[0028] The bottom of the tank body 2 is provided with an air inlet 3. A lifting shaft 15 is provided within the air inlet 3, which can be raised and lowered. A one-way air check valve 12 and a limiting sleeve 16 are respectively sleeved on the upper and lower ends of the lifting shaft 15. A tension spring 13 is sleeved on the upper surface of the lifting shaft 15. The upper and lower ends of the tension spring 13 are respectively connected to the one-way air check valve 12 and the inner surface of the air inlet 3. A blocking platform 14 is provided above the air inlet 3. The blocking platform 14 and the one-way air check valve 12 are normally closed under the pull of the tension spring 13. By providing the one-way air check valve 12, lifting shaft 15, tension spring 13, limiting sleeve 16, and blocking platform 14, the air to be treated flows into the tank body through the air inlet under the combined action of the one-way air check valve 12, lifting shaft 15, tension spring 13, limiting sleeve 16, and blocking platform 14, and thus prevents the air from overflowing the tank body, thereby improving the efficiency of ozone generation.

[0029] In this embodiment, a motor 1 is installed at the top of the tank body 2, and a rotating shaft 9 is installed at the inner top of the tank body 2. After the power is turned on, the motor 1 will drive the rotating shaft 9 to rotate, thereby improving the efficiency of catalyzing air to produce ozone.

[0030] In this embodiment, a fixing frame 19 is provided at the inner bottom end of the tank body 2 , and the middle portion of the fixing frame 19 is interlaced with the bottom end of the rotating shaft 9 , so that the fixing frame 19 can fix the rotating shaft 9 .

[0031] In this embodiment, two ultraviolet lamps 10 are fixedly mounted on the surface of the rotating shaft 9. A filament 11 is provided inside each of the two ultraviolet lamps 10. When air flows into the tank, the ultraviolet rays emitted by the filament 11 radiate the air to produce ozone.

[0032] In this embodiment, the upper ends of the two ultraviolet lamp tubes 10 are each provided with a lamp tube positive electrode interface 18, and the lower ends of the two ultraviolet lamp tubes 10 are each provided with a lamp tube negative electrode interface 17. The inner top of the tank body 2 is provided with a positive electrode 7 and a negative electrode 8, and the top of the rotating shaft 9 is provided with a brush disk 20.

[0033] In this embodiment, three pairs of support blocks 31 are evenly distributed on the top of the exterior of the tank body 2. A rotating shaft 32 is inserted into the middle of each of the three support blocks 31. The middle end of the rotating shaft 32 is inserted into the top of a handle 33. The lock body 24 is axially connected to the handle 33 at a position slightly below the top. A retaining groove 27 is provided on either side of the lock body 24 at a position slightly above the middle end. A sliding block 28 is slidably connected to the interior of the two retaining grooves 27. The bottom end of the metal rod 26 is inserted into the middle of the sliding block 28. The outer side of the bottom end of the metal rod 26 is provided with a thread 29. A nut 30 is threadedly connected to the lower part of the bottom end of the metal rod 26. The spring 25 is inserted into the outer side of the middle end of the metal rod 26. The top end of the metal rod 26 is inserted into the top of the lock body 24. The top of the metal rod 26 is fixedly connected to the bottom of the lock ring 23. A sealing ring 34 is mounted on the inner bottom end of the lid 21, and a locking hook 22 is fixedly mounted on the outer bottom end of the lid 21. The middle portion of the locking ring 23 is connected to the locking hook 22. If the sealing of the lid 21 is not sufficient, the nut 30 on the metal rod 26 is tightened to adjust the tightness of the spring 25 to achieve the desired state.

[0034] The working principle of this device is: the tank body 2 is fixed in the working position by the bottom fixing ring 2, the power is turned on, and air flows into the tank body 2 through the air inlet 3. The motor 1 drives the rotating shaft 9 and the ultraviolet lamp tube 10 to rotate. After the positive electrode 7 and the negative electrode 8 are connected to the power supply, they form a slip ring power supply connection with the brush plate 20. The filament 11 emits ultraviolet rays, and the ultraviolet rays irradiate the air to catalyze and produce ozone.

[0035] The air that needs to be catalyzed enters from the air inlet, slightly lifting the one-way air check valve 12, and the ozone generated by the ultraviolet catalysis of the air will be discharged from the ozone outlet 6.

[0036] Open the ozone catalytic oxidation device, check and replace internal parts, and ensure the sealing of the device. When it is necessary to open the ozone catalytic oxidation device, rotate the handle 33 upwards, loosen the lock ring 23, remove the lock ring 23 from the lock hook 22, and then lift the cover 21 upwards, and the ozone catalytic oxidation device will be opened; when it is necessary to close the ozone catalytic oxidation device, close the cover 21, then put the lock ring 23 on the lock hook, and finally pull the handle 33 downwards, and the ozone catalytic oxidation device will be closed;

[0037] When the sealing performance of the cover is not sufficient, the tightness of the spring 25 can be adjusted by screwing the nut 30 on the metal rod 26 upwards, so as to adjust it to a suitable state.

[0038] Of course, the above description is not a limitation of the present invention, and the present invention is not limited to the above examples. Changes, modifications, additions or substitutions made by ordinary technicians in this technical field within the essential scope of the present invention also fall within the scope of protection of the present invention.
