The present invention relates to a filter frame and a vehicle air filter formed with a filter filter made of a non-woven fabric therein, and more particularly, to form a support frame to facilitate the coupling and separation in the existing filter frame, and support The first and second potential generating members and charcoal filter members are formed inside the frame to filter and sterilize foreign substances, such as dust and dust, and molds and microorganisms, and to sterilize and sterilize them step by step, anion and ozone (O3). The present invention relates to a car air filter for purifying the air flowing into the car interior by using antibacterial and purifying action to create a comfortable indoor environment.

In general, the air in the air flowing into the car contains dust, pollen, dust, fine bacteria, and odors that cause allergies.In this way, the air flows into a closed vehicle without purifying the polluted air. If you do so, it can be unpleasant to the driver and other passengers, and it can be fatal to your health such as difficulty breathing. Therefore, dust, dust, and bacterial harmful substances contained in the air outside the car should be removed. It should be allowed to flow into.

To this end, as shown in FIG. 9, an air filter 1 is installed and used in an automobile air conditioner, and the air filter 1 used in this case repeats a filter filter paper 3 made of a nonwoven fabric with a triangular waveform many times. It is formed to be bent, and the filter filter paper (3) to form a filter frame (2) consisting of a rectangular box so as to be fixed therein and used to be mounted on the air inlet of the vehicle stably.

The filter filter paper 3 is a woven paper or non-woven fabric having a fine web, and serves to filter out dust or dust, and in particular, the filter filter paper 3 is a continuous triangle to increase the contact area with air per unit area. It has a shape bent into a waveform. In addition, the filter frame (2) is obtained by inserting the filter paper into the injection machine, spraying the PP resin or ABS resin raw material at a high pressure in the outer frame portion, and cooling, the filter paper (3) in the cooling process 2) Attached and fixed.

The fixed filter filter paper (3) has a simple structure that is fixed to the filter frame (2) in a state where the nonwoven fabric or the synthetic fiber is composed of one or two layers simply, so that the dust of relatively large particles may be filtered out. Fatal fine dust or dust had a problem that can not pass through as it is not filtered.

In addition, if the air filter is not frequently replaced, microorganisms such as mold or bacteria have been raised, which has been raised as a problem.

Recently, in order to secure such a problem, a technique of releasing anions and installing antibacterial and deodorizing charcoal at the air inlet has been introduced, but in this case, it is inconvenient to replace the installed charcoal because the coal is put into the air inlet as a lump. There was a point.

On the other hand, in order to secure the above problems, the technology used to fix the filter filter paper 3, which is used to apply activated carbon or charcoal to the non-woven fabric to the filter frame 2 has been applied for, the air filter 1 is activated carbon In the method of coating the charcoal, there is a problem that the air flow is not smooth because the web of the nonwoven fabric is blocked due to the minute difference between the content of the charcoal and the content ratio of the adhesive for attaching the charcoal to the nonwoven fabric.

Since the filter filter paper 3 is integrally fixed to the filter frame 2, when the filter filter paper 3 has reached the end of its life, only the filter filter paper 3 can be separated and replaced. There was a problem to use and exchange as a whole.

In addition, the filter filter paper (3), which is simply coated with charcoal on a single nonwoven fabric, has a problem in that the antibacterial function due to the generation of negative ions is remarkably inferior in its working effect.

In order to maximize the function of the negative ions as described above, air cleaners are widely used to purify the indoor air using an anion generator, but such air cleaners can be directly introduced through the air conditioner and the foreign substances and mold and There was a problem that can not remove the microorganisms.

In the case of negative ions generated in air cleaners, ozone (O3) is generated as a by-product when negative ions are generated. The higher the concentration of ozone is, the worse the health. A very serious problem that causes nausea and even severe vomiting has been pointed out.

Especially for pregnant women, the elderly and children, it can be fatal to the health and cause headaches in the driver.

The present invention has been made in view of the above-mentioned conventional problems, and an object thereof is to form a support frame so as to be economically easy to manufacture and to easily combine and detach the support frame inside the filter frame, thereby improving the working process of the air filter. It is to provide a car air filter that can reduce the cost of products by shortening and improving productivity.

Another object of the present invention is to provide a vehicle air filter that can be used semi-permanently by solving the problem that the existing filter is periodically replaced by using.

Still another object of the present invention is to provide an air filter for automobiles that forms a filter member inside and behind the support frame to increase the filtration effect and to recycle the support frame by replacing only the filter member after long time use.                         

Another object of the present invention is that when a current is applied to the first potential generating member formed in the vertical direction in front of the support frame, the current is amplified in the circumferential direction, the negative ions act in every corner of the support frame, the negative ions and the char filter member A large amount of negative ions generated from char are generated for a long time while being in electrical contact, minimizing the concentration of ozone (O3) by antibacterial action, and removing fungi and microorganisms such as mold and microorganisms to maintain pleasant indoor environment. An automobile air filter is provided.
