The meaning of "a plurality of' or "multiple" is two or more unless otherwise specifically defined.

[0027] As shown in FIGS. 1-3, an air purification illuminator 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 is accommodated within one end of the air channel 11 approaching the air inlet 111 of the air channel 11. The HEPA filter 13 is accommodated within one end of the air channel 11 approaching the air outlet 112 of the air channel 11 and covers the air outlet 112 of the air channel 11. The illumination assembly 20 is arranged between the air inlet 111 of the air channel 11 and the air outlet 112 of the air channel 11. A light emitting surface of the illumination assembly is configured to be exposed from a surface of the bearing body, and both the air inlet 111 of the air channel 11 and the air outlet 112 of the air channel 11 are arranged at a same plane.

[0028] In some embodiments, the bearing body refers to objects that can be installed with the air purification illuminator 1, such as walls, suspended ceilings, cabinets, etc. For example, the suspended ceiling is generally installed on a ceiling of an office, a classroom, a restaurant, or other places to beautify the indoor environment. During the installation of the air purification illuminator 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 illuminator 1 is hidden inside the suspended ceiling, 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 at one end approaching the air inlet 111, 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 can adopt an H11, H12, or H13 filter, which can filter out more than % of particulate pollutants, such as, PM2.5, dust particles, dandruff, pollen, cigarette smoke, and all bacteria and microorganisms, etc. The illumination assembly is a conventional light emitting diode (LED) lamp, including LED light groups, drivers, etc., which can be in fixed connection with an outer wall of the air channel 11.

[0029] The air purification illuminator 1 provided by the present application adopts a combination of the illumination assembly 20 and the air purification assembly 10 to achieve both the functions of air purification and illumination. By mounting the blower 12 at the air inlet 111 of the air channel and mounting the HEPA filter 13 at the air outlet 112 of the air channel, the wind resistance at the front end of the air channel 11 is small, the wind speed in the air channel 11 gradually decreases from the front end to the rear end, so that the air outlet 112 of the air channel 11 has soft and uniform wind speed and low noises, which effectively solves the technical problem that the existing air purifier has loud noises at the air outlet and single function. The air purification illuminator 1 is capable of satisfying multiple use needs of the user, as well as avoiding the generation of loud noises, which is conducive to improvement of the user's use experience.

[0030] Optionally, as shown in FIG. 1 and FIG. 2, as a specific implementation of the air purification illuminator provided in this application, the air purification illuminator 1 further comprises a frame 30 that surrounds the air inlet 111 of the air channel 11, the air outlet 112 of the air channel 11, and the illumination assembly 20, and the frame 30 is fastened to 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 and the air outlet 112. The two ends of the air channel 11 are infixed connection with two ends of the frame 30, thereby forming a complete air purification illuminator 1. When the air purification illuminator 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 illuminator 1 has better appearance and concealment.

[0031] Optionally, as shown in FIG. 3, as a specific implementation of the air purification illuminator provided in this application, the air purification assembly 10 further comprises a primary efficiency particulate air filter 14. The primary efficiency particulate air filter 14 covers the air inlet 111 of the air channel 11. The primary efficiency particulate air filter 14 is mainly used to filter dust and particles above 5

m (micrometers), and adopts a plate structure including an outer frame and a filter material. The outer frame can be a paper frame, an aluminum frame, a galvanized iron frame, etc. The filter material can be a non-woven fabric, a nylon mesh, an activated carbon, a metal mesh, etc. The primary efficiency particulate air filter 14 covers the air inlet 111 of the air channel 11, and the air inlet of the blower 12 faces the primary efficiency particulate air filter 14. The air has to be firstly filtered by the primary efficiency particulate air filter 14 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 vents of the HEPA filter 13, and is therefore beneficial to extending the service life of the blower 12 and the HEPA filter 13.

[0032] Optionally, as shown in FIGS. 3-5, as a specific implementation of the air purification illuminator provided in this application, the blower 12 comprises: a motor 121 and a wind wheel 122. The wind wheel 122 is sheathed outside a driving shaft 1211 of the motor 121. The air purification assembly 10 further comprises a blower bracket 15. The blower bracket 15 is in fixed connection with the air inlet 111 of the air channel 11. The motor 121 is in fixed connection with a surface of the blower bracket 15 facing the air channel 11. Particularly, the blower bracket 15 is in fixed connection with a sidewall of the air channel 11 and covers the air inlet 111 of the air channel 11. The motor 121 is in fixed connection with a surface of the blower bracket facing the inner cavity of the air channel 11. The wind wheel 122 is accommodated at an end of the inner cavity of the air channel 11 approaching the air inlet 111 of the air channel 11 and in fixed connection with the driving shaft 1211 of the motor 121. An air outlet direction of the wind wheel 122 is perpendicular to an axial direction of the driving shaft. Because an inner contour at the end of the inner cavity of the air channel 11 in the proximity of the air inlet 111 of the air channel 11 adopts a shape of an Arabic numeral 6, that is, an opening area at the air inlet 111 of the air channel 11 is larger, and an opening area at a position connected to a middle of the air channel 11 is smaller, the indoor air having entered the inner cavity via the air inlet 111 of the air channel 11 is allowed to flow to the air outlet 112 of the air channel 11 at a relatively high flow velocity and volume, the indoor air is enabled to quickly pass through the HEPA filter 12, and the purification speed of the indoor air is improved.

[0033] Optionally, as shown in FIG. 4, as a specific implementation of the air purification illuminator provided in this application, the blower 12 further comprises a motor bracket 123. The motor bracket 123 is infixed connection with the motor 121. The motor 121 is infixed connection with the blower bracket 15 via the motor bracket 123. In particular, the motor 121 further comprises a motor casing 1212. The driving shaft 1211 passes through the motor casing 1212 and protrudes out of the motor casing 1212. The motor bracket 123 comprises: a bracket body 1231, at least two support portions 1232, and at least two buffer washers 1233. The bracket body 1231 defines therein an escape hole 12311 configured for escaping the driving shaft 1211 of the motor 121, and a plurality of mounting holes 12312 configured for allowing the screws to pass through. The escape hole 12311 is arranged at a central portion of the bracket body 1231, and the plurality of mounting holes 12312 surround the escape hole 12311 and are spaced apart from each other. When the motor bracket 123 is to be mounted at the motor 121, the motor bracket 12 is firstly sleeved on the motor casing 1212 by escaping the driving shaft 1211 via the escape hole 12311, a plurality of screws are inserted into the mounting holes 12312 and screwed into the motor casing 1212, such that the motor bracket 123 is infixed connection with the motor casing 1212, and a plane where the motor bracket 123 is located is perpendicular to an axis of the driving shaft 1211. At least two support portions 1232 are integrally formed with the bracket body 1231 and extend outwards from an edge of the bracket body 1231 along a parallel plane. That is, the respective support portions 1232 extend outwards from the edge of the bracket body 1231 in a direction in parallel to a plane where the bracket body 1231 is located. The at least two support portions 1232 are spaced apart from each other along a circumferential direction, that is, the at least two support portions 1232 surrounds the bracket body 1231 and are spaced apart from each other. The buffer washers 1233 are arranged at the support portions 1232 in a manner of one-to-one correspondence, that is, each buffer washer 1233 is arranged at each support portion 1232. The support portions 1232 are in fixed connection with the blower bracket 15 via the buffer washers 1233. In this way, it is avoided the rigid connection between the motor bracket 123 and the blower bracket 15, and it is also avoided that the vibration generated by the motor 121 is transmitted to the air channel 11 via the motor bracket 123 and the blower bracket 15, thereby effectively reducing the noises caused by the vibration of the motor 121. In addition, due to the connection between the motor bracket 123 and the motor 121, the motor bracket 123 has strong versatility, motors of different specifications and models can be installed at the blower bracket 15, which is beneficial to reducing the difficulty and cost for the design and purchase of the motor.

[0034] Optionally, as shown in FIG. 4, as a specific implementation of the air purification illuminator provided in this application, each of the support portions 1232 defines therein a bayonet 12320 at an end thereof away from the bracket body 1231. A sidewall of each of the buffer washers 1233 defines therein a mounting groove 12330. Each of the buffer washers 1233 is accommodated within the bayonet 12320, an edge of the bayonet 12320 extends into the mounting groove 12330 to form a bayonet coupling with each of the buffer washers 1233. Specifically, the bayonet 12320 has a large opening and small body, an inner diameter of the bayonet 12320 is greater than an inner diameter of the buffer washer 1233 and smaller than an outer diameter of the buffer washer 1233. The mounting groove 12330 is an annular groove and extends along an axis of the buffer washer 1233. A longitudinal section of the mounting groove 12330 is perpendicular to an axis of the buffer washer 1233. When assembling the buffer washer 1233 and the support portion 1232, the mounting groove 12330 is aligned with the edge of the bayonet 12320, and the buffer washer 1233 is pushed into bayonet 12320, such that an edge of the bayonet 12320 is gradually extended into the mounting groove 12330 until the buffer washer 1233 is completely accommodated within the bayonet 12320. In this way, the buffer washer 1233 is in fixed connection with the support portion 1232.

[0035] Optionally, as shown in FIGS. 4-6, as a specific implementation of the air purification illuminator provided in this application, a surface of the blower bracket facing the air channel 11 is provided with at least two bosses 152. Installation columns 1520 are arranged at middle portions of the at least two bosses 152, respectively. The installation columns 1520 extend into inner holes of the buffer washers 1233, respectively. The buffer washers 1233 are in fixed connection with the bosses 152 by screwing screws into the installation columns 1520. In particular, a grid 151 is arranged at the blower bracket 15, the grid 151 is aligned with the air inlet 111 of the air channel 11, a coverage area of the grid 151 is smaller or equal to a coverage area of the air inlet 111 of the air channel 11, and the indoor air is able to passes through the blower bracket 15 via the grid 151 to enter the inner cavity of the air channel 11. The bosses 152 and the support portions 1232 of the blower bracket 15 are arranged in a manner of one-to-one correspondence. At least two bosses 152 extend from a surface of the grid 151 facing the inner cavity of the air channel 11 towards the inner cavity of the air channel 11 with a certain height, and spaced apart from each other and surround the central axis of the grid 151. The installation columns 1520 extend from end surfaces of the bosses 152 to a certain height along a central axis of the bosses 152. An area of the cross section of each installation column

1520 is smaller than an area of the cross section of each boss 152. A convex height of each installation column 1520 is smaller than an axial thickness of the buffer washer 1233, and a coverage area of an inner hole of the buffer washer 1233 is smaller than an area of the end surface of the boss 152 away from the grid 151. During assemblage of the motor bracket 123 and the blower bracket 15, at least two buffer washers 1233 are sleeved outside the at least two installation columns 1520, respectively, screws are extended into the inner holes of the buffer washers 1233 and screwed into the threaded holes of the installation columns 1520, thus the buffer washers 1233 are fastened to the bosses 152, and the motor bracket 123 is infixed connection with the blower bracket 15.

[0036] Optionally, as shown in FIG. 4, as a specific implementation of the air purification illuminator provided in this application, the motor bracket 123 further comprises a stiffener 1234. The stiffener 1234 extends along an edge of the bracket body 1231 and an edge of the support portion 1232. In particular, the stiffener 1234 is a flange, and is formed by flanging an edge of the bracket body 1231 in proximity of the support portion 1232 and an edge of the support portion 1232 in proximity of the bracket body 1231 to 90 degrees, thus, the intensity of the integral structure of the motor bracket 123 is improved.

[0037] Optionally, as shown in FIGS. 4-5, as a specific implementation of the air purification illuminator provided in this application, a central portion of a bottom wall of the wind wheel 122 defines therein a first limiting hole 1222 in fitness with the driving shaft 1211 of the motor 121, and a cross section of the first limiting hole 1222 is in a shape of a segmental circle. In particular, the driving shaft 1211 of the motor 121 is provided with a segmental cylinder portion, with a cross section thereof in a shape of a segmental circle. The contour of the cross section of thefirst limiting hole 1222 is fitted to the contour of the cross section of the driving shaft 1211. The wind wheel 122 is inversely arranged at the motor 121. By fitting the first limiting hole 1222 with the segmental cylinder portion of the driving shaft 1211 of the motor 121, the motor 121 is able to drive the wind wheel 122 to rotate.

[0038] Optionally, as shown in FIGS. 4-5, as a specific implementation of the air purification illuminator provided in this application, the central portion of the bottom wall of the wind wheel 122 further defines therein at least two locking grooves 1223, and the at least two locking grooves 1223 are spacedly arranged around the first limiting hole 1222. The blower 12 further includes a reinforcement piece 124. The reinforcement piece 124 includes a reinforcement body 1241 and at least two locking pins 1242. A central portion of the reinforcement body 1241 defines therein a second limiting hole 12410 having a shape matching with a shape of the first limiting hole 1222. The at least two locking pins 1242 extend outwards from an edge of the reinforcement body 1241 along a vertical direction and are inserted into the at least two locking grooves 1223, respectively. In particular, the locking groove 1223 is defined in the central portion of the surface of the wind wheel 122 far away from the air inlet 1221 of the wind wheel 122, the positions of the at least two locking grooves 1223 correspond to the positions of the at least two locking pins 1242 of the reinforcement piece 124. When the locking pins 1242 are inserted into the locking grooves 1223 in a manner of one-to-one correspondence, the projections of the second limiting hole 12410 and the first limiting hole 1222 on the reinforcement body 1241 coincide. When the wind wheel 122 is installed at the motor 121, the segmental cylinder portion of the driving shaft 1211 of the motor 121 is inserted into the first limiting hole 1222 and the second limiting hole 12410 in sequence. In this way, a circumferential force generated during the rotation of the driving shaft 1211 of the motor 121 not only acts on the first limiting hole 1222, but also is transmitted to the reinforcement piece 124 via the second limiting hole 12410, therefore, the reinforcement piece 124 bears a part of the circumferential force, thereby avoiding the wind wheel 122 made of plastic materials from being damaged and effectively prolongs the service life of the wind wheel 122.
