Background

The ventilation fan is widely applied to thousands of households as a necessary product in daily life. The present ventilator is an air-conditioning electric appliance, in which the fan blades are driven by a motor to rotate channel air flow so as to exchange indoor air and outdoor air. The ventilator may be used to remove indoor air and introduce outdoor air. The ventilating fan is widely applied to families and public places. For example, in a toilet which is a common place for home use, it is necessary to exhaust air from the toilet during bathing, and indoor and outdoor ventilation of the toilet can be achieved by using a ventilation fan.

At present, the traditional ventilator baffle switch structure mainly realizes the opening or closing of the baffle by a control mode of knotting on a pull rope. The existing ventilator baffle switch structure mainly controls the opening or closing of the baffle in a mode that a rope knot is clamped on a frame body clamping groove, when a rope is pulled, the rope needs to be pulled by being inclined to one side with a large groove position, the rope knot is straightened again after passing through the rope knot, and the control mode is unreliable. If the oblique pull is not in time, the knot (opening or closing the knot) of required control can be skipped in the time of returning to straight, resulting in the switch unreliable, customer experience feels poor, has the risk of breaking away from when the knot incompletely gets into the draw-in groove (for example, when only half or one-third knot gets into the draw-in groove), and the stay cord often swings left and right in addition and draws easy wearing and tearing to lead to disconnected rope to one side.
