[0031] The working principle and use process of the utility model are as follows: the intake passage heating device of the ultra-low temperature starting gasoline engine is installed before use. The main frame 101 can be closed at the air inlet end of the intake passage, the main frame 101 is fixed by penetrating the inside of the mounting hole 102 through the bolt, so that the heating device main body 100 is fixedly mounted. After the heating device main body 100 is fixedly mounted, the terminal 105 is connected to the external lead wire to be electrified, and the heating element 103 is heated through the connecting end 104 after being electrified. The gas is inhaled after being heated by the heating device main body 100 when the air is inhaled in the intake passage, so that the temperature is improved, and the gasoline engine is started smoothly.

[0032] Then, after the heating device body 100 is fixedly installed, when the bolt passes through the mounting hole 102 and is fixed, the bolt contacts the surface of the fixing plate 1027. The tool is then engaged in the internal hexagonal socket 1026 to drive the threaded rod 1023 to rotate. The top end of the threaded rod 1023 is rotated in place inside the moving frame 1022, and the bottom end of the threaded rod 1023 is rotated inside the internal threaded hole 1025. The threaded rod 1023 is rotated open to push out the moving frame 1022. When the moving frame 1022 is pushed out, it slides inside the sliding hole 1021, driving the moving reinforcing plate 1028 to clamp and fix it on the surface of the bolt. The tightening nut 1024 is rotated again to fix the threaded rod 1023. Thus, after the bolt is rotated and installed, the heating device body 100 is reinforced and tightened. When the heating device body 100 is installed on the gasoline engine for a long time and is subjected to vibration, it is not easy to loosen. The installation is more stable, and the stability of the heating device body 100 when it is installed on the gasoline engine intake is enhanced.

[0033] Finally, when the heating device body 100 has been installed and used for heating for a long time, and dirt adheres to the surface of the heating element 103 during air intake, the heating device body 100 can be disassembled. The sliding plate 1031 is held to drive the connecting plate 1032 and the scraper 1033 to slide. The scraper 1033 slides and contacts the inner surface of the heating element 103 to scrape and clean it. The cleaning is convenient and does not easily reduce the heating effect due to dirt adhering to the surface of the heating element 103. It is convenient to clean and effectively heats and starts the gasoline engine during air intake. Using matching cleaning tools will not easily scratch or damage it. When not cleaning, the sliding plate 1031 is closed at the bottom of the main frame 101. The external threaded post 1036 passes through the interior of the hollow plate 1035. The internal threaded fastening cylinder 1034 is rotated on the outer surface of the external threaded post 1036 to fix the sliding plate 1031 in place, which is convenient for fixed placement when not cleaning.
