Description

Technical Field

[0001] The present invention relates to the field of water cups, and particularly to a lid and a water cup with a push-to-open and close structure. Background Art

[0002] Water cups are drinking utensils commonly used in daily life. A water cup generally includes a cup body and a lid. The lid is used to close the opening of the cup body to prevent the water in the cup body from spilling out. Some of the existing lids are threadedly connected to the cup body through threads, and some are connected to the cup body by deforming a silicone sleeve to disassemble or fix the lid to the cup body. When there is hot water in the cup body, the gas in the cup body increases in pressure due to heat, which sometimes prevents the silicone sleeve from deforming, making it difficult to separate the lid from the cup body. And sometimes, when the high-temperature gas in the cup is discharged outwards after the lid is opened, it may scald the user. Summary of the Invention

[0003] In view of this, the present invention discloses a lid with a push-to-open and close structure, which can discharge the gas in the cup body before the lid is removed from the cup body.

[0004] The present invention discloses a lid with a push-to-open and close structure, which is connected or separated from the cup body through a silicone sleeve. A button and an exhaust column are provided on the lid. The bottom of the exhaust column passes through the bottom surface of the lid through an exhaust hole. A rubber plug is connected to the bottom of the exhaust column, and the exhaust hole is sealed by the rubber plug. The button is located above the exhaust hole and drives the rubber plug to move downward through the exhaust column.

[0005] Further, a locking spring is sleeved on the exhaust column, and the locking spring drives the rubber plug to seal the exhaust hole through the exhaust column.

[0006] Further, the lid includes a main body and a support assembly. The silicone sleeve is arranged outside the main body. The bottom of the silicone sleeve is a deformed part. The support assembly supports the bottom of the deformed part and can drive the deformed part to deform.

[0007] Further, the support assembly includes a support plate and a connecting piece. The connecting piece is located inside the main body.

[0031] As Figure 1 shown, the present invention discloses a lid 100 that can be opened and closed by pressing, which cooperates with a cup body 200 to seal the cup mouth of the cup body 200. A silica gel sleeve 10 is provided on the lid 100, and the silica gel sleeve 10 can be deformed as needed, so that the lid 100 can be detached or fixed to the cup body 200 through the silica gel sleeve 10.

[0032] As Figure 2 and Figure 3As shown, the lid 100 includes a main body 20, an upper lid 30, a button 40, a locking member 50, and a support assembly 60. The upper lid 30 is sleeved outside the main body 20 and is slidably connected to the main body 20 above the main body 20. The silica gel sleeve 10 is arranged outside the main body 20, and the bottom of the silica gel sleeve 10 is a deformed part 11. When the deformed part 11 is normally stretched, the lid 100 can be removed from the cup body 200; when the deformed part 11 of the silica gel sleeve 10 is deformed by force and abuts against the inner wall of the cup body 200, at this time, the lid 100 is fixed on the cup body 200 through the silica gel sleeve 10, and the cup mouth of the cup body 200 is sealed. The support assembly 60 is slidably connected to the main body 20 and is used to support the bottom of the silica gel sleeve 10. The upper lid 30 can drive the support assembly 60 to move upward, so that the deformed part 11 is deformed and abuts against the inner wall of the cup body 200, and the lid 100 is fixed on the cup body 200. The locking member 50 is slidably arranged on the main body 20, and the locking member 50 can lock the support assembly 60. At this time, the deformed part 11 of the silica gel sleeve 10 remains in contact with the cup body 200. The button 40 is slidably connected to the main body 20 and can unlock the support assembly 60 through the locking member 50. At this time, the deformed part 11 of the silica gel sleeve 10 is normally stretched, no longer abuts against the side wall of the cup body 200, and drives the support assembly 60 to reset, and the lid 100 can be removed from the cup body 200. By pressing the button 40 to unlock the support assembly 60, and then making the deformed part 11 normally stretched, the lid 100 can be removed from the cup body 200, and by driving the support assembly 60 to move through the upper lid 30, the deformed part 11 is compressed and deformed, and the lid 100 is fixedly installed on the cup body 200. The user can open or close the lid with one hand, which is simpler in operation compared with the threaded connection method.

[0033] Please refer to Figure 2 , Figure 3 for reference Figure 4, the support assembly 60 includes a support plate 61 and a connecting member 62. The support plate 61 is disposed below the deformation portion 11 to support the deformation portion 11. The bottom end of the connecting member 62 is detachably connected to the support plate 61. The connecting member 62 is located inside the main body 20 and can move vertically relative to the main body 20. When the connecting member 62 drives the support plate 61 to move upward under the action of the upper cover 30, the support plate 61 can apply a force to the deformation portion 11. At this time, the deformation portion 11 deforms under the action of the force, so that the deformation portion 11 abuts against the inner wall of the cup body 200, fixing the lid 100 on the cup body 200. And at this time, the locking member 50 is clamped with the top of the connecting member 62, locking the connecting member 62 at this position. When unlocking is required, press down the button 40. The button 40 drives the locking member 50 to displace relative to the main body 20, so that the locking member 50 no longer clamps and locks the connecting member 62. At this time, the connecting member 62 no longer applies an external force to the deformation portion 11 through the support plate 61, and the deformation portion 11 returns to its normal state, driving the support assembly 60 to reset through the support plate 61. And the deformation portion 11 no longer abuts against the inner wall of the cup body 200. At this time, the lid 100 can be removed from the cup body 200.

[0034] Further, the bottom end of the connecting member 62 is threadedly connected to the support plate 61.

[0035] Please continue to refer to Figure 4 and Figure 5 , further, a first buckle 621 is provided at the top end of the connecting member 62, and a second buckle 51 is provided on the locking member 50. When the connecting member 62 moves upward to a certain distance, the second buckle 51 positions the connecting member 62 through the first buckle 621, and positions the support plate 61 at a corresponding position through the connecting member 62.

[0036] Please continue to refer to Figure 6 , further, the number of the locking members 50 is two, which are symmetrically arranged inside the main body 20 respectively, and the locking members 50 are connected to the main body 20 through return springs 56. The return springs 56 can drive the locking members 50 to be clamped with the connecting member 62.

[0037] Such as Figure 6 and Figure 7As shown, the button 40 is slidably connected to the main body 20. A guiding protrusion 41 is provided on the button 40, and a guiding groove 221 cooperating with the guiding protrusion 41 is provided on the main body 20. When the button 40 moves relative to the main body 20 in the vertical direction through the guiding protrusion 41 and the guiding groove 221. And the guiding groove 221 can position the button 40 through the guiding protrusion 41. When the button 40 moves downward by a certain distance, the guiding groove 221 can prevent the button 40 from continuing to move downward through the guiding protrusion 41.

[0038] As Figures 5 to 7 As shown, a first sliding inclined surface 52 is provided at one end of the locking member 50 away from the return spring 56. The two first sliding inclined surfaces 52 are symmetrically distributed. Second sliding inclined surfaces 42 cooperating with the two first sliding inclined surfaces 52 are respectively provided on both sides of the button 40. When an external force is applied downward to the button 40 to drive the button 40 to move downward relative to the main body 20, the second sliding inclined surface 42 can drive the two locking members 50 to slide to both sides through the first sliding inclined surface 52 until the first buckle 621 no longer engages with the second buckle 51. At this time, the deformation part 11 can be normally unfolded and drive the support assembly 60 to reset. At the same time, the locking member 50 can compress and pre-tighten the return spring 56. When no external force is applied to the button 40, at this time, the return spring 56 will drive the two locking members 50 to reset, and the first sliding inclined surface 52 drives the button 40 to reset through the second sliding inclined surface 42.

[0039] Furthermore, a first card slot 53 is provided on the first sliding inclined surface 52, and a clamping protrusion 43 is provided on the second sliding inclined surface 42. When the first sliding inclined surface 52 is attached to the second sliding inclined surface 42, the clamping protrusion 43 extends into the first card slot 53 and can slide along the first card slot 53. And the first card slot 53 can position the button 40 through the clamping protrusion 43 to prevent the button 40 from leaving the main body 20.

[0040] A third sliding inclined surface 54 is provided at the bottom of the locking member 50. When the connecting member 62 moves upward, the top of the connecting member 62 can drive the two locking members 50 to slide to both sides through the third sliding inclined surface 54 until the first buckle 621 moves above the second buckle 51. At this time, the return spring 56 drives the locking member 50 to reset, and the second buckle 51 prevents the connecting member 62 from moving downward through the first buckle 621.

[0041] The main body 20 includes a main housing 21 and a fixing member 22. The fixing member 22 is disposed within the main housing 21 and is detachably connected to the main housing 21. Further, the fixing member 22 is disposed inside the main housing 21, and both ends of the fixing member 22 are fixedly connected to the main housing 21 through fixing shafts respectively. The locking member 50 is slidably disposed within the fixing member 22. The guiding groove 221 is located on the side wall of the fixing member 22.

[0042] As Figure 4 and Figure 8 shown, an exhaust structure is further provided on the support assembly 60. The exhaust structure includes an exhaust column 64 and an exhaust hole 63. The exhaust hole 63 penetrates through the connecting member 62 and the support plate 61. The bottom end of the exhaust column 64 passes through the exhaust hole 63 and extends below the support plate 61. A rubber plug 65 is connected to the bottom end of the exhaust column 64. The exhaust column 64 can seal the exhaust hole 63 through the rubber plug 65. The top end of the exhaust column 64 extends into the interior of the button 40. The button 40 can drive the exhaust column 64 to move in the vertical direction. When the rubber plug 65 no longer abuts against the support plate 61, the exhaust hole 63 can be opened, and the gas inside the cup body 200 can be discharged through the exhaust hole 63.

[0043] In this embodiment, when the button 40 drives the rubber plug 65 to move downward through the exhaust column 64, the first buckle 621 and the second buckle 51 are still in a clamped state, that is, before the deformation part 11 is normally unfolded, the high-temperature gas inside the cup body 200 can be discharged to the outside through the exhaust hole 63. At this time, it can not only prevent the high-pressure gas in the cup body 200 from preventing the deformation of the deformation part 11, but also prevent the high-temperature gas from scalding the user when the lid 100 is separated from the cup body 200.

[0044] As Figure 7 and Figure 8 shown, further, a connecting portion 641 is provided at the top of the exhaust column 64. The connecting portion 641 extends into the interior of the button 40. A positioning protrusion 642 is provided at the top of the connecting portion 641. A positioning groove 44 that cooperates with the positioning protrusion 642 is provided inside the button 40. The top end of the connecting portion 641 can slide along the positioning groove 44 through the positioning protrusion 642, which can prevent the exhaust column 64 from shaking when sliding relative to the exhaust hole 63.

[0045] A locking spring 66 is sleeved on the exhaust column 64. The bottom end of the locking spring 66 abuts against the connecting member 62, and the top end abuts against the connecting portion 641. The locking spring 66 can apply an upward elastic force to the exhaust column 64 through the connecting portion 641, so that the rubber plug 65 fits against the bottom of the support plate 61 to seal the exhaust hole 63. When exhaust is required, the key 40 drives the exhaust column 64 to move downward through the connecting portion 641, and the rubber plug 65 moves downward by a certain distance accordingly. At this time, the exhaust hole 63 is opened for exhaust. When no downward pressure is applied to the key 40, the locking spring 66 can drive the exhaust column 64 to move upward through the connecting portion 641 until the rubber plug 65 abuts against the bottom of the support plate 61 to seal the exhaust hole 63.

[0046] Please refer to Figure 2 , Figure 3 and Figure 9 When the deformation part 11 of the silica gel sleeve 10 is normally stretched to drive the support assembly 60 to move downward, so that the lid 100 opens the cup mouth of the cup body 200, the connecting member 62 can drive the upper lid 30 to move upward relative to the main body 20 through the link assembly 70. When it is necessary to fix the lid 100 on the cup body 200, press down the upper lid 30. The upper lid 30 drives the support assembly 60 to move upward through the link assembly 70, drives the deformation part 11 to deform through the support plate 61 and abuts against the inner wall of the cup body 200.

[0047] Furthermore, the link assembly 70 includes a first link 71 and a second link 72. The first link 71 and the second link 72 are both located inside the main housing 21 and are respectively located on both sides of the fixing member 22 to wrap the fixing member 22.

[0048] Please continue to refer to Figure 9 and Figure 10, the first connecting rod 71 and the second connecting rod 72 are respectively rotatably connected to the fixing member 22 through a rotating shaft 73. One end of the first connecting rod 71 away from the rotating shaft 73 and one end of the second connecting rod 72 away from the rotating shaft 73 are respectively located on both sides of the fixing member 22 and are in contact with the bottom end of the upper cover 30. The top of the connecting member 62 is connected with a connecting shaft 74. Both ends of the connecting shaft 74 respectively pass through the side wall of the fixing member 22 and are respectively matched with the first connecting rod 71 and the second connecting rod 72 through kidney-shaped holes 75. In this embodiment, the connecting shaft 74 is located at the middle position between the first connecting rod 71 and the second connecting rod 72. When the deformation part 11 is normally unfolded and drives the support assembly 60 to move downward, the connecting member 62 drives the first connecting rod 71 and the second connecting rod 72 to rotate around the rotating shaft 73 through the connecting shaft 74 at the same time, so that the ends of the first connecting rod 71 and the second connecting rod 72 located on both sides of the fixing member 22 are tilted up, jacking up the upper cover 30 until the deformation part 11 is completely unfolded. At this time, the lid 100 can be removed from the cup body 200. When it is necessary to fix the lid 100 on the cup body 200, press the upper cover 30. At this time, the bottom end of the upper cover 30 applies a downward force to the ends of the first connecting rod 71 and the second connecting rod 72 located on both sides of the fixing member 22, so that the first connecting rod 71 and the second connecting rod 72 rotate around the rotating shaft 73. At this time, the first connecting rod 71 and the second connecting rod 72 drive the connecting member 62 to move upward through the connecting shaft 74, and then apply an upward force to the deformation part 11 through the support plate 61, so that the deformation part 11 deforms and abuts against the inner wall of the cup body 200, fixing the lid 100 on the cup body 200.

[0049] The kidney-shaped holes 75 are respectively arranged on the first connecting rod 71 and the second connecting rod 72. The connecting shaft 74 is respectively matched with the first connecting rod 71 and the second connecting rod 72 through the kidney-shaped holes 75. When the first connecting rod 71 and the second connecting rod 72 rotate around the rotating shaft 73, the kidney-shaped holes 75 can move relative to the connecting shaft 74, so that the first connecting rod 71 and the second connecting rod 72 can rotate around the rotating shaft 73 normally.

[0050] The first link 71 and the second link 72 respectively include a first connecting edge 711, a second connecting edge 712 and a third connecting edge 713. The first connecting edge 711 and the second connecting edge 712 are respectively located on both sides of the fixing member 22, and the first connecting edge 711 and the second connecting edge 712 are connected by the third connecting edge 713. The first connecting edge 711 and the second connecting edge 712 are both provided with the rotating shaft 73, and are rotatably connected to the fixing member 22 through the rotating shaft 73. The axes of the two rotating shafts 73 on the same link are on the same straight line. The third connecting edge 713 contacts the bottom surface of the upper cover 30. When the first connecting edge 711 and the second connecting edge 712 rotate around the rotating shaft 73, the upper cover 30 can be abutted through the third connecting edge 713. In this embodiment, the kidney-shaped hole 75 is located on the first connecting edge 711, and the kidney-shaped holes 75 on the first link 71 and the second link 72 are respectively located on both sides of the fixing member 22.

[0051] As Figure 9 and Figure 11 shown, further, at least one stop strip 31 is provided inside the upper cover 30. The stop strip 31 is provided with a first stop buckle 32. A stop groove 211 that cooperates with the stop strip 31 is provided inside the main housing 21. The stop strip 31 slides in the stop groove 211, so that the upper cover 30 can move smoothly relative to the main body 20. A second stop buckle 212 that prevents the first stop buckle 32 from moving upward continuously is provided at the top of the stop groove 211, which can prevent the upper cover 30 from detaching from the main body 20.

[0052] As Figure 3 and Figure 11 shown, a second card slot 55 is provided on the locking member 50. A third buckle 33 that cooperates with the second card slot 55 is provided inside the upper cover 30. When the upper cover 30 drives the support assembly 60 to move upward through the link assembly 70 until the connecting member 62 is engaged with the locking member 50, the third buckle 33 is engaged with the second card slot 55. At this time, the lid 100 is fixedly connected to the cup body 200 through the deformed portion 11 of the silica gel sleeve 10, and the upper cover 30 is also engaged with the main housing 21. At this time, the upper cover 30 cannot move relative to the main body 20. When a downward pressure is applied to the button 40, the button 40 drives the two locking members 50 to move to both sides until the third buckle 33 is separated from the second card slot 55. At this time, the upper cover 30 can move relative to the main body 20.

[0053] A key slot 34 that cooperates with the key 40 is further provided on the upper cover 30. When the lid 100 is connected to the cup body 200, the key 40 is located in the key slot 34.

[0054] The present invention also discloses a water cup, including the above-mentioned lid 100 and cup body 200. The lid 100 is used to close the cup mouth of the cup body 200. A convex portion that cooperates with the deformation portion 11 is provided inside the cup body 200. When the deformation portion 11 deforms, it can abut against the convex portion on the inner wall of the cup body 200, thereby fixing the lid 100 on the cup body 200.

[0055] During use:

[0056] When removing the lid 100 from the cup body 200, a downward force is applied to the key 40. The key 40 first drives the rubber plug 65 to move downward through the exhaust column 64, so that the exhaust hole 63 is opened. At this time, the gas in the cup body 200 can be discharged through the exhaust hole 63, reducing the air pressure in the cup body 200. Then the key 40 continues to move downward, so that the two locking members 50 move to the corresponding positions on both sides respectively. At this time, the first buckle 621 is separated from the second buckle 51, and the third buckle 33 is separated from the second card slot 55. At this time, the deformation portion 11 of the silica gel sleeve 10 is normally stretched, and can drive the connecting member 62 to move downward through the support plate 61. The deformation portion 11 no longer abuts against the inner wall of the cup body 200, and the lid 100 can be removed from the cup body 200. And when the connecting member 62 moves downward, it can drive the first connecting rod 71 and the second connecting rod 72 to rotate around the rotating shaft 73 through the connecting shaft 74, so that the two third connecting edges 713 are tilted up, driving the upper cover 30 to move upward a certain distance.

[0057] When fixing the lid 100 on the cup body 200, a certain pressure is applied to the upper cover 30. The upper cover 30 drives the first connecting rod 71 and the second connecting rod 72 to rotate around the rotating shaft 73 through the two third connecting edges 713. The first connecting rod 71 and the second connecting rod 72 drive the connecting member 62 to move upward through the connecting shaft 74. At the same time, the support plate 61 applies an external force to the deformation portion 11 under the action of the connecting member 62, so that the deformation portion 11 deforms and abuts against the inner wall of the cup body 200, fixing the lid 100 on the cup body 200. At this time, the first buckle 621 moves above the second buckle 51, and the locking member 50 positions the connecting member 62 through the first buckle 621. The second card slot 55 positions the upper cover 30 through the third buckle 33.

[0058] Without departing from the broad spirit and scope of the present invention, it can be embodied in various forms and modifications. The above embodiments are used to illustrate the invention, but do not limit the scope of the present invention.
