What Are the Common Electric Toothbrush Inspection Items?
As people’s awareness of oral health care continues to increase, a new type of toothbrush, the electric toothbrush, has quietly entered people’s daily lives. Compared with traditional toothbrushes, electric toothbrushes do have many advantages. Its reasonable exercise program can correct some people’s incorrect brushing methods, and some use high-tech designed functions such as sonic vibration function to clean the mouth more effectively.
Because the product is relatively new and has been relatively minority in the past, the product standard of electric toothbrushes has been missing. At present, China only has the production standard of ordinary toothbrushes. CLI company has analyzed the toothbrush defect check but there is no national standard for electric toothbrushes, the verification of its effect is only preliminary results obtained through clinical observation.Electric toothbrush manufacturers have different definitions of products and product performance indicators are not uniform, according to Why are the price ranges of electric tooth brushes so different ,there are many reasons for the great difference in the price of electric toothbrushes, including the manufacturing level, the cost of manufacturing.There are also price differences caused by different functions and performances. For example, the manufacturing cost of dry battery products is relatively low, and the product price is low. The manufacturing cost of the charging device of the rechargeable electric toothbrush is higher, resulting in higher product price. Since each enterprise manufacture according to own standard,the electric toothbrush inspection is mainly entrusted by the enterprise and performed in accordance with their own enterprise standards.
CLI, as a professional third-party inspection company,referring to the national mandatory standard GB4706.59-2002 “Special Requirements for Oral Hygiene Appliances” , formulates the standard for our own electric toothbrush inspection.
