[0035] The present utility model will be further described in combination with the following embodiments.

[0036] Embodiment 1.

[0037] As Figures 1-3 shown, a clean room air purification and disinfection device includes a positioning top plate 1. An air inlet pipe 2 is fixedly installed at the top of the positioning top plate 1. An equipment housing 3 is fixedly installed at the bottom of the positioning top plate 1. A filter pipe 4 is fixedly installed inside the equipment housing 3 at the bottom of the positioning top plate 1. The filter pipe 4 is communicated with the air inlet pipe 2. The output end of the filter pipe 4 is connected with an air outlet pipe 5. A positioning sleeve 6 is fixedly installed below the positioning top plate 1 outside the filter pipe 4. An air outlet fan 7 is fixedly installed inside the positioning sleeve 6. The air outlet pipe 5 is cooperatively connected with the air inlet of the air outlet fan 7.

[0038] This application is used for air purification and disinfection of a clean room. First, the positioning top plate 1 is fixedly installed on the ceiling of the clean room by bolts, and then it is connected to an external circulating air intake device through the air intake pipe 2 to introduce fresh air from the outside into the air intake pipe 2. The fresh air passes through the filter layer inside the filter pipe 4 for filtration, and then the fresh air is sent into the air inlet of the air outlet fan 7 through the air outlet pipe 5, so that the clean fresh air can be sent into the clean room.

[0039] An angle-adjustable air duct assembly 8 is rotatably sleeved outside the positioning sleeve 6. The bottom of the angle-adjustable air duct assembly 8 extends outside the equipment housing 3 and is rotatably installed with the equipment housing 3. A driving mechanism is fixedly installed inside the equipment housing 3 below the positioning top plate 1. The driving mechanism is in transmission cooperation with the angle-adjustable air duct assembly 8. A spraying mechanism is also installed inside the equipment housing 3, and the spraying mechanism is in movable cooperation with the angle-adjustable air duct assembly 8.

[0040] The fresh air sent into the clean room can change the blowing angle through the angle-adjustable air duct assembly 8, increasing the blowing range of the clean fresh air. The angle-adjustable air duct assembly 8 is driven to rotate by the driving mechanism. At the same time, the spraying mechanism installed inside the equipment housing 3 atomizes and sprays the disinfectant. By using the continuously rotating angle-adjustable air duct assembly 8, the fresh air can be combined with the spraying mechanism, making the atomization spraying range of the disinfectant wider, improving the disinfection spraying range, and improving the air purification and disinfection efficiency of the clean room.

[0041] The angle-adjustable air duct assembly 8 includes an outer rotating sleeve 81. The outer rotating sleeve 81 is rotatably sleeved outside the positioning sleeve 6. A gear ring A 82 is fixedly installed outside the outer rotating sleeve 81. The driving mechanism includes a driving motor 9 fixed below the positioning top plate 1. The output end of the driving motor 9 is fixedly installed with a rotating shaft 10. A gear ring B 11 is fixedly installed outside the rotating shaft 10. The gear ring A 82 and the gear ring B 11 are meshed with each other. The outside of the outer rotating sleeve 81 is rotatably and limitedly installed on the bottom wall of the equipment housing 3 through two limiting blocks 83. An inclined air blowing pipe 84 is spirally installed inside the outer rotating sleeve 81.

[0042] The angle-adjustable air duct assembly 8 drives the rotating shaft 10 to rotate through the output of the driving motor 9, and then drives the gear ring B 11 to rotate through the rotating shaft 10. The gear ring B 11 drives the gear ring A 82 meshed with it to rotate. The gear ring A 82 drives the outer rotating sleeve 81 to rotate. The outer rotating sleeve 81 rotates outside the positioning sleeve 6 and drives the inclined air blowing pipe 84 to rotate at an inclined angle, blowing fresh air into the clean room obliquely and realizing rotation, increasing the blowing range of the fresh air.

[0043] The spraying mechanism includes a water tank 12 fixedly installed below the positioning top plate 1. A main water pipe 13 and a water pump 14 are fixedly installed below the water tank 12. At least two branch water pipes 15 are connected to the bottom of the main water pipe 13. One end of the branch water pipe 15 away from the main water pipe 13 extends to the outside of the equipment housing 3 and is installed with an atomizing nozzle 16.

[0044] The spraying mechanism pumps the disinfectant liquid inside the water tank 12 into the inside of a number of branch water pipes 15 through the water pump 14, and then sprays it out from the atomizing nozzles 16. A control valve is installed on each branch water pipe 15.

[0045] The atomizing nozzles 16 are distributed in a circumferential array with the rotation axis 10 of the outer rotating sleeve 81 as the axis.

[0046] The atomizing nozzles 16 are distributed around the outer rotating sleeve 81. When the inclined air blowing pipe 84 rotates, it can further blow obliquely the disinfectant liquid sprayed out from the surrounding atomizing nozzles 16, increasing the spraying range of the disinfectant liquid and improving the air purification and disinfection spraying efficiency of the clean room.

[0047] The utility model drives the angle-adjusting air pipe assembly 8 to rotate through the driving mechanism, blows the external clean air into the inside of the clean room at an inclined angle, and realizes the rotating blowing, so that the blowing range of the fresh air in the clean room is wider, and it cooperates with the surrounding atomizing nozzles 16, and can also make the spraying range of the disinfection atomizing liquid wider during disinfection, improving the air purification and disinfection efficiency of the clean room.

[0048] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the utility model rather than to limit the protection scope of the utility model. Although the utility model has been described in detail with reference to the preferred embodiments, those of ordinary skill in the art should understand that the technical solutions of the utility model can be modified or equivalently replaced without departing from the essence and scope of the technical solutions of the utility model.
