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.

Example Embodiment

[0036] Example one

[0037] Please refer to figure 1 with figure 2 , The first embodiment of the present invention is: a one-way valve, made of elastic material, which includes a valve body portion 1 having a hollow structure, the top of the valve body portion 1 is provided with an opening communicating with the hollow structure, the The valve body 1 includes two oppositely arranged connecting walls 2 and two oppositely arranged diaphragms 3. The opposite sides of the connecting wall 2 are respectively connected to the two diaphragms 3, The tops are far away from each other to form the opening, and the bottoms of the two membranes 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 portion 1 or on the side wall of the valve body portion 1.

[0038] In order to ensure the leakage prevention effect of the one-way valve, optionally, abutment planes are respectively provided on the sides of the two membranes 3 close to each other, and the two membranes 3 abut against each other through the abutment planes, In other words, the two sheets of film 3 are in surface contact.

[0039] The elastic material includes but is not limited to silica gel, rubber, soft plastic, etc. In this embodiment, the material of the one-way valve is silica gel with a hardness of 20 duro-100 duro.

[0040] The thickness of the sheet film 3 is smaller than the thickness of the connecting wall 2, such a configuration can ensure that the deformation degree of the sheet film 3 is greater than the deformation degree of the connecting wall 2. The thickness of at least one of the membranes 3 gradually becomes thicker from the bottom to the top. Such a structure allows the bottom of the membrane 3 to be deformed more easily, while taking into account the structural stability of the one-way valve.

[0041] The two diaphragms 3 are arranged in a V shape. It is easy to understand that the two diaphragms 3 may not be V-shaped in some viewing angles, but in the process of rotating/turning the one-way valve However, the two films 3 are V-shaped when viewed from a specific viewing angle. In this case, it should be understood that the two films 3 are arranged in a V shape.

[0042] When viewed from the side, the connecting wall 2 has an upside-down triangle or an upside-down trapezoid shape.

[0043] The one-way valve further includes a fixing portion 4 connected to the top of the valve body portion 1. It is easy to understand that the fixing portion 4 and the valve body portion 1 are an integral structure, in other words In other words, the fixing portion 4 and the valve body portion 1 are integrally injection molded. Specifically, the fixing portion 4 includes a column portion 5, the column portion 5 is provided with a through hole, and the through hole communicates with the hollow structure through the opening. In more detail, a limit part is provided on the outer wall of the column part 5. In this embodiment, the limiting portion includes a limiting ring 6 arranged at intervals, a limiting groove 7 is formed between the two limiting rings 6, and the limiting ring 6 away from the valve body 1 is located The end of the fixing portion 4 and the top surface of the limiting ring 6 have a plurality of convex ribs 8 arranged at intervals, and two adjacent convex ribs 8 are formed to communicate with the limiting ring 6 The groove 9 between the outer wall and the through hole, optionally, the rib 8 is arranged along the radial direction of the column 5.

[0044] In this embodiment, the column 5 is cylindrical. In other embodiments, the column 5 may also be J-shaped, L-shaped, etc. The column 5 with a bending area can avoid the container The inner substance directly impacts the abutting area of the two membranes 3, which is beneficial to further improve the leakage prevention effect.

Example Embodiment

[0045] Example two

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

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

[0048] In this embodiment, the container is a water tank in a dental flusher. In other embodiments, the container may also be a lunch box, a fermentation tank, an infusion bottle, and so on. Due to the existence of the one-way valve, the air pressure inside and outside the container is balanced, which effectively solves the problems of difficulty in extracting liquid from the container and difficulty in opening the container lid.

[0049] In summary, the one-way valve, container and dental flusher provided by the present invention have simple structure, easy processing, low manufacturing cost, small volume, small space occupation, good structural stability and long service life; The pressure difference between the inside and outside of the container is balanced, and the liquid in the container is drawn smoothly.
