Embodiment 1
[0041] Such as Figure 1-5 As shown, it is an embodiment of the fully automatic closed stage drainage and anti-drying drain of the present invention, wherein the outer chamber 1 is located at the periphery of the drain, the top is open, the bottom is directly connected to the drain pipe 5, and the outer chamber 1 is located at the periphery of the drain. An annular outer frame 2 is arranged on the inner side of the top of chamber 1. The inner core is located inside the outer chamber 1 and is divided into three parts: inner core cover 31, inner core wall 32 and inner core bottom 33. The three parts surround a water storage chamber 35, and the inner core Lid 31 is connected with inner core bottom 33 by connecting column 34, can lift together with inner core bottom 33, leaves the water inlet seam 22 of certain width between inner core cover 31 and outer frame 2 (as image 3 ), when the displacement is not large, then the water inlet slit 33 enters the inner core, and several reinfo...
Embodiment 2
[0045] Figure 6 As shown, it is another embodiment of the present invention. In this embodiment, springs, especially anti-rust springs are used to replace the magnetic parts. In this embodiment, when the spring 62 is used, there is a Positioning column 63, one end of positioning column 63 is fixed on inner core bottom 33, the other end passes through base 4, spring 62 surrounds the outer periphery of positioning column 63, when spring 62 is compressed, positioning column 63 can protrude from the bottom surface of base 4; When the amount of water in the water storage cavity decreases, the spring 62 undergoes reset deformation, and the spring elongates to return the inner core to its original position.
Embodiment 3
[0047] There are also different ways to design the guide column, such as Figure 7-8 As shown, the guide column 41 is located outside the inner core wall 32, and a longitudinal guide groove 11 for accommodating the guide column is provided at a corresponding position inside the outer cavity 1, and the guide column 41 can slide along the guide groove 11. Further, the The number of the above-mentioned guide columns can also be more than one, preferably an even number, and evenly and symmetrically distributed around the drainpipe. The guide columns are designed on the outer periphery of the inner core, which can obtain more stable effect.
