What is the electric toothbrush's technology and principle

The electric toothbrush is a kind of toothbrush invented by Philippe-Guy Woog. The rapid rotation or vibration of the electric movement can make the brush head generate high-frequency vibration, instantly decompose the toothpaste into fine foam, and deeply clean the teeth. At the same time, the vibration of the brush can promote the blood circulation in the mouth and massage the gingival tissue.

Electric toothbrushes have revolutionized oral health care in foreign countries.

What is the electric toothbrush's technology and principle

The technology principle

In principle, there are two categories of electric toothbrushes: rotation and vibration. The principle of rotary toothbrush is simple, that is, the motor drives the circular brush head to rotate, which can enhance the friction effect while performing the common brushing action. Rotary toothbrush is noisy, and the cleaning of tooth surface is very clean, and the cleaning of tooth gap is relatively weak. Vibrating toothbrushes are more complex and more expensive. Vibration type of toothbrush has a vibration motor driven by electricity, which can make the brush head produce high frequency oscillation perpendicular to the direction of the brush handle, but the amplitude of oscillation is very small, generally up and down about 5 mm, the industry's largest amplitude is 6 mm. When brushing teeth, on the one hand, the high-frequency head of the brush can effectively complete the movement of brushing teeth, on the other hand, more than 30,000 times per minute of vibration also let the mixture of toothpaste and water in the mouth produce a large number of tiny bubbles, bubbles burst when the pressure can be deep into the teeth to clean dirt.

Structural characteristics

There are three types of motion mode of electric brush head: one is reciprocating linear motion of brush head, one is rotating motion, and one is a complete set of electric toothbrush with two kinds of brush heads. The bristles of the toothbrush head are made of soft plastic fiber, and the bristles are processed into spherical shapes, which will not damage the teeth and gums, nor affect the brushing effect. Can brush every tooth not only clean, and still have massage effect to gum. There are strong and weak switching mode switches on the toothbrush handle, which can select the movement speed of the toothbrush head according to personal needs. In the past few years, quite a few dentists have started to recommend electric toothbrushes to their patients. An electric toothbrush is a tool for cleaning teeth. It consists of a rechargeable dry battery, a miniature dc motor, a battery case, a toothbrush head, a metal guard plate and a sleeve. The dry battery, as the power source of the dc motor, is installed together with the dc motor in the battery box, which is provided with a manual switch to control the power supply on and off of the dc motor. The rotating shaft of the dc motor extends out of the battery box. The toothbrush head and the metal guard plate are set on the rotating shaft of the dc motor. The toothbrush head and the metal guard plate have a set of tubes. Electric toothbrush with a variety of different models of toothbrush head can be applied to a variety of users.

 

In addition to daily brushing, it can also be used to massage the gums. It can be used for both manual and electric brushing, and can be used for both vertical and horizontal brushing. Gingiva can enhance blood circulation by rhythmically tapping and rubbing, and it is better to enhance the absorption effect of gingiva with medication. For periodontitis, gingivitis, gingival bleeding and other common dental disease has a very good treatment and prevention. Use this brush to change from horizontal to vertical brushing. When brushing by hand, use the same method as a regular toothbrush.

Brush Wool The brush wool of electric toothbrush is nylon silk more commonly, nylon silk brush wool is fine and soft, wear-resisting, not bibulous. And the company that invented nylon silk is American dupont, so good electric tooth brush brush wool USES dupont silk more.

Brush wool hardness Brush wool presses soft hard degree to differ, clean the effect also can differ somewhat, too soft brush is to do not have method to clean dental plaque very well. Hard bristles have good cleaning power, but too hard bristles and easy to cause gingival recession, tooth neck wedge defect, etc.. We generally recommend fine bristles for children, but for people who smoke a lot, or who have dental stones, it's natural to recommend a stiff brush, because the cleaning effect is definitely higher. And average person, the proposal chooses soft the bristle with moderate hardness can.

Bristle modelling The structural modelling design of tooth brush brush head also concerns with clean effect, because it is the key that stereo cleans. Only high fitting, with as much cleaning area as possible and ideal cleaning depth, can give full play to the teeth brush head maximum cleaning effectiveness. A w-shaped bristle goes deeper into the back of your mouth to help clean your teeth.

Brush head material Material should be good brush head material TPE soft plastic package, TPE has environmental protection, non-toxic safety, so that when you brush your teeth will not because the brush head too hard to hurt the internal mouth.
