Description

Cup cover capable of drinking water smoothly

Technical Field

The utility model relates to a cup cover of a drinking cup, in particular to a cup cover with smooth drinking water.

Background

The common drinking cup is to make water out smooth, often set up the inlet port on the bowl cover in order to balance the inside and outside atmospheric pressure of cup, be provided with the sealing plug on the inlet port for keeping clean.

Some people who seek to drink water quickly, such as people who have just moved, tend to align the water drinking port with the mouth, then tilt or invert the water cup for drinking, at this time, the water surface in the cup body is over the air inlet hole, so that water flows out of the air inlet hole, and meanwhile, air cannot enter the cup body from the air inlet hole, so that the pressure in the cup body is reduced, and the speed of water flowing out of the cup body is reduced. As water flows out of the cup body, the pressure in the cup body is further reduced, and air enters the cup body from the drinking hole; on the one hand, the drinking water port is used for discharging water, on the other hand, air is introduced, so that the water can not flow smoothly, and the water can enter the air pipe to cause choking.

Disclosure of Invention

Aiming at the problems existing in the prior art, the utility model provides a cover with smooth drinking water.

The technical scheme adopted for solving the technical problems is as follows: the cup cover is used for being connected with a cup body to form a sealed water storage space, and comprises a main body and a water drinking port penetrating through the main body and protruding upwards, wherein an upper cover is arranged on the water drinking port and is in threaded connection with the water drinking port; the device also comprises a vent hole and a one-way ventilation water retaining component which are arranged on the main body; the unidirectional ventilation water retaining assembly comprises a support frame and a unidirectional plug which are arranged in the ventilation hole, wherein the support frame is provided with a mounting hole for mounting the unidirectional plug and an air channel for air to pass through; the one-way plug comprises a limiting part for preventing the one-way plug from moving into the cup body, a columnar connecting part matched with the mounting hole and an elastic blocking piece for covering the air channel; one surface of the elastic blocking piece far away from the cup body is contacted with the supporting frame.

As shown in fig. 1-22, is a specific embodiment of the present utility model: the cup cover is used for being connected with a cup body to form a sealed water storage space, and comprises a main body 1 and a water drinking port 11 penetrating through the main body 1 and protruding upwards, wherein an upper cover 12 is arranged on the water drinking port 11, and the upper cover 12 is in threaded connection with the water drinking port 11; the device also comprises a vent hole 4 and a one-way ventilation water retaining component 5 which are arranged on the main body 1; the one-way ventilation water-retaining assembly 5 comprises a supporting frame 51 and a one-way plug 52 which are installed in the ventilation hole 4, wherein the supporting frame 51 is provided with an installation hole 511 for installing the one-way plug 52 and an air channel 512 for air to pass through; the one-way stopper 52 includes a stopper 521 which prevents the one-way stopper 52 from moving into the cup body, a columnar connection 522 which is fitted with the mounting hole 511, and an elastic blocking piece 523 which covers the air passage 512; the side of the elastic blocking piece 523 away from the cup body is contacted with the supporting frame. When the drinking water cup is tilted or the drinking water port 11 is used for drinking water upside down, the elastic blocking piece 523 is covered by water, the pressure in the cup body is gradually reduced while the water is drunk, when the pressure in the cup body for the elastic blocking piece 523 is lower than the external atmospheric pressure, the unidirectional plug 52 is subjected to pressure towards the inside of the cup body, the unidirectional plug 52 is prevented from moving towards the inside of the cup body by the limiting part 521, the elastic blocking piece 523 is deformed under the action of the pressure, as the elastic blocking piece 523 has enough deformation space towards one side of the cup body, the elastic blocking piece 523 can not completely cover the air channel 512, the air outside the cup body enters the cup body through the air channel 512 until the pressure acting on the elastic blocking piece 523 is reduced or disappears, the internal and external air pressures of the cup body tend to be balanced, and the elastic blocking piece 523 is restored to the original state. The water flows out from the water drinking port 11, and the air enters the cup body from the vent hole 4, so that the influence of the air on the cup body is avoided, and the turbulence is not easy to generate; the internal and external pressure of the cup body tend to be balanced, and water flows out smoothly. When the atmospheric pressure in the cup body and the atmospheric pressure outside are equal, the water covers the elastic blocking piece 523, the pressure acts on the elastic blocking piece 523 to generate pressure deviating from the inside of the cup body to the unidirectional plug 52, and the elastic blocking piece 523 deforms under the action of the pressure, but because the surface, far away from the cup body, of the elastic blocking piece 523 is in contact with the supporting frame, namely the elastic blocking piece 523 is clung to the air channel 512 more, and the water cannot flow out of the cup body through the ventilation holes 4. The supporting frame 51 may have a mesh structure or a porous structure with the mounting hole 511 in the middle; the mounting hole 511 is matched with the columnar connection part 522, and the columnar connection part 522 can be a cylinder or a prism; the limiting portion 521 may be a cylinder or a sphere having a diameter larger than the inner diameter of the mounting hole 511.

When the water drinking port 11 is used for drinking water, the cup body is inclined, and water covers the elastic blocking piece 523, pressure acts on the elastic blocking piece 523 to generate pressure deviating from the inside of the cup body on the unidirectional plug 52, and the elastic blocking piece 523 deforms under the action of the pressure, but as one surface of the elastic blocking piece 523 far away from the cup body is in contact with the supporting frame, namely, one side of the elastic blocking piece 523 facing the cup body does not have enough deformation space, and gaps are not generated between the edge of the elastic blocking piece 523 and the inner surface of the vent hole 4; the deformation of the elastic blocking piece 523 can make the edge of the elastic blocking piece 523 tightly contact with the inner surface of the ventilation hole 4, so that water cannot flow out of the cup body through the ventilation hole 4. When the elastic blocking piece 523 is covered by water in the cup body, the elastic blocking piece 523 with arc-shaped protrusions gives greater pressure to the inner surface of the vent hole 4 when being deformed, and the edge of the elastic blocking piece 523 is in closer contact with the inner surface of the vent hole 4.
