Abstract
Description
Technical Field
[0001] This application belongs to the field of cleaning appliance technology, specifically relating to a cleaning robot. Background Technology
[0002] Cleaning robots are a popular type of smart home appliance. They typically have wheels and cleaning components on their bottom, enabling them to automatically clean floors in a room. Their cleaning components include a roller brush, a water outlet, and a scraper assembly. The roller brush is thoroughly wetted by the water outlet, allowing it to clean the surface. The scraper assembly then removes any remaining dirt from the roller brush surface.
[0003] However, existing cleaning robots have the following drawbacks in their cleaning components: First, existing cleaning robots usually place the water outlet component and the dirt scraping component separately in different positions on the body, resulting in a complex internal pipeline layout and numerous assembly steps; Second, the pressure distribution of existing dirt scraping components in contact with the roller brush is uneven and the friction is limited, making it difficult to remove stubborn stains adsorbed on the roller brush. Utility Model Content
[0004] To overcome the shortcomings of the prior art, this application proposes a cleaning robot, specifically implemented through the following technical solution:
[0005] A cleaning robot, comprising: Organism; A roller brush, which is rotatably mounted on the bottom of the machine body, is used to clean the surface to be cleaned; A scraper support is disposed in the area of the machine body near the roller brush, and the scraper support is provided with: A water outlet component, one side of which is connected to a clean water tank and the other side of which faces the roller brush, is used to deliver clean water from the clean water tank to the surface of the roller brush to wet the roller brush; A scraper component, the end of which extends toward the roller brush, the end of which has a toothed structure that squeezes the roller brush to scrape away sewage and dirt from the roller brush as it rolls.
[0006] In one specific embodiment, the length direction of the scraper bracket is the same as the length direction of the roller brush; The water outlet component and the scraper component are arranged sequentially along the height direction of the scraper bracket, and the scraper component is closer to the bottom of the machine body than the water outlet component.
[0007] In one specific embodiment, the scraping component includes a metal scraper strip, which is disposed on the scraper strip bracket and close to the bottom of the body; The metal scraper includes stainless steel scraper, aluminum alloy scraper, aluminum scraper, titanium scraper, or titanium alloy scraper.
[0008] In one specific embodiment, the scraper component includes a first part and a second part, the first part being connected to the scraper support; the second part being bent relative to the first part, and the second part having the toothed structure.
[0009] In one specific embodiment, the bending angle between the first part and the second part is between 90° and 160°.
[0010] In one specific embodiment, the tooth structure includes a plurality of teeth, which are located at the ends of the scraper component and are spaced apart along the length of the scraper component.
[0011] In one specific embodiment, the water outlet component includes a plurality of water outlets, which are spaced apart along the length direction of the scraper bracket.
[0012] In one specific embodiment, a water outlet space is formed between the scraper bracket and the roller brush, and the water outlet is connected to the water outlet space.
[0013] In one specific embodiment, the surface of the roller brush is covered with a felt cloth, which is used to receive and fully saturate the clean water supplied from the clean water tank.
[0014] In one specific embodiment, the roller brush has at least two roller brushes, which are spaced apart along the length or width of the machine body; each roller brush is equipped with a scraper bracket, a water outlet component, and a scraper component.
[0015] This application has at least the following beneficial effects: This application belongs to the field of cleaning appliance technology, specifically relating to a cleaning robot, comprising: a body; a roller brush, rotatably mounted on the bottom of the body for cleaning surfaces to be cleaned; a scraper bracket, located on the body near the roller brush, the scraper bracket having: a water outlet component, one side of which communicates with a clean water tank, and the other side facing the roller brush, for delivering clean water from the tank to the surface of the roller brush to wet it; and a scraper component, the end of which extends toward the roller brush and has a small tooth structure that squeezes the roller brush to scrape away wastewater and dirt as it rolls. This application simplifies the internal space layout of the body by mounting both the water outlet component and the scraper component on the scraper bracket, reducing assembly complexity and production costs; furthermore, the small tooth structure of the scraper component increases the contact area and friction with the roller brush surface, enabling more thorough removal of stubborn stains from the gaps between the roller brush fibers.

[0019] Various embodiments of this application will be described more fully below. This application may have various embodiments, and adjustments and changes may be made therein. However, it should be understood that there is no intention to limit the various embodiments of this application to the specific embodiments disclosed herein, but rather this application should be understood to cover all adjustments, equivalents, and / or alternatives falling within the spirit and scope of the various embodiments of this application.
[0020] In the following, the terms “comprising” or “may include” as used in the various embodiments of this application indicate the presence of the disclosed functions, operations, or elements, and do not limit the addition of one or more functions, operations, or elements. Furthermore, as used in the various embodiments of this application, the terms “comprising,” “having,” and their cognates are intended only to indicate a particular feature, number, step, operation, element, component, or combination of the foregoing, and should not be construed as primarily excluding the presence of one or more other features, numbers, steps, operations, elements, components, or combinations of the foregoing, or the possibility of adding one or more combinations of features, numbers, steps, operations, elements, components, or combinations of the foregoing.
[0021] like Figure 1-6 As shown, a cleaning robot includes: Body 1; The roller brush 2 is rotatably mounted on the bottom of the body 1 and is used to clean the surface to be cleaned; The scraper support 3 is located in the area of the machine body 1 near the roller brush 2, and the scraper support 3 is equipped with: Water outlet component 4, one side of which is connected to the clean water tank and the other side of which faces the roller brush 2, is used to deliver clean water from the clean water tank to the surface of the roller brush 2 to wet the roller brush 2. The scraper component 5 extends toward the roller brush 2 at its end and has a toothed structure 53 at its end. The toothed structure 53 presses against the roller brush 2 to scrape away sewage and dirt from the roller brush 2 as it rolls.
[0022] This application simplifies the internal space layout of the machine body 1 by setting both the water outlet component 4 and the scraper component 5 on the scraper bracket 3, reducing assembly complexity and production costs, facilitating quick replacement of components during later maintenance, and improving product reliability and user convenience. Furthermore, the small tooth structure 53 of the scraper component 5 increases the contact area and friction with the surface of the roller brush 2, enabling it to more thoroughly remove stubborn stains from the gaps between the fibers of the roller brush 2, significantly improving cleaning efficiency and cleaning effect.
[0023] like Figure 1-6As shown, the length direction of the scraper bracket 3 is the same as the length direction of the roller brush 2; the water outlet component 4 and the scraper component 5 are arranged sequentially along the height direction of the scraper bracket 3, and the scraper component 5 is closer to the bottom of the body 1 than the water outlet component 4. This application, through the design that the length direction of the scraper bracket 3 is consistent with the length direction of the roller brush 2, ensures that the water outlet component 4 and the scraper component 5 are evenly distributed along the axial direction of the roller brush 2, so that the functions of clean water delivery and dirt removal cover the entire working width of the roller brush 2. Furthermore, the sequential arrangement of the water outlet component 4 and the scraper component 5 along the height direction of the scraper bracket 3 (water outlet above, scraper below) forms a forward operation process of "wetting first, then scraping," thereby improving the efficiency of a single cleaning cycle. Moreover, the structure of the scraper component 5 being closer to the bottom of the body 1 than the water outlet component 4 results in a shorter distance between its scraping end and the surface to be cleaned, and a more concentrated contact pressure.
[0024] The scraping component 5 includes a metal scraper, which is mounted on the scraper bracket 3 and located near the bottom of the body 1. The metal scraper may be made of stainless steel, aluminum alloy, aluminum, titanium, or titanium alloy. This application uses a metal scraper, which offers higher mechanical strength and wear resistance compared to traditional plastic scrapers. During long-term friction with the fibers of the roller brush 2, the metal scraper is less prone to deformation or wear, ensuring that the small tooth structure 53 maintains sharp contact and effectively removes dirt. This significantly reduces the risk of decreased cleaning efficiency due to scraper aging and extends the overall service life of the scraping component 5. Furthermore, considering that metal scrapers are prone to rust when in contact with water, the metal scraper in this application includes stainless steel, aluminum alloy, aluminum, titanium, or titanium alloy scrapers. Using such scrapers effectively avoids rusting and extends the overall service life of the scraping component 5.
[0025] In one embodiment, the metal scraper includes a stainless steel scraper, which is suitable for use in wet or chemical cleaning environments and avoids corrosion that could affect the scraping effect.
[0026] In another embodiment, the metal scraper includes an aluminum alloy scraper or an aluminum scraper, which reduces weight while maintaining strength, thereby reducing the load on the scraper support 3; In other embodiments, the metal scraper includes a titanium scraper or a titanium alloy scraper, which combines high strength with biocompatibility, making it suitable for cleaning scenarios in the medical or food industries where hygiene requirements are extremely high.
[0027] like Figure 2 , 3As shown, the scraper component 5 includes a first part 51 and a second part 52. The first part 51 is connected to the scraper support 3; the second part 52 is bent relative to the first part 51, and has a small tooth structure 53. The scraper component 5 of this application is fixedly connected to the scraper support 3 via the first part 51. The bent design of the second part 52 allows the small tooth structure 53 to fit the surface of the roller brush 2 at a more optimal angle, thereby improving the accuracy of scraping. Furthermore, the small tooth structure 53 of the second part 52 increases the contact area and friction with the surface of the roller brush 2, enabling it to more thoroughly remove stubborn stains from the gaps between the fibers of the roller brush 2, significantly improving cleaning efficiency and cleaning effect.
[0028] The bending angle α between the first part 51 and the second part 52 is between 90° and 160°. This application limits the bending angle to within the range of 90° to 160°, which optimizes the contact pressure between the small tooth structure 53 and the surface of the roller brush 2 through angle design. When the angle is 90° (vertical bending), the squeezing force of the scraping component 5 on the roller brush 2 is concentrated, which is suitable for hard roller brush 2 or stubborn stains. When the angle increases to 160° (close to a gentler curve), the squeezing force is dispersed, which is more suitable for soft fiber roller brush 2 or daily cleaning, avoiding deformation or wear of the roller brush 2 fibers due to excessive pressure. It can be seen that the bending angle between the first part 51 and the second part 52 within the range of 90° to 160° achieves a precise balance between scraping efficiency and the lifespan of the roller brush 2.
[0029] like Figure 1-6 As shown, the small tooth structure 53 includes multiple teeth 531 located at the ends of the scraper component 5 and spaced apart along the length of the scraper component 5. The small tooth structure 53, composed of multiple teeth 531 spaced apart along the length of the scraper component 5, ensures that the scraping force is evenly distributed across the surface of the roller brush 2. Compared to single-tooth or continuous tooth structures, the spaced-apart multiple teeth 531 avoid deformation of the roller brush 2 fibers caused by localized pressure concentration. Simultaneously, multi-point contact ensures that wastewater and dirt are scraped away simultaneously along the entire length of the roller brush 2, eliminating cleaning blind spots at edges or in the middle, making it particularly suitable for large-area cleaning scenarios with wide-width roller brushes 2. Furthermore, the spacing between adjacent teeth 531 forms a flow channel, allowing scraped wastewater and dirt to quickly detach from the surface of the roller brush 2 along the channel. This design avoids the accumulation of dirt between the scraper component 5 and the roller brush 2 (as is common in traditional continuous tooth structures), reduces secondary contamination of the roller brush 2 caused by repeated friction of dirt, and reduces the risk of the scraper component 5 failing due to dirt clogging, thus maintaining long-term stable dirt scraping performance.
[0030] like Figure 1-6As shown, the water outlet component 4 includes multiple water outlets 41, which are spaced apart along the length of the scraper support 3. The water outlet component 4 of this application achieves uniform distribution of clean water on the surface of the roller brush 2 through multiple water outlets 41 spaced apart along the length of the scraper support 3. Compared to a single water outlet design, the spaced arrangement of multiple water outlets 41 avoids localized over-wetting or under-drying in the middle or edge areas of the roller brush 2 due to concentrated or dispersed water flow, ensuring uniform absorption of clean water by the fibers along the entire length of the roller brush 2, improving the consistency of the wetting effect, and is especially suitable for large-area cleaning scenarios with a wide-width roller brush 2.
[0031] like Figure 5 , 6 As shown, a water outlet space 42 is formed between the scraper bracket 3 and the roller brush 2, and the water outlet 41 is connected to the water outlet space 42. The water outlet space 42 formed between the scraper bracket 3 and the roller brush 2 can serve as a buffer cavity for clean water delivery, significantly reducing the impact of water flow on the roller brush 2, and ensuring that the fibers of the roller brush 2 are uniformly wetted, thereby improving its ability to adsorb dust and stains during cleaning. It is especially suitable for large-area cleaning scenarios using a wide-width roller brush 2.
[0032] The roller brush 2 has a surface covered with a felt cloth 21, which is used to receive and fully saturate the clean water supplied from the clean water tank. The felt cloth 21 covering the surface of the roller brush 2 has a porous fiber structure, allowing it to quickly absorb and store the clean water supplied from the clean water tank. Compared to traditional hard rubber brushes or short-fiber roller brushes 2, the felt cloth 21 significantly improves water absorption rate and water retention capacity, ensuring that clean water penetrates evenly into the deep layers of the fibers.
[0033] like Figure 1-6 As shown, the roller brush 2 has at least two roller brushes, which are spaced apart along the length or width of the body 1; each roller brush 2 is equipped with a scraper support 3, a water outlet component 4, and a scraping component 5. This application achieves simultaneous cleaning of multiple areas by arranging at least two roller brushes 2 spaced apart along the length or width of the body 1. Furthermore, each roller brush 2 is independently equipped with a scraper support 3, a water outlet component 4, and a scraping component 5, avoiding mutual interference between water flow or scraping actions when multiple roller brushes 2 are working, thus improving operational stability.

For example, the expression "A or B" or "at least one of A and / or B" may include A, may include B, or may include both A and B.
