Description

Technical Field

[0001] The present invention relates to the field of detergent dispensing, in particular to a dispensing device, a dispensing component and washing equipment having the same. Background Art

[0002] With the change of consumption habits and consumption upgrades, the usage rate of liquid detergents such as laundry detergent and softener is getting higher and higher. Compared with the trouble of manually adding laundry detergent to the washing machine every time washing clothes and the difficulty in controlling the amount of laundry, washing machines with "automatic dispensing" function are becoming more and more popular. However, the "automatic dispensing" function is expensive and is generally only available on high-end machines. Therefore, a manually driven semi-automatic dispensing device has emerged, which saves users the trouble of carrying a container to pour laundry detergent every time. By setting the amount of dispensing for each manual drive, users can achieve the purpose of accurately dispensing by controlling the number of times the drive device is driven, making users feel more at ease when washing, and can determine the total amount of dispensing according to the cleanliness and material of the laundry. However, the manual dispensing device in the related art is prone to the problem of reverse suction of detergent after manually performing operations such as pressing, making it difficult to ensure the accuracy of detergent dispensing. Summary of the Invention

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

[0007] According to the dispensing device of the embodiment of the present invention, a one-way transmission mechanism is provided. During the process of the driving member moving from the second position to the first position, the driving component drives the one-way transmission mechanism to move, and the one-way transmission mechanism does not drive the pump body to move, thereby helping to avoid the dispensing pump from reversely sucking in the lotion through the liquid outlet, thereby improving the accuracy of lotion dispensing.

The radial length of the active cavity decreases along the first direction. The clutch is movably arranged in the active cavity along the circumference of the one-way transmission wheel. The clutch is elastically connected to the pump body and abuts against the outer peripheral wall of the one-way transmission wheel. When the one-way transmission wheel rotates along the first direction, the one-way transmission wheel drives the clutch to move along the first direction so that the clutch abuts against the radial outer side wall of the active cavity; when the one-way transmission wheel rotates along the second direction, the one-way transmission wheel drives the clutch to move along the second direction so that the clutch is disengaged from the radial outer side wall of the active cavity.

[0052] The following describes embodiments of the present invention in detail, 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 are not to be construed as limiting the present invention.

[0053] The disclosure below provides many different embodiments or examples for realizing different structures of the present invention. In order to simplify the disclosure of the present invention, the components and settings of specific examples are described below. Of course, they are merely examples and are not intended to limit the present invention. In addition, the present invention may repeat reference numbers and / or letters in different examples. This repetition is for the purpose of simplicity and clarity and does not in itself indicate the relationship between the various embodiments and / or settings discussed. In addition, the present invention provides examples of various specific processes and materials, but those skilled in the art will appreciate the applicability of other processes and / or the use of other materials.

[0054] The following describes a dispensing device 10, a dispensing assembly 100 and a washing device 1000 according to an embodiment of the present invention with reference to the accompanying drawings. 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.

[0055] 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 one-way transmission mechanism 3. The detergent may be liquid detergent such as laundry detergent and softener.

[0056] Reference Figure 1 、 Figure 3 and Figure 4 As shown, the dosing pump 1 includes a pump housing 11 and a pump body 12. The pump housing 11 is formed with a liquid inlet 116 and a liquid outlet 117. The drive assembly 2 includes a drive member 21. For example, referring to Figure 1 and Figure 2 As shown, the driving member 21 is arranged on the outside of the pump housing 11. It can be understood that by arranging the driving member 21 on the outside of the pump housing 11, the movement space of the driving member 21 is not limited by the size of the pump housing 11, which is beneficial to increase the movement stroke of the driving member 21, and can increase the single dispensing amount of the dispensing device 10, which is beneficial to reduce the number of dispensing times, and can adapt to the requirements of large-capacity washing equipment such as washing machines and dishwashers for detergent dispensing, which is beneficial to improving the user experience.

[0057] Reference Figure 1 、 Figure 3 and Figure 4 As shown, the driving member 21 is in the first position (refer to Figure 5 ) and the second position (reference Figure 6 ), the one-way transmission mechanism 3 is located between the drive component 2 and the pump body 12, wherein, during the movement of the drive member 21 from the first position to the second position, the drive component 2 drives the one-way transmission mechanism 3 to move, and the one-way transmission mechanism 3 drives the pump body 12 to move, so as to suck the lotion from the liquid inlet 116 and discharge it from the liquid outlet 117, and during the movement of the drive member 21 from the second position to the first position, the drive component 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 drive 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.

[0058] For example, refer to Figure 5 and Figure 6 As shown, the user can manually drive the driving member 21 to move from the first position to the second position, and the one-way transmission mechanism 3 drives the pump body 12 to move, thereby sucking the lotion from the liquid inlet 116 and discharging it from the liquid outlet 117, so as to realize semi-automatic delivery of the delivery device 10, that is, delivering the lotion 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 is disengaged from the pump body 12, and the one-way transmission mechanism 3 does not drive the pump body 12 to move. 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 component 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, 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, and is beneficial to improve the user's operating experience.

[0059] In view of this, according to the dispensing device 10 of an embodiment of the present invention, by providing a one-way transmission mechanism 3, during the process of the driving member 21 moving from the second position to the first position, the driving component 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, thereby helping to avoid the dispensing pump 1 from reversely sucking in the lotion through the liquid outlet 117, and the accuracy of lotion dispensing is high. At the same time, during 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 helpful to reduce the resistance of the driving member 21 moving from the second position to the first position, which is beneficial to improving the user's operating experience.

[0060] In some embodiments of the present invention, reference Figure 4As 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 liquid suction at the liquid inlet 116 and the liquid 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 liquid suction at the liquid inlet 116 and the liquid discharge at the liquid outlet 117 of the dispensing pump 1 are synchronized in time.

[0061] 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 pressing, and the power required for liquid extraction is provided by spring reset, which is similar to the press-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 asking the user to press more times, which will lead to a worse user experience.

[0062] According to the dispensing device 10 of the embodiment of the present invention, 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. The movement stroke of the driving member 21 can be controlled to achieve quantitative control of the amount of detergent dispensed. 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 conducive to increasing the amount of detergent dispensed by the dispensing device 10 in 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 conducive to reducing the number of dispensing times and ensuring the accuracy requirements. It can adapt to the detergent dispensing requirements of large-capacity washing equipment 1000 such as washing machines and dishwashers, and is conducive to improving the user experience.

[0063] Optionally, in some examples, reference Figure 1 and Figure 2 As shown, the pump housing 11 includes a housing portion 111 and an end cover 112. The end cover 112 is detachably arranged at the open end of the housing portion 111. A relatively sealed pump chamber 113 is defined between the housing portion 111 and the end cover 112 (see FIG. Figure 4 ), the pump body 12 is rotatably disposed within the pump compartment 113. It will be appreciated that by detachably disposing the end cap 112 at the open end of the housing portion 111, installation and replacement of the pump body 12 are facilitated. For example, the end cap 112 may be connected to the housing portion 111 by means of a snap connection, a riveted connection, or a threaded fastener connection.

[0064] In some optional embodiments of the present invention, referring to Figure 2 and Figure 5 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 3-Figure 4 As shown, the rotation axis of the driving member 21 is L, and the rotation axis L extends in the left-right direction. It will be understood that the trajectory of the driving member 21 rotating about the rotation axis is an arc. By positioning the first position above the second position, the user can press the driving member 21 to rotate it from the first position to the second position, facilitating the user's application of force to drive the dispensing device 10 to dispense lotion, thereby enhancing the user experience. Of course, the present invention is not limited to this, and the first position may also be positioned below the second position.

[0065] In some optional embodiments of the present invention, referring to Figure 5 and Figure 6 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°. That is to say, 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 can be prevented from being 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 operation of the driving member 21. For example, Figure 5 and Figure 6 As shown, the first position is above the second position. The user presses the free end of the driving member 21 downward to rotate the driving member 21 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.

[0066] 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 2121 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.

[0067] In some optional embodiments of the present invention, referring to Figure 3 and Figure 8 As 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 4 ) or screw (refer to Figure 11 ). Thus, the structure is simple, which is conducive to further improving the reliability of the operation 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 may 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 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 through the liquid outlet 117 to achieve the delivery of the lotion.

[0068] Of course, the present invention is not limited to this. Figure 12 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 drive assembly 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. 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.

[0069] For example, Figure 10As 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 is elastically stopped against the inner circumferential wall of the installation cavity 13. When the driving member 21 moves from the first position to the second position, the driving member 21 drives the one-way transmission mechanism 3 to rotate clockwise. When the one-way transmission mechanism 3 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; when the driving member 21 moves from the second position to the first position, the driving assembly 2 drives the one-way transmission mechanism 3 to move, the one-way transmission mechanism 3 is disengaged from the transmission cooperation with the wheel disc 141, and the one-way transmission mechanism 3 does not drive the pump body 12 to move.

[0070] 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 dosed amount of the dosing pump 1 is not limited by the volume of the dosing pump 1, the single dose of the dosing device 10 can be increased and the dosing accuracy of the single dose 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 circumferential 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 circumferential wall of the installation cavity 13 to achieve closure, which is beneficial to avoid leakage of the dosing device 10.

[0071] In some embodiments of the present invention, reference Figure 12 As shown, the dispensing device 10 further includes a cylindrical mounting seat 15, which is disposed within the pump housing 11 and fixed relative to the pump housing 11. A mounting cavity 13 is formed within the mounting seat 15, and the mounting cavity 13 is eccentrically disposed relative to the mounting seat 15. It will be appreciated that by providing the mounting seat 15 and the pump housing 11 as separate components, the difficulty of machining each of the mounting seat 15 and the pump housing 11 is reduced, thereby reducing mold making costs.

[0072] Of course, the present invention is not limited to this, and the mounting base 15 and the pump housing 11 may also be an integral part. It is understood that the integrally formed structure not only ensures the structural and performance stability of the mounting base 15 and the pump housing 11, but also facilitates molding and simplifies manufacturing. It also eliminates unnecessary assembly parts and connection steps, greatly improving the assembly efficiency of the mounting base 15 and the pump housing 11 and ensuring the reliability of the connection between the mounting base 15 and the pump housing 11. Furthermore, the integrally formed structure has higher overall strength and stability, is more convenient to assemble, and has a longer service life.

[0073] In some embodiments of the present invention, referring to Figure 4As shown, the one-way transmission mechanism 3 is a one-way rotation mechanism, wherein the driving member 21 is moved from the first position (refer to Figure 5 ) moves to the second position (refer to Figure 6 ) process, the one-way transmission mechanism 3 is driven by the driving component 2 along the first direction (refer to Figure 5 When the drive 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, disengaging the one-way transmission mechanism 3 from the pump body 12, and the pump body 12 does not rotate. It can be understood that by engaging or disengaging the one-way transmission mechanism 3 with the pump body 12, whether the driving member 21 drives the pump body 12 can be controlled, resulting in a simple structure and convenient operation.

[0074] For example, refer to Figure 4 As shown, when the dosing pump 1 is working normally, in the process of the driving member 21 rotating from the first position to the second position, 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 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 2 rotating from the second position to the first position, the one-way transmission mechanism 3 rotates clockwise, the one-way transmission mechanism 3 disengages the transmission cooperation with the sub-pump body 121, and the sub-pump body 121 does not rotate, thereby preventing directional suction.

[0075] Of course, the present invention is not limited to this, and can also be achieved by a linearly moving driving member 21 to drive the pump body 12 to rotate. 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 in 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. 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 2 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 disengages from the transmission cooperation with the sub-pump body 121, and the sub-pump body 121 does not rotate, thereby preventing directional suction.

[0076] In some optional embodiments of the present invention, referring to Figure 4As shown. A mating cavity 122 is formed in the pump body 12, and at least a portion of the one-way transmission mechanism 3 is located in the mating cavity 122. In other words, a portion of the one-way transmission mechanism 3 may be located in the mating cavity 122, or the entire one-way transmission mechanism 3 may be located in the mating cavity 122. When the one-way transmission mechanism 3 rotates in a first direction, the one-way transmission mechanism 3 abuts against the inner wall of the mating cavity 122 to drive the pump body 12 to rotate; when the one-way transmission mechanism 3 rotates in a second direction, the one-way transmission mechanism 3 is disengaged from the inner wall of the mating cavity 122. Here, "the one-way transmission mechanism 3 is disengaged from the inner wall of the mating cavity 122" can be understood as the one-way transmission mechanism 3 not transmitting the force that drives the pump body 12 to rotate to the inner wall of the mating cavity 122. For example, the one-way transmission mechanism 3 is separated from the inner wall of the mating cavity 122, or, although the one-way transmission mechanism 3 is in contact with the mating cavity 122, the one-way transmission mechanism 3 cannot drive the pump body 12 to rotate through the inner wall of the mating cavity 122.

[0077] It can be understood that by locating at least part 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.

[0078] In some optional embodiments of the present invention, referring to Figure 4 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 33 located in the matching cavity 122 (refer to Figure 7 ), the one-way transmission wheel 33 includes a transmission shaft 31 and a second matching tooth 32 connected to the transmission shaft 31, 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 can be elastic, or both of the first matching tooth 123 and the second matching tooth 32 can be elastic. Figure 4 When the one-way transmission wheel 33 rotates in the second direction (counterclockwise in the direction of rotation), the second mating teeth 32 and the first mating teeth 123 abut at least in the circumferential direction to drive the pump body 12 to rotate. When the one-way transmission wheel 33 rotates in the second direction, the first mating teeth 123 and the second mating teeth 32 disengage. It will be understood that by configuring at least one of the first mating teeth 123 and the second mating teeth 32 as an elastic member, the first mating teeth 123 and the second mating teeth 32 are disengaged when the one-way transmission wheel 33 rotates in the second direction, thereby facilitating the reliability of the one-way transmission mechanism 3.

[0079] For example, as shown in Reference 4, 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 into 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 33 located in the mating cavity 122. The one-way transmission wheel 33 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 33 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 33 rotates clockwise, the first mating tooth 123 and the second mating tooth 32 disengage.

[0080] In some embodiments of the present invention, reference Figure 7 As shown, the second mating tooth 32 is elastic and 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. The mating section 322 extends circumferentially along the transmission shaft 31 and is spaced apart from the transmission shaft 31. It can be understood that by having the second mating tooth 32 include the connecting section 321 and the mating section 322, when the one-way transmission mechanism 3 rotates in the first direction, the first mating tooth 123 and the mating section 322 abut and engage in the circumferential direction, which helps ensure the reliability of the abutment and engagement between the first mating tooth 123 and the second mating tooth 32. When the one-way transmission mechanism 3 rotates in the second direction, the mating section 322 can deform inwardly to cause the first mating tooth 123 to slip relative to the second mating tooth 32, which helps ensure that the first mating tooth 123 and the second mating tooth 32 are out of transmission engagement, thereby helping to prevent the occurrence of reverse liquid aspiration.

[0081] For example, refer to Figure 4 and Figure 7 As shown, a first mating tooth 123 is formed on the inner wall of the mating cavity 122 of the sub-pump body 121 located at the rear side. The cross section of the first mating tooth 123 is formed into a wedge shape, and the second mating tooth 32 is formed into a pawl. The second mating tooth 32 and the transmission shaft 31 constitute a ratchet. The mating segment 322 is formed into a strip shape and is spaced apart from the transmission shaft 31. The upstream end of the mating segment 322 in the counterclockwise direction is connected to the end of the connecting segment 321 away from the transmission shaft 31. When the driving member 21 is moved from the first position (refer to Figure 5 ) to the second position (refer to Figure 6), the transmission shaft 31 rotates counterclockwise under the drive of the driving component 2, 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 on 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 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 2 rotating from the second position to the first position, the driving component 2 drives the one-way transmission wheel 33 to rotate clockwise, and the first matching tooth 123 abuts against the second matching tooth 32 slips, and the one-way transmission mechanism 3 is disengaged from the transmission cooperation with the sub-pump body 121. 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 matching segment 322 is deformed inward, and the first matching tooth 123 slips relative to the matching segment 322 to disengage the transmission cooperation, which can avoid the reverse suction of liquid by the delivery pump 1, and 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 improving the user's operating experience.

[0082] In some optional embodiments of the present invention, referring to Figure 9 and Figure 10 As shown, the one-way transmission mechanism 3 includes a one-way transmission wheel 33 and a clutch member 34 located in the matching cavity 122. The clutch member 34 is movably arranged between the outer peripheral wall of the one-way transmission wheel 33 and the inner peripheral wall of the matching cavity 122. When the one-way transmission wheel 33 moves in a first direction (refer to Figure 9 When the one-way transmission wheel 33 rotates in the second direction (counterclockwise direction in the middle), the clutch member 34 abuts against the outer peripheral wall of the one-way transmission wheel 33 and the inner peripheral wall of the matching cavity 122; when the one-way transmission wheel 33 rotates along the second direction, the clutch member 34 is disengaged from at least one of the outer peripheral wall of the one-way transmission wheel 33 and the inner peripheral wall of the matching cavity 122. In other words, the clutch member 34 may be disengaged from the outer peripheral wall of the one-way transmission wheel 33 and the inner peripheral wall of the matching cavity 122, or the clutch member 34 may be disengaged from the outer peripheral wall of the one-way transmission wheel 33 and the inner peripheral wall of the matching cavity 122.

[0083] Specifically, when the delivery device 10 is operating normally, the driving member 21 is moved from the first position (refer to Figure 5 ) moves to the second position (refer to Figure 6), the one-way transmission wheel 33 rotates in the first direction under the drive component 2, and the clutch 34 abuts against the outer peripheral wall of the one-way transmission wheel 33 and the inner peripheral wall of the matching cavity 122 of the pump body 12 to drive the pump body 12 to move, which can generate negative pressure in the liquid suction area 114 and positive pressure in the liquid discharge area 115. The lotion at the liquid inlet 116 flows to the liquid discharge port under the action of the pressure difference to realize the delivery of lotion; in the process of the drive component 2 moving from the second position to the first position, the one-way transmission wheel 33 rotates in a second direction opposite to the first direction, and the clutch 34 is disengaged from the transmission cooperation with at least one of the outer peripheral wall of the one-way transmission wheel 33 and the inner peripheral wall of the matching cavity 122, the one-way transmission mechanism 3 is disengaged from the transmission cooperation with the pump body 12, and the pump body 12 does not rotate, which is conducive to preventing the delivery pump 1 from reversely sucking in lotion through the liquid outlet 117, and the accuracy of lotion delivery is high.

[0084] It can be understood that, by making the one-way transmission mechanism 3 include a one-way transmission wheel 33 and a clutch 34, when the one-way transmission mechanism 3 rotates in the first direction, the clutch 34 abuts against the outer peripheral wall of the one-way transmission wheel 33 and the inner peripheral wall of the matching cavity 122, which is conducive to ensuring that the rotational force of the one-way transmission wheel 33 is reliably transmitted to the pump body 12, thereby ensuring the reliability of the rotation of the pump body 12; when the one-way transmission mechanism 3 rotates in the second direction, the clutch 34 is disengaged from the transmission cooperation with at least one of the outer peripheral wall of the one-way transmission wheel 33 and the inner peripheral wall of the matching cavity 122, and the transmission force of the one-way transmission wheel 33 cannot be transmitted to the pump body 12, thereby preventing the pump body 12 from rotating.

[0085] In some embodiments of the present invention, reference Figure 9 As shown, the outer peripheral wall of the one-way transmission wheel 33 and the inner peripheral wall of the matching cavity 122 define an active cavity 35, which is movable along the first direction (refer to Figure 9 The radial length of the active cavity 35 is reduced in the counterclockwise direction of the one-way transmission wheel 33. The clutch 34 is movably arranged in the active cavity 35 along the circumference of the one-way transmission wheel 33. The clutch 34 is elastically connected to the pump body 12 and abuts against the outer peripheral wall of the one-way transmission wheel 33. For example, referring to Figure 9 As shown, the clutch 34 is a movable pin, the clutch 34 is elastically connected to the pump body 12 through the elastic member 36 and abuts against the outer peripheral wall of the one-way transmission wheel 33, wherein the elastic member 36 can be a spring. Figure 9 When the one-way transmission wheel 33 rotates in the counterclockwise direction (in the middle), the one-way transmission wheel 33 drives the clutch member 34 to move in the first direction, so that the clutch member 34 abuts against the radial outer wall of the active cavity 35; when the one-way transmission wheel 33 rotates in the second direction, the one-way transmission wheel 33 drives the clutch member 34 to move in the second direction, so that the clutch member 34 and the radial outer wall of the active cavity 35 are disengaged from the transmission engagement.

[0086] Specifically, when the dispensing device 10 is operating normally, during the process of the driving member 21 moving from the first position to the second position, the one-way transmission wheel 33 rotates in the first direction under the drive of the driving assembly 2, and under the action of the friction between the one-way transmission wheel 33 and the clutch member 34, the one-way transmission wheel 33 drives the clutch member 34 to move in the first direction, and the clutch member 34 abuts against the outer peripheral wall of the one-way transmission wheel 33 and the radial outer side wall of the movable chamber 35 to drive the pump body 12 to move, which can generate negative pressure in the liquid suction area 114 and positive pressure in the liquid discharge area 115. The lotion at the liquid inlet 116 is moved under the action of the pressure difference. The liquid outlet 117 is used to realize the delivery of lotion; in the process of the drive component 2 moving from the second position to the first position, the one-way transmission wheel 33 rotates in a second direction opposite to the first direction, and under the action of the friction between the one-way transmission wheel 33 and the clutch 34, the one-way transmission wheel 33 drives the clutch 34 to move in the second direction, so that the clutch 34 and the radial outer side wall of the movable chamber 35 are disengaged from the transmission cooperation, so that the one-way transmission wheel 33 cannot drive the pump body 12 to rotate, thereby preventing the delivery pump 1 from reversely sucking in lotion through the liquid outlet 117, and the accuracy of lotion delivery is high.

[0087] It can be understood that, by making the clutch member 34 movably provided in the movable cavity 35 along the circumference of the one-way transmission wheel 33, and the clutch member 34 being elastically connected to the pump body 12 and abutting against the outer peripheral wall of the one-way transmission wheel 33, when the one-way transmission mechanism 3 rotates in the first direction, under the action of the friction force between the one-way transmission wheel 33 and the clutch member 34, the one-way transmission wheel 33 drives the clutch member 34 to move in the first direction, and the clutch member 34 abuts against the outer peripheral wall of the one-way transmission wheel 33 and the radial outer side wall of the movable cavity 35. This is beneficial to ensure that the rotational force of the one-way transmission wheel 33 is reliably transmitted to the pump body 12, thereby ensuring the reliability of the rotation of the pump body 12; when the one-way transmission mechanism 3 rotates along the second direction, the one-way transmission wheel 33 rotates along the second direction, and under the action of the friction between the one-way transmission wheel 33 and the clutch member 34, the one-way transmission wheel 33 drives the clutch member 34 to move along the second direction, and the one-way transmission mechanism 3 and the pump body 12 are disengaged from the transmission cooperation, so that the one-way transmission wheel 33 cannot drive the pump body 12 to rotate, thereby ensuring one-way transmission.

[0088] For example, Figure 3 The sub-pump body 121 and the one-way transmission mechanism 3 at the rear side can be replaced by Figure 9The sub-pump body 121, the one-way transmission wheel 33 and the clutch 34, in the process of the driving member 21 rotating from the first position to the second position, the one-way transmission wheel 33 rotates counterclockwise under the drive of the driving assembly 2, and under the action of the friction between the one-way transmission wheel 33 and the clutch 34, the one-way transmission wheel 33 drives the clutch 34 to move in the counterclockwise direction, and the clutch 34 abuts against the outer peripheral wall of the one-way transmission wheel 33 and the radial outer side wall of the movable chamber 35 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 negative pressure in the discharge area. 115 generates positive pressure, 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 one-way transmission wheel 33 rotates in the clockwise direction, and under the action of the friction between the one-way transmission wheel 33 and the clutch member 34, the one-way transmission wheel 33 drives the clutch member 34 to move in the clockwise direction, and the one-way transmission mechanism 3 is disengaged from the pump body 12, so that the one-way transmission wheel 33 cannot drive the pump body 12 to rotate. During this process, the sub-pump body 121 and the other sub-pump body 121 do not rotate, thereby avoiding the reverse suction phenomenon.

[0089] In some optional embodiments of the present invention, referring to Figure 10 As shown, the one-way transmission mechanism 3 includes a retaining frame 37 provided between the outer peripheral wall of the one-way transmission wheel 33 and the inner peripheral wall of the matching cavity 122. The clutch member 34 is swingably provided on the retaining frame 37 along the circumference of the one-way transmission wheel 33 and abuts against the outer peripheral wall of the one-way transmission wheel 33. When the one-way transmission wheel 33 rotates in the first direction, the one-way transmission wheel 33 drives the clutch member 34 toward the first direction (refer to FIG. Figure 10 When the one-way transmission wheel 33 rotates in the second direction, the one-way transmission wheel 33 drives the clutch member 34 to swing in the second direction, so that the clutch member 34 and the inner peripheral wall of the matching cavity 122 are disengaged from the transmission engagement.

[0090] For example, refer to Figure 10 As shown, the clutch member 34 is formed in a non-circular shape. The mating surface between the clutch member 34 and the outer peripheral wall of the one-way transmission wheel 33 has a first arcuate surface 341 and a second arcuate surface 342 connected to each other. The curvature radius of the first arcuate surface 341 is greater than the curvature radius of the second arcuate surface 342. When the one-way transmission wheel 33 rotates in the first direction, the one-way transmission wheel 33 cooperates with the second arcuate surface 342 to drive the clutch member 34 toward the first direction (refer to Figure 10When the one-way transmission wheel 33 rotates in the second direction, the one-way transmission wheel 33 and the first arc-shaped surface 341 drive the clutch member 34 to swing in the second direction, so that the clutch member 34 and the inner peripheral wall of the matching cavity 122 are disengaged from the transmission engagement.

[0091] Specifically, when the dispensing device 10 is operating normally, during the process of the driving member 21 moving from the first position to the second position, the one-way transmission wheel 33 rotates in the first direction under the drive assembly 2, and under the action of the friction between the one-way transmission wheel 33 and the clutch member 34, the one-way transmission wheel 33 drives the clutch member 34 to swing toward the first direction, so that the clutch member 34 stands up (refer to FIG. Figure 10 ) is supported between the one-way transmission wheel 33 and the matching cavity 122, so that the one-way transmission wheel 33 can drive the clutch 34 and the pump body 12 to rotate synchronously, and negative pressure can be generated in the liquid suction area 114 and positive pressure can be generated in the liquid discharge area 115. The lotion at the liquid inlet 116 flows to the liquid outlet 117 under the action of the pressure difference to achieve the delivery of the lotion; in the process of the drive component 2 moving from the second position to the first position, the one-way transmission wheel 33 rotates in a second direction opposite to the first direction. Under the action of the friction force between the one-way transmission wheel 33 and the clutch 34, the one-way transmission wheel 33 drives the clutch 34 to swing in the second direction, so that the clutch 34 tilts (refer to Figure 13 ), the clutch 34 is disengaged from the inner circumferential wall of the matching cavity 122, and the one-way transmission wheel 33 cannot drive the pump body 12 to rotate, which is beneficial to prevent the delivery pump 1 from reversely sucking in the lotion through the liquid outlet 117, and the accuracy of lotion delivery is high.

[0092] It can be understood that, by making the clutch member 34 swingably provided on the retaining frame 37 along the circumference of the one-way transmission wheel 33 and abutting against the outer peripheral wall of the one-way transmission wheel 33, when the one-way transmission mechanism 3 rotates in the first direction, under the action of the friction force between the one-way transmission wheel 33 and the clutch member 34, the one-way transmission wheel 33 drives the clutch member 34 to swing in the first direction, so that the clutch member 34 stands up to be supported between the one-way transmission wheel 33 and the matching cavity 122, so that the one-way transmission wheel 33 can drive the clutch member 34 and the pump body 12 to rotate synchronously, which is beneficial In order to ensure that the rotational force of the one-way transmission wheel 33 is reliably transmitted to the pump body 12, thereby ensuring the reliability of the rotation of the pump body 12; when the one-way transmission mechanism 3 rotates along the second direction, the one-way transmission wheel 33 rotates along the second direction, and under the action of the friction between the one-way transmission wheel 33 and the clutch member 34, the one-way transmission wheel 33 drives the clutch member 34 to swing along the second direction, so that the clutch member 34 tilts to disengage the transmission cooperation with the inner circumferential wall of the matching cavity 122, and the one-way transmission wheel 33 cannot drive the pump body 12 to rotate, and the one-way transmission mechanism 3 has high working reliability.

[0093] For example, Figure 3The sub-pump body 121 and the one-way transmission mechanism 3 at the rear side can be replaced by Figure 10 The sub-pump body 121, the one-way transmission wheel 33, the clutch 34 and the retaining frame 37 in the process of the driving member 21 rotating from the first position to the second position, the one-way transmission wheel 33 rotates counterclockwise under the drive of the driving assembly 2, and under the action of the friction between the one-way transmission wheel 33 and the clutch 34, the one-way transmission wheel 33 drives the clutch 34 to swing in the counterclockwise direction, so that the clutch 34 stands up to be supported between the one-way transmission wheel 33 and the matching cavity 122, so that the one-way transmission wheel 33 can drive the clutch 34 and the sub-pump body 121 to rotate synchronously, and the sub-pump body 121 drives the other sub-pump body 121 to rotate, thereby in the liquid suction area 11 4 generates negative pressure, and positive pressure is generated in the discharge area 115. The lotion at the liquid inlet 116 flows to the liquid outlet 117 under the action of the pressure difference; when the driving member 21 rotates from the second position to the first position, the one-way transmission wheel 33 rotates in the clockwise direction. Under the action of the friction between the one-way transmission wheel 33 and the clutch member 34, the one-way transmission wheel 33 drives the clutch member 34 to swing in the clockwise direction. The clutch member 34 tilts and disengages from the inner peripheral wall of the matching cavity 122, so that the clutch cannot drive the pump body 12 to rotate. During this process, the sub-pump body 121 and the other sub-pump body 121 do not rotate, thereby avoiding the reverse liquid suction phenomenon.

[0094] In some optional embodiments of the present invention, referring to Figure 5 and Figure 6 As shown, the dispensing device 10 includes a first transmission mechanism 23 that is transmission-connected to the driving member 21. The first transmission mechanism 23 is located outside the mating cavity 122 and is connected to the one-way transmission wheel 33. It is understood that by properly setting the transmission ratio between the first transmission mechanism 23 and the driving member 21, the rotation angle of the pump body 12 can be controlled, thereby facilitating increasing the single dispensing amount of the dispensing device 10 and reducing the number of dispensing times.

[0095] In some examples, the first transmission mechanism 23 and the one-way transmission wheel 33 are integrally formed. It is understood that the integrally formed structure not only ensures the structural and performance stability of the first transmission mechanism 23 and the one-way transmission wheel 33, but also facilitates molding and simplifies manufacturing. It also eliminates unnecessary assembly parts and connection steps, greatly improving the assembly efficiency of the first transmission mechanism 23 and the one-way transmission wheel 33 and ensuring the reliability of the connection between the first transmission mechanism 23 and the one-way transmission wheel 33. Furthermore, the integrally formed structure has higher overall strength and stability, is more convenient to assemble, and has a longer service life.

[0096] In some optional embodiments of the present invention, referring to Figure 5As shown, the first transmission mechanism 23 is a gear. For example, the first transmission mechanism 23 can be coaxially arranged with the corresponding sub-pump body 121. This has a simple structure and is conducive to ensuring the reliability of the operation of the first transmission mechanism 23.

[0097] In some optional embodiments of the present invention, referring to Figure 5 As shown, the drive assembly 2 includes a second transmission mechanism 24 connected to the drive member 21, and the second transmission mechanism 24 meshes with the first transmission mechanism 23. The drive member 21 is rotatably connected to the pump housing 11 between a first position and a second position. The second transmission mechanism 24 is an arcuate rack and extends circumferentially along the rotation axis of the drive member 21. It can be understood that the provision of the first transmission mechanism 23 and the second transmission mechanism 24 facilitates ensuring a reliable transmission connection between the drive member 21 and the one-way transmission mechanism 3. By reasonably setting the transmission ratio between the second transmission mechanism 24 and the first transmission mechanism 23, the rotation angle of the pump body 12 can be controlled, which helps increase the single delivery volume of the delivery device 10 and reduce the number of deliveries. At the same time, since the rotation trajectory of the drive member 21 is an arc, the provision of the second transmission mechanism 24 as an arcuate rack helps improve the reliability of the cooperation between the first transmission mechanism 23 and the second transmission mechanism 24, thereby extending the service life.

[0098] For example, refer to Figure 6 As shown, the first transmission mechanism 23 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 second transmission mechanism 24 drives the first transmission mechanism 23 to rotate counterclockwise. The first transmission mechanism 23 drives the one-way transmission mechanism 3 to rotate counterclockwise to drive the sub-pump body 121 located on the rear side 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 liquid inlet 116 to the liquid outlet 117.

[0099] In some embodiments of the present invention, reference Figure 2 and Figure 5 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, and the pressing portion 211 is connected to the end of the connecting portion 212 away from the pump housing 11; the second transmission mechanism 24 is connected to the pressing portion 211, and the first transmission mechanism 23 is located in the accommodating cavity 25 defined by the second transmission mechanism 24 and the connecting portion 212. It can be understood that by locating the second transmission mechanism 24 in the accommodating cavity 25 defined by the first transmission mechanism and the connecting portion 212, it is helpful to reduce the entry of foreign matter into the matching position of the first transmission mechanism 23 and the second transmission mechanism 24, thereby ensuring the reliability of the matching between the second transmission mechanism 24 and the first transmission mechanism 23. For example, referring to Figure 6 As shown, the accommodating cavity 25 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 this application, reference is made to Figure 5 As shown, the pressing portion 211 and the connecting portion 212 are an integral part. It can be understood that the integrally formed structure not only ensures the structural and performance stability of the pressing portion 211 and the connecting portion 212, but also facilitates molding and simple manufacturing, and eliminates 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] Of course, the present invention is not limited to this. In other examples, the driving member 21 may also be movable. In other words, the moving trajectory of the driving member 21 is a straight line. For example, the driving member 21 is movably provided on the pump housing 11, and the driving member 21 is movable between a third position and a fourth position, wherein the third position is located above the fourth position, the first transmission mechanism 23 is a gear and is connected to the pump body 12 through the one-way transmission mechanism 3, and the second transmission mechanism 24 is provided on the driving member 21 and is a rack extending along the moving direction of the driving member 21. When the dispensing device 10 is working normally, in the process of the driving member 21 moving from the third position to the fourth position, the second transmission mechanism 24 drives the first transmission mechanism 23 to rotate, and the one-way transmission mechanism 3 drives the pump body 12 to move to drive the liquid from the liquid inlet 116 to the liquid outlet 117; in the process of the driving member 21 moving from the fourth position to the third position, the second transmission mechanism 24 drives the first transmission mechanism 23 to rotate, the one-way transmission mechanism 3 is disengaged from the transmission cooperation with the pump body 12, and the one-way transmission mechanism 3 does not drive the pump body 12 to move.

[0102] In some optional embodiments of the present invention, referring to Figure 5 As shown, the drive assembly 2 also includes an elastic return member 22. The drive member 21 moves from the first position to the second position under the action of an external force applied by the user, and after the external force applied by the user is removed, the elastic return member 22 is used to drive the drive member 21 to return from the second position to the first position. Therefore, after the drive member 21 is moved from the first position to the second position, it is not necessary to manually return the drive member 21 to the first position, which further facilitates user operation. In addition, compared with traditional manual delivery devices, since the suction area 114 and the discharge area 115 of the delivery pump 1 are located in different areas, when the delivery device 10 is working normally, the suction at the liquid inlet 116 and the discharge at the liquid outlet 117 of the delivery pump 1 are synchronized in time, so there is no need for the elastic return member 22 to have a large return force. The user does not need to use much force when pressing the drive assembly 2 to achieve delivery, which is conducive to improving the user's operating comfort.

[0103] Of course, the present invention is not limited to this. The driving component 2 may also not include the elastic reset member 22. After the user drives the driving member 21 to move from the first position to the second position, the driving member 21 may also be manually operated to reset the driving member 21 from the second position to the first position.

[0104] In some embodiments of the present invention, reference Figure 5 As shown, one end of the elastic reset member 22 is connected to the driving member 21 and the other end is connected to the pump housing 11. Figure 5 As shown, the elastic return member 22 is a spring, one end of the elastic return member 22 is connected to the upper portion 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 5 As shown, when the driving member 215 is subjected to the driving force F, the elastic reset member 22 is deformed by tension (refer to Figure 6 ), when the driving force F is withdrawn, the elastic reset member 22 recovers its deformation to drive the driving member 21 to reset, which has a simple structure and is easy to operate.

[0105] Reference Figure 1 and Figure 2 As shown, the delivery assembly 100 according to an embodiment of the present invention comprises: a delivery device 10 and a storage box 20 for storing lotion, wherein the delivery device 10 is the delivery device 10 according to the above embodiment of the present invention, and the storage box 20 defines a storage cavity 201, which is communicated with the liquid inlet 116. For example, referring to Figure 8 As shown, the storage box 20 is located above the dispensing device 10 , so that the lotion in the storage box 20 can flow toward the liquid inlet 116 under the action of gravity.

[0106] According to the dispensing component 100 of the embodiment of the present invention, by setting the dispensing device 10 according to the above-mentioned embodiment of the present invention, in the process of the driving member 21 moving from the second position to the first position, the driving component 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, thereby helping to avoid the dispensing pump 1 from reversely sucking in the lotion through the liquid outlet 117, and helping to ensure the accuracy of the lotion dispensing. 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 helpful to reduce the resistance of the driving member 21 moving from the second position to the first position, and help to improve the user's operating experience.

[0107] In some embodiments of the present invention, reference Figure 1 and Figure 2As shown, the storage box 20 is provided 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 helps to reduce the space occupied by the storage box 20 and the pump housing 11 as a whole, and helps to achieve a miniaturized dispensing assembly 100. Alternatively, in other embodiments, the storage box 20 and the pump housing 11 are connected by a connecting pipe. This facilitates the connection, and the storage box 20 and the pump housing 11 can be arranged separately, which can increase the flexibility of the installation of the dispensing assembly 100.

[0108] In some embodiments of the present invention, reference Figure 1 and Figure 2 As shown, the storage box 20 is provided on the pump housing 11, and the storage box 20 is detachably connected to the pump housing 11. It is understandable that the detachable connection between the storage box 20 and the pump housing 11 facilitates replacement or maintenance of the storage box 20 and the pump housing 11, which helps reduce maintenance costs.

[0109] 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 mounted on the open end of the integral member formed by the housing portion 111 and the storage box 20 via a threaded fastener. It is understood that the integrally formed structure not only ensures the structural and performance stability of the housing portion 111 and the storage box 20, but also facilitates molding and is simple to manufacture. It also eliminates 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 ease of assembly. The threaded fastener can achieve a tight connection between the end cap 112 and the integral member formed by the housing portion 111 and the storage box 20. In addition, while ensuring the connection strength of the integral member formed by the end cap 112, the housing portion 111 and the storage box 20, it can also reduce costs. Optionally, the threaded fastener can be a screw, a bolt, or a stud.

[0110] Alternatively, in other embodiments, the storage box 20 is integrally formed with the pump housing 11. It is understood that the integrally formed structure not only ensures the structural and performance stability of the storage box 20 and the pump housing 11, but also facilitates molding and simplifies manufacturing. It also eliminates unnecessary assembly parts and connection steps, greatly improving the assembly efficiency of the storage box 20 and the pump housing 11 and ensuring the reliability of the connection between the storage box 20 and the pump housing 11. Furthermore, the integrally formed structure has higher overall strength and stability, is more convenient to assemble, and has a longer service life.

[0111] Reference Figure 8As shown, a washing device 1000 according to an embodiment of the present invention comprises: a dispensing component 100 according to the above embodiment of the present invention. The washing device 1000 may be a washing machine, a dishwasher, a sink or the like.

[0112] For example, Figure 8 As shown, washing device 1000 is specifically a washing machine. Washing device 1000 includes a dispensing assembly 100, a water inlet valve 200, a mixing chamber 300, and a washing tub 400. Dispensing assembly 100 is located above and communicates with mixing chamber 300. Water inlet valve 200 is connected to mixing chamber 300 to control the supply of water to mixing chamber 300. Washing tub 400 is located below the outlet of mixing chamber 300. Detergent and water are mixed in mixing chamber 300 and then flow to washing tub 400 for washing clothes. It will be appreciated that when water flows through detergent in mixing chamber 300, it can achieve the purpose of dilution and mixing, which is more conducive to washing. Of course, the present invention is not limited to this. Dispensing assembly 100 can also directly dispense detergent into washing tub 400.

[0113] According to the washing device 1000 of the embodiment of the present invention, by setting the dispensing component 100 according to the above-mentioned embodiment of the present invention, in the process of the driving member 21 moving from the second position to the first position, the driving component 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, thereby helping to avoid the dispensing pump 1 from reversely sucking in the detergent through the liquid outlet 117, and helping to ensure the accuracy of the detergent dispensing. 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 helpful to reduce the resistance of the driving member 21 moving from the second position to the first position, which is helpful to improve the user's operating experience and improve the overall performance of the washing device 1000.

[0114] The specific structures of the dispensing device 10, the dispensing assembly 100 and the washing device 1000 of the present invention are described in detail below with reference to the accompanying drawings. Of course, it is understood that the following description is intended to explain the present invention and cannot be used as a limitation of the present invention.

[0115] Refer to the attached Figure 1-8 As shown, according to an embodiment of the present invention, a washing device 1000 is specifically a washing machine. The washing device 1000 includes a dispensing component 100, a water inlet valve 200, a mixing chamber 300 and a washing tank 400.

[0116] Reference Figure 8As shown, the dispensing assembly 100 is located above and communicates with the mixing chamber 300. The water inlet valve 200 is connected to the mixing chamber 300 to control whether water is supplied to the mixing chamber 300. The washing tub 400 is located below the outlet of the mixing chamber 300. The detergent and water can be mixed in the mixing chamber 300 and then flow into the washing tub 400 for washing clothes. It can be understood that when the water flows through the detergent in the mixing chamber 300, it can achieve the purpose of dilution and mixing, which is more conducive to washing.

[0117] 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. The storage box 20 is in communication with the dispensing device 10 to provide lotion to the dispensing device 10 .

[0118] Reference Figure 3-Figure 5 As shown, the dispensing device 10 includes a dispensing pump 1, a one-way transmission mechanism 3 and a drive assembly 2. The dispensing pump 1 includes a pump casing 11 and a pump body 12. Optionally, 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, and the end cover 112 is detachably provided at the open end of the integral piece of the casing portion 111 and the storage box 20 by a threaded fastener.

[0119] Reference Figure 5 As shown, the pump body 12 is located in the pump casing 11 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. The two sub-pump bodies 121 form a liquid suction area 114 and a liquid discharge area 115 arranged in the up-down direction in the pump casing 11. A liquid inlet 116 corresponding to the liquid suction area 114 and a liquid outlet 117 corresponding to the liquid discharge area 115 are formed on the pump casing 11. The liquid inlet 116 is connected to the storage box 20, and the liquid outlet 117 is connected to the top of the mixing chamber 300. Specifically, the liquid inlet 116 is located above the meshing portion of the two sub-pump bodies 121, and the liquid outlet 117 is located below the meshing portion of the two sub-pump bodies 121.

[0120] Specifically, 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 into a wedge shape, and the one-way transmission mechanism 3 includes a one-way transmission wheel 33 located in the mating cavity 122, the one-way transmission wheel 33 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 along the circumference of the transmission shaft 31 and is spaced apart from the transmission shaft 31.

[0121] Reference Figure 1-Figure 3 As shown, the drive assembly 2 is located on the left side of the dosing pump 1. The drive assembly 2 includes a drive member 21, a first transmission mechanism 23, a second transmission mechanism 24 and an elastic reset member 22. The drive member 21 is rotatably connected to the pump housing 11 between a first position and a second position. The drive 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.

[0122] Reference Figure 4 and Figure 5 As shown, the first transmission mechanism 23 is located outside the mating cavity 122 and is fixedly connected to the transmission shaft 31. The first transmission mechanism 23 is a gear. The second transmission mechanism 24 is connected to the pressing portion 211. The second transmission mechanism 24 is an arc-shaped rack and extends circumferentially along the rotation axis of the driving member 21. The second transmission mechanism 24 and the connecting portion 212 define an accommodating cavity 25. The first transmission mechanism 23 is located in the accommodating cavity 25 and is meshed with the second transmission mechanism 24. The elastic return member 22 is a spring. The elastic return member 22 is located above the driving member 21 and is connected between the pressing portion 211 and the pump housing 11.

[0123] Reference Figure 6 As shown, in the process of the driving member 21 moving from the first position to the second position, the second driving mechanism drives the first driving mechanism to rotate, the first driving mechanism drives the one-way transmission wheel 33 to rotate, the one-way transmission wheel 33 drives the sub-pump body 121 located on the rear side to rotate, 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; in the process of the driving member 21 moving from the second position to the first position, the second transmission mechanism 24 drives the first transmission mechanism 23 to rotate, the first transmission mechanism 23 drives the one-way transmission wheel 33 to rotate, and the one-way transmission wheel 33 does not drive the sub-pump body 121 located on the rear side to rotate.

[0124] Specifically, when the delivery device 10 is working normally, refer to Figure 4 As shown, when the driving force F presses the driving member 21 so that the driving member 21 rotates from the first position to the second position, specifically the driving member 21 rotates counterclockwise around the rotation axis L, and the rotation trajectory of the driving member 21 is an arc. During this process, the second transmission mechanism 24 drives the first transmission mechanism 23 to rotate counterclockwise, and the first transmission mechanism 23 drives the one-way transmission wheel 33 connected to the first transmission mechanism 23 to rotate counterclockwise, and the one-way transmission wheel 33 drives the corresponding sub-pump body 121 to rotate. The sub-pump body 121 engages with another sub-pump body 121 to drive 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. The lotion at the liquid inlet 116 flows to the discharge area 115 under the action of the pressure difference and is discharged through the liquid outlet 117 to realize the delivery of the lotion. At the same time, the elastic reset member 22 is pulled during this process.

[0125] 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 is working 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 user's operation comfort. At the same time, the transmission ratio of the first transmission mechanism 23 and the second transmission mechanism 24 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. Moreover, on the basis of a certain volume of the delivery device 10, the single delivery amount of the delivery device 10 of the embodiment of the present invention is large, which is conducive to reducing the number of times the user operates the delivery, and is conducive to further improving the user experience.

[0126] When the user's driving force is withdrawn, under the action of the elastic return member 22, the driving member 21 automatically returns to the first position clockwise from the second position. During this process, the second transmission mechanism 24 drives the first transmission mechanism 23 to rotate clockwise, and the first transmission mechanism 23 drives the one-way transmission wheel 33 to rotate clockwise so that the mating section 322 is deformed inward, and the mating section 322 slips with the first mating tooth 123 so that the mating section 322 does not transmit power to the corresponding sub-pump body 121, so that the one-way transmission mechanism 3 has the effect of one-way transmission, which can avoid the phenomenon of reverse suction of the delivery pump 1. At the same time, 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 can effectively reduce the restoring force of the elastic return member 22, which is beneficial to shorten the reset time, thereby improving the user's operating experience.
