Electric sonic toothbrush special sealing tester

The big problem of electric toothbrush is that the sealing is not good, and the water is the big problem of maintenance. The culprit that causes the water to enter is the sealing ring. The current mainstream sonic toothbrush is waterproof by the sealing ring. There are about four kinds of sealing rings, all of which are made of rubber material. Because of the characteristics of rubber itself, it is easy to mold and aging, and then it will lose its original elasticity, which will become hard and brittle, causing cracks and water intrusion. The main board is corroded, causing electrical failure.

Therefore, the sealing test of the electric sonic toothbrush becomes an important process for each common product before leaving the factory. How to operate it is a small series for you to analyze the parameters and usage of the electric sonic toothbrush negative pressure seal tester.

Product Name: Special Sealing Tester for Electric Sonic Toothbrush

Electrosonic Toothbrush Special Sealing Tester Experimental Principle: Electric Sonic Toothbrush Negative Pressure Sealing Tester is a kind of sealing method for detecting the electric toothbrush by using compressed air to generate negative pressure through the vacuum original set.

By vacuuming the vacuum chamber, the electric sonic toothbrush immersed in water generates internal and external pressure difference, and the gas escape or water infiltration of the electric sonic toothbrush in the vacuum chamber is observed to determine the sealing performance of the test sample.

Technical specifications of special sealing tester for electric sonic toothbrush :

1 Measuring range: -90┄0KPa (Note: display pressure, display positive value)

2 Measurement accuracy: Level 1

3 Test tube inner product: φ270mm × 200 mm

4 Average air consumption: 70L/min

5 Net weight of equipment: 10kg

6 Self-contained stable compressed air source

7 Compressed air pressure range: 0.7~1.0 Mpa

Structural features: mainly composed of special transparent vacuum chamber (plexiglass barrel), vacuum generation system, compressed air source (customer self-provided gas source outlet pressure is 0.7-1.0 MPa), pressure gauge and so on.

The main part is mainly composed of a solenoid valve, a vacuum conversion device and a pressure sensor. The PLC is controlled by the opening and closing of the solenoid valve to control the input and output of the pressure to realize different test processes. At the same time, it accurately displays the pressure and holding time of the container.
