[0022] To make the purpose, technical solutions and advantages of the embodiments of the present application clearer, the technical solutions in the embodiments of the present application will be described clearly and completely below in conjunction with the accompanying drawings. Obviously, the described embodiments are only part of the embodiments of the present application, not all of the embodiments.

[0023] Therefore, the following detailed description of the embodiments of the present application is not intended to limit the scope of the present application for protection, but merely represents some embodiments of the present application. Based on the embodiments in the present application, all other embodiments obtained by ordinary technicians in this field without making any creative work are within the scope of protection of this application.

[0024] Example

[0025] See also Figure 1 and Figure 2 The present embodiment provides a cleaning brush for automatic rotating scrubbing, comprising a brush body 1, a handle 2 and bristles 3. A liquid conducting chamber 4 is provided inside the brush body 1. The handle 2 and the brush body 1 are rotationally connected via a bearing 5, that is, the brush body 1 rotates with the handle 2 as the rotation axis via the bearing 5, and the handle 2 remains stationary. A mounting groove 14 is provided in the center of the brush body 1, and the bearing 5 is placed in the mounting groove 14. The axial and planar displacement of the bearing is constrained by the retaining spring 7 and the mounting groove 14. The interior of the handle 2 is hollow and passes through the liquid conducting chamber 4. The liquid conducting chamber 4 also includes a liquid conducting groove 41 and a plurality of liquid outlet holes 42. The liquid outlet holes 42 are distributed at the bottom of the liquid conducting chamber 4. The liquid conducting groove 41 connects the plurality of liquid outlet holes 42 in a spiral form. The bristles 3 are filled into the liquid outlet holes 42 in clusters and are fixedly connected to the brush body 1, as shown in FIG. Figure 3 and Figure 4 As shown. After the handle 2 is connected to the liquid outlet pipe of the cleaning liquid, a high-pressure water column is poured into the liquid guide chamber 4 from the hollow pipe inside the handle 2, and the cleaning liquid accumulates in the liquid guide chamber 4. The liquid guide groove 41 at the bottom of the liquid guide chamber 4 can guide the cleaning liquid to flow in a spiral direction. The cleaning liquid continuously impacts the outer wall of the liquid guide groove 41 to generate a tangential rotational bias force along the spiral direction, thereby driving the brush body 1 to automatically rotate. Compared with traditional brushes, it not only increases the rinsing process in the rotation direction, but also eliminates the need for the operator to spend a lot of effort to scrub the stains back and forth, saving effort while improving cleaning efficiency; the water pressure in the liquid guide chamber 4 prompts the cleaning liquid to flow out along the liquid outlet 42, thereby infiltrating the bristles 3 fixed in the liquid outlet 42. During the process of brushing the glass, the operator does not need to hold the liquid outlet pipe of the cleaning liquid to continuously spray the stains. The operator can hold the handle 2 with both hands to apply force to the brush, which is convenient for the operator to use, reduces the amount of cleaning liquid, and greatly avoids liquid waste.

[0026] In this embodiment, the cleaning brush is further provided with a sealing cover 6. A through hole is provided in the center of the sealing cover 6 for the handle 2 to pass through. The sealing cover 6 is fixedly connected to the brush body 1 on the mounting groove 14 via screws and screw holes. The sealing cover 6 further restricts the axial movement of the bearing 5, preventing external dirt or dust from entering the bearing 5 and interfering with the bearing, thereby improving the rotational stability of the bearing 5. Removing the screws facilitates replacement of the bearing 5.

[0027] Furthermore, the bearing connection end of the handle 2 is further provided with a flange 21, the outer diameter of which is larger than the inner diameter of the bearing 5. The flange 21 enables the handle to be stably overlapped under the bearing 5 without affecting the rotation of the bearing 5, and can be fixed to the brush body 2 by means of the bearing 5, facilitating the assembly and disassembly of the cleaning brush.

[0028] like Figure 2 As shown, in this embodiment, preferably, the brush body 1 includes a rotating plate 11 and a mounting plate 12, which are detachably mounted as a whole via threads. The rotating plate 11 is rotatably connected to the handle 2, and the mounting plate 12 is fixed to the bristles 3. The bristles are a consumable part of the cleaning brush. The brush body 1 is divided into two parts, and the rotating plate 11 and the mounting plate 12 are detachably mounted as a whole via threads. When the bristles are damaged, only the mounting plate 12 assembly needs to be replaced, thereby improving the reuse rate of the cleaning brush.

[0029] Furthermore, the mounting plate 12 protrudes around its periphery to form a protrusion 13, which is fixed to the rotating plate 11. The inner surface of the mounting plate 12 and the protrusion 13, together with the rotating plate 11, form a liquid guide chamber 4. The liquid guide groove 41 and the liquid outlet hole 42 are provided on the mounting plate 12. The liquid guide groove 41 and the liquid outlet hole 42 of the cleaning brush are prone to clogging. Disposing the liquid guide chamber 4 between the rotating plate 11 and the mounting plate 12 facilitates maintenance work such as clearing blockages from the liquid guide groove 41 and the liquid outlet hole 42 within the liquid guide chamber 4.

[0030] Furthermore, a sealing groove 8 is provided between the protrusion 13 and the rotating plate 11, and a sealing strip is provided in the sealing groove 8. The water pressure in the liquid guide chamber 4 is relatively high, and leakage is prone to occur at the joint between the rotating plate 11 and the mounting plate 12. Installing the sealing strip further improves the sealing performance of the liquid guide chamber 4, ensuring that the entire cleaning liquid flows out only from the liquid outlet 42, further saving the amount of cleaning liquid and avoiding waste.

[0031] In addition, the plurality of liquid outlet holes 42 can be distributed at the bottom of the liquid guide chamber 4 in a sparse center and dense periphery arrangement. The water pressure in the center of the liquid guide chamber 4 is higher, while the water pressure in the periphery is lower. The sparse center and dense periphery arrangement can balance the distribution of water pressure, so that the cleaning liquid flows out evenly from each liquid outlet hole 42.

[0032] Preferably, the end of the handle 2 is further provided with an internal thread 22. The thread is connected to the liquid outlet pipe to ensure that the water pressure will not separate the handle 2 and the liquid outlet pipe, thereby improving the convenience of cleaning the brush.
