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.

Please refer to fig. 1-3, the utility model provides a multilayer composite construction polyurethane environmental protection sponge substrate, including sponge middle level 5, mounting groove 3 that extends to the lower extreme is seted up to sponge middle level 5 terminal surface, mounting groove 3 makes sponge middle level 5 be the framework, the internal fixation of mounting groove 3 is equipped with activated carbon sponge 4, activated carbon sponge 4 is inside to be fixed and is equipped with evenly distributed's activated carbon particle, activated carbon sponge 4 is equipped with two-layerly, and be range upon range of setting, the fixed one deck felt layer 7 that is equipped with between two-layer activated carbon sponge 4, both ends face is all fixed and is equipped with a layer of polyurethane sponge layer 2 about sponge middle level 5, polyurethane sponge layer 2 deviates from the fixed one deck memory sponge top layer 1 that is equipped with of end of sponge middle level 5, set up evenly distributed's through-hole.

Wherein, the through-hole 202 middle part is equipped with a circle of closed ring 201, and closed ring 201 center department is equipped with a hole, and under the circumstances of not atress, the hole normal close, when the atress was dragged, the hole can be opened, is equipped with the fold line on the downthehole wall, makes things convenient for the atress to open, and inner end hole 203 has been seted up to the end that through-hole 202 and active carbon sponge 4 meet, and inner end hole 203 diameter is greater than through-hole 202, increases the contact surface of through-hole 202 and active carbon sponge 4, improves the filter effect.
