[0052] Embodiments of the present invention will be described in detail below. Examples of the embodiments are shown in the accompanying drawings, where 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 only for explaining the present invention and should not be construed as limiting the present invention.

[0053] In the present invention, unless otherwise clearly specified and defined, the first feature being "above" or "below" the second feature may include the first and second features being in direct contact, or may include the first and second features not being in direct contact but being in contact through additional features therebetween. Moreover, the first feature being "above", "over" and "on" the second feature includes the first feature being directly above and obliquely above the second feature, or merely indicating that the first feature has a higher horizontal height than the second feature. The first feature being "below", "under" and "beneath" the second feature includes the first feature being directly below and obliquely below the second feature, or merely indicating that the first feature has a lower horizontal height than the second feature.

[0054] Generally, the assembly errors of the dosing device include the assembly errors of the drive button and the transmission parts. The assembly errors will cause the drive button to shift. Moreover, in the design, for the sake of aesthetic appearance, the assembly clearance of the drive button cannot be designed too large. When the drive button shifts, the drive button will lose part of the assembly clearance, resulting in unilateral force, that is, the clearance between one side of the drive button and the inner wall of the installation channel becomes larger, while the other side of the drive button abuts against the inner wall of the installation channel, so that when pressing the drive button, only one side can be stressed, resulting in the problem of jamming when pressing the drive button and affecting the user experience.

[0055] Therefore, the embodiments of the present invention design a dosing device with the drive button of the transmission part separated. By detachably arranging the drive button of the drive part and the transmission part, the assembly errors (such as the assembly error between the transmission part and the dosing pump) can be concentrated at the mating part between the drive part and the transmission part, avoiding the shift of the drive button and the jamming phenomenon caused by the drive button losing the clearance due to the shift, and improving the user experience of the dosing device.

[0056] Below refer toFigures 1 - 23 Describe the dispensing device 1000 according to an embodiment of the present invention.

[0057] The dispensing device 1000 according to an embodiment of the present invention may include: an exterior member 101, a dispensing pump 200, a driving button 1022, and a transmission member 1027.

[0058] Wherein, an appearance surface 1012 is formed on one side of the exterior member 101. The exterior member 101 has an installation channel 1011, and the driving button 1022 is adapted to be pressed and move along the installation channel 1011. The dispensing pump 200 is used to dispense a treatment agent outward under the pressing of the driving button 1022. The transmission member 1027 is disposed between the dispensing pump 200 and the driving button 1022. Wherein, the transmission member 1027 cooperates with the driving button 1022 so that the transmission member 1027 can move along with the movement of the driving button 1022, and the transmission member 1027 cooperates with the dispensing pump 200 so that the dispensing pump 200 can dispense the treatment agent outward under the pressing of the driving button 1022.

[0059] Wherein, the setting of the installation channel 1011 can play a role in positioning and guiding the movement of the driving button 1022. The driving button 1022 moves in the installation channel 1011 to achieve the purpose of driving the dispensing device 1000.

[0060] As Figure 1 and Figure 2 shown, the driving button 1022 and the transmission member 1027 are detachably arranged. Moreover, there is a degree of freedom of movement between the driving button 1022 and the transmission member 1027, that is, after the driving button 1022 and the transmission member 1027 are assembled on the dispensing device 1000, the transmission member 1027 can be offset relative to the driving button 1022 to offset the assembly error through the offset of the transmission member 1027 relative to the driving button 1022, avoiding jamming caused by unilateral force due to the offset of the driving button 1022 and improving the use experience of the dispensing device 1000.

[0061] Specifically, during the assembly process of the dispensing device 1000, assembly errors exist in: the mating part between the exterior member 101 and the driving button 1022, the mating part between the driving button 1022 and the transmission member 1027, and the mating part between the transmission member 1027 and the dispensing pump 200. Due to the pursuit of aesthetics in the appearance design, the assembly gap between the exterior member 101 and the driving button 1022 should be as small as possible and as uniform as possible. Therefore, the assembly error between the exterior member 101 and the driving button 1022 needs to be controlled within the design requirements. On the other hand, in order to ensure the normal dispensing of the dispensing pump 200, the transmission connection between the transmission member 1027 and the dispensing pump 200 should be as matching as possible. Therefore, the assembly error between the transmission member 1027 and the dispensing pump 200 also needs to be controlled within the design requirements.

[0062] Relative to the mating part between the exterior trim part 101 and the drive button 1022 and the mating part between the transmission part 1027 and the dosing pump 200, the assembly error at the mating part between the drive button 1022 and the transmission part 1027 does not affect the transfer of the pressing force from the drive button 1022 to the transmission part 1027. That is, when there is a misalignment between the drive button 1022 and the transmission part 1027 in the up-down, left-right, and other directions, the pressing force applied to the drive button 1022 will still act within the plane of the movement stroke of the transmission part 1027, and thus will not affect the transmission part 1027 to drive the dosing pump 200 to dispense the treatment agent.

[0063] Therefore, concentrating the final cumulative assembly error at the mating part between the drive button 1022 and the transmission part 1027 will not affect the normal operation of the dosing device 1000. Therefore, by detachably arranging the drive button 1022 and the transmission part 1027, and having a degree of freedom of movement between the drive button 1022 and the transmission part 1027, the cumulative assembly error can be concentrated at the mating part between the drive button 1022 and the transmission part 1027, avoiding large errors at the mating part between the exterior trim part 101 and the drive button 1022 and the mating part between the transmission part 1027 and the dosing pump 200, ensuring that the transmission part 1027 can drive the dosing pump 200 to work properly, avoiding jamming caused by the drive button 1022 shifting and experiencing unilateral force, and improving the user experience of the dosing device 1000.

[0064] According to the dosing device of the embodiment of the present invention, the transmission part 1027 and the drive button 1022 of the dosing device 1000 are detachably arranged, which can concentrate the assembly error at the mating part between the transmission part 1027 and the drive button 1022, avoiding jamming caused by the drive button 1022 shifting and experiencing unilateral force, and improving the user experience of the dosing device 1000.

[0065] As Figure 14 and Figure 15 shown, the installation channel 1011 extends obliquely downward from the appearance surface 1012 towards the inside of the exterior trim part 101. When the drive part 102 is pressed, the drive part 102 is adapted to move obliquely downward towards the inside of the exterior trim part 101 in a direction away from the appearance surface 1012.

[0066] When using the washing equipment, the user can drive the dosing device 1000 by pressing the drive part 102 downward. Since the user can reduce the pressing force by means of gravity when applying pressure downward, it is more ergonomic, making the force application process more comfortable and the operation feeling better.

[0067] In addition, within the limited installation space of the washing device, the driving member 102 moving obliquely downward towards the inside of the exterior member 101 can also increase the stroke of the driving member 102 within the limited installation space. Since the dosage of the treatment agent is related to the stroke of the driving member 102, the longer the stroke, the greater the dosage. Therefore, the obliquely moving driving member 102 achieves a larger dosage of the treatment agent.

[0068] Furthermore, among the driving members 102 with the same movement stroke, the driving member 102 moving obliquely downward towards the inside of the exterior member 101 has a smaller displacement in the vertical direction. Thus, it is possible to avoid phenomena such as pinching hands during operation, improving the operation experience.

[0069] Refer to Figures 4 - 9 , a mating groove 10221 is provided on one side of the driving button 1022 close to the transmission member. The transmission member 1027 includes a mating plate 10271 that abuts and mates with the mating groove 10221. The mating groove 10221 abuts and mates with the mating plate 10271. The driving button 1022 and the transmission member 1027 are abutted and mated through the mating groove 10221 and the mating plate 10271, enabling the completion of mating transmission when the driving button 1022 is separated from the transmission member 1027. The side wall of the mating groove 10221 can limit the mating plate 10271 to ensure the stability of the setting of the transmission member 1027. When the driving button 1022 is pressed, the bottom wall of the mating groove 10221 can push the mating plate 10271, causing the transmission member 1027 to move along with the movement of the driving button 1022.

[0070] As Figure 8 and Figure 9 shown, the mating groove 10221 extends along the length direction of the driving button 1022, and the shape of the mating plate 10271 matches the shape of the mating groove 10221. The shape of the mating plate 10271 matches the shape of the mating groove 10221, that is to say, the shape of the mating plate 10271 is similar to the shape of the mating groove 10221, so that the mating plate 10271 can be just set in the mating groove 10221, avoiding shaking between the driving button 1022 and the transmission member 1027 and ensuring the stability of the setting of the driving button 1022.

[0071] According to some embodiments of the present invention, in order to ensure that the pressing force applied to the driving button 1022 can be effectively transmitted to the mating plate 10271, avoid the disengagement between the driving button 1022 and the mating plate 10271, and prevent the driving button 1022 from malfunctioning, the ratio of the surface area of the side of the mating plate 10271 opposite to the bottom wall of the mating groove 10221 to the surface area of the bottom wall of the mating groove 10221 is greater than 45%, so as to have sufficient area between the mating plate 10271 and the bottom wall of the mating groove 10221 to transmit the pressing force. Thus, it can be ensured that the pressing force applied to the driving button 1022 can be effectively transmitted to the mating plate 10271, improving the reliability of the dispensing device 1000.

[0072] Further, as Figure 2 shown, the driving button 1022 has a length direction and a width direction. The length direction is the Figure 2 direction shown as A - B in Figure 2 , and the width direction is the Figure 2 direction shown as C - D in Figure 2 . In order to ensure that the pressing force applied to the driving button 1022 can be effectively transmitted to the mating plate 10271, avoid the disengagement between the driving button 1022 and the mating plate 10271, and prevent the driving button 1022 from malfunctioning, the offset of the center of the mating plate 10271 (as shown by the point O' in Figure 2 ) relative to the center of the driving button 1022 (as shown by the point O in Figure 2 ) in the length direction is less than half of the length of the driving button 1022, and the offset of the center of the mating plate 10271 relative to the center of the driving button 1022 in the width direction is less than half of the width of the driving button 1022.

[0073] That is to say, the center of the mating plate 10271 should always be located within the driving button 1022, so that when the driving button 1022 is pressed, the pressing force can always be transmitted to the center of the mating plate 10271. Thus, it is ensured that the pressing force applied to the driving button 1022 can be effectively transmitted to the mating plate 10271, improving the reliability of the dispensing device 1000.

[0074] Further, one end of the mating plate 10271 close to the valve assembly 400 is bent towards the valve assembly 400, and the side of the bent portion close to the valve assembly 400 is a limiting surface 10275. The extending direction of the limiting surface 10275 is the same as the extending direction of the valve assembly 400. When the transmission member 1027 moves downward and obliquely in the direction close to the valve assembly 400, the push rod 4021 of the valve assembly 400 is adapted to move downward under the drive of the driving surface 1025. When the transmission member 1027 moves to the position where the limiting surface 10275 abuts against the push rod 4021, the push rod 4021 is adapted to limit the transmission member 1027, so that the transmission member 1027 cannot continue to move downward and obliquely.

[0075] Referring to Figure 8 and Figure 9 ,a plurality of cooperating ribs 10222 arranged at intervals are provided on the bottom wall of the cooperating groove 10221. The cooperating ribs 10222 can not only strengthen the structure of the driving button 1022 to ensure the structural strength of the driving button 1022, but also prevent the cooperating plate 10271 from directly cooperating with the bottom surface of the cooperating groove 10221 when the cooperating rib 10222 abuts against one side surface of the cooperating plate 10271, which may cause it difficult for misalignment to occur between the driving button 1022 and the transmission member 1027, affecting the effect of the concentrated error at the mating portion between the driving button 1022 and the transmission member 1027.

[0076] Combined with Figures 3 - 6 the embodiment shown, one of the cooperating plate 10271 and the dosing pump 200 has a first limiting rail 202 and the other has a first cooperating portion 10272, and the first limiting rail 202 is slidably mated with the first cooperating portion 10272 to guide the movement of the transmission member 1027 by the cooperation between the first limiting rail 202 and the first cooperating portion 10272, ensuring the stability of the movement of the transmission member 1027.

[0077] Referring to Figures 3 - 6 ,one of the transmission member 1027 and the dosing pump 200 has a second limiting rail 203 and the other has a second cooperating portion 10273, and the second limiting rail 203 is slidably mated with the second cooperating portion 10273. To guide the movement of the transmission member 1027 by the cooperation between the second limiting rail 203 and the second cooperating portion 10273, ensuring the stability of the movement of the transmission member 1027.

[0078] According to some embodiments of the present invention, the dosing pump 200 is provided with a first limiting rail 202, and the first limiting rail 202 guides the movement of the transmission member 1027 on one side of the transmission member 1027 in cooperation with the first cooperating portion 10272 provided on one side of the transmission member. The dosing pump 200 is further provided with a second limiting rail 203, and the second limiting rail 203 guides the movement of the transmission member 1027 on the other side of the transmission member 1027 in cooperation with the second cooperating portion 10273. Thus, the first limiting rail 202 and the second limiting rail 203 can jointly guide the transmission member 1027 on both sides of the transmission member 1027, further ensuring the stability of the movement of the transmission member 1027. And it can also play a supporting role for the transmission member 1027, further ensuring the stability of the arrangement of the transmission member 1027.

[0079] Referring to Figure 1 、 Figure 4 and Figure 14, according to some embodiments of the present invention, a first reset member 1031 is provided between the transmission member 1027 and the dispensing pump 200 to drive the driving button 1022 to move towards the initial position. The first reset member 1031 can provide a reset force to the driving button 1022 and the transmission member 1027 when the driving button 1022 and the transmission member 1027 move to the limit position, so that the driving button 1022 and the transmission member 1027 return to the initial position.

[0080] As Figure 5 shown, wherein, a positioning portion 1026 is provided on the side of the transmission member 1027 facing away from the driving button 1022, and one end of the first reset member 1031 is engaged with the positioning portion 1026, so that the first reset member 1031 can be stably arranged between the transmission member 1027 and the dispensing pump 200 to achieve stable reset.

[0081] Specifically, the first reset member 1031 is connected to the transmission member 1027, one end of the first reset member 1031 is engaged with the positioning portion 1026 of the transmission member 1027, and the other end of the first reset member 1031 is fixedly arranged with the dispensing pump 200. When the driving button 1022 is pressed, the driving button 1022 and the transmission member 1027 are adapted to move obliquely downward from the initial position and compress the first reset member 1031, so that the first reset member 1031 has a reset force. After the driving button 1022 and the transmission member 1027 move to the limit position, the pressing force applied to the driving button 1022 disappears. At this time, the first reset member 1031 is adapted to apply a reset force to the transmission member 1027 to drive the driving button 1022 and the transmission member 1027 to move towards the initial position, so that the driving button 1022 and the transmission member 1027 are reset.

[0082] Wherein, the positioning portion forms a positioning groove or a positioning post to achieve a better positioning effect.

[0083] Referring to Figures 3 - 6 , the transmission member 1027 has an anti - detachment buckle 10274, and the transmission member 1027 is engaged with the dispensing pump 200 through the anti - detachment buckle 10274 to prevent the transmission member 1027 from detaching from the dispensing pump 200 and improve the overall reliability of the dispensing device 1000.

[0084] As Figure 1 and Figure 13 shown, the dispensing device 1000 further includes: a nozzle body 301, the nozzle body 301 has a dispensing cavity 302. Specifically, a dispensing cavity 302 is defined in the nozzle body 301, and the mixed liquid of water flow and treatment agent can be collected in the dispensing cavity 302 and be fully mixed in the dispensing cavity 302 and then dispensed into the washing device. The setting of the nozzle body 301 can make the mixing of the treatment agent and the water flow more sufficient and make the washing effect of the washing device better.

[0085] Further, a first treatment agent injection hole 307 communicating with the injection chamber 302 is formed in the nozzle body 301. The treatment agent can enter the injection chamber 302 through the first treatment agent injection hole 307, mix with the water flow, and enter the washing device. The injection pump 200 can pump out the treatment agent outward when driven by an external force. Among them, the outlet 201 of the injection pump 200 is communicated with the first treatment agent injection hole 307 to inject the treatment agent into the injection chamber 302. That is to say, the injection pump 200 can inject the treatment agent into the injection chamber 302 of the nozzle body 301 through the first treatment agent injection hole 307, so that the treatment agent can be injected into the washing device.

[0086] Combined Figure 14 with Figure 15 the embodiment shown, an exterior component 101 is provided at the top of the nozzle body 301. Further, the exterior component 101 and the nozzle body 301 cooperate with each other, and the stability of the exterior component can be improved by using the nozzle body 301, so that the overall structure of the dosing device 1000 is more stable and the reliability of the overall setting of the dosing device 1000 is ensured.

[0087] Referring Figure 14 , the outlet 201 of the injection pump 200 is located above the first treatment agent injection hole 307, so that the treatment agent injected by the injection pump 200 can flow downward under the action of gravity and enter the injection chamber 302 through the first treatment agent injection hole 307, avoiding the treatment agent staying in the dosing device 1000.

[0088] Referring Figure 14 , the dosing device 1000 further includes: a valve assembly 400, which is movably arranged at the first treatment agent injection hole 307 for opening or closing the first treatment agent injection hole 307. By controlling the movement of the valve assembly 400 at the first treatment agent injection hole 307, the opening and closing of the first treatment agent injection hole 307 can be controlled. Thus, by controlling the opening and closing of the first treatment agent injection hole 307, the dosing amount of the treatment agent can be better controlled, and a better dosing effect can be achieved.

[0089] The drive button 1022 cooperates with the valve assembly 400 through the transmission member 1027 to control the operation of the injection pump 200 while driving the valve assembly 400 to open the first treatment agent injection hole 307.

[0090] Specifically, when the driving button 1022 is pressed, the mating groove 10221 of the driving button 1022 can be in abutting cooperation with the mating plate 10271 of the transmission member 1027, driving the transmission member 1027 to move obliquely downward in the direction close to the valve assembly 400. When the transmission member 1027 moves obliquely downward in the direction close to the valve assembly 400, the push rod 4021 of the valve assembly 400 is adapted to move downward under the drive of the driving surface 1025 of the transmission member 1027 to open the first treatment agent injection hole 307. At the same time, when the transmission member 1027 moves obliquely downward in the direction close to the valve assembly 400, the transmission member 1027 also cooperates with the injection pump 200 to drive the injection pump 200 to inject the treatment agent outward. Thus, the driving button 1022 can control the injection pump 200 and the valve assembly 400 simultaneously through the transmission member 1027.

[0091] When the driving button 1022 is pressed, it drives the transmission member 1027 to move. The transmission member 1027 can cooperate with the valve assembly 400 and the injection pump 200 respectively. When the driving button 1022 is pressed, while the transmission member 1027 moves, it can drive the valve assembly 400 to open the first treatment agent injection hole 307 and drive the injection pump 200 to pump out the treatment agent outward. In other words, the driving button 1022 can control the operation of the injection pump 200 while driving the valve assembly 400 to open the first treatment agent injection hole 307. The treatment agent pumped out by the injection pump 200 can directly enter the injection chamber 302 through the opened first treatment agent injection hole 307, realizing the injection of the treatment agent.

[0092] That is to say, by pressing the driving button 1022, the valve assembly 400 and the injection pump 200 can be driven to work together, reducing the number of driving structures in the injection device 1000, making the overall structure of the injection device 1000 simpler, reducing the manufacturing cost. And because the valve assembly 400 and the injection pump 200 work simultaneously, the valve assembly 400 will open the first treatment agent injection hole 307 only when the treatment agent needs to be injected, avoiding the leakage of the injection device 1000 and making the whole device more reliable.

[0093] As Figure 14 shown, the driving button 1022 and the transmission member 1027 are arranged above the valve assembly 400, so that the driving button 1022 and the transmission member 1027 are arranged closer to the upper part, making it more convenient for the user to control the injection device 1000 through the driving button 1022 and the transmission member 1027.

[0094] The driving button 1022 and the transmission member 1027 are adapted to move in a diagonally downward direction, so as to drive the valve assembly 400 and the dosing pump 200, enabling the user to drive the driving button 1022 and the transmission member 1027 by applying pressure diagonally downward. Since the user can utilize gravity when applying pressure diagonally downward, it is more ergonomic, making the force application process more comfortable and the operation feel better.

[0095] In the embodiment of the present invention, only by pressing the driving button 1022 and the transmission member 1027 diagonally downward can the dosing of the treatment agent be achieved. There is no need to use an electric dosing pump, which further saves the manufacturing cost of the washing equipment and is more convenient for the user to control the dosing amount of the treatment agent, improving the user experience.

[0096] In some embodiments, the transmission member 1027 includes a rack mechanism. As Figure 2 shown, a rack 1024 is provided on the transmission member 1027, and a gear is provided inside the dosing pump 200. The rack 1024 provided on the transmission member 1027 can cooperate with the gear inside the dosing pump 200 for transmission, so that the dosing pump 200 can operate under the drive of the transmission member 1027 to achieve the dosing of the treatment agent.

[0097] In other embodiments, the transmission member 1027 includes a worm and worm gear mechanism. Of course, the transmission member 1027 can also be other types of transmission mechanisms, which are not limited herein.

[0098] As Figure 17 shown, according to some embodiments of the present invention, the valve assembly 400 includes: a movable valve plate 401 for opening and closing the first treatment agent dosing hole 307. By controlling the movement of the valve plate 401, the opening and closing of the first treatment agent dosing hole 307 can be controlled. To ensure the sealing effect of the valve plate 401 on the first treatment agent dosing hole 307, the diameter of the valve plate 401 is larger than the diameter of the first treatment agent dosing hole 307. Specifically, the valve plate 401 is located below the first treatment agent dosing hole 307, so as to avoid the dosing pump 200. The valve assembly 400 controls the opening and closing of the first treatment agent dosing hole 307 through up and down movement. The first treatment agent dosing hole 307 can be opened when the valve plate 401 moves downward, and the first treatment agent dosing hole 307 can be closed when the valve plate 401 moves upward.

[0099] In some embodiments, the valve assembly 400 further includes a pushing member 402. The pushing member 402 is connected to the valve plate 401, and the pushing member 402 can move under the drive of the driving member 102, thereby driving the valve plate 401 to move.

[0100] Specifically, one end of the pusher 402 can pass through the nozzle body 301, so as to be connected to the valve piece 401 located below the first treatment agent injection hole 307. The other end of the pusher 402 can cooperate with the driving surface 1025 of the driving component 102, so that the driving component 102 can drive the pusher 402 to move downward, and drive the valve piece 401 to move, so as to open and close the first treatment agent injection hole 307.

[0101] According to some embodiments of the present invention, referring to Figure 14 , the transmission member 1027 has a driving surface 1025, and the driving surface 1025 can be slidably matched with the valve assembly 400. During the movement of the transmission member 1027, the driving surface 1025 will also move simultaneously, and the moving direction of the driving surface 1025 is inclined with respect to the valve assembly 400.

[0102] Thus, when the moving direction of the driving surface 1025 is different from the moving direction of the valve assembly 400, the driving surface 1025 can transfer the movement tendency of the transmission member 1027 in the movement direction of the valve assembly 400 to the valve assembly 400, so as to realize the driving of the valve assembly 400 by the transmission member 1027.

[0103] As Figure 13 and Figure 14 shown, according to some embodiments of the present invention, the valve assembly 400 is movable in the up and down direction, and the driving surface 1025 extends downward obliquely in the direction close to the valve assembly 400. Thus, the driving surface 1025 can convert the obliquely downward movement tendency of the transmission member 1027 into the downward movement tendency of the valve assembly 400, and push the valve assembly 400 to move downward, so as to control the opening and closing of the first treatment agent injection hole 307 by controlling the movement of the valve assembly 400.

[0104] Moreover, the driving surface 1025 extends downward obliquely in the direction close to the valve assembly 400, which can avoid the valve assembly 400 being subjected to lateral pressure, resulting in bending of the valve assembly 400 and affecting the reliability of the movement of the valve assembly 400.

[0105] Referring to Figure 14 , the driving surface 1025 is inclined with respect to the moving direction of the transmission member 1027, so that the driving surface 1025 can convert the obliquely downward movement tendency of the transmission member 1027 into the downward movement tendency of the valve assembly 400, and push the valve assembly 400 to move downward, so as to control the opening and closing of the first treatment agent injection hole 307 by controlling the movement of the valve assembly 400.

[0106] As Figure 17As shown, in some embodiments, the nozzle body 301 has a mounting hole 3013, and the valve assembly 400 is inserted through the mounting hole 3013. A second reset member 1032 is provided between the valve assembly 400 and the nozzle body 301 to drive the valve assembly 400 to close the first treatment agent injection hole 307. In some embodiments, the nozzle body 301 has a mounting hole 3013, and the pusher 402 is inserted through the mounting hole 3013 so that the pusher 402 can be connected to the valve plate 401 located below the first treatment agent injection hole 307.

[0107] Combined with Figure 1 Looking further, a second reset member 1032 is provided between the pusher 402 and the nozzle body 301 to drive the pusher 402 to drive the valve plate 401 to close the first treatment agent injection hole 307. That is to say, the transmission member 1027 is reset under the action of the first reset member 1031. During the reset process, the transmission member 1027 gradually cancels the acting force on the pusher 402, and the second reset member 1032 can provide a reset force for the pusher 402 to drive the pusher 402 to drive the valve plate 401 back to the position of closing the first treatment agent injection hole 307.

[0108] Specifically, one end of the second reset member 1032 cooperates with the pusher 402, and the other end of the second reset member 1032 cooperates with the nozzle body 301. When the pusher 402 is subjected to the downward pressure of the transmission member 1027, the pusher 402 and the valve plate 401 connected thereto are adapted to move downward from the position of closing the first treatment agent injection hole 307 and compress the second reset member 1032, so that the second reset member 1032 has a reset force. When the transmission member 1027 gradually cancels the downward acting force on the pusher 402, the reset force exerted by the second reset member 1032 on the pusher 402 can drive the pusher 402 and the valve plate 401 to move to the position of closing the first treatment agent injection hole 307.

[0109] Referring to Figure 17 , in some embodiments, the pusher 402 includes: a push rod 4021 and a mounting seat 4022. One end of the push rod 4021 extends out of the nozzle body 301 to cooperate with the transmission member 1027, and the other end of the push rod 4021 extends into the nozzle body 301. The mounting seat 4022 is arranged in the nozzle body 301, and the middle part of the mounting seat 4022 is detachably connected to the other end of the push rod 4021. For example, the mounting seat 4022 and the other end of the push rod 4021 can be in threaded cooperation. A fixing post is provided at a position deviating from the middle of the mounting seat 4022, and the valve plate 401 cooperates with the fixing post.

[0110] In some specific examples, the second reset member 1032 forms a spring. The spring is sleeved on the push rod 4021. One end of the spring abuts against the mounting seat 4022 and the other end abuts against the nozzle body 301. The structure is simple and the installation and disassembly are convenient.

[0111] A specific embodiment of the delivery device 1000 according to the present invention is described below with reference to the accompanying drawings.

[0112] like Figure 1 and Figure 13 As shown, the delivery device 1000 includes: a driving assembly 100, a delivery pump 200, a nozzle assembly 300 and a valve assembly 400. The driving assembly 100 includes: an exterior component 101 and a driving component 102. The driving component 102 is movably arranged on the exterior component 101. The driving component 102 includes a driving button 1022 and a transmission member 1027 that can be detachably stopped and matched. The transmission member 1027 is respectively matched with the delivery pump 200 and the valve assembly 400. The user can simultaneously drive the valve assembly 400 and the delivery pump 200 by pressing the driving button 1022 in the driving assembly 100 to deliver the treatment agent into the nozzle assembly 300, thereby realizing one-key delivery of the treatment agent.

[0113] like Figure 13 As shown, the exterior component 101 has an installation channel 1011. The installation channel 1011 can play a role in positioning and guiding the movement of the driving component 102. The driving component 102 moves in the installation channel 1011 to achieve the purpose of driving the delivery device 1000. Further, the driving component 102 is movably arranged in the installation channel 1011 between a first position and a second position, that is, the driving component 102 can be limited by the exterior component 101 at the first position and the second position to prevent the driving component 102 from being separated from the installation channel 1011, and when the driving component 102 moves between the first position and the second position of the installation channel 1011, the delivery device 1000 is driven to deliver.

[0114] Furthermore, the first position is located outside the second position in the extension direction of the installation channel 1011, that is, when the driving assembly 100 is in a natural state, the driving component 102 is located at the first position outside the installation channel 1011, and when the user needs to drive the delivery device 1000 through the driving assembly 100, the user presses the driving component 102 to move the driving component 102 inward along the installation channel 1011 until it moves to the second position. At the second position, the driving component 102 is limited, and the user cannot continue to apply pressure inward to make the driving component 102 continue to move inward.

[0115] Among them, the gap between the driving component 102 and the wall surface of the installation channel 1011 gradually increases from the outside to the inside as the driving component 102 moves. Since the distance of the gap between the driving component 102 and the wall surface gradually becomes larger during the movement, when the user presses the driving component 102, during the pressing process, as the driving component 102 moves, the distance between the driving component 102 and the wall surface becomes larger and larger. Therefore, when the driving component 102 is offset, since the distance of the gap between the driving component 102 and the wall surface can be greater than the offset amount of the driving component 102 during the movement, there can always be a gap between the driving component 102 and the wall surface to enable the driving component 102 to move inward smoothly.

[0116] Thus, by increasing the distance between the inside of the installation channel 1011 and the driving component 102, the movement process of the driving component 102 becomes smoother, improving the operating feel of the driving assembly 100.

[0117] When the user presses the driving component 102, during the pressing process, the movement process of the driving component 102 gradually moving inward becomes smoother, improving the operating feel of the driving component 102. And since the gap between the outermost driving component 102 and the wall surface is the smallest, the aesthetic appearance of the exterior component 101 is ensured.

[0118] Moreover, since the gap between the outermost driving component 102 and the wall surface is set to be small, the relative offset amount of the driving component 102 relative to the exterior component 101 is restricted, making the relative offset amount of the driving component 102 relative to the exterior component 101 small, further ensuring the smoothness of the movement of the driving component 102 in the installation channel 1011 and improving the operating feel.

[0119] As Figure 15 shown, the cross-sectional area of the installation channel 1011 gradually expands in the direction from the outside to the inside. That is to say, the installation channel 1011 presents 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 surface gradually increases. As the gap gradually increases, when the user presses the driving component 102, the movement of the driving component 102 inward during the pressing process becomes smoother, improving the operating feel of the driving component 102.

[0120] Referring to Figure 15 , in the state of the first position, the driving component 102 is in close fit with the wall surface, ensuring that in the natural state, the user cannot observe the gap between the driving component 102 and the exterior component 101 from the appearance, improving the aesthetic appearance.

[0121] Moreover, in the state of the first position, the driving component 102 is in close fit with the wall surface, and the wall surface of the installation channel 1011 can limit the driving component 102 to ensure that the driving component 102 is stably limited in the first position. During the inward movement of the driving component 102, since the cross-sectional area of the installation channel 1011 gradually expands in the direction from outside to inside, the gap between the driving component 102 and the wall surface gradually increases from 0. As the gap gradually increases, when the user presses the driving component 102, the process of the driving component 102 moving inward during the pressing becomes smoother, improving the operating feel of the driving component 102.

[0122] Furthermore, since the driving component 102 is in close fit with the wall surface of the installation channel 1011 in the state of the first position, it is ensured that the relative offset amount of the driving component 102 with respect to the exterior component 101 is small, further ensuring the smoothness of the movement of the driving component 102 in the installation channel 1011 and improving the operating feel.

[0123] Combined with Figure 12 and Figure 15 the illustrated embodiment, in the state of the first position, a part of the driving component 102 protrudes from the outer surface of the exterior component 101. The user presses the part of the driving component 102 that protrudes from the outer surface of the exterior component 101 to move the driving component 102 along the installation channel 1011, thereby making the operation feeling of the driving assembly 100 better and making it more convenient for the user to apply force to the driving component 102.

[0124] As Figure 2 shown, the exterior component 101 includes: an exterior panel 1012. The exterior panel 1012 is located outside the driving assembly 100 and can protect the dispensing device 1000 and the driving assembly 100 on the outside to ensure the running stability of the dispensing device 1000 and the driving assembly 100. The exterior panel 1012 has an opening, and a part of the driving component 102 protrudes outward through the opening to facilitate the user to apply pressure to the driving component 102. A surrounding plate 1013 is provided inside the opening, and the surrounding plate 1013 defines the installation channel 1011. Among them, one end of the surrounding plate 1013 is connected to the edge of the opening to define the installation channel 1011 at the opening. And, the surrounding plate 1013 is located inside the exterior panel 1012 to define the installation channel 1011 inside the opening.

[0125] Furthermore, the surrounding plate 1013 can limit the driving component 102 to ensure the stability of the setting of the driving component 102. And the surrounding plate 1013 can play a guiding role in the movement of the driving component 102 to ensure the stability of the movement process of the driving component 102.

[0126] Combined with Figure 2 andFigure 15 In the illustrated embodiment, the driving component 102 has decorative ribs 1021 extending along its circumferential direction. The decorative ribs 1021 are exposed when the driving component 102 moves towards the inside of the installation channel 1011. Thus, during the process of the driving component 102 moving inwards, the gap between the driving component 102 and the exterior decorative panel 1012 can be avoided being observed from the outside, thereby improving the aesthetic appearance.

[0127] Furthermore, the decorative ribs 1021 cooperate with the wall surface of the installation channel 1011 to ensure the stability of the driving component 102 during the movement process, avoid a large deviation in the position of the driving component 102 during the movement process, and make the movement process smoother.

[0128] Furthermore, at the opening, there is also a limiting rib 1014 protruding from the surrounding plate 1013 to limit the decorative rib 1021. Specifically, at the opening of the exterior decorative panel 1012, a limiting rib 1014 protruding towards the inside of the installation channel 1011 is provided. When the driving component 102 is in the first position, the limiting rib 1014 can cooperate with the decorative rib 1021 to limit the driving component 102 to prevent the driving component 102 from falling off.

[0129] Referring to Figure 15 , the user presses the driving button 1022 to make the driving component 102 move inwards. During the process of the driving component 102 moving inwards, the purpose of driving the dispensing device 1000 to dispense is achieved. The driving button 1022 cooperates with the wall surface of the installation channel 1011. That is to say, the wall surface of the installation channel 1011 limits the driving button 1022 to achieve the purpose of limiting the driving component 102, and the wall surface of the installation channel 1011 guides the movement of the driving button 1022 to achieve the purpose of guiding the movement of the driving component 102.

[0130] Furthermore, the decorative rib 1021 is formed inside the driving button 1022 to limit the entire driving component 102 by limiting the driving button 1022.

[0131] As Figure 18As shown, the nozzle assembly 300 may include: a nozzle body 301. The nozzle body 301 includes a bottom plate 3011. The bottom plate 3011 is located at the bottom of the nozzle body 301, and the bottom plate 3011 forms the bottom wall of the dosing chamber 302. That is to say, after the mixed liquid of water flow and treatment agent converges into the dosing chamber 302, it will flow downward under the action of gravity and be received by the bottom plate 3011 that forms the bottom wall of the dosing chamber 302. And because the bottom plate 3011 is provided with a plurality of through holes 3012 arranged at intervals, and each through hole 3012 communicates with the dosing chamber 302, so that the liquid in the dosing chamber 302 can flow out through the through holes 3012. Thus, the mixed liquid of water flow and treatment agent received on the bottom plate 3011 can flow out through the through holes 3012 opened on the bottom plate 3011, so that the mixed liquid of water flow and treatment agent that is uniformly mixed in the dosing chamber 302 can be dosed into the washing device.

[0132] Further, under the splitting action of the plurality of through holes 3012 arranged at intervals, after the water flow mixed with the treatment agent is split by the plurality of through holes 3012, the water flow is more uniform, and the flow velocity of the water flow decreases, avoiding the phenomenon of liquid splashing caused by the water flow with a larger flow velocity directly impacting the clothes, and improving the user experience.

[0133] As Figure 19 shown, the through holes 3012 form round holes, which is convenient for the processing of the bottom plate 3011 of the nozzle body 301. In some embodiments, the through holes 3012 form square holes. Of course, the through holes 3012 can also be formed into triangular holes or through holes 3012 of other shapes, which are not limited herein.

[0134] Referring to Figure 19 , the through holes 3012 are arranged in the middle of the bottom plate 3011. In order to ensure the connection strength between the bottom plate 3011 and the nozzle body 301, through holes 3012 are not opened at both ends of the bottom plate 3011. In order to prevent the water flow received at both ends of the bottom plate 3011 from staying at both ends of the bottom plate 3011, both ends of the bottom plate 3011 gradually extend downward along the direction close to the middle of the bottom plate 3011. Thus, the water flow received at both ends of the bottom plate 3011 can flow toward the middle of the bottom plate 3011 under the action of gravity and flow out through the through holes 3012 opened in the middle of the bottom plate 3011, avoiding the water flow staying on the bottom plate 3011 and affecting the use experience of the washing device.

[0135] As Figure 20 shown, the dosing chamber 302 has a front side opening, which is convenient for the installation of the parts arranged in the dosing chamber 302. Parts such as the water distribution plate 309 and the drawer 303 arranged in the dosing chamber 302 can be installed through the opening provided on the front side of the dosing chamber 302, making the installation more convenient. And when the water flow rate is large, the opening on the front side of the dosing chamber 302 can also discharge a part of the water flow to the outside of the dosing chamber 302 to improve the dosing speed of the water flow.

[0136] Referring to Figure 19 , the through hole 3012 is provided at the front part of the bottom plate 3011. To ensure the connection strength between the bottom plate 3011 and the nozzle body 301, no through hole 3012 is provided at the rear end of the bottom plate 3011. To prevent the water flow received at the rear end of the bottom plate 3011 from staying at the rear end of the bottom plate 3011, the middle part of the bottom plate 3011 gradually extends downward from the rear to the front. Thus, the water flow received at the rear end of the bottom plate 3011 can flow forward to the front part of the bottom plate 3011 under the action of gravity and flow out through the through hole 3012 provided at the front part of the bottom plate 3011 and the opening at the front part, avoiding the water flow staying on the bottom plate 3011 and affecting the use experience of the washing device.

[0137] Furthermore, the middle part of the bottom plate 3011 gradually extends downward from the rear to the front, and can also make the water flow gather at the opening at the front side of the dosing chamber 302 when the water flow rate is large, so that the opening at the front side of the dosing chamber 302 discharges the water flow to improve the discharging speed of the water flow.

[0138] As Figure 1 and Figure 18 shown, the nozzle assembly 300 of the dosing device 1000 further includes a drawer 303. Inside the nozzle body 301, the treatment agent and the water flow are first put into the drawer 303, and after being mixed in the drawer 303, they enter the dosing chamber 302. Specifically, the drawer 303 is movably provided in the dosing chamber 302 between an open position and a closed position. In some embodiments, the user can directly put the treatment agent into the drawer 303 when the drawer 303 is in the open position, and move the drawer 303 after putting the treatment agent to make the drawer 303 return to the closed position, so that the treatment agent can be mixed with the water flow and enter the washing device.

[0139] Wherein, the drawer 303 defines a treatment agent dissolution chamber 304. The treatment agent and the water flow are first put into the treatment agent dissolution chamber 304. The treatment agent is mixed and dissolved with the water flow in the treatment agent dissolution chamber 304, and flows out of the treatment agent dissolution chamber 304 along with the water flow and enters the dosing chamber 302. After further mixing and dissolution in the dosing chamber 302, it enters the washing device through the through hole 3012 provided on the bottom wall of the dosing chamber 302. At this time, the treatment agent entering the washing device is more evenly mixed with the water flow, making the washing effect of the washing device better.

[0140] Furthermore, when the drawer 303 is in the closed position, as Figure 7 and Figure 8As shown, there is a gap between the drawer 303 and the bottom plate 3011, so that the dosing chamber 302 communicates with the through hole 3012 and the liquid outlet 3041 of the treatment agent dissolution chamber 304. Since the liquid outlet 3041 of the treatment agent dissolution chamber 304 is provided at the bottom of the drawer 303, separating the drawer 303 from the bottom plate 3011 can prevent the bottom plate 3011 from blocking the liquid outlet 3041 of the treatment agent dissolution chamber 304, ensuring that the liquid in the treatment agent dissolution chamber 304 can stably enter the dosing chamber 302.

[0141] Moreover, when the drawer 303 is in the closed position, there is a gap between the drawer 303 and the bottom plate 3011. That is to say, when the drawer 303 is in the closed position, the drawer 303 is located above the dosing chamber 302, and the lower part of the dosing chamber 302 is an open space. In other words, the dosing chamber 302 is divided into upper and lower spaces by the drawer 303, thus preventing the liquid outlet 3041 from directly communicating with one or more through holes 3012, and the liquid discharged from the liquid outlet 3041 directly flowing out from one or some of the through holes 3012, resulting in the multiple through holes 3012 provided on the bottom plate 3011 being unable to play an effective shunting role. This ensures that the liquid in the treatment agent dissolution chamber 304 can stably enter the dosing chamber 302, and after further mixing in the dosing chamber 302, it enters the washing device, improving the dosing effect of the spray head assembly 300.

[0142] Furthermore, the liquid outlet 3041 and the through holes 3012 are staggered to prevent the water flow discharged from the liquid outlet 3041 from directly flowing out through the through holes 3012, resulting in the multiple through holes 3012 provided on the bottom plate 3011 being unable to play an effective shunting role.

[0143] Wherein, one of the side wall of the dosing chamber 302 and the drawer 303 has a guide rail 305 and the other has a guide groove 306 that cooperates with the guide rail 305.

[0144] Specifically, in some embodiments, as Figure 18 and Figure 19 shown, the drawer 303 has a guide rail 305, and the side wall of the dosing chamber 302 has a guide groove 306 that cooperates with the guide rail 305. The drawer 303 is adapted to be movably mounted on the guide groove 306 through the guide rail 305, so that the drawer 303 can slide along the guide groove 306, and further enables the drawer 303 to be movably disposed in the dosing chamber 302 between the open position and the closed position.

[0145] Furthermore, the setting of the guide rail 305 and the guide groove 306 ensures the stability of the movement of the drawer 303, and the guide groove 306 provided on the side wall of the dosing chamber 302 can support the guide rail 305 of the drawer 303, enabling the drawer 303 to be stably mounted on the upper part of the dosing chamber 302, ensuring the stability of the setting of the drawer 303.

[0146] In some other embodiments, the side wall of the dosing chamber 302 has guide rails 305, and the drawer 303 has guide grooves 306 that cooperate with the guide rails 305. The drawer 303 is adapted to be movably mounted on the guide rails 305 through the guide grooves 306, so that the drawer 303 can slide along the guide rails 305, and further, the drawer 303 can be movably disposed within the dosing chamber 302 between an open position and a closed position.

[0147] Furthermore, the arrangement of the guide rails 305 and the guide grooves 306 ensures the stability of the movement of the drawer 303, and the guide rails 305 provided on the side wall of the dosing chamber 302 can support the guide grooves 306 of the drawer 303, enabling the drawer 303 to be stably mounted on the upper part of the dosing chamber 302, ensuring the stability of the setting of the drawer 303.

[0148] Refer to Figure 18 and Figure 19 , the nozzle body 301 has a first treatment agent dosing hole 307, and the first treatment agent dosing hole 307 can dose the treatment agent into the dosing chamber 302. Moreover, the first treatment agent dosing hole 307 is opened on the top wall of the dosing chamber 302, so that the treatment agent can enter the dosing chamber 302 by gravity.

[0149] Furthermore, a valve 308 is provided at the first treatment agent dosing hole 307. By controlling the valve 308, the opening and closing of the first treatment agent dosing hole 307 can be controlled. By controlling the opening and closing of the first treatment agent dosing hole 307, the dosing amount of the treatment agent can be better controlled, achieving a better dosing effect of the treatment agent.

[0150] Furthermore, the nozzle body 301 has a water inlet hole, and the water inlet can drain water into the washing device. The water inlet hole communicates with the dosing chamber 302, so that water can enter the dosing chamber 302 of the nozzle body 301 through the water inlet.

[0151] As Figure 16 shown, a water distribution plate 309 is further provided in the dosing chamber 302. The water distribution plate 309 can first split the water flow before the water flow enters the dosing chamber 302, ensuring that the water flow evenly enters the dosing chamber 302. The water distribution plate 309 and the top wall of the dosing chamber 302 define a water storage chamber 310 to buffer the water flow by using the water storage chamber 310, slowing down the flow rate of the water flow, so that the water flow can evenly enter the dosing chamber 302, and further making the mixing of the water flow and the treatment agent more uniform.

[0152] Among them, a plurality of water outlet holes 3091 are formed in the water diversion plate 309, and the apertures of the plurality of water outlet holes 3091 are set to be relatively small, which can divert the water flow before the water flow enters the dosing chamber 302 to ensure that the water flow evenly enters the dosing chamber 302. Both the water inlet hole and the water outlet holes 3091 are communicated with the water containing chamber 310, so that the water flow entering the washing device from the water inlet can pass through the water containing chamber 310, and after being diverted by the plurality of water outlet holes 3091, it enters the dosing chamber 302, so that the water flow is more uniform and the flow rate is slower.

[0153] Referring to Figure 16 , the water diversion plate 309 and the top wall of the dosing chamber 302 can be connected by a plurality of fasteners to ensure the fixed installation of the water diversion plate 309.

[0154] Furthermore, referring to Figure 16 , the height of the water containing chamber 310 is much smaller than the height of the dosing chamber 302, so as to leave more space for the mixing of the treatment agent and the water flow, so that the mixing effect of the treatment agent and the water flow is better.

[0155] Combined with Figure 19 , Figure 22 and Figure 23 As shown in the illustrated embodiment, the nozzle body 301 has a first treatment agent dosing hole 307 communicated with the dosing chamber 302, and the water diversion plate 309 has an avoidance hole 311 for avoiding the first washing dosing hole. The setting of the avoidance hole 311 on the water diversion plate 309 can ensure that the treatment agent directly enters the dosing chamber 302, and prevent the treatment agent from being dosed into the water containing chamber 310 and blocking the water outlet holes 3091 formed on the water diversion plate 309.
