Therefore, they should not be construed as limitations on this utility model.

[0035] Please see Figure 1-6 This utility model provides a technical solution: a floor brush structure that facilitates the replacement of the roller brush, comprising:

[0036] Floor brush body 1;

[0037] Roller brush 2, which is assembled inside the roller brush cavity of the floor brush body 1;

[0038] The drive assembly 3 is positioned on the brush body 1, and its inner drive structure is rotatably inserted into the first connecting seat 21 at one end of the roller brush 2.

[0039] The positioning component 4 includes a second connecting seat 41, a pull plate 42 rotatably connected to the bottom of the second connecting seat 41 via a rotating shaft 43, and a locking button 44 engaged with the pull plate 42. The second connecting seat 41 is rotatably connected to the other end of the roller brush 2, and is embedded in one end of the roller brush cavity along with the pull plate 42. A locking block 421 on one side of the pull plate 42 abuts against the slot 11 in the roller brush cavity. The locking button 44 is laterally elastically slidably disposed in the sliding groove 12 of the floor brush body 1, and the sliding groove 12 extends into the roller brush cavity.

[0040] To facilitate the rotational insertion and docking of the roller brush 2 onto the drive assembly 3, the first connecting seat 21 is inserted into the positioning groove 31 of the drive structure. Its inner side is provided with an inner ratchet structure 22 and a slot 23. The inner ratchet structure 22 is fitted onto the snap-fit ​​ratchet 32 ​​in the center of the positioning groove 31, and the slot 23 is inserted into the insert block 33 in the center of the snap-fit ​​ratchet 32. During installation, the first connecting seat 21 is inserted at an angle into the positioning groove 31, and the roller brush 2 rotates radially around the drive structure, causing the positioning assembly 4 to press into the roller brush cavity. During this process, the inner ratchet structure 22 and the slot 23 rotate within the positioning groove 31 and are correspondingly inserted and fitted onto the snap-fit ​​ratchet 32 ​​and the insert block 33, achieving docking of the roller brush 2 with its drive end. The drive structure as a whole rotates and is connected to the drive assembly 3. When the motor on the drive assembly 3 starts, the drive structure drives the roller brush 2 to rotate.

[0041] The top of the slot 11 has an arc-shaped groove for the rotational avoidance of the card block 421.

[0042] The locking button 44 and the outer end of the slide groove 12 are stepped structures to limit their sliding. The slide groove 12 is an L-shaped structure, and a spring is provided between its interior and the inner side of the locking button 44.

[0043] The locking button 44 has a second hook 441 extending downward from its inner side, and the second hook 441 is laterally engaged with the first hook 422 on the inner side of the rear end of the pull plate 42.

[0044] A U-shaped guide seat 13 with its opening facing downwards is provided at one end of the roller brush cavity near the positioning component 4, and the positioning block 45 on the outer side of the second connecting seat 41 is inserted into the opening of the U-shaped guide seat 13. This design further realizes the axial and radial positioning of the driven end of the roller brush, and facilitates structural rotation guidance during installation, thereby improving assembly and disassembly efficiency.

[0045] The brush cavity extends from the top of the pull plate 42 with an ejector groove 14. A cross-shaped ejector block 46 is embedded in the ejector groove 14, and a spring is provided between the ejector groove 14 and the ejector block 46. This design is used to lock the button 44 inward. After the positioning component 4 is unlocked, the pull plate 42 is ejected, facilitating the pull out of the positioning component 4 and the brush 2. The cross-shaped ejector block 46 is designed for sliding limitation with respect to the ejector groove 14, with its central flange abutting against the inner side of the ejector groove 14.

[0046] The working principle of a floor brush structure for easy replacement of the roller brush in this embodiment includes: When the roller brush 2 is installed, the first connecting seat 21 is inserted obliquely into the positioning groove 31, and the roller brush 2 is rotated to the side. The positioning component 4 is pressed into the roller brush cavity, and the positioning block 45 is pressed into the U-shaped guide seat 13 for rotational guidance. During this period, the inner ratchet structure 22 and the slot 23 rotate and move within the positioning groove 31, and are correspondingly inserted and assembled on the snap-fit ​​ratchet 32 ​​and the insert block 33 to realize the docking of the roller brush 2 with its drive end. After the second connecting seat 41 is positioned, the locking button 44 is pressed, and the pull plate 42 is rotated toward the second connecting seat 41 so that it is also pressed into the roller brush cavity. During this period, the locking block 421 is engaged in the slot 11. The locking button 44 is released, so that it springs back and resets, and the two hooks are locked, thereby realizing the positioning of the positioning component 4. During disassembly, press the locking button 44 to unlock the hook, push out the ejector block 46 under the action of the spring, and push out the pull plate 42. Then pull the pull plate 42 downward, so that it drives the second connecting seat 41 and the roller brush 2 to rotate along the positioning groove 31, thereby disassembling the roller brush 2.

[0047] In summary, due to the adoption of the above technical solution, the floor brush structure of this embodiment, which facilitates the replacement of the roller brush, has the following advantages compared with the prior art:

[0048] The brush structure of this invention uses a first connecting seat that can be rotatably inserted into the drive structure to position the drive end of the roller brush. A positioning component, in conjunction with a locking button, positions the driven end of the roller brush. The rotatable connection between the second connecting seat on the positioning component and the pull plate facilitates pressing in and pulling out. The overall design eliminates the conventional method of locking and positioning the roller brush with bolts at the end, enabling quick assembly and disassembly of the roller brush, facilitating replacement, cleaning, and maintenance.

[0049] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
