Description

Technical Field

[0001] This utility model relates to the field of fan technology, specifically to a wireless inductively powered air circulator fan. Background Technology

[0002] Fans are a common household appliance. They use a motor to drive the fan blades to rotate, thereby accelerating airflow and cooling the air. They are mainly used for cooling and air circulation.

[0003] To improve cooling efficiency and deliver airflow over a larger area, most current fans employ a oscillating mechanism at the fan head. This allows the fan to swing, achieving a wider airflow angle. To further enhance this effect, some manufacturers modify the oscillation mechanism, hoping to achieve an even greater swing angle. However, because the motor drives the fan blades and connects to the power supply via a power cord, the fan is limited to oscillation, not 360° rotation. This is because the power cord would inevitably become tangled during a 360° rotation, potentially damaging or even breaking the cord with repeated rotations. Therefore, current fans cannot truly achieve 360° rotation; they can only oscillate back and forth. The maximum oscillation angle among oscillating fans on the market is only 350°, not true 360° rotation.

[0004] Therefore, there is an urgent need for a new technology to solve the above-mentioned technical problems and provide a circulating fan that can rotate 360°. Utility Model Content

Detailed Implementation

[0036] To facilitate understanding by those skilled in the art, the present invention will be further described below with reference to embodiments and accompanying drawings. The content mentioned in the embodiments is not intended to limit the present invention. The present invention will be described in detail below with reference to the accompanying drawings.

[0037] This utility model embodiment provides a wireless induction-powered air circulator fan. In this technical solution, the base 200 for mounting the fan assembly 100 is configured as a fixed base 210 and a rotating base 200 rotatably connected to each other. The fan assembly 100 is mounted on the rotating base 200. The power supply device 400 for providing driving power to the fan assembly 100 is a wireless power supply device 400, specifically including an electromagnetic transmitting component 410 and an electromagnetic receiving component 420 respectively fixedly mounted on the fixed base 210 and the rotating base 200. According to the principle of electromagnetic induction, the electromagnetic receiving component 420 generates current, thereby providing power for the rotation of the fan assembly 100. In this technical solution, the power line used to transmit current to the fan assembly 100 is removed during the process of driving the fan assembly 100 to rotate. Thus, the driving device can drive the rotating base 200 to rotate freely along the fixed base 210, thereby achieving true 360° rotation without any limit on the number of rotations, which can meet the user's air blowing needs.

[0038] Specifically, such as Figure 1-5 As shown in the figure, a wireless inductively powered air circulator fan provided by this utility model embodiment includes a fan assembly 100, and further includes a base 200, a drive device, and a power supply device 400. The base 200 includes a fixed base 210 and a rotating base 200 rotatably connected to the fixed base 210. The fan assembly 100 is mounted on the rotating base 200. The drive device is disposed inside the base 200 and is used to drive the rotating base 200 to rotate along the end face of the fixed base 210. The power supply device 400 is electrically connected to the fan assembly 100 and provides starting power to the fan assembly 100, and includes an electromagnetic emission component 410. The electromagnetic receiving assembly 420 is provided, wherein the electromagnetic transmitting assembly 410 is disposed within the fixed base 210 and includes an excitation coil 411 and an excitation control board 412 electrically connected to each other. The excitation control board 412 is connected to a power source to transmit current to the excitation coil 411 and generate a magnetic field. The electromagnetic receiving assembly 420 is disposed within the rotating base corresponding to the electromagnetic transmitting assembly 410, and the electromagnetic receiving assembly 420 includes an induction coil 421 that cuts magnetic field lines and an induction control board 422 electrically connected to the induction coil 421. The induction control board 422 is electrically connected to the fan assembly 100 to provide drive power.

[0039] In this embodiment, during operation, the air circulator fan's drive unit can be connected to an external power source or electrically connected to the power supply unit 400. This allows the rotating base 200 to rotate 360° along the fixed base 210 under the drive of the drive unit. Simultaneously, the excitation control board 412 is electrically connected to the external power source and supplies the power to the excitation coil 411 after rectification and voltage regulation. It is worth noting that the excitation control board 412 is equipped with protection circuits, voltage regulation circuits, rectification circuits, and other control circuits to protect the excitation coil 411 after current is applied to it. An excitation magnetic field is generated, and the magnetic field lines are cut by the induction coil 421 located inside the rotating seat 200. Due to the principle of electromagnetic induction, an electromotive force is generated in the induction coil 421. Since 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 current is transmitted to the fan assembly 100, providing driving power to the fan assembly 100 so that the fan assembly 100 can rotate and deliver air normally. It is worth noting that the induction control board 422 is equipped with protection circuits, voltage stabilization circuits and other protection control circuits, which can make the fan assembly 100 rotate stably. During this process, the drive device drives the rotating base 200 and the fan assembly 100 to achieve 360° rotation. In the process of driving the fan assembly 100, an induction power supply method based on electromagnetic principles is adopted, which avoids the use of power lines for power supply. This ensures that there is no interference with the power lines during the cyclic rotation of the rotating base 200, and can achieve true 360° rotation. It can rotate continuously without restrictions or dead angles to meet the user's air blowing needs.

[0040] In this embodiment, to meet more usage scenarios and enable normal operation of the air circulator fan without an external power source, a first rechargeable battery pack 413 is installed on the electromagnetic emission assembly 410. The first rechargeable battery pack 413 is electrically connected to the excitation control board 412, and the mounting base 210 is provided with a connector for charging the first rechargeable battery pack 413. In other words, the first rechargeable battery pack 413, after being pre-charged, can supply power to the excitation coil 411 without an external power source. This allows the induction coil 421 to generate an induced current through electromagnetic induction, thereby providing driving power to the fan assembly 100 and causing it to rotate.

[0041] To further ensure the reliability of the fan's 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 assembly 100. During use, the induced current generated by the electromagnetic induction of the induction coil 421 is distributed through the induction control board 422 to charge the second rechargeable battery pack 423. Even when the induction coil 421 is not present and cannot generate an induced electromotive force, the second rechargeable battery pack 423 can still provide power to drive the fan assembly 100 to rotate.

[0042] In this embodiment, the driving device is used to drive the rotating seat 200 to rotate along the fixed seat 210, thereby enabling the fan assembly 100 to perform a 360° rotational motion, achieving uninterrupted and dead-angle-free 360° airflow. In the technical solution provided by this utility model patent, to ensure greater stability and torque during the rotation of the rotating seat 200 along the fixed seat 210, the following configuration is made: a convex ring 211 is formed on the fixed seat 210 or the rotating seat 200, and internal teeth 212 are provided on the inner wall of the convex ring 211; the driving device is disposed on the rotating seat 200 or the fixed seat 210 opposite to the convex ring 211; the driving device includes a fixedly mounted drive motor 310, and a drive gear 311 is fixedly mounted on the output shaft of the drive motor 310, meshing with the convex ring 211 to form an internal meshing gear set, such as... Figure 3-4 As shown, the drive motor 310 is located at an eccentric position on the rotating surface of the rotating seat 200. Through the meshing of the drive gear 311 and the convex ring 211, the rotating seat 200 is driven to rotate. By setting the drive gear 311 and the convex ring 211 as an internal meshing gear set structure, the rotating seat 200 can be more stable during rotation. At the same time, the gear transmission is more stable and can provide a larger rotational torque, which can have a larger load capacity, ensuring that the rotating seat 200 and the fan assembly 100 are more stable during the 360° rotation.

[0043] Specifically, in this embodiment, a convex ring 211 is disposed on the fixed seat 210, that is, a convex ring 211 is formed on the surface of the fixed seat 210 opposite to the rotating seat 200, and the inner wall of the convex ring 211 is provided with internal teeth 212; the driving device includes a drive motor 310 and a drive gear 311, wherein the drive motor 310 is fixedly installed inside the rotating seat 200 and is electrically connected to the electromagnetic receiving component 420; the drive gear 311 is fixedly installed on the output shaft of the drive motor 310 and meshes with the internal teeth 212 of the convex ring 211.

[0044] In this embodiment, the drive motor 310 is fixedly mounted on the rotating seat 200. The electromagnetic receiving component 420 provides drive power to the drive motor 310, thereby driving the rotating seat 200 to rotate through gear transmission. Specifically, after the induction coil 421 generates an induced current, the induction control board 422 distributes the current to the drive motor 310, thereby starting the drive motor 310 to rotate. With this technical solution, the drive device is set on the upper side of the convex ring 211, that is, the power source is set on the upper side of the convex ring 211. During the internal meshing of the drive gear 311 and the convex ring 211, the motor can rotate synchronously with the rotating seat 200, ensuring that the rotating seat 200 is more stable during rotation.

[0045] To further improve the rotational stability of the rotating seat 200, a rotating hole 213 coaxially arranged with the convex ring 211 is provided on the fixed seat 210; a rotating shaft 221 is formed on the rotating seat 200, which passes through the rotating hole 213 and is rotatably connected therein, and an anti-detachment component 222 is detachably connected to the end of the rotating shaft 221, the size of the anti-detachment component 222 being larger than the diameter of the rotating hole 213.

[0046] In other embodiments, a convex ring 211 is disposed on the rotating seat 200, that is, a convex ring 211 is formed on the surface of the rotating seat 200 opposite to the fixed seat 210, and the inner wall of the convex ring 211 is formed with internal teeth 212; the driving device includes a drive motor 310 and a drive gear 311, wherein the drive motor 310 is fixedly installed inside the fixed seat 210 and forms a parallel or series circuit with the electromagnetic emission component 410 and is electrically connected to the power supply; the drive gear 311 is fixedly installed on the output shaft of the drive motor 310 and meshes with the internal teeth 212 of the convex ring 211.

[0047] In this embodiment, since the drive motor 310 is mounted on the fixed base 210, the power supply for driving the drive motor 310 can be provided by the electromagnetic emission component 410, or directly by an external source, or by the first rechargeable battery pack 413. There are multiple ways to drive the drive motor 310, which makes it more convenient to power the drive motor 310 and saves the electrical energy generated by the induction coil 421.

[0048] In this embodiment, in order to ensure the rotational stability of the rotating seat 200, the rotating seat 200 is formed with a rotating hole 213 coaxially arranged with the convex ring 211; a rotating shaft 221 is formed on the fixed seat 210, which passes through the rotating hole 213 and is rotatably connected therein, and an anti-detachment member 222 is detachably connected to the end of the rotating shaft 221, the size of the anti-detachment member 222 being larger than the diameter of the rotating hole 213.

[0049] To further improve the smoothness of the rotation of the rotating seat 200 along the fixed seat 210, an annular slide 214 coaxial with the convex ring 211 is provided on at least one surface of the fixed seat 210 corresponding to the rotating seat 200, and multiple rolling elements 223 are rotatably connected within the slide 214.

[0050] like Figure 3-4 As shown, in this embodiment, an annular slide 214 is provided on the surface of the fixed seat 210, and a plurality of rolling elements 223 are rotatably arranged on the rotating seat 200 at equal intervals along the circumference. So that after the rotating seat 200 is assembled on the fixed seat 210, the rolling elements 223 can roll along the annular slide, thereby improving the smoothness of the rotation of the rotating seat 200.

[0051] In this embodiment, the rotating base 200 includes two opposing support frames 224, and the fan assembly 100 is located between the two support frames 224. The fan assembly 100 includes a housing 110 and a fan unit 120. The housing 110 has an internal mounting cavity, and ventilation windows 111 are provided on both sides of the housing 110. The fan unit 120 is disposed within the mounting cavity. The fan blades are rotated by a motor, thereby driving the rapid flow of air to achieve air delivery.

[0052] In this embodiment, a rotating member 112 is provided between the support frame 224 and the housing 110. The rotating member 112 rotatably connects the support frame 224 and the housing 110. In this embodiment, the axis of the rotating member 112 is arranged in the horizontal direction, thereby enabling the fan assembly 100 to swing vertically along the rotating member 112. Figure 3-5 As shown, a swing motor 113 electrically connected to the electromagnetic receiving component 420 is also fixedly mounted on the support frame / housing 110. The swing motor 113 is drively connected to the housing 110 / support frame 224, driving the housing 110 to swing back and forth around the axis of the rotating component 112. In this embodiment, the rotating body can be a rotating shaft 221 or a rotating flange, thereby enabling the housing 110 and the support frame 224 to be rotated. The swing motor 113 can be fixedly mounted on the support frame 224 or on the housing 110, and its output shaft is connected to the housing 110 or the support frame 224 accordingly, so that the fan assembly 100 can swing in the up and down direction during the driving of the swing motor 113.

[0053] Through the technical solution provided by the utility model embodiment, the driving device drives the rotating base 200 to achieve uninterrupted, dead-angle-free 360° rotation along the surface of the fixed base 210. Simultaneously, based on the principle of electromagnetic induction, a wireless inductive power supply method is used to power the fan assembly 100, thereby enabling the fan to rotate without the need for a power cord. Therefore, the 360° rotation of the rotating base 200 is not interrupted by power cord interference during its rotation, achieving truly uninterrupted, dead-angle-free 360° rotation and meeting the user's air-blowing needs. Furthermore, the driving motor 310 drives the rotating base 200 through a transmission method where the driving gear 311 meshes with the convex ring 211. This provides higher stability during the rotation of the rotating base 200, ensuring no shaking or wobbling. Moreover, the gear transmission method ensures a larger output torque from the driving motor 310, increasing load capacity and guaranteeing the reliability of the rotation of the rotating base 200 and the fan assembly 100.
