The utility model relates to the technical field of coffee machines, and discloses a manual coffee machine, comprising a liner, a coffee cup, a piston assembly and a driving rod. The driving rod is connected with the piston assembly and drives the piston assembly to rise and fall in the liner; the piston assembly separates an inner cavity of the liner into an upper cavity body and a lower cavity body; the piston assembly comprises a piston, a bracket and a valve core; the piston is provided with a water hole; and the valve core is limited and installed between the bracket and the water hole through the bracket. When the piston assembly rises and falls, the valve core unblocks or blocks the water hole. A pressure relief channel is arranged in the valve core; a port which communicates the pressure relief channel and the lower cavity body is a pressure relief port; a spring and a sealing body are installed in the pressure relief channel; and the spring is pressed against the sealing body on the pressure relief port. On the one hand, the valve core acts as a water valve switch; and on the other hand, the valve core can achieve the effect of decompression and protection. After water pressure exceeds a certain value, the pressure relief channel of the valve core is turned on to avoid an explosion accident caused by excessive water pressure in the lower cavity body; and the safety of the coffee machine is higher.
