Ventilation device used for preventing infectious diseases in public health

Abstract

The invention relates to the technical field of ventilation devices, in particular to a ventilation device used for preventing infectious diseases in public health. The ventilation device used for preventing the infectious diseases in public health comprises an installation frame and a ventilation device body, wherein the ventilation device body is located in an inner cavity of the installation frame, a plurality of flow-guide plates distributed at equal intervals are arranged at the front side of an inner cavity of the ventilation device body, a corresponding rotating rod is arranged at one side of each flow-guide plate in a penetrating mode, one end of each rotating rod is rotatably connected with the ventilation device body, and round rods are arranged at both sides of the inner cavity of the ventilation device body. The ventilation device used for preventing the infectious diseases in public health has the advantages that disassembly is easy, and angles of the flow-guide plates can be automatically adjusted; and in an actual use process, a user can disassemble the ventilation device, and can conveniently clean and maintain the ventilation device, and the angles of the flow-guide plates can be automatically adjusted, so that the practicability of the ventilation device is improved, and the problem that an existing ventilation device cannot be conveniently disassembled by the user is solved.

Description

technical field [0001] The invention relates to the technical field of ventilation devices, in particular to an air ventilation device for public health and prevention of infectious diseases. Background technique [0002] Ventilation is a building environment control technology that uses means such as ventilation dilution or ventilation removal, and generally controls the spread and hazards of air pollutants, and realizes the quality assurance of indoor and outdoor air environments. The ventilation device is to realize the function of ventilation, including air inlets. , exhaust outlet, air supply pipe, fan, cooling and heating, filter, control system and other ancillary equipment, including a complete set of devices. [0003] Public health prevention is a public utility related to the people in a region. A good ventilation device can effectively prevent the spread of pollutants, but the existing ventilation device is not convenient for users to disassemble it, which will af...

AI Technical Summary

Problems solved by technology

[0004] The purpose of the present invention is to provide an air ventilation device for public health and prevention of infectious diseases, which has the advantages of easy disassembly and automatic adjustment of the deflector angle, and solves the problem that the existing ventilation device is inconvenient for users to disassemble it, thus affecting For later cleaning or maintenance of workers, if the installation position of the ventilation device is high, it is inconvenient for the user to adjust the angle of the deflector, which in turn reduces the practicality of the ventilation device
