Detailed Description

To make the purpose, technical solution and advantages of the embodiments of the present invention clearer, the technical solution in the embodiments will be clearly and completely described below with reference to the drawings in the embodiments of the present invention, and the following embodiments are used to illustrate the present invention.

As shown in fig. 1, 2 and 3, the present embodiment provides an automatic steering and speed-adjusting fan, which includes: base 2, along the bracing piece 1 of vertical setting on base 2. The top end of the support rod 1 is connected with an operation box 4 through a steering mechanism. A driving motor is arranged in the operation box 4 and is connected with the protective cover 10; the driving motor is connected with the fan blades 5 in the protective cover 10 in a transmission way, and the air flow generated by the fan blades 5 when the fan blades 5 rotate is blown out from the front surface of the protective cover 10. The front face of the shield 10 is provided with a heat source tracking device.

As shown in fig. 4, 5, and 6, the heat source tracking device includes a mounting board 601 on the front surface of the protection cover 10, and an infrared sensor 602 provided on the front surface of the mounting board 601. The infrared sensor 602 is a commercially available sensor that detects a field of view of 2 ° for detecting a target temperature directly in front of the hood 10. The controller 604 on the side of the operation box 4 is electrically connected to the infrared sensor 602, and is configured to control the steering mechanism at intervals to drive the operation box 4 and the protection hood 10 to rotate left and right, detect the temperature of the target right in front of the protection hood 10 through the infrared sensor 602, and control the steering mechanism to steer the protection hood 10 and the fan blades 5 inside the protection hood 10 to the direction of the highest temperature target after one rotation. This allows the fan to continue blowing air to the highest temperature target, typically the human body. During use, the controller 604 swings around every 3 to 5 minutes to find the highest temperature target.

In the implementation process, the steering mechanism can adopt a closed-loop stepping motor as a steering motor. The closed loop stepper motor may report the real-time angle to the controller 604. The controller 604 can be built by using the existing PLC or single-product machine to realize the functions, or can be built by using commercially available devices such as a time delay relay and the like, and the improvement of the method and software is not involved.

In some embodiments, the mounting plate 601 is further provided with an ultrasonic ranging probe 603 which has the same detection direction as the infrared sensor 602. The ultrasonic ranging probe 603 is electrically connected to the controller 604, and the controller 604 detects an object distance right in front of the protection cover 10 through the ultrasonic ranging probe 603, and controls the rotation speed of the driving motor according to the object distance to adjust the air speed blown out by the fan blade 5. The principle of adjusting the wind speed is to adopt higher wind speed for a distant target and lower wind speed for a closer target so as to ensure that the wind power felt by users is stable and consistent. The function of adjusting the wind speed also does not need to improve software and a method, and can be realized by adopting a controller and a frequency modulator which are sold in the market and matching with a driving motor. The driving motor is electrically connected to the controller 604.

In some embodiments, the steering mechanism includes a square box 301 mounted on the top end of the support rod 1, a steering motor 302 is mounted on the square box 301, a rotating shaft 303 is fixed to an output end of the steering motor 302, and the other end of the rotating shaft 303 penetrates through the square box 301 and is fixed to the operation box 4.

The protection mechanism is arranged on the mounting plate (601), the protection mechanism comprises a protection frame 701 fixed on the mounting plate 601, the infrared sensor (602) is located inside the protection frame 701, and one side, far away from the mounting plate 601, of the protection frame 701 is connected with a protection cover plate 702 used for shielding and protecting a detection window of the outer sensor 602 through a sliding assembly in a sliding mode.

The sliding assembly comprises a sliding groove 901 formed in one side of the protective frame 701, a sliding block 902 is connected to the sliding groove 901 in a sliding mode, and the sliding block 902 is fixed to the protective cover plate 702.

A handle 8 is fixed to the shield cover 702. Through the pushing effect of the handle 8 on the protective cover plate 702 and the sliding guide effect of the sliding groove 901 and the sliding block 902 on the protective cover plate 702 after being stressed, the protective cover plate 702 is pushed to cover the protective frame 701, the infrared sensor 602 is shielded and protected, and external dust is prevented from falling into a detection window of the infrared sensor 602, so that the protective effect is achieved.

The fan is in the use, and the user starts the switch of fan, drives pivot and flabellum 5 through the inside driving motor of control box 4 and rotates, and the rotation through flabellum 5 carries out cooling heat dissipation and handles, at the radiating in-process of cooling. The controller 604 drives the operation box 4 and the protective cover 10 above the operation box to rotate left and right through the steering mechanism every 4 minutes, detects the temperature of the target right in front of the protective cover 10 through the infrared sensor 602, and controls the steering mechanism to steer the protective cover 10 and the fan blades 5 inside the protective cover 10 to the direction of the highest temperature target after one rotation. Therefore, the fan can continuously blow the highest temperature of the human body, and the practicability of the fan is improved;

in the process of using the fan, the ultrasonic ranging probe 603 is used for sensing the distance between a user and the fan, which is the highest temperature target in the highest temperature target room, and transmitting actual distance information to the controller 604, when the distance between the user and the fan is small, the situation that the user is cooled by heat dissipation due to strong wind force is avoided, the rotating speed of the driving motor is controlled through the controller 604, the wind force of the fan blades 5 is reduced, and when the distance between the user and the fan is large, the situation that the cooling and heat dissipation effects are poor due to the fact that the distance is far away is avoided.

The foregoing has described in detail preferred embodiments of the present invention. It should be understood that numerous modifications and variations can be devised by those skilled in the art in light of the principles of this invention without the use of inventive faculty. Therefore, the technical solutions that can be obtained by a person skilled in the art through logic analysis, reasoning or limited experiments based on the prior art according to the concepts of the present invention should be within the scope of protection defined by the claims.
