The quality tests in electric toothbrush is not only directly related to the consumer’s experience, but also affects the brand’s reputation and market competitiveness. Therefore, in the process of electric toothbrush manufacturing, it is crucial to ensure the quality of the finished product.

We all know that waterproof problems and the inability to turn on and off the machine normally have always been common problems for many electric toothbrushes after using them for a period of time. So which link is wrong for these problems? Usually, in order to avoid such problems, electric toothbrush factories usually use air tightness testing equipment for air tightness testing during the manufacturing process to ensure the stable performance and long service life of electric toothbrushes. In this article, let’s take a deeper look at this test.

What is the air tightness testing equipment for electric toothbrushes?

The air tightness quality tests in electric toothbrush production is a quality test tool that can help us test the air tightness ability of electric toothbrushes. The testing process applies specific pressure and airflow to simulate a series of situations that may be encountered during daily use, such as changes in water temperature, different degrees of force, and so on. During the test, the equipment will test the air tightness ability of the electric toothbrush to ensure that it will not leak during use, thereby ensuring the quality of the electric toothbrush.

Why do we need an electric toothbrush air tightness tester?

In the modern market, various electric toothbrush brands and models continue to emerge. Although the waterproof level of most electric toothbrushes can basically meet the IPX7 standard, due to differences in manufacturing processes and materials, electric toothbrushes from different manufacturers have large differences in air tightness capabilities. Some low-quality electric toothbrushes have problems such as air leakage, water ingress, and inability to turn on after a very short period of use.
As a professional electric toothbrush manufacturer, Powsmart will use an electric toothbrush air tightness tester to test the air tightness of semi-finished or finished products after taking various waterproof treatment measures for electric toothbrushes, so as to exclude those products that do not meet the requirements for air tightness.

How to conduct an electric toothbrush air tightness test?

When doing a non-destructive electric toothbrush waterproof test, according to the shape and specifications of the electric toothbrush, we will customize the matching tooling fixture, put the electric toothbrush in and set the corresponding test parameters. The sensor in the electric toothbrush airtight waterproof tester will detect the changes in the internal air pressure value in real time. According to the set parameters, it will determine whether the electric toothbrush’s sealing meets the requirements. If there is a leak, it indicates unqualified (NG light + alarm).
There are three main steps for the airtight tester to detect electric toothbrushes: first, set the corresponding detection parameters on the electric toothbrush airtight tester; second, put the electric toothbrush into the mold test cavity of the tooling fixture; third, press the double start button on the tooling fixture at the same time and wait for the test results.

The importance of airtight testing

1. Ensure product quality
   By testing the product with an airtight tester, the tiny leak points inside the product can be accurately identified, thereby ensuring the sealing performance of the product and improving the overall quality of the product. Regular use of airtight testers can ensure production safety, reduce production losses, and ensure that the product will not be invaded by moisture or liquid during use, resulting in damage to the product.
2. High efficiency and low cost
   In the production process, after using the airtightness tester to screen out products with unqualified sealing, rework the unqualified products, which can improve production efficiency, reduce defective rate, avoid cumbersome after-sales steps, and reduce after-sales costs.
3. Optimize production process
   The airtightness tester can help enterprises optimize production processes, optimize product structure, etc. by screening out products with unqualified sealing, improve overall production efficiency, and promote the sustainable development of the enterprise’s production line.
