The lamp 3 can generate a pulse flash with a wavelength of 200-1100 nm, and simultaneously acts on the first and second chambers 1211 and 1212 to efficiently sterilize them. The action mechanism of the pulse flash sterilization is the synergistic action of all wave bands in a spectral range, and is mainly embodied in three aspects:

(1) photochemical reaction in ultraviolet band: when the microorganism is irradiated by ultraviolet light in the pulsed intense light spectrum, thymine and cytosine in nucleic acid substances (DNA and RNA) generate photochemical reaction to generate dimers, so that the nucleic acid substances of the microorganism are damaged);

(2) flash heating effect: when the peak power per cm2 area reaches more than 1000W, the microorganism is heated to more than 100 ℃, and the microorganism can not be cooled normally due to extremely short flash irradiation time, so that cell walls are broken and melted to die;

(3) pulse effect: the penetration of the intense pulsed light and the transient high energy mechanical impact damage the cell walls and other cellular components, resulting in bacterial death.

In addition, the spectrum range of the pulse flash covers ultraviolet, visible light and infrared light parts, the ultraviolet wave band and ozone generated by 185nm ultraviolet, the pulse flash has strong oxidizability, and plastic tableware is irradiated by the ultraviolet for a long time, so that the risk of aging and powdering exists.
