Technical Field

[0001] The present invention relates to the technical field of water cups, and in particular to a smart fingerprint cup. Background Art

[0002] With the continuous development of today's society, various harmful substances added to water are emerging in the market. In some occasions, whether the drinking water in the cup is safe after the person leaves has attracted more and more attention. At present, there are various water cups on the market, but few water cups can meet the requirement that only the person can open it. Therefore, a water cup with specific protective measures is needed to meet people's growing needs. Summary of the invention

[0003] The purpose of the present invention is to provide a smart fingerprint cup, which can only be opened and used for drinking through the fingerprint of the cup owner. Once the cup cover is tightened, no one can open it unless it is unlocked through a specific fingerprint. This ensures that the water in the cup is safe to drink even if the cup is away from the person.

[0004] In order to solve the above technical problems, the present invention adopts the following technical solutions:

[0005] The present invention discloses a smart fingerprint cup, comprising a cup body and a cup cover threadedly matched with the cup mouth of the cup body;

[0006] The cup cover comprises an outer cover, a toothed cover and an inner cover, wherein the toothed cover is coaxially mounted inside the outer cover, and a stop structure is provided between the outer wall of the toothed cover near the upper end and the lower inner wall of the outer cover so as to clamp the toothed cover inside the lower part of the outer cover and the rotation of the outer cover cannot drive the rotation of the toothed cover; a toothed platform is provided on the inner end surface of the bottom of the toothed cover, and an outer wall of the toothed cover is provided with an outer thread, which is used in conjunction with the inner thread in the cup mouth of the cup body;

[0007] The inner cover is sleeved inside the toothed cover, the upper end of the inner cover is sealed and clamped with the upper flange under the outer cover, and a clamping groove and a buckle structure are provided between the outer cover and the inner cover to enable the two parts to rotate synchronously, and the rotation of the outer cover can drive the inner cover to rotate;

[0008] The cup cover is provided with a fingerprint intelligent self-locking device, and the fingerprint intelligent self-locking device includes a fingerprint unlocking module, and the fingerprint unlocking module is electrically connected to the master control chip, and the master control chip is electrically connected to a battery and a motor respectively, one end of the motor is connected to a concentric wheel, and an eccentric gear lever is provided on the concentric wheel; the two side walls of the inner cover are symmetrically provided with a tightening cover claw and a loosening cover claw, and the tightening cover claw and the loosening cover claw are both provided with axial holes, and the outer walls on both sides of the inner cover are symmetrically provided with small shafts, and the axial holes of the tightening cover claw and the loosening cover claw are respectively assembled on the small shaft of the outer wall of the inner cover and a torsion spring is installed therebetween, the tightening cover claw is provided with a clamping surface and a slipping surface, and the loosening cover claw is also provided with a clamping surface; the eccentric gear lever passes through a preset track hole on the outer wall of the inner cover to the outside of the inner cover and abuts against the connecting rod of the loosening cover claw.

[0009] Furthermore, the outer cover is assembled by a clamping cover, an outer cover upper part and an outer cover lower part. The clamping cover T-shaped shoulder is pressed against the upper part of the outer cover, and the clamping cover T-shaped lower end is pressed against the sealing ring arranged on the upper end surface of the outer cover lower part to form a seal inside the outer cover.

[0010] Furthermore, a sealing groove is provided at the upper end of the tooth cover, a sealing ring is installed in the sealing groove, and the tooth cover and the lower inner wall of the outer cover are sealed through the sealing ring.

[0011] Furthermore, a clamping ring is mounted on the outer periphery of the tooth cover, and the anti-retraction structure is arranged between the outer wall of the clamping ring and the lower inner wall of the outer cover, which is a anti-retraction barb structure.

[0012] Furthermore, the toothed cover is a barrel-shaped structure.

[0013] Furthermore, the gear platform is a circle of gears evenly spaced around the central axis.

[0014] Furthermore, a sealing strip is provided at the bottom of the toothed cover to achieve sealing between the toothed cover and the inner wall of the cup mouth to prevent water in the cup from leaking out.

[0015] Furthermore, the fingerprint unlocking module includes a fingerprint collector and a fingerprint sensing chip.

[0016] Furthermore, the master control chip is also electrically connected to a temperature sensor, a temperature display, and a wireless charging module (with a matching wireless charging stand) for charging the battery.

[0017] Furthermore, the wireless charging module includes a charging power indicator light.

[0018] Compared with the prior art, the beneficial technical effects of the present invention are:

[0019] When tightening the cup lid, external force twists the outer lid, and the outer lid drives the inner lid to rotate. At this time, the loose lid claw is lifted up under the action of the eccentric gear lever of the motor, and the lower claw is completely separated from the gearing table. The tight lid claw is inserted into the gearing table. As the outer lid drives the inner lid to rotate to tighten, the inner lid drives the tight lid claw to rotate, and the clamping surface of the tight lid claw is pressed against the gearing surface of the gearing table, thereby driving the rotation of the geared lid, realizing the tightening fit of the external thread of the geared lid and the internal thread of the cup mouth.

[0020] When loosening the cup lid, you first need to unlock it with your fingerprint. The master control chip controls the motor to rotate. The action of the motor's eccentric lever cooperates with the torsion spring to lower the loose lid claw. The loose lid claw is inserted into the interval of the gear stage and the card point is pressed against the gear stage to stop the rotation. The outer cover is twisted in the direction of loosening the cup lid to drive the inner cover to rotate. At the same time, due to the anti-rotation effect of the loose lid claw and the gear stage, the inner cover drives the gear cover to rotate at the same time, so that the outer thread of the gear cover is disengaged from the inner thread of the cup mouth, and the cup lid is loosened and separated from the cup body. Within a certain period of time, under the control of the master control chip, the motor will drive the eccentric lever, and the eccentric lever will move the loose lid claw to lift up and reset.

[0021] Wireless charging: The smart fingerprint cup can be charged wirelessly and is equipped with a wireless charging module (that is, it is charged in conjunction with a wireless charging stand, which is a very common technology, coil induction charging). The wireless charging module can charge the battery in the cup cover without being connected by wires.

[0022] The assembly between the outer cover and the inner cover adopts a rotation-stopping structure with multiple blocks and slots, which has a simple structure and is easy to assemble. Moreover, the outer cover drives the inner cover to rotate firmly and stably, and no relative sliding occurs. In the assembly of the outer cover and the toothed cover, the toothed cover can be rotated and clamped in the outer cover through a clamping ring. The clamping ring is provided with a stop barb structure to ensure that the toothed cover will not fall out, and at the same time, it can rotate by itself without being driven by the outer cover, which is not only easy to install but also reliable. The inner cover is an integrated design, while the prior art is a separate component design. The integrated inner cover has a simple structure and saves costs.

[0023] The present invention can ensure the absolute safety of the water quality in the water cup, and no one except the owner of the water cup can open it. The overall structure is simple and compact, easy to operate and has better structural durability. Intelligent control is more convenient and fast, and wireless charging is possible, making charging more convenient and fast. BRIEF DESCRIPTION OF THE DRAWINGS

DETAILED DESCRIPTION

[0041] like Figures 1 to 15 As shown, a smart fingerprint cup includes a cup body 1 and a cup cover, wherein:

[0042] The cup cover comprises an outer cover 2, a toothed cover 3 and an inner cover 4. The outer cover 2 is assembled by a pressing cover 201, an outer cover upper 202 and an outer cover lower 203. The T-shaped shoulder of the pressing cover 201 is pressed against the upper part of the outer cover upper 202, and the T-shaped lower end of the pressing cover 201 presses against the sealing ring arranged on the upper end surface of the outer cover lower 203 to form a seal inside the outer cover.

[0043] The gear cover 3 is coaxially installed inside the outer cover 2. A sealing groove is provided on the outer wall of the upper end of the gear cover 3, and a sealing ring is installed inside. A seal is formed with the lower inner wall of the outer cover 2 through the sealing ring. The clamping ring 5 is mounted on the outer periphery of the gear cover 3 and pressed against the lower part of the sealing groove. A stop structure is provided between the outer wall of the clamping ring 5 and the lower inner wall of the outer cover 2, so that the clamping ring can clamp the gear cover inside the outer cover, and the rotation of the outer cover 2 cannot drive the rotation of the gear cover 3.

[0044] The toothed cover 3 is a barrel-shaped structure, and a toothed platform 301 is provided on the inner end surface of the bottom, and the toothed platform 301 is a circle of teeth evenly spaced around the central axis. The outer wall of the toothed cover 3 is provided with an external thread, which is used in conjunction with the internal thread in the cup mouth of the cup body. A sealing strip is provided at the bottom of the toothed cover 3 to achieve a seal between the toothed cover and the inner wall of the cup mouth to prevent water in the cup from leaking out.

[0045] The inner cover 4 is mounted inside the toothed cover 3, and the upper end of the inner cover 4 is sealed and clamped with the upper flange under the outer cover 2, and a buckle 204 and a slot 401 are provided between the outer cover 2 and the inner cover 4 to enable the two components to rotate synchronously (it should be known in the art that the positions of the slot and the buckle can be interchanged), and the rotation of the outer cover 2 can drive the inner cover 4 to rotate.

[0046] The cup cover is provided with a fingerprint intelligent self-locking device, which includes a fingerprint unlocking module 6 (including: a fingerprint collector 601, a fingerprint sensing chip 602, a fingerprint clamping ring 603, and a fingerprint pressing ring 604). The fingerprint unlocking module 6 is electrically connected to a master control chip 7, and the master control chip 7 is electrically connected to a battery 8 and a motor 9 respectively. One end of the motor 9 is connected to a concentric wheel, and an eccentric gear lever 901 is provided on the concentric wheel; the two side walls of the inner cover 4 are symmetrically provided with a cover tightening claw 10 and a cover loosening claw 11. Both the cover tightening claw and the cover loosening claw are provided with axial holes, and small shafts are symmetrically provided on the outer walls of both sides of the inner cover 4. The axial holes of the cover tightening claw 10 and the cover loosening claw 11 are respectively assembled on the small shafts on the outer wall of the inner cover 4 and a torsion spring 12 is installed between the two; the cover tightening claw 10 is provided with a clamping surface 1001 and a slipping surface 1002, and the cover loosening claw 11 is also provided with a clamping surface; the eccentric gear rod 901 passes through the preset track hole 402 on the outer wall of the inner cover 4 to the outside of the inner cover 4 and abuts against the connecting rod 1101 of the cover loosening claw 11.

[0047] When tightening the cup lid, external force twists the outer cover 2, and the outer cover 2 drives the inner cover 4 to rotate. At this time, the loose cover claw 11 is lifted up under the action of the eccentric gear lever 901 of the motor 9, and the lower claw is completely separated from the gearing platform 301. The tight cover claw 10 is inserted into the gearing platform 301. As the outer cover 2 drives the inner cover 4 to rotate to tighten, the inner cover 4 drives the tight cover claw 10 to rotate, and the clamping surface 1001 of the tight cover claw 10 presses against the gearing surface of the gearing platform 301, thereby driving the rotation of the geared cover 3, realizing the tightening fit between the external thread of the geared cover 3 and the internal thread of the cup mouth.

[0048] When releasing the cup cover, fingerprint unlocking is first required, the master control chip controls the motor to rotate, the eccentric lever 901 of the motor 9 puts down the loose cover card 11 claw, the loose cover claw 11 is inserted into the interval of the gear platform 301 and the card point is pressed against the gear platform to stop the rotation, and the outer cover 2 is twisted in the direction of loosening the cup cover to drive the inner cover 4 to rotate, and at the same time, due to the anti-rotation effect of the loose cover claw 11 and the gear platform 301, the inner cover 4 drives the gear cover 3 to rotate at the same time, so that the external thread of the gear cover 3 is separated from the internal thread of the cup mouth, and the cup cover is loosened and separated from the cup body. Within a certain time (such as 2-10s, preferably 2s, 3s, 4s or 5s), under the control of the master control chip 7, the motor 9 will drive the eccentric lever 901, and the eccentric lever 901 will move the loose cover claw 11 to lift and reset.

[0049] like Figure 8-10 As shown: Figure 8 To tighten the cup cover, the claw is in the clamping state, and the clamping surface of the clamping claw is clamped; the clamping claw of the loose cover is lifted by the motor; Fig. 9 To release the cup cover, the claw is in the clamping state, the slipping surface of the clamping claw of the cover continues to slip, and the clamping claw of the cover release is lowered by the motor and clamped into the gear table; Fig.10 In order to tighten the cup cover again, the clamping claw is in the clamping state, the clamping surface of the clamping claw of the cover is clamped, and the clamping claw of the cover is lifted and reset by the motor in a short time after the cup cover is unscrewed.

[0050] like Fig.11 The left side of the figure shows that the cover release claw 11 is lifted by the motor 9 and is out of the gear stage state. The right side of the figure shows that the cover release claw 11 is lowered by the motor 9 (lowered as the eccentric gear lever rotates under the action of the torsion spring 12) and inserted into the gear stage to enter the clamping state.

[0051] like Fig.12 , is the position state of the tight cover claw 10.

[0052] Electronic control part: The master control chip 7 is installed on the upper part of the inner cover 4. A temperature display 13 is provided on the upper part of the master control chip 7. The temperature display 13 can display the temperature through the clamping cover (with a display window). A wireless charging module is provided inside the clamping cover 201 (i.e., the sealed space inside the outer cover 2). The wireless charging module includes an induction coil 14. A battery 8, a motor 9, and an induction coil adapter board 15 are also installed inside the inner cover 4. The induction coil adapter board 15 is connected to the induction coil 14 to play a rectifying role. A temperature sensor 16 is provided at the bottom of the tooth cover 3 and between the inner cover and the tooth cover. The master control chip 7 is respectively connected to the battery 8, the fingerprint sensor chip 602, the temperature display 13, the induction coil adapter board 15, the motor 9, and the temperature sensor 16. The master control chip 7 performs overall control over all electronic control parts.

[0053] Wireless charging: The smart fingerprint cup can be charged wirelessly and is equipped with a wireless charging stand (a very common technology, coil induction charging). The battery in the cup cover can be charged by placing the cup cover on the wireless charging stand without connecting it through wires. There is a charging power indicator light on the charging stand.

[0054] Those skilled in the art should know that the specific circuit structure and specific control circuit structure of the electronic control part involved in this patent are well-known existing technologies in the field, so they are not described in detail here.

[0055] The embodiments described above are only descriptions of the preferred modes of the present invention, and are not intended to limit the scope of the present invention. Without departing from the design spirit of the present invention, various modifications and improvements made to the technical solutions of the present invention by ordinary technicians in this field should all fall within the protection scope determined by the claims of the present invention.
