UTILITY MODEL CONTENTS

[0003] Therefore, the utility model aims at providing a cup cover assembly and a water cup to at least solve one of the problems in the prior art or related art.

[0004] The first aspect embodiment of the utility model provides a cup cover assembly, which comprises a bottom cover, a side wall of the bottom cover is provided with a groove, and a drinking water port is arranged in the bottom cover; a flip cover is hingedly connected with the bottom cover; a button assembly can lock the flip cover relative to the bottom cover when the flip cover is in a closed state, the button assembly comprises an inner button and a lock key, the inner button is movably arranged in the groove; the lock key is slidably connected with the bottom cover, in the radial direction of the bottom cover, the lock key is arranged outside the inner button, sliding the lock key can unlock or lock the button assembly, when the button assembly is in an unlocked state, pressing the lock key can drive the inner button to move to open the flip cover.

[0005] The cup cover assembly provided in the aspect embodiment is characterized in that the lock key is arranged outside the inner button in the radial direction of the bottom cover, sliding the lock key can unlock and lock the inner button, when the lock key is in an unlocked position, pressing the lock key can drive the inner button to move in the groove and separate the flip cover from the bottom cover, that is, sliding and pressing the lock key can open the flip cover, and sliding the lock key can lock the flip cover after the flip cover is closed. The cup cover assembly provided in the aspect embodiment has the functions of locking the key and secondary opening, and the lock key and the inner button are arranged at the same position of the cup cover assembly, so that the flip cover can be opened only by sliding and pressing the lock key, the action continuity is good, no secondary operation is needed, one-hand unlocking and opening the flip cover can be realized at one time, the lock key can be locked only by sliding the lock key after the flip cover is closed, the operation is convenient, and the convenience of use is greatly improved.

[0006] In some embodiments, the groove extends along the radial direction of the bottom cover, and the inner button is capable of sliding in the groove along the radial direction of the bottom cover; the lock key is capable of sliding along the circumferential direction and / or the axial direction of the bottom cover, and is capable of being aligned with or offset from the inner button to unlock or lock the button assembly. In this way, when the lock key is in the unlocked state, pressing the lock key can drive the inner button to slide in the groove towards the central axis of the bottom cover, so that the inner button releases the locking of the flip cover and the flip cover can be opened; in the process of unlocking and locking the button assembly, the lock key slides along the circumferential direction of the bottom cover, that is, the lock key slides left and right; or, the lock key slides along the axial direction of the bottom cover, that is, the lock key slides up and down, so as to move to a position opposite to the inner button or a position staggered with the inner button; in addition, the lock key can also slide obliquely, such as reciprocating between the upper left and the lower right, or reciprocating between the upper right and the lower left, to unlock or lock the lock key.

[0007] In some embodiments, in the radial direction of the bottom cover, the lock key partially protrudes from the outer side wall of the bottom cover. In this way, part of the structure of the lock key protrudes from the outer side wall of the bottom cover, which facilitates the exertion of force by the hand when the lock key slides in the unlocked position and the locked position.

[0008] In some embodiments, the bottom cover comprises a bottom cover body and a lock key fixing ring sleeved on the outer periphery of the bottom cover body, the groove is arranged on the bottom cover body, the lock key fixing ring is provided with a notch at a position corresponding to the groove, and the lock key is movably arranged in the notch. The side wall of the notch can abut against the lock key to limit the sliding of the lock key. In this way, during the sliding of the lock key in the notch, the lock key cannot continue to slide when it abuts against the side wall of the notch, which is the maximum stroke of the lock key, and the side wall of the notch can limit the sliding of the lock key to prevent the lock key from sliding beyond the predetermined range.

[0009] In some embodiments, the length direction of the notch is arranged along the circumferential direction of the lock key fixing ring, and the lock key is capable of sliding along the length direction of the notch. In this way, the lock key slides along the circumferential direction of the lock key fixing ring, that is, the lock key can slide left and right in the notch, and the distance in the circumferential direction of the lock key fixing ring is long, so that the sliding path of the lock key can be long, which is beneficial to the structural arrangement of the lock key.

[0010] In some embodiments, part of the structure of the lock key is clamped between the bottom cover and the lock key fixing ring, two positioning portions are arranged on the side of the lock key fixing ring in contact with the lock key, and a limiting portion is arranged on the side of the lock key in contact with the lock key fixing ring. One of the positioning portions cooperates with the limiting portion when the lock key slides to the locked position, and the other positioning portion cooperates with the limiting portion when the lock key slides to the unlocked position.

[0011] In the embodiments, the two positioning portions include a first positioning portion and a second positioning portion, and the limiting portion can cooperate with the first positioning portion and the second positioning portion during the sliding of the lock key. The position where the limiting portion abuts against the first positioning portion is the unlocking position, and the position where the limiting portion abuts against the second positioning portion is the locking position.

[0012] In some embodiments, one of the positioning portion and the limiting portion is a protrusion, and the other is a recess. When the lock key slides to the locking position and the unlocking position, the protrusion is located in the recess. In this way, the sliding of the protrusion into the recess produces a "click" sound, thereby playing a prompting role through sound when the lock key slides to the locking position and the unlocking position, and the user can know that the lock key has slid to the specified position in time, avoiding the sliding of the lock key out of range.

[0013] In some embodiments, a limiting rib is arranged on the outer side wall of the inner key, the limiting rib protrudes outward in the radial direction, and an abutting portion is arranged on the bottom cover at a position outside the limiting rib. The limiting rib can abut against the abutting portion to limit the position of the inner key. In this way, the contact between the limiting rib on the inner key and the abutting portion can limit the inner key to stay at the same position when it is reset under the action of the elastic portion after being closed, thereby ensuring the stability of repeated opening and closing of the inner key.

[0014] In some embodiments, the abutting portion is formed by a structure of the lock key fixing ring located below the notch. In this way, the notch penetrates the lock key fixing ring upwardly, and the notch does not penetrate the lock key fixing ring downwardly. The structure of the lock key fixing ring located below the notch forms the abutting portion. Since the lock key fixing ring is assembled to the bottom cover body later, it does not affect the assembly of the inner key and other structures into the groove. The formation of the abutting portion is beneficial to the assembly of the product.

[0015] In some embodiments, the inner key includes a key portion and an elastic portion. A first end of the elastic portion abuts against the inner side wall of the groove, and a second end of the elastic portion abuts against the key portion, so that the inner key can be reset after being pressed. The lower end of the flip cover extends downwardly to form a plug-in portion. The plug-in portion can be inserted into the lock key and the key portion, and can be clamped with the key portion to lock the flip cover.

[0016] In the embodiments, when the flip cover is buckled with the bottom cover, the inner key can be buckled and connected with the flip cover, so that the flip cover and the bottom cover are buckled and connected. After the lock key is unlocked, the lock key is pressed to drive the inner key to move in the direction of the central axis of the bottom cover, so that the inner key is separated from the plug-in portion, the flip cover is separated from the bottom cover, and the flip cover is opened.

[0017] In some embodiments, the lock key is provided with a protruding clamping point on the side wall facing the inner key, and the outer side wall of the insertion part is formed with a recess capable of clamping the clamping point; in the case of pressing the key assembly to release the flip cover, the flip cover rotates upward around the hinge shaft, the clamping point is clamped with the recess to make the flip cover open relative to the bottom cover by a first preset angle; the key assembly is released when the flip cover is opened relative to the bottom cover by the first preset angle, and the lock key moves away from the central axis of the bottom cover under the action of the elastic part, so that the clamping point is separated from the recess, and the flip cover can be opened relative to the bottom cover by a second preset angle.

[0018] In these embodiments, when the lock key is unlocked, pressing the lock key can drive the inner key to move towards the central axis of the bottom cover, and the flip cover can be opened. When the flip cover is opened by the first preset angle, the clamping point abuts against the recess, so that the valve cover is clamped at the angle and cannot be completely opened at one time. The first step of opening by the first preset angle can realize gas exchange between the water cup and the outside, so that the pressure inside and outside the water cup is balanced. After the lock key is released, the inner key and the lock key are driven to move away from the central axis of the bottom cover by the elastic force of the elastic part until they return to the initial position before being pressed. With the movement of the lock key, the clamping point provided on the lock key is separated from the recess provided on the flip cover, and the flip cover can be opened relative to the bottom cover by a second preset angle. The second step of opening by the second preset angle can make the flip cover completely open, and the drinking opening is exposed.

[0019] In some embodiments, the bottom cover is provided with a stop portion, which can block the movement of the lock key in the radial direction of the bottom cover towards the central axis of the bottom cover when the lock key moves to the locking position. In this way, when the lock key is in the locking position, the stop portion can limit the movement of the lock key towards the central axis of the bottom cover, i.e. the lock key cannot be pressed inward, and the inner key cannot be pressed inward.

[0020] The second aspect embodiment of the utility model provides a water cup, the water cup includes a cup body and a cup cover assembly of any one of the above embodiments, and the cup cover assembly is combined on the cup body.

[0021] The water cup provided by the embodiments of the present aspect has the cup cover assembly of any one of the above embodiments, and thus has the beneficial effects of any one of the above embodiments, which will not be repeated here.

[0047] In the cup cover assembly of the related art, a lock key for unlocking and a button for opening the flip cover are generally included, and the lock key is usually separately placed at a certain distance from the side edge of the button. When opening the cover, the lock key needs to be opened first, and then the button is pressed, or a semicircular ring-shaped lock catch is made around the button, and the flip cover is locked by the lock catch so that it cannot be opened. When opening the cover, the lock catch needs to be turned first and then the button is pressed. Since the lock key and the button are not in the same position, after unlocking, the button is pressed to open the flip cover, which is more troublesome. When closing, the same is true.

[0048] Based on this, the present application proposes a new cup cover assembly that can overcome the above problems. The cup cover assembly and water cup provided by the embodiments of the present application will be introduced below. Figures 1 to 8

[0049] As Figure 1 , Figure 3 , Figure 4 , Figure 5 and Figure 6 ​As shown, the first aspect embodiment of the utility model discloses a cup cover assembly, including bottom cover 10, flap 20 and button assembly, the lateral wall of bottom cover 10 is provided with recess 111, bottom cover 10 is provided with the drinking water mouth 112 that communicates cup body 50 inside, flap 20 is connected with bottom cover 10 articulately, and flap 20 can be connected with bottom cover 10 locking by button assembly, button assembly includes inner button 30 and lock key 40, and inner button 30 is movably arranged in recess 111, lock key 40 is slidably connected with bottom cover 10, in the radial direction of bottom cover 10, lock key 40 is arranged in the outside of inner button 30, and sliding lock key 40 can unlock or lock button assembly, when button assembly is in the unlocking state, press lock key 40 can drive inner button 30 to move to open flap 20.

[0050] The cup cover assembly provided by the aspect embodiment, lock key 40 is arranged in the outside of inner button 30 in the radial direction of bottom cover 10, and sliding lock key 40 can unlock and lock inner button 30, when lock key 40 is located in the unlocking position, press lock key 40 can drive inner button 30, so that inner button 30 is movable in recess 111 and can make flap 20 separate from bottom cover 10, that is, sliding and pressing lock key 40 can open flap 20, after closing flap 20, sliding lock key 40 can realize locking. The cup cover assembly provided by the aspect embodiment, while having the locking key function and secondary opening function, makes lock key 40 and inner button 30 all be in the same position of cup cover assembly, and only sliding and pressing lock key 40 can open flap 20, and the action continuity is good, and secondary operation is not needed, can realize one-hand one-time unlocking and cover opening, after closing flap 20, sliding lock key 40 can realize locking, and the operation is convenient, and the convenience of use is greatly improved.

[0051] In some embodiments, as shown in Figure 5 and Figure 7 Recess 111 extends along the radial direction of bottom cover 10, and inner button 30 can slide in recess 111 along the radial direction of bottom cover 10, as shown in Figure 4 、 Figure 5 and Figure 6As shown, the lock key 40 can slide along the circumferential direction and / or axial direction of the bottom cover 10, so as to move to a position opposite to the inner key 30 or staggered with each other. In this way, when the lock key 40 is in the unlocking state, pressing the lock key 40 can drive the inner key 30 to slide in the groove 111 towards the central axis of the bottom cover 10, so that the inner key 30 releases the locking of the flip cover 20 and the flip cover 20 can be opened; in the process of unlocking and locking the key assembly, the lock key 40 slides along the circumferential direction of the bottom cover 10, that is, the lock key 40 slides left and right; or, the lock key 40 slides along the axial direction of the bottom cover 10, that is, the lock key 40 slides up and down; in addition, the lock key 40 can also slide obliquely, such as reciprocating between the upper left and the lower right, or reciprocating between the upper right and the lower left, so as to unlock or lock the lock key 40.

[0052] In order to facilitate the sliding and pressing of the lock key 40, in some embodiments, as shown in Figure 1 , Figure 2 and Figure 3 , in the radial direction of the bottom cover 10, the lock key 40 partially protrudes from the outer side wall of the bottom cover 10. In this way, the part of the structure of the lock key 40 protrudes from the outer side wall of the bottom cover 10, which is more conducive to the force exerted by the hand when pushing the lock key 40 to slide between the unlocking position and the locking position.

[0053] In some embodiments, as shown in Figure 1 , Figure 2 , Figure 3 , Figure 4 , Figure 5 , Figure 6 and Figure 8 , the bottom cover 10 comprises a bottom cover body 110 and a lock key fixing ring 120 sleeved on the outer periphery of the bottom cover body 110, the groove 111 is arranged on one side of the bottom cover body 110 in the circumferential direction, the lock key fixing ring 120 is provided with a notch 121 at a position corresponding to the groove 111, and the lock key 40 is movably arranged in the notch 121. The side wall of the notch 121 can abut against the lock key 40 to limit the sliding of the lock key 40. In this way, during the sliding of the lock key 40 in the notch 121, the lock key 40 cannot continue to slide when it abuts against the side wall of the notch 121, which is the maximum stroke of the lock key 40. The side wall of the notch 121 can limit the sliding of the lock key 40 to prevent the lock key 40 from sliding beyond the predetermined range.

[0054] It can be understood that the side walls on both sides of the notch 121 can abut against the lock key 40 to limit the sliding of the lock key 40.

[0055] For the specific arrangement of the notch 121, as shown in Figure 4 , Figure 5 , Figure 6 andFigure 8 As shown in some embodiments, the length direction of the gap 121 is arranged along the circumferential direction of the lock key fixing ring 120, and the lock key 40 can slide along the length direction of the gap 121. In this way, the lock key 40 slides along the circumferential direction of the lock key fixing ring 120, that is, the lock key 40 can slide left and right in the gap 121, the distance in the circumferential direction of the lock key fixing ring 120 is long, and the sliding path of the lock key 40 can be long, which is beneficial to the structural arrangement of the lock key 40.

[0056] In some embodiments, as Figure 5 As shown, a part of the structure of the lock key 40 is clamped between the bottom cover 10 and the lock key fixing ring 120, two positioning portions 122 are arranged on the surface of the lock key fixing ring 120 in contact with the lock key 40, and a limiting portion 410 is arranged on the surface of the lock key 40 in contact with the lock key fixing ring 120. One of the positioning portions 122 is in contact with the limiting portion 410 when the lock key 40 slides to the locking position, and the other positioning portion 122 cooperates with the limiting portion 410 when the lock key 40 slides to the unlocking position.

[0057] In these embodiments, the two positioning portions 122 include a first positioning portion 122a and a second positioning portion 122b, both of which are formed as pits, and the limiting portion 410 is a protrusion formed on the outer edge of the lock key 40. During the sliding of the lock key 40, the limiting portion 410 can be respectively slid to face and be inserted into the first positioning portion 122a and the second positioning portion 122b. The position where the limiting portion 410 faces the second positioning portion 122b is the unlocking position, and the position where the limiting portion 410 faces the first positioning portion 122a is the locking position.

[0058] It can be understood that the locking position is the position of the lock key 40 when the key assembly is in the locked state, and the unlocking position is the position of the lock key 40 when the key assembly is in the unlocked state.

[0059] In some embodiments, as Figure 5 As shown, one of the positioning portion 122 and the limiting portion 410 is a protrusion, and the other is a pit. When the lock key 40 slides to the locking position and the unlocking position, the protrusion is located in the pit. In this way, the sliding of the protrusion into the pit produces a "click" sound, thereby playing a prompting role through sound when the lock key 40 slides to the unlocking position and the locking position, and the lock key 40 can be known to have been slid to the specified position in time, avoiding the sliding of the lock key 40 out of range.

[0060] In some embodiments, as an example, two positioning portions 122 are optionally arranged on the inner surface area of the left or right side of the gap 121 of the lock key fixing ring 120, and a limiting portion 410 is arranged on the outer side wall of the lock key 40. In the present application Figure 5 , the two positioning portions 122 are arranged on the left side of the gap 121 of the lock key fixing ring 120.

[0061] It can be understood that the cooperation of the side wall of the gap 121 and the lock key 40 forms a secondary limiting on the basis of the positioning portion 122 and the limiting portion 410, which can further avoid the sliding of the lock key 40 beyond the predetermined range.

[0062] It is worth noting that in other embodiments, the specific structure of the positioning portion 122 and the limiting portion 410, the positioning portion 122 can also be a protruding rib, and the limiting portion 410 can also be a protruding point or other protruding structure. Specifically, two protruding ribs are arranged on the side of the lock key fixing ring 120 in contact with the lock key 40, and a protruding point is arranged on the side of the lock key 40 in contact with the lock key fixing ring 120. The two protruding ribs include a first protruding rib and a second protruding rib. During the sliding of the lock key 40, the protruding point can abut against the first protruding rib and the second protruding rib. The position where the protruding point abuts against the first protruding rib is the unlocking position, and the position where the protruding point abuts against the second protruding rib is the locking position. Of course, the present solution is not limited to this, and specific cases will not be enumerated one by one here, but all fall within the protection scope of the present solution without departing from the design concept.

[0063] In some embodiments, as shown in Figure 1 , Figure 3 and Figure 8 , a limiting rib 311 is arranged on the outer side wall of the inner key 30, the limiting rib 311 protrudes outwardly in the radial direction, and an abutting portion 123 is arranged on the bottom cover 10 at the position outside the periphery of the limiting rib 311. The limiting rib 311 can abut against the abutting portion 123 to limit the position of the inner key 30. In this way, the contact between the limiting rib 311 on the inner key 30 and the abutting portion 123 can prevent the inner key 30 from being bounced out under the elastic force of the elastic portion 320, and can ensure that the inner key 30 and the lock key 40 maintain a gap and ensure smooth sliding of the lock key 40.

[0064] For the specific structure of the abutting portion 123, in some embodiments, the abutting portion 123 is formed by the structure of the lock key fixing ring 120 below the notch 121. In this way, the notch 121 penetrates the lock key fixing ring 120 upwardly, the notch 121 does not penetrate the lock key fixing ring 120 downwardly, and the structure of the lock key fixing ring 120 below the notch 121 forms the abutting portion 123. Since the lock key fixing ring 120 is assembled to the bottom cover body 110 later, it does not affect the assembly of the inner key 30 and other structures into the groove 111, and it is also beneficial for the assembly of the product while forming the abutting portion 123.

[0065] It should be noted that the abutting portion 123 can also be a protruding structure arranged on the bottom cover body 110 and located outside the groove 111, which can also play a role in stopping the limiting rib 311. Of course, the present solution is not limited thereto, and specific cases will not be enumerated one by one here, but all fall within the protection scope of the present solution without departing from the design concept.

[0066] In some embodiments, the inner key 30 includes a key portion 310 and an elastic portion 320, a first end of the elastic portion 320 abuts against the inner side wall of the groove 111, and a second end of the elastic portion 320 abuts against the key portion 310, so that the inner key 30 after being subjected to pressure can be reset; the lock key 40 is provided with a protruding clamping point 420 on the side wall facing the inner key 30, the lower end of the flip cover 20 extends downwardly to form a plug-in portion 220, and the outer side wall of the plug-in portion 220 is formed with a recessed portion 221 capable of clamping the clamping point 420; for the opening process of the flip cover 20 and the bottom cover 10, as shown in Figure 2 , in the case of pressing the key assembly to separate the clamping structure of the flip cover 20 and the bottom cover 10, the flip cover 20 rotates upwardly around the hinge shaft 210, the clamping point 420 clamps the recessed portion 221 to make the flip cover 20 open relative to the bottom cover 10 by a first preset angle; as shown in Figure 3 , in the case of releasing the key assembly when the flip cover 20 is opened relative to the bottom cover 10 by the first preset angle, the lock key 40 moves away from the center axis of the bottom cover 10 under the action of the elastic portion 320, so that the clamping point 420 is separated from the recessed portion 221, and the flip cover 20 can be opened relative to the bottom cover 10 by a second preset angle.

[0067] In the embodiments, when the lock key 40 is unlocked, pressing the lock key 40 can drive the inner button 30 to move towards the direction of the central axis of the bottom cover 10, and the flip cover 20 can be opened. When the first preset angle is opened, the clamping point 420 is in abutment with the recessed part 221, so that the flip cover 20 is clamped at the angle and cannot be opened completely at one time. The first step of opening the first preset angle can realize the gas exchange between the water cup and the outside, so as to balance the pressure inside and outside the water cup. After the lock key 40 is released, under the action of the elastic part 320, the inner button 30 and the lock key 40 are driven by the elastic force of the elastic part 320 to move away from the central axis of the bottom cover 10 until they return to the initial position before being pressed. With the movement of the lock key 40, the clamping point 420 arranged on the lock key 40 is separated from the recessed part 221 arranged on the flip cover 20, and the flip cover 20 can be opened at a second preset angle relative to the bottom cover 10. The second step of opening the second preset angle can make the flip cover 20 completely open, and the drinking opening 112 is exposed.

[0069] In some embodiments, as an example, optionally, the flip cover 20 and the bottom cover 10 are connected through the hinge shaft 210 and the hinge torsional spring 211. After the clamping point 420 is separated from the recessed part 221, the flip cover 20 can be opened to realize complete opening under the action of the hinge torsional spring 211. That is, the second preset angle is the angle between the flip cover 20 and the bottom cover 10 when they are completely opened. Further, as shown in Figure 3 , the range of the second preset angle is 150° to 260°. On the one hand, this range does not affect the user to drink water, and on the other hand, it can also avoid that the opening angle is too large to cause the flip cover 20 and the bottom cover 10 to be in contact, which is difficult to realize in structure.

[0070] In some embodiments, as shown in Figure 7 , the bottom cover 10 is provided with a stop part 113. When the lock key 40 moves to the locking position, the stop part 113 can block the movement of the lock key 40 in the radial direction of the bottom cover 10 towards the central axis of the bottom cover 10. In this way, when the lock key 40 is in the locking position, the stop part 113 can limit the movement of the lock key 40 towards the central axis of the bottom cover 10, that is, the lock key 40 cannot be pressed inward, and the inner button 30 cannot be pressed inward.
