Abstract
The utility model relates to an automatic cut-out for electric kettle for water in boiling, comprising a control box. Two spring pieces controlling to switch the power source are arranged in the box, and a detecting lever is arranged outside the box. One end of the lever is hinged on the projecture at the outside of the control box, and the other end is matched with an air exhaust opening on the electric kettle cover. The lever is movably connected with an ejector rod, and the ejector rod acts on the two spring pieces to control the switch of the power source.
Description
The utility model relates to a kind of automatic power-off protection device, and particularly a kind of insulating pot water is driven automatic cutout.
Have exhaust outlet on the common electrical kettle, or be equipped with on gas port and ring flute, after water was opened, steam ejection or send sound knew that just water opened, and this kettle does not often notice causing that because of people water dryouies, and heating wire burns out or kettle is crossed cause thermal damage.
Chinese patent discloses a kind of self-controlling electrothermal kettle (CN2051340U), and this kettle has two detecting elements, and one is the temperature-sensing probe that cooperates with exhaust outlet on the kettle shell, and another is the float of being located in the kettle, the structure more complicated, and circuit is more complicated also.
The purpose of this utility model provides a kind of circuit breaker of closing automatically after opening by mechanical movement principle control insulating pot water, and is simple in structure, makes, handling ease.
The utility model is realized by following proposal:
At detecting lever of control box peripheral hardware of the present utility model, the end of lever is corresponding with the puff prot of insulating pot, after water-in-kettle is opened, the steam ejection, promote an end movement of detecting lever, thereby cut off the power supply by controlling organization, on the control box of the present utility model ridge is arranged, one end of detecting lever is hinged with it, with connect a push rod versatilely on the detecting lever of the adjacent part of pin joint, push rod pierces on the control box, acts on the spring leaf in the control box, have the location slotted hole on the push rod, two binding posts are arranged in the control box, be connected to spring leaf and lead on each binding post, the locator that cooperates with above-mentioned location slotted hole in addition in the control box, above-mentioned two spring leafs cooperatively interact and constitute the position of the switch, and push rod acts on one of them spring leaf, control being switched on or switched off of two spring leafs.
The utility model compared with the prior art, structure is simpler, does not have complicated circuit, easy to manufacture, cost is low.
Fig. 1 is the schematic diagram of an embodiment of the utility model.
Embodiment: as shown in Figure 1, the utility model has plastics control box (9) in this example, be the rectangle opened upper end, its bonnet extends a projection (5), box has a detecting lever (3) outward, the one end is hinged on the projection (5), the other end is the probe that the steam vent (1) that covers with insulating pot matches, post a rubber (2) on the probe, vicinity is connected to a push rod (4) versatilely with the projection intersection on detecting lever, push rod (4) has a slotted hole (4a) near the upper end, detecting lever passes this slotted hole and realizes both flexible connections, push rod opens wide from control box and stretches in the box, two binding posts (20) are arranged in the control box, (21), two binding posts respectively connect a metal spring sheet (8), (7) and a lead (14), (16), two binding posts are fixed on the terminal plate (11), terminal plate (11) is by two bolts (15), (19) be fixed on the rear wall of control box, heater element that connects insulating pot of two leads, another root connects power line, push rod (4) middle part has location slotted hole (17), be provided with a bolt (19) with the push rod upright position in the control box, bolt (19) passes the slotted hole (17) at push rod (4) middle part, and bolt (19) is provided with a setscrew nut (18) near push rod.
Present embodiment makes the rubber (2) of detecting lever be pressed on the exhaust outlet (1) that insulating pot covers in use, two metal spring sheets (7), (8) contact at this moment, power connection, heater element (10) heating, treat water open the back steam go out from exhaust outlet (1), promote detecting lever (3), it is lifted, drive push rod (4) and lift, then spring leaf (8) resets, lead (16) and lead (14) disconnect, and then power supply is disconnected, stop heating.Only need depress detecting lever (3) just when recovering heating.
