Detailed Description

The present invention will now be described in further detail with reference to the accompanying drawings. These drawings are simplified schematic drawings and illustrate the basic structure of the present invention only in a schematic manner, and thus show only the components related to the present invention.

An oxygen generator shown in fig. 1 and 2 comprises a conventional a molecular sieve tank 1, a conventional B molecular sieve tank 2 and a conventional gas storage tank 3, wherein one path of outlet gas of the a molecular sieve tank and one path of outlet gas of the B molecular sieve tank are respectively connected with a gas inlet of the gas storage tank 3 through a pipeline, an end cover 4 is detachably mounted on the gas storage tank 3, specifically, 4 hole seats which are forcibly detached and mounted are respectively arranged in the circumferential direction of the end cover 4 and the circumferential direction of the outer wall of the gas storage tank 3, the corresponding hole seats on the end cover 4 and the gas storage tank 3 are mounted and detached by screwing or unscrewing bolts, and the hole seats are designed conventionally so that no hole seat or bolt mark is arranged in the drawing; in order to improve the circumferential direction of the air tightness end cover 4, a sealing ring 5 is arranged, and after the end cover 4 and the air storage tank 3 are installed, the tank body of the air storage tank 3 is pressed on the sealing ring 5.

The end cover 4 is mainly made of plastic, polyester or resin, and in order to reduce the production cost and facilitate subsequent processing, the utility model mainly adopts plastic materials; firstly, a first air inlet 4-1 and a second air inlet 4-2 which are used for being connected with an air outlet of a molecular sieve tank A1 and an air outlet of a molecular sieve tank B2 are arranged on an end cover 4, so that the two molecular sieve tanks can be communicated with an air storage tank 3, then the first inlet port 4-1 and the second inlet port 4-2 are ground to remove burrs thereon to make the outlet flat, and at the ends of the first inlet port 4-1 and the second inlet port 4-2, namely, a first sealing element 4-3 and a second sealing element 4-4 are respectively arranged on two inlets of the air storage tank 3, the diameters of the first sealing element 4-3 and the second sealing element 4-4 are larger than the pore diameters of the first air inlet 4-1 and the second air inlet 4-2, and the first sealing element 4-3 and the second sealing element 4-4 are commercially available sealing rubber mats; with reference to fig. 2, the lower end faces of the first sealing element 4-3 and the second sealing element 4-4 are pressed on the ends of the first air inlet 4-1 and the second air inlet 4-2, the upper end faces are mounted at the left end and the right end of the reed 4-5 by gluing, screw fixing or thread fastening, the reed is a commercially available metal reed or silica gel reed, and the silica gel reed is used for prolonging the service life and reducing the cost.

When the utility model is actually used, when the first sealing element 4-3 or the second sealing element 4-4 is pushed by the air outlet pressure of the A molecular sieve tank 1 or the B molecular sieve tank 2 to lift upwards, the gas flows into the gas storage tank 3, when the air outlet of the A molecular sieve tank 1 or the B molecular sieve tank 2 is reduced or stopped, the first sealing element 4-3 or the second sealing element 4-4 slowly descends under the action of the reed 4-5, and finally is pressed at the first air inlet 4-1 or the second air inlet 4-2 to prevent the gas from flowing back, meanwhile, the utility model discloses in order to further reduce the noise of the oxygenerator in use, the aperture on the mutual connecting pipeline of the A molecular sieve tank 1 and the B molecular sieve tank 2 is enlarged, and it is also possible to change into a pipeline direct connection.
