The spray head body 50 is provided with a plurality of storage cavities 53, the number of the storage cavities 53 is the same as that of the dispensing pumps 10 and corresponds to one another, when the dispensing pump 10 corresponding to each storage cavity 53 works, the dispensing pump 10 corresponding to each storage cavity 53 sucks the lotion 400 in the storage cavity 53 into the dispensing pump 10 through the liquid inlet 111 of the dispensing pump 10, and discharges the lotion through the liquid outlet 112 of the dispensing pump 10. Different types of wash agents 400 may be stored in each storage chamber 53 as needed to meet the user's greater wash needs.

The nozzle body 50 may have one mixing chamber 51 formed therein, or may have a plurality of mixing chambers 51 formed therein. When the spray head body 50 is provided with the mixing cavity 51, during the operation of one of the delivery pumps 10, the liquid outlet 112 of the delivery pump 10 is communicated with the mixing cavity 51, and the liquid outlets 112 of the rest of the delivery pumps 10 are all isolated from the mixing cavity 51, namely, the liquid outlet 112 of the operated delivery pump 10 is communicated with the mixing cavity 51, and the liquid outlet 112 of the non-operated delivery pump 10 is isolated from the mixing cavity 51.

Thus, the movement route of the driving key 31 is simple, the operation control is convenient, and for example, the inclined pressing can be conveniently realized.

In some embodiments of the present invention, referring to fig. 1-6, a delivery device 100 includes: the exterior part 40, the exterior part 40 can be located at the front side of the dispensing pump 10, the front side of the exterior part 40 is provided with an appearance surface 42, the exterior part 40 is provided with a mounting channel 41 for accommodating the driving key 31, the driving key 31 is in sliding fit with the mounting channel 41, the mounting channel 41 can play a role in positioning and guiding the movement of the driving key 31, and the driving key 31 moves in the mounting channel 41 so as to achieve the effect of driving the dispensing pump 10. Wherein the mounting channel 41 extends obliquely downward in the front-to-rear direction, the front end of the mounting channel 41 penetrates through the appearance surface 42, the driving key 31 is adapted to be pressed and moved along the mounting channel 41, and when the driving key 31 is pressed, the driving key 31 is adapted to be moved in the rear and obliquely downward direction in the direction away from the appearance surface 42.

When the dispensing device 100 is used for clothes treating equipment, a user can drive the dispensing pump 10 by pressing the driving key 31 obliquely downwards, and the pressing force can be reduced by means of gravity when the user applies pressure obliquely downwards, so that the dispensing device is more ergonomic, the force application process is more comfortable, and the operation feeling is better. In addition, in the limited installation space of the workbench 600, the driving button 31 moves towards the rear and inclines downwards, the stroke of the driving button 31 in the limited installation space can be increased, and the longer the stroke is, the larger the throwing amount is, so that the driving button 31 moving obliquely realizes the throwing of the lotion 400 with larger dosage. Further, in the driving keys 31 of the same movement stroke, the amount of displacement in the vertical direction of the driving keys 31 moving in the downward direction inclined toward the inside of the exterior member 40 is smaller, and thus, the phenomenon of jamming or the like occurring at the time of operation can be avoided, and the operation experience is improved.

Through moving the driving key 31 towards the backward and downward inclined direction, the amount of the driving key 31 for driving the delivery pump 10 to deliver the lotion 400 once can be increased, the number of times of operation required when the lotion 400 is delivered is reduced, the operation experience of pressing by a user can be considered, the operation force is reduced, the phenomenon of clamping hands and the like during operation is avoided, and the operation experience is improved.

Referring to fig. 1 to 7, in order to facilitate the user operation, the driving key 31 of the dispensing device 100 is disposed forward to satisfy the user's operation habit, specifically, the installation channel 41 extends downward from front to back, that is, the angle between the installation channel 41 and the horizontal direction is greater than 0 ° and less than 90 °, and the user presses the driving key 31, so that the driving key 31 moves backward and downward, thereby realizing the dispensing of the lotion 400 by the dispensing device 100. Accordingly, the driving key 31 is arranged in a downward inclined extending manner from front to back, specifically, the included angle between the driving key 31 and the horizontal direction is larger than 0 degrees and smaller than 90 degrees, so that the operation space of a user is larger, the driving key 31 is convenient to press by the user, the phenomenon that a clamping hand occurs in the process of pressing the driving key 31 is avoided, and the use experience is improved.

In some embodiments of the present invention, referring to fig. 3-6, the cross-sectional area of the installation channel 41 gradually expands in the direction from the appearance surface 42 to the dispensing pump 10, so that in the process of pressing the driving key 31 by a user, the gap between the driving key 31 and the inner wall of the installation channel 41 gradually increases, so that the movement of the driving key 31 in the pressing process becomes smoother, and the operator feel of the driving key 31 is improved.

In some embodiments of the present invention, referring to fig. 1-6, the appearance surface 42 is inclined forward in the top-to-bottom direction, which not only facilitates the user to observe the pattern, mark, etc. on the appearance surface 42, but also enables the user to operate in the space in front of the dispensing device 100, and the appearance surface 42 is arranged to be inclined forward, which makes the distance between the user and the driving key 31 shorter, which is more convenient for operation.

In some embodiments of the present invention, referring to fig. 1-6, the driving key 31 is movable between an initial position and a dispensing position, the driving key 31 is adapted to be moved from the initial position towards a direction away from the appearance surface 42 to the dispensing position under a pressing action, in particular, the driving key 31 is moved obliquely backward and downward from the initial position to the dispensing device 100 under a pressing action, and the dispensing device 100 dispenses the lotion 400 when the driving key 31 is moved to the dispensing position.

Optionally, in the initial position, the pressing surface 312 of the driving key 31 is flush with the appearance surface 42, so that the space occupied by the driving key 31 can be reduced, the appearance of the dispensing device 100 is smoother, and the aesthetic feeling is improved.

Alternatively, in the initial position state, a part of the driving key 31 protrudes from the appearance surface 42, and at this time, the pressing surface 312 of the driving key 31 is located above and in front of the appearance surface 42. The user presses the protruding portion of the driving key 31 to move the driving key 31 along the mounting channel 41, so that the driving key 31 is better in operation feel, and the user can apply force to the driving key 31 more conveniently.

In some alternative embodiments of the present invention, referring to fig. 1-6, a transmission mechanism includes: the driving member 33, the driving member 33 is in driving connection with the driving member 36, the driving member 33 is adapted to be in stop fit with the driving button 31, and when the driving button 31 is pressed, the driving button 31 drives the driving member 33 to move obliquely downwards in the front-to-rear direction. For example, an end of the transmission member 33 near the exterior surface 42 is engaged with the driving key 31, so that the user can simultaneously drive the transmission member 33 to move obliquely downward in the front-to-rear direction when pressing the driving key 31. The transmission member 33 is simultaneously in driving engagement with the dispensing pump 10 such that the dispensing pump 10 can be driven to pump the lotion 400 outwards when the transmission member 33 is moved. By means of the transmission member 33 provided, when the driving button 31 is pressed, a force can be conveniently transmitted to the dispensing pump 10 to drive the dispensing pump 10 to move, thereby dispensing the lotion 400.

In some embodiments of the present invention, referring to fig. 1-6, the side of the driving button 31 near the driving member 33 has a mating groove 311, and the driving member 33 has a mating plate 331 that is in a stop fit with the mating groove 311. The driving key 31 and the transmission piece 33 are in abutting fit with the matching plate 331 through the matching groove 311, so that matching transmission can be completed under the condition that the driving key 31 is separated from the transmission piece 33. The side wall of the matching groove 311 can limit the matching plate 331, so that the stability of the setting of the transmission piece 33 is ensured, and when the driving key 31 is pressed, the inner wall of the matching groove 311 can push the matching plate 331 so that the transmission piece 33 moves along with the movement of the driving key 31.

In some alternative embodiments of the present invention, referring to fig. 1-6, the transmission member 33 may include a drive rack 332, the drive rack 332 may extend obliquely downward in a front-to-rear direction, and the transmission mechanism may further include a drive gear engaged with the drive rack 332, the drive gear being connected to one axial side of the driving member 36. When the driving button 31 is pressed, the driving button 31 drives the transmission member 33 to move backward and obliquely downward, and because the driving button 31 is in stop fit with the transmission member 33, the transmission member 33 can be driven to move backward and obliquely downward, and because the driving rack 332 of the transmission member 33 is meshed with the driving gear arranged on the driving member 36, the driving gear is driven to rotate, and then the driving member 36 and the driven member are driven to rotate, and further the first sub pump body 2A and the second sub pump body 2B can be driven to rotate, the movement of driving the pump body 2 by pressing the driving button 31 can be conveniently realized, and the lotion 400 is put in.

In a further embodiment of the invention, referring to fig. 1-6, the delivery device 100 further comprises: the valve member 60, the dispensing device 100 may include a nozzle body 50, a storage chamber 53, the nozzle body 50 having the above-mentioned mixing chamber 51, and a dispensing hole 52 adapted to communicate with the mixing chamber 51 formed in the nozzle body 50, the valve member 60 being movably disposed at the dispensing hole 52 for opening or closing the dispensing hole 52, for example, the valve member 60 being movably disposed at the dispensing hole 52 up and down to open and close the dispensing hole 52. When the valve member 60 opens the delivery hole 52, the liquid outlet 112 of the delivery pump 10 communicates with the mixing chamber 51 through the delivery hole 52, and when the delivery pump 10 is operated, the lotion 400 pumped from the delivery pump 10 flows into the mixing chamber 51 from the liquid outlet 112 and the delivery hole 52; when the valve member 60 closes the dispensing orifice 52, the liquid outlet 112 of the dispensing pump 10 is blocked from the mixing chamber 51. Opening and closing of the dispensing orifice 52 may be controlled by controlling the movement of the valve member 60 at the dispensing orifice 52. Thus, by controlling the opening and closing of the dispensing hole 52, the dispensing amount of the lotion 400 can be controlled more effectively.

The liquid outlet 112 of the dispensing pump 10 may be located above the dispensing hole 52, so that the lotion 400 dispensed by the dispensing pump 10 can flow downward under the action of gravity and enter the mixing cavity 51 through the dispensing hole 52, thereby avoiding the lotion 400 from being retained in the dispensing pump 10.

In some alternative embodiments of the present invention, referring to fig. 1-6, the driving button 31 can drive the valve component 60 to open the dispensing hole 52 while driving the dispensing pump 10 to work, and the lotion 400 pumped by the dispensing pump 10 can directly enter the mixing cavity 51 through the opened dispensing hole 52, so that the dispensing of the lotion 400 is realized. That is, the valve member 60 and the dispensing pump 10 can be simultaneously driven to work together by one driving button 31, so that the number of driving structures in the dispensing device 100 is reduced, the overall structure of the dispensing device 100 is simpler, the manufacturing cost is reduced, and the dispensing hole 52 is opened by the valve member 60 when the lotion 400 is required to be dispensed due to the simultaneous operation of the valve member 60 and the dispensing pump 10, thereby avoiding the occurrence of liquid leakage of the dispensing device 100 and ensuring that the device is more reliable as a whole. Further, since the valve member 60 and the dispensing pump 10 work together, intermittent dispensing of the treating agent can be realized during the washing process, and leakage of liquid does not occur during the dispensing process, thereby improving the washing effect of the laundry treating apparatus.

In some embodiments of the present invention, the driver 33 has a driving surface 333, the driving surface 333 being slidably engaged with the top of the valve member 60, when the driving button 31 is pressed, the driving button 31 moves backward and obliquely downward, and the driver 33 moves backward and obliquely downward, and the valve member 60 is driven downward by the driving surface 333 of the driver 33 to open the dispensing hole 52. In the state where the driving key 31 is in the initial position, the driving surface 333 is located above the valve component 60 and extends obliquely downward in a direction approaching the valve component 60.

It will be appreciated that in the initial position, the position of the contact point between the driving surface 333 of the driving member 33 and the valve member 60 is highest, and as the driving key 31 moves obliquely downward along the mounting channel 41, the position of the contact point between the driving surface 333 of the driving member 33 and the valve member 60 gradually descends, so that the valve member 60 moves downward under the driving of the driving key 31, and therefore, the driving surface 333 can convert the oblique downward movement trend of the driving member 33 into the downward movement trend of the valve member 60, and push the valve member 60 to move downward, so as to open the dispensing hole 52. Valve member 60 may be reset by a reset member, for example, valve member 60 may be moved upward to a reset position by a reset member.

The process of pressing the drive key 31 to drive the operation of the dispensing pump 10 is described below in connection with fig. 4-6 and fig. 8-13.

Referring to fig. 4, fig. 4 is a schematic view of a portion of the dispensing device 100 in the initial position, in which a portion of the driving button 31 protrudes out of the exterior surface 42, the engaging groove 311 of the driving button 31 is in abutting engagement with the engaging plate 331 of the driving member 33, the driving surface 333 of the driving member 33 is in sliding engagement with the valve member 60, and at the same time, the driving member 33 is in driving engagement with the dispensing pump 10, and the valve member 60 closes the dispensing hole 52.

Referring to fig. 5, in the process of moving the driving key 31 from the initial position toward the rear and obliquely downward, the driving key 31 is adapted to move toward the rear and obliquely downward along the mounting channel 41, and the driving key 31 drives the driving member 33 to move toward the rear and obliquely downward along the mounting channel 41 by the abutting engagement of the engaging groove 311 of the driving key 31 with the engaging plate 331 of the driving member 33. The driving surface 333 of the transmission member 33 is adapted to accompany the obliquely downward movement of the transmission member 33, and since the driving surface 333 is located above the valve part 60 and extends obliquely downward in a direction approaching the valve part 60, the driving surface 333 is adapted to accompany the obliquely downward movement of the transmission member 33 to transmit the downward movement tendency to the valve part 60, so that the valve part 60 moves downward and the dispensing opening 52 is opened. In addition, during the movement of the transmission member 33, the delivery pump 10 is driven so that the delivery pump 10 performs the delivery operation.

Referring to fig. 6, the driving button 31 is further pressed, so that the driving button 31 is pressed to the releasing position, under the action of the abutting fit of the matching groove 311 of the driving button 31 and the matching plate 331 of the driving member 33, the driving member 33 moves to the releasing position at the same time, at this time, the valve member 60 moves to the lowest point under the driving of the driving member 33, the releasing hole 52 is opened, the releasing pump 10 also completes a complete releasing action under the driving of the driving member 33, the releasing pump 10 drives the lotion 400 in the storage cavity 53 to enter the releasing pump 10 through the liquid inlet 111, and is discharged to the mixing cavity 51 through the liquid outlet 112 and the releasing hole 52, and flows into the washing cavity after being mixed with the water flow.

After the lotion 400 is put in, the pressing of the driving key 31 is stopped, the external force applied to the driving key 31 disappears, and at this time, the driving key 31 moves forward and obliquely upward under the action of the elastic reset member 32 and is reset to the initial position. At the same time, the downward force of the driving button 31 to the valve component 60 disappears, the valve component 60 moves upwards to reset to the initial position, and in the process of upwards moving and resetting the valve component 60, the driving member 33 is driven to move forwards and obliquely upwards to reset to the initial position, and the valve component 60 moves upwards until the throwing hole 52 is closed.

A dispensing pump 10 according to an embodiment of the present invention is described below with reference to fig. 1-3 and 8-13.

The dispensing pump 10 includes a housing 1 and a pump body 2, a liquid inlet 111 and a liquid outlet 112 are formed in the housing 1, the pump body 2 is movably arranged in the housing 1, the pump body 2 includes a first sub-pump body 2A and a second sub-pump body 2B arranged along a first direction, and the first sub-pump body 2A and the second sub-pump body 2B are matched with each other. The first sub-pump body 2A and the second sub-pump body 2B define a plurality of mutually separated dividing areas 113 with the inner wall surface of the housing 1, and the lotion is adapted to enter the dividing areas 113 from the liquid inlet 111 and to be discharged from the liquid outlet 112, and the dividing areas 113 are used for temporarily storing the transported lotion 400.

The first sub-pump body 2A and the second sub-pump body 2B are matched with each other, that is, through the mutual matching of the two first sub-pump body 2A and the second sub-pump body 2B, a plurality of mutually separated grid areas 113 are defined between the first sub-pump body 2A and the second sub-pump body 2B and the inner wall surface of the housing 1, and in the moving process of the first sub-pump body 2A and the second sub-pump body 2B, the movement of the first sub-pump body 2A and the second sub-pump body 2B can not interfere with each other through the mutual matching of the first sub-pump body 2A and the second sub-pump body 2B, so that smooth movement of the first sub-pump body 2A and the second sub-pump body 2B is ensured, and no transmission relation exists between the first sub-pump body 2A and the second sub-pump body 2B, that is, one movement of the first sub-pump body 2A and the second sub-pump body 2B does not drive the other movement of the first sub-pump body 2A and the second sub-pump body 2B.

The term "plurality" as used herein means two or more.

The transmission component is connected with the pump body 2 to drive the first sub-pump body 2A and the second sub-pump body 2B to move, through the motion of the first sub-pump body 2A and the second sub-pump body 2B and the mutual cooperation of the first sub-pump body 2A and the second sub-pump body 2B, the lotion 400 can be sucked into the division area 113 in the shell 1 from the liquid inlet 111, and in the process that the first sub-pump body 2A and the second sub-pump body 2B continue to rotate, the first sub-pump body 2A and the second sub-pump body 2B drive the lotion 400 positioned in the division area 113 to flow towards the direction of the liquid outlet 112, and finally can be discharged from the liquid outlet 112.

Specifically, the first sub-pump body 2A and the second sub-pump body 2B are moved by the drive of the transmission assembly. During the movement of the first sub-pump body 2A and the second sub-pump body 2B, the first sub-pump body 2A and the second sub-pump body 2B cooperate with each other, so that a negative pressure can be generated near the liquid inlet 111, and liquid such as the lotion 400 can enter the cell region 113 in the housing 1 through the liquid inlet 111 under the action of the negative pressure and the gravity thereof. Since the first sub-pump body 2A and the second sub-pump body 2B are moved by the driving of the driving assembly, the lotion 400 entering the cell area 113 is moved to the liquid outlet 112 by the pushing of the moved first sub-pump body 2A and second sub-pump body 2B. When the lotion 400 is brought to the liquid outlet 112, the movement and mutual cooperation of the first sub-pump body 2A and the second sub-pump body 2B can squeeze out the liquid in the cell area 113, and finally discharge from the liquid outlet 112.

In this embodiment, the lotion 400 is sucked into the division area 113 from the liquid inlet 111, and the lotion 400 in the division area 113 is brought to the liquid outlet 112 by the movement of the first sub-pump body 2A and the second sub-pump body 2B, in this process, the transmission assembly is used to drive the first sub-pump body 2A and the second sub-pump body 2B to move, so that the lotion in the division area 2 is transferred from the liquid inlet 111 to the liquid outlet 112, and the process that the wash 60 is sucked into the liquid inlet 111 and the wash 60 is discharged out of the liquid outlet 112 is implemented by the movement and the mutual cooperation of the first sub-pump body 2A and the second sub-pump body 2B. Therefore, in this application, drive two sub-pump body motions through setting up drive assembly, the sub-pump body of motion promotes imbibition and flowing back simultaneously, has reduced the dynamics demand of exerting on drive assembly.

The first sub-pump body 2A and the second sub-pump body 2B in this embodiment define a plurality of mutually spaced-apart cell areas 113 with respect to the inner wall surface of the housing 1, and these cell areas 113 are used for temporarily storing the transported lotion 400.

It will be appreciated that when the dispensing device 100 is in the initial state (no wash agent 400 is present in the compartment 113), a negative pressure is generated at the inlet 111 when the pump body 2 is driven by the transmission assembly, and the wash agent 400 is sucked into the compartment 113 in the housing 1 through the inlet 111, and the wash agent 400 is transported to the outlet 112 by the pushing action of the pump body 2, and is discharged from the outlet 112. In this process, the liquid suction at the liquid inlet 111 and the liquid discharge at the liquid outlet 112 are not synchronized in time until the lotion 400 can be discharged at the liquid outlet 112, after which, i.e. when the dispensing device 100 is operating normally, the liquid suction at the liquid inlet 111 and the liquid discharge at the liquid outlet 112 are synchronized in time when the pump body 2 is driven by the transmission assembly to move for dispensing the lotion 400.

And, a plurality of cell areas 113 are defined between the pump body 2 and the inner wall surface of the housing 1, and in the process of dispensing the lotion 400 by the dispensing device 100, the volume of the lotion 400 temporarily contained in a single cell area 113 can be determined by defining the volume of the cell areas 113, and the amount of the lotion 400 dispensed by the user at a time can be the amount of the lotion 400 contained in the single cell area 113, thereby making the amount of the lotion 400 dispensed at a time more accurate.

For example, in some examples of the present invention, reference is made to fig. 8-13 (fig. 9-13 show the process of feeding and discharging liquid from one of the cell areas 113, fig. 9 shows the feeding of liquid from one of the cell areas 113, fig. 10 and 11 show the process of transporting liquid from the cell area 113 in a direction adjacent to the liquid outlet under the driving of the pump body 2, fig. 12 and 13 show the process of discharging liquid, and fig. 13 shows the completion of the dispensing of the lotion from the cell area 113). When the pump body 2 moves to one of the cell areas 113 to communicate with the liquid inlet 111 on the housing 1, the lotion 400 can flow into the cell area 113 through the liquid inlet 111. In the process of continuing to move the pump body 2, the lotion 400 in the grid region 113 is pushed by the pump body 2 towards the liquid outlet 112, and when the pump body 2 moves to the position where the grid region 113 is communicated with the liquid outlet 112, the lotion 400 in the grid region 113 is discharged through the liquid outlet 112, so that the volume of the lotion 400 in a single dispensing is the same as the volume of the single grid region 113, and the accuracy of the lotion 400 in a single dispensing is improved.

According to the dispensing device 100 of the embodiment of the invention, the pump body 2 is provided, a plurality of division areas 113 are defined between the pump body 2 and the inner wall surface of the shell 1, the pump body 2 is provided to comprise two first sub-pump bodies 2A and second sub-pump bodies 2B which are matched with each other, when the dispensing device 100 works normally, the first sub-pump bodies 2A and the second sub-pump bodies 2B are driven to move through the transmission assembly, so that the lotion 400 can be sucked into the division areas 113 from the liquid inlet 111, and the lotion 400 in the division areas 113 is brought to the liquid outlet 112 through the movement of the pump body 2 to be discharged.
