Detailed Implementation

[0043] In the following description, only certain exemplary embodiments are briefly described. As those skilled in the art will recognize, the described embodiments can be modified in various ways without departing from the spirit or scope of this disclosure. Therefore, the drawings and description are considered to be exemplary in nature and not restrictive.

[0044] The structure, function, and implementation process of the button device, lid assembly, and cup in this embodiment will be illustrated below with reference to the accompanying drawings.

[0045] The button device provided in this application embodiment is applied to a cover assembly, which includes two cover bodies that fit together. For ease of description, the two cover bodies are respectively named the first cover body and the second cover body. When the button device provided in this application embodiment is applied to the cover assembly, it is used to lock the first cover body and the second cover body in the closed state, and can unlock the locked state.

[0046] The lid assembly of the button device provided in this application embodiment can be any of the following devices. An exemplary lid assembly can be a box, in which case the first lid assembly can be the box body and the second lid assembly can be the box lid; or, the lid assembly can be a cup, such as a thermos, in which case the first lid assembly can be the cup lid and the second lid assembly can be the cup body; or, the lid assembly can be an openable cup lid, for example, the first lid assembly can be a screw cap and the second lid assembly can be a top cap.

[0047] It should be understood that the cover assembly used in the button device provided in this application embodiment is not limited to the specific cover assembly of the above example, and can also be applied to other cover-fitting devices, which will not be described in detail here.

[0048] Please refer to Figure 1 The cup provided in this embodiment includes a cup body 3000 and a lid assembly 1000. The cup body 3000 is generally hollow and cylindrical. When the cup is a thermos, at least a portion of the cup body 3000 adopts a double-layer structure, with a vacuum insulation layer formed between the two layers. A spout is provided at one end of the cup body 3000 facing the lid assembly 1000, and the lid assembly 1000 is installed at the spout of the cup body 3000. The central axis of the lid assembly 1000 can coincide with the central axis of the cup body 3000. The lid assembly 1000 has a closed state (with the spout closed) and an open state (with the spout open).

[0049] In some examples, such as Figure 2 , Figure 3 and Figure 5 As shown, the cover assembly 1000 includes a first cover assembly 1300 and a second cover assembly 1100, as... Figure 3 and Figure 4 As shown, the lid assembly 1000 further includes a button device 1500, which is installed in the first lid assembly 1300. In one embodiment, the first lid assembly 1300 is a screw cap, and the second lid assembly 1100 is a top cap. The screw cap is hinged to the top cap via a hinge structure, and the screw cap is detachably connected to the cup body 3000. The button device 1500 and the hinge structure are located on opposite sides of the screw cap.

[0050] For ease of description, the following description uses the direction of the cup body 3000 facing the second lid assembly 1100 as "up" (or "top"), the direction of the cup body 3000 away from the second lid assembly 1100 as "down" (or "bottom"), the side of the first lid assembly 1300 where the button device 1500 is installed as "front", the side of the first lid assembly 1300 opposite to the button device 1500 as "rear", and the other two directions as left and right as examples. Specifically, the side of the first lid assembly 1300 where the button locking piece 1700 is installed is "left", and the side opposite to the left is "right". The three directions from front to back, from top to bottom, and from left to right are perpendicular to each other.

[0051] like Figure 3 , Figure 4 and Figure 6 As shown, the button device 1500 includes a button cap 1510 and a button body 1530. The button cap 1510 is a flexible body made of elastic material, used to receive the pressing force applied by the user and transmit it to the button body 1530. The elastic material used for the button cap 1510 includes, but is not limited to, food-grade silicone, latex, etc.

[0052] The button body 1530 is a rigid body made of a hard material. It is connected to the button cap 1510 and can engage with the second cover 1100, thereby keeping the second cover 1100 in the closed state. The hard material used for the button body 1530 may include, but is not limited to, hard plastics and hard alloys; among which, hard plastics may include, but are not limited to: PP (Polypropylene), PPSU (Polyphenylsulfone), and Tritan (Tritan Copolyeste).

[0053] The button body 1530 can be inserted into the first cover 1300 and can slide relative to the first cover 1300 under pressing force. The button body 1530 is provided with a locking member 1532 for engaging with the second cover 1100 when it is in the closed state.

[0054] The button cap 1510 is exposed on the outside of the first cover assembly 1300 and abuts against the outer wall of the first cover assembly 1300.

[0055] When the button cap 1510 is in the first state, the button body 1530 is in the first set position, and the engaging member 1532 engages with the second cover assembly 1100. In the first state, the button cap 1510 is not pressed.

[0056] When the button cap 1510 elastically deforms to the second state, the button body 1530 slides to the second set position, and the engaging member 1532 disengages from the second cover assembly 1100. At this time, the second cover assembly 1100 can be switched to the open state, that is, the mouth of the cup is opened. In the second state, the button cap 1510 is in the pressed state.

[0057] The second setting position is located inside the central axis of the cover assembly 1000 facing the first setting position, that is, the second setting position is located behind the first setting position. The specific positions of the second setting position and the first setting position can be set according to actual needs, as long as their corresponding functions can be achieved.

[0058] It should be noted that when the button body 1530 is in the second preset position, the button cap 1510 is in a pressed state. When the button body 1530 is in the first preset position, the button cap 1510 can be in a non-pressed state.

[0059] In the specific implementation process, when the second cover 1100 is in the closed state, in response to the pressing force along the direction of the central axis of the cover assembly 1000, the button body 1530 slides from the first set position to the second set position, and the locking member 1532 disengages from the second cover 1100, so that the second cover 1100 can switch from the closed state to the open state.

[0060] After the pressing force is released, the elastically deformed button cap 1510 can drive the button body 1530 to reset along the direction away from the central axis of the cover assembly 1000. Specifically, the button cap 1510 can drive the button body 1530 to reset to its original position along the direction away from the central axis of the cover assembly 1000. The original position can coincide with the first set position, or the original position can be located outside the first set position away from the central axis of the cover assembly 1000, which can be set according to actual needs.

[0061] It is understandable that when the original position is located outside the central axis of the cover assembly 1000 away from the first set position, the button body 1530 is in the first set position and the button cap 1510 is in the pressed state.

[0062] The button device 1500 provided in this embodiment, by providing a rigid button body 1530, can cooperate with the second lid assembly 1100 at a first predetermined position to keep the second lid assembly 1100 in a closed state with the cup body 3000 closed. By providing a flexible button cap 1510, when the user applies a pressing force to the button cap 1510 towards the central axis of the lid assembly 1000, the button cap 1510 can drive the button body 1530 to move along the central axis of the lid assembly 1000 during elastic deformation until the button body 1530 moves to the second predetermined position, at which point the engaging member 1532 disengages from the second lid assembly 1100, allowing the second lid assembly 1100 to switch to an open state with the cup mouth open. When the user removes the pressing force, the button cap 1510 can drive the button body 1530 to reset along the direction away from the central axis of the cup under its own elastic force. The button device 1500 of this embodiment provides elastic force through the elastic deformation of the button cap 1510, eliminating the need for a spring to achieve reset, avoiding the problems of spring rusting and falling off, and improving the reliability of the button device 1500. Moreover, this embodiment also helps to reduce the number of parts in the button device 1500, simplify the structure and reduce production and assembly costs.

[0063] In some embodiments, such as Figure 3 and Figure 4 As shown, the first cover assembly 1300 is provided with a button mounting part 1301 for mounting the button body 1530, and the button mounting part 1301 can provide space for the button body 1530 to slide.

[0064] In some examples, the button mounting portion 1301 can be a button mounting groove, which extends through the wall thickness of the first cover assembly 1300 and extends downward through the first cover assembly 1300 to form a slot. The button body 1530 can be an integral structure. When installing the button device 1500, the button body 1530 can be installed into the button mounting groove from the slot opening. In addition, the first cover assembly 1300 also includes a bottom cover, which is installed at the bottom end of the first cover assembly 1300 and can seal the slot opening of the button mounting groove to improve the installation reliability of the button device 1500. In other examples, the button mounting portion 1301 can be a button mounting hole, which extends through the wall thickness of the first cover assembly 1300. To reduce the installation difficulty of the button device 1500, the button body 1530 may include a first part and a second part connected to the rear end of the first part. The first part is embedded in the button cap 1510, and the second part is inserted into the button mounting hole and fixedly connected to the first part by welding, fusion or bonding.

[0065] In some embodiments, such as Figures 7 to 9 As shown, the button body 1530 also includes a main body portion 1531, which can be inserted through the first cover assembly 1300 and slide relative to the first cover assembly 1300. A locking member 1532 is fixed to one end of the main body portion 1531 located inside the first cover assembly 1300.

[0066] The main body 1531 can slide relative to the first cover 1300 in a front-rear direction. The main body 1531 may have opposing front and rear sides, and the portion of the main body 1531 near the front side may be embedded in the button cap 1510. The engaging member 1532 is disposed near the rear side of the main body 1531.

[0067] like Figure 6 As shown, when the engaging member 1532 is in the first set position, it engages with the first slot 1111 formed in the second cover body 1100. The second cover body 1100 has a downwardly extending engaging block 1110, which has the first slot 1111 formed, and the opening of the first slot 1111 is located on the rear side of the engaging block 1110.

[0068] like Figure 8As shown, the main body 1531 is provided with a clearance space 1531c for the passage of the latching block 1110 of the second cover 1100; the latching member 1532 is connected to the side of the main body 1531 facing the clearance space 1531c. For example, the portion of the main body 1531 near the rear has a side wall facing the clearance space 1531c, which is connected to the latching member 1532, and the middle portion of the side wall in the left-right direction is connected to the latching member 1532.

[0069] like Figures 6 to 9 As shown, when the second lid assembly 1100 is in the closed state, under the pressing force in the direction (i.e., backward) toward the central axis of the lid assembly 1000, the button body 1530 slides from the first set position to the second set position, and the locking member 1532 disengages from the first slot 1111, so that the second lid assembly 1100 can switch from the closed state to the open state of opening the cup.

[0070] In some embodiments, the main body 1531 has a frame structure and has two pairs of opposing sidewalls; one of the opposing sidewalls (i.e., the sidewall located on the front side) is embedded in the button cap 1510, and the other sidewall (i.e., the sidewall located on the rear side) is provided with a snap-fit ​​member 1532; the other pair of opposing sidewalls pass through the first cover body 1300.

[0071] Viewed from top to bottom, the frame structure of the main body 1531 is a rectangular ring structure or an oblong ring structure. The hollow part of the main body 1531 can form a clearance space 1531c.

[0072] In other examples, the main body 1531 may also be a plate structure, and an opening is provided in the middle of the plate structure to form a clearance space 1531c.

[0073] The size and shape of the clearance space 1531c can be set according to actual needs, as long as it can allow the snap-fit ​​block 1110 of the second cover assembly 1100 to pass smoothly.

[0074] In some embodiments, the engaging member 1532 may be block-shaped. Optionally, the upper surface of the engaging member 1532 near the keycap 1510 is inclined, and the inclined surface gradually slopes towards the keycap 1510 from top to bottom. In this way, the inclined surface can guide the engaging block 1110 of the second cover 1100 to move downward until the engaging member 1532 engages with the first slot 1111 in the engaging block 1110. The lower end surface of the engaging block 1110 is curved, such as an arc surface, to reduce friction between the engaging block 1110 and the engaging member 1532 and improve user operation convenience.

[0075] In practice, during the process of switching the second cover 1100 from the open state to the closed state, the latching block 1110 of the second cover 1100 can push the button body 1530 inward until the latching member 1532 is locked in the first slot 1111 of the latching block 1110, and then the button body 1530 remains in the first set position.

[0076] In other embodiments, when switching the second cover 1100 from the open state to the closed state, the second cover 1100 can be flipped downwards, allowing the latching block 1110 of the second cover 1100 to pass downwards through the button body 1530, and the first slot 1111 of the latching block 1110 can correspond to the latching member 1532 of the button body 1530. After the pressing pressure is released, when the button cap 1510 moves the button body 1530 to the first set position, the latching member 1532 engages with the first slot 1111. When it is necessary to switch the second cover 1100 from the closed state to the open state, the button device 1500 is pressed until the button body 1530 is in the second set position, and the latching member 1532 disengages from the first slot 1111.

[0077] like Figures 7 to 9 As shown, in some embodiments, the button body 1530 further includes a limiting boss 1534, which is connected to the main body portion 1531 and protrudes outward from the outside of the main body portion 1531. When the button body 1530 is in the first set position, the limiting boss 1534 can abut against the inner sidewall of the first cover assembly 1300 and limit the button body 1530.

[0078] For example, two opposing sides of the main body 1531 are respectively connected to limiting bosses 1534, and the two limiting bosses 1534 protrude in opposing directions. The limiting bosses 1534 can be disposed relatively close to the rear side of the main body 1531.

[0079] In practice, when the second cover assembly 1100 is switched to the open state, after the pressing force is removed, the button cap 1510 drives the button body 1530 to return to the limit boss 1534 and abut against the inner side wall of the first cover assembly 1300, so as to prevent the button body 1530 from slipping out of the button mounting part 1301.

[0080] Optionally, the front side of the limiting boss 1534 facing the first cover assembly 1300 is an inclined surface or an arc-shaped surface, so as to be able to adapt to the shape of the first cover assembly 1300 and have a relatively large contact area with the first cover assembly 1300, so as to avoid the first cover assembly 1300 or the limiting boss 1534 from cracking due to excessive local force.

[0081] like Figure 4 , Figures 7 to 9As shown, in some embodiments, the main body 1531 may be provided with a rib 1533 on at least one surface of the first cover 1300. The rib 1533 protrudes outward from the main body 1531 and is used to contact the first cover 1300. The size of the surface of the rib 1533 that contacts the first cover 1300 is smaller than the size of the surface on which the rib 1533 is located.

[0082] For example, the rib 1533 protrudes in the direction toward the wall of the button mounting portion 1301, and the rib 1533 extends in the sliding direction of the button body 1530; the rib 1533 is used to separate the body portion 1531 from the wall of the button mounting portion 1301, so as to reduce the friction between the button body 1530 and the first cover assembly 1300.

[0083] For example, raised ribs 1533 may be provided on the upper and lower surfaces of the main body 1531. The raised ribs 1533 on the upper surface of the main body 1531 protrude upward and extend in a front-to-back direction. The raised ribs 1533 on the lower surface of the main body 1531 protrude downward and extend in a front-to-back direction.

[0084] Optionally, the rib 1533 has a predetermined distance from at least one of the left and right edges of the connected surface. Thus, relative to the contact area between the upper and lower surfaces of the main body 1531 and the wall of the button mounting portion 1301, the contact area between the rib 1533 and the wall of the button mounting portion 1301 is relatively small, thereby reducing the frictional resistance during the movement of the button body 1530 relative to the button mounting portion 1301.

[0085] Optionally, the cross-section of the raised rib 1533 is semi-circular, wherein the cross-section of the raised rib 1533 is perpendicular to the sliding direction of the button body 1530. That is, the raised rib 1533 can be semi-cylindrical, and the axis of the raised rib 1533 is parallel to the sliding direction of the button body 1530. In this way, the raised rib 1533 can achieve line-surface contact with the wall of the button mounting part 1301, thereby reducing friction.

[0086] In other examples, the cross-section of the rib 1533 can also be semi-elliptical or trapezoidal, as long as it reduces the contact area with the wall of the button mounting part.

[0087] In this embodiment, the contact area between the rib 1533 and the button mounting portion 1301 is relatively small. When the button body 1530 moves relative to the button mounting portion 1301, the frictional resistance between the rib 1533 and the button mounting portion 1301 is relatively small, thereby improving the smoothness of the movement of the button body 1530 relative to the first cover assembly 1300.

[0088] In other embodiments, a ball bearing may be installed in the main body 1531, allowing the button body 1530 to roll into contact with the button mounting portion 1301 via the ball bearing, thereby improving the smoothness of movement of the button body 1530 relative to the second cover assembly 1100. Alternatively, the main body 1531 itself may include a cylindrical structure, through which the button body 1530 contacts the button mounting portion 1301, thereby reducing frictional resistance and improving the smoothness of movement of the button body 1530 relative to the second cover assembly 1100.

[0089] like Figure 9 As shown, in some embodiments, the main body 1531 includes two opposing first pillars 1531a, which are spaced apart and form a pair of opposing sidewalls of the pillar portion 1531. One of the first pillars 1531a is embedded in the button cap 1510, and the other first pillar 1531a is connected to a latching member 1532 on the side facing the clearance space 1531c.

[0090] Two first pillars 1531a are spaced apart in a front-to-back direction. The two first pillars 1531a are generally prismatic, for example, they are generally quadrangular prisms. Among them, the first pillar 1531a with the engaging member 1532 has at least a portion that can be arc-shaped so as to adapt to the inner ring 1320 when the button body 1530 is in the second set position.

[0091] The main body 1531 also includes two opposing second pillars 1531b, which extend along the sliding direction of the button body 1530, and the ends of the second pillars 1531b are respectively connected to the first pillar 1531a. The two second pillars 1531b constitute another pair of opposing sidewalls of the pillar part 1531.

[0092] Two second pillars 1531b are spaced apart and connected to two first pillars 1531a to form a roughly rectangular frame structure. The two second pillars 1531b are roughly prismatic in shape, for example, roughly quadrangular prisms. Each of the two second pillars 1531b is provided with a raised rib 1533, and the raised rib 1533 is provided on both the upper and lower surfaces of the second pillars 1531b.

[0093] The upper surface of the second column 1531b may have a left edge and a right edge. There is a gap between the left edge of the rib 1533 and the left edge of the second column 1531b, and a gap between the right edge of the rib 1533 and the right edge of the second column 1531b. These two gaps may be equal or unequal. For example, the ribs 1533 on the upper surfaces of the two second columns 1531b are positioned closer to the two opposite edges of the upper surfaces of the two second columns 1531b; that is, the rib 1533 on the upper surface of the right-hand second column 1531b is positioned closer to the right edge of its upper surface, and the rib 1533 on the upper surface of the left-hand second column 1531b is positioned closer to the left edge of its upper surface. The rib 1533 on the lower surface of the second column 1531b corresponds to the rib 1533 on the upper surface.

[0094] The two second pillars 1531b are connected to limiting bosses 1534 on opposite sides, and the two limiting bosses 1534 protrude in opposite directions.

[0095] In other embodiments, the portion of the second column 1531b that can slide within the button mounting portion 1301 may also be a cylindrical structure.

[0096] like Figure 8 As shown, in some embodiments, the button cap 1510 includes: a housing 1511 with an opening at one end and a plurality of grilles 1512 disposed within the housing 1511. The end of the housing 1511 with the opening forms an open end, and the open end of the housing 1511 abuts against the outer side wall of the first cover assembly 1300.

[0097] The outer casing 1511 can generally be oval or rectangular in shape. For example, the orthographic projection of the outer casing 1511 onto a reference plane parallel to the vertical direction is oval or rectangular, and the orthographic projection of the outer casing 1511 onto a reference plane parallel to the horizontal direction is also oval or rectangular. The specific shape of the outer casing 1511 can be set according to actual needs. The hollow portion of the outer casing 1511 is provided with multiple grid strips 1512, so that the keycap 1510 has multiple hollow portions. The keycap 1510 can provide a large deformation space. When the user applies a pressing force to the keycap 1510, the keycap 1510 is easy to deform, thereby reducing the pressing force and improving the convenience of pressing operation; it can also improve the elasticity of the keycap 1510 and improve the reliability of the keycap 1510 driving the key body 1530 to reset.

[0098] At least one grid bar 1512 extends axially along the cover assembly 1000. For example, all grid bars 1512 extend in a downward direction. Or, for example, a portion of the plurality of grid bars 1512 extends in a downward direction.

[0099] At least one bar 1512 is provided to extend in a left-to-right direction. For example, all bars 1512 are provided to extend in a left-to-right direction. Or, for example, a portion of a plurality of bars 1512 are provided to extend in a left-to-right direction.

[0100] Optionally, a portion of the grille bars 1512 extends downwards, and there are at least two of these grille bars 1512, which are spaced apart in the left-right direction. Another portion of the grille bars 1512 extends from left to right, and this portion connects two adjacent grille bars 1512 extending downwards. This arrangement facilitates the quick return of the button cap 1510 to its original shape.

[0101] Optional, such as Figure 9 As shown, a limiting groove 1535 can be provided in the second column 1531b of the button body 1530. Figure 8 As shown, the grid strip 1512 extending from left to right in the keycap 1510 can be locked in the limiting groove 1535, thereby improving the connection reliability between the keycap 1510 and the key body 1530.

[0102] Optionally, the limiting groove 1535 can be annular and extend circumferentially along the second column 1531b. Correspondingly, the portion of the grid bar 1512 that mates with the limiting groove 1535 is approximately a sleeve structure, with the second column 1531b passing through the central hole of the sleeve structure, and the wall of the sleeve structure being engaged within the limiting groove 1535. Specifically, in the portion of the grid bar 1512 that mates with the limiting groove 1535, the portion near the upper side protrudes upwards, and the portion near the lower side protrudes downwards, thus forming the sleeve structure.

[0103] In some embodiments, the inner wall of the closed end of the button body 1530 and the button cap 1510 are fixedly connected. The inner wall of the closed end of the button cap 1510 has a relatively large area, which is beneficial for the button body 1530 and the button cap 1510 to have a large connection area, thereby improving the connection reliability and allowing the button cap 1510 to evenly transmit the pressing pressure to the button body 1530.

[0104] In some embodiments, the button body 1530 and the button cap 1510 can be an integral structure. For example, the button body 1530 and the button cap 1510 can be formed into an integral structure by a two-material injection molding process, which facilitates embedding a portion of the button body 1530 in the button cap 1510 and improves the reliability of the button device 1500.

[0105] In other examples, the button body 1530 and the button cap 1510 can also be fixedly connected by means of adhesive bonding or welding.

[0106] In some embodiments, the surface of the keycap 1510 facing the first cover assembly 1300 has a shape adapted to a corresponding portion of the first cover assembly 1300, such as a matching arcuate surface, and the surface of the keycap 1510 facing the first cover assembly 1300 abuts against the outer sidewall of the first cover assembly 1300. This helps to improve the problem of dirt accumulating in the gap between the keycap 1510 and the first cover assembly 1300, and increases the contact area between the keycap 1510 and the first cover assembly 1300, improving the support stability of the first cover assembly 1300 for the keycap 1510, and helping the keycap 1510 to rebound.

[0107] In the case where the outer wall of the first cover assembly 1300 is an arc-shaped surface, the entire surface of the button cap 1510 facing the first cover assembly 1300 is an arc-shaped surface, and this surface can abut against the portion of the outer wall of the first cover assembly 1300 near the button mounting portion 1301.

[0108] like Figures 10 to 13 As shown, and continue to refer to Figure 3 and Figure 4 In some embodiments, the cover assembly 1000 further includes a key locking plate 1700, which is slidably mounted in the first cover assembly 1300, and the sliding direction of the key locking plate 1700 is along the circumferential direction of the first cover assembly 1300; when the key locking plate 1700 slides to the third predetermined position, the key locking plate 1700 limits the key body 1530 to the first predetermined position; when the key locking plate 1700 slides to the fourth predetermined position, the key locking plate 1700 avoids the key body 1530.

[0109] For example, when the second cover assembly 1100 is in the closed state, the button body 1530 is in the first set position. At this time, the button locking piece 1700 can be inserted into the side of the button body 1530 away from the button cap 1510 to prevent the button body 1530 from sliding towards the central axis of the cover assembly 1000 under the pressing force, so as to avoid the second cover assembly 1100 from opening due to accidental contact with the button cap 1510.

[0110] When it is necessary to switch the second cover assembly 1100 from the closed state to the open state, the key lock plate 1700 can move to the fourth preset position. The key lock plate 1700 disengages from the side of the key body 1530 away from the key cap 1510, allowing the key body 1530 to slide towards the central axis of the cover assembly 1000 under the pressing force. Figure 3 and Figure 4 As shown, the button lock plate 1700 is located in the fourth setting position.

[0111] To reduce the cost and failure rate of the cover assembly 1000, the key lock plate 1700 can be manually moved between the third and fourth preset positions. In other examples, the key lock plate 1700 can also be moved between the third and fourth preset positions by a drive component such as a motor.

[0112] In some embodiments, such as Figure 6 As shown, the first cover body 1300 has an outer ring body 1310 and an inner ring body 1320 arranged in a nested manner; the button body 1530 is inserted in the outer ring body 1310; the locking member 1532 is located between the outer ring body 1310 and the inner ring body 1320.

[0113] like Figures 9 to 12 As shown, the key lock plate 1700 includes: a stop portion 1710, a toggle portion 1720, a connecting portion 1730, and a limiting portion 1740. The stop portion 1710 and the limiting portion 1740 are located between the outer ring body 1310 and the inner ring body 1320, and are fixedly connected by the connecting portion 1730; the stop portion 1710 is close to the inner ring body 1320; the limiting portion 1740 is close to the outer ring body 1310; the toggle portion 1720 passes through the outer ring body 1310 and can slide circumferentially relative to the outer ring body 1310; the toggle portion 1720 and the limiting portion 1740 are fixedly connected.

[0114] When the key lock plate 1700 slides to the third preset position, the stop part 1710 inserts between the inner ring body 1320 and the key body 1530. When the key lock plate 1700 slides to the fourth preset position, the stop part 1710 avoids the key body 1530, and the limiting part 1740 engages with the first cover assembly 1300 to limit the key lock plate 1700 to the fourth preset position.

[0115] For example, the stop portion 1710, the actuating portion 1720, the connecting portion 1730 and the limiting portion 1740 can be integrally formed by a one-piece molding process.

[0116] For example, when the button body 1530 is in the first set position and the button locking piece 1700 is in the third set position, the stop part 1710 can be inserted between the button body 1530 and the inner ring body 1320. At this time, even if the button cap 1510 is subjected to a pressing operation force, the button body 1530 cannot move toward the central axis of the cover assembly 1000, thereby ensuring that the second cover 1100 is in the closed state.

[0117] When the second cover assembly 1100 needs to be opened, under the force of the button locking plate, the button locking plate 1700 moves to the fourth set position, and the stop part 1710 disengages from the button body 1530 and the inner ring body 1320, releasing the obstruction to the button body 1530, so that the button body 1530 can move towards the central axis of the cover assembly 1000, thereby causing the locking member 1532 to disengage from the first slot 1111.

[0118] The actuating part 1720 is slidably installed in the locking plate mounting hole 1302 of the outer ring body 1310, and is used to drive the stop part 1710 to move under the actuating force, so as to realize the sliding of the key locking plate 1700 between the third set position and the fourth set position. The locking plate mounting hole 1302 is an elongated hole that passes through the outer ring body 1310 and extends circumferentially along the outer ring body 1310; the actuating part 1720 is exposed on the outside of the cover assembly 1000, and can drive the stop part 1710 to slide around the central axis of the cover assembly 1000 under the actuating force.

[0119] The stop portion 1710 is plate-shaped. For example, the shape of the stop portion 1710 can be adapted to fit the inner ring body 1320. For instance, if the position corresponding to the inner ring body 1320 and the stop portion 1710 is arc-shaped, then the shape of the stop portion 1710 is adapted to the arc shape of the inner ring body 1320. In other examples, the stop portion 1710 can be flat.

[0120] The actuating part 1720 is cylindrical, such as cylindrical, prismatic, or elliptical. The end of the actuating part 1720 away from the central axis of the cover assembly 1000 is exposed, making it easy for the user to apply actuating force to the actuating part 1720.

[0121] The connecting portion 1730 is inclined, so that the end of the connecting portion 1730 facing the stop portion 1710 can approach the inner ring body 1320, and the end of the connecting portion 1730 facing the limiting portion 1740 can approach the outer ring body 1310.

[0122] The limiting part 1740 can be in the form of a sheet, and the shape of the limiting part 1740 can be adapted to the outer ring body 1310. For example, when the position corresponding to the outer ring body 1310 and the limiting part 1740 is arc-shaped, the shape of the limiting part 1740 is adapted to the arc shape of the outer ring body 1310.

[0123] In this embodiment, by reasonably setting the shapes of the stop part 1710 and the limiting part 1740, the sliding of the key lock piece 1700 can be limited, so that the key lock piece 1700 can slide smoothly along the annular space between the inner ring body 1320 and the outer ring body 1310.

[0124] In practice, when the user applies a tossing force to the toggle part 1720 in a direction away from the button mounting part 1301, the toggle part 1720 slides circumferentially along the outer ring body 1320, causing the button locking piece 1700 to move from the third set position to the fourth set position. The stop part 1710 disengages from the button body 1530 and the inner ring body 1320, thereby releasing the restriction on the button body 1530. Thus, under the pressing force applied by the user, the button body 1530 can move toward the central axis of the cover assembly 1000, allowing the locking piece 1532 of the button body 1530 to disengage from the first slot 1111 of the second cover 1100, thereby allowing the second cover 1100 to switch from the closed state to the open state.

[0125] When the user applies a toggle force to the toggle part 1720 in the direction toward the button mounting part 1301, the toggle part 1720 slides circumferentially along the outer ring body 1320, causing the button locking piece 1700 to move from the fourth set position to the third set position. The stop part 1710 is clamped between the button body 1530 and the inner ring body 1320 to restrict the movement of the button body 1530 toward the central axis of the cover assembly 1000, thereby allowing the button body 1530 to remain in the first set position and keeping the second cover 1100 in the closed state.

[0126] In some embodiments, such as Figure 10 As shown, the end of the limiting part 1740 away from the stop part 1710 has an elastic arm 1741; the elastic arm 1741 has a first engaging protrusion 1741a; a second engaging protrusion 1303 is provided inside the first cover body 1300; when the button lock piece 1700 slides to the fourth set position, the first engaging protrusion 1741a engages with the second engaging protrusion 1303.

[0127] For example, the first engaging protrusion 1741a is disposed near the end of the elastic arm 1741 away from the stop portion 1710, and the first engaging protrusion 1741a is disposed to protrude upward from the upper surface of the elastic arm 1741.

[0128] The upper end of the elastic arm 1741 has a receiving space 1742, and the receiving space 1742 is located on the side of the first engaging protrusion 1741a facing the stop portion 1710. The receiving space 1742 is used to cooperate with the second engaging protrusion 1303 when the actuating portion 1720 is in the fourth set position.

[0129] When the user applies a toggle force to the toggle part 1720 in a direction away from the button mounting part 1301, the elastic arm 1741 can move in a direction away from the button mounting part 1301, and the elastic arm 1741 can deform so that the first engaging protrusion 1741a can pass under the second engaging protrusion 1303 until the first engaging protrusion 1741a moves to the side of the second engaging protrusion 1303 away from the button mounting part 1301. At this time, the second engaging protrusion 1303 is accommodated in the accommodating space 1742, and the button locking piece 1700 moves to the fourth set position.

[0130] By setting the elastic arm 1741, when the button lock plate 1700 moves to the third or fourth set position, the interaction between the elastic arm 1741 in the button lock plate 1700 and the second engaging protrusion 1303 in the first cover assembly 1300 can provide users with a good user experience.

[0131] In some embodiments, the cover assembly 1000 further includes a display panel 2010, a circuit board 2020, and a temperature sensor 2030. The display panel 2010 and the temperature sensor 2030 are electrically connected to the circuit board 2020, respectively. The display panel 2010 is used to display the detection result of the temperature sensor 2030.

[0132] The second cover assembly 1100 includes a dust cover 1120 and an inner protective cover 1130 installed inside the dust cover 1120. The inner protective cover 1130 and the dust cover 1120 form an installation space, and the circuit board 2020 is located within the installation space.

[0133] The display panel 2010 is mounted on the dust cover 1120, and the display area of ​​the display panel 2010 is exposed at the end of the dust cover 1120 away from the cup body 3000.

[0134] Temperature sensor 2030 is fixed in inner protective cover 1130, and the temperature sensing probe of temperature sensor 2030 is exposed outside inner protective cover 1130 and is used to detect the temperature in cup body 3000.

[0135] For example, the dust cover 1120 is generally cylindrical and has a lower opening. An inner protective cover 1130 is installed inside the dust cover 1120. The lower part of the inner protective cover 1130 is generally cylindrical or conical, and the upper part of the inner protective cover 1130 is expanded to fit with the protective cover.

[0136] A third seal may be provided between the dust cover 1120 and the inner protective cover 1130 to improve the sealing reliability of the installation space. The third seal may be an O-ring.

[0137] The circuit board 2020 can be fixed in the installation space by means of snap-fit ​​or screw-fit. The display panel 2010 can be a touch panel.

[0138] In this embodiment, the temperature inside the cup can be displayed in real time through the above settings, so that users can know the temperature of the liquid inside the cup in a timely manner and avoid the liquid inside the cup being too high or too low and affecting the user's use. This is especially true in the case of a thermos cup, where the current temperature inside the thermos cup can be monitored.

[0139] In some embodiments, where the first cap assembly 1300 is a screw cap and the second cap assembly 1100 is a top cap, such as... Figure 6 As shown, in the screw cap, the top of the outer ring 1310 is connected to the inner ring 1320. The outer ring 1310 can be integrally formed with the inner ring 1320. The central axes of the outer ring 1310 and the inner ring 1320 coincide.

[0140] The inner wall of the outer ring 1310 is provided with an internal thread, and the top of the cup body 3000 is provided with an external thread. The internal thread of the outer ring 1310 and the external thread of the cup body 3000 are engaged, thereby detachably connecting the cap to the cup body 3000.

[0141] The inner ring 1320 extends into the cup body 3000, and a first seal 1910 is provided between the outer wall of the inner ring 1320 and the inner wall of the cup body 3000. The first seal 1910 is used to prevent liquid in the cup body 3000 from leaking through the fitting gap between the cap and the cup body 3000. The first seal 1910 is annular, and its shape is adapted to the shape of the space between the inner ring 1320 and the cup body 3000.

[0142] When the top cover is in the closed position, the top cover is provided with a second seal 1930, which abuts against the screw cap to prevent liquid in the cup body 3000 from leaking from the mating point between the screw cap and the top cover. The second seal 1930 is generally annular. Optionally, the second seal 1930 extends upward to the top of the inner ring 1320, and the second seal 1930 continues to extend outward, so that a portion of the second seal 1930 abuts between the top of the screw cap and the top cover.

[0143] This embodiment, through the above-described settings, can improve the ease of installation of the button device 1500, and also ensure the sealing reliability between the screw cap and the cup body 3000, as well as the sealing reliability between the screw cap and the top cover.

[0144] Please refer to Figure 6 , Figure 14 , Figure 15 as well as Figure 16In some embodiments, where the first cover assembly 1300 and the second cover assembly 1100 are connected by a hinge structure, the hinge structure includes a hinge shaft 2050 and a torsion spring 2060, and the axial direction of the hinge shaft 2050 can be parallel to the left-right direction. The second cover assembly 1100 can be provided with two bearing seats 1123, which are spaced apart in the left-right direction; the first cover assembly 1300 is provided with a bushing 1330, which can be located between the two bearing seats 1123; the hinge shaft 2050 passes through the bearing seats 1123 and the bushing 1330, and the hinge shaft 2050 is fixedly connected to the bearing seats 1123 and rotatably connected to the bushing 1330. A torsion spring 2060 is sleeved on the outside of the rotating shaft. One end of the torsion spring 2060 is fixedly connected to the first cover assembly 1300, and the other end of the torsion spring 2060 abuts against the second cover assembly 1100. Moreover, when the second cover assembly 1100 switches from the open state to the closed state, the torsion spring 2060 will generate torque and store energy so that when the second cover assembly 1100 is released from the fixed position using the button device 1500, the second cover assembly 1100 can rotate to the open state under the action of the energy stored in the torsion spring 2060.

[0145] The hinge shaft 2050 can be a hollow shaft, allowing the user to thread a hanging rope through it. Two torsion springs 2060 can be present, symmetrically distributed about a preset center plane of the cup, parallel to both the vertical and horizontal directions. A preset gap can exist between the torsion springs 2060 and the hinge shaft 2050 to prevent wear between them.

[0146] In other embodiments, the first cover assembly 1300 may be provided with two bearing seats 1123, and the second cover assembly 1100 may be provided with a bushing 1330. The specific implementation process is similar to the example above.

[0147] In some embodiments, please refer to Figures 14 to 16 The second lid assembly 1100 is provided with a stop protrusion 1121 and a rotating groove 1122. When the cup is normally placed and the second lid assembly 1100 and the first lid assembly 1300 are in the closed state, the stop protrusion 1121 is located above the rotating groove 1122. The outer wall of the bushing 1330 of the first lid assembly 1300 is provided with a first locking rib 1331 and a second locking rib 1332. The first locking rib 1331 is located above the second locking rib 1332.
