Description

Technical Field

[0001] The invention relates to the technical field of fans, and in particular to a wireless induction powered air circulation fan. Background Art

[0002] A fan is an electrical appliance that is widely used in daily life. It uses a motor to drive the fan blades to rotate, thereby accelerating the air flow and cooling it down. It is mainly used for cooling and circulating air.

[0003] In order to supply air to a larger area and improve the cooling effect, current fans basically use a swinging structure at the fan head, which enables the fan to swing its head, thereby achieving a larger angle of air supply. In order to be able to supply air at a larger angle, some manufacturers often modify the swinging mechanism in the hope of obtaining a larger swinging angle. However, since the motor needs to be connected to the power supply through a power cord when driving the fan blades to rotate, the fan is limited to swinging only and cannot achieve 360° rotation. The reason is that during the 360° rotation of the fan, the power cord connected to the fan will inevitably be entangled, so that if the number of rotations is large, the power cord will be damaged or even broken. Therefore, the fans currently on the market cannot truly achieve 360° rotation, but can only achieve reciprocating left and right swings. Among the swinging fans on the market, the maximum swing angle can only reach 350°, and cannot truly achieve 360° rotation and air supply.

DETAILED DESCRIPTION

[0022] In order to facilitate the understanding of those skilled in the art, the present invention is further described below in conjunction with the embodiments and drawings, and the contents mentioned in the embodiments are not intended to limit the present invention. The present invention is described in detail below in conjunction with the drawings.

[0023] An embodiment of the present invention provides a wireless induction powered air circulation fan. In this technical solution, a seat body 200 for installing a fan assembly 100 is set as a fixed seat 210 and a rotating seat 200 that are rotatably connected to each other, and the fan assembly 100 is installed on the rotating seat 200. The power supply device 400 for providing driving power to the fan assembly 100 is a wireless power supply device 400, which specifically includes an electromagnetic transmitting assembly 410 and an electromagnetic receiving assembly 420 that are respectively fixedly installed on the fixed seat 210 and the rotating seat 200. According to the principle of electromagnetic induction, the electromagnetic receiving assembly 420 generates current, thereby providing power for rotation of the fan assembly 100. In this technical solution, the power cord used to transmit current to the fan assembly 100 is removed in the process of driving the fan assembly 100 to rotate, so that the driving device can drive the rotating seat 200 to rotate freely along the fixed seat 210, thereby realizing a true 360° rotation, and there is no limit on the number of turns, which can meet the user's blowing needs.

[0024] Specifically, Figure 1-5As shown, a wireless induction powered air circulation fan provided by an embodiment of the present invention includes a fan assembly 100, and also includes: a seat body 200, a driving device and a power supply device 400, wherein the seat body 200 includes a fixed seat 210 and a rotating seat 200 rotatably connected to the fixed seat 210, and the fan assembly 100 is assembled on the rotating seat 200; the driving device is arranged inside the seat body 200, and is used to drive the rotating seat 200 to rotate along the end surface of the fixed seat 210; the power supply device 400 is used to be electrically connected to the fan assembly 100 and provide a starting power supply to the fan assembly 100, and includes an electromagnetic transmitting assembly 410 and The electromagnetic receiving component 420, wherein the electromagnetic transmitting component 410 is arranged in the fixed seat 210, includes an excitation coil 411 and an excitation control board 412 which are electrically connected to each other, and the excitation control board 412 is connected to the power supply to transmit current to the excitation coil 411 and generate a magnetic field; the electromagnetic receiving component 420 and the electromagnetic transmitting component 410 are arranged in the rotating body correspondingly, and the electromagnetic receiving component 420 includes an induction coil 421 which cuts the magnetic field lines and an induction control board 422 which is electrically connected to the induction coil 421, and the induction control board 422 is electrically connected to the fan assembly 100 to provide a driving power supply.

[0025] During the operation of the air circulation fan provided in this embodiment, the driving device can be connected to an external power supply, and can also be electrically connected to the power supply device 400, so that the rotating seat 200 can make a 360° rotational movement along the fixed seat 210 under the drive of the driving device. At the same time, the excitation control board 412 is electrically connected to the external power supply, and the power supply is supplied to the excitation coil 411 after rectification and voltage stabilization. It is worth mentioning that the excitation control board 412 is provided with a protection circuit, a voltage stabilization circuit, a rectification circuit and other control circuits, so that the excitation coil 411 can be protected. After the current is passed through the magnetic coil, An excitation magnetic field is generated, and the magnetic lines of force of the magnetic field are cut by the induction coil 421 located in the rotating seat 200. Due to the principle of electromagnetic induction, an electromotive force is generated in the induction coil 421, and because the induction coil 421 is a closed loop, an induced current is formed in the induction coil 421. After being processed by the induction control board 422, the fan assembly 100 is provided with a driving power supply, so that the fan assembly 100 can rotate and supply air normally. It is worth mentioning here that protection control circuits such as a protection circuit and a voltage stabilizing circuit are arranged on the induction control board 422, which can enable the fan assembly 100 to rotate stably. During this process, the driving device drives the rotating seat 200 and the fan assembly 100 to achieve a 360° rotational motion. In the process of driving and powering the fan assembly 100, an induction power supply method based on the electromagnetic principle is adopted, which avoids the use of a power cord for power supply, thereby ensuring that during the cyclic rotation of the rotating seat 200, there is no interference with the power cord, thereby achieving a true 360° rotational motion, and can achieve unlimited and dead-angle rotation to meet the user's blowing needs.

[0026] In this embodiment, in order to meet more usage scenarios, the air circulation fan can be used normally without an external power supply. A first rechargeable battery pack 413 is also provided on the electromagnetic emission component 410. The first rechargeable battery pack 413 is electrically connected to the excitation control board 412, and a plug interface connected to the first rechargeable battery pack 413 and used for charging is provided on the fixing seat 210. In other words, the first rechargeable battery pack 413 can be charged in advance and then power the excitation coil 411 without an external power supply, so that the induction coil 421 can generate an induced current through electromagnetic induction, thereby providing a driving power supply for the fan assembly 100 to rotate.

[0027] In order to further ensure the reliability of the fan operation, the electromagnetic receiving component 420 also includes a second rechargeable battery pack 423 electrically connected to the induction control board 422, and the second rechargeable battery pack 423 is electrically connected to the fan component 100. During use, the induced current generated by the electromagnetic induction of the induction coil 421 is distributed through the induction control board 422, so as to charge the second rechargeable battery pack 423. In the case where the induction coil 421 cannot generate the induced electromotive force, the second rechargeable battery pack 423 can also provide power to the fan component 100 to drive it to rotate.

[0028] In this embodiment, the driving device is used to drive the rotating seat 200 to rotate along the fixed seat 210, so as to drive the fan assembly 100 to perform a 360° rotational motion, so as to achieve uninterrupted and dead angle-free 360° air supply.

There are many ways to drive the drive motor 310, which can more conveniently power the drive motor 310, thereby saving the electric energy generated by the induction coil 421.
