Description

[Detailed Description of the Invention] The present invention provides a vacuum cleaner that can easily remove dust.

An embodiment of the present invention will be described below with reference to the drawings.

The vacuum cleaner main body 1 has a blower case 2 in the rear half and a dust collection case 3 in the front half.

The blower case 2 houses an electric blower 4 and a cord reel 5, and has a handle 6 on the top and rear wheels 7 on both sides of the bottom.

The dust collection case 3 has a handle 8 on the upper part and a free front wheel 9 on the lower surface, a protrusion 10 at the lower end of the rear engages with a receiving part 11 protruding from the blower case 2, and a spring-loaded clamp 12 provided at the rear of the handle 8. is connected to the blower case 2 by engaging with the front part of the blower case side handle 6.

The dust collection case 3 has openings on the front and rear sides, with the front opening serving as the dust outlet 13 and the rear opening serving as the blower case 2.
It is used as the connection port 14 to the

Reference numeral 15 denotes a lid for closing the dust outlet 13 from the outside, which is pivotally supported by a shaft 17 on a bearing piece 16 protruding from the handle 8, and biased in the opening direction by a torsion spring 18 wound around the shaft 17.

A clamp 19 that engages with the free end of the lid 15 is attached to the lower surface of the dust collection case 3, thereby holding the lid 15 in the closed position.

The lid body 15 has a hose connection port 20 and a dust discharge port 1.
An annular sealing member 21 is attached to the inner surface of the housing 3, and the annular sealing member 21 is in close contact with the mouth edge of the housing 3.

22 is a cylindrical filter that protrudes from the back of the dust collection case 3, that is, from the connection port 14 toward the dust discharge port 13;
A filtering section 25 is formed by stretching a filtering material over a plurality of windows 24 formed on the outer peripheral surface of the cylindrical frame 23.

A flange 26 is formed at the rear end of the frame 23, and a sealing member 27 that fits into the connection port 14 and is in close contact with the front surface of the blower case 2 is wrapped around the flange 26.

Reference numeral 28 denotes an annular sweeper that is slidably fitted to the outside of the filter 22 with its inner edge close to the outside. The flange portion 30 has an outer diameter slightly smaller than the inner diameter.

The sweeper 28 is connected to the flange 26 of the filter 22 by a pair of left and right compression coil springs 31, and is pushed out to the front end of the filter 22 by the elastic restoring force of the spring 31 when no force is applied from any other source.

On the other hand, a pair of left and right protrusions 32 are formed on the inner surface of the lid body 15,
When the lid body 15 is closed, the sweeper 2
8 to near the rear end of the filter 22.

Next, the action will be explained.

When a hose is connected to the hose connection port 20 and the electric blower 4 is operated, air flows into the dust collection case 3, and the dust carried by the air is filtered by the filter 22.

When the amount of accumulated dust becomes large, the dust collection case 3 is separated from the blower case 2 and carried to a dust disposal area, and the clamp 19 is removed and the lid 15 is opened as shown in FIG.

Then, the sweeper 28 moves forward toward the dust outlet 13 due to the elastic restoring force of the spring 31, and sweeps up the dust adhering to the filter section 25 and drops it forward.

Therefore, without touching the filter 22, the filtration section 25
is to be cleaned, and the scraped dust can be immediately thrown away from the dust outlet 13.

As described above, the vacuum cleaner of the present invention includes a dust collection case with a dust discharge port on one side, and a cylindrical filter having a filtration part on the outer peripheral surface protruding from the back of the dust collection case toward the dust discharge port. a sweeper which is slidably disposed with its inner edge close to the filtration portion of the filter and is provided with an elastic restoring force by a coil spring in the direction of the dust discharge port; and a sweeper which opens and closes the dust discharge port. Since the lid body has a projection on the inner surface that pushes the sweeper inward against the restoring force of the coil spring, the sweeper immediately moves toward the dust outlet when the lid is opened. It moves to peel off dust attached to the outer periphery of the filter and sweep it toward the dust outlet, which has the advantage that the filter can be cleaned and the dust can be disposed of at the same time.
