Description

Technical Field

[0001] This utility model relates to the technical field of clothing processing equipment, specifically to a dispensing device for clothing processing equipment. Background Technology

[0002] Currently, laundry detergent dispensers have become indispensable household appliances in people's daily lives. The level of intelligence in these dispensers is also increasing. To address the current problem of inaccurate detergent dosage, automatic detergent dispensing devices have been added to these machines. By inserting the dispenser into the detergent dispenser, the dispenser automatically extracts the appropriate amount of detergent from the dispenser based on the type of clothing placed inside, thus participating in the detergent treatment process.

[0003] For example, Chinese Patent Publication No. CN114921933A, entitled "An Automatic Dispensing Device for a Washing Machine and a Washing Machine," addresses the problem of additive leakage through the one-way ventilation structure on the additive box, which causes the dispensing device to malfunction. The invention employs a separate ventilation pipe on the dispenser, with a ventilation channel within the pipe. The air inlet of the ventilation channel has a one-way ventilation structure to prevent additive overflow. However, in actual use, when the ventilation channel is inserted into the additive box, a large amount of additive enters the channel up to the one-way ventilation structure at the air inlet. Additive residue remains in the ventilation channel. When the additive box is removed, the remaining additive drips down, contaminating the clothing processing equipment near the ventilation channel. Utility Model Content

[0004] The purpose of this invention is to provide a dispensing device for clothing processing equipment, which can effectively solve the problem that existing ventilation channels are prone to leaving a large amount of additives.

[0005] To solve the above-mentioned technical problems, this utility model is achieved through the following technical solution:

[0006] The garment handling equipment includes a dispensing device:

[0007] Dispenser, including a connector having a venting channel; and

[0008] An additive container includes a container body for storing additives, the container body having a first pair of interfaces and a sealing component for closing the first pair of interfaces;

[0009] When the additive container is installed on the dispenser, the connecting pipe opens the sealing component and enters the inner cavity of the container body through the first connecting interface. The venting channel connects the inner cavity of the container body and introduces external fluid into the container body. The part of the venting channel that enters the container body is provided with a one-way venting component, which limits the fluid to flow unidirectionally in the direction of entering the inner cavity of the container body.

[0010] In the dispensing device of the above-mentioned clothing processing equipment, the one-way breathable component includes: a one-way breathable valve core, installed in the breathable channel; and a valve cover, which is installed on the one-way breathable valve core, and the valve cover is located at the end of the connecting pipe that is inserted into the container body.

[0011] In the dispensing device of the above-mentioned garment processing equipment, a first sealing ring is provided between the valve cover and the connecting pipe to prevent the additive from entering the air passage from between the valve cover and the connecting pipe.

[0012] In the dispensing device of the above-mentioned clothing processing equipment, the first sealing component includes a first valve seat fixed on the container body and a first valve core slidably disposed in the first valve seat, and the end face of the valve cover is in contact with the end face of the first valve core.

[0013] In the dispensing device of the above-mentioned clothing processing equipment, an outer sleeve that can slide relative to the connecting pipe is provided on the outer periphery of the connecting pipe, and a second sealing ring is provided between the connecting pipe and the outer sleeve next to the valve cover.

[0014] In the dispensing device of the above-mentioned clothing processing equipment, the one-way breathable component further includes a spring, which is disposed between the one-way breathable valve core and the valve cover. The spring pushes the one-way breathable valve core to close the breathable channel.

[0015] In the dispensing device of the above-mentioned clothing processing equipment, the valve cover and the connecting pipe are connected by threads, and the valve cover and the connecting pipe are also provided with anti-loosening components to prevent the valve cover from rotating in the unscrewing direction.

[0016] In the dispensing device of the aforementioned clothing processing equipment, the air outlet of the ventilation channel faces downwards.

[0017] In the dispensing device of the above-mentioned clothing processing equipment, the connecting pipe also has a liquid extraction channel that is independently set relative to the ventilation channel. The liquid extraction channel is connected to the inner cavity of the container body and draws out the fluid in the container body.

[0018] In the dispensing device of the above-mentioned clothing processing equipment, the dispenser further includes a liquid extraction pipe with a liquid extraction channel. The container body is provided with a second pair of interfaces and a second sealing component that closes the second pair of interfaces. When the additive container is installed in the dispenser, the connecting pipe opens the second sealing component and enters the inner cavity of the container body through the second pair of interfaces. The liquid extraction channel connects to the inner cavity of the container body and draws out the fluid inside the container body.

[0019] Compared with the prior art, the advantages of this utility model are:

[0020] By incorporating a one-way venting component at the point where the venting channel enters the container body, the problem of significant additive residue in current venting channels is solved. Since the outlet of the venting channel only needs to be within the container body after the connecting pipe is inserted into the additive container, meaning the length of the venting channel entering the container body is relatively short, the one-way venting component within the container body, with its short distance from the outlet or its proximity to the outlet, results in minimal or no additive residue remaining in the venting channel. Furthermore, after the additive container is removed, any remaining additive is less likely to drip, significantly reducing the risk of additive contamination of the garment processing equipment. Moreover, the one-way venting component restricts fluid flow in one direction only, allowing outside air to flow into the container body while preventing additive from flowing back towards the venting channel inlet. This not only prevents additive from overflowing from the connecting pipe but also allows outside fluid to smoothly enter the container body.

[0021] Furthermore, the one-way venting component includes: a one-way venting valve core installed in the venting channel; and a valve cover mounted on the one-way venting valve core, the valve cover being located at the end of the connecting pipe inserted into the container body. The valve cover facilitates the installation of the one-way venting valve core and provides protection for it. Since the valve cover is located at the end of the connecting pipe inserted into the container body, it does not affect the airtightness between the connecting pipe's peripheral wall and the container body when the connecting pipe is inserted into the container body.

[0022] Furthermore, a first sealing ring is provided between the valve cover and the connecting pipe to prevent the additive from entering the venting channel between the valve cover and the connecting pipe. By providing the first sealing ring, the sealing performance between the valve cover and the connecting pipe is enhanced. In addition to preventing the additive from entering the venting channel between the valve cover and the connecting pipe, it also prevents liquid in the venting channel from leaking out between the two when the additive container is pulled out.

[0023] Furthermore, the first sealing component includes a first valve seat fixed to the container body and a first valve core slidably disposed within the first valve seat, with the end face of the valve cover abutting against the end face of the first valve core. This reduces the gap between the end face of the valve cover and the end face of the first valve core, thereby reducing or preventing additives from accumulating between them, and also reducing or preventing additives from dripping from this portion after the additive container is removed.

[0024] Furthermore, an outer sleeve that can slide relative to the connecting pipe is provided around the outer periphery of the connecting pipe, and a second sealing ring is provided between the connecting pipe and the outer sleeve next to the valve cover. When the connecting pipe is not inserted into the additive container, the outer sleeve protects the connecting pipe, and when the connecting pipe is pulled out from the first sealing component, the second sealing ring prevents the additive remaining in the venting channel from flowing out from between the outer sleeve and the connecting pipe.

[0025] Furthermore, the one-way venting component also includes a spring, which is disposed between the one-way venting valve core and the valve cover. The spring pushes the one-way venting valve core to close the venting channel. When no other external force is applied, the spring pushes the one-way venting valve core to close the venting channel. However, when the negative pressure inside the container reaches a certain level, the one-way venting valve core overcomes the spring force to open the venting channel, allowing external fluid to enter the container body.

[0026] Furthermore, the valve cover and the connecting pipe are connected by threads, and both the valve cover and the connecting pipe are provided with anti-loosening components to prevent the valve cover from rotating in the unscrewing direction. The threaded connection facilitates the installation of the valve cover on the connecting pipe, and the anti-loosening components prevent the valve cover from becoming loose, thus avoiding the accumulation of additives between the valve cover and the connecting pipe.

[0027] Furthermore, the air outlet of the ventilation channel faces downwards. This downward-facing opening allows the additives entering the ventilation channel to flow out automatically under their own weight, preventing additives from accumulating inside the ventilation channel.

[0028] Furthermore, the connecting pipe also has a liquid extraction channel that is independently configured relative to the venting channel. The liquid extraction channel connects to the inner cavity of the container body and draws out the fluid inside the container body. Integrating both the liquid extraction channel and the venting channel into the connecting pipe reduces the overall size of the dispenser and eliminates the need for multiple connecting ports on the container body, thus improving the airtightness of the container body.

[0029] Furthermore, the dispenser also includes a suction pipe with a suction channel. The container body is provided with a second pair of interfaces and a second sealing component that closes the second pair of interfaces. When the additive container is installed in the dispenser, the connecting pipe opens the second sealing component and enters the inner cavity of the container body through the second pair of interfaces. The suction channel connects to the inner cavity of the container body and leads out the fluid inside the container body. By separating the suction channel and the venting channel, the vent outlet of the venting channel can be far away from the inlet of the suction channel, preventing the fluid entering the container body from the vent outlet from being directly drawn out from the suction channel, thus improving the accuracy of fluid extraction from the suction channel.

[0039] A dispensing device for a garment processing equipment includes: a dispenser 100, including a connecting pipe 110 having a venting channel 120; and an additive container 200, including a container body 210 for storing additives, the container body 210 having a first connecting port 221 and a first sealing component 220 for sealing the first connecting port 221; the connecting pipe 110 is inserted into the container body 210 through the first connecting port 221; the venting channel 120 communicates with the inner cavity of the container body 210 and introduces external fluid into the container body 210; the portion of the venting channel 120 entering the container body 210 is provided with a one-way venting component 300, which limits the fluid to flow unidirectionally in the direction of entering the inner cavity of the container body 210.

[0040] By installing a one-way ventilation component 300 at the point where the ventilation channel 120 enters the container body 210, the problem of a large amount of additive residue easily remaining in the ventilation channel 120 is solved. Since the outlet 121 of the ventilation channel 120 only needs to be located within the container body 210 after the connecting pipe 110 is inserted into the additive container 200, meaning the length of the ventilation channel 120 entering the container body 210 is relatively short, the one-way ventilation component 300 is installed at the point where the ventilation channel 120 is located within the container body 210. The short distance between the one-way ventilation component 300 and the outlet 121 of the ventilation channel 120, or the one-way ventilation component 300 being close to the outlet 121, results in very little or no additive residue remaining in the ventilation channel 120. Furthermore, after the additive container 200 is removed, the additive residue remaining in the ventilation channel 120 is less likely to drip off, thus largely preventing residual additives from contaminating the clothing processing equipment. Furthermore, the one-way venting component 300 restricts the fluid to flow in one direction in the direction of entering the inner cavity of the container body 210. That is, the one-way venting component 300 allows outside air to flow into the container body 210, while preventing the additive inside the container body 210 from flowing towards the air inlet of the venting channel 120. This not only prevents the additive from overflowing from the venting channel 120 into the connecting pipe 110, but also allows outside fluid to smoothly enter the container body 210.

[0041] The embodiments of the present invention are described in detail below, examples of which are shown in the accompanying drawings.

[0044] In this utility model, unless otherwise specified or limited, the terms "installed," "connected," "connect," "fixed," etc. should be understood in a broad sense. For example, they can refer to fixed connection, detachable connection, or integration; mechanical connection, electrical connection, or communication; direct connection or indirect connection through an intermediate medium; internal communication between two elements or interaction between two elements, unless otherwise specified. For those skilled in the art, the specific meanings of the above terms in this utility model can be understood according to specific circumstances.

[0045] See Figures 1 to 5 This embodiment of the garment processing equipment dispensing device includes a dispenser 100 and an additive container 200. The additive container 200 is mainly used to hold additives and includes a container body 210 for storing additives. The container body 210 is provided with a first pair of interfaces 221 and a first sealing component 220 that closes the first pair of interfaces 221. The dispenser 100 includes a connecting pipe 110 with a venting channel 120. The connecting pipe 110 can be inserted into the first sealing component 220 through the first pair of interfaces 221 and drive the first sealing component 220 to open. The venting channel 120 located in the connecting pipe 110 is connected to the container body 210, allowing external fluid to be introduced into the container body 210. The first sealing component 220 can be a sealing film or a liquid outlet valve. The liquid outlet valve has a self-resetting function and can be reused to prevent unused additives in the additive container 200 from flowing out of the first pair of interfaces 221. Therefore, this embodiment will use the first sealing component 220 as a liquid outlet valve as an example for description.

[0046] The main function of the aforementioned venting channel 120 is that when the additive inside the container body 210 is extracted, a negative pressure will be generated inside the container body 210. The generation of negative pressure will hinder the additive from being extracted further. Therefore, the venting channel 120 is set to introduce external fluid into the container body 210, reduce the pressure difference between the inside and outside of the container body 210, and make it easier for the additive to be extracted from the container body 210.

[0047] After the connecting pipe 110 is inserted into the first sealing component 220, the ventilation channel 120 inside the connecting pipe 110 is connected to the container body 210. The additive inside the container body 210 will flow into the ventilation channel 120. When the container body 210 is pulled out, the additive remaining in the ventilation channel 120 will flow out from the ventilation channel 120, thereby contaminating the garment processing equipment. Therefore, a one-way ventilation component 300 is set at the part of the ventilation channel 120 that enters the first sealing component 220. The reason for setting it at the part of the ventilation channel 120 that enters the first sealing component 220 is to allow the ventilation component to be as close as possible to or close to the air outlet 121 of the ventilation channel 120, reducing the distance between the one-way ventilation component 300 and the air outlet 121, that is, reducing the amount of additive remaining in the ventilation channel 120. The one-way venting component 300 restricts the flow of fluid in one direction in the direction of entering the inner cavity of the container body 210. That is, the one-way venting component 300 only allows fluid to flow into the container body 210 and does not allow fluid to flow back through the one-way venting component 300. This ensures that when a negative pressure is generated in the container body 210, external fluids such as air can enter the container body 210 through the one-way venting component 300, while the additives in the container body 210 will not flow towards the air inlet of the venting channel 120 through the one-way venting component 300.

[0048] Furthermore, in this embodiment, the one-way venting component 300 is a one-way valve with a valve core. Its specific structure includes a one-way venting valve core 310 and a valve cover 320. The one-way venting valve core 310 is installed in the venting channel 120. The movement of the one-way venting valve core 310 can open or close the venting channel 120. In this embodiment, the venting channel 120 serves as a valve seat, and the one-way venting valve core 310 is slidably disposed within the venting channel 120, thereby controlling the opening and closing of the venting channel 120. The valve cover 320 is modified onto the one-way venting valve core 310. After the one-way venting valve core 310 is installed, the valve cover 320 protects it. The valve cover 320 is located at the end of the connecting pipe 110 inserted into the first sealing component 220. Since the connecting pipe 110 needs to be inserted into the first sealing component 220, in order to avoid leakage between the connecting pipe 110 and the first sealing component 220 after the connecting pipe 110 is inserted into the first sealing component 220, a high degree of airtightness is required between the peripheral wall of the connecting pipe 110 and the first sealing component 220. Therefore, the valve cover 320 is set at the end of the first sealing component 220 to avoid the installation error of the valve cover 320 affecting the aforementioned airtightness.

[0049] Specifically, the valve cover 320 and the connecting pipe 110 can be connected by threads. Generally, an external thread is provided at the end of the connecting pipe 110 that inserts into the first sealing component 220, and an internal thread is provided on the valve cover 320. The two are connected by threads, and the outer diameter of the valve cover 320 is less than or equal to the outer diameter of the connecting pipe 110 to avoid the valve cover 320 affecting the sealing performance of the peripheral wall of the connecting pipe 110 and the first sealing component 220. The threaded connection facilitates the installation of the valve cover 320 and the connecting pipe 110. Furthermore, a loosening component can be provided on the valve cover 320 and the connecting pipe 110 to prevent the valve cover 320 from rotating in the unscrewing direction. The loosening component can be provided with a first and second elastic abutment on the valve cover 320 and the connecting pipe 110, or the elasticity of the plastic material of the valve cover 320 and the connecting pipe 110 itself can be utilized. When the valve cover 320 is screwed into the connecting pipe 110 and about to be tightened, the first abutment or the second abutment undergoes elastic deformation, allowing the first abutment to pass over the second abutment. The first and second abutment then form an abutment along the direction in which the valve cover 320 is screwed out, thus preventing the valve cover 320 from loosening under normal use. Alternatively, the valve cover 320 can be fixed to the connecting pipe 110 by bonding or welding, which also serves the purpose of preventing the valve cover 320 from loosening.

[0050] Furthermore, since the valve cover 320 is fixedly connected to the connecting pipe 110 only after the one-way vent valve core 310 is installed into the vent channel 120, a first sealing ring 330 is provided between the valve cover 320 and the connecting pipe 110 to prevent the additive from entering the vent channel 120 from between the valve cover 320 and the connecting pipe 110, thereby increasing the airtightness of the valve cover 320 and the connecting pipe 110.

[0051] The first sealing component 220 includes a first valve seat 222 fixed to the container body 210 and a first valve core 223 slidably disposed within the first valve seat 222. The first valve seat 222 is cylindrical in shape, with one end connected to the first connecting port 221. The first valve core 223 is slidably disposed within the first valve seat 222 and slides along the axial direction of the first valve seat 222. A notch 224 is provided on the peripheral wall of the first valve seat 222. After the connecting pipe 110 is inserted into the first valve seat 222, the connecting pipe 110 pushes the first valve core 223. The gap 224 is moved to allow the outlet 121 of the venting channel 120 to communicate with the container body 210 through the gap 224; or after the first valve core 223 slides relative to the first valve seat 222, a gap appears between the first valve core 223 and the first valve seat 222 that communicates with the inside of the container body 210. After the connecting pipe 110 is inserted into the first valve seat 222, the outlet 121 of the venting channel 120 communicates with the container body 210 through the gap, thereby enabling the venting channel 120 to deliver fluid into the container body 210. In order to more smoothly push the first valve core 223 to move when the connecting pipe 110 is inserted into the first sealing component 220, the end face of the valve cover 320 at the end of the connecting pipe 110 is fitted with the end face of the first valve core 223 corresponding to the end face of the connecting pipe 110, so as to maximize the contact surface between the two. On the one hand, this ensures that the force is balanced when the first valve core 223 slides, and on the other hand, it reduces the space between the end face of the valve cover 320 and the end face of the first valve core 223, so as to prevent the additives contained in these spaces from flowing out after the additive container 200 is pulled out.

[0052] The dispenser 100 also includes an outer tube 130, with a connecting tube 110 slidably disposed within it. A return element, such as a spring 340 or a retaining clip, is also connected to the outer tube 130. When the additive container 200 mates with the connecting tube 110, the container body 210 pushes the outer tube 130 to move, allowing the connecting tube 110 inside the outer tube 130 to insert into the first sealing component 220. The outer tube 130 protects the connecting tube 110 when it is not inserted into the additive container 200, and this design does not affect the mating of the connecting tube 110 with the additive container 200. A second sealing ring 140 is provided between the connecting tube 110 and the outer tube 130 near the valve cover 320. The second sealing ring 140 is located between the air outlet 121 and the valve cover 320. When the additive container 200 is withdrawn, as the outer sleeve 130 returns to its original position, the second sealing ring 140 seals the connecting pipe 110 behind the valve cover 320. Even if there is any additive residue on the connecting pipe 110, it will be sealed between the connecting pipe 110 and the outer sleeve 130 by the second sealing ring 140, thereby reducing the dripping of additive residue on the connecting pipe 110. To achieve the above effect, the second sealing ring 140 needs to be as close as possible to the valve cover 320. After the connecting pipe 110 is inserted into the first valve seat 222, the second sealing ring 140 can also be tightly attached to the inner wall of the first valve seat 222.

[0053] The one-way venting component 300 also includes a spring 340, which is disposed between the one-way venting valve core 310 and the valve cover 320. When the one-way venting valve core 310 generates negative pressure inside the container body 210, it is pushed to slide by the external air pressure, compressing the spring 340 to accumulate elastic potential energy. As the one-way venting valve core 310 slides, it opens the venting channel 120. When the pressure difference between the inside and outside of the container body 210 is not large, the external pressure is insufficient to overcome the elastic potential energy of the spring 340. The spring 340 will drive the one-way venting valve core 310 to slide and close the venting channel 120, thereby realizing the automatic opening and closing of the one-way venting component 300.

[0054] Based on the above embodiments, the air outlet 121 of the venting channel 120 faces downward. When the additive liquid level is lower than the air outlet 121 or when the additive container 200 is pulled out, the additive that has entered the venting channel 120 can automatically flow out of the venting channel 120, thereby reducing the amount of additive remaining in the venting channel 120 and avoiding or reducing additive dripping.

[0055] In addition to the venting channel 120, the dispenser 100 also has a liquid extraction channel 150. The liquid extraction channel 150 can be configured in two ways: either both the liquid extraction channel 150 and the venting channel 120 are connected to a single connecting pipe 110, or each is connected to a separate connecting pipe 110. The two configuration methods for the liquid extraction channel 150 are described below:

[0056] The connecting pipe 110 is provided with an independent venting channel 120 and a liquid extraction channel 150. The liquid extraction channel 150 connects to the inner cavity of the container body 210 and draws out the fluid in the container body 210. The liquid extraction channel 150 and the venting channel 120 are integrated in a single connecting pipe 110, which simplifies the structure of the dispenser 100, improves the integration of the dispenser 100, and enhances the sealing effect of the additive container 200. It can also reduce or prevent additives from entering the venting channel 120, prevent additives from overflowing the dispensing device and damaging the clothing processing equipment, and ensure the cleanliness of the entire clothing processing equipment.

[0057] The dispenser 100 includes a suction tube with a suction channel 150. The container body 210 is provided with a second pair of interfaces and a second sealing component that closes the second pair of interfaces. The suction tube is inserted into the container body 210 through the second pair of interfaces and opens the second sealing component. The suction channel 150 connects to the inner cavity of the container body 210 and draws out the fluid inside the container body 210. This design helps to reduce the structural complexity of the suction tube and the connecting tube 110, and provides sufficient spacing between the suction tube and the connecting tube 110. Fluid entering the container body 210 from the vent channel 120 of the connecting tube 110 is not easily sucked out by the suction channel 150 immediately, ensuring that the suction channel 150 sucks out a sufficient amount of additive each time. The second sealing component can be a sealing film or a liquid outlet valve. Preferably, the second sealing component is a liquid outlet valve, and its structure is the same as that of the first sealing component.

[0058] The connecting pipe 110 with the above structure has a one-way ventilation component 300 in the part of the ventilation channel 120 of the connecting pipe 110 that enters the first sealing component 220. This makes the amount of additive remaining in the ventilation channel 120 very small or almost non-existent. After the additive container 200 is pulled out, it can effectively prevent the residual additive from dripping, thereby preventing the dripping additive from contaminating the clothing processing equipment and keeping the entire clothing processing equipment clean.

[0059] The above description is only a specific embodiment of the present utility model, but the technical features of the present utility model are not limited thereto. Any changes or modifications made by those skilled in the art within the scope of the present utility model are covered by the patent scope of the present utility model.
