Description

Multi-functional dustproof mask

The present invention relates to a multi-use anti-vibration mask, and more particularly, to be worn in a hemispherical shape so that the endothelial is spaced a predetermined distance from the mouth and nose to ensure sufficient filtration space between the wearer's mouth, nose and mask and It prevents direct contact with the wearer's mouth and nose and prevents the mask from getting wet by breathing or snorting from the mouth and nose during exhalation, and evenly breathing air in all parts of the skin when the wearer breathes Or it may be discharged, so the air intake or exhaust resistance can be relatively low, and the air gap between the nose and the cheekbone of the face can be sealed to prevent frost on glasses or protective equipment due to breathing or snorting during breathing discharge. When breathing in, breathe dust, chemicals or scent between your nose and your cheekbones. Which can prevent such inflow, and even a long while wearing the mask can not act comfortably occupy the breath, the present invention relates to an excellent adhesion to the curved face-purpose dust mask.

The mask is mainly used for winter protection in winter, and it is also used to suppress the inhalation of pollen, yellow dust, etc., which occurs mainly in spring, into the human body through breathing, and a lot of dust is generated or paints, chemicals, and chemicals are used. Therefore, in the workplace where odors are generated, dust, chemicals, odors, etc. may be used to suppress inhalation into the human body through breathing. In addition, dustproof masks are also used in production facilities such as semiconductors and LCDs that require cleaning to minimize the generation of particles.

In this regard, a disposable dust mask was proposed in Korean Utility Model Registration Application No. 1990-0003441.

However, such a disposable dust mask is not easy to breathe because the operator's mouth and nose is in direct contact with the mask, the breathing or nostril discharged from the mouth and nose is directly transmitted to the face skin, the user may feel uncomfortable. In addition, due to the close contact with the mask and the mouth and nose, when the mask is worn, the face is not unpleasant to the mask that is moistened by the moisture of the mouth or nose, which is moistened by the moisture of the mouth or nose. You can avoid using it. In addition, due to the direct contact between the face covering the nose and the nose due to the narrow filtration space used for the intake of air is limited to use a high-performance filter attached to the use of a high-performance filter is difficult.

In addition, between the nose and the cheekbones of the human body is not fully adhered to the excitement, which causes frost on glasses or protective equipment due to breathing or snorting during breathing, and between the nose and the cheekbones of the human body when breathing air There is a problem that dust, chemicals, odors, etc. may flow between the gaps.

In addition, a gap is formed between the face and the mask due to the curvature formed on the face between the cheekbone and the jaw, and thus there is a problem in that external dust or the like is not filtered through the gap. Since the adhesion between the mask edge and the face is inferior, there is a limit to using the high-performance filter attached.

The technical problem to be achieved by the present invention is to be worn in a hemispherical shape so that the endothelium is spaced apart from the mouth and nose by a certain distance to ensure sufficient filtration space between the wearer's mouth and nose and mask and the mask and wearer's mouth and nose and It prevents direct contact and prevents the mask from getting wet by breathing or snorting from the mouth and nose during exhalation, and air can be evenly inhaled or expelled from all parts of the skin when the wearer breathes. Inhalation or exhaust resistance of the body can be lowered relatively, and the air gap between the nose and the cheekbone of the face can be sealed to prevent the formation of frost on glasses or protective equipment due to breathing or snoring during breathing. Dust, chemicals, odors, etc. flow between your nose and your cheekbones. It can block, and even a long while wearing the mask can not act comfortably occupy the breath, to provide excellent adhesion to the curved face-purpose dust mask.

The present invention is an inner skin made of a breathable fabric material or a breathable synthetic resin; and an outer skin made of a breathable fabric material or a breathable synthetic resin; and provided between the inner skin and the shell in the longitudinal direction of the mask body, and Has at least one flexible frame made of a material that can be bent by hand and does not break when bent and maintains shape after being bent; and has a shape that can be provided in close contact with the face flexion between the nose and the cheekbones. Fluffy and soft to the touch, made of a material that is elastic, the first protrusion provided to fill the gap between the left cheek of the nose and the face; and the shape that can be provided in close contact with the face flexion between the back of the nose and cheekbones It is made of soft, fluffy and soft and elastic material, and the right cheekbone of the nose and face A second projection provided so as to fill the gap; And it provides a versatile dustproof mask made of a material having elasticity and including a border sealing means for increasing the adhesion of the mask body edge along the curvature of the face.

The multi-use dust mask may be provided with a hook portion on a mask body including an inner skin and an outer shell, and may be provided with a user's desired length by allowing a user to bind a first earring portion and a second earring portion to the hook portion. .

According to the multi-use anti-vibration mask according to the present invention, a sufficient filtration space is formed between the mask body and the wearer's face, thereby facilitating breathing and minimizing the endothelial wet of the mask by the breathing and snoring discharged from the mouth or nose. Not only is it comfortable to wear, but it also ensures a tight seal between the nose and cheekbones to prevent the formation of steam or frost, even when wearing glasses or protective equipment, and when breathing in the air, between the nose and the cheekbones of the human body. It can block the ingress of dust, chemicals and odors.

Due to the hemispherical bending of the flexible frame, the intake or exhaust resistance of the air is relatively high as the endothelium is spaced from the mouth and nose and the air can be inhaled or expelled evenly over the entire part of the skin as the wearer breathes. Will be lowered. The flexible frame can be bent in a hemispherical shape, and the endothelium is inseparable from the flexible frame, preventing the internal endothelium from being sucked into the mouth or nose when breathing air. As described above, the multi-use anti-vibration mask of the present invention has a significantly lower intake or exhaust resistance of air than the conventional mask, and thus can operate much more comfortably without being breathed for a long time while wearing the mask. The shape of the flexible frame has the advantage that the user can be worn to bend freely in the desired shape.

In addition, by forming an edge sealing means with a rubber hose ring having a resilient inside the tubular shape along the edge of the multi-use dust mask is excellent in adhesion to the curved face by the air cushioning action inside the rubber hose ring.
