The gap between the foam eliminating plate 5213 and the inner wall is a ventilation gap, so that the foam eliminating structure 521 can also prevent the foam from overflowing on the premise of realizing the ventilation function of the ventilation pipe 52. The anti-overflow portion includes two piece at least defoaming boards 5213, defoaming board 5213 parallel arrangement or alternately set up each other, between the defoaming board 5213 there is ventilative space between defoaming board 5213 and the defoaming end 5212 inner wall, and when foam overflowed to the defoaming end 5212 from link 5211, earlier by the necking down portion extrusion of link 5211 partly breaks, the remainder is met after being extruded and is extruded again and break by the defoaming board 5213, does not have the foam to spill over from the defoaming end 5212. The integrally formed defoaming plate 5213 saves processing and mounting steps, saves cost and is convenient to use.

The foregoing description is only illustrative of the preferred embodiment of the present invention, and is not to be construed as limiting the invention, but is to be construed as limiting the invention to any simple modification, equivalent variation and variation of the above embodiments according to the technical matter of the present invention without departing from the scope of the invention.
