In view of this, the demand for air conditioning sterilization technology is increasing. Although there is also the device that disinfects and disinfect to central air conditioning inside through the ultraviolet lamp at present, because central air conditioning inner structure is changeable, the shape is irregular, has a lot of regions that can not shine when the ultraviolet lamp shines, leads to disinfecting thoroughly, has the bacterium to remain easily, in addition the sterilization efficiency of ultraviolet lamp itself is low, finally leads to the bactericidal effect of ultraviolet lamp in central air conditioning to reach people's anticipated requirement.
In conclusion, the problem of sterilization and disinfection in the central air conditioner has become an urgent technical problem to be solved in the industry.
The invention content is as follows:
in order to make up for the defects of the prior art, the invention provides the central air-conditioning disinfection device based on the pulse light source, which has good sterilization effect, can efficiently kill bacteria and viruses in the air flow of the central air-conditioning, prevents microorganisms such as bacteria and the like from entering the room along with the air-conditioning wind to harm the health of people, and solves the problems in the prior art.
The technical scheme adopted by the invention for solving the technical problems is as follows:
the central air-conditioning disinfection device based on the pulse light source comprises the pulse light source, a filter device, a light beam rectifying device and an airflow guiding device;
