The China Consumers Association released a comparative test report on 25 electric toothbrushes on the 13th. The maximum noise of the samples exceeded 50 decibels, and the user felt like a dental drill. In addition, the charging and discharging times of the samples vary greatly. The actual charging time is the shortest 1.4 hours and the longest 29.5 hours; the longest discharge time is 21.7 hours and the shortest discharge time is only 0.7 hours.

Noise is an important aspect to measure the quality of electric toothbrushes. Excessive noise can make users irritable and is also the reason why some consumers cannot accept electric toothbrushes. The noise of electric toothbrushes is mainly caused by the high-speed vibration of the internal motor. The experiment tested the maximum operating noise of 25 electric toothbrush samples. The test results showed great differences. The difference between the maximum noise and the minimum noise was about 25 decibels. Among them, 4 products have a noise greater than 50 decibels, coupled with high-frequency vibration, which makes users feel that the noise is loud, like the sound of a dental drill; 14 products have a noise less than 40 decibels, which is equivalent to the sound of a whispered conversation, and users are more willing to accept.

The cleaning performance of electric toothbrushes is the focus of consumers' attention when purchasing. The report shows that the cleaning performance of the samples varies greatly, with 3 samples reaching five stars and the sample with a rotating brush head having a better cleaning effect; 4 samples only have a two-star cleaning effect.

25 samples were purchased from Jingdong Mall, Suning.com and Tmall Mall. They are all adult rechargeable electric toothbrushes with removable brush heads. The unit prices range from 60 yuan to 1,000 yuan. The brands include domestic and foreign brands. 20 brands.

What should you pay attention to when purchasing an electric toothbrush?

[Look at the label] When purchasing, try to purchase an electric toothbrush with complete label information through formal channels. Avoid purchasing products without product name information, brand model, or warning instructions.

[Choose Type] users should choose an appropriate electric toothbrush based on age, dental condition, etc. Children should choose children's electric toothbrushes. If the user has sensitive teeth, a brush head with soft bristles can be used to reduce damage to teeth and gums.

[Test the vibration] When purchasing, pay attention to the vibration frequency of the electric toothbrush. Generally, the product with the higher vibration frequency has better cleaning effect. However, the noise and vibration in the hand will be stronger. At present, the nominal vibration of electric toothbrushes is mostly at the sonic level, with a frequency of about 20,000 to 40,000 times per minute. When buying an electric toothbrush in a physical store, you can hold the electric toothbrush in your hand and turn it to the maximum to actually feel whether the operating noise and vibration are acceptable. For some patients suffering from gingivitis and periodontitis, try not to use working modes or products with too high vibration frequencies.

[Recognition function] focuses on the functionality of electric toothbrushes, such as intelligent time reminder function, pressure sensing function, low battery reminder function, etc. The length of brushing time is directly related to the cleaning effect of the teeth. Therefore, some electric toothbrush products have added a time reminder function, which generally prompts the user to change the brushing position every 30 seconds, while ensuring that the user brushes the teeth for no less than 30 seconds each time. 2 minutes. Some users have difficulty controlling the pressure the toothbrush exerts on their teeth when using an electric toothbrush. Excessive pressure can cause the bristles to wear down your teeth and damage your gums. Therefore, some products have added pressure sensing functions. When it detects that the toothbrush exerts too much pressure on the teeth, it will automatically reduce the vibration frequency of the toothbrush to reduce damage to the teeth.

[Choose battery] When purchasing , pay attention to product battery capacity, charging time and other information. Choose the appropriate product based on usage conditions and frequency of use. (Reporter Zhao Wenjun)
