[0031] The embodiments of the present invention are described in detail below, examples of which are shown in the accompanying drawings. The embodiments described below with reference to the accompanying drawings are exemplary and intended to explain the present invention, and should not be construed as limiting the present invention.

[0032] The following is a reference appendix. Figures 1 to 5 This invention describes a roller brush 1, a cleaning head, and a cleaning device according to embodiments of the present invention.

[0033] like Figure 1 , Figure 4 and Figure 5 As shown, the roller brush 1 of this utility model embodiment includes: a brush shaft 11 and a cleaning cloth 12. The cleaning cloth 12 is wound around the brush shaft 11, and the outer wall of the cleaning cloth 12 has a pile layer 121. The weight of the cleaning cloth 12 is A, wherein 700g / m³ 2 ≤A≤800g / m 2 .

[0034] According to the embodiment of the present invention, the roller brush 1 has a pile layer 121 on the outer wall of the cleaning cloth 12, and the basis weight A of the cleaning cloth 12 is 700 g / m². 2 -800g / m 2 The selection of the appropriate type ensures that the cleaning cloth 12 has good water absorption, reduces water stains left by the roller brush 1 after cleaning, and the roller brush 1 has a good effect on capturing dirt, which helps to improve the cleaning effect of the roller brush 1.

[0035] For example, the weight A of cleaning cloth 12 can be 700 g / m². 2 720g / m 2 730g / m 2 740g / m 2 750g / m 2 760g / m 2 780g / m 2 800g / m 2 .

[0036] The inventors of this utility model discovered through experimental research that when the weight A of the cleaning cloth 12 is less than 700 g / m², 2 At this time, the density of the pile layer 121 of the cleaning cloth 12 is low, the water absorption is poor, and the sealing structure formed by the roller brush 1 and the scraper 3 is poor. As a result, when the roller brush 1 cleans the floor, it is not easy to guide the dirt into the dust suction port 211 of the cleaning head, which reduces the cleaning effect of the roller brush 1.

[0037] When the weight A of cleaning cloth 12 is greater than 800 g / m 2 When the roller brush 1 is wet, it becomes heavier, which increases the energy required to drive the roller brush 1 to rotate, reduces the overall battery life, and makes it easy for water stains to remain after cleaning, affecting the user experience.

[0038] Therefore, in this embodiment of the invention, the roller brush 1 has a weight A of 700 g / m² for the cleaning cloth 12. 2 -800g / m 2 By selecting the appropriate parameters, the performance of the roller brush 1 in capturing dirt particles, the water absorption performance, and the wiping performance can be improved, and the energy consumption of the whole machine can be reduced.

[0039] Optionally, such as Figure 5As shown, the thickness of the pile layer 121 is B, where 6.5 mm ≤ B ≤ 7.5 mm. In other words, the pile length of the pile layer 121 is B. For example, the thickness B of the pile layer 121 can be 6.5 mm, 6.7 mm, 6.9 mm, 7.0 mm, 7.1 mm, 7.3 mm, or 7.5 mm. When the pile layer 121 adopts the above-mentioned dimensions, the ability of the roller brush 1 to capture dirt particles, the water absorption performance of the roller brush 1, and the wiping performance of the roller brush 1 can be further improved.

[0040] like Figure 5 As shown, the pile layer 121 includes polyester fibers (not shown) and polyester filaments (not shown), and the cleaning cloth 12 also includes a base layer 122, on which polyester fibers and polyester filaments are mixed and arranged. That is, polyester fibers and polyester filaments each account for a certain proportion in the pile layer 121. Polyester fibers have the advantage of good abrasion resistance, but their water absorption and moisture regain are somewhat poor. Polyester filaments have the advantage of good water absorption, but their abrasion resistance is not as good as that of polyester fibers. Therefore, the roller brush 1 of this embodiment adopts the above arrangement of the pile layer 121, which can ensure that the cleaning cloth 12 has good water absorption and abrasion resistance, and is conducive to extending the service life of the cleaning cloth 12.

[0041] Optionally, the ratio of polyester fiber to polyester filament is C, where 1.5 ≤ C ≤ 2.5. For example, the ratio of polyester fiber to polyester filament can be 1.5, 1.8, 2.0, 2.2, or 2.5. This further reduces water stains after cleaning with the roller brush 1, improves abrasion resistance, and extends service life.

[0042] In a specific example, such as Figure 5 As shown, the base layer 122 is made of polyester fabric, with a polyester portion thickness of approximately 0.5 mm. The polyester fiber (polyester microfiber) has a specification of 300D / 576F, and the polyester filament has a specification of 300D / 96F. The ratio of polyester fiber to polyester filament is 2:1. This further reduces water stains after cleaning with the roller brush 1, provides better abrasion resistance, and has a longer service life, eliminating the need for frequent replacement of the roller brush 1.

[0043] In some embodiments, such as Figure 2 and Figure 4As shown, the brush shaft 11 has a mating cavity 111 for connection with the drive motor 4. The mating cavity 111 extends along the axial direction of the brush shaft 11, and its cross-section is cross-shaped, meaning that the cross-sectional profile of the mating cavity 111 along the axis orthogonal to the roller brush 1 is cross-shaped. When the roller brush 1 is assembled onto the cleaning head, the drive head 41 of the drive motor 4 is coaxially connected to the mating cavity 111 to drive the roller brush 1 to rotate. Because the cross-section of the mating cavity 111 is cross-shaped, it can restrict the rotation of the mating cavity 111 relative to the drive head 41, and make the torsional force on the brush shaft 11 evenly distributed. Furthermore, the structure is simple and easy to assemble.

[0044] Optionally, such as Figure 4 As shown, a hollow layer is provided between the inner wall of the mating cavity 111 and the outer wall of the brush shaft 11, and a reinforcing rib 112 is provided within the hollow layer. It can be understood that the hollow structure between the inner wall of the mating cavity 111 and the outer wall of the brush shaft 11 reduces the overall weight of the roller brush 1, decreases energy consumption, and lowers production costs. Because the reinforcing ribs 112 are provided within the hollow layer, and these ribs can be staggered within the hollow layer, the structural strength of the brush shaft 11 is improved, reducing the probability of the roller brush 1 being damaged by impacts.

[0045] like Figures 1 to 3 As shown, another embodiment of the cleaning head of this utility model includes a roller brush 1 and a housing 2. The roller brush 1 is the roller brush 1 of this utility model. The roller brush 1 is mounted on the housing 2. The housing 2 is provided with a dust suction channel 21. The dust suction channel 21 has a dust suction port 211. The dust suction port 211 is arranged opposite to the roller brush 1 along the front-back direction of the housing 2.

[0046] like Figure 2 As shown, the roller brush 1 is located on the front side of the housing 2, and the suction port 211 of the suction channel 21 is arranged facing the front side of the housing 2 and is arranged opposite to the brush bristle surface of the roller brush 1.

[0047] Optionally, such as Figure 3 As shown, the cleaning head also includes a scraper 3, which is installed on the upper edge of the suction port 211. The distance from which the scraper 3 extends into the pile layer 121 is M, where 4mm ≤ M ≤ 6mm. In other words, the interference fit between the scraper 3 and the pile layer 121 is M, which can be selected between 4mm and 6mm. By selecting the interference fit between the scraper 3 and the pile layer 121 within the above range, the cleaning head of this embodiment of the present invention can ensure the sealing between the roller brush 1 and the scraper 3, so that the dirt swept by the roller brush 1 can smoothly enter the suction channel 21. On the other hand, it can reduce the water stains remaining after the roller brush 1 cleans, and reduce the wear on the pile layer 121, resulting in a longer service life.

[0048] For example, M can be 4mm, 4.2mm, 4.4mm, 4.6mm, 4.8mm, 5mm, 5.2mm, 5.4mm, 5.6mm, 5.8mm, or 6mm.

[0049] Optionally, such as Figure 3 As shown, the scraper 3 includes a fixed section 31 and a dirt-blocking section 32. The fixed section 31 is connected to the housing 2, and the dirt-blocking section 32 is connected to the fixed section 31. The dirt-blocking section 32 extends downward at an angle toward the roller brush 1 and extends into the pile layer 121. Because the dirt-blocking section 32 extends downward at an angle toward the roller brush 1, it can remove dirt attached to the roller brush 1. Under the negative pressure of the suction channel 21, the dirt can be sucked into the suction channel 21 to clean the roller brush 1.

[0050] For example, the scraper 3 is a metal plate structure, which can improve the wear resistance of the scraper 3. The fixing section 31 of the scraper 3 extends into the housing 2 by a certain distance to improve the firmness of the scraper 3 installation.

[0051] In one example, such as Figure 2 and Figure 3 As shown, the baffle section 32 is located above the axis of the roller brush 1, and the baffle section 32 extends downward at an angle in the direction toward the axis of the roller brush 1. It can be understood that in a cross-section orthogonal to the axis of the roller brush 1, the extension line of the baffle generally passes through the center of the roller brush 1, thereby making the cleaning effect of the scraper 3 better.

[0052] Another embodiment of the cleaning device of this utility model includes the cleaning head of this utility model. The technical advantages of the cleaning device of this utility model embodiment are the same as those of the roller brush 1 and the cleaning head of the above embodiments, and will not be repeated here.
