Description

Technical Field

[0001] This invention relates to the field of sealing technology for wine storage containers, and in particular to a variable diameter wine jar sealing device and its self-locking anti-theft system. Background Technology

[0002] Wine jars (especially earthenware and porcelain jars) have a long history as containers for storing and brewing wine in China and around the world. They are one of the core pieces of equipment in traditional brewing processes (such as yellow wine, baijiu, and wine), and are crucial for the "aging" and "maturation" of the wine. In the final stage of brewing, the wine needs to be bottled into specially made earthenware jars and sealed for storage. Generally, a layer of plastic film is placed over the mouth of the jar for sealing, and then a lid is placed on top of the plastic film and pressed down to achieve a seal. However, this sealing structure is unstable and increases the risk of contamination of the wine.

[0003] Patent document CN222906345U discloses a wine jar lid, including a lid body with an inlet / outlet. A cover plate is elastically hinged to the lid body to cover the inlet / outlet. The lid body also has a lock body with a latch that engages with it. One end of the latch outside the lock body has a bevel that engages with the cover plate. The lock body has a trigger mechanism to drive the latch to retract. This application achieves automated opening and closing of the wine jar lid, thereby improving the sealing effect. However, ceramic jars or bottles often have large differences in mouth size due to handcrafting. This wine jar lid cannot be adapted to wine jars or bottles with different mouth sizes, requiring customized production, making it non-reusable, costly, and incompatible. Summary of the Invention

[0004] In order to overcome the shortcomings of the prior art, the purpose of this invention is to enable the reuse of wine jars with different mouth sizes, reduce the cost of use, and improve compatibility.

[0005] To achieve the above objectives, the present invention provides a variable-diameter wine jar sealing device, comprising: The lid is used to cover the mouth of the wine jar to be sealed. A hanging bracket is provided on the side of the lid facing the mouth of the wine jar to be sealed; The transmission assembly has one end slidably connected to the suspension bracket, and the other end is provided with at least two clamping members around the outer edge of the jar mouth; A drive assembly, which is disposed on the suspension bracket and is used to drive the transmission assembly to make smooth movements, so that the clamping member can move away from the outer edge of the jar mouth, and can return to the original position and engage with the outer edge of the jar mouth.

One end of the return spring is connected to the second slider, and the other end is connected to the clamping member. The output end of the pressure sensor is connected to the second slider. The pressure sensor is electrically connected to the main controller and is used to monitor the pressure of the second slider on the wine jar to be sealed and output a pressure value. The main controller is electrically connected to the rotary motor and is used to receive the pressure value output by the pressure sensor and determine whether a preset value has been reached. The rotary motor is used to receive the signal that the pressure value has reached the preset value and stop rotating.

[0010] To achieve the above objectives, another aspect of the present invention provides a self-locking anti-theft system for monitoring the sealing of wine jars, comprising a sealing device, a micro switch, and a buzzer.

The main controller receives the first abnormal signal and outputs a first alarm signal. The rotary motor is used to receive the first alarm signal and activate the self-locking mode. The buzzer is electrically connected to the main controller and is used to receive the first alarm signal and activate the buzzer alarm.

[0011] Preferably, the device also includes a metal detection coil and an audible and visual alarm. The metal detection coil is located in the sealing device and electrically connected to the main controller. It is used to monitor whether a magnetic tool is approaching the vicinity of the wine jar to be sealed and output a second abnormal signal indicating that a magnetic tool is approaching. The main controller receives the second abnormal signal and outputs a second alarm signal. The rotary motor is used to receive the second alarm information and activate a self-locking mode.

Detailed Implementation

[0017] The present invention will now be described in more detail with reference to the accompanying drawings. It should be noted that the following description of the present invention with reference to the accompanying drawings is merely illustrative and not restrictive.

[0018] Where possible, the various embodiments described below can be rearranged to form other embodiments not shown in the following description; the various technical features described below can also be rearranged to form other embodiments not shown in the following description.

[0019] Example 1 Please see Figure 1-5 To achieve a sealing effect for wine jars with mouths of different sizes, this embodiment provides a variable diameter wine jar sealing device, including a lid 1, a suspension bracket 2, a transmission component 3, and a drive component 5. The lid 1 is used to cover the mouth of the wine jar to be sealed. The suspension bracket 2 is located on the side of the lid 1 facing the mouth of the wine jar to be sealed. One end of the transmission component 3 is slidably connected to the suspension bracket 2, and the other end is provided with at least two clamping members 4 around the outer edge of the mouth. The drive component 5 is located on the suspension bracket 2 and is used to drive the transmission component 3 to make smooth movements, so that the clamping members 4 can move away from the outer edge of the mouth and can return to their original position and lock onto the outer edge of the mouth.

[0020] In this embodiment, the wine jar to be sealed is selected, but not limited to, a round mouth. Conventional sealing devices use snap-fit ​​or threaded structures, which are easily disassembled by force. To improve tamper resistance, the sealing device of this invention is equipped with four clamping members 4 for round mouths, thereby improving the stability of the clamping. The four clamping members 4 are evenly spaced around the outer edge of the mouth. Each clamping member 4 has a baffle 6 on the side facing the lid 1. Each baffle 6 is arc-shaped, and the positions of adjacent baffles 6 are overlapping, making the whole structure circular, thus surrounding the outer edge of the mouth and protecting the mouth of the wine jar to be sealed.

[0021] The transmission assembly 3 includes a first slider 31, a limiting shaft 33, a limiting plate 34, and a plate body 36. The plate body 36 is circular and is connected to the suspension bracket 2 via a rotating shaft 10 and a bearing. The lid 1 adopts a bent-form structure, forming a cavity with an opening on one side. The side of the lid 1 away from the wine jar to be sealed has a through hole communicating with the cavity. The plate body 36 is located at the through hole of the lid 1 and fits snugly. The rotating shaft 10, lid 1, suspension bracket, plate body 36, and jar mouth are all set on the same central axis. The plate body 36 is fixedly connected to the suspension bracket 2 to form a sealed cavity 11.

[0022] Because four clamping members 4 are provided, four sets of first sliders 31, limiting shafts 33, and limiting plates 34 are also provided, each set corresponding to one clamping member 4 to assist the directional movement trajectory of the clamping member 4. The suspension bracket 2 is equipped with a sliding groove 32 for each first slider 31 and is located on one side of the sealed cavity 11, and is equidistantly arranged around the central axis of the suspension bracket 2. The sliding groove 32 is a straight groove, with one end located at the edge of the suspension bracket 2 and the other end close to the central axis of the suspension bracket 2, thereby dividing the sealed cavity 11 into four. The first slider 31 is slidably disposed in the sliding groove 32, with one end located at the edge of the suspension bracket 2 extending out of the suspension bracket 2 and fixedly connected to the clamping member 4. Each limiting plate 34 is located between the corresponding first slider 31 and the plate surface and is fixedly connected to the suspension bracket 2. The limiting shaft 33 is located on the side of the first slider 31 facing the panel. The limiting plate 34 is provided with a slot-shaped hole for the limiting shaft 33 to pass through. The movement trajectory of the limiting shaft 33 in the slot-shaped hole is the same as the movement trajectory of the first slider 31 in the sliding groove 32.

[0023] The plate 36 has four guide grooves 37 on the side facing the transmission assembly 3. The four guide grooves 37 are arc-shaped and symmetrically arranged around the central axis of the plate 36, forming a radial petal structure. Each guide groove 37 corresponds to each limiting shaft 33 and is used for the insertion of the limiting shaft 33. The drive assembly 5 includes a rotary motor 51, which is located in the sealed cavity 11 of the suspension bracket 2. The output end of the rotary motor 51 is provided with a drive gear 52. The edge of the plate 36 is provided with a circumferential tightening ring (12-petal silicone-nylon composite petals). The inner side of the circumferential tightening ring is provided with an arc-shaped rack guide rail 53 that meshes with the drive gear 52, with a radial extension range of Φ60–85mm (covering 90% of the pottery jar diameter). The rotary motor 51 can be a stepper motor, and the drive gear 52 (module 1.5, number of teeth 24) is paired with a planetary reducer (reduction ratio 10:1) to increase the torque to 5N·m.

[0024] When the sealing device is unlocked, each limiting shaft 33 is located at the end of the corresponding guide groove 37 away from the central axis of the plate 36, and at the end of the slotted hole away from the central axis of the suspension bracket 2. Each limiting shaft 33 drives each first slider 31 to extend out of the suspension bracket 2, so that each clamping member 4 is away from the mouth of the wine jar to be sealed. When the sealing device needs to be locked, the rotary motor 51 drives the drive gear 52 to rotate. The drive gear 52 drives the plate 36 to rotate, which drives each guide groove 37 to move. The end of the guide groove 37 near the central axis of the plate 36 moves towards the corresponding limiting shaft 33, thereby driving each limiting shaft 33 to move simultaneously along the slotted hole towards the central axis of the suspension bracket 2. Each limiting shaft 33 drives each first slider 31 to retract into the suspension bracket 2, so that each clamping member 4 is engaged with the outer edge of the mouth of the wine jar to be sealed, thereby achieving the locked state.

[0025] Example 2 Please see Figure 1-8 Conventional snap-fit ​​or threaded structures are easily disassembled by force, and traditional lids rely solely on screw caps for sealing. To improve mechanization and automate opening and closing, this invention provides a variable-diameter wine jar sealing device based on the first embodiment. A main controller 7 is installed inside the sealing cavity 11 of the suspension bracket 2. Each clamping member 4 is equipped with a second slider 8, a pressure sensor, and a return spring 9. The second slider 8 is slidably connected to the clamping member 4 and passes through the outer edge of the clamping member 4 facing the jar opening. One end of the return spring 9 is connected to the second slider 8, and the other end is connected to the clamping member 4.

[0026] The output end of the pressure sensor is connected to the second slider 8. The pressure sensor is electrically connected to the main controller 7 and is used to monitor the pressure of the wine jar to be sealed on the second slider 8 and output the pressure value. The main controller 7 is electrically connected to the rotary motor 51 and is used to receive the pressure value output by the pressure sensor and determine whether the preset value has been reached. The rotary motor 51 is used to receive the signal that the pressure value has reached the preset value and stop rotating.

[0027] When the sealing device is in the locked state, each clamping member 4 moves towards the outer edge of the jar opening to be sealed. When the top of the second slider 8 abuts against the outer edge of the jar opening, the clamping member 4 continues to move. Due to the pushing force of the jar on the second slider 8, the second slider 8 retracts into the clamping member 4, thereby triggering the pressure sensor. The pressure sensor begins to monitor and transmit the feedback sealing force to the main controller 7. The main controller 7 has a preset sealing force. If the received sealing force data is not less than 30N, it outputs a signal to the rotary motor 51, and the rotary motor 51 stops rotating.

[0028] Example 3 Please see Figure 1-9 Existing wine jar sealing methods are susceptible to theft or tampering of the wine, and cannot be monitored in real time. Relying on physical seals (such as anti-counterfeiting patches), these seals are easily damaged and lack traceability. This invention combines mechanical self-adaptation with electronic monitoring technology to solve the problems of traditional wine jar lids being unable to adapt to different diameters, having weak tamper resistance, and lacking active anti-theft mechanisms. Based on Embodiment 2, this invention provides a self-locking anti-theft system for wine jar sealing monitoring, including a sealing device, micro switch, buzzer, metal detection coil, audible and visual alarm, vibration sensor, and locator. Triple intrusion detection is achieved through a multi-sensor alarm module. Power redundancy design: When the main power supply (lithium battery) is interrupted, a supercapacitor maintains sensor operation for ≥72 hours. The rotary motor 51 can be a worm gear DC geared motor, which utilizes the unidirectional nature of the worm gear's transmission to prevent reverse rotation, achieving a self-locking mode and thus improving tamper resistance.

[0029] A microswitch is located on the sealing device and electrically connected to the main controller 7. It is used to monitor whether the sealing device is being pried open and to output a first abnormal signal indicating that prying has occurred. The trigger condition is that the flap displacement is greater than 2mm. The main controller 7 receives the first abnormal signal and outputs a first alarm signal. The rotary motor 51 is used to receive the first alarm signal and activate the self-locking mode. A buzzer is electrically connected to the main controller 7 and is used to receive the first alarm signal output by the main controller 7 and activate the buzzer alarm.

[0030] A metal detection coil is installed in the sealing device and electrically connected to the main controller 7. It is used to monitor whether a magnetic tool is approaching the vicinity of the wine jar to be sealed and outputs a second abnormal signal indicating that a magnetic tool is approaching. The trigger condition is that the magnetic tool approaches within 5cm. The main controller 7 receives the second abnormal signal and outputs a second alarm signal. The rotary motor 51 is used to receive the second alarm information and activate the self-locking mode. The audible and visual alarm is electrically connected to the main controller 7 and is used to receive the second alarm signal and activate the audible and visual alarm.

[0031] A vibration sensor is installed in the sealing device and electrically connected to the main controller 7. It is used to monitor whether there is a third abnormal signal indicating impact acceleration in the sealed wine jar and outputs a third abnormal signal indicating the presence of impact acceleration. The trigger condition is that the impact acceleration is greater than 5g, such as a hammer blow. The main controller 7 receives the third abnormal signal and outputs a third alarm signal. The positioner is electrically connected to the main controller 7 and is used to receive the third alarm signal and activate the positioning alarm.

[0032] The sealing device is equipped with a mechanical emergency interface, including a mechanical lock hole and a key. The self-locking mode can be manually released by rotating the key 270° in the mechanical lock hole. The mechanical emergency interface meets the requirements for forced opening by fire / security checks, preventing liquid from remaining due to electronic system failure.

[0033] Example 4 To achieve a multi-faceted linkage effect between anti-theft monitoring and security for wine jars, this invention provides a self-locking anti-theft system for wine jar sealing monitoring, based on Embodiment 3. This system also includes a cloud platform, a wireless communication module, and a management terminal. The cloud platform is electrically connected to the sealing device via the wireless module to receive real-time status data output by the sealing device. The management terminal is interactively connected to the cloud platform to receive real-time status data output by the cloud platform and to control the locking or unlocking of the self-locking mode of the rotating motor 51. The wireless communication module can be an NB-IoT module, and the management terminal can be a mobile APP. The NB-IoT module uploads status data to the cloud platform and supports remote authorization for unlocking or forced locking via the mobile APP. This upgrades the system from passive sealing to a closed-loop anti-theft system of real-time monitoring, alarm, and evidence collection, achieving a theft detection rate of ≥95%.

[0034] Although several specific embodiments of the present invention have been shown and described above, it is to be understood that the above embodiments are merely exemplary and should not be construed as limiting the scope of protection of the present invention. Any non-substantial changes and substitutions made by those skilled in the art are within the scope of protection claimed by the present invention.
