The first sealing ring 304 improves the sealing between the heater 302 and the heating box 301 to avoid leakage during use.

[0028] Specifically, a metal sleeve 306 is provided on the outside of the heating rod 303, and heat transfer oil 305 is filled between the metal sleeve 306 and the heating rod 303. The metal sleeve 306 is made of stainless steel. When the heating rod 303 is working, the heat transfer oil 305 transfers heat to the metal sleeve 306 to heat the liquid. The stainless steel metal sleeve 306 is easy to clean and can prevent impurities from adhering to the metal sleeve 306 to affect the heating effect and cause energy waste.

[0029] Specifically, the internal thread connection of the heater 302 is connected to a threaded block 307, the bottom of the threaded block 307 is connected to a zinc rod 308, and the size of the zinc rod 308 matches that of the heating box 301.

The filter screen 313 filters the insoluble impurities generated during the heating operation of the valve to avoid affecting subsequent use.

[0032] Working principle: First, the heating rod 303 heats the passing liquid. When the heating rod 303 works, the heat-conducting oil 305 transfers heat to the metal sleeve 306 to heat the liquid. The stainless steel metal sleeve 306 is easy to clean and can prevent impurities from adhering to the metal sleeve 306 and affecting the heating effect, causing energy waste. At the same time, the zinc rod 308 is a metal that is more easily corroded. When it comes into contact with the heating valve and is in the same electrolyte environment, the zinc rod 308 will corrode before the valve metal, thereby protecting the valve metal from corrosion. Then the filter 313 filters the insoluble impurities generated during the valve heating operation to avoid affecting subsequent use. The mounting plate 310 is installed on the filter box 309 through the buckle 311 to fix the filter 313. The buckle 311 can improve the convenience of installation, facilitate the removal of the filter 313 for cleaning, and improve maintenance efficiency.
