Or replace it. The muffler 23 is disposed between the air inlet n and the inlet 24 of the compressor 24 to reduce the noise generated when the gas flows in the pipe. The sealed box 26 is used to seal components such as the compressor 24, the solenoid valve 25, and the muffler, and the noise during operation is reduced. 2〇 In addition, please refer to FIG. 4 together as a perspective view of the embodiment. The fan 33, the timer 34, the screen indicator lamp 35, and the power switch 36 are electrically connected to the compression j24. When the compressor 24 is operated, the fan 33 is also activated, and the hot air generated during the operation of the inside of the casing 10 can be discharged by the air outlet 13 on the phase body 10. As for the timer 34, there are three time periods of 1〇, 20, 30 minutes, etc. The M290880 can display the time limit, and the user can control the time required for the preset operation. The filter indicator light 35 is configured to set the filter indicator light 35 to flash when the compressor 24 is operated for a predetermined number of hours, prompting the user to replace the air filter 2 1 and the activated carbon filter 22, in this example, When the compressor 5 24 is operated for 1000 hours, the screen indicator lamp 35 flashes. Further, the power switch 36 is disposed around the timer 34 for starting or shutting down the operation of the compressor 24. Referring to Figures 1 and 2, the air inlet port of the casing of the present invention communicates with the inlet 241 of the compressor 24, and the outlet 242 of the compressor 24 communicates with the inlet valve 251 of the five-way 10 valve 25. The five-way valve 25 has an inlet valve 251, a first outlet valve 252, a second outlet valve 253, a first opening valve 254, and a second opening valve 255. Further, the electromagnetic controller 250 is assembled on the five-way valve 25, and the electromagnetic controller 250 selectively controls the inlet valve 251 of the five-way valve 25 to communicate with the first opening valve 254, and at the same time, the second opening valve 255 The inlet valve 251, which is in communication with the second outlet valve 253, or alternatively controls the five-way valve 25, communicates with the second opening valve 255, and at the same time the first opening valve 254 communicates with the first outlet valve 252. In addition, the first molecular sieve cylinder 27 has an inlet end 271 and an outlet end 272. The inlet end 271 is 20-passed with the first opening valve 254 of the five-way valve 25, and the outlet end 272 is connected to a first oxygen delivery tube 41. . The second molecular sieve cylinder 28 also has an inlet end 28 and an outlet end 282. The inlet end 281 is in communication with the second opening valve 255 of the five-way valve 25, and the outlet end 282 is connected to a second oxygen delivery tube 42. The second oxygen transfer pipe 42 is in communication with the first oxygen transfer pipe 41 and is provided with a throttle valve 30. The throttle valve 30 is also in communication with the inlet 291 of the oxygen storage cylinder 29, and stores 10 M290880 oxygen and the inlet 291 of the 29, and is provided with a check valve 44 to ensure that the oxygen storage machine is in operation. When the oxygen and the oxygen generator are not operating, the outside air does not flow back to the first molecular sieve cylinder 27 and the second molecular cylinder 4 through the oxygen storage cylinder 29. Furthermore, the outlet 292 of the oxygen storage cartridge 29 is combined with a flow control chamber 5 46' to communicate with the oxygen outlet 12 of the tank 10 for the user to adjust the required oxygen flow rate. As shown in FIG. 1, when the five-way valve 25 of the present invention is controlled to operate in the first mode via the electromagnetic controller 25, the air (Air) outside the casing 10 is forcibly sucked through the inlet 241 of the compressor 24, via the compressor. The outlet 242 of the 24 is in communication with the inlet valve 251 of the five-way valve 10, and leads to the first molecular sieve cylinder 27 via the first opening valve 254 of the five-way valve 25, and the air flows into the first molecular sieve cylinder 27 during the crucible. The molecular sieve system is in the adsorption stage, and the nitrogen gas (N2) can be adsorbed. Because of the =, the outlet end 272 of the first molecular sieve cylinder 27 outputs oxygen (〇2), and is stored by the first oxygen delivery tube 41 to the oxygen storage cylinder 29. . And a small portion of the oxygen produced by the first molecular sieve cylinder 27 flows through the throttle valve 30 to the second molecular sieve cylinder 28, and dilutes the nitrogen gas therein, that is, the molecular sieve system of the second molecular sieve cylinder 28 is in the desorption stage. It is reduced to a stage where it can adsorb nitrogen and can produce oxygen. As shown in FIG. 2, when the five-way valve 25 of the present invention is controlled to operate in the second mode via the electromagnetic controller 250 20, the air outside the casing 1 passes through the first opening valve 254 of the five-way valve 25 to the second. The molecular sieve cylinder 28, at this time, the molecular sieve of the second molecular sieve cylinder 28 is in the adsorption stage. Therefore, the second molecular sieve cylinder 28 takes out oxygen (〇2) and is stored by the second oxygen delivery tube 42 to the oxygen storage cylinder 29. And a small portion of the oxygen produced by the first molecular sieve cylinder 28 is also directed to the first molecular sieve cylinder 27 via the throttle flow 11 M290880, at which time the molecular sieve of the first molecular sieve cylinder 27 is in the desorption phase. Thereby, the electromagnetic controller 250 of the present invention can control the five-way valve 25 to adjust the first mode and the second mode of the valve port interactive switching, that is, control the air to enter the first molecular sieve cylinder 27 and the second at 5 different times. The molecular sieve cylinder 28 causes the molecular sieve in one molecular sieve cylinder to be in the adsorption stage, while the molecular sieve in the other molecular sieve cylinder is in the desorption stage, and the flow rate and pressure are controlled by the throttle valve 30. A molecular sieve cylinder 27 and a second molecular sieve cylinder 28 can alternately produce oxygen at a concentration of 30 to 35% to increase the efficiency of the production of oxygen.
