BACKGROUND
[0002] The existing liquid outlet device with descaling function generally adopts an extra
designed driving structure to drive the descaling structure to reciprocate so as to
descale the liquid outlet hole, which has high cost. The reciprocation of the descaling
structure requires a certain space, resulting in a large liquid residual space in
the liquid outlet device, which leads to the continuous dripping of residual liquid
from the liquid outlet hole after the liquid supply to the liquid outlet device is
stopped.

including:
a shell assembly provided with a liquid inlet channel and at least one liquid division
slot, wherein the liquid division slot is disposed on an outer surface of the shell
assembly; and
a liquid outlet assembly mounted to the shell assembly and overlaying each of the
liquid division slots, wherein the liquid outlet assembly includes an elastic member
corresponding to each of the liquid division slots, the elastic member is provided
with at least one liquid outlet hole, the shell assembly is provided with a descaling
member corresponding to each of the liquid outlet holes, each of the descaling members
is configured to pass through the corresponding liquid outlet hole;
wherein the elastic member is partially accommodated in the liquid division slot and
elastically abutted against the shell assembly, so as to divide the liquid division
slot into a first cavity communicated with the liquid inlet channel and a second cavity
communicated with the liquid outlet hole;
the elastic member is configured to elastically deform once a liquid pressure of the
first cavity exceeds a first preset value, so as to separate the elastic member from
the descaling member, so that the liquid inlet channel is communicated with the liquid
outlet hole through the first cavity and the second cavity in sequence; and the elastic
member can reset against the liquid pressure less than or equal to the first preset
value.
[0005] To achieve the above objects, the present application provides a liquid outlet system

[0006] The implementation of embodiments of the present application will have the following
beneficial effects.
[0007] The liquid division device of the above scheme is used and equipped in the liquid
outlet system, which can not only realize the descaling function for the liquid outlet
hole, but also reduce the descaling cost and the residual liquid in the liquid division
device by itself. Specifically, the liquid outlet device includes a shell assembly
provided with a liquid inlet channel and at least one liquid division slot, and a
liquid outlet assembly mounted to the shell assembly and overlaying each liquid division
slot. The liquid outlet assembly includes an elastic member disposed corresponding
to each liquid division slot and provided with at least one liquid outlet hole, and
the shell assembly is provided with a descaling member corresponding to each liquid
outlet hole, and each descaling member is configured to pass through the corresponding
liquid outlet hole. The elastic member can divide the liquid division slot into a
first cavity communicated with the liquid inlet channel and a second cavity communicated
with the liquid outlet hole. The elastic member elastically deforms once a liquid
pressure of the first cavity exceeds a first preset value, so as to separate the elastic
member from the descaling member, so that the liquid inlet channel is communicated
with the liquid outlet hole through the first cavity and the second cavity in sequence,
and the elastic member can reset against the liquid pressure less than or equal to
the first preset value (for example, when the liquid discharge of the liquid outlet
device is closed). In this way, the elastic member can move relative to the descaling
member, so as to realize descaling of the liquid outlet hole. The descaling cost is
low, no additional driving structure is needed, and the descaling member does not
need the space for reciprocation, thus reducing the space for liquid residue.

[0015] The existing liquid outlet device with descaling function generally adopts an extra
designed driving structure to drive the descaling structure to reciprocate so as to
descale the liquid outlet hole, which has high cost. The reciprocation of the descaling
structure requires a certain space, resulting in a large liquid residual space in
the liquid outlet device, which leads to the continuous dripping of residual liquid
from the liquid outlet hole after the liquid supply to the liquid outlet device is
stopped.
[0016] In order to solve the above technical problems, the embodiments of the present application
provide a liquid outlet device and a liquid outlet system. The liquid outlet system
can be mounted in various occasions and environments, such as companies, schools,
families, factories and the like, to realize cleaning effect and improve and enhance
life quality and health of people. The liquid outlet device may be, but is not limited
to, one or more combinations of a water outlet faucet, a shower head, a top sprayer
and a spray gun. For the convenience of describing the technical solutions of the
present application, the following takes the liquid outlet device being a shower head
as an example for illustration.
[0017] References are made to FIGS. 1-5 together to explain the liquid outlet system provided
by embodiments of the present application. The liquid outlet system includes a liquid
outlet device. The liquid outlet device includes a shell assembly 10 and a liquid
outlet assembly 20.
[0018] The shell assembly 10 is provided with a liquid inlet channel 100 and at least one
liquid division slot 200 disposed on the outer surface of the shell assembly 10. In
an embodiment of the present application, a plurality of liquid division slots 200
are provided. It is to be understood that in other embodiments one liquid division
slot 200 may be provided.
[0019] The liquid outlet assembly 20 is mounted to the shell assembly 10 and overlays each
liquid division slot 200. The liquid outlet assembly 20 includes an elastic member
21 disposed corresponding to each liquid division slot 200. The elastic member 21
may be made of an elastomeric material. In the embodiment of the present application,
a plurality of elastic members 21 are provided, and the plurality of elastic members
are arranged in one-to-one correspondence with the plurality of liquid division slots
200. The elastic member 21 is provided with at least one liquid outlet hole 300. In
an embodiment of the present application, each elastic member 21 is provided with
one liquid outlet hole 300. It is understood that in other embodiments, each elastic
member 21 may also be provided with a plurality of liquid outlet holes 300.
[0020] The shell assembly 10 is provided with a descaling member 30 corresponding to each
liquid outlet hole 300, and each descaling member 30 passes through the corresponding
liquid outlet hole 300. The elastic member 21 is partially accommodated in the liquid
division slot 200 and elastically abutted against the shell assembly 10, so as to
be able to divide the liquid division slot 200 into a first cavity 201 communicated
with the liquid inlet channel 100 and a second cavity 202 communicated with the liquid
outlet hole 300.
[0021] The elastic member 21 is configured to elastically deform once a liquid pressure
of the first cavity 201 exceeds a first preset value, so as to separate the elastic
member 21 from the descaling member 30, so that the liquid inlet channel 100 is communicated
with the liquid outlet hole 300 through the first cavity 201 and the second cavity
202 in sequence, thus achieving liquid discharge of the liquid outlet device. The
liquid outlet device can reset against the liquid pressure less than or equal to the
first preset value.
[0022] The liquid outlet system further includes a liquid inlet assembly. The liquid inlet
assembly is communicated with the liquid inlet channel 100 and is configured to supply
liquid to the liquid inlet channel 100. The liquid inlet assembly may be, but is not
limited to, a manually controlled or an electrically controlled valve configuration,
and the liquid inlet channel 100 is communicated with or disconnected from a liquid
source by opening or closing the liquid inlet assembly. The liquid includes, but is
not limited to, clear water or pure water from a municipal water network.
[0023] The first preset value can be set to satisfy that the elastic member 21 is separated
from the descaling member 30 under certain conditions, and the descaling member 30
passes through the corresponding liquid outlet hole 300 under certain conditions.
In an embodiment of the present application, the first preset value may be set to
be less than the liquid pressure when the liquid inlet assembly is opened to supply
liquid to the liquid inlet channel 100 and greater than the liquid pressure generated
by the liquid remaining in the first cavity 201 after the liquid inlet assembly is
closed. That is, after the liquid outlet device is opened, the liquid drives the elastic
member 21 to generate elastic deformation, so that the elastic member 21 is separated
from the descaling member 30. After the liquid outlet device is closed, the elastic
member 21 is reset, and the descaling member 30 passes through the corresponding liquid
outlet hole 300 again to complete the descaling of the liquid outlet hole 300.
[0024] In addition, since the elastic member 21 is elastically deformable, when the elastic
member 21 resets and the coaxiality of the descaling member 30 and the corresponding
liquid outlet hole 300 deviates, the liquid outlet hole 300 can be guided to the descaling
member 30 by means of the elastic deformability of the elastic member 21, so that
the descaling member 30 can pass through the corresponding liquid outlet hole 300.
[0025] To sum up, the implementation of the embodiments of the present application will
have the following beneficial effects: the liquid division device of the above schemes
is used and equipped in the liquid outlet system, which can not only realize the descaling
function for the liquid outlet hole 300, but also reduce the descaling cost and the
residual liquid in the liquid division device by itself. Specifically, the liquid
outlet device includes a shell assembly 10 provided with a liquid inlet channel 100
and at least one liquid division slot 200, and a liquid outlet assembly 20 mounted
to the shell assembly 10 and overlaying each liquid division slot 200. The liquid
outlet assembly 20 includes an elastic member 21, which is disposed corresponding
to each liquid division slot 200 and is provided with at least one liquid outlet hole
300. The shell assembly 10 is provided with a descaling member 30 corresponding to
each liquid outlet hole 300, and each descaling member 30 is configured to pass through
the corresponding liquid outlet hole 300. The elastic member 21 is capable of dividing
the liquid division slot 200 into a first cavity 201 communicated with the liquid
inlet channel 100 and a second cavity 202 communicated with the liquid outlet hole
300. The elastic member 21 elastically deform once a liquid pressure of the first
cavity 201 exceeds a first preset value, so as to separate the elastic member 21 from
the descaling member 30, so that the liquid inlet channel 100 is communicated with
the liquid outlet hole 300 through the first cavity 201 and the second cavity 202
in sequence. The elastic member 21 can reset against a liquid pressure less than or
equal to the first preset value (for example, when the liquid discharge of the liquid
outlet device is closed). Therefore, the elastic member 21 can move relative to the
descaling member 30, so as to realize descaling of the liquid outlet hole 300. The
descaling cost is low, no additional driving structure is needed, and the descaling
member 30 does not need the space for reciprocation, thus reducing the space for liquid
residue.
[0026] In an exemplary embodiment, referring to FIGS. 3 and 5 together, the elastic member
21 includes an annular arm 211 and a liquid outlet part 212. The liquid outlet hole
300 is disposed in the liquid outlet part 212. The annular arm 211 is annularly disposed
around the liquid outlet part 212, a circumferential outer side of the annular arm
211 is fixedly connected with the shell assembly 10. The annular arm 211 is at least
partially accommodated in the liquid division slot 200 and elastically abutted against
the shell assembly 10. The first cavity 201 is disposed around the annular arm 211,
and the annular arm 211 is disposed around the second cavity 202. In this way, the
liquid in the first cavity 201 can uniformly act on the annular arm 211, and the synchronization
of elastic deformation and reset at each position on the annular arm 211 is ensured,
thereby ensuring that the liquid outlet part 212 can move substantially in a straight
line relative to the descaling member 30, and ensuring the smoothness of the separation
of the liquid outlet part 212 from the descaling member 30 and the descaling member
30 passing through the liquid outlet hole 300 again. In addition, the annular arm
211 can surround the second cavity 202 to isolate the second cavity 202 from the first
cavity 201, so that the liquid remaining in the first cavity 201 is prevented from
entering the second cavity 202 and being discharged from the liquid outlet hole 300
when liquid discharge of the liquid outlet device is closed. The liquid outlet part
212 has a communication cavity 400 communicated between the second cavity 202 and
the liquid outlet hole 300. The descaling member 30 has a columnar shape. One end
of the descaling member 30 is disposed in the shell assembly 10 and accommodated in
the liquid division slot 200, and the other end of the descaling member 30 is configured
to pass through the corresponding liquid outlet hole 300 through the second cavity
202 and the communication cavity 400.
[0027] It may be understood that in other embodiments, a component of the elastic member
21 configured to isolate the first cavity 201 and the second cavity 202 may also be
of a non-annular structure, and the first cavity 201 and the second cavity 202 may
be isolated from each other by the component mating with the shell assembly 10. At
this time, one end of the descaling member 30 disposed in the shell assembly 10 may
be accommodated in the liquid division slot 200 or disposed outside the liquid division
slot 200.
[0028] In an exemplary embodiment, as shown in FIG. 5, the shell assembly 10 is provided
with a mounting hole 500 corresponding to each of the liquid outlet parts 212, and
each of the liquid outlet parts 212 is mounted to and movable relative to the corresponding
mounting hole 500. In this way, the liquid outlet part 212 can be positioned by providing
the mounting hole 500, and the position of the liquid outlet part 212 relative to
the shell assembly 10 can be ensured to be stable. Furthermore, the providing of the
mounting hole 500 enables the liquid outlet part 212 mounted in the mounting hole
500 to be guided by the shell assembly 10, thereby ensuring the stability of the movement
of the liquid outlet part 212 relative to the descaling member 30. A side of the annular
arm 211 facing away from the liquid division slot 200 has an annular groove 1000 disposed
coaxially with the annular arm 211 to improve the elastic deformability of the annular
wall 211.
[0029] In an exemplary embodiment, with continued reference to FIG. 5, the mounting hole
500 includes a columnar segment 501 and a conical segment 502. The conical segment
502 has a large end facing the annular arm 211 and a small end away from the annular
arm 211, so that there can be a space for the elastic deformation of the annular arm
211 by providing the conical segment 502. A conical surface of the conical segment
502 formed in the shell assembly 10 can avoid excessive elastic deformation of the
annular arm 211 and ensure smooth reset of the elastic member 21.
[0030] The columnar segment 501 communicates with the small end. A columnar surface of the
columnar segment 501 formed in the shell assembly 10 can restrict the movement of
the liquid outlet part 212 and serve as a guide. With the above arrangement, the mounting
hole 500 can reduce the contact area between the hole wall (conical surface and columnar
surface as a whole) and the elastic member 21, and avoid a high friction resistance
between the elastic member 21 and the hole wall which affects the normal elastic deformation
and reset of the elastic member 21 while playing a role of guiding. As shown in FIG.
3, in the embodiment of the present application, the liquid outlet part 212 has a
cylindrical structure. It may be understood that in other embodiments, the liquid
outlet part 212 may also have a columnar structure with other cross-sectional shapes.
[0031] In an exemplary embodiment, as shown in FIGS. 3 and 5, the descaling member 30 includes
a connecting part 31 and a descaling part 32. The descaling part 32 is disposed in
the shell assembly 10 by the connecting part 31 and can pass through the corresponding
liquid outlet hole 300 to descale the liquid outlet hole 300. An outer wall of the
connecting part 31 has an arc shape, so as to reduce the resistance to the liquid,
thereby preventing the descaling member 30 from vibrating under the drive of the liquid.
[0032] In an exemplary embodiment, referring to FIG. 3 and FIG. 5 to FIG. 8 together, the
liquid outlet assembly 20 further includes a body 22 fixedly connected to the shell
assembly 10, and a side of the body 22 facing the liquid division slot 200 is fit
against the shell assembly 10 and the side and the shell assembly 10 enclose and form
a liquid outlet channel 600, through which the liquid inlet channel 100 and the liquid
division slot 200 are communicated. The body 22 is made of an elastomeric material,
and the shell assembly 10 can clamp the body 22 from a side of the body 22 facing
the liquid division slot 200 and a side of the body 22 facing away from the liquid
division slot 200. The shell assembly 10 can clamp the body 22, which can ensure that
the body 22 is kept at a stable position under the impact of liquid, thereby ensuring
that the shape of the liquid division slot 200 remains unchanged, so that the liquid
can flow along a preset direction.
[0033] In this way, the liquid can enter the first cavity 201 through the adjustment and
guidance of the liquid outlet channel 600, so that the liquid flow has certain directivity
and smoothness, and the liquid can flow rapidly to the liquid division slot 200. As
shown in FIGS. 6 and 7, the liquid outlet channel 600 may form a groove structure
601 in the body 22 and be overlaid by the shell assembly 10. As shown in FIGS. 3 and
8, the liquid outlet channel 600 may form a groove structure 601 in the shell assembly
10 and be overlaid by the body 22. It may be understood that in other embodiments,
the liquid outlet channel 600 may also form groove structures 601 in the body 22 and
the shell assembly 10, respectively, and the groove structures 601 enclose and form
the liquid outlet channel 600.
[0034] In an exemplary embodiment, referring to FIG. 4, FIG. 6 and FIG. 7 together, the
liquid inlet channel 100 can form a liquid discharge opening 101 in the shell assembly
10, and the liquid outlet assembly 20 also includes a protrusion part 23. The circumferential
outer side of the protrusion part 23 is connected with the body 22. The protrusion
part 23 is disposed opposite to the liquid discharge opening 101 and elastically abuts
against the shell assembly 10 to seal the liquid discharge opening 101. The protrusion
part 23 is configured to elastically deform when the liquid pressure of the liquid
inlet channel 100 exceeds a second preset value, so that the liquid discharge opening
101 communicates with the liquid outlet channel 600. The protrusion part 30 can reset
against the liquid pressure less than or equal to the second preset value.
[0035] The protrusion part 23 can elastically abut against the shell assembly 10 to seal
the liquid discharge opening 101 disposed opposite to the protrusion part 23, so that
the liquid can act positively on the protrusion part 23 when the liquid pressure of
the liquid inlet channel 100 exceeds the second preset value, thus ensuring the uniformity
of elastic deformation of the protrusion part 23, ensuring the synchronization of
elastic deformation of each portion of the protrusion part 23, and avoiding the protrusion
part 30 from being unable to reset due to excessive local deformation. The protrusion
part 23 can reset against a liquid pressure less than or equal to the second preset
value (for example, when the liquid discharge of the liquid outlet device is closed),
thereby ensuring the sealing of the liquid discharge opening 101 and preventing the
liquid remaining in the liquid inlet channel 100 from being discharged from the liquid
discharge opening 101 and into the liquid outlet channel 600. Meanwhile, the liquid
remaining in the liquid outlet channel 600 cannot continue to flow into the first
cavity 201 and be discharged from the liquid outlet hole 300 due to isolation between
the first cavity 201 and the second cavity 202 by the elastic member 21. The liquid
in the liquid outlet hole 300 cannot be discharged from the liquid outlet hole 300
under an action of atmospheric pressure, a self-adsorption capacity, shape of the
liquid outlet hole 300, etc., so that the residual liquid cannot be discharged from
the liquid outlet hole 300 after the liquid discharge of the liquid outlet device
is closed, and the user experience is improved. Since the body 22 is fixedly connected
to the shell assembly 10, a circumferential outer side of the protrusion part 23 is
connected to the body 22, ensuring the position accuracy of the protrusion part 23
during the elastic deformation and reset process, thereby ensuring that the elastic
deformation and reset can be stably performed.
[0036] The second preset value can be set to satisfy that the liquid discharge opening 101
is communicated with the liquid outlet channel 600 under certain conditions, and the
liquid discharge opening 101 is disconnected from the liquid outlet channel 600 under
certain conditions. In an embodiment of the present application, the second preset
value may be set to be less than the liquid pressure when the liquid inlet assembly
is opened to supply liquid to the liquid inlet channel 100 and greater than the liquid
pressure generated by the liquid remaining in the liquid inlet channel 100 after the
liquid inlet assembly is closed. That is, the liquid drives the protrusion part 23
to elastically deform after liquid discharge of the liquid outlet device is opened,
so that the liquid discharge opening 101 communicates with the liquid outlet channel
600; and the protrusion part 23 is reset after the liquid discharge of the liquid
outlet device is closed, so as to ensure the sealing of the liquid discharge opening
101 and prevent the liquid remaining in the liquid inlet channel 100 from being discharged
from the liquid discharge opening 101 and into the liquid outlet channel 600.
[0037] In an exemplary embodiment, referring to FIG. 4, FIG. 6 and FIG. 7 together, a side
of the protrusion part 23 facing away from the liquid discharge opening 101 has a
cavity 700. Thus, the arrangement of the cavity 700 can increase the elastic deformation
of the protrusion part 23 generated when the liquid pressure of the liquid inlet channel
100 exceeds the second preset value, thereby ensuring the communication between the
liquid discharge opening 101 and the liquid outlet channel 600. In addition, in some
exemplary embodiments, the protrusion part 23 may also be a solid structure that elastically
deforms with its own elastic deformation capability when the liquid pressure of the
liquid inlet channel 100 exceeds the second preset value. It may be understood that
in other embodiments a reset member may also be provided in the cavity 700 to enhance
a reset performance of the protrusion part 23. The reset member can be a spring or
an elastic structure made of other elastic materials. The elastic deformation ability
of the protrusion part 23 can be adjusted by changing parameters, such as its material
and size.
[0038] In an exemplary embodiment, referring to FIG. 6 and FIG. 7 together, the shell assembly
10 is provided with an accommodating groove 800, the liquid outlet channel 600 is
communicated with the accommodating groove 800. The protrusion part 23 is at least
partially received in the accommodating groove 800. The protrusion part 23 is configured
to elastically deform when the liquid pressure of the liquid inlet channel 100 exceeds
the second preset value, so that the liquid discharge opening 101 is communicated
with the accommodating groove 800. In this way, by the arrangement of the accommodating
groove 800, at least a portion of the protrusion part 23 can be accommodated by the
accommodating groove 800, so that during the elastic deformation and reset of the
protrusion part 23, the accommodating groove 800 plays a limiting and guiding role
to ensure that the elastic deformation and reset can be achieved as desired, thereby
ensuring that the liquid discharge opening 101 and the liquid outlet channel 600 can
communicate with each other after the elastic deformation of the protrusion part 23,
and ensuring that the liquid discharge opening 101 can be sealed after the protrusion
part 23 is reset.
[0039] In an exemplary embodiment, referring to FIG. 6 and FIG. 7 together, the protrusion
part 23 is at least partially accommodated in the liquid discharge opening 101 to
further enhance the sealing of the protrusion part 23 to the liquid discharge opening
101. The liquid discharge opening 101 also can play a limiting and guiding role for
the protrusion part 23, ensuring that the elastic deformation and reset of the protrusion
part 23 can meet expectations during the elastic deformation and reset of the protrusion
part 23. Meanwhile, the protrusion part 23 is at least partially accommodated in the
liquid discharge opening 101, so that a gap is easily generated between the protrusion
part 23 and the shell assembly 10 after the protrusion part 23 is elastically deformed,
so as to facilitate rapid communication between the liquid discharge opening 101 and
the liquid outlet channel 600.
[0040] In an exemplary embodiment, referring to FIG. 6 and FIG. 7 together, the liquid outlet
channel 600 is communicated with the cavity 700, so that when the protrusion part
23 is elastically deformed, the air in the cavity 700 can be discharged through the
liquid outlet channel 600, which facilitates the elastic deformation of the protrusion
part 23 and ensures smooth communication between the liquid discharge opening 101
and the liquid outlet channel 600. After the liquid outlet device is closed, the liquid
pressure of the liquid inlet channel 100 is less than or equal to the second preset
value, the protrusion part 23 is reset, and the air in the liquid outlet channel 600
enters the cavity 700 under the action of atmospheric pressure, so as to ensure that
the protrusion part 23 can be completely reset. At the same time, after the air in
the liquid outlet channel 600 enters the cavity 700, the outside air is replenished
into the liquid outlet channel 600 through the liquid outlet hole 300, while the liquid
remaining in the liquid outlet hole 300, the liquid division slot 200 and the liquid
outlet channel 600 is pushed to flow toward a side away from the liquid outlet hole
300, further preventing the residual liquid from being discharged from the liquid
outlet hole 300. In addition, the communication between the liquid outlet channel
600 and the cavity 700 can further prevent excessive pressure in the cavity 700 which
damages the stability of the connection between the shell assembly 10 and the liquid
outlet assembly 20.
[0041] In an exemplary embodiment, referring to FIG. 3, FIG. 6 to FIG. 8 together, a plurality
of liquid outlet channels 600 are provided, and the multiple liquid outlet channels
600 are provided around the protrusion part 23. Because the protrusion part 23 is
disposed opposite to the liquid discharge opening 101, the liquid can uniformly enter
each liquid outlet channel 600 after driving the protrusion part 23 to elastically
deform, thus providing the possibility for the liquid outlet device to uniformly discharge
liquid subsequently. A plurality of liquid division slots 200 are provided, and each
liquid outlet channel 600 is communicated with at least one liquid division slot 200.
[0042] In an exemplary embodiment, referring to FIG. 6 and FIG. 7 together, a side of the
protrusion part 23 facing the liquid discharge opening 101 has a guide surface 231
which is configured to be elastically deformed with the protrusion part 23 to guide
the liquid to the liquid outlet channel 600. In this way, the arrangement of the guide
surface 231 can facilitate the liquid to enter the liquid outlet channel 600, thereby
guiding the flow direction of the liquid to a certain extent.
[0043] In an exemplary embodiment, as shown in FIG. 6, the guide surface 231 is a spherical
crown. This enables a linear seal to be formed between the protrusion part 23 and
the shell assembly 10. At this time, the top end of the protrusion part 23 is located
in the liquid inlet channel 100 and seals the liquid discharge opening 101. In an
embodiment of the present application, the shell assembly 10 is provided with an accommodating
groove 800. The remaining portion of the protrusion part 23 is located in the accommodating
groove 800, so that through the arrangement of the accommodating groove 800, the accommodating
groove 800 plays a limiting and guiding role during the elastic deformation and reset
of the protrusion part 23, thus ensuring that the elastic deformation and reset can
meet expectations, and further ensuring that the liquid discharge opening 101 and
the liquid outlet channel 600 can communicate after the protrusion part 23 is elastically
deformed, and ensuring that the liquid discharge opening 101 can be sealed after the
protrusion part 23 is reset. In addition, in some exemplary embodiments, the protrusion
part 23 may also form a linear seal with a groove opening of the accommodating groove
800 formed in the shell assembly 10 to prevent residual liquid in the accommodating
groove 800 from entering the liquid outlet channel 600.
[0044] In another exemplary embodiment, as shown in FIG. 7, the protrusion part 23 includes
a circumferential wall 232 and a connection wall 233. The circumferential wall 232
is bent toward the connection wall 233 and connected with a periphery of the connection
wall 233 to form a guide surface 231 on a side of the circumferential wall 232 facing
away from the connection wall 233. This enables an end face sealing to be formed between
the protrusion part 23 and the shell assembly 10. At this time, the protrusion part
23 is integrally positioned outside of the liquid inlet channel 100 and seals the
liquid discharge opening 101. In an embodiment of the present application, the shell
assembly 10 is provided with an accommodating groove 800. The protrusion part 23 can
be integrally located in the accommodating groove 800, so that the accommodating groove
800 plays a limiting and guiding role in the elastic deformation and reset processes
of the protrusion part 23 through the arrangement of the accommodating groove 800,
ensuring that the elastic deformation and reset can meet expectations, thereby ensuring
that the liquid discharge opening 101 and the liquid outlet channel 600 can communicate
after the protrusion part 23 is elastically deformed, and ensuring that the liquid
discharge opening 101 can be sealed after the protrusion part 23 is reset. The liquid
acts on the connection wall 233 in order that the circumferential wall 232 bends toward
the connection wall 233, so that the guide surface 231 directly faces the liquid discharge
opening 101 to guide the liquid to the liquid outlet channel 600. The protrusion part
23 can seal by sealing means other than linear sealing and end face sealing.
[0045] As shown in FIG. 7, the circumferential wall 232 and the connection wall 233 can
enclose and form a notch 900. The notch 900 is disposed opposite to the liquid discharge
opening 101. In this way, through the arrangement of the notch 900, the action position
of the liquid acting on the protrusion part 23 can be positioned, which facilitates
that the protrusion part 23 can elastically deform according to a preset, so that
each portion of the circumferential wall 232 can be elastically deformed synchronously,
and the fluid can enter the multiple liquid outlet channels 600 at the same time,
thus improving the liquid outlet effect of the liquid outlet device.
[0046] In an exemplary embodiment, referring to FIG. 3 and FIG. 8 together, the liquid outlet
channel 600 extends at least partially offset from a radial direction of the protrusion
part 23, such that the liquid outlet channel 600 can accommodate more residual liquid,
further avoiding the discharge of residual liquid from the liquid outlet hole 300.
[0047] In an exemplary embodiment, referring to FIGS. 1, 2 and 4-8 together, the shell assembly
10 includes a face cover 11, a rear shell 12, an inner bracket 13, a ball head 14,
a ball head sleeve 15, and a nut 16. The face cover 11 and the rear shell 12 enclose
and form a mounting space, the inner bracket 13 and the liquid outlet assembly 20
are mounted in the mounting space. The inner bracket 13 is connected with the rear
shell 12, and the liquid outlet assembly 20 can be abutted against the face cover
11, so that the inner bracket 13 and the face cover 11 can clamp the liquid outlet
assembly 20. The liquid division slot 200 is provided in the inner bracket 13. The
descaling member 30 is provided in the inner bracket 13 and partially located in the
liquid division slot 200. The mounting hole 500 is provided in the face cover 11.
The inner bracket 13 and the body 22 enclose and form a liquid outlet channel 600.
[0048] The liquid inlet channel 100 penetrates through the ball head 14 and extends into
the inner bracket 13, a liquid discharge opening 101 is formed in the inner bracket
13. The nut 16 is in threaded connection with the inner bracket 13 to press the ball
head 14 on the inner bracket 13 through the ball head sleeve 15, so as to restrict
the movement of the ball head 14 relative to the inner bracket 13. Meanwhile, the
ball head 14 is fit against the arc-shaped surface of the ball head sleeve 15 to facilitate
the rotation of the ball head 14 relative to the inner bracket 13, so as to adjust
the orientation of the face cover 11 and further adjust the direction of liquid discharge.
In order to reduce the wear when the ball head 14 rotates relative to the inner bracket
13, a gasket 17 is further provided between the ball head 14 and the inner bracket
13. At the same time, a sealing member 18 is further provided between the gasket 17,
the inner bracket 13, and the ball head 14, to prevent liquid from being discharged
between the inner bracket 13 and the ball head 14. In order to save water resources,
a flow limiting sheet 19 is further provided in the liquid inlet channel 100 to keep
the liquid outlet amount of the liquid outlet device constant and save the liquid
consumption.
