s4: when the moving plate (3) moves up and down in a reciprocating mode, the moving plate can rub the friction rod (15) to generate heat, the heat conducting column (22) transmits the heat into the second cylinder (19), alcohol in the heat conducting column is volatilized to generate gas, the second moving rod (20) is further pushed to move, the switch (23) is turned on, the heat radiating fan (17) is rotated to blow and radiate the sensor body (6), after the sensor body is cooled, the alcohol is liquefied, the second moving rod (20) retracts, the switch (23) is turned off, and the heat radiating fan (17) is turned off, so that the heat radiating is circulated, the sensor body (6) is periodically radiated, the sensor body is enabled to work at a proper temperature all the time, and the service life of the sensor body (6) is effectively prolonged.
