Toothbrush handle and toothbrush

Abstract

The invention discloses a toothbrush handle and a toothbrush. The toothbrush handle and the toothbrush facilitate gingival sulcus dental plaque cleaning by users. According to the technical scheme, a toothbrush handle comprises a base capable of being held by a user, one end of the base is provided with a connecting end for mounting an external brush head, and the holding surface of the base is provided with a first extending surface and a second extending surface; on the cross-section diagram of the base, the first extending surface and the second extending surface are fundamentally symmetrically arranged long the central line of the base, the obtuse angle formed between the first extending surface and the central line ranges between 130 degrees and 140 degrees., and he obtuse angle formed between the second extending surface and the central line ranges between 130 degrees and 140 degrees; when the external brush head is mounted at the connecting end, the central line is fundamentally positioned onto the brush hair symmetric surface of the external brush head.

Description

technical field

[0001] The invention relates to a toothbrush handle and a toothbrush. Background technique

[0002] Brushing teeth is an important health care method for people to remove dental plaque, soft dirt and food residues and keep oral hygiene in life. Among them, the Pasteur brushing method, also known as the gingival sulcus cleaning method or the horizontal vibration method, is a method recommended by the American Dental Association to effectively remove plaque near the gingival margin and in the gingival sulcus. The long axis points to the root tip of the tooth at an angle of 45° (the upper teeth are up, and the lower teeth are down), so that a part of the bristles enter the gingival sulcus to achieve the purpose of cleaning the plaque in the gingival sulcus. The shape of the handle part of the existing toothbrush is not very conducive to the user's control or perception of the position and angle of the bristle part in the gingival sulcus, which is not conducive ...

specific Embodiment 1

[0037] Such as figure 1 As shown, this embodiment discloses a toothbrush handle 100 , which includes a base body 110 suitable for a user to hold, and one end of the base body 110 is a connecting end 120 for setting an external brush head 200 . recombine figure 2 As shown, a first extension surface 111 and a second extension surface 112 are provided on the handle surface of the base body 110. In the cross-sectional view of the base body 110, the first extension surface 111 and the second extension surface 112 are substantially along the centerline 130 of the base body 110. It is arranged symmetrically, and the obtuse angle formed between the first extension surface 111 and the centerline 130 is preferably in the range of 130°-140°, and the obtuse angle formed between the second extension surface 112 and the centerline 130 is preferably in the range of 130°-140° After the connection end 120 is provided with the external brush head 200 , the center line 130 is basically located...

specific Embodiment 2

[0045] Such as Figure 5 As shown, this embodiment discloses a toothbrush 300, which includes a brush head 310 and a handle 320. The brush head 310 is provided with bristles 311, and the handle 320 is provided with a first extension surface 321 and a second extension surface 322 on the handle surface. Such as Figure 6 As shown, in the sectional view of the handle 320, the first extension surface 321 and the second extension surface 322 are arranged substantially symmetrically along the symmetry plane 330 of the bristles 311, and the angle formed between the first extension surface 321 and the symmetry plane 330 The range is preferably 130°-140°, and the angle formed between the second extension surface 322 and the symmetry plane 330 is preferably in the range of 130°-140°. In this embodiment, both the first extension surface 321 and the second extension surface 322 are set as planes, the angle formed between the first extension surface 321 and the symmetry plane 330 is 135°,...
