Fan blade type holographic image display device

Abstract

The invention discloses a fan blade type holographic image display device which comprises a frame, fan blades and a control panel. The control panel is fixedly connected to the inner bottom face of the frame, the fan blades are fixedly connected to the periphery of the control panel, the upper surfaces of the fan blades and the control panel are provided with LED lamps, the lower surface of the frame is fixedly connected with a rotary base, the front side and the rear side of the rotary base are provided with through holes which mutually communicate, and an angle adjusting device is fixedly connected to the rotary base through the through holes. The angle adjusting device comprises a holder, two fixed bases and a first rotating shaft, the portions, close to the front and rear sides, of theupper surface of the holder are fixedly connected with the two fixed bases correspondingly, and the front and rear sides of the two fixed bases are provided with circular holes which mutually communicate. By means of the cooperation of the structure, the effect that the angle and the height of the fan blade type holographic image display device are adjustable is achieved, and a user can watch images and store the fan blade type holographic image display device conveniently.

Description

technical field [0001] The invention relates to the technical field of image display, in particular to a fan-type holographic image display device. Background technique [0002] In the field of industrial cooling, fans are used to dissipate heat because some devices generate a lot of heat (such as computer graphics cards). A traditional fan includes: a bracket, a fan blade and a motor, and the motor drives the fan blade to rotate. At present, in order to improve the visual effect of the fan, some LED light-emitting lamps are usually installed on the bracket. When the fan is working, these LED light-emitting lamps will emit light at the same time, thereby improving the visual effect of the fan. However, the luminous effect of LEDs is limited, and it is difficult to meet the needs of consumers. On the other hand, after the human body's vision stops the visual stimulation of external objects, the image sensation on the retina of the eye will not disappear immediately, and it ...

Problems solved by technology

For example, the Chinese patent CN207609586U discloses a holographic phantom imaging fan. The device distributes a row of luminous lights on the high-speed rotating fan blades to control the light-emitting frequency of each luminous lamp, so that the fan blades will present a set holographic image when rotating. Phantom images, but the device is not positioned so that it is inconvenient for the user to view the images
