Description

Technical Field

[0001] This utility model relates to the field of floor scrubber technology, and in particular to an anti-tangling device for floor scrubber brushes. Background Technology

[0002] Most floor scrubbers come with roller brushes, which improve cleaning efficiency during the cleaning process. However, long, thin items such as hair easily get tangled in the roller brush, making it difficult to remove after cleaning and potentially causing the roller brush to jam and damage the machine. A search revealed that the scraper assembly and utility model patent for a floor scrubber (patent number 202322740903.0) use a scraper to remove long, thin items like hair. However, in this design, the scraper's comb teeth are set to be inserted parallel to the bristles of the roller brush, creating significant resistance during operation and making it difficult to quickly scrape off and suck up the long, thin items. To address these issues, this application discloses an anti-tangling device for the floor scrubber brush. Utility Model Content

[0003] To overcome the shortcomings of the existing technology, this utility model discloses an anti-tangling device for floor scrubber brushes.

[0004] To achieve the above objectives, the technical solution adopted by this utility model is as follows: a floor scrubber brush anti-tangling device, comprising an upper brush shell, a lower brush shell, a roller brush, a water spray base, and a scraper. The upper brush shell is fixed above the lower brush shell and forms a dust suction port. The roller brush is rotatably disposed in the dust suction port. The water spray base is fixed to the bottom of the upper brush shell inside the roller brush. The scraper is fixed to the bottom of the water spray base. The front end of the scraper is bent downward at 90° to form a bent portion. A row of comb teeth is provided on the side of the bent portion near the roller brush. The front end of the comb teeth is inclined downward at 145-155° and inserted into the bristles of the roller brush. The tips of the comb teeth are rounded.

[0005] More preferably, the water spray base and the scraper are fixed to the bottom of the floor brush upper shell by two bolts, one above the other.

[0006] More preferably, the water spray base has a row of circular water spray holes on the side facing the roller brush.

[0007] More preferably, the scraper is either a metal scraper or a plastic scraper.

[0008] More preferably, the tips of the comb teeth are tilted downward at an angle of 150°.

[0009] This utility model achieves the following beneficial effects:

[0010] This application utilizes the comb teeth on the scraper to comb the hair tangled on the roller brush during its rotation and suck it into the wastewater tank on the machine. Compared with existing technologies, this reduces scraping resistance, improves scraping efficiency, and has high practical value.

[0011] Other features and advantages of this invention will be set forth in the following description and will be apparent in part from the description, or may be learned by practicing the invention. The objectives and other advantages of this invention can be realized and obtained through the structures pointed out in the description and the accompanying drawings. Attached Figure Description

[0018] Example

[0019] To address the issue of low hair removal efficiency caused by significant resistance encountered by the squeegee assembly in existing floor scrubbers, reference is made to... Figure 1 and Figure 2As shown, this application discloses an anti-tangling device for a floor scrubber brush, including an upper brush shell 10, a lower brush shell 20, a roller brush 30, a water spray base 40, and a scraper 50. The upper brush shell 10 is fixed above the lower brush shell 20 and forms a suction port. The roller brush 30 is rotatably disposed in the suction port. The water spray base 40 is fixed to the bottom of the upper brush shell 10 inside the roller brush 30. The water spray base 40 has a row of circular water spray holes 41 on the side facing the roller brush 30 for spraying water. The scraper 50 is fixed to the bottom of the water spray base 40. The front end of the scraper 50 is bent downward at 90° to form a bent portion 51. A row of comb teeth 52 is formed on the side of the bent portion 51 near the roller brush 30. The front end of the comb teeth 52 is inclined downward at 145-155° and inserted into the bristles of the roller brush 30. The tips of the comb teeth 52 are formed with rounded corner structures 53.

[0020] During operation, the roller brush 30 rotates, and a row of circular water spray holes 41 on the water spray seat 40 spray water toward the roller brush 30. At the same time, the comb teeth 52 on the scraper 50 scrape off hair and other long and thin items on the roller brush 30 and enter the wastewater tank (not shown) in the machine through the suction port.

[0021] To facilitate quick assembly and disassembly of the water spray base 40 and the scraper 50, the water spray base 40 and the scraper 50 of this application are fixed to the bottom of the floor brush upper shell 10 by two bolts 60, one above the other. During the assembly and disassembly process, the operator only needs to remove or tighten the bolts 60.

[0022] In some preferred embodiments, the scraper 50 of this application is either a metal scraper 50 or a plastic scraper 50. In addition, if there are other materials that can meet the requirements for manufacturing the scraper 50 of this application, those skilled in the art can make an appropriate choice accordingly.

[0023] In one exemplary embodiment, the downward tilt angle of the tooth tip of the comb 52 of this application is 150°. Of course, those skilled in the art can also set the angle of the comb 52 to any angle among 145°, 146°, 147°, 148°, 149°, 151°, 152°, 153°, 154°, and 155°.

[0024] Based on the above structure, this application uses the comb teeth 52 on the scraper 50 to comb the hair wrapped around the roller brush 30 during the rotation of the roller brush 30 and suck it into the wastewater tank on the machine through the suction port. Compared with the prior art, it reduces scraping resistance, improves scraping efficiency, and has high application value.
