[0046] The following uses specific examples to illustrate the implementation manners of the present invention. Those skilled in the art can easily understand other advantages and effects of the present invention from the content disclosed in this specification. The present invention can also be implemented or applied through other different specific implementation manners. Various details in this specification can also be modified or changed based on different viewpoints and applications without departing from the spirit of the present invention.

[0047] It should be noted that the illustrations provided in this embodiment only schematically illustrate the basic concept of the present invention. Therefore, only the components related to the present invention are shown in the drawings, rather than being drawn according to the number, shape, and size of the components in actual implementation. The type, quantity, and ratio of each component in actual implementation can be arbitrarily changed, and the component layout type may also be more complex.

[0048] In the existing sealing methods for the water outlet, the general design is only a hinged and pressable sealing cover at the outlet position, and an opening button is provided on the side wall between the sealing cover and the cup lid. By pressing the button, the sealing cover can be bounced open around the axis under the action of the torsion spring, and then the sealing cover is rotated and pressed to combine with the cup lid to achieve their closing. The above connection method between the sealing cover and the cup lid, although it can facilitate operation, when the user is driving or inconvenient to observe the cup lid, the user needs to touch the side wall button on the cup lid to open the sealing cover, which is not convenient for blind operation. Moreover, in the way that the sealing cover bounces open around the hinge axis, the liquid flow on the sealing cover will splash after the sealing cover bounces into place. In addition, in the opening method of this sealing cover, when the sealing cover bounces open, there needs to be enough space in the vertical space. Once it is used in a narrow subway, car, or other public places, this method has certain disadvantages. Therefore, the present invention proposes an improved solution to solve the existing problems. The cup lid includes: a lid body 10; a liquid outlet channel 11 is provided through it; an inner plug body 20 is movably installed inside the lid body 10 and is assembled to be able to switch between two states of blocking and opening the entrance of the liquid outlet channel 11; an outer rotating body 30 is movably installed outside the lid body 10 and is assembled to be able to switch between two states of blocking and opening the exit of the liquid outlet channel 11.

[0049] Refer to Figure 1 andFigure 2 There are two states. In a preferred embodiment, an operation end is provided on the inner plug body 20. The operation end is installed at the central position of the cover body 10, and the operation end is assembled to be movable along the central axis direction of the cover body 10.

[0050] In an embodiment, when the operation end of the inner plug body 20 is installed at the central position of the cover body 10, when opening the inlet of the liquid outlet channel 11 of the inner plug body 20 and the cover body 10, by pressing the operation end, the inner plug body 20 can be moved along the central axis direction of the cover body 10. In this embodiment, the operation end for opening the liquid outlet channel 11 is arranged at the central position of the cover body 10, which is convenient for the user's blind operation. The user only needs to touch the center of the cover body 10 with the hand and press it once to open the liquid outlet channel 11. Moreover, in actual operation, this way of blocking the liquid outlet channel 11 replaces the existing elastic opening method, avoiding the splashing of liquid, and is very suitable for use when driving or in a narrow space.

[0051] In an embodiment, refer to Figure 4 、 Figure 10 and Figure 11 The outer rotating body 30 is integrally sheet-shaped. One end of the outer rotating body 30 is installed at the central position of the cover body 10. One end of the outer rotating body 30 is assembled to be rotatable around the central axis of the cover body 10, and the central axis of the cover body 10 is perpendicular to the plate surface of the outer rotating body 30.

[0052] In an embodiment, a dust-proof cover is arranged at the outlet position of the liquid outlet channel 11. On the one hand, it can block the outlet of the liquid outlet channel 11 to prevent foreign objects from entering the liquid outlet channel 11. On the other hand, by operating the outer rotating body 30 to rotate around the central axis of the cover body 10, in actual operation, blind operation can also be realized, and the central axis of the cover body 10 is perpendicular to the plate surface of the outer rotating body 30. That is, the sheet-shaped structure of the outer rotating body 30 fits on the upper end surface of the cover body 10. While the operation is convenient, the opening size in the length direction of the cup cover is smaller, and the problem of elastic opening and splashing when the liquid outlet channel 11 is opened can also be avoided.

[0053] In an embodiment, a linkage unit is arranged between the inner plug body 20 and the outer rotating body 30. The linkage unit is assembled to enable the inner plug body 20 and the outer rotating body 30 to present two linkage states. One is that the operation end of the inner plug body 20 moves along the central axis direction of the cover body 10, and through the linkage unit, one end of the outer rotating body 30 is rotated around the center of the cover body 10, and the outer rotating body 30 is far from the outlet of the liquid outlet channel 11. The other is that the outer rotating body 30 is rotated around the center of the cover body 10 and approaches the outlet of the liquid outlet channel 11, and through the linkage unit, the operation end of the inner plug body 20 extends out of the central position of the cover body 10.

[0054] In one embodiment, see Figure 10 、 Figure 16 and Figure 17 When the cup cover is actually used, the inner blocking body 20 is moved along the central axis direction of the cover body 10 by pressing the inner blocking body 20 provided at the center position of the cover body 10, and one end of the outer rotating body 30 is rotated around the center of the cover body 10 by the linkage unit, so that the outer rotating body 30 is away from the outlet of the liquid outlet channel 11, and the inner blocking body 20 is away from the inlet of the liquid outlet channel 11, thereby forming a liquid flow channel for the liquid outlet channel 11 to facilitate drinking the liquid in the cup body; when the inlet and outlet of the liquid outlet channel 11 need to be closed, the outer rotating body 30 is rotated around the center of the cover body 10 so that the outer rotating body 30 is close to the outlet of the liquid outlet channel 11. When the outer rotating body 30 is close to the outlet of the liquid outlet channel 11, the operating end of the inner blocking body 20 is extended out of the center of the cover body 10 by the linkage unit, so that the inner blocking body 20 and the inlet of the liquid outlet channel 20 are close to each other, thereby blocking the inlet and outlet of the liquid outlet channel 20.

[0055] In a specific embodiment of the present invention, a pipe 12 is provided at the center of the cover body 10, and the operating end of the inner blocking body 20 is slidably provided in the pipe 12. An exhaust unit is provided between the operating end of the inner blocking body 20 and the pipe 12. When the operating end of the inner blocking body 20 is pressed and moved along the pipe 12, the exhaust unit opens and the pipe 12 is made conductive.

[0056] In one embodiment, in order to ensure the safe use of the cup body and avoid safety problems caused by high-temperature liquid splashing out of the liquid outlet channel 11 when opening, an exhaust unit is provided between the operating end of the inner blocking body 20 and the pipe 12. When the liquid outlet channel 11 of the cup cover is opened, the operating end of the inner blocking body 20 moves along the pipe 12, so that the exhaust unit is opened, and the pipe 12 can be made conductive. Then, in the actual process of pressing the inner blocking body 20 to open, the gas inside the cup body can be discharged, thereby ensuring the safe use of the cup.

[0057] In a specific embodiment of the present invention, in order to implement the installation of various components, a sink 121 is provided at the center of the cover body 10, and the pipe 12 is provided at the bottom of the sink 121;

[0058] In one embodiment, see Figure 7 、 Figure 8 and Figure 9, one end of the pipeline 12 located in the sink 121 is provided with a transition body 13. The transition body 13 is integrally tubular. One end of the transition body 13 is provided with an annular opening 131 that forms a plug-in fit with one end of the pipeline 12. A positioning protrusion 132 is arranged in the annular opening 131. A positioning notch 124 is arranged at the pipe orifice position of the pipeline 12. The positioning protrusion 132 is inserted into the positioning notch 124. Two groups of fixing notches 133 are symmetrically arranged on the inner wall of the transition body 13 at the bottom of the annular opening 131. A fixing protrusion 122 is arranged on the inner wall of the pipeline 12. The fixing protrusion 122 extends into the fixing notch 133. A supporting ring 134 is further arranged on the outer wall of the transition body 13.

[0059] In one embodiment, referring to Figure 9 , to facilitate the installation of the outer rotating body 30 and the inner plug body 20, a sink 121 is arranged at the center of the cover body 10. The pipeline 12 is arranged at the bottom of the sink 121, and both the upper and lower ends protrude from the bottom of the sink 121. A transition body 13 is arranged in the cavity of the pipeline 12 protruding from the sink 121, which is convenient for arranging the linkage units included in the subsequent outer rotating body 30 and inner plug body 20.

[0060] One end of the above-mentioned transition body 13 is provided with an annular opening 131 that forms a plug-in fit with one end of the pipeline 12. A positioning protrusion 132 is arranged in the annular opening 131, which can reliably position the transition body 13 and prevent the transition body 13 from rotating on the pipeline 12. By inserting the fixing protrusion 122 into the fixing notch 133, the fixing of the transition body 13 and the pipeline 12 is realized, and the installation of the transition body 13 and the pipeline 12 is completed. Due to the special structure of the transition body 13, it cannot be formed by an injection mold. Therefore, the transition body 13 and the cover body 10 are of a split structure, which is convenient for disassembly and installation and also convenient for cleaning.

[0061] In one embodiment of the present invention, referring to Figure 10 and Figure 11 , one end of the outer rotating body 30 extends to be provided with a rotating pipe 31. The rotating pipe 31 is rotatably arranged in the sink 121 and one end is inserted into the pipe orifice position of the pipeline 12; the linkage unit includes a linkage torsion spring 41 sleeved on the outer wall of the pipeline 12. The two ends of the linkage torsion spring 41 are respectively connected to the rotating pipe 31 and the pipe body of the transition body 13.

[0062] In one embodiment, when the outer rotating body 30 rotates around the central sink 121 of the cover body 10, one end of the outer rotating body 30 approaches the outlet of the liquid outlet channel 11, thereby compressing the interlocking torsion spring 41. When the operating end of the inner plug body 20 is pressed, the inner plug body 20 moves downward along the pipe 12. Under the elastic restoring force of the interlocking torsion spring 41, under the restoring force of the outer rotating body 30, the outer rotating body 30 rotates around the central sink 121 of the cover body 10 away from the outlet of the liquid outlet channel 11, and the inner plug body 30 synchronously moves away from the inlet of the liquid outlet channel 11 until the liquid outlet channel 11 is opened.

[0063] In a specific embodiment of the present invention, referring to Figure 11 and Figure 12 , the interlocking unit further includes a guiding protrusion 311 provided on the inner wall of the rotating pipe 31; a pressing cover 21 is provided at the operating end of the inner plug body 20 extending out of one end of the pipe 12, and the pressing cover 21 is integrally circular tubular and arranged inside the rotating pipe 31; the interlocking unit further includes a guiding limiting groove 211 provided on the outer wall of the pressing cover 21, and the guiding limiting groove 211 includes a vertical groove 2111 and an annular groove 2112. The vertical groove 2111 is arranged along the length direction of the outer wall of the pressing cover 21, and the annular groove 2112 is arranged along the circumferential direction of the pressing cover 21. One end of the vertical groove 2111 and the annular groove 2112 communicate and form an "L" shape. The interlocking unit further includes a supporting spring 42 provided at the pipe orifice at one end of the transition body 13, and both ends of the supporting spring 42 respectively abut against the supporting ring 134 of the transition body 13 and the bottom of the pressing cover

[0064] In a specific embodiment, referring to Figure 16 and Figure 17 , when the outer rotating body 30 rotates around the central sink 121 of the cover body 10, the guiding protrusion 311 slides in the annular groove 2112 of the guiding limiting groove 211, so that one end of the outer rotating body 30 approaches the outlet of the liquid outlet channel 11 until the guiding protrusion 311 slides to the position of the vertical groove 2111, and the interlocking torsion spring 41 is compressed. Under the restoring force of the supporting spring 42, the pressing cover 21 is restored to the upper pipe orifice position of the pipe 12 under the elastic force. At this time, the guiding protrusion 311 extends into the vertical groove 2111, and one side surface of the guiding protrusion 311 abuts against one side groove wall of the vertical groove 2111, implementing the limit of the rotating pipe 31, the constraint of the restoring force of the torsion spring 41, and realizing the sealing of the inlet and outlet of the liquid outlet channel 11 by the inner plug body 20 and the outer rotating body 30.

[0065] In a specific embodiment, referring to Figure 16 and Figure 17, when pressing the operating end of the inner plug 20, the inner plug 20 moves downward along the pipeline 12 until the guiding protrusion 311 slides along the vertical groove 2111 to the position of one end notch of the annular groove 2112, releasing the restoring force of the interlocking torsion spring 41. Under the elastic restoring force of the interlocking torsion spring 41, the outer rotating body 30 rotates, causing the outer rotating body 30 to rotate away from the outlet of the liquid outlet channel 11 around the central sink 121 of the cover body 10. When the guiding protrusion 311 is located in the annular groove 2112, the lower plate surface of the guiding protrusion 311 abuts against the lower groove wall of the annular groove 2112 to constrain the elastic compression force of the support spring 42. At this time, the inner plug 20 also moves away from the inlet of the liquid outlet channel 11 synchronously until the liquid outlet channel 11 is opened. According to the above actions, covering or conducting the inlet and outlet of the liquid outlet channel 11 can be realized.

[0066] In a specific embodiment, referring to Figure 13 , Figure 14 and Figure 15 , an insertion pipe 212 is provided at the center of the bottom of the pressing cover 21; the inner plug 20 further includes a plugging head 22, and the plugging head 22 includes a plugging end 221 and a mounting end 222, and the plugging end 221 cooperates with the inlet of the liquid outlet channel 11.

[0067] In an embodiment, referring to Figure 14 , the plugging end 221 and the mounting end 222 are integrally in a folded plate shape. An opening is provided on the plugging end 221, and a sealing silica gel 223 is arranged in the opening. The sealing silica gel 223 extends out of the opening and abuts against or separates from the inlet of the liquid outlet channel 11. The sealing silica gel 223 and the opening form a pressing fit, which is convenient for disassembly and installation. When the sealing silica gel 223 is dirty or damaged, it can be disassembled for cleaning or replacement.

[0068] In an embodiment, the mounting end 222 is integrally tubular and is installed at one end of the plugging head 22. The mounting end 222 is placed in the pipeline 12, and the insertion pipe 212 and the pipe orifice of the mounting end 222 form an insertion and sliding fit.

[0069] In an embodiment, referring to Figure 13 and Figure 14 , sliding grooves 2121 are provided on both sides of the outer wall of the insertion pipe 212, and positioning blocks 2223 are provided at the pipe orifice of the mounting end 222. When the insertion pipe 212 and the pipe orifice of the mounting end 222 are inserted, the positioning blocks 2223 are inserted into the sliding grooves 2121 to realize the positioning installation of the insertion pipe 212 and the mounting end 222.

[0070] In a specific embodiment, the plugging end 221 and the insertion pipe 212 are fixedly connected by screws.

[0071] Specifically, screws are provided at the lower end pipe orifice of the plugging end 221. The screws and the pipe orifice of the insertion pipe 212 form a threaded connection and cooperation, so as to realize the installation connection between the plugging section 221 and the insertion pipe 212.

[0072] A limiting plate 14 is arranged inside the cover body 10. The limiting plates 14 are distributed on both sides of the plugging end 221 to limit the limiting plates 14 and prevent the limiting plates 14 from rotating.

[0073] When the pressing cover 21 is pressed to perform the exhaust operation on the cup body 50, an annular groove 2221 is arranged on the outer wall of the installation end 222, and an annular sealing ring 2222 is arranged in the annular groove 2221. The annular sealing ring 2222 and the inner wall of the pipeline 12 form a sealing fit; the exhaust unit includes an exhaust notch urchin arranged on the inner wall of the pipeline 12, and the exhaust notch urchin is arranged along the length direction of the pipeline 12;

[0074] Refer to Figure 16 and Figure 17 , when the installation end 222 slides along the pipeline 12, there are two states where the lower end surface of the annular sealing ring 2222 is higher than the upper end of the exhaust notch urchin or the upper end surface of the annular sealing ring 2222 is lower than the upper end of the exhaust notch urchin.

[0075] In an embodiment, when the lower end surface of the annular sealing ring 2222 is higher than the upper end of the exhaust notch urchin, the pressing cover 21 is reset. At this time, the annular sealing ring 2222 forms a seal for the pipeline 12. When the upper end surface of the annular sealing ring 2222 is lower than the upper end of the exhaust notch urchin, the liquid outlet channel 11 is in a state to be opened at this time, and the gas in the cup body 50 can be discharged in advance to avoid splashing and ensure the safe use of the cup.

[0076] In summary, when the cup cover of the present invention is actually used, a liquid outlet channel 11 is arranged on the cover body 10, and an inner plug body 20 is movably installed inside the cup cover, so that the inner plug body 20 can block or open the inlet of the liquid outlet channel 11. An outer rotating body is movably installed outside the cover body 10, and by operating the outer rotating body, the outlet of the liquid outlet channel 11 can be blocked or opened. The inner plug body 20 used by the cup cover can conveniently operate to open or close the liquid outlet channel 11, and the application of the outer rotating body 30 can effectively prevent foreign objects from entering the liquid outlet channel, and by operating the outer rotating body 30, the inner plug body 20 can be reset. Therefore, when the cup cover is actually used, it has high use convenience and flexible operation.

[0077] The above description is only a preferred embodiment of the present application and an explanation of the applied technical principles.
