When it is necessary to dissipate heat and prevent dust from the electronic components inside the box body 1, the cooling fan 205 inside the air inlet 203 is first started, and the cooling fan 205 starts to rotate, and then the cooling fan 205 blows air from the inside of the inclined tube 201 into the inside of the box body 1, and then the air circulates inside the box body 1 After one circle, the air is discharged from the exhaust hole 4. With the continuous circulation of air, the electronic components will quickly cool down. At the same time, the flowing air can prevent the interior of the box 1 from getting wet. Then, the first dustproof net 202 and the second dustproof net 206 installed inside the exhaust hole 4 and the air inlet 203 can prevent dust from entering the interior of the box 1, thereby preventing the dust from damaging the electronic components inside the box 1.
