[0022] 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.

[0023] Specific implementation examples are given below.

[0024] Please see Figures 1-8 The present invention provides an oxygen supply and humidification device with condensate recovery function, including a humidification bottle 1, an oxygen supply pipe 2 is fixedly connected to the lower right side of the humidification bottle 1, a fixing frame 3 is fixedly connected to the middle of the outer surface of the humidification bottle 1, a bottle cap 4 is threadedly connected to the upper outer surface of the humidification bottle 1, a threaded hole 41 is opened in the middle of the upper end of the bottle cap 4, an adjustment structure 5 is threadedly connected inside the threaded hole 41, and a recovery mechanism 6 is fixedly connected to the upper front side of the humidification bottle 1.

[0025] Further, such as Figure 1 and Figure 8 As shown, the recycling mechanism 6 includes a semi-circular cavity shell 61. A first connecting pipe 62 is fixedly connected to the upper rear side of the semi-circular cavity shell 61. A second connecting pipe 63 is fixedly connected to the upper front side of the semi-circular cavity shell 61. A baffle 64 is fixedly connected to the middle of the upper inner wall of the semi-circular cavity shell 61. A third connecting pipe 65 is fixedly connected to the middle lower side of the semi-circular cavity shell 61. A connecting cap 66 is fixedly connected to the lower part of the third connecting pipe 65. A collection bottle 67 is threadedly connected inside the connecting cap 66. An exhaust pipe 68 is fixedly connected to the upper outer surface of the collection bottle 67.

[0026] With the above solution: when the device is in use, the humidified oxygen is discharged and passes through the semi-circular cavity 61 in the recovery mechanism 6. The oxygen will be blocked by the baffle 64 and the larger water molecules contained inside will condense. The condensed liquid will drip down and be collected in the collection bottle 67, preventing water molecules in the oxygen from condensing and spraying out in the oxygen tube during oxygen supply, which would cause discomfort to the user.

[0027] Further, such as Figures 1-4 As shown, a connecting ring 11 is fixedly connected to the upper part of the outer surface of the humidifier bottle 1. The humidifier bottle 1 is threadedly connected to the bottle cap 4 through the connecting ring 11. A fixing block 12 is fixedly connected to the upper right side of the humidifier bottle 1. A first fixing hole 13 is opened on the upper right side of the fixing block 12. A second fixing hole 14 is opened on the lower right side of the humidifier bottle 1. A third fixing hole 15 is opened on the upper front side of the humidifier bottle 1. The third fixing hole 15 is inserted and fixedly connected to the second connecting pipe 63.

The L-shaped pipe 21 extends into the interior of the humidifier bottle 1. Multiple air outlet holes 22 are distributed in a ring at equal intervals on the outer surface of the L-shaped pipe 21 at the position inside the humidifier bottle 1.

[0028] The above solution involves opening multiple air outlets 22 at the end of the oxygen supply pipe 2. When supplying oxygen, the dense array of small air outlets 22 makes the oxygen discharged into the humidification bottle 1 more abundant, which increases the contact area between oxygen and water and improves the efficiency of oxygen humidification.

[0029] Further, such as Figure 1 , Figure 5 and Figure 6 As shown, the adjusting structure 5 includes a worm gear 51, which is threaded into a threaded hole 41. Limiting rings 54 are fixedly connected to both the upper and lower parts of the worm gear 51. The two limiting rings 54 are located at the upper and lower parts of the bottle cap 4, respectively. A first fixing rod 52 is fixedly connected to the upper side of the upper limiting ring 54, and a second fixing rod 53 is fixedly connected to the lower side of the lower limiting ring 54. Three filter discs 55, evenly spaced on their upper sides, are fixedly connected to the outer surface of the second fixing rod 53. The three filter discs 55 are externally... All are fitted to the inside of the humidifier bottle 1. An adjustment knob 56 is fixedly connected to the upper part of the first fixing rod 52. The filter plate 55 includes a fixing plate 551. The upper part of the fixing plate 551 is provided with a fourth fixing hole 552 and multiple air vents 553 distributed in a circular array at equal distances. The fourth fixing hole 552 is located between the multiple air vents 553 and is inserted and fixedly connected to the second fixing rod 53. An annular cotton pad 554 is snapped into the inside of the fixing plate 551. A separation slit is provided on the upper part of the annular cotton pad 554.

[0030] Through the above scheme: When using the device, the height of the three filter discs 55 in the adjustment structure 5 can be adjusted according to the user's oxygen humidity requirements. The more filter discs 55 located below the third fixed hole 15 for air outlet, the more humidity in the humidified oxygen can be adsorbed, thus reducing the degree of oxygen humidification. The more filter discs 55 located above the third fixed hole 15, the more water molecules in the humidified oxygen can be, thus achieving effective control of oxygen humidity and enabling the device to be used by patients with different humidity requirements.

[0031] Further, such as Figure 1 and Figure 7 As shown, the mounting bracket 3 includes a mounting plate 31. A connecting block 32 is fixedly connected to the middle of the front side of the mounting plate 31. Two mounting holes 33 are opened on the left and right sides of the front side of the mounting plate 31. A slot 34 is opened on the upper part of the connecting block 32. A locking block 35 is engaged inside the slot 34. A fixing ring 36 is fixedly connected to the front of the locking block 35. The fixing ring 36 is fixedly connected to the middle of the outer surface of the humidifying bottle 1.

[0032] With the above solution: by setting the fixing frame 3 into a two-part structure, before the device is used, the mounting plate 31 can be installed and fixed by fixing nails, and the fixing ring 36 can be fixedly connected to the humidifying bottle 1. When the device is used, the humidifying bottle 1 can be directly connected to the locking block 35 at the rear of the fixing ring 36 and the locking groove 34 at the front of the mounting plate 31, so as to realize the quick installation of the humidifying bottle 1.

[0033] A method of using an oxygen supply and humidification device with condensate recovery function, for the instruction manual of the aforementioned oxygen supply and humidification device with condensate recovery function, characterized in that it includes at least the following steps: Step 1, Device Installation: Add an appropriate amount of purified water into the humidifier bottle 1, connect the bottle cap 4, and fix the humidifier bottle 1 in place using the fixing bracket 3. Then connect the oxygen supply tube 2 to the oxygen source, and then connect the recovery mechanism 6 to the oxygen tube. Step 2, Oxygen Humidity Adjustment: When the oxygen humidity content requirement is high, adjust the three filter discs 55 in the adjustment structure 5 to the upper part of the third fixing hole 15 according to the humidity content requirement, reduce the contact between oxygen and filter discs 55, and maintain the humidity content in the oxygen. When the oxygen humidity content requirement is low, adjust the three filter discs 55 in the adjustment structure 5 to the lower part of the third fixing hole 15 according to the humidity content requirement, increase the contact between oxygen and filter discs 55, filter out water molecules in oxygen through filter discs 55, and reduce the humidity content in oxygen. Step 3, Liquid Recovery: The oxygen entering the humidification bottle 1 enters the semi-circular cavity shell 61 in the recovery mechanism 6 after humidification. The oxygen entering the semi-circular cavity shell 61 will collide with the baffle 64, causing the larger water molecules contained in the oxygen to condense in advance and fall downwards, and be collected in the collection bottle 67.

[0034] Working principle: First, add an appropriate amount of purified water to the humidifier bottle 1, then connect the oxygen supply tube 2 to the oxygen source, connect the second connecting tube 63 in the recovery mechanism 6 to the oxygen tube, and finally engage and fix the humidifier bottle 1 with the slot 34 in the connecting block 32 fixed on the wall or other object by the locking block 35 fixed to the back of the fixing ring 36, and it can then be used. During use, the oxygen humidity can be controlled by adjusting the regulating structure 5 according to the user's requirements for oxygen humidity. When the user needs a higher oxygen humidity, the three filter discs 55 in the regulating structure 5 can be adjusted as high as possible to the upper part of the third fixed hole 15 connected to the recovery mechanism 6 to increase the oxygen humidity. When the user needs a lower oxygen humidity, the three filter discs 55 in the regulating structure 5 can be adjusted to the lower part of the third fixed hole 15 so that the three filter discs 55 can filter out the water vapor in the humidified oxygen to reduce the water molecule content in the oxygen. Then, oxygen enters the recovery mechanism 6 through the third fixing hole 15. In the semi-circular cavity shell 61 of the recovery mechanism 6, the oxygen collides with the baffle 64, causing the larger water molecules contained in the oxygen to condense in advance and fall down and be collected in the collection bottle 67 at the bottom of the semi-circular cavity shell 61. The subsequent oxygen is discharged into the oxygen pipe through the second connecting pipe 63 to supply oxygen to the user.

[0035] The foregoing has shown and described the basic principles, main features, and advantages of the present invention. Those skilled in the art should understand that the present invention is not limited to the above embodiments. The embodiments and descriptions in the specification are merely illustrative of the principles of the invention.
