Abstract:
A pool cleaning robot with a track lap structure (214) includes a cleaning body (1) and a drive mechanism (2). The drive mechanism (2) includes: a wheel (21) rotatably arranged on the cleaning body (1), the wheel (21) comprising a track lap structure (214) and a first engaging structure (211) which are sequentially arranged in an axial direction of the wheel (21) so as to form a limiting structure (212) on the wheel (21) or between the wheel (21) and the cleaning body (1); and a track (22) provided on the outside of the wheel (21), at least a part of the track (22) being engaged with the first engaging structure (211), so that the track (22) is driven by the wheel (21) to move, where an inner surface of the track (22) is provided with an anti-detachment structure, and the anti-detachment structure is lapped on the track lap structure (214). The anti-detachment structure provided on the inner surface of the track (22) is cooperated with the limiting structure (212) on the wheel (21), so that the position of the track (22) is fixed and the problem of loose track (22) is avoided.
