Problems solved by technology

[0005] At present, most of the toothbrush filaments used in the above toothbrushes are commonly used nylon hair or DuPont hair, and the grinding and cleaning efficiency between the teeth and the teeth is low, and the purpose of fast tooth cleaning cannot be achieved, and it cannot be compared with the manual tooth cleaning and ultrasonic cleaning commonly used in hospitals. teeth cleaning methods compared
In addition, the surface of some existing toothbrush filaments is completely covered by the toothbrush filament matrix, or fine sand is used, the surface is smooth, the friction value is low, the grinding and cleaning efficiency between teeth and teeth is low, and it is difficult to effectively remove tartar. It does not have a good friction effect, nor can it achieve the effect of fast descaling and fast tooth cleaning
At present, the manual tooth cleaning and ultrasonic tooth cleaning methods commonly used in hospitals can generally complete tooth cleaning in 1 to 3 hours, and the efficiency is also low.

[0095] Specifically, nylon toothbrush wire is used as the toothbrush wire body 4, and a layer of polyurethane adhesive 6 is first coated on the outer surface of the nylon toothbrush wire, and then the 1000-mesh silicon carbide powder abrasive material particles 5 are evenly covered on the to...

Embodiment 2

[0103] This embodiment provides an electric toothbrush, which is different from Embodiment 1 in the toothbrush head;

[0104] In this embodiment, PBT toothbrush wire is used as the toothbrush wire body. First, a layer of polyacrylic resin adhesive is applied to the outer surface of the PBT toothbrush wire, and then 1000 mesh corundum powder is evenly covered on it, compacted, and obtained after heating and curing. Descaling toothbrush filaments with particles of abrasive material on their surface.

[0105] The electric toothbrush head contains a mouthwash input device and a hollow channel, and the electric toothbrush matched with the electric toothbrush head is used to brush teeth, and the cleaning of the tooth surface can be completed within 2 hours. The final effect is as follows: Figure 9 shown.

Embodiment 3

[0107] This embodiment provides an electric toothbrush, which is different from Embodiment 1 in the toothbrush head;

[0108] In this embodiment, PBT toothbrush wire is used as the toothbrush wire body. First, a layer of epoxy resin adhesive is coated on the outer surface of the PBT toothbrush wire, and then 1500 mesh emery powder is evenly covered on it, compacted, and obtained after heating and curing. Descaling toothbrush filaments with particles of abrasive material on their surface.

[0109] The electric toothbrush head contains a mouthwash input device and a hollow channel, and the electric toothbrush matched with the electric toothbrush head is used to brush teeth, and the cleaning of the tooth surface can be completed within 1 hour, and the final effect is as follows: Figure 9 shown.

Description

technical field [0001] The invention belongs to the field of toothbrushes, in particular to an electric toothbrush. Background technique [0002] Toothbrush, as an indispensable tooth cleaning and nursing tool in people's daily life, is in closest contact with the oral cavity. In recent years, electric toothbrushes have been used more and more widely. Compared with manual (non-powered) toothbrushes, the advantages of electric toothbrushes are that they move the bristles at a higher speed than can be achieved manually. Movements of different types and directions. These movements, often in conjunction with the manual movements of the user, provide a better cleaning than a manual toothbrush. [0003] Electric toothbrushes generally clean teeth by vibration, rotation or swing, and some are also equipped with ultrasonic instruments, which clean teeth by pulse and water spray. Ordinary electric toothbrushes that sell for tens of yuan on the market just clean teeth by simple vib...
