DETAILED DESCRIPTION

[0022] Example 1

[0023] As Figures 1 to 4 shown, a kind of breathing machine automatic drainage condensate cup, including by lower and upper sequentially connected cup body 2 of barrel shape, disc-shaped cup cover 8 and Y-shaped pipe 6, two branch pipes of Y-shaped pipe 6 upper portion are connected with the pipeline of breathing machine. The cup body 2 is storage chamber 14, and the bottom of the cup body 2 is screw-connected with support seat 1 in central position, and the bottom of support seat 1 is liquid outlet pipe 12, and the top of support seat 1 is equipped with the vertical slide hole 13 who communicates with liquid outlet pipe 12, and the slide hole 13 is equipped with cylindrical piston 10, and the piston 10 is slidably connected with support seat 1.

[0024] The piston 10 has a downward-opening blind hole 15 at its center, and through holes 16 are evenly distributed along the circumferential and radial directions on its sidewalls. The piston 10 has a T-shaped cross-section, and the support base 11 has a cylindrical sealing platform 11 in the middle. The sliding hole 13 is located at the center of the sealing platform 11, and the top surface of the sealing platform 11 is flat. The bottom of the top of the piston 10 is in close contact with the top surface of the sealing platform 11. The through holes 16 are located in the middle and lower parts of the piston 10, and the top of the piston 10 has a movable float 3 for moving the piston 10 up and down.

[0025] A vertical pull rod 4 is fixedly connected to the top of the piston 10. The movable float 3 is slidably connected to the pull rod 4. The middle part of the cup lid 8 is connected to the Y-shaped tube 6. The pull rod 4 is slidably connected to the middle part of the cup lid 8. The middle part of the cup lid 8 has a liquid passage hole 17 around the pull rod 4, which connects the Y-shaped tube 6 to the liquid storage chamber 14. An annular impact block 5 is fixedly connected to the upper part of the pull rod 4. The impact block 5 is located between the movable float 3 and the cup lid 8.

[0026] A fixed float 9 is fixedly connected to the lower part of the pull rod 4, and the fixed float 9 is located between the movable float 3 and the piston 10. When the liquid in the reservoir 14 submerges the fixed float 9, the buoyancy force on the fixed float 9 is F1; when the liquid in the reservoir 14 submerges the movable float 3, the buoyancy force on the movable float 3 is F2. The sum of the weights of the pull rod 4, the impact block 5, the piston 10, and the fixed float 9 is G1, and the weight of the movable float 3 is G2. The downward pressure exerted by the liquid in the reservoir 14 on the piston 10 is F0. Therefore, G1 < F1 < (G1 + F0) and (F1 + F2) > (G1 + G2 + F0).

[0027] The working process of this utility model is as follows:

[0028] 1. The inside of the liquid storage chamber 14 is empty. Condensate flows into the liquid storage chamber 14 from the Y-shaped pipe 6, and the liquid level in the liquid storage chamber 14 gradually rises until the liquid level in the liquid storage chamber 14 is lower than the top of the fixed float 9. During this process, since F1 < (G1 + F0), the piston 10 is pressed tightly against the sealing platform 11, and no liquid flows out of the liquid outlet pipe 12.

[0029] 2. As the liquid level in the storage chamber 14 continues to rise, the movable float 3 floats upward along the pull rod 4. The movable float 3 is then blocked by the stop block 5, stopping its upward movement. The liquid level continues to rise until it covers the movable float 3. Since (F1+F2) > (G1+G2+F0), the pull rod 4 is pulled upward, and the stop block 5 is blocked by the cup lid 8. At this point, the storage chamber 14 and the blind hole 15 are connected by the through hole 16. The liquid in the storage chamber 14 flows sequentially through the through hole 16 and the blind hole 15 before entering the sliding hole 13, and then is discharged from the outlet pipe 12. The outlet pipe 12 can be connected to a flexible hose and connected to the storage container.

[0030] 3. As the liquid in the liquid storage chamber 14 is discharged, the liquid level gradually decreases until the piston 10 reattaches to the sealing platform 11, after which the above process is repeated.

[0031] As the pull rod 4 and the piston 10 have very small volumes, the buoyancy force on the pull rod 4 and the piston 10 is negligible in the above description.

[0032] Therefore, the condensed water in the liquid storage chamber 14 can be automatically discharged after reaching a certain amount without having to remove the cup 2, so that the inside and outside of the cup 2 are always isolated, thereby avoiding contamination of the surrounding environment or infection of personnel.

[0033] Embodiment 2

[0034] The difference between this embodiment and Embodiment 1 is that:

[0035] A flexible bellow 7 made of plastic is arranged between the Y-shaped tube 6 and the cup cover 8, the upper end of the bellow 7 is fixedly connected to the bottom of the Y-shaped tube 6, the lower end of the bellow 7 is fixedly connected to the center of the cup cover 8, the top end of the pull rod 4 is inserted into the lower end of the bellow 7, and the lower end of the bellow 7 is communicated with the liquid storage chamber 14 through the liquid passage 17.

[0036] After the bellow 7 is arranged, the cup 2 can always be kept vertical under the action of gravity, thereby ensuring the normal operation of the pull rod 4, the piston 10 and the movable float ball 3.

[0037] Embodiment 3

[0038] The difference between this embodiment and Embodiment 1 is that:

[0039] The support base 1 is a hollow conical platform, the sealing platform 11 is higher than the bottom of the cup 2, and the liquid outlet tube 12 is located at the bottom of the sealing platform 11.

[0040] The dirt with a larger specific gravity in the condensed water can be deposited around the sealing platform 11, thereby preventing the piston 10 from being blocked by the dirt.
