Handheld plasma body disinfection flashlight

Abstract

The invention relates to a flashlight which can be carried on a person and used in the disinfection field, in particular to a handheld plasma body disinfection flashlight. The handheld plasma body disinfection flashlight comprises a charger module, a switch, an oscillation module, a voltage boosting module, a centrifugal fan and electrodes. The charger module comprises a rechargeable battery and a voltage reducing and rectifying circuit. Direct current voltage supplied by the rechargeable battery passes through the oscillation module and then is output as low-voltage alternating current, and the voltage and the frequency of the low-voltage alternating current are adjustable. The low-voltage alternating current passes through the voltage boosting module to be raised to high-voltage alternating current which generates plasma body 'flames' between the electrodes. The handheld plasma body disinfection flashlight further comprises the centrifugal fan which is arranged at the front end of the electrodes. Compared with traditional plasma body disinfection equipment, the size of the handheld plasma body disinfection flashlight is greatly reduced, an air supply device is not needed, and the handheld plasma body disinfection flashlight is convenient to carry and good in disinfection effect. The handheld plasma body disinfection flashlight can be used not only for an ambulance, rescue in natural disaster, a military strike action and treatment in a remote area, but also in the hygienic material industry, the paper-making industry, the food industry, the tableware industry and other industries which need disinfection.

Description

technical field [0001] The invention relates to a portable flashlight used in the field of disinfection, that is, a hand-held plasma disinfection flashlight, which can be used for disinfection and sterilization in hospitals, enterprises, schools and individuals. Background technique [0002] Hospitals have always attached importance to disinfection and sterilization, but they have not been able to find a method for thorough sterilization, and it is even more difficult to sterilize in public places. In 1987, J.S.Clements proposed high-voltage pulse discharge plasma technology, and studied the phenomenon of gas being pre-breakdown during the discharge process. Since then, scholars from various countries have conducted in-depth research on this and applied plasma technology to the field of disinfection. [0003] Traditional plasma disinfection equipment requires external power supply and gas supply equipment, which is inconvenient to carry, which limits the application of plas...

Problems solved by technology

[0004] There are 8 domestic invention patents related to plasma disinfection, 29 utility model patents, and 1 appearance patent, including plasma disinfection devices, plasma disinfection and sterilization shoe cabinets and cabinet-type plasma disinfection air purifiers. So far, Patents related to handheld plasma disinfection have not yet appeared

However, the traditional plasma disinfection equipment is bulky and requires external AC and gas supply equipment. These shortcomings limit the application of plasma disinfection equipment in ambulances, natural disaster rescue, military strike operations and treatment in remote areas
