This invention provides a locking device sustaining high pressure in a coffee maker which comprises a brew head assembly which comprises: a slide assembly, a sealing assembly and a pop-up and roll-back assembly, operatively linked to sustain pressure up to four (4) bars. Furthermore, this invention provides a method for one-hand operation on the locking of a coffee maker comprising steps of: a) using one hand to pull a lever (1) forward to release a lock which is controlled by two parts, the slider (3) and the three mounts (17) on the brew head base (16), wherein the back-and-forth movement of the slider will produce the action of locking and releasing the brew head assembly; b) moving the lever forward; a push rod (2) assembled on the slider will push the slider forward and release the brew head; or pushing the lever back will push back the slider and lock the brew head; and c) after releasing the lock, the lift platform (10) will pop up assisted by the lift platform spring (11) and the lid mount roll up assisted by the hinge spring (13). <IMAGE> |
