Second embodiment
For some users, as the rehabilitation progresses, the heart and lung functions of the body are gradually restored, and the requirement for high oxygen concentration is gradually reduced. If the high-concentration oxygen with constant concentration is continuously supplied in the rehabilitation process of the user, the exercise and the rehabilitation of the heart and lung functions of the patient are not facilitated; second, when the user does not need high concentration oxygen, the continuous supply of high concentration oxygen also affects the useful life of the molecular sieve 103. Therefore, the oxygen concentration to be supplied needs to be adaptively adjusted according to the needs of the user for the oxygen concentration.
When the heart and lung functions of the user are gradually recovered, the device can be used for supplying oxygen with different concentrations according to the requirement of the user on the oxygen concentration. Specifically, by controlling the rotation of the adjusting motor, the adjusting motor drives the sealing turning plate 107 to rotate through the connecting shaft, so that the sealing between the upper molecular sieve 103 and the lower molecular sieve 103 is opened, and then a part of the supplied air directly flows onto the upper molecular sieve 103 from the lower molecular sieve 103, and the oxygen-enriched effect of the molecular sieve 103 is avoided, so that the oxygen content is relatively low; the other part of air is blocked by the sealing turning plate 107, passes through the air holes on the lower supporting framework 104, then passes through the molecular sieve 103 on the lower part for adsorption treatment, passes through the ventilation groove 106, reaches the molecular sieve 103 on the upper part for re-adsorption treatment, then reaches the inside of the supporting framework through the air holes on the upper supporting framework 104, and is discharged; the part of air is air after oxygen enrichment; the air which is not subjected to oxygen enrichment and the air which is subjected to oxygen enrichment are mixed and then supplied to a user through the air guide assembly 2.

Third embodiment
In the above embodiment, due to the threaded connection between the sealing sleeve 115 and the connecting pipe 204 and the arrangement of the connecting portion 114 with a telescopic structure, the connection and the disassembly of the sealing sleeve 115 and the connecting pipe 204 can be realized, so that the molecular sieve assembly 1 can be conveniently removed and installed for overhauling. The maintenance is often used for removing and replacing the molecular sieve 103, and because the air entering the air compressor passes through the preliminary filtration of the dust screen, dust or impurities still pass through the dust screen, enter the molecular sieve 103 along with the air, gather on the molecular sieve 103, and then enter the humidifying bottle 401 along with the air after oxygen enrichment, so that water in the humidifying bottle 401 is easily polluted. The high-frequency molecular sieve 103 is removed for cleaning, so that the normal use of the device can be influenced, and the maintenance amount is increased. Therefore, the workload and convenience of daily cleaning of the molecular sieve 103 are considered.
In normal use of the device, air with a first air pressure value is introduced into the sealing cylinder 102 by controlling the air compressor, the air is blocked by the sealing turning plate 107, the air is supplied firstly through air holes on the supporting framework 104 at the lower part, then is adsorbed by the molecular sieve 103 at the lower part, the air subjected to preliminary adsorption passes through the ventilation groove 106 to reach the molecular sieve 103 at the upper part for re-adsorption, then reaches the inside of the supporting framework through the air holes on the supporting framework 104 at the upper part, and is discharged, and the air after oxygen enrichment is supplied to a user. Through the operating parameter of control air compressor machine, and then the size of the first wind pressure value of control air compressor machine feed, when guaranteeing that the air after the oxygen boosting can satisfy the user demand, make seal turn over board 107 because to flowing air's barrier action, flowing air is lighter than the connecting portion 114 inside supporting spring's the tensile force to the ascending thrust of seal turn over board 107, and the upward thrust of the flow air of first wind pressure value can not drive sealed section of thick bamboo 102 and inside molecular sieve net 103 upward movement to guarantee this device oxygen suppliment during normal use.
When daily cleaning and maintenance are required for the molecular sieve 103 of the sealing cylinder 102, the air compressor is controlled to introduce air with a second air pressure value into the sealing cylinder 102, and the second air pressure value is larger than the first air pressure value. After the air with the second wind pressure value is introduced, due to the blocking effect of the sealing turning plate 107 on the air flow, the flowing air can bear an upward pushing force on the sealing turning plate 107, and the upward pushing force of the flowing air with the second wind pressure value on the sealing turning plate 107 is larger than the stretching force of the supporting spring in the connecting part 114, so that when the flowing air with the second wind pressure value is introduced, the flowing air with the second wind pressure value can push the sealing turning plate 107 to drive the sealing cylinder 102 to move upwards, at the moment, the supporting spring in the connecting part 114 below the sealing cylinder 102 is stretched, and the supporting spring in the connecting part 114 above the sealing turning plate is compressed. When the supply of the flowing air of the second wind pressure value is stopped, the seal cylinder 102 moves downward and returns to the original position by the self gravity and the return action of the support spring. In this way, the repeated supply and stoppage of the supply of the flowing air of the second air pressure value enables the seal cartridge 102 to reciprocate up and down. The inside molecular sieve 103 is driven to reciprocate up and down in the process of reciprocating up and down of the sealing cylinder 102, so that dust or impurities adsorbed on the molecular sieve 103 can fall off, the fallen dust or impurities are driven by flowing air which is subsequently introduced to enter the humidifying bottle 401 along the air guide assembly 3, are filtered by water in the humidifying bottle 401, and further clean the dust or impurities on the molecular sieve 103.
Through the above-mentioned cleaning method to molecular sieve 103, can avoid demolishing the great work load that sealing cylinder 102 and molecular sieve 103 cleared up and produce, automatic control's cleaning method can reduce the clearance work load, improves cleaning efficiency, guarantees the normal use of this device in the maximum extent.
Finally, it should be noted that: the foregoing description is only illustrative of the preferred embodiments of the present invention, and although the present invention has been described in detail with reference to the foregoing embodiments, it will be apparent to those skilled in the art that modifications may be made to the embodiments described, or equivalents may be substituted for elements thereof, and any modifications, equivalents, improvements or changes may be made without departing from the spirit and principles of the present invention.
