Problems solved by technology

In the prior art, most of the waterproof and breathable membranes are used to realize the ventilation and leakage prevention of the closed container. Although the waterproof and breathable membrane can realize the liquid leakage prevention, its ventilation effect is not good. There is a high chance of damage

Embodiment 1

[0037] Please refer to figure 1 and figure 2 , Embodiment 1 of the present invention is: a one-way valve, made of elastic material, which includes a valve body part 1 with a hollow structure, the top of the valve body part 1 is provided with an opening communicating with the hollow structure, the The valve body part 1 includes two oppositely arranged connecting walls 2 and two oppositely arranged membranes 3, the opposite sides of the connecting walls 2 are respectively connected with two said membranes 3, and the two membranes 3 are connected to each other. The tops are separated from each other to form the opening, and the bottoms of the two sheets 3 abut against each other to close the bottom end of the hollow structure. It is easy to understand that the opening can be provided on the top end surface of the valve body part 1 or on the side wall of the valve body part 1 .

[0038] In order to ensure the leak-proof effect of the one-way valve, optionally, abutting planes a...

Embodiment 2

[0046] Please refer to Figure 1 to Figure 7 , Embodiment 2 of the present invention is a container structure proposed on the basis of Embodiment 1, specifically: a container, including a body 10 and a one-way valve arranged on the body 10, the one-way valve It is the one-way valve described in Embodiment 1.

[0047]The body 10 is provided with an air port 11 and at least one liquid inlet and outlet 12, the air port 11 is provided with a snap ring 13, and the one-way valve is engaged with the limiting groove 7 through the snap ring 13 On the container, the gas port 11 is arranged on the top of the container, and the top surface of the container is also provided with a vent groove 14 communicating with the gas port 11, and the vent groove 14 communicates with the outer wall of the container. Preferably, the top surface of the one-way valve is set lower than the bottom surface of the ventilation groove 14 .

[0048] In this embodiment, the container is a water tank in a dental...

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.

Description

technical field [0001] The invention relates to the technical field of one-way valves, in particular to a one-way valve, a container and a dental flosser. Background technique [0002] Some containers need to be equipped with a one-way valve structure (such as the water tank of the dental flosser, etc.) to balance the air pressure difference inside and outside the container and prevent the substances contained in the container (such as liquid, etc.) from flowing out. In the prior art, most of the waterproof and breathable membranes are used to realize the ventilation and leakage prevention of the closed container. Although the waterproof and breathable membrane can realize the liquid leakage prevention, its ventilation effect is not good. There is a high chance of damage. Contents of the invention [0003] The technical problem to be solved by the present invention is to provide a breathable and leak-proof one-way valve, a container with the one-way valve and a dental flo...
