Specifically, the impeller 3 is linked with a first transmission gear 41 through a first transmission mechanism, and the first transmission gear 41 is linked with a cam 43 through a second transmission mechanism; wherein the periphery of the cam 43 is a circular gear portion; the first transmission mechanism and the second transmission mechanism are gear transmission mechanisms; the axis of the driving gear 45 is engaged with a rotation shaft 451, and the traveling wheels 7 are engaged with both ends of the rotation shaft 451. The walking wheels 7 may be crawler wheels, and two ends of the rotating shaft 451 are respectively connected to the axle centers of the driving wheels of the crawler wheels.
The slider assembly 46 includes a first slider 461 and a second slider 462, wherein one end surface of the first slider 461 is provided with a sliding rod 4611 mounted in the cam groove 431 of the cam 43, and the other end surface of the first slider 461 is formed with a track groove 4612; the second slider 462 is provided with a rotating rod 4621 installed in the track groove 4612, and the center of the idler pulley 44 is provided with a center hole sleeved on the rotating rod 4621; the second slider 462 is rotatably fitted on the rotation shaft 451 via a connection rod 463 around the rotation shaft 451; one end of the connecting rod 463 is formed with a first sleeve hole for sleeving the rotating rod 4621, the other end of the connecting rod 463 is formed with a second sleeve hole for sleeving the rotating shaft 451, and the idle gear 44 can be ensured to be always meshed with the driving gear 45 through the connecting rod 463. As shown in fig. 2 to 4, when the cam 45 rotates, the first slider 461 reciprocates linearly in a straight line with the rotation of the cam groove 431 of the cam 43, and the second slider 462 reciprocates in an arc around the rotation shaft 451 with the linear reciprocation of the track groove 4612 of the first slider 461; the second slider 462 is reciprocated in an arc such that the idler gear 44 fitted on the second slider 462 is also reciprocated in an arc such that the idler gear 44 is periodically switched between two states of engagement with the first transmission gear and engagement with the second transmission gear.
Further, the water inlet of the water inlet pipe 1 and the water outlet of the water outlet pipe 2 face to the upper side of the shell 5 of the pool cleaner B so as to avoid the influence of the reaction force generated when the water flows from the water inlet pipe 1 to the water outlet pipe 2 on the movement of the pool cleaner B.
