[0061] In addition, the description such as "first", "second" and the like in the present application is only for the purpose of description, and cannot be understood as indicating or implying the relative importance of the indicated technical features or implicitly indicating the number of the indicated technical features. Therefore, the features defined as "first", "second" can be explicitly or implicitly included at least one of the features. In addition, the technical solutions of various embodiments can be combined with each other, but it must be based on the realization of ordinary skilled in the art, when the combination of technical solutions appears contradictory or unachievable, it should be considered that the combination of technical solutions does not exist, nor within the scope of protection claimed in the present application.

[0062] The first aspect of the present application discloses a dispensing device, in combination with Figure 1 、 Figure 2 and Figure 3 As shown, in some embodiments, the dispensing device comprises a first actuating mechanism 1000, a second actuating mechanism 2000, a third actuating mechanism 3000 and a driving mechanism 4000, the first actuating mechanism 1000 is used to control the dispensing of the first detergent, the second actuating mechanism 2000 is used to control the dispensing of the second detergent, and the third actuating mechanism 3000 is used to control the dispensing of the third detergent. That is, the dispensing device is provided with three positions for storing the first detergent, the second detergent and the third detergent respectively, which are a first cavity 6100 for storing the first detergent, a second cavity 6200 for storing the second detergent, and a third cavity 6300 for storing the third detergent. The first actuating mechanism 1000 controls the dispensing of the first detergent, which means that under the action of the first actuating mechanism 1000, the first detergent can be separated from the position for storing the first detergent (the first cavity 6100) and directly or indirectly dispensed into the washing cavity. The second actuating mechanism 2000 controls the dispensing of the second detergent, which means that under the action of the second actuating mechanism 2000, the second detergent can be separated from the position for storing the second detergent (the second cavity 6200) and directly or indirectly dispensed into the washing cavity. The third actuating mechanism 3000 controls the dispensing of the third detergent, which means that under the action of the third actuating mechanism 3000, the third detergent can be separated from the position for storing the detergent (the third cavity 6300) and directly or indirectly dispensed into the washing cavity.

[0063] The first detergent is one of the detergents, which can be designed for mainly stain removal cleaning. The second detergent is one of the detergents, which can be designed for mainly stain removal cleaning. The third detergent is one of the detergents, which can be designed for assisting stain removal cleaning, such as accelerating drying, increasing gloss, antibacterial, deodorizing, etc. It can be understood that the first detergent, the second detergent and the third detergent are not limited to the foregoing examples, but can also be other types. Taking the application of the dispensing device to the washing appliance as an example, the first detergent can be selected as a liquid detergent, such as dishwashing liquid. The second detergent can be selected as a solid detergent, such as dishwashing powder or dishwashing block. The third detergent can be selected as a liquid detergent, such as dishwashing liquid, deodorizing agent, etc.

[0064] The activities of the first actuator 1000, the second actuator 2000 and the third actuator 3000 need to be realized through the driving mechanism 4000. The driving mechanism 4000 is a component capable of outputting power. Through the arrangement of the driving mechanism 4000, the driving mechanism 4000 is suitable for driving the activities of the first actuator 1000, the second actuator 2000 and the third actuator 3000. It can be understood that the driving mechanism 4000 suitable for driving the activities of the first actuator 1000, the second actuator 2000 and the third actuator 3000 means that the driving mechanism 4000 can drive the first actuator 1000 to act when the first detergent needs to be dispensed, the driving mechanism 4000 can drive the second actuator 2000 to act when the second detergent needs to be dispensed, and the driving mechanism 4000 can drive the third actuator 3000 to act when the third detergent needs to be dispensed. When the driving mechanism 4000 drives the first actuator 1000 to act, the first actuator 1000 generates action to control the dispensing of the first detergent. When the driving mechanism 4000 drives the second actuator 2000 to act, the second actuator 2000 generates action to control the dispensing of the second detergent. When the driving mechanism 4000 drives the third actuator 3000 to act, the third actuator 3000 generates action to control the dispensing of the third detergent. It can be understood that under the driving of the driving mechanism 4000, the activities of the first actuator 1000, the second actuator 2000 and the third actuator 3000 can be in various forms, including but not limited to rotation, swinging, translation, curved motion, straight line reciprocating or compound motion (such as rotation first and then translation), etc. The activities of other components are also the same.

[0065] Take the application of the dispensing device to a washing appliance as an example, the washing appliance includes but is not limited to a dishwasher, and the dishwasher is specifically described in detail. It can be that the driving mechanism 4000 drives the first execution mechanism 1000 and the third execution mechanism 3000 to move, the driving mechanism 4000 drives the first execution mechanism 1000 to move, so that the first execution mechanism 1000 controls the first detergent dispensing, thereby realizing the decontamination cleaning of the dishes, and the driving mechanism 4000 drives the third execution mechanism 3000 to move, so that the third execution mechanism 3000 controls the third detergent dispensing, thereby improving the drying effect of the dishes and increasing the gloss of the dishes. It can also be that the driving mechanism 4000 drives the second execution mechanism 2000 and the third execution mechanism 3000 to move, the driving mechanism 4000 drives the second execution mechanism 2000 to move, so that the second execution mechanism 2000 controls the second detergent dispensing, thereby realizing the decontamination cleaning of the dishes, and the driving mechanism 4000 drives the third execution mechanism 3000 to move, so that the third execution mechanism 3000 controls the third detergent dispensing, thereby improving the drying effect of the dishes and increasing the gloss of the dishes.

[0066] As can be seen, the present embodiment sets the driving mechanism 4000, and the driving mechanism 4000 is configured to drive the first execution mechanism 1000, the second execution mechanism 2000 and the third execution mechanism 3000 to move. In this way, the dispensing of various types of detergents can be controlled under the action of the same set of driving mechanisms 4000, and compared with the dispensing device in the related art, the number of dispensing devices is greatly reduced, which is conducive to reducing the cost and the size of the dispensing device.

[0067] In combination Figures 4 to 7As shown, in some embodiments, the driving mechanism 4000 comprises a power source 4001 and a connecting assembly 4002, the power source 4001 and the connecting assembly 4002 cooperate to realize output, the connecting assembly 4002 plays a role in transmission between the power source 4001 and the execution mechanism (the first execution mechanism 1000, the second execution mechanism 2000, the third execution mechanism 3000). The power source 4001 is suitable for moving in a first direction and a second direction, the first direction and the second direction are opposite, that is, the power source 4001 can move in the first direction and the second direction. When the power source 4001 moves in the first direction, the power source 4001 is suitable for driving the connecting assembly 4002 to move, the movement of the connecting assembly 4002 drives the first execution mechanism 1000 to move, and the movement of the first execution mechanism 1000 controls the first detergent dispensing. When the power source 4001 moves in the second direction, the power source 4001 is suitable for driving the connecting assembly 4002 to move, the movement of the connecting assembly 4002 drives the second execution mechanism 2000 and the third execution mechanism 3000 to move, and the movement of the second execution mechanism 2000 controls the second detergent dispensing, and the movement of the third execution mechanism 3000 controls the third detergent dispensing.

[0068] In the present embodiment, the movement of the power source 4001 in the first direction and the movement of the power source 4001 in the second direction can drive the connecting assembly 4002 to produce different actions, that is, the action of the connecting assembly 4002 when the power source 4001 moves in the first direction is different from the action of the connecting assembly 4002 when the power source 4001 moves in the second direction, thereby realizing the driving of the corresponding first execution mechanism 1000, second execution mechanism 2000 and third execution mechanism 3000. The same power source 4001 can realize the selective dispensing of the dispensing device, which is conducive to reducing the structural complexity of the driving mechanism 4000. It can be understood that the movement of the power source 4001 in the first direction and the movement of the power source 4001 in the second direction can be rotation, translation and the like.

[0069] For example, as shown in the drawings, there is a power source 4001, the dispensing device stores the first detergent and the third detergent, and does not store the second detergent. When the first detergent and the third detergent are selected to be dispensed, the power source 4001 moves in the first direction, thereby driving the connecting assembly 4002 to move, so that the connecting assembly 4002 drives the first execution mechanism 1000 to move, and the movement of the first execution mechanism 1000 realizes the dispensing of the first detergent; the power source 4001 moves in the second direction, thereby driving the connecting assembly 4002 to move, so that the connecting assembly 4002 drives the second execution mechanism 2000 and the third execution mechanism 3000 to move, the second execution mechanism 2000 moves, and since the dispensing device does not store the second detergent, although the second execution mechanism 2000 moves, no second detergent is dispensed, and the third execution mechanism 3000 moves to realize the dispensing of the third detergent.

[0070] For example, as shown, a power source 4001 is provided, the dispensing device stores the second detergent and the third detergent, and stores or does not store the first detergent, when the second detergent and the third detergent are selected to be dispensed, the power source 4001 is moved in the second direction, thereby driving the connecting assembly 4002 to move, so that the connecting assembly 4002 drives the second actuating mechanism 2000 to move and the third actuating mechanism 3000 to move, the movement of the second actuating mechanism 2000 realizes the dispensing of the second detergent, and the movement of the third actuating mechanism 3000 realizes the dispensing of the third detergent.

[0071] In order to adapt to the different actions of the power source 4001 when it is moved in the first direction and in the second direction, the connecting assembly 4002 is further connected to the power source 4001, and the connecting assembly 4002 is further connected to the second actuating mechanism 2000 and the third actuating mechanism 3000. Figures 4 to 7 As shown, in some embodiments, the connecting assembly 4002 comprises an input member 4101, an intermediate member 4201, a first output member 4301 and a second output member 4401, the power source 4001 is connected to the input member 4101, and the power source 4001 can drive the input member 4101 to move, because the power source 4001 can be moved in the first direction and in the second direction, the action of the input member 4101 when the power source 4001 is moved in the first direction is different from the action of the input member 4101 when the power source 4001 is moved in the second direction, the input member 4101 is connected to the intermediate member 4201, and the input member 4101 can drive the intermediate member 4201 to move, the different actions of the input member 4101 when the power source 4001 is moved in opposite directions also cause the intermediate member 4201 to produce different actions, thereby corresponding to drive the first output member 4301 and the second output member 4401.

[0072] Specifically, when the power source 4001 moves in the first direction, the power source 4001 drives the input gear 4100 to move, the input gear 4100 drives the intermediate gear 4200 to move, at the same time, the input gear 4100 drives the intermediate gear 4200 to move to the first position, so that the intermediate gear 4200 cooperates with the first output gear 4300 and drives the first output gear 4300 to move, the first output gear 4300 moves and drives the first actuating mechanism 1000 to move, so as to realize the first detergent dispensing. When the power source 4001 moves in the second direction, the power source 4001 drives the input gear 4100 to move, the input gear 4100 drives the intermediate gear 4200 to move, at the same time, the input gear 4100 drives the intermediate gear 4200 to move to the second position, so that the intermediate gear 4200 cooperates with the second output gear 4400 and drives the second output gear 4400 to move, the second output gear 4400 moves and drives the second actuating mechanism 2000 and the third actuating mechanism 3000 to move, the second actuating mechanism 2000 moves to realize the second detergent dispensing, and the third actuating mechanism 3000 moves to realize the third detergent dispensing. It can be understood that the intermediate gear 4200 can reciprocate between the first position and the second position, the first position is the limit position of the intermediate gear 4200 when the power source 4001 moves in the first direction, and the second position is the limit position of the intermediate gear 4200 when the power source 4001 moves in the second direction, that is, the first position and the second position are the limit positions of the reciprocating movement of the intermediate gear 4200.

[0073] Further, continuing to combine Figures 4 to 7 As shown in the drawings, in some embodiments, the connecting assembly 4002 comprises an input gear 4100, an intermediate gear 4200, a first output gear 4300 and a second output gear 4400, the input gear 4100, the intermediate gear 4200, the first output gear 4300 and the second output gear 4400 are all configured to be rotatably arranged. It can be understood that the input gear 4100 constitutes the above-mentioned input gear 4101, the intermediate gear 4200 constitutes the above-mentioned intermediate gear 4201, the first output gear 4300 constitutes the above-mentioned first output gear 4301, and the second output gear 4400 constitutes the above-mentioned second output gear 4401.

[0074] The power source 4001 is connected with the input gear 4100, and the power source 4001 can drive the input gear 4100 to rotate. Since the power source 4001 can move along the first direction and the second direction, the rotating direction of the input gear 4100 when the power source 4001 moves along the first direction is opposite to the rotating direction of the power source 4001 when the power source 4001 moves along the second direction, that is, the input gear 4100 produces different actions. The input gear 4100 is engaged with the intermediate gear 4200, and the input gear 4100 can drive the intermediate gear 4200 to rotate. Since the input gear 4100 has two opposite rotating directions, the intermediate gear 4200 also has two opposite rotating directions. In this way, the input gear 4100 produces different actions when the power source 4001 moves along opposite directions, thereby also making the intermediate gear 4200 produce different actions, thereby corresponding to drive the first output 4301 and the second output 4401.

[0075] Specifically, when the power source 4001 moves along the first direction, the power source 4001 drives the input gear 4100 to rotate, and the input gear 4100 drives the intermediate gear 4200 to rotate. At the same time, the input gear 4100 drives the intermediate gear 4200 to move to the first position, so that the intermediate gear 4200 is engaged with the first output gear 4300 and drives the first output gear 4300 to rotate. The first output gear 4300 rotates to drive the first actuating mechanism 1000 to move, thereby realizing the first detergent dispensing. When the power source 4001 moves along the second direction, the power source 4001 drives the input gear 4100 to rotate, and the input gear 4100 drives the intermediate gear 4200 to rotate. At the same time, the input gear 4100 drives the intermediate gear 4200 to move to the second position, so that the intermediate gear 4200 is engaged with the second output gear 4400 and drives the second output gear 4400 to rotate. The second output gear 4400 rotates to drive the second actuating mechanism 2000 and the third actuating mechanism 3000 to move, the second actuating mechanism 2000 moves to realize the second detergent dispensing, and the third actuating mechanism 3000 moves to realize the third detergent dispensing.

[0076] The power source 4001 has various types, for example, the power source 4001 is an electric motor, which converts electrical energy into mechanical energy. The electric motor can be a stepper motor, a servo motor, etc. When the power source 4001 is an electric motor, the specific form in which the electric motor can move along the first direction and the second direction is rotation, that is, the rotating shaft of the electric motor can rotate along the first direction or the second direction. By configuring the power source 4001 as an electric motor, it is easier to control the movement of the connecting assembly 4002.

[0077] In combination Figures 5 to 8As shown, in some embodiments, the first execution mechanism 1000 comprises a pump body 1100, and the driving mechanism 4000 is adapted to drive the pump body 1100 to suck and discharge the first detergent. It can be understood that the pump body 1100, also known as a pump, is a machine that can suck and discharge fluid, and the type of pump body 1100 includes but is not limited to a peristaltic pump, a piston pump, etc. In the present embodiment, the first detergent is a liquid detergent, and when the first detergent needs to be dispensed, the driving mechanism 4000 drives the first execution mechanism 1000 to move, and the movement of the first execution mechanism 1000 is specifically manifested as the driving mechanism 4000 driving the corresponding structure of the pump body 1100 to move (such as driving the rotating shaft of the pump body 1100 to rotate), so that the pump body 1100 sucks the first detergent in the first cavity 6100 and discharges the first detergent, thereby realizing the dispensing of the first detergent.

[0078] It can be understood that the current dispensing device has different dispensing modes to realize the dispensing of the detergent in order to adapt to different similar washing appliances. With the product update and replacement of washing appliances, it is necessary to improve the dispensing mode of the dispensing device to meet more needs. Therefore, the driving mechanism 4000 driving the pump body 1100 can not only be applied to the dispensing device in the present application, but also be applied to other types of dispensing devices. For example, in another embodiment, the dispensing device comprises a driving mechanism 4000 and a first execution mechanism 1000, the first execution mechanism 1000 comprises a pump body 1100, and the driving mechanism 4000 is adapted to drive the rotating shaft of the pump body 1100 to rotate, so that the pump body 1100 sucks and discharges the first detergent.

[0079] Further, in combination with Figure 8 As shown, in some embodiments, the driving mechanism 4000 comprises a first output gear 4300, the first output gear 4300 is coaxially arranged with the rotating shaft of the pump body 1100, and the driving mechanism 4000 is adapted to drive the rotating shaft of the pump body 1100 to rotate through the first output gear 4300, so that the pump body 1100 sucks and discharges the first detergent.

[0080] Specifically, the first output gear 4300 is coaxial with the rotating shaft of the pump body 1100, so that the first output gear 4300 can drive the rotating shaft of the pump body 1100 to rotate coaxially, which is conducive to saving space. Taking the drive mechanism 4000 including the power source 4001 and the connecting assembly 4002 as an example, the connecting assembly 4002 including the input gear 4100, the intermediate gear 4200, the first output gear 4300 and the second output gear 4400, when the power source 4001 moves in the first direction, the power source 4001 drives the input gear 4100 to rotate, the input gear 4100 drives the intermediate gear 4200 to rotate, at the same time, the input gear 4100 drives the intermediate gear 4200 to move to the first position, so that the intermediate gear 4200 meshes with the first output gear 4300 and drives the first output gear 4300 to rotate, the first output gear 4300 rotates and drives the rotating shaft of the pump body 1100 to rotate, the pump body 1100 sucks in the first detergent and discharges the first detergent, thereby realizing the dispensing of the first detergent.

[0081] In combination with Figure 9 , Figure 10 , Figure 11 and Figure 13 , in some embodiments, the drive mechanism 4000 is adapted to drive the second execution mechanism 2000 to move, so that the second execution mechanism 2000 unlocks the cover 7100 of the dispensing device, and the cover 7100 opens the dispensing opening 6210 of the dispensing device to allow the second detergent to be dispensed from the dispensing opening 6210. It can be understood that the dispensing device is provided with a position (second cavity 6200) for storing the second detergent, the position (second cavity 6200) is formed with a dispensing opening 6210, and the dispensing device is provided with a cover 7100 for opening and closing the dispensing opening 6210. When the second detergent is placed in the position, the cover 7100 is closed to the dispensing opening 6210, and the second detergent cannot be dispensed from the dispensing opening 6210. When the cover 7100 is opened, the second detergent can leave the second cavity 6200 and be dispensed from the dispensing opening 6210 (i.e. the dispensing of the second detergent is realized). The cover 7100 is locked when it is in a state of closing the dispensing opening 6210, and when the cover 7100 is unlocked, the cover 7100 can be opened by the elastic member to open the dispensing opening 6210. In this embodiment, the second detergent is a solid detergent, and when the second detergent needs to be dispensed, the drive mechanism 4000 drives the second execution mechanism 2000 to move, so that the second execution mechanism 2000 unlocks the cover 7100, so that the cover 7100 opens the dispensing opening 6210, and the second detergent is dispensed from the dispensing opening 6210, such as under the action of gravity.

[0082] It can be understood that the current dispensing device has different dispensing modes to realize the dispensing of the detergent in order to adapt to different similar washing appliances. With the product update of the washing appliance, the dispensing mode of the dispensing device also needs to be improved to meet more needs. Therefore, the cooperation of the above-mentioned second actuating mechanism 2000 and the driving mechanism 4000 to unlock the cover body 7100 can not only be applied to the dispensing device in the present application, but also can be applied to other types of dispensing devices. For example, in another embodiment, the dispensing device comprises a driving mechanism 4000 and a second actuating mechanism 2000, the driving mechanism 4000 is adapted to drive the second actuating mechanism 2000 to move, so that the second actuating mechanism 2000 unlocks the cover body 7100 of the dispensing device, and the cover body 7100 opens the dispensing opening 6210 of the dispensing device to allow the second detergent to be dispensed from the dispensing opening 6210.

[0083] In combination with Figures 9 to 13 In some embodiments, the second actuating mechanism 2000 comprises a rotating shaft 2100 and a pawl 2200 arranged on the rotating shaft 2100, and the driving mechanism 4000 is adapted to be connected with the rotating shaft 2100 to drive the rotating shaft 2100 to rotate, and the pawl 2200 is adapted to rotate when the rotating shaft 2100 rotates to unlock the cover body 7100. The movement of the second actuating mechanism 2000 is specifically manifested as that the driving mechanism 4000 drives the second actuating mechanism 2000 to rotate, and more specifically, the driving mechanism 4000 drives the rotating shaft 2100 to rotate, so that the rotating shaft 2100 drives the pawl 2200 to rotate, and the pawl 2200 rotates to unlock the cover body 7100, thereby realizing the dispensing of the second detergent. Through the arrangement of the rotating shaft 2100 and the pawl 2200, the pawl 2200 can be arranged away from the driving mechanism 4000, which is more convenient for the arrangement of the structure.

[0084] In combination with Figure 14 、 Figure 15 and Figure 16 In some embodiments, the pawl 2200 is sleeved on the rotating shaft 2100, the peripheral wall of the rotating shaft 2100 is provided with a clamping protrusion 2110, and the pawl 2200 is provided with a gap 2210, the clamping protrusion 2110 is adapted to be clamped into the gap 2210 to enable the rotating shaft 2100 to drive the pawl 2200 to rotate. Through such an arrangement, the complexity of the cooperation between the rotating shaft 2100 and the pawl 2200 is reduced, which is beneficial to simplify the structure. Specifically, the clamping protrusion 2110 is clamped into the gap 2210, when the rotating shaft 2100 rotates, the clamping protrusion 2110 abuts against the wall of the gap 2210 along the rotating direction of the rotating shaft 2100, thereby driving the pawl 2200 to rotate.

[0085] Further, in combination with Figure 14 and Figure 15As shown, in some embodiments, the pawl 2200 is adapted to reciprocate along the rotating shaft 2100 between a third position and a fourth position; at the third position, the protrusion 2110 is engaged in the gap 2210; at the fourth position, the protrusion 2110 is disengaged from the gap 2210 so that the pawl 2200 and the rotating shaft 2100 can rotate relative to each other.

[0086] The pawl 2200 is movably coupled to the rotating shaft 2100, and the pawl 2200 can move along the rotating shaft 2100 to the third position and the fourth position, which are the limit positions of the reciprocating movement of the pawl 2200; when the pawl 2200 is at the third position, the protrusion 2110 is engaged in the gap 2210, and in this case, the rotating shaft 2100 can drive the pawl 2200 to rotate; when the pawl 2200 is at the fourth position, the protrusion 2110 is disengaged from the gap 2210, and when the rotating shaft 2100 rotates, the protrusion 2110 no longer abuts against the wall of the gap 2210 along the rotating direction of the rotating shaft 2100, so that the rotating shaft 2100 can no longer drive the pawl 2200 to rotate, i.e., the rotating shaft 2100 and the pawl 2200 can rotate relative to each other.

[0087] The driving mechanism 4000 is adapted to drive the rotating shaft 2100 to rotate when the pawl 2200 is at the third position, and the pawl 2200 is adapted to switch from the third position to the fourth position after unlocking the cover 7100. That is, when the second detergent needs to be dispensed, the pawl 2200 needs to be at the third position, the driving mechanism 4000 drives the rotating shaft 2100 to rotate, the rotating shaft 2100 drives the pawl 2200 to rotate, so that the pawl 2200 unlocks the cover 7100. In this embodiment, the pawl 2200 is adapted to switch from the third position to the fourth position after unlocking the cover 7100, i.e., after the rotating shaft 2100 drives the pawl 2200 to rotate by a certain angle, the pawl 2200 unlocks the cover 7100, the cover 7100 opens the dispensing opening 6210, and the pawl 2200 needs to switch from the third position to the fourth position, and if the driving mechanism 4000 continues to control the rotating shaft 2100 to rotate, the rotating shaft 2100 can no longer drive the pawl 2200 to rotate, so that the driving mechanism 4000 can continue to perform other actions without affecting the pawl 2200.

[0088] The movement of the pawl 2200 from the third position to the fourth position can be achieved by the first elastic member 5100, in combination with Figures 10 to 13As shown, in some embodiments, the dispensing device further comprises a first elastic member 5100, which is adapted to generate a force on the pawl 2200 to drive the pawl 2200 to switch from the third position to the fourth position after the pawl 2200 unlocks the cover 7100. That is, when the pawl 2200 is in the third position, the first elastic member 5100 is elastically deformed and accumulates elastic potential energy, at this time, the first elastic member 5100 generates a force on the pawl 2200, which makes the first elastic member 5100 have a tendency to switch from the third position to the fourth position. When the driving mechanism 4000 drives the rotating shaft 2100 to rotate, the rotating shaft 2100 drives the pawl 2200 to rotate so that the pawl 2200 unlocks the cover 7100, and after the cover 7100 opens the dispensing opening 6210 and separates from the pawl 2200, at this time, the first elastic member 5100 releases the elastic potential energy, so that the first elastic member 5100 switches from the third position to the fourth position. Optionally, the first elastic member 5100 is sleeved on the rotating shaft 2100, so that the arrangement of the first elastic member 5100 is more convenient. It can be understood that the first elastic member 5100 can be a spring, a pull rope, etc., and the second elastic member 5200 and the third elastic member 5300 are also the same, which will not be repeated here.

[0089] Further, continuing to combine Figures 10 to 13 As shown, in some embodiments, the cover 7100 drives the pawl 2200 to switch from the fourth position to the third position when the cover 7100 switches from the state of opening the dispensing opening 6210 to the state of closing the dispensing opening 6210. It can be understood that the cover 7100 can be electrically switched from the state of opening the dispensing opening 6210 to the state of closing the dispensing opening 6210, or it can be manually switched, for example, during the operation of the washing appliance, the cover 7100 is switched from the state of closing the dispensing opening 6210 to the state of opening the dispensing opening 6210, and after the operation of the washing appliance is completed, the user can re-place the second detergent and manually switch the cover 7100 to the state of closing the dispensing opening 6210, at this time, the cover 7100 cooperates with the pawl 2200 again. In order to realize the dispensing of the second detergent next time, in this embodiment, when the cover 7100 switches to the state of closing the dispensing opening 6210, the cover 7100 drives the pawl 2200 to switch from the fourth position to the third position, so that the pawl 2110 is clamped into the gap 2210, so that the rotating shaft 2100 can drive the pawl 2200 to rotate during the next dispensing of the second detergent. Optionally, the cover 7100 is provided with a protrusion 7120, and the cover 7100 is adapted to push the pawl 2200 through the protrusion 7120 to drive the pawl 2200 to switch from the fourth position to the third position, and the protrusion 7120 is provided to facilitate the pushing of the cover 7100 on the pawl 2200.

[0090] In combination Figures 10 to 13As shown, in some embodiments, the pawl 2200 is provided with a locking portion 2220, and the cover 7100 is provided with an abutting portion 7110, the locking portion 2220 is adapted to stop the abutting portion 7110 in the direction in which the cover 7100 opens the dispensing opening 6210 so that the cover 7100 is in the state of closing the dispensing opening 6210, and the locking portion 2220 is adapted to separate from the abutting portion 7110 when the pawl 2200 rotates so that the cover 7100 is switched from the state of closing the dispensing opening 6210 to the state of opening the dispensing opening 6210.

[0091] When the cover 7100 is in the state of closing the dispensing opening 6210, the locking portion 2220 stops the abutting portion 7110, and the second actuating mechanism 2000 locks the cover 7100, so the cover 7100 cannot move in the direction in which the cover 7100 opens the dispensing opening 6210, thus the cover 7100 cannot be switched from the state of closing the dispensing opening 6210 to the state of opening the dispensing opening 6210, i.e., the cover 7100 is maintained in the state of closing the dispensing opening 6210. When it is needed to dispense the second detergent, the driving mechanism 4000 controls the rotation of the rotating shaft 2100, the rotating shaft 2100 drives the pawl 2200 to rotate, and the rotation of the pawl 2200 makes the locking portion 2220 separate from the abutting portion 7110, i.e., the locking portion 2220 no longer stops the abutting portion 7110 in the direction in which the cover 7100 opens the dispensing opening 6210, thus the cover 7100 can be opened by the elastic member, so as to be switched from the state of closing the dispensing opening 6210 to the state of opening the dispensing opening 6210.

[0092] In combination Figures 10 to 13 As shown, in some embodiments, the dispensing device further comprises a second elastic member 5200, the second elastic member 5200 is adapted to generate a force on the pawl 2200 to generate a resisting force on the pawl 2200 when the pawl 2200 rotates to open the cover 7100. Specifically, when the rotating shaft 2100 drives the pawl 2200 to rotate to unlock the cover 7100, with the rotation of the pawl 2200, the second elastic member 5200 is elastically deformed to accumulate elastic potential energy and generate a resisting force on the pawl 2200, and after the pawl 2200 unlocks the cover 7100, the second elastic member 5200 can release the elastic potential energy to drive the pawl 2200 to reset in the direction opposite to the direction in which the pawl 2200 rotates to unlock the cover 7100, so as to facilitate the pawl 2200 to cooperate with the cover 7100 to lock the cover 7100 when the cover 7100 is closed again.

[0093] For example, when the driving mechanism 4000 drives the rotating shaft 2100 to rotate, the rotating shaft 2100 drives the pawl 2200 to rotate to unlock the cover 7100, and at the same time, the pawl 2200 makes the second elastic member 5200 elastically deform. After the cover 7100 opens the drop port 6210, the first elastic member 5100 releases the elastic potential energy to drive the pawl 2200 to move from the third position to the fourth position, and the second elastic member 5200 releases the elastic potential energy to drive the pawl 2200 to reset in the direction opposite to the direction of rotating the cover 7100.

[0094] Further, in some embodiments, when the cover 7100 switches from the state of opening the drop port 6210 to the state of closing the drop port 6210, the abutting portion 7110 of the cover 7100 touches the locking portion 2220 of the pawl 2200, so that the pawl 2200 rotates in the direction of unlocking the cover 7100 and then reversely rotates to stop the abutting portion 7110 in the direction of opening the drop port 6210.

[0095] Specifically, when the abutting portion 7110 touches the locking portion 2220 during the switching of the cover 7100 to the state of closing the drop port 6210, the abutting portion 7110 generates a component force on the locking portion 2220 through the improvement of the structures of the two portions, which drives the pawl 2200 to rotate in the direction of unlocking the cover 7100, so as to form an avoidance of the abutting portion 7110. At this time, the second elastic member 5200 elastically deforms, and as the cover 7100 moves to the position, the second elastic member 5200 releases the elastic potential energy (i.e. restores the deformation). The second elastic member 5200 generates a force on the pawl 2200 to drive the pawl 2200 to reset in the direction opposite to the direction of rotating the cover 7100, so as to stop the abutting portion 7110 in the direction of opening the drop port 6210, thereby maintaining the cover 7100 in the state of closing the drop port 6210.

[0096] In combination Figures 10 to 13 As shown, in some embodiments, the driving mechanism 4000 comprises a second output gear 4400, and the driving mechanism 4000 is adapted to drive the rotating shaft 2100 to rotate through the second output gear 4400. The second output gear 4400 is sleeved on the rotating shaft 2100 and is adapted to drive the rotating shaft 2100 to rotate when rotating. The second output gear 4400 is sleeved on the rotating shaft 2100, i.e. the second output gear 4400 is coaxially arranged with the rotating shaft 2100, so that the second output gear 4400 can coaxially drive the rotating shaft 2100 to rotate, which is beneficial to saving space. Figures 9 to 10 As shown, the third actuating mechanism 3000 is arranged between the second output gear 4400 and the pawl 2200, so as to fully utilize the space and make the structure of the drop device more compact.

[0097] The driving mechanism 4000 comprises a power source 4001 and a connecting assembly 4002, and the connecting assembly 4002 comprises an input gear 4100, an intermediate gear 4200, a first output gear 4300 and a second output gear 4400. When the power source 4001 moves in the second direction, the power source 4001 drives the input gear 4100 to rotate, and the input gear 4100 drives the intermediate gear 4200 to rotate. At the same time, the input gear 4100 drives the intermediate gear 4200 to move to the second position, so that the intermediate gear 4200 meshes with the second output gear 4400 and drives the second output gear 4400 to rotate. The second output gear 4400 rotates to drive the rotating shaft 2100 to rotate, and the rotating shaft 2100 rotates to drive the pawl 2200 to rotate, so that the pawl 2200 is unlocked to the cover 7100, thereby achieving the second detergent dispensing. It can be understood that when the pawl 2200 is unlocked to the cover 7100, the pawl 2200 is switched to the fourth position, and when the second output gear 4400 rotates to drive the third actuating mechanism 3000 to move, the rotating shaft 2100 also rotates, but the rotating shaft 2100 no longer drives the pawl 2200 to rotate.

[0098] In combination with Figure 5 、 Figure 6 、 Figure 7 、 Figure 9 、 Figure 10 、 Figure 17 and Figure 18 , in some embodiments, the driving mechanism 4000 is adapted to drive the third actuating mechanism 3000 to move, so that the third actuating mechanism 3000 is separated from the communication port 6310 of the dispensing device, and the third detergent flows out of the communication port 6310. It can be understood that the dispensing device is provided with a position (third cavity 6300) for storing the third detergent, and the position is provided with a communication port 6310. The third actuating mechanism 3000 is used to separate and block the communication port 6310. When the third detergent is placed in the position, the third actuating mechanism 3000 needs to block the communication port 6310, and the third detergent cannot leave the third cavity 6300 and flow out of the communication port 6310. When the third actuating mechanism 3000 is separated from the communication port 6310, the third detergent can flow out of the communication port 6310, thereby achieving the dispensing of the third detergent. In this embodiment, the third detergent is a liquid detergent such as a dish brightener. When the third detergent needs to be dispensed, the driving mechanism 4000 drives the third actuating mechanism 3000 to move, so that the third actuating mechanism 3000 is separated from the communication port 6310, and the third detergent flows out of the communication port 6310, thereby directly or indirectly achieving the dispensing.

[0099] It is understandable that current dispensing devices have different dispensing methods to adapt to different similar washing appliances. As washing appliances are upgraded, the dispensing methods of dispensing devices also need to be improved to meet more needs. Therefore, the above-mentioned third actuator 3000 and drive mechanism 4000 can be used not only in the dispensing device of this application, but also in other types of dispensing devices. For example, in other embodiments, the dispensing device includes a drive mechanism 4000 and a third actuator 3000, and the drive mechanism 4000 is suitable for driving the third actuator 3000 to move so that the third actuator 3000 is separated from the connecting port 6310 of the dispensing device and the third detergent flows out of the connecting port 6310.

[0100] Combine Figure 17 and Figure 8 As shown, in some embodiments, the third actuator 3000 is provided with a rack portion 3121, and the driving mechanism 4000 is adapted to engage with the rack portion 3121 to drive the movement of the third actuator 3000. The movement of the third actuator 3000 is specifically manifested by the driving mechanism 4000 driving the rack portion 3121, thereby causing the third actuator 3000 to move, thereby disengaging from the communication port 6310. The provision of the rack enables linear displacement of the third actuator 3000, more effectively disengaging from the communication port 6310.

[0101] Continue to combine Figure 17 and Figure 18 As shown, in some embodiments, the drive mechanism 4000 includes a second output gear 4400. The drive mechanism 4000 is adapted to drive the rack portion 3121 to move via the second output gear 4400. The second output gear 4400 is provided with a shifting tooth portion 4420. When the second output gear 4400 rotates, the shifting tooth portion 4420 is engaged with the rack portion 3121 to drive the third actuator 3000 to move. When the second output gear 4400 rotates, the shifting tooth portion 4420 rotates with it. Since the shifting tooth portion 4420 is engaged with the rack portion 3121, the rotation of the second output gear 4400 drives the rack portion 3121 to move. The movement of the rack portion 3121 can cause the third actuator 3000 to disengage from the communication port 6310.

[0102] The driving mechanism 4000 comprises a power source 4001 and a connecting assembly 4002, and the connecting assembly 4002 comprises an input gear 4100, an intermediate gear 4200, a first output gear 4300 and a second output gear 4400. When the power source 4001 moves in the second direction, the power source 4001 drives the input gear 4100 to rotate, and the input gear 4100 drives the intermediate gear 4200 to rotate. At the same time, the input gear 4100 drives the intermediate gear 4200 to move to the second position, so that the intermediate gear 4200 meshes with the second output gear 4400 and drives the second output gear 4400 to rotate. The second output gear 4400 rotates and drives the rack portion 3121 to move through the pawl portion 4420, and the rack portion 3121 moves to make the third actuating mechanism 3000 disengage from the communication port 6310, so as to realize the third detergent dispensing.

[0103] In some embodiments, the second output gear 4400 is provided with a tooth portion 4410, and the driving mechanism 4000 further comprises an input gear 4100 adapted to drive the second output gear 4400 to rotate through the tooth portion 4410. The tooth portion 4410 and the pawl portion 4420 are arranged along the axial direction of the second output gear 4400. Figure 17 Figure 18 In some embodiments, the second output gear 4400 is provided with a tooth portion 4410, and the driving mechanism 4000 further comprises an input gear 4100 adapted to drive the second output gear 4400 to rotate through the tooth portion 4410.
