The food agitating device
Technical field
The utility model relates to a kind of food processor, specifically is a kind of food agitating device.
Background technology
Along with the raising of people's living standard, food agitating device (for example agitator, fruit juice mixer, juice extractor, soy bean milk making machine) progresses into people's family.
Food agitating device major part is to drive the purpose that Disintegrating knife work reaches pulverizing, stirring or mixed food by power transmission shaft at present, the direct employing motor drive shaft that has between power transmission shaft and the motor is as power transmission shaft, and then needing of having is connected the purpose that reaches transmission by shaft coupling with power transmission shaft with motor drive shaft.No matter be the sort of kind of drive, all need between motor operations zone and food stir processed regions, the antiseep hermetically-sealed construction be set.
Although be provided with hermetically-sealed construction, because the influence of various factors, the phenomenon that liquid penetrates into the motor operations zone still might take place in food agitating device in use.When for example head underneath type soy bean milk making machine was cleaned in slurrying or to its base, liquid still might infiltrate head (being the motor operations zone).Brought potential safety hazard to the consumer thus, also brought quality puzzled simultaneously to manufacturer.The conventional way that addresses this problem at present is exactly further to carry out the sealing of power transmission shaft, but on the one hand but this is a self-evident hang-up to the enterprise of the household electrical appliance produced in batches, on the other hand, so still can't stop the seepage phenomenon of liquid from root.
In addition, such structure that is in transmission connection has only the function of transmission energy, does not have the function of overload protection.
The utility model content
The technical problem that the utility model solves provides a kind ofly can isolate the motor operations zone fully and stir the food agitating device that the workspace enters to prevent liquid.
For solving the problems of the technologies described above, the technical solution adopted in the utility model is:
A kind of food agitating device, it comprises pedestal, be arranged on motor in the base, be arranged on cup on the pedestal and be arranged on disintegrating mechanism in the cup, this disintegrating mechanism comprises turning cylinder and crushing knife tool, this motor comprises power output shaft, in addition: described bottom of cup is provided with separate cavities, described turning cylinder is plugged in this separate cavities, and the part shaft part that turning cylinder is arranged in this separate cavities is provided with second magnetic part, in addition, the power output shaft of described motor is provided with this second magnetic part and cooperates to form first magnetic part of magnetic shaft coupling.
As one of improving: this device comprises the supporting seat that is arranged on described bottom of cup, and this supporting seat and described bottom of cup form described separate cavities, and this supporting seat is provided with the bearing that is used to plug fixing described turning cylinder.The mode of this fixed bias circuit on the one hand can keep cup complete, on the other hand, can make the relative bottom of cup with second magnetic part of turning cylinder floating, suffered frictional force when reducing turning cylinder and rotating.
As two of improvement: between described supporting seat and the described cup for removably connecting.The mode of removably connecting can make things convenient for the user to clean separate cavities inside, also can the convenient for maintaining personnel overhaul.
As three of improvement: described bottom of cup is provided with the protuberance that is used for ccontaining described second magnetic part, and described pedestal is provided with the recess that cooperates with this protuberance, and described second magnetic part is arranged in this recess or this recess below.
As four of improvement: described turning cylinder bottom is provided with the ball that contacts with bottom of cup.
As five of improvement: described bottom of cup is provided with the strengthening part that cooperates with described ball.
Compared with prior art, the beneficial effects of the utility model are: the utility model comes indirect transfer mechanical energy by space magnetic energy, make the motor driving shaft not contact fully with the power transmission shaft of disintegrating mechanism, cup can be kept perfectly, and therefore the phenomenon that fluid seepage enters base can not take place.Simultaneously during the food processor overload, the operate as normal that can not influence motor similar traditional shaft coupling motor occurs because overload and stall or the phenomenon of burning.

Fig. 3 is the schematic diagram after Fig. 2 omits first and second magnetic parts.
The specific embodiment
Below in conjunction with accompanying drawing embodiment of the present utility model is described further.
As shown in Figure 1, the food agitating device of present embodiment comprises: pedestal 1, be arranged on motor 2 in the base, be arranged on cup 3 on the pedestal 1 and be arranged on disintegrating mechanism in the cup 3, this disintegrating mechanism comprises turning cylinder 41 and crushing knife tool 42.
As shown in Figure 2, this food agitating device is provided with supporting seat 5 in cup 3 bottoms, between itself and the cup 3 for removably connecting.This supporting seat 5 forms a separate cavities with the bottom of cup 3, and this supporting seat 5 is provided with the bearing 51 that is used to plug fixed bias circuit 41.In addition, the shaft part that turning cylinder 41 is arranged in this separate cavities is provided with second magnetic part 62, and the power output shaft 21 of motor 2 is provided with and cooperates with this second magnetic part 62 to form first magnetic part 61 of magnetic shaft coupling.In addition, turning cylinder 41 bottoms are provided with the ball 52 that contacts with cup 3 bottoms, and corresponding is that cup 3 bottoms then are provided with the strengthening part that cooperates with ball with it.
As shown in Figure 3, cup 3 bottoms are provided with the protuberance 31 that is used for ccontaining second magnetic part 62, and pedestal 1 is provided with recess 11, the second magnetic parts 62 that cooperate with this protuberance 31 and is arranged in this recess 11 or these recess 11 belows.
