At the same time, the concealed structure also plays a certain protective role for the liquid outlet pipe of the cover seat, avoiding the phenomenon of being hit by foreign objects when the liquid outlet pipe of the cover seat is in the concealed state, thereby extending its service life. In addition, the liquid outlet pipe of the cover seat can be switched between the use state and the concealed state, and is easy to use.

[0034] In some embodiments, the concealing structure 3 is configured to conceal the entire liquid outlet pipe 2 of the cover base, or the concealing structure 3 is configured to conceal a portion of the liquid outlet pipe 2 of the cover base.

[0035] like Figure 1-28 As shown in Figures 32-36, 40, 41, 45 and 46, in order to better accommodate the concealed cover base liquid outlet pipe, the concealed structure 3 includes a concealed groove provided on the cover base 1 for concealing the cover base liquid outlet pipe 2 in a concealed state.

[0036] like Figures 29-31 As shown in Figures 37-39, the concealed structure 3 is formed by the inner side of the cover seat 1. When the cover seat liquid outlet pipe 2 is in a concealed state, the cover seat liquid outlet pipe 2 is located on the inner side of the cover seat 1.

[0037] like Figure 1-41 As shown, for ease of use, the lower portion of the cover base liquid outlet pipe 2 is connected to the cover base 1 via a connecting portion 20 so that the cover base liquid outlet pipe 2 can move relative to the cover base 1, thereby enabling the cover base liquid outlet pipe 2 to be switched between a use state and a concealed state.
