Problems solved by technology
At present, the operation mode of the air valve is basically as follows: the blades rotate and open under the wind force to ventilate and dissipate heat, and when there is no wind, they rotate and droop under the action of gravity to play a protective role. Can not support multi-directional installation

Embodiment Construction
[0022] The following will clearly and completely describe the technical solutions in the embodiments of the present invention with reference to the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only some of the embodiments of the present invention, not all of them. Based on the embodiments of the present invention, all other embodiments obtained by persons of ordinary skill in the art without making creative efforts belong to the protection scope of the present invention.
[0023] It should be noted that when an element is considered to be "connected" to another element, it may be directly connected to the other element or there may be an intervening element at the same time. When an element is referred to as being "disposed on" another element, it can be directly disposed on the other element or intervening elements may also be present.
[0024] Unless otherwise defined, all technical and scientific terms used here...

The invention provides an air valve and a cooling fan. The air valve includes: a frame, the frame includes a central hub, an outer frame sheathed outside the central hub, and a plurality of connecting pieces connecting the central hub and the outer frame, and the outer frame is provided with two Two annular grooves, two annular grooves are respectively located on both sides of the plane where multiple connecting pieces are located; two compression shrapnels, two compressed shrapnels are respectively accommodated in two annular grooves; multiple blades, the number of blades and connecting pieces is equal Consistent, each blade is located between two adjacent connecting pieces, and one end is rotatably connected to the central hub, and the two sides of the other end are rotatably connected to two compression elastic pieces. When each blade is rotated under force, the two compression elastic pieces can be rotated. The distance between them changes; and two cover plates, the two cover plates are respectively located on both sides of the outer frame and can be used to limit the two compressed elastic pieces respectively. The air valve provided by the invention can allow two-way air flow to pass through, and the installation orientation is not limited.
Description
technical field [0001] The invention relates to the technical field of air valves, in particular to an air valve and a cooling fan with the air valve. Background technique [0002] With the rapid development of electronic technology, large-scale network products such as routers, servers and other equipment run faster and faster, and the heat generated during operation also increases accordingly. If effective heat dissipation cannot be carried out, the internal temperature of the device will become higher and higher, which will affect the performance of electronic components and reduce the service life. [0003] In the prior art, a fan is usually used for heat dissipation. In order to prevent dust and other external debris from entering the device through the vent of the fan, an air valve is generally added in front of the fan to play a protective role. At present, the operation mode of the air valve is basically as follows: the blades rotate and open under the wind force to...
