2. Description of the Related Art Generally, a commercially available dust-proof mask is composed of a mask body having a filter portion and an ear hook, and it is possible to prevent fine particles from entering the filter portion of the mask body. Since there is a certain amount of clearance between the edge of the mask and the skin on the face, a large amount of fine particles penetrate into the inside of the mask body from such clearance, and the dust mask function cannot be fully achieved. Was.

Therefore, for example, Japanese Utility Model Laid-Open No. 64-26049
As shown in the publication, by providing an elastic face-contact member that cuts back and extends inward over the entire circumference of the edge of the mask body of the dust-proof mask, the edge of the mask body and the skin It is already known to try to eliminate the gap.

Further, as disclosed in, for example, Japanese Utility Model Laid-Open No. 3-75758, an adhesive portion is provided on the peripheral portion of the mask body of the dustproof mask, and the adhesive portion adheres to the skin, so that the edge portion of the mask body and the skin It is already known to try to eliminate the gap between and.

[0005]

However, among the above-mentioned dust masks, the above-mentioned dust masks do not always fit the face-contact portion in accordance with the undulations of the face.
Eventually, a gap is newly formed between the face-contacting member and the skin, and there is a disadvantage that fine particles such as pollen and dust may enter the inside of the mask main body through the gap.

Further, among the above-mentioned dust masks, the one described later does not always allow the adhesive part to be completely adhered along the undulations of the face over the entire circumference, so that the adhesive part in the non-adhesive part and the skin of the face are not adhered. There is a problem that fine particles such as pollen and dust may enter the inside of the mask body through the gap.

In view of the above-mentioned problems, the present application provides a more fit than a conventional dust mask in accordance with the undulation of the face, or a gap between the edge of the mask body of the dust mask and the skin of the face. Provides a dust mask that can prevent fine particles such as pollen and dust from entering through the gap between the edge of the mask body of the dust mask and the skin of the face by removing even fine particles such as pollen and dust The purpose is to do.

[0008]

SUMMARY OF THE INVENTION The main point of the dust mask according to claim 1 is that it is provided over the entire circumference of the mask body having a filter portion and the edge portion of the mask body. A first electrostatic seal member having a high resistance member in the center, a film on the skin side of the face, and an electrode on the skin side of the other face, and a high voltage output of a high voltage power source on the electrode of the first electrostatic seal member. And a high voltage applying circuit for applying the ground side of the high voltage power source to the skin side and the skin side.

Further, the gist of the dust mask according to the present invention is to provide a mask main body having a filter portion and a high resistance member provided at the entire periphery of an edge portion of the mask main body.

Therefore, according to the first aspect of the present invention, the film constituting the first electrostatic sealing member provided on the edge portion of the mask main body is brought into close contact with the skin of the face by the electrostatic action. Therefore, the gap between the mask body and the skin on the face can be further eliminated.

According to the second aspect of the present invention, the brush forming the second electrostatic sealing member provided on the edge of the mask body is electrostatically acted so that the brush and the face of the mask body face. Since fine particles such as pollen and dust that have entered the gap between the skin and the skin can be collected, a small gap between the mask body and the skin on the face can be allowed.

Embodiments of the present invention will be described below with reference to the drawings.

1 to 3 show an embodiment of a dustproof mask 1 according to the present invention. The dustproof mask 1 is provided with a mask main body 3 provided with a filter portion 2 using, for example, a fine mesh. The mask body 3 has a substantially bowl shape along the undulations of the face so as to fit the skin 4 on the face.

A first electrostatic seal member 5 is provided at the edge of the mask body 3. As shown in FIG. 2, the first electrostatic seal member 5 is connected to a high-voltage power source 15 described below via a cord 10, and includes, for example, a flat plate-shaped insulator 6 made of foam rubber or the like, A high resistance member 8 made of a flat aluminum tape that is in contact with the back surface of the insulator 6 and is directly connected to the cord 10 and a semi-cylindrical cotton that wraps the electrode 7. And a thin film 9 which covers the side surface of the high resistance member 8. The film 9 also has a role of enhancing the feeling of contact with the skin 4 on the face.

A high voltage applying circuit 11 for producing an electrostatic action on the first electrostatic seal member 5 will be described with reference to FIG. 3. The high voltage applying circuit 11 includes a high voltage power source 15 of about 15 KV and a first high voltage power source 15. Of the electrostatic seal member 5 and the discharge portion 20 including the needle electrode 21 and the flat plate electrode 22 interposed therebetween.
And are wired and connected by a cord 10. The high-voltage power supply 15 is a small product that can be stored in a pocket of clothes or the like.

The needle-shaped electrode 2 of the discharge part 20
1 is connected to the high voltage output side of the high voltage electrode 15 via the cord 10a, and the plate electrode 22 is the needle electrode 2
1 and about 6 mm apart from each other, and is connected to the electrode 7 of the first electrostatic seal member 5 via the cord 10b.

Further, the first electrostatic seal member 5 is electrically connected to the cord 10c in which the film 9 contacts the skin 4 on the face and is connected to the ground side of the high-voltage power supply 15 via the skin 4 on the face. is doing.

However, according to the above configuration, when the voltage is applied, the needle electrode 21 is positively charged, and
The plate electrode 22 has a negative charge. Further, the first electrostatic seal member 5 is positively charged, and the skin 4 on the face is negatively charged.

Next, the needle-shaped electrode 21 is discharged to the flat plate electrode 22, the negative charge of the flat plate electrode 22 moves to the needle-shaped electrode 21, and the first electrostatic charge is discharged from the flat plate electrode 22 through the cord 10b. The part up to the seal member 5 is charged with a positive charge.

The second seal member 30 is connected to a high voltage power source 15 described below via a cord 10 as shown in FIG. 4, and is made of, for example, a flat plate-like insulator 6 made of foam rubber or the like. , Contacting the back surface of the insulator 6,
It has an electrode 7 made of a flat aluminum tape directly connected to 0, and a high resistance member 31 surrounding the electrode 7. Then, a brush 32 made of nylon, for example, is attached to the lower surface of the high resistance member 31 at a high density.

A high voltage applying circuit 35 for exerting an electrostatic action on the second electrostatic seal member 30 will be described with reference to FIG. However, the configurations of the high-voltage power supply 15 and the discharge unit 20 are
Since it is the same as the high voltage applying circuit 11, its description is omitted.

In the second electrostatic seal member 30, the electrode 7 is connected to the plate electrode 22 of the discharge section 20 via the cord 10b, and the brush 32 is in contact with the skin 4 on the face (but not necessarily in contact with the skin 4). ), And the skin 4 on the face is connected to the ground side of the high-voltage power supply 15 via the cord 10c.

However, according to the above construction, when a voltage is applied, the needle electrode 21 is positively charged, and
The plate electrode 22 has a negative charge. In addition, the second electrostatic seal member 30 is positively charged, and the skin 4 on the face is negatively charged.

Next, the needle electrode 21 is discharged to the flat plate electrode 22, the negative charge of the flat plate electrode 22 moves to the needle electrode 21, and the second electrostatic charge is discharged from the flat plate electrode 22 through the cord 10b. The part up to the seal member 30 will be charged with a positive charge.

However, since electric discharge is not performed between the second electrostatic seal member 30 and the skin 4 on the face, the skin 4 on the face remains negatively charged. Therefore, due to the potential difference between the brush 32 and the skin 4 on the face, a non-uniform electric field is generated at the tip of the brush 32, and a so-called grading force is exerted. The fine particles that have entered from the
