Description

Technical Field

[0001] The present invention belongs to the field of clothing processing equipment, and in particular, relates to a feeding device and clothing processing equipment. Background Art

[0002] As users' demands for clothing treatment become increasingly diverse, different types of clothing treatment agents may need to be added during the operation of clothing treatment equipment. In order to simplify the user's operation process and improve the automation of clothing treatment equipment, existing clothing treatment equipment often has a function of automatically adding clothing treatment agents.

[0003] However, the automatic dispensing devices currently used in clothing treatment equipment often need to provide corresponding power sources, such as dispensing pumps, for each type of clothing treatment equipment in order to dispense different types of clothing treatment agents, so as to dispense different types of clothing treatment agents separately.

[0004] The above solution requires different delivery pumps to be controlled separately, which makes the delivery control process more complicated, and also causes high production costs. At the same time, setting two or more delivery pumps will inevitably take up a large space, resulting in a large installation space for the automatic delivery device, which is not conducive to the miniaturization of the entire clothing processing equipment.

[0005] In view of this, the present invention is proposed. Summary of the invention

[0006] The technical problem to be solved by the present invention is to overcome the deficiencies of the prior art and provide a dispensing device and a clothing processing device, which can drive a driving shaft to rotate forward and reversely through a power source to achieve control of selecting one of the two dispensing units for dispensing.

[0007] In order to solve the above technical problems, the basic concept of the technical solution adopted by the present invention is:

[0008] A delivery device, comprising:

[0009] A first delivery unit, comprising a first clutch mechanism;

[0010] A second delivery unit is stacked with the first delivery unit and includes a second clutch mechanism, wherein the clutch state of the second clutch mechanism is opposite to that of the first clutch mechanism;

[0011] A drive shaft, drivingly connected to the first clutch mechanism and the second clutch mechanism respectively;

[0012] The first clutch mechanism comprises:

[0013] The transmission wheel has a central hole, and a stop protrusion is arranged on the side wall of the central hole;

[0014] A connecting member, disposed in the central hole and connected to the driving shaft and rotating therewith;

[0015] A claw, disposed in the central hole and hinged to the connecting member;

[0016] The driving shaft drives the connecting member to rotate in a first direction, the claw stops against the stop protrusion, and drives the transmission wheel to rotate synchronously, thereby controlling the first delivery unit to deliver; the driving shaft drives the connecting member to rotate in a second direction opposite to the first direction, the claw separates from the stop protrusion, and the first delivery unit does not deliver.

[0017] Furthermore, the stop protrusion has a stop surface and a sliding surface which are at a certain angle, and the stop surface and the sliding surface are parallel to the rotation axis of the transmission wheel;

[0018] The drive shaft drives the connecting member to rotate in a first direction, and the claw stops at the stop surface, pushing the transmission wheel to rotate synchronously; the drive shaft drives the connecting member to rotate in a second direction, and the claw can slide along the sliding surface and separate from the stop surface, and the transmission wheel remains stationary.

[0019] Furthermore, the stop surface is arranged along the radial direction of the transmission wheel, and the sliding surface and the stop surface are perpendicular to each other.

[0020] Furthermore, the stop protrusions are provided in plurality and are spaced apart along the circumference of the transmission wheel; among two adjacent stop protrusions, the stop surface of one stop protrusion is connected to the sliding surface of the other stop protrusion through the arc-shaped extending side wall of the center hole.

[0021] Furthermore, one side surface of the transmission wheel is partially concave to form an inner groove, and the inner groove constitutes the central hole; the connecting piece and the claw are arranged in the inner groove and are not higher than the surface of the transmission wheel located outside the inner groove.

[0022] Furthermore, the clamping claw and / or the connecting member has a limiting structure for limiting the relative rotation angle range between the clamping claw and the connecting member.

[0023] Further, the connecting member is a flat plate-like structure; the claw comprises a hinge part and a push part with different thicknesses, and the thickness of the push part is greater than the thickness of the hinge part; the limiting structure is a limiting surface formed at the connection between the push part and the hinge part and perpendicular to the flat plate-like structure;

[0024] The hinged portion and the flat plate-like structure are at least partially overlapped and are hingedly connected in the overlapping area; the pushing portion is located outside the covering area of ​​the flat plate-like structure, and during the rotation of the claw relative to the connecting piece, the limiting surface and the outer periphery of the flat plate-like structure are stopped and limited.

[0025] Furthermore, the second clutch mechanism has the same structure as the first clutch mechanism.

[0026] Furthermore, it also includes a first shell, a second shell and a cover body connected in sequence;

[0027] One side of the second shell is open, and the cover body is snapped onto the open portion of the second shell to form a delivery cavity of the second delivery unit; one side of the first shell is open, and the side of the second shell opposite to its own open portion is snapped onto the open portion of the first shell to form a delivery cavity of the first delivery unit.

[0028] A clothes treating device comprises the above-mentioned clothes treating agent delivery device.

[0029] After adopting the above technical scheme, the present invention has the following beneficial effects compared with the prior art.

[0030] In the present invention, when the driving shaft rotates forward or reversely, one of the first and second clutch mechanisms can be controlled to be in an engaged state and the other can be controlled to be in a disengaged state, so that the first and second delivery units can be controlled to selectively deliver one of them, thereby achieving the purpose of using one power source to control the two delivery units to selectively deliver one of them, simplifying the control and reducing the cost.

[0031] In the present invention, the first clutch mechanism includes a transmission wheel with a stop protrusion on the side wall of the center hole, a connecting piece connected to the driving shaft, and a claw that can achieve clutch cooperation with the stop protrusion. The stop protrusion has a stop surface that is matched with the claw and is arranged along the radial direction of the transmission wheel, which makes it easier to achieve a stable pushing effect of the claw on the transmission wheel.

[0032] In the present invention, the relative rotation angle range between the claw and the connecting member is limited by the limiting structure, especially when the first clutch mechanism is in a disengaged state, so that the claw can be prevented from rotating too much, and then when the drive shaft reverses and rotates, the claw cannot be reset, resulting in the failure of the first clutch mechanism. The limiting structure is formed by the thickness change of the claw itself, which is simple and effective.

[0033] The specific implementation modes of the present invention are further described in detail below in conjunction with the accompanying drawings. BRIEF DESCRIPTION OF THE DRAWINGS

[0045] In order to make the purpose, technical solutions and advantages of the embodiments of the present invention clearer, the technical solutions in the embodiments will be clearly and completely described below in conjunction with the drawings in the embodiments of the present invention. The following embodiments are used to illustrate the present invention but are not used to limit the scope of the present invention.

[0048] Embodiment 1

[0049] like Figures 1 to 8As shown, this embodiment provides a dispensing device and a clothing treatment device having the dispensing device. The clothing treatment device can be a pulsator washing machine, a drum washing machine, a washer-dryer, etc., and the dispensing device can be used to dispense clothing treatment agents such as detergents and softeners.

[0050] In this embodiment, the dispensing device includes a first dispensing unit 1 and a second dispensing unit 2, both of which can be used to dispense different types of clothing treatment agents, so that the clothing treatment device has at least two automatic dispensing functions for clothing treatment agents. For example, the dispensing device dispenses detergent through the first dispensing unit 1 and dispenses softener through the second dispensing unit 2. When the clothing treatment device runs a laundry program, the first dispensing unit 1 is controlled to perform a dispensing operation in the washing stage, and the second dispensing unit 2 is controlled to perform a dispensing operation in the rinsing stage, so that dispensing can be performed separately for different operation stages of the laundry program.

[0051] Specifically, the first delivery unit 1 and the second delivery unit 2 are stacked up and down, wherein the first delivery unit 1 includes a first clutch mechanism, and the second delivery unit 2 includes a second clutch mechanism, and the clutch state of the second clutch mechanism is opposite to the clutch state of the first clutch mechanism. The delivery device also includes a drive shaft 200, which is transmission-connected to the first delivery unit 1 through the first clutch mechanism and transmission-connected to the second delivery unit 2 through the second clutch mechanism.

[0052] It can be understood that the above-mentioned clutch state means oppositely that: when the first clutch mechanism is in the engaged state, that is, the drive shaft 200 can transmit torque through the first clutch mechanism, the second clutch state is in the disengaged state, that is, the drive shaft 200 cannot transmit torque through the second clutch mechanism, and vice versa.

[0053] Furthermore, the dispensing device of this embodiment also includes a power unit 3, which is connected to the drive shaft 200, and the drive shaft 200 can rotate under the driving action of the power unit 3. The dispensing device has the above structure, which enables the same power unit 3 to drive the drive shaft 200 to rotate forward and reverse, that is, to transmit torque to one of the first dispensing unit 1 and the second dispensing unit 2, and then control the two to perform the dispensing operation. Compared with the method in the prior art that requires multiple dispensing pumps to control the dispensing of different types of clothing treatment agents respectively, the solution of this embodiment reduces the number of drive devices set, the control is simpler, and it helps to reduce costs.

[0054] In this embodiment, the specific structure of the first clutch mechanism is shown in Figures 2 to 5Specifically, the first clutch mechanism includes a transmission wheel 410 having a center hole, and a connecting member 420 and a claw 430 disposed in the center hole. A stop protrusion 412 is disposed on the side wall of the center hole, the connecting member 420 is connected to the drive shaft 200 and rotates therewith, and the claw 430 is hinged to the connecting member 420, so that the connecting member 420 and the claw 430 can rotate relative to each other.

[0055] During the operation of the delivery device, if the drive shaft 200 drives the connecting member 420 in the first direction (i.e. Figure 2 ), the claw 430 can stop against the stop protrusion 412, thereby driving the transmission wheel 410 to rotate synchronously, and at this time, the first dispensing unit 1 is controlled to dispense the laundry treatment agent. Figure 4 If the first dispensing unit 1 is rotated clockwise (as shown in FIG. 1 ), the claw 430 will be separated from the stop protrusion 412, and the first dispensing unit 1 will not perform dispensing.

[0056] Specifically, the stop protrusion 412 described in this embodiment has a stop surface 413 and a sliding surface 414 at a certain angle, and the stop surface 413 and the sliding surface 414 are parallel to the rotation axis of the transmission wheel 410. When the driving shaft 200 drives the connecting member 420 to rotate counterclockwise, the claw 430 stops at the stop surface 413, thereby pushing the transmission wheel 410 to rotate synchronously, and controlling the first delivery unit 1 to deliver. When the driving shaft 200 drives the connecting member 420 to rotate clockwise, the claw 430 can swing a certain angle relative to the connecting member 420, so that the claw 430 can slide along the sliding surface 414 and separate from the stop surface 413, and at this time the transmission wheel 410 can remain stationary, so that the first delivery unit 1 does not deliver.

[0057] Furthermore, an elastic member, such as a torsion spring, is provided between the claw 430 and the connecting member 420. The elastic force of the elastic member is used to keep the claw 430 and the connecting member 420 in a closed position. Figure 2 The relative position relationship shown in the figure. When the connecting member 420 rotates clockwise, the claw 430 swings counterclockwise relative to the connecting member 420 and contracts, so that the first clutch mechanism is in a disengaged state. After the connecting member 420 stops rotating, the claw 430 can automatically reset under the action of the elastic member. When the connecting member 420 rotates counterclockwise again, the claw 430 can stop against the stop surface 413, thereby driving the transmission wheel 410 to rotate synchronously.

[0058] As a preferred solution of this embodiment, the stop surface 413 is arranged along the radial direction of the transmission wheel 410 , and the sliding surface 414 and the stop surface 413 are perpendicular to each other.

[0059] Specifically, the central hole is a circular hole coaxial with the transmission wheel 410, and the stop surface 413 is arranged along the radial direction of the transmission wheel 410, that is, the stop surface 413 is perpendicular to the tangent direction of the side wall of the central hole, and thus the driving force of the claw 430 on the stop protrusion 412 is close to or coincides with the tangent direction of the side wall of the central hole. In this way, it is easier to achieve a stable driving effect of the claw 430 on the transmission wheel 410, and the torque output by the power unit 3 to the drive shaft 200 can be reduced.

[0060] In a further solution of this embodiment, a plurality of stop protrusions 412 are provided and spaced apart along the circumference of the transmission wheel 410. Of two adjacent stop protrusions 412, the stop surface 413 of one stop protrusion 412 is connected to the sliding surface 414 of the other stop protrusion 412 through the arc-shaped central hole side wall.

[0061] With the above structure, when the driving direction of the driving shaft 200 is switched from counterclockwise to clockwise, the claw 430 first slides a certain distance along the arc-shaped side wall of the center hole, and then slides along the sliding surface 414. At this time, the claw 430 begins to rotate and gradually shrink relative to the connecting member 420. The side wall of the center hole plays a role of buffering transition, effectively preventing the claw 430 from getting stuck when the clutch state is switched.

[0062] In the detailed scheme of this embodiment, a joint shaft 431 is provided at one end of the claw 430, and a hinged connection with the connecting member 420 is realized through the joint shaft 431. The other end area of ​​the claw 430 away from the joint shaft 431 is used to cooperate with the stop protrusion 412 for transmission. When the first clutch mechanism is in the engaged state, the side surface of the claw 430 close to the end contacts and stops with the stop surface 413. The end of the claw 430 away from the joint shaft 431 is a rounded structure. When the first clutch mechanism is in the disengaged state, the rounded structure at the end of the claw 430 slides along the side wall of the center hole and the sliding surface 414, effectively reducing the resistance caused by sliding friction.

[0063] In a further solution of this embodiment, one side surface of the transmission wheel 410 is partially concave to form an inner groove 411, and the inner groove 411 constitutes the central hole. The connecting piece 420 and the claw 430 are arranged in the inner groove 411 and are not higher than the surface of the transmission wheel 410 located outside the inner groove 411.

[0064] Specifically, the first delivery unit 1 has a delivery cavity, and the first clutch mechanism is arranged in the delivery cavity. With the above structure, the overall structure composed of the transmission wheel 410, the connecting member 420 and the claw 430 can be as compact as possible, reducing the required installation space, which is conducive to realizing the miniaturization design of the delivery device.

[0065] In this embodiment, further, the claw 430 has a limiting structure for limiting the relative rotation angle range between the claw 430 and the connecting member 420 .

[0066] During the operation of the delivery device, when the drive shaft 200 rotates clockwise, the swing angle of the claw 430 relative to the connecting member 420 only needs to ensure that the end of the claw 430 can pass over the connecting position of the stop surface 413 and the sliding surface 414 on the stop protrusion 412. However, if the rotation speed of the drive shaft 200 is high, the claw 430 may further rotate and shrink under the action of inertia. At this time, there is a risk that the swing angle of the claw 430 is too large and exceeds the elastic deformation range of the elastic member, which may cause the claw 430 to be unable to rotate and reset.

[0067] By providing the above-mentioned limiting structure on the claw 430, the above-mentioned problem can be effectively avoided, ensuring that the claw 430 always rotates relative to the connecting member 420 within the angle range that can be automatically reset, thereby ensuring the reliability of the first clutch mechanism.

[0068] It is understandable that the limiting structure may also be provided on the connecting member, which can also prevent the problem of excessive rotation of the claw and inability to reset.

[0069] As a specific solution of this embodiment, the connecting member 420 is a flat plate structure. The claw 430 includes a hinge portion 432 and a push portion 433 with different thicknesses, wherein the thickness of the push portion 433 is greater than the thickness of the hinge portion 432. The claw 430 adopts the above structure, and a limiting surface 434 perpendicular to the flat plate structure connecting member 420 is formed at the connection between the push portion 433 and the hinge portion 432, which can serve as the limiting structure.

[0070] The hinged portion 432 of the claw 430 is at least partially overlapped with the flat-plate structure connecting member 420, and is hingedly connected in the overlapping area. The pushing portion 433 is located outside the coverage area of ​​the flat-plate structure connecting member 420. During the rotation of the claw 430 relative to the connecting member 420, the limiting surface 434 is stopped and limited by the outer periphery of the flat-plate structure.

[0071] More specifically, a protruding columnar joint shaft 431 is provided on the upper surface of the hinge portion 432, and a hinge hole is provided at a corresponding position of the connector 420, and the joint shaft 431 is rotatably inserted into the hinge hole, so that the claw 430 and the connector 420 can rotate relative to each other. The limiting surface 434 is also located on the upper side of the hinge portion 432 like the joint shaft 431, and when the claw 430 rotates counterclockwise relative to the connector 420 to the limit position, one end of the limiting surface 434 stops at the outer peripheral side of the flat structure, thereby achieving a limiting effect.

[0072] When the delivery device of this embodiment is working, the driving shaft 200 can be driven by the power unit 3 to rotate at high speed. When the first clutch mechanism is in a disengaged state, the claw 430 can remain contracted under inertia, thereby completely disengaging from the stop protrusion 412, thereby avoiding abnormal noise during operation.

[0073] In a specific implementation of this embodiment, Figure 2 As shown, two claws 430 are symmetrically arranged on the connecting member 420 relative to the driving shaft 200. More specifically, the connecting member 420 is approximately a rhombus-shaped flat plate, and the claws 430 are arranged at both ends of the longer diagonal line of the rhombus.

[0074] In this embodiment, the second clutch mechanism can have the same structure as the first clutch mechanism, but the clutch state is opposite. That is, when the drive shaft 200 rotates counterclockwise, the first clutch mechanism is in a coupled state, and can control the first delivery unit 1 to deliver, while the second clutch mechanism is in a separated state, and the second delivery unit 2 does not deliver. Correspondingly, when the drive shaft 200 rotates clockwise, the first clutch mechanism is in a separated state, and the first delivery unit 1 does not deliver, while at the same time, the second clutch mechanism is in a coupled state, and can control the second delivery unit 2 to deliver.

[0075] In a further solution of this embodiment, the delivery device further comprises a first shell 110, a second shell 120 and a cover 130 connected in sequence. The upper side of the second shell 120 is open, and the cover 130 is buckled at the opening of the second shell 120 to form a delivery cavity of the second delivery unit 2. The upper side of the first shell 110 is open, and the lower side of the second shell 120 is buckled at the opening of the first shell 110 to form a delivery cavity of the first delivery unit 1.

[0076] Specifically, a connecting hole 116 is provided on the first shell 110 , and the connecting hole 116 is through-through, and can be connected to the second shell 120 through an assembling part (such as a fastening screw) passing through the connecting hole 116 , thereby connecting and fixing the first shell 110 and the second shell 120 .

[0077] Furthermore, the power unit 3 is arranged at the lower part of the first delivery unit 1, and includes a mounting shell 320, and a motor 310 arranged inside the mounting shell 320. The mounting shell 320 is connected and fixed to the first housing 110, and the output shaft 311 of the motor 310 passes through the lower part of the first housing 110 and is connected to the drive shaft 200, thereby driving the drive shaft 200.

[0078] The drive shaft 200 includes a first drive shaft 210 and a second drive shaft 220 connected to each other. The first drive shaft 210 is arranged in the delivery cavity of the first delivery unit 1, and its lower end is connected to the output shaft 311, and is splined to the connecting member 420 of the first clutch mechanism to drive it to rotate. The upper end of the first drive shaft 210 is connected to the second drive shaft 220 located in the delivery cavity of the second delivery unit 2, and the second drive shaft 220 is splined to the connecting member 420 of the second clutch mechanism and drives it to rotate. The lower side surface of the cover body 130 has a positioning groove, and the upper end of the second drive shaft 220 is inserted into the positioning groove and can rotate, which ensures that the position of the upper end of the second drive shaft 220 is stable.

[0079] As a detailed solution of this embodiment, the transmission wheel 410 of the first clutch mechanism is provided with an inner groove 411 on the upper side, and a connecting member 420 and a claw 430 are provided therein, and the first drive shaft 210 passes through the transmission wheel 410 and is connected to the connecting member 420. The transmission wheel 410 of the second clutch mechanism is provided with an inner groove 411 on the lower side, that is, the connecting member 420 and the claw 430 of the second clutch mechanism are provided on the lower side of the transmission wheel 410, the lower part of the second drive shaft 220 is connected to the connecting member 420 through a spline, and the upper part passes through the transmission wheel 410 and is finally inserted into the positioning groove on the cover body 130.

[0080] Furthermore, a buckle 115 is provided on the first shell 110, and the first shell 110 can be fixed with the mounting shell 320 by the buckle 115. A positioning column 114 is also provided on the lower side of the first shell 110, and a positioning hole is provided at a corresponding position on the mounting shell 320, and the positioning column 114 is inserted into the positioning hole, so that the connection between the first shell 110 and the mounting shell 320 is more stable.

[0081] Preferably, a raised pre-positioning structure 113 is further provided on the lower surface of the first housing 110. During the assembly process, the side wall of the mounting shell 320 can be first fitted on the pre-positioning structure 113, and then the position of the mounting shell 320 can be fine-tuned so that the buckle 115 and the positioning column 114 on the first housing 110 can be correspondingly snapped into the corresponding positions on the mounting shell 320.

[0082] In this embodiment, the delivery device can use the same power unit 3 to control the delivery actions of the two delivery units, which is simple to control and can achieve the purpose of reducing costs.

[0083] Embodiment 2

[0084] like Figures 1 to 8As shown, this embodiment is a further limitation of the above-mentioned embodiment 1, and the first shell 110 is provided with a first liquid inlet 111 and a first liquid outlet 112 connected to the internal delivery chamber. When the driving wheel 410 of the first clutch mechanism rotates in the delivery chamber, the clothing treatment agent can be sucked in through the first liquid inlet 111, and then discharged from the delivery chamber through the first liquid outlet 112, thereby realizing the delivery of the clothing treatment agent.

[0085] Similarly, the second shell 120 is provided with a second liquid inlet 121 and a second liquid outlet 122 connected to the internal delivery chamber. When the transmission wheel 410 of the second clutch mechanism rotates in the delivery chamber, the clothing treatment agent can be sucked in through the second liquid inlet 121 and then discharged from the delivery chamber through the second liquid outlet 122.

[0086] When the dispensing device is used on a clothing treatment device, the first liquid inlet 111 and the second liquid inlet 121 are respectively connected to liquid storage boxes of different types of clothing treatment agents, and the first liquid outlet 112 and the second liquid outlet 122 are connected to the washing cavity of the clothing treatment agent, thereby realizing the automatic dispensing function of the clothing treatment agent.

[0087] Taking a washing machine as an example, the first liquid inlet 111 can be connected to a liquid storage chamber for detergent, the second liquid inlet 121 can be connected to a liquid storage chamber for softener, and the first liquid outlet 112 and the second liquid outlet 122 can be connected to the washing tub of the washing machine. In this way, during the washing stage, the driving shaft 200 is controlled by the power unit 3 to rotate counterclockwise, and the detergent is sucked into the dispensing chamber of the first dispensing unit 1 through the first liquid inlet 111, and then discharged into the washing tub through the first liquid outlet 112. During the rinsing stage, the driving shaft 200 is controlled by the power unit 3 to rotate clockwise, and the softener is sucked into the dispensing chamber of the second dispensing unit 2 through the second liquid inlet 121, and then discharged into the washing tub through the second liquid outlet 122.

[0088] In the specific scheme of this embodiment, an annular limiting guide rail 501 is arranged on the top wall / bottom wall of the delivery chamber, and the rotating shaft of the transmission wheel 410 is eccentrically arranged with the axis of the limiting guide rail 501, so as to form an eccentric volume chamber 500 between the transmission wheel 410 and the side wall of the delivery chamber. At least two liquid extruding rotating parts 510 that can move telescopically along the radial direction of the transmission wheel 410 are installed on the outer peripheral side wall of the transmission wheel 410. When the transmission wheel 410 rotates in the delivery chamber, the liquid extruding rotating parts 510 can be driven to slide along the limiting guide rail 501. Since the transmission wheel 410 and the axis of the limiting guide rail 501 are eccentrically arranged, during the rotation of the transmission wheel 410, the liquid extruding rotating parts 510 will move telescopically relative to the side wall of the transmission wheel 410 under the constraint of the limiting guide rail 501.

[0089] Thus, in the first delivery unit 1, see Figure 2When the driving wheel 410 of the first clutch mechanism rotates, the volume of the closed space formed by the two adjacent liquid squeezing rotating members 510 and the eccentric volume chamber 500 changes continuously, and then the clothing treatment agent enters the eccentric volume chamber 500 from the first liquid inlet 111 through the volume change of the closed space, and then is discharged from the first liquid outlet 112, thereby realizing quantitative addition of the clothing treatment agent.

[0090] In this embodiment, the number of the liquid squeezing rotating members 510 can be determined according to actual needs. Figure 2 As shown, three extruding liquid rotating members 510 are provided, and the interval between two adjacent extruding liquid rotating members 510 is 120°.

[0091] Furthermore, evenly distributed telescopic guide grooves 415 are provided on the outer peripheral side wall of the transmission wheel 410, and the extruded liquid rotating member 510 includes an extrusion portion 511 and a telescopic matching portion 512. The extrusion portion 511 is located between the outer peripheral side wall of the transmission wheel 410 and the side wall of the delivery chamber, and a closed space with a constantly changing volume is formed by the extrusion portions 511 of two adjacent extruded liquid rotating members 510 and the eccentric volume chamber 500. The telescopic guide groove 415 is extended along the radial direction of the transmission wheel 410, and the telescopic matching portion 512 is slidably inserted in the telescopic guide groove 415, so as to constrain the extruded liquid rotating member 510 to produce a telescopic movement in the radial direction relative to the transmission wheel 410.

[0092] Furthermore, the extruding liquid rotating member 510 further includes a guide rail matching portion 513 disposed on the side of the extruding portion 511 close to the limiting guide rail 501, and the guide rail matching portion 513 slidably matches with the limiting guide rail 501. Specifically, the limiting guide rail 501 is a groove structure disposed on the inner wall of the delivery cavity, and the guide rail matching portion 513 protrudes from the surface of the extruding portion 511, extends into the groove structure, and slidably matches with the limiting guide rail 501.

[0093] In the specific solution of this embodiment, the side of the driving wheel 410 provided with the inner sinking groove 411 is arranged away from the side where the limiting guide rail 501 is located, so as to avoid interference between the first clutch mechanism and the liquid extruding rotating member 510 .

[0094] In this embodiment, the second placing unit 2 may have the same structure as the first placing unit 1 , but the same structure is located in opposite directions in the two placing units.

[0095] Specifically, in the first delivery unit 1, the limiting guide rail 501 is arranged on the bottom wall of the delivery cavity, that is, on the bottom inner wall of the first housing 110, and the inner sinking groove 411 is arranged on the upper side of the transmission wheel 410. In the second delivery unit 2, the limiting guide rail 501 is arranged on the top wall of the delivery cavity, that is, on the lower surface of the cover 130, and the inner sinking groove 411 is arranged on the lower side of the transmission wheel 410.

[0096] When the dispensing device described in this embodiment is working, when the power unit 3 controls the driving shaft 200 to rotate counterclockwise, the first clutch mechanism is in a coupled state, which can drive the transmission wheel 410 in the dispensing chamber of the first dispensing unit 1 to rotate counterclockwise, thereby causing the liquid extruding rotating member 510 to rotate and move radially, thereby sucking the clothing treatment agent into the eccentric volume chamber 500 of the first dispensing unit 1 and then discharging it, so that the first dispensing unit 1 performs the dispensing operation. At the same time, the second clutch mechanism is in a disengaged state, and the transmission wheel 410 in the dispensing chamber of the second dispensing unit 2 remains stationary, so the second dispensing unit 2 will not perform dispensing.

[0097] When the power unit 3 controls the driving shaft 200 to rotate clockwise, the first clutch mechanism is in a disengaged state, the transmission wheel 410 in the delivery chamber of the first delivery unit 1 remains stationary, and the first delivery unit 1 does not deliver. The second clutch mechanism is in a coupled state, which can drive the transmission wheel 410 in the delivery chamber of the second delivery unit 2 to rotate clockwise, and then the liquid extruding rotating member 510 rotates and moves radially, so that the laundry treatment agent is sucked into the eccentric volume chamber 500 of the second delivery unit 2 and then discharged, so that the second delivery unit 2 performs the delivery operation.
