At the same time, the downward movement of the sliding tube drives the baffle to move downward and release the closure of the slag discharge pipe, and the scraped sediment is discharged through the slag discharge pipe, so as to prevent the sediment from remaining in the purification box and affecting the subsequent purification effect. At the same time, the U-shaped limit rod is reset under the action of the telescopic elastic rod two to re-limit the scraper, thereby reducing the subsequent maintenance cost and improving the slag discharge effect.

[0017] (3) In this high-efficiency portable water desalination device, the connecting rod moves up and down through the block to drive the screw rod and the receiving block to rotate, and under the action of the tooth block 1 and the tooth block 2, the rotating plate and the guide plate are driven to rotate. The guide plate rotates to stir the water inside the purification box and improve the efficiency of sediment discharge, thereby preventing the sediment from remaining inside the purification box and re-attaching to the surface of the filter element under the action of subsequent water flow. At the same time, under the action of the limit groove and the limit plate, the guide plate can always rotate during the slag discharge process, thereby improving the slag discharge effect on the sediment.
