Problems solved by technology

[0003] The circlip is not a memory alloy material, and it cannot be deformed by the heat generated by the rotation during the high-speed rotation of the fan, and cannot drive the fan blades to open. Changing the radian of the fan blades cannot change the generated air volume, which is not very practical

Embodiment Construction

[0025] The present invention will now be further described in detail in conjunction with the accompanying drawings and embodiments. These drawings are all simplified schematic diagrams, only illustrating the basic structure of the present invention in a schematic manner, so it only shows the composition related to the present invention.

[0026] Such as figure 1 , figure 2 with image 3 As shown, the fan capable of opening and closing the fan blades 21 through rotation includes: a body 10 , a plurality of fan blades 21 and a retaining spring 20 .

[0027] Specifically, a plurality of fan blades 21 are arranged at intervals in the outer circumferential direction of the machine body 10, and the fan blades 21 are flexible parts. A plurality of cavities 23 are arranged inside the fan blades 21, and fluid is arranged inside the plurality of cavities 23. The cavities 23 There is at least one blocking valve 22 inside, and the circlip 20 is used to connect the body 10 and the tail ...

Abstract

The invention discloses a fan capable of conducting fan blade opening and closing through rotation. The fan comprises a machine body and snap springs. A plurality of fan blades are arranged on the outer side of the machine body in the circumferential direction at intervals. The fan blades are flexible pieces. A plurality of cavities are formed in the fan blades. Fluid is arranged in the multiple cavities. At least one stop valve is arranged in each cavity. The snap springs are used for connecting the machine body with the tails of the fan blades. The snap springs are memory alloy materials. The snap springs deform in the high-speed rotation process of the fan, and the snap springs can drive the fan blades to be opened and closed. The fan rotates at the high speed, the snap springs deform along with temperature rise of the fan, the fan blades are driven to be opened, the fluid in the various cavities is different in volume, and the bending angle of the fan blades can be adjusted. Afterthe stop valves are closed, the pressure in the cavities is not uniform, radian is generated to the fan blades, accordingly, the air volume of the fan can be flexibly changed, and flexibility is high.

Description

technical field [0001] The invention relates to a fan, in particular to a fan capable of opening and closing fan blades through rotation. Background technique [0002] A fan refers to a tool used to generate wind to keep cool in hot weather. An electric fan is a device that is driven by electricity to generate air flow. The fan inside is powered on and then rotates into natural wind to achieve the effect of cooling. The wingless fan does not compress the air. The principle is similar. For the wing of an airplane, the wall thickness of the upper ring is not uniform, that is to say, one side of the ring has a larger diameter and the other side is relatively smaller, so that the air blown from the bottom will weaken the surrounding air after passing through the ring. Air pressure, thereby driving the surrounding air and enhancing air flow. [0003] The circlip is not a memory alloy material, and it cannot be deformed by the heat generated by the rotation during the high-speed ...
