[0055] Automatic pool cleaning machine, including the body of the automatic pool cleaning machine mentioned above.

[0056] Working principle: During use, the rotation of the motor spindle 15 drives the drive wheel 201 to rotate. The rotation of the drive wheel 201 drives the end wheel 203 and the support wheel 204 to rotate via the transmission belt 202, which in turn drives the two sets of roller brushes 4 to rotate and clean the pool. During the operation of the device, the transmission component 2 is set between the main shell 1 and the protective cover 3, so that the outer end face of the drive wheel 201 and the outer end face of the support wheel 204 are both abutted against the inner cover 302. At the same time, through the cooperation of the main abutment plate 9 and the main cylinder 10, the outer ring of the main outer bearing 13 is fixedly connected to the main wheel body 21, and the outer end face of the inner ring of the main outer bearing 13 abuts against the main abutment plate 9. The main cylinder 10 is fixedly connected to the main outer bearing 13. The inner ring is fixed inside, thus limiting the axial and radial positions of the drive wheel 201. The inner sleeve 22 is fixedly connected to the inner ring of the support wheel 204, and the secondary cylinder 11 is fixedly connected to the inside of the inner sleeve 22. The inner sleeve 22 has an inner protrusion 23 on the side facing the secondary cylinder 11, and the secondary cylinder 11 has an inner partition 24 on the side facing the inner sleeve 22. The inner partition 24 abuts against the inner protrusion 23, thereby limiting the axial and radial positions of the support wheel 204. This minimizes the wobbling of the drive wheel 201 and the support wheel 204 during rotation and reduces the transmission resistance of the automatic pool cleaner, thus improving the cleaning efficiency of the automatic pool cleaner.

[0057] The above are all preferred embodiments of this utility model, and are not intended to limit the scope of protection of this utility model. Therefore, all equivalent changes made to the structure, shape and principle of this utility model should be covered within the scope of protection of this utility model.
