DETAILED DESCRIPTION OF PREFERRED EMBODIMENTS

The technical solutions in the embodiments of the present disclosure will be clearly and completely described hereinafter with reference to the accompanying drawings in the embodiments of the present disclosure. Obviously, the described embodiments are only part of the embodiments of the present disclosure, rather than all embodiments. Based on the embodiments of the present disclosure, all other embodiments obtained by those of ordinary skill in the art without making creative efforts fall within the protection scope of the present disclosure.

Please refer to FIGS. 1 to 4, the present disclosure provides a technical solution: A swimming pool cleaning robot including a replaceable cleaning roller, a robot body 1 and a cleaning roller 2, wherein an accommodating portion 11 configured to accommodate the cleaning roller 2 is provided at a bottom of an advancing end of the robot body 1; a driving block 4 that drives the robot body 1 to move in a forward direction is mounted rotatably on an inner wall of one side of the accommodating portion 11; one end of the cleaning roller 2 is snap-fitted with the driving block 4, and the driving block 4 drives the cleaning roller 2 to rotate synchronously; a telescopic clamping mechanism 3 is arranged on an inner wall of another side of the accommodating portion 11, and the clamping mechanism 3 is clamped together with another end of the cleaning roller 2 away from the driving block 4.

The driving block 4 includes a driving block 4 that rotatably connected with the robot body 1. A concave groove 41 is defined on the driving block 4, and a snap-fitting block 21 is mounted fixedly on the end of the cleaning roller 2 that is snap-fitted the driving block 4, a profile of the snap-fitting block matches the concave groove 41.

The clamping mechanism 3 includes a cylindrical component 31 arranged fixedly on the robot body 1. A boss 32 is installed slidably inside the cylindrical component 31. The boss 32 extends through the robot body 1 to the accommodating portion 11, and the boss 32 is slidably connected with the robot body 1. A baffle 35 is arranged fixedly on one side of the cylindrical component 31 away from the accommodating portion 11. A spring 34 is connected between the baffle 35 and the boss 32. The boss 32 is arranged with a pin 33. The pin 33 passes through the boss 32 and the baffle 35, and the pin 33 is moveably connected with the baffle 35. The spring 34 is slidably sleeved on the pin 33. An annular block 22 is mounted on one side of the cleaning roller 2. The annular block 22 matches the boss 32 and the pin 33.

A circular hole is opened on the boss 32 to accommodate the pin 33. A bearing is sleeved fixedly on the pin 33, and the outer of the bearing is fixedly connected to the inner wall of the circular hole.

The pin 33 is fitted with a clearance of the annular block 22.

Further, as the diameter of the pin 33 fits the clearance of the annular block 22, on the premise of the snap-fitting block 21 inserting into the groove 41, when the pin 33 is inserted into the annular block 22, the cleaning roller 2 will not shake when rotating along the axis.

An elastic pad is fixedly installed on an inner wall of the groove 41.

Further, adding the elastic pad can increase the tightness of connection between the snap-fitting block 21 and the inner wall of the groove 41.

Operating principle: When installing the cleaning roller 2 on the accommodating portion 11 of the robot body 1, the annular block 22 aims to the pin 33 and the pin 33 can be inserted into the annular block 22 by holding the cleaning roller 2; then the boss 32 is squeezed by the circular block 22, so that the boss 32 is contracted into the cylindrical component 31 and compress the spring 34; then adjusting the angle of the cleaning roller 2, making the cleaning roller 2 being arranged at a same axis with the driving block 4; then holding the cleaning roller 2 to insert the snap-fitting block 21 on one side of the cleaning roller 2 into the groove 41. At this time, the compressed spring 34 will push the boss 32 closer to the cleaning roller 2 and tightly abut to the annular 22. At this time, both sides of the cleaning roller 2 are simultaneously restricted and will not fall off from the accommodating portion 11. Subsequently, during the process of advancing the robot body 1, the mechanism that drives the robot body 1 to move forward will drive the groove to rotate synchronously, and the rotating groove 41 will drive the cleaning roller 2 to rotate to clean the swimming pool;

When detaching the cleaning roller 2 from the accommodating portion 11 of the robot body 1, it only needs to grip the cleaning roller 2 to move towards one side of the boss 32. By pressing the boss 32 into the cylindrical component 31, the cleaning roller 2 will move towards the boss 32 and make the snap-fitting block 21 at the other end of the cleaning roller 2 separated from the groove 41. Subsequently, the snap-fitting block 21 and the driving block 4 are staggered by rotation, and then the cleaning roller 2 is pulled to disengage the pin 33 from the annular block 22 so as to take out the cleaning roller 2 from the accommodating portion 11.

The above descriptions are only preferred embodiments of the present disclosure and are not intended to limit the present disclosure. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present disclosure shall be included within the protection scope of this disclosure.
