Description

Filter for Mask {filter of Mask}

The present invention relates to a filter for a mask, and more particularly, to a filter for a mask that filters fine dust when breathing by a mask user.

In general, masks are used to prevent damage to others due to airborne fine dust or virus fine dust entering the human body through the respiratory tract or air leakage such as a cold virus.

Meanwhile, in recent years, the necessity of using a mask throughout the four seasons is increasing due to pollutants such as yellow dust or soot and SARS virus, and various types of masks have been proposed.

As an example of such a mask, Patent Registration No. 10-1730083 has been proposed. This relates to a mask provided with an exhaust valve, and includes a mask-shaped body, an opening formed in the body, and formed to penetrate into a position corresponding to the user's mouth, and an exhaust valve formed in the opening, wherein the exhaust valve has an opening. Accordingly, it is coupled to the upper side of the outer frame to prevent breathing inside the mask body while blocking external dust flowing into the outer frame and the opening formed at the same time when the body is formed, and moves to close the intake opening, and when exhausting A mask structure provided with an exhaust valve including a suction film that moves to open a mask is proposed.

However, the exhaust valve proposed in the registered patent is installed in a position corresponding to the user's mouth, that is, in an opening formed in the center of the body, and has a structure in which a thin, simple suction film such as rubber or silicone is provided on the outer frame. When exhaling, air can be expelled quickly, but when inhaled, air flows only through the mask body surface, so the efficiency of filtering fine dust of the air flowing through the mask body is low. As the fiber must be filtered and introduced into the respiratory tract, if the fibrous tissue constituting the mask body is dense, the elderly and the elderly with low lung capacity may feel frustrated, which causes the burden of wearing the mask.

In particular, since the exhaust valve is provided in addition to the suction membrane that opens and closes the opening, when the mask user speaks loudly or sneezes, saliva such as saliva is directly bent and discharged to the front of the mask through the open opening. As a result, there is a high possibility of discomfort to the other party in the conversation, and there is a high possibility that a cold virus etc. may leak when the mask user exhales because there is no air filtering performance.

Accordingly, the present invention has been conceived to solve the fundamental problems of the prior art, and an object of the present invention is to provide a filter for a mask that effectively filters fine dust in the air when a mask user inhales.

The present invention in order to solve such a technical problem;

According to FIGS. 1 to 7, the mask 1 provided with a filter for a mask according to the present invention filters fine dust through a breathing assembly when external air is introduced when the user inhales, as well as quickly discharges air when exhaling. Let this happen.

The mask 1 includes a mask body 100 that covers the nose and mouth of the user's face and face, a fixing part 200 that is hung on the user's ears or wrapped around the back of the head at both ends of the mask body 100, and the It is mounted on the mask body 100 and includes a breathing assembly 300 that quickly discharges air when the user exhales and filters fine dust in the air when inhaling.

Hereinafter, the configuration of each part of the mask will be described in detail.

The mask body 100 has a front cover 110 surrounding the front of the respirator including the nose and mouth, and one end is integrally fixed to the upper and lower edges of the front cover 110, and the other end is in close contact with the user's face. It consists of upper and lower support members 120.

At this time, the front cover 110 is preferably made of a non-woven fabric made of PP or PE material so that the center portion can be flexibly folded, but if necessary, the center is a material such as polyethylene (PE) or polypropylene (PP) that is harmless to the human body. It is a structure that can wrap the respiratory tract by bending on both sides, and injection molding with synthetic resin material so that the surface is smooth, or by thermocompressing a film to form a smooth surface.

In addition, the upper and lower support members 120 are flexible and can be combined integrally by heat-sealing the upper and lower edges of the front cover 110, which is also made of a nonwoven fabric made of PP or PE material.

This is the first direction control plate 370, the rotation shaft (370a) rotates around the shaft hole (312c), and the first direction control hole (370c) formed on the surface of the first direction control plate (370) is the first direction hole (312b) ) While opening and closing the fragrance discharge amount of the first fragrance 330, and the second direction control plate 372 slides up and down along the guide hole 315c into which the slide protrusion 372a is inserted, and the second direction control plate 372 While opening and closing the second direction hole 315b, the amount of fragrance discharged from the second fragrance 332 is adjusted.

After the scent emission control of the first and second fragrances 330 and 332 is finished, if the mask user wears and uses the mask 1, the scent of the first and second fragrances 330 and 332 is refreshed when inhaling or exhaling. I can feel it.

Once the mask user exhales, the first and second opening/closing pads 340 and 342 are tilted forward, opening the first and third ventilation holes 313b and 317b to allow air to pass through the first and third seating chambers 313 and 317. It is discharged forward. Thereafter, when breathing is stopped or inhaled, the first and second opening and closing pads 340 and 342 are returned to close the first and third ventilation holes 313b and 317b.

In this case, when exhaling through the nose, the air is guided to the third ventilation hole 317b by the exhalation guide member 380 so that the air is quickly and smoothly guided in the direction of the third ventilation hole 317b.

In addition, when inhaling, various kinds of dust are filtered through sequentially through the front filter 354 and the rear filter 352, which are air filtering means 350 seated in the second seating chamber 314.

Meanwhile, FIG. 9 is a view illustrating another embodiment of a rear filter according to the present invention.

This relates to a pillar-shaped filter (352a) constituting the rear filter 352, and to manufacture it, the dried pine needles are pressed with a hot press at 100 to 150°C to have a thickness of 0.1 to 0.5 mm. A pine needle thin plate roll 3251 in a state in which (3521a) is wound on a roll, a non-woven fabric roll 3252 in a state in which a nonwoven fabric 3522a is wound on a roll, and bamboo on the central axis so as to have a thickness of 0.1mm to 0.5mm. After preparing a bamboo thin plate roll 3523 in a state in which a bamboo thin plate 3523a, which is produced by turning it in a direction perpendicular to the surface of the roll, is wound on a roll, the pillar-shaped filter 352a includes a pine needle thin plate 3251a and a nonwoven fabric. (3522a) and bamboo thin plate (3523a) are sequentially stacked and rolled into a roll shape to manufacture.

At this time, the thin pine needles 3251a are manufactured from dried pine needles, and the thin pine needles 3251a are continuously formed and supplied from the pine needles thin roll 3251 in a state wound on a roll and used.

The pine needles used in the manufacture of such thin pine needles (3521a) contain vitamins A, C, and K, helping blood circulation, helping skin beauty, relieving fatigue, improving immunity, and preventing gastrointestinal diseases. Silver not only makes you feel refreshed, but also has a terpene, a type of phytoncide, which expands the peripheral nerves and increases the secretion of hormones to wake up the body's tissues.

In particular, pine needles are immersed in purified water for 1 to 2 days to remove a certain part of pine needles, then dried so that the moisture content is about 10 to 15%, and pressurized with a hot press of 100 to 150℃ to secure pores of 0.1 to 0.5mm. To manufacture a thin pine needle plate (3521a) having a thickness. This thin pine needle plate 3251a is continuously formed and wound on a roll. In this case, it is also possible to wind up the thin pine needle plate 3251a in close contact with one side of the release paper.

Next, the non-woven fabric 3522a is for preventing distraction of the pine needles thin plate 3251a and filtering dust particles at the same time, and may be made of various materials such as natural fibers or synthetic fibers, and the thickness is 0.1 to 1 mm. It is preferable to use one having a thickness. This non-woven fabric (3522a) is also continuously formed and is used by being supplied from the non-woven fabric roll (3522) wound on the roll.

In addition, the bamboo used in the manufacture of the bamboo thin plate 3523a is cold in nature, has a sweet taste, and is not poisonous, so it has the effect of removing sputum and removing heat, and also serves to lower the temperature of the air.

At this time, after drying the bamboo to a moisture content of 10% or less, the bamboo is rotated in a direction orthogonal to the central axis to have a thickness of 0.5mm to 0.5mm, and the surface is turned on by a cutter to manufacture a bamboo thin plate 3523a. The bamboo thin plate 3523a is continuously molded and wound on a roll. In this case, it is possible to wind the bamboo thin plate 3523a in close contact with one side of the release paper.

The pine needles thin plate 3522a and the bamboo thin plate 3523a have fine pores to allow air to pass through, and as fine dust in the air is adsorbed to the fibers during the passage of the air, the fine dust filtering function is also performed.

In a state in which the prepared pine needle thin plate roll 3251, the non-woven fabric roll 3522 and the bamboo thin plate roll 3523 are stacked in order, roll them into a roll shape and wind them to have a diameter of 6 to 9 mm to form a cylindrical shape, and a length of 3 to 10 mm It is cut to complete the column-shaped filter (352a).
