Technical Field

[0001] This invention relates to the field of washing equipment technology, and more specifically, to a dispensing device and a washing device. Background Technology

[0002] Clothing handling devices, such as the detergent dispensing module in a washing machine, dispense detergent by hand or electric means. Such washing machines usually have valves on the dispensing channels to open and close the dispensing pipeline; however, the existing valve opening and closing methods are cumbersome or costly, and there is room for improvement. Summary of the Invention

[0003] The present invention aims to at least partially solve one of the aforementioned technical problems in the prior art.

[0006] The dispensing device proposed in this invention improves the space utilization of the dispensing device by enabling the valve assembly and dispensing pump to work together through a single drive structure. This facilitates increasing the space of the dispensing chamber within the device and thus increasing the liquid output.

[0054] Embodiments of the present invention are described in detail below. Examples of these embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals denote the same or similar elements or elements having the same or similar functions throughout. The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain the present invention, and should not be construed as limiting the present invention.

[0055] In this invention, unless otherwise explicitly specified and limited, "above" or "below" the second feature can include direct contact between the first and second features, or contact between the first and second features through another feature between them. Furthermore, "above," "over," and "on top" of the second feature includes the first feature directly above or diagonally above the second feature, or simply indicates that the first feature is at a higher horizontal level than the second feature. "Below," "below," and "under" the second feature includes the first feature directly below or diagonally below the second feature, or simply indicates that the first feature is at a lower horizontal level than the second feature.

[0056] In washing equipment, water and treatment agents (such as detergent, fabric softener, etc.) need to be added to the washing chamber (e.g., the garment processing chamber) to clean the clothes and make them cleaner. In the dispensing device, to prevent liquid from flowing back into the dispensing pump through the dispensing port, a valve assembly is usually installed at the dispensing port to ensure the reliability of the dispensing device.

[0057] During the treatment agent dispensing process, it is necessary to simultaneously control the valve assembly to open the treatment agent dispensing orifice and control the dispensing pump to pump out the treatment agent to ensure smooth dispensing. Therefore, two sets of drive structures need to be designed within the dispensing device to control both the valve assembly opening the treatment agent dispensing orifice and the dispensing pump pumping out the treatment agent. This results in a complex structure for the dispensing device and high manufacturing costs for the washing equipment. Furthermore, when the dispensing device does not require treatment agent dispensing, the valve assembly opening the treatment agent dispensing orifice can cause leakage, affecting the user experience.

[0058] Therefore, this invention provides a dispensing device that can control the dispensing pump to operate simultaneously by driving the valve assembly to open the first treatment agent dispensing hole using a single driving component. Thus, a single driving component can drive both the valve assembly and the dispensing pump to work together, reducing the number of driving structures within the dispensing device, making the overall structure of the dispensing device simpler, reducing manufacturing costs, and because the valve assembly and the dispensing pump operate simultaneously, the valve assembly only opens the treatment agent dispensing hole when treatment agent needs to be dispensed, avoiding leakage from the dispensing device and making the device more reliable overall.

[0059] The following is for reference. Figures 1-20 A dispensing device 1000 according to an embodiment of the present invention is described.

[0060] like Figures 1-3 As shown, the dispensing device 1000 according to an embodiment of the present invention may include: a dispensing pump 200, a valve assembly 400, and a drive component 102.

[0061] The dispensing device 1000 has a first dispensing hole 307 through which the treatment agent can enter the washing equipment. A valve assembly 400 is movably disposed at the first dispensing hole 307 for opening or closing the first dispensing hole 307. By controlling the movement of the valve assembly 400 at the first dispensing hole 307, the opening and closing of the first dispensing hole 307 can be controlled. Therefore, by controlling the opening and closing of the first dispensing hole 307, the amount of treatment agent dispensed can be better controlled, achieving a better dispensing effect.

[0062] When driven by an external source, the dispensing pump 200 can pump out the treatment agent. The dispensing pump 200 is connected to the first dispensing port 307, meaning that the dispensing pump 200 can dispense the treatment agent through the first dispensing port 307 so that the treatment agent can be dispensed into the washing equipment.

[0063] The drive component 102 can move when pressed. The drive component 102 cooperates with both the valve assembly 400 and the dispensing pump 200. When the drive component 102 is pressed, it drives the valve assembly 400 to open the first dispensing port 307 and simultaneously drives the dispensing pump 200 to dispense the treatment agent into the first dispensing port 307. In other words, the drive component 102 can control the dispensing pump 200 to operate while simultaneously driving the valve assembly 400 to open the first dispensing port 307. The treatment agent pumped out by the dispensing pump 200 can directly enter the dispensing chamber 302 through the opened first dispensing port 307, thus realizing the dispensing of the treatment agent.

[0064] In other words, a single drive component 102 can simultaneously drive the valve assembly 400 and the dispensing pump 200 to work together, reducing the number of drive structures within the dispensing device 1000, making the overall structure of the dispensing device 1000 simpler, reducing manufacturing costs, and because the valve assembly 400 and the dispensing pump 200 work simultaneously, the valve assembly 400 will only open the first dispensing port 307 when the treatment agent needs to be dispensed, avoiding leakage of the dispensing device 1000 and making the device more reliable overall.

[0065] Furthermore, since the valve assembly 400 and the dosing pump 200 work together, the treatment agent can be intermittently added during the washing process without leakage, thus improving the washing effect of the washing equipment.

[0066] Reference Figure 2 The drive component 102 and the dispensing pump 200 are connected by a first transmission unit. The first transmission unit can convert the pressure on the drive component 102 into the driving force required by the dispensing pump 200 to dispense the treatment agent. The first transmission unit makes the overall structure of the dispensing device 1000 simpler and easier to set up.

[0067] like Figures 1-3 As shown, the drive component 102 and the valve assembly 400 are connected by a second transmission unit. Because the drive component 102 and the valve assembly 400 move in different directions during the deployment process, as... Figure 2 and Figure 3 As shown in the figure, the AB direction is the direction of movement of the driving component, and the CD direction is the direction of movement of the valve assembly. Therefore, a second transmission part is provided between the driving component 102 and the valve assembly 400 to convert the movement of the driving component 102 along the AB direction into the movement of the valve assembly 400 along the CD direction.

[0068] According to the dispensing device of the present invention, the overall structure of the dispensing device 1000 is simpler, reducing the manufacturing cost of the washing equipment. Since the valve assembly 400 and the dispensing pump 200 work simultaneously, the valve assembly 400 will only open the first dispensing hole 307 when the treatment agent needs to be dispensed, thus avoiding leakage of the dispensing device 1000 and making the device more reliable overall.

[0069] like Figure 3 As shown, the first transmission part and the second transmission part are located on different sides of the drive component 102, so that the first transmission part and the second transmission part can transmit power with the drive component 102 at different positions, so that the first transmission part and the second transmission part do not affect each other in movement, and the overall structure of the dispensing device 1000 is more reasonable.

[0070] According to some embodiments of the present invention, the first transmission part and the second transmission part are respectively formed as rotating members, so as to utilize the rotation of the rotating members to change the transmission direction of the motion trend of the drive member, thereby enabling the drive member 102 to simultaneously drive the valve assembly 400 and the dispensing pump 200 to work. Since the first transmission part and the second transmission part are located on different sides of the drive member 102, the rotation direction of the first transmission part is opposite to the rotation direction of the second transmission part.

[0071] like Figure 2 As shown, the drive component 102 is adapted to move under pressure, and the direction of movement of the drive component 102 is different from the direction of movement of the valve assembly 400, such as... Figure 2 As shown, the moving direction of the drive component 102 is the AB direction, and the moving direction of the valve assembly 400 is the CD direction. This ensures that the space occupied by the valve assembly 400 does not occupy the space occupied by the drive component 102, so that the drive component 102 and the valve assembly 400 do not interfere with each other in their movements. This facilitates the arrangement of the various components within the dispensing device 1000, making the overall structure of the dispensing device 1000 more rational.

[0072] like Figure 1 and Figure 2 As shown, according to some embodiments of the present invention, the valve assembly 400 is movable in the vertical direction, such as... Figure 2 As shown in the figure, the CD direction is the vertical direction. The drive component 102 extends downward at an angle close to the valve assembly 400, and the drive component 102 is movable in the downward angle. Figure 2 As shown in the figure, direction AB is the extension direction of the driving component.

[0073] like Figure 1 and Figure 2As shown, the first transmission part forms a first gear 104, and the driving component 102 includes a first rack 1024. The first rack 1024 can mesh with the first gear 104. The driving component 102 is adapted to move under the action of pressing and drive the first gear 104 to rotate through the first rack 1024, so as to drive the dispensing pump 200 to dispense the treatment agent.

[0074] Specifically, when the drive component 102 is pressed, the drive component 102 is adapted to move in a straight line, the first rack 1024 moves along with the linear movement of the drive component 102, the first gear 104 meshes with the first rack 1024, and can convert the linear movement of the first rack 1024 into the rotational movement of the first gear 104, so that the dispensing pump 200 can rotate under the drive of the first gear 104, thereby enabling the dispensing pump 200 to dispense the treatment agent.

[0075] like Figure 2 As shown, the first rack 1024 extends along the moving direction of the drive component 102 so that the first rack 1024 transmits the movement trend of the drive component 102 to the first gear 104. The meshing teeth of the first rack 1024 extend upward so that the first gear 104 and other transmission structures for driving the dispensing pump 200 can be arranged above the first rack 1024 so as to facilitate the arrangement of the dispensing device.

[0076] Reference Figure 1 The dispensing pump 200 includes a pump housing 202. The pump housing 202 supports and protects the rotating component 203 within the dispensing pump 200 while simultaneously creating a relatively enclosed space within the pump 200, thus establishing a pressure differential and ensuring the normal operation of the dispensing pump 200. The dispensing pump 200 also includes at least one rotating component 203, which is disposed within the pump housing 202. The rotation of the rotating component 203 creates a pressure differential within the space of the pump housing 202, ensuring the normal operation of the dispensing pump 200.

[0077] The first transmission part rotates coaxially with at least one rotating member 203, so that the rotation of the first transmission part can drive the rotating member 203 to rotate.

[0078] Specifically, in some embodiments, when the drive component 102 is pressed, the drive component 102 is adapted to move in a straight line, the first rack 1024 moves along with the linear movement of the drive component 102, the first gear 104 meshes with the first rack 1024, and can convert the linear movement of the first rack 1024 into the rotational movement of the first gear 104. The first gear 104 rotates coaxially with the rotating component 203, thereby converting the rotational movement of the first gear 104 into the rotation of the rotating component 203. The rotation of the rotating component 203 can form a pressure difference in the space inside the pump housing 202, providing power for the dispensing of the treatment agent and ensuring the normal operation of the dispensing pump 200.

[0079] like Figure 2 As shown, the rotating part 203 and the inner cavity of the pump housing 202 define a liquid suction area 205 and a liquid discharge area 206. The liquid discharge area 206 is connected to the first dispensing hole 307. Under the pressure of the driving part 102, the dispensing pump 200 causes the treatment agent to enter from the liquid suction area 205 and be discharged from the liquid discharge area 206.

[0080] Specifically, the rotating component 203 is rotatably disposed within the pump housing 202, thereby forming a liquid absorption zone 205 and a liquid discharge zone 206 within the pump housing 202. The inlet of the treatment agent corresponds to the liquid absorption zone 205, and the liquid discharge zone 206 is connected to the first dispensing hole 307. When the dispensing device 1000 is in its initial state, when the user presses the driving component 102, causing the driving component 102 to move in a straight line, the driving component 102 drives the first transmission unit to rotate, which in turn drives the rotating component 203 to rotate. The rotation of the rotating component 203 generates a negative pressure in the liquid absorption zone 205 and a positive pressure in the liquid discharge zone 206. Under the action of the pressure difference, the treatment agent at the liquid inlet flows to the liquid discharge zone 206 and is then dispensed into the washing equipment through the first dispensing hole 307.

[0081] For example, the dispensing pump 200 can be a gear pump, and the rotating component 203 can include two meshing gears. One gear rotates coaxially with the first gear 104 to form a driving gear, and the other gear forms a driven gear. The driving gear, the driven gear, and the pump housing define a suction area 205 and a discharge area 206, respectively. As the two gears rotate, the suction and discharge actions are achieved. Of course, the dispensing pump 200 can also be an impeller pump, a plunger pump, or other structures.

[0082] Combination Figure 1 and Figure 2In the illustrated embodiment, the dispensing pump 200 includes a one-way transmission member 204. The one-way transmission member 204 can only transmit movement in one direction to the rotating member 203. The one-way transmission member 204 is disposed between the first transmission part and the rotating member 203. The driving member 102 is adapted to drive the one-way transmission member 204 to rotate via the first transmission part under pressing action, thereby driving the rotating member 203 to rotate. Furthermore, when the driving member 102 moves towards its initial position, the one-way transmission member 204 prevents the rotating member 203 from reversing. Here, the one-way transmission member 204 can be a ratchet.

[0083] In other words, when the drive component 102 drives the dispensing pump 200 to dispense the treatment agent, the drive component 102 is adapted to drive the first transmission part to rotate. At this time, the first transmission part drives the one-way transmission member 204 to rotate, thereby driving the rotating member 203 to rotate. After the drive component 102 stops driving, the drive component 102 is adapted to return to its initial position. At this time, the first transmission part and the one-way transmission member 204 are adapted to rotate in opposite directions under the drive of the drive component 102, while the rotating member 203 disengages from the one-way transmission member 204 and does not rotate.

[0084] It is understandable that by setting a one-way transmission mechanism, the one-way transmission mechanism does not drive the rotating part 203 to move during the process of the drive component 102 returning to the initial position. This helps to prevent the dispensing pump 200 from sucking in the treatment agent in the reverse direction through the first dispensing hole 307, which helps to ensure the accuracy of the treatment agent dispensing. At the same time, during the process of the drive component 102 returning to the initial position, since the one-way transmission mechanism does not drive the rotating part 203 to move, it helps to reduce the resistance of the drive component 102 returning to the initial position, which helps to improve the user's operating experience.

[0085] Reference Figure 3 According to some embodiments of the present invention, a reset member 1031 is provided between the drive member 102 and the dispensing pump 200 to drive the drive member 102 to move toward an initial position. The reset member 1031 is capable of providing a reset force to the drive member 102 when the drive member 102 is pressed away from the initial position, so that the drive member 102 returns to the initial position.

[0086] Reference Figures 1-3 The second transmission part forms a second gear 105, and the driving component 102 includes a second rack 1025. The second rack 1025 can mesh with the second gear 105. The driving component 102 is adapted to move under the action of pressing and drive the second gear 105 to rotate through the second rack 1025, so as to drive the valve assembly 400 to open the first dispensing hole 307.

[0087] Furthermore, the second rack 1025 can indirectly cooperate with the valve assembly 400 through the second gear 105. Specifically, during the movement of the driving component 102, the second rack 1025 will also move simultaneously. The second gear 105 will rotate under the drive of the second rack 1025, and then drive the valve assembly 400 to move, thereby realizing the driving of the valve assembly 400 by the driving component 102.

[0088] Therefore, the second gear 105 can transmit the motion trend of the drive component 102 to the valve assembly 400 when the moving direction of the drive component 102 is different from the moving direction of the valve assembly 400, so as to realize the drive component 102 driving the valve assembly 400.

[0089] Specifically, the second gear 105 can convert the downward movement trend of the drive component 102 into the downward movement trend of the valve assembly 400, pushing the valve assembly 400 to move downward, so as to control the opening and closing of the first dispensing hole 307 by controlling the movement of the valve assembly 400.

[0090] like Figure 2 As shown, the second rack 1025 extends along the moving direction of the drive member 102 so that the second rack 1025 transmits the movement trend of the drive member 102 to the second gear 105. The meshing teeth of the second rack 1025 extend downward so that the second gear 105 and other transmission structures for driving the valve assembly 400 can be arranged above the second rack 1025 so as to facilitate the arrangement of the dispensing device 1000.

[0091] In summary, the meshing teeth of the first rack 1024 extend upwards, and the meshing teeth of the second rack 1025 extend downwards, so that the transmission of the first rack 1024 and the transmission of the second rack 1025 do not interfere with each other, thus ensuring the stable operation of the dispensing device 1000.

[0092] like Figures 1-3 As shown, the valve assembly 400 includes a third rack 404, which meshes with a second gear 105 so that the second gear 105 can drive the third rack 404 to move during rotation, thereby driving the valve assembly 400 to move.

[0093] like Figure 3 As shown, the rotation axis of the second gear 105 extends horizontally, as... Figure 3 As shown in the figure, the direction indicated by EF is horizontal to ensure that the second gear 105 can stably transmit driving force. The second rack 1025 extends in a downward direction to drive the dispensing pump 200 located downwards. Figure 3As shown in the figure, direction AB indicates the extension direction of the second rack 1025, and the third rack 404 extends vertically to enable the valve assembly 400 to move vertically. Figure 3 As shown in the figure, the direction indicated by CD is the up and down direction.

[0094] In some embodiments, such as Figure 3 As shown, the second gear 105 can be mounted on a fixed structure via a pin 1051. The extension direction of the pin 1051 is perpendicular to the extension direction of the second rack 1025 and also perpendicular to the extension direction of the third rack 404. This ensures that the motion trend of the second rack 1025 can be smoothly transmitted to the third rack 404, avoiding any angle between the second gear 105 and the second rack 1025 and the third rack 404, thus ensuring the stable transmission of the motion trend.

[0095] like Figure 14 As shown, according to some embodiments of the present invention, the valve assembly 400 includes a movable valve plate 401 located below the first dispensing hole 307, and the valve plate 401 is used to open and close the first dispensing hole 307. The opening and closing of the first dispensing hole 307 can be controlled by controlling the movement of the valve plate 401. To ensure the sealing effect of the valve plate 401 on the first dispensing hole 307, the diameter of the valve plate 401 is larger than the diameter of the first dispensing hole 307. Specifically, the valve plate 401 is located below the first dispensing hole 307, and the valve assembly 400 controls the opening and closing of the first dispensing hole 307 by moving up and down. When the valve plate 401 moves downward, the first dispensing hole 307 can be opened; when the valve plate 401 moves upward, the first dispensing hole 307 can be closed.

[0096] In some embodiments, the valve assembly 400 further includes a pusher 402 connected to a valve plate 401. The pusher 402 can move under the drive of the drive member 102, thereby moving the valve plate 401. A third rack 40 is connected to the pusher 402 to move the pusher 402. That is, the valve assembly 400 includes a third rack 404, which can be disposed on the pusher 402 and extends along the length direction of the pusher 402, so that the drive member 102 can drive the pusher 402 to move along the length direction of the pusher 402.

[0097] Reference Figure 14The dispensing device 1000 also has a second dispensing hole 308. The first dispensing hole 307 and the second dispensing hole 308 are both located within the dispensing device 1000, enabling different functions and improving the practicality of the dispensing device 1000. The valve assembly 400 is used to simultaneously open and close the first dispensing hole 307 and the second dispensing hole 308. In other words, the opening and closing of the first dispensing hole 307 and the second dispensing hole 308 can be controlled by the valve assembly 400, eliminating the need for additional valves to control the second dispensing hole 308, thus simplifying the structure of the dispensing device 1000.

[0098] like Figures 14-16 As shown, the dispensing device 1000 also includes: a nozzle body 301, in some embodiments, such as Figure 3 As shown, the second gear 105 is mounted on the nozzle body 301 via a pin 1051. The nozzle body 301 defines a dispensing chamber 302, where the mixture of water and treatment agent can be collected and fully mixed before being dispensed into the washing equipment. The nozzle body 301 allows for more thorough mixing of the treatment agent and water, resulting in better washing performance. A first dispensing hole 307 is located in the nozzle body 301 and communicates with the dispensing chamber 302. A second dispensing hole 308 is also located in the nozzle body 301 and communicates with the dispensing chamber 302. The dispensing pump 200, valve assembly 400, and drive component 102 are located in the nozzle body 301 to form a complete dispensing device 1000.

[0099] Specifically, one end of the pusher 402 can pass through the nozzle body 301 and connect with the valve plate 401 located below the first dispensing hole 307. The other end of the pusher 402 can cooperate with the second transmission part that cooperates with the drive member 102, so that the drive member 102 can drive the pusher 402 to move downward and drive the valve plate 401 to move, so as to open and close the first dispensing hole 307.

[0100] like Figure 14 As shown, in some embodiments, the nozzle body 301 has a mounting hole 3013, and the pusher 402 passes through the mounting hole 3013 so that the pusher 402 can be connected to the valve plate 401 located below the first dispensing hole 307.

[0101] In some embodiments, the pusher 402 includes a push rod 4021 and a mounting base 4022. One end of the push rod 4021 is provided with a third rack 404 and extends out of the nozzle body 301 to cooperate with the second transmission member. The other end of the push rod 4021 extends into the nozzle body 301. The mounting base 4022 is disposed in the nozzle body 301, and the middle part of the mounting base 4022 is detachably connected to the other end of the push rod 4021. For example, the mounting base 4022 and the other end of the push rod 4021 can be threadedly engaged. A fixing post is provided at a position off-center of the mounting base 4022, and the valve plate 401 cooperates with the fixing post.

[0102] A specific embodiment of the dispensing device 1000 according to the present invention is described below with reference to the accompanying drawings.

[0103] like Figure 1 As shown, the dispensing device 1000 includes a drive assembly 100, a dispensing pump 200, a nozzle assembly 300, and a valve assembly 400.

[0104] The drive assembly 100 includes an exterior component 101 and a drive component 102.

[0105] The exterior component 101 has an installation channel 1011. The drive component 102 is movably disposed in the installation channel 1011 between a first position and a second position. The drive component 102 can be limited by the exterior component 101 at the first position and the second position to prevent the drive component 102 from disengaging from the installation channel 1011. The installation channel 1011 can also position and guide the movement of the drive component 102, so that the drive component 102 can move within the installation channel 1011 to achieve the purpose of driving the dispensing device 1000.

[0106] The first position is located outside the second position in the extension direction of the mounting channel 1011. When the drive assembly 100 is in its natural state, the drive component 102 is located in the first position outside the mounting channel 1011. When the user needs to drive the dispensing device 1000 through the drive assembly 100, the user presses the drive component 102 to move the drive component 102 inward along the mounting channel 1011 until it moves to the second position. In the second position, the drive component 102 is limited, and the user cannot continue to apply pressure inward to make the drive component 102 continue to move inward.

[0107] The gap between the drive component 102 and the wall of the mounting channel 1011 gradually increases from the outside to the inside as the drive component 102 moves. Because the distance between the drive component 102 and the wall gradually increases with movement, when the user presses the drive component 102, the distance between the drive component 102 and the wall increases further as the drive component 102 moves. Therefore, when the drive component 102 shifts, the distance between the drive component 102 and the wall is greater than the amount of shift during movement, ensuring that a gap is always maintained between the drive component 102 and the wall, allowing the drive component 102 to move smoothly inward.

[0108] When the user presses the drive component 102, the inward movement of the drive component 102 during the pressing process becomes smoother, improving the tactile feel of the drive component 102. Furthermore, because the gap between the outermost drive component 102 and the wall surface is minimal, the aesthetic appearance of the outer trim component 101 is ensured. Moreover, the small gap between the outermost drive component 102 and the wall surface limits the relative offset of the drive component 102 relative to the outer trim component 101, further ensuring smooth movement of the drive component 102 within the mounting channel 1011 and improving the tactile feel.

[0109] like Figure 6 As shown, the cross-sectional area of ​​the mounting channel 1011 gradually expands from the outside to the inside. In other words, the mounting channel 1011 has a flared shape from the outside to the inside, so that during the movement of the driving component 102 from the outside to the inside, the gap between the driving component 102 and the wall gradually increases. As the gap gradually increases, the movement of the driving component 102 inward during the pressing process becomes smoother, thereby improving the operating feel of the driving component 102.

[0110] Reference Figure 10 In the first position, the drive component 102 fits tightly against the wall, ensuring that the gap between the drive component 102 and the exterior component 101 is not visible to the user in its natural state, thus improving the aesthetics of the appearance.

[0111] Furthermore, in the first position, the drive component 102 fits tightly against the wall surface, and the wall surface of the mounting channel 1011 can limit the drive component 102, ensuring that the drive component 102 is stably limited in the first position. As the drive component 102 moves inward, since the cross-sectional area of ​​the mounting channel 1011 gradually expands from the outside to the inside, the gap between the drive component 102 and the wall surface gradually increases from 0. As the gap gradually increases, when the user presses the drive component 102, the inward movement of the drive component 102 during the pressing process becomes smoother, thus improving the operating feel of the drive component 102.

[0112] Furthermore, since the drive component 102 is in close contact with the wall of the mounting channel 1011 in the first position, the relative offset of the drive component 102 relative to the exterior component 101 is small, which further ensures the smoothness of the movement of the drive component 102 within the mounting channel 1011 and improves the operating feel.

[0113] Combination Figure 4 and Figure 5 In the illustrated embodiment, in the first position, a portion of the drive member 102 protrudes from the outer surface of the exterior component 101. The user moves the drive member 102 along the mounting channel 1011 by pressing the portion of the drive member 102 that protrudes from the outer surface of the exterior component 101. This makes the operation of the drive assembly 100 more responsive and easier for the user to apply force to the drive member 102.

[0114] like Figure 6 As shown, the exterior component 101 includes: an exterior panel 1012, which is located outside the drive assembly 100 and can protect the dispensing device 1000 and the drive assembly 100 from the outside, ensuring the operational stability of the dispensing device 1000 and the drive assembly 100. The exterior panel 1012 has an opening through which a portion of the drive assembly 102 protrudes outward to allow the user to apply pressure to the drive assembly 102. A retaining plate 1013 is provided inside the opening, defining an installation channel 1011. One end of the retaining plate 1013 is connected to the edge of the opening to define the installation channel 1011 at the opening. Furthermore, the retaining plate 1013 is located inside the exterior panel 1012 to define the installation channel 1011 inside the opening.

[0115] Furthermore, the enclosure 1013 can limit the movement of the drive component 102, ensuring the stability of the drive component 102. The enclosure 1013 also guides the movement of the drive component 102, ensuring the stability of the drive component 102 during movement.

[0116] Reference Figure 6The drive component 102 has a decorative rib 1021 extending circumferentially therein. The decorative rib 1021 is exposed when the drive component 102 moves inward toward the mounting channel 1011, thereby preventing the gap between the drive component 102 and the outer trim panel 1012 from being observed from the outside during the inward movement of the drive component 102, thus improving aesthetics. The decorative rib 1021 mates with the wall of the mounting channel 1011, ensuring the stability of the drive component 102 during movement, preventing large displacements of the drive component 102 during movement, and making the movement smoother.

[0117] The drive component 102 includes a drive button 1022 and a transmission component 1027. The drive button 1022 and the transmission component 1027 can be integrated to make the overall structure more compact, or they can be separated to achieve a detachable stop fit. The transmission component 1027 cooperates with the dispensing pump 200 and the valve assembly 400 respectively. By pressing the drive button 1022, the user can simultaneously drive the valve assembly 400 and the dispensing pump 200 to dispense the treatment agent into the nozzle assembly 300, realizing one-button dispensing of the treatment agent.

[0118] Reference Figure 4 and Figure 5 The user presses the drive button 1022 to move the drive component 102 inward, thereby driving the dispensing device 1000 to dispense the contents. The drive button 1022 engages with the wall of the mounting channel 1011. In other words, the wall of the mounting channel 1011 limits the drive button 1022 to limit the drive component 102, and guides the movement of the drive button 1022 to guide the movement of the drive component 102.

[0119] Furthermore, decorative ribs 1021 are formed on the inner side of the drive button 1022 to limit the drive button 1022 and thus limit the entire drive component 102.

[0120] Reference Figures 6-9 The drive button 1022 has a mating groove 10221 on its inner side. The transmission component 1027 includes a mating plate 10271. The bottom wall of the mating groove 10221 is in a stop-fitting engagement with the mating plate 10271, enabling the mating transmission to be completed even when the drive button 1022 is separated from the transmission component 1027. The side wall of the mating groove 10221 can limit the mating plate 10271, ensuring the stability of the transmission component 1027. When the drive button 1022 is pressed, the bottom wall of the mating groove 10221 can push the mating plate 10271, so that the transmission component 1027 moves along with the drive button 1022.

[0121] Reference Figures 6-9 The mating groove 10221 extends along the length of the drive button 1022 to ensure reliable mating between the mating groove 10221 and the mating plate 10271. The shape of the mating plate 10271 matches the shape of the mating groove 10221 so that the mating plate 10271 can be precisely positioned within the mating groove 10221, preventing wobbling between the drive button 1022 and the transmission component 1027, and ensuring the stability of the drive button 1022.

[0122] The bottom wall of the mating groove 10221 is provided with a plurality of spaced mating ribs 10222. The mating ribs 10222 not only strengthen the structure of the drive button 1022 and ensure the structural strength of the drive button 1022, but also prevent the mating ribs 10222 from directly mating with the bottom surface of the mating plate 10271, thus avoiding the effect of offsetting errors at the mating point between the drive button 1022 and the transmission component 1027.

[0123] like Figure 2 As shown, the drive button 1022 and the transmission component 1027 are located above the valve assembly 400, so that the drive button 1022 and the transmission component 1027 are located closer to the top, making it easier for the user to control the dispensing device 1000 through the drive button 1022 and the transmission component 1027.

[0124] The drive button 1022 and the transmission component 1027 are adapted to move in a downward direction, thereby driving the valve assembly 400 and the dispensing pump 200. This allows the user to drive the drive button 1022 and the transmission component 1027 by applying pressure downward. Since the user can use gravity when applying pressure downward, it is more ergonomic, making the application process more comfortable and the operation feel better.

[0125] In this embodiment of the invention, the treatment agent can be dispensed simply by pressing the drive button 1022 and the transmission component 1027 diagonally downwards, eliminating the need for an electric dispensing pump. This further reduces the manufacturing cost of the washing equipment and makes it easier for users to control the amount of treatment agent dispensed, thus improving the user experience.

[0126] The dispensing pump 200 includes a pump housing 202, a ratchet, and a rotating component 203. The rotating component 203 includes two meshing gears, one of which rotates coaxially with the first gear 104 to form a driving gear, and the other gear forms a driven gear. The driving gear, the driven gear, and the pump housing define a liquid suction area 205 and a liquid discharge area 206, respectively. As the two gears rotate, the liquid suction and discharge actions are realized.

[0127] The dispensing device also includes a first gear 104, and a ratchet is disposed between the first gear 104 and the rotating member 203. The driving member 102 is adapted to drive the ratchet to rotate through the first gear 104 under the action of pressing to drive the rotating member 203 to rotate. When the driving member 102 moves toward the initial position, the ratchet prevents the rotating member 203 from reversing.

[0128] A first rack 1024 is provided on one side of the transmission component 1027. The first rack 1024 can mesh with the first gear 104. When the drive button 1022 is pressed, the transmission component 1027 is adapted to move under the pressing action and drive the first gear 104 to rotate through the first rack 1024. The first gear 104 then drives the ratchet to rotate, and the ratchet drives the rotating component 203 to rotate, so as to drive the dispensing pump 200 to dispense the treatment agent.

[0129] The valve assembly 400 includes a movable valve plate 401 and a pusher 402. The pusher 402 includes a push rod 4021 and a mounting base 4022. The middle part of the mounting base 4022 is detachably connected to the other end of the push rod 4021. A fixing post is provided at a position off-center from the middle of the mounting base 4022, and the valve plate 401 cooperates with the fixing post. A third rack 404 is provided on one end of the push rod 4021.

[0130] The dispensing device also includes a second gear 105, and a second rack 1025 is provided on the other side of the transmission component 1027. The second rack 1025 can indirectly cooperate with the valve assembly 400 through the second gear 105. Specifically, during the movement of the driving component 102, the second rack 1025 will also move at the same time. The second gear 105 rotates under the drive of the second rack 1025, and then drives the third rack 404 meshing with the second gear 105, so that the second gear 105 can drive the third rack 404 to move during the rotation, thereby driving the valve assembly 400 to move. This realizes the driving of the valve assembly 400 by the driving component 102.

[0131] Reference Figure 1 and Figure 3 A reset member 1031 is provided between the transmission member 1027 and the dispensing pump 200 to drive the drive button 1022 to move toward the initial position. The reset member 1031 can provide a reset force to the drive button 1022 and the transmission member 1027 when they move to their limit positions, so that the drive button 1022 and the transmission member 1027 return to their initial positions.

[0132] like Figure 3As shown, the transmission member 1027 has a positioning part 1026 on the side opposite to the drive button 1022. One end of the reset member 1031 cooperates with the positioning part 1026 so that the reset member 1031 can be stably set between the transmission member 1027 and the dispensing pump 200 to achieve stable reset.

[0133] Specifically, the reset member 1031 is connected to the transmission member 1027. One end of the reset member 1031 cooperates with the positioning part 1026 of the transmission member 1027, and the other end of the reset member 1031 is fixedly disposed with the dispensing pump 200. When the drive button 1022 is pressed, the drive button 1022 and the transmission member 1027 are adapted to move diagonally downward from the initial position and compress the reset member 1031, so that the reset member 1031 has a reset force. After the drive button 1022 and the transmission member 1027 move to the limit position, the pressing force on the drive button 1022 disappears. At this time, the reset member 1031 is adapted to apply a reset force to the transmission member 1027 to drive the drive button 1022 and the transmission member 1027 to move back to the initial position, thereby resetting the drive button 1022 and the transmission member 1027.

[0134] Furthermore, while the reset component 1031 drives the transmission component 1027 to reset, it also drives the valve assembly 400 to reset, thereby realizing the overall reset of the dispensing device 1000.

[0135] The positioning part 1026 forms a positioning groove to achieve a better positioning effect.

[0136] like Figure 13 As shown, the nozzle assembly 300 includes a nozzle body 301. A dispensing chamber 302 is defined within the nozzle body 301. The nozzle body 301 includes a base plate 3011, located at the bottom of the nozzle body 301. The base plate 3011 forms the bottom wall of the dispensing chamber 302. After the mixture of water and treatment agent collects in the dispensing chamber 302, it flows downwards under gravity and is received by the base plate 3011, which forms the bottom wall of the dispensing chamber 302. Furthermore, since the base plate 3011 has multiple spaced-apart through holes 3012, each through hole 3012 communicating with the dispensing chamber 302, the liquid in the dispensing chamber 302 can flow out through the through holes 3012. Therefore, the mixture of water and treatment agent received on the base plate 3011 can flow out through the through hole 3012 opened on the base plate 3011, so that the mixture of water and treatment agent that is evenly mixed in the dispensing chamber 302 can be dispensed into the washing equipment.

[0137] Furthermore, under the diversion effect of multiple spaced through holes 3012, the water flow after mixing with the treatment agent becomes more uniform and the flow rate decreases after passing through multiple through holes 3012. This avoids the phenomenon of liquid splashing caused by the high-velocity water flow directly impacting clothing, thus improving the user experience.

[0138] like Figure 16 As shown, the through hole 3012 is formed into a round hole to facilitate the processing of the nozzle body 301 base plate 3011. In some embodiments, the through hole 3012 is formed into a square hole. Of course, the through hole 3012 can also be formed into a triangular hole or other shapes of through hole 3012, which is not limited here.

[0139] Reference Figure 16 The through hole 3012 is located in the middle of the base plate 3011. To ensure the connection strength between the base plate 3011 and the nozzle body 301, the through holes 3012 are not opened at both ends of the base plate 3011. To prevent the water flow received at both ends of the base plate 3011 from stagnating at both ends, the two ends of the base plate 3011 gradually extend downwards along the direction close to the middle of the base plate 3011. Thus, the water flow received at both ends of the base plate 3011 can flow towards the middle of the base plate 3011 under the action of gravity and flow out through the through hole 3012 opened in the middle of the base plate 3011, avoiding water stagnation on the base plate 3011 and affecting the user experience of the washing equipment.

[0140] like Figure 16 As shown in the figure, the MN direction is the front-to-back direction of the dispensing device. The dispensing cavity 302 has a front opening to facilitate the installation of parts installed inside the dispensing cavity 302. Parts such as the water distribution plate 309 and drawer 303 installed inside the dispensing cavity 302 can be installed through the front opening of the dispensing cavity 302, making installation more convenient. In addition, when the water flow rate is large, the front opening of the dispensing cavity 302 can also dispense a portion of the water flow outside the dispensing cavity 302 to increase the dispensing speed of the water flow.

[0141] To prevent water from stagnating at the rear of the base plate 3011, the middle section of the base plate 3011 gradually extends downwards from back to front. This allows the water to flow towards the front of the base plate 3011 under gravity and exit through the through-hole 3012 and the opening at the front, preventing water from stagnating on the base plate 3011 and affecting the user experience of the washing equipment. Furthermore, the downward extension of the middle section of the base plate 3011 also allows water to converge at the opening at the front of the dispensing chamber 302 when the water flow rate is high, enabling water to be dispensed through the opening and increasing the dispensing speed.

[0142] like Figure 15As shown, the nozzle assembly 300 also includes a drawer 303. Within the nozzle body 301, the treatment agent and water are first added to the drawer 303, and after mixing in the drawer 303, they enter the dispensing chamber 302. Specifically, the drawer 303 is movably disposed within the dispensing chamber 302 between an open position and a closed position. In some embodiments, the user can directly add the treatment agent to the drawer 303 when it is in the open position, and after adding the treatment agent, move the drawer 303 back to the closed position so that the treatment agent can mix with the water and enter the washing equipment.

[0143] Drawer 303 defines a dissolving chamber 304. The treatment agent and water are first added into the dissolving chamber 304. The treatment agent mixes and dissolves with the water in the dissolving chamber 304 and flows out of the dissolving chamber 304 with the water, entering the dispensing chamber 302. After further mixing and dissolving in the dispensing chamber 302, it enters the washing equipment through the through hole 3012 opened on the bottom wall of the dispensing chamber 302. At this time, the treatment agent and water in the washing equipment are mixed more evenly, resulting in a better washing effect of the washing equipment.

[0144] Furthermore, when drawer 303 is in the closed position, such as Figure 7 and Figure 8 As shown, drawer 303 is spaced apart from bottom plate 3011 so that dispensing chamber 302 connects to through hole 3012 and liquid outlet 3041 of dissolving chamber 304. Since the liquid outlet 3041 of dissolving chamber 304 is located at the bottom of drawer 303, the separation between drawer 303 and bottom plate 3011 prevents bottom plate 3011 from blocking the liquid outlet 3041 of dissolving chamber 304, ensuring that liquid in dissolving chamber 304 can stably enter dispensing chamber 302.

[0145] Furthermore, when drawer 303 is in the closed position, drawer 303 is separated from bottom plate 3011. That is, when drawer 303 is in the closed position, drawer 303 is located above dispensing chamber 302, while the lower part of dispensing chamber 302 is an open space. In other words, dispensing chamber 302 is divided into upper and lower spaces by drawer 303. This avoids direct connection between liquid outlet 3041 and one or more through holes 3012, preventing liquid discharged from liquid outlet 3041 from flowing directly out of one or more through holes 3012. This prevents the multiple through holes 3012 on bottom plate 3011 from playing an effective diversion role, ensuring that the liquid in dissolving chamber 304 can stably enter dispensing chamber 302 and undergo further mixing in dispensing chamber 302 before entering the washing equipment, thus improving the dispensing effect of nozzle assembly 300.

[0146] Furthermore, the outlet 3041 and the through hole 3012 are staggered to prevent the water discharged from the outlet 3041 from flowing directly out through the through hole 3012, which would prevent the multiple through holes 3012 opened on the bottom plate 3011 from playing an effective diversion role.

[0147] The side wall of the dispensing cavity 302 and the drawer 303 each have a guide rail 305 and the other has a guide groove 306 that mates with the guide rail 305.

[0148] Specifically, in some embodiments, such as Figure 18 and Figure 19 As shown, drawer 303 has a guide rail 305, and the side wall of the dispensing cavity 302 has a guide groove 306 that mates with the guide rail 305. Drawer 303 is adapted to be movably mounted on guide groove 306 via guide rail 305, so that drawer 303 can slide along guide groove 306, thereby allowing drawer 303 to be movably disposed within dispensing cavity 302 between open and closed positions.

[0149] Furthermore, the arrangement of the guide rail 305 and the guide groove 306 ensures the stability of the drawer 303's movement, and the guide groove 306 on the side wall of the dispensing cavity 302 can support the guide rail 305 of the drawer 303, so that the drawer 303 is stably installed on the upper part of the dispensing cavity 302, ensuring the stability of the drawer 303's installation.

[0150] In other embodiments, the sidewall of the dispensing cavity 302 has a guide rail 305, and the drawer 303 has a guide groove 306 that mates with the guide rail 305. The drawer 303 is adapted to be movably mounted on the guide rail 305 via the guide groove 306, so that the drawer 303 can slide along the guide rail 305, thereby allowing the drawer 303 to be movably disposed within the dispensing cavity 302 between an open position and a closed position.

[0151] Furthermore, the guide rail 305 and guide groove 306 ensure the stability of the drawer 303's movement, and the guide rail 305 on the side wall of the dispensing cavity 302 can support the drawer 303's guide groove 306, so that the drawer 303 is stably installed on the upper part of the dispensing cavity 302, ensuring the stability of the drawer 303's installation.

[0152] Reference Figure 15 and Figure 16 The nozzle body 301 has a first dispensing hole 307, and the outlet of the dispensing pump 200 is connected to the first dispensing hole 307 so that the first dispensing hole 307 can dispense the treatment agent into the dispensing chamber 302. Furthermore, the first dispensing hole 307 is opened on the top wall of the dispensing chamber 302 so that the treatment agent can enter the dispensing chamber 302 by gravity.

[0153] Furthermore, a valve assembly 400 is provided at the first dispensing hole 307. The opening and closing of the first dispensing hole 307 can be controlled by the control assembly 400. By controlling the opening and closing of the first dispensing hole 307, the amount of treatment agent dispensed can be better controlled, thereby achieving a better dispensing effect.

[0154] Furthermore, the nozzle body 301 has a water inlet that can drain water into the washing equipment. The water inlet is connected to the dispensing chamber 302 so that water can enter the dispensing chamber 302 of the nozzle body 301 through the water inlet.

[0155] like Figure 15 As shown, a water distribution plate 309 is also provided inside the dispensing chamber 302. The water distribution plate 309 can divert the water flow before it enters the dispensing chamber 302, ensuring that the water flows into the dispensing chamber 302 evenly. The water distribution plate 309 and the top wall of the dispensing chamber 302 define a water-receiving cavity 310, which buffers the water flow, slows down the flow rate, and allows the water to flow into the dispensing chamber 302 evenly, thereby making the mixing of water and treatment agent more uniform.

[0156] The water distribution plate 309 has multiple water outlet holes 3091 with relatively small diameters. These holes can divert the water flow before it enters the dispensing chamber 302, ensuring a uniform flow. Both the inlet and outlet holes 3091 are connected to the water storage chamber 310, allowing water entering the washing equipment from the inlet to pass through the water storage chamber 310 and then be diverted by the multiple outlet holes 3091 before entering the dispensing chamber 302. This results in a more uniform and slower flow rate.

[0157] Furthermore, the water distribution plate 309 and the top wall of the dispensing cavity 302 can be connected by multiple fasteners to ensure the fixed installation of the water distribution plate 309.

[0158] Reference Figure 15 The height of the water-containing cavity 310 is much smaller than the height of the dispensing cavity 302, so as to leave more space for the mixing of the treatment agent and the water flow, so as to achieve a better mixing effect between the treatment agent and the water flow.

[0159] Furthermore, the nozzle body 301 has a first injection hole 307 that communicates with the injection chamber 302, and the water distribution plate 309 has an avoidance hole 311 for avoiding the first injection hole. The setting of the avoidance hole 311 on the water distribution plate 309 can ensure that the treatment agent directly enters the injection chamber 302, and prevent the treatment agent from being injected into the water holding chamber 310 and blocking the water outlet hole 3091 opened on the water distribution plate 309.
