[0038] As shown in the figure, Figure 6 and 7 As shown in the figure, the outer surface of the lower end of the movable pipe 20 is fixedly connected with a connecting pipe 39, the inner surface of the connecting pipe 39 is fixedly connected with a mounting plate 37, the mounting plate 37 is rotatably connected with a movable rod 27, the outer surface of the movable rod 27 is fixedly connected with a baffle 28, the outer surface of the lower end of the baffle 28 is fixedly connected with a traction strip 29, and the lower end of the traction strip 29 is fixedly connected with the sealing ball 32.

In the movement of the sealing ball 32 through the sliding connection with the movable rod 27, the movable rod 27 can guide the sealing ball 32 to some extent, so that the sealing ball 32 moves more stably.

[0041] When the oxygen is humidified, the oxygen is injected downward through the air guide pipe 19, and the drainage seat 31 on the upper side of the sealing seat 30 can collect the oxygen to some extent, thereby increasing the flow rate of the oxygen in the drainage seat 31 to some extent.

[0045] When the oxygen enters the inside of the fixed sleeve 18, part of the oxygen will enter the inside of the support pipe 13 under the action of gas pressure, at this time the ball bearings 17 in the inside of the support pipe 13 move upward under the pushing action of the oxygen, when the gas pressure in the inside of the fixed sleeve 18 increases, the ball bearings 17 will move downward in the inside of the support pipe 13 by a distance, according to the position change of the sealing spherical body 32 in the inside of the support pipe 13, the gas pressure in the inside of the fixed sleeve 18 can be intuitively fed back, at the same time the adjusting valve 15 extends to the inside of the limiting seat 42, which can adjust the oxygen injection pressure, the limiting seat 42 in the inside of the support pipe 13 can limit the ball bearings 17 to a certain extent, so as to prevent the ball bearings 17 from falling from the inside of the support pipe 13, by setting the gas guide assembly, the oxygen enters the inside of the humidifying tank 12 for humidification treatment at a proper pressure, so as to improve the convenience and stability of the oxygen humidifying device during the working process.

[0050] The outer surface of the movable rod 27 is fixedly connected with a top rod 36, the upper end of the outer surface of the top rod 36 is arc-shaped, the arc-shaped top rod 36 is matched with the guide groove 34, the outer surface of the spoiler 21 is provided with a mesh 40, the outer surface of the lower side of the connecting pipe 39 is fixedly connected with a limiting ring 38, and the limiting ring 38 is located on the lower side of the spoiler 21.

[0051] By adopting the technical scheme, the connecting pipe 39 is used for slidingly supporting the spoiler 21, the limiting ring 38 on the lower side of the connecting pipe 39 can limit the spoiler 21 to a certain extent, thereby reducing the risk of the spoiler 21 sliding off the surface of the connecting pipe 39, and the connecting pipe 39 is rotationally supported on the movable rod 27 through the mounting plate 37, the movable rod 27 drives the jack 36 to move synchronously in the process of rotation, the jack 36 is in contact with the lower surface of the moving sleeve 41 in the process of rotation, the moving sleeve 41 is provided with a plurality of groups of arc-shaped guide grooves 34 on the lower surface, when the jack 36 moves into the guide groove 34, the moving sleeve 41 moves downward under the action of the spoiler 21 and its own gravity, with the continuous rotation of the jack 36, when the jack 36 moves from the inside of the guide groove 34 to the lower side of the moving sleeve 41, the jack 36 pushes the moving sleeve 41 and the spoiler 21 to move upward, with the up-and-down reciprocating movement of the spoiler 21, the speed of the bubbles in the purified water flowing upward can be slowed down to a certain extent, so that the oxygen has enough time to mix and contact with the purified water, thereby effectively improving the content of water in the oxygen, and further improving the humidification quality of the oxygen, the mesh holes 40 uniformly arranged on the surface of the spoiler 21 can effectively increase the contact area with the purified water, and in the process of up-and-down reciprocating movement of the spoiler 21, the mesh holes 40 can make the purified water flow irregularly, thereby further improving the mixing efficiency of the oxygen and the purified water.

[0053] When the oxygen humidifying device works, oxygen is injected into the fixed sleeve 18 through the air inlet pipe 14, and the oxygen enters the air guide pipe 19 through the fixed sleeve 18. In the process of flowing downward, the sealed ball 32 is pushed, so that the sealed ball 32 enters the movable pipe 20 under the action of the gas pressure. When the sealed ball 32 enters the movable pipe 20, the oxygen flows downward from the gap between the sealed ball 32 and the movable pipe 20, so that the oxygen is injected smoothly. When the pure water in the humidifying tank 12 flows upward through the air guide pipe 19, the sealed ball 32 moves upward under the action of the buoyancy of the pure water, so that the sealed ball 32 and the sealing seat 30 are closely attached, thereby effectively reducing the reflux of the pure water in the air guide pipe 19. The ball bearings 17 in the support pipe 13 move upward under the action of the oxygen. According to the position change of the sealed ball 32 in the support pipe 13, the gas pressure in the fixed sleeve 18 can be intuitively fed back. When the oxygen is injected into the fixed sleeve 18 through the air inlet pipe 14, the oxygen blows the paddle 25, and the installation pipe 26 and the movable rod 27 are driven to rotate by the paddle 25. In the process of rotating, the flow plate 23 mixes and stirs the oxygen and the pure water, so that the oxygen and the pure water can be fully mixed and contacted, thereby effectively improving the humidity content of the oxygen. When the jack 36 moves from the guide groove 34 to the lower side of the moving sleeve 41, the jack 36 pushes the moving sleeve 41 and the spoiler 21 to move upward. With the up-down reciprocating motion of the spoiler 21, the speed of the bubbles in the pure water flowing upward can be slowed down to a certain extent, so that the oxygen has enough time to mix and contact with the pure water, thereby effectively improving the water content in the oxygen.
