Description

Technical Field

[0001] This utility model relates to the field of plasma generator manufacturing technology, specifically to a small integrated plasma generator. Background Technology

[0002] The main working principle is to boost the low voltage to positive and negative high voltage through a boost circuit. The positive and negative high voltages are used to ionize the air and generate a large number of positive and negative ions. The number of negative ions is greater than the number of positive ions, which can be used for sterilization and deodorization.

[0003] According to invention patent application CN107124815B, published on October 31, 2023, a plasma generator is disclosed, including an anode and a cathode. The anode is a tubular body with its axis arranged along the front-rear direction. The hollow portion of the tubular body forms a plasma arc generating cavity. A cooling gas cavity is disposed on the outer periphery of the anode, and the cooling gas cavity has a first inlet for introducing compressed gas. The cathode is located at the front end of the anode and opposite to the plasma arc generating cavity. A medium gas cavity communicating with the plasma arc generating cavity is disposed on the outer periphery of the cathode, and the medium gas cavity has a second inlet for introducing medium gas. Multiple guide holes are formed on the sidewall of the anode, connecting the cooling gas cavity and the plasma arc generating cavity. The multiple guide holes are configured such that the compressed gas entering the plasma arc generating cavity through the guide holes forms a wall-attached swirling gas film with tangential velocity and rearward axial velocity. Its main technical effect is that it simultaneously achieves anode cooling and arc stabilization functions using compressed gas.

To address this issue, a small integrated plasma generator is proposed to solve the problem of the large size of existing plasma generators. Utility Model Content
