Description

Technical Field

[0001] The utility model relates to the technical field of water-soluble paper trigger valves, in particular to an automatic trigger valve which is convenient for replacing water-soluble paper. Background Art

[0002] A car-mounted lifebuoy refers to a type of water life-saving equipment, which is usually placed on the car. Before falling into the water, the lifebuoy is in a contracted state. After falling into the water, the water-soluble paper at the mouth of the inflation bottle dissolves when it comes into contact with water. The inflation bottle is opened to automatically inflate the lifebuoy, making it expand, so that the person who falls into the water can quickly save himself.

[0003] The water-soluble paper in the trigger valve is disposable and will dissolve when exposed to water. At present, some places the water-soluble paper in the trigger valve. Since the trigger valve is small and the water-soluble paper is hidden inside the trigger, it is difficult to replace it after it dissolves, which makes the trigger valve unusable. Some places the trigger valve on the mouth of the inflation bottle. However, after the water-soluble paper melts, if the water-soluble paper is only glued to the mouth of the bottle, it will easily fall off and the sealing is poor. Moreover, the current inflation device is only equipped with an air needle, which can only inflate one lifebuoy at a time, and cannot inflate multiple lifebuoys at the same time.
