Below in conjunction with accompanying drawing embodiment of the present utility model is described further.

Referring to illustrated in figures 1 and 2, pouring and boiling device comprises a sleeve rack, by forming upper stock 3 and lower 5 relative closing up of stock, establish the import 32 of putting into coffee capsule in the middle of the upper stock 3, if open or close the skateboard component of capsule import, comprise that one is located at the axial rail 30 on the stock 3, along axial rail 30 slide plate 2 that slides and the slide plate frame 1 that is fixed on the upper stock 3, and the extension spring 13 that is connected in slide plate both sides, 2 upper end and both sides, slide plate frame 1 lower end.Slide plate 2 slides up and down the import 32 that can open or close coffee capsule 8 at axial rail 30.

Referring to Fig. 1, Fig. 3 and shown in Figure 5, it is seal cover 11 in the upper end of sleeve rack, seal cover 11 upper ends are for advancing hot water tube chamber 12, establish sealing ring 10 and screen pack 9 in the seal cover 11, when being pushed into the summit on the sleeve chamber 4, coffee capsule 8 enters in the brewing cavity 40, the brewing cavity closed front import 32 and the outlet 52 of coffee capsule.Seal cover 11 by annulus convex surface 110 up and down and 111 with upper bush frame 3 and lower sleeve frame 5 on the chucking sealing, advance hot water mouth of pipe injection brewing cavity hot water.

Referring to Fig. 1 and shown in Figure 3, sleeve chamber 4 outer walls evenly distribute axial channel 43a and horizontal guide groove 43b are set, present embodiment is established four equally spaced axial channel 43a and horizontal guide groove 43b, the end of axial channel 43a and horizontal vertical handing-over of top of guide groove 43b, and four horizontal guide groove 43b end directions are identical.A lateral projections 41 is established in the top of axial channel 43a, establishes two symmetrical ports 42 at the top end face in

sleeve chamber

4, and 4 tops, sleeve chamber are brewing cavity 40, and coffee liquid flows out from the liquid outlet 44 of cavity of resorption.

Referring to Fig. 3, Fig. 4 and shown in Figure 5, two guide pads are respectively established in the below of upper stock 3 and lower stock 5 inwalls, upper stock 3 inwalls below is respectively

guide pad

31a and 31b, lower stock 5 inwalls below is respectively

guide pad

51a and 51b, respectively with sleeve chamber 4 outer walls on axial channel 43a and horizontal removable contact of the corresponding fit of guide groove 43b.

Present embodiment is to establish gathering sill 43 at sleeve chamber 4 outer walls, also can be located at gathering sill 43 on

sleeve rack

3,5 inwalls, also can sleeve rack 3, the guide pad 31,51 on 5 inwalls is located on the outer wall in sleeve chamber 4.

The end of horizontal guide groove 43b outside the present embodiment sleeve chamber all points to clockwise, it is the fit locking state when rotating counterclockwise, also can all be made as the end of horizontal guide groove 43b counterclockwise, clockwise rotate and be the fit locking state, the present embodiment anglec of rotation is 39～40 degree, decides according to design cylindrical shell size.

Referring to Fig. 6, Fig. 7 and shown in Figure 8, symmetrical support bar 6 comprises strut head 60, straight-bar 65 and bar tail 64, support bar tail 64 is fixed on the sleeve rack left and right sides, strut head 60 is clamped in the left and right sides window of sleeve rack outer wall up and down by torsion spring 7, strut head 60 upper limbs are provided with the clip tooth piece 61 that withstands coffee capsule 8, the centre of strut head 60 is the arcwall face 62 of holding coffee capsule, and the arcwall face lower edge is the arc surface 63 corresponding with brewing cavity 40 outer walls.

Shown in Fig. 3,4,5,8, when sleeve chamber 4 was drawn out to loading and unloading capsule position, brewing cavity 40 was in the sleeve rack centre position, and sliding panel 2 is left behind, and opens capsule import 32 and puts into capsule 8.When axial advance is done in the sleeve chamber, the gathering sill 43a that guide pad 31a on the sleeve rack can be limited in sleeve chamber 4 can only axially move, when gathering sill 43a end touches sleeve rack guide pad 31a on the sleeve chamber 4, axially-movable finishes, at this moment sleeve chamber 4 can have been rotated, sleeve chamber 4 is rotated counterclockwise, guide pad 31a on the sleeve rack 3 will contact with the horizontal guide groove 43b end on the sleeve chamber 4, rotation is stopped, at this moment guide pad 31a has developed locking on the gathering sill 43b on the sleeve chamber 4 and the sleeve rack, sleeve chamber 4 limited chuckings can not move, be located on the sleeve chamber 4 other three guide grooves 43 also respectively with the horizontal guide block 31b that is located on the sleeve rack inwall, 51a and 51b phase cover locking.At this moment just formed the space of an airtight used for brewing coffee capsules between brewing cavity 40 and the seal cover 11.Left and right sidesing post 6 is to be connected with locating hole on the sleeve rack by afterbody 64, and support bar head 60 can move radially.Left and right sidesing post torsion spring 7 one ends are fixed on the sleeve rack, and the other end blocks support bar head 60, about two torsion springs 7 control respectively about the resetting of two support bars 6.Such as Fig. 5 and shown in Figure 8, after coffee capsule 8 is put into by capsule entrance 32, by the cambered surface 62 on the support bar head 60 capsule about 8 is clamped in the sleeve rack, when push ahead in sleeve chamber 4, capsule 8 enters brewing cavity 40 inside, brewing cavity 40 moves on, thereby the cambered surface 63 that can run on the capsule support bar head 60 struts left and right sidesing post 6, and capsule 8 enters into brewing cavity 40 inside fully.After finishing when infusing coffee, return in sleeve chamber 4, and at this moment left and right sidesing post 6 is stuck in capsule at breach 42 places on the brewing cavity 40 at the effect clip tooth piece 61 of left and right sides torsion spring 6, shown in Fig. 8 c.Pull on the moving sleeve chamber, at this moment capsule 8 is pulled out in brewing cavity 40 under the effect of left and right sidesing post head-clamp tooth piece 61, and exports 52 discharge pouring and boiling devices from capsule.As shown in Figure 5, sleeve chamber 4 when withdrawing from, the boss 21 on the slide plate 2 about tightly withstand lateral projections 41 on the sleeve chamber 4 under the effect of two extension springs 13, sleeve chamber 4 automatically resets under the thrust of slide plate 2.

The use procedure of this pouring and boiling device is as follows, at first just sleeve chamber 4 is rotated counterclockwise and pulls out, make brewing cavity 40 be in below, sleeve rack middle opening position, shown in Fig. 8 a, what at this moment coffee capsule 8 was passable puts into coffee brewing device from capsule entrance 32, the coffee capsule 8 right support bar 6 that keeps left is fixed in the sleeve rack, when promotion sleeve chamber moves axially, guide pad 31 at upper bush frame and lower sleeve frame, do rectilinear motion under 51 the restriction, in this process, the sleeve chamber struts left and right sidesing post 6 to both sides, and coffee capsule 8 enters into brewing cavity 40 inside fully, because the restriction of sleeve chamber axial channel 43, after rectilinear motion finished, the sleeve chamber can only turn clockwise, and rotation finishes, brewing cavity 40 is in sealing state with seal cover 11, and can carry out brewing of coffee this moment.Infuse coffee finish after, be rotated counterclockwise sleeve chamber 4, sleeve chamber 4 can be ejected into open position under the effect of the left and right sides of slide plate 2 extension spring 13, shown in Fig. 5 and Fig. 8 b, in this process, coffee capsule 8 can export 52 from capsule and discharge under the effect of left and right sidesing post 6, passes during brewing finishes, and can repeat top action as need again brewing.
