Title: Air purifier and water purification system

Description:
FIELD OF THE INVENTION 
     The present invention particularly relates to an air purifier and a water purification system. 
     BACKGROUND OF THE INVENTION 
     In an existing water purification tower, an ultraviolet lamp tube is provided at a top of an inner cavity of the water purification tower, and an ozone inlet and an air inlet are provided at the top of the water purification tower. Filtered and dried air enters the water purification tower via the air inlet, meanwhile, ozone enters the water purification tower via the ozone inlet, and after sterilized by ozone and the ultraviolet lamp tube, the air forms a protective barrier above a water surface of the water purification tower to protect purified water in the water purification tower from being polluted. 
     The existing water purification tower with such a structure cannot ensure that the purified water in the water purification tower is not polluted. The reason lies in that the air entering the water purification tower is not sterilized, i.e. the air entering the water purification tower itself carries harmful substances such as bacteria, and after the air enters the water purification tower, it is most likely to pollute water before the sterilization of the ozone and ultraviolet is exerted. Therefore, the existing water purification tower cannot achieve the effect of protecting the purified water therein from being polluted. 
     SUMMARY OF THE INVENTION 
     The purpose of the present invention is to, in response to the above shortcomings of the prior art, provide an air purifier and a water purification system, which can stop air from polluting purified water in a water purification tower from the source and ensure that the purified water in the water purification tower is not polluted. 
     In order to solve the above technical problems, the technical solution adopted by the present invention is: 
     An air purifier is structurally characterized by including a housing, a vacuum air pump and an ozone generator, at least one ultraviolet lamp tube is provided in the housing, an air inlet is provided at a position of the housing corresponding to one end of the ultraviolet lamp tube, at least one air outlet is provided at a position of the housing corresponding to the other end of the ultraviolet lamp tube, and an air filter unit is communicated with the air inlet by means of an air drying unit; and an air inlet end of the vacuum air pump is communicated with an inner cavity of the housing, an air outlet end of the vacuum air pump is communicated with an air inlet end of the ozone generator, and an air outlet end of the ozone generator is communicated with the inner cavity of the housing. 
     With the above structure, filtered and dried air enters the housing from one end of the ultraviolet lamp tube and flows through the ultraviolet lamp tube along the length direction (since the air flows along the length direction, the sterilization time is long and the sterilization effect is good), meanwhile, the air sterilized by the ultraviolet lamp tube in the housing enters the ozone generator, the produced ozone enters the housing, and the sterilized air finally flows out of the air outlet. The air flowing out of the air outlet of the air purifier is delivered to a water purifier, which can stop the air from polluting purified water in the water purification tower from the source and ensure that the purified water in the water purification tower is not polluted. In addition, the air purifier can also provide the sterilized air for any device in demand. 
     Further, at least one first division plate is provided in the inner cavity of the housing and is along the length direction of the ultraviolet lamp tube, and the first division plate is perpendicular to the length direction of the ultraviolet lamp tube. 
     With the above structure, the air at the tail end of the air flow path in the housing is preferentially delivered out for use, with good sterilization effect. 
     Further, the first division plate is provided with one or more first through holes. 
     At least one first division plate divides the housing into one or more cavities, and the adjacent cavities are communicated with each other through the first through hole to provide a path for air flow. 
     As a preferred mode, the housing is cylindrical or cubic. 
     As a preferred mode, the length direction of the housing is parallel to or perpendicular to the horizontal plane. 
     Based on the same inventive concept, the present invention further provides a water purification system, which includes a water purification tower and further includes the air purifier, and one air outlet of the air purifier is communicated with an inner cavity of the water purification tower. 
     Further, an air duct is provided in the inner cavity of the water purification tower, the air outlet is communicated with one end of the air duct, and the other end of the air duct is provided with a sand air-diffuser. 
     The sterilized air provided by the air purifier is injected into purified water through the sand air-diffuser to sterilize the purified water. 
     Further, a diversion pipe is provided in the inner cavity of the water purification tower, a top of the water purification tower is provided with a purified water inlet, the purified water inlet is communicated with one end of the diversion pipe, the other end of the diversion pipe extends to a bottom of the water purification tower, and a side wall of the diversion pipe is provided with a through slot along the length direction. 
     Since ozone is decomposed over time, the water at the bottom of the water purification tower is prone to deactivation due to long-time deposition. In the prior art, ozone water enters from the purified water inlet and freely falls into the inner cavity of the water purification tower from above, the newly injected ozone water is not mixed with the water deposited at the bottom of the water purification tower, and the water at the bottom of the water purification tower easily forms dead water to affect water quality. In the present invention, the diversion pipe introduces ozone water to the bottom of the water purification tower, and the ozone water is injected throughout the water purification tower along the length direction by means of the through slot, thereby preventing the formation of dead water in the water purification tower and ensuring water quality. 
     Further, at least one second division plate is provided in the inner cavity of the water purification tower and is along the length direction of the water purification tower, and the second division plate is perpendicular to the length direction of the water purification tower. 
     With the above structure, the purified air at the tail end of the purified air flow path in the housing is preferentially delivered out for use, which further prevents the formation of dead water and further ensures water quality. 
     Further, the second division plate is provided with one or more second through holes. At least one second division plate divides the water purification tower into one or more cavities, and the adjacent cavities are communicated with each other through the second through hole to provide a path for purified water and air flow. 
     Compared with the prior art, the present invention can stop air from polluting purified water in the water purification tower from the source, ensure that the purified water in the water purification tower is not polluted, prevent the formation of dead water in the water purification tower, and ensure water quality.
