Detailed Description

Reference will now be made in detail to embodiments of the present invention, examples of which are illustrated in the accompanying drawings, wherein like or similar reference numerals refer to the same or similar elements or elements having the same or similar function throughout. The embodiments described below with reference to the accompanying drawings are illustrative only for the purpose of explaining the present invention, and are not to be construed as limiting the present invention.

A delivery device 10 according to an embodiment of the present invention is described below with reference to fig. 1-13. The putting device 10 can be used in washing equipment with a water inlet system, such as a washing machine, a dishwasher, a wash platform or a sink, and the like, the putting device 10 is used for putting a washing agent 60, and the washing agent can be liquid washing agents 60, such as laundry detergent, softener and the like.

The dispensing device 10 according to an embodiment of the first aspect of the invention comprises: liquid inlet 111 and liquid outlet 112, casing 1, box subassembly and drive assembly. Lotion 60 can enter the interior cavity 101 of the housing 1 from the inlet port 111 and exit from the outlet port 112. A cell assembly is movably arranged in the inner cavity 101 of the housing 1, the cell assembly comprising two cell parts 2, the two cell parts 2 being arranged in cooperation with each other. A plurality of spaced-apart cell areas 113 are defined between the two cell pieces 2 and the inner wall surface of the housing 1, and the cell areas 113 are used for temporarily storing the transported lotion 60.

Wherein, two division check spare 2 are mutually supported and set up means through the mutually supporting of two division check spare 2 for a plurality of cellular regions 113 of mutual spaced apart are injectd between two division check spare 2 and the internal wall face of casing 1, and in the in-process of two division check spare 2 movements, through the mutually supporting of two division check spare 2, can make the motion of two division check spare 2 not take place to interfere, guarantee the smooth motion of two division check spare 2, and do not have the transmission relation between two division check spare 2, one of them division check spare 2's motion can not drive another division check spare 2 motion promptly.

In the present invention, "a plurality" means two or more.

The transmission assembly is connected with the grid assembly to drive the two grid parts 2 to move, through the movement of the two grid parts 2 and the mutual matching of the two grid parts 2, the lotion 60 can be sucked into the grid areas 113 in the shell 1 from the liquid inlet 111, and in the process that the two grid parts 2 continue to rotate, the two grid parts 2 drive the lotion 60 in the grid areas 113 to flow towards the liquid outlet 112, and finally can be discharged from the liquid outlet 112.

In particular, two cell elements 2 within the cell assembly move under the drive of the drive assembly. During the movement of the two compartments 2, the two compartments 2 cooperate with one another and can generate an underpressure in the vicinity of the inlet opening 111, under the influence of which underpressure and of their own weight liquid, such as lotion 60, can enter the compartment areas 113 in the housing 1 through the inlet opening 111. Since the partitions 2 are driven by the transmission assembly to move, the lotion 60 entering the partitions 113 moves to the liquid outlet 112 under the push of the moving partitions 2. When the lotion 60 is brought to the outlet 112, the movement of the two compartments 2, in cooperation with each other, can squeeze the liquid out of the compartment 113 and eventually out of the outlet 112.

In this application, the motion of dividing grid 2 is driven by drive assembly, transmits the lotion in dividing grid 2 from inlet 111 to liquid outlet 112, and two cooperation motions of dividing grid 2 can realize sucking washing 60 into inlet 111 and will washing 60 discharge outlet 112. Consequently, in this application, drive the transmission that two branch check spare movements realized the washing through drive assembly, the motion of two branch check spares can promote imbibition and flowing back simultaneously, consequently, the design of this application has reduced the dynamics demand at the in-process that liquid was put in.

It will be appreciated that when the dispensing device 10 is in the initial state (no lotion 60 is present in the cell area 113), when the transmission assembly drives the cell assembly to move, a negative pressure can be generated at the liquid inlet 111, and the lotion 60 flows into the cell area 113 in the housing 1 through the liquid inlet 111, and is transported to the liquid outlet 112 by the pushing action of the cell assembly and is discharged from the liquid outlet 112. In the 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 liquid outlet 112 can discharge the lotion 60, and thereafter, when the dispensing device 10 is in normal operation, the liquid suction at the liquid inlet 111 and the liquid discharge at the liquid outlet 112 are synchronized in time when the transmission assembly drives the grid assembly to move to dispense the lotion 60.

And, at the same time, a plurality of cell areas 113 are defined between the cell assembly and the inner wall surface of the casing 1, and during the process of dispensing the lotion 60 by the dispensing device 10, the volume of the lotion 60 temporarily contained in a single cell area 113 can be determined by defining the volume of the cell area 113, and the amount of the lotion 60 dispensed by a user at a time can be the amount of the lotion 60 contained in a single cell area 113, so that the amount of the lotion 60 dispensed at a time is more accurate.

For example, in some examples of the present invention, referring to fig. 8-12 (fig. 8-12 show the processes of feeding liquid into one of the cell areas 113 and discharging liquid, in which fig. 8 shows the process of feeding liquid into one of the cell areas 113, fig. 9 and 10 show the process of moving the liquid in the cell area 113 toward the direction adjacent to the liquid outlet under the driving of the cell member 2, that is, the process of transporting liquid, and fig. 10 and 11 show the process of discharging liquid, and fig. 11 shows the process of discharging liquid in the cell area 113, the cell assembly is movably disposed in the housing 1, and the cell assembly and the inner wall surface of the housing 1 jointly define a plurality of cell areas 113 spaced from each other. When the cell assembly is moved to a position where one of the cell areas 113 is in communication with the inlet 111 of the housing 1, the lotion 60 can flow into the cell area 113 through the inlet 111. In the process of continuously moving the grid assembly, the lotion 60 in the grid area 113 is pushed by the grid assembly towards the liquid outlet 112, and when the grid assembly moves to a position where the grid area 113 is communicated with the liquid outlet 112, the lotion 60 in the grid area 113 is discharged through the liquid outlet 112, so that the amount of the lotion 60 which is thrown at one time is the same as the volume of the single grid area 113, and the accuracy of the lotion 60 which is thrown at one time is improved.

The transmission assembly can move under the action of external force applied by a user, namely, when the user applies the external force to the transmission assembly, the transmission assembly moves. The user can manually actuate the movement of the transmission assembly to actuate the movement of the tab assembly to achieve semi-automatic dispensing of the dispensing device 10, i.e., manually dispense a metered amount of the lotion 60. It can be understood that the movement of the transmission assembly is realized by the action of the external force applied by the user, so that it is no longer necessary to provide another power source for driving the transmission assembly in the dispensing device 10, and therefore, the space of the dispensing device 10 can be saved, the miniaturization of the dispensing device 10 can be facilitated, and the manufacturing cost of the dispensing device 10 can be reduced. Specifically, when a user needs to dispense the lotion 60, an acting force can be applied to the transmission assembly, so that the transmission assembly moves under the action of the external force applied by the user, and the grid assembly is driven to move, and then the lotion 60 is dispensed.

Alternatively, the transmission assembly may be driven by other power sources to move, and the specific source of the external force applied to the transmission assembly is not limited in the present invention.

According to the dispensing device 10 of the embodiment of the invention, the grid assembly is arranged, a plurality of grid sections 113 are defined between the grid assembly and the inner wall surface of the shell 1, the grid assembly is arranged to comprise two grid pieces 2 which are matched with each other, when the dispensing device 10 works normally, the two grid pieces 2 are driven to move through the transmission assembly, the lotion 60 can be sucked into the grid sections 113 from the liquid inlet 111, and the lotion 60 in the grid sections 113 is brought to the liquid outlet 112 to be discharged through the movement of the grid pieces 2. In the existing pump structure, such as a gear pump, the gear of the pump needs to realize both the transmission function and the liquid conveying function, and the transmission function prevents the backlash from being too large, otherwise, the transmission effect is affected; the invention sets the separate grid-dividing piece 2 for liquid transmission, and the transmission of the grid-dividing piece is realized by the transmission component, therefore, the grid-dividing area 113 can be set to be larger, and the effect of improving the single transfusion quantity is realized.

According to some embodiments of the invention, referring to fig. 7-12, the volume of an individual cell 113 may be varied during movement of the cell assembly. For example, during the movement of the cell assembly, when one of the cell areas 113 is in communication with the inlet 111, the volume of the cell area 113 may be changed by the movement of the two cell members 2 and the cooperation thereof during the short period of time that the cell area 113 is in communication with the inlet 111, so that the volume of the cell area 113 is gradually increased, which may generate a negative pressure in the cell area 113 (as shown in fig. 8), thereby allowing the lotion 60 to flow from the inlet 111 into the cell area 113.

During continued movement of the tab assembly, the tab region 113 is no longer in communication with the inlet port 111 and the lotion 60 is no longer entering the tab region 113, such that the amount of lotion 60 contained within the tab region 113 remains constant and the volume of the tab region 113 may remain constant as the tab assembly moves into communication with the outlet port 112. In the process that the lotion 60 in the cell area 113 moves towards the direction adjacent to the liquid outlet 112 under the driving of the cell component, when the cell area 113 is communicated with the liquid outlet 112, the volume of the cell area 113 can be changed through the movement and the mutual cooperation of the two cell pieces 2 in the short time that the cell area 113 is communicated with the liquid outlet 112, so that the volume of the cell area 113 is gradually reduced, positive pressure can be generated in the cell area 113 (as shown in fig. 11), the lotion 60 in the cell area 113 is squeezed by the cell component, and the lotion 60 can be discharged from the liquid outlet 112.

During the movement of the cell assembly, the volume of the single cell 113 can be changed, so that the negative pressure can be conveniently formed near the liquid inlet 111 and the positive pressure can be conveniently formed near the liquid outlet 112, and the lotion 60 can be more smoothly sucked and discharged.

According to some embodiments of the present invention, the inlet port 111 may be disposed higher than the outlet port 112. It will be appreciated that the liquid inlet 111 is disposed higher than the liquid outlet 112 so that the lotion 60 can be more easily dispensed through the liquid outlet 112 under the influence of gravity. Of course, the present invention is not limited thereto, and in another example of the present invention, the liquid inlet 111 may be as high as the liquid outlet 112.

According to some embodiments of the present invention, referring to fig. 2 to 4 and fig. 7, the cell area 113 extends along a direction perpendicular to the arrangement direction of the two cell members 2, for example, the two cell members 2 may be arranged in the left-right direction, and the cell area 113 may extend in the up-down direction. By enabling the extending direction of the cell dividing area 113 to be perpendicular to the arrangement direction of the two cell dividing pieces 2, the extending space of the cell dividing area 113 can be ensured not to influence the movement space of the transmission assembly, so that the space utilization rate inside the throwing device 10 is optimized, and the structure is more compact.

According to some embodiments of the present invention, referring to fig. 2 to 13, two cells 2 in the cell assembly may rotate, and the rotation directions of the two cells 2 are opposite, and a plurality of cell sections 113 may be defined between the outer peripheral profile surfaces of the two cells 2 and the inner wall surface of the housing 1. By rotatably arranging the two division pieces 2, the movement of the division pieces 2 is simple and easy to realize, and the rotation directions of the two division pieces 2 are opposite, so that the generation of negative pressure near the liquid inlet 111 and the generation of positive pressure near the liquid outlet 112 can be conveniently realized, and the suction and the discharge of the lotion 60 can be conveniently realized.

According to some embodiments of the present invention, referring to fig. 5-7, two compartments 2 are rotatable, two compartments 2 are a first compartment 2A and a second compartment 2B, respectively, and each of the first compartment 2A and the second compartment 2B includes: the rotating part 21 and the plurality of cell parts 22, the plurality of cell parts 22 may be arranged at intervals along the circumferential direction of the rotating part 21, a cell groove 23 may be defined between two adjacent cell parts 22, and an inner wall surface of the cell groove 23 may form a part of an inner wall surface of the cell area 113. By providing the cells 2 in the above-described structure, the cells 113 having a large volume can be defined between the cells 2 and the inner wall surface of the housing 1, so that the amount of lotion delivered per one time can be increased.

In some alternative embodiments of the invention, with reference to fig. 5-7, each cell 2 comprises: the rotating part 21 and the multiple cell parts 22, the multiple cell parts 22 can be arranged at intervals along the circumferential direction of the rotating part 21, and the cell parts 22 extend along the axial direction of the rotating part 21, so that the cell grooves 23 defined between the two cell parts 22 extend along the axial direction of the cell part 2, the volume of the cell grooves 23 can be increased, and further the cell areas 113 extending along the axial direction of the cell part 2 can be defined between the peripheral outline of the cell part 2 and the inner wall of the shell 1, and the volume of the cell areas 113 can be effectively increased.

For example, two cell members 2 are arranged in the left-right direction, the rotating portion 21 of each cell member 2 extends in the up-down direction, and the cell portion 22 of each cell member 2 extends in the up-down direction, so that a cell region 113 extending in the up-down direction of the cell member 2 is defined between the outer peripheral outline of the cell member 2 and the inner wall of the housing 1. In the related art, if the amount of lotion to be dispensed at a single time is to be increased, the volume of the dispensing device needs to be changed, and the driving force for the dispensing device to suck the lotion is increased as the volume of the dispensing device is increased. In the present application, in order to increase the amount of the washing agent to be applied in a single dose, as shown in fig. 5, the channel of the channel partition 113, which is configured as a channel partition 113 extending up and down, can be made long. The larger the channels of the cells 113, the more lotion can be contained and the more lotion can be dispensed in a single dose.

According to some alternative embodiments of the present invention, referring to fig. 5-7, the two compartments 2 are a first compartment 2A and a second compartment 2B, respectively, and each of the first compartment 2A and the second compartment 2B comprises: the rotating portion 21 and the plurality of cell portions 22, the plurality of cell portions 22 may be connected to the outer circumferential surface 212 of the rotating portion 21, the plurality of cell portions 22 may be arranged at intervals in the circumferential direction of the rotating portion 21, for example, the plurality of cell portions 22 may be arranged at even intervals in the circumferential direction of the rotating portion 21. Each adjacent two of the cell portions 22 of the first cell piece 2A and the second cell piece 2B may define a cell recess 23 therebetween, at least a part of the cell portion 22 of the first cell piece 2A being adapted to be received in the cell recess 23 of the second cell piece 2B, and/or at least a part of the cell portion 22 of the second cell piece 2B being adapted to be received in the cell recess 23 of the first cell piece 2A. It may be that at least a part of the cell portion 22 of the first cell piece 2A is adapted to be accommodated in the cell groove 23 of the second cell piece 2B, it may be that at least a part of the cell portion 22 of the second cell piece 2B is adapted to be accommodated in the cell groove 23 of the first cell piece 2A, it may be that at least a part of the cell portion 22 of the first cell piece 2A is adapted to be accommodated in the cell groove 23 of the second cell piece 2B and at least a part of the cell portion 22 of the second cell piece 2B is adapted to be accommodated in the cell groove 23 of the first cell piece 2A.

Referring to fig. 8 to 12, during the rotation of the first and

second lattice pieces

2A and 2B, a part of the stages may be that at least a part of the cell part 22 of the first lattice piece 2A is adapted to be received in the cell groove 23 of the second lattice piece 2B, and another part of the stages may be that at least a part of the cell part 22 of the second lattice piece 2B is adapted to be received in the cell groove 23 of the first lattice piece 2A. In the process of rotating the two cell pieces 2, at least a part of one cell part 22 of the first cell piece 2A may be accommodated in one cell groove 23 of the second cell piece 2B, or at least a part of one cell part 22 of the second cell piece 2B may be accommodated in one cell groove 23 of the first cell piece 2A, so that the two cell pieces 2 are matched and avoided in the process of moving, and a relatively closed cell area can be formed while avoiding interference. In the process that the first lattice piece 2A and the second lattice piece 2B rotate, the lattice groove 23 of one of the first lattice piece 2A and the second lattice piece 2B can be used for avoiding the lattice part 22 of the other one, so that interference of the two lattice pieces 2 in the rotating process is avoided, normal and smooth rotation of the two lattice pieces 2 is ensured, and normal work of the throwing device 10 can be realized.

Through setting up the part of dividing grid 2 to including rotation portion 21 and a plurality of division portion 22 of arranging along rotation portion 21 circumference interval, can conveniently realize injecing a plurality of divisions 113 between the internal wall face of part of dividing grid 2 and casing 1 to division portion 22 can play the effect that promotes lotion 60 in the division 113, makes the transport of lotion 60 more laborsaving, also makes the simple structure and the convenient machine-shaping of the part of dividing grid 2 simultaneously. Because the grid grooves 23 are defined between two adjacent grid parts 22 of each grid part 2, in the rotating process of the two grid parts 2, the grid groove 23 of one grid part 2 can avoid the grid part 22 of the other grid part 2, so that the two grid parts 2 can be prevented from interfering in the rotating process, the two grid parts 2 can be ensured to rotate smoothly, and the detergent 60 can be ensured to be normally thrown in the throwing device 10.

This makes it possible to form a relatively closed cell area 113, so that a plurality of cell areas 113 are better spaced apart from each other, and to prevent or reduce the lotion 60 in one of the cell areas 113 from flowing into the other cell areas 113 through the gap between the first cell member 2 and the second cell member 2, thereby ensuring the accuracy of a single dose of lotion.

Specifically, during the rotation of the two compartments 2, the two compartments 2 can be fitted to each other in the following manner. For convenience of explanation, one of the two compartments 2 serves as a first compartment 2A and the other of the two compartments 2 serves as a second compartment 2B. During the rotation of the two cell pieces 2, the cell grooves 23 of the first cell piece 2A may escape the cell parts 22 of the second cell piece 2B, i.e., the cell parts 22 of the second cell piece 2B may be at least partially accommodated in the cell grooves 23 of the first cell piece 2A, and the cell parts 22 of the second cell piece 2B may be in contact with the inner walls of the cell grooves 23 of the first cell piece 2A; the cell groove 23 of the second cell piece 2B may escape the cell part 22 of the first cell piece 2A, i.e., the cell part 22 of the first cell piece 2A may be at least partially accommodated in the cell groove 23 of the second cell piece 2B, and the cell part 22 of the first cell piece 2A may be in contact with an inner wall of the cell groove 23 of the second cell piece 2B. This allows for better spacing between the multiple cells 113, and prevents or reduces the lotion 60 in one of the cells 113 from flowing into the other cells 113 through the gap between the first cell 2A and the second cell 2B, ensuring the accuracy of the single-dose lotion.

In the manufacturing process of the first cell piece 2A, the first cell piece may be manufactured from the first base cylinder 20, specifically, a part of the peripheral wall of the first base cylinder 20 may be recessed toward the central axis direction adjacent to the first base cylinder 20, and a part of the peripheral wall of the first base cylinder 20 may be recessed toward the central axis direction adjacent to the base cylinder 20 to form the above-mentioned cell groove 23, so that the first cell piece 2A is simple in structure and convenient to manufacture, and the formation of the cell groove 23 is facilitated, and at the same time, the volume of the cell groove 23 may be set large, which is beneficial to forming the cell area 113 with a large volume.

Similarly, the cell recesses 23 of the second cell piece 2B are formed by a part of the outer peripheral wall of the first base cylinder 20 being recessed toward the direction adjacent to the central axis of the first base cylinder 20, for example, a part of the outer peripheral contour of the first base cylinder 20 shown in fig. 7 and 9, which is a broken line, is a peripheral contour before the part of the outer peripheral wall of the first base cylinder 20 is not recessed, a part of the outer peripheral contour of the first base cylinder 20, which is a broken line, is recessed toward the inner wall surface of the cell recess 23, the other outer peripheral wall 24 of the first base cylinder 20 forms the first outer peripheral contour surface 2211 of the cell portion 22 of the second cell piece 2B, and the first outer peripheral contour surfaces 2211 of all the cell portions 22 of the second cell piece 2B are located on the cylindrical surface of the first base cylinder 20. In the manufacturing process of the second cell piece 2B, the first base cylinder 20 may be manufactured, specifically, a part of the peripheral wall of the first base cylinder 20 may be recessed toward the central axis direction adjacent to the first base cylinder 20, and a part of the peripheral wall of the first base cylinder 20 may be recessed toward the central axis direction adjacent to the first base cylinder 20 to form the cell groove 23, so that the second cell piece 2B is simple in structure and convenient to manufacture, and the cell groove 23 is convenient to form, and meanwhile, the volume of the cell groove 23 may be set to be large, which is beneficial to forming the cell area 113 with a large volume.

In some embodiments of the present invention, the circumferential length of the first outer circumferential contour surface 2211 is 1/4 of the circumferential length of the first base cylinder 20, so that the circumferential extension length of the first outer circumferential contour surface 2211 is larger, thereby increasing the matching area of the first outer circumferential contour surface 2211 and the inner circumferential surface of the housing 1, further reducing the leakage of the lotion 60 between the adjacent cells 113 through the gap between the first outer circumferential contour surface 2211 and the inner circumferential surface of the housing 1, better avoiding the leakage of the lotion 60 between the cells 113, and ensuring the accuracy of the amount of the lotion 60 administered at a time.

In some alternative embodiments of the present invention, referring to fig. 6 to 9, at least a portion of the inner circumferential surface of the housing 1 is formed as an arc-shaped surface that is curved in a direction away from the rotating portion 21, for example, a portion of the inner circumferential surface of the housing 1 may be formed as an arc-shaped surface, or the entire inner circumferential surface of the housing 1 may be formed as an arc-shaped surface. The first outer peripheral contoured surface 2211 is in sealing contact with the inner peripheral surface of the housing 1. By forming at least a part of the inner peripheral surface of the housing 1 as an arc-shaped surface curved toward a direction away from the rotating portion 21, the gap between the first outer peripheral contoured surface 2211 and the inner peripheral surface of the housing 1 can be reduced, so that a sealing contact fit can be formed between the first outer peripheral contoured surface 2211 and the inner peripheral surface of the housing 1 in the circumferential direction of the housing 1, leakage of the lotion 60 between the cells 113 is better avoided, and the accuracy of the amount of lotion 60 to be dispensed at a single time is ensured.

Further, with reference to fig. 7-12, the radius of the first base cylinder 20 is R1, the radius of the second base cylinder 210 is R2, and the length of the inner cavity 101 of the housing 1 is L, where L satisfies: l is not less than 4R1 and not less than 3R1+ R2. The length of the cavity 101 of the housing 1 is the dimension of the cavity 101 of the housing 1 in the direction of the line connecting the centers of the rotating parts 21 of the two lattices 2. By making the radius of the first base cylinder 20 of the lattice dividing member 2, the radius of the second base cylinder 210, and the length of the inner cavity 101 of the housing 1 satisfy the above-described relational expression, the lattice section 22 of one of the first lattice dividing member 2A and the second lattice dividing member 2B can be always positioned at least partially in the lattice recess 23 of the other of the first lattice dividing member 2A and the second lattice dividing member 2B during the rotation of the first lattice dividing member 2A and the second lattice dividing member 2B, so that the relatively closed lattice section 113 can be formed, and the size of the lattice section 113 changes with the rotation of the first lattice dividing member 2A and the second lattice dividing member 2B, so that the liquid suction and the liquid pumping are realized.

second lattice pieces

2A and 2B is adapted to be tangent to the first outer peripheral contour surface 2211 of the other of the first and

second lattice pieces

Thus, by fitting the fitting surface 211 of one of the first partition 2A and the second partition 2B in tangential contact with the first peripheral contour surface 2211 of the other of the first partition 2A and the second partition 2B, the plurality of partition 113 can be better spaced, and the lotion 60 in one of the partition 113 can be prevented or reduced from flowing into the other partition 113 through the gap between the first partition 2A and the second partition 2B, thereby ensuring the accuracy of the single-dose of the lotion. Moreover, the structure can reduce the friction and the abrasion between the two grid dividing pieces 2, and can also make the matching between the two grid dividing pieces 2 more compact, thereby making the structure of the throwing device 10 compact, being beneficial to the miniaturization of the throwing device 10 and reducing the occupied space.

Further, the structure of the tab portion 22 is simplified.

Similarly, referring to fig. 5 to 12, the cell portion 22 of the second cell member 2B further has a second peripheral contour surface 2212 and a third peripheral contour surface 2213, the second peripheral contour surface 2212 extends from one end of the first peripheral contour surface 2211 toward the rotating portion 21 and inward (the "inward" refers to a direction toward the center of the adjacent cell portion 22) in an arc shape and meets the rotating portion 21, the third peripheral contour surface 2213 extends from the other end of the first peripheral contour surface 2211 toward the rotating portion 21 and inward (the "inward" refers to a direction toward the center of the adjacent cell portion 22) in an arc shape and meets the rotating portion 21, and the first peripheral contour surface 2211, the second peripheral contour surface 2212 and the third peripheral contour surface 2213 surround and form the cell portion 22.

peripheral contour surfaces

2212 and 2213 are formed as arc-shaped surfaces recessed toward the center of the adjacent partition 22, the volume of the single partition groove 211 can be increased, and the volume of the single partition area 113 can be increased under a certain space in the housing 1, thereby increasing the amount of the lotion 60 to be dispensed in a single delivery. Further, the structure of the tab portion 22 is simplified.

According to some alternative embodiments of the invention, the first cell piece 2A may comprise 2-5 cell portions 22, for example the first cell piece 2A may comprise 2

cell portions

22, 3

cell portions

22, 4

cell portions

By setting the number of the cells 22 of the first cell member 2A to 2-5, it is possible to ensure the accuracy of the amount of the lotion 60 to be dispensed at a single time, and to make the volume of the single cell section 113 appropriate, thereby avoiding the volume of the single cell section 113 from being too small or too large to cause too much or too little of the amount of the lotion 60 to be dispensed at a single time. Moreover, the structure of the scoring piece 2 is simple, and the processing and the manufacturing are convenient.

According to some alternative embodiments of the present invention, referring to fig. 2 to 8, the first lattice piece 2A and the second lattice piece 2B are identical in shape and size. From this, can make the structure of two branch check spare 2 have stronger commonality to reduce the material kind, reduction in production cost, and make the cooperation each other between two branch check spare 2 more stable, reliable.

According to some alternative embodiments of the present invention, referring to fig. 2-8, the two compartments 2 are a first compartment 2A and a second compartment 2B, respectively, the first compartment 2A and the second compartment 2B are rotatable, and the rotation directions of the first compartment 2A and the second compartment 2B are opposite. The transmission assembly comprises a driving part 7 connected with the first division part 2A and a driven part 8 connected with the second division part 2B, the driving part 7 is meshed with the driven part 8, and the driving part 7 is suitable for being driven to drive the first division part 2A and the second division part 2B to rotate. When the driving part 7 is driven, through the meshing mutually of driving part 7 and follower 8, can drive follower 8 and rotate, thereby rotate through the drive driving part 7 and drive follower 8 and rotate, can guarantee like this that the meshing transmission power through driving part 7 and follower 8 between first minute lattice piece 2A and the second minute lattice piece 2B, guarantee that the relative rotation angle relation between first minute lattice piece 2A and the second minute lattice piece 2B is invariable, thereby can guarantee that first minute lattice piece 2A and second minute lattice piece 2B can rotate smoothly and can not take place to interfere.

In addition, in the initial installation state of the first division part 2A and the second division part 2B, it is necessary to ensure that the first division part 2A and the second division part 2B do not interfere with each other, for example, marks may be provided on the driving part 7 and the driven part 8 to ensure that the first division part 2A and the second division part 2B are installed according to a preset initial installation position, so that the first division part 2A and the second division part 2B can be installed more quickly and accurately.

In some alternative embodiments of the present invention, referring to fig. 2-8, the driving member 7 is a driving gear, the driven member 8 is a driven gear, the transmission assembly includes a driving member 3 and a transmission mechanism, the driving member 3 is movably disposed on the housing 1, the transmission mechanism is drivingly connected between the driving member 3 and the driving member 7, the transmission mechanism includes a driving rack 51 and a transmission gear 52 engaged with each other, the driving rack 51 is disposed on the driving member 3, the driving rack 51 is fixed relative to the driving member 3, for example, the driving rack 51 may be integrally formed with the driving member 3, and the transmission gear 52 is connected to the driving member 7, so that the driving connection between the driving member 3 and the driving member 7 can be realized. The driving member 3 is adapted to be driven to drive the first and second cells to rotate, when the dispensing device 10 needs to dispense the lotion 60, a user can apply an acting force to the driving member 3 to move the driving member 3, the driving member 3 drives the driving rack 51 to move synchronously, the driving gear 52 can be driven to rotate due to the engagement between the driving gear 52 and the driving rack 51, the driving gear 52 is connected to the driving member 7 to drive the driving member 7 to rotate, and the driving member 7 and the driven member 8 are engaged with each other to drive the driven member 8 to rotate, so that the lotion 60 is sucked from the liquid inlet 111 to the cell 113 and discharged from the liquid outlet 112. Therefore, the transmission of force can be conveniently realized by acting force on the driving part 3, so that the semi-automatic dispensing of the lotion 60 by the dispensing device 10 is realized, and the transmission mechanism is simple and facilitates the transmission of force.

In addition, because the movement of the first division part 2A is driven by the driving part 7, and the driving part 7 drives the driven part 8 to move so as to move the second division part 2B, the first division part 2A and the second division part are matched with each other, whether the movement of one division part 2 can drive the other division part 2 to move or not is not required to be considered, as long as the first division part 2A and the second division part 2B do not interfere in the movement process, and meanwhile, the plurality of defined division areas 113 are spaced from each other. Therefore, when the structures of the first lattice piece 2A and the second lattice piece 2B are designed, the structure of the lattice piece 2 can be simplified, the structural design limit of the lattice piece 2 is reduced, the requirement on the processing precision of the lattice piece 2 is lower, and the larger volume of the single lattice area 113 can be realized, so that the amount of the lotion put in a single transportation can be effectively increased, the putting times or the putting time of the lotion in a single transportation can be reduced, and the requirement on the putting of the lotion 60 by large-capacity washing equipment such as a washing machine and a dish washing machine can be met.

In some embodiments of the invention, the drive member 3 is movably disposed on the housing 1 between a first position and a second position. The user can apply effort to driving piece 3 for driving piece 3 moves to the second place by first position, and the motion through driving piece 3 drives the motion of drive mechanism, and drive mechanism drives the motion of box subassembly, thereby can conveniently realize the transmission of power through effort in driving piece 3, with the realization put in device 10 semi-automatically put in lotion 60. During the movement of the driving member 3 from the first position to the second position, a single administration of the lotion 60 can be achieved.

Alternatively, the actuator 3 is linearly moved by an external force applied by a user. It can be understood that the structure for realizing the linear motion of the driving member 3 is relatively simple, and the process of the linear motion is relatively simple, so that the reliability of the motion of the driving member 3 can be improved, and the complexity of the driving member 3 and the matching structure can be simplified, so that the processing cost of the driving member 3 and the matching structure can be reduced.

Of course, the invention is not limited thereto, and in other embodiments of the invention, the driving member 3 may also move curvilinearly under the action of an external force applied by a user. Alternatively, the actuator 3 may be moved in a combination of linear and curvilinear movements under the action of an external force applied by the user. Specifically, the movement trace of the driving member 3 under the action of the external force applied by the user can be designed according to the specific structure, model, size and working environment of the dispensing device 10.

After the driving member 3 has moved to the second position, the driving member 3 can be automatically reset to the first position, and the driving member 3 can also be reset to the first position under the reverse force of the user, i.e. the driving member 3 can also be manually reset to the first position. The resetting of the driving member 3 will be described below by taking as an example that the driving member 3 can be automatically reset to the first position.

For example, in some embodiments of the present invention, the driving member 3 and the transmission mechanism are drivingly connected between the driving member 3 and the driving member 7, the driving member 3 is movable between the first position and the second position, the transmission assembly further comprises an elastic restoring member 4, the elastic restoring member 4 may be a spring, and the elastic restoring member 4 is configured to drive the driving member 3 to return to the first position after the external force applied by the user is removed. It can be understood that, in the process that the driving member 3 moves from the first position to the second position under the action of the external force applied by the user, the elastic resetting member 4 can generate elastic deformation and apply the reverse elastic resetting force to the driving member 3, and when the user does not apply the external force to the driving member 3 any more, the driving member 3 can reset to the first position under the action of the elastic resetting force applied by the elastic resetting member 4. Therefore, the user does not need to manually reset the driving piece 3, and the use convenience of the user can be improved.
