As shown in fig. 1 to 2, when assembled, the filter screen 310 is inserted into the receiving cavity inside the case 200 through the first mounting hole 230 on the front sidewall of the case 200; the first mounting plate 320 covers the first mounting hole 230 and is detachably connected to the front sidewall of the case 200; the ultraviolet lamp 410 and the negative ion generator 420 are inserted into the accommodating cavity inside the box body 200 through the second mounting hole 430 on the front side wall of the box body 200 in the left-to-right direction; the second installation plate 430 covers the second installation hole 240 and is detachably coupled to the front sidewall of the case 200.
In this embodiment, the detachable connection is a threaded connection.
As shown in fig. 2, a box handle 250 is installed on the upper sidewall of the box 200 to facilitate the taking and placing of the box 200; a first handle 321 is arranged on the first mounting plate 320 at the side opposite to the filter screen 310, so that the filter screen assembly 300 can be conveniently taken and placed; the second mounting plate 430 is provided with second handles 431 at the left and right ends of the side opposite to the ultraviolet lamp 410 and the anion generator 420, respectively, so as to facilitate the taking and placing of the ultraviolet lamp and the anion generator assembly 400.

In this embodiment, the filter screen 310 is a blended air filter screen of nano silver wires and foam or sponge, and the nano silver wires have strong inhibition and killing effects on dozens of pathogenic microorganisms such as escherichia coli, gonococcus, chlamydia trachomatis and the like, do not generate drug resistance, can effectively reduce and control the breeding of bacteria, and can play a role in resisting bacteria and removing bacteria.
In the present embodiment, the ultraviolet lamp 410 is a type of light source that can generate ultraviolet light over a wide effective range. The ultraviolet lamp 410 emits ultraviolet rays with a wavelength of 240-280 nm, which most kill and destroy the molecular structure of DNA (deoxyribonucleic acid) or RNA (ribonucleic acid) in bacteria and viruses, so that the growth cell death and/or the regenerative cell death are/is caused, and the sterilization and disinfection effects are achieved, particularly, the ultraviolet rays with the wavelength of 253.7 have the strongest sterilization effect. When organic pollutants pass through an ultraviolet irradiation area, ultraviolet rays penetrate cell membranes and cell nuclei of organisms, are absorbed by base pairs of DNA or RNA, and generate photochemical action, so that genetic materials of cells are changed, the activity of the genetic materials of the cells is lost, and microorganisms cannot reproduce or die in a short time. At the same time, ultraviolet rays destroy the regeneration ability of organisms.
In this embodiment, the ultraviolet lamp 410 generates two ultraviolet light waves of UVC and UVV, wherein the UVC wavelength is 254nm, which has good bactericidal properties, can destroy DNA of microorganisms, and can penetrate bacterial membranes, break DNA structures of microorganisms, and inhibit propagation of microorganisms.

Since the gas discharged from the gas outlet enters the cavity inside the box 200 through the gas inlet 210 and is discharged through the gas outlet 220, the irradiation time is related to the cavity inside the box 200 and the volume of the box 200; the larger the volume of the chamber 200, the longer the irradiation time.
