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 the amount and timing of addition are difficult to accurately grasp, 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-driven pump body needs to be set up, which increases the hardware cost and makes it difficult for washing machines with automatic addition functions to be widely promoted and applied. In addition, the amount of treatment agent added cannot be accurately controlled. Summary of the invention

[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 the present 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.

[0084] In the description of the present application, it should be understood that the terms "up", "down", "front", "back", "left", "right", "vertical", "horizontal", "top", "bottom", "inside", "outside", etc., indicating orientations or positional relationships, are based on the orientations or positional relationships shown in the accompanying drawings, and are only for the convenience of describing the present application and simplifying the description, and do not indicate or imply that the referred device or element must have a specific orientation, be constructed and operated in a specific orientation, and therefore should not be understood as a limitation on the present application.

[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. Moreover, a first feature being "above", "above" and "above" a second feature includes that the first feature is directly above and obliquely above the second feature, or simply indicates that the first feature is higher in level than the second feature. 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. Figures 1 to 6 As shown, the treatment agent delivery device comprises: a first chamber 1A, a rotating mechanism 2, a dispensing mechanism and a metering unit. The first chamber 1A has a first water inlet 1011 and a second water inlet 1012. The rotating mechanism 2 is arranged in the first chamber 1A, and is used to rotate under the drive of the water flow entering the first water inlet 1011 or the second water inlet 1012. The power output by the rotating mechanism 2 drives the dispensing mechanism to operate, and the dispensing mechanism comprises a first dispensing mechanism 5 and a second dispensing mechanism 6, and the first dispensing mechanism 5 and the second dispensing mechanism 6 are used to dispense the treatment agent respectively.

[0088] Since the rotating mechanism 2 can be driven by the water flow flowing into the first chamber 1A through the first water inlet 1011 or the second water inlet 1012, the power output by the rotating mechanism 2 drives the first dispensing mechanism and the second dispensing mechanism to respectively dispense the treatment agent, so that the treatment agent dispensing device can use the water flow as a power source to achieve automatic dispensing of the treatment agent, and the electric drive device can be omitted, thereby saving costs. 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 needs, and this application does not make specific restrictions on this.

[0089] In addition, the metering unit can measure the amount of the treatment agent dosed through the first dispensing mechanism 5 and the second dispensing mechanism 6, so that the treatment agent can be accurately dosed during the automatic treatment agent dosing process.

[0090] Here, the metering unit can detect the movement of the rotating mechanism 2 or the dispensing mechanism and meter the amount of the treatment agent to be added.

[0091] In some embodiments, the metering unit includes: an inductive switch 7 arranged at the rotating mechanism 2 or the dispensing mechanism, and the inductive switch 7 can detect the number of rotations of the corresponding mechanism or the number of reciprocating movements. For example, when the inductive switch 7 is arranged at the rotating mechanism 2, the inductive switch 7 can detect the number of rotations of the rotating mechanism 2. When the inductive switch 7 is arranged at the dispensing mechanism, the inductive switch 7 can detect the number of rotations of the first dispensing mechanism 5 and the second dispensing mechanism 6 or the number of reciprocating movements. Specifically, if the first dispensing mechanism 5 and the second dispensing mechanism 6 are actuators for circumferential motion, the inductive switch 7 detects the number of rotations of the actuators. If the first dispensing mechanism 5 and the second dispensing mechanism 6 are actuators for reciprocating motion, the inductive switch 7 detects the number of reciprocating movements of the actuators. For example, if the first dispensing mechanism 5 and the second dispensing mechanism 6 are both plunger pumps, the inductive switch 7 can detect the number of movements of each plunger pump to facilitate metering the amount of treatment agent.

[0092] It can be understood that the dispensing mechanism is used to dispense the treatment agent, and the induction switch 7 is arranged at the dispensing mechanism. By detecting the number of revolutions of the dispensing mechanism or the number of reciprocating motions, the number of times the treatment agent is dispensed can be directly reflected, thereby reasonably determining the amount of treatment agent dispensed based on the single set dispensing capacity and number of dispenses.

[0093] In some embodiments, the treatment agent delivery device further includes: a second chamber 1C, a speed reduction mechanism 3 and a power distribution mechanism 4. Here, the speed reduction mechanism 3 is connected to the rotating mechanism 2, and is used to reduce the power output by the rotating mechanism 2 and increase the torque before outputting it. The power distribution mechanism 4 is connected to the output end of the speed reduction mechanism 3, and the power distribution mechanism 4 has a first output end and a second output end for transmitting the power output by the speed reduction mechanism 3. The second chamber 1C has a first liquid inlet 1016 and a second liquid inlet 1018. The first distribution mechanism 5 is connected to the first output end, and is used to control the delivery of the treatment agent at the first liquid inlet 1016; the second distribution mechanism 6 is connected to the second output end, and is used to control the delivery of the treatment agent at the second liquid inlet 1018.

[0094] 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 power distribution mechanism 4 after being decelerated and torque-increased by the speed reduction mechanism 3, which can effectively widen the working range of the water flow pressure, so that after the water flow in the low water pressure state drives the rotating mechanism 2, the speed reduction mechanism 3 is decelerated and torque-increased, thereby increasing the torque output by the power distribution mechanism 4, so that the first distribution mechanism 5 or the second distribution mechanism 6 can effectively control the delivery of the treatment agent at its respective liquid inlet, thereby realizing the automatic delivery of the treatment agent, and since the first distribution mechanism 5 controls the delivery of the treatment agent at the first liquid inlet 1016 and the second distribution mechanism 6 controls the delivery of the treatment agent at the second liquid inlet, the classified automatic delivery of different types of treatment agents can be realized, thereby further saving the control cost of classified automatic delivery.

[0095] It can be understood that since the reduction mechanism 3 has a certain reduction ratio, by detecting the number of rotations of the reduction mechanism 3 or the number of rotations of the rotating mechanism 2 or the number of rotations of the power distribution mechanism 6, based on the corresponding reduction ratio and the detected number of rotations, the number of times the treatment agent is dosed can also be indirectly determined, thereby the amount of treatment agent dosed can be reasonably determined based on the single set dose capacity and number of doses.

[0096] Based on this, in some embodiments, the induction switch 7 can be set at any one of the rotating mechanism 2, the speed reduction mechanism 3, the power distribution mechanism 4 or the distribution mechanism. When the induction switch 7 is set at the speed reduction mechanism 3, the induction switch 7 can detect the number of rotations of the speed reduction mechanism 3. When the induction switch 7 is set at the power distribution mechanism 4, the induction switch 7 can detect the number of rotations of the power distribution mechanism 4 (for example, detecting the number of rotations of the first output end and / or the second output).

[0097] Preferably, the induction switch 7 is arranged at the dispensing mechanism, which can directly detect the number of times the treatment agent is dosed, avoiding the process of calculating the number of times the treatment agent is dosed based on the reduction ratio conversion, and the rotation speed of the rotating mechanism 2 is transmitted after being decelerated and torque-increased by the reduction mechanism. Compared with the speed mechanism 2, the frequency of rotation or reciprocating motion of the dispensing mechanism will be effectively reduced, which is more conducive to the detection of the induction switch and the accurate measurement of the amount of treatment agent dosed.

[0098] In some embodiments, the metering unit further includes: a controller (not shown in the figure), connected to the induction switch 7, and used to determine the amount of treatment agent to be delivered based on the output signal of the induction switch 7. Here, the controller can pre-configure the value of the delivery capacity of each dispensing mechanism for a single delivery, and determine the number of deliveries of each dispensing mechanism directly or through a conversion operation based on the output signal of the induction switch 7, and determine the delivery amount of detergent based on the delivery capacity and the delivery number, thereby achieving accurate measurement of the delivery of detergent. Here, the controller can be a separately arranged processor, or it can share a controller such as a computer control board of the washing equipment, which is not specifically limited in this application. Exemplarily, when the amount of detergent delivered reaches a set amount, the controller can control the water inlet valve at the first water inlet 1011 and / or the second water inlet 1012 to close and stop water inlet, so that the corresponding dispensing mechanism stops delivering detergent, thereby achieving automatic and accurate delivery of detergent.

[0099] Here, the induction switch 7 can be arranged in a one-to-one correspondence with the first dispensing mechanism 5 and the second dispensing mechanism 6, or the first dispensing mechanism 5 and the second dispensing mechanism 6 share a single induction switch 7. Figure 1 As shown, the induction switch 7 is arranged between the first dispensing mechanism 5 and the second dispensing mechanism 6. When the first dispensing mechanism 5 controls the first liquid inlet 1016 to dispense the treatment agent, the induction switch 7 can detect the number of actions of the first dispensing mechanism 5, and the controller can determine the amount of the treatment agent dispensed by the first dispensing mechanism 5 based on the number of actions of the first dispensing mechanism 5; when the second dispensing mechanism 6 controls the second liquid inlet 1018 to dispense the treatment agent, the induction switch 7 can detect the number of actions of the second dispensing mechanism 6, and the controller can determine the amount of the treatment agent dispensed by the second dispensing mechanism 6 based on the number of actions of the second dispensing mechanism 6. Since the number of actions of the first dispensing mechanism 5 or the second dispensing mechanism 6 can directly reflect the amount of the treatment agent dispensed, the controller can achieve accurate measurement of the treatment agent based on the number of actions of the first dispensing mechanism 5 or the second dispensing mechanism 6. For example, when the amount of treatment agent added by the first dispensing mechanism 5 reaches a set amount, the controller can control the first water inlet 1011 to stop water inflow, so that the first dispensing mechanism 5 stops adding treatment agent; or when the amount of treatment agent added by the second dispensing mechanism 6 reaches a set amount, the controller can control the second water inlet 1012 to stop water inflow, so that the second dispensing mechanism 6 stops adding treatment agent. Here, the controller can be a separately set processor, or can share a controller such as a computer control board of the washing equipment, which is not specifically limited in this application.

[0100] Here, the induction switch 7 can be at least one of a mechanical micro switch and a non-contact induction switch. Among them, the mechanical micro switch performs detection based on a contact method. The non-contact induction switch can perform detection based on a non-contact method, for example, it can be in the form of infrared induction, magnetic induction, ultrasonic wave, Hall switch, etc., which is not specifically limited in this application.

[0101] In an application example, the induction switch 7 is a mechanical micro switch. The mechanical micro switch is set at the dispensing mechanism for example. It is assumed that the mechanical micro switch is set between the first dispensing mechanism 5 and the second dispensing mechanism 6. The first dispensing mechanism 5 and the second dispensing mechanism 6 share the mechanical micro switch. The first dispensing mechanism 5 and the second dispensing mechanism 6 are respectively provided with a touch piece for touching the induction switch 7. During the rotation or reciprocating motion of the first dispensing mechanism 5 or the second dispensing mechanism 6, the touch piece will touch the mechanical micro switch, so that the mechanical micro switch outputs an electrical signal to the controller. Here, the controller can determine that the first dispensing mechanism 5 or the second dispensing mechanism 6 is in an action state based on the water inflow state, and count based on the electrical signal of the mechanical micro switch. In this way, the controller can measure the number of rotations or the number of reciprocating motions of the first dispensing mechanism 5 or the second dispensing mechanism 6. For the case where the mechanical micro switch is set at the rotating mechanism 2 or the speed reduction mechanism 3 or the power distribution mechanism 4, the above design can be referred to and will not be repeated here.

[0102] In an application example, the induction switch 7 is a Hall switch. The Hall switch is set at the dispensing mechanism for example. It is assumed that the Hall switch is set between the first dispensing mechanism 5 and the second dispensing mechanism 6, and the first dispensing mechanism 5 and the second dispensing mechanism 6 share the Hall switch. A follow-up magnet can be set on each of the first dispensing mechanism 5 and the second dispensing mechanism 6. When the magnet is opposite to the nearby Hall switch during the rotation or reciprocating motion of the first dispensing mechanism 5 or the second dispensing mechanism 6, the Hall switch outputs an electrical signal to the controller. The controller can determine that the first dispensing mechanism 5 or the second dispensing mechanism 6 is in an action state based on the water inflow state, and count based on the electrical signal of the Hall switch. In this way, the controller can measure the number of rotations or the number of reciprocating motions of the first dispensing mechanism 5 or the second dispensing mechanism 6. For the case where the Hall switch is set at the rotating mechanism 2, the speed reduction mechanism 3, or the power distribution mechanism 4, the above design can be referred to and will not be repeated here.

[0103] For example, Figure 1 and Figure 2As shown, the treatment agent delivery device comprises: a housing 1, in which a first chamber 1A and a second chamber 1C are formed and spaced from each other. A first water inlet 1011 and a second water inlet 1012 are located on a first side of the housing 1, and a water outlet 1013 is located on a second side of the housing 1. If water flows in from the first water inlet 1011 and flows out from the water outlet 1013, the rotating mechanism 2 is driven to rotate in a first direction; if water flows in from the second water inlet 1012 and flows out from the water outlet 1013, the rotating mechanism 2 is driven to rotate in a second direction.

[0104] Exemplarily, the first water inlet 1011 and the second water inlet 1012 are located on the first side of the housing 1 (i.e. Figure 2 The water outlet 1013 is located on the second side of the housing 1 opposite to the first side (i.e. Figure 2 if water flows in from the first water inlet 1011 and flows out from the water outlet 1013, the driving mechanism 2 is rotated in a first direction (eg Figure 2 If water flows in from the second water inlet 1012 and flows out from the water outlet 1013, the driving mechanism 2 rotates in the second direction (eg Figure 2 It can be understood that if water flows into the first water inlet 1011 and the second water inlet 1012 at the same time with similar flow rates, the power of the rotating mechanism 2 cancels each other out, that is, it can maintain a stationary state, but the water can flow out normally from the water outlet 1013. In this way, by controlling the water supply state of the first water inlet 1011 and the second water inlet 1012, the clockwise rotation, counterclockwise rotation and stationary state of the rotating mechanism 2 can be switched under the condition of normal water supply to the first chamber 1A. In actual applications, the first water inlet 1011 and the second water inlet 1012 can be connected to the water supply waterway via an electromagnetic valve, and the water supply state of the first water inlet 1011 and the second water inlet 1012 is controlled by the electromagnetic valve, so that the rotation state of the rotating mechanism 2 can be effectively controlled.

[0105] It is understandable that there can be multiple water outlets 1013 , and those skilled in the art can reasonably set them according to needs, which is not limited here.

[0106] It is understandable that those skilled in the art can reasonably set the position of the water outlet 1013 according to the needs, and no limitation is made here. For example, the side where the water outlet 1013 is located can be perpendicular to or opposite to the side where the first water inlet 1011 and the second water inlet 1012 are located.

[0107] In some embodiments, Figure 2As shown, the first chamber 1A is roughly 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. The first water inlet pipe 1020 and the second water inlet pipe 1021 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.

[0108] Exemplarily, a first water inlet 1011 is formed at the inlet of the first water inlet pipe 1020, a second water inlet 1012 is formed at the inlet of the second water inlet pipe 1021, and a water outlet 1013 is formed at the outlet of the water outlet pipe 1022; when water flows in from the first water inlet 1011, the rotating mechanism 2 is driven to rotate in the first direction; when water flows in from the second water inlet 1012, the rotating mechanism 2 is driven to rotate in the second direction.

[0109] It is understandable that the rotating mechanism 2 can be an impeller driven by water flow, such as a turbine or a propeller. As long as the rotating mechanism 2 can rotate and output power under the action of the water flow passing through the first chamber 1A, this application does not make any specific restrictions on this.

[0110] In some embodiments, Figure 1 and Figure 2 As shown, the rotating mechanism 2 includes an impeller 21, the rotating shaft of the impeller 21 is vertically arranged in the chamber 1A, the first water inlet 1011 and the second water inlet 1012 are located on one side of the impeller 21, and the water outlet 1013 is located on the other side of the impeller 21. After the water flows in through the first water inlet 1011 or the second water inlet 1012, it is suitable for driving the impeller 21 to rotate, and flows out through the water outlet 1013; the rotating shaft of the impeller 21 is connected to the input end of the reduction mechanism 3. 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 blades 211 fixed on the output shaft, and the blades 211 can be curved blades or straight blades, wherein the straight blade refers to the surface of the blade being planar, so as to rotate under the drive of the water flow; the curved blade refers to the surface of the blade being curved, so that the blade has a set curvature, which is conducive to the formation of a rotating vortex.

[0111] For example, Figure 1 and Figure 2 As shown, the housing 1 includes a shell 101 and a first end cover 102. The first end cover 102 cooperates with the shell 101 to form a first chamber 1A. The first water inlet 1011 and the second water inlet 1012 are spaced apart. Figure 2 On the left side of the housing 101 shown in FIG. 1 , for example, the first water inlet 1011 and the second water inlet 1012 are spaced apart from each other on the outer side of the housing 101; the water outlet 1013 is arranged at a position such as Figure 2The right side of the housing 101 is shown. For example, the direction of the water flow is along Figure 2 As shown by the arrow, the rotating mechanism 2 located in the first chamber 1A rotates in the clockwise direction or counterclockwise direction under the pressure of the water flow, or stops when the pressure is balanced and maintains normal water supply.

[0112] It can be understood that the reduction mechanism 3 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 any specific limitations on this.

[0113] For example, Figure 1 and Figure 3 As shown, the speed reduction mechanism 3 includes: a power shaft 301, a first speed reduction gear 302, a second speed reduction gear 303 and an output shaft 304. The first speed reduction gear 302 has a large end face meshing with the power shaft 301 and a small end face for meshing with the second speed reduction gear 303. The power shaft 301 can extend into the first chamber 1A and connect to the rotating mechanism 2, and is driven by the rotating mechanism 2. The power shaft 301 cooperates with the large end face of the first speed reduction gear 302 to achieve speed reduction; the small end face of the first speed reduction gear 302 cooperates with the second speed reduction gear 303 to achieve speed reduction again; the second speed reduction gear 303 is connected to the output shaft 304, so that the power of the water flow can be transmitted to the power distribution mechanism 4 through the output shaft 304 after step-by-step speed reduction. It can be understood that the number of speed reduction gears arranged between the power shaft 301 and the output shaft 304 can be set according to needs to meet the needs of the speed reduction ratio.

[0114] In some embodiments, Figure 4 As shown, the reduction mechanism 3 includes: a power shaft 301, a planetary gear 305, a planetary carrier 306 and a ring gear 307, wherein the power shaft 301 is connected to the rotating mechanism 2 and driven by the rotating mechanism 2; the ring gear 307 is fixed on the housing 101, and it can be understood that the ring gear 307 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 307 with an annular inner tooth surface is formed on the inner wall of the third chamber 1B; the planetary gear 305 is arranged between the power shaft 301 and the ring gear 307, and is meshed with the power shaft 301 and the ring gear 307; the planetary carrier 306 is connected to the planetary gear 305, and outputs power to the power distribution mechanism 4 under the drive of the planetary gear 305. It can be understood that one end of the power shaft 301 can extend into the first chamber 1A and be fixedly connected to the rotating mechanism 2, and the other end of the power shaft 301 is provided with external teeth meshing with the planetary gear 305, serving as the sun gear of the planetary reducer. The planet carrier 306 has an end for outputting power, which is connected to the input end of the power distribution mechanism 4.

[0115] In some embodiments, the reduction ratio of the reduction mechanism 3 is 30 to 150: 1. In this way, 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.

[0116] For example, the aforementioned speed reduction mechanism 3, power distribution mechanism 4 and distribution mechanism may be located in separate chambers. Figure 1 As shown, the distribution mechanism is arranged in the second chamber 1C, and a third chamber 1B accommodating the reduction mechanism 3 and a fourth chamber 1D accommodating the power distribution mechanism 4 are formed in the outer shell 101. The third chamber 1B and the fourth chamber 1D are located between the first chamber 1A and the second chamber 1C.

[0117] It is understandable that at least two of the aforementioned speed reduction mechanism 3, power distribution mechanism 4 and distribution mechanism are located in the same chamber. In some embodiments, the power distribution mechanism 4 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 3 and the power distribution mechanism 4 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 3 and the power distribution mechanism 4 are both arranged in the second chamber 1C.

[0118] like Figure 5 As shown, the power distribution mechanism 4 includes: a driving wheel 401, a first ratchet shaft 402, a driven wheel 403 and a second ratchet shaft 404; wherein the driving wheel 401 is connected to the output end of the speed reduction mechanism 3 (such as Figure 3 The output shaft 304 shown or Figure 4The planet carrier 306 shown in the figure, the inner wall surface of the driving wheel 401 is provided with a first ratchet 4011; the first ratchet shaft 402 is sleeved in the driving wheel 401, and can cooperate with the first ratchet 4011 to rotate in one direction; the driven wheel 403 is meshed and connected with the driving wheel 401, and the inner wall surface of the driven wheel 403 is provided with a second ratchet 4031; the second ratchet shaft 404 is sleeved in the driven wheel 403, and can cooperate with the second ratchet 4031 to rotate in one direction. The first ratchet shaft 402 forms the first output end of the power distribution mechanism 4, and the second ratchet shaft 404 forms the second output end of the power distribution mechanism 4. It should be noted that the driving wheel 401 and the driven wheel 403 are meshed with external teeth, and the rotation directions of the two are opposite, and the first ratchet shaft 402 and the second ratchet shaft 404 have the same direction of unidirectional rotation. For example, taking the example that both the first ratchet shaft 402 and the second ratchet shaft 404 rotate unidirectionally clockwise, when the driving wheel 401 rotates clockwise, the first ratchet shaft 402 rotates clockwise under the drive of the first ratchet tooth 4011, the driven wheel 403 rotates counterclockwise, and the second ratchet shaft 404 and the second ratchet tooth 4031 slip and cooperate; when the driving wheel rotates counterclockwise, the first ratchet shaft 402 and the first ratchet tooth 4011 slip and cooperate, the driven wheel 403 rotates clockwise, and the second ratchet shaft 404 rotates clockwise under the drive of the second ratchet tooth 4031.

[0119] It can be understood that the driving wheel 401 is connected to the output end of the speed reduction mechanism 3, that is, connected to Figure 3 The output shaft 304 shown or Figure 4 The end of the planet carrier 306 shown in the figure is so as to rotate under the action of the power transmitted by the reduction mechanism 3. The driving wheel 401 and the first ratchet shaft 402 constitute a first ratchet assembly, and the driven wheel 403 and the second ratchet shaft 404 constitute a second ratchet assembly. Specifically, the outer wall surface of the first ratchet shaft 402 is provided with an elastic pawl cooperating with the first ratchet tooth 4011, and the cooperation between the pawl and the first ratchet tooth 4011 makes the first ratchet shaft 402 only rotate in one direction; similarly, the outer wall surface of the second ratchet shaft 404 is provided with an elastic pawl cooperating with the second ratchet tooth 4031, and the cooperation between the pawl and the second ratchet tooth 4031 makes the second ratchet shaft 404 only rotate in one direction. Since the driving wheel 401 is meshedly connected with the driven wheel 403, for example, meshedly connected by teeth or pins, the rotation directions of the driving wheel 401 and the driven wheel 403 are opposite. Figure 5As shown, the ratchet shaft and the ratchet teeth slip in the counterclockwise direction and rotate in the clockwise direction as an example for explanation. When the driving wheel 401 rotates clockwise under the drive of the speed reduction mechanism 3, the driven wheel 403 rotates counterclockwise. At this time, the first ratchet shaft 402 is pushed by the first ratchet teeth 4011 of the driving wheel 401 and also rotates clockwise, but the second ratchet shaft 404 is in a slipping state because the driven wheel 403 rotates counterclockwise, and does not transmit torque. When the driving wheel 401 rotates counterclockwise under the drive of the speed reduction mechanism 3, the driven wheel 403 rotates clockwise. At this time, the first ratchet shaft 402 is in a slipping state and does not transmit torque, but the second ratchet shaft 404 rotates clockwise because the driven wheel 403 rotates clockwise. Under the push of the second ratchet teeth 4031 of the driven wheel 403, the second ratchet shaft 4042 rotates clockwise to output torque. In this way, when the output shaft 304 rotates clockwise, power is distributed to the first ratchet shaft 402 , and when the output shaft 304 rotates counterclockwise, power is distributed to the second ratchet shaft 404 .

[0120] For example, Figure 1 As shown, the housing 1 further comprises a second end cover 103 , which cooperates with the housing 101 to form a second chamber 1C. The second chamber 1C has a first liquid inlet 1016 , a first liquid outlet 10117 , a second liquid inlet 1018 and a second liquid outlet 1019 .

[0121] In some embodiments, the first dispensing mechanism 5 and / or the second dispensing mechanism 6 may be a pump body, and the input shaft of the pump body may be driven by the first ratchet shaft 402 or the second ratchet shaft 404, thereby realizing automatic delivery of the treatment agent. Here, the pump body may be a plunger pump, a vane pump, a diaphragm pump, a gear pump, etc., and this application does not specifically limit this.

[0122] In some embodiments, Figure 6 As shown, the first dispensing mechanism 5 and / or the second dispensing mechanism 6 can also be a pump body that moves back and forth under the drive of an external force.

[0123] like Figure 6As shown, the first dispensing mechanism 5 includes: a first pump housing 503, a first one-way valve 504, a second one-way valve 505 and a first crank slider mechanism 507, wherein a first pump inner cavity 506 is formed in the first pump housing 503, the first pump inner cavity 506 is connected to the first liquid inlet 1016 via the first one-way valve 504, and the treatment agent can enter the first pump inner cavity 506 unidirectionally through the first liquid inlet 1016 and the first one-way valve 504; the first pump inner cavity 506 is connected to the first liquid outlet 1017 via the second one-way valve 505, and the treatment agent in the first pump inner cavity 506 can be discharged unidirectionally through the second one-way valve 505 and the first liquid outlet 1017. The first crank slider mechanism 507 can convert the circumferential motion into the linear reciprocating motion under the drive of the first ratchet shaft 402, so that the slider matched with the first pump inner cavity 506 moves back and forth along the inner wall surface of the first pump inner cavity 506, so as to drive the treatment agent to enter unidirectionally through the first liquid inlet 1016 and the first check valve 504, and to be discharged unidirectionally through the second check valve 505 and the first liquid outlet 1017. Among them, the first crank slider mechanism 507 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.

[0124] like Figure 6 As shown, the second dispensing mechanism 6 includes: a second pump housing 603, a third one-way valve 604, a fourth one-way valve 605 and a second crank slider mechanism 607, wherein a second pump inner cavity 606 is formed in the second pump housing 603, the second pump inner cavity 606 is connected to the second liquid inlet 1018 via the third one-way valve 604, and the treatment agent can enter the second pump inner cavity 606 unidirectionally through the second liquid inlet 1018 and the third one-way valve 604; the second pump inner cavity 606 is connected to the second liquid outlet 1019 via the fourth one-way valve 605, and the treatment agent in the second pump inner cavity 606 can be discharged unidirectionally through the fourth one-way valve 605 and the second liquid outlet 1019. The second crank slider mechanism 607 can convert the circumferential motion into the linear reciprocating motion under the drive of the second ratchet shaft 404, so that the slider matched with the second pump inner cavity 606 moves back and forth along the inner wall surface of the second pump inner cavity 606, so as to drive the treatment agent to enter unidirectionally through the second liquid inlet 1018 and the third one-way valve 604, and to be discharged unidirectionally through the fourth one-way valve 605 and the second liquid outlet 1019. Among them, the second crank slider mechanism 607 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.

[0125] Exemplarily, the induction switch 7 is disposed between the first crank slider mechanism 507 and the second crank slider mechanism 607. When the first crank slider mechanism 507 or the second crank slider mechanism 607 reciprocates, the induction switch 7 is triggered to turn on and off. That is, the first crank slider mechanism 507 and the second crank slider mechanism 607 share one induction switch 7.

[0126] The following is an introduction to the working process of the controller measuring the delivery amount of the first dispensing mechanism 5 and the second dispensing mechanism 6 based on the induction switch 7:

[0127] When the rotating mechanism 2 rotates along the first direction driven by the water flow, it is converted into clockwise rotation of the output shaft 304 after being decelerated and torque-increased by the speed reduction mechanism 3. At this time, the power output by the output shaft 304 is distributed to the first ratchet shaft 402, and the first crank slider mechanism 507 is driven by the first ratchet shaft 402 to reciprocate. The controller can count the number of actions of the first crank slider mechanism 507 based on the electrical signal output by the induction switch 7, and determine the delivery amount of the first dispensing mechanism 5 based on the corresponding single delivery amount.

[0128] When the rotating mechanism 2 rotates along the second direction driven by the water flow, it is converted into counterclockwise rotation of the output shaft 304 after being decelerated and torque-increased by the speed reduction mechanism 3. At this time, the power is distributed to the second ratchet shaft 404, and the second crank slider mechanism 607 is driven by the second ratchet shaft 404 to reciprocate. The controller can count the number of actions of the second crank slider mechanism 607 based on the electrical signal output by the sensing switch 7, and determine the delivery amount of the second dispensing mechanism 6 based on the corresponding single delivery amount.

[0129] It can be understood that when the first crank slider mechanism 507 reciprocates once, the first pump cavity 506 sucks in a set amount of treatment agent from the first liquid inlet 1016 and discharges it through the first liquid outlet 1017. When the controller counts the treatment agent delivered by the first dispensing mechanism 5 to meet the preset value based on the output signal of the induction switch 7, the first water inlet 1011 of the first dispensing mechanism 5 can be controlled to stop supplying water. When the second crank slider mechanism 607 reciprocates once, the second pump cavity 606 sucks in a set amount of treatment agent from the second liquid inlet 1018 and discharges it through the second liquid outlet 1019. When the controller counts the treatment agent delivered by the second dispensing mechanism 6 to meet the preset value based on the output signal of the induction switch 7, the second water inlet 1012 of the second dispensing mechanism 6 can be controlled to stop supplying water. In this way, the automatic delivery of treatment agent and the precise delivery of treatment agent can be achieved.

[0130] It is understandable that in other embodiments, the first dispensing mechanism 5 and the second dispensing mechanism 6 may also be provided with a separate induction switch 7, and the present application does not limit this.

[0131] From the above description, it can be known that during the operation of the treatment agent delivery device of the embodiment of the present application, when water flows into the first chamber 1A through the first water inlet 1011, the rotating mechanism 2 rotates clockwise; when water flows into the first chamber 1A through the second water inlet 1012, the rotating mechanism 2 rotates counterclockwise; when the first water inlet 1011 and the second water inlet 1012 are controlled to simultaneously inlet water at a similar flow rate, the forward and reverse power of the rotating mechanism 2 cancel each other out, and the rotation remains unchanged, but the water can flow out normally through the water outlet 1013. After the rotation of the rotating mechanism 2 is decelerated and torque-increased by the speed reduction mechanism 3, the increased power is transmitted to the power distribution mechanism 4; the power distribution mechanism 4 distributes the increased power, and one form of the distributed power is distributed to the first distribution mechanism 5 through the first output end, and the other form of the distributed power is distributed to the second distribution mechanism 6 through the second output end. The first dispensing mechanism 5 controls the delivery of the treatment agent at the first liquid inlet 1016, and the second dispensing mechanism 6 controls the delivery of the treatment agent at the second liquid inlet 1018, so that different types of treatment agents can be automatically delivered by classification, and a treatment agent delivery device is shared, so that the control cost can be further reduced. In addition, the metering unit can control the amount of the automatically delivered treatment agent, so as to achieve accurate delivery of the treatment agent.

[0132] In some embodiments, the first dispensing mechanism 5 and / or the second dispensing mechanism 6 can also be a bin-type dispenser, which is suitable not only for the automatic dispensing of liquid treatment agents, but also for the automatic dispensing of solid treatment agents such as washing powder and laundry beads.

[0133] The embodiment of the present application also provides a washing device, including the treatment agent delivery device of the embodiment of the present application. Based on the aforementioned treatment agent delivery device, the washing device can use the water flow of the waterway to achieve automatic delivery of the treatment agent. It is understandable that the washing device can achieve classified automatic delivery of different types of treatment agents based on the treatment agent delivery device.

[0134] 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 box, a washing tub, and a water supply pipeline. A storage cavity for storing a treatment agent is also provided on the box, and the storage cavity may include a first cavity for storing a first treatment agent and a second cavity for storing a second treatment agent. The first water inlet 1011 and the second water inlet 1012 of the treatment agent delivery device are connected to the water inlet pipeline via a solenoid valve, the first liquid inlet 1016 is connected to the first cavity, the second liquid inlet 1018 is connected to the second cavity, and the water outlet 1013 and the first liquid outlet 1017 and the second liquid outlet 1019 can all be connected to the washing tub. When different treatment agents need to be delivered, the solenoid valve can be controlled to conduct different water inlets so that different dispensing mechanisms work to extract and deliver the treatment agents; when normal water inlet is required, the solenoid valve can be controlled to conduct the first water inlet 1011 and the second water inlet 1012 at the same time. In this way, the automatic classification delivery of different types of treatment agents can be achieved.

[0135] It should be noted that the technical solutions described in the embodiments of the present application can be combined arbitrarily without conflict.

[0136] The above is only a specific implementation of the present application, but the protection scope of the present application is not limited thereto. Any person skilled in the art who is familiar with the present technical field can easily think of changes or substitutions within the technical scope disclosed in the present application, which should be included in the protection scope of the present application. Therefore, the protection scope of the present application should be based on the protection scope of the claims.
