Decoration pollution has also become an important source of pollution in residents' lives, and air purifiers have become more and more popular. An air purifier is a device that can adsorb, decompose or transform various air pollutants (generally including decoration pollution such as dust, pollen, odor, formaldehyde, bacteria, allergens, etc.), which can effectively improve the cleanliness of the air. However, existing air purification devices generally capture particles through the following four methods: direct interception, inertial collision, Brownian diffusion mechanism, and screening effect. It has a good collection effect on fine particles, but when there are larger dust particles, this air purification device has no dust removal and dust collection device, and directly uses the filter to purify the air, which reduces the life of the filter, which undoubtedly causes waste. Therefore, a new technical solution is needed to solve this problem. Summary of the invention

A second filter screen 8 is fixedly arranged on the right side of the dust removal duct 7, and a third filter screen 9 is fixedly arranged on the right side of the second filter screen 8. The third filter screen 9 is fixedly connected to the inner wall of the outer shell 1. A transformer 10 and a rectifier 11 are fixedly connected to the inner wall of the outer shell 1. The transformer 10 and the rectifier 11 are electrically connected. An air intake grille is opened on the left side of the outer shell 1, and an exhaust grille is opened on the right side of the outer shell 1. The outer shell 1, the fan blade cover 3 and the fan blades are all made of plastic, and the air inlet duct 4, the ionization duct 6 and the dust removal duct 7 are all made of polypropylene.

[0022] refer to Figure 1 and Figure 2 The connections between the first filter screen 2, the fan cover 3, the air inlet duct 4, the ionization duct 6, the dust removal duct 7, the second filter screen 8 and the third filter screen 9 are all sealed. The sealed duct prevents unpurified air from entering the duct. The air inlet duct 4, the ionization duct 6 and the dust removal duct 7 are all fixedly provided with sealing rubber rings. Since there is high voltage in the ionization duct 6 and the dust removal duct 7, the use of insulating materials can improve safety.

[0023] refer to Figure 1 and Figure 2 Two first electrodes 601 are fixedly connected to the inner wall of the ionization tube 6. The two first electrodes 601 are symmetrically arranged on the inner wall of the ionization tube 6. The two first electrodes 601 have opposite electrical properties. In this embodiment, the first electrode 601 with positive electrical property is cylindrical, and the first electrode 601 with negative electrical property is plate-shaped.

[0024] refer to Figure 1 and Figure 2A second electrode 701 is fixedly connected to the upper inner wall of the dust removal pipe 7, and a third electrode 702 is slidably connected to the lower inner wall of the dust removal pipe 7. The longitudinal sections of the second electrode 701 and the third electrode 702 are semicircular. A bracket 703 is fixedly arranged on the third electrode 702, and a dust collecting rod 704 is slidably connected in the bracket 703. When the power is disconnected, the third electrode 702 can act as an integrated board, and dust will fall onto the third electrode 702. In this embodiment, pull rods are provided at the left ends of the third electrode 702 and the dust collecting rod 704 to facilitate the removal of the third electrode 702 and the dust collecting rod 704. The second electrode 701 and the third electrode 702 are negative electrodes, and the dust collecting rod 704 is positive. The electric potentials of the second electrode 701 and the third electrode 702 are equal, and a potential difference is generated among the second electrode 701, the third electrode 702 and the dust collecting rod 704. When dust passes by, the dust will be adsorbed on the dust collecting rod 704.

[0025] refer to Figure 1 The first filter 2 is a primary filter, the second filter 8 is an ozone filter, and the third filter 9 is a HEPA filter. The primary filter performs preliminary filtration. Since ozone may be produced during the electrolysis process, the ozone filter is configured to filter ozone, and the HEPA filter further purifies the air.

[0027] To sum up, when the present invention is used, the power is turned on, the motor 5 starts to work, the air enters the first filter 2 from the air intake grille, and is simply filtered. The air enters the ionization pipe 6 through the air inlet duct 4. The two first electrodes 601 have opposite electrical properties. The air is ionized in the ionization pipe 6 so that the dust is negatively charged. The ionized air enters the dust removal pipe 7. The second electrode 701 and the third electrode 702 are negative electrodes, and the dust collecting rod 704 is positive. The potentials of the second electrode 701 and the third electrode 702 are equal. The second electrode 701, the third electrode 702 and the dust collecting rod 704 generate a potential difference. When the dust with negative charge passes through, the dust will be adsorbed on the dust collecting rod 704. The air after dust removal is further filtered through the second filter 8 and the third filter 9, and clean air is discharged. When cleaning the dust, disconnect the power supply, open the sealing cover 12, take out the third electrode 702 and the dust collecting rod 704, and clean it directly. The operation is simple, convenient and fast.
