[0053] The following will be combined with the drawings in the embodiments of the present application to clearly and completely describe the technical solutions in the embodiments of the present application. Obviously, the described embodiments are only part of the embodiments of the present application, not all of the embodiments. Based on the embodiments in the present application, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of this application.

[0054] 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 components under a certain specific posture (as shown in the accompanying drawings). If the specific posture changes, the directional indication will also change accordingly.

[0055] In this application, unless otherwise clearly specified and limited, the terms "connection", "fixation", etc. should be understood in a broad sense. For example, "fixation" can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection or an indirect connection through an intermediate medium, it can be the internal connection of two elements or the interaction relationship between two elements, unless otherwise clearly defined. For ordinary technicians in this field, the specific meanings of the above terms in this application can be understood according to specific circumstances.

[0056] In addition, in this application, descriptions such as "first", "second", etc. are only used for descriptive purposes and cannot be understood as indicating or implying their relative importance or implicitly indicating the number of technical features indicated. Therefore, the features defined as "first" and "second" may explicitly or implicitly include at least one of the features. In addition, the technical solutions between the various embodiments can be combined with each other, but they must be based on the ability of ordinary technicians in this field to implement them. 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.

[0057] The first aspect of the present application discloses a delivery device, Figures 1 to 9 As shown, in some embodiments, the dispensing device includes a driving mechanism 1000, a second actuator 2000, a third actuator 3000 and a trigger 4000, the driving mechanism 1000 includes a power source 1100 and an output component 1200, the power source 1100 is suitable for moving along a first direction to drive the output component 1200 to rotate, the output component 1200 is suitable for driving the second actuator 2000 to move when rotating, so that the second actuator 2000 controls the dispensing of the second detergent, the output component 1200 is suitable for driving the third actuator 3000 to move when rotating, so that the third actuator 3000 controls the dispensing of the third detergent, and the output component 1200 is suitable for touching the trigger 4000 to stop rotation when rotating.

[0058] The second actuator 2000 is used to control the placement of the second detergent, and the third actuator 3000 is used to control the placement of the third detergent, that is, the placement device is provided with two positions for storing the second detergent and the third detergent, respectively, namely, the second volume 6200 for storing the second detergent and the third volume 6300 for storing the third detergent. The second actuator 2000 controls the placement of the second detergent, which means that under the activity of the second actuator 2000, the second detergent can be separated from the position for storing the second detergent (the second volume 6200) and directly or indirectly placed in the washing chamber, and the third actuator 3000 controls the placement of the third detergent, which means that under the activity of the third actuator 3000, the third detergent can be separated from the position for storing the third detergent (the third volume 6300) and directly or indirectly placed in the washing chamber.

[0059] The second detergent is one of the detergents and can be designed to be mainly used for decontamination and cleaning. The third detergent is one of the detergents and can be designed to assist in decontamination and cleaning, such as accelerating drying, increasing gloss, antibacterial, deodorizing, etc. It can be understood that the second detergent and the third detergent are not limited to the aforementioned examples, and can also be other types. Taking the application of the dispensing device to a washing appliance as an example, the second detergent can be selected as a solid detergent, such as dishwashing powder or dishwashing blocks, and the third detergent can be selected as a liquid detergent, such as a rinse aid, a deodorant, etc.

[0060] The activities of the second actuator 2000 and the third actuator 3000 need to be realized through the driving mechanism 1000. The driving mechanism 1000 is a component that can output power. Through the setting of the driving mechanism 1000, the driving mechanism 1000 can drive the second actuator 2000 and the third actuator 3000 to move. The activities of the second actuator 2000 and the third actuator 3000 can be in various forms, including but not limited to rotation, swinging, translation, curved motion, linear reciprocating or compound motion (such as rotation first and then translation) and other forms. The same is true for the activities of other components.

[0061] Specifically, the driving mechanism 1000 includes a power source 1100 and an output component 1200. The power source 1100 is used to move along a first direction to drive the output component 1200 to rotate. The rotation of the output component 1200 drives the second actuator 2000 and the third actuator 3000 to move. The second actuator 2000 moves to achieve the second detergent delivery, and the third actuator 3000 moves to achieve the third detergent delivery. Whether the second actuator 2000 or the third actuator 3000 moves, it is achieved by the power source 1100 moving along the first direction. The power source 1100 does not need to be reversed, which is conducive to simplifying the control of the driving mechanism 1000. There are many types of power sources 1100. For example, the power source 1100 is a motor. The motor converts electrical energy into mechanical energy. The motor can be a stepper motor, a servo motor, etc. When the power source 1100 is a motor, the specific form of the movement of the power source 1100 along the first direction is rotation along the first direction, that is, the rotating shaft of the motor rotates along the first direction to drive the output component 1200 to rotate.

[0062] It can be seen that the driving mechanism 1000 can drive the second actuator 2000 and the third actuator 3000 to move through the output component 1200, so that the delivery of multiple types of detergents (multiple means two or more) can be controlled under the action of the same set of driving mechanism 1000. Compared with the delivery device in the related art, the number of driving mechanisms 1000 is greatly reduced, which is beneficial to reducing the cost of the delivery device and reducing the size of the delivery device.

[0063] In addition, the present embodiment is further provided with a trigger 4000, through which a signal can be triggered, for example, the trigger 4000 is a micro switch. Through the setting of the trigger 4000, when the output component 1200 rotates and touches the trigger 4000, the trigger 4000 triggers a signal, and the driving mechanism 1000 can be controlled to stop working according to the signal. The stopping of the driving mechanism 1000 means that the power source 1100 stops moving along the first direction, and the output component 1200 stops rotating, so that the position of the output component 1200 can be located.

[0064] For example, in the process from the output component 1200 starting to rotate to touching the trigger 4000 and stopping the rotation, the second actuator 2000 and the third actuator 3000 are driven to move, so as to achieve the delivery of the second detergent and the third detergent. The start of rotation can be understood as the output component changing from static to dynamic when the delivery of the detergent needs to be controlled. Generally speaking, there may be errors in the rotation of the output component 1200, such as the error in the movement of the power source 1100, which makes the rotation angle of the output component 1200 have errors. By setting the trigger 4000, since the position of the trigger 4000 is fixed, the output component 1200 touches the trigger 4000 and stops rotating, which corresponds to the same position (the first position 1222 where the protrusion 1211 is located). In this way, the position of the output component 1200 can be located and the rotation of the output component 1200 can be calibrated.

[0065] It can be understood that the output component 1200 touches the trigger 4000 to stop rotating, that is, the output component 1200 is controlled to stop rotating based on the triggered signal. The output component 1200 may stop rotating when the output component 1200 continues to touch the trigger 4000 (at this time, the trigger 4000 continues to trigger a signal), or the output component 1200 stops rotating after touching the trigger 4000 and continues to rotate a certain angle to pass the trigger 4000 (at this time, the trigger 4000 no longer triggers a signal).

[0066] Continue to combine Figures 1 to 9 In some embodiments, the output component 1200 includes a protrusion 1211, so that the protrusion 1211 is suitable for touching the trigger 4000 when rotating. The output component 1200 is suitable for driving the second actuator 2000 and the third actuator 3000 to move in sequence from the beginning of rotation to the protrusion 1211 touching the trigger 4000 and stopping the rotation.

[0067] The protrusion 1211 is a part of the output component 1200. When the output component 1200 rotates, the protrusion 1211 rotates accordingly. The trigger 4000 is set on the rotation path of the protrusion 1211. When the protrusion 1211 touches the trigger 4000, the output component 1200 can stop rotating. The output component 1200 rotates to drive the second actuator 2000 and the third actuator 3000 to move, which can be done simultaneously or in a time-sharing manner. In the present embodiment, the output component 1200 drives the second actuator 2000 and the third actuator 3000 to move in sequence when rotating, that is, the second actuator 2000 and the third actuator 3000 are not driven simultaneously, but in a time-sharing manner, and the second actuator 2000 is driven first, and then the third actuator 3000 is driven. Since different stages of the washing process require different detergents, by driving the second actuator 2000 and the third actuator 3000 in sequence, the second detergent is first added and then the third detergent is added, so as to meet the needs of different stages of the washing process. After the second detergent and the third detergent are added, as the output component 1200 rotates until the protrusion 1211 touches the trigger 4000, the output component 1200 stops rotating.

[0068] Combination Figure 8 , Fig. 9 and Fig.10 As shown, in some embodiments, the output component 1200 is suitable for starting to rotate when the protrusion 1211 is located at the first position 1222, and the protrusion 1211 is suitable for touching the trigger 4000 to stop the output component 1200 from rotating and is located at the first position 1222. In this way, the protrusion 1211 can be in the first position 1222 before and after the delivery device works, which makes it more convenient to control.

[0069] Taking the application of the dispensing device to a washing appliance as an example, the state before the dispensing device works, that is, when the washing appliance starts working but has not started to dispense detergent, can be understood as the dispensing device being in the initial state at this time, and the state after the dispensing device works, that is, when the dispensing device completes the dispensing of detergent, can be understood as the dispensing device being in the end state at this time. In this way, before dispensing detergent, the protrusion 1211 is in the first position 1222, and when the detergent starts to be dispensed, the output component 1200 starts to rotate, and at this time the protrusion 1211 starts to rotate from the first position 1222 (that is, the output component 1200 starts to rotate when the protrusion 1211 is in the first position 1222), until the protrusion 1211 rotates to touch the trigger 4000, the output component 1200 stops, and the protrusion 1211 returns to the first position 1222. In this process, the output component 1200 drives the second actuator 2000 and the third actuator 3000 to move in turn to achieve the dispensing of the second detergent and the third detergent. By such arrangement, each time the delivery device starts working and ends working, the protrusion 1211 is in the first position 1222 , thereby simplifying the rotation control of the output component 1200 .

[0070] Combination Fig.10 As shown, in some embodiments, the protrusion 1211 is suitable for touching the trigger 4000 to stop the output component 1200 from rotating and is located at the first position 1222 . The first position 1222 is formed within the range of the rotation angle α of the trigger 4000 along the rotation direction of the protrusion 1211 .

[0071] When the output component 1200 rotates until the protrusion 1211 touches the trigger 4000, the trigger 4000 triggers a signal and continues to control the output component 1200 to rotate a certain angle to reach the first position 1222. By designing the first position 1222 to have a certain angle range, the control accuracy requirement for the drive mechanism 1000 can be reduced. The angle α can be set according to actual conditions (such as according to the arrangement of the second actuator 2000 and the third actuator 3000). For example, the angle α can be 5° to 40°, or other angles. It can be understood that when the protrusion 1211 is in the first position 1222, the protrusion 1211 can be out of contact with the trigger 4000. The out of contact means that the trigger no longer triggers a signal, that is, the protrusion 1211 needs to pass over the trigger 4000 during the process of touching the trigger 4000 until the output component 1200 stops rotating.

[0072] Optionally, combined Fig.10As shown, in some embodiments, the output component 1200 is suitable for pausing rotation after driving the second actuator 2000 to move, and is suitable for rotating again after pausing rotation for a time T to drive the third actuator 3000 to move. In some washing processes, different stages require different times. Since different stages correspond to different detergents, in this embodiment, the output component 1200 first pauses rotation after driving the second actuator 2000 to move and put the second detergent, and waits until the current stage ends. The waiting time is T, that is, the pause rotation time is T. T can be set according to different washing processes, which can be 10 minutes, 20 minutes, 30 minutes or other times. After T ends, the washing process enters the next stage, so that the output component 1200 can be controlled to continue rotating to drive the third actuator 3000 to move to put the third detergent.

[0073] Taking the application of the dispensing device to a washing appliance as an example, the second detergent is dishwashing powder or dishwashing tablets, and the third detergent is a rinse aid. In the initial state (the state before the dispensing device works), the protrusion 1211 is in the first position 1222. When the second detergent needs to be dispensed, the output component 1200 rotates by an angle β to drive the second actuator 2000 to move (that is, the output component 1200 rotates by an angle β when the protrusion 1211 is in the first position 1222 to drive the second actuator 2000 to move), thereby dispensing the second detergent. At this time, the output component 1200 pauses to rotate for a time T to wait for the washing to enter the next stage, and then controls the output component 1200 to continue to rotate so as to drive the third actuator 3000 to move, thereby dispensing the third detergent, until the protrusion 1211 rotates to touch the trigger 4000, the rotating shaft 1220 stops rotating, and the protrusion 1211 returns to the first position 1222. The angle β can be set according to actual conditions (such as according to the arrangement of the second actuator 2000 and the third actuator 3000). The angle β can be 5° to 30°, or other angles. For example, the power source 1100 is a motor, and the motor can be a stepper motor, a servo motor, etc. In this way, the power source 1100 can control the rotation angle when rotating.

[0074] Combination Figure 1 , Figure 2 and Fig.11As shown, in some embodiments, the second actuator 2000 is suitable for unlocking the cover 7100 of the dispensing device when active, so that the cover 7100 opens the dispensing port 6210 of the dispensing device and the second detergent is dispensed from the dispensing port 6210. It can be understood that the dispensing device is provided with a position (second cavity 6200) for storing the second detergent, and the position (second cavity 6200) is formed with the dispensing port 6210, and the dispensing device is provided with a cover 7100 for opening and closing the dispensing port 6210. When the second detergent is placed in the position, the cover 7100 closes the dispensing port 6210, and the second detergent cannot be dispensed from the dispensing port 6210. The cover 7100 opens the dispensing port 6210, and the second detergent can leave the second cavity 6200 and be dispensed from the dispensing port 6210 (i.e., the dispensing of the second detergent is achieved). The cover 7100 is locked when it is in a state of closing the delivery port 6210. When the cover 7100 is unlocked, the cover 7100 can be opened under the action of the elastic member to open the delivery port 6210. In this embodiment, the second detergent is a solid detergent. When the second detergent needs to be delivered, the driving mechanism 1000 outputs it through the output component 1200, and the output component 1200 rotates to drive the second actuator 2000 to move, so that the second actuator 2000 unlocks the cover 7100, so that the cover 7100 opens the delivery port 6210, and the second detergent is delivered from the delivery port 6210, such as being delivered from the delivery port 6210 under the action of gravity.

[0075] Combination Figure 6 , Figure 7 and Fig.11 As shown, in some embodiments, the output component 1200 includes a rotating shaft 1220, and the second actuator 2000 includes a claw 2100 disposed on the rotating shaft 1220, and the claw 2100 is suitable for rotating when the rotating shaft 1220 rotates to unlock the cover 7100. The rotating shaft 1220 is a part of the output component 1200. When the output component 1200 rotates, the rotating shaft 1220 rotates, and the rotating shaft 1220 rotates to drive the claw 2100 to rotate, and the claw 2100 unlocks the cover 7100 in the form of rotation, so as to achieve the second detergent delivery.

[0076] Combination Fig.12 and Fig.13As shown, in some embodiments, the claw 2100 is sleeved on the rotating shaft 1220, the peripheral wall of the rotating shaft 1220 is provided with a clamping protrusion 1221, and the claw 2100 is provided with a notch 2110, and the clamping protrusion 1221 is suitable for clamping into the notch 2110 so that the rotating shaft 1220 can drive the claw 2100 to rotate. By such a configuration, the complexity of the matching between the rotating shaft 1220 and the claw 2100 is reduced, which is conducive to simplifying the structure. The clamping protrusion 1221 is clamped into the notch 2110. When the rotating shaft 1220 rotates, along the rotation direction of the rotating shaft 1220, the clamping protrusion 1221 abuts against the wall of the notch 2110, thereby driving the claw 2100 to rotate.

[0077] Combination Fig.11 , Fig.12 and Fig.13 As shown, in some embodiments, the claw 2100 is suitable for reciprocating along the rotating shaft 1220 between a third position and a fourth position; in the third position, the protrusion 1221 is engaged with the notch 2110; in the fourth position, the protrusion 1221 and the notch 2110 are separated so that the claw 2100 and the rotating shaft 1220 can rotate relative to each other.

[0078] The claw 2100 and the rotating shaft 1220 are movably matched, and the claw 2100 can move along the rotating shaft 1220 to a third position and a fourth position. The third position and the fourth position are the limit positions of the reciprocating movement of the claw 2100. When the claw 2100 is in the third position, the protrusion 1221 is inserted into the notch 2110. In this case, the rotating shaft 1220 can drive the claw 2100 to rotate to unlock the cover body 7100. When the claw 2100 is in the fourth position, the protrusion 1221 is separated from the notch 2110. When the rotating shaft 1220 rotates, along the rotation direction of the rotating shaft 1220, the protrusion 1221 no longer abuts against the wall of the notch 2110, so that the rotating shaft 1220 can no longer drive the claw 2100 to rotate, that is, the rotating shaft 1220 and the claw 2100 can rotate relative to each other at this time.

[0079] The rotating shaft 1220 is adapted to rotate when the claw 2100 is in the third position to unlock the cover 7100, and the claw 2100 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 put in, the claw 2100 needs to be in the third position, and the rotating shaft 1220 drives the claw 2100 to rotate, so that the claw 2100 unlocks the cover 7100. In this embodiment, the claw 2100 is adapted to switch from the third position to the fourth position after unlocking the cover 7100, that is, when the rotating shaft 1220 drives the claw 2100 to rotate to unlock the cover 7100, the cover 7100 opens the delivery port 6210, and the second detergent is thrown out from the delivery port 6210, at this time, the claw 2100 needs to switch from the third position to the fourth position, and when the subsequent rotating shaft 1220 continues to rotate, the rotating shaft 1220 can no longer drive the claw 2100 to rotate.

[0080] Optionally, the output component 1200 is suitable for driving the third actuator 3000 to move multiple times after the claw 2100 is switched to the fourth position, and multiple activities means two or more times. Since the rotation of the rotating shaft 1220 will no longer drive the claw 2100 to rotate after the claw 2100 is switched to the fourth position, the output component 1200 (rotating shaft 1220) can be controlled to rotate multiple times to drive the third actuator 3000 to move multiple times, thereby realizing multiple delivery of the third detergent, and multiple times means two or more times.

[0081] Taking the application of the dispensing device to a washing appliance as an example, the second detergent is dishwashing powder or dishwashing tablets, and the third detergent is a rinse aid. In the initial state (the state before the dispensing device works), the protrusion 1211 is in the first position 1222. When the second detergent needs to be dispensed, the output component 1200 (rotating shaft 1220) rotates by an angle β, and the rotating shaft 1220 drives the claw 2100 to rotate, thereby unlocking the cover 7100 and dispensing the second detergent. At this time, the claw 2100 switches from the third position to the fourth position, and the rotating shaft 1220 pauses for a rotation time T. After entering the next washing stage, the output component 1200 (rotating shaft 1220) is controlled to continue rotating, thereby driving the third actuator 3000 to move (because the claw 2100 is in In the fourth position, the rotating shaft 1220 no longer drives the claw 2100 to rotate), thereby realizing the first delivery of the third detergent, until the protrusion 1211 rotates to touch the trigger 4000, the output component 1200 (rotating shaft 1220) stops rotating, and the protrusion 1211 returns to the first position 1222. Subsequently, the output component 1200 (rotating shaft 1220) can be controlled to rotate until the protrusion 1211 returns to the first position 1222, thereby driving the third actuator 3000 to move again, thereby realizing the second delivery of the third detergent. This process is repeated, and the number of times the third detergent is delivered can be set according to actual needs.

[0082] The movement of the claw 2100 from the third position to the fourth position can be achieved by the first elastic member 5100, combined with Fig.11 As shown, in some embodiments, the delivery device further includes a first elastic member 5100, and the first elastic member 5100 is suitable for generating a force on the clamping claw 2100, so as to drive the clamping claw 2100 to switch from the third position to the fourth position after the clamping claw 2100 unlocks the cover body 7100. That is to say, when the clamping claw 2100 is in the third position, the first elastic member 5100 elastically deforms and accumulates elastic potential energy. At this time, the first elastic member 5100 generates a force on the clamping claw 2100, and the force makes the clamping claw 2100 have a tendency to switch from the third position to the fourth position. The rotating shaft 1220 drives the clamping claw 2100 to rotate so that the clamping claw 2100 unlocks the cover body 7100, and the cover body 7100 opens the delivery port 6210 and separates from the clamping claw 2100. At this time, the first elastic member 5100 releases the elastic potential energy, so that the clamping claw 2100 switches from the third position to the fourth position. Optionally, the first elastic member 5100 is sleeved on the rotating shaft 1220, which makes it easier to arrange the first elastic member 5100. It is understandable that the first elastic member 5100 can be a spring, a pull rope, etc., and the same is true for other elastic members, which will not be repeated.

[0083] Combination Figure 6 , Fig.11 , Fig.12 and Fig.13 As shown, in some embodiments, when the cover 7100 switches from the state of opening the delivery port 6210 to the state of closing the delivery port 6210, it drives the claw 2100 to switch from the fourth position to the third position. It is understandable that the switch of the cover 7100 from the state of opening the delivery port 6210 to the state of closing the delivery port 6210 can be realized electrically or manually. For example, during the operation of the washing appliance, the cover 7100 switches from the state of closing the delivery port 6210 to the state of opening the delivery port 6210 to realize the delivery of the second detergent. After the washing appliance is finished, the user can re-place the second detergent and manually switch the cover 7100 to the state of closing the delivery port 6210, at which time the cover 7100 is matched with the claw 2100 again.

[0084] In order to achieve the next delivery of the second detergent, in this embodiment, when the cover 7100 is switched to the state of closing the delivery port 6210, the cover 7100 drives the claw 2100 to switch from the fourth position to the third position, so that the protrusion 1221 is engaged in the notch 2110, so that when the second detergent is delivered next time, the rotating shaft 1220 can drive the claw 2100 to rotate and unlock the cover 7100. Optionally, the cover 7100 is provided with a convex portion 7120, and the cover 7100 is suitable for pushing the claw 2100 through the convex portion 7120, so that the claw 2100 is switched from the fourth position to the third position, and the provision of the convex portion 7120 makes it easier to achieve the cover 7100 pushing the claw 2100.

[0085] In some embodiments, when the cover body 7100 switches from a state of opening the delivery port 6210 to a state of closing the delivery port 6210, the protrusion 1211 of the output component 1200 is located in the first position 1222, that is, when the protrusion 1211 is located in the first position 1222, the latch 1221 corresponds to the notch 2110. Since the protrusion 1211 reaches the first position 1222 through the trigger 4000, the position is accurate, thereby ensuring that when the cover body 7100 switches to a state of closing the delivery port 6210, the latch claw 2100 can be pushed to switch from the fourth position to the third position.

[0086] The claw 2100 can reciprocate between the third position and the fourth position only when the protrusion 1221 and the notch 2110 correspond to each other. It can be seen from the above that when the rotating shaft 1220 drives the claw 2100 to rotate to unlock the cover body 7100, the claw 2100 switches to the fourth position. Thereafter, the output component 1200 (rotating shaft 1220) needs to continue to rotate to drive the third actuator 3000 to move. At this time, the rotating shaft 1220 will not drive the claw 2100 to rotate. During this process, the relative positions of the protrusion 1221 and the notch 2110 change. How to ensure that the protrusion 1221 corresponds to the notch 2110 again becomes the key. In this embodiment, the positional relationship between the latching protrusion 1221 and the notch 2110 is located by the protrusion 1211 being in the first position 1222. As mentioned above, the first position 1222 is more accurate. By the protrusion 1211 being in the first position 1222, it can be determined that the latching protrusion 1221 corresponds to the notch 2110. In this way, when the cover body 7100 is switched to the state of closing the delivery port 6210, the cover body 7100 can push the claw 2100 to switch from the fourth position to the third position.

[0087] Optionally, combined Fig.12 , Fig.13 and Fig.14As shown, along the circumference of the rotating shaft 1220 (i.e., the rotating direction of the rotating shaft 1220), the angle between the two opposite sides of the clamping protrusion 1221 is smaller than the angle between the two opposite sides of the notch 2110, that is, there is a gap between the clamping protrusion 1221 and the wall of the notch 2110. Fig.14 As shown, the angle between the two opposite sides of the latch 1221 is γ1, and the angle between the two opposite sides of the notch 2110 is γ2, γ2 is greater than γ1. When the first position 1222 is within the range formed by the angle α, due to the error of the power source 1100 in controlling the rotation of the output component 1200, the protrusion 1211 can stop at any position within the range of the first position 1222 (within the range of the angle α). By making the angle between the two opposite sides of the latch 1221 smaller than the angle between the two opposite sides of the notch 2110, the latch 1221 and the notch 2110 are not likely to interfere with each other when the claw 2100 moves from the fourth position to the third position. In particular, the angle between the two opposite sides of the notch 2110 can be designed to be no less than angle α (γ2 is no less than α). In this way, even when the protrusion 1211 is located at the edge of the range of the first position 1222 (the edge of the range of angle α), the protrusion 1221 and the notch 2110 can be smoothly matched when the claw 2100 moves from the fourth position to the third position.

[0088] Combination Figure 6 , Figure 7 , Fig.11 and Fig.15 As shown, in some embodiments, the claw 2100 is provided with a locking portion 2120, and the cover body 7100 has a butting portion 7110. The locking portion 2120 is suitable for stopping the butting portion 7110 in the direction in which the cover body 7100 opens the delivery port 6210 so that the cover body 7100 is in a state of closing the delivery port 6210. The locking portion 2120 is suitable for separating from the butting portion 7110 when the claw 2100 rotates so that the cover body 7100 is switched from the state of closing the delivery port 6210 to the state of opening the delivery port 6210.

[0089] When the cover 7100 is in the state of closing the delivery port 6210, the locking portion 2120 stops the abutting portion 7110, and the second actuator 2000 (claw 2100) locks the cover 7100, so that the cover 7100 cannot move in the direction of opening the delivery port 6210, so that the cover 7100 cannot switch from the state of closing the delivery port 6210 to the state of opening the delivery port 6210, that is, the cover 7100 maintains the state of closing the delivery port 6210. When the second detergent needs to be delivered, the rotating shaft 1220 drives the claw 2100 to rotate, and the claw 2100 rotates so that the locking portion 2120 is separated from the abutting portion 7110, that is, the locking portion 2120 no longer stops the abutting portion 7110 in the direction of the cover 7100 opening the delivery port 6210, so that the cover 7100 can be bounced open under the action of the elastic member, thereby switching from the state of closing the delivery port 6210 to the state of opening the delivery port 6210.

[0090] Combination Figure 6 , Figure 8 and Fig.11 As shown, in some embodiments, the delivery device further includes a second elastic member 5200, which is suitable for generating a force on the claw 2100 to generate a force to hinder the claw 2100 when the claw 2100 rotates to open the cover 7100. Specifically, when the rotating shaft 1220 drives the claw 2100 to rotate to unlock the cover 7100, as the claw 2100 rotates, the second elastic member 5200 generates elastic deformation to accumulate elastic potential energy and generate a force to hinder the claw 2100. After the claw 2100 unlocks the cover 7100, the second elastic member 5200 can release the elastic potential energy to drive the claw 2100 to reset in the opposite direction of the rotation direction of the unlocking cover 7100, so that when the cover 7100 closes the delivery port 6210 again, the claw 2100 cooperates with the cover 7100 to achieve the locking of the cover 7100.

[0091] For example, the rotating shaft 1220 drives the claw 2100 to rotate to unlock the cover body 7100. At the same time, the claw 2100 causes the second elastic member 5200 to elastically deform. After the cover body 7100 opens the delivery port 6210, the first elastic member 5100 releases elastic potential energy to drive the claw 2100 to move from the third position to the fourth position. The second elastic member 5200 releases elastic potential energy to drive the claw 2100 to reset in the opposite direction of the rotation direction of unlocking the cover body 7100.

[0092] Furthermore, in some embodiments, when the cover body 7100 switches from a state of opening the delivery port 6210 to a state of closing the delivery port 6210, the abutment portion 7110 of the cover body 7100 touches the locking portion 2120 of the claw 2100, so that the claw 2100 first rotates in the direction of unlocking the cover body 7100 and then rotates in the opposite direction to stop the abutment portion 7110 in the direction in which the cover body 7100 opens the delivery port 6210.

[0093] Specifically, when the cover body 7100 is switched to the state of closing the delivery port 6210, when the abutting portion 7110 and the locking portion 2120 touch each other, the improvement of the structures of the two is used so that the abutting portion 7110 generates a component force on the locking portion 2120, and the component force prompts the claw 2100 to rotate in the direction of unlocking the cover body 7100, thereby forming an avoidance of the abutting portion 7110. At this time, the second elastic member 5200 elastically deforms, and as the cover body 7100 moves into place (pushing the claw 2100 to switch from the fourth position to the third position), the second elastic member 5200 releases its elastic potential energy (i.e., restores the deformation), and the second elastic member 5200 generates a force on the claw 2100 so that the claw 2100 is reset in the opposite direction of the rotation direction of unlocking the cover body 7100. In this way, the abutting portion 7110 can be stopped in the direction in which the cover body 7100 opens the delivery port 6210, thereby maintaining the cover body 7100 in the state of closing the delivery port 6210.

[0094] Combination Fig.16 As shown, in some embodiments, the third actuator 3000 is suitable for being separated from the communication port 6310 of the dispensing device when active, so that the third detergent flows out from 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 the communication port 6310. The third actuator 3000 is used to be separated from and block the communication port 6310. When the third detergent is placed in the position, the third actuator 3000 needs to block the communication port 6310, and the third detergent cannot leave the third cavity 6300 and flow out from the communication port 6310. When the third actuator 3000 is separated from the communication port 6310, the third detergent can flow out from the communication port 6310, and then the dispensing of the third detergent is realized. In this embodiment, the third detergent is a liquid detergent such as a rinse aid. When the third detergent needs to be added, the output component 1200 drives the third actuator 3000 to move, so that the third actuator 3000 is separated from the connecting port 6310, and the third detergent flows out from the connecting port 6310, and then is added directly or indirectly.

[0095] Combination Fig.16As shown, in some embodiments, the output component 1200 includes a gear 1210, the gear 1210 is provided with a toothed portion 1212, and the third actuator 3000 is provided with a rack portion 3100. The gear 1210 is suitable for driving the third actuator 3000 to move through the meshing of the toothed portion 1212 and the rack portion 3100 when rotating. The gear 1210 is a part of the output component 1200, and the rotation of the output component 1200 realizes the rotation of the gear 1210. When the gear 1210 rotates, the toothed portion 1212 follows the rotation, and the toothed portion 1212 meshes with the rack portion 3100, so that the rotation of the gear 1210 can drive the rack portion 3100 to move, and the movement of the rack portion 3100 can cause the third actuator 3000 to disengage from the communication port 6310. By such a configuration, the linear displacement of the third actuator 3000 can be realized, and it can be more effectively disengaged from the communication port 6310.

[0096] Combination Fig.16 As shown, in some embodiments, the tooth portion 1212 is suitable for being separated from the rack portion 3100 after the third actuator 3000 is separated from the connecting port 6310, and the delivery device also includes a third elastic member 5300, which is suitable for generating force on the third actuator 3000 to drive the third actuator 3000 to move toward the connecting port 6310 to block the connecting port 6310 after the tooth portion 1212 and the rack portion 3100 are separated.

[0097] Specifically, the tooth portion 1212 is not arranged along the circumference of the entire gear 1210, but is arranged at a certain position on the circumference of the gear 1210, so that when the gear 1210 rotates, the tooth portion 1212 meshes with the rack portion 3100 and drives the third actuator 3000 to disengage from the connecting port 6310. When the gear 1210 continues to rotate a certain angle, the tooth portion 1212 separates from the rack portion 3100. In this embodiment, by providing the third elastic member 5300, the third elastic member 5300 generates a force on the third actuator 3000, that is, when the gear 1210 rotates and the tooth portion 1212 engages with the rack portion 3100, thereby driving the third actuator 3000 to disengage from the connecting port 6310, the third elastic member 5300 undergoes elastic deformation to accumulate elastic potential energy and generates a force on the third actuator 3000. When the gear 1210 continues to rotate a certain angle to separate the tooth portion 1212 from the rack portion 3100, the third elastic member 5300 releases the elastic potential energy, thereby driving the third actuator 3000 to move toward the connecting port 6310 and block the connecting port 6310. In this way, the connecting port 6310 can be blocked without changing the rotation direction of the gear 1210.

[0098] When the output component 1200 is suitable for driving the third actuator 3000 to move multiple times after driving the claw 2100 to switch to the fourth position, multiple injections of the third detergent can be achieved through multiple rotations of the gear 1210.

[0099] Combination Figures 1 to 16 As shown, in some embodiments, the power source 1100 is a motor, and the output component 1200 includes a rotating shaft 1220 and a gear 1210 sleeved on the rotating shaft 1220. The motor is suitable for driving the gear 1210 to rotate, and the gear 1210 is suitable for driving the rotating shaft 1220 to rotate. The motor can drive the gear 1210 to rotate directly or indirectly. The gear 1210 is sleeved on the rotating shaft 1220 and is fixed to each other. The two rotate coaxially, saving space, and have the same rotation direction. The rotating shaft 1220 is connected to the second actuator 2000 to drive the second actuator 2000 to move. The gear 1210 is provided with a tooth portion 1212 and a protrusion 1211 arranged along its axial direction. The gear 1210 is suitable for driving the third actuator 3000 to move through the tooth portion 1212, and is suitable for touching the trigger 4000 through the protrusion 1211. The cooperation between the rotating shaft 1220 and the second actuator 2000, the cooperation between the tooth portion 1212 and the third actuator 3000, and the cooperation between the protrusion 1211 and the trigger 4000 are recorded above.

[0100] Taking the application of the dispensing device to a washing appliance as an example for illustration, the second detergent is dishwashing powder or dishwashing tablets, and the third detergent is a rinse aid.

[0101] In the initial state (the state before the dispensing device is operated), the protrusion 1211 is in the first position 1222 .

[0102] When it is necessary to add the second detergent, the motor rotates along the first direction, and the motor drives the gear 1210 and the rotating shaft 1220 to rotate by an angle β, thereby driving the claw 2100 to rotate. The claw 2100 rotates to unlock the cover body 7100 to achieve the addition of the second detergent (at this time, the tooth portion 1212 has not yet rotated to engage with the rack portion 3100, so the third detergent is not added when the second detergent is added). At this time, the claw 2100 switches from the third position to the fourth position under the action of the first elastic member 5100, and the motor pauses for time T (that is, the gear 1210 and the rotating shaft 1220 also pause for time T).

[0103] After the motor stops rotating for time T, washing enters the next stage, and the motor continues to rotate in the first direction, thereby driving the gear 1210 and the rotating shaft 1220 to continue to rotate, so that the tooth portion 1212 engages with the rack portion 3100, thereby driving the third actuator 3000 to disengage from the connecting port 6310 (because the claw 2100 is in the fourth position, the rotating shaft 1220 no longer drives the claw 2100 to rotate), thereby realizing the first injection of the third detergent. As the gear 1210 and the rotating shaft 1220 continue to rotate, the tooth portion 1212 separates from the rack portion 3100, and the third elastic member 5300 resets the third actuator 3000 to block the connecting port 6310 until the protrusion 1211 rotates to touch the trigger 4000, and the motor stops rotating, thereby causing the gear 1210 and the rotating shaft 1220 to stop rotating, and the protrusion 1211 returns to the first position 1222.

[0104] After the first dispensing of the third detergent is completed and the protrusion returns to the first position 1222, the motor can be controlled to rotate in the first direction again, so that the protrusion 1211 rotates again until it returns to the first position 1222. This process realizes the second dispensing of the third detergent (because the claw 2100 is in the fourth position, the rotating shaft 1220 no longer drives the claw 2100 to rotate). This process is repeated and the number of times the third detergent is dispensed can be set according to actual needs.

[0105] After the dispensing device completes the dispensing work, the protrusion 1211 is located at the first position 1222. After the washing appliance finishes working, the user can refill the second detergent (the third detergent does not need to be refilled every time), and then switch the cover body 7100 to the state of closing the dispensing port 6210, push the claw 2100 to switch from the fourth position to the third position, and the protrusion 1221 is locked into the notch 2110.

[0106] The second aspect of the present application discloses a washing appliance, which includes the above-mentioned dispensing device. The washing appliance can be a dishwasher, a washing machine, or other types of washing appliances. It can be understood that the dispensing device 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.

All equivalent structural changes made based on the concept of the present application and the contents of the present application description and drawings, or direct / indirect application in other related technical fields are included in the patent protection scope of the present application.
