Description

A kind of electric toothbrush

Technical field

This utility model relates to a kind of apparatus that cleans one's teeth, and relates in particular to a kind of electric toothbrush.

Background technology

Along with science and technology development, daily life tools also tends to technicalization day by day.People every day must with the apparatus that cleans one's teeth also by the manual toothbrush in past, develop into the electric toothbrush of today.At present, the general electric toothbrush of using as shown in Figure 2.Its shortcoming has two: the first, and water resistance is relatively poor.Adopt 231 pairs of motors 23 of motor seal circle to seal, during use, the rotation of stretching into the major axis 211 of head toothbrushes 22 parts can make that 231 sealings of motor seal circle are unreliable, and the water capacity easily enters motor 23, causes motor 23 normally not use.The second, head toothbrushes 22 rotates with frequency with motor 23, and cause following defective: at first, output torque is lower, and the process of brushing teeth dens in dente brush rotating part is stuck easily or reduce amplitude of fluctuation significantly, causes cleaning capacity to reduce greatly, and cleaning effect is relatively poor; Secondly, motor needs enough big electric current, and with the satisfied power that drives the rotation of head toothbrushes rotating part, thereby power consumption is bigger, wastes energy; Once more, motor is under the higher load condition always and uses, and causes motor to reduce greatly service life.

The utility model content

The technical problem that this utility model embodiment will solve is, a kind of electric toothbrush of waterproof is provided.

In order to solve the problems of the technologies described above, this utility model embodiment provides a kind of electric toothbrush, comprises handle 11, head toothbrushes 12, and motor 15 and the electromagnetic actuator device 13 that is used to drive bristle 121 rotations on the head toothbrushes 12 is characterized in that:

Handle 11 is a hollow structure, and its first end near head toothbrushes 12 seals fully;

Electromagnetic actuator device 13 comprises the Magnetitum 131 that is fixed on the handle Magnetitum seat 111, and is fixed on the Magnetitum 132 on the head toothbrushes Magnetitum seat 122;

Handle Magnetitum seat 111 and Magnetitum 131 are arranged on the first end inside of handle 11, and head toothbrushes Magnetitum seat 122 and Magnetitum 132 are arranged on the first end outside of handle 11, and Magnetitum 131 is relative with Magnetitum 132;

Magnetitum 131 rotates under the driving of motor 15, and Magnetitum 131 rotates the changes of magnetic field that causes and drives Magnetitum 132 rotations, thereby drives bristle 121 rotations on the head toothbrushes 12.

Further, described electric toothbrush also comprises gear-box 14, and described gear-box 14 comprises a plurality of gears 141, described a plurality of gears 141 be used to slow down rotating speed of bristle 121 rotations.

Further, described head toothbrushes 12 also comprises major axis 123, is fixed on the driving lever 124 on the described major axis 123, hair brush base 125 and be fixed on reference column 126 on described hair brush base 125 lower surfaces;

The position of described driving lever 124 on described major axis 123 is relative with described reference column 126;

Described bristle 121 is arranged on the upper surface of described hair brush base 125.

Further, second end away from head toothbrushes 12 of described handle 11 is provided with opening, and the hollow part is provided with the battery component 112 of packed battery successively from second end to first end, motor 15, gear-box 14 and handle Magnetitum seat 111.

Further, described handle 11 outer surfaces are surrounded by flexible glue, and described flexible glue is provided with slip-proofing device.

Preferable, the second end opening place of described handle 11 is provided with bonnet 113, and described bonnet 113 seals with " O " RunddichtringO 114 with the contact position of handle 11.

Implement this utility model embodiment, have following beneficial effect: the first, because that end of the close head toothbrushes of handle seals fully, water proofing property is safe and reliable.When using, water can not enter handle inside along head toothbrushes, has ensured the normal use of motor and battery.The second, adopt the slow down rotating speed of bristle rotation of gear-box, make its rotational frequency that is lower than motor, its advantage is as follows: at first, output torque is higher, and the rotation dynamics of bristle is bigger in the process of brushing teeth, and cleaning effect is good, the cleaning efficiency height; Secondly, because the bristle rotating speed is less than motor speed, motor load is less, and consumed current is little, and efficient low-consume in the service life of improving product simultaneously, belongs to energy-conservation joint source case.
