Description
Technical field
The utility model relates to a kind of coffee machine, especially a kind of capsule type coffee machine that uses coffee capsule.
Background technology
Capsule type coffee machine is subject to vast welcome because of characteristics such as it need not to grind beans, brews conveniently, out taste of coffee brewing, uniform qualities.The structure of capsule type coffee machine and normal coffee machine are different, generally need a cover clamping mechanism to place coffee capsule, respectively there is lancing device at two ends---and puncture dials capsule is punctured, pass into the water under high pressure with certain temperature in capsule, just can realize the extraction of coffee.Traditional capsule type coffee machine adopts manpower extruding capsule to complete seal process, makes simultaneously to puncture dials and can puncture capsule, and this power needs larger; What pass into during on the other hand because of the capsule extraction is high-pressure water heating, and the pressure of whole system is increased, and can not leak for guaranteeing whole system, prevents hot water injury human body and the machine of HTHP, the necessary sealing load that strengthens.Therefore seek a kind of disengaging manpower extruding, and simple in structure, convenient, healthy, can carry out good sealing simultaneously, can normally extract coffee and a difficult problem that watertight coffee capsule clamping device is the technical staff always.Simultaneously for realize used coffee capsule can automatic trip from clamping device, be discharged to litter-bin, the technical staff has designed various automatic eduction gears, but without exception be all to have adopted a plurality of parts: as spring, slide plate etc., make whole clamping device very complicated, rate of breakdown improves greatly.
Summary of the invention
The utility model is mainly to solve coffee capsule clamping device complex structure of the prior art, need manpower larger during operation, and sealing force is little, simultaneously used capsule automatic eduction gear is complicated, the problems such as poor reliability, a kind of disengaging manpower extruding is provided, and simple in structure, convenient, healthy, simultaneously can provide larger sealing force, realize good sealing, can normally extract coffee and watertight coffee capsule clamping device, adopt simultaneously single component to realize that capsule discharges automatically, simple in structure, reliable capsule type coffee machine.
above-mentioned technical problem of the present utility model is mainly solved by following technical proposals: a kind of capsule type coffee machine, comprise coffee cartridge, pumping, control valve, boiler, water tank, piston push rod, back-moving spring, cylinder body, the cylinder body holder, spring base, the capsule support, guide rod, stand spring, the coffee cartridge protective sleeve, the piston rod packing circle, the water outlet silica gel, the water outlet spring, on, lower dials, upper dials holder and supporting seal etc., it is characterized in that in described capsule type coffee machine, cylinder body and cylinder body holder combine fixing, piston push rod is contained in cylinder body, outwards moved by the pumping driven plunger push rod of fetching water, spring base is fixed between guide rod and cylinder body holder, back-moving spring is arranged in piston push rod.during use, pumping is fetched water, control valve is got to logical position, water under high pressure enters and drives into the water end (W.E.) mouth, the compressing piston push rod travels forward, capsule is headed in coffee cartridge, on, lower dials punctures capsule, until piston push rod capsule is head-to-foot after, piston push rod can't travel forward again, pumping this moment continues to fetch water, whole system pressure is raise, the pressure that surpasses the one-way pressure valve of water outlet silica gel and water outlet spring composition, the water outlet silica gel is opened, after heating by boiler, water in pumping flows into hot water water inlet port, by the water outlet silica gel, upper dials enters capsule, begin to extract coffee, coffee flows out through lower dials and coffee cartridge.In the extraction process of whole coffee, water under high pressure is pushing away piston push rod always, and pressure is higher, and thrust is larger, and whole sealing system is in benign cycle, guarantees not occur to leak.After coffee extracted was completed, pumping stopped fetching water, and control valve is got to disconnected position, the water in cylinder body under the effect of back-moving spring through piston push rod drive into the water end (W.E.) mouth, get back to water tank by control valve.
As preferentially, described water outlet silica gel and water outlet spring fitting make whole system become more succinct at the top of piston push rod mouth.
As preferentially, describedly drive into the water end (W.E.) mouth and hot water water inlet port all is arranged on piston push rod, access of pumping water under high pressure out drives into the water end (W.E.) mouth, and after heat by boiler the other end, the access hot water port of intaking, improved mould structure.
As preferentially, described cylinder body adopts the stainless steel metal material, and when making control valve get to disconnected position, its discharge outlet can be connected to water tank, reaches water-saving purpose.
As preferentially, the position of catching on coffee capsule in the middle of described capsule support is more than half S type, both sides, up and down fluting, make it that good elasticity be arranged, distance between two positions is less than the size of capsule rib, and it is an inclined-plane that capsule is put into end, and the another side outlet side is the plane.A groove is arranged in the middle of the capsule support; distance from bottom is slightly less than the size of capsule rib; S type hook in the middle of when putting into capsule can block capsule; can be stuck in the fixed position; when piston push rod promotes the capsule support and capsule travels forward; after capsule enters coffee cartridge; the capsule rib props up the coffee cartridge protective sleeve; do not readvance; the segment distance and the capsule support can also advance under the effect of stand spring and piston push rod; the capsule rib is got out of the way in the distortion of S type hook, makes whole capsule support enter the back on capsule limit.After having extracted coffee, piston push rod retreats, drive capsule support rollback, the planar section of its S type hook promotes the capsule rib and withdraws from coffee cartridge, due to the capsule support rear, do not hold coffee capsule, coffee capsule is fallen into after withdrawing from coffee cartridge in scrap rubber capsule box, complete the function of automatic waste discharge capsule.
As preferentially, the pillar tail end that described capsule support is connected with piston push rod is a barb, the head chamfering, and middle fluting inserts in the hole of piston push rod, freely activity, but can not pull out, no longer need screw, simplified assembly technology.
As preferentially, the coffee cartridge protective sleeve of a circle metal is arranged outside described coffee cartridge, both closely cooperate.Protected on the one hand the security intensity of coffee cartridge under high pressure conditions; on the other hand because protective sleeve is thinner; be equivalent to strengthen the rib area of coffee capsule, the capsule support has improved contact area when discharging the scrap rubber capsule, make automatic this function of discharge scrap rubber capsule more reliable.
In sum, the utility model provides a kind of disengaging manpower extruding, and simple in structure, convenient, healthy, simultaneously can provide larger sealing force, realize good sealing, can normally extract coffee and watertight coffee capsule clamping device, adopt simultaneously single component to realize that capsule discharges automatically, simple in structure, reliable capsule type coffee machine.
