Digital video player for network live broadcast

Abstract

The invention relates to the technical field of digital video players, in particular to a digital video player for network live broadcast, which comprises a protective shell, a projection device is fixedly mounted on the inner wall of one side of the protective shell, a heat conducting plate is fixedly connected to the outer wall of the projection device, and a water disc is fixedly connected to the outer wall, away from the protective shell, of the heat conducting plate. Cooling liquid is arranged in the water disc, an inserting rod is rotationally connected to the center of the end, away from the heat conducting plate, of the water disc, a first sleeve is rotationally connected to the center of the inner wall of the water disc, stirring blades are fixedly connected to the outer wall of the first sleeve, and fan blades are fixedly connected to the outer wall of the end, away from the water disc, of the first sleeve. The stirring blades in the water disc are driven to rotate through the insertion rod, so that the flow speed of cooling liquid is increased, the cooling speed of the heat conduction plate is increased through uniform heat absorption of the cooling liquid, and when the projection device stops working, dust on the surface of a metal plate can be cleaned through resilience of the first spring; therefore, the burden of manual regular cleaning is relieved.

Description

technical field [0001] The invention relates to the technical field of digital video projectors, in particular to a digital video projector for network broadcasting. Background technique [0002] The digital cinema machine applies the digital micromirror switch device DMD—digital optical switch array and digital signal processing technology, and adopts the new mode of digital film projection of the digital light processing technology DLP, which replaces the film image reproduction mode of the traditional film film projector, and realizes no film show. [0003] However, after the existing digital projector has been used for a period of time, its interior will generate high heat and some dust will enter, and it is necessary to manually carry out dust treatment on the interior of the projector and the lens, so as to prevent dust from affecting the performance of the projector. It works normally, but manual cleaning is cumbersome, and the internal parts of the projector may be ...

[0003] However, after the existing digital projector has been used for a period of time, its interior will generate high heat and some dust will enter, and it is necessary to manually carry out dust treatment on the interior of the projector and the lens, so as to prevent dust from affecting the performance of the projector. It works normally, but manual cleaning is cumbersome, and the internal parts of the projector may be damaged during the cleaning process
