber mounted with the driving element and serving as the
air passage by means of the support, and with the support being processed to form
the air inlet and the air outlet, and the air outlet being located in a side face,
the overall structure is simple and compact, resulting in a high space utilization
rate.
[0028] In a possible mode of realization, in the cleaning device provided by the present
application, a side face of the support has a slot, an opening of the slot facing
a side wall of the supporting groove and forming the air outlet, the slot having a
first side wall and a second side wall that are opposite to each other, the first
side wall facing the handheld body; the second side wall is provided with at least
one through hole that puts the air passage and the slot in communication.
[0029] Thus, air is blown out of the air outlet via the through hole from the air passage.
With the opening of the slot facing the side wall of the supporting groove, by making
a slot in the side face of the support to form the air outlet, the structure is further
rendered compact, and full use is made of space.
[0030] In a possible mode of realization, in the cleaning device provided by the present
application, the first side wall is provided with a notch in communication with an
end face of the support facing the device body, so as to cause the opening to have
an inclined form.
[0031] Thus, by causing the opening to have an inclined form by means of the notch, the
direction of air blown out of the air outlet is axially inclined outwards relative
to the handheld body, which reduces wind resistance while at the same time fully making
use of the structure's space, and is equivalent to blowing towards the air discharge
passage at an angle.
[0032] In a possible mode of realization, the cleaning device provided by the present application
further comprises an outer connection structure configured to, when the handheld structure
detaches from the device body, be connected to the handheld structure and form, together
with the handheld structure, a cleaning executing device.
[0033] Thus, by providing the outer connection structure that can be connected to the separate
handheld structure to form a cleaning executing device, the functions of the handheld
structure can be completed when it is used separately, which increases the utilization
scenarios of the handheld structure and improves the handheld structure's functionality
and applicability so as to improve user experience when separately using the handheld
structure.
[0034] In a possible mode of realization, in the cleaning device provided by the present
application, the outer connection structure is a dust cup structure.
[0035] Thus, by providing a dust cup structure as the outer connection structure, the dust
cup structure can be used to receive dust and dirt sucked in by the handheld structure,
which improves the handheld structure's cleaning efficiency, renders it convenient
and practical, and improves a user's utilization experience.

listed or inherent to such process, method, product, or device.
[0044] In relevant art, a cleaning device comprises a device body and a handheld structure
removably connected to the device body. The handheld structure is used for providing
a suction force and can be used separately after being removed.
[0045] The device body has a mounting part, an upper part of which is provided with a handheld
part for being held, and a lower part of which is provided with a cleaning element,
such as a roller brush or scrubber disc, forming a floor scrubber part. Between the
handheld part and the floor scrubber part, the mounting part is further removably
mounted with a dust cup assembly, a water tank assembly, etc. in addition to a handheld
structure.
[0046] To realize the connection between the handheld structure and the device body, a side
of the device body is provided with a loading slot used for loading the handheld structure.
The loading slot is generally adapted to the structure and size of a part of the handheld
structure. The handheld structure has a connecting end inserted in the loading slot
so as to connect the handheld structure to the device body.
[0047] However, after the existing handheld structure is connected to the device body, other
parts of the handheld structure that are not adapted to the structure and size of
the loading slot are clearly exposed and appear abrupt relative to the device body's
overall configuration, easily making the cleaning device have a complex overall structure
and a low shape smoothness, resulting in poor aesthetics of the cleaning device.
[0048] In view of the above-described problems, the present application provides a cleaning
device comprising a device body and a handheld structure. When the handheld structure
is inserted in the device body, an inserting end of the handheld body is completely
enveloped by a supporting groove of the device body, a part of a side face of the
handheld body is located in a positioning groove, and at least a part of the operating
handle is also located in the positioning groove. Thus, the supporting groove can
guide the insertion of the inserting end and protect a part of the inserting end connected
to the device body. The partial structure of the handheld structure exposed outside
the positioning groove and the supporting groove can smoothly transition to an outer
surface of the supporting groove and an outer surface of the positioning groove, enabling
the handheld structure to be stably mounted in the device body in a hidden way, so
that the cleaning device has a smooth overall configuration, a compact structure,
and improved aesthetics.
[0049] Specific modes of realization of the cleaning device provided by embodiments of the
present application are described in detail below in conjunction with the accompanying
drawings.
[0050] It should be noted that Figs. 1 to 11 show schematically simplified schematic views
of various parts of a cleaning device. The specific structure of other parts of the
cleaning device is not limited to what is shown in Figs. 1 to 11 by way of example.
[0051] In reference to Figs. 1 to 4 and Fig. 6, a cleaning device provided by the present
application comprises a device body 100 and a handheld structure 200. The handheld
structure 200 comprises a handheld body 210 and an operating handle 220 arranged on
the handheld body 210. A side face of the device body 100 is provided with a positioning
groove 110. There is a supporting groove 120 in communication with the positioning
groove 110 in the device body 100. The handheld body 210 has an inserting end 211
opposite to the operating handle 220. The inserting end 211 is inserted in the supporting
groove 120, and the supporting groove 120 envelopes the inserting end 211. A part
of a side face of the handheld body 210 and at least a part of the operating handle
220 are located in the positioning groove 110.
[0052] It can be understood that, in order to render the handheld structure 200 more convenient
for a user to hold when being used separately from the device body 100, the operating
handle 220 is arranged on the handheld body 210 of the handheld structure 200. The
operating handle 200 is arranged at only one end of the handheld body 210 with its
extension direction consistent with that of the handheld body 210, its projection
towards the handheld body 210 being within the handheld body 210, an end of the handheld
structure 200 opposite the operating handle 220 being the inserting end 211. Thus,
various parts of the handheld structure 200 can be arranged in the same direction,
resulting in an overall styling that is smooth, aesthetic, simple, and compact. In
addition, when the handheld structure 200 is connected to the device body 100, mounting
of the handheld structure 200 in the length direction of the device body 100 is facilitated,
which reduces radial space of the device body 100 occupied by the handheld structure
200 so that the cleaning device is more elongated as a whole, improving the cleaning
device's aesthetics.
[0053] In addition, the device body 100 can comprise a first mounting part 170 and a handheld
part 130 removably connected to the first mounting part 170. In this embodiment, the
handheld part 130 is configured to be held by a user to facilitate control of the
device body 100's position. By way of example, partial structures of the handheld
part 130 and the first mounting part 170 ca be configured together as groove-shaped
structures, forming the positioning groove 110 and the supporting groove 120 that
match the handheld structure 200. The positioning groove 110 is arranged at a side
face of the device body 100 and comprises a receiving section 111 and an abutting
section 112 in communication with each other. The abutting section 112 is located
above the receiving section 111. When the operating handle 220 and part of the handheld
body 210 are arranged in the positioning groove 110, the receiving section 111 and
the abutting section 112 support the handheld structure 200 together, which helps
improve the stability of the handheld structure 200 and thus can ensure the structural
stability of the cleaning device. In addition, by providing the supporting groove
120 in communication with the positioning groove 110, when mounting the handheld structure
200, the inserting end 211 can be inserted into the supporting groove 120 and enveloped
by the supporting groove 120 so as to limit the inserting end 211's movement. Thus,
a mounting space that opens sideways can be formed by the positioning groove 110 and
the supporting groove 120, which facilitates mounting and removal of the handheld
structure 200 from one side of the device body 100.
[0054] As the operating handle 220 is located at one end of the handheld body 210, when
the handheld structure 200 is inserted into the mounting space formed by the positioning
groove 110 and the supporting groove 120, the mounting space can partially envelope
the handheld structure 200 to hide it, resulting in a smooth and sleek exterior styling.
In addition, as the handheld structure 200 itself does not have structural parts that
must protrude prominently from the mounting space, the partial structure of the handheld
structure 200 located outside the mounting space can be configured to transition smoothly
to the exterior structure of the positioning groove 110 and the supporting groove
120, so as to render the overall styling of the cleaning device more smooth and aesthetic.
[0055] Thus, when the handheld structure 200 is inserted in the device body 100, the inserting
end 211 of the handheld body 210 is completely enveloped by the supporting groove
120 of the device body 100, a part of a side face of the handheld body 210 is located
in the positioning groove 110, and at least a part of the operating handle 220 is
also located in the positioning groove 110. The partial structure of the handheld
structure 200 exposed outside the positioning groove 110 and the supporting groove
120 can smoothly transition to an outer surface of the supporting groove 120 and an
outer surface of the positioning groove 110, enabling the handheld structure 200 to
be stably mounted in the device body 100 in a hidden way, so that the cleaning device
has a smooth overall styling, a compact structure, and improved aesthetics.
[0056] With the above-described arrangement, a cleaning tool such as a brush can be further
provided on the first mounting part 170. Under the effect of the suction force provided
by the handheld structure 200, the brush is made to enter into contact with a surface
to be cleaned, so that the cleaning device can be used as a dust removal device capable
of removing dust from a surface to be cleaned such as a floor.
[0057] Even further, a dirty water tank and a clean water tank can be arranged in the first
mounting part 170, wherein the clean water tank is configured for distributing water
to a cleaning tool such as a brush to clean a surface to be cleaned, so that the cleaning
device is used as a floor scrubber and performs cleaning while removing dust from
a floor.
[0058] In some embodiments, in reference to Figs. 1 to 3, the device body 100 has a handheld
part 130 tilting towards the positioning groove 110.
[0059] It can be easily understood that by tilting the handheld part 130 towards the positioning
groove 110, the position of a user when using the cleaning device is always at the
side towards which the handheld part 130 tilts. Specifically, when using the cleaning
device, the handheld structure 200 and the user can both be located at the same side
of the device body 100, so as to facilitate a user's performing operations of mounting,
removing, and holding the handheld structure 200 from the same side of the handheld
part 130 when using the cleaning device, without the need to repeatedly adjusting
his or her position, which further facilitates use of the cleaning device and improvement
of user experience.
[0060] In some embodiments, in reference to Figs. 1 to 3 and Figs. 9 and 10, the cleaning
device further comprises a locking assembly 300 comprising a pressing element 310
and a locking element 320. The pressing element 310 is inserted in the device body
100. There is a mounting chamber 140 in communication with the positioning groove
110 in the device body 100. The locking element 320 is located in the mounting chamber
140. The locking element 320 is partially located outside the mounting chamber 140
and snap-fit with the operating handle 220. The pressing element 310 is configured
to, when being pressed, drive the locking element 320 to move away from the operating
handle 220 so as to disengage the locking element 320 from being snap-fit with the
operating handle 220.
[0061] It can be understood that, the positioning groove 110 is located at a side face of
the device body 100, and the mounting chamber 140 is located above the positioning
groove 110 so that the mounting chamber 140 is close to the handheld part 130, facilitating
operation by a user. Thus, the handheld part 130 can be provided with a first mounting
hole 141 and a second mounting hole 142 in communication with the mounting chamber
140. The pressing element 310 is inserted in the handheld part 130 via the first mounting
hole 141, and the locking element 320 is placed in the mounting chamber 140 at a side
corresponding to the operating handle 220. In this embodiment, to ensure that the
pressing element 310's movement is guided stably, a guiding part 143 can be provided
in the mounting chamber 140. The guiding part 143 is arranged to surround the periphery
of the first mounting hole 141. The pressing element 310 is slidably connected to
the guiding part 143.
[0062] In order to allow the operating handle 220 to be snap-fit with the positioning groove
110 stably, the operating handle 220 is provided with a snap-fit slot 221, and the
locking element 320 has a snap-fit tab 321 matching the snap-fit slot 221. By snap-fitting
the snap-fit tab 321 into the snap-fit slot 221, movement of the operating handle
220 away from the positioning groove 110 can be limited. In a normal state, the snap-fit
tab 321 of the locking element 320 will partially extend into the positioning groove
110 via the second mounting hole 142 and be snap-fit with the operating handle 220.
Thus, under the effect of the snap-fit between the locking element 320 and the operating
handle 220, in combination with the insertion connection between the inserting end
211 and the supporting groove 120, the handheld structure 200 and the device body
100 are fixed together reliably, which increases the reliability of the connection
between the handheld structure 200 and the device body 100 and improves user experience.
[0063] Specifically, regarding the transmission structure between the pressing element 310
and the locking element 320, the pressing element 310 can be provided with an insertion
block 311, and a face of the locking element 320 facing the insertion block 311 can
be provided with an insertion slot 322. There is a first slope 32221 in the insertion
slot 322. An end face of the insertion block 311 facing the insertion slot 322 has
a second slope 3111 that matches the first slope 3221. The first slope 3221 is slidably
connected to the second slope 3111.
[0064] Further, the locking assembly 300 further comprises a reset element 330 located in
the mounting chamber 140. Specifically, the reset element 330 abuts between the locking
element 320 and an inner wall of the mounting chamber 140 and maintains an extended
state.
[0065] Thus, when the pressing element 310 is pressed, it moves towards the receiving chamber
via the first mounting hole 141, and under the interaction of the first slope 3221
of the insertion slot 322 and the second slope 3111 of the insertion block 311, drives
the locking element 320 to move away from the positioning groove 110 and return into
the receiving chamber, so as to disengage from being snap-fit with the operating handle
220, while at the same time compressing the reset element 330 so that the reset element
330 undergoes elastic deformation. When the pressing force on the pressing element
310 is canceled, the reset element 330 extends to restore its shape and drives the
locking element 320 to move in the opposite direction until extending into the positioning
groove 110 via the second mounting hole 142 and, when the handheld structure 200 is
inserted in the positioning groove 110, being snap-fit with the operating handle 220,
while at the same time driving the pressing element 310 to return to position by the
interaction between the first slope 3221 and the second slope 3111. Thus, it can be
achieved that, each time a user mounts or removes the handheld structure 200, the
pressing element 310 and the locking element 320 timely return to position after releasing
the pressing element 310 so as to facilitate the next operation, which results in
convenient operation and good practicality.
[0066] Here, it should be noted that a spring has a simple manufacturing process, a low
cost, and a long life, as well as good elastic performance. Therefore, the reset element
330 can be arranged to be a spring.
[0067] In addition, in some embodiments, in reference to Figs. 1 to 4 and Figs. 9 and 10,
the cleaning device further comprises at least one elastic assembly 400 located in
the device body 100 and partially protruding into the positioning groove 110 so as
to abut against the operating handle 220. The elastic assembly 400 is configured to,
when the operating handle 220 disengages from being snap-fit with the device body
100, drive the part of the operating handle 220 in the positioning groove 110 to disengage
from the positioning groove 110.
[0068] It can be understood that, the elastic assembly 400 located in the device body 100
is configured to cooperate with a user to accomplish mounting and removal of the handheld
structure 200. Specifically, the elastic assembly 400 comprises a push pin 410 and
an elastic element 420 connected to the push pin 410. Similarly, the elastic element
420 can be a spring element. A wall of the positioning groove 110 is provided with
a passage hole 411 corresponding to the push pin 410. Thus, the push pin 410 can protrude
into the positioning groove 110 via the passage hole 411 so as to abut against the
operating handle 220. When the operating handle 220 is snap-fit with the locking element
320, the operating handle 220 pushes the push pin 410 into the device body 100 and
drives the elastic element 420 to be compressed. When the operating handle 220 disengages
from being snap-fit with the locking element 320, the elastic element 420 extends
and drives the push pin 410 to extend into the positioning groove 110, pushing the
operating handle 220 to detach from the positioning groove 110.
[0069] Thus, when the handheld structure 200 needs to be removed, the push pin 410 can push
the operating handle 220 to be exposed at an angle relative to the positioning groove
110 so as to facilitate full holding by a user and render it effortless to remove
it from inside the positioning groove 110, resulting in a simple structure and convenient
removal.
[0070] It should be noted that, the specific position of the elastic assembly 400 in the
device body 100 need ensure the movement direction of the elastic assembly 400 is
consistent with the direction in which the operating handle 220 detaches from the
positioning groove 110.
[0071] In addition, in reference to Fig. 1 and Figs. 4 to 7, an end face of the inserting
end 211 of the cleaning device provided by the present application has a first electrical
connector 2111. A bottom of the supporting groove 120 has a second electrical connector
121. The first electrical connector 2111 is configured to, when the inserting end
211 is inserted into the supporting groove 120, be electrically connected to the second
electrical connector 121.
[0072] Specifically, the first electrical connector 2111 is a female mating element arranged
at the side of an end face of the inserting end 211, and the second electrical connector
121 is a male mating element arranged at the same side as the bottom of the supporting
groove 120. As the female mating element is depressed relative to the end face, and
the male mating element protrudes relative to the bottom, insertion connection and
positioning of the inserting end 211 can be facilitated, and structural protrusion
of the inserting end 211 when the handheld structure 200 is used separately can be
reduced, so as to render the overall structure compact and reliable. In other embodiments,
the male and female mating elements can be reversed. This is not limited by the present
application.
[0073] Thus, by providing the first electrical connector 2111 and the second electrical
connector 121, when the inserting end 211 is inserted in the supporting groove 120,
an electrical connection between the handheld structure 200 and the device body 100
can be realized by means of the first electrical connector 2111 and the second electrical
connector 121. Thus, electrical control of the handheld structure 200's operating
state can be realized by means of an operating panel arranged on the device body 100
when the handheld structure 200 is connected to the device body 100 for use, without
the need to control the cleaning device's operation from the handheld structure 200,
so that the cleaning device is more flexible and convenient to use.
[0074] Further, still in reference to Fig. 1 and Figs. 4 to 7, in some embodiments, an end
face of the insertion end 211 has at least one first positioning element 2112. The
bottom of the supporting groove 120 has at least one second positioning element 122.
The first positioning element 2112 is configured to, when the inserting end 211 is
inserted in the supporting groove 120, be inserted to the second positioning element
122.
[0075] Thus, stability of the relative position and relative orientation between the inserting
end 211 and the supporting groove 120 can be ensured by the insertion connection between
the first positioning element 2112 and the second positioning element 122 when the
inserting end 211 and the supporting groove 120 are connected by insertion with each
other, improving accuracy in mounting the handheld structure 200.
[0076] In this embodiment, among the first positioning element 2112 and the second positioning
element 122, one is a positioning slot, and the other is a positioning block that
matches the positioning slot. By providing the positioning slot and the positioning
block that matches the positioning slot to form respectively the first positioning
element 2112 and the second positioning element 122, the structure of the first positioning
element 2112 and the second positioning element 122 can be rendered simple and compact,
and positioning by insertion can be rendered more efficient.
[0077] In addition, in the embodiment of the cleaning device provided by the present application,
in reference to Figs. 3 to 5 and Fig. 7 and Fig. 11, there is an air passage in the
handheld body 210, two ends of which form respectively an air inlet 212 located in
the center of an end face of the inserting end 211, and an air outlet 213 located
in a side face of the inserting end 211.
[0078] The device body 100 has an air admission passage 150 and an air discharge passage
160. An air outlet of the air admission passage 150 is located in the center of the
supporting groove 120 and correspondingly in communication with the air inlet 212.
An air inlet of the air discharge passage 160 is located in a side wall of the supporting
groove 120 and correspondingly in communication with the air outlet 213.
[0079] In reference to the schematic direction shown by the arrow in Fig. 11, when the device
body 100 and the handheld structure 200 of the cleaning device are used in combination,
air enters the handheld structure 200 via the air inlet 212 from the device body 100's
air admission passage 150, passes through the air passage, flows out of the air outlet
213, and then enters the air discharge passage 160 of the device body 100, and finally,
is blown out of the air discharge passage 160.
[0080] In this embodiment, as the air outlet 213 is located in a side face of the handheld
body 210, the air inlet 212 and the air outlet 213 are not located at the same end.
With the air discharge passage 160 being correspondingly in communication with the
air outlet 213, the air discharge passage 160 need not be arranged at an opposite
side of the end of the handheld structure 200 that has the air inlet 212. Thus, not
too much inner space of the device body 100 is occupied, which facilitates the design
and mounting of other structures of the body, provides more designable structural
space, and can also avoid an excessive size of the device body 100 while satisfying
an internal part structural design, facilitating the device body 100's use.
[0081] In addition, not providing the air inlet of the air discharge passage 160 in the
end face of the supporting groove 120 means the integrity of the end face of the supporting
groove 120 is not damaged too much, which can improve the supporting strength of the
end face of the supporting groove 120.
[0082] In some embodiments, in reference to Figs. 4 to 7, the cleaning device further comprises
a first sealing element 230 arranged between the air admission passage 150 and the
air inlet 212, a second sealing element 231 arranged between a side wall of the supporting
groove 120 and a side face of the inserting end 211, and a connector 232.
[0083] The first sealing element 230 and the second sealing element 231 are connected by
means of the connector 232. The first sealing element 230 and the connector 232 are
located in the same plane. The first sealing element 230, the second sealing element
231, and the connector 232 are formed integrally.
[0084] Specifically, the first sealing element 230 can be a rubber sealing ring, and the
second sealing element 231 can be a rubber sealing stripe. The rubber sealing ring
is glued to the inserting end 211 in a circumferential direction of the air inlet
212. The rubber sealing stripe is glued to a side face of the inserting end 211 in
a circumferential direction of the air outlet 213. Thus, sealing between the air admission
passage 150 and the air inlet 212 can be improved by means of the first sealing element
230, and sealing between the side wall of the supporting groove 120 and the side face
of the inserting end 211 can be improved by the second sealing element 231.
[0085] Further, the connector 232 can be two rubber stripes, which can be glued to the inserting
end 211. In addition, one end is connected to the first sealing element 230, and another
end is respectively connected to two opposite ends of the second sealing element 231,
so that the first sealing element 230, the second sealing element 231, and the connector
232 are formed integrally, which facilitates the mounting and manufacturing of the
first sealing element 230, the second sealing element 231, and the connector 232.
[0086] In addition, in some embodiments, in reference to Figs. 6 to 8 and Fig. 11, the handheld
body 210 comprises a housing 214, a support 215, and a driving element 216 used for
providing a suction force. The support 215 is partially inserted into the housing
214. The support 215 has a chamber inside. The driving element 216 is arranged in
the chamber. At least part of the support 215 and the housing 214 adjacent to the
support 215 form the inserting end 211.
[0087] Specifically, the driving element 216 is a relevant technology in the art and need
only be able to provide a suction force. Its structure is not unduly limited here.
[0088] On one hand, the support 215 provides a mounting position for the driving element
216, and on the other hand, part of the support 215 and the housing 214 adjacent to
the support 215 form the inserting end 211, putting it to multiple uses, which helps
reduce costs while causing the overall structure to have a high stability.
[0089] Further, still in reference to Figs. 6 to 8 and Fig. 11, a part of the chamber forms
the air passage. An end face of the support 215 facing an end face of the device body
100 forms the end face of the inserting end 211. The air inlet 212 corresponds to
a suction opening of the driving element 216. The air outlet 213 is located in a side
face of the support 215.
[0090] Thus, by forming the chamber mounted with the driving element 216 and serving as
the air passage by means of the support 215, with the air inlet 212 and the air outlet
213 formed in the support 215, and with the air outlet 213 provided in a side face,
the overall structure is simple and compact, resulting in a high space utilization
rate.
[0091] In some embodiments, in reference to Figs. 6 to 8 and Fig. 11, a side face of the
support 215 has a slot 240. An opening of the slot 240 faces a side wall of the supporting
groove 120 and forms the air outlet 213. The slot 240 has a first side wall 241 and
a second side wall 242 that are opposite to each other. The first side wall 241 faces
the handheld body 210. The second side wall 242 is provided with at least one through
hole that puts the air passage and the slot 240 in communication.
[0092] Specifically, the second side wall 242 is provided with two first through holes 2421
that put the air passage and the slot 240 in communication. Air is blown out of the
air outlet 213 via the first through holes 2421. The opening of the slot 240 faces
a side wall of the supporting groove 120. By making a slot 240 in a side wall of the
support 215 to form the air outlet 213, the structure is further rendered compact,
and full use is made of space.
[0093] In order to increase air flow, a snap-fit part 2423 is arranged in the slot 240.
A face of the snap-fit part 2423 facing the notch 2411 is provided with a second through
hole 2422, which also puts the air passage and the slot 240 in communication, so as
to increase the air flow surface of the slot 240, increasing air flow.
[0094] In addition, the snap-fit part 2423 is connected to the first side wall 241. Connecting
the snap-fit part 2423 with the first side wall 241 is equivalent to forming a reinforcing
rib at two side walls of the second through holes 2422, which, on one hand, guides
air in the second through hole 2422, and on the other hand, increases the snap-fit
part 2423's stability.
[0095] Here, it should be noted that, the slot 240 is an arc-shaped slot. The center of
the slot 240 coincides with the center of the end face of the inserting end 211. The
center angle of the slot 240 is smaller than 90°. Specifically, the center angle of
the slot 240 is larger than 30°. If the center angle of the slot 240 is too small,
air flow will be reduced. If it is too large, the overall strength of the support
215 will be damaged. In addition, an arc-shaped slot has a reduced wind resistance,
which helps air circulate.
[0096] In addition, in some embodiments, in reference to Fig. 11, the first side wall 241
is provided with a notch 2411 in communication with an end face of the support 215
facing the device body 100, so that the opening is inclined.
[0097] Thus, by causing the opening to be inclined by means of the notch 2411, the direction
of air blown out of the air outlet 213 is inclined axially outwards relative to the
handheld body 210, which reduces wind resistance while at the same time fully making
use of the structure's space, and is equivalent to blowing towards the air discharge
passage 160 at an angle.
[0098] In other embodiments, the cleaning device further comprises an outer connection structure
(not illustrated) configured to, when the handheld structure 200 detaches from the
device body 100, be connected to the handheld structure 200 and form, together with
the handheld structure 200, a cleaning executing device.
[0099] Thus, by providing the outer connection structure to connect with the separate handheld
structure 200 to form a cleaning executing device, the functions of the handheld structure
200 can be completed when using the handheld structure 200 separately, so as to improve
user experience when separately using the handheld structure 200. The outer connection
structure is configured to, when the handheld structure 200 detaches from the device
body 100, be connected to the handheld structure 200, and form, together with the
handheld structure 200, a cleaning executing device.
[0100] When the handheld structure 200 is used separately, it is connected to the outer
connection structure and forms a cleaning executing device, which puts it to multiple
uses, increases the utilization scenarios of the handheld structure 200, and improves
the handheld structure 200's functionality and applicability.
[0101] Further, the outer connection structure is a dust cup structure. Specifically, the
dust cup structure is snap-fit with the snap-fit part 2423. In this embodiment, the
dust cup structure is a relevant technology in the art. Its structure is not limited
here. Removable connection between the dust cup structure and the handheld structure
200 is achieved by means of the snap-fit part 2423, which facilitates utilization.
[0102] Thus, by providing a dust cup structure as the outer connection structure, the dust
cup structure can be used to receive dust and dirt sucked in by the handheld structure
200, which improves the handheld structure 200's cleaning efficiency and optimizes
a user's utilization experience.
[0103] With the cleaning device provided by the present application, when the handheld structure
200 is inserted in the device body 100, the inserting end 211 of the handheld body
210 is completely enveloped by the supporting groove 120 of the device body 100, a
part of a side face of the handheld body 210 is located in the positioning groove
110, and at least a part of the operating handle 220 is also located in the positioning
groove 110. Thus, the supporting groove 120 can guide the insertion of the inserting
end 211 and protect the connection between the inserting end 211 and the device body
100. The partial structure of the handheld structure 200 exposed outside the positioning
groove 110 and the supporting groove 120 can smoothly transition to an outer surface
of the supporting groove 120 and an outer surface of the positioning groove 110, enabling
the handheld structure 200 to be stably mounted in the device body 100 in a hidden
way, so that the cleaning device has a smooth overall styling, a compact structure,
and improved aesthetics.
[0104] Further, by providing the locking assembly 300 and its structure, it is further ensured
that the handheld structure 200 and the device body 100 are connected stably. And
by providing the elastic assembly 400, holding of the handheld structure 200 after
being unlocked is facilitated. Moreover, by appropriately arranging the opposite positions
of the air inlet 212 and the air outlet 213 of the inserting end 211, the relative
position and structure of the air admission passage 150 and the air discharge passage
160 of the device body 100 is changed so as to increase available space in the device
body 100, rendering the cleaning device more compact as a whole.
[0105] Finally, it should be noted that, the various embodiments above are merely used to
describe the technical solutions of the present application, instead of limiting it.
Although the present application has been described in detail with reference to the
above-described embodiments, a person of ordinary skill in the art should understand
that it is still possible to modify the technical solutions described in the above-described
