Description
Technical field
The present invention relates to appliance for personal care fields, more specifically, are related to electric toothbrush.
Background technology
Electric toothbrush is often desirable to while volume reduces as far as possible, can have stronger vibration and above-mentioned vibrational energy
It is enough to be driven as far as possible to toothbrush head without being transmitted to handle portion.However vibrating motor is arranged in hand for general electric toothbrush
In handle, vibrating motor is stretched out by a metal shaft from handle from inside to outside, plugs toothbrush head in above-mentioned metal shaft, this makes electricity
Dynamic toothbrush is difficult to control volume, and is unfavorable for reducing the vibration to transmission at handle.
In this regard, also having the electric toothbrush of motor preposition in the market, for details, reference can be made to Chinese Patent Application No.
" CN201010188777.7 ", structure disclosed in the patent of invention of entitled " sound wave vibration structure of electric toothbrush ".It is above-mentioned
In toothbrush, by the way that vibration source (vibrating motor) to be set up directly on to the front end of drive link, toothbrush head is plugged outside drive link, because
This can allow vibration only to be transmitted as far as possible to brush head direction, final so that the vibration sense on handle reduces.
However, in above structure, due to needing that motor is arranged in drive link, the volume of drive link is difficult to decrease,
Motor can only use miniaturization, low power motor, so that the vibration of toothbrush head is difficult to reach required for adult brushes teeth
Standard.Furthermore, it is necessary to which specially setting lead connects motor with the control circuit board in handle, when in use due to drive link
In high-frequency vibration state, above-mentioned lead is often following drive link to vibrate together, this makes the link on lead and wiring board
Whether solder joint is easy to fall off.
Based on problem above, it is necessary to be improved to the prior art.
Invention content
It is an object of the invention to overcome the deficiencies of the prior art and provide electric toothbrushes.
The present invention is achieved through the following technical solutions：Electric toothbrush main body, including handle, in one end of the handle
It is provided with opening, the open end is provided with drive link, the drive link includes cavity, and one end rotation of the cavity is provided with
Pendulum is integrated with the first Magnetic drive wheel on the pendulum, further includes a connecting shaft, one end of the connecting shaft is provided with face institute
The second Magnetic drive wheel of the first Magnetic drive wheel is stated, the other end of the shaft is provided with third Magnetic drive wheel, is set in the handle
It is equipped with motor, is provided with the 4th Magnetic drive wheel on the output shaft of the motor, the 4th magnetic described in the third Magnetic drive wheel interval
Driving wheel is arranged.
In above-mentioned technical proposal, retainer is provided in the cavity, the connecting shaft rotates branch by the retainer
It holds.
In above-mentioned technical proposal, there is a circle annular wall in the end set of the handle and drive link cooperation, in institute
The one end for stating drive link is provided with block, and notch is offered in the annular wall, and the block is located in the notch, and and
The slit space cooperation.
In above-mentioned technical proposal, it is arranged at intervals with first seal and second seal below the drive link, institute
State the top that first seal is located at the second seal, the first seal and the second seal and the annular
It is interference fitted between the inside of wall.
The present invention has the advantages that：1) motor of the present invention is still located at handle inner, therefore with adequately empty
Between motor is installed, motor can be set to have high-power and can further reduce transmission rod volume；2) present invention electricity
Machine final pendulum driven positioned at one section of drive link by way of Magnetic drive, therefore, even if not stopping in movement in drive link
In the process, the drive mechanism between motor and pendulum can be still kept not to be interfered.
Description of the drawings
Fig. 1 is the overall structure diagram of the present invention.
Fig. 2 is along the sectional view at A-A in Fig. 1.
Specific implementation mode
Present invention is further described in detail with specific implementation mode below in conjunction with the accompanying drawings：It is electronic referring to Fig. 1 to Fig. 2
Toothbrush, including handle 1, one end of the handle 1 is provided with opening, the open end is provided with drive link 2, the drive link
2 include cavity 20, and one end of the cavity 20 is fixedly installed shaft 3, is rotated in the shaft 3 and is provided with pendulum 4, described
It is integrated with the first Magnetic drive wheel 5 on pendulum 4, further includes a connecting shaft 6, one end of the connecting shaft 6 is provided with described in face
The other end of second Magnetic drive wheel 60 of one Magnetic drive wheel 5, the connecting shaft 6 is provided with third Magnetic drive wheel 61, the handle 1
It is inside provided with motor 7, the 4th Magnetic drive wheel 70, the third Magnetic drive wheel are provided on the output shaft of the motor 7
61 intervals and the 4th Magnetic drive wheel 70 setting.Matched by the Magnetic drive between the first, second, third, fourth driving wheel 7
It closes, finally so that the 4th Magnetic drive wheel 70 drives the pendulum 4 to rotate, the rotation of pendulum 4 forms shaking for drive link 2 in turn
It is dynamic.
Further, fulcrum bearing (attached drawing is not shown), the connecting shaft 6 are inserted in the cavity 20 of the drive link 2
By the fulcrum bearing rotating support.The open end of the handle 1 is provided with a circle annular wall 10, in one end of the drive link 2
It is provided with block 21, notch 10a is offered in the annular wall 10, the block 21 is located in the notch 10a, and and institute
State notch 10a clearance fits.In above structure, in artificially twisting drive link, due to the cooperation of block 21 and notch 10a, make
Wide-angle will not be twisted by obtaining drive link；Further, since block 21 and notch 10a are gap-matched, therefore it ensure that biography
Lever can generate normal vibration, and be unlikely to transmit excessive vibration at handle.
It is arranged at intervals with first seal 8 and second seal 9, the first seal 8 positioned at 2 lower end of the drive link
Positioned at the top of the second seal 9, between 1 inside of the first seal 8 and the second seal 9 and the handle
Interference fit, more specifically, is interference fitted between the inside for the annular wall 10 being arranged on handle 1.Wherein described first is close
Sealing 8 uses O-ring, the second seal 9 that gas-flow closure circle, the gas-flow closure circle is used to have and can be connect with the external world
Air inflation nozzle (attached drawing is not shown).In above structure, all by the first seal 8 by the stable transmission on the handle,
The deflection angle of the drive link 2 is controlled by controlling the gas flow in the second seal 9, this makes electric toothbrush
Motor output frequency can readily be adjusted to it is consistent with the intrinsic frequency of total.
