The upper end of the first connecting sleeve 203 is fixedly connected with the lower end of the first sealing plug 204. The inner side of the first connecting sleeve 203 is sleeved with the first slide column 202. The first slide column 202 and the first connecting sleeve 203 are in sliding connection. The upper end of the first slide column 202 is fixedly installed with the spring 206 for expansion and contraction. The upper end of the spring 206 is fixedly installed with the second sealing plug 207 for plugging the lower end of the dropper 205. The lower end of the first slide column 202 is fixedly installed with the float 201 for sinking and floating.

[0027] Please refer to Figures 6-7 In the embodiment, the anti-backflow assembly comprises a check valve 301 and a connecting head 302. The Y-shaped connecting pipe at the upper end of the water accumulation cup 8 is detachably installed with the check valve 301 for preventing water backflow between the two ends and the pipeline module 7. The two ends of the check valve 301 are fixedly connected with the connecting heads 302 for mutual insertion with the pipeline module 7. The inside of the check valve 301 is provided with a one-way membrane for preventing water backflow in the water accumulation cup 8. The bottom of the water accumulation cup 8 is fixedly installed with the elastic rebound plug 9 for water drainage. The elastic rebound plug 9 is in a tapered structure with a narrow upper end and a wide lower end. The upper end and the lower end of the elastic rebound plug 9 are respectively provided with the outlet 11 and the inlet 10 penetrating each other. The outlet 11 is in a closed state in a normal state. The water in the water accumulation cup 8 is sucked out by pushing the ejection structure into the inlet 10 to open the outlet 11.

[0028] In the working process, first, the pipeline module 7 is connected with the host 1, the humidification tank 4 and the water accumulation cup 8. The dropper 205 on the water adding assembly is connected with the corresponding water adding equipment. It is ensured that the first sealing plug 204 on the water adding assembly of the humidification tank 4 is in sealed connection with the humidification tank 4. Then, the anti-backflow assembly at the lower end of the water accumulation cup 8 is in sealed connection with the corresponding water collecting container.

[0029] Then, the end of the pipeline module 7 away from the host 1 is connected with the patient for breathing.

[0030] In use, water is automatically added into the humidification tank 4 by the water adding assembly. When the float 201 is below the water filling line, the internal water filling valve is automatically opened, the second sealing plug 207 is separated from the lower end of the dropper 205, and the sterile water is injected into the humidification tank 4 along the flow guide groove 210 inside the first connecting sleeve 203. If the float 201 is already at the scale line, the water filling valve is automatically closed. The buoyancy of the water makes the first slide column 202 slide upward along the inner wall of the first connecting sleeve 203, and the spring 206 is synchronously moved upward, so that the second sealing plug 207 at the upper end of the spring 206 is inserted into the lower end of the dropper 205, and the humidification water stops being continuously injected.

[0031] In use of the pipeline module 7, the generated water first passes through the check valve 301 of the anti-backflow assembly, and then enters the water accumulation cup 8. The one-way membrane inside the check valve 301 prevents the water from flowing back, and also ensures the sealing of the water accumulation cup 8.

[0032] Finally, when the water in the water accumulation cup 8 is full, the water is sucked out of the water accumulation cup 8 by the external water suction structure. The suction pipe of the water suction device is inserted into the inlet 10 of the elastic rebound plug 9 at the bottom of the water accumulation cup 8, and then the outlet 11 of the elastic rebound plug 9 is forced to be opened, so that the water in the water accumulation cup 8 is sucked into the water suction device. After the water in the water accumulation cup 8 is completely sucked out, the suction pipe is pulled out, and the elastic rebound plug 9 rebounds to the initial sealing state, so that the water in the water accumulation cup 8 cannot flow out.

[0033] Through the above steps, the water adding assembly with the sealed float 201 structure built-in the humidification tank 4 can connect the sterile water and the humidification tank 4 through the sealed pipeline, so as to continuously and accurately add the humidification water. The anti-backflow assembly with the anti-backflow check valve 301 structure at the upper end of the water accumulation cup 8 can automatically drain the water without unscrewing the water accumulation cup 8. During the drainage process, the check valve 301 can realize one-way drainage, so that the water accumulation cup 8 can always maintain a sealed state. The problems of short-term sealing loss in some specific operations during maintenance and use of the existing breathing machine pipeline are solved, such as completely opening the pipeline to add water when adding humidification water to the humidification tank 4 of the breathing machine pipeline, or using a disposable infusion tube to drip from the water adding port at the top of the humidification tank 4, which may cause an unsealed condition during the dripping process. When cleaning the water accumulation cup 8, the water accumulation cup 8 is usually unscrewed and tilted to drain the water in the breathing pipeline, which may also cause an unsealed condition.
