[0048] The following will be combined with the drawings in the embodiments of this application to clearly and completely describe the technical solutions in the embodiments of this application. Obviously, the embodiments described are only part of the embodiments of this application, not all of the embodiments. Based on the embodiments of this application, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of this application.

[0049] It should be noted that all directional indications in the embodiments of the present application (such as up, down, left, right, front, back, etc.) are only used to explain the relative position relationship, movement status, etc. between the various components under a certain specific posture (as shown in the accompanying drawings). If the specific posture changes, the directional indication will also change accordingly.

[0050] In this application, unless otherwise specified or limited, the terms "connection" and "fixation" should be understood in a broad sense. For example, "fixation" can mean fixed connection, detachable connection, or integration; mechanical connection or electrical connection; direct connection or indirect connection through an intermediate medium; internal communication between two elements or interaction between two elements, unless otherwise specified. For those skilled in the art, the specific meanings of the above terms in this application can be understood according to specific circumstances.

[0051] In addition, the descriptions of "first", "second", etc. in this application are for descriptive purposes only and should not be understood as indicating or implying their relative importance or implicitly indicating the number of the technical features indicated. Therefore, the features defined as "first" or "second" may explicitly or implicitly include at least one of such features. In addition, the technical solutions between the various embodiments can be combined with each other, but this must be based on the fact that they can be implemented by ordinary technicians in this field. When the combination of technical solutions is contradictory or cannot be implemented, it should be deemed that such combination of technical solutions does not exist and is not within the scope of protection required by this application.

[0052] This application proposes a driving mechanism 1000, combined with Figure 1 、 Figure 2 、 Figures 4 to 9 、 Figure 11 、 Figure 13 and Figure 14 As shown, in some embodiments, the driving mechanism 1000 includes a power source 1100 , an input gear 1200 , an intermediate gear 1300 , a first output gear 1400 , and a second output gear 1500 .

[0053] The power source 1100 can move along the first direction and the second direction, that is, the power source 1100 can move along the first direction as well as the second direction. There are many types of power sources 1100. For example, the power source 1100 is a motor. The motor can convert electrical energy into mechanical energy. The motor can specifically be a stepper motor, a servo motor, etc. When the power source 1100 is a motor, the specific form of the motor being able to move along the first direction and the second direction is rotation, that is, the motor's shaft can rotate along the first direction as well as the second direction.

[0054] The power source 1100 is used to connect with the input gear 1200 to drive the input gear 1200 to rotate. Since the power source 1100 can move along the first direction and the second direction, the rotation direction of the input gear 1200 when the power source 1100 moves along the first direction is opposite to the rotation direction when the power source 1100 moves along the second direction.

[0055] The input gear 1200 is meshed with the intermediate gear 1300, and the input gear 1200 can drive the intermediate gear 1300 to rotate. Since the input gear 1200 has two opposite rotation directions, the input gear 1200 drives the intermediate gear 1300 to rotate, which also makes the intermediate gear 1300 have two opposite rotation directions. The different movements of the input gear 1200 when the power source 1100 moves in opposite directions also make the intermediate gear 1300 produce different movements, thereby driving the first output gear 1400 and the second output gear 1500 accordingly.

[0056] Specifically, when the power source 1100 moves in a first direction, the power source 1100 drives the input gear 1200 to rotate, and the rotation of the input gear 1200 drives the intermediate gear 1300 to rotate. At the same time, the input gear 1200 drives the intermediate gear 1300 to move to the first position, so that the intermediate gear 1300 meshes with the first output gear 1400 and drives the first output gear 1400 to rotate. When the power source 1100 moves in a second direction, the power source 1100 drives the input gear 1200 to rotate (in the opposite direction), and the rotation of the input gear 1200 drives the intermediate gear 1300 to rotate (in the opposite direction). At the same time, the input gear 1200 drives the intermediate gear 1300 to move to the second position, so that the intermediate gear 1300 meshes with the second output gear 1500 and drives the second output gear 1500 to rotate.

[0057] Taking the application of the driving mechanism 1000 to the dispensing device 100 as an example, the dispensing device 100 includes the driving mechanism 1000, a first actuator 2100 and a second actuator 2200. The first actuator 2100 is used to control the dispensing of the first detergent, and the second actuator 2200 is used to control the dispensing of the second detergent. That is, the dispensing device 100 is provided with positions for storing the first detergent and the second detergent, which are respectively a first cavity for storing the first detergent and a second cavity for storing the second detergent. The first actuator 2100 controls the dispensing of the first detergent, which means that under the activity of the first actuator 2100, the first detergent can be separated from the first cavity and directly or indirectly dispensed into the washing cavity. The second actuator 2200 controls the dispensing of the second detergent, which means that under the activity of the second actuator 2200, the second detergent can be separated from the second cavity and directly or indirectly dispensed into the washing cavity.

[0058] The movement of the first actuator 2100 and the second actuator 2200 is achieved through the drive mechanism 1000. The first output gear 1400 is connected to the first actuator 2100, and the second output gear 1500 is connected to the second actuator 2200. When the power source 1100 moves in a first direction, the intermediate gear 1300 moves to a first position to drive the first output gear 1400 to rotate. The first output gear 1400 drives the first actuator 2100 to move, thereby dispensing the first detergent. When the power source 1100 moves in a second direction, the intermediate gear 1300 moves to a second position to drive the second output gear 1500 to rotate. The second output gear 1500 drives the second actuator 2200 to move, thereby dispensing the second detergent. It can be understood that the first detergent is one of the detergents, and the second detergent is also one of the detergents. It can be a solid detergent or a liquid detergent. It can be mainly used for decontamination and cleaning, or it can be used to assist in decontamination and cleaning, such as dishwashing liquid, dishwashing powder, dishwashing blocks, dishwashing agents, deodorants, etc., and examples are not listed here one by one.

[0059] It can be seen that through the cooperation of the power source 1100, the input gear 1200, the intermediate gear 1300, the first output gear 1400 and the second output gear 1500, the intermediate gear 1300 can be moved to the first position and the second position. When the power source 1100 drives the intermediate gear 1300 to move to the first position, it can be output through the first output gear 1400, and the first output gear 1400 can drive the corresponding components to move to achieve the delivery of the corresponding detergent. When the power source 1100 drives the intermediate gear 1300 to move to the second position, it can be output through the second output gear 1500, and the second output gear 1500 can drive the corresponding components to move to achieve the delivery of the corresponding detergent. In this way, multiple detergents can be delivered through the same set of driving mechanisms 1000, which is conducive to reducing volume occupancy and reducing costs.

[0060] Combine Figure 11 and Figure 12As shown, in some embodiments, the drive mechanism 1000 further includes a base 1600, which is provided with a slide groove 1601, and the intermediate gear 1300 is supported in the slide groove 1601. The base 1600 rotatably supports the intermediate gear 1300. The base 1600 can be made of plastic or other materials. To meet different installation requirements, the base 1600 can have a regular or irregular shape. In this embodiment, a slide groove 1601 is provided on the base 1600, and the intermediate gear 1300 is supported on the slide groove 1601. The slide groove 1601 restricts the intermediate gear 1300. Since the intermediate gear 1300 needs to rotate under the drive of the input gear 1200, the restriction of the slide groove 1601 on the intermediate gear 1300 is reflected in that when the intermediate gear 1300 rotates, the intermediate gear 1300 will move along the slide groove 1601 and cannot escape from the slide groove 1601. In this way, it can move along the slide groove 1601 when the input gear 1200 rotates, thereby moving to the first position and the second position.

[0061] Specifically, the slide groove 1601 has a first end and a second end. When the power source 1100 moves along the first direction, the power source 1100 drives the input gear 1200 to rotate, and the rotation of the input gear 1200 drives the intermediate gear 1300 to rotate. During the rotation process, the intermediate gear 1300 will move along the slide groove 1601 until it moves to the first end and can no longer move. At this time, the intermediate gear 1300 is in the first position, and the intermediate gear 1300 is engaged with the first output gear 1400 to drive the first output gear 1400 to rotate. When the power source 1100 moves along the second direction, the power source 1100 drives the input gear 1200 to rotate (in the opposite direction of rotation), and the rotation of the input gear 1200 drives the intermediate gear 1300 to rotate (in the opposite direction of rotation). During the rotation process, the intermediate gear 1300 will move along the slide groove 1601 (move in the opposite direction) until it moves to the second end and can no longer move. At this time, the intermediate gear 1300 is in the second position, and the intermediate gear 1300 is engaged with the second output gear 1500 to drive the second output gear 1500 to rotate.

[0062] Optionally, the slide groove 1601 is designed to be linear, making it easier for the intermediate gear 1300 to reciprocate between the first position and the second position, shortening the moving path of the intermediate gear 1300, thereby shortening the time for switching to drive the first output gear 1400 and the second output gear 1500, which is conducive to quick response.

[0063] Combine Figure 12As shown, in some embodiments, the base 1600 includes a first base body 1610 and a second base body 1620, the first base body 1610 is provided with a slide groove 1601, and the second base body 1620 is also provided with a slide groove 1601, and a first pillar 1310 is provided on one axial side of the intermediate gear 1300, and a second pillar 1320 is provided on the other axial side of the intermediate gear 1300, the first pillar 1310 is inserted into the slide groove 1601 of the first base body 1610, and the second pillar 1320 is inserted into the slide groove 1601 of the second base body 1620, and the first base body 1610 and the second base body 1620 are connected to clamp the intermediate gear 1300 (the intermediate gear 1300 is provided between the first base body 1610 and the second base body 1620). The slide groove 1601 of the first base 1610 and the slide groove 1601 of the second base 1620 need to correspond. The slide groove 1601 of the first base 1610 can restrain the first pillar 1310 (on one axial side of the intermediate gear 1300), while the slide groove 1601 of the second base 1620 can restrain the second pillar 1320 (on the other axial side of the intermediate gear 1300). This ensures that when the intermediate gear 1300 rotates, the intermediate gear 1300 moves smoothly along the slide groove 1601 and is less likely to get stuck. In addition, the first base 1610 and the second base 1620 cooperate to provide rotatable support for the intermediate gear 1300, which also facilitates the lightweight design of the drive mechanism 1000.

[0064] Since the input gear 1200, the first output gear 1400 and the second output gear 1500 all need to be rotatable, based on the premise that the base 1600 includes the first base body 1610 and the second base body 1620, Figure 11 and Figure 12 As shown, in this embodiment, the input gear 1200, the first output gear 1400 and the second output gear 1500 are arranged between the first base body 1610 and the second base body 1620, so that they can rotate between the first base body 1610 and the second base body 1620. In this way, the various gear components are assembled together to prevent foreign matter from entering and causing the gear transmission to jam. It is understandable that there are various ways to connect the first base body 1610 and the second base body 1620, such as a snap connection, a screw connection, etc. The input gear 1200, the intermediate gear 1300, the first output gear 1400 and the second output gear 1500 can be first assembled on the first base body 1610 or the second base body 1620, and then the first base body 1610 and the second base body 1620 are connected together, so that the first base body 1610 and the second base body 1620 clamp the input gear 1200, the intermediate gear 1300, the first output gear 1400 and the second output gear 1500, so that the input gear 1200, the intermediate gear 1300, the first output gear 1400 and the second output gear 1500 can rotate in the base 1600.

[0065] Combine Figures 9 to 11 As shown, in some embodiments, the power source 1100 is disposed outside the base 1600. This arrangement allows the first base 1610 and the second base 1620 to fit together as flatly as possible, reducing structural complexity. Furthermore, the arrangement of the power source 1100 outside the base 1600 facilitates wiring operations for the power source 1100. In the structure shown in the accompanying drawings, the input gear 1200, the intermediate gear 1300, the first output gear 1400, and the second output gear 1500 are rotatably mounted within the base 1600 (between the first base 1610 and the second base 1620). The power source 1100 is disposed outside the base 1600 (outside the space enclosed by the first base 1610 and the second base 1620). A hole structure is provided in one of the first base 1610 and the second base 1620 to facilitate connection between the power source 1100 and the input gear 1200.

[0066] Combine Figure 10 As shown, in some embodiments, the central axis portion 1410 of the first output gear 1400 is exposed from the first base body 1610 and / or the second base body 1620. Since the first output gear 1400 is clamped by the first base body 1610 and the second base body 1620, and since the first output gear 1400 needs to be connected to a corresponding component (the first actuator 2100), in this embodiment, a hole structure is provided in the first base body 1610 and / or the second base body 1620, so that the central axis portion 1410 of the first output gear 1400 is exposed in the aforementioned hole structure. This facilitates the connection between the central axis portion 1410 of the first output gear 1400 and the corresponding component (the first actuator 2100), thereby driving the corresponding component to move. This configuration also facilitates the first output gear 1400 to be rotatable in conjunction with the aforementioned hole structure.

[0067] Similarly, combined Figure 10 As shown, in some embodiments, the central axis portion 1420 of the second output gear 1500 is exposed from the first base body 1610 and / or the second base body 1620. Since the second output gear 1500 is clamped by the first base body 1610 and the second base body 1620, and since the second output gear 1500 needs to be connected to a corresponding component (the second actuator 2200), in this embodiment, a hole structure is provided in the first base body 1610 and / or the second base body 1620, so that the central axis portion 1420 of the second output gear 1500 is exposed in the aforementioned hole structure. This facilitates the connection between the central axis portion 1420 of the second output gear 1500 and the corresponding component (the second actuator 2200), thereby driving the corresponding component to move. This arrangement also facilitates the second output gear 1500 to be rotatably arranged in conjunction with the aforementioned hole structure.

[0068] Combine Figure 13 and Figure 14 As shown, in some embodiments, the number of teeth of the first output gear 1400 is greater than the number of teeth of the second output gear 1500 . Generally speaking, the multiple detergents ("multiple" means two or more) dispensed by the dispensing device 100 are different detergents. For example, the first detergent is a liquid detergent and the second detergent is a solid detergent, or the first and second detergents are both liquid detergents but have different dispensing amounts and action properties. Therefore, the first actuator 2100 and the second actuator 2200 require different forces, speeds, and times to drive the first and second detergents. Since the first output gear 1400 and the second output gear 1500 are driven by the same gear, the number of teeth of the first output gear 1400 is designed to be greater than the number of teeth of the second output gear 1500. That is, the number of teeth of the first output gear 1400 is different from the number of teeth of the second output gear 1500. Therefore, the tooth ratio of the intermediate gear 1300 to the first output gear 1400 and the tooth ratio of the intermediate gear 1300 to the second output gear 1500 are different, thereby achieving different transmissions to accommodate the dispensing of different detergents.

[0069] Combine Figure 13 and Figure 14 As shown, in some embodiments, the number of teeth of the intermediate gear 1300 is less than the number of teeth of the first output gear 1400, thereby realizing reduction transmission. For example, the first output gear 1400 is used to drive the first actuator 2100 which is a pump body. The pump body includes but is not limited to a peristaltic pump, a piston pump, etc. Taking the pump body as a peristaltic pump as an example, through reduction transmission, the pump body can better absorb and discharge the corresponding detergent.

[0070] Combine Figure 13 and Figure 14 As shown, in some embodiments, the number of teeth of the intermediate gear 1300 is not less than the number of teeth of the second output gear 1500. The number of teeth of the intermediate gear 1300 can be equal to the number of teeth of the second output gear 1500, or the number of teeth of the intermediate gear 1300 can be greater than the number of teeth of the second output gear 1500. Through such a setting, the second output gear 1500, driven by the intermediate gear 1300, can achieve a rapid response of the corresponding component (the second actuator 2200).

[0071] Combine Figure 13 and Figure 14As shown, in some embodiments, the input gear 1200 has a greater number of teeth than the intermediate gear 1300. Since the intermediate gear 1300 needs to mesh with both the input gear 1200 and the first output gear 1400 to achieve transmission, and also needs to mesh with the input gear 1200 and the second output gear 1500 to achieve transmission, generally speaking, when other conditions remain unchanged, the greater the number of teeth, the larger the diameter of the entire gear. By designing the intermediate gear 1300 to have fewer teeth than the input gear 1200, the space occupied by the intermediate gear 1300 can be reduced. At the same time, this configuration can achieve a faster speed of the intermediate gear 1300.

[0072] Combine Figure 13 As shown, in some embodiments, a first straight line 3100 and a second straight line 3200 are defined. It can be understood that the first straight line 3100 and the second straight line 3200 are virtual lines defined for easier understanding of the solution. The first straight line 3100 connects the center of the first output gear 1400 and the center of the second output gear 1500. The second straight line 3200 passes through the midpoint of the first straight line 3100, and the second straight line 3200 is perpendicular to the first straight line 3100. The input gear 1200 is located on either side of the second straight line 3200, that is, the second straight line 3200 does not pass through the center of the input gear 1200. This is beneficial in some cases to reduce the space occupied by the drive mechanism 1000. It can be understood that if the center of the input gear 1200 is located on the second straight line 3200, the lines connecting the centers of the first output gear 1400, the second output gear 1500, and the input gear 1200 form an isosceles triangle. If the input gear 1200 is offset to either side of the second straight line 3200, in order to ensure the engagement between the input gear 1200 and the intermediate gear 1300, the input gear 1200 needs to be closer to the first output gear 1400 or the second output gear 1500 when offset to either side of the second straight line 3200. In this way, the space occupied in the extension direction of the second straight line 3200 can be reduced.

[0073] The second aspect of the present application discloses a delivery device 100, Figures 1 to 8As shown, the dispensing device 100 includes a first actuator 2100, a second actuator 2200 and the above-mentioned driving mechanism 1000. The first actuator 2100 is used to control the dispensing of the first detergent, and the second actuator 2200 is used to control the dispensing of the second detergent. That is, the dispensing device 100 is provided with positions for storing the first detergent and the second detergent, which are respectively a first cavity for storing the first detergent and a second cavity for storing the second detergent. The first actuator 2100 controls the dispensing of the first detergent, which means that under the activity of the first actuator 2100, the first detergent can be separated from the first cavity and directly or indirectly dispensed into the washing cavity. The second actuator 2200 controls the dispensing of the second detergent, which means that under the activity of the second actuator 2200, the second detergent can be separated from the second cavity and directly or indirectly dispensed into the washing cavity.

[0074] The movement of the first actuator 2100 and the second actuator 2200 is achieved through the drive mechanism 1000. The first output gear 1400 is connected to the first actuator 2100, and the second output gear 1500 is connected to the second actuator 2200. When the power source 1100 moves in a first direction, the intermediate gear 1300 moves to a first position to drive the first output gear 1400 to rotate. The first output gear 1400 drives the first actuator 2100 to move, thereby dispensing the first detergent. When the power source 1100 moves in a second direction, the intermediate gear 1300 moves to a second position to drive the second output gear 1500 to rotate. The second output gear 1500 drives the second actuator 2200 to move, thereby dispensing the second detergent.

[0075] Through the cooperation of the power source 1100, the input gear 1200, the intermediate gear 1300, the first output gear 1400, and the second output gear 1500, the intermediate gear 1300 can be moved to a first position and a second position. When the power source 1100 drives the intermediate gear 1300 to move to the first position, the output can be output through the first output gear 1400, and the first output gear 1400 can drive the corresponding components to operate, thereby achieving the dispensing of the corresponding detergent. When the power source 1100 drives the intermediate gear 1300 to move to the second position, the output can be output through the second output gear 1500, and the second output gear 1500 can drive the corresponding components to operate, thereby achieving the dispensing of the corresponding detergent. In this way, multiple detergents can be dispensed through the same set of driving mechanism 1000, which is beneficial for reducing the volume occupied and reducing costs. It can be understood that the driving mechanism 1000 of the dispensing device 100 of this embodiment adopts the technical solution of the above-mentioned embodiment, and therefore at least has the beneficial effects brought by the technical solution of the above-mentioned embodiment, which will not be repeated here.

[0076] Combine Figure 3 、 Figure 4and Figure 6 As shown, in some embodiments, the first actuator 2100 is located on one side of the delivery device 100, and the second actuator 2200 is located on the other side of the delivery device 100. The one side and the other side of the delivery device 100 are oriented toward each other in a third direction. Along the third direction, the center of the first output gear 1400 and the center of the second output gear 1500 are staggered.

[0077] Taking the case where the dispensing device 100 is installed on the door of a washing appliance as an example, when the door of the washing appliance is in a closed state, the dispensing device 100 is in a vertical state (see Figure 3 In this case, the first actuator 2100 is arranged on the right side of the delivery device 100, and the second actuator 2200 is arranged on the left side of the delivery device 100. That is to say, one side and the other side of the delivery device 100 are oriented in the left-right direction, that is, the third direction is the left-right direction. Along the left-right direction, the center of the first output gear 1400 and the center of the second output gear 1500 are staggered, which means that the center of the first output gear 1400 and the center of the second output gear 1500 are not collinear along the left-right direction ( Figure 3 In the embodiment, the center of the first output gear 1400 is lower, and the center of the second output gear 1500 is higher), and since the first output gear 1400 is used to drive the first actuator 2100, and the second output gear 1500 is used to drive the second actuator 2200, the first actuator 2100 and the second actuator 2200 can be staggered, thereby improving the utilization of space and reducing the left and right dimensions of the delivery device 100.

[0078] Combine Figures 1 to 4 As shown, in some embodiments, the drive mechanism 1000 is exposed on the back side 101 of the dispensing device 100. The dispensing device 100 is suitable for installation in the door of the washing appliance and conceals the back side 101. The drive mechanism 1000 is exposed on the back side 101 of the dispensing device 100. When the dispensing device 100 is installed in the door, the drive mechanism 1000 is concealed. During subsequent maintenance, the dispensing device 1000 can be disassembled and then the drive mechanism 1000 can be installed, thereby reducing the difficulty of repairing the drive mechanism 1000.

[0079] Combine Figure 2 、 Figure 3 and Figure 4As shown, in some embodiments, the dispensing device 100 is suitable for being installed on the door of the washing appliance. When the door is in the closed state, the driving mechanism 1000 is located below half the height of the dispensing device 100. It is understandable that the dispensing device 100 stores corresponding first and second detergents. When the door is in the closed state, the dispensing device 100 is arranged vertically. Under the action of gravity, the first and second detergents have a tendency to move downward in the storage space (first cavity, second container). By designing the driving mechanism 1000 to be located below half the height of the dispensing device 100, the first actuator 2100 and the second actuator 2200 can be close to the bottom of the storage space (first cavity, second container), thereby facilitating the control of the dispensing of the first and second detergents.

[0080] Combine Figure 4 As shown, in some embodiments, the thickness of the base 1600 of the drive mechanism 1000 is no greater than one-third of the thickness of the dispensing device 100. As can be seen from the above, the structural improvement of the base 1600 lays the foundation for achieving a lightweight and thin design, which helps to reduce the space occupied by the drive mechanism 1000 in the dispensing device 100. By designing the thickness of the base 1600 to be no greater than one-third of the thickness of the dispensing device 100, while the space occupied by the dispensing device 100 remains unchanged, the space occupied by the base 1600 for storing the first detergent and the second detergent is reduced.

[0081] The third aspect of the present application discloses a washing appliance, which may be a washing machine, a dishwasher, etc. The washing appliance includes the above-mentioned dispensing device 100, and the dispensing device 100 includes a first actuator 2100, a second actuator 2200 and a driving mechanism 1000. The dispensing device 100 of the washing appliance of this embodiment adopts the technical solution of the above-mentioned embodiment, and therefore has at least the beneficial effects brought by the technical solution of the above-mentioned embodiment, which will not be repeated here.

[0082] The above description is only a preferred embodiment of the present application and does not limit the patent scope of the present application. All equivalent structural transformations made based on the contents of the present application specification and drawings, or direct / indirect application in other related technical fields, are included in the patent protection scope of the present application.
