Description

Three-dimensional wind direction electric fan structure

The creation is a three-dimensional wind direction electric fan structure, which enables the electric fan to rotate in the up, down, left and right directions to form a multi-directional three-dimensional space blowing effect.

Investigate, the fan of the known fan swings in the direction of the air, all of which are swinging back and forth. In other words, the motor is supported by the base and swings to the right and left. Therefore, the blowing direction can only be described as "horizontal" and cannot be " The vertical direction of the upper and lower sides cannot be changed upwards, downwards, left and right. Therefore, the conventional fan makes the air convection effect in the upper and lower spaces poor. In the "air-conditioned room", the convection effect on the upper hot air and the lower-lower air below is poor.

In addition, it is conventional to have a fan that can be turned up, down, left, and right. The small motor is mounted on the support, and the power of the small motor allows the large motor of the fan to move up and down. Although it can be moved up, down, left and right, the structure is more complicated, the cost is higher, and the failure rate is higher and less durable due to the complicated structure.

This creation is to improve the above shortcomings. The main technology and purpose are: the fan motor is assembled in the front shell and the rear shell, and the rear end of the motor is provided with a shift gear assembly, which is combined with a crank arm to the rear shell, and the front end of the motor is provided with Rotating the positioning frame and the support base in the upper, lower, left and right directions, the rotating shaft of the motor is formed in the positioning frame and the support base, and when the motor shaft rotates, the gear teeth can be linked The gear shaft of the wheel assembly is formed with the crank arm as the pivot point, and the motor as a whole rotates to change the angles of up, down, left and right, so that the fan blades can blow various wind directions of up, down, left and right. With the structure of the present invention, the structure can be simplified to reduce the cost and reduce the failure rate, and the air in the upper, lower, left and right spaces in the space can be quickly convected.

Please refer to the first, second, third, fourth and fifth figures, the motor 10 is assembled in the front and rear shells 1 and 2 of a fan, the blade 3 is assembled at the front end of the rotating shaft 11 of the motor 10, and the net cover 4 is wrapped around the blade 3; The rear end of the motor 10 is provided with a shifting gear assembly 12, and the motor shaft 11 is coupled to the gear rotating shaft 13 of the shifting gear assembly 12. The gear rotating shaft 13 is connected with a curved arm 14 which is combined with the rear housing 2 by an axial center 15. The front end of the front housing 1 is provided with a positioning frame 20, and the left and right sides of the positioning frame 20 have a shaft center 21 and a shaft seat 22 combined with the front housing 1, and the positioning frame 20 is provided. A support base 23 is provided, and the upper and lower shafts 24 of the support base 23 are combined with the positioning frame 20, and the support base 23 has a through hole 25 for the shaft 10 of the motor 10 to pass through, and the support base 23 is formed to support the front end of the motor 10.

According to the above structure, the effect of this creation is described in detail as follows: Please refer to the 3, 4, and 5, when the motor 10 shaft 11 is actuated, it can interlock the gear shaft 13 of the shift gear assembly 12, and the crank arm 14 is rotated at an angle, and the front end of the motor 10 shaft 11 is pivotally coupled to the support base 23, supporting The seat 23 has the upper and lower shafts 24 pivotally coupled to the positioning frame 20, and the positioning frame 20 is further assembled with the left and right shafts 21 in the front housing 1, so that the motor 10 can be guided by the crankshaft 14 and the positioning frame 20, The support base 23 is a rotation pivot point, and forms an upper, lower, left, and right rotation angle, that is, the fan blade 3 assembled by the rotation shaft 11 can be reciprocally changed up, down, left, and right to achieve a space in the space. The effect of fast convection under, left and right. Moreover, the present invention only uses the structure of the crank arm 14, the positioning frame 20, and the support base 23, that is, the motor 10 can be "suspended" in the rotation angles of the front and rear shells 1, 2, which can simplify the structure, reduce the cost, and improve the structure. Durable effect.

In summary, the structure of this creation does have excellent practicality and enhanced efficiency, and it is in line with the new patent principle, so please grant a patent.
