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 at the rear and a dust collection case 3 at the front.

The blower case 2 has a handle 4 on the upper part and rear wheels 5 on both sides of the lower part, and the dust collection case 3 has a handle 6 on the upper part and a freewheel 7 on the lower surface.

The dust collection case 3 has a protrusion 8 at the rear end of the lower part that engages with a receiving part 9 at the front end of the blower case, and a clamp 10 provided at the rear end of the handle 6.
By engaging the front end of the handle 4, the blower case 2
connected to.

The blower case 2 incorporates an electric blower 11 and a cord reel 12, and has an air intake port 1 at the front of the electric blower 11.
It has 3.

The dust collection case 3 is open at the front and rear sides, and the rear side has a connection port 14 connected to the suction side of the blower case 2, and the front side has a dust discharge port 15.

A filter unit 16 is fitted into the connection port 14 .

The filter unit 16 has a base frame 17, and a sealing member 18 is attached around the base frame 17 so as to be in close contact with the front surface of the blower case 2 and the inner peripheral surface of the dust collection case 3.

Reference numeral 19 denotes a cylindrical filter attached to the front surface of the base frame 17 so as to protrude toward the dust discharge port 15. The filtration section 21 is constructed by stretching a resin net.

A secondary filter 22 is arranged inside the -order filter 19 .

The secondary filter 22 is made by bending a resin-processed nonwoven fabric 23 into a cylindrical cross-sectional shape as shown in FIG. 2, which is sandwiched between a front end plate 24 and a rear end plate 25.

The secondary filter 22 is rotatably supported by inserting a shaft 26 protruding rearward from the center of the front end plate 24 into a bearing portion 27 of the base frame 17.

A handle 28 is fixed to the rear end of the shaft 26.

29 is a dust removing body fixed to the outer surface of the bearing part 27, and has a plurality of elastic arms 30 projecting radially.
is shallowly engaged between the folds of the nonwoven fabric 23, and when the secondary filter 22 is rotated by the handle 28, the elastic arms 30
The folds of the nonwoven fabric 23 are flicked one after another to cause dust attached to the surface to fall.

The rear end plate 25 has a donut shape, and the secondary filter 2
A sealing member 31 that contacts the base frame 17 is attached around the periphery of the sealing member 31 to communicate the inside of the housing 2 with the outside.

An appropriate number of ventilation holes 32 are formed in the base frame 17 at locations surrounded by the sealing member 31.

- A fine dust reservoir section 33 for receiving fine dust falling from the secondary filter 22 is formed at the lower part of the secondary filter 19.

A fine dust discharge port 34 is formed at the front end of the fine dust collecting portion 33, and is closed from the outside with a lid 35 having a pivot point at the upper end.

Reference numeral 36 denotes a lid for closing the dust outlet 15 from the outside, which is connected by a shaft 38 to a bearing piece 37 protruding from the handle 6, and is constantly biased in the closing direction by a screw spring 39 wound around the shaft 38. There is.

A seal member 40 is attached to the mouth edge of the dust outlet 15,
Good adhesion with the lid body 36 is achieved, and the impact noise when the lid is closed is softened.

A hose connection port 41 is provided on the lid body 36.

Reference numeral 42 denotes an arch-shaped movable sweeper arranged around the primary filter 19 so that its inner edge is close to the filter section 21.
It is pivotally supported by a pair of bearing pieces 43 protruding from the inner bottom surface of the dust collection case, and is rotatable about a pivot point 44.

The upper surface of the second filter 19 is an arcuate surface centered on the pivot point 44 in accordance with the locus of movement of the inner edge of the sweeper.

45 is a plate-shaped link connecting the free end of the sweeper 42 and a bracket 46 protruding from the back surface of the lid body 36;
As shown in the figure, the width is approximately equal to the width of the dust collection case 3, and when the lid body 36 is closed, the sweeper 42 is
As shown in the figure, it is held at a position after the filter section 21.

Next, the action will be explained.

When a hose is connected to the hose connection port 41 and the electric blower 11 is operated, air flows into the dust collection case 3.

Among the dust contained in the incoming air, large particles are filtered by the primary filter 19, and fine dust not captured by the secondary filter 19 is filtered by the secondary filter 22.

When the amount of accumulated dust increases and it is time to dispose of the dust, the dust collection case 3 is separated from the blower case 2, and the fine dust is first dropped from the secondary filter 22 by turning the handle 28.

Next, as shown in FIG. 3, when the lid body 36 is opened, the link 4 is opened.
5, the sweeper 42 is pulled out, and the sweeper 42 scrapes off the dust layer adhering to the filter section 21.

If the dust outlet 15 is turned downward with the lid body 36 open, the lid 35 will also open and coarse dust and fine dust can be thrown away at the same time.

As described above, the vacuum cleaner of the present invention has a dust outlet covered with a lid on one side of the dust collection case, and a movable sweeper is installed around the cylindrical filter that protrudes from the back of the case towards the dust outlet. and the sweeper is connected to the lid so that when the lid is opened, the sweeper moves to scrape off dust from the outer surface of the filter and immediately discharge it from the dust outlet. Therefore, the dust can be disposed of hygienically without touching the filter, which has a great practical effect.
