DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a dust mask which can suppress the invasion of fine particles such as pollen or dust in order to prevent allergy caused by sucking the fine particles.

[0002]

2. Description of the Related Art Generally, a commercially available dust-proof mask comprises a mask body having a filter portion and ear hooks. The filter portion of the mask body can prevent intrusion of fine particles. Since there is a certain gap between the edge of the face and the skin on the face, a large amount of fine particles penetrate into the inside of the mask body from such a gap, and there is an inconvenience that the function of the dust mask cannot be sufficiently performed. Was.

For this reason, for example, Japanese Utility Model Application Laid-Open No. 64-26049
As shown in the publication, by providing a face member having elasticity that is turned inward and extends over the entire periphery of the edge of the mask body of the dust-proof mask, the edge of the mask body and the skin A device for eliminating a gap is already known.

Further, as shown in, for example, Japanese Utility Model Application Laid-Open No. 3-75758, an adhesive portion is provided on a peripheral portion of a mask body of a dust-proof mask, and the adhesive portion is adhered to the skin, so that the edge portion of the mask body and the skin are protected. One that attempts to eliminate the gap between the two is already known.

[0005]

However, in the above-mentioned dustproof masks, the face-to-face portion cannot always be perfectly fitted along with the undulation of the face in the above-mentioned dustproof mask.
Eventually, a gap is newly formed between the face-facing member and the skin, and there is a problem that fine particles such as pollen and dust may enter the inside of the mask body from the gap.

Further, among the above-mentioned dust-proof masks, the later-described ones cannot always completely adhere the adhesive portion along the undulations of the face over the entire circumference. There is a disadvantage that fine particles such as pollen and dust may enter the inside of the mask main body through the gap.

Therefore, in the present application, in view of the above-mentioned problems, in accordance with the undulation of the face, the face is fitted more closely than the conventional dust-proof mask, or the gap between the edge of the mask body of the dust-proof mask and the skin on the face. The present invention provides a dust mask that can prevent pollen, dust, and other fine particles from entering from the gap between the edge of the mask body of the dust mask and the skin of the face by removing even if fine particles, such as pollen and dust, enter the surface. The purpose is to do.

The mask body 3 has a substantially bowl shape along the undulation of the face so as to fit the skin 4 on the face.

The edge of the mask body 3 is provided with a first electrostatic seal member (a first electrostatic seal member to distinguish it from the other embodiments).
It is called an electrostatic seal member. 5 ) are provided. The first electrostatic seal member 5 is provided with a cord 10 as shown in FIG.
Is connected to a high-voltage power supply 15 described below, and is in contact with a flat insulator 6 made of, for example, foamed rubber, and the back surface of the insulator 6, and is directly connected to the cord 10. An electrode 7 made of a flat aluminum tape,
A high resistance member 8 made of semi-cylindrical cotton that encloses the electrode 7
And a thin film 9 that covers the side surface of the high resistance member 8. Note that 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 providing an electrostatic action to 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 supply 15 of about 15 KV and a first high voltage power supply 15. Discharge part 20 comprising the electrostatic seal member 5 of FIG. 1 and the needle electrode 21 and the plate electrode 22 interposed therebetween.
And are wire-coupled with a cord 10. The high-voltage power supply 15 is small enough to be stored in a clothes pocket or the like.

The needle electrode 2 of the discharge section 20
1 is connected to the high voltage output side of the high voltage electrode 15 via the cord 10a, and the flat electrode 22 is connected to the needle electrode 2
1 and about 6 mm, and is connected to the electrode 7 of the first electrostatic seal member 5 via the cord 10b.

The first electrostatic sealing member 5 is electrically connected to a cord 10c in which the film 9 contacts the skin 4 of the face and is connected to the ground side of the high-voltage power supply 15 through the skin 4 of the face. doing.

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

Next, electric discharge is performed from the needle electrode 21 to the plate electrode 22, and the negative charge of the plate electrode 22 moves to the needle electrode 21, and the first electrostatic charge is transferred from the plate electrode 22 via the cord 10b. The portion up to the seal member 5 will have a positive charge.

However, no discharge is performed between the first electrostatic seal member 5 and the skin 4 of the face, so that the skin 4 of the face remains negatively charged. Therefore,
An electric field is generated by a potential difference between the film 9 and the skin 4 of the face, so that a so-called Coulomb force acts. Therefore, the film 9 can be brought into close contact with the skin 4 of the face, and fine particles enter from the edge of the mask body 3. Can be eliminated.

In the above description, the case where the first seal member 5 is provided at the edge of the mask main body 3 of the dustproof mask 1 has been described. However, the present invention is not necessarily limited to this, and is shown in FIGS. 4 and 5. Second seal member (first seal member
5 to be referred to as a second seal member. ) 30 may be used.

As shown in FIG. 4, the second seal member 30 is connected to a high-voltage power supply 15 described below via a cord 10, and is connected to a flat insulator 6 made of, for example, foamed rubber. Abutting against the back surface of the insulator 6, the cord 1
It has an electrode 7 made of a flat aluminum tape directly connected to the electrode 0 and a high-resistance member 31 surrounding the electrode 7. A brush 32 made of, for example, nylon is attached to the lower surface of the high resistance member 31 at a high density.

A high voltage application circuit 35 for providing an electrostatic action to the second electrostatic seal member 30 will be described with reference to FIG. However, the configuration of the high voltage power supply 15 and the discharging unit 20 is as follows.
The description is omitted because it is the same as the high voltage application circuit 11.

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

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

Next, a discharge is performed from the needle electrode 21 to the flat electrode 22, and the negative charge of the flat electrode 22 moves to the needle electrode 21, and the second electrostatic charge is transferred from the flat electrode 22 via the cord 10 b. The portion up to the seal member 30 will have a positive charge.

However, since no discharge is performed between the second electrostatic seal member 30 and the facial skin 4, the facial skin 4 remains charged. Therefore, due to the potential difference between the brush 32 and the skin 4 on the face, the tip portion of the brush 32 becomes an unequal electric field and a so-called gradient force acts, so that a dust collecting action can be provided. Particles that have invaded
Can collect dust.

Finally, the two previously described embodiments are shown in FIG.
However, the present invention is not limited to being provided at the edge of the dust mask 1 shown in FIG. That is, as shown in FIG. 6, the eyes and the nose can be covered with the mask main body 3 and the dustproof mask 1 can be used as a type having a filter section 2 using a fine mesh or the like on the upper part of the mask main body 3.

[0029]

As described above, according to the first aspect of the present invention, the film constituting the first electrostatic sealing member provided on the edge of the mask body is electrostatically applied to the skin on the face. The close contact can prevent such fine particles such as dust from entering the inside of the mask body.

According to the second aspect of the present invention, the brush forming the second electrostatic seal member provided at the edge of the mask body by the electrostatic action is formed by the brush and the face of the mask body. By collecting fine particles such as pollen and dust that have entered the gap with the skin, it is possible to suppress such fine particles from entering the inside of the mask body.

By interposing a discharge portion between the high-voltage power supply and the electrode of the first or second electrostatic seal member, the voltage supplied to the first or second electrostatic seal member is reduced.
Since the current can be limited, it is possible to prevent electric shock even if the electrode is directly touched.
