Abstract

A multilayer filtering type facial mask and a using method thereof are provided, comprising a main body having a mask opening disposable on and covering a mouth and a nose and having an installation hole at one side away from the mask opening; and a first filtering member having a casing seat with a filtering material disposed therein. The casing seat is combined with the main body in the installation hole. The casing seat has an air inlet hole at the bottom part outside the main body. An air outlet hole is provided at a top part of the main body. When the main body is worn on the mouth and the nose of a person who inhales, the inhaled air passes from the air inlet hole and moves from bottom to top to pass through the filter material to be filtered thereby and then, discharged from the air outlet hole to the inside of the main body to be inhaled into the body, so as to increase the filtering efficiency.

Description

Multi-layer filtering type facial mask and using method thereof

The present invention relates to a facial mask, and more particularly to a multi-layer filter type facial mask and a method of using the same.

According to the new patent of the Republic of China Patent No. M541315, an "adsorption filter mask" mainly has a body (1) having a mounting hole (11) for a gas permeable module (2) and a filter module ( 3) When installed and positioned with a rope (4) and covered in the nose and mouth, the inhaled air can be filtered to prevent harmful substances from being inhaled into the human body.

However, the filter module (3) is in the direction of the thickness direction of the air permeable module (2), although the filter module (3) has a hot air non-woven layer (31) and an activated carbon module. The multilayer structure of the layer (32), the hydrophilic non-woven fabric layer (33) and the high-efficiency filter material layer (34), but the thickness of the layer is still thin, so that the filtration efficiency achieved when the air passes is insufficient, and if Increasing the thickness of the filter module (3) has the problem of cost increase, which is the focus of the present invention.

The main object of the present invention is to solve the above problems and to provide a multi-layer filter type face mask and a method for using the same, which can increase the path of air filtration by allowing air to pass longitudinally through the filter material, thereby enabling the thickness of the filter material to be increased without increasing the thickness of the filter material. Achieve effective efficiency in filtering.

For the foregoing purposes, the multi-layer filter type facial mask of the present invention comprises:

a body having a cover for covering the nose and mouth, and having a mounting hole on a side away from the cover;

a first filter member is provided with a filter material in the housing, the housing is coupled to the body in the mounting hole, the housing has an air inlet hole at the bottom of the body, and the housing is seated in the body The top has an air vent;

When the body is worn by the mouth and mouth of the person and inhaled, the inhaled air is filtered first through the filter portion, and then filtered by the filter hole from the bottom to the top, and then filtered. The vent is discharged into the body for inhalation.

Wherein the housing is formed by abutting a front cover and a rear cover, the air inlet is disposed at a bottom of the front cover, the air outlet is disposed at a top of the rear cover, and the filter material is wrapped before the docking Cover and the back cover.

Further, a second filter member is disposed on the outside of the body, the second filter member has a filter portion corresponding to the position of the mounting hole, and the second filter member has a body when the body is worn with the cover The positioning part of the fixed position when the mouth and mouth of the person.

Wherein, the first filter member is made of a material having elasticity and gas permeability.

Wherein, the shell has a third filter member that is fixed by the frame and is fixed to the air outlet.

Wherein, the filter material is a material having water absorbability, and can be removed and cleaned by the shell.

Wherein, the filter material is activated carbon filter cotton.

Wherein, the material of the third filter member is a non-woven fabric.

For the purpose of the foregoing, a method of using the multi-layer filter type facial mask of the present invention includes:

The filter material is placed in the housing to form the first filter member, and the housing is placed in the mounting hole and coupled to the body, and the body is positioned after the cover is worn on the mouth and mouth of the person. The air sucked in when inhaling is filtered by the air filter from the bottom to the top through the filter material, and then discharged into the body through the air outlet for inhalation.

Alternatively, the filter material is placed in the front cover, and the filter material is placed in the mounting hole and the body is coupled to the body, and then the second filter member is fixed to the air outlet by the frame. And the back cover is covered by the body and the front cover at the mounting hole to cover the filter material, and the third filter member is covered on the outside of the body, and the filter portion and the mounting hole are disposed. Correspondingly, the body is attached to the mouth and nose of the person with the cover, and the positioning portion is fixed on the head of the human body to position the body, and the air sucked in when inhaling is first filtered through the filter portion. First, the air inlet hole is filtered through the filter material from bottom to top, and then discharged through the second filter member to the body through the second filter member for inhalation.

The above and other objects and advantages of the present invention will be readily understood from

Of course, the invention may be varied on certain components, or in the arrangement of the components, but the selected embodiments are described in detail in the specification and their construction is shown in the drawings.

Please refer to FIG. 1 to FIG. 8 for the embodiments and preferred embodiments of the present invention, which are for illustrative purposes only and are not limited by the embodiments described herein.

The present invention provides a multi-layer filter type face mask comprising a body 1, a first filter member 2, and a second filter member 3, wherein:

As shown in Figures 2 to 3, the body 1 has a cover 11 for covering the nose and mouth, and a mounting hole 12 on a side away from the cover 11; the first filter member 2 is a case The housing 21 is provided with a filter material 22, and the housing 21 is coupled to the body 1 in the mounting hole 12. The housing 21 has an air inlet hole 23 at the bottom of the body 1 and the housing 21 is inside the body 1. The top has an air outlet 24.

As shown in Figures 1 and 6, the body 1 has a positioning portion 13 which can be fixed by the positioning portion 13 when the body 1 is worn at the mouth and mouth of the person. position.

As shown in the second embodiment, the housing 21 of the present embodiment is formed by abutting a front cover 211 and a rear cover 212. The air inlet 23 is disposed at the bottom of the front cover 211, and the air outlet 24 is disposed at the bottom. At the top of the rear cover 212, the filter material 22 is wrapped in the front cover 211 and the rear cover 212 during docking.
