[0028] As shown in FIGS. 1-2 and 4, an air purification lamp 1 provided by embodiments of the present application comprises: an air purification assembly 10 and an illumination assembly 20. The air purification assembly 10 and the illumination assembly 20 are both configured to be embedded within a bearing body. The air purification assembly 10 comprises: an air channel 11, a blower 12, and an HEPA filter 13. Two ends of the air channel 11 define therein an air inlet 111 and an air outlet 112, respectively. The blower 12 and the HEPA filter 13 are accommodated within the air channel 11. The HEPA filter 13 is coated with a sterilization coating 130 configured to kill coronaviruses. The illumination assembly 20 is arranged between the air inlet 111 and the air outlet 112. A light emitting surface of the illumination assembly 20 is configured to be exposed from a surface of the bearing body, and both the air inlet 111 and the air outlet 112 are arranged at a same plane.

[0029] Specifically, the bearing body refers to objects that can be installed with the air purification lamp 1, such as walls, suspended ceilings, cabinets, etc. For example, the suspended ceiling is generally installed at a ceiling of an office, a classroom, a restaurant, or other places to beautify the indoor environment. During the installation of the air purification lamp 1, the air purification assembly 10 and the illumination assembly 20 extend into a space between the suspended ceiling and the ceiling, and only an air inlet 111 of the air channel 11, an air outlet 112 of the air channel 11, and a light emitting surface of the illumination assembly 20 are exposed from the surface of the suspended ceiling, such that the main part of the air purification lamp 1 is hidden inside the suspended ceiling, and, the appearance is clean, tidy, beautiful, and novel. The air channel 11 is in a tubular part having an inner cavity. The air inlet 111 and the air outlet 112 are in communication with the inner cavity of the air channel 11. The air inlet 111 and the air outlet 112, as well as the light emitting surface of the illumination assembly 20 face a same side of the air channel 11. The blower 12 is accommodated inside the inner cavity of the air channel, thereby facilitating the indoor air to flow into the air channel 11 via the air inlet 111 and out of the air channel 11 via the air outlet 112. The HEPA filter 13 is disposed between the air inlet 111 and the air outlet 112, and configured to filter the air entering the inner cavity of the air channel 11. When passing through the HEPA filter 13, the air contacts with the sterilization coating 130 coated on the HEPA filter 13, such that the coronaviruses in the air are killed. The illumination assembly 20 is a conventional LED lamp, including LED

(light emitting diode) light groups, drivers, etc., and can be in fixed connection with the outer wall of the air channel.

[0030] The air purification lamp 1 provided by the present application adopts the air purification assembly 10 and the illumination assembly 20 which can be imbedded within the bearing body, and only the air inlet 111, the air outlet 112, and the light emitting surface of the illumination assembly 20 are exposed from the surface of the bearing body. In addition, the HEPA filter 13 is coated with a sterilization coating 130 configured to kill the coronaviruses, and the coronaviruses in the air passing through the HEPA filter 13 is killed by the sterilization coating 130. In this way, it is effectively solved the technical problem that the existing air purification lamp has poor concealment and is unable to kill the coronaviruses, the air purification 1 provided by the present application is beneficial to improving the appearance thereof and is conducive to the prevention and control of the new coronavirus epidemic.

[0031] Optionally, as shown in FIGS. 2-3, as a specific embodiment of the air purification lamp provided by the present application, the HEPA filter 13 covers the air outlet 112. Therefore, the air flowing out of the air outlet 112 inevitability passes through the HEPA filter 13, ensuring that the air entering the air channel 11 is completely filtered and sterilized before flowing into the external environment.

[0032] Optionally, as shown in FIG. 2 and FIG. 4, as a specific embodiment of the air purification lamp provided in the present application, the sterilization coating 130 is coated on a surface of the HEPA filter 13 away from the air channel 11. That is, the sterilization coating 130 is coated on the surface of the HEPA filter 13 away from the inner cavity of the air channel 11, which can effectively prevent the sterilization coating 130 from being covered by dust and affecting the contact area with the coronaviruses in the air, thus ensuring the effectiveness and the service life of the sterilization coating 130.

[0033] Optionally, as shown in FIG. 4, as a specific embodiment of the air purification lamp provided in the present application, the sterilization coating 130 is a GERMAGIC TMcoating. GERMAGIC TM isa sterilization technology owned by CHIAPHUA INDUSTRIES Co., Ltd., Hongkong, and has a strong oxidizing ability, which can oxidize and decompose the proteins of bacteria and viruses, and can effectively kill bacteria, new coronaviruses, and the like.

[0034] Optionally, as shown in FIG. 4, as a specific embodiment of the air purification lamp provided in the present application, the HEPA filter 13 is an H13 grade HEPA filter. The H13 grade HEPA filter is a filter having a filtration efficiency greater than 99.95% according to the EN1882-1 standard, and can filter most of the particulate pollutants in the air, such as: PM2.5, dust particles, dandruff, pollen, cigarette smoke, and all bacteria and microorganisms, etc. It can be understood that according to specific conditions and requirements, in other embodiments of the present application, the HEPA filter 13 may also be an HI1-level filter or an H12 level filter, in which, the filtration efficiency of the HI1-level filter is greater than %, and the filter efficiency of the H12-level filter is greater than 99.5%.

[0035] Optionally, as shown in FIG. 2, as a specific implementation of the air purification lamp provided by the present application, the air purification assembly 1 further includes a sterilization light 14, and the sterilization light 14 is arranged between the blower 12 and the high efficiency particulate air filter 13. In particular, the sterilization light 14 is a short-wave ultraviolet light having a wavelength in the range of between 200 and 275 nm (nanometers), which can photodegrade and denature bacterial proteins, thereby destroying and killing bacterial amino acids, nucleic acids, and enzymes. Since the blower12 is arranged at one end of the inner cavity of the air channel 11 approaching the air inlet 111 and is aligned with the air inlet 111, the air flowing in from the air inlet 111 of the air channel 11 will pass through the blower12 before being blown to the high efficiency particulate air filter 13, during which, the air will be exposed to the ultraviolet rays generated by the sterilization light 14, so that most of the bacteria and viruses in the air will be removed, and the air purification effect of the air purification lamp 1 will be further improved. According to specific conditions and requirements, the sterilization light 14 provided in some embodiments can be started synchronously with the blower 12 to kill bacteria and viruses in the air during the process of filtering the air, or can be started asynchronously with the blower12, and controlled alone by a controller, that is, the sterilization light 14 can be separately started when necessary.

[0036] Optionally, as shown in FIGS. 2-3 and 5, as a specific implementation of the air purification lamp provided by the present application, a sidewall of a central portion of the air channel 11 defines therein a through hole 113. The air purification assembly 10 further comprises a sterilization box 15. The sterilization box 15 is detachably connected with the sidewall of the central portion of the air channel and covers the through hole 113. The sterilization light 14 is accommodated within the sterilization box 15. In particular, the sterilization box 15 has an opening. When the sterilization box 15 is fixedly connected to the sidewall of the air channel 11, the opening of the sterilization box 15 in communication with the through hole 113, that is, the inner cavity of the sterilization box 15 is in communication with the inner cavity of the air channel 11. The sterilization light 14 is installed in the inner cavity of the sterilization box 15. The short-wave ultraviolet rays generated by the sterilization light 14 will be irradiated into the inner cavity of the air channel 11 via the through hole 113, thereby killing the bacteria and virus in the air within the inner cavity of the air channel 11. Because the sterilization light 14 is contained in the sterilization box , not only is the short-wave ultraviolet rays generated by the sterilization light 14 prevented from leaking into the indoor environment and from causing damage to the body of the indoor personnel, but also it is convenient for the installation of the sterilization light 14 at the air channel 11, thus ensuring the generated short-wave ultraviolet rays acting in the inner cavity of the air channel 11.

[0037] Optionally, as shown in FIG. 3, as a specific implementation of the air purification lamp provided by the present application, the air purification assembly 10 further comprises a primary efficiency particulate air filter 16, and the primary efficiency particulate air filter 16 covering the air inlet 11.

The high efficiency particulate air filter 13 is a plate structure and includes an outer frame and filter material. The outer frame can be a paper frame, aluminum frame, galvanized iron frame, etc. The filter material can be a non-woven fabric, nylon mesh, activated carbon, metal mesh, etc. The primary efficiency particulate air filter 16 covers the air inlet 111 of the air channel 11, and an air inlet of the blower 12 faces the primary efficiency particulate air filter 16. The air has to be firstly filtered by the primary efficiency particulate air filter 16 before passing through the blower 12, which effectively prevents large particulate pollutants from entering the blower 12 to damage to the blower 12, or from entering the inner cavity of the air channel 11 to block the air ventilation holes of the HEPA filter 13, and is therefore beneficial to extend the service life of the blower 12 and the HEPA filterl3.

[0038] Optionally, as shown in FIG. 1 and FIG. 3, as a specific implementation of the air purification lamp provided in this application, the air purification lamp 1 further comprises a frame 30 that surrounds the air inlet 111, the air outlet 112, and the illumination assembly 20, and the frame 30 is in fixed connection with the air channel 11 and the illumination assembly 20, respectively. Specifically, the frame 30 is arranged around edges of the plane where the air inlet 111 of the air channel 11, the air outlet 112 of the air channel 11, and the light emitting surface of the illumination assembly 20 are located. Edges of two long sides of the illumination assembly 20 are respectively fastened to center portions of two long sides of the frame 30. The two short sides of the frame 30, end parts of the two long sides of the frame 30, and edges of the two short sides of the illumination assembly 30 are enclosed to form two escape openings 300, respectively. The two escape openings 30 respectively correspond with the air inlet 111 of the air channel 11 and the air outlet 112 of the air channel 11. Two ends of the air channel 11 are in fixed connection with two ends of the frame 30, respectively, thereby forming a complete air purification lamp 1. When the air purification lamp 1 is installed at the bearing body, the frame 30 can be embedded in the surface of the bearing body, so that the air purification lamp 1 has better appearance and concealment.
