In some alternative embodiments of the invention, illustrated with reference to fig. 6-7, the axis of rotation of the driver 21 extends substantially horizontally, the first position being above the second position. For example, as shown in fig. 6 to 7, the rotational axis of the driver 21 is L, which extends in the left-right direction. It can be understood that the track that driving piece 21 rotates around rotation axis L is the pitch arc, and through making the first position be located the top of second position, the user can press driving piece 21 so that driving piece 21 rotates to the second position by first position, and the user application of force in order to drive and put in device 10 and put in lotion is convenient for, is favorable to improving user's use experience. Of course, the present invention is not limited thereto, and the first position may be located below the second position.

In some alternative embodiments of the invention, as illustrated with reference to fig. 6 and 7, the angle between the first position and the second position is no greater than 120 °. In other words, the angle between the line connecting the first position and the center of rotation of the driver 21 and the line connecting the second position and the center of rotation of the driver 21 is not more than 120 °. That is, the rotational angle of the driving member 21 from the first position to the second position or the rotational angle from the second position to the first position is not more than 120 °. Therefore, the included angle between the first position and the second position is not too large, which is beneficial to avoiding the overlarge rotation stroke of the driving part 21 on the one hand, and is beneficial to avoiding the interference of the driving part 21 with other parts on the other hand, thereby being beneficial to ensuring the working reliability of the driving part 21. For example, as shown in fig. 7, the first position is located above the second position, and the user presses the free end of the driving member 21 downward to rotate the driving member 21 from the first position to the second position in the counterclockwise direction around the rotation axis L, in which process the rotation track of the driving member 21 is an arc.

The rotation angle of the driving member 21 from the first position to the second position may be 10 °, 20 °, 30 °, 40 °, 50 °, 60 °, 70 °, 80 °, 90 °, 100 °, 110 °, or 120 °, and the design of the rotation angle of the driving member 21 from the first position to the second position may be adjusted according to actual needs, which is not limited in the present invention.

In some alternative embodiments of the present invention, referring to fig. 6 and 7, the valve 4 is connected to the driving member 21, and during the movement of the driving member 21 from the second position to the first position, the driving member 21 can move the valve 4 to close the liquid outlet 117. It will be appreciated that the valve 4 is connected to the driving member 21, so that the driving member 21 drives the valve 4 to open or close the liquid outlet 117.

It can be understood that, referring to fig. 6 and 7, when the driving member 21 receives the driving force F, the first elastic resetting member 22 is deformed in tension, and when the driving force F is removed, the first elastic resetting member 22 is deformed again to drive the driving member 21 to reset, so that the structure is simple and the operation is convenient.

In some alternative embodiments of the present invention, the valve 4 is movably disposed at the liquid outlet 117, the valve 4 is not connected to the driving member 21, and during the process of moving the driving member 21 from the first position to the second position, the driving member 21 pushes the valve 4 to move to open the liquid outlet 117. Therefore, the structure is simple, and the operation is convenient; as another example, referring to fig. 9, the valve 4 is movably disposed at the liquid outlet 117, and during the process that the driving member 21 moves from the first position to the second position, the driving member 21 pushes the valve 4 to move to open the liquid outlet 117. For example, in one example, the valve 4 is rotatably disposed at the liquid outlet 117, and during the process that the driving member 21 rotates from the first position to the second position, the driving member 21 pushes the valve 4 to rotate to open the liquid outlet 117.

For example, referring to fig. 9, the valve 4 is movably disposed in the pump housing 11 in the front-rear direction, the pump housing 11 includes a housing main body 1111, a liquid draining portion 1112 and a stopping portion 118, the housing main body 1111 defines a pump chamber 113 (see fig. 5) therein, the liquid draining portion 1112 has a flow passage 1113 communicating with the pump chamber 113, one side of the liquid draining portion 1112 is opened to define the liquid outlet 117, the stopping portion 118 is spaced from the liquid draining portion 1112, one end of the pushing portion 214 is connected to the connecting portion 212 of the driving member 21, the other end of the pushing portion 214 is formed with a first step 213, the valve 4 includes a main body portion 41 and a sealing portion 42 connected to each other, the upper end of the main body portion 41 is formed with a second step 43, the first step 213 is engaged with the second step 43 to push the valve 4 to move, the sealing portion 42 is protruded from one side of the main body portion 41 adjacent to the liquid outlet 117, the second elastic restoring member 5 is connected between the main body portion 41 and the stopping portion 118 to normally push the valve 4 to move the valve 4 in a direction of closing the liquid outlet 117, the pump housing 11 is further provided with a guiding structure 6, the guiding structure 6 extends in an axial direction of the second elastic restoring member 5, and the guiding structure 6 is engaged with the valve 4 to move in the axial direction of the second elastic restoring member 5.

In some embodiments of the present invention, and as illustrated with reference to FIG. 5, the pump body 12 is rotatably disposed within the pump housing 11 such that a suction region 114 and a discharge region 115 are formed within the pump housing 11, with the intake port 116 corresponding to the suction region 114 and the discharge port 117 corresponding to the discharge region 115. For example, when the dispensing device 10 is in the initial state (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, so as to generate a negative pressure in the liquid-suction area 114, and a positive pressure in the discharge area 115, and the lotion at the liquid inlet 116 flows to the discharge area 115 under the action of the pressure difference, during which 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 at the liquid outlet 117, and thereafter, i.e. when the dispensing device 10 is operating 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.

It should be noted that, in practical research, the inventor finds that the principle of the manual dispensing device in the related art is to use a reciprocating device, similar to a plunger pump, for changing the volume ratio of the cavity of the pumping and discharging device to achieve liquid suction and liquid discharge, where the liquid suction and liquid discharge are alternately performed, in other words, the liquid suction and liquid discharge of the manual dispensing device in the related art are located in the same area and are asynchronous in time, the liquid discharge force is provided by manual pressing, the power required for liquid suction is provided by spring return, and the manual dispensing device is similar to a pressing and dispensing device for shampoo or liquid in daily life.

According to the dispensing device 10 of the embodiment of the invention, the movement stroke of the driving member 21 is related to the rotation angle of the pump body 12, quantitative control of the dispensing amount of the lotion can be realized by controlling the movement stroke of the driving member 21, and because the liquid suction area 114 and the liquid discharge area 115 of the dispensing pump 1 are located in different areas, when the dispensing device 10 works normally, liquid suction at the liquid inlet 116 and liquid discharge at the liquid outlet 117 of the dispensing pump 1 are synchronized in time, so that the dispensing amount of the dispensing pump 1 is not limited by the volume of the dispensing pump 1, which is beneficial to increasing the dosage of the single dispensing of the dispensing device 10, and further, 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 precision of the single dispensing can be ensured, which is beneficial to reducing the dispensing times and ensuring the precision requirements, which can meet the requirements of washing equipment 1000 with large capacity such as washing machines and dishwashers, and the like, and is beneficial to improving the use experience of users.

Therefore, the structure is simple, the reliability of the work of the pump body 12 is further improved, and the feeding precision of single feeding is guaranteed. Of course, the present invention is not limited to this, the pump body 12 may also be replaced by two gear pump bodies that can rotate and mesh with each other, for example, the pump body 12 may include an internal gear and an external gear, the external gear is located inside the internal gear and is eccentrically disposed with respect to the internal gear, the driving part 21 of the driving assembly 2 is connected to the external gear, the external gear drives the external gear to rotate by the rotation of the driving part 21, the external gear drives the internal gear to rotate, thereby driving the lotion in the pump housing 11 to flow, so as to generate a negative pressure at the liquid inlet 116, and generate a positive pressure at the liquid outlet 117, and the lotion in the liquid suction region 114 flows to the liquid discharge region 115 and sequentially flows through the flow passage 1113 and is discharged through the liquid outlet 117 under the effect of the pressure difference, so as to implement the dispensing of the lotion.

For example, as shown in fig. 11, one end of each vane 142 is connected to the disc 141 through a spring element 143, so that the other end of each vane 142 elastically abuts against the inner peripheral wall of the mounting cavity 13, when the driving assembly 2 drives the vane pump 14 to rotate clockwise, the vane 142 rotates the liquid in the mounting cavity 13, and due to the eccentric arrangement of the disc 141, a negative pressure is generated at the liquid inlet 116 to achieve a liquid suction effect, and a positive pressure is generated at the liquid outlet 117 to cause the liquid to be squeezed out at the liquid outlet 117 to achieve a liquid discharge effect.

It can be understood that the control of the dosage of the lotion can be realized by controlling the rotation angle of the driving member 21, and the liquid suction and the liquid discharge of the dosage pump 1 are synchronous in time, so that the dosage of the dosage pump 1 is not limited by the volume of the dosage pump 1, the dosage of the dosage device 10 can be increased and the dosage precision of the dosage of the single dosage can be ensured, meanwhile, because one end of each blade 142 is connected with the wheel disc 141 and the other end is elastically abutted against the inner peripheral wall of the installation cavity 13, the reliable liquid feeding and liquid discharge of the dosage pump 1 can be ensured, and when the impeller pump 14 stops working, the other end of each blade 142 is elastically abutted against the inner peripheral wall of the installation cavity 13 to realize the sealing, which is beneficial to avoiding the leakage of the dosage device 10.

It can be understood that, the integrated into one piece's structure not only can guarantee mount pad 15 and pump case 11 structure, the stability of performance to convenient shaping, make simply, and saved unnecessary assembly part and connection process moreover, improved the assembly efficiency of mount pad 15 and pump case 11 greatly, guarantee the reliability that mount pad 15 and pump case 11 are connected, moreover, the bulk strength and the stability of the structure of integrative formation are higher, it is more convenient to assemble, the life-span is longer.

In some embodiments of the invention, as illustrated with reference to fig. 6, the drive assembly 2 comprises a transmission 23, the transmission 23 being connected between the drive member 21 and the pump body 12. Therefore, the single throwing amount of the throwing device 10 can be increased and the throwing times can be reduced by reasonably setting the transmission ratio among the driving piece 21, the transmission mechanism 23 and the pump body 12.

In some embodiments of the present invention, referring to fig. 6, the transmission mechanism 23 includes a first transmission member 231 and a second transmission member 232 engaged with each other, the first transmission member 231 is connected to the driving member 21, and the second transmission member 232 is connected to the pump body 12. It can be understood that, by making the transmission mechanism 23 include the first transmission member 231 and the second transmission member 232 engaged with each other, the reliability of the operation of the transmission mechanism 23 is improved, and the structure is simple and the operation is convenient. For example, referring to fig. 6 and 7, the second transmission member 232 can be connected to the sub-pump body 121 at the rear side, when the driving member 21 rotates counterclockwise from the first position to the second position, the first transmission member 231 drives the second transmission member 232 to rotate counterclockwise, the second transmission member 232 drives the sub-pump body 121 to rotate counterclockwise, the sub-pump body 121 drives the sub-pump body 121 at the front side to rotate, so as to drive the liquid to flow from the liquid-absorbing region 114 to the liquid-discharging region 115 and to the liquid outlet 117 through the flow passage 1113, and the driving member 21 drives the valve 4 to open the liquid outlet 117 to dispense the lotion.

In some embodiments of the present invention, referring to fig. 6, the pump body 12 is driven to move by the rotation of the driving member 21, the first transmission member 231 is an arc-shaped rack and extends along the circumferential direction of the rotation axis of the driving member 21, and the second transmission member 232 is a gear. For example, the second transmission member 232 is a gear and is located outside the dispensing pump 1, and a portion of the pump body 12 is connected to the second transmission member 232 through the pump housing 11. It can be understood that, since the rotation track of the driving member 21 is an arc, by making the first transmission member 231 an arc-shaped rack, it is beneficial to improve the reliability of the cooperation between the first transmission member 231 and the second transmission member 232, and prolong the service life.

In some embodiments of the present invention, referring to fig. 6, the driving member 21 includes a pressing portion 211 and a connecting portion 212, the connecting portion 212 is rotatably connected to the pump casing 11, the pressing portion 211 is connected to an end of the connecting portion 212 far from the pump casing 11, the first transmission member 231 is connected to the pressing portion 211, and the second transmission member 232 is located in the accommodating cavity 24 defined by the first transmission member 231 and the connecting portion 212. It can be understood that, by positioning the second transmission member 232 in the accommodating cavity 24 defined by the first transmission member 231 and the connecting portion 212, it is beneficial to reduce the entrance of foreign objects into the matching position between the first transmission member 231 and the second transmission member 232, and the reliability of the matching between the second transmission member 232 and the first transmission member 231 is ensured. For example, referring to FIG. 6, the receiving cavity 24 forms an arc-shaped cavity, the center of which coincides with the center of rotation of the driver 21.

Optionally, in some examples of the present application, referring to fig. 6, the pressing portion 211 and the connecting portion 212 are an integral piece, it can be understood that the integrally formed structure not only can ensure the structural stability and performance stability of the pressing portion 211 and the connecting portion 212, but also is convenient to form and simple to manufacture, and unnecessary assembly parts and connecting processes are omitted, so that the assembly efficiency of the pressing portion 211 and the connecting portion 212 is greatly improved, and the reliability of the connection of the pressing portion 211 and the connecting portion 212 is ensured.

In some embodiments of the present invention, as shown in fig. 5, the dispensing device 10 further includes a one-way transmission mechanism 3, the driving member 21 is movable between a first position and a second position, the one-way transmission mechanism 3 is located between the driving assembly 2 and the pump body 12, wherein during the movement of the driving member 21 from the first position to the second position, the driving member 21 drives the valve 4 to move so as to open the liquid outlet 117, and simultaneously drives the one-way transmission mechanism 3 to move, 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 the lotion from the liquid outlet 117, during the movement of the driving member 21 from the second position to the first position, the driving assembly 2 drives the one-way transmission mechanism 3 to move, the one-way transmission mechanism 3 does not drive the pump body 12 to move, in other words, during the movement of the driving member 21 from the second position to the first position, the one-way transmission mechanism 3 is disengaged from the pump body 12, and when the driving member 21 returns to the first position, the valve 4 closes the liquid outlet 117.

For example, referring to fig. 6 and 7, a user can move from a first position to a second position by manually driving the driving member 21, the driving member 21 drives the valve 4 to move to open the liquid outlet 117, 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 the lotion from the liquid outlet 117, so as to realize semi-automatic dispensing of the dispensing device 10, that is, manually dispensing the lotion, 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, the one-way transmission mechanism 3 is disengaged from the pump body 12, the one-way transmission mechanism 3 does not drive the pump body 12 to move, and when the driving member 21 returns to the first position, the valve 4 closes the liquid outlet 117.

It can be understood that, by providing the unidirectional transmission mechanism 3, in the process that the driving member 21 moves from the second position to the first position, the driving member 21 drives the unidirectional transmission mechanism 3 to move, and the unidirectional transmission mechanism 3 does not drive the pump body 12 to move, thereby being beneficial to avoiding that the dispensing pump 1 reversely sucks the lotion through the liquid outlet 117, and being beneficial to ensuring the dispensing accuracy of the lotion, meanwhile, in the process that the driving member 21 moves from the second position to the first position, because the unidirectional transmission mechanism 3 does not drive the pump body 12 to move, the resistance of the driving member 21 moving from the second position to the first position is beneficial to reducing, which is beneficial to improving the operation experience of a user, and when the driving member 21 returns to the first position, the valve 4 closes the liquid outlet 117, which can effectively prevent the problems of drying and solidification of the residual liquid, oxidation, and the like, and can also reduce the sealing requirement of the pump body 12 in the dispensing device 10, and is beneficial to simplifying the structure of the dispensing device 10, thereby reducing the manufacturing difficulty, saving the cost, and at the same time, without additionally increasing the operation difficulty of the user.

In some embodiments of the present invention, referring to fig. 6, the one-way transmission mechanism 3 is a one-way rotation mechanism, wherein, during the process that the driving member 21 moves from the first position (refer to fig. 6) to the second position (refer to fig. 7), the driving member 21 drives the valve 4 to move so as to open the liquid outlet 117, and meanwhile, the one-way transmission mechanism 3 is driven by the driving assembly 2 to rotate along the first direction (refer to the counterclockwise direction in fig. 5), and the one-way transmission mechanism 3 cooperates with the pump body 12 to drive the pump body 12 to move; in the process that the driving assembly 2 moves from the second position to the first position, the one-way transmission mechanism 3 rotates along a second direction opposite to the first direction, the one-way transmission mechanism 3 is disengaged from the pump body 12 in a transmission way, and the pump body 12 does not rotate. It can be understood that the one-way transmission mechanism 3 is matched with or separated from the pump body 12, so that whether the driving piece 21 drives the pump body 12 to move or not can be controlled, the structure is simple, and the operation is convenient.

For example, referring to fig. 4 and 5, when the dispensing pump 1 works normally, in the process that the driving member 21 rotates from the first position to the second position, the driving member 21 drives the valve 4 to move to open the liquid outlet 117, and simultaneously, the one-way transmission mechanism 3 rotates counterclockwise under the driving of the driving assembly 2, the one-way transmission mechanism 3 cooperates with one of the sub-pump bodies 121 to drive the sub-pump body 121 to rotate, the sub-pump body 121 drives the other sub-pump body 121 to rotate, so that a negative pressure is generated in the liquid suction region 114, a positive pressure is generated in the liquid discharge region 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 that the driving assembly 2 rotates from the second position to the first position, the one-way transmission mechanism 3 rotates clockwise, the one-way transmission mechanism 3 is disengaged from the sub-pump body 121, the sub-pump body 121 does not rotate, so that directional liquid suction can be prevented, and when the driving member 21 returns to the first position, the valve 4 closes the liquid outlet 117.

Of course, the present invention is not limited to this, and it can also be that the driving member 21 is moved to drive the pump body 12 to rotate, specifically, in the process that the driving member 21 moves from the first position to the second position, the one-way transmission mechanism 3 is driven by the driving assembly 2 to rotate along the first direction, the one-way transmission mechanism 3 cooperates with one of the sub-pump bodies 121 to drive the sub-pump body 121 to rotate, the sub-pump body 121 drives the other sub-pump body 121 to rotate, so as to generate a negative pressure in the liquid suction area 114, generate a positive pressure in the liquid discharge area 115, and the lotion at the liquid inlet 116 flows to the liquid outlet 117 under the action of the pressure difference; during the process of moving the driving assembly 22 from the second position to the first position, the one-way transmission mechanism 3 rotates in the second direction opposite to the first direction, the one-way transmission mechanism 3 is disengaged from the sub-pump body 121, and the sub-pump body 121 does not rotate, so that reverse liquid suction can be prevented.

In some alternative embodiments of the present invention, reference is made to FIG. 4. A matching cavity 122 is formed in the pump body 12, at least a part of the one-way transmission mechanism 3 is located in the matching cavity 122, in other words, a part of the one-way transmission mechanism 3 may be located in the matching cavity 122, or the entire one-way transmission mechanism 3 is located in the matching cavity 122, and when the one-way transmission mechanism 3 rotates along the first direction, the one-way transmission mechanism 3 abuts against the inner wall of the matching cavity 122 to drive the pump body 12 to rotate; when the unidirectional transmission mechanism 3 rotates along the second direction, the unidirectional transmission mechanism 3 is disengaged from the inner wall of the engagement cavity 122 in a transmission manner. Here, "the one-way transmission mechanism 3 is disengaged from the inner wall of the fitting cavity 122" may be understood as that the one-way transmission mechanism 3 does not transmit the acting force for driving the pump body 12 to rotate to the inner wall of the fitting cavity 122, for example, the one-way transmission mechanism 3 is separated from the inner wall of the fitting cavity 122, or, although the one-way transmission mechanism 3 is in contact with the fitting cavity 122, the one-way transmission mechanism 33 cannot drive the pump body 12 to rotate through the inner wall of the fitting cavity 122.

It can be understood that, by locating at least part of the unidirectional transmission mechanism 3 in the matching cavity 122, the space occupation of the pump body 12 and the unidirectional transmission mechanism 3 on the whole can be reduced, and meanwhile, the unidirectional transmission mechanism 3 is abutted against or separated from the inner wall of the matching cavity 122, which is beneficial to ensuring the reliability of the unidirectional transmission mechanism 3.

In some alternative embodiments of the present invention, as shown in fig. 5, the inner wall of the engagement cavity 122 is formed with a first engagement tooth 123, the unidirectional transmission mechanism 3 includes a unidirectional transmission wheel 3a located in the engagement cavity 122, the unidirectional transmission wheel 3a includes a transmission shaft 31 and a second engagement tooth 32 connected to the transmission shaft 31, at least one of the first engagement tooth 123 and the second engagement tooth 32 is elastic, in other words, one of the first engagement tooth 123 and the second engagement tooth 32 is elastic, or both of the first engagement tooth 123 and the second engagement tooth 32 are elastic, and when the unidirectional transmission wheel 3a rotates in a counterclockwise direction in fig. 4 in a first direction, the second engagement tooth 32 and the first engagement tooth 123 abut at least in a circumferential direction to drive the pump body 12 to rotate; when the one-way transmission wheel 3a rotates in the second direction, the first engagement tooth 123 and the second engagement tooth 32 are disengaged. It can be understood that, by making at least one of the first engaging tooth 123 and the second engaging tooth 32 be an elastic member, it is advantageous to ensure that the first engaging tooth 123 and the second engaging tooth 32 are in a disengaged state when the one-way transmission wheel 3a rotates in the second direction, thereby being advantageous to ensure the reliability of the operation of the one-way transmission mechanism 3.

For example, referring to fig. 5, a plurality of first engaging teeth 123 are formed on an inner wall of the engaging cavity 122 of the sub-pump body 121 located on the rear side, each first engaging tooth 123 is formed in a wedge shape in cross section, the plurality of first engaging teeth 123 are uniformly spaced on an inner peripheral wall of the engaging cavity 122, the unidirectional transmission mechanism 3 includes a unidirectional transmission wheel 3a located in the engaging cavity 122, the unidirectional transmission wheel 3a includes a transmission shaft 31 and a second engaging tooth 32 connected to the transmission shaft 31, the first engaging teeth 123 are rigid members, the second engaging tooth 32 has elasticity, and when the unidirectional transmission wheel 3a rotates counterclockwise, the second engaging tooth 32 and the first engaging tooth 123 abut in a circumferential direction to drive the pump body 12 to rotate; when the one-way transmission wheel 3a33 rotates in the clockwise direction, the first engaging tooth 123 and the second engaging tooth 32 are disengaged.

In some embodiments of the present invention, referring to fig. 5, the second mating tooth 32 has elasticity, 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 an end of the connecting section 321 away from the transmission shaft 31, and the mating section 322 extends in a circumferential direction of the transmission shaft 31 and is spaced apart from the transmission shaft 31. It can be understood that, by making the second matching tooth 32 include the connecting section 321 and the matching section 322, when the unidirectional transmission mechanism 3 rotates along the first direction (referring to the counterclockwise direction in fig. 5), the first matching tooth 123 and the matching section 322 are in butt-joint engagement in the circumferential direction, which is beneficial to ensuring the reliability of the butt-joint engagement between the first matching tooth 123 and the second matching tooth 32, when the unidirectional transmission mechanism 3 rotates along the second direction, the matching section 322 can be inwardly deformed so that the first matching tooth 123 slips relative to the second matching tooth 32, which is beneficial to ensuring that the first matching tooth 123 and the second matching tooth 32 are out of the transmission engagement, thereby being beneficial to preventing the occurrence of the phenomenon of reverse liquid suction.

In some examples, second transmission member 232 and one-way transmission wheel 3a are integrally formed.
