Structure of brewing chamber of coffee machine
First Claim
1. A brewing chamber of the coffee machine, comprising:
- a cylinder body having a hollow room, which is used to put the coffee powder and brew the coffee;
at least one pipe in the bottom of said cylinder body, wherein one side of said at least one pipe is connected to said cylinder body and said pipe is passed through the hollow room; and
an intercepting device disposed within said pipe, wherein said intercepting device is used to let the liquid within the cylinder body to have a intercepting effect.

Abstract
An improved structure of brewing chamber of a coffee machine is disclosed by setting an intercepting device in an extracting pipe of a traditional brewing chamber of a coffee machine and two draining through-holes into the bottom of the traditional brewing chamber. Due to the intercepting device, the extracted coffee liquid coming from the brewing chamber can be drained off the extracting pipe with a stable speed and the coffee grain in the brewing chamber can be extracted in the conditions with an average extracting time and an average extracting pressure, and all that promote the extracting and tasting quality of the coffee. Besides, by the two draining through-holes, after all the extracted coffee liquid has been drained off the extracting pipe, the residual liquid in the brewing chamber can be drained off the brewing chamber smoothly to keep the next time extracted coffee liquid fresh.

11. The brewing device of the coffee machine, comprising
a brewing chamber having a cylinder body with a hollow room is used to put the coffee powder and brew the coffee; - at least one pipe in the bottom of said cylinder body and one side of said pipe is connected to said cylinder body and said pipe is passed through the hollow room; and
at least two draining through-holes disposed in said cylinder body and is used to release the residual liquid of said hollow room, and wherein said two draining through-holes are respectively passed through said cylinder body and connected to said hollow room;
a shaft passing through the shaft through-hole, wherein one side of said shaft is connected to the piston;
a piston having a plurality of filter holes, wherein said piston is disposed within said brewing chamber and is able to move in and out within said brewing chamber by pushing said shaft. When said piston is moved to the bottom of said brewing chamber, said piston can let the opening of said two draining through-hole close. And the liquid within said cylinder body can be flowed into said pipe from said plurality of filter holes.
- at least one pipe in the bottom of said cylinder body and one side of said pipe is connected to said cylinder body and said pipe is passed through the hollow room; and
-
13. The brewing device of claim 12, wherein said piston comprises a circle rubber ring. When said piston is moved to the bottom of said brewing chamber, said circle rubber ring let the opening of said two draining through-holes close. And the liquid within said cylinder body can be flowed into the center of said circle rubber ring and then to said pipe from said plurality of filter holes.
-
14. A method to let the extracting liquid of the brewing chamber of the coffee machine stable stably flow out, comprising:
-
providing a brewing chamber and wherein said brewing chamber has at least one extracting pipe, which is used to let the extracting liquid within said brewing chamber and flow out from said extracting pipe;
installing an intercepting device in the inside of said extracting pipe; and
when the extracting liquid is flowed into said extracting pipe from said brewing chamber, said intercepting device can be the stop for said extracting liquid and said extracting liquid can be flowed out from the surface of said extracting pipe. - View Dependent Claims (15)

16. A method to exclude the residual liquid with the brewing chamber of the coffee machine, comprising:
-
providing a brewing chamber, wherein said brewing chamber has a hollow room and at least one extracting pipe. And said brewing chamber is used to put the coffee powder and brew coffee;
disposing at least two draining through-holes in said brewing chamber and wherein said two draining through-holes are respectively passed through said brewing chamber and connected to said hollow room; and
when the extracting coffee liquid within said brewing chamber is excluded by said extracting pipe and there is some residual liquid generated within said brewing chamber. Because of the different pressure, the air in the outside of said brewing chamber can be entered said brewing chamber from one of said two draining through-holes and said residual liquid can be flowed out from the other one of said two draining through-holes.
