[0015] The application has the following beneficial effects:

[0016] 1. The present invention uses a jacket to inject the heated liquid in the heating box into the jacket through the drain channel 1 and the liquid passage channel 2. Then the liquid flows out through the liquid passage channel 3 and the liquid passage channel 4. The jacket keeps the flame arrester warm and prevents it from freezing, which helps to prevent the medium from solidifying and crystallizing when passing through the flame arrester, thus preventing the flame arrester from becoming blocked. The liquid flowing out through the liquid passage channel 4 can be reintroduced into the heating box through the injection channel so that the liquid can be reused.

[0017] 2. The present invention, through the setting of the heating mechanism, uses the motor to drive the three mounting blocks to rotate in the heating chamber, causing the liquid in the heating chamber to rotate, so as to rapidly heat the liquid. This helps to prevent solid impurities from accumulating on the glass tube. Solid impurities are white lumps or powdery substances that gradually form from the minerals contained in the liquid after heating. The main components are calcium carbonate, magnesium hydroxide, magnesium carbonate, calcium sulfate, magnesium sulfate, calcium chloride, and magnesium chloride. This helps to prevent the accumulation of solid impurities in the heating chamber from adversely affecting the liquid heating output, so as to ensure timely supply of heating liquid to the jacket, so as to keep the flame arrester warm and prevent freezing, and prevent the flame arrester from clogging. The glass tube and the three mounting blocks are screwed and fixed, which makes it easy to remove the glass tube for repair.

[0018] 3. The present invention, through the setting of the waste discharge mechanism, removes solid impurities generated during liquid heating into the waste collection box. The waste collection box is equipped with a separator with small through holes to separate solid and liquid substances. When the heating chamber heats the liquid, the control gate is closed; when the heating chamber does not heat the liquid, the control gate is open. The waste discharge mechanism scrapes the solid impurities into the waste collection box, leaving the solid impurities on the separator. The liquid with the solid impurities removed is then pumped back into the heating chamber through the liquid passage, which is beneficial for the reuse of the liquid. The waste collection box is opened, and the separator is removed to remove the solid impurities on the separator.

[0019] 4. With the ventilation mechanism, when the heating chamber heats the liquid inside, the liquid in the heating chamber rises, the air in the heating chamber pushes the sealing block and the insert block upwards, the spiral beryllium copper wire contracts, the through groove on the receiving groove is exposed, and the air in the heating chamber flows out of the heating box through the channel, which is beneficial to protecting the structure inside the heating box.
