Description

Mask that is improved inpracticality

The present invention relates to a mask with improved practicality, and more particularly, a removable intake purifying part is provided on one or both sides of a repeatedly washable face shield, and a shape maintaining member is configured on the inner surface of the face shield so that the face shield is worn by the wearer. It relates to a mask with improved practicality that allows purified air to flow into the inside of the face shield while being spaced apart from the face of the mask to reduce the stuffiness caused by wearing the mask.

The mask referred to in the present invention relates to a disposable health mask that simultaneously covers a part of the wearer's face, that is, the nose and mouth of the wearer, and is used in the meaning except for a gas mask that covers the face or the entire head.

As it is known that the increase in fine dust in the air due to environmental pollution is involved in various respiratory diseases, the use of masks when going out is gradually increasing.

In addition, in recent years, due to the emergence of viruses that cause various lung diseases, the virus enters the human body through the respiratory system or the virus contained in the droplets of others penetrates into the respiratory tract of the other person during conversation, resulting in a large number of patients due to indiscriminate transmission. The importance of wearing a mask is being emphasized once again as the number of casualties has increased significantly, causing a global problem.

Masks are considered as one of the most preemptive preventive devices to prevent pollutants in the air or various harmful viruses contained in the other person's droplets during conversations from penetrating into the human body through the respiratory system. is being recognized

In general, health masks sold on the market are sold separately for fine dust prevention, yellow dust prevention, and virus penetration prevention according to their functions. .

Therefore, when a highly contagious virus is prevalent as in recent times, the demand for masks increases explosively and the supply of masks is insufficient, resulting in a mask crisis. Of course, the vicious cycle that causes environmental pollution problems is bound to repeat itself and occurs, and skin diseases caused by long-term wearing of disposable masks are also occurring.

In addition, when wearing a conventional health mask, discomfort occurs when breathing or speaking while the nose and mouth are in contact with the face shield, and the air discharged during exhalation without inflow of fresh air is respirated when breathing in. It not only causes breathing difficulties, but also causes a lot of reluctance to wear the mask because the face covering and the face are in close contact.

In addition, in the case of a conventional disposable health mask, when the rim part is lifted from the face, the penetration of contaminated external air is easy. There was a problem.

- Patent Registration No. 10-1941856 (2019.01.18) - Patent Registration No. 10-1797071 (2017.11.07) - Patent Registration No. 10-1785804 (2017.09.29)

This has been devised to solve the problems of the conventional disposable mask described above, and it enables repeated use of the face shield, which is the main body of the mask, thereby reducing the loss of resources due to the use of the disposable mask and reducing environmental pollution problems. , It is an object of the present invention to provide a mask with improved practicality that allows for comfortable breathing of the mask wearer by supplying purified air to the inside of the face shield by forcibly introducing outside air.

In addition, the present invention enables the smooth circulation and use of purified air by configuring the face shield located on the face part of the mask wearer to be spaced apart from the face part at a certain distance, and to relieve the discomfort of the mask wearer due to contact between the face shield and the face part. Another object is to provide a mask with improved practicality that can solve the problem.

The mask having improved practicality according to the present invention for achieving the above object is a face shield made of a material that can be washed repeatedly while being sized to cover a part of the wearer's nose, mouth and face, and both sides of the face shield It is provided with a fixing part that is provided over the user's ear to fix the face shield to the user's face part, and the inner center part of the face shield is spaced apart from the face part by a certain distance while worn on the user's face part. A face shield shape maintaining member that is installed in a curved shape on the inner surface of the face shield is provided, a through hole of a certain size is formed on one side or both sides of the face shield, and external air is forcibly sucked and purified to the inside of the face shield.

External air forcibly introduced into the housing due to the rotation of the fan motor, and the external air forced into the housing passes through a purification filter provided inside the housing to filter out various contaminants, and then the exhaust hose and the purification connected to the exhaust hose The air is introduced into the air communication unit at the upper end of the face shield shape maintaining member through the air inlet hose.

The purified air supplied to the air communication unit is supplied to the space between the wearer's face part and the face shield through an air discharge hole formed at the bottom of the air communication unit, so that the mask wearer can breathe comfortably through the inhalation of the purified air introduced. .

In addition, when the intake purifiers 40 are provided on both sides of the face shield 10 of the mask 100, the mask wearer does not operate the two intake purifiers 40 at the same time, but operates it from either side of the intake purifiers to obtain an appropriate amount. It provides the advantage of being more beneficial when working while wearing a mask for a long time by receiving the purified outdoor air of

In one embodiment shown in the accompanying drawings, the fixing parts 20 provided on both sides of the face shield are made in a thin band shape, and if necessary, both fixing parts are configured in the form of a hood that wraps around the back of the mask wearer's head. It may be configured as a structure that can be fixed by interconnecting with Velcro tape or the like.

In addition, on one side of the housing of the intake purifier, a charging/discharging indicator light is installed to display the charging/discharging status so that the user can conveniently grasp the charging/discharging timing of the battery that is mounted inside the housing and supplies the power required to drive the fan motor. A predetermined electronic board required for control and operation of the fan motor may be configured inside the housing, and such electrical and electronic components can be easily devised by those skilled in the art through known techniques. Since it is possible, a detailed amplification of this will be omitted.
