[0026] The heat dissipation module 4 is often replaced and disassembled during use, and is repaired and cleaned to maintain better heat dissipation efficiency to protect the safe operation of the device. Figure 3 - Figure 4 As shown,

[0027] The heat dissipation module 4 includes a connecting plate 9, a bracket 41 is installed on the connecting plate 9, a transmission block 44 is installed in the bracket 41, a knob 43 is installed on the transmission block 44 for controlling the movement of the transmission block 44, a resistance block 441 is provided on the transmission block 44, a fan 42 is installed on the transmission block 44, and the fan 42 is driven by a motor.

[0028] The abutment block 441 slides in the slide groove 451 along its outer wall, the transmission block 44 moves up and down in the transmission housing 45, and the locking block 46 rotates in the fixing platform 48;

[0031] Embodiment 1:

[0032] When the heat dissipation module 4 is locked, the operator aligns the lock head 461 with the limit groove notch set on the lock plate 491 and inserts it into the limit groove, then turns the knob 43 downward, after which the lock block 46 enters the cavity, and the knob 43 is continuously pressed down, driving the transmission block 44 to be pressed down, and the resistance block 441 enters the parallel groove of the slide groove 451 from the slot (not marked in the figure), and then enters the closing groove along the groove wall of the slide groove 451.
