In the purifier 100 according to the embodiment of the present application, the air flow may first be sterilized and deodorized by the ozone generator 40 and then flows into the fixing base 20, and then is further sterilized and decomposed by the ultraviolet lamp 30, so that the air flow discharged from the purifier 100 is cleaner and cleaner. Ultraviolet lamp 30 installs and jets out the ultraviolet ray through logical unthreaded hole 22 in fixing base 20, and the upper and lower below of fixing base 20 all is provided with the light screen simultaneously, and then can effectively prevent the ultraviolet ray to leak, avoids causing ultraviolet radiation for clarifier 100 is safe and reliable more when using, promotes user's use and experiences.

Specifically, the housing 10 may be configured as a cylinder, a prism, or the like, and the housing 10 may be connected to the lower wind cover 201. The housing 10 can protect the ultraviolet lamp 30, the ozone generator 40, and other elements therein, and can also be used as a 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, i.e. the accommodating space 11 can be defined, and the parts such as the air duct pipe and the ultraviolet lamp 30 can be installed in the accommodating space 11.

The fixing base 20 may be configured as an annular block structure with an air flow channel 21 formed at a central position, the air flow channel 21 extends along the length direction of the housing 10, and the fixing base 20 is transversely disposed at a middle position of the accommodating space 11. Two sides of the air channel 21 on the fixing base 20 are provided with a hollow mounting cavity 23, and the ultraviolet lamp 30 can be fixed in the mounting cavity 23.

As shown in fig. 3 and 4, a light passing hole 22 may be formed between the installation cavity 23 and the central air flow passage 21, and light emitted from the ultraviolet lamp 30 may be emitted through the light passing hole 22.

Meanwhile, the fixing base 20 may be made of a material for shielding ultraviolet rays. Ultraviolet lamp 30 installs in installation cavity 23 and carries out the degerming through logical unthreaded hole 22 transmission ultraviolet ray, can effectively prevent that the ultraviolet ray from leaking, avoids ultraviolet radiation to leak to the outside, security when influence user uses.

Wherein, the operating principle of the ultraviolet lamp 30 can be: the mercury atoms in the lamp tube of the uv lamp 30 are excited under voltage to produce a characteristic spectrum of mercury, and the low pressure mercury vapor produces primarily nm uv radiation. The lamp tube of the ultraviolet lamp 30 is made of ultraviolet-transparent glass or quartz glass, and ultraviolet rays can be projected through the glass wall. The ultraviolet ray with the wavelength of nm is easily absorbed by organisms, acts on genetic material DNA of the organisms, promotes the DNA to be damaged to cause the death of bacteria, and can effectively kill the bacteria. 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.

The ozone generator 40 may be disposed in the accommodating space 11 and below the fixing base 20, and the ozone generator 40 may generate ozone. Ozone is a strong oxidant, can destroy the cell walls of decomposing bacteria, so as to diffuse into the cell and oxidize glucose oxidase necessary for decomposing bacteria to oxidize glucose, and can also directly react with bacteria and viruses, so as to destroy the metabolism and the propagation process of the bacteria. In addition, ozone can oxidize various odorous inorganic or organic substances, and for example, ozone can decompose odorous gases such as ammonia, benzene, and hydrogen sulfide, thereby performing a deodorizing function. In a word, the time of ozone sterilization, disinfection and deodorization is short, the effect is strong, and the ionized air is utilized to form ozone so as to remove peculiar smell, so that a better effect can be achieved.

The air flow guided into the accommodating space 11 by the fan 202 flows through the ozone generator 40 to perform deodorization and sterilization, and then performs ultraviolet sterilization, so that the sterilization effect of the purifier 100 is better. Meanwhile, because the ultraviolet rays can also accelerate the digestion rate of ozone and improve the oxidation capacity, when the airflow is subjected to high-pressure ionization for deodorization by the ozone generator 40, the gas with ozone continues to flow upwards, the mixed gas effectively destroys the molecular structure of organic matters and finally decomposes the ozone under the synergistic action of the ultraviolet rays due to the formation of hydroxyl radicals, and the gas after decomposing the ozone is discharged indoors or outdoors, so that the environment pollution or the influence on the health of users caused by the discharge of the ozone along with the airflow is avoided.

As shown in fig. 4, the upper light shielding plate 91 and the lower light shielding plate 92 are disposed in the accommodating space 11, and have shapes adapted to the shape of the accommodating space 11 at the corresponding mounting positions.
