[0002] A fan is a device that converts the kinetic energy of a fluid into mechanical energy and is widely used in industries such as industry, construction, transportation, and environmental protection. The working principle of a fan is to accelerate a fluid (such as air) through rotating blades, thereby creating a pressure differential that causes the fluid to flow. According to the principles of fluid dynamics, the air volume, pressure, and power of a fan are related to factors such as the impeller design, speed, inlet and outlet diameters, and the density of the fluid.

[0003] In the market, many fan products usually rely on manual methods to adjust the wind speed. However, this manual adjustment method sometimes cannot meet the wind speed requirements in specific environments. For example, during the production process, it may be necessary to precisely control the wind speed according to the temperature requirements of different stages. Manual adjustment may not provide the required accuracy and timeliness. Therefore, a device has emerged to adjust the wind speed of the fan according to temperature changes. Utility Model Content

[0024] In order to make the above-mentioned objects, features and advantages of the present invention more obvious and easy to understand, the specific implementation methods of the present invention are described in detail below with reference to the accompanying drawings.

[0025] In the following description, many specific details are set forth to facilitate a full understanding of the present invention. However, the present invention may also be implemented in other ways different from those described herein. Those skilled in the art may make similar generalizations without violating the connotation of the present invention. Therefore, the present invention is not limited to the specific embodiments disclosed below.

[0026] Secondly, the term "one embodiment" or "embodiment" herein refers to a specific feature, structure, or characteristic that may be included in at least one implementation of the present invention. The phrase "in one embodiment" appearing in various places throughout this specification does not necessarily refer to the same embodiment, nor does it refer to a separate or selective embodiment that is mutually exclusive with other embodiments.

[0027] Example 1

[0028] Reference Figure 1 and Figure 4 , is the first embodiment of the present utility model, which provides a device for adjusting the wind force of a fan according to temperature changes, comprising:

[0029] Specifically, the adjustment mechanism 200 includes a shell 201, a fixed shaft 202 is fixedly installed on the outer wall of the shell 201, a gear 204 is connected to the outer wall of the fixed shaft 202 through a bearing, a connecting rod 203 is fixedly installed on the outer wall of the gear 204, a vertical rod 205 is fixedly installed on the outer wall of the connecting rod 203, and a slider 206 is fixedly installed on the outer wall of the vertical rod 205.

[0030] Furthermore, a telescopic mechanism 100 is provided on the left side of the adjusting mechanism 200, and a control mechanism 300 is provided inside the adjusting mechanism 200.

[0031] When in use, the device is connected to the circuit of the fan, the piston in the telescopic mechanism 100 drives the rack 104 to move, and the rack 104 drives the gear 204 to rotate, thereby controlling the movement of the slider 206, controlling the contact between the contact head 311 and the contact slot 310, and thus controlling the speed of the fan.

[0032] In summary, the piston in the telescopic mechanism 100 drives the rack 104 to move, thereby rotating the gear 204, and finally controlling the movement of the slider 206, thereby adjusting the contact between the contact head 311 and the contact slot 310, effectively achieving precise control of the fan speed. This mechanical speed adjustment mechanism has the beneficial effects of rapid response, high reliability, and easy maintenance, and can stably control the working state of the fan under various environments.

[0033] Example 2

[0034] Reference Figure 2 and Figure 3 , which is the second embodiment of the present invention. Different from the previous embodiment, this embodiment provides a telescopic mechanism 100 that expands and contracts according to temperature.

[0035] Specifically, the telescopic mechanism 100 includes a liquid storage tank 101, a tank cover 102 is fixedly connected to the end of the liquid storage tank 101, a liquid storage tank 105 is provided inside the liquid storage tank 101, a rubber ring 107 is movably connected to the inner wall of the liquid storage tank 101, and a piston plate 106 is fixedly connected to the inner wall of the rubber ring 107.

[0036] Furthermore, the piston rod 103 is fixedly connected to the outer wall of the piston plate 106 , and the rack 104 is fixedly connected to the outer wall of the piston rod 103 . The rack 104 is meshed with the gear 204 .

[0037] When in use, add an appropriate amount of ethanol to the liquid storage tank 105. When the temperature rises, the ethanol vaporizes and the volume increases, pushing the piston plate 106 forward. When the temperature drops, the volume of the ethanol decreases, driving the piston plate 106 to move backward. The piston rod 103 pushes the rack 104 to move, and the rack 104 drives the gear 204 to move, thereby controlling the speed of the fan.

[0038] In summary, by utilizing the volatility and expansion properties of liquids, a simple and effective mechanical speed regulation mechanism is implemented without the need for a complex electronic control system, thereby improving the reliability and stability of the system. At the same time, this physical property-based control method reduces energy consumption, lowers maintenance costs, and can maintain efficient fan operation control under various environmental conditions.

[0043] When in use, the adjustment mechanism 200 drives the slider 206 to move, the slider 206 pushes the movable block 309 upward, the contact head 311 connects to the contact slot 310, and the resistor 305 in the path is short-circuited, thereby controlling the current size and achieving the effect of controlling the wind force of the fan.

[0044] In summary, the slider 206 is driven to move by the adjustment mechanism 200, and the slider 206 lifts the movable block 309, so that the contact head 311 contacts the contact slot 310, short-circuiting the resistor 305 in the path, thereby accurately controlling the current size and realizing the adjustment of the wind force of the fan.
