Description
Technical field
The utility model relates to a kind of coffee machine grinder.
Background technology
Along with improving constantly of living standards of the people, coffee machine is progressively come into the family of numerous people, will use mill in coffee machine, is convenient to the coffee bean grind into powder is made coffee again.
As the patent No. is that the European patent of EP0684003B1 discloses a kind of coffee grinder, it is particularly useful for coffee machine, it comprises a conical apparatus that grinds, this taper shape grinds apparatus and can rotate around the vertical axis in grinding the axle collar, and connect by gear drive, this taper shape grinds apparatus and axially is connected with a clutch discs, this clutch discs connects a rotatable transmission device, in addition, a kind of claw coupling is provided between clutch discs and transmission device, between clutch discs and grinding apparatus, provide an overload-release clutch, limit rotatable moment of torsion, overload-release clutch includes one and contains ball, under elastic pressure, can move along clutch discs axis hole direction, cooperate with grinding apparatus bottom surface opening portion, clutch discs and gear drive partly include synthetic material and make, be characterised in that in clutch discs to have embedded metal dish, have the opening of ball hole in the above, and make to have resilient damping element between the hook of claw type connector towards the one side of grinding apparatus.The mill of this coffee machine uses in practice and shows and also have following problem:
Defectives such as 1, mill does not adopt metal cutter head broach shell, and difficulty of processing is big, and is wear-resisting, easily get rusty, and mill abrasive dust thickness is inhomogeneous, powder delivery is slow, noise is big.
2, feel trim actuator complex structure, assembling difficulty; Topmost skidding when still transshipping very easily worn and torn following support chip, has some resistances just to produce skidding a little, normal use brought have a strong impact on.
3, elasticity hitch bar assembling difficulty, no positive effect.
4, original steel ball is a solid matter on the mill, be easy to generate to dredge tight irregular phenomenon, and the location is stable bad, assembles time-consuming.
5, cutter head, broach shell are directly to be screwed on the steel ball seat that plastics do with tapping screw on the original mill, are easy to generate screw like this and skid, and cause the fixing difficulty of cutter head, and grinding effect is bad.
Comprehensively above-mentioned, also need to be further improved design.
Summary of the invention
Technical problem to be solved in the utility model is that a kind of wear-resisting, high temperature resistant, corrosion-resistant, thermal deformation is little, hardness is high, intensity is big coffee machine grinder is provided at background technology, thus make mill abrasive dust even thickness, powder delivery fast, reduce noise.
The utility model solves the problems of the technologies described above the technical scheme that is adopted: a kind of coffee machine grinder, it includes grinding head, cutter head, broach shell, transmission mechanism, grinding head is fixed on vertical rotation axle upper end in the mill, being provided with below is cutter head, cutter head is a matched in clearance with the broach shell that is arranged in the mill, also be fixed with the coffee rotating disk in the vertical rotation axle, vertical rotation axle lower end is to drive to be connected with transmission mechanism, it is characterized in that described cutter head, broach shell adopts ceramic material to make, and, cutter head is plugged and connected by alignment pin and coffee rotating disk, is supported with flexible member between cutter head and the coffee rotating disk opposite face.
Further improve, described transmission mechanism shell upper is fixed with the steel ball holder, and the steel ball holder is distributed with the lopping steel ball by annular retainer, and the coffee rotating disk rollably is arranged on above the steel ball by the last circle of annular.Use the steel ball solid matter instead the retainer structure like this, make steel ball and steel ball locations spaced clocklike, avoided phenomenon of uneven density, make its accurate positioning, easy for installation, frictional resistance minimizing.
Improve again, described vertical rotation axle adopts a long spiro nail, after passing grinding head, cutter head, coffee rotating disk, steel ball holder successively, the attaching nut, carry out axial limiting with nut and fix, and the clutch end socket connection of nut and driving mechanism together, use left-handed screw like this instead, also solve cutter head, broach shell skidding with the nut anti-looseness function, can overcome tapping screw is screwed in and is easy to generate screw thread damage on the plastics and causes the defective of skidding
Further improve; its power section motor of described driving mechanism is connected with electronic overcurrent protection device, when the motor output abnormality operating current become big as during when stall electric current be maximum, overcurrent protective device moves in the several seconds; not only current limliting but also step-down are protected motor.
Improve again, upper and lower settings is connected with the planetary gear reducing mechanism of two-stage series connection in the described driving mechanism shell, and the input of reducing gear is connected with motor, and the nut of output and long spiro nail carries out socket connection, make the transmission mechanism compact conformation, be convenient to install and peg graft.
At last, described broach shell is on cutter in the cutting ferrule, cutting ferrule also under cutter, in the embedding crane, accent amount fluted disc and crane link together, and crane is threaded in coffee meal outlet assembly outside, links together by collar and driving mechanism shell together again, can lead to the thickness that the overtravel fluted disc is adjusted abrasive flour like this, mismachining tolerance and alignment error in the elimination production process between inevitable cutter head and the broach shell.
Compared with prior art, advantage of the present utility model is: the cutter head and the broach shell that adopt ceramic material to make, and in conjunction with elastic mechanism, make cutter head assembly wear-resisting, high temperature resistant, corrosion-resistant, and thermal deformation is little, hardness is high, intensity is big, thereby makes mill abrasive dust even thickness, and powder delivery is fast, reduce noise, practicality rational in infrastructure.
