25 are connected on positioning region 43.The outer surface of 42 roof of cover is the curved surface of indent, and the lowest part of curved surface is located at 42 roof of cover
Center, the center of 42 roof of cover is equipped with high-pressure water heating inlet 44, and the inner surface of 42 roof of cover is equipped with
Puncturing blade 45, after box body mounting base is pushed into pedestal 24,253 drive sleeve pressure head 251 of motor moves down, casing pressure head
251 contacted with cover 42 after push cover 42 move downwardly together, so as to which puncturing blade 45 be made to puncture coffee capsule 10, in order to
High-pressure water heating enters inside coffee capsule 10.
It will make following introduce to the method for work of the present invention coffee machine below.
The method of work of coffee machine includes the following steps：
Coffee bean is put into beans case 52, starts coffee machine, mill beans unit 5 is by coffee bean grinding into ground coffee.
Ground coffee is entered by powder feeding pipes 55 in coffee brewing box 3 from mill beans chamber 511.
After having sent ground coffee, motor 253 drives screw head 2531 to rotate, so as to which drive sleeve pressure head 251 moves down, and
Casing pressure head 251 is moved downward to casing pressure head 251 and is fitted close with coffee brewing box 3, and casing pressure head 251 is to powder feeding pipes 55
Free end apply pressure, powder feeding pipes 55 free end deformation and ground coffee outlet 552 sealing.
High-pressure water heating is sent into brewing unit 1 from the external port of the second lead 2514, followed by runner 254, screw 28
On blind hole 283, the through-hole 284 on screw 28, after runner 255, sprayed from the aperture of upper filter screen 26 into coffee brewing box 3.
The coffee liquid made is flowed out from the fluid hole of 3 bottom of coffee brewing box, and followed by box body accommodating chamber 221,
Runner 241, runner 231 and lift one's head from coffee flow 23 222 outflow of coffee flow outlet, user can export in coffee flow
Coffee cup is placed to take coffee liquid drink in 222 lower section.
In addition, the first connector may be gear, correspondingly, pressing device further includes the second connector, second company
Fitting is rack, and rack is fixed on the internal perisporium of casing pressure head and along being parallel to the axially extending of casing pressure head, gear with
Rack is meshed.The free end of deformed powder feeding pipes can also be clamped at compacting part and coffee brewing box peripheral wall it
Between.In addition, powder feeding pipes can also be connected with the hose made by flexible material by the hard tube that hard material makes and be formed,
Middle hard tube is fixed on as the fixing end of powder feeding pipes in mill body, and hose stretches into coffee brewing box as powder feeding pipes free end
It is interior.Said program can also achieve the object of the present invention.
Therefore the drive shaft of motor is threadedly coupled with casing pressure head, drive shaft drives during rotating and reverse
Casing pressure head moves back and forth up and down, and compresses the function of coffee brewing box downwards so as to fulfill casing pressure head, which compares
It is simple in structure with the prior art, it is easy to implement automation, and easy to maintain and use.
After a kind of coffee for packing style is put into coffee brewing box, coffee brewing box is installed to the box body of box body mounting base
In accommodating chamber, box body mounting base is pushed to be installed in pedestal from the side opening of pedestal, pressing device compresses downwards and is connected to coffee
On the peripheral wall of coffee case for soaking.Need replacing other kinds packaging style coffee when, pressing device unclamp coffee brewing box, by box body
Mounting base is extracted out from pedestal, and coffee and coffee brewing box type are replaced after cleaning box body mounting base.Pouring box of coffee-making machine it is mutual
Changing device can realize a tractor serves several purposes, and whether ground coffee either coffee capsule can brew out mellowness in a coffee machine
Tasty coffee adapts to the needs of Different Package mode.In addition, pressing device is connected on the peripheral wall of coffee brewing box thus will
Coffee brewing box compress, the stress of such coffee brewing box evenly, so as to prevent coffee brewing box damage.
After mill beans unit has sent ground coffee into coffee brewing box, compacting part moves down and compresses powder feeding pipes, will
The ground coffee exit seal of powder feeding pipes free end.When need continue send ground coffee into coffee brewing box when, compacting part to
Upper mobile powder feeding pipes restore shape under the action of elastic restoring force, and ground coffee outlet is opened, so as to fulfill the defeated of ground coffee
It send.The cooperation of compacting part and powder feeding pipes can prevent from pipeline and grind the ground coffee of beans intracavitary making moist bonding.
Beans case is removably secured with mill body to be connect, and can be easy to implement the clear of the recycling of coffee bean in beans case and beans case
It is clean.Upper mill beans wheel is removably secured with beans case to be connect, and lower mill beans wheel is removably secured with lower mill beans wheel mounting bracket and connect, just
It is cleaned and is assembled in upper mill beans wheel and lower mill beans wheel.The setting of spring clamping device is easy to implement between beans case and mill body
Tight fit.In addition, the adjusting of coffee powder fineness can be achieved in the rotation by beans case.
Finally it is emphasized that the foregoing is merely the preferred embodiment of the present invention, it is not intended to restrict the invention, it is right
For those skilled in the art, the present invention can have various change and change, all within the spirits and principles of the present invention,
Any modification, equivalent substitution, improvement and etc. done, should all be included in the protection scope of the present invention.
