[0002] As an essential drinking tool in our daily lives, water bottles are crucial for health, ensuring their safety and hygiene. However, most water bottles currently on the market still lack safety in two key areas: drinking water safety and privacy. Existing water bottles are easily opened, which can lead to unsafe incidents such as malicious objects being thrown into the water, as well as the spread of disease through misuse or cross-use.

[0003] Currently, the safety features of most water bottles on the market primarily focus on the buckle on the lid to prevent accidental opening. However, this design is insufficient to provide adequate safety. For example, some water bottles use a spring-loaded lid structure, which, while still effective, offers limited safety.

[0031] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0032] like Figure 1 and Figure 2As shown, one embodiment of the present invention provides a cup. The cup is, for example, a cup for drinking water, or may be a cup for holding coffee, tea, or other liquids. The cup includes, for example, a cup body 10 and a cup lid 20. The cup body 10 and the cup lid 20 are connected, for example, by a threaded connection. A user can open the cup by unscrewing the cup lid 20.

[0033] The cup can also be, for example, a thermos cup. The cup body 10, for example, further includes an outer cup body 110 and a cup liner 120. The cup liner 120 is arranged 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 insulation material to enhance the insulation effect. The insulation 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.

[0034] Specifically, such as Figures 2 to 5 As shown, the cup cover 20 includes an upper cover 210, an outer cover 220, an inner cover 230 and a positioning structure 30. The outer cover 220 is connected to the upper cover 210, and the upper cover 210 can be in a closed state and an open state relative to the outer cover 220. The inner cover 230 is located on the side of the outer cover 220 away from the upper cover 210 and is connected to the outer cover 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 in the upper cover 210, and the positioning member 310 and the first magnetic member 320 are located on the outer cover 220; the positioning member 310 is connected to the first magnetic member 320, the first magnetic member 320 corresponds to the second magnetic member 330, and is located on the side of the positioning member 310 close to the second magnetic member 330. Among them, when the upper cover 210 is in the open state, the positioning member 310 is clamped on 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 are close to each other and attract each other, and the positioning member 310 moves toward the direction close to the second magnetic member 330 under the drive of the first magnetic member 320 to disengage from the inner cover 230.

[0035] Specifically, the upper cover 210 and the outer cover 220 are rotatably connected, for example, by a pivot hinge, and the upper cover 210 is rotated to switch between the closed and open states. The second magnetic member 330 and the first magnetic member 320 are, for example, magnets with opposite magnetic poles near 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, or alloys thereof.

[0036] Further, such as Figure 3 and Figure 5As shown, the inner sidewall of the outer cover 220 is provided with, for example, a circular groove 223, and the outer sidewall of the inner cover 230 is provided with, for example, a circular protrusion 232, which is embedded in the circular groove 223. When the upper cover 210 is in the closed state, the user rotates the cup cover, and the circular groove 223 of the outer cover 220 slides outside the circular protrusion 232, causing the outer cover 220 to slide relative to the inner cover 230, making it impossible to unscrew the inner cover 230 and the cup body 10.

[0037] like Figure 2 As shown, when the upper cover 210 is in a closed state relative to the outer cover 220, due to the mutual attraction between the ends of the first magnetic member 320 and the second magnetic member 330, the first magnetic member 320 is subjected to the magnetic force of attraction between the first magnetic member 320 and the second magnetic member 330 and moves in a direction close to the second magnetic member 330. The first magnetic member 320 is fixed to the positioning member 310, and the first magnetic member 320 drives the positioning member 310 to move in a direction close to the second magnetic member 330, so that the positioning member 310 is disengaged from the inner cover 230, and the inner cover 230 and the outer cover 220 are in an uncoupled state. At this time, when the user rotates the cup cover 20, only the upper cover 210 and the outer cover 220 can rotate together, and the inner cover 230 will not rotate with the outer cover 220, so that the user cannot unscrew the inner cover 230 and the cup body 10, preventing the cup from being easily opened and used or maliciously thrown objects, thereby improving safety and privacy and preventing the spread of disease.

[0038] like Figure 3 As shown, when the upper cover 210 is in an open state relative to the outer cover 220, the first magnetic member 320 is no longer affected by the gravitational force between it and the second magnetic member 330 and moves. Due to the action of gravity, the first magnetic member 320 and the positioning member 310 move toward the inner cover 230, so that the positioning member 310 is engaged with the inner cover 230, and the inner cover 230 and the outer cover 220 are in a locked state. When the user rotates the cup cover 20, the inner cover 230 rotates together with the outer cover 220 and the upper cover 210 to open or tighten the cup cover 20, allowing the user to fill the cup body 10 with liquid, wash the cup, or drink water, etc.

[0039] like Figure 8 、 Figures 9 and 10As shown, 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. A plurality of limiting protrusions 40 are provided at the bottom of the receiving groove 231. The plurality of limiting protrusions 40 are spaced apart to form a plurality of limiting gaps 410. When the upper cover 210 is in the open state, the first magnetic member 320 is no longer subject to the gravitational force between it and the second magnetic member 330. The first magnetic member 320 moves toward the bottom of the receiving groove 231 under the action of gravity, causing the positioning block 311 to be embedded in one of the plurality of limiting gaps 410, and the positioning member 310 is engaged 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 toward the upper cover 210, causing the positioning block 311 to leave the limiting gap 410, and the positioning member 310 is released from the limiting protrusion 40.

[0040] Furthermore, the positioning block 311 is provided with a first inclined surface 313 at one end near the inner cover 230, and the plurality of limiting protrusions 40 are respectively provided with a plurality of second inclined surfaces 420 at one end near the top of the receiving groove 231. The first inclined surfaces 313 and the second inclined surfaces 420 correspond one to one. When the upper cover 210 is opened, the positioning member 310 moves due to the action of gravity, and the first inclined surface 313 slides onto the second inclined surface 420. The relative angles and shapes of the inclined surfaces ensure a smooth docking of the positioning members 310 and reduce friction and resistance when the positioning member 310 moves and inserts into the limiting gap 410, allowing the positioning member 310 to smoothly insert into the limiting gap 410.

[0041] 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 spaced apart from each other. A positioning space 312 is formed between the first positioning block 3111 and the second positioning block 3112. When the upper cover 210 is in the open position, the positioning member 310 moves to engage the inner cover 230. When one of the plurality of limiting protrusions 40 is positioned in the positioning space 312, the first positioning block 3111 and the second positioning block 3112 are respectively positioned in any one of the plurality of limiting gaps 410, thereby enhancing the stability of the engagement between the positioning member 310 and the inner cover 230.

[0042] Furthermore, the positioning member 310 is provided with a positioning sleeve 314, for example, and an opening is provided at one end of the positioning sleeve 314 facing the outer cover 220. The first magnetic member 320 is located in the positioning sleeve 314, and the positioning block 311 is provided on the side wall of the positioning sleeve 314 close to the inner cover 230.

[0043] like Figure 6 and Figure 7As shown, in one embodiment, the outer cover 220 has a positioning post 221 on a side adjacent to the inner cover 230. A through-hole 2211 is provided in the positioning post 221. An opening 2212 is provided on the sidewall of the positioning post 221. The opening 2212 communicates with the through-hole 2211. The positioning member 310 is connected to the through-hole 2211 and is located at one end of the through-hole 2211 adjacent to the inner cover 230. The positioning block 311 extends from the positioning post 221 through the opening 2212. The positioning post 221 provides a movement guide for the positioning member 310 and the first magnetic member 320, ensuring that the positioning member 310 and the first magnetic member 320 are correctly positioned 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 in the receiving groove. When the upper cover 210 is in the closed state and the outer cover 220 is rotated, the positioning post 221 rotates with the outer cover 220 in the receiving groove 231. The end of the positioning post 221 closest to 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, thereby ensuring the use effect of the cup cover 20.

[0044] Furthermore, the cup cover 20 further includes a mounting plate 222, which is connected to the outer cover 220 and covers one end of the through hole 2211 near the inner cover 230. This ensures that the positioning structure 30 can be located in the positioning column 221 and will not fall out of the positioning column 221 during use.

[0045] 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 second magnetic member 330, that is, the first magnetic member 320 drives the positioning member 310 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 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 or may not be consistent. When the upper cover 210 is opened, the positioning member 310 moves so that the bottom end of the positioning member 310 contacts the inner cover 230. When the upper 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 plurality of 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 aforementioned maximum gap is greater than the maximum height, it is ensured that the positioning block 311 can completely disengage from the limiting protrusions 40, ensuring that when the upper cover 210 is closed, the positioning block 311 will not be located in the limiting gap 410, the limiting protrusion 40 will not be located in the positioning space 312, and the inner cover 230 will not rotate together with the outer cover 220.

[0046] like Figure 2 and Figure 3 As shown, in one embodiment, the cup cover 20 further includes a snap structure 50, which includes a first snap member 510 and a second snap member 520. The first snap member 510 is disposed inside the upper cover 210 and is located on a side of the upper cover 210 close to the outer cover 220; the second snap member 520 is disposed on the outer cover 220 and is located on a side of the outer cover 220 close to the upper cover 210. The second snap member 520 corresponds to and matches the first snap member 510. The upper cover 210 can be opened or closed by rotating the first snap member 510 or the second snap member 520. When the user needs to close the upper cover 210, the downward pressure of the upper cover 210 causes the first snap member 510 to press the second snap member 520, and ultimately causes the first snap member 510 to engage with the second snap member 520.

[0047] like Figure 12As shown, in one embodiment, the cup cover 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 buckle structure 50. The fingerprint recognition structure 60 and the main control circuit 70 are arranged inside the upper cover 210 or the outer cover 220, and the fingerprint recognition structure 60 is partially exposed outside the upper cover 210 or the outer cover 220. When the user needs to unlock the cup, the user places his finger on the fingerprint recognition structure 60, and the fingerprint recognition structure recognizes the fingerprint of the person opening the cover. The main control circuit 70 decides whether to drive the control device to control the action of the buckle structure 50 based on the fingerprint recognized by the fingerprint recognition structure 60. If the fingerprint is determined to be the same as the cup holder's fingerprint, the main control circuit 70 drives the control device to control the buckle structure 50 to open, and the user can use the cup and rotate the cup cover 20 normally; if the fingerprint is determined to be different from the cup holder's fingerprint, the buckle 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 in the unfastened state, and the cup body 10 cannot be opened even if the cup cover 20 is rotated. Figure 1 The fingerprint recognition structure 60 and the main control circuit 70 are located inside the upper cover 210, and a portion of the fingerprint recognition structure 60 is 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 inside the upper cover 210 to engage or disengage the second latch 520. 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 latch 520, and controls the second latch 520 to rotate on the outer cover 220 to engage or disengage the first latch 510. Specifically, the main control circuit includes, for example, a controller such as an MCU, a motor, and other auxiliary components, which together complete the automatic opening or automatic closing function of the latch structure 50. The main control circuit here can adopt, for example, mature circuit technology solutions in the prior art, as long as it can achieve the automatic opening or closing function of the latch structure, and will not be described in detail here.

[0048] In summary, the cup lid and cup provided by the present invention utilize a fingerprint recognition structure 60 to recognize a fingerprint. The main control circuit 70 determines whether to actuate the latch structure 50 to open or close the upper cover 210 based on the fingerprint recognized by the fingerprint recognition structure 60. When the fingerprint recognized by the fingerprint recognition structure 60 matches a pre-stored fingerprint, the upper cover 210 is in the open state, and the positioning member 310 is engaged with the inner cover 230 under the action of 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 body. When the fingerprint recognized by the fingerprint recognition structure 60 does not match a pre-stored fingerprint, the upper cover 210 is in the closed state, and the positioning member 310 is disengaged from the inner cover 230 under the action of the first magnetic member 320, preventing the inner cover 230 from rotating along with the outer cover 220 and the upper cover 210. In other words, the inner cover 230 and the cup body 10 cannot be unscrewed, thereby preventing users from misusing the cup or maliciously throwing objects into the cup, thereby ensuring their own drinking water safety.
