Description

Automotive air filter {Automobile air filter}

The present invention relates to a filter frame and an air filter for a vehicle in which a filter filter paper made of a non-woven fabric is formed therein. More specifically, step by step of breeding and odor of foreign substances such as dust, dust, and mold or microorganisms introduced into the vehicle. A plurality of filter members are provided inside the filter frame so that the filter frame can be removed, and the air flowing into the vehicle interior can be purged by filtration and sterilization, antibacterial and purification using anion and ozone (O ₃ ) to create a pleasant indoor environment. It is to provide an air filter for automobiles.

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 passengers, and it can be fatal to your health such as shortness of breath. Therefore, dust, dust and bacterial harmful substances contained in the air outside the car should be removed from the inside of the car. It must be possible to flow in.

To this end, as shown in FIG. 8, 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 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 (O ₃ ) is generated as a by-product when negative ions are generated. The higher the concentration of ozone is, the worse the health and the person breathing indoors when exposed to ozone for a long time. Is a very serious problem that causes nausea and even severe vomiting.

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 conventional problems, and its object is to provide a plurality of filter members, a potential generator, and a charcoal filter inside the filter frame, such as foreign substances, molds, microorganisms, etc. Filter and sterilize the breeding and odor of each step, and provide air filter for automobile to create pleasant interior environment by antibacterial and purifying effect using negative ion and small amount of ozone by action of potential generator and charcoal filter. Is in.

Another object of the present invention is to provide a vehicle air filter that is easy to use and can be used by recycling only the filter member formed in the front and rear after a long time use.

Another object of the present invention is to form an auxiliary hole in the center of a pair of two pairs of potential needles, when a high pressure current is applied to the first electrode plate, anion is generated in the potential needles, and a large amount of air is sucked through the auxiliary holes. The present invention provides an air filter for an automobile that accelerates the strength of the negative ions so that the negative ions can be moved forward.

Still another object of the present invention is to form a plurality of guide holes in the inner surface of the charcoal filter member, the dislocation needle is inserted into the guide hole so that the electric potential is applied to the dislocation needle in electrical contact with the charcoal filter member At the same time, more anions are generated than at the same time, while minimizing the concentration of ozone (O ₃ ) by the antibacterial action of the charcoal filter member. The present invention provides an air filter for an automobile.

1 is a perspective view of a separated state showing the overall structure of the present invention, Figure 2 is a cross-sectional view showing a combined state, the present invention air filter 1 is made of a hollow rectangular shape as shown in FIG. The filter filter paper (3) made of a filter frame (2) and a non-woven fabric to be fixed therein is bent to repeat a triangular waveform a number of times, and is configured in the air filter (1) for automobiles to purify the air flowing into the vehicle. In the filter frame 10, a copper-impregnated or coated first filter member 20 inside the filter frame 10, a potential generator 30 for generating anions and ozone, generating anions and concentration of ozone Charcoal filter member 40 to minimize the second, the second filter member 50 is impregnated or applied to the sterilization and purification action, and the power supply device 60 for supplying power to the potential generator 30 It is constructed.

Hereinafter, the present invention will be described in detail with reference to the accompanying drawings, and the handle part of the filter frame 2 will be omitted and described.

As shown in FIG. 1, the present invention enables easy coupling and separation to the existing filter frame 10, thereby reducing the cost of the product, and excellently filtering, sterilizing, antimicrobial, and purification functions to maintain a comfortable interior of the car. It is provided with an air filter (1).

On one side of the filter frame 10, the connection hole 11 is formed in the upper and lower portions so that the potential generator 30 and the power supply device 60 to be described later can be electrically connected.

On the other hand, the first filter member 20 is installed in front of the filter frame 10, wherein the first filter member 20 is to contact the outside air when collecting the inside of the vehicle air conditioning apparatus to collect the large particles of dust primarily The fine powder is impregnated or applied to the nonwoven fabric so as to be impregnated or coated so that foreign substances, such as dust and dust, which pass through the first filter member 20 can be filtered and sterilized to be purified first.

Here, the nonwoven fabric of the first filter member 20 can be used in various ways.

First, a nonwoven fabric having a plate shape, and impregnating or applying copper to the surface of the nonwoven fabric, first, in the process of applying copper to the nonwoven fabric, the adhesive should be used in order to bond the copper to the nonwoven fabric. According to the ratio of the non-woven web (web) is clogged, there is a problem that the air flow is not smooth, so in the present design, after processing the copper into fine powder, the copper powder 65-75% (weight ratio) and adhesive 25-35% ( Weight ratio), and then evenly sprayed copper powder on a nonwoven fabric consisting of a flat plate and dried for a predetermined time.

The first filter member 20 completed by the above process is fixed to the filter frame 10 by fixing with an adhesive or ultrasonic welding to the filter frame 10, wherein the first filter member 20 is used Each nonwoven fabric formed in a plate shape may be bent so that a triangular waveform is repeated a plurality of times so that a foreign matter is in contact with copper so as to have a wide contact area.

Meanwhile, as shown in FIG. 3, the first filter member 20 fixes both sides of the first filter member 20 having a plate shape to the filter frame 10 so that foreign matter passes through the first filter member 20 in a short time. By the potential generator 30 and the charcoal filter member 40 to be described later to be filtered, sterilized, antibacterial and purified.

The potential generator 30 is composed of a first electrode plate 31 and a second electrode plate 37, wherein each of the electrode plates 31 and 37 is most preferably formed of copper, and in some cases Silver may be used by plating gold and silver.

The first and second electrode plates 31 and 37 are formed of a plate body and bent at both ends so that the U-shaped shapes face each other, and the semi-circular holes 33 are formed on the surface of the first electrode plate 31. A perforated and triangular dislocation needle 34 forwardly integrally bent at one side thereof and forms an auxiliary hole 35 on one side of the potential needle 34, and has a semicircular hole centered on the auxiliary hole 35. A pair of dislocation portions 32 is formed such that the 33 and the dislocation needle 34 face each other.

The dislocation part 32 is repeatedly formed vertically, vertically, and downwardly at a predetermined interval, and a plurality of through holes 36 are formed between the dislocation part 32 and the dislocation part 32 to form a plate. When the first electrode plate 31 made of a sieve is entirely sealed, a negative (-) high voltage current is applied to the first electrode plate 31, and the air at the tip portion of the potential needle 34 causes insulation breakdown and is weak. As the current is amplified while emitting light, anions and ozone are generated. At this time, the anion and ozone generated by the advancing in the horizontal direction are somewhat reduced, so that the anions cannot be transmitted far, but the first electrode plate of the present invention ( 31 is formed in the hole 33, the auxiliary hole 35 and the through hole 36, the electrons inhale the outside air when moving to increase the strength of the wind so that the negative ions can move far.

The anion generator used in recent years is composed by separating the precipitation electrode and the plate electrode and sending high voltage current to the precipitation electrode and grounding the plate electrode to generate the anion. In the case of the precipitation electrode, the conical precipitation electrode is fixed to the plate. Even when negative ions are generated, the distance to move in the horizontal direction is insufficient, so that negative ions do not substantially clean indoor air.

In order to secure such a problem, the auxiliary holes 35 are formed between the dislocation needles 34 on both sides to increase the moving speed of the electrons so that the negative ions can move far.

In addition, a second electrode plate 37 having a circular hole 38 and an auxiliary hole 39 is formed on the opposite side of the first electrode plate 31 so as to conduct a positive current.

The charcoal filter member 40 used at this time has a plurality of guide holes in the inner surface. 41) to have a structure in which the dislocation needle 35 is inserted therein and protrudes forward so that anion is ionized when an electric current is applied to the dislocation needle 35, and electrical contact is made at the inner surface of the guide hole 41. As a result, a larger amount of negative ions are continuously generated in a shorter time than the number of naturally occurring negative ions. And while ozone generated from the potential generator 30 passes through the charcoal filter member 40, a small amount of ozone acts as the concentration of ozone decreases. At this time, the acting ozone has a strong bactericidal power and removes bacteria and viruses. It has strong bleaching and antimicrobial treatment of foreign matters, molds and microorganisms in the interior of the car with excellent effect of harmless reaction with organic substances such as odorous gas and various harmful substances.

The second filter member 50 is installed at the rear of the potential generator 30, where the second filter member 50 impregnates or applies a sound made of fine powder and finally sterilizes and purifies the remaining foreign substances. The indoor air can be kept comfortable.

The power supply device 60 is electrically connected to the potential generating device 30 to supply a negative current to the first electrode plate 31 and a second electrode plate (+) current to the first electrode plate 31. If the negative current is 7.5V, the positive current is differentiated by 5V so that a large amount of negative ions can be generated.

On the other hand, the power supply device 60 is installed separately from the inside or outside of the air conditioner to be used in electrical connection with the potential generator 30, or installed on one side of the filter frame 10 as shown in Figure 5 filter frame By connecting with the potential generating device 30 through the electrode hole 11 of the (10) and simply coupled and separated to facilitate the handling and repair work when a lover, such as a failure occurs.
