[0026] The present invention will be further described below in conjunction with the accompanying drawings.

[0027] Example

[0028] refer to Figures 1 to 12 A multi-stage purification ceiling-mounted air purification device includes an outer shell 9, one end of the outer shell 9 has an air outlet fence 91, and the other end has an air inlet fence 92.

[0029] A multi-dimensional disinfection module is provided in the outer shell 9, and the multi-dimensional disinfection module includes a grating module 1 and a light source module 2. The grating module 1 is a block structure and has a plurality of horizontally arranged air guide channels 11. The inner wall of the air guide channel 11 is coated with a photocatalyst coating. The two ends of the air guide channel 11 extend to the two end surfaces of the grating module 1 respectively. The top two ends and the bottom two ends of the grating module 1 respectively have a plurality of vertically arranged light-transmitting holes 12, and each air guide channel 11 is connected to at least one corresponding light-transmitting hole 12.

[0030] The air guide channel 11 of this embodiment can adopt the following shapes: Fig.10 The linear channel, such as Fig.11 The obliquely arranged oblique channel can also be formed by Fig.12The difference between the V-shaped channel structure with a curved middle portion and the structure is that the surface area of ​​the side wall of the air guiding channel 11 is increased by extending the length of the air guiding channel 11, thereby increasing the active area of ​​the photocatalyst coating and improving the purification efficiency.

[0031] The grating module 1 of this embodiment is further described below using the air guide channel 11 with a V-shaped channel structure.

[0032] The light source modules 2 include two, which are respectively located at the top and bottom of the grating module 1, and each light source module 2 has a plurality of catalytic light sources 21, which are arranged in two rows and correspond one to one with the light-transmitting holes 12. The light source module 2 used in this embodiment is an LED light board, and the catalytic light source 21 is an LED lamp bead.

[0033] In the above structure, the inner wall of the grating module 1 and the air guide channel 11 has a photocatalyst coating, and the light source module 2 provides a catalytic light source 21 for the photocatalyst coating. Each air guide channel 11 is connected to at least one light-transmitting hole 12, and the catalytic light source 21 is arranged one-to-one with the light-transmitting hole 12, so that each LED lamp bead of the LED light board is irradiated into the air guide channel 11, and the irradiation is close, which has the characteristics of high irradiation intensity and high efficiency, and effectively solves the technical problem of blind spots in the air guide channel 11, and the grating module 1 with a photocatalyst coating kills and decomposes the odor of the passing airflow.

[0034] Further, in this embodiment, if Figure 5 and Figure 6 As shown, the air guide channel 11 is evenly arranged in two layers, upper and lower. The light-transmitting holes 12 at both ends of the top of the grating module 1 are just so that the top of the upper air guide channel 11 corresponds to the two sides of the transverse cavity 14 and are respectively provided with light-transmitting holes 12. The light-transmitting holes 12 at both ends of the bottom of the grating module 1 are just so that the bottom of the lower air guide channel 11 corresponds to the two sides of the transverse cavity 14 and are respectively provided with light-transmitting holes 12. In the above structure, the air guide channel 11 arranged in two layers, upper and lower, also serves the purpose of increasing the effective area of ​​the photocatalyst coating, and the light-transmitting holes 12 respectively arranged on both sides of the transverse cavity 14 of the air guide channel 11, in conjunction with the two light source modules 2 arranged upper and lower, effectively improve the illumination intensity and uniformity of the catalytic light source 21 to the air guide channel 11.

[0035] Further, if Figure 2 As shown, a photocatalyst filter 4 is further provided between the grating module 1 and the air inlet fence 92 in the outer shell 9. In the above structure, when the airflow passes through the photocatalyst filter 4, in addition to filtering dust, the photocatalyst on the filter 4 can also use the catalytic light source 21 of the multi-dimensional disinfection module to perform preliminary disinfection on the airflow, and at the same time, it can also prevent the filter 4 from becoming moldy and producing odor after long-term dust accumulation.

[0036] Further, if Figure 4 As shown, an air purification module 5 is also provided between the grating module 1 and the air outlet fence 91 in the outer shell 9. The air purification module 5 described in this embodiment specifically adopts an air ionization device. In the above structure, after the airflow passes through the first-level disinfection of the photocatalyst filter 4, it enters the air guide channel 11 of the multi-dimensional disinfection module, and the "photocatalyst" + "UVC" of the multi-dimensional disinfection module performs a second-level disinfection with double disinfection effects. The airflow that has passed the first and second-level disinfection then flows through the air purification module 5, and the ion sheet of the air purification module 5 ionizes the air to produce positive and negative ions to achieve third-level disinfection. Finally, the airflow that has passed the first, second, and third-level disinfection is sent to the environment, which can effectively reduce the number of microorganisms and odors in the air, and achieve excellent and efficient air purification function.

[0037] Further, if Figure 3 and Figure 4 As shown, a plurality of fans 6 are provided between the grating module 1 and the air purification module 5 in the outer shell 9, and the fans 6 can force air from the air inlet fence 92 to the air outlet fence 91. In the above structure, under the forced air supply of the fans 6, the air in the outer shell 9 is sent to the environment from the air inlet fence 9 → the photocatalyst filter 4 → the grating module 1 of the multi-dimensional disinfection module → the air purification module 5 → the air outlet fence 91.

[0038] Further, in this embodiment, if Figures 7 to 9 As shown, the side wall of the air guide channel 11 has a plurality of convex portions 13. In the above structure, the convex portions 13 increase the surface area of ​​the side wall of the air guide channel 11, thereby increasing the active area of ​​the photocatalyst coating and improving the purification efficiency.

[0039] Further, in this embodiment, if Figure 7 As shown, the convex part 13 is a strip-shaped structure arranged along the length direction of the air guide channel 11, and its cross section is sawtooth-shaped. In the above structure, the strip-shaped convex part 13 has the characteristics of easy manufacture and simple structure on the basis of increasing the active area of ​​the photocatalyst coating.

[0040] Further, in this embodiment, if Figures 5 to 9 As shown, the middle part of the grating module 1 has a transverse cavity 14 that crosses the air guide channel 11, and the two ends of the transverse cavity 14 extend to the two sides of the grating module 1 respectively. Two UVC lamp boards 3 are respectively arranged on both sides of the grating module 1 to block the two ends of the transverse cavity 14, and the UVC lamp beads 31 of the UVC lamp board 3 face the transverse cavity 14. In the above structure, by providing UVC light into the transverse cavity 14, the airflow entering the air guide channel 11 is sterilized by the UVC light when passing through the transverse cavity 14, thereby realizing the dual sterilization effect of "photocatalyst" + "UVC", and achieving the technical effect of three-dimensional sterilization.

[0041] When the multi-stage purification ceiling-mounted air purification device of the present embodiment is in operation, the built-in fan 6 draws air from the environment into the outer shell 9 of the present embodiment, and after the first-level disinfection by the photocatalyst filter 4, it enters the air guide channel 11 of the multi-element three-dimensional disinfection module, and the "photocatalyst" + "UVC" of the multi-element three-dimensional disinfection module performs a second-level disinfection with dual disinfection effects. The airflow that has undergone the first and second-level disinfection flows through the air purification module 5 again, and the ion sheet of the air purification module 5 ionizes the air to produce positive and negative ions to achieve three-level disinfection. The air that has undergone multi-stage disinfection by different factors in the above three stages returns to the environment, realizing multi-stage air disinfection of the ambient air. At the same time, the air that has undergone multi-stage air disinfection is mixed with the ambient air, and then circulated back to the device under the forced air supply of the built-in fan 6, and is repeatedly subjected to multi-stage air disinfection and purification by the device. The airflow circulates back and forth in this way, effectively reducing the number of microorganisms and odor molecules in the air, and realizing excellent and efficient air purification function.
