Description

Technical Field

[0001] This utility model relates to the field of water-spray wiper blade technology, and in particular to a split-type flow channel component for water-spray wiper blades. Background Technology

[0002] Most windshield wiper nozzles on the market are located under the hood or on the wiper arm. When located under the hood, the nozzle sprays water that can obstruct the driver's view, and the water spray is uneven and the volume is large. When located on the wiper arm, the angle of the nozzle spraying water changes with the movement of the wiper arm, and it cannot effectively cover the entire wiping area.

[0003] Currently, some windshield washer blades integrate the mounting base and fluid element into a single component, serving as both a wiper arm adapter and a water guide; however, this integration makes it difficult to freely adjust the position of the spoiler channel. Other designs, especially for bidirectional washer blades, separate the mounting base and fluid element into individual parts before assembly. Furthermore, both methods, integrating the mounting base and fluid element into a single part and separating them before assembly, result in more complex molds for the mounting base. Utility Model Content

[0004] The technical problem to be solved by this utility model is to provide a split flow channel component for windshield spray wipers that allows for free adjustment of the position of the spoiler flow channel and has a relatively complex fixed base mold, which addresses the problems of existing windshield spray wiper blades.

[0005] The technical problem to be solved by this utility model can be achieved through the following technical solution:

The inlet-side plug is also provided with an inlet connector, which is connected to the water supply component in the windshield washer blade. The water supply component supplies water to the inlet-side plug and supplies water to the first spoiler through the inlet-side plug, which sprays out from the first spray hole of the first spoiler. At the same time, it supplies water to the second spoiler through the first flow channel and the outlet-side plug, which sprays out from the second spray hole of the second spoiler.

[0010] In a preferred embodiment of the present invention, the water inlet side plug has a second flow channel inside and a first connector is also provided on the water inlet side plug. The first connector and the water inlet connector are connected to the second flow channel, and the first connector is inserted into one end of the first flow channel of the plug.

[0012] In a preferred embodiment of the present invention, a third water spray hole is provided at the end of each first clamping foot. The third water spray hole is connected to the third flow channel, so that water in the third flow channel is sprayed out from the third water spray hole.

[0013] In a preferred embodiment of the present invention, a pair of first clamps arranged in a figure-eight shape clamp the first spoiler wing.

[0014] In a preferred embodiment of the present invention, the outlet side plug has a fifth flow channel inside and a second connector is provided on the outlet side plug. The second connector communicates with the first flow channel and is inserted into the other end of the first flow channel of the plug.

[0015] In a preferred embodiment of this utility model, a pair of second clamps arranged in a figure-eight shape are provided on the water outlet side plug. A sixth flow channel is provided in each second clamp and a third connector is provided at the end of each clamp. The sixth flow channel is connected to the fifth flow channel, and the third connector is connected to the sixth flow channel. The third connector is inserted into the seventh flow channel of the second baffle, and the second water spray hole of the second baffle is connected to the seventh flow channel.

[0016] In a preferred embodiment of the present invention, a fourth water spray hole is provided at the end of each second clamping foot. The fourth water spray hole is connected to the sixth flow channel, so that water in the third flow channel is sprayed out from the fourth water spray hole.

[0017] In a preferred embodiment of the present invention, a pair of second clamps arranged in a figure-eight shape clamp the second spoiler wing.

[0018] In a preferred embodiment of this utility model, a baffle rib and a hook rib are provided at the top of the slot; a stop block is provided at the top of the insert, the stop block cooperating with the baffle rib to restrict the movement of the insert in a first direction; a hook is provided on the water inlet side insert, the hook hooking onto the hook rib to restrict the movement of the insert in a second direction; the first direction is opposite to the second direction; the baffle rib and hook rib are used to restrict the movement of the insert in a third direction, the bottom of the insert and the bottom of the slot are used to restrict the movement of the insert in a fourth direction, the third direction is opposite to the fourth direction; the two sides of the slot restrict the movement of the insert in a fifth and sixth direction, the fifth direction is opposite to the sixth direction; the first and second directions are perpendicular to the third and fourth directions, and the fifth and sixth directions are perpendicular to each other.

[0019] In a preferred embodiment of the present invention, the second connector and the third connector are connected to the two ends of the first flow channel of the plug-in through elastic deformation.

[0020] Because of the above technical solution, the split-type flow channel component for the water-spraying wiper blade of this utility model is manufactured separately from the fixed base, eliminating the need to form the water channel, inlet pipe, and outlet pipe on the fixed base, thus simplifying the mold for forming the fixed base. Secondly, the inlet-side and outlet-side inserts, which connect to the first and second spoilers, are manufactured separately and then inserted into each other. This allows for free adjustment of the positions of the flow channels of the first and second spoilers to adapt to the inlet-side and outlet-side inserts. Attached Figure Description
