[0058] 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.

[0059] 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.

[0060] 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.

[0061] 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 device or element referred to 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.

[0062] 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.

[0063] 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.

[0064] The present application provides a detergent dispensing device, which can use water flow as a power source to achieve automatic detergent dispensing. Figures 1 to 5As shown, the detergent dispensing device comprises: a first chamber 1A, the first chamber 1A has a water inlet 1011 and a water outlet 1012; a second chamber 1C, the second chamber 1C has a liquid inlet 1013 and a liquid outlet 1014. A first rotating mechanism 2 is arranged in the first chamber 1A; a dispensing mechanism 3 is arranged in the second chamber 1C; a speed reduction mechanism 4, the input end of the speed reduction mechanism 4 is connected to the first rotating mechanism 2, and the output end of the speed reduction mechanism 4 is connected to the dispensing mechanism 3. The first rotating mechanism 2 rotates under the driving of the water flow introduced by the water inlet 1011, and the power output by the first rotating mechanism 2 is transmitted to the dispensing mechanism 3 after being decelerated and torque-increased by the speed reduction mechanism 4, and the dispensing mechanism 3 drives the detergent to be introduced from the liquid inlet 1013 and discharged from the liquid outlet 1014.

[0065] In this way, the detergent dispensing device can use water flow as a power source to achieve automatic detergent dispensing, and can save the electric pump body, thereby saving costs. Here, the detergent can be a liquid or powdered detergent product required for washing. Those skilled in the art can make a reasonable choice according to needs, and this application does not make specific restrictions on this.

[0066] In addition, 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 first 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 in the low-pressure water state drives the first rotating mechanism 2, the speed reduction mechanism 4 decelerates and increases the torque, thereby increasing the torque output by the dispensing mechanism 3, so that the dispensing mechanism 3 can drive the detergent to be introduced from the liquid inlet 1013 and discharged from the liquid outlet 1014, thereby realizing the automatic dispensing of detergent, which is beneficial to improving the reliability of the operation of the detergent dispensing device.

[0067] It is understandable that the first rotating mechanism 2 can be an impeller driven by water flow, such as a turbine or a propeller. As long as the first rotating mechanism 2 can rotate under the action of the water flow in the first chamber 1A to output power, this application does not make any specific restrictions on this.

[0068] In some embodiments, Figure 1 and Figure 2As shown, the first rotating mechanism 2 includes a first impeller 21, the rotating shaft of the first 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 first impeller 21, and the water flow enters through the water inlet 1011 to drive the first impeller 21 to rotate; the rotating shaft of the first impeller 21 is connected to the input end of the reduction mechanism 4. In this way, the first impeller 21 can rotate under the drive of the water flow, thereby converting the water energy into mechanical energy. Here, the first 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 end of the blade has a set curvature, which is conducive to the formation of a rotating vortex.

[0069] For example, Figure 1 and Figure 2 As shown, the detergent dispensing device comprises: a housing 1, in which a first chamber 1A and a second chamber 1C are formed and spaced from each other. The housing 1 comprises a shell 101 and a first end cover 102, wherein the first end cover 102 cooperates with the shell 101 to form the first chamber 1A, and a water inlet 1011 and a water outlet 1012 are respectively arranged on both sides of the shell 101. External water enters the first chamber 1A through the water inlet 1011, flows out through the water outlet 1012, and drives the first rotating mechanism 2 to rotate. For example, the direction of the water flow is along Figure 2 As shown by the arrow, the first rotating mechanism 2 located in the first chamber 1A rotates in the clockwise direction under the pressure of the water flow.

[0070] It can be understood 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 first rotating mechanism 2 driven by the water flow into a larger output torque, and this application does not make specific limitations on this.

[0071] 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.

[0072] For example, Figure 1 and Figure 3As 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 first rotating mechanism 2 and is driven by the first 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 formed 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 first 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.

[0073] In some embodiments, Figure 4 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 first 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 distribution mechanism 3 located in the second chamber 1C 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.

[0074] In some embodiments, the reduction ratio of the reduction mechanism 4 is 30 to 150: 1. Thus, the detergent dispensing device can work normally within the water pressure range of 0.03 MPa to 1.0 MPa, so that the detergent dispensing device has a wide range of application prospects, for example, it can be applied to household appliances such as washing machines or dishwashers.

[0075] In some embodiments, the dispensing mechanism 3 includes a pump body 30, the inlet of the pump body 30 is connected to the liquid inlet 1013, and the outlet of the pump body 30 is connected to the liquid outlet 1014. The pump body 30 can be at least one of a plunger pump, a vane pump, and a diaphragm pump. The pump body 30 can work under the torque-increased power output by the speed reduction mechanism 4. For example, the input shaft of the pump body 30 can be connected to Figure 3 The end 403A of the planet carrier 403 is shown or Figure 4 Output shaft 407 is shown.

[0076] For example, Figure 1 As shown, the shell 1 also includes a second end cover 103, which cooperates with the outer shell 101 to form a second chamber 1C. The liquid inlet 1013 and the liquid outlet 1014 are respectively arranged on both sides of the outer shell 101. The detergent can enter the second chamber 1C through the liquid inlet 1013 and be discharged into the working chamber of the washing device through the liquid outlet 1014.

[0077] In some embodiments, Figure 5 As shown, the dispensing mechanism 3 includes: a body 301, a second blade 302 and an elastic member 303; the 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 planet carrier 403 or the output shaft 407). Specifically, there is an eccentric distance between the center of the body 301 and the center of the second chamber 1C. The body 301 can rotate around the center of the body 301 in the second chamber 1C under the drive of the reduction mechanism 4, that is, eccentrically rotate relative to the second chamber 1C. A plurality of grooves 3011 arranged in the radial direction are provided on the body 301; the second blade 302 is installed in the groove 3011 through the elastic member 303. The body 301 rotates in the second chamber 1C driven by the speed reduction mechanism 4 (such as rotating counterclockwise as shown in FIG. 5 ). 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. In this way, a sealing area is formed between two adjacent second blades 302. Since the body 301 is eccentrically disposed in the second chamber 1C, a sealing area with a changing volume can be formed between the two second blades 302, the body 301 and the inner wall surface 1015. Figure 5As shown, when the body 301 rotates counterclockwise, 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 detergent 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 detergent in the sealing area is discharged through the liquid outlet 1014 under the action of pressure, thereby achieving the extraction and discharge of detergent. Specifically, the second blade 302 and the elastic member 303 are arranged one by one with the groove 3011, so as to form a sealing area between adjacent second blades 302.

[0078] The specific process of detergent dispensing by the dispensing mechanism 3 is as follows:

[0079] External water flows into the first chamber 1A through the water inlet 1011 and flows out from the water outlet 1012. The first impeller 21 rotates driven by the water flow. The rotational kinetic energy generated by the rotation of the first impeller 21 is transmitted to the reduction mechanism 4 through the power shaft 401, and the reduction mechanism 4 reduces speed and increases torque to drive the main body 301 to rotate. When the main body 301 rotates, the second blade 302 will cling to the inner wall surface 1015 of the outer 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 main body 301 and the inner wall surface 1015. The working volume absorbs detergent from small to large, and then discharges detergent from large to small. The main body 301 rotates one circle to complete the absorption and discharge of detergent.

[0080] 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 detergent 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 detergent 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 detergent 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.

[0081] 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. Those skilled in the art can make a reasonable design according to the needs to achieve automatic dispensing of detergent.

[0082] The embodiment of the present application further provides a washing device, comprising the detergent dispensing device of the above embodiment. Based on the above detergent dispensing device, the washing device can utilize the water flow of the water channel to achieve automatic detergent dispensing.

[0083] 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 cavity for storing detergent. The water inlet 1011 of the detergent delivery device is connected to the water inlet pipeline, the liquid inlet 1013 is connected to the storage cavity for storing detergent, and 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 automatic delivery of detergent in the storage cavity.

[0084] It should be noted that the technical solutions described in the embodiments of the present application can be combined arbitrarily without conflict.

[0085] 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.
