Abstract: A small manual coffee maker includes: a cup body and detachable coffee brewing base. A body lower end is connected to the base. Water and pressure chambers are in the body. A coffee brewing chamber and coffee outlet passage are in the base. The body has a water inlet passage communicating with the pressure chamber and a water outlet passage communicating with the pressure and coffee brewing chambers. A water chamber bottom has a water inlet communicating with the water inlet passage. The water inlet passage has a water inlet one-way valve which can control the one-way flow of water from the water inlet passage to the pressure chamber. The water outlet passage has a water outlet one-way valve which can control the one-way flow of water from the pressure chamber to the coffee brewing chamber. The body has a piston rod with one end extending into the pressure chamber.

Abstract: A manual pressure type coffee maker includes an outer cup body, the outer cup body is provided with a cup cavity with an open end, and with an inner container that can be inserted into and pulled out of the cup cavity from the open end, the technical points are the inner container is provided with an inner container cavity for containing brewing materials, the inner container is provided with a sealing ring that separates the cup cavity to form a closed space, and a bottom of the inner container cavity is provided with a filter communicated with the closed space, when the inner container is pulled outwards, negative pressure is formed in the closed space so that liquid in the inner container cavity is sucked into the closed space through the filter. The invention can brew coffee by negative pressure with a simple structure.
