Description
Technical Field
[0001] The present disclosure relates to a surface cleaning assembly for cleaning a surface and a wet cleaning device including such a surface cleaning assembly. Background Art
[0002] With the development of automated cleaning devices, more and more automated cleaning devices, such as floor scrubbers and sweeping robots, are gradually becoming the first choice for commercial and household cleaning due to their high efficiency and labor-saving features. Automated cleaning devices can automatically perform cleaning tasks such as vacuuming, sweeping, and mopping, significantly improving cleaning efficiency while reducing the intensity of manual labor. A wet cleaning device (such as a floor scrubber) is an efficient floor cleaning device that uses a wet cleaning fluid (such as water) and is suitable for various floors, such as tiles and marble, and is particularly suitable for use in places such as shopping malls, schools, hospitals, and households.
[0003] Current wet cleaning devices include a rotary brush. During a cleaning operation, the rotary brush rotates at a high speed so that the cleaning elements on its surface rub against the floor to wipe the floor. When the rotary brush rotates, water is applied to the rotary brush to perform a wet cleaning operation to more effectively remove stubborn stains and dust on the floor, which can further improve cleaning efficiency and reduce bacteria and microorganisms at the same time. However, since the rotary brush rotates at a high speed, excessive water or unevenly distributed water in the cleaning elements may be thrown out due to centrifugal force and fall onto the floor. The water in the cleaning elements may also accumulate and drip onto the floor during the rotation of the rotary brush, resulting in unwanted sheet-like water stains.
[0004] Therefore, a solution that can overcome the above-mentioned defects is needed. Summary of the Utility Model
[0005] The present disclosure aims to propose a better solution to the above problems, so as to prevent the cleaning fluid from undesirably falling onto the floor.

[0027] The present disclosure will be described below with reference to the accompanying drawings. It should be understood that the detailed description and specific examples, although explaining the exemplary embodiments of the surface cleaning assembly and the surface cleaning device, are only for illustrative purposes and are not intended to limit the scope of the present disclosure. These and other features, aspects and advantages of the surface cleaning assembly and the surface cleaning device of the present disclosure can be better understood in conjunction with the following description, the appended claims and the drawings. It should be understood that the drawings are only schematic and not drawn to scale. It should also be understood that the same reference numerals represent the same or similar components throughout the drawings.
[0028] Figure 1An example of the wet cleaning device 1 is schematically shown. However, the wet cleaning device 1 according to the present disclosure is not limited to that shown in the figure. In some embodiments, the wet cleaning device 1 may include a handle for a user to hold and push and pull. The wet cleaning device may also include a blower module for suction, a first container for containing clean cleaning fluid, and a second container for containing dirt. As Figure 1 shown, the wet cleaning device 1 includes a surface cleaning assembly 10. When in a non-use state, the surface cleaning assembly 10 can be placed in the base 11. The surface cleaning assembly 10 includes a rotatable roller brush 100. The roller brush 100 rubs against the surface during rotation to wipe the surface. The axial direction A of the roller brush 100 is shown in Figure 1 .
[0029] As Figure 2 shown, the outer surface of the roller brush 100 is provided with cleaning elements 101. The cleaning elements 101 can absorb cleaning fluid, such as water or disinfectant solution, etc. The cleaning elements 101 can be made of hygroscopic materials, such as cloth, sponge, fluff, etc. The surface cleaning assembly 10 further includes a housing 200 that at least partially covers the roller brush 100. The housing 200 includes a front end along the forward movement direction F of the surface cleaning assembly 10 and a rear end opposite to the front end. Under the pushing action of the user, the surface cleaning assembly can move forward along the forward movement direction F on the surface 11 to be cleaned, and under the pulling-back action of the user, move backward along the direction opposite to the forward movement direction F.
[0030] As Figure 2 shown, the housing 200 includes a first housing part 201 and a second housing part 202. The first housing part 201 at least partially covers the upper part of the roller brush 100. The second housing part 202 includes a first end and a second end. The first end of the second housing part 202 is connected to the first housing part 201 to form a cavity for at least partially accommodating the roller brush 100. The second housing part 202 at least partially covers the lower part of the roller brush. In some embodiments, the housing 200 is openable to allow the removal of the cleaning elements 101.
[0031] As Figure 2 shown, the housing 200 includes a squeegee 300 in contact with the cleaning elements 101 at the front end. The squeegee 300 is arranged to scrape off excess cleaning fluid from the cleaning elements 101 and to distribute the cleaning fluid evenly on the cleaning elements 101. In some embodiments, the squeegee 300 can be arranged at the second end of the second housing part 202. In some embodiments, the squeegee 300 is arranged adjacent to the bottom of the housing 200.
[0032] Figure 3 A side cross-sectional view of a part of the surface cleaning assembly according to the present disclosure is schematically shown. As Figure 3As shown, a fluid guiding member 310 is provided at an end of the squeegee 300 in contact with the cleaning element 101 to prevent the cleaning fluid in the cleaning element 101 from falling onto the surface to be cleaned 11 (such as Figure 2 as shown) during the rotation of the rotary brush. The fluid guiding member 310 can guide the excess or unevenly distributed cleaning fluid on the cleaning element 101 to prevent the cleaning fluid from being thrown out due to the centrifugal force generated by the high-speed rotation of the rotary brush.
[0033] In some embodiments, as Figure 3 shown, the surface cleaning assembly 10 further includes a first scraping member 203 for scraping off dirt (such as hair, etc.) remaining on the rotary brush 100. The first scraping member 203 can be disposed at the rear end of the housing 200 so that the scraped dirt is sucked into the second container by the action of the blower module.
[0034] In some embodiments, the surface cleaning assembly 10 further includes a second scraping member 204 for scraping off dirt on the surface to be cleaned 11. The second scraping member 204 can be disposed at the rear end of the housing 200. With the aid of the second scraping member 204, stubborn stains on the ground can be effectively scraped off.
[0035] Figure 4 A partial enlarged view of the squeegee 300 is schematically shown. As Figure 4 shown, the fluid guiding member 310 includes a groove 302. The groove 302 is located in the squeegee 300 and is used for temporarily storing the cleaning fluid. The groove 302 can extend along the axial direction A of the rotary brush 100. The groove 302 is also adjacent to the rotary brush 100, especially adjacent to the cleaning element 101 of the rotary brush. The groove 302 can temporarily store the cleaning fluid thrown out from the cleaning element during the rotation of the rotary brush 100. Subsequently, the cleaning fluid stored in the groove 302 can be adsorbed onto the cleaning element 101 again as the rotary brush rotates. In some embodiments, the groove 302 can be located at an end of the squeegee 300 adjacent to the surface to be cleaned. With the aid of the temporary storage function of the groove, the time required for the cleaning fluid to penetrate into the cleaning element can be extended, thereby alleviating the excess or unevenly distributed cleaning fluid caused by the cleaning element not having enough time to absorb the cleaning fluid. Thus, it can help to evenly distribute the cleaning fluid on the cleaning element and avoid waste caused by the cleaning fluid being thrown out, thereby improving the utilization rate of the cleaning fluid.
[0036] In some embodiments, the groove 302 can be integrally formed with the squeegee 300. In some embodiments, by making the contact portion of the squeegee 300 with the cleaning element 101 extend in a direction away from the surface to be cleaned 11 (for example, upward), the groove 302 can be formed.
[0037] In some embodiments, as Figure 5As shown, the fluid guiding member 310 at the front end of the housing 200 includes a plurality of saw teeth 301. The saw teeth 301 can be used to guide the cleaning fluid, and more specifically, to disperse the cleaning fluid. The saw teeth 301 are arranged to contact the cleaning element 101, and during the rotation of the rotatable brush 100, disperse the cleaning fluid on the cleaning element 101, so that the volume of the cleaning fluid becomes smaller, thereby preventing the cleaning fluid from aggregating into droplets that are likely to drip onto the surface to be cleaned.
[0038] In some embodiments, as Figure 6 shown, the cross-section of the saw teeth 301 has a triangular shape. During the rotation of the rotatable brush 100, the saw teeth 301 and the cleaning element 101 rub against each other, thereby dispersing the large sheet-like cleaning fluid on the cleaning element 101 into minute cleaning fluid or in a mist form. In this way, the cleaning fluid on the cleaning element 101 is not likely to aggregate and is not easily thrown out due to centrifugal force. Specifically, during the rotation of the rotatable brush, the apex of the triangular saw tooth first contacts the cleaning element, and then due to the rotation of the rotatable brush, the side of the triangular saw tooth inserts into a part of the cleaning element 101 or abuts against the cleaning element, thereby dispersing the large-volume cleaning fluid on the cleaning element into a smaller volume.
[0039] In some embodiments, as Figure 7 shown, the fluid guiding member 310 may include both the saw teeth 301 and the grooves 302. Similar to the above, the grooves 302 can temporarily store the cleaning fluid, and the saw teeth 301 can disperse the cleaning fluid on the cleaning element. The combination of the two can achieve a better effect. By virtue of the combination of the two, the excessive or unevenly distributed cleaning fluid on the cleaning element will not drop to the ground, thereby improving the cleaning efficiency and enhancing the user experience.
