Claims

[Scope of Claim for Utility Model Registration] One end communicates between the suction side of the electric blower and the dust collection chamber inside the vacuum cleaner body, and the other end has a valve seat that has a valve opening in the center that communicates with the atmosphere side. A transparent indicator pipe is provided, and a display part that is slidably housed in the indicator pipe in the axial direction and opens and closes the valve port of the valve seat, and a display part that shows the usable state and a display part that shows the state where dust disposal is required are color-coded. and a spring that biases the pointer toward the valve seat, and the pointer has a communication hole through which the air flowing into the indicator pipe from the valve port passes, near the tip on the inside of the vacuum cleaner body. a first pointer member having a first pointer member and forming a display section in a usable state;
and a second pointer member that is fitted to the valve seat side of the pointer member and forms a display section indicating that dust disposal is required, and the second pointer member is made of a soft material. Vacuum cleaner dust indicator.
