Description

Hand-rotating toothbrush

Technical field

The utility model belongs to a kind of common living-hygienic articles, specifically a kind of hand-rotating toothbrush.

Background technique

Toothbrush is the necessity in daily life, and known toothbrush configurations are made of the brush head with bristle and brush handle, is used When, brush handle is held, bristle is attached to tooth and is rubbed back and forth.Tooth is cleaned with bristle along teeth space and is referred to as " erect brush ", is correct Method for brushing teeth；It vertically or intersects at teeth space bristle cleaning tooth referred to as " horizontal ", is incorrect method for brushing teeth.With The susceptible wrist fatigue of majority of brushing teeth of " erect brush " method feels inconvenient, therefore, causes the people of significant proportion still to use " horizontal Brush " method brush, brushes teeth even with erect brush method, because brush head is fixed on brush handle, people in order to thoroughly clean in tooth outside, The positions such as cusp, teeth space must convert various gestures during brushing teeth, and user is allowed to feel cumbersome, and these are all toothbrush knots Caused by defect present on structure.

Summary of the invention

In order to overcome the inconvenient for use of existing toothbrush, for the defect on existing Tooth-brush structure, the utility model provides one Kind hand-rotating toothbrush, the hand-rotating toothbrush eliminate the defect on existing Tooth-brush structure, simple and direct can accomplish " erect brush ", and It is easy to use, significantly beneficial to user.

Technical solution

The technical scheme adopted by the utility model to solve the technical problem is as follows: it is in cylinder that bristle combines on the head Shape is connect by coupling spindle with output gear in brush body.The gear of different-diameter meshes together, and it is big to constitute a transmission ratio In 1 gear unit, 1,2 or multiple such gear units are set in brush body, obtain higher transmission ratio, and lead to Cross output gear output.To keep the output of brush body internal gear consistent with head toothbrushes direction of rotation, conical tooth is set in brush body For wheel for adjusting direction of rotation, above gear unit and angular wheel collectively form gear set.Gear set is housed in Handle axis Input gear and torsion spring, torsion spring one end is connected in Handle axis, and the other end is fixed on brush body, outside brush body If handle and closely linked with brush body inner handle shaft, handle has initial position under the action of torsion spring.It is practical using this When novel, hand-holding toothbrush body, finger presses handle, and handle initial bit changes, Handle axis rotation, and Handle axis, which drives, is mounted in Handle axis On input gear rotation while also make the torsion spring compression in the Handle axis, the rotation driven gear group of input gear Rotation drives coupling spindle rotation, finger pine eventually by output gear after gear set amplifies revolving speed and changes direction of rotation It opens, handle resets under the action of torsion spring, and gear set is driven to rotate backward, and coupling spindle reversely rotates.Finger presses repeatedly It unclamps, the change and reset alternating movement of handle initial bit drive coupling spindle to rotate back and forth, coupling spindle drives brush head and bristle Convolution turns, to realize the purpose brushed teeth.

Beneficial effect

The utility model has the beneficial effects that finger presses handle, head toothbrushes drive bristle to rotate back and forth along teeth space direction, Real " erect brush " is realized, and teeth space, massage gum can be cleared up well, cleaning effect is more excellent.And easy to use, It is structurally reasonable.
