Description

Technical Field

[0001] This utility model relates to the field of windshield washer blade technology, and in particular to a snap-fit ​​with a one-way valve for windshield washer blades. Background Technology

[0002] Most commercially available washer wiper blades or wiper arms use a clip on the arm to secure the water hose to the wiper arm. However, this requires an additional one-way valve for backflow prevention. The one-way valve and clip are separate components, making installation more complicated. Utility Model Content

[0003] The technical problem to be solved by this utility model is to provide an integrated buckle with a one-way valve for windshield washer blades, which reduces assembly steps and improves assembly efficiency, addressing the problem of multiple installation steps caused by the separate design of the one-way valve and the buckle in existing windshield washer blades or windshield washer arms.

[0004] The technical problem to be solved by this utility model can be achieved through the following technical solution:

[0005] A snap-fit ​​with a one-way valve for a windshield washer blade, comprising a snap-fit ​​and a one-way valve, characterized in that the snap-fit ​​is integrated with the one-way valve, the snap-fit ​​is snapped onto the arm of the wiper arm, the one-way valve has at least two nozzles, at least one nozzle is connected to a water pump via an inlet pipe, and at least one nozzle is connected to an inlet nozzle on a wiper blade mounting base via an outlet pipe.

[0006] In a preferred embodiment of the present invention, the buckle has a locking part that locks onto the arm of the scraper arm, and the one-way valve is integrated into the side of the locking part that faces away from the arm of the scraper arm.

[0007] By adopting the above technical solution, this utility model integrates the buckle and the one-way valve together, saving assembly steps and improving assembly efficiency. Attached Figure Description

[0011] Figure 4 for Figure 1 Enlarged schematic diagram at point I. Detailed Implementation

[0012] The present invention will be further described below with reference to the accompanying drawings and specific embodiments.

[0013] See Figures 1 to 4 The figure shows a snap-fit ​​device with a one-way valve for a windshield washer blade, comprising a snap-fit ​​10 and a one-way valve 20. The snap-fit ​​10 has an engaging portion 11 that snaps onto the arm 31 of the wiper arm 30. The one-way valve 20 is integrated on the side 11a of the engaging portion 11 facing away from the arm 31 of the wiper arm 30. The one-way valve 20 has two nozzles 21 and 22. One nozzle 21 is connected to a water pump via an inlet pipe 41, and the other nozzle 22 is connected to an inlet nozzle (not shown in the figure) on the wiper blade holder 50 via an outlet pipe 42.

[0014] The scraper arm 30 is connected to the fixed base 50 via the connector 60. The fixed base 50 is connected to the spoiler 70. The scraper blade 80 is mounted on the fixed base 50 and the spoiler 70. The spoiler 70 is provided with a water spray hole 71.

Claims

1. A clip with a one-way valve for a windshield washer blade, comprising a clip and a one-way valve, characterized in that, The buckle is integrated with the one-way valve and is snapped onto the arm of the scraper. The one-way valve has at least two water nozzles, at least one of which is connected to the water pump via an inlet pipe, and at least one of which is connected to the inlet nozzle on the scraper mounting seat via an outlet pipe.

2. A snap-fit ​​with a one-way valve for a windshield washer blade according to claim 1, characterized in that, The buckle has an engaging portion that engages with the arm of the scraper arm, and the one-way valve is integrated into the side of the engaging portion that faces away from the arm of the scraper arm.
