Toothbrush is an indispensable thing in our lives. Every day we use toothbrush to clean the dirt on our teeth.Today, with the rapid advancement of technology, electric toothbrushes have become a hot new product, and electric toothbrush waterproof and air tightness testers have also become the role pursued by various businesses. It is reported that electric toothbrushes must have a certain degree of waterproofing, and waterproofing is also an important indicator that determines their service life.The waterproof performance of electric toothbrushes generally must meet IP66, IP67 or even higher waterproof levels;

Traditional detection principle
When it comes to waterproof testing, the first thing that comes to mind is traditional water immersion testing.Since the casings of electric toothbrushes are opaque, they need to be opened to check their performance after being soaked in water, and then reassembled intact. Employees may also cause assembly errors during assembly, thereby losing the waterproof function.Cumbersome procedures lead to inefficiency.
Hairis Technologyhas been committed toElectric toothbrush air tightness testerR&D and production, and has conducted a large number of electric toothbrush air tightness and waterproof grade test experiments, and has accumulated rich technical experience.Use compressed air instead of water detection; use gas attenuation method and pressure drop method to detect whether there will be water leakage.
The steps for electric dental waterproof testing are as follows:
Whether it is IP66 waterproof testing, IP67 waterproof testing, or a higher level waterproof testing, the steps are similar, but the parameter settings are different;
1. When using a waterproof detector for testing, a set of sealing molds need to be made according to the appearance characteristics of the product.
2. Fix and seal the electric toothbrush to form the detection end mentioned above.
3. Set the corresponding parameters, such as inflation time, inflation pressure, test time, test pressure, etc.
4. Place the electric toothbrush in a sealed tooling, start the waterproof detector for testing, and find out the maximum allowable leakage value of the electric toothbrush (within the allowed range)
5. If there are no other problems, the batch waterproof and air tightness test of electric toothbrushes can be carried out.
