Description

Technical Field

[0001] The utility model relates to the field of drinking water devices, in particular to a bottle mouth ventilation connector and a drinking water device. Background Art

[0002] Drinking bottles such as milk bottles, beverage bottles, sports cups, etc. generally include multiple components, especially milk bottles, which generally include components such as a bottle body, a drinking nipple, a collar for fastening the drinking nipple to the bottle body, and a cover for covering the drinking nipple when the bottle body is not in use. The drinking nipple has an opening for the liquid in the bottle body to come out of the bottle body for consumption by infants or young children. During use, the infant sucks on the drinking nipple to suck out the liquid in the bottle body. As the infant sucks on the drinking nipple and the liquid continuously comes out of the bottle body, a vacuum is gradually formed in the bottle body, and the vacuum makes it difficult for the infant to suck out more liquid from the bottle body and easily causes the infant to swallow air and cause flatulence.

[0003] People have long been aware of the need to avoid babies swallowing air during feeding to prevent adverse reactions such as bloating and vomiting. Some existing feeding bottles have been equipped with a venting device at the mouth of the bottle, which allows the inside of the bottle to communicate with the outside during feeding, thereby balancing the pressure inside and outside the bottle to reduce the amount of air swallowed by the baby.

[0004] However, these milk bottles equipped with the above-mentioned ventilation devices usually contain a certain number of small components. If the ventilation device is fixedly connected to the bottle mouth by a threaded connection or other structure, their assembly and disassembly become more troublesome, and it is time-consuming and laborious to pour liquid into the bottle or remove the ventilation device for cleaning; or the ventilation device is only movably arranged at the bottle mouth, but this method makes the ventilation device unstable, and there is a risk of the ventilation device falling off or its components being lost when the cap is unscrewed to remove the ventilation device.
