Abstract

The invention discloses a toothbrush with bristles doing one-dimensional, two-dimensional and three-dimensional omnidirectional motion. A driving mechanism drives a flexible shaft to collide with the inner wall of a brush neck, so that the rotation motion of an eccentric shaft is changed into rotation and reciprocal linear motion (by overcoming the elasticity of a spring); when the eccentric shaft from the end head to a smooth convex curve close to a root on the inner side strikes the inner wall of a substrate, irregular displacement such as radioactive ray displacement is generated relative to a hole center, and the bristles on the substrate do one-dimensional, two-dimensional and three-dimensional omnidirectional motion; and a tact switch is arranged on an intersection of the brush neck and a handle so as to avoid malfunction in operation.

Description

Bristle one, two dimension; The toothbrush of three-dimensional all-directional moving

The present invention relates to a kind of bristle one, two dimension; The toothbrush of three-dimensional all-directional moving makes bristle can select one according to the pedestal pass. two dimension; The motion .. of three-dimensional all-directional

The present electric toothbrush patent No.: 200420066186,2 200520110003,7 just rely on pedestal and the articulation of brush neck to be wrapped in elastomeric elastic force, make the eccentric shaft resilience force that in the pedestal hole, moves reciprocatingly little, life-span is short. the axial plane of pedestal endoporus eccentric shaft contacts with the hole inwall, and frictional force strengthens between the two. if three-dimensional driving device change into rotary oscillation mechanism then bristle can only do two dimensional motion. directly brush switch outside neck and the handle and the user felt under the weather should produce misoperation.

The present invention overcomes above-mentioned a kind of bristle that makes of deficiency invention and does one dimension; Two dimension; Three-dimensional all-directional moving. and it is easy to use for the engineering principle to meet the people.

The present invention seeks to realize like this. at arc-shaped bend elasticity brush neck is to connect eccentric shaft and flange shaft respectively in the termination of elasticity flexible axle. drive flexible axle by two dimension or three-dimensional driving machine hook respectively, the smooth cam that makes it and brush neck rotary collision drive off-axis axle head head and end root overcomes spring force and does straight line and rotatablely move; Then bristle does one; Two dimension; Three-dimensional all-directional moving.

Fig. 1 is a main station of the present invention portion cut-away view.

Fig. 2 is the axis of symmetry cutaway view of front view of the present invention.

Fig. 3 is a brush neck assembly echelon sectional view.

Fig. 4 is the axis of symmetry three-dimensional cutaway view of Fig. 3.

Fig. 5 to Figure 19 is respectively the cutaway view of Fig. 2.

Among the figure: 1. bristle pedestal; 2. eccentric shaft; 3. brush neck left side part; 4. brush the right part of neck; 5. stage clip; 6. flexible axle; 7. flange shaft; 8. elastomer; 9. bristle; 10. driving gear shaft; 11. spin; 12. handle casing; 13. switch; 14. driving mechanism; 15. power supply; 16. driving gear.

Open switch 13 energized 15, driving gear 16. gear shaft 10 of then three-dimensional driving mechanism (or motor) 14 make flexible axle 6 eccentric shafts 2 that connect with axle 7 (its end link to each other with flexible axle other end axle 10 activity tight fits) do straight line and rotatablely move. and be that necks 3 are brushed in flexible axle (with the close coiled of finer wire) 6 collisions; A 4 smooth inner walls (brush neck left side, right part 3,4 junctions and pedestal 1 are by the elastomer parcel), become with respect to brush neck axle 2 vertical power by revolving force, when brush power imposes on a left side, between the two gap is crooked thereupon during right part 3.4, and pedestal 1 hole is long and wide to be equated or then brush neck axle 2 when unequal to drive pedestals 1 and do one dimension or two dimensional motion. and the hole depth of pedestal 1 and flexible axle 6 are being brushed neck 3; 4 inwall three-dimensional impact motion, eccentric shaft 2 drives the motion of pedestal 1 apteryx and distance depends on the distance that schedules pedestal 1 geometry and its axially-movable. and bristle 9 is done one dimension respectively thus; Two dimension; Three-dimensional all-directional moving, and under stage clip 5 elastic force effects, make pedestal 1 reciprocating along brush neck axle 2. brush neck axle 2 is provided with slick protruding inclined to one side arc spherical surface body (being equivalent to eccentric cam) at head or to 2 of roots (inboard partially); Changed the patent No.: 200420066186.2; 200520110003.7 the axial plane of eccentric shaft and pedestal hole face contact area are big; The frictional force that reduces each other improves mechanical efficiency. when axle 2 imposes on pedestal 1 vertical power when excessive; Then the alveole of axle 10 terminations of axle 7 connection one makes and supports spin 11 rollings; Its spin in the alveole of the other end and support handle shell 12 produces rolling friction thus and reduces resistance. when brush power is transmitted to brush neck 3; 4 their horizontal wall thickness are then brushed neck consistent with the manual toothbrush bending direction (sample) greater than vertical wall thickness. and touch-switch 13 is located at brush neck and handle junction; Big slightly generation malfunction is done in order to avoid handle is exerted oneself. and the elastomer 8 of brush neck assembly tail end is tightly connected with handle assembly.
