Needless to say, the content protected by the utility model does not involve improvements to the internal structure and method.

[0041] Working principle: When the display screen 120 needs to be flipped over for inspection, first remove the cover plate 113, and then push the sliding plate 112 to the right so that the sliding plate 112 is away from the top of the lifting block 115, and then lift the lifting block 115 upward to rotate the rear end of the display screen 120 upward, and then pull the display screen 120 upward so that the two support rods 141 rotate and extend between the rotating connecting member 142 and the supporting member 140, so that the display screen 120 is moved out from the inside of the inclined member 110. At this time, the rear end of the display screen 120 can be flipped up, and the support rod 141 extends to support the display screen 120. At the same time, the rotating connecting member 142 cooperates with the two support rods 141 to rotate and also support the display screen 120, so that the display screen 120 can be easily separated from the top of the inclined member 110 and flipped over, so that the electrical components behind the display screen 120 can be conveniently inspected and maintained, which solves the problem that the common display screen 120 is fixed to the inclined member 110 with multiple bolts and is inconvenient to separate and flip. When the internal electrical components of the all-in-one machine are heated up during use, the deformation tube 230 is bent in advance so that the air inlet end of the deformation tube 230 fits inside the gap between the electrical components. The vacuum pump 240 is turned on by controlling the switch 203. When the vacuum pump 240 is running, the hot air in the gap between the electrical components is sucked into the internal tube 220 through the deformation tube 230. When the hot air then passes through the connecting tube 210, part of the heat can be dissipated outward through the heat dissipation fins 211. The hot air then passes through the vacuum pump 240 and is discharged through the exhaust port 202. Thus, the vacuum pump 240 can be used to extract the hot air in the gaps between the electrical components at multiple points inside the housing 100, thereby promoting the heat dissipation of the internal electrical components of the teaching multimedia all-in-one machine and facilitating the stable operation of the multimedia all-in-one machine.
