Figure 9 , Figure 10 and Figure 11The connecting assembly 9 is connected between the slide plate 41 and the sliding block 54, and comprises a first connecting rod 91, a second connecting rod 92, a third connecting rod 93 and a fourth connecting rod 94. One end of the first connecting rod 91 is rotationally connected with the sliding block 54, and the other end of the first connecting rod 91 is slidingly connected with the second connecting rod 92. The end of the second connecting rod 92, which is away from the first connecting rod 91, is rotationally connected with the slide plate 41.

[0071] With reference to Figure 10 and Figure 11 The first connecting rod 91 is internally provided with a sliding cavity 911 for sliding of the second connecting rod 92. The end of the second connecting rod 92, which is located in the sliding cavity 911, is further fixedly provided with a spring piece 921.

[0074] The implementation principle of the embodiment is as follows:

[0075] When the two slide plates 41 are in the abutting state, the spring piece 921 in the sliding cavity 911 generates a spring force on the second connecting rod 92, so that the clamping jaw 922 is clamped in the clamping groove 912. At this time, the first connecting rod 91 and the second connecting rod 92 can be synchronously rotated as a whole. The pull rope 53 is pulled, and the pull rope 53 and the sliding block 54 are synchronously moved upward. The sliding block 54 is moved while driving the first connecting rod 91 to rotate. At this time, the first connecting rod 91 and the second connecting rod 92 are synchronously rotated. The second connecting rod 92 drives the slide plate 41 to slide, and the spring 42 is compressed. In this process, the first connecting rod 91 drives the third connecting rod 93 to rotate, the third connecting rod 93 drives the fourth connecting rod 94 to rotate, and the fourth connecting rod 94 rotates around the hinge point of the water taking member 2, so that the pushing jaw continuously approaches the clamping jaw 922.

[0076] When the sliding block 54 abuts against the sensing block 292, the pulling rope 53 is pulled upward and blocked, at this time, the pulling force of the pulling rope 53 is kept, the two sliding plates 41 lose the blocking of the water inlet 25, and water enters the water storage cavity 23. When the water in the water storage cavity 23 is stored, the pulling force of the pulling rope 53 is continuously increased, the sliding block 54 forces the sensing block 292 to be compressed into the accommodating groove 294, the reset spring 293 is compressed, the push claw pushes the clamping claw 922 to lose the clamping effect with the clamping groove 912, the elastic sheet 921 is compressed, the sliding plate 41 is reset under the elastic force of the spring 42 and re-blocks the water inlet 25.

[0077] The above are preferred embodiments of the present application, which do not limit the protection scope of the present application, and therefore: any equivalent changes made on the structure, shape and principle of the present application should be covered within the protection scope of the present application.
