[0054] 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 only used to explain the present invention, and cannot be understood as limiting the present invention.

[0055] The dispensing device 100 according to an embodiment of the present invention is described below with reference to the accompanying drawings. The dispensing device 100 can be used in a laundry processing device such as a washing machine, and is used to dispense detergent 400, which can be liquid detergent 400 such as laundry liquid and softener.

[0056] Reference Figure 1-Figure 8 The dispensing device 100 according to the first embodiment of the present invention is used in a clothing processing device. The clothing processing device includes an inner barrel having a washing cavity. The dispensing device 100 is used to dispense detergent 400 into the washing cavity.

[0057] Reference Figure 1-Figure 8 The dispensing device 100 includes: a dispensing pump 10, which can suck in the lotion 400 and then discharge it, so as to achieve automatic or semi-automatic dispensing of the lotion 400. The dispensing pump 10 includes a housing 1 and a pump body 2, the pump body 2 is arranged in the housing 1, and the pump body 2 may include a first sub-pump body 2A and a second sub-pump body 2B that are arranged in cooperation with each other, and the first sub-pump body 2A and the second sub-pump body 2B are both movable, and the lotion 400 can be pumped by the cooperation and movement between the first sub-pump body 2A and the second sub-pump body 2B.

[0058] When there is a transmission relationship between the first sub-pump body 2A and the second sub-pump body 2B, the cooperation between the first sub-pump body 2A and the second sub-pump body 2B refers to the transmission cooperation between the first sub-pump body 2A and the second sub-pump body 2B, and the first sub-pump body 2A, the second sub-pump body 2B and the inner wall of the shell 1 jointly define a liquid suction area and a liquid discharge area. During the movement and cooperation of the first sub-pump body 2A and the second sub-pump body 2B, the lotion 400 can be sucked into the liquid suction area, and the movement and cooperation of the first sub-pump body 2A and the second sub-pump body 2B drive the lotion 400 to flow from the liquid suction area to the liquid discharge area, and finally be discharged from the liquid discharge area.

[0059] When there is no transmission relationship between the first sub-pump body 2A and the second sub-pump body 2B, the cooperation between the first sub-pump body 2A and the second sub-pump body 2B refers to that the first sub-pump body 2A, the second sub-pump body 2B and the inner wall of the shell 1 jointly define a suction area and a discharge area. During the movement and cooperation of the first sub-pump body 2A and the second sub-pump body 2B, the movement of the first sub-pump body 2A and the second sub-pump body 2B does not interfere with each other, ensuring the smooth movement of the first sub-pump body 2A and the second sub-pump body 2B, and the lotion 400 can be sucked into the suction area, and the movement of the first sub-pump body 2A and the second sub-pump body 2B and the cooperation drive the lotion 400 from the suction area to the discharge area, and finally be discharged from the discharge area.

[0060] Among them, the first sub-pump body 2A and the second sub-pump body 2B are arranged along a first direction (for example, referring to the up and down direction in the attached figure), and the first sub-pump body 2A and the second sub-pump body 2B are arranged side by side in the first direction, and the first direction is parallel to the axial direction of the inner barrel. The delivery port 601 of the clothing processing device is arranged on one side in the axial direction of the inner barrel, and the clothes are put into the washing chamber of the inner barrel through the delivery port 601 for washing. By arranging the first sub-pump body 2A and the second sub-pump body 2B along the axial direction of the inner barrel, the axial space of the inner barrel can be fully utilized, so that the delivery pump 10 can fully utilize the axial space of the inner barrel, and reduce the space occupied by the delivery pump 10 in the workbench 600, thereby reducing or avoiding the use of the delivery port 601 in the workbench 600. In addition, it is conducive to realizing the tilting and pressing of the delivery device 100, which is convenient for users to operate the delivery device 100.

[0061] For example, refer to 1 and Figure 7 The clothing processing device may be a pulsator washing machine, the axis of the inner barrel extends in the up-down direction, the workbench 600 is arranged above the inner barrel, a delivery port 601 is formed in the workbench 600 and is opposite to and communicates with the washing chamber in the up-down direction, the delivery device 100 is installed in the workbench 600 and adjacent to the delivery port 601, and the delivery device 100 is installed in the part of the workbench 600 located at the rear side of the delivery port 601. Among them, the first sub-pump body 2A and the second sub-pump body 2B of the delivery pump 10 are arranged in the up-down direction, which can make full use of the space in the up-down direction, reduce the occupation of the space in the horizontal direction of the workbench 600, effectively save the space behind the workbench 600, make the space more effectively utilized, and facilitate the overall layout planning inside the workbench 600, and can reduce the space occupied by the delivery device 100 in the delivery port 601, thereby reducing or avoiding the impact on the use of the delivery port 601 in the workbench 600. Moreover, it is helpful to realize tilting and pressing the delivery device 100 backward and downward, so that the user can apply force to the delivery device 100 to drive the delivery device 100 to work, and the user can operate the delivery device 100 conveniently.

[0062] According to some embodiments of the present invention, referring to Figure 1-Figure 8 The housing 1 of the dosing pump 10 has a liquid inlet 111 and a liquid outlet 112. The above-mentioned liquid suction area is formed near the liquid inlet 111 and the liquid suction area is connected to the liquid inlet 111. The above-mentioned liquid discharge area is formed near the liquid outlet 112 and the liquid discharge area is connected to the liquid outlet 112. The dosing device 100 includes a transmission assembly, which is connected to the pump body 2. The transmission assembly is suitable for being driven to drive the pump body 2 to move. For example, the transmission assembly can be driven by a user applying a force. When the transmission assembly of the dosing device 100 is driven, the transmission assembly transmits force to the pump body 2, thereby driving the pump body 2 to move. Specifically, it can drive the first sub-pump body 2A and the second sub-pump body 2B to move, so that negative pressure can be formed in the liquid suction area and positive pressure can be formed in the liquid discharge area. The lotion 400 can be sucked into the liquid suction area from the liquid inlet 111, and the lotion 400 entering the liquid suction area is driven by the pump body 2 to flow to the liquid discharge area, and finally discharged from the liquid outlet 112. By means of the transmission assembly, the movement of the pump body 2 can be easily achieved, thereby enabling the automatic or semi-automatic delivery of the lotion 400 to be easily achieved.

[0063] Optionally, the transmission assembly may also move under the drive of other power sources.

[0064] According to some embodiments of the present invention, referring to Figure 8 , the liquid inlet 111 can be arranged higher than the liquid outlet 112. It can be understood that the liquid inlet 111 is arranged higher than the liquid outlet 112, so that the lotion 400 can be more easily poured out through the liquid outlet 112 under the action of gravity. Of course, the present invention is not limited to this. In another example of the present invention, the liquid inlet 111 can be at a height equivalent to that of the liquid outlet 112.

[0065] According to some optional embodiments of the present invention, referring to Figure 1-Figure 6 The transmission assembly includes an active member 36 connected to the first sub-pump body 2A and a driven member 37 connected to the second sub-pump body 2B. The active member 36 can be connected to one axial side of the first sub-pump body 2A and fixed relative to the first sub-pump body 2A. The active member 36 and the first sub-pump body 2A can be coaxially arranged. The driven member 37 can be connected to one axial side of the second sub-pump body 2B and fixed relative to the second sub-pump body 2B. The driven member 37 and the second sub-pump body 2B can be coaxially arranged. The active member 36 meshes with the driven member 37. The active member 36 can be a driving gear, and the driven member 37 can be a driven gear. The active member 36 is suitable for being driven to drive the first sub-pump body 2A and the second sub-pump body 2B to rotate.

[0066] When the active member 36 is driven, the active member 36 and the driven member 37 are meshed, so that the driven member 37 can be driven to rotate, thereby driving the active member 36 to rotate and driving the driven member 37 to rotate, so that the meshing power transmission between the first sub-pump body 2A and the second sub-pump body 2B through the active member 36 and the driven member 37 can be ensured, and the first sub-pump body 2A and the second sub-pump body 2B can be easily driven to rotate, and there may be no meshing transmission relationship between the first sub-pump body 2A and the second sub-pump body 2B, that is, there is no need to consider whether one movement of the first sub-pump body 2A and the second sub-pump body 2B can drive the other movement of the first sub-pump body 2A and the second sub-pump body 2B. Therefore, when designing the structure of the first sub-pump body 2A and the second sub-pump body 2B, the structure of the first sub-pump body 2A and the second sub-pump body 2B can be simplified, the design restrictions on the structure of the first sub-pump body 2A and the second sub-pump body 2B are reduced, and the processing accuracy requirements of the first sub-pump body 2A and the second sub-pump body 2B are also relatively low.

[0067] In some embodiments of the present invention, reference Figure 1-Figure 6 The transmission assembly further includes: a driving button 31 and a transmission mechanism, the transmission mechanism is transmissionably arranged between the driving button 31 and the active member 36, when the driving button 31 is pressed, the driving button 31 drives the transmission mechanism to move, and the transmission mechanism transmits force to the active member 36, thereby driving the active member 36 to rotate, and through the engagement of the active member 36 with the driven member, the driven member is driven to rotate, thereby realizing the movement of the pump body 2, and then the dispensing device 100 can dispense the lotion 400. By providing the driving button 31 and the transmission mechanism transmissionably arranged between the driving button 31 and the active member 36, the user can conveniently realize the driving of the dispensing pump 10 by pressing the driving button 31, thereby conveniently realizing the semi-automatic dispensing of the lotion 400.

[0068] In some optional embodiments of the present invention, referring to Figure 1-Figure 6 The transmission mechanism may include a transmission member 33 and a driving gear, the transmission member 33 and the driving gear are connected in a transmission manner, for example, the transmission member 33 may be a rack, the transmission member 33 is meshed with the driving gear, the driving gear is connected to one axial side of the active member 36, the driving gear and the active member 36 may be coaxially arranged, and the transmission member 33 and the driving button 31 are matched in a transmission manner. When the driving button 31 is pressed, the driving button 31 drives the transmission member 33 to move, thereby driving the driving gear to rotate, and then driving the active member 36 and the driven member 37 to rotate, and then the first sub-pump body 2A and the second sub-pump body 2B can be driven to rotate, so that the movement of the pump body 2 can be easily achieved by pressing the driving button 31.

[0069] In some embodiments of the present invention, reference Figure 1-Figure 6The transmission mechanism of the delivery pump 10 can be arranged on the left or right side of the housing 1 of the delivery pump 10, thereby reducing the occupancy of the delivery port 601 in the front and rear directions, and further reducing the impact on the use of the delivery port 601.

[0070] In some embodiments of the present invention, reference Figure 1-Figure 6 The driving button 31 of the dispensing pump 10 can be located at the upper front of the dispensing pump 10 , so that it is convenient for the user to press the driving button 31 .

[0071] In some embodiments of the present invention, reference Figure 1-Figure 6 The pressing surface 312 of the driving button 31 can extend downwardly in a direction from the back to the front. When the user presses the driving button 31, the user's hand contacts the pressing surface 312 of the driving button 31, so that the user can apply pressure to the driving button 31 in a direction toward the back and bottom, which is convenient for the user to operate and press the driving button 31.

[0072] In some embodiments of the present invention, referring to Figure 1-Figure 6 Combined with Figure 9-13 The driving button 31 can move between the initial position and the delivery position. The user can apply force to the driving button 31 to move the driving button 31 from the initial position to the delivery position. In the process of the driving button 31 moving from the initial position to the delivery position, the movement of the driving button 31 drives the transmission mechanism to move, and the transmission mechanism drives the pump body 2 to move, so that the delivery device 100 can semi-automatically deliver the lotion 400. In the process of the driving button 31 moving from the initial position to the delivery position, a single delivery of the lotion 400 can be achieved.

[0073] After the driving button 31 moves to the delivery position, the driving button 31 can automatically reset to the initial position. The driving button 31 can also reset to the initial position under the reverse force of the user, that is, the driving button 31 can also be manually reset to the initial position. The following takes the automatic reset of the driving button 31 as an example to explain the reset of the driving button 31.

[0074] For example, in some embodiments of the present invention, reference Figure 1-Figure 6The transmission assembly also includes an elastic reset member 32, which can be a spring. The elastic reset member 32 is used to drive the driving button 31 to return to the initial position after the external force applied by the user is eliminated. It can be understood that when the driving button 31 moves from the initial position to the placement position under the action of the external force applied by the user, the elastic reset member 32 can produce elastic deformation and apply a reverse elastic reset force to the driving button 31. When the user no longer applies external force to the driving button 31, the driving button 31 can be reset to the initial position under the action of the elastic reset force applied by the elastic reset member 32. As a result, the user is no longer required to manually reset the driving button 31, thereby improving the convenience of user use.

[0075] In some optional embodiments of the present invention, the transmission assembly includes the above-mentioned driving button 31, a transmission mechanism, an active member 36 and a driven member. The transmission mechanism includes a one-way transmission mechanism, which is transmission-connected between the driving button 31 and the active member 36, and the driving button 31 can move between the initial position and the delivery position. In the process of the driving button 31 moving from the initial position to the delivery position, the driving button 31 drives the active member 36 to move through the one-way transmission mechanism, and the active member 36 drives the pump body 2 to move, specifically, drives the first sub-pump body 2A and the second sub-pump body 2B to rotate, so that the delivery device 100 delivers the lotion 400; in the process of the driving button 31 moving from the delivery position to the initial position, the one-way transmission mechanism no longer transmits force to the active member 36, so that the pump body 2 will not be driven to move, specifically, the first sub-pump body 2A and the second sub-pump body 2B will not be driven to rotate. This is conducive to avoiding reverse suction of the lotion 400 through the liquid outlet 112, and is conducive to ensuring the accuracy of the delivery of the lotion 400.

[0076] In some embodiments of the present invention, the one-way transmission mechanism is a one-way rotation mechanism, wherein, in the process of the driving button 31 moving from the initial position to the delivery position, the one-way transmission mechanism rotates along the first rotation direction driven by the driving button 31, drives the pump body 2 to move, and enables the delivery device 100 to deliver the lotion 400; in the process of the driving button 31 moving from the delivery position to the initial position, the one-way transmission mechanism rotates along the second rotation direction opposite to the first rotation direction, and the one-way transmission mechanism no longer transmits force to the pump body 2, thereby not driving the pump body 2 to move.

[0077] In some optional embodiments of the present invention, the first sub-pump body 2A and the second sub-pump body 2B can both rotate, and the transmission assembly includes the above-mentioned drive button 31, a transmission mechanism, an active member 36 and a driven member 37, wherein the transmission mechanism includes a mutually meshing transmission member 33 and a driving gear and a one-way transmission mechanism. The one-way transmission mechanism is a one-way rotation mechanism, and the one-way transmission mechanism includes a one-way transmission wheel, the active member 36 is a driving gear, and the driven member 37 is a driven gear. The active member 36 is connected to the first sub-pump body 2A, and the active member 36 is connected to one axial side of the first sub-pump body 2A, and the active member 36 and the first sub-pump body 2A can be coaxially arranged. The driven member is connected to the second sub-pump body 2B, and the driven member is connected to one axial side of the second sub-pump body 2B, and the driven member and the second sub-pump body 2B can be coaxially arranged.

[0078] A matching cavity is provided inside the active member 36, the one-way transmission wheel is located in the matching cavity, the driving gear and the one-way transmission wheel are coaxially arranged and relatively fixed, the driving gear is located on the axial side of the one-way transmission wheel away from the active member 36, and the driving gear is located outside the matching cavity. When the one-way transmission wheel rotates along a first rotation direction, the one-way transmission wheel abuts against the inner wall of the matching cavity to drive the active member 36 to rotate; when the one-way transmission wheel rotates along a second rotation direction opposite to the first rotation direction, the one-way transmission wheel is disengaged from the inner wall of the matching cavity. Among them, "the one-way transmission wheel is disengaged from the inner wall of the matching cavity" can be understood as that the one-way transmission wheel does not transmit the force to the inner wall of the matching cavity to drive the active member 36 to rotate, for example, the one-way transmission wheel is separated from the inner wall of the matching cavity, or, although the one-way transmission wheel is in contact with the matching cavity, the one-way transmission wheel cannot drive the active member to rotate through the inner wall of the matching cavity. By locating the one-way transmission wheel in the matching cavity of the active member 36, the space occupied by the active member 36 and the one-way transmission mechanism as a whole can be reduced. At the same time, the one-way transmission wheel abuts or separates from the inner wall of the matching cavity, which is conducive to ensuring the reliability of the one-way transmission of the one-way transmission mechanism.

[0079] In some embodiments of the present invention, reference Figure 1-Figure 3 The dispensing device 100 may further include: the nozzle body 50 has a storage chamber 53 for storing the lotion 400, the dispensing pump 10 is arranged on the nozzle body 50, and the driving button 31 can connect the liquid inlet 111 of the dispensing pump 10 with the storage chamber 53. When the dispensing device 100 is working, the lotion 400 in the storage chamber 53 enters the dispensing pump 10 through the liquid inlet 111, and the lotion 400 entering the dispensing pump 10 is driven to the liquid outlet 112 to be discharged from the dispensing pump 10 through the driving action of the pump body 2.

[0080] Optionally, the dispensing device 100 may further include an exterior component 40, which is disposed on the nozzle body 50 and located on the front side of the dispensing pump 10. The exterior component 40 has an installation channel 41 for installing and accommodating a driving button 31. The driving button 31 can be movably disposed in the installation channel 41. For example, the driving button 31 can be swingably disposed in the installation channel 41 or movably disposed in the installation channel 41.

[0081] For example, in some embodiments of the present invention, reference Figure 1-Figure 3 The nozzle body 50 has a mixing chamber 51, and the mixing chamber 51 and the storage chamber 53 are located at opposite sides of the delivery pump 10. For example, the mixing chamber 51 can be located at the front side of the delivery pump 10, and the storage chamber 53 can be located at the rear side of the delivery pump 10. The above-mentioned exterior component 40 can be arranged on the nozzle body 50 and located in front of the delivery pump 10, and the exterior component 40 can be located above the mixing chamber 51. The lotion 400 discharged from the liquid outlet 112 of the delivery pump 10 can flow into the mixing chamber 51. The nozzle body 50 is also formed with a water inlet connected to the mixing chamber 51, and a water inlet pipe is connected to the water inlet. A water inlet valve is arranged in the water inlet pipe. After the water inlet valve is opened, water can enter the mixing chamber 51 through the water inlet and fully mix with the lotion 400 flowing into the mixing chamber 51, and then flow into the washing chamber after mixing.

[0082] In some optional embodiments of the present invention, referring to Figure 1-Figure 3 , the delivery device 100 includes a plurality of delivery pumps 10 arranged along the second direction, for example, the plurality of delivery pumps 10 can be arranged along the left-right direction, thereby reducing the space occupied in the front-back direction of the delivery port 601, and further reducing the impact on the use of the delivery port 601. The nozzle body 50 has a plurality of storage chambers 53, the number of which is the same as the number of delivery pumps 10 and corresponds one to one. When the delivery pump 10 corresponding to each storage chamber 53 is working, the delivery pump 10 corresponding to each storage chamber 53 sucks the lotion 400 in the storage chamber 53 into the delivery pump 10 through the liquid inlet 111 of the delivery pump 10, and discharges it through the liquid outlet 112 of the delivery pump 10. Different types of lotions 400 can be stored in each storage chamber 53 as needed to meet more washing needs of users.

[0083] The nozzle body 50 may be formed with one mixing chamber 51 or with multiple mixing chambers 51. When there is one mixing chamber 51 on the nozzle body 50, when one of the delivery pumps 10 is working, the liquid outlet 112 of the delivery pump 10 is connected to the mixing chamber 51, and the liquid outlets 112 of the other delivery pumps 10 are all cut off from the mixing chamber 51, that is, the liquid outlet 112 of the working delivery pump 10 is connected to the mixing chamber 51, and the liquid outlet 112 of the non-working delivery pump 10 is cut off from the mixing chamber 51. When the nozzle body 50 has multiple mixing chambers 51, the number of the multiple mixing chambers 51 may be the same as the number of delivery pumps 10 and correspond one to one. When each delivery pump 10 is working, the lotion 400 discharged from the liquid outlet 112 may flow into the corresponding mixing chamber 51, and flow into the washing chamber after mixing with the water flow in the mixing chamber 51.

[0084] Furthermore, a plurality of installation channels 41 arranged at intervals along the second direction are formed on the exterior component 40, and a driving button 31 is provided in each installation channel 41. The number of driving buttons 31 is the same as the number of delivery pumps 10 and corresponds one to one. Each driving button 31 can drive the corresponding delivery pump 10 to work. When a delivery pump 10 needs to work, the corresponding driving button 31 can be pressed.

[0085] In some embodiments of the present invention, reference Figure 1-Figure 6 The driving button 31 moves in a straight line under the external force applied by the user. Thus, the movement route of the driving button 31 is simple, and the operation control is convenient, for example, tilt pressing can be conveniently realized.

[0086] In some embodiments of the present invention, reference Figure 1-Figure 6 The delivery device 100 includes: an exterior component 40, which can be located at the front side of the delivery pump 10, and an appearance surface 42 is formed at the front side of the exterior component 40. The exterior component 40 has a mounting channel 41 for accommodating the driving button 31. The driving button 31 slides with the mounting channel 41. The setting of the mounting channel 41 can play a role in positioning and guiding the movement of the driving button 31. The driving button 31 moves in the mounting channel 41 to achieve the function of driving the delivery pump 10. The mounting channel 41 extends downwardly in a direction from front to back, and the front end of the mounting channel 41 passes through the appearance surface 42. The driving button 31 is suitable for being pressed and moving along the mounting channel 41. When the driving button 31 is pressed, the driving button 31 is suitable for moving backward and in a downwardly inclined direction away from the appearance surface 42.

[0087] When the dispensing device 100 is used in a clothing processing device, the user can drive the dispensing pump 10 by pressing the driving button 31 obliquely downward. Since the user can reduce the pressing force with the help of gravity when applying pressure obliquely downward, it is more ergonomic, making the force application process more comfortable and the operation feel better. In addition, in the limited installation space of the workbench 600, the driving button 31 moves in the direction of backward and oblique downward, which can also increase the stroke of the driving button 31 in the limited installation space. Since the amount of lotion 400 is related to the stroke of the driving button 31, the longer the stroke, the greater the amount of dispensing. Therefore, the obliquely moving driving button 31 achieves the dispensing of a larger dose of lotion 400. Furthermore, among the driving buttons 31 with the same movement stroke, the driving button 31 that moves in the direction of oblique downward toward the inside of the exterior component 40 has a smaller displacement in the vertical direction, thereby avoiding the phenomenon of getting stuck during operation and improving the operation experience.

[0088] By moving the driving button 31 toward the rear and tilted downward, the amount of detergent 400 that can be dispensed by driving the dispensing pump 10 in one operation of the driving button 31 can be increased, the number of operations required for dispensing the detergent 400 can be reduced, and the user's pressing experience can also be taken into account, the operating force can be reduced, and the phenomenon of getting stuck during operation can be avoided, thereby improving the operating experience.

[0089] Specifically, refer to Figure 1-Figure 7 In order to facilitate user operation, the driving button 31 of the dispensing device 100 is arranged forward to meet the user's operating habits. Specifically, the installation channel 41 extends downward from front to back, that is, the angle between the installation channel 41 and the horizontal direction is greater than 0° and less than 90°. When the user presses the driving button 31, the driving button 31 moves backward and downward, so that the dispensing device 100 dispenses the lotion 400. Accordingly, the driving button 31 extends downward from front to back. Specifically, the angle between the driving button 31 and the horizontal direction is greater than 0° and less than 90°, thereby making the user's operating space larger, so that the user can press the driving button 31 easily, avoid getting stuck in the process of pressing the driving button 31, and improve the user experience.

[0090] In some embodiments of the present invention, reference Figure 3-Figure 6 In the direction from the exterior surface 42 to the dosing pump 10, the cross-sectional area of ​​the installation channel 41 gradually expands. In this way, when the user presses the driving button 31 to move, the gap between the driving button 31 and the inner wall of the installation channel 41 gradually increases, making the movement of the driving button 31 smoother during the pressing process, and improving the operating feel of the driving button 31.

[0091] In some embodiments of the present invention, reference Figure 1-Figure 6The appearance surface 42 is tilted forward from top to bottom, which not only makes it convenient for the user to observe the patterns, marks and other contents on the appearance surface 42, but also enables the user to operate in the space in front of the delivery device 100. In addition, the forward tilt of the appearance surface 42 shortens the distance between the user and the driving button 31, making it easier to operate.

[0092] In some embodiments of the present invention, reference Figure 1-Figure 6 The driving button 31 is movable between an initial position and a delivery position. The driving button 31 is suitable for moving from the initial position toward a direction away from the appearance surface 42 to the delivery position under the action of pressing. Specifically, the driving button 31 is moved backward and downward from the initial position to the delivery device 100 under the action of pressing. When the driving button 31 moves to the delivery position, the delivery device 100 delivers the lotion 400.

[0093] Optionally, in the initial position, the pressing surface 312 of the driving button 31 is flush with the appearance surface 42, which can reduce the space occupied by the driving button 31, making the appearance of the delivery device 100 smoother and improving the aesthetics.

[0094] Optionally, in the initial position, a portion of the driving button 31 protrudes from the exterior surface 42, and at this time, the pressing surface 312 of the driving button 31 is located in the front upper part of the exterior surface 42. The user presses the protruding portion of the driving button 31 to move the driving button 31 along the installation channel 41, thereby making the driving button 31 more operable and more convenient for the user to apply force to the driving button 31.

[0095] In some optional embodiments of the present invention, referring to Figure 1-Figure 6 The transmission mechanism includes: a transmission member 33, the transmission member 33 is transmissionably connected to the active member 36, the transmission member 33 is suitable for abutting with the driving button 31, and when the driving button 31 is pressed, the driving button 31 drives the transmission member 33 to move downwardly in a direction from front to back. For example, one end of the transmission member 33 close to the appearance surface 42 cooperates with the driving button 31, so that when the user presses the driving button 31, the transmission member 33 can be driven to move downwardly in a direction from front to back. The transmission member 33 is also transmission-coordinated with the delivery pump 10, so that when the transmission member 33 moves, the delivery pump 10 can be driven to pump out the lotion 400. Through the transmission member 33, when the driving button 31 is pressed, the force can be conveniently transmitted to the delivery pump 10 to drive the delivery pump 10 to move, thereby delivering the lotion 400.

[0096] In some specific embodiments of the present invention, referring to Figure 1-Figure 6The driving button 31 has a matching groove 311 on one side close to the transmission member 33, and the transmission member 33 has a matching plate 331 that is abutted against the matching groove 311. The driving button 31 and the transmission member 33 are abutted against each other through the matching groove 311 and the matching plate 331, so that the matching transmission can be completed when the driving button 31 and the transmission member 33 are separated. The side wall of the matching groove 311 can limit the matching plate 331 to ensure the stability of the setting of the transmission member 33. When the driving button 31 is pressed, the inner wall of the matching groove 311 can push the matching plate 331, so that the transmission member 33 moves along with the movement of the driving button 31.

[0097] In some optional embodiments of the present invention, referring to Figure 1-Figure 6 The transmission member 33 may include a driving rack 332, which may extend obliquely downward in the direction from front to back, and the transmission mechanism may also include a driving gear, which is meshed with the driving rack 332, and the driving gear is connected to one axial side of the active member 36. When the driving button 31 is pressed, the driving button 31 drives the transmission member 33 to move backward and obliquely downward. Since the driving button 31 and the transmission member 33 are stopped and matched, the transmission member 33 may be driven to move backward and obliquely downward. Since the driving rack 332 of the transmission member 33 is meshed with the driving gear provided on the active member 36, the driving gear is driven to rotate, and then the active member 36 and the driven member are driven to rotate, and then the first sub-pump body 2A and the second sub-pump body 2B can be driven to rotate, and the movement of the pump body 2 can be driven by pressing the driving button 31 to achieve the delivery of the lotion 400.

[0098] In a further embodiment of the present invention, referring to Figure 1-Figure 6 The delivery device 100 further includes: a valve component 60. The delivery device 100 may include a nozzle body 50 and a storage chamber 53. The nozzle body 50 has the above-mentioned mixing chamber 51. The nozzle body 50 is also formed with a delivery hole 52 suitable for communicating with the mixing chamber 51. The valve component 60 is movably arranged at the delivery hole 52 to open or close the delivery hole 52. For example, the valve component 60 is movably arranged at the delivery hole 52 to open and close the delivery hole 52. When the valve component 60 opens the delivery hole 52, the liquid outlet 112 of the delivery pump 10 is communicated with the mixing chamber 51 through the delivery hole 52. When the delivery pump 10 is working, the lotion 400 pumped out from the delivery pump 10 flows into the mixing chamber 51 from the liquid outlet 112 and the delivery hole 52; when the valve component 60 closes the delivery hole 52, the liquid outlet 112 of the delivery pump 10 is separated from the mixing chamber 51. By controlling the valve member 60 to move at the delivery hole 52, the opening and closing of the delivery hole 52 can be controlled. Thus, by controlling the opening and closing of the delivery hole 52, the delivery amount of the lotion 400 can be better controlled to achieve a better delivery effect.

[0099] Among them, the liquid outlet 112 of the dosing pump 10 can be located above the dosing hole 52, so that the lotion 400 dispensed by the dosing pump 10 can flow downward under the action of gravity and enter the mixing chamber 51 through the dosing hole 52, thereby preventing the lotion 400 from being retained in the dosing pump 10.

[0100] In some optional embodiments of the present invention, referring to Figure 1-Figure 6 , the driving button 31 can drive the valve component 60 to open the delivery hole 52 while driving the delivery pump 10 to work, and the detergent 400 pumped out by the delivery pump 10 can directly enter the mixing chamber 51 through the opened delivery hole 52, thereby achieving the delivery of the detergent 400. That is to say, the valve component 60 and the delivery pump 10 can be driven to work together by one driving button 31, which reduces the number of driving structures in the delivery device 100, makes the overall structure of the delivery device 100 simpler, reduces the manufacturing cost, and because the valve component 60 and the delivery pump 10 work at the same time, the valve component 60 will open the delivery hole 52 when the detergent 400 needs to be delivered, avoiding the leakage of the delivery device 100, making the device as a whole more reliable. In addition, because the valve component 60 and the delivery pump 10 work together, the treatment agent can be delivered intermittently during the washing process, and no leakage will occur during the delivery process, thereby improving the washing effect of the clothing treatment device.

[0101] In some specific embodiments of the present invention, the transmission member 33 has a driving surface 333, and the driving surface 333 can be slidably matched with the top of the valve component 60. When the driving button 31 is pressed, the driving button 31 moves backward and tilted downward, and drives the transmission member 33 to move backward and tilted downward, and the driving surface 333 of the transmission member 33 drives the valve component 60 to move downward to open the delivery hole 52. When the driving button 31 is in the initial position, the driving surface 333 is located above the valve component 60 and extends tilted downward in a direction close to the valve component 60.

[0102] It can be understood that, in the initial position, the contact point between the driving surface 333 of the transmission member 33 and the valve component 60 is at the highest position, and as the driving button 31 moves obliquely downward along the installation channel 41, the contact point between the driving surface 333 of the transmission member 33 and the valve component 60 gradually decreases, thereby causing the valve component 60 to move downward under the drive of the driving button 31, thereby, the driving surface 333 can convert the oblique downward movement trend of the transmission member 33 into the downward movement trend of the valve component 60, pushing the valve component 60 to move downward to open the injection hole 52. The valve component 60 can be reset under the action of the reset member, for example, the valve component 60 can be moved upward and reset to the initial position under the action of the reset member.

[0103] Combine the following Figure 4-Figure 6 as well as Figure 8-Figure 13 The process of pressing the driving button 31 to drive the dispensing pump 10 to work is described.

[0104] Reference Figure 4 , Figure 4 It is a partial schematic diagram of the delivery device 100 when it is in the initial position. At this time, a part of the driving button 31 protrudes from the appearance surface 42, the matching groove 311 of the driving button 31 and the matching plate 331 of the transmission member 33 are stop-fitted, and the driving surface 333 of the transmission member 33 and the valve component 60 are slidingly matched. At the same time, the transmission member 33 is also transmission-matched with the delivery pump 10, and the valve component 60 closes the delivery hole 52.

[0105] Reference Figure 5 When the driving button 31 is pressed, the driving button 31 moves backward and tilted downward from the initial position. The driving button 31 is suitable for moving backward and tilted downward along the installation channel 41. Under the action of the matching groove 311 of the driving button 31 and the matching plate 331 of the transmission member 33, the driving button 31 drives the transmission member 33 to move backward and tilted downward along the installation channel 41. The driving surface 333 of the transmission member 33 is suitable for accompanying the transmission member 33 to move obliquely downward. Since the driving surface 333 is located above the valve component 60 and extends obliquely downward in the direction close to the valve component 60, the driving surface 333 is suitable for accompanying the transmission member 33 to move obliquely downward. The downward movement trend will be transmitted to the valve component 60, so that the valve component 60 moves downward and opens the delivery hole 52. In addition, during the movement of the transmission member 33, the delivery pump 10 is driven, so that the delivery pump 10 performs the delivery action.

[0106] Reference Figure 6 , further press the driving button 31 so that the driving button 31 is pressed to the delivery position. Under the action of the matching groove 311 of the driving button 31 and the matching plate 331 of the transmission member 33, the transmission member 33 moves to the delivery position at the same time. At this time, the valve component 60 moves to the lowest point under the drive of the transmission member 33, opens the delivery hole 52, and the delivery pump 10 also completes a complete delivery action under the drive of the transmission member 33. The delivery pump 10 drives the lotion 400 in the storage chamber 53 to enter the delivery pump 10 through the liquid inlet 111, and is discharged to the mixing chamber 51 through the liquid outlet 112 and the delivery hole 52, and flows into the washing chamber after mixing with the water flow.

[0107] After the dispensing of the lotion 400 is completed, the pressing of the driving button 31 is stopped, and the external force on the driving button 31 disappears. At this time, the driving button 31 moves forward and obliquely upward to reset to the initial position under the action of the elastic reset member 32. At the same time, the downward force of the driving button 31 on the valve component 60 disappears, and the valve component 60 moves upward to reset to the initial position. In the process of the valve component 60 moving upward to reset, the transmission member 33 is driven to move forward and obliquely upward to reset to the initial position, and the valve component 60 moves upward until the dispensing hole 52 is closed.

[0108] Refer to the following Figure 1-Figure 3 as well as Figure 8-Figure 13 A dosing pump 10 according to an embodiment of the present invention is described.

[0109] The dosing pump 10 includes a housing 1 and a pump body 2. The housing 1 is formed with a liquid inlet 111 and a liquid outlet 112. The pump body 2 is movably arranged in the housing 1. The pump body 2 includes a first sub-pump body 2A and a second sub-pump body arranged along a first direction. The first sub-pump body 2A and the second sub-pump body 2B are arranged in cooperation with each other. A plurality of mutually separated compartments 113 are defined between the first sub-pump body 2A and the second sub-pump body 2B and the inner wall surface of the housing 1. The lotion is suitable for entering the compartments 113 from the liquid inlet 111 and being discharged from the liquid outlet 112. The compartments 113 are used for temporarily storing and transporting the lotion 400.

[0110] Among them, the first sub-pump body 2A and the second sub-pump body 2B are arranged to cooperate with each other, which means that through the mutual cooperation of the two first sub-pump bodies 2A and the second sub-pump bodies 2B, a plurality of mutually separated grid areas 113 are defined between the first sub-pump body 2A and the second sub-pump body 2B and the inner wall surface of the shell 1, and during the movement of the first sub-pump body 2A and the second sub-pump body 2B, through the mutual cooperation of the first sub-pump body 2A and the second sub-pump body 2B, the movement of the first sub-pump body 2A and the second sub-pump body 2B will not interfere with each other, thereby ensuring the smooth movement of the first sub-pump body 2A and the second sub-pump body 2B, and there is no transmission relationship between the first sub-pump body 2A and the second sub-pump body 2B, that is, the movement of one of the first sub-pump body 2A and the second sub-pump body 2B will not drive the movement of the other one of the first sub-pump body 2A and the second sub-pump body 2B.

[0111] It should be noted that the “plurality” mentioned in the present invention refers to two or more than two.

[0112] The transmission assembly is connected to the pump body 2 to drive the first sub-pump body 2A and the second sub-pump body 2B to move. Through the movement of the first sub-pump body 2A and the second sub-pump body 2B and the mutual cooperation of the first sub-pump body 2A and the second sub-pump body 2B, the lotion 400 can be sucked into the compartment 113 in the shell 1 from the liquid inlet 111. During the continued rotation of the first sub-pump body 2A and the second sub-pump body 2B, the first sub-pump body 2A and the second sub-pump body 2B drive the lotion 400 located in the compartment 113 to flow toward the liquid outlet 112, and finally can be discharged from the liquid outlet 112.

[0113] Specifically, the first sub-pump body 2A and the second sub-pump body 2B move under the drive of the transmission assembly. During the movement of the first sub-pump body 2A and the second sub-pump body 2B, the first sub-pump body 2A and the second sub-pump body 2B cooperate with each other to generate negative pressure near the liquid inlet 111, and liquid such as lotion 400 can enter the compartment 113 in the housing 1 through the liquid inlet 111 under the action of negative pressure and its own gravity. Since the first sub-pump body 2A and the second sub-pump body 2B move under the drive of the transmission assembly, the lotion 400 entering the compartment 113 moves to the liquid outlet 112 under the push of the moving first sub-pump body 2A and the second sub-pump body 2B. When the lotion 400 is brought to the liquid outlet 112, the movement and cooperation of the first sub-pump body 2A and the second sub-pump body 2B can squeeze out the liquid in the compartment 113 and finally discharge it from the liquid outlet 112.

[0114] In this embodiment, the lotion 400 is sucked into the compartment 113 from the liquid inlet 111, and the lotion 400 in the compartment 113 is brought to the liquid outlet 112 by the movement of the first sub-pump body 2A and the second sub-pump body 2B. In this process, the role of the transmission component is to drive the first sub-pump body 2A and the second sub-pump body 2B to move, and transfer the lotion in the compartment 2 from the liquid inlet 111 to the liquid outlet 112, and the process of the washing 60 being sucked into the liquid inlet 111 and the washing 60 being discharged from the liquid outlet 112 is achieved by the movement of the first sub-pump body 2A and the second sub-pump body 2B and the mutual cooperation. Therefore, in this application, by setting a transmission component to drive the two sub-pump bodies to move, the moving sub-pump bodies promote the suction and discharge of liquid, which reduces the force required on the transmission component.

[0115] In this embodiment, a plurality of mutually separated compartments 113 are defined between the first sub-pump body 2A and the second sub-pump body 2B and the inner wall surface of the housing 1 , and these compartments 113 are used for temporarily storing and transporting the lotion 400 .

[0116] It is understandable that when the dispensing device 100 is in the initial state (there is no lotion 400 in the compartment 113), when the transmission component drives the pump body 2 to move, negative pressure can be generated at the liquid inlet 111, and the lotion 400 is sucked into the compartment 113 in the housing 1 through the liquid inlet 111, and the lotion 400 is transported to the liquid outlet 112 by the pushing action of the pump body 2, and discharged from the liquid outlet 112. In this process, the liquid suction at the liquid inlet 111 and the liquid discharge at the liquid outlet 112 are not synchronized in time until the lotion 400 can be discharged from the liquid outlet 112. After that, that is, when the dispensing device 100 is working normally, when the transmission component drives the pump body 2 to move to dispense the lotion 400, the liquid suction at the liquid inlet 111 and the liquid discharge at the liquid outlet 112 are synchronized in time.

[0117] Moreover, a plurality of grid areas 113 are defined between the pump body 2 and the inner wall surface of the shell 1. During the process of the dispensing device 100 dispensing the lotion 400, the volume of the lotion 400 temporarily contained in a single grid area 113 can be determined by limiting the volume of the grid area 113. The amount of lotion 400 dispensed by the user at a time can be the amount of lotion 400 contained in a single grid area 113, thereby making the amount of lotion 400 dispensed at a time more accurate.

[0118] For example, in some examples of the present invention, reference Figure 8-Figure 13 ( Figure 9-13 The process of liquid inflow and liquid discharge in one of the compartments 113 is shown. Fig. 9 One of the compartments 113 is shown as being filled with liquid. Fig.10 and Fig.11 It shows that the liquid in the compartment 113 moves toward the direction of the adjacent liquid outlet under the drive of the pump body 2, that is, the process of transporting the liquid. Fig.12 and Fig.13 The drainage process is shown. Fig.13 113). When the pump body 2 moves to the point where one of the sub-areas 113 is connected to the liquid inlet 111 on the housing 1, the lotion 400 can flow into the sub-area 113 through the liquid inlet 111. As the pump body 2 continues to move, the lotion 400 in the sub-area 113 is pushed toward the liquid outlet 112 by the pump body 2. When the pump body 2 moves to the point where the sub-area 113 is connected to the liquid outlet 112, the lotion 400 in the sub-area 113 is discharged through the liquid outlet 112, so that the amount of lotion 400 dispensed at a time is the same as the volume of a single sub-area 113, thereby improving the accuracy of the lotion 400 dispensed at a time.

[0119] According to the embodiment of the present invention, the dispensing device 100 is provided with a pump body 2, and a plurality of compartments 113 are defined between the pump body 2 and the inner wall surface of the shell 1, and the pump body 2 is configured to include two first sub-pump bodies 2A and second sub-pump bodies 2B that cooperate with each other. When the dispensing device 100 is working normally, the first sub-pump body 2A and the second sub-pump body 2B are driven to move by the transmission assembly, so that the lotion 400 can be sucked into the compartments 113 from the liquid inlet 111, and the lotion 400 in the compartments 113 can be brought to the liquid outlet 112 for discharge through the movement of the pump body 2.

[0120] In addition, since a plurality of sub-areas 113 are defined between the pump body 2 and the inner part of the housing 1, it is possible to achieve that while one sub-area 113 is sucking liquid, another sub-area 113 is draining liquid, so that the suction and draining of liquid are synchronized in time, and the space utilization efficiency in the sub-area 113 is improved, which is conducive to increasing the amount of detergent delivered in a single transportation. Furthermore, since the number of sub-areas 113 can be set and the capacity of each sub-area 113 is controllable, the delivery accuracy requirement can be guaranteed.

[0121] In existing pump structures, such as gear pumps, the gears must realize both the transmission function and the liquid delivery function. The transmission function requires that the tooth gap cannot be set too large, otherwise it will affect the transmission effect. The present invention, however, sets a separate partition 2 for liquid transmission, and the partition 2 itself does not require meshing transmission. Therefore, the partition area 113 can be set larger to achieve the effect of increasing the single infusion volume.

[0122] According to some embodiments of the present invention, referring to Figure 3 , Figure 8-Figure 13 , the sub-grid area 113 extends in a direction perpendicular to the arrangement direction of the first sub-pump body 2A and the second sub-pump body 2B. For example, the first sub-pump body 2A and the second sub-pump body 2B can be arranged in the up-down direction, and the sub-grid area 113 can extend in the left-right direction. By making the extension direction of the sub-grid area 113 perpendicular to the arrangement direction of the first sub-pump body 2A and the second sub-pump body 2B, it can be ensured that the extension space of the sub-grid area 113 does not affect the movement space of the transmission component, so that the space utilization rate inside the delivery device 100 is optimized and the structure is more compact.

[0123] According to some embodiments of the present invention, referring to Figure 1-Figure 3 as well as Figure 8, the first sub-pump body 2A is rotatable, and the rotation axis of the first sub-pump body 2A extends along the second direction (for example, refer to the left and right direction in the accompanying drawings), and the second sub-pump body 2B is rotatable, and the rotation axis of the second sub-pump body 2B extends along the second direction, and the second direction is perpendicular to the first direction. By rotating the first sub-pump body 2A and the second sub-pump body 2B, the suction and discharge of the lotion 400 can be achieved. In addition, the grid area 113 can be formed into a channel extending along the second direction, and the volume of the grid area 113 can be increased, so that the single delivery amount can be increased. In addition, by making the rotation axes of the first sub-pump body 2A and the second sub-pump body 2B extend in a direction perpendicular to the axial direction of the inner barrel 500, it is further conducive to realizing the tilting and pressing of the delivery device 100, which is convenient for users to operate the delivery device 100. In addition, through reasonable settings, the occupation of the delivery port 601 space can be further reduced.

[0124] Optionally, the plane where the rotation axis of the first sub-pump body 2A and the rotation axis of the second sub-pump body 2B are located is parallel to the first direction, that is, the plane where the rotation axis of the first sub-pump body 2A and the rotation axis of the second sub-pump body 2B are located extends along the axial direction of the inner barrel, so that the first sub-pump body 2A and the second sub-pump body 2B are symmetrically arranged along the axial direction of the inner barrel, further making full use of the axial space of the inner barrel, thereby making the arrangement of the first sub-pump body 2A and the second sub-pump body 2B more compact, further reducing the space occupied by the workbench 600.

[0125] According to some embodiments of the present invention, referring to Figure 3 , Figure 8-Figure 13 The first sub-pump body 2A and the second sub-pump body 2B are both rotatable, and the first sub-pump body 2A and the second sub-pump body 2B both include: a rotating portion 21 and a plurality of compartments 22, the plurality of compartments 22 can be arranged at intervals along the circumference of the rotating portion 21, and a compartment groove 23 can be defined between two adjacent compartments 22, and the inner wall surface of the compartment groove 23 can constitute a part of the inner wall surface of the compartment area 113. The compartment part 22 is extended along the axial direction of the rotating portion 21, so that the compartment groove 23 defined between the two compartments 22 can extend along the axial direction of the pump body, thereby increasing the volume of the compartment groove 23, and further, the outer peripheral contour of the first sub-pump body 2A and the second sub-pump body 2B and the inner wall of the shell 1 define the compartment area 113 extending along the axial direction of the pump body 2, which can effectively increase the volume of the compartment area 113.

[0126] For example, the first sub-pump body 2A and the second sub-pump body 2B are arranged in the up-down direction, the rotating parts 21 of the first sub-pump body 2A and the second sub-pump body 2B are extended in the left-right direction, and the grid parts 22 of the first sub-pump body 2A and the second sub-pump body 2B are extended in the left-right direction, so that the outer peripheral contour of the first sub-pump body 2A and the second sub-pump body 2B and the inner wall of the housing 1 define a grid area 113 extending in the left-right direction of the pump body. In the present application, in order to increase the amount of detergent delivered at a single time, the grid area 113 is set as an extended channel. The larger the channel of the grid area 113, the more detergent it can accommodate, and the more detergent is delivered at a single time.

[0127] According to some optional embodiments of the present invention, referring to Figure 3 , Figure 8-Figure 13 The first sub-pump body 2A and the second sub-pump body 2B each include: a rotating portion 21 and a plurality of compartments 22, the plurality of compartments 22 may be connected to the outer circumferential surface 212 of the rotating portion 21, the plurality of compartments 22 may be arranged at intervals along the circumference of the rotating portion 21, for example, the plurality of compartments 22 may be arranged at even intervals along the circumference of the rotating portion 21. A compartment groove 23 may be defined between each two adjacent compartments 22 in the first sub-pump body 2A and the second sub-pump body 2A, at least a portion of the compartment 22 of the first sub-pump body 2A is suitable for being accommodated in the compartment groove 23 of the second sub-pump body 2B, and / or at least a portion of the compartment 22 of the second sub-pump body 2B is suitable for being accommodated in the compartment groove 23 of the first sub-pump body 2A.

[0128] Reference Figure 3 , Figure 8-Figure 13 , during the rotation of the first sub-pump body 2A and the second sub-pump body 2B, at least a portion of the grid portion 22 of the first sub-pump body 2A may be suitable for being accommodated in the grid groove 23 of the second sub-pump body 2B in some stages, and at least a portion of the grid portion 22 of the second sub-pump body 2B may be suitable for being accommodated in the grid groove 23 of the first sub-pump body 2A in another stage. During the rotation of the first sub-pump body 2A and the second sub-pump body 2B, at least a portion of one of the grid portions 22 of the first sub-pump body 2A may be accommodated in one of the grid grooves 23 of the second sub-pump body 2B, or at least a portion of one of the grid portions 22 of the second sub-pump body 2B may be accommodated in one of the grid grooves 23 of the first sub-pump body 2A, so as to achieve mutual coordination and avoidance during the movement of the first sub-pump body 2A and the second sub-pump body 2B to avoid interference. In this way, during the rotation of the first sub-pump body 2A and the second sub-pump body 2B, the partition groove 23 of one of the first sub-pump body 2A and the second sub-pump body 2B can be used to avoid the partition part 22 of the other one, so as to avoid interference between the first sub-pump body 2A and the second sub-pump body 2B during the rotation, ensure the normal and smooth rotation of the first sub-pump body 2A and the second sub-pump body 2B, so as to realize the normal operation of the dispensing device 100.

[0129] In some optional embodiments of the present invention, referring to Figure 3 , Figure 8-Figure 13 The compartment portion 22 of one of the first sub-pump body 2A and the second sub-pump body 2B is adapted to contact the inner wall surface of the compartment groove 23 of the other of the first sub-pump body 2A and the second sub-pump body 2B.

[0130] Specifically, during the rotation of the first sub-pump body 2A and the second sub-pump body 2B, the first sub-pump body 2A and the second sub-pump body 2B can cooperate with each other in the following manner. During the rotation of the first sub-pump body 2A and the second sub-pump body 2B, the compartment groove 23 of the first sub-pump body 2A can avoid the compartment part 22 of the second sub-pump body 2B, that is, the compartment part 22 of the second sub-pump body 2B can be at least partially accommodated in the compartment groove 23 of the first sub-pump body 2A, and the compartment part 22 of the second sub-pump body 2B can contact the inner wall of the compartment groove 23 of the first sub-pump body 2A; the compartment groove 23 of the second sub-pump body 2B can avoid the compartment part 22 of the first sub-pump body 2A, that is, the compartment part 22 of the first sub-pump body 2A can be at least partially accommodated in the compartment groove 23 of the second sub-pump body 2B, and the compartment part 22 of the first sub-pump body 2A can contact the inner wall of the compartment groove 23 of the second sub-pump body 2B. This can better separate the multiple sub-areas 113, avoid or reduce the lotion 400 in one sub-area 113 from flowing into other sub-areas 113 through the gap between the first sub-pump body 2A and the second sub-pump body 2B, and ensure the accuracy of the single-time lotion dosage.

[0131] According to some optional embodiments of the present invention, referring to Figure 3 , Figure 8-Figure 13 The grid portion 22 has a first outer peripheral contour surface 2211, and the first outer peripheral contour surface 2211 extends along the circumference of the rotating portion 21. The first outer peripheral contour surface 2211 can be formed as an arc surface, that is, the first outer peripheral contour surface 2211 extends in an arc shape in the circumferential direction of the rotating portion 21. Therefore, during the rotation of the first sub-pump body 2A and the second sub-pump body 2B, the first sub-pump body 2A and the second sub-pump body 2B can rotate smoothly, avoiding interference between the first sub-pump body 2A and the second sub-pump body 2B and the inner wall of the housing 1, and the gap between the first outer peripheral contour surface 2211 of the first sub-pump body 2A and the second sub-pump body 2B and the inner circumferential surface of the housing 1 can be small or no gap, so that the lotion 400 between the grid areas 113 can be better prevented from leaking, and the accuracy of the amount of lotion 400 added at a single time can be ensured.

[0132] In some optional embodiments of the present invention, referring to Figure 3 , Figure 8-Figure 13The first outer peripheral contour surfaces 2211 of all the sub-cells 22 of the first sub-pump body 2A are located on the same cylindrical surface, and the first outer peripheral contour surfaces 2211 of all the sub-cells 22 of the second sub-pump body 2B are located on the same cylindrical surface. The sub-cell grooves 23 of the first sub-pump body 2A are formed by the concavity of part of the outer peripheral wall of the first base cylinder 20 toward the central axis direction of the adjacent first base cylinder 20, for example Figure 7 and Fig. 9 The dotted part of the outer circumferential contour line of the first base cylinder 20 is the outer circumferential contour line before the outer circumferential wall of the above-mentioned part is recessed, and the dotted part of the outer circumferential contour line of the first base cylinder 20 is recessed toward the inner wall surface of the partition groove 23, and the other outer circumferential walls 24 of the first base cylinder 20 form the first outer circumferential contour surface 2211 of the partition part 22 of the first sub-pump body 2A, so that the first outer circumferential contour surfaces 2211 of all the partition parts 22 of the first sub-pump body 2A are located on the cylindrical surface of the first base cylinder 20. During the processing and manufacturing process of the first sub-pump body 2A, it can be processed and manufactured from the first base cylinder 20. Specifically, part of the outer circumferential wall of the first base cylinder 20 can be recessed toward the central axis direction of the adjacent first base cylinder 20, and the part of the outer circumferential wall of the first base cylinder 20 recessed toward the central axis direction of the adjacent base cylinder 20 forms the above-mentioned partition groove 23, so that the structure of the first sub-pump body 2A is simple and convenient to process and manufacture, and the formation of the partition groove 23 is convenient, and the volume of the partition groove 23 is also large, which is conducive to forming a partition area 113 with a larger volume.

[0133] Similarly, the compartment groove 23 of the second sub-pump body 2B is formed by a portion of the outer peripheral wall of the first base cylinder 20 being recessed toward the central axis of the first base cylinder 20, for example Figure 7 and Fig. 9 The dotted part in the outer circumferential contour line of the first base cylinder 20 is the outer circumferential contour line before the outer circumferential wall of the above-mentioned part is recessed, and the dotted part in the outer circumferential contour line of the first base cylinder 20 is recessed toward the inner wall surface of the partition groove 23. The other outer circumferential walls 24 of the first base cylinder 20 form the first outer circumferential contour surface 2211 of the partition part 22 of the second sub-pump body 2B. The first outer circumferential contour surfaces 2211 of all the partition parts 22 of the second sub-pump body 2B are located on the cylindrical surface of the first base cylinder 20. During the processing and manufacturing process of the second sub-pump body 2B, it can be processed and manufactured from the first base cylinder 20. Specifically, part of the outer circumferential wall of the first base cylinder 20 can be recessed toward the central axis direction of the adjacent first base cylinder 20, and the part of the outer circumferential wall of the first base cylinder 20 recessed toward the central axis direction of the adjacent first base cylinder 20 forms the above-mentioned partition groove 23, so that the structure of the second sub-pump body 2B is simple and convenient to process and manufacture, and the formation of the partition groove 23 is convenient, and the volume of the partition groove 23 is also large, which is conducive to forming a partition area 113 with a larger volume.

[0134] In some specific embodiments of the present invention, the circumferential length of the first outer peripheral contour surface 2211 is 1 / 4 of the circumference of the first base cylinder 20, so that the circumferential extension length of the first outer peripheral contour surface 2211 is larger, thereby increasing the matching area between the first outer peripheral contour surface 2211 and the inner circumferential surface of the shell 1, and further reducing the leakage of the lotion 400 between adjacent grid areas 113 through the gap between the first outer peripheral contour surface 2211 and the inner circumferential surface of the shell 1, which can better avoid the leakage of the lotion 400 between the grid areas 113 and ensure the accuracy of the amount of lotion 400 dosed at a single time.

[0135] In some optional embodiments of the present invention, the inner circumference of the shell 1 is formed as an arcuate surface, and the first outer circumferential contour surface 2211 is in sealed contact with the inner circumferential surface of the shell 1. By forming the inner circumferential surface of the shell 1 as an arcuate surface, the gap between the first outer circumferential contour surface 2211 and the inner circumferential surface of the shell 1 can be reduced, so that the first outer circumferential contour surface 2211 and the inner circumferential surface of the shell 1 can form a sealed contact along the circumferential direction of the shell 1, so as to better avoid the leakage of the lotion 400 between the sub-grid areas 113 and ensure the accuracy of the amount of lotion 400 added at a single time.

[0136] In some embodiments of the present invention, reference Figure 3 , Figure 8-Figure 13 The rotating part 21 of the first sub-pump body 2A further includes a second base cylinder 210, which is concentrically arranged with the first base cylinder 20, and the radius of the second base cylinder 210 is smaller than the radius of the first base cylinder 20, and at least a portion of the outer peripheral wall surface 213 of the second base cylinder 210 forms the outer peripheral surface 212 of the rotating part 21. Thus, the structure of the rotating part 21 of the first sub-pump body 2A is simple and easy to form, and the structure of the entire first sub-pump body 2A is simple and easy to manufacture.

[0137] In some embodiments of the present invention, reference Figure 3 , Figure 8-Figure 13 The rotating part 21 of the second sub-pump body 2B further includes a second base cylinder 210, which is concentrically arranged with the first base cylinder 20, and the radius of the second base cylinder 210 is smaller than the radius of the first base cylinder 20, and at least a portion of the outer peripheral wall surface 213 of the second base cylinder 210 forms the outer peripheral surface 212 of the rotating part 21. Thus, the structure of the rotating part 21 of the second sub-pump body 2B is simple and easy to form, and the structure of the entire second sub-pump body 2B is simple and easy to manufacture.

[0138] Further, refer to Figure 3 , Figure 8-Figure 13, the radius of the first base cylinder 20 is R1, the radius of the second base cylinder 210 is R2, and the length of the inner cavity 101 of the shell 1 is L, and the L satisfies: 4R1≥L≥3R1+R2. The length of the inner cavity 101 of the shell 1 refers to the size of the inner cavity 101 of the shell 1 in the direction of the center line connecting the rotating parts 21 of the two sub-pump bodies 2. By making the radius of the first base cylinder 20 of the sub-pump body 2, the radius of the second base cylinder 210 and the length of the inner cavity 101 of the shell 1 satisfy the above relationship, during the rotation of the first sub-pump body 2A and the second sub-pump body 2B, the compartment 22 of one of the first sub-pump body 2A and the second sub-pump body 2B can always be at least partially located in the compartment groove 23 of the other of the first sub-pump body 2A and the second sub-pump body 2B, so that a relatively closed compartment area 113 can be formed, and the size of the compartment area 113 changes with the rotation of the first sub-pump body 2A and the second sub-pump body 2B, thereby achieving liquid suction and liquid pumping.

[0139] In some optional embodiments of the present invention, referring to Figure 3 , Figure 8-Figure 13 The outer peripheral contour surface of the rotating part 21 of one of the first sub-pump body 2A and the second sub-pump body 2B constitutes the inner wall surface of the sub-cell groove 23 as the mating surface 211, and the mating surface 211 of one of the first sub-pump body 2A and the second sub-pump body 2B is suitable for being tangent to the first outer peripheral contour surface 2211 of the other of the first sub-pump body 2A and the second sub-pump body 2B. Therefore, through the tangential contact and cooperation between the mating surface 211 of one of the first sub-pump body 2A and the second sub-pump body 2B and the first outer peripheral contour surface 2211 of the other of the first sub-pump body 2A and the second sub-pump body 2B, the multiple sub-cells 113 can be better separated, avoiding or reducing the lotion 400 in one of the sub-cells 113 from flowing into other sub-cells 113 through the gap between the first sub-pump body 2A and the second sub-pump body 2B, ensuring the accuracy of the amount of lotion delivered in a single time. Moreover, this structure can reduce the friction and wear between the first sub-pump body 2A and the second sub-pump body 2B, and can also make the fit between the first sub-pump body 2A and the second sub-pump body 2B more compact, thereby making the structure of the delivery device 100 compact, which is conducive to the miniaturization of the delivery device 100 and reducing the occupied space.

[0140] In some embodiments of the present invention, reference Figure 3 , Figure 8-Figure 13The grid portion 22 of the first sub-pump body 2A also has a second outer peripheral contour surface 2212 and a third outer peripheral contour surface 2213. The second outer peripheral contour surface 2212 extends in an arc shape from one end of the first outer peripheral contour surface 2211 toward the rotating portion 21 and inward (the "inward" refers to the direction toward the center of the adjacent grid portion 22) and is connected to the rotating portion 21. The third outer peripheral contour surface 2213 extends in an arc shape from the other end of the first outer peripheral contour surface 2211 toward the rotating portion 21 and inward (the "inward" refers to the direction toward the center of the adjacent grid portion 22) and is connected to the rotating portion 21. The first outer peripheral contour surface 2211, the second outer peripheral contour surface 2212 and the third outer peripheral contour surface 2213 surround the grid portion 22. Since the second outer peripheral contour surface 2212 and the third outer peripheral contour surface 2213 of the first sub-pump body 2A both extend inwardly in an arc shape, the second outer peripheral contour surface 2212 and the third outer peripheral contour surface 2213 are formed as arc-shaped surfaces that are recessed toward the center of the adjacent sub-cell 22, the volume of a single sub-cell groove 211 can be increased, and under the condition that the space in the housing 1 is constant, the volume of a single sub-cell area 113 can be increased, thereby increasing the amount of the lotion 400 delivered in a single delivery. In addition, the structure of the sub-cell 22 is simple.

[0141] Similarly, refer to Figure 3 , Figure 8-Figure 13 The grid portion 22 of the second sub-pump body 2B also has a second outer peripheral contour surface 2212 and a third outer peripheral contour surface 2213. The second outer peripheral contour surface 2212 extends in an arc shape from one end of the first outer peripheral contour surface 2211 toward the rotating portion 21 and inward (the "inward" refers to the direction toward the center of the adjacent grid portion 22) and is connected to the rotating portion 21. The third outer peripheral contour surface 2213 extends in an arc shape from the other end of the first outer peripheral contour surface 2211 toward the rotating portion 21 and inward (the "inward" refers to the direction toward the center of the adjacent grid portion 22) and is connected to the rotating portion 21. The first outer peripheral contour surface 2211, the second outer peripheral contour surface 2212 and the third outer peripheral contour surface 2213 surround the grid portion 22. Since the second outer peripheral contour surface 2212 and the third outer peripheral contour surface 2213 of the second sub-pump body 2B both extend inwardly in an arc shape, the second outer peripheral contour surface 2212 and the third outer peripheral contour surface 2213 are formed as arc-shaped surfaces that are recessed toward the center of the adjacent sub-cell 22, the volume of a single sub-cell groove 211 can be increased, and under the condition that the space in the housing 1 is constant, the volume of a single sub-cell area 113 can be increased, thereby increasing the amount of the lotion 400 delivered in a single delivery. In addition, the structure of the sub-cell 22 is simple.

[0142] In some specific embodiments of the present invention, referring to Figure 3 , Figure 8-Figure 13The first sub-pump body 2A includes two compartments 22, which are symmetrically arranged on opposite sides of the rotating part 21. The second outer peripheral contour surfaces 2212 of the two compartments 22 and a part of the outer peripheral surface 212 of the rotating part 21 form the inner wall surface of a compartment groove 23, and the third outer peripheral contour surfaces 2213 of the two compartments 22 and another part of the outer peripheral surface 212 of the rotating part 21 form the inner wall surface of another compartment groove 23, so that the compartment groove 23 is roughly formed into a "3" shape. In this way, the volume of the compartment groove 23 can be made larger, so that the volume of the single compartment area 113 defined between the first sub-pump body 2A and the inner wall of the housing 1 is larger, so that the amount of the lotion 400 delivered in a single time can be increased.

[0143] Similarly, refer to Figure 3 , Figure 8-Figure 13 The second sub-pump body 2B includes two compartments 22, which are symmetrically arranged on opposite sides of the rotating part 21. The second outer peripheral contour surfaces 2212 of the two compartments 22 and a part of the outer peripheral surface 212 of the rotating part 21 form the inner wall surface of a compartment groove 23, and the third outer peripheral contour surfaces 2213 of the two compartments 22 and another part of the outer peripheral surface 212 of the rotating part 21 form the inner wall surface of another compartment groove 23, so that the compartment groove 23 is roughly formed into a "3" shape. In this way, the volume of the compartment groove 23 can be made larger, so that the volume of the single compartment area 113 defined between the second sub-pump body 2B and the inner wall of the housing 1 is larger, so that the amount of the lotion 400 delivered in a single time can be increased.

[0144] According to some optional embodiments of the present invention, the first sub-pump body 2A may include 2-5 sub-grids 22, for example, the first sub-pump body 2A may include 2 sub-grids 22, 3 sub-grids 22, 4 sub-grids 22 or 5 sub-grids 22. By setting the number of sub-grids 22 of the first sub-pump body 2A between 2-5, the accuracy of the amount of lotion dispensed at a single time can be ensured, and the volume of a single sub-grid area 113 can be made appropriate, so as to avoid the volume of a single sub-grid area 113 being too small or too large, resulting in too much or too little amount of lotion 400 dispensed at a single time. In addition, the structure of the first sub-pump body 2A is simple, and it is convenient to process and manufacture.

[0145] According to some optional embodiments of the present invention, referring to Figure 3 , Figure 8-Figure 13 The first sub-pump body 2A and the second sub-pump body 2B have the same shape and size. Thus, the structures of the first sub-pump body 2A and the second sub-pump body 2B can have strong versatility, reduce the types of materials, reduce production costs, and make the mutual cooperation between the first sub-pump body 2A and the second sub-pump body 2B more stable and reliable.

[0146] According to some optional embodiments of the present invention, referring to Figure 3 , Figure 8-Figure 13 , the first sub-pump body 2A and the second sub-pump body 2B are both rotatable, and the rotation directions of the first sub-pump body 2A and the second sub-pump body 2B are opposite. The transmission assembly includes an active member 36 connected to the first sub-pump body 2A and a driven member 37 connected to the second sub-pump body 2B, the active member 36 is meshed with the driven member 37, and the active member 36 is suitable for being driven to drive the first sub-pump body 2A and the second sub-pump body 2B to rotate.
