    The special waterproof and breathable products of the electric brush series increase the reliability of your products and enhance the quality and image of the products
    The electric comfort quality in daily personal care products brings great convenience to life, with rotating or reciprocating methods, different power sources, waterproof performance, etc., which provide more choices for the needs of the public.
    The brush series products are distinguished by the separate design of the external structure and the function of the sealed power supply cavity, but their characteristics and principles are similar, and the heat formed by the replacement of the power supply between the components in the entire power supply cavity is different from the electric product itself. The use environment puts a test on the requirements of waterproof and breathable protection level. How to make the brush products improve the water resistance and durability?
    When electric toothbrushes and electric shavers are working, they will come into contact with liquid and penetrate the inside. Over time, some parts inside will rust and age. Long-term storage will also cause some fine dust to enter the interior, which affects electric toothbrushes and electric shavers. The razor works and may even stop working. Worry's waterproof, dust-proof and breathable products can be instantly balanced even when the internal and external pressure difference is large, preventing water and liquid molecules from penetrating to the other side, and balancing the internal and external pressure of the cavity to prevent problems. It is implemented by welding with a series of waterproof and breathable membranes. Its surface filtration is better than deep filtration, excellent filtration efficiency, dustproof rate of 99.9%, almost zero dust emission, smooth surface without condensation, easy to clean dust, good barrier effect, long service life, and easy installation.
    Wo Rui Technology specializes in providing waterproof and breathable solutions, providing high-quality waterproof and breathable products for brush series products, such as waterproof and breathable membranes, push-type products PVD series/PF series can meet the waterproof protection needs of brush series products, improve product quality and extend service life .
