Description

Technical Field

[0001] This utility model relates to the field of folding electric fan technology, and in particular to a portable folding electric fan. Background Technology

[0002] As people's living standards improve, their demands for electric fans have gone beyond just the basic function of blowing air. They now crave lightweight, compact, multifunctional fans suitable for various scenarios. Against this market backdrop, a new type of electric fan has emerged, featuring extendable height, folding design, oscillation, and lightweight construction. This new fan represents a significant design breakthrough compared to similar products, further optimizing the manufacturing process.

[0003] Existing telescopic poles are typically secured by inserting a plastic sheet inside the aluminum alloy telescopic pole and then screwing it in from the outer telescopic pole sleeve. This method is complex and requires considerable time and tools for both installation and disassembly. Utility Model Content

[0004] To solve the above-mentioned technical problems, this utility model provides a portable folding electric fan.

[0005] This utility model is achieved using the following technical solution: a portable folding electric fan, including a foldable fan head, a telescopic rod sleeve at the bottom of the foldable fan head, a telescopic rod installed inside the telescopic rod sleeve, the bottom end of the telescopic rod being engaged with the inside of the telescopic rod sleeve by a pin, the pin including a barb, a beveled head, a cavity, a pin body and a pin head, two barbs being provided, beveled heads being provided on the surfaces of the two barbs, two beveled heads being provided, a pin body being fixedly connected to the rear ends of the two barbs, a cavity being provided at the ends of the two barbs that are close to each other, and a pin head being fixedly connected to the rear ends of the pin body.

[0006] Through the above technical solution, the barb serves to hold the telescopic pole sleeve in place, preventing the pin from falling off after installation and ensuring that the pin is firmly fixed inside the telescopic pole sleeve, providing stable support for the telescopic pole. The beveled head acts as a guide during pin installation, allowing the pin to be smoothly inserted into the telescopic pole sleeve, reducing resistance and difficulty during installation and improving installation efficiency. The cavity is a clearance position for the beveled head to deform inward during perforation installation, providing space for the deformation of the beveled head, allowing the pin to be smoothly inserted into the telescopic pole sleeve without being jammed due to the deformation of the beveled head. The pin body is the force-bearing body of the pin, bearing the main fixing function and able to withstand various forces generated during the use of the telescopic pole, ensuring the stable fixation of the telescopic pole. The pin head's function is to hold the pin in place, preventing it from falling into the hole of the telescopic pole sleeve after installation, ensuring that the pin is firmly fixed inside the telescopic pole sleeve, providing stable support for the telescopic pole.

[0007] As a further improvement to the above solution, the rear end of the foldable fan head is connected to the top end of the telescopic rod, the bottom end of the telescopic rod sleeve has a multi-faceted stepped structure, the bottom end of the telescopic rod sleeve is connected to the top end of the base, and the rear end of the telescopic rod sleeve is fixedly connected with a barb.

[0008] Through the above technical solution, the telescopic rod sleeve provides stable support for the telescopic rod, ensuring that it remains stable during use and does not wobble or loosen. Combined with the telescopic rod, users can adjust the fan height as needed to meet the requirements of different usage scenarios and user heights, improving the product's practicality. The multi-faceted stepped structure allows for damping at specific angles of the telescopic rod, increasing the product's functional versatility. Users can adjust the angle of the telescopic rod to meet the needs of different usage scenarios. When the fan is folded, the barbs secure the folded fan head to prevent it from loosening.

[0009] As a further improvement to the above solution, a bearing is driven to the bottom of the base, a connecting plate is fixedly connected to the surface of the bearing, and a roller is driven to the bottom of the connecting plate. Four rollers are provided, and the bottom ends of the four rollers are in contact with the bottom of the base.

[0010] Through the above technical solution, the bearing serves to provide rotational support for the base. The rotation of the bearing allows users to easily adjust the fan direction to meet different usage needs. The bearing reduces friction and wear during base rotation, improving product lifespan and stability, while also reducing noise and enhancing user comfort. The casters facilitate fan rotation, allowing users to easily turn the fan and further improving ease of use.

[0011] As a further improvement to the above solution, a handle buckle is fixedly connected to the bottom of the base, and a screw is threaded inside the handle buckle. A silicone strip is installed at the rear end of the base, and a groove is opened on the surface of the silicone strip. The surface of the handle buckle is slidably connected to the inner wall of the groove on the surface of the silicone strip, and the left end of the silicone strip is fixedly connected to the rear end of the base.

[0012] Through the above technical solution, the handle buckle serves to secure the handle. By cooperating with the silicone strap, users can easily carry the electric fan, improving the product's portability. The handle buckle adopts a semi-concealed design, and the silicone strap can be extended and pulled up, and when tightened, it is hidden on the surface of the base, avoiding the messy look caused by exposed silicone strap and improving the product's aesthetics. The use of screws makes the installation and removal of the silicone strap very convenient. Users can easily install, remove, and replace the silicone strap as needed, improving the product's maintainability.

[0013] Compared with the prior art, the beneficial effects of this utility model are as follows: This utility model uses pins to fix the telescopic rod in the telescopic folding mechanism, which is simpler and faster than similar products that use a plastic sheet inside the aluminum alloy telescopic rod and then screws to fix it from the outer telescopic rod sleeve, thus improving the user experience. The base utilizes a combination of engineering plastic rollers and bearings to achieve rotational support, resulting in a simple structure that avoids the problem of ball bearings easily falling off, common in similar products. Furthermore, the use of bearings in the center eliminates the need for excessive lubrication and numerous screws required in similar products, reducing maintenance costs and failure rates. This utility model adopts a semi-concealed soft handle that can be extended and pulled out and then hidden when tightened, avoiding the messy feeling of similar products and improving the portability and aesthetics of the product. The base features a multi-faceted stepped structure, which allows for damping of the telescopic rod at specific angles, increasing the product's versatility. Users can adjust the angle of the telescopic rod as needed to meet the requirements of different usage scenarios. Attached Figure Description
