Abstract

The utility model relates to an electric tooth brush with bristle capable of deeply brushing tooth gap and massaging gum. The base of each bristle is plugged with a moveable block which can adjust the bore direction of a long bore and make the front end of a drive rod form an irregular crank segment. The crank segment of the drive rod can be inserted into the long bore of the moveable block, which can make each bristle body do cleaning action on the different positions on the bristle base, wherein, when the long bore is in lateral direction, straight direction or alternative arrangement, the bristle body can do the actions of moving forward and backward and swaying left and right or both actions to obtain the efficiencies of deeply brushing tooth, cleaning tooth surface and massaging gum.

Description

Bristle can go deep into the electric toothbrush of teeth space and massage gingiva

This utility model is the electric toothbrush that a kind of bristle can go deep into teeth space and massage gingiva, relates in particular to the drive link that a kind of usefulness is crank design and drives body brush, makes carrying out front and back in its what hair brush base or waving or the toothbrush of both duplex campaign.

Press, one of common as electric toothbrush mainly be to drive bristle in two ways to come cleaning teeth and teeth space, one is to be to make the rotating shaft of motor transmission bristle, makes the bristle rotation, user only needs that hands is flat to be held, bristle just can clean teeth space; Second it be that bristle is divided into several body, and each group bristle borrows drive screw to drive, but scrubs about doing on the what flank of tooth; So, no matter bristle is scrubbed in which way, all only pay attention to the cleaning of the flank of tooth, but can't go deep in the teeth space and ignored massage, the maintenance of gingiva, can make bristle go deep into teeth space and massage gingiva on the user application of force of the still needing what toothbrush, and bristle is also only done the dullness motion of same way as, can't effectively remove the interior residue of teeth space, and the regret of blemish in an otherwise perfect thing when using is quite arranged.

The purpose of this utility model is to provide a kind of the order to do the action advancing, retreat in the body brush what hair brush base to go deep into teeth space, or do the action that teeters, or do compound action in conjunction with dual mode so that have the electric toothbrush of effects such as going deep into teeth space, massage gingiva and the cleaning flank of tooth concurrently with the cleaning flank of tooth.

Cause above-mentioned purpose for reaching, the bristle that this utility model is carried can go deep into the electric toothbrush of teeth space and massage gingiva, comprise a lever, a drive link, a cover body and some body brush, wherein, the drive link front end is the crank design of not planning, and the hair brush base of cover body front end matches with the base of body brush, the base center of hair brush base is provided with perforation, around the perforation and ring establish depression, for movable block wherein with the protruding grain clip around it, the heart and be provided with slotted hole among the movable block; Drive link penetrates in the slotted hole of sliding seat one by one, borrows the drive of lever internal motor, can make body brush do the start of advancing, retreating or wave genetic system in the bristle of cover body, and the flowing mode of doing of body brush is then looked on the sliding seat direction of slotted hole and controlled it.

This utility model novel structure, safe in utilization comfortable, have thorough cleaning teeth, the effect of massage gingiva.

Below in conjunction with graphic and embodiment this utility model is elaborated:

Fig. 7 is that this utility model is implemented illustration

See also Fig. 1, this utility model comprises a lever 1, a drive link 2, a cover body 3, and some body brush 4, wherein:

Lever 1 front end is a hollow convex column 11, the protruding grain 111 of molding one clip on the projection 11; Drive link 2 is a body of rod, and the front end punching press forms the crank section 21 of not planning shape, and each tune angle of crank section 21 is neither identical; Cover body 3 is a hollow cylinder, can cover on the what lever 1, and the bottom lower is established a clip hole 31, and cover body 3 front ends are a hair brush base 32, and hair brush base 32 root edges are arc modeling, and inside also forms some dividing plates 321; The base 41 of body brush 4 is implanted with bristle, a perforation 411 is established at base 41 centers, and ring is established depression 412 around the perforation 411, plugs a movable block 42 in the perforation 411, in the perforation 411 of movable block 42 with the protruding grain 421 clip what bases 41 of the location around it, the heart and be provided with slotted hole 422 among the movable block 42.

During combination, as shown in Figure 2, earlier each movable block 42 is tightly plugged in the perforation 411 of body brush 4 bases 41 one by one, borrow in location protruding grain 421 clip whats perforation 411 depression 412 on every side of movable block 42, again each body brush 4 is inserted in the hair brush base 32 of cover body 3 one by one, borrowing dividing plate 321 that body brush 4 is done one separates and the location, inferiorly stretch into cover body 3 and penetrate in the slotted hole 422 of movable block 42 with 21 of drive link 2 front ends, cover body 3 then is covered with outside the what lever 1 front end projection 11, borrow engaging and combination of the protruding grain 111 of clip and clip hole 31, and make drive link 2 must be subjected to the drive of lever 1 internal motor.

The making flowing mode and then can rely and adjust movable block 42 of body brush 4 to determine it, with consulting Fig. 2, when being laterally, the slotted hole 422 relative what hair brush bases 32 of movable block 42 put, and drive link 2 is when beginning to rotate, then body brush 4 can be done the start of advancing, retreating in hair brush base 32, as shown in Figure 3, at this moment, body brush 4 can go deep into teeth space to remove the residue in the teeth space; Again, the slotted hole 422 relative what hair brush bases 32 when movable block 42 are as shown in Figure 4 directly when putting,, then body brush 4 can be done left and right start of waving in hair brush base 32, as shown in Figure 5, and at this moment, body brush 4 can be scrubbed the flank of tooth, makes its cleaning, and simultaneously the residue in the teeth space is taken out of.

This utility model is done the flowing mode except that above-mentioned two kinds.Still can do duplex, see also Fig. 6, even the slotted hole 422 of sliding seat 42 with directly to, laterally interlaced mode is inserted in the hair brush base 32, then body brush 4 not only can advance, retreat (platform second, four groups of body brush), also can vacillate now to the left, now to the right (as first and third, five group of body brush) simultaneously, in other words, except that going deep into the while flank of tooth capable of washing the teeth space; Moreover, each body brush 4 is more because of irregular crank section 21 designs of drive link 2 front ends, and make its position neither identical, the comparatively protrusion that has, have comparatively in contract, thus, the 4 pairs of gingivas of hair body that contract in more can utilizing comparatively give the massage, and that borrows causes " go deep into teeth space, massage gingiva and scrub the flank of tooth " three kinds of effects to reach.

The example that preamble is lifted is that the slotted hole 422 for movable block 42 can be directly to the design when horizontal, and this utility model can be done the design of oblique slotted hole 422 in addition, as shown in Figure 7, another embodiment for this utility model, when the depression around the perforation 411 of body brush 4 bases 41 412 and the protruding grain 421 in the location around the movable block 42 increase to eight by original four, then the slotted hole 422 on the movable block 42 can be oblique design in addition, and it is more diversified to make body brush 4 make flowing mode.

Thus, not only can effectively promote electric toothbrush cleaning and the effect of massaging, convenience when more helping what raising production, Producer can be made a large amount of specification product, utilize identical accessory to form the body brush of different kenels, in order to do making flowing mode, in addition with the bristle that obtains different types, straight forming directly to slotted hole, horizontal slotted hole or oblique slotted hole, makes its also tool effect same as described above on the base of body brush.
