[0032] As shown in Figure 1 The utility model provides a water stop valve piece for intravenous infusion bottle, it includes:

[0033] Ring 101, made of hard material, the ring 101 central forming has an opening 1011, the opening 1011 around extends inwardly and forms a flange 1012, the flange 1012 is formed with a plurality of fixing holes 1013;And

[0034] Water stop piece 102, made of soft material, the outer periphery of the water stop piece 102 is inwardly recessed with a recess 1021 that can be combined with the flange, and the recess 1021 is provided with a plurality of fixing columns 1022 corresponding to the fixing holes 1013;

[0035] Wherein, the ring 101 and the water stop piece 102 are integrally formed by injection molding technology, so that the ring 101 and the water stop piece 102 are mutually embedded through a plurality of fixing columns 1022 passing through a plurality of fixing holes 1013 to form an integral whole.

[0036] In one embodiment, the ring 101 is formed by injection molding in advance, and the water stop piece 102 is integrally injection molded with the ring 101 in a mold. Further, the ring 101 is first injection molded in a mold, and then the water stop piece 102 is injection molded again in the same mold to form an integral body with the formed ring.

[0037] Referring to Figure 1 , the water stop valve piece 10 includes the ring 101 and the water stop piece 102. The ring 101 is made of hard plastic, and a through hole 1011 is formed in the center of the ring 101. A flange 1012 is formed inward from the periphery of the through hole 1011, and the flange 1012 is a platform-shaped structure for supporting the water stop piece 102. The flange 1012 is formed with a plurality of fixing holes 1013. In one embodiment, at least one through hole 1014 is provided on the periphery of the ring 101, and the number of the through holes 1014 can adjust the overall specific gravity of the water stop valve piece 10. The water stop piece 102 is made of soft material, and a recess 1021 is formed inward from the outer periphery of the water stop piece 102. The recess 1021 is provided with a plurality of fixing columns 1022 corresponding to the fixing holes 1013. The ring 101 and the water stop piece 102 are integrally formed by injection molding technology, so that the ring 101 and the water stop piece 102 are mutually embedded through the fixing columns 1022 passing through the fixing holes 1013 to form an integral body. In one embodiment, the specific gravity of the hard material and the soft material is less than 1, and further, the hard material is polypropylene, and the soft material is one of silicone or thermoplastic rubber (TPR). The completed structure of the water stop valve piece 10 is shown in Figure 2 .

[0038] Referring to Figure 3 , since the flange 1012 of the ring 101 is formed with the fixing holes 1013, and the ring 101 is a separate component made by injection molding in advance, when the water stop piece 102 is injection molded in the same mold, the periphery of the water stop piece 102 covers the flange 1012 of the ring 101 and fills the fixing holes 1013. After the periphery of the water stop piece 102 covers the flange 1012, the recess 1021 is formed, and the part of the recess 1021 filled with the fixing holes 1013 forms the fixing columns 1022. When the ring 101 and the water stop piece 102 are respectively completed by injection molding, the ring 101 and the water stop piece 102 are integrally formed. Figure 3The fixing columns 1022 of the water stop sheet 102 are tightly fixed through the fixing holes 1013 of the ring 101, so that the ring 101 and the water stop sheet 102 are fixed together and cannot be separated by external force. In an embodiment, the distance between the fixing holes 1013 is the same as the distance between the fixing columns 1022, so that the ring 101 and the water stop sheet 102 are more stably and uniformly fixed.

[0039] Referring to Figure 3 In an embodiment, the water stop sheet 102 has a circular membrane 1023 in the center, and a first ring 1024 is formed around the outside of the membrane 1023. The first ring 1024 is continuously formed around the membrane 1023, and a connecting section 1025 is formed outwardly along the side of the first ring 1024. A second ring 1026 is formed outwardly along the connecting section 1025, and the connecting section 1025 connects the first ring 1024 and the second ring 1026. The second ring 1026 has the groove 1021.

[0040] Referring to Figure 4 With Figure 5 In an embodiment, the thickness of the membrane 1023 is greater than the thickness of the connecting section 1025. When the ring 101 is integrally formed by injection molding, and the temperature of the ring 101 decreases, the ring 101 is connected to the second ring 1026 of the water stop sheet 102, and the connecting section 1025 is pushed inwardly toward the membrane 1023 due to thermal expansion and contraction. Because the thickness of the membrane 1023 is greater than the thickness of the connecting section 1025, the membrane 1023 is less affected by the pushing force F. The pushing force F is further blocked by the first ring 1024. The thickness of the force transmission medium reduces the pushing force F, and the first ring 1024 blocks the pushing force F to maintain the flatness of the surface of the membrane 1023. The flatness of the membrane 1023 is not affected by the pushing force F, and the sealing effect of the cover after infusion is not affected.

[0041] Referring to Figures 6 to 8 For example Figure 6The drip liquid cylinder 20 shown has a liquid inlet 201 at its upper end, and the liquid inlet is connected to a first liquid pipe 202, and the first liquid pipe 202 can be filled with liquid W to be input into the human body, and the bottom of the first liquid pipe 202 has a water outlet 203, which can be connected to a second liquid pipe 204, and the second liquid pipe 204 can be connected to a drip tube to input liquid into the human body. In order to prevent air in the first liquid pipe 202 from entering the body after the liquid W flows out, the first liquid pipe 202 is provided with the water stop valve piece 10 of the utility model inside, the water stop valve piece 10 floats on the liquid surface of the liquid W because its specific gravity is less than 1, and it lowers with the lowering of the liquid surface of the liquid W until the liquid W completely flows into the second liquid pipe 204, and the water stop valve piece 10 is pulled out of the first liquid pipe 202, and the liquid W in the second liquid pipe 204 can continue to flow into the human body. Figure 8 As shown, the diaphragm 1023 of the water stop piece 102 of the water stop valve piece 10 can be attached to the water outlet 203 to prevent air in the first liquid pipe 202 from entering the human body, and because the diaphragm 1023 is made of soft material and is affected by the vacuum suction force in the pipe, the diaphragm 1023 can be better attached to the water outlet 203 to prevent air from entering the human body through the water outlet 203.

[0042] The water stop valve piece of the utility model is provided with an integral forming structure to avoid the situation of part falling off caused by transportation or external force, and the water stop valve piece adopts a combination of two different materials, the water stop piece is made of soft material, and the special structure of the water stop piece can effectively improve the sealing between the water stop valve piece and the water outlet, thereby effectively improving the defects of the current valve piece.

[0043] The above is only the preferred embodiment of the utility model, and does not limit the technical scope of the utility model, so any slight modification, equivalent change and modification of the above embodiment according to the technical essence of the utility model still belongs to the scope of the technical scheme of the utility model.
