[0002] A sweeping robot is an automated household appliance designed to automatically clean the floor in a home or office environment. They are usually equipped with functions such as automatic navigation, scheduled cleaning, automatic charging, and intelligent recognition. The use of sweeping robots can greatly reduce the burden of daily cleaning, especially suitable for busy modern life. With the development of technology, sweeping robots are becoming more and more intelligent and efficient.
[0003] The roller brush is a very important component of a sweeping robot. Since it constantly rubs against the ground during operation, the roller brush needs to be removed and replaced after long-term use. The installation and fixation of the roller brush requires its installation shaft to be inserted into the installation structure at both ends. When the roller brush needs to be replaced, the installation structure needs to be disassembled to take out the roller brush. After the roller brush is replaced, the installation structure needs to be reinstalled. It can be seen that the existing roller brush installation structure makes it time-consuming and laborious for users to replace the roller brush, which increases the burden of daily cleaning for users.

[0022] Reference Figure 1 and Figure 2 , showing a roller brush quick assembly and disassembly structure 10 of a sweeping robot provided in this embodiment, comprising a mounting sleeve 1, a mounting pin 2, a limit block 3, a compression spring 4, a fixing block 5 and a screw. One end of the mounting sleeve 1 is used to be fixed on the roller brush mounting structure of the sweeping robot, and the other end thereof has an opening 11. The limit block 3 and the compression spring 4 are embedded in the mounting sleeve 1, and the compression spring 4 is sandwiched between the limit block 3 and the roller brush mounting structure.
[0023] In order to prevent the limiting block 3 from being separated from the mounting sleeve 1 , the size of the opening of the mounting sleeve 1 is smaller than the size of the limiting block 3 , so as to limit the limiting block 3 to always be located in the mounting sleeve 1 .
[0024] One end of the mounting pin 2 is a connecting end, and the other end is a plug-in end. The connecting end is fixedly connected to the limit block 3, and the plug-in end is used to be plugged with the end of the roller brush.
[0025] A through hole 31 is provided in the middle area of the limit block 3, and a screw hole 21 is provided at the connecting end of the mounting pin 2. After passing through the limit block 3, the connecting end of the mounting pin 2 is fastened to the limit block 3 through the fixing block 5 and screws.
[0026] Furthermore, one end of the mounting sleeve 1 fixedly connected to the roller brush mounting structure of the sweeping robot extends a connecting portion 12 toward the outer side of the periphery, and a mounting hole 121 is provided on the connecting portion. The mounting sleeve 1 can be fixed to the roller brush mounting structure by inserting a screw into the mounting hole 121.
[0027] The shape and size of the internal cavity of the installation sleeve 1 match the shape and size of the stop block 3. Preferably, the shape of the internal cavity of the installation sleeve 1 and the shape of the stop block 3 are both cylindrical. Through the matching design of the shape and size, the stop block 3 can be limited and guided, so that the stop block 3 is smoother and more stable during the movement.
[0028] Reference Figure 3 The present embodiment further provides a sweeping robot, comprising a chassis 20, a roller brush 30 and a roller brush mounting structure 40 located at both ends of the roller brush, the roller brush mounting structure 40 being fixed on the chassis 20, and one end of the roller brush 30 being mounted on the roller brush mounting structure 40 via the above-mentioned roller brush quick assembly and disassembly structure 10.
[0029] Reference Figure 4 A square hole 301 is provided at one end of the roller brush 30 , and correspondingly, the plug-in end of the mounting pin 2 is in a square column shape, and the plug-in end of the mounting pin 2 is inserted into the square hole 301 .
[0030] After the quick assembly and disassembly structure is applied, when installing the roller brush 30, the user first docks one end of the roller brush 30 with the installation pin 2, and then pushes the roller brush 30 to the side direction (i.e., the side of the chassis 20 where the roller brush quick assembly and disassembly structure 10 is installed). At this time, the compression spring 4 is compressed to make room for the other end of the roller brush 30 to align with the roller brush installation structure 40 on the other side of the chassis 20. After the alignment is completed, the pushing force on the roller brush 30 is released, the compression spring 4 returns to its original state (extends), and pushes the roller brush 30 to dock with the roller brush installation structure 40 on the other side. The roller brush 30 is released, and the installation of the roller brush 30 is completed. After the installation is completed, the roller brush 30 is always subjected to the reverse force of the roller brush installation structures 40 on both sides, so that the roller brush 30 can be firmly installed on the chassis 20 of the sweeping robot.
[0031] Reference Figure 5The sweeping robot of this embodiment further includes a garbage collection tray 50 and two side brushes 60. The two side brushes 60 are respectively fixed on both sides of the chassis 20 and are located in front of the roller brush 30. The bristles of the two side brushes 60 overlap in the middle area between them, and the garbage collection tray 50 is located behind the roller brush 30. Through the overlapping design of the bristles of the side brushes 60, the garbage on both sides can be better moved to the middle position, and finally collected by the roller brush 30 and sent to the garbage collection tray 50 at the rear.
[0032] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions and improvements made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
