Abstract

The present invention provides an electronic device. The electronic device comprises a lens, a shell, a guide plate, a lens cap and a fan, wherein the lens, the guide plate and the fan are disposed within the shell, a first opening and a second opening are disposed in the shell; the lens can project light to an imaging area through the first opening; and when the lens cap covers the first opening, the fan can form a wind flow between the second opening and the fan. The airflow can flow through the lens cap by means of the guide plate so as to dissipate heat for the lens cap, so that dangers caused by temperature increase as the lens cap covers the lens are prevented, and there is no need to decrease projection brightness or to restart the electronic device, thereby improving user experience and achieving higher reliability.

Description

technical field [0001] The invention relates to an electronic device, in particular to an electronic device capable of effectively dissipating heat from a lens. Background technique [0002] The lens cover of the projection device can be generally divided into a detachable lens cover and a sliding lens cover. The sliding lens cover is built on the body, which is easy to use and not easy to lose. However, there is a problem with this form of lens cover. When the projection device is in use (that is, the projection screen), if the lens cover covers the lens, a large amount of strong light that should be projected will be absorbed by the lens cover and generate high heat. When the user touches the lens cover that has absorbed heat, it will cause burns, and in severe cases, the lens cover will be melted and deformed, and even the projection lens will be damaged. [0003] The solution in the prior art is to detect the lens cover through various sensors. When it is detected that ...
