High-tech cleaning appliances such as vacuum cleaners and floor scrubbers that can provide convenience for daily cleaning, save time and energy have become essential tools for maintaining a clean home environment.

[0003] The cleaning roller brush is a core component of cleaning appliances. The cleaning roller brushes currently used in cleaning appliances on the market can be divided into two types according to whether there are auxiliary materials or not: one is a pure flannel roller brush, and the other is a flannel roller brush assisted by nylon hard silk fabric. Although both the pure flannel roller brush and the flannel roller brush assisted by nylon hard silk fabric can achieve good floor dust removal effects, the above two types of roller brushes have poor dust removal effects in the gaps, and when there is hair on the floor, the roller brush is very easy to entangle and remain on the hair, causing the hair to enter the roller brush bearing of the cleaning appliance, which not only causes the roller brush cleaning effect to deteriorate, but also seriously affects the normal working efficiency of the cleaning appliance, while increasing the difficulty of cleaning the cleaning appliance, and the consumer experience is poor.

[0108] Table 3 Performance test results of the cleaning roller brushes prepared in Example 1 and Comparative Examples 1 to 2

[0109]

[0110] As shown in Table 3, the anti-entanglement efficiency of roller brush 1 in gaps, floors, carpets, and hair is 54.39%, 93.62%, 38.14%, and 44%, respectively; the anti-entanglement efficiency of roller brush 2 in gaps, floors, carpets, and hair is 33.20%, 93.28%, 20.62%, and 46%, respectively; the anti-entanglement efficiency of roller brush 3 in gaps, floors, carpets, and hair is 66.74%, 95.73%, 38.94%, and 66%, respectively. Compared with roller brush 2, roller brush 3 has improved anti-entanglement performance in gaps, floors, carpets, and hair by 33.54%, 2.45%, 18.32%, and 20%, respectively. Compared with roller brush 1, roller brush 3 has improved anti-entanglement performance in gaps, floors, carpets, and hair by 12.35%, 2.11%, 0.8%, and 22%, respectively.

[0111] The calculation method of the hair anti-entanglement efficiency of the roller brush prepared in Example 1, Comparative Example 1 and Comparative Example 2 is as follows: 5g of hair is sucked in normal use, and 2.8g of hair remains on the roller brush, that is, the amount of hair sucked is 5-2.8=2.2g, and the hair anti-entanglement efficiency = (5-2.8) / 5×100% = 44%

[0112] From the above embodiments, it can be seen that the composite cleaning material for the cleaning roller brush provided by the present invention has a TPU composite material added therein. When the roller brush is working, the TPU composite material has both toughness and rigidity. When the roller brush rotates at high speed, it has a stronger shape maintenance ability than the three-dimensional fabric, and the deformation is small, so that it can penetrate deep into the gap and scrape the dust it contacts to the floor surface. It can also achieve an effective "scraping and slapping" effect for the dust in the gap, and then the fluff of the three-dimensional fabric plays a surface cleaning role; at the same time, due to the addition of the TPU composite material, the fluff of the three-dimensional fabric is separated, thereby reducing the density of knotting and entanglement of the hair and the fluff of the three-dimensional fabric, so that the hair on the surface of the roller brush is easier to remove, and the entanglement and retention of the hair on the surface of the roller brush are reduced. In summary, the composite cleaning roller brush provided by the present invention has a significant improvement in the cleaning efficiency of floors, gaps, hair anti-entanglement, etc. It can meet the use needs of customers and enhance the use experience of consumers; at the same time, the composite cleaning roller brush provided by the present invention can be applied to multiple scenes (applicable to floors and carpets at the same time), reducing costs to a certain extent.

[0113] Although the above embodiment describes the present invention in detail, it is only a part of the embodiments of the present invention, not all of the embodiments. Other embodiments can be obtained based on this embodiment without creativity, and these embodiments all fall within the protection scope of the present invention.
