Coffee machine high pressure filtering device capable of adjusting cup share

Abstract

The invention relates to a cup-adjustable high pressure filtering device for coffee maker, comprising a filter bowl and a filter cover. A diversion hole is arranged on the bottom of the filter bowl and the filter cover is provided with periphery folding upwards. A plurality of filtration holes are distributed evenly on the bottom of the filter cover. The high pressure filtering device is characterized in that the filter cover is matched with the filter bowl in a detachable mode and vertical through grooves are arranged on the outer wall of the filter cover periphery; at least two groups of projections are arranged on the inner wall of the filter bowl, which can insert into and move along the vertical through grooves of the filter cover, wherein, the each group of projections are arranged in the same horizontal circumference of the inner wall of the filter cover. The invention utilizes the through grooves and the projections arranged between the filter cover and the filter bowl to form a detachable match by inserting mutually and moving relatively, and uses the supporting limit to the filter cover coming from the next group of projections, so can adjust the coffee cups in a single filtering device. The cup-adjustable high pressure filtering device has the advantages of good economy and good convenience.

Description

technical field [0001] The invention relates to a coffee-making component, in particular to a high-pressure filter device for a coffee machine. Background technique [0002] The method of Italian-style high-pressure brewing coffee needs to be completed with the help of a special coffee machine. It is under a certain pressure, usually under the water pressure of 10 to 15 atmospheres, using water of about 95 degrees to brew the coffee contained in the filter device under high pressure in a short period of time. Get a full-bodied coffee. The filter device used therein needs to have the performance of filtering and high pressure resistance at the same time. At present, the filter device used in this type of coffee machine usually includes a filter cup and a filter cover; the filter cover is non-detachably fixed on the inner bottom of the filter cup, and a plurality of filter holes are stamped on it; the bottom surface of the filter cup is slightly lowered Convex, so that a ma...

Problems solved by technology

However, due to the non-detachable fit between the filter cover and the filter cup in the filter device, the amount of coffee it holds cannot be changed. For example, to brew a cup of coffee, you need to use a filter device with a volume of one cup. Two cups of filter devices, and so on, that is, according to the different amount of brewed coffee, multiple filter devices need to be equipped, which not only causes a certain amount of waste in the economy, but also brings a certain amount of trouble to the storage of items
