Description

Technical Field

[0001] The utility model relates to the technical field of water cups, in particular to a safety water cup that can be unlocked and opened with fingerprints. Background Art

[0002] Cups with lids are a major branch of the cup family. Most of the time, users tighten the lids to prevent water from spilling and facilitate carrying. They unscrew the lids when they need to drink water. However, when the user goes out, the cup will move up and down or even be squeezed as the user walks, runs, jumps, etc. The lid is only connected to the cup body by a threaded structure, and it is common for it to loosen or even spill water, causing unnecessary trouble to the user during use. In addition, if the lid is unscrewed by someone other than the user without the user's knowledge, such as accidentally unscrewed by a child, the child may be scalded by the hot water in the cup. If it is unscrewed by a stranger or even thrown into an unknown object, it is more likely to cause great harm to the user's personal safety. Based on this situation, how to avoid the accidental loosening of the lid after it is tightened or even accidentally unscrewed by someone other than the user, and improve the safety of the use of water cups, is becoming an increasingly urgent problem that relevant technical personnel need to solve.

A slider is provided, and a dynamic locking block is slidably provided on the moving route of the slider, an external spring is provided between the slider and the dynamic locking block, two ends of the external spring are respectively fixedly connected with the slider and the dynamic locking block, a first through opening is provided through corresponding positions of the middle cover and the dynamic locking block, the positions of the dynamic locking block and the fixed locking block correspond, a positioning plate is fixedly provided inside the middle cover, a mainboard and a lithium battery are fixedly provided on the upper part of the positioning plate, a fixing plate is fixedly provided on the upper part of the mainboard, a fingerprint module is fixedly provided on the upper part of the fixing plate, and the lithium battery and the fingerprint module are both electrically connected to the mainboard.

[0005] Furthermore, a motor is arranged inside the middle cover, a worm is fixedly arranged at the end of the output shaft of the motor, a worm wheel is rotatably arranged inside the middle cover, the worm wheel is meshingly connected with the worm, a gear is coaxially fixed below the worm wheel, a rack is arranged on one side of the slider close to the gear, the rack is meshingly connected with the gear, and the number of teeth on the rack is 3 groups.

[0006] Furthermore, an inner spring is arranged inside the slider, and two ends of the inner spring are respectively fixedly connected to the slider and the middle cover, and the expansion and contraction direction of the inner spring is parallel to the moving direction of the slider.

[0007] Furthermore, a fixed shaft is arranged inside the middle cover, and the number of the fixed shafts is 2 groups, and the 2 groups of fixed shafts are respectively located on both sides of the slider, a first rotating block is arranged on one side of the slider, and a second rotating block is arranged on the other side of the slider, and the first rotating block and the second rotating block are respectively rotatably connected with the corresponding fixed shafts. Taking the top view angle as a reference, a first V-shaped spring is arranged in the clockwise direction of the first rotating block, and a second V-shaped spring is arranged in the clockwise direction of the second rotating block, the first V-shaped spring maintains elastic contact with the first rotating block, and the second V-shaped spring maintains elastic contact with the second rotating block, and a second through opening is arranged through the corresponding positions of the middle cover and the first rotating block and the second rotating block, and the first rotating block and the second rotating block both correspond to the positions of the locking block.

[0008] Furthermore, taking the top-down angle as a reference, the distance between the locking block on one side close to the center position of the middle cover and the center position of the middle cover gradually increases in the clockwise direction, and the shape of the first rotating block and the second rotating block is the shape of a "comma" in Chinese. On this basis, the first rotating block and the second rotating block have an "outer convex side" and an "inner concave side". In a stationary state, the outer convex sides of the first rotating block and the second rotating block are in contact with the side of the locking block close to the center position of the middle cover, and the tails of the first rotating block and the second rotating block extend between the locking blocks.

[0009] Furthermore, the positioning plate is located above the slider, and a display screen and a charging port are fixedly arranged on the upper part of the fixed plate.

[0010] The beneficial effects of the fingerprint unlocking and opening safety water cup of the utility model are as follows:

[0011] 1. If the fingerprint recognition is passed, the dynamic lock block extends and plugs into the gap of the fixed lock block. The user only needs to twist the upper cover counterclockwise to gradually separate the upper cover, middle cover and lower cover from the cup body as a whole. If the fingerprint recognition is not passed, the dynamic lock block remains stationary. Even if the upper cover is twisted counterclockwise, it can only be idle. Twisting the upper cover clockwise can only make the lower cover and the cup body more tightly combined, thereby effectively avoiding the accidental loosening of the cup cover after tightening or even being accidentally unscrewed by people other than the user, effectively improving the safety of the water cup;

[0012] 2. The connection between the card block and the card hole provides a good structural basis for the upper cover and the middle cover to rotate as a whole by twisting the upper cover. The fingerprint module, the main board, and the lithium battery provide a good structural basis for whether the motor works and whether the dynamic lock block extends. The convex sides of the first rotating block and the second rotating block are in contact with the side of the fixed lock block close to the center of the middle cover. The design of the sliding connection between the card strip and the card slot provides a good structural basis for the upper cover and the middle cover to rotate relative to the lower cover as a whole when the fingerprint recognition fails and the upper cover is twisted counterclockwise. The tails of the first rotating block and the second rotating block extend between the fixed lock blocks, which provides a good structural basis for the upper cover, the middle cover, and the lower cover to be more tightly combined with the cup body as a whole when the upper cover is twisted clockwise;

[0013] 3. The design of three groups of rack teeth effectively avoids the continuous movement of the slider caused by the unnecessary rotation of the output shaft of the motor due to inertia. Regardless of whether the slider is in the extended state or the retracted state, the inner spring can keep the rack in contact with the gear, so that the slider can respond to the start of the motor in time, thereby effectively ensuring the precise movement of the dynamic locking block in time. When the dynamic locking block fails to be accurately inserted between the fixed locking blocks and collides with the fixed locking blocks, the outer spring can effectively buffer the impact. The design of the distance between the side of the fixed locking block close to the center position of the middle cover and the center position of the middle cover gradually increases in the clockwise direction, so that the user only needs to continuously twist the upper cover counterclockwise to achieve fine-tuning of the middle cover and then accurately insert the dynamic locking block again between the fixed locking blocks, thereby effectively ensuring the fault tolerance space of the dynamic locking block in the spatial position.

[0032] The working principle of the fingerprint unlocking and opening safety water cup of the utility model is as follows: in the default state, the lower cover 8 is tightened to the upper part of the cup body 2 through the thread 9. When the user wants to drink water, he presses the tip of his finger on the pressing position of the fingerprint module 7. The fingerprint module 7 recognizes successfully, and the main board 11 starts the motor 20. The output shaft of the motor 20 drives the worm 23 to rotate, the worm 23 drives the worm wheel 24 to rotate, and the worm wheel 24 drives the gear 22 to rotate synchronously. The gear 22 drives the rack 21, the slider 18, the outer spring 28, and the dynamic lock block 27 as a The whole body moves outward synchronously, and the dynamic locking block 27 extends out from the first opening position and is inserted between the fixed locking blocks 29. At this time, the user twists the upper cover 1 counterclockwise, and the dynamic locking block 27 pushes the fixed locking block 29, so that the upper cover 1, the middle cover 3, and the lower cover 8 can rotate as a whole and gradually separate from the cup body 2. Even if the dynamic locking block 27 is not accurately inserted between the fixed locking blocks 29 at the beginning but touches the fixed locking blocks 29, the user can fine-tune the middle cover 3 in the process of twisting the upper cover 1 counterclockwise so that the dynamic locking block 27 is accurately inserted between the fixed locking blocks 29. After drinking the water, twist the upper cover 1 counterclockwise to close the middle cover 3. The upper cover 1 is moved, and the tails of the first rotating block 16 and the second rotating block 26 are added to push the fixed locking block 29. The upper cover 1, the middle cover 3, and the lower cover 8 are tightly combined with the cup body 2 as a whole. The fingerprint is recognized again, and the output shaft of the motor 20 can be reversed, thereby resetting the dynamic locking block 27. If someone other than the user wants to unscrew the cup cover, the fingerprint module 7 will not recognize the fingerprint, the motor 20 will not start, and the dynamic locking block 27 will not extend. Even if the upper cover 1 is turned counterclockwise, the upper cover 1 and the middle cover 3 can only be idling relative to the lower cover 8 as a whole, and will not The lower cover 8 is separated from the cup body 2. During this process, under the action of the first V-shaped spring 17 and the second V-shaped spring 25, the first rotating block 16 and the second rotating block 26 collide with the locking block 29. Even if the upper cover 1 is turned clockwise, the combination of the lower cover 8 and the cup body 2 will only become tighter and tighter under the push of the first rotating block 16 and the second rotating block 26 on the locking block 29, thereby effectively preventing people other than the user from unscrewing the cup cover, and accidental loosening with lower strength than manual twisting of the upper cover 1 will not occur, effectively ensuring the safety of the use of the water cup.
