Detailed Description

In order to better understand the purpose, structure and function of the present invention, the following description is made in detail with reference to the accompanying drawings.

The utility model discloses a range hood, including the casing, the casing is opened there is the air intake, and through the drive of fan, the oil smoke gets into the spiral case in the casing from the air intake to carry out the oil smoke wind and leave.

As shown in fig. 1 to 3, in order to prevent the backflow phenomenon, the air inlet is provided with a fixing frame 1 on the inner walls of both sides, and an air door assembly is mounted on the fixing frame 1. The damper assembly includes a damper body 2 and a drive mechanism. The driving mechanism is installed on the inner wall of the air inlet, and the air door body 2 is installed on the driving mechanism. When the driving mechanism drives the air door body 2 to move upwards, the air inlet is opened by the air door body 2; after actuating mechanism drives air door body 2 and resets, air door body 2 seals the air inlet.

The driving mechanism comprises a rotating arm group and a driver 7, wherein the rotating arm group comprises two rotating arms of a driving arm 3 and a driven arm 4; the driving arm 3 and the driven arm 4 are equal in length, are arranged from top to bottom one by one and are parallel to each other. The rotating arm is far away from one end of the air door body 2 and is hinged with the inner wall of the air inlet. The lower end of the back of the air door body 2 is provided with a fixed seat 5, and the fixed seats 5 are hinged with the rotating arms one by one; thereby the swinging boom all is being close to 2 one ends of air door body, and is articulated with 2 backs of air door body. The driver 7 drives the driving arm 3 to swing, and the driven arm 4 swings accordingly, so that the air door body 2 moves upwards.

In order to guarantee that air door body 2 reciprocates stably, air intake inner wall both sides respectively are equipped with a set of rotating arm group, and through two sets of rotating arm groups that the symmetry set up, drive air door body 2 removal jointly. In order to ensure that the two groups of rotating arm groups move synchronously, a connecting rod 6 is arranged between the driving arms 3 of the two groups of rotating arm groups, and two ends of the connecting rod 6 are fixedly connected with the two driving arms 3 respectively, so that the two groups of rotating arm groups can be driven to rotate synchronously by a driver 7.

The driver 7 can be a synchronous motor, and because the connecting rod 6 is arranged along the rotating axis of the driving arm 3, the output shaft of the driver 7 and the connecting rod 6 are coaxially fixed to drive the driving arm 3 to rotate and drive the air door body 2 to move up and down. The driver 7 can also be a microswitch or a plectrum which drives the air door body 2 to move up and down.

Like this through actuating mechanism, move air door body 2 and shift up, other modes such as not moving down have prevented that air door body 2 from taking place to interfere with higher pan limitedly, and required removal space is less moreover, reduces the oppression sense in the vision.

It is to be understood that the present invention has been described with reference to certain embodiments, and that various changes or equivalents may be substituted for elements thereof by those skilled in the art without departing from the spirit and scope of the invention. In addition, many modifications may be made to adapt a particular situation or material to the teachings of the invention without departing from the essential scope thereof. Therefore, the present invention is not limited to the specific embodiments disclosed herein, and all embodiments falling within the scope of the claims of the present application are intended to be covered by the present invention.
