The suction pipe drinking cup of existing use can be smoothly with water from the suction pipe suction for guaranteeing, and the product need add one-way admission valve for can be when drinking water in the leading-in cup of outside atmospheric pressure, balanced cup internal gas pressure leads to the drinking cup structure comparatively complicated, has increased the cost of manufacture of drinking cup product.
SUMMERY OF THE UTILITY MODEL
In order to solve the problem, the utility model provides a sealing ring. The utility model discloses a set up the air channel on the supporting ring of drinking cup sealing washer to utilize seal lip and bowl cover bottom to form sealedly, make water in the drinking cup can not leak outward, when drinking water, in outside air can get into the cup through clearance and air channel between cup external screw thread and the bowl cover internal thread, form the one-way effect that switches on, the product need not to add one-way admission valve in addition, effectively simplifies the product structure, reduces product cost.
In order to achieve the above purpose, the utility model is implemented according to the following technical scheme:
the sealing ring comprises a supporting ring and a sealing lip, the bottom of the supporting ring is provided with a flexible sealing lip extending towards the inner side of the supporting ring, and the top of the supporting ring is provided with at least one vent groove communicated with the inner side and the outer side of the supporting ring.
Preferably, the sealing lip is tilted upwards.
Preferably, the vent grooves are uniformly arranged at intervals along the circumferential direction of the supporting ring.
Preferably, the sealing ring is a silica gel sealing ring, and the hardness of the sealing lip is 30-70A.
Preferably, the bottom surface of the supporting ring is provided with a taking piece.
The utility model has the advantages that:
the utility model discloses a set up the air channel on the supporting ring of drinking cup sealing washer to utilize seal lip and bowl cover bottom to form sealedly, make water in the drinking cup can not leak outward, when drinking water, in outside air can get into the cup through clearance and air channel between cup external screw thread and the bowl cover internal thread, form the one-way effect that switches on, the product need not to add one-way admission valve in addition, effectively simplifies the product structure, reduces product cost.

fig. 2 is a schematic cross-sectional view of the present invention;
FIG. 3 is a sectional view of the utility model in use;
in the figure 1-3, 1-supporting ring, 2-sealing lip, 3-vent groove, 4-taking sheet, 5-cup body and 6-cup cover.
Detailed Description
In order to make the objects, technical solutions and advantages of the present invention clearer, the following will explain in detail a preferred embodiment of the present invention with reference to the accompanying drawings to facilitate understanding of the skilled person.
As shown in fig. 1-3, the sealing ring comprises a supporting ring 1 and a sealing lip 2, the bottom of the supporting ring 1 is provided with the flexible sealing lip 2 extending towards the inner side of the supporting ring, the top of the supporting ring 1 is provided with at least one vent groove 3 communicating the inner side and the outer side of the supporting ring 1, the shape of the supporting ring 1 can be produced according to the shape of the cup body 5, the sealing lip 2 and the supporting ring 1 are integrally formed, a gap at a joint is avoided, and good sealing performance cannot be ensured; when drinking water, the water in the cup 5 is directly sucked out by the suction pipe, a negative pressure is formed in the cup 5, and the outside air enters the cup 5 through the gap between the cup 5 and the cup cover 6 and the vent groove 3, so that a one-way conduction effect is formed, an air inlet valve is not required to be additionally arranged on the cup cover 6, the use is more convenient, the structure of the cup cover 6 is simplified, and the manufacturing cost of the water cup is reduced.
Preferably, the sealing lip 2 is tilted upwards, so that the elasticity of the sealing lip 2 is improved, the sealing lip 2 is contacted with the cup cover 6 more tightly, and the sealing effect of the sealing lip 2 is ensured.
Preferably, the vent grooves 3 are uniformly arranged along the circumferential direction of the support ring 1 at intervals, and a plurality of air inlet channels are arranged to ensure that air can be more smoothly introduced.
Preferably, the bottom surface of the supporting ring 1 is provided with the taking piece 4, so that the sealing ring can be conveniently taken down from the cup cover 6, and the use is more convenient.
Preferably, the sealing ring is a silica gel sealing ring, the hardness of the sealing lip 2 is 30-70A, and the fact that the sealing lip 2 can be effectively driven to deform by external air introduced from the vent groove 3 is guaranteed, so that air can smoothly enter the cup body, and meanwhile the sealing lip 2 can form effective sealing with the cup cover 6 when air does not enter the cup body.
The utility model discloses a set up the air channel on the supporting ring of drinking cup sealing washer to utilize seal lip and bowl cover bottom to form sealedly, make water in the drinking cup can not leak outward, when drinking water, in outside air can get into the cup through clearance and air channel between cup external screw thread and the bowl cover internal thread, form the one-way effect that switches on, the product need not to add one-way admission valve in addition, effectively simplifies the product structure, reduces product cost.
Finally, it is noted that the above preferred embodiments illustrate rather than limit the invention, and that, although the invention has been described in detail with reference to the above preferred embodiments, it will be understood by those skilled in the art that various changes in form and details may be made therein without departing from the scope of the invention as defined by the appended claims; the size of the attached figure is irrelevant to the specific real object, and the size of the real object can be changed at will.
