Figure 1 As shown, the anti-flatulence bottle plug structure includes a plugging member 1, which includes an inserting portion 10, a transition portion 11 and a blocking portion 12 that are sequentially connected and communicated. The inserting portion 10, the transition portion 11 and the blocking portion 12 are coaxially arranged, that is, the inserting portion 10 and the blocking portion 12 are respectively arranged at both ends of the transition portion 11 to form the overall structure of the plugging member 1, the inserting portion 10, the transition portion 11 and the blocking portion 12 all have ventilation channels, and the ventilation channel of the inserting portion 10 is connected to the ventilation channel of the transition portion 11, and the ventilation channel of the transition portion 11 is connected to the ventilation channel of the blocking portion 12. At the same time, the insertion portion 10 is far from being connected to the transition portion 11. A vent hole 3 is provided at one end of the inserting part 10, so that the end of the inserting part 10 is connected to the outside, and the end of the blocking part 12 away from the transition part 11 is connected to the outside, so as to achieve: the gas in the bottle can flow along the vent channel of the inserting part 10, the vent channel of the transition part 11 and the vent channel of the blocking part 12 in sequence, and flow from the inside of the bottle to the outside. At the same time, the gas outside the bottle can flow along the vent channel of the blocking part 12, the vent channel of the transition part 11 and the vent channel of the inserting part 10 in sequence, and flow from the outside of the bottle to the inside, so that the gas inside and outside the bottle are exchanged, and the gas pressure inside and outside the bottle is balanced.

[0037] The blocking portion 12 is located outside the bottom of the bottle, and the blocking portion 12 contacts the outer side of the bottom of the bottle. The setting of the blocking portion 12 limits the movement of the bottle plug from the outside to the inside of the bottle along the axial direction of the transition portion 11, and the outer diameter of the blocking portion 12 is greater than the maximum outer diameter of the insertion portion 10, so that the blocking portion 12 is restricted outside the bottle. Through the cooperation between the insertion portion 10 and the blocking portion 12, the transition portion 11 is confined to the mounting hole at the bottom of the bottle, and the bottle plug is fixedly installed at the bottom of the bottle.

[0038] When installing the bottle stopper, a force is applied to the insertion portion 10 along the circumferential direction of the bottle stopper, so that the insertion portion 10 is spirally deformed, and the vent hole 3 is squeezed to close the vent hole 3.

[0067] Then, feeding is performed. During feeding, the fastening member 2 is separated from the blocking member 1. Through the baby's swallowing and spitting, the external gas can, under the action of the internal pressure of the feeding bottle, squeeze the vent hole 3 along the ventilation channel of the blocking portion 12, the ventilation channel of the transition portion 11 and the ventilation channel of the insertion portion 10, and enter the inside of the feeding bottle, so that the feeding bottle plug can be ventilated, so that the external gas can enter the feeding bottle through the feeding bottle plug, improve the pressure inside the feeding bottle, balance the air pressure inside and outside the feeding bottle, and prevent flatulence;

[0068] When heating the milk in the bottle, the fastening member 2 is fastened with the blocking member 1 to prevent the milk in the bottle from leaking through the vent hole 3 during the heating process.

[0069] After the bottle stopper has been used for a period of time, it can be replaced with a new one according to actual needs, so that it can be replaced at any time.

[0070] Due to the adoption of the above technical scheme, the anti-flatulence bottle plug structure has a plugging member, and the plugging member has an inserting portion, a transition portion and a blocking portion connected in sequence, and the inserting portion, the transition portion and the blocking portion all have ventilation channels, and the ventilation channels of the inserting portion, the transition portion and the blocking portion are connected in sequence, and the inserting portion is provided with ventilation holes, so that the air outside the bottle flows through the ventilation channels of the blocking portion, the transition portion and the inserting portion, and enters the inside of the bottle through the ventilation holes for ventilation, so as to achieve air pressure balance inside and outside the bottle, prevent the bottle from flatulence, and achieve air circulation in the bottle; the maximum outer diameter of the inserting portion is larger than the outer diameter of the transition portion, so that the inserting portion is aligned with the axis of the bottle plug at the transition portion The outer diameter of the blocking part is larger than the outer diameter of the transition part, so that the blocking part limits the movement of the bottle plug from the outside to the inside of the bottle in the axial direction of the transition part, so that the bottle plug is fixedly inserted in the mounting hole at the bottom of the bottle to prevent the bottle plug from falling off, and the mounting hole at the bottom of the bottle is sealed and ventilated to maintain the air pressure balance inside and outside the bottle; the fastening part is provided, and the fastening part seals the internal space of the sealing part to prevent the milk in the bottle from leaking when the bottle is heated; the sealing part is made of silicone, and will not contaminate the milk when the insertion part contacts the milk, can achieve ventilation, and can be replaced at any time, and is easy to use.

[0071] The above is a detailed description of the embodiments of the utility model, but the contents are only preferred embodiments of the utility model and cannot be considered to limit the scope of implementation of the utility model. All equivalent changes and improvements made within the scope of application of the utility model should still fall within the scope of the patent coverage of the utility model.
