Protector seat is made up of upper cover and lower cover, and have the circular hole of a up/down perforation in the middle of upper cover, the back side is provided with the installation cavity of a rectangle, and with circular hole UNICOM, for installing deadweight safety protection switch; The back side is peripheral and be provided with threaded mounting holes, for installation protector seat lower cover near near center location.Protector seat lower cover upper surface centre bit is equipped with a cylindrical boss, and its size is more smaller than the middle through circular hole of upper cover, and there is a screwed hole run through at boss center, for installing gravity regulator; Be arranged with feet outside the back side, each feet and protector lower cover immediate vicinity position are provided with threaded mounting holes, upper cover and lower cover are installed together by screw.
Deadweight safety protection switch is made up of lever, pin, gravity regulator, spring and sheet metal pack, lever one end is provided with hemispherical top, the hemisphere face of hemispherical top passes the circular hole in the middle of protector seat upper cover and is exposed at outside protector seat upper cover upper surface, the back side, hemispherical top is provided with a cylinder shape groove, for mounting spring; Be provided with circular hole in the middle of lever, be arranged in the installation cavity of protector seat by pin; After installation, the lever other end is positioned at below sheet metal pack.Gravity regulator is cylindrical-shaped structure, and cylindrical outer surface is provided with screw thread, is arranged in the screwed hole at protector seat lower cover boss center; Cylinder one end is provided with cylinder shape groove, for mounting spring; The other end is provided with yi word pattern groove, for the relative position regulating gravity regulator and lever to come directly towards.Sheet metal pack is made up of insulating base, insulation sleeve and two elastomeric sheet metals; sheet metal is arranged on insulating base; insulation sleeve is enclosed within outside whole sheet metal pack; play proof and electric leakage-proof safety effect; sheet metal pack is arranged in the installation cavity of protector seat by insulating base, and two sheet metals are connected with the double-end wire of live wire in power connecting plug respectively.
The protection circuit of power connecting plug, deadweight safety protection switch and wire composition deadweight protector, in power line power connecting plug, two wires are drawn at live wire two ends, are connected with two sheet metals in deadweight safety protection switch.The closed of two sheet metals is controlled by the lever of deadweight safety protection switch.
Deadweight protector advantage be economical and practical, cost is low, structure is simple, highly versatile, goes for multiple electrical equipment, especially electric kettle.There is applicability widely in average family.

Detailed description of the invention
With reference to shown in Fig. 5, for electric kettle, deadweight protector detailed description of the invention is:
Deadweight protector is kept flat, and feet down.The electric kettle filling water is placed on the protector seat of deadweight protector.Now, due to the gravity of kettle, the hemispherical top of deadweight safety protection switch lever one end can be pressed downwards, simultaneously the lever other end can upwardly sheet metal pack, and two metal sheets contact, thus connection live wire.Now again by the front end connecting circuit power input socket of power connecting plug, rear end connecting power line output plug, has just connected power supply and electric kettle.
While the water level decreasing of electric kettle, the weight of whole electric kettle also can decline thereupon.When the weight of electric kettle drops to certain value, the elastic force of spring overcomes the weight of electric kettle, and upwards pushed away hemispherical one end of lever, the other end of lever moves downward thereupon.Sheet metal in sheet metal pack, under the elastic force effect of self, recovers home position, and namely two metal sheets separately, and protection circuit disconnects, thus plays the power-off protection effect to electric kettle.
The precompression of spring can be adjusted by adjustment gravity regulator, thus the power (gravity namely during kettle triggering power-off protection) of adjustment lever top jack-up kettle.
