Description

Toothbrush head and use principle thereof

Technical Field

The invention relates to a toothbrush head and a use principle thereof.

Background

With the continuous progress of society, people have increasingly serious oral cavity problems mainly due to the diversification of diet and the untimely oral cavity cleaning, and the toothbrush is a common oral cavity cleaning product.

At present, the pasteurization method of tooth brushing is a widely accepted tooth brushing method, and the pasteurization method of tooth brushing, also called gingival sulcus cleaning method or horizontal vibration method, is a method recommended by the American dental society for effectively removing bacterial plaque near gingival margin and in gingival sulcus; when the toothbrush is used, the toothbrush and the long axis of the teeth form an angle of 45 degrees and point to the apical direction (the toothbrush is upward when the upper jaw teeth are brushed and the toothbrush is downward when the lower jaw teeth are brushed), the toothbrush inclines towards the junction area of the gum and the teeth, one part of the bristles enter the gingival sulcus, the other part of the bristles are paved on the gingival margin and extend into the gap between the gum and the teeth as far as possible, the bristles are horizontally vibrated for 4-5 times in the front-back direction in the original position by soft pressure, the toothbrush moves only about 1mm when vibrating, and 2-3 teeth are brushed each time; when moving the toothbrush to the next group of teeth, care should be taken to place the overlap.

Although the pasteurization tooth brushing method is an effective tooth brushing method, the brush heads on the conventional common toothbrush and the electric toothbrush in the prior art cannot be matched with the key required in the pasteurization tooth brushing method, because the heights of all the bristle tufts on the brush head of the conventional toothbrush are the same, when the bristle tufts in the middle of the brush head are obliquely pressed against the enamel surface of teeth, the bristle tufts on the upper side and the lower side of the brush head are partially or even not attached to the tooth crowns or the gums, so that only some bristle tufts in the middle of the brush head actually play a cleaning role, the cleaning range is small, and the brush head can frequently move between the teeth and the gums due to lack of positioning support when moving, the gap between the teeth cannot be effectively cleaned all the time, and therefore, the cleaning effect is poor; if the bristle tufts at the middle part of the toothbrush head are required to be attached to the enamel surface, the toothbrush needs to be continuously pressed with a large force, which is very inconvenient to use, and the bristle tufts at the lower side of the toothbrush head can cause gum damage due to excessive tightening of the gum, thus further improvement is needed.

Disclosure of Invention

In view of the current situation of the prior art, the technical problem to be solved by the present invention is to provide a toothbrush head which perfectly matches with the key requirements required in the pasteurization tooth brushing method so as to facilitate and save labor, thereby greatly improving the cleaning effect on the whole enamel surface and whole slit between teeth, effectively and accurately cleaning the gingival sulcus and gingival margin and expanding the cleaning range, and a use principle thereof.

The technical scheme adopted by the invention for solving the technical problems is as follows: a toothbrush head comprises a body and a brush part arranged at the end part of the body, and is characterized in that the brush part comprises a plurality of first tufts and a plurality of second tufts, the first tufts are arranged in a U shape and form a U-shaped tuft group, the opening of the U-shaped tuft group faces the root part of the body, and the second tufts are arranged in the U-shaped tuft group and are arranged along the axial direction of the body to form a linear tuft group; the first tufts have a height greater than the height of the second tufts.

Preferably, the difference in height between the first and second tufts is 2-3.5 mm.

(3) The reciprocating motion body brushes back and forth between a plurality of teeth with drive brush portion, because brush portion has relied on the upside and the linear type hair cluster of U type hair cluster respectively and has realized location and support respectively, thereby effectively injectd the activity direction of brush portion, and then make brush portion can not be vertical drunkenness when transversely brushing teeth, thereby make and be located a plurality of first hair clusters of U type hair cluster downside carry out accuracy and corresponding cleanness below in can all the time to the well below of dental crown outer wall and the inside of dental suture.

(4) Because the height of the second tufts is less than that of the first tufts, when the second tufts in the linear tufts prop against the middle upper part of the outer wall of the dental crown or extend into the middle upper part of the slit of the tooth, the first tufts on the upper side of the U-shaped tufts can incline and completely cover the top of the dental crown to enlarge the contact area with the top of the dental crown, thereby being more beneficial to brushing off tartar on the top of the dental crown.

(5) Because the height of the second tufts is smaller than that of the first tufts, when the second tufts in the linear tufts abut against the middle upper part of the outer wall of the dental crown or extend into the middle upper part of the slit, the first tufts on the lower side of the U-shaped tufts are inclined and embedded into the inside of the slit to the greatest extent, and then the second tufts in the linear tufts cooperate with the first tufts to effectively clean the inside and the periphery of the entire slit in all directions.

(6) When the brush part moves to a molar (namely an innermost tooth of the mandible) positioned at the innermost side, a plurality of first hair tufts positioned at the closed end of the U-shaped hair tuft group can stretch into the gap between the molar and the mandible and wrap the outer wall of one side of the molar in the gap by utilizing the U-shaped shape of the U-shaped hair tuft group, so that the gap and the outer wall are effectively cleaned.

Compared with the prior art, the invention has the advantages that: the upper side of the U-shaped hair cluster group and the linear hair cluster group respectively realize the positioning and the supporting of the hair brush part, thereby effectively limiting the moving direction of the hair brush part, further preventing the hair brush part from longitudinally moving when brushing teeth transversely, perfectly matching with the key required in the pasteurization brushing method and leading the use to be convenient and labor-saving; meanwhile, the plurality of first hair tufts positioned on the lower side of the U-shaped hair tuft group can always clean the middle lower part of the outer wall of the dental crown and the middle lower part in the slit accurately and pertinently, while the plurality of second hair tufts in the linear hair tuft group can also be matched with the plurality of first hair tufts playing a cleaning role to effectively and accurately clean the middle upper part of the outer wall of the dental crown and the middle upper part in the slit simultaneously, so that the cleaning effect on the whole surface of the dental crown and the whole slit is greatly improved, and meanwhile, the gingival sulcus and the gingival margin can be effectively and accurately cleaned; in addition, a plurality of first hair tufts which have the positioning function in the U-shaped hair tuft group can cover the top of the dental crown in a large area so as to be beneficial to the cleaning of the top of the dental crown, and a plurality of first hair tufts which are positioned at the closed end of the U-shaped hair tuft group can also extend into the gap between one innermost molar tooth and the mandible and cover the outer wall of one side of the molar tooth, which is positioned in the gap, so that the gap and the outer wall are effectively cleaned, and the cleaning range is expanded.
