Abstract
The utility model discloses a safety switch for separating electric heating water kettle, comprising a contact power switch fixed in the base of the separating electric heating water kettle. A switch activate key is arranged outside the base, and the switch activate key is connected with a push bar. The middle of the push bar is provided with a return spring, and one side of the front end of the push bar is fixedly provided with an elastic sheeting towards the contact of the contact power switch positively. The other side of the front end of the push bar is fixed a clip, and the front end near the clip is provided with a vertical contact bar. The contact bar is sheathed with the return spring, and the upper end of the contact bar extends to the upper surface of the base. The middle section of the contact bar is fixed to a transversal card, and the horizontal position of the transversal card is above the clip of the front end of the push bar. The utility model has the advantages of automatically cutting off the power supply of the coupler on the base after the water kettle remove from the base, making the coupler have no voltage, avoiding the dry burning of the water kettle, and ensuring safety.
Description
Technical field
The utility model relates to a kind of household electrical appliances safety switch, particularly a kind of safety switch that is used for the separate type electric kettle.
Background technology
The separate type electric kettle is because kettle can freely separate with base, and no matter use is to add water, and the boiling water that still falls is all very convenient, has therefore all obtained to use widely in family and hotel.But the separate type electric kettle that generally uses is not establish switch a bit at present, directly realize that by remove kettle from base outage stops heating, and kettle is placed on i.e. energising heating on the base, kettle appears in this technical scheme easily when running out and be placed directly in and switch on the base, causes dry combustion method; Though some separate type electric kettle is provided with switch, but switch is arranged on the kettle mostly, the closure of switch and disconnection have just disconnected the power supply of electric heater, and still there is voltage in the coupler on the base, after kettle is removed from base, the voltage of coupler is a unsafe factor on the base, and security incident takes place easily.
The utility model content
The purpose of this utility model provides a kind of kettle can the automatic disconnection base after removing from base on power supply on the coupler, make coupler no-voltage, can avoid the kettle dry combustion method, can guarantee the safe safety switch that is used for the separate type electric kettle.
The technical scheme that realizes the utility model purpose is: it comprises a contact power switch that is fixed in the separate type electric kettle base, outside base, be provided with a switch activated key, switch activated key is connected with a push rod, be provided with back-moving spring in the middle of the push rod, be fixed with over against the elastic pressuring plate of contact power switch upper contact on one side of push rod front end, be fixed with a buckle on the another side of push rod front end, front end near buckle is provided with a vertical feeler lever, be equipped with back-moving spring on the feeler lever, feeler lever upper end protuberate basic unit upper surface, the feeler lever stage casing is fixed with transverse card, and the horizontal level of transverse card is on the buckle of push rod front end.
In technique scheme, switch activated key is arranged on the side of base, can adopt the structure of pushing in base, switch activated like this key and push rod directly link together, during use, and directly inside push switch start key, push rod can travel forward, and finishes the task of closed power switch.Switch activated key also can adopt to the structure that presses down, can be connected by steering mechanism between switch activated like this key and the push rod, as structures such as turning-bar, cams, the motion that switch activated key is downward changes push rod motion forward into, finishes the task of closed power switch.Switch activated key also can adopt knob structure, also can be connected between switch activated like this key and the push rod by steering mechanism, as adopting domatic the contact between switch activated key and the push rod, or switch activated key adopts structures such as screw rod, rotatablely moving of switch activated key can be become travelling forward of push rod, finish the task of closed power switch.
The beneficial effects of the utility model are: it in use, when kettle is placed on the base, the kettle bottom promptly pushes feeler lever downwards, the transverse card in feeler lever stage casing is moved downward together until being in same horizontal plane with buckle, push or the rotary switc start key this moment, push rod is travelled forward, the contact that the elastic pressuring plate of push rod front end can push on the power switch of contact makes its closure, simultaneously, the buckle of push rod front end opposite side promptly is stuck on the transverse card of feeler lever, and power switch is kept closed; When with kettle when base is removed, feeler lever loses pressure, under the effect of feeler lever back-moving spring, upwards reset, transverse card on the feeler lever moves upward thereupon together, deviates from from buckle at last, like this, push rod is outwards motion under the effect of its back-moving spring, the contact that the elastic pressuring plate of push rod front end is promptly decontroled on the power switch of contact makes its disconnection, and power supply is cut off, no-voltage on the coupler on the base, safe and reliable, simultaneously, again kettle is placed on the base, as long as do not push or the rotary switc start key, power supply can be not closed, can dry combustion method even without water in the kettle yet.
