The electric shaver has no net cover, does the blade fall off?

Fall down. The mesh cover of the electric shaver is mainly used to protect the cutter head from falling off and limit the scraping depth of the cutter head, so the electric shaver has no mesh cover and the cutter head falls off. An electric shaver is a device for shaving. It was first introduced in the United States in 1930, and JacobSchick applied for the first patent of electric shaver.
