Description

electric toothbrush

technical field

The utility model belongs to the field of daily necessities, in particular to an electric toothbrush.

Background technique

Electric toothbrush is a new product that has appeared in recent years, and it has set off a revolution in the field of oral health care abroad. Though electric toothbrush is not still popularized in the application of my country, existing people's prediction, it will become the important a member in the popular health product. Surveys show that electric toothbrushes are more scientific and effective than ordinary toothbrushes. Can more thoroughly remove dental plaque, reduce gingivitis and gingival hemorrhage, also be the generally popular daily necessities of present European and American many countries. The electric toothbrush rotates quickly to generate high-frequency vibrations on the brush head, instantly decomposing the toothpaste into fine foam, and deeply cleans the gaps between the teeth; at the same time, the vibration of the bristles can promote blood circulation in the oral cavity and have an unexpected massage effect on the gum tissue .

In principle, there are two types of electric toothbrushes: rotation and vibration. The principle of rotary toothbrushes is simple, that is, the electric motor drives the round brush head to rotate, which enhances the friction effect while performing ordinary brushing actions. High wear and tear, not recommended for long-term use. Vibrating toothbrushes are more complex and higher-end in terms of price. There is an electric-driven vibration motor inside the vibration type toothbrush, which can make the brush head produce high-frequency swing perpendicular to the direction of the brush handle, but the swing amplitude is very small, generally about 5mm up and down, and the industry's largest swing amplitude is 6mm. mm. When brushing your teeth, on the one hand, the high-frequency oscillating brush head can efficiently clean your teeth. On the other hand, the vibration of more than 30,000 times per minute also makes the mixture of toothpaste and water in the mouth produce a large number of tiny bubbles. The pressure can go deep between the teeth to clean the dirt.

Although the electric toothbrush has been recognized by consumers since its appearance, there are still many deficiencies such as inconvenient use by users in the actual application process, and electric toothbrushes need to be improved accordingly.

detailed description

In order to make the purpose, technical solution and advantages of the utility model clearer, the technical solution of the utility model will be described in detail below. Apparently, the described embodiments are only some of the embodiments of the present invention, not all of them. Based on the embodiments of the present utility model, all other implementations obtained by persons of ordinary skill in the art without making creative efforts belong to the protection scope of the present utility model.

As shown in Figure 1-8, the electric toothbrush includes a brush head 1, a core 2 and a handle 3, one end of the core 2 is fixed in the handle 3, the other end of the core 2 is connected to the brush head 1, and the brush head 1 is set There are bristles 11, the maximum length of the cross-section of the end of the handle 3 close to the brush head 1 is greater than the maximum length of the cross-section of the end away from the brush head 1, that is, the handle 3 is in the shape of a large top and a small bottom, and the shape of the handle 3 is preferably a hollow cylinder Shape, now the maximum length of the handle 3 cross-section is the outer diameter of the handle.

The inventors found that in real life, electric toothbrushes are very easy to slip. After research, it is found that the occurrence of this phenomenon is due to the fact that the existing electric toothbrush handles are all in the shape of a small top and a large bottom. Liquids such as water, liquid toothpaste, and a mixture of water and toothpaste on the upper part of the electric toothbrush can easily flow to the handle on the lower part of the electric toothbrush, that is, the part where the electric toothbrush is in contact with the user, and the liquid can reduce the distance between the handle and the user's hand. Friction, coupled with the vibration of the electric toothbrush during use, the electric toothbrush is prone to slipping and falling off during use.

Therefore, in this application, the handle 3 is set to a structure in which the maximum length of the cross-section of the end of the handle 3 close to the brush head 1 (i.e., the upper part of the handle 3) is greater than the maximum length of the cross-section of the end away from the brush head 1 (i.e., the lower part of the handle 3), During the use of the electric toothbrush, since the maximum length of the upper cross-section of the handle 3 is greater than the maximum length of the lower cross-section of the handle 3, the upper part of the handle 3 can realize the function of diversion, and the liquid in the upper part of the handle 3 reduces the probability of sliding to the lower part of the handle 3 , thereby reducing the chance of the electric toothbrush slipping and falling during use.

On the basis of the above structure, the handle 3 can be arranged in a stepped structure, or in the following structure, the maximum length of the cross section of the handle 3 decreases successively from the end close to the brush head 1 to the end far away from the brush head 1. structure, so that the overall structure of the handle 3 is relatively smooth, which is convenient for the user to grasp and clean, and at the same time, the processing difficulty is low.

The inventors have found that when the specific parameters of the handle 3 are set as follows, the user's grip is the most comfortable state; the maximum length of the cross section of the end of the handle 3 close to the brush head 1 is 26-30mm, preferably 28mm, and the handle 3 is far away from the brush head 1. The maximum length of the cross-section of one end of the brush head 1 is 23-27 mm, preferably 25 mm, and the above-mentioned size is the most comfortable and the optimal size that can reduce the phenomenon of slipping has been verified.

For the design of the brush head 1, the brush head 1 is designed as an arc on the side provided with the bristles 11 in this application, and the angle of the central angle corresponding to the arc is 10-15 degrees.
