[0028] Specifically, in the embodiment, the pre-filtering module 14, the high-voltage electrostatic module 15, the ozone removal module 16, the composite filtering module 17 and the ventilator 18 are sequentially arranged in the receiving space 11 along a preset direction, and the end portions of the pre-filtering module 14, the high-voltage electrostatic module 15, the ozone removal module 16, the composite filtering module 17 and the ventilator 18 located at one side of the preset direction are installed on the end wall of the cabinet 10.

[0029] The control module 12 controls the start and stop of the high-voltage electrostatic module 15 and the ventilator 18, and a pressure difference appears on both sides of the ventilator 18. The air outside enters the receiving space 11 under the action of negative pressure. The air travels along the travel route, first intercepts relatively large impurities such as fine hairs and the like by the pre-filtering module 14, is charged and collects suspended particulate matters in the air and kills microorganisms in the air by the high-voltage corona electric field of the high-voltage electrostatic module 15, and is treated by the adsorption and catalytic decomposition of the ozone removal module 16 and the composite filtering module 17 after the air is treated by the high-voltage electrostatic module 15, so as to obtain fresh air harmless to human body. The ventilator 18 discharges the fresh air from the receiving space 11 and accelerates the diffusion to the outside of the cabinet 10. In this way, the air purification device 1 completes the dust removal and purification and sterilization and disinfection treatment of the air.

[0030] Please refer to Figure 1 and Figure 2The cabinet 10 comprises a first baffle 101, two opposite end walls 103 and side walls connecting the end walls 103, which cooperatively form the accommodating space 11. In the embodiment, the side walls comprise a first face 105, a second face 106, a third face 107 and a fourth face 108, wherein the first face 105 is opposite to the third face 107, and the second face 106 is opposite to the fourth face 108. The first baffle 101 is located in the accommodating space 11, adjacent to the second face 106 of the side wall and substantially parallel to the second face 106.

[0031] It should be noted that, in the embodiment, the first face 105, the second face 106, the third face 107 and the fourth face 108 can be directly connected in sequence, and the side walls and the end walls 103 can cooperatively form the cabinet 10 in a square columnar structure; and the second face 106 and the third face 107 can be connected by a hinge connection mechanism, so that the second face 106 can rotate relative to the third face 107 to facilitate maintenance or replacement of components accommodated in the accommodating space 11.

[0033] The cabinet 10 further comprises an air inlet 1051 arranged on the side wall and corresponding to the high-voltage electrostatic module 15. In the embodiment, the air inlet 1051 is arranged on the first face 105 of the side wall. External air will enter the accommodating space 11 from the air inlet 1051 under the action of negative pressure. The direction of the air, i.e. the direction from the first face 105 to the second face 106, is the preset direction, along which the pre-filter module 14, the high-voltage electrostatic module 15, the ozone removal module 16, the composite filter module 17 and the ventilator 18 are arranged in sequence.

[0034] The cabinet 10 further comprises a second baffle 109. The second baffle 109 is located in the receiving space 11, and one end of the second baffle 109 is fixedly connected to the first surface 105, and the opposite end extends in the receiving space 11 along the preset direction. The opposite ends of the high-voltage electrostatic module 15 are respectively fixed to any one of the end wall 103 and the second baffle 109. The sizes of the pre-filter module 14, the ozone removal module 16, and the composite filter module 17 are matched with the high-voltage electrostatic module 15, so that the opposite ends of the pre-filter module 14, the ozone removal module 16, and the composite filter module 17 are respectively fixed to the end wall 103 and the second baffle 109 in the same way.

[0035] The air duct part of the ventilator 18 corresponds to the high-voltage electrostatic module 15. A third baffle 181 is arranged between the air duct part and the motor part of the ventilator 18. One end of the air duct part of the ventilator 18 is fixed to the end wall 103, and the opposite end is fixed to the third surface 107 of the side wall through the third baffle 181.

[0036] The second baffle 109 and the third baffle 181 cooperate to divide the receiving space 11 into a first working area and a second working area.

[0037] The cabinet 10 further comprises air outlets 1011. The air outlets 1011 are arranged on the side wall corresponding to the air duct part of the ventilator 18. In this embodiment, the number of air outlets 1011 is two, and the air outlets 1011 are arranged on the second surface 106 of the side wall and the first baffle 101 arranged adjacent to the second surface 106.

The number of air outlets 1011 is at least one.

[0038] The first baffle 101, the second baffle 109 and the third baffle 181 cooperate with the side wall and the end wall 103 of the cabinet 10, so that the first working area and the second working area are independent of each other and do not interfere with each other, avoiding the overflow of untreated air, and ensuring the processing conversion rate and processing efficiency. Under the protection of the first baffle 101, the high-voltage power supply 13, the control module 12 and the interaction module 19 can be individually maintained or debugged and upgraded, further ensuring the safety of maintenance personnel when the air purification device 1 is continuously powered on for debugging.

[0039] Please refer to Figure 2 and Figure 4 , wherein Figure 4 is Figure 2 the schematic diagram of the air travel path in the high-voltage electrostatic module. The high-voltage electrostatic module 15 includes a shell 155, an ionization unit 151 and a dust collection unit 153. The shell 155 has a receiving cavity which is communicated to the receiving space 11 through two opposite openings, one of which is directed to the pre-filtering module 14 and the other is directed to the ozone removal module 16. The ionization unit 151 and the dust collection unit 153 are received in the receiving cavity and are spaced apart along the preset direction.

[0040] The ionization unit 151 includes a plurality of discharge electrodes 1511 and a plurality of ground electrodes 1513 arranged correspondingly. The discharge electrodes 1511 and the ground electrodes 1513 are alternately and spaced apart along a direction perpendicular to the preset direction, and the air passes through the gap between the discharge electrodes 1511 and the ground electrodes 1513 under the action of negative pressure.

[0041] After being powered on, a high-intensity non-uniform electric field is formed between the discharge electrodes 1511 and the ground electrodes 1513, and corona discharge occurs when the air near the discharge electrodes 1511 is broken down. The discharge electrodes 1511 are metal electrodes with a sharp tip structure having a small radius of curvature. In the present embodiment, the discharge electrodes 1511 can be in a wire structure, and in other embodiments, the discharge electrodes 1511 can also be in a mesh structure.

[0042] The dust collection unit 153 includes a plurality of high-voltage electrodes 1531 and a plurality of dust collection electrodes 1533 arranged correspondingly. The high-voltage electrodes 1511 and the dust collection electrodes 1533 are alternately and spaced apart along a direction perpendicular to the preset direction and parallel to each other, and the air passes through the gap between the high-voltage electrodes 1531 and the dust collection electrodes 1533 under the action of negative pressure. The high-voltage electrodes 1531 are electrically connected to the control module 12, and the dust collection electrodes 1533 are grounded.

[0043] After being energized, a uniform electric field of a certain intensity is formed between the high-voltage discharge electrode 1511 and the dust collection electrode 1533. Charged suspended particles in the air are collected by the dust collection electrode 1533 under the influence of the electric field. To ensure sufficient contact with the air, both the high-voltage discharge electrode 1511 and the dust collection electrode 1533 are metal electrodes with a large surface area. In this embodiment, the high-voltage discharge electrode 1511 and the dust collection electrode 1533 can be smooth plate structures. In other embodiments, the high-voltage discharge electrode 1511 and the dust collection electrode 1533 can also be fish-scale plate structures.

[0044] The working principle of the high-voltage electrostatic module is as follows: The air first enters the ionization unit 151, and after high-voltage corona discharge, the gas molecules of the air are ionized to generate plasma. A large number of high-energy charged particles in the plasma adhere to the surface of suspended particulate matter and undergo a breakdown etching effect with bacteria or viruses in the aerosol. The cell membranes of bacteria or viruses are electroporated, causing them to lose their activity. The ozone and nitrogen oxides in the by-reaction products of high-voltage discharge also have strong oxidizing capabilities, further ensuring the killing effect of bacteria or viruses in the air. After being ionized, the air enters the dust collection unit 153. The suspended particulate matter with charged surfaces settles due to electrostatic attraction. Under the action of an external electric field, it is further collected by the dust collection electrode 1533 through electrostatic attraction.

[0045] It should be noted that the outer casing 155 includes multiple detachably connected insulating plates, which cooperate to form the receiving cavity. In this embodiment, the outer surface of the outer casing 155 is provided with multiple threaded holes, through which the high-voltage electrostatic module 15 can be fixed to the end wall 103 and the second baffle 109 using bolts. In other embodiments, the high-voltage electrostatic module 15 can also be fixed to the end wall 103 and the second baffle 109 by adhesive bonding.

[0046] The advantage of the ionization unit 151 and the dust collection unit 153 being spaced apart is that the high-voltage electrostatic module 15 separates and independently performs the charging process and collection process of the suspended particles in the air. This not only improves the dust removal efficiency, but also makes the electric field distribution of the dust collection unit 153 uniform, which helps to control the deposition thickness of the suspended particles collected on the surface of the dust collection electrode 1533. This effectively avoids the back corona phenomenon caused by the accumulation of charge on the surface of the dust collection electrode 1533, which causes the deposited suspended particles to fly away.

[0047] When maintaining the high-voltage electrostatic module 15, it is only necessary to remove part of the insulating plate of the outer shell 155 after completely disconnecting the power. Then, the ionization unit 151 and the dust collection unit 153 can be taken out for washing and cleaning, and then dried for reuse. The maintenance process is simple and convenient, and the maintenance cost is low.

[0048] Please see Figure 2 The ozone removal module 16 is disposed adjacent to the dust collection unit 153 of the high-voltage electrostatic module 15. In this embodiment, the housing of the ozone removal module 16 has several threaded holes at opposite ends for fixing to the end wall 103 and the second baffle 109 by bolts, respectively. In other embodiments, the ozone removal module 16 can also be fixed to the end wall 103 and the second baffle 109 by adhesive bonding.

[0049] The ozone removal module 16 is an ozone catalytic decomposition filter including a metal catalyst. Through the catalysis of the metal catalyst, the ozone, a reaction byproduct of the high-voltage electrostatic module 15, is decomposed into oxygen to provide safe and harmless clean air. In this embodiment, the ozone removal module 16 can be an ozone catalytic decomposition filter including copper oxide. In other embodiments, the ozone removal module 16 can also be an ozone catalytic decomposition filter including activated carbon and manganese oxide.

[0050] Please see Figure 2 The pre-filter module 14 is arranged adjacent to the ionization unit 151 of the high-voltage electrostatic module 15. The air entering from the air inlet 1051 is pre-filtered by the pre-filter module 14 before entering the ionization unit 151, thereby improving the charging efficiency of the ionization unit 151.

[0051] The pre-filtration module 14 is a filter comprising a filter screen and a support body for fixing and supporting the filter screen. In this embodiment, the pre-filtration module 14 can be a filter in which a metal filter screen is supported by a plastic frame, and the plastic frame has several threaded holes at opposite ends for fixing to the end wall 103 and the second baffle 109 by bolts, respectively. In other embodiments, the pre-filtration module 14 can also be a filter in which a polyester fiber filter screen is supported by an aluminum alloy frame, and the opposite ends of the pre-filtration module 14 can also be fixed to the end wall 103 and the second baffle 109 by adhesive bonding.

[0052] When maintaining the pre-filter module 14, it is only necessary to wash and clean the pre-filter module 14 with water and then dry it for repeated use. The pre-filter module 14 is easy to maintain and has a long service life.

[0053] Please see Figure 2The ventilator 18 is an air pressurization device comprising a motor, a duct wall, and an impeller. One end of the duct wall is the air inlet, and the opposite end is the air outlet. The air inlet faces the air inlet 1051, and the air outlet faces the air outlet 1011. The impeller uses centrifugal force to accelerate the treated air out of the casing 10 through the air outlet 1011. The motor is electrically connected to the control module 12 via any conductive material. The control module 12 controls the start and stop of the ventilator 18 by powering on or off, and controls the impeller speed of the ventilator 18 by adjusting the power supply. In this embodiment, the ventilator 18 can be a round straight-blade crossflow fan; in other embodiments, it can also be an airfoil crossflow fan.

[0054] Please see Figure 2 The composite filter module 17 is located between the ozone removal module 16 and the ventilator 18. In this embodiment, the outer shell of the composite filter module 17 has several threaded holes at both opposite ends for fixing to the end wall 103 and the second baffle 109 by bolts, respectively. In other embodiments, the composite filter module 17 can also be fixed to the end wall 103 and the second baffle 109 by adhesive bonding.

[0055] The composite filtration module 17 is a composite catalytic decomposition filter comprising an adsorption bed and multiple layers of different catalysts. It is used to adsorb harmful gaseous pollutants such as nitrogen oxides, formaldehyde, benzene, and toluene from the air, ensuring thorough air purification at room temperature without posing a safety hazard to humans. In this embodiment, the composite filtration module 17 can be a composite catalytic decomposition filter comprising an activated carbon adsorption bed, titanium dioxide photocatalyst, copper oxide catalyst, and precious metals supported by molecular sieves. For example, the molecular sieve can be SSZ-molecular sieve, and the precious metal can be platinum. In other embodiments, the composite filtration module 17 can also be a composite catalytic decomposition filter comprising a diatomaceous earth adsorption bed, manganese oxide catalyst, and precious metals supported by nano-titanium dioxide. For example, the precious metal can be platinum.

[0056] Please refer to the following: Figure 2 and Figure 3 ,in Figure 3 for Figure 1The diagram shows a plan view of the air purifier. The interaction module 19 is disposed on the second surface 106 of the sidewall, partially housed in the housing space 11, and partially exposed on the outer surface of the chassis 10. The interaction module 19 includes several status indicator lights 191, several operating parts 193, and sensors corresponding to the operating parts 193. The status indicator lights 191 and the sensors are electrically connected to the control module 12 via any conductor. Both the status indicator lights 191 and the operating parts 193 are exposed on the exterior of the chassis 10 for user viewing or operation. The sensors convert non-electrical signals generated by the user's interaction with the operating parts 193 into electrical signals and transmit them to the control module 12. The control module 12 sends commands to the status indicator lights 191 to keep them constantly lit, flashing, or turned off.

[0057] The status indicator lights 191 are respectively labeled with text on the outer surface of the housing 10. In this embodiment, there can be six status indicator lights 191, which are labeled with "Working", "Replacement", "Filter", "Low Fan Speed", "Medium Fan Speed", and "High Fan Speed". In other embodiments, the number of status indicator lights 191 can be increased or decreased according to actual design requirements, and the text labels corresponding to the status indicator lights 191 can be adaptively adjusted in terms of text content or language so that the user of the air purifier 1 can clearly understand their meaning.

[0058] It should be noted that the interaction module 19 can also communicate wirelessly with other human-computer interaction terminal devices, such as operator consoles, personal mobile devices, home intelligent management systems, etc. Users can indirectly input interactive commands to the interaction module 19 through other interactive terminal devices, or directly input interactive actions to the interaction module 19 by touching or pressing the operation part 193. In this embodiment, the sensor can be a pressure sensor; in other embodiments, the sensor can also be an optical sensor or a capacitive sensor, etc.

[0059] The air purification device 1 further includes a first working mode, a second working mode, a third working mode, and a maintenance mode. In the first working mode, the second working mode, or the third working mode, the control module 12 controls the high-voltage electrostatic module 15 and the fan 18 to start working. Depending on the working mode, the air purification device 1 provides different air speeds to adapt to the needs of different usage scenarios. In this embodiment, the impeller speed of the fan 18 can be 1800 revolutions per minute in the first working mode, 1400 revolutions per minute in the second working mode, and 1000 revolutions per minute in the third working mode. In other embodiments, the number of working modes can be increased or decreased according to actual design requirements, and the preset speed parameters of the fan 18 in different working modes can be adjusted accordingly. For example, in the silent working mode, a low speed of 500 revolutions per minute can be set for the fan 18 to improve the user experience.

[0060] The maintenance modes include a maintenance and replacement mode and a maintenance operation mode. In the maintenance operation mode, the control module 12 controls the high-voltage electrostatic module 15 and the fan 18 to operate normally, and simultaneously sends a command to the status indicator light 191 to flash according to a preset cycle, reminding the user to maintain and clean the air purifier 1. In the maintenance and replacement mode, the control module 12 cuts off the power supply to the high-voltage electrostatic module 15 and the fan 18, facilitating the user to maintain, clean, or replace the various modules of the air purifier 1.
