Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0028] Please see Figures 1-8 One embodiment provided by the present invention:

[0029] A convenient-to-maintain walk-behind floor scrubber for shopping malls includes a scrubber body 1. A liquid replenishment tank 11 is located on the top of the scrubber body 1. Four sets of casters 12 are installed on the bottom of the scrubber body 1. A control panel 13 is fixedly connected to the top of the scrubber body 1 away from the liquid replenishment tank 11. An adjustment groove 14 is located inside the end of the scrubber body 1 closest to the control panel 13. A circular groove 15 is located inside the end of the scrubber body 1 closest to the control panel 13. A liquid replenishment pipe 2 is fixedly connected inside the liquid replenishment tank 11. A pipe cap 21 is rotatably connected to the top of the liquid replenishment pipe 2. A water tank 22 is fixedly connected to the bottom of the liquid replenishment pipe 2. A water pump 23 is fixedly connected to one side of the water tank 22. A connecting pipe 24 is fixedly connected to the output end of the water pump 23. The bottom of the connecting pipe 24 is fixedly... The floor scrubber body 1 is fixedly connected to multiple spray heads 25. A brush motor 3 is fixedly connected to the bottom of the brush motor 3. A mounting plate 31 is fixedly connected to the bottom of the mounting plate 31. A sweeping disc 32 is mounted on the bottom of the mounting plate 31. Two sets of plug-in blocks 33 are symmetrically fixedly connected to the top of the sweeping disc 32. A first sliding groove 34 is formed on the top of the plug-in block 33, and a second sliding groove 35 is formed at the bottom of the first sliding groove 34. Hand-tightening bolts 36 are rotatably connected to both sides of the mounting plate 31. Mounting structures 4 are provided on both sides of the mounting plate 31. The mounting structure 4 includes a mounting groove 41 and a third sliding groove 42. A fixing rod 43 is fixedly connected inside the mounting groove 41 and the third sliding groove 42. A slider 44 is slidably connected to the surface of the fixing rod 43. A plug rod 45 is fixedly connected to one side of the slider 44. A spring 47 is fixedly connected to the side of the slider 44, and a pull rod 46 is fixedly connected to the top of the slider 44. An adjustment structure 5 is provided at one end of the floor scrubber body 1 near the control panel 13. The adjustment structure 5 includes an adjustment column 51, a limit block 52 fixedly connected to the bottom of the adjustment column 51, a handle 53 fixedly connected to the top of the adjustment column 51, and multiple sets of slots 54 formed on the surface of the adjustment column 51. A crossbar 55 is slidably connected to the surface of the floor scrubber body 1, and connecting rods 56 are fixedly connected to both sides of the crossbar 55. A limit block 57 is fixedly connected to the surface of the connecting rod 56, a spring 58 is sleeved on the surface of the connecting rod 56, and a locking block 59 is fixedly connected to one end of the connecting rod 56. An installation disc 31, a cleaning disc 32, and an installation structure 4 are provided. The cleaning disc 32 needs to be adjusted... During disassembly and replacement, unscrew the hand-tightening bolt 36 from the threaded groove 1, pull the pull rod 46 to move the slider 44 on the fixed rod 43, causing the insertion rod 45 to move from the sliding groove 2 35 to the sliding groove 3 42, compressing the spring 47. Since the fixed rod 43 is connected to the sliding groove 1 34, the insertion block 33 can slide on the fixed rod 43 through the sliding groove 1 34, and the insertion rod 45 is no longer engaged with the sliding groove 2 35. The insertion block 33 can then be slid out of the mounting slot 41, allowing the sweeping disc 32 to be cleaned and replaced. Installation is performed by reversing the operation. No other tools are needed for installation and disassembly, facilitating the cleaning and replacement of the sweeping disc 32 and making maintenance more convenient. An adjustment structure 5 is provided; to adjust the height of the handle 53, pull the handle 53 upwards.A set of slots 54 on the adjusting column 51 engages with the inclined surface of the locking block 59. As the adjusting column 51 moves upward, it pushes the locking block 59 into the circular groove 15. The limiting block 57 compresses the spring 58, causing the surface of the locking block 59 to abut against the surface of the adjusting column 51. When the locking block 59 aligns with another set of slots 54, the spring 58 pushes the locking block 59 into the other set of slots 54. The locking block 59 and the other set of slots 54 engage, preventing the adjusting column 51 from moving downward. Repeating this operation adjusts the handle 53 to a suitable height. The height of the handle 53 can be adjusted according to the user's habits, offering good adaptability.

[0030] Furthermore, the water pump 23 and the brush motor 3 are both electrically connected to the control panel 13, which is electrically connected to an external power source. The water pump 23 and the brush motor 3 are controlled through the control panel 13 and powered by the external power source.

[0031] Furthermore, the connecting pipe 24 is semi-circular, and multiple sets of nozzles 25 are equidistantly arranged on the circumference of the surface of the connecting pipe 24. The multiple sets of connecting pipes 24 are inclined to increase the spraying range. The cleaning liquid in the water tank 22 is pumped out by the water pump 23 and sprayed onto the ground from the nozzles 25, thereby increasing the cleaning effect of the sweeping disc 32.

[0032] Furthermore, slider 44 and pull rod 46 are slidably connected in slide groove 42, and insert rod 45 is inserted into mounting groove 41 through one inner wall of slide groove 42. Circular groove 2 is opened on the surface of slider 44 and insert rod 45. Sliding slider 44 and insert rod 45 are slidably connected to the surface of fixing rod 43 through circular groove 2. The two ends of fixing rod 43 are fixedly connected to the inner wall of slide groove 42 and the inner wall of mounting groove 41, respectively. The movement of slider 44 and insert rod 45 is limited by fixing rod 43, which increases the stability of slider 44 and insert rod 45 when moving and prevents deviation.

[0033] Furthermore, spring 47 is sleeved on the surface of fixed rod 43. The two ends of spring 47 are fixedly connected to the inner wall of slide groove 42 and the surface of slider 44, respectively. When spring 47 deforms, it will not interfere with the surface of fixed rod 43. Without external force, slider 44 is reset by spring 47.

[0034] Furthermore, the plug-in block 33 is inserted into the mounting groove 41. The cross-section of the fixing rod 43 is the inscribed circle of the cross-section of the first slide groove 34. The plug rod 45 is inserted into the second slide groove 35. The cross-section of the second slide groove 35 is larger than that of the first slide groove 34. Since the fixing rod 43 is inscribed in the first slide groove 34, the plug-in block 33 can slide on the fixing rod 43 through the first slide groove 34. When the plug rod 45 is inserted into the second slide groove 35, it engages with the second slide groove 35, fixing the plug-in block 33 in the mounting groove 41.

[0035] Furthermore, both the mounting plate 31 and the plug-in block 33 have threaded grooves on their surfaces. The hand-tightening bolt 36 is rotatably connected in the threaded groove. The plug-in block 33 is further fixed by the cooperation between the hand-tightening bolt 36 and the threaded groove, ensuring the stability of the installation between the mounting plate 31 and the cleaning plate 32.

[0036] Furthermore, the radius of the limiting block 52 is larger than the radius of the adjusting column 51. The limiting block 52 is slidably connected in the adjusting groove 14. The adjusting groove 14 and the circular groove 15 are connected. The connecting rod 56 passes through one inner wall of the circular groove 15 and is fixedly connected to the locking block 59. The cross-section of the connecting rod 56 is larger than the cross-section of the locking block 59. The movement of the adjusting column 51 is limited by the limiting block 52 to prevent the adjusting column 51 from sliding out of the floor scrubber body 1. The locking block 59 can be driven to slide in the adjusting groove 14 and the circular groove 15 by the connecting rod 56.

[0037] Furthermore, the second limiting block 57 is slidably connected within the first circular groove 15. The radius of the second limiting block 57 is larger than the radius of the connecting rod 56. The two ends of the second spring 58 are fixedly connected to the surface of the second limiting block 57 and the inner wall of one side of the first circular groove 15, respectively. The second limiting block 57 limits the connecting rod 56 to prevent it from sliding out of the first circular groove 15. When there is no external force, the second spring 58 resets the second limiting block 57. When the second spring 58 deforms, it will not interfere with the connecting rod 56.

[0038] Furthermore, the cross-section of the locking block 59 is triangular, with the inclined surface of the locking block 59 facing downwards. The locking block 59 matches the locking slot 54. When the locking block 59 is inserted into the locking slot 54, because the inclined surface of the locking block 59 faces downwards, the top of the locking block 59 will engage with the top of the locking slot 54, preventing the adjusting column 51 from moving downwards. When the adjusting column 51 moves upwards, the bottom of the locking slot 54 contacts the inclined surface of the locking block 59, pushing the locking block 59 into the circular groove 15, thereby adjusting the height of the adjusting column 51.

[0039] Working principle: When the sweeping disc 32 needs to be disassembled and replaced, the hand-tightening bolt 36 is turned out of the threaded groove 1 and pulled. The pull rod 1 46 is pulled to make the slider 44 slide on the fixed rod 43, so that the insertion rod 45 moves from the sliding groove 2 35 to the sliding groove 3 42, compressing the spring 1 47. Since the fixed rod 43 is connected to the sliding groove 1 34, the insertion block 33 can slide on the fixed rod 43 through the sliding groove 1 34, and the insertion rod 45 is no longer engaged with the sliding groove 2 35. Then the insertion block 33 can be slid out of the mounting groove 41, and the sweeping disc 32 can be cleaned and replaced. The handle needs to be adjusted. When the height is 53, pull up the handle 53. A set of slots 54 on the adjusting column 51 engages with the inclined surface of the locking block 59. The adjusting column 51 moves upward, pushing the locking block 59 into the circular groove 15. The limiting block 2 57 compresses the spring 2 58, causing the surface of the locking block 59 to abut against the surface of the adjusting column 51. When the locking block 59 is aligned with another set of slots 54, the spring 2 58 pushes the locking block 59 into the other set of slots 54. The locking block 59 and the other set of slots 54 engage with each other, preventing the adjusting column 51 from moving downward. Repeat the above operation to adjust the handle 53 to a suitable height.

[0040] It will be apparent to those skilled in the art that the present invention is not limited to the details of the exemplary embodiments described above, and that the invention can be implemented in other specific forms without departing from its spirit or essential characteristics. Therefore, the embodiments should be considered in all respects as exemplary and non-limiting, and the scope of the invention is defined by the appended claims rather than the foregoing description. Thus, all variations falling within the meaning and scope of equivalents of the claims are intended to be included within the present invention. No reference numerals in the claims should be construed as limiting the scope of the claims.
