[0016] Example 1

[0017] like Figure 1-2The dehumidification device of an oxygen generator shown includes a dehumidification box 1, an air inlet pipe 2 and a partition 12. The air inlet pipe 2 is connected to one side of the dehumidification box 1. An air inlet valve 9 is provided on the air inlet pipe 2. The gas produced by the oxygen generator is passed into the air inlet pipe 2. The air inlet valve 9 is opened to allow the gas to enter the interior of the dehumidification box 1. An air outlet valve 16 is provided on the partition 12. The end of the air outlet valve 16 is connected to a heating pipe 17. The partition 12 is connected to the inner wall of the dehumidification box 1. The partition 12 divides the interior of the dehumidification box 1 into a heating chamber 10 and a cooling chamber 13. The air outlet valve 16 remains closed when the gas is heated to prevent the gas from escaping into the cooling chamber 13. A heating component for heating the gas is provided in the heating chamber 10, a cooling component for cooling the gas is provided in the cooling chamber 13, and a filtering component for filtering the gas is provided on the outside of the cooling chamber 13.

[0018] In this embodiment, the heating component includes a heating device 10 and a heating tube 17. The heating device 10 is connected to the inner wall of the dehumidification box 1. One side of the heating tube 17 is connected to the inner wall of the dehumidification box 1. The other side of the heating tube 17 is connected to the partition 12. The interior of the heating tube 17 is connected to the air inlet pipe 2. When the gas enters the heating tube 17, the heating device 11 is turned on. The heating device 11 can use an electric heater. The heating device 11 increases the temperature in the heating chamber 10, thereby increasing the gas temperature and making the water vapor molecules more active. The cooling component includes a liquid inlet pipe 3, a liquid outlet pipe 4, a water storage tank 8 and a cooling pipe 14. The liquid inlet pipe 3 and the liquid outlet pipe 4 are both connected to the outer wall of the dehumidification box 1. The cooling pipe 14 is connected to the inner top wall of the cooling chamber 13. The water storage tank 8 is connected to the inner bottom of the cooling chamber 13. The wall, the coolant is passed into the liquid inlet pipe 3, the cooling pipe 14 is composed of multiple groups of tortuous pipes, the liquid inlet pipe 3 and the liquid outlet pipe 4 are respectively arranged at both ends of the cooling pipe, the coolant flows along the cooling pipe 14, and the heated gas enters the cooling bin 13 through the outlet valve 16. Since the density of water vapor is lower than that of oxygen, the water vapor at the top will quickly cool down and liquefy after contacting the outer wall of the cooling pipe 14 to form water droplets. The water droplets fall into the water storage tank 8 for storage, and can be dumped by simply pulling out the water storage tank 8, which is very convenient. The gas produced by the oxygen generator is first heated after entering the dehumidification box 1 to make the water vapor molecules more active, and then enters the cooling bin 14. The high-temperature water vapor will quickly liquefy and form water droplets when it contacts the cooling pipe 14 with a lower temperature, which can reduce the moisture content in the gas.

[0019] Example 2

[0020] A further improvement on the basis of Example 1 is that Figure 2-3A dehumidification device of an oxygen generator is shown, and the filtering component includes a fan 5, a filter tube 6 and an air outlet hopper 7. The fan 5 is connected to the side of the dehumidification box 1 close to the cooling bin 13. One end of the filter tube 6 is detachably connected to the fan 5, and the other end of the filter tube 6 is connected to the air outlet hopper 7. An adsorbent 15 for adsorbing moisture and impurities is provided in the filter tube 6. The adsorbent 15 can be selected as absorbent cotton. After the gas is cooled, the fan 5 is turned on to suck the gas out of the cooling bin 13. When the gas passes through the filter tube 6, the residual moisture and impurities therein will be absorbed by the adsorbent 15, so that the oxygen purity in the gas is further improved.

[0021] The process flow and working principle of the utility model are as follows: when dehumidifying the oxygen produced by the oxygen concentrator, the gas is first introduced into the air inlet pipe 2, and then the air inlet valve 9 is opened, the gas enters the heating tube 17, and the heating device 11 is turned on to heat the gas. At this time, the air outlet valve 16 is kept closed. When the gas temperature rises to a certain temperature, the air outlet valve 16 is opened again, and the gas enters the cooling bin 13. Coolant is introduced into the liquid inlet pipe 3. When the high-temperature water vapor contacts the surface of the cooling tube 14, the temperature drops rapidly to form water droplets. Then the fan 5 is turned on to suck the cooled gas out of the dehumidification box 1. The residual moisture in the gas will be adsorbed by the adsorbent 15 in the filter tube 6, thereby reducing the water vapor and impurity content in the gas, which has the effect of improving the purity and quality of the oxygen produced by the oxygen concentrator.

[0022] Finally, it should be noted that the above is only a preferred embodiment of the present invention and is not intended to limit the present invention. Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art can still modify the technical solutions described in the aforementioned embodiments or make equivalent substitutions for some of the technical features therein.
