Description

Technical Field

[0001] This application relates to the field of cleaning product technology, and more particularly to a roller brush and cleaning equipment. Background Technology

[0002] Vacuum cleaners, floor scrubbers and other cleaning equipment are widely used for environmental cleaning in various indoor and outdoor scenarios. Different cleaning equipment can perform various functions such as vacuuming and mopping, thereby maintaining a clean and tidy living and working environment.

[0003] In related technologies, cleaning equipment with vacuuming and mopping functions generally cleans the floor by using a roller brush. The roller brush is equipped with a scraper. During cleaning, the roller brush rotates and drives the scraper to pat the floor. When the scraper comes into contact with the floor, it deforms and removes garbage or stains from the floor through friction, thus cleaning the floor.

[0004] However, existing squeegees have a short service life and are prone to damage after a period of use, resulting in reduced cleaning effect or loss of cleaning function. Utility Model Content

[0005] This application provides a roller brush and cleaning device to solve the technical problem that the current scraper has a short service life and is easily damaged after working for a period of time, resulting in weakened cleaning effect or loss of cleaning function.

[0006] In a first aspect, this application provides a roller brush for cleaning equipment, wherein the roller brush is rotatably mounted on the cleaning equipment; the roller brush includes a roller and a scraping element, the scraping element being connected to the roller.

[0007] The scraping component includes a support frame and a scraper body. The support frame is connected to the scraper body, and the hardness of the support frame is greater than that of the scraper body to support the scraper body. The scraper body is configured to contact and clean the surface to be cleaned when the cleaning equipment cleans the surface to be cleaned.

[0008] The roller brush provided in this application includes a roller and a scraper. The scraper is connected to the roller. During cleaning, the roller rotates, causing the scraper to slap the surface to be cleaned, thus cleaning the surface. The scraper includes a support frame and a scraper body. The scraper body has low hardness, allowing it to contact the surface to be cleaned and deform, removing debris or stains through friction. The support frame has high hardness, supporting the scraper body when the scraper slaps the surface, improving the overall structural strength and stability of the scraper, preventing damage, and extending its service life.

[0009] As an alternative implementation, along the radial direction of the roller, the edge of the scraper on the side opposite to the roller is higher than the edge of the support frame on the side opposite to the roller.

[0010] With this design, the scraper can make priority contact with the surface to be cleaned during cleaning, thus performing the cleaning function.

[0011] As an optional implementation, the support frame and the scraper are arranged side by side along a first direction; wherein the first direction forms an angle with the axial direction of the roller.

[0012] This design increases the overall thickness of the scraper without affecting its cleaning function, thereby improving structural strength and extending its service life.

[0013] As an alternative implementation, the support frame protrudes radially along the roller, and the scraper body is connected to the side of the support frame opposite to the roller.

[0014] This design improves the structural strength of the scraping components while reducing material usage and saving costs.

[0015] As an alternative implementation, the scraper and the support frame are integrally coated with rubber.

[0016] This design can improve the structural strength of the scraping parts and extend their service life.

[0017] As an optional implementation, along the radial direction of the roller, the scraper protrudes from the side of the roller away from the support frame by a height of h1, the support frame height is h2, and the ratio of h1 to h2 is 0.5-1.

[0018] This configuration, by controlling the ratio of h1 to h2 between 0.5 and 1, ensures that the scraper has appropriate flexibility during cleaning to guarantee the cleaning effect, while also improving overall strength to extend service life.

[0019] As an optional implementation, the ratio of the width of the scraper to the width of the support frame is 0.5-1, and the width direction of the scraper and the width direction of the support frame are the first direction.

[0020] This configuration ensures the overall strength of the scraper by controlling the ratio of the width of the scraper body to the width of the support frame between 0.5 and 1, while preventing excessive friction caused by an excessively wide scraper body.

[0021] As an optional implementation, the ratio of the volume of the scraper to the volume of the support frame is 0.5-1.

[0022] This configuration ensures the overall strength of the scraper by controlling the ratio of the volume of the scraper body to the volume of the support frame between 0.5 and 1, while reducing material usage and saving costs.

[0023] As an optional implementation, both the scraper and the support frame have polygonal cross-sections.

[0024] This design, with its polygonal shape, allows the force on the scraping body to be effectively transferred to the support frame through the edges and corners of the polygon, avoiding stress concentration and improving structural strength.

[0025] As an optional implementation, both the scraper and the support frame have quadrilateral cross sections.

[0026] This design, with its quadrilateral shape, enhances structural strength while facilitating manufacturing and assembly.

[0027] As an alternative implementation, the scraper extends along the axial direction of the roller; or, the scraper extends in a V-shape.

[0028] With this configuration, the scraper can clean along the axis of the roller, preventing any areas from being missed during cleaning.

[0029] As an alternative implementation, the roller includes a roller body and a connector. The connector is connected to the side of the roller body and has a through groove on the side of the connector away from the roller body. The scraper is at least partially inserted into the through groove so that the scraper is detachably connected to the roller.

[0030] The connector is arranged along the axial direction of the roller, and the through groove extends along the axial direction of the roller and matches the length of the connector.

[0031] The scraper has a connecting part configured to be inserted into a through groove so that the scraper is connected to the connecting part.

[0032] At least a portion of the support frame is located within the through slot and forms at least a portion of the connecting portion.

[0033] With this design, the connector and roller are detachably connected via a through slot, facilitating the replacement and disassembly of the scraping parts for cleaning.

[0034] As an alternative implementation, the roller, scraper, and support frame are integrally molded.

[0035] This design, through its one-piece molding, increases the structural strength of the roller brush and extends its service life.

[0036] As an optional implementation, both the scraper and the support frame are made of polymer materials.

[0037] This design strengthens the scraper and support frame with polymer materials, reducing the chance of damage to the scraper and support frame, thereby extending the service life of the scraper components.

[0038] As an optional implementation, the connector is provided with a plurality of through holes, which penetrate the connector in a first direction; the through holes are configured to form an airflow channel for airflow to pass through; wherein the first direction has an angle with the axial direction of the roller.

[0039] Multiple through holes are arranged along the extension direction of the connector, and the ratio of the area of ​​the through holes to the cross-sectional area of ​​the roller brush is 1%-99%.

[0040] This design increases the ventilation area through the through holes, improving cleaning efficiency while reducing the chance of hair getting tangled in the roller brush.

[0041] Secondly, this application provides a cleaning device, which includes a device body and the aforementioned roller brush, with the roller brush rotatably connected to the device body.

[0042] This application provides a roller brush and a cleaning device. The roller brush is applied to and rotatably connected to the cleaning device. The roller brush includes a roller and a scraper, with the scraper connected to the roller. The scraper includes a support frame and a scraper body, with the support frame connected to the scraper body. The support frame has a higher hardness than the scraper body to support the scraper body. The scraper body is configured to contact and clean the surface to be cleaned when the cleaning device cleans the surface. The roller brush provided by this application improves the structural strength and stability of the scraper, preventing damage to the scraper and extending its service life.

[0066] To make the objectives, technical solutions, and advantages of the embodiments of this application clearer, the technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, not all embodiments. Based on the embodiments of this application, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this application.

[0067] Vacuum cleaners, floor scrubbers and other cleaning equipment are widely used for environmental cleaning in various indoor and outdoor scenarios. Different cleaning equipment can perform various functions such as vacuuming and mopping, thereby maintaining a clean and tidy living and working environment.

[0068] In related technologies, cleaning equipment with vacuuming and mopping functions generally cleans the floor by using a roller brush. The roller brush is equipped with a scraper. During cleaning, the roller brush rotates and drives the scraper to pat the floor. When the scraper comes into contact with the floor, it deforms and removes garbage or stains from the floor through friction, thus cleaning the floor.

[0069] However, existing squeegees are generally made of flexible materials, which are prone to wear and tear or even damage during prolonged slapping of the floor, resulting in reduced cleaning effect or loss of cleaning function, short service life, and frequent replacement.

[0070] To address the aforementioned technical problems, this application provides a roller brush and cleaning equipment. The roller brush is applied to the cleaning equipment and includes a roller and a scraper. The scraper is connected to the roller. During cleaning, the roller rotates, causing the scraper to slap the surface to be cleaned, thus cleaning the surface. The scraper includes a support frame and a scraper body. The scraper body has low hardness, allowing it to contact and deform with the surface to be cleaned, removing debris or stains through friction. The support frame has high hardness, supporting the scraper body when the scraper slaps the surface, improving the overall structural strength and stability of the scraper, preventing damage, and extending its service life.

[0071] The following is an example illustrating the application scenarios of the roller brush and cleaning equipment provided in the embodiments of this application.

[0072] The roller brush provided in this application embodiment is used in cleaning equipment and is a cleaning structure in the cleaning equipment that comes into contact with the surface to be cleaned. The product type of the cleaning equipment in this application embodiment may include, but is not limited to, vacuum cleaners, floor scrubbers, and robotic vacuum cleaners. Depending on the product type, the cleaning equipment provided in this application embodiment can be used to clean various hard material types such as floor tiles and floors, and can be used to clean various soft material types such as carpets and sofas. This application embodiment does not make specific limitations in this regard.

[0074] Reference Figures 1 to 13 This application provides a roller brush 100 for use in a cleaning device 10. The roller brush 100 is rotatably mounted on the cleaning device 10. The roller brush 100 includes a roller 110 and a scraper 120, with the scraper 120 connected to the roller 110. The cleaning device 10 can move on the surface to be cleaned and clean it. The main body 200 of the cleaning device 10 may have a roller brush cavity 210, in which the roller brush 100 is rotatably mounted. The roller brush cavity 210 may have an air intake 220, which is connected to the suction unit through the suction channel 230 of the main body 200. During cleaning, the roller 110 rotates, causing the scraper 120 to slap the surface to be cleaned, removing dust, stains, and other debris. The suction unit is activated, causing the air intake 220 to generate negative pressure suction, drawing the debris into the waste collection device of the main body 200. The two work together to clean the surface.

[0075] As one possible implementation, the scraper 120 includes a support frame 121 and a scraper body 122. The support frame 121 is connected to the scraper body 122. The hardness of the support frame 121 is greater than the hardness of the scraper body 122 to support the scraper body 122. The scraper body 122 is configured to contact the surface to be cleaned and perform cleaning when the cleaning device 10 cleans the surface to be cleaned.

[0076] Understandably, the support frame 121 has a relatively high hardness, which can support the scraper body 122. Under the support of the support frame 121, the scraper body 122 can still achieve good dust removal and scraping effects even with relatively low hardness. For example, in order to ensure dust removal and scraping effects, the hardness of a traditional flexible scraper 120 is set to 50D. At this hardness, the scraper 120 will produce a lot of noise when it hits the surface to be cleaned. The scraper body 122 of the scraper 120 provided in this application can be set to 40D. Due to its softer texture, the scraper body 122 produces less noise when it hits the surface to be cleaned. Moreover, due to the support of the support frame 121, the scraper body 122 will not deform excessively, thus still achieving good dust removal and scraping effects. At the same time, because the scraper body 122 is softer, the scraper 120 as a whole is less likely to be damaged during the hitting process, thereby improving its service life.

[0077] It should be noted that when cleaning hard surfaces such as floors and tiles, the cleaning device 10 primarily relies on the scraper 122 to contact the surface. Supported by the support frame 121, the scraper 122 effectively removes dust and scrapes. However, when cleaning soft surfaces such as carpets and sofas, the scraper 122, being softer, can sink into the crevices of the surface. The support frame 121 then taps against the surface, dislodging deep-seated dust, hair, and other debris, making them easier to draw in through the air intake 220. Therefore, the roller brush 100 provided in this application has a cleaning effect on both hard and soft surfaces.

[0078] As one possible implementation, along the radial direction of the roller 110, the edge of the scraper 122 on the side opposite to the roller 110 is higher than the edge of the support frame 121 on the side opposite to the roller 110.

[0079] Understandably, in order for the scraper 122 to preferentially contact the surface to be cleaned, the farthest point of the scraper 122 relative to the roller 110 needs to be higher than the farthest point of the support frame 121 relative to the roller 110. At the same time, it is necessary to adjust the edge height of the scraper 122 and the support frame 121 so that when the scraper 120 is in its natural state, that is, when both the scraper 122 and the support frame 121 are in a free deformation state, the edge of the scraper 122 is higher than the edge of the roller of the cleaning device 10, and the edge of the support frame 121 is lower than the edge of the roller of the cleaning device 10. In this way, when the cleaning device 10 cleans a hard surface to be cleaned, only the scraper 122 contacts the surface to be cleaned, and the support frame 121 will not collide with the surface to be cleaned.

[0080] Reference Figures 3 to 5 , combined Figure 1 and Figure 2 In some embodiments, the support frame 121 and the scraper body 122 are arranged side by side along a first direction; wherein the first direction is at an angle to the axial direction of the roller 110.

[0081] It should be noted that the first direction refers to the width or thickness direction of the support frame 121 and the scraper body 122. This first direction can have a certain angle with the axial direction of the roller 110, greater than 0° and less than or equal to 90°. When the support frame 121 and the scraper body 122 are arranged side-by-side along the first direction, the edge of the scraper body 122 is still higher than the edge of the support frame 121. The support frame 121 is attached to one side of the scraper body 122 along the first direction. The support structure of the support frame 121 can be a single piece, such as... Figure 5 It can also be a structure consisting of multiple polygons or quadrilaterals, such as Figure 3 Along the axial direction of the roller 110, the support frame 121 matches the extension length of the scraper body 122 so that the scraper body 122 can be supported along the length direction.

[0082] Reference Figures 6 to 9 In other embodiments, the support frame 121 protrudes radially along the roller 110, and the scraper body 122 is connected to the side of the support frame 121 opposite to the roller 110.

[0083] In this embodiment, along the radial direction of the roller 110, the entire scraper body 122 is higher than the edge of the support frame 121, and the support structure of the support frame 121 can be a single integral structure. Along the first direction, the width of the scraper body 122 can be smaller than the width of the support frame 121, such as... Figure 8 and Figure 9 The width of the scraper 122 can also be equal to the width of the support frame 121, such as... Figure 6 and Figure 7 .

[0084] It should be noted that the scraper body 122 and the support frame 121 can be bonded together with adhesive, or they can be riveted or integrally coated with adhesive.

[0085] It should be noted that regardless of whether the scraper body 122 and the support frame 121 are arranged side by side along the first direction or side by side along the radial direction of the roller 110, the scraper body 122 will at least partially protrude from the edge of the support frame 121 along the radial direction of the roller 110. If the height of the scraper body 122 protruding from the side away from the roller 110 relative to the support frame 121 is h1, and the height of the support frame 121 is h2, then the ratio of h1 to h2 is 0.5-1.

[0086] Meanwhile, the ratio of the width of the scraper 122 to the width of the support frame 121 is 0.5-1, and the ratio of the volume of the scraper 122 to the volume of the support frame 121 is 0.5-1; wherein, the width direction of the scraper 122 and the width direction of the support frame 121 are the first direction.

[0087] Understandably, if the ratio is too small, when the roller 110 rotates, the support frame 121 mainly pats the surface to be cleaned. If the ratio is too large, the support frame 121 will have difficulty supporting the scraper 122. Since the scraper 122 is relatively soft, the friction between it and the surface to be cleaned is small after losing support, resulting in a smaller dust removal and scraping effect.

[0088] It is understandable that ensuring that the ratio of the protruding height, width, and volume of the scraper body 122 to the protruding height, width, and volume of the support frame 121 is within a certain range allows the support frame 121 to provide effective support for the scraper body 122, ensuring that the scraper part 120 has appropriate flexibility during cleaning while maintaining the cleaning effect, and also improving the overall strength to extend its service life.

[0089] It should be noted that the cross-sections of the scraper 122 and the support frame 121 can be polygonal. In this way, the force on the scraper 122 can be effectively transferred to the support frame 121 through the sides and corners of the polygon, avoiding stress concentration and improving structural strength.

[0090] In some embodiments, the cross-sections of the scraper 122 and the support frame 121 are both quadrilateral. The scraper 122 is a single quadrilateral structure, and the support frame 121 can be a single quadrilateral structure or multiple quadrilateral structures, which are spaced apart along the axial direction of the roller 110.

[0091] As one possible implementation, the scraper 120 extends along the axial direction of the roller 110; or, the scraper 120 extends in a V-shape.

[0092] It is understandable that the scraper 120 can extend in a straight line along the axial direction of the roller 110, which facilitates the mold making, processing and assembly of the scraper body 122 and the support frame 121; the scraper 120 can also extend in a V-shape along the axial direction of the roller 110, so that when the roller 110 rotates, when hair fibers, stains, etc. come into contact with the scraper 120, they will move towards the middle point of the V-shape as the roller 110 rotates, making it easier to be sucked in by the suction port 220 and improving cleaning efficiency.

[0093] Reference Figures 10 to 13 As one possible implementation, the roller 110 and the scraper 120 are detachably connected. The roller 110 includes a roller body 111 and a connector 112. The connector 112 is connected to the side of the roller body 111. The side of the connector 112 away from the roller body 111 has a through groove 1121. The scraper 120 is at least partially inserted into the through groove 1121 so that the scraper 120 can be connected to or disconnected from the roller 110.

[0094] The connector 112 is arranged along the axial direction of the roller 110, and the through groove 1121 extends along the axial direction of the roller 110 and matches the length of the connector 112; at the same time, the scraper 120 extends along the axial direction of the roller 110 and matches the length of the through groove 1121.

[0095] It should be noted that there can be multiple connectors 112 and multiple scraping parts 120, with each scraping part 120 and connector 112 connected in a one-to-one correspondence.

[0096] As one possible implementation, the scraper 120 has a connecting portion 123 configured to be inserted into the through groove 1121 so that the scraper 120 is connected to the connecting member 112; at least a portion of the support frame 121 is located in the through groove 1121 and forms at least a portion of the structure of the connecting portion 123.

[0097] It should be noted that when the scraper body 122 and the support frame 121 are arranged side by side along the first direction, both the scraper body 122 and the support frame 121 extend at least partially along the first direction and together form the connecting portion 123. When the scraper body 122 and the support frame 121 are arranged side by side along the radial direction of the roller 110, that is, when the scraper body 122 is located at the end of the support frame 121 away from the roller 110, the connecting portion 123 is formed by a portion of the structure of the support frame 121. The shape of the connecting portion 123 matches that of the through groove 1121. When the scraper part 120 is installed or removed, the connecting portion 123 is inserted into or pulled out from one end of the through groove 1121 to achieve the connection and removal of the scraper part 120 and the roller 110, which is convenient for operation. In addition, at least one end of the roller 110 may be provided with an end cap, which can be connected to the roller body 111 by means of buckles or the like, and prevent the connecting portion 123 from disengaging from the through groove 1121. In some embodiments, the through groove 1121 may also be provided on the roller 111 without the need for the connector 112, and the connecting part 123 may be inserted into the through groove 1121 and directly connected to the roller 111.

[0098] As one possible implementation, the roller 110, scraper 122, and support frame 121 can be integrally formed. The roller 110 may consist only of the roller body 111, with the roller body 111, scraper 122, and support frame 121 all integrally formed. Alternatively, the roller 110 may include the roller body 111 and a connector 112, with the roller body 111, connector 112, scraper 122, and support frame 121 all integrally formed. Because the scraper 120 has an increased service life and does not require frequent replacement, the integrally formed structure is more stable and has higher strength.

[0099] As one possible implementation, both the scraper body 122 and the support frame 121 are made of polymer materials. The materials of the scraper body 122 and the support frame 121 can be engineering plastics such as PP, PA nylon, and POM polyoxymethylene. Polymer materials can prevent rust, ensure structural strength, and are lighter than metal materials.

[0100] For example, the support frame 121 is made of polyoxymethylene, which has high rigidity and hardness and can provide strong support; the scraper body 122 is made of thermoplastic polyurethane elastomer, which has good elasticity and good wear resistance.

[0101] It should be noted that when the roller 110 is provided with a connector 112, the connector 112 may be provided with multiple through holes 1122, and the through holes 1122 penetrate the connector 112 in the first direction; the through holes 1122 are configured to form an airflow channel for airflow to pass through.

[0102] Understandably, after the connector 112 is provided with the through hole 1122, when the air intake 220 is suctioning, the airflow can pass through the periphery of the roller brush 100 on the one hand, and through the air path formed by the through hole 1122 on the other hand, which increases the ventilation area and thus increases the suction efficiency. At the same time, the through hole 1122 improves the airflow path in the suction cavity, which can prevent hair fibers from getting tangled on the roller brush 100.

[0103] Multiple through holes 1122 are arranged along the extension direction of the connector 112. The through holes 1122 can be circular, elliptical, or other shapes. The ratio of the area of ​​the through holes 1122 to the cross-sectional area of ​​the roller brush 100 is 1%-99%.

[0104] For example, the ratio of the area of ​​the through hole 1122 to the cross-sectional area of ​​the roller brush 100 can be 1%, 5%, 10%, 20%, 50%, 99%, etc., and this application embodiment does not make specific limitations.

[0105] This application provides a roller brush 100 and a cleaning device 10. The roller brush 100 is applied to and rotatably connected to the cleaning device 10. The roller brush 100 includes a roller 110 and a scraper 120, with the scraper 120 connected to the roller 110. The scraper 120 includes a support frame 121 and a scraper body 122, with the support frame 121 connected to the scraper body 122. The hardness of the support frame 121 is greater than the hardness of the scraper body 122 to support the scraper body 122. The scraper body 122 is configured to contact and clean the surface to be cleaned when the cleaning device 10 cleans the surface. The roller brush 100 provided by this application improves the structural strength and stability of the scraper 120, preventing damage to the scraper 120 and extending its service life.

[0106] Finally, it should be noted that 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 or all of the technical features therein.
