[0005] An outer cover, wherein a fixing ring is connected to the upper portion of the outer cover;

[0006] An inner plug, disposed below the outer cover and detachably connected to the outer cover;

[0007] A button is installed between the fixing ring and the outer cover and can move along the axial direction of the outer cover to lock or release the inner plug.

[0008] The cup cover provided by the present application includes an outer cover, an inner plug and a button. The outer cover is used to connect the cup body, and a fixing ring is connected to the top of the outer cover; the inner plug is arranged below the outer cover, and the inner plug is used to seal the cup body, and the inner plug is detachably connected to the outer cover; the button is installed between the fixing ring and the outer cover, and the button can move along the axial direction of the outer cover to lock or release the inner plug; when the button locks the inner plug, the inner plug and the outer cover are relatively fixed, thereby ensuring that the inner plug and the outer cover form a stable and reliable connection, preventing the inner plug from loosening or falling off during use, and affecting the sealing performance between the cup cover and the water cup; when the button releases the inner plug, the inner plug and the outer cover can be normally disassembled, thereby meeting the needs of disassembling and cleaning the inner plug, and improving the convenience of cleaning the cup cover. In addition, the embodiment of the present application only disassembles the inner plug that is in direct contact with the liquid, which can not only meet the needs of disassembling and cleaning the cup cover, but also reduce the number of disassembled parts as much as possible, thereby simplifying the cleaning operation of the cup cover, and reducing the risk of disassembling and losing parts, further improving the use experience of the cup cover.

[0009] Optionally, a connection hole is provided in the center of the outer cover, and a connection column is provided in the center of the inner plug, and the connection column is inserted into the connection hole and snapped onto the hole wall of the connection hole. The connection column and the connection hole form a detachable connection, which is reliable, easy to assemble and disassemble, and is not affected by the shape of the cup cover itself, and has high versatility.

[0010] Optionally, the hole wall of the connecting hole is provided with a slide groove, the slide groove extends along the axial direction of the outer cover, and the slide groove is provided with a card slot on one side along the circumference of the outer cover; the outer circumference of the connecting column is provided with a card convex, the card convex is inserted into the slide groove, and is screwed into or out of the card slot as the inner plug rotates. On the one hand, the card convex and the slide groove cooperate with each other, so as to form circumferential positioning and axial guidance between the inner plug and the outer cover, increase the stability of the inner plug during installation, prevent the inner plug and the outer cover from rotating relative to each other, affect the normal cooperation between the card convex and the card slot, and further affect the installation and removal of the inner plug; on the other hand, the card slot and the slide groove are connected to each other, and the card convex is screwed into the card slot from the slide groove, avoiding interference between the card convex and other parts, reducing the deformation or avoidance requirements of the card convex, so that the card convex can adopt a rigid structure, the card convex and the card slot can form a rigid cooperation, and increase the reliability of the inner plug connection.

[0011] Optionally, a locking portion is provided below the button, and the locking portion is provided between the card slot and the slide slot, and the locking portion stops the card protrusion or avoids the card protrusion as the button moves. The inner plug is locked by stopping the card protrusion, and is released by avoiding the card protrusion. The structure is simple, the action is simple and efficient, and the coordination or connection between the locking portion and other components can be reduced, thereby simplifying the overall structure of the cup cover and reducing production costs.

[0012] Optionally, a guide surface is provided on the top of the locking portion, and the height of the guide surface gradually increases in the direction away from the slide groove. When the locking protrusion is screwed from the slide groove into the locking groove, the locking protrusion and the guide surface abut against each other, and the guide surface converts the circumferential movement of the locking protrusion into the axial movement of the locking portion, thereby forcing the locking portion to automatically avoid the locking protrusion. In other words, when installing the inner plug, there is no need to manually operate the button to avoid the locking protrusion, which further simplifies the installation operation of the inner plug and improves the user experience of the cup cover.

[0013] Optionally, a guide groove is provided at a position of the outer cover facing the locking portion, and the guide groove extends along the axial direction of the outer cover; at least a portion of the locking portion is inserted into the guide groove and slides along the guide groove.

[0014] Optionally, a connecting groove is provided between the card slot and the slide groove, and the card protrusion is screwed into or out of the card slot along the connecting groove, and the connecting groove is higher than the card slot to form a stop step. This increases the difficulty of the card protrusion escaping from the card slot, and serves as a double insurance function, that is, even if the button fails accidentally to loosen the inner plug, the card protrusion is difficult to screw out of the card slot under the action of the stop step, thereby effectively reducing the possibility of the inner plug loosening or falling off during use.

[0015] Optionally, an elastic member is provided inside the outer cover, and one end of the elastic member passes through the outer cover and abuts against the upper surface of the inner plug. On the one hand, the elastic member is located inside the outer cover, and the elastic member will not fall off during the removal of the inner plug, which can reduce the number of parts to be disassembled and assembled when cleaning the cup cover and improve the convenience of cleaning the cup cover, and can also prevent the elastic member from popping out or falling off during the removal of the inner plug, resulting in missing parts, and effectively extend the service life of the cup cover. On the other hand, under the action of the elastic member, the cover body and the outer cover have a tendency to separate from each other, which can not only push the inner plug downward during the removal of the inner plug, making the removal of the inner plug more convenient and labor-saving, but also push the outer cover upward during the opening of the cup cover, making the opening operation more convenient and labor-saving.

[0016] Optionally, the outer cover is provided with an active buckle, which is used to connect the cup body; the active buckle and the button abut against each other, and the button drives the active buckle to move to achieve buckling or disengagement. The user only needs to apply external force to the button to move the button along the axial direction of the outer cover, so as to control the active buckle to open the cup cover, which is convenient to open and improves the user experience.

[0017] Optionally, the middle part of the movable buckle is rotatably connected to the outer cover; a part of the movable buckle extends radially along the outer cover and is connected to the button; another part of the movable buckle extends axially along the outer cover and is formed with a claw, and the button drives the claw to open or clamp. The button acts on the movable buckle through the principle of leverage, converting the axial movement of the button into the rotation of the movable buckle, making the overall layout more flexible and compact, improving space utilization, and thus reducing the overall volume of the cup cover.

[0018] Optionally, an exhaust hole is provided in the center of the inner plug, and an exhaust sealing ring is installed in the exhaust hole; an exhaust rod is provided under the button, and the exhaust rod cooperates with the exhaust sealing ring to open or close the exhaust hole, which can meet both the sealing requirements of the liquid and the exhaust requirements of opening the lid.

[0019] A second aspect of the present application provides a water cup, which comprises a cup body and any one of the cup covers provided in the present application, wherein the cup cover is detachably connected to the cup body.

[0054] The accompanying drawings, which are incorporated in and constitute a part of this specification, illustrate embodiments consistent with the present application and, together with the description, serve to explain the principles of the present application. DETAILED DESCRIPTION

[0055] In order to make the purpose, technical solution and advantages of the present application more clearly understood, the present application is further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present application and are not used to limit the present application.

[0056] In the description of this application, unless otherwise clearly specified and limited, the terms "first" and "second" are used for descriptive purposes only and cannot be understood as indicating or implying relative importance; unless otherwise specified or explained, the term "plurality" refers to two or more; the terms "connected" and "fixed" should be understood in a broad sense, for example, "connected" can be a fixed connection, a detachable connection, an integral connection, or an electrical connection; it can be directly connected or indirectly connected through an intermediate medium. For ordinary technicians in this field, the specific meanings of the above terms in this application can be understood according to specific circumstances.

[0057] In the description of this specification, it should be understood that the directional words such as "upper" and "lower" described in the embodiments of the present application are described at the angles shown in the accompanying drawings and should not be understood as limiting the embodiments of the present application. In addition, in the context, it should also be understood that when it is mentioned that an element is connected to another element "upper" or "lower", it can not only be directly connected to another element "upper" or "lower", but also indirectly connected to another element "upper" or "lower" through an intermediate element.

[0058] like Figure 1-Figure 6As shown, an embodiment of the present application provides a cup cover 01, which can be connected to a cup body 02 and close the opening of the cup body 02, so that the cup cover 01 and the cup body 02 together form a water cup capable of holding liquid. The cup cover 01 includes an outer cover 1, an inner plug 2 and a button 4. The outer cover 1 is used to connect the cup body 02, and a fixing ring 3 is connected to the top of the outer cover 1; the inner plug 2 is arranged at the bottom of the outer cover 1, and the inner plug 2 is used to seal the cup body 02, and the inner plug 2 is detachably connected to the outer cover 1; the button 4 is installed between the fixing ring 3 and the outer cover 1, to increase the stability and reliability of the connection of the button 4, to prevent the button 4 from being damaged or falling off during use, and the button 4 can move along the axial direction of the outer cover 1 to lock or release the inner plug 2; when the button 4 locks the inner plug 2, the inner plug 2 and the outer cover 1 are relatively fixed, thereby ensuring that the inner plug 2 forms a stable and reliable connection with the outer cover 1, to prevent the inner plug 2 from loosening or falling off during use, affecting the sealing performance between the cup cover 01 and the water cup; when the button 4 releases the inner plug 2, the inner plug 2 and the outer cover 1 can be disassembled normally, thereby meeting the needs of disassembling and cleaning the inner plug 2 and improving the convenience of cleaning the cup cover 01. In addition, the embodiment of the present application only disassembles the inner plug 2 that is in direct contact with the liquid, which can not only meet the needs of disassembling and cleaning the cup cover 01, but also minimize the number of disassembled parts, thereby simplifying the cleaning operation of the cup cover 01 and reducing the risk of loss of disassembled parts, further improving the user experience of the cup cover 01.

[0059] Specifically, the outer cover 1 and the inner plug 2 can be connected to each other in any appropriate detachable manner, such as a threaded manner or a snap-fit ​​manner, etc. The button 4 can lock the inner plug 2 in any appropriate manner, such as a latch lock, a clutch lock, or a friction lock, etc., as long as repeated locking and release can be achieved.

[0060] The fixing ring 3 is detachably connected to the top of the outer cover 1. For example, the fixing ring 3 can be connected to the top of the outer cover 1 by snap fit or thread fit to facilitate the removal and replacement of the button 4. The fixing ring 3 stops at the top of the button 4, so that the button 4 is sandwiched between the outer cover 1 and the fixing ring 3 to prevent the button 4 from falling off the fixing ring 3. A part of the button 4 is exposed to the inner ring of the fixing ring 3, thereby forming a pressing operation area for the user. It can be understood that the cup cover 01 may not be provided with a fixing ring 3, and the button 4 is directly connected to the outer cover 1 by snap fit or other means.

[0061] Furthermore, a reset member 5 can be provided between the button 4 and the outer cover 1. The reset member 5 can be any appropriate component such as a spring, and the two ends of the reset member 5 elastically press against the button 4 and the top of the outer cover 1. When the user releases the button 4, the button 4 can automatically bounce up and reset under the action of the reset member 5, making the operation more convenient. It can be understood that the button 4 can also be manually reset by manually lifting it.

[0062] Furthermore, a connecting hole 11 is provided in the center of the outer cover 1, and a connecting column 21 is provided in the center of the inner plug 2. The connecting column 21 and the connecting hole 11 form a detachable connection, which is reliable, easy to assemble and disassemble, and is not affected by the appearance of the cup cover 01 itself, and has high versatility. The connecting column 21 is inserted into the connecting hole 11, so that the inner plug 2 and the outer cover 1 form a radial limit to prevent the inner plug 2 and the outer cover 1 from being misaligned; the connecting column 21 is buckled on the hole wall of the connecting hole 11, so that the inner plug 2 and the outer cover 1 form an axial limit to prevent the inner plug 2 and the outer cover 1 from being separated from each other.

[0063] Specifically, one of the connection column 21 and the connection hole 11 has an outwardly convex protrusion 211 on its circumferential surface, and the other has an inwardly concave groove 112 on its circumferential surface. As the inner plug 2 moves, the protrusion 211 can be inserted into or slide out of the groove 112, thereby realizing a detachable connection between the inner plug 2 and the outer cover 1. The protrusions 211 and the grooves 112 are arranged in a one-to-one correspondence, and the number of the protrusions 211 is not less than two, and similarly, the number of the grooves 112 is not less than two, thereby improving the stability and reliability of the connection and fixation of the inner plug 2.

[0064] In one embodiment, a slide groove 111 is provided on the hole wall of the connecting hole 11, and the slide groove 111 extends along the axial direction of the outer cover 1. A clamping groove 112 is provided on one side of the slide groove 111 along the circumference of the outer cover 1; a clamping protrusion 211 is provided on the outer periphery of the connecting column 21, and the clamping protrusion 211 is inserted into the slide groove 111, and is screwed into or out of the clamping groove 112 as the inner plug 2 rotates. That is to say, the inner plug 2 is installed into the outer cover 1 in an axial sliding manner and is fixed to the outer cover 1 in a circumferential rotation manner at a smaller angle. The installation and disassembly of the inner plug 2 are simple and labor-saving, which further improves the convenience of disassembly and cleaning of the cup cover 01. On the one hand, the cam 211 cooperates with the slide groove 111 to form circumferential positioning and axial guidance between the inner plug 2 and the outer cover 1, thereby increasing the stability of the inner plug 2 during installation, preventing the inner plug 2 and the outer cover 1 from rotating relative to each other, affecting the normal cooperation between the cam 211 and the slot 112, and further affecting the installation and removal of the inner plug 2; on the other hand, the slot 112 and the slide groove 111 are interconnected, and the cam 211 is screwed into the slot 112 from the slide groove 111, avoiding interference between the cam 211 and other parts, reducing the deformation or avoidance requirements of the cam 211, so that the cam 211 can adopt a rigid structure, and the cam 211 and the slot 112 can form a rigid fit, thereby increasing the reliability of the connection of the inner plug 2. It can be understood that in other embodiments, the cam 211 can also be set as an elastic structure, and the cam 211 is elastically deformed to be inserted into or slide out of the slot 112.

[0065] Furthermore, a locking portion 41 is provided below the button 4, and the locking portion 41 is provided between the card slot 112 and the slide slot 111. The locking portion 41 stops the card protrusion 211 or avoids the card protrusion 211 as the button 4 moves, and locks the inner plug 2 by stopping the card protrusion 211, and releases the inner plug 2 by avoiding the card protrusion 211. The structure is simple, the action is simple and efficient, and the coordination or connection between the locking portion 41 and other components can be reduced, thereby simplifying the overall structure of the cup cover 01 and reducing the production cost. Among them, the locking portion 41 can be provided only between one group of card slots 112 and the slide slot 111, and the locking portion 41 can also be provided for each group of card slots 112 and the slide slot 111.

[0066] Specifically, when at least a portion of the locking portion 41 is located within the movement path of the latch protrusion 211, the locking portion 41 stops the latch protrusion 211. At this time, the locking portion 41 cannot move freely between the latch slot 112 and the slide slot 111, thereby preventing the latch protrusion 211 from escaping from the latch slot 112 during use, causing the inner plug 2 to accidentally loosen or fall off; when the locking portion 41 completely moves out of the movement path of the latch protrusion 211, the locking portion 41 avoids the latch protrusion 211. At this time, the locking portion 41 can move freely between the latch slot 112 and the slide slot 111, thereby realizing the installation and disassembly of the inner plug 2.

[0067] Furthermore, a guide surface 411 is provided at the top of the locking portion 41, and the height of the guide surface 411 gradually increases along the direction away from the slide groove 111. For example, the guide surface 411 may be an inclined surface or an arc surface. When the protrusion 211 is screwed from the slide groove 111 into the slot 112, the protrusion 211 and the guide surface 411 abut against each other, and the guide surface 411 converts the circumferential movement of the protrusion 211 into the axial movement of the locking portion 41, thereby forcing the locking portion 41 to automatically avoid the protrusion 211. In other words, when the inner plug 2 is installed, there is no need to manually operate the button 4 to avoid the protrusion 211, which further simplifies the installation operation of the inner plug 2 and improves the use experience of the cup cover 01. In addition, when the protrusion 211 is screwed from the slot 112 into the slide groove 111, it is only necessary to rotate the inner plug 2 so that the protrusion 211 is above the guide surface 411, and the protrusion 211 can slide freely along the guide surface 411 and fall, which further simplifies the disassembly operation of the inner plug 2.

[0068] Furthermore, a guide groove 113 is provided at a position of the outer cover 1 directly opposite to the locking portion 41, and the guide groove 113 extends along the axial direction of the outer cover 1; at least a portion of the locking portion 41 is inserted into the guide groove 113 and slides along the guide groove 113, and the locking portion 41 is supported and reinforced by the guide groove 113 to prevent the locking portion 41 from being damaged such as displacement or deformation, thereby ensuring that the button 4 can reliably lock the inner plug 2.

[0069] Furthermore, a connecting groove 114 is provided between the card slot 112 and the slide slot 111, and the card protrusion 211 is screwed into or out of the card slot 112 along the connecting groove 114. The connecting groove 114 is higher than the card slot 112 to form a stop step 115, so as to increase the difficulty of the card protrusion 211 to be separated from the card slot 112, and play a double insurance role, that is, even if the button 4 fails unexpectedly and releases the inner plug 2, under the action of the stop step 115, the card protrusion 211 is difficult to be screwed out of the card slot 112, thereby effectively reducing the possibility of the inner plug 2 loosening or falling off during use. Among them, the connecting groove 114 can be provided only between one group of card slots 112 and the slide slot 111, or the connecting groove 114 can be provided for each group of card slots 112 and the slide slot 111.

[0070] Furthermore, an elastic member 12 (for example, a spring or rubber, etc.) can be provided between the outer cover 1 and the inner cover. The elastic member 12 expands and contracts along the axial direction of the outer cover 1. The two ends of the elastic member 12 elastically press against the outer cover 1 and the inner cover respectively to force the inner cover and the outer cover 1 to move away from each other, thereby ensuring that the latching protrusion 211 can be stably supported on the bottom surface of the latching groove 112, thereby preventing the latching protrusion 211 from being suspended in the air and affecting the stability of the inner plug 2.

[0071] In one embodiment, the elastic member 12 is disposed inside the outer cover 1, and one end of the elastic member 12 passes through the outer cover 1 and abuts against the upper surface of the inner plug 2. On the one hand, the elastic member 12 is located inside the outer cover 1, and the elastic member 12 will not fall off during the disassembly of the inner plug 2, which can reduce the number of parts to be disassembled and assembled when the cup cover 01 is cleaned, improve the convenience of cleaning the cup cover 01, and prevent the elastic member 12 from popping out or falling off during the disassembly of the inner plug 2, resulting in missing parts, and effectively extend the service life of the cup cover 01. On the other hand, under the action of the elastic member 12, the cover body 1a and the outer cover 1 have a tendency to separate from each other, which can push the inner plug 2 downward during the disassembly of the inner plug 2, making the disassembly of the inner plug 2 more convenient and labor-saving, and can push the outer cover 1 upward during the opening of the cup cover 01, making the opening operation more convenient and labor-saving.

[0072] Specifically, the outer cover 1 includes a cover body 1a and an outer cover 1b that are connected to each other. The outer cover 1b can be fixedly connected to the cover body 1a by any appropriate method such as bonding, snapping or threading. In other words, the outer cover 1 is formed by combining two parts, which can not only facilitate the assembly of parts inside the outer cover 1, but also enable the cup cover 01 to form a neat and smooth external shape, thereby improving the integrity and appearance of the cup cover 01. The elastic member 12 is installed between the cover body 1a and the outer cover 1b, and one end of the elastic member 12 passes through the through hole set in the cover body 1a and is exposed; a limiting structure can be set between the elastic member 12 and the cover body 1a to prevent the elastic member 12 from completely passing through the through hole and falling off.

[0073] Furthermore, the outer cover 1 is provided with an active buckle 13, which can be arranged inside the outer cover 1, and a part of the active buckle 13 passes through the side wall of the outer cover 1 and is exposed, and the active buckle 13 is used to connect the cup body 02; the active buckle 13 and the button 4 are pressed against each other, and the button 4 drives the active buckle 13 to realize buckling or disengagement. As long as the user applies external force to the button 4 to move the button 4 along the axial direction of the outer cover 1, the active buckle 13 can be controlled to open the cup cover 01, and the cover opening operation is convenient, which improves the user experience. There are multiple active buckles 13, and each active buckle 13 is spaced around the axis of the outer cover 1 to increase the reliability and stability of the connection and fixation between the cup cover 01 and the cup body 02.

[0074] In one embodiment, the middle part of the movable buckle 13 is rotatably connected to the outer cover 1, and the movable buckle 13 can swing back and forth in a vertical plane; a part of the movable buckle 13 extends radially along the outer cover 1 and is connected to the button 4; another part of the movable buckle 13 extends axially along the outer cover 1 and is formed with a claw 131, which passes through the side wall of the outer cover 1 and is exposed, and the button 4 drives the claw 131 to open (disengage the buckle) or clamp (achieve the buckle). The button 4 acts on the movable buckle 13 through the principle of leverage, converting the axial movement of the button 4 into the rotation of the movable buckle 13. The overall layout is more flexible and compact, improving space utilization, thereby reducing the overall volume of the cup cover 01. It can be understood that in other embodiments, the movable buckle 13 can also be slidably connected to the outer cover 1.

[0075] Furthermore, when the movable buckle 13 is rotatably connected to the outer cover 1, two adjacent movable buckles 13 can be interconnected through the strip structure 132, so that the movable buckles 13 are interconnected to form an annular whole, further reducing the number of parts and simplifying the assembly operation of the cup cover 01.

[0076] Furthermore, a vent hole 22 is provided at the center of the inner plug 2 (i.e., the center of the connecting column 21), and a vent seal ring 23 is installed at the vent hole 22; a vent rod 42 is provided below the button 4, and the vent rod 42 cooperates with the vent seal ring 23 to open or close the vent hole 22, which can meet both the sealing requirements of the liquid and the venting requirements of opening the lid. Specifically, in a natural state, the vent rod 42 and the vent seal ring 23 form a seal, and the vent hole 22 is closed to prevent the liquid in the cup from leaking; when the user applies an external force to the button 4, and the button 4 moves along the axial direction of the outer cover 1, a gap is formed between the vent rod 42 and the vent seal ring 23, and the vent hole 22 is opened, thereby avoiding the formation of a negative pressure state in the cup body 02, making the opening of the cup cover 01 more labor-saving.

[0077] In addition, an embodiment of the present application also provides a water cup, which includes a cup body 02 and any cup cover 01 provided in the embodiment of the present application. The cup cover 01 is detachably connected to the cup body 02. For example, the cup cover 01 can be connected to the cup body 02 in any appropriate manner such as a threaded manner or a snap-on manner.

[0078] The above description is only the preferred embodiment of the present application and is not intended to limit the present application. For those skilled in the art, the present application may have various modifications and variations. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the present application shall be included in the protection scope of the present application.
