Description

The electric toothbrush of architecture advances

This utility model relates to a kind of electric toothbrush.

Brushing teeth is the Personal hygiene work that we must do every day, therefore the use of toothbrush can be said so quite general, but in busy now society, as if the time enough never, therefore, make good use of the limited time, the target that has become the modern to pursue, therefore, a kind of electric toothbrush is to be catered to the epoch of seizing every minute and second like this and asks the city, and this product also possesses the brushing time of saving and makes cleaning advantage more completely except that the purpose that can reach the oral cavity cleaning, and with regard to thorough cleaning, electric toothbrush need possess the rotation that personalizes in the process of brushing teeth, advance, action such as retreat, can reach best cleaning effect, the drive mechanism of conventional power toothbrush, be to drive two cams respectively, again with the mutual pushing tow trace of the mode of shell fragment, with rotation by means of trace at the motor two ends, drive Toothbrush head cover and just fixing angle, despining, this structure ubiquity has following shortcoming:

1, fault rate height: shell fragment easily causes elastic fatigue under long term, cause the parts fault, reduces service life.

2, manufacturing is difficult for: be connected the connecting rod of swing really for making cams at two ends, the design of this cam is quite difficult, and under improper operating position, cam and shell fragment cause idle running or stuck easily.

3, take up space: kind of drive complexity, cause the increasing that takes up space, form the inconvenience of manipulating.

Therefore, main purpose of the present utility model is to provide a kind of electric toothbrush of architecture advances, mainly be in the tubular body, be provided with a drive motor, make the primary shaft of this motor articulate a gear train, and by the prominent bayonet lock of establishing on this gear, do the pushing tow action at the opening of a C type oscillating deck, make it constitute the reciprocally swinging of certain angle, pole via this oscillating deck one end connects another sector wheels, make this gear train be driven a cylinder and form forward and reverse rotation, make the toothbrush that is socketed on the cylinder sleeve form the action of brushing teeth of positive and negative rotation.

Another purpose of the present utility model is the headgear inner edge of this body and the one side of cylinder, is provided with corresponding skewback, makes cylinder when rotating, and because of the effect of these skewbacks, forms the reciprocating action of advancing, retreating, the cleaning effect of brushing teeth with increase.

The utility model proposes a kind of like this electric toothbrush, comprise a tubular body, for inserting rechargable battery, inductive charging coil, its surface is provided with cell switch; One drive mechanism, be provided with a drive motor, the primary shaft of this motor is articulated in the drivewheel of gear train after passing the central open-work of a dividing plate, and this drivewheel bridle joint is in another driven pulley, and the set bayonet lock of this driven pulley periphery passes the elongated opening of C type swing sheet; This C type swing sheet one end is provided with a pole, this pole is after passing the set through hole of a bracing frame one side, be connected in a sector gear, with bridle joint in another travelling gear, by this gear sheathed axle center after passing the dividing plate that a surface is provided with skewback, with a square block socket, the cylindrical sleeve that a forward and backward surface is provided with symmetrical skewback places on this block, is articulated with a sleeve in this cylinder the place ahead; One headgear is sleeved on the tubular body, is provided with skewback at the opening inner peripheral of its front end.

Main feature of the present utility model and novelty thereof will be by below in conjunction with the detailed description of accompanying drawing to embodiment, and it is clear more to become, as shown in the figure:

Fig. 5 B is the partial enlarged drawing of Fig. 5 A.

Please consult Fig. 1 and Fig. 2 simultaneously, this utility model mainly comprises tubular body 1 and headgear 2, wherein, can be in the body 1 for putting into rechargeable battery, electronic components such as inductive charging coil, and the switching by switch 11, to connect or to close the power supply of battery, and to a drive motor 12 power supplies, the primary shaft 121 of this motor 12 passes after the open-work 131 of a dividing plate 13, be articulated in the drivewheel 14 of a gear train, these drivewheel 14 bridle joints are in driven pulley 15, and the bayonet lock 151 that is provided with on these driven pulley 15 peripheries passes the elongated opening 162 of C type swing sheet 16, when this driven pulley 15 rotates, drive this C type swing sheet 16 reciprocally swingings.

One end of this C type swing sheet 16 is provided with a pole 161, after this pole 161 is passed the set through hole 171 of bracing frame 17 1 sides, be connected in a sector gear 18, these sector gear 18 bridle joints are on another travelling gear 19, after a dividing plate 20 is passed in the axle center 191 that this gear 19 is connected, with square block 21 sockets, when sector gear 18 promotes via pole 161, when forming reciprocally swinging, can drive travelling gear 19 forward and reverse rotations, back and forth rotate thereby drive block 21.

One cylinder 22 that is arranged on headgear 2 inside is nested with on block 21, before this cylinder 22, the rear surface is respectively equipped with symmetric skewback 221,222, and central authorities articulate a sleeve 23 forwardly, this sleeve 23 passes retainer ring 24,25 and waterproof washer 26 after, stretch out at headgear 2 front ends, for the socket toothbrush, when motor 12 is started by switch 11 and controls its rotating speed, toothbrush can be just, reverse turn, and skewback 221 by cylinder 22,222 with the skewback of dividing plate 20 and the interaction of headgear 2 inner edge skewbacks 27, generation is advanced, the action that retreats is to reach the effect in thorough cleaning oral cavity.

See also Fig. 3 A and 3B, find out by knowing among the figure, gear 14,15 and the 18, the 19th is separately fixed at 17 of dividing plate 13,20 and bracing frames, make motor 12 when rotating, the square block 21 that is driven foremost produces forward and reverse reciprocal rotation, and rotate relative to driving sleeve 23, make toothbrush when level, reach the upper and lower moving effect of backwash that comes.

See also Fig. 4 A-4H, the action of swing sheet 16 of the present utility model is when bayonet lock 151 during in original position, swing sheet 16 be the level of state (as Fig. 4 A).When gear 15 is rotated in the forward, the upper stop piece of bayonet lock 151 pushing tows swing sheet 16 begins to swing (as Fig. 4 B) up, rotate to 90 when spending at gear 15, swing sheet 15 swings to peak (as Fig. 4 C), and when gear 15 continuation rotations, at this moment, the lower stop piece of bayonet lock 151 pushing tows swing sheet 16, make it gradually towards lower swing (as Fig. 4 D), when gear 15 Rotate 180s are spent, then swing sheet 16 horizontal (as Fig. 4 E), turn to 270 degree, then swing sheet 16 and put to minimum point (as Fig. 4 G) at gear 15, gear is rotated further, then bayonet lock 151 pushing tows are swung the upper stop piece of sheet 16, and make it begin to swing (as Fig. 4 H) up, can do reciprocal sustained oscillation by pushing tow swing sheet 16 by the lasting rotation of gear 15 by this.

And shown in Fig. 5 A and 5B, because the chamfered portion of cylinder 22 surperficial skewbacks 221,222 holds mutually with the skewback 201,27 of dividing plate 20, headgear 2, when the drive of cylinder 22 via square block 21, when producing forward and backward, this cylinder 22 will make cylinder constitute forward and backward moving because of the mutual slip on the inclined-plane of skewback 221,222 and 20127, relatively, make the toothbrush that is socketed on sleeve 23 when rotating, it is moving to reach the brush that advances, retreats, to increase the effect in cleaning oral cavity.

In sum, this utility model can rotate up and down electric toothbrush and forward and backward moving by the combination of gear train and oscillating deck simultaneously, reaches the effect in thorough cleaning oral cavity, and assembles simple and easy quick.
