[0047] Working principle:

[0048] When in use, oxygen is input into the heating chamber 4 inside the heat exchange shell 1 through the air inlet pipe 7, and the oxygen is heated by the heating rod 8. The heated oxygen enters the gas collecting pipe 29 through the exhaust pipe 28, and the oxygen in the gas collecting pipe 29 enters the compressor 2 through the connecting pipe 30. The pressure and concentration of the oxygen are increased by the compressor 2, and finally the oxygen is passed into the oxygen cylinder through the connecting pipe 30.

[0049] After the oxygen is heated, the personnel can loosen the fastening bolts 33 to remove the fastening bolts 33 from the heat exchange shell 1, and then remove the air inlet pipe 7 and the heating rod 8 on the positioning plate 6. When the heating rod 8 is pulled out from the heat exchange shell 1, the cleaning agent in the liquid storage shell 23 is conveniently passed into the shunt pipe 25 through the drain pipe 24 and the telescopic hose 35. The cleaning agent in the shunt pipe 25 will be sprayed on the heating rod 8 to be pulled out through multiple nozzles 26, and the impurities on the heating rod 8 will be dissolved by the agent.

[0050] When the driving gear 13 rotates, it drives the auxiliary gear 40 to rotate. When the auxiliary gear 40 rotates, it drives the cam 37 to rotate by using the auxiliary rotating rod 36. When the cam 37 rotates to a specified angle, it pushes the U-shaped rod 41 back and forth. Then, the elastic force of the spring 43 is used to restore the U-shaped rod 41 that has been pushed a certain distance to its original position. Then, the second tooth block 42 on the U-shaped rod 41 is meshed with the driven gear 38 on the shunt pipe 25, so that the shunt pipe 25 is in a swinging state, so that the medicine is evenly sprayed on the heating rod 8, thereby improving the cleaning effect of the heating rod 8.

[0051] At this time, when the heating rod 8 is pulled out, the dissolved impurities on the heating rod 8 will come into contact with the cleaning brush 10, and at the same time, the motor 11 in the driving assembly will drive the driving gear 13 to rotate. Through the meshing of the driving gear 13 and the first gear 14, the first gear 14 will drive the second gear 15 to rotate through the driving shaft 12, and then the second gear 15 will mesh with the first tooth block 19 on the driving ring 18. The driving ring 18 will drive the cleaning brush 10 to rotate under the limit of the mounting ring 17, and the cleaning brush 10 will be used to clean the impurities on the heating rod 8, thereby avoiding the influence and damage of the impurities on the heating rod 8. At the same time, there is no need for personnel to manually clean the heating rod 8, so that personnel can more easily maintain and clean the oxygen cylinder rewarming and oxygen supply device.

[0052] It should be noted that, in this article, relational terms such as first and second, etc. are only used to distinguish one entity or operation from another entity or operation, and do not necessarily require or imply any such actual relationship or order between these entities or operations. Moreover, the terms "include", "comprise" or any other variants thereof are intended to cover non-exclusive inclusion, so that a process, method, article or device including a series of elements includes not only those elements, but also other elements not explicitly listed, or also includes elements inherent to such process, method, article or device.
