Description

Technical Field

[0001] The utility model belongs to the technical field of fingerprint water cup structures, and particularly refers to a fingerprint water cup. Background Art

[0002] As is well known, a water cup is usually a container for people to hold liquids, and can be used to drink tea, water, beverages, etc. usually. Most cups are cylindrical, with an open upper end and hollow inside for holding things. Water cups are particularly important in people's daily lives. As we all know, diseases come in through the mouth. The cup lids of existing water cups can be opened and used by anyone. When others take the wrong water cup to use, or others put poison or other illegal chemical agents in the user's water cup, it is easy to cause the spread of diseases and damage to the user's body. Therefore, there are certain safety hazards when using existing water cups. For this reason, water cups with fingerprint locks have emerged on the market, and the cup lid can only be opened for drinking after fingerprint unlocking.

[0003] For example, in Chinese Patent CN202221849254.7, a fingerprint water cup that can be quickly opened and has a child lock function includes a cup body and a cup lid. The cup lid is provided with a movable lid and a drinking port. The inner cavity of the cup lid is provided with a driver, a push rod, and a driven rod. The driver drives the push rod to slide through a transmission mechanism. One end of the push rod is provided with a lock tongue part, and the other end is provided with a first rack. One end of the driven rod is provided with a second rack, and the other end is provided with a lock tongue part. A driven gear is installed between the first rack and the second rack. The movable lid is provided with a buckle position that overlaps with the lock tongue part. A control board, a battery, and a fingerprint module are installed in the cup lid. The user can quickly unlock the movable lid through the fingerprint module with a single finger for drinking. However, this product also has certain deficiencies: electrical components are arranged in the main body of the cup lid, and the sealing requirements of the main body of the cup lid are high. Once the sealing is not done well, the electrical components are easily damaged by water ingress; the cup lid is locked through a bolt structure and thus cannot be rotated and opened. Once the user forcibly rotates or accidentally rotates it, the bolt is easily damaged, thus affecting the transmission structure. Summary of the Invention

[0004] The purpose of the utility model is to provide a safe and stable fingerprint water cup.

[0005] The purpose of the utility model is achieved as follows:

[0006] A fingerprint water cup includes a cup lid and a cup body that are threadedly connected to each other. The cup lid includes a cup lid body and a flip lid that are hinged to each other. A drinking port or a straw port for installing a straw is arranged on the cup lid body; a button and an elastic member are arranged on the cup lid body. The flip lid is provided with a slot that cooperates with the hook of the button, and the elastic member gives the hook of the button a force to bite on the slot; when the button is pressed, the flip lid can be opened from the cup lid body; the cup lid body includes an inner lid and an outer lid that are rotatably connected to each other, and the inner lid is threadedly connected to the cup body; when the cup lid is threadedly connected to the cup body, the outer lid covers the outside of the inner lid.

[0007] A chamber is formed between the inner cover and the outer cover. A locking member that moves along the guiding ribs is arranged in the chamber, and an elastic member is arranged in the chamber. The elastic member pushes the locking member and connects the inner cover and the outer cover, and at the same time, the inner cover and the outer cover can rotate synchronously; by driving the pushing part of the locking member, the locking member moves, the inner cover and the outer cover lose connection, and when the outer cover is rotated, the inner cover does not rotate accordingly. At the same time, the locking member abuts against the rear part of the button, and the button cannot be driven;

[0008] A pushing member is arranged at the lower end of the flip cover. The pushing member is driven by a motor inside the flip cover, and the pushing member rotates and can push the pushing part of the locking member to move;

[0009] A storage battery, a control circuit board and a fingerprint module are arranged inside the flip cover; the storage battery supplies power to electrical components, the control circuit board is electrically connected to the fingerprint module and the motor; when the fingerprint module is triggered, the control circuit board controls the motor to rotate.

[0010] Guiding ribs are arranged on the outer cover. The locking member is affected by the guiding ribs and can slide along the guiding ribs; a biting part is arranged on the locking member, a matching part is arranged on the inner cover, and the elastic member gives a force for the biting part to be clamped on the matching part.

[0011] The biting part is a tooth part, and the matching part is an annular tooth. When the tooth part bites on the annular tooth, the inner cover and the outer cover are connected to each other.

[0012] The inner cover includes a first shell and a second shell that are fixedly connected to each other. A drinking port is arranged in the middle of the first shell, and a sealing ring connected to the cup body is arranged at the lower end of the first shell. The drinking port passes through the second shell and the outer cover and is exposed; the annular tooth is arranged on the second shell, a perforation is formed in the middle of the locking member, the perforation is sleeved outside the annular tooth, and the tooth part is arranged on the inner side of the perforation.

[0013] The outer cover is provided with a notch, and the pushing part of the locking member passes through the cup cover body and moves in the notch.

[0014] The pushing part is a column integrally formed on the locking member.

[0015] The pushing member has a pushing convex edge and a holding concave part. When the pushing member rotates, the pushing convex edge of the pushing member can drive the pushing part to move; when the pushing member resets, the pushing part can be located in the holding concave part and wait for the pushing convex edge to drive; an arc-shaped wall is formed between the pushing convex edge and the holding concave part.

[0016] When the pushing member is held in the extreme pushing state, the pushing direction formed by the center position of the rotation axis of the pushing member and the position where the pushing convex edge abuts against the pushing part is parallel to the moving direction of the locking member.

[0017] A magnet is provided inside the cup lid body, and a magnetic induction switch is provided inside the flip cover; when the flip cover covers the cup lid body, the magnet can give a signal to the magnetic induction switch.

[0018] The output shaft of the motor is directly connected to the pushing member; alternatively, a gear set or a bevel gear set is provided on the output shaft of the motor, and the output teeth of the gear set or the bevel gear set are connected to the pushing member.

[0019] The prominent and beneficial technical effects of the present utility model compared with the prior art are as follows:

[0020] 1. The present utility model adopts the method of mutual rotation of the inner cover and the outer cover. Only when the inner cover and the outer cover are connected by the locking member, when the outer cover covering the outside of the inner cover is rotated, the inner cover can rotate synchronously, so that the cup lid can be removed from or installed on the cup body. When in the locked state: the pushing member moves forward under the drive of the motor and moves the locking member to the rear of the button, and the engaging part of the locking member and the mating part of the inner cover are separated; in this state, the user cannot press the button, and when the outer cover is rotated, the inner cover does not rotate, and the cup lid cannot be removed from the cup body. When in the unlocked state; the user unlocks by fingerprint, the pushing member moves backward under the drive of the motor, the locking member resets under the action of the elastic member, the pushing member moves away from the button, and the engaging part of the locking member and the mating part of the inner cover are engaged; in this state, the user can either press the button to open the flip cover for drinking water or rotate the outer cover to remove the cup lid from the cup body. When the user wants to drink water, two procedures are required. The first step is to unlock by fingerprint, and the second step is to press the button to open the flip cover. The sequential operations effectively avoid misoperation by the user.

[0021] 2. The present utility model installs the electrical components inside the flip cover, and the pushing member is driven by rotation. The rotating shaft is the part that is most easily sealed and can be effectively sealed. Therefore, the flip cover can be effectively sealed by means of a sealing ring or tight fitting, etc., to prevent liquid from entering the flip cover. The flip cover itself is not easily in contact with liquid, and effective sealing can also be achieved, thus ensuring the structural stability.

[0022] 3. In the present utility model, the engaging part is a tooth part, and the mating part is an annular tooth. When the tooth part engages on the annular tooth, the inner cover and the outer cover are connected to each other. Through this mechanism, the inner cover and the outer cover can be effectively connected by the locking member regardless of any rotational position.

[0023] 4. In the present utility model, when the pushing member is in the extreme pushing state, the pushing direction formed by the center position of the pushing member rotating shaft and the position where the pushing convex edge abuts against the pushing part is parallel to the moving direction of the locking member. In this state, the pushing member is in a dead point state, and when the user presses the button, the backward push of the button will not cause the pushing member to rotate.

[0041] The following further describes the present utility model with specific embodiments in conjunction with the accompanying drawings, as shown in Figures 1 - 15 shown:

[0042] A fingerprint water cup, comprising a cup cover and a cup body 1 that are threadedly connected to each other. The cup cover includes a cup cover body 2 and a flip cover 3 that are hinged to each other. A drinking port 223 or a straw port for installing a straw is provided on the cup cover body 2. The water cup can be made into a direct drinking cup or a straw cup, and the specific type of the water cup is determined by the manufacturer itself; if it is made into a direct drinking cup, a plug 33 is provided on the flip cover, and if it is made into a straw cup, a convex rib for pressing the straw is provided on the flip cover. A button 20 and an elastic member are provided on the cup cover body 2. The flip cover 3 is provided with a clamping groove 30 that cooperates with the hook 201 of the button. The elastic member gives the hook 201 of the button a force to bite on the clamping groove 30; when the button 20 is pressed, the flip cover 3 can be opened from the cup cover body 2; the cup cover body 2 includes an inner cover 22 and an outer cover 21 that are rotatably connected to each other. The inner cover 22 is threadedly connected to the cup body 1; in the state where the cup cover is threadedly connected to the cup body, the outer cover 21 covers the outside of the inner cover 22; the rotation mode of the inner cover 22 and the outer cover 21 can adopt the following methods: an annular groove is provided on the inner cover, and a convex edge that cooperates with the annular groove is provided on the outer cover; alternatively, an annular groove is provided on the outer cover, and a convex edge that cooperates with the annular groove is provided on the inner cover.

[0043] A chamber is formed between the inner cover 22 and the outer cover 21. A locking member 4 that moves along the guiding ribs is arranged in the chamber. An elastic member is arranged in the chamber. The elastic member pushes the locking member 4 and connects the locking member 4 to the inner cover 22 and the outer cover 21. At the same time, the inner cover 22 and the outer cover 21 can rotate synchronously. The pushing part 41 of the locking member is driven so that the locking member 4 moves. The inner cover 22 and the outer cover 21 lose connection. When the outer cover 21 is rotated, the inner cover 22 does not rotate accordingly. At the same time, the locking member 4 abuts against the rear part of the button 20, and the button 20 cannot be pushed. The elastic member is preferably a component such as a spring 19 or soft rubber. By using the locking member to limit the button and the inner and outer covers at the same time, the structure is simple. A pushing member 61 is arranged at the lower end of the flip cover. The pushing member 61 is driven by a motor 6 in the flip cover 3. The pushing member 61 rotates and can push the pushing part 41 of the locking member to move. A storage battery 7, a control circuit board 8 and a fingerprint module 5 are arranged in the flip cover 3. The fingerprint module 5 is preferably installed above the flip cover 3 and protected by a protection board. The user can touch the touch part 51 to unlock. The storage battery 7 supplies power to the electrical components. The control circuit board 7 is electrically connected to the fingerprint module 5 and the motor 6. When the fingerprint module 5 is triggered, the control circuit board 7 controls the motor 6 to rotate. As Figures 6 - 8 shown, when in the locked state: the pushing member moves forward under the drive of the motor and moves the locking member to the rear of the button, and the engaging part of the locking member and the mating part of the inner cover are separated; in this state, the user cannot press the button, and when the outer cover is rotated, the inner cover does not rotate, and the cup cover cannot be removed from the cup body. As Figures 3 - 5 shown, when in the unlocked state; the user unlocks by fingerprint. The pushing member moves backward under the drive of the motor. The locking member resets under the action of the elastic member. The pushing member moves away from the button, and the engaging part of the locking member and the mating part of the inner cover are engaged; in this state, the user can either press the button to open the flip cover for drinking water or rotate the outer cover to remove the cup cover from the cup body. When the user wants to drink water, two procedures are required. The first step is to unlock by fingerprint, and the second step is to press the button to open the flip cover. The sequential operations effectively avoid misoperation by the user.

[0044] Guiding ribs 212 are arranged on the outer cover 21. The locking member 4 is affected by the guiding ribs 212 and can slide relying on the guiding ribs 212. An engaging part is arranged on the locking member 4, and a mating part is arranged on the inner cover 22. The elastic member gives a force for the engaging part to be clamped on the mating part. The engaging part is a tooth part 43, and the mating part is an annular tooth 2211. When the tooth part 43 is engaged with the annular tooth 2211, the inner cover 22 and the outer cover 21 are connected to each other. Through this mechanism, no matter at any rotational position, the locking member 4 can effectively connect the inner cover and the outer cover.

[0045] The inner cover 22 includes a first housing 222 and a second housing 221 that are fixedly connected to each other. The first housing 222 and the second housing 221 can be connected by snap-fastening or by screw fixation. The specific method is selected by the manufacturer according to the actual situation. A drinking port 223 is provided in the middle of the first housing 222, and a sealing ring 29 for connecting with the cup body is provided at the lower end of the first housing. The drinking port 223 passes through the second housing 221 and the outer cover 221 and is exposed. When the user drinks water, the liquid directly drains from the drinking port of the first housing, and the liquid does not contact the second housing and other components, effectively avoiding the problem of water leakage. The sealing ring of the first housing seals the mouth of the cup body. The second housing 221 is provided with the annular teeth 2211. The middle part of the locking member 4 has a through hole 42, and the through hole 42 is sleeved outside the annular teeth 2211. The tooth part 43 is provided on the inner side of the through hole. With this structure, the tooth part of the locking member always remains outside the annular teeth, ensuring the stability of the process of the tooth part engaging with the annular teeth.

[0046] The outer cover 21 is provided with a notch 211, and the pushing part 41 of the locking member passes through the cup cover body 2 and moves in the notch 211. The notch 211 is used to assist in limiting the locking member, making the movement of the locking member stable. Preferably, the pushing part 41 is a column integrally formed on the locking member 4. The outer surface of the column is round, which is beneficial for the pusher to push.

[0047] The pusher 61 has a pushing flange 612 and a holding recess 613. When the pusher 61 rotates, the pushing flange 612 of the pusher can drive the pushing part 41 to move; when the pusher 61 resets, the pushing part 41 can be located in the holding recess 613 and wait to be driven by the pushing flange 612. An arc-shaped wall is formed between the pushing flange 612 and the holding recess 613. When the pusher 61 rotates, the pushing part will move under the action of the arc-shaped wall until it abuts against the end of the pushing flange. The holding recess cooperates with the pushing part to prevent the pushing part and the pusher from being misaligned. Preferably, the flip cover is provided with a position for limiting the position of the pusher and a recess 311 for the pusher, so that the pusher 61 and the pushing part 41 are limited in the recess 311, making the structure more stable.

[0048] When the pusher 61 is in the extreme pushing state, the pushing direction formed by the center position of the rotation axis of the pusher and the position where the pushing flange abuts against the pushing part is parallel to the moving direction of the locking member. In this state, the pusher is in a dead point state. When the user presses the button, the backward push of the button will not cause the pusher to rotate.

[0049] A magnet 39 is provided inside the cup lid body 2, and a magnetic induction switch is provided inside the flip cover. When the flip cover covers the cup lid body, the magnet can give a signal to the magnetic induction switch. In this way, it is determined whether the flip cover covers the cup lid body. Preferably, the magnetic induction switch is a part of the control circuit board. The magnet can be clamped at any position inside the cup lid body, preferably below the magnetic induction switch, which is beneficial to improving the induction accuracy.

[0050] The output shaft of the motor is directly connected to the pushing member; alternatively, a gear set or a bevel gear set is provided on the output shaft of the motor, and the output gear of the gear set or the bevel gear set is connected to the pushing member. The motor can directly drive the pushing member to rotate or indirectly drive the pushing member to rotate through the gear set. As Figure 11 shown, a second bevel gear 63 is fixed on the output shaft of the motor, the pushing member 61 is connected to the first bevel gear 62, and the first bevel gear 62 and the second bevel gear 63 are meshed. The gear set can be a common gear set in addition to the bevel gear set.

[0051] This application will necessarily involve a control circuit, and the circuit control part is not the key point of protection of this utility model. The manufacturer can let an external cooperation manufacturer produce the control circuit board and its accessories according to the installation size and requirements of its own cup lid, and then assemble them. Obtaining signals through the fingerprint module and making the motor rotate forward and backward, or driving the motor to rotate in a delayed manner, etc. are all conventional technical means in the art. A magnetic suction charging port 9 can also be provided on the cup lid to charge the storage battery by magnetic suction.

[0052] The above embodiments are only the preferred embodiments of this utility model, and do not limit the protection scope of this utility model accordingly. Therefore, all equivalent changes made according to the structure, shape, and principle of this utility model should be covered within the protection scope of this utility model.
