Liquid supplement mechanism and liquid cooling system

The present invention provides a liquid supplement mechanism and a liquid cooling system. The mechanism comprises housing, a cover body and a piston. The housing has a liquid outlet. The cover body is connected with the housing. A cavity is formed between the housing and the cover body. The cavity is communicated with the liquid outlet. The cover body has a first magnetic area. The piston can be movably arranged in the cavity. The piston has a second magnetic area. The position of the first magnetic area corresponds to the position of the second magnetic area, and the magnetic pole of one end, facing second magnetic area, of the first magnetic area is the same as the magnetic pole of one end, facing the first magnetic area, of the second magnetic area to generate magnetic repulsive force between the first magnetic area and the second magnetic area. 本发明提供种液体补充机构及液冷系统，包含壳体、盖体以及活塞。壳体具有液体出口。盖体连接于壳体。腔室形成于壳体与盖体之间。腔室与液体出口相连通。盖体具有第磁性区。活塞可移动地设置于腔室中。活塞具有第二磁性区。第磁性区的位置对应第二磁性区的位置，且第磁性区面向第二磁性区的端的磁极与第二磁性区面向第磁性区的端的磁极相同，使得第磁性
