Description

Technical Field

[0001] The utility model relates to the technical field of water spray wipers, in particular to a nozzle assembly with a one-way valve. Background Art

[0002] In order to wash the vehicle glass, a nozzle is usually added to the wiper to spray washing water through the nozzle to clean the glass. In order to prevent the washing water from flowing back, a one-way valve needs to be added to the nozzle. However, the nozzle with a one-way valve is relatively wide, so that the wiper protrudes more from the glass, increasing the wind resistance of the wiper. Utility Model Content

[0003] The technical problem to be solved by the utility model is to provide a nozzle assembly with a one-way valve of narrow width to reduce the wind resistance of the nozzle in view of the above technical problems caused by the wide water spray width of the existing one-way valve.

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

[0005] A nozzle assembly with a one-way valve comprises a nozzle body, wherein a first water channel connected to a water pipe is arranged in the nozzle body, and the nozzle body is characterized in that a second water channel parallel to the first water channel and a third water channel for connecting the first water channel and the second water channel are also arranged in the nozzle body, a one-way valve is arranged in the second water channel, the one-way valve allows water to flow from the third water channel into the second water channel and prevents water from flowing back from the second water channel to the third water channel; at least one nozzle is arranged on the second water channel.

[0006] In a preferred embodiment of the present utility model, the third water channel and the first water channel, and the third water channel and the second water channel intersect at a certain angle.

[0007] In a preferred embodiment of the present utility model, the angle between the third water channel and the first water channel and the angle between the third water channel and the second water channel are not parallel.

[0008] In a preferred embodiment of the present invention, there are a plurality of nozzles which are arranged at intervals in the length direction of the second water channel.

[0009] In a preferred embodiment of the present invention, adjacent nozzles form an acute angle or a right angle.

[0010] Due to the adoption of the above technical solution, the utility model further provides a second water channel parallel to the first water channel and a third water channel for connecting the first water channel and the second water channel in the nozzle body, and provides a one-way valve in the second water channel, thereby reducing the width of the entire nozzle body and further reducing the wind resistance of the nozzle.

[0015] The present invention is further described below in conjunction with the accompanying drawings and specific implementations.

[0016] See also Figures 1 to 4 A nozzle assembly with a one-way valve shown in the figure includes a nozzle body 10, in which a water channel 11 (the aforementioned first water channel) connected to a water pipe is arranged, and a card slot 12 is arranged on the nozzle body 10, through which the nozzle assembly with a one-way valve is clamped onto the wiper.

[0017] A water channel 13 (the aforementioned second water channel) parallel to the water channel 11 and a water channel 14 (the aforementioned third water channel) for connecting the water channel 11 and the water channel 13 are also provided in the nozzle body 10. The water channel 14 and the water channel 11 and the water channel 14 and the water channel 13 intersect at a certain angle, and the angle between the water channel 14 and the water channel 11 and the angle between the water channel 14 and the water channel 13 are not parallel. For example, the water channel 14 and the water channel 11 and the water channel 14 and the water channel 13 intersect vertically.

[0018] The cleaning water flows into the water channel 13 through the water channels 11 and 14. A one-way valve 20 is arranged in the water channel 13, which allows water to flow from the water channel 14 into the water channel 13 and prevents water from flowing back from the water channel 13 to the water channel 14. The one-way valve 20 is arranged in the water channel 13, and the thickness of the nozzle body 10 can be reduced.

[0019] At least one nozzle 30 is arranged on the water channel 13, for example, three nozzles 30 are arranged, and the three nozzles 30 are arranged in a spaced relationship in the length direction of the water channel 13. Adjacent nozzles 30 form an acute angle or a right angle.
