[0003] However, oxygen needs to be filtered through a filter to remove impurities and dust. After long-term use, a lot of dust will accumulate on the surface of the filter plate, which will reduce the filtering efficiency of the filter plate.

[0025] See also Figures 1 to 5 , the utility model provides a technical solution:

[0026] A medical oxygen filtering mechanism comprises a filter box 1, a connecting pipe 6 and a humidifying box 9. The filter box 1 and the humidifying box 9 are connected by the connecting pipe 6. An air inlet head 2 is arranged on the side of the filter box 1 away from the connecting pipe 6. Two mounting grooves 3 are arranged on the side wall of the filter box 1 perpendicular to the air inlet head 2. A first filter plate 4 is arranged inside the mounting groove 3 close to the air inlet head 2, and a second filter plate 5 is arranged inside the other mounting groove 3.

[0027] The first filter plate 4 and the second filter plate 5 are respectively installed inside the installation groove 3, and the first filter plate 4 and the second filter plate 5 are respectively slidably connected to the installation groove 3, so that the cleaning staff can regularly take out the first filter plate 4 and the second filter plate 5 for cleaning.

[0028] The diameter of the filter holes on the side wall of the second filter plate 5 is smaller than the diameter of the filter holes on the side wall of the first filter plate 4, and both the first filter plate 4 and the second filter plate 5 are provided with double-layer filter screens, and activated carbon is provided inside the second filter plate 5. By setting the diameter of the side wall of the second filter plate 5 smaller than the diameter of the filter holes on the side wall of the first filter plate 4, the oxygen that generally enters the filter box 1 through the air intake head 2 is isolated from dust by the first filter plate 4, and other impurities are absorbed by the second filter plate 5 and the activated carbon inside. The double-layer filtration ensures the quality of the oxygen.

[0029] The side walls opposite to the filter box 1 and the humidification box 9 are fixedly installed with the two ends of the connecting pipe 6 respectively. The middle part of the connecting pipe 6 is provided with an air pump 7. The air pump 7 is installed on the surface of the support plate 8. The two ends of the support plate 8 are fixedly installed with the side walls opposite to the filter box 1 and the humidification box 9 respectively. The filter box 1 and the humidification box 9 are connected by providing the connecting pipe 6, so that the oxygen filtered by the filter box 1 is pumped into the humidification box 9 through the air pump 7, and is humidified so that the patient can absorb it comfortably.

[0030] A plurality of circular holes 11 are provided on the top of the humidification box 9, and the inner walls of the plurality of circular holes 11 are fixedly mounted on the side walls of the nozzles of the spray tube 12. The water inlet pipe of the spray tube 12 is fixedly mounted on the water tank 13. The water tank 13 is arranged on the side wall of the humidification box 9. A water inlet 14 is provided on the surface of the water tank 13. The water tank 13 is arranged on the side wall of the humidification box 9, and a spray tube 12 is arranged on the top of the water tank 13. The nozzle at the end of the spray tube 12 penetrates the circular holes 11 on the surface of the humidification box 9 and is arranged above the interior of the humidification box 9, so as to humidify the filtered oxygen inside the humidification box 9, and then output it through the air outlet 10 for the convenience of patients.

[0031] A slide groove 16 is provided on one side of the top surface of the humidifying box 9, and a square groove 17 is provided on the side wall of the slide groove 16 close to the inside. The inner walls of the slide groove 16 and the square groove 17 are respectively slidably connected to the wiper strip 15, and the side wall of the wiper strip 15 is slidably connected to the inner wall of the humidifying box 9.

[0032] By arranging the wiper strip 15 to slide inside the humidification box 9, the end of the wiper strip 15 is slidably connected to the slide groove 16 and the square groove 17, so that the end of the wiper strip 15 exposed outside the humidification box 9 can be easily moved manually, so that the wiper strip 15 slides on the inner wall of the humidification box 9, scrapes off the water vapor on the inner wall of the humidification box 9, and then discharges it through the drainage groove 19 at the bottom of the humidification box 9, thereby ensuring the humidified environment inside the humidification box 9.

[0033] The slide groove 16 and the square groove 17 are interconnected in an L shape, and sealing sheets 18 are provided on the inner walls of the slide groove 16 and the square groove 17. The sealing sheets 18 are set to rubber material. The slide groove 16 and the square groove 17 are interconnected and L-shaped, and the inner walls of the slide groove 16 and the square groove 17 are provided with sealing sheets 18 to ensure the sealing of the humidification environment inside the humidification box 9, thereby avoiding leakage of filtered oxygen inside the humidification box 9 and affecting patient use.

[0034] The upper middle part of the wiper strip 15 is not through and the diameter of the gap is larger than the diameter of the nozzle at the end of the spray tube 12. By setting the upper middle part of the wiper strip 15 not through and the diameter of the gap is larger than the diameter of the nozzle at the end of the spray tube 12, it is possible to avoid the wiper strip 15 colliding with the nozzle when sliding inside the humidification box 9, thereby causing damage to the nozzle.

[0035] Spiral grooves are respectively provided on the side walls of the air inlet head 2 and the air outlet head 10. By providing spiral grooves on the side walls of the air inlet head 2 and the air outlet head 10, it is convenient to install the external tube on the side walls of the air inlet head 2 and the air outlet head 10, thereby increasing friction and preventing the external tube from falling off.
