The specific embodiment

In Fig. 1,2,1-the-parts, 2-second parts, 3-the 3rd parts, 4-support, 5-plug, the 6-sealing ring, 7-spring, 8-push rod, 9-seal, 10-water inlet, 11-discharge outlet, the 12-inner chamber, 13-return spring, 20-cavity, 21-flowing water passage, 30-raw material cavity, 31-delivery port;

The device of preparation beverage extracting substance of the present utility model, comprise first parts 1, second parts 2, the 3rd parts 3, support 4 and seal (sealing ring 6 and seal 9), first parts 1 are connected with support 4, be provided with water inlet 10 and discharge outlet 11 in first parts 1, respectively the passway that enters and discharge as the water source of outside; Second parts 2 are arranged in first parts 1, and second parts 2 can move down or slippage by relative first parts 1; But the lower end of second parts 2 is provided with the cavity 20 of drinks raw material, the front opening of cavity 20, but second parts 2 also be provided with heat supply water by and enter the discharging device of cavity 20; The structure of discharging device has multiple, illustrated a kind of specific embodiment structure of the present utility model, discharging device is by the flowing water passage 21 that is arranged on second parts 2, reach plug 5, spring 7, push rod 8 compositions, plug 5 covers on the flowing water passage 21, and sealing flowing water passage 21 is only after plug 5 moves up, flowing water passage 21 could be unimpeded, water outlet when second parts 2 and 3 sealings of the 3rd parts.Under the effect of pressure, second parts 2 are when the slippage downwards of first parts, 1 inside, when the push rod 8 of discharging device touched the 3rd parts 3, second parts 2 and the 3rd parts 3 had formed closed chamber, at this moment, discharging device is in critical open mode, second parts 2 continue downward slippage, and push rod 8 is subjected to upwards active force of the 3rd parts 3, and push rod 8 is upwards passed plug 5, flowing water passage 21 is opened, and hot water enters the closed chamber of second parts 2 and 3 formation of the 3rd parts by this flowing water passage 21.

Second parts 2 and first parts 1 seal by seal 6, and second parts 2 and the 3rd parts 3 seal by seal 9.

The 3rd parts 3 can be fixed on the support 4, are provided with delivery port 31 but the middle ends of the 3rd parts 3 is provided with raw material cavity 30, the three parts 3 of drinks raw material, flow to the outlet of outside from this delivery port 31 as the beverage of last formation.

Second parts 2 and the 3rd parts 3 come open and close by return spring 13 and other external systems, the upper end of return spring 13 is pressed against on second parts 2, the lower end of return spring 13 is pressed against on the support 4, relies on the compression or the elongation of return spring 13, and second parts 2 are moved up and down; Coming the mode of open and close with external system is routine techniques, can not describe in detail at this with reference to prior art.

Seal if be equipped with the pack case of beverage raw material, be necessary so at second parts 2 needle point or other lancing device to be set, the pack case that can earlier beverage raw material be sealed punctures, to allow hot water to enter in the pack case, it is a routine techniques, can not describe in detail at this with reference to prior art.

The utility model operation principle and process are such:

Shown in Fig. 1～6, the packing material that at first will be equipped with the drink-extracting raw material is placed in the raw material cavity 30 of the 3rd parts 3, start water pump then, allow the hot water of pressure enter the inner chamber 12 of first parts 1 by first parts, 1 water inlet 10, under the effect of pressure, second parts 2 are in the 1 inner relative first parts 1 downward slippage of first parts, when the push rod 8 of discharging device touches the 3rd parts 3, second parts 2 and the 3rd parts 3 have formed closed chamber, at this moment, discharging device is in critical open mode (shown in Fig. 3,4); Second parts 2 continue downward slippage, and hot water enters closed chamber by second parts, 2 flowing water passages 21, flows through the beverage raw material such as the coffee that will extract, and last beverage then flows to the outside from the delivery port 31 of the 3rd parts 3.When second parts 2 with after the 3rd parts 3 contact, push rod 8 is subjected to upwards active force of the 3rd parts 3, and push rod 8 is upwards passed plug 5, and flowing water passage 21 is opened, first parts, 1 inner chamber 12 and closed chamber form a container, and hot water is unimpeded enters closed chamber (shown in Fig. 5,6).

Principle according to mechanics, directed force F 2 sizes on second parts, 2 tops are multiplying each other of first parts 1 inner chamber, 12 pressure and the second parts 2 top cross-sectional areas, be F2=P1*S2, and directed force F 3 sizes of the second parts bottom are multiplying each other of interior pressure of closed chamber and the 3rd parts top cross-sectional area, i.e. F3=P2*S3.According to the pressure of fluid in same confined space inside is consistent principle, therefore, and P1=P2.Second parts, 2 top cross-sectional area S2 are greater than the 3rd parts 3 top cross-sectional area S3 in the design, therefore, the directed force F 2 on second parts, 2 tops is greater than the directed force F 3 of second parts, 2 bottoms, so second parts 2 have the trend of downward slippage, therefore always, second parts 2 are by being pressed on the 3rd parts 3 tightly, second parts 2 and the 3rd parts 3 are locked each other, and the cavity 30 closed annular seal spaces that form a relative closure on the cavity 20 of second parts 2 and the 3rd parts 3 are shown in Fig. 2～6.

Embodiment of the present utility model can be incorporated on the coffee machine, if being equipped with the pack case of beverage raw material seals, be arranged on the needle point on second parts 2, poke pack case, the coffee machine legacy device, particularly water pot and heating element heater will be got in the chamber of placing packing material in the device for preparing beverage extracting substance with water pump with the water of heating, and hot water flows through the beverage raw material such as the coffee that will extract by flowing water passage 21, and last beverage then flows to the outside from delivery port 31.

After extraction finishes, open the valve B of discharge outlet, get rid of the press water of first parts, 1 inner chamber 12, second parts 2 are upwards promoted by return spring A, open second parts 2 and the 3rd parts 3.(or promote second parts 2 by external system, open second parts 2 and the 3rd parts 3).
