Embodiment two

With reference to Fig. 4-6, the present embodiment carries out structure optimization on the basis of embodiment one, and the present embodiment is real using spinner structure The removable connection of existing capsule seat 3 and brewing seat 2, the disassembling operations of capsule seat 3 are more convenient, and the beverage making cavity of the two formation Leakproofness is also more preferable, specifically：The setting of 22 outer surface of brewing seat side wall screws slot 25, is set in 32 inner surface of capsule seat side wall correspondence Set spinner 33, spinner 33 moves along slot 25 is screwed, capsule seat 3 is screwed in brewing seat 2, it is contemplated that connection reliability and Operational comfort, spinner 33 and screws slot 25 and is arranged in pairs.The spinner structure can be multigroup, be 3 groups in the present embodiment, this The benefit of sample setting is can either to ensure that capsule seat is reliably easily installed and removed from brewing seat, and ensure that capsule seat is installed to Stability behind position can guarantee that capsule is motionless so that pricker reliably pierces through capsule when pricker pierces through capsule.

It is rotatably mounted in brewing seat 2 after capsule is put into capsule seat 3, then capsule seat 3, during this, brewing seat 2 On water inlet pricker 23 and draw pricker 24 will necessarily contact capsule sealer and be pierced through, this also means that user need pair Capsule seat 3 applies the power towards 2 direction of brewing seat, and as capsule pierces through compression to the end, it is desirable that above-mentioned power is increasingly Greatly.If screwing the too short of the design of slot 25, spinner 33 does not enter when screwing slot 25, intakes and pricker 23 or draws pricker 24 just Capsule sealer is contacted, this just needs user to 2 direction of brewing seat pressing capsule seat 3, is likely to result in machine movement, or even turn over It arrives, causes danger.If screwing the long of the design of slot 25, user needs to carry out multiple rotary manually, could revolve capsule seat 3 It closes in place, operation is not convenient enough.To solve the above-mentioned problems, the present embodiment screw slot 25 include helically extend screw and lead To portion 251, the helix angle for screwing guide part 251 is gradually reduced along 33 screw-in direction of spinner.

It should be noted that when spinner 33 contact and act on screw guide part 251 when, screw guide part 251 and also provide For one reaction force to spinner 33, when user's turn capsule seat 3, can obviously experience this reaction force, be oriented to due to screwing Portion 251 be spiral camber, screw guide part 251 offer reaction force can be decomposed into be directed toward brewing seat 2 axial force and with The opposite peripheral force in 3 direction of rotation of capsule seat, if the helix angle for screwing guide part 251 is too small, axial force is larger and circumferential Power is smaller namely rotational resistance is smaller, this can make user's operation more laborsaving, but can extend the length for screwing guide part 251, increases Add capsule seat 3 screws angle, is unfavorable for operating；If the helix angle for screwing guide part 251 is excessive, axial force is smaller and all Larger namely rotational resistance is larger to power, user's operation is relatively elaborate, and the self-lock ability for screwing guide part 251 is poor, rotation Button 33 easily loosens, and capsule seat 3 is caused to loosen.

Since the helix angle for screwing guide part 251 of the present embodiment is gradually reduced along 33 screw-in direction of spinner, work as glue When capsule seat 3 fastens to brewing seat 2, capsule is not clamped, it is desirable that rotary force it is smaller, just touched in spinner 33 and screw guide part When 251, since the helix angle for screwing guide part 251 is larger, the quick rotation of capsule seat 3 may be implemented in the spinning operation of user Into；As spinner 33 gradually screws journey after guide part 251, the helix angle for screwing guide part 251 is gradually reduced, this will have Conducive to the reaction force of reduction circumferential direction, while increasing the reaction force of screw-in direction, it is more advantageous under identical spinning force In the rotary motion for capsule seat 3, and providing larger pressing force makes capsule clamp, and so designs, reasonable distribution user's Rotary force, make capsule seat 3 quickly, swimmingly screw in brewing seat 2, operating handle is good and does not have interim card sense, and can be effectively Clamp capsule.

When specific implementation, the drop shadow curve of the guide part 251 after the expansion of 2 outer wall of brewing seat that screw of the present embodiment is two Secondary curve, or be formed by connecting by several sections of conic sections are tangent, such as circular arc, parabola, hyperbola etc., it can be ensured that curved surface Continuity, make the more smooth smoothness when being slided on screwing guide part 251 of spinner 33, operating handle is good, while also reaching can The purpose of helical angle gradual change.The design principle of guide part 251 is screwed according to the present embodiment, those skilled in the art can also arrive, Tangential can also be passed through by several sections of small line segments by screwing drop shadow curve of the guide part 251 after the expansion of 2 outer wall of brewing seat It is formed by connecting, when the camber line for connecting small line segment is sufficiently large, can also achieve the effect that the smooth sliding on it of spinner 33.

For ease of user's operation, it further includes screwing initial part 252 in circumferential plane to screw slot 25, to be revolved in capsule seat 3 Before conjunction spinner 33 can be resisted against to screw in initial part 252.The meaning that design screws initial part 252 is, is screwed in capsule seat 3 It is preceding to touch feel by screwing initial part 252 and spinner 33 feedback user that offsets, prompt user that can carry out screwing operation, and Position of the capsule seat 3 with respect to brewing seat 2 can be corrected, so that the two is kept coaxial or close to coaxial state, this is conducive to connect Get off the rotation of capsule seat 3, reduces operation difficulty.More preferably：By screwing initial part 252 spiral is additionally provided with towards opening portion direction The guide portion 2521 of extension, guide portion 2521 and screws and forms guiding port between guide part 251, and spinner 33 enters rotation from guiding port Guide part 251 is closed, is so designed, a larger guiding port can be formed close to the position of opening portion in brewing seat side wall 22, used When capsule seat 3 is buckled brewing seat 2 without making the alignment of spinner 33 screw guide part 251, spinner 33 can be along guide portion at family 2521 slide into and screw initial part 252, and slide-in of then taking advantage of a situation screws guide part 251, reduce operation difficulty.

In conjunction with Fig. 4,6, axial rotation when initial part 252 to capsule seat 3 screws in place is closed in the spin of spinner 33 of the present embodiment It is L5 into distance, it is L3, L5=L3 ± 3mm to draw pricker 24 and be pierced into the length of capsule, if L5-L3 ＞ 3mm, because capsule seals Pricker 24 is drawn when the ductility of film may cause capsule seat 3 to screw in place can not effectively puncture capsule sealer, if L3-L5 ＞ 3mm exceeds the extension limit of capsule sealer, causes capsule seat 3 to be brought out pricker 24 before screwing and push up partially, the utility model is set Meter ensure capsule seat 3 screw in place afterwards draw pricker 24 can effectively puncture capsule sealer while, make the 3 smooth rotation of capsule seat It closes.The length L3 of the piercing capsule of pricker 24 is drawn preferably in 5mm~15mm, then the spin of spinner 33 closes initial part 252 to capsule seat 3 Axial precession distance L5 when screwing in place is 5mm ± 3mm~15mm ± 3mm.
