Description

Technical Field

[0001] The utility model relates to the technical field of cup covers, and more particularly to a drinking water cup cover. Background Art

[0002] At present, the cup lid is a device used to close the opening of the container. It prevents the liquid from flowing out by fitting tightly to the opening of the container, thereby achieving the sealing function of the container. In order to improve the convenience of drinking, a straw is combined with the cup lid. The presence of the straw greatly simplifies the process of drinking water. In order to prevent the straw from being contaminated by the environment, the cup lid is often provided with a movable cover to protect it.

[0003] However, there are still some defects in the above-mentioned existing technologies. In order to facilitate drinking water, the existing cup lid is provided with a vent hole for balancing air pressure, and a sealing gasket is provided on the movable lid. The sealing gasket cooperates with the vent hole when not drinking water, so as to reduce the pollution in the container. However, when drinking water, the movable lid is opened to drink water, and the sealing gasket will be exposed to the external environment and easily contaminated. In addition, the sealing gasket provided on the movable lid is easy to fall off by contact and detent. The gasket is a small part and there is a risk of accidental ingestion by children when using it. Utility Model Content

[0022] The present invention will be described in further detail below with reference to the accompanying drawings.

[0023] This embodiment discloses a drinking cup cover, such as Figures 1 to 6 As shown, the cup lid body 1 includes an arc-shaped cavity 11, which is provided with a drinking hole 111 and an air vent 112. The drinking hole 111 is used for drinking water, and the air vent is used to connect to the outside atmosphere and balance the internal air pressure. The arc-shaped cavity 11 is provided with a rotatable rotating spout 2, which is provided with a water absorption hole 21 and an air vent groove 22 that match the drinking hole 111 and the air vent 112 respectively. The rotating spout 2 has two states: open and closed. In the open state, the water absorption hole 21 and the air vent groove 22 are connected to the drinking hole 111 and the air vent 112 respectively. In the closed state, the water absorption hole 21 and the air vent groove 22 are offset from the drinking hole 111 and the air vent 112 respectively. In both the open and closed states, the water absorption hole 21 and the air vent groove 22 are located within the arc-shaped cavity 11, with less contact with the external environment, reducing the possibility of contamination.

[0024] As a further improvement, a gap 3 is left between the rotating spout 2 and the side wall of the arc-shaped cavity 11, and the ventilation groove 22 connects the rotating surface of the rotating spout 2 and the gap 3. When the utility model is in the open state, the ventilation groove 22 is connected to the ventilation port 112, allowing external air to enter the ventilation groove 22 through the gap 3, and the internal air pressure of the utility model is balanced through the ventilation port 112, making it easy to open the utility model for drinking water.

[0025] As a further improvement, a corresponding sealing gasket 4 is provided between the rotating spout 2 and the arc-shaped cavity 11. The sealing gasket is provided with corresponding holes A41 and holes B42 corresponding to the ventilation groove 22 and the ventilation port 112. The sealing gasket 4 is made of a flexible material and is always in contact with the rotating surface of the rotating spout 2. The rotating spout 2 will press the sealing gasket 4, and under the pressure of the rotating spout 2, the sealing gasket 4 will press against the upper surface of the arc-shaped cavity 11, so that in the closed state, the sealing gasket 4 forms a continuous sealing barrier through contact to prevent leakage. The arrangement of the holes A41 and B42 ensures that when the sealing gasket 4 is open, it will not affect the conduction between the water intake hole 21 and the drinking hole 111, or between the ventilation groove 22 and the ventilation port 112.

[0026] Furthermore, the sealing gasket 4 is made of food-grade silicone. This silicone is a material that can come into direct contact with food and has excellent thermal and chemical stability. It will not ingest harmful ingredients due to the material, thus meeting strict food safety standards.

[0027] Further improvement, the water suction hole 21 includes a water inlet 211 and a water outlet 212, and the inner diameter of the water inlet 211 is smaller than the inner diameter of the water outlet 212. Some users may choke when drinking water due to excessive suction. By setting the water suction hole 21 with an inner diameter of the water inlet 211 smaller than the inner diameter of the water outlet 212, the liquid flow rate inside the water suction hole 21 is limited, so that the liquid flow rate is moderate when drinking water, which can prevent choking due to excessive suction.

[0028] Further improvement, the rotating spout 2 is symmetrically provided with a rotating shaft protrusion 24, the arc-shaped cavity 11 is provided with a bucket-shaped groove 113, and the bucket-shaped groove 113 is provided with a rotating seat 114 adapted to the rotating shaft protrusion 24. The rotating shaft protrusion 24 can be installed on the adapted rotating seat 114 through the bucket-shaped groove 113, so that the rotating shaft protrusion 24 can be easily and conveniently installed and disassembled on the rotating seat 114. The minimum diameter of the bucket-shaped groove 113 is smaller than the diameter of the rotating shaft protrusion 24. The minimum inner diameter of the bucket-shaped groove 113 will hinder the rotating shaft protrusion 24, making it difficult for the installed rotating shaft protrusion 24 to fall out.

[0029] Further improvement, the cup cover body 1 is provided with a placement cavity 12 adapted for the rotating spout 2, and the rotating spout 2 is in the placement cavity 12 in the closed state. The rotating spout 2 enters the placement cavity 12 when in the closed state, so that the present invention can reduce contact with the external environment when not in use, reducing the possibility of contamination.

[0030] For further improvement, the rotating spout 2 is provided with a prying protrusion 23 with a friction protrusion 231. The setting of the prying protrusion 23 can provide an additional force point for the rotation of the rotating spout 2, so that the rotating kettle can be easily switched between the open and closed states. The setting of the friction protrusion 231 makes it difficult for the prying protrusion 23 to slip when pushed.

[0031] Working principle of the utility model

[0032] When drinking water, push and bend the protrusion 23, and the rotating spout 2 can be simply pushed up to enter the open state. The drinking port is connected to the water suction hole 21 for drinking water, and the air vent 112 is connected to the air vent groove 22 for balancing the air pressure. Water can be drunk by rotating the spout 2. The inner diameter of the water inlet 211 is smaller than the inner diameter of the water outlet 212, so that the liquid flow rate inside the water suction hole 21 is limited to avoid choking due to excessive suction.

[0033] When storing, push the rotating spout 2 into the placement cavity 12 to enter the closed state, and the water absorption hole 21 and the air vent 22 are respectively offset from the drinking hole 111 and the air vent 112. The rotating spout 2 will press the sealing gasket 4 to realize the sealing function of the container. In the open and closed states, the water absorption hole 21 and the air vent 22 are both in the arc cavity 11, with less contact with the external environment, reducing the possibility of contamination.

[0034] The rotating spout 2 can be easily assembled and disassembled through the bucket-shaped groove 113, so that the sealing gasket 4 can also be easily and conveniently replaced.

[0035] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent replacements, improvements, etc. made within the design concept of the present invention should be included in the scope of protection of the present invention.
