Description

[Detailed description of the invention] (b) Industrial application fields The present invention relates to a small portable vacuum cleaner.

-) Conventional technology For example, a small cordless portable vacuum cleaner disclosed in Japanese Patent Application Laid-Open No. 58-160555 has a dedicated filter device installed inside the dust box attached to the front of the main body. However, the filter device must be cleaned every time the garbage is disposed of, which is cumbersome to handle and requires a dedicated filter device.

Therefore, the present applicant has already proposed a small portable vacuum cleaner (see Utility Model Application No. 168191/1982) that uses paper filters such as tissue paper that are inexpensive and easily available. As shown in Figure 5, this thing has a dust collection recess of course 181! A paper filter ■ is placed between the paper filter and the paper filter.
1) protrudes from the dust-containing lid (2), which is unsightly, and the peripheral edge (29a) may become dirty or damaged.

f→ Problems to be Solved by the Invention The small portable vacuum cleaner of the present invention is capable of attaching an inexpensive and easily available paper filter without making it look unsightly, and also makes the attachment process easy. This is what I did.

B) Means for Solving the Problems The small portable vacuum cleaner of the present invention includes a main body having an upwardly opening dust collection recess at the front and a built-in fan motor at the rear;
A dust collection case having an upper opening and having a filter part and installed in the storage recess, a filter part body having a suction port and a paper holding rib and equipped in the dust collection case, and the filter part housing. , it is characterized by comprising a paper filter attached between the body and the storage case, and a lid body which is pivotally attached to the body and closes the downward direction of the recess at the back of the writing station. (e) When the working paper filter is attached, the paper filter is placed in an expanded state inside the housing case by the filter body, and
Therefore, when the peripheral end protrudes directly above the filter body, this peripheral part is folded back and the upper opening of the dust collection recess is covered with the lid, so that it is covered with the lid. The end does not protrude from the lid. Further, the dust sucked in from the suction port accumulates on the paper filter, and the paper filter is discarded together.

(f) Example (1) is a main body of a small-sized vacuum cleaner, which has a front wall (3) equipped with an intake hole (2) at the front, and a rear handle (4). and a front lower bottom (6) provided by extending the bottom part of the storage part (5) forward.
) by extending a side wall consisting of left and right two-divided side plates (7a, 7b) and a front plate (8) upwardly from the periphery of the first opening for fitting the suction port ( 9)
a dust collection recess t10) configured in the shape of an open case with
This has a built-in rechargeable battery (11) and the air intake hole (
2) At the rear, the fan motor (12) is the fan (12m)
is disposed so as to face the intake hole (2). Rani (131) is a bush type power switch disposed inside the equipment storage section (5).

The α stand is a dust collection case that is removably installed in the station back recess α0 and has an upper opening and a second opening Oω for fitting the suction port in the front. lal
When housed in the recess (10), the mesh filter part α is located below the upper opening edge of the recess (10) with a predetermined gap from the lower bottom (6) and the side plate (7λ') (7b).
It has a mouth on its bottom and side.

αη is a filter part mounting body installed in the dust collection case 04), and this holding body α is a pair of parts that enters into the station back case aω on the back side of the board marked a that covers the upper opening of the dust collection case circle. A rib side stop for paper pressing is planted downward, and this substrate α comb is inserted into the first and second openings (91) for fitting the suction port.
There is a cylindrical plate that protrudes from G5) and guides the dust to the dust collection case 0J below this protruding part. Also, (2) is a synthetic rubber plate that covers the outlet side of this suction port (■) so that it can be opened and closed. It is a made-of-white flap.

There is a dust collection lid body that covers the lower part of the dust collection recess αα of the front body (1) and the suction port at the filter body α. ) is rotatably attached to the upper part of both sides via a screw mechanism, and has left and right hanging pieces (25) that cover the periphery of the upper opening.
a) (25b) at both ends.

■ is a paper filter made by using commercially available tissue paper or kitchen paper as is, and this paper filter ■ is a dust collection case 0 installed in the dust collection recess (10).
4) Place the central part on the upper opening, and insert the filter part holder (1) into the dust collection case (14) to remove the paper presser rib 0 of the filter part holder opening η.
909 is introduced into the dust storage case 04) with its central portion expanded into the dust storage case 04) to have a wide dust storage space, and the filter body 0'7) and the dust storage case 0'7) are connected to each other. It is sandwiched between the case and the round. Then, the peripheral edge of the paper fuselter (26) is connected to the substrate α of the filter part body (17).
By folding back to the mark surface and closing the dust collecting lid (support), the peripheral end portion (26a) is held between the filter part cover αη and the lid (support). Therefore, the paper filter is stored in the dust collection case 0 with its peripheral end (261) not protruding from the dust collection lid (2).

Then, hold the handle (4) and turn on the power switch (13).
If you turn on the fan motor 0 with the rechargeable battery 01) power
z is driven, and therefore the dust is sucked in from the suction port ■ and collected by the paper filter ■. At this time, the paper surface of the paper filter ■ is in close contact with the inside of the station back case λα. The shape is maintained and reinforced by the dust collection case circle, and since there is a gap between the dust collection case circle and the dust collection recess α0, the filter has a wide filter area and can efficiently collect dust.

When disposing of garbage, open the dust container lid by rotating it from the dust storage recess side, open the peripheral end (26a) of the paper filter (2), remove the filter holder (17+), and open the peripheral end (26a) of the paper filter (2). 26a), take out the garbage together with the paper filter (2), and dispose of it.

(G) Effects of the Invention According to the present invention, the paper filter can be easily installed in the storage case by the filter holder, and the end portion of the paper filter can be stored between the filter holder and the dust storage lid. The paper filter does not protrude from the dust cover body, so the paper filter can be installed without being visible from the outside with a simple installation process.
