[0030] In order to enable those skilled in the art to better understand the technical solution of the present invention, the present invention will be further described in detail below in conjunction with the accompanying drawings.

[0031] like Figure 1-4 As shown, a high-efficiency smoke exhaust device comprises a bracket 1 and an air duct arranged on one side of the bracket 1, characterized in that a first fan body 2 and a second fan body 3 which are coaxially assembled are respectively arranged on opposite sides of the bracket 1;

[0032] The second fan body 3 is arranged at the end of the air duct;

[0033] The second sector 3 includes:

[0034] Rotating disk 31;

[0035] Rotating the first fan blade 32 disposed on the rotating disk 31;

[0036] And an elastic member that drives the side surfaces of the plurality of first blades 32 to contact each other.

[0037] Specifically, in the embodiment, the motor 21 driving the first fan body 2 to rotate is located in the base 4, and the rotating disk 31 is rotatably arranged on the base 4. The base is mounted on the cross rod at the center of the bracket 1, such as Figure 2 shown.

[0038] Further, combined with Figure 3 It can be seen that a second slot body 11 is opened on one side of the bracket 1 , and the edge of the first blade 32 is tangent to the inner wall of the second slot body 11 ; and the circumferential radius of the second slot body 11 is greater than the circumferential radius of the first fan body 2 .

[0039] In the above technology, the first fan body 2 is driven to rotate, and the first fan blade 32 is driven to deflect under the drive of wind force, and the second fan body 3 is driven to rotate under the drive of existing wind force and the flow of hot air in the air duct, thereby accelerating the air extraction capacity without increasing energy consumption;

[0040] When the first fan body 2 stops, it recovers under the pulling of the elastic member, so that the plurality of first fan blades 32 rotate and overlap sideways to close the air port.

[0041] As an embodiment further provided by the present invention, Figure 3 and Figure 4It can be known that the elastic member includes an elastic rod body 331 whose first end is arranged on the first end surface of the rotating disk 31 and whose other end is slidably matched with the blade surface of the first blade 32 close to the edge.

[0042] Furthermore, an equidistant spring 332 connected to the protrusion 321 on the first blade 32 is provided on the side of the rotating disk 31 .

[0043] Furthermore, a guide rod 333 slidably matched with the protrusion 321 is fixedly mounted on the outer wall of the rotating disk 31 .

[0044] Specifically, in the above embodiment, when the first fan body 2 stops, the equidistant spring 32 pushes the elastic rod body 331 to Figure 4 The first blades 32 are moved in the direction of the arrow, thereby pulling and causing the first blades 32 to rotate and overlap sideways to close the air port.

[0045] In the embodiment, when the first fan body 2 applies a force to the second fan body 3, the elastic rod body 331 will exert resistance to prevent the first fan blade 32 from opening.

[0046] When the second fan body 3 applies force to the first fan body 2, the elastic rod body 331 will not block it.

[0047] As another embodiment further provided by the present invention, a rubber reinforcement rib 334 is provided on the page of the first fan blade 32 , and the rubber reinforcement rib 334 abuts against the page of an adjacent first fan blade 32 .

[0048] Specifically, when the plurality of first blades 32 rotate and overlap sideways, pressure is applied to deform the rubber reinforcement ribs 334, thereby ensuring that no gap exists after contact.

[0049] As another embodiment further provided by the present invention, the first fan body 2 includes a second fan blade 22, and the second fan blade 22 is arranged obliquely and at a low position close to one side of the second fan body 3.

[0050] Furthermore, the blade surface of the second blade 22 is an arc-shaped structure.

[0051] The above only describes some exemplary embodiments of the present invention by way of illustration. It is undoubted that those skilled in the art can modify the described embodiments in various ways without departing from the spirit and scope of the present invention. Therefore, the above drawings and descriptions are illustrative in nature and should not be construed as limiting the scope of protection of the claims of the present invention.
