[0053] Embodiments of the present invention are described in detail below, examples of which are shown in the accompanying drawings, wherein the same or similar reference numerals throughout represent the same or similar elements or elements having the same or similar functions. The embodiments described below with reference to the accompanying drawings are exemplary and are intended to be used to explain the present invention, and should not be construed as limiting the present invention.

[0054] The disclosure below provides many different embodiments or examples to implement different structures of the present invention. In order to simplify the disclosure of the present invention, the parts and settings of specific examples are described below. Of course, they are only examples, and the purpose is not to limit the present invention. In addition, the present invention can repeat reference numbers and / or letters in different examples. This repetition is for the purpose of simplicity and clarity, and does not itself indicate the relationship between the various embodiments and / or settings discussed. In addition, the present invention provides various specific processes and examples of materials, but those of ordinary skill in the art can be aware of the applicability of other processes and / or the use of other materials.

[0055] The following is a description of the dispensing device 10, dispensing assembly 100 and washing equipment 1000 according to an embodiment of the present invention. For example, the dispensing device 10 can be used in washing devices with water inlet systems such as washing machines, dishwashers, sinks or wash basins.

[0056] Reference Figure 1 and Figure 2 As shown, the dispensing device 10 according to an embodiment of the present invention is used for dispensing detergent and may include: a dispensing pump 1, a driving component 2 and a valve 4. The detergent may be liquid detergent such as laundry detergent and softener.

[0057] Reference Figure 3-Figure 5 As shown, the dosing pump 1 includes a pump housing 11 and a pump body 12. The pump body 12 is movably disposed in the pump housing 11. The pump housing 11 is formed with a liquid inlet 116 and a liquid outlet 117. The drive assembly 2 includes a movable drive member 21, which can drive the pump body 12 to move. The valve 4 is used to open and close the liquid outlet 117 (refer to Figure 6 and Figure 7 ), the valve 4 is connected to the driving member 21, and the movement of the driving member 21 can drive the valve 4 to move to open the liquid outlet 117. Optionally, the user can manually drive the driving member 21 to move to open the liquid outlet 117, thereby achieving the delivery of lotion.

[0058] For example, refer to Figure 1 and Figure 6 As shown, the valve 4 is arranged on the driving member 21. When no external force acts on the driving member 21, the valve 4 closes the liquid outlet 117. When the user manually rotates the driving member 21 (refer to Figure 7 ), the driving member 21 drives the valve 4 to rotate to open the liquid outlet 117, and at the same time, the driving member 21 drives the pump body 12 to rotate, sucking the lotion from the liquid inlet 116 and discharging it from the liquid outlet 117, so as to achieve the delivery of the lotion. Therefore, when the delivery pump 1 does not deliver the lotion, the liquid outlet 117 can be kept in a closed state, which can effectively prevent the residual liquid from drying, solidifying, oxidizing and other problems, and can also reduce the sealing requirements of the pump body 12 in the delivery device 10, and is conducive to simplifying the structure of the delivery device 10, reducing the manufacturing difficulty, saving costs, and at the same time not increasing the user's operating difficulty.

[0059] Of course, the present invention is not limited to this. The driving member 21 can also be movably arranged on the shell. When there is no external force acting on the driving member 21, the valve 4 closes the liquid outlet 117. When the user manually moves the driving member 21, the driving member 21 drives the valve 4 to move to open the liquid outlet 117. At the same time, the driving member 21 drives the pump body 12 to move, suck the lotion from the liquid inlet 116 and discharge it from the liquid outlet 117 to achieve the delivery of the lotion.

[0060] In view of this, according to the dispensing device 10 of the embodiment of the present invention, by providing a valve 4 for opening and closing the liquid outlet 117, when no external force acts on the driving member 21, the valve 4 closes the liquid outlet 117, and when the user manually drives the driving member 21 to move, the driving member 21 drives the valve 4 to move to open the liquid outlet 117. At the same time, the driving member 21 drives the pump body 12 to move, and the lotion is sucked from the liquid inlet 116 and discharged from the liquid outlet 117 to achieve the dispensing of the lotion. Therefore, when the dispensing pump 1 does not dispense lotion, the liquid outlet 117 can be kept in a closed state, which can effectively prevent the residual liquid from drying up, solidifying, oxidizing and other problems, and can also reduce the sealing requirements of the pump body 12 in the dispensing device 10, and is conducive to simplifying the structure of the dispensing device 10, reducing the manufacturing difficulty, saving costs, and at the same time does not increase the user's operating difficulty.

[0061] In some embodiments of the present invention, reference Figure 1 and Figure 6 As shown, the pump housing 11 includes a housing body 1111 and a liquid discharge portion 1112. The pump body 12 is located in the housing body 1111. The liquid discharge portion 1112 protrudes outward from the housing body 1111. The liquid discharge portion 1112 is formed with a liquid outlet 117. The valve 4 and the liquid discharge portion 1112 are arranged opposite to each other in the movement direction of the valve 4. Therefore, when the driving member 21 is located in the first position, the valve 4 cooperates with a side wall of the liquid discharge portion 1112, so that the valve 4 can reliably close the liquid outlet 117, which is conducive to preventing the delivery device 10 from leaking.

[0062] For example, in some examples, refer to Figure 1 and Figure 6 As shown, a pump chamber 113 is defined in the housing body 1111, the pump body 12 is located in the pump chamber 113, the discharge portion 1112 protrudes from the housing body 1111, the discharge portion 1112 has a flow channel 1113 connected to the pump chamber 113, the liquid outlet 117 is provided on one side wall of the discharge portion 1112 and is connected to the flow channel 1113, when the driving member 21 is located in the first position, the valve 4 cooperates with one side wall of the discharge portion 1112 (refer to Figure 6 Thus, when the driving member 21 is located at the first position, the valve 4 cooperates with the side wall of the discharge portion 1112 to ensure that the valve 4 can reliably close the liquid outlet 117, which is beneficial to prevent the delivery device 10 from leaking.

[0063] In some embodiments of the present invention, reference Figure 6As shown, when the valve 4 closes the liquid outlet 117, at least a portion of the valve 4 fits into the liquid outlet 117. In other words, a portion of the valve 4 may fit into the liquid outlet 117, or the entire valve 4 may be located in the liquid outlet 117. Thus, when the valve 4 closes the liquid outlet 117, the sealing effect of the valve 4 on the liquid outlet 117 is improved, which helps prevent the lotion from leaking.

[0064] Optionally, in some examples, reference Figure 6 and Figure 7 As shown, the valve 4 includes a main body 41 and a sealing part 42 connected to each other. When the valve 4 closes the liquid outlet 117, the sealing part 42 cooperates with the liquid outlet 117. The driving assembly 2 includes a pushing part 214, wherein one end of the pushing part 214 is connected to the driving member 21, and the other end of the pushing part 214 is connected to the main body 41. For example, the other end of the pushing part 214 can be directly connected to the main body 41 or indirectly connected.

[0065] It can be understood that the movement of the driving member 21 can drive the pushing portion 214 to move, the movement of the pushing portion 214 can drive the main body 41 to move, and the movement of the main body 41 can drive the sealing portion 42 to move. When the driving member closes the liquid outlet 117 of the valve 4, the sealing portion 42 cooperates with the liquid outlet 117 to achieve sealing of the liquid outlet 117, which is beneficial to ensure the reliability of the sealing cooperation between the sealing portion 42 and the inner wall of the liquid outlet 117, and the other end of the pushing portion 214 is connected to the main body 41, with a simple structure and easy operation.

[0066] In some optional embodiments of the present invention, referring to Figure 6 As shown, the push part 214 is integrally formed with the main body 41. It is understandable that the integrally formed structure can not only ensure the structural and performance stability of the push part 214 and the main body 41, but also facilitate molding and simplify manufacturing, and eliminate unnecessary assembly parts and connection processes, greatly improving the assembly efficiency of the push part 214 and the main body 41, ensuring the reliability of the connection between the push part 214 and the main body 41, and furthermore, the integrally formed structure has higher overall strength and stability, is more convenient to assemble, and has a longer service life. Further, in some examples, the main body 41 is integrally formed with the entire valve 4.

[0067] In some optional embodiments of the present invention, referring to Fig. 9As shown, the push portion 214 is separately provided with the main body 41, and the push portion 214 is meshedly connected with the main body 41. For example, the other end of the push portion 214 can be meshedly connected with the main body 41 and contacted with it. It can be understood that by making the push portion 214 and the main body 41 separately provided, it is helpful to reduce the difficulty of mold opening of the push portion 214 and the main body 41, which is helpful to reduce the mold opening cost. At the same time, by making the push portion 214 and the main body 41 meshedly connected, it is helpful to improve the reliability of the cooperation between the push portion 214 and the main body 41.

[0068] In some specific examples of the present invention, referring to Fig. 9 As shown, a first step 213 is provided on one side of the push portion 214 close to the main body 41, and a second step 43 is provided on one side of the main body 41 close to the push portion 214, and the first step 213 is meshed and connected with the second step 43. Fig. 9 As shown, the upper end of the push portion 214 is connected to the connecting portion 212 of the driving member 21, and the lower end of the push portion 214 is formed with a first step 213 in a step shape, and the first step 213 is engaged with the second step 43. It can be understood that the engagement of the first step 213 with the second step 43 is conducive to ensuring that the driving member 21 can reliably drive the valve 4 to move, thereby ensuring that the valve 4 can reliably open or close the liquid outlet 117, and the structure is simple and the production cost is low.

[0069] In some specific examples of the present invention, referring to Fig. 9 As shown, a stopper 118 is provided on the pump housing 11, and a second elastic reset member 5 is provided between the stopper 118 and the main body 41, and the second elastic reset member 5 is used to drive the valve 4 to reset to the position of closing the liquid outlet 117; wherein, one end of the second elastic reset member 5 is connected to the side of the main body 41 away from the liquid outlet 117, and the other end of the second elastic reset member 5 is connected to the side of the stopper 118 facing the liquid outlet 117. For example, the second elastic reset member 5 can be a spring. It is understandable that the second elastic reset member 5 is connected between the valve 4 and the stopper 118 to always push the valve 4 to move in the direction of closing the liquid outlet 117, which is conducive to ensuring that when the driving member 21 is in the position of closing the liquid outlet 117, the valve 4 can reliably close the liquid outlet 117.

[0070] In some optional examples of the present invention, reference Fig. 9 As shown, the pump housing 11 is provided with a guide structure 6, wherein the guide structure 6 is located between the stopper 118 and the main body 41, and the guide structure 6 extends along the contraction direction of the second elastic reset member 5. Fig. 9As shown, there are two guide structures 6 arranged in parallel and spaced apart in the up-down direction, each guide structure 6 extends in the front-to-back direction, and the valve 4 is slidably matched with the guide structure 6 along the front-to-back direction. It can be understood that by setting the valve 4 to extend along the contraction direction of the second elastic reset member 5, and the valve 4 is slidably matched with the guide structure 6, the movement trajectory of the valve 4 can be made reliable, which is conducive to ensuring that the valve 4 reliably opens or closes the liquid outlet 117.

[0071] In some optional embodiments of the present invention, referring to Figure 6 As shown, the sealing portion 42 is arranged opposite to the liquid outlet 117, the sealing portion 42 has a first trapezoidal cross section, and the liquid outlet 117 has a second trapezoidal cross section, and the first trapezoidal cross section and the second trapezoidal cross section are interference fit. The first trapezoidal cross section is the cross section of the sealing portion 42, and the second trapezoidal cross section is the cross section of the liquid outlet 117. For example, Figure 6 As shown, the first trapezoidal cross section and the second trapezoidal cross section are both formed as isosceles trapezoids. Of course, the present invention is not limited thereto, and the first trapezoidal cross section and the second trapezoidal cross section may also be trapezoidal cross sections of other shapes such as right-angled trapezoids.

[0072] It can be understood that the sealing portion 42 has a first trapezoidal cross-section, the liquid outlet 117 has a second trapezoidal cross-section, and the first trapezoidal cross-section and the second trapezoidal cross-section are interference fit. When the sealing portion 42 moves toward the liquid outlet 117, it is convenient for the sealing portion 42 to fit with the liquid outlet 117, and it is also beneficial to ensure that the sealing portion 42 can reliably seal the liquid outlet 117.

[0073] In some optional embodiments of the present invention, referring to Figure 6 As shown, the sealing part 42 is integrally formed with the main body 41. It is understandable that the integrally formed structure can not only ensure the structural and performance stability of the sealing part 42 and the main body 41, but also facilitate molding and simplify manufacturing, and eliminate unnecessary assembly parts and connection processes, greatly improving the assembly efficiency of the sealing part 42 and the main body 41, and ensuring the reliability of the connection between the sealing part 42 and the main body 41. Moreover, the integrally formed structure has higher overall strength and stability, is more convenient to assemble, and has a longer service life. Further, in some examples, the sealing part 42, the main body 41 and the entire valve 4 are integrally formed.

[0074] In some embodiments of the present invention, reference Figure 6 As shown, the movement of the driving member 21 includes circumferential rotation, linear movement, or a combination of the two. In other words, the movement of the driving member 21 is circumferential rotation, or the movement of the driving member 21 is linear movement, or the movement of the driving member 21 is a combination of circumferential rotation and linear movement. Therefore, the movement form of the driving member 21 can be reasonably designed according to actual needs, which is conducive to meeting the diverse needs of different users.

[0075] In some optional embodiments of the present invention, the driving member 21 is in the first position (refer to Figure 6 ) and the second position (ref. Figure 7 ), when the driving member 21 is in the first position, the valve 4 closes the liquid outlet 117, and when the driving member 21 moves from the first position to the second position, the driving member 21 drives the valve 4 to move to open the liquid outlet 117. It can be understood that the movement stroke of the driving member 21 from the first position to the second position is related to the rotation angle of the pump body 12, and the rotation angle of the pump body 12 can be controlled by controlling the movement stroke of the driving member 21 from the first position to the second position, so as to realize the control of the single delivery amount of the delivery device 10, and the structure is simple and the operation is convenient.

[0076] In some examples, the driving member 21 is movable between a first position and a second position, and when the driving member 21 is in the first position, the valve 4 closes the liquid outlet 117, and when the driving member 21 is in a position between the first position and the second position, the valve 4 opens the liquid outlet 117, and when the driving member 21 is in any position between the certain position and the second position, the valve 4 opens the liquid outlet 117; or, the driving member 21 is movable between the first position and the second position, and when the driving member 21 is in the first position, the valve 4 closes the liquid outlet 117, and when the driving member 21 reaches the second position, the driving member 21 opens the liquid outlet 117.

[0077] For example, refer to Figure 6 and Figure 7 As shown, the driving member 21 is rotatably disposed on the housing driving member 21, and in the first position (refer to Figure 6 ) and the second position (ref. Figure 7 ), when the driving member 21 is in the first position, the valve 4 closes the liquid outlet 117, and when the driving member 21 is in the second position, the valve 4 opens the liquid outlet 117; in the process of rotating from the first position to the second position, the driving member 21 drives the pump body 12 to rotate to drive the liquid to flow from the liquid inlet 116 to the liquid outlet 117, and the driving member 21 drives the valve 4 to move to open the liquid outlet 117.

[0078] In some optional embodiments of the present invention, referring to Figure 6-Figure 7 As shown, the rotation axis of the driving member 21 extends substantially in the horizontal direction, and the first position is located above the second position. Figure 6-Figure 7As shown, the rotation axis of the driving member 21 is L, and the rotation axis L extends in the left-right direction. It can be understood that the trajectory of the driving member 21 rotating around the rotation axis L is an arc, and by making the first position above the second position, the user can press the driving member 21 to make the driving member 21 rotate from the first position to the second position, which is convenient for the user to apply force to drive the dispensing device 10 to dispense lotion, which is conducive to improving the user's use experience. Of course, the present invention is not limited to this, and the first position can also be located below the second position.

[0079] In some optional embodiments of the present invention, referring to Figure 6 and Figure 7 As shown, the angle between the first position and the second position is not greater than 120°. In other words, the angle between the line connecting the first position and the rotation center of the driving member 21 and the line connecting the second position and the rotation center of the driving member 21 is not greater than 120°. In other words, the rotation angle of the driving member 21 from the first position to the second position or from the second position to the first position is not greater than 120°. In this way, the angle between the first position and the second position will not be too large. On the one hand, it is beneficial to avoid excessive rotation stroke of the driving member 21. On the other hand, it is beneficial to avoid interference between the driving member 21 and other components, which is beneficial to ensure the reliability of the driving member 21. For example, Figure 7 As shown, the first position is above the second position, and the user presses down the free end of the driving member 21 to make the driving member 21 rotate counterclockwise from the first position to the second position around the rotation axis L. During this process, the rotation trajectory of the driving member 21 is an arc.

[0080] Among them, the rotation angle of the driving member 21 from the first position to the second position can be 10°, 20°, 30°, 40°, 50°, 60°, 70°, 80°, 90°, 100°, 110° or 120°, etc. The rotation angle of the driving member 21 from the first position to the second position can be adjusted and designed according to actual needs, and the present invention does not impose any specific restrictions on this.

[0081] In some optional embodiments of the present invention, referring to Figure 6 and Figure 7 As shown, the valve 4 is connected to the driving member 21. When the driving member 21 moves from the second position to the first position, the driving member 21 can drive the valve 4 to move to close the liquid outlet 117. It can be understood that by connecting the valve 4 to the driving member 21, it is convenient for the driving member 21 to drive the valve 4 to move to open or close the liquid outlet 117. For example, referring to Figure 1As shown, the valve 4 is fixedly connected to the driving member 21. When the driving member 21 rotates from the second position to the first position, the driving member 21 drives the valve 4 to rotate to close the liquid outlet 117. When the driving member 21 rotates from the first position to the second position, the driving member 21 drives the valve 4 to rotate to open the liquid outlet 117.

[0082] Optionally, in some examples, reference Figure 1 and Figure 6 As shown, the pump housing 11 includes a housing body 1111 and a discharge portion 1112. A pump chamber 113 is defined in the housing body 1111. The pump body 12 is located in the pump chamber 113. The discharge portion 1112 protrudes from the housing body 1111. The discharge portion 1112 has a flow channel 1113 connected to the pump chamber 113. The liquid outlet 117 is provided on one side wall of the discharge portion 1112 and is connected to the flow channel 1113. When the driving member 21 is located in the first position, the valve 4 cooperates with one side wall of the discharge portion 1112 (refer to Figure 6 Thus, when the driving member 21 is located at the first position, the valve 4 cooperates with the side wall of the discharge portion 1112 to ensure that the valve 4 can reliably close the liquid outlet 117, which is beneficial to prevent the delivery device 10 from leaking.

[0083] In some embodiments of the present invention, reference Figure 6 and Figure 7 As shown, the driving assembly 2 further includes a first elastic reset member 22, and the first elastic reset member 22 is used to drive the driving member 21 to reset to the first position. It can be understood that when the user drives the driving member 21 to move from the first position to the second position, the first elastic reset member 22 applies an elastic deformation force to the driving member 21 to turn to the first position. When the user releases the hand, the driving member 21 is reset to the first position under the drive of the first elastic reset member 22. Therefore, when the driving member 21 is operated to rotate from the first position to the second position, it is not necessary to manually reset the driving member 21 to the first position, which further facilitates the user's operation.

[0084] In some embodiments of the present invention, reference Figure 6 and Figure 7 As shown, one end of the first elastic reset member 22 is connected to the driving member 21 and the other end is connected to the pump housing 11. Figure 6 and Figure 7 As shown, the first elastic reset member 22 is a spring, the pump housing 11 and the storage box 20 are integrally formed, one end of the first elastic reset member 22 is connected to the upper part of the driving member 21 and the other end is connected to the outer wall of the storage box 20. It can be understood that, referring to Figure 6 and Figure 7As shown, when the driving member 21 is subjected to the driving force F, the first elastic reset member 22 is tensilely deformed. When the driving force F is withdrawn, the first elastic reset member 22 recovers its deformation to drive the driving member 21 to reset. The structure is simple and the operation is convenient.

[0085] In some optional embodiments of the present invention, the valve 4 is movably disposed at the liquid outlet 117, and the valve 4 is not connected to the driving member 21. When the driving member 21 moves from the first position to the second position, the driving member 21 pushes the valve 4 to move to open the liquid outlet 117. Thus, the structure is simple and the operation is convenient. Fig. 9 As shown, the valve 4 is movably disposed at the liquid outlet 117, and when the driving member 21 moves from the first position to the second position, the driving member 21 pushes the valve 4 to move to open the liquid outlet 117. For example, in one example, the valve 4 is rotatably disposed at the liquid outlet 117, and when the driving member 21 rotates from the first position to the second position, the driving member 21 pushes the valve 4 to rotate to open the liquid outlet 117.

[0086] For example, refer to Fig. 9 As shown, the valve 4 is movably arranged in the pump housing 11 along the front-rear direction. The pump housing 11 includes a housing body 1111, a liquid discharge portion 1112 and a stopper 118. The housing body 1111 defines a pump chamber 113 (see Figure 5 ), the discharge portion 1112 has a flow channel 1113 connected to the pump chamber 113, one side of the discharge portion 1112 is open to define a liquid outlet 117, the stopper 118 is spaced apart from the discharge portion 1112, one end of the push portion 214 is connected to the connecting portion 212 of the driving member 21, and the other end of the push portion 214 is formed with a first step 213, the valve 4 includes a main body portion 41 and a sealing portion 42 connected to each other, the upper end of the main body portion 41 is formed with a second step 43, the first step 213 is connected to the connecting portion 212 of the driving member 21, and the second step 43 is formed on the upper end of the main body portion 41. The second step 43 is engaged and matched to push the valve 4 to move, the sealing portion 42 is convexly arranged on one side of the main body 41 adjacent to the liquid outlet 117, the second elastic reset member 5 is connected between the main body 41 and the stopper 118 to always push the valve 4 to move in the direction of closing the liquid outlet 117, and the pump housing 11 is further provided with a guide structure 6, which extends in the axial direction of the second elastic reset member 5, and the guide structure 6 cooperates with the valve 4 to make the valve 4 move along the axial direction of the second elastic reset member 5. Optionally, refer to Fig. 9 As shown, the guide structures 6 can be multiple and arranged in parallel and spaced apart, which is beneficial to further ensure the reliable movement of the valve 4.

[0087] In some embodiments of the present invention, reference Figure 5As shown, the pump body 12 is rotatably disposed in the pump housing 11 , so that a liquid suction area 114 and a liquid discharge area 115 are formed in the pump housing 11 , the liquid inlet 116 corresponds to the liquid suction area 114 , and the liquid outlet 117 corresponds to the liquid discharge area 115 . For example, when the dispensing device 10 is in the initial state (there is no lotion in the discharge area 115), when the user drives the driving member 21 to rotate from the first position to the second position, the one-way transmission mechanism 3 drives the pump body 12 to move, which can generate negative pressure in the suction area 114 and positive pressure in the discharge area 115. The lotion at the liquid inlet 116 flows to the discharge area 115 under the action of the pressure difference. During this process, the suction at the liquid inlet 116 and the discharge at the liquid outlet 117 of the dispensing pump 1 are not synchronized in time until the lotion can be discharged from the liquid outlet 117. After that, when the dispensing device 10 is working normally, when the driving member 21 is rotated to dispense the lotion, the suction at the liquid inlet 116 and the discharge at the liquid outlet 117 of the dispensing pump 1 are synchronized in time.

[0088] It should be noted that the inventors found in actual research that the principle of the manual dispensing device in the related art is to use a reciprocating motion device similar to a plunger pump to change the volume ratio of the extraction and discharge device cavities to achieve liquid suction and discharge, and the liquid suction and discharge actions are performed alternately. In other words, the liquid suction and discharge of the manual dispensing device in the related art are located in the same area and are not synchronized in time. The discharge force is provided by manual pressure, and the power required for pumping is provided by spring reset, which is similar to the pressing dispensing device for shampoo or hand sanitizer in daily life. However, due to the large capacity of washing equipment such as washing machines and dishwashers, the amount of detergent required for each washing is much greater than the single use of hand sanitizer or shampoo in daily life. This requires making the pump cavity larger, or allowing the user to press more times, which will lead to a worse user experience.

[0089] According to the dispensing device 10 of the embodiment of the present invention, the movement stroke of the driving member 21 is related to the rotation angle of the pump body 12, and the movement stroke of the driving member 21 can be controlled to achieve quantitative control of the amount of detergent dispensed. Moreover, since the suction area 114 and the discharge area 115 of the dispensing pump 1 are located in different areas, when the dispensing device 10 is working normally, the suction at the liquid inlet 116 and the discharge at the liquid outlet 117 of the dispensing pump 1 are synchronized in time, so that the dispensing amount of the dispensing pump 1 is not limited by the volume of the dispensing pump 1, which is beneficial to increase the amount of detergent dispensed by the dispensing device 10 at a single time. Furthermore, on the basis of a certain volume of the dispensing device 10, the single dispensing amount of the dispensing device 10 can be increased and the dispensing accuracy of the single dispensing can be guaranteed, which is beneficial to reducing the number of dispensing times and ensuring the accuracy requirements, and can adapt to the requirements of large-capacity washing equipment 1000 such as washing machines and dishwashers for detergent dispensing, which is beneficial to improving the user experience.

[0090] In some optional embodiments of the present invention, referring to Figure 3 and Fig.10As shown, the pump body 12 includes two rotatable and externally meshed sub-pump bodies 121, and the one-way transmission mechanism 3 is connected between one of the sub-pump bodies 121 and the drive assembly 2. The sub-pump body 121 is a gear (refer to Figure 3 ) or screw (refer to Fig.10 ). Thus, the structure is simple, which is conducive to further improving the reliability of the pump body 12 and ensuring the accuracy of single delivery. Of course, the present invention is not limited to this. The pump body 12 can also be replaced by two rotatable and internally meshing gear pump bodies. For example, the pump body 12 can include an internal gear and an external gear. The external gear is located inside the internal gear and is eccentrically arranged relative to the internal gear. The driving member 21 of the driving assembly 2 is connected to the external gear. The rotation of the driving member 21 drives the external gear to rotate, and the external gear drives the internal gear to rotate, thereby driving the lotion in the pump housing 11 to flow, so as to generate negative pressure at the liquid inlet 116 and positive pressure at the liquid outlet 117. The lotion in the liquid suction area 114 flows to the liquid discharge area 115 under the action of the pressure difference and is discharged in sequence through the flow channel 1113 and the liquid outlet 117 to achieve the delivery of the lotion.

[0091] Of course, the present invention is not limited to this, Fig.11 As shown, the pump body 12 can also be an impeller pump 14, and a mounting cavity 13 with a circular cross-section is defined in the pump casing 11. The impeller pump 14 includes: a wheel disc 141 and a plurality of blades 142. The one-way transmission mechanism 3 is arranged between the driving component 2 and the wheel disc 141. The wheel disc 141 is rotatably arranged in the mounting cavity 13. The wheel disc 141 is eccentrically arranged relative to the mounting cavity 13. A suction and discharge cavity 131 is defined between the outer peripheral wall of the wheel disc 141 and the inner peripheral wall of the mounting cavity 13. The suction and discharge cavity 131 includes a liquid suction area 114 and a liquid discharge area 115. A plurality of blades 142 are spaced apart in the circumferential direction of the wheel disc 141, and one end of each blade 142 is connected to the wheel disc 141 and the other end is elastically stopped against the inner peripheral wall of the mounting cavity 13.

[0092] For example, Fig.11 As shown, one end of each blade 142 is connected to the wheel disc 141 through a spring member 143, so that the other end of each blade 142 elastically stops against the inner circumferential wall of the installation cavity 13. When the driving assembly 2 drives the impeller pump 14 to rotate clockwise, the blades 142 drive the rotation of the liquid in the installation cavity 13. Due to the eccentric setting of the wheel disc 141, negative pressure is generated at the liquid inlet 116, which has the effect of sucking liquid, and positive pressure is generated at the liquid outlet 117, so that the liquid is squeezed out at the liquid outlet 117, which has the effect of discharging liquid.

[0093] It can be understood that the amount of lotion dosed can be controlled by controlling the rotation angle of the driving member 21, and since the suction and discharge of the dosing pump 1 are synchronized in time, the amount of the dosing pump 1 is not limited by the volume of the dosing pump 1, the single dosing amount of the dosing device 10 can be increased and the dosing accuracy of the single dosing can be guaranteed. At the same time, since one end of each blade 142 is connected to the wheel disc 141 and the other end is elastically stopped against the inner wall of the installation cavity 13, reliable liquid intake and discharge of the dosing pump 1 can be guaranteed, and when the impeller pump 14 stops working, the other end of each blade 142 is elastically stopped against the inner wall of the installation cavity 13 to achieve closure, which is beneficial to avoid leakage of the dosing device 10.

[0094] In some embodiments of the present invention, reference Fig.11 As shown, the delivery device 10 further includes a cylindrical mounting seat 15, which is disposed in the pump housing 11 and fixed relative to the pump housing 11, and a mounting cavity 13 is formed in the mounting seat 15, and the mounting cavity 13 is eccentrically disposed relative to the mounting seat 15. It can be understood that by making the mounting seat 15 and the pump housing 11 separate, it is helpful to reduce the difficulty of processing the mounting seat 15 and the pump housing 11 respectively, and reduce the mold opening cost.

[0095] Of course, the present invention is not limited to this, and the mounting seat 15 and the pump housing 11 can also be an integral part. It is understandable that the integrally formed structure can not only ensure the structural and performance stability of the mounting seat 15 and the pump housing 11, but also facilitate molding and simple manufacturing, and save unnecessary assembly parts and connection processes, greatly improve the assembly efficiency of the mounting seat 15 and the pump housing 11, and ensure the reliability of the connection between the mounting seat 15 and the pump housing 11. Moreover, the integrally formed structure has higher overall strength and stability, is more convenient to assemble, and has a longer service life.

[0096] In some embodiments of the present invention, reference Figure 6 As shown, the driving assembly 2 includes a transmission mechanism 23, and the transmission mechanism 23 is connected between the driving member 21 and the pump body 12. Therefore, by reasonably setting the transmission ratio between the driving member 21, the transmission mechanism 23 and the pump body 12, the single delivery amount of the delivery device 10 can be increased and the delivery times can be reduced.

[0097] In some embodiments of the present invention, reference Figure 6 As shown, the transmission mechanism 23 includes a first transmission member 231 and a second transmission member 232 that mesh with each other, the first transmission member 231 is connected to the driving member 21, and the second transmission member 232 is connected to the pump body 12. It can be understood that by making the transmission mechanism 23 include the first transmission member 231 and the second transmission member 232 that mesh with each other, it is helpful to improve the reliability of the transmission mechanism 23, and the structure is simple and easy to operate. For example, referring to Figure 6 and Figure 7As shown, the second transmission member 232 can be connected to the sub-pump body 121 located on the rear side. When the driving member 21 rotates counterclockwise from the first position to the second position, the first transmission member 231 drives the second transmission member 232 to rotate counterclockwise, and the second transmission member 232 drives the sub-pump body 121 to rotate counterclockwise. The sub-pump body 121 drives the sub-pump body 121 located on the front side to rotate, thereby driving the liquid to flow from the suction area 114 to the discharge area 115, and to flow to the liquid outlet 117 through the flow channel 1113. At the same time, the driving member 21 drives the valve 4 to open the liquid outlet 117 to release the lotion.

[0098] In some embodiments of the present invention, reference Figure 6 As shown, the pump body 12 is driven to move by the rotation of the driving member 21, the first transmission member 231 is an arc-shaped rack and extends circumferentially along the rotation axis of the driving member 21, and the second transmission member 232 is a gear. For example, the second transmission member 232 is a gear and is located outside the delivery pump 1, and part of the pump body 12 passes through the pump housing 11 and is connected to the second transmission member 232. It can be understood that since the rotation trajectory of the driving member 21 is an arc, by making the first transmission member 231 an arc-shaped rack, it is beneficial to improve the reliability of the cooperation between the first transmission member 231 and the second transmission member 232 and extend the service life.

[0099] In some embodiments of the present invention, reference Figure 6 As shown, the driving member 21 includes a pressing portion 211 and a connecting portion 212, the connecting portion 212 is rotatably connected to the pump housing 11, the pressing portion 211 is connected to the end of the connecting portion 212 away from the pump housing 11, the first transmission member 231 is connected to the pressing portion 211, and the second transmission member 232 is located in the accommodating cavity 24 defined by the first transmission member 231 and the connecting portion 212. It can be understood that by making the second transmission member 232 located in the accommodating cavity 24 defined by the first transmission member 231 and the connecting portion 212, it is helpful to reduce the entry of foreign debris into the matching position of the first transmission member 231 and the second transmission member 232, thereby ensuring the reliability of the matching between the second transmission member 232 and the first transmission member 231. For example, referring to Figure 6 As shown, the accommodating cavity 24 forms an arc-shaped cavity, and the center of the arc-shaped cavity coincides with the rotation center of the driving member 21 .

[0100] Optionally, in some examples of the present application, reference is made to Figure 6 As shown, the pressing portion 211 and the connecting portion 212 are an integral part. It can be understood that the integrally formed structure can not only ensure the structural and performance stability of the pressing portion 211 and the connecting portion 212, but also facilitate molding and simple manufacturing, and eliminate unnecessary assembly parts and connection procedures, thereby greatly improving the assembly efficiency of the pressing portion 211 and the connecting portion 212, and ensuring the reliability of the connection between the pressing portion 211 and the connecting portion 212. Furthermore, the integrally formed structure has higher overall strength and stability, is more convenient to assemble, and has a longer service life.

[0101] In some embodiments of the present invention, as shown in reference 5, the dispensing device 10 also includes a one-way transmission mechanism 3, and the driving member 21 can move between a first position and a second position. The one-way transmission mechanism 3 is located between the driving assembly 2 and the pump body 12, wherein, during the movement of the driving member 21 from the first position to the second position, the driving member 21 drives the valve 4 to move to open the liquid outlet 117, and at the same time drives the one-way transmission mechanism 3 to move, the one-way transmission mechanism 3 drives the pump body 12 to move, suck the lotion from the liquid inlet 116 and discharge it from the liquid outlet 117, during the movement of the driving member 21 from the second position to the first position, the driving assembly 2 drives the one-way transmission mechanism 3 to move, and the one-way transmission mechanism 3 does not drive the pump body 12 to move, in other words, during the movement of the driving member 21 from the second position to the first position, the one-way transmission mechanism 3 and the pump body 12 are disengaged from the transmission cooperation, and when the driving member 21 returns to the first position, the valve 4 closes the liquid outlet 117.

[0102] For example, refer to Figure 6 and Figure 7 As shown, the user can manually drive the driving member 21 to move from the first position to the second position, and the driving member 21 drives the valve 4 to move to open the liquid outlet 117. At the same time, the one-way transmission mechanism 3 drives the pump body 12 to move, so that the lotion is sucked from the liquid inlet 116 and discharged from the liquid outlet 117, so as to realize semi-automatic delivery of the delivery device 10, that is, the lotion is delivered manually. When the user manually drives the driving member 21 to move from the second position to the first position, the driving assembly 2 drives the one-way transmission mechanism 3 to move, and the one-way transmission mechanism 3 and the pump body 12 are disengaged from the transmission cooperation, and the one-way transmission mechanism 3 does not drive the pump body 12 to move. When the driving member 21 returns to the first position, the valve 4 closes the liquid outlet 117.

[0103] It can be understood that by setting up the one-way transmission mechanism 3, in the process of the driving member 21 moving from the second position to the first position, the driving member 21 drives the one-way transmission mechanism 3 to move, and the one-way transmission mechanism 3 does not drive the pump body 12 to move, which is beneficial to avoid the reverse suction of the lotion by the delivery pump 1 through the liquid outlet 117, and is beneficial to ensure the accuracy of lotion delivery. At the same time, in the process of the driving member 21 moving from the second position to the first position, since the one-way transmission mechanism 3 does not drive the pump body 12 to move, it is beneficial to reduce the resistance of the driving member 21 moving from the second position to the first position, which is beneficial to improve the user's operating experience, and when the driving member 21 returns to the first position, the valve 4 closes the liquid outlet 117, which can effectively prevent the residual liquid from drying up, solidifying, oxidizing and other problems, and can also reduce the sealing requirements of the pump body 12 in the delivery device 10, and is beneficial to simplify the structure of the delivery device 10, reduce the manufacturing difficulty, save costs, and at the same time do not increase the user's operating difficulty.

[0104] In some embodiments of the present invention, referring to Figure 6 As shown, the one-way transmission mechanism 3 is a one-way rotation mechanism, wherein when the driving member 21 is moved from the first position (refer to Figure 6 ) moves to the second position (refer to Figure 7 ), the driving member 21 drives the valve 4 to move to open the liquid outlet 117, and at the same time, the one-way transmission mechanism 3 is driven by the driving component 2 along the first direction (refer to Figure 5 The one-way transmission mechanism 3 cooperates with the pump body 12 to drive the pump body 12 to move; when the driving assembly 2 moves from the second position to the first position, the one-way transmission mechanism 3 rotates in a second direction opposite to the first direction, and the one-way transmission mechanism 3 and the pump body 12 are disengaged from the transmission cooperation, and the pump body 12 does not rotate. It can be understood that by cooperating or disengaging the one-way transmission mechanism 3 with the pump body 12, it is possible to control whether the driving member 21 drives the pump body 12 to move, which has a simple structure and is easy to operate.

[0105] For example, refer to Figure 4 and Figure 5 As shown, when the dosing pump 1 is working normally, during the process of the driving member 21 rotating from the first position to the second position, the driving member 21 drives the valve 4 to move to open the liquid outlet 117, and at the same time, the one-way transmission mechanism 3 rotates counterclockwise under the drive of the driving component 2, and the one-way transmission mechanism 3 cooperates with one of the sub-pump bodies 121 to drive the sub-pump body 121 to rotate, and the sub-pump body 121 drives the other sub-pump body 121 to rotate, thereby generating negative pressure in the liquid suction area 114 and positive pressure in the liquid discharge area 115, and the lotion at the liquid inlet 116 flows to the liquid outlet 117 under the action of the pressure difference; during the process of the driving component 2 rotating from the second position to the first position, the one-way transmission mechanism 3 rotates clockwise, the one-way transmission mechanism 3 is disengaged from the transmission cooperation with the sub-pump body 121, and the sub-pump body 121 does not rotate, thereby preventing directional suction, and when the driving member 21 returns to the first position, the valve 4 closes the liquid outlet 117.

[0106] Of course, the present invention is not limited to this, and the pump body 12 can also be driven to rotate by moving the driving member 21. Specifically, in the process of the driving member 21 moving from the first position to the second position, the one-way transmission mechanism 3 rotates along the first direction driven by the driving component 2, and the one-way transmission mechanism 3 cooperates with one of the sub-pump bodies 121 to drive the sub-pump body 121 to rotate, and the sub-pump body 121 drives the other sub-pump body 121 to rotate, thereby generating negative pressure in the suction area 114 and positive pressure in the discharge area 115, and the lotion at the liquid inlet 116 flows to the liquid outlet 117 under the action of the pressure difference; in the process of the driving component 22 moving from the second position to the first position, the one-way transmission mechanism 3 rotates in a second direction opposite to the first direction, and the one-way transmission mechanism 3 is disengaged from the transmission cooperation with the sub-pump body 121, and the sub-pump body 121 does not rotate, thereby preventing reverse suction.

[0107] In some optional embodiments of the present invention, referring to Figure 4 As shown. A matching cavity 122 is formed in the pump body 12, and at least a part of the one-way transmission mechanism 3 is located in the matching cavity 122. In other words, part of the one-way transmission mechanism 3 may be located in the matching cavity 122, or the entire one-way transmission mechanism 3 may be located in the matching cavity 122. When the one-way transmission mechanism 3 rotates in the first direction, the one-way transmission mechanism 3 abuts against the inner wall of the matching cavity 122 to drive the pump body 12 to rotate; when the one-way transmission mechanism 3 rotates in the second direction, the one-way transmission mechanism 3 is out of transmission cooperation with the inner wall of the matching cavity 122. Among them, "the one-way transmission mechanism 3 is out of transmission cooperation with the inner wall of the matching cavity 122" can be understood as that the one-way transmission mechanism 3 does not transmit the force that drives the pump body 12 to rotate to the inner wall of the matching cavity 122, for example, the one-way transmission mechanism 3 is separated from the inner wall of the matching cavity 122, or, although the one-way transmission mechanism 3 is in contact with the matching cavity 122, the one-way transmission mechanism 33 cannot drive the pump body 12 to rotate through the inner wall of the matching cavity 122.

[0108] It can be understood that by locating at least a portion of the one-way transmission mechanism 3 in the mating cavity 122, the space occupied by the pump body 12 and the one-way transmission mechanism 3 as a whole can be reduced. At the same time, by abutting or separating the one-way transmission mechanism 3 from the inner wall of the mating cavity 122, it is helpful to ensure the reliability of the one-way transmission of the one-way transmission mechanism 3.

[0109] In some optional embodiments of the present invention, referring to Figure 5 As shown, a first matching tooth 123 is formed on the inner wall of the matching cavity 122, and the one-way transmission mechanism 3 includes a one-way transmission wheel 3a located in the matching cavity 122, and the one-way transmission wheel 3a includes a transmission shaft 31 and a second matching tooth 32 connected to the transmission shaft 31, and at least one of the first matching tooth 123 and the second matching tooth 32 has elasticity. In other words, one of the first matching tooth 123 and the second matching tooth 32 may have elasticity, or both of the first matching tooth 123 and the second matching tooth 32 may have elasticity. When the one-way transmission wheel 3a is moved along the first direction with reference to Figure 4 When the one-way transmission wheel 3a rotates counterclockwise, the second matching tooth 32 and the first matching tooth 123 abut against each other at least in the circumferential direction to drive the pump body 12 to rotate; when the one-way transmission wheel 3a rotates in the second direction, the first matching tooth 123 and the second matching tooth 32 are disengaged. It can be understood that by making at least one of the first matching tooth 123 and the second matching tooth 32 an elastic member, when the one-way transmission wheel 3a rotates in the second direction, it is helpful to ensure that the first matching tooth 123 and the second matching tooth 32 are in a disengaged state, thereby ensuring the reliability of the one-way transmission mechanism 3.

[0110] For example, as shown in Reference 5, a plurality of first mating teeth 123 are formed on the inner wall of the mating cavity 122 of the sub-pump body 121 located on the rear side, and the cross-section of each first mating tooth 123 is formed in a wedge shape. The plurality of first mating teeth 123 are evenly spaced and arranged on the inner circumferential wall of the mating cavity 122. The one-way transmission mechanism 3 includes a one-way transmission wheel 3a located in the mating cavity 122, and the one-way transmission wheel 3a includes a transmission shaft 31 and a second mating tooth 32 connected to the transmission shaft 31. The first mating tooth 123 is a rigid part, and the second mating tooth 32 is elastic. When the one-way transmission wheel 3a rotates counterclockwise, the second mating tooth 32 and the first mating tooth 123 abut in the circumferential direction to drive the pump body 12 to rotate; when the one-way transmission wheel 3a33 rotates clockwise, the first mating tooth 123 and the second mating tooth 32 are disengaged.

[0111] In some embodiments of the present invention, reference Figure 5 As shown, the second mating tooth 32 is elastic, and the second mating tooth 32 includes a connecting section 321 and a mating section 322. The connecting section 321 is connected to the transmission shaft 31 and extends radially outward, and the mating section 322 is connected to an end of the connecting section 321 away from the transmission shaft 31. The mating section 322 extends along the circumference of the transmission shaft 31 and is spaced from the transmission shaft 31. It can be understood that by making the second mating tooth 32 include the connecting section 321 and the mating section 322, when the one-way transmission mechanism 3 is moved along the first direction (refer to Figure 5 When the one-way transmission mechanism 3 rotates in the second direction, the first mating tooth 123 and the mating segment 322 abut against each other in the circumferential direction, which is beneficial to ensuring the reliability of the abutment between the first mating tooth 123 and the second mating tooth 32. When the one-way transmission mechanism 3 rotates along the second direction, the mating segment 322 can be deformed inwardly to make the first mating tooth 123 slip relative to the second mating tooth 32, which is beneficial to ensuring that the first mating tooth 123 and the second mating tooth 32 are out of transmission cooperation, thereby preventing the occurrence of reverse liquid suction.

[0112] In some examples, the second transmission member 232 and the one-way transmission wheel 3a are integrally formed. It is understandable that the integrally formed structure can not only ensure the structural and performance stability of the second transmission member 232 and the one-way transmission wheel 3a, but also facilitates molding and is simple to manufacture, and eliminates unnecessary assembly parts and connection procedures, greatly improving the assembly efficiency of the second transmission member 232 and the one-way transmission wheel 3a, ensuring the reliability of the connection between the second transmission member 232 and the one-way transmission wheel 3a, and further, the integrally formed structure has higher overall strength and stability, is more convenient to assemble, and has a longer service life.

[0113] In one example, referring to Figure 5As shown, a mating cavity 122 is formed in the sub-pump body 121 located on the rear side, the one-way transmission mechanism 3 is located in the mating cavity 122 and is a rotating transmission mechanism, a plurality of first mating teeth 123 are formed on the inner wall of the mating cavity 122, and the cross-section of each first mating tooth 123 is formed in a wedge shape, the one-way transmission mechanism 3 includes a one-way transmission wheel 3a located in the mating cavity 122, the one-way transmission wheel 3a includes a transmission shaft 31 and a second mating tooth 32 connected to the transmission shaft 31, the second mating tooth 32 is elastic and suitable for mating with the first mating tooth 123, the second mating tooth 32 includes a connecting section 321 and a mating section 322, the connecting section 321 is connected to the transmission shaft 31 and extends radially outward, the mating section 322 is connected to the end of the connecting section 321 away from the transmission shaft 31, and the mating section 322 extends circumferentially along the transmission shaft 31 and is spaced apart from the transmission shaft 31.

[0114] It is understandable that when the delivery device 10 is operating normally, when the driving member 21 is moved from the first position (refer to Figure 5 ) to the second position (refer to Figure 6 ), the driving member 21 drives the valve 4 to move to open the liquid outlet 117, and at the same time, the transmission shaft 31 rotates counterclockwise under the drive of the driving member 21, and the connecting section 321 of the second matching tooth 32 abuts and cooperates with the first matching tooth 123 of the sub-pump body 121 located at the rear side in the circumferential direction to drive the sub-pump body 121 to rotate, and the sub-pump body 121 drives the other sub-pump body 121 to rotate, thereby generating negative pressure in the liquid suction area 114 and positive pressure in the liquid discharge area 115, and the lotion at the liquid inlet 116 flows to the liquid outlet 117 under the action of the pressure difference; in the process of the driving member 21 rotating from the second position to the first position, the driving assembly 2 drives the one-way transmission wheel 3 a rotates in the clockwise direction, the first mating tooth 123 slips relative to the second mating tooth 32, the one-way transmission mechanism 3 and the sub-pump body 121 are disengaged from the transmission cooperation, and the sub-pump body 121 does not drive the other sub-pump body 121 to rotate, which is beneficial to avoid the reverse suction of lotion by the delivery pump 1 through the liquid outlet 117, and the accuracy of lotion delivery is high. At the same time, in the process of the driving member 21 rotating from the second position to the first position, the mating segment 322 is deformed inwardly, and the first mating tooth 123 slips relative to the mating segment 322 to disengage from the transmission cooperation, which can avoid the reverse suction of liquid by the delivery pump 1, and when the driving member 21 reaches the first position, the driving member 21 drives the valve 4 to close the liquid outlet 117.

[0115] In some embodiments of the present invention, reference Figure 3As shown, the first transmission member 231, the driving member 21 and the valve 4 are integrally formed. It can be understood that the integrally formed structure can not only ensure the structural and performance stability of the first transmission member 231, the driving member 21 and the valve 4, but also facilitates molding and is simple to manufacture, and eliminates redundant assembly parts and connection procedures, greatly improving the assembly efficiency of the first transmission member 231, the driving member 21 and the valve 4, ensuring the reliability of the connection between the first transmission member 231, the driving member 21 and the valve 4, and further, the integrally formed structure has higher overall strength and stability, is more convenient to assemble, and has a longer service life.

[0118] In some embodiments of the present invention, reference Figure 1 and Figure 2 As shown, the storage box 20 is arranged on the pump housing 11, for example, the storage box 20 is located above the pump housing 11 and connected to the pump housing 11. This is conducive to reducing the overall space occupied by the storage box 20 and the pump housing 11, and is conducive to miniaturization of the delivery assembly 100; or, in other embodiments, the storage box 20 is connected to the pump housing 11 through a connecting pipe, thereby, the connection is convenient, the storage box 20 and the pump housing 11 can be arranged separately, and the flexibility of installation of the delivery assembly 100 can be improved.

[0119] In some embodiments of the present invention, reference Figure 1 and Figure 2 As shown, the storage box 20 is disposed on the pump housing 11, and the storage box 20 is detachably connected to the pump housing 11. It is understandable that by detachably connecting the storage box 20 to the pump housing 11, it is easy to replace or repair the storage box 20 and the pump housing 11, which is conducive to reducing maintenance costs.

[0120] For example, in one example, referring to Figure 1 and Figure 2 As shown, the pump housing 11 includes a housing portion 111 and an end cap 112, the housing portion 111 and the storage box 20 are integrally formed, and the end cap 112 is detachably arranged at the open end of the integral part formed by the housing portion 111 and the storage box 20 through a threaded fastener. It can be understood that the integrally formed structure can not only ensure the structural and performance stability of the housing portion 111 and the storage box 20, but also facilitate molding and simple manufacturing, and eliminate unnecessary assembly parts and connection processes, greatly improving the assembly efficiency of the housing portion 111 and the storage box 20. At the same time, the threaded fastener has the advantages of simple structure and easy assembly. The threaded fastener can realize the tight connection between the end cap 112 and the integral part formed by the housing portion 111 and the storage box 20. In addition, while ensuring the connection strength of the integral part formed by the end cap 112, the housing portion 111 and the storage box 20, the cost can also be reduced. Optionally, the threaded fastener can be a screw, a bolt or a stud.

[0121] Alternatively, in other embodiments, the storage box 20 is integrally formed with the pump housing 11. It is understandable that the integrally formed structure can not only ensure the structural and performance stability of the storage box 20 and the pump housing 11, but also facilitates molding and is simple to manufacture, and eliminates redundant assembly parts and connection procedures, greatly improving the assembly efficiency of the storage box 20 and the pump housing 11, ensuring the reliability of the connection between the storage box 20 and the pump housing 11, and further, the integrally formed structure has higher overall strength and stability, is more convenient to assemble, and has a longer service life.

Of course, the present invention is not limited to this, and the delivery assembly 100 can also directly deliver the detergent into the washing tank 400.

[0124] According to the washing device 1000 of the embodiment of the present invention, by providing the above-mentioned dispensing component 100, the residual liquid can be effectively prevented from drying up, solidifying, oxidizing and other problems, and the sealing requirements of the pump body 12 in the dispensing device 10 can be reduced, which is beneficial to simplifying the structure of the dispensing device 10, reducing the manufacturing difficulty, saving costs, and thus helping to improve the overall performance of the washing device 1000.

[0128] Reference Figure 1 and Figure 2 As shown, the dispensing assembly 100 includes a dispensing device 10 and a storage box 20 for storing lotion, and the storage box 20 is connected to the dispensing device 10 to provide lotion to the dispensing device 10. Figure 3-Figure 5 As shown, the delivery device 10 includes a delivery pump 1, a drive assembly 2, a one-way transmission mechanism 3 and a valve 4. The delivery pump 1 includes a pump casing 11 and a pump body 12. The pump casing 11 includes a casing portion 111 and an end cover 112. The casing portion 111 and the storage box 20 are integrally formed.

[0129] Furthermore, the shell portion 111 includes a shell body 1111 and a drainage portion 1112 . A pump chamber 113 is defined in the shell body 1111 . The pump body 12 is located in the pump chamber 113 . The drainage portion 1112 protrudes from the shell body 1111 and has a flow channel 1113 connected to the pump chamber 113 .

[0130] Reference Figure 5As shown, the pump body 12 is located in the pump chamber 113 and includes two rotatable and externally meshed sub-pump bodies 121, the two sub-pump bodies 121 are arranged in the front-to-back direction, each sub-pump body 121 is a gear, and the two sub-pump bodies 121 form a suction area 114 and a discharge area 115 arranged in the up-down direction in the pump chamber 113, and a liquid inlet 116 corresponding to the suction area 114 and a liquid outlet 117 corresponding to the discharge area 115 are formed on the pump housing 11, the liquid inlet 116 is located above the meshing portion of the two sub-pump bodies 121 and is connected to the storage box 20, and the liquid outlet 117 is formed on the front side wall of the discharge portion 1112 and is connected to the discharge area 115 through the flow channel 1113.

[0132] Reference Figure 1-Figure 3 As shown, the driving assembly 2 is located on the left side of the dosing pump 1, and the driving assembly 2 includes a driving member 21, a transmission mechanism 23 and an elastic reset member. The driving member 21 includes a pressing portion 211 and a connecting portion 212. The connecting portion 212 is rotatably connected to the pump housing 11, and the pressing portion 211 is connected to the end of the connecting portion 212 away from the pump housing 11. The valve 4 and the driving member 21 are integrally formed. When the valve 4 closes the liquid outlet 117, the sealing portion 42 is fitted into the liquid outlet 117. The sealing portion 42 is arranged opposite to the liquid outlet 117. The sealing portion 42 has a first trapezoidal cross-section, and the liquid outlet 117 has a second trapezoidal cross-section. The first trapezoidal cross-section and the second trapezoidal cross-section are interference fit.

[0133] The driving member 21 is rotatable between a first position and a second position. Figure 6 ), part of the sealing portion 42 is located in the liquid outlet 117 so that the valve 4 closes the liquid outlet 117. During the process of the driving member 21 rotating from the first position to the second position, the driving member 21 drives the valve 4 to rotate to open the liquid outlet 117.

[0134] Reference Figure 6As shown, the transmission mechanism 23 includes a first transmission member 231 and a second transmission member 232 that are meshed with each other. The first transmission member 231 is an arc-shaped rack and extends circumferentially along the rotation axis of the driving member 21. The second transmission member 232 is a gear. The first transmission member 231 is connected to the pressing portion 211, and the second transmission member 232 is connected to one axial side of one of the sub-pump bodies 121 and is integrally formed with the one-way transmission wheel 3a. The second transmission member 232 is located in the accommodating cavity 24 defined by the first transmission member 231 and the connecting portion 212. The first elastic return member 22 is a spring. The first elastic return member 22 is located above the driving member 21 and connected between the pressing portion 211 and the pump housing 11.

[0135] Specifically, when the dispensing device 10 is working normally, in the process of the driving member 21 rotating from the first position to the second position, the first transmission member 231 drives the second transmission member 232 to rotate, the driving member 21 drives the valve 4 to rotate to open the liquid outlet 117, the first transmission member 231 drives the second transmission member 232 to rotate, and the second transmission member 232 drives the corresponding sub-pump body 121 to rotate through the one-way transmission mechanism 3, and the sub-pump body 121 is engaged with another sub-pump body 121 to drive the other sub-pump body 121 to rotate, so as to drive the liquid to flow from the liquid inlet 116 to the liquid outlet 117 to realize the dispensing of the lotion.

[0136] It is understandable that, referring to Figure 5 As shown, the liquid suction area 114 and the liquid discharge area 115 of the delivery pump 1 used in the embodiment of the present invention are located in different areas. When the delivery device 10 works normally, the liquid suction at the liquid inlet 116 and the liquid discharge at the liquid outlet 117 of the delivery pump 1 are completed synchronously in time, so no large restoring force is required, and only a small force is required to complete the delivery, which can greatly improve the comfort of user operation. At the same time, the transmission ratio of the first transmission member 231 and the second transmission member 232 is fixed and the rotation angle of the driving member 21 is fixed, so that the number of rotations of the corresponding sub-pump body 121 can be fixed, and the single delivery amount of the delivery device 10 can be fixed. The user can obtain the accurate total delivery amount by controlling the number of delivery times. On the basis of a certain volume of the delivery device 10, the single delivery amount of the delivery device 10 in the embodiment of the present invention is large, which is conducive to reducing the number of user delivery operations and further improving the user experience.

[0137] When the user's driving force is withdrawn, under the action of the first elastic reset member 22, the driving member 21 automatically returns to the first position clockwise from the second position. In this process, the second transmission mechanism 23 drives the first transmission mechanism 23 to rotate clockwise, and the first transmission mechanism 23 drives the one-way transmission wheel 3a to rotate clockwise so that the matching section 322 is deformed inwardly, and the matching section 322 and the first matching tooth 123 slip so that the matching section 322 does not transmit power to the corresponding sub-pump body 121, so that the one-way transmission mechanism 3 has a one-way transmission effect, which can avoid the phenomenon of reverse liquid suction by the delivery pump 1. At the same time, when the first elastic reset member 22 reaches the first position, part of the sealing portion 42 is located in the liquid outlet 117 so that the valve 4 closes the liquid outlet 117. When the delivery pump 1 does not deliver lotion, the liquid outlet 117 can be ensured to be in a closed state, which can effectively prevent the residual liquid from drying up, solidifying, oxidizing and other problems, and can also reduce the sealing requirements of the pump body 12 in the delivery device 10, and is conducive to simplifying the structure of the delivery device 10, reducing the manufacturing difficulty and saving costs.
