Such as, when detection means detects that human height is higher or human body apart from fan 200 it is more remote when, the people that detection means amount is detected
Body height or distance signal pass to controller, and controller controls driving machine according to the human height or range information received
Structure drives the first column 1 (upward as shown in Fig. 1-Fig. 5) mobile from inside to outside in the second column 2, the first column 1 of increase and the
The whole height of two columns 2, so as to raise the height of fan first 201；When controller is detected, human height is relatively low or human body distance
When fan 200 is nearer, the human height's signal or distance signal that detect are passed to controller by detection means, controller according to
The human height received or range information, control drive mechanism drive the first column 1 in the second column 2 inwardly (such as Fig. 1-
It is downward shown in Fig. 5) mobile, the whole height of the first column 1 of reduction and the second column 2, so as to reduce the height of fan first 201
Degree.
By the detection means for being provided for detecting human height and/or distance so that fan 200 is highly adjusted more certainly
Dynamicization and intellectuality, go for children, old man, personage with disabilities (such as blind person or trick of trick inconvenience
Handicapped person scholar) etc..
Alternatively, controller also has braking function, and when the first column 1 moves to extreme position, controller can
Braking mode drive mechanism, so as to ensure the reliability and security in the height adjustment of fan 200.
For example, in the specific example of the present invention, as shown in Fig. 3-Fig. 5, the top of the second screw rod 41 is provided with the
One limit switch 46, the bottom of the second column 2 is provided with the second limit switch 47, alternatively, the first limit switch 46 and second
Limit switch 47 can be touch-switch, and the first limit switch 46 and the second limit switch 47 are electrically connected with the controller.When
When first column 1 moves up to extreme position, the first limit switch 46 will be touched with the roof of the second column 2, the first limit
Bit switch 46 is triggered, and sends a signal to controller, and controller controls drive mechanism stopping to act according to the signal received；
When the first column 1 moves downwardly to extreme position, the second limit switch 47 will be touched with the second screw rod 41, and second is spacing
Switch 47 is triggered, and sends a signal to controller, and controller controls drive mechanism stopping to act according to the signal received.
Certainly, the application it is not spacing this, the first limit switch 46 can also located at the second column 2 roof on, second
Limit switch 47 can also be located at the bottom of the second screw rod 41.
Further, shown in reference picture 4, the bottom of drive link 45 is provided with end cap 48, when the first column 1 is moved down extremely
When at extreme position, end cap 48 will be touched with the second limit switch 47 for being located at the bottom of the second column 2, it is to avoid the second screw rod 41 is direct
Touch, if the second screw rod 41 is directly touched in rotary state with the second limit switch 47, not only wear and tear with the second limit switch 47
Seriously, in some instances it may even be possible to the second limit switch 47 can be caused to damage, by setting end cap 48 to avoid the second screw rod 41 and second
Limit switch 47 is directly touched, and improves the reliability of the lifting process of fan 200.The plate-like structure that end cap 48 can be formed, by
This can preferably trigger the second limit switch 47 when the first column 1 moves downwardly to extreme position.
With continued reference to the axle sleeve shown in Fig. 4, being additionally provided between the screw rod 41 of second bearing 44 and second with the cooperation of drive link 45
49, axle sleeve 49 and the outer ring of second bearing 44 are fixedly linked, and the first limit switch 46 is on the upper surface of axle sleeve 49, thus not
Only so that the first limit switch 46 it is easier for installation, and the first limit switch 46 can be avoided to follow 41 turns of the second screw rod
It is dynamic, if the first limit switch 46 is directly touched in rotary state with the roof of the second column 2, not only serious wear, in some instances it may even be possible to
The first limit switch 46 can be caused to damage, by setting axle sleeve 49 to improve the reliability of the lifting process of fan 200.
As shown in Figure 4, the bottom of fan first 201 is provided with the installation cavity 2011 for being used for installing the second motor 43, installation cavity
2011 bottom wall has perforation, and the motor shaft in installation cavity 2011 with the second motor 43 is stretched on the top of drive link 45 by perforation
Transmission is connected.
