[0020] The filter core assembly 6 includes a primary efficiency metal filter screen 601, an activated carbon filter cylinder 602, and a photocatalyst filter screen 603.

[0021] Specifically, the lower body 1 is provided with air inlets 12 on the left and right sides, and the upper body 2 is provided with an air outlet 13 on the top.

[0022] In this embodiment, after the purifier is connected to the power supply, the operation panel 7 is started, and under the action of the EC centrifugal fan 9, the old air is introduced from the air inlet 12, filtered and treated by the filter core assembly 6, and then discharged from the air outlet 13.

[0023] Specifically, the core cavity of the filter core assembly 6 is in communication with the through port 10, and the EC centrifugal fan 9 is located below the air outlet 13.

[0024] In the embodiment, the filter core assembly 6 is mainly composed of a primary efficiency metal filter screen 601, an activated carbon filter cartridge 602 and a photocatalyst filter screen 603. The primary efficiency metal filter screen 601 is usually the first line of defense in the filtration system and is mainly used to remove larger particles such as hair and coarse dust from the air. The activated carbon filter cartridge 602 is mainly used to adsorb odors and harmful gases in the air and provide a fresh and natural air environment. It effectively adsorbs harmful substances such as formaldehyde and pollen in the air through its porous structure and high specific surface area, thereby improving air quality. The photocatalyst filter screen 603 generates superoxide ion radicals, hydroxyl radicals and superoxide hydroxyl radicals with strong oxidation under the ultraviolet light irradiation of the UV lamp tube 11. These radicals not only oxidize and decompose toxic and harmful gases, pollutants, odors, bacteria and other harmful substances such as formaldehyde, benzene, toluene, xylene, ammonia and TVOC into harmless CO2 and H2O, but also have high-efficiency and broad-spectrum disinfection performance and can inhibit and kill various common pathogenic bacteria. The working principle of the EC centrifugal fan 9 is based on the centrifugal force principle. When the motor is started, the motor shaft drives the impeller to rotate at high speed, generating centrifugal force. This centrifugal force will accelerate the gas to form an airflow. The airflow enters the inlet of the centrifugal fan from the center of the impeller and is pushed to the outlet after being accelerated by the impeller, forming a certain pressure and flow rate.

[0025] Specifically, the bottom of the through hole 10 is attached to a sealing gasket 14, and the top surface of the filter core assembly 6 is tightly attached to the sealing gasket 14.

[0026] In the embodiment, the main function of the sealing gasket 14 is to provide sealing between two or more contact surfaces to prevent gas, liquid and dust from leaking through these contact surfaces.

[0027] Specifically, the bottom of the filter core support 5 is installed with telescopic springs 15, and the filter core support 5 is elastically installed in the lower body 1 through the telescopic springs 15.

[0028] In the embodiment, the telescopic springs 15 are used to provide a certain compensation for the installation of the filter core assembly 6, so that the filter core assembly 6 can be tightly attached to the sealing gasket 14, thereby ensuring the sealing performance of the filter core assembly 6 during installation.

[0029] Specifically, the lower part of the upper body 2 is provided with a power interface 16, and the power interface 16 is electrically connected to the operation panel 7 through wires.

[0030] In the embodiment, the main function of the power interface 16 is to transmit power signals to provide the required power support for the purifier.

[0031] In use, the lower body 1 and the upper body 2 are hingedly connected through a hinge, and are locked together through a flat lock 4, and are airtightly connected through a rectangular sealing ring 3, and the flat lock 4 is simple and efficient, and in the process of maintenance, the user only needs to rotate a key or operate a handle to easily open and close, and the filter element can be easily taken out from the lower body 1 for cleaning or replacement, which can save operation time and energy, and greatly facilitates the later maintenance work of the purifier.

[0032] In summary, the indoor photocatalyst formaldehyde removal device, the lower body 1 and the upper body 2 are hingedly connected through a hinge, and are locked together through a flat lock 4, and are airtightly connected through a rectangular sealing ring 3, and the flat lock 4 is simple and efficient, and in the process of maintenance, the user only needs to rotate a key or operate a handle to easily open and close, and the filter element can be easily taken out from the lower body 1 for cleaning or replacement, which can save operation time and energy, and greatly facilitates the later maintenance work of the purifier.
