Description

Brush hair district piece formula toothbrush head

Technical Field

The utility model relates to the field of daily necessities, more specifically say that it relates to a brush hair district piece type toothbrush head.

Background

The toothbrush comprises a brush handle and a brush head, wherein the brush head comprises a head shell with a cavity and a head sheet for covering one end of the head shell, and a plurality of through holes for inserting bristle tufts are formed in the head sheet.

The existing fixing modes of the hair bundle at the perforation of the head piece are divided into two modes, wherein one mode is as follows: the wool bundles are folded in half to form a V-shaped insertion hole, then a thin iron wire is pressed at the folding position of the wool bundles, and two ends of the thin iron wire are cut into the wall surface of the hole to fix the wool bundles, in this way, due to the fact that the wool bundles are folded in half and the iron wire is pressed at the folding position in the middle of the wool bundles, the folding position is bound to result in, namely, bristles cannot be formed at the iron wire position, after the wool bundles are inserted into the hole, the quantity of the bristles cannot be too dense, and due to the fact that the folding V-shaped insertion hole is formed, when the hole is not circular, but is perforated by an irregular polygon, the irregular polygon hole cannot be filled by the wool bundles folded in V, and the wool bundle fixing mode of the technology cannot meet the perforation form of the irregular. The other is as follows: the formula of cuting straightly, with the corresponding mode of tuft with the perforation shape, the disect insertion perforation, then the back is through the blanching process for the bottom of tuft carries out the heat fusion with the bottom of head board, and the tuft of this kind of technology, the brush hair on the perforation is intensive, and can adapt to the perforation of different shapes, and the commonality is higher when making the toothbrush head, can design more designs that accord with the anthropology.

However, in the toothbrush head according to the second design, although the tufts in the through holes are more densely arranged on the head piece and the insertion and fixation of the through holes with different cross-sectional shapes can be satisfied, the tufts are more easily dispersed in the portion with larger through holes, that is, the portion with more tufts.

SUMMERY OF THE UTILITY MODEL

The utility model aims at providing a technical ability adaptation can not hold the fixed brush hair of perforation cross-section, can reduce the toothbrush head that the tuft scatters the risk again.

In order to achieve the purpose, the method is realized by the following technical means: a brush hair sectional type toothbrush head comprises a head shell with an upper end opening and a cavity, and a head sheet used for covering the head shell, wherein a plurality of through holes used for fixing bristle bundles are arranged on the head sheet, and at least one bristle holding frame extending along the direction deviating from the head shell is arranged at the outer outline of the through holes.

The method is further optimized as follows: the hair supporting frame is preferentially arranged at the position of the perforated outer contour with the largest area.

The method is further optimized as follows: the through holes are arranged in a block mode and comprise peripheral block holes and inner peripheral block holes, when the bristle tufts are fixed in each through hole, the upper portion formed by the bristle tufts on the peripheral block holes is W-shaped when viewed from the side, and the upper portion formed by the bristle tufts on the inner peripheral block holes is arc-shaped and convex upwards.

The method is further optimized as follows: the hair supporting frame is arranged at the positions of the peripheral block hole close to the tip part of the toothbrush head and the inner peripheral block hole close to the tail part of the toothbrush.

The method is further optimized as follows: at least one bunch of hair bundles positioned on the peripheral block hole is provided with a mark color for prompting a user to replace the toothbrush.

The method is further optimized as follows: the shape of the through hole is a circle center or a regular polygon or an irregular polygon.

The method is further optimized as follows: the head piece is provided with a plurality of spaced welding posts for the one side of head shell, just the head piece is provided with the welding surrounding edge that encloses the inner wall block hole for the one side of head shell, when the hair bundle is fixed with the head piece, welding post, welding surrounding edge and hair bundle bottom all weld in the one side of the relative head shell of head piece.

Compared with the prior art, the utility model the advantage lie in: the straight-inserting type bristle mounting mode is adopted, so that the bristle quantity on the toothbrush head can be increased as much as possible on the basis of the same perforation area, and irregular or regular polygonal perforation except circular perforation can be adapted; the back of the head piece is provided with the welding column and the welding surrounding edge, so that the fixing capacity of the brush on the head piece can be improved; through holding up the hair frame, can improve the fixed height of hair bundle root, and then can play and reduce the problem that the hair bundle scatters after repetitious usage.

Detailed Description

The present invention will be described in more detail with reference to the following embodiments, which are illustrative only and are not limiting to the scope of the present invention.

Examples

A toothbrush head of a brush block type, see figures 1-5, comprises a head shell 11 and a head sheet 12, wherein bristles are fixed on the head sheet 12, the fixing mode of the bristles in the embodiment and through holes 121 of the head sheet 12 is a straight-line type, so that the quantity of the bristles in a single through hole 121 can be as large as possible, and the toothbrush head can be suitable for matching with various irregular polygonal through holes 121.

The tufts on the head sheet 12 are divided into peripheral tufts 21 and inner peripheral tufts 22, the upper curve of the peripheral tufts 21 in a side view is W-shaped, and the upper curve of the inner peripheral tufts 22 is convexly curved, so that when teeth are brushed, the teeth can be perfectly fitted to the teeth, especially the large teeth. The positions of the peripheral tufts 21 close to the tip end of the toothbrush head and the positions of the inner peripheral tufts 22 close to the tail end of the toothbrush head have the largest hole areas, so that the bristle supporting frames 122 are arranged at the outer contours of the through holes 121 at the two positions, the fixed areas of the roots of the tufts are increased by the arrangement of the bristle supporting frames 122, the risk that the tufts are scattered outwards is reduced, and the overall quality of the toothbrush head is improved. Of course, in addition to these two positions, the bristle support frame 122 may be provided at other positions of the perforation 121. Since the amount of bristles provided in the through-holes 121 having a large area is large and the risk of the bristles scattering is also large, it is preferable to provide the bristle support frames 122 at several positions where the area of the through-holes 121 is large.

The head sheet 12 is provided with a welding surface 125 opposite to the head shell 11 for fixing the hair bundle, a plurality of welding columns 123 are arranged on one side of the welding surface 125, a circle of welding surrounding edges 124 for surrounding the inner surrounding block through holes 121 are arranged, and after all the through holes 121 penetrate through the hair bundle, the root of the hair bundle, the welding columns 123 and the welding surrounding edges 124 are integrally welded on the welding surface 125 through a thermal welding process to realize the fixation of the hair bundle and the head sheet 12.

It is above only the utility model discloses a preferred embodiment, the utility model discloses a scope of protection does not only confine above-mentioned embodiment, the all belongs to the utility model discloses a technical scheme under the thinking all belongs to the utility model discloses a scope of protection. It should be noted that, for those skilled in the art, various modifications and decorations can be made without departing from the principle of the present invention, and these modifications and decorations should also be regarded as the protection scope of the present invention.
