The invention relates to an automatic sterilization plasma toilet, in particular to a plasma sterilization mechanism for achieving the sterilization effect of the toilet seat surface, so that the toilet seat cushion can be automatically sterilized.

Ordinary toilet seat cushions are many microorganisms that are invisible to the naked eye, and have viruses, bacteria, fungi or parasites that cause infectious diseases. According to the survey conducted by the relevant public health authorities, 32% of the toilet seats have dysentery bacilli, and one of the dysentery bacilli named "Song" has survived on the toilet seat for up to 17 days; another experimental report also It is pointed out that 100 million polioviruses have been put into the toilet, and there are 3,000 viruses on the seat cushion. Toilet seat cushions are easy to adsorb, retain and excrete pollutants, and the possibility of spreading diseases is very high.
