Description

Technical Field

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

[0002] With the continuous development of consumer electronics and smart homes, fans are no longer just responsible for traditional air circulation and cooling functions; they are also evolving towards more aesthetically pleasing, intelligent, and interactive features. Among these, bladeless fans are favored by many users due to their gentle airflow, high safety, and simple appearance. Bladeless fans typically employ a ring-shaped air outlet structure and utilize airflow multiplication technology to achieve stable air delivery, making them a common device in modern home environments.

[0003] However, existing bladeless fans lack visual interaction capabilities, and users' demand for visual information display and interactive experience is increasing. If users want to obtain both air conditioning and visual information display effects at the same time, they often need to purchase and arrange two types of equipment separately, which increases costs and affects the aesthetics and integration of the space layout. Utility Model Content

[0004] The main purpose of this invention is to provide a bladeless fan with holographic display, which aims to solve the problems of independent structure, separate functions, and low integration between fan-type devices and visual display devices.

[0006] A base, on which an air inlet is provided;

[0007] A fan, wherein the fan is disposed within the base;

[0008] A bladeless fan head is mounted on the base. The bladeless fan head includes an annular air outlet structure, which forms a central opening. A holographic display component is provided at the central opening for displaying dynamic images in the central area of ​​the bladeless fan head.

[0009] In one possible implementation, the holographic display component includes:

[0010] A transparent bottom shell, which is fixedly connected to the inner wall of the air outlet structure;

[0011] A rotating mechanism connected to the center of the transparent bottom shell;

[0012] Rotating blades, the rotating blades being driven and connected to the rotating mechanism;

[0013] A drive circuit board is connected to one side of the rotating blade. Several LED beads are electrically connected to the drive circuit board, which is used to control the on / off state, brightness, and color of the LED beads.

[0014] In one possible implementation, the holographic display component further includes a control module disposed within the base for storing image data or receiving wirelessly transmitted content.

[0015] In one possible implementation, the holographic display component further includes a transparent cover that covers the transparent base.

[0016] In one possible implementation, the bladeless fan head further includes an arc-shaped bracket, with its two ends connected to both sides of the air outlet structure and its middle section connected to the base.

[0024] To make the objectives, technical solutions, and advantages of this application clearer, the following detailed description is provided in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative and not intended to limit the scope of this application.

[0025] To address the problems in the background art, this utility model proposes a bladeless fan with holographic display, comprising:

[0026] Base 10, on which an air inlet 11 is provided;

[0027] A fan, wherein the fan is disposed within the base 10;

[0028] The bladeless fan head 20 is mounted on the base 10. The bladeless fan head 20 includes an annular air outlet structure 21, which forms a central opening. A holographic display component 30 is provided at the central opening for displaying dynamic images in the central area of ​​the bladeless fan head 20.

[0029] like Figure 1 and Figure 2 As shown, a bladeless fan with a holographic display includes: a base 10, a fan (not shown), a bladeless fan head 20, and a holographic display component 30 disposed in the central area of ​​the bladeless fan head 20. The base 10 is the main body structure located at the bottom of the device, supporting the entire bladeless fan assembly. An air inlet 11 is provided on the base 10 for drawing in external air. The air inlet 11 can be located on the bottom, side, or circumferentially distributed of the base 10, facilitating air intake from the outside. The fan, a centrifugal or axial fan, is disposed inside the base 10. Its air inlet is connected to the air inlet 11, and its air outlet is connected to the air outlet structure 21 of the bladeless fan head 20, providing a stable airflow. The fan is driven by a motor and connected to a control module, allowing for adjustable wind speed. The bladeless fan head 20 is mounted on the top of the base 10, preferably connected to the base 10 via an arc-shaped bracket 40, and is suspended. The bladeless fan head 20 includes an annular air outlet structure 21, which has a hollow annular structure with multiple slit-type air outlets on its outer ring and an internal air channel for receiving high-pressure airflow from the fan. The air is accelerated within the annular channel by a guide structure and ejected from the air outlets, forming a continuous and uniform airflow. The annular air outlet structure 21 forms a central opening, which is a cavity structure. The holographic display component 30 is disposed in this central opening and can be fixedly connected to the inner circumference of the annular structure via an integrated support structure. The holographic display component 30 includes a rotation drive mechanism, a rotation arm, an LED display module, a control circuit, and a power connection component. By driving the rotation and controlling the timing of the LED pixels' illumination, a naked-eye visible dynamic image can be formed in the center of the fan head, preferably a 3D dynamic display effect, used to enhance the visual experience or for information display.

[0030] In one possible implementation, the holographic display component 30 includes:

[0031] A transparent bottom shell 31 is fixedly connected to the inner wall of the air outlet structure 21;

[0032] Rotating mechanism 32, which is connected to the center of the transparent bottom shell 31;

[0033] Rotating blade 33, the rotating blade 33 being driven and connected to the rotating mechanism 32;

[0034] A drive circuit board 34 is connected to one side of the rotating blade 33. A plurality of LED beads 35 are electrically connected to the drive circuit board 34. The drive circuit board 34 is used to control the on / off state, brightness and color of the LED beads 35.

[0035] like Figure 2 As shown, in this example, the transparent base shell 31, made of transparent polycarbonate (PC) or acrylic (PMMA), supports the base 10 of the holographic structure. Its outer edge is fixed to the inner wall of the central opening of the bladeless fan head 20 via slots, screws, etc., ensuring the rotating component is centered and stable. This base shell possesses both mechanical strength and good optical transmittance, facilitating visual observation. The rotating mechanism 32, located at the center of the transparent base shell 31, includes a micro-motor, shaft, bearings, etc., and drives the rotating blades 33. This mechanism provides the necessary high-speed rotational power for the holographic display, and its operational stability and lifespan significantly affect the image quality. The rotating blades 33 are connected to the output shaft of the rotating mechanism 32 and are typically one or two rod-like structures made of lightweight materials to reduce rotational inertia and improve safety. The rotating blades 33 serve as the support component for the LED display circuit board. The drive circuit board 34 is mounted on the upper surface or side of the rotating blades 33 and is used to control the display. The circuit board integrates several high-brightness LED beads 35. Through precise control of the lamp bead illumination time, brightness, and color, a grating visual persistence image is formed during rotation. The driver circuit board 34 may also include an angle sensing module for precise synchronization of the displayed content.

[0036] In one possible implementation, the holographic display component 30 further includes a control module (not shown), which is disposed within the base 10 and is used to store image data or receive wirelessly transmitted content.

[0037] In this embodiment, the holographic display component 30 further includes a control module located inside the fan base 10. This control module includes the following functional components: a processor (MCU or ARM core) for processing image data and controlling display logic; an image storage unit, which can be local flash memory or a removable memory card, for storing preset image content; a wireless communication module supporting Bluetooth, Wi-Fi, etc., to enable data interaction with external devices such as mobile apps and computers, thereby receiving dynamic images or video materials; and a power management module to supply power to the rotating part, possibly through a slip ring, wireless power supply, or other rotating electrical connection methods. The control module communicates with the rotation drive circuit via wired or wireless means to dynamically control the content, color, frame rate, and other information displayed by the LED beads 35, enabling remote updates and intelligent control.

[0038] In one possible implementation, the holographic display component 30 further includes a transparent cover 36 that covers the transparent base shell 31.

[0039] like Figure 1 As shown, the holographic display assembly 30 further includes a transparent cover 36 to enhance structural safety and protective performance. This transparent cover 36 is located on the upper outer side of the transparent base shell 31, and is an arched or dome-shaped cover. It is made of transparent ABS or PC material, possessing high strength and heat resistance. The cover is fixed to the edge of the base shell by screws, clips, or adhesives to ensure sealing and shock resistance. The main function of this cover is to prevent external foreign objects (such as fingers, dust particles, etc.) from entering the rotating area, improving safety during use, and also preventing damage to the LED board or dust accumulation during rotation that could lead to display abnormalities. The cover has high optical transmittance and does not significantly interfere with image visibility.

[0040] In one possible implementation, the bladeless fan head 20 further includes an arc-shaped bracket 40, the two ends of which are respectively connected to the two sides of the air outlet structure 21, and the middle part is connected to the base 10.

[0041] In this embodiment, the arc-shaped bracket 40 is made of metal or high-strength engineering plastic material, and has an overall arched or bow-shaped structure. Both ends of the bracket are fixedly connected to both sides of the annular air outlet structure 21 of the bladeless fan head 20, and the fixing method can be clips, screws, or thermal riveting. The middle part of the bracket is connected to the top central axis of the fan base 10, and a mechanical connection can be achieved through slot fitting or screw fixing. The bracket may also have wiring channels inside or on its surface to guide power lines and signal lines from the base 10 to the fan head and holographic display component 30. This structure combines load-bearing support and wiring functions, ensuring structural strength and fan head stability while also facilitating integrated design and enhancing the overall aesthetics of the device.
