Description

Technical Field

[0001] The present invention relates to the technical field of NFC sensing chip protection, and in particular to a protection structure and method based on an NFC bottle bottom sensing chip. Background Art

[0002] NFC, or Near Field Communication, is a short-range, high-frequency wireless communication technology that allows contactless point-to-point data transmission and exchange between electronic devices within a few centimeters, enabling convenient payment, data transmission, identity recognition and other functions.

[0003] With the rapid development of science and technology, the application scope of NFC sensing chips continues to expand, from daily mobile payments to convenient unlocking of smart door locks, and has penetrated into every corner of life. As an indispensable item in people's lives, water bottles are also used in a wide range of scenarios, whether it is outdoor sports, office study, or daily travel.

[0004] However, most of the water bottles on the market currently have relatively simple functions and can often only meet basic water storage and drinking needs. Their functionality is poor, and it is often difficult to view detailed and intuitive real-time data on water temperature and water intake, as well as healthy drinking reminders. Users often do not have an ideal experience when using them.

[0005] Moreover, when the device is used, the bottom of the existing water bottle often lacks a certain protective structure. When the NFC sensing chip is directly installed on the bottom of the water bottle, the NFC sensing chip is often damaged due to the lack of certain protective components. For example, when the existing water bottle is in use, its bottom is supported only by the bottom of the water bottle. However, once the height of the water bottle is high, it is very easy to cause the water bottle to topple over due to the collision of external forces. Once the water bottle topples over, it is very easy to fall from the table, thereby causing damage to the water bottle and the NFC sensing chip at the bottom of the water bottle, which undoubtedly causes great trouble in actual use; Secondly, when the NFC sensing chip is directly installed at the bottom of the water bottle, it often lacks certain shielding and sealing components, which results in the NFC sensing chip being directly exposed to the outside when not in use. This makes it very easy to affect the NFC sensing chip when used in some environments with strong electromagnetic interference. In addition, there is also a risk of demagnetization in the process of carrying the NFC sensing chip. When the NFC sensing chip is close to a strong magnetic field source, such as a magnet, induction cooker, etc., it may cause the magnetic material in the chip to be disordered, resulting in demagnetization, causing the NFC function to be unable to be used normally. In addition, when the water bottle falls accidentally, when a sharp object hits the NFC sensing chip, it is also very easy to damage the NFC sensing chip, which undoubtedly brings great trouble to actual use. Summary of the Invention

An installation cylinder is fixedly connected to the bottom of the bottle body, an NFC induction chip is arranged inside the installation cylinder, a fixing seat is fixedly sleeved on the circumferential outer wall of the end of the installation cylinder, and an anti-slip pad is connected to the outer wall of the fixing seat.

[0007] Preferably, a rubber sleeve is sleeved on the circumferential outer wall of the rotating ring, and a limiting threaded rod is threadedly sleeved on the outer wall of the rubber sleeve. The limiting threaded rod is matched with the limiting groove.

[0008] Preferably, arc-shaped plates are connected to the ends of the plurality of connecting rods, and rubber pads are connected to the outer walls of the arc-shaped plates.

[0009] Preferably, a through sliding groove is provided on the outer wall of the fixing seat, the through sliding groove is cross-shaped, the installation cylinder penetrates through the outer wall of the rotating disk, and the circumferential outer wall of the end of the installation cylinder is fixedly connected to the central inner wall of the through sliding groove.

[0010] Preferably, the plurality of connecting columns respectively pass through the through sliding groove and are fixedly connected to the side walls of the plurality of sealed electromagnetic shielding plates, and rubber sealing gaskets are arranged on the outer walls of the plurality of sealed electromagnetic shielding plates.

[0011] Preferably, a guiding groove is provided on the rear outer wall of the fixing seat, and the plurality of guiding grooves are matched with the connecting rods.

[0012] Preferably, a rubber buffer sleeve is adhered to the inner wall of the installation cylinder, the NFC induction chip is installed inside the rubber buffer sleeve, and a cover plate is threadedly sleeved on the end of the installation cylinder.

[0013] Preferably, a glass plate is hermetically connected to the inner wall of the cover plate by sealant, and a rubber sealing ring is further arranged on the outer wall of the cover plate.

[0014] Preferably, a lifting handle is rotatably connected to the circumferential outside of the bottle body, and a sealing cover is threadedly sealed to the bottle mouth of the bottle body.

[0015] A protection method based on an NFC bottle bottom induction chip, and its usage method steps are as follows: S1: Installation of NFC induction chip: Install the NFC induction chip in the rubber buffer sleeve inside the installation cylinder. The rubber buffer sleeve plays a preliminary buffer and protection role to reduce the impact of vibrations, etc. on the chip. Threadedly connect a cover plate to the end of the installation cylinder, and use sealant to seal and connect a glass plate to the inner wall of the cover plate. At the same time, set a rubber sealing ring on the outer wall of the cover plate to achieve sealed protection of the NFC induction chip inside the installation cylinder without affecting its use, preventing moisture, dust, etc. from entering. And when the NFC induction chip needs to be replaced, the cover plate can be directly disassembled by threading, which is convenient for replacing and repairing the NFC induction chip.

[0016] S2: Placement and stability support: During use, the outer wall of the circumference of one end of the installation cylinder is fixedly connected to the inner wall of the center of the through sliding groove, and the other end of the installation cylinder is fixedly connected to the bottom of the bottle body, providing support for the subsequent structure. An anti-slip pad is installed on the outer wall of its fixed seat to increase the anti-slip performance of the bottle body 100. On this basis, the limit screw rod can be rotated so that the limit screw rod is away from the limit groove, and then the rotating ring is rotated, so that the rotating ring drives the rotating disc to rotate. At this time, the rotation of the rotating disc can cause the connecting rods included in the multiple expansion parts to expand when rotating in the arc-shaped opening, so that the connecting rods carrying the arc-shaped plates are extended, and thus the support area at the bottom of the bottle body can be enlarged. Furthermore, the stability of the bottle body can be better improved by using multiple arc-shaped plates carrying rubber pads in cooperation with the anti-slip pad, reducing the damage to the NFC induction chip caused by the bottle body falling due to accidental bumping and tipping.

[0017] S3: NFC chip shielding protection: When the NFC induction chip is not in use, the expansion parts provided on the bottle body are often in a retracted state. The connecting rods of the multiple expansion parts can be retracted and stored along the arc-shaped opening by the reverse rotation of the rotating ring. At this time, the sealing electromagnetic shielding plates provided on the front outer walls of the multiple connecting rods can be tightened together. The multiple sealing electromagnetic shielding plates can better provide sealed shielding protection when the NFC induction chip is not in use, and the multiple sealing electromagnetic shielding plates can also play an electromagnetic shielding role, reducing the adverse effects on the NFC induction chip in a strong electromagnetic interference environment.

[0018] Compared with the prior art, the beneficial effects of the present invention are as follows: This device can integrate the NFC induction chip into the bottom of the water bottle for use, greatly improving its functionality. With the help of the NFC induction chip, the user only needs to gently touch the bottom of the bottle with the mobile phone to obtain accurate water temperature information, understand the real-time data of the water intake, and even receive healthy drinking reminders. At the same time, it jumps to the associated health management mini-program to record long-term drinking habits, providing strong support for a healthy life and endowing the water bottle with new value and experience; Secondly, an anti-slip pad is installed on the outer wall of the device fixing seat to increase the anti-slip performance of the bottle body 100. On this basis, the rotatable limit screw rod can be rotated to make the limit screw rod away from the limit groove, and then the rotating ring is rotated to drive the rotating disk to rotate. At this time, the rotation of the rotating disk can cause the connecting rods included in multiple expansion parts to expand when rotating in the arc-shaped opening, so that the connecting rods carrying the arc-shaped plates extend, thereby expanding the supporting area at the bottom of the bottle body, and then better using the arc-shaped plates carrying rubber pads in cooperation with the anti-slip pad to improve the stability of the bottle body, reducing the damage to the NFC induction chip and the bottle body caused by the higher bottle body falling due to accidental collision; Moreover, when the NFC induction chip is not in use, the expansion parts provided on the bottle body are often in a retracted state. The connecting rods of the multiple expansion parts can be retracted and stored along the arc-shaped opening by rotating the rotating ring in the reverse direction. At this time, the sealing electromagnetic shielding plates provided on the front outer walls of the multiple connecting rods can be tightened together. The multiple sealing electromagnetic shielding plates can better seal and shield when the NFC induction chip is not in use, and the multiple sealing electromagnetic shielding plates can also play an electromagnetic shielding role. The shielding plate can be made of a metal material. Using its electromagnetic shielding characteristics, the NFC induction chip is isolated from the strong magnetic field outside, avoiding the interference and influence of the magnetic field on the chip and reducing the possibility of demagnetization. At the same time, the shielding plate can also play a physical protection role to a certain extent, preventing sharp objects from directly contacting the chip, further protecting the safety of the chip, and ensuring the stability of the NFC function during daily carrying and use. In summary, the protection structure can better protect the NFC induction chip while improving the stability of the bottle body. BRIEF DESCRIPTION OF THE DRAWINGS

[0030] It should be noted that a guiding groove 410 is provided on the rear outer wall of the fixed seat 400, and the multiple guiding grooves 410 are matched with the connecting rods 320.

[0034] A protection method for an NFC bottle bottom induction chip, and its usage steps are as follows: S1: Installation of the NFC induction chip 331: Install the NFC induction chip 331 in the rubber buffer sleeve 334 inside the installation cylinder 330. The rubber buffer sleeve 334 plays a preliminary buffer protection role to reduce the impact of vibrations, etc. on the chip. Threadedly connect the cover plate 332 at the end of the installation cylinder 330, and hermetically connect the glass plate 333 to the inner wall of the cover plate 332 using sealant. At the same time, set a rubber sealing ring on the outer wall of the cover plate 332 to achieve sealed protection of the NFC induction chip 331 inside the installation cylinder 330 without affecting its use, preventing moisture, dust, etc. from entering. And when the NFC induction chip 331 needs to be replaced, the cover plate 332 can be directly disassembled by threading, facilitating the replacement and repair of the NFC induction chip 331.

[0035] S2: Placement for stable support: During use, one end of the outer circumferential wall of the installation cylinder 330 is fixedly connected to the inner wall of the center of the through sliding groove 420, and the other end of the installation cylinder 330 is fixedly connected to the bottom of the bottle body 100 to provide support for subsequent structures. An anti-slip pad 430 is installed on the outer wall of the fixed seat 400 to increase the anti-slip performance of the bottle body 100. On this basis, the rotatable limit screw rod 220 can be rotated to make the limit screw rod 220 away from the limit groove 140, and then the rotating ring 200 is rotated, so that the rotating ring 200 drives the rotating disk 300 to rotate. At this time, the rotation of the rotating disk 300 can cause the connecting rods 320 included in multiple expansion members to expand when rotating in the arc-shaped opening 310, so that the connecting rods 320 carrying the arc-shaped plates 321 extend, and thus the support area at the bottom of the bottle body 100 can be enlarged. Furthermore, the arc-shaped plates 321 carrying rubber pads 322 are better used in cooperation with the anti-slip pad 430 to improve the stability of the bottle body 100, reducing damage to the NFC induction chip 331 caused by the bottle body 100 falling due to accidental bumps and tipping.

[0036] S3: Shielding protection for the NFC chip: When the NFC induction chip 331 is not in use, the expansion members provided on the bottle body 100 are often in a retracted state. The connecting rods 320 of the multiple expansion members can be retracted and stored along the arc-shaped opening 310 by the reverse rotation of the rotating ring 200. At this time, the sealing electromagnetic shielding plates 324 provided on the front outer walls of the multiple connecting rods 320 can be tightened together. The multiple sealing electromagnetic shielding plates 324 can better provide sealed shielding protection when the NFC induction chip 331 is not in use, and the multiple sealing electromagnetic shielding plates 324 can also play an electromagnetic shielding role, reducing the adverse effects on the NFC induction chip 331 in a strong electromagnetic interference environment.

[0037] Working principle of the present invention: The NFC induction chip 331 is installed in the rubber buffer sleeve 334 inside the installation cylinder 330. The rubber buffer sleeve 334 is used to provide preliminary buffer protection, reducing the impact of vibrations, etc. on the chip. At the end of the installation cylinder 330, a cover plate 332 is threadedly sleeved, and a glass plate 333 is hermetically connected to the inner wall of the cover plate 332 using sealant. At the same time, a rubber sealing ring is provided on the outer wall of the cover plate 332 to achieve sealed protection of the NFC induction chip 331 inside the installation cylinder 330 without affecting its use, preventing moisture, dust, etc. from entering. And when the NFC induction chip 331 needs to be replaced, the cover plate 332 can be directly disassembled by threading, facilitating the replacement and repair of the NFC induction chip 331. During use, one end of the circumferential outer wall of the installation cylinder 330 is fixedly connected to the inner wall of the center of the through sliding groove 420, and the other end of the installation cylinder 330 is fixedly connected to the bottom of the bottle body 100, providing support for the subsequent structure. An anti-slip pad 430 is installed on the outer wall of the fixed seat 400 to increase the anti-slip performance of the bottle body 100. On this basis, the rotatable limit screw rod 220 can be rotated to make the limit screw rod 220 away from the limit groove 140, and then the rotating ring 200 is rotated, causing the rotating ring 200 to drive the rotating disk 300 to rotate. At this time, the rotation of the rotating disk 300 can prompt the expansion of the connecting rods 320 included in the multiple expansion members when rotating in the arc-shaped opening 310, causing the connecting rods 320 carrying the arc-shaped plates 321 to extend, thereby expanding the support area at the bottom of the bottle body 100. Furthermore, the arc-shaped plates 321 carrying the rubber pads 322 are better used in cooperation with the anti-slip pad 430 to improve the stability of the bottle body 100, reducing the damage to the NFC induction chip 331 caused by the bottle body 100 falling due to accidental collision and tipping. When the NFC induction chip 331 is not in use, the expansion members provided on the bottle body 100 are often in a retracted state. The connecting rods 320 of the multiple expansion members can be retracted and stored along the arc-shaped opening 310 by the reverse rotation of the rotating ring 200. At this time, the sealing electromagnetic shielding plates 324 provided on the front outer walls of the multiple connecting rods 320 can be tightened together. The multiple sealing electromagnetic shielding plates 324 can better provide sealed shielding protection when the NFC induction chip 331 is not in use, and the multiple sealing electromagnetic shielding plates 324 can also play an electromagnetic shielding role, reducing the adverse effects on the NFC induction chip 331 in a strong electromagnetic interference environment.

It cannot be determined that the specific implementation of the present invention is only limited to these descriptions.

Rotate, at this time, the rotation of the rotating disk (300) can cause the connecting rods (320) included in the multiple extension pieces to expand when the arc-shaped opening (310) rotates, so that the multiple connecting rods (320) carrying the arc-shaped plates (321) are extended, thereby expanding the support area at the bottom of the bottle body (100), thereby better utilizing the multiple arc-shaped plates (321) carrying rubber pads (322) in conjunction with the anti-skid pad (430) to improve the stability of the bottle body (100), and reduce the possibility of the bottle body (100) tipping over due to accidental collisions, thereby reducing the damage to the NFC sensing chip (331) caused by the bottle body (100) falling down; S3: NFC chip shielding protection: When the NFC sensing chip (331) is not in use, the extension piece provided on the bottle body (100) is often in a storage state. The multiple extension pieces can be retracted and stored along the arc-shaped opening (310) by the action of the reverse rotation of the rotating ring (200). At this time, the sealed electromagnetic shielding plates (324) provided on the outer wall in front of the multiple connecting rods (320) can be tightened together. The multiple sealed electromagnetic shielding plates (324) can better perform sealed shielding protection when the NFC sensing chip (331) is not in use, and the multiple sealed electromagnetic shielding plates (324) can also play the role of electromagnetic shielding, thereby reducing the adverse effects on the NFC sensing chip (331) in a strong electromagnetic interference environment.
