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, which is transmission-connected to the first delivery unit via the first clutch mechanism, and is transmission-connected to the second delivery unit via the second clutch mechanism;

[0012] The first clutch mechanism comprises:

[0013] A transmission wheel, a claw is hingedly connected to an area near the outer periphery on one side surface of the transmission wheel;

[0014] A connecting wheel is arranged on one side where the transmission wheel and the claw are hinged, connected to the driving shaft and rotates therewith, and an inner sinking groove is arranged on the outer peripheral side wall of the connecting wheel;

[0015] The drive shaft drives the connected rotating wheel to rotate in a first direction, and the inner sunken retaining groove cooperates with the clamping claw to limit the position, pushing the transmission wheel to rotate synchronously, thereby controlling the first delivery unit to deliver; the drive shaft drives the connected rotating wheel to rotate in a second direction opposite to the first direction, and the inner sunken retaining groove slips off the clamping claw, and the first delivery unit does not deliver.

[0016] Furthermore, the inner sinking groove has a combination surface and a sliding surface which are parallel to the rotation axis of the transmission wheel and are arranged at a certain angle, and the combination surface and the sliding surface are arranged on the same side relative to the radial direction of the transmission wheel;

[0017] The driving shaft drives the connecting wheel to rotate in a first direction, and the engaging surface stops at the claw, pushing the transmission wheel to rotate synchronously; the driving shaft drives the connecting wheel to rotate in a second direction, and the sliding surface slides relative to the claw, and the transmission wheel remains stationary.

[0018] Furthermore, the angle between the bonding surface and the sliding surface is less than 90°.

[0019] Furthermore, the side of the claw facing away from the outer periphery of the connecting wheel extends along an arc from an area close to the hinge position and gradually approaches the outer periphery of the connecting wheel, forming a first arc surface that bends in the same direction as the outer periphery of the connecting wheel.

[0020] Furthermore, the extended end of the first arcuate surface has a matching plane extending along a straight line; when the drive shaft drives the connecting wheel to rotate in the first direction, the joint surface of the inner sunken retaining groove fits and stops against the matching plane.

[0021] Furthermore, the claw extends along an arc from an area close to the hinge position toward one side of the outer periphery of the connecting wheel, gradually approaching the outer periphery of the connecting wheel, forming a second arc surface that bends in the same direction as the outer periphery of the connecting wheel; the extended end of the second arc surface is connected to the mating plane through a rounded corner.

[0022] Furthermore, a surface of one side of the transmission wheel on which the claw is hinged is provided with an annular convex rib in the peripheral area, and the claw is located inside the area surrounded by the annular convex rib;

[0023] The first clutch mechanism also includes an elastic spring sheet arranged between the claw and the annular rib; the elastic spring sheet has a first elastic portion and a second elastic portion at a certain angle, the first elastic portion abuts against the inner side wall of the annular rib, and the second elastic portion abuts against the side of the claw facing the annular rib.

[0024] Furthermore, a side of the connecting wheel facing away from the transmission wheel is not higher than a top surface of the annular rib.

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

[0026] A clothes treating device comprises the above-mentioned clothes treating agent delivery device.

[0027] After adopting the above technical scheme, the present invention has the following beneficial effects compared with the prior art.

[0028] 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.

[0029] In the present invention, the engaging surface and the sliding surface of the inner sunken retaining groove are located on the same side relative to the radial direction of the transmission wheel, and there is an angle less than 90° between the two. In the engaged state of the first clutch mechanism, the limiting cooperation between the inner sunken retaining groove and the claw is more reliable, thereby ensuring the transmission effect on the transmission wheel; and in the disengaged state of the first clutch mechanism, the sliding of the claw relative to the sliding surface is smoother, preventing the claw and the inner sunken retaining groove from being stuck, resulting in the failure of the first clutch mechanism.

[0030] In the present invention, the claw has a first arcuate surface and a matching plane. When the first clutch mechanism is in the engaged state, the claw is in surface contact with the inner sinking groove, which can more effectively transmit torque. The second arcuate surface of the claw reserves an escape space on the side close to the connecting wheel, ensuring that when the first clutch mechanism is in the disengaged state, the connecting wheel and the transmission wheel can rotate relative to each other without hindrance.

[0031] 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

DETAILED DESCRIPTION

[0043] 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.

[0045] In the description of the present invention, it should be noted that, unless otherwise clearly specified and limited, the terms "installed", "connected", and "connected" should be understood in a broad sense, for example, it 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. For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.

[0046] Embodiment 1

[0047] like Figures 1 to 8 As 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.

[0048] 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.

[0049] 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.

[0050] 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.

[0051] 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.

[0052] In this embodiment, the specific structure of the first clutch mechanism is shown in Figures 2 to 5 As shown, it includes a transmission wheel 410 and a connecting wheel 440. Among them, the upper surface of the transmission wheel 410 is hinged with a claw 430 in the area close to the periphery, and the connecting wheel 440 is arranged on the upper side of the transmission wheel 410 and is connected to the driving shaft 200 and rotates therewith. Through the clutch cooperation between the connecting wheel 440 and the claw 430, the driving shaft 200 can be rotated forward and reversely, and the torque is transmitted to one of the first delivery unit 1 and the second delivery unit 2.

[0053] Specifically, the outer peripheral side wall of the connecting wheel 440 is provided with an inner sinking groove 441 for realizing the clutching and engaging with the claw 430. During the operation of the delivery device, if the driving shaft 200 drives the connecting wheel 440 to the first direction (i.e. Figure 2 ), the inner stop groove 441 can cooperate with the claw 430 to limit the position, 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) is rotated counterclockwise as shown in the figure, the inner sinking stop groove 441 and the claw 430 slip off, and the first delivery unit 1 does not deliver at this time.

[0054] Furthermore, the inner retaining groove 441 described in this embodiment has a coupling surface 442 and a sliding surface 443 at a certain angle, and the coupling surface 442 and the sliding surface 443 are parallel to the rotation axis of the transmission wheel 410. With respect to the radial direction of the transmission wheel 410, the coupling surface 442 and the sliding surface 443 are arranged on the same side.

[0055] When the driving shaft 200 drives the connecting wheel 440 to rotate clockwise, the joint surface 442 of the inner sinking stop groove 441 stops against the claw 430, so that the claw 430 rotates with the connecting wheel 440, thereby driving the transmission wheel 410 to rotate synchronously, and controlling the first delivery unit 1 to deliver. When the driving shaft 200 drives the connecting wheel 440 to rotate counterclockwise, the claw 430 can swing a certain angle relative to the transmission wheel 410, so that the sliding surface 443 of the inner sinking stop groove 441 slides relative to the claw 430, and the claw 430 can slip out of the inner sinking stop groove 441 without rotating with the connecting wheel 440, and then the transmission wheel 410 also remains stationary, so that the first delivery unit 1 does not deliver.

[0056] Since the engaging surface 442 and the sliding surface 443 are inclined toward the same side relative to the radial direction of the transmission wheel 410, the clutching and engaging effect with the claw 430 is better. When the first clutch mechanism is in the engaged state, the limiting cooperation between the inner sinking retaining groove 441 and the claw 430 is more reliable, ensuring the transmission effect. When the first clutch mechanism is in the disengaged state, the relative sliding between the claw 430 and the sliding surface 443 is smoother, which can prevent the claw 430 from getting stuck with the inner sinking retaining groove 441, causing the problem of failure of the first clutch mechanism.

[0057] In this embodiment, a plurality of inner sunken retaining grooves 441 are evenly distributed along the circumference of the connecting wheel 440. When the connecting wheel 440 rotates clockwise, the claw 430 is inserted into one of the inner sunken retaining grooves 441 and rotates with the connecting wheel 440. When the connecting wheel 440 rotates counterclockwise, the claw 430 slips out of one inner sunken retaining groove 441. As the connecting wheel 440 continues to rotate, the claw 430 re-enters another adjacent inner sunken retaining groove 441 and then slips out again, and the cycle repeats until the connecting wheel 440 stops rotating.

[0058] The claw 430 may be provided with only one, or may be provided with two or more. Figure 2 Two claws 430 are provided, and the two claws 430 are located on the same side of the diameter of the transmission wheel 410.

[0059] Furthermore, an elastic member is provided between the claw 430 and the transmission wheel 410, and the elastic force is used to keep the claw 430 and the transmission wheel 410 in a Figure 2 The relative position relationship shown. When the connecting wheel 440 rotates counterclockwise, the claw 430 swings clockwise at a certain angle relative to the transmission wheel 410 and slides along the sliding surface 443, so that the first clutch mechanism is in a disengaged state. After the claw 430 completely slips out of the current inner sinking groove 441, when the other inner sinking groove 441 rotates to the position where the claw 430 is located, the claw 430 can automatically reset under the action of the elastic member and enter the other inner sinking groove 441. In this way, when the connecting wheel 440 stops rotating counterclockwise and rotates clockwise again, the claw 430 can stop at the joint surface 442 of the current inner sinking groove 441, rotate with the connecting wheel 440, and then drive the transmission wheel 410 to rotate.

[0060] Specifically, in two adjacent inner sinking grooves 441, the sliding surface 443 of one inner sinking groove 441 is connected to the bonding surface 442 of the other inner sinking groove 441 through the arc-shaped outer peripheral side wall of the connecting wheel 440. After the claw 430 completely slips out of the previous inner sinking groove 441, it continues to slide along the arc-shaped outer peripheral side wall of the connecting wheel 440 until it enters the next inner sinking groove 441.

[0061] As a specific implementation of this embodiment, the elastic member is an elastic spring 417. Specifically, an annular rib 416 is provided on the upper surface of the transmission wheel 410 in the peripheral area, and the claw 430 is located inside the area surrounded by the annular rib 416.

[0062] The elastic spring 417 is a V-shaped spring having a first elastic portion 418 and a second elastic portion 419 at a certain angle. The first elastic portion 418 abuts against the inner wall of the annular rib 416, and the second elastic portion 419 abuts against the side of the claw 430 facing the annular rib 416.

[0063] Under normal conditions, the second elastic part 419 applies elastic force to the claw 430, causing the claw 430 to be stuck in the inner sinking groove 441. When the connecting wheel 440 rotates counterclockwise, the claw 430 slides along the sliding surface 443 and swings a certain angle, compressing the second elastic part 419 to move closer to the first elastic part 418. After the claw 430 completely slips out of the current inner sinking groove 441, when another inner sinking groove 441 rotates to the position where the claw 430 is located, the second elastic part 419 will push the claw 430 to swing back to reset, thereby the other inner sinking groove 441.

[0064] It is understandable that the elastic member may also be a spring, a torsion spring, etc., as long as the claw 430 can be automatically reset after rotating.

[0065] Further, in this embodiment, the side of the connecting wheel 440 facing away from the transmission wheel 410 is not higher than the top surface of the annular rib 416. As a preferred solution, the thickness of the claw 430 is less than or equal to the protruding height of the annular rib 416, and the thickness of the connecting wheel 440 is less than the thickness of the claw 430.

[0066] 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, on the one hand, the overall structure composed of the transmission wheel 410, the clamping claw 430 and the connecting rotating wheel 440 can be made as compact as possible, reducing the required installation space, which is helpful to realize the miniaturization design of the delivery device. On the other hand, the thickness of the clamping claw 430 is greater than the thickness of the connecting rotating wheel 440, which makes it easier to ensure the stable cooperation between the clamping claw 430 and the inner sinking retaining groove 441.

[0067] In a further solution of this embodiment, the angle between the joint surface 442 and the sliding surface 443 is less than 90°. In this way, the inner sinking groove 441 and the claw 430 are better connected, and the claw 430 is pushed by the connecting wheel 440, driving the transmission wheel 410 to rotate synchronously with the connecting wheel 440.

[0068] In this embodiment, further, the side of the claw 430 facing away from the periphery of the connecting wheel 440 extends along an arc from the area close to the hinge position and gradually approaches the periphery of the connecting wheel 440 to form a first arc surface 435 that bends in the same direction as the periphery of the connecting wheel 440.

[0069] Furthermore, the extended end of the first arc surface 435 has a matching plane 437 extending along a straight line. When the driving shaft 200 drives the connecting wheel 440 to rotate clockwise, the joint surface 442 of the inner stop groove 441 is in contact with the matching plane 437 to stop.

[0070] Preferably, the extension length of the matching plane 437 is greater than the length of the bonding surface 442 in the same extension direction, so that the bonding surface 442 is completely fitted on the matching plane 437 .

[0071] Through the above structure, when the first clutch mechanism is in the engaged state, the contact area between the connecting wheel 440 and the claw 430 is maximized, which makes it easier to achieve the effect of stable torque transmission between the connecting wheel 440 and the claw 430, thereby reducing the torque output by the power unit 3 to the drive shaft 200.

[0072] Furthermore, the claw 430 extends from the area near the hinge position toward the outer periphery of the connecting wheel 440 along an arc to gradually approach the outer periphery of the connecting wheel 440, forming a second arc surface 436 that is curved in the same direction as the outer periphery of the connecting wheel 440. The extended end of the second arc surface 436 is connected to the matching plane 437 through a rounded corner.

[0073] In the above scheme, both sides of the claw 430 have an arc surface structure, which can make full use of the installation space on the upper side of the transmission wheel 410. In particular, the second arc surface 436 has a space for avoidance on the side close to the connecting wheel 440, which can avoid interference between the connecting wheel 440 and the claw 430 when the first clutch mechanism is in a disengaged state, ensuring that the connecting wheel 440 and the transmission wheel 410 can rotate relative to each other without hindrance. There is a rounded corner between the second arc surface 436 and the matching plane 437, which effectively reduces the resistance caused by sliding friction when the claw 430 slides along the sliding surface 443 and the outer peripheral side wall of the connecting wheel 440.

[0074] In this embodiment, the claw 430 is hinged to the transmission wheel 410 through a joint shaft 431. As a specific implementation, the joint shaft 431 is a column protruding from the upper surface of the transmission wheel 410, and a circular hole is provided on the claw 430, and the joint shaft 431 is rotatably inserted in the circular hole, thereby realizing the hinged connection between the claw 430 and the transmission wheel 410.

[0075] The claw 430 has an arc side wall at one end close to the circular hole, which is cocentric with the circular hole, and two ends of the arc side wall are respectively connected to the starting ends of the first arc surface 435 and the second arc surface 436 .

[0076] As a preferred solution of this embodiment, there is a rounded transition between the engagement surface 442 and the sliding surface 443 of the inner sinking retaining groove 441. When the first clutch mechanism is in the engaged state, the engagement surface 442 is completely fitted with the matching plane 437 of the claw 430, and the rounded corner between the matching plane 437 and the second arc surface 436 on the claw 430 is fitted with the rounded corner between the engagement surface 442 and the sliding surface 443 in the inner sinking retaining groove 441.

[0077] By adopting the above structure, the contact area between the inner retaining groove 441 and the claw 430 is further increased when the first clutch mechanism is in the engaged state, thereby ensuring the torque transmission effect.

[0078] In this embodiment, when the delivery device is working, the driving shaft 200 can be driven to rotate at high speed by the power unit 3. By designing the size of the inner sinking groove 441 and the claw 430, when the first clutch mechanism is in the disengaged state, the claw 430 can quickly enter the inner sinking groove 441 and then slide off, and the reciprocating swing angle of the claw 430 in this process is small, thereby avoiding abnormal noise during the working process.

[0079] 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 clockwise, 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 counterclockwise, 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.

[0080] It is understandable that the second clutch mechanism may also adopt a different structure, as long as its clutch state is opposite to that of the first clutch mechanism.

[0081] 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.

[0082] Specifically, the first housing 110 is provided with a connection hole 116, which is through-through, and can be connected to the second housing 120 through an assembly part (such as a fastening screw) passing through the connection hole 116, thereby connecting and fixing the first housing 110 and the second housing 120. The second housing 120 and the cover 130 can also be fixed in a similar connection manner.

[0083] 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.

[0084] 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 2, and its lower end is connected to the output shaft 311, and is splined to the connecting wheel 440 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 wheel 440 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.

[0085] As a detailed solution of this embodiment, the connecting wheel 440 and the claw 430 of the first clutch mechanism are both arranged on the upper side of the transmission wheel 410, and the first drive shaft 210 passes through the transmission wheel 410 and is connected to the connecting wheel 440. The connecting wheel 440 and the claw 430 of the second clutch mechanism are arranged on the lower side of the transmission wheel 410, the lower part of the second drive shaft 220 is connected to the connecting wheel 440 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.

[0086] 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.

[0087] 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.

[0088] 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.

[0089] Embodiment 2

[0090] 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.

[0091] 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.

[0092] 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.

[0093] 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 clockwise, and the detergent is sucked into the dispensing chamber of the first dispensing unit 1 from the first liquid inlet 111, and then discharged from the first liquid outlet 112 into the washing tub, while the second dispensing unit 2 does not dispense at this time. During the rinsing stage, the driving shaft 200 is controlled by the power unit 3 to rotate counterclockwise, and at this time the first dispensing unit 1 does not dispense, and the softener is sucked into the dispensing chamber of the second dispensing unit 2 from the second liquid inlet 121, and then discharged from the second liquid outlet 122 into the washing tub.

[0094] 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.

[0095] Thus, in the first delivery unit 1, see Figure 2 When 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.

[0096] 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°.

[0097] 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.

[0098] Since the connecting wheel 440 and the claw 430 are arranged on the upper side of the transmission wheel 410 and do not occupy the space inside the transmission wheel 410, the setting area of ​​the connecting wheel 440 and the claw 430 can overlap with the setting range of the telescopic guide groove 415. In this way, the extension length of the telescopic guide groove 415 and the telescopic matching part 512 can be as long as possible, especially when the liquid extruding rotating member 510 is extended to the extreme position, the telescopic matching part 512 has a larger length still located in the telescopic guide groove 415, which can ensure the stable matching of the telescopic guide groove 415 and the telescopic matching part 512.

[0099] 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.

[0100] In a specific solution of this embodiment, the side of the transmission wheel 410 where the claw 430 is hinged is arranged away from the side where the limiting guide rail 501 is located, which can avoid interference between the first clutch mechanism and the liquid squeezing rotating member 510.

[0101] In this embodiment, the second placing unit 2 may have the same structure as the first placing unit 1 , but the orientations of the same structure in the two placing units are opposite.

[0102] 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 claw 430 and the connecting wheel 440 are 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 claw 430 and the connecting wheel 440 are arranged on the lower side of the transmission wheel 410.

[0103] When the dispensing device described in this embodiment is working, when the power unit 3 controls the driving shaft 200 to rotate clockwise, 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 clockwise, 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.

[0104] When the power unit 3 controls the driving shaft 200 to rotate counterclockwise, 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 counterclockwise, 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.

[0105] The above is only a preferred embodiment of the present invention, and does not limit the present invention in any form. Although the present invention has been disclosed as a preferred embodiment, it is not used to limit the present invention. Any technician familiar with this patent can make some changes or modify the technical contents suggested above into equivalent embodiments without departing from the scope of the technical solution of the present invention. However, any simple modification, equivalent change and modification made to the above embodiments according to the technical essence of the present invention without departing from the content of the technical solution of the present invention still fall within the scope of the solution of the present invention.
