Description

Power interface assembly, power module and swimming pool cleaning robot Technical Field The application relates to the technical field of power interfaces, in particular to a power interface assembly, a power module and a swimming pool cleaning robot. Background In order to ensure the sanitary condition of the swimming pool, in addition to filtering and sterilizing the water of the swimming pool, the dirt attached to the surface of the swimming pool is cleaned. The surface of the swimming pool is cleaned by the swimming pool cleaning robot, so that the cleaning difficulty of the swimming pool can be effectively reduced. To ensure that the pool cleaning robot is able to perform cleaning tasks continuously within the pool, the pool cleaning robot is typically provided with a lithium battery or other energy storage device. The part of swimming pool cleaning robot is also provided with a power interface, and when the swimming pool cleaning robot leaves the swimming pool, the power interface is electrically connected with a charging cable in a butt joint way, and charging current is input to the energy storage device through the power interface. However, since the water of the swimming pool contains chlorine and salt, when the swimming pool cleaning robot can be in the swimming pool, if the metal conductive terminal in the power interface is in contact with the water of the swimming pool, the metal conductive terminal is corroded or electrolytic reaction occurs, the integrity of the surface of the metal conductive terminal may be damaged, or the surface of the metal conductive terminal is covered by a substance with poor conductivity, so that the power interface may generate a large heating value in the charging process of the swimming pool cleaning robot, and the swimming pool cleaning robot is easily severely damaged due to high temperature. Disclosure of utility model In view of the above, the present utility model provides a power interface assembly, a power module and a swimming pool cleaning robot that can solve or at least alleviate the above-mentioned technical problems. The utility model provides a power interface assembly, comprising: A main joint disposed circumferentially at least partially therearound, an interior Zhou Cexian of the main joint defining an interior space; At least two conductive terminals connected to the main joint and accommodated in the internal space; the base is connected with the main joint and is arranged around the periphery of the main joint; The sealing cover is provided with a closed end and an open end which are opposite, in the closed state, the sealing cover is in positioning connection with the main joint, the main joint is accommodated in the sealing cover, a first sealing piece is in circumferential abutting connection between the outer peripheral side of the main joint and the inner wall surface of the sealing cover, and a second sealing piece is in circumferential abutting connection between the open end and the base. The power interface component of the application, the conductive terminal is electrically connected to the energy storage device. In the uncapping state, the main joint is exposed out of the sealing cover, so that the main joint can be electrically connected with the external joint, and charging current is transmitted to the energy storage device through the external joint and the main joint. Under the lid state, the sealed relative position that keeps stable of main joint, and the open end and the base of sealed lid set up relatively, enclose and close and form confined space, main joint holding is in sealed lid, and two at least conductive terminal receive the enclosing of sealed lid and cover the protection.
