The air compressor 102 pressurizes the air and passes the pressurized air into the gas screening structure. The gas screening structure filters out the oxygen in the air and then passes it into the gas output structure. The gas output structure outputs high-purity oxygen to achieve oxygen production. When replacing the molecular sieve in the gas screening structure, the protective cover 402 is quickly disassembled using the snap-on structure, the air pipe connecting the gas screening structure is unplugged, and the gas screening structure is quickly disassembled using the limiting structure, so as to facilitate the replacement of the molecular sieve in the gas screening structure.

[0027] In one embodiment, Figure 3 As shown, the gas screening structure includes a screening tank 201, the upper end of the screening tank 201 is threadedly connected to a tank cover 202, the gas outlet end of the gas screening structure is located on the tank cover 202, and the gas inlet end of the gas screening structure is arranged at the lower end of the screening tank 201. The screening tank 201 is filled with gas screening particles. The compressed air flows through the screening tank 201 from bottom to top and is filtered by the gas screening particles in the screening tank 201.

The surface is provided with a limiting hole 308 that matches the limiting column 307. During installation, first align the limiting hole 308 with the limiting column 307, place the screening tank 201 on the base 101, and then rotate the screening tank 201 to make the block 301 on the screening tank 201 slide into the L-shaped limiting block 302. During this process, the block 301 squeezes the top block 304 to make the top block 304 shrink. After the block 301 is in place, under the action of the spring 305, the top block 304 resets and squeezes the block 301, limiting the block 301 in the L-shaped limiting block 302, thereby fixing the screening tank 201.

The clamping strip 404 is arranged on the protective cover 402, and the clamping slot 405 is arranged on the base 101. The position of the clamping slot 405 corresponds to the clamping strip 404. The clamping strip 404 is provided with a pulling block 406 for pulling the clamping strip 404.

[0032] The above embodiment discloses a medical oxygen production device with an easily replaceable molecular sieve, wherein air is filtered through the air filter 103 and then enters the air compressor 102. The air compressor 102 pressurizes the air and passes the pressurized air into the screening tank 201. The compressed air flows from the bottom to the top through the screening tank 201 and is filtered by the gas screening particles in the screening tank 201. Finally, high-purity oxygen flows out of the screening tank 201 and enters the gas storage tank 104 for temporary storage. The oxygen output is controlled by the flow control valve 105 according to the actual demand for oxygen. When the molecular sieve needs to be replaced, the clamping strip 404 is pulled by the lever block 406 to make the clamping strip 404 elastically deformed, and the clamping strip 404 is separated from the clamping slot 405. The protective cover 402 is removed, and then the air pipe connected to the screening tank 201 and the tank cover 202 is unplugged. The screening tank 201 is rotated and removed from the base 101. The tank cover 202 is unscrewed to replace the gas screening particles, which is more convenient to operate.
