Description

Dust mask

The present invention relates to a dust mask, and more particularly to a so-called 'facial-filtration' dust mask in the form of an edge surrounding and enclosing around the nose and mouth.

In industrial sites, dust, dust, fumes, odors, gases and other harmful elements are distributed in the air. Thus, workers use a dust mask, which is used semi-permanently by replacing only a filter and discarded after one or several uses. The latter is called a 'facial-filtration' dust mask, and the dust mask of the present invention corresponds to this.

1A and 1B show a dust mask 1 disclosed in Korean Patent No. 807505 and a prosthesis 5 inserted therein. The disclosed dust mask 1 includes a mask body portion 2 in a form surrounding a user's nose and mouth, and a ring-shaped eyepiece 3 whose outer periphery is joined to the periphery of the body portion 2, wherein the body On the inner surface of the part 2 is provided a prosthesis 5 of lattice ribs.

This dust mask 1 has the advantage that the face adhesion is good by the eyepiece 3, and the shape of the mask is maintained relatively well by the prosthesis 5. However, as the moisture generated at the time of respiration directly contacts the main body 2, the dustproof filter efficiency is rapidly lowered, and furthermore, the life of the dustproof mask 1 is shortened.

2A and 2B show the anti-vibration mask 6 and the prosthesis 7 inserted therein disclosed in Korean Patent No. 999860 by the applicant. The disclosed dust mask 6 likewise comprises a main body portion 2a and an eyepiece portion 3a, and a thin film-shaped prosthesis 7 is provided on the inner surface of the main body portion 2a. Reference numeral 7a is a protruding guide that protrudes from the surface of the prosthesis 7 so that the inner surface of the main body 2a and the prosthesis 7 do not come into contact with each other.

Due to the characteristics of the prosthesis 7, the dust mask 6 does not come into contact with the body part 2a due to moisture generated by the user's breathing, and thus the problem of the dust mask 1 is solved to some extent. It has the advantage of being.

However, as shown in FIG. 2B, the prosthesis 7 of FIG. 2B has a contact band 8 having a predetermined width W formed on the periphery, and contacts the band 8 of the mask body 2a in correspondence with the band 8. As much as the width (w), the respiratory function and the filter function are lost. The same applies to the prosthesis 5 of FIG. 1B, and also to the dust mask disclosed in Korean Patent No. 133840 although not shown.

As a result, the

dust masks

1 and 6 of the related art have the advantage that the appearance of the

mask body parts

2 and 2a is maintained well by the

prosthetic spheres

5 and 7, There has been a problem that a loss of function by a certain width w and W in which the

main body portions

2 and 2a are interviewed with each other occurs.

The present invention has been proposed to solve the above problem of the conventional dust mask. SUMMARY OF THE INVENTION An object of the present invention is to provide a dustproof mask in which a loss of function of a mask body part does not occur, including a prosthetic tool designed not to be interviewed with the body part.

The anti-vibration mask of the present invention includes a filter main body portion in the form of a face portion space surrounding the nose and the mouth, a ring-shaped eyepiece to which an outer circumference portion is joined to the periphery of the main body portion, and a prosthesis provided detachably to an inner surface of the main body portion. Is done.

In particular, the prosthesis is:

An impervious thin film having intake and exhaust holes;

An outer circumferential end is in contact with the junction between the main body and the eyepiece;

A non-contact flow path connected to the intake hole from the end of the outer periphery by a plurality of radially protruding guides formed on the surface and the outward rounding;

It is characterized by.

Preferably, the outer circumferential portion of the prosthetic sphere is treated in an outwardly round shape for smooth face contact of the anti-vibration mask. In addition, the guide is to be formed inward from the outer peripheral end of the prosthetic sphere. The guides are also linear and have a plurality of regular or irregular gaps in the middle to vary the connection of the flow paths.

Also preferably, the intake hole and the exhaust hole are provided with a check valve for preventing air flow in an unnecessary direction.

According to the anti-vibration mask of the present invention, the prosthetic sphere has only its outer circumference in contact with the joint portion between the mask body portion and the eyepiece portion. In other words, the prosthetic sphere and the main body do not interview each other anywhere. Therefore, in the antivibration mask of this invention, the filter function loss of the mask main body part by an interview does not generate | occur | produce. Therefore, the dustproof efficiency of the dustproof mask is remarkably improved as compared with the conventional one.

Features and effects of the present invention described or not described above will become more apparent through the description of the preferred embodiment of the dust mask according to the present invention described below with reference to the accompanying drawings.

Referring to Fig. 3, a dust mask according to the present invention is indicated by reference numeral 10. The dust mask 10 forms a face portion space covering the nose and the mouth, and is disposed at an appropriate position of the face portion using the fixing bands 14 on both sides. The anti-vibration mask 10 of the present invention includes a filter main body portion 11 forming a face portion space, a ring-shaped eyepiece sheet 12 having an outer circumferential portion joined to a circumferential portion of the main body portion 11, and the main body portion 11. It comprises a prosthesis 20 provided on the inner surface.

Fixing bands 14 are connected to both sides of the main body 11, and the anti-vibration mask 10 of the present invention covers the nose and the mouth with the main body 11 and the eyepiece sheet 12. (14) is wound around the head is fixed in place.

More specifically, the main body 11 may be a PP or PE nonwoven fabric capable of filtering external harmful air as a conventional filter material, and is manufactured to form a hemispherical, rhombic, or other type of face space. Preferably, the main body 11 has a structure in which a plurality of filter materials are stacked.

The eyepiece sheet 12 is a sheet material obtained by laminating a soft resin such as polyurethane on one side of a synthetic fiber fabric such as nylon fiber or polyester fiber, or a soft fabric such as cotton fabric. In another embodiment, a synthetic rubber material such as rubber, silicone, urethane, or the like may be used. However, the sheet material is considered to be advantageous in consideration of facial contact, absorbency, flexibility, and the like.

In particular, the eyepiece sheet 12 is produced in a ring shape of the release considering the shape of the nose, such that it can flexibly respond to the face shape of the user slightly different, and can provide excellent adhesion.

In the present invention, the peripheral portion of the main body portion 11 and the outer peripheral portion of the eyepiece sheet 12 are bonded to each other. As a method of joining, an adhesive, sewing, fusion, etc. can be used, and when the main-body part 11 is a laminated structure, each filter layer is joined simultaneously at this time. The broken line in the figure is the joint 13 formed by inverting the outer and inner parts after the bonding.

Although the structure of the main body 11 and the eyepiece sheet 12 has been described in detail above, these structures are not special in the present invention. However, the anti-vibration mask 10 of the present invention is specially designed and includes a prosthetic tool 20 detachably provided on the inner surface of the main body portion 11.

Referring to FIG. 4, the prosthetic sphere 20 is an impermeable thin film having one intake hole 21 and an exhaust hole 22, and is detachably provided on an inner surface of the main body part 11. On the other hand, the prosthesis 20 includes a plurality of radially protruding guides 23 integrally formed on the surface thereof, and the guide 23 makes no contact between the inner prosthetic sphere 20 and the outer body portion 11. The air passage 24 is formed.

Herein, the prosthetic sphere 20 is sufficient to be an impermeable thin film, and as a material, a plastic resin such as cellulose ester or polyethylene, or a rubber resin such as rubber or silicone may be used. The thickness of the film is preferably 0.3 to 0.6 mm, but the present invention is not limited to the material or thickness of the prosthetic sphere 20.

The guide 23 is shown as a linear but may be composed of a plurality of protrusions, and also in the case of a linear connection of the flow path 24 by placing a plurality of regular or irregular interval grooves 25 in the middle as shown in the drawing. You can also make more variety.

4 and 5, the prosthetic sphere 20 has an outer circumference 28 end thereof in contact with the junction 13 between the main body 11 and the eyepiece sheet 12 on the inner surface of the main body 11. Is mounted. Then, the guide 23, the non-contact flow path 24 is formed on the surface of the prosthetic sphere 20 connected to the intake hole 21 from the end of the outer periphery 28.

Preferably, the outer circumference 28 portion of the prosthetic tool 20 is treated in the form of an outward round R as shown in the figure. This round (R) form is:

First, the round (R) portion is in contact with the face has an effect on the contact feeling and adhesion of the dust mask (10);

Second, without overlapping or interviewing the main body portion 11 and the prosthetic tool 20, there is an advantageous effect that the outer circumference 28 of the prosthetic tool 20 contacts the junction 13.

Without this treatment, the outer periphery 28 causes discomfort by directly pressing the face, while not being in close contact with the face. Furthermore, there is a possibility of slight surface contact between the main body 11 and the prosthetic tool 20 at the outer circumferential portion 28. In this respect, the round R of this embodiment has a significant significance.

In order to eliminate the possibility of surface contact between the prosthetic tool 20 and the main body 11, the end 31 of the guide 23 may be connected to the outer circumference 28 of the prosthetic tool 20. That is, the guide 23 is formed inward from the end of the outer circumference 28 of the prosthetic tool 20. However, as indicated by reference numeral 31a, it will not necessarily be necessary.

On the other hand, the intake hole 21 and the exhaust hole 22 is provided with valve means for preventing the air flow in an unnecessary direction, respectively. The valve means is installed through the prosthesis 20 and covered with an outer main body 11, an intake valve 26 and an exhaust valve installed through the prosthetic tool 20 and the main body 11. And (27). Each

valve

26,27 is a so-called check-valve which enables one-way communication, and thus each is an intake-only and exhaust-only valve.

Each of the

valves

26 and 27 is a

base

28a, 28b fixed to the intake hole 21 and the exhaust hole 22 of the prosthesis 20, and flexible mounted on the

base

28a, 28b. And a check plate 29. Since all the air to be sucked must be filtered, the intake valve 26 is covered with the main body 11, but since the exhaust air does not need to be filtered, the exhaust valve 27 is installed through the main body 11. In the figure, reference numeral 30 denotes an outer cap of the exhaust valve 27.

As described above, the anti-vibration mask 10 of the present invention is fixed in position by winding the band 14 on the head while covering the nose and mouth with the body portion 11 and the eyepiece sheet 12. At this time, by the round (R) of the prosthesis 20, the face contact feeling of the dustproof mask 10 is very soft, the face is also well closed.

The wearer breathes safely through the valve, and the intake valve 26 is opened during inhalation, and the exhaust valve 27 is opened during exhaust. First, when inhaled, the outside air is filtered while passing through the front of the main body 11, which is a filter material, flows along the flow passage 24, and then flows into the respirator of the wearer through the intake valve 26 opened at the suction pressure. do.

Next, during exhaust, the discharged air is blocked by the prosthesis 20 and does not contact the main body 11, but is discharged to the atmosphere through the exhaust valve 27. Therefore, there is no fear that the main body 11 will be wetted by breathing, and of course, there is no fear of damaging the main body 11 due to moisture when breathing.

If the prosthetic sphere 20 has a part interviewed with the main body 11, the respiratory loss and the filter loss by that portion occurs. Therefore, a sufficient degree of air cannot be provided for the user's safe breathing, and the entire area of the main body 11 can not be utilized efficiently.

In the present invention, the outer circumference 28 of the prosthetic tool 20 is designed to contact the junction portion 13 between the main body portion 11 and the eyepiece sheet 12 to eliminate the possibility of mutual interview, at this time The surface of 20 solves these problems by integrally including a plurality of protruding guides 23 which form a non-contact flow path 24 connected from the end of the outer circumference 28 to the intake hole 21. .

Referring to FIG. 6, in the present embodiment, the prosthetic sphere 20 has one central intake hole 21 and one side exhaust hole 22. However, the present invention is not limited to the arrangement and number of intake holes 21 and exhaust holes 22 formed in the prosthetic tool 20.

For example, FIG. 7A illustrates the central intake hole and both side exhaust holes, FIG. 7B illustrates both the intake hole and the center lower exhaust hole, and FIG. 7C illustrates three intake holes and one exhaust hole, respectively, which may be selectively applied to the present invention. .
