Description

Technical Field

[0001] The present invention relates to the technical field of antibacterial equipment, and specifically to a main control system and method for a pulsed low-frequency electromagnetic field antibacterial chamber. Background Art

[0002] Antibacterial chamber treatment refers to a comprehensive operation in which the item to be treated is sent into a closed space by a special device, and then the item is sterilized and disinfected by ultraviolet light or other physical means. Antibacterial chamber treatment is mainly used in places such as catering, hotels, and medical care, as well as in production and processing links such as electrical appliances and textiles. It can effectively kill or reduce the growth and reproduction of harmful microorganisms such as bacteria and viruses, thereby ensuring the hygiene, health, and quality safety of the item.

[0003] Existing antibacterial chambers usually generate an electromagnetic field inside them to sterilize items. During use, as the magnetic field strength or the number of pulses increases, the number of bacteria residues will reach a trough value, and the sterilization effect is the best at this time. After that, as the magnetic field strength or the number of pulses further increases, the sterilization effect becomes worse instead. After the number of bacteria residues reaches a peak value, the sterilization effect becomes good again. Therefore, there is an urgent need to propose a system that can control the electromagnetic field strength. Summary of the Invention
