The aluminum foil has good conductivity and reflectivity, which can effectively reflect external electromagnetic interference and reduce the electromagnetic impact on the motor.

The cable of the controller 11 passes through the wire hole 14 and the wiring tube 15 to be connected with the motor 2. The connector 12 is fixedly connected to one end of the lower side of the mounting shell 7. The aluminum foil sheet 13 is provided with an opening at the position corresponding to the wiring tube 15. Several groups of heat sinks 17 pass through the interior of the mounting shell 7. The air inlet 18 is communicated with the wind cavity 19 and the air outlet 21, and the air outlet 21 is spirally arranged upward.

[0032] The controller 11 inside the lower cavity 9 is cooled by several groups of heat sinks 17 on the front and rear sides. When the four groups of rotating fan heads 2211 are working, the outside air enters the upper cavity 8 through the two groups of heat dissipation ports 16, and is respectively introduced into the interior of the wind cavity 19 by several groups of air inlets 18. The incoming airflow accelerates the heat dissipation of the several groups of heat sinks 17, and then enters the wind cavity 19. Through the arrangement of several groups of guide blades 20, the time the incoming airflow stays inside is increased, and the heat generated by the motor 2 is more effectively taken away, so that it is discharged outwardly from several groups of air outlets 21 on the upper side, thereby accelerating the overall effect. The aluminum foil 13 has good conductivity and reflectivity, and can effectively reflect external electromagnetic interference, thereby reducing the electromagnetic influence on the motor 2.

[0033] The control assembly 22 includes a disk 221 fixedly mounted on the bottom of the inner side of the upper cavity 8, a fixed sleeve 222 fixedly mounted on the upper end of the disk 221 near the center, a bearing 223 fixedly mounted on the inner side of the fixed sleeve 222, a shaft 224 fixedly mounted on the inner ring of the bearing 223, a gear 225 fixedly mounted on the outer side of the shaft 224, a block 226 fixedly mounted on the upper end of the shaft 224, and a fixed sleeve 222 fixedly mounted on the inner side of the upper cavity 8 near the center of the disk 221.

[0034] Gear 1 225 is meshed with the surrounding transmission gears 2212 respectively, the block 226 is adapted to the notched joint on the lower side of the rotating shaft 3, the two sets of gear 2 2210 are meshed, the rotating airflow of the fan head 2211 blows upwards, and the transmission gear 2212 is meshed with the corresponding set of gear 2 2210.

[0035] The mounting shell 7 is fixed to the bottom of the housing 1, and the controller 11 is installed inside the lower cavity 9. At the same time, the cutout joint at the bottom of the rotating shaft 3 is connected to the block 226. When the motor 2 is working, the block 226 and the shaft 1 224 are driven to rotate clockwise, and the gear 1 225 drives the four sets of meshing transmission gears 2212 to rotate counterclockwise. The counterclockwise rotating transmission gear 2212 drives the meshing set of gears 2210 to rotate clockwise, and the other set of gears 2210 rotates counterclockwise at the same time, driving the connected fan head 2211 to rotate. , the four sets of gear two 2210 blow the air flow upward at the same time, and when the motor 2 rotates counterclockwise, the gear one 225 will push the four sets of transmission gears 2212 to rotate clockwise, and the gear one 225 will first push the four sets of transmission gears 2212 to move to the other side of the sleeve 2213, and engage with the gear two 2210 connected to the fan head 2211, driving the fan head 2211 to rotate counterclockwise, so that when the motor 2 rotates forward and reverse, the fan head 2211 can always keep blowing the air flow upward, thereby preventing the hot air generated by the motor 2 from moving downward and causing thermal impact on the controller 11‌.

[0036] Slide sleeves 2213 are fixedly provided on the upper end of the disc 221 in the directions of the two groups of gears 2210 on all sides, limit strips 2214 are fixedly provided on the inner sides of the four groups of slide sleeves 2213, movable shafts 2215 are slidably provided on the inner sides of the four groups of slide sleeves 2213, and shaft rods 3 2216 are fixedly provided on the inner sides of the four groups of movable shafts 2215, telescopic shafts 2217 are movably provided on both sides of the slide sleeve 2213, and limit plates 2218 are fixedly provided on the opposite ends of the two groups of telescopic shafts 2217, and springs 2219 are sleeved between the outer sides of the two groups of telescopic shafts 2217 and the slide sleeve 2213 near the limit plates 2218.

The shaft rod 3 2216 is fixedly connected to the transmission gear 2212 , and the spring 2219 is fixedly connected to the limit plate 2218 and the sliding sleeve 2213 .

[0038] When the transmission gear 2212 rotates clockwise, it will generate a squeezing force on the right telescopic shaft 2217, and the limit plate 2218 will move outward to stretch the spring 2219. Therefore, when the transmission gear 2212 rotates counterclockwise, the spring 2219 will generate a thrust on the telescopic shaft 2217 and the movable shaft 2215, promoting the transmission gear 2212 to separate from the clockwise meshing gear 2210 and mesh with another set of transmission gears 2212.

[0039] Working principle: During installation, the mounting shell 7 is fixed to the bottom of the housing 1, the controller 11 is installed inside the lower cavity 9, and the cutout joint at the bottom of the rotating shaft 3 is docked with the block 226. When the motor 2 is working, the block 226 and the shaft 1 224 are driven to rotate clockwise, and the gear 1 225 drives the four sets of meshing transmission gears 2212 to rotate counterclockwise. The counterclockwise rotating transmission gear 2212 will drive the meshing set of gears 2210 to rotate clockwise, while the other set of gears 2210 rotates counterclockwise at the same time, driving the connected fan head 221 1 rotates, and the four sets of gears 2210 blow air upwards at the same time. When the motor 2 rotates counterclockwise, the gear 1 225 pushes the four sets of transmission gears 2212 to rotate clockwise, and the gear 1 225 first pushes the four sets of transmission gears 2212 to move to the other side of the sliding sleeve 2213, and meshes with the gear 2 2210 connected to the fan head 2211, driving the fan head 2211 to rotate counterclockwise, so that when the motor 2 rotates forward and reverse, the fan head 2211 can always keep blowing air upwards, so as to prevent the hot air generated by the motor 2 from moving downwards and causing thermal influence on the controller 11; When the external transmission gear 2212 rotates clockwise, it will generate a squeezing force on the right telescopic shaft 2217, and the limit plate 2218 will move outward to stretch the spring 2219. Therefore, when the transmission gear 2212 rotates counterclockwise, the spring 2219 will generate a thrust on the telescopic shaft 2217 and the movable shaft 2215, promoting the transmission gear 2212 to separate the clockwise meshing gear 2210 and mesh with another set of transmission gears 2212; finally, the heat dissipation of the controller 11 inside the lower cavity 9 is carried out through the front and rear side groups of heat sinks 17, and the four rotating fan heads 2211 work During operation, outside air enters the upper cavity 8 through two groups of heat dissipation ports 16, and is respectively introduced into the interior of the wind cavity 19 by several groups of air inlets 18. The incoming airflow accelerates the heat dissipation of several groups of heat sinks 17, and then enters the wind cavity 19. Through the arrangement of several groups of guide plates 20, the time of the incoming airflow inside is increased, and the heat generated by the motor 2 is more effectively taken away, and then discharged outwardly from several groups of air outlets 21 on the upper side, accelerating the overall effect. The aluminum foil 13 has good conductivity and reflectivity, and can effectively reflect external electromagnetic interference and reduce the electromagnetic influence on the motor 2.

[0041] Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
