Abstract: A liquid storage and release chip provided according to the present application includes a structural layer and an elastic cover sheet. An end surface of one side of the structural layer is provided with a liquid storage cell and a liquid quantitation cell, the liquid storage cell and the liquid quantitation cell are separated by a common partition wall, and the partition wall is provided with a valve opening passing through end surfaces of two sides of the structural layer. The elastic cover sheet is attached to the structural layer and covers the liquid storage cell, the liquid quantitation cell and the valve opening in a sealed manner, and the valve opening allows a spool to be inserted in the valve opening in a sealed manner to push up a portion, covering the valve opening, of the elastic cover sheet.
