FIELD OF THE INVENTION
[0001] The present invention relates to a liquid soap structure, and particularly to a liquid
soap valve structure for preventing liquid soap leakage.
BACKGROUND OF THE INVENTION
[0002] A soap supplying device is categorized into a manual soap discharge type and an automatic
soap discharge type. A manual soap supplying device usually includes a soap conduit.
The soap conduit communicates with a liquid soap container as well as a pressure device
having a liquid soap pipe. The liquid soap pipe includes a pressure receiving section
having a liquid soap chamber, a pressure applying section movable relative to the
pressure receiving section and to apply pressure to the pressure receiving section,
and check valves respectively disposed at two ends of the liquid soap pipe. The soap
supplying device further includes a press section for a user to press thereupon to
further operate the pressure receiving section. By butting the liquid soap chamber
in the pressure receiving section through the pressure applying section, liquid soap
in the liquid soap chamber is delivered and discharged to a hand of the user along
the liquid soap pipe. An automatic soap supplying device of the prior art usually
incorporates the above manual soap supplying device, which cooperates with an additional
motor-driven automatic press device. As the automatic press device operates at the
press section or the pressure applying section, pressure is automatically applied
on the pressure receiving section by the pressure applying section to achieve liquid
soap supply. Further, to adapt to a wall-mounted soap supplying device and habits
of hand operations of users, a soap supplying device having a soap discharge opening
facing downwards is developed.
[0003] A check valve device corresponding to a soap discharge opening is usually made of
a plastic valve disposed at the soap discharge opening. By use of an elastic member,
the plastic valve presses tightly against an inner wall of the soap discharge opening.
When a press initiated by a user or when an automatic press device is applied, the
plastic valve disengages from the inner wall to allow the liquid soap to pass through
the liquid soap pipe to reach the soap discharge opening. Although the above structure
is suitable for a soap supplying device that discharges the soap in an upward direction,
complications are however incurred when implementing the above structure to a soap
supplying device that discharges the soap in a downward direction. First of all, the
liquid soap in an inverted-style liquid soap container applies a pressure to push
the plastic valve due to gravitational force. In order to prevent the liquid soap
from leaking through a gap between the plastic valve and the inner wall to drip onto
the ground, the strength of the elastic member needs to be reinforced to render even
greater tightness between the plastic valve and the inner wall. However, the increased
strength of the elastic valve at the same time raises the level of force that needs
to be applied for operating the pressure applying section. For example, a motor of
a battery-driven automatic soap supplying device may not function properly due to
insufficient power from the battery, such that the press section or the pressure applying
section is not successfully propelled. Further, in a plug-in automatic soap supplying
device that is free of the above issue of insufficient power from the battery, since
the plastic valve is in prolonged and constant friction with the soap discharge opening,
contact planes of the plastic valve and the soap discharge opening can easily become
worn out. Thus, a gap between the contact planes of the plastic valve and the soap
discharge opening is formed such that the liquid soap is guided through the gap to
drip via the soap discharge opening.
[0004] The Taiwan Patent No.
579820 discloses a soap supplying device as described above. The soap supplying device includes
a liquid soap pipe. The liquid soap pipe respectively has a liquid soap entrance and
a liquid soap exit at two ends thereof. Further, the liquid soap pipe includes a roller
valve at one end corresponding to the liquid soap entrance, and a plastic valve at
one end corresponding to the liquid soap exit. The plastic valve is pushed by an elastic
member to butt against an inner wall around the liquid soap exit on the liquid soap
pipe. In this prior art, the above issue of the leaked liquid soap dripping to the
ground due to inadequate tightness between the plastic valve and the inner wall of
the liquid soap exit caused by the insufficiently powered motor or the wear of the
plastic valve and the inner wall is lively generated
[0005] EP 2 082 809 A relates to a foam pump which defines the closest state of the art and includes a
piston housing and a piston assembly received in the piston housing thereby defining
a collapsible liquid chamber and a collapsible air chamber. The piston assembly includes
a premix chamber separated from both the collapsible liquid chamber and the collapsible
air chamber by a premix chamber wall and fluidly communicating with both the collapsible
liquid chamber and the collapsible air chamber through a mix aperture in the premix
chamber wall. A biasing member urges the piston assembly to a non-actuated position.
The foam pump is actuated by urging the piston assembly against the biasing member
to an actuated position in which the collapsible air chamber and the collapsible liquid
chamber are reduced in volume such that air and foamable liquid are expelled from
their respective collapsible air chamber and collapsible liquid chamber through the
mix aperture. The simultaneous movement of the air and foamable liquid through the
mix aperture causes a turbulent mixing thereof. The documents

EP 1847 327 A,
EP 2 127581A1 and
EP 2462852A1 disclose Alternative embodiments of soap dispenser.
SUMMARY OF THE INVENTION
[0006] Therefore the primary object of the present invention is to provide a power-saving
liquid soap valve for effectively eliminating liquid soap leakage.
[0007] The above object is achieved by a liquid soap dispenser according to claim 1.
[0008] Further, the elastic washer may be made of a rubber material.
[0009] Further, the soap discharging valve may include a limiting end located at one end
of the axle strut relative to the tightening end.
[0010] Further, the air supply valve may include a supporting plate linking with the soap
discharging tube and having the air supply channel, and an elastic valve disposed
on the supporting plate. The elastic valve includes an outer ring pressing against
a wall of the outer housing corresponding to the air chamber, and an elastic section
covering the air supply channel.
[0011] Further, the elastic valve may be made of a rubber material.
[0012] Further, the liquid soap conduit may include an elastic member encircling the soap
entering tube and the soap discharging tube.
[0013] Further, the liquid soap conduit may include a check valve disposed at the liquid
soap entrance.
[0014] Further, the check valve may include a soap entering opening communicating with the
liquid soap entrance and the soap entering tube, a stopping member formed at an outer
diameter greater than an inner diameter of the soap entering opening, and at least
one protruding section disposed in the soap entering opening to support the stopping
member.
[0015] Further, the stopping member may be made of a rubber material.
[0016] Further, the elastic washer may include a deformation region surrounding the through
hole.
[0017] Further, the foam discharging tube may include a press section, and a pressure applying
section linking with the press section to push the air supply valve.
[0018] Further, the foam discharging tube may include a foaming filter disposed at the foam
exit.
[0019] Therefore, through the deformation between the elastic washer and the pressing member
of the soap discharging valve, the liquid soap exit can be controlled to open or close.
Thus, with only a small force applied to the automatic press device, the liquid soap
chamber is pressurized to cause deformation of the elastic washer so that a passage
allowing the liquid soap to pass through is generated. Further, as the elastic washer
is made of a rubber material, the liquid soap is more effectively prevented from leaking
along the wall of the liquid soap exit. Moreover, the air supply valve of the present
invention allows the soap discharging tube to restore to its initial position when
being pressed by the elastic member. Meanwhile, through the negative pressure in the
air chamber, the residual liquid soap at the foam exit and the gas-liquid mixing chamber
is sucked back to the air chamber via the air supply channel, thereby preventing the
residual liquid soap from dripping to the ground and maintaining tidiness of an operation
environment.
[0020] The foregoing, as well as additional objects, features and advantages of the invention
will be more readily apparent from the following detailed description, which proceeds
with reference to the accompanying drawings.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS
[0022] FIG. 1 is a schematic diagram of an anti-leakage liquid soap valve structure according
to an embodiment of the present invention cooperating with an automatic soap supplying
device. Referring to FIG. 1, an anti-leakage liquid soap valve structure 100 according
to an embodiment of the present invention is applied in cooperation with a wall-mounted
automatic soap supplying device. The wall-mounted automatic soap supplying device
includes a liquid soap container 40 and an automatic press device 50. The automatic
press device 50 is disposed below the liquid soap container 40 and is powered by electricity.
The liquid soap container 40 includes an accommodating section 41 for accommodating
liquid soap 42, and a liquid soap entrance 43 communicating with the accommodating
section 41 and facing downwards. At a position corresponding to the liquid soap entrance
43, the automatic press device 50 includes a holding region to hold the anti-leakage
liquid soap valve structure 100 of the present invention. The automatic press device
50 further includes a holding region formed correspondingly to the liquid soap entrance
43 to hold the anti-leakage liquid soap valve structure 100 and a butting element
51 that is controlled by a driving motor (not shown) to swing up and down. A press
section 33 is located at one end of the anti-leakage liquid soap valve structure 100
to engage with the butting element 51, thereby forming the automatic soap supplying
device with an exit facing downwards.
[0023] FIGS. 2 and 3 show exploded views of an anti-leakage liquid soap valve structure
of the present invention; FIG. 4A shows a schematic diagram of gas-liquid mixture
in an anti-leakage liquid soap valve structure of the present invention. Referring
to FIGS. 2, 3 and 4A, an anti-leakage liquid soap valve structure 100 of the present
invention includes a liquid soap conduit for accommodating the liquid soap 42 in the
liquid soap container 40 and discharging the liquid soap 42 by pressure, an air conduit
for accommodating air and discharging the air by pressure, and a foam discharging
tube 30 for receiving and mixing the liquid soap 42 of the liquid soap conduit and
the air of the air conduit to produce a foamed liquid soap. The liquid soap conduit
includes a soap entering tube 212 communicating with the liquid soap entrance 43 to
receive the liquid soap 42, a soap discharging tube 24 communicating with the soap
entering tube 212 and having a liquid soap chamber 243 to allow the soap entering
tube 212 to push forwards, a liquid soap exit 244 located at one end of the soap discharging
tube 24 relative to the liquid soap entrance 43, a soap discharging valve 25, and
a positioning member 26 located at the liquid soap exit 244 to clamp the soap discharging
valve 25 with the liquid soap exit 244 from two sides. The soap discharging valve
25 includes an elastic washer 255 disposed at the liquid soap exit 244, and a pressing
member pressing against an inner junction plane of the elastic washer 255. The air
conduit includes an outer housing 20 encircling the liquid soap conduit to form an
air chamber 28 therewith, an air exit located at one side of the air chamber 28, and
an air supply valve linking with the soap discharging tube 24 and discharging the
air from the air chamber 28 to the air exit 245. The outer housing 20 is formed by
an upper half 21 and a lower half 21. The air supply valve includes at least one air
supply channel 242 for discharging the air in the air chamber 28 towards the other
side of the air chamber 28. The foam discharging tube 30 includes a gas-liquid mixing
chamber 311 located at the liquid soap exit 244 and the air exit 245 and formed by
an encircling soap chamber wall 31, a foam exit 35 communicating with the gas-liquid
mixing chamber 311, and a foaming filter 34 disposed at the foam exit 35. To allow
the air supply valve to move within the air chamber 28, and to drive the soap discharging
tube 24 to move relative to the soap entering tube 212 by the air supply valve, the
foam discharging tube 30 includes a pressure applying section 32 linking with the
press section 33 to push the air supply valve. To confine the pressure applying section
32 within the outer housing 20, the outer housing 20 includes a limiting section 221
that butts the pressure applying section 32 to limit the pressure applying section
32 within the outer housing 20. Further, to enable the air supply valve and the soap
discharging tube 24 to restore to their initial positions, the liquid soap conduit
includes an elastic member 29 encircling the soap entering tube 212 and the soap discharging
tube 24. The elastic member 29 has two ends butting against the inner wall of the
air chamber 28 and connecting to the soap discharging tube 24. By storing the force
applied to the pressure applying section 32, elasticity for restoring the soap discharging
tube 24 and the air supply valve back to their initial positions is provided.
[0024] The elastic washer 255 has a through hole 256. The pressing member includes an axle
strut 254 penetrating through the through hole 256, a tightening end 251 connected
to the axle strut 254 to press against an inner junction plane of the elastic washer
255 corresponding to the liquid soap entrance 43, and a limiting end 257 located at
the axle strut 254 relative to the tightening end 251. The elastic washer 255 includes
a deformation region 258 surrounding the through hole 256 to promote deformation of
the elastic washer 255. The tightening end 251 includes at least two butting members
252 butting against one side of the elastic washer 255 corresponding to the liquid
soap entrance 43, and at least one spacing region 253 formed between the two butting
members 252. With the above configuration, the soap discharging valve 25 of the liquid
soap conduit forms an exit for allowing the liquid soap 42 to pass through the deformation
thereof. Thus, when pressure is applied by the soap entering tube 212 to the liquid
soap chamber 243 of the soap discharging tube 24, the pressing member of the soap
discharging valve 25 is pressed to move downwards, and further presses the through
hole 256 to deform and expand until the elastic washer 255 contacts the limiting end
257. At this time, the spacing region 253 between the two butting members 252 communicates
with the expanded through hole 256 to form a passage for the liquid soap 42 to pass
through. To steadily fit the elastic washer 255 around the axle strut 254, the elastic
washer 255 is preferably made of a rubber material. As the rubber material expands
when being humidified, the elastic washer 255 is able to more steadily fit around
the axle strut 254 to prevent the liquid soap 42 from leaking via the through hole
256.
[0025] Moreover, to prevent the liquid soap 42 from reflowing into the liquid soap container
40 via the liquid soap entrance 43 when pressure is applied to the soap discharging
tube 24 by the soap entering tube 212, the liquid soap conduit further includes a
check valve 10 disposed at the liquid soap entrance 43. The check valve 10 includes
a soap entering opening 11 communicating with the liquid soap entrance 43 and the
soap entering tube 212, a stopping member 12 formed at an outer diameter greater than
an inner diameter of the soap entering opening 11, and at least one protruding section
211 disposed in the soap entering opening 11 to support the stopping member 12. The
stopping member 12 is preferably made of a rubber material. An airtight ring 23 is
disposed between the soap entering tube 212 and the soap discharging tube 24 to separate
the liquid soap chamber 243 and the air chamber 28. When pressure is applied by the
soap entering tube 212 to the soap discharging tube 24, the liquid soap 42 in the
liquid soap chamber 243 flows towards the liquid soap entrance 43 and the liquid soap
exit 244. At this time, the check valve 10 disposed at the liquid soap entrance 43
moves towards the liquid soap entrance 43 due to the pressure in the liquid soap chamber
243. Since the outer diameter of the stopping member 12 is greater than the inner
diameter of the soap entering opening 11, the stopping member 12 blocks on the soap
entering opening 11 to allow the liquid soap 42 to flow towards the liquid soap exit
244.
[0026] To facilitate delivery of the air from the air chamber 28 to the air exit 245, the
air supply valve includes a supporting plate 241 and an elastic valve 27. The supporting
plate 241 is linked with the soap discharging tube 24, and includes the air supply
channel 242. The elastic valve 27 includes an outer ring 271 pressing against a wall
of the outer housing 20 corresponding to the air chamber 28, and an elastic section
272 covering the air supply channel 242. When the supporting plate 241 is pressed
to move towards an upper end of the air chamber 28, the outer ring 271 presses tightly
against the wall of the air chamber 28, such that the air pushes the elastic section
272 covering the air supply channel 242 through the air supply channel 242. The elastic
valve 27 is preferably made of a rubber material for not only tightly pressing against
the wall of the air chamber 28 but also avoiding a wearing issue of hard materials.
[0027] FIGS. 4A to 4C are schematic diagrams of gas-liquid mixture as well as a corresponding
gas-liquid mixing path in an anti-leakage liquid soap valve structure of the present
invention. Referring to FIG. 4A, at an initial state, the pressure applying section
32 butts against the limiting section 221 of the outer housing 20, and the air supply
valve and the soap discharging tube 24 linked with the pressure applying section 32
stay at the initial positions. At this time, the elastic member 29 is dilated, and
a check valve at one end of the liquid soap entrance 43 is rested on and supported
by the protruding section 211. At least one gap is formed between the check valve
and the protruding section 211, so that the liquid soap 42 passes through the gap
to fill the liquid soap chamber 243. The liquid soap chamber 243 currently does not
receive any pressure, the through hole 256 of the soap discharging valve 25 is in
contact with the surrounding wall of the axle strut 254, and the liquid soap 42 is
confined within the liquid soap chamber 243. Referring to FIG. 4B, when the press
section 33 receives force from the butting element 51 and moves upwards, the pressure
applying section 32 is driven by the press section 33 to move upwards to push the
air supply valve and to compress the elastic member 29, such that the elastic member
29 is deformed and stores elasticity. At this time, the soap entering tube 212 exerts
pressure to the liquid soap chamber 243 in the soap discharging tube 24. The check
valve at one end of the liquid soap entrance 43, as affected by the positive pressure
in the liquid soap chamber 243, moves towards the liquid soap entrance 43 and butts
on the soap entering opening 11, so that the liquid soap 42 in the liquid soap chamber
243 does not enter the liquid soap container 40. Referring to FIG. 4C, when the liquid
soap chamber 243 is pressed, the liquid soap 42 is prohibited from moving towards
the liquid soap entrance 43. At this time, the liquid soap 42 can only flow towards
the liquid soap exit 244 to exert pressure to the soap discharging valve 25. As the
soap discharging valve 25 receives pressure and is affected by the pressing member,
it moves downwards to cause deformation of the elastic washer 255, such that the through
hole 256 on the elastic washer 255 expands downwards. Thus, a passage is formed between
the spacing region 253 between the butting members 252 on the pressing member and
the expanded through hole 256 so as to allow the liquid soap 42 to enter the liquid
soap exit 244 via the soap discharging valve 25 and further enter the gas-liquid mixing
chamber 311 through the liquid soap exit 244. Meanwhile, when the air supply valve
moves towards an upper end of the air chamber 28, air is only allowed to pass through
the air supply channel 242 on the supporting plate 241 since the outer ring 271 of
the elastic valve 27 presses tightly against the wall of the air chamber 28. The air
passing through the air supply channel 242 pushes the elastic section 272 covering
the air supply channel 242, and is then forwarded towards the air exit 245 to allow
the air to enter the gas-liquid mixing chamber 311 to mix with the liquid soap 42.
Further, with the foaming filter 34 disposed on the foam exit 35, the liquid soap
42 is thoroughly mixed with the air to form foamed liquid soap which is then sent
to a hand of a user via the foam exit 35.
[0028] In the present invention, to prevent the residual liquid soap 42 in the gas-liquid
mixing chamber 311 from dripping to the ground via the foam exit 35, the anti-leakage
liquid soap valve structure 100 of the present invention further provides a back-sucked
function of the liquid soap 42. FIG. 5 shows a schematic diagram of withdrawing liquid
soap 42 by an anti-leakage liquid soap valve structure according to the present invention.
When the soap discharging tube 24 is butted by the elastic member 29 to restore to
the initial position, the air supply valve is linked by the soap discharging tube
24 to push the pressure applying section 32 to restore as well until the pressure
applying section 32 butts the limiting section 221. At this time, due to the negative
pressure in the air chamber 28, air sequentially passes through the foam exit 35,
the gas-liquid mixing chamber 311 and the air supply channel 242 to be sucked back
to the air chamber 28. Meanwhile, the residual liquid soap 42 at the gas-liquid mixing
chamber 311 and the foam exit 35 is sucked back to the air chamber 28 along with the
air flow. Further, when inner and outer pressures balance, the elastic section 272
butts on the air supply channel 242 to prohibit a small amount of liquid soap 42 from
flowing into the gas-liquid mixing chamber 311.
[0029] In conclusion, through the deformation between the elastic washer and the pressing
member of the soap discharging valve, the liquid soap exit can be controlled to open
or close. Thus, with only a small force applied to the automatic press device, the
liquid soap chamber is pressurized to cause deformation of the elastic washer so that
a passage allowing the liquid soap to pass through is generated. Further, as the elastic
washer is made of a rubber material, the liquid soap is more effectively prevented
from leaking along the wall of the liquid soap exit. Moreover, the air supply valve
of the present invention allows the soap discharging tube to restore to its initial
position when being pressed by the elastic member. Meanwhile, through the negative
pressure in the air chamber, the residual liquid soap at the foam exit and the gas-liquid
mixing chamber is sucked back to the air chamber via the air supply channel, thereby
preventing the residual liquid soap from dripping to the ground and maintaining tidiness
of an operation environment.
