Description

Technical Field

[0001] This utility model relates to the field of fan blade technology, and specifically to a novel fan blade. Background Technology

[0002] The fan blade is a crucial component of a fan, driven by a motor to rotate and generate airflow. Common fan blades typically have a curved cross-section. However, existing fan blades are generally single-layered, resulting in continuous airflow, significant resistance, slow airflow speed, insufficient airflow distance and power, and a less comfortable user experience, leading to unsatisfactory performance. Therefore, to avoid the shortcomings of existing technology, it is necessary to improve it. Utility Model Content

[0004] This utility model is achieved through the following technical solution:

[0005] A novel fan blade includes a hub, with a plurality of fan blades evenly distributed on the outer side of the hub. Each fan blade includes an upper spiral fan blade and a lower spiral fan blade. The beginning ends of both the upper and lower spiral fan blades are connected to the hub, and the ends of the upper spiral fan blades are connected to each other. The fan blades are inclined from bottom to top, and a guide plate is connected between the upper and lower spiral fan blades.

[0006] Furthermore, a hub cap is provided on the top of the hub.

[0007] Furthermore, the hub cover is provided with a connecting piece that connects to the upper spiral fan blade.

[0008] Furthermore, the upper spiral fan blade is provided with a connecting groove for positioning and installing the connecting piece, the outer side of the connecting piece is provided with a positioning block, and the inner side of the connecting groove is provided with a positioning groove corresponding to the positioning block.

[0009] Furthermore, the bottom of the hub cover is provided with a positioning mounting post, the top of the hub is provided with a positioning mounting hole corresponding to the positioning mounting post, the bottom of the hub cover is provided with a positioning connecting strip, and the top of the hub is provided with a positioning connecting groove corresponding to the positioning connecting strip.

[0010] Furthermore, the top of the hub cap is provided with a mounting groove.

[0011] Furthermore, the tail of the fan blade is arc-shaped.

[0012] Furthermore, the fan blade is provided with an opening.

[0013] Furthermore, a bushing is provided on the inner side of the hub.

[0014] Furthermore, four fan blades are evenly distributed on the outer side of the hub.

[0015] Compared to existing technologies, this utility model features a fan blade consisting of an upper spiral fan blade and a lower spiral fan blade, connected by an air guide plate. During operation, the upper and lower spiral fan blades rotate, and the airflow travels from the lower to the upper spiral fan blades, amplifying the airflow speed and resulting in a longer and stronger blowing distance. The upper and lower spiral fan blades, combined with the air guide plate, break up the airflow, making the user experience more comfortable and improving the overall performance.

Detailed Implementation

[0022] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0023] like Figures 1 to 4 The present invention discloses a novel fan blade, comprising a hub 1, with a plurality of fan blades 2 evenly distributed on the outer side of the hub 1. Each fan blade 2 includes an upper spiral fan blade 3 and a lower spiral fan blade 4. The beginning ends of both the upper and lower spiral fan blades 3 and 4 are connected to the hub 1, and the ends of the upper and lower spiral fan blades 3 are connected to each other. The fan blades 2 are inclined from bottom to top. A guide plate 5 connects the upper and lower spiral fan blades 3 and 4. During operation, the upper and lower spiral fan blades 3 and 4 rotate, and the airflow travels from the lower spiral fan blade 4 to the upper spiral fan blade 3, amplifying the airflow speed, resulting in a longer and stronger blowing distance. The upper and lower spiral fan blades 3 and 4, combined with the guide plate 5, break up the airflow, providing a more comfortable feel and better performance.

[0024] The top of the hub 1 is provided with a hub cover 6 to facilitate the installation of the fan blades.

[0025] The hub cover 6 is provided with a connecting piece 7 that connects to the upper spiral fan blade 3, making the fan blade 2 more securely installed and preventing the fan blade 2 from rotating relative to the hub cover 6.

[0026] The upper spiral fan blade 3 is provided with a connecting groove 8 for positioning and installing the connecting piece 7. The outer side of the connecting piece 7 is provided with a positioning block 9, and the inner side of the connecting groove 8 is provided with a positioning groove 10 corresponding to the positioning block 9, so that the connection between the connecting piece 7 and the upper spiral fan blade 3 is more stable and the rotation of the upper spiral fan blade 3 is more stable.

[0027] The bottom of the hubcap 6 is provided with a positioning mounting post 11, the top of the hub 1 is provided with a positioning mounting hole 12 corresponding to the positioning mounting post 11, the bottom of the hubcap 6 is provided with a positioning connecting strip 13, and the top of the hub 1 is provided with a positioning connecting groove 14 corresponding to the positioning connecting strip 13, so that the hubcap 6 is easy to position and install, and is installed firmly.

[0028] The wheel hub 1 and the wheel hub cover 6 can be molded as one piece.

[0029] The top of the hub cover 6 is provided with a mounting groove 15, which facilitates the connection and installation of the motor shaft of the motor with the hub cover 6.

[0030] The tail of fan blade 2 is arc-shaped to reduce the noise of fan blade 2 during operation.

[0031] The fan blade 2 has an opening 16, which increases the degree to which the airflow is broken up by the fan blade 2, but also increases the operating noise.

[0032] The absence of perforation 16 in the fan blades 2 reduces noise.

[0033] The inner side of the hub 1 is provided with a bushing 17, and the hub 1 is connected to the motor shaft of the motor.

[0034] Four fan blades 2 are evenly distributed on the outer side of the hub 1. The four fan blades with an upper and lower structure evenly and stably break up the airflow, making the body feel more comfortable.
