Waterproof and breathable (moisture-permeable) materials: also known as breathable materials (breathable fabrics, breathable paper, etc.), which can prevent liquid water from passing or penetrating, while being breathable. Materials that have passed through gas (or water vapor).
In the field of electronic and electrical appliances, Teflon waterproof and breathable membrane is very resistant to water, salt and The film can prevent the occurrence of condensation to the greatest extent due to the influence of other corrosive liquids, and at the same time allows water vapor to pass through. It can quickly achieve pressure balance inside and outside the shell to reduce the stress on the shell sealing strip and is easy to maintain. It can be applied to electronic products that may come into contact with water, such as electric toothbrushes, electric shavers, bathroom control boxes, lighting fixtures, vacuum cleaners, cameras, sports watches, waterproof mobile phones, and waterproof electronic scales.
Electric toothbrushes need to touch water frequently in practical applications, so they are more afraid of leakage or damage after water enters the toothbrush. Therefore, waterproofing is the key to electric toothbrushes. Today we will learn how to design the waterproof structure of electric toothbrushes! Electric toothbrushes have a waterproof structure, generally using waterproof fasteners, waterproof seals and Teflon waterproof and breathable membrane to achieve waterproofing. Under normal circumstances, if the electric toothbrush is IPX5 waterproof or above, it can be rinsed briefly under the faucet. If it reaches IPX7 waterproof, it can be used in the shower. Electric toothbrushes on the market are now generally 7-level waterproof, and only some entry-level manufacturers still have IPX5-level models.
Teflon waterproof and breathable membrane is a polymer film that can both waterproof and balance pressure, which can effectively improve the product’s durability Reliable, the protection level can reach IPX8, which is the best protection method for electric toothbrushes. Using the developed microporous waterproof membrane can effectively prevent pollution, dust and water from entering the electric toothbrush. At the same time, it can be soaked in 1 meter of water for 30 minutes without water entering! In addition, the product’s unique high air permeability ensures proper ventilation, pressure balance, and reduces pressure at the seal!
