An electric kettle and its cover connecting device

Abstract

The invention discloses a flip connecting device. The device comprises a supporting base, a flip support arm which is fixedly connected to and used for supporting a flip, a rotating shaft which is directionally connected with the flip support arm and penetrates the supporting base, and an elastic rubber mat embedded in the supporting base and propped against the rotating shaft so as to decrease the rotating speed, wherein the rotating shaft is provided with an eccentric lug which corresponds to the elastic rubber mat in position and is interfered with the same, the interference amount of the eccentric lug and the elastic rubber mat is increased along with the reduction of the closing angle of the flip; the resistance of the elastic rubber mat retards the rotating of the flip, the eccentric lug is arranged to interfere with the elastic rubber mat, and along with the reduction of the closing angle of the flip, the interference amount, the rotary resistance and the balance torque are all increased, thereby slowly closing the flip at constant speed. The invention further discloses an electric kettle with the flip connecting device. The invention further discloses another flip connecting device and an electric kettle with the same, and a flip is slowly closed since an elastic rubber mat is arranged on a flip support arm to interfere with an eccentric lug on a supporting shaft for buffering.

Description

technical field [0001] The invention relates to an electric kettle, in particular to a flip connection device. Background technique [0002] At present, the flip cover of the electric kettle is generally opened more than 90° to maintain the open state. The general clamshell connection structure is a hinged structure without rotation resistance. When closing, you need to hold the clamshell down and close it gently, otherwise the clamshell will quickly close down and collide with the spout of the electric kettle, which will easily lead to damage to the clamshell. And produce impact sound. The reason is that during the closing process of the flip cover, due to the gravity effect combined with the ever-increasing moment arm during the flipping process, the closing moment and the acceleration of gravity continue to increase, which makes the closing speed increase rapidly, resulting in The moment of closing has a greater closing speed, thus resulting in a shock collision.

Problems solved by technology

The general clamshell connection structure is a hinged structure without rotation resistance. When closing, you need to hold the clamshell down and close gently, otherwise the clamshell will quickly close down and collide with the spout of the electric kettle, which will easily lead to damage to the clamshell. and make a knocking sound

The reason is that during the closing process of the flip cover, due to the gravity effect combined with the ever-increasing moment arm during the flipping process, the closing moment and the acceleration of gravity continue to increase, which makes the closing speed increase rapidly, resulting in The moment of closing has a large closing speed, thus causing impact collision

For the clamshell connection structure, general technicians consider using springs to buffer and decelerate, but when the spring strength is small, the buffer force is insufficient and the deceleration is not enough, and it is still unable to overcome the ever-increasing moment. When the spring force is large, it is not easy to close the clamshell, and Easy to shake repeatedly in the middle
