Description

air purifier

technical field

The utility model belongs to the field of environmental protection and purification, in particular to an air purifier.

Background technique

At present, traditional negative ion air purifiers basically use needle-type negative ion generators to emit negative ions. This negative ion emission technology will release excessive ozone while releasing negative ions. Excessive ozone released is harmful to the human body. Moreover, the The amount of negative ions emitted by this technology is very small, generally only reaching 3 million/cm ³ .

At the same time, the traditional purifier is only composed of primary filter, HEPA filter, and activated carbon filter, which has a single purification function, does not have the ability to decompose harmful substances, and has relatively low purification efficiency.

Utility model content

In order to solve the above problems, the utility model provides an air purifier to increase the amount of negative ions produced and avoid the phenomenon of excessive ozone.

In order to achieve the above object, the technical solution of the utility model is: an air purifier, comprising a first housing with an air inlet and a second housing with an air outlet, the first housing is connected to the second housing The formed cavity is arranged in order to install the pre-filter, HEPA filter, activated carbon filter, photocatalyst decomposition layer and negative ion release layer;

The photocatalyst decomposition layer is mainly composed of an ultraviolet lamp and two layers of photocatalyst honeycomb ceramic sheets. The photocatalyst honeycomb ceramic sheet is located on both sides of the ultraviolet lamp and fixed by a fixed frame; the negative ion release layer is a carbon fiber negative ion generator controlled by low-voltage static electricity. , There are multiple carbon fiber anion generators, and they are fixed on the inner side of the second casing.

Further, the third housing with the control board is connected to the second housing, the fan is connected to the motor and installed in the cavity formed by the third housing and the second housing, and the installation position of the fan corresponds to that of the second housing. air outlet.

Further, an air quality sensing module is installed in the cavity formed by connecting the first housing and the second housing.

Beneficial effects: in the air purifier described in the utility model, the anion release layer is a carbon fiber anion generator controlled by low-voltage static electricity, and the number is multiple, so that the amount of anion generation is increased to twice or more than before, a breakthrough Instead of the traditional high-voltage electrostatic (above 10,000 volts) iron needles that release ozone exceeding the standard negative ion technology, low-voltage static electricity (below 3,000 volts, far below the Japanese standard of 8,000 volts) and carbon fiber needles are used as components for emitting negative ions, which can not only safely and efficiently It releases the original ecological negative ions, and because of its non-metallicity, it achieves the effects of never exceeding the standard of ozone and low power consumption. The air purifier of the utility model can generate negative ions up to -20 million pcs/cm ³ , and the purification effect can reach more than twice that of the traditional negative ion purifier. In addition, the use of nano-titanium dioxide photocatalyst (two-layer photocatalyst honeycomb ceramic sheet) can effectively kill a variety of bacteria, and can decompose and harmlessly treat the toxins released by bacteria or fungi, and the photocatalyst has a super self-cleaning function. The advantages of long service life and no need for replacement or cleaning effectively solve the fatal flaws of traditional photocatalyst technology.

detailed description

As shown in Figures 1 and 2, an air purifier includes a first housing 1 with an air inlet and a second housing 2 with an air outlet, and the first housing 1 and the second housing 2 are connected to form The cavity is arranged in order to install the pre-filter 3, the HEPA filter 4, the activated carbon filter 5, the photocatalyst decomposition layer 6 and the negative ion release layer 7;

Described photocatalyst decomposition layer 6 is mainly made up of ultraviolet lamp 61 and two-layer photocatalyst honeycomb ceramic sheet 62, and photocatalyst honeycomb ceramic sheet 62 is positioned at the both sides of ultraviolet lamp 61, and is fixed by fixing frame 63; There are multiple carbon fiber anion generators controlled by static electricity, and they are fixed on the inner side of the second housing 2 . Preferably, there are two carbon fiber anion generators.

The third housing 10 with the control board is connected to the second housing 2, the fan 8 is connected to the motor 9 and installed in the cavity formed by the third housing 10 and the second housing 2, and the installation position of the fan 8 corresponds to the first The air outlet of the second casing 2. The cavity formed by connecting the first shell 1 and the second shell 2 is also equipped with an air quality sensing module.

Its use method is: turn on the main power switch of the purifier, start the motor 9, and the unpurified air enters from the air inlet, and passes through the pre-filter 3, the HEPA filter 4, the activated carbon filter 5, the photocatalyst decomposition layer 6, and the release of negative ions. Layer 7, finally the purified air is discharged from the air outlet.
