Double-reflection type liquid crystal display (LCD) projector

A turbofan is electrically connected with an external power supply, light emitted by a light source is reflected by a lower light source reflecting lens, is gathered by an integrated light gathering cup and forms polarized light through a heat insulation polarization filter, infrared light is filtered out, and then the light reaches a first film lens. Multiple beams of parallel light are formed through the first film lens, generate images after passing through the LCD, are focused after passing through the second film lens, and finally reach the lens after being reflected by the upper imaging reflecting lens; an upper imaging reflection lens and a lower light source reflection lens in the light path system form a double-reflection type optical system, so that the light path structure is effectively changed, and the problems that a traditional projector in the prior art is single in structure, large in size, low in space utilization rate and the like are solved. And a product mechanism carrying the double-refl
