Description

Can changing brush head and the toothbrush that can become brush head angle

Technical field

The utility model belongs to a kind of energy changing brush head and can become the toothbrush of brush head angle.

Background technology

The patent No. is the technology of ZL2014102801350940, discloses one improvethe tooth-brush handle of variable brush head angle, relates to scheme one and scheme two, comprises handle head and brush holder two parts, and wherein handle head makes the round clasp that two semicircular ring be made up of meshing with brush, and ring inwall makes a pair latch; Brush holder comprises the pincerlike formula that there is the monomer-type of tensioning groove on top and is integrally connected in intersection by axle by two handle bars; Pincer is rotationally connected into axle.Although brush can be realized to rotate in the round clasp of brush holder head, but in actual use, because the stability of brush is only by a pair latch clamping, do not use tighten up slide block just can not by steady for brush card, thus cause using inconvenience, brush holder makes the form of crossbar architectures, not only complex structure, cost of manufacture is high, more inconvenient in using.

Summary of the invention

The purpose of this utility model is to provide a kind of energy changing brush head and can becomes the toothbrush of brush head angle, and solve the complex structure existed in prior art, cost of manufacture is high, the poor stability that brush is combined with brush holder, inconvenient problem with use.

Technical scheme:

Energy changing brush head and the toothbrush that can become brush head angle, comprise brush holder and brush two parts, wherein brush holder and brush are respectively integrated, and brush active card is contained in the snap ring of brush holder; Snap ring is produced on the upper end of brush holder, and snap ring inner chamber makes regular polygon, and wherein the positive upper end open portion of snap ring accounts for a limit of aforementioned regular polygon or the space on two limits; The centre position of the edge of the positive lower end of snap ring is just to the tension force groove center line of brush holder having a long 3-20mm; Brush makes fusiformis, in the middle part of the brush back side inclined lateral location affixed one with the polygon prism of brush holder clamping.

Snap ring makes the shape of square, regular hexagon or octagon; The groove width of tension force groove is within the scope of 0.5-3.0mm; Polygon prism is the polygon prism of positive four ribs, positive six ribs or positive eight ribs.The lower end of polygon prism has a sectional dimension to be greater than the rounded stops of polygon prism, and rounded stops and polygon prism are made of one.

It is circular arc that brush makes both ends of the surface, and the affixed bristle of pore is opened in front; Brush holder makes evagination both ends, middle part adduction, has flexible arc, has elastic force, hold good stability time easy to use.

The polygon prism of brush is snapped in the snap ring of brush holder, by the tightening force of tension force groove, brush is clamped in snap ring, give the brush power that first rotates, make the as required rotation of brush in the snap ring of brush holder, reach the connection angle changing brush and brush holder, realize the different fit systems of the bristle on brush and tooth; Make the better effects if of brushing teeth.Brush can be changed on demand flexibly, and person easy to use selects the different brush of bristle stiffness to be arranged on brush holder to use.Only can also buy brush, be arranged on brush holder and use, save the material making toothbrush.

Detailed description of the invention

Below in conjunction with accompanying drawing, as embodiment, technical scheme is further illustrated.

With reference to Fig. 1,2,3, it is wide that brush holder 1 makes middle part, from middle part downwards gradually adduction narrow flat bar, the vertical bar shaped of width such as be upwards from middle part; Snap ring 3 is produced on brush holder upper end, and this example makes octagon snap ring 3, wherein wide two limits accounting for octagon, the space of the opening portion, positive top of snap ring 3.To open a business power groove 2 waiting on the center line heart line in the vertical bar shaped portion of width of brush holder 1, be communicated with snap ring, this example is made into the groove width of 1mm tension force groove 2; The length of tension force groove 2 adopts 20mm.Brush holder 1 is made from side to the Curved seen in there being radian, gripping time easy to use and operation, can form certain elastic force when brushing teeth.

With reference to Fig. 4,5, it is circular arc that brush 7 makes two ends, and middle part is wide and be the gradually little fusiformis of arc line shaped to two ends, and front has the pore of affixed bristle 8, is fixed in hole by bristle 8.The position that wide portion, the brush back side hits exactly inclined limit makes polygon prism 6, the rib number of polygon prism 6 and the regular polygon inner chamber of snap ring adapt, the cross-sectional area of polygon prism 6 and the inner cavity size of snap ring 3 coincide, and the distance between two ribs on polygon prism 6 and the edge 4 in snap ring 3 inner chamber adapt.The rounded stops 5 that a cross section is greater than polygon prism 6 is made in the lower end of polygon prism 6, integral with polygon prism 6; Rounded stops 5 makes to be arranged on after in the brush 7 in brush holder 1, and polygon prism 6 is limited in snap ring 3 to deviate from; This keeps off this block and does circular.

Namely an energy changing brush head and the toothbrush that can become brush head angle is made in the manner described above, during use, utilize the elasticity that brush holder 1 top tension force groove 2 has, the polygon prism 6 at the back side on brush 7 is clamp-oned in the snap ring 3 of brush holder upper end, brush 7 is just steady in snap ring 3 by card, according to when brushing teeth, and the angle of needs, rotate brush 7, can mode on request brush teeth; As also needed to change brush head angle in the process of brushing teeth, only need to hold out against slightly between brush 7 and tooth in conjunction with dynamics, rotate brush holder 1, the angle that brush coordinates with brush holder can be changed, then continue to brush teeth.Bristle 8 operating period on brush 7 is oversize, when needing changing brush head, changes a new brush, and does not need the new toothbrush buying whole handle.The production material of toothbrush can be saved.
