EXAMPLES Hereinafter, the present invention will be explained based on the illustrated embodiments.
The figure is a perspective view of the same. In the figure, 1 is a cylinder-type self-propelled vacuum cleaner, and a suction hose 4 is attached to a suction port 3 of a main body 2, which can be attached or detached with one touch.

A cartridge-type dust collection unit 5 is detachably attached to the rear of the main body 2, and a dust collection bag (not shown) is installed inside this. An exhaust port 6 is provided for discharging the exhaust gas that exits through.

A dust removal device 7 according to the first embodiment of the present invention is detachably attached to the exhaust port 6.

The dust removal device 7 includes an outer case 9 that can run on wheels 8, a first filter 10 built into the outer case 9, and a second filter 11 located after the first filter 10. , it has a connecting pipe 12, preferably in the form of a flexible tube, that connects the exhaust port 6 and the first filter 10.

Specifically, the outer case 9 is provided with outlet ports 13 and 14 for the first filter 10 and the second filter 11, and the outlet port 14 is provided with an opening/closing lid 15.

The first filter 10 has a relatively thin plate shape and can be inserted into the outlet 13 from above and held upright facing the connecting pipe 12 by left and right holding members (not shown) and a lower holding member 16. It's so bad. The first filter 10 and the connecting tube 12 are airtightly connected to a trumpet-shaped dispersion tube 17. Further, on the rear side of the first filter 10, a collecting pipe 18 is provided.
are closely connected, this collecting pipe 18 collecting port 18a
A flexible guide tube 19 is connected to the .

By the way, this first filter 10 is a precision filter made of, for example, an air-permeable porous material, preferably can be used after re-cleaning, and is desirably strong in mechanical strength. For example:

(1) Non-woven fabric made from synthetic fibers or metal fibers.

(2) A plate made by stacking several layers of metal nets with different meshes and sintering them.

(3) A plate-shaped object made by sintering ceramic or other material through special processing.

(4) Sponge-like material made of polymer, preferably containing water.

(5) Cellulose or synthetic resin is dissolved in various solvents and the solvent is volatilized to form pores.

(6) Holes are formed by etching a synthetic resin film after irradiating it with neutrons.

(Synthetic resin is melted, discharged from a nozzle, and immersed in a coagulation bath to form a hollow fee gun.

Next, the second filter 11 is attached to the opening/closing lid 1 of the outer case 9.
In the cartridge-type liquid case 20, which is inserted by opening 5,
It has a configuration in which a liquid 21 is contained.

This liquid 21 is usually water, but other liquids may be used, and the level of the liquid 21 is set to be below the position of the collecting port 18B.

Openings 22 and 23 are provided at the front and back of the upper surface of the liquid case 20, and a guide tube 19 is passed through the opening 22, and the end of the guide tube 19 is in the liquid 21. Insert the exhaust pipe 24 to clean the air, then remove the exhaust pipe 24.
The end of the pipe is led out to the rear of the outer case 9. Then, connect the connecting pipe 12 to the exhaust port 6 in a one-touch manner, insert the first and second filters 10 and 11, and remove the vacuum cleaner 1.
Clean your room and hospital room.

By doing this, fine dust, mites, pollen, etc. that are not collected in the dust collection bag and come out of the exhaust port 6 will flow in the flow direction shown by the arrow in Figure 1 and will be passed through the first filter IO. υ Most of the dust is removed, and all fine particles are further removed by the second filter 11, and clean air is discharged from the exhaust pipe 24.

Note that since the water level of the liquid 21 is lower than that of the collecting port 18a, the liquid 21 does not move to the collecting pipe 18 side due to siphon action.

By the way, if the first filter 10 is clogged, it is sufficient to regenerate it by cleaning or the like and to replace the liquid 21 in the second filter 11.

In this embodiment, an inner lid 30 may be provided to prevent the liquid 21 from rippling.

Next, a second embodiment of the present invention will be explained with reference to FIG. Note that the same parts as in the first embodiment are denoted by the same reference numerals.

The second embodiment shows a case where the exhaust port 106 of the vacuum cleaner 100 has a lattice shape. Attachment 200 connected to is removably attached.

Incidentally, in both the first and second embodiments, the dust removal devices 11 and 111 are attached to a cylinder-type vacuum cleaner, but the dust removal devices 1.1 and 11 are attached to a pot-type vacuum cleaner.
1 may be installed.

Note that the outer case 9 may be fixed to the vacuum cleaner 1, 100 and the filter 10 of the box 1 may be directly connected to the exhaust port 6, 106 without using the connecting pipes 12, 112.

Further, the liquid 21 may be a deodorizing liquid. This deodorizing liquid has a deodorizing mechanism based on a free-lasocal reaction, and for example, one manufactured by Shitsuchan Sezz Co., Ltd. can be used. By using this product, you can reliably eliminate animal odors such as dogs and cigarette odors.

Effects As explained above, according to the present invention, the air containing dust mites, pollen, etc. coming out of the exhaust port of the vacuum cleaner is roughly removed by the first filter, and the second filter I used a filter to remove all the minute things, so
Compact and lightweight, it can be easily attached directly to any model of vacuum cleaner.
