2. Description of the Related Art

[Problems to be solved by the invention]

 Conventionally, dust masks and gas masks have been provided with a mask body that covers the entire face, and a dust can and a gas can attached to the mask body via a connecting hose. Therefore, its capacity and weight were large. Therefore, since the mask body covers the entire face, especially in the summer, the worker is hot and exhausts physical strength, and lacks workability and convenience. In addition, since the mask itself is large and heavy, the operator often hassle in wearing the mask, and there has been a problem that the ease of use has been lacking. In addition, dust masks have a habit of closing their mouths, especially in places where there is a lot of dust, so there is no need to wear a mouth mask that covers the mouth, leading to poor handling properties and an increase in weight.

[0003] In view of the above problems, the present invention has a light weight, a small shape, a simple structure, and is dustproof provided with handleability, light weight, and ease of use. The purpose is to provide a mask.

[0004]

[Means for Solving the Problems]

 In order to solve the above problems, the present invention provides a dust mask including a mask body formed so as to cover a partial shape of a nose, an intake / exhaust section formed in the mask body, and a mask body provided in the mask body. The hose is characterized in that it has a hose connected at one end and connected to the dust collection case at the other end.

[0005] Furthermore, the suction / exhaust portion of the mask main body may be provided so as to protrude outside the mask main body, or may be mounted inside the mask main body. Further, even if the suction / exhaust portion of the mask main body is provided at an appropriate position separated from the mask main body, the same effect as the dust collecting action can be obtained.

Further, the dust collecting case is characterized in that an adsorbent such as activated carbon is stored therein, and the adsorbent is detachably provided in the dust collecting case to constantly maintain the adsorbing action. It is possible.

[Embodiment of the invention]

 Hereinafter, embodiments of the present invention will be described with reference to the drawings. FIG. 1 is an exploded perspective view of the dust mask according to the present invention. Reference numeral 1 denotes a dust collecting mask. The dust collecting mask 1 includes a mask body 2, a hose 3, and a dust collecting case 4. The mask body 2 has a cylindrical shape formed so as to cover the nasal cavity and the nose column of a person, and is not a large shape that covers a person's face as in the related art. The size is so small that it does not hinder the installation, and the simplicity and weight reduction when mounting is achieved. As shown in the figure, the mask body 2 shown in FIG. 1 is provided with a suction / exhaust section 5 protruding from the tip thereof, and the suction / exhaust section 5 is opened and closed by the main body 6 connected to the mask body 2 and the main body 6. As shown in a longitudinal side view of FIG. 2, an intake / exhaust valve 9 made of a soft rubber or a soft synthetic resin material is disposed on a top surface of a main body 6 via a support shaft 8 as shown in a vertical sectional side view of FIG. Has been established. Due to the softness of the intake / exhaust valve 9, the valve itself opens and closes in response to the worker's breathing, and absorbs and exhausts air (see FIG. 2). The intake / exhaust valve 9 may be formed as a filter material for removing particulate matter such as paint powder or a filter valve for adsorbing these. Reference numeral 10 denotes a plurality of suction / exhaust holes formed in the outer peripheral portion of the lid 7, reference numeral 11 denotes a connection port with the hose 3 protruding from the side surface of the mask body 2. A connection port 11 with the hose 4 is provided protruding. Further, in the present embodiment, the suction / exhaust portion 5 is provided so as to protrude from the main body 6, but may be provided inside the front end portion of the mask main body 2. In the figure, reference numeral 12 denotes a belt worn on the face.

The hose 3 is formed in a bellows shape, and can be expanded and contracted to a desired length. The dust collecting case 4 that absorbs fine particles such as paint powder stores the adsorbent 13 filled with activated carbon in a case base 14 and screws the upper case 15 from above. Be composed. In the illustrated example, the adsorbent 13 is housed in a porous case, but is not limited to such an embodiment. It may be composed of a filter material such as filter paper, wool felt, non-woven fabric treated with special resin, glass fiber, etc., and an absorbent that adsorbs, neutralizes, or detoxifies harmful gases, etc. Only the absorbent may be stored in the dust collecting case 4. When the adsorbent 13 loses its adsorbing action, the dust collecting case 4 itself can be discarded and replaced with a new dust collecting case 4 filled with a new adsorbent 13. However, only the adsorbent 13 is used. The case may be detachable so that only the new adsorbent is replaced. An intake / exhaust valve 16 communicating with the hose 3 and communicating with the adsorbent 13 is provided on the case base 14 in the same manner as the mask body 2, and the material is the same as that described above. It is the same as in the case of the mask body 2 that may be configured as a filter valve provided. In the drawing, reference numeral 17 denotes a suction / exhaust hole formed in the upper cover 14. In this case, since the dust collecting case 4 is often placed in the pocket of the work clothes in the use state described later, the provision of a large number of the suction and exhaust holes 17 does not hinder the operation of the suction and exhaust.

When using the dust collecting mask 1 configured as described above, as shown in FIG. 4, the mask main body 2 is applied only to the nose portion and the worker M 1 Wear it on your face. At this time, since the mask main body 2 covers only the nasal cavity and the nose column, the mounting operation is simple and short, and the weight is light, so that the handling is excellent. As shown in FIG. 4, when the paint is sprayed on the decorative plate 18, paint powder, dust, and other particulate matter scattered by the spray gun 19 through the suction and exhaust holes 10 of the mask body 2 are removed by the suction and exhaust valve 9. And is adsorbed from the hose 3 by the adsorbent 13 made of activated carbon in the dust collecting case 4. Therefore, the dust collecting operation can be easily performed without imposing a great burden on the worker M. At this time, when the intake / exhaust valve 9 of the mask body 2 is provided with a filter function (filter material or the like), harmful dust and toxic gas can be eliminated. Similarly, if the dust collecting case 4 contains a filtering function (eg, a filtering material) and an absorbent, paint powder, dust, and other toxic gases can be filtered and absorbed, which is extremely useful.

FIG. 5 is a perspective view showing another embodiment of the dust collecting mask 2 according to the present invention. In this embodiment, the intake / exhaust section 5 having the intake / exhaust valve 9 is attached to the vicinity of the dust collecting case 4 via the connection port 11. In this case, the particulate matter can be absorbed by the intake / exhaust section 5 near the dust collecting case 4 without providing the intake / exhaust valve in the mask body 2. Other configurations are the same as those of the above-described embodiment, and a detailed description thereof will be omitted.

FIGS. 6 and 7 are perspective views showing another embodiment of the present invention. In order to prevent toxic gas and the like, a long-elliptical mouth mask 21 is formed along the shape of the mouth, and a connecting hose 22 is attached to the mouth mask 21 to the connecting port 11 of the mask body 2. The hose 3 can be connected to the hose 3. As shown in FIG. 7, in the present embodiment, since the mask also covers the mouth, there is an effect that the inhalation of fine particle powder and toxic gas can be effectively prevented. In addition, since the mouth mask 21 is formed according to the shape of the mouth, the advantages of simplicity of use, handling, and lightness are not impaired. In the figure, reference numeral 23 denotes a mouth belt.

[Effect of the invention]

 As described above, according to the present invention, the structure is simple, the handleability and the lightness are excellent, and the complicated mounting that is common in this type of mask is eliminated, and the use is extremely easy and simple. There is an advantage that it is possible to provide a dust-collecting mask that is excellent in both performance and portability.
