JPH05168724A - Dustproof helmet - Google Patents

Abstract

PURPOSE:To incessantly feed clean air, warm air, or cold air to the head section of a worker so that the work can be performed healthily, safely, and comfortably in the environment with dust, a malodor, high temperature, or low temperature. CONSTITUTION:An air injection port is provided at the upper section of a dustproof helmet covering the whole head section and opened at the neck section, and a device feeding clean air, warm air, or cold air to the injection port from a blower 8 or an air compressor through a hose is connected to the injection port. A cock 9 adjusting the quantity of the fed air and a decompressor decompressing the compressed air are installed as required, and a heater or a cooler is added to the device when warm air or cold air is required.

Description

Detailed Description of the Invention

[0001]

[Industrial applications]

B. A lot of dust is generated during work such as concrete cutting work, rock excavation work, asbestos work, and clay processing work. Due to the respiratory action of the worker, such dust adheres to the lungs and has a bad effect on the human body. (B) When performing cleaning work, etc. in the poultry farm or pig farm,
It suffers from strong odor and dust. (C) When working for a long time at high temperature in steelmaking or casting, or when working in a freezer for a long time, the user may suffer from heat and cold. In the above cases, clean air, warm air, and cold air are passed from the head through the face to the neck and shoulders to prevent dust from touching the face and to alleviate the suffering of heat and cold. is there.

2. Description of the Related Art Such a device for protecting workers from dust and offensive odors is a dust mask or an odor mask, which is not a complete solution and completely eliminates the sources of occupational diseases. Does not meet

[0003]

The present invention was invented in order to meet the strong demands of such workers.
This is a work environment that allows you to work in dust, bad odor, high temperature, and low temperature in a healthy and safe manner.

[0004]

[Means for Solving the Problems] Means for solving the problems are
It is to supply the worker with clean air, warm air, and cold air necessary for the breathing action in a manner that is as close to the work as possible. B. Use a dust-proof helmet to cover the entire head, including the neck. (B) Clean air, warm air, or cold air is supplied from the top of the dustproof helmet. C. Supply air to the top of the dustproof helmet by connecting a hose to a blower or air compressor. D If necessary, change the temperature of the supplied air with a heater and cooler. E Adjust the amount of air to be supplied with a cock or valve, or if the work site to the air supply source is a long distance, pressurized air will be supplied.
With a suitable wind, the face is lowered from the head and discharged from the neck. (F) When the work area is fixed, an air supply source will be installed permanently. If not, carry a hose and all necessary equipment with you.
Air is supplied using a 0V or 12V power supply.

[0005]

[Operation] By wearing a dust-proof helmet, the worker can isolate his head from dust, foul odor, hot air, and cold air generated by work, and clean air, warm air, and cold air can cover his head. You can work in a comfortable state as you descend from the face and flow out from the neck. The influence of the wearing of the device on the work operation is hardly a problem.

[0006]

[Example] In a water pipe piping work, in order to cut a concrete floor surface, a concrete saw was used to cut concrete. With this work, concrete dust is scattered from the work site into a hemisphere with a radius of about 5 m,
The visibility was also around 1m. With a supply hose of about 20 m,
I was able to work cleanly and comfortably by supplying clean air from a place 15 m away from the work site. Occasionally there was some fluctuation in the dust scattering state due to the wind, but this did not affect the clean air supply. I lit a bonfire and experimented in the smoke. Smoke rising from the lower part could not enter the dust-proof helmet because it was supplied with the supplied air, and a comfortable breathing action was possible.
I didn't even smell the smoke.

[0007]

EFFECTS OF THE INVENTION In dust, bad odor, hot air or cold air, it is possible to work while breathing clean air, warm air or cold air, so there is no health concern. In addition, I was able to work with peace of mind because I did not feel stuffy when wearing a dust mask. Since the device is also convenient, it had almost no effect on the worker's work operation.
