30-Position Suction Machine (100/300ml) DR-CX30

The 30-station suction machine is a device used to measure the draw resistance of finished electronic cigarettes. It is generally applied in the quality control of electronic cigarette production and fatigue performance testing. This equipment operates based on the principle of simulating manual suction with a piston. Specifically, when the test instrument's piston simulates manual suction of the electronic cigarette and inhales a fixed flow rate of air (for example, 17.5 ml/s), a certain vacuum pressure will be generated at the inhalation end of the electronic cigarette, which is the draw resistance. The test instrument will measure this pressure in real time, that is, the real-time draw resistance. Through this method, the draw resistance characteristics of the electronic cigarette can be accurately measured. 

Product Features and Characteristics

Users can choose between cycle testing and single testing modes.

Each testing station of the device is equipped with a USB charging port for product charging.

Parameters for judgment can be set to determine whether the resistance to suction of each test is qualified.

Core Technology Highlights and Functional Design

✅ 30-Station Parallel Testing: Efficiency Leap, Suitable for High-Speed Production Lines

✦ High-Density Station Design:

30 independent suction modules work simultaneously (with a 20mm spacing, compact layout), and the test time for each station is ≤15 seconds (including loading/unloading - suction - data collection). A single machine can test ≥7200 e-cigarettes per hour (compared to only 240 per hour for traditional single-station equipment). It supports "full-station start" or "single-station shielding" (by selecting the shielded stations on the touch screen), flexibly meeting the needs of "batch full inspection" or "repair random inspection" (for example, when only 10 e-cigarettes are tested, 20 stations can be shielded).

✦ Modular Suction Units:

Each station is equipped with an independent piston pump + pressure sensor (to avoid interference between stations), ensuring "zero crosstalk" in the suction resistance measurement of each e-cigarette.

The piston stroke is adjustable (100ml/300ml dual mode), adapting to different suction requirements such as small e-cigarettes (100ml short suction) and large e-cigarettes (300ml deep suction) (traditional equipment only supports a single capacity). 

✅ Piston-Driven Precise Suction: Constant Flow, More Reliable Resistance Measurement

✦ Constant Flow Suction Control Technology:

Equipped with a high-precision servo piston pump (flow accuracy ±0.5 ml/s), it can set a fixed flow rate (e.g., 17.5 ml/s, in line with ISO 20768 e-cigarette testing standards);

The suction speed is adjustable (0.5–2 times/second), simulating real usage scenarios such as "light draw (1 time/second)" and "rapid draw (2 times/second)", ensuring that the resistance data is strongly correlated with the user's actual experience (traditional devices have a flow fluctuation > 2 ml/s).

✦ Real-Time Resistance Measurement System:

A highly sensitive pressure sensor (range -10 kPa to 0 kPa, accuracy ±0.01 kPa) continuously collects the vacuum pressure at the e-cigarette's inhalation end;

Simultaneously outputs a "time-pressure" dynamic curve (sampling frequency 100 Hz), fully recording the entire process from "suction start - pressure rise - stabilization - end", accurately capturing abnormal resistance (such as sudden pressure changes, excessive fluctuations). 

✅ Multi-mode testing support: Covering both draw resistance and fatigue scenarios

✦ Basic draw resistance detection:

A single puff can complete the draw resistance measurement (target pressure range: -4kPa to -8kPa, customizable), with "green label" marking for OK products (pressure within range) and "red label" for NG products (if pressure is too high/low, corresponding to too tight/too loose draw resistance);

Supports "batch statistics" function (e.g., 28 out of 30 OK, yield rate 93.3%), for quick batch quality assessment.

✦ Cycle fatigue testing:

Can set "puffing - standby" cycle (e.g., 1 puff per second, for 100,000 cycles), simulating the "3-year lifespan" of an e-cigarette (based on an average of 200 puffs per day);

Real-time recording of "draw resistance drift" during the cycle (normal ≤ 0.2kPa per 10,000 cycles), to assess draw resistance stability (traditional equipment can only test up to 20,000 cycles);

Automatically generates a "draw resistance attenuation curve" after fatigue testing, assisting in predicting aging issues such as "loosening of draw resistance" (e.g., pressure drop due to aging of silicone seals). 

✅ Intelligent Data Management: Traceable and Compliant

✦ Full-process Data Recording:

Store 500,000 sets of test records (time/sample number/drawing mode/pressure curve/average draw resistance), supporting quick search by "batch/date/model";

Automatically mark abnormal data (e.g., "Pressure at the 5th station exceeds the upper limit"), traceable to specific test time and operator, facilitating responsibility determination.

✦ Multi-format Report Output:

Export Excel/CSV reports via USB (including original curves and compliance determination results);

Optional LIMS system interface to achieve real-time linkage of test data with the production line MES system (suitable for smart factories), supporting "automatic rejection of defective products" (e.g., NG product information synchronized to sorting robots). 

Application scenarios and customer value

✅ Full inspection on production lines: Improved yield and reduced costs

✦ Adaptability to production lines:

Seamlessly integrated with the "filling - capping - testing" stage of e-cigarette assembly lines, with each unit inspection taking less than 15 seconds, meeting the high-speed production line requirement of "120 units per minute";

The pass rate of suction resistance has increased from 85% (manual spot checks) to 99%, reducing customer complaints caused by "excessively tight or loose suction resistance" (traditional manual inspection based on feel has an error rate of over 15%). 

✅ R&D Parameter Calibration: Accelerate Product Iteration

✦ Multi-scheme Comparative Testing:

Simultaneously test 30 different designs of electronic cigarettes (such as different airway diameters, seal material);

Output the correlation curves of "airway diameter - suction resistance" and "material - fatigue attenuation", assisting the R&D team in quickly locking the optimal design (traditionally, it would require 3 separate tests, reducing the time by 70%). 

✅ Third-party Testing: The "Golden Certificate" of Authority

✦ Compliance Support:

Compliant with global mainstream standards such as ISO 20768 (International Standard for E-cigarette Testing) and GB 41708 (Chinese National Standard for E-cigarettes);

Test reports include original pressure curves and environmental parameter records, which can be directly used for product export certifications (such as EU TPD and US PMTA). 

Reliability and Maintenance

✅ Structural Durability:

✦ The piston pump has a lifespan of ≥5 million strokes (equivalent to continuous testing of 200,000 e-cigarettes);

✦ The pressure sensor has undergone 100,000 cycle tests (with no drift or attenuation). 

✅ Easy-to-maintain design:

✦ The suction module supports "snap-on disassembly" (no tools required, replacement completed within 5 minutes);

✦ Annual calibration takes only 1 hour (original factory standard flow generator + pressure calibration parts provided);

✦ Self-diagnostic function for faults (displaying error codes such as "flow deviation" and "sensor failure"), guiding quick repair. 

✅ Operation Process (5 Steps to Learn and Use Immediately)

✦ Parameter Setting → Select the test mode on the touch screen (basic draw resistance/fatigue test), and set the draw volume (100ml/300ml), flow rate (17.5ml/s), and cycle count (e.g., 100,000 times);

✦ Loading and Clamping → The operator takes 30 e-cigarettes and inserts them one by one into the fixture at the work station (secured by elastic silicone pads to prevent deformation from squeezing);

✦ Start Testing → Click the "Start" button, and the device automatically performs the draw action, displaying the pressure curves of each work station in real time (green: normal; red: abnormal);

✦ Result Output → After the test is completed, the qualified products flow into the packaging line, and the non-qualified products (such as those with excessive draw resistance) are removed for repair; the fatigue test generates a "draw resistance attenuation report" to guide material optimization (such as replacing more aging-resistant seals).
