Problems solved by technology

[0003] At present, the heat dissipation performance of the set-top boxes on the existing market is poor, which causes the internal components to be easily damaged, and the set-top boxes are not placed stably, and they are easy to fall and cause damage. During the use of the set-top boxes, the waterproof performance is poor. It is difficult to maintain and can only be replaced, resulting in waste of resources and loss of property, reducing the user experience and failing to meet the user's needs.

Abstract

The invention discloses a waterproof heat dissipation device for a set top box, and relates to the technical field of set top box protection. The waterproof heat dissipation device comprises a protective shell, the top of the protective shell is provided with a shell cover, the top of the shell cover is fixedly connected with symmetrically distributed top rods, the top of each top rod is fixedly connected with a baffle plate, the inner side of the shell cover is fixedly connected with a positive plate, the inner side of the shell cover is fixedly connected with a negative plate, the inner side of the shell cover is provided with water guide cavity channels which are symmetrically distributed left and right, and the inner side of the protective shell is slidably connected with a placement plate. According to the device, through cooperation of the positive plate, the negative plate, a magnetic block, a plug and the like, when water is splashed to the top of the protective shell, the water is collected to the top of the shell cover, the positive plate and the negative plate are communicated, the magnetic block can be electrified to generate magnetism to be adsorbed, a sliding block drives a mounting plate and the plug to move, the plug blocks ventilation holes, and water is prevented from entering the inner side of the protective shell from the ventilation holes to damage the set top box.

Description

technical field [0001] The invention relates to the technical field of set-top box protection, in particular to a waterproof and heat-dissipating device for a set-top box. Background technique [0002] A digital video conversion box is usually called a set-top box or a set-top box. It is a device that connects a TV to an external signal source. It can convert compressed digital signals into TV content and display them on the TV. The signal can come from cable, satellite Antennas, broadband networks and terrestrial broadcasting, the content received by the set-top box is not only the image and sound that can be provided by analog TV, but also the data content that can be received, including electronic program guides, Internet pages, subtitles, etc. Watch digital TV programs on board, and conduct interactive digital entertainment, education and commercial activities through the network. [0003] At present, the heat dissipation performance of the set-top boxes on the existing...
