Description

Technical Field

[0001] This utility model relates to the field of floor scrubber technology, specifically a cleaning device. Background Technology

[0002] With the increasing demand for modern home cleaning and the diversification of cleaning scenarios, floor scrubbers are widely used in homes, shopping malls and other places due to their efficient cleaning capabilities.

[0003] When dealing with complex environments such as carpets and tile grout, traditional floor scrubbers rely solely on the direct cleaning of the rollers. This is insufficient for cleaning dirt embedded in carpet fibers or dried stains, and the rollers are prone to getting tangled with hair, fibers, and other debris. When cleaning complex environments, workers usually need to purchase separate pre-cleaning components or adjust the roller speed to enhance cleaning. However, separate components increase the size and cost of the equipment and cannot be flexibly adjusted. Simply increasing the speed can lead to increased energy consumption and noise. In terms of preventing tangling, workers usually need to rely on the fixed combs or removable baffles installed on the floor scrubber. However, fixed combs and removable baffles have drawbacks such as fixed cleaning angles and limited cleaning range, making them less than satisfactory when used in complex environments.

Detailed Implementation

[0021] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0022] Please see Figures 1-6 As shown, a cleaning device includes a brush head assembly 1 and a transparent window cover 2 installed on the top of the brush head assembly 1. A spring-locked multi-degree-of-freedom comb assembly 3 is installed on the top of the transparent window cover 2. A connecting groove 21 is opened on the top of the transparent window cover 2, and the outer wall of the connecting groove 21 contacts the connecting plate 31. Rotating grooves 22 are opened on both sides of the top of the transparent window cover 2, and a rotating seat 343 contacts the outer wall of the rotating groove 22. A buckle 23 for easy installation and disassembly is fixedly connected to the bottom of the transparent window cover 2. The transparent window cover 2 allows for intuitive observation of the usage status of the floor scrubber roller and the adjustment degree of the comb assembly 3, realizing visualized maintenance. The bottom buckle 23 design simplifies the disassembly and assembly process and improves maintenance efficiency. The top connecting groove 21 cooperates with the connecting plate 31, and the rotating groove 22 is adapted to the threaded rotating assembly 34 to ensure convenient assembly of each component and enhance the overall structural stability.

[0023] It should be noted that the connecting plate 31 is fixed by using the locking heads 331 and the limiting blocks 341 at both ends in conjunction with the spring locking assembly 33 and the rotating seat 343. This is equivalent to directly installing the connecting plate 31 on the relevant components. Therefore, the connecting plate 31 is only placed inside the connecting groove 21 and only contacts the transparent window cover 2 when it does not need to rotate. During use, the transparent window cover 2 does not need to provide support. The rotating seat 343 is connected to the transparent window cover 2 by connecting rods on both sides. One side is connected by a threaded shaft 344 that adjusts the overall angle of the rotating seat 343, and the other side is directly connected by a connecting rod. Because the connecting plate 31 is installed between the two rotating seats 343 by the limiting groove 342, the adjusting threaded shaft 344 can synchronously drive the two rotating seats 343 to rotate. However, the rotating seat 343 must be placed inside the rotating groove 22 and supported by the transparent window cover 2.

[0024] A connecting plate 31 is installed on the top of the comb assembly 3. A threaded lifting assembly 32 is installed inside the connecting plate 31. Spring locking assemblies 33 are installed at both ends of the top of the connecting plate 31. A threaded rotating assembly 34 is installed on one side of each of the two spring locking assemblies 33. The spring locking assemblies 33 at both ends of the top of the connecting plate 31 provide a stable locking base for the adjustment of the comb assembly 3. The cooperation between the spring locking assemblies 33 and the connecting plate 31 ensures that the comb assembly 3 will not loosen due to external force during the cleaning process, maintaining the stability of the cleaning work. At the same time, the comb assembly 3 can be disassembled separately for easy cleaning of the comb 325. The threaded rotating assembly 34 installed on one side works in conjunction with the connecting plate 31. Through the threaded connection between the threaded shaft 344 and the transparent window cover 2 and the rotation of the rotating seat 343, the comb assembly 3 can be adjusted at multiple angles, effectively expanding the cleaning range. The threaded lifting assembly 32, the threaded rod 321 and the connecting plate 31 are threadedly engaged. With the guiding action of the slide rod 323, the height of the comb 325 can be easily adjusted to adapt to different ground conditions and cleaning needs.

[0025] The threaded lifting assembly 32 includes a threaded rod 321. One end of the threaded rod 321 passes through the connecting plate 31 from top to bottom and is threadedly connected to the inner wall of the connecting plate 31. The other end of the threaded rod 321 is rotatably connected to the top of the fixed plate 322 via a bearing. Slide rods 323 are fixedly connected to both sides of the top of the fixed plate 322. One end of the slide rod 323 passes through the connecting plate 31 from top to bottom and is slidably connected to the inner wall of the connecting plate 31. A baffle 324 is fixedly connected to one side of the fixed plate 322, and a toothed comb 325 is fixedly connected to the bottom of the fixed plate 322. The threaded rod 321 is threadedly engaged with the connecting plate 31, and combined with the guide of the slide rod 323, the toothed comb 325 can be easily adjusted to adapt to different cleaning scenarios. The combination of the fixed plate 322, the baffle 324, and the toothed comb 325 ensures a stable adjustment process and improves the cleaning effect.

[0026] The spring locking assembly 33 includes a locking head 331. The top of the rectangular end of the locking head 331 is fixedly connected to the bottom of the connecting plate 31. The cylindrical end of the locking head 331 is engaged with the outer walls of the first locking claw 332 and the second locking claw 333, respectively. A spring 334 is fixedly connected to one side of the first locking claw 332 and the second locking claw 333, respectively. The other end of the spring 334 is fixedly connected to the top of the support plate 335. Two bases 336 are fixedly connected to both sides of the top of the support plate 335. The two bases 336 rotate between each other. A locking rod 337 is dynamically connected, with both ends of the locking rod 337 passing through one end of the first locking claw 332 and the second locking claw 333, respectively. The outer wall of the locking rod 337 is slidably connected to the inner wall of the first locking claw 332 and the second locking claw 333, respectively. The locking head 331 engages with the first locking claw 332 and the second locking claw 333, and is elastically reset with the spring 334 to achieve quick locking and unlocking. The locking rod 337 cooperates with the base 336 and the support plate 335 to ensure a stable locking state and prevent the parts from loosening during cleaning.

[0027] The threaded rotating assembly 34 includes a limiting block 341, which is fixedly connected to one side of the connecting plate 31. The limiting block 341 is slidably connected to the outer wall of the limiting groove 342, which is opened inside the rotating seat 343. One side of one of the rotating seats 343 is fixedly connected to a threaded shaft 344, one end of which passes through one side of the transparent window cover 2 and is threadedly connected to the inner wall of the transparent window cover 2. The other rotating seat 343 is rotatably connected to the outer wall of the transparent window cover 2 via a connecting rod. The limiting block 341 cooperates with the limiting groove 342 to constrain the movement trajectory of the rotating seat 343 and ensure that the rotation adjustment is controllable. The threaded shaft 344 is threadedly connected to the transparent window cover 2 and, in conjunction with the connecting rod rotation design, enables flexible multi-angle adjustment and expands the cleaning coverage area.

[0028] Working principle: Before using the floor scrubber, the operator first checks whether the transparent window cover 2 is fastened to the brush head assembly 1 by the buckle 23. Then, the operator checks whether the locking heads 331 at both ends of the connecting plate 31 in the comb assembly 3 are engaged with the first locking claw 332 and the second locking claw 333, and whether the limiting blocks 341 at both ends of the connecting plate 31 are embedded in the limiting grooves 342 inside the rotating seat 343. After checking, the operator should adjust the height and angle of the comb assembly 3 according to the environment to be cleaned. First, the operator rotates the threaded rod 321, which, combined with the guide of the sliding rod 323, moves the fixed plate 322 downward. Simultaneously, the baffle 324 on the side of the fixed plate 322 and the bottom comb 325 move downward. After adjusting the height... Afterwards, the staff rotates the threaded shaft 344, which drives the rotating seat 343 on the connected side to rotate. The rotation of the rotating seat 343 on one side drives the connecting plate 31 to rotate, and the rotation of the connecting plate 31 drives the rotating seat 343 on the other side to rotate, thereby adjusting the angle of the comb assembly 3. After the height and angle are adjusted, the staff can use the floor scrubber to clean. After cleaning, the staff resets the comb assembly 3 according to the previous operation, then holds one side of the transparent window cover 2 and pulls the connecting plate 31 to remove the locking head 331 from the engaged state of the first locking claw 332 and the second locking claw 333. The entire comb assembly 3 is removed, and the baffle 324 and the comb 325 are cleaned. After cleaning, it is reinstalled.
