Detailed Description
The present invention is further illustrated by the following examples, but is not limited to the details of the description.
As shown in fig. 1 and 2, in a first embodiment of the present invention, a rolling brush assembly is disclosed, which includes a rolling brush 10, a limiting member 30 and an operating portion 40, wherein the limiting member 30 is movably disposed on the rolling brush 10, and the rolling brush 10 is assembled or disassembled through the limiting member 30; the operation portion 40 is disposed on the limiting member 30, and the operation portion 40 is used for driving the limiting member 30 to move under the action of external force. When the rolling brush 10 is disassembled, the operating part 40 can be shifted by a finger, so that the operating part 40 drives the limiting part 30 to move; in assembling, after the roll brush assembly is mounted to the assembling position, the reverse movement of the operating part 40 fixes the roll brush 10, thereby achieving the mounting and dismounting of the roll brush 10.
According to the rolling brush assembly, the limiting piece 30 is movably arranged on the rolling brush 10, the rolling brush 10 can be conveniently taken down while the limiting piece 30 is moved, the limiting piece 30 can be conveniently moved to the fixed position after being assembled during assembly, and the rolling brush assembly can be operated by one hand during assembly and disassembly, so that the operation steps are greatly simplified, the assembly and disassembly efficiency is improved, and the user experience is optimized.
It should be noted that the limiting member 30 has a first position and a second position; in the first position of the limiting member 30, the limiting member 30 is in limiting fit with a preset structure; in the second position of the limiting member 30, the limiting member 30 is separated from the predetermined structure; the stopper 30 is switched between the first position and the second position by moving.
When the rolling brush 10 is dismounted, the operation part 40 is moved by hand, the limiting part 30 is electrically driven to the second position through the operation part 40, at the moment, the limiting part 30 is separated from the limiting fit with the preset structure, and meanwhile, the rolling brush 10 is continuously forced to move to the position far away from the preset structure, so that the rolling brush 10 can be taken out; when the round brush 10 is installed, after the round brush 10 is placed into the device position, the limiting part 30 can move to the first position under the action of external force, the limiting part 30 is in limiting fit with a preset structure at the moment, the movement of the round brush 10 is limited, and the round brush 10 cannot move, namely, the round brush 10 is fixed on the preset structure through the limiting part 30, the whole installation process needs to be always located on the round brush 10, and does not need to move to other positions, and other operations are not needed, therefore, the operation steps are simpler, and the user experience is good.
In this embodiment, the limiting member 30 has a first end and a second end, the first end of the limiting member 30 is rotatably connected to the rolling brush 10, the operating portion 40 is located at the second end of the limiting member 30, and the limiting member 30 is switched between the first position and the second position by rotating. The limiting part 30 is rotatably arranged on the rolling brush 10, so that the limiting part 30 can be controlled to swing through the stirring operation part 40, and the limiting fit and the separation from the limiting fit of a preset structure are realized, and the operation process is simpler and more convenient.
Further, a limiting protrusion 31 matched with the preset structure is arranged on the limiting member 30. The preset structure is provided with a limit groove 21 matched with the limit bulge 31; when the limiting member 30 is at the first position, the limiting protrusion 31 is located in the limiting groove 21 and is in limiting fit with the limiting groove 21, so that the rolling brush 10 is separated from the preset structure; when the limiting part 30 is located at the second position, the limiting protrusion 31 is disengaged from the limiting groove 21, the limiting part 30 does not limit the rolling brush 10, at this time, the operation part 40 needs to be continuously moved in the direction away from the preset structure, the limiting part 30 can be driven to move through the operation part 40, the limiting part 30 drives the whole rolling brush 10 to be disengaged from the preset structure, and therefore the rolling brush 10 is detached, and the operation process is simple and convenient.
The limiting protrusion 31 is provided with a guide surface 311 for guiding the assembling direction during assembling.
