The embodiment of the application provides a treatment agent feeding device, and the treatment agent feeding device can utilize water flow as a power source to realize automatic feeding of the treatment agent. As shown in fig. 1 to 9, the treatment agent delivery device includes: the first chamber 1A, the rotating mechanism 2 and the throwing mechanism. The first chamber 1A has a water inlet 1011, and the rotating mechanism 2 is disposed in the first chamber 1A. The feeding mechanism is connected with the rotating mechanism 2 and is used for feeding the treating agent under the driving of the rotating mechanism 2. Wherein, the position above the water inlet 1011 rotating mechanism 2, the rotating mechanism 2 is used for rotating under the action of kinetic energy and potential energy of water flow to control the throwing mechanism to throw in the treating agent.

It can be understood that, the pressure of rivers can exert certain effort and drive slewing mechanism 2 and rotate to slewing mechanism 2, is equivalent to the kinetic energy drive slewing mechanism 2 of rivers and rotates, in addition, because the height of water inlet 1011 is higher than slewing mechanism 2, the rivers that get into from water inlet 1011 fall to slewing mechanism 2's in-process through setting for the altitude difference, can form certain potential energy, also can exert certain effort to slewing mechanism 2 to further drive slewing mechanism 2 and rotate. Here, the rotating mechanism 2 can be understood as a mechanism that converts kinetic energy and potential energy of water flow into mechanical energy, and since the rotating mechanism 2 makes full use of the kinetic energy and potential energy of water flow as a power source, the effect of water flow driving in a low water pressure state can be effectively improved, so that the working range of water pressure is widened, and the working reliability of the treating agent feeding device is improved.

Illustratively, as shown in fig. 2, the rotating mechanism 2 may include: a rotor 21 and a plurality of first blades 22 arranged along the circumferential direction of the rotor 21. It will be appreciated that the flow of water entering the water inlet 1011 may act on the first blade 22 to generate a driving force for driving the rotation of the rotor 21.

For example, the first blade 211 may be a curved blade or a straight blade, where the straight blade means that the surface of the blade is planar, so as to apply an acting force to the rotating body 21 under the driving of the water flow to drive the rotating body 21 to rotate; the curved surface blade means that the surface of blade is the curved surface form to make the blade have the radian of setting for, do benefit to and form rotatory vortex, rotate with drive rotor 21, the vortex does benefit to and improves the rotation efficiency, and then does benefit to and improves slewing mechanism 2's energy conversion efficiency.

Here, the rotor 21 can be connected to the input of the dispensing mechanism. For example, a rotating shaft connecting hole structure may be disposed at an end of the rotating body 21, and a power input shaft of the releasing mechanism may be fixed in the rotating shaft connecting hole structure, so that the rotating body 21 drives the releasing mechanism.

In some embodiments, as shown in fig. 1, the delivery mechanism comprises: the input end of the speed reducing mechanism 4 is connected with the rotating mechanism 2; the distribution mechanism 3 is connected with the output end of the speed reducing mechanism 4; the power output by the rotating mechanism 2 is transmitted to the distributing mechanism 3 after being decelerated and torque-increased by the decelerating mechanism 4. Because the power output by the rotating mechanism 2 can be amplified after being decelerated and torque-increased by the decelerating mechanism 4, the torque output to the distributing mechanism 3 can be further increased under the condition of fully utilizing the kinetic energy and the potential energy of the water flow, and the working range of the water pressure can be further widened.

Illustratively, the reduction mechanism 4 includes a power shaft 401, as shown in fig. 1, 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.

In some embodiments, the rotator 21 is a cone with a large upper end and a small lower end, and water enters the first chamber 1A through the water inlet 1011, and under the flow blocking effect of the inner wall of the first chamber 1A, the water is guided to impact each first blade 22 in a direction approximately along the axial direction of the rotator 21, so as to drive the rotator 21 to rotate. Here, since the rotator 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 rotator 21 to the lower end along the outer wall surface, and in the process, the kinetic energy and the potential energy are converted into the impact force on the first blades 22, thereby improving the energy conversion efficiency of the rotator 21 and facilitating the widening of the working range of the water pressure.

In some embodiments, the first chamber 1A further comprises a water outlet 1012, and the water outlet 1012 is located at a position 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 is discharged through the water outlet 1012 directly below the rotating body 21 after impacting each first blade 22 in a direction approximate to the axial direction of the rotating body 21 under the flow blocking effect of the inner wall of the first chamber 1A.

In some embodiments, the rotating mechanism 2 further comprises: and 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 rotating speed of the rotating body 21 under the action of the water flow is adjusted. Here, the adjusting mechanism may adjust the installation angle of the first blade 22 on the rotating body 21 by using a manual force applying mechanism or an electric mechanism, which is not particularly limited in the present application.

As shown in fig. 3, the first vane 22 can be adjusted in installation angle within a certain range, where the installation angle can be understood as an included angle θ formed between the length direction of the first vane 22 and the axial direction of the rotating body 21, and the direction of the force of the rotating body 21 impacted by the water flow is changed by adjusting the installation angle of the first vane 22, so as to achieve the purpose of controlling the rotating speed, thereby being capable of changing the throwing speed. For example, in the state of only water feeding, the first blade 22 is rotated to approximately the axial direction of the rotating body 21, that is, the installation angle θ is close to zero degree, at this time, the water flow falls through the rotating body 21, because the length direction of the first blade 22 is approximately the direction of the falling water flow, the acting force of the water flow on the first blade 22 is basically downward, that is, the direction of the force applied to the rotating body 21 is approximately vertical, the force applied to the rotating body 21 in the circumferential direction is small, and thus the dispensing device only feeds water and does not dispense liquid. When the treating agent needs to be added, the installation angle θ between the first blade 22 and the rotating body 21 is adjusted, the first blade 22 is rotated to a proper position, and after the water flow falls behind, the contact area between the first blade 22 and the water flow is increased, so that the first blade 22 can generate component force acting on the circumferential direction of the rotating body 21 under the impact of water flow energy and potential energy, the circumferential stress of the rotating body 21 is increased, the rotating speed of the rotating body 21 can be increased, and thus, the working range of water pressure can be widened, for example, when the water pressure is low, the installation angle of the first blade 22 is adjusted to increase the circumferential stress of the rotating body 21, and the output torque of the rotating body 21 can be increased.

In some embodiments, as shown in fig. 1 and 4, the first chamber 1A forms a substantially cylindrical chamber, the water inlet 1011 is located at a side wall of the first chamber 1A and above the first blade 22, and the water outlet 1012 is located at a bottom end of the first chamber 1A and faces the rotating body 21. Because 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, water entering from the water inlet 1011 can impact each first blade 22 on the circumferential direction of the rotating body 21 along the direction approximate to the axial direction of the rotating body 21 under the flow blocking effect of the inner wall of the cylindrical chamber, and then is discharged through the water outlet 1012 right below the rotating body 21, and each first blade 22 can exert component force on the rotating body 21 along the circumferential direction thereof under the action of the kinetic energy and the potential energy of the water, so that the rotating body 21 is driven to rotate. Illustratively, as shown in fig. 4, the rotor 21 is rotated clockwise by the water flow.

In some embodiments, the dispensing mechanism further comprises: a second chamber 1C. The second chamber 1C has a liquid inlet 1013 and a liquid outlet 1014. The input end of the speed reducing mechanism 4 is connected with the rotating mechanism 2, and the output end of the speed reducing mechanism 4 is connected with the distributing mechanism 3. The rotating mechanism 2 is driven to rotate by the water flow introduced from the water inlet 1011, the power output by the rotating mechanism 2 is transmitted to the distributing mechanism 3 after being decelerated and torque-increased by the decelerating mechanism 4, and the distributing mechanism 3 drives the treating agent to be introduced from the liquid inlet 1013 and discharged from the liquid outlet 1014. Therefore, the treating agent feeding device can utilize water flow as a power source, automatic feeding of the treating agent is achieved, an electric pump body can be omitted, and cost is saved.

Here, the treating agent may be a liquid or powder detergent product required for washing, and those skilled in the art can make a reasonable choice according to the needs, which is not specifically limited in the present application.

In addition, it should be noted that, because the water pressure of the water flow fluctuates during the use process, in the embodiment of the present application, the output power of the rotating mechanism 2 is transmitted to the distribution mechanism 3 after being decelerated and torque-increased by the decelerating mechanism 4, which can effectively widen the working range of the water pressure of the water flow, so that the deceleration and torque-increase by the decelerating mechanism 4 is performed after the water flow in the low water pressure state drives the rotating mechanism 2, thereby increasing the torque output by the distribution mechanism 3, and the distribution mechanism 3 can drive the treating agent to be introduced from the liquid inlet 1013 and to be discharged from the liquid outlet 1014, thereby realizing the automatic feeding of the treating agent, and being beneficial to improving the working reliability of the treating agent.

Illustratively, as shown in fig. 1, the treatment agent delivery device further includes: the device comprises a shell 1, wherein a first chamber 1A and a second chamber 1C are formed in the shell 1 and are arranged at intervals. The housing 1 includes a casing 101, a first end cap 102 and a second end cap 103, wherein the first end cap 102 cooperates with the casing 101 to form a first chamber 1A, and the second end cap 103 cooperates with the casing 101 to form a second chamber 1C.

It is understood that the reduction mechanism 4 may include, but is not limited to: the gear reducer, the worm gear reducer or the planetary reducer is not particularly limited in this application as long as the power output by the water flow-driven rotating mechanism 2 can be converted into a larger output torque.

It is understood that in other embodiments, the speed reducing mechanism 4 may be disposed in the second chamber 1C, so as to make the structure more compact.

Exemplarily, as shown in fig. 1 and 5, the reduction mechanism 4 includes: the power mechanism comprises a power shaft 401, a planetary gear 402, a planet carrier 403 and a gear ring 404, wherein the power shaft 401 is connected with a rotating mechanism 2 and is driven by the rotating mechanism 2; the ring gear 404 is fixed to the casing 101, and it is understood that the ring gear 404 may be a separately provided ring member having inner teeth on the inner wall thereof, the ring member being fixed to the inside of the third chamber 1B, or the ring gear 404 having an annular inner tooth surface is formed on the inner wall of the third chamber 1B; a planetary gear 402 is arranged between the power shaft 401 and the ring gear 404, and is in gear engagement with both the power shaft 401 and the ring gear 404; the carrier 403 is connected to the planetary gear 402, and outputs power to the distribution mechanism 3 by being driven by the planetary gear 402. It will be appreciated that a first end 401A of the power shaft 401 may extend into the first chamber 1A and be fixedly connected to the turning mechanism 2, and a second end 401B of the power shaft 401 is provided with external teeth meshing with the planetary gear 402, acting as a sun gear of the planetary reducer.

In this way, the power of the water flow can be transmitted to the distribution mechanism 3 located in the second chamber 1C via the output shaft 407 after the gradual deceleration. It will be appreciated that the number of reduction gears provided between the power shaft 401 and the output shaft 407 may be set as required to meet the requirement of a reduction ratio.

In some embodiments, the reduction ratio of the reduction mechanism 4 is 30-150: 1. Therefore, the treating agent feeding device can normally work within the water pressure range of 0.03MPa to 1.0MPa, so that the treating agent feeding device has wide application prospect, for example, the treating agent feeding device can be applied to household appliances such as washing machines or dish washing machines.

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

In some embodiments, the dosing mechanism 3 comprises a pump body, an inlet of which communicates with the inlet 1013 and an outlet of which communicates with the outlet 1014. The pump body can be at least one of a plunger pump, a vane pump and a diaphragm pump. The pump body may be operated by the torque-increased power output from the speed reduction mechanism 4, for example, the input shaft of the pump body may be connected to the end 403A of the planet carrier 403 shown in fig. 1 or the output shaft 407 shown in fig. 6.

Specifically, the center of the body 301 and the center of the second chamber 1C have an eccentricity therebetween, and the body 301 can rotate around the center of the body 301 within the second chamber 1C, i.e., eccentrically with respect to the second chamber 1C, under the drive of the reduction mechanism 4. A plurality of grooves 3011 arranged along the radial direction are arranged on the body 301; the second blade 302 is mounted in the recess 3011 via a resilient member 303. The body 301 is driven by the speed reducing mechanism 4 to rotate in the second chamber 1C (e.g., rotate counterclockwise as shown in fig. 7), under the action of the elastic member 303, the second blade 302 disposed in the groove 3011 extends outward along the groove 3011 to form a sealing fit with the inner wall surface 1015 of the second chamber 1C on the housing 101, so a sealing region is formed between two adjacent second blades 302, wherein, because the body 301 is eccentrically disposed in the second chamber 1C, a sealing region with a variable volume can be formed between the two second blades 302, the body 301 and the inner wall surface 1015.

Specifically, the second blades 302 and the elastic members 303 are disposed in one-to-one correspondence with the recesses 3011, so as to form sealing regions between the adjacent second blades 302.

The specific dosing process performed by the dosing mechanism 3 for dosing the treatment agent is as follows:
