When the water flows through the integrated sliding water blocking plate 410, it moves up and down through the adjusting column 411. At this time, the adjusting column 411 and the third fixed column 407 form a sliding structure. The sealing plate 412 and the sliding plate 413 on the adjusting column 411 slide up and down in the first adjusting groove 408 and the sliding groove 409 on the inner side of the third fixed column 407. After sliding, the water source will not splash out of the third fixed column 407, and then the water source will flow through the integrated sliding blocking plate 410. After the water plate 410, the water flow impacts the through column 415 and the flip panel 416 installed on the inner side of the second water outlet panel 414. When the water pressure is too high, it impacts the flip panel 416. The water source passes through the filter column 418 in the fourth fixed column 417. The filter column 418 filters impurities from the water source. The fifth fixed column 419 is connected and engaged through the second fixed column 405.

Through the setting of the fifth fixed column 419, the water outlet column 421 can better reduce the water flow.
[0024] Working principle: firstly, connect the external water source, and thread the threaded sleeve 402 and the second threaded tube 403 through the first threaded tube 401, then connect the first threaded tube 401 to the second fixing column 405, and then connect through the second fixing column 405, and then connect with the third fixing column 407 through the first water outlet panel 406. When the water flows through the integrated sliding water blocking plate 410, it moves up and down through the adjusting column 411. At this time, the adjusting column 411 and the third fixing column 407 form a sliding structure, and the sealing plate 412 on the adjusting column 411 and the sliding plate 413 are in the first adjusting plate inside the third fixing column 407. The groove 408 and the sliding groove 409 slide up and down. After sliding, the water source will not splash out at the third fixed column 407. Then, after the water source passes through the integrated sliding water blocking plate 410, the water flow impacts the through column 415 and the flip panel 416 installed on the inner side of the second water outlet panel 414. When the water pressure is too high, the flip panel 416 is impacted. The water source passes through the filter column 418 in the fourth fixed column 417 to filter impurities from the water source. The fifth fixed column 419 is connected and engaged through the second fixed column 405. Then, the fifth fixed column 419 opens a second adjusting groove 420 to adjust the adjusting column 411 up and down, and finally the water flows out through the water outlet column 421.
