Holds 24. However, by applying a slight pressure to the end of the rotation shaft 36 of the opening/closing lid 24 using the pressurizing protrusion 8a of the arm 8, the engagement between the protrusion 27 and the recess 28 is easily released, and the pressure is applied from the pressurizing protrusion 8a. By continuing to apply the pressure, the opening/closing lid 24 moves in the direction of covering the opening 22 of the cover 23, and completely covers the opening 22 as shown by the one-dot broken line in FIG.

29 is a gasket attached around the opening 12 of the inner lid 11, and is attached to the opening 22 of the inner lid 11 and the opening 23.
The surrounding area is sealed.

30 is a push button device attached to the front upper part of the dust collection case 3 near the rotation axis 36, and has a push button device 31 on the lower side facing the push portion of the stopper 16; Further, it has a lever 32 on the lower side that faces at least a part of the arm 8 excluding the support portion 8b, and the pressing piece 3
1.Lever 32 is the pressing part of the stopper.Arm 8
It is provided so as to be movable in the direction toward and away from, and is always urged by a spring 37 in the direction away from.

The lever 32 is inserted into a lever support hole 33 formed in the front of the dust collection case 3.

34 is a main filter with a dust removing device 35 built into the rear end of the dust collecting case 3, and a part of the dust removing device 35 is configured to be able to repel the protrusion 20 of the pre-filter container 18 and apply vibration. .

This device is constructed as described above, and when the electric blower 2 is operated, the dust sucked from the suction port 10 is captured by the disposable bag filter 21, and only clean air passes through the prefilter container 18 and the main filter 34. The air passes through the main body case 1 and enters the main body case 1, passes through the electric blower 2, and is discharged to the outside from an exhaust port (not shown) provided in the main body case 1. When the inside of the disposable bag filter 21 is full of dust, when the push button device 30 is pressed, the pressing piece 31 provided on the lower side presses the rotating shaft 36 side of the stopper 16, that is, the upper pressing part. , the stopper 16 moves downward against the spring 39, the hook part 16a at the lower end of the stopper 16 is disengaged from the locking protrusion 17 of the dust collection case 3, and the front cover 9 of the outer cover is released. The inner lid 11 becomes rotatable around the rotation shaft 36.

When the push button device 30 is further pushed in from this state, the lever 32 provided further below the push button device descends, and its lower end pushes the portion of the arm 8 other than the support portion 8b downward.

Therefore, the arm 8 moves downward around the support 8b against the urging force and slides on the opening/closing lid 24.
Since the pressurizing protrusion 8a of the arm 8 comes into contact with the side end 24b of the rotation shaft 36 of the opening/closing lid 24 and applies pressure, the engagement between the slight protrusion 27 provided on the opening/closing lid 24 and the recess 28 of the flap 23 is prevented. It comes off and then the pressure protrusion 8a
Due to the pressure applied by the opening/closing lid 24, the opening 22
, that is, in the direction of closing the opening 22 .

Then, as shown by the dotted line in FIG. 3, the opening 22
The opening/closing lid 24 covers the disposable bag filter, and the disposable bag filter is sealed. When the user stops pushing the push button device 30, the lever 32 returns upward under the force of the spring 37, and the arm 8, whose downward force is removed from the lever 32, returns upward due to the force and opens the opening 6. In other words, it moves to a position where it does not interfere with the removal of the disposable bag filter 21.

However, the opening/closing lid 24 that covers the opening 22 maintains a state in which the opening 22 is covered because no urging force is applied to the opening/closing lid 24 .

Therefore, when the front lid 9 is opened, the opening 22 provided in the opening 23 of the disposable bag filter 21 is completely covered by the opening/closing lid 24.
Dust will not leak out from this part.
Note that since the cover 23 is supported by the convex pin 7, it will not move when the opening/closing lid 24 is moved. Thereafter, the disposable bag filter 21 can be taken out of the dust collection case 3 and thrown away in a trash can or the like.

In the above embodiment, the opening/closing lid 24 is provided with a protrusion 27 and the opening 23 is provided with a concave shape 28.
However, if the opening/closing lid 24 is supported and fixed so that it slides on the cover 23 only when pressure is applied to the opening/closing lid 24 in the rotational direction on the shaft 24a that supports the opening/closing lid 24, the opening/closing lid 24 can be held. protrusion 27, opening paper 2
3 without the concave shape 28, the same effect can be achieved.

As mentioned above, this invention has an opening/closing lid on the opening of the disposable bag filter that can be opened and closed to cover the opening provided on the opening of the disposable bag filter, so that the garbage captured during dust disposal will not leak outside. In addition to enabling sanitary dust disposal without any hassle, the operation of the opening/closing lid is linked to the push button device for opening the front lid so that it can be operated from the outside, making dust disposal more efficient and improving operability. This has the practical effect of improving the performance.
