1 and 2, the dust mask according to the present invention includes a main body 10, an eyepiece 20, and first and second hanger strings 61 and 62.

The body 10 is formed in a semi-spherical shape to cover the face of the wearer's mouth and the nose portion. The main body 10 can be formed by stacking sheets of filter media such as gauze and nonwoven fabric having air permeability.

The purification filter unit 11 may be formed in one side of the main body 10 or coupled to the main body 10 to purify the outside air to be introduced into the main body 10.

The eyepiece 20 is joined along the periphery of the body 10 to contact the wearer's face.

And the shape retainer 40 maintains the shape of the main body 10.

The first and second hanger straps 61 and 62 keep the body 10 in close contact with the wearer and keep the dust mask in close contact with the wearer's face. The first and second hanger strings 61 and 62 may be coupled to side surfaces of the main body 10 to have a ring-shaped band structure.

The ring portion 50 is for fixing the first and second hanger strings 61 and 62, respectively, and is formed on both side surfaces of the main body 10.

Referring to Figure 3, the ring portion 50 will be described as follows. The pair of fixing portions 54 formed in the ring portion 50 is fixed by supporting both ends of the first and second hook strings 61 and 62, respectively, so that the hook string has a ring shape.

Each fixing portion 54 includes a fixing portion insertion groove 52 for easily coupling the first and second hanger strings 61 and 62. Fixing portion insertion groove 52 is formed so that the width becomes narrower toward the fixing portion from the outside. The fixing part insertion groove 52 allows the first and second hanger strings 61 and 62 to easily penetrate and be coupled to the fixing part 54, while the first and second coupling parts 52 are coupled to the respective fixing parts 54. 2 Make sure that the hangers (61, 62) do not come off.

In addition, the interval between the fixing portion 54 is formed thinner than the thickness of the first and second hanger string (61, 62). Since the first and second hanger strings 61 and 62 are flexible, including soft rubber, the first and second hanger strings 61 and 62 may be coupled to the fixing part 54 even if the interval between the fixing parts 54 is narrow. Since the thickness of the fixing part 54 is thin as described above, the first and second hook strings 61 and 62 coupled to the fixing part 54 do not easily detach. That is, the anti-vibration mask according to the present invention can be attached and detached to the first and second hanger string (61, 62), while the length can be adjusted, it does not come off easily and does not loosen when worn.

In addition, the pair of fixing parts 54 formed on the first ring part 50 are formed at regular intervals from above and below, respectively. In this case, the interval between the pair of fixing parts 54 may be set so that the interval that the first hanger 61 can pass as if it is caught up and down on one ear of the wearer.

The hook 70 is coupled to the first hanger 61 to engage the first and second hanger 61, 62 at the back of the head of the wearer. The hook 70 includes a hook portion 74 which is formed to hold the second hook string 62 and the gripping groove 72 capable of holding the first hook string 61.

Such a hook 70 will be described in detail with reference to FIGS. 4 and 5 as follows.

The gripping groove 72 of the hook 70 is formed in a hole shape through which the first hook string 61 can penetrate, and at one side of the gripping groove 72, the edge is structurally separated from the guide groove 76. do. In addition, the hook 70 may be formed using a soft resin, plastic, or the like in order to facilitate the fit of the wearer 90 in contact with the back of the head and the grip of the first and second hangers 61 and 62. .

The guide groove 76 is to allow the first hook string 61 to be inserted into the gripping groove 72, the narrower toward the gripping groove 72 from the outside of the hook 70.

In particular, the narrowest width of the guide groove 76 in contact with the gripping groove 72 may be formed thinner than the thickness of the first hanger string (61). As such, although the width of the guide groove 76 is thinner than the thickness of the first hanger 61, the first hanger 61 is connected to the grip groove 72 through the guide groove 76 by the flexibility of the hook 70. Can be combined. That is, since the hook 70 is flexible, the guide groove 76 has a larger gap due to the twist of the hook 70 when the first hook string 61 passes through the guide groove 76, Accordingly, the first hanging string 61 may pass through the guide groove 76.

Of course, although the guide groove 76 is not formed in the gripping groove 72, it is possible to insert the ring-shaped first hook string 61 into the gripping groove 72, but the hook 70 of the dust mask according to the present invention ) Is such that the guide groove 76, the attachment and detachment with the first hanger string 61 is more easy.

The hook portion 74 is formed as a groove having a shape in which a part of the hook 70 is curved inwardly to hook the second hook string 62.

In the dust mask according to the present invention as described above, the wearer 90 pulls the first and second hanger strings 61 and 62 fixed to the pair of ring portions 50 while the wearer wears the dust mask. It can be worn by engaging through the hook (70). In this case, the hook 70 may be coupled to the first hanger 61 through the gripping groove 72 before the wearer 90 wears the dust mask. Accordingly, the wearer 90 may wear the dust mask by simply pulling the first and second hanger strings 61 and 62 to couple the second hanger 62 to the hook 70.

As such, the anti-vibration mask according to the present invention is easier to wear than the anti-vibration mask having only one hangstring that surrounds the back of the head. In addition, it is possible to improve the discomfort of the work in the state wearing the mask by removing the discomfort when the hanger is attached to the ear.

It will be apparent to those skilled in the art that, although several embodiments above have been illustrated by way of example, the present invention may be embodied in many other forms without departing from the spirit and scope of the invention.
