Two first fixing holes 16 are provided on the surface of the first fixing block 15. The diameters of the first fixing hole 16 and the second fixing hole 18 are adapted to each other. The limiting rod 23 is adapted to the diameters of the first fixing hole 16 and the second fixing hole 18. The motor 24 is started, and the motor 24 drives the screw rod 20 to rotate. The rotation of the screw rod 20 drives the movable plate 22 on its surface to move up and down on its surface. The movable plate 22 moves up and down to drive the limiting rod 23 to move up and down. While the movable plate 22 moves, both sides can move up and down on the surface of the fixing rod 19 to play a stabilizing role. When moving, the limiting rod 23 can be inserted into and away from the first fixing hole 16 and the second fixing hole 18, respectively, so that the coarse filter plate 13 and the fine filter plate 14 can be fixed and disassembled conveniently.

[0024] like Figure 1 , Figure 2 , Figure 3 and Figure 6As shown, one end of the automatic water pump 5 is fixedly connected to a water pumping inlet pipe 8, and the outer surface of the water pumping inlet pipe 8 is provided with an upper protective pipe 6 fixedly connected to one end of the automatic water pump 5, and one end of the upper protective pipe 6 is fixedly connected to a flange 7, and one end of the water pumping inlet pipe 8 is fixedly penetrated and extended to the outside of the flange 7, and the bottom of the automatic water pump 5 is fixedly connected to a water pumping outlet pipe 12, and the outer surface of the water pumping outlet pipe 12 is provided with a lower protective pipe 9 fixedly connected to the bottom of the automatic water pump 5, and the bottom end of the water pumping outlet pipe 12 is fixedly penetrated and extended to the inside of the water storage box 1, the water pumping inlet pipe 8 is inserted into the condensed water collection place of the oxygen making equipment body, and then the flange 7 is fixed to the oxygen making equipment body, and the automatic water pump 5 is started, and the automatic water pump 5 will drive the water pumping inlet pipe 8 to absorb the condensed water, and then transport it to the water storage box 1 through the water pumping outlet pipe 12.

[0025] like Figure 1 and Figure 3 As shown, a connecting groove 2 is opened on the side of the water storage box 1, a drain pipe 3 is fixedly connected to the side of the water storage box 1, and a valve 4 is movably connected to the surface of the drain pipe 3. The connecting groove 2 facilitates the insertion of the coarse filter plate 13 and the fine filter plate 14. The valve 4 is opened, and then the filtered water in the water storage box 1 is discharged through the drain pipe 3, so that it can be used for other purposes.

[0026] Working principle: When in use, insert the water inlet pipe 8 into the condensed water collection place of the oxygen generator body, and then fix the flange 7 to the oxygen generator body;

[0027] Then, the coarse filter plate 13 and the fine filter plate 14 are inserted into the water storage box 1 through the connecting groove 2. When inserting, the first fixing plate at one end of the coarse filter plate 13 and the fine filter plate 14 is placed on the surface of the second fixing plate inside the water storage box 1, and the first fixing hole 16 and the second fixing hole 18 are aligned. Then, the motor 24 is started, and the motor 24 drives the screw rod 20 to rotate. The rotation of the screw rod 20 drives the movable plate 22 on its surface to move downward on its surface. The downward movement of the movable plate 22 drives the limiting rod 23 to move downward. While the movable plate 22 moves, both sides can move downward on the surface of the fixing rod 19 to play a stabilizing role. When the limiting rod 23 moves downward, it can be inserted into and away from the first fixing hole 16 and the second fixing hole 18, respectively, so as to fix the coarse filter plate 13 and the fine filter plate 14.

[0028] After the fixing is completed, the automatic water pump 5 is started, and the automatic water pump 5 will drive the water inlet pipe 8 to absorb the condensed water, and then transport it to the water storage box 1 through the water outlet pipe 12. In order to reduce the waste of water resources, when the condensed water enters the water storage box 1, it will be double filtered by the coarse filter plate 13 and the fine filter plate 14. When the condensed water is filtered to the point of being reused, the valve 4 is opened to discharge the filtered water through the drain pipe 3, so that it can be used for other purposes;

[0029] As the coarse filter plate 13 and the fine filter plate 14 are used for a longer time, the filtering effect of the coarse filter plate 13 and the fine filter plate 14 will be reduced. In order to avoid affecting the service life of the coarse filter plate 13 and the fine filter plate 14, after regular use for a period of time, the motor 24 is started and the motor 24 rotates in the opposite direction, thereby driving the screw rod 20 to rotate in the opposite direction, thereby driving the movable plate 22 on its surface to move upward on its surface. The upward movement of the movable plate 22 drives the limiting rod 23 to move upward, so that the limiting rod 23 is taken out of the first fixing hole 16 and the second fixing hole 18, until the limiting rod 23 is away from the first fixing hole 16 of the coarse filter plate 13 by a certain distance, and then the handle 11 is held and pulled outward, thereby driving the connecting plate 10 to move outward, and finally driving the coarse filter plate 13 and the fine filter plate 14 to move outward, thereby achieving the replacement and cleaning of the coarse filter plate 13 and the fine filter plate 14.

[0030] Through the above operation, the purpose of regularly replacing and cleaning the coarse filter plate 13 and the fine filter plate 14 can be achieved, so as to avoid affecting the filtering effect of the condensed water over time, thereby failing to achieve the purpose of water recycling.
