In one embodiment, as shown in fig. 6, the present invention provides a liquid treatment apparatus 200, comprising: a box 202 for storing liquid, wherein the box 202 is connected with the valve body 100 of any one of the above embodiments through a liquid return pipe 104 and a liquid outlet pipe 104 to form a liquid loop; a pump 204 for driving the liquid in the liquid circuit to flow with the liquid in the tank 202; a second communication piece 206 for communicating with the first communication piece 106; a controller 208 is coupled to the pump 204 and the second communication member 206.

An embodiment of the present invention provides a liquid treatment apparatus 200 that includes a second communication member 206 by definition to communicate with a first communication member 106 using the second communication member 206 to effect control of a pump 204.

Specifically, in the case of the first communication part 106 being powered on to operate, the first communication part 106 can send out a first signal, and the second communication part 206 in the liquid treatment device 200 connected to the valve body 100 controls the pump 204 to stop operating and end water return when receiving the first signal; and under the condition that the first communication piece 106 stops running under the condition of power failure, the first communication piece 106 does not send the first signal any more, and at the moment, the liquid treatment device 200 connected with the valve body 100 controls the pump 204 to run to continue water return.

In the process, the running state of the pump 204 can be controlled by using the temperature value of the liquid at the position of the valve body 100, so that the situation that water is continuously returned when the temperature value of the liquid is equal to or exceeds a preset temperature value, and the water return frequency is too many is reduced; meanwhile, the situation that the water return times are insufficient due to the fact that water return is finished in advance when the temperature value of the liquid does not reach the preset temperature value can be reduced, the temperature value of the liquid discharged from the liquid treatment device 200 is guaranteed to be stabilized around the preset temperature value, and the use experience of a user is improved.

In the above embodiment, the method further includes: a water temperature sensor 210 disposed in the tank 202; and a heating element 212 connected to the controller 208 and the water temperature sensor 210.

In this embodiment, the water temperature sensor 210 and the heating element 212 are arranged so that the temperature of the liquid in the tank 202 can be adjusted by using the water temperature sensor 210 and the heating element 212 in cooperation to reach a temperature satisfying the user's demand.

In one embodiment, the heating element 212 may be a heating tube, wherein the number of the heating tubes may be one or more, and the specific number may be selected according to the actual use situation.

In any of the embodiments described above, pump 204 is disposed on return line 104 and/or effluent line 104.

In this embodiment, the setting position of the pump 204 is specifically given, wherein the setting position of the pump 204 may be on the liquid return pipeline 104, may also be on the liquid outlet pipeline 104, and may also be set at the same time, so as to meet the use requirements in different scenarios.

In one embodiment, the pump 204 is disposed in the tank 202 and connected to the return line 104; or with the fluid outlet line 104, in order to avoid exposure to the current environment, which could affect the aesthetics of the fluid treatment device 200.

In any of the above embodiments, the liquid treatment apparatus 200 includes: a water heater.

In one embodiment, the liquid treatment device 200 may also be one of a gas water heater and an air energy water heater.
