[0024] Unless otherwise defined, all technical and scientific terms used in this invention have the same meaning as commonly understood by one of ordinary skill in the art to which this invention pertains; the terminology used in the specification is for the purpose of describing particular embodiments only and is not intended to limit the invention; the terms "comprising" and "having," and any variations thereof, in the specification, claims, and accompanying drawings of this invention are intended to cover non-exclusive inclusion. The terms "first," "second," etc., in the specification, claims, or accompanying drawings of this invention are used to distinguish different objects, not to describe a particular order.

[0025] In this invention, the reference to "embodiment" means that a specific feature, structure, or characteristic described in connection with an embodiment may be included in at least one embodiment of this invention. The appearance of this phrase in various places in the specification does not necessarily refer to the same embodiment, nor is it a mutually exclusive, independent, or alternative embodiment to other embodiments. It will be explicitly and implicitly understood by those skilled in the art that the embodiments described in this invention can be combined with other embodiments.

[0026] To enable those skilled in the art to better understand the present invention, the technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings.

[0027] like Figure 1-5 As shown, an airtightness testing fixture for electronic e-liquid bottles includes a base 1, which serves as the support structure for the entire device and houses a controller (which can be a PLC or an industrial microprocessor). The upper surface of the base 1 is provided with a fixture limiting groove 2 for placing a product fixture 3 containing an electronic e-liquid bottle. The length of the fixture limiting groove 2 is approximately equal to the length of the product fixture 3, facilitating precise placement and positioning of the product fixture 3. The width of the fixture limiting groove 2 is greater than the width of the product fixture 3, thus facilitating the placement of the product fixture 3 into the fixture limiting groove 2.

[0028] A pressure blowing assembly is installed on the base 1, located above the fixture limiting groove 2. The pressure blowing assembly includes a pressure mounting base 4, which is fixedly connected to the upper surface of the base 1 by screws. Five pressure driving mechanisms are installed on the pressure mounting base 4. Each pressure driving mechanism has an air nozzle 5 at its output end. The pressure driving mechanism can drive the air nozzle 5 to abut against the bottle opening of the e-liquid bottle on the fixture limiting groove 2. The air nozzle 5 is used to blow air into the e-liquid bottle on the product fixture 3 from an external air source. A pressure sensor 6 is installed on the lower end face of the air nozzle 5. The pressure sensor 6 is connected to the controller via a cable. The pressure driving mechanism can drive the pressure sensor 6 to extend into the e-liquid bottle on the product fixture 3 to detect the air pressure inside the e-liquid bottle on the product fixture 3.

[0029] During testing, the operator first places the e-liquid bottle onto the product fixture 3, then places the product fixture 3 containing the e-liquid bottle into the fixture limiting groove 2 to secure it. Next, the operator controls the various downward-pressing drive mechanisms to lower the nozzles 5 and pressure sensors 6 until each nozzle 5 seals the corresponding e-liquid bottle opening. Then, an external air source injects high-pressure gas into each e-liquid bottle through the nozzles 5. After a settling time (usually 10 seconds), the pressure sensor 6 detects the pressure value inside the e-liquid bottle. If the pressure value is below the threshold, the e-liquid bottle's airtightness is unqualified; otherwise, it is qualified. After testing, the operator controls the various downward-pressing drive mechanisms to raise the nozzles 5 and pressure sensors 6 to their initial positions. The operator can then remove the product fixture 3 from the fixture placement groove and remove the e-liquid bottle from the product fixture 3.

[0030] For ease of control and operation, a display screen 7 and control buttons 8 are provided on the base 1; the display screen 7 and control buttons 8 are electrically connected to the controller. The display screen 7 can be used to display various working parameters for the operator to view; the control buttons 8 include start, stop, and other operation buttons to facilitate the operator's use of the testing fixture.

[0031] Specifically, the downward pressure drive mechanism includes a downward pressure cylinder 9, which is connected to a controller. The downward pressure cylinder 9 is fixedly mounted on the downward pressure mounting base 4. A downward pressure slider 10 is mounted on the output end of the downward pressure cylinder 9, and the air nozzle 5 is connected to the downward pressure slider 10. During operation, by controlling the downward pressure cylinder 9, the downward pressure slider 10 can be driven to move up and down, thereby driving the air nozzle 5 and the air pressure sensor 6 to move synchronously, achieving the purpose of driving the air nozzle 5 to move up and down.

[0032] In this embodiment, there are five pressing cylinders 9. In other embodiments, the number of pressing cylinders 9 can be any other number.

[0033] To ensure smooth movement, pressure guide rails 11 are installed on the pressure mounting base 4 at corresponding positions to each pressure cylinder 9, and pressure sliders 10 are slidably engaged with their respective pressure guide rails 11. When the pressure cylinder 9 is working, the pressure slider 10 slides on its corresponding pressure guide rail 11; the cooperation between the pressure slider 10 and the pressure guide rail 11 limits and guides the movement direction of the nozzle 5, improving the stability of the detection.

[0034] A pressure head mounting block 13 is connected to the pressure slider 10 via two connecting pins 12. The connecting pins 12 and the pressure slider 10 are in a slidable clearance fit. One end of the connecting pin 12 is fixedly connected to the pressure head mounting block 13, and the other end passes through the pressure slider 10 and can slide on the pressure slider 10. The nozzle 5 is fixedly mounted on the pressure head mounting block 13. Elastic elements 14 are respectively fitted on the connecting pins 12, and the two ends of the elastic elements 14 are respectively pressed against the pressure head mounting block 13 and the pressure slider 10. This buffer structure ensures that the nozzle 5 provides flexible pressure when it comes into contact with the e-liquid bottle, avoiding damage to the product.

[0035] In this embodiment, the elastic element 14 is a helical metal spring. In other embodiments, the elastic element 14 may also be other elastic devices such as a spring sheet.

[0036] The product fixture 3 is provided with multiple product placement slots 31. The shape and size of the product placement slots 31 are adapted to the e-liquid bottles to be tested. The product placement slots 31 are used to place e-liquid bottles, and the positions of the product placement slots 31 correspond one-to-one with the positions of the pressure cylinders 9. In this embodiment, there are five product placement slots 31. In other embodiments, the number of product placement slots 31 can be any other number.

[0037] To facilitate fixing the product fixture 3 within the fixture limiting groove 2, two limiting abutment blocks 15 are placed on the fixture limiting groove 2. During processing, the product fixture 3 is placed into the fixture limiting groove 2, and then the two limiting abutment blocks 15 are placed into the fixture limiting groove 2 respectively, such that one limiting abutment block 15 abuts against one end of the product fixture 3, and the other limiting abutment block 15 abuts against the other end of the product fixture 3. The ends of both limiting abutment blocks 15 away from the product fixture 3 abut against the side wall of the fixture limiting groove 2. Thus, the product fixture 3 is limited and fixed within the fixture limiting groove 2 by the two limiting abutment blocks 15, avoiding the problem of the product fixture 3 shifting during testing.

[0038] In the specific embodiments, the number of limiting abutment blocks 15 can also be any other number, and this utility model does not limit this.

[0039] To limit the e-liquid bottle within the product fixture 3, multiple product limiting blocks 16 are installed on the base 1 at positions corresponding to the fixture limiting groove 2. The product limiting blocks 16 correspond to the product placement grooves 31 on the product fixture 3, with two product limiting blocks 16 for each product placement groove 31. When placing the product fixture 3, it is tilted and placed between the product limiting blocks 16 and the fixture limiting groove 2, so that the e-liquid bottle on the product fixture 3 extends below the product limiting blocks 16. Then, the product fixture 3 is straightened. At this point, the product limiting blocks 16 connect with the upper end of the e-liquid bottle in the corresponding product placement groove 31. The two product limiting blocks 16 press and limit the e-liquid bottle within the product placement groove 31, preventing displacement of the e-liquid bottle during testing and improving the accuracy and stability of the testing operation.

[0040] Working principle:

[0041] 1. Loading and positioning: The operator places the product fixture 3 containing the e-liquid bottle into the fixture limiting groove 2, so that each product limiting block 16 is in contact with the upper end face of the corresponding e-liquid bottle. Then, the two limiting abutment blocks 15 are placed at both ends of the product fixture 3, so that they are respectively abutted and fixed to the product fixture 3 and the fixture limiting groove 2.

[0042] 2. Pressing Down and Sealing: Pressing the start button instructs all pressing cylinders 9 to operate simultaneously, pushing the pressing slider 10 downwards along the pressing guide rail 11. This, in turn, drives the nozzle 5 downwards via the elastic element 14 and the pressure head mounting block 13, until the end of the nozzle 5 presses firmly against the opening of the e-liquid bottle. The movement of the nozzle 5 also causes the pressure sensor 6 to move synchronously, allowing the pressure sensor 6 to extend into the opening of the corresponding e-liquid bottle.

[0043] 3. Inflation and Testing: After the nozzle 5 is sealed, the controller opens the solenoid valve, and compressed air supplied by an external air source fills the e-liquid bottle with gas at a certain pressure (the pressure value can be preset) through the nozzle 5. After inflation is complete, let it stand for 10 seconds.

[0044] 4. Air Pressure Monitoring and Judgment: Air pressure sensor 6 monitors the air pressure changes in each e-liquid bottle in real time and transmits the data to the controller. If the air pressure remains stable or the drop is within the allowable range, the e-liquid bottle is deemed to have passed the airtightness test. If the air pressure drops too quickly and exceeds the threshold, the e-liquid bottle is deemed to have failed the airtightness test.

[0045] 5. Reset and Display: After the test is completed, control the lowering cylinder 9 to lift, causing the air nozzle 5 to leave the bottle opening and reset to the initial position. The test results will be clearly displayed on the display screen 7.

[0046] 6. Unloading: The operator releases the limit stop block 15, takes out the product fixture 3, and sorts the products according to the test results.

The scope of this utility model includes but is not limited to the specific embodiments described above. All equivalent changes made in accordance with this utility model are within the protection scope of this utility model.
