Abstract:
1. A multi-channel circulation oxygen generator, comprising: a body shell, a top cover set and a base set; wherein said body shell is an all-in-one shape having an open top end and bottom end, and having an interior shaped into a plurality of connecting septum walls that form a plurality of big tanks which are filled with molecular sieve substances, the big tanks being surrounded by a set of gas intake passage, a gas storage tank and a set of gas outtake passage; the big tanks being hollow inside; the set of gas intake passage being made up of several hollow gas intake channels, where pairs of adjoined gas intake channels are provided with a circulating cavity alternately at the top or the bottom of the septum wall between them, which forms a top and a bottom circulations; the gas storage tank being an independent hollow duct; the set of gas outtake passage being made up of several hollow gas outtake channels, where pairs of adjoined gas outtake channels are provided with a circulating cavity alternately at the top or the bottom of the septum wall between them, which forms a top and a bottom circulations; said top cover set being made up of a top cover and a top spacer, assembled fixedly on the top of said body shell; the top cover being provided with a pressure regulator and an outtake tube set up on top of the top cover, and with a gas inlet and a gas outlet at sides of the top cover; the top cover being provided with a plurality of big circular dents corresponding to the aforesaid big tanks, and the big circular dents each covering a respective small circular dent, where a gas collecting tube joins the small circular dents and is provided with a gas collecting hole in the middle of a bottom part of the gas collecting tube which extends downward to the gas storage tank; a chamber being set up to fit in the gas storage tank, and the pressure regulator and the outtake tube being set up inside the chamber, where a bottom of the chamber has a through hole, to let the air of the gas storage tank in, and further into the pressure regulator and the outtake tube; the gas inlet and the gas outlet both extending to the internal of the top cover; in each of the small circular dents, an elastic article being placed in the small circular dent, a gas shut membrane covering the elastic article to hold the elastic article, further with a gas shut cover, which has a through hole at its center, a filter net and a filter slice covering the gas shut cover, the filter slice, the filter net, the edge of the gas shut cover being penetrated by a fastener fastened with a threaded hole at the outer edge of the small circular dent, to seal the gas shut membrane in between the gas shut cover and the small circular dent; the top spacer being closely attached to the bottom side of the top cover, and big circular openings being placed at the place corresponding to the big circular dents; a through hole being set up at the place corresponding to the gas collecting hole; a piercing hole being set up at the place corresponding to the chamber; a through hole being set up at the place corresponding to each of the gas inlet and the gas outlet; said base set being made up of a base and a bottom spacer, and assembled fixedly at the bottom of said body shell; the base being provided with a plurality of big circular dents at a top side of the base corresponding to the aforesaid big tanks; a gas-in hole being set up in each of the big circular dents; a gas-in hole being placed corresponding to the last gas intake channel of the gas intake passage; a gas-out hole being placed corresponding to the first gas outtake channel of the gas outtake passage; the base being provided at a bottom of the base with a plurality of switching solenoid valves corresponding to the aforesaid big tanks, which control the circulation or cutoff between the gas-in hole of the big circular dent and the gas-in hole of the last gas intake channel of the gas intake passage, and controlling the circulation or cutoff between the gas-in hole of the big circular dent and the gas-out hole of the first gas outtake channel of the gas outtake passage; the bottom spacer being positioned closely between the base and the bottom side of said body shell; and a plurality of big circular openings being set up at the bottom spacer corresponding to the big circular dents and the big tanks; a through hole being set up corresponding to each of the gas-in hole of the last gas intake channel of the gas intake passage and the gas-out hole of the first gas outtake channel of the gas outtake passage.
