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] A Chinese patent application with application number CN201310415596.7 discloses an automatic detergent adding device and a washing device, wherein a guide groove is arranged on the side wall of a pump chamber, a cam whose axis is eccentric to the axis of the guide groove is arranged in the pump chamber, and a telescopic head is slidably inserted on the outer periphery of the cam; during the rotation of the cam, the telescopic head performs telescopic movement under the constraint of the guide groove, so that the volume of the closed space formed by every two adjacent telescopic heads and the pump chamber continuously changes, and then the detergent enters the pump chamber from the liquid inlet through the change of the closed space volume, and then is discharged from the liquid outlet.

[0006] However, in the above scheme, the internal structure of the pump chamber is relatively complex, and a large number of relatively movable parts are required, which makes assembly cumbersome. At the same time, since the telescopic head telescopes relative to the cam, when the telescopic head extends out of the cam, for two adjacent closed spaces, the gap between the telescopic head and the side wall of the cam is large and difficult to seal, which may cause the two closed spaces to be connected and affect the quantitative addition of detergent.

[0007] In view of this, the present invention is proposed. Summary of the invention

[0008] 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 equipment, which can control two dispensing units to select one for dispensing through a power unit, and the internal structure of the dispensing unit is more simplified.

[0009] In order to solve the above technical problems, the basic concept of the technical solution adopted by the present invention is:

[0011] A first delivery unit and a second delivery unit;

[0012] and a power unit, which is transmission-connected to the first delivery unit via a first clutch mechanism, and is transmission-connected to the second delivery unit via a second clutch mechanism, wherein the clutch state of the second clutch mechanism is opposite to that of the first clutch mechanism;

[0013] The first delivery unit comprises:

[0015] A rotating member, rotatably disposed inside the delivery chamber, drivingly connected to the power unit via the first clutch mechanism, and comprising a rotating shaft disposed parallel to the axis of the delivery chamber;

[0016] At least two elastic sheets capable of bending and deformation are arranged to extend from the side wall of the rotating shaft to the outer periphery, the starting end of the elastic sheet is connected to the side wall of the rotating shaft, and the extended end is slidably against the side wall of the delivery cavity;

[0017] The axis of the rotating shaft is eccentrically arranged with respect to the axis of the delivery cavity; the rotating shaft rotates in the delivery cavity, driving one end of the elastic sheet to rotate accordingly, and the elastic sheet is constrained by the side wall of the delivery cavity to bend and deform.

[0018] Furthermore, the initial length of the elastic sheet is greater than or equal to the maximum distance between the side wall of the rotating shaft and the side wall of the delivery cavity.

[0019] Furthermore, a first positioning ring and a second positioning ring are fixedly arranged around the inside of the delivery cavity; the first positioning ring is arranged on a side of the delivery cavity close to the power unit, and the second positioning ring is arranged on a side of the delivery cavity away from the power unit; the elastic sheet is arranged between the first positioning ring and the second positioning ring.

[0020] Furthermore, the first delivery unit also includes a first shell and a first cover body, the first shell has an opening on the side facing away from the power unit, and the first cover body is snapped into the opening of the first shell to form a delivery cavity of the first delivery unit; the first positioning ring and the second positioning ring are fixed on the inner surface of the side wall of the first shell.

[0021] Furthermore, the rotating member further comprises a rotating shaft base, which is formed by extending the end of the rotating shaft close to the power unit toward the outer periphery;

[0022] A filling piece is also arranged in the delivery cavity, and the filling piece fills the interval area between the outer periphery of the rotating shaft base and the inner peripheral wall of the first positioning ring;

[0023] Preferably, the first positioning ring, the rotating shaft base and the filling piece have consistent dimensions along the axial direction of the rotating shaft.

[0024] Furthermore, the rotating member is movably mounted in the delivery cavity along the axial direction of the rotating shaft, the power unit includes an output shaft; and the first clutch mechanism includes:

[0025] An inclined slot is formed on a surface of the rotating member close to the power unit;

[0026] A clamping portion formed on the end surface of the output shaft;

[0027] The output shaft rotates in a first direction, and the engaging portion and the inclined slot are limitedly matched to drive the rotating member to rotate synchronously with the output shaft; the output shaft rotates in a second direction opposite to the first direction, and the engaging portion pushes the inclined slot along the axial direction of the rotating shaft and slides off the inclined slot, so that the rotating member does not rotate.

[0028] Furthermore, an axial hole is arranged on the rotating shaft, and the axial hole extends a certain length along the axial direction of the rotating shaft; a fixed shaft coaxial with the rotating shaft is fixedly arranged in the delivery cavity, and the fixed shaft can be inserted into the axial hole in a relatively slidable manner.

[0029] Furthermore, an elastic member is mounted on the fixed shaft, one end of the elastic member abuts against the end surface of the rotating shaft away from the power unit, and the other end abuts against the inner wall of the delivery cavity.

[0030] Further, the power unit is arranged between the first delivery unit and the second delivery unit, and the two ends of the output shaft extend from the main body of the power unit respectively, one end of which is connected to the rotating member of the first delivery unit through a first clutch mechanism, and the other end of which is connected to the second delivery unit through a second clutch mechanism;

[0031] Preferably, 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.

[0032] A clothes processing device comprises the above-mentioned placing device.

[0033] After adopting the above technical scheme, the present invention has the following beneficial effects compared with the prior art.

In the first dispensing unit, the volume of the enclosed space between the two elastic sheets in the dispensing cavity is continuously changed by utilizing the bending deformation of the elastic sheet, thereby being able to inhale / discharge the laundry treatment agent, thereby realizing the automatic dispensing function and having a simple structure.

[0035] In the present invention, the installation gaps reserved on the upper and lower sides of the elastic sheet are always kept consistent by setting the first positioning ring and the second positioning ring. Compared with the installation method in which the upper and lower sides of the elastic sheet are directly exposed to the inner wall of the delivery chamber, the problem of excessive contact interference or excessive gap between the upper and lower sides of the elastic sheet and the first cover or the first shell due to the installation tightness tolerance of the first cover and the first shell is avoided, thereby preventing excessive wear of the elastic sheet or leakage of the closed space that affects the delivery efficiency.

DETAILED DESCRIPTION

[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.

For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.

[0048] Embodiment 1

[0049] like Figures 1 to 5 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.

[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 delivery device further comprises a power unit 3. The power unit 3 is transmission-connected to the first delivery unit 1 through a first clutch mechanism 11, and is also transmission-connected to the second delivery unit 2 through a second clutch mechanism 12. The clutch state of the second clutch mechanism 12 is opposite to that of the first clutch mechanism 11.

[0052] More specifically, in this embodiment, the power unit 3 controls the first delivery unit 1 and the second delivery unit 2 by outputting torque, and when the power unit 3 changes the output direction of the torque, the clutch state of the first clutch mechanism 11 and the second clutch mechanism 12 can be switched.

[0053] It can be understood that the above-mentioned clutch state means oppositely that: when the first clutch mechanism 11 is in the engaged state, that is, the power unit 3 can transmit torque through the first clutch mechanism 11, the second clutch mechanism 12 is in the disengaged state, that is, the power unit 3 cannot transmit torque through the second clutch mechanism 12, and vice versa.

[0054] In this embodiment, the dispensing device has the above structure, which realizes that the same power unit 3 changes the torque output direction, and can control one of the first dispensing unit 1 and the second dispensing unit 2 to perform the dispensing operation. Compared with the method of setting multiple dispensing pumps to control the dispensing of different types of clothing treatment agents in the prior art, the solution of this embodiment reduces the number of drive devices, makes the control simpler, and helps to reduce costs.

[0055] In a further solution of this embodiment, the first dispensing unit 1 includes a dispensing cavity, and the dispensing cavity is connected to a first liquid inlet 111 and a first liquid outlet 112. When the dispensing device is working, the clothes treating agent can be sucked in through the first liquid inlet 111, and then discharged from the dispensing cavity through the first liquid outlet 112, thereby achieving the dispensing of the clothes treating agent.

[0056] In order to realize the delivery function of the first delivery unit 1, the first delivery unit 1 also includes a rotating member and at least two elastic sheets 440 that can be bent and deformed. Among them, the rotating member is rotatably arranged inside the delivery chamber, and is connected to the power unit 3 through the first clutch mechanism 11. The rotating member includes a rotating shaft 410 arranged parallel to the axis of the delivery chamber. The elastic sheet 440 is extended from the side wall of the rotating shaft 410 to the periphery, the starting end is fixedly connected to the side wall of the rotating shaft 410, and the extended end is slidably against the side wall of the delivery chamber. The delivery chamber has a circular cross-section, and the axis of the rotating shaft 410 is eccentrically arranged with the axis of the delivery chamber.

[0057] The first delivery unit 1 has the above structure, when the torque output by the power unit 3 is transmitted to the rotating member through the first clutch mechanism 11, thereby driving the rotating shaft 410 to rotate in the delivery chamber, the end of the elastic sheet 440 connected to the side wall of the rotating shaft 410 can be driven to rotate accordingly. However, since the axis of the rotating shaft 410 does not coincide with the axis of the delivery chamber, the spacing distance between the side wall of the rotating shaft 410 and the side wall of the delivery chamber changes continuously along the circumferential direction, and the elastic sheet 440 is constrained by the side wall of the delivery chamber to bend and deform during the process of rotating with the rotating shaft 410.

[0058] Specifically, due to the friction between the ends of the elastic sheets 440 and the inner wall of the delivery cavity, each elastic sheet 440 is convexly bent along the rotation direction of the rotating shaft 410. Figure 3 , the rotating shaft 410 rotates counterclockwise in the delivery cavity, and at this time, the elastic sheet 440 bulges and bends in the counterclockwise direction.

[0059] Furthermore, the first liquid inlet 111 and the first liquid outlet 112 are centrally symmetrically arranged relative to the axis of the delivery chamber, and one end of two or more elastic sheets 440 close to the center is evenly spaced and connected to the side wall of the rotating shaft 410 along the circumferential direction. In this way, as the rotating shaft 410 rotates, the volume of the closed space formed by the two adjacent elastic sheets 440 and the inner wall of the delivery chamber changes continuously, and then the clothes treating agent is sucked from the first liquid inlet 111 through the volume change of the closed space, and then discharged from the first liquid outlet 112, so that quantitative addition of the clothes treating agent can be achieved.

[0060] In this embodiment, the number of elastic sheets 440 can be selected as needed. Figure 3 As shown, two elastic sheets 440 are provided and connected to the side walls of the rotating shaft 410 in opposite directions. The elastic sheets 440 may be made of rubber, silicone or polyurethane.

[0061] In this embodiment, the initial length of the elastic sheet 440 needs to be greater than or equal to the maximum distance between the side wall of the rotating shaft 410 and the inner surface of the side wall of the delivery cavity, so as to ensure that the extended end of the elastic sheet 440 always remains in contact with the side wall of the delivery cavity during the rotation of the rotating shaft 410.

[0062] Preferably, the initial length of the elastic sheet 440 is greater than or equal to the maximum distance between the side wall of the rotating shaft 410 and the inner surface of the side wall of the delivery chamber, so as to avoid the elastic sheet 440 failing to return to its original state in time and detaching from the side wall of the delivery chamber when the elastic sheet 440 rotates with the rotating shaft 410 to the maximum distance.

[0063] It can be understood that the initial length of the elastic sheet 440 mentioned above refers to the length that the elastic sheet 440 can reach when extending along a straight line without being subjected to external forces.

[0064] In a further solution of this embodiment, a first positioning ring 511 and a second positioning ring 512 are fixedly arranged around the inside of the delivery cavity. The first positioning ring 511 is arranged on a side of the delivery cavity close to the power unit 3, the second positioning ring 512 is arranged on a side of the delivery cavity away from the power unit 3, and the elastic sheet 440 is arranged between the first positioning ring 511 and the second positioning ring 512. That is, the first positioning ring 511 is located at the lower side of the elastic sheet 440, and the second positioning ring 512 is located at the upper side of the elastic sheet 440.

[0065] The spacing between the first positioning ring 511 and the second positioning ring 512 is close to the width of the elastic sheet 440 along the axial direction of the rotating shaft 410. Preferably, the spacing is slightly larger than the width of the elastic sheet 440. The first positioning ring 511 and the second positioning ring 512 cooperate to limit the extended end of the elastic sheet 440 in the vertical direction, thereby preventing the elastic sheet 440 from irregularly deforming and affecting the delivery effect.

[0066] Furthermore, the first delivery unit 1 described in this embodiment further includes a first shell 110 and a first cover 131. The first shell 110 has an opening on the side facing away from the power unit 3, and the first cover 131 is buckled on the opening of the first shell 110 to form a delivery cavity of the first delivery unit 1. The first positioning ring 511 and the second positioning ring 512 are fixed on the inner surface of the side wall of the first shell 110.

[0067] Since the first shell 110 and the first cover 131 are separately arranged, during the assembly process, due to the installation tightness tolerance between the first cover 131 and the first shell 110, there will be a certain fluctuation in the distance between the bottom wall of the first shell 110 and the inner surface of the first cover 131. The elastic sheet 440 needs to cooperate with the delivery cavity to form a closed space, so the height of the installation space reserved for the elastic sheet 440 in the delivery cavity needs to match the width of the elastic sheet 440. If the elastic sheet 440 is directly installed between the first shell 110 and the first cover 131, the contact interference or gap between the elastic sheet 440 and the inner surface of the first cover 131 or the bottom wall of the first shell 110 may be too large due to the installation tightness tolerance between the first cover 131 and the first shell 110.

[0068] If the interference is too large, the friction force on the upper and lower sides of the elastic sheet 440 will increase. On the one hand, it is easy to cause excessive wear of the elastic sheet 440, and then the closed space cannot be formed, resulting in failure of the delivery device. On the other hand, the increased friction force on the elastic sheet 440 will increase the rotation resistance of the rotating shaft 410, which may cause the motor 310 of the power unit 3 to stall.

[0069] If the gap between the upper and lower sides of the elastic sheet 440 is too large, it will cause air pressure leakage in the closed space formed between two adjacent elastic sheets 440, thereby affecting the efficiency of sucking / discharging the clothing treatment agent and reducing the dispensing efficiency of the dispensing device.

[0070] In the solution of this embodiment, the first positioning ring 511 and the second positioning ring 512 are fixedly installed on the inner surface of the side wall of the first housing 110, and the distance between the two is fixed, which is not affected by the tightness of the installation of the first cover 131 and the first housing 110. The elastic sheet 440 is arranged between the first positioning ring 511 and the second positioning ring 512, so that the installation gaps reserved on the upper and lower sides of the elastic sheet 440 are always consistent, avoiding the problems caused by the above-mentioned interference or excessive gap.

[0071] It should be noted that since the dispensing device of this embodiment is used to dispense clothing treatment agents, and general clothing treatment agents have a certain viscosity and cannot quickly pass through a very small gap, the upper and lower sides of the elastic sheet 440 do not need to be strictly sealed, and a small gap does not affect the dispensing of clothing treatment agents.

[0072] In a further solution of this embodiment, the rotating member further comprises a rotating shaft base 420, which is formed by extending the side wall of the rotating shaft 410 toward the periphery at one end of the rotating shaft 410 close to the power unit 3. The rotating member is supported in the delivery cavity by the rotating shaft base 420, and the structure is more stable.

[0073] Furthermore, an axial hole 411 is provided on the rotating shaft 410, and the axial hole 411 extends a certain length along the axial direction of the rotating shaft 410. A fixed shaft 520 coaxial with the rotating shaft 410 is fixedly provided in the delivery cavity, and the fixed shaft 520 is relatively rotatably inserted into the axial hole 411. Specifically, the upper end of the axial hole 411 is open, and the upper end of the fixed shaft 520 is connected to the first cover body 131 and inserted downward into the axial hole 411.

[0074] By providing the fixed shaft 520 , the rotating shaft 410 is sleeved on the fixed shaft 520 , and the axis position of the rotating shaft 410 is fixed, which neither affects the rotation of the rotating member in the delivery cavity nor makes the position of the rotating member more stable.

[0075] In this embodiment, the axis of the first positioning ring 511 coincides with the axis of the delivery cavity, that is, the rotation axis of the rotating shaft 410 and the rotating shaft base 420 are eccentrically arranged relative to the first positioning ring 511. Furthermore, in order to ensure that the rotating shaft base 420 can rotate, the rotating shaft base 420 itself cannot cover the hollow area inside the first positioning ring 511.

[0076] To this end, a filling piece 430 is further provided in the delivery cavity, and the filling piece 430 fills the interval area between the outer periphery of the rotating shaft base 420 and the inner peripheral wall of the first positioning ring 511. Specifically, the outer peripheral contour of the filling piece 430 is circular, so that the outer peripheral side wall of the filling piece 430 is arranged in close contact with the inner peripheral wall of the first positioning ring 511. The outer peripheral contour of the rotating shaft base 420 is circular, and the middle part of the filling piece 430 has an eccentrically arranged circular hole, and the rotating shaft base 420 is embedded in the circular hole, and the rotating shaft base 420 and the filling piece 430 can rotate relative to each other.

[0077] In the preferred solution of this embodiment, the first positioning ring 511, the rotating shaft base 420 and the filling member 430 have the same size along the axial direction of the rotating shaft 410. That is to say, when the rotating member is installed in the delivery cavity of the first delivery unit 1, the upper surfaces of the first positioning ring 511, the rotating shaft base 420 and the filling member 430 are flush. In this way, the lower side of the elastic sheet 440 is spaced at the same distance from the lower structure within its entire extension range, so that the closed space formed between two adjacent elastic sheets 440 is not prone to air pressure leakage.

[0078] In this embodiment, the power unit 3 is arranged below the first delivery unit 1, and includes a motor 310 having an output shaft 311. A through hole is provided on the bottom wall of the first housing 110, and the upper end of the output shaft 311 is inserted through the through hole, thereby contacting and transmitting with the rotating member.

[0079] Furthermore, a shaft seal 312 is provided between the output shaft 311 and the through hole on the bottom wall of the first housing 110 to prevent the laundry treatment agent from leaking out of the through hole on the bottom wall of the first housing 110. In order to further enhance the sealing performance of the delivery chamber, a dynamic seal may also be provided between the rotating shaft base 420 and the bottom wall of the first housing 110.

[0080] Similarly, the connection between the first cover 131 and the first shell 110 can also be sealed by providing a seal. Alternatively, the first cover 131 and the first shell 110 are connected by ultrasonic welding or cladding to achieve sealing between the two.

[0081] In a further solution of this embodiment, the power unit 3 is arranged between the first delivery unit 1 and the second delivery unit 2, and the two ends of the output shaft 311 extend from the main body of the power unit 3, that is, from the inside of the motor 310. The upper end of the output shaft 311 is connected to the rotating part of the first delivery unit 1 through the first clutch mechanism 11, and the lower end is connected to the second delivery unit 2 through the second clutch mechanism 12.

[0082] In this embodiment, the second dispensing unit 2 may have the same structure as the first dispensing unit 1. That is, a rotating member is also provided in the dispensing cavity of the second dispensing unit 2, and the rotating member includes a rotating shaft 410 eccentric to the axis of the dispensing cavity, and at least two elastic sheets 440 are connected to the rotating shaft 410. By driving the rotating member to rotate, the elastic sheets 440 can be bent and deformed, and the laundry treatment agent is sucked into the dispensing cavity of the second dispensing unit 2 from the second liquid inlet 121, and then discharged from the second liquid outlet 122 to achieve dispensing.

[0083] The second delivery unit 2 adopts the above structure, and the lower end of the output shaft 311 is transmission-connected with the rotating member inside its delivery chamber through the second clutch mechanism 12, thereby controlling the delivery process of the second delivery unit 2.

[0084] More specifically, the second delivery unit 2 is symmetrically arranged with the first delivery unit 1. The second delivery unit 2 includes a second housing 120 and a second cover 132. The lower side of the second housing 120 is open, and the second cover 132 is buckled with the second housing 120 from the lower side. The lower end of the output shaft 311 is inserted through the through hole on the second housing 120 and is in contact with the internal rotating member for transmission. A shaft seal 312 for sealing is also arranged between the lower end of the output shaft 311 and the through hole on the second housing 120.

[0085] In the second dispensing unit 2 , a fixed shaft 520 is also fixedly connected to the second cover 132 , and a shaft hole 411 with an opening at the lower end is provided on the rotating shaft 410 of the rotating member. The fixed shaft 520 is inserted upward into the shaft hole 411 to limit the rotating shaft 410 .

[0086] The first positioning ring 511 and the second positioning ring 512 are also fixed on the inner surface of the side wall of the second housing 120. Different from the first delivery unit 1, in the second delivery unit 2, the first positioning ring 511 is located on the upper side of the elastic sheet 440, and the second positioning ring 512 is located on the lower side of the elastic sheet 440.

[0087] When the dispensing device described in this embodiment 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.

[0088] 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 output shaft 311 of the power unit 3 rotates counterclockwise, 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. During the rinsing stage, the output shaft 311 of the power unit 3 rotates clockwise, 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.

[0089] During operation, the delivery device of this embodiment controls the output shaft 311 to move in the first direction (i.e. Figure 4 The first clutch mechanism 11 is in a coupled state, and the rotating member in the delivery chamber of the first delivery unit 1 is driven to rotate, thereby driving the elastic sheet 440 connected to the rotating shaft 410 to rotate accordingly, and generating bending deformation under the constraint of the side wall of the delivery chamber, and then the clothing treatment agent is sucked from the first liquid inlet 111 through the continuous change of the volume of the several closed spaces in the delivery chamber, and then discharged from the first liquid outlet 112, so that the first delivery unit 1 performs the delivery operation. At this time, the second clutch mechanism 12 is in a disengaged state, and the rotating member in its delivery chamber does not rotate, and then the second delivery unit 2 does not deliver.

[0090] When the output shaft 311 is controlled to move in a second direction opposite to the first direction (i.e. Figure 5When the first dispensing unit 1 rotates clockwise (in the middle), the first clutch mechanism 11 switches to the disengaged state, and then the rotating member in the dispensing chamber of the first dispensing unit 1 does not rotate with the output shaft 311, and the first dispensing unit 1 does not perform dispensing at this time. On the contrary, the second clutch mechanism 12 switches to the engaged state, so that the output shaft 311 can drive the rotating member in the dispensing chamber of the second dispensing unit 2 to rotate, driving the elastic sheet 440 to rotate with the rotating shaft 410 and bend and deform, so that the laundry treatment agent is sucked from the second liquid inlet 121 and then discharged from the second liquid outlet 122, so that the second dispensing unit 2 performs the dispensing operation.

[0091] In this embodiment, the dispensing device uses the same power unit 3 to control the dispensing action of the two dispensing units. The first dispensing unit 1 and the second dispensing unit 2 both use the bending deformation of the elastic sheet 440 to form a closed space with a continuously changing volume, thereby completing the suction and discharge of the clothing treatment agent, thereby realizing the quantitative dispensing of the clothing treatment agent, and the structure is simple and easy to implement.

[0092] Embodiment 2

[0093] like Figures 1 to 5 As shown, this embodiment is a further limitation of the above-mentioned embodiment 1, and the rotating member is movably installed in the delivery chamber along the axial direction of the rotating shaft 410. When the output shaft 311 rotates in the first direction, the output shaft 311 is combined with the rotating member of the first delivery unit 1, driving the rotating member to rotate synchronously with the output shaft 311; and when the output shaft 311 rotates in the second direction, the output shaft 311 pushes the rotating member to separate from the output shaft 311 along the axial direction of the rotating shaft 410.

[0094] Specifically, the first clutch mechanism 11 of this embodiment includes an inclined groove formed on the surface of the rotating member close to the power unit 3, and a clamping portion formed on the end surface of the output shaft 311. Figure 4 When the output shaft 311 rotates in the second direction (i.e., counterclockwise), the engaging portion and the inclined slot limit position cooperate, thereby driving the rotating shaft 410 to rotate synchronously with the output shaft 311. Figure 5 When the rotating shaft 410 rotates in the counterclockwise direction, the engaging portion pushes the inclined slot axially along the rotating shaft 410 and slips off the inclined slot, so that the rotating shaft 410 does not rotate.

[0095] In the above scheme, the first clutch mechanism 11 is arranged on the lower surface of the rotating member and the upper end surface of the output shaft 311, without occupying the internal space of the delivery cavity of the first delivery unit 1, saving the installation space inside the delivery cavity, and effectively avoiding the first clutch mechanism 11 from interfering with the elastic sheet 440 in the delivery cavity for controlling delivery.

[0096] In this embodiment, the fixed shaft 520 connected to the first cover body 131 can be relatively slidably inserted into the shaft hole 411 on the rotating shaft 410, see Figure 5 When the output shaft 311 rotates clockwise, the rotating member can be pushed to move upward along the fixed shaft 520 , so that the first clutch mechanism 11 switches to a disengaged state, and the rotating shaft 410 does not rotate with the output shaft 311 .

[0097] As a specific implementation of this embodiment, the area on the lower surface of the rotating member opposite to the upper end surface of the output shaft 311 has two staggered, oppositely inclined inclined surfaces, for example, the two inclined surfaces are staggered back and forth, one inclined surface is inclined downward from the left side to the right side, and the other inclined surface is inclined downward from the right side to the left side, so that the inclined slot is formed along the intersection of the two inclined surfaces. The end surface of the output shaft 311 also has two similar inclined surfaces, and the engaging portion is a convex structure formed on the end surface of the output shaft 311 by the two oppositely inclined inclined surfaces.

[0098] More specifically, through the above structure, the lower surface of the rotating member and the upper end surface of the output shaft 311 can respectively form two matching planes along the same straight line but arranged opposite to each other and parallel to the axial direction of the output shaft 311 .

[0099] When the output shaft 311 rotates counterclockwise, the end face of the output shaft 311 engages with the area on the lower surface of the rotating member where two inclined surfaces are arranged, and the intersecting part of the two sets of oppositely inclined inclined surfaces is limitedly matched, so that the matching plane on the output shaft 311 can push the matching plane on the lower surface of the rotating member, thereby driving the rotating member to rotate synchronously. When the output shaft 311 rotates clockwise, the matching plane on the output shaft 311 rotates in a direction away from the matching plane on the rotating member, and at the same time pushes the rotating member upward along the inclined surface structure, so that the rotating member does not rotate with the output shaft 311.

[0100] Furthermore, in this embodiment, the closed end of the shaft hole 411 on the rotating shaft 410 (i.e. Figure 4 and Figure 5 There is a certain spacing distance between the lower end of the output shaft 311 and the end of the fixed shaft 520 inserted into the shaft hole 411, and the fixed shaft 520 can be relatively slidably inserted into the shaft hole 411. When the output shaft 311 rotates clockwise, the rotating member is pushed by the output shaft 311 and rises a certain height along the fixed shaft 520 under the limited cooperation between the fixed shaft 520 and the shaft hole 411.

[0101] In this way, it is ensured that when the first clutch mechanism 11 is in the disengaged state, the rotating member can only move in the vertical direction without deviation, ensuring that when the output shaft 311 stops rotating or rotates counterclockwise again, the rotating member can fall back to its original position.

[0102] In a further solution of this embodiment, in order to ensure that the rotating member can be smoothly reset after being pushed away from the output shaft 311, an elastic member 530 for resetting the rotating member is further provided in the delivery chamber. Specifically, the elastic member 530 is sleeved on the fixed shaft 520, one end of the elastic member 530 abuts against the end face of the rotating shaft 410 away from the power unit 3, and the other end abuts against the inner wall of the delivery chamber.

[0103] In detail, the elastic member 530 is a compression spring sleeved on the fixed shaft 520, with its upper end abutting against the lower surface of the first cover 131, and its lower end abutting against the area of ​​the upper end of the rotating shaft 410 located at the opening periphery of the shaft hole 411. When the output shaft 311 rotates clockwise and lifts the rotating member upward, the rotating shaft 410 moves upward to compress the elastic member 530. When the output shaft 311 rotates to the point where the highest point of the inclined surface structure on its end surface is just opposite to the lowest point of the inclined surface structure on the lower surface of the rotating member, the output shaft 311 rotates further to rotate the highest point of the inclined surface structure on the output shaft 311 to the highest point of the inclined surface structure on the lower surface of the rotating member, and at this time, the rotating member can fall and reset under the elastic force of the elastic member 530.

[0104] In the preferred solution of this embodiment, the outer peripheral side wall of the rotating shaft base 420 is inclined, and correspondingly, the inner wall of the circular hole in the middle of the filling piece 430 is inclined in the same direction as the outer peripheral side wall of the rotating shaft base 420. Due to the inclined cooperation between the outer peripheral side wall of the rotating shaft base 420 and the inner wall of the circular hole of the filling piece 430, when the rotating member moves up and down under the action of the output shaft 311, the filling piece 430 located on the outer periphery of the rotating shaft base 420 will also move up and down synchronously.

[0105] When the rotating member is lifted up, the end of the elastic sheet 440 connected to the rotating shaft 410 rises with the rotating shaft 410, but the other end of the elastic sheet 440 is stopped on the side wall of the delivery chamber and is subject to a certain friction force, and may not rise synchronously. Since the bottom of the rotating member has a rotating shaft base 420 located on the lower side of the elastic sheet 440, when the rotating member moves upward as a whole, the area of ​​the elastic sheet 440 located above the rotating shaft base 420 can also be lifted up by the rotating shaft base 420 and rise with it. However, the elastic sheet 440 also has a relatively long range located outside the rotating shaft base 420, which is not directly subject to the upward driving force, and thus it is easy to cause a certain degree of pulling on the elastic sheet 440.

[0106] The solution of this embodiment cooperates with the structure of the rotating shaft base 420 and the filling piece 430, so that the filling piece 430 can move up and down synchronously with the rotating shaft base 420. In this way, when the rotating member is pushed up, the area below the elastic sheet 440 that can push up the elastic sheet 440 synchronously is larger, that is, when the elastic sheet 440 rises with the rotating member, it can be supported by the structure below in a larger length range, reducing the pulling degree on both ends of the elastic sheet 440.

[0107] In this embodiment, the second clutch mechanism 12 can have the same structure as the first clutch mechanism 11, but the clutch state is opposite. That is, when the output shaft 311 rotates counterclockwise, the second clutch mechanism 12 is in a disengaged state, and the output shaft 311 pushes the rotating member in the second delivery unit 2 downward to prevent it from rotating. When the output shaft 311 rotates clockwise, the rotating member in the second delivery unit 2 contacts and cooperates with the lower end of the output shaft 311, and rotates synchronously with the output shaft 311.

[0108] The specific working process of the dispensing device described in this embodiment is as follows. When the first dispensing unit 1 is required to dispense, the output shaft 311 is controlled to rotate counterclockwise, and the first clutch mechanism 11 is in a coupled state. The output shaft 311 drives the rotating parts in the first dispensing unit 1 to rotate synchronously, and then the elastic sheet 440 connected to the rotating shaft 410 bends and deforms with the rotation, and the clothing treatment agent is sucked from the first liquid inlet 111 and then discharged from the first liquid outlet 112, thereby realizing the dispensing operation of the first dispensing unit 1. At the same time, the second clutch mechanism 12 is in a disengaged state, and the rotation of the output shaft 311 pushes the rotating parts of the second dispensing unit 2 downward to separate from it, so that the second dispensing unit 2 does not dispense.

[0109] When the second dispensing unit 2 is required to dispense, the output shaft 311 is controlled to rotate clockwise, at which time the first clutch mechanism 11 is in a disengaged state, the output shaft 311 pushes the rotating part of the first dispensing unit 1 upwards and separates it, and the first dispensing unit 1 does not dispense. At this time, the second clutch mechanism 12 is in a coupled state, the output shaft 311 drives the rotating part of the second dispensing unit 2 to rotate synchronously, and then the elastic sheet 440 in the dispensing cavity is elastically deformed as the rotating shaft 410 rotates, and the volume change of the closed space is used to suck the laundry treatment agent from the second liquid inlet 121 and discharge it from the second liquid outlet 122, thereby realizing the dispensing operation of the second dispensing unit 2.
