[0036] Please refer to Figure 1 , Figure 1 It is a cross-sectional view of a water circulation structure 100 according to an exemplary embodiment of the present application.

[0037] The present application provides a water circulation structure 100, which includes a water circuit component 10 and a water circulation component 20. The water circuit component 10 includes a water channel 11, one end of the water channel 11 is a water inlet end 110, and the other end is a water outlet end 112. The water channel 11 supplies water to flow from the water inlet end 110 to the water outlet end 112. The water circulation component 20 is used to drive the water in the water channel 11 to flow from the water inlet end 110 to the water outlet end 112 to form a circulation loop. The water circulation component 20 can enable water to circulate in the water channel 11. For example, water flowing from the water inlet end 110 to the water outlet end 112 will be sent to the water inlet end 110 again to realize the circulation of water from the water inlet end 110 to the water outlet end 112. In addition, the water circulation component 20 is configured to be able to transport water at at least two water delivery speeds.

[0038] The water circuit circulation structure 100 has a working state and a water circuit self-cleaning state. The water circuit component 20 delivers water at a first water delivery speed in the working state and delivers water at a second water delivery speed in the water circuit self-cleaning state, and the second water delivery speed is greater than the first water delivery speed. Taking the water circuit circulation structure of a foot bath as an example, the working state here refers to the cleaning state of the feet, and the water circuit self-cleaning state here refers to the cleaning state of the water circuit component of the foot bath after the foot cleaning is completed.

[0039] According to the above description, the water circulation component 20 can transport water at at least two water delivery speeds. Therefore, the higher water delivery speed of the water circulation component 20 can be used to increase the water flow rate in the water channel self-cleaning state, thereby increasing the momentum of the water to flush the inner wall of the water channel 11, so that the water channel 11 can achieve self-cleaning, reduce the dirty, mold and other harmful substances in the water channel 11, and improve the safety of the water channel component 10.

[0040] It should be noted that the water delivery speed of the water circulation component 20 can be set according to actual needs. For example, the water circulation component 20 can be set to work at a first water delivery speed when the water circulation structure 100 is in the working state, and the water circulation component 20 can be set to work at a second water delivery speed when the water circuit is in the self-cleaning state. In addition, the water delivery speed of the water circulation component 20 can be configured to be three or more.

[0041] In one embodiment, the water circulation component 20 includes a water inlet 21 and a water outlet 22, wherein the water inlet 21 is connected to the water outlet 112, and the water outlet 22 is connected to the water inlet 110. Two negative pressures corresponding to the working state and the waterway self-cleaning state can be formed at the water inlet 21. With this arrangement, different negative pressures at the water inlet 21 result in different water delivery speeds in the water channel 11.

[0042] The water pumping port 21 may form a first negative pressure and a second negative pressure, and the first negative pressure is different from the second negative pressure, thereby making the flow rate of water in the water channel 11 different. When the water circulation structure 100 is in the working state, the first negative pressure may be formed at the water pumping port 21, and under the first negative pressure, the water in the water channel 11 can be transported from the water inlet end 110 to the water outlet end 112 at a first water transfer speed. When the water circulation structure 100 is in the water self-cleaning state, the second negative pressure may be formed at the water pumping port 21, and under the second negative pressure, the water in the water channel 11 can be transported from the water inlet end 110 to the water outlet end 112 at a second water transfer speed.

[0043] In a specific embodiment, the water circulation component 20 includes a circulating water pump and a water pipeline. The circulating water pump can be configured with a variety of rotation speeds. Different rotation speeds result in different negative pressures at the water pumping port 21. In this solution, the negative pressure at the water pumping port is used to produce a suction effect on the water in the water channel 11, so that the water circulates and the kinetic energy is increased, thereby achieving self-cleaning, and the structure is simple and easy to implement.

[0044] In another embodiment, the water circulation component 20 may include a water delivery blade, which is rotatably disposed in the water channel 11, and the rotation direction of the water delivery blade is set to make the water in the water channel 11 flow from the water inlet end 110 to the water outlet end 112 when rotating, and can rotate at least two speeds. That is, the water delivery blade is provided with a first speed and a second speed, and the water delivery blade delivers water at the first speed in the working state, and delivers water at the second speed in the waterway self-cleaning state. In this scheme, the rotation of the water delivery blade can generate kinetic energy, and transfer it to the water in the water channel 11, so that the kinetic energy of the water is increased, the flow rate is increased, and the self-cleaning of the water channel 11 is achieved. For example, the water delivery blade can rotate under the drive of a motor. The water circulation component 20 may include a plurality of water delivery blades, and the plurality of water delivery blades may be spaced from the water inlet end 110 to the water outlet end 112, and the rotation speeds of the plurality of water delivery blades may be the same in the same state.

In actual application scenarios, dirt is mostly accumulated at the bottom of the water channel 11. If the water outlet is located at a higher position, even higher than the water inlet, the circulation of the water flow at the higher water level will be better, while the circulation of the water flow at the lower water level will be poor, so that in the process of water flowing from the water inlet end 110 to the water outlet end 112, dirt is easily accumulated at the bottom of the water channel 11. In the present application, setting the water outlet lower than the water inlet will improve the circulation of the water flow at the lower water level, thereby reducing or even avoiding the accumulation of dirt, and the self-cleaning effect is better.

[0046] In a specific embodiment, the water inlet may be disposed at the top of the water inlet end 110, such as the highest position of the water channel 11, thereby increasing the height difference between the water inlet and the water outlet and increasing the amount of circulating water.

At least one end of the heater 31 is a wiring terminal, which extends out of the water channel 11 and is used to supply power to the heater 31. In an optional embodiment, both ends of the heater 31 can be set as wiring terminals.

The sealing ring 50 is in contact with the end and is made of a heat-conducting material. The temperature sensor is used to sense the temperature of the sealing ring 50 and output a corresponding electrical signal, which is processed and used to control the start and stop of the heater 31. With this arrangement, the temperature of the heater 31 can be monitored to prevent damage caused by overheating of the heater 31. In addition, the heater 31 can also be controlled according to the heating temperature set.
