Description

Air purification fresh air machine

technical field

The utility model relates to an indoor ventilation device, in particular to an air-purifying fresh fan used in living rooms, shopping malls or offices.

Background technique

At present, the indoor ventilation rate of buildings is generally insufficient, resulting in frequent occurrence of indoor air pollution incidents. Some people experience symptoms such as headache, dry cough, dry itchy skin, dizziness, nausea, difficulty concentrating and sensitivity to smells. Various cancers such as lung cancer and blood cancer, among which the incidence rate of lung cancer has been ranked first, all developed countries have suffered painful lessons in this regard; this makes people begin to study and discuss the impact of indoor air quality on human health, pollution substances, their sources, and possible solutions.

To improve indoor air pollution, the most direct and effective way to improve indoor air quality is to improve indoor air circulation, accelerate the discharge of indoor polluted air, and accelerate the injection of outdoor fresh air. People generally adopt the following methods:

The first method is to open windows for ventilation. However, this most direct and original method of ventilation and exhaust is undesirable and has many disadvantages, because the ventilation direction of the window is blind, and the chaotic air flow may bring the peculiar smell of the bathroom and kitchen into the living room and bedroom, and entrain a lot of dust. While affecting indoor cleanliness, noise pollution cannot be avoided. Moreover, in the sultry weather when the outdoor air does not flow, even if the windows are opened, the indoor air will not produce convection. In addition, if the outdoor air is poor, it will pollute the indoor air instead.

The second is to use a ventilation fan. Although the traditional ventilation fan has a large instantaneous exhaust air volume, it cannot continuously eliminate indoor odors. The working state of on and off cannot continue to ventilate and ventilate. The ventilation range is narrow, and when there is no fresh air inlet, the exhaust resistance increases. The effect is greatly reduced.

Third, use air cleaners. However, after spraying the air freshener, the freshener mixes with the original turbid indoor air and adds a "camouflage" to paralyze the sense of smell, and the freshener itself contains harmful substances to the human body, resulting in a further decline in indoor air quality and secondary pollution. secondary pollution.

The fourth is to use indoor air purifiers. However, indoor air purifiers can only process the original indoor air, and as the indoor air pollution increases, its processing capacity gradually decreases. In addition, the air purifier can only absorb some harmful substances such as indoor dust, but does not have the ability to absorb harmful substances in the air and introduce the outdoor air into the room after filtering and purifying.

The fifth type is to use fresh air fans that filter and purify the outdoor air and introduce it into the room. For example, the Chinese utility model patent ZL200620151709.2 discloses the structure of this new fan, which consists of a casing, a control panel and a coarse filter layer installed in the casing. The motor and impeller are installed near the outdoor end, the coarse filter layer is installed on the indoor side of the motor, and the fine filter layer, activated carbon filter layer, negative oxygen ion generator and heating are installed in the casing of the coarse filter layer near the indoor side. device. Although the fresh air fan with this structure can filter and purify the air entering the room, since the motor and the impeller are installed at the end close to the outside, and the coarse filter layer is installed at the end close to the room, the flow of fresh air entering the room is very small, which is far from enough. To meet the indoor demand for fresh air, it is difficult to achieve the purpose of improving indoor air quality and ensuring human health. In addition, the rain cover needs to be installed from the outer wall, which poses a greater safety hazard when installed in high-rise buildings.

Therefore, compared with the prior art, the utility model not only has a simple structure for the air filter and purification device, but also has better performance of air filter and purification; Easy to maintain and clean.

As an improvement of the present utility model, the air filtration and purification device further includes an insect-proof net, and the insect-proof net is arranged outside the first dust removal filter net. The insect-proof net is preferably made of non-woven grid cloth or braided by metal wires. Such a structure can block insects such as mosquitoes and flies outside the first dust filter, so that the outdoor air can enter the room through the air filter and purification device more smoothly.

As another improvement of the present utility model, a second dust removal filter and an oil fume removal filter are sequentially arranged between the first dust removal filter and the bacteria removal net in the air filtration and purification device. A cold catalyst filter is arranged between the bacteria-removing net and the activated carbon fiber net, and a third dust removal filter is arranged inside the activated carbon fiber net. In the present utility model, the first, second and third dust removal filter screens are preferably made of non-woven fabrics; the oil fume filter screen is preferably made of polymer fiber materials; after adopting such a structure, the second dust removal filter The net is used to filter and purify the dust and floating particles with smaller particles that have not been filtered out by the first dust removal filter; the oil fume filter absorbs the oil fume particles in the air; Mercaptans are decomposed into harmless and odorless substances, transforming simple physical adsorption into chemical adsorption, decomposing while adsorbing, increasing the types of adsorbed pollutant particles, improving the adsorption efficiency and saturation capacity, without causing secondary pollution, and greatly prolonging the adsorption process. The service life of the material; the third dust removal filter screen filters and purifies the smaller dust and floating particles that are not filtered out by the first and second dust removal filter screens. It can be seen that the air filtration and purification device with this structure has achieved the best effect on the filtration and purification of outdoor air, so that even in the chemical industry area, the room can still breathe clean air.

As yet another improvement of the utility model, a rainproof cover integrally formed with the outer end of the casing is provided. The rainproof cover plays the role of rainproof and dustproof for the fresh fan of the utility model, and it is safe and reliable when installed in high-rise buildings, and safety accidents will not occur.
