JP6262059B2 - Respiratory cover - Google Patents

Description

  The present invention relates to a cover for a respirator or a dust mask, and more particularly to a cover for protecting a filter attached to an outside air intake port of a respirator used particularly in civil engineering and construction work sites.

Many respirators or dust masks have been proposed, and are intended only to cover the mouth and nose from high-end specs that excel in dust collection and ventilation, and performance in removing attached dust. There is even a simple one. On the other hand, in order to ensure the safety of workers, a mask equipped with an electric fan that can instantaneously remove dust and maintain a clean state, and a high function that can supply oxygen constantly by connecting with a blower and a hose A mask has also been developed. (For example, JP2002-219184, JP2002-177408, etc.)
Generally, in civil engineering and construction sites, working in harsh spaces where dust always floats is unavoidable, but it has performance according to the working environment, is small and lightweight, and is easy to work with. There were no respirators or dust masks that had a large particle size and long-lasting performance against large amounts of dust.

In civil engineering and building construction sites, since workers work while moving, a small and lightweight mask that does not interfere with work is required. In addition, underground work that involves excavation of the ground and removal of earth and sand, and the face of tunnel construction, a large amount of moist dust is generated, so moisture adheres to the mask along with dirt due to dirt, and the mask must be replaced frequently. There is a case.
In order to reduce the replacement frequency, it is necessary to maintain the performance for a large amount of dust having a relatively large particle size. If there is a cover that can be exchanged by attaching it to the outside air inlet of a commercially available respirator or dust mask, water droplets containing dust can be prevented from adhering to the filter, or the dust collected on the filter can be encouraged to fall. As a result, the performance of the filter and thus the protective equipment for breathing lasts longer.

The cover of the respirator of the present invention is a detachable cover for protecting a filter attached to the outside air inlet of the respirator. That is, a cover for a respirator, which covers a filter attached to an outside air intake port of the respirator, wherein a brush whose tip is in contact with the filter is implanted inside the cover. is there.
Furthermore, the brush may be made of carbon fiber.

If the cover of the respirator of the present invention is made of a lightweight material such as plastic, it can be easily attached and fixed to a commercially available respirator, and it is small and lightweight and does not hinder the work. Also, since the filter attached to the outside air intake port of the respirator is not directly exposed to the front, water droplets containing dust are prevented from directly attaching to the respirator filter during work.
In addition, since the brush with the tip in contact with the filter is planted inside the cover, the filter surface is wiped with the brush due to the vibration caused by the breathing of the filter and the vibration caused by the work, and the dust collected on the filter is encouraged to fall. The filter and thus the performance of the respirator lasts longer.

It is sectional drawing of the cover of the respirator which concerns on embodiment of this invention. It is the longitudinal cross-sectional view and side view at the time of installing the cover of the respirator concerning the embodiment of the present invention.

  The present invention relates to a cover for a respirator or a dust mask, and more particularly to a filter for protecting a filter while being detachably attached to an outside air intake port of a respirator used particularly in civil engineering and construction sites. Regarding the cover.

Hereinafter, embodiments of the present invention will be described with reference to the drawings. In FIG. 1, a cover body 1 is made of plastic and covers a filter portion attached to an outside air intake port of a commercially available respirator, and has a cup shape that can be fixed by insertion. An outside air inlet 3 is opened in a part of the side surface of the cover.
Furthermore, a brush 2 whose tip is in contact with the filter is planted inside the cover. In FIG. 2, the longitudinal cross-sectional view and side view at the time of installing the cover of the respirator of this invention in the commercially available respirator with an electric fan are shown.

If the cover of the respirator of the present invention is made of a lightweight material such as plastic, it can be easily attached and fixed to a commercially available respirator, and it is small and lightweight and does not hinder the work. Also, since the filter attached to the outside air intake port of the respirator is not directly exposed to the front, water droplets containing dust are prevented from directly attaching to the respirator filter during work.
Furthermore, since the carbon fiber brush 2 whose tip is in contact with the filter is planted inside the cover, the surface of the filter is wiped with the brush 2 due to the vibration caused by the breathing of the filter or the vibration caused by the work, and collected in the filter. Dust fall can be promoted, and the performance of the filter and thus the respirator will last longer. Since it is a carbon fiber brush, static electricity is hardly generated by friction.
