The object of the present invention is achieved like this: a kind of rotating head device of electric toothbrush, described rotating head device is provided with the brush of band bristle, brush is provided with open slot on one side, this brush is rotatably installed on the housing of electric toothbrush head, one head by motor-driven swingle is made as eccentric rod, and this eccentric rod stretches in the open slot of brush and stirs brush.
The rotating head device of aforesaid electric toothbrush, described brush is rotatably installed on the housing by locating shaft and bearing fixing.
In the rotating head device of described electric toothbrush, described brush activity is rotatably installed on the housing, this brush bottom surface is fixedly connected with the location axle sleeve, and the side of location axle sleeve is provided with the card division, and a card is stuck on the card division of location axle sleeve and will locatees axle sleeve and be fixed in the housing.
Wherein, described brush bottom surface is fixedly connected with the location axle sleeve and is: the brush bottom surface is provided with the centre bore position, and it is fastening with the centre bore position of brush behind the axle sleeve that a locating shaft that has the dried mushrooms head penetrates the location.Further, the centre bore position of described locating shaft and brush is by screw threads for fastening or fixing.
The rotating head device of described electric toothbrush, described card and housing are for removably connecting.Wherein, described card is provided with pars convoluta, and this pars convoluta inlay card is in the groove of relative set on housing.Described housing is made as the face-piece and the drain pan of engaging up and down, and a press strip is pressed between face-piece and the drain pan after pushing down card.An outside end of described card is made as pulls out tail end.An inside end of described card is made as the insertion guide end that has chamfering.
Use the rotating head device of electric toothbrush provided by the invention, this rotating head device is from the acquisition power that rotatablely moves of motor, circumference can be converted to the circle swing of brush, moving back and forth of imitation manual brushes more meets the traditional habit of artificial use.
Use the rotating head device of electric toothbrush provided by the invention, its eccentric rod that relies on the setting of swingle head is stirred brush and is realized swing, and it is simple in structure, be easy to assembling.
Use the rotating head device of electric toothbrush provided by the invention, this brush can be changed, through calculating, only 1/5 of the need original device price gets final product, be equivalent to obtain a brand-new electric toothbrush, thus with market on more the electric toothbrush of changing brush head compare, have good economic benefits.And, owing to be provided with card article in this rotating head device, thereby this card article can not only be with the fixing brush of the rotary sleeve that is fastenedly connected with brush, and because this card article is to be detachably connected in the housing of electric toothbrush head, therefore, the structure of this rotating head device can also make brushhead replacement simple.

The specific embodiment
Shown in Fig. 1, Fig. 2 and Fig. 5 A, Fig. 5 B and Fig. 5 C, the rotating head device of electric toothbrush provided by the invention, this rotating head device is arranged on the head of electric toothbrush.This electric toothbrush is provided with housing 1, is provided with battery 101 in the housing 1, and battery 101 is given motor 102 power supplies and controlled by switch 103.The outfan of motor 102 rotates through reducing gear 104 driven rotary bars 6.
This rotating head device is provided with the brush 3 of band bristle 31, is used for stretching into and stir brush for swingle 6 Yi Bian brush 3 is provided with open slot 32, and swivel head is rotated.This brush 3 is rotatably installed on the housing 1 of electric toothbrush head, and the head of a swingle 6 that is driven by motor 102 is made as eccentric rod 61, and this eccentric rod 61 stretches in the open slot 32 of brush and stirs brush 3.
When swingle 6 rotated, the movement locus of the eccentric rod 61 of its head was a circumference, because eccentric rod 61 stretches in the open slot 32 of brush 3, its motion will be stirred brush.Again since brush for being rotatably installed in the housing, so stirring of 61 pairs of brushes 3 of eccentric rod makes brush along its center of rotation left-right rotation.When eccentric rod 61 forwarded most significant end and least significant end to, brush 3 forwarded the home position to, and when eccentric rod 61 forwarded high order end and low order end to, brush 3 also forwarded high order end and low order end to.Therefore, the motion of brush is for swinging.
Wherein, described brush 3 can be rotatably installed on the housing 1 by locating shaft and bearing fixing, and this is common structure, and is not shown.
Further, as shown in Figure 3, Figure 4, brush of the present invention is also movable to be rotatably installed on the housing, is convenient to more changing brush head like this.The bottom surface of this brush 3 is fixedly connected with location axle sleeve 5, and the side of location axle sleeve 5 is provided with card division 52 (as square groove, annular groove etc.), and a card 7 is stuck on the card division 52 of location axle sleeve 5 and will locatees axle sleeve 5 and be fixed in the housing 1, upwards beats when rotated to prevent brush.
Wherein, above-mentioned brush bottom surface is fixedly connected with the location axle sleeve: brush 3 bottom surfaces are provided with centre bore position 33, it is fastening with the centre bore position 33 of brush 3 that one locating shaft 4 that has dried mushrooms head 42 penetrates circular hole 51 backs of locating axle sleeve 5, make between brush and the locating shaft loosening so that locating shaft is followed rotation during the swivel head rotation.Described locating shaft 4 can perhaps change thread segment into elasticity card end and fix by the locating shaft thread segment 41 of locating shaft 4 and centre bore position 33 screw threads for fastening of brush 3, rotates thereby brush drives locating shaft.To locate axle sleeve 5 and be inserted in locating shaft 4, directly contact, influence its rotate effect with locating shaft 4 to avoid stainless steel substrates.
Further, described card 7 and housing 1 are for removably connecting.Described card 7 is provided with pars convoluta 73, and these pars convoluta 73 inlay cards are in the groove 113 of relative set on housing 1.
Wherein, the housing 1 of described electric toothbrush is made as the face-piece 12 and the drain pan 11 of engaging up and down.Wherein, face-piece 12 tops are provided with prosposition 121, are used to place brush 3, and the swingle on the face-piece 12 presses position 122 to be used to keep a grip on swingle; The small sircle hole 111 of drain pan 11 uses for pulling out card article 7, this drain pan big hole 112 is the center of rotation of brush, and drain pan screens 113 is used for cooperating with card 7, and inlay card is lived the pars convoluta 73 of card 7, the pipe position 114 of drain pan is used to locate the straight position 74 of card article 7, and drain pan groove position 115 is used to place press strip 8.One press strip 8 is pressed between face-piece 12 and the drain pan 11 after pushing down card 7 and swingle 6.The tenon 81 of press strip 8 snaps in drain pan screens 113, and press strip bottom 82 is used to compress card 7, preferably is pressed in the straight position 74 of card 7, in order to avoid influence the function at card 7 other positions.
An outside end of this card 7 is made as pulls out tail end 71, is convenient to pull it by this tail end 71 when changing card article.An inside end of this card 7 is made as the insertion guide end 75 that has chamfering, when inserting, to play guide effect.The middle part of this card 7 is provided with circle position 72, and the card division 52 that this circle position 72 is used to be stuck in location axle sleeve 5 will locate axle sleeve 5 and be blocked, and prevent that it is upturned, and the while does not influence the rotation of locating axle sleeve 5 again.
According to above structure, rotating head device of the present invention, not only simple in structure, be easy to assembling, and changing brush head more easily, use more economical.
