[0044] During use, since the pull rod 204 is eccentrically arranged at one end of the ventilation tube 200, the ventilation tube 200 can only slide in the cylindrical groove 101 and cannot rotate. The operator can control the sliding movement of the ventilation tube 200 through the pull rod 204 and thus switch the air path.

[0045] Specifically, the No. 1 protrusion 201b is provided on the No. 1 piston 201, and the No. 1 conical surface 201c is provided on the No. 1 piston 201; the No. 2 protrusion 202b is provided on the No. 2 piston 202, and the No. 2 conical surface 202c is provided on the No. 2 piston 202; the No. 1 air intake groove 201a is provided on the No. 1 protrusion 201b, and the No. 2 air intake groove 202a is provided on the No. 2 protrusion 202b.

[0046] Furthermore, the first protrusion 201b and the second protrusion 202b are staggered on the outer wall of the vent pipe 200, and the staggered angle is less than one hundred and eighty degrees.

[0047] The first piston 201 is provided with a first guide surface 201 d ; the second piston 202 is provided with a second guide surface 202 d .

[0048] Preferably, a liquid collecting box 400 is provided in the housing 100, and a central collecting area 401 and two side collecting areas 402 are provided in the liquid collecting box 400; a first drain trough 106, a second drain trough 107, and a third drain trough 108 are provided in the cylindrical tank 101;

[0050] It should be noted that the two side collection areas 402 are C-shaped structures with the openings facing upward, and the middle collection area 401 is arranged at the opening of the C-shaped structure. Two side drainage ports 402a are provided in the two side collection areas 402, and a middle drainage port 401a is provided in the middle collection area 401. Both the two side drainage ports 402a and the middle drainage port 401a are sealed by sealing plugs.

[0051] The rest of the structure is the same as that of Example 1.

[0052] Reference Figure 7 , set the area of ​​the cylindrical groove 101 located on the left side of the No. 1 piston 201 as area Q, the area between the No. 1 piston 201 and the No. 2 piston 202 as area P, and the area on the right side of the No. 2 piston 202 as area R.

[0053] Reference Figure 8 This is the first working mode, which reduces the space of area R and increases the space of area Q, so that the No. 1 docking port 102 and the No. 2 docking port 103 are connected through area Q for oxygen delivery; the No. 3 docking port 104 and the No. 4 docking port 105 are connected through area P for delivering the patient's exhaled gas.

[0054] Reference Figure 9 This is the second working mode, which increases the space of area R and reduces the space of area Q, so that the No. 2 docking port 103 and the No. 1 air inlet groove 201a are aligned, and the No. 3 docking port 104 and the No. 2 air inlet groove 202a are aligned. At this time, the No. 2 docking port 103 and the No. 3 docking port 104 are connected, and the gas can pass through the No. 2 docking port 103, the No. 1 air inlet groove 201a, the guide hole 203, the No. 2 air inlet groove 202a, and the No. 3 docking port 104 in sequence to transport the patient's exhaled gas, while the No. 1 docking port 102 and the No. 4 docking port 105 are connected by area P for transporting oxygen.

[0055] During operation, medical staff can control the sliding of piston No. 1 201 and piston No. 2 202 by pulling the pull rod 204. Due to the setting of drainage trough No. 106, drainage trough No. 3 108 and collection areas 402 on both sides, and the setting of guide hole 203, when piston No. 1 201 and piston No. 2 202 slide, the gas in area Q and area R can be interchanged, which is convenient for medical staff to operate the pull rod 204.

[0056] The arrangement of the No. 1 protrusion 201b, the No. 2 protrusion 202b, the No. 1 conical surface 201c and the No. 2 conical surface 202c can make the structure more compact and reduce the volume of the equipment, and can achieve a better guiding effect in conjunction with the No. 1 guide surface 201d and the No. 2 guide surface 202d, thereby facilitating the guidance of gas flow.

[0057] Due to environmental factors, condensed water will appear in the pipeline. The channel switching mechanism M is placed on the ground when in use. Therefore, a V-shape is formed between the No. 1 docking port 102, the No. 3 docking port 104 and the No. 2 docking port 103 and the No. 4 docking port 105, which can guide the condensed water to flow into the cylindrical groove 101 of the shell 100 under the action of gravity. Due to the action of gravity, the condensed water located in the area Q is discharged into the collection areas 402 on both sides through the No. 1 drainage groove 106, the condensed water located in the area P is discharged into the middle collection area 401 through the No. 2 drainage groove 107, and the condensed water located in the area R is discharged into the collection areas 402 on both sides through the No. 3 drainage groove 108, which can facilitate the collection and isolation of the condensed water to prevent the condensed water from accumulating in the pipeline and breeding bacteria.

[0058] Reference Figure 4 The guide hole 203 is an arc-shaped structure. The arc-shaped setting is convenient for guiding the flow of condensed water and collecting the condensed water. Figure 5 The No. 1 protrusion 201b and the No. 2 protrusion 202b are staggered on the outer wall of the vent pipe 200, and the staggered angle is less than one hundred and eighty degrees. The cross-sections of the No. 1 air inlet groove 201a and the No. 2 air inlet groove 202a are fan-shaped, which can form a V-shaped state, making it convenient for the condensed water to flow into the cylindrical groove 101, and facilitating the collection and separation of the condensed water.
