[0044] The terms "first", "second", "third" (if any) in the specification and claims of the present application and the above drawings are used to distinguish similar objects, and do not necessarily describe a specific order or sequence. It should be understood that the data thus used can be interchanged under appropriate circumstances, so that the embodiments of the present application described herein can be implemented in an order other than those illustrated or described herein.

[0045] Moreover, the terms "comprising" and "having" and any variations thereof are intended to cover a non-exclusive inclusion, for example, a process, method, system, product or maintenance tool including a series of steps or units not necessarily limited to those explicitly listed, but can include other steps or units not explicitly listed or inherent to such processes, methods, products or maintenance tools.

[0046] In order to make the purposes, technical solutions and advantages of the embodiments of the present application clearer, the technical solutions in the embodiments of the present application will be described clearly and completely below with reference to the drawings in the embodiments of the present application. Obviously, the described embodiments are only some of the embodiments of the present application, rather than all the embodiments. Based on the embodiments in the present application, all other embodiments obtained by a person of ordinary skill in the art without creative work fall within the protection scope of the present application.

[0047] Cleaning equipment with dust collection and mopping functions usually uses a floor brush to clean the floor, the floor brush is provided with a roller brush and a water tank, the water tank can supply cleaning water to wet the roller brush, and the wet roller brush rolls on the floor to achieve the effect of wet mopping. The floor brush is usually also provided with a suction port, which can suck up garbage and debris on the floor and sewage scraped off the roller brush.

[0048] However, in the current cleaning equipment, the roller brush on the floor brush is usually wrapped with a cleaning component such as a mop that is easy to absorb water. During cleaning, the cleaning component is pressed by a scraping strip to scrape off the absorbed sewage, but the water cannot be completely scraped off. After cleaning is completed, there will be water stains left on the roller brush, and if the cleaning component on the roller brush is not removed and dried in time, the floor brush is easy to produce odor or even mold. Therefore, the current cleaning equipment needs to be placed separately on a matching drying base station for drying after cleaning to avoid odor of the mop. For example, the cleaning equipment is provided with a cleaning base station with drying function, which washes the roller brush and then dries the mop on the roller brush.

[0049] However, the cleaning equipment needs to use a drying device to dry the mop on the roller brush after cleaning, which wastes time and power resources, is time-consuming and labor-intensive, and on the other hand, the placement of the matching drying device occupies additional space and has high cost.

[0050] In order to solve the above technical problems, the embodiments of the present application provide a roller brush assembly and a cleaning equipment. The cleaning equipment uses the design of the cleaning structure on the surface of the roller brush to form a ventilation groove with the surface protruding scraping part. The scraping part scrapes the dirt on the floor, and the sewage and particles can be sucked into the interior of the cleaning equipment through the ventilation groove. There is no need to set a water-absorbing mop or other wrapping component on the roller brush, and thus there is no need to set a separate drying device to dry the roller brush, which saves time and labor, saves family space and reduces product cost.

[0051] The following is an example illustrating the application scenarios of the roller brush assembly and cleaning equipment provided in the embodiments of this application.

[0052] The roller brush assembly provided in this application embodiment is used in cleaning equipment. The cleaning equipment is a cleaning tool with a roller brush structure. Specifically, the product type of the cleaning equipment in this application embodiment may include, but is not limited to, vacuum cleaners, floor scrubbers, sweeping machines, and robotic vacuum cleaners. Depending on the product type, the cleaning equipment provided in this application embodiment can be used to clean floors, wooden floors, marble floors, glass floors, etc. This application embodiment does not make any specific limitations on this.

[0053] Figure 1 A cross-sectional view of the location of the roller brush in the cleaning device provided in an embodiment of this application; Figure 2 This is a schematic diagram of the structure of the roller brush in the cleaning equipment provided in the embodiments of this application; Figure 3 for Figure 2 A partial view of position A in the middle; Figure 4 This is a cross-sectional view of the roller brush in the cleaning equipment provided in the embodiments of this application; Figure 5 This is an end view of the roller brush in the cleaning device provided in an embodiment of this application.

[0054] See Figures 1 to 5 As shown, this application embodiment provides a roller brush assembly 100, which is applied in a cleaning device 10. When the cleaning device 10 cleans the ground, the roller brush can contact the ground, and as the cleaning device 10 moves, the roller brush rolls and rubs the ground to clean the dust and stubborn stains attached to the ground.

[0055] The roller brush assembly 100 provided in this application embodiment includes a roller body 110 and a roller brush shaft 120. The roller body 110 is coaxially connected to the outside of the roller brush shaft 120. The surface of the roller body 110 is provided with a plurality of scraping portions 130, which are spaced apart along the axial direction of the roller body 110, and ventilation grooves 101 are formed between adjacent scraping portions 130.

[0056] Understandably, when the roller brush assembly 100 contacts and rubs against the ground, the scraping part 130 abuts and rubs against the ground. The scraping part 130 can increase the friction between the roller brush assembly 100 and the ground, resulting in a better stain removal effect. The cleaning device 10 is equipped with a suction assembly 500, which can create negative pressure to suck stains and particulate debris into the cleaning device 10. When the roller brush assembly 100 rotates to clean, the negative pressure airflow generated by the suction assembly 500 can flow through the ventilation slot 101. The wastewater and particulate debris carried by the roller brush assembly 100 scraping the ground can flow through the ventilation slot 101 and be sucked into the cleaning device 10 with the airflow.

[0057] In some embodiments, the ventilation groove 101 extends along the circumference of the rolling body 110. When the rolling body 110 rotates, the scraping portions 130 on both sides of the ventilation groove 101 can cover the area passed by the ventilation groove 101, so that the ground area facing the ventilation groove 101 can be scraped by the scraping portions 130 as the rolling brush assembly 100 rotates, thereby avoiding water stains.

[0058] It can be understood that the ventilation groove 101 is arranged around the circumference of the rolling body 110 in a ring shape. The scraping portions 130 arranged around the circumference of the rolling body 110 can also be in a ring shape, and the ventilation groove 101 in a ring shape is formed between two adjacent scraping portions 130.

[0059] For example, the rolling brush assembly 100 can be arranged along the width direction of the cleaning device 10, and when the cleaning device 10 moves forward and backward for cleaning, the rotation axis of the rolling brush assembly 100 is perpendicular to the moving direction of the cleaning device 10. The rolling brush assembly 100 rotates around its own axis. The edge profile of the scraping portion 130 can be a three-dimensional curve, that is, the edge profile of the scraping portion 130 is not located in a plane perpendicular to the axis direction of the rolling brush assembly 100, so that when the rolling brush assembly 100 rotates, the scraping portion 130 can scrape and clean the ground area corresponding to the ventilation groove 101.

[0060] It should be noted that in the rolling brush assembly 100 provided by the embodiments of the present application, the scraping portions 130 can rub the ground to clean it, and the ventilation groove 101 between the scraping portions 130 allows airflow to pass through, so that sewage and small and large particle impurities can be sucked away through the ventilation groove 101. With the rotation of the rolling brush assembly 100, the scraping portion 130 will scrape the ground area corresponding to the ventilation groove 101, thereby avoiding water stains. In this way, while having good cleaning effect, the rolling brush assembly 100 does not need to be separately wrapped with a mop on the outer surface, and after cleaning is completed, the rolling brush is in a relatively dry state and does not need to be separately dried, nor will it produce an odor.

[0061] For example, the rolling body 110 can be made of soft rubber material at least on the surface. During the cleaning of the ground, the rolling brush assembly 100 can lift stains and particle impurities by friction, and can also adhere the stains to the surface. The stains will not be sucked into the deep interior of the rolling body 110 from the surface of the rolling body 110, and therefore, the stains and particle impurities lifted by the rolling brush assembly 100 can be completely removed by the negative pressure suction force on the cleaning device 10 and the centrifugal force of the rolling body 110.

[0062] Since the dirt adheres to the surface of the roller body 110 without infiltrating into the interior of the roller body 110, the surface of the roller body 110 can be cleaned by rotation and scraping of the roller brush assembly 100, and the roller brush assembly 100 does not need to be dried after cleaning, which saves time and effort, does not need to be equipped with a separate drying device, does not occupy additional space, and reduces product cost.

[0063] Please continue to refer to Figures 1 to 5 In some embodiments, the roller brush shaft 120 can be rotationally coupled with the device body 200. The roller brush assembly 100 has a cylindrical structure as a whole, and the rotation axis of the roller brush assembly 100 relative to the mounting structure of the cleaning device 10 can be approximately the axis of the roller brush assembly 100.

[0064] In some embodiments, the scraping portion 130 is an integral molded part with the roller body 110, and the roller body 110 and the scraping portion 130 can be elastically deformed when the roller brush assembly 100 contacts the surface to be cleaned. The scraping portion 130 extrudes and rubs the ground, which more easily removes dirt and thus improves the cleaning effect.

[0065] For example, the roller body 110 can be made of soft rubber material, including but not limited to PVC (polyvinyl chloride), PE (polyethylene), or other soft plastic materials with elasticity, or the roller body 110 can be made of rubber, silicone, etc., and the embodiments of the present application do not make specific limitations in this regard.

[0066] In some embodiments, the side edges of the ventilation groove 101 are different from the roller body 110 axial end in at least part of the extension direction. In this way, the ventilation groove 101 forms a special-shaped ring structure around the circumferential side of the roller body 110, and the ground position corresponding to the ventilation groove 101 changes along the axial direction of the roller brush assembly 100 as the roller brush assembly 100 rotates.

[0067] It can be understood that, during rotation of the roller brush assembly 100, the ground position corresponding to the ventilation groove 101 changes along the axial direction of the roller brush assembly 100, that is, different circumferential positions of the ventilation groove 101 correspond to different ground areas as the roller brush assembly 100 rotates. Correspondingly, the scraping portion 130 can scrape water stains at different axial positions of the roller body 110 to avoid water stains remaining at the position of the ventilation groove 101.

[0068] In addition, the cross-sectional shape of the ventilation groove 101 can be square, triangular, semicircular, etc. For example, the groove bottom and two side walls of the ventilation groove 101 can be in contact with the particulate impurities on three sides, which increases the contact area during cleaning and more easily lifts the particulate impurities, which are then sucked into the interior of the cleaning device 10.

[0069] In some embodiments, the maximum distance between different positions of the side edge of the ventilation groove 101 in the axial direction of the roller body 110 is W1, and the width of the ventilation groove 101 is W2; wherein W1≥W2. In this way, during the rotation of the roller brush assembly 100, the wiping area of the scraping part 130 can cover the area passed by the ventilation groove 101.

[0070] It can be understood that, in the axial direction of the roller body 110, with reference to the end of the roller body 110, the side edge of the ventilation groove 101 at different positions in the axial direction is close to or far from the end of the roller body 110, wherein the distance difference between the closest point and the farthest point in the axial direction of the roller body 110 is W1. The value of W1 is greater than or equal to the width W2 of the ventilation groove 101, so that during one rotation of the roller brush assembly 100, the ground area passed by the ventilation groove 101 can be wiped by the scraping part 130.

[0071] In some embodiments, the projection of the scraping part 130 in the radial direction of the roller body 110 at least protrudes to one end of the axial direction of the roller body 110, so as to increase the area of the ground wiped by the scraping part 130. The cleaning device 10 can suck stains and particulate impurities through the ventilation groove 101, so as to ensure a relatively high cleaning efficiency and avoid water stains.

[0072] For example, the widths of the scraping part 130 at different positions along the extension direction thereof are equal. This can ensure uniform wiping of the ground during one rotation of the roller brush assembly 100, and avoid water stains.

[0073] For example, the widths of the ventilation groove 101 at different positions along the extension direction thereof are equal, so as to maintain the consistency of the ventilation cross-sectional size of the ventilation groove 101 during the rotation of the roller brush assembly 100, thereby improving the ventilation smoothness of the ventilation groove 101 during the rotation of the roller brush assembly 100.

[0074] In some embodiments, the surface of the scraping part 130 is provided with a plurality of protruding parts 140, and the plurality of protruding parts 140 are arranged at intervals along the extension direction of the scraping part 130. The protruding part 140 is arranged in a protruding manner away from the center of the roller body 110 at the top of the scraping part 130.

[0075] It can be understood that, when the roller brush assembly 100 is in contact with the ground, the protruding part 140 can be in contact with the ground and press the scraping part 130, so that the protruding part 140 can increase the friction between the scraping part 130 and the ground, remove stubborn stains on the ground, and improve the cleaning effect.

[0076] In some embodiments, the protruding parts 140 on adjacent scraping parts 130 are arranged at intervals in the circumferential direction of the roller body 110. In this way, with the rotation of the roller brush, the protruding part 140 can wipe the ground at a high frequency, and has a better stain cleaning effect.

[0077] For example, along the axial direction of the roller body 110, the lines connecting the corresponding protruding portions 140 between the plurality of scraping portions 130 arranged in sequence can be convex, concave or undulating arc lines or broken lines, so that the protruding portions 140 are in contact with the ground for most of the time or the entire process during one rotation of the roller brush assembly 100.

[0078] In some embodiments, the plurality of scraping portions 130 can be arranged in sequence from one end of the axial direction of the roller body 110 to the other end of the axial direction of the roller body 110. The outer side edges of the scraping portions 130 located at the ends of the roller body 110 are arranged flush with the ends of the roller body 110. In this way, the cleaning area of the scraping portions 130 can cover different positions in the axial direction of the roller body 110, expanding the cleaning range.

[0079] It can be understood that the profile lines of the inner sides of the two scraping portions 130 located at the two ends of the roller body 110 are three-dimensional curves, and the profile lines of the outer sides are circular and parallel to the end faces of the roller body 110.

[0080] It should be noted that the specific width values of the scraping portions 130 and the number of the scraping portions 130 are not limited in the embodiments of the present application.

[0081] Figure 6 A schematic diagram of a dirt suction path in a cleaning device provided by the embodiments of the present application is shown.

[0082] Please refer to Figure 6 , and in combination with Figure 1 , the embodiments of the present application provide a cleaning device 10, which comprises a device body 200 and the roller brush assembly 100 in the above technical solution, and the roller brush assembly 100 is rotationally arranged in the device body 200. The device body 200 is the main structure of the cleaning device 10, and the device body 200 can move on the ground when the cleaning device 10 cleans the ground. For example, when the cleaning device 10 is a scrubber, the device body 200 can be the scrubber brush.

[0083] Among them, the device body 200 has a roller brush cavity 201, and the roller brush cavity 201 has an opening 202 facing downward of the device body 200. The roller brush assembly 100 is rotationally arranged in the roller brush cavity 201, and part of the structure of the roller brush assembly 100 protrudes from the opening 202 to the lower side of the device body 200, so as to be in contact with the ground when cleaning the ground.

[0084] In some embodiments, the cleaning device 10 further comprises a scraping member 300. The scraping member 300 is arranged on the device body 200. The scraping member 300 is arranged at the edge of the opening 202. When the cleaning device 10 cleans the ground, the scraping member 300 can scrape the ground to remove stubborn stains on the ground. In addition, the scraping member 300 can cooperate with the roller brush to scrape and collect water stains and particulate impurities on the ground, so as to facilitate the device body 200 to suck the dirty water and particulate impurities into the interior of the cleaning device 10.

[0085] The cleaning device 10 provided by the embodiments of the present application further comprises a water spraying assembly 400 and a dirty water suction assembly 500. The water spraying assembly 400 is arranged on the device body 200 and is configured to spray water to at least one of the roller brush and the surface to be cleaned below the device body 200. The dirty water suction assembly 500 is arranged on the device body 200 and is used to suck the dirty water and particulate impurities generated during cleaning into the interior of the cleaning device 10.

[0086] The device body 200 is provided with a water collecting groove 203, which is arranged at least partially around the roller brush cavity 201. The dirty water suction assembly 500 has a dirty water suction port 501, which is in communication with the water collecting groove 203. The dirty water scraped by the rotation of the roller brush can enter the water collecting groove 203, and the dirty water suction assembly 500 can suck the dirty water in the water collecting groove 203 away.

[0087] It can be understood that the water spraying assembly 400 can spray cleaning water to the surface of the roller brush, and the cleaning water can be brought to the ground by the roller brush to wet the ground. Alternatively, the water sprayed by the water spraying assembly 400 can naturally flow to the ground. When the roller brush rotates and contacts and rubs the wet ground, it can remove stubborn stains attached to the ground. The stains generated after the ground is wetted can be attached to the surface of the roller brush, and the stains attached to the surface of the roller brush can be separated from the roller brush and enter the water collecting groove 203 under the action of centrifugal force as the roller brush rotates. The dirty water suction assembly 500 can suck the dirty water in the water collecting groove 203 into the interior of the device body 200 through the dirty water suction port 501. In this way, the stains generated after the ground is wetted will not be sucked into the roller brush and cannot be squeezed out, and after the cleaning is completed, the roller brush is in a relatively dry state and does not need to be dried separately, and no odor is generated.

[0088] In some embodiments, the water spraying assembly 400 can comprise a spray head, which is located at the rear side of the roller brush cavity 201 along the cleaning direction of the cleaning device 10 and opposite to the roller brush. In this way, the ground can be wetted more efficiently when the roller brush advances to clean.

[0089] It can be understood that the spray head can extend along the axial direction of the rolling brush, the length of the spray head can match the length of the rolling brush, and a plurality of water spray holes can be arranged on the side of the spray head facing the rolling brush. The plurality of water spray holes can be arranged at intervals along the length direction of the spray head. In this way, different positions of the axial length of the rolling brush can be wetted, and accordingly, the area passed by the rolling brush can be uniformly wetted, achieving good washing effect.

[0090] For example, the device body 200 can be provided with a clean water tank and a water pump. The water inlet of the clean water tank and the water pump is communicated, and the water outlet of the water pump can be communicated with the spray head. The cleaning tank can supply water to the spray head through the water pump, and the cleaning water sprayed by the spray head has a certain water pressure.

[0091] It should be noted that since the main body of the rolling brush can be made of soft rubber material, sewage will not be sucked into the deep interior of the rolling brush, but will only adhere to the surface of the rolling brush. Therefore, after cleaning is completed, the rolling brush surface can be self-cleaned by spraying cleaning water with a certain water pressure on the rolling brush surface through the water spraying device and cooperating with the rolling brush rotation. After self-cleaning is completed, the rolling brush surface is relatively dry, and does not need to be dried by a drying device, nor will it produce odor.

[0092] In some embodiments, the sewage suction assembly 500 can include a sewage tank 510, an air pump 520, and a sewage suction pipe 530. The sewage suction pipe 530 is communicated with the water collecting groove 203 and forms a sewage suction port 501. The sewage tank 510 is communicated with the sewage suction pipe 530. The air pump 520 is communicated with the sewage tank 510. The air pump 520 is configured to draw air from the sewage tank 510 to generate suction force at the sewage suction port 501.

[0093] It can be understood that the sewage tank 510 and the air pump 520 can be arranged on the device body 200. The air pump 520 draws air from the sewage tank 510 to generate negative pressure in the sewage tank 510, and then the sewage suction pipe 530 forms an air flow from the sewage suction port 501 to the sewage tank 510. The sewage suction port 501 forms suction force due to negative pressure, which can quickly suck the sewage in the water collecting groove 203 into the sewage tank 510, avoiding sewage overflow in the water collecting groove 203 during cleaning.

[0094] It should be noted that the sewage suction port 501 can not only suck the sewage in the water collecting groove 203, but also directly suck the particulate impurities brought by the rolling brush through negative pressure suction. Alternatively, the sewage suction port 501 separately sucks the sewage in the water collecting groove 203, and another suction port is additionally arranged on the rear side of the rolling brush cavity 201 along the cleaning direction of the cleaning device 10 to suck the impurities, so as to realize the shunting of impurities and water stains.

[0095] The embodiment of the present application provides a rolling brush assembly and a cleaning device, wherein the rolling brush assembly comprises a rolling body and a rolling brush shaft, the rolling body is coaxially connected to the outer side of the rolling brush shaft; the surface of the rolling body is provided with a plurality of scraping parts, the plurality of scraping parts are arranged at intervals along the axial direction of the rolling body; and a ventilation groove is formed between adjacent scraping parts. The ventilation groove extends along the circumferential direction of the rolling body; when the rolling body rotates, the scraping parts on both sides of the ventilation groove can cover the area passed by the ventilation groove. In the cleaning process, the large and small particle impurities can be sucked away through the ventilation groove, and with the rotation of the rolling brush assembly, the scraping parts can scrape the ground area corresponding to the ventilation groove, so that water stains are avoided to be left, the rolling brush assembly does not need to be separately wrapped with a mop on the outer surface, therefore, after the cleaning is completed, the rolling brush assembly does not need to be dried, time and labor are saved, space is saved, and cost is reduced.

[0096] Finally, it should be noted that: the above embodiments are only used to illustrate the technical solutions of the present application, and not to limit them; although the present application has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that: it can still modify the technical solutions recorded in the foregoing embodiments, or make equivalent replacement for part or all of the technical features; and these modifications or replacements do not make the essence of the corresponding technical solutions deviate from the scope of the technical solutions of the embodiments of the present application.
