Technical Field
[0001] This utility model relates to the field of set-top box technology, specifically a heat dissipation and moisture-proof set-top box. Background Technology
[0002] A set-top box is a device that connects a television set to an external signal source. It converts compressed digital signals into television content and displays it on the television. The signal can come from cable TV, satellite dish, broadband network, and terrestrial broadcast. In addition to the images and sound that analog television can provide, set-top boxes can also receive digital content, including electronic program guides and Internet web pages.
[0003] After prolonged use, the internal electronic components of a set-top box generate heat. While conventional set-top box casings have ventilation holes, relying solely on natural ventilation for heat dissipation is limited and easily leads to moisture accumulation, causing internal dampness. Prolonged high temperatures can reduce the lifespan of internal electronic components. Patent CN220511169U discloses a heat-dissipating and moisture-proof set-top box, including a set-top box with a heat dissipation mechanism. This heat-dissipating and moisture-proof set-top box features an air inlet and an air outlet. An intake fan is located in the air inlet, and an exhaust fan is located in the air outlet. During use, the intake fan, in conjunction with the air inlet, quickly introduces outside air into the set-top box, while the exhaust fan, in conjunction with the air outlet, extracts heat from the set-top box. This accelerates airflow within the set-top box, thereby improving heat dissipation efficiency and preventing internal moisture buildup. While the aforementioned patent improves heat dissipation and ventilation, it uses two fans on each side for ventilation, which increases both the cost of heat dissipation and dehumidification and the energy consumption of the set-top box, thus its practicality needs to be improved. Utility Model Content

[0008] As a preferred embodiment of this utility model, the set-top box body is equipped with control buttons and a display screen, and the control buttons and the display screen are embedded in the surface of the set-top box housing.
[0009] As a preferred embodiment of this utility model, the fixing strip is fixedly installed in the middle position of the bottom inside the set-top box housing and divides the bottom area inside the set-top box housing, and the two second protective nets are respectively located on both sides of the fixing strip.
[0010] As a preferred embodiment of this utility model, the first protective net, the first dustproof net, the second protective net, and the second dustproof net are all made of metal.
[0011] Compared with the prior art, this utility model provides a heat dissipation and moisture-proof set-top box, which has the following features:
[0012] Beneficial effects:
[0013] 1. This heat-dissipating and moisture-proof set-top box, through the design of ventilation channels and the cooperation of the second and first protective nets, uses only one fan to achieve comprehensive heat dissipation for the set-top box body. Simultaneously, air circulates throughout the set-top box casing, preventing moisture accumulation inside the casing and achieving a heat dissipation and moisture-proof effect. Furthermore, the set-top box casing also protects the set-top box body from impact damage. In this way, the set-top box body can reduce heat dissipation energy consumption while improving the practicality of the device.
[0014] 2. This heat dissipation and moisture-proof set-top box uses magnetic blocks to install the first and second dustproof screens, which effectively prevents external dust and debris from entering the set-top box housing. It also protects the set-top box from disassembly and cleaning. The design of the fixing strip allows external air to flow from both sides of the fixing strip towards the side of the set-top box body when it enters the set-top box housing through the second protective screen, forming two airflow forces that do not conflict, further improving the efficiency and stability of heat dissipation of the set-top box body.

Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.
[0020] Example 1
[0021] Please see Figure 1-3 In this embodiment: a heat dissipation and moisture-proof set-top box includes a set-top box housing 1, a fixing strip 8 is fixedly installed on the bottom of the inner side of the set-top box housing 1, a set-top box body 7 is fixedly installed on the top of the fixing strip 8 and inside the set-top box housing 1, a ventilation channel 10 is formed between the set-top box housing 1 and the set-top box body 7, a first protective net 2 is embedded and fixedly installed on the top of the set-top box housing 1, a symmetrically distributed second protective net 5 is embedded and fixedly installed on the bottom of the set-top box housing 1, a fan 9 is installed on the top of the set-top box body 7 and below the first protective net 2, and symmetrically distributed support blocks 15 are fixedly installed at the four corners of the bottom of the set-top box housing 1.
[0022] In use, fan 9 is connected to the internal power supply of the set-top box body 7. When the set-top box body 7 is started, fan 9 will also start simultaneously. At this time, outside air enters the ventilation channel 10 through the second protective mesh 5, then passes between the set-top box housing 1 and the set-top box body 7, and is exhausted through the first protective mesh 2. This design, through the ventilation channel 10 and the cooperation of the second and first protective meshes 5, allows for comprehensive heat dissipation of the set-top box body 7 using only fan 9. Simultaneously, air circulates within the set-top box housing 1 to all corners, preventing moisture buildup inside the housing and achieving both heat dissipation and moisture protection. Furthermore, the set-top box housing 1 also protects the set-top box body 7 from impact damage. Thus, the set-top box body 7 reduces energy consumption while improving the device's practicality.
[0023] In a preferred embodiment, the top of the set-top box housing 1 is provided with a top groove 13, the first protective net 2 is fixedly installed on the inner side of the top groove 13, and the bottom of the set-top box housing 1 is provided with symmetrically distributed bottom grooves 14, the second protective net 5 is fixedly installed on the inner side of the bottom groove 14; thus ensuring the stability of the installation of the first protective net 2 and the second protective net 5.
[0024] In a preferred embodiment, multiple symmetrically distributed magnetic blocks 4 are fixedly installed on the top of the first protective net 2 and the bottom of the second protective net 5, respectively. A first dustproof net 3 is snapped onto the inner side of the top groove 13 and above the first protective net 2, and a second dustproof net 6 is snapped onto the inner side of the bottom groove 14 and below the second protective net 5. The magnetic blocks 4 are adsorbed onto the surfaces of the first dustproof net 3 and the second dustproof net 6. By using the magnetic blocks 4 to install the first dustproof net 3 and the second dustproof net 6, external dust and debris can be effectively blocked from entering the set-top box housing 1, and disassembly can be prevented for cleaning.
[0025] Example 2
[0026] Please see Figure 1-3 In this embodiment: a control button 11 and a display screen 12 are installed on the surface of the set-top box body 7. The control button 11 and the display screen 12 are embedded and snapped onto the surface of the set-top box housing 1, thereby improving the convenience and safety of the device.
[0027] In a preferred embodiment, the fixing strip 8 is fixedly installed in the middle of the bottom inner side of the set-top box housing 1 and divides the bottom area of the inner side of the set-top box housing 1. The two second protective nets 5 are located on both sides of the fixing strip 8. This allows the outside wind to flow from both sides of the fixing strip 8 toward the side of the set-top box body 7 when it enters the interior of the set-top box housing 1 through the second protective nets 5, forming two streams of airflow without conflict, further improving the efficiency and stability of heat dissipation of the set-top box body 7.
[0028] As a preferred embodiment, the first protective net 2, the first dustproof net 3, the second protective net 5, and the second dustproof net 6 are all made of metal, which facilitates their installation and maintenance and improves the stability of the structure.
