[0002] Liquid containers such as water cups, kettles, and tea cups are widely used in people's daily lives. However, when carrying outside, putting them in backpacks, or when children are not under adult supervision, the container lids of liquid containers are easily opened by mistake, causing the liquid inside to spill randomly, damaging other items or causing scalding, resulting in low safety of liquid containers. Utility Model Content

[0003] In view of this, the present application provides a container cover and a liquid container to solve the technical problem in the prior art that the container cover is easily opened by mistake.

[0004] In a first aspect, an embodiment of the present application provides a container cover, comprising: a first cover body, the first cover body being provided with a slot; a second cover body, the second cover body being sleeved on the outer side of the first cover body, and the first cover body and the second cover body being rotatably connected, and the second cover body having a first top wall; a limiting member, the limiting member having a clamping portion, and the limiting member being movably connected to the first top wall so that the clamping portion and the clamping slot can be clamped or unclamped; when the clamping portion and the clamping slot are clamped, the first cover body and the second cover body can be restricted from rotating relative to each other, and when the clamping portion and the clamping slot are unclamped, the first cover body and the second cover body can rotate relative to each other.

[0005] In this embodiment, a limiting member having a clamping portion and a first cover body having a clamping slot are provided, so that the clamping portion and the clamping slot are clamped and matched to realize the connection between the first cover body and the limiting member, thereby realizing the connection between the first cover body and the second cover body. When the clamping portion of the limiting member is clamped with the clamping slot, the relative rotation of the first cover body and the second cover body can be restricted, that is, when the second cover body is rotated, the first cover body can be driven to rotate synchronously, so that when the second cover body is rotated, the first cover body can be rotated relative to the container body, so that the first cover body is connected or disconnected from the container body; when the clamping portion of the limiting member is disconnected from the clamping slot, the first cover body and the second cover body can be relatively rotated, that is, when the second cover body is rotated, the first cover body does not rotate, so that when the second cover body is rotated, the first cover body cannot rotate relative to the container body, and the cover cannot be opened. By providing a limiter that is movably connected to the first top wall of the second cover body, the user can adjust whether the clamping part of the limiter is clamped with the clamping slot as needed to adjust the state of the container cover. When the cover does not need to be opened, the limiter is released from the clamping slot to avoid the container cover being opened by mistake during carrying or use, thereby improving the safety of the container cover. The limiter is located on the first top wall of the second cover body, which is convenient for the user to operate the limiter to move relative to the second cover body, so that the clamping part and the clamping slot can be easily switched to be clamped or released.

[0006] In a specific embodiment, the container cover further comprises a third cover movably connected to the second cover, the third cover can be covered on the second cover, or the second cover can be opened. The third cover has a pressing portion, and the pressing portion is used to press the limiting member when the third cover is covered on the second cover, so that the clamping portion and the clamping slot are released from the clamping connection.

[0007] In this embodiment, the third cover body is movably connected to the second cover body, so that the third cover body can move relative to the second cover body, so that the third cover body covers the second cover body, or opens the second cover body, and when the third cover body covers the second cover body, the limiter movably connected to the top wall of the third cover body can be hidden in the space between the third cover body and the second cover body, so as to protect the limiter, and further prevent the risk of accidentally touching the limiter when it is exposed, resulting in the state switching of the container cover. The third cover body can drive the pressing part to move relative to the second cover body during the movement relative to the second cover body, so that the pressing part can press the driving part of the limiter to drive the clamping part to engage or release the clamping groove. Therefore, in this embodiment, the third cover body can not only be used to protect the second cover body, the first cover body and the limiter, but also can be used to drive the limiter to move, so as to realize the switching of the container cover between the first state and the second state.

[0008] In a specific embodiment, the limiting member includes a first rotating shaft, the limiting member is rotatably connected to the second cover body via the first rotating shaft, and the limiting member also includes a driving portion arranged opposite to the clamping portion, and the driving portion and the clamping portion are located on both sides of the first rotating shaft.

[0009] In this embodiment, the limiter includes a driving part and a clamping part located on both sides of the first rotating shaft, so that the driving part can drive the clamping part to rotate around the first rotating shaft, so that the clamping part is clamped or released from the clamping slot. When the driving part is pressed to move the driving part toward the first top wall of the second cover body, the clamping part rotates around the first rotating shaft away from the clamping slot under the drive of the driving part, so that the clamping part is released from the clamping slot, and the container cover is in the second state; when the driving part is lifted to move the driving part away from the first top wall of the second cover body, the clamping part rotates around the first rotating shaft toward the clamping slot under the drive of the driving part, so that the clamping part is clamped with the clamping slot, and the container cover is in the first state. In this embodiment, by setting the driving part and the clamping part at both ends of the first rotating shaft, the user can change the state of the container cover by pressing or lifting the driving part, thereby improving the convenience of operation.

[0010] In a specific embodiment, the cross-sectional area of ​​the clamping portion is larger than the cross-sectional area of ​​the driving portion.

[0011] In this embodiment, when the container cover is in the first state, the clamping part is clamped with the clamping slot, so that the cross-sectional area of ​​the clamping part is larger, which can improve the reliability of the clamping part and the clamping slot, thereby improving the stability when the second cover body drives the first cover body to rotate synchronously, and can extend the service life of the clamping part. At the same time, the cross-sectional area of ​​the driving part is smaller, reducing the space of the container cover occupied by the driving part.

[0012] In a specific embodiment, the limiting member also includes a transition portion of a bending structure, the transition portion connects the clamping portion and the driving portion, and the transition portion is rotatably connected to the first rotating shaft; the distance between the first rotating shaft and the clamping portion is greater than the distance between the first rotating shaft and the driving portion.

[0013] In this embodiment, the driving part and the clamping part of the limiter rotate around the first rotating shaft to form a lever structure, in which the driving part is a power arm and the clamping part is a resistance arm, so that the distance between the first rotating shaft and the driving part is greater than the distance between the first rotating shaft and the clamping part, so that the length of the power arm in the lever structure is greater than the length of the resistance arm, so that it is a labor-saving lever structure. At the same time, when the distance between the first rotating shaft and the driving part is greater than the distance between the first rotating shaft and the clamping part, the smaller stroke of the driving part can also achieve a larger stroke of the clamping part, so that the user can save more effort when pressing the driving part to drive the clamping part to rotate around the first rotating shaft, thereby improving the use experience. In this embodiment, the driving part and the clamping part are connected by a transition part of a bending structure, so that the driving part and the clamping part form a height difference in the height direction of the container cover, so that in the process of switching the state of the container cover, the clamping part does not need to rotate too much around the first rotating shaft to achieve or release the clamping with the card slot, thereby reducing the space required for the rotation of the clamping part to reduce the overall size of the container cover.

[0014] In a specific embodiment, the container cover further includes a first elastic member, and the first elastic member is elastically connected to the driving part.

[0015] In this embodiment, when the driving part is pressed, the driving part moves toward the direction of the first top wall of the second cover body, so that the container cover is in the second state, and the first elastic member is compressed during this process. When the driving part is released, the driving part can rotate around the first rotation axis away from the first top wall of the second cover body under the action of the rebound force of the first elastic member, so that the clamping part rotates around the first rotation axis toward the clamping groove and clamps therewith, thereby switching the container cover from the second state to the first state. In this embodiment, by providing a first elastic member connected to the driving part, when the driving part is released, the container cover can automatically switch to the first state under the action of the rebound force of the first elastic member, without manual operation, and has the advantages of simple operation and simplified structure.

[0016] In a specific embodiment, the second cover body is further provided with a mounting groove, and the driving part and the first elastic member are located in the mounting groove.

[0017] In this embodiment, the second cover is provided with an installation groove to provide positioning for the installation of the driving part and the first elastic member, and the first elastic member is located in the installation groove, which can prevent the first elastic member from tilting during compression or extension and affecting subsequent use. The installation groove has an opening along the distribution direction of the driving part and the clamping part, so as to facilitate the driving part to move along the installation groove during the rotation of the limiter.

[0018] In a specific embodiment, the first top wall is provided with a slide rail, and the limiting member is slidably connected to the first top wall via the slide rail; along the radial direction of the container cover, the slide rail is connected to the clamping groove.

[0019] In this embodiment, the position-limiting member is slidably connected to the first top wall through the slide rail, which facilitates the adjustment of the position of the position-limiting member, and the slide rail is connected to the card slot along the radial direction of the container cover, so that the position-limiting member can slide through the slide rail to engage or release the card slot, which facilitates the user to change the state of the container cover by sliding the position-limiting member, thereby improving the convenience of operation. Specifically, the position-limiting member can slide along the slide rail to release the card slot, so that the container cover is in the second state; the position-limiting member can also slide along the slide rail to engage with the card slot, so that the container cover is in the first state.

[0020] In a specific embodiment, the limiting member has a connected clamping portion and a driving portion, the clamping portion is located in the slide rail, and the driving portion has a first guide surface, and a preset angle is formed between the first guide surface and the slide rail; the pressing portion has an inclined second guide surface, and when the pressing portion presses the limiting member, the first guide surface abuts against the second guide surface to drive the clamping portion of the limiting member to slide along the slide rail.

[0021] In this embodiment, the stopper has a connected clamping part and a driving part, so that the user can drive the clamping part to slide along the slide rail through the driving part, so that the clamping part is clamped or released from the clamping groove. The driving part has a first guide surface and the pressing part has a second guide surface. When the pressing part moves along the height direction of the container cover to press the stopper, the matching first guide surface and the second guide surface can convert the movement of the pressing part along the height direction of the container cover into the radial movement of the stopper along the container cover, so as to realize driving the clamping part of the stopper to slide radially along the slide rail to switch the state of the container cover.

[0022] In a specific embodiment, the limiting member further has a step portion, the step portion is connected to the driving portion, the slide rail has a second top wall, and along the height direction of the container cover, the second top wall is located between the clamping portion and the step portion.

[0023] In this embodiment, the limiting member has a step portion, and the second top wall of the slide rail is located between the clamping portion and the step portion, which can limit the movement of the limiting member along the height direction of the container cover, avoid the limiting member from falling off during the sliding process, and improve the stability of the limiting member when sliding in the slide rail.

[0024] In a specific embodiment, the container cover further includes a second elastic member, which is installed in the slide rail. Along the radial direction of the container cover, the second elastic member is elastically connected to the clamping portion and the first top wall.

[0025] In this embodiment, when the driving part is pushed, the driving part moves away from the first cover body, thereby driving the engaging part to move away from the slot to release the engaging part from the slot, so that the container cover is in the second state. In this process, the engaging part squeezes the second elastic member, so that the second elastic member is compressed. When the driving part is canceled, the engaging part can move toward the slot to engage with the slot under the action of the rebound force of the second elastic member, so that the container cover switches from the second state to the first state. In this embodiment, by providing a second elastic member elastically connected to the engaging part and the first top wall, when the driving part is canceled, the container cover can automatically switch to the first state under the action of the rebound force of the second elastic member, without manual operation, and has the advantages of simple operation and simplified structure.

[0026] In a specific embodiment, the third cover body is rotatably connected to the second cover body, and the container cover further includes a locking member, which is used to lock the third cover body and the second cover body when the third cover body is covered on the second cover body.

[0027] In this embodiment, when the third cover body covers the second cover body, the two are locked by a locking member. When the user operates the locking member to release the lock between the third cover body and the second cover body, the third cover body can open the second cover body. Therefore, when opening the cover, the user needs to first operate the locking member to release the lock between the third cover body and the second cover body, and then the first cover body and the second cover body can be connected through the clamping portion and the clamping groove, and the cover can be opened only when the second cover body is rotated. This cover opening design can further reduce the risk of erroneous opening caused by accidental touch. In addition, this cover opening design also makes it easy for the user to distinguish the state of the entire container cover through the state of the third cover body.

[0028] In a specific embodiment, the locking member includes a contact end and a first clamping end connected to each other, and the third cover body includes a second clamping end, and the first clamping end is used to release the clamping connection with the second clamping end when the fingerprint recognition of the contact end is passed.

[0029] In this embodiment, the locking member is engaged with the second engaging end of the third cover body through the first engaging end, which can improve the connection reliability. The first engaging end is used to release the engagement with the second engaging end when the fingerprint recognition of the contact end is passed, which improves the safety of use.

[0030] In a specific embodiment, the first cover body has a third top wall, the third top wall is provided with a plurality of the card slots distributed along the circumferential direction, the first top wall has a through hole, and the card slots are located within the projection range of the through hole.

[0031] In this embodiment, the portion of the third top wall provided with the card slot extends out of the second cover body through the through hole, or the portion of the third top wall provided with the card slot is exposed through the through hole, so that the card slot is located within the projection range of the through hole. The through hole of the first top wall can provide positioning for the first cover body and the second cover body when connected, and improve the connection reliability. At the same time, the card slot is located within the projection range of the through hole, which can prevent the first top wall from blocking the card slot and affecting the card connection between the card connection portion and the card slot.

[0032] In a second aspect, an embodiment of the present application provides a liquid container, comprising: a container cover and a container body, wherein the container cover is engaged with the container body; wherein the first cover body is connected to the container body.

[0033] In this embodiment, when the limiting portion of the limiting member is engaged with the card slot, the container cover is in the first state, and the first cover body and the second cover body can rotate synchronously, that is, when the second cover body is rotated, the first cover body can be driven to rotate relative to the container body, so that the first cover body and the container body can be released from the rotational connection, and the container cover is separated from the container body; when the limiting portion of the limiting member is released from the card slot, the container cover is in the second state, and the first cover body and the second cover body can rotate relatively, that is, when the second cover body is rotated, the first cover body cannot be driven to rotate synchronously, and the first cover body and the container body are still in a rotational connection state, so that the container cover cannot be separated from the container body. Therefore, when it is not necessary to open the cover, the limiting portion of the limiting member is released from the card slot, so as to avoid the phenomenon of the container cover being opened by mistake during the carrying or use of the liquid container, thereby improving the safety of the use of the liquid container.

In this embodiment, by providing a limiting member 14 that is movably connected to the first top wall 127 of the second cover body 12, the user can adjust whether the card portion 141 of the limiting member 14 is engaged with the card slot 111 as needed to adjust the state of the container cover 1. When the cover does not need to be opened, the limiting portion 141 of the limiting member 14 is unfastened from the card slot 111, so as to avoid the phenomenon of the container cover 1 being opened by mistake during carrying or use, thereby improving the safety of the container cover 1. The limiting member 14 is located on the first top wall 127 of the second cover body 12 , which is convenient for the user to operate the limiting member 14 to move relative to the second cover body 12 , thereby conveniently switching the engaging portion 141 and the engaging slot 111 to engage or disengage.

[0099] In a specific embodiment, Figure 2 , Figure 3 , Figure 5 and Figure 6 As shown, the first cover body 11 has a third top wall 113, and the third top wall 113 is provided with a plurality of slots 111 distributed along the circumferential direction, and the first top wall 127 of the second cover body 12 has a through hole 122. The portion of the third top wall 113 provided with the slots 111 extends out of the second cover body 12 through the through hole 122, or the portion of the third top wall 113 provided with the slots 111 is exposed through the through hole 122, so that the slots 111 are located within the projection range of the through hole 122. The through hole 122 of the first top wall 127 can provide positioning when the first cover body 11 and the second cover body 12 are connected, and improve the connection reliability. At the same time, the slots 111 are located within the projection range of the through hole 122, so that the first top wall 127 can avoid blocking the slots 111 and affecting the snap-fitting of the snap-fitting portion 141 with the slots 111.

[0101] In this embodiment, when the container cover 1 is in the second state, the engaging portion 141 is released from the engaging slot 111, and the first cover body 11 and the second cover body 12 can rotate relative to each other. The third top wall 113 is provided with a plurality of engaging slots 111 distributed along the circumferential direction, so that when the container cover 1 is switched from the second state to the first state, the engaging portion 141 of the stopper 14 can always correspond to the position of any engaging slot 111, so that the engaging portion 141 can always reengage with any engaging slot 111, so that the first cover body 11 and the second cover body 12 can rotate synchronously, thereby improving the convenience of opening the cover.

[0102] The plurality of card slots 111 may be evenly distributed, and adjacent card slots 111 may be separated by connecting ribs.

[0103] In a specific embodiment, Figure 2 , Figure 3 , Figure 6 and Figure 7 As shown, the limiting member 14 is rotatably connected to the second cover body 12 via a first rotating shaft 143 . The limiting member 14 further includes a driving portion 142 disposed opposite to the clamping portion 141 . The driving portion 142 and the clamping portion 141 are located on both sides of the first rotating shaft 143 .

[0104] In this embodiment, the position limiting member 14 includes a driving portion 142 and a clamping portion 141 located on both sides of the first rotating shaft 143, so that the driving portion 142 can drive the clamping portion 141 to rotate around the first rotating shaft 143, so that the clamping portion 141 is clamped or released from the clamping slot 111. Figure 3 As shown, when the driving portion 142 is pressed to move the driving portion 142 toward the first top wall 127 of the second cover body 12, the engaging portion 141 is driven by the driving portion 142 to rotate around the first rotating shaft 143 away from the engaging slot 111, so that the engaging portion 141 is released from the engaging slot 111, and the container cover 1 is in the second state; Figure 2 As shown, when the driving part 142 is lifted and moved away from the first top wall 127 of the second cover body 12, the engaging part 141 is driven by the driving part 142 to rotate around the first rotation axis 143 toward the engaging slot 111, so that the engaging part 141 engages with the engaging slot 111, and the container cover 1 is in the first state. In this embodiment, by providing the driving part 142 at both ends of the first rotation axis 143 with the engaging part 141, the user can change the state of the container cover 1 by pressing or lifting the driving part 142, thereby improving the convenience of operation.

[0105] It should be noted that when switching the state of the container cover 1 , the user may manually press the driving part 142 or lift the driving part 142 , or other structures may be provided in the container cover 1 to press or lift the driving part 142 .

[0106] In a specific embodiment, Figure 2 , Figure 6 and Figure 7 As shown, the second cover body 12 is further provided with a mounting portion 123 protruding upward along the height direction of the container cover 1 , the mounting portion 123 is provided with a mounting hole 124 , and the first rotating shaft 143 is rotatably connected to the second cover body 12 through the mounting hole 124 .

[0107] In this embodiment, the mounting portion 123 is made to protrude upward along the height direction of the container cover 1, so that after the limiting member 14 is connected to the mounting portion 123, a gap is provided between the limiting member 14 and the first top wall 127 of the second cover body 12, thereby preventing the limiting member 14 from interfering with the first top wall 127 of the second cover body 12 during the rotation process relative to the first top wall 127 of the second cover body 12.

[0108] In a specific embodiment, Figure 7 As shown, the cross-sectional area of ​​the clamping portion 141 is larger than the cross-sectional area of ​​the driving portion 142 .

[0109] In this embodiment, when the container cover is in the first state, the clamping portion 141 is clamped with the clamping slot, so that the cross-sectional area of ​​the clamping portion 141 is larger, which can improve the reliability of the clamping portion 141 and the clamping slot, thereby improving the stability when the second cover body drives the first cover body to rotate synchronously, and can extend the service life of the clamping portion 141. At the same time, the cross-sectional area of ​​the driving portion 142 is smaller, reducing the space of the container cover occupied by the driving portion 142.

[0110] In a specific embodiment, Figure 7 As shown, the distance between the first rotating shaft 143 and the driving portion 142 is greater than the distance between the first rotating shaft 143 and the clamping portion 141 .

[0111] In this embodiment, the driving part 142 and the clamping part 141 of the limiter 14 rotate around the first rotating shaft 143 to form a lever structure, in which the driving part 142 is a power arm and the clamping part 141 is a resistance arm, so that the distance between the first rotating shaft 143 and the driving part 142 is greater than the distance between the first rotating shaft 143 and the clamping part 141, so that the length of the power arm in the lever structure is greater than the length of the resistance arm, making it a labor-saving lever structure. At the same time, when the distance between the first rotating shaft 143 and the driving part 142 is greater than the distance between the first rotating shaft 143 and the clamping part 141, the smaller stroke of the driving part 142 can also achieve a larger stroke of the clamping part 141, so that the user can save more effort when pressing the driving part 142 to drive the clamping part 141 to rotate around the first rotating shaft 143, thereby improving the user experience.

[0112] In a specific embodiment, Figure 2 , Figure 3 and Figure 7 As shown, the limiting member 14 further includes a transition portion 144 of a bent structure, the transition portion 144 connects the clamping portion 141 and the driving portion 142 , and the transition portion 144 is rotatably connected to the first rotating shaft 143 .

[0113] In this embodiment, the driving portion 142 and the clamping portion 141 are connected by a transition portion 144 of a bending structure, so that a height difference is formed between the driving portion 142 and the clamping portion 141 in the height direction of the container cover 1. Therefore, in the process of switching the state of the container cover 1, the clamping portion 141 does not need to rotate too much around the first rotating shaft 143 to achieve clamping or disengagement with the clamping slot 111, thereby reducing the space required for the rotation of the clamping portion 141, thereby reducing the overall size of the container cover 1.

[0114] In a specific embodiment, Figure 2 and Figure 3 As shown, the container cover 1 further includes a first elastic member 15 , and the first elastic member 15 is elastically connected to the driving portion 142 .

[0115] In this embodiment, Figure 3 As shown, when the driving part 142 is pressed, the driving part 142 moves toward the first top wall 127 of the second cover body 12, so that the container cover 1 is in the second state, and the first elastic member 15 is compressed during this process. Figure 2 As shown, when the pressing of the driving part 142 is canceled, the driving part 142 can rotate around the first rotating shaft 143 away from the first top wall 127 of the second cover body 12 under the action of the rebound force of the first elastic member 15, so that the engaging part 141 rotates around the first rotating shaft 143 toward the engaging groove 111 and engages with it, thereby switching the container cover 1 from the second state to the first state. In this embodiment, by providing the first elastic member 15 connected to the driving part 142, when the pressing of the driving part 142 is canceled, the container cover 1 can automatically switch to the first state under the action of the rebound force of the first elastic member 15, without manual operation, and has the advantages of simple operation and simplified structure.

[0116] One end of the first elastic member 15 is elastically connected to the driving portion 142 , and the other end of the first elastic member 15 can be elastically connected to the second cover body 12 or the first cover body 11 .

[0117] In a specific embodiment, Figure 2 , Figure 6 and Figure 7 As shown, the second cover body 12 is further provided with a mounting groove 121 , and the driving portion 142 and the first elastic member 15 are located in the mounting groove 121 .

[0118] In this embodiment, the second cover body 12 is provided with an installation groove 121 to provide positioning for the installation of the driving part 142 and the first elastic member 15, and the first elastic member 15 is located in the installation groove 121, which can prevent the first elastic member 15 from tilting during compression or extension and affecting subsequent use.

[0119] Among them, along the distribution direction of the driving portion 142 and the clamping portion 141 , the installation slot 121 has an opening, so as to facilitate the driving portion 142 to move along the installation slot 121 during the rotation of the limiting member 14 .

[0120] In a specific embodiment, Figure 6 As shown, the first top wall 127 of the second cover body 12 has two convex ribs extending upward, and the two convex ribs and the first top wall 127 of the second cover body 12 form the above-mentioned installation groove 121.

[0121] The embodiment of the present application can be used for the container cover 1 shown in 1-4, and the container cover 1 can only include the first cover body 11 and the second cover body 12, and the stopper 14 rotatably connected to the first top wall 127 is exposed on the container cover 1, so that the user can directly press the driving part 142 of the stopper 14. Therefore, Figure 1-4 In the illustrated embodiment, the container cover 1 can be switched from the first state to the second state by the user directly pressing the driving portion 142 .

[0122] In other embodiments, Figure 8 As shown, the container cover 1 may further include a third cover body 13 movably connected to the second cover body 12. The third cover body 13 can be covered on the second cover body 12, or can open the second cover body 12. The third cover body 13 has a pressing portion 131, and the pressing portion 131 is used to press the limit member to make the limit member move relative to the second cover body 12 to achieve the engagement or release of the engaging portion and the engaging slot.

[0123] In this embodiment, the third cover 13 is movably connected with the second cover 12, so that the third cover 13 can move relative to the second cover 12, so that the third cover 13 covers the second cover 12, or opens the second cover 12, and when the third cover 13 covers the second cover 12, the stopper movably connected to the first top wall 127 can be hidden in the space between the third cover 13 and the second cover 12, so as to protect the stopper, and further prevent the risk of accidentally touching the stopper when it is exposed, resulting in the state switching of the container cover 1. The third cover 13 can drive the pressing part 131 to move relative to the second cover 12 during the movement relative to the second cover 12, so that the pressing part 131 can press the driving part of the stopper to drive the clamping part to clamp or release the clamping groove. Therefore, in this embodiment, the third cover 13 can not only be used to protect the second cover 12, the first cover 11 and the stopper, but also can be used to drive the stopper to move, so as to realize the switching of the container cover 1 between the first state and the second state.

[0124] Specifically, if Figure 8 and Fig. 9As shown, when the third cover body 13 is covered on the second cover body 12, the pressing portion 131 presses the stopper 14 to move relative to the second cover body 12, so that the engaging portion 141 moves to release the engaging portion from the engaging groove 111, so that the container cover 1 is in the second state; Fig.10 and Fig.11 As shown, when the third cover 13 opens the second cover 12, the third cover 13 drives the pressing portion 131 away from the limiting member 14, and under the elastic force of the elastic member 15, the second cover makes the engaging portion 131 engage with the engaging groove 111, so that the container cover 1 is in the first state. Therefore, in this embodiment, when the third cover 13 covers the second cover 12, the first cover 11 and the second cover 12 can rotate relative to each other, and when the second cover 12 is rotated, the cover cannot be opened, so as to prevent the user from accidentally touching and causing the container cover 1 to be opened incorrectly. When the third cover 13 opens the second cover 12, the first cover 11 is connected to the second cover 12, and when the second cover 12 is rotated, the first cover 11 can rotate relative to the container body to open or close the cover.

[0125] That is to say, in this embodiment, the container cover 1 can be released from the rotational connection with the container body only when the third cover 13 opens the second cover 12. Normally, when the third cover 13 covers the second cover 12, the two are locked by the locking member 16, such as Figure 8 As shown. When the user operates the locking member 16 to release the lock between the third cover body 13 and the second cover body 12, the third cover body 13 can open the second cover body 12. Therefore, when opening the cover, the user needs to first operate the locking member 16 to release the lock between the third cover body 13 and the second cover body 12, and then the first cover body 11 and the second cover body 12 can be connected through the clamping portion 141 and the clamping groove 111, and the cover can be opened only when the second cover body 12 is rotated. This cover opening design can further reduce the risk of wrong opening caused by accidental touch. In addition, this cover opening design also makes it easy for the user to distinguish the overall state of the container cover 1 through the state of the third cover body 13.

[0126] In a specific embodiment, Figures 8 to 10 As shown, the third cover body 13 and the second cover body 12 can be rotatably connected to facilitate the third cover body 13 to move relative to the second cover body 12, thereby driving the limiter 14 to move relative to the second cover body, thereby conveniently switching the state of the container cover 1.

[0127] Specifically, Figure 8 and Fig.10 As shown, one end of the third cover body 13 is rotatably connected to one end of the second cover body 12 via a second rotating shaft 18 .

[0128] In another specific embodiment, the third cover body and the second cover body can also be snap-fitted (not shown in the figure). Specifically, the inner wall of the third cover body can be circumferentially provided with a limiting portion, and the outer wall of the second cover body can be circumferentially provided with a limiting matching portion. When the third cover body is covered on the second cover body, the limiting portion can be snap-fitted with the limiting matching portion, and the third cover body and the second cover body can be locked by a locking member. When it is necessary to open the cover, the locking member is released, and an external force is applied to release the locking connection between the limiting portion and the limiting matching portion.

[0129] In the above embodiments, the limiting member 14 can be rotatably connected to the second cover body 12 .

[0130] In other embodiments, the limiting member 14 and the second cover body 12 may also be slidably connected, such as Figures 12 to 15 As shown, the first top wall 127 may also be provided with a slide rail 126 , the limiting member 14 and the first top wall 127 may be slidably connected via the slide rail 126 , and along the radial direction of the container cover 1 , the slide rail 126 is connected to the card slot 111 .

[0131] In this embodiment, the position of the stopper 14 is slidably connected to the first top wall 127 via the slide rail 126, so that the position of the stopper 14 can be adjusted. The slide rail 126 is connected to the slot 111 along the radial direction of the container cover 1, so that the stopper 14 can slide to engage or release the slot 111 via the slide rail 126, so that the user can change the state of the container cover 1 by sliding the stopper 14, thereby improving the convenience of operation. Fig.12 and Fig.13 As shown, the stopper 14 can slide along the slide rail 126 until it is released from the engagement with the card slot 111, so that the container cover 1 is in the second state; Fig.14 and Fig.15 As shown, the limiting member 14 can also slide along the slide rail 126 until it is engaged with the locking groove 111, so that the container cover 1 is in the first state.

[0132] In a specific embodiment, Figures 12 to 15 As shown, the stopper 14 has a connected clamping portion 141 and a driving portion 142, the clamping portion 141 is located in the slide rail 126, and the driving portion 142 has a first guide surface 142a, and a preset angle is formed between the first guide surface 142a and the slide rail 126. The pressing portion 131 on the third cover body 13 may also have an inclined second guide surface 133, and when the pressing portion 131 presses the stopper 14, the first guide surface 142a abuts against the second guide surface 133.

[0133] In this embodiment, the stopper 14 has a connected clamping portion 141 and a driving portion 142, so that the user can drive the clamping portion 141 to slide along the slide rail 126 through the driving portion 142, so that the clamping portion 141 is clamped or released from the clamping groove 111. The driving portion 142 has a first guide surface 142a, and the pressing portion 131 has a second guide surface 133. When the pressing portion 131 moves along the height direction of the container cover 1 to press the stopper 14, the first guide surface 142a and the second guide surface 133 that match each other can convert the movement of the pressing portion 131 along the height direction of the container cover 1 into the radial movement of the stopper 14 along the container cover 1, so as to realize driving the clamping portion 141 of the stopper 14 to slide radially along the slide rail 126 to switch the state of the container cover 1.

[0134] Specifically, Fig.12 and Fig.13 As shown, when the third cover body 13 is covered on the second cover body 12, the pressing portion 131 presses the driving portion 142 of the limiting member 14, which can drive the engaging portion 141 to move away from the card slot 111 until the engaging portion 141 is released from the card slot 111, thereby switching the container cover 1 to the second state. Therefore, in this embodiment, when the third cover body 13 is covered on the second cover body 12, the first cover body 11 and the second cover body 12 can rotate relative to each other, and when the second cover body 12 is rotated, the cover cannot be opened, which can prevent the user from accidentally touching the container cover 1 and causing it to be opened incorrectly. When the third cover body 13 is not covered on the second cover body 12, the user can drive the driving portion 142 of the limiting member 14 in the exposed state to drive the engaging portion 141 to move, so that the engaging portion 141 is engaged with the card slot 111, thereby placing the container cover 1 in the first state. Therefore, in this embodiment, when the third cover body 13 is not covered on the second cover body 12, the first cover body 11 and the second cover body 12 are connected to the card slot 111 through the card connection portion 141. When the second cover body 12 is rotated, the first cover body 11 can be driven to rotate synchronously, thereby realizing opening of the cover.

[0135] In a specific embodiment, Fig.12 and Fig.13 As shown, the limiting member 14 may further include a step portion 145 , which is connected to the driving portion 142 . The slide rail 126 has a second top wall 126 a , which is located between the clamping portion 141 and the step portion 145 along the height direction of the container cover 1 .

[0136] In this embodiment, the limiting member 14 has a step portion 145, and the second top wall 126a of the slide rail 126 is located between the clamping portion 141 and the step portion 145, which can limit the movement of the limiting member 14 along the height direction of the container cover 1, avoid the limiting member 14 from falling off during the sliding process, and improve the stability of the limiting member 14 when sliding in the slide rail 126.

[0137] In a specific embodiment, Figures 12 to 15 As shown, the container cover 1 may further include a second elastic member 19 , which is installed in the slide rail 126 . Along the radial direction of the container cover 1 , the second elastic member 19 is elastically connected to the clamping portion 141 and the first top wall 127 .

[0138] In this embodiment, when the driving part 142 is pushed, the driving part 142 moves away from the first cover body 11, thereby driving the engaging part 141 to move away from the engaging slot 111 until the engaging part 141 is released from the engaging slot 111, so that the container cover 1 is in the second state. During this process, the engaging part 141 squeezes the second elastic member 19, so that the second elastic member 19 is compressed. Fig.15 As shown, when the push driving portion 142 is cancelled, the engaging portion 141 can move toward the engaging slot 111 under the action of the rebound force of the second elastic member 19 to engage with the engaging slot 111, so that the container cover 1 is switched from the second state to the first state. In this embodiment, by providing the second elastic member 19 elastically connected to the engaging portion 141 and the first top wall 127, when the push driving portion 142 is cancelled, the container cover can automatically switch to the first state under the action of the rebound force of the second elastic member 19, without manual operation, and has the advantages of simple operation and simplified structure.

[0139] In a specific embodiment, Figures 16 to 18 As shown, the locking member 16 can be a fingerprint button. Specifically, the locking member 16 is rotatably connected to the second cover body 12 and is used to be snap-fitted with the third cover body 13. The locking member 16 may include a contact end 161 and a first snap-fitting end 162 connected to each other, and the third cover body 13 may include a second snap-fitting end 132, and the first snap-fitting end 162 and the second snap-fitting end 132 can be snap-fitted. The container cover 1 also includes a fingerprint panel, a circuit board, a drive assembly and a power supply (not shown in the figure), wherein the power supply can provide power to the fingerprint panel, the circuit board and the drive assembly respectively. The fingerprint panel is arranged inside the contact end 161. When the contact end 161 recognizes the user's fingerprint, the internal fingerprint panel can compare the collected fingerprint information with the pre-stored fingerprint information. When the collected fingerprint information is consistent with the pre-stored fingerprint information, the fingerprint panel successfully recognizes the fingerprint. When the fingerprint panel successfully recognizes the fingerprint, it can transmit a signal to the circuit board. The circuit board can drive the contact end 161 to move by controlling the driving component, so that the contact end 161 drives the first clamping end 162 to move, thereby clamping or releasing the first clamping end 162 with the second clamping end 132.

[0140] Specifically, when the fingerprint information recognized by the fingerprint panel is consistent with the pre-stored fingerprint information, the circuit board controls the driving component to work, and the driving component drives the contact end 161 to drive the first clamping end 162 to rotate away from the second clamping end 132 to release the clamping connection between the first clamping end 162 and the second clamping end 132. In some embodiments, the driving component may include a motor to drive the first clamping end 162 to rotate away from the second clamping end 132 to release the clamping connection between the first clamping end 162 and the second clamping end 132. In other embodiments, the driving component may also include an electromagnet, and accordingly, a magnet that repels the electromagnet is disposed inside the second clamping end 132, so that the first clamping end 162 rotates away from the second clamping end 132 under the action of the magnetic force to release the clamping connection between the first clamping end 162 and the second clamping end 132.

[0141] In addition, when the third cover body 13 is covered with the second cover body 12, the third cover body 13 and the second cover body 12 are locked by the locking member 16, and the pressing portion 131 of the third cover body 13 presses the driving portion of the limit member, so that the container cover 1 is in the second state. At this time, rotating the second cover body 12 cannot separate the container cover 1 from the container body, that is, if the fingerprint is not successfully recognized, the second cover body 12 cannot be opened, and the container cover 1 is always in the second state, so that the container cover 1 cannot be separated from the container body, further improving the safety of the liquid container.

[0142] In a specific embodiment, Fig.16 and Fig.17 As shown, the container cover 1 may also be provided with a straw 17 communicated with the container body.

[0143] In this embodiment, a straw 17 connected to the container body is provided in the container cover 1. When the third cover 13 is covered on the second cover 12, the water outlet 171 of the straw 17 is located in the accommodation space between the third cover 13 and the second cover 12, so as to protect the straw 17. When the second cover 12 is opened, the user can directly use the liquid container through the straw 17 without separating the container cover 1 from the container body. At the same time, in this embodiment, in order to improve the safety of the liquid container, the third cover 13 and the second cover 12 are connected through a locking member 16. When the locking member 16 successfully recognizes the fingerprint of the user, the locking member 16 can release the clamping of the third cover 13, so that the third cover 13 can move away from the second cover 12, so that the user can use the liquid container through the straw 17.

[0144] 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.
