When the first rack 408 is engaged with the first gear 411, that is, when the first gear 411 drives the screen 316 to move, the shutoff plate 507 completely blocks the water outlet pipe 318, and when the engagement between the first rack 408 and the first gear 411 fails, the second through hole 509 is aligned with the water outlet pipe 318.

As a further explanation of the invention, with reference to figure 3,

the first stopper 312 and the second stopper 313 are symmetrically distributed about the axis of the first pin 304.

The present invention makes the second link 311 swing in the same magnitude.

The third stopper 314 and the fourth stopper 315 are symmetrically distributed about the axis of the first pin 304.

As a further explanation of the invention, with reference to figure 5,

the intercepting plate 507 is horizontally disposed.

The intercepting plate 507 is horizontally arranged, so that the intercepting plate 507 can better block the water outlet pipe 318.

The fifth link 504 has a square cross-section.

The cross section of the fifth link 504 is square, so that the fifth link 504 can only move left and right along the first guide rail 505 and cannot move back and forth and rotate.

The above-mentioned embodiments are merely illustrative of the preferred embodiments of the present invention, and do not limit the scope of the present invention, and various modifications and improvements of the technical solution of the present invention by those skilled in the art should fall within the protection scope defined by the claims of the present invention without departing from the spirit of the present invention.
