[0025] The technical solutions provided by the embodiments of the present invention will be described in detail below in conjunction with the accompanying drawings.

[0026] Embodiment 1

[0027] As Figures 1 to 3 shown, the air purification component at the air inlet of the air conditioner in this Embodiment 1 is detachably installed at the air inlet of the air conditioner 200 and used in cooperation with the air conditioner 200. The air purification component 100 includes a housing 10, a first filter component 20, and a second filter component 30. The housing 10 is provided with an air inlet, an air outlet, and a duct provided between the air inlet and the air outlet. The first filter component 20 and the second filter component 30 are installed in the duct. The first filter component 20 includes a light source and a first primary filter screen 21, a first secondary filter screen 22, a first biological filter screen 23, a first light barrier filter screen 24, and a first photocatalyst filter screen 25 arranged in sequence along the air flow direction. The first biological filter screen 23 is used to filter bacteria in the flowing air, and the first light barrier filter screen 24 is used to allow air to pass through while blocking light. The light source is used to provide light for the first photocatalyst filter screen 25. The second filter component 30 includes a second photocatalyst filter screen, a second light barrier filter screen, a second biological filter screen, a second secondary filter screen, and a second primary filter screen arranged in sequence along the air flow direction. The second photocatalyst filter screen is arranged on the air outlet side of the first photocatalyst filter screen 25. The air flow discharged from the air outlet of the air purification component 100 enters the air conditioner 200.

[0028] In practical applications, as Figure 1 shown, the air purification component 100 is installed on the inlet side grille of the air conditioner 200 so that the air purification component 100 can be used in cooperation with the air conditioner 200. When the air conditioner 200 is started for refrigeration, indoor air enters from the air inlet of the air purification component 100. The first primary filter screen 21 filters large particulate pollutants such as dust and hair in the air flow, achieving a preliminary physical interception effect on the air flow. Subsequently, the air flow passes through the first secondary filter screen 22, and the first secondary filter screen 22 filters fine particulate matters such as PM2.5 and some bacteria in the air flow, aiming to achieve a further physical interception effect on the air flow. Then the air flow passes through the first biological filter screen 23, and the first biological filter screen 23 further filters bacteria in the air flow. Then the air flow passes through the first light barrier filter screen 24 and reaches the first photocatalyst filter screen 25. Under the irradiation of the light source in the air purification component 100, the first photocatalyst filter screen 25 can decompose chemical pollution gases such as formaldehyde, achieving the effect of disinfecting the air flow.

[0029] Among them, the first light barrier filter screen 24 has the characteristics of being breathable and light-impermeable, and is used to block and partially reflect the light emitted by the arc light source, preventing the first biological filter screen 23 from being affected by the light source irradiation and thus affecting its filtering performance.

[0030] Finally, the air flow is discharged from the air outlet of the air purification component 100 and enters the air conditioner 200. Thus, the air flow on the air inlet side of the air conditioner 200 is filtered for particulate matter and sterilized (such as killing fungi such as Aspergillus flavus and viruses such as H1N1), so as to achieve the purpose of improving the indoor air quality.

[0031] In addition, since the air purification component 100 involved in this Embodiment 1 is used in conjunction with the air conditioner 200, there is no need to separately purchase and use a relatively more energy-consuming air purifier on the market, thus achieving the purpose of reducing economic costs.

[0032] In this Embodiment 1, the light source is arranged on the air outlet side of the first photocatalyst filter screen 25, so that the first photocatalyst filter screen 25 can be fully irradiated by the light source, thereby achieving the disinfection effect of decomposing chemical pollution gases such as formaldehyde.

[0033] In other embodiments, the light source can also be arranged at other positions on the air outlet side of the first light blocking layer filter screen 24 in the air purification component 100, such as the air inlet side of the first photocatalyst filter screen 25, etc. So that while the light source irradiates the first photocatalyst filter screen 25, the light emitted by the light source will be blocked and partially reflected by the first light blocking layer filter screen 24, so that the first biological filter screen 23 will not be affected by the light source irradiation and its own performance will not be affected.

[0034] Furthermore, as Figure 2 shown, the air purification component 100 further includes a fan 40. Specifically, the fan 40 is arranged on the air outlet side of the first photocatalyst filter screen 25 to drive the air to flow in and be pressurized and sent out, overcoming the resistance generated by the purification device to the air flow on the air inlet side of the air conditioner 200, increasing the air pressure at the air inlet of the air conditioner 200, and thus increasing the air pressure at the air outlet of the air conditioner 200, which has a promoting effect on the jet range of the air outlet of the air conditioner 200.

[0035] In other embodiments, the fan 40 can also be arranged on the air inlet side of the first primary filter screen 21 in the air purification component 100, or between two adjacent filter screens, and the same effect of driving the air flow and increasing the air pressure at the air inlet of the indoor air conditioner can be achieved.

[0036] Preferably, the fan 40 is a centrifugal fan 40. Specifically, a DC variable frequency centrifugal fan or an AC constant speed centrifugal fan can be used. In addition, a swirl vane is provided at the air outlet of the fan 40 to achieve the effect of swirl pressurized air supply, increasing the air pressure at the air outlet of the air conditioner 200, and having a certain promoting effect on the jet range of the air supply, making the air flow passing through the air purification component 100 and sent out by the air conditioner 200 more in line with the human body's thermal comfort requirements.

[0037] At this time, as Figure 2As shown, the air purification component 100 further includes a housing 10. Air enters the air purification component 100 from the air inlet of the housing 10. After passing through the functions of filtering particulate matter, sterilizing, and disinfecting by the first filter component 20, it leaves the air purification component 100 from the air outlet of the housing 10, and then enters the air inlet side of the air conditioner 200.

[0038] As Figure 3 As shown, the first primary filter screen 21 in the air purification component 100 is a primary filter screen, which is used to filter large particulate pollutants such as dust and hair in the air flow, so as to achieve the initial physical interception effect on the air flow. In this Embodiment 1, the first primary filter screen 21 is made of a filter screen made of fiber carbon cloth; in other embodiments, the material of the first primary filter screen 21 can also be made of other materials such as carbon layer fiber cloth, carbon crystal layer fiber cloth, and graphene fiber cloth.

[0039] And, the first secondary filter screen 22 is a HEPA filter screen, which is used to filter PM2.5 and other fine particulate matters and some bacteria in the air flow, and its purpose is to achieve a further physical interception effect on the air flow. Specifically, the first secondary filter screen 22 is made of a filter screen made of non-woven fabric.

[0040] At the same time, the first biological filter screen 23 is a lysozyme filter screen, and its function is to use lysozyme to destroy the cell wall of bacteria to kill some bacteria, so as to achieve the effect of further filtering bacteria in the air flow. Among them, the preparation of lysozyme uses a novel ionic liquid [C4MIM]3CB modified by CB to extract lysozyme from egg white.

[0041] Specifically, the light source is an ultraviolet lamp. With the cooperation of the ultraviolet lamp, the first photocatalyst filter screen 25 can decompose chemical pollution gases such as formaldehyde, so as to achieve the effect of disinfecting the air flow. Among them, the photocatalyst is derived from a titanium dioxide transparent photocatalyst emulsion doped with metal ion europium prepared by a room temperature complexation-controlled hydrolysis method. In addition, the ultraviolet lamp also has the function of directly killing some bacteria and viruses. The light source uses an ultraviolet lamp that emits ultraviolet light in the wavelength range of 250nm to 370nm. The ultraviolet lamp used in this Embodiment 1 emits ultraviolet light with a wavelength of 254nm.

[0042] In addition, the second filter component 30 can also serve as a backup for the first filter component 20. In practical applications, when the first filter component 20 reaches a certain usage period, the housing 10 of the air purification component 100 is disassembled, then the first filter component 20 disposed in the housing 10 is removed, and then the second filter component 30 is moved and installed at the position where the original first filter component 20 was located. Finally, the air purification component 100 is reassembled, thus realizing the recyclability of the air purification component 100. Among them, the usage period of the first filter component 20 is six months, that is, the first filter component 20 used in the air purification component 100 should be replaced every six months.

[0043] It can be understood that when the first filter component 20 reaches the usage period, the housing 10 of the air purification component 100 can also be disassembled, then the orientation of the fan 40 is changed, and finally the air purification component 100 is reassembled. During use, the original air inlet of the purification component 20 is used as the new air outlet and is installed and connected to the air conditioner 200, thus realizing the recyclability of the air purification component 100. That is, by changing the fan 40 and the orientation of the air purification component 100, the recyclability of the air purification component 100 is realized.

[0044] Among them, the first filter component 20 and the second filter component 30 can be made into two different forms, namely cylindrical and square plate forms, according to the body structure of the air purification component 100 and the air flow organization form, so as to improve the purification and filtration effect on the air flow and reduce the resistance suffered by the air flow when passing through the first filter component 20 and the second filter component 30.

[0045] As Figure 1 shown, the air purification component 100 is provided with a detachable structure, so that the air purification component 100 is detachably installed on the air inlet side of the air conditioner, and is convenient for movement and disassembly, as well as for recycling the filter component of the air purification component 100.

[0046] In the air inlet air purification component of the air conditioner in Embodiment 1, the air purification component 100 filters and purifies the air flow on the air inlet side of the air conditioner 200. After the air flow passes through the multiple filtration effects of the first primary filter screen 21, the first secondary filter screen 22, the first biological filter screen 23, and the first photocatalyst filter screen 25 in the air purification component 100, it not only realizes the function of filtering large particles such as hair and dust, but also can filter fine particles PM2.5, bacteria, formaldehyde and other pollutants, reduce the content of fungi such as Aspergillus flavus and viruses such as H1N1, thereby improving the indoor air quality; at the same time, after the air flow enters the air purification component 100, it completes the first filtration through the first filter component 20, and then the air flow is pressurized by the fan 40 and sent into the second filter component 30 to complete the second filtration. Thus, the air purification component 100 completes the comprehensive purification of the air flow after two filtrations.
