Abstract

The utility model discloses a coffee bean grinder, including a base, a support base which is installed on the base, a feeding bowl which is installed on the support base and a shaft which penetrates the base, the support base and the feeding bowl. A grinding platform is installed in the base. A transfixion center part of the grinding platform is equipped with a mother mill. A sub-mill is installed on the tail end of the shaft and is arranged on the center of the mother mill. A positioning sleeve is arranged on the periphery of a part of the sub-mill bottom which extrudes out of the mother mill. The coffee bean grinder has the beneficial effects that: with the positioning sleeve which can effectively avoid the movement of the sub-mill in the horizontal direction during the rotation process with the shaft, the fineness of grinded coffee powder is more even; at the same time, after the movement of the sub-mill in the horizontal direction is reduced, the abrasion between the sub-mill and the mother mill is greatly reduced, and the service life of the coffee bean grinder is prolonged. In addition, the noise during the grinding is also lowered greatly.

Description

Coffee-mill

Technical field

The utility model relates to a kind of lapping device, especially a kind of grinder that is used for the ground coffee beans.

Background technology

Along with coffee more and more is subjected to people's acceptance and likes, oneself is bought coffee bean and grinds, and making oneself makes coffee behind the coffee powder has more become a kind of fashion, so the coffee-mill of small-sized household is just very welcome.Existing small-sized coffee-mill mostly comprises son mill, female mill and these three critical pieces of rotating shaft, and after coffee bean entered the space of sub-mill and female mill formation, because rotating shaft drives the rotation of son mill, coffee bean was squeezed into powder.But, problem of existing coffee-mill ubiquity, be exactly when rotating shaft drives the rotation of son mill, outside the rotation of itself that son is worn, also can carry out moving of some planes, thereby make that the coffee bean fineness of grinding out is even inadequately, and produce wearing and tearing between son mill and the female mill, cause shorten the service life of grinder.

The utility model content

The purpose of this utility model is the deficiency that moves horizontally at the easy generation that existing coffee-mill exists to provide a kind of stopping means moves horizontally problem with solution novel coffee beans grinder that adds.

The technical solution of the utility model is: a kind of coffee-mill, comprise pedestal, and be installed in the supporting base on the pedestal, be installed in the charge bowl on the supporting base, and the rotating shaft that connects pedestal, supporting base and charge bowl; The inside of pedestal is equipped with a grinding table, and the perforation central portion of grinding table is provided with female mill, and the son mill is installed in the rotating shaft tail end, and is in the central authorities of female mill, and the outer periphery that son mill bottom leans out female mill part is equipped with stop collar.

Preferably, described stop collar is an annulus, is provided with a plurality of outstanding limiting tooths at the inner edge of annulus, and this limiting tooth blocks the bottom of son mill just.

The beneficial effects of the utility model are: owing to be provided with stop collar, and stop collar can avoid the son mill moving of horizontal direction to occur effectively in the rotating shaft rotating process, and therefore the fineness of the coffee powder that grinds out is more even; Simultaneously, after the mobile minimizing of son mill horizontal direction, the wearing and tearing between son mill and the female mill must significantly reduce, and also just increase to some extent the service life of machine, and in addition, the noise during grinding also reduces greatly.

The specific embodiment

As Fig. 1 and specific embodiment of the utility model shown in Figure 3, a kind of coffee-mill comprises pedestal 28, is installed in the supporting base 13 on the pedestal 28, be installed in the charge bowl 11 on the supporting base 13, and the rotating shaft 17 that connects pedestal 28, supporting base 13 and charge bowl 11; The top of rotating shaft 17 is equipped with turning handle 3, turning handle 3 is sleeved in the rotating shaft by top cap 1, pad 2, limit body 4, rolling bearing 5, pad 6, banking stop 7, limit body 4 has a L shaped afterbody, banking stop 7 be outward flange have sawtooth ring segment, the L shaped afterbody of limit body 4 embeds in the outer rim sawtooth of banking stop 7, arbitrarily moves when rotating to avoid handle; There is a fixed mount 10 charge cup 11 inside, a supporting station 12 is arranged at the bottom of charge cup 11, fixed mount 10 is a Ω shape, its head also is sleeved in the rotating shaft 17, be provided with perforate on two legs, also have corresponding perforate on charge cup 11 and the supporting station 13 simultaneously, fixed mount 10, charge cup 11 and supporting station 12 are one by rivet 8 and pad 9 bindings, and are packed on the supporting base 13; Grinding table 15 with logical space is fixedly connected on the supporting base 13 by screw 16, female mill 14 be placed on grinding table 15 in the logical space, son mill 21 passes through the nut 18 at two ends up and down, 24 and

pad

19,20,22,23 are installed in the end of rotating shaft 17, and son mill 21 is in the central authorities of female mill 14, the bottom of son mill 21 leans out female mill 14, be equipped with a stop collar 25 in the outer periphery that leans out part, stop collar 25 is an annulus, inner edge at annulus is provided with a plurality of outstanding limiting tooths, this limiting tooth blocks the bottom of son mill 21 just, the below of stop collar 25 also is provided with a guide 26, and stop collar 25 and guide 26 are fixed on the grinding table 15 by rivet 27.

During use, coffee bean is poured in the charge cup 11, and coffee bean falls in female mill 14 immediately, and turning handle 3 then, drive 21 pairs of coffee beans of son mill by rotating shaft 17 and grind, but ground coffee powder falls in the collecting box of the pull in the pedestal 28 along the limit wall of guide 26.In the process of lapping, owing in son mill 21 spaces that stop collar 25 is limited all the time, therefore can not grind 14 and produce friction with mother.

Claims
