Description

Technical Field

[0001] This utility model relates to the field of leak detection technology, specifically to a kettle leak detection device. Background Technology

[0002] As an everyday water container, the sealing performance of a kettle directly affects the user experience. Rigorous leak-proof testing is conducted before it leaves the factory to ensure product quality and safe use.

[0003] Currently, some manufacturers still use the traditional manual water-filling test to check the seal of kettles. This involves operators filling the kettle with water, tightening the lid, and then visually inspecting or wiping the kettle to determine if leakage has occurred. However, this method has significant drawbacks in practical application: First, water stains easily remain inside the kettle after testing. To completely remove the moisture, a separate drying process must be added, which not only prolongs the production process and occupies space but also increases energy consumption and production costs. Second, residual moisture can easily breed microorganisms in a closed environment, posing a risk of secondary contamination and a hygiene hazard to food contact products.

[0004] Furthermore, if automated pressure equipment is used for testing, the sealing ring, as a key sealing element, will wear, deform, or become contaminated due to continuous friction and material aging after long-term high-frequency use, leading to a decline in its sealing performance. Sealing ring failure not only directly causes pressure leakage during the testing process, resulting in false alarms and misclassifying qualified kettles as leaking products, but also, because it is a consumable part that needs to be replaced periodically, often requires machine shutdown for replacement, severely restricting the continuous operating efficiency of the production line.

[0005] Furthermore, existing equipment generally lacks an effective mechanism to distinguish between "genuine product leakage" and "false leakage caused by seal failure," making it difficult to quickly locate the source of the fault and further increasing maintenance complexity and production uncertainty.

[0006] In summary, a kettle leak detection device needs to be developed to solve the above problems. Utility Model Content

[0007] To address the shortcomings of existing technologies, the technical solution adopted by this utility model is as follows: a kettle leak-proof detection device, comprising: a kettle body and an arc-shaped support plate. The arc-shaped support plate serves as the main load-bearing and structural frame of the device, used for installing and supporting the detection components, and possesses good structural stability. The material is stainless steel. A leak-proof detection mechanism is fixedly connected to the outer surface of the arc-shaped support plate. This leak-proof detection mechanism further has the following characteristics: The detection component is mounted on the outer surface of the arc-shaped support plate. The detection component includes a support base; the support base is used to fix the first motor and is the base for motion transmission.

[0008] A removable sealing component is mounted on the outer surface of a detection component, and the removable sealing component includes a sealing clamp. A single receiving component is installed at the bottom of an arc-shaped support plate, and the single receiving component includes a limiting ring plate.

[0009] Furthermore, a first motor is installed on the inner surface of the support base. A rotating plate is fixedly connected to the output end of the first motor. The rotating plate is used to connect the motor and transmit torque to the first telescopic rods on both sides to realize the rotation of the detection parts. The material is high-strength steel plate. The first telescopic rods are installed on both sides of the bottom of the rotating plate. The first telescopic rods act as actuators, driving the sealing assembly to press down to seal the spout of the kettle. A fixed box is installed at the bottom end of the first telescopic rod. An alarm is installed on the outer surface of the fixed box. When a kettle leak is detected, it immediately alerts the operator through sound and light, realizing real-time quality feedback. An air pump is installed on the inner wall of the fixed box to generate the compressed air source required for detection. It is the power core of the entire pressure detection system. The air pump's air delivery end is connected to an air pipe to deliver compressed air and connect to various pneumatic components to form a detection air circuit. The rigid pipe is made of polyurethane material, which is durable.

[0010] Furthermore, a pressure regulating valve is installed at the bottom of the air tube to precisely set and stabilize the test pressure inside the kettle, preventing excessive pressure from causing deformation or damage to the kettle body. This is crucial for ensuring test consistency. An inflation solenoid valve is installed on the lower surface of the pressure regulating valve to control the opening and closing of the inflation pipeline. Upon receiving a signal, it inflates compressed air into the kettle. A pressure sensor is installed below the inflation solenoid valve to monitor the pressure changes of the closed air circuit system in real time. This is the core sensor for determining whether the kettle is leaking. This device uses a high-precision, high-resolution absolute pressure sensor. A pressure holding solenoid valve is installed below the pressure sensor. It closes after inflation to isolate the inside of the kettle from the air source, forming a closed test chamber for pressure holding testing. An exhaust solenoid valve is fixed to the bottom of the pressure holding solenoid valve through the air tube. It opens after the test to safely and quickly release the compressed air inside the kettle into the atmosphere, preparing for the next test.

[0011] Furthermore, both sides of the support base are fixedly connected to one end of the arc-shaped support plate, and the first telescopic rod is symmetrically arranged on both sides of the first motor.

[0012] Furthermore, a sealing ring is installed on the lower surface of the sealing clamp. The sealing clamp is used to hold and position the sealing ring, ensuring that it can be accurately and stably pressed onto the spout of the kettle. The material is selected as engineering plastic. The sealing ring is in direct contact with the spout of the kettle and forms a seal. It is a vulnerable part that ensures the accuracy of the test results. This device uses wear-resistant and aging-resistant food-grade silicone rubber. A support ring plate is slidably connected to the lower surface of the sealing ring to support the sealing ring. It cooperates with the magnetic block and spring to form the base of the quick-release structure. A sliding rod is slidably connected to the inner wall of the sealing clamp as an unlocking mechanism. When pulled, it can separate the support ring plate from the sealing ring. A pull ring is fixed to one end of the sliding rod, which provides a force point for the operator to manually perform the quick-release operation.

[0013] Furthermore, a compression spring is installed on the inner wall of the sealing clamp, and a first magnetic block is installed on the inner wall of the sealing clamp, with a second magnetic block magnetically attracted to the first magnetic block.

[0014] Furthermore, the sealing clamp and the inner wall of the sealing ring are both fixed to the outer surface of the air tube, and the air tube extends to the bottom of the sealing ring. The support ring plate is symmetrically arranged on both sides of the bottom end of the air tube. The end of the compression spring away from the pull ring is fixed to the side of the support ring plate near the sliding rod. The second magnetic block is installed on the inner side of the support ring plate.

[0015] Furthermore, a triangular plate is fixed to the outer surface of the limiting ring plate. The limiting ring plate is used to guide and position the outer surface of the water bottle during the sorting process, ensuring that it falls accurately into the designated collection box. The bottom of the triangular plate is fixed to the output end of the second motor. The triangular plate connects the limiting ring plate and the output end of the second motor, converting the rotational motion of the motor into the rotation of the limiting ring plate. A control console is installed on the outer surface of the second motor, serving as the control center of the equipment. PLC, motion controller, etc. are installed inside to coordinate the entire inspection process. A second telescopic rod is installed on the inner wall of the control console, serving as an actuator. It extends and retracts inward to drive the circular plate to slide, facilitating the drop of the water bottle body on the upper surface of the circular plate. The circular plate serves as a support platform to support the inspected water bottle body. The output end of the second telescopic rod is fixed to the circular plate. A single collection box is set below the circular plate to collect the unqualified water bottles judged to be leaking, facilitating subsequent centralized processing.

[0016] Furthermore, the inner wall of the single receiving box is provided with a sliding groove, which is formed on the inner wall of the single receiving box and cooperates with the edge of the circular plate to ensure that the circular plate can slide smoothly and play a guiding and limiting role.

[0017] Furthermore, the second motor is mounted on the inner surface at the center of the control console, and the outer surface of the circular plate is slidably connected to the inner surface of the slide groove.

[0018] Compared with the prior art, the beneficial effects of this utility model are as follows: 1. This utility model constructs a closed pneumatic pressure detection system through the coordinated operation of an air pump, pressure regulating valve, air filling, pressure holding, and exhaust solenoid valve assembly, and a high-precision absolute pressure sensor. It can automatically fill the kettle with a constant pressure of clean gas and determine its sealing performance by monitoring the pressure decay during the pressure holding phase. This design replaces the traditional "manual water filling and visual inspection" water inspection method, solving a series of derivative problems caused by water residue inside the kettle, the need for an additional independent and energy-intensive drying process, and the growth of microorganisms from residual water. It avoids secondary pollution and quality risks caused by water residue, and also avoids the production line extension, increased energy consumption, and reduced production efficiency caused by adding a drying step.

[0019] 2. This utility model features two independent sets of first telescopic rods, fixed boxes, and detachable sealing components symmetrically arranged on both sides of the bottom of the rotating plate, forming a dual-inspection station. The rotating plate is driven to rotate 180 degrees by a first motor, allowing switching between work stations within seconds. Combined with a quick-release structure consisting of a pull ring, sliding rod, compression spring, and first and second magnetic blocks, rapid installation and removal of the sealing ring is possible. This design solves the bottleneck problem of sealing ring failure due to wear and aging after long-term high-frequency use, leading to false alarms and requiring the entire inspection process to be interrupted for sealing ring replacement. Simultaneously, the dual-station design provides a physical basis for "secondary verification." It avoids the entire equipment downtime caused by a single failed or suspected sealing ring, enabling parallel operation of production inspection and maintenance / replacement in both time and space, greatly improving the overall utilization rate of the equipment.

[0020] 3. The control console of this utility model is pre-programmed with intelligent judgment logic: when an alarm is triggered during the first detection, the first motor is automatically switched to a standby station for a second detection. If both alarms are triggered, the kettle body is determined to be leaking; if only the first alarm is triggered, the original station's sealing ring is indicated as faulty. For kettles ultimately deemed unqualified, the second telescopic rod is retracted, causing the circular plate to move along the chute, allowing the kettle to fall into a single collection box. This design solves the problem that existing equipment cannot effectively distinguish between "genuine product leakage" and "false leakage of the detection tool (sealing ring)," preventing waste caused by misjudging qualified products as unqualified products due to tool malfunctions. Simultaneously, it achieves automatic identification and physical isolation of unqualified products. This avoids economic losses due to the incorrect discarding of qualified products caused by misjudgment, as well as quality complaints caused by unqualified products being mixed with qualified products and flowing into the market. Through automatic sorting, the inefficiency and potential errors of manual sorting are avoided. Attached Figure Description

Example

[0024] Please see Figure 1 - Figure 7 This utility model provides a technical solution: a kettle leak detection device, comprising: a kettle body 1 and an arc-shaped support plate 2. The kettle body 1 is a kettle, and the arc-shaped support plate 2 serves as the main load-bearing and structural frame of the device, used to install and support the detection component 31, possessing good structural stability. The material is stainless steel. A leak detection mechanism 3 is fixedly connected to the outer surface of the arc-shaped support plate 2. The leak detection mechanism 3 further has the following functions: The detection component 31 is installed on the outer surface of the arc-shaped support plate 2. The detection component 31 includes a support base 311. The support base 311 is used to fix the first motor 312 and is the base for motion transmission.

[0025] A removable sealing component 32 is mounted on the outer surface of the detection component 31. The removable sealing component 32 includes a sealing clamp 321. The single receiving component 33 is installed at the bottom of the arc-shaped support plate 2, and the single receiving component 33 includes a limiting ring plate 331.

[0026] A first motor 312 is installed on the inner surface of the support base 311. A rotating plate 313 is fixedly connected to the output end of the first motor 312. The rotating plate 313 is used to connect the motor and transmit torque to the first telescopic rods 314 on both sides to realize the rotation of the detection part. The material is high-strength steel plate. The first telescopic rods 314 are installed on both sides of the bottom of the rotating plate 313. The first telescopic rods 314 act as actuators to drive the sealing assembly to press down to seal the kettle spout. A fixed box 315 is installed at the bottom end of the first telescopic rods 314. An alarm 316 is installed on the outer surface of the fixed box 315. When a kettle leak is detected, it will immediately alert the operator through sound and light to realize real-time quality feedback. An air pump 317 is installed on the inner wall of the fixed box 315 to generate the compressed air source required for detection. It is the power core of the entire pressure detection system. The air pump 317 is connected to an air pipe 318 to deliver compressed air and connect to various pneumatic components to form a detection air circuit. The rigid pipe is made of polyurethane material and is durable.

[0027] A pressure regulating valve 319 is installed at the bottom of the air pipe 318 to precisely set and stabilize the test pressure of the water bottle, preventing excessive pressure from deforming or damaging the bottle body 1. This is crucial for ensuring test consistency. An inflation solenoid valve 3191 is installed on the lower surface of the pressure regulating valve 319 to control the opening and closing of the inflation pipeline. After receiving a signal, it fills the water bottle with compressed air. A pressure sensor 3192 is installed below the inflation solenoid valve 3191 to monitor the pressure changes of the closed air circuit system in real time. This is the core sensor for determining whether the water bottle is leaking. This device uses a high-precision, high-resolution absolute pressure sensor. A pressure holding solenoid valve 3193 is installed below the pressure sensor 3192. After inflation, it closes to isolate the inside of the water bottle from the air source, forming a closed test chamber for pressure holding testing. An exhaust solenoid valve 3194 is fixed to the bottom of the pressure holding solenoid valve 3193 through the air pipe 318. After the test, it opens to safely and quickly release the compressed air from the water bottle into the atmosphere, preparing for the next test.

[0028] Both sides of the support base 311 are fixedly connected to one end of the arc-shaped support plate 2, and the first telescopic rod 314 is symmetrically arranged on both sides of the first motor 312.

[0029] A sealing ring 322 is installed on the lower surface of the sealing clamp 321. The sealing clamp 321 is used to clamp and position the sealing ring 322, ensuring that it can be accurately and stably pressed onto the spout of the kettle. The material is selected as engineering plastic. The sealing ring 322 is in direct contact with the spout of the kettle and forms a seal. It is a vulnerable part that ensures the accuracy of the test results. This device uses wear-resistant and aging-resistant food-grade silicone rubber. A support ring plate 323 is slidably connected to the lower surface of the sealing ring 322 to support the sealing ring 322. It cooperates with the magnetic block and spring to form the base of the quick-release structure. A sliding rod 324 is slidably connected to the inner wall of the sealing clamp 321 as an unlocking mechanism. When pulled, it can separate the support ring plate 323 from the sealing ring 322. A pull ring 325 is fixed to one end of the sliding rod 324, which provides a force point for the operator to manually perform the quick-release operation.

[0030] A compression spring 326 is installed on the inner wall of the sealing clamp 321, and a first magnetic block 327 is installed on the inner wall of the sealing clamp 321. The first magnetic block 327 magnetically attracts a second magnetic block 328.

[0031] The sealing clamp 321 and the sealing ring 322 are both fixed to the outer surface of the air pipe 318 at their central inner walls, and the air pipe 318 extends to the bottom of the sealing ring 322. The support ring plate 323 is symmetrically arranged on both sides of the bottom end of the air pipe 318. The end of the compression spring 326 away from the pull ring 325 is fixed to the side of the support ring plate 323 near the sliding rod 324. The second magnetic block 328 is installed on the inner side of the support ring plate 323.

[0032] A triangular plate 332 is fixedly attached to the outer surface of the limiting ring plate 331. The limiting ring plate 331 is used to guide and position the water bottle during the sorting process, ensuring that it falls accurately into the designated collection box. The bottom of the triangular plate 332 is fixedly attached to the output end of the second motor 333. The triangular plate 332 connects the limiting ring plate 331 and the output end of the second motor 333, converting the rotational motion of the motor into the rotation of the limiting ring plate 331. A control console 334 is mounted on the outer surface of the second motor 333, serving as the control center of the equipment. Equipped with a PLC, motion controller, etc., to coordinate the entire testing process, the inner wall of the control console 334 is fitted with a second telescopic rod 335, which acts as an actuator. The rod extends inward to slide the circular plate 336, facilitating the drop of the kettles from the upper surface of the circular plate 336. The circular plate 336 serves as a support platform to receive the kettles being tested. The output end of the second telescopic rod 335 is fixedly connected to the circular plate 336. A single collection box 337 is installed below the circular plate 336 to collect the non-conforming kettles that are determined to be leaking, facilitating subsequent centralized processing.

[0033] The inner wall of the single collection box 337 is provided with a sliding groove 338, which is formed on the inner wall of the single collection box 337 and cooperates with the edge of the circular plate 336 to ensure that the circular plate 336 can slide smoothly and play a guiding and limiting role.

[0034] The second motor 333 is mounted on the inner surface of the center of the control console 334, and the outer surface of the circular plate 336 is slidably connected to the inner surface of the slide groove 338.

[0035] The working principle is as follows: First, the equipment enters the initial preparation state. The operator places the kettle body 1 to be tested on the upper surface of the circular plate 336 inside the limiting ring plate 331. At this time, the circular plate 336 is positioned below the limiting ring plate 331 under the action of the second telescopic rod 335, and its outer edge forms a sliding fit with the sliding groove 338 on the inner wall of the single collection box 337. The operator presses the start test button on the surface of the control console 334, and the PLC control system inside the control console 334 starts the test program. Subsequently, the first motor 312 starts and drives the rotating plate 313 to rotate through the output end, so that the first telescopic rod 314 and the sealing assembly installed on both sides of the bottom of the rotating plate 313 move to directly above the kettle.

[0036] Then, the equipment performs a sealing and pressure detection process. The first telescopic rod 314 extends downward, pushing the fixed box 315 and the entire air circuit system downward, so that the sealing ring 322 on the lower surface of the sealing clamp 321 fully contacts the spout of the kettle and forms a sealed space. The air pump 317 starts to generate compressed air, which flows sequentially through the air pipe 318, the pressure regulating valve 319, the inflation solenoid valve 3191, and the pressure holding solenoid valve 3193, and is monitored in real time by the pressure sensor 3192, finally entering the kettle body 1. The pressure regulating valve 319 ensures that the inflation pressure is stable at the set value to prevent the kettle body 1 from deforming due to excessive pressure. When the pressure sensor 3192 detects that the system pressure has reached the predetermined value, the inflation solenoid valve 3191 and the pressure holding solenoid valve 3193 close sequentially, forming a closed detection chamber inside the kettle body 1. During the pressure holding stage, the pressure sensor 3192 continuously monitors the pressure change. If the detected pressure drop exceeds the set threshold, the alarm 316 immediately issues an audible and visual alarm.

[0037] Next, the equipment performs test result judgment and sorting. The control console 334 judges the sealing performance of the kettle based on the data from the pressure sensor 3192. If the test is qualified, the alarm 316 emits a normal sound; if the test is unqualified, the control console 334 records the fault information and starts a secondary verification procedure: the first motor 312 starts again and drives the rotating plate 313 to rotate 180 degrees through the output end, so that the sealing component on the other side moves to directly above the kettle, and the first telescopic rod 314 presses down again, using a new sealing ring 322 to repeat the above test process. If both tests trigger an alarm, it is determined that the kettle body is leaking; if only one alarm is triggered, it indicates that the sealing ring 322 may have failed. For kettles that are confirmed to be unqualified, the second telescopic rod 335 retracts, causing the circular plate 336 to slide inward along the slide groove 338, so that a gap is formed at the position where the circular plate 336 is located, thereby causing the unqualified kettle to lose the support of the circular plate 336 and fall into the single collection box 337 for subsequent centralized processing.

[0038] Finally, the equipment performs a quick replacement procedure for the sealing ring 322. It's important to note that over time, the testing equipment relies on a rubber sealing ring 322 in close contact with the kettle spout to form a seal. On automated production lines, thousands or even tens of thousands of kettles may be tested daily. This sealing ring 322 continuously rubs against the spout and accumulates dust and other contaminants from the production line. As the surface of the sealing ring 322 scratches, becomes smooth, or sticky, its sealing performance deteriorates, and the equipment begins to issue false alarms—good kettles are judged to be leaking because the pressure is leaking from the worn sealing ring 322, not the kettle itself. Eventually, the sealing ring 322 completely fails, testing cannot proceed, and the machine must be stopped for replacement. Therefore, quick replacement of the sealing ring 322 is necessary. This equipment can also perform airtightness testing on most kettles on the market, such as some bullet-shaped kettles with similar body widths.

[0039] Therefore, when the system prompts that the sealing ring 322 needs to be replaced, the first motor 312 starts and drives the rotating plate 313 to rotate 180 degrees through the output end, so that the sealing component on the other side moves to the top of the kettle. The first telescopic rod 314 presses down again, and the above detection process is repeated with the new sealing ring 322. The sealing ring 322 that needs to be replaced can be quickly moved to an open position on the other side, which is convenient for the operator to replace quickly without delaying the normal operation of the detection work. When disassembling the sealing ring 322, the operator simultaneously pulls the pull rings 325 outward from both sides of the sealing clamp 321, causing the sliding rod 324 to slide on the inner wall of the sealing clamp 321. This causes the second magnetic block 328 installed on the support ring plate 323 to finally attract the first magnetic block 327 on the inner wall of the sealing clamp 321. At this time, the compression spring 326 is in a compressed state, and the sealing ring 322 immediately falls off the sealing clamp 321, which can realize the quick disassembly of the sealing ring 322. When replacing the new sealing ring 322, simply place the new sealing ring 322 on the support ring plate 323 and push the pull rings 325 on both sides inward to separate the magnetic blocks. The automatic positioning and installation can be completed under the elastic reset action of the compression spring 326.

[0040] In summary, this invention extends the traditional equipment's single function of determining "product qualification" by creating an intelligent device capable of self-diagnosing tool status. It innovatively combines dual-station switching with secondary verification logic on the control console. By comparing the detection results from two independent stations, it can automatically and accurately diagnose whether the fault originates from a leak in the kettle body or a failed seal. This diagnostic capability is lacking in existing, simply assembled equipment, providing intelligent decision-making support for subsequent precise maintenance and sorting operations.

[0041] Meanwhile, the removable sealed component 32 (a combination of pull ring 325, sliding rod 324, and magnet and spring) of this device is not an independent, general-purpose design, but a dedicated solution serving the core objective of "non-stop testing." It is precisely this tool-free design, allowing for disassembly and assembly by hand within seconds, that maximizes the value of "dual-station switching." It ensures that while the equipment can continuously test at one station, rapid manual maintenance can be conveniently performed at the other, thus transforming traditional "downtime for maintenance" into "parallel working time" and improving the overall utilization rate of the equipment.

[0042] Secondly, the various components work synergistically in this solution. Pneumatic detection provides a pollution-free and quantifiable testing basis; dual-station operation provides the physical basis for fault diagnosis and uninterrupted operation; quick-change mechanism ensures the efficiency of realizing the value of dual-station operation; and intelligent sorting automates the execution of diagnostic results. Together, they form a complete closed loop from "detection-diagnosis-decision-execution-maintenance," systematically solving the pollution problems of traditional water testing methods, as well as the interconnected and comprehensive technical problems of existing automated equipment, such as high false alarm rates, long maintenance downtime, and inability to locate fault sources.
