Description

Toothbrush with reinforced structure

Technical Field

The utility model relates to an oral care instrument technical field indicates a toothbrush with reinforced structure especially.

Background

Along with the improvement of living standard of people, the requirement on oral hygiene is higher and higher, so that the toothbrush is higher and higher in daily life. China is the country with the largest toothbrush output at present and is also the country with the largest toothbrush demand, and under the huge demand, the traditional toothbrush structure cannot meet the high demand of the toothbrush at present. The traditional toothbrush comprises a toothbrush handle and bristles, wherein the plastic toothbrush handle is firstly injection-molded by an injection molding machine through a mold, then the bristles are implanted into holes of the plastic toothbrush handle by a bristle planting machine, and metal sheets are implanted simultaneously, and the bristles are fixed in each hole of the plastic toothbrush handle by utilizing the extrusion force of the metal sheets with the diameter larger than the hole diameter on plastics.

At present, iron sheets are used for fixing bristles in domestic toothbrush production, and the method is different from the method that silver metal sheets with antioxidant reaction are used for fixing bristles in economically developed countries such as Europe and America. Iron sheets in the toothbrush rust due to chemical and oxidation reactions with elements such as water retained in bristles for a long time and sodium fluorophosphate in toothpaste after tooth brushing, and have adverse effects on human health in use; moreover, because the volume of the metal sheet for fixing the bristles is small and the extrusion force is limited, the bristles of the toothbrush often fall off when in use.

Disclosure of Invention

In order to solve the problems, the utility model provides a toothbrush with a reinforced structure, which has the advantages that the reinforced structure is arranged on the bristle planting plate, on one hand, the bristles can play a role of reinforcement when being connected with the bristle planting plate, so that the whole connection of the toothbrush is more stable; on the other hand, the traditional process of flocking by using metal sheets is abandoned, and the method is more environment-friendly and sanitary.

In order to achieve the above object, the utility model provides a technical scheme provide a toothbrush with reinforced structure, including brush head and brush holder, the brush head is connected with the brush holder, the brush head is including planting hair plate and brush hair, it is provided with the mounting hole that a plurality of can supply the brush hair to pass to plant the hair plate, it is provided with the reinforcement lug in the one side that deviates from the brush hair to plant the hair plate, the mounting hole is passed to the root of brush hair, it is located between each mounting hole to consolidate the lug, it is fixed with the root melting of brush hair to consolidate the lug.

As a preferred scheme, the outer edge of the hair planting plate is circumferentially provided with an annular bulge, and the annular bulge is embedded in the accommodating groove.

Preferably, the reinforcing protrusion comprises a plurality of semicircular protrusions which are uniformly distributed on the inner side wall of the annular protrusion.

As a preferred scheme, the reinforcing convex blocks further comprise a plurality of strip-shaped convex blocks, and the strip-shaped convex blocks are uniformly distributed on the hair-planting plate along the trend of gaps among the mounting holes.

As a preferred scheme, the brush holder is provided with the holding tank that is used for placing the planting hair board, the planting hair board pegs graft and passes through ultrasonic bonding fixed with the brush holder behind the holding tank.

The beneficial effects of the utility model reside in that:

the traditional toothbrush bristle planting process is characterized in that bristles are clamped on a bristle planting plate through a metal sheet, the reinforcing lug is arranged on the bristle planting plate, the reinforcing lug and the roots of the bristles are heated and melted into a whole, on one hand, when the bristles are connected with the bristle planting plate, compared with the situation that the bristles are simply and thermally melted on the bristle planting plate, the plane of a brush head after thermal melting is smoother, the reinforcing lug and the roots of the bristles are fused into a whole, so that the reinforcing effect can be achieved, and the integral connection of the brush head is more stable; on the other hand, the traditional process of flocking by using metal sheets is abandoned, and the method is more environment-friendly and sanitary.

Detailed Description

The invention is described in detail below with reference to specific embodiments and drawings.

Referring to fig. 1-3, the utility model discloses a toothbrush with reinforced structure, including brush head 1 and brush holder 2, brush head 1 is connected with brush holder 2, brush head 1 is including planting hair board 5 and brush hair 6, it is provided with the mounting hole (not shown in the figure) that a plurality of confession brush hair 6 passed to plant hair board 5, it is provided with reinforcing lug 3 to plant hair board 5 in the one side that deviates from brush hair 6, the mounting hole is passed to the root of brush hair 6, reinforcing lug 3 is located between each mounting hole, reinforcing lug 3 melts fixedly with the root of brush hair 6.

The traditional toothbrush bristle planting technology is to clamp the bristles on the bristle planting plate through the metal sheet, and the utility model discloses a be provided with the reinforcing lug 3 at the bristle planting plate 5, through heating and fusing the reinforcing lug 3 and the root of the bristles 6 into a whole, on one hand when the bristles 6 are connected with the bristle planting plate 5, compare with the simple hot melting of the bristles 6 on the bristle planting plate 5, the brush head 1 plane after the hot melting is more smooth, the reinforcing lug 3 and the root of the bristles 6 are fused into a whole and can play a reinforcing role, make the integral connection of the brush head 1 more firm; on the other hand, the traditional process of flocking by using metal sheets is abandoned, and the method is more environment-friendly and sanitary.
