Description

Insertion simple mask device {SIMPLIFIED MASK DEVICE}

The present invention relates to an insertable simple mask device used in workplaces, roads, and the like, where dust or fine dust is generated a lot, and more particularly, a filter bundle for easy separation and a size and a flexible material to be inserted into the nose. The present invention relates to an implantable simple mask device capable of preventing the penetration of yellow dust, dust or fine dust into the respiratory tract by inserting a soft tube into the nostril.

At present, there are many dusts and pollutants from industrialization and urbanization. Among them, fine dust in the form of fine particles floating in the air enters the body through the human respiratory system and has a very bad effect on the human body. In particular, heavy metals accumulate in the body without being discharged and cause fatal diseases.

In recent years, strong yellow dust from the deserts of China has caused respiratory problems in children, the elderly and many people working outdoors. In addition, strong yellow sand, which contains a lot of heavy metals, limits people's outdoor activities, which greatly affects the economic activity of the outdoors.

In such an environment, people who drive a lot of time in the city or on a day when there is a strong yellow dust, people who work outdoors, or work in various construction sites where there is a lot of dust, people who paint, Pesticide sprayers are often exposed to dust, paint dust, pesticides, automobile exhausts, yellow dust, heavy metals in the air, and wear masks to prevent them from entering the body.

Generally, a mask includes a mask made to cover both the nose and the mouth, which are the respiratory organs, and a mask or a stopper made to simply cover the nose. Among them, the plug has a small size, which is convenient to carry and can be easily worn. As an example of the above-mentioned koma dog, Korean Utility Model Publication No. 93-23082 (Nov. 25, 1993), Korean Utility Model Publication No. 96-33588 (1996.11.19), Korean Utility Model Publication No. 1999-35172 (1999.9) .6), there is an insertable mask or a simple mask device disclosed in Korean Laid-Open Patent Publication No. 2000-60444 (2000.10.16).

However, the above-described conventional insertable mask devices are formed in one piece or non-assembled type in which the filter is completely inserted into and fixed in the casing, making it difficult to separate the filter from the casing. Therefore, a short time after wearing the conventional device, the dust-proofing effect of the filter is lost or it is difficult to breathe, even if the filter is to be separated and cleaned or replaced, there is a disadvantage that the filter can not be easily separated and cleaned or replaced.

In addition, most of the conventional implantable mask apparatuses described above hardly pass moisture contained in the exhaled breath through the filter. Therefore, there was a problem in that the filter was wet and the filter was easily wetted so that the mask device could not be used continuously. In other words, the conventional insertable mask device has a disadvantage in that a filter installed therein does not pass the air smoothly due to the moisture contained in the breathing, and thus makes it difficult for the user to breathe.

The present invention is devised to solve the above-mentioned problems and to provide a more improved insertion mask device, the object of the present invention is to easily use in the workplace or yellow dust occurrence that the generation of dust is not so severe and small volume portable It is to provide a simple mask device that is easy to use, easy to fix in the use position and does not interfere with the activity even when worn.

In addition, another object of the present invention is to allow the outside air to enter through the filter when inhaling and to breathe out of the outside without passing through the filter when breathing out so that the filter does not get wet substantially even after long use. The present invention provides a mask device.

In addition, another object of the present invention is to provide an easy insertion type simple mask device that can be easily cleaned or replaced by removing the filter during or after the use of the simple mask device.

That is, air moves from the outer side B of the mask apparatus to the inner side A of the apparatus through the filter bundle 50 and is sucked into the body. At this time, the air is properly purified according to the type and function of the filter and enters the body. Therefore, the user can breathe smoothly even in a dusty or dusty environment.

In addition, when exhaling, the air in the body is introduced from the inside of the mask device A through the inner opening 6b of the soft tube 6 and discharged to the outside B of the device via the check valve means 8. At this time, the air is discharged directly to the outside through the check valve means 8, which is not installed through the filter substantially without passing through the filter.

As described above, in the second embodiment of the present invention, since the two soft pipes perform the functions of intake and exhaust at the same time, it can be used in a general case with a large amount of breath, and in the case of the third embodiment, a check valve having a structurally backward flow prevention function. Moisture exhaled by the means or runny nose can not contact the filter because the runny nose and moisture is generated a lot of contaminated filter easily can be used even when the mask device is difficult to wear mask device.

As described above, according to the present invention, since it is small in volume, it is easy to carry and is fixed simply by pushing it into the nose, it is easy to wear, fast, and can be worn confidentially. Has the advantage.

Also, in some cases, using a slightly larger soft tube can increase the size of the nostrils and increase the volume of breath. In other words, there is a lack of breathing through the nose due to excessive exercise, such as breathing in the mouth in this case, using a slightly larger soft tube has the advantage that it can smoothly breathe by increasing the size of the nostrils.

In addition, according to the present invention, when inhaling the outside air is introduced through the filter, and when exhaling the breath does not pass through the filter to the outside, the filter is not really wet, the advantage that can be used for a long time have.

In addition, according to the present invention, there is an advantage that the flexible tube can be used many times without replacement by inserting and fixing the filter bundle inside the flexible tube, or by easily removing and replacing it with a new one. That is, the filter bundle can be easily cleaned or replaced by removing the filter bundle during or after the use of the device.
