CN2445631Y - Two-group offset triangle shape brushing swing toothbrush - Google Patents

Abstract

The utility model relates to a two-group offset triangle-shaped brushing swing toothbrush. A handle 13 is held, and toothpaste is extruded on brush bristles. A toothed rack end 16 (the matching of elastic material 12 is random and is stressed to be deformed) is applied best acting force by a palm and fingers. The elastic force and various resistance forces of a brush handle 5, brush bristle basal seats 3 and 4, sealing elastic material 11 and internal return spring are overcome. In this way, two groups of brush bristles 1 and 2 are reciprocally swung, and the toothpaste is uniformly distributed on the brush bristles. The two groups of brush bristles are opened at (45 DEG or about 135 DEG) angle and are put on two side faces of teeth (gums). Like the actions, the pointed end parts of the two groups of star-shaped brush bristles produce rotary extrusion force along both sides of tooth gap, dirt can be removed. At the same time, a tooth occlusal surface can be opened by horizontally moving the handle, a pinch of brush bristles are combined, and the dirt on the tooth occlusal surface can be brushed in the mode of pulling a saw.

Description

Two groups of eccentric triangle bristle swing toothbrush

The utility model relates to and belongs to daily living article---and toothbrush, operation be cleaning simultaneously once, in the tooth, the dirt of outer two sides and two tooth junction teeth spaces and ditch nest.

The traditional toothbrush of people's use now is by some pinches of garden shape bristle pack, plants and is connected on a bristle pedestal, once can only clean a facing, and bristle is difficult for cleaning to the dirt of teeth space depths ditch nest." the clean spy of tooth " patent No. 96314449, though there are three bristle pedestals once can surround three faces of tooth, but the corresponding both sides bristle that claims, in the tooth of brushing teeth, during outer two faces, bristle can not rotate, and two faces of tooth are not had extruding force, so bristle can not be brushed teeth along the both sides teeth space, do not meet the correct principle of brushing teeth.

The utility model purpose is to realize like this.The triangle bristle pack of forming by some bristles, plant on the bristle pedestal that is connected on two symmetries, bristle limit, both sides is enclosed in two faces of tooth, the edge rotates on facing along teeth space, under the elastic force effect of the elastomeric material relevant with bristle, automatically adjust the extruding force of bristle to tooth, bristle can be deep into any corner of tooth, especially can effectively brush the dirt of junction between two teeth.

Such scheme is: by the rack drives gear mechanism, make two groups of bristles being installed in respectively on the two elasticity brush holders (some pinches of " " bristle pack being made up of some bristles) reciprocally swinging.

Figure 20 is that spur rack 10 drives Jie's gears 9, drives arm gear 8 energetically and rotates the theory structure schematic diagram round about with power transmission shaft 20 on two diameter of axle gears 7 that mesh.

Among the figure: 1. soft bristle 2. hard bristle 3. bristle pedestals 4. brush holder pedestals, 5. brush holders (outward appearance is bung flange shape brush holder) 6. finer wire 7. diameter of axle gears (1/8～3/8 radian length) 8. energetically arm gear (1/8～3/8 radian length) 9. the sealing of Jie's gear 10. tooth bars 11. play the two-sided tooth bar driven wheel 20. brush holder output shafts of flexible material 12. rigid elastomeric material 13. handles 14. casings, 15. springs, 16. tooth bar promote-sides, 17. two-sided tooth bar 18.19..

In Fig. 1, handle (13) is connected with casing (14) by rigid elastomeric material (12) (as elastic caoutchouc, plastics, spring, elastic steel sheet etc.), or handle (13) is directly selected hard elastic material for use.Power input tooth bar promote-side (16) is connected in the termination of tooth bar, between this termination and casing (14), is tightly connected with not only soft but also thin organic elastic material 11 (as elastic caoutchouc), and tooth bar is exposed the outer movable part sealing of casing.When tooth bar is moved, be subjected to this elastic resistance minimum in casing, water can not be flow in the driving mechanism from the movable part office of tooth bar and casing.After tooth bar promote-side (16) are subjected to motive force, drive tooth bar (10), overcome spring (15) and elastomeric material (11) elastic force and some resistances, drive Jie's gear (9), make and amplify arm of force gear (8) (abbreviation gear wheel 8, the diameter of this gear is bigger than the diameter of coaxial driven gear (7), drive gear wheel (8) and drive coaxial driven gear (7) rotation with the turning moment that increases brush holder (5), gear wheel (8) and gear (7) concentric with the concentric brush holder output shaft (20) that fuses of axle brush holder (5), gear (7) on the two brush holder output shafts is meshed, gear (7), (8) gear radian is at 1/8th to 3/8ths radian lengths.When tooth bar (10), stressed back rotates two brush holders (5) by gear drive to the inside, recover under the effect of elastic force at spring 15, two brush holders 5 are rotated laterally make two bristle pedestals (3), (4) go up bristle (1), (2) thus, back and forth rotation, be angle reciprocal rotary oscillation in 45 °-135 ° scope of the bristle and the face of brushing teeth, the angle of two groups of bristle encirclement teeth is about 90 ° when static, and promptly the angle of bristle and facing is about 45 °.Fig. 2, Fig. 3, Fig. 7, bristle pedestal (3) (4) are eccentric in brush holder (5) and connect, and brush holder (5) is to make with elastomeric material, and axial outer end is a shape or a circle round in the shape of a spiral, is called for short " spiral shell-circle " shape.This diameter of axle is made hollow interior and is penetrated finer wire 6, to increase brush holder (5) rebound velocity and mechanical strength.Termination at brush holder (5) is provided with a wedge shape spline neck platform shape with the junction of importing 7 of gears, is convenient to change the bristle on the bristle pedestal on the brush holder (5).From Fig. 2, Fig. 3, Fig. 3-1, Fig. 3-2, Figure 12, as can be seen, be eccentric in the bristle pack (1) that brush holder 5 connects, (2) (being called for short " " bristle), lined up fur at the bristle of the periphery of " " bristle, constitutes complete " △ " bristle pack, " △ " bristle pack is connected independently and is connected with elastomeric bristles pedestal (3) on the elastomeric bristles pedestal (4) again, or " △ " bristle is directly planted on the elastomeric bristles pedestal (3).The most advanced and sophisticated place of the triangle of " △ " bristle tilt towards the direction of brush holder or with the vertical direction of brush holder lower end.Two-sided tooth bar (17) driven wheel (18), (19) make two brush holders (5) reciprocally swinging simultaneously, and other is identical with above-mentioned described single-side rack operation principle.

Using method of the present utility model is achieved like this, earlier toothpaste is squeezed on any a group of two groups of bristles, hold handle 13, food, thumb is to the drive end of tooth bar 16, overcome the elastic force of spring 15 and sealed elastomer 11 and all resistances of gear driven mechanism, two " △ " bristle pack is rotated to the inside.Unclamp active force, under the effect of the restoring force of spring 15, make the rotation round about again of two bristle pack tooth bar end 16.Two bristle pack are placed on the both sides of tooth, the action of repetition aforesaid operations, two " △ " bristle pack is from the triangled tip hair end of bristle, limit extruding massage gum (bristle is in tooth and the vibration of gum junction), the limit is done along the two sides of tooth, clears up the dirt of two facings, and two groups of bristles close up, be one group of intensive bristle, brush teeth with the Dragsaw type method just and sting the dirt of jaw face.
