In some embodiments, the step 192b has a first face 1921b, a stepped face 1922b, an inclined face 1923b, and a second face 1924b connected in sequence.

Wherein, the first surface 1921b is located on the inner circle of the step 192b, that is, the first surface 1921b is located on the inner surface of the step 192b, and the first surface 1921b is close to the sink table 191b.

The step surface 1922b is located at the free end of the step 192b, or is located at the top of the step 192b. The stepped surface 1922b can be perpendicular to the first surface 1921b or the second surface 1924b, and the stepped surface 1922b can be parallel to the surface of the sink 191b.

In some embodiments, the difference between FIGS. 12-14 and FIGS. 8-11 is that the height of the step 192b is smaller than the height of the step 192a. Specifically, please refer to FIG. 15 , which is an enlarged view of D in FIG. 14 . The range of the height H2 of the step 192a may be greater than 0.03mm and less than 0.1mm, that is, 0.03mm<H2<0.1mm, and further, the 0.06mm<H2<0.08mm.
