Description

Detachable mask with improved mask replacement and ease of use {The High efficiency horizontal filter device applied to dust collection system for garlic}

The present invention relates to a mask having mask replacement and convenience, and more particularly, it is configured so that only the mask parts that are likely to be contaminated by direct contact between the nose and mouth can be easily replaced in a detachable form to improve the sanitary environment The main purpose of the present invention is to provide a detachable mask with increased ease of replacement and ease of use, which can prevent ear pain due to long-time use by adjusting the length of the strap worn on the ear.

Currently used masks are used to prevent viruses in the air and droplets discharged by virus carriers from being inhaled through the respiratory tract as a respiratory tract of the human body, as well as to reduce the discharge of droplets and viruses from the wearer.

Such a mask is manufactured through a separate fusion bonding process to a mask manufactured through a filter mixture layer in standards such as KF94, KF80, KF-AD, etc., and a usable mask is manufactured.

However, there is a problem that the wearer cannot properly replace or easily replace a mask that meets the standard according to the wearer's usage environment, so he or she must carry an extra mask or replace another mask.

In addition, the current mask has a separate strapping process added to the filter mask manufactured according to the standards such as KF94, KF80, KF-AD, etc., and additional process equipment and manpower for defect inspection are added, increasing production time and cost. There is a problem of low price competitiveness.

In this way, the current mask manufacturing product must necessarily connect the strap and the mask for use, so a work process is added and various products cannot be produced accordingly. A method for improvement is required, and various types of prior art are known to solve these problems.

For example, in Korean Patent Registration No. 10-1140281 (published date: 2011.01.24.), “In a nose and mouth separate mask that filters air introduced by the user's breathing, it is introduced into the user's nose by inhalation breathing. A nose mask that filters the air that is inhaled and filters the air introduced into the user's mouth by breathing, and a mouth mask that is detachable from the nose mask and a fastening hole opened in the nose mask and a fastening passage opened in the mouth mask and a strap connecting the nose mask and the mouth mask, and the nose mask is formed to cover a plurality of ventilation holes formed to communicate with the user's inscription and the outside of the nose mask, It includes a one-way discharge diaphragm for discharging internal air and blocking the inflow of air outside the nose mask, wherein the ventilation hole and the one-way discharge diaphragm are inclined to face the user's inscription, and the nose and mouth are separated. There is a mask.”

In addition, Korean Utility Model Registration No. 20-0204643 (published date: 2000.12.01.) “In a filter replacement mask composed of a case, tube, filter, etc., between the mask case (1) and the filter (3) In addition, in order to eliminate the gap between the mask case (1) and the face to prevent contaminated air from directly entering the mask, the mask case (1) is a thin plastic with excellent flexibility and adheres to the face, and has four connecting rings ( 5a, 5b, 5c, 5d), filter holding protrusion 6 and filter guide protrusion 7 are formed. There, the air tube (2) is made of vinyl or rubber material and is filled with air inside, and a bag cover film (9) is attached to the outside thereof, and the connecting ring holes (10a, 10b, 10c, 10d) are The filter 3 has an ejector installation hole 11 formed in the center and a hooking end 12 is formed at the end. The outer side of the filter 3 is thicker than the inside, ) is composed of a socket 13, a cover 14, and a blocking film 15 that can be separated and combined, so that the mask case 1, the air bag 2, the filter 3, and the air exhauster 4 can be integrated. After inserting the connection rings (5a, 5b, 5c, 5d) of the mask case (1) into the connection ring holes (10a, 10b, 10c, 10d) of the air bag (2), insert the bag cover (9) into the mask case ( 1) is covered on the outside, and the bag cover film (9) and the mask case (1) are fused or bonded, and the filter (3) with the air exhauster (4) installed in the exhauster installation hole (11) is inserted into the mask case (1) A filter replacement mask equipped with a face assembly, characterized in that it is inserted from the outside to the inside and used by connecting the bands (16a, 16b, 16c, 16d) to the connecting rings (5a, 5b, 5c, 5d).” there is,

In addition, Domestic Registered Utility Model Publication No. 20-0479660 (published date: 2016.01.11.) “A body 11 made of a fabric having elasticity and covering the wearer's nose and mouth and both sides of the body 11, respectively. The mask 10 is formed and equipped with a strap 12 to hang on the wearer's ears, and is attached and detached by the inner surface of the main body 11 and the fixing means 33 of the mask 10, filtering fine dust and simultaneously filtering fine dust from the inner surface. It consists of a filter 20 that prevents contact with the mask contaminated by contacting the wearer's mouth and nose, but the fixing means 33 has one end fixed at an appropriate interval on the upper and lower parts of the inner rim of the main body 11, , The other end is cut so that the upper and lower portions of the engaging sheet 33a protrude in the center direction at the upper and lower portions, and the upper or lower portion is cut to become the hinge portion 33b in the center of the engaging sheet 33a to have its own elasticity and have a width of 3mm to 5mm A hooking part 33c and a cutout 33d are formed so that the hooking part 33c can be inserted into the filter 20 corresponding to the hooking part 33c, and the filter 20 is formed on the outer surface. A filter cloth 21 filtering fine dust by forming natural or synthetic fibers into a non-woven fabric while being disposed; A filter paper 22 that is disposed on the inner surface and formed of soft polyethylene to directly contact the wearer's nose, mouth, and both cheeks; It is fused to form heterogeneous filters as a single article, and includes a filter 13 formed of a HEPA film to prevent inhalation of foreign substances together with the filter 20 by sewing while interposed inside the main body 11 There is a filter replaceable mask characterized in that,

In addition, Domestic Utility Model Publication No. 20-2020-0001613 (published date: 2020.07.20.) “While maintaining the shape of the existing mask, the earring strap or head strap is separated and combined, and the user adjusts and assembles it appropriately. and reusable mask structure” is known.

As described above, various known technologies related to masks are used, and among them, Patent Registration No. 10-1140281 provides a detachable mask that effectively blocks unnecessary inflow of external air and easily discharges internal air, a nose mask and mouth We provide a detachable mask that can be conveniently detached and worn, and a detachable mask that can be used by transforming the strap, and can effectively attach the nose mask and mouth mask to the user's face together, but the product assembly structure There is a problem that the production cost increases during manufacturing due to the complicated structure and the nose and mouth are separated, and there is a problem that it takes a lot of time to attach and detach from the fixing strap when attaching and detaching the mask. There is a problem of having to provide a length adjustment unit for adjustment.

In addition, in Korean Utility Model Publication No. 20-0204643, gaps between the face and the mask case and between the mask case and the filter are prevented, and the part except the filter can be used immediately after washing, but it is inconvenient to wear a mask In addition, there is a problem in that a production process must be added to provide a control strap, and it is possible to reuse the remaining parts except for the filter, but there is a problem in combining and assembling with the filter.

In addition, in Korean Utility Model Registration No. 20-0479660, a filter capable of effectively filtering fine dust is detachable with a fixing means on the inner surface of a mask having elasticity, so that the inner surface of the filter hygienically configured when wearing a mask is close to the nose. We provide a filter replacement type mask that increases the filtration effect by contacting the mouth directly and prevents inhalation of contaminants from the mask by non-contact with the mask, but a separate holding means must be provided to replace the detachable mask filter There is a problem that the strap cannot be adjusted, and the target that can be used is limited, so there is a problem in that products having straps of various sizes must be produced.

In addition, in Domestic Utility Model Publication No. 20-2020-0001613, productivity is improved by omitting the assembly process of earring straps or hair straps in the production process, and a shape that reduces the pressure applied by earring straps to the ears is devised, and earring straps or A method for adjusting the length of the head strap is proposed to increase productivity by omitting the ultrasonic welding process of the exhaust valve during production and to reuse the valve. There is no need for change in the existing production equipment, and there is no change at all in the frame of the existing manufacturing equipment, and some molding tools (ultrasonic molding rollers) are provided so that slight modifications can be made, but the position of the fixing part is different depending on the shape of the wearer's face. There is a problem that it is difficult to wear it stably, there is a problem that causes pain in the ear when a lot of force is applied to the ear, and there is a structural problem that is difficult to cleanly handle from the outside due to the cumbersome adjustment of the earring string. there is a fact
