Description

Toothbrush with adjustable and replaceable brush head

Technical Field

The invention relates to the technical field of oral health, in particular to a toothbrush with an adjustable and replaceable brush head.

Background

Dental calculus is a complex substance composed mainly of proteins and food residues in saliva, bacterial plaque, bacteria in the oral cavity and the like, and is mostly accumulated in a position where a salivary gland duct is opened, and the salivary gland duct is opened on the lingual side of the anterior mandibular teeth, so that most and thickest dental calculus on the lingual side of the anterior mandibular teeth of many patients is clinically seen. Plaque can lead to the development of gingivitis, periodontitis, and gum recession.

The existing structure that the brush hair is directly implanted into the plane hair-implanting surface of the brush head needs to use a Pasteur tooth brushing method during tooth brushing, namely a method recommended by the American dental Association for effectively removing bacterial plaque near the gingival margin and in the gingival sulcus, namely, the toothbrush and the long axis of the tooth form an angle of 45 degrees and point to the apical direction during tooth brushing, so that the brush hair partially enters the gingival sulcus, and is partially paved on the gingival margin and extends into an adjacent gap as far as possible, and the brush hair is horizontally vibrated for 4 to 5 times in a short distance in the front-back direction in situ by using soft pressure. However, many people do not know the correct brushing method, and the pasteurism method is difficult to master, and the brushing time is short, so that the ideal cleaning effect is not achieved, and finally calculus is accumulated.

The multi-head toothbrush and the toothbrush handle in the market are not adjustable, the overall shape of the toothbrush is fixed, the bristle planting surfaces are on the same horizontal plane, the position of the toothbrush head cannot be changed, and the front-back diameter of the multi-head toothbrush head is larger than the left-right diameter of the multi-head toothbrush head in the prior art. Toothbrushes of the above type are effective for cleaning most areas of the teeth but are not conducive to cleaning of the lingual area, particularly the lingual area of the anterior teeth. Meanwhile, the angle of the brush head of the existing toothbrush can not be adjusted, and the brush head can not be replaced, so that the existing toothbrush is not beneficial to environmental protection and causes resource waste.

Disclosure of Invention

In order to solve the above problems, the present invention provides a toothbrush with an adjustable and replaceable brush head, comprising a brush head, a handle and a knob; the knob comprises a rotating block and a central rod, the rotating block is a circular ring with a hollow inner part, threads are arranged on the outer surface of the rotating block, the central rod is arranged at the central position of the rotating block and is movably connected with the rotating block, the brush handle is connected with the central rod through a connecting column, and the rotating block is connected with the brush head; the turning block allows the brush head to rotate 360 degrees along the brush handle.
