Abstract

The invention relates to the field of electronic products, and specifically discloses a dust-proof conversion box of an electronic product. The dust-proof conversion box comprises a digital video conversion box, wherein the digital video conversion box is provided with a circuit switch and a cooling hole, a dust-proof device is arranged at the cooling hole of the digital video conversion box, andthe dust-proof device comprises an electric magnet and a thermal expansion block. When the digital video conversion box is not in a working state, the dust-proof device arranged at the cooling hole ofthe digital video conversion box prevents dust from entering the digital video conversion box; in the working state, the digital video conversion box generates electricity and heat, a covering is lifted automatically due to the principles of thermal expansion and contraction and electromagnetic effect, so that the digital video conversion box can dissipate heat as usual.

Description

technical field [0001] The solution relates to the field of electronic products, and specifically discloses a dust-proof conversion box for electronic products. Background technique [0002] A digital video conversion box (English: Set Top Box, referred to as STB), commonly known as a set-top box or a set-top box, is a device that connects a TV to an external signal source. It can convert the compressed digital signal into TV content, and display it on the TV so that users can watch digital TV programs on the existing TV, and can carry out interactive digital entertainment, education and commercial activities through the network. [0003] The digital video converter boxes on the market often have heat dissipation holes in order to reduce their own temperature during operation, but the heat dissipation holes will cause external dust to enter the digital video converter box. In the prior art, in order to prevent dust, a cover is often placed on the digital video converter box...
