Technical Field

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

[0002] Currently, windshield washer fluid wipers on the market have complex structures and high costs. Furthermore, the water spray is mostly in the form of a jet, which has a limited coverage area and often cannot fully cover the brushing area, requiring multiple jets to achieve this. The most common type of windshield washer fluid wiper uses a metal ball head device. The main washer assembly has at least two machined ball heads, which are assembled within the washer fluid unit. Machined ball heads are expensive, and assembly and adjustment of the spray angle are costly. Additionally, most washer fluid units include a one-way valve, which consists of a plug, spring, and cap, requiring assembly and further increasing costs. Therefore, windshield washer fluid wipers are currently less common in the market, mostly found on high-end vehicles. The following problems exist with windshield washer fluid wipers on the market:

[0003] 1. The water spray is in the shape of a water column, which has a small spray range in the brushing area, resulting in the glass not being cleaned properly;

[0004] 2. 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.

[0005] 3. Because most water outlets on the market use metal ball heads, the spray angle needs to be adjusted manually, which is difficult. Utility Model Content
