Description

Technical Field

[0002] A TV box is a device that can transmit signals to a TV set, which then allows the TV set to play programs. The outer shell of a TV box is usually made of plastic or metal. Its main function is to protect the circuit boards and components inside the TV box from the influence of the external environment.

[0003] Reference publication number CN216721766U discloses a hanging network TV box that is easy to dissipate heat. The TV box body can be conveniently hung by a hanging adjustment structure without being limited by the distance between the two hanging points. At the same time, the pre-embedded bolts in the wall can be locked to prevent the TV box body from falling and causing accidental injuries. The heat inside the TV box body can be continuously discharged from the TV box body by a cooling structure to ensure that the TV box body works at a suitable temperature. The TV box body is hung more stably and beautifully by cooperating with the supporting structure and the hanging adjustment structure. However, the following problems still exist:

[0004] In actual use of the above device, although the purpose of heat dissipation is achieved through a cooling mechanism, the cooling mechanism evaporates the heat to the outside of the TV box through cooling leaves. In order to allow air to flow, openings need to be provided on the TV box. However, the openings will cause dust to enter, which will cause the dust to be adsorbed onto the electrical components inside the TV box, and then the electrical components will be unable to volatilize heat due to the adsorption of dust, thereby reducing the heat dissipation effect.

[0005] Therefore, we have proposed a shell structure for a TV box that can well solve the above problems. Utility Model Content
