台形状とされたこと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 a dust collection motor, and a communication port that communicates the mechanism chamber and the dust collection chamber,
A ventilation path is formed in the dust collection chamber that communicates the space between the dust collection bag and the mechanism room with the outside of the main body, and the ventilation path is provided with a negative pressure of a certain level or more in the space due to clogging of the dust collection bag. In the vacuum cleaner, the vacuum cleaner is equipped with a negative pressure valve device that introduces outside air into the space when the vacuum cleaner is cooled, and the negative pressure valve device includes a negative pressure valve that opens and closes the air passage, and a negative pressure valve that biases the negative pressure valve in a closing direction. The compression coil spring has a truncated cone shape with a diameter gradually increasing from one end to the other so that each coil part can be fitted into an adjacent coil part. A vacuum cleaner.
