Double-filtering module, filtering device and sweeper

The invention provides a double-filtering module which is characterized in that the double-filtering module comprises two filtering modules, a first interval is arranged between the two filtering modules, and the two filtering modules are arranged in parallel; the fluid assembly and the filtering module are coaxially arranged; according to the device, the suction force of the double filtering modules is greatly improved through the double-channel dust collection and filtering system, so that the double filtering modules efficiently absorb and filter raised dust, clean air is discharged, secondary pollution is avoided, the suction force can be better by absorbing and filtering the raised dust through the two filtering modules, the filtering effect is multiplied, and the dust collection efficiency is improved. The use in a heavy dust environment is met. 本发明提供了一种双过滤模组，其特征在于，包括两个过滤模组，所述两个过滤模组之间设置有第一间距，且所述两个过滤模组平行设置；以及流体组件，所述流体组件与所述过滤模组同轴心线设置；该装置通过双通道吸尘过滤系统大大的提高了双过滤模组的吸力，使得双过滤模组对扬尘进行高效吸收、过滤，已排出干净的空气，避免二次污染的产生，且通过两
