[0063] In summary: when the heat work device body 100 is used for operation, if the internal power module 109 short-circuits and ignites, smoke is generated inside the heat work device body 100, the smoke sensor 107 detects the smoke and sends a signal to the alarm 101, the alarm 101 emits an alarm sound to remind the operator, the operator hears the alarm sound and quickly leaves the heat work device body 100 and evacuates to a safe position, when the open flame in the heat work device body 100 melts the fuse 304, the extension spring 303 pulls the sliding block 307, the second rack 405 and the third rack 406 to move, the third rack 406 moves downward to drive the first gear 404 to rotate counterclockwise, the rotation of the first gear 404 drives the first rotating shaft 401 to rotate, the rotation of the first rotating shaft 401 drives the first bevel gear 407 to rotate counterclockwise, the counterclockwise rotation of the first bevel gear 407 drives the second bevel gear 408 to rotate clockwise, the clockwise rotation of the second bevel gear 408 drives the second rotating shaft 412 to rotate clockwise, and in turn drives the sprocket 410 to rotate, and through the transmission of the chain 411, the other sprocket 410 is driven to rotate, and in turn drives the third rotating shaft 413 to rotate, the rotation of the third rotating shaft 413 drives the tooth column 414 to rotate clockwise, and in turn drives the push rack 415 to move towards the heat work device body 100, so that the cover plate 501 moves towards the heat work device body 100, the clamping rod 511 gradually contacts the clamping device 504, and the original position spring 507 is compressed.

[0064] When the open flame in the heat work device body 100 is extinguished, when the second rack 405 moves downward, the first gear 404 engaged with the second rack 405 rotates, the rotation of the first gear 404 drives the first rack 402 to move upward, the upward movement of the first rack 402 drives the first steel wire rope 302 to move upward, the upward movement of the first steel wire rope 302 pulls the partition plate 605, so that the connecting rope 604 is pulled off, the partition plate 605 moves out of the guide frame 600, the N pole of the second magnet 602 contacts the N pole of the first magnet 601, forming a repulsive force, pushing the second magnet 602 to move and hit the moving rack 701, the movement of the moving rack 701 drives the second gear 702 to rotate, the rotation of the second gear 702 drives the valve 202 to be opened, the high-pressure carbon dioxide in the steel cylinder 200 enters the conduit 201, and then enters the horizontal pipe 203, and finally is discharged from the horizontal pipe 203 into the heat work device body 100, to extinguish the open flame on the power module 109.

[0065] When the harmful gas inside the operation device body 100 after the fire extinguishing is discharged, by starting the pump body 106 and the filter 105, the toxic gas at the bottom and top of the operation device body 100 respectively enters from the annular pipe 108 and the exhaust pipe 102, and finally is filtered through the filter 105, realizing the filtering of the harmful gas.

[0066] The fire operation device body 100, the alarm 101, the smoke sensor 107, the filter 105 and the pump body 106 can be purchased in the market, which belongs to mature technology in the field and has been fully disclosed, so the description is not repeated here.

[0067] Although the embodiments of the present application have been shown and described, it can be understood by those skilled in the art that various changes, modifications, replacements and variations can be made to the embodiments without departing from the principles and spirits of the present application, and the scope of the present application is defined by the appended claims and their equivalents.
