Description

Technical Field

[0001] This utility model relates to the field of fan technology, specifically to an electric fan with multiple installation methods. Background Technology

[0002] A fan is a device used to generate airflow for cooling in hot weather. An electric fan is an electrically driven device that produces airflow. The fan inside rotates when powered on, creating a natural breeze to achieve a cooling effect. The main component of an electric fan is an AC motor. Its working principle is that a current-carrying coil rotates due to the force exerted in a magnetic field. The energy conversion is as follows: electrical energy is mainly converted into mechanical energy, but due to the resistance of the coil, some electrical energy is inevitably converted into heat energy.

[0003] Existing clip-on fans for golf carts have a problem with loose clamping; the fan clip easily slips and the fan head falls off when the cart is traveling on bumpy roads. To solve this problem, a new clip structure needs to be designed to address the issues present in existing clip-on fans. Summary of the Invention

[0029] See Figure 1-6 An electric fan with multiple installation methods includes a fan head 1, a support frame 2, and a base 3. The base 3 includes a clamping assembly 31 and a suction cup assembly 32. The clamping assembly 31 includes an upper clamping plate 311, a lower clamping plate 312, and an elastic member 313. The upper clamping plate 311 and the lower clamping plate 312 are elastically connected by the elastic member 313. The lower end face of the upper clamping plate 311 is provided with an upper silicone pad 314, and the upper end face of the lower clamping plate 312 is provided with a lower silicone pad. Pad 315; one end of the suction cup 32 assembly passes through the upper silicone pad 314 and is fixed to the lower end of the upper clamping plate 311 and is located between the upper silicone pad 314 and the lower silicone pad 315; the fan head 1 is movably mounted on the support frame 2, and the end of the support frame 2 is fixed to the upper clamping plate 311; the lower end face of the upper clamping plate 311 is provided with an upper clamping groove 316, and the upper end face of the lower clamping plate 312 is provided with a lower clamping groove 317 corresponding to the upper clamping groove 316.

[0030] In this embodiment, the electric fan incorporates a suction cup 32 assembly and a return strap 33 between the upper clamping plate 311 and the lower clamping plate 312. When the fan is clamped onto the windshield of the golf cart, the suction cup 32 assembly adheres to the glass surface. This allows the suction cup 32 assembly, made of soft rubber, to absorb most of the stress caused by the car's bumps, preventing the fan from moving on the glass. Alternatively, when the clamping assembly 31 is clamped onto the golf cart's shaft, the return strap 33 enhances the clamping force, preventing the fan head 1 from moving and further improving the practicality of the electric fan. The clamping assembly 31 has clamping grooves that match the upper silicone pad 314 and the lower silicone pad 315. By providing anti-slip silicone pads on the clamping assembly 31, the friction between the clamping assembly 31 and the glass surface or rod can be increased, preventing displacement after the clamping assembly 31 is connected to the glass surface or rod. Furthermore, the clamped part has clamping grooves that match the anti-slip silicone pads. When the clamping assembly 31 clamps the clamped part, the silicone pads can be inserted into the clamping grooves, resulting in good connection stability. The suction cup 32 assembly is located within the clamping assembly 31. One side of the suction cup 32 has a pull-up part 321 (for easy lifting of the suction cup 32 to release pressure and open the suction cup 32 and the object being suctioned). When the fan is clamped to the windshield of a golf cart, the suction cup 32 adheres to the glass surface, effectively preventing the fan from moving due to impact.

The open end of the upper clamping plate 311 is provided with a through groove 318 corresponding to the return strap 33. A pull rod 319 is provided in the through groove 318. One end of the return strap 33 can pass through the pull rod 319 in the through groove 318 for fixation.

[0032] In this embodiment, both the upper clamping plate 311 and the lower clamping plate 312 include a clamping part and a pressing part. The outer surface of the upper clamping plate 311 and the outer surface of the pressing part of the lower clamping plate 312 are provided with a plurality of anti-slip protrusions 34, which facilitate the user to forcefully open the clamping assembly 31.

The rotatable angle of the fan head 1 in the U-shaped space is 0° to 360°. By rotating the fan head 1, the angle of the air outlet surface of the fan head 1 can be adjusted. At the same time, the support frame 2 can rotate relative to the base 3 to meet the needs of the user.

[0035] In this embodiment, the fan head 1 includes a fan body and a water spray mechanism. The fan body includes a front air guide net 111, a rear net cover 112, fan blades 113, a drive motor 114, and a control component. The drive motor 114 is fixed inside the rear net cover 112.
