Description

A kind of connection structure of electric toothbrush

Technical field

Electric toothbrush is the utility model is related to, especially a kind of connection structure of electric toothbrush.

Background technology

Existing electric toothbrush, its head toothbrushes are typically directly synchronous with the motor shaft engagement connection realization at driving handle end Movement, and the connection structure between head toothbrushes and motor shaft, should meet the structural strength that both connect, because of mistake when avoiding using Big vibrations cause head toothbrushes to separate with motor shaft to come off, and meet to be removed in cleaning, the requirement replaced again.

And head toothbrushes and structure that motor shaft is directly connected to need to meet excessively complicated during above-mentioned requirements, cause assembling not Just, and usually it is clamped the exposed globality for being arranged at toothbrush head surface, destroying appearance in position.

The content of the invention

For overcome the deficiencies in the prior art, the utility model provides a kind of connection structure of electric toothbrush.

Technical solution is used by the utility model solves its technical problem：

A kind of connection structure of electric toothbrush, including dismountable head toothbrushes and the driving handle for being built-in with motor, institute State driving handle and be extended with the motor shaft for driving the head toothbrushes to swing, the head toothbrushes include brush head main body and are fixed on institute State the connection plug of brush head body trailing end；The connection plug is equipped with elastic fastening hook, the elastic fastening hook can in the axial direction with Screens that the motor shaft is equipped with is two-way to be connected and fixed；The brush head main body, which is equipped with, meets that the elastic fastening hook can be elastic outwardly The clearance position of deformation.

The elastic fastening hook includes the support plate that the connection plug wall body is formed, and the support plate inner wall is raised to be equipped with and institute State the hook portion of screens clamping.

The screens is groove, and the hook portion section is arc.

The motor shaft is equipped with realize chimeric with the connection plug of notch and rotates synchronously；The screens annular is arranged on described Motor shaft outside diameter.

The inner cavity end of connection plug suit chimeric with the motor shaft is equipped with the through hole being in communication with the outside.

Sliding slot is equipped with the brush head main body；The connection plug outer wall is equipped with the convex ribs chimeric with the sliding slot；The brush Head main body is equipped with caulking groove, and raised be equipped with of the connection plug outer wall coordinates fixed abaculus with the caulking groove.

The beneficial effects of the utility model are：The brush head main body being mutually fitted and fixed with by the way that head toothbrushes are divided into and company Plug is connect, and the connection plug in brush head main body is equipped with the elastic fastening hook with the two-way clamping of motor shaft in the axial direction, makes toothbrush The motor shaft 3 that head is fitted axially on driving handle realizes both connect and fix, and ensures that head toothbrushes will not in normal use Depart from, and need to pull away under axial force effect during dismounting, cleaning, replacement easy to head toothbrushes, assembling is more simple Just, structural reliability is high；At the same time brush head main body be equipped with meet elastic fastening hook can elastic deformation outwardly clearance position, make elastic fastening hook It can hide and be arranged on brush head body interior, without exposed, presentation quality is more preferable for clamping position.

Embodiment

Referring to figs. 1 to Fig. 4, a kind of connection structure of electric toothbrush, including dismountable head toothbrushes 1 and it is built-in with motor Driving handle 2, driving handle 2 be extended with drive head toothbrushes 1 swing motor shaft 3, head toothbrushes 1 include brush head main body 4 and It is fixed on the connection plug 5 of 4 tail end of brush head main body；Connection plug 5 is equipped with elastic fastening hook 51, and elastic fastening hook 51 can be in the axial direction The screens 31 that is equipped with motor shaft 3 is two-way to be connected and fixed；The motor shaft 3 being fitted axially into when head toothbrushes 1 on driving handle 2 When, 51 elastically deformable of elastic fastening hook is clamped with screens 31, realizes the fixation of head toothbrushes 1 and driving handle 2, and need dismounting when It can be pulled away again under axial force effect, cleaning, replacement easy to head toothbrushes 1, assembling is more easy, and structural reliability is high； At the same time brush head main body 4 be equipped with meet elastic fastening hook 51 can elastic deformation outwardly clearance position 41, hide elastic fastening hook 51 and set Inside brush head main body 4, without exposed, presentation quality is more preferable for clamping position.

In the present embodiment, elastic fastening hook 51 includes the support plate 511 that the U-shaped hollow out of 5 wall body of connection plug is formed, support plate 511 Inner wall is raised to be equipped with the hook portion 512 being clamped with screens 31.Wherein, the screens 31 on motor shaft 3 is groove, the hook of elastic fastening hook 51 512 section of portion is arc, and when head toothbrushes 1 and the clamping of motor shaft 3, hook portion 512 can be caught in screens 31 along cambered surface, and in axis When being pulled open under outward force effect, hook portion 512 can depart from screens 31 along cambered surface.

512 cross sectional shape of hook portion is alternatively the triangle with front and rear two inclined-plane, can equally realize head toothbrushes 1 in axial direction It is different even by the gradient on two inclined-planes with the clamping of motor shaft 3 and pulling away i.e. on anteroposterior direction, clamping is adjusted with pulling away Required amount of force.

Further, motor shaft 3 is equipped with notch 32, and notch 32 is chimeric with connection plug 5 to realize motor shaft 3 and head toothbrushes 1 Rotate synchronously；On this basis, 31 annular of screens can be arranged on to 3 outside diameter of motor shaft, head toothbrushes 1 can be made in the equal energy of any angle It is enough to be connected and fixed with motor shaft 3, it is more easy without alignment, assembling.

With reference to Fig. 3, Fig. 4 and Fig. 6, motor shaft 3 and the chimeric requirement of connection plug 3 are extremely close, to avoid linkage status When both there is wide arc gap and cause larger operating noise.And after increasing connection plug 5,5 inner wall of connection plug and 3 outer wall of motor shaft Between may form sealing state, cause the air in connection plug 5 can not discharge and be difficult to normally assemble, therefore can connect The inner cavity end of plug 5 is equipped with the through hole 54 being in communication with the outside, and can be synchronously expelled from when motor shaft 3 stretches into the cavity of connection plug 5 Air in it, assembling are more light, reliable.

With reference to Fig. 5, Fig. 6, and be equipped with the fixed structure between brush head main body 4 and connection plug 5, including brush head main body 4 Sliding slot 42, and 5 outer wall of connection plug is equipped with convex ribs 52, convex ribs 52 are chimeric with sliding slot 42 to coordinate both axially positions of realization；Meanwhile Brush head main body 4 is equipped with caulking groove 43, and 5 outer wall of connection plug protrusion is equipped with abaculus 53, and above-mentioned abaculus 53 is fitted and fixed with realization with caulking groove 43 Radial positioning, make connection plug 5 fill in it is extremely difficult after brush head main body 4 be disassembled, just as in integrative-structure, reliability higher.

The utility model for the connection structure of electric toothbrush dens in dente brush head 1 and motor shaft 3, simply close by its technical solution Reason, and easy, reliability height is assembled, association area can be widely used in.
