Description

DETAILED DESCRIPTION OF THE INVENTION The most frightening things in the event of a fire are smoke, oxidized WE cavities and lack of oxygen.

However, if a fire occurs early, there is no need to worry about a fatal lack of oxygen.

Instead, breathing in soot, dust, and smoke containing carbon oxide often causes breathing difficulties and suffocation.

The boy loses his chance to escape and ends up dying.

The present invention is a smoke mask intended for emergency evacuation during the 20 to 30 minutes required for escape.

Next, its operation and effects will be explained with reference to figures.

It is impossible to eliminate smoke using conventional filters alone, but the present invention improves its effectiveness by combining electrostatic fishing and special filters.

What is shown in FIG. 1 is an example of a high voltage generation circuit using a semiconductor 1.
It operates using electric oil 2 as a power source, and generates high frequency and high voltage on the secondary side of the transformer 3.

This high voltage is transferred to capacitors 4, 4', 4' and commutator 5.
．． 5', 5'i times the voltage rectification to extract high voltage DC.

Connect this positive high voltage to the mesh electrode 6, and connect the ground side to 6.
A dielectric filter 8 is used for insulation between the N4M.

A fibrous activated carbon filter 7 containing a large amount of nitrogen element made of acrylic fibers is used at both ends of the filter.

When smoke passes through this special filter, it is removed by the filter and electrostatic precipitator.

This filter and 1tfi 13 are set in a mask 9, and a gas adsorbent 12 is also used for the purpose of removing carbon oxide, etc.
is set to 10 in mask 9.

Reference numeral 11 indicates the battery 2 portion of the power source.

Although this mask 9 is intended for emergency evacuation within 30 minutes, it can also be used for work purposes other than fire protection.
