[0023] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0024] Example 1

[0025] Please see Figure 1-4 The present invention provides the following technical solution: an oxygen generator with deep desorption molecular sieve, comprising a housing 1, a molecular sieve assembly 6 installed on the inner side of the housing 1, an air inlet pipe 2 installed on one side of the housing 1, an air outlet pipe 4 provided on the side of the housing 1 away from the air inlet pipe 2, and a plurality of self-locking casters 7 provided at the bottom of the housing 1. The housing 1 and the air outlet pipe 4 are connected by a circulating drying device 3, and the housing 1 and the plurality of self-locking casters 7 are connected by a lifting and buffering device 5.

[0026] Specifically, the circulating drying device 3 includes a first electric telescopic rod 31, a fixed box 32, a return air pipe 33, a connecting box 38, and a gas supply pipe 39. The housing 1 and the outlet pipe 4 are connected by the fixed box 32. The first electric telescopic rod 31 is installed on the top of the housing 1. The connecting box 38 is installed on the top of the first electric telescopic rod 31. The return air pipe 33 is installed on one side of the connecting box 38 and above the fixed box 32. The gas supply pipe 39 is installed on the side of the connecting box 38 away from the return air pipe 33.

[0027] By adopting the above technical solution, the staff can send the oxygen discharged from the molecular sieve assembly 6 back into the molecular sieve assembly 6 for reprocessing when needed through the cooperation of the first electric telescopic rod 31 and the return air pipe 33, thereby improving the depth of oxygen desorption by the oxygen generator.

[0028] Specifically, the circulating drying device 3 also includes a filter screen 35, and two filters screens 35 are installed inside the connecting box 38.

[0029] By adopting the above technical solution, the oxygen generator can filter the oxygen passing through the connecting box 38 through two filters 35, thereby reducing the possibility of impurities in the final oxygen and better meeting the needs of the staff.

[0030] Specifically, the circulating drying device 3 also includes a silica gel desiccant 36, which is installed inside the connecting box 38 and located between the two filters 35.

[0031] By adopting the above technical solution, the oxygen generator can dry the oxygen passing through the connection box 38 with silica gel desiccant 36 when needed.

[0032] Specifically, the circulating drying device 3 also includes a first buckle 34 and a cover plate 37. The top of the connecting box 38 is provided with a cover plate 37, and the connecting box 38 and the cover plate 37 are connected by two first buckles 34.

[0033] By adopting the above technical solution, the staff can remove the cover plate 37 and open the connection box 38 when needed, which makes it convenient for the staff to replace the silica gel desiccant 36 and to clean the impurities blocked by the filter screen 35.

[0034] In this embodiment, when the oxygen generator needs to be used, it is moved to the work location using the self-locking casters 7. The molecular sieve assembly 6 inside the housing 1 is manipulated, allowing outside air to pass through the inlet pipe 2 and enter the molecular sieve assembly 6 for processing. The first electric telescopic rod 31 in the circulating drying device 3 is activated, causing the connecting box 38 to descend until the return pipe 33 and the supply pipe 39 are respectively connected to the molecular sieve assembly 6 and the inlet pipe 2. The oxygen discharged from the molecular sieve assembly 6 passes through the return pipe 33 and enters the connecting box 38, where it is then filtered and dried by the filter screen 35 and the silica gel desiccant 36. Then, the oxygen passes through the gas delivery pipe 39 and the gas inlet pipe 2 into the molecular sieve assembly 6 for reprocessing, thereby increasing the desorption depth of the oxygen generator. Then, the first electric telescopic rod 31 is activated, so that the return gas pipe 33 and the gas delivery pipe 39 are no longer connected to the molecular sieve assembly 6 and the gas inlet pipe 2. The oxygen discharged from the molecular sieve assembly 6 passes through the fixed box 32 and the gas outlet pipe 4 and is discharged. After the work is completed, when needed, the operator can operate the two first buckles 34 to remove the cover plate 37, open the connection box 38, and then replace the silica gel desiccant 36 and clean the impurities blocked by the filter screen 35.

[0035] Example 2

[0036] The difference between this embodiment and embodiment 1 is that the lifting buffer device 5 includes a support plate 51, a base plate 53, a second electric telescopic rod 55 and a connecting frame 58. The connecting frame 58 is installed on the outer bottom of the housing 1. The base plate 53 is installed on the side of the multiple self-locking casters 7 near the connecting frame 58. The support plate 51 is provided between the connecting frame 58 and the base plate 53. The second electric telescopic rod 55 is installed on both sides of the bottom of the connecting frame 58 above the support plate 51.

[0037] By adopting the above technical solution, staff can adjust the height of the box body 1 and other structures by manipulating the two second electric telescopic rods 55 when needed, thereby better meeting the work needs under different circumstances.

[0038] Specifically, the lifting buffer device 5 also includes a damper 52 and an elastic rubber frame 54. An elastic rubber frame 54 is installed between the base plate 53 and the support plate 51, and multiple dampers 52 are installed between the base plate 53 and the support plate 51 and inside the elastic rubber frame 54.

[0039] By adopting the above technical solution, the oxygen generator can buffer the vibration from the outside world through the cooperation of the damper 52 and the elastic rubber frame 54, thereby reducing the possibility that the oxygen production operation will be adversely affected by the external vibration.

[0040] Specifically, the lifting and buffering device 5 also includes a connecting plate 56 and a second buckle 57. The connecting plate 56 is installed above the second electric telescopic rod 55, and the connecting frame 58 is connected to the two connecting plates 56 through two second buckles 57.

[0041] By adopting the above technical solution, the staff can connect or separate the two second electric telescopic rods 55 and the connecting frame 58 when needed, which facilitates the staff to install and disassemble the two second electric telescopic rods 55 and other structures.

[0042] In this embodiment, when it is necessary to adjust the height of the box body 1 and other structures, the two second electric telescopic rods 55 in the lifting buffer device 5 are activated, thereby driving the connecting frame 58 to move through the two connecting plates 56 and the two second buckles 57, thereby adjusting the height of the box body 1 and other structures. The damper 52 and the elastic rubber frame 54 between the support plate 51 and the bottom plate 53 can buffer external vibrations.

[0043] The structure and principle of the housing 1 and its upper structure, the molecular sieve assembly 6 consisting of a compressor, a filter box, a molecular sieve, a support plate, an oxygen tank, a booster compressor, a buffer sleeve, a buffer spring, and a buffer column, and the self-locking universal wheel 7 have been disclosed in a dual molecular sieve tower oxygen generator capable of uninterrupted gas supply, as disclosed in Chinese Patent Application No. 202020744831.0. Its working principle is as follows: when in use, the compressor is started, and external air is filtered through the filter screen and filter box in the air inlet pipe. The filtered air enters the compressor for compression, and the compressed air enters the molecular sieve for processing through a connecting pipe. The oxygen after molecular sieve processing enters the oxygen tank, and the oxygen in the oxygen tank is discharged through the exhaust pipe. Simultaneously, the oxygen flow rate is monitored in real time by a flow meter on the exhaust pipe. When the flow meter detects a large oxygen flow rate, the booster compressor is started through the controller to increase the oxygen flow rate. When the electrical equipment inside the housing is working, the cooling fan is started to expel the heat generated by the electrical work from the heat dissipation slots on the housing door.

[0044] The structure and principle of the damper 52 in this invention have been disclosed in a smart home washing machine shock absorption device disclosed in Chinese patent application number 201721446985.6. Its working principle is to use damping characteristics to reduce mechanical vibration and consume kinetic energy.

[0045] The working principle and usage process of this invention: When the oxygen generator needs to be used, it is moved to the work location by the self-locking casters 7. The molecular sieve assembly 6 inside the housing 1 is manipulated, and outside air enters the molecular sieve assembly 6 through the air inlet pipe 2 for processing. The first electric telescopic rod 31 in the circulating drying device 3 is activated, thereby driving the connecting box 38 to descend until the return pipe 33 and the air delivery pipe 39 are respectively connected to the molecular sieve assembly 6 and the air inlet pipe 2. The oxygen discharged from the molecular sieve assembly 6 enters the connecting box 38 through the return pipe 33, and is then filtered and dried by the filter screen 35 and the silica gel desiccant 36. Then, the oxygen enters the molecular sieve assembly 6 through the air delivery pipe 39 and the air inlet pipe 2 for reprocessing, thereby improving the desorption depth of oxygen by the oxygen generator. Then, the first... The electric telescopic rod 31 prevents the return pipe 33 and the gas supply pipe 39 from connecting with the molecular sieve assembly 6 and the inlet pipe 2. The oxygen discharged from the molecular sieve assembly 6 passes through the fixed box 32 and the outlet pipe 4 and is discharged. After the work is completed, when needed, the operator can operate the two first buckles 34 to remove the cover plate 37, open the connecting box 38, and then replace the silica gel desiccant 36 and clean the impurities blocked by the filter screen 35. When it is necessary to adjust the height of the box body 1 and other structures, the two second electric telescopic rods 55 in the lifting buffer device 5 are activated, thereby driving the connecting frame 58 to move through the two connecting plates 56 and the two second buckles 57, thereby adjusting the height of the box body 1 and other structures. The damper 52 and the elastic rubber frame 54 between the support plate 51 and the bottom plate 53 can buffer external vibrations.

[0046] Although embodiments of the invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the invention, the scope of which is defined by the appended claims and their equivalents.
