Specific embodiment
The following is specific embodiment of the invention and with reference to accompanying drawing, technical scheme is further described,
But the present invention is not limited to these embodiments.
Fig. 1-Fig. 4 is refer to, coffee machine of the invention at least includes casing, brewing cavity, conversion connecting rod, upper filter plate, lower filter
Plate.Specific each structure is described below.
Casing includes left socle 9 and right support 12, and the two fastens formation inside the casing of cavity, brewing cavity 200, conversion
Connecting rod 10, ejection connecting rod 11 and upper filter plate 1, lower filter plate 5 are respectively positioned in casing.
Wherein, conversion connecting rod 10 is approximate " Qian " character form structure, is hollow part in the middle of it, and two linking arms are stretched out in both sides,
One end outer surface being connected with middle part of each linking arm is provided with protruding column, the casing branch of the protruding column and corresponding side
The shrinkage pool connection of frame inner surface setting, forms pivot structure so that conversion connecting rod 10 can be around protruding column for axle is rotated.
The other end away from middle part of each linking arm its towards the inwall of hollow part be provided with to hollow part stretch into it is convex
Block.It is preferred that the projection is cylinder, and rectangular block is arranged with cylindrical bump so that the rectangular block can be around projection freedom
Rotate.
Brewing cavity 200 is located at the top of conversion connecting rod 10, and its top is the hollow inner chamber of top surface opening, for accommodating coffee
Coffee beans, coffee grounds are simultaneously brewageed.The bottom of brewing cavity 200 is located in the hollow part of conversion connecting rod 10, and brewing cavity 200 is outer
Its both sides of wall middle part are respectively provided with an inserted link 21.A chute is respectively equipped with the inwall of corresponding left socle 9 and right support 12, the cunning
Groove includes arc chute with longitudinal chute.Two inserted links 21 are inserted in two chutes and drive brewing cavity arcuately chute respectively
Moved with longitudinal chute.The axis of the inner chamber of brewing cavity 200 is the direction parallel to longitudinal chute.
Inserted link 21 is moved under the drive of conversion connecting rod 10 along arc chute and longitudinal chute.Specifically, brewing cavity 200
The side external surface of bottom two is respectively provided with a horizontal concrete chute 22, and the horizontal concrete chute 22 is in the inner chamber axis of brewing cavity 200 parallel to longitudinal direction
It is vertical with longitudinal chute during chute.
The projection and rectangular block of the foregoing both sides of conversion connecting rod 10 insert in the horizontal concrete chute 22 of respective side and can respectively
Transversely chute 22 is moved.Therefore, when external force rotates the protruding column of conversion connecting rod 10, the rectangular block of conversion connecting rod 10 exists
While movement in horizontal concrete chute 22, brewing cavity is driven to move up and down, and the inserted link 21 of brewing cavity 200 then limits brewing cavity 200
It is set tiltedly to be moved up and down along longitudinal chute.

The middle part of bar 300 is provided with a rotating shaft 330, and swing rod 300 is rotatably fixed on support 100 by the rotating shaft 330.
When brewing cavity 200 does not have started rising in predeterminated position, end and the thimble ends contact of underarm 320, this
When underarm 320 not to thimble apply pressure.
The end of upper arm 310 is extended with adjutage 311 to cavity direction is brewageed, and the end of adjutage 311 is upwardly formed actuation arm
312.Adjutage 311 is set and causes that brewing cavity can intersect during rising with actuation arm 312, brewing cavity is near actuation arm
After 312 side external surface intersects with actuation arm 312, brewing cavity continues to rise, and actuation arm 312 is outwards supported so that making
With arm with rotating shaft 330 as fulcrum.
When upper arm 310 is rotated, underarm 320 then applies pressure and causes that water intaking valve is opened to thimble.
Water intaking valve 400 also includes valve body 420, and body cavity is divided into front end thimble receiving portion 421, stage casing throat
422 with rear end valve element receiving portion 423.The diameter of stage casing throat 422 is respectively less than front end thimble receiving portion 421 and rear end valve element receiving portion
423 cause to be respectively formed step between stage casing throat 422 and front end thimble receiving portion 421 and rear end valve element receiving portion 423.
Valve element 430 and the valve core spring 440 supported with spool end, thimble are provided with rear end valve element receiving portion 423
410 with valve element 430 through being connected after front end thimble receiving portion 421 and stage casing throat 422, and thimble 410 is positioned at front end thimble appearance
Receiving the part in portion is also arranged with thimble spring 411.
The downside of rear end valve element receiving portion 423 is formed with water intake valve mouthful 450, and the upside of stage casing throat 422 is formed with into water
Valve delivery port 460.
Water intaking valve delivery port 460 is connected by conduit with brewing cavity 200.
Preferably, in order to prevent conduit because of bending and caused by water line block, conduit is additionally provided with anti-folding spring.
Further, coffee machine of the invention also includes ejection connecting rod 11, and concrete structure is as shown in fig. 6, including connecting rod
111st, push rod 112, pressing key 113 and ejection arm 114.
Connecting rod 111 is a round bar, and centre is connected with the push rod 112 perpendicular to connecting rod 111, the two of connecting rod 111
End end respectively along being extended with an ejection arm 114 perpendicular to the direction of connecting rod 111, each ejection arm 114 and push rod 112 it
Between be respectively provided with a pressing key 113, the bearing of trend of the pressing key 113 and push rod 112 or to eject arm 114 opposite.
Wherein, connecting rod 111 is installed to one end of two horizontal concrete chutes 22, and can be rotated around its axle, while can also prevent horizontal stroke
Skidded off to the rectangular block in chute 22.Push rod 112 is located between the hollow bulb of conversion connecting rod 10.
Also, ejection connecting rod 11 constitutes said external transmission mechanism to drive guide post 7 to move up and down.Specifically, lead
Through hole is offered to the end of bar 7, the end of push rod 112 is inserted in the through hole, and is pressed key 113 and then stretched out outside casing, is passed through
Pressing pressing key 113 causes that connecting rod 111 is rotated, and then drives push rod 111 to pull guide post 7 to move up and down, and realizes putting
Beans deslagging.It is respectively equipped with the position of left socle 9 corresponding with the ejection arm 114 of ejection connecting rod 11 both sides and right support 12 convex
Platform.Arm 114 is ejected when brewing cavity 200 rotates upward by conversion connecting rod 10 and crosses boss, both can be by pressing key 113
Lifting guide post 7.
After the completion of brewageing, the ejection arm 114 of pressing ejection connecting rod 11 so that push rod 112 drives guide post 7 and lower filter plate
Move axially upward, you can carry out deslagging or scrape slag.
Guide post 7 is pulled downward on after the completion of deslagging, by pressing pressing key 113 to playback.Coffee next time can be carried out to make
Make process.
Specific embodiment described herein is only to the spiritual explanation for example of the present invention.Technology neck belonging to of the invention
