Central air-conditioner pipeline type ventilation system cleaning robot

The present invention discloses a central air-conditioning pipeline type ventilation system cleaning robot. It includes a traveling mechanism and a cleaning mechanism. Said traveling mechanism uses anadsorption electromagnetic iron as main component so as to make the whole machine be adsorbed on the side wall of pipeline and traveled instead of traditional four-wheel drive car mode, and the bidirectional 45 deg movements implemented by using two pairs of crank-link mechanisms to drive slide block along the guideway can synthesize the movement along the horizontal or vertical direction, so that it can be traveled along the transverse pipe and vertical pipe and can elude obstruction.
