[0024] The tip of the discharge alloy needle 1 discharges, forming a large number of free radicals and positive ions, which can act as a powerful oxidizing disinfectant for the air passing through the inside of the circular hole 4 surrounded by metal.

[0025] The positive electrode bracket 5 is connected to the positive electrode of the high-voltage package 2 via an electric wire, and the discharge alloy needle 1 has one end fixedly connected to the inside of the positive electrode bracket 5 and the other end located on the central axis of the circular hole 4 surrounded by metal.

[0026] The discharge alloy needle 1 cooperates with the metal-surrounded circular hole 4 provided inside the negative electrode plate 3 to form a closed zone, and when the tip of the discharge alloy needle 1 discharges, a high-speed rotating corona zone 9 is formed in the middle of the metal-surrounded circular hole 4, effectively increasing the disinfection path for viruses and bacteria and improving disinfection efficiency.

[0027] In some instances, the circular hole 4 is surrounded by metal. center By having the axis overlap with the axis of the discharge alloy needle 1 and the position of the discharge alloy needle 1 on the central axis corresponding to the circular hole 4 surrounded by metal, uniform discharge from the tip of the needle is ensured, ozone generation is suppressed, and in cooperation with the circular hole 4 surrounded by metal, an effective corona zone 9 is formed in the middle of the circular hole 4 surrounded by metal.

[0028] In some examples, multiple insulating connecting posts 6 are provided at intervals on the positive electrode bracket 5, maintaining the negative electrode plate 3 and the positive electrode bracket 5 parallel, and connecting the negative electrode plate 3 and the positive electrode bracket 5 using the insulating connecting posts 6, thereby maintaining a gap of 10 mm or more between the negative electrode plate 3 and the positive electrode bracket 5 and achieving air insulation.

[0029] According to the above technical proposal, the tip of the discharge alloy needle 1 is in a circular hole 4 surrounded by metal. center By discharging at the center of the axis, a corona zone 9 is generated, making it possible to perform air disinfection in environments where people are present. By using the tip of the discharge alloy needle 1 and high-voltage ionization technology to form a rapidly rotating corona zone 9 in the ionization region of the circular hole 4 surrounded by metal, it is possible to perform a powerful oxidation disinfection action on the air flowing from the top of the circular hole 4 surrounded by metal to the bottom of the circular hole 4 surrounded by metal.

[0030] Example 2 Based on Example 1, this example describes the detailed structure of an airborne corona disinfection device based on a circular hole and needle. This example is composed of a high-voltage package 2, a metal-enclosed circular hole 4 provided inside a positive electrode bracket 5, a discharge alloy needle 1 located at the center of the metal-enclosed circular hole 4, and an insulating connecting post 6. The top of the metal-enclosed circular hole 4 is an air inlet 7, and the bottom of the metal-enclosed circular hole 4 is an air outlet 8. Air flows from the inside of the metal-enclosed circular hole 4 toward the positive electrode bracket 5.

S2, the tip of the discharge alloy needle 1 discharges, forming a large number of free radicals and positive ions, which perform powerful oxidative disinfection on the air, and form a rapidly rotating corona zone 9 inside the circular hole 4 surrounded by metal. S3: The positive ions and free radicals emitted from the tip of the discharge alloy needle 1 located inside the circular hole 4 surrounded by metal powerfully oxidize and disinfect viruses passing through the circular hole 4 surrounded by metal, and at the same time, a large number of positive and negative ions are condensed into particulate matter, effectively reducing PM2.5 in the air.

[0033] By adopting the above technical solution, the following effects can be achieved. In the above design, a high-voltage package 2 is used to discharge current from the tip of the discharge alloy needle 1, generating a large number of free radicals and positive ions. These free radicals and positive ions powerfully oxidize and disinfect viruses passing through the circular hole 4 surrounded by metal. The large number of positive and negative ions condense into particulate matter, effectively reducing PM2.5 in the air and suppressing ozone generation. Furthermore, the corona zone formed within the circular hole 4 surrounded by metal by the tip of the alloy needle 1 can be used to effectively disinfect the air.
