Set top box with dustproof function

Abstract

The invention relates to a set top box with a dustproof function, the set top box comprises a main body and a plurality of plugging ports, the set top box also comprises a dustproof mechanism and a dedusting mechanism, the dustproof mechanism comprises a fixed magnetic strip and a plurality of dustproof assemblies, and each dustproof assembly comprises a rotating unit, a dustproof plate, a transmission disc, a first bearing, a transmission shaft and a transmission unit. The dust removal mechanism comprises a driving assembly, a connecting assembly, a fixing ring, two fixing rods and two dust removal assemblies, each dust removal assembly comprises a dust removal rod, a rolling ball, a first spring and two telescopic rods, the set top box with the dustproof function realizes the function of shielding the insertion port through the dustproof mechanism, so that dust in air cannot be attached to the insertion port, the phenomenon of poor plugging is avoided, and the reliability of the equipment is improved. Through the dust removal mechanism, the function of removing dust above the main body is achieved, the situation that the heat dissipation effect of the main body is affected due to dust accumulation above the main body is prevented, and then the reliability of the equipment is improved.

Description

technical field [0001] The invention relates to the field of digital technology equipment, in particular to a set-top box with dustproof function. Background technique [0002] Digital video conversion box (Set Top Box) referred to as STB, usually called a set-top box or set-top box, is a device that connects a TV with an external signal source. It can convert the compressed digital signal into TV content and display it on the TV. Signals can come from cable, satellite dishes, broadband networks, and terrestrial broadcasts. The content received by the set-top box is to be able to receive digital content, including electronic program guides, Internet web pages, etc., in addition to the images and sounds that can be provided by analog TV. It enables users to watch digital TV programs on existing TV sets, and conduct interactive digital entertainment, education and commercial activities through the network. [0003] When the existing set-top box works for a long time, a larg...

AI Technical Summary

Problems solved by technology

[0003] When the existing set-top box works for a long time, a large amount of dust and impurities are easy to accumulate on the top of the main body, which easily affects the heat dissipation effect of the main body, thereby affecting the service life of the existing set-top box and reducing the practicability of the existing set-top box Not only that, but the sockets of the existing set-top boxes are usually exposed, causing a large amount of dust and impurities to accumulate in the sockets. When the cable is inserted into the socket, dust and other impurities will easily lead to poor connection of the cable, thus affecting the transmission signal. work impacts, reducing the reliability of existing set-top boxes
