[0002] At present, the monitor is the I / O device of the computer, that is, the output device. It is a display tool that displays certain electronic files on the screen through a specific transmission device. It can be divided into cathode ray tube monitors (CRT), plasma displays PDP, and liquid crystal displays LCD. High-performance monitors, such as game monitors, workstation monitors, etc., usually have more powerful processing capabilities and higher refresh rates. During long-term use, the electronic components inside the monitor will generate more heat. In the related technology, a cooling fan is needed to accelerate the heat dissipation and keep the monitor running within a suitable temperature range. If the heat is not dissipated in time, the heat accumulation will cause the monitor temperature to be too high, which will affect its normal operation or even damage it.

[0037] Reference Figure 2A ventilation hole 12 is provided on the shell 1 , and the arrangement of the ventilation hole 12 facilitates the flow of gas in the shell 1 .

[0038] Reference Figure 4 and Figure 5 The heat dissipation assembly 21 includes an air supply pipe 211 and a heat dissipation fan 212. The air supply pipe 211 is fixedly connected to the housing 1, and one end of the air supply pipe 211 is close to the heat dissipation hole 11 (refer to Figure 3 ) direction, and the cooling fan 212 is installed in the air supply duct 211.

[0039] Reference Figure 3 and Figure 5 When the cooling fan 212 is working, the cooling fan 212 can suck the gas in the shell 1 into the air supply pipe 211, and make the gas flow toward the heat dissipation hole 11 through the air supply pipe 211, which is beneficial to improve the heat dissipation efficiency, so as to quickly dissipate the heat generated by the electronic components inside the shell 1 to the outside air.

[0040] In this embodiment, an air suction cover 2111 is provided at one end of the air supply pipe 211 away from the heat dissipation hole 11 , so as to facilitate the heat dissipation fan 212 to suck gas into the air supply pipe 211 .

[0041] Reference Figure 5 and Figure 6 , a plurality of adsorption components 22 are provided, and the adsorption components 22 include a connecting ring 221 and an activated carbon plate 222, and the activated carbon plate 222 is coaxially mounted on the connecting ring 221. In this embodiment, the activated carbon plate 222 is designed in a honeycomb shape, so that on the one hand, the contact area between the activated carbon plate 222 and the air is increased to improve the adsorption efficiency, and on the other hand, the gas can flow more evenly in the activated carbon plate 222 to reduce the resistance of the gas flow, thereby facilitating the improvement of the overall ventilation efficiency.

[0042] Reference Figure 6 A high-efficiency heat dissipation fan for a display screen includes an adjustment mechanism 4, which is arranged on a housing 1. The adjustment assembly includes a driving member 41, a turntable 42, and a movable assembly 43. The driving member 41 is installed on the housing 1, and the turntable 42 is rotatably connected in the housing 1 and fixedly connected to the output end of the driving member 41. In this embodiment, the driving member 41 is a motor, so that the driving member 41 can be used to drive the turntable 42 to rotate. In other embodiments, the driving member 41 can also be set as a handle.

[0043] The turntable 42 is provided with mounting holes 421, the number of which is equal to the number of the adsorption components 22, and the plurality of mounting holes 421 are evenly distributed around the axis of the turntable 42. A limiting ring 4211 is coaxially fixedly connected to the inner wall of each mounting hole 421, and the limiting ring 4211 is located on the side of the mounting hole 421 away from the driving member 41.

[0044] The connecting ring 221 is inserted into the mounting hole 421 by sliding movement, and the connecting ring 221 is respectively in contact with the limiting ring 4211 and the inner wall of the housing 1, so that the connecting ring 221 is stably restricted in the mounting hole 421 to prevent the connecting ring 221 from shaking in the mounting hole 421. When the rotating disk 42 rotates, the rotating disk 42 can drive the connecting ring 221 and the activated carbon plate 222 to rotate, thereby facilitating the activation of the activated carbon plate 222 to move to a specified position.

[0045] In other embodiments, the limiting ring 4211 may not be provided, and a sealing gasket may be filled between the connecting ring 221 and the inner wall of the mounting hole 421. In this case, the connecting ring 221 can contact the air delivery pipe 211 to limit the connecting ring 221.

[0046] Reference Figure 3 and Figure 5 When the rotating disk 42 drives the activated carbon plate 222 to move to the position corresponding to the air supply pipe 211, the connecting ring 221 (refer to Figure 6 ) can be connected to the air supply pipe 211 and the heat dissipation hole 11 respectively, so that when the gas flows from the air supply pipe 211 to the heat dissipation hole 11, the gas will pass through the activated carbon plate 222, so that the activated carbon plate 222 can be used to adsorb volatile organic compounds such as benzene and formaldehyde carried in the gas, thereby purifying the gas and reducing the possibility of external air pollution.

[0047] In this embodiment, a sealing ring 2112 is installed on one side of the air supply pipe 211 close to the turntable 42, and the sealing ring 2112 is filled between the air supply pipe 211 and the turntable 42, so that the gas is not easy to flow out from the gap between the air supply pipe 211 and the turntable 42, thereby facilitating the gas to stably pass through the activated carbon plate 222 and flow out from the heat dissipation hole 11. In other embodiments, the sealing ring 2112 may not be provided.

[0048] Reference Figure 6 The housing 1 is provided with a through slot 13, and the movable assembly 43 includes a connecting member 431 and a magnetic member 432. The connecting member 431 is detachably connected to the housing 1. In this embodiment, the connecting member 431 is connected to the housing 1 by screws. In other embodiments, the connecting member 431 and the housing 1 may also be connected by snaps.

[0049] The magnetic member 432 is fixedly connected to the connecting member 431. When the connecting member 431 is connected to the housing 1, the magnetic member 432 is inserted into the through slot 13. In this embodiment, the magnetic member 432 is a permanent magnet.

[0050] When the turntable 42 drives the connecting ring 221 to move to the position corresponding to the through groove 13, the magnetic component 432 can adsorb the connecting ring 221, so that when the connecting component 431 drives the magnetic component 432 to disengage from the through groove 13, the magnetic component 432 can drive the connecting ring 221 to be pulled out from the mounting hole 421, and drive the connecting ring 221 and the activated carbon plate 222 to disengage from the shell 1, thereby facilitating the replacement of the activated carbon plate 222 to reduce the possibility that the activated carbon plate 222 loses the purification effect due to adsorption saturation.

[0051] Reference Figure 5 , a controller 14 and a temperature sensor 15 are installed in the housing 1. The controller 14 is electrically connected to the temperature sensor 15 and the cooling fan 212, and the temperature sensor 15 can detect the temperature inside the housing 1 and transmit the detection data to the controller 14 for the controller 14 to identify. When the temperature inside the housing 1 exceeds a specified value, the controller 14 can control the cooling fan 212 to work, so as to dissipate heat for the electronic components inside the housing 1, thereby facilitating the display screen 3 (refer to Figure 2 ) for heat dissipation.

[0052] The implementation principle of the high-efficiency heat dissipation fan for a display screen in the embodiment of the present application is as follows: when the temperature in the housing 1 exceeds a specified value, the controller 14 controls the heat dissipation fan 212 to work, and the heat dissipation fan 212 sucks the gas in the housing 1 into the air supply pipe 211, so that the gas flows in the air supply pipe 211 and flows out from the heat dissipation hole 11 through the activated carbon plate 222, thereby facilitating the rapid dissipation of the heat generated by the electronic components inside the housing 1 to the outside air. In this process, the activated carbon plate 222 can adsorb volatile organic compounds such as benzene and formaldehyde carried in the gas to reduce the possibility of air pollution.

[0053] When the activated carbon plate 222 needs to be replaced, the driving member 41 is first started, and the driving member 41 drives the turntable 42 to rotate, and the turntable 42 drives the connecting ring 221 and the activated carbon plate 222 to move, so that the connecting ring 221 and the activated carbon plate 222 move to the position corresponding to the through groove 13, and the new connecting ring 221 and the activated carbon plate 222 move to the position corresponding to the air supply pipe 211, so as to realize the replacement of the activated carbon plate 222, so as to facilitate the use of the new activated carbon plate 222 to purify the gas. At this time, the connecting member 431 is removed from the shell 1, and the connecting member 431 drives the connecting ring 221 to detach from the shell 1 through the magnetic suction member 432, so as to facilitate the removal of the adsorption saturated activated carbon plate 222 from the shell 1.

[0054] The above are all preferred embodiments of the present application, and the protection scope of the present application is not limited thereto. Therefore, any equivalent changes made according to the structure, shape, and principle of the present application should be included in the protection scope of the present application.
