Description

Cup lid and cup Technical Field

[0001] This application relates to the field of consumer goods technology, and in particular to a cup lid and a cup. Background Technology

[0002] In daily life, water cups are essential tools for drinking water, and their safety and hygiene are crucial to our health. However, most water cups on the market still have shortcomings in terms of safety, mainly in two aspects: the safety of drinking water and privacy. Existing water cups can be easily opened by others, which may not only lead to unsafe incidents, such as malicious throwing, but also the spread of diseases due to misuse or cross-use. Currently, the safety design of most water cups on the market mainly focuses on the buckle function on the lid to prevent the cup from being accidentally opened. Technical issues

[0003] However, this design is not sufficient to provide adequate safety. For example, some water cups use a spring-loaded lid structure, which, while enabling opening and closing, still offers limited safety. Technical solutions

[0004] To improve upon at least some of the above-mentioned shortcomings or deficiencies, embodiments of this application provide a cup lid and a cup using the cup lid. By providing a specific positioning structure on the cup lid, when the lid is in the closed state, the positioning structure disengages from the inner lid, preventing the outer lid from engaging with the inner lid. In this case, when the user rotates the cup lid, the inner lid will not rotate accordingly, preventing the user from unscrewing the inner lid and the cup body, thus preventing others from easily opening the cup and ensuring personal safety and privacy.

[0005] On one hand, one embodiment of this application provides a cup lid, which includes an upper lid, an outer lid, an inner lid, and a positioning structure. The outer lid is connected to the upper lid, and the upper lid can be in a closed state and an open state relative to the outer lid. The inner lid is located on the side of the outer lid opposite to the upper lid and is connected to the outer lid. The positioning structure includes a positioning member, a first magnetic member, and a second magnetic member. The second magnetic member is located inside the upper lid, and the positioning member and the first magnetic member are located on the outer lid. The positioning member is connected to the first magnetic member, and the first magnetic member corresponds to the second magnetic member and is located on the side of the positioning member closer to the second magnetic member. Wherein, when the upper lid is in the open state, the positioning member is engaged with the inner lid; when the upper lid is in the closed state, the second magnetic member and the first magnetic member attract each other at one end, and the positioning member moves towards the second magnetic member under the action of the first magnetic member to disengage from the inner lid.

[0006] In one embodiment, the positioning member is provided with a positioning block, the inner cover is provided with a receiving groove, the bottom of the receiving groove is provided with a plurality of limiting protrusions, and the plurality of limiting protrusions are spaced apart to form a plurality of limiting gaps; when the upper cover is in the open state, the positioning block is embedded in one of the plurality of limiting gaps.

[0007] In one embodiment, the positioning block has a first inclined surface at one end near the inner cover, and the plurality of limiting protrusions have a plurality of second inclined surfaces at one end near the top of the receiving groove, with the first inclined surface and the second inclined surface corresponding one-to-one.

[0008] In one embodiment, the outer cover has a positioning post on the side adjacent to the inner cover, the positioning post has a through hole, the side wall of the positioning post has an opening that communicates with the through hole, the positioning member is connected in the through hole and located at one end of the through hole adjacent to the inner cover, and the positioning block extends out of the positioning post through the opening.

[0009] In one embodiment, the cup lid further includes a mounting plate that is connected to the outer cover and covers one end of the through hole near the inner cover.

[0010] In one embodiment, in the direction of movement of the positioning member, the maximum distance between the positioning member and the mounting plate is greater than or equal to the maximum height of the plurality of limiting protrusions.

[0011] In one embodiment, the cup lid further includes a snap-fit ​​structure, the snap-fit ​​structure including a first snap-fit ​​member and a second snap-fit ​​member, the first snap-fit ​​member being disposed inside the upper cover and located on the side of the upper cover near the outer cover; the second snap-fit ​​member being disposed on the outer cover and located on the side of the outer cover near the upper cover, the second snap-fit ​​member corresponding to and matching the first snap-fit ​​member.

[0012] In one embodiment, the cup lid further includes a fingerprint recognition structure and a main control circuit. The fingerprint recognition structure is electrically connected to the main control circuit, and the main control circuit is connected to the buckle structure. The fingerprint recognition structure and the main control circuit are disposed inside the upper cover or the outer cover, and the fingerprint recognition structure is partially exposed outside the upper cover or the outer cover.

[0013] On the other hand, another embodiment of this application provides a cup, which includes a cup body and the aforementioned cup lid, wherein the inner cover of the cup lid is threadedly connected to the cup body.

[0014] In one embodiment, the cup body includes an outer cup body and a cup liner, the cup liner being disposed in the inner cavity of the outer cup body, and a sealed interlayer cavity being formed between the outer cup body and the cup liner, the interlayer cavity being provided with heat-insulating material or being a vacuum cavity. Beneficial effects

[0015] By incorporating a positioning element, a first magnetic element, and a second magnetic element on the cup lid, along with their relative positions, when the lid is closed, the first magnetic element, due to the attraction between itself and the second magnetic element, causes the positioning element to move and disengage from the inner lid. This prevents the outer lid from engaging with the inner lid, and the inner lid does not rotate with the outer and upper lids, thus preventing the user from unscrewing the inner lid and the cup body. When the lid is open, the positioning element, under its own weight, engages with the inner lid, causing the inner lid to engage with the outer lid. At this point, the inner lid rotates with the outer and upper lids, allowing the user to unscrew or close the inner lid and the cup body for drinking or other operations. Attached Figure Description

Embodiments of the present invention

[0029] The technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, and not all embodiments. Based on the embodiments of this application, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the scope of protection of this application.

[0030] As shown in Figures 1 and 2, one embodiment of this application provides a cup. The cup can be, for example, a cup for drinking water, or a cup for holding coffee, tea, or other liquids. The cup includes, for example, a cup body 10 and a lid 20. The cup body 10 and the lid 20 are connected, for example, by a threaded connection. The user can open the cup by unscrewing the lid 20.

[0031] The cup can also be, for example, a thermos. The cup body 10 may also include an outer cup body 110 and a cup liner 120. The cup liner 120 is disposed in the inner cavity of the outer cup body 110. A closed interlayer cavity 130 is formed between the outer cup body 110 and the cup liner 120. The interlayer cavity 130 is provided with heat-insulating material to enhance the heat-insulating effect. The heat-insulating material may include, for example, vacuum insulation material, foam plastic, glass fiber, etc.; or the interlayer cavity 130 may be, for example, a vacuum cavity.

[0032] Specifically, as shown in Figures 2 to 5, the cup lid 20 includes an upper lid 210, an outer lid 220, an inner lid 230, and a positioning structure 30. The outer lid 220 is connected to the upper lid 210, and the upper lid 210 can be in a closed state or an open state relative to the outer lid 220. The inner lid 230 is located on the side of the outer lid 220 opposite to the upper lid 210 and is connected to the outer lid 220. The positioning structure 30 includes a positioning member 310, a first magnetic member 320, and a second magnetic member 330. The second magnetic member 330 is located inside the upper lid 210, and the positioning member 310 and the first magnetic member 320 are located on the outer lid 220. The positioning member 310 is connected to the first magnetic member 320, and the first magnetic member 320 corresponds to the second magnetic member 330 and is located on the side of the positioning member 310 closer to the second magnetic member 330. When the upper cover 210 is in the open state, the positioning member 310 is engaged with the inner cover 230; when the upper cover 210 is in the closed state, the second magnetic member 330 and the first magnetic member 320 attract each other at one end, and the positioning member 310 moves towards the second magnetic member 330 under the action of the first magnetic member 320, so as to disengage from the inner cover 230.

[0033] Specifically, the upper cover 210 and the outer cover 220 are rotatably connected, for example, by a pivot hinge, and the upper cover 210 can switch between the closed state and the open state by rotating. The second magnetic member 330 and the first magnetic member 320 are, for example, magnets with opposite magnetic poles at one end, or one of the first magnetic member 320 and the second magnetic member 330 is, for example, a magnet, and the other is, for example, an object that can be attracted and moved by a magnet, such as iron, nickel, cobalt and their alloys.

[0034] Furthermore, as shown in Figures 3 and 5, the inner wall of the outer cover 220 is provided with, for example, an annular groove 223, and the outer wall of the inner cover 230 is provided with, for example, an annular protrusion 232, which is embedded in the annular groove 223. When the upper cover 210 is in the closed state, the user rotates the cup lid, and the annular groove 223 of the outer cover 220 slides outside the annular protrusion 232, causing the outer cover 220 to slide relative to the inner cover 230, making it impossible to unscrew the inner cover 230 from the cup body 10.

[0035] As shown in Figure 2, when the upper cover 210 is closed relative to the outer cover 220, the first magnetic 320 and the second magnetic 330 attract each other at their closest points. The first magnetic 320 moves towards the second magnetic 330 due to the magnetic force between them. The first magnetic 320 is fixed to the positioning member 310, and the first magnetic 320 drives the positioning member 310 to move towards the second magnetic 330, causing the positioning member 310 to disengage from the inner cover 230. The inner cover 230 and the outer cover 220 are no longer engaged. At this time, when the user rotates the cup lid 20, only the upper cover 210 and the outer cover 220 rotate together; the inner cover 230 does not rotate with the outer cover 220. This prevents the user from easily opening the inner cover 230 and the cup body 10, thus preventing the cup from being easily opened and used by others or maliciously dumped into it, improving safety and privacy, and preventing the spread of disease.

[0036] As shown in Figure 3, when the upper cover 210 is open relative to the outer cover 220, the first magnetic suction member 320 is no longer moved by the attraction between itself and the second magnetic suction member 330. Due to gravity, the first magnetic suction member 320 and the positioning member 310 move towards the inner cover 230, causing the positioning member 310 to engage with the inner cover 230, and the inner cover 230 and the outer cover 220 are locked. When the user rotates the cup lid 20, the inner cover 230 will rotate together with the outer cover 220 and the upper cover 210 to open or tighten the cup lid 20, allowing the user to fill the cup body 10 with liquid, clean the cup, or drink water.

[0037] As shown in Figures 8, 9, and 10, in one embodiment, the positioning member 310 is provided with a positioning block 311, and the inner cover 230 is provided with a receiving groove 231, which is, for example, a circular groove. The bottom of the receiving groove 231 is provided with multiple limiting protrusions 40, which are spaced apart to form multiple limiting gaps 410. When the upper cover 210 is in the open state, the first magnetic member 320 is no longer subject to the attractive force between itself and the second magnetic member 330. The first magnetic member 320 moves towards the bottom of the receiving groove 231 under the influence of gravity, causing the positioning block 311 to embed in one of the multiple limiting gaps 410, and the positioning member 310 engages with the limiting protrusion 40. When the upper cover 210 is in the closed state, the first magnetic member 320 drives the positioning member 310 to move towards the upper cover 210, the positioning block 311 moves away from the limiting gap 410, and the positioning member 310 releases its engagement with the limiting protrusion 40.

[0038] Furthermore, the positioning block 311 has a first inclined surface 313 near the inner cover 230, and multiple limiting protrusions 40 have multiple second inclined surfaces 420 near the top of the receiving groove 231, with the first inclined surface 313 and the second inclined surface 420 corresponding one-to-one. During the opening of the upper cover 210, the positioning member 310 moves under the action of gravity, and the first inclined surface 313 slides onto the second inclined surface 420. Through the relative angle and shape of the inclined surface design, the positioning member 310 is smoothly connected to the second inclined surface 420, reducing the friction and resistance when the positioning member 310 moves and is embedded in the limiting gap 410, so that the positioning member 310 can be smoothly embedded in the limiting gap 410.

[0039] To enhance the stability of the engagement between the positioning member 310 and the limiting protrusion 40, the positioning block 311 includes a first positioning block 3111 and a second positioning block 3112 that are opposite to each other and spaced apart, with a positioning space 312 formed between the first positioning block 3111 and the second positioning block 3112. When the upper cover 210 is in the open state, the positioning member 310 moves to engage with the inner cover 230. One of the multiple limiting protrusions 40 is located in the positioning space 312, and the first positioning block 3111 and the second positioning block 3112 are respectively located in any one of the multiple limiting gaps 410, thereby enhancing the stability of the engagement between the positioning member 310 and the inner cover 230.

[0040] Furthermore, the positioning member 310 may be provided with a positioning sleeve 314, with an opening at one end of the positioning sleeve 314 facing the outer cover 220, the first magnetic suction member 320 located inside the positioning sleeve 314, and the positioning block 311 disposed on the side wall of the positioning sleeve 314 near the inner cover 230.

[0041] As shown in Figures 6 and 7, in one embodiment, the outer cover 220 has a positioning post 221 on the side adjacent to the inner cover 230. A through hole 2211 is provided within the positioning post 221, and an opening 2212 is provided on the side wall of the positioning post 221, communicating with the through hole 2211. A positioning member 310 is connected within the through hole 2211 and located at one end of the through hole 2211 adjacent to the inner cover 230. The positioning block 311 extends out of the positioning post 221 through the opening 2212. The positioning post 221 provides motion guidance for the positioning member 310 and the first magnetic member 320, ensuring their correct positioning within the positioning post 221. The positioning member 310 and the first magnetic member 320 can move within the through hole 2211 of the positioning post 221. When the outer cover 220 is connected to the inner cover 230, the positioning post 221 is partially located within the receiving groove. When the upper cover 210 is closed and the outer cover 220 is rotated, the positioning post 221 will rotate within the receiving groove 231 along with the outer cover 220. The end of the positioning post 221 near the inner cover 230 can abut against the bottom of the receiving groove 231, ensuring that the positioning structure 30 does not leave the positioning post 221 and ensuring the effectiveness of the cup lid 20.

[0042] Furthermore, the cup lid 20 also includes a mounting plate 222, which connects to the outer cover 220 and covers the end of the through hole 2211 near the inner cover 230. This ensures that the positioning structure 30 is located within the positioning post 221 and will not fall out of the positioning post 221 during use.

[0043] In one embodiment, in the direction of movement of the positioning member 310, the maximum gap between the positioning member 310 and the mounting plate 222 is greater than or equal to the maximum height of the plurality of limiting protrusions 40. When the upper cover 210 is in the closed state, the first magnetic member 320 moves toward the direction closer to the second magnetic member 330, that is, the first magnetic member 320 drives the positioning member 310 to move toward the upper cover 210. At this time, the gap between the positioning member 310 and the mounting plate 222 increases. When the upper cover 210 is in the open state, the positioning member 310 moves toward the direction closer to the inner cover 230 due to gravity, and the gap between the positioning member 310 and the mounting plate 222 decreases. Therefore, when the upper cover 210 is in the closed state, the gap between the positioning member 310 and the mounting plate 222 is the maximum gap. The heights of the plurality of limiting protrusions 40 may be the same or may not be the same. When the top cover 210 is open, the positioning member 310 moves to make its bottom end contact the inner cover 230. When the top cover 210 is closed, the positioning member 310 moves away from the inner cover 230. The movement distance of the positioning member 310 should be greater than or equal to the maximum height of the multiple limiting protrusions 40 so that the positioning block 311 can completely disengage from the limiting protrusions 40. The movement distance of the positioning member 310 is the maximum gap between the positioning member 310 and the mounting plate 222. Therefore, when the maximum gap is greater than the maximum height, it can be ensured that the positioning block 311 can completely disengage from the limiting protrusions 40, ensuring that when the top cover 210 is closed, the positioning block 311 will not be located in the limiting gap 410, the limiting protrusions 40 will not be located in the positioning space 312, and the inner cover 230 will not rotate with the outer cover 220.

[0044] As shown in Figures 2 and 3, in one embodiment, the cup lid 20 further includes a latching structure 50, which includes a first latching member 510 and a second latching member 520. The first latching member 510 is disposed inside the upper cover 210, located on the side of the upper cover 210 near the outer cover 220; the second latching member 520 is disposed on the outer cover 220, located on the side of the outer cover 220 near the upper cover 210, and the second latching member 520 corresponds to and matches the first latching member 510. The upper cover 210 can be opened or closed by rotating the first latching member 510 or the second latching member 520. When the user needs to close the upper cover 210, the downward pressure of the upper cover 210 will cause the first latching member 510 to press against the second latching member 520, ultimately engaging the first latching member 510 with the second latching member 520.

[0045] As shown in Figure 12, in one embodiment, the cup lid 20 further includes a fingerprint recognition structure 60 and a main control circuit 70. The fingerprint recognition structure 60 is electrically connected to the main control circuit 70, which is connected to the latching structure 50. The fingerprint recognition structure 60 and the main control circuit 70 are disposed inside the upper cover 210 or the outer cover 220, with a portion of the fingerprint recognition structure 60 exposed outside the upper cover 210 or the outer cover 220. When a user needs to unlock the cup, the user places their finger on the fingerprint recognition structure 60. The fingerprint recognition structure recognizes the fingerprint of the person unlocking the cup, and the main control circuit 70 determines whether to drive the control device to control the latching structure 50 based on the fingerprint recognized by the fingerprint recognition structure 60. If the fingerprint matches the fingerprint of the cup holder, the main control circuit 70 drives the control device to open the latching structure 50, allowing the user to use the cup and rotate the lid 20 normally. If the fingerprint does not match the fingerprint of the cup holder, the latching structure 50 remains closed, and the upper cover 210 is in the closed state. At this time, the outer cover 220 and the inner cover 230 are not engaged, and even rotating the lid 20 cannot open the cup body 10. Referring to Figure 1, the fingerprint recognition structure 60 and the main control circuit 70 are located inside the upper cover 210, with a portion of the fingerprint recognition structure 60 exposed outside the upper cover 210. The main control circuit 70 is connected to the first latch 510, and the main control circuit 70 controls the first latch 510 to rotate within the upper cover 210 to engage or disengage the second latch 520. Referring to Figure 11, the fingerprint recognition structure 60 and the main control circuit 70 are located inside the outer cover 220, with a portion of the fingerprint recognition structure 60 exposed outside the outer cover 220. The main control circuit 70 is connected to the second latching member 520, and the main control circuit 70 controls the second latching member 520 to rotate on the outer cover 220 to engage or disengage the first latching member 510. Specifically, the main control circuit may include, for example, a controller such as an MCU, a motor, and other auxiliary components, to complete the automatic opening or closing function of the latching structure 50. The main control circuit here can, for example, adopt a mature circuit technology solution in the prior art, as long as it can realize the automatic opening or closing function of the latching structure, which will not be described in detail here.

[0046] In summary, the cup lid and cup provided in this application utilize a fingerprint recognition structure 60 to identify fingerprints. The main control circuit 70 determines whether to activate the latching structure 50 based on the fingerprint identified by the fingerprint recognition structure 60, thus opening or closing the upper cover 210. When the fingerprint identified by the fingerprint recognition structure 60 matches a pre-stored fingerprint, the upper cover 210 is open, and the positioning member 310 engages with the inner cover 230 under gravity, allowing the inner cover 230 to rotate along with the outer cover 220 and the upper cover 210 to open or close the cup. When the fingerprint identified by the fingerprint recognition structure 60 does not match a pre-stored fingerprint, the upper cover 210 is closed, and the positioning member 310 disengages from the inner cover 230 under the action of the first magnetic suction member 320, preventing the inner cover 230 from rotating along with the outer cover 220 and the upper cover 210. This prevents the inner cover 230 and the cup 10 from being unscrewed, thus preventing users from accidentally using the cup or maliciously adding substances, ensuring their drinking safety.
