Description

[Detailed description of the invention] (Industrial application field) The present invention relates to a small vacuum cleaner such as a hand type vacuum cleaner.

(Prior art and its problems) Recently, large vacuum cleaners such as those that run on the floor use special paper bag filters as filters.

The mainstream trend is to remove the paper bag filter and dispose of it when disposing of the dust, making it easy to dispose of dust, but such items require the purchase of a special paper bag filter. It wasn't very economical. However, with large vacuum cleaners, the volume of the dust collection part can be increased, and the dust collection volume of one paper bag filter can also be increased, so they can be used for a relatively long period of time.
The number of sheets consumed was kept low, and dust disposal was easy, so I didn't feel much of an economic burden.

However, when this type of dust treatment using a paper bag filter is applied to a small vacuum cleaner such as a hand-held vacuum cleaner, the volume of the dust collecting section is small and it is necessary to empty the dust frequently.
This method has the drawback that the consumption of paper bag filters increases significantly, resulting in a large economic burden.

(Object of the Invention) The present invention has been made in view of the above points, and it is an object of the present invention to use a soft, non-bag-like paper that is breathable, such as tissue paper, which is always available in ordinary households, as a filter. This makes it easy to dispose of dust, and
To provide a small vacuum cleaner that can reduce economic burden.

(Structure of the Invention) The present invention is characterized in that a breathable, soft, non-bag-like paper is fixed to the peripheral edge of the dust collection i, and the air flow sucked by an electric blower passes through the dust collection i. In this way, the paper is configured to act as a filter, thereby achieving the intended purpose.

(Example) An example of the present invention shown in the drawings will be described in detail below.

The illustrated small vacuum cleaner is a rechargeable hand vacuum cleaner.
1 is a vacuum cleaner main body, which has a dust collection section 2 that opens on the front end face formed in the front part, an electric blower 3 and a rechargeable battery (not shown) such as a lead-acid battery built in behind this, and an upper part. is equipped with a handle 4.

Reference numeral 5 denotes a bag-shaped main filter made of cloth, and its mouth is provided with a mouth frame 6 made of an elastic material such as rubber and having a substantially cross-sectional shape, and this mouth frame 6 is fitted into the opening of the dust collecting section 2. Accordingly, it is arranged in the dust collecting section 2. Reference numeral 7 denotes a front lid having a suction port 8, and an engaging part 9 is formed at the lower part of the back side thereof, and a claw IO is formed at the upper part, and the engaging part 9 is engaged with the protrusion 11 of the vacuum cleaner and the main body 4. After that, hook the claw 10 onto the clamp lever 12,
Attach a guard to close the opening of the dust collecting section 2.

The clamp lever 12 has one fixed end and a free end that uses its own flexure to engage and disengage from the claw IO, and is a push button for operating the 13-piece clamp lever 12.

14 is a soft, non-bagged paper with air permeability, such as tissue paper, and the central part of the tissue paper 14 is pushed into the inside of the main filter 5, and the remaining peripheral part is folded back to the outside of the mouth frame 6. It is fixed between the mouth frame 6, the inner surface of the front lid 7, and the opening edge of the dust collecting section 2. This is a backing provided on the inner surface of the front lid 7.

In the above configuration, first, the tissue paper 14 is placed on the mouth frame 6 of the main filter 5, the center part is pushed inward with a finger, etc., and the tissue paper 14 is placed on the inner surface of the main filter 5, and then the peripheral part is placed on the mouth frame 6. Fold it back to the outside, and in this state, place the main filter 5 inside the dust collecting section 2 using the mouth frame 6, and then close the opening with the front lid 7 (as shown in the first figure).
.

In this state, the peripheral edge of the tissue paper 14 is sandwiched between the backing 15 of the front lid 7 and the mouth frame 6 as shown in the second figure, so when the tissue paper 14 is folded over at that part and unevenness occurs, the backing 15 Due to this function, air leakage due to unevenness does not occur. Also, since the five-port frame 6 is made of an elastic material, the distance between the one-port frame 6 and the opening edge of the dust collecting section 2 is
Air leakage due to the unevenness described above does not occur.

As described above, when the electric blower 3 is operated with the tissue paper 14 and the main filter 5 installed, the dust-containing suction air flow enters the dust collecting section 2 from the suction port 8 and the tissue paper 14. The air passes through the main filter 5 in order and is filtered there, and then becomes clean air, passes through the fan section of the electric blower 3, and is discharged outside the machine from the exhaust port.

Therefore, the tissue paper 141-j collects relatively coarse dust in the suction air flow, and the main filter 5
-14, which serves as a pre-filter, is taken out together with the main filter 5, rolled up with tissue paper 14 to enclose the dust inside, and then disposed of. Since the tissue paper 14 is always kept, easily available, and inexpensive, there is no need to feel an economic burden even if it is disposed of after every cleaning, and high suction power is always achieved by replacing it with a new one every time the cleaning is done. This is especially advantageous for rechargeable type devices that have a low power supply voltage and cannot have strong suction power.

Furthermore, the main filter 5 has a tissue paper 14
(7) Due to its presence, clogging becomes less likely to occur.

The number of dust removal operations can be drastically reduced compared to when the tissue paper 14 is not used.

In the above embodiments, tissue paper, which is the most readily available and always available in general households, is used as an example of breathable, soft, non-bag-like paper. It suffices if it is similar.

Furthermore, as long as the vacuum cleaner is small, it is not limited to a rechargeable type, and may be powered by a dry battery, an automobile battery, a 100-square-meter alternating current, or the like, and is not limited to a hand-held type.

Further, the method of attaching a piece of paper is not limited to that of the above embodiment, but any method may be used as long as it can securely attach at least the peripheral edge and maintain a predetermined state against suction force.

Other 1 The present invention is not limited to the embodiments described above and shown in the drawings, but can of course be implemented with appropriate modifications within the scope of the gist.

(Effects of the Invention) As described above, according to the present invention, tissue paper can be used with high suction power at all times.

It is useful in practical terms.
