DETAILED DESCRIPTION OF THE EMBODIMENTS

[0030] In order to make the object, technical solutions, and advantages of the present invention more clear, the present invention is further described in detail below with reference to the drawings and examples. It should be understood that the specific examples described herein are merely intended to explain the present invention, rather than to limit the present invention.

[0031] As shown in FIG. 1, the plasma air sterilizer implemented by the present invention at least includes a fan assembly 2, a plasma generator 3, a plasma generator channel 4, and a grounded metal isolation mesh 1.

[0032] The fan assembly 2 is a drum-type fan with side air intake, which generates uniform air stream to a flat channel and outputs the uniform air stream to the plasma generator channel 4; the plasma generator channel 4 has a flat structure and is connected to the plasma generator 3; and the plasma generator 3 generates plasma to sterilize air.

[0033] As shown in FIG. 2, three division boards 41 may be arranged inside the plasma generator channel 4, and a spacer 42 may be arranged on an inner wall of the plasma generator channel 4 to support the three division boards 41. The three division boards 41 may divide an air flow to produce a laminar flow effect, which is convenient for plasma sterilization.

[0034] A grounded metal isolation mesh 1 may be arranged at an outlet of the plasma generator channel 4, which plays an isolation role for safety protection and prevents a destroyer from being inserted into a high-voltage area; and the grounded metal isolation mesh 1 also can shield and filter possible positive and negative ions generated by the plasma generator channel 4. Thus, an air inlet of the plasma generator channel 4 may be also provided with a grounded metal isolation mesh 1.

[0035] An edge of the grounded metal isolation mesh 1 may be provided with a snap 11; correspondingly, a frame of the plasma generator channel 4 may be provided with a snap hole 43; and the arrangement and fixation of the grounded metal isolation mesh 1 may be realized by inserting the snap 11 into the snap hole 43.

The plasma generator 3 is an existing device capable of generating plasma and the fan assembly 2 is an existing drum-type fan, which can be realized by the existing technologies and thus will not be repeated here.

[0037] In order to match the flat structure of the plasma generator channel 4, the plasma generator 3 can also be designed into a flat shape.

[0038] In the sealed whole formed by a plasma high-voltage generation circuit 3 operating under a 24 V power supply and the plasma generator channel 4, a drum-type fan composed of a motor operating under a 24 V power supply generates an air flow, and the fan assembly 2 generates a strip-like air source; the air passes through the plasma generator channel 4 to play the role of air circulation sterilization; and the grounded metal isolation mesh 1 can not only prevent a destroyer from being inserted into a high-voltage area, but also shield and filter positive and negative ions generated by the plasma generator channel 4.

Moreover, a circulating plasma sterilization mode enables the continuous sterilization of indoor air, is not limited to local sterilization, and shows a prominent sterilization effect.

[0043] Moreover, the present invention adopts a plane to form a long channel that enables small air resistance and easy sealing and also adopts a grounded metal isolation mesh to prevent destructive electric shock caused by the insertion of a metal bar, making the sterilizer safe and reliable.

[0044] The above-mentioned structural mode of the present invention can adopt an overall sealing and water-proof design to make the entire sterilizer water-proof, a power supply mode of 24 V safe voltage to avoid hidden safety hazards of electric shock, and a metal mesh to further shield positive and negative ions generated by the plasma assembly.

[0045] The basic structure of the present invention is described above. In practical applications, the components of the present invention can be assembled into various products with different air flow rates according to actual needs and can also be assembled into a ceiling air duct-type sterilizer, where one component is adopted as a unit, and 1 to N units form a product series with different air volumes.
