Abstract

An automatic exhaustion on-off device for a fume discharging pipe is connected between a fume discharging port of a fume discharging machine and the fume discharging pipe of the fume discharging machine and comprises a connecting pipe with two ports communicated up and down, a positioning piece fixed at the inner edge of the pipe wall of the connecting pipe, and two dimidiated movable separation blades arranged on the internal pipe diameter of the connecting pipe in a matched manner, wherein, the inner side edges of the two movable separation blades are movably pivoted relative to each other; when the two movable separation blades compress and lean against the positioning piece through downward swinging under the action of the weight of the separation blades, the fume discharging machine is in a normally-closed state, which is a horizontal close state; when the fume discharging machine works and is forced to discharge the oil fume and waste gas, the fume discharging machine is in a vertical open state through the upward swinging of the two movable separation blades by the aid of the wind, so as to discharge the oil fume and the waste gas through the connecting pipe and the fume discharging pipe. Therefore, through the on-off device provided by the utility model, outdoor strong wind, oil fume and waste gas, undesirable odor and dust are prevented from invading into the fume discharging machine and the indoor kitchen, thereby ensuring the quality and safety sanitation of household life.
