Chinanews client, Beijing, April 13 (Reporter Xie Yiguan) As the saying goes: "Toothache is not a disease, it hurts really badly." For consumers, the most common oral care is brushing their teeth.
Recently, the China Consumers Association conducted a comparative test of 25 electric toothbrush products of some brands sold on the Internet and found that electric toothbrushes have great differences in cleaning effects, noise, and charging and discharging time.
The picture comes from the China Consumers Association.
The cleaning performance of electric toothbrushes is the focus of consumers when purchasing. 25 samples have compared the cleaning effects of dental mold dirt. 16 samples have relatively good cleaning effects, and 4 samples have poor cleaning effects and poor cleaning effects. , Involving four brands of Royalstar, Qianshan, j-style, and Antarctica.
Noise is an important aspect to measure the quality of electric toothbrushes. The China Consumers Association has tested the maximum noise of 25 electric toothbrush samples. Among them, 4 products have a noise greater than 50 decibels. Coupled with high-frequency vibration, users feel that the noise is large. , Like the sound of a dental drill, they are Oral-B BRAUN electric toothbrush 3765, Oral-B BRAUN electric toothbrush 3766, Shuke saky Pro sonic electric toothbrush G22, ubaLun/Ubalun sonic electric toothbrush UBL-01, with a score of only 3 star.
The noise of another 14 products is less than 40 decibels, which is equivalent to the sound of a quiet conversation, and users are more willing to accept it.
The difference between the maximum noise and the minimum noise of the sample is about 25 decibels, which is quite large.
In addition, the longer the discharge time, the longer the working time of a fully charged battery and the more durable it is.
Among the 25 samples of electric toothbrushes, 5 have a discharge time of more than 8 hours, and 7 have a discharge time of 3-8 hours.
The longest discharge time measured is 21.7 hours, and the shortest discharge time is 0.7 hours, which is a huge difference.
Oral-B BRAUN, Panasonic, Shuke and other brand samples scored lower in this item.

After checking the logos and descriptions of 25 samples, the China Consumers Association found that the product logos and descriptions have some problems in the content of the label, which is not conducive to consumers' purchase.
For example, on some sample toothbrush handles, the use gear or warning information is not marked in Chinese, which is likely to cause misuse for some users, or fail to play the proper safety warning function; some toothbrush handles do not have a nameplate, Or the nameplate can be easily removed, or the nameplate lacks product information, which cannot guide the user to use the electric toothbrush correctly and safely.
Among the 25 samples, only 2 samples with the name "Oral-B BRAUN" clearly stated the noise level; 9 samples rated the vibration frequency of the toothbrush in use, with values ranging from 28,000 to 42,000 times per minute.
All samples performed well in inspection items such as the quality of bristles, the firmness of the connection between the brush head and the handle, and the number of times the switch button was used.
