Detailed Description

The present invention will be described in further detail with reference to the accompanying drawings and specific embodiments.

A control valve comprises a guide groove 20 arranged beside a ventilation opening 10, wherein a baffle plate 30 which can move along the guide groove and can partially or completely shield the ventilation opening is arranged on the guide groove, and the baffle plate is driven by a driving device to move along the guide groove so as to shield or open the ventilation opening.

As shown in fig. 1-2, in the first embodiment, the driving device includes a groove-shaped bracket 310 fixed on the baffle, the opening of which faces the baffle, a rocker 40 extending into the groove-shaped bracket, and one end of the rocker departing from the groove-shaped bracket 310 is hinged to the plane of the vent.

In operation, the rocking bar 40 is toggled to swing around the plane where the rocking bar is hinged 410 to the vent, so that the groove-shaped bracket 310 and the baffle 30 are driven to move along the guide groove 20, and when the baffle 30 is located at the front side of the vent 10, the baffle 30 can shield the vent 10. Utilize the device not only can realize opening and shielding completely of vent 10, thereby can also control the vent size according to external environment control air volume, for example, can reduce the air volume through reducing open-ended size when external wind-force is great to avoid appearing the condition of the unable air inlet of complete closure.

As shown in fig. 3 to 4, in the second embodiment, the driving device includes a pin 320 fixed on the blocking plate 30, a rocker 40 is hinged to the plane where the vent is located, one end of the rocker 40 has a slot 420, the pin passes through the slot 420, and the hinged position of the rocker and the plane where the vent is located at the end away from the slot.

When the air vent is in operation, the rocker 40 is toggled to swing around the plane hinge joint 410 where the rocker and the air vent are located, so that the pin 320 and the baffle 30 are driven to move along the guide groove 20, the pin 320 moves up and down in the slot 420 in the process of moving the baffle, and when the baffle 30 is located on the front side of the air vent 10, the baffle 30 can shield the air vent 10. By utilizing the device, the ventilation opening 10 can be completely opened and shielded, and the opening and closing size can be controlled, so that the air volume can be controlled according to the external environment.
