Detailed Description
The present invention will be further described with reference to fig. 1 to 3.
The utility model relates to a smoke hood, which comprises a fan.
The utility model relates to a fan, fan include shell 11 and blast gate, and the blast gate includes a plurality of air doors, and each air door is rotationally installed in shell 11, realizes the switching and the adjustment aperture of blast gate through the rotation of each air door, utilizes the switching of blast gate to realize functions such as fire prevention, protection against insects and protection against rodents, and the function of making an uproar falls in the realization rectification through the card of adjustment blast gate. Specifically, one end of the damper is rotatably mounted to one side wall of the housing 11, and the other end of the damper is rotatably mounted to the other side wall of the housing 11.
In some embodiments of the present invention, the air valve includes a driver 13 for driving each air door to rotate, and the driver 13 drives each air door to rotate synchronously. Specifically, the end of each air door is provided with a rocker 14, synchronous rotation of the air doors is realized through a connecting rod 15, and the rocker 14 and the connecting rod 15 are rotatably installed. Further, one end of one of the dampers is mounted to the output end of the driver 13.
The utility model discloses an in some embodiments, be located the rocking arm 14 of each air door with one end and realize the linkage through a connecting rod 15, each rocking arm 14 all rotationally installs with this connecting rod 15 promptly, through the linkage of connecting rod 15, each air door realizes synchronous the rotation.
In some embodiments of the present invention, the rocker arms 14 between two adjacent air doors are connected by a connecting rod 15, i.e. a connecting rod 15 is disposed between every two adjacent rocker arms 14. In some examples, for cost saving, the rocker arms 14 at one end of two adjacent dampers are linked by a connecting rod 15, and the rocker arms 14 at the other end are not provided with the connecting rod 15.
In some embodiments of the present invention, the output end of the driver 13 is provided with a rotatable driving arm 18, and the driving arm 18 is fixedly connected to the end of one of the air doors. The driver 13 drives one of the air doors to rotate, and the other air doors rotate synchronously under the drive of the connecting rod 15.
The utility model discloses an in some embodiments, the air door includes wind blade 12 and wind pivot, and wind blade 12 passes through pin or screw installation in the wind pivot, and the both ends of wind pivot are rotationally installed at the lateral wall of shell 11 respectively, and specifically speaking, the tip at the wind pivot is installed to rocking arm 14. Further, the wind axis of one of the dampers is mounted to the output of the actuator 13.
In some embodiments of the present invention, the housing 11 is provided with a wind wheel 17 and an installation portion 16 for installing the wind wheel 17. Specifically, the mounting portion 16 is mounted on an upper portion of the inner cavity of the housing 11. The mounting portion 16 divides an upper opening of an inner cavity of the housing 11 into left and right openings in which the damper is disposed.
The embodiments of the present invention have been described in detail with reference to the accompanying drawings, but the present invention is not limited to the above embodiments, and various changes can be made without departing from the spirit of the present invention within the knowledge of those skilled in the art.
