Description

Technical Field

[0001] The present application relates to the field of treatment agent delivery, and in particular to a treatment agent delivery device and a washing device. Background Art

[0002] In the related art, washing equipment often needs to add treatment agents during the washing process. Taking washing machines as an example, it is necessary to add treatment agents such as laundry detergent and softener. Since manual addition of treatment agents requires additional operations and it is difficult to accurately grasp the amount and timing of addition, washing machines with automatic addition functions are becoming more and more popular. Most of the related automatic addition devices use electric-driven peristaltic pumps, gear pumps, piston pumps and other pump bodies to extract treatment agents to achieve automatic addition. In this way, an additional electric drive device needs to be set up, which increases the hardware cost and makes it difficult to widely promote and apply washing machines with automatic addition functions. In addition, the treatment agent delivery channel is often blocked due to the condensation of residual treatment agents, which brings great inconvenience to automatic delivery.

[0081] In order to make the purpose, technical solutions and advantages of the present application clearer, the present application will be further described in detail below in conjunction with the accompanying drawings. The described embodiments should not be regarded as limiting the present application. All other embodiments obtained by ordinary technicians in the field without making creative work are within the scope of protection of this application.

[0082] In the description of the present application, reference is made to “some embodiments”, which describe a subset of all possible embodiments, but it can be understood that “some embodiments” may be the same subset or different subsets of all possible embodiments and may be combined with each other without conflict.

[0083] In the description of the present application, the terms "first, second" and the like are only used to distinguish similar objects and do not represent a specific order of the objects. It is understandable that "first, second" and the like can be interchanged with a specific order or sequence where permitted, so that the embodiments of the present application described herein can be implemented in an order other than that illustrated or described herein. Unless otherwise specified, "plurality" means at least two.

[0085] In the description of this application, 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 direct connection, or an indirect connection through an intermediate medium, or it can be the internal communication of two components. For ordinary technicians in this field, the specific meanings of the above terms in this application can be understood according to specific circumstances.

[0086] In the present application, unless otherwise clearly specified and limited, a first feature being "above" or "below" a second feature may include that the first and second features are in direct contact, or may include that the first and second features are not in direct contact but are in contact through another feature between them.

A first feature being "below", "below" and "below" a second feature includes that the first feature is directly below and obliquely below the second feature, or simply indicates that the first feature is lower in level than the second feature.

[0087] The present application provides a treatment agent delivery device, which can use water flow as a power source to achieve automatic delivery of the treatment agent. Figure 1 As shown, the treatment agent delivery device includes: a first chamber 1A, a rotating mechanism 2, a delivery mechanism and a cleaning mechanism. Among them, the first chamber 1A has a water inlet 1011, so that water flows into the first chamber 1A. The rotating mechanism 2 is arranged in the first chamber 1A, and is used to rotate under the drive of the water flow introduced by the water inlet 1011. The delivery mechanism is connected to the rotating mechanism 2, and the power output by the rotating mechanism 2 is transmitted to the delivery mechanism to drive the delivery mechanism to move, thereby eliminating the electric drive device and saving costs. The outlet of the cleaning mechanism is connected to the delivery mechanism for conveying cleaning agent into the delivery mechanism. Here, the cleaning agent can be water for cleaning the delivery channel or other liquids with a cleaning function. Thereby, the delivery mechanism delivers the cleaning agent under the drive of the water flow, automatically cleans the delivery channel, effectively avoids the blockage caused by the condensation of the treatment agent in the delivery channel, and improves the intelligence level of the treatment agent delivery device.

[0088] In some embodiments, the cleaning mechanism includes a control valve 5, which includes: an output port 503, which is connected to a delivery mechanism; the rotating mechanism 2 rotates under the drive of the water flow introduced by the water inlet 1011, and the power output by the rotating mechanism 2 is transmitted to the delivery mechanism after being decelerated and torque-increased by the reduction mechanism 4. At the same time, under the control of the control valve 5, the output port 503 inputs the cleaning agent into the delivery mechanism, so that the delivery mechanism can input the cleaning agent based on the output port 503 of the control valve 5 and deliver it as needed, thereby achieving the effect of automatically and on-demand delivery of the cleaning agent driven by water flow, thereby improving the intelligence level of the treatment agent delivery device.

[0089] In some embodiments, the control valve 5 also includes: a first input port 501 and a second input port 502, wherein when the first input port 501 is connected to the output port 503, the output port 503 supplies cleaning agent to the dispensing mechanism; when the second input port 502 is connected to the output port 503, the output port 503 supplies treatment agent to the dispensing mechanism.

[0090] In practical applications, the treatment agent delivery device is often prone to blockage of the delivery channel due to the condensation of the treatment agent, resulting in high maintenance costs. In the embodiment of the present application, based on the control valve 5, the first input port 501 is controlled to be connected with the output port 503, and the output port 503 conveys the cleaning agent into the delivery mechanism, and the delivery channel can be automatically cleaned by the delivery mechanism. Based on the control valve 5, the second input port 502 is controlled to be connected with the output port 503, and the output port 503 conveys the treatment agent into the delivery mechanism, and the treatment agent can be automatically delivered through the delivery mechanism. In this way, the delivery channel blockage caused by the condensation of the treatment agent can be effectively avoided, thereby achieving the effect of automatic cleaning of the delivery channel and avoiding residues in the delivery process of the treatment agent, and the treatment agent can be automatically delivered by the delivery mechanism, so that the switch between delivering the treatment agent and cleaning the delivery channel can be realized, and the delivery channel can be cleaned as needed.

[0091] It is understandable that the water flow entering the water inlet 1011 drives the rotating mechanism 2 to rotate, and the rotating mechanism 2 drives the delivery mechanism to move under the action of the water flow. When the first input port 501 of the control valve 5 is connected to the output port 503, the output port 503 supplies the cleaning agent to the delivery mechanism, and the water at the output port 503 can be delivered to the delivery channel by the delivery mechanism, thereby cleaning the delivery channel. When the second input port 502 of the control valve 5 is connected to the output port 503, the output port 503 supplies the treatment agent to the delivery mechanism, and the treatment agent at the output port 503 can be delivered to the delivery channel by the delivery mechanism, thereby realizing the automatic delivery of the treatment agent. In this way, the treatment agent delivery device can not only use the water flow as a power source to realize the automatic delivery of the treatment agent, but also save the electric pump body, thereby saving costs; it can also use the water flow to flush the delivery channel, effectively avoiding the blockage of the delivery channel caused by the condensation of the treatment agent. Here, the treatment agent can be a liquid or powdered washing product required for washing, and those skilled in the art can make a reasonable choice according to the needs, and this application does not make specific restrictions on this.

[0092] Here, the control valve 5 can be a solenoid valve or a mechanical valve body. Taking the solenoid valve as an example, its opening and closing state can be controlled by a program after each treatment agent is added to achieve automatic cleaning. Taking the mechanical valve body as an example, the user can manually control the working state of the valve body to achieve a number of cleaning functions at any time.

[0093] In some embodiments, Figure 1 As shown, the first chamber 1A further includes a water outlet 1012, and the first input port 501 is connected to the water outlet 1012, so that the delivery channel can be cleaned with water flowing out of the first chamber 1A to simplify the setting of the water supply pipeline.

[0094] In some embodiments, Figure 2 As shown, the first input port 501 is connected to the water supply port 1016, so that the delivery channel can be cleaned with water supplied solely by the water supply port 1016.

[0095] In some embodiments, Figure 1 and Figure 2 As shown, the delivery mechanism includes: a speed reduction mechanism 4 and a distribution mechanism 3, wherein the input end of the speed reduction mechanism 4 is connected to the rotating mechanism 2, and the distribution mechanism 3 is connected to the output end of the speed reduction mechanism 4. The power output by the rotating mechanism 2 is decelerated and torque-increased by the speed reduction mechanism, and the torque-increased power is transmitted to the distribution mechanism 3, and the distribution mechanism 3 drives the delivery of different reagents (water or treatment agent) at the output port 503.

[0096] It should be noted that, since the water pressure of the water flow may fluctuate during use, in the embodiment of the present application, the output power of the rotating mechanism 2 is transmitted to the dispensing mechanism 3 after being decelerated and torque-increased by the speed reduction mechanism 4, which can effectively widen the working range of the water flow pressure, so that after the water flow under low water pressure drives the rotating mechanism 2, the speed reduction mechanism 4 decelerates and increases the torque, thereby increasing the torque output by the dispensing mechanism 3, which is conducive to the automatic delivery of the treatment agent or the cleaning of the delivery channel, thereby improving the reliability of the treatment agent delivery device.

[0097] It is understandable that the rotating mechanism 2 can be an impeller driven by water flow, such as a turbine or a propeller. The rotating mechanism 2 can rotate under the action of the water flow in the first chamber 1A to output power, and this application does not make any specific restrictions on this.

[0098] In some embodiments, the water outlet 1012 and the water inlet 1011 of the first chamber 1A are arranged opposite to each other or perpendicular to each other, and this application does not make any specific limitation on this.

[0099] In some embodiments, Figure 1 and Figure 3 As shown, the rotating mechanism 2 includes an impeller 21, the rotating shaft of the impeller 21 is vertically arranged in the first chamber 1A, the water inlet 1011 and the water outlet 1012 are respectively arranged on both sides of the impeller 21, and the water flow enters through the water inlet 1011 to drive the impeller 21 to rotate; the rotating shaft of the impeller 21 is connected to the input end of the reduction mechanism 4. In this way, the impeller 21 can rotate under the drive of the water flow, thereby converting the water energy into mechanical energy. Here, the impeller 21 includes a plurality of first blades 211 fixed on the output shaft, and the first blades 211 can be curved blades or straight blades, wherein the straight blade refers to a blade whose surface is planar, so as to rotate under the drive of the water flow; the curved blade refers to a blade whose surface is curved, so that the blade has a set curvature, which is conducive to the formation of a rotating vortex.

[0100] For example, Figure 1 As shown, the treatment agent delivery device includes: a shell 1, in which a first chamber 1A and a second chamber 1C are formed which are spaced apart from each other. For example, the shell 1 includes an outer shell 101 and a first end cover 102, and the first end cover 102 cooperates with the outer shell 101 to form the first chamber 1A. The shell 1 also includes a second end cover 103, and the second end cover 103 cooperates with the outer shell 101 to form the second chamber 1C. The distribution mechanism 3 can be arranged in the second chamber 1C. The water inlet 1011 and the water outlet 1012 are respectively arranged on both sides of the outer shell 101, and the external water source enters the first chamber 1A through the water inlet 1011, flows out through the water outlet 1012, and drives the rotating mechanism 2 to rotate. For example, the direction of the water flow is along Figure 3 As shown by the arrow, the impeller 21 located in the first chamber 1A rotates counterclockwise under the pressure of the water flow.

[0101] It is understandable that the reduction mechanism 4 may include but is not limited to: a gear reducer, a worm gear reducer or a planetary reducer, as long as it can convert the power output by the water flow-driven rotating mechanism 2 into a larger output torque, and this application does not make specific limitations on this.

[0102] In some embodiments, a third chamber 1B for accommodating the speed reduction mechanism 4 is formed in the housing 101, and the third chamber 1B is located between the first chamber 1A and the second chamber 1C. It is understood that in other embodiments, the speed reduction mechanism 4 can also be disposed in the second chamber 1C, thereby making the structure more compact.

[0103] For example, Figure 1 and Figure 4 As shown, the reduction mechanism 4 includes: a power shaft 401, a planetary gear 402, a planetary carrier 403 and a ring gear 404, wherein the power shaft 401 is connected to the rotating mechanism 2 and driven by the rotating mechanism 2; the ring gear 404 is fixed on the housing 101, and it can be understood that the ring gear 404 can be a separately arranged annular member, and the inner wall of the annular member is provided with internal teeth, and the annular member is fixed in the third chamber 1B, or the ring gear 404 with an annular inner tooth surface is machined on the inner wall of the third chamber 1B; the planetary gear 402 is arranged between the power shaft 401 and the ring gear 404, and is meshed with the power shaft 401 and the ring gear 404; the planetary carrier 403 is connected to the planetary gear 402, and outputs power to the distribution mechanism 3 under the drive of the planetary gear 402. It can be understood that the first end 401A of the power shaft 401 can extend into the first chamber 1A and be fixedly connected to the rotating mechanism 2, and the second end 401B of the power shaft 401 is provided with external teeth meshing with the planetary gear 402, serving as the sun gear of the planetary reducer. The planet carrier 403 can have an end 403A extending into the second chamber 1C, and the end 403A is used to drive the dispensing mechanism 3 located in the second chamber 1C.

[0104] In some embodiments, the reduction ratio of the reduction mechanism 4 is 30 to 150: 1. Thus, the treatment agent delivery device can work normally within the water pressure range of 0.03 MPa to 1.0 MPa, so that the treatment agent delivery device has a wide range of application prospects, for example, it can be applied to household appliances such as washing machines or dishwashers.

[0105] In some embodiments, the dispensing mechanism 3 includes a pump body. Exemplarily, the pump body is disposed in the second chamber 1C, and the first chamber 1C has a liquid inlet 1013 and a liquid outlet 1014, the liquid inlet 1013 is connected to the output port 503, the inlet of the pump body is connected to the liquid inlet 1013, and the outlet of the pump body is connected to the liquid outlet 1014, and the liquid is delivered to the working chamber of the washing device through the liquid outlet 1014. The pump body can be at least one of a plunger pump, a vane pump, and a diaphragm pump. The pump body can work under the torque-increased power output by the speed reduction mechanism 4, for example, the input shaft of the pump body can be connected to Figure 1 End 403A of planet carrier 403 is shown.

[0106] In some embodiments, Figure 5 As shown, the dispensing mechanism 3 includes: a main body 301, a second blade 302 and an elastic member 303; the main body 301 is eccentrically arranged in the second chamber 1C and connected to the output end of the reduction mechanism 4 (such as the end 403A of the planetary carrier 403). Specifically, there is an eccentric distance between the center of the main body 301 and the center of the second chamber 1C. The main body 301 can rotate around the center of the main body 301 in the second chamber 1C under the drive of the reduction mechanism 4, that is, it rotates eccentrically relative to the second chamber 1C. A plurality of radially arranged grooves 3011 are provided on the main body 301; the second blade 302 is installed in the groove 3011 via the elastic member 303. The main body 301 rotates in the second chamber 1C (such as along the Figure 5 (as shown in the clockwise rotation direction), under the action of the elastic member 303, the second blade 302 disposed in the groove 3011 extends outward along the groove 3011 to seal with the inner wall surface 1015 of the second chamber 1C formed on the housing 101, so that a sealing area is formed between two adjacent second blades 302, wherein, since the body 301 is eccentrically disposed in the second chamber 1C, a sealing area with a variable volume can be formed between the two second blades 302, the body 301 and the inner wall surface 1015. Figure 5 As shown, when the body 301 rotates clockwise, the volume of the sealing area corresponding to the liquid inlet 1013 changes from small to large, so that the pressure in the sealing area decreases, and the treatment agent or water is sucked into the sealing area through the liquid inlet 1013, and when the sealing area rotates to the liquid outlet 1014, the volume changes from large to small, so that the pressure in the sealing area increases, and the treatment agent or water in the sealing area is discharged through the liquid outlet 1014 under the action of pressure, thereby achieving extraction and discharge of the treatment agent or water. Specifically, the second blades 302 and the elastic member 303 are arranged one by one with the grooves 3011, so as to form a sealing area between adjacent second blades 302.

[0107] Taking the treatment agent delivery as an example, the specific delivery process of the treatment agent delivery performed by the dispensing mechanism 3 is as follows:

[0108] The second input port 502 of the control valve 5 is connected to the output port 503, and the external water flows into the first chamber 1A through the water inlet 1011 and flows out from the water outlet 1012. The impeller 21 rotates driven by the water flow, and the rotational kinetic energy generated by the rotation of the impeller 21 is transmitted to the speed reduction mechanism 4 through the power shaft 401, and the speed reduction mechanism 4 drives the body 301 to rotate after deceleration and torque increase. When the body 301 rotates, the second blade 302 will be close to the inner wall surface 1015 of the shell 101 under the action of centrifugal force and the elastic force of the elastic member 303. In this way, a working volume of varying size is formed between the two second blades 302, the body 301 and the inner wall surface 1015. The working volume absorbs the treatment agent from small to large, and then discharges the treatment agent from large to small. The body 301 rotates one circle to complete the absorption and discharge of the treatment agent. The process of cleaning the delivery channel of the treatment agent automatic delivery device is similar to the above process. It only needs to make the first input port 501 of the control valve 5 connected to the output port 503, which will not be repeated here.

[0109] In some embodiments, Figure 6 and Figure 7 As shown, the dispensing mechanism 3 can also be a pump body that moves back and forth under the drive of the speed reduction mechanism 4, and the dispensing mechanism 3 includes: a pump housing 304, a first one-way valve 305, a second one-way valve 306 and a crank slider mechanism 308, wherein a pump cavity 307 is formed in the pump housing 304, and the pump cavity 307 is connected to the liquid inlet 1013 through the first one-way valve 305, and the treatment agent or water can enter the pump cavity 307 unidirectionally through the liquid inlet 1013 and the first one-way valve 305; the pump cavity 307 is connected to the liquid outlet 1014 through the second one-way valve 306, and the treatment agent or water in the pump cavity 307 can be discharged unidirectionally through the second one-way valve 306 and the liquid outlet 1014. The crank slider mechanism 308 can convert the circumferential motion into the linear reciprocating motion under the drive of the output end of the speed reduction mechanism 4, so that the slider matched with the pump cavity 307 moves back and forth along the inner wall surface of the pump cavity 307, so as to drive the treatment agent or water to enter unidirectionally through the liquid inlet 1013 and the first one-way valve 305, and to be discharged unidirectionally through the second one-way valve 306 and the liquid outlet 1014. Among them, the crank slider mechanism 308 refers to a planar connecting rod mechanism that uses a crank and a slider to realize the mutual conversion between rotation and movement, and the specific structure is not repeated here.

[0110] In this way, the dispensing mechanism 3 in the embodiment of the present application can not only be a rotating mechanism driven by the reduction mechanism 4, but also a mechanism that converts the output of the reduction mechanism 4 into a linear reciprocating displacement. Technical personnel in this field can make a reasonable design according to needs to achieve automatic delivery of the treatment agent.

[0111] In some embodiments, the number of dispensing mechanisms 3 in the treatment agent delivery device can also be two or more, for example, Figure 8As shown, the treatment agent delivery device includes: a first dispensing mechanism 3A and a second dispensing mechanism 3B.

[0112] Combine the following Figures 8 to 12 , the structure of the treatment agent delivery device with a dual dispensing mechanism is illustrated by way of example.

[0113] like Figure 8 As shown, the treatment agent delivery device includes: a first chamber 1A, a second chamber 1C, a rotating mechanism 2, a speed reduction mechanism 4, a power distribution mechanism 6, a first distribution mechanism 3A and a second distribution mechanism 3B. Exemplarily, the treatment agent delivery device includes: a housing 1, in which a first chamber 1A and a second chamber 1C are formed and spaced from each other. The first water inlet 1011A and the second water inlet 1011B are located on the first side of the housing 1, and the water outlet 1012 is located on the second side of the housing 1.

[0114] like Fig. 9 As shown, the housing 1 includes a shell 101 and a first end cover 102, and the first end cover 102 cooperates with the shell 101 to form a first chamber 1A. The first chamber 1A is generally formed as a cylindrical chamber, and the first side of the first chamber 1A extends outward to form a first water inlet pipe 1020 and a second water inlet pipe 1021, which are arranged in parallel and are respectively located at the upper and lower ends of the first chamber 1A, and the second side of the first chamber 1A extends outward to form a water outlet pipe 1022, and the water outlet pipe 1022 is located in the middle of the first chamber 1A.

[0115] Exemplarily, the inlet of the first water inlet pipe 1020 forms a first water inlet 1011A, the inlet of the second water inlet pipe 1021 forms a second water inlet 1011B, and the outlet of the water outlet pipe 1022 forms a water outlet 1012; when water flows in from the first water inlet 1011A, the rotating mechanism 2 is driven to rotate in the clockwise direction; when water flows in from the second water inlet 1011B, the rotating mechanism 2 is driven to rotate in the counterclockwise direction; if water flows into the first water inlet 1011A and the second water inlet 1011B at similar flow rates at the same time, the power of the rotating mechanism 2 cancels each other, that is, it can maintain a stationary state, but the water can flow out normally from the water outlet 1012. In this way, by switching the water supply state, the rotating mechanism 2 in the first chamber 1A can rotate in the clockwise direction, rotate in the counterclockwise direction, or stop when the pressures are offset and maintain normal water supply under the pressure of the water flow.

[0116] Exemplarily, the rotating mechanism 2 includes an impeller 21, the rotating axis of the impeller 21 is vertically arranged in the chamber 1A, and the first water inlet 1011A and the second water inlet 1011B are located on one side of the impeller 21 (such as Fig. 9 The water outlet 1012 is located on the other side of the impeller 21 (as shown in FIG. Fig. 9As shown in the right side, water flows into the impeller 21 through the first water inlet 1011A or the second water inlet 1011B, and then flows out through the water outlet 1012; the rotating shaft of the impeller 21 is connected to the input end of the speed reduction mechanism 4. In this way, the impeller 21 can rotate under the drive of the water flow, thereby converting the water energy into mechanical energy.

[0117] For example, Figure 8 and Fig.10 As shown, the speed reduction mechanism 4 includes: a power shaft 401, a first speed reduction gear 405, a second speed reduction gear 406 and an output shaft 407. The first speed reduction gear 405 has a large end face meshing with the power shaft 401 and a small end face meshing with the second speed reduction gear 406. The power shaft 401 is driven by the rotating mechanism 2, and the power shaft 401 cooperates with the large end face of the first speed reduction gear 405 to achieve speed reduction; the small end face of the first speed reduction gear 405 cooperates with the second speed reduction gear 406 to achieve speed reduction again; the second speed reduction gear 406 is connected to the output shaft 407, so that after step-by-step speed reduction, the power of the water flow can be transmitted to the power distribution mechanism 6 located in the fourth chamber 1D through the output shaft 407. It can be understood that the number of speed reduction gears arranged between the power shaft 401 and the output shaft 407 can be set according to demand to meet the demand of the speed reduction ratio.

[0118] For example, the aforementioned speed reduction mechanism 4, power distribution mechanism 6 and distribution mechanism may be located in separate chambers. Figure 8 As shown, the first distribution mechanism 3A and the second distribution mechanism 3B are both arranged in the second chamber 1C. Here, the housing 1 may also include a second end cover 103, and the end cover 103 cooperates with the housing 101 to form the second chamber 1C. The housing 101 forms a third chamber 1B for accommodating the speed reduction mechanism 4 and a fourth chamber 1D for accommodating the power distribution mechanism 6, and the third chamber 1B and the fourth chamber 1D are located between the first chamber 1A and the second chamber 1C.

[0119] It can be understood that at least two of the aforementioned speed reduction mechanism 4, power distribution mechanism 6 and distribution mechanism are located in the same chamber. In some embodiments, the power distribution mechanism 6 can be arranged in the third chamber 1B, that is, the fourth chamber 1D is omitted. The third chamber 1B is located between the first chamber 1A and the second chamber 1C, so that the structure is compact, and the speed reduction mechanism 4 and the power distribution mechanism 6 are both located in the third chamber 1B, so that the treatment agent delivery device has a beautiful appearance. In some embodiments, the third chamber 1B and the fourth chamber 1D can be omitted, so that the speed reduction mechanism 4 and the power distribution mechanism 6 are both arranged in the second chamber 1C.

[0120] like Fig.11As shown, the power distribution mechanism 6 includes: a driving wheel 601, a first ratchet shaft 602, a driven wheel 603 and a second ratchet shaft 604; wherein the driving wheel 601 is connected to the output end of the speed reduction mechanism 4 (such as Fig.10 The output shaft 407 shown in the figure, the inner wall surface of the driving wheel 601 is provided with a first ratchet 6011; the first ratchet shaft 602 is sleeved in the driving wheel 601 and can cooperate with the first ratchet 6011 to rotate in one direction; the driven wheel 603 is meshed and connected with the driving wheel 601, and the inner wall surface of the driven wheel 603 is provided with a second ratchet 6031; the second ratchet shaft 604 is sleeved in the driven wheel 603 and can cooperate with the second ratchet 6031 to rotate in one direction. The first ratchet shaft 602 forms the first output end of the power distribution mechanism 6, and the second ratchet shaft 604 forms the second output end of the power distribution mechanism 6. It should be noted that the driving wheel 601 and the driven wheel 603 are meshed with external teeth, and the rotation directions of the two are opposite, and the first ratchet shaft 602 and the second ratchet shaft 604 have the same direction of unidirectional rotation. For example, taking the example of the first ratchet shaft 602 and the second ratchet shaft 604 both rotating unidirectionally clockwise, when the driving wheel 601 rotates clockwise, the first ratchet shaft 602 rotates clockwise under the drive of the first ratchet tooth 6011, the driven wheel 603 rotates counterclockwise, and the second ratchet shaft 604 and the second ratchet tooth 6031 slip and cooperate; when the driving wheel rotates counterclockwise, the first ratchet shaft 602 and the first ratchet tooth 6011 slip and cooperate, the driven wheel 603 rotates clockwise, and the second ratchet shaft 604 rotates clockwise under the drive of the second ratchet tooth 6031.

[0121] It can be understood that the driving wheel 601 is connected to the output end of the speed reduction mechanism 4, that is, connected to Fig.10 The output shaft 407 shown is rotated under the action of the power transmitted by the reduction mechanism 4. The driving wheel 601 and the first ratchet shaft 602 constitute a first ratchet assembly, and the driven wheel 603 and the second ratchet shaft 604 constitute a second ratchet assembly. Specifically, the outer wall surface of the first ratchet shaft 602 is provided with an elastic pawl that cooperates with the first ratchet tooth 6011, and the cooperation between the pawl and the first ratchet tooth 6011 makes the first ratchet shaft 602 only rotate in one direction; similarly, the outer wall surface of the second ratchet shaft 604 is provided with an elastic pawl that cooperates with the second ratchet tooth 6031, and the cooperation between the pawl and the second ratchet tooth 6031 makes the second ratchet shaft 604 only rotate in one direction. Since the driving wheel 601 is meshedly connected with the driven wheel 603, for example, meshedly connected by teeth or pins, the rotation directions of the driving wheel 601 and the driven wheel 603 are opposite. Fig.11As shown, the ratchet shaft and ratchet teeth slip in the counterclockwise direction and rotate in the clockwise direction as an example for explanation. When the driving wheel 601 rotates clockwise under the drive of the speed reduction mechanism 4, the driven wheel 603 rotates counterclockwise. At this time, the first ratchet shaft 602 is pushed by the first ratchet teeth 6011 of the driving wheel 601 and also rotates clockwise, but the second ratchet shaft 604 is in a slipping state because the driven wheel 603 rotates counterclockwise, and does not transmit torque. When the driving wheel 601 rotates counterclockwise under the drive of the speed reduction mechanism 4, the driven wheel 603 rotates clockwise. At this time, the first ratchet shaft 602 is in a slipping state and does not transmit torque, but the second ratchet shaft 604 rotates clockwise because the driven wheel 603 rotates clockwise, and the second ratchet shaft 604 rotates clockwise under the drive of the second ratchet teeth 6031 of the driven wheel 603, and outputs torque. In this way, when the output shaft 407 rotates clockwise, power is distributed to the first ratchet shaft 602 , and when the output shaft 407 rotates counterclockwise, power is distributed to the second ratchet shaft 604 .

[0122] In some embodiments, Fig.12 As shown, the second chamber 1C has two mutually isolated first guide channels 1017 and second guide channels 1018. For example, two mutually isolated first guide channels 1017 and second guide channels 1018 can be formed by injection molding in the second chamber 1C. The first guide channel 1017 has a first liquid inlet 1013A and a first liquid outlet 1014A, and the second guide channel 1018 has a second liquid inlet 1013B and a second liquid outlet 1014B. Here, the first liquid inlet 1013A and the second liquid inlet 1013B can share a control valve 5, that is, the first liquid inlet 1013A and the second liquid inlet 1013B are both connected to the output port 503 of the same control valve 5. In other embodiments, the first liquid inlet 1013A and the second liquid inlet 1013B can be connected to a control valve 5 respectively, that is, the first liquid inlet 1013A and the second liquid inlet 1013B are respectively connected to the output ports 503 of different control valves 5, and the input ports of different control valves 503 can share the water supply port 1016 or are connected to the water outlet 1012, which is not limited in the present application.

[0123] For example, the first dispensing mechanism 3A is a pump body disposed in the first flow guide channel 1017. It is understood that the first dispensing mechanism 3A can be an independent pump body or a pump body formed in cooperation with the inner wall surface of the first flow guide channel 1017. For example, the second dispensing mechanism 3B is a pump body disposed in the second flow guide channel 1018. It is understood that the second dispensing mechanism 3B can be an independent pump body or a pump body formed in cooperation with the inner wall surface of the second flow guide channel 1018.

[0124] Here, the first dispensing mechanism 3A and the second dispensing mechanism 3B may be a plunger pump, a vane pump, a diaphragm pump, a gear pump, etc., and this application does not make any specific limitation on this.

[0125] In some embodiments, Fig.12 As shown, the first ratchet shaft 602 drives the first dispensing mechanism 3A, and the second ratchet shaft 604 drives the second dispensing mechanism 3B. The first dispensing mechanism 3A includes a first gear 309 and a second gear 310 disposed in the first guide channel 1017. The first gear 309, the second gear 310 cooperate with the inner wall of the first guide channel 1017 to form a gear pump. When the first ratchet shaft 602 drives the first gear 309 to rotate, for example, Fig.12 As shown, when the first ratchet shaft 602 rotates counterclockwise, the first gear 309 rotates counterclockwise, and the second gear 310 meshing with the first gear 309 rotates clockwise. Under the cooperation of the first gear 309 and the second gear 310, the treatment agent or water enters through the first liquid inlet 1013A, fills the tooth gap, and then is squeezed out through meshing, flows out from the first liquid outlet 1014A, and is distributed to the corresponding pipeline or container; the second distribution mechanism 3B includes a third gear 311 and a fourth gear 312 arranged in the second guide channel 1018. The third gear 311 and the fourth gear 312 cooperate with the inner wall of the second guide channel 1018 to form a gear pump. When the second ratchet shaft 604 drives the third gear 311 to rotate, for example, Fig.12 As shown, when the second ratchet shaft 604 rotates counterclockwise, the third gear 311 rotates counterclockwise, and the fourth gear 312 meshing with the third gear 311 rotates clockwise. With the cooperation of the third gear 311 and the fourth gear 312, the treatment agent or water enters through the second liquid inlet 1013B, fills the tooth gap, and is then squeezed out through meshing, flows out from the second liquid outlet 1014B, and is distributed to the corresponding pipeline or container.

[0126] The present application also provides a washing device, comprising the treatment agent delivery device of the above embodiment. Based on the above treatment agent delivery device, the washing device can utilize the water flow of the waterway to achieve automatic delivery of the treatment agent.

[0127] In the embodiment of the present application, the washing device may be a washing machine or a dishwasher. Taking a washing machine as an example, the washing machine includes: a housing, a washing tub, and a water supply pipeline. The housing is also provided with a storage chamber for storing the treatment agent. The water inlet 1011 of the treatment agent delivery device is connected to the water inlet pipeline. The first input port 501 of the control valve 5 is connected to the water supply waterway, and the second input port 502 is connected to the storage chamber for storing the treatment agent. The water outlet 1012 and the liquid outlet 1014 can both be connected to the washing tub. In this way, the water flow of the water inlet 1011 can be used as a power source to realize the automatic delivery of the treatment agent in the storage chamber or the water introduced by the first input port 501 can be used to clean the delivery channel.
