Description

Technical Field

[0001] This application relates to the field of cleaning product technology, and in particular to a floor brush device and cleaning equipment. Background Technology

[0002] Vacuum cleaners, floor scrubbers and other cleaning equipment are widely used for cleaning in various indoor and outdoor environments. These cleaning devices can scrape the floor with a roller brush and suck up debris through the air vent to clean the floor.

[0003] In related technologies, cleaning equipment includes a roller brush and a scraper. The roller brush has a cloth on its surface that can roll up garbage, debris, and water stains on the ground, while the scraper can remove the garbage, debris, and water stains stuck to the cloth, thus ensuring the continuous cleaning function of the roller brush.

[0004] However, existing scraper strips are made of hard materials, which can easily cause wear to the roller cloth, or existing scraper strips are designed as floating structures, but the structure is more complex. Utility Model Content

[0005] This application provides a floor brush device and cleaning equipment to solve the technical problems of existing scraper blades being made of hard material, which easily causes wear to the roller cloth, or existing scraper blades being designed as floating structures, which are relatively complex.

[0006] In a first aspect, this application provides a floor brush device, including a device body, a roller, and a scraper. The roller is rotatably connected to the device body, and the scraper is connected to the device body. The scraper contacts the roller to scrape the roller. At least a portion of the scraper is a soft structure so that the scraper can be bent when scraping the roller.

[0007] The floor brush device provided in this application includes a roller and a scraper. When the roller rotates, it can scrape the surface to be cleaned and pick up debris and water stains. During the cleaning process, the scraper can scrape the roller to prevent debris and dirt adhering to the roller surface from affecting the normal cleaning function of the roller. The scraper has a simple structure. By making part of the structure a soft structure, the scraper can bend when scraping the roller, thus having a certain floating space, thereby preventing the scraper from causing wear to the roller.

[0008] As an optional implementation, the scraping component includes a pressure block and a scraper. The scraper includes a scraper body and a scraping part. The scraping part is connected to the scraper body and contacts the roller to scrape the roller. The pressure block is disposed on the upper side of the scraper body and fixes the scraper body.

[0009] This setup, by fixing the scraper body with pressure blocks, can prevent excessive deformation of the scraping parts from affecting the scraping effect.

[0010] As an alternative implementation, one of the scraper body and the scraping part is a soft structure, and the other is a hard structure.

[0011] This design ensures the effective scraping action of the scraping component while allowing the scraping section to bend.

[0012] As an optional implementation, both the scraper body and the scraping part are made of soft material.

[0013] This design prevents the rigid structure from causing wear on the rollers.

[0014] As an alternative implementation, the roller extends along the width direction of the device body; the scraper extends along the length direction of the roller, and the length of the scraper matches the length of the roller.

[0015] This design ensures that all parts of the roller along its length can contact the scraping parts, preventing any missed areas.

[0016] As an optional implementation, the scraping section includes a multi-segment scraping structure, which is arranged sequentially at intervals along the length of the roller, and the length of the scraping section matches the length of the roller.

[0017] This design, with its multi-segment scraping structure, ensures that different areas of the scraping section do not interfere with each other.

[0018] As an alternative implementation, the scraping part is an integral structure, and the length of the scraping part matches the length of the roller.

[0019] This design, by making the scraping part an integral structure, facilitates the production and installation of the scraping part.

[0020] As an alternative implementation, the scraping part has a bending angle relative to the scraper body.

[0021] This design, by bending the scraping part so that it is tangent to the roller at the contact point, improves the scraping effect.

[0022] As an alternative implementation, the compact is a rigid structure.

[0023] This design improves the fixing effect of the pressure block on the scraper body.

[0024] Secondly, this application provides a cleaning device, which includes the aforementioned floor brush device.

[0025] This application provides a floor brush device and cleaning equipment. The floor brush device includes a main body, a roller, and a scraper. The roller is rotatably connected to the main body, and the scraper is connected to the main body, contacting the roller to scrape it. At least a portion of the scraper is a flexible structure, allowing it to bend when scraping the roller. The scraper of this application has a simple structure and a flexible feature, allowing it to float according to different forces when scraping the roller, ensuring effective scraping while avoiding wear on the roller surface.

[0044] Vacuum cleaners, floor scrubbers and other cleaning equipment are widely used for cleaning in various indoor and outdoor environments. These cleaning devices can scrape the floor with a roller brush and suck up debris through the air vent to clean the floor.

[0045] In related technologies, cleaning equipment includes a roller brush and a scraper. The roller brush has a cloth on its surface that can roll up garbage, debris, and water stains on the ground, while the scraper can remove the garbage, debris, and water stains stuck to the cloth, thus ensuring the continuous cleaning function of the roller brush.

[0046] However, existing scraper strips are made of hard materials, which can easily cause wear to the roller cloth, or existing scraper strips are designed as floating structures, but the structure is more complex.

[0047] To address the aforementioned technical problems, this application provides a floor brush device and cleaning equipment. The floor brush device includes a roller and a scraper. When the roller rotates, it scrapes the surface to be cleaned, picking up debris and water stains. During the cleaning process, the scraper scrapes the roller, preventing debris adhering to the roller surface from affecting its normal cleaning function. The scraper is at least partially made of a soft structure, allowing it to bend and have some floating space when scraping the roller, thus preventing wear on the roller. Furthermore, the scraper has a simple structure, is easy to manufacture and install, and reduces costs.

[0048] The following section provides examples illustrating the application scenarios of the floor brush device and cleaning equipment provided in the embodiments of this application.

[0049] The floor brush device provided in this application embodiment is applied to cleaning equipment. The types of products to which the floor brush device can be applied may include, but are not limited to, vacuum cleaners, mite removers, floor scrubbers, etc. Depending on the different product types, the cleaning equipment provided in this application embodiment can be used to clean surfaces of various materials, such as floors, sofas, etc. This application embodiment does not make any specific limitations in this regard.

[0050] Figure 1 This is a schematic diagram of the structure of the floor brush device provided in the embodiments of this application; Figure 2 A cross-sectional view of a floor brush device with a soft overall scraping structure provided in an embodiment of this application; Figure 3 An exploded view of the floor brush device provided in the embodiments of this application; Figure 4 A cross-sectional view of a floor brush device with a rigid scraping component provided in this embodiment of the application; Figure 5 This is a schematic diagram of the structure of the scraping component provided in the scraping section of the embodiment of this application; Figure 6 This is a schematic diagram of the structure of a scraping component with an integral scraping part provided in the embodiments of this application; Figure 7 This is a side view of the scraper provided in an embodiment of this application.

[0051] Reference Figures 1 to 7 As shown, this application provides a floor brush device 100, which is applied to cleaning equipment. When the cleaning equipment moves over a surface to be cleaned, the floor brush device 100 can contact the surface and clean it. The floor brush device 100 includes a main body 110, a roller 120, and a scraper 130. The roller 120 is rotatably connected to the main body 110. The surface of the roller 120 may be provided with a cloth. When the roller 120 rotates, the cloth can rub the surface to be cleaned, wiping away stubborn stains, absorbing water, and picking up debris. The scraper 130 is connected to the main body 110 and contacts the roller 120. When the roller 120 rotates, the scraper 130 can scrape the roller 120, removing water and debris absorbed by the roller 120, preventing the roller 120 from losing its cleaning function due to excessive water absorption or debris buildup. When the scraper 130 is installed, the distance between the scraper 130 and the surface of the roller 120 can be preset so that the scraper 130 contacts the roller 120. In this way, when the roller 120 rotates, the scraper 130 can scrape and squeeze the roller 120.

[0052] At least a portion of the scraper 130 is a soft structure, so that the scraper 130 can be bent when it scrapes the roller 120.

[0053] It is understandable that when the roller 120 rotates, it will also cause friction and compression on the scraper 130. When the roller 120 is covered with a cloth, its surface is uneven, and during the cleaning process, the cloth will stick to the dirt and debris, making the surface of the roller 120 even more uneven. During the rolling of the roller 120, the pressure on the scraper 130 will also fluctuate. By setting at least a part of the scraper 130 as a soft structure, the scraper 130 can bend and float continuously according to different pressures. While ensuring the scraping effect, it avoids excessive pressure on the roller 120, which would cause wear to the roller 120.

[0054] In some embodiments, the main body 110 may also be provided with an air intake 111, which may be located below the scraper 130. The cleaning device includes a main body, which is provided with an air intake unit and an air intake channel. The air intake 111 is connected to the air intake unit through the air intake channel. During cleaning, the roller 120 rotates and scrubs the surface to be cleaned. At the same time, the air intake unit is activated, which generates negative pressure in the air intake channel, thereby causing the air intake 111 to generate suction, sucking in the debris and water stains on the surface to be cleaned. Meanwhile, when the debris and water stains on the surface of the roller 120 are scraped off by the scraper 130, they can be sucked in by the air intake 111 and enter the debris collection device in the main body of the device through the air intake channel.

[0055] In one possible implementation, the scraping component 130 includes a pressure block 131 and a scraper 132. The scraper 132 includes a scraper body 1321 and a scraping part 1322. The scraping part 1322 is connected to the scraper body 1321 and contacts the roller 120 to scrape the roller 120. The pressure block 131 is disposed on the upper side of the scraper body 1321 and fixes the scraper body 1321.

[0056] It is understood that the scraper body 1321 is pressed onto the device body 110 by the pressure block 131. On the one hand, the pressure block 131 can fix the scraper body 1321, and on the other hand, the pressure block 131 can prevent the scraper 132 from bending too much and failing to effectively scrape the roller 120. The scraping part 1322 and the scraper body 1321 can be integrally formed, or they can be connected by adhesive bonding, riveting or other methods. This application embodiment does not make specific limitations.

[0057] As one possible implementation, the air intake 111 has an upper wall and a lower wall. The upper wall 1111 of the air intake is horizontally arranged, and the lower wall 1112 of the air intake is inclined, making the air intake 111 shaped like a trumpet. The lower side of the scraper body 1321 is connected to the upper wall 1111 of the air intake, so that the scraper body 1321 also extends in the horizontal direction. The horizontal pressure block 131 is connected to the upper side of the scraper body 1321 and cooperates with the upper wall 1111 of the air intake to press the scraper body 1321. The scraping part 1322 protrudes from the upper wall 1111 of the air intake and extends towards the roller 120. Along the cleaning direction of the floor brush device 100, the air intake 111 is located on the rear side of the roller 120. The lower wall 1112 of the air intake protrudes from the upper wall 1111 of the air intake and extends at least partly towards the lower side of the roller 120. The foremost point of the lower wall 1112 of the air intake is located in front of the foremost point of the scraping part 1322. When the scraping part 1322 scrapes off the dirt, debris and water stains on the surface of the roller 120, the dirt, debris and water stains will fall onto the lower wall 1112 of the air intake and enter the air intake 111 with the airflow.

[0058] The pressure block 131 can be a rigid structure, and its material can be rigid plastic or metal. The two sides of the pressure block 131 are connected to the two side walls of the device body 110. The pressure block 131, the scraper body 1321, and the upper wall 1111 of the air intake can be fixed and locked by bolts or screws, or they can be connected by adhesive bonding or other methods.

[0059] Reference Figure 1 The direction of movement of the floor brush device 100 during cleaning is defined as the Y direction, and the width direction of the device body 110 is defined as the X direction, which is perpendicular to the Y direction.

[0060] In some embodiments, one of the scraper body 1321 and the scraping part 1322 is a soft structure, and the other is a hard structure. The scraper body 1321 can be a soft structure and the scraping part 1322 a hard structure, or vice versa. This allows the scraping part 1322 to bend relative to the scraper body 1321 under pressure, creating a floating effect and preventing the scraping part 1322 from being too hard and causing wear on the roller 120. The scraping element 130 is used to scrape the roller 120. The soft structure can use high-hardness TPU (thermoplastic polyurethane elastomer), high-hardness TPE (thermoplastic elastomer), modified PP (polypropylene), or other tough materials, ensuring a certain scraping force while deforming under pressure. The hard structure can use ABS (acrylonitrile-butadiene-styrene copolymer), POM (polyoxymethylene), etc., as materials.

[0061] For example, the scraping part 1322 is a rigid structure, while the scraper body 1321 is a soft structure. The rigid structure ensures a better scraping effect, and when the scraping part 1322 is subjected to changes in force, the connection between the scraping part 1322 and the scraper body 1321 can bend to varying degrees, allowing the scraping part 1322 to float up and down, preventing the scraping part 1322 from causing wear on the roller 120. Figure 4 As shown.

[0062] For example, the scraping part 1322 is a soft structure and the scraper body 1321 is a hard structure. In this way, the hard scraper body 1321 can better limit the scraping part 1322 and prevent the soft scraping part 1322 from bending too much.

[0063] In other embodiments, both the scraper body 1321 and the scraping part 1322 are soft structures. The scraper body 1321 and the scraping part 1322 can use the same soft material or different soft materials. It is necessary to ensure that the scraping part 1322 has a certain scraping force while deforming under force.

[0064] It should be noted that the roller 120 extends along the width direction of the main body 110 of the device; the scraper 130 extends along the length direction of the roller 120, and the length of the scraper 130 matches the length of the roller 120, so that the scraper 130 can scrape the entire roller 120 to prevent any missed areas.

[0065] Reference Figure 5 In some embodiments, the scraping part 1322 includes multiple scraping structures, which are arranged sequentially at intervals along the length direction of the roller 120, and the length of the scraping part 1322 matches the length of the roller 120.

[0066] It is understandable that when the debris adhering to the surface of the roller 120 is large, the degree of bending generated by the scraping part 1322 during scraping will also increase. At this time, the area around the contact point between the scraping part 1322 and the debris will be deformed, thus affecting the scraping effect of the scraping part 1322. After the scraping part 1322 is set in segments, larger debris will only cause deformation to the scraping structure it contacts, without affecting the scraping effect of other scraping structures.

[0067] The length and number of segments of the multi-segment scraping structure are determined according to the actual working scenario, and this application embodiment does not impose specific limitations. The gap width between adjacent scraping structures should be minimized as much as possible to prevent the roller 120 corresponding to the gap from being left unscraped.

[0068] For example, the scraping part 1322 includes four scraping structures, which are spaced apart along the length of the scraping member 130 to reduce the impact of large-volume garbage and debris on the overall scraping part 1322.

[0069] Reference Figure 6 In some other embodiments, the scraping part 1322 is an integral structure, and the length of the scraping part 1322 matches the length of the roller 120. This ensures that the scraping part 1322 can scrape all parts of the roller 120 along its length, preventing any missed areas. At the same time, it can prevent garbage or debris from getting stuck or water stains from being left in the gaps of the scraping part 1322.

[0070] As one possible implementation, the scraping part 1322 has a bending angle relative to the scraper body 1321.

[0071] For example, in the right-side view of the floor brush device 100, as shown... Figure 2 As shown, the rotation direction of the roller 120 can be counterclockwise. The scraping part 1322 bends upward relative to the scraper body 1321. The rotation direction of the contact point between the roller 120 and the scraping part 1322 is consistent with the bending direction of the scraping part 1322, so that the scraping part 1322 can be tangent to the surface of the roller 120. In this way, when the roller 120 rotates, the debris on its surface is more easily removed from the surface of the roller 120 by the obstruction of the scraping part 1322. When the roller cloth of the roller 120 absorbs water, the water stains will also seep out from the roller cloth due to the squeezing effect of the scraping part 1322 on the surface of the roller 120. In this way, the roller 120 has a continuous cleaning ability.

[0072] This application provides a floor brush device 100 and a cleaning device. The floor brush device 100 includes a device body 110, a roller 120, and a scraper 130. The roller 120 is rotatably connected to the device body 110, and the scraper 130 is connected to the device body 110. The scraper 130 contacts the roller 120 to scrape the roller 120. At least a portion of the scraper 130 has a soft structure, allowing it to bend when scraping the roller 120. The scraper 130 of this application has a simple structure and a soft structure. When scraping the roller 120, the scraper 130 can float according to different forces, ensuring the scraping effect while avoiding wear on the surface of the roller 120.

[0073] 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.
