Problems solved by technology

[0004] In view of the related technologies mentioned above, the inventor believes that while the set-top box is dissipating heat, the dust will enter the set-top box through the heat dissipation holes, and the dust in the casing will be adsorbed on the electronic components. When the dust exceeds a certain amount, it will Affect the normal operation of electronic components

Embodiment 1

[0032] The embodiment of the present application discloses an automatic dust removal intelligent set-top box. refer to figure 1 , the set-top box includes a casing 1 and a fan 7 installed in the casing 1, the side wall of the casing 1 has a cooling hole 2, the cooling hole 2 is equipped with a dust collection net 3, and the casing 1 is also equipped with a cooling hole Negative ion generating components that pass negative ions at 2 places.

[0033] refer to figure 1 , there is an air outlet hole (not shown in the figure) on the casing 1, and the fan 7 is set facing the air outlet hole. The casing 1 is surrounded by six boards to form a rectangular box, and the adjacent boards are fixed by bolts. The dust collection net 3 is composed of several hollow negative ion rods intersecting each other to form a mesh. There are a number of micropores (not shown in the figure) on the negative ion rods, and the negative ion generating components include tourmaline (not shown in the figur...

Embodiment 2

[0042] Different from Embodiment 1, the inner wall of the collection box 4 is coated with glue or self-adhesive, so as to stick the dust falling from the dust collection net 3 .

[0043] The implementation principle of an automatic dust removal intelligent set-top box in the embodiment of the present application is as follows:

[0044] Start the set-top box, the fan 7 starts to draw the wind into the casing 1 from the cooling hole 2, and at the same time, the tourmaline produces negative ions, which combine with the dust at the cooling hole 2, so that the dust at the cooling hole 2 settles, and Fall into the collection box 4 facing the opening of the dust collection net 3, reduce the dust in the air entering the casing 1 from the cooling hole 2, reduce the impact of the dust on the electronic components in the casing 1, and improve the set-top box. Long service life, but also reduce the trouble of cleaning up the dust later.

[0045] By placing tourmaline in the negative ion ...

Abstract

The invention relates to an intelligent set top box capable of automatically removing dust, which comprises a machine shell and a fan installed in the machine shell, heat dissipation holes are formed in the side wall of the machine shell, a dust collection net is installed on the heat dissipation holes, a negative ion generation assembly for introducing negative ions to the heat dissipation holes is further installed in the machine shell, and a collection box right facing an opening of the dust collection net is installed in the machine shell. The negative ion generation assembly is installed in the machine shell, and negative ions generated by the negative ion generation assembly fall to the dust collecting net, so that dust in air entering the machine shell from the heat dissipation holes is settled under the action of the negative ions and falls into the collection box placed in the machine shell to be collected; therefore, less dust is contained in the air entering the casing, and the dust is not easy to influence electronic components in the casing.

Description

technical field [0001] This application relates to the field of digital television, in particular to an intelligent set-top box with automatic dust removal. Background technique [0002] A digital video converter box, commonly called a set-top box or set-top box, is a device that connects a television to 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] The set-top box includes a casing and a circuit board installed in the cas...
