Abstract

The utility model discloses a toothbrush, aimed at providing a multifunctional toothbrush which can coordinate the transverse movement and the vertical movement of the toothbrush and form any angle, and can wipe off the foreign body by the incidental toothpick. The utility model comprises a toothbrush handle (1), a toothbrush head (2), a toothpick (11), a pin (14) and a plurality of toothbrush bristle (16), wherein, the toothbrush head (2) comprises a counter bore type lumen (4), a canulate mandrel (8), a convex tip (9), an external tooth (10) and a small via hole (15), while the toothbrush handle comprises a columniform convex table (3), a via hole (5), an inner tooth (6), a counter bore (7) and a ladder type counter bore (13). The utility model can be widely used in daily life.

Description

A kind of toothbrush

Technical field

The utility model relates to a kind of toothbrush.

Background technology

Though be widely used in actual life, also there are some problems in known toothbrush really, as otherwise be that head toothbrushes becomes in-line with toothbrush handles, only be fit to horizontal brush, or become the T font, only be fit to perpendicular brush, can not can not form arbitrarily angled simultaneously the two fine taking into account.

The utility model content

Technical problem to be solved in the utility model is to solve the deficiencies in the prior art, and a kind of toothbrush is provided, and the head toothbrushes of this toothbrush can rotate arbitrarily in the 360 degree scopes relative to toothbrush handles, and promptly horizontal brush and perpendicular brush can finely be taken into account, and can form arbitrarily angled simultaneously.

The technical scheme that the utility model adopted is: the utility model comprises toothbrush handles, head toothbrushes, some bristles, described bristle is fixed on the front of described head toothbrushes, the positive approximate vertical of the head of described toothbrush handles is provided with a cylinder boss that stretches out, approximate mid-section is provided with a counterbore inner chamber at described head toothbrushes back, and described cylinder boss and described counterbore inner chamber match to merge to form and be rotationally connected.

The utility model also includes pin, be provided with through hole with described cylinder boss concentric at the head of described toothbrush handles, one week of middle and upper part at described through hole is provided with some internal tooths of dividing equally, the outside circle of described internal tooth and described through hole are on the same face of cylinder, the back side that the root circle of described internal tooth connects described toothbrush handles forms counterbore, be provided with in the bottom of described counterbore inner chamber and its concentric and the hollow mandrel that protrudes upward, described hollow mandrel is made up of the protruding tip of certain interval mutually some, roughly the first half of the described protruding tip is provided with external tooth, the root circle of described external tooth and described protruding tip the latter half coexist on the face of cylinder, described protruding tip the latter half and described through hole coupling, described internal tooth and the interlock mutually of described external tooth coupling, be provided with its concentric in the bottom of described counterbore inner chamber and connect the small through hole of described head toothbrushes, the head of described pin passes the hollow part and the described small through hole interference fit of described hollow mandrel, and the afterbody of described pin just drops in the described counterbore with described counterbore coupling.

The utility model also includes toothpick, an end of described toothpick be provided with the shaft shoulder, the afterbody of described toothbrush handles is provided with the ladder counterbore, described toothpick is fixed in the described ladder counterbore by the described shaft shoulder and described ladder counterbore interference fit.

The beneficial effects of the utility model are: because head toothbrushes and toothbrush handles are rotationally connected, the head toothbrushes of toothbrush can rotate arbitrarily in the 360 degree scopes relative to toothbrush handles, be that horizontal brush and perpendicular brush can finely be taken into account, can form simultaneously arbitrarily angled, horizontal brush and perpendicular brush can finely be taken into account, while can form arbitrarily angled, and is particularly suitable for children's use; Owing to be provided with toothpick at the toothbrush handles tail end, when the teeth space card had the foreign matter brush not get off, available toothpick was in time foreign bodies removal again; Simultaneously, when finding that the bristle root has foreign matter, can remove it with toothpick.

The specific embodiment

As Fig. 1; Fig. 2; Fig. 3; Fig. 4; Fig. 5; Fig. 6; shown in Figure 7; profile of the present utility model and existing toothbrush are unanimous on the whole; the utility model comprises toothbrush handles 1; head toothbrushes 2; pin 14; some bristles 16; bristle 16 is fixed on the front of head toothbrushes 2; itself plane, place of the horizontal approximate vertical of the head of toothbrush handles 1 is provided with a cylinder boss that stretches out 3; head toothbrushes 2 is provided with a counterbore inner chamber 4 in the back approximate mid-section; cylinder boss 3 matches to merge to form with described counterbore inner chamber 4 and is rotationally connected; the head of toothbrush handles 1 is provided with the through hole 5 concentric with cylinder boss 3; in that roughly one week of middle and upper part of through hole 5 is provided with some internal tooths 6 of dividing equally; the outside circle of internal tooth 6 promptly with described through hole 5 on the same face of cylinder; the root circle of internal tooth 6 connects the other end and forms counterbore 7; in counterbore inner chamber 4, be provided with the hollow mandrel 8 that stretches out with one heart from its bottom; hollow mandrel 8 is made up of the protruding tip 9 of certain interval mutually some; roughly the first half of the protruding tip 9 is provided with external tooth 10; the root circle of external tooth 10 and the protruding tip 9 the latter halfs coexist on the face of cylinder; the protruding tip 9 the latter halfs and through hole 5 couplings; internal tooth 6 and external tooth 10 coupling interlocks mutually; be provided with concentric and connect the small through hole 15 of head toothbrushes with it in the bottom of counterbore inner chamber 4; the head of pin 14 passes the hollow part and described small through hole 15 interference fit of hollow mandrel 8; the afterbody of pin 14 just drops in the counterbore 7 with counterbore 7 couplings; protection connecting portion sanitation and hygiene; when wanting rotary tooth brush head 2; as long as bite head toothbrushes 2 gently with tooth; with certain force rotary tooth brush handle 1; toothbrush handles 1 is passed to moment at internal tooth 6 places of connecting portion; the power that produces a twisting imposes on the protruding tip 9; the strain that the protruding tip 9 is produced to the heart direction; so the protruding tip 9 separates with internal tooth 6; make head toothbrushes 2 after toothbrush handles 1 is rotated a direction; after the cancellation rotatory force; the protruding tip 9 under the elastic-restoring force effect, recover normal shape again and with internal tooth 6 interlock mutually, prevent arbitrarily relatively rotating of head toothbrushes 2 and toothbrush handles 1.

On the basis of above-mentioned embodiment, afterbody in toothbrush handles 1 is provided with toothpick 11, one end of toothpick 11 be provided with the shaft shoulder 12, the afterbody of toothbrush handles 1 is provided with ladder counterbore 13, toothpick 11 is fixed in by the shaft shoulder 12 and ladder counterbore 13 interference fit in the ladder counterbore of afterbody of toothbrush handles.

Described toothbrush handles 1, head toothbrushes 2, toothpick 11, pin 14 are single injection-molded, and raw material is PP; Described bristle 16 is made for nylon.
