An energy-saving slide projector that generates electricity by itself

Abstract

The invention discloses an energy-saving slide projector capable of generating power by itself. The energy-saving slide projector comprises a projector body, a projector used for projection is fixedlyinstalled on a heat conduction plate, second fan blades rotate to reduce the environment temperature, a second fan blade shaft rotates to drive the rotation of a third gear, the projector is in contact with the heat conduction plate while protection is performed to collect heat and transmit the heat into a generator for power generation so as to achieve recovery of electric energy, fan blades aredriven by transmission parts such as helical gears and gears to rotate for heat dissipation, a motor on a rotating shaft can be supplied with power by the generator in the projector body to achieve secondary utilization of electric energy while the projector body is subjected to heat dissipation to prevent the temperature of the projector body from too-high temperature and short circuit and achieve electric cycle; and moreover, due to the fact that the temperature of the environment is increased while heat dissipation is conducted, a user feels poor, and mist spray and an electric fan are designed to reduce the temperature in the environment.

Description

technical field [0001] The invention relates to the field of optical instruments, in particular to an energy-saving slide projector that generates electricity by itself. Background technique [0002] The industrial production of slide projectors started in 1845. The light source was also changed from candles at the beginning to oil lamps, gas lamps, and finally to electric light sources. [0003] Since the projection principle of the slide projector includes electrical energy emitting light, a large amount of heat is usually generated in the process of electrical energy emitting light. Cooling slide projector to solve the above problems. SUMMARY OF THE INVENTION [0004] The purpose of the present invention is to provide a self-generating energy-saving slide projector for overcoming the above-mentioned defects in the prior art. [0005] According to an embodiment of the present invention, a self-generating energy-saving slide projector includes a body, a water storage sp...

AI Technical Summary

Problems solved by technology

[0003] Since the projection principle of the slide projector includes electric energy luminescence, a large amount of heat is usually generated during the process of electric energy luminescence. Most of the reasons for repairing the slide projector on the market are that the temperature is too high during use and cause a short circuit, so we need an energy-saving and energy-saving Heat dissipation slide projector to solve the above problems
