Problems solved by technology
[0003] Common hydrogen peroxide injection methods for plasma sterilizers include: capsule puncture injection method, secondary heating atomization injection method, ultrasonic atomization injection method, etc. The above methods can realize the hydrogen peroxide injection of the sterilizer injection, but the dosage of hydrogen peroxide cannot be controlled. When the dosage of hydrogen peroxide medium added is too small, it may cause incomplete disinfection, cause equipment pollution, and cause serious hazards. If too much hydrogen peroxide medium is added, it will decompose If it is not complete, there will be residual hydrogen peroxide on the surface of the disinfected items, and the residual hydrogen peroxide will cause harm to the user and affect the health of the user

Embodiment Construction
[0021] Fig. 1 is a schematic diagram of a cross-sectional structure of a plasma sterilizer. By describing the structure of the sterilizer, the working principle and specific use method of the sterilizer are illustrated.
[0022] The main structure of the plasma sterilizer is a sterilization chamber 8, which is a cylindrical or rectangular structure. When using the plasma sterilization chamber for sterilization, the articles to be sterilized are placed in the sterilization chamber 8 , the top and bottom of the sterilization chamber 8 are provided with a mesh antenna 1 for exciting plasma, and the connection mesh antenna at the top is fixed on the sterilization chamber 8 through an insulating bracket 5, wherein the mesh The mesh antenna 1 can also be arranged on the opposite inner wall of the sterilization chamber 8 through an insulating support. Plasma can be generated by applying power to the mesh antenna 1 for excitation. The sterilization chamber 8 is connected with multipl...

The invention relates to a method for controlling precise measurement of hydrogen sulfide pulsation injecting liquid through pressure degenerative feedbacks. The method comprises the steps of placing articles to be disinfected in a sterile chamber for disinfection; using a vacuum system to extract vacuum or inflate for the sterile chamber in which the articles to be disinfected are placed; using a plasma generating device to excite the generation of plasmas; using pressure variation signals obtained by a testing control system in the sterile chamber to control a hydrogen peroxide injecting system and determine the dosage of an injected hydrogen peroxide disinfectant, and the injected hydrogen peroxide is excited by the plasmas. Thus, the hydrogen peroxide medium in the plasmas is fully excited, too much or too little injection of the hydrogen peroxide is prevented and precise control of the dosage of the hydrogen sulfide is achieved.
Description
technical field [0001] The invention relates to a sterilizing method for a plasma sterilizer, and more particularly, to a method and a device for controlling the precise metering of hydrogen peroxide pulsating liquid injection through pressure negative feedback. Background technique [0002] Plasma is a special form of matter widely existing in nature (the fourth form other than gaseous, liquid, and solid), a high-energy material aggregation state. There are not only molecules and atoms, but also many charged particles that make up the plasma. The energy of the particles ranges from several eV to several thousand eV. Therefore, it has special physical and chemical properties, and will produce many Special physical and chemical effects. Plasma sterilization technology is a new physical sterilization technology that has emerged in the field of disinfection in recent years. The sterilization technology using hydrogen peroxide plasma as a sterilizing agent has significant advan...
