Specifically, the housing 10 may be configured as a cylinder, a prism, or the like, and the housing 10 may be connected to the air hood 201 below. The housing 10 can protect the ultraviolet lamp 30, the ozone generator 40, and other components therein, and can also be used for decoration to make the overall appearance of the purifier 100 more beautiful. The inside of the casing 10 is a hollow structure, and the inside is hollow, that is, the accommodating space 11 can be defined as the hollow inside, and the air duct 20, the ultraviolet lamp 30 and other components can be installed in the accommodating space 11.

The duct 20 may have a cylindrical structure extending along the length of the housing 10. The air duct 20 is hollow inside to form an air flow passage 23 through which air flows. The mounting seat 24 may be disposed outside the wall of the duct 20, and the mounting seat 24 may be integrally formed with the duct 20, or may be fixed on the outer wall of the duct 20 by welding or other methods.

The ultraviolet lamp 30 can emit ultraviolet rays, which can kill viruses, bacteria, etc. in the air.

In one embodiment, the operating principle of the uv lamp 30 may be: the mercury atoms in the lamp tube of the ultraviolet lamp 30 are excited under voltage to produce a characteristic mercury spectral line, and the low-pressure mercury vapor mainly produces 254nm ultraviolet rays. The lamp tube of the ultraviolet lamp 30 is made of ultraviolet-transmitting glass or quartz glass, and ultraviolet rays can be projected through the glass wall. The ultraviolet ray with 254nm wavelength is easy to be absorbed by organism, and acts on the genetic material DNA of organism to promote DNA damage and cause bacteria death, so that the bacteria can be effectively killed. Ultraviolet rays can be concentrated to high intensity to kill bacteria and viruses in a short time, such as escherichia coli and tubercle bacillus, only 0.4 second is needed to kill the bacteria and the viruses, and the ultraviolet sterilization belongs to a pure physical sterilization method and has no secondary pollution.

Meanwhile, the ultraviolet lamp 30 is installed in the inner space of the installation seat 24 and emits ultraviolet light only through the light through hole 241 for sterilization, so that the ultraviolet light can be effectively prevented from leaking, and the ultraviolet radiation is prevented from leaking to the outside and affecting the safety of a user during use.

The ozone generator 40 may be located inside the accommodating space 11 and installed at one end of the air inlet of the air duct 20, and the oil smoke introduced by the fan 202 may flow through the ozone generator 40 first, so as to perform the sterilization and deodorization treatment first under the action of the ozone generator 40. The ozone generator 40 may ionize air by high-voltage ionization to generate ozone to sterilize and deodorize the oil smoke flowing through.

Ozone is a strong oxidizing agent, and can destroy the cell wall of bacteria, diffuse into the cell, oxidize glucose oxidase necessary for the bacteria to oxidize glucose, and act directly on bacteria and viruses, thereby destroying the metabolism and propagation process of bacteria. In addition, ozone can oxidize various odorous inorganic or organic substances, and for example, ozone can decompose odorous gases such as ammonia, benzene, hydrogen sulfide, and the like, thereby performing a deodorizing function. In a word, the time of ozone sterilization, disinfection and deodorization is short, the effect is strong, and the ozone is formed by ionized air so as to remove peculiar smell, thereby obtaining better effect.
