There are articles focusing on waterproof inspection of electric toothbrushes.Here, this article simply disassemble the structure of electric toothbrush and reveals the electric toothbrush cost. Is there any difference between electric toothbrushes with different prices?
First of all, the OEM electric toothbrush varies from region to region. Jiangsu and Zhejiang provinces take the price route, and low prices can be achieved in Jiangsu and Zhejiang provinces, while the Guangdong province pays more attention to quality, so factories in this area are more export-oriented.
Secondly, the difference between the main components of the Electric toothbrush affects the electric toothbrush cost.
Electric toothbrushes generally using medium-soft bristles and many brands use DuPont bristles. The rounding rate of bristles is a key point. The National standard stipulates that the rounding rate of bristles of toothbrushes must exceed 60%, and toothbrushes that do not exceed 60% are all substandard products. Because the bristles that are not rounded easily hurt the gums, and the bristles that are too thin at the top are not enough to clean up the dirty things in the tooth gap.
In addition, some bristles are designed in a three-dimensional way, which cannot be achieved by one-time, requiring 2-3 times of bristle planting process, which is also the difference for the electric toothbrush cost.
The most important part of electric toothbrush is the motor. The motor of electric toothbrush is divided into DC motor, hollow cup motor and magnetic suspension motor.
The DC motor, if electric toothbrush cost around 20RMB, may be this kind of motor. Generally, this kind of motor does not have over-voltage and over-current protection. It may have potential safety hazards, or it may break down accidentally when it falls.
Hollow cup motor, this kind of motor is better than DC motor, the electric toothbrush sells around 100RMB is to use this kind of motor, safety is more guaranteed, but this kind of motor is generated by the friction inside the machine parts, due to physical friction, the whole motor inside starts to rotate, it drives the whole toothbrush to start vibrating, and the noise is obvious, however, some intimate manufacturers may add some vibration reduction and noise reduction devices.
Magnetic suspension motor, this is probably Vacheron Constantin in the electric toothbrush motor, right?
Magnetic suspension motor uses contactless magnetic bearings to avoid power loss caused by friction. At present, many middle and high-end electric toothbrushes use magnetic suspension motor as they can accept higher electric toothbrush cost. Because the inside moves through a magnetic field without physical friction, it will not drive the whole toothbrush to start vibrating, the noise is not obvious, and it is not easy to hemp hands.
The vibration frequency determines the cost of the motor and also affects the overall ELectric toothbrush cost, which is proportional. Of course, some merchants in the market also reported false data, saying that their vibration frequency was very high, but in fact they could not reach it. During the comparison of electric toothbrushes in the laboratory test, some brands were indeed false.
If Electric toothbrush cost is cheap, dry batteries are often used, and is not equipped with batteries when purchased. But this kind of electric toothbrush is cheap to buy and not cheap to use. Basically, batteries need to be replaced often. Moreover, it is not waterproof enough to be completely enclosed. This is especially not recommended by children. The electric toothbrush waterproof inspection has been published before. At present, rechargeable batteries are basically lithium batteries. Battery capacity determines battery life and battery cost.
Some handles of electric toothbrushes are prone to mildew, while others are especially easy to clean without mildew. The cost of nano antibacterial materials is different from that of common materials. Moreover, there is a big difference in painting. Some item need to spray 2-3 times.
The higher electric toothbrush cost, is generally formed into an integral film, and the link can hardly be seen, and the edges and corners of the toothbrush are cut neatly.
To sum up, we can understand why there is a big difference in the electric toothbrush cost. The life of electronic products will also change due to different accessories. One of the great characteristics of Chinese manufacturing is to eliminate the different needs of customers to produce cheap and fine products, but it does not mean that we cannot produce high-end products, but because of cost constraints. One of the purposes of quality inspection is that buyers need to know whether the costs they bear are well reflected in the product manufacturing. The third-party inspection company not only provides pre-shipment inspection, but also provide during production inspection or production supervision in order to meet customer needs. In this way, guests can prevent batch unqualified products and correct them in time.
