A top ventilation structure for building structure

Abstract

The invention discloses a ventilation structure on the top of a building structure, which relates to the technical field of building ventilation. The structure comprises a building main body, wherein the top of the building main body is fixedly connected to a bottom plate. The ventilation structure on the top of the building structure is provided with a partition, a disinfection chamber and an air pipe. External air is blown into the disinfection chamber, so that the air pushes the fan blades to rotate, so that the fan blades drive the transmission rod to rotate, so that the cam rotates. When the circular surface end of the cam rotates toward the pressure block, the connecting spring pushes the pressure block to drive the piston rod to move upward. The liquid inside the fourth servo motor is sucked into the piston cylinder through the connecting pipe and the connecting head. When the convex surface end of the cam rotates toward the pressure block, the pressure block pushes the piston rod to move downward. The liquid inside the piston cylinder enters the partition through the connecting head, the connecting pipe and the fixed pipe, and is sprayed out through the atomizing nozzle. The air contacts the atomized disinfectant to be disinfected, thereby being able to disinfect and sterilize the air and protect the health of people inside the building structure.

Description

Technical Field

[0001] The invention relates to the technical field of building ventilation, in particular to a ventilation structure on the top of a building structure. Background Art

[0002] The commonly used building ventilation system solution is to add windows to the outer wall of each floor of the building, but this will allow various dust and impurities from the outside to enter the room, and various noises and mosquitoes will also enter the room, affecting various normal activities in the room. In addition, central air conditioning will be added indoors to meet the needs of the indoor ventilation environment, but this requires a lot of electricity, which is contrary to today's green energy-saving concept. Therefore, more and more buildings choose top ventilation structures. According to an energy-saving building top ventilation structure with application number CN211739411U, it has the function of outdoor air entering the ventilation skylight from the baffle under the action of a fan. When passing through the filter device, the suspended particulate matter in the air is removed by the filter layer, and then the toxic substances are adsorbed by the activated carbon layer. At the same time, the ultraviolet lamp sterilizes the filtered air. This application uses ultraviolet rays to sterilize the air, but the time required for ultraviolet rays to sterilize the air is relatively long, which affects the ventilation efficiency of the structure.
