Abstract

The invention belongs to the technical field of projectors, discloses a projector for teaching, and solves the problems that projectors for teaching in the current market are fixed in installation position and poor in applicability to projections with different heights. The projector comprises a projector body, ventilation openings are formed in the two sides of the front end of the projector body, storage grooves are formed in the two sides of the projector body, motors are installed at the bottoms of the storage grooves through installation frames, and propellers are installed at the output ends of the motors. The projector has the beneficial effects that: when the projector is not unfolded, the motors drive the propellers to exchange air in the projector body, and through cooperation of the ventilation openings, better air exchange is facilitated, and the heat dissipation effect is improved; and when the projector is unfolded, the motors drive the propellers to rotate, and then the projector body is driven to perform up and down movement, hovering and vertical taking off and landing, so that the projector body is suitable for use at different heights, and the applicability is improved.

Description

technical field [0001] The invention relates to the technical field of projectors, in particular to a projector for teaching. Background technique [0002] A projector is a device that can project images or videos onto a screen. It can be connected to a computer, VCD, DVD, game console, DV, etc. through different interfaces to play corresponding video signals. It is widely used in homes, offices, and schools. and entertainment venues. [0003] Currently, the teaching projectors on the market have a fixed installation position, have poor applicability for projection at different heights, can only be placed on a flat surface, and are inconvenient to adjust the tilt angle. Contents of the invention [0004] The invention proposes a teaching projector, which solves the problem that the teaching projectors currently on the market have a fixed installation position and poor applicability for projection at different heights. [0005] The technical solution of the present invent...
