Description

Technical Field

[0001] The utility model relates to the technical field of cup lids, in particular to an anti-spray structure for a straw cup lid. Background Technique

[0002] The cup lid is used to cover the cup mouth of the cup, playing the roles of heat preservation and sealing, preventing external objects from contaminating the water in the cup, and at the same time preventing the water in the cup from overflowing, so that the cup can be carried out.

[0003] In order to drink water more conveniently, the existing cup lids are generally provided with elastic straws and are provided with a two-layer lid. In the normal state, the two-layer lid protects the elastic straw. However, when the cup body is filled with high-pressure beverages, such as cola, etc., at the moment of opening the cup lid, due to the different air pressures inside and outside the cup body, it is very easy for the beverage to spray out through the straw, which is very inconvenient.

[0004] Therefore, we propose an anti-spray structure for a straw cup lid to facilitate solving the problems raised above. Content of the Utility Model

[0005] The purpose of the utility model is to provide an anti-spray structure for a straw cup lid to solve the problems raised in the above background technique.

[0006] To achieve the above purpose, the utility model provides the following technical solution: an anti-spray structure for a straw cup lid, including: a cup lid and a protective lid, the protective lid is rotatably arranged on the cup lid;

[0007] A rib is convexly arranged on the upper surface of the cup lid, and an air hole is vertically penetrated through the cup lid;

[0008] An elastic straw is fixedly installed on the cup lid, and the rib is located between the air hole and the elastic straw;

[0009] An extrusion sealing plate is integrally provided at the middle of the lower surface of the protective lid;

[0010] The extrusion sealing plate cooperates with the extrusion of the elastic straw to block the air hole, and the rib cooperates with the protective lid to extrude the elastic straw.

[0011] Preferably, the elastic straw is clamped in the cup lid.

[0012] Preferably, a locking tongue is integrally provided at the edge of the lower surface of the protective lid, and a delay switch is movably arranged at the edge of the cup lid, and the delay switch is locked with the locking tongue.

[0013] Compared with the prior art, the beneficial effects of the utility model are:

[0014] By setting the rib, the straw remains in a water-sealed state when the delay switch is turned on. Only the protective cover is loose, and the elastic straw moves, exposing the air hole, achieving air pressure balance inside and outside the cup body. Then, when the protective cover is fully opened, the elastic straw leaks out water. Through air pressure balance, the air pressure inside the cup is prevented from being too high, and the water is prevented from spraying out from the elastic straw. Brief Description of the Drawings

[0019] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present utility model.

[0020] Please refer to Figures 1-3 , the present utility model provides a technical solution: an anti-spray structure of a straw cup cover, including: a cup cover 2 and a protective cover 3, and the protective cover 3 is rotatably arranged on the cup cover 2;

[0021] A rib 21 is convexly arranged upward on the upper surface of the cup cover 2, and an air hole 22 is vertically penetrated through the cup cover 2.

[0022] An elastic straw 4 is fixedly installed on the cup cover 2, and the elastic straw 4 is clamped in the cup cover 2, and the rib 21 is located between the air hole 22 and the elastic straw 4;

[0023] An upper locking tongue 32 is integrally provided at the edge of the lower surface of the protective cover 3, and an extrusion sealing plate 31 is integrally provided in the middle of the lower surface of the protective cover 3;

[0024] The extrusion sealing plate 31 cooperates to extrude the elastic straw 4 so that it is blocked at the air hole 22. The rib 21 cooperates with the protective cover 3 to extrude the elastic straw 4 so that the elastic straw 4 is sealed and no water enters or exits. When the protective cover 3 is in a covered state, the elastic straw 4 is sealed, and at the same time the air hole 22 is sealed, forming a closed space inside the cup.

[0025] A delay switch 23 is movably arranged at the edge of the cup lid 2, and the delay switch 23 is locked with the locking tongue 32.

[0026] Working principle: By arranging the rib 21, the straw is still in a water-sealed state when the delay switch 23 is turned on. Only when the protective cover 3 is loose and the elastic straw 4 moves, the air hole 22 is exposed, so as to realize the air pressure balance inside and outside the cup body. Then, when the protective cover 3 is completely opened, the elastic straw 4 leaks out water for drinking. Through the air pressure balance, it is prevented that the air pressure in the cup is too high and the water is sprayed out from the elastic straw 4.

[0027] The content not described in detail in this specification belongs to the prior art well known to those skilled in the art.

[0028] Although the embodiments of the present invention have been shown and described, for those of ordinary skill in the art, it can be understood that various changes, modifications, substitutions and variations can be made to these embodiments without departing from the principle and spirit of the present invention. The scope of the present invention is defined by the appended claims and their equivalents.
