Abstract
The invention discloses an one-way valve, a container and a water pick. The one-way valve is made of an elastic material and comprises a valve body part with a hollow structure, an opening communicating with the hollow structure is formed in the top of the valve body part, the valve body part comprises two oppositely-arranged connecting walls and two oppositely-arranged membranes, the two membranes are connected with the two opposite sides of each connecting wall correspondingly, the tops of the two membranes are far away from each other, and the bottoms of the two membranes abut against eachother. After the one-way valve is installed on the container, the two membranes with the bottoms abutting against each other break a connecting channel between the hollow structure of the one-way valve and the inner cavity of the container, and then the leakage-proof effect is achieved; and when the air pressure in the container is smaller than the external atmospheric pressure, the external atmospheric pressure can prop open the two membranes, so that the bottoms of the two membranes are away from each other to open the connecting channel between the hollow structure of the one-way valve andthe inner cavity of the container, and the ventilation effect is achieved. The one-way valve is simple in structure, easy to machine, low in manufacturing cost, small in size, small in occupied space,good in structural stability and long in service life.
