[0025] Furthermore, the third side protrusion 5 is located on the top of the second side protrusion 4, and an "L"-shaped groove is provided on the opposite side of the third side protrusion 5 and the second side protrusion 4.

[0026] Furthermore, a cleaning protrusion 6 is provided on the top of the rubber strip main body 1, and the third side protrusion 5 is located on the left and right sides of the bottom of the cleaning protrusion 6 and is connected thereto.

[0027] Furthermore, a hollow anti-deformation embedded part 11 is installed inside the installation protrusion 8, the hollow anti-deformation embedded part 11 is located outside the water spraying channel 2, and a through hole communicating with the water spraying hole 7 and the water spraying channel 2 is opened on the hollow anti-deformation embedded part 11.

[0028] Furthermore, the material of the hollow anti-deformation embedded part 11 is nylon.

[0029] Furthermore, a protective coating 10 is coated on the surfaces of the first side protrusion 3, the second side protrusion 4, the third side protrusion 5 and the cleaning protrusion 6, and the material of the protective coating 10 is a Teflon coating.

[0030] Furthermore, hollow elastic support members 9 are fixedly connected to both the left and right sides inside the rubber strip main body 1, and the tops of the hollow elastic support members 9 are located at the bottom of the cleaning protrusion 6.

[0031] The wiper rubber strip is integrally installed in the wiper frame. The cleaning liquid system of the vehicle is installed on the cover of the wiper frame through a pipeline and is connected to the water spraying channel 2 on the wiper rubber strip. The cleaning liquid can enter the water spraying holes 7 through the water spraying channel 2, and the water spraying holes 7 evenly spray the cleaning liquid on the windshield, so that the wiper can more effectively remove dirt and residues during wiping.

[0032] During use, the cleaning protrusion 6 fits with the glass surface to clean the dirt and rainwater on the glass surface. The third side protrusion 5 guides the rainwater cleaned by the cleaning protrusion 6. The second side protrusion 4 and the first side protrusion 3 conduct secondary cleaning on the rainwater cleaned from the glass surface and also clean the sundries and snow accumulated on the glass surface. The installation protrusion 8 evenly distributes the pressure applied by the wiper arm over the entire length of the rubber strip, ensuring that the wiper can closely fit the glass surface during wiping and improving the cleaning effect. The hollow anti-deformation embedded part 11 is installed inside the installation protrusion 8 to strengthen its structure and prevent the service strength of the installation protrusion 8 from being reduced due to the opening of the water spraying channel 2.

[0033] By setting the protective coating 10, the friction between the wiper rubber strip and the glass surface can be significantly reduced. This not only reduces the resistance during the wiping process of the wiper but also reduces the wear of the rubber strip and extends the service life of the wiper. Due to the non-adhesive property of the Teflon coating, rainwater and dirt are more easily pushed away by the wiper and will not form residues on the glass surface. This helps to improve the cleaning effect of the wiper and keep the field of vision clear.

[0034] By setting the hollow elastic support 9, the service strength of the cleaning protrusion 6 can be increased, improving its cleaning effect on stubborn stains. Moreover, the middle and bottom of the hollow elastic support 9 are located inside the rubber strip main body 1, which can strengthen the strength inside the rubber strip main body 1.

[0035] The above are only the preferred embodiments of the present utility model and are not intended to limit the present utility model. Any modifications, equivalent replacements, and improvements made within the spirit and principle of the present utility model shall be included within the protection scope of the present utility model.
