Abstract

A split toothbrush head intermediate is designed and manufactured into an integral part by a toothbrush head and a strip body, the strip body is used as a temporary 'accessory' for grabbing operation, and the toothbrush head and the strip body are cut off after hair planting is finished. The problem that the claw is not stable and is easy to jump is solved, the yield is improved, and the hidden trouble of safety production is eliminated. The toothbrush head has two pieces of bristles, so that the original tangent between one surface and the tooth surface is changed into the tangent between two surfaces and the tooth surface, and the acting point between one bristle surface and the tooth surface is changed into two acting points. The easy curling and skewing of the bristles at the acting force point are improved. The bristles with different lengths and shapes change the contact angle between the bristles and the tooth surface, so that the cleanliness of teeth is improved, and the auxiliary effect of reducing dental calculus and irregular teeth is achieved.

Description

Split toothbrush head intermediate

Technical Field

The utility model relates to a toothbrush, in particular to an intermediate body of a split toothbrush head and bristles.

Background

The traditional toothbrush bristles are all one piece and are produced in a bristle planting mode, and the projection of one side surface of the cross section of the traditional toothbrush bristles is more in a shape like a Chinese character 'yi', or is in a concave arc shape in the middle, or is in a wave shape, a sawtooth shape and the like. The manual split toothbrush adopts a toothbrush head and a handle structure which are connected in a rotating or pulling-inserting way.

Notice day 20100519 Notice No. CN201468392U, name: the examined Chinese utility model of 'toothbrush with detachable brush head' discloses a technical proposal of a split toothbrush, wherein a bulge is arranged on the brush head and is tightly matched with a corresponding hole on the brush handle.

Notice day 20100310 Notice No. CN201418488Y, name: the examined Chinese utility model of the 'special-shaped toothbrush' discloses a shape of toothbrush bristle, the front part of the bristle is 'high in the middle, the two sides are low' the rear part of the bristle is 'high in the middle, the two sides are low' in the left or right view on the main view.

The toothbrush head of the former technical scheme cannot be grabbed due to short and small size, the speed of the machine must be reduced when the toothbrush head is manually grabbed, the situation that the toothbrush head cannot be grabbed stably and slips or jumps is frequent, the yield is greatly reduced, the toothbrush head which slips and jumps hits and blocks directly faces the safety of people and machines, and the production is stopped without a proper manipulator. In addition, one side of the toothbrush head is provided with a bulge, the toothbrush head is fixed by the hair planting machine through surface veneering, the bulge clamps the middle part to generate seesaw action, the stability of fixation between two surfaces is reduced, and the fixation can be firm only by reforming a clamp. The latter solution aims at protecting the gums and it is unclear how to make such a profile hairiness.

Disclosure of Invention

The utility model aims at providing an intermediate and brush hair of components of a whole that can function independently toothbrush head can be grabbed firmly and put steady toothbrush head when making manipulator and manual operation, accomplish not reforming transform equipment also can normally process production not reduce output. The section of the tooth is increased by the structure and the hair shape of the brush hair; disperse pressure points of the tooth surface and the bristles, and increase the durability of the toothbrush and the tooth brushing effect.

In order to achieve the purpose, the toothbrush head and the strip body of the utility model are made into an integral part, the toothbrush head becomes an independent and complete part after the strip body is cut off, the center of the toothbrush head is provided with a connecting groove, two sides are respectively provided with an independent bristle mounting groove, and two independent bristles are formed after bristle planting, wherein the bristle shape is that the bristles are all equal in length, the side projection of the section is two straight lines in a shape of "-", the bristle shape is that the side projection of the section is two oblique lines in a shape of "\/", and the bristle shape is that the side projection of the section is two semi-circular arc lines in a shape of "∩∩".

According to the utility model discloses make into an organic whole part toothbrush head and a rectangular body design, the rectangular body is used for snatching the operation as interim "annex" and treats to plant the hair and excise it after accomplishing again. Because this "annex" structure, smooth solution the manipulator snatch the problem, solved artifical accurate operation, guaranteed the success rate and guaranteed output, reached normal operating requirement, eliminated the hidden danger of safety in production simultaneously, consequently need not to reform transform the instrument of snatching, the utility model discloses a toothbrush head center is a recess, does not have protruding pad between the toothbrush head back and machine face, so does not relate to mechanical fixture's transformation problem, and existing equipment can normally produce.

The two sides of the central groove are respectively provided with the bristle mounting grooves, so that the original one bristle is changed into two bristles, the original one surface is changed into two surfaces in a tangent mode with the tooth surface, the action force point of one bristle surface and the tooth surface is changed into two action force points, the easy curling and skewing of the bristles at the action force points are improved, the V/shaped bristles can play a role in deepening acute angles for teeth which are not arranged completely, the contact angles of the bristles and the tooth surface are changed by the bristles with different lengths and shapes, the teeth are more attached, the cleanliness of the teeth is improved, an auxiliary role is played in reducing dental calculus, and the use comfort of the toothbrush is also improved.

Detailed Description

The preferred embodiments of the present invention will be described below with reference to the accompanying drawings.

In fig. 1, when designing and manufacturing the toothbrush head 1, the toothbrush head 1 is attached with a strip body 3, and the strip body 3 is cut off as an intermediate body part after the whole production is subjected to the final hair planting and cutting operation, so that the toothbrush head 1 becomes a qualified product. The toothbrush head 1 center has a connection groove 6, both sides respectively have an independent brush hair mounting groove 4, generate two independent brush hair 5 after the planting hair, and toothbrush head 1 is connected with handle 2 through connection groove 6.

Figure 2 shows a bristle pattern of the brush of the utility model, two pieces are distributed on the toothbrush head 1
