Description

Sterilizing air purifier

technical field

The utility model relates to an air purifier for sterilizing indoor air, which belongs to the technical field of indoor air conditioning.

Background technique

Currently commercially available indoor air purifiers are varied, but most of them are filter-adsorption type, which utilize fan to force air circulation, so that the air can be purified through filtration and adsorption media. However, because the filter medium is easy to be blocked and the adsorption medium is easy to reach saturation, the harmful pollutants adsorbed on the medium can be emitted, and at the same time, some harmful gases cannot be efficiently adsorbed, so the efficient purification effect cannot be achieved. However, the use of electrostatic precipitators for purification cannot effectively eliminate negatively charged particles such as suspended dust and other harmful gases; in addition, static electricity generates a large amount of ozone and discharges it indoors. Uncomfortable feeling reduces the purification effect. At the same time, the pollutants after electrostatic dust removal will be deposited on the dust collection plate, causing secondary pollution.

The utility model sterilizes and sterilizes the air purifier, wherein the primary filter screen is several layers of filter cotton or black sponge treated with antimicrobial substance AM500.

The utility model sterilizes and sterilizes the air purifier, wherein the ultraviolet lamp is tubular and placed in a horizontal direction, and the photocatalytic plate is placed between two ultraviolet lamps and installed in parallel with the ultraviolet lamp tube.

The sterilizing and disinfecting air purifier of the utility model has four ultraviolet lamps and three photocatalytic plates.

The utility model is a sterilizing and disinfecting air purifier, wherein the fan is composed of a motor, a wind wheel and a fan cover, the fixed plate on which the motor is installed is connected and fixed with the inner sleeve, the wind wheel is fixed on the rotating shaft of the motor, and the fan cover is connected with the inner cover and the fixed plate. The connection is fixed, and the inner sleeve is installed on the bottom plate; the air inlet channel of the fan formed between the fan cover and the back plate communicates with the filter, and the air outlet of the fan faces upward and communicates with the diversion channel.

The utility model is a sterilizing and disinfecting air purifier, wherein the output end of the negative oxygen ion generator installed in the cabinet communicates with the diversion channel.

The utility model sterilizing and disinfecting air purifier has the following advantages:

1. The primary filter has been treated with AM500, which has changed the many shortcomings of traditional antibacterial products that use heavy metals or chemical substances for antibacterial. It uses water as a solvent, is non-toxic and harmless, and does not cause any pollution, eliminating the impact on the environment and people. security risks. It can efficiently adsorb and kill pathogenic viruses in the air, and the antibacterial rate is over 90%. Especially anti-Staphylococcus aureus, Escherichia coli, Bacillus subtilis black variety, Candida albicans, methicillin-resistant Staphylococcus aureus all reached 99.99%, and anti-Klebsiella pneumoniae reached 95%. It can also effectively resist influenza virus A, herpes simplex virus I, HIVB and various viruses infected from the respiratory tract. At the same time, it has the function of reducing the content of harmful substances such as stupid series in the indoor air and the antistatic function, so that the filter cotton is prevented from dust adhesion and odor. Thereby enhancing the toughness of the filter and prolonging its service life.

2. Use photocatalytic plates to enhance the sterilization and disinfection effect of ultraviolet lamps. At the same time, it can absorb some volatile organic gases that cannot be adsorbed by traditional activated carbon, such as formaldehyde, which improves the air purification rate.

3. The filter made of high-efficiency filter material can effectively remove particles above 0.3 μm, and its efficiency of capturing inhalable floating pollutants by the human body is as high as 99.99%.

4. Increasing the release of negative oxygen ions can balance the ions in the air, purify the fresh and warm air, and make people enjoy the comfort of bathing in the big forest indoors.

5. The ultraviolet light for sterilization and disinfection is installed inside the purifier to avoid the harm of long-term ultraviolet light to the human body.

FIG. 2 is a schematic diagram of the cross-sectional structure along line A-A of FIG. 1 .

Detailed ways

It can be seen from Fig. 1 and Fig. 2 that the embodiment of the utility model is designed as a cabinet type, and the bottom end is connected and fixed by the inner sleeve 4 and the bottom plate 1 as a base body, and the primary filter 3 installed in the air inlet grille 2 is installed in the inner sleeve The ultraviolet lamp 17 in 4, the photocatalytic plate 16 and several layers of filters 14 made of high-efficiency filter materials form a sterilization and disinfection device; under the action of the fan, the dirty air enters from the air inlet grille 2 and passes through the primary filter screen 3 in turn. Remove microorganisms such as bacteria and viruses, remove toxic and other harmful substances through the photocatalytic plate 16, and further kill bacteria and viruses in the air through ultraviolet light irradiation, and then filter dust and dust through several layers of filters 14 made of high-efficiency filter materials Suspended particles are sent into the guide channel 12 above through the fan air inlet channel 15 formed between the fan cover 5 and the back plate 13, and are blown out from the air outlet 10; at the same time, an appropriate amount of negative oxygen ions is generated by the negative oxygen ion generator 19 It also enters the diversion channel 12, mixes with the purified air and enters the room. Increase the appropriate amount of negative oxygen ions because air pollution gradually reduces or disappears negatively charged ions, and at the same time produces too many positive ions, which will have adverse effects on human health.
