Problems solved by technology

[0003] Existing projector structures use large high-voltage halogen bulbs or high-pressure gas discharge bulbs as projection light source components, which must be coordinated with large high-voltage lamp circuits and heat dissipation systems, thus making the internal components of the projector complex and costly. Electricity, and the volume has become relatively bulky and bulky. In addition to being inconvenient to carry around and use, it is also not easy to install and use at any time. It has become a fixed equipment in conference rooms or indoors.
[0004] The above-mentioned existing projectors are not only bulky, but also not suitable for personal popularization, and users cannot realize portable use

Abstract

The invention provides a projector, which comprises an upper cover, a lower cover, a battery cover, a light machine and a circuit board. The lower cover comprises a light machine accommodating area and an electric accommodating area, wherein an electric connecting slot is formed between the light machine accommodating area and the electric accommodating area; a battery jar is concavely formed in the electric accommodating area; and the battery jar is communicated with the light machine accommodating area through the electric connecting slot. The light machine is accommodated in the light machine accommodating area, and the circuit board is fixedly arranged in the electric accommodating area. The upper cover is clamped on the lower cover from one side of the light machine accommodating area, and the battery cover is clamped on the battery jar of the lower cover. Through the minimized and compact configuration of each component in the projector, the projector can be held by a hand.

Description

technical field [0001] The invention relates to a projection device. Background technique [0002] The projector is widely used in the occasions of video playback, photo playback and presentation data playback, especially the projector can project and enlarge the display screen to a large-size display screen that cannot be achieved by existing TVs or monitors, making the projector suitable for A place with a large space and a large number of people. [0003] Existing projector structures use large high-voltage halogen bulbs or high-pressure gas discharge bulbs as projection light source components, which must be coordinated with large high-voltage lamp circuits and heat dissipation systems, thus making the internal components of the projector complex and costly. In addition to being inconvenient to carry around and use, it is also not easy to install and use at any time, and it has become a fixed equipment in conference rooms or indoors. [0004] The above-mentioned existi...
