After the weight is removed, the second connecting end 812 serves as a fulcrum, the first connecting end 811 moves upward, the weighing cover plate 30 resets, and is ready for the next weighing.

[0063] In some other embodiments, the distance between the drainage portion 22 and the bottom disc 10 gradually decreases from the middle of the drainage portion 22 to the opposite sides of the drainage portion 22.

[0064] Specifically, after the liquid flows into the drainage groove 221, due to the fact that the drainage portion 22 is inclined downward from the middle of the drainage portion 22 to the opposite sides of the drainage portion 22, the liquid flows from the middle to the sides in the drainage groove 221 under the action of gravity, until the liquid flows out of the outside, so as to avoid the accumulation of the liquid in the drainage groove 221.

[0065] Finally, it should be noted that: the above examples are used to illustrate the technical solutions of the present application, rather than limiting them; under the idea of the present application, the technical features in the above examples or different examples can also be combined, the steps can be implemented in any order, and there are many other changes of the different parts of the present application as described above, in order to be simple, they are not provided in details; although the present application has been described in detail with reference to the foregoing examples, those skilled in the art should understand that: it can still modify the technical solutions recorded in the foregoing examples, or make equivalent replacement for part of the technical features; and these modifications or replacements do not make the essence of the corresponding technical solutions deviate from the scope of the technical solutions of the embodiments of the present application.
