The exhaust mechanism comprises a sealing sheet 27 in sealing sliding connection with the top in the rectangular groove 25 and a permanent magnet 23 fixedly connected with the lower end part of the inner wall of the gas collecting hood 18, the sealing sheet 27 is elastically connected with the inner wall of the rectangular groove 25 through a spring 28, damping exists between the sealing sheet 27 and the top in the rectangular groove 25, and the sealing sheet 27 has magnetism.

It should be noted that, when the sealing sheet 27 and the permanent magnet 23 are in the flush position, the sealing sheet 27 and the permanent magnet 23 are in the same polarity and opposite to each other, and a repulsive force is generated between the sealing sheet 27 and the permanent magnet 23, and the repulsive force overcomes the resistance force of the spring 28 and the damping of the sealing sheet 27 and the top of the rectangular groove 25, so as to push the sealing sheet 27 away from the exhaust port 26; and the elastic force of the spring 28 is slightly larger than the damping of the sealing sheet 27 and the top of the rectangular groove 25, when the sealing sheet 27 loses the repulsion force of the permanent magnet 23 to push, the sealing sheet 27 slowly slides under the elastic force of the spring 28, and the exhaust port 26 is sealed again after a period of time.

The upper end fixedly connected with gas-supply pipe 7 of square pipe 5, the one end intercommunication that gas inlet 6 was kept away from with square pipe 5 through air duct 12 to gas-supply pipe 7, and the upper end of gas-supply pipe 7 all is equipped with gas transmission mouth 16, installs the check valve 17 that only allows oxygen to flow from up down in the gas transmission mouth 16, installs the elevating system who is used for not hard up silt in the gas-supply pipe 7.

Elevating system includes the equipartition in 7 upper ends of gas-supply pipe and with the crisscross lifter 13 that sets up of gas transmission port 16, lifter 13 run through the upper end of gas-supply pipe 7 and rather than sealed sliding connection, the head 14 is smash to the upper end fixedly connected with hemisphere of lifter 13, the first permanent magnet 15 of lower extreme fixedly connected with of lifter 13, the relative inner wall of square pipe 5 rotates between and is connected with pivot 8, installs the power unit that is used for driving lifter 13 to go up and down on the pivot 8.

The power mechanism comprises an impeller 9 and a plurality of round wheels 10 which are coaxially and fixedly connected to the rotating shaft 8, the positions of the round wheels 10 correspond to the lifting rods 13 one by one, a second permanent magnet 11 is fixedly connected to the side wall of the cambered surface of each round wheel 10, and the relative positions of each second permanent magnet 11 and the round wheel 10 where the second permanent magnet 11 is located are different.

When the second permanent magnet 11 rotates to a position close to the top in the square pipe 5 along with the round wheel 10, the upper end magnetic pole of the second permanent magnet 11 is the same as the lower end magnetic pole of the first permanent magnet 15, and repulsion force is generated between the upper end magnetic pole and the lower end magnetic pole, so that the lifting rod 13 can be pushed to ascend, when the second permanent magnet 11 rotates to a position close to the bottom in the square pipe 5 along with the round wheel 10, the distance between the second permanent magnet 11 and the first permanent magnet 15 is far, the magnetic force action between the second permanent magnet 11 and the first permanent magnet 15 can be ignored, and the lifting rod 13 descends under the action of.

In the invention, when the oxygen generator 2 works, oxygen enters the telescopic air bag 25, the telescopic air bag 25 is inflated and expanded, when the plastic part 24 reaches the position flush with the permanent magnet 23, the repulsion force between the permanent magnet 23 and the sealing sheet 27 pushes the sealing sheet 27 away from the exhaust port 26, and at the moment, the air in the telescopic air bag 25 is ejected at a high speed;

and after the air in the telescopic air bag 25 is sprayed out partially, the telescopic air bag 25 contracts, the positions of the sealing sheet 27 and the permanent magnet 23 are staggered, the horizontal component force of the repulsion force of the permanent magnet 23 to the sealing sheet 27 becomes very small and can be ignored, at the moment, the sealing sheet 27 can slide slowly only under the action of the elastic force and the damping of the spring 28, and the exhaust port 26 is sealed again after a period of time, in the period of time, the air in the telescopic air bag 25 can be sprayed out completely at high speed to drive the axial flow fan 21 to rotate, the saturday fan 21 drives the disc 3 to rotate, so that the L-shaped air chamber 4 rotates to be communicated with a square pipe 5, and oxygen enters the square pipe 5.

When the telescopic air bag 25 is closed again, the axial flow fan 21 and the disc 3 stop rotating, the telescopic air bag 25 continues to inflate and expand, when the telescopic air bag is opened next time, the axial flow fan 21 drives the disc 3 to rotate again, the L-shaped air cavity 4 is communicated with the adjacent square pipe 5, and oxygen enters the adjacent square pipe 5.

Oxygen in the square pipe 5 of input passes through in the air duct 12 gets into the gas-supply pipe 7, and export from gas transmission port 16, make near this gas-supply pipe 7 oxygen content higher, the good oxygen fungus of other positions tends to this gas-supply pipe 7 and removes, and when this position gas-supply pipe 7 does not supply oxygen, when having oxygen in its adjacent position gas-supply pipe 7, good oxygen fungus again tends to the gas-supply pipe 7 of adjacent position and removes, can promote the flow and the blending of good oxygen fungus of each position in the silt layer, with the whole quality that improves the fungus crowd, promote biochemical treatment effect.

When oxygen flows through from square pipe 5, the air current can drive impeller 9 and rotate, impeller 9 drives pivot 8 and rotates, a plurality of round wheels 10 of pivot 8 drive synchronous rotation, thereby make second permanent magnetism piece 11 and the continuous keeping away from of first permanent magnetism piece 15 be close to, make lifter 13 rise the decline constantly under magnetic force and gravity cooperation, thereby make hemisphere smash head 14 and become flexible in succession to near the silt of gas-supply pipe 7, make the oxygen in the gas-supply pipe 7 release more easily in the silt, help improving near the silt content of gas-supply pipe 7.

And because the relative position of second permanent-magnet 11 rather than the round wheel 10 at place is all different, make round wheel 10 when rotating, every second permanent-magnet 11 is not synchronous with keeping away from with being close to of first permanent-magnet 15, thereby make the rising and the decline of many lifter 13 not synchronous, make the not hard up degree of silt of different positions different, thereby make the oxygen content of same gas-supply pipe 7 different positions also have the difference, can make originally also be in the state of constantly moving in the fungus crowd that just is located near this gas-supply pipe 7, further guarantee the activity of fungus crowd, promote biochemical treatment effect.

The above description is only for the preferred embodiment of the present invention, but the scope of the present invention is not limited thereto, and any person skilled in the art should be considered to be within the technical scope of the present invention, and the technical solutions and the inventive concepts thereof according to the present invention should be equivalent or changed within the scope of the present invention.
