Description

Connection pipe for preventing wind shield from naturally opening and closing to touch air outlet Technical Field The utility model relates to the technical field of exhaust fan connecting pipes, in particular to a connecting pipe for preventing a wind shield from naturally opening and closing to touch an air outlet. Background In the application of the existing ventilation equipment, especially the exhaust fan, the connection pipe is used as an important part for connecting the exhaust fan-out port and the external ventilation pipeline, and the structural design of the connection pipe has important influence on the overall performance and the service life of the equipment. At present, a common connecting pipe is usually provided with a wind shield, the wind shield has the main functions of automatically closing when an exhaust fan stops running, preventing outside air from flowing back into a room, playing a certain roles of dust prevention, insect prevention and the like, and opening when the exhaust fan runs, so that air is smoothly discharged. After the wind shield inside the traditional connecting pipe is opened, the wind shield is easy to collide or rub with the air outlet pipe. Because the wind shield often does not have suitable storage position after opening, the movement track of the wind shield is unreasonable with the position relation of the air outlet pipe, and the wind shield can be blocked inside the air outlet pipe when being naturally opened, and once the wind shield is blocked, a plurality of adverse effects can be generated on the normal operation of the exhaust fan, therefore, the connection pipe for preventing the wind shield from naturally opening and closing and touching the air outlet is provided.
