[0024] refer to Figure 1 As shown, this utility model provides a cleaning machine 10, which can be a baby bottle cleaner or a small dishwasher, small washing machine or other cleaning appliances.

[0025] For example, such as Figure 1 As shown, the cleaning machine 10 according to an embodiment of the present invention may include a cleaning body 11 and a feeding device 12. The cleaning body 11 provides a cleaning space and performs cleaning operations. The feeding device 12 automatically and quantitatively dispenses solid detergent into the cleaning space inside the cleaning body 11.

[0026] The following will describe in detail the specific embodiments of the feeding device 12 of this utility model with reference to the accompanying drawings.

[0027] Please see Figure 2 As shown, the feeding device 12 of this utility model embodiment can be arranged vertically as a whole so that the solid detergent can fall automatically under the action of gravity to achieve feeding.

[0028] like Figure 2 and Figure 3 As shown, the feeding device 12 includes a housing assembly 100, a pusher frame 200, a dispensing tray 300, a drive assembly 400, and a control assembly. The housing assembly 100 includes an overlapping material-holding chamber 110 and a dispensing chamber 120. The material-holding chamber 110 is used to hold solid detergent, and the dispensing chamber 120 is used to dispense the detergent. The material-holding chamber 110 has a feeding port 111, and the dispensing chamber 120 has a discharging port 121. The material-holding chamber 110 and the dispensing chamber 120 are connected through a discharge port 112.

[0029] See Figure 3 In one embodiment, the housing assembly 100 includes an upper housing 130 and a lower housing 140. The upper housing 130 may be configured as a hollow housing structure with an open top. The hollow portion of the upper housing 130 may form a holding cavity 110 for holding solid detergent. Optionally, the upper housing 130 may have a cylindrical or square columnar shape. The holding cavity 110 may have a circular shape to allow for the rotatable pusher 200.

[0030] See Figure 3 The top opening of the upper housing 130 is a feeding port 111 for adding solid detergent. Users can add multiple solid detergents at once through the feeding port 111 and store them in the holding chamber 110, so that the feeding device 12 can achieve the purpose of multiple uses with one feeding, thereby reducing the frequency of manual feeding and improving the ease of use of the feeding device 12.

[0031] See Figure 3 In one embodiment, the feeding device 12 further includes a capping assembly 600, which is closable and disposed at the feeding port 111 of the upper housing 130. The capping assembly 600 is used to seal the feeding port 111.

[0032] Optionally, the capping assembly 600 may include a cap 610 and a sealing ring 620. The cap 610 is detachably connected to the upper housing 130 to open or close the feeding port 111. The cap 610 may have a downwardly protruding connecting ring that inserts downward into the feeding port 111, thus connecting the cap 610 to the upper housing 130 and closing the feeding port 111. When it is necessary to add solid detergent into the upper housing 130, the cap 610 can be pulled upwards.

[0033] The sealing ring 620 can be fitted onto the connecting ring. When the cover 610 closes the feeding port 111, the connecting ring is inserted downwards into the feeding port 111, and the sealing ring 620 abuts against the inner circumferential side wall of the upper housing 130. Thus, the sealing ring 620 fills the gap between the connecting ring and the upper housing 130. The sealing ring 620 not only makes the connection between the cover 610 and the upper housing 130 tighter, but also provides a sealing and moisture-proof function, ensuring the cleanliness and effectiveness of the solid detergent.

[0034] In this embodiment, when it is necessary to add solid detergent into the upper housing 130, the cover 610 can be opened. At other times, the cover 610 can be closed to the feeding port 111, which is conducive to the long-term storage of solid detergent and prevents it from becoming ineffective.

[0035] It is understood that in other embodiments, the cover 610 and the upper housing 130 can also be connected by a rotating opening and closing mechanism. Additionally, a sealing ring structure can be provided at the connection point to ensure sealing and moisture-proof performance.

[0036] like Figure 3 As shown, a fixing part 131 may be provided on the outer peripheral side wall of the upper housing 130, and the fixing part 131 is used to connect and fix it to the cleaning body 11. Optionally, the fixing part 131 may include a connecting seat 132, and the connecting seat 132 may have a connecting hole. The cleaning body 11 may have a fixing hole corresponding to the connecting hole. Thus, the upper housing 130 and the cleaning body 11 are connected by screws passing through the connecting hole and the fixing hole, thereby realizing the connection between the feeding device 12 and the cleaning body 11.

[0037] refer to Figure 3 The fixing part 131 may also include a ring 133. The cleaning body 11 may be provided with a hook, and the hook part of the hook can be inserted into the ring 133. Thus, the upper housing 130 and the cleaning body 11 are connected by the cooperation of the ring 133 and the hook, thereby realizing the connection between the feeding device 12 and the cleaning body 11.

[0038] like Figure 3As shown, the bottom of the upper housing 130 is provided with a discharge port 112 for solid detergent to pass through. The discharge port 112 is used to connect to the dispensing chamber 120, so that the solid detergent can fall into the dispensing chamber 120. The discharge port 112 can be square or round, etc., to be suitable for passing one or a certain number of block-shaped solid detergents at a time, or passing a certain amount of granular detergents at a time, etc., and can be set according to actual needs.

[0039] See Figure 3 The top end of the lower housing 140 is connected to the bottom end of the upper housing 130. The lower housing 140 can be configured as a hollow housing structure with an open top. The hollow portion of the lower housing 140 can form a dispensing cavity 120 for dispensing materials. Optionally, the lower housing 140 can have a shape that matches the cross-section of the upper housing 130; for example, the lower housing 140 can be cylindrical or square-shaped. The dispensing cavity 120 can have a circular shape to allow for the rotatable dispensing disc 300.

[0040] Optionally, the upper housing 130 and the lower housing 140 can be connected by a screw structure: the outer peripheral sidewall at the bottom of the upper housing 130 can be provided with multiple connecting through holes 134, and the outer peripheral sidewall at the top of the lower housing 140 can be provided with multiple threaded holes 141 corresponding to the multiple connecting through holes 134. Screws can be passed through the connecting through holes 134 and the corresponding threaded holes 141 and tightened.

[0041] It is understood that in other embodiments, the upper housing 130 and the lower housing 140 may also adopt other structural forms such as snap-fit ​​connection or pin connection, which can be set according to needs.

[0042] It is understood that in other embodiments, the housing assembly 100 may also be a one-piece molded structure, with an internally overlapping material-holding cavity 110 and a material-distributing cavity 120. Alternatively, the housing assembly 100 may also be configured to include two housings connected front to back, which, when connected in the front-back direction, can enclose the overlapping material-holding cavity 110 and the material-distributing cavity 120. The specific configuration can be made according to actual needs.

[0043] See Figure 3 The interior of the lower housing 140, specifically the dispensing chamber 120, communicates with the dispensing port 112. The dispensing chamber 120 is used to install the dispensing tray 300. The dispensing port 121 is located at the bottom of the lower housing 140 and is used to allow solid detergent to pass through, thereby dispensing solid detergent into the cleaning body 11. The dispensing port 121 can be square or circular, etc., to accommodate one or a certain number of block-shaped solid detergents or a certain amount of granular detergents passing through at one time, depending on actual needs.

[0044] Optionally, the discharge port 112 and the outlet 121 are staggered in the vertical direction. That is, the projections of the discharge port 112 and the outlet 121 on the same horizontal plane do not coincide. For example Figure 3 As illustrated, the discharge port 112 and the outlet 121 can be arranged at approximately a 180° angle. In this embodiment, by staggering the discharge port 112 and the outlet 121 in the vertical direction, the solid detergent can only be distributed and discharged through the distribution tray 300, and cannot directly reach the outlet 121 from the discharge port 112. Therefore, it is beneficial to achieve quantitative dispensing of solid detergent.

[0045] See Figure 3 In this embodiment of the invention, the pusher 200 is rotatably disposed in the material-holding cavity 110 within the upper housing 130. The pusher 200 is mainly used to push the solid detergent within the upper housing 130 into the discharge port 112. By using the pusher 200 to push the solid detergent, the solid detergent can fall smoothly into the discharge port 112, avoiding jamming, thereby improving the reliability of the feeding device 12.

[0046] Optionally, the pusher frame 200 may include a pusher body 210 and a plurality of push rods 220 disposed on the outer periphery of the pusher body 210. The plurality of push rods 220 are arranged at intervals and can divide the material receiving cavity 110 into several independent spaces. For example, such as Figure 3 As shown, the outer periphery of the pusher body 210 may be provided with three push rods 220, which can divide the material holding chamber 110 into three independent spaces. During the rotation of the pusher frame 200, each push rod 220 can play a stirring and pushing role respectively, so that the solid detergent can fall smoothly into the discharge port 112, and prevent the solid detergent from piling up and becoming difficult to push.

[0047] like Figure 3 As shown, the outer edge dimension of the pusher 200 can match the inner circumferential surface dimension of the hollow cavity of the upper housing 130. That is, while ensuring that the pusher 200 can rotate freely, there is only a small gap between the two to minimize the possibility of solid detergent getting stuck between the outer periphery of the pusher 200 and the inner circumferential surface of the upper housing 130. Optionally, the discharge port 112 can be opened at the edge of the bottom of the upper housing 130. Under the pushing action of the push rod 220, the solid detergent can be dispersed radially along the upper housing 130 and fall smoothly into the discharge port 112.

[0048] See Figure 3As shown, optionally, the push rod 220 can be plate-shaped. The end of the push rod 220 away from the pusher body 210 is wedge-shaped, that is, the end of the push rod 220 near the pusher body 210 is wider, and the end away from the pusher body 210 is narrower, and the end of the push rod 220 away from the pusher body 210 is arc-shaped. With this configuration, during the rotation of the pusher frame 200, each push rod 220 can use the rotational vibration force of the drive assembly 400 to disperse the piled solid detergent, ensuring that the solid detergent at the edge is dispersed and falls into the discharge port 112.

[0049] like Figure 3 As shown, because the end of the push rod 220 away from the pusher body 210 is wedge-shaped, part of the bottom surface of the push rod 220 forms an inclined surface sloping downwards towards the pusher body 210. Furthermore, the shape of the cavity wall opposite the bottom surface of the material receiving cavity 110 and the push rod 220 is adapted to match the push rod 220; that is, the cavity wall opposite the bottom surface of the material receiving cavity 110 and the push rod 220 is also partially inclined. In addition, there is a certain gap between the material receiving cavity 110 and the push rod 220. During the rotation of the pusher frame 200, because the shape of the bottom surface of the push rod 220 matches the cavity wall of the material receiving cavity 110 and there is a certain gap, the push rod 220 allows solid detergent entering the discharge port 112 to pass through, preventing the solid detergent from flowing away empty; at the same time, the push rod 220 can also scrape away excess solid detergent above the discharge port 112, preventing overfeeding and thus improving the feeding accuracy.

[0050] See Figure 3 In this embodiment of the invention, the dispensing disc 300 is rotatably disposed in the dispensing cavity 120 within the lower housing 140. The outer edge dimension of the dispensing disc 300 can match the inner circumferential surface dimension of the hollow cavity of the lower housing 140. That is, while ensuring the dispensing disc 300 can rotate freely, there is only a small gap between them to minimize the possibility of solid detergent getting stuck between the outer periphery of the dispensing disc 300 and the inner circumferential surface of the lower housing 140.

[0051] like Figure 3 As shown, the material distribution plate 300 is provided with a material distribution groove 310. During the rotation of the material distribution plate 300, the material distribution plate 300 has a feeding state in which the material distribution groove 310 is in relative communication with the discharge port 112, and a discharging state in which the material distribution groove 310 is in relative communication with the discharge port 121.

[0052] The dispensing tank 310 can be square or round, etc., to accommodate one or a certain number of block-shaped solid detergents at a time, or to accommodate a certain amount of granular detergents at a time, etc., and can be set according to actual needs.

[0053] Optionally, the material distribution trough 310 can be located at the edge of the material distribution plate 300. Correspondingly, the discharge port 121 can be located at the edge of the bottom of the lower housing 140.

[0054] Optionally, there may be two or more material distribution troughs 310, which are arranged circumferentially at intervals along the edge of the material distribution plate 300. For example, such as Figure 3 As shown, three distribution grooves 310 can be evenly arranged at the edge of the distribution plate 300. During the rotation of the distribution plate 300, any one of the distribution grooves 310 can be connected to the discharge port 112 or the outlet 121.

[0055] In this embodiment, any one of the dispensing troughs 310 can be rotated to a position communicating with the discharge port 112 to receive solid detergent falling through the discharge port 112. Then, the solid detergent rotates with the dispensing disc 300 to a position communicating with the discharge port 121, allowing it to be dispensed into the cleaning body 11 via the discharge port 121. Therefore, by rotating the dispensing disc 300 and coordinating the dispensing troughs 310 with the discharge port 112 or discharge port 121, quantitative dispensing of solid detergent can be achieved, enabling the dispensing device 12 to accurately and quantitatively dispense solid detergent, thus improving the accuracy of each dispensing operation.

[0056] See Figure 2 In an embodiment of this utility model, the drive assembly 400 extends at least partially into the housing assembly 100. The drive end of the drive assembly 400 is connected to the pusher 200 and the dispensing plate 300 to drive the pusher 200 and the dispensing plate 300 to rotate.

[0057] Optionally, the drive assembly 400 may include a drive element 410 and a rotating shaft 420. The drive element 410 serves as the power source for the drive assembly 400 and may be a motor that converts electrical energy into rotational motion of the rotating shaft 420. Optionally, the drive element 410 may be a stepper motor or a servo motor.

[0058] Optionally, such as Figure 3 As shown, the drive assembly 400 may further include a drive bracket 430, on which the drive component 410 is mounted. The drive bracket 430 may be detachably fixed to the cleaning body 11 by means of screws or other methods, depending on the specific circumstances.

[0059] See Figure 3 and Figure 4 The rotating shaft 420 serves as the drive end of the drive assembly 400, and is used to connect with the pusher frame 200 and the dispensing plate 300. The drive component 410 can drive the rotating shaft 420 to rotate, thereby causing the pusher frame 200 and the dispensing plate 300 to rotate.

[0060] Optionally, the rotating shaft 420 includes a first connecting shaft 423 and a second connecting shaft 424 connected together. The bottom end of the first connecting shaft 423 is connected to the driving member 410, and the top end of the first connecting shaft 423 extends upward through the lower housing 140 and is connected to the distributing plate 300. The bottom end of the first connecting shaft 423 can be connected to the driving member 410, such as the motor shaft of a motor, via a shaft hole fitting.

[0061] like Figure 3 As shown, the connection between the first connecting shaft 423 and the distributing disk 300 can be as follows: the top of the first connecting shaft 423 can be configured as a hollow shaft structure with an open top, and several through grooves 425 can be formed on the peripheral wall of the top of the first connecting shaft 423. Correspondingly, several snap-fit ​​holes 320 can be provided in the middle of the distributing disk 300. When the top of the first connecting shaft 423 is inserted upward into the lower housing 140, the peripheral wall portion of the top of the first connecting shaft 423 located between the two through grooves 425 can be inserted into the snap-fit ​​holes 320 of the distributing disk 300. Thus, the connection between the first connecting shaft 423 and the distributing disk 300 can be realized, and the distributing disk 300 can be driven to rotate.

[0062] like Figure 3 As shown, the bottom end of the second connecting shaft 424 is connected to the first connecting shaft 423, and the top of the second connecting shaft 424 extends upward through the upper housing 130 and is connected to the pusher frame 200. Optionally, the second connecting shaft 424 and the first connecting shaft 423 can be integrally formed and connected. The second connecting shaft 424 can be generally a cylindrical structure, with a cross-sectional dimension smaller than that of the hollow portion at the top of the first connecting shaft 423, and the second connecting shaft 424 can be disposed within the hollow portion at the top of the first connecting shaft 423.

[0063] like Figure 4 As shown, the connection between the second connecting shaft 424 and the pusher frame 200 can be achieved by providing several retaining ribs 426 on the circumferential surface of the second connecting shaft 424, each retaining rib 426 extending axially along the second connecting shaft 424. Correspondingly, the bottom of the pusher body 210 of the pusher frame 200 is provided with an insertion hole for the top end of the second connecting shaft 424 to be inserted, and several slots 230 are provided along the circumferential edge of the insertion hole. When the top end of the second connecting shaft 424 is inserted upwards into the upper housing 130, the top end of the second connecting shaft 424 can be inserted into the insertion hole, and the retaining ribs 426 can be inserted into the slots 230. This enables the connection between the second connecting shaft 424 and the pusher frame 200, and allows the pusher frame 200 to rotate.

[0064] Optionally, refer to Figure 3As shown, connecting screw holes can be provided at the top end of the first connecting shaft 423 and the top end of the pusher body 210, so as to use screws to axially limit and fix the pusher frame 200, the distributing plate 300 and the rotating shaft 420, and ensure the reliable use of the feeding device 12.

[0065] See Figure 2 In this embodiment of the invention, the control component is electrically connected to the drive component 400, and the control component is configured to control the drive component 400 to start or stop based on the rotation angle of the drive end of the drive component 400. Specifically, the control component can detect the rotation angle of the rotating shaft 420 and control the drive component 410 to start or stop based on the rotation angle of the rotating shaft 420.

[0066] like Figure 3 As shown, in one embodiment, the drive end of the drive assembly 400, i.e., the rotating shaft 420, is provided with a trigger part 421 corresponding to the material distribution groove 310. The control assembly includes a control element and a detection element 500, which are electrically connected. The detection element 500 can detect the rotation angle of the trigger part 421, and the control element can control the start or stop of the drive assembly 410 according to the rotation angle of the trigger part 421.

[0067] Optionally, the detection element 500 can be a photoelectric switch, a tactile switch, or a distance detection sensor, which can detect the position of the trigger part 421. Thus, when the trigger part 421 rotates with the rotating shaft 420, the detection element 500 can detect the rotation angle of the trigger part 421.

[0068] like Figure 3 As shown, in one embodiment, the detection element 500 includes a photoelectric switch 510, which includes a transmitter and a receiver. The photoelectric switch 510 can be a U-shaped slot photoelectric switch 510, with its transmitter and receiver located on opposite sides of the U-shaped slot.

[0069] Optionally, the detection component 500 also includes a switch bracket 520, which can be connected to the bottom of the lower housing 140 using a screw structure or similar method. The photoelectric switch 510 is fixedly mounted on the switch bracket 520.

[0070] Optionally, the control component can be a control chip, which can be shared with the main chip of the washing machine 10. The control chip can control the opening and closing of the drive component 410 based on the detection signal emitted by the detection component 500, such as the photoelectric switch 510, thereby realizing automatic feeding.

[0071] refer to Figure 3As shown, the trigger part 421 is disposed on the rotating shaft 420, and the trigger part 421 can rotate with the rotating shaft 420. When the trigger part 421 rotates to the position between the transmitter and the receiver, the trigger part 421 can block or allow the light beam emitted by the transmitter to reach the receiver, so that the photoelectric switch 510 can send a detection signal to the control chip, thereby controlling the drive unit 410 to stop, so that the dispensing plate 300 is kept in the dispensing state in which the dispensing groove 310 and the discharge port 121 are in relative communication.

[0072] In this embodiment, the triggering unit 421 can trigger the photoelectric switch 510 by either blocking the light beam or allowing the light beam to pass through. When the photoelectric switch 510 is triggered, it sends a detection signal to the control chip, which then controls the drive unit 410 to stop, keeping the dispensing tray 300 in the discharging state. At this time, the feeding device can complete one feeding cycle. Thus, through the cooperation of the photoelectric switch 510 and the triggering unit 421, automatic and controllable feeding of the feeding device 12 can be achieved, improving the automation level of the feeding device 12.

[0073] Optionally, such as Figure 3 As shown, the trigger part 421 can be structured as follows: a blocking disk 422 is provided on the driving end of the driving assembly 400, that is, on the rotating shaft 420, and the trigger part 421 is a through slot formed on the blocking disk 422. The through slot allows the light beam to pass through. When the blocking disk 422 rotates with the rotating shaft 420, allowing the light beam emitted by the transmitter to pass through the through slot and reach the receiver, the photoelectric switch 510 is triggered and can send a detection signal to the control chip to control the driving component 410 to stop, keeping the dispensing disk 300 in the discharging state.

[0074] In this embodiment, the detection element 500 includes a photoelectric switch 510, and the triggering part 421 is a through slot. The through slot can trigger the photoelectric switch 510 in a manner that allows a light beam to pass through, enabling the photoelectric switch 510 to detect the position of the through slot, thereby realizing the detection of the rotation angle of the rotating shaft 420. When the photoelectric switch 510 is triggered, it can send a detection signal to the control chip, controlling the drive element 410 to stop, keeping the dispensing plate 300 in the discharging state. At this time, the feeding device 12 completes one feeding cycle.

[0075] like Figure 3 As shown, optionally, the number and arrangement of the through slots correspond one-to-one with the material distribution slots 310. For example, when the material distribution plate 300 has three material distribution slots 310, there are also three through slots, and the three through slots correspond one-to-one with the three material distribution slots 310 in the vertical direction. Therefore, every time the shielding plate 422 rotates one-third of a revolution, the photoelectric switch 510 is triggered once, and the feeding device 12 can complete one feeding, which is conducive to achieving more precise and efficient feeding operations.

[0076] It is understood that in other embodiments, the trigger 421 is a through slot provided on the shielding plate 422, and the detection element 500 can be an infrared ranging sensor. The infrared ranging sensor measures distance by emitting infrared light and detecting reflected light; therefore, the distance measured by the infrared ranging sensor is larger at the through slot. Thus, the infrared ranging sensor can detect the position of the through slot, thereby realizing the detection of the rotation angle of the rotating shaft 420.

[0077] It is understood that in other embodiments, the trigger 421 may also be a baffle perpendicularly disposed on the outer periphery of the rotation shaft 420, and the detection element 500 may be a photoelectric switch 510. When the baffle rotates with the rotation shaft 420 to a position blocking the transmitter and receiver, the baffle can block the light beam from reaching the receiver, thereby triggering the photoelectric switch 510.

[0078] In this embodiment of the invention, the detection element 500 includes a photoelectric switch 510, which cooperates with a through slot provided in the shielding plate 422 to achieve precise and controllable feeding operation. However, the invention is not limited to this, and can be configured according to actual needs. For example, in other embodiments, the detection element 500 may include a tactile switch, which cooperates with a trigger part 421 on the rotating shaft 420, such as a touch plate. When the trigger part 421 rotates to the position of contacting the tactile switch, the tactile switch is triggered and can send a detection signal to the control element to control the drive element 410 to stop, so that the dispensing plate 300 remains in the discharging state.

[0079] See Figure 2 In one embodiment, the feeding device 12 further includes a discharge box 700, which is arranged below the housing assembly 100. For example, the discharge box 700 may be located on the lower side of the lower housing 140. The discharge box 700 may be detachably fixed to the cleaning body 11 by means of screws or other means, and is located on the lower side of the lower housing 140.

[0080] like Figure 3 As shown, the discharge box 700 can be a hollow cylindrical structure, with a discharge port 710 at its top opposite to the discharge port 121, and an opening at its bottom for connecting to the cleaning body 11. Thus, solid detergent falling through the discharge port 121 can be guided into the cleaning space within the cleaning body 11 by the discharge box 700, which facilitates the flexible arrangement of the feeding device 12.

[0081] refer to Figure 3 As shown, the material receiving box 700 can be a split structure, which may include a front box and a rear box, and the front box and the rear box can be connected by a snap-fit ​​connection. Alternatively, in other embodiments, the material receiving box 700 can also be a one-piece structure.

[0082] In use, the feeding device 12 of this embodiment works as follows: Following the cleaning program set by the cleaning machine 10, the drive unit 410 is activated. The drive unit 410 drives the rotating shaft 420 to rotate, which in turn drives the pusher frame 200 in the upper housing 130 and the dispensing tray 300 in the lower housing 140 to rotate together. Under the push of the pusher frame 200, solid detergent falls through the discharge port 112 into the lower housing 140 and enters the dispensing trough 310 of the dispensing tray 300. Then, the rotation of the dispensing tray 300 causes the solid detergent in the dispensing trough 310 to rotate. When a dispensing trough 310 rotates to a position where it is connected to the discharge port 121, the beam emitted by the transmitter of the photoelectric switch 510 passes through the corresponding slot below the dispensing trough 310 to reach the receiver. The photoelectric switch 510 is then triggered and can control the drive unit 410 to stop, keeping the dispensing tray 300 in the position where the dispensing trough 310 is connected to the discharge port 121. At this time, the solid detergent in the dispensing tank 310 can fall into the discharge port 121 and then into the cleaning body 11 through the discharge box 700. In this way, the feeding device 12 can achieve automatic and quantitative feeding in one operation.

[0083] The feeding device of this utility model embodiment has a material holding chamber that can be used to store solid detergent, enabling the feeding device to achieve multiple uses from a single feeding, thereby reducing the frequency of manual feeding and improving the ease of use of the feeding device. By setting a pusher to push the solid detergent, it can be smoothly dropped into the discharge port, avoiding jamming and thus improving the reliability of the feeding device. By setting a dispensing tray with dispensing grooves that can communicate and cooperate with the discharge port or outlet, quantitative dispensing of solid detergent can be achieved, enabling the feeding device to accurately and quantitatively dispense solid detergent, improving the accuracy of single dispensing. By setting a control component to control the start and stop of the drive component according to the rotation angle of the drive end, the feeding device can achieve automatic and controllable feeding, improving the automation level of the feeding device.

[0084] The above embodiments are merely illustrative examples of structures. The structures in each embodiment are not fixed combinations. In the absence of structural conflicts, the structures in multiple embodiments can be arbitrarily combined and used.
