[0002] In the related art, washing equipment often needs to add treatment agents during the washing process.

[0066] 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.

[0067] 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.

[0068] 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.

[0069] 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.

[0070] 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.

[0071] 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.

[0072] 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 9 As shown, the treatment agent delivery device comprises: a first chamber 1A, a rotating mechanism 2 and a delivery mechanism. The first chamber 1A has a water inlet 1011, and the rotating mechanism 2 is arranged in the first chamber 1A. The delivery mechanism is connected to the rotating mechanism 2 and is used to deliver the treatment agent under the drive of the rotating mechanism 2. Among them, the water inlet 1011 is located above the rotating mechanism 2, and the rotating mechanism 2 is used to rotate under the action of the kinetic energy and potential energy of the water flow to control the delivery mechanism to deliver the treatment agent.

[0073] It can be understood that the pressure of the water flow will exert a certain force on the rotating mechanism 2 and drive the rotating mechanism 2 to rotate, which is equivalent to the kinetic energy of the water flow driving the rotating mechanism 2 to rotate. In addition, since the height of the water inlet 1011 is higher than the rotating mechanism 2, the water flow entering from the water inlet 1011 will form a certain potential energy in the process of falling to the rotating mechanism 2 through the set height difference, and will also exert a certain force on the rotating mechanism 2, thereby further driving the rotating mechanism 2 to rotate. Here, the rotating mechanism 2 can be understood as a mechanism that converts the kinetic energy and potential energy of the water flow into mechanical energy. Since the rotating mechanism 2 fully utilizes the kinetic energy and potential energy of the water flow as a power source, it can effectively improve the effect of water flow driving under low water pressure conditions, thereby broadening the working range of the water pressure and improving the working reliability of the treatment agent delivery device.

[0074] For example, Figure 2 As shown, the rotating mechanism 2 may include: a rotating body 21 and a plurality of first blades 22 arranged along the circumference of the rotating body 21. It is understandable that the water flow entering from the water inlet 1011 may act on the first blades 22 to generate a driving force to drive the rotating body 21 to rotate.

[0075] Exemplarily, the first blade 211 can be a curved blade or a straight blade, wherein a straight blade refers to a blade whose surface is planar, so that a force is applied to the rotating body 21 under the drive of the water flow to drive the rotating body 21 to rotate; a curved blade refers to a blade whose surface is curved, so that the blade has a set curvature, which is conducive to forming a rotating vortex to drive the rotating body 21 to rotate. The vortex is conducive to improving the rotation efficiency, and then to improving the energy conversion efficiency of the rotating mechanism 2.

[0076] Here, the rotating body 21 can be connected to the input end of the delivery mechanism. For example, a shaft connection hole structure can be provided at the end of the rotating body 21, and the power input shaft of the delivery mechanism can be fixed in the shaft connection hole structure, so that the rotating body 21 drives the delivery mechanism.

[0077] In some embodiments, Figure 1 As shown, the delivery mechanism includes: a speed reducing mechanism 4 and a distribution mechanism 3, wherein the input end of the speed reducing mechanism 4 is connected to the rotating mechanism 2; the distribution mechanism 3 is connected to the output end of the speed reducing mechanism 4; the power output by the rotating mechanism 2 is transmitted to the distribution mechanism 3 after being decelerated and torque increased by the speed reducing mechanism 4. Since the power output by the rotating mechanism 2 can be amplified after being decelerated and torque increased by the speed reducing mechanism 4, the torque output to the distribution mechanism 3 can be further increased while fully utilizing the kinetic energy and potential energy of the water flow, and the working range of the water pressure can be further widened.

[0078] Exemplarily, the speed reduction mechanism 4 includes a power shaft 401, such as Figure 1 As shown, the power shaft 401 extends into the first chamber 1A and is perpendicular to the upper end surface of the first chamber 1A, and the power shaft 401 is connected to the upper end surface of the rotating body 21. For example, the upper end surface of the rotating body 21 is provided with a rotating shaft connecting hole structure, and the power shaft 401 can be fixed in the rotating shaft connecting hole structure, so as to be driven by the rotating body 21.

[0079] In some embodiments, the rotating body 21 is a cone with a large upper end and a small lower end. Water flows into the first chamber 1A through the water inlet 1011. Under the blocking effect of the inner wall of the first chamber 1A, the water flow is guided to impact each first blade 22 along a direction approximately in the axial direction of the rotating body 21, thereby driving the rotating body 21 to rotate. Here, since the rotating body 21 is a cone with a large upper end and a small lower end, the water flow can be guided from the upper end of the rotating body 21 along the outer wall to the lower end, and in this process, the kinetic energy and potential energy are converted into impact force on the first blade 22, thereby improving the energy conversion efficiency of the rotating body 21 and facilitating the widening of the working range of the water pressure.

[0080] In some embodiments, the first chamber 1A also includes a water outlet 1012, which is located below the first blade 22. For example, the water outlet 1012 is located directly below the rotating body 21, so that the water flow entering the first chamber 1A from the water inlet 1011, under the blocking action of the inner wall of the first chamber 1A, hits each first blade 22 in a direction approximately axial to the rotating body 21, and is discharged through the water outlet 1012 directly below the rotating body 21.

[0081] In some embodiments, the rotating mechanism 2 further includes: an adjusting mechanism (not shown in the figure) for adjusting the installation angle of the first blade 22 on the rotating body 21, so that the rotation speed of the rotating body 21 under the action of the water flow is adjusted. Here, the adjusting mechanism can use a manual force mechanism or an electric mechanism to adjust the installation angle of the first blade 22 on the rotating body 21, and this application does not make specific limitations on this.

[0082] like Figure 3 As shown, the first blade 22 can adjust the installation angle within a certain range. Here, the installation angle can be understood as the angle θ formed by the length direction of the first blade 22 and the axial direction of the rotating body 21. By adjusting the installation angle of the first blade 22, the direction of the force of the rotating body 21 impacted by the water flow is changed, so as to achieve the purpose of controlling the rotation speed, thereby changing the delivery speed. For example, in the state of only water intake, the first blade 22 is rotated to the axial direction of the rotating body 21, that is, the installation angle θ is close to zero. At this time, the water flow falls through the rotating body 21. Since the length direction of the first blade 22 is close to the direction of the water flow, the force of the water flow on the first blade 22 is basically downward, that is, the direction of the force on the rotating body 21 is approximately vertical, and the force on the rotating body 21 along the circumferential direction is small, so that the delivery device only takes in water but does not dispense liquid. When it is necessary to add the treatment agent, the installation angle θ between the first blade 22 and the rotating body 21 is adjusted, and the first blade 22 is rotated to a suitable position. When the water flow falls, the contact area between the first blade 22 and the water flow is increased. In this way, by increasing the contact area between the first blade 22 and the water flow, the first blade 22 can generate a component force acting on the circumference of the rotating body 21 under the impact of the kinetic energy and potential energy of the water flow, so that the force on the rotating body 21 along the circumferential direction is increased, thereby increasing the rotation speed of the rotating body 21. In this way, the working range of the water pressure can be widened. For example, when the water pressure is low, by adjusting the installation angle of the first blade 22 to increase the force on the rotating body 21 along the circumferential direction, the output torque of the rotating body 21 can be increased.

[0083] In some embodiments, Figure 1 and Figure 4As shown, the first chamber 1A roughly forms a cylindrical chamber, the water inlet 1011 is located on the side wall of the first chamber 1A and is higher than the first blade 22, and the water outlet 1012 is located at the bottom of the first chamber 1A and directly faces the rotating body 21. Since the first chamber 1A is a cylindrical chamber, the rotating body 21 is a cone with a large upper end and a small lower end. Under the blocking effect of the inner wall of the cylindrical chamber, the water flow entering through the water inlet 1011 can impact the first blades 22 on the circumference of the rotating body 21 in a direction approximately in the axial direction of the rotating body 21, and then be discharged through the water outlet 1012 directly below the rotating body 21. Under the effect of the kinetic energy and potential energy of the water flow, each first blade 22 can exert a component force on the rotating body 21 along its circumference, thereby driving the rotating body 21 to rotate. For example, as Figure 4 As shown, the rotating body 21 rotates clockwise under the action of water flow.

[0084] In some embodiments, the delivery mechanism further includes: a second chamber 1C. The second chamber 1C has a liquid inlet 1013 and a liquid outlet 1014. The input end of the speed reduction mechanism 4 is connected to the rotating mechanism 2, and the output end of the speed reduction mechanism 4 is connected to the dispensing mechanism 3. The rotating mechanism 2 is driven to rotate by the water flow introduced by the water inlet 1011, and the power output by the rotating mechanism 2 is transmitted to the dispensing mechanism 3 after being decelerated and torque-increased by the speed reduction mechanism 4. The dispensing mechanism 3 drives the treatment agent to be introduced from the liquid inlet 1013 and discharged from the liquid outlet 1014. In this way, the treatment agent delivery device can use the water flow as a power source to realize the automatic delivery of the treatment agent, and the electric pump body can be omitted, thereby saving costs.

[0085] Here, the treatment agent may be a liquid or powdered washing product required for washing, and those skilled in the art may make a reasonable selection according to the needs, and this application does not make any specific limitation on this.

[0086] 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 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 water pressure, so that after the water flow in the low water pressure state 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, so that the dispensing mechanism 3 can drive the treatment agent to be introduced from the liquid inlet 1013 and discharged from the liquid outlet 1014, thereby realizing the automatic delivery of the treatment agent, which is beneficial to improving the reliability of the treatment agent delivery device.

[0087] For example, Figure 1 As shown, the treatment agent delivery device also includes: a housing 1, in which a first chamber 1A and a second chamber 1C are formed which are spaced apart from each other. The housing 1 includes a shell 101, a first end cover 102 and a second end cover 103, the first end cover 102 cooperates with the shell 101 to form the first chamber 1A, and the second end cover 103 cooperates with the shell 101 to form the second chamber 1C.

[0088] 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.

[0089] 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.

[0090] For example, Figure 1 and Figure 5 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.

[0091] In some embodiments, Figure 6As 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 input end of the power shaft 401 is connected to the rotating body 21, the power shaft 401 is connected to the first speed reduction gear 405, and the second speed reduction gear 406 has a first end face meshing with the first speed reduction gear 405 and a second end face for meshing with the output shaft 407. The first speed reduction gear 405 cooperates with the first end face of the second speed reduction gear 406 to achieve speed reduction; the second end face of the second speed reduction gear 406 cooperates with the output shaft 407 to achieve speed reduction again. In this way, 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.

[0092] 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.

[0093] In some embodiments, the dispensing mechanism 3 is located within the second chamber 1C.

[0094] In some embodiments, the dispensing mechanism 3 includes a pump body, 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. 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 power of the torque increase output by the speed reduction mechanism 4. For example, the input shaft of the pump body can be connected to Figure 1 The end 403A of the planet carrier 403 is shown or Figure 6 Output shaft 407 is shown.

[0095] For example, Figure 1 As shown, the second end cover 103 cooperates with the outer shell 101 to form a second chamber 1C, and the liquid inlet 1013 and the liquid outlet 1014 are respectively arranged on both sides of the outer shell 101. The treatment agent can enter the second chamber 1C through the liquid inlet 1013 and be discharged into the working chamber of the washing equipment through the liquid outlet 1014.

[0096] In some embodiments, Figure 7As 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 is connected to the output end of the reduction mechanism 4 (such as the end 403A of the planetary carrier 403 or the output shaft 407). 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 7 (as shown in the counterclockwise rotation), 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 7 As 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 treatment agent 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 in the sealing area is discharged through the liquid outlet 1014 under the action of pressure, thereby achieving the extraction and discharge of the treatment agent. Specifically, the second blade 302 and the elastic member 303 are arranged in a one-to-one correspondence with the groove 3011, so as to form a sealing area between adjacent second blades 302.

[0097] The specific process of dispensing the treatment agent by the dispensing mechanism 3 is as follows:

[0098] External water flows into the first chamber 1A through the water inlet 1011 and flows out from the water outlet 1012. The rotating body 21 rotates driven by the water flow. The rotational kinetic energy generated by the rotation of the rotating body 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 the treatment agent from small to large, and then discharges the treatment agent from large to small. The main body 301 rotates one circle to complete the absorption and discharge of the treatment agent.

[0099] In some embodiments, Figure 8 and Fig. 9 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 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 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 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.

[0100] 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.

[0101] 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.

[0102] 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 liquid inlet 1013 is connected to the storage chamber for storing the treatment agent, 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 the automatic delivery of the treatment agent in the storage chamber.

[0103] It should be noted that the technical solutions described in the embodiments of the present application can be combined arbitrarily without conflict.

[0104] 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.
