DETAILED DESCRIPTION

[0019] The utility model is further described below in conjunction with the accompanying drawings.

[0020] Reference Figure 1-4As shown, the air sterilizing and disinfecting machine comprises a cabinet 1, an air inlet 101 is provided on the outer peripheral wall below the cabinet 1, and an air outlet 102 is provided on the outer peripheral wall above the cabinet 1. The cabinet 1 is a rectangular structure, and the air inlet 101 and the air outlet 102 are provided on the outer walls around the cabinet 1. External air enters the interior from the air inlet 101 and is discharged from the air outlet 102 after being filtered and purified. A filter screen 2 is provided above the air inlet 101 to filter the hair in the external air. Hair, dust, debris, etc., the filter screen plate is composed of a mesh surface and a edging arranged on the periphery of the mesh surface. Inside the cabinet 1, a mounting frame 3 with a rectangular structure is arranged above the air inlet 101. The outer peripheral wall of the mounting frame 3 is fixedly connected to the inner peripheral wall of the cabinet 1. The four corners of the inner wall of the mounting frame 3 are all provided with right-angle limiters 4, and the right-angle limiters 4 are provided with right-angle placement grooves 401. The four corners of the filter screen plate 2 are located inside the right-angle placement grooves 401. The top cover 7 is provided on one side of the right-angle placement groove 401, and the top cover 7 is closed on the top of the right-angle placement groove 401. The filter screen plate 2 is placed from the top of the mounting frame 3, and the four corners of the filter screen plate 2 are placed into the right-angle placement groove 401 of the right-angle limiter 4. The top cover 7 is driven to rotate to the top of the filter screen plate 2 through the rotating block 6 on the connecting shaft 5 to close the right-angle placement groove 401. Since the rotating block 6 can only rotate horizontally on the connecting shaft 5, the top cover 7 is limited in the axial direction, so that the filter screen plate 2 will not be separated from the right-angle placement groove 401. When disassembling, it is only necessary to rotate the rotating block 6 to rotate the top cover 7 to the side away from the right-angle placement groove 401, so as to remove the filter screen plate 2. The filter screen plate 2 can be installed in the cabinet 1 and disassembled from the cabinet 1 without special tools, which is convenient for later maintenance and cleaning of the filter screen plate, and more convenient to use.

[0021] Preferably, a gripping portion 8 is provided on a side of the rotating block 6 away from the top cover 7 , and the gripping portion 8 facilitates the operation of rotating the rotating block 6 .

[0022] Preferably, a connecting plate 9 is provided between adjacent right-angle limit members 4, and the inner wall of the connecting plate 9 is in conflict with the edge of the filter mesh plate 2. The connecting plate 9 improves the integrity between the right-angle limit members 4 and cooperates with the filter mesh plate 2 to prevent external air from passing through the mounting frame 3 without being filtered by the filter mesh plate 2, thereby improving the filtering effect on hair, dust and debris.

[0023] Preferably, a first mounting plate 10 is arranged above the filter screen plate 2, through holes are evenly opened on the first mounting plate 110, at least one exhaust fan 11 is arranged at the bottom of the first mounting plate 10, and two exhaust fans 11 can be provided. The exhaust fan 11 guides external air into the cabinet 1 from the air inlet 101, and is filtered by the filter screen plate 2 before being sent to the rear side.

[0024] Preferably, a multi-layer ion tube assembly 12 is arranged above the first mounting plate 10. The ion tube assembly 12 generates plasma for sterilization. It is a prior art and will not be described in detail here. The ion generating elements of each group of ion tube assemblies 12 are arranged from front to back. The setting of the multi-layer ion tube assembly 12 makes the air disinfection effect better.

[0025] Preferably, a second mounting plate 13 is provided above the topmost ion tube assembly, and through holes are evenly opened on the second mounting plate 13. An activated carbon block 14 is placed on the top of the second mounting plate, and the activated carbon block 14 is used to purify the air, absorb odors, etc.

[0026] Preferably, a switch door 15 is hinged on the front end surface of the cabinet 1, and the switch door 15 is used to open or close the cabinet 1, so that the filter plate 2 and the activated carbon block 14 can be easily replaced.

[0027] The above description is only a preferred embodiment of the present invention and does not limit the present invention in any form. Any simple modification or equivalent changes made to the above embodiments based on the technical essence of the present invention shall fall within the protection scope of the present invention.
