Description

Technical Field

[0001] This application relates to the field of electrical technology, and in particular to a cleaning disc, a cleaning disc assembly, and a base station. Background Technology

[0002] With the development of smart homes, various cleaning devices have been widely used in households, reducing people's cleaning burden. Among them, common cleaning devices, such as cleaning robot systems, are usually equipped with a cleaning robot and a base station. When the cleaning robot finishes its work, runs out of power, has insufficient water in its internal water tank, or has a full water collection tank, the cleaning robot can move to the base station. The base station can charge the cleaning robot, replenish its water supply, collect the water discharged by the robot, and clean the cleaning components on the robot.

[0003] In related technologies, after the cleaning robot moves into the base station, the cleaning component inside the robot can rotate within the base station's cleaning tray. This allows protrusions such as cleaning ribs on the cleaning tray to scrape off dirt adhering to the cleaning component as it rotates. However, dirt that falls off the cleaning component can easily remain on the cleaning tray. Utility Model Content

[0004] The purpose of this application is to provide a cleaning tray, a cleaning tray assembly, and a base station, in order to solve the technical problem that dirt can easily remain on the cleaning tray.

[0006] The beneficial effects of the cleaning tray provided in the first aspect of this application are as follows: Since the bottom of the cleaning tank can contact the cleaning component, part of the cleaning component will cover the opening of the water inlet tank, and the wall of the water inlet tank can contact the cleaning component. As the cleaning component rotates, it will move relative to the water inlet tank, so that the cleaning component moves relative to the wall of the water inlet tank, thereby allowing the wall of the water inlet tank to scrape and wash the cleaning component, so that the dirt attached to the cleaning component is scraped off by the wall of the water inlet tank and falls into the water inlet tank; and when the cleaning component rotates relative to the cleaning tray, the rotating cleaning component can contact and scrub the bottom of the cleaning tank, so as to transfer the dirt on the bottom of the cleaning tank to the water inlet tank, thereby reducing the dirt remaining on the cleaning tray.

[0010] In some embodiments, the first rib further includes a transition portion, which is connected to the scraping portion and the bottom of the cleaning tank.

[0011] In some embodiments, the transition portion is smoothly connected to the bottom of the cleaning tank.

[0012] In some embodiments, the protrusion further includes a plurality of protrusions spaced apart along the extension direction of the water inlet channel, the protrusions being located upstream of the water inlet channel in the rotation direction of the cleaning component.

[0013] In some embodiments, the protrusion further includes a second rib, which protrudes toward the opening of the cleaning tank and is smoothly connected to the bottom of the cleaning tank.

[0014] In some embodiments, the cleaning tray is further provided with a water outlet trough, the opening of which is located at the bottom of the cleaning trough, wherein the water inlet trough is connected to the water outlet trough.

[0015] In some embodiments, the cleaning tray is further provided with a guide groove, which is connected to the cleaning tank and the water outlet tank, and the bottom of the guide groove is inclined from the water inlet tank to the water outlet tank.

[0016] To achieve the above objectives, the technical solution adopted in the second aspect of this application is: a cleaning tray assembly, including the cleaning tray of the first aspect embodiment described above.

[0017] The beneficial effect of the cleaning tray assembly provided in the second aspect of this application is that: by applying the cleaning tray of the first aspect embodiment to the cleaning tray assembly, when the cleaning component rotates relative to the cleaning tray assembly, the rotating cleaning component can contact and scrub the bottom of the cleaning tank, so as to transfer the dirt on the bottom of the cleaning tank to the water inlet tank, thereby reducing the dirt remaining on the cleaning tray assembly.

[0018] In some embodiments, the cleaning tray assembly further includes a filter screen located downstream of the water inlet tank in the direction of water flow.

[0019] To achieve the above objectives, the technical solution adopted in the third aspect of this application is: a base station, including the cleaning disk of the first aspect embodiment, or including the cleaning disk assembly of the second aspect embodiment.

[0030] To make the objectives, technical solutions, and advantages of this application clearer, the following detailed description is provided in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative and not intended to limit the scope of this application.

[0031] It should be noted that when a component is referred to as being "fixed to" or "set on" another component, it can be directly on or indirectly on that other component. When a component is referred to as being "connected to" another component, it can be directly connected to or indirectly connected to that other component.

[0032] Furthermore, the terms "first" and "second" are used for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the number of technical features indicated. Thus, a feature defined as "first" or "second" may explicitly or implicitly include one or more of that feature. In the description of this application, "multiple" means two or more, unless otherwise explicitly specified.

[0033] In this specification, references to "one embodiment," "some embodiments," or simply "embodiment" mean that one or more embodiments of this application include a specific feature, structure, or characteristic described in connection with that embodiment. Therefore, the phrases "in one embodiment," "in some embodiments," "in other embodiments," "in still other embodiments," etc., appearing in different parts of this specification do not necessarily refer to the same embodiment, but rather mean "one or more, but not all, embodiments," unless otherwise specifically emphasized. Furthermore, in one or more embodiments, specific features, structures, or characteristics may be combined in any suitable manner.

[0034] In related technologies, the cleaning structure in a base station includes a cleaning tray and a cleaning support. The cleaning tray has a cleaning tank, and the cleaning support is mounted on the cleaning tray, including cleaning ribs housed within the cleaning tank. After the cleaning robot moves into the base station, the cleaning component of the robot can rotate within the cleaning tank, and the cleaning component can abut against the cleaning ribs and rotate relative to the cleaning ribs, allowing the cleaning ribs to scrape off the dirt attached to the cleaning component. The dirt scraped off by the cleaning ribs falls to the bottom of the cleaning tank. Because the cleaning tray does not have a self-cleaning function, dirt easily accumulates in the cleaning tank. The dirt accumulated in the cleaning tank requires frequent manual cleaning by the user, causing inconvenience.

[0035] It should be noted that currently, to reduce dirt accumulation in the cleaning tray, a scraper-based active self-cleaning solution is used. This involves adding a scraper self-cleaning module to the base station. The module includes a drive component and a scraper. The scraper is positioned inside the cleaning tank and contacts the bottom of the tank. The drive component is located below the cleaning tray, and its drive end is connected to the scraper. Driven by the drive component, the scraper moves along the bottom of the cleaning tank to clean it, ensuring the tank bottom remains clean. However, the scraper self-cleaning module occupies space within the base station, hindering miniaturization. Furthermore, adding the scraper self-cleaning module increases the base station's structure, thereby increasing manufacturing difficulty and cost.

[0036] In view of the above problems, this application provides a cleaning tray, a cleaning tray assembly, and a base station, aiming to solve the technical problem that dirt is easily left on the cleaning tray.

[0037] To illustrate the technical solution of this application, the following description is provided in conjunction with specific accompanying drawings and embodiments.

[0038] Please refer to Figure 1 and Figure 2 This application provides a cleaning tray 1, which is provided with a cleaning tank 11 for accommodating cleaning parts, and the bottom 111 of the cleaning tank 11 is used to contact the cleaning parts. The bottom of the cleaning tank 11 is provided with a water inlet 12, and the opening of the water inlet 12 is opened on the bottom 111 of the cleaning tank 11.

[0039] It should be noted that the cleaning component is disc-shaped, meaning it has a flat structure with a circular, elliptical, or polygonal shape. The cleaning component has a cleaning surface facing the surface to be cleaned (such as a floor or countertop). This cleaning surface is used to wipe the surface and can absorb dust, food residue, and other dirt. Generally, cleaning robots include a water spray component. This component provides water to the cleaning component to wet it, softening the dirt on the surface to be cleaned so that it can be wiped away by the cleaning surface.

[0040] When cleaning the cleaning component using the cleaning tray 1 of this application embodiment, the cleaning component is contained in the cleaning tank 11, and the cleaning component is in contact with the bottom 111 of the cleaning tank 11, and the cleaning component rotates relative to the cleaning tray 1. Since the bottom 111 of the cleaning tank 11 can contact the cleaning components, some of the cleaning components will cover the opening of the water inlet tank 12, and the wall 121 of the water inlet tank 12 can contact the cleaning components. As the cleaning components rotate, they will move relative to the water inlet tank 12, so that the cleaning components move relative to the wall 121 of the water inlet tank 12. This allows the wall 121 of the water inlet tank 12 to scrape and clean the cleaning components, so that the dirt attached to the cleaning components is scraped off by the wall 121 of the water inlet tank 12 and falls into the water inlet tank 12. Furthermore, when the cleaning components rotate relative to the cleaning tray 1, the rotating cleaning components can contact and scrub the bottom 111 of the cleaning tank 11, so as to transfer the dirt on the bottom 111 of the cleaning tank 11 to the water inlet tank 12, thereby reducing the dirt remaining on the cleaning tray 1.

[0041] It should be noted that the rotating cleaning component can contact and scrub the bottom 111 of the cleaning tank 11 to transfer the dirt on the bottom 111 of the cleaning tank 11 to the water inlet tank 12. This means that the cleaning surface on the rotating cleaning component adsorbs the dirt on the bottom 111 of the cleaning tank 11, and the rotating cleaning component moves the dirt to the wall 121 of the water inlet tank 12, so that the dirt is scraped off by the wall 121 of the water inlet tank 12 and falls into the water inlet tank 12; or the rotating cleaning component pushes the dirt on the bottom 111 of the cleaning tank 11 and pushes the dirt on the bottom 111 of the cleaning tank 11 into the water inlet tank 12.

[0042] Optionally, when the cleaning component is housed in the washing tank 11, the cleaning component can abut against the bottom 111 of the washing tank 11, so that part of the cleaning component can be housed in the water inlet tank 12. That is, part of the cleaning component is staggered with the wall 121 of the water inlet tank 12 (the cleaning component and the wall 121 of the water inlet tank 12 are interference fit). Therefore, when the cleaning component rotates, the scraping effect of the wall 121 of the water inlet tank 12 on the cleaning component is more significant, which is more conducive to scraping the dirt attached to the cleaning component into the water inlet tank 12. In addition, the abutment between the cleaning component and the bottom 111 of the washing tank 11 allows the cleaning surface to fully contact the bottom 111 of the washing tank 11. Therefore, when the cleaning component rotates, the cleaning surface can fully scrub the dirt on the bottom 111 of the washing tank 11, which is more conducive to pushing the dirt on the bottom 111 of the washing tank 11 into the water inlet tank 12.

[0043] It should be noted that when using the cleaning tray 1 of this embodiment to clean the cleaning components, water will flow into the water inlet 12. The water flow can rinse the water inlet 12 to flush out dirt that has fallen into the water inlet 12, thereby reducing the accumulation of dirt in the water inlet 12. Furthermore, the water flow can also contact the cleaning components to wet them, which helps to scrape off the dirt on the cleaning components from the wall 121 of the water inlet 12. The wetted cleaning components can also wet the dirt on the bottom 111 of the cleaning tank 11, making it easier for the cleaning surface to wipe away the dirt from the bottom 111 of the cleaning tank 11.

[0044] Please refer to Figure 1 In some embodiments, the cleaning disc 1 is provided with two cleaning tanks 11 so that the cleaning disc 1 can be applied to a cleaning robot system with two cleaning components.

[0045] Please refer to Figure 1 In some embodiments, the bottom 111 of the cleaning tank 11 is also provided with a protrusion 13, which protrudes upward from the bottom 111 of the cleaning tank 11 along the direction of the opening of the cleaning tank 11.

[0046] In the above embodiment, the protrusion 13 protrudes from the bottom 111 of the cleaning tank 11 in the orientation of the opening of the cleaning tank 11, so that the protrusion 13 can be interference-fitted with the cleaning component contained in the cleaning tank 11. When the cleaning component rotates, the cleaning component moves relative to the protrusion 13. On the one hand, the protrusion 13 can play the role of scrubbing the cleaning component, so as to scrub out the dirt attached to the deeper part of the cleaning component or scrub it to the surface of the cleaning component, and then scrape it off by the tank wall 121 of the water inlet tank 12 and fall into the water inlet tank 12 in the subsequent process, so as to more thoroughly clean the cleaning component, thereby enhancing the cleaning effect of the cleaning tray 1; on the other hand, the protrusion 13 can work together with the tank wall 121 of the water inlet tank 12 to scrape off the dirt on the cleaning component.

[0047] Please refer to Figure 2 , Figure 3 and Figure 4 In some embodiments, the protrusion 13 includes a first rib 131, which is located downstream of the water inlet 12 in the rotation direction of the cleaning component, and protrudes from the opening of the water inlet 12 in the orientation of the opening of the water inlet 12.

[0048] In the above embodiment, since the first rib 131 protrudes from the opening of the water inlet trough 12, it can be interference-fitted with the cleaning component housed in the cleaning tank 11. Therefore, when the cleaning component rotates, the first rib 131 can scrape the cleaning component, causing the dirt attached to the cleaning component to be scraped off. The scraping effect of the first rib 131 on the cleaning component is more significant than that of the tank wall 121 of the water inlet trough 12, which is more conducive to scraping off the dirt attached to the cleaning component, so as to clean the cleaning component more thoroughly and thus enhance the cleaning effect of the cleaning tray 1. Furthermore, since the first rib 131 is located downstream of the water inlet trough 12 in the rotation direction of the cleaning component, the dirt scraped off by the first rib 131 can fall into the water inlet trough 12, thereby reducing the probability that the dirt scraped off by the first rib 131 will fall onto the bottom 111 of the cleaning tank 11, thus reducing the risk of dirt accumulating on the bottom 111 of the cleaning tank 11.

[0049] It should be noted that when the cleaning part is along Figure 2 When the cleaning part rotates clockwise, its rotation direction is the X direction shown in the diagram. The cleaning part rotates along... Figure 2 When the cleaning part rotates counterclockwise, the rotation direction of the cleaning part is the Y direction in the figure.

[0050] Please refer to Figure 3 and Figure 4 In some embodiments, the first rib 131 includes a scraping part 1311, which is connected to the wall 121 of the water inlet tank 12.

[0051] With the above arrangement, the dirt scraped off by the first rib 131 can flow smoothly along the scraping part 1311 and flow to the wall 121 of the water inlet tank 12, so that the dirt scraped off by the first rib 131 can flow smoothly into the water inlet tank 12.

[0052] Please refer to Figure 3 and Figure 4 In some embodiments, the first rib 131 further includes a transition portion 1312, which is connected to the scraping portion 1311 and the bottom 111 of the cleaning tank 11.

[0053] The above settings can reduce the damage to the cleaning component caused by the first rib 131.

[0054] In the above embodiment, the transition portion 1312 is an arc surface that protrudes into the opening of the cleaning tank 11.

[0055] Please refer to Figure 3 In some embodiments, the transition portion 1312 is smoothly connected to the bottom 111 of the cleaning tank 11.

[0056] The above-mentioned arrangement can prevent the formation of sharp corners at the contact point between the first rib 131 and the bottom 111 of the cleaning tank 11, thereby preventing the formation of cleaning dead corners at the contact point between the first rib 131 and the bottom 111 of the cleaning tank 11 and reducing the probability of dirt accumulating at the contact point between the first rib 131 and the bottom 111 of the cleaning tank 11.

[0057] Please refer to Figure 2 In some embodiments, the protrusion 13 further includes a plurality of protrusions 132 spaced apart along the extension direction of the water inlet 12, the protrusions 132 being located upstream of the water inlet 12 in the rotation direction of the cleaning component.

[0058] In the above embodiment, the protrusion 132 serves to scrub the cleaning component, so as to scrub out the dirt attached to the deeper parts of the cleaning component or scrub it to the surface of the cleaning component; and since the protrusion 132 is located upstream of the water inlet tank 12 in the rotation direction of the cleaning component, after the protrusion 132 scrubs out the dirt attached to the deeper parts of the cleaning component or scrubs it to the surface of the cleaning component, the dirt can be immediately scraped off by the scraping part 1311 on the first protruding rib 131 and the tank wall 121 of the water inlet tank 12, so as to reduce the probability of dirt falling onto the bottom 111 of the cleaning tank 11.

[0059] Furthermore, in the above embodiment, the multiple protrusions 132 are distributed at intervals along the extension direction of the water inlet groove 12, which can enhance the effect of the protrusions 132 in scrubbing and cleaning the parts.

[0060] Please refer to Figure 3 In some embodiments, the surface of the protrusion 132 facing the opening of the cleaning tank 11 is an arc surface that protrudes into the opening of the cleaning tank 11, so as to reduce the damage of the protrusion 132 to the cleaning parts.

[0061] Please refer to Figure 3 In some embodiments, the protrusion 13 further includes a second rib 133, which protrudes toward the opening of the cleaning tank 11 and is smoothly connected to the bottom 111 of the cleaning tank 11.

[0062] In the above embodiment, the second rib 133 can scrub the cleaning component to scrub out dirt that is attached to a deeper part of the cleaning component or scrub it to the surface of the cleaning component. In the subsequent process, the dirt is scraped off by the wall 121 of the water inlet tank 12 and falls into the water inlet tank 12, so as to more thoroughly clean the cleaning component and enhance the cleaning effect of the cleaning tray 1.

[0063] In the above embodiment, the second rib 133 protrudes into the opening of the cleaning tank 11, and the upper surface of the second rib 133 is a pressing arc surface 1331 protruding into the opening of the cleaning tank 11. The pressing arc surface 1331 is smoothly connected to the bottom 111 of the cleaning tank 11. On the one hand, this can reduce the damage of the second rib 133 to the cleaning parts, and on the other hand, it can prevent the formation of sharp corners at the contact point between the second rib 133 and the bottom of the cleaning tank 11, so as to prevent the formation of cleaning dead corners at the contact point between the second rib 133 and the bottom of the cleaning tank 11, and reduce the probability of dirt accumulating at the contact point between the second rib 133 and the bottom of the cleaning tank 11.

[0064] Please refer to Figure 1 In some embodiments, the cleaning tray 1 is also provided with a water outlet 14, the opening of the water outlet 14 is located at the bottom 111 of the cleaning tank 11, wherein the water inlet 12 is connected to the water outlet 14.

[0065] In the above embodiment, the outlet tank 14 can collect the water flow in the inlet tank 12 and the dirt carried by the water flow in the inlet tank 12, so as to facilitate the centralized treatment of dirt.

[0066] Please refer to Figure 1 In some embodiments, the cleaning tray 1 is also provided with a guide groove 15, which is connected to the cleaning tank 11 and the water outlet tank 14, and the bottom of the guide groove 15 is inclined from the water inlet tank 12 to the water outlet tank 14.

[0067] With the above settings, the guide channel 15 can guide the water flow in the inlet channel 12 to the outlet channel 14, which is more conducive to the water flow in the inlet channel 12 flowing into the outlet channel 14.

[0068] Please refer to Figure 1 In some embodiments, the cleaning tray 1 is provided with two cleaning tanks 11, which are located on both sides of the water outlet tank 14, and each cleaning tank 11 has a separate water inlet tank 12 at its bottom 111. The two water inlets 12 converge at the guide tank 15.

[0069] Please refer to Figure 5 The second aspect of this application provides a cleaning tray assembly, including the cleaning tray 1 described in the first aspect embodiment.

[0070] By applying the cleaning disc 1 of the first aspect embodiment to the cleaning disc assembly, when the cleaning component rotates relative to the cleaning disc assembly, the rotating cleaning component can contact and scrub the bottom of the cleaning tank 11 to transfer the dirt on the bottom of the cleaning tank 11 into the water inlet tank 12, thereby reducing the dirt remaining on the cleaning disc assembly.

[0071] Please refer to Figure 5In some embodiments, the cleaning tray assembly also includes a filter screen 2, which is located downstream of the water inlet tank 12 in the direction of water flow.

[0072] In the above embodiment, in the direction of water flow in the inlet tank 12, the filter screen 2 is located downstream of the inlet tank 12, so that dirt carried in the water flowing out of the inlet tank 12 can be collected on the filter screen 2 to prevent dirt from entering the water pump used in conjunction with the cleaning disc assembly, and to prevent the water pump from being blocked by dirt.

[0073] Please refer to Figure 5 In some embodiments, the filter screen 2 is disposed inside the water outlet tank 14.

[0074] A third aspect of this application provides a base station that includes the cleaning tray 1 of the first aspect embodiment, or the cleaning tray assembly of the second aspect embodiment.

[0075] By using the cleaning tray 1 of the first aspect embodiment described above, or by using the cleaning tray assembly of the second aspect embodiment described above, the residual dirt in the base station can be reduced.

[0076] It should be noted that the base station also includes a water supply component and a water pump. The outlet of the water supply component is connected to the inlet tank 12, and the water supply component is used to supply water to the inlet tank 12; the water pump is connected to the outlet tank 14, and the water pump is used to pump out the sewage in the outlet tank 14, and in the direction of sewage flow, the inlet of the water pump is located downstream of the filter screen 2.

[0077] The above embodiments are only used to illustrate the technical solutions of this application, and are not intended to limit them. Although this application has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some of the technical features.
