Turbofan with adjustable air outlet angle

Abstract

The turbofan comprises a bottom frame, the top of the bottom frame is fixedly connected with a bearing frame by forming an opening, a first annular sliding groove plate is fixedly connected to the position, located on the inner side of the bearing frame, of the bottom of an inner cavity of the bottom frame, and a first annular sliding block is slidably connected to the interior of the first annular sliding groove plate; the invention relates to the technical field of turbofans. According to the turbo fan with the adjustable air outlet angle, the operation table is installed at the top of the gear disc, meanwhile, the motor can drive the clamping frame to rotate through meshing of the meshing gear and the gear ring, and through cooperative use of the two structures, the turbo fan can rotate according to actual requirements; the direction and angle of air outlet of the worm-wheel fan are adjusted, the practicability of the worm-wheel fan is greatly improved, and meanwhile the worm-wheel fan is more stable in operation after being adjusted by being matched with the limiting teeth and the self-locking function of the motor.

Description

technical field [0001] The invention relates to the technical field of turbo blowers, in particular to a turbo blower with an adjustable wind outlet angle. Background technique [0002] Turbo fan, also known as centrifugal fan, centrifugal fan is driven by the motor to rotate the impeller, the blades in the impeller force the gas to rotate, and work on the gas to form wind pressure. The current turbo fan has a single structure and is installed by bolts and other components. Fixed installation, when special applications are required, the air outlet angle of the fan cannot be adjusted according to the actual situation, which reduces the practicability of the fan itself. At the same time, the air inlet of the current fan is exposed, and foreign objects outside are easily inhaled during operation, thus reducing the practicability of the fan itself. cause damage to the fan. SUMMARY OF THE INVENTION [0003] In view of the deficiencies of the prior art, the present invention pr...

AI Technical Summary

Problems solved by technology

[0003] Aiming at the deficiencies of the prior art, the present invention provides a turbo fan with an adjustable air outlet angle, which solves the problem that the existing fan is fixedly installed and cannot adjust the air outlet angle according to the actual situation, and the problem that foreign matter is easily sucked into the fan during operation
