Description

DETAILED DESCRIPTION OF THE INVENTION (Field of Industrial Application) The present invention relates to a compact vacuum cleaner such as a 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, and when disposing of dust, the paper bag filter is taken out and disposed of as is, which facilitates dust disposal. The mainstream tends to be those that are easy to use, but these require the purchase of a special paper bag filter, which is not very economical. However, with large vacuum cleaners, the volume of the dust collection part can be increased, and the dust collection volume of the paper bag filter can also be increased, so they can be used for a relatively long period of time, the number of sheets consumed can be kept low, and the dust removal Due to its ease of use, I didn't feel any financial 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-mentioned problems, and uses breathable, soft, non-bagged paper, such as tissue paper, which is always available in ordinary households, on the suction side of the main filter. If the paper is installed and acts as a pre-filter, dust treatment can be easily carried out, the economic burden can be kept small, and the paper can be easily installed, reducing the number of cleanings of the main filter. The present invention provides a small vacuum cleaner that can significantly reduce the amount of waste.

(Structure of the Invention) The present invention is characterized in that a breathable, soft, non-bagged paper is attached to the suction side of the main filter, and a presser frame for fixing the peripheral edge of the patterned paper is attached to the main filter. It is designed to achieve 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. for·
・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. By doing so, it is arranged in the dust collecting section 2. Reference numeral 7 denotes a front lid having a suction port 8, and an engaging portion 9 is formed at the lower part of the back side of the front lid, and a claw 10 is formed at the upper portion of the front lid. By hooking the claw 10 onto the clamp lever 12, the opening of the dust collection section 2 is closed. The clamp lever 12 has one end as a fixed end, and uses its own deflection to engage and disengage the free end from the claw 10.
3 is a push button for operating the clamp lever 12.

14 is a soft, non-bagged paper having air permeability, such as tissue paper, and is disposed on the suction side of the main filter 5. A presser frame 15 is made of an elastic material such as rubber and fixes the peripheral edge of the tissue paper 14 between it and the mouth frame 6. This presser frame 15 has approximately the same shape as the mouth frame 6 and is located inside the mouth frame 6. It has a structure that fits into the mouth frame 6, and is integrally formed with the mouth frame 6 via the hinge part 16.

In the above configuration, first, the tissue paper 14 is attached to the mouth frame 6 of the main filter 5.
After pressing the center part inward and aligning it with the inner surface of the main filter 5 as shown in the third figure, press the presser frame 1.
This is done by closing the opening 5, fitting it into the mouth frame 6, and sandwiching and fixing the peripheral edge of the tissue paper 14 between them. Next, the main filter 5 with the tissue paper 14 attached in this way is placed in the dust collection part 2 of the vacuum cleaner body 1,
The opening is closed by the front lid 7 (as shown in the first figure).

In this state, between the inner surface of the front lid 7 and the opening edge 2' of the dust collecting section 2, there is a presser frame 15, an opening frame 6, and a tissue paper 1.
The peripheral edges of the frames 6 and 15 are sandwiched in a sequentially overlapping state, and the frames 6 and 15 are made of an elastic material such as rubber! 7, no air leakage occurs between the front cover 7 and the opening edge 2'.

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 passes through the tissue paper 14 and the main filter 5. The air passes through the air one after another and is filtered here, and then becomes clean air that passes through the fan section of the electric blower 3 and is discharged outside the machine from the exhaust port.

Thus, the tissue paper 14 is placed in front of the main filter 5 and acts as a pre-filter to collect relatively coarse dust in the suction air flow.

After cleaning, remove the front cover 7 and wrap it with tissue paper 14.
Take out the main filter 5 together with the presser frame 15.
Open it and use tissue paper 1 to cover the dust inside.
4 can be rolled up and disposed of as is, making it easy to dispose of dust.Moreover, it is economical to use tissue paper 14, which is readily available in general households and is inexpensive, even if it is disposed of every time it is cleaned. This is extremely advantageous especially for rechargeable types where the power supply voltage is low and the suction force cannot be increased.

Furthermore, the main filter 5 has a tissue paper 14
The presence of the tissue paper 14 makes it difficult to cause clogging, and the number of dust removal operations can be drastically reduced compared to the case without the tissue paper 14.

In the above embodiments, tissue paper, which is the most readily available and always kept in general households, is used as an example of breathable, soft, non-bag-like paper. Any other similar item may be used.

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

Further, the shape and material of the main filter are not limited to those of the above embodiments, and the presser frame may be integrated with the main filter or may be separate from the main filter.

In addition, the present invention is not limited to the embodiments described above and shown in the drawings, and would depart from the scope of the invention.

(Effects of the Invention) As described above, according to the present invention, paper such as tissue paper can be used as a filter to easily dispose of dust, and the economic burden is also reduced. It can be easily installed along the suction side of the main filter, and the main filter is less likely to be clogged.
It has great practical effects, such as being able to significantly reduce the number of times of cleaning.
