[0027] Working principle: When in use, the rotating cover 201 is pressed to rotate the rotating cover 201, the liquid outlet 3 leaks out, the bottle body 5 is squeezed to make the liquid enter the liquid outlet 3 from the bottle body 5, and the liquid contacts the elastic blocking block 403 and pushes the elastic blocking block 403, so that the elastic blocking block 403 pushes the baffle 402, so that the baffle 402 moves, and then the elastic blocking block 403 is taken out of the through groove 404, and then the liquid impacts the elastic blocking block 403, so that the elastic blocking block 403 pushes the baffle 402 to rotate , so that the liquid can flow out of the liquid outlet 3 normally. After stopping squeezing the bottle body 5, the spring 409 pushes the slide plate 407 to reset, and then pushes the slide bar 406 to reset. The reset of the slide bar 406 pushes the hinge seat 405 to reset, and then drives the baffle 402 to move. After the back of the baffle 402 contacts the inner wall of the limiting groove 4010, the baffle 402 is forced to rotate, and then drives the elastic blocking block 403 to rotate, and squeezes the elastic blocking block 403 into the through groove 404, completing the closure of the liquid outlet 3 to prevent liquid reflux.
