[0038] This embodiment discloses a roller-type cleaning device and cleaning equipment. The cleaning equipment includes a drive motor (not shown) and the roller-type cleaning device in this embodiment. The output end of the drive motor is connected to the roller 2 of the roller-type cleaning device, and the drive motor can drive the roller 2 to rotate. The drive motor is connected to the roller 2 of the roller-type cleaning device, which can drive the roller 2 to rotate, so that the roller 2 can operate continuously and efficiently when cleaning the floor. The rotation of the roller 2 achieves effective cleaning of stains on the floor, ensuring the stability and continuity of the cleaning work of the cleaning equipment, and improving the cleaning effect and ease of use of the cleaning equipment.

[0039] This embodiment discloses a roller-type cleaning device, such as... Figures 1-3 As shown, the roller-type cleaning device includes a housing 1, a roller 2, a first scraper 3, and a second scraper 4. The housing 1 has an open chamber 100. The roller 2 is rotatably installed inside the housing 1 and can absorb sewage. The axial extension direction of the roller 2 is a first direction. The first scraper 3 extends along the first direction and is disposed inside the housing 1 to scrape off the sewage on the roller 2. The first scraper 3 is disposed at the opening of the chamber 100, and the sewage from the roller 2 can enter the chamber 100 through the opening under the action of the first scraper 3. The second scraper 4 is disposed inside the housing 1, facing the end of the roller 2, and the extension direction of the second scraper 4 forms a preset angle with the first direction to guide the sewage into the chamber 100.

[0040] In this embodiment, the roller-type cleaning device operates with the roller 2 rotating within the housing 1. A first scraper 3 extends along a first direction to scrape away wastewater from the surface of the roller 2. The housing 1 contains an open chamber 100 through which wastewater enters. A second scraper 4 is positioned towards the end of the roller 2, with its extension direction forming a preset angle with the first direction. This guides the wastewater from the end of the roller 2 into the chamber 100, achieving efficient wastewater collection. This roller-type cleaning device uses the first scraper 3 to remove wastewater from the roller 2 and collect it in the chamber 100, while the second scraper 4, at a preset angle, prevents wastewater from dripping onto the ground and causing secondary pollution. This also reduces the risk of wastewater seeping into and corroding other components, extends the lifespan of the roller-type cleaning device, improves cleaning efficiency, and reduces costs.

[0041] The cleaning device in this embodiment uses the aforementioned roller-type cleaning device. During operation, the drive motor drives the roller 2 to rotate inside the housing 1. The first scraper 3 scrapes away the sewage on the roller 2 and guides it into the chamber 100. The second scraper 4 guides the sewage at the end of the roller 2 into the chamber 100 at a preset angle. This cleaning device can avoid sewage dripping and component corrosion, extend service life, improve cleaning efficiency, reduce operating costs, and achieve efficient sewage collection.

[0042] In this embodiment, the extension direction of the second wiper element 4 forms a preset angle with the first direction. The preset angle is defined as the acute angle between the second wiper element 4 and the first direction. Optionally, the preset angle can be 30 degrees, 45 degrees, 60 degrees, 75 degrees, etc., and is not specifically limited here.

[0043] like Figures 3-5As shown, the second squeegee 4 includes a first guide section 41, which is connected to the housing 1. At least a portion of the surface of the first guide section 41 can adhere to the surface of the roller 2. When the roller 2 rotates, the first guide section 41 can scrape off the wastewater on the roller 2. The first guide section 41 effectively prevents wastewater from being thrown out with the rotation of the roller 2, avoiding wastewater dripping onto the ground or seeping into components, improving wastewater collection efficiency, reducing secondary pollution and component corrosion, and ensuring the cleaning effect and service life of the roller-type cleaning device.

[0044] In this embodiment, the first guide section 41 is a columnar structure. The side surface of the columnar structure is composed of four irregular curved surfaces. One of the irregular curved surfaces is attached to and fixedly connected to the inner wall of the housing 1, and another irregular curved surface is in contact with the surface of the roller 2. While scraping away sewage along the rotation trajectory of the roller 2, the curvature of the other irregular curved surfaces guides the sewage along the inner wall of the housing 1 to the chamber 100. This enhances the scraping adhesion and improves the cleaning efficiency, while the double-curved surface fixing structure improves the sealing performance and reduces the risk of sewage leakage and dripping from both ends. In other embodiments, the number of irregular curved surfaces constituting the side surface of the first guide section 41 can also be three, five, six, etc., and no specific limitation is made here.

[0045] In this embodiment, the first guide section 41 is equipped with an elastic element, which can tightly conform to the surface of the roller 2 through elastic deformation, adapting to the changes in the contour of the roller 2 under different rotation conditions, ensuring no gap residue during wiping and improving the efficiency of sewage removal. At the same time, the buffering effect of the elastic element can reduce the rigid friction between the second wiping component 4 and the roller 2, reduce operating noise and component wear, extend the service life of the second wiping component 4, and the elastic sealing effect can effectively prevent sewage from seeping into both ends of the roller 2, reducing secondary pollution.

[0046] Optionally, the elastic element can be an elastic gasket, rubber gasket, silicone gasket, etc., without specific limitations.

[0047] like Figures 3-5 As shown, the second scraper 4 also includes a second guide section 42. The first guide section 41 is connected to the second guide section 42. The second guide section 42 is constructed as a pyramid, with the base of the pyramid connected to the first guide section 41 and the tip of the pyramid facing the chamber 100. The second guide section 42 can guide the sewage at the end of the roller 2 along the surface of the pyramid to the chamber 100. The guiding property of the pyramid structure enhances the sewage collection efficiency. The sewage is accelerated to the chamber 100 by gravity and the guiding effect of the inclined surface of the pyramid, preventing sewage from accumulating and flowing out at the end of the roller 2. This forms an integrated scraping and guiding path, allowing sewage to be scraped by the first guide section 41 and then directly guided by the second guide section 42, preventing sewage from remaining on the surface of the roller 2 or spreading to both ends, improving sewage recovery efficiency and reducing secondary pollution, and increasing the sewage collection capacity and service life of the roller cleaning device.

[0048] In this embodiment, the second guide segment 42 is constructed as a triangular pyramid. In other embodiments, the second guide segment 42 can also be constructed as a square pyramid, a pentagonal pyramid, etc., and no specific limitation is made here.

[0049] like Figures 3-5 As shown, the roller-type cleaning device also includes a suction component (not shown). The housing 1 has a suction port 11, which communicates with the chamber 100. The suction port 11 is connected to the suction component, which is used to suction wastewater from the chamber 100. With the suction port 11 connected to the chamber 100, the suction component can promptly remove wastewater from the chamber 100, preventing wastewater accumulation and overflow, reducing the corrosion of the roller 2 and the interior of the housing 1 by residual wastewater. Combined with the first scraper 3 and the second scraper 4, it achieves integrated treatment of wastewater scraping, collection, and suction, further reducing the risk of secondary pollution.

[0050] Alternatively, the suction device can be a centrifugal water pump, a diaphragm pump, a vacuum generator, etc., without specific limitations.

[0051] like Figures 4-5 As shown, the first wiper component 3 includes a support portion 31 and a contact portion 32. One end of the support portion 31 is connected to the housing 1, and the other end is connected to the contact portion 32. The contact portion 32 can at least partially make line contact with the surface of the roller 2. The first wiper component 3 is connected to the housing 1 through the support portion 31, and the contact portion 32 makes line contact with the surface of the roller 2, which can closely fit the curved surface of the roller 2 to ensure that sewage is wiped away without dead corners. The line contact design reduces frictional resistance, reduces component wear, and improves the wiping sealing performance. It also allows sewage to be efficiently introduced into the chamber 100 along the contact portion 32, enhancing the sewage collection effect and the durability of the roller-type cleaning device.

[0052] In this embodiment, the contact part 32 is made of rubber. Rubber has high elasticity, and the rubber contact part 32 can closely fit the surface of the roller 2, achieving line contact between the contact part 32 and the roller 2, ensuring no wastewater is missed and improving scraping efficiency. In addition, rubber is wear-resistant and corrosion-resistant, which can reduce frictional wear between the contact part 32 and the roller 2, extending its service life. At the same time, the flexibility of rubber is not likely to damage the surface of the roller 2, reducing operating noise and ensuring long-term stable operation of the roller-type cleaning device.

[0053] In other embodiments, the contact portion 32 is made of silicone. Silicone is soft and highly elastic, allowing it to closely conform to the surface of the roller 2, achieving line contact between the contact portion 32 and the roller 2 for efficient cleaning and preventing wastewater residue. Furthermore, silicone is heat-resistant, anti-aging, suitable for long-term use in humid environments, and is non-toxic and odorless, meeting environmental protection requirements. Simultaneously, the flexibility of silicone reduces frictional wear between the contact portion 32 and the roller 2, extending its service life, reducing operating noise, and minimizing damage to the roller 2 surface, ensuring long-term stable operation of the roller-type cleaning device.

[0054] like Figure 3 As shown, the roller-type cleaning device includes two second squeegee components 4, which are symmetrically arranged on the housing 1, facing opposite ends of the roller 2. The synchronized squeegee components 4 at both ends create a symmetrical flow path, effectively intercepting wastewater spreading towards both ends of the roller 2, preventing secondary pollution from wastewater dripping onto the ground. The symmetrical structure also balances the squeegee resistance during roller 2 rotation, reducing eccentric wear. Simultaneously, the synchronized wastewater recovery at both ends improves overall wastewater discharge efficiency and reduces the risk of residual wastewater seeping into and corroding other components.

[0055] In this embodiment, the roller-type cleaning device also includes a central shaft (not shown), through which the roller 2 passes. Both ends of the central shaft are rotatably connected to the housing 1 via bearings. The roller 2 can rotate stably, reducing axial movement and radial offset, ensuring uniform contact between the first and second scraper components 3 and the roller 2, thus improving wastewater removal efficiency. Simultaneously, the bearing support reduces rotational friction loss and extends the lifespan of the roller-type cleaning device.

[0056] In this embodiment, roller 2 is made of sponge. The porous structure of the sponge can efficiently absorb sewage and stains on the ground, improving cleaning efficiency. Its soft texture can conform to uneven surfaces and clean deep crevices. After absorbing water, it increases in weight, enhancing the pressure on the ground and optimizing the cleaning effect.

[0057] In other embodiments, the roller 2 is made of nylon fiber. Nylon fiber, with its strong fiber structure and dense fibers, can efficiently pick up stubborn stains, improving cleaning power. The fibers are wear-resistant and tensile-resistant, have a long service life, and the rough surface texture enhances friction with the ground. At the same time, nylon material dries quickly, reducing bacterial growth and ensuring cleanliness and hygiene.

[0058] Obviously, the above embodiments of this utility model are merely examples for clearly illustrating the present utility model, and are not intended to limit the implementation of the present utility model. Those skilled in the art can make various obvious changes, readjustments, and substitutions without departing from the protection scope of this utility model. It is neither necessary nor possible to exhaustively describe all embodiments here. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of this utility model should be included within the protection scope of the claims of this utility model.
