Description

Modular structure improvement of multi-function electric fan

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an electric fan, particularly a multi-kinetic energy, using a safe electric fan. BACKGROUND OF THE INVENTION The function of a conventional electric fan is to yaw only by using a combination of a yaw shaft and a clutch gear. Another improved model is a blower motor with a small gear motor for yaw drive. Another small gear motor is used for the pendulum transmission. Due to the small size of the teeth, it can only be swayed five times per minute with the yaw three times. It can only blow out the horizontal 8 character. If there is a weight error before and after the pitching of the pendulum, As a result, the life of the tooth is shortened, and the swing after the wind speed is increased can only maintain the above-mentioned certain speed, and cannot follow the adjustment of the wind speed to follow the swing of the speed.

Although the original multi-function electric fan can only be used with a blower motor, it can be used for directional blowing, yaw and adjustable width blowing, vertical vertical or oblique air blowing, M-shaped and other different wind-like waves. However, the multi-function electric fan generates the following defects and deficiencies during use.

1. When the original multi-function electric fan is tilted up and down or waved, in order to solve the front and rear movement space of the first (pitch adjustment seat:), the U-shaped gap of the front and rear of the base of the outer cover 5f is set, because there is no When the skateboard causes the gap to be easily moved back and forth, there is a safety hazard when the child invades the finger or the metal object and gets an electric shock.

Second, if the original multi-function electric fan is added with a skateboard, the first part of the slide is to be excavated under the normal method. The diameter hole of the middle section of the skateboard can be inserted into the first longitudinal neck, and the cutting is used in the middle pole. Disadvantages such as easy cracking. '

3. The guide groove of the original multi-function electric fan, after being traversed by the yaw arm support shaft, the upturn of the rear part of the original guide plate is a torsion spring connected in series between the head and the ear plate of the guide plate. The head spring is running through the yaw arm support shaft, but the space must be changed to be used for the motor to the switch between the switch and the wire passage. Therefore, the torsion spring must be abolished to avoid the wire between the segments being exposed to the cover. outer.

4. The wind-like change of the original multi-function electric fan yaw or wave blowing is caused by the positioning and steering of the guide plate and the yaw arm support shaft. When the extreme yaw is blown, the rear section of the guide plate will be traversed. The overall width of the front and rear outer edges of the cover and the seat can be prevented from touching the guide plate. Therefore, the appearance of the small and medium-sized electric fan is basically not confirmed. Requirement, because of the configuration of the telescopic guide, the outer shroud is shrunk, and the small electric fan below 12 inches cannot be opened to the market.

5. During the return stroke of the yaw of the original multi-function electric fan, the yaw arm support shaft is moved forward to the front groove of the guide plate to accelerate the steering, resulting in an increase in the yaw return stroke and a pause, because the yaw easing seat is not provided. improve.

6. The original multi-function electric fan has the function of up-and-down pitching, which balances the insufficient balance between the fan net group centered on the front arm and the rear part of the fan head, and the weighted iron installed behind the gear box not only occupies the outer shroud In the back-end space, in addition to increasing the cost of the iron, the weight of the different types of the fan network must be stored in a large amount of different weights and iron.
