Description

Technical Field

[0001] This utility model relates to the field of fan technology, and in particular to a holographic fan. Background Technology

[0002] With the rapid development of display technology, the combination of holographic projection and irregularly shaped screens has shown great potential in fields such as stage art, commercial exhibitions, and architectural projection. Traditional display solutions typically rely on a single technology to achieve imaging, for example:

[0003] Holographic fan solutions generate levitation images using the persistence of vision effect through high-speed rotating LED strips. However, their imaging range is limited, making it difficult to cover complex backgrounds, and their ability to coordinate dynamic content with static backgrounds is insufficient. For example, a cooling fan disclosed in 201921468806.8 has an imaging effect. It includes a wireless charging transmitter module and a wireless charging receiver module, also known as a power supply coil and a power receiving coil. These are common components in electronic devices. Their core function is to convert an external alternating magnetic field into an induced current through electromagnetic induction, thereby achieving contactless transmission of electrical energy or signal control, thus forming the power supply and data command channel for the LED strip.

[0004] Appendix to the patent Figure 2 As can be clearly seen, the wireless charging transmitter module and the wireless charging receiver module have a circular and flat structure. This structure has the problems of small contact area and low power generation. When it is used with a fan with a large diameter, the power generation is insufficient to meet the normal operation of the fan. Utility Model Content

[0005] The main purpose of this invention is to solve the problem that flat power generation coils generate little electricity and are difficult to support the normal operation of large-diameter fans.

[0006] To achieve the above objectives, this utility model proposes a holographic fan, comprising:

[0007] include:

[0008] Sector frame;

[0009] Fan blades, the fan blades being pivotally mounted to the fan frame;

[0010] A drive mechanism, located on the fan frame, is used to drive the fan blades to rotate;

[0011] A light strip is provided on the fan blade and can rotate with the rotation of the fan blade;

[0012] The power supply coil and the power receiving coil are provided. The power supply coil is sleeved on the drive mechanism, and the power receiving coil is located on the fan blade and electrically connected to the lamp strip. The power supply coil and the power receiving coil are in a ring shape, and the power receiving coil is located inside the power supply coil.

[0013] Preferably, the fan frame is fixed with a support platform, and the drive mechanism is disposed on the support platform.

[0014] Preferably, a mounting bracket is also provided, which is detachably and fixedly mounted on the fan frame. The top of the mounting bracket is provided with a mounting groove, and the drive mechanism is located in the mounting groove. The fan blade is pivotally mounted on the mounting bracket through the drive mechanism. The middle part of the fan blade is provided with an annular insertion part near the mounting bracket. The drive mechanism is located in the insertion part. The outer peripheral wall of the insertion part and the inner side wall of the mounting groove are spaced apart to form an annular receiving space. The power supply coil and the power receiving coil are located in the receiving space.

[0015] Preferably, the outer peripheral wall of the insertion part is provided with a locking position for securing the receiving coil.

[0016] Preferably, it also includes a PCB board electrically connected to the power supply coil. The PCB board is disposed on the support platform and is vertically spaced opposite to the bottom wall of the mounting frame. The support platform is provided with screws that pass through the PCB board and are screwed into the mounting frame to lock the mounting frame and the PCB board together on the support platform.

[0017] Preferably, the bottom wall of the mounting groove is provided with a first wire groove through which the mounting bracket passes, and the connecting end of the power supply coil passes through the first wire groove and is electrically connected to the PCB board.

[0018] Preferably, a receiving groove is provided on the side of the fan blade shaft core away from the mounting groove, and a second wire groove is formed through the bottom wall of the receiving groove and communicates with the mounting groove. The connection end of the receiving coil passes through the second wire groove and is electrically connected to the control component of the light strip.

[0019] Preferably, the fan blade is detachably fixed to a housing, the light strip is detachably inserted into the housing, and the housing has an elongated clearance groove on the side away from the fan blade to expose the LED beads on the light strip. The housing has a cavity for accommodating the control component at a position corresponding to the lower part of the light strip.

[0020] This invention powers the drive mechanism by supplying power to the transmitting coil via an external power source. Simultaneously, the receiving coil and transmitting coil work together to achieve a contactless transmission effect, enabling power supply and data transmission for the light strip. This also achieves fan blade rotation and imaging effects. The receiving and transmitting coils are ring-shaped; the greater the thickness, the larger the contact area and the greater the power generation, effectively meeting the operational needs of larger diameter fans, such as those with diameters of 12cm, 15cm, or 20cm. The installation of the receiving and transmitting coils makes reasonable use of the holographic fan's installation space, ensuring the final holographic fan is not bulky.
