Abstract

The invention discloses a cold plasma generating device which does not generate ozone. The device comprises a ceramic sheet, an air chamber, an air pump, a one-way airflow conduction nozzle and a high-voltage power supply, wherein the ceramic sheet is positioned in the air chamber; one side of the air chamber is connected with the air pump through a glass ventilation pipe, and the other side of the air chamber is connected with the one-way airflow conduction nozzle through a glass ventilation pipe; the high-voltage power supply is connected with the ceramic sheet through a high-voltage electrode and a ground electrode respectively. The plasma which hardly contains ozone can be stably generated, and the damage to the human body caused by long-time exposure to ozone with the standard concentration is avoided.

Description

technical field [0001] The disclosure belongs to the field of plasma applications, and in particular relates to a cold plasma generator that does not generate ozone. Background technique [0002] At present, the common generation methods of atmospheric pressure cooling plasma mainly include surface dielectric barrier discharge and jet discharge. Surface dielectric barrier discharge can generate large area and uniform plasma. However, in the process of surface dielectric barrier discharge, a very high concentration of ozone will be produced, which will cause considerable damage to human health. Especially for long-term use of discharge devices, it will cause damage in the following aspects: 1. Strongly stimulate the human respiratory tract, causing sore throat, chest tightness and cough, causing bronchitis and emphysema; 2. Can cause human neurotoxicity , dizziness, headache, vision loss, and memory loss; 3. It will destroy the vitamin E in human skin, causing human skin to...
