Inventor has found in actual production: if (1) the first group of magnets 317 and the second group of magnets 318 directly adopt ring Shape magnet is made, then only repulsive force is without attraction between each other for the two, although suspension is more advantageous to, due to repulsive force Effect, rotary head 312 can not fits under any circumstance on the bottom of the inside of screen modules 313；(2) if first Group of magnets 317 and the second group of magnets 318 are only made of the magnet of same specification, when grinding motor 12 is operated so that rotating knife Disk 312 rotates, when the first group of magnets 317 and the second group of magnets 318 misplace, due to that can generate very strong suction between magnet Gravitation, to easily cause grinding motor 12 that can not overcome the attraction and then cause rotary head 312 stuck, even if rotating knife Disk 312 can rotate, and in dynamic state, repulsive force is alternately produced with attraction, offset so as to cause repulsive force and attraction And it is unfavorable for rotary head 312 " suspension " on the bottom of 313 inside of screen modules.

Therefore, in the present invention, the first group of magnets 317 includes multiple big magnet 3171, multiple small magnets 3172, big magnetic Iron 3171 and small magnet 3172 are spaced apart from each other one by one and are circumferentially evenly distributed with；Second group of magnets 318 includes multiple big magnet 3181, more A small magnet 3182, big magnet 3181 and small magnet 3182 are spaced apart from each other one by one and are circumferentially evenly distributed with；First group of magnets 317 and second The equal mode for cloth of the magnet of group of magnets 318 is completely the same.

Wherein, the purpose that big magnet is arranged is to realize rotary head 312 by the repulsive force relatively and between the magnet in residence Dynamic " suspension "；Small magnet is set, is on the one hand to guarantee big magnet 3171 and screen modules on rotary head 312 The small magnet 3172 on the big magnet 3181 and rotary head 312 on small magnet 3182, screen modules 313 on 313 is opposite And occupy (the big magnet 3181 on big magnet 3171 and screen modules 313 i.e. on rotary head 312, on rotary head 312 3182 mutual dislocation of small magnet on small magnet 3172 and screen modules 313) when, the big magnet 3171 on rotary head 312 Attraction is generated between the big magnet 3181 in screen modules 313 and rotary head 312 is allowed to be placed in filter screen The bottom of 313 inside of component, is on the other hand to guarantee the big magnet 3171 and screen modules 313 on rotary head 312 On small magnet 3182, the small magnet 3172 on big magnet 3181 and rotary head 312 in screen modules 313 is opposite and occupies (the big magnet 3181 on big magnet 3171 and screen modules 313 i.e. on rotary head 312, the small magnetic on rotary head 312 3182 mutual dislocation of small magnet on iron 3172 and screen modules 313) when, big magnet 3171 and mistake on rotary head 312 The small magnet on the big magnet 3181 and rotary head 312 on small magnet 3182, screen modules 313 on net-filter assembly 313 3172 generate certain mutually exclusive power, with the big magnet 3171 and screen modules 313 on partial offset rotary head 312 On big magnet 3181 between the mutual attractive force that generates, guarantee the operating for not influencing to grind motor 12.

For example, being intended to for rotary head 312 being placed in screen modules 313, the big magnet on adjustable rotating cutterhead 312 3171 and the small magnet 3182 in screen modules 313, on big magnet 3181 and rotary head 312 in screen modules 313 Small magnet 3172 it is opposite and occupy (the big magnet on big magnet 3171 and screen modules 313 i.e. on rotary head 312 3181,3182 mutual dislocation of small magnet on the small magnet 3172 and screen modules 313 on rotary head 312), such as Figure 15 institute Show, is then located at the attraction between the big magnet on rotary head 312 and screen modules 313 slightly larger than rotary head Between big magnet 3181 on 312 small magnet 3172 and screen modules 313, the big magnet 3171 of rotary head 312 and mistake The repulsive force generated between small magnet 3182 on net-filter assembly 313, moreover, in this case, rotary head 312 and filter screen The distance between component 313 is closer, and the adsorption capacity between same specification magnet is bigger, so that rotary head 312 is because being inhaled Attached and may be at static placement status, i.e., rotary head 312 can fit on the bottom of 313 inside of screen modules.

For another example, when grinding motor 12 is operated so that rotary head 312 rotates, if the big magnetic on rotary head 312 The small magnet 3172 and screen modules 313 on big magnet 3181, rotary head 312 on iron 3171 and screen modules 313 On small magnet 3182 it is opposite and occupies, as shown in figure 14, then rotary head 312 and the formation repulsion state of screen modules 313, and And in dynamic state, although repulsive force is alternately produced with attraction, existing entirety repulsive force is greater than existing entirety Attraction, so that dynamic suspension state is formed between rotary head 312 and screen modules 313, so that rotating knife Relative rotary motion can be smoothly carried out between disk 313 and fixation cutter head 314, advantageously ensure that the resulting ground coffee of grinding is thick It is thin uniform.

Further analysis, theoretically sees, the first group of magnets 317 and the second group of magnets 318 generate during the grinding process Upward repulsive force slightly larger than crushing coffee bean generate downward extruding force, advantageously ensure that rotary head 312 and filtering Suspended state is formed between the bottom of 313 inside of screen component.But under virtual condition, it is with centainly random that coffee bean, which is crushed, Property, it is extreme for, for a coffee bean, it can only be crushed in specific one point, and can not ring along entire knife Disk is crushed, and the downward extruding force at this moment generated is just concentrated at some point, and the first group of magnets 317 and the second group of magnets 318 generate upward repulsive force be then it is relatively uniform be distributed on entire cutterhead face, will lead in this way rotary head 312 production Life is centainly tilted and is contacted with the annular convex rib 3137 of 3134 inside bottom of filter screen main body, carries out generation frictional force.Therefore, this The suspended state that kind is generated because magnet is mutually exclusive is in contrast, i.e., because rotary head 312 and annular convex rib 3137 connect The sliding friction touched and generated still has during the grinding process.

But, it is assumed that without the repulsive force that the first group of magnets 317 and the second group of magnets 318 generate, crushing coffee bean is produced Raw downward extruding force will be acted on completely in 3134 inside bottom of filter screen main body, to generate very big sliding friction Power, this just gives the operating of grinding motor 12 to increase relatively large load, that is, grinding motor 12 is required to have to enough torsion ability Overcome frictional resistance and operates.Even if grinding motor 12 overcomes frictional resistance enough, still, during the grinding process, because of friction The heat of generation will will lead to device temperature raising, it will wearability and heat resistance to equipment and materials propose very huge choose War.

So, it is obvious that the first group of magnets 317 and the second group of magnets 318 during the grinding process caused by repulsive force, will Greatly improve the above problem, it may be assumed that even if rotary head 312 suspends without 100%, be also not only enough to make rotary head 312 and solid Relative rotary motion can be smoothly carried out between stationary knife disk 314, to guarantee to grind the uniformity of resulting ground coffee, but also The frictional force that rotary head 312 and screen modules 313 are generated by contact is minimized, to significantly reduce to setting The requirement of the standby wearability and heat resistance for preparing material, be conducive under the premise of guaranteeing service life of equipment reduce manufacture at This.
