[0020] In summary, the utility model has at least the following advantages:

[0021] 1. By setting a fan, a dust collecting device and a cleaning device, when dust needs to be collected, the fan is started, and the air inlet of the fan and the air outlet of the dust collecting device are connected through a pipeline. The fan draws out the air in the shell and forms a negative pressure state, so that the dust enters the shell through the air inlet, and the air with dust is filtered by the filter element, and then the filtered air is discharged through the fan. When the filter element is full of dust, the air pipe switch is opened and the cleaning device is operated to blow off the dust on the filter element, thereby improving the dust collection efficiency of the dust collecting device, reducing the dust accumulation of the machine equipment, thereby reducing the failure rate of the equipment and extending the service life of the equipment;
