With the improvement of living standards, electric shavers are more and more favored by male consumers for their quick and convenient advantages. However, due to the special nature of the use of the scene, electric shavers need to have a good waterproof sealing performance, in order to ensure the safety of use.
Electric shavers in use(after-shave wash)Frequent contact with water, so the product design must be completely sealed to prevent water seepage into the internal short circuit. Also need to withstand a certain amount of vibration impact, shell airtightness is directly related to the safety of the circuit.
This requires a comprehensive and precise test of the airtightness of electric shavers. Therefore, airtightness testing of electric shavers is a key step in ensuring product quality.
Ⅰ.Test Principle
In order to evaluate the airtightness of electric shavers, a common test method is the negative pressure vacuum test, which requires a negative pressure type airtightness tester.(also known as a seal tester)The
This method places the razor into a vacuum chamber, generating a pressure difference between the inside and outside of the product, and determining the sealing level of the product by observing the pressure change in the chamber. A rapid rise in pressure indicates that the product is poorly airtight; a stable pressure indicates a good airtightness.
Compared to the traditional water immersion leak detection method, theNegative pressure vacuum technology is easy to operate, good repeatability, accurate and reliable test results.
Ⅱ.Application Cases
Single channel negative pressure air tightness tester:
Comparison of sealing test data between good and defective products, high precision airtightness and waterproof testing equipment
Four-channel turntable airtightness tester:
4 razors can be tested at a time, saving labor, and the production line comes standard with a waterproof leak detector.
In both airtightness tests, the overall sealing performance of the razor is verified using a negative pressure vacuum test.By testing the airtightness of the shaver, it ensures that its internal components are not contaminated by external dust, moisture or other impurities, thus improving its life and performance.
The client said:
Nowadays, before purchasing an electric shaver, many consumers will know whether the product can be washed in water and whether its waterproof rating can reach IPX7. After adopting JCGK's airtightness testing program, the yield rate of our products has been greatly improved and upgraded, and the multi-channel airtightness tester has made the production more efficient, which has increased the core competitiveness of our electric shavers and gained the trust of the consumers.
Currently, JCGK's negative pressure air tightness tester has been widely used in major electric razor manufacturers, significantly reducing the product defect rate and improving production efficiency.
III.Inspection steps
When using an electric shaver airtightness tester for waterproof testing, you generally need to follow the steps below:
- Prepare the product under test:Place the product to be tested into the tooling fixture.
- Connect the air source and air line:Connect the airtightness tester to the factory air source (or booster pump) and make sure that the fixtures and instruments are free of air.
- Set the test parameters:According to the waterproof requirement of the product under test, set the corresponding airtightness test parameters, such as pressure range, test time, leakage rate, etc.
- Start testing:Press the test button, the instrument will automatically carry out the test and display the test result. If the test result meets the requirements, the green light will be on and the instrument interface will display OK, then the product airtightness is qualified; if it does not meet the requirements, the red light will be on and the instrument interface will display NG, then the product airtightness is unqualified.
- Record test results:The test results are recorded in the historical test records, categorized and stored, and can be exported via USB flash drive, supporting the docking of MES systems.
- Maintenance and upkeep:After the test, the instrument needs to be maintained and serviced to ensure long-term stable operation.
IV.Summarize
When choosing an electric shaver, understanding its airtight performance and related testing programs will help consumers make an informed purchasing decision. With an electric shaver that has a waterproof rating of IPX7 or higher, consumers can be assured that they can use their electric shavers not only to get a comfortable experience in their daily shaving, but also to enjoy a perfect shaving experience with greater ease in terms of cleaning and maintenance.
By understanding the airtightness testing program for electric shavers, consumers can choose a product with good airtightness performance to ensure comfort and safety during the shaving process.
