Detailed Description

The technical solution of the present embodiment is further described below by way of specific embodiments with reference to the accompanying drawings.

As shown in fig. 1-20, is a specific embodiment of the present utility model: the cup cover of the flip cover 12 is used for being connected with a cup body to form a sealed water storage space, and comprises a main body 1, a straw assembly 2 and a straight drinking port 11 penetrating through the main body 1 and protruding upwards, the straight drinking port 11 is provided with the flip cover 12, the rear end of the flip cover 12 is rotatably arranged on the main body 1, an elastic ring used for enabling the flip cover 12 to be automatically opened is arranged between the flip cover 12 and the main body 1, and the front end of the flip cover 12 is connected with or separated from the main body 1 through a switch assembly 3; and the cup also comprises a vent hole 4 arranged on the main body 1 and a one-way ventilation water blocking assembly 5 which allows air to enter the cup body through the vent hole 4 and prevents water from flowing out of the cup body through the vent hole 4. After the hot water is added into the cup body for a period of time, the temperature of the water is reduced, the volume is reduced, the pressure in the cup body is seriously lower than the external atmospheric pressure, but because of the existence of the unidirectional ventilation water retaining component 5, air can automatically enter the cup body through the ventilation hole 4, and the pressure inside and outside the cup body is balanced, so that the force required for opening the flip 12 is the same as that in ordinary times; when the straw assembly 2 of the utility model is used for absorbing water and drinking, the air pressure inside and outside the cup body is balanced by automatically entering the cup body through the vent holes 4, so that the liquid in the cup body can smoothly flow out.

The one-way ventilation water blocking assembly 5 comprises a support frame 51 and a one-way plug 52 which are installed in the ventilation hole 4, and an installation hole 511 for installing the one-way plug 52 is formed in the support frame 51; the unidirectional plug 52 comprises a limit part 521 for preventing the unidirectional plug 52 from moving into the cup body, a columnar connecting part 522 matched with the mounting hole 511 and an elastic blocking piece 523 with the edge contacted with the inner surface of the vent hole 4; the side of the elastic blocking piece 523 away from the cup body is in contact with the mounting frame. When the pressure in the cup body is lower than the external atmospheric pressure, the edge of the elastic blocking piece 523 of the unidirectional plug 52 is in contact with the inner surface of the ventilation hole 4, the pressure acts on the elastic blocking piece 523, the unidirectional plug 52 is pressed towards the inside of the cup body, the limiting part 521 prevents the unidirectional plug 52 from moving towards the inside of the cup body, the elastic blocking piece 523 deforms under the action of the pressure, as the edge of the elastic blocking piece 523 towards one side of the cup body has enough deformation space, the deformation of the elastic blocking piece 523 enables the edge of the elastic blocking piece 523 to form a gap with the inner surface of the ventilation hole 4, and the air outside the cup body enters the cup body 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 edge of the elastic blocking piece 523 is in contact with the inner surface of the ventilation hole 4 again. When the drinking water is drunk through the drinking port 11, the cup body is inclined, pressure acts on the elastic blocking piece 523 when the water covers the elastic blocking piece 523, pressure deviating from the inside of the cup body is generated 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 contacted with the mounting 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 contact with the inner surface of the ventilation hole 4 more tightly, so that water cannot flow out of the cup body through the ventilation hole 4. The supporting frame 51 may have a mesh structure in which the mounting hole 511 is located 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.

The elastic blocking piece 523 protrudes in an arc shape toward the cup body. When the elastic blocking piece 523 is covered by water in the cup body, the arc-shaped protrusions give 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.

The suction pipe assembly 2 comprises a first water suction channel 21 communicated with the inner part of the cup body and a suction pipe head 23 provided with a second water suction channel 22; the main body 1 is provided with a yielding groove 13 for accommodating the straw head 23, the straw head 23 is rotationally arranged in the yielding groove 13, and the first water absorption channel 21 is arranged at the bottom of the yielding groove 13; with rotation of the pipette head 23; the first water sucking channel 21 and the second water sucking channel 22 are staggered to form a seal of the suction pipe assembly 2 or the first water sucking channel 21 and the second water sucking channel 22 are aligned to form communication of the suction pipe assembly 2. The suction tube assembly 2 realizes the sealing and the conduction of the first suction channel 21 through the suction tube head 23, and has a compact structure. In practical use, a suction pipe is additionally arranged below the first water suction channel 21, one end of the suction pipe is connected with the first water suction channel 21 after being additionally arranged, and the other end of the suction pipe extends into the cup body to be close to the bottom of the cup body.

The middle part of the suction pipe head 23 is rotatably provided with a cover plate 231. The cover plate 231 covers the suction pipe head 23, so that the suction pipe head 23 is kept clean and sanitary.
