Problems solved by technology

Unlike large-scale special-purpose machines that use steam pressure to separate coffee in a short time to obtain high-quality espresso coffee, existing small-scale espresso machines generally use mechanical force to convert pressure, and they all include a pressure generating device. During use, you need to use specific pressure
And for some users who are older or have less strength, it is difficult to use these pressure generating devices to obtain greater pressure in a short time, so it is difficult to obtain high-quality espresso

Embodiment 1

[0037] refer to figure 1 As shown, the pressure-adjustable portable espresso machine includes a columnar multi-section combined housing, and the combined housing includes a first shell segment 10 provided with a pressure output device, and a second housing segment provided with a water holding cavity 21. Two shell segments 20, and a third shell segment 30 provided with a coffee dissolving chamber 31. The first shell segment 10 , the second shell segment 20 and the third shell segment 30 are arranged longitudinally.

[0038] The first shell section 10 includes a cavity 11 with an open lower end. The water holding cavity 21 of the second shell section 20 has an open upper end. Wherein, a piston 40 is installed in the cavity 11 of the first shell section 10, and a piston 40 is provided outside the first shell section 10 for driving the piston 40 along the length direction (that is, the longitudinal direction) of the combined housing. The lever handle 50 that moves in the cavity...

Embodiment 2

[0050] combined reference Figure 4 As shown, the structure of this example is substantially the same as that of Example 1, and the only difference is that, in the water injection through hole 24, a tip extends downward from the lower end surface of the second shell segment 20, reaching directly to the coffee The first puncture needle 61 in the dissolution chamber 31. After the third shell segment 30 is assembled with the first shell segment 10 and the second shell segment 20 , the tip (not shown) of the first needle 61 extends into the coffee dissolution chamber 31 . The first needle 61 is axially provided with a first through hole (not shown in the figure) to connect the water holding chamber 21 and the coffee dissolving chamber 31; the hot water in the water holding chamber 21 flows through The first through hole enters the coffee dissolution chamber 31 . On the upper end of the coffee liquid outlet 32, a second needle 62 with the tip pointing up and extending to the insi...

Abstract

The invention provides a portable espresso coffee machine with adjustable pressure, which comprises a water holding cavity used for holding hot water and a coffee dissolving cavity used for extracting espresso coffee. The water holding cavity is provided with a piston which moves by tightly closing the inner wall of the water holding cavity, so that high pressure is formed by compressing a space for holding water in the water holding cavity, accordingly, the hot water in the water holding cavity is pressed in the coffee dissolving cavity, and simultaneously, high pressure is formed in the coffee dissolving cavity for extracting coffee. A coffee liquid outlet is opened on the coffee dissolving cavity, a pressure adjusting device comprising a rubber valve, an elastic accessory for supporting the rubber valve to plug up the coffee liquid outlet and an elastic control assembly for adjusting the elastic accessory to stretch and retract toward the liquid outlet is arranged to adjust pressure used for extracting coffee to acquire espresso coffee in the coffee dissolving cavity, and thereby different tastes of espresso coffee are prepared.

Description

technical field [0001] The invention relates to a coffee machine, in particular to a portable espresso machine. When preparing coffee, the internal pressure of the espresso machine can be adjusted according to needs, so as to obtain espresso with different tastes and meet the needs of different groups.
