1. A safety socket module, comprising:
a shell;
an upper cover, configured to cover the shell and provided with a plurality of jacks;
compartments, wherein a number of the compartments corresponds to a number of the jacks, each of the compartments is arranged in the shell and below a respective jack of the jacks, and an interior of each of the compartments is accessible from an exterior of the shell through the respective jack;
waterproof electrical connection switches, arranged in the compartments and configured to asynchronously control connection and disconnection of a circuit between a power supply and a plug of an electric appliance, wherein a connection part of each of the waterproof electrical connection switches connected to a conductor in a bottom of the shell and an exposed part of the conductor are covered with a waterproof insulating material for a waterproof treatment; and
lock control members, respectively arranged in the compartments and aligned with the jacks, and configured to clamp pins of the plug of the electric appliance and bias the waterproof electrical connection switches when the pins are inserted into the jacks, respectively, and disengage from the pins and reset the waterproof electrical connection switches when the pins are pulled out of the jacks, respectively, wherein a connection part of each of the lock control members connected to a conductor in the bottom of the shell and an exposed part of the conductor are covered with a waterproof insulating material for a waterproof treatment,
each of the waterproof electrical connection switches comprises an isolated waterproof chamber, and a movable contact piece and a static contact piece arranged opposite to each other in the isolated waterproof chamber;
the isolated waterproof chamber is configured as a fully sealed structure, and a contact surface of the isolated waterproof chamber that is biased by a respective lock control member of the lock control members is elastically deformable; and
the isolated waterproof chamber is a waterproof capsule, and the waterproof capsule comprises a capsule base and a waterproof rubber sleeve fixed to the capsule base;
the movable contact piece and the static contact piece are arranged inside the waterproof rubber sleeve and fixed to the capsule base by injection molding;
an insulating elastic piece is arranged between the movable contact piece and the static contact piece to assist and correct a deformation and a rebound of the movable contact piece and the static contact piece;
the movable contact piece and the static contact piece are respectively provided with contacts; and
the movable contact piece and the static contact piece are configured to contact with each other through the contacts
the movable contact piece is configured to contact with the static contact piece to switch on each of the waterproof electrical connection switches through biasing of the respective lock control member when the pins are inserted into the jacks, and move away from the static contact piece to switch off each of the waterproof electrical connection switches through resetting of the respective lock control member when the pins are pulled out of the jacks;
a waterproof pad made of an insulating material is arranged on the upper cover; and
the waterproof pad is configured to cover a part of the upper cover and expose the jacks, and is configured to fit with the plug of the electric appliance to prevent water from entering the compartments through a gap between the plug of the electric appliance and the upper cover when the plug of the electric appliance is inserted into the jacks, and block a communication of water between the pins of the plug on a surface of the upper cover.
