s2: fixing the middle bristles by using a metal sheet to prepare hair bundles, implanting the hair bundles into the middle implanted holes 3, fixing the peripheral bristles by using the metal sheet to prepare hair bundles, implanting the hair bundles into the peripheral implanted holes 4, and finishing the steps;
s3: preparing glue-injected wool materials, and stirring and mixing;
s4: preparing the glue-injected wool material in the step S3 into master batches by using an extrusion granulator;
s5: and (5) taking the master batch prepared in the step S4 as a material, performing injection molding on the injection bristles 5 on the peripheral implanted holes 4 through an injection mold, fixing the middle bristles by using a metal sheet to prepare bristle bundles, implanting the bristle bundles into the middle implanted holes 3, and finishing the step.
An electric toothbrush head made through above-mentioned step, when brushing teeth, the periphery brush hair of implanting in the pore is planted to the periphery of large aperture is many, because it is great with gum area of contact to restraint the brush hair greatly, consequently when the contact of gum frequently is restrainted to the hair, the hair is restrainted less to gum pressure, can also protect the gum when cleaning the gum, gum stimulation when reducing to brush teeth, and be equipped with a hair peak at least on the injecting glue hair, the hair peak of thin point is favorable to improving the clean dynamics to the tooth, injection moulding's injecting glue hair is many on the pore is planted to the periphery of large aperture, can also reduce the pressure that the gum received when improving clean dynamics. And the bristles implanted in the middle implanted pore with the small aperture are few, so that the small bristles can easily go deep into gaps between teeth, the dead angle position of the oral cavity can be well cleaned, and the cleaning power of the toothbrush is improved.
Further, as a preferred embodiment of the present invention, but not limited thereto, the glue injection wool material comprises, by weight, 96 to 98 parts of TPU, 1 to 2 parts of silver ion antibacterial agent, 0.5 to 1 part of sea salt, and 0.5 to 1 part of dispersant. Wherein the TPU is: the Shore hardness of the thermoplastic polyurethane elastomer raw material is 60A-85D. The silver ion antibacterial agent is: one of a silver zeolite antimicrobial or a silver soluble glass antimicrobial. The sea salt is: the edible salt prepared by seawater evaporation is ground to 1000-2000 meshes. The glue injection wool contains antibacterial agent and sea salt, and can protect gum and prevent bacteria from breeding. The dispersing agent is: one of polyethylene wax or polyester wax, preferably polyethylene wax.
Further, as a preferred embodiment of the present invention, the injection mold includes a mold body 61, a cavity 62 is provided in the mold body 61, and a dividing piece 63 for dividing the cavity 62 so that the injected bristles 5 molded in the cavity 62 are divided into a plurality of crests 51 is provided on the cavity 62. The glue injection wool has a multi-peak structure, 1-6 wool peaks can be realized by adjusting the structure and the size of the die cavity, and the softness of the glue injection wool can be adjusted by adjusting the structure of the die cavity, namely, the split sheet, so that the requirements of different consumers are met. The height of the bristle peak can be adjusted by adjusting the length of the dividing pieces, so that the softness of the bristles can be adjusted
Further, as a preferred embodiment of the present invention, but not limited thereto, the dividing piece 63 is connected to a side wall of the cavity 62 and extends from a bottom of the cavity 62 in an opening direction.
The implementation case is as follows: injecting glue wool in an injection molding mode on the peripheral planting holes, wherein the injecting glue wool has a double-hair-peak structure, the length of a single peak is 10mm, the length of bristles is 11mm, the middle planting holes are made of PBT (polybutylene terephthalate) sharpening bristles, and the filament diameter of the bristles is 0.15 mm.
Comparative example 1-nylon rounded bristle electric toothbrush head common in the market;
comparative example 2-large aperture bundle electric toothbrush head of the existing AFT technology on the market;
the comparison mode is as follows: randomly extracting 10 persons, and evaluating the interdental cleaning force and the gum pain feeling of the embodiment; the evaluation mode of the tooth slit cleaning force adopts a scoring mode, the difference value of the scores of each grade is 5 scores, the total score is 100 scores, and the final result is counted in an average score mode; the gum pain during tooth brushing is evaluated by adopting pain grade, the evaluation mode adopts scoring, the difference value of each grade is 1 point, the total score is 10 points, 1-3 points are respectively no pain, 3-5 points are slight pain, and more than 5 points are obvious pain;
evaluation results were as follows:
the working principle of the embodiment is as follows:
the invention provides an electric toothbrush head which comprises a toothbrush head body and a hair implanting surface arranged on the toothbrush head body, wherein a middle hair implanting hole and a plurality of peripheral hair implanting holes arranged around the periphery of the middle hair implanting hole are arranged on the hair implanting surface, the aperture of the middle hair implanting hole is smaller than that of the peripheral hair implanting holes, glue injection hair or peripheral brush hair is injected and molded on the peripheral hair implanting holes, and at least one hair peak is arranged on the glue injection hair. When brushing teeth, the periphery brush hair of implanting in the pore is planted to the periphery of large aperture is many, because the big brush hair of restrainting is great with gum area of contact, consequently when the hair is restrainted frequently in the gum contact, the hair is restrainted less to gum pressure, can also protect the gum when cleaning the gum, gum stimulation when reducing to brush teeth, and be equipped with a maofeng on the injecting glue hair at least, the maofeng of thin point is favorable to improving the clean dynamics to the tooth, injection moulding's injecting glue hair is many on the periphery of large aperture is planted the hair hole, can also reduce the pressure that the gum received when improving clean dynamics. And the bristles implanted in the middle implanted pore with the small aperture are few, and the small bundle of bristles can easily go deep into gaps between teeth, so that dead corners of the oral cavity can be well cleaned, and the cleaning power of the toothbrush is improved.
The invention also provides a manufacturing method of the electric toothbrush head, which comprises the following steps:
s1: making a toothbrush head body and entering the step S2 or S3;
