Description

Functional mask with length adjustment part

The present invention relates to a functional mask provided with a length adjustment unit, and in more detail, through holes formed by ear bands provided on both sides of the mask to catch the user's ears and adjustment units provided on both sides of the lower surface of the mask By using a pulling portion formed by passing the other side of the ear band, not only makes it easy to adjust the length of the ear band, but also allows the adjusted length to be stably maintained so that the mask is firmly attached to the face of the user. , This is a technical field related to a mask equipped with a length adjustment unit that can easily prevent harmful substances such as fine dust or yellow dust in the outside air from being directly inhaled into the user's nose and mouth.

In general, a mask serves to primarily prevent external cold air from directly contacting with the user's respiratory system in winter, and textiles, wood, paper, ready-mixed concrete factories, cement factories, briquette factories, coal mines, large-scale building construction sites. When working in a place with a lot of dust or fine pollutants generated in civil engineering works, chemical plants, welding plants, metal processing plants, etc., minute pollutants such as dust or toxic gas are directly introduced into the user's respiratory system and the human body such as lungs or bronchi It is used to prevent infection of the respiratory tract from being caused, or to prevent transmission of highly contagious viruses such as colds and flu through the respiratory tract.

In other words, a mask does not directly inhale infectious viruses transmitted to external cold air or respiratory systems, or dust and fine contaminants generated during construction site work, but inhales air that has contaminants filtered through a filter. Due to the occurrence of yellow dust or the occurrence of yellow dust, there is an increasing number of cases that need to be worn even when performing outside activities.

In addition, the conventional mask is composed of a body portion that covers the user's nose and the periphery of the mouth, a hook portion that can be worn on the ear, and a nose portion that can prevent contamination of external air from entering the nose portion. The main body part of the mask for blocking contaminants such as fine dust or yellow dust may include a filter that can block fine contaminants such as fine dust or yellow dust, and the hook part is generally applied with an elastic thread, which is convenient for users. In order to provide a length adjustment part, the nose part is generally a situation in which many products including a configuration of adding an iron core or aluminum or wire coated with a synthetic resin are being developed, When the user wears the adjusted mask, the adjusted length is not properly fixed, so there is a problem in that it is difficult to prevent contaminants from directly flowing into the respirator due to poor adhesion to the user's face.

As an example of the prior art of the conventional mask as described above, in Korean Utility Model No. 20-0485363, it is difficult to fasten the hook band to the ear, the strap is easy to break, and the strap is difficult to adjust, so the facial adhesion is poor, and foreign substances from the outside are easily inhaled. Unlike general masks or masks exclusively for fine dust or yellow dust, which have poor function, simple configuration that harmonizes with the face cover material with good filtration efficiency, and a simple hook-and-band combination structure that securely fastens without exposing the fastening part. Depending on the size, the length of the hanger band strap can be easily adjusted so that there is no gap between the mask and the skin of the face, and the adjusted strap is not easily separated from the hanger band length adjuster. We are presenting the equipped respirator health mask.

However, the prior art Republic of Korea Utility Model No. 20-0485363 describes the upper and lower bands of the mask when the user wears a mask for a long time or when the user releases tension due to the movement of the face or adjusts the hook band. Because it is reduced at the same time, it is difficult to adjust the hook band by repeating pulling or reducing, and it is difficult to adjust the hook band, and since the adjusted hook band comes out from the middle of the side of the mask, your fingers may touch the hair or receive a call. As the length of the band is changed by being caught by the hanging band, there is a slight inconvenience that the length of the hanging band must be adjusted by pulling or tightening it again.

As an example of the prior art of a mask for solving the above problems, Korean Patent Laid-Open No. 10-2004-0027268 relates to a disposable dust mask for preventing inhalation of dust or harmful substances, and the upper and lower portions of the disposable dust mask Each of the wearer's nose and chin is formed to form a bulge and welded with a hook band on both ends, but each fold of the filter paper and the end of the end of the filter paper form a step difference. While it facilitates cutting, ultrasonic welding is easy, and because the protruding part corresponding to the nose and chin part allows the mask to be worn in a more close contact without bending or forced pressure, it has a very excellent dustproof effect. Particularly, as the length of the hook band can be partially finely adjusted, the wearing comfort is improved, and a disposable dust mask that does not interfere at all even during sports or active movements by improving the adhesion to the user's face by the wrinkles and protrusions. Are presented.

However, the prior art Korean Patent Laid-Open No. 10-2004-0027268 requires that a step must be made on the entire finish of both sides of the mask, and the finish of both sides of the mask is formed by overlapping in a sandwich form, so manufacturing cost increases, and the finish is curved. Since it is not formed, there is a slight problem that when a user with a small face or a small cheek meat wears a mask, the feeling of close contact with the face decreases.

The present invention is a technology conceived to solve the problems according to the prior art described above, and the conventional mask capable of adjusting the length of the ear band is in close contact with the user's face after the length of the ear band is adjusted. When talking or making a phone call while wearing it, the adjusted length of the ear band becomes longer and the state in which the mask is in close contact with the face part becomes loose, and thus, there is a problem that the filtering of harmful substances by the mask is not performed smoothly. As a solution to this, the length of the ear band is easily adjusted using an adjustment unit that allows the other side of the ear band to pass in the horizontal direction, and the length adjusted ear band is bent 180 degrees by the adjustment unit, thereby stably It ensures that the adjusted length of the ear band is maintained, and as a result, the mask is firmly adhered to the user's face part, thereby providing through a functional mask equipped with a length adjusting part that allows the filtering of harmful substances to be stably and continuously maintained. It is for the main purpose.

In addition, the first and

second protrusions

30a and 30b formed on the outer and inner surfaces of the adjustment part 30, respectively, are formed such that the ends protrude in one direction, as shown in FIG. It is preferable that this realizes an effect of more efficiently preventing the ear band 20 from being pulled in the direction in which the length of the ear band 20 increases after being caught in the user's ear, and the one direction is the In the direction in which the length of the ear band 20 increases, it means a direction in which the ear band 20 protrudes in a direction opposite to the moving direction.

That is, the first and

second protrusions

30a and 30b formed on the outer and inner surfaces of the adjustment unit 30 respectively have the ear bands 20 in a direction in which the length of the ear bands 20 increases. It is characterized in that it is formed so as to protrude in a direction opposite to the moving direction.

In connection with the above, the adjusting part 30 of the present invention is formed to be spaced apart from the outer surface by a predetermined distance, the first passage hole 34a is formed in the horizontal direction, and is located under the first passage hole 34a. It is characterized in that it is configured to include an auxiliary adjustment unit 34 in which a second passage hole 34b is formed, and the auxiliary adjustment unit 34 is formed of the mask 10 after the ear band 20 is bent twice more. By allowing it to be bonded to the surface, the effect of more stably preventing the adjusted length from being varied is realized.

That is, the auxiliary adjustment unit 34 has the first and second passage holes 34a and 34b formed in the horizontal direction, similar to the adjustment unit 30, so that the user can easily adjust the length by pulling the ear band 20. In addition to increasing the number of times the ear band 20 is bent together with the adjustment unit 30, when the ear band 20 is caught in the user's ear and is pulled by elasticity, pressure, that is, tension ( Even if a pulling force) occurs, the other side of the ear band 20 that has passed through the first and

second passage holes

34a, 34b and the passage hole 32 is firmly fixed, so that the length of the ear band 20 is increased. It makes it possible to realize the effect of preventing more and more stably from being changed.
