Description

A kind of improved Moca coffee pot pressure valve

Technical field

The utility model relates to Moca coffee pot technical field, specifically a kind of improved Moca coffee pot pressure valve.

Background technique

With the raising of national life level, coffee making has gradually come into family from previous cafe, and Moca coffee pot is made For the container for most simply making coffee, it is very suitable to household person production coffee.

Moca coffee pot (Moka Pot) is a kind of for extracting the tool of concentrated coffee, universal in Europe and Latin American countries It uses, is referred to as " Italian type drop filter pot " in the U.S..

Moca coffee pot is double-layer structure, be placed on lower half portion boiling open boiling after, will be by netted equipped with ground coffee The top half of filter penetrating pot.Although using air pressure hot water can be injected in fineness grinding ground coffee in, it is tight This cannot be concentration-type extraction for lattice, but relatively leak through type, but the coffee that Moca coffee pot is made still has meaning big The concentration and flavor of sharp coffee Espresso.

Moca coffee pot currently on the market be divided to it is single press and double two kinds of pressures, single pressure is exactly traditional Moca coffee pot, point above pot, lower pot, Funnel, strainer, rubber ring.Double pressure Moca coffee pots are exactly that pressure valve, mesh are increased on pot core on the basis of singly pressing Moca coffee pot Be to increase pressure in pot so that coffee oil extraction is more abundant, allow coffee closer to the dense of Espresso Espresso Degree and flavor.Current dual-pressure valve door manufacturing cost in the market is higher, and structure is more complicated, although the quality of extraction coffee compared with Height, but the main product in market could not be become.

Moca coffee pot generates pressure extraction coffee, the coffee grease of the higher extraction of pressure is higher, quality using high-temperature heating It is just more preferable.Compared to traditional Moca coffee pot, dual-pressure valve structure Moca coffee pot pressure can achieve more greatly 2bar, and higher pressure energy is more preferable Extraction coffee grease.But dual-pressure valve structure Moca coffee pot higher cost currently on the market, and pressure can't perfectly extract Take coffee grease.So needing to improve in structure reduces dual-pressure valve structure Moca coffee pot cost, and increase pressure in pot.

Dual-pressure valve structure currently on the market, structure is complicated, higher cost.Increase a gravity valve on pot core, with This increases pressure in pot.When pressure is greater than valve gravity, valve can be opened, and coffee spills into pot.But it is existing Moca coffee pot gravitational pressure valve mechanism it is complex, as shown in Figure 1, its structure includes valve upper cover 1, valve lower cover 2, rubber Pad 3, pot core mouth 4, rubber ring 5 and upper pot pot core 6, since components are more, processing cost be will increase.

Pressure is determined by the area of spout and the Road of valve in pot.P=F/S, F, that is, gravity valve gravity, S that is, The area of spout water outlet.So pressure is directly proportional to gravity valve in pot, it is inversely proportional with spout water outlet open area.I.e. valve is got over Weight power is bigger, and the smaller pressure of spout is bigger.So needing to guarantee spout water-outlet area and weight valve when improving structure The weight of door., also can be bigger with regard to volume if pressure valve is heavier, the material cost of pressure valve also can be higher.

Utility model content

The purpose of this utility model is to provide a kind of improved Moca coffee pot pressure valve, to solve to mention in above-mentioned background technique Out the problem of.

To achieve the above object, the utility model provides the following technical solutions:

A kind of improved Moca coffee pot pressure valve, including valve upper cover and upper pot pot core, the upper pot pot core are fixedly installed on In upper pot；The valve upper cover is fixed at the top of valve inner core；The lower surface of the valve upper cover is fixedly installed with rubber Rubber mat.

As a further solution of the present invention: the knot that is integrally formed between pot on the upper pot pot core and Moca coffee pot Structure.

As a further solution of the present invention: the fixed form between the top and valve upper cover of the valve inner core Using threaded connection.

As a further solution of the present invention: being matched at the top of the rubber pad and the upper pot pot core.

Compared with prior art, the utility model has the beneficial effects that

When the utility model is used, valve inner core exists under the action of valve inner core and valve upper cover self gravity Upper pot pot in-core moves downward, and the dome top surface of rubber pad and upper pot pot core is in close contact at this time, and sealing effect is good, works as mocha When pressure under pot in pot is greater than valve self gravity, valve upper cover can be jacked up, and coffee spills into pot；In addition, by It is placed in upper pot pot in-core in valve inner core, coffee overflows in the gap between upper pot Hu Xinneiquan and valve inner core outer ring, makes It show that the gap of coffee is smaller, is more advantageous to the residue for filtering out coffee, the caffeol that the structure after testing surface modification is overflowed Rouge is more, and coffee purity is higher, almost without the residue of ground coffee.In conclusion the utility model can simplify dual-pressure valve door Structure reduces number of parts, reduces material cost, reduces assembly relation, effectively reduces the manufacturing cost of double pressure Moca coffee pots, right More preferable in coffee extracted effect, the coffee grease of spilling is more, and coffee purity is higher, effective cafe filter powder residue.
