        basic introduction

        The electric toothbrush is a relatively new product. The new product that has been available only in recent years has become a new type of technical product for oral health care. Compared with ordinary toothbrushes, electric toothbrushes are more scientific and effective. It can more completely remove dental plaque, reduce oral diseases such as gingivitis and periodontal disease, and is also a popular daily necessity in many European and American countries. The rapid rotation or vibration of the electric toothbrush causes the brush head to generate high-frequency vibration, and instantly decomposes the toothpaste into fine foam to clean the teeth. With the popularity of the products, the quality inspection report of the electric toothbrush has also become a pass to enter the market. When entering the Tmall mall, electric toothbrushes also need to submit a quality inspection report that meets the requirements; a quality inspection report is also required for product acceptance. ZRLK testing is a third-party testing and appraisal agency designated by the state, which can provide you with CNAS and CMA electric toothbrush quality inspection reports.
