Detailed Description

The technical solutions in the embodiments of the present invention will be described clearly and completely with reference to the accompanying drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only some embodiments of the present invention, not all embodiments. Based on the embodiments in the present invention, all other embodiments obtained by a person skilled in the art without creative work belong to the protection scope of the present invention.

Referring to fig. 1-3, the present invention provides a technical solution: the utility model provides a waterproof silica gel is sealed to fill up, includes rubber ring 4, and the lower terminal surface fixedly connected with isolation layer 1 of rubber ring 4, the lower terminal surface fixedly connected with expansion layer 3 of isolation layer 1, the lower terminal surface fixedly connected with of expansion layer 3 dredge layer 5, dredge the lower terminal surface fixedly connected with shunting layer 9 of layer 5.

In this embodiment: solve the seepage problem of liquid from the root through rubber ring 4, prevent the liquid seepage problem after the sealed pad absorbs the moisture, isolation layer 1 is the plastic film goods, can provide good lock water effect, firmly pin sealed absorptive liquid, further prevent the liquid seepage, inflation layer 3 is elastic silica gel, can effectual absorption liquid after-expansion, inflation layer 3 inflation makes whole sealed pad volume grow behind the absorption liquid, strengthen the waterproof performance of sealed pad, and the setting of dredging layer 5 can accelerate the efficiency that liquid got into inflation layer 3, improve the practicality of sealed pad, diffluence layer 9 is hydrophobic chromatography, can effectively separate liquid molecule into the water droplet form, make things convenient for liquid to get into inside dredging layer 5.

Specifically, the dredging layer 5 comprises a lock catch 7, liquid guide pipes 6 are fixedly connected to the left side and the right side of the lock catch 7, and two through holes 8 which are distributed up and down are formed in the outer wall of the lock catch 7.

In this embodiment: the position of fixed catheter 6 that hasp 7 can be fine prevents that the slope of catheter 6 from perhaps dropping, influences the efficiency that liquid got into expansion layer 3, and the through-hole 8 that hasp 7 outer wall was seted up alleviates hasp 7 weight, and then alleviates the weight of whole sealed pad.

Specifically, a plurality of water-absorbing fibers 2 are uniformly distributed in the expansion layer 3, and the water-absorbing fibers 2 are mutually wound polymer water-absorbing filaments.
