Description

a projector

technical field

The invention relates to the field of projection equipment, in particular to a projector.

Background technique

Projectors are now divided into two categories, one is conference and home, and the other is portable. Meetings and households need to be plugged in with 220V power supply to be used, and various connection lines need to be plugged in to input signals to play movies or cast screens. If you take it outdoors or if it is out of reach of home appliances, it cannot be used, and its use is very limited. The second category, Xiaoxiao comes with its own battery, which is easy to carry, does not need to plug in many cables, and can be used in various scenarios without restrictions, but the battery life is a big disadvantage. It can only be used for 1-3 hours, and the battery is out. , must be charged to use.

Contents of the invention

In view of the above-mentioned deficiencies in the prior art, the present invention provides a projector, which can meet all projection power supply requirements through the energy storage power supply module of 220V power supply, 5V power supply module, or 12V power supply module, and the power supply of the energy storage battery Large capacity provides long enough battery life.

In order to achieve the above-mentioned purpose of the invention, the technical scheme adopted in the present invention is:

A projector, comprising: an outer casing, a control board is vertically installed inside and on the side of the outer casing, the control board is electrically connected to a horizontally placed wireless charging board through a wire, and the wireless charging board is electrically connected to a wireless charging board through a wire. On the control board, a battery separator is placed above the battery, an AC board electrically connected to the battery is placed above the battery separator, and the AC board is electrically connected to the projector placed on the upper right side through a wire. The upper surface of the control board is equipped with a 5V power supply module electrically connected to the wireless charging board, battery, AC board and projector control board, a 12V power supply module and a 220V power supply module on the AC board, and the two sides of the housing are respectively installed with the control board and the battery. The AC board of the illuminating lamp connected with the electric wire of the control board is electrically connected with the cooling fan, and the switch key is arranged on the outer casing.

Compared with the prior art, the present invention has the advantages that all projection power supply requirements can be met through the energy storage power supply 220V power supply module, 5V power supply module, or 12V power supply module, and the large capacity of the energy storage battery provides a long enough battery life. Through the power supply characteristics of the energy storage power supply, let the projector group be inside the energy storage power supply, and then connect it to the energy storage power supply to supply power. It can supply power to the loudspeaker, the effect, and the projector can be used for KTV in the wild.

As an improvement, the outside of the outer casing is a projector lens of a projector, and a handle is hinged above the outer casing.
