[0025] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0026] Combined with Figure 1-5 In this embodiment, a medical oxygen purification and filtering device includes a filter box 1, two filter tanks 11 are fixedly installed on both sides of the filter box 1, a top plate 12 is fixedly installed on the top of one side of the filter tank 11, and two clamping plates 13 are fixedly installed on the lower sides of the other side of the filter tank 11.

[0027] Specifically, the main body mechanism is the main structure of the medical oxygen purification and filtering device, and the clamping plate 13 is a structure for clamping and fixing the clamping block 4, thereby improving the stability of the medical oxygen purification and filtering device.

[0028] Two diversion mechanisms are fixedly installed on both sides of the filter box 1 , and the diversion mechanisms include: four ventilation pipes 2 installed on both sides of the filter box 1 , and a control valve 21 is fixedly installed on the outside of one side of the ventilation pipe 2 .

[0029] A manual switch 22 is fixedly installed on one side of the control valve 21 , and an automatic switch 23 is fixedly installed on the top of the control valve 21 .

[0030] A diverter valve 24 is fixedly installed on one side of the control valve 21 , and an oxygen pipeline 25 is fixedly installed on one side of the diverter valve 24 .

[0031] Specifically, the diversion mechanism is a structure used to divert oxygen when it enters the medical oxygen purification and filtering device, and to merge the oxygen when it is sent out after filtration, thereby improving the practicality of the medical oxygen purification and filtering device. The control valve 21 can be manually or automatically closed by the manual switch 22 and the automatic switch 23.

[0032] The top of the filter box 1 is movably connected with a sealing mechanism, and the sealing mechanism includes: a mounting plate 3 movably connected to the filter tank 11 , and four bolts 31 movably connected around the top of the mounting plate 3 .

[0033] A handle 32 is fixedly mounted on the top of the mounting plate 3 , and a sealing plate 33 is fixedly mounted on the bottom of the mounting plate 3 .

[0034] Specifically, the sealing mechanism is a sealing structure for the medical oxygen purification and filtering device. By screwing the four bolts 31 and then lifting the handle 32, the mounting plate 3 is lifted, thereby improving the practicality of the medical oxygen purification and filtering device.

[0035] A filter mechanism is fixedly installed at the bottom of the sealing mechanism, and the filter mechanism includes: a clamping block 4 installed at the bottom of the sealing plate 33, and a filter screen 41 is fixedly installed in the middle of one side of the clamping block 4.

[0036] The outer side of the filter screen 41 is movably connected to a filter element 42 , and the outer side of the filter element 42 is movably connected to an impurity filtering plate 43 .

[0037] Specifically, the filtering mechanism is a filtering structure used for the medical oxygen purification and filtering device. The larger particulate impurities in the oxygen are filtered through the filter mesh 41. The filter element 42 is an oxygen-specific structure for performing secondary filtering of the oxygen. Finally, the remaining impurities in the oxygen are filtered tertiary through the impurity filter plate 43, thereby improving the practicality of the medical oxygen purification and filtering device.

[0038] Working principle: First, oxygen is connected to the oxygen pipeline 25 on the right side of the medical oxygen purification and filtering device, and then diverted by the diverter valve 24 and sent to the two control valves 21, so that the oxygen is sent to the two filter tanks 11 inside the filter box 1 through the ventilation pipe 2 on the side of the control valve 21 for filtration. The oxygen passes through the hole in the middle of the clamping block 4 and is initially filtered by the filter mesh 41 to filter out larger particulate impurities in the oxygen. The filtered oxygen is filtered again by the filter element 42. The filter element 42 is a structure dedicated to oxygen filtration. After the oxygen is filtered twice by the filter element 42, the filtered oxygen is filtered three times by the impurity filter plate 43 to filter out the remaining impurities in the oxygen. The oxygen is filtered at the same time by the two filter tanks 11, thereby improving the filtering effect of the oxygen. The filter mesh 41, the filter element 42 and The impurity filter plate 43 is cylindrical in shape, thereby increasing the internal oxygen outlet holes and the filtering amount. The filtered oxygen passes through the ventilation pipe 2 on the other side, passes through the control valve 21, enters the diverter valve 24 and merges, and then is discharged from the oxygen pipeline 25. When the filter element 42 needs to be replaced during use, the two control valves 21 on one side are closed by the manual switch 22 or the automatic switch 23, so that the oxygen continues to be filtered through the filter tank 11 on the other side, the four bolts 31 on the closed side are turned, the handle 32 is lifted, and the filter structure is taken out for replacement. After replacement, the clamping block 4 is inserted into one side of the two clamping plates 13, and the top of the filter tank 11 is sealed by the sealing plate 33 at the bottom of the mounting plate 3, and the four bolts 31 are tightened to fix the mounting plate 3, so as to open the two control valves 21 on the replacement side to continue filtering the oxygen.
