[0057] 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 skilled in the art without creative effort are within the protection scope of the present utility model.

[0058] Please see Figures 1 to 5 This embodiment provides a water tank 3, a first mop assembly 2, and a cleaning robot 1. When the water tank 3 and the first mop assembly 2 are assembled onto the cleaning robot 1, the water tank 3 presses down on the first mop 2-2 on the first mop assembly 2 (including the mop bracket 2-1 and the first mop 2-2). The first mop 2-2 will deform and fit the mop bracket 2-1. The water tank 3 has a scraper and an opening. The scraper can contact the surface of the mop to scrape the liquid on the mop, so that it flows into the water tank 3 through the opening.

[0059] Please see Figure 3 The water storage tank 3 provided in this embodiment includes multiple side walls, a bottom wall, and a tank cover. The side walls and bottom wall form a liquid holding cavity for holding liquid. The tank cover is used to cover the side walls and together with the liquid holding cavity to form the water storage tank 3. Please see... Figure 4An opening is provided on the first side wall of the water storage tank 3. Below the opening, a first scraper 3-2 protrudes from the first side wall. The first scraper 3-2 is used to contact the mop surface to scrape the liquid on the mop surface, allowing the liquid to flow in along the opening on the first side wall. At this time, the liquid receiving cavity (water storage tank 3) formed by the side wall and the bottom wall is used to receive the liquid flowing in from the scraper on the first side wall. Optionally, the opening is a strip-shaped opening, with the first scraper 3-2 corresponding to the opening below it. The length of the first scraper 3-2 is equal to that of the opening, so that the scraped liquid can flow into the storage tank along the scraper and the opening. Since the side wall of the water storage tank 3 has the first scraper 3-2 and the opening, the liquid on the first mop assembly 2 can be directly scraped and stored. Compared with the existing method of first scraping the liquid into the sewage tank and then pumping the sewage into the sewage tank, there is no sewage tank-sewage box transfer process. This structure is simple, the risk of failure is reduced, and the cost is also low because no power source is needed for pumping.

[0060] Since the water tank 3 and the mop assembly have a mating relationship when assembled on the cleaning robot 1, the mop assembly that mates with the water tank 3 will be described first here to clarify this embodiment. This embodiment also provides a mop assembly, including an irregular mop bracket 2-1 (referred to as the first mop 2-2 in this embodiment) and the first mop 2-2 sleeved on the mop bracket 2-1. Please see... Figures 6 to 8 The mop support 2-1 includes a support part 2-5 and three rotating rollers 2-3.

[0061] The support portion 2-5 of the mop bracket 2-1 includes a first rectangular support member and a second rectangular support member fixed at an included angle. The first and second rectangular support members have a first set of roller shaft mounting members and a second set of roller shaft mounting members at their ends opposite to the fixed angle position, respectively, for mounting the rotating roller 2-3. The first and second rectangular support members on the support portion 2-5 have a third set of roller shaft mounting members at their ends at the fixed angle position, for mounting the rotating roller 2-3. The included angle between the first and second rectangular support members can be acute, right, or obtuse.

[0062] For the three rotating rollers 2-3 of the first mop assembly 2, the two ends of each rotating roller 2-3 are respectively fixed to the first to third sets of roller shaft mounting parts of the support part 2-5. The rotating roller 2-3 can rotate around its own rotation axis. After the first mop 2-2 is assembled onto the mop bracket 2-1, one or more rotating rollers 2-3 are driven by the power source to actively rotate around the rotation axis, which can drive the first mop 2-2 to rotate relative to the mop bracket 2-1. Due to the friction between the other rotating rollers 2-3 that are not driven by the power source and the first mop 2-2, they also passively rotate around the axis, thereby realizing the rotation (movement) of the mop on the mop bracket. At the same time, the mop moves relative to the water tank 3. The first scraper 3-2 on the first side wall of the water tank 3 is used to contact the mop surface on the mop assembly to scrape the liquid on the mop surface, so that the liquid flows into the water tank 3 through the opening on the first side wall, thereby collecting the wastewater of the mop on the mop assembly.

[0063] Please see Figures 6 to 8 The outer diameter of the mop holder 2-1 is much smaller than the inner diameter of the first mop 2-2, so the user can easily remove the first mop 2-2 from the mop holder 2-1; when installing the first mop 2-2 onto the mop holder 2-1, simply slip the first mop 2-2 onto the mop holder 2-1.

[0064] Please see Figure 1 , Figure 2 , Figures 4 to 8 When the first mop assembly 2 is assembled onto the cleaning robot 1, the first mop 2-2 on the first mop assembly 2 is compressed and deformed by the water tank 3 to conform to the mop bracket 2-1, forming multiple mop surfaces. One or more mop surfaces are used to clean the work surface (in some examples, the mop surface perpendicular to the ground can be used to clean baseboards). Driven by one or more rotating rollers 2-3 on the mop bracket 2-1, the first mop 2-2 moves relative to the water tank 3. The first scraper 3-2 on the first sidewall of the water tank 3 contacts the mop surface on the first mop assembly 2 to scrape liquid from the mop surface, allowing the liquid to flow into the water tank 3 along the first scraper 3-2 on the first sidewall. After the first mop assembly 2 is removed from the cleaning robot 1, because the mop itself is circular and made of silicone, it automatically springs back to its circular shape after being released from the pressure of the water tank 3. Users can easily understand how to directly replace the mop from the mop bracket without any training.

[0065] This embodiment also provides a cleaning robot 1, please see... Figure 1 , Figure 2 and Figure 4It includes the aforementioned first mop assembly 2 and water tank 3, as well as the machine body. The machine body includes a cover and a bottom shell, with a through-hole for receiving the first cleaning component between the cover and the bottom shell. The first mop assembly 2 is received in the first cleaning component receiving cavity on the machine body, and after being assembled into the first cleaning component receiving cavity, it can contact the working surface to clean the surface with the mop on the first mop assembly 2. The water tank 3 is also received in the first cleaning component receiving cavity on the machine body. Please see [link to relevant documentation]. Figures 4 to 8 When the water tank 3 is assembled into the receiving cavity of the first cleaning component, the water tank 3 will press down on the mop on the first mop assembly 2. The first mop 2-2 on the first mop assembly 2 will deform and tighten, fitting the mop bracket 2-1 to form an "L" shape. When the rotating roller 2-3 of the mop bracket 2-1 on the first mop assembly 2 is driven by the power source to rotate actively around the rotating axis, it will drive the first mop 2-2 to rotate relative to the mop bracket 2-1 and the water tank 3. The scraper on the first side wall of the water tank 3 contacts the mop surface and scrapes the liquid on the mop surface, so that the liquid flows into the water tank 3 through the opening on the first side wall, realizing the collection of liquid. Since the side wall of the water tank 3 has scraper and opening, it can directly scrape the liquid on the mop assembly and store the liquid. Compared with the existing method of scraping the liquid into the sewage tank first and then pumping the sewage into the sewage tank by a water pump, there is no sewage tank-sewage box transfer process. This structure is simple, the risk of failure is reduced, and the cost is also low because no power source is needed for water pumping.

[0066] Please see Figure 4 At the intersection of the outer surface of the water tank 3, the first side wall, and the bottom wall will press down on the first mop assembly 2, deforming the first mop 2-2. To facilitate the movement of the first mop 2-2 on the mop support 2-1, one or more idler wheels 3-1 are provided at the intersection of the outer surface of the water tank 3, the first side wall, and the bottom wall. The idler wheels 3-1 are used to contact the first mop 2-2 to facilitate the movement of the first mop 2-2 relative to the water tank 3, reducing the friction between the water tank 3 and the first mop 2-2. In some other examples, at the intersection of the outer surface of the water tank 3, the first side wall, and the bottom wall are provided with a roller that can rotate around an axis. The two ends of the roller are fixed relative to each other, and the roller contacts the first mop 2-2 to reduce the friction between the water tank 3 and the first mop 2-2, facilitating the movement of the first mop 2-2 relative to the water tank 3.

[0067] The first mop assembly 2 is assembled into the first cleaning assembly receiving cavity of the cleaning robot 1. The inner side of the first cleaning assembly receiving cavity has a limiting groove, and limiting posts are provided on both sides of the support portion 2-5 of the first mop assembly 2, perpendicular to the rotating roller 2-3. These limiting posts cooperate with the limiting groove on the first cleaning assembly receiving cavity to limit the first mop assembly 2 when it is assembled into the first cleaning assembly receiving cavity, thereby housing the first mop assembly 2 within the first cleaning assembly receiving cavity. (See...) Figures 9 to 11 The first mop assembly 2 is inserted into the inner cavity limiting grooves 1-2 at both ends of the first cleaning assembly receiving cavity of the cleaning robot 1 through the bracket limiting posts 2-4 at both ends, thereby achieving two-dimensional positioning. At this time, the first mop assembly 2 only has longitudinal degree of freedom.

[0068] In another example, the inner side of the first cleaning component receiving cavity has a limiting post, and the two sides of the first mop assembly 2 support 2-5 perpendicular to the rotating roller 2-3 are provided with limiting grooves, so that when the first mop assembly 2 is assembled into the first cleaning component receiving cavity, the limiting groove on the first mop assembly 2 cooperates with the limiting post on the first cleaning component receiving cavity to limit the first mop assembly 2 to be received into the first cleaning component receiving cavity.

[0069] In this embodiment, the water tank 3 is assembled into the first cleaning component receiving cavity of the cleaning robot 1. Both the water tank 3 and the first cleaning component receiving cavity have corresponding mounting devices to fix the water tank 3 into the cleaning component receiving cavity. One possible implementation method is that one side wall of the water tank 3 (outer wall of the water tank 3) also has a limiting protrusion 3-4, and the other side wall has a buckle 3-5. Please see... Figures 1 to 3 , Figures 9 to 11 The first cleaning component receiving cavity has limiting grooves 1-3 on both sides and a buckle 1-4 on the other side wall. When the water tank 3 is installed in the first cleaning component receiving cavity, the limiting protrusion 3-4 of the water tank 3 is engaged in the limiting groove 1-3 of the first cleaning component receiving cavity, and the buckle 3-5 of the water tank 3 is engaged in the buckle 1-4 of the first cleaning component receiving cavity, thereby fixing the water tank 3 into the first cleaning component receiving cavity.

[0070] Please see Figures 9 to 11After tilting the water tank 3 so that its limiting protrusion 3-4 engages with the limiting groove 1-3 of the first cleaning component's receiving cavity, align the buckles 3-5 on the outer wall of the water tank 3 with the buckles 1-4 on the first cleaning component's receiving cavity. Then press the water tank 3. At this time, the two buckles 3-5 on the water tank 3 will engage with the buckles 1-4 on the first cleaning component's receiving cavity, thus fixing the water tank 3 to the cleaning robot 1. By fixing the water tank 3 to the cleaning robot 1, the idler wheel 3-1 on the water tank 3 can forcefully press the first mop 2-2. At this time, the first mop assembly 2 and the water tank 3 achieve longitudinal mutual positioning, thereby realizing three-dimensional fixation between the two sets. Please see... Figure 1 , Figure 2 as well as Figure 4 After the first mop assembly 2 and the water tank 3 are fixed, there is a certain amount of interference between the first scraper 3-2 on the first side wall of the water tank 3 and the first mop 2-2. When the rotating roller 2-3 of the first mop assembly 2 rotates the mop, the first scraper 3-2 on the water tank 3 scrapes the mop, thereby scraping the liquid off the first mop 2-2 and allowing it to flow into the water tank 3 through the opening.

[0071] To fix the water tank 3 into the cleaning component receiving cavity, another possible method is as follows: one side wall of the water tank 3 has a limiting groove 1-3, and the other side wall has a buckle 3-5. The two sides of the corresponding cleaning component receiving cavity have limiting protrusions 3-4, and the other side wall has a fastening position 1-4. When the water tank 3 is installed in the cleaning component receiving cavity, the limiting protrusions 3-4 of the cleaning component receiving cavity are engaged with the limiting groove 1-3 of the water tank 3, and the buckles 3-5 of the water tank 3 are engaged with the fastening positions 1-4 of the cleaning component receiving cavity.

[0072] The above refers to the scraper on one side wall of the water tank 3 used to scrape liquid off the mop surface of the mop assembly. In some other examples, the cleaning robot 1 may have two mop assemblies; please see [link to relevant documentation]. Figure 1 and Figure 2 The first mop assembly 2 and the second mop assembly 4 in the water tank 3 have scraping strips to scrape the liquid off the first mop assembly 2 and the second mop assembly 4, respectively. For this example, this embodiment also provides a cleaning robot 1, including the first mop assembly 2 described above, as well as the water tank 3, the machine body, and the second mop assembly 4. In this embodiment, the terms "first," "second," and "third," etc., are only used to distinguish the various components and have no actual meaning.

[0073] In this example, an opening is provided on the first side wall of the water storage tank 3, please see Figure 4 The opening on the first side wall has a first scraper 3-2 protruding from the first side wall. Additionally, an opening is also provided on the second side wall of the water storage tank 3. (See attached image.) Figure 3The opening on the second sidewall has a second scraper 3-3 protruding from the second sidewall, please see... Figure 5 The second scraper 3-3 is used to scrape liquid from the surface of the second mop assembly 4, allowing the liquid to flow into the water tank 3 through an opening on the second side wall. The machine body also has a through-hole second cleaning assembly receiving cavity into which the second mop assembly 4 is received, and the second mop assembly 4 contacts the working surface to clean the cleaning surface. In this embodiment, the second scraper 3-3 on the water tank 3 is used to scrape liquid from another mop surface (different from the mop surface contacted by the scraper on the first side wall, such as the mop surface of the second mop assembly 4), allowing the liquid to flow into the water tank 3 along the scraper on the second side wall. This allows one water tank 3 to collect liquid from the mops of two mop assemblies, simplifying the liquid collection structure and reducing the risk of equipment failure.

[0074] like Figures 9 to 11 The image shown is of cleaning robot 1. Figures 12 to 14 The diagram shows the second mop assembly 4. The second cleaning assembly housing of the cleaning robot 1 has two slide rails 1-1. The second mop assembly 4 has a sliding sleeve 4-3, which is inserted into the slide rails 1-1 to fix the second mop assembly 4 relative to the cleaning robot 1. The second mop assembly 4 is used to clean stains around the cleaning robot 1; it is also referred to as an edge cleaning assembly.

[0075] like Figure 14 The second mop assembly 4 is equipped with a geared motor 4-4 and a transmission component 4-5. After the geared motor 4-4 rotates, the power is transmitted to the drive shaft 4-6 through the transmission component 4-5. Then, the drive shaft 4-6 transmits the power to the second mop 4-2 through the auxiliary shaft 4-7 via friction or rack 4-1, which can realize the forward and reverse rotation of the mop and achieve the purpose of cleaning the working surface (ground).

[0076] like Figure 1 , Figure 2 as well as Figure 14 The cleaning robot 1 has a fixed geared motor assembly 1-6. The gear on the geared motor assembly 1-6 meshes with the rack 4-1 on the bracket 2-1 of the second mop 4-2. At this time, the geared motor assembly 1-6 can slide the second mop assembly 4 back and forth, realizing the retraction and extension functions of the second mop assembly 4. When the second mop assembly 4 extends, it can clean the corner areas that the first mop assembly 2 cannot reach. When the second mop assembly 4 retracts, it is squeezed by the scraper on the water tank 3. As the mop rotates, the scraper scrapes the liquid on the surface of the mop and smooths it into the internal cavity of the water tank 3.

[0077] The water tank 3, the first mop assembly 2, the second mop assembly 4, and the cleaning robot 1 described above enable the cleaning robot 1 to directly flow the cleaning liquid on the mop into the water tank 3 during the mop cleaning process. This replaces the existing structure that requires a squeegee to temporarily hold the cleaning liquid and the additional structure that requires an air pump to draw the cleaning liquid into the water tank 3. This greatly simplifies the structure, significantly reduces costs, and also reduces the probability of machine errors.

[0078] The technical features of the above embodiments can be combined in any way. For the sake of brevity, not all possible combinations of the technical features in the above embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.

[0079] The embodiments described above are merely illustrative of several implementations of this utility model, and while the descriptions are relatively specific and detailed, they should not be construed as limiting the scope of this utility model patent. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of this utility model, and these all fall within the protection scope of this utility model. Therefore, the protection scope of this utility model patent should be determined by the appended claims.
