を特徴とする電気掃除機。 A vacuum cleaner body is formed with a dust collection chamber that removably stores a dust collection bag, a mechanism chamber having an electric blower, and a communication port that communicates the mechanism chamber and the dust collection chamber,
A ventilation passage is formed in the dust collection chamber to communicate the space between the dust collection bag and the mechanism room to the outside of the main body, and the ventilation passage is provided with a negative pressure that exceeds a certain value in the space due to clogging of the dust collection bag. In the vacuum cleaner, the safety valve device includes a safety valve that opens and closes the air passage, and a compression coil spring that biases the safety valve in a closing direction. A vacuum cleaner characterized in that the outside air contact surface of the safety valve is formed in a concave shape to increase the operating pressure of the safety valve device.
