Description
Technical field
It the utility model is related to a kind of feedwater coupler, more particularly to a kind of coupler for electric kettle.
Background technology
The electric kettle of self water feeding at present, typically entered by the upper connector and the lower connector on base of kettle body bottom
Row coupling, realizes electrical connection.Generally, no matter whether kettle body is placed on base, lower connector is typically all in energization
State, when water is spread across on lower connector accidentally, lower connector ponding and cause short circuit, although, can be in lower connector
Through hole is opened up on lower base and carries out draining, but lower connector still has a small amount of ponding or humidity and the potential safety hazard of short circuit be present.
The content of the invention
The technical problems to be solved in the utility model is to provide a kind of coupler for electric kettle, this to be used for electric heating
The coupler of kettle is more safe and reliable.The technical scheme of use is as follows：
A kind of coupler for electric kettle, including for the upper connector installed in kettle body bottom and for installed in
Lower connector on base, upper connector include upper pedestal, at least two conductive bulge loops, upper positioning convex ring, each conductive bulge loop,
Upper positioning convex ring from centre be arranged concentrically on outward on upper pedestal, lower connector include lower base, at least three times positioning convex rings,
At least two electrically conductive elastic contacts, each lower positioning convex ring is arranged concentrically on lower base outward from centre, two neighboring lower fixed
Annular groove is formed between the bulge loop of position, and electrically conductive elastic contact is arranged on corresponding annular groove bottom and relative with conductive bulge loop
Should, each annular groove is corresponding with each conductive bulge loop, it is characterized in that：Also include built-in switch, seesaw and back-moving spring；
Built-in switch is arranged on the base and the lower outer in the lower connector, and the inscribed end of built-in switch passes through wire
Electrically connected with the corresponding electrically conductive elastic contact；It is hinged in the middle part of seesaw in the outside of outermost lower positioning convex ring
On wall, one end of back-moving spring is connected with the lateral wall of lower positioning convex ring, and the other end of back-moving spring and the top of seesaw connect
Connect, the lower end of seesaw is corresponding with built-in switch position.
When kettle body is placed on base, each conductive bulge loop is in corresponding annular groove, the upper end of seesaw
Inwardly overturn under the compressing of upper positioning convex ring, the lower end of seesaw flips over touching built-in switch, is in built-in switch
On-state so that electrically conductive elastic contact and external power source are connected, each conductive bulge loop then with corresponding electrically conductive elastic contact
Contact with each other realization electrical connection；When kettle body is taken away from base, the lower end of seesaw is in the presence of back-moving spring to varus
Built-in switch is left out, built-in switch loses the active force of seesaw and is off, so as to disconnect each electrically conductive elastic
Electrical connection between contact and external power source, whole lower connector is not charged, therefore, even if misoperation and cause lower connection
The a small amount of ponding of device, short circuit will not also occur at lower connector, ponding can be removed in time, so as to normal use next time, and
And ensure that, when kettle body is taken away from base, each exposed electrically conductive elastic contact is not powered（220V civil power）, prevent life
Danger, more securely and reliably；Further, since the surface contact structure being engaged using conductive bulge loop with electrically conductive elastic contact, conductive
It will not be taken up between the side wall of bulge loop and lower positioning convex ring without close contacting fit, base with lifting for kettle body, base
It need not be made heavy, base can be made lighter and handier.
As preferred scheme of the present utility model, the madial wall of the upper positioning convex ring is provided with ground loop, the seesaw
For conducting strip, and seesaw is connected with ground wire.Using seesaw as ground connections so that kettle body by ground loop, lift up
Plate earthing, it is safer.
As the further preferred scheme of the utility model, the lower end outside of the seesaw is provided with insulation spacer；It is described
Built-in switch includes switch base, interior electroconductive elastic sheet and outer conducting strip, and interior electroconductive elastic sheet, outer conducting strip are mounted side by side on switch base
On.Above-mentioned interior electroconductive elastic sheet is the inscribed end of built-in switch, and outer conducting strip is the external connection end of built-in switch.Seesaw lower end is outside
Electroconductive elastic sheet in extruding, is bent outwardly interior electroconductive elastic sheet and is contacted with outer conducting strip and connect built-in switch during upset；When lifting up
Inwardly upset when leaving interior electroconductive elastic sheet under action of reset spring of seesaw lower end, interior electroconductive elastic sheet resetted under elastic force effect from
Over conducting strip, so that built-in switch be disconnected.Built-in switch is arranged to above-mentioned this structure, has good stability,
It is also comparatively simple in structure.
As the further preferred scheme of the utility model, interior contact is provided with the outside of the upper end of the interior electroconductive elastic sheet,
Outer contact is provided with the inside of the upper end of the outer conducting strip.By contact in being set on the outside of the upper end of interior electroconductive elastic sheet, lead outside
Outer contact is set on the inside of the upper end of electric piece, and the degree of crook of electroconductive elastic sheet, has more preferable conductive stability in reduction.
This coupler for electric kettle, by setting up seesaw and built-in switch, when kettle body is taken away from base
When, built-in switch loses the active force of seesaw and is off, so as to disconnect each electrically conductive elastic contact and external electrical
Electrical connection between source, whole lower connector is not charged, therefore, even if misoperation and cause a small amount of ponding of lower connector,
Also short circuit will not occur at lower connector, ponding can be removed in time, so as to normal use, and ensuring in kettle body next time
When being taken away from base, each exposed electrically conductive elastic contact is not powered（220V civil power）, prevent life danger, it is safer
Reliably.Further, since the surface contact structure being engaged using conductive bulge loop with electrically conductive elastic contact, conductive bulge loop and lower convex
It will not be taken up between the side wall of ring without close contacting fit, base with lifting for kettle body, base need not be made heavy, bottom
Seat can be made lighter and handier.
