Summary: | The invention provides a dustproof device of a combustible gas detection probe and a combustible gas detector and relates to combustible gas detection equipment. The dustproof device is characterizedin that a pipe barrel is sleeved on a probe shield, vent holes are formed on an upper end of the pipe barrel, an air inlet is formed on a lower end of the pipe barrel, inner rotation blades which spirally extend are arranged on an inner wall of the pipe barrel, so the gas entering the pipe barrel can spirally rise along the internal rotation blades, in the spiral ascending process, the gas generates the rotary scouring effect on the probe shield, the opportunity that the combustible gas in the air is in contact with the probe shield is increased, moreover, impurities such as sand and dust blocked on the probe shield can be impacted, so a blocking problem of the probe shield is greatly reduced or even avoided, the dustproof effect is improved, interference of the impurities such as sand anddust on reactions such as |
