Detailed implementation manners

[0035] To make the objectives, technical solutions and advantages of the embodiments of the present invention clearer, the technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present invention. The following embodiments are used to illustrate the present invention, but are not used to limit the scope of the present invention.

[0036] In the description of the present invention, it should be noted that the orientation or positional relationship indicated by the terms "upper", "lower", "front", "rear", "left", "right", "vertical", "inner", "outer", etc. is based on the orientation or positional relationship shown in the drawings, and is only for the convenience of describing the present invention and simplifying the description, rather than indicating or implying that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore should not be construed as a limitation of the present invention.

[0037] In the description of the present invention, it should be noted that unless otherwise clearly specified and defined, the terms "installation", "connection", and "coupling" should be understood in a broad sense. For example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection or an indirect connection through an intermediate medium. For those of ordinary skill in the art, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.

[0038] As Figures 1-12 shown, in an embodiment of the present invention, a cartridge-type liquid storage box is introduced, which includes a liquid storage box body 1 with a liquid storage cavity for accommodating additives provided therein; a pipe orifice opened on the lower side of the liquid storage box body 1 to communicate the liquid storage cavity with the outside; an outer peripheral edge of the pipe orifice is connected with a liquid outlet sleeve 11 extending into the liquid storage cavity, a vertical liquid outlet flow channel is formed inside the liquid outlet sleeve 11, and a liquid extraction hole 111 communicating with the liquid outlet flow channel is opened on an outer peripheral wall of the liquid outlet sleeve 11, and the liquid extraction hole 111 is arranged close to a lower chamber wall of the liquid storage cavity.

[0039] Through the above arrangement, by arranging the liquid extraction hole 111 on a peripheral side wall of the liquid outlet sleeve 11 close to the lower chamber wall of the liquid storage cavity, the additives located between the upper end of the liquid storage sleeve and the lower chamber wall of the liquid storage cavity can be completely extracted, reducing the residual amount of additives in the liquid storage box body 1.

[0040] It should be noted that the additives are liquids such as detergents, fabric softeners, or bleaching agents that can be used for treating clothes.

[0041] In an embodiment of the present invention, a liquid collecting groove 14 is provided on the lower chamber wall of the liquid storage cavity and is recessed downward, the pipe orifice is opened at the bottom of the liquid collecting groove 14, the liquid extraction hole 111 of the liquid outlet sleeve 11 is arranged close to the bottom of the liquid collecting groove 14, and a groove wall of the liquid collecting groove 14 is arranged at a certain distance from the liquid outlet sleeve 11; preferably, a lower hole wall of the liquid extraction hole 111 is flush with the bottom of the liquid collecting groove 14.

[0042] Through the above arrangement, the additives flow into the liquid collecting groove 14 through an interval space between the groove wall of the liquid collecting groove 14 and the liquid outlet sleeve 11, so that the additives converge in the liquid collecting groove 14, further reducing the residual amount of additives in the liquid storage cavity.

[0043] In an embodiment of the present invention, the lower chamber wall of the liquid storage cavity is inclined downward from the outer periphery to the pipe orifice; so as to cause the additives to converge into the liquid collecting groove 14.

[0044] In an embodiment of the present invention, a mounting seat 113 protruding from the wall surface is provided on the outer peripheral wall of the liquid outlet sleeve 11; a liquid level probe 6 is provided in the liquid outlet sleeve 11. The liquid level probe 6 at least includes a detection portion 62 protruding from the upper surface of the mounting seat 113. The lower end of the detection portion 62 is located at the same height position as the upper side hole wall of the liquid extraction hole 111; so that when the liquid level is higher than the upper side hole wall of the liquid extraction hole 111, the detection portion 62 can accurately detect the liquid level height.

[0045] In an embodiment of the present invention, the detection portion 62 is a vertically arranged strip-shaped electrode plate. At least two liquid level probes 6 are provided, and the liquid level probes 6 are respectively arranged at a certain distance from each other. By applying electricity to the detection portion 62, the electric potential between the two detection portions 62 will change according to the change of the liquid level of the additive, so that the liquid level detection circuit can accurately judge the liquid level in the liquid storage box body 1 according to the change of the electric potential.

[0046] In an embodiment of the present invention, the top of the liquid collection tank 14 is located at the same height position as the lower end of the detection portion 62; the detection portion 62 is located above the liquid collection tank 14, and only the additive on the lower side chamber wall of the liquid storage chamber is detected, so that the detection portion 62 detects a region with a substantially equal cross-section, and the detection value is accurate and the credibility is high; more importantly, when the detection portion 62 just fails to detect the liquid level, it can be confirmed that the remaining amount of the additive in the liquid storage box body 1 is equal to the volume of the liquid collection tank 14. Since the volume of the liquid collection tank 14 is small, the dosing device can judge whether the remaining additive meets the amount required for the current washing program, and remind the user through the washing machine, thereby improving the judgment accuracy of the remaining amount of the additive in the liquid storage box body 1.

[0047] In an embodiment of the present invention, the tank wall of the liquid collection tank 14 is inclined inward from top to bottom, and the side wall at the lower end of the detection portion 62 is arranged at a certain distance from the tank wall of the liquid collection tank 14; to increase the passing area of the top of the liquid receiving tank and make the additive flow into the liquid collection tank 14 more smoothly; more importantly, by setting the inclined top, the distance between the top and the lower end of the detection portion 62 is increased, so that when the liquid level of the additive is lower than the lower end of the detection portion 62, it is possible to prevent the additive from forming an annular liquid film around the outer periphery of the liquid outlet sleeve 11 in the space between the top and the lower end of the detection portion 62, resulting in the conduction of the detection portion 62 of the liquid level probe 6 and the situation that the dosing device does not alarm when the liquid is lacking.

[0048] In an embodiment of the present invention, at least two liquid extraction holes 111 are arranged on the liquid outlet sleeve 11 along the circumferential direction, and liquid level probes 6 are respectively arranged on the gaps between the two liquid extraction holes 111 of the liquid outlet sleeve 11; preferably, the two liquid extraction holes 111 and the two liquid level probes 6 are equidistantly distributed in the circumferential direction of the liquid storage sleeve.

[0049] With the above settings, by providing a plurality of liquid extraction holes 111 located in different radial directions of the liquid outlet sleeve 11 to suck the additives at various positions in the liquid collection tank 14, the residual amount of the additives in the liquid storage box body 1 is further reduced. Additionally, when the dosing device sucks the additives and the liquid level of the additives is relatively low, the liquid level height in the local area above the liquid extraction holes 111 is lower than that in other areas. By arranging the liquid level probe 6 at the position between the liquid extraction holes 111, the accuracy of the liquid level probe 6 in judging the liquid level height of the additives is improved.

[0050] In an embodiment of the present invention, a relief groove 112 recessed inward is provided on the outer peripheral wall of the liquid outlet sleeve 11, and the liquid extraction holes 111 are opened at the bottom of the relief groove 112. The bottom of the relief groove 112 is arranged at a certain distance from the lower side wall of the liquid collection tank 14; the liquid inlet end of the liquid extraction hole 111 is arranged at a certain distance from the tank wall of the liquid collection tank 14. When there is less additive, it is prevented that a liquid film is formed between the tank wall and the liquid inlet end of the liquid extraction hole 111, resulting in the abnormal outflow of the additive.

[0051] In an embodiment of the present invention, a check valve 12 is arranged in the liquid outlet sleeve 11. The check valve 12 includes a valve core 121 slidably arranged in the vertical direction. The lower end of the valve core 121 is in sealing contact with an annular sealing projection 114 provided on the inner peripheral wall of the liquid outlet sleeve 11; a limiting projection 115 protruding from the flow channel wall is provided in the liquid outlet flow channel, and a radially protruding abutting portion 122 is provided on the peripheral side wall of the valve core 121. The lower surface of the abutting portion 122 abuts against the upper surface of the limiting projection 115; the lower side hole wall of the liquid extraction hole 111 is flush with the abutting wall.

[0052] With the above settings, the lower side hole wall of the liquid extraction hole 111 is arranged close to the check valve 12, so that the structural distribution in the liquid outlet sleeve 11 is more compact, the length of the lower end of the liquid outlet sleeve 11 protruding from the lower surface of the liquid storage box body 1 is reduced, and the overall size of the dosing device is reduced.

[0053] In an embodiment of the present invention, an annular sealing projection 114 protruding from the wall surface is provided on the inner peripheral wall of the liquid outlet sleeve 11, and the lower surface of the valve core 121 of the check valve 12 is in sealing contact with the upper surface of the annular sealing projection 114; preferably, the limiting projection 115 is an annular projection structure; further preferably, the lower side of the limiting projection 115 and the upper side of the sealing projection 114 are integrally arranged, and the projection height of the limiting projection 115 is less than the projection height of the sealing projection 114, so that the limiting projection 115 and the sealing projection 114 cooperate to form an annular structure with a gradually decreasing inner diameter along the flow direction of the liquid outlet flow channel.

[0054] In an embodiment of the present invention, a sealing wall is provided at the upper end of the liquid outlet sleeve 11 to form the upper end face of the liquid outlet sleeve 11; the check valve 12 further includes a valve stem 123 extending vertically. The lower end of the valve stem 123 is integrally connected to the valve core 121. A vertical through hole is provided on the sealing wall, and the valve stem 123 is slidably arranged in the through hole. The hole wall of the through hole is in close contact with the valve stem 123; to limit the valve stem 123 in the horizontal direction through the through hole of the sealing wall, so that the valve stem 123 and the valve core 121 are always slidably arranged in the vertical direction.

[0055] In an embodiment of the present invention, an elastic member 124 is further provided in the liquid outlet sleeve 11. The upper end and the lower end of the elastic member 124 are respectively in close contact with the sealing wall and the valve core 121; preferably, the elastic member 124 is a spiral structure coaxial with the valve stem 123; the valve core 121 is abutted against the sealing protrusion 114 through the elastic member 124, so that the valve core 121 is kept in a normally closed state; under the push of an external force, the valve core 121 and the valve stem 123 move upward and compress the elastic member 124. After the external force is removed, the elastic member 124 pushes the valve core 121 back to its original position.

[0056] In an embodiment of the present invention, a grille extending towards the opposite side wall is provided on at least one side wall of the liquid extraction hole 111 to divide the liquid extraction hole 111 into a plurality of small holes.

[0057] During the gradual reduction of the additive in the liquid storage box body 1, due to factors such as long-term standing, temperature rise, or oxidation by air of the additive, the additive is prone to caking. If the caked additive enters the flow channel of the dispensing device through the liquid extraction hole 111, it will adhere to the flow channel wall, resulting in blockage of the flow channel and affecting the normal operation of the dispensing device; the present invention divides the liquid extraction hole 111 into a plurality of small holes through the grille to filter the additive and prevent the caked additive from entering the liquid outlet flow channel to avoid the occurrence of the above problems.

[0058] In an embodiment of the present invention, each grille extends vertically and is horizontally arranged on the hole wall of the liquid extraction hole 111 to divide the liquid extraction hole 111 into strip-shaped small holes arranged circumferentially along the liquid outlet sleeve 11, so as to increase the vertical length of each small hole and prevent the additive from forming a liquid film on the passing surface of the small hole, thereby hindering the flow of the additive.

[0059] As shown in the figure, in an embodiment of the present invention, a dispensing device is also introduced, which internally has a vertically extending liquid suction pipe; characterized in that a cartridge-type liquid storage box as described above is provided in the dispensing device, and the liquid outlet sleeve 11 of the liquid storage box is sleeved on the upper end of the liquid suction pipe, so that the liquid storage cavity is communicated with the liquid extraction conduit. The additive flows out through the vertical liquid outlet pipe

[0060] In an embodiment of the present invention, the dispensing device further includes an installation groove 3 for carrying the liquid storage box body 1. A push rod assembly 2 is provided at the bottom of the groove. The liquid suction channel 21 inside the push rod assembly 2 is communicated with the inside of the liquid storage box body 1 through the bottle mouth of the liquid storage box body 1. A conductive probe 7 is provided at the bottom of the installation groove 3. The fixed end is electrically connected to the liquid level detection circuit of the dispensing device. The lower end of the liquid level probe 6 extends to the outside of the liquid storage box body 1 through the installation channel of the liquid outlet sleeve 11, and the extended end of the conductive probe 7 is arranged in contact with the liquid level probe 6.

[0061] Through the above arrangement, by providing a liquid level probe 6 that can penetrate from the inside in the liquid storage box body 1, and realizing the electrical connection between the liquid level probe 6 and the liquid level detection circuit by the way that the conductive probe 7 is in contact with the liquid level probe 6, when replacing the liquid storage box body 1, the wear of the liquid level detection assembly composed of the liquid level probe 6 and the conductive probe 7 is greatly reduced, the durability of the liquid level detection assembly is improved, and the overall service life of the dispensing device is improved.

[0062] In an embodiment of the present invention, the liquid storage box body 1 is provided with a downwardly protruding tubular bottle mouth on the outer periphery of the pipe orifice. The lower end of the liquid outlet sleeve 11 is integrally connected with an end cover portion 13. The end cover portion 13 is bent radially outward from the lower end of the liquid outlet sleeve 11 to wrap the lower end face and at least part of the outer peripheral face of the bottle mouth. The lower end of the liquid level probe 6 extends along the outer side face of the end cover portion 13 and is in contact with the conductive probe 7.

[0063] In an embodiment of the present invention, the extended end of the liquid level probe 6 is provided with a flanging 61 that bends and extends radially outward. The flanging 61 is arranged in contact with the conductive probe 7. By providing the flanging 61, the surface area of the liquid level probe 6 exposed outside the liquid storage box body 1 is increased, making it easier for the conductive probe 7 to be electrically connected to the corresponding liquid level probe 6, and preventing the situation that the connection between the conductive probe 7 and the liquid level probe 6 is unstable when the installation position of the liquid storage box body 1 deviates slightly.

[0064] In an embodiment of the present invention, the flanging 61 includes a first bending portion 611 that bends and extends radially outward, and a second bending portion 612 that bends upward from the first bending portion 611. The second bending portion 612 is arranged in contact with the outer peripheral face end face of the end cover portion 13, and the conductive probe 7 is in contact with the second bending portion 612. Preferably, the extended end of the conductive probe 7 is located in the radial direction of the end cover portion 13.

[0065] Through the above arrangement, through two bends, the flanging 61 is arranged on the outer peripheral face of the end cover portion 13, and the extended end of the conductive probe 7 can be arranged in the radial direction of the end cover portion 13. While facilitating the contact between the conductive probe 7 and the flanging 61, when the end cover portion 13 is too close to the bottom of the installation groove 3 during the installation process, it can prevent the end face of the end cover portion 13 far from the liquid outlet end from squeezing the conductive probe 7, resulting in excessive deformation of the conductive probe 7.

[0066] In an embodiment of the present invention, the first bending portion 611 is disposed in contact with the end face of the end cover portion 13 away from one end of the liquid storage box body 1.

[0067] In an embodiment of the present invention, a first groove recessed inward is provided at the position where the end cover portion 13 is in contact with the first bending portion 611. One side of the first bending portion 611 is disposed in contact with the lower side of the first groove, and the opposite side surface is flush with the end face of the end cover portion 13.

[0068] In an embodiment of the present invention, a second fixing hole 614 is formed in the first bending portion 611, a third fixing hole is correspondingly formed in the lower side of the first groove, and a second fixing member is disposed in the dispensing device. The second fixing member is inserted into the third fixing hole through the second fixing hole 614 so that the electrode element is fixed on the end cover portion 13.

[0069] In an embodiment of the present invention, a second groove 131 recessed inward is provided at the position where the outer peripheral surface of the end cover portion 13 is in contact with the second bending portion 612. One side of the second bending portion 612 is disposed in contact with the lower side of the second groove 131, and the opposite side is flush with the outer peripheral surface of the end cover portion 13.

[0070] In an embodiment of the present invention, a first fixing hole 132 recessed inward is provided in the lower side of the second groove 131. The extending end of the second bending portion 612 is provided with a third bending portion 613 bent and extending in a direction close to the end cover portion 13, and the third bending portion 613 is correspondingly inserted into the first fixing hole 132.

[0071] In an embodiment of the present invention, the extending ends of the respective conductive probes 7 are each provided with a fourth bending portion 71 bent and extending toward the liquid level probe 6. The extending end of the fourth bending portion 71 is disposed in contact with the motor unit. By providing the bending structure formed by the fourth bending portion 71, when the liquid level probe 6 presses the conductive probe 7, the bending structure can absorb part of the deformation amount, preventing the overall irreversible deformation of the conductive probe 7 due to excessive bending, thereby improving the structural strength of the conductive probe 7.

[0072] In an embodiment of the present invention, the fourth bending portion 71 is disposed in contact with the second bending portion 612.

[0073] In an embodiment of the present invention, the extending end of the conductive probe 7 is located outside the radial direction of the end cover portion 13, and the extending end of the fourth bending needle portion extends downward from the conductive probe 7 to the end cover portion 13, so as to reduce the damage caused by rubbing between the liquid level probe 6 and the fourth bending portion 71 and improve the service life of the conductive probe 7.

[0074] In an embodiment of the present invention, a fifth bending portion 72 extending radially outward is provided on the extending end of each fourth bending portion 71; preferably, the fifth bending portion 72 is bent in an arc shape by the fourth bending portion 71; the liquid level probe 6 is fitted with the bending connection between the fourth bending portion 71 and the fifth bending portion 72, thereby further reducing the damage to the liquid level probe 6 and the conductive probe 7 when the liquid storage box body 1 is assembled.

[0075] In the embodiment of the present invention, the extending end of the fifth bending portion 72 is arranged at a certain distance from the conductive probe 7 to provide space for the fourth bending portion 71 and the fifth bending portion 72 to be compressed and deformed.

[0076] In the embodiment of the present invention, the conductive probe 7, the fourth bending portion 71 and the fifth bending portion 72 are integrally formed.

[0077] like Figures 8-11 As shown, in the embodiment of the present invention, a plug hole 31 is provided at the bottom of the installation slot 3 , and a plug-in portion 73 is provided on the conductive probe 7 , and the plug-in portion 73 is detachably plugged into the plug hole 31 .

[0078] Through the above arrangement, by detachably setting the conductive probe 7 on the mounting groove 3, the conductive probe 7 can be replaced or removed for thorough cleaning to prevent the conductive probe 7 from being deformed or contaminated by additives dripping from the liquid storage box body 1, resulting in inaccurate detection.

[0079] In an embodiment of the present invention, the plug-in portion 73 is a sheet-like structure, and the corresponding socket 31 is set as a long strip structure. Through a shape-matched plug-in method, the socket 31 limits the plug-in portion 73 circumferentially to prevent the conductive probe 7 from rotating and shifting in the socket 31, resulting in poor contact between the conductive probe 7 and the liquid level probe 6.

[0080] In the embodiment of the present invention, the socket 31 passes through the bottom wall 32 of the bottom of the installation groove 3, and the extending end of the plug-in portion 73 protrudes from the bottom wall 32. The surrounding side walls of the extending end of the plug-in portion 73 are provided with deformable snap-fit ​​structures 731731 of the protruding wall surface, and the snap-fit ​​structure 731 abuts against the bottom wall 32; when the plug-in portion 73 passes through the bottom wall 32, the plug-in portion 73 is limited by the snap-fit ​​structure 731, so as to prevent the plug-in portion 73 from being driven out of the socket 31 by friction when the liquid storage box body 1 is pulled out, thereby improving the installation stability of the plug-in portion 73.

[0081] In an embodiment of the present invention, the engaging structure 731 is a rib plate that extends obliquely away from the insertion portion 73 from the extended end of the insertion portion 73 towards the installation groove 3, and the extended end of the engaging structure 731 is disposed at a certain distance from the insertion portion 73. When the engaging portion passes through the insertion hole 31 of the insertion portion 73, the obliquely extending engaging structure 731 is compressed and deformed towards the spaced space between it and the insertion portion 73. While ensuring the stability of the engaging structure 731 in limiting the insertion portion 73, the insertion process of the insertion portion 73 is made smoother. At the same time, the engaging structure 731 is not easily deformed irreversibly due to excessive deformation during the insertion process, improving the durability of the engaging structure 731.

[0082] In an embodiment of the present invention, a receiving opening is formed on the peripheral side wall of the insertion portion 73, and when the engaging structure 731 is compressed and deformed towards the insertion portion 73, the engaging structure 731 is located within the space in the receiving opening.

[0083] In an embodiment of the present invention, a recessed third pressing pattern 33 is provided on the surface of the bottom wall 32 on the side away from the liquid storage box body 1, the insertion hole 31 is correspondingly opened below the third pressing pattern 33, the side wall of the third pressing pattern 33 is spaced from the engaging structure 731, and the engaging structure 731 abuts against the lower side of the third pressing pattern 33. A space for accommodating the engaging structure 731 is formed by the third pressing pattern 33. At the same time, the third pressing pattern 33 can strengthen the structural strength of the bottom wall 32, preventing the bottom plate from deforming due to excessive force when the engaging structure 731 of the conductive probe 7 presses the bottom plate towards the liquid storage box body 1.

[0084] In an embodiment of the present invention, a supporting portion 34 is provided on the side of the bottom wall 32 away from the liquid storage box body 1; an engaging structure 731 is provided on one side of the insertion portion 73, and the opposite side abuts against the supporting portion 34.

[0085] In an embodiment of the present invention, the supporting portion 34 abuts at least against the position on the opposite side of the insertion portion 73 where it is connected to the engaging structure 731.

[0086] In an embodiment of the present invention, the supporting portion 34 is at least partially disposed within the third pressing pattern 33; preferably, the supporting portion 34 is integrally formed with the third pressing pattern 33.

[0087] In an embodiment of the present invention, a fourth fixing hole 732 is formed on the extended end of the insertion portion 73, a corresponding fifth fixing hole 341 is formed on the supporting portion 34, and a second fixing member is disposed within the dispensing device, and the second fixing member passes through the third fixing hole and is connected to the fifth fixing hole 341.

[0088] In an embodiment of the present invention, the supporting portion 34 at least partially protrudes from the surface of the bottom wall 32 side away from the liquid storage box body 1, and the fifth fixing hole 341 is arranged on this part of the supporting portion 34; so that the second fixing member and the locking structure 731 are staggered at a certain distance to prevent the distance between the two components from being too small to affect the installation.

[0089] In an embodiment of the present invention, positioning protrusions 74 with protruding surfaces are respectively provided on two pairs of side surfaces of the conductive probe 7, and each positioning protrusion 74 is respectively abutted against the bottom of the mounting groove 3; so as to limit the conductive probe 7 and prevent the conductive probe 7 from being inserted into the socket 31 too long, resulting in the conductive probe 7 being unable to contact the liquid level probe 6.

[0090] In the embodiment of the present invention, a receiving groove recessed inwardly is provided at the position where the bottom of the installation groove 3 abuts against each positioning protrusion 74; each positioning protrusion 74 is respectively inserted into the corresponding receiving groove one by one, and each positioning protrusion 74 is respectively flush with the bottom of the installation groove 3.

[0091] like Figures 1-12 As shown, in an embodiment of the present invention, the dispensing device further includes a partition plate 5, which divides the internal space of the dispensing device into a storage chamber for accommodating the liquid storage box body 1 and an equipment chamber for accommodating the liquid collecting channel 4; each mounting groove 3 is detachably arranged on the partition plate 5.

[0092] Through the above arrangement, by detachably arranging the mounting slot 3 on the partition plate 5, when the user removes the conductive probe 7, the user can first take out the mounting slot 3 and then remove the conductive probe 7 from the mounting slot 3, so that the user can clean, repair or replace the conductive probe 7 conveniently.

[0093] In the embodiment of the present invention, a liquid suction channel 21 is formed in the liquid suction pipe of the delivery device, and a push rod assembly 2 is also provided in the liquid suction pipe. The push rod assembly 2 pushes the check valve 12 to separate from the inner wall of the liquid outlet flow channel, so that the liquid outlet flow channel is connected to the liquid suction channel 21.

[0094] In the embodiment of the present invention, the liquid storage box body 1 is provided with a liquid outlet channel, which is connected to the inside of the liquid storage box body 1. The detergent in the liquid storage box body 1 flows into the dispenser through the liquid outlet channel to dispense the detergent.

[0095] In the embodiment of the present invention, the push rod assembly 2 has a liquid suction channel 21 inside, and the liquid suction channel 21 is connected with the liquid outlet channel. The push rod assembly 2 pushes the valve core 121 of the check valve 12 to move, so that the check valve 12 and the sealing protrusion 114 of the liquid outlet channel are arranged at a certain distance, thereby making the liquid outlet channel communicate with the liquid suction channel 21, so that the detergent flows into the liquid suction channel 21 through the gap between the valve core 121 and the sealing protrusion 114.

[0096] In an embodiment of the present invention, the installation groove 3 is arranged outside the push rod assembly 2 and is used to collect the liquid leaked from the liquid outlet channel when the push rod assembly 2 is separated from the check valve 12, so as to avoid the dripping or leakage of the detergent.

[0097] In an embodiment of the present invention, during the installation process of the liquid storage box body 1, the liquid storage box body 1 gradually moves downward, and the push rod assembly 2 extends into the liquid storage box body 1, pushing the check valve 12 in the liquid outlet channel to separate from the inner wall of the liquid outlet channel, so that the liquid outlet channel is communicated with the liquid suction channel 21. Furthermore, the liquid in the liquid storage box body 1 flows into the liquid suction channel 21 for the delivery of the detergent.

[0098] In an embodiment of the present invention, during the pulling-out process of the liquid storage box body 1, the liquid storage box body 1 gradually moves upward, and the push rod assembly 2 is gradually separated from the check valve 12, so that the check valve 12 is sealed with the inner wall of the liquid outlet channel, and the liquid outlet channel is not communicated with the liquid suction channel 21, preventing the liquid in the liquid storage box body 1 from flowing out.

[0099] In an embodiment of the present invention, by setting the check valve 12 to be sealed with the inner wall of the liquid outlet channel, liquid leakage or backflow is prevented; by setting the push rod assembly 2 to push the check valve 12 to separate from the inner wall of the liquid outlet channel, the liquid outlet channel is communicated with the liquid suction channel 21, realizing the flow of the liquid in the liquid storage box body 1 into the liquid suction channel 21 for delivery; by setting the installation groove 3 to collect the liquid leaked from the liquid outlet channel when the push rod assembly 2 is separated from the check valve 12, further avoiding liquid leakage or dripping, preventing the failure of the washing equipment, effectively ensuring the use safety of the dispenser, and thus improving the user experience.

[0100] In an embodiment of the present invention, the other end of the push rod assembly 2 extends outside the liquid outlet channel.

[0101] In an embodiment of the present invention, the end of the push rod assembly 2 far from the check valve 12 can extend outside the liquid outlet channel, providing an installation position for the fixation of the installation groove 3.

[0102] In an embodiment of the present invention, the inner wall of the liquid outlet channel close to the push rod assembly 2 is set as an inwardly concave convex-shaped structure. The part of the push rod assembly 2 extending into the liquid outlet channel is set as an outwardly convex convex-shaped structure, and convex ribs are arranged outside the push rod assembly 2, and sealing rings are arranged between the convex ribs for increasing the seal between the push rod assembly 2 and the inner wall of the liquid outlet channel.

[0103] In an embodiment of the present invention, the installation groove 3 is formed by extending along a direction perpendicular to the push rod assembly 2 from the outer peripheral wall of the push rod assembly 2, and then extending close to the liquid storage box body 1 along a direction parallel to the push rod assembly 2 to form a cavity.

[0104] Specifically, the installation groove 3 provided outside the push rod assembly 2 can form a concave cavity structure. The installation groove 3 extends a certain distance along the direction perpendicular to the push rod assembly 2 from the outer peripheral wall of the end of the push rod assembly 2 extending out of the liquid outlet channel, and then extends a certain distance close to the liquid storage box body 1 along the direction parallel to the push rod assembly 2, forming a concave cavity structure with a certain depth.

[0105] Through the above settings, when the liquid storage box body 1 is pulled out from the push rod assembly 2, the valve core 121 returns to its position under the pushing force of the elastic member 124 and seals with the annular sealing protrusion 114 of the liquid outlet channel. However, during the return process, some liquid may still drip from the gap. The concave cavity-shaped installation groove 3 is provided to collect the liquid leaked from the liquid outlet channel when the push rod assembly 2 is separated from the check valve 12, thereby further preventing the liquid from dripping into the device and avoiding device failure.

[0106] In an embodiment of the present invention, the installation groove 3 is a concave cavity structure, and the inner peripheral wall on the lower side of the installation groove 3 is connected to the outer peripheral wall of the push rod assembly 2, for collecting the liquid leaked from the liquid outlet channel when the push rod assembly 2 is separated from the check valve 12, and preventing the liquid from dripping into the device.

[0107] In an embodiment of the present invention, the push rod assembly 2 includes a first push rod 22 and a second push rod 23, and one end of the first push rod 22 extends into the liquid outlet channel.

[0108] It should be noted that the first push rod 22 is a part of the push rod assembly 2 close to the check valve 12; the second push rod 23 is the other part of the push rod assembly 2 away from the check valve 12 and extending out of the liquid outlet channel.

[0109] In an embodiment of the present invention, one end of the first push rod 22 close to the check valve 12 can extend into the liquid outlet channel. The first push rod 22 pushes the check valve 12 to separate from the inner wall of the liquid outlet channel, realizing the communication between the liquid outlet channel and the liquid suction channel 2121.

[0110] In an embodiment of the present invention, the liquid suction channel 21 includes a first liquid suction channel 221 provided inside the first push rod 22, and a second liquid suction channel 231 provided inside the second push rod 23.

[0111] In an embodiment of the present invention, a first liquid suction channel 221 is provided inside the first push rod 22, a second liquid suction channel 231 is provided inside the second push rod 23, and the first liquid suction channel 221 communicates with the second liquid suction channel 231.

[0112] In an embodiment of the present invention, the liquid suction port 222 of the first liquid suction channel 221 communicates with the liquid outlet channel.

[0113] In an embodiment of the present invention, a liquid suction port 222 is provided at one end of the first liquid suction channel 221 close to the liquid outlet channel. After the first push rod 22 pushes the check valve 12 to separate from the inner wall of the liquid outlet channel, the liquid suction port 222 of the first liquid suction channel 221 communicates with the liquid outlet channel, so that the liquid in the liquid outlet channel flows through the liquid suction port 222 to the first liquid suction channel 221 for liquid dispensing.

[0114] In an embodiment of the present invention, the liquid suction port 222 is provided on one side of the top of the first push rod 22.

[0115] In an embodiment of the present invention, the liquid suction port 222 of the first liquid suction channel 221 is provided on one side of the top of the first push rod 22 close to the liquid outlet channel, so that when the check valve 12 separates from the inner wall of the liquid outlet channel, it is convenient for the liquid to flow into the first liquid suction channel 221.

[0116] In an embodiment of the present invention, the cross-sectional area of the first liquid suction channel 221 is smaller than the cross-sectional area of the second liquid suction channel 231.

[0117] In an embodiment of the present invention, the first liquid suction channel 221 communicates with the second liquid suction channel 231. The cross-sectional area of the first liquid suction channel 221 is smaller than the cross-sectional area of the second liquid suction channel 231, that is, the volume of the first liquid suction channel 221 is smaller than the volume of the second liquid suction channel 231. Due to the smaller volume of the first liquid suction channel 221, the liquid flowing in from the liquid outlet channel is squeezed by the inner wall of the first liquid suction channel 221, thereby accelerating the liquid flow rate. And the volume of the second liquid suction channel 231 is larger, so that a larger volume of liquid can be temporarily stored in the second liquid suction channel 231, slowing down the liquid flow, which is more conducive to the dispenser to achieve quantitative dispensing.

[0118] In an embodiment of the present invention, the push rod assembly 2 further includes a liquid leakage prevention mechanism 24.

[0119] In an embodiment of the present invention, the push rod assembly 2 and the installation groove 3 can be integrally formed. When the installation groove 3 collects a large amount of leaked liquid and it is necessary to disassemble the push rod assembly 2 to clean the installation groove 3. At this time, after the push rod assembly 2 is disassembled, the liquid leakage prevention mechanism 24 is used to prevent the liquid from leaking from the liquid suction channel 21.

[0120] In an embodiment of the present invention, the liquid leakage prevention mechanism 24 is disposed in the second liquid suction channel 231 and is used to open or close the liquid outlet 232 of the second liquid suction channel 231.

[0121] In an embodiment of the present invention, the liquid leakage prevention mechanism 24 is disposed in the second liquid suction channel 231 and is disposed near the liquid outlet 232 of the second liquid suction channel 231. When the push rod assembly 2 is pulled out, the liquid leakage prevention mechanism 24 is used to close the liquid outlet 232 of the second liquid suction channel 231 to prevent the liquid in the second liquid suction channel 231 from leaking. When the push rod assembly 2 is inserted, the liquid leakage prevention mechanism 24 is pushed to open the liquid outlet 232 of the second liquid suction channel 231, so that the liquid flows into the dispenser through the liquid outlet 232 to realize the liquid dispensing process.

[0122] In an embodiment of the present invention, the liquid leakage prevention mechanism 24 is a ball valve. Specifically, the liquid leakage prevention mechanism 24 can be set as a ball valve. The ball valve is disposed in the second liquid suction channel 231, and the ball valve is sealed with the inner wall of the liquid outlet 232 to prevent the liquid in the second liquid suction channel 231 from leaking. More specifically, when the push rod assembly 2 is inserted, the ball valve is separated from the inner wall of the liquid outlet 232, so that the liquid in the second liquid suction channel 231 flows into the dispenser through the liquid outlet 232. When the push rod assembly 2 is pulled out, the ball valve is sealed with the inner wall of the liquid outlet 232 to close the liquid outlet 232 and prevent the liquid from leaking.

[0123] In an embodiment of the present invention, the diameter of the ball valve is smaller than the inner diameter of the second liquid suction channel 231 and larger than the inner diameter of the first liquid suction channel 221.

[0124] In an embodiment of the present invention, the diameter of the ball valve is smaller than the inner diameter of the second liquid suction channel 231 and larger than the inner diameter of the first liquid suction channel 221, that is, the diameter of the ball valve is smaller than the diameter of the inner peripheral wall of the second liquid suction channel 231 but larger than the diameter of the inner peripheral wall of the first liquid suction channel 221. With such a setting, a certain gap is reserved between the ball valve and the inner peripheral wall of the second liquid suction channel 231, so that the ball valve can move freely to facilitate the sealing or separation of the ball valve from the inner wall of the liquid outlet 232, thereby realizing the closing or opening of the liquid outlet 232.

[0125] In an embodiment of the present invention, the dispenser further includes a liquid collecting channel 4. The liquid collecting channel 4 is communicated with the second liquid suction channel 231, and the liquid flows into the dispenser through the liquid collecting channel 4.

[0126] In an embodiment of the present invention, one end of the second push rod 23 is disposed inside the liquid collecting channel 4.

[0127] In an embodiment of the present invention, one end of the second push rod 23 close to the liquid collecting channel 4 extends into the liquid collecting channel 4, so that the liquid in the second liquid suction channel 231 flows into the communicated liquid collecting channel 4.

[0128] In an embodiment of the present invention, a push rod 41 is provided in the liquid collecting channel 4. The push rod 41 extends into the liquid outlet 232 of the second liquid suction channel 231, and pushes the liquid leakage prevention mechanism 24 to open the liquid outlet 232.

[0129] In an embodiment of the present invention, a liquid leakage prevention mechanism 24 is provided in the second liquid suction channel 231. The liquid leakage prevention mechanism 24 is sealed with the inner wall of the liquid outlet 232. One end of the liquid collecting channel 4 close to the liquid outlet 232 is provided with a push rod 41, and the push rod 41 can extend into the liquid outlet 232 of the second liquid suction channel 231 to abut against the liquid leakage prevention mechanism 24.

[0130] In a specific implementation process, the push rod assembly 2 is inserted into the liquid collecting channel 4. The push rod 41 pushes the liquid leakage prevention mechanism 24 to separate from the inner wall of the liquid outlet 232, so as to open the liquid outlet 232, making the second liquid suction channel 231 communicate with the liquid collecting channel 4. Alternatively, when the push rod assembly 2 is pulled out from the liquid collecting channel 4, the push rod 41 separates from the liquid leakage prevention mechanism 24, and the liquid leakage prevention mechanism 24 seals the inner wall of the liquid outlet 232 to close the liquid outlet 232.

[0131] In an embodiment of the present invention, the liquid leakage prevention mechanism 24 can adopt a ball valve. The movement process of the ball valve and the push rod 41 can refer to the description of the liquid leakage prevention mechanism 24 and the push rod 41 above, and will not be elaborated here.

[0132] In an embodiment of the present invention, the dispenser further includes a partition plate 5. Specifically, the liquid storage box body 1 is arranged on the partition plate 5, and the partition plate 5 is used to support the liquid storage box body 1 to keep the liquid storage box body 1 stable.

[0133] In an embodiment of the present invention, the partition plate 5 is arranged outside the liquid storage box body 1 for supporting the liquid storage box body 1.

[0134] In an embodiment of the present invention, the partition plate 5 is arranged below the liquid storage box body 1. The liquid storage box body 1 is inserted into the push rod assembly 2, and a part of the liquid storage box body 1 close to the push rod assembly 2 abuts against the partition plate 5, so that the partition plate 55 can be used to support the liquid storage box body 1, thereby preventing the liquid storage box body 1 from moving or being displaced.

[0135] In an embodiment of the present invention, the installation groove 3 is detachably arranged inside the partition plate 5.

[0136] In an embodiment of the present invention, the installation groove 3 is arranged inside the partition plate 5. A through hole penetrates through the partition plate 5, and the installation groove 3 is embedded in the through hole, so that the installation groove 3 can be disassembled. In this way, when there is more liquid collected in the installation groove 3, the user needs to clean the installation groove 3 regularly. The installation groove 3 can be disassembled separately for cleaning to prevent liquid residue from polluting the installation groove 3 and improve the user experience.

[0137] In an embodiment of the present invention, the dispenser further includes a dispensing pump, and the dispensing pump includes a liquid suction hole 111 and a liquid discharge port.

[0138] In an embodiment of the present invention, the liquid suction hole 111 communicates with the liquid collection channel 4, and the liquid discharge port communicates with an external device.

[0139] In an embodiment of the present invention, after the liquid storage box body 1 is inserted into the push rod assembly 2, the push rod assembly 2 is inserted into the liquid collection channel 4, and the ejector rod 41 pushes the liquid leakage prevention mechanism 24 to open the liquid outlet 232, so that the liquid flows into the liquid collection channel 4. The dispensing pump is in a working state, sucking the liquid into the dispensing pump through the liquid suction hole 111, and then discharging the liquid into the connected external device through the liquid discharge port of the dispensing pump, thereby realizing the liquid dispensing process.
