It should be understood that the described embodiments are only some of the embodiments of the present application, but not all the embodiments. Based on the embodiments in the present application, all other embodiments obtained by those skilled in the art without any creative effort fall within the scope of protection of the present application.
[0018] The embodiments of the present application provide a cleaning device, for example but not limited to a cleaning robot, a handheld cleaning device, etc., which will be mainly described below taking a cleaning robot as an example.
[0019] Please refer to Figure 1 and Figure 2 , Figure 1 is a structural schematic diagram of a cleaning device provided by some embodiments of the present application, Figure 2 is a three-dimensional structural schematic diagram of a cleaning device provided by some embodiments of the present application.
[0020] In some embodiments, the cleaning device 10 comprises a main body 100 and a cleaning member 200. The main body 100 can be the body of the cleaning device 10, and its specific structure can be set according to the specific type of the cleaning device 10, so as to meet the requirements of the specific type of the cleaning device 10. Figure 2The cleaning device 10 shown is an example. The bottom of the main body 100 can be provided with traveling wheels for driving the cleaning device 10 to travel on a working surface. The cleaning member 200 is movably connected to the main body 100 for cleaning the working surface. The cleaning member 200 is, for example, a mop that can be used to absorb liquid on the working surface, or can be used to absorb liquid from the main body 100 or an external base station, and absorb dirty substances on the working surface when in contact with the working surface, so as to achieve cleaning of the working surface. The liquid absorbed by the cleaning member 200 can be considered as sewage. Of course, the cleaning member 200 can also be other devices that can achieve similar cleaning functions.
[0021] The cleaning member 200 can be in the form of Figure 2 a roller and is rollingly connected to the main body 100. When the main body 100 travels in the forward direction X Figure 2 , the cleaning member 200 can be in contact with the working surface and rotate in the rotation direction Y Figure 2 to achieve cleaning of the working surface. The working surface is, for example but not limited to, a ground surface. It can be understood that the moving direction of the main body 100 on the working surface is, for example but not limited to, the forward direction X Figure 2 , which is only an example. In other embodiments, the cleaning member 200 can also be in other forms, and the way it is movably connected to the main body 100 can also be other ways. For example, the cleaning member 200 can be a disc mop, in the form of a disc, and can rotate relative to the main body 100 in a direction parallel to the bottom surface of the main body 100. For another example, the cleaning member 200 can be a track mop, in the form of a long strip, and can translate relative to the main body 100 in a direction parallel to the bottom surface of the main body 100.
[0022] The cleaning device 10 further comprises a transfer assembly 300 and a detection assembly 400. The transfer assembly 300 is in contact with the cleaning member 200 for transferring sewage on the cleaning member 200. It can be understood that the transfer assembly 300 transfers the sewage on the cleaning member 200 by physical contact, which is equivalent to cleaning the surface of the cleaning member 200. The detection assembly 400 is used to detect the sewage transferred by the transfer assembly 300. The cleaning device 10 can detect the degree of dirt of the sewage through the detection assembly 400, so as to execute a cleaning strategy accordingly. The detection assembly 400 can comprise a turbidity sensor for detecting the turbidity of the sewage.
[0023] The transfer assembly 300 can comprise a scraping member 310 that contacts the cleaning member 200 for scraping the sewage and dirty substances absorbed by the cleaning member 200 by scraping the surface of the cleaning member 200. The dirty substances are, for example, sludge. The scraping member 310 can be in the form of Figure 2The long strip shape can correspond to the length of the cleaning element 200 to increase the contact area between the scraping element 310 and the cleaning element 200 and improve the transfer efficiency of the scraping element 310 on the sewage on the surface of the cleaning element 200. The scraping element 310 can also have other shapes, such as a disc shape, a block shape, etc., and is not limited to the embodiment. In other embodiments, the transfer assembly 300 can also contact the cleaning element 200 through other structural elements to transfer the sewage on the cleaning element 200 in a manner other than scraping, such as extruding the sewage on the cleaning element 200.
[0024] The cleaning device 10 further includes a first container 500 and a second container 600. The first container 500 can be arranged on the main body 100 and used to store the sewage adsorbed by the cleaning element 200 during the cleaning process. The first container 500 can be a sewage tank used to provide the cleaning device 10 with a sewage storage capacity, so that the cleaning device 10 can store the sewage generated during the cleaning process by using the first container 500, and when the storage reaches a certain degree, return to the base station or other sewage treatment site to uniformly treat the sewage, without the need to frequently go back and forth between the working surface to be cleaned and the base station, which is beneficial to improve the continuous cleaning capacity of the cleaning device 10. Of course, the first container 500 can also have other shapes and is not limited to a sewage tank.
[0025] The second container 600 is arranged in the first container 500 and communicates with the first container 500. It can be understood that the volume of the second container 600 is smaller than that of the first container 500. The transfer assembly 300 is connected with the second container 600 and used to transfer the sewage on the cleaning element 200 to the second container 600, so that the sewage can be temporarily stored in the second container 600 and then flow out from the communication between the second container 600 and the first container 500 to be stored in the first container 500. The detection assembly 400 is used to detect the sewage in the second container 600. In other words, the object detected by the detection assembly 400 is the sewage temporarily stored in the second container 600.
[0026] It should be noted that the sewage is easy to mix with air and generate bubbles during the transfer from the cleaning element 200 to the first container 500, and these bubbles can interfere with the detection of the detection assembly 400 and may result in a low accuracy of the detection result. When the sewage is temporarily stored in the second container 600, the bubbles float on the liquid surface, so that the detection assembly 400 detects the sewage below the liquid surface, which can avoid the interference of the bubbles on the detection and is beneficial to improve the detection accuracy.
[0027] It can be understood that, since the detection assembly 400 needs to detect the sewage below the liquid level, the sewage needs to be accumulated in the container to a certain amount so that the liquid level reaches a certain height. If the cleaning device 10 detects the sewage stored in the first container 500 by using the detection assembly 400, on the one hand, in order to ensure the sewage storage capacity of the cleaning device 10, the volume of the first container 500 is usually large, so the time required for the sewage in the first container 500 to accumulate to a detectable degree will be relatively long, which will lead to low timeliness of detection, which is not conducive to the cleaning device 10 to execute the corresponding cleaning strategy in time according to the detection result; on the other hand, before the first container 500 is emptied, the cleaning device 10 can use the cleaning piece 200 to clean multiple times, and the sewage transferred to the first container 500 will mix together in different cleaning processes, so that the cleaning device 10 cannot accurately detect the current dirt degree of the cleaning piece 200.
[0028] The embodiment of the present application sets the second container 600 in the first container 500, and makes the transfer assembly 300 transfer the sewage on the cleaning piece 200 to the second container 600, so that the detection assembly 400 detects the sewage temporarily stored in the second container 600. Since the volume of the second container 600 is relatively small compared with the first container 500, the time required for the sewage in the second container 600 to accumulate to a detectable degree is relatively short, which can improve the detection timeliness of the cleaning device 10; on the other hand, by connecting the second container 600 with the first container 500, the sewage transferred to the second container 600 will continuously flow out and be stored in the first container 500, so that the sewage transferred to the second container 600 will not mix together in different cleaning processes, so that the cleaning device 10 can accurately detect the current dirt degree of the cleaning piece 200, and then accurately and timely execute the corresponding cleaning strategy according to the detection result.
[0029] In some application scenarios, when the detection result of the detection assembly 400 shows that the dirt degree of the cleaning piece 200 is within the first preset range, the cleaning device 10 can recognize that there are many dirty substances on the working surface at the moment, and the cleaning strategy executed by the cleaning device 10 at this moment can be repeated cleaning on the working surface at the moment.
[0030] In other application scenarios, when the detection result of the detection assembly 400 shows that the dirt degree of the cleaning piece 200 is within the second preset range, the cleaning device 10 can recognize that the dirt degree of the cleaning piece 200 at the moment is too high, which is not suitable for cleaning the working surface, and the cleaning strategy executed by the cleaning device 10 at this moment can be returning to the base station for deep cleaning.
[0031] It can be understood that the above cleaning strategies are only examples, and the cleaning strategy executed by the cleaning device 10 in the embodiment of the present application according to the detection result is, for example but not limited to, the above examples.
[0032] Please continue to see Figure 2 In some embodiments, the transferring assembly 300 can include a squeegee 310 and a sewage pipe 320. The squeegee 310 is disposed outside the first container 500 and in contact with the cleaning element 200. The sewage pipe 320 is disposed through the wall of the first container 500 and has one end disposed on the squeegee 310 and the other end disposed inside the first container 500 and in communication with the second container 600. The squeegee 310 can remove the sewage from the cleaning element 200 by scraping the surface of the cleaning element 200, and the sewage pipe 320 can transport the sewage removed by the squeegee 310 to the second container 600. The sewage pipe 320 can be sealingly connected to the wall of the first container 500.
[0033] The squeegee 310 can be disposed on the outer wall of the first container 500 and fixed to the main body 100 by the first container 500. The squeegee 310 can also be fixed to the main body 100 by other means, such as being directly disposed on the main body 100. The sewage pipe 320 can be fixedly connected to the squeegee 310 so as to be stably maintained at a position corresponding to the squeegee 310 during operation of the cleaning device 10. The sewage pipe 320 can also abut the surface of the squeegee 310 for contacting the sewage without being fixedly connected to the squeegee 310.
[0034] For example Figure 2 As shown, the squeegee 310 can be connected to the bottom end of the outer wall of the first container 500, and the sewage pipe 320 is disposed through the wall of the first container 500 and sealingly connected to the first container 500. By connecting the squeegee 310 and the sewage pipe 320 to the first container 500, the cleaning device 10 can maintain one end of the sewage pipe 320 at a position corresponding to the squeegee 310 at all times, so that the sewage pipe 320 can stably transfer the sewage scraped by the squeegee 310 to the second container 600. The squeegee 310 can be integrally formed with the first container 500.
[0035] Optionally, the squeegee 310 is provided with a water storage groove 301 in communication with the sewage pipe 320. The water storage groove 301 is disposed on the surface of the squeegee 310 for contacting the sewage. When the cleaning element 200 moves relative to the main body 100 to clean the working surface, the squeegee 310 can scrape the sewage on the cleaning element 200 and store it in the water storage groove 301. One end of the sewage pipe 320 can be located in the water storage groove 301 and in communication with the water storage groove 301, so as to transport the sewage stored in the water storage groove 301 to the second container 600.
[0036] The water storage groove 301 can be recessed from the surface of the squeegee 310 for contacting the sewage, for example Figure 2As shown, the surface of the dirt scraping member 310 can be arc-shaped to form the water storage groove 301. In other embodiments, the dirt scraping member 310 can also be designed in other shapes that can form the water storage groove 301, for example, the surface of the dirt scraping member 310 can be provided with a convex part, and the water storage groove 301 is formed by the convex part. The dirt scraping member 310 can also be designed in other structures that can scrape the dirt water from the cleaning member 200, for example, the surface of the dirt scraping member 310 used to contact the dirt water can be flat.
[0037] In some embodiments, the cleaning device 10 can include a suction pump 700 for providing power for the dirt water transfer assembly 300 to suck the dirt water. The suction pump 700 can be a vacuum pump, for example, a pneumatic vacuum pump, an electric vacuum pump, etc. The cleaning device 10 can also include a suction pipe 710 connected to the suction pump 700 and the first container 500 respectively, for forming negative pressure in the first container 500. When the negative pressure is formed in the first container 500, the pressure difference between the two ends of the dirt water pipe 320 inside and outside the first container 500 is formed, thereby generating the suction force for sucking the dirt water into the first container 500.
[0038] In other embodiments, the suction pump 700 can also provide power for the dirt water transfer assembly 300 to suck the dirt water in other ways. For example, the suction pump 700 can be directly connected to the first container 500, so as to form negative pressure in the first container 500; for another example, the suction pump 700 can be connected to the second container 600 through the suction pipe 710, and the end of the suction pipe 710 located in the first container 500 is also connected to the second container 600, so that the suction pump 700 can provide power for the dirt water transfer assembly 300 to suck the dirt water through the suction pipe 710 and the second container 600.
[0039] The cleaning device 10 can also provide power for the dirt water transfer assembly 300 to transfer the dirt water through structures other than the suction pump 700, for example, the cleaning device 10 can include a compression assembly for compressing the volume of the first container 500, for quickly reducing the volume of the first container 500 to reduce the gas pressure inside the first container 500 to form negative pressure; for another example, the cleaning device 10 can include a speed increasing assembly arranged in the first container 500, for increasing the flow speed of the fluid in the first container 500 to form negative pressure in the first container 500.
[0040] Please refer to Figure 2 and Figure 3 , Figure 3 are part structure schematic diagrams of the cleaning device provided by some embodiments of the present application.
[0041] In some embodiments, the second container 600 can be provided with a water inlet 601 at the top thereof. The water inlet 601 is in communication with the transfer assembly 300. The second container 600 can be provided with a water outlet 602 at the bottom thereof, which is in communication with the first container 500. The sewage in the second container 600 can flow out through the water outlet 602 and be stored in the first container 500. The water inlet 601 can be larger than the water outlet 602.
[0042] The transfer assembly 300 can be partially suspended above the top of the second container 600 and in communication with the water inlet 601, for example. Figure 2 As shown, one end of the sewage pipe 320 located in the first container 500 can extend above the second container 600, and the opening of the sewage pipe 320 can be opposite to the water inlet 601. The transfer assembly 300 can also be partially located inside the second container 600, for example, one end of the sewage pipe 320 located in the first container 500 can be inserted into the water inlet 601.
[0043] As described above, in order to achieve detection, the second container 600 needs to temporarily accumulate a certain amount of sewage during the sewage transfer process. Therefore, the flow rate of the sewage flowing into the second container 600 needs to be greater than the flow rate of the sewage flowing out of the second container 600. The present application can make the upper limit of the sewage receiving capacity of the second container 600 greater than the upper limit of the sewage discharge capacity by designing the water inlet 601 to be larger than the water outlet 602. Thus, the cleaning device 10 can adjust the transfer efficiency of the transfer assembly 300 to sewage, so that the sewage can be temporarily stored in the second container 600 during the transfer process, thereby facilitating the detection of the detection assembly 400.
[0044] In other embodiments, the sewage pipe 320 can also be sealingly connected to the second container 600. In this case, the water inlet 601 of the second container 600 does not need to be larger than the water outlet 602. The second container 600 can be provided with other through holes as air holes to make the sewage entering rate of the second container 600 greater than the sewage discharging rate, so as to avoid the detection assembly 400 from being unable to detect the sewage in the second container 600. The second container 600 can also not be provided with air holes. The cleaning device 10 can control the suction force of the suction pump 700 to control the flow rate of the sewage in the second container 600.
[0045] In some embodiments, the inner surface of the second container 600 includes a flow guide slope 610 located between the top and the bottom of the second container 600, which is used to guide the sewage in the second container 600 to the water outlet 602.
[0046] In some application scenarios, the cleaning device 10 can be cleaned at different time periods respectively. During the first cleaning, the sewage can be transferred from the cleaning member 200 to the first container 500 and temporarily stored in the second container 600 for detection by the detection assembly 400. Understandably, if there is more sewage remaining in the second container 600 during the first cleaning and cannot be discharged, the remaining sewage will mix with the new sewage during the second cleaning, resulting in inaccurate detection results of the detection assembly 400 during the second cleaning.
[0047] The embodiment of the present application designs the inner surface of the second container 600 to include a guide slope 610, so that the sewage can be discharged through the water outlet 602 as much as possible under the guidance of the guide slope 610, so as to reduce or even eliminate the sewage remaining in the second container 600. The guide slope 610 can be the inner surface of the side of the second container 600.
[0048] Alternatively, the second container 600 can be a funnel, which has the characteristics of a large top opening, a small bottom opening, and a sloping side. The top opening can be used as the water inlet 601, the bottom opening can be used as the water outlet 602, and the side slope can be used as the guide slope 610. The volume of the upper half of the second container 600 is smaller than the volume of the lower half. The sewage can flow into the second container 600 from the water inlet 601 and flow out of the water outlet 602 at a slower speed than when it flows in, thereby at least temporarily accumulating sewage in the lower half for detection by the detection assembly 400. In other embodiments, the second container 600 can also have other shapes, such as a cylindrical shape.
[0049] It can be understood that all directional indications (such as up, down, left, right, front, back, etc.) in the embodiments of the present application are only used to explain the relative positional relationship, movement condition, etc. between components in a certain posture (as shown in the drawings), and if the certain posture changes, the directional indications will also change accordingly.
[0050] In some embodiments, the detection assembly 400 can include at least one photoelectric sensor 410. The photoelectric sensor 410 can be located outside the second container 600 and used to emit detection light that can penetrate the wall of the second container 600. The second container 600 is made of a light-transmitting material. The detection assembly 400 can use the detection light emitted thereby to detect the degree of dirt of the sewage in the second container 600, for example, the turbidity of the sewage. The detection assembly 400 can also include other structural members, such as a circuit board, which can be used to analyze the detection results of the sensor.
[0051] The detection assembly 400 can include at least two photoelectric sensors 410. As shown in FIG. 4, the two photoelectric sensors 410 can be arranged on the same side of the second container 600. Figure 3As shown, the at least two photoelectric sensors 410 include a light emitter 411 and a light receiver 412. The light emitter 411 is configured to emit detection light, and the light receiver 412 is configured to receive reflected light. The light emitter 411 and the light receiver 412 are both arranged outside the second container 600, and are arranged on opposite sides of the second container 600, respectively. In other embodiments, the detection assembly 400 can also include only one photoelectric sensor 410, which can emit detection light and receive reflected light.
[0052] It should be understood that the terminology used herein in the specification and the appended claims is for the purpose of describing particular embodiments only and is not intended to be limiting thereof. As used in this specification and the appended claims, the singular forms "a," "an" and "the" are intended to include the plural forms as well, unless the context clearly indicates otherwise. Also, the term "first," "second," and the like used in the description and the appended claims is merely used for distinguishing between similar elements and does not necessarily imply a sequence or order unless explicitly stated otherwise. As such, these terms are used interchangeably and do not imply a serial or chronological order amongst elements unless explicitly stated otherwise. Furthermore, the terms "comprise," "have" and "include" and the like as used herein are used in the sense of "open ended" and do not exclude additional elements or steps.
[0053] In other embodiments, the detection assembly 400 can also include a sensor arranged inside the second container 600, which can detect the dirtiness of the sewage by contacting the sewage. The specific type of sensor included in the detection assembly 400 can be selected according to the content to be detected. Hereinafter, the detection assembly 400 is taken as an example in which the photoelectric sensor 410 is included.
[0054] Optionally, the photoelectric sensor 410 is arranged outside the first container 500, and the detection light emitted by the photoelectric sensor 410 can also pass through the wall of the first container 500. The first container 500 and the second container 600 are both made of light-transmissive material. The detection light emitted by the photoelectric sensor 410 can pass through the wall of the first container 500 and the wall of the second container 600 in sequence, so as to detect the sewage in the second container 600. The embodiments of the present application can avoid the photoelectric sensor 410 from contacting the sewage in the first container 500, so as to prevent the photoelectric sensor 410 from being damaged. In other embodiments, the photoelectric sensor 410 can also be arranged on the inner wall of the first container 500, or arranged on the outer wall of the second container 600. In this case, the detection light only needs to pass through the wall of the second container 600.
[0055] The detection assembly 400 can be fixed to the main body 100, and the first container 500 can be detachably connected with the main body 100, so that the first container 500 can be separated from the main body 100 and the detection assembly 400. After cleaning is completed or the amount of sewage stored in the first container 500 reaches a certain amount, the user can detach the first container 500 from the main body 100, so as to facilitate the discharge of the sewage in the first container 500 and the cleaning of the first container 500. The photoelectric sensor 410 of the detection assembly 400 can abut against the outer wall of the first container 500, so as to improve the detection efficiency. In other embodiments, the detection assembly 400 can also be fixed to the outer wall of the first container 500.
[0056] The first container 500 can have a split structure. The user can detach the first container 500, so as to facilitate the discharge of the sewage and the cleaning of the inner wall of the first container 500. The first container 500 can also have an integrated structure and be provided with a sewage discharge port for discharging the sewage. It can be understood that the sewage discharge port is in a blocked state during cleaning.
[0057] The second container 600 can be fixed to the first container 500, for example, integrally formed with the first container 500, so as to not only prevent the relative position of the second container 600 and the first container 500 from changing during cleaning and interfering with detection, but also enable the second container 600 to be installed or detached together with the first container 500, facilitating cleaning and discharge of the sewage.
[0058] In summary, the cleaning device 10 provided by the embodiments of the present application can clean the working surface by using the cleaning piece 200, and transfer the sewage on the cleaning piece 200 by using the transfer assembly 300, so as to clean the cleaning piece 200. In addition, by cooperation of the transfer assembly 300, the detection assembly 400, the first container 500 and the second container 600, real-time detection of the sewage transferred by the transfer assembly 300 can be realized, so that the cleaning device 10 can detect the degree of dirt of the cleaning piece 200 in real time, and execute corresponding cleaning strategies based on the detection result, which is beneficial to improving the timeliness and accuracy of the cleaning device 10 when the cleaning strategies are taken.
[0059] It should be understood that the terms "comprising" and "having" and any variations thereof used in the present application and the appended claims are intended to cover non-exclusive inclusion.
