[0025] The water guide connector 100 has two parallel water inlet connectors 110 and two parallel water outlet connectors 120. Each water inlet connector 110 and each water outlet connector 120 are connected to each other to guide water. The water inlet connector 110 is connected to the water supply hose (not shown in the figure) in the windshield washer fluid blade. A groove 140 is provided on each side of the water guide connector 100, and a groove 150 is provided on the top of the water guide connector 100. A groove edge 151 is provided at the bottom of the groove 150.

[0026] The fluid element 200 has two parallel fluid channels inside (not shown in the figure). At the same time, a pair of clamps 210 and a pair of clamps 220 are formed at both ends of the fluid element 200. A clamp channel is provided in each clamp 210 and 220. One end of the clamp channel in each clamp 210 is connected to one end of each fluid channel, and one end of the clamp channel in each clamp 220 is connected to the other end of each fluid channel.

[0027] A connector 211 is provided on each clamp 210, and the connector 211 communicates with the clamp flow channel in the clamp 210; a connector 221 is provided on each clamp 220, and the connector 221 communicates with the clamp flow channel in the clamp 220. In use, a pair of connectors 211 are inserted into a pair of flow channels of the baffle 710, and a pair of connectors 221 are inserted into a pair of flow channels of the baffle 720, to supply water to the flow channels of the pair of baffles 710 and 720.

[0028] A pair of water inlet holes 230 are provided at one end of the fluid element 200, and the pair of water inlet holes 230 are respectively connected to one end of a pair of fluid flow channels inside the fluid element 200. The pair of water inlet holes 230 are used for insertion into a pair of water outlet plugs 120 of the water guide connector 100. A flexible hook 250 extending in the direction of the water guide connector 100 is provided at the top 240 of the fluid element 200.

[0029] The fluid element 200 is mounted on the mounting base 800 of the water-spraying wiper blade; the bottom of the mounting base 800 is fixed to the middle position of the spring 900. In addition, water spray holes 212 and 222 are provided at the ends of a pair of clamps 210 and a pair of clamps 220 to increase the amount of water sprayed in the middle of the water-spraying wiper blade.

[0030] The fluid element 200 is mounted on the fixed base 800 specifically as follows:

[0031] A mounting groove 810 is provided on the fixed base 800, and locking holes 811a are provided on the two sides of the groove 811 of the mounting groove; elastic locking edges 261 are provided on both sides 260 of the fluid element 200. After the fluid element 200 is installed in the mounting groove 810, each elastic locking edge 261 is locked into the corresponding locking hole 811a, preventing the fluid element 20 from coming out of the mounting groove 810.

[0032] In order to hinge the scraper arm 400, a hinge hole 811a is provided on each side of the mounting groove 811. The scraper arm 400 is fixedly connected to the connector (not shown in the figure), and the connector and the fixed seat 800 are hinged in the hinge hole 811a.

[0033] On the two sides 410 of the scraper arm 400, there are claws 411 (the aforementioned first claw) and claws 412 (the aforementioned second claw). The claws are further away from the fluid element 200 than the claws 411.

[0034] During installation, the connectors 211 and 221 of the fluid element 200 are inserted into the flow channels of a pair of baffles 710 and 720, respectively. Then, the pair of baffles 710 and 720 and the pair of scrapers 610 and 620 are mounted on the spring 500. The pair of baffles 710 and 720 and the pair of scrapers 610 and 620 are respectively located at both ends of the fluid element 200. The water supplied to the fluid element 200 by the water guide connector 100 flows into the baffles 710 and 720 through the fluid element 200 and is ejected from the baffles 710 and 720.

[0035] Next, the two outlet connectors 120 of the water-conducting connector 100 are inserted into the two inlet holes 230 of the fluid element 200. During insertion, the elastic hooks 250 on the fluid element 200 gradually pass through the groove 150. After the two outlet connectors 120 of the water-conducting connector 100 are fully inserted into the two inlet holes 230 of the fluid element 200, the elastic hooks 250 on the fluid element 200 hook onto the groove edge 151 of the groove 150, so that the water-conducting connector 100 and the fluid element 200 are tightly connected, preventing the loosening of the connection and leakage caused by vibration, bumps, etc. during actual use.

[0036] The scraper arm 400 is then hinged to the fixed base 800 via a connector, and the claw 411 on the scraper arm 400 is inserted into the groove 140 of the water guide connector 100, so that the water guide connector 100 is mounted on the scraper arm 400. The claw 411 can move up and down in the groove 140, allowing the scraper arm 400 to float during the scraping of the glass.

[0037] During disassembly, lift the scraper arm 400 away from the fixed base 800 in the direction away from the turbulence wing 710. At this time, a pair of claws 412 press against the elastic hook 250 of the fluid element, causing the elastic hook 250 to rotate away from the turbulence wing 710, thereby unlocking the groove edge 151 on the water guide connector 100 from the elastic hook 250 on the fluid element 200.
