Detailed Description

The invention will be further described with reference to the following drawings and examples:

embodiment 1, as shown in fig. 1 to 5, an air purifier includes a housing 1, a shield door driving device (not shown), a human body proximity sensor (not shown), and a shield door 13, where a cavity 11 is formed at a top of the housing 1, a top cover 2 is disposed at the cavity 11, and an air inlet 3 is formed in a gap between the top cover 2 and the cavity 11 and located at an inlet of a first filter layer 4.

The inner cavity of the shell 1 is sequentially provided with a first filter layer 4, a convection layer 5, a sterilization layer 6 and a second filter layer 7 from top to bottom. The first filter layer 4 is a filter layer for filtering particles such as hair, fiber velvet, particles, leather scraps, dust, pm2.5 and the like.

The troposphere 5 is provided with an air intake device, and the air intake device is a fan 8.

The sterilizing layer 6 is internally provided with an ultraviolet sterilizing lamp 9, the ultraviolet sterilizing lamp 9 is arranged at the central position of the sterilizing layer 6, and the ultraviolet sterilizing lamp 9 is an ultraviolet lamp tube.

The shell 1 is paved with an ultraviolet shielding layer 10 along the inner wall corresponding to the sterilization layer 6, wherein the ultraviolet shielding layer 10 is a titanium fluoride coating shielding layer, and can also be made of other materials to shield ultraviolet rays.

The shell is provided with a window 14 corresponding to the sterilization layer 6, the shielding door 13 is paved with an ultraviolet shielding layer 10, the shielding door 13 is arranged at the window 14 in a rotating mode, the human body proximity sensor and the shielding door driving device are arranged on the shell 1, and the shielding door 13 is connected with the shielding door driving device.

The second filter layer 7 is a manganese dioxide filter layer used for filtering harmful pollutants such as ozone, smoke, formaldehyde, VOC and the like.

An air outlet 12 is formed in the side wall of the shell 1, which is positioned at the outlet of the second filter layer 7, at the bottom of the shell 1.

The working principle is as follows:

after the air purifier starts, the fan 8 acts, the outside air enters the inner cavity of the shell 1 along the air inlet 3, and the outside air sequentially passes through the first filter layer 4, the convection layer 5, the sterilization layer 6 and the second filter layer 7 and is finally discharged to the air outlet 12.

Air purification and sterilization processes:

first filter layer 4 filters the air that gets into first filter layer 4, filters particulate matters such as hair, fibre fine hair, particulate matter, dander, dust, pm2.5, and the disinfection of disinfecting is disinfected to the air that gets into layer 6 to ultraviolet germicidal lamp 9 next, and the ultraviolet ray can produce ozone and effectively gets rid of organic matters and bacteria such as formaldehyde, VOC simultaneously. Then the second filter layer 7 filters the air entering the second filter layer 7, and the second filter layer 7 is a manganese dioxide filter layer which filters harmful pollutants such as ozone, smoke, formaldehyde, VOC and the like, so that sterile and clean air is formed and discharged to the air outlet 12.

When a human body approaches the human body proximity sensor, the human body proximity sensor sends a signal to the shield door driving device, and the shield door driving device drives the shield door 13 to act, so that the shield door 13 seals the window 14. At this time, the ultraviolet ray generated by the ultraviolet germicidal lamp 9 only sterilizes the air entering the germicidal layer 6, and at the same time, the ultraviolet ray can generate ozone and effectively remove organic matters and bacteria such as formaldehyde and VOC.

When a human body is far away from the human body and the sensor, the human body proximity sensor sends a signal to the shield door driving device, and the shield door driving device drives the shield door 13 to move, so that the shield door 13 opens the window 14. At this time, the ultraviolet rays generated by the ultraviolet germicidal lamp 9 sterilize the air entering the sterilizing layer 6 and the ultraviolet rays generated by the ultraviolet germicidal lamp 9 irradiate and sterilize objects outside the window 14 through the window 14, and simultaneously the ultraviolet rays can generate ozone and effectively remove organic matters and bacteria such as formaldehyde and VOC, thereby enlarging the sterilization area.

Embodiment 2, as shown in fig. 6 to 7, differs from embodiment 1 in that: in embodiment 2, the shielding door 13 is movably disposed at the lower portion of the window 14, and the shielding door driving device drives the shielding door 13 to ascend and descend, so that the shielding door 13 closes or opens the window 14.
