[0002] Traditional smart toilets use soup storage heating, specifically using a water tank for continuous heat preservation and heating, which can easily cause a waste of electricity when not in use. In addition, the water storage tank is large in size, which brings many restrictions to the appearance and structural design of the smart toilet. In order to improve the above phenomenon, a heating smart toilet has appeared on the market. The heating smart toilet uses a heating module to heat the water, but when the water pressure is unstable and the water flow rate is too large or too small, the heating water temperature will be unstable. As the market's requirements for heating modules are getting higher and higher, the original heating modules are difficult to meet the heating water temperature stability and reliability requirements caused by sudden changes in flow when the water pressure is unstable. For this reason, how to effectively stabilize the water pressure in the water channel and improve the stability of the heating water temperature, while increasing the reliability of the heating module, the research on a pressure-reducing heating module for smart bathrooms is imminent.

At the same time, the integrated design of the pressure reducing valve and the heating module reduces the assembly of components and improves the overall integration and product reliability.

[0009] Compared with the prior art, the utility model has the following beneficial effects:

[0010] 1) After adding the pressure reducing valve, the wide water pressure of the external input is controlled within a stable pressure range and the water pressure is reduced through the pressure reducing effect of the pressure reducing valve, so that the water pressure on subsequent components is greatly reduced, which increases the stability of the heating module. At the same time, the integrated design of the pressure reducing valve and the heating module reduces the assembly of components and improves the overall integration and product reliability.

[0011] 2) The control mode of the pressure reducing valve is direct-acting, and the diaphragm of the back-pressure structure is cancelled, so that the size of the valve cavity of the pressure reducing valve is no longer limited by the size of the diaphragm, so that the space of the valve cavity of the pressure reducing valve is released, and the volume of the pressure reducing valve is reduced from the design, thereby realizing the miniaturization of the pressure reducing valve.

[0012] 3) The threads on the inner wall of the instant heating shell and the elastic design inside the ceramic heating tube are conducive to mixed flow heating of the water flow. The water flow first passes through the mixed flow effect of the spring inside the ceramic heating tube, and then passes through the rotating mixed flow effect of the threads on the inner wall of the instant heating shell. The water temperature is heated more evenly, the heating speed is faster, and the temperature is more stable, thereby improving the heating effect.
