The specific embodiment
The utility model will be further described below in conjunction with accompanying drawing and embodiment shown in the drawings.
As depicted in figs. 1 and 2, electric toothbrush of the present utility model comprises: place the motor 1 of toothbrush body 9 inner chambers and the cylindrical eccentric 2 on motor 1 power output shaft, this eccentric 2 is provided with eccentric orfice 2a, handle 8 with the 9 top active buckles of toothbrush body, the end of this handle 8 and rotary toothbrush head 7 flexibly connect, between eccentric 2 and rotary toothbrush head 7, be provided with the driving lever assembly of transferring power, stage casing socket one water proof ring 4 of this driving lever assembly, water proof ring 4 are fixed on the seam of toothbrush body 9 and handle 8.Described motor 1 drives described eccentric 2 and rotates, and it be that fulcrum swings with water proof ring 4 that the end that eccentric 2 is stirred the driving lever assembly makes the driving lever assembly, other end promotion rotational head 7 forward and reverse reciprocal rotations of driving lever assembly.
Fig. 2 is the structural representation of this electric toothbrush critical piece handle 8, rotary toothbrush head 7, eccentric 2 and the driving lever 5 of forming the driving lever assembly and commutation piece 3.The head of described handle 8 is provided with the locating hole 8b that connects rotational head 7, tail end is provided with the location buckle 8a that cooperates with toothbrush body 9 tops, handle 8 is inserted the cooperation position of toothbrush body 9 along the axle center, the buckle 8a of handle 8 tail ends is stuck on the toothbrush body 9 after putting in place, and handle 8 is fixed on the toothbrush body 9.Described driving lever assembly comprises driving lever 5, commutation piece 3, the axis of guide 6, water proof ring 4, driving lever 5 has bulb front end 5a, this bulb front end 5a drops in the rotary toothbrush head 7 backside openings chute 7b backward, as shown in Figure 3, the rear end of driving lever 5 is plugged in the jack 3b of commutation piece 3 leading sections after passing the centre bore 4a of water proof ring 4.Described commutation piece 3 also is provided with direction and toothbrush body 9 vertical axis hole 3c, and the axis of guide 6 passes the axis hole 3c of commutation piece 3 and the through hole 13a on the toothbrush body support 13, and its two ends are fixed on toothbrush body 9 both sides, and commutation piece 3 can be free to slide along this axis of guide 6.Described eccentric stiffener is the eccentric 2 that has an eccentric orfice 2a, it can certainly be the eccentric of the eccentric protruding axle of band, it can also be the change-speed gearing group of band eccentric shaft, take first kind of mode in this utility model, this eccentric 2 drops among the vertical groove 3a of commutation piece 3 rearward end, makes the power from motor 1 be passed to commutation piece 3.Like this, by the commutation piece 3 and the axis of guide 6 thereof, it is the positive and negative reciprocal horizontal hunting of fulcrum with water proof ring 4 that the rotatablely moving of eccentric 2 is converted into driving lever 5, makes the 7 positive and negative reciprocal rotations of rotary toothbrush head thereby the bulb front end 5a that drives driving lever 5 stirs the chute 7b of rotary toothbrush head 7.
As Fig. 2 or shown in Figure 3, except leading section is installed single rotary toothbrush head 7, can also on planting, rearward end form fixed manual toothbrush head by bristle 8c on the handle 8.
Be a cavity in the jack 3b of described commutation piece 3 leading sections, driving lever 5 rearward end can jack 3b be that freely rotate in this cavity in the axle center, this structure makes toothbrush body 9 to do into a bent shape in jack 3b position, and toothbrush can more effectively go deep into the oral cavity like this, the cleaning molar.
For guaranteeing the swing of driving lever assembly steadily, described water proof ring 4 has appropriate elasticity.The diameter of water proof ring 4 centre bore 4a is slightly littler than the diameter of driving lever 5, and the centre bore 4a of water proof ring 4 is strutted and tightly be enclosed within driving lever 5 middle sections by driving lever 5, and water proof ring 4 had both played waterproof action, the fulcrum when moving as brush driving lever assembly again simultaneously.
As shown in Figures 2 and 3, described rotary toothbrush head 7 back sides are provided with shaft hole 7a and the annular on-slip groove 7C that falls, one steel axle 10 passes its upper end, damping spring 11 backs and is fixed in the fixing hole 8b of handle 8, its lower end is plugged in the shaft hole 7a at rotary toothbrush head 7 back sides, after the bayonet lock through hole 8d that one bayonet lock 12 passes handle 8 sidewalls pegs graft and to put in place, the on-slip that its end falls into rotational head 7 falls in the groove 7c, rotational head 7 is suspended on the handle 8, and can do the rotation of both forward and reverse directions around steel axle 10, realized that thus the rotary toothbrush head is connected with the rotary moveable of handle.
Fixedlying connected between the fixing hole 8b of above-mentioned steel axle 10 and handle can be adopted following dual mode:
Be connected for tight fit between first kind, steel axle 10 and the fixing hole 8b;
Second kind, on the sidewall of fixing hole 8b, open a through hole, pass the steel axle 10 that this through hole will be plugged in the fixing hole 8b with a bayonet lock and compress.
By above-mentioned structure as can be known, only need withdraw from bayonet lock 12 when changing the rotary toothbrush head, change new brush, load onto bayonet lock 12 again and get final product, very convenient.
Fig. 4 is the direction of motion sketch map of head toothbrushes.When eccentric 2 was in the middle position, (Fig. 4 a) for the rotational head 7 of naming a person for a particular job is pushed into middle position with water proof ring 4 for the bulb front end 5a of driving lever 5; When eccentric 2 rotated to location right, driving lever 5 was the fulcrum counter-clockwise swing with water proof ring 4, and eccentric 2 is swung (Fig. 4 b) clockwise by driving lever components drive rotational head 7; When eccentric 2 rotated to the position on the left side, driving lever 5 was that fulcrum is swung clockwise with water proof ring 4, and eccentric 2 is by driving lever components drive rotational head 7 counter-clockwise swings (Fig. 4 c).Therefore, described motor 1 drives described eccentric 2 and constantly rotates, it is the forward and reverse swing of fulcrum with water proof ring 4 that eccentric 2 will constantly promote driving lever 5, and the bulb front end 5a on the driving lever 5 promotes rotational head 7 again and back and forth rotates in certain angle, and its movement locus is one section circular arc line.
