Abstract

The utility model discloses a swing guide blade for a Hongyun fan, comprising a rotor wheel, an eccentric shaft, a rocker with a sliding groove and swing guide blades. The rotor wheel, the eccentric shaft, and the bushing of an eccentric shaft which are arranged in one sliding groove are arranged on a slow motor; the sliding groove is fixed into one body with one rocker; a plurality of transmission shafts which are sheathed together with the transmission holes of a plurality of swing guide blades are arranged on the other side of the rocker; rotary shafts on the swing guide blades are sheathed together with circular holes on a framework. Compared with the wind guiding device of the present Hongyun fan, the utility model makes use of wind energy more effectively.

Description

Swing guide blades for Hongyun fan

The utility model relates to a kind of box fan swing guide blade.

The box fan of people's use now is made up of fan electromotor, slow speed motor etc.Fan electromotor drives the purpose that the fan blade rotation reaches blowing, and slow speed motor drives and rotates the purpose that the wind guiding blade disc spins reaches increases the fan angle of radiation.But present rotation wind guiding blade dish is failed fully effectively radiation wind energy.Because when above or below the air guide channel that rotates the wind guiding blade dish is transferred to, above or below its electric fan wind had been directed to, at this moment, wind energy did not obtain fully effectively radiation and gives the user.

The purpose of this utility model provides a kind of wind energy that makes and obtains the swing guide blade that the user is given in fully effectively radiation.

The purpose of this utility model is finished with following mode: a moving runner is installed on the slow speed motor axle, an eccentric shaft is installed on moving runner, load onto a chute on eccentric shaft.Chute and a fork are fastened on one, and the another side of fork has transmission shaft, and the driving hole of transmission shaft and swing guide blade is nested together.On the swing guide blade upper-lower position rotatingshaft is arranged, the circle hole sleeve on it and the box fan framework together.After slow speed motor starts, drive the eccentric shaft rotation on the moving runner, eccentric shaft slides up and down in the chute on fork on the one hand, promotes the chute fork on the other hand and swings, and make left-right rotation by the promotion of the transmission shaft on chute fork swing guide blade.After fan motor started, electric fan wind was by radiation wind energy back and forth from left to right behind the swing guide blade.

Because of blade is to swing, can not make above or below wind is radiated.Therefore, it has effectively utilized wind energy more fully than existing rotation wind guiding blade dish.

Introduce structure of the present utility model and installation below in conjunction with accompanying drawing.

Fig. 1 is the utility model plan view.

Fig. 2 is the sectional view of Fig. 1 along the B-B line.

Fig. 3 is the sectional view of Fig. 1 along the A-A line.

Fig. 4 is Fig. 2 C part enlarged view.

Fig. 5 is Fig. 3 D part enlarged view.

With reference to accompanying drawing, on slow speed motor ［ 7 ］, load onto a moving runner ［ 10 ］, on moving runner ［ 10 ］, load onto an eccentric shaft ［ 11 ］.In addition, a chute ［ 8 ］ is enclosed within on the eccentric shaft ［ 11 ］, chute ［ 8 ］ is fastened on one with a fork ［ 9 ］.Fork ［ 9 ］ is gone up another side several transmission shafts ［ 12 ］, respectively with the neutral position of several swing guide blades ［ 5 ］ on driving hole ［ 13 ］ be nested together.Circular hole ［ 2 ］ on rotatingshaft ［ 3 ］ on swing guide blade ［ 5 ］ upper-lower position and the box fan framework ［ 1 ］ is nested together.Driving hole ［ 13 ］ is designed to more than half circular hole, during assembling as long as stick into transmission shaft ［ 12 ］ in the driving hole ［ 13 ］ just passable.Fan electromotor ［ 6 ］ drives fan blade ［ 4 ］ radiation wind energy.
