Exhaust fans are a common household appliance for exhausting polluted air in a room or a building to improve indoor air quality. They are typically mounted on a wall, ceiling or window and generate a wind flow by rotation of a fan to expel air from the room. Exhaust fans play a vital role in residential environments, kitchens, bathrooms and other places where ventilation is required.
Conventional exhaust fans are typically comprised of a housing, a fan blade, a motor, and a motor mount. On the back of the exhaust fan, back plates are usually installed, and function of the back plates is to be opened when the exhaust fan is opened for exhaust and closed when the exhaust fan is closed to prevent dust, rainwater or foreign matter of the external environment from entering. The opening and closing of the backboard is usually controlled by one or more movable rods, and when the exhaust fan is opened, the movable rods are driven by wind power to move the backboard to open so as to facilitate exhaust; when the exhaust fan is closed, the movable rod moves the backboard to be closed under the action of gravity.
However, as time passes and the frequency of use increases, the back plate is susceptible to dirt such as dust, oil stains, etc., resulting in the back plate being prevented from opening or closing. This not only reduces the exhaust efficiency of the exhaust fan, but may also affect its service life. Therefore, it is necessary to provide a powerful exhaust fan, which can ensure that the back plate is completely opened when the exhaust fan is opened, and can be effectively closed when the exhaust fan is closed, and can adapt to different numbers of back plates to meet different exhaust requirements.
