Description

TECHNICAL FIELD

[0001] The application provides a cleaning brush assembly and a cleaning device, and relates to the technical field of cleaning devices. In particular, it relates to a cleaning brush scraper and a cleaning brush. The application claims priority to the Chinese patent application No. 2024223904917, filed on September 29, 2024, and entitled "Cleaning brush assembly and cleaning device", the contents of which are hereby incorporated by reference in its entirety. BACKGROUND

[0002] Generally, a vacuum cleaner can be used to suck up dust, debris, hair and other garbage on the ground, which can meet the daily household cleaning needs of people. However, in daily life, sometimes there are water stains on the ground, and the traditional vacuum cleaner cannot clean the position with water stains well.

[0003] In order to solve the above technical problems, a scrubber or a mop can be used to handle the ground with water stains. However, the scrubber and the mop cannot handle dry dust and debris well, are relatively troublesome to use, and the scrubber is relatively expensive and cannot be universally applied to ordinary families.

[0004] The existing scrubber usually sucks the water squeezed out of the brush cloth by the scraper in the brush cloth of the vacuum motor into the sewage tank. However, for the brush assembly of the vacuum cleaner, the vacuum motor cannot be configured due to space limitations. When there is no suction force, the water squeezed out of the brush cloth by the scraper is difficult to move away from the brush cloth, and eventually leaks from the outside of the sewage tank inlet, forming a water stain on the ground, which seriously affects the cleaning effect. CONTENT OF THE INVENTION

[0005] Therefore, the embodiments of the application provide a cleaning brush scraper and a cleaning device to improve the problem of leakage of sewage in the cleaning brush assembly in the background art.

The preferred embodiments of the present application are described as follows, however, in addition to these detailed descriptions, the present application can have other implementation manners.

[0046] The embodiment of the present application provides a cleaning floor brush 100, as shown in Figure 1 、 Figure 2 The cleaning floor brush 100 includes a rolling brush 2, a sewage tank 3 and a cleaning floor brush scraper for scraping sewage on the rolling brush 2. The function of the scraper is to squeeze out the sewage in the brush cloth 21 through the extrusion force between the rolling brush 2 and the brush cloth 21 when the rolling brush 2 rolls, so that the sewage in the brush cloth 21 finally flows into the sewage tank 3 along the inlet of the sewage tank. As shown in Figure 3 The cleaning floor brush scraper includes: a scraper main body 1, the scraper main body 1 includes a front section 11 and a rear section 12, combinedFigure 2 As shown in the figure, the front section 11 abuts against the brush cloth 21 of the cleaning floor brush roll brush 2 to squeeze out the moisture in the brush cloth 21, and the rear section 12 is at least partially located outside the brush cloth 21, one end of the rear section 12 is connected with the front section 11, and the other end is configured to extend towards the inlet of the cleaning floor brush sewage tank 3.

[0047] Taking the direction away from the ground when the roll brush 2 contacts the ground as the height direction and the direction parallel to the ground as the horizontal direction, as shown in the figure, Figure 3 As shown in the figure, the lower surface of the front section 11 can be a curved surface, the height of the lower surface of the front section 11 gradually increases in the direction away from the brush cloth 21, the included angle between the straight line connecting the lowest point and the highest point of the lower surface of the front section 11 and the horizontal direction is between 20° and 30°, and the highest point of the lower surface of the front section 11 is flush with the highest point of the lower surface of the rear section 12.

[0048] In an optional embodiment, as shown in the figure, Figure 3 As shown in the figure, the lower surface of the rear section 12 is a curved surface, which can ensure smooth flow of sewage and avoid the problem of sewage blockage or leakage caused by poor sewage drainage effect. The height of the lower surface of the rear section 12 gradually decreases in the direction away from the brush cloth 21, the included angle between the straight line connecting the lowest point and the highest point of the lower surface of the rear section 12 and the horizontal direction is between 7° and 13°, and the highest point of the lower surface of the front section is smoothly connected with the highest point of the lower surface of the rear section. It can be understood that the lower surface of the rear section 12 can also be a plane, which can also effectively drain sewage.

[0049] In an optional embodiment, the rolling direction of the contact point between the brush cloth 21 and the edge of the front section 11 is the first direction, the included angle between the tangent direction of the lower surface of the front section 11 and the first direction is α, and α gradually increases in the direction away from the brush cloth 21.

[0050] The cleaning floor brush scraper and the cleaning floor brush provided by the embodiment can guide the squeezed sewage on the brush cloth 21 of the roll brush 2 by the shape and structure of the lower surface of the front section 11 of the scraper main body 1, as shown in the figure, Figure 4 As shown in the figure, the moisture in the brush cloth 21 has a certain kinetic energy, and the separated sewage can flow along the lower surface of the front section 11 and gradually move away from the brush cloth 21, then enter the inlet of the sewage tank 3 along the rear section 12, and finally smoothly enter the sewage tank 3. Therefore, the cleaning floor brush scraper and the cleaning floor brush provided by the embodiment can significantly improve the problem of sewage leakage at the inlet of the sewage tank 3.

[0051] The principle that the sewage can flow along the lower surface of the front section 11 and gradually move away from the brush cloth 21 is that the rolling direction of the contact point between the brush cloth 21 and the edge of the front section 11 is the first direction, and the included angle between the tangent direction of the lower surface of the front section 11 and the first direction is α, as shown in the figure, Figure 4 As shown in the figure, the moisture in the brush cloth 21 is squeezed out to form a sewage flow at the moment when the brush cloth 21 is squeezed by the front section 11, Figure 4As shown, the instantaneous movement direction of the sewage flow should be along the first direction, and the direction of the sewage flow is quickly deflected by an angle of α under the guidance of the arc-shaped surface of the lower surface of the front section 11, and then continues to flow along the lower surface of the front section 11 under the action of inertia.

[0052] In an optional embodiment, since the lower surface of the front section 11 is gradually increased in the direction away from the brush cloth 21, the speed of the sewage flow deviating from the original movement direction is gradually increased, that is, the speed of the water flow away from the brush cloth 21 is accelerated, so that the water flow is easy to separate from the brush cloth 21 before the kinetic energy is exhausted, and smoothly flows to the rear section 12. Since the height of the lower surface of the rear section 12 is gradually reduced in the direction away from the brush cloth 21, the sewage flow is finally easy to enter the sewage tank 3 along the rear section 12.

[0053] In an optional embodiment, the minimum value of α is in the range of 0°-60°, and the guiding effect on the sewage extrusion instant is obvious at this angle.

[0054] In an optional embodiment, as shown in Figures 5-7 The cleaning floor brush scraper further includes a water blocking strip 4 located on both sides of the scraper main body 1, and the water blocking strip 4 protrudes from the lower surface of the scraper main body 1. In this embodiment, the position of the water blocking strip 4 corresponds to the position of the two sides of the roller brush 2, so as to prevent the water extruded from the edge of the brush cloth 21 on the roller brush 2 from leaking from the two sides of the roller brush 2 and failing to be collected by the sewage tank 3.

[0055] In an optional embodiment, as shown in Figure 6 In the direction away from the brush cloth 21, the water blocking strips 4 on both sides of the scraper main body 1 gradually move closer to each other along the axial direction of the roller brush 2. In this embodiment, as shown in Figure 6 The water blocking strips 4 on both sides of the scraper main body 1 are in a gradually closing state, which can improve the problem of sewage leakage caused by the sewage flow at the edge of the scraper main body 1 falling outside the inlet of the sewage tank 3 when the sewage flow on the brush cloth 21 flows from front to back along the lower surface of the scraper main body 1.

[0056] In an optional embodiment, as shown in Figure 5 The cleaning floor brush scraper further includes a water blocking strip 4 located on both sides of the scraper main body 1, and the water blocking strip 4 protrudes from the lower surface of the scraper main body 1. In this embodiment, the position of the water blocking strip 4 corresponds to the position of the two sides of the roller brush 2, so as to prevent the water extruded from the edge of the brush cloth 21 on the roller brush 2 from leaking from the two sides of the roller brush 2 and failing to be collected by the sewage tank 3. Figure 8 As shown in Figure 9 The upper surface of the water blocking strip 5 forms a flow guiding surface 51 capable of guiding the water flow, and the flow guiding surface 51 is connected with the upper surface of the front section 11. Figure 9As shown, the cleaning floor brush 100 further comprises a mounting top plate 6 and a sealing strip 7, the squeegee body 1 is fixed below the mounting top plate 6, and the sealing strip 7 is located between the mounting top plate 6 and the upper surface of the front section 11; due to the actual installation needs, the length of the sealing strip 7 is generally less than the length of the upper surface of the front section 11 along the axial direction of the roller brush 2. Under this structure, there will also be liquid retention between the mounting top plate 6 and the upper surface of the front section 11 during the actual use of the cleaning floor brush 100. These liquids can come from the sewage remaining on the brush cloth 21, or from the clean water that has not been fully absorbed by the brush cloth 21. Therefore, there is a situation of seepage liquid at the gap at both ends of the sealing strip 7, and therefore the gap position is designed to be aligned with the drainage surface 51, so that the seepage sewage or clean water can flow along the drainage surface 51 into the inlet of the sewage tank 3, and the liquid at this position is recycled, thereby improving the problem of liquid seepage.

[0057] In an optional embodiment, as shown in Figure 8 The front section 11 has a comb tooth 111 near one end edge of the brush cloth 21. In this embodiment, the comb tooth 111 can be provided to facilitate the trapping of debris or hair adhered to the brush cloth 21, thereby avoiding the problem of difficult cleaning of the brush cloth 21.

[0058] In an optional embodiment, as shown in Figure 3 When the roller brush 2 contacts the ground, the length of the front section 11 in the horizontal direction is 3 mm, the height of the front section 11 in the vertical direction is 1.4 mm, the length of the rear section 12 in the horizontal direction is 29 mm, and the height of the rear section 12 in the vertical direction is 4.6 mm. In this embodiment, through the design of the dimensions, it has been measured that the effect of preventing sewage leakage is good.

[0059] In an optional embodiment, as shown in Figure 2 The inlet of the sewage tank 3 comprises a guide table 31, and the guide table 31 is located below the rear section 12; one side edge of the guide table 31 is adjacent to the surface of the brush cloth 21, and the height of the upper surface of the guide table 31 gradually decreases in the direction away from the brush cloth 21. In this embodiment, the edge of the guide table 31 is adjacent to the surface of the brush cloth 21, so that the sewage separated from the brush cloth 21 can more easily fall into the receiving range of the guide table 31 during the falling process, so that the sewage can smoothly enter the sewage tank 3.

[0060] It should be understood that the above embodiments are exemplary and are not intended to include all possible implementations encompassed by the claims. Various modifications and changes can also be made to the above embodiments without departing from the scope of the present disclosure. Similarly, any combination of the technical features of the above embodiments can also be made to form additional embodiments of the present application that have not been explicitly described. Therefore, the above embodiments only express several implementation manners of the present application, and do not limit the protection scope of the patent of the present application.
