Problems solved by technology

Generally, the suction cup uses a spring steel sheet to connect the front plate and the suction cup plate. When the suction cup is sucked and released, the spring steel sheet will generate a lot of noise; while the general suction cup hub adopts a flat key design, and a special flat key is required when assembling with the spindle drive rod. , high cost, complex assembly

Embodiment Construction

[0010] The present invention will be further described now in conjunction with accompanying drawing.

[0011] Such as figure 1 and figure 2 As shown, the present invention includes a suction cup hub 1, the suction cup hub 1 includes an outer ring 2, and an inner ring 3, there is a certain distance between the outer ring 2 and the inner ring 3, and the outer ring 2 and the inner ring 3 are sleeved on the suction cup hub. The nitrile rubber 4 between the inner rings 3, and the spline groove 5 provided at the center of the suction cup hub 1 for connecting the main shaft drive rod of the electric fan.

[0012] Compared with the existing technology, the use of NBR instead of the spring steel sheet can prevent foreign objects from being stuck into the suction cup during the operation of the fan, and protect the fan. At the same time, the rubber suction cup has the characteristics of low noise when sucking and releasing; and adopts The spline groove design reduces the assembly com...

Abstract

The invention relates to an electric fan and particularly relates to a sucker for the electric fan. The sucker comprises a sucker hub, wherein the sucker hub comprises an outer ring and an inner ring; a certain distance is arranged between the outer ring and the inner ring; the sucker is characterized by further comprising a nitrile rubber and a spline slot; the nitrile rubber is arranged between the outer ring and the inner ring of the sucker hub in a sleeving way; the spline slot is formed in the center of the sucker hub and is used for connecting a spindle driving rod for the electric fan. Compared with the prior art, the sucker for the electric fan has the characteristics that the nitrile rubber is used for replacing a spring steel sheet, so that the foreign matter clamped in the sucker during a running process of the fan is eliminated, a function of protecting the fan is achieved, and meanwhile, when the rubber sucker sucks, the noise is low. The design for the spline slot is adopted, so that the assembling complexity is reduced, the flat key is no longer assembled, the spline slot is directly assembled with the spindle driving rod and the cost is lowered.

Description

technical field [0001] The invention relates to an electric fan, in particular to a suction cup of the electric fan. Background technique [0002] The suction cup is one of the most important parts in the assembly process of the electric fan. Its function is: after the rotor ring is energized, the coil ring generates magnetic force, and the suction cup and the pulley are attracted. When the fan rotates, the pulley is driven by the belt, the pulley makes the suction cup run, and the suction cup drives the main shaft drive rod to run to make the internal parts of the fan run. [0003] The internal moving parts of the fan will produce dynamic unbalance during operation, and the suction cup can offset the amount of dynamic unbalance generated by the internal parts of the fan. Generally, the suction cup uses a spring steel sheet to connect the front plate and the suction cup plate. When the suction cup is sucked and released, the spring steel sheet will generate a lot of noise...
