[0016] This specific embodiment is a fan impeller with a reinforced structure, and its structural schematic diagram is shown below. Figures 1-7 As shown, it includes: an impeller seat 10, a fan blade 13 mounted on the outer surface of the impeller seat 10 by a screw, and the fan blade 13 is stamped and formed with a groove 22 and a protrusion 19. A reinforcing ring 7 is provided on the outside of the impeller seat 10. The end of the fan blade 13 away from the impeller seat 10 is welded to the inner ring of the reinforcing ring 7.

A fixing mechanism is provided on the outside of the impeller seat 10.

[0017] Specifically, the combination of impeller seat 10, fan blade 13, and reinforcing ring 7 fixes both ends of the fan blade 13, increasing its strength. The protruding strip 19 on the back of the fan blade 13, when rotating, accelerates the airflow nearby, creating a low-pressure zone. Air from a distance flows towards the blade due to the pressure difference, thus enhancing wind output. The support mechanism increases the strength of the fan blade 13, effectively preventing deformation and ensuring its performance and lifespan. The heat dissipation mechanism prevents heat transfer from the motor to the fan impeller, preventing overheating and damage during prolonged use and ensuring its lifespan. The fixing mechanism facilitates quick installation and use of the fan impeller.

[0018] Furthermore, two bent pieces 8 are provided on both sides of the reinforcing ring 7, and the ends of the two bent pieces 8 that are close to each other are welded to the outer ring of the reinforcing ring 7.

[0019] Specifically, by setting the bending piece 8, the two sides of the reinforcing ring 7 are made more rounded to prevent scratches, and the bending piece 8 can increase the strength of the reinforcing ring 7.

[0020] Furthermore, the support mechanism includes an N-type reinforcing frame 5, which is welded and installed inside the groove 22. A fixing seat 20 is installed at the bottom of the N-type reinforcing frame 5, and the fixing seat 20 is fixedly installed with a limit ring by screws. A baffle 14 is welded and installed on the inner wall of the groove 22.

[0021] Specifically, by setting up the N-type reinforcing bracket 5 and the baffle 14, the N-type reinforcing bracket 5 and the fan blade 13 are integrated, which strengthens the fan blade 13 as a whole and increases its strength. By setting up the fixing seat 20, the bottom end of the N-type reinforcing bracket 5 is fixed with screws, which increases the fixing area between the fan blade 13 and the impeller seat 10, further strengthening the fan blade 13, increasing its stability and strength, effectively preventing the fan blade 13 from deforming, and ensuring the performance and service life of the fan blade 13.

[0022] Furthermore, the heat dissipation mechanism includes a heat dissipation ring 16, an insulation ring 11 is installed on the inner ring of the limiting ring, and a heat dissipation ring 16 is installed on the inner ring of the insulation ring 11. A heat dissipation groove 21 is formed on the outer surface of the heat dissipation ring 16.

[0023] Specifically, the heat dissipation ring 16 and heat dissipation groove 21 can dissipate the heat conducted by the motor. In conjunction with the heat insulation ring 11, it can effectively prevent heat from being conducted to the limit ring and fan blades 13, prevent the fan blades 13 from overheating and causing damage during long-term use, and ensure the service life of the fan impeller.

[0024] Furthermore, a noise-absorbing mesh 9 is installed on the outer surface of the heat dissipation ring 16, and the noise-absorbing mesh 9 is located outside the heat dissipation groove 21.

[0025] Specifically, the noise reduction mesh 9 eliminates the noise generated by airflow through the heat dissipation slot 21.

[0026] Furthermore, the fixing mechanism includes a central shaft 1, the outer side of the impeller seat 10 is provided with the central shaft 1, the outer surface of the impeller seat 10 is provided with a positioning ring 4, the outer surface of the central shaft 1 is provided with a mounting hole 17, the outer surface of the central shaft 1 is provided with a threaded hole 2, the outer side of the central shaft 1 is provided with a lead screw 3, and the inner side of the impeller seat 10 is provided with a nut 15.

[0027] Specifically, by inserting the central shaft 1 into the interior of the impeller seat 10, with the positioning ring 4 abutting against the outer surface of the heat dissipation ring 16, and then using the nut 15 to tighten it onto the central shaft 1, the central shaft 1, heat dissipation ring 16, impeller seat 10, and fan blade 13 are installed. Next, the motor shaft is inserted into the mounting hole 17, and the lead screw 3 is screwed into the threaded hole 2 and abutted against the keyway of the motor shaft to fix it, thus installing the fan impeller.

[0028] Furthermore, a pin 6 is fixedly connected to the outer surface of the positioning ring 4, and a socket 18 is provided on the outer surface of the heat dissipation ring 16.

[0029] Specifically, the pin 6 is inserted into the socket 18 to increase the stability of the connection between the positioning ring 4 and the heat dissipation ring 16.

[0030] Furthermore, a connecting seat 12 is provided on the outside of the heat dissipation ring 16.

[0031] Specifically, the connector 12 can be screwed into the nut 15 for installation and fixation. The connector 12 covers the middle of the fan impeller, increasing the aesthetics of the fan impeller.

[0032] This utility model discloses a fan impeller with a reinforced structure. The fan blade 13 is fixed at both ends by a combination of an impeller seat 10, a fan blade 13, and a reinforcing ring 7, increasing the strength of the fan blade 13. The fan blade 13 has a stamped back protrusion 19. When the fan blade 13 rotates, the protrusion 19 on the back of the fan blade 13 accelerates the airflow nearby, creating a low-pressure area. Air from a distance flows towards the fan blade due to the pressure difference, thereby enhancing the wind power output. The support mechanism increases the strength of the fan blade 13, effectively preventing deformation and ensuring its performance and service life. The heat dissipation mechanism prevents heat from the motor from being conducted to the fan impeller, preventing overheating and damage during prolonged use and ensuring the impeller's service life. The fixing mechanism facilitates quick installation and use of the fan impeller. By setting the N-type reinforcing bracket 5 and the baffle 14, the N-type reinforcing bracket 5 and the fan blade 13 are integrated, which strengthens the fan blade 13 as a whole and increases its strength. By setting the fixing seat 20, the bottom end of the N-type reinforcing bracket 5 is fixed with screws, which increases the fixing area between the fan blade 13 and the impeller seat 10, further strengthening the fan blade 13, increasing its stability and strength, effectively preventing the fan blade 13 from deforming, and ensuring the performance and service life of the fan blade 13. By setting up the heat dissipation ring 16 and the heat dissipation groove 21, the heat conducted by the motor can be dissipated. With the setting up of the heat insulation ring 11, the heat can be effectively prevented from being conducted to the impeller seat 10 and the fan blades 13, preventing the fan blades 13 from overheating and being damaged during long-term use, and ensuring the service life of the fan impeller. By inserting the central shaft 1 into the interior of the impeller seat 10, the positioning ring 4 abuts against the outer surface of the heat dissipation ring 16, and then using the nut 15 to tighten it onto the central shaft 1, the installation of the central shaft 1, the heat dissipation ring 16, the impeller seat 10 and the fan blade 13 is achieved. Then, the motor shaft is inserted into the mounting hole 17, and the screw 3 is screwed into the screw hole 2 and abuts against the keyway of the motor shaft to fix it, so that the fan impeller is installed.
