Description
Technical field
The invention belongs to the technical field of coffee machine, particularly relate to a kind of extraction module of coffee machine.
Background technology
Its structure of coffee machine mainly includes water pot, brewages unit, heating element heater and water pump etc., brewage unit and mainly comprise fixed extractor parts and mobile extraction parts, wherein fixed extractor parts are fixed on the front end in support, mobile extraction parts are arranged on the rear end in support, and can relatively slippage before and after fixed extractor parts, the slippage of mobile extraction parts to after contacting with fixed extractor parts between the two seal closure extract chamber to be formed to seal.Got to by the water water pump of heating during extraction in extraction chamber, the hot water of high pressure flows through the beverage packets that will extract, and by the coffee extracted in coffee pads out, last coffee beverage flows out for user from the outlet pipe of coffee machine.
The type of coffee pads mainly contains two kinds, and one is rigid coffee pads, and its body portion surrounding of coffee pads and annular edge, along making for rigid material, the front/rear end of coffee pads are densely covered with the pore supplying water and flow through, the high strength and deformation of this coffee pads; Another kind is then flexible beverage bag, as the beverage packets of non-woven fabrics or filter paper type, also E.S.E coffee pads is made (to be a kind of by ground coffee extrusion molding, similar pie, and have the coffee pads of certain degree of hardness), wrap filter paper more outside, filter paper coffee pads perimeter filter paper after hot pressing has certain hardness.
Existing mobile extraction parts are rigid plane with the end face contacted with coffee pads in fixed extractor parts, and at least the parts such as screen pack and flexure strip are set in the rigid plane of fixed extractor parts, because itself hardness of rigid coffee pads is higher, after two extraction parts compress, the degree of deformation of rigid coffee pads itself is just little, and the case peripheral wall of coffee pads itself has good sealing, aforementioned extraction parts are suitable for rigid coffee pads.But aforementioned extraction parts are then not suitable for as being used in E.S.E coffee pads.
A kind of extraction module as disclosed in the patent No. Chinese utility model patent " beverage packets in beverage extraction plant drop structure " that is ZL201220016577.8 (notification number is CN202515442U), comprise mobile extraction module and fixed extractor assembly, mobile extraction parts are made up of shell and the piston body being positioned at shell, shell is provided with inlet opening, form liquid sealing by sealing ring between piston body with outer casing inner wall to coordinate, the front end face of piston body is fixed with the meshed metallic plate of tool; Fixed extractor parts comprise the first parts, it is fixed on the front portion in support, there is in first parts the accommodating cavity being installed in coffee pads, the pushing disk of slippage before and after energy is provided with in accommodating cavity, the inner face of pushing disk has cannelure, and pushing disk has multiple axis and run through apopore, apopore is communicated with fluid hole by cannelure, the inner face of pushing disk is connected with two rear push-rods, and each rear push-rod activity is located on the rear wall of accommodating cavity; The outer face of pushing disk is fixed with two flexure strips arranged in right-angled intersection, the outer end of flexure strip outwards tilts, and the outer face of pushing disk is also fixed with screen pack, and flexure strip is positioned at outside screen pack.After forming the extraction chamber of relative closure after mobile extraction parts and fixed extractor parts close up, piston body part stretches in accommodating cavity and forms extraction chamber, by the reach of hydraulic energy driven plunger body during extraction, make between piston body and coffee pads, to form certain pressure and guarantee sealing.
Existing mobile extraction parts are rigid plane with the end face that fixed extractor parts contact with E.S.E coffee pads, after mobile extraction parts contact with E.S.E coffee pads with fixed extractor parts, move extraction parts and fixed extractor parts and E.S.E coffee pads integral plaster right poor, especially more weak to the coverage degree of E.S.E coffee pads periphery, when water under high pressure is by after E.S.E coffee pads, coffee pads pressurized bulges, but be hard contact between coffee pads and extraction parts, coffee pads is easily burst under the effect of hydraulic pressure, and the deformation space of coffee pads inside is less, fully can not extract the coffee powder in coffee pads, affect the coffee mouthfeel produced.Extract rear coffee pads in addition to be likely bonded in the rigid plane of mobile extraction parts, caused to take off bag in time.Extraction terminates rear de-bag and the reach of the pushing disk in fixed extractor machine must be relied on coffee pads could to be exited accommodating cavity, and this de-pack arrangement is complicated.
Summary of the invention
