[0022] In the description of the present invention, it should be noted that the terms "length", "width", "up", "down", "front", "back", "left", "right", "top", "bottom", "inside", "outside", etc., indicating the orientation or positional relationship, are based on the positional relationship shown in the accompanying drawings, and are only for the convenience of describing the present invention, and do not indicate that the device referred to must have a specific orientation or operate in a specific orientation. Therefore, it should not be understood as a limitation on the present invention.

[0023] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as those commonly understood by those skilled in the art to which this application pertains. The terms used herein in the specification of this application are for the purpose of describing specific embodiments only and are not intended to limit this application.

[0024] The present invention will be described in detail below with reference to the accompanying drawings and embodiments.

[0025] A fan and a waterproof elbow thereof, such as Figure 1 As shown, it includes an air guide ring 1, a motor 2 and a curved pipe body 3. A wiring port is opened on the motor 2, and a plurality of motor leads 12 are arranged in the wiring port. The curved pipe body 3 is sleeved on the motor leads 12. The air guide ring 1 is designed to guide the airflow to ensure the uniformity and efficiency of the air flow. The air guide ring 1 is usually made of lightweight and high-strength materials, such as ABS plastic or stainless steel. These materials can reduce the overall weight of the fan while maintaining the stability of the structure. The design of the curved pipe body 3 takes into account the waterproof requirements of the fan to ensure the safety of the motor leads 12 in a humid environment. By sleeved the motor leads 12 inside the curved pipe body 3, the risk of the motor leads 12 being exposed to the outside can be reduced, and the possibility of electrical failure can be reduced.

[0026] Specifically, the elbow body 3 is made of PA6+GF20 material, and the elbow body 3 includes a front end 4 and a rear end 5. An arc-shaped opening 1 6 is provided on the front end 4, and an arc-shaped opening 2 7 is provided on the rear end 5. The curvature of the arc-shaped opening 1 6 is smaller than the curvature of the arc-shaped opening 2 7. The arc-shaped opening 1 6 and the arc-shaped opening 2 7 are both located below the front end 4 and the rear end 5. When the operator installs the elbow body 3, the motor lead 12 can be placed into the elbow body 3 through the arc-shaped opening 1 6 and the arc-shaped opening 2 7. The design of the arc-shaped opening 1 6 and the arc-shaped opening 2 7 allows the motor lead 12 to pass smoothly, reducing obstacles during the installation process and improving installation efficiency. After the motor lead 12 is successfully embedded in the rear end 5, force is applied to the motor lead 12 on the side of the front end 4 so that it is embedded in the front end 4. End 5 can limit the motor lead 12, thereby improving the installation efficiency. By setting the arc-shaped opening 1 6 and the arc-shaped opening 2 7, the flow of water is facilitated, and both are located below the elbow body 3, reducing the possibility of water accumulation, avoiding problems such as corrosion and bacterial growth inside it, and ensuring the normal operation of the fan. Since the curvature of the arc-shaped opening 1 6 is smaller than the curvature of the arc-shaped opening 2 7, this design helps to optimize air flow, reduce air flow resistance, and thus improve the efficiency of the fan. By reducing water accumulation and optimizing air flow, this design helps to improve the overall performance of the fan, including improving efficiency and extending the service life of the fan. PA6+GF20 is a high-strength, heat-resistant, and chemical-resistant material, which enables the elbow body 3 to maintain stable performance in various environments, thereby extending the service life of the elbow body 3.

[0027] Furthermore, an angle is formed between the front end 4 and the rear end 5, and the angle is 90° to 180°. By setting the bending angle of the elbow body 3, the airflow direction can be effectively guided, and the turbulence and energy loss of the airflow at the bend can be reduced, thereby improving the efficiency of the fan. At the same time, the bending angle helps to reduce the noise generated when the fan is running, especially when the airflow speed inside the elbow is high, and the appropriate bending angle can provide better structural stability, especially when subjected to external pressure or vibration.

[0028] A screw sleeve 9 is provided on the motor 2, and the front end 4 is interference fit with the screw sleeve 9. Specifically, the size of the screw sleeve 9 is M20*1.5. Through the above arrangement, the operator can move along the motor lead 12 to the side of the nut after putting the elbow body 3 on the motor lead 12, apply force to the elbow body 3 and make it interference fit with the screw sleeve 9. The interference fit improves the connection strength between the elbow body 3 and the screw sleeve 9, ensures the precise positioning of the front end 4 on the screw sleeve 9, and avoids the elbow body 3 from loosening during use, which is very important for ensuring the overall performance and stability of the fan, and the tight connection can improve the waterproof performance of the elbow body 3 and reduce the risk of moisture entering the inside of the motor 2. At the same time, the size of the screw sleeve 9 is M20*1.5, which is a standard thread specification, which facilitates standardized design and production and reduces costs.

[0029] The rear end 5 is detachably connected to a cable tie 8, and a embedding groove 10 is provided on the rear end 5 to accommodate the embedding of the cable tie 8, and the depth of the embedding groove 10 is greater than the thickness of the cable tie 8. By setting the cable tie 8, the operator can bundle the cable tie 8 after fixing the bent pipe body 3, so that the motor lead 12 is fixed to the bent pipe body 3, avoiding the motor lead 12 from shaking, and improving the stability of the fan during use. The detachable connection design of the cable tie 8 makes the installation and disassembly process more convenient, does not require additional tools, and is easy to maintain and replace. By setting the embedding groove 10, when the cable tie 8 is embedded in the embedding groove 10, it can provide additional fixing force to ensure that the cable tie 8 will not loosen under vibration or wind, thereby improving the stability of the overall structure. The design of the embedding groove 10 can prevent the cable tie 8 from being directly exposed to the outside, which can protect the cable tie 8 and extend the service life of the cable tie 8.

[0030] Furthermore, a limiting groove 11 for accommodating the motor lead 12 is provided on the rear end 5, and the cross-section of the limiting groove 11 is arc-shaped. Through the above-mentioned arrangement, the bent tube body 3 can be suitable for motor leads 12 of different lengths. The motor lead 12 only needs to be embedded in the limiting groove 11. The arc-shaped limiting groove 11 can provide additional protection for the motor lead 12 to prevent the motor lead 12 from being mechanically damaged during installation or fan operation, and the arc-shaped cross-section can reduce the friction between the motor lead 12 and the limiting groove 11, which helps to extend the service life of the motor lead 12. At the same time, the arc-shaped limiting groove 11 can simplify the installation process of the motor lead 12, making it easier to guide and fix the motor lead 12 in the correct position.

[0031] The above description is merely a preferred embodiment of the present invention. The scope of protection of the present invention is not limited to the above embodiment. All technical solutions based on the concept of the present invention are within the scope of protection of the present invention. It should be noted that for those skilled in the art, certain improvements and modifications that do not depart from the principles of the present invention should also be considered within the scope of protection of the present invention.
