Two-band ultraviolet multifunctional sterilizing purifier

The disclosed UV-ray multifunctional sterilization purification machine comprises: two UV lamp tubes with 253.7nm and 184.5nm wavelengths, a quartz tube, a stainless steel shell, a sterilization purification device with stainless steel baffle board and cap connected to a fan to provide cycle power for air, a pump to provide cycle power for water, a Venturi tube and a water storage tank. Wherein, the UV ray radiates the gas n chamber then the liquid in through the quartz wall to sterilize and purify to gas and liquid simultaneously; the ozone form 184.5nm UV ray can also be absorbed in Venturi tube for further sterilization and purification. This invention has variable sterilization purification modes for different requests.
