[0028] The present invention will be further described below with reference to the accompanying drawings and specific embodiments.

[0029] See Figure 1 , shows a schematic structural diagram of an air purification device of the present invention. The present invention provides an air purification device, comprising: a base 1, on which a receiving groove 101 is provided.

[0030] The shapes and dimensions of the base 1 and the receiving groove 101 are determined according to actual needs and are not specifically limited herein.

[0031] The housing 2 is disposed on the base 1 , and a receiving space 201 is defined inside the housing 2 .

[0032] The housing 2 is placed directly above the receiving groove 101 .

[0033] In this embodiment, the housing 2 is configured to be in the shape of a rectangular box. In other embodiments, the housing 2 may also be in the shape of a drum box, which is configured according to actual needs and is not specifically limited here.

[0034] The water tank 3 is arranged at the upper end of the shell 2.

[0035] Wherein, the upper end of the water tank 3 is provided with a water inlet, which can be blocked with a rubber stopper 301. Before the device is used, the rubber stopper at the water inlet needs to be opened to input a sufficient amount of water into the water tank 3.

[0036] The filter assembly 4 is arranged on the side wall of the housing 2 to filter the air flowing through.

[0037] The number and location of the filter components 4 are set according to actual needs and are not specifically limited here. The specific structure of the filter components 4 is described in detail below and will not be repeated here.

[0038] The flushing component 5 is arranged in the accommodating space 201 of the shell 2. The flushing component 5 is connected to the water tank 3 and can flush the filter component 4.

[0039] Among them, the setting position of the flushing component 5 corresponds to the position of the filtering component 4, and the setting number of the flushing component 5 corresponds to the number of the filtering components 4. The specific structure of the flushing component 5 is described in detail below and will not be repeated here.

[0040] The recovery component 6 is arranged in the accommodating tank 101 below the outer shell 2. The recovery component 6 can extend into the accommodating space 201 to collect the mixed water generated by flushing and filter it to obtain clean water. The recovery component 6 is connected to the water tank 3 and can input the clean water into the water tank 3.

[0041] The specific structure of the recycling component 6 is described in detail below and will not be repeated here.

[0042] See Figure 2 and Figure 3 , Figure 2 shows a cross-sectional view of the housing of the present invention, Figure 3 The present invention provides an air purification device, wherein the filter assembly 4 comprises a filter plate 401 , which is arranged on the side wall of the housing 2 and has a plurality of first filter holes.

[0043] The filter plate 401 is arranged along the side wall of the housing 2 , and air enters the accommodating space 201 through the first filter holes on the filter plate 401 .

[0044] In this embodiment, an activated carbon layer is provided on the filter plate 401, which can intercept dust particles of different particle sizes and absorb harmful gases such as formaldehyde.

[0045] The fan blades 402 are arranged on the inner wall of the filter plate 401 .

[0046] The rotation of the fan blades 402 accelerates the air flow at the filter plate 401 .

[0047] In this embodiment, the fan blades are brushless fan blades 402. The brushless fan blades 402 have no brush friction, so the noise during operation is low, and the brushless fan blades 402 do not generate sparks, reducing the risk of fire. They are more reliable in long-term operation and harsh environments, and have a longer service life.

[0048] The filter cartridge 403 has a port connected to the filter plate 401 , and the filter cartridge 403 is covered on the outer periphery of the fan blade 402 . The filter cartridge 403 is provided with a plurality of second filter holes.

[0066] Multiple water nozzles 509 are arranged at intervals along the inner ring wall of the annular water pipe 508.

[0067] A plurality of water spray heads 509 are arranged around the inner wall of the annular water pipe 508. The number and spacing of the water spray heads 509 are determined based on actual needs and are not specifically limited herein.

[0068] In this embodiment, since the annular water pipe 508 is movable in the transverse direction, it drives the water nozzle 509 to move, thereby achieving the effect of fully flushing the filter cartridge 403 and effectively preventing it from being blocked.

[0069] In this embodiment, corresponding to the four filter assemblies 4 on the four side walls of the housing 2 , four flushing assemblies 5 are provided in the accommodating space 201 , respectively corresponding to the filter cartridges 403 of the flushing filter assemblies 4 .
