By means of the structure, air after filtration and drying enters the shell from one end of the ultraviolet lamp tube, flows through the ultraviolet lamp tube along the length direction (the air flows along the length direction, the sterilization time is long, the sterilization effect is good), meanwhile, air in the shell after sterilization and disinfection by the ultraviolet lamp tube enters the ozone generator, ozone is prepared and then enters the shell, and finally the air finally comes out from the air outlet hole and is the air after sterilization and disinfection. The air from the air outlet of the air purifier is sent to the water purifier, so that the air pollution to the purified water in the purified water tower can be eliminated from the source, and the purified water in the purified water tower is ensured not to be polluted. At the same time, the air purifier can also provide sterilized air for any equipment in need.
Further, at least one first partition plate is arranged in the inner cavity of the shell along the length direction of the ultraviolet lamp tube, and the first partition plate is perpendicular to the length direction of the ultraviolet lamp tube.
By means of the structure, air at the tail end of the air circulation path in the shell is sent out for use preferentially, and the sterilizing effect is good.
Further, a plurality of first through holes are formed in the first partition plate.
The first division board separates the shell into a plurality of cavitys, and the intercommunication is passed through first through-hole between the adjacent cavity, provides the route for the air flow direction.
As a preferred form, the housing is a cylinder or a cube.
Preferably, the length direction of the housing is parallel or perpendicular to the horizontal plane.

Since ozone is decomposed over time, the water at the bottom of the water purification tower is easily deactivated by the excessive deposition time. In the prior art, ozone water enters from a purified water inlet and falls into an inner cavity of a purified water tower from the upper part freely, newly injected ozone water cannot be mixed with water deposited at the bottom of the purified water tower, and the water at the bottom of the purified water tower is easy to form dead water to influence water quality. In the invention, the ozone water is introduced into the bottom of the water purifying tower through the guide pipe, and the through groove is arranged to enable the water purifying tower to be injected with the ozone water along the length direction, so that the formation of dead water in the water purifying tower is prevented, and the water quality is ensured.
