The structure/working principle of the invention is briefly described as follows: after the one-way valve is installed on a container, the two film sheets 3 with the bottoms abutting against each other break a connecting channel between a hollow structure of the one-way valve and an inner cavity of the container, so that the leakage of substances in the container through the one-way valve is avoided, and the leakage-proof function of the one-way valve is further exerted; when the air pressure in the container is lower than the external atmospheric pressure, the external atmospheric pressure can prop open the two film sheets 3, so that the bottoms of the two film sheets 3 are away from each other, and a connecting channel between the hollow structure of the one-way valve and the inner cavity of the container is opened to balance the air pressure difference between the inside and the outside of the container, thereby playing the ventilation role of the one-way valve.

From the above description, the beneficial effects of the present invention are: the one-way valve has the advantages of simple structure, easy processing, low manufacturing cost, small volume, small occupied space, good structural stability and long service life.

Further, the thickness of the sheet film 3 is smaller than that of the connecting wall 2.

As can be seen from the above description, the structural strength of the connecting wall 2 is greater than that of the sheet membrane 3, so that the sheet membrane 3 is more easily deformed, and the opening and closing sensitivity of the check valve is improved.

Further, the thickness of at least one of the sheet films 3 becomes gradually thicker from the bottom thereof to the top thereof.

As is apparent from the above description, the thickness of the sheet film 3 becomes gradually thicker from the bottom portion thereof to the top portion thereof, while taking into account the structural strength of the sheet film 3 and the deformability of the sheet film 3. It will be readily appreciated that the one-way valve provided by the present invention is essentially a one-piece membrane 3 one-way valve, as the thickness of one piece of membrane 3 is maintained to be the same as the thickness of the connecting wall 2.

Further, two of the sheet films 3 are arranged in a V-shape.

Further, the valve body part comprises a fixing part 4, and the fixing part 4 is connected to the top of the valve body part 1.

As will be understood from the above description, the check valve is fixed to the container by the fixing portion 4.

Further, the fixing portion 4 includes a column portion 5, a through hole is provided on the column portion 5, and the through hole is communicated with the hollow structure through the opening.

As can be seen from the above description, the shape of the pillar portion 5 and the relative position of the pillar portion 5 and the valve body portion 1 can make the check valve present different types as a whole to adapt to different application scenarios, such as I-type, L-type, and J-type.

Furthermore, a limiting part is arranged on the outer wall of the column part 5.

As can be seen from the above description, the check valve is fixed on the container by the limit part.

Further, the limiting part comprises limiting rings 6 arranged at intervals, a limiting groove 7 is formed between the limiting rings 6, the limiting rings 6 far away from the valve body part 1 are located at the end parts of the fixing parts 4, the top surfaces of the limiting rings 6 are provided with a plurality of convex ribs 8 arranged at intervals, and adjacent two convex ribs 8 are communicated with the outer wall of the limiting ring 6 and a groove 9 of the through hole.

From the above description, it can be known that the design of the groove 9 can increase the ventilation amount of the check valve, and simultaneously, the situation that the check valve is blocked by interference can be avoided.

A container comprising the one-way valve described above.

The tooth flushing device comprises the container.
