Description

Technical Field

[0001] This utility model relates to the field of windshield wiper technology, specifically to a water spray assembly and a windshield wiper. Background Technology

[0002] Currently, windshield washer wipers on the market have complex structures and relatively high costs. The most commonly used wipers incorporate at least two machined washer nozzles mounted within the washer assembly. These machined nozzles are expensive, and assembly and adjustment of the spray angle are costly. Furthermore, most washer assemblies include a one-way valve, which consists of a plug, spring, and cap, requiring assembly and further increasing costs. This results in relatively limited market application of windshield washer wipers, primarily found in high-end vehicles. The following issues exist with windshield washer wipers on the market:

[0003] 1. The water spray assembly has a complex structure, including small parts such as one-way valves, which makes assembly difficult and requires additional welding or gluing, resulting in a high cost for the entire water spray assembly.

[0004] 2. The water spray assembly has a complex structure and is more difficult to assemble than the scraper arm and hook plate, making it prone to quality problems.

[0005] 3. Because the water spray angle is adjustable, it needs to be adjusted manually, which is difficult and has high production costs.

[0006] Therefore, there is a need in the art for a water spray assembly and a windshield wiper to solve the above problems. Utility Model Content

[0007] This utility model aims to solve the above-mentioned technical problems by providing a water spray assembly and a windshield wiper.

[0008] To solve the above-mentioned technical problems, the technical solution provided by this utility model is as follows:

[0009] In a first aspect, the present invention provides a windshield wiper spray assembly, including a spray device connected to a wiper hook, the spray device having a water inlet, a water channel and at least two water outlets;

[0010] The inlet is connected to a water channel, and each of the multiple outlets is connected to a connecting passageway between itself and the water channel.

[0011] The water spray device is equipped with a snap-fit ​​structure that works in conjunction with the hook plate.

[0012] In the preferred embodiment of the above-mentioned water spray assembly, the plurality of water outlets are on one side facing the direction of the windshield wiper.

[0013] In the preferred embodiment of the above-mentioned water spray assembly, when there are three sets of water outlets, the water spray directions of the water outlets are respectively the front, rear and middle sections of the wiper.

[0014] In the preferred embodiment of the above-mentioned water spray assembly, the total cross-sectional area of ​​the plurality of connecting channels is not greater than the total cross-sectional area of ​​the water channels.

[0015] In the preferred embodiment of the above-mentioned water spray assembly, the snap-fit ​​structure includes a barb provided on the water spray device, an L-shaped groove is provided on the water spray device, one side of the hook plate is an L-shaped rib structure that can be installed in the L-shaped groove, and a U-shaped groove is provided on the side of the hook plate away from the L-shaped rib structure to cooperate with the barb.

[0016] In the preferred embodiment of the above-mentioned water spraying assembly, the water spraying device is installed on the hook plate and the barb is adapted to the U-shaped groove, and the L-shaped groove is adapted to the L-shaped rib structure.

[0017] In a first aspect, the present invention also provides a windshield wiper that includes the aforementioned water-spraying wiper assembly.

[0018] With the above structure, this utility model has the following advantages:

[0019] This utility model optimizes the structure of the water spraying device. Through the design of water channels, connecting passages and water outlets, it achieves a multi-directional water spraying effect, reduces material and production costs, and lowers the difficulty of manufacturing.

[0020] The assembly structure between the water spray body and the hook plate is optimized by using a snap-fit ​​structure, making the assembly structure simpler and easier to operate.

[0021] The water spray direction has been changed from adjustable to fixed direction. If the design direction is correct, the manual adjustment of the water spray angle can be reduced, thereby reducing production costs and quality problems.

[0033] The present invention will now be described in further detail in conjunction with the full text.

[0034] Combined with appendix Figures 1-5 A water spray assembly includes a water spraying device 2 connected to a hook plate 1. The water spraying device 2 has a water inlet 3, a water channel 11, and at least two water outlets 4. The water inlet 3 is connected to the water channel 11, and each of the multiple water outlets 4 is connected to the water channel 11 by a connecting passageway 5. The water spraying device 2 is equipped with a snap-fit ​​structure for mounting to the hook plate 1. The water spraying device 2 is disposed on the outer surface of the hook plate 1 and connected to the hook plate 1.

[0035] In specific implementation of this utility model, such as Figure 1 and Figure 2 As shown. The total cross-sectional area of ​​the multiple connecting channels 5 is no greater than the total cross-sectional area of ​​the water channels 11. This ensures that the multiple outlets 4 can be filled with water, and the cross-sectional areas of the multiple connecting channels 5 are basically the same, ensuring that the water flow in the three directions is uniform;

[0036] In specific implementation of this utility model, such as Figures 3-5 As shown, the snap-fit ​​structure includes a barb 6 on the water spray device 2, an L-shaped groove 8 on the water spray device 2, an L-shaped rib structure 9 on one side of the hook plate 1 that can be installed in the L-shaped groove 8, and a U-shaped groove 10 on the side of the hook plate 1 away from the L-shaped rib structure 9 that matches the barb 6. The water spray device 2 is mounted on the hook plate 1, with the barb 6 and the U-shaped groove 10 fitting together, and the L-shaped groove 8 and the L-shaped rib structure 9 fitting together. This fixes the water spray device 2 on the hook plate 1, forming upper, lower, and right-direction limits. The L-shaped groove 8 and the L-shaped rib structure cooperate, and these two constraints together limit the water spray device 2, allowing the water spray device 2 to be fixed on the hook plate 1.

[0037] In specific implementation of this utility model, such as Figure 6 As shown, the water spray device 2 has at least two water outlets 4, and multiple water outlets 4 face the side facing the wiper direction. When there are three sets of water outlets 4, the water spraying directions of the water outlets 4 are respectively the front, rear, and middle sections of the wiper. Water is sprayed in different directions, with one water outlet 4 optimally spraying water towards the front half of the wiper and facing the wiper direction; another water outlet 4 optimally spraying water towards the rear half of the wiper and facing the wiper direction; and a third water outlet 4 spraying water towards the middle of the wiper and facing the wiper direction.

[0038] In a specific implementation of this utility model, a windshield wiper includes a water spray assembly, a wiper blade, and a wiper arm. Its function is to remove foreign objects and rainwater from the glass. The wiper blade is mounted on the wiper arm, and the wiper arm drives the wiper blade to brush along the glass in the up-down direction to remove water and stains from the glass. The wiper blade is provided with a bracket for fixing the spring and has an accessory that can rotate around the bracket. The end of the spring is connected to a buckle. The wiper arm is provided with a hook plate and a wiper bar. The hook plate and the wiper bar are connected. The wiper blade is mounted to the hook plate on the wiper arm through the accessory.

[0039] The present invention and its embodiments have been described above. This description is not restrictive, and the embodiments shown throughout the text are only one of the embodiments of the present invention. The actual structure is not limited to this. In conclusion, if a person skilled in the art is inspired by this description and designs a similar structure and embodiment without departing from the inventive spirit of the present invention, such design should fall within the protection scope of the present invention.
