It should be understood that the data used in this way can be interchangeable under appropriate circumstances, so that the embodiments of the present application can be implemented in an order other than those illustrated or described here, and the objects distinguished by "first", "second", etc. are generally of one type, and the number of objects is not limited. For example, the first object can be one or more. In addition, "and / or" in the specification and claims represents at least one of the connected objects, and the character " / " generally indicates that the objects associated with each other are in an "or" relationship.

[0032] The bottle stopper sealing structure provided in the embodiment of the present application is described in detail below through specific embodiments and their application scenarios in combination with the accompanying drawings.

[0033] like Figures 1 to 5As shown, an embodiment of the present application provides a bottle stopper sealing structure, including a shell member 100 for connecting to a cup body, a through cavity 130 penetrating the shell member 100, and a mounting base 600 fixedly connected to the shell member 100 and located in the through cavity 130, and a button 200, a valve member 300, and a cover plate 400 coaxial with the shell member 100 and coupled to each other are elastically slidable along the axial direction of the shell member 100 on the mounting base 600.

[0034] The button 200 and the cover plate 400 are located at one end of the outer shell 100 away from the cup body. The cover plate 400 is sleeved on the button 200 and can close the opening of the through cavity 130 away from the cup body under the action of the elastic force it receives. The valve member 300 is located on the side of the button 200 close to the cup body and can close the opening of the through cavity 130 close to the cup body under the action of the elastic force it receives.

[0035] Among them, a protective cover 500 is provided on the mounting base 600, and the end of the protective cover 500 away from the cup body is connected to the cover plate 400. When the button 200 is pressed toward the side close to the cup body, it can drive the cover plate 400 to move toward the side away from the cup body to open the opening of the through cavity 130 away from the cup body, and drive the valve member 300 to move toward the side close to the cup body to open the opening of the through cavity 130 close to the cup body.

[0036] like Figure 3 As shown, when the bottle stopper is in a closed state, the cover plate 400 closes the opening of the through cavity 130 away from the cup body under the action of its own elastic force, the valve member 300 closes the opening of the through cavity 130 close to the cup body under the action of its own elastic force, and the button 200 is in a flush state with the cover plate 400 under the action of its own elastic force;

[0037] like Figure 4 As shown, when the bottle stopper is in the open state, the operator presses the button 200, thereby driving the cover plate 400 to move away from the cup body to open the opening of the through cavity 130 away from the cup body, and at the same time driving the valve member 300 to move toward the cup body to open the opening of the through cavity 130 close to the cup body.

[0038] In the embodiment of the present application, the above-mentioned bottle stopper sealing structure is adopted, and a double sealing structure is adopted. The openings on both sides of the through cavity 130 of the ring part 120 are opened and closed respectively by the valve member 300 and the cover plate 400, thereby effectively improving the anti-leakage and anti-pollution capabilities of the bottle stopper, ensuring the hygiene of the water source and the safety of use. On the other hand, a sheath 500 is arranged between the mounting base 600 and the cover plate 400, so as to seal the gap between the mounting base 600 and the cover plate 400, so as to prevent water from leaking from the gap between the cover plate 400 and the mounting base 600 when pouring water, thereby further improving the sealing performance of the bottle stopper.

[0039] In a preferred embodiment, Figure 1 , Figure 3, Figure 4 As shown, the housing 100 includes an embedding portion 110 and a collar portion 120 fixedly disposed at one end of the embedding portion 110 away from the cup body, and a through cavity 130 is disposed through the embedding portion 110 .

[0040] The collar portion 120 extends toward a side close to the cup body and can be threadedly connected to the cup body. When the collar portion 120 and the cup body are threadedly connected, the embedded portion 110 is located inside the cup body.

[0041] It is understandable that the structural form of the outer shell 100 is not limited to the above one, as long as it can be fixedly connected to the cup body and a through cavity 130 is provided inside, which will not be elaborated here.

[0042] In a preferred embodiment, Figure 3 , Figure 4 As shown, the mounting base 600 includes a bushing 620 fixedly connected to the inner wall of the through cavity 130 and a mounting seat 610 threadedly connected to the bushing 620 and located on a side of the bushing 620 away from the cup body.

[0043] A control cavity 630 with an opening facing a side away from the bushing 620 is provided in the mounting seat 610 , and a control assembly 800 for coupling the button 200 , the valve member 300 , and the cover plate 400 is provided in the control cavity 630 .

[0044] It is understandable that the control component 800 can adopt a driving structure similar to the tip of a ballpoint pen, which has been used in the cup cover of a water cup and belongs to the prior art, so it is not described here. When this structure is adopted, the button 200 can realize the opening of the valve component 300 and the cover plate 400 on both sides of the through cavity 130 after a single press, and realize the automatic reset of the valve component 300 and the cover plate 400 after a second press.

[0045] In a preferred embodiment, Figure 3 , Figure 4 As shown, the valve member 300 includes a valve stem 310 elastically slidably connected to the bushing 620 and coupled to the control assembly 800, and a valve plate 320 fixedly arranged at the end of the valve stem 310 away from the button 200 and capable of closing the opening of the through cavity 130 close to the cup body.

[0046] In a preferred embodiment, Figure 3 , Figure 4 As shown, a sealing ring 700 is fixedly provided at one end of the embedded portion 110 away from the button 200 .

[0047] In the closed state, the end surface of the valve plate 320 close to the button 200 can abut against the sealing ring 700 .

[0048] It can be understood that the sealing ring 700 can further improve the sealing performance of the valve plate 320 to the opening of the through cavity 130 away from the button 200 .

[0049] In a preferred embodiment, Figures 3 to 5 As shown, a connection ring 410 is fixedly provided at one end of the cover plate 400 close to the mounting base 600 , and a travel groove 420 is provided on the outer circumferential surface of the connection ring 410 .

[0050] An inner convex portion 510 is fixedly provided on the inner ring surface of the end of the sheath 500 away from the cup body. The inner convex portion 510 is sleeved at the position of the travel groove 420 of the connecting ring 410 and can abut against the inner wall of the travel groove 420 close to the cup body.

[0051] It can be understood that when the cover 400 moves relative to the mounting base 600 to open and close the through cavity 130, the inner protrusion 510 can slide along the travel groove 420 to adapt to the distance between the cover 400 and the mounting base 600, thereby reducing the pulling deformation of the sheath 500 itself and extending the service life of the sheath 500.

[0052] It should be noted that, in this article, the term "comprises", "includes" or any other variant thereof is intended to cover non-exclusive inclusion, so that the process, method, article or device including a series of elements includes not only those elements, but also includes other elements not explicitly listed, or also includes elements inherent to such process, method, article or device. In the absence of further restrictions, the elements defined by the sentence "including one..." do not exclude the presence of other identical elements in the process, method, article or device including the element.
