Many details are elaborated in the following description to fully understand the utility model, still, this practicality New to be different from other modes described here to implement using other, therefore, protection domain of the present utility model is simultaneously Do not limited by following public specific embodiment.

As shown in figure 1, a kind of soy bean milk making machine, including head 1 and cup 2, head 1 is placed in above cup 2, provided with electricity in head Machine 3, the bottom of head 1 is provided with blade 4, and blade 4 is fixed on the end of drive shaft 31 driven by motor 3, wherein, drive shaft 31 is For motor shaft, certainly, drive shaft can be independent rotating shaft and be driven by shaft coupling by motor.The bottom of head 1 is provided with powder Broken cover 5, without the material through hole of crossing run through on the perisporium of crushing cover 5, it is so-called cross material through hole refer to be used for material by and its hole edge For the hole of continuous closed.General, axis hole 53 is provided with the roof of crushing cover 5, is passed through for drive shaft 31.Perisporium have to The bottom of cup 2 extension multiple spoilers 51, it is so-called it is multiple refer to 2 and more than 2, generally, spoiler can set 3,4 It is individual, 5,6,7,8 etc..The lower end of spoiler 51, which is less than between blade 4, adjacent spoiler 51, forms breach 52, cup 2 Side wall is provided with raised flow-interfering bar 21, and the peak at the edge of breach 52 is higher than the minimum point of flow-interfering bar 21.

It should be noted that having a variety of differences for how to be set in crushing cover 5, the utility model in the bottom of head 1 Implementation, for example, setting downwardly projecting connector 13 in the bottom of head 1, drive shaft stretches into cup 2 through connector 13 Interior, crushing cover 5 is set on connector 13, and the bottom of connector 13 sets outwardly supporting part 14, the support powder of supporting part 14 The inwall of broken cover 5 causes crushing cover 5 to be movably installed between head 1 and supporting part 14.So so that crushing cover 5 can be with respect to machine First 1 is circumferentially rotated.

It is understood that connector 13 is except that can be the single part shown in present embodiment, it would however also be possible to employ many Individual part assembles the mode to be formed；Crushing cover 5 can also be adopted except using the uncontrolled free rotating manner of present embodiment Use miscellaneous part（It may be provided in head）Drive the mode rotated；For the utility model, branch can also be set on the driving shaft Support member, crushing cover 5 is set with the driving shaft and by supports support, passes through the introduction of present embodiment, people in the art Member is appreciated that rotating shaft sets the implementation of support member, is limited to length of the present utility model, the above is no longer tired out State.

In addition, crushing cover 5 for example can also directly be set with head 1 by the way of being fixedly connected at the top of crushing cover 5 Mounting structure is put to be attached with head 1；Downwardly projecting connector can also be equally set in the bottom of head 1, then will be crushed Cover 5 is fixedly connected with connector.Under above-mentioned mode, the horizontal range of the lower end of spoiler 51 to drive shaft axle center compared with Good is arranged to 35 to 50 millimeters, it is ensured that the relatively large aperture in the lower end of spoiler 51, relatively low noise during ensureing to crush. It is understood that by crushing cover 5 by the way of miscellaneous part driving is rotated crushing cover 5 can also be allowed to use phase with blade 4 Anti- rotation direction, in this case, the requirement of the aperture of spoiler 51 is fixedly installed similar with crushing cover 5, but can set Some larger, the horizontal range in lower end to the drive shaft axle center of spoiler 51 is preferably set to 40 to 50 millimeters.

In pulping process is crushed, blade 4, which is rotated in crushing cover 5, forms negative pressure, and the water in cup 2 and material are sucked Is crushed in crushing cover 5, partial material after the crushing of blade 4 by the outflow crushing cover 5 of breach 52, into cover outside cup In space, partial material then runs into the stop of spoiler 51 during being flowed to outside crushing cover 5 and turned back in cover, or by blade 4 separating twices, or crushing cover 5 is flowed out under the drive of liquid stream, it is important that the liquid manifold with material that the part is turned back Flow-disturbing is formed into the movement tendency different from the liquid flow path direction brought by blade 4, and then in crushing cover 5, blade 4 is improved With the contact probability of material.In addition, on the one hand the setting of breach 52 allows liquid stream smooth cover that enters from covering outer, one is formed The cycle is crushed in individual complete circulation, is on the other hand also beneficial to ensure suitable flow-disturbing intensity, it is to avoid excessive material impacting is crushed Cover 5 and bring larger noise.In addition, the edge of breach 52 is not in continuous closed, the risk of beans is not pressed from both sides completely.It is worth one It is mentioned that, because the lower end of spoiler 51 is less than blade 4, it is meant that breach 52 is at least partly to be located at the lower section of blade 4, this The material and water that the structure of sample contributes to below the place crushed face of blade 4 are concentrated to the lower section of crushing cover 5, improve entering for crushing cover 5 Expect efficiency.At the same time, the side wall of cup 2 is additionally provided with the flow-interfering bar 21 of projection so that cup 2 also functions to certain flow-disturbing function, makes Obtaining cup 2 equally has certain vibrations, it is to avoid only head 1 shakes so that formed by head 1 and cup 2 collide with Noise, and on the other hand, above-mentioned dual flow-disturbing helps vibration energy being distributed in multiple parts, reduces amplitude, and then Reduce vibrating noise.In above-mentioned circulation crushing, there is more complicated flow process from the liquid stream of the interior outflow of breach 52, specifically Say, the outflow of the tangential direction at edge of the part liquid stream along breach 52, part liquid stream directly from blade 4 be thrown out of and not with crushing Cover 5 collides, now, the interflow of two parts fluid streams, the transverse momentum with larger sensing cup sidewalls, compared with The longitudinal momentum of small sensing bottom of cup and the spinning momentum rotated in a circumferential direction, wherein transverse momentum make it that material and water can be with Quick washing generally speaking, can ignore longitudinal momentum substantially on the side wall of cup 2.And the peak at the edge of breach 52 is higher than The minimum point of flow-interfering bar 21 so that material and water with spinning momentum impact the side wall of cup 2 in the presence of transverse momentum When, rotary motion can by flow-interfering bar 21 disturbance, and be unlikely to the larger material of density by centrifugal action long-term position Outer peripheral areas inside cup 2, and reduce the efficiency that circulation is crushed.

Based on above-mentioned analysis, flow-interfering bar 21 is 3 millimeters to 6 millimeters with respect to the height of the projected side wall of cup 2, general, should Parameter is 3 millimeters, 4 millimeters, 5 millimeters or 6 millimeters.And flow-interfering bar raised height is when being less than 3 millimeters, the flow-disturbing of flow-interfering bar 21 Effect is weaker, it is impossible to meets flow-disturbing requirement well, nor beneficial to scattered vibration energy, reduces noise；Flow-interfering bar is raised Height when being more than 6 millimeters, strong circumferential flow-disturbing effect hinders the material and water below the place crushed face of blade 4 on the contrary Concentrated to the lower section of crushing cover 5, in addition, also improving difficulty of processing and cleaning difficulty.

Based on above-mentioned analysis, the liquid stream of outflow has less sensing bottom of cup from breach 52 in circulation is crushed Longitudinal momentum, therefore, the peak at the edge of breach 51 can be avoided with should higher than more than 10 millimeters of the minimum point of flow-interfering bar 21 The material and water of longitudinal momentum are when impacting 2 side wall of cup in the presence of transverse momentum, it is impossible to touch flow-interfering bar 21, so that Acted in the circumferential flow-disturbing for reducing flow-interfering bar 21.You need to add is that, flow-interfering bar can be not extend to bottom of cup, can also Extend to bottom of cup.In addition, based in above-mentioned analysis, because the lower end of spoiler 51 is less than blade 4, it is meant that breach 52 to Rare part is positioned at the lower section of blade 4, and the material and water that such structure contributes to below the place crushed face of blade 4 are to crushing The lower section of cover 5 is concentrated, and improves the powder feeding efficiency of crushing cover 5, if the lower end of spoiler 51 is less than the height of the minimum point of flow-interfering bar 21 Degree difference is more than 20 millimeters, and part liquid stream of the liquid stream under the effect of flow-interfering bar 21 in the turbulent flow turned back or be consequently formed can be rushed The lower end of spoiler 21 is hit, is unfavorable for circulation and crushes and reduction noise, therefore the lower end of selection spoiler 51 is less than flow-interfering bar 21 Within 20 millimeters of minimum point.

In the present embodiment, blade 4 sucks material below and water in crushing cover 5, from knife after the crushing of blade 4 The top of piece 4 is flowed out, and the peak at the edge of breach 52 is higher than the peak of blade 4, then is conducive to the part liquid stream smoothly to flow out powder It is broken to cover 5 and enter next round crush cycle.In addition, also part liquid stream is enters crushing cover under the drive of foregoing liquid stream, And not by the crushed face of blade 4, the part liquid stream due in inertia and crushing cover 5 pressure it is larger, and be provided with upward Longitudinal momentum and the transverse momentum to outside crushing cover, the peak at the edge of breach 52 are higher than the peak of blade 4, then are conducive to this portion Liquid stream is divided smoothly to flow out, it is to avoid to form material alluvial in crushing cover 5.Preferably, the peak at the edge of breach 52 is higher than blade 5 millimeters to 20 millimeters of peak.The peak that peak such as the edge of breach 52 is higher than blade is less than 5 millimeters, then can hinder Above-mentioned cyclic process, is unfavorable for circulation and crushes；The peak that peak such as the edge of breach 52 is higher than blade is more than 20 millimeters, then Cause breach 52 excessive, reduce the crush efficiency in crushing cover 5.In addition, the edge of breach 52 can be with curved, breach 52 The peak at edge is located at the centre on arc-shaped side edge, on the one hand, arc notch make it that the direction turned back after material impact is inconsistent, Certain flow-disturbing is formd, on the other hand, outward appearance is beautiful, is easy to user to clean, user is felt while avoiding the edge of corner angle Uncomfortable even incised wound user.

It is partly the first breach that breach 52, which is located at below the place crushed face of blade 4, and breach 52 is located at the place crushed face of blade 4 Above section is the second breach.It is to be understood that the blade of soy bean milk making machine can be divided into two kinds, a kind of is the wing part of blade In bending, it is another be wing part do not bend and at grade.For the former, due to wing bending, blade exists Crushed face during rotation is no longer just a plane, in this case, is not connected then between the first breach and the second breach Earth.Wherein, the equivalent area of passage of the first breach is more than the equivalent area of passage of the second breach, i.e. the area of the first breach is big In the area of the second breach, enter outer relative to outflow crushing cover 5 easy in crushing cover 5 equivalent to liquid stream so that crushing cover 5 Inside there is certain crushing pressure, improve the crush efficiency in crushing cover 5.Simultaneously, it is desirable to which the minimum point of flow-interfering bar 21 is located at first Between horizontal plane where the highs and lows of breach, therefore it ensure that the minimum point of the second breach is higher than flow-interfering bar first 21 minimum point, it is to avoid material and water with the longitudinal momentum are when impacting 2 side wall of cup in the presence of transverse momentum, nothing Method touches flow-interfering bar 21, so that reducing the circumferential flow-disturbing effect of flow-interfering bar 21, secondly, flow-interfering bar 21 will not also hinder knife Material and water below the place crushed face of piece 4 are concentrated to the lower section of crushing cover 5.

Preferably, it can be circumferentially rotated relative to head when crushing cover 5 works, the rotation direction of crushing cover 5 and turning for blade 4 Dynamic direction is identical, the relative rotation speed of crushing cover 5 and blade 4 is reduced, for example, 10000 revs/min of blade, crushing cover 800 Rev/min, speed discrepancy between the two is reduced to 9200 revs/min；15000 revs/min of blade, 1000 revs/min of crushing cover, two Speed discrepancy between person is reduced to 14000 revs/min.Specifically, can set to drive the motor of crushing cover；Or, By reduction gearing mechanism the rotation of the motor of blade can will be driven to pass to crushing cover；Or, crushing cover is rotatable in itself Be fixed on head bottom, by blade strip hydrodynamic stream, the rotation of crushing cover is driven under the turning effort of liquid stream.And with regard to the latter For embodiment, crushing cover can be fitted automatically when encountering the Shi Jishiyong problems such as material hardness is uncertain, inventory is uncertain Rotating speed is answered, noise is effectively reduced.And the flow-interfering bar 21 on cup 2 is set, compensate for a certain extent crushing cover 5 it is rotatable when The circumferential flow-disturbing effect brought is weakened, but be emphasized that relative to the non-rotatable situation of crushing cover, crushing cover 5 The rotatable liquid circulation speed also caused on the outside of the region of crushing cover 5 be improved, enhance the efficiency that circulation is crushed.

Further, crushed face of the crushing cover 5 where blade 4 is completely covered in the projection of vertical direction, that is, refer to from crushing Overlooked downwards directly over cover 5, no matter blade 4 goes to any angle and all can't see blade 4, it is to avoid due to turning for blade 4 Speed is higher, and draft is larger, in the case that liquid stream up has no stop, got rid of too high or even overflows, in addition also so that The pulverized cover 5 of liquid stream is turned back after stopping, and cover is interior to carry out separating twice, improves crush efficiency.

In addition, the bottom of cup 2 is provided with abrasive disk 22 with the relative position of crushing cover 5, the edge of breach 52 is in vertical direction Projection is at least partly overlapped with abrasive disk, it can be understood as, overlook downwards, can be seen through breach 52 directly over crushing cover 5 To the abrasive disk 22 of lower section.Abrasive disk 22 is set relative to the bottom protrusion of cup 2, and its upper surface can be plane, preferably Concave convex texture can be set.On the one hand, it is to avoid what bottom of cup whole installation abrasive disk was brought flows to cup subnatant The resistance concentrated below crushing cover, on the other hand, the setting of concave convex texture help to lift flow-disturbing effect, and prevent cup bottom Portion center, which is formed, crushes dead angle.

In order to further reduce the intensity of noise and head vibrations, the wing of spoiler 51 and blade 4 is using drive shaft in The heart is centrosymmetric distribution, and the quantity of spoiler 51 is identical with wing quantity.For example, wing quantity is 3, the quantity of spoiler It is similarly 3；Or, wing quantity is 4, and the quantity of spoiler is 4；Or, wing quantity is 5, the number of spoiler Measure as 5.Concrete analysis, exemplified by 3, because the wing of spoiler 51 and blade 4 is centrosymmetric centered on drive shaft Liquid stream around distribution, certain the flashy time point crushed in soy bean milk making machine, blade 4 is outside centered on the crushing center of blade Radiation, the liquid flowing speed that can be divided into 120 ° of three pieces of regions, the region and the distribution of flow direction be all it is identical or Close, because spoiler 51 is also the distribution that is centrosymmetric, and equally may be used centered on the crushing center of blade to external radiation To be divided into 120 ° of three pieces of regions, now, in the case of the liquid flow impact of three pieces of regions in the region of spoiler 51, Suffered power should be outwardly directed centered on the crushing center of blade and angle is 120 ° or close to 120 ° from each other, The size of power is same or similar simultaneously, then, what this three bursts of power offset formation from each other is then 0 with joint efforts or close 0, the dynamic balance performance of machine is improved, noise is reduced.It is appreciated that using above-mentioned principle, the quantity of spoiler can be knife The integral multiple of wing quantity.For example, wing quantity is 3, the quantity of spoiler is 6；Or, wing quantity is 4, spoiler Quantity be 8 etc..

Certainly, those skilled in the art be appreciated that above content be only preferred embodiment of the present utility model and , not for limiting practical range of the present utility model, i.e., all equivalent changes and modifications made according to the utility model are all The utility model right is covered, and no longer illustrates one by one here.
