[0035] It should be noted that in the embodiment, the two opposite end walls 113 can be the same square plate material, so that the end wall 113 and the side wall 115 can be assembled into a square columnar structure of the cabinet 11. In other embodiments, the two opposite end walls 113 can also be circular plate materials or special-shaped plate materials, and the two end walls 113 can be plate materials of the same shape and size or plate materials of different shapes and sizes, so that the end wall 113 and the side wall 115 can also be assembled into a cylindrical structure, a wedge-shaped columnar structure, a capsule-shaped structure, etc. of the cabinet 11.

[0036] Please refer to Figure 2 , Figure 3 and Figure 4 , wherein Figure 3 is Figure 1A perspective view of the high-voltage electrostatic module, Figure 4 For Figure 1 A schematic diagram of the air travel path in the high-voltage electrostatic module. The high-voltage electrostatic module 15 includes a housing 151 with a containing space, an ionization unit 153, and a dust collection unit 155. The containing space is connected to the first receiving chamber 117 through two oppositely arranged openings 1511, one of which corresponds to the air inlet 112, facilitating the air entering the containing space. The ionization unit 153 and the dust collection unit 155 are housed in the containing space and can be detachably fixed in the containing space. The ionization unit 153 is arranged close to the air inlet 112, and the dust collection unit 155 is arranged away from the air inlet 112. The ionization unit 153 and the dust collection unit 155 are arranged at intervals.

[0037] It should be noted that the housing 151 includes a plurality of detachable insulating plates that cooperate to form the containing space. In this embodiment, the outer surface of the housing 151 is provided with a plurality of threaded holes, and the high-voltage electrostatic module 15 can be fixed to the side wall 115 of the first receiving chamber 117 through the threaded holes using bolts. In other embodiments, the high-voltage electrostatic module 15 can also be fixed to the inner wall of the first receiving chamber 117 through insulating adhesive.

[0038] When maintaining the high-voltage electrostatic module 15, only the parts of the housing 151 need to be disassembled after complete power-off, and the ionization unit 153 and the dust collection unit 155 can be taken out for water cleaning. After drying, they can be reused. The maintenance process is simple and convenient, and the maintenance cost is low.

[0039] The ionization unit 153 includes a plurality of discharge electrodes 1531 and a plurality of ground electrodes 1533 arranged correspondingly. The discharge electrodes 1531 and the ground electrodes 1533 are alternately and spacedly arranged in a direction substantially perpendicular to the central axis of the opening 1511, and the air passes through the gap between the discharge electrodes 1531 and the ground electrodes 1533. The ground electrodes 1533 are grounded, and the discharge electrodes 1531 are electrically connected to the control module 13. The control module 13 controls the input voltage of the discharge electrodes 1531 to make the concentration of the byproduct ozone generated lower than the limited concentration of the national standard, which is harmless to human health.

[0040] When a specific voltage is applied, a high intensity non-uniform electric field is formed between the discharge electrode 1531 and the grounding electrode 1533, and corona discharge occurs when the air near the discharge electrode 1531 is broken down. The discharge electrode 1531 is a metal electrode with a sharp tip structure having a small radius of curvature. In this embodiment, the discharge electrode 1531 can be in a wire structure, and in other embodiments, the discharge electrode 1531 can also be in a mesh structure.

[0041] The dust collection unit 155 includes a plurality of high-voltage electrodes 1551 and a plurality of dust collection electrodes 1553 arranged correspondingly. The high-voltage electrodes 1551 and the dust collection electrodes 1553 are alternately and spacedly arranged along a direction substantially perpendicular to the central axis of the opening 1511, and the high-voltage electrodes 1551 and the dust collection electrodes 1553 are parallel to each other. The air passes through the gap between the high-voltage electrodes 1551 and the dust collection electrodes 1553. The high-voltage electrodes 1551 are electrically connected to the control module 13, and the dust collection electrodes 1553 are grounded.

[0042] When energized, a certain intensity of uniform electric field is formed between the high-voltage discharge electrode and the dust collection electrode 1553. The charged suspended particulate matter in the air is collected by the dust collection electrode 1553 under the action of the electric field force. In order to be in sufficient contact with the air, the high-voltage electrode 1551 and the dust collection electrode 1553 are both metal electrodes with a large surface area. In this embodiment, the high-voltage electrode 1551 and the dust collection electrode 1553 can be in a smooth plate structure, and in other embodiments, the high-voltage electrode 1551 and the dust collection electrode 1553 can also be in a fish scale plate structure.

[0043] Please refer to Figure 4 The working principle of the high-voltage electrostatic module 15 is as follows: the air enters the ionization unit 153, undergoes high-voltage corona discharge, and the gas molecules of the air are ionized to generate plasma. A large number of high-energy charged particles will adhere to the surface of the suspended particulate matter, and will have a breakdown etching effect on the bacteria or viruses in the aerosol, causing the cell membrane of the bacteria or viruses to be electroporated and lose its activity. After the air is ionized, it enters the dust collection unit 155. The surface-charged suspended particulate matter is self-settled due to the electrical attraction between them, and is further collected by the dust collection electrode 1553 through electrostatic attraction under the action of the external electric field force.

[0044] The ionization unit 153 and the dust collection unit 155 are spaced apart, and the high-voltage electrostatic module 15 separates and independently performs the charging process and the capture process of the suspended particulate matter in the air, which not only improves the dust removal efficiency, but also makes the electric field of the dust collection unit 155 uniform, which helps to control the deposition thickness of the suspended particulate matter collected on the surface of the dust collection electrode 1553, and effectively avoids the suspended particulate matter from flying due to the reverse corona phenomenon caused by the accumulation of electric charge on the surface of the dust collection electrode 1553.

[0045] Please refer to Figure 2 The photocatalytic module 17 includes a cooperating ultraviolet lamp group (not shown in the figure) and a photocatalytic filter screen (not shown in the figure), and the photocatalytic filter screen is arranged corresponding to the air vent 1111; the ultraviolet lamp group is electrically connected with the control unit, and the control unit adjusts the power of the ultraviolet lamp group to provide the photocatalytic filter screen with ultraviolet light of specific wavelength and specific intensity, which improves the photocatalytic reaction while avoiding the generation of harmful substance ozone. In this embodiment, the photocatalytic filter screen is provided with a plurality of threaded holes, and the photocatalytic module 17 is fixed to the baffle 111 by bolts. In other embodiments, the photocatalytic module 17 can also be fixed to the baffle 111 by an adhesive.

[0046] In this embodiment, the photocatalytic module 17 works based on the principle of total organic carbon photocatalytic reaction (TOC reaction), and the specific working process is as follows: the ultraviolet lamp group emits ultraviolet light, the photocatalytic filter screen is excited by ultraviolet light of a specific wavelength range (for example, short-wave ultraviolet light with a wavelength range of 252-256 nanometers), to generate free electrons and holes, and the generated free electrons and holes will react with water molecules and oxygen in the air to generate strong oxidizing free radicals, such as hydroxyl radicals and superoxide radicals; the strong oxidizing free radicals decompose volatile organic pollutants (VOC) in the air, such as formaldehyde, benzene, toluene, etc., to generate green and harmless carbon dioxide and water.

[0047] After the air in the first containing chamber 117 is subjected to dust removal and sterilization treatment, it can only enter the second containing chamber 119 through the air vent 1111 under the action of the air pressure difference due to the limitation of the baffle 111. Since the lifetime of free radical groups is usually very short, the diffusion distance in the gas phase is limited, so the concentration of free radicals near the photocatalytic module 17 is the highest; the arrangement of the baffle 111 and the air vent 1111 makes the air pass through the photocatalytic module 17 arranged corresponding to the air vent 1111 as much as possible, and fully contacts with the strong oxidizing free radicals and occurs decomposition reaction.

[0048] In the embodiment, the photocatalytic filter screen can be a nanometer titanium dioxide coated filter screen device. The ultraviolet lamp group can have a spectral peak wavelength of 254 nanometers. In other embodiments, the photocatalytic filter screen can also be other metal compound materials with good photocatalytic activity, such as tungsten oxide, tin oxide, or iron oxide, etc. The ultraviolet lamp group can also have a spectral peak wavelength of 185 nanometers, which can be selected according to actual design requirements.

[0049] Please refer to Figure 1 , Figure 5 and Figure 6 , wherein Figure 5 is a sectional view as shown in FIG. 1, Figure 1 is a perspective structural exploded view of the composite filter module 19 as shown in FIG. 2. The composite filter module 19 includes a plurality of adsorption beds 191 and adsorption filter materials 193. The adsorption beds 191 are sequentially connected end to end to form an adsorption carrier with a receiving cavity. The receiving cavity is in communication with the second receiving chamber 119 through an opening 197 and is in communication with the outside of the cabinet 11 through the air outlet 114. The adsorption filter materials 193 are arranged in the adsorption beds 191, and the adsorption surfaces of the adsorption filter materials 193 are arranged towards the receiving cavity. Figure 6 Figure 1 In the embodiment, the adsorption bed 191 is a single-layer flat plate structure with a hollow portion in the middle. The adsorption beds 191 are sequentially connected to form a square columnar adsorption carrier. The adsorption filter materials 193 can be embedded and fixed in the hollow portion of the adsorption bed 191. The adsorption carrier can be bonded and fixed to the corresponding end wall 113 of the second receiving chamber 119 by an adhesive. In other embodiments, the adsorption bed 191 can also be a single-layer arc-shaped plate structure or a single-layer wave-shaped plate structure. The adsorption filter materials 193 can also be bonded and fixed to the adsorption bed 191 by an adhesive. The adsorption carrier can also be fixed to the inner wall of the second receiving chamber 119 by bolts.

[0050] When the air passes through the receiving cavity from the air outlet 114, it can be further removed by adsorption and decomposition of the adsorption filter materials 193. The air conditioning terminal device 1 can process the air cooled, heated, or humidified to clean and harmless air, and improve the air supply quality of the air conditioning ventilation system. Since the air passing through the receiving cavity is not disturbed by any obstruction, the air resistance is low, which greatly reduces the energy consumption of the fan of the air conditioning ventilation system.

[0051]

[0052] ​​It can be understood that the adsorption filter material 193 is a porous material with adsorption performance, and the adsorption mechanism can be one or a combination of physical adsorption or chemical adsorption. In the present embodiment, the adsorption filter material 193 can be an activated carbon composite material, and in other embodiments, can also be a metal organic framework (MOFs) material, a bioceramic material, or a chemically modified zeolite, etc.
