[0022] Reference Figure 1The embodiment of the present invention provides an air purification device with static electricity, which is mainly composed of a housing 1, an electrostatic generator, a plurality of felt plates 4, a negative ion membrane and a driving module. The housing 1 is provided with an air inlet and an air outlet, and the housing 1 is arranged in a cylindrical shape, one end of which is arranged as an air inlet, and the other end is arranged as an air outlet. The electrostatic generator is arranged in the housing 1, and the electrostatic generator is fixed to the middle part of the housing 1 by arranging a support frame. The electrostatic generator is used to generate an electrostatic field in the housing 1, and a plurality of the felt plates 4 are arranged on the inner side of the housing 1 and the outer side of the electrostatic generator. The plurality of the felt plates 4 are arranged at intervals to form a guide channel, and the driving module drives the air to flow from the air inlet to the air outlet, so that the air must pass through the guide channel composed of a plurality of felt plates 4 when flowing from the air inlet to the air outlet, and the felt plates 4 are in the electrostatic field in the housing 1. The negative ion membrane is arranged on a plurality of felt plates 4, and the negative ion membrane is used to generate negative ions. The electrostatically charged air purification device can generate an electrostatic field in the shell 1 through an electrostatic generator, so that the felt board 4 arranged in the shell 1 has static electricity. When the driving module drives the air to flow toward the air outlet, the negative ion membrane continuously generates negative ions to cause dust to aggregate. The air with oil or dust will collide with the felt board 4 of the guide channel. The oil or dust in the air will be retained on the statically charged felt board 4 through the electrostatic effect, thereby comprehensively purifying the air.

[0023] Preferably, the electrostatic generator includes an electrostatic generating chamber 301, a first impeller 302, a transmission shaft and a brush 303. The electrostatic generating chamber 301 is provided with an electrostatic generating cavity. The transmission shaft is passed through the electrostatic generating chamber 301, that is, part of the transmission shaft is located in the electrostatic generating cavity, and part of the transmission shaft is located outside the electrostatic generating chamber 301. The first impeller 302 is fixed on the transmission shaft outside the electrostatic generating chamber 301, and the brush 303 is fixed on the transmission shaft inside the electrostatic generating chamber 301. The first impeller 302 drives the brush 303 to rotate through the transmission shaft to generate static electricity. Specifically, the outer wall of the electrostatic generating chamber 301 is made of metal. The static electricity generated in the electrostatic generating chamber 301 can be conducted to the outer shell 1 through the metal outer wall, so that the multiple felt boards 4 in the outer shell 1 are all attached with static electricity. Static electricity is generated by friction between the brush 303 and the outer wall of the static electricity generating chamber 301, and the brush 303 is driven to rotate by the first impeller 302. The structure is simple and the manufacturing cost is low. The first impeller 302 can be driven by natural wind from the outside and can be used in most places.

[0024] Preferably, the driving module is arranged on the housing 1 at the air outlet end, and the driving module comprises a centrifugal fan 201 and a second impeller 202, wherein the second impeller 202 is arranged on the driving shaft of the centrifugal fan 201, and the centrifugal fan 201 drives the second impeller 202 to rotate. The driving module is arranged at one end of the air outlet, and the centrifugal fan 201 generates suction force, which can drive air to flow from the air inlet to the air outlet.

[0025] Preferably, the felt plate 4 is carbon felt, which has a highly developed microporous structure, large adsorption capacity, fast desorption speed, good purification effect, heat resistance, acid resistance, alkali resistance and other characteristics, and has good adsorption properties for gasoline, aldehydes, phenols, alcohols, olefins and other organic vapors and inorganic gases.

[0026] Preferably, the electrostatically charged air purification device further comprises activated carbon, and the activated carbon is arranged on the surface of the carbon felt.

[0027] Preferably, the electrostatically charged air purification device further comprises an ion membrane, which is arranged on the surface of the carbon felt. The ion membrane has cation selective permeability and can improve the air purification effect.

[0028] Preferably, the electrostatically charged air purification device further comprises a dust collecting plate 5 which is concave toward the inner side of the housing 1, and the air inlet is arranged at the center of the dust collecting plate 5, and the aperture of the air inlet gradually decreases from the periphery to the center. After the air enters from the air inlet located at the center of the dust collecting plate 5, it enters the guide channel located outside the electrostatic generating chamber 301, and collides with the felt plate 4 in the guide channel, so that impurities such as dust in the air fall into the dust collecting plate 5. The dust collecting plate 5 is provided with a slope, so that the dust is deposited at the bottom of the dust collecting plate 5, which is convenient for collecting and cleaning the dust.

[0029] Preferably, a plurality of the felt plates 4 are stacked and alternately arranged on the inner side of the housing 1 and the outer side of the electrostatic generator, and the plurality of the felt plates 4, the inner side of the housing 1 and the outer side of the electrostatic generator form a guide channel that bends back and forth, and the outlet of the guide channel is aligned with the air outlet. Specifically, the inlet of the guide channel is close to the inner wall of the housing 1, and is correspondingly arranged above the dust collecting tray 5, so that dust in the air can accurately fall into the dust collecting tray 5 when it falls, and dust is prevented from floating out of the air inlet. The guide channel is arranged to bend back and forth, which can maximize the length of the guide channel, increase the contact area between the air and the felt plates 4, and thus improve the air purification effect. The outlet of the guide channel is arranged below the corresponding position of the air outlet, so that the purified air can flow out of the air purification device.
