Application of electric slip ring in 360° full-range air supply fan
The reason why the traditional electric fan can automatically shake its head left and right are because there is a gearbox at the back of the fan head. When the motor rotates, it drives the gear, and the gear drives the connecting rod. One end of the connecting rod is fixed so that the fan head reciprocates left and right. Though this structure has realized the function that the electric fan shakes the head automatically from side to side, it limits the automatic side-to-side shaking of the electric fan and can only be within a small angle range.
Is there a kind of unrestricted rotating electric fan that can be omnidirectional? In the spirit of exploration, the author really found the relevant technical implementation plan.
The prior art has also realized the function of the electric fan to automatically shake the head up and down, but the same electric fan can only shake the head up and down automatically within a small angle range. Powertrain failure.
For this reason, it has become a reality to manufacture 360° full-range air supply electric fans through slip ring technology, so as to solve the problem that the electric fans in the prior art can only shake their heads up, down, left, and right within a small angle range. Wire entanglement causes damage to the wire, which makes the power system failure.
In order to achieve the above object, the technical scheme is as follows:
A 360° full-range air supply electric fan includes a base, a fan head bracket, and a fan head, the fan head bracket is arranged above the base, the fan head bracket includes a first bracket and a second bracket, and there is a gap between the first bracket and the second bracket. There is room to turn the fan head over;
The first bracket is provided with a first accommodation cavity, the first DC motor is installed in the vertical direction in the first accommodation cavity, the first steering column is arranged in the horizontal direction in the first accommodation cavity, and the first steering column is close to the second bracket One end protrudes from the first bracket, and the first DC motor is mechanically connected to the first steering column through the first transmission mechanism connect.
A second accommodating cavity is provided in the second bracket, and a second steering column is arranged in the horizontal direction in the second accommodating cavity. The end of the second steering column close to the first bracket protrudes from the second bracket. The first conductive slip ring; the fan head is installed between the first bracket and the second bracket through the first steering column and the second steering column, and the center point of the fan head, the first steering column, and the second steering column is located on the same horizontal plane ;
The base is equipped with a second DC motor, a second transmission mechanism, a second conductive slip ring, and a coupling, the second DC motor is mechanically connected to the coupling through the second transmission mechanism, and one end of the coupling is connected to the second conductive slip ring. The other end of the coupling is connected to the fan head bracket; the external power supply enters from the base, passes through the second conductive slip ring, and then is transmitted to the first conductive slip ring.
Preferably, both the first transmission mechanism and the second transmission mechanism are worm gear transmission mechanisms. The inner surface of the first accommodating cavity is provided with reinforcing ribs, and the reinforcing ribs are used to fix the first DC motor in a vertical direction. Wind holes are arranged on the first support and the second support. The fan head bracket is U-shaped. The fan head support is a hollow structure as a whole.
The base is also provided with a speed-regulating mechanism. The speed-regulating mechanism includes a third motor, a potentiometer, and a speed-regulating module. The output end of the third motor is mechanically connected to the potentiometer, and the potentiometer is electrically connected to the input end of the speed-regulating module. The output terminal of the module is electrically connected to the second DC motor and the first DC motor.
The base includes a bottom plate and a bottom cover, the bottom cover is fastened on the bottom plate, the first DC motor is fixed on the bottom cover, and the third motor is fixed on the bottom plate. A temperature and humidity detection module is also provided on the surface of the base, and the temperature and humidity detection module is used for monitoring the temperature and humidity of the environment.
The first steering column and the second steering column are fixed on the first bracket and the second bracket through the first bearing and the second bearing.
Compared with the existing traditional products, the products created by the above technologies have the following beneficial effects:
Provides a 360° full-range air supply fan, including a base, a fan head bracket, and a fan head, the fan head bracket is arranged above the base, and the fan head bracket leaves a space for the fan head to turn over, and the fan head is installed in this space, the first DC motor, the first transmission mechanism, and the first conductive slip ring are installed in the fan head bracket; the second DC motor, the second transmission mechanism, the second conductive slip ring, and the coupling are installed in the base, and the second DC The motor is mechanically connected to the coupling through the second transmission mechanism, one end of the coupling is connected to the second conductive slip ring, and the other end of the coupling is connected to the fan head bracket; the external power supply enters from the base and flows through the second conductive slip ring. The ring is then transmitted to the first conductive slip ring.
Finally, by adding a conductive slip ring to the rotating shaft, the electric fan head can freely rotate 360° up and down, left and right along the rotating shaft without causing damage to the wires due to entanglement of the wires, resulting in failure of the power system.
Is it interesting for everyone? The key technology is the use of electric slip rings.
