Description

an air purifier

The utility model relates to an air purifier.

There are quite a variety of common air purifiers, with different price points, different working principles, and different composition structures. At present, there is an air purifier with a relatively good filtering effect of an air conditioner on the market, which is composed of a metal filter, an ion generator, a dust collector, an activated carbon filter, and a cation emitting needle behind it. The dust filtering method is to make the dust flow into the ion generator with positive electrons and electron ions, and the dust collector is placed in the purifier in parallel, and the dust collecting plates with positive and negative electrodes are arranged mutually, and each dust collecting The gap between the plates is not large, and all the dust is collected on the negatively charged dust collecting plate. Although the dust collecting plates have a large area and are arranged in parallel, so that most of the dust gathers at the front end of the dust collector, the amount of dust collected is not large. There are too many, and it is easy to cause blockage, which cannot achieve the proper dust collection effect. Once the dust cannot be collected, its effectiveness cannot be exerted, and it will directly flow to the activated carbon filter, which will increase the burden of dust collection on the activated carbon filter, and cannot achieve the purpose of filtering out odors and The effect of odor is due to the fact that today's office spaces are mostly closed spaces, and the outdoor air is also quite turbid. When the air conditioner is blowing for a long time and some large-scale air conditioners do not have the effect of ventilation, the air will become dirty very quickly. If someone is in a closed space Smoking in such a space accelerates the pollution of the air. Air-conditioning systems are commonly used to recirculate the air in the same environment. Many harmful gases and infectious bacteria are very easy to spread and breed rapidly in this environment. Some of these harmful gases Exhaust gas from outside industries and transportation, and the other part is the interior decoration of the building, air-conditioning pipelines and various pollutions. Therefore, the filtering effect must be quite good to meet the needs of the general public, otherwise it will cause office workers. Discomfort, affecting office efficiency, and even in the environment of medical facilities, tuberculosis, infectious hepatitis bacteria, Legionnaires' disease and airborne pathogens are everywhere in the air.

In addition to the limitations on the structure of the above-mentioned air purifier, it also has the following disadvantages:

1. When used in humid areas, it is easy to cause dust contamination to accumulate on the discharge needle, and the discharge needle is a metal cone, so the effect of discharging to generate free charges is limited, and the air purification effect cannot be fully exerted;

2. Due to humidity, the activated carbon filter material also reduces the actual filtering effect, and because of the peculiar smell of activated carbon itself, it becomes a kind of pollution;

3. Because the discharge needle is fixed on the inner edge of the body, when discharging, only rely on the natural circulating air in the room, so the range of the free effect is quite limited, and the air cannot be filled quickly, which greatly reduces the cleaning effect;

4. In the past, the high-pressure dust collection device was used. Due to the barrier of the activated carbon filter and the limitation of the one-way air inlet, it is necessary to start the motor and fan at the same time, so that the air can pass through the activated carbon filter above it and then flow to the air outlet on the top surface. Discharge, high power consumption and noise;

5. Even if the activated carbon filter is roughly filtered and the oxygen negative ions produced by the discharge needle, the vector bacteria produced in the aforementioned humidity and air cannot be digested and killed, and the purpose of purification cannot be achieved.

The purpose of the utility model is to provide an air purifier with good sterilization and dust filtering effect.

For reaching above-mentioned purpose, the utility model adopts following technical scheme:

The machine body of the utility model is provided with air inlets on four sides and air outlets with oblique upward blowing, which can expand the range of air circulation to fully mix the air in the room and ensure the cleanness of the air in the breathing area.

There are multi-layer filter cartridges, cross-type ultraviolet germicidal lamp tubes and related filter elements integrated in the body, which has the advantages of wide range of applicable objects, opportunities and occasions.

The multi-layer filter cartridge is covered with stainless steel mesh, activated carbon filter material and high-density glass fiber filter material, and activated carbon particles are built into it, which can eliminate odor and volatile organic compounds, and because it is very convenient to replace, it can be used for a long time Maintain air filtration and purification effects.

Because the body is equipped with ultraviolet germicidal lamps, it can eliminate the pathogens that cause tuberculosis, infectious hepatitis, Legionnaires' disease and any airborne pathogens.
