Abstract

The utility model discloses a novel electric toothbrush which comprises a brush part, a handle shell, a support, a driving circuit and a pendulous device. One end of a swing connecting rod in the pendulous device is a permanent magnet, and the other end thereof is a flat structure and is connected with the brush part; and the brush part can be taken out freely. Two silicon sheets are vertically arranged at both sides of a coil and are fixed together by a die sleeve so as to from a groove; the permanent magnet is arranged in the groove. Both ends of the permanent magnet are respectively sheathed with a ball bearing which is fixed in a bearing support. The bearing support and the die sleeve are connected by a bolt, thus fixing the swing connecting rod, the coil and the silicon sheets together; and the swing connecting rod swings with the two ball bearings as the pivot. The pendulous device adopted by the toothbrush has rapid swing rapid and low power consumption; a tap position control module arranged on the driving circuit can realize different shaking frequencies so as to be suitable for different people; and the brush part can be freely taken out and is convenient to replace.

Description

A kind of electric toothbrush

Technical field

This utility model belongs to a kind of toothbrush, refers to a kind of novel electric toothbrush especially.

Background technology

Toothbrush has become requisite cleaning of teeth instrument in people's daily life, use habit according to different crowd, toothbrush is configured to different shapes and pattern, just have corrugated, smooth shape, softish, firmlyer etc. such as the bristle of brush portion, that handle just has is arcual, corrugated, straight clavate etc.These toothbrushes mostly are manual toothbrushs, and it is not too convenient to use.And for some electric toothbrushes, because it is to be driven by motor, the toothbrush velocity of vibration is slow, and power consumption is big, does not reach the purpose of energy-conserving and environment-protective.

The utility model content

At the deficiency that above technology exists, this utility model provides a kind of electric toothbrush, and the pendulous device that this electric toothbrush had can effectively address the above problem.

The technical scheme that this utility model is taked is as follows:

A kind of electric toothbrush comprises brush portion, handle casing, support, drive circuit and pendulous device.Described pendulous device comprises swinging connecting rod, coil, die sleeve, stalloy, ball bearing and bearing spider, and wherein, an end of swinging connecting rod is a permanent magnet, and the other end is a flat structure, and this end is connected with brush portion, and brush portion can freely be taken out.Two stalloys are erected at the both sides of coil, are fixed together with a die sleeve, thereby form a groove, and permanent magnet just places in this groove.Each sheathed ball bearing of the two ends of permanent magnet, ball bearing then is fixed in the bearing spider.By screw bearing spider and die sleeve are coupled together, thereby swinging connecting rod, coil and stalloy are fixed together, swinging connecting rod is that fulcrum can be swung with two ball bearings.

Pendulous device places internal stent, and the outfan and the coil of drive circuit couple together by lead, and its input then is connected to power supply, and power supply also places in the support.Handle casing is coated on outside the support, forms airtight the connection with brush portion.

Drive circuit comprises the gear control module, can adjust control to the vibration frequency of pendulous device.

The beneficial effects of the utility model are: the pendulous device that is adopted, and its swing speed is fast, power consumption is low; The gear control module that drive circuit is provided with can realize different vibration frequencies, uses to be fit to different people; Brush portion can freely be taken out, and it is convenient to change.

Description of drawings

Fig. 1 is an explosive view of the present utility model;

Fig. 2 is the stereoscopic figure of the pendulous device in this utility model.

Among the figure:

10 swinging connecting rods, 20 ball bearings,

30 bearing spiders, 40 stalloys,

50 die sleeves, 60 coils,

70 drive circuits, 80 supports,

90 handle casings, 100 brush portions,

101 permanent magnets.

The specific embodiment

Below in conjunction with accompanying drawing this utility model is further described:

Explosive view of the present utility model as shown in Figure 1, among the figure, a kind of electric toothbrush comprises brush portion 100, handle casing 90, support 80, drive circuit 70 and pendulous device.Described pendulous device comprises swinging connecting rod 10, coil 60, die sleeve 50, stalloy 40, ball bearing 20 and bearing spider 30.

Wherein, an end of swinging connecting rod 10 is a permanent magnet 101, and the other end is a flat structure, and this end is connected with brush portion 100, is provided with the slotted eye suitable with this flat structure in the brush portion 100, when swinging connecting rod 10 swings, can drive brush portion 100 and swing together.Brush portion 100 can freely be taken out, and is convenient to change.Two stalloys 40 are erected at the both sides of coil 60, are fixed together with a die sleeve 50, thereby form a groove, and permanent magnet 101 just places in this groove.Each sheathed ball bearing 20 of the two ends of

permanent magnet

101,20 on ball bearing is fixed in the bearing spider 30.By screw bearing spider 30 and die sleeve 50 are coupled together, thereby swinging connecting rod 10, coil 60 and stalloy 40 are fixed together, swinging connecting rod 10 is that fulcrum can be swung (referring to Fig. 2) with two ball bearings 20.Described pendulous device places support 80 inside, and the outfan of drive circuit 70 and coil 60 couple together by lead, and its input then is connected to power supply, and power supply can adopt chargeable No. five aneroid battery of a joint, also places in the support 80.Handle casing 90 is coated on outside the support 80, forms airtight connections with brush portion 100, and toothbrush inside is infiltrated at the place, slit that the Shi Shuicong that prevents to brush teeth connects.Drive circuit 70 comprises the gear control module, can adjust control to the vibration frequency of pendulous device.By the software setting, can be divided into slow, in, fast three gears, people are switched described gear by a button, select to be fit to the vibration frequency of oneself, brush teeth, so this electric toothbrush can be applicable to different people again.Also comprise charging module and indicating module in the drive circuit 70, when the electric energy of power supply exhausted soon, indicating module showed the signal of respective electrical quantity not sufficient, and the user only needs toothbrush is inserted in the corresponding charging socket, and toothbrush can charge voluntarily.Situations such as indicating module can also be indicated current use gear, and charging is full.

Be described with regard to its operation principle below:

Open switch, circuit turn-on, electric current flows into drive circuit 70, drive circuit 70 converts the unidirectional current of input to the high frequency alternating current, the high frequency alternating current flows into the coil 60 in the pendulous device, makes the magnetic field that changes around the coil 60, by the principle of electromagnetic induction, permanent magnet 101 on the swinging connecting rod 10 can be subjected to different active forces and wiggly high-frequency vibration takes place, and then drive brush portion 100 is carried out wiggly high-frequency vibration.Because the controllability of pendulous device is better, swinging connecting rod 10 need not carry out the rotation of a circumference as motor, only need carry out low-angle swinging, so vibration frequency is very high, speed is very fast, and power consumption is very low.By pressing the gear switch key, change the electric current of drive circuit 70 input coils 60, can realize the change of vibration frequency.

Certainly, above embodiment just is explanation rather than restriction this utility model, the above only is preferred embodiment of the present utility model, so all equivalences of being done according to the described method of this utility model patent claim change or modify, is included in this utility model patent claim.
