Abstract
The invention discloses a base for an electric kettle. The base is provided with an outer annular boss, a middle annular boss and an inner annular boss and further comprises a waterproof cap. The waterproof cap comprises a connecting portion arranged on the middle annular boss, an outer waterproof portion arranged outside the connecting portion and having elasticity and an inner waterproof portion arranged inside the connecting portion and having elasticity. The outer waterproof portion and the inner waterproof portion are arranged obliquely downwards. An auxiliary annular boss protruding upwards is arranged in a null line jack. An annular water drainage hole is defined by the auxiliary annular boss and the inner waterproof portion. Looked from top to bottom, the outer waterproof portion covers a live line jack and the inner waterproof portion covers the null line jack along the portion over the water drainage hole; the outer waterproof portion deforms after receiving force and being extruded, so that the outer waterproof portion is attached to the outer peripheral wall of the middle annular boss; the inner waterproof portion deforms after receiving force and being extruded, so that the inner waterproof portion is attached to the inner peripheral wall of the middle annular boss. When the base for the electric kettle is used, the waterproof cap can prevent water from being splashed onto the live line jack and the null line jack and therefore the safety performance can be effectively improved.
