Description

[Detailed description of the invention] (Industrial application field).

The present invention relates to a small vacuum cleaner that uses a breathable, soft, non-bagged paper such as tissue paper as a prefilter, and particularly relates to a method for attaching the paper.

(Prior art and its problems) Recently, in order to more easily and hygienically perform dust disposal that needs to be done frequently in rechargeable hand vacuum cleaners, etc.
For example, a method has been considered in which a piece of tissue paper is attached to the inner surface of a bag-shaped main filter so that the tissue paper acts as a pre-filter, and after cleaning, the tissue paper is rolled up in a shape that envelops the dust inside and disposed of as is. .

By the way, when putting such a vacuum cleaner into practical use, the method of attaching the tissue paper along the inner surface of the bag-shaped main filter is to attach the tissue paper to the inner surface of the bag-shaped main filter with your fingers, or to use a jig. However, the former method does not allow the tissue paper to fit properly on the inner surface of the bag-shaped main filter and is time-consuming, while the latter method requires the preparation of a separate jig. In any case, it was not very desirable from a practical standpoint.

(Object of the Invention) The present invention has been made in view of the above points, and by applying the paper to the inner surface of the bag-shaped main filter using the suction power of an electric blower, it eliminates the need for a special jig. To provide a paper mounting method that allows paper to be easily and precisely attached to the inner surface of a bag-shaped main filter.

(Method of the Invention) According to the present invention, an electric blower is operated with paper addressed to the opening of the bag-shaped main filter, and after the paper is aligned with the inner surface of the bag-shaped main filter by its suction force, the peripheral edge of the paper is This method achieves the intended purpose.

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

The small vacuum cleaner shown in the figure is a rechargeable, non-rechargeable vacuum cleaner.
Reference numeral 1 indicates a vacuum cleaner main body which forms a dust collection section 2 that opens at the front and has an electric blower 3 and a rechargeable battery 4 such as a lead-acid battery built-in at the rear thereof, 5 indicates a handle of the vacuum cleaner main body 1, and 6 indicates a nozzle. An operation switch 7 provided on the vacuum cleaner body 1 near the vacuum cleaner 5
is a bag-shaped main filter made of cloth, and its mouth is provided with a mouth frame 8 made of an elastic material such as rubber and having a substantially cross-sectional shape,
This opening frame 8 is disposed within the dust collecting section 2 by fitting into the opening of the dust collecting section 2. Reference numeral 9 denotes a lid having a suction port 10, and a cylindrical cover 11 is integrally protruded from the outer periphery of the back side of the lid, and by fitting this cover 11 to the outer periphery of the vacuum cleaner body 1, the opening of the dust collecting part 2 is closed. It is coated to occlude the area. It should be noted that if the lid 9 can be sufficiently maintained by fitting the vacuum cleaner body 1 and the cover 11 together, there is no need to provide a clamping device for locking the lid. Reference numeral 12 denotes a soft, non-bag-like paper having air permeability, such as tissue paper. After this tissue paper 12 is placed on the inner surface, that is, the suction side, of the main filter 7, its peripheral edge is placed on the outside of the vacuum cleaner body 1. It is folded back and clamped between the main body 1 and the lid 9, and the portion 12a exposed to the outside is hidden by the cover 11. Of course,
The cover 11 is made large enough to hide the portion 12a.

In the above configuration, first, the tissue paper 12 is applied to the opening of the dust collecting section 2, that is, the mouth frame 8 of the main filter 7, as shown in the fourth figure, and in this state, the operation switch 6 is turned ON to operate the electric blower 3. Due to the suction force, the tissue paper 12 is suctioned in the direction of the arrow shown in the fourth figure.
It follows the inner surface of the main filter 7 as shown in the figure. After that, the operation is stopped and the cover 9 is attached to the vacuum cleaner main body 1 by sliding it in the direction of the arrow shown in the third figure.
A tissue paper 12 is clamped between the main body 1 and the lid 9, and its outwardly exposed portion 12a is hidden by a cover 11 (see FIG. 1). Therefore, Teishpeno: -1
Even if the portion 12a of No. 2 is not removed, the appearance will not be deteriorated, and when disposing of dust, the tissue paper 12 can easily and reliably envelop the dust inside by utilizing its original size. Furthermore, the tissue paper 14 can be easily applied to the inner surface of the bag-shaped main filter 7 through the suction port of the electric blower 3, eliminating the need to use a special jig.

As described above, when the electric blower 3 is operated with the tissue paper 12 and the main filter 7 installed, the dust-containing suction air flow enters the dust collecting section 2 from the suction port 10 and passes through the tissue paper 12 and the main filter 7. The air passes through the air one after another and is filtered here, and then becomes clean air and is sent to the electric blower 3.
It passes through the fan section of the machine and is discharged outside the machine from the exhaust port.

Thus, the tissue paper 12 collects relatively coarse dust in the suction air flow, and is located before the main filter 7 and acts as a pre-filter.

After cleaning, remove the lid 9, roll up the tissue paper 12 to cover the dust inside, and take out the tissue paper 1''.
I! All you have to do is throw it away, dust can be easily disposed of, and since it uses tissue paper 12, which is readily available and inexpensive in general households, it may be a financial burden to dispose of it every time you clean it. Moreover, by replacing it with a new one every time you clean, you can always exert a high suction force, which 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 7 has a tissue paper 12
The presence of the tissue paper 12 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 12.

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. 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 one 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 structure for fixing the peripheral edge of the paper is not particularly limited, and for example, a structure in which a special fixing frame is used and the paper is sandwiched between the frame and the mouth frame of the vacuum cleaner body or the main filter may be used.

(Effects of the Invention) As described above, according to the present invention, paper can be made into a bag-like main body without using a special jig by utilizing the suction force of an electric blower. It can be applied easily and precisely to the inner surface of the filter, and is excellent in practical use.
