Problems solved by technology

The bristles of traditional electric toothbrush heads are generally made of PA nylon, and the top of the bristles is generally rounded. The bristles are relatively hard, and the strong vibration of the electric toothbrush is superimposed. The toothbrush that uses this type of brush head for the first time is prone to sensitivity. People with periodontitis may even experience gum bleeding, which may easily cause consumers to resist the use of electric toothbrushes. In recent years, with the emerge

Embodiment example

[0063] Implementation case: Plastic injection bristles are injection molded on the peripheral hair planting holes. The rubber injection hairs have a double peak structure, the length of the single peak is 10mm, and the length of the bristles is 11mm. .

[0064] Comparison case 1-electric toothbrush heads with nylon round bristles common in the market;

[0065] Comparative case 2 - large-hole beam electric toothbrush heads with AFT technology on the market;

[0066] Comparison method: 10 people were randomly selected to evaluate the interdental cleaning power and gum pain in the above-mentioned implementation cases; the evaluation method of interdental cleaning power was in the form of scoring, and the difference between the scores of each grade was 5 points, and the total score was 100 points. The final results are calculated by means of average scores; the pain of the gums when brushing teeth is evaluated by the pain level, and the evaluation method is scored. The difference...

Abstract

The invention discloses an electric toothbrush head. The electric toothbrush head comprises a toothbrush head body and a bristle planting surface arranged on the toothbrush head body, the bristle planting surface is provided with a middle bristle planting hole, a plurality of peripheral bristle planting holes arranged around the periphery of the middle bristle planting hole, and glue injection bristles arranged on the peripheral bristle planting holes, the aperture of the middle bristle planting hole is smaller than that of the peripheral bristle planting holes, and at least one bristle peak is arranged on the glue injection bristles. The invention further discloses a manufacturing method of the electric toothbrush head. When the electric toothbrush head is used for brushing teeth, the large number of glue injection bristles are implanted in the large-aperture peripheral bristle implanting holes, and the contact area between a large bundle of bristles and the gingiva is large, so that when the bristle bundles are in frequent contact with the gingiva, the pressure of the bristle bundles on the gingiva is small, the gingiva can be protected while the gingiva can be cleaned, and gingiva stimulation during tooth brushing can be reduced.

Description

【Technical field】 [0001] The invention relates to the field of toothbrushes, in particular to an electric toothbrush head and a manufacturing method thereof. 【Background technique】 [0002] Along with the raising of people's daily life standard, electric toothbrush begins to popularize widely. An electric toothbrush is generally composed of an electric brush head and an electric toothbrush handle. The electric toothbrush handle has built-in batteries and other electronic components such as a vibration motor. head, so as to achieve vibration cleaning teeth. The bristles of traditional electric toothbrush heads are generally made of PA nylon, and the top of the bristles is generally rounded. The bristles are relatively hard, and the strong vibration of the electric toothbrush is superimposed. The toothbrush that uses this type of brush head for the first time is prone to sensitivity. People with periodontitis may even experience gum bleeding, which may easily cause consumers...
