Abstract
The invention relates to an extraction assembly of a coffer maker. The extraction assembly comprises a fixed extraction part and a movable extraction part. The fixed extraction part comprises a disc body with a liquid outlet channel. The extraction assembly is characterized in that the front end face of the disc body is provided with an inwards concave part communicated with the liquid outlet channel, a first sealing pad which is made of flexible material and can be attached to a coffee bag is arranged in the inwards concave part, a plurality of first small holes for water flow to pass are formed in the first sealing pad, and certain first elastic deformation space is formed between the rear end face of the first sealing pad and the bottom surface of the inwards concave part. The first sealing pad has high deformation capacity and can also induct the change of water pressure. The larger the water pressure is, the higher the deformation degree of the first sealing pad is, the first sealing pad always makes good contact with the coffee bag, and therefore the sealing effect is good; the first sealing pad makes flexible contact with the coffee bag, and therefore the coffee bag is not prone to being broken under the effect of water pressure, and the rebound automatic bag releasing effect is achieved.
Description
Technical field
The invention belongs to the technical field of coffee machine, relate in particular 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 relatively slippage before and after fixed extractor parts, the slippage of mobile extraction parts to after contact with fixed extractor parts between the two seal closure to form sealing, extract chamber.During extraction, the water of heating is got in extraction chamber with water pump, the flow of hot water of high pressure is crossed the beverage pack 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 a kind of is rigid coffee pads, and its body portion surrounding of coffee pads and annular edge, along making for rigid material, are densely covered with the pore that water supply stream passes through, the high strength and deformation of this coffee pads on the front/rear end of coffee pads; Another kind is flexible beverage bag, as the beverage pack of nonwoven or filter paper type, also being E.S.E coffee pads (is a kind of by ground coffee extrusion molding, similar pie, and there is a coffee pads of certain degree of hardness), wrap outside filter paper, filter paper coffee pads perimeter filter paper after hot pressing has certain hardness again.
Existing mobile extraction parts are rigid plane with the end face contacting with coffee pads in fixed extractor parts, and at least in the rigid plane of fixed extractor parts, the parts such as screen pack and flexure strip are set, 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 not suitable for as being used in E.S.E coffee pads.
As a patent No. be beverage pack in the Chinese utility model patent < < beverage extraction plant of ZL201220016577.8 (notification number is CN202515442U) drop structure > > disclosed so a kind of extraction module, comprise mobile extraction module and fixed extractor assembly, mobile extraction parts are comprised of shell and the piston body that is positioned at shell, shell is provided with inlet opening, between piston body and outer casing inner wall, by sealing ring, forming liquid sealing coordinates, 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, the accommodating cavity in the first parts with the coffee pads of being installed in, in accommodating cavity, be provided with the pushing disk of energy front and back slippage, the inner face of pushing disk has cannelure, has a plurality of apopores that axially run through on pushing disk, and 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, on the outer face of pushing disk, be fixed with two and be the flexure strip that right-angled intersection arranges, the outside perk in outer end of flexure strip, is also fixed with screen pack on the outer face of pushing disk, and flexure strip is positioned at outside screen pack.When moving after extraction parts and fixed extractor parts close up, can form behind the extraction chamber of relative closure, piston body partly stretches in accommodating cavity and formation extraction chamber, during extraction, by hydraulic energy driven plunger body, move forward, make to form certain pressure between piston body and coffee pads 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, mobile extraction parts and fixed extractor parts and E.S.E coffee pads integral plaster are 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 coffee pads is rigid contact with extracting between parts, coffee pads is easily burst under the effect of hydraulic pressure, and the deformation space of coffee pads inside is less, can not fully extract the coffee powder in coffee pads, the coffee mouthfeel that impact is produced.Extracted in addition rear coffee pads and be likely bonded in the rigid plane that moves extraction parts, caused taking off in time bag.Extraction finishes rear de-bag and must rely on the pushing disk reach in fixed extractor machine coffee pads could be exited to accommodating cavity, and this de-pack arrangement is complicated.
Summary of the invention
Technical problem to be solved by this invention is that for above-mentioned prior art present situation, to provide a kind of can be more closely and each other the extraction module of the coffee machine of flexible contact with E.S.E coffee pads laminating.
