    The smart toilet also has a smart toilet cover with multiple flushing modes, which not only effectively removes dirt, but also has a massage effect. The front and rear movable nozzles can meet the different flushing needs of boys and girls. When using the smart toilet, due to The water flow will directly contact the user's skin during the cleaning process, so the water temperature needs to be constant, and the temperature needs to be within a safe range. Therefore, a built-in NTC temperature sensor is needed to control the water temperature of the smart toilet.

    The smart toilet water temperature heating device consists of a water inlet and outlet mechanism, an instant heating mechanism, a control mechanism and a power supply mechanism. The water outlet mechanism includes a first connecting pipe, an NTC temperature sensor, a water path switching component, a first water outlet component, and a second water outlet component. The water inlet end of the first connecting pipe is connected to the instant heating mechanism, and the water outlet end is connected to the water path switching component inlet end. connection, the NTC temperature sensor is installed at the water inlet and outlet to detect the water temperature. The outlet end of the water path switching component is connected to the first water outlet component and the second water outlet component respectively; the control mechanism includes an MCU and a PID controller, and the water inlet mechanism, instant heat The heating mechanism, power supply mechanism, water circuit switching component, PID controller and NTC temperature sensor are connected to the MCU and the PID controller. The PID controller is used to control the water temperature.
