Abstract: A water blocking member includes a fixed plate, a water baffle plate and a locking device. The fixed plate is rotatably connected to the water baffle plate. The water baffle plate and the fixed plate are locked and fixed through the locking device, and the locking devices configured to lock an angle between the water baffle plate and the fixed plate. Through the above structure, a user can fixedly place the fixed plate in a sink or a bathtub or any other position platform that requires water blocking. Under the locking action of the locking device, the water baffle plate is rotated to a locking position relative to the fixed plate. The water baffle plate is locked in a basically perpendicular state relative to the fixed plate.

Abstract: A battery apparatus includes batteries arranged in a first direction; an end plate disposed at an end of the battery apparatus and having adjacent third and fourth surfaces; a protective support disposed on the end plate and having adjacent first and second surfaces. The first and third surfaces are disposed opposite to each other, and the second and fourth surfaces face the batteries; the fourth surface has an adhesive layer; the protective support has a notch at a junction of the first and second surfaces, and the notch is a first notch, and/or the end plate is provided with a notch at a junction of the third and fourth surfaces, and the notch is a second notch; a first (first notch and third surface), second (second notch and first surface), or third (first and second notches) combination forms a groove, and an opening of the groove faces the batteries.

Abstract: A battery apparatus includes a plurality of batteries arranged in parallel, at least two busbars, and at least one temperature acquisition unit. In a stacking direction of the plurality of batteries, the temperature acquisition unit is arranged between adjacent two of the busbars.
