Therefore, the through-hole wall 663 pushes the inner body 62 against the elastic force of the elastic body 64 and retreats, so that the retaining ring 621 and The water retaining ring 63 leaves the ring retaining wall 613 (as shown in FIG. 13), and the rear space can be communicated before the ring retaining wall 613 is separated; and the joint end 665 can firmly engage the outlet pipe for extension. (As shown in Fig. 14); therefore, when the liquid in the space after the outer casing 61 is necessary to be discharged after the overall assembly, that is, the water discharge control group 60 is used to complete the assembly, the water discharge control group is firstly 60 is combined with the lower cover group 30, and then the body casing 10 is combined with the lower cover group 30, and then the lower cover group 30 is combined with the air pumping pump 40, and then filled in the large storage cylinders 11, 12 The molecular sieve material is introduced into the filter water cartridge 15 , and the upper cover group 20 is combined with the body casing 10 , and the switching solenoid valves 51 , 52 , 53 , 54 , 55 are assembled to the body casing 10 . And the upper cover group 20, thus completing the oxygen generator 1 as shown in the first and second figures.

When in use, the pumping pump 40 is activated, and the suction force causes the air to pass through the filter 108 and enter the air inlet 13 and then pass through the lower gasket through the through hole 1013 of the bottom surface of the body casing 10. The perforation 322 of the 32 and the perforation 312 of the lower cover 31, and the intake perforation 42 of the pumping pump 40 enter the air pumping tube 40, and are further divided into two channels, respectively, and the air outlets 43 and 44 of the two sides are respectively exhausted and enter. The through holes 313 and 314 of the lower cover 31 are respectively entered into the air flow tubes 111 along the through holes 3131 and 3241 of the through grooves 3131, 3141 and the lower spacer 32, and the through holes 1011 and 1021 of the bottom surface of the body casing 10, respectively. 121 stays and generates a high pressure; then, the automatic control system (additional, not shown) controls the switching solenoid valves 51, 52 to take turns to start, when the switching solenoid valve 51 is activated (at this time) The switching solenoid valve 52 stops operating or restarts after a time difference. The air in the air flow tube 111 enters the air flow tube 112 through the through holes 1031 and 1032, and then passes down through the through hole 1012 of the lower spacer 32 and the The through groove 3132 and the through hole 1001 of the bottom surface of the large storage cylinder 11 enter the bottom of the large storage cylinder 11 and are pushed through the molecular sieve material to be converted into oxygen upwardly; then the oxygen passes through the second upper gasket 24 The through hole 243 and the through hole 2331 of the intermediate cover 23 enter the air pocket 233, and pushes the air closing diaphragm 2333 upward to move along the channel 2332 through the air collecting hole 235 and the through hole 245 to enter the air reservoir 14 to stay, and Pooled for high pressure. When the oxygen reaches the channel 2332, it also reaches the air pocket 234 along the channel 2342, but the pressure instead pushes the air-closing membrane 2343 downwardly against the through hole 2341, so that oxygen cannot enter the large storage cylinder 12 thereby. Therefore, the air-closing membranes 2333, 2343 are a specific implementation of the backstop device; however, in the large storage cylinder 12, there is no need to have no oxygen, so the automatic control system controls the switching solenoid valve 55 to start, so that the large storage A small amount of oxygen in the cylinder 11 reaches the through hole 2131 through the small perforations 2433, 2334, 223 and the through groove 213, and then enters the through hole 2141 and enters the large storage cylinder 12 via the through groove 214 and the small perforations 224, 2344, 2443. In order to facilitate the output of oxygen, it can immediately have oxygen for output.

Since the process of converting air into molecular oxygen through the molecular sieve material generates heat, the automatic control system controls the switching solenoid valve 51 to stop after a period of time, so that the air in the gas flow pipe 111 cannot enter the gas flow pipe 112 through the through holes 1031 and 1032. At the same time, the switching solenoid valve 53 is controlled to be activated, so that the air in the air flow tube 112 enters the air leakage pipe 113 through the through holes 1051 and 1052, and then flows into the air leakage pipe through the top end of the separated wall body. 114, then pass down through the perforation 325 of the lower shim 32 and the perforation 315 of the lower cover 31 to naturally vent out Out to reduce the air pressure in the gas flow tube 112. Before the switching solenoid valve 51 is stopped or has not been completely stopped, the automatic control system will control the other switching solenoid valve 52 to start at the right time, and complete the same oxygen production process by another set of corresponding components, and finally the oxygen is passed. The gas collecting holes 235 and the through holes 245 enter the gas storage tube 14 to stay.

In the present invention, the amount of oxygen in the air reservoir 14 is increased by the process of oxygen production by the large storage cylinders 11, 12. When oxygen is to be used, the gas outlet pipe 212 is first inserted with an extension pipe (as shown in the first and second figures), so as to pull the oxygen to the oxygen, and then open the gas outlet button (alternatively, not shown) Oxygen is vented through the gas outlet pipe 212 and the extension pipe; the high pressure oxygen in the gas storage cylinder 14 enters through the through hole 246, the vent hole 236, the through groove 237, the insertion pipe 238 and the extension pipe 239 The pure water in the water tube 15 is cleaned and then floated upward to be cleaner oxygen, and then the gas outlet pipe 212 and the extension pipe are used for gas supply.

The oxygen generator 1 of the present invention may have a number of equivalent functions, and is also included in the patent scope of the present invention. For example, as shown in the fifteenth diagram, the appearance of the oxygen generator 1 of the present invention may be changed to It is more beautiful, but it does not affect the function of the present invention at all, so it is also within the scope of the patent of the present invention. 2.
