Description

Technical Field

[0001] The present invention belongs to the technical 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] The Chinese patent application number CN201310415596.7 discloses an automatic detergent adding device and a washing device, wherein a ratchet and a pawl cooperate to realize that a power source drives the driving shaft to rotate forward and reverse, and accordingly the first pumping unit or the second pumping unit is operated to add detergent. However, in this solution, the overrunning clutch composed of the ratchet and the pawl will generate obvious working noise when it is in a disengaged state without transmitting torque, which affects the user experience.

[0006] In view of this, the present invention is proposed. Summary of the invention

[0007] The technical problem to be solved by the present invention is to overcome the shortcomings of the prior art and provide a dispensing device and a clothing processing equipment, which can drive the driving shaft forward and reverse by a power source to realize the control of selecting one of the two dispensing units for dispensing, and at the same time, the dispensing unit that does not dispense will not produce abnormal noise.

[0008] In order to solve the above technical problems, the basic concept of the technical solution adopted by the present invention is:

[0009] A delivery device, comprising:

[0010] A first delivery unit, comprising a first clutch mechanism;

[0011] A second delivery unit includes a second clutch mechanism having a clutch state opposite to that of the first clutch mechanism;

[0012] 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;

[0013] The first clutch mechanism comprises:

[0014] A transmission wheel, on which a first limiting structure is arranged;

[0015] A clutch member is movably mounted on the driving shaft, and a second limiting structure is provided on the clutch member;

[0016] The driving shaft rotates in the first direction, driving the clutch to move along the axial direction of the driving shaft toward the transmission wheel, so that the second limiting structure and the first limiting structure are limitedly matched, and the clutch rotates with the driving shaft to drive the transmission wheel to rotate synchronously, thereby controlling the first delivery unit to deliver;

[0017] The driving shaft rotates in a second direction opposite to the first direction, driving the clutch member to move axially along the driving shaft away from the transmission wheel, the second limiting structure is separated from the first limiting structure, and the first delivery unit does not deliver.

[0018] Furthermore, the drive shaft has a threaded section, and the clutch member can be spirally mounted on the threaded section of the drive shaft, and moves closer to or farther from the transmission wheel as the drive shaft rotates;

[0019] When the clutch moves to one end of the threaded segment close to the transmission wheel, the second limiting structure and the first limiting structure are limited and cooperated, and the driving shaft continues to rotate in the same direction to drive the clutch to rotate synchronously; when the clutch moves to the other end of the threaded segment, the second limiting structure is completely separated from the first limiting structure.

[0020] Furthermore, the side wall of the threaded section has an external thread structure, and the inner wall of the central hole of the clutch has an internal thread structure matching the external thread;

[0021] The driving shaft also has a limiting section, which is connected to one end of the threaded section close to the transmission wheel; the outer diameter of the limiting section is larger than the diameter surrounded by the top of the internal thread structure on the inner wall of the central hole of the clutch;

[0022] Preferably, the outer diameter of the limiting segment is equal to the diameter enclosed by the top end of the external thread structure on the thread segment.

[0023] Furthermore, the first clutch mechanism further comprises an elastic clamping assembly; when the clutch member is located between the two ends of the threaded segment, the elastic force provided by the elastic clamping assembly is used to clamp the clutch member to remain stationary in the circumferential direction.

[0024] Further, the elastic clamping assembly comprises a first elastic member and a second elastic member which are arranged parallel to the axial direction of the driving shaft;

[0025] The first elastic member is arranged between the transmission wheel and the clutch member, with one end fixed on the transmission wheel and the other end abutting against the clutch member; the second elastic member is arranged on the side of the clutch member facing away from the transmission wheel, with one end fixed and the other end abutting against the clutch member.

[0026] Further, the first delivery unit has a delivery cavity, the first clutch mechanism is arranged in the delivery cavity of the first delivery unit; the second elastic member is arranged between the clutch member and the inner wall of the delivery cavity, and one end of the second elastic member is fixed to the inner wall of the delivery cavity;

[0027] Preferably, the first elastic member and the second elastic member are both compression springs sleeved on the drive shaft.

[0028] Furthermore, the first limiting structure is a limiting convex part / a limiting groove, and the second limiting structure is a limiting groove / a limiting convex part;

[0029] The clutch moves along the drive shaft toward the transmission wheel, so that the limiting protrusion is inserted into the limiting groove; or the clutch moves along the drive shaft away from the transmission wheel, so that the limiting protrusion is disengaged from the limiting groove.

[0030] Furthermore, a clamping arm extending radially along the transmission wheel is provided on one side surface of the transmission wheel facing the clutch member, and the limiting groove is provided on one end of the clamping arm close to the center of the transmission wheel;

[0031] The clutch member comprises a main body with a circular outer contour, and the main body is mounted on the driving shaft; the limiting protrusion is arranged on a side surface of the main body facing the transmission wheel and in an area close to the outer periphery.

[0032] Further, the second delivery unit has the same structure as the first delivery unit; and / or the second clutch mechanism has the same structure as the first clutch mechanism.

[0033] A clothes processing device comprises the above-mentioned placing device.

[0034] After adopting the above technical scheme, the present invention has the following beneficial effects compared with the prior art.

[0035] 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.

[0036] In the present invention, a threaded fit is adopted between the driving shaft and the clutch member, and the clutch member can be driven to approach or move away from the transmission wheel by the forward and reverse rotation of the driving shaft. When the first delivery unit is controlled not to deliver, the second limiting structure on the clutch member and the first limiting structure on the transmission wheel are in a completely separated state, so that no abnormal sound is generated during the operation, thereby improving the user experience.

[0037] In the present invention, the clutch is clamped from both sides by an elastic clamping structure, which can not only limit the circumferential rotation of the clutch, but also the elastic clamping structure can be retracted and will not affect the movement of the clutch along the drive shaft toward or away from the transmission wheel. The structure is simple and effective.

DETAILED DESCRIPTION

[0048] 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.

[0050] 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.

[0051] Embodiment 1

[0052] like Figures 1 to 6 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.

[0053] 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.

[0054] 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.

[0055] 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 mechanism is in the disengaged state, that is, the drive shaft 200 cannot transmit torque through the second clutch mechanism, and vice versa.

[0056] 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.

[0057] 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 and a clutch 450, wherein the transmission wheel 410 is provided with a first limiting structure, and the clutch 450 is installed on the drive shaft 200 and has a second limiting structure thereon. The drive shaft 200 and the clutch 450 are in transmission cooperation, and the rotation of the drive shaft 200 can drive the clutch 450 to move along the axial direction of the drive shaft 200 to approach or move away from the transmission wheel 410.

[0058] As a specific implementation, the first limiting structure is arranged on one side of the transmission wheel 410, and the clutch member 450 is located on the side of the transmission wheel 410 where the first limiting structure is arranged, and can approach or move away from the transmission wheel 410 axially along the driving shaft 200 as the driving shaft 200 rotates.

[0059] During the operation of the delivery device, if the drive shaft 200 moves in the first direction (i.e. Figure 2 ) can drive the clutch 450 to move axially along the drive shaft 200 toward the transmission wheel 410, so that the second limiting structure on the clutch 450 and the first limiting structure on the transmission wheel 410 are limited and matched. At this time, the clutch 450 rotates with the drive shaft 200, which can drive the transmission wheel 410 to rotate synchronously, thereby controlling the first dispensing unit 1 to dispense the laundry treatment agent. If the drive shaft 200 is rotated in a second direction opposite to the first direction (i.e. Figure 3 The clutch member 450 is driven to move in the opposite direction along the axial direction of the driving shaft 200 and away from the transmission wheel 410, so that the second limiting structure is separated from the first limiting structure, and the first delivery unit 1 does not deliver at this time.

[0060] As a specific implementation of this embodiment, a threaded transmission method is adopted between the drive shaft 200 and the clutch 450. Specifically, the drive shaft 200 has a threaded section, and the clutch 450 can be spirally mounted on the threaded section of the drive shaft 200, so as to approach or move away from the transmission wheel 410 as the drive shaft 200 rotates.

[0061] When the clutch 450 is located away from the transmission wheel 410, the clutch 450 does not rotate during the counterclockwise rotation of the drive shaft 200, and can move closer to the transmission wheel 410 along the drive shaft 200. When the clutch 450 moves to the end of the threaded section close to the transmission wheel 410, the second limiting structure and the first limiting structure achieve limiting cooperation. At this time, the drive shaft 200 continues to rotate in the same direction to drive the clutch 450 to rotate synchronously, and then drives the transmission wheel 410 to rotate. When the drive shaft 200 rotates clockwise, it can drive the clutch 450 to move in the direction away from the transmission wheel 410. When the clutch 450 moves to the other end of the threaded section, it is necessary to ensure that the second limiting structure is completely separated from the first limiting structure.

[0062] In the solution of this embodiment, when the first clutch mechanism is in the engaged state, the first limiting structure and the second limiting structure cooperate to drive the transmission wheel 410 to rotate, so that the first delivery unit 1 performs the delivery operation. When the first clutch mechanism is in the separated state, the first limiting structure and the second limiting structure are completely separated, so that the transmission wheel 410 remains stationary. Compared with the clutch structure formed by the ratchet and the pawl in the prior art, when the first delivery unit 1 is not delivering during operation, the first limiting structure and the second limiting structure are completely separated and do not contact, so no abnormal sound is generated, which improves the user experience.

[0063] In a further solution of this embodiment, in order to ensure that the rotation of the drive shaft 200 can be converted into the up and down movement of the clutch 450, it is necessary to limit the circumferential rotation of the clutch 450.

[0064] Specifically, the first clutch mechanism further includes an elastic clamping assembly (not shown in the figure). When the clutch 450 is located between the two ends of the threaded section on the drive shaft 200, the elastic force provided by the elastic clamping assembly is used to clamp the clutch 450 to remain stationary in the circumferential direction. When the clutch 450 moves to one end of the threaded section close to the transmission wheel 410, the longitudinal movement of the clutch 450 is restricted, so that the rotation of the drive shaft 200 transmits torque to the clutch 450. The torque enables the clutch 450 to overcome the elastic force provided by the elastic clamping assembly and rotate synchronously with the drive shaft 200, thereby driving the transmission wheel 410 to rotate.

[0065] As a specific solution, the elastic clamping assembly includes a first elastic member and a second elastic member arranged parallel to the axial direction of the driving shaft 200. The first elastic member is arranged between the transmission wheel 410 and the clutch member 450, one end of which is fixed on the transmission wheel 410, and the other end is abutted against the clutch member 450. The second elastic member is arranged on the side of the clutch member 450 facing away from the transmission wheel 410, one end of which is fixed, and the other end is abutted against the clutch member 450.

[0066] Specifically, the first delivery unit 1 has a delivery cavity, and the first clutch mechanism is arranged in the delivery cavity of the first delivery unit 1. The second elastic member is arranged between the clutch member 450 and the inner wall of the delivery cavity, and one end of the second elastic member is fixed to the inner wall of the delivery cavity.

[0067] More specifically, the first elastic member and the second elastic member described in this embodiment are both compression springs mounted on the drive shaft 200. One end of the compression spring is fixed, and the other end abuts against the clutch member 450 but is not fixed. The compression spring is in a compressed state, exerting elastic force on the upper and lower sides of the clutch member 450, thereby limiting the clutch member 450 from circumferential rotation through the friction between the end of the compression spring and the surface of the clutch member 450.

[0068] When the clutch 450 moves to one end of the threaded section close to the transmission wheel 410, the longitudinal movement of the clutch 450 is restricted and cannot get further close to the transmission wheel 410. At this time, due to the threaded matching structure between the drive shaft 200 and the clutch 450, the drive shaft 200 continues to rotate and transmits torque to the clutch 450, so that the clutch 450 can overcome the friction between it and the end of the compression spring, thereby rotating synchronously with the drive shaft 200.

[0069] Furthermore, in order to limit the clutch 450 in the longitudinal direction when it moves to the end of the threaded segment, in a specific solution of this embodiment, the drive shaft 200 also has a limiting segment, which is connected to one end of the threaded segment close to the transmission wheel 410.

[0070] More specifically, the side wall of the threaded section has an external thread structure, and the inner wall of the center hole of the clutch 450 has an internal thread structure matching the external thread. The outer diameter of the limit section is larger than the diameter surrounded by the top of the internal thread structure, so when the clutch 450 moves to the junction of the threaded section and the limit section, it cannot continue to move into the range of the limit section.

[0071] In the above solution, preferably, the outer diameter of the limit section is equal to the diameter surrounded by the top of the external thread structure on the thread section. With the above structure, a cylindrical shaft with a consistent outer diameter over the entire length is selected, and the thread structure is directly processed within a certain length range of its side wall, so that the drive shaft 200 in this embodiment can be obtained, and the manufacturing process is simpler.

[0072] In another specific solution of the present embodiment, the above-mentioned limiting section may not be provided on the driving shaft 200, but the longitudinal movement of the clutch member 450 is limited by the first elastic member.

[0073] Therefore, in the above solution, the length range occupied by the threaded section on the drive shaft 200 may be only the longitudinal movement range required by the clutch 450, or the entire length of the drive shaft 200 may have an external thread structure on the side wall.

[0074] Specifically, the first elastic member is a compression spring, and the compression spring has a shortest length that can be achieved after being compressed. By selecting a compression spring with appropriate parameters, the shortest length that can be achieved after being compressed can be exactly equal to the spacing distance between the clutch member 450 and the transmission wheel 410 when the first limiting structure and the second limiting structure achieve limiting cooperation.

[0075] With the above solution, when the clutch 450 moves along the drive shaft 200 and gradually approaches the transmission wheel 410, the compression spring as the first elastic member will be gradually compressed and shortened. When the first limiting structure and the second limiting structure achieve limiting cooperation, the compression spring is just compressed to the above-mentioned shortest length. At this time, since the compression spring cannot be further shortened, the drive shaft 200 continues to rotate and cannot drive the clutch 450 to get closer to the transmission wheel 410. Therefore, the clutch 450 can rotate synchronously with the drive shaft 200 under the drive of the threaded cooperation structure.

[0076] In a further solution of this embodiment, the first limiting structure is a limiting groove 461, and the second limiting structure is a limiting convex portion 452. When the clutch 450 moves along the drive shaft 200 toward the transmission wheel 410, the limiting convex portion 452 can be inserted into the limiting groove 461 to achieve transmission cooperation between the clutch 450 and the transmission wheel 410. When the clutch 450 moves along the drive shaft 200 away from the transmission wheel 410, the limiting convex portion 452 is disengaged from the limiting groove 461, and then the transmission wheel 410 no longer rotates with the drive shaft 200 and can remain stationary.

[0077] It can be understood that the setting positions of the limiting protrusion and the limiting groove can be swapped, that is, the first limiting structure arranged on the transmission wheel is the limiting protrusion, and the second limiting structure arranged on the clutch is the limiting groove, which can also achieve the transmission purpose between the clutch and the transmission wheel.

[0078] In a specific solution of this embodiment, a clamping arm 460 extending radially along the transmission wheel 410 is provided on one side surface of the transmission wheel 410 facing the clutch 450, and a limiting groove 461 is provided at one end of the clamping arm 460 close to the center of the transmission wheel 410. The clutch 450 includes a main body 451 with a circular outer profile, the main body 451 is mounted on the drive shaft 200, and the limiting protrusion 452 is provided on the side surface of the main body 451 facing the transmission wheel 410 in an area close to the outer periphery.

[0079] More specifically, a mounting seat 463 is provided on the upper side of the transmission wheel 410, and one end of the clamp arm 460 close to the outer periphery of the transmission wheel 410 is rotatably mounted on the mounting seat 463 via a rotating shaft 462. The clamp arm 460 can rotate up and down around the rotating shaft 462, so that the limiting groove 461 has a certain movable range in the vertical direction. With the above structure, the up and down movement range of the clutch member 450 does not need to be set very accurately, which reduces the difficulty of production.

[0080] Specifically, when the clutch 450 moves downward and approaches the transmission wheel 410, when the limiting protrusion 452 has been inserted into the limiting groove 461 on the clamp arm 460, if the longitudinal movement of the clutch 450 is still not restricted at this time, and the clamp arm 460 cannot move, continuing to press down the end of the clamp arm 460 may cause structural damage. However, if the clamp arm 460 is set to be able to rotate up and down, the clutch 450 can be further lowered to press down the end of the clamp arm 460 to rotate downward until it contacts the transmission wheel 410 below. In this way, there is no need to accurately set the limit position of the downward movement of the clutch 450 to the height at which the limiting protrusion 452 is just inserted into the limiting groove 461, and there is no need to worry about position errors causing structural damage.

[0081] Furthermore, the mounting seat 463 has a limiting portion 464 located above the clamping arm 460, which is used to limit the maximum angle of the clamping arm 460 to rotate upward. Specifically, when the clutch 450 moves upward, the limiting groove 461 at the end of the clamping arm 460 may be stuck by the limiting protrusion 452, and then the limiting protrusion 452 rises synchronously, driving the clamping arm 460 to rotate upward. When the clamping arm 460 rotates until the upper surface contacts the limiting portion 464, the limiting portion 464 can limit the clamping arm 460 from further rotating upward, and the clutch 450 will continue to rise, thereby ensuring that the limiting protrusion 452 can be completely disengaged from the limiting groove 461.

[0082] Through the above structure, the problem that the limiting protrusion 452 and the limiting groove 461 cannot be separated is effectively avoided, thereby ensuring the effectiveness of the first clutch mechanism.

[0083] In this embodiment, the number of the clamping arms 460 is the same as the number of the upper limit projections 452 of the clutch member 450, so that they correspond one to one. The specific number of the two can be determined as needed. In a specific implementation, Figure 2 As shown, three clamping arms 460 are provided, and the interval between two adjacent clamping arms 460 is 120°.

[0084] In this embodiment, the second clutch mechanism can have the same structure as the first clutch mechanism, except that the clutch state is opposite. That is, when the drive shaft 200 rotates counterclockwise, the first clutch mechanism switches to the engaged state, and can control the first delivery unit 1 to deliver, while the second clutch mechanism switches to the separated state, and the second delivery unit 2 does not deliver. Correspondingly, when the drive shaft 200 rotates clockwise, the first clutch mechanism switches to the separated state, and the first delivery unit 1 does not deliver, while at the same time, the second clutch mechanism switches to the engaged state, and can control the second delivery unit 2 to deliver.

[0085] 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.

[0086] 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.

[0087] 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.

[0088] Specifically, the lower end of the drive shaft 200 is connected to the output shaft 311, and passes through the bottom walls of the first shell 110 and the second shell 120 in sequence. The upper end of the drive shaft 200 is inserted into the positioning groove on the lower surface of the cover body 130 and can rotate. By setting the positioning groove on the cover body 130, the upper end of the drive shaft 200 is limited, ensuring the position stability of the upper end of the drive shaft 200. In order to achieve clutch control, the drive shaft 200 has a certain length of threaded section in each of the delivery cavities of the first delivery unit 1 and the second delivery unit 2.

[0089] As a detailed solution of this embodiment, the clutch member 450 of the first clutch mechanism is arranged on the upper side of the transmission wheel 410, the clamp arm 460 is arranged on the upper surface of the transmission wheel 410, the drive shaft 200 passes through the transmission wheel 410 and is connected to the clutch member 450, and has a thread segment of a certain length in the area above the transmission wheel 410. The clutch member 450 of the second clutch mechanism is arranged on the lower side of the transmission wheel 410, the clamp arm 460 is arranged on the lower surface of the transmission wheel 410, and the drive shaft 200 has a thread segment of a certain length in the area below the transmission wheel 410, so as to be connected to the clutch member 450, and the drive shaft 200 passes through the transmission wheel 410 and is finally inserted into the positioning groove on the cover body 130.

[0090] 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.

[0091] 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.

[0092] 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.

[0093] Embodiment 2

[0094] like Figures 1 to 6 As 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.

[0095] 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.

[0096] 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.

[0097] 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.

[0098] 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 rotation axis 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 axes of the transmission wheel 410 and 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.

[0099] Thus, in the first delivery unit 1, see Figure 2 When the driving wheel 410 of the first clutch mechanism rotates counterclockwise with the clutch member 450, 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 the quantitative addition of the clothing treatment agent.

[0100] In this embodiment, the number of the liquid squeezing rotating members 510 can be determined according to actual needs. Figure 2 As shown, three liquid squeezing rotating members 510 are provided, and the interval between two adjacent liquid squeezing rotating members 510 is 120°.

[0101] 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.

[0102] Since the clutch 450 and the clamp arm 460 are arranged on the upper side of the transmission wheel 410 and do not occupy the space inside the transmission wheel 410, the arrangement area of ​​the clutch 450 and the clamp arm 460 can overlap with the arrangement 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 part 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.

[0103] 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.

[0104] In a specific solution of this embodiment, the clutch member 450 and the limiting guide rail 501 are respectively arranged on two opposite sides of the transmission wheel 410, so as to avoid interference between the first clutch mechanism and the liquid squeezing rotating member 510.

[0105] 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.

[0106] Specifically, in the first delivery unit 1, the limiting guide rail 501 is arranged on the bottom wall of the delivery cavity, that is, located on the bottom inner wall of the first housing 110, the clamp arm 460 is arranged on the upper side of the transmission wheel 410, and the clutch 450 is arranged above 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, located on the lower surface of the cover body 130, the clamp arm 460 is arranged on the lower side of the transmission wheel 410, and the clutch 450 is arranged below the transmission wheel 410.

[0107] When the dispensing device described in this embodiment is working, when the power unit 3 controls the driving shaft 200 to rotate counterclockwise, the clutch member 450 of the first clutch mechanism can be driven to descend, so that the first clutch mechanism switches to the engaged state, and then the transmission wheel 410 in the dispensing chamber of the first dispensing unit 1 can be driven to rotate counterclockwise, so that the liquid extruding rotating member 510 rotates accordingly and moves radially, 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 clutch member 450 of the second clutch mechanism descends with the rotation of the driving shaft 200, and separates from the clamping arm 460 on the transmission wheel 410, so that the second clutch mechanism switches to the separated state, and then the transmission wheel 410 in the dispensing chamber of the second dispensing unit 2 remains stationary, so that the second dispensing unit 2 will not perform dispensing.

[0108] When the power unit 3 controls the driving shaft 200 to rotate clockwise, the clutch member 450 of the first clutch mechanism is driven to rise and separate from the clamping arm 460, and then the first clutch mechanism is switched to the separation state, and the transmission wheel 410 in the delivery chamber of the first delivery unit 1 remains stationary, and the first delivery unit 1 will not deliver at this time. The clutch member 450 of the second clutch mechanism rises, so that the second clutch mechanism is switched to the engagement state, which can drive the transmission wheel 410 in the delivery chamber of the second delivery unit 2 to rotate counterclockwise, so that the liquid extrusion rotating member 510 rotates and moves radially, so that the clothes 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.
