Abstract

"AIR PURIFIER" PROTECTS PEOPLE INSIDE MOTOR VEHICLES FROM POLLUTION

Abstract The "AIR PURIFIER" invention is a pollution cleansing system inside motor vehicles for the protection of the occupants.
The "Air Purifier" is built into the cowl plenum chamber of the heating-cooling system and in the side vents. This "Air Purifier" is inside the container of the filter which is composed of the appropria-te components to remove pollutants from the air. This "Air Purifier"
prevents pollutants, such as noxius fumes of carbon monoxide, smoke, and dust from entering the motor vehicle interior. The increase of motor vehicles in use today has resulted in a concomitant increase in air pollutants on the roads. As a result, pollutants are being inhaled by drivers and passengers. By installing the "Air Purifier" in motor vehicles we can be assured of breathing purer air.

This invention relates to the use of the "~ir Purifier", in our automobile, to cleanse -the air which is polluted. A container of appropria-te size with inflow and outflow openings, containing on the lnside a filter composed of the appropriate components for the occu-pants. Ihe inflowing air containing pollutants is cleansed by the "Air Purifier".

_ CKG~OUND ART

The aim of the "Air Purifier" invention as applied to passengers motor vehicles is to protect health and in certain cases prevent outright poisoning. The whole world i8 becoming one great highway owing to the greater availability of motor vehicles to people the world over. The only air that the driver and passengers 15 can breathe is that air in the motor vehicle but which enters the interior through inlets in the heating-cooling system and also side ven~s. That air i9 polluted by the fumes emitted from the motors of passing motor vehicles. One of the best solutions to this problem is to use an "Air Purifier". me moment this invention is 20 used in motor vehicles it will certainly ensure health and in some cases prevent poisoning.

DISCLOSURE OF THE INVENTION

Many years passed cince the invention of the motor vehi-cleO ~oday, there millions of them and mor and mor that make use of ~,. -- 1 --fuel, diesel fuel and alcohol. Built in varios sizes, they burn these various fuels and emit noxious f~nes that pollute the air. ~nese motor vehicles are used for various purposes, to transport peoples in buses, for instance. Certain jobs require that we spend many hours in motor vehicles. Almost every working person uses a motor vehicles and uses it for various r~asons. In all of this we inhale -the polluted air. ~o this day all that has been done to protect people from the exhaust fumes is -to have installed an exhaust system converter and a portion of the exhaust fumes returns for a secondary burninæ.
One of the greate~t needs in our motor vehicle today is to install an "Air Purifier", which will cleanse the air of pollutants in-to our motor vehicle. Such an "hir Purifier" would be installed in the cowl plenum chamber. It would be ins~alled in the place that would put it in line with the air being pulled into the motor vehicle by the blo-wer and in the side vents in the air supply that flows from the exte-rior to the interior. This "~ir Purifier" will be equipped with a sen-sor switch that notifies the driver whenever the "~ir Purifier" becomes dirty and needs to be replaced. This sensor switch is closed by a spring thus causing the warning light designating the "Air Purifier" to illumi-nate on the instrument panel. I~hen the '?Air Purifier" is clean the use of a blower will cause the air to push away the sensor plate preventing the warning light on the instrument panel from iluminating. When the "Air Purifier" becomes dirty the air being drawn by the blower will diminish in strangth and no-t be able to move the sensor plate and thereby cause the warning light to iluminate.
