US 2026/0043237 A1 · AIR EXTRACTION INTERFACE WITH SEALING STRUCTURE, POLYCARBONATE VACUUM PLATE, AND SUNLIGHT ROOM

Abstract

An air extraction interface with a sealing structure, a polycarbonate vacuum plate, and a sunlight room are provided. The air extraction interface is an air extraction pipeline or an opening section. One end of the air extraction interface is connected to an air-extracted object. The sealing structure includes a first section located at the air extraction interface and a sealing section. Inner walls of pipelines of the air extraction interface where the first section is located fit each other or there is a gap between the inner walls. The pipelines of the air extraction interface are closed at a position where the sealing section is located. The sealing structure can easily seal the air extraction pipeline made of a hard material, so that air is prevented from entering internal vacuum space of the hard material in a sealing process.

4 more elements

A method for preparing a polycarbonate vacuum plate, comprising the following steps:

a vacuumizing step:
connecting a vacuumizing device to an air extraction interface to vacuumize a multilayered polycarbonate plate main body;
and
a sealing step:
heating, softening, and extruding a first portion of the air extraction interface to allow inner walls of an extruded portion of the air extraction interface continuously to fit each other to form a first section, so as to temporarily close a pipeline of the air extraction interface;
hot-melting and extruding a second portion of the air extraction interface to form a sealing section, to permanently close the pipeline of the air extraction interface;
and removing extrusion to the first section, wherein the inner walls of the first section are maintained to fit each other or there is a gap between the inner walls of the first section.
