Of course, in the present embodiment, the first preset concentration is not limited to 400/cm 3 The user can set the value of the first preset concentration by himself, and the user can set the value of the first preset concentration according to personal habit, preference, physical health condition and other factors. Illustratively, some users have poor immunity and the user with frequent headache can set the first preset concentration to 1000 pieces/cm 3 Or a larger value.
