However, after using the floor washing machines, mops or washing-mops, most products need to disassemble and clean the parts. For example, the cleaning roller brush needs to be cleaned. Common cleaning methods for the cleaning roller brush include hand washing or self-cleaning.

[0003] Hand washing is inefficient, labor-intensive, and provides a poor user experience. Self-cleaning methods often involve placing the brush in water and rotating it, but stains, especially oil and dye stains, are difficult to remove, resulting in poor self-cleaning performance. The brush may need to be removed and washed manually.

[0004] Accordingly, this field requires a new technical solution to solve the above problems. Summary of the Invention

[0005] The present invention aims to solve the above technical problems, that is, to solve the problem that oil stains or dyes on the existing roller brush are difficult to wash off, resulting in poor self-cleaning effect.

[0040] like Figure 1-6As shown, in order to solve the problem that oil stains or dyes are difficult to wash off, resulting in poor self-cleaning effect, the present invention provides a base for a floor cleaning device, including a main body 1, a pressure plate 2 and a liquid discharge device (not shown in the figure); the upper surface of the main body 1 is provided with a placement groove, and the placement groove is provided with a cleaning groove 11, and the cleaning groove 11 allows the roller brush of the floor cleaning device to be placed therein; the liquid discharge device is connected to the main body 1, and the pressure plate 2 is provided on one side of the main body 1. The pressure plate 2 is connected to one end of the liquid discharge device, and the pressure plate 2 is configured to drive one end of the liquid discharge device to rotate when it is pressed down, so that the liquid discharge device sprays cleaning liquid toward the roller brush so that the cleaning liquid adheres to the roller brush. In this way, when the pressure plate 2 is pressed down, it drives one end of the liquid discharge device to rotate, and the liquid discharge device sprays cleaning liquid toward the roller brush, so that the roller brush is cleaned under the action of the cleaning liquid, and the cleaning effect of the roller brush is better. Even if there is dirt that is difficult to wash off, it can be effectively removed under the action of the cleaning liquid, and the cleaning speed is faster.

[0041] See attached Figure 2 In a preferred embodiment, the liquid discharge device includes a liquid storage tank 3, a spray assembly 5 and a transmission assembly 4. The liquid storage tank 3 is connected to the main body 1, and the liquid storage tank 3 is configured to store cleaning liquid. The spray assembly 5 is connected to the liquid storage tank 3, and the spray assembly 5 is configured to spray the liquid in the liquid storage tank 3; the transmission assembly 4 is connected to the main body 1, one end of the transmission assembly 4 is connected to the pressure plate 2, and the other end is connected to the spray assembly 5. The transmission assembly 4 is configured to extend when the pressure plate 2 is pressed down and squeeze the spray assembly 5.

[0042] In a preferred embodiment, the liquid storage tank 3 is square in shape, and the upper end of the liquid storage tank 3 is connected to the lower side of the main body 1. A liquid injection port (not shown in the figure) is opened on the upper side of the liquid storage tank 3 on the main body 1, and the liquid injection port is connected to the liquid storage tank 3. Although the liquid injection port is not shown in the drawings of this application, the location of the liquid injection port is not limited, and it can be placed in the placement groove or on the side of the main body.

[0043] It should be noted that the shape of the liquid storage bin 3 can be selected according to the specific application scenario, and can be a strip or a cylinder, as long as a liquid storage cavity is formed in the liquid storage bin 3.

[0044] The following is a detailed description of possible implementations of the transmission assembly 4 .

[0045] See attached Figure 2-6In a preferred embodiment, the transmission assembly 4 includes a rotating rod 41, a torsion spring 42, a second fixed frame 43, a rotating block 44, a movable block 45, and a first fixed frame 46. One end of the rotating rod 41 passes through the main body 1 and is connected to the pressure plate 2. The rotating rod 41 is partially located on the lower side of the main body 1. The torsion spring 42 is mounted on the rotating rod 41 and is configured to store elastic potential energy when the pressure plate 2 is pressed down. Specifically, the second fixed frame 43 is fixedly connected to the main body 1. A snap-in groove 432 is provided on the side of the second fixed frame 43 near the pressure plate 2 for engaging one end of the torsion spring 42. One end of the torsion spring 42 engages with the snap-in groove 432, and the other end of the torsion spring 42 is connected to the pressure plate 2. The second fixed frame 43 is provided with a rotating hole 431, and at least a portion of the rotating block 44 is located within the rotating hole 431. The rotating block 44 is mounted on the rotating rod 41 and is in transmission connection with the rotating rod 41. The end of the rotating block 44 facing away from the pressure plate 2 is wedge-shaped.

[0046] A first fixed frame 46 is connected to the main body 1 and is provided with a square movable hole 461 for the movable block 45 to pass through. The two opposing sides of the movable block 45 are flat and contact the movable hole 461. The movable block 45 passes through the movable hole 461 and is slidably connected therewith. The end of the movable block 45 that is closest to the pressure plate 2 is wedge-shaped and abuts the wedge-shaped surface of the end of the rotating block 44 that is away from the pressure plate 2. The other end of the movable block 45 is provided with a push plate 451 that is used to press the injection assembly 5. The movable block 45 is provided with a socket 452. At least a portion of the rotating rod 41 is located in the socket 452, and the rotating rod 41 can freely rotate between the socket 452.

[0047] In this way, the rotating rod 41 is connected to the pressure plate 2, and the rotating rod 41 can rotate under the action of the pressure plate 2. One end of the wedge of the moving block 45 contacts one end of the wedge of the rotating block 44. When the rotating block 44 rotates, the contact position of the moving block 45 and the rotating block 44 changes, so that the moving block 45 slides relative to the first fixed frame 46, which presses the injection assembly 5, so that the injection assembly 5 can spray the cleaning liquid in the liquid storage tank 3. The setting of the moving hole 461 and the shape of the moving block 45 ensures that the moving block 45 will not rotate when the rotating block 44 rotates, thereby realizing the movement of the moving block 45. Under the action of the torsion spring 42, when the force on the pressure plate 2 is released, one end of the pressure plate 2 can rebound, driving the rotating block 44 back to its original position.

[0048] In an alternative embodiment, the torsion spring 42 is optimally configured. Those skilled in the art may select elastic torsion members of varying configurations based on specific practical scenarios, as long as they can reset after torsional displacement. Accordingly, the elastic torsion member being sleeved around the rotating rod 41 is not mandatory. Those skilled in the art may select the configuration and connection method of the elastic torsion member based on the specific application scenario. For example, the elastic torsion member may be a spring, with one end of the spring connected to the underside of the rotating end of the pressure plate 2.

[0049] In an alternative embodiment, the provision of the second fixing frame 43 is not necessary. Those skilled in the art can choose whether to provide the second fixing frame 43 and the specific structure of the second fixing frame 43 based on the specific application scenario. Of course, the second fixing frame 43 can also be omitted. The position of the rotating block 44 can also be fixed by connecting the rotating rod 41 with the rotating block 44.

[0050] In an alternative embodiment, the square shape of the movable hole 461 and the planar shapes of the two opposing sides of the movable block 45 are not required. Those skilled in the art can select the specific configurations of the movable hole 461 and the movable block 45 based on the specific application scenario. As long as the movable block 45 does not rotate relative to the movable hole 461, the movable hole 461 can be elliptical or polygonal, and the movable block 45 can be configured to be correspondingly shaped to prevent rotation relative to the movable hole 461. A ridge can also be provided within the movable hole 461 to prevent the movable block 45 from rotating, or a ridge can be provided on the inner surface of the movable block 45.

[0051] In an alternative embodiment, the setting of the push plate 451 is not necessary. Those skilled in the art can choose whether to set the push plate 451 and the specific structure of the push plate 451 based on the specific application scenario. Of course, the push plate 451 can also be omitted, and one end of the moving block 45 can be used to directly press the injection assembly 5 so that the injection assembly 5 can spray out the cleaning liquid.

[0052] In an alternative embodiment, the provision of the plug hole 452 is not necessary, and those skilled in the art can choose whether to provide the plug hole 452 and the specific structure of the plug hole 452 based on the specific application scenario. Of course, the plug hole 452 can also be not provided.

[0053] In an alternative embodiment, the provision of the transmission component 4 is not essential. Those skilled in the art can select the specific structure of the transmission component 4 based on the specific application scenario, or can select a transmission component 4 with other structures, as long as it can achieve the pressing of the injection component 5 so that the injection component 5 can transfer the cleaning liquid in the liquid storage tank 3 to the roller brush. For example, the transmission component 4 is a pressure rod, which passes through the side wall of the main body 1, one end of the pressure rod is fixedly connected to the pressure plate 2, and the other end of the pressure rod is wedge-shaped. The injection component 5 contacts the pressure rod, and the contact end is also wedge-shaped. When the pressure plate 2 drives the pressure rod to rotate, the purpose of squeezing the injection component 5 can also be achieved by setting two wedge-shaped contact surfaces.

[0054] See attached Figure 3 In a preferred embodiment, the spray assembly 5 includes a spray bracket 52, a fixed tube 53, a spray head 51, a spring, and a stopper. The spray bracket 52 is connected to the main body 1, the fixed tube 53 is provided with a spray inlet, and the spray head 51 is provided with a spray outlet 511. The fixed tube 53 is connected to the spray bracket 52, and the spray inlet is connected to the liquid storage tank 3. One end of the spray head 51 is movably connected to the fixed tube 53, and a spray cavity is formed between the fixed tube 53 and the spray head 51. The spring and the stopper are both located in the spray cavity. One end of the spring is connected to the spray head 51, and the other end of the spring is connected to the stopper. The spring is configured to store elastic potential energy when the movable block 45 is pressed into the fixed tube 53. The injection head 51 is configured to move toward the inside of the fixed tube 53 when squeezed by the movable block 45 under the action of an external force to compress the internal space of the fixed tube 53, so that the block blocks the injection inlet and the cleaning liquid located inside the fixed tube 53 is discharged from the injection outlet 511; and when the external force is removed, the injection head 51 moves toward the outside of the fixed tube 53 under the action of the spring to release the internal space of the fixed tube 53, so that the block disengages from the injection inlet and the cleaning liquid located in the liquid storage tank 3 flows into the inside of the fixed tube 53.

[0055] In this way, the mechanical structure realizes liquid spraying, which reduces the requirements for waterproofing compared to other liquid spraying methods. At the same time, the structure is simple and does not require connection to an external power supply, so that the base can be placed in any position. The overall stability is good, it is not easy to be damaged, and the maintenance cost is low.

[0056] It should be noted that the composition and structure of the spray assembly 5 are not mandatory. The spray assembly 5 only needs to be able to spray the liquid in the liquid storage tank 3. Those skilled in the art can select the specific structure of the spray assembly 5 based on the specific application scenario. For example, the fixed tube 53 can be a cylinder or a rectangular parallelepiped with open ends, and the stopper can be spherical or elliptical. The spray bracket 52 can also be omitted as long as the fixed tube 53 can be connected to the main body 1.

[0057] See attached Figure 1 and 3In a preferred embodiment, there are two cleaning tanks 11 and two spray assemblies 5, and the two cleaning tanks 11 are arranged in a one-to-one correspondence with the two spray assemblies 5; a liquid outlet 12 is provided on the cleaning tank 11, and the liquid outlet 12 is a flat mouth. The liquid outlet 12 is connected to the spray outlet 511. There are multiple liquid outlets 12, and the multiple liquid outlets 12 are provided on one side of the cleaning tank 11 and are arranged at intervals. A protrusion 111 is provided at the bottom of the cleaning tank 11. In this way, the two cleaning tanks 11 can be used to place a floor scrubber with two roller brushes, and the two spray assemblies 5 respectively provide cleaning liquid to the two cleaning tanks 11, making the scope of application wider. The setting of the liquid outlet 12 as a flat mouth can make the cleaning liquid evenly sprayed on the surface of the roller brush.

[0058] It should be noted that the provision of the liquid outlet 12 is not mandatory. Those skilled in the art can choose whether to provide the liquid outlet 12, as well as the number and specific structure of the liquid outlet 12 based on the specific application scenario. Of course, a circular or square liquid outlet 12 can be selected, multiple liquid outlets 12 can be provided, or no liquid outlet 12 can be provided. For example, the spray outlet 511 is connected to a delivery pipe, a nozzle is provided on the other end of the delivery pipe, and an outlet rack or outlet slot capable of accommodating the nozzle is provided on the main body 1, and the nozzle directly sprays the cleaning liquid onto the roller brush.

[0059] It should be further explained that the optimal number of cleaning tanks 11 and spray assemblies 5 is two, but of course, one cleaning tank 11 and one spray assembly 5 can also be provided. The provision of protrusions 111 is not mandatory, and those skilled in the art can choose whether to provide protrusions 111 and the specific structure of protrusions 111 based on specific application scenarios, as long as it can facilitate cleaning of the roller brush. Of course, it is also possible to provide bristles instead of protrusions 111, or to provide both protrusions 111 and bristles.

[0060] The present invention also provides a floor cleaning device assembly, comprising a floor cleaning device and the aforementioned base, wherein the lower portion of the floor cleaning device can be placed in the placement slot. Thus, when the pressing plate 2 is pressed down, it drives one end of the liquid outlet device to rotate, and the liquid outlet device sprays cleaning liquid toward the roller brush, so that the roller brush is cleaned under the action of the cleaning liquid, thereby achieving a better cleaning effect on the roller brush. Even if there is dirt that is difficult to wash off, it can be effectively removed under the action of the cleaning liquid, and the cleaning speed is also faster.

[0061] The following describes possible operating modes of this embodiment.

[0062] To clean the scrubber's roller brush, the scrubber is first placed in the placement slot. The user then presses the upper end of the pressure plate 2 with their foot, causing it to rotate. This in turn drives the rotating rod 41, which in turn stores elastic potential energy in the torsion spring 42. This in turn drives the rotating block 44, causing the contact position between the wedge-shaped end of the rotating block 44 and the wedge-shaped end of the movable block 45 to change, causing the movable block 45 to move away from the rotating block 44. The movable block 45 presses against the spray head 51, which then moves toward the interior of the fixed tube 53, compressing the interior space. This causes the block to block the spray inlet, allowing the cleaning fluid inside the fixed tube 53 to be discharged from the spray outlet 511. The fluid then flows through the spray outlet 511 and connects to the liquid outlet 12, where it is sprayed onto the roller brush, providing the cleaning fluid. The scrubber is then started, and the roller brush rotates, cleaning the roller brush via the protrusions 111 and the cleaning fluid. When the force on the pressure plate 2 is removed, under the action of the spring, the spray head 51 moves toward the outside of the fixed tube 53 to release the internal space of the fixed tube 53 to form a negative pressure, the block disengages from the spray inlet and the cleaning liquid in the liquid storage tank 3 flows into the interior of the fixed tube 53, and the elastic potential energy stored in the torsion spring 42 is released, lifting one end of the pressure plate 2 again to facilitate the next operation.
