着されていないことを報知する。(Function) In the vacuum cleaner of the present invention, when the dust collection bag is not installed in the dust collection chamber, the biasing force of the second spring is made larger than the biasing force of the first spring, so that the detection object detects the The part is biased by the second spring and protrudes into the dust collection chamber, and the actuating part of the notification body that comes into contact with the engaging part is pressed against the first spring, separating the notification body from the valve hole. The valve hole is opened. That is, the movement of the notification body of the indicator notifies the user that the dust collection bag is not attached. Furthermore, when the electric blower is driven in this state, outside air flows directly into the dust collection chamber through the indicator, and the noise generated by the suction air flow at this time also alerts that the dust collection bag is not attached.

が装着されていることを報知する。 Furthermore, when the mouth frame of the dust collection bag is attached to the dust collection chamber, the mouth frame comes into contact with the protruding end of the detection part of the detection body, presses the detection part against the second spring, and moves the notification body. As a result, the engagement between the engagement part of the notification body and the actuation part of the notification body is released, so the notification body is pressed by the first spring, closes the valve hole of the cylinder, and opens the inside of the communication passage. Block the airflow. In this state, the notification body moves to a position where the display hole cannot be seen and notifies that the dust collection bag is attached.

る。 When the dust collection bag becomes clogged due to dust accumulation during cleaning, the suction force from the suction port decreases, and the negative pressure inside the dust collection chamber increases, and this negative pressure is applied to the first spring. When the force becomes larger than that of the first spring, the notification body is attracted toward the inside of the dust collection chamber against the biasing force of the first spring, and the notification body opens the valve hole. Since this notification body moves to a position where it can be seen through the display hole, it notifies the user that the dust collection body is clogged.
In addition, outside air flows directly into the dust collection chamber through the indicator, and the noise generated by the suction airflow at this time notifies that clogging has occurred.

電気掃除機。[Scope of Claims] 1. An electric blower room in which an electric blower is installed, a dust collection chamber that communicates with the suction side of the electric blower room and has a suction port, and a dust collection chamber that is removably installed in the dust collection chamber and that is inserted into the opening. A dust collection bag having a mouth frame for mounting, an indicator that communicates between the inside and outside of this dust collection chamber and indicates whether the dust collection bag is clogged due to a pressure difference between the outside and outside of the dust collection chamber, and a dust collection bag inside the dust collection chamber. a detection body for detecting whether or not a bag is attached; the indicator includes a cylinder having a communication passage that faces the display hole and communicates with the inside and outside of the dust collection chamber and has a valve hole formed in the middle part; The cylinder has an actuating part that is slidably provided in the cylinder and extends through the valve hole and projects from the valve hole, and is biased by a first spring in a direction to close the valve hole. an indicator that is slid by negative pressure against the biasing force of the first spring, and the detector includes an actuating part that is provided along the indicator and protrudes from the valve hole of the indicator. The second spring is biased in the direction of protruding into the dust collection chamber by the engaging portion engaged with the second spring, and the mouth frame of the dust collection bag attached to the dust collection chamber resists the second spring. A vacuum cleaner comprising: a detection part that is slid by the second spring, and the biasing force of the second spring is greater than the biasing force of the first spring. 2. The vacuum cleaner according to claim 1, characterized in that a handle is provided in the front part of the dust collection chamber of the vacuum cleaner body, and an indicator and a detection body are built into the handle.
