Description

The reasonable toothbrush device of double end

The utility model relates to a kind of toothbrush.

The toothbrush that we use is now mainly brushed teeth by the motion of wrist and arm, Yun Dong strength and amplitude are bigger like this, and be subjected to the oral cavity to reach the limitation in interior cheek space, most of people can not take the upper and lower mode of brushing teeth that holds water but about pulling to and fro, make the part accumulation of tartar in teeth space, if things go on like this, can cause the generation of odontopathy, directly influence the normal function of tooth and attractive in appearance.

The purpose of this utility model is exactly in order to address the above problem, the reasonable toothbrush device of the double end that provides a kind of people of assurance correctly to brush teeth.

Technical solution of the present utility model:

The reasonable toothbrush device of a kind of double end, it is characterized in that it is mainly by head toothbrushes, the shift fork driving mechanism, turning round handle and housing forms, shift fork driving mechanism and turn round handle and be arranged in the housing, head toothbrushes (1) is two split brushes, they link to each other and pass housing (3) with separately handle (2) upper end turned round respectively, two turn round handle (2) on, the bottom all has an oblique arc-shaped slot (4), two outer rings, upper end of turning round handle (2) are equipped with little ball (5), the chute of they and housing (3) upper end inwall coincide and connects, two lower ends of turning round handle (2) the big ball (6) of all having spliced, the chute of they and housing (3) lower end inwall coincide and connects, the shift fork driving mechanism is by toggle (7), support (8), slide bar (9) and slip pin (10) constitute, support (8) upper end links to each other with toggle (7), toggle (7) is the ellipsoid of bobbin structure for the intermediate cross-section, the eel-like figure place of its bobbin structure connects with corresponding groove (11) activity of housing (3) upper surface, make the upper surface of toggle (7) expose the upper surface of housing (3), on the support (8), respectively be provided with a cylindrical slide bar (9) between four jiaos of the lower ends, four slide bars (9) correspondence respectively are positioned at two and turn round on the handle (2), in the oblique arc-shaped slot (4) of bottom, be connected with four slip pin (10) under four angles of support (8) lower end, chute (12) activity that they and housing (3) lower surface inwall correspondence position match connects.

The utility model adopts a pair of head toothbrushes (the addition width is equivalent to general toothbrush width) to do relative moving and rotating between last lower tooth, head toothbrushes is closed up accordingly, separately, interior poly-and flip-flop movement, interior when poly-, bristle is intensive strong, be convenient to the position that the part brushes difficult cleaning, when closing up, can work as general toothbrush uses, separately and during outer commentaries on classics, tooth boundary root dirt can be rejected and the tooth boundary is massaged, the motion amplitude of head toothbrushes is slightly larger than tooth length, can adjust by the width of cloth of opening in oral cavity during use, the cleaning of the tooth inboard that people are ignored easily is also very convenient, making brushes teeth becomes light rationally fast effectively, the guiding that can also correctly brush teeth to the user.

Fig. 1 is that structural representation cuts open in office of the present utility model;

Fig. 2 is the rearview that handle is turned round on the right side among Fig. 1;

Fig. 3 is the left view that handle is turned round on the right side among Fig. 1;

Fig. 4 is a shift fork driving mechanism schematic diagram of the present utility model.

As Fig. 1-4, the two split brushes and two of the utility model head toothbrushes (1) are turned round being connected should be and removably connecting of handle (2) upper end, so that change, the length of head toothbrushes (1) and width can carry out supporting according to child's adult different needs, the bristle of the comparable general toothbrush of bristle is short, the centre should be selected hard bristle for use, so that the softer bristle in both sides is worked the effect of offering an excuse and stalling off.Internal mechanical member applied metal of the present utility model is made processing.The width that the utility model is turned round the last oblique arc-shaped slot (4) of handle (2) should match with the diameter of slide bar (9) in the shift fork driving mechanism.

When the utility model uses, (the right side part of Fig. 1 middle shell is not drawn to grasp housing (3), it is identical with its left side), make the bristle of head toothbrushes (1) aim at the tooth that to clean with water, up and down back and forth promote toggle (7) in shift fork driving mechanism with thumb this moment, then toggle (7) drives its slide bar (9) and moves up and down along the two oblique arc-shaped slots (4) of turning round handle (2), owing to be subjected to the effect of oblique arc-shaped slot (4) trend, make toggle (7) when upwards promoting, two turn round outer mobile and outer rotation that handle (2) is made relative direction, the two split brushes of their upper ends are flipped an angle (generally below 60 degree), thereby automatically the dirt in the teeth crevice is cleaned with water, and when toggle (7) when promoting downwards, two turn round handle (2) do relative direction in move and interior rotation, the two split brushes of their upper ends are closed up again, and move operation in the oral cavity is promptly finished the process of brushing teeth so repeatedly.
