Abstract

The utility model relates to the technical field of daily goods, in particular to a new type toothbrush with changeable brush head, which comprises a handle and a brush head that are combined flexibly. The front section of the handle forms a clamping opening that is provided with extension elasticity and can be used to embed or hold the brush head; a clamping position on the brush head combines with the clamping opening. The structure of the utility model needs not the processing of screws, thus simplifying the process lowering down the cost and realizing convenient assembly and disassembly as the extension function of the clamping opening can be utilized to embed or take out the brush head; the clamping opening holds the clamping part of the brush head in circular and larger contact area, thus realizing solid connection and preventing the loosening; the brush head can be conveniently replaced or cleaned.

Description

Novel toothbrush

Technical field:

The utility model relates to the daily living article technical field, refers in particular to the interchangeable novel toothbrush of a kind of brush.

Background technology:

Be prevention periodontal disease and health care tooth, brushing teeth with toothbrush is a kind of method that people use always; Current toothbrushes mainly contains electronic and manual two kinds, and in order to save material and to reduce cost, the toothbrush design that has is a combined type, and promptly brush is replaceable, can realize that like this a handle cooperates a plurality of brushes to use.For example one family only need be bought a handle, is equipped with a plurality of brushes again and gets final product, and during use corresponding brush assembling is connected on the handle, has scrubbed and has pulled down, and satisfies requirement in life and economically.The general employing is threaded yet existing brush and handle are connected, and uses a period of time, and screw thread very easily lost efficacy, and can't firmly connect, and also just caused toothbrush normally to use, and service life is low, and install, dismounting inconvenience, the connection stability shortcoming.

Summary of the invention:

The purpose of this utility model is to overcome the defective of prior art, provides a kind of simple for structure, easy accessibility, and connect the interchangeable novel toothbrush of firm brush.

For achieving the above object, the utility model comprises handle and brush, and both are movable combination, and the handle front end forms one to have the elasticity of receipts that rise and can be used for rabbeting folder mouth with the clamping brush, and brush has corresponding clamping part and folder mouthful to make up.

The clamping part of described brush is a cannelure, is positioned at the phase dorsal part of bristle.

Described folder mouth is the collar extension of a sealing, and the footpath is less than the external diameter of clamping part within the folder mouth.

Described folder mouth is made by the direct elongation moulding of handle.

Described folder mouth is by elastic component bending structure, and elastic component and handle are fixed with one.

The interior end of described ring gripping portion, be shaped to cancave cambered surface.

Be compared with the prior art, the above-mentioned novel toothbrush that provides is interlocking combination between its brush and the handle, and promptly the handle front end forms one and has the elasticity of receipts that rise and can be used for rabbeting folder mouth with the clamping brush, and brush has corresponding clamping part and folder mouthful to make up.This structure need not machining screw separately, and manufacture craft is simplified, and cost reduces, and utilizes rising of folder mouth to receive interlocking and the taking-up that characteristic cooperates brush, easy accessibility; Folder choma clevis is held the clamping part of brush, and contact area is big, connects firmly, is difficult for getting loose.

Description of drawings:

Accompanying drawing 1 is the utility model combining structure schematic diagram;

Accompanying drawing 2 is the utility model decomposition texture schematic diagram;

Accompanying drawing 3 is the structural representation of handle.

The specific embodiment:

Below in conjunction with accompanying drawing the utility model is described further:

See shown in the accompanying drawing 1～3, toothbrush described in the utility model comprises handle 1 and brush 2, both are movable combination, and handle 1 front end forms one to have the elasticity of receipts that rise and can be used for rabbeting folder mouth 11 with clamping brush 2, and brush 2 has corresponding clamping part 21 and folder mouthfuls 11 to make up.

The clamping part 21 of brush 2 is a cannelure, is positioned at the phase dorsal part of bristle, and the interior end of ring gripping portion 21 is shaped to cancave cambered surface.The madial wall of folder mouth 11 draws in the clamping cannelure just during assembling, and the cancave cambered surface of cannelure cooperates clamping, plays the effect of strengthening both chucking powers, thereby connection is more firm, and the cancave cambered surface of clamping part 21 also plays the effect of importing and derivation.

Folder mouth 11 is the collar extension of a sealing, and the footpath is less than the external diameter of clamping part 21 within the folder mouth 11.In the present embodiment, folder mouth 11 is non-circular, thereby also can not rotate after brush 2 interlockings, the clamping part 21 of folder mouthful 11 ring gripping brushes 2, and contact area is big, connects firmly, is difficult for getting loose.

Folder mouth 11 can be made by handle 1 direct elongation moulding, also can be by elastic component bending structure, elastic component and handle 1 are fixed with one, and make as adopting the resilient metal strip bending, and then be connected, or adopt other fixedly connected mode to connect with handle 1 injection moulding.

During installation, the clamping part 21 of brush 2 front by folder mouthfuls 11 is pressed into, utilizes the receipts elasticity that rises of folder mouthfuls 11, and clamping part 21 is a cannelure, during the clamping part 21 of the madial wall clamping brush 2 of folder mouthfuls 11, the effect of location is arranged just, and tighten up clamping brush 2 by folder mouthfuls 11, promptly finish interlocking.The left and right sides sidewall of clamping part 21 is connected to the left and right end portions of folder mouthfuls 11 just, and the external diameter of a side of being abutted against bristle of clamping part 21 is bigger, so that forms a top effect with the end of folder mouthfuls 11, and brush 2 is stressed when brushing teeth contracts in also not understanding, and structural behaviour is good.When unloading brush 2, only need oppositely extract and get final product, utilize the receipts elasticity that rises of folder mouthfuls 11, it is also quite convenient to extract, and is convenient to clean and replacement health, practicality.With respect to being threaded, its connection stability is better, and cost of manufacture is low, and is easy to use.
