Description

Toothbrush
Technical field
The present invention relates to toothbrush.
Background technology
Manual and electric toothbrush all has shank, and shank extends to head toothbrushes from handle, has the bristle that a row is used to brush teeth on the head toothbrushes.The various solid shapes and the structure of the overall toothbrush contact surface that is used to provide different have been well-known.People recognize for a long time, certain shape, and for example spill or convex are preferred for certain purposes and are respectively applied for the outer surface of brush front tooth and the inner surface of front tooth.Compromise design arrangement comprises the complicated overall bristle surface or the shape (spill or convex) of mixing, and they can be formed on the single head toothbrushes.Adopted the Flexible toothbrush head recently, it can change usually, thereby the bristle configurations of different expectation is provided.In these cases, head toothbrushes be by can keeping difform flexibility or deformable material to make, so that the shape that is transformed into expectation in manual operation each time is so that after using, to present the bristles of spill for example or convex.This needs the user to hold head toothbrushes, if bristles is moist or scribble toothpaste this is inconvenient, and under any circumstance this usually all is antihygienic.
Summary of the invention
The objective of the invention is to overcome the problems referred to above or alleviate the problems referred to above at least.
The invention provides a kind of toothbrush, it comprises the long handle portion with longitudinal axis; And the long teeth brush of making by flexible material, it has row's bristles along what described longitudinal axis was connected to shank end to end than distal portion and on a main surface of head toothbrushes.The push rod that extends along shank be connected to head toothbrushes than on the distal portion.Control lever is installed on the toothbrush, generally is used for along described longitudinal axis mobile putter, changes between spill and convex with effective length that changes head toothbrushes and the shape that changes the main surface of head toothbrushes.Head toothbrushes is formed with the slit of horizontal expansion in described main surface, with convenient head toothbrushes is bent to spill and convex.
Control lever can be pivotally mounted on the toothbrush and be formed with arcuate surfaces, and arcuate surfaces is mechanically connected on the end of push rod, and longitudinally axle is mobile for push rod when rotating with convenient control lever.
Arcuate surfaces is preferably formed with step, and described step is determined the incremental motion of push rod when control lever rotates.
Control lever can be installed in the inside of toothbrush and extend the outer surface of toothbrush, so that the part that exposes of control lever can be operated easily by thumb, thus the shape of regulating head toothbrushes.
Description of drawings
Pass through case description toothbrush of the present invention below in conjunction with accompanying drawing, wherein:
Fig. 1 is the sectional view that is in the toothbrush under a kind of shape;
Fig. 2 is the sectional view that is in the toothbrush under the another kind of shape; And
Fig. 3 is the sectional view that is in the toothbrush under another shape.
The specific embodiment
Please refer to accompanying drawing, toothbrush 10 has long handle portion 11 and long Flexible toothbrush head 12.One row's bristles 13 is installed on the main surface 14 of head toothbrushes 12.Straight push rod 15 extends along the inside of shank 11 and is connected on the far-end 16 of head toothbrushes 12.Control lever 17 is from the inside of overlapping or adjustment part (housing) 18 extends and be installed in rotation on toothbrush 10.Cover 18 has arc groove 19, and groove 19 is formed with step shape surface, and the hooked end 20 of straight push rod 15 is supported on the step shape surface.
The slit 21 that surface 14 is formed with horizontal expansion (as Fig. 3 the most clearly shown in), slit 21 makes head toothbrushes can more easily adopt spill shown in Figure 1.Therefore the end of control lever 17 exposes the outer surface of toothbrush 10 and can be operated (push away or draw) by user's thumb easily.
In the use, control lever 17 is used to change the shape of head toothbrushes, and is used for being placed in the step of groove 19 one by hooked end 20 card and goes up and keeps the shape selected.Head toothbrushes 12 can change shape, so that surface 14 can be changed between the convex shown in Figure 3 in spill shown in Figure 1.This is because the lengthwise movement of the operation of control lever 17 and push rod 15 has changed the effective length of the head toothbrushes of general setting, less relatively is preferred for fully cleaning interdental gap in shape employed in figure 1 when regional when the end of bristles concentrates on.Shape among Fig. 2 is generally used for cleaning the outer surface of tooth, and the shape of Fig. 3 is generally used for brushing up and down.Under any circumstance, and during each or single tooth are scrubbed action, need or when expecting different shape, as mentioned above, regulate simply and keep different selected shapes that suitable convenience is provided.The variation of shape can realize that hand is normally being held toothbrush by enough hands, and needn't contact the shape that head toothbrushes or bristles change head toothbrushes.
