[0026] Please see Figure 1 and Figure 4 A liquid inlet filtration mechanism 20 is provided on the left side of the main body 2. The liquid inlet filtration mechanism 20 includes a connecting plate 10, a liquid inlet pipe 11, a connecting frame 14, a screw 15, and abutting bolts 16. The outer surface of the connecting plate 10 is fixedly connected to the interior of the explosion-proof insulation shell 1, and the right side of the connecting plate 10 is fixedly connected to the left side of the main body 2. The outer surface of the liquid inlet pipe 11 is fixedly connected to the interior of the connecting plate 10. A rectangular groove 13 is provided on the left side of the connecting plate 10. The right side of the connecting frame 14 is slidably connected to the inner wall of the rectangular groove 13. The outer surface of the screw 15 is threadedly connected to the interior of the connecting frame 14. The interior of the abutting bolt 16 is threadedly connected to the outer surface of the screw 15. The back of the connector 10 abuts against the front of the connector 14. A connecting flange 12 is fixedly installed on the left side of the inlet pipe 11. A receiving plate 17 is fixedly installed on the left side of the connector 14, and the outer surface of the receiving plate 17 is snapped into the inside of the inlet pipe 11. A filter screen 18 is fixedly installed on the back of the receiving plate 17, and the outer surface of the filter screen 18 is snapped into the inside of the inlet pipe 11. Through the use of the connecting plate 10, the inlet pipe 11, the connector 14, the screw 15, the abutting bolt 16, the receiving plate 17, and the filter screen 18, a more convenient filtration effect can be achieved, and the filter screen 18 can be removed for cleaning, which improves the efficiency of actual use and reduces the burden during use.

[0027] Please see Figure 1 and Figure 2The explosion-proof insulation shell 1 has a heating base 3 fixedly installed inside, and the left side of the heating base 3 is fixedly connected to the right side of the main body 2. Two sets of support frames 4 are fixedly installed at the bottom of the explosion-proof insulation shell 1, and the upper surfaces of the two sets of support frames 4 are fixedly connected to the two sides of the bottom of the explosion-proof insulation shell 1. The use of support frames 4 can provide relevant support for the overall use, avoiding poor stability during actual use. The explosion-proof insulation shell 1 has a liquid outlet 21 fixedly installed inside, and the outer surface of the liquid outlet 21 is fixedly connected to the inside of the main body 2, which can drain the used liquid and avoid affecting the use.

[0028] Working principle: During use, when filtering the incoming liquid, the external liquid can first enter the interior of the main body 2 through the inlet pipe 11. As the liquid passes through the inlet pipe 11, the filter screen 18 installed inside the inlet pipe 11 can filter the incoming liquid, preventing impurities from entering the interior of the main body 2. When cleaning the filter screen 18 after long-term use, the abutment bolt 16 can be removed from the outer surface of the screw 15, and then the connecting frame 14 can be pulled. This causes the receiving plate 17 fixed on the left side of the connecting frame 14 to move the filter screen 18 synchronously with the connecting frame 14 inside the rectangular groove 13, allowing the filter screen 18 to be removed from the interior of the inlet pipe 11 for cleaning.

[0029] When performing explosion protection, the airflow generated by the main body 2 is connected to the air groove 6 inside the connecting block 5, allowing the airflow to enter the interior of the protective airbag 7, inflating the protective airbag 7. This prevents damage caused by the change in position when the main body 2 explodes. In use, the stability of the protective airbag 7 can be ensured by the plug-in plate 8 and the fixing bolts 9, thus facilitating the stable use of the whole system for protection.
