Therefore, the features defined as "first" and "second" may explicitly or implicitly include at least one of the features. In the description of the present application, "multiple" means at least two, such as two, three, etc., unless otherwise clearly and specifically defined. The embodiments described below with reference to the drawings are exemplary and are intended to be used to explain the present application, and cannot be understood as limiting the present application.

[0029] As shown in Figures 1 and 2, a cleaning device according to an embodiment of the present application includes a body 1 and a floor brush 2. The floor brush 2 includes a floor brush housing, which is provided with a roller brush device 23 and a sewage suction port (not shown in the figure). Dirt on the floor is cleaned by the roller brush device and the sewage suction port. The floor brush housing includes an interconnected floor brush upper cover 21 and a floor brush lower cover 22. The floor brush upper cover 21 and the floor brush lower cover 22 enclose an installation space 24 within the floor brush. The installation space 24 is provided with an electrolyzed water sterilization device 4 and a water pump 3.

[0030] As shown in Figures 3 and 4, the electrolytic water sterilization device 4 includes a box body, in which an electrolysis chamber 5 is provided. The box body is also provided with a water inlet 51 and a water outlet 52 in fluid communication with the electrolysis chamber 5. The water inlet 51 is connected to a clean water tank (not shown) on the body 1 that stores cleaning liquid through an infusion tube 11, and the water outlet 52 is connected to the water pump 3 through the infusion tube 11. The electrolysis chamber 5 is also provided with an electrode plate assembly 6 for electrolyzing the cleaning liquid. During operation, the water pump 3 generates negative pressure by suction, causing the cleaning liquid to flow from the clean water tank into the electrolysis chamber 5 of the sterilization device 4. The electrode plate assembly 6 in the electrolysis chamber 5 electrolyzes the cleaning liquid into a cleaning liquid containing a bactericidal substance. The electrolyzed cleaning liquid flows out through the water outlet 52 and is eventually distributed by the water pump 3 to the roller brush 23, thereby deeply cleaning the floor.

[0031] The sterilization device 4 and the water pump 3 are distributed on both sides of the floor brush installation space 24, so that the internal installation space 24 of the floor brush is not too crowded, and there is enough installation space to arrange and install connectors such as wires and infusion tubes 11. Referring to Figures 5 to 7 at the same time, the box body 41 of the sterilization device 4 includes a detachable upper shell 411 and a lower shell 412, and the upper shell 411 and the lower shell 412 are sealed and enclosed to form an electrolysis chamber 5. The electrode plate assembly 6 includes a stacked first electrode plate 61, an insulating plate 63 and a second electrode plate 62. The first electrode plate 61 and the second electrode plate 62 are respectively connected to the positive and negative poles of the power supply. The insulating plate 63 is sandwiched between the first electrode plate 61 and the second electrode plate 62 to prevent direct contact between the first electrode plate 61 and the second electrode plate 62, causing a short circuit. In this embodiment, a number of limiting ribs 413 are provided on the side walls of the lower shell 412, and a number of support platforms 414 are provided on the bottom wall of the lower shell 412. During installation, the first electrode plate 61 is placed on the support platform 414 to be separated from the bottom wall of the lower shell 412; then the insulating plate 63 is placed on the first electrode plate 61, and finally the second electrode plate 62 is placed on the insulating plate 63; the side walls of the first electrode plate 61, the insulating plate 63 and the second electrode plate 62 are all in contact with the limiting ribs 413, which not only prevents the electrode plate assembly 6 from moving in the circumferential direction, but also separates the electrode plate assembly 6 from the side walls of the box body.

[0032] In this embodiment, the upper shell 411 is also provided with a positioning plate 415 extending into the lower shell 412. When the upper shell 411 is assembled to the lower shell 412, the positioning plate 415 can just abut the upper surface of the second electrode plate 62, thereby completing the installation of the electrode plate assembly 6 with the cooperation of the limiting ribs 413, the positioning plate 415 and the support platform 414. A plurality of through holes are provided through the first electrode plate 61 and the second electrode plate 62 to facilitate better flow of water through the electrode plate assembly 6, thereby improving the electrolysis efficiency. The insulating plate 63 is in the shape of a "wireframe" with a hollow center, which can contact the limiting ribs 413 while reducing the impact on the flow of water through the electrode plates.

[0033] The number of the first electrode plates 61 and the second electrode plates 62 is not limited, and the connection between the first electrode plates 61 and the second electrode plates 62 and the positive and negative poles of the power supply is not fixed and can be adjusted according to actual conditions. In this embodiment, as shown in Figures 3, 6 and 7, a group of first electrode plates 61 and second electrode plates 62 are provided in the electrolysis chamber 5, and a mounting cavity 7 for mounting components is provided at the bottom of the lower shell 412. Two mounting holes 71 are provided through the lower shell 412 to connect the mounting cavity 7 and the electrolysis chamber 5. The first electrode plates 61 and the second electrode plates 62 each have a bent connecting portion 64, which enters the mounting cavity 7 from the mounting hole 71, thereby electrically connecting to the circuit board or wire in the mounting cavity 7. After installation is completed, the mounting cavity 7 can be filled with colloid for packaging.

[0034] Continuing to refer to Figures 3 and 4, during operation, the cleaning liquid enters the electrolysis chamber 5 from the water inlet 51, the electrode plate assembly 6 electrolyzes the cleaning liquid, and the electrolyzed cleaning liquid flows out of the electrolysis chamber 5 from the water outlet 52, and is finally distributed by the water pump 3 to the roller brush 23 to clean the floor. In this embodiment, the electrolysis chamber 5 is also provided with a negative pressure chamber 8 that is fluidically connected to the electrolysis chamber 5. The negative pressure chamber 8 includes a cavity wall 81, which extends in a vertical direction, and the end of the cavity wall 81 away from the box body 41 is an open end 82. The negative pressure chamber 8 is fluidically connected to the electrolysis chamber 5 through the open end 82. The water outlet 52 is provided in the negative pressure chamber 8 and is away from the open end 82. The water outlet 52 is fluidically connected to the negative pressure chamber 8. After the cleaning liquid is electrolyzed by the electrode plate assembly 6 in the electrolysis chamber 5, it enters the negative pressure chamber 8 and then flows out from the water outlet 52.

[0035] Specifically, as shown in Figures 3 and 4 , in this embodiment, a partition 811 is provided in the electrolysis chamber 5 , extending vertically. The partition 811 is disposed on the top wall of the electrolysis chamber 5 , and the partition 811 and the box body 41 enclose a negative pressure chamber 8 . The bottom end of the partition 811 (i.e., the end away from the box body 41 ) is an open end 82 . The electrode plate assembly 6 is disposed below the open end 82. During operation, the water pump 3 draws air from the water outlet 52, thereby forming a negative pressure in the electrolysis chamber 5, causing the cleaning liquid to enter the electrolysis chamber 5 from the water inlet 51. The cleaning liquid is electrolyzed when it contacts the electrode plate assembly 6. As the water level in the electrolysis chamber 5 rises, the electrolyzed cleaning liquid reaches the open end 82 of the partition 811. Since the water outlet 52 is disposed in the negative pressure chamber 8, the negative pressure chamber 8 is in a negative pressure state. Therefore, the cleaning liquid can be sucked into the negative pressure chamber 8 from the open end 82 and then flow out from the water outlet 52. When the cleaning device is actually in use, the movement of the floor brush 2 on the ground causes the cleaning liquid in the electrolysis chamber 5 to slosh, causing the liquid level in the electrolysis chamber 5 to slosh, thereby sometimes preventing the water pump 3 from extracting the cleaning liquid. When the water pump 3 fails to extract the cleaning liquid or does not extract a sufficient amount of cleaning liquid, the distance traveled by the floor brush 2 on the floor is not fully cleaned by the cleaning liquid, thereby affecting the cleaning effect of the cleaning device. Therefore, by setting up the negative pressure chamber 8, the cleaning liquid first reaches the electrolysis chamber 5, and then the negative pressure chamber 8 absorbs water from the cleaning liquid in the electrolysis chamber 5. In this way, even if shaking occurs, there is still cleaning liquid in the negative pressure chamber 8, and the water pump 3 can still stably pump water to the roller brush 23, thereby improving the cleaning effect.

[0036] In an embodiment not shown in the figure, multiple partitions 811 can also be provided, and the multiple partitions 811 are interconnected to enclose a negative pressure chamber 8. In order to enable the water pump 3 to stably absorb water, it is preferred to set the size of the negative pressure chamber 8 to be larger than the diameter of the outlet pipe 521 connected to the water outlet 52. Furthermore, in actual production, the area of ​​the open end 82 of the negative pressure chamber 8 should be as large as possible to better contact the liquid surface in the electrolysis chamber 5, so that even if the liquid surface shakes, the negative pressure chamber 8 can still absorb a sufficient amount of water from the electrolysis chamber 5. As shown in Figure 4 of this embodiment, the front and rear ends of the partition 811 are connected to the box body 41. The partition 811 and the box body wall together form the side wall of the negative pressure chamber 8. The open end 82 is located at the bottom of the side wall, thereby dividing the upper space of the electrolysis chamber 5 into two areas, increasing the area of ​​the open end 82, and allowing the cleaning liquid to be stably pumped into the water pump 3.

[0037] As shown in Figure 8, in another embodiment, a partition 811 is arranged on the bottom wall of the electrolysis chamber 5, and the partition 811 and the box body 41 are enclosed to form a negative pressure chamber 8, and the water outlet 52 is arranged in the negative pressure chamber 8 near the bottom wall. During operation, the cleaning liquid level in the electrolysis chamber 5 gradually rises. When it rises to the open end 82, the cleaning liquid overflows into the negative pressure chamber 8 and then flows out from the water outlet 52. When the brush 2 is shaken in this way, even if the liquid level in the electrolysis chamber 5 shakes, it will not affect the water pump 3 from absorbing the cleaning liquid. In this embodiment, the position of the electrode plate assembly 6 is not limited. It is preferred to arrange the electrode plate assembly 6 above the water inlet 51 or basically flush with the water inlet 51, so that the water flows into the negative pressure chamber 8 after electrolysis through the electrode plate assembly 6.

[0038] As shown in Figures 3 and 4 , the water outlet 52 is provided through the side wall of the box body 41. This allows the water outlet pipe 521 to be located on one side of the box body 41. The water outlet pipe 521 can extend generally horizontally (including horizontally tilted upward or horizontally tilted downward). This not only facilitates the suction of airflow from the negative pressure chamber 8, but also allows for better connection with the infusion tube 11, reducing pipe bending. The position of the water inlet 51 is not limited and can be adjusted during design based on the mounting structure of the floor brush 2, water inlet pipe 511, and other components. In this embodiment, the electrolysis chamber 5 is also provided with a display light 9. The display light 9 is connected to the control system of the cleaning device and illuminates when the sterilization device 4 is operating. A transparent or translucent first observation window 91 is provided at least partially on the box body 41. Through this first observation window 91, the electrolysis of the cleaning liquid in the electrolysis chamber 5 and the light of the display light 9 can be observed. The box body 41 can also be made entirely of transparent or translucent materials.

[0039] As shown in Figure 9, a second observation window 92 is provided on the floor brush cover 21. When the cleaning device is in use, the user can observe the electrolysis of the cleaning liquid in the electrolysis chamber 5 and the light of the indicator light 9 through the second observation window 92. Specifically, during installation, the top wall of the sterilization device 4 box body 41 is substantially in contact with the floor brush cover 21, so that the first observation window 91 and the second observation window 92 can be close to each other, thereby facilitating the user to observe the interior of the electrolysis chamber 5 and the light of the indicator light 9 through the first observation window 91 and the second observation window 92. In this embodiment, the second observation window 92 is configured as a hollow structure on the floor brush cover 21 (refer to Figure 2), and the first observation window 91 is exposed from the second observation window 92. The structure is simple and convenient for production and installation. In other embodiments, the second observation window 92 can also be configured to be made of a transparent or translucent material. To facilitate user observation, it is preferably arranged that the second observation window 92 is located on the rear side of the floor brush cover 21 and is tilted upward.

[0040] Continuing to refer to Figure 9, in this embodiment, the upper shell 411 of the sterilization device 4 abuts against the upper cover 21 of the floor brush, and the lower shell 412 of the sterilization device 4 abuts against the lower cover 22 of the floor brush. The lower cover 22 of the floor brush is also provided with a limiting groove 10 for installing the sterilization device 4. The shape and size of the limiting groove 10 are set according to the lower shell 412, thereby limiting the box body 41 in the circumferential direction to prevent the box body 41 from moving horizontally.

[0041] The sterilizing device 4 and floor brush 2 of the present application can stably supply water to the roller brush 23 during actual use, thereby improving the cleaning effect. It is also convenient for the user to observe the electrolysis status of the sterilizing device 4 and to know the working status of the sterilizing device 4 and the cleaning device through the display light 9, which is convenient for the user to use.

[0042] The above-described embodiments merely represent several implementation methods of the present application. While the descriptions are relatively specific and detailed, they should not be construed as limiting the scope of the present invention. It should be noted that a person of ordinary skill in the art may make various modifications and improvements without departing from the spirit of the present invention, all of which fall within the scope of protection of the present invention. Therefore, the scope of protection of the present invention shall be determined by the appended claims.
