[0020] The present invention will be described in further detail below with reference to the accompanying drawings.
[0021] Identical components are denoted by the same reference numerals. It should be noted that the terms "front," "rear," "left," "right," "upper," and "lower" used in the following description refer to directions in the accompanying drawings, and the terms "bottom," "top," "inner," and "outer" refer to directions toward or away from the geometric center of a particular component, respectively.
[0022] As shown in the figure, a water cup with good sealing performance includes a cup body 1 and a screw-on lid 2. A flip cover 3 is hingedly connected to the screw-on lid 2. A water outlet 4 is formed at the top of the screw-on lid 2. A guide post 5 is provided on the lower surface of the flip cover 3. The guide post 5 has a guide groove extending through its bottom end. A seal 6 is provided on the guide post 5. The seal 6 includes a connecting sleeve 601 that is sleeved and slidably connected to the guide rod. A guide rod 602 is provided in the connecting sleeve 601 and slidably connected to the guide groove. A spring 7 is provided in the guide groove. The ends of the spring 7 are fixedly connected to the inner wall of the end of the guide groove and the end of the guide rod 602. When the flip cover 3 is in the closed state, the seal 6 seals the water outlet 4. The cup also includes a positioning assembly for positioning the flip cover 3 and the screw-on lid 2. The positioning assembly is a prior art and will not be described in detail in this embodiment.
[0023] When the flip cover 3 is rotated toward the rotary cover 2 so that the sealing member 6 comes into contact with the rotary cover 2, the guide sleeve slides along the guide post 5, so that the spring 7 is compressed. When the flip cover 3 is completely closed, the elastic force of the spring 7 enables the sealing member 6 to completely cover the water outlet 4 and press against the surface of the rotary cover 2 to improve the sealing effect.
[0024] The surface of the flip cover 3 is provided with an exhaust hole 8 penetrating the guide groove. When the flip cover 3 is closed, the air inside the connecting sleeve 601 can be discharged from the exhaust hole 8 when the connecting sleeve 601 slides relative to the guide post 5, ensuring that the flip cover 3 is closed smoothly.
[0025] A contact portion 603 is provided at the bottom end of the connecting sleeve 601. The diameter of the contact portion 603 is larger than the diameter of the water outlet 4. When the flip cover 3 is in the closed state, the contact portion 603 contacts the surface of the rotary cover 2 and covers the water outlet 4. When the flip cover 3 is in the closed state, under the action of the elastic force of the spring 7, the contact portion 603 is pressed tightly against the surface of the rotary cover 2 and completely covers the water outlet 4, thereby improving its sealing effect.
[0026] The lower surface of the abutment portion 603 is provided with an insertion portion 604 inserted into the water outlet 4, and the side wall of the insertion portion 604 is provided with a sealing ring 605. The top of the water outlet 4 is arc-shaped. When the flip cover 3 is closed, the insertion portion 604 is inserted into the water outlet 4, and the peripheral side of the sealing ring 605 abuts against the inner wall of the water outlet 4 and gradually deforms, thereby further improving the sealing effect of the water outlet 4.
[0027] A convection port 9 is formed on the surface of the screw cap 2 on one side of the water outlet 4. A connecting block 606 is provided on one side of the connecting sleeve 601. A sealing rod 607 is provided at the bottom of the connecting block 606 to seal the convection port 9. A water retaining edge 10 is provided on the surface of the screw cap 2 around the water outlet 4. The height of the water retaining edge 10 gradually decreases at both ends. The water outlet 4 is closer to the side with the higher height of the water retaining edge 10, and the convection port 9 is located on the side away from the higher height of the water retaining edge 10.
[0028] When the water in the cup body 1 is discharged from the water outlet 4, the water flows out from the higher end of the water retaining edge 10. By setting the convection port 9, the external air can enter the cup body 1 through the convection port 9, thereby ensuring that the water in the cup body 1 can be poured out smoothly, and the convection port 9 is sealed by the sealing rod.
