In the description of the present application, it is to be noted that, unless otherwise explicitly specified or limited, the terms "mounted," "connected," and "connected" are to be construed broadly, e.g., as meaning either a fixed connection, a removable connection, or an integral connection; they may be connected directly or indirectly through intervening media, or they may be interconnected between two elements. The specific meaning of the above terms in the present application can be understood in a specific case by those of ordinary skill in the art.

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 7, the treatment agent delivery device includes: a first chamber 1A, a rotation mechanism 2, a dosing mechanism 3 and a metering unit. Therein, the first chamber 1A has a water inlet 1011. The rotating mechanism 2 is arranged in the first chamber 1A and is driven by water flow entering from the water inlet to rotate. The input end of the speed reducing mechanism 4 is connected with the rotating mechanism 2, and the distribution mechanism 3 is connected with the output end of the speed reducing mechanism 4 and used for throwing in the treating agent. The rotating mechanism 2 is driven by the water flow introduced from the water inlet 1011 to rotate, and 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. The distribution mechanism 3 controls the feeding of the treating agent under the driving of the speed reducing mechanism 4. Therefore, water flow can be used as a power source, automatic feeding of the treating agent is realized, an electric driving device can be omitted, and cost is saved.

Here, the metering unit may measure the amount of the treatment agent to be dispensed by detecting the operation of the rotating mechanism 2, the dispensing mechanism 3, or the decelerating mechanism 4.

In some embodiments, the metering unit comprises: and the inductive switch 5 is arranged at the rotating mechanism 2, the speed reducing mechanism 4 or the dispensing mechanism 3, and the inductive switch 5 can detect the number of rotating circles or the number of reciprocating motions of the corresponding mechanism. For example, when the inductive switch 5 is disposed at the rotating mechanism 2, the inductive switch 5 can detect the number of rotation turns of the rotating mechanism 2. When the inductive switch 5 is disposed at the speed reducing mechanism 4, the inductive switch 5 can detect the number of rotation turns of the speed reducing mechanism 4. When the inductive switch 5 is disposed at the dispensing mechanism 3, the inductive switch 5 may detect the number of rotation turns or the number of reciprocating motions of the dispensing mechanism 3. Specifically, if the dispensing mechanism 3 is an actuator that moves in the circumferential direction, the inductive switch 5 detects the number of rotations of the actuator, and if the dispensing mechanism 3 is an actuator that moves in the reciprocating direction, the inductive switch 5 detects the number of times the actuator moves in the reciprocating direction, and for example, if the dispensing mechanism 3 is a plunger pump, the inductive switch 5 can detect the number of times the plunger pump moves so as to measure the amount of the treatment agent to be dispensed.

It can be understood that the dosing mechanism 3 is used for dosing the treating agent, the inductive switch 5 is arranged at the dosing mechanism 3, and the dosing frequency of the treating agent can be directly reflected by detecting the number of rotation turns or the reciprocating motion times of the dosing mechanism 3, so that the dosing amount of the treating agent can be reasonably determined based on the dosing capacity and the dosing frequency set at a single time.

It can be understood that, since the speed reducing mechanism 4 has the determined speed reducing ratio, the number of times of dosing the treatment agent can also be indirectly determined by detecting the number of rotations of the speed reducing mechanism 4 or the number of rotations of the rotating mechanism 2 based on the corresponding speed reducing ratio and the detected number of rotations, so that the dosing amount of the treatment agent can be reasonably determined based on the dosing capacity and the dosing number set at a single time.

Preferably, the inductive switch 5 is arranged at the dosing mechanism 3, the dosing frequency of the treating agent can be directly detected, the process of calculating the dosing frequency of the treating agent based on reduction ratio conversion is avoided, the rotating speed of the rotating mechanism 2 is reduced and increased in torque through the reducing mechanism and then is transmitted to the dosing mechanism 3, compared with the rotating speed mechanism 2, the rotating or reciprocating frequency of the dosing mechanism 3 is effectively reduced, the inductive switch detection is facilitated, and the accurate metering of the dosing amount of the treating agent is facilitated.

In some embodiments, the metering unit further comprises: and a controller (not shown in the figure) connected with the inductive switch 5 and used for determining the adding amount of the treating agent based on the output signal of the inductive switch 5. Here, the controller may pre-configure a numerical value of the dosing capacity of a single dosing of the dosing mechanism 3, determine the number of dosing times of the dosing mechanism 3 directly or through a conversion operation based on the output signal of the inductive switch 5, and determine the dosing amount of the treatment agent based on the dosing capacity and the number of dosing times, thereby achieving accurate metering of the dosing of the treatment agent. Here, the controller may be a processor separately provided, or may also be a controller such as a computer control board of the washing apparatus, and the present application is not limited thereto. For example, the controller may control the water inlet valve at the water inlet 1011 to close and stop water inlet when the amount of the treating agent reaches a set amount, so that the dosing mechanism 3 stops dosing the treating agent, thereby achieving automatic and accurate dosing of the treating agent.

Here, the inductive switch 5 may be at least one of a mechanical micro-motion switch and a non-contact inductive switch. Wherein the mechanical microswitch is detected on the basis of contact. The non-contact inductive switch may detect based on a non-contact manner, for example, the non-contact inductive switch may be in the form of infrared induction, magnetic induction, ultrasonic waves, a hall switch, and the like, which is not specifically limited in this application.

In an application example, the inductive switch 5 is a mechanical micro-switch, which is disposed at the dispensing mechanism 3 for illustration, a touch piece for touching the inductive switch 5 is disposed on the dispensing mechanism 3, and during the rotation or reciprocation of the dispensing mechanism 3, the touch piece may touch the mechanical micro-switch near the dispensing mechanism 3, so that the mechanical micro-switch outputs an electrical signal to the controller, and thus, the number of rotation turns or the number of reciprocation actions of the dispensing mechanism 3 can be measured by the controller. For the case where the mechanical microswitch is provided at the rotating mechanism 2 or the speed reducing mechanism 4, the above design can be referred to, and the details are not described herein.

In an application example, the inductive switch 5 is a hall switch, which is described by taking the example that the hall switch is disposed at the dispensing mechanism 3, a follow-up magnet may be disposed on the dispensing mechanism 3, and when the magnet is opposite to the nearby hall switch in the rotating or reciprocating process of the dispensing mechanism 3, the hall switch outputs an electrical signal to the controller, so that the controller can measure the number of rotation turns or the number of reciprocating motions of the dispensing mechanism 3. For the case where the hall switch is provided at the rotating mechanism 2 or the speed reducing mechanism 4, the above-described design can be referred to, and the description thereof is omitted.

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, so that the working range of the water pressure of the water flow can be effectively widened, and the deceleration and torque-increase by the decelerating mechanism 4 can increase the torque output by the distribution mechanism 3 after the water flow in a low water pressure state drives the rotating mechanism 2, so that the distribution mechanism 3 can effectively act, thereby realizing the automatic feeding of the treating agent, and being beneficial to improving the working reliability of the treating agent feeding device.

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. 4. It can be understood that the inductive switch 5 can detect the number of times of the pump body movement, so that the controller can determine whether the dosing amount of the treatment agent meets a preset value or not based on the counted number of times of the pump body movement, thereby realizing accurate dosing of the treatment agent.

Taking a plunger pump as an example, as shown in fig. 6 and 7, the dispensing mechanism 3 may comprise: a pump housing 304, a first check valve 305, a second check valve 306 and a slider-crank mechanism 308, wherein a pump cavity 307 is formed in the pump housing 304, the pump cavity 307 is communicated with the liquid inlet 1013 through the first check valve 305, and a treating agent or water can enter the pump cavity 307 in a one-way manner through the liquid inlet 1013 and the first check valve 305; the pump cavity 307 is communicated with the liquid outlet 1014 through the second check valve 306, and the treating agent or the water in the pump cavity 307 can be discharged in one way through the second check valve 306 and the liquid outlet 1014. The crank-slider mechanism 308 can convert the circumferential motion into a linear reciprocating motion under the driving of the output end of the speed reducing mechanism 4, so that the slider matched with the pump inner cavity 307 is displaced back and forth along the inner wall surface of the pump inner cavity 307, so as to drive the treating agent or water to enter in one way through the liquid inlet 1013 and the first check valve 305 and to be discharged in one way through the second check valve 306 and the liquid outlet 1014. Here, the inductive switch 5 may detect the number of times of the movement of the slider-crank mechanism 308, and thus, the controller may determine whether the amount of the treatment agent to be dispensed satisfies a preset value based on the counted number of times of the movement, thereby achieving accurate dispensing of the treatment agent. The crank-slider mechanism 308 is a planar linkage mechanism that uses a crank and a slider to realize mutual conversion between rotation and movement, and the specific structure is not described herein again.
