Description

[Technical Field]

[0001] The present invention belongs to the field of washing machines, and more particularly to an automatic loading device for laundry treatment equipment. [Background technology]

[0002] Washing machines are the most commonly used home appliances in people's daily lives. With the continuous development and advancement of technology, research and development of washing machines is increasingly focusing on improving user experience while meeting people's basic laundry requirements. More and more washing machines are equipped with automatic detergent dispensing function, which eliminates the need for users to manually add detergent when using the washing machine, making it much more convenient for users and improving the user experience.

[0003] Conventional washing machine dispensers are mainly controlled by electronic valves, utilizing the Venturi effect to dispense detergent, or by installing a small pump. The complex structure of these dispensers results in high production costs, poor performance, increased breakdowns, and increased maintenance costs. Furthermore, conventional automatic detergent dispensers generally suffer from insufficient dispensing accuracy and low reliability.

[0004] In view of this, the present invention is presented. Summary of the Invention [Problem to be solved by the invention]

[0005] The technical problem that the present invention aims to solve is to overcome the shortcomings of the prior art, and aims to provide an automatic dispensing device for clothing treatment equipment that solves the technical problem of the prior art in that clothing treatment agents cannot be accurately dispensed. [Means for solving the problem]

[0006] In order to solve the above technical problems, the basic concept of the technical solution adopted by the present invention is as follows: An automatic feeding device for a clothing processing facility, a housing having a water inlet end and a liquid outlet end disposed therein; a flexible part disposed inside the housing, dividing the inside of the housing into a storage chamber communicating with the water inlet end and a liquid absorption chamber for storing a clothing treatment agent, and the flexible part communicating with the liquid outlet end; The flexible element has a deformed portion in its natural state, and when water flows into the water inlet end, the flexible element is pressed, deforming the deformed portion, causing the flexible element to move toward the liquid absorption chamber, and the clothing treatment agent is discharged from the liquid outlet end to the outside of the liquid absorption chamber.

[0007] In the present invention, the flexible element has a deformable portion in its natural state, so that when water flows into the water inlet end, the flexible element is pressed, deforming the deformable portion, causing the flexible element to move toward the liquid absorption chamber, and the clothing treatment agent is discharged from the liquid outlet end and out of the liquid absorption chamber.This makes it possible to dispense clothing treatment agent into the washing machine even at low water pressure, thereby solving the technical problem of the prior art, where clothing treatment agent could not be dispensed accurately.

[0008] Furthermore, the flexible part further includes a cover part provided at the center of the flexible part, and the deformation part is connected to the outer periphery of the cover part.

[0009] Furthermore, the flexible part is placed on the peripheral wall of the liquid suction chamber, the inner diameter of the liquid suction chamber is larger than the inner diameter of the storage chamber, the cover part closes the communication opening between the storage chamber and the liquid suction chamber, and the deformable part is provided on the outer periphery of the communication opening.

[0010] Furthermore, the cover portion covers the connection portion between the storage chamber and the liquid absorption chamber in its natural state, and the deformable portion is connected between the cover portion and the inner peripheral wall of the liquid absorption chamber.

[0011] Furthermore, the deformation portion is folded so as to protrude in the direction of the liquid absorption chamber.

[0012] Furthermore, the aforementioned cover portion is a protruding structure that is installed in the center of the cover portion, has one end that protrudes and extends into the storage chamber, and that closes a communication opening between the storage chamber and the liquid suction chamber; The cover has an inner peripheral end connected to the protruding structure and an outer peripheral end connected to the deforming portion.

[0013] Furthermore, the automatic dispensing device further includes a protective device that is installed in the liquid absorbing chamber, connected to the flexible part, and that provides a restoring force to the flexible part to return it to its natural state when the force pressing on the flexible part is reduced.

[0014] Furthermore, the aforementioned protection device a protective sleeve, one end of which is connected to said flexible component; and an elastic element having one end connected to the protective sleeve and the other end connected to the inner wall of the liquid absorption chamber.

[0015] Furthermore, one end of the protective sleeve is a closed end, and a central portion of the closed end is provided with a convex ring toward the flexible component to form a concave portion; The other end of the protruding structure is set to protrude toward the protective sleeve to form a first protrusion, and the first protrusion is inserted into the recess.

[0016] Furthermore, the other end of the protective sleeve is an open end, and one end of the elastic element extends into the protective sleeve and is connected to the protective sleeve. [Effects of the Invention]

[0017] By adopting the above technical solutions, the present invention has the following beneficial effects compared with the prior art:

[0018] (1) In the present invention, the flexible element has a deformable portion in its natural state. When water flows into the water inlet end, the flexible element is pressed, causing the deformable portion to deform, moving the flexible element toward the liquid absorption chamber, and the clothing treatment agent is discharged from the liquid outlet end to the outside of the liquid absorption chamber. This makes it possible to dispense clothing treatment agent into the washing machine even at low water pressure, thereby solving the technical problem of the prior art, which was that clothing treatment agent could not be dispensed accurately.

[0019] (2) In the present invention, the deformable portion is provided on the outer periphery of the communication port between the storage chamber and the liquid-absorbing chamber, and is folded toward the liquid-absorbing chamber, so that the deformable portion has sufficient deformation space within the liquid-absorbing chamber when the water pressure of the water flow introduced into the water inlet end is relatively strong.

[0020] (3) One end of the protective sleeve of the present invention is closed, and the first protrusion at the other end of the protrusion structure is inserted into the recess formed by the closed end. The other end of the protective sleeve is open, and one end of the elastic element extends into the protective sleeve and is connected to the protective sleeve. This prevents the flexible part and the protective sleeve from coming into contact with each other and damaging the flexible part, thereby extending the service life of the automatic dosing device.

[0021] (4) The automatic feeding device of the clothing processing equipment of the present invention has an optimized structural design, which reduces the production cost.

[0022] Specific embodiments of the present invention will now be described in more detail with reference to the drawings. [Brief explanation of the drawings]

[0025] It should be explained that these drawings and written description are not intended to limit the scope of the inventive concept in any way, but rather to explain the inventive concept to those skilled in the art by reference to specific embodiments. DETAILED DESCRIPTION OF THE INVENTION

[0026] In order to make the objectives, technical solutions and advantages of the embodiments of the present invention clearer, the technical solutions in the embodiments will be clearly and completely described below with reference to the drawings in the embodiments of the present invention. The following embodiments are for illustrating the present invention, but are not for limiting the scope of the present invention.

[0027] It should be explained in the description of the present invention that the orientations or positional relationships indicated by the terms "upper," "lower," "front," "rear," "left," "right," "vertical," "inner," "outer," etc. are based on the orientations or positional relationships shown in the drawings, and are intended merely to facilitate the description and simplification of the present invention, and do not indicate or imply that the devices or components shown necessarily have a specific orientation or are constructed and operated in a specific orientation, and should not be understood as limiting the present invention.

[0028] As should be explained in the description of the present invention, unless otherwise clearly defined or limited, the terms "attach," "connect," and "couple" should be understood in a broad sense. For example, they may refer to fixed connection, detachable connection, or integral connection, and may also refer to mechanical connection, electrical connection, direct connection, or indirect connection via an intermediate medium. Those skilled in the art can understand the specific meaning of the above terms in the present invention according to specific circumstances.

[0029] As shown in FIGS. 1 to 6, the automatic feeding device for the clothing processing facility according to the present invention includes a housing 1 and a flexible part 2.

[0030] Inside the housing 1, a water inlet end 131 and a liquid outlet end 152 are provided.

[0031] The flexible part 2 is placed inside the housing 1. The flexible part 2 divides the interior of the housing 1 into a storage chamber 11 and a liquid-absorbing chamber 12. The storage chamber 11 communicates with the water inlet end 131, and the liquid-absorbing chamber 12 communicates with the liquid outlet end 152, and the liquid-absorbing chamber 12 is for storing a laundry treatment agent.

[0032] The flexible element 2 has a deformable portion 22 in its natural state. When water flows into the water inlet end 131, the water flow presses against the flexible element 2, deforming the deformable portion 22, and the flexible element 2 moves toward the liquid-absorbent chamber 12, causing the clothing treatment agent to be discharged from the liquid-absorbent chamber 12 through the liquid outlet end 152.

[0033] In the present invention, the flexible element 2 has a deformable portion 22 in its natural state. When water flows into the water inlet end 131, the flexible element 2 is pressed, deforming the aforementioned deformable portion 22, causing the flexible element 2 to move toward the liquid-absorbent chamber 12 and discharging the laundry treatment agent from the liquid outlet end 152 to the outside of the liquid-absorbent chamber 12. This makes it possible to dispense laundry treatment agent into the washing machine even at low water pressure, thereby solving the technical problem of the prior art in which laundry treatment agent could not be dispensed accurately.

[0034] Specifically, one end of the storage chamber 11 communicates with the water inlet end 131. The other end of the storage chamber 11 is closed by the flexible part 2.

[0035] It should be understood that, because the water inlet end 131 is directly connected to the storage chamber 11, the water flow that flows into the automatic dispensing device through the water inlet end 131 acts directly on the flexible element 2, so that even at low water pressure, the flexible element 2 moves toward the liquid absorbing chamber 12 to dispense the laundry treatment agent into the washing machine. The automatic dispensing device of the present invention can be realized by controlling the water inflow of the washing machine, which changes the automatic dispensing principle, optimizes the structural design, and reduces production costs.

[0036] A liquid inlet end 151 is further provided inside the housing 1. When the inflow of water at the water inlet end 131 stops, the deformable portion 22 returns to its natural state and moves toward the storage chamber 11, and the clothing treatment agent is sucked into the liquid-absorbing chamber 12 from the liquid inlet end 151.

[0037] Furthermore, the clothing treatment agent of the present invention includes, but is not limited to, detergents, fabric softeners, disinfectants, clothing care agents, fragrances, and the like.

[0038] Furthermore, the flexible part 2 further includes a cover part 21 provided in the center of the flexible part 2. The deformable part 22 is connected to the outer periphery of the cover part 21.

[0039] In the present invention, by providing the aforementioned cover portion 21 in the center of the aforementioned flexible part 2, the water flow flowing into the storage chamber 11 acts directly on the cover portion 21, and further, it is possible to dispense the clothing treatment agent into the washing machine even at low water pressure, thereby solving the technical problem in the prior art of not being able to dispense the clothing treatment agent accurately.

[0040] Specifically, the elastic variable of the deforming portion 22 is smaller than the elastic variable of the cover portion 21. It should be understood that when the cover portion 21 is pressed by the water flow, the elastic variable of the deforming portion 22 is smaller than the elastic variable of the cover portion 21, and therefore, at this time, the deforming portion 22 begins to elastically deform, whereby the cover portion 21 moves toward the liquid absorption chamber 12, and further the laundry treatment agent is dispensed into the washing machine.

[0041] As shown in FIG. 2, the flexible part 2 is placed on the inner peripheral wall of the liquid absorbing chamber 12 .

[0042] The inner diameter of the liquid suction chamber 12 is larger than the inner diameter of the storage chamber 11. The cover portion 21 closes the communication opening between the storage chamber 11 and the liquid suction chamber 12, and the deformation portion 22 is provided on the outer periphery of the communication opening.

[0043] The present invention solves the technical problem of the prior art, in which the clothing treatment agent could not be accurately dispensed, because the cover part 21 closes the communication opening between the storage chamber 11 and the liquid-absorbing chamber 12, the deformable part 22 is provided on the outer periphery of the communication opening, and the flexible part 2 moves toward the liquid-absorbing chamber 12 even when subjected to a water flow with relatively low water pressure.

[0044] Specifically, the outer peripheral wall of the cover portion 21 is connected to the inner peripheral wall of the deformable portion 22. More specifically, the deformable portion 22 is folded from the outer peripheral wall of the cover portion 21 toward the liquid-absorbing chamber 12.

[0045] The deformation portion 22 is first installed extending from the outer peripheral wall of the cover portion 21 in the direction of the liquid absorption chamber 12, and then bent and extended in the direction of the storage chamber 11.

[0046] In one embodiment, the inner diameter of the cover portion 21 is smaller than the inner diameter of the storage chamber 11 , and the cover portion 21 closes the communication opening between the storage chamber 11 and the liquid absorbing chamber 12 .

[0047] In another embodiment, the inner diameter of the cover portion 21 is larger than the inner diameter of the storage chamber 11 , and the cover portion 21 closes the communication opening between the storage chamber 11 and the liquid absorbing chamber 12 .

[0048] The present invention employs a feature in which the inner diameter of the cover portion 21 is larger than the inner diameter of the storage chamber 11. Specifically, in its natural state, the cover portion 21 covers the connection between the storage chamber 11 and the liquid absorbing chamber 12. The deformable portion 22 is connected between the cover portion 21 and the inner peripheral wall of the liquid absorbing chamber 12.

[0049] The present invention solves the technical problem of the prior art of being unable to accurately dispense clothing treatment agents by having the cover part 21 cover the connection between the storage chamber 11 and the liquid-absorbing chamber 12 in its natural state, thereby causing all water that flows into the storage chamber 11 to act on the cover part 21, and further by moving the cover part 21 toward the liquid-absorbing chamber 12 even when subjected to a water flow with relatively low water pressure.

[0050] Furthermore, the deformable portion 22 is connected between the cover portion 21 and the inner peripheral wall of the liquid absorption chamber 12, and while the storage chamber 11 is completely isolated from the liquid absorption chamber 12, the deformable portion 22 has sufficient deformation space within the liquid absorption chamber 12, so that when the water pressure of the water flow introduced into the water inlet end 131 is relatively strong, the deformable portion 22 has sufficient deformation space within the liquid absorption chamber 12.

[0051] Specifically, the deformable portion 22 is folded in a manner that protrudes toward the liquid absorption chamber 12 .

[0052] Preferably, said deformation portion 22 is multi-folded.

[0053] Furthermore, the cover portion 21 includes a protruding structure 211 and a buffer structure 212 .

[0054] The protruding structure 211 is disposed in the center of the cover portion 21. One end of the protruding structure 211 is disposed in a protruding manner and extends into the storage chamber 11, and the protruding structure 211 is intended to close the communication opening between the storage chamber 11 and the liquid absorbing chamber 12.

[0055] The buffer structure 212 is disposed on the exterior of the cover 21. The inner peripheral end of the buffer structure 212 is connected to the protruding structure 211, and the outer peripheral end of the buffer structure 212 is connected to the deformation portion 22.

[0056] In the present invention, one end of the protruding structure 211 is protruding and extends into the storage chamber 11, thereby blocking the communication port between the storage chamber 11 and the liquid suction chamber 12, and all of the water flowing in from the water inlet end 131 can be made to act on the protruding structure 211, and all of the kinetic energy of the water flow can be converted into elastic potential energy of the flexible part 2, making full use of energy. At the same time, energy is saved, costs are reduced, and customer demand is met.

[0057] Specifically, one side of the buffer structure 212 covers the connection portion between the storage chamber 11 and the liquid absorbing chamber 12 in a natural state.

[0058] Moreover, the flexible part 2 further includes a fixing part 23. The elastic modulus of the fixing part 23 is greater than the elastic modulus of the deformable part 22. The fixing part 23 is for fixing the flexible part 2 onto the inner wall of the first housing 13.

[0059] The housing 1 includes a first housing 13 and a second housing 14. The first housing 13 and the second housing 14 are fixedly attached with bolts.

[0060] In one embodiment, as shown in FIG. 3 , the first housing 13 and the second housing 14 are abutted to form an annular sealing groove 16, and the first housing 13 and the second housing 14 press and fix the fixing portion 23 into the annular sealing groove 16.

[0061] In the present invention, the first housing 13 and the second housing 14 press and fix the fixed portion 23 into the annular sealing groove 16, thereby ensuring a tight seal between the storage chamber 11 and the liquid suction chamber 12 and preventing the deformable portion 22 from moving inside the liquid suction chamber 12 when pressure is applied to the flexible part 2.

[0062] Specifically, the first housing 13 has a first annular connecting edge 133, and the second housing 14 has a second annular connecting edge 143. The first annular connecting edge 133 and the second annular connecting edge 143 abut against each other to form an annular sealing groove 16.

[0063] It should be noted that the volume of said annular sealing groove 16 is smaller than the volume of said fixed portion 23 .

[0064] More specifically, the inner wall of the joint between the first housing 13 and the second housing 14 is recessed outward to form a first annular connecting edge 133 and a third annular connecting edge 134 .

[0065] A second protrusion 144 is provided on the second annular connecting edge 143. There is a distance between the first annular connecting edge 133 and the second protrusion 144. The first annular connecting edge 133, the third annular connecting edge 134, the second annular connecting edge 143 and the second protrusion 144 form an annular sealing groove 16.

[0066] In another embodiment, a positioning structure is provided on the inner peripheral wall of the first housing 13, and the fixing portion 23 is installed on the positioning structure. The positioning structure fixes the fixing portion 23 inside the housing 1, and further ensures that when the deformable portion 22 of the flexible part 2 moves inside the housing 1, the storage chamber 11 and the liquid absorbing chamber 12 do not communicate with each other.

[0067] Specifically, the positioning structure includes an annular positioning rib, which is provided in a protruding manner on the inner wall of the first housing 13. One end of the fixed portion 23 abuts against the annular positioning rib. Specifically, the annular positioning rib abuts against the fixed portion 23. The fixed portion 23 is connected to the outer peripheral wall of the deformable portion 22.

[0068] In yet another embodiment, the annular sealing groove 16 is provided on the first annular connecting edge 133 and / or the second annular connecting edge 143. The first annular connecting edge 133 and / or the second annular connecting edge 143 presses and fixes the fixing portion 23 into the annular sealing groove 16.

[0069] Specifically, the annular sealing groove 16 is disposed on the first annular connecting edge 133 and / or the second annular connecting edge 143. The volume of the annular sealing groove 16 is smaller than the volume of the fixing portion 23.

[0070] In another embodiment, the first annular connecting edge 133 and the second annular connecting edge 143 press and fix the fixing portion 23 .

[0071] In addition, the first housing 13 has a first annular end 135 and a second annular end 136, a pressure relief port is provided on the second annular end 136, and the pressure relief end 132 is installed by extending from the pressure relief port toward the outside of the second annular end 136.

[0072] The annular sealing groove 16 is provided between the open end of the first housing 13 and the pressure relief port.

[0073] Specifically, the pressure relief port is located at the junction of the first annular end 135 and the second annular end 136. The pressure relief end 132 has a certain extension length.

[0074] As shown in Fig. 4, a suction pipe 141 and a supply pipe 142 are provided on the second housing 14. The suction pipe 141 is connected to the clothing treatment agent storage device and serves to suck the clothing treatment agent inside the clothing treatment agent storage device into the liquid absorbing chamber 12, and the supply pipe 142 is connected to the supply pipe 142 inside the clothing treatment device and serves to supply the clothing treatment agent inside the liquid absorbing chamber 12 into the clothing treatment device.

[0075] The first housing 13 further includes a pressure relief end 132, and the flexible part 2 covers the pressure relief end 132 in a natural state. The pressure relief end 132 communicates with the storage chamber 11. The deformable part 22 covers the pressure relief end 132 in a natural state.

[0076] The deformed portion 22 is provided on the outer periphery of the communication port, protrudes from the cover portion 21 toward the inside of the liquid absorbing chamber 12, is folded, and extends to the inner peripheral wall of the liquid absorbing chamber 12 via the pressure relief end 132.

[0077] When water flows into the water inlet end 131, the flexible element 2 is pressed, causing the aforementioned deformation portion 22 to deform, and the flexible element 2 moves toward the liquid absorption chamber 12. At the same time, the clothing treatment agent is discharged from the liquid absorption chamber 12 through the liquid outlet end 152, and the pressure relief end 132 opens, allowing the water flow to flow the discharged clothing treatment agent into the clothing treatment device.

[0078] 2 and 3, the automatic dispensing device further includes a protection device 3. The protection device 3 is installed in the liquid absorbing chamber 12, and the protection device 3 is connected to the flexible part 2. The protection device 3 is intended to provide a restoring force to the flexible part 2 for returning it to its natural state when the force pressing the flexible part 2 is reduced.

[0079] By connecting the protective device 3 to the flexible part 2, the present invention ensures that the flexible part 2 can quickly return to its natural state when the force pressing on the flexible part 2 is reduced, and also prevents the flexible part 2 from colliding with other parts and being damaged when the water pressure of the water flow introduced into the water inlet end 131 is relatively strong, thereby preventing the service life of the automatic dosing device from being affected.

[0080] Specifically, one end of the protective device 3 is disposed facing the bottom of the liquid absorbing chamber 12, and the other end of the protective device 3 is connected to the buffer structure 212 of the flexible part 2. This can be understood as meaning that when the force pressing the flexible part is reduced, the protective device 3 provides a restoring force to the flexible part 2 for returning it to its natural state, causing the flexible part 2 to move in the direction of the storage chamber 11, and the buffer structure 212 prevents the protective device 3 from colliding with the housing 1, which would damage the protective device 3 and / or the housing 1.

[0081] It should be understood that the protective device 3 does not need to be connected to the flexible part 2, and when a water flow is introduced into the water inlet end 131, the water flow will collide with the flexible part 2, and the flexible part 2 will be deformed, causing the volume inside the liquid absorption chamber 12 to change, and the laundry treatment agent will be injected into the washing machine or the laundry treatment agent will be sucked into the liquid absorption chamber 12.

[0082] When the inflow of water at the water inlet end 131 stops, the elastic element 32 returns to its original shape, pushing the protective sleeve 31 toward the storage chamber 11, and the deformed portion 22 of the flexible part 2 returns to its original position, covering the pressure relief end 132 again, increasing the volume inside the liquid absorption chamber 12 and allowing the clothing treatment agent to be sucked into the liquid absorption chamber 12.

[0083] Furthermore, the aforementioned protection device 3 comprises a protective sleeve 31 and an elastic element 32 .

[0084] One end of the aforementioned protective sleeve 31 is connected to the aforementioned flexible part 2 .

[0085] One end of the elastic element 32 is connected to the protective sleeve 31 , and the other end of the elastic element 32 is connected to the inner wall of the liquid absorption chamber 12 .

[0086] The present invention further ensures that one end of the protective sleeve 31 is connected to the flexible part 2, one end of the elastic element 32 is connected to the protective sleeve 31, and the other end of the elastic element 32 is connected to the inner wall of the liquid-absorbing chamber 12, thereby providing the flexible part 2 with a restoring force for returning it to its natural state when the force pressing against the flexible part 2 is reduced.

[0087] Furthermore, one end of the protective sleeve 31 is a closed end, and a central portion of the closed end is provided with a convex ring 313 facing the flexible part 2 to form a concave portion 311;

[0088] The other end of the protruding structure 211 is protruded toward the protective sleeve 31 to form a first protrusion 2111 , and the first protrusion 2111 is inserted into the recess 311 .

[0089] Specifically, a convex ring 313 is disposed in the center of the closed end toward the flexible component 2 to form a recess 311, and the bottom of the recess 311 is recessed toward the inside of the protective sleeve 31. The other end of the protruding structure 211 is disposed in a convex manner toward the protective sleeve 31 to form a first protrusion 2111, and the center of the first protrusion 2111 is hollow. A gap exists between the annular sidewall of the first protrusion 2111 and the inner wall of the protruding structure 211. The gap is equal to or greater than the cross-sectional length of the sidewall of the recess 311.

[0090] The first convex body 2111 is inserted into the recess 311, and the convex ring 313 is inserted into the gap existing between the annular side wall of the first convex body 2111 and the inner wall of the protruding structure 211.

[0091] More specifically, the first protrusion 2111 extends from a first position in the center of the cover part 21 toward the protective sleeve 31, then bends toward the pressure relief end 132, and then bends toward the accommodating chamber 11 again, and the extending end of the first protrusion 2111 is connected to a second position in the center of the cover part 21. There is a certain distance between the first position, the second position, and the edge of the cover part 21.

[0092] Furthermore, the other end of the protective sleeve 31 is an open end, and one end of the elastic element 32 extends into the protective sleeve 31 and is connected to the protective sleeve 31 .

[0093] Specifically, a fixing rib 312 is installed on the inner wall of the closed end of the protective sleeve 31, and one end of the elastic element 32 is fixed inside the protective sleeve via the fixing rib 312.

[0094] The housing 1 further includes a third housing 15, which is disposed inside the liquid suction chamber 12. The third housing 15 is disposed below the protective sleeve 31, and its inner diameter is larger than the outer diameter of the protective sleeve 31.

[0095] Specifically, one end of the third housing 15 is an open end, and the other end of the elastic element 32 extends to the third housing 15 of the protective sleeve 31 and is fixed on the bottom wall of the third housing 15.

[0096] The open end of the third housing 15 is disposed opposite the open end of the protective sleeve 31. When water flows into the water inlet end 131, the water flow presses against the flexible element 2, deforming the deformable portion 22 and causing the flexible element 2 to move toward the liquid-absorbent chamber 12, forcing the protective sleeve 31 to press against the elastic element 32 and compressing it. At the same time, the outer diameter of the protective sleeve 31 is smaller than the inner diameter of the third housing 15, i.e., the protective sleeve 31 moves within the third housing 15. Furthermore, because the other end of the protective sleeve 31 is closed, pressure is applied to the clothing treatment agent within the liquid-absorbent chamber 12 as the protective sleeve 31 moves toward the inside of the third housing 15, ensuring that the clothing treatment agent is expelled to the maximum extent possible from the liquid-absorbent chamber 12.

[0097] The other end of the third housing 15 is a closed end, and the liquid outlet end 152 and the liquid inlet end 151 are disposed on the closed end of the third housing 15 .

[0098] Check valves are provided on the liquid outlet end 152 and the liquid inlet end 151 so that the clothing treatment agent can flow into the liquid-absorbing chamber 12 only from the liquid inlet end 151 and can be discharged out of the liquid-absorbing chamber 12 only from the liquid outlet end 152.

[0099] In a specific embodiment, the liquid outflow end 152 of the present invention is a liquid discharge pipe, on which a one-way liquid discharge opening device is attached. The one-way liquid discharge opening device includes a valve body, a valve cover, a valve core, and a return spring, the valve body has a hollow passage therein, one end of the hollow passage in the valve body communicates with the liquid discharge pipe, a valve cover is attached to one end of the hollow passage in the valve body remote from the liquid discharge pipe, a valve hole is formed on the valve cover, one end of the valve core is attached to the valve cover so as to be able to move relative to the valve cover, and the other end is fitted into one end of the hollow passage in the valve body connected to the liquid discharge pipe, one end of the return spring contacts the valve cover, and the other end contacts the valve core.

[0100] The washing machine controls the inflow of water from the water inlet end 131, and the inflow of water presses the flexible part 2 and moves it toward the detergent chamber, causing the aforementioned deformation part 22 to deform, the volume of the detergent chamber to decrease, the pressure inside the detergent chamber to increase, and pushing the valve core, so that the valve core no longer blocks the hollow passage inside the valve body, the one-way liquid discharge opening device opens, and the clothing treatment agent is discharged from the liquid discharge pipe and dispensed.

[0101] The liquid inlet end 151 of the present invention is a liquid inlet pipe, on which a one-way liquid inlet opening device is attached. The one-way liquid inlet opening device comprises a valve body, a valve cover, a valve core, and a return spring, and has a hollow passage inside the valve body, one end of the hollow passage in the valve body communicates with the storage case and the other end communicates with the liquid inlet pipe, a valve cover is attached to one end of the hollow passage connecting the valve body and the liquid inlet pipe, a valve hole is formed on the valve cover, one end of the valve core is attached to the valve cover so as to be able to move relative to the valve cover, and the other end is fitted into one end of the hollow passage in the valve body that is connected to the liquid inlet pipe, one end of the return spring contacts the valve cover, and the other end contacts the valve core.

[0102] The washing machine controls the inflow of water from water inlet end 131, and the inflow of water presses flexible element 2, moving it toward the detergent chamber, deforming said deformable element 22, reducing the volume of the detergent chamber, increasing the pressure inside the detergent chamber, which presses against the valve core, maintaining sealing contact with the hollow passage inside the valve body, and maintaining the one-way liquid inflow opening device in a closed state. The washing machine controls the inflow of water to stop from water inlet end 131, and deformable element 22 returns to its original shape, increasing the volume of the detergent chamber, reducing the pressure, and the external pressure pushes the valve core, which no longer blocks the hollow passage inside the valve body, opening the one-way liquid inflow opening device, allowing the laundry treatment agent to flow into the liquid storage chamber.

[0103] Furthermore, in order to improve the sealing performance of the one-way fluid discharge opening device and the one-way fluid inflow opening device, a sealing ring is attached on the sealing end of the valve core.

[0104] It should be noted that in the initial state of the automatic dispensing device of the present invention, the one-way opening devices on the liquid inlet end 151 and the liquid outlet end 152 remain closed, and since the detergent chamber is filled with air during initial use, the washing machine controls the air to be discharged from the detergent chamber when water first flows in through the water inlet end 131. When the washing machine controls the water inlet end 131 to stop flowing in, the flexible element 2 returns to its natural state, and the laundry treatment agent is drawn into the liquid storage chamber. When water flows in again through the water inlet end 131, the washing machine controls the flexible element 2 to move toward the detergent chamber, and the laundry treatment agent is discharged through the liquid outlet end 152, thereby realizing automatic dispensing.

[0105] As shown in Figures 5 and 6, the automatic dispensing device further includes a dispensing case 4, and the dispensing case 4 is installed and includes a first chamber and a second chamber, the first chamber is connected to the pressure relief end 132 and the dispensing pipe 142 respectively, and the second chamber is connected to the suction pipe 141.

[0106] Specifically, the first chamber is a mixed transport channel 41, which is connected to the pressure relief end 132 and the input pipe 142, and the mixed transport channel 41 is used to mix detergent with pressure relief water and then input it into the laundry treatment equipment.

[0107] The second chamber is a detergent storage device 42 , which is installed below the mixed transport channel 41 , and is connected to the suction pipe 141 .

[0108] When water flows into the water inlet end 131, the flexible part 2 is pressed and moves toward the liquid absorption chamber 12, and the clothing treatment agent is discharged into the detergent transport channel. At the same time, the pressure relief end 132 opens, connecting the storage chamber 11 and the pressure relief transport channel 412, and the water flow causes the clothing treatment agent to flow into the clothing treatment device through the pressure relief transport channel 412.

[0109] In the present invention, the pressure relief end 132 is installed so as to be in communication with the mixed transport channel 41, so that after the detergent is added, the pressure relief water washes out the mixed transport channel 41, preventing the transport channel from being clogged with detergent remaining in the transport channel, thereby increasing the service life of the above-mentioned adding case 4 and preventing damage to clothes due to insufficient mixing of the detergent and the water flow.

[0110] Specifically, one end of the mixed transport waterway 41 is connected to the pressure relief end 132 and the input pipe 142, respectively, and the other end of the mixed transport waterway 41 is provided with an input port 43 for inputting a mixture of the laundry treatment agent and the pressure relief water into the laundry treatment device of the washing machine.

[0111] The mixed transport channel 41 includes a detergent transport channel 411 and a pressure relief transport channel 412. The detergent transport channel 411 communicates with the liquid suction chamber 12 via the input pipe 142.

[0112] One end of the pressure relief transport channel 412 communicates with the detergent transport channel 411 and the storage chamber 11, and the other end of the pressure relief transport channel 412 communicates with the inlet 43. The pressure relief transport channel 412 communicates with the storage chamber 11 via the pressure relief end 132.

[0113] The automatic dispensing device described above allows water to flow into the storage chamber 11 through the water inlet end 131, causing the flexible part 2 to be pressed and move toward the liquid absorption chamber 12, and the clothing treatment agent is discharged into the detergent transport channel 411. At the same time, the storage chamber 11 and the pressure relief transport channel 412 are opened, and the water flow causes the clothing treatment agent to flow into the clothing treatment device through the pressure relief transport channel 412.

[0114] A pressure relief port is provided at one end of the input case 4, and there is a certain distance between the pressure relief port and the side wall of the pressure relief transport channel 412. The inner diameter of the mixed transport channel 41 is larger than the inner diameter of the pressure relief end 132.

[0115] The pressure relief end 132 is inserted into the input case 4 through the pressure relief port. Specifically, the end opening of the pressure relief end 132 is inserted into the connection between the detergent transport channel 411 and the pressure relief transport channel 412. Preferably, the end opening of the pressure relief end 132 protrudes from the connection between the detergent transport channel 411 and the pressure relief transport channel 412.

[0116] In the present invention, the detergent transport channel 411 is installed so as to be in communication with the pressure relief transport channel 412, so that after the clothing treatment agent is dispensed, the pressure relief water washes out the pressure relief transport channel 412 and the detergent transport channel 411, preventing the transport channel from being clogged with detergent remaining in the transport channel, thereby increasing the service life of the above-mentioned dispenser case 4 and preventing damage to clothing due to insufficient mixing of the detergent and water flow.

[0117] Furthermore, the detergent storage device 42 is connected to the automatic dispenser via the suction pipe 141 .

[0118] In one embodiment, the detergent storage device 42 is integrally formed with the input case 4 , and the detergent storage device 42 is fixedly installed inside the input case 4 .

[0119] In another embodiment, the detergent storage device 42 is installed inside the input case 4 so as to be removable.

[0120] The means adopted by the present invention is that the detergent storage device 42 is installed so as to be retractable inside the input case 4. Specifically, an injection port 44 is installed on one side of the input case 4, and the laundry treatment agent is injected into the detergent storage device 42 through the injection port 44.

[0121] It should be noted that the automatic dispensing device of the present invention can be equipped with multiple detergent storage devices 42 for different laundry treatment agents, and the liquid storage chambers of each detergent storage device 42 can be filled with different types of laundry treatment agents, and the water flow into the corresponding detergent storage device 42 can be controlled at the corresponding time to meet the dispensing requirements of each laundry treatment agent. This ensures that the automatic dispensing device of the present invention leaves no residue during the addition of multiple different detergents and care agents, avoids cross-contamination problems between different detergents and care agents, and effectively improves the laundry cleaning effect.
