The specific embodiment
Below in conjunction with the accompanying drawing in the utility model embodiment, the technical scheme in the utility model embodiment is clearly and completely described, obviously, described embodiment is only the utility model part embodiment, rather than whole embodiment.Based on the embodiment in the utility model, those of ordinary skills are not making the every other embodiment that obtains under the creative work prerequisite, all belong to the scope of the utility model protection.
As Fig. 1, Fig. 2 and shown in Figure 3, a kind of protective device for the coffee bean grinding device of the present utility model, comprise interior knife assembly and protection structure, the protection structure is arranged in interior knife assembly, interior knife assembly comprises interior cutter 1, propeller 2, interior cutter holder 3, interior cutter locking cap 4, and interior cutter locking cap 4 is arranged on interior cutter 1 upper end, and the lower surface 5 of interior cutter 1 is arranged on propeller 2, propeller 2 is provided with the mating surface 6 that is complementary with lower surface 5, and propeller 2 is arranged on interior cutter holder 3; The protection structure comprise steel ball 7, spring 8, be arranged on lower surface 5 steel ball mating holes 9, be arranged on mating surface 6 spring mounting hole 10, be arranged on the spacing plane 11 on interior cutter holder 3; steel ball 7 is arranged on steel ball mating holes 9; spring 8 is arranged in spring mounting hole 10; one end of spring 8 is arranged on spacing plane 11, and the other end of spring 8 is connected with steel ball 7.In the present embodiment, the protection structure is provided with three groups.
The diameter of steel ball 7 is slightly larger than the diametric hole of steel ball mating holes 9, and spring is equipped with in steel ball 7 back, and the active force of spring is shifted steel ball 7 in steel ball mating holes 9 onto, and steel ball 7 roughly has 1/2nd volume to be positioned at the steel ball mating holes 9 of cutter 1.During the resistance that applies greater than the internal cutter 1 of coffee bean when the tangential resistance of steel ball 7, interior cutter is rotated with propeller.When interior cutter 1 is stuck, the torsion of transmission mechanism can apply tangential force and make spring-compressed steel ball 7, and this moment, steel ball 7 will be deviate from the steel ball mating holes 9 of interior cutter 1, thereby makes interior cutter 1 break away from transmission mechanism, transmission mechanism can continue rotation, and can not cause damage to motor or transmission mechanism.
Also comprise outer cutter group 16 and coffee powder box 17, outer cutter group 16 is arranged on interior knife assembly upper end, and coffee powder box 17 is arranged on interior knife assembly lower end.Ground coffee drops in the container cavity 18 of coffee powder box 17 after grinding, then by propeller 2, ground coffee is released by ground coffee passage 19.
Operation principle:
As shown in Figure 4 and Figure 5, when mill in the situation that the normal operation, some is positioned at the steel ball mating holes 9 of cutter 1 to steel ball 7 under the active force of spring 8, when resistance that the active force of spring 8 causes mill greater than coffee bean, when the normal grinding coffee bean of mill, being fixed together with propeller 2 of interior cutter 1 rigidity
as shown in Figure 6 and Figure 7, when in coffee bean, hard foreign matter 20 being arranged, interior cutter 1 is stuck and can't rotates, this moment driving motor also in continue driving cutter holder 3 and propeller 2 rotate together, and also rotation together under the drive of propeller 2 of steel ball 7, but in this moment, cutter 1 has stopped operating, 9 pairs of steel balls of its steel ball mating holes 7 produce tangential force and steel ball 7 are promoted downwards, further make spring 8 compressions, again one the step making steel ball 7 withdraw from steel ball mating holes 9 and tangent with the lower surface 5 of interior cutter 1, only turned between propeller 2 and interior cutter 1 this moment is connected and fixes without any rigidity, interior cutter 1 breaks away from driving mechanism.Drive motors and driving mechanism can also normally move and turn when interior cutter 1 is stuck, until the user stops mill and takes out foreign matter, effectively protect the damage of whole mill.
All the other are identical with embodiment 1, and difference is, protects structure to be provided with two groups.According to different designs, the protection structure is provided with at least one group.
Adopt the beneficial effect of the technical program to be: when effectively preventing from being stuck because of cutter that foreign matter causes, transmission mechanism damages or driving motor burns, and has effectively guaranteed the service life of mill, effectively stops security incident.
By a kind of transmission of power separator, when mill worked, interior cutter can rotate with transmission mechanism, when mill is stuck, in mill, cutter breaks away from automatic and transmission mechanism, transmission mechanism can also be run well, with the damage of avoiding transmission mechanism to meet accident.
To the above-mentioned explanation of the disclosed embodiments, make this area professional and technical personnel can realize or use the utility model.Multiple modification to these embodiment will be apparent concerning those skilled in the art, and General Principle as defined herein can be in the situation that do not break away from spirit or scope of the present utility model, realization in other embodiments.Therefore, the utility model will can not be restricted to these embodiment shown in this article, but will meet the widest scope consistent with principle disclosed herein and features of novelty.
