Description

A high-efficiency centrifugal wind wheel with noise reduction holes

Technical Field

The invention relates to the technical field of centrifugal wind wheels, and in particular to a high-efficiency centrifugal wind wheel with noise reduction holes.

Background Art

A centrifugal fan is a common mechanical device, mainly used for the transportation and processing of air or gas. It sucks air or gas from the air inlet through the high-speed rotating impeller, then guides it inside the casing and finally discharges it from the air outlet. The basic working principle of a centrifugal fan is to use centrifugal force, that is, the centrifugal force generated by the high-speed rotation of the impeller pushes the air or gas to the outlet.

When a centrifugal fan is in use, the air volume generated will change according to the angle between the blades and the hub. When the motor power is constant, the air volume will gradually increase with the increase of the angle. When it reaches a certain angle, it is the optimal angle and the air volume is maximum. Continuing to increase the angle will not increase the air volume. Most of the existing blades are fixed, and the air volume can only be maximum when the power is at the set power. It cannot be adjusted according to user needs and has poor adaptability.

The rotating ring 19 rotates under the rotation of the power transmission ring 21, so that the torsion spring 2 45 is changed from a relaxed state to a tensioned state. During the rotation of the rotating ring 19, the pawl 2 47 contacts the ratchet 2 58 one by one to limit the rotating ring 19. When it needs to be reset, the power ring 33 is manually pushed, and the power ring 33 drives the connecting component 35 to move horizontally. The driving block 51 on the connecting component 35 enters the driving groove 50, so that the pawl 2 47 rotates, and the pawl 2 47 moves away from the ratchet 2 58.

The power ring 33 drives the power transmission ring 21 to move horizontally through the connecting component 35. The power transmission ring 21 drives the rotating ring one 19 to rotate through the transmission mechanism 25. When the wind pressure starts to decrease from the maximum, the transmission mechanism 25 separates from the rotating ring one 19 to determine the optimal rotation angle. The block 28 on the rotating shaft 7 enters the slide groove two 30 after rotation and contacts with the rotating ring one 19. The movement of the rotating shaft 7 drives the transmission gear one 8 cooperates with gear 1 3 to reverse the rotation shaft 7, and then the block 28 passes through the through groove 32 on the rotating ring 19, and the rotating shaft 7 moves to make the fixed half gear 17 cooperate with the gear 1 3 to fix the blade 2. When it needs to be reset, the push ring 24 is pressed, and the push ring 24 pushes the fixed shaft 13 to move horizontally, so that the rotating shaft 7 passes through the through groove 32 and enters the slide groove 1 20, and then the power ring 33 is pushed, and the power ring 33 drives the connecting assembly 35 to move, and the driving block 51 on the connecting assembly 35 resets the rotating ring 19, and the push rod 1 52 on the slide rod 38 and the push rod 2 56 on the fixed sleeve 16 reset the slide rod 38, and then the micro motor is started, and the rotating mechanism 15 drives the transmission gear 1 8 to rotate.
