Specific embodiment
The preferred embodiment of the utility model is illustrated below in conjunction with attached drawing, it should be understood that described herein excellent
Embodiment is selected to be only used for describing and explaining the present invention, is not used to limit the utility model.
Embodiment：As shown in Figs 1-4, including control cabinet 14,14 front end of control cabinet is provided with operation panel 1, the behaviour
Make to be provided with loudspeaker 4 on plate 1,4 lower section of loudspeaker is provided with display screen 3, and 3 lower section of display screen is provided with keypad
2,2 side of keypad is provided with power switch 8, and miniature motor 6, the miniature motor 6 are provided on the control cabinet 14
One end is connected with radiator fan 7, and 14 surface of control cabinet is set inside the control cabinet 14 covered with PVC electrostatic protections film 12
Power supply 11 is equipped with, 11 side of power supply is provided with control host 13, and 14 outside of control cabinet is provided with copper mesh 5, the copper
5 side hollow out of net, hollow out shape are circle, and the radiator fan 7 is located just on round openwork hole, 5 back of copper mesh
Hollow out, hollow out shape are rectangle, and 5 four jiaos of the copper mesh is provided with screw 9.
It is simple in structure in order to make this kind of microcomputer protecting device, it is easy to use, it is the display screen 3, the loudspeaker 4, described
Operation panel 1 passes through electric connection, the miniature motor 6, the power switch 8, the control host with the control host 13
13 with the power supply 11 by being electrically connected, the copper mesh 5 is fixedly connected with the operation panel 1 by the screw 9, described scattered
Hot-air fan 7 is with the miniature motor 6 by axis connection, and the control cabinet 14 is fully wrapped around by the copper mesh 5, and the copper mesh 5 compares
14 volume of control cabinet is big, and is not contacted with the control cabinet 14.
