[0001] The present application belongs to the technical field of fan blades, and specifically relates to a non-ferrous metal fan blade. Background Art

[0002] With the arrival of summer, the weather is getting hotter and hotter, and fans are used more and more frequently. The air output effect of the fan usually depends on the motor power, blade structure and mesh structure. Non-ferrous metal fan blades refer to fan blades made of a non-ferrous metal (such as copper, aluminum, brass, etc.). This material usually has good thermal conductivity and corrosion resistance, and also has a certain decorative effect. Blades made of non-ferrous metals may add a unique look to the fan, making it look more refined and upscale. In addition, non-ferrous metals can also play a good heat dissipation effect in specific designs, making the heat dissipation performance of the fan better.

The rear blade seat 2 is fitted to the rear end of the front blade seat 1, and the angle between the three front threaded holes 8 opened inside the front blade seat 1 is 120°, and the angle between the six rear threaded holes 11 opened inside the rear blade seat 2 is 60°. The front blade seat 1 and the rear blade seat 2 are threadedly connected by bolts 10, and the interior of the front blade seat 1 and the rear blade seat 2 rotates through the rotating shaft 13 to drive the blades to rotate. In use, when it is necessary to adjust the maximum air supply and minimum air supply of the blades, the bolt 10 can be rotated, and the bolt 10 can be disassembled from the interior of the rear blade seat 2, so that the rear blade seat 2 can be rotated at the rear end of the front blade seat 1. At this time, after the rear blade seat 2 is rotated 60°, the positions of the rear blades 6 and the front blades 3 can be staggered, so that the blade combination between the front blades 3 and the rear blades 6 is changed from three to six, and then the bolt 10 is rotated to the interior of the rear blade seat 2 again, and the front blade seat 1 and the rear blade seat 2 are fixed. The maximum and minimum air supply volumes can be adjusted. When the positions of the front blades 3 and the rear blades 6 coincide, the maximum air supply volume is less than the maximum air supply volume when the angles of the front blades 3 and the rear blades 6 are staggered. The rear blade ring 5 and the outer blades 7 installed at the top of the rear blades 6 can provide an internal and external double-layer air supply mode, which makes the air supply effect better.

After the surface of the rotating shaft 13 is sleeved with the front fan blade seat 1 and the rear fan blade seat 2, the threaded rod 14 connected to the top end of the rotating shaft 13 can be threadedly connected with the threaded cover 9 at the front end of the front fan blade seat 1, and the front fan blade seat 1 and the rear fan blade seat 2 are pressed and attached to the rear end of the rotating shaft 13 by the threaded cover 9. The rear end size of the rotating shaft 13 is slightly larger than the front end of the rotating shaft 13, and the position between the front fan blade seat 1, the rear fan blade seat 2 and the rotating shaft 13 can be fixed.

[0033] Reference Figure 3 The rear end of the rotating shaft 13 is fixedly connected with a motor seat 15, and three positioning holes 16 are opened on the surface of the motor seat 15. Starting the motor seat 15 can drive the rotating shaft 13 to rotate. The positioning holes 16 are used for positioning. The bolts 10 are not installed inside the positioning holes 16, but only when the front fan blade seat 1 and the rear fan blade seat 2 are installed, it is convenient for multiple threaded holes to be positioned.

The fan slot 19 provided inside the fan base 18 is used to provide a space for the fan blades to rotate, and the fan rear cover 17 installed at the rear end of the fan base 18 is used to fix the position of the motor base 15.

[0035] Reference Figure 4 The rear end of the motor base 15 is provided with a motor cover 20, and the top end of the motor cover 20 is threadedly connected with a fastening bolt 21. The fastening bolt 21 can fix the motor cover 20 to the rear end of the motor base 15, and opening the motor cover 20 can facilitate maintenance and installation of the motor base 15.

[0036] The implementation principle of a non-ferrous metal fan blade embodiment of the present application is as follows: a rotating shaft 13 is connected to a motor shaft, and when the fan is started, the rotating shaft 13 can be driven to rotate, and the surface of the rotating shaft 13 can be used to sleeve the front blade seat 1 and the rear blade seat 2. After the surface of the rotating shaft 13 is sleeved with the front blade seat 1 and the rear blade seat 2, the threaded rod 14 connected to the top of the rotating shaft 13 can be threadedly connected with the threaded cover 9 at the front end of the front blade seat 1, and the front blade seat 1 and the rear blade seat 2 are squeezed and attached to the rear end of the rotating shaft 13 by the threaded cover 9. The rear end size of the rotating shaft 13 is slightly larger than the front end of the rotating shaft 13, and the position between the front blade seat 1, the rear blade seat 2 and the rotating shaft 13 can be fixed. The interior of the front blade seat 1 and the rear blade seat 2 rotates through the rotating shaft 13, driving the blades to rotate. In use, when it is necessary to adjust the maximum and minimum air supply of the fan blades, the bolt 10 can be rotated, and the bolt 10 can be removed from the inside of the rear blade seat 2, so that the rear blade seat 2 can be rotated at the rear end of the front blade seat 1. At this time, after the rear blade seat 2 is rotated 60°, the positions of the rear blades 6 and the front blades 3 can be staggered, so that the blade combination between the front blades 3 and the rear blades 6 is changed from three to six. At this time, the bolt 10 is rotated to the inside of the rear blade seat 2 again, and the front blade seat 1 and the rear blade seat 2 are fixed. The maximum and minimum air supply can be adjusted. When the positions of the front blades 3 and the rear blades 6 coincide, the maximum air supply is less than the maximum air supply when the angles of the front blades 3 and the rear blades 6 are staggered. The rear blade ring 5 and the outer blade 7 installed at the top of the rear blade 6 can provide an internal and external double-layer air supply mode, so that the air supply effect is better. The fan blades of the device have inner and outer layers and front and rear layers, and the angle between the front and rear layer blades can be rotated to adjust the maximum and minimum air supply volume of the fan, thereby improving the applicability of the device.
