Description

A kind of toothbrush

Technical field

The utility model relates to a kind of toothbrush.

Background technology

At present the toothbrush body in the whole world is all made of plastics, mainly divides manual and electronic two kinds of toothbrushes.The plastic tooth brush of throwing away every year in China has caused nearly 12,000 ten thousand tons of white pollutions to environment, and As time goes on, this plastic pollution can be more and more heavier.Dissolve plastics and take 200 years left and right sides time in common soil, then need 100 years in the ocean, this still is the most secret estimation of authoritative scientist.The application designs new interface based on wooden and metal system toothbrush handle for this reason, and this interface not only ideally links together plastics brush and wooden or metal handle, and use is firm, easy to connect.

The utility model content

Technology of the present utility model is dealt with problems and is: overcome the deficiencies in the prior art, a kind of toothbrush is provided, this toothbrush is fixed, and is easy to use.

Technical solution of the present utility model is: the toothbrush that the utility model provides, comprise brush and handle, also comprise the interface unit that connects described brush and described handle, described handle top is provided with the handle grooves of holding described interface unit, described brush bottom has a thrust, this thrust to place in the interface groove on described interface unit top.

Further, the left and right sides antimere of described interface unit has two parallel penetrating pin-and-holes, a pin is installed in each pin-and-hole, also have spring eye on the described interface unit perpendicular to two pin-and-holes, the center line of the center line of described spring eye and described two pin-and-holes is on same cross section, a spring is respectively installed in the both sides of described spring eye, and an end of described spring withstands the pin in the described pin-and-hole, and the other end withstands the inwall of described handle grooves.

The thrust of described brush bottom is provided with draw-in groove, when described thrust places in the described interface groove, blocks described draw-in groove by described pin.

The diameter of described spring eye is greater than the diameter of described pin-and-hole.

Further, this toothbrush also comprises the base that is connected with described handle bottom.

Described handle is wooden.

Described handle is a metal material.

Described interface unit is a plastic material, preferred ABS material.

Described pin is the ABS material.

The utility model compared with prior art has following advantage:

The utility model connects brush and handle by interface unit, further have two parallel penetrating pin-and-holes at the left and right sides of interface unit antimere, a pin is installed in each pin-and-hole, also have spring eye on the described interface unit perpendicular to two pin-and-holes, the center line of the center line of spring eye and two pin-and-holes is on same cross section, a spring is respectively installed in both sides at spring eye, and an end of spring withstands the pin in the pin-and-hole, and the other end withstands the inwall of handle grooves.This structure has overcome the deficiency that existing toothbrush with replaceable head connects unstable (loosening easily) and installation course complexity, has advantages fixed, easy to use, environmental protection and energy saving (wooden and metal handle can use for a long time); As long as gently brush one is put, just brush and brush holder ideally can be coupled together, no matter how firmly to brush, brush can not shake and become flexible.

Interface unit of the present utility model and pin all are the ABS material, and nontoxic, odorless has shock strength and certain wearability preferably, also has excellent water tolerance and chemical stability.Spring adopts Stainless Steel 304 materials, not only anticorrosion, the anti-embroidery, and hygiene.

The specific embodiment

Below with reference to accompanying drawing the specific embodiment of the present utility model is described.

As shown in Figure 1, toothbrush of the present utility model, comprise brush 1 and handle 2, also comprise the interface unit 3 that connects described brush 1 and described handle 2, described handle 2 tops are provided with the handle grooves 6 of holding described interface unit 3, one thrust 5 is arranged at described brush 1 bottom, and these thrust 5 peripheries are provided with draw-in groove 9, and thrust 5 places in the interface groove 31 on described interface unit 3 tops.

The utility model is applied to the toothbrush interface with theory of mechanics, places two pins and two springs altogether.The left and right sides antimere of described interface unit 3 has two parallel penetrating pin-and-holes 32, each pin-and-hole is installed a pin 8 for 32 li, also have spring eye 33 on the described interface unit 3 perpendicular to two pin-and-holes 32, the center line of the center line of spring eye 33 and two pin-and-holes 32 is on same cross section (cross section of interface unit), a spring 7 is respectively installed in the both sides of described spring eye 33, the direct contact plug 8 of one end of spring 7, the other end directly contacts the inwall of handle grooves 6.When the thrust 5 of brush 1 bottom is put into the interface groove 31 on interface unit 3 tops, block the draw-in groove of thrust 5 peripheries by pin 8, two spring 7 meeting generation effects, two pins 8 are ejected, be pressed in 9 li of the draw-in grooves of brush base projections thing 5 firmly, brush and handle have just linked together tightly like this.
