Detailed Description

Embodiments of the present invention are described in detail below, examples of which are illustrated in the accompanying drawings, wherein like or similar reference numerals refer to like or similar elements or elements having like or similar functions throughout. The embodiments described below by referring to the drawings are illustrative only and are not to be construed as limiting the invention.

A delivery device 10 according to an embodiment of the invention is described below with reference to fig. 1-13. The dispensing device 10 can be used in washing equipment with a water inlet system such as a washing machine, a dish washer, a wash station or a sink, the dispensing device 10 is used for dispensing a lotion 60, and the lotion can be liquid lotion 60 such as a laundry detergent and a softener.

The delivery device 10 according to an embodiment of the first aspect of the present invention comprises: a liquid inlet 111 and a liquid outlet 112, a shell 1, a grid assembly and a transmission assembly. Lotion 60 can enter interior chamber 101 of housing 1 from inlet 111 and exit from outlet 112. The cell assembly is movably arranged in the inner cavity 101 of the shell 1, and comprises two cell pieces 2, wherein the two cell pieces 2 are matched with each other. A plurality of mutually spaced-apart dividing areas 113 are defined between the two dividing elements 2 and the inner wall surface of the housing 1, the dividing areas 113 being used for temporarily storing the transported lotion 60.

Wherein, the arrangement of the two division pieces 2 in a mutually matched manner means that a plurality of division areas 113 which are mutually separated are defined between the two division pieces 2 and the inner wall surface of the shell 1 through the mutual matching of the two division pieces 2, and in the moving process of the two division pieces 2, the movement of the two division pieces 2 can not be interfered through the mutual matching of the two division pieces 2, so that the smooth movement of the two division pieces 2 is ensured, and the two division pieces 2 have no transmission relationship, namely, the movement of one division piece 2 can not drive the movement of the other division piece 2.

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

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

Specifically, the two cell pieces 2 in the cell assembly are moved under the drive of the transmission assembly. During the movement of the two compartments 2, the two compartments 2 cooperate with each other, so that a negative pressure can be generated in the vicinity of the inlet opening 111, and liquid, such as lotion 60, can enter the compartment 113 in the housing 1 through the inlet opening 111 under the action of the negative pressure and its own weight. As the cell 2 is moved by the drive of the transmission assembly, the lotion 60 entering the cell area 113 is moved to the liquid outlet 112 by the pushing of the moving cell 2. When the lotion 60 is brought to the liquid outlet 112, the movement and cooperation of the two cell members 2 can squeeze out the liquid in the cell zone 113, and finally discharge from the liquid outlet 112.

In this application, the motion of cell piece 2 is driven by drive assembly, transmits the lotion in the cell district 2 from inlet 111 to liquid outlet 112, and the cooperation motion of two cell pieces 2 can realize with washing 60 suction inlet 111 and with washing 60 discharge outlet 112. Therefore, in this application, drive the transmission that two division check piece motion realized the washing through drive assembly, the motion of two division check pieces simultaneously can promote imbibition and flowing back, consequently, the dynamics demand at the in-process of liquid input has been reduced in the design of this application.

It will be appreciated that when the dispensing device 10 is in the initial state (no lotion 60 is present in the compartment 113), a negative pressure may be generated at the inlet 111 as the transmission assembly drives the compartment, and the lotion 60 flows into the compartment 113 in the housing 1 through the inlet 111 and is transported to the outlet 112 by the pushing action of the compartment and is discharged from the outlet 112. During 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 60 can be discharged at the liquid outlet 112, after which 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 movement of the cell assembly to dispense the lotion 60, i.e. when the dispensing device 10 is operating normally.

And, a plurality of cell areas 113 are defined between the cell assembly and the inner wall surface of the housing 1, and in 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 areas 113, and the amount of the lotion 60 dispensed by the user at a time can be the amount of the lotion 60 contained in the single cell area 113, thereby making the amount of the lotion 60 dispensed at a time more accurate.

For example, in some examples of the present invention, referring to fig. 8-12 (fig. 8-12 show the process of feeding and discharging liquid from one of the cell areas 113, fig. 8 shows the feeding of liquid from one of the cell areas 113, fig. 9-10 show the process of transporting liquid from the cell area 113 in a direction adjacent to the liquid outlet under the driving of the cell 2, fig. 10-11 show the process of discharging liquid, fig. 11 shows the completion of dispensing the lotion from the cell area 113), a cell assembly is movably disposed in the housing 1, and a plurality of cell areas 113 are defined between the cell assembly and the inner wall surface of the housing 1. When the cell assembly moves to a position where one of the cell areas 113 is in communication with the liquid inlet 111 on the housing 1, the lotion 60 can flow into that cell area 113 through the liquid inlet 111. In the process that the cell assembly continues to move, the lotion 60 in the cell area 113 is pushed by the cell assembly towards the direction of the liquid outlet 112, and when the cell assembly moves to the position where the cell area 113 is communicated with the liquid outlet 112, the lotion 60 in the cell area 113 is discharged through the liquid outlet 112, so that the volume of the lotion 60 in a single dispensing can be the same as the volume of the single cell area 113, and the accuracy of the lotion 60 in a single dispensing can be improved.

The transmission assembly can move under the action of external force applied by a user, namely, when the user applies external force to the transmission assembly, the transmission assembly moves. The user may drive the movement of the cell assembly by manually driving the movement of the transmission assembly, thereby achieving a semi-automatic dispensing of the dispensing device 10, i.e. a manual dispensing of a metered amount of lotion 60. It can be appreciated that the motion of the transmission assembly is realized by the action of the external force applied by the user, so that other power sources for driving the transmission assembly to move are not required to be arranged in the throwing device 10, thereby saving the space of the throwing device 10, being beneficial to realizing the miniaturization of the throwing device 10 and reducing the manufacturing cost of the throwing device 10. Specifically, when the user needs to dispense the lotion 60, a 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, thereby realizing the dispensing of the lotion 60.

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

According to the dispensing device 10 of the embodiment of the invention, the dividing assembly is arranged, a plurality of dividing areas 113 are defined between the dividing assembly and the inner wall surface of the shell 1, the dividing assembly is arranged to comprise two dividing pieces 2 which are matched with each other, when the dispensing device 10 works normally, the two dividing pieces 2 are driven to move through the transmission assembly, the lotion 60 can be sucked into the dividing areas 113 from the liquid inlet 111, and the lotion 60 in the dividing areas 113 is brought to the liquid outlet 112 through the movement of the dividing pieces 2. The existing pump structure, such as a gear pump, has the advantages that the gear of the existing pump structure is required to realize both the transmission function and the liquid conveying function, and the transmission function ensures that the backlash of the existing pump structure cannot be set too large, otherwise, the transmission effect is influenced; the invention is realized by arranging the separate dividing element 2 for liquid transmission and the transmission of the dividing element is realized by the transmission component, so that the dividing area 113 can be arranged larger, thereby realizing the effect of improving the single infusion quantity.

According to some embodiments of the invention, referring to fig. 7-12, the volume of the individual cell regions 113 is variable during movement of the cell assembly. For example, during the movement of the cell assembly, when one of the cell regions 113 is in communication with the liquid inlet 111, during the short time that the cell region 113 is in communication with the liquid inlet 111, the volumes of the cell regions 113 can be changed by the movement and mutual cooperation of the two cell members 2, so that the volumes of the cell regions 113 are gradually increased, and thus negative pressure can be generated in the cell regions 113 (as shown in fig. 8), so that the lotion 60 can flow into the cell regions 113 from the liquid inlet 111.

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

During the movement of the cell assembly, the volume of the single cell region 113 can be changed, and negative pressure can be conveniently formed near the liquid inlet 111 and positive pressure can be conveniently formed near the liquid outlet 112, so that the suction and discharge of the lotion 60 are smoother.

According to some embodiments of the invention, the inlet 111 may be arranged higher than the outlet 112. It will be appreciated that liquid inlet 111 is positioned higher than liquid outlet 112 so that lotion 60 can be more easily thrown outwardly through liquid outlet 112 by gravity. Of course, the present invention is not limited thereto, and in another example of the present invention, the liquid inlet 111 may be equal to the liquid outlet 112 in height.

According to some embodiments of the present invention, referring to fig. 2 to 4 and 7, the cell region 113 extends in a direction perpendicular to the arrangement direction of the two cells 2, for example, the two cells 2 may be arranged in a left-right direction, and the cell region 113 may extend in an up-down direction. By making the extending direction of the dividing area 113 perpendicular to the arrangement direction of the two dividing pieces 2, it can be ensured that the extending space of the dividing area 113 does not affect 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. 2-13, two of the cell pieces 2 in the cell assembly may both rotate, and the rotation directions of the two cell pieces 2 are opposite, and a plurality of cell areas 113 may be defined between the outer peripheral contour surfaces of the two cell pieces 2 and the inner wall surface of the housing 1. By rotatably arranging the two dividing members 2 such that the movement of the dividing members 2 is simple and easy to realize, and such that the rotation directions of the two dividing members 2 are opposite, it is possible to conveniently realize the generation of negative pressure near the liquid inlet 111 and positive pressure near the liquid outlet 112, so that the suction and discharge of the lotion 60 can be conveniently realized.

According to some embodiments of the present invention, referring to fig. 5-7, two cell pieces 2 are rotatable, the two cell pieces 2 are a first cell piece 2A and a second cell piece 2B, respectively, and the first cell piece 2A and the second cell piece 2B each include: the rotation portion 21 and the plurality of dividing portions 22, the plurality of dividing portions 22 may be arranged at intervals along the circumferential direction of the rotation portion 21, dividing grooves 23 may be defined between two adjacent dividing portions 22, and an inner wall surface of the dividing grooves 23 may constitute a part of an inner wall surface of the dividing region 113. By providing the cell member 2 in the above-described configuration, a cell region 113 having a large volume can be defined between the cell member 2 and the inner wall surface of the casing 1, and the amount of lotion to be delivered per unit time can be increased.

In some alternative embodiments of the present invention, referring to fig. 5-7, each cell 2 comprises: the rotation portion 21 and the plurality of division portions 22, the plurality of division portions 22 can be arranged along the circumference interval of the rotation portion 21, the division portions 22 extend along the axial direction of the rotation portion 21, so that division grooves 23 defined between two division portions 22 extend along the axial direction of the division member 2, the volume of the division grooves 23 can be increased, and then the division areas 113 extending along the axial direction of the division member 2 can be defined between the outer circumference outline of the division member 2 and the inner wall of the shell 1, and the volume of the division areas 113 can be effectively increased.

For example, two cells 2 are arranged in the left-right direction, the rotation portion 21 of each cell 2 extends in the up-down direction, and the cell portion 22 of each cell 2 extends in the up-down direction, so that a cell region 113 extending in the up-down direction of the cell 2 is defined between the outer peripheral contour of the cell 2 and the inner wall of the housing 1. In the related art, if the amount of lotion to be dispensed in a single time is to be increased, the volume in the dispensing device needs to be changed, and after the volume in the dispensing device is increased, the driving force of the dispensing device to suck the lotion is increased. In this application, in order to increase the amount of detergent to be dispensed at a time, as shown in fig. 5, the cell area 113 is provided as a channel of the channel cell area 113 extending up and down may be made long. The larger the channel of the compartment 113, the more detergent is contained and the more detergent is dosed at a single time.

According to some alternative embodiments of the present invention, referring to fig. 5-7, two cells 2 are a first cell 2A and a second cell 2B, respectively, the first cell 2A and the second cell 2B each comprising: the rotation portion 21 and the plurality of lattice portions 22, the plurality of lattice portions 22 may be connected to the outer circumferential surface 212 of the rotation portion 21, the plurality of lattice portions 22 may be arranged at intervals along the circumferential direction of the rotation portion 21, for example, the plurality of lattice portions 22 may be arranged at uniform intervals along the circumferential direction of the rotation portion 21. One cell groove 23 may be defined between each adjacent two cell portions 22 of the first and second cell members 2A, 2B, at least a portion of the cell portions 22 of the first cell member 2A being adapted to be received within the cell groove 23 of the second cell member 2B, and/or at least a portion of the cell portions 22 of the second cell member 2B being adapted to be received within the cell groove 23 of the first cell member 2A. It may be that at least a part of the cell portion 22 of the first cell 2A is adapted to be received in the cell groove 23 of the second cell 2B, that at least a part of the cell portion 22 of the second cell 2B is adapted to be received in the cell groove 23 of the first cell 2A, that at least a part of the cell portion 22 of the first cell 2A is adapted to be received in the cell groove 23 of the second cell 2B and that at least a part of the cell portion 22 of the second cell 2B is adapted to be received in the cell groove 23 of the first cell 2A.

Referring to fig. 8-12, during rotation of the first and second pieces 2A, 2B, a partial stage may be where at least a portion of the tab portion 22 of the first piece 2A is adapted to be received within the tab recess 23 of the second piece 2B, and another partial stage may be where at least a portion of the tab portion 22 of the second piece 2B is adapted to be received within the tab recess 23 of the first piece 2A. In the process of rotating the two division pieces 2, at least one part of one division portion 22 of the first division piece 2A may be accommodated in one division groove 23 of the second division piece 2B, or at least one part of one division portion 22 of the second division piece 2B may be accommodated in one division groove 23 of the first division piece 2A, so as to realize mutually matched avoidance in the moving process of the two division pieces 2, thereby forming a relatively airtight division area and avoiding interference. In this way, in the process of rotating the first dividing element 2A and the second dividing element 2B, the dividing groove 23 of one of the first dividing element 2A and the second dividing element 2B can be used for avoiding the dividing portion 22 of the other dividing element, so that interference of the two dividing elements 2 in the process of rotating is avoided, normal and smooth rotation of the two dividing elements 2 is ensured, and normal operation of the throwing device 10 can be realized.

By arranging the cell 2 to include the rotating portion 21 and the plurality of cell portions 22 arranged at intervals along the circumferential direction of the rotating portion 21, it is possible to conveniently realize that a plurality of cell areas 113 are defined between the cell 2 and the inner wall surface of the housing 1, and the cell portions 22 can play a role of pushing the lotion 60 in the cell areas 113, so that the delivery of the lotion 60 is more labor-saving, and simultaneously, the structure of the cell 2 is simple and convenient to process and shape. Since the two adjacent dividing portions 22 of each dividing member 2 define the dividing grooves 23, in the process of rotating the two dividing members 2, the dividing grooves 23 of one dividing member 2 can avoid the dividing portion 22 of the other dividing member 2, so that interference of the two dividing members 2 in the rotating process can be avoided, smooth rotation of the two dividing members 2 is ensured, and accordingly, the normal feeding of the lotion 60 into the feeding device 10 can be ensured.

This results in a relatively closed compartment 113, which allows for better separation between the multiple compartments 113, avoiding or reducing the flow of lotion 60 in one compartment 113 into the other compartment 113 through the gap between the first and second compartments 2, ensuring the accuracy of a single dose of lotion.

Specifically, during the rotation of the two cell pieces 2, the two cell pieces 2 may be fitted to each other in the following manner. For convenience of explanation, one of the two pieces 2 is taken as a first piece 2A and the other of the two pieces 2 is taken as a second piece 2B. During rotation of the two pieces 2, the cell grooves 23 of the first piece 2A may avoid the cell portions 22 of the second piece 2B, i.e., the cell portions 22 of the second piece 2B may be at least partially accommodated within the cell grooves 23 of the first piece 2A, and the cell portions 22 of the second piece 2B may be in contact with the inner walls of the cell grooves 23 of the first piece 2A; the cell grooves 23 of the second cell 2B may avoid the cell portions 22 of the first cell 2A, i.e. the cell portions 22 of the first cell 2A may be at least partially accommodated within the cell grooves 23 of the second cell 2B, and the cell portions 22 of the first cell 2A may be in contact with the inner walls of the cell grooves 23 of the second cell 2B. This allows for better separation between the multiple cells 113, avoiding or reducing the flow of lotion 60 in one of the cells 113 into the other cell 113 through the gap between the first cell 2A and the second cell 2B, ensuring the accuracy of a single dose of lotion.

The first outer peripheral contoured surface 2211 is in sealing contact engagement 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 in a direction away from the rotating portion 21, the gap between the first outer peripheral profile 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 profile 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 divided areas 113 can be better avoided, and the accuracy of the amount of the lotion 60 administered once can be ensured.

Further, referring to fig. 7 to 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: 4R1 is more than or equal to L and is more than or equal to 3R1+R2. The length of the inner cavity 101 of the housing 1 refers to the dimension of the inner cavity 101 of the housing 1 in the direction of the central line of the rotation parts 21 of the two grid members 2. By making the radius of the first base cylinder 20 of the cell 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, during the rotation of the first cell 2A and the second cell 2B, the cell portion 22 of one of the first cell 2A and the second cell 2B can be made to be always located at least partially within the cell groove 23 of the other of the first cell 2A and the second cell 2B, so that a relatively closed cell 113 can be formed, and the size of the cell 113 changes with the rotation of the first cell 2A and the second cell 2B, thereby achieving liquid suction and pumping.

Thus, the matching surface 211 of one of the first and second division pieces 2A and 2B is in tangential contact fit with the first peripheral outline surface 2211 of the other of the first and second division pieces 2A and 2B, so that the division among the division areas 113 can be better separated, the lotion 60 in one division area 113 is prevented or reduced from flowing into the other division areas 113 through the gap between the first and second division pieces 2A and 2B, and the accuracy of single-administration of the lotion is ensured. Moreover, the structure can reduce friction and abrasion between the two grid pieces 2, and can further enable the cooperation between the two grid pieces 2 to be more compact, so that the structure of the throwing device 10 is compact, the miniaturization of the throwing device 10 is facilitated, and the occupied space is reduced.

In some embodiments of the present invention, referring to fig. 5-12, the cell portion 22 of the first cell 2A further has a second outer circumferential profile 2212 and a third outer circumferential profile 2213, the second outer circumferential profile 2212 extends arcuately from one end of the first outer circumferential profile 2211 toward the rotating portion 21 and inwardly (the "inward" refers to a direction toward a center adjacent to the cell portion 22) and is connected to the rotating portion 21, and the third outer circumferential profile 2213 extends arcuately from the other end of the first outer circumferential profile 2211 toward the rotating portion 21 and inwardly (the "inward" refers to a direction toward a center adjacent to the cell portion 22) and is connected to the rotating portion 21, and the first outer circumferential profile 2211, the second outer circumferential profile 2212, and the third outer circumferential profile 3 are provided around to form the cell portion 22. Since the second outer peripheral profile surface 2212 and the third outer peripheral profile surface 2213 of the first cell member 2A each extend inward in an arc shape, so that the second outer peripheral profile surface 2212 and the third outer peripheral profile surface 2213 are formed as arc surfaces recessed toward the center of the adjacent cell portion 22, the volume of the single cell recess 211 can be increased, and in a certain space condition within the housing 1, the volume of the single cell region 113 can be increased, so that the amount of the single-delivery-put lotion 60 can be increased. And, the structure of the cell portion 22 is made simple.

Similarly, referring to fig. 5 to 12, the cell portion 22 of the second cell 2B further has a second outer peripheral surface 2212 and a third outer peripheral surface 2213, the second outer peripheral surface 2212 extends arcuately from one end of the first outer peripheral surface 2211 toward the rotating portion 21 and inwardly (the "inward" refers to a direction toward the center of the adjacent cell portion 22) and is connected to the rotating portion 21, and the third outer peripheral surface 2213 extends arcuately from the other end of the first outer peripheral surface 2211 toward the rotating portion 21 and inwardly (the "inward" refers to a direction toward the center of the adjacent cell portion 22) and is connected to the rotating portion 21, and the first outer peripheral surface 2211, the second outer peripheral surface 2212 and the third outer peripheral surface 2213 are provided around to form the cell portion 22.

And, the structure of the cell portion 22 is made simple.

Thereby, the volume of the dividing groove 23 can be made larger, so that the volume of the single dividing region 113 defined between the first dividing member 2A and the inner wall of the housing 1 is made larger, so that the amount of the lotion 60 delivered in one time can be increased.

Similarly, referring to fig. 5 to 12, the second cell 2B includes two cell portions 22, the two cell portions 22 being symmetrically disposed on opposite sides of the rotating portion 21, the second outer peripheral contour surface 2212 of the two cell portions 22 and a part of the outer peripheral surface 212 of the rotating portion 21 forming an inner wall surface of one cell groove 23, and the third outer peripheral contour surface 2213 of the two cell portions 22 and another part of the outer peripheral surface 212 of the rotating portion 21 forming an inner wall surface of the other cell groove 23, so that the cell groove 23 is formed substantially in a "3" shape. Thereby, the volume of the dividing groove 23 can be made larger, so that the volume of the single dividing region 113 defined between the second dividing member 2B and the inner wall of the housing 1 is made larger, so that the amount of the lotion 60 delivered in one time can be increased.

According to some alternative embodiments of the present invention, the first cell 2A may comprise 2-5 cells 22, e.g. the first cell 2A may comprise 2 cells 22, 3 cells 22, 4 cells 22 or 5 cells 22. By setting the number of the cell portions 22 of the first cell member 2A between 2 to 5, the accuracy of the amount of the detergent to be administered once can be ensured, and the volume of the single cell region 113 can be made appropriate, and the excessive or insufficient amount of the detergent 60 to be administered once caused by excessively small or excessively large volume of the single cell region 113 can be avoided. And the structure of the dividing piece 2 is simple, and the processing and the manufacturing are convenient.

According to some alternative embodiments of the present invention, referring to fig. 2-8, the first and second cells 2A, 2B are identical in shape and size. Therefore, the structure of the two division pieces 2 has stronger universality, the material types are reduced, the production cost is reduced, and the mutual coordination between the two division pieces 2 is more stable and reliable.

According to some alternative embodiments of the present invention, referring to fig. 2-8, two dividing members 2 are a first dividing member 2A and a second dividing member 2B, respectively, the first dividing member 2A and the second dividing member 2B are rotatable, and the rotation directions of the first dividing member 2A and the second dividing member 2B are opposite. The transmission assembly comprises a driving piece 7 connected with the first dividing piece 2A and a driven piece 8 connected with the second dividing piece 2B, the driving piece 7 is meshed with the driven piece 8, and the driving piece 7 is suitable for being driven to drive the first dividing piece 2A and the second dividing piece 2B to rotate. When the driving piece 7 is driven, the driving piece 7 is meshed with the driven piece 8, so that the driven piece 8 can be driven to rotate, and the driven piece 8 is driven to rotate by driving the driving piece 7 to rotate, so that power can be transmitted between the first grid piece 2A and the second grid piece 2B through the meshing of the driving piece 7 and the driven piece 8, the relative rotation angle relation between the first grid piece 2A and the second grid piece 2B is ensured to be constant, and the first grid piece 2A and the second grid piece 2B can be ensured to smoothly rotate and cannot interfere.

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

In some alternative embodiments of the 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 comprises a driving member 3 and a transmission mechanism, the driving member 3 is movably arranged on the housing 1, the transmission mechanism is in transmission connection with the driving member 3 and the driving member 7, the transmission mechanism comprises a driving rack 51 and a transmission gear 52 which are meshed with each other, the driving rack 51 is arranged on the driving member 3, the driving rack 51 is fixed relative to the driving member 3, for example, the driving rack 51 can be integrally formed with the driving member 3, and the transmission gear 52 is connected to the driving member 7, so that transmission connection between the driving member 3 and the driving member 7 can be realized. The driving member 3 is suitable for being driven to drive the first dividing member and the second dividing member 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 enable the driving member 3 to move, the driving member 3 drives the driving rack 51 to move synchronously, the transmission gear 52 can be driven to rotate due to the engagement of the transmission gear 52 with the driving rack 51, the driving member 7 can be driven to rotate due to the connection of the transmission gear 52 with the driving member 7, and the driven member 8 is driven to rotate due to the engagement between the driving member 7 and the driven member 8, so that the lotion 60 is sucked into the dividing region 113 from the liquid inlet 111 and discharged from the liquid outlet 112. Therefore, force can be conveniently transmitted through acting force on the driving piece 3, so that the semi-automatic lotion 60 feeding of the feeding device 10 is realized, and the transmission mechanism is simple and convenient for force transmission.

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

In some embodiments of the invention, the driving member 3 is movably arranged 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 position by the first position, drives the drive mechanism motion through the motion of driving piece 3, and the drive mechanism drives the movement of division subassembly, thereby can conveniently realize the transmission of power in driving piece 3 through effort, in order to realize throwing device 10 semi-automatic throwing lotion 60. A single administration of lotion 60 can be achieved during the movement of the driving member 3 from the first position to the second position.

Alternatively, the driving member 3 moves linearly under the external force applied by the user. It will be appreciated that the structure for realizing the movement of the driving member 3 along the straight line is relatively simple, and the process of moving along the straight line is relatively simple, so that the reliability of the movement of the driving member 3 can be improved, and the complexity of the driving member 3 and the mating structure can be simplified, so that the processing cost of the driving member 3 and the mating 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 in a curved manner under the action of an external force applied by a user. Alternatively, the driving member 3 performs a combination of linear and curved motions under the external force applied by the user. Specifically, the motion track of the driving member 3 under the action of the external force applied by the user may be designed according to the specific structure, model, size and working environment of the delivery device 10.

After the driving member 3 moves to the second position, the driving member 3 may be automatically reset to the first position, or the driving member 3 may be reset to the first position under the reverse force of the user, that is, the driving member 3 may be manually reset to the first position. The following describes the resetting of the driving member 3, taking the case where the driving member 3 can be automatically reset to the first position as an example.

For example, in some embodiments of the 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 being movable between a first position and a second position, the transmission assembly further comprising an elastic return member 4, which may be a spring, the elastic return member 4 being adapted to drive the driving member 3 back to the first position after the external force applied by the user is removed. It will be appreciated that the elastic restoring member 4 may be elastically deformed during movement of the driving member 3 from the first position to the second position by an external force applied by a user, and a reverse elastic restoring force may be applied to the driving member 3, and when the external force is no longer applied to the driving member 3 by the user, the driving member 3 may be restored to the first position by the elastic restoring force applied by the elastic restoring member 4. Therefore, the driving piece 3 does not need to be reset manually by a user, and the convenience of the user can be improved.

According to some embodiments of the present invention, referring to fig. 2-7, the transmission assembly comprises a driving member 3 and a unidirectional transmission mechanism, the unidirectional transmission mechanism is in transmission connection between the driving member 3 and the driving member 7, the driving member 3 is movable between a first position and a second position, wherein, in the process of moving the driving member 3 from the first position to the second position, the driving member 3 drives the driving member 7 to move through the unidirectional transmission mechanism, the driving member 7 drives the cell assembly to move, in particular, drives the first cell member 2A and the second cell member 2B to rotate, so as to realize that the dispensing device 10 dispenses the lotion 60; in the course of the movement of the driving element 3 from the second position to the first position, the unidirectional transmission no longer transmits force to the driving element 7, so that the cell assembly is not driven to move, in particular the first cell element 2A and the second cell element 2B are not driven to rotate. Thereby helping to avoid reverse inhalation of the lotion 60 through the outlet 112 and helping to ensure the accuracy of the delivery of the lotion 60.

In some embodiments of the present invention, referring to fig. 2-6, the unidirectional transmission mechanism is a unidirectional rotation mechanism, wherein, in the process that the driving piece 3 moves from the first position to the second position, the unidirectional transmission mechanism rotates along the first rotation direction under the driving of the driving piece 3, drives the cell assembly to move, and realizes that the dispensing device 10 dispenses the lotion 60; in the course of the movement of the driving member 3 from the second position to the first position, the unidirectional transmission mechanism rotates in a second rotational direction opposite to the first rotational direction, and the unidirectional transmission mechanism no longer transmits force to the cell assembly, so that the cell assembly is not driven to move.

In some alternative embodiments of the present invention, referring to fig. 2-6, the first and second dividing members 2A and 2B are rotatable, and the transmission assembly includes the driving member 3, the transmission mechanism, the driving member 7 and the driven member 8 described above, where the transmission mechanism includes the driving rack 51 and the transmission gear 52 meshed with each other, and the unidirectional transmission mechanism described above is a unidirectional rotation mechanism, the unidirectional transmission mechanism includes the unidirectional transmission wheel 6, the driving member 7 is a driving gear, and the driven member 8 is a driven gear. The driving member 3 is slidably provided on the top of the housing 1 in the horizontal direction, the driving rack 51 is provided on the driving member 3, and the driving rack 51 extends in the sliding direction of the driving member 3. The driving piece 7 is connected to the first division piece 2A, the driving piece 7 is connected to one axial side of the first division piece 2A, and the driving piece 7 and the first division piece 2A can be coaxially arranged.

The driving piece 7 is internally provided with a matching cavity 71, the unidirectional driving wheel 6 is positioned in the matching cavity 71, and when the unidirectional driving wheel 6 rotates along the first rotation direction, the unidirectional driving wheel 6 is abutted with the inner wall of the matching cavity 71 so as to drive the driving piece 7 to rotate; when the unidirectional transmission wheel 6 rotates in a second rotation direction opposite to the first rotation direction, the unidirectional transmission wheel 6 is separated from transmission fit with the inner wall of the fit cavity 71. Wherein, "the unidirectional driving wheel 6 is separated from the inner wall of the matching cavity 71, it is understood that the unidirectional driving wheel 6 does not transmit a force for driving the driving member 7 to rotate to the inner wall of the matching cavity 71, for example, the unidirectional driving wheel 6 is separated from the inner wall of the matching cavity 71, or the unidirectional driving wheel 6 cannot drive the driving member 7 to rotate through the inner wall of the matching cavity 71 although the unidirectional driving wheel 6 is in contact with the matching cavity 71. By arranging the unidirectional transmission wheel 6 in the matching cavity 71, the space occupation of the driving piece 7 and the unidirectional transmission mechanism on the whole can be reduced, and meanwhile, the unidirectional transmission wheel 6 is abutted or separated with the inner wall of the matching cavity 71, so that the unidirectional transmission reliability of the unidirectional transmission mechanism can be guaranteed.

For example, in some embodiments of the present invention, referring to fig. 2 to 6, a first engagement tooth 72 is formed on an inner wall of the engagement cavity 71, the unidirectional transmission wheel 6 includes a transmission shaft 61 and a second engagement tooth 62 connected to the transmission shaft 61, and at least one of the first engagement tooth 72 and the second engagement tooth 62 has elasticity, in other words, one of the first engagement tooth 72 and the second engagement tooth 62 has elasticity, or both of the first engagement tooth 72 and the second engagement tooth 62 have elasticity. When the unidirectional transmission wheel 6 rotates in the first rotation direction, the second mating teeth 62 and the first mating teeth 72 are abutted at least in the circumferential direction to drive the driving piece 7 to rotate; the first mating teeth 72 and the second mating teeth 62 are disengaged when the unidirectional transmission wheel 6 rotates in a second rotational direction opposite to the first rotational direction. It will be appreciated that by making at least one of the first mating teeth 72 and the second mating teeth 62 an elastic member, it is advantageous to ensure that the first mating teeth 72 and the second mating teeth 62 are in a disengaged state when the unidirectional transmission wheel 6 rotates in the second rotational direction, thereby ensuring the reliability of the operation of the unidirectional transmission mechanism.

Alternatively, the cross section of each first mating tooth 72 is formed in a wedge shape, the plurality of first mating teeth 72 are uniformly spaced apart on the inner peripheral wall of the mating cavity 71, the first mating teeth 72 are rigid members, the second mating teeth 62 have elasticity, and when the unidirectional transmission wheel 6 rotates in the first rotation direction, the second mating teeth 62 and the first mating teeth 72 abut in the circumferential direction to drive the driving member 7 to rotate; when the unidirectional transmission wheel 6 rotates in the second rotational direction, the first mating teeth 72 and the second mating teeth 62 are disengaged.

Specifically, the elastic second mating teeth 62 may include a connection section 621 and a mating section 622, the connection section 621 being connected to the transmission shaft 61 and extending radially outward, the mating section 622 being connected to an end of the connection section 621 remote from the transmission shaft 61, the mating section 622 extending in a circumferential direction of the transmission shaft 61 and being spaced apart from the transmission shaft 61. It will be appreciated that by having the second mating teeth 62 include the connecting section 621 and the mating section 622, when the unidirectional drive wheel 6 rotates in the first rotational direction, the first mating teeth 72 are engaged with the mating section 622 in circumferential abutment, which is advantageous for ensuring the reliability of the abutment engagement between the first mating teeth 72 and the second mating teeth 62, and when the unidirectional drive wheel 6 rotates in the second rotational direction, the mating section 622 is deformable inwardly to allow the first mating teeth 72 to slip relative to the second mating teeth 62, which is advantageous for ensuring that the first mating teeth 72 and the second mating teeth 62 are disengaged from the drive engagement, thereby advantageously preventing the reverse liquid suction phenomenon from occurring.

In the process of sliding the driving member 3 from the first position to the second position, a single administration of the lotion 60 can be realized, and the single administration amount is large, and the administration number or single administration time can be reduced. Also, since the amount of lotion 60 contained in the cell area 113 is determined, the amount of lotion 60 can be precisely controlled for a single administration. For example, the amount of lotion 60 administered at a single time can be made more accurate by adjusting the distance between the first position and the second position such that the administration of lotion 60 in one compartment 113 is achieved during the sliding of the driving member 3 from the first position to the second position.
