Description

Technical Field

[0001] This application relates to the field of cleaning equipment technology, and more particularly to a cleaning component, a cleaning robot, and a cleaning system. Background Technology

[0002] Cleaning equipment is developing rapidly and is gradually replacing manual cleaning, becoming an indispensable cleaning helper for many households, such as cleaning robots and floor scrubbers. In related technologies, when cleaning equipment mops or wipes the floor, some debris or impurities will adhere to the rollers. With prolonged use, this debris can easily become entangled on the rollers or clog the wastewater tank, affecting the normal operation of the cleaning equipment. Utility Model Content

[0003] This application provides a cleaning component, a cleaning robot, and a cleaning system that can separate garbage and impurities on a roller using a scraper and reduce the entanglement of garbage.

[0004] In a first aspect, embodiments of this application provide a cleaning component, including: support; A roller, rotatably connected to the bracket, is used to clean the surface to be cleaned, and the roller has a first direction of rotation; A wastewater recovery assembly is disposed on the support in the first rotational direction of the drum, and the wastewater recovery assembly is used to recover at least a portion of the wastewater on the drum; A waste recycling assembly is disposed on the support, the waste recycling assembly including a scraper, the scraper being pivotally disposed on the support for pivotally contacting the circumferential side of the roller to scrape off at least a portion of the waste on the roller; In the first rotational direction of the roller, the scraper is located upstream of the wastewater recycling assembly.

[0005] Secondly, embodiments of this application also provide a cleaning robot, including a main body and cleaning components as described in the above embodiments.

[0006] Thirdly, embodiments of this application also provide a cleaning system, including a cleaning base station and a cleaning robot as described in the above embodiments.

[0007] Based on the cleaning components, cleaning robot, and cleaning system in this application embodiment, this embodiment achieves the separation of garbage and sewage on the roller by setting a reciprocating oscillating scraper on the support. At the same time, because the scraper is always in a reciprocating oscillating state, it can promptly scrape off the garbage adhering to the roller, avoiding the garbage adhesion affecting the cleaning effect of the roller, and reducing the probability of garbage getting tangled on the scraper. In addition, in the first rotation direction of the roller, the scraper is located upstream of the sewage recovery component. Therefore, when the roller rotates, garbage and impurities will be scraped off by the scraper first, reducing the situation of garbage getting tangled on the roller. This prevents garbage from accumulating at the scraper when it is scraped off along with sewage, affecting the sewage scraping effect, thereby reducing the probability of garbage clogging at the sewage recovery component and helping to ensure the smooth rotation of the roller.

[0011] To more clearly illustrate the technical solutions in the embodiments of this application or related technologies, a clear and complete description will be provided below with reference to the accompanying drawings in the embodiments of this application. Obviously, the described embodiments are only some embodiments of this application, and not all embodiments. Based on the embodiments in this application, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the scope of protection of this application.

[0012] In related technologies, when cleaning equipment performs tasks such as mopping and wiping the floor, debris or impurities can adhere to the rollers. Over time, this debris can easily become entangled on the rollers or clog the wastewater tank, affecting the normal operation of the cleaning equipment. Additionally, in some cleaning equipment, the debris on the rollers can be filtered through the wastewater tank. However, with prolonged use, the wastewater tank is prone to clogging, also impacting the normal operation of the cleaning equipment.

[0013] Regarding the above situation, firstly, please refer to [link / reference needed]. Figures 1-2 This application proposes a cleaning component (not shown in the figure) for use in a cleaning robot 200. The cleaning component includes a support 10, a roller 20, a waste collection component 30, and a wastewater collection component 50.

[0014] The roller 20 is rotatably connected to the support 10 for cleaning the surface to be cleaned. The roller 20 has a first rotation direction. The wastewater recovery assembly 50 is disposed on the support 10. In the first rotation direction of the roller 20, the wastewater recovery assembly 50 is used to recover at least a portion of the wastewater on the roller 20. The waste collection assembly 30 is disposed on the support 10. The waste collection assembly 30 includes a scraper 31. The scraper 31 is oscillatingly disposed on the support 10 for oscillating contact with the peripheral side of the roller 20 to scrape off at least a portion of the waste on the roller 20. In the first rotation direction of the roller 20, the scraper 31 is disposed upstream of the wastewater recovery assembly 50.

[0015] Specifically, the roller 20 is used to clean garbage and impurities from the surface to be cleaned. The garbage collection assembly 30 may also include a garbage collection trough 32, which is used to collect the garbage and impurities scraped off the roller 20 by the scraper 31. The scraper 31 can reciprocate relative to the support 10, thereby scraping off and separating the garbage and impurities on the roller 20 and guiding them into the garbage collection trough 32, improving the efficiency of garbage collection. The movable connection between the scraper 31 and the support 10 can be a sliding connection or a rotating connection.

[0016] It should be noted that the reciprocating oscillating design of the scraper 31 can reduce the risk of debris entanglement, thereby ensuring the continuous and efficient operation of the cleaning components. Specifically, in this embodiment, by setting the reciprocating oscillating scraper 31 on the bracket 10, the separation of debris and impurities on the roller 20 is achieved. At the same time, because the scraper 31 is always in a reciprocating oscillating state, it can promptly scrape off the debris adhering to the roller 20, avoiding the debris adhesion affecting the cleaning effect of the roller 20, and reducing the probability of debris entanglement on the scraper 31. In addition, in the first rotation direction of the roller 20, the scraper 31 is located upstream of the sewage recovery component 50. Therefore, when the roller 20 is rotating, the debris and impurities will be scraped off by the scraper 31 into the debris recovery trough 32 first, reducing the situation of debris entanglement on the roller 20. This prevents the debris from accumulating at the scraper 51 when it is scraped off along with the sewage, affecting the sewage scraping effect, and thus reducing the probability of debris clogging at the sewage recovery component 50, which is conducive to ensuring the smooth rotation of the roller 20.

[0017] It should also be noted that the waste collection trough 32 has a first opening 321 facing the scraper 31 and the roller 20. The first opening 321 of the waste collection trough 32 extends along the axis of the roller 20, and the length of the first opening 321 along the axis of the roller 20 is greater than or equal to the length of the roller 20 along the axis of the roller 20. This ensures that waste and impurities can smoothly enter the waste collection trough 32 during the rotation of the roller 20, reducing waste overflow. The first opening 321 of the waste collection trough 32 is directly facing the scraper 31 and the roller 20, so that waste and impurities falling from the roller 20 can fall directly into the waste collection trough 32 through the first opening 321. The impurities scraped off the roller 20 by the scraper 31 are also effectively guided into the waste collection trough 32 by the reciprocating swing of the scraper 31. This allows the waste and impurities carried on the roller 20 to be quickly and efficiently separated and collected into the waste collection trough 32 without going through a complex waste channel structure, thus simplifying the internal structure of the cleaning components. In addition, the waste recycling bin 32 and the bracket 10 are detachably connected, which makes it convenient for users to clean and maintain quickly.

[0018] In some embodiments, in the first rotation direction of the roller 20, the waste collection trough 32 is located upstream of the scraper 31. That is, when the roller 20 rotates, it first contacts the ground, then rotates to a position opposite to the waste collection trough 32, and then rotates to a position contacting the scraper 31. For example, taking the roller 20 having a first contact portion on its circumferential side, when the cleaning assembly is cleaning the ground, the first contact portion on the roller 20 first contacts the ground, and then rotates to a position opposite to the waste collection trough 32. At this time, some heavier waste adhering to the first contact portion will fall into the waste collection trough 32 under gravity, while some lighter impurities will still adhere to the first contact portion. Then, the first contact portion rotates to a position contacting the scraper 31, at which point the scraper 31 begins to swing back and forth, separating some lighter impurities from the roller 20 and guiding them into the waste collection trough 32. This reduces the amount of waste and impurities on the first contact portion entangled on the roller 20, preventing secondary pollution of the ground and improving the cleaning effect.

[0019] In some embodiments of this application, the scraper 31 is oscillatingly mounted on the support 10 via a crank-rocker mechanism, meaning that the scraper 31 and the support 10 are rotatably connected. The structure and principle of the crank-rocker mechanism have been disclosed in related technologies and will not be elaborated here.

[0020] It should be noted that, compared to the solution where the scraper 31 is fixed to the bracket 10 via a fixed structure, the scraper 31 in this application contacts the roller 20 via a swinging motion, which achieves a better scraping effect and reduces deformation caused by the scraper 31 being fixed to the bracket 10 and in contact with the roller 20 for a long time. Furthermore, the swinging path of the scraper 31 has an upper stop point and a lower stop point, and the movement space of the swinging scraper 31 is limited between the upper stop point and the lower stop point. Compared to the solution where the scraper 31 is 360° rotated and connected to the bracket 10, the scraper 31 in this application requires relatively less movement space. In addition, the scraper 31 in this application can avoid the rotating scraper from carrying garbage to various places inside the machine body when rotating 360°, which would cause the garbage pollution area to spread. The rotating scraper is prone to causing dirt inside the machine body, which could lead to equipment failure or additional cleaning burden for the user. Therefore, it can be seen that compared with the structure of the rotating scraper, the oscillating scraper 31 of this application has better garbage control capability. During the operation, the scraper 31 only needs to oscillate within a limited oscillation range (between the upper and lower dead points). It can oscillate within the preset space to scrape off garbage on the surface of the roller, and can also avoid the problem of internal pollution of the machine body caused by excessive rotation of the scraper 31.

[0021] Please continue reading Figures 1-3In some embodiments of this application, the cleaning component further includes a water component 60, which is disposed on the bracket 10. The water component 60 has a water outlet 611 on the side facing the roller 20, which is used to discharge water to the peripheral side of the roller 20.

[0022] Specifically, the water purification component 60 includes a water tank 61, with water outlets 611 disposed on the water tank 61. The water tank 61 is positioned above the roller 20 so that when the roller 20 rotates, water in the water tank 61 drips evenly onto the surface of the roller 20 through the water outlets 611, ensuring that the roller 20 remains constantly moist and enhancing the cleaning effect. Multiple water outlets 611 can be provided on the water tank 61 to ensure that clean water drips evenly onto the circumferential surface of the roller 20. The diameter of the water outlets 611 can be set according to actual conditions to control the water flow, ensuring that the surface of the roller 20 is moist without excessive water accumulation, further optimizing the cleaning effect and improving the overall cleaning performance of the cleaning component.

[0023] In this process, in the first rotational direction of the roller 20, the clean water assembly 60 is located downstream of the wastewater recovery assembly. As the cleaning robot 100 moves forward, the roller 20 rolls along with it. The roller 20 first contacts the surface to be cleaned and cleans it. Simultaneously, as the roller 20 continues to roll, the scraper 31 swings and contacts the roller 20, scraping away the solid waste and impurities adhering to the surface of the roller 20 into the waste collection tank 32. Subsequently, the scraper squeezes out the wastewater absorbed in the roller 20, which is then collected by the wastewater recovery tank 52. Then, the water outlet 611 on the clean water tank 61 drips water onto the roller 20, continuously wetting the surface of the roller 20 to facilitate its continued cleaning of the surface. In this process, solid impurities on the roller 20 are effectively separated from liquid wastewater, reducing the amount of impurities entering the wastewater recovery tank 52 and thus lowering the risk of clogging in the wastewater recovery tank 52.

[0024] In some embodiments, the wastewater recovery assembly 50 further includes a first pump and a wastewater tank 53. The first pump connects the wastewater recovery tank 52 and the wastewater tank 53, pumping wastewater from the wastewater recovery tank 52 to the wastewater tank 53 for centralized storage and treatment, preventing secondary pollution and further optimizing the cleaning effect. Additionally, the wastewater tank 53 is equipped with a water level sensor to monitor the wastewater volume in real time, promptly reminding the user to clean it and ensuring the continuous and efficient operation of the cleaning assembly.

[0025] The water purification component 60 also includes a second water pump and a water purification tank 62. The second water pump connects the water purification tank 61 and the water purification trough 62, and pumps water from the water purification tank 62 to the water purification tank 61 to ensure a continuous supply of clean water. Meanwhile, the water purification tank 62 is equipped with a water level sensor to monitor the water level in real time, promptly reminding the user to add water and ensuring the continuous and efficient operation of the cleaning component.

[0026] In summary, such as Figures 1-2 As shown, the separate design of the clean water tank 62 and the wastewater tank 53 can effectively prevent cross-contamination and improve cleaning quality. In addition, the independent structure of the clean water tank 62 and the wastewater tank 53 also facilitates separate maintenance and management. During operation, the cleaning components can coordinate the work of each component through an intelligent control system to ensure that the dripping of clean water and the collection of wastewater are synchronized, maximizing cleaning efficiency.

[0027] Furthermore, the water purification assembly 60 includes a pressure plate (not shown in the figure), which is located downstream of the water outlet 611 in the first rotation direction of the roller 20 and is interference-fitted with the circumferential side of the roller 20.

[0028] Specifically, there is a slight contact pressure between the pressure plate and the outer peripheral surface of the roller 20. Since the pressure plate is located downstream of the water outlet 611, when water drips from the water outlet 611 onto the surface of the roller 20, the pressure plate can promptly press the surface of the roller 20, causing water to penetrate from the surface of the roller 20 into the roller, thereby ensuring that the deeper parts of the roller 20 can also be fully wetted, which is beneficial to enhancing the cleaning effect of the roller 20 on the surface to be cleaned. At the same time, the pressure plate can also effectively prevent the water dripping from the water outlet 611 onto the surface of the roller 20 from splashing due to the high-speed rotation of the roller 20.

[0029] In some embodiments of this application, the oscillation path of the scraper 31 has an upper stop point and a lower stop point. In the first rotation direction of the roller 20, the upper stop point of the scraper 31 is located downstream of the lower stop point, and the oscillation angle between the upper stop point and the lower stop point of the scraper 31 is less than or equal to 30°.

[0030] It is understood that the scraper 31 has a connecting end 31 and a free end 32. The connecting end 31 of the scraper 31 is rotatably connected to the bracket 10 via a rotating shaft, and the free end 32 contacts the circumferential side of the roller 20. The connecting end 31 reciprocates relative to the bracket 10. At this time, the swing axis of the scraper 31 is the axis of the rotating shaft. For example, taking the direction perpendicular to the rotating shaft and the rotation axis of the roller 20 as the reference direction, the scraper 31 can rotate 30° around the axis above the reference direction to reach the upper dead point, and the scraper 31 can also rotate 30° around the axis below the reference direction to reach the lower dead point. The scraper 31 reciprocates within this range, thus forming a complete reciprocating swing cycle.

[0031] Specifically, the minimum distance between the scraper 31 and the rotation axis of the roller 20 at least at the top and bottom dead centers is less than or equal to the radius of the roller 20. It can be understood that when the scraper 31 swings to the top or bottom dead center, it is in its extreme position. At this point, the distance between the scraper 31 and the axis of rotation of the roller 20 is less than or equal to the radius of the roller 20. In other words, the scraper 31 remains in contact with the surface of the roller 20 throughout its swing, thus preventing debris from passing through the gap between the scraper 31 and the roller 20 and ensuring that as much debris and impurities as possible are separated from the roller 20.

[0032] Specifically, in the swing trajectory of the scraper 31, the movement trajectory of the free end 32 of the scraper 31 coincides with part of the circumferential side of the roller 20. That is to say, the free end 32 of the scraper 31 is in contact with the circumferential side of the roller 20 during the movement, so that the free end 32 is always in contact with the surface of the roller 20 during the movement, preventing garbage from passing through the gap between the free end 32 of the scraper 31 and the roller 20, ensuring that the garbage and impurities on the roller 20 are completely separated, further reducing the situation of garbage entangled on the roller 20, and helping to ensure the smooth rotation of the roller 20.

[0033] The free end 32 of the scraper 31 abuts against the circumferential side of the roller 20. That is, the free end 32 of the scraper 31 is in close contact with the circumferential side of the roller 20 to form a seamless connection. This ensures that most of the small impurities on the circumferential side of the roller 20 cannot escape the scraping of the free end 32 during the oscillation of the scraper 31, and are effectively guided into the garbage recycling bin 32. This greatly reduces the secondary pollution of the ground caused by impurities entangled on the roller 20, and improves cleaning efficiency.

[0034] In some embodiments of this application, the angular velocity of the scraping member 31 from the lower dead point to the upper dead point is less than the angular velocity of the roller 20. Here, angular velocity represents the arc distance traveled by an object per unit time. The greater the angular velocity, the greater the angle the object rotates per unit time, and the faster the rotation speed.

[0035] Specifically, the oscillation frequency of the scraper 31 from the lower stop point to the upper stop point is lower than the rotation frequency of the drum 20, so that as much garbage as possible on the circumference of the drum 20 can be scraped into the garbage recycling trough 32 by the scraper 31 during the rotation of the drum 20.

[0036] It is understandable that the scraper 31 can contact the circumferential side of the roller 20 multiple times within one rotation of the roller 20 to further optimize the garbage separation effect and improve the cleaning effect. The high-frequency reciprocating oscillation of the scraper 31 can not only enhance the separation effect of garbage on the roller 20, but also reduce the entanglement of garbage on the scraper 31, thereby preventing the scraper 31 from getting stuck due to garbage entanglement.

[0037] In some embodiments, the scraper 31 rotates and swings relative to the bracket 10. The swing axis of the scraper 31 is parallel to the rotation axis of the roller 20. The connecting end 31 of the scraper 31 is rotatably connected to the bracket 10 through a rotating shaft. Therefore, the swing axis of the scraper 31 is the axis of the rotating shaft, which helps to increase the contact area between the scraper 31 and the peripheral side of the roller 20.

[0038] For example, the length of the scraper 31 along the rotation axis of the roller 20 is greater than or equal to the length of the roller 20 along the axis of the roller 20, so as to ensure that the scraper 31 can effectively contact the circumferential side of the roller 20 throughout the entire length of the roller 20, thereby completely removing impurities from the circumferential side of the roller 20. In addition, the length setting of the scraper 31 also takes into account the synchronization with the roller 20, avoiding cleaning dead corners on the roller 20 due to insufficient length of the scraper 31, and further improving the overall cleaning effect of the cleaning assembly.

[0039] In some embodiments of this application, the waste recycling assembly 30 further includes a waste recycling trough 32. On a projection plane parallel to the surface to be cleaned, at least a portion of the orthographic projection of the scraper 31 overlaps with the orthographic projection of the waste recycling trough 32. That is, in a direction perpendicular to the surface to be cleaned, the scraper 31 is located above the waste recycling trough 32, thereby allowing as much waste as possible scraped off from the roller 20 by the scraper 31 to fall into the waste recycling trough 32 under the action of gravity, thereby improving the waste recycling efficiency.

[0040] Please see Figure 2 In some embodiments of this application, the outer peripheral side of the roller 20 is at least partially composed of an absorbent sponge 21. It is easy to understand that the absorbent sponge 21 has a strong water absorption capacity, which can not only quickly absorb sewage on the ground and prevent sewage from spreading during the cleaning process, but also reduce the risk of water dripping from the roller 20. The surrounding arrangement of the absorbent sponge 21 also allows the roller 20 to continuously absorb sewage when it rotates.

[0041] Meanwhile, the soft texture of the absorbent sponge 21 is more friendly to the ground material and is less likely to cause scratches, ensuring that the cleaning process is both efficient and safe. In addition, as the scraper 31 swings back and forth, it can come into contact with the absorbent sponge 21 on the side of the roller 20, thereby separating the solid and liquid on the roller 20 and further improving the cleaning efficiency.

[0042] Alternatively, in some embodiments, at least one end of the scraper 31 that contacts the roller 20 is an elastic structure or a bristle structure. This facilitates the deformation of the scraper 31, enabling it to effectively scrape away fine impurities and debris when in contact with the circumferential side of the roller 20, avoiding potential damage to the circumferential side of the roller 20 caused by a hard scraper. Simultaneously, the elastic or bristle structure can buffer the friction between the scraper 31 and the roller 20 to a certain extent, extending the service life of both the scraper 31 and the roller 20, ensuring a long-term stable cleaning effect. The design of the elastic or bristle structure not only improves cleaning efficiency but also reduces maintenance costs. Furthermore, the flexibility of the elastic or bristle structure allows the scraper 31 to better adapt to the subtle changes in the circumferential side of the roller 20 during reciprocating oscillations.

[0043] In some embodiments, the wastewater recovery assembly 50 includes a scraper 51 for interference fit with the outer peripheral surface of the roller 20 to scrape off at least a portion of the wastewater on the roller 20.

[0044] Specifically, there is interference between the wiper blade 51 and the roller 20, resulting in a contact force between them, which squeezes out the wastewater on the roller 20. The wastewater recovery assembly 50 also includes a wastewater recovery tank 52 for collecting at least a portion of the wastewater scraped off the roller 20 by the scraper blade 51. The scraper blade 51 can squeeze the wastewater off the roller 20 so that the wastewater flows into the wastewater recovery tank 52. In the first rotational direction of the roller 20, the scraper element 31 is disposed upstream of the scraper blade 51.

[0045] For example, when the roller 20 rotates, it first contacts the ground and then rotates to a position where it contacts the scraper 31. The scraper 31 can scrape solid impurities on the roller 20 into the waste collection trough 32. Subsequently, the roller 20 continues to rotate to the squeegee 51. Due to the abutting force between the squeegee 51 and the roller 20, the squeegee 51 can effectively squeeze out the sewage on the surface of the roller 20. The squeezed-out sewage is collected by the sewage collection trough 52, thereby achieving the purpose of solid-liquid separation of impurities and sewage on the roller 20. This reduces the risk of impurities entering the sewage collection trough 52 and clogging it, ensuring the unobstructed flow of the sewage collection trough 52 and improving cleaning efficiency. It can be understood that during this process, the roller 20 is in a continuous rotation state or a step-by-step rotation state.

[0046] Wherein, the distance between an end of the water scraping plate 51 in contact with the drum 20 and the axis of the drum 20 is defined as a, and the distance between an end of the scraping member 31 in contact with the drum 20 and the axis of the drum 20 is defined as b, wherein a < b. It can be understood that both the water scraping plate 51 and the scraping member 31 serve as abutting members that abut against the outer peripheral surface of the drum 20. The smaller the shortest distance between the axis of the drum 20 and the abutting member, the greater the degree of interference between the abutting member and the drum 20. An increased degree of interference leads to an increase in the pressure exerted by the abutting member on the surface of the drum 20. Since the scraping member 31 is configured to scrape off garbage on the surface of the drum 20, while the water scraping plate 51 is configured to scrape sewage off the drum 20, the abutting pressure between the scraping member 31 and the drum 20 needs to be smaller than that between the water scraping plate 51 and the drum 20. Therefore, a should be greater than b, so as to ensure that the scraping member 31 can contact the drum 20 to scrape off the garbage on the surface of the drum 20, and will not excessively interfere with the surface of the drum 20 to cause sewage to be scraped out by the scraping member 31.

[0047] Please refer to Figures 2-3 , in some embodiments of the present application, the cleaning assembly further comprises a guide member 70, one end of the guide member 70 is connected to the garbage recovery tank 32, and the other end of the guide member 70 extends toward the direction of the drum 20. In the first rotation direction of the drum 20, the guide member 70 is arranged upstream of the scraping member 31.

[0048] Specifically, a sewage inlet 11 is formed between the garbage recovery tank 32 and the drum 20. When the cleaning robot 100 moves forward, the guide member 70 can guide garbage and impurities on the ground, so that the garbage and impurities move to the sewage inlet 11 along the inclined slope of the guide member 70, thereby smoothly entering the garbage recovery tank 32 and improving the dust collection efficiency of the cleaning robot 100. Since the guide member 70 is arranged upstream of the scraping member 31, the guide member 70 can initially guide part of the garbage on the surface to be cleaned into the garbage recovery tank 32, thereby preliminarily reducing the amount of garbage adhered to the drum 20. Then the drum 20 continues to rotate, and the garbage on the drum 20 is scraped into the garbage recovery tank 32 by the scraping member 31. Wherein, the guide member 70 can be made of soft rubber material, so that it can better fit the ground during movement and reduce the frictional resistance between the guide member 70 and the ground.

[0049] In a second aspect, please refer to Figures 4-5 , the present application provides a cleaning robot 100, comprising a main body 90, an air-drying assembly (not shown in the figures) and the cleaning assembly according to any one of the above embodiments. Wherein, the cleaning assembly is arranged on the main body 90, the air-drying assembly can also be arranged on the main body 90, the garbage recovery tank 32 comprises an air inlet and an air outlet, and the air-drying assembly is configured to form an air flow channel in the garbage recovery tank 32 through the air inlet and the air outlet, so as to air-dry the garbage in the garbage recovery tank 32.

[0050] It is understandable that the garbage recycling bin 32 can collect the garbage on the roller 20. When the garbage in the garbage recycling bin 32 is wet garbage, an airflow channel can be formed through the drying component, so that the air in the garbage recycling bin 32 can flow and generate a corresponding airflow, thereby drying the wet garbage in the garbage recycling bin 32 and avoiding the growth of bacteria and odors.

[0051] In some embodiments, such as Figure 5 As shown, the cleaning robot 100 also includes a drive wheel 80 located at the bottom of the main body 90. The drive wheel 80 is rotatably connected to the main body 90, and the rotation direction of the drive wheel 80 is the same as that of the roller 20, thereby reducing the risk of slippage of the cleaning robot 100 during operation and improving the stability and movement efficiency of the robot.

[0052] Thirdly, this application proposes a cleaning system, including a cleaning base station (not shown in the figure) and a cleaning robot 200 as described in the above embodiments, wherein the cleaning robot 200 is used to interface with the cleaning base station.

[0053] In some embodiments, such as Figure 3 and Figure 4 As shown, the garbage recycling bin 32 is also equipped with a dust outlet 322, and the bracket 10 is equipped with a collection port 12 that communicates with the dust outlet 322.
