Description

A new type of toothbrush

technical field

The utility model relates to the field of oral care appliances, in particular to a novel toothbrush.

Background technique

Toothbrush, as one of the most basic oral care tools, plays a vital role in daily oral care. The bristles of existing toothbrushes are straight or concave, which is convenient for cleaning the lip and buccal surfaces and occlusal surfaces of teeth, but is not conducive to cleaning the lingual and palatal surfaces of teeth. On the lingual and palatal surface, the teeth are arranged in a concave shape, and existing toothbrushes cannot fit it well, especially the gaps between the teeth on the lingual and palatal surface are more difficult to clean. Clinically, more plaque and calculus can be found on the lingual and palatal surfaces of teeth.

Pasteur brushing method, also known as gingival sulcus cleaning method or 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, that is, the toothbrush and the long axis of the tooth point at the root tip at a 45° angle Orientation (maxillary teeth up, mandibular teeth down). The brush head and handle of the toothbrush on the market cannot be rotated, which is not conducive to the use of the Pasteur tooth brushing method. If the tooth brushing method is used to make the bristles and the tooth surface form an angle of 45°, the wrist of the person must be tilted and then bent outwards. The angle of lateral bending of the human wrist is very small, so outward bending of the wrist will cause the wrist to be compressed and feel uncomfortable, and then give up the method of brushing teeth, resulting in insufficient cleaning of the oral cavity and causing oral diseases.

Utility model content

In order to solve the deficiencies of the prior art, the utility model provides a toothbrush which can fully clean the oral cavity and is convenient to use.

The purpose of this utility model is achieved by the following technical solutions:

A new type of toothbrush, comprising a detachable brush handle and a brush head, the brush head includes a support portion with an open front end, the top surface of the support portion is a top sheet made of a flexible material, and bristles are fixed on the top sheet , the bottom surface of the support part is an outwardly convex arc surface, and the inside of the support part is detachably provided with a support piece, the bottom surface of the support piece is the same arc-shaped structure as the bottom surface of the support part, Slide grooves are symmetrically provided on the left and right sides of the inside of the support part, and protrusions matched with the slide grooves are provided on both sides of the support member.

Further, the front end of the support part is provided with notches on both sides with the same height as the chute, and the two sides of the support are provided with grippers stuck in the notches.

Further, the brush head also includes a connecting section integrated with the supporting part, an inserting rod is provided on the other side of the connecting section, the diameter of the inserting rod is smaller than that of the connecting section, and the inner side of the brush handle An accommodating hole for inserting the inserting rod is provided.

Further, eight evenly distributed convex ribs are provided on the peripheral side of the insertion rod, and a crossing matching with the convex ribs is provided on the inner wall of the accommodating hole.

Further, the opposite sides of the connecting section are provided with arc-shaped recessed areas, and the planes where the two recessed areas are located are perpendicular to the bristles.

The beneficial effects of the utility model are: the utility model adopts a detachable supporting member with an outwardly protruding arc surface, forcing the bristles to protrude outward, forming an outward arc structure, which completely fits the tongue and palate of the teeth The shape of the surface can better clean the gaps between the tongue and palate of the teeth and avoid the growth of bacteria; by changing the angle of the brush head, the toothbrush is more suitable for cleaning the oral cavity by the Pasteur brushing method, so as to achieve the purpose of thorough cleaning and ensure oral health.

detailed description

In order to make the purpose, technical solutions and advantages of the embodiments of the utility model more clear, the technical solutions in the embodiments of the utility model will be clearly and completely described below in conjunction with the accompanying drawings in the embodiments of the utility model. Obviously, the described The embodiments are some embodiments of the present utility model, but not all embodiments. The components of the embodiments of the invention generally described and illustrated in the figures herein may be arranged and designed in a variety of different configurations. Therefore, the following detailed description of the embodiments of the present invention provided in the accompanying drawings is not intended to limit the scope of the claimed invention, but only represents selected embodiments of the present invention rather than all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by persons of ordinary skill in the art without making creative efforts belong to the scope of protection of the present utility model.

As shown in FIG. 1 and FIG. 2 , it shows the overall structure of the new toothbrush provided by the embodiment of the present invention including a detachable brush handle 1 and a brush head 2 .
