The silica gel sealing piece 12 comprises a main body, the main body has a through passage, and the upper end and the lower end of the main body are respectively provided with an upper sealing part 121 and a lower sealing part 122. A pressure relief groove 123 for providing a deformation space for the upper part of the main body during installation is arranged around the upper sealing part 121 of the main body, and the depth of the bottom surface of the pressure relief groove 123 is lower than the lower plane of the center hole 124 end of the upper sealing part 121. The pressure relief groove 123 in the embodiment is a ring groove with an opening in the upper part of the main body. The pressure relief groove alleviates the pressure when the sealing piece is assembled with the cavity of the upper water pipe 11, ensures that the sealing opening of the silica gel sealing piece 12 will not be deformed, and thus a more reliable sealing effect is achieved.

[0027] In order to further ensure the sealing effect of the silica gel sealing piece 12 and the steel ball 13, the upper sealing part 121 is upwardly protruding in the embodiment, and is a tapered surface 1211 with a diameter gradually increasing upwards, and the lower sealing part 122 is one or more annular ribs arranged on the inner wall of the passage. The upward protruding arrangement of the upper sealing part 121 ensures that the silica gel sealing ring will not affect the upper sealing part 121 even if it is deformed during installation, and further ensures that the upper sealing part 121 will not be deformed when in contact with the steel ball 13 for sealing.

[0028] In order to enable the steel ball 13 to not deviate from the upper sealing part 121 of the silica gel sealing part 12 when moving up and down, the inner wall of the upper water pipe 11 is provided with a plurality of vertical limiting ribs 111 in the embodiment, a water flow channel is reserved between the adjacent two limiting ribs 111, the plurality of limiting ribs 111 enclose a space with an inner diameter slightly larger than the steel ball 13, so that the steel ball 13 can move up and down in the space and not produce excessive horizontal shaking, and the space is located directly above the silica gel sealing part 12, a first spring 14 is arranged in the space enclosed by the limiting ribs 111, one end of the first spring 14 abuts against the steel ball 13, and the other end abuts against the inner wall of the upper water pipe 11, and in the embodiment, the inner wall of the upper water pipe 11 is provided with a pushing part 112 for pushing the first spring 14, and the water flows out through the gap between the pushing part 112 and the limiting ribs 111, and in the embodiment, the upper sealing part 121 of the silica gel sealing part 12 extends into the space. Since the steel ball 13 can only move up and down, it will accurately fall on the upper sealing part 121 of the silica gel sealing part 12 each time, thereby ensuring that the steel ball 13 does not deviate to cause water leakage.

[0029] In the embodiment, the lower water pipe 21 includes an L-shaped pipe 211 and a fixed clamping piece 212 clamped with each other, the upper end of the L-shaped pipe 211 is inserted into the fixed clamping piece 212, a plurality of first clamping protrusions 2111 are arranged outside the insertion end of the L-shaped pipe 211, the fixed clamping piece 212 is correspondingly provided with clamping holes 2121 for clamping the first clamping protrusions 2111, the lower water pipe 21 penetrates through the lower seat body 2, the lower seat body is provided with a through hole for the lower water pipe to pass through, and a guide protrusion 2112 is arranged outside the insertion end of the L-shaped pipe 211, and the inner wall of the through hole of the lower seat body 2 is correspondingly provided with a positioning groove 26 for inserting the guide protrusion 2112. The fixed clamping piece 212 and the lower seat body 2 are provided with a second spring 22 for elastically pushing the entire lower water pipe 21 upward. The L-shaped pipe of the lower seat body 2 is provided with the positioning guide protrusion 2112, and the lower seat body is provided with the positioning groove 26, so that the assembly cannot be assembled in reverse, because the L-shaped pipe 211 has certain requirements in the installation in the embodiment, and therefore the guide protrusion 2112 and the positioning groove 26 enable the L-shaped pipe 211 to be installed in only one direction, thereby achieving the purpose of not being assembled in reverse.

[0030] Embodiment two

[0031] Please refer to Figure 6 and Figure 7As another embodiment, the difference between this embodiment and embodiment one is only that the drain pipe 21 of this embodiment is a straight pipe, wherein the outer periphery of the straight pipe is provided with a protruding reverse buckle 27, the lower seat body 2 is provided with a through hole for inserting the drain pipe 21, the side wall of one end of the through hole is provided with an elastic supporting arm 23 capable of generating radial elasticity, the reverse buckle passes the elastic supporting arm 23 after the straight pipe is inserted to form a buckling connection, and a third spring 24 is arranged between the straight pipe and the lower seat body 2 to elastically push the entire drain pipe 21 upward. The elastic supporting arm 23 is formed by two cutting grooves 25 opened on the side wall of the through hole of the lower seat body 2. The outer side of the straight pipe is provided with a guide protruding strip 2112, and the side wall of the corresponding through hole of the lower seat body 2 is provided with a positioning groove 26 for inserting the guide protruding strip 2112.
