A soymilk maker 1000 according to an embodiment of the present invention will be described below with reference to the accompanying drawings, and the soymilk maker 1000 may prepare soymilk.

A soymilk maker 1000 according to an embodiment of the present invention may comprise a body and a grinding assembly 100. As shown in fig. 1-12, the pulverizing assembly 100 may include a pulverizing blade 1 and a pulverizing cover 2. The crushing blade 1 is provided on the motor shaft 3011 and can rotate inside the crushing cover 2 by being driven by the motor shaft 3011. The rotation of the crushing blade 1 promotes the circulation flow of the slurry inside the crushing cage 2, causing the grain particles inside the crushing cage 2 to collide with the crushing blade 1, thereby facilitating the crushing blade 1 to crush the grain particles to prepare the soybean milk.

The crushing cutter 1 comprises a cutter body 11 and a shearing wing 12 at the edge of the cutter body, and specifically, the crushing cutter 1 is fixed on the motor shaft 3011 through the cutter body 11 on one hand, and on the other hand, the crushing of grain particles is realized through the contact of the shearing wing 12 connected with the cutter body 11 and the grain particles, so as to prepare soybean milk. It can be understood that the cutter body 11 can also perform a certain crushing function on the materials in the soymilk machine 1000.

The crushing cover 2 comprises a cover body 21 rotatable relative to the body and a plurality of cover legs 22 provided at the edge of the cover body 21 and spaced apart in the circumferential direction, and a shearing blade 221 is attached to at least one of the cover legs 22. The extending directions of the shearing wings 12 and the shearing blades 221 are parallel to each other, that is, the extending direction of the shearing wings 12 and the extending direction of the shearing blades 221 are parallel to each other. Wherein the crushing blade 1 is coaxially pivotable with respect to the crushing cage 2 to form a shearing region between the shearing blades 221 and the shearing wings 12, and when the crushing blade 1 rotates, the grain particles located in the shearing region are crushed by the shearing action of the shearing wings 12, and thus, the crushing of the grain particles in the soymilk maker 1000 can be facilitated by providing the shearing region.

As shown in fig. 1 to 12, the cover body 21 has a plurality of flow guide holes 211, so as to guide the circulation of the grain inside and outside the grinding hood 2, and increase the probability that the grain enters the shearing region and is sheared by the shearing wings 12, thereby improving the crushing effect and the crushing efficiency of the soymilk machine 1000, and preparing soymilk with fine taste. Optionally, there is at least one baffle hole 211 between two circumferentially adjacent legs 22 of the shroud 21.

At least one of the cover legs 22 has an introduction portion 222 configured to introduce the material outside the cover body 21 into the cutting region, and specifically, when the crushing blade 1 rotates to drive the slurry to self-circulate, the grain particles near the crushing cover 2 are simultaneously subjected to the centripetal force toward the center of the crushing cover 2 and the centrifugal force along the tangential direction of the rotating track of the crushing blade 1, so that the material near the crushing cover 2 can be introduced into the cutting region and crushed in the cutting region to a certain extent by the introduction portion 222, thereby improving the crushing effect and the crushing efficiency of the soymilk maker 1000 and preparing soymilk with fine mouthfeel.

An included angle α between the normal line of the introducing part 222 and the tangent line of the introducing part 222 is 3-87 degrees, wherein on the horizontal projection of the crushing cover 2, a connecting line between the rotation center of the crushing knife 1 and the outermost end point of the introducing part 222 is a introducing reference connecting line, and the tangent line of the introducing part 222 is perpendicular to the introducing reference connecting line, the structure of the crushing assembly 100 is optimized by adjusting the range of the included angle α, so that the introducing part 222 introduces the grain particles into the crushing cover 2, the crushing of the grain particles by the crushing knife 1 is facilitated, and the crushing effect of the soymilk machine 1000 is improved to a certain extent.

According to the soybean milk machine 1000 of the embodiment of the invention, the introduction part 222 is arranged on the crushing cover 2, and the included angle α between the normal line of the introduction part 222 and the tangent line of the introduction part 222 is in the range of 3-87 degrees, so that the introduction part 222 can introduce the grain particles into the crushing cover 2, the crushing of the grain particles by the crushing knife 1 is facilitated, the crushing effect of the soybean milk machine 1000 is improved to a certain extent, and the soybean milk without dregs and filtration is prepared.

Specifically, for example, when α is 0 degrees, as shown in fig. 11(a), the normal line of the inlet 222 coincides with the tangent line of the inlet 222, and when the grain particles are thrown out of the hood 2 by centrifugal force and cannot enter the cutting area inside the hood 2, the cutting effect is poor, when α is further increased, as shown in fig. 11(b), the feeding gap is large, so that the grain particles enter the hood 2, and the grain particles inside the hood 2 are not easily thrown out, so that the grain particles enter the cutting area to be cut, and the cutting effect is good, when the value of α is further increased to 25 degrees, as shown in fig. 11(b), the feeding gap is large, so that the grain particles enter the hood 2, and when the value of α is further increased to 65 degrees, although the grain particles introduced into the hood 2, the effective cutting area between the cutting wings 12 and the cutting wings 221 is small, so that the cutting effect becomes small, when the angle between the cutting angle of the tangent line of the inlet 222 and the cutting area is increased, as shown in fig. 11(c), the angle between the tangent line of the grinding area is not good, as shown by the tangent line of the cutting area of 387, and the grinding area of the inlet 222, so that the grinding area is not good, when the angle of the grinding area of the inlet 222 is increased, as shown in fig. 11, the grinding area, as shown in fig. 5, the grinding area, as the grinding area, the inlet 222, as shown in fig. 11, the grinding area is not good, as the grinding area, as shown in fig. 11, the grinding area, as shown in fig. 5, the angle is not good, when the grinding area, as the grinding area, the angle is not good, as the angle of the grinding area.

According to some embodiments of the present invention, the other side surface of the at least one shroud leg 22 in the circumferential direction may be configured as a blocking portion 223 for forcing the material into the shearing area, and the blocking portion 223 may not only force the material into the shearing area, but also block the grain particles inside the pulverizing hood 2 from escaping out of the pulverizing hood 2 due to the centrifugal action of the pulverizing knife 1, thereby ensuring that the grain particles are repeatedly introduced into the shearing area inside the pulverizing hood 2.

The introduction part 222 and the blocking part 223 are not parallel, that is, the included angle between the blocking part 223 and the introduction part 222 is between 0 and 180 degrees, so that the action areas of the introduction part 222 and the blocking part 223 can be increased to a certain extent, and the grain particles in a larger range around the outer side of the pulverizing cover 2 can be introduced into the shearing area to be pulverized by the pulverizing knife 1, thereby improving the pulverizing effect and the pulverizing efficiency.

According to some embodiments of the present invention, as shown in fig. 1, the shroud legs 22 include 4 evenly spaced apart in the circumferential direction, that is, the number of the shroud legs evenly spaced apart in the circumferential direction of the shroud body 21 is 4.

In some embodiments of the present invention, as shown in fig. 2-10, the cross-sectional area of the cover 21 gradually increases from the distance from the legs 22 to the direction toward the legs 22, that is, the cross-sectional area of the cover 21 becomes larger and larger in the direction toward the legs 22 until it is connected to the legs 22. Further, the cover body 21 is formed in a spherical crown shape or a truncated cone shape, whereby it is possible to facilitate not only the mounting of the crushing cover 2 but also the increase of the volume of the crushing cover 2, of course, the present invention is not limited thereto, and the cover body 21 may be formed in other shapes.

Furthermore, an annular flow gathering ring 23 is arranged between the cover body 21 and the cover legs 22, the flow gathering ring 23 can promote the grain particles to gather into the crushing cover 2, and meanwhile, the grain particles in the crushing cover 2 can be ensured not to run out of the crushing cover 2 to a certain extent, so that the grain particles enter the shearing area to be crushed to refine the grain particles, and the soybean milk with fine outlet feeling is prepared.

Specifically, the cross-sectional shape of the flow focusing ring 23 is formed in a straight line, an arc line, or a broken line shape, however, it will be understood by those skilled in the art that the flow focusing ring 23 may be formed in other shapes.

Furthermore, as shown in fig. 3 and 4, the flow gathering ring 23 and/or the shroud leg 22 are formed with the spoiler rib 231 and/or the spoiler notch 232, that is, one of the spoiler rib 231 and the spoiler notch 232 may be formed on the flow gathering ring 23 and/or the shroud leg 22, and of course, both the spoiler rib 231 and the spoiler notch 232 may be formed on the flow gathering ring 23 and/or the shroud leg 22. When the crushing knife 1 rotates, the turbulence ribs 231 and/or the turbulence notches 232 arranged on the flow gathering ring 23 and/or the cover legs 22 can disturb the water flow circulation of the crushing cover 2, so that the grain particles are forced to move towards the shearing area in the crushing cover 2, and the crushing knife 1 crushes the grain particles, thereby improving the crushing effect, refining the grain particles and preparing the soybean milk with fine outlet feeling.

In a further embodiment of the present invention, as shown in fig. 5, the cover 21 is provided with a spoiler rib 231 spaced apart from the leg 22, for example, the spoiler rib 231 is spaced apart from the leg 22 on the cover. The vortex rib 231 that sets up with shank 22 spaced apart on the cover body 21 can be when smashing the rotatory rivers circulation around the cover 2 of disorderly smashing of sword 1, forces cereal granule to move towards the shearing area in smashing the cover 2 to make and smash sword 1 with it and smash, thereby improve crushing subassembly 100's crushing effect, refine cereal granule, prepare the exquisite soybean milk of sense of export.

According to some embodiments of the present invention, the cutting blade 221 is connected to one end of the hood leg 22 and the other end extends toward the crushing blade 1, so that a cutting region is formed between the cutting blade 221 and the cutting wings 12 of the crushing blade 1, so that the grain particles are crushed by the cutting wings 12 in the cutting region, the grain particles are refined, the crushing effect is improved, and thus the soymilk with fine mouthfeel is prepared.

The extending direction of the cutting blades 221 is parallel to the rotation plane of the pulverizing cutter 1, for example, as shown in fig. 7 and 9, when the cutting blades 221 extend toward the central axis of the pulverizing casing 2, they are parallel to the rotation plane of the pulverizing cutter 1, so that axial shearing can be formed between the cutting blades 221 and the pulverizing cutter 1, thereby facilitating the axial shearing of the grain particles in the pulverizing casing 2 to pulverize the grain particles.

Further, the surface of the shearing wing 12 close to the shearing blade 221 is parallel to the extending direction of the shearing blade 221, that is, the surface of the shearing wing 12 opposite to the shearing blade 221 is parallel to the extending direction of the shearing blade 221, so that an axial shearing action is formed between the shearing wing 12 and the shearing blade 221, so as to axially shear the grain particles in the shearing region, improve the crushing effect, and prepare the soybean milk with fine taste.

In a further embodiment of the present invention, the cutting blades 221 extend in a direction perpendicular to the rotation plane of the crushing blade 1, and the cutting wings 12 are disposed perpendicular to the blade body 11, thereby facilitating radial cutting of the grain particles in the cutting region to crush the grain particles, and preparing the residue-free and filtration-free soybean milk.

According to some embodiments of the present invention, the cutting blade 221 is connected to one end of the mantle leg 22 and the other end thereof defines a gap with the mantle leg 22, the length of the portion of the cutting wing 12 extending into the gap is L, the maximum radius of rotation of the crushing blade 1 is R, and L and R are satisfied: 1/25 is less than or equal to L/R is less than or equal to 9/10. The size of the cutting area is adjusted by adjusting the sizes of L and R. It can be understood that, under the condition that the rotating speed of the crushing knife 1 is not changed, the larger the shearing area is, the better the crushing effect is, therefore, on the premise of ensuring the rotating speed of the crushing knife 1, the shearing area is increased as much as possible, so that the crushing effect of the crushing assembly 100 is improved, and the soybean milk with fine and smooth outlet feeling is prepared.

Specifically, when L/R is 0, as shown in fig. 7(a), L is 0, the cutting blade 12 does not extend into the gap, and at this time, a cutting region cannot be formed between the cutting blade 221 and the cutting blade 12, so that a cutting action cannot be formed between the cutting blade 221 and the cutting blade 12, and at this time, the grinding effect of the soymilk grinder 1000 cannot be effectively improved. When L/R is 4/25 (for example, in this case, L is 8mm, and R is 50mm), as shown in fig. 7(b), the cutting wings 12 extend into the appropriate positions of the gap, and a cutting action is formed between the cutting blades 221 and the cutting wings 12, so that the pulverizing effect of the soymilk grinder 1000 can be improved to some extent. When L/R is 9/10 (for example, when L is 45mm, R is 50mm), although the shearing area formed by the shearing wings 12 and the shearing blades 221 is large, as shown in fig. 7(c), the radius of the crushing blade 1 is large at this time, which causes the load of the motor 301 to be too large, thereby directly affecting the rotation speed of the crushing blade 1, and the crushing effect of the soymilk grinder 1000 is affected to some extent by the rotation speed of the crushing blade 1 at this time. Alternatively, 2/25 ≦ L/R ≦ 2/3. Further optionally, 4/25 ≦ L/R ≦ 2/5.

According to some embodiments of the present invention, as shown in FIGS. 7 and 8, the distance between the end of the shearing wings 12 and the inner end of the gap is X, wherein X ≧ 1mm, whereby it is possible to facilitate the entry of grain particles of respective particle sizes into the gap between the end of the shearing wings 12 and the inner end of the gap to cause the end of the shearing wings 12 to shear them. Further, X is more than or equal to 3 mm. More preferably, X is more than or equal to 5mm and less than or equal to 15 mm.

In some embodiments of the invention, the maximum diameter of the crushing mantle 2 is D, the maximum rotation diameter of the crushing knife 1 is D, D and D are such that: D/D is not less than 1/4 and not more than 1, and the size of the shearing area is convenient to adjust by adjusting the sizes of D and D, so that the crushing effect of the soybean milk machine 1000 is improved, and the soybean milk with fine mouthfeel is prepared.

Specifically, when D/D is 1/4, specifically, taking the maximum diameter of the pulverizing hood 2 of the prior art as 120mm and the maximum rotation diameter of the pulverizing knife 1 as 30mm as an example for illustration, as shown in fig. 9(a), since the pulverizing hood 2 is too large, the pulverizing knife 1 is too small, and the limited pulverizing area formed by the pulverizing hood 2 and the pulverizing knife 1 is too small, the pulverizing efficiency of the pulverizing assembly 100 is low. When D/D is 4/7 (e.g., D is 70mm, D is 40mm), as shown in fig. 9(b), the ratio of the maximum rotating diameter of the crushing blade 1 to the maximum diameter of the crushing hood 2 is moderate, the crushing blade 1 is relatively balanced with respect to the crushing hood 2, and thus the crushing efficiency of the crushing assembly 100 is high. However, if D is not changed, if D is further increased, for example, D is 70mm and D is 60mm, then the crushing blade 1 is too large relative to the crushing cover 2, the load in the crushing cover 2 is large, the load of the motor 301 is large, the rotation speed of the crushing blade 1 is relatively low, the crushing efficiency is relatively low, and the crushing effect is influenced to some extent. When D/D is 1, as shown in fig. 9(c), the crushing blade 1 forms a single-side shearing, which is not beneficial to crushing the grain particles, and at this time, the soybean milk machine 1000 has a low crushing efficiency and a relatively poor crushing effect. Alternatively, the maximum rotation diameter D of the crushing blade 1 and the maximum diameter D of the crushing hood 2 may also satisfy: D/D is not less than 1/3 and not more than 6/7, thereby further improving the crushing effect of the soymilk machine 1000. More preferably, D/D is not less than 4/7 and not more than 5/6.

According to some embodiments of the present invention, as shown in FIG. 9, the gap between the extending direction of the cutting blade 221 and the extending direction of the cutting wing 12 is Y, wherein Y ≧ 0.5mm, that is, the perpendicular distance between the extending direction of the cutting blade 221 and the extending direction of the cutting wing 12 is Y, and Y ≧ 0.5. Further, Y is more than or equal to 1 mm. More preferably, Y is more than or equal to 1.5mm and less than or equal to 4 mm.

According to some embodiments of the present invention, the plurality of shearing blades 221 are asymmetric with respect to the center of the pulverizing casing 2. Further, one side surface of the plurality of shearing blades 221 facing the crushing cutter 1 is located on different horizontal planes, so that different shearing areas are formed between the plurality of shearing blades 221 and the corresponding shearing wings 12 in the direction perpendicular to the horizontal planes, the three-dimensional shearing of grain particles is realized, the crushing effect is improved, and the grain particles are refined.

Alternatively, as shown in fig. 13 and 14, the height difference between the horizontal planes of the adjacent cutting blades 221 is H, when H is too large, the gap between the cutting region formed between one or more cutting blades 221 and the cutting wing 12 is large, which is not beneficial to the crushing of the grain particles, when H is too small, the gap between the cutting region formed between the cutting blades 221 and the cutting wing 12 is small, the three-dimensional crushing and cutting effect is not obvious, and in sum, the height difference between the horizontal planes of the adjacent cutting blades 221 is selected as: h is less than or equal to 1 mm. Further optionally, H ≦ 0.5 mm. Furthermore, H is more than or equal to 0.1mm and less than or equal to 0.3 mm.

Alternatively, the radially outer ends of the plurality of cutting blades 221 are located on different circumferential surfaces, that is, the distances between the radially outer ends of the plurality of cutting blades 221 and the center of the pulverizing casing 2 are not equal.

According to some embodiments of the present invention, as shown in FIGS. 10 and 16-17, the direction of extension of the shear blades 221 has an angle γ with respect to the horizontal, as shown in FIGS. 10 and 16-17 and 26-27, where γ ≧ 0 degrees. Thus, the cutting blades 221 may extend upward or downward with respect to the horizontal plane. Specifically, when the extension direction of the cutting blades 221 forms an angle γ with respect to the horizontal plane, since the extension direction of the cutting wings 12 and the extension direction of the cutting blades 221 are parallel to each other, the extension direction of the cutting wings 12 also forms an angle γ with respect to the horizontal plane, and the cutting action between the cutting wings 12 and the cutting blades 221 forms a three-dimensional shear, thereby increasing the pulverizing effect of the pulverizing assembly 100 and preparing the residue-free and filtration-free soybean milk.

Further, gamma is more than or equal to 5 degrees, so that the three-dimensional shearing effect between the shearing wings 12 and the shearing blades 221 is further enhanced, the grain particles are conveniently subjected to three-dimensional shearing, the crushing effect of the crushing assembly 100 is further improved, and the dreg-free and filtration-free soybean milk is prepared.

Specifically, when the angle γ of the extending direction of the cutting blade 221 with respect to the horizontal plane is very large, the crushing blade 1 stirs the slurry in the crushing cover 2, at this time, although the turbulence effect is increased, the linear velocity of the cutting blade 12 is reduced, thereby reducing the crushing effect, and at the same time, the large value γ makes the load of the motor 301 unbalanced, and generates a cavity, resulting in a large noise of the soymilk maker 1000. When γ is too small, the three-dimensional pulverizing effect formed by the shearing region between the shearing blades 221 and the shearing wings 12 in the pulverizing hood 2 is insignificant, and the pulverizing effect is poor. In summary, optionally, γ is 5 ≦ γ ≦ 10 degrees, thereby further increasing the three-dimensional pulverizing effect of the pulverizing assembly 100.

According to some embodiments of the present invention, as shown in fig. 13, the cutting blades 221 are formed in a step shape having one end connected to the leg 22 and the other end extending toward the crushing blade 1, whereby the turbulence effect of the cutting blades 221 on the slurry in the crushing hood 2 can be increased to some extent, so that more grains enter into the cutting region to participate in the crushing, thereby improving the crushing effect and preparing the residue-free and filtration-free soybean milk.

In some embodiments of the present invention, as shown in fig. 18, the cutting blade 221 is parallel to the rotation plane of the crushing blade 1, and the free end of the cutting blade 221 extends out of the extension 2211 away from the crushing blade 1, and the extension 2211 can increase the turbulence effect of the slurry in the crushing cover 2, so that more grains enter the cutting area to participate in crushing, thereby increasing the crushing effect.

According to some embodiments of the present invention, as shown in fig. 15, the cutting blade 221 extends in a vertical direction, the cutting blade 221 is parallel to a portion of the hood leg 22 and has one end connected to the hood leg 22, wherein the cutting wing 12 extends between the hood leg 22 and the cutting blade 221, whereby a radial cutting action is formed between the cutting blade 221 and the cutting wing 12, thereby facilitating radial cutting of the grain particles in the cutting region to pulverize the grain particles and prepare the residue-free and filtration-free soybean milk.

In some alternative embodiments of the present invention, as shown in fig. 19, the shearing blades 221 are parallel to the rotation plane of the crushing blade 1, and the middle part of the shearing blades 221 is far away from the projections 2212 of the crushing blade 1, the projections 2212 can increase the turbulence effect of the slurry in the crushing cover 2, so that more grains enter into the shearing area to participate in crushing, thereby improving the crushing effect.

According to some embodiments of the present invention, as shown in fig. 20, the cutting blade 221 is parallel to the rotation plane of the crushing blade 1, the cutting blade 221 has a through hole, and a protrusion 2213 far from the crushing blade 1 is connected to the through hole, the protrusion 2213 can increase the turbulence effect of the slurry in the crushing cover 2, so that more grains enter the cutting area to participate in crushing, thereby improving the crushing effect.

According to some embodiments of the present invention, an included angle β between the blocking portion 223 and a tangent of the blocking portion 223 is in a range of 3-90 degrees, wherein on a horizontal projection of the pulverizing hood 2, a tangent taken from an extreme point of the outermost end of the blocking portion 223 to a rotation trajectory circle of the pulverizing knife 1 is the tangent of the blocking portion 223, and different β values have different effects on the pulverizing effect of the soymilk machine 1000.

Specifically, for example, when β is 0 degrees, as shown in fig. 12(a), the stopper 223 coincides with the tangent of the stopper 223, and at this time, the stopper 223 cannot effectively prevent the grain from being thrown out of the hood 2 by the centrifugal force, and the pulverizing effect is poor, when β is 5 degrees, as shown in fig. 12(b), the stopper 223 can block the grain into the edge of the shearing region, and the effective shearing region is small, and the pulverizing effect is relatively poor, when the β value is further increased to 60 degrees, as shown in fig. 12(c), the stopper 223 can block the grain into the shearing region, and the pulverizing effect is good, however, when the β value is further increased to 97 degrees, as shown in fig. 12(d), the stopper 223 cannot block the grain into the hood 2, and the pulverizing efficiency is low, and the pulverizing effect is poor, and therefore, the angle β between the stopper 223 and the tangent of the stopper 223 may be further selected to be 5 to 82 degrees, thereby further optimizing the structure of the stopper 223 to further facilitate the entrance of the grain into the hood 2, and the angle β between the grain is further optimized.

As shown in fig. 13-23 and 32, the body may include a body 200 and a handpiece 300, according to some embodiments of the invention. Wherein, the top of the machine body 200 is open and defines a processing chamber 201, the crushing assembly 100 is arranged in the processing chamber 201, and a user can put grains into the processing chamber 201 from the open top of the machine body 200 to be crushed by the crushing assembly 100, so as to prepare soybean milk.

The handpiece 300 is disposed on the machine body 200, and the motor 301 is disposed in the handpiece 300, and the motor shaft 3011 of the motor 301 extends downward, specifically, the handpiece 300 can be disposed on the open top of the machine body 200 to close or open the machine body 200, and the motor shaft 3011 of the motor 301 extends downward into the machine body 200. The crushing blade 1 is rotated by the motor 301, and the crushing hood 2 is connected to the head 300, and the motor shaft 3011 is driven by the motor 301 to rotate the crushing blade 1, so as to crush the grain particles in the crushing hood 2, thereby preparing the soybean milk.

According to some embodiments of the present invention, the soymilk grinder 1000 further comprises a positioning cylinder 700, the positioning cylinder 700 is arranged in the machine body 200 and sleeved outside the motor shaft 3011, wherein the grinding cap 2 further comprises a mounting portion 24 connected to the cover body 21, the mounting portion 24 is arranged outside the positioning cylinder 700, and the positioning cylinder 700 is arranged outside the motor shaft 3011 of the soymilk grinder 1000, so that the grinding cap 2 is conveniently mounted outside the positioning cylinder 700 through the mounting portion 24 to realize the fixed mounting of the grinding cap 2. The lower portion of the head 300 is further provided with a lower cover for firmly fixing the pulverizing cover 2 to the head 300.

Further, the mounting portion 24 is pivotally sleeved outside the positioning cylinder 700 through the sleeve 400, and thus, the crushing cover 2 is pivotally sleeved outside the positioning cylinder 700 through the sleeve 400. Specifically, when the motor shaft 3011 drives the crushing blade 1 to rotate, the crushing cover 2 also rotates around the axis of the motor shaft 3011 in the same direction as the crushing blade 1, and it can be understood that the crushing blade 1 and the crushing cover 2 rotate at different speeds. Therefore, differential shearing is formed between the shearing blades 221 of the crushing cover 2 and the shearing wings 12 of the crushing blades 1 to crush grain particles in the crushing cover 2, the crushing effect is improved, the slag-free and filtration-free effect is achieved, and the crushing cover 2 stirs slurry in the rotating process, so that bottom pasting is prevented to a certain extent.

According to some embodiments of the present invention, as shown in fig. 10 and 13, and fig. 16 to 17, the maximum rotation diameter of the crushing blade 1 is d, the diameters of the processing chamber 201 at the corresponding positions to the rotation plane of the crushing blade 1 are Dm, and d and Dm satisfy the following conditions: d/Dm is not less than 3/18 and not more than 3/4, and different d/Dm values have different influences on the crushing effect of the soybean milk machine 1000.

Specifically, if the maximum rotation diameter d of the crushing blade 1 is small and the diameter Dm of the processing chamber 201 at the position corresponding to the rotation plane of the crushing blade 1 is large, the ineffective crushing area in the soymilk machine 1000 is large, and the crushing effect of the soymilk machine 1000 is poor. If the maximum rotating diameter d of the crushing blade 1 is large and the diameter Dm of the processing chamber 201 at the position corresponding to the rotating plane of the crushing blade 1 is small, the load of the motor 301 becomes large due to the large crushing blade 1, the rotating speed of the crushing blade 1 is affected, and the crushing effect is relatively poor. Further, the relationship between the maximum rotation diameter d of the crushing blade 1 and the diameter Dm of the processing chamber 201 at the corresponding position to the rotation plane of the crushing blade 1 may be selected as: d/Dm is not less than 1/4 and not more than 7/13, so that the structure of the soymilk machine 1000 is further optimized, and the crushing effect of the soymilk machine 1000 is improved. More preferably, the relationship between the maximum rotation diameter d of the crushing blade 1 and the diameter Dm of the processing chamber 201 at the corresponding position to the rotation plane of the crushing blade 1 may also be: d/Dm is not less than 4/15 and not more than 6/13, so that the structure of the soybean milk machine 1000 is optimized to a greater extent, and the crushing effect is improved.

According to some embodiments of the present invention, as shown in fig. 21-22 and 32, the treatment chamber 201 has a constriction 800 at a position corresponding to the crushing assembly 100, and the maximum diameter of the constriction 800 is smaller than the diameter of the treatment chamber 201 at other positions to form a small space, thereby not only facilitating the accumulation of grain particles in the constriction 800, but also enabling the small space shearing between the shearing blades 221 and the shearing wings 12 in the constriction 800, and when the crushing blade 1 rotates, a negative pressure is formed in the crushing hood 2, thereby facilitating the grain particles in the slurry to enter the crushing hood 2 to facilitate the crushing of the crushing blade 1, and improving the crushing effect.

Further, the minimum radial clearance between the constriction 800 and the mill housing 2 is M, however, it is understood that the magnitude of M has a certain influence on the milling effect. For example, when the value M is large, the ineffective grinding area between the grinding cap 2 and the constriction 800 is large, and the small space between the cutting blade 221 and the cutting wing 12 cannot be cut, so that the grinding efficiency is low, the grinding effect is not good, and the noise of the soymilk grinder 1000 is large at this time, which affects the life of the user. When the M value is very small, the grain particles are easily clamped between the contraction part 800 and the crushing cover 2, so that the circulation of slurry inside and outside the crushing cover 2 is not smooth, the crushing efficiency is low, and the crushing effect is poor. Alternatively, the minimum radial clearance between the constriction 800 and the comminution hood 2 is: m is larger than or equal to 5mm, so that the structure of the soymilk machine 1000 is optimized to a certain extent to form small-space shearing in the soymilk machine 1000, and the crushing efficiency and the crushing effect are improved.

Further, the radial minimum clearance between the constriction 800 and the comminution hood 2 can also be: m is larger than or equal to 8mm, so that the structure of the soymilk machine 1000 is further optimized, small-space shearing is formed in the soymilk machine 1000, and the crushing efficiency and the crushing effect are improved. Still further, the minimum radial clearance between the constriction 800 and the comminution hood 2 can also be satisfied: m is more than or equal to 10mm and less than or equal to 20 mm.

In some embodiments of the present invention, the maximum diameter of the constriction 800 is D1, and the size of the maximum diameter of the constriction 800 is one of the critical parameters for the impact of the comminution effect. For example, when D1 is large, the ineffective grinding area in the soymilk maker 1000 is large, resulting in poor grinding effect of the soymilk maker 1000. When D1 is very small, it is not only inconvenient to assemble the heating structure on the body 200, but also it is easy to cause bottom-sticking due to high heat load at the bottom of the body 200. The maximum diameter of the constriction 800 may be selected as: d1 is not more than 130mm, so that the structure of the soymilk machine 1000 is optimized to a certain extent to form small-space shearing in the soymilk machine 1000 and improve the crushing effect.

Still further, the maximum diameter of the constriction 800 may also be: d1 is less than or equal to 110mm, so that the structure of the soymilk machine 1000 is further optimized to form small-space shearing in the soymilk machine 1000 and improve the crushing effect. Still further, the maximum diameter range of the constriction 800 may also be: d1 is more than or equal to 80mm and less than or equal to 100 mm.

According to some embodiments of the present invention, as shown in fig. 18 to 20, the distance between the crushing blade 1 and the bottom wall of the processing chamber 201 is S, and when S is very small, the load of stirring the slurry when the crushing blade 1 rotates is large, and the downward pressure of the crushing blade 1 is large, so that the temperature rise of the motor 301 is high, and at the same time, the rotation speed of the crushing blade 1 is low, and the crushing effect is poor. When S is very large, the load of stirring the slurry is small when the crushing knife 1 rotates, the downward pressure of the crushing knife 1 is small, and a vortex is easily generated in the soybean milk machine 1000, so that the noise of the soybean milk machine 1000 is large, the crushing efficiency is reduced, and the crushing effect is poor. Therefore, the distance between the crushing blade 1 and the bottom wall of the processing chamber 201 can be selected as follows: s is more than or equal to 8 mm. Further, S is larger than or equal to 10mm, so that the structure of the soybean milk machine 1000 is further optimized, and the crushing effect is improved. Furthermore, S is more than or equal to 15mm and less than or equal to 40 mm.

According to some embodiments of the present invention, the lowermost end of the pulverizing cover 2 is not higher than the lowermost end of the motor shaft 3011, that is, the lowermost end of the pulverizing cover 2 is located below the lowermost end of the motor shaft 3011, or is flush with the lowermost end of the motor shaft 3011, so that the handpiece 300 can stand on a table when the handpiece 300 is taken off from the machine body 200, which not only facilitates the placement of the handpiece 300, but also protects the table from being scratched by the pulverizing blade 1 and simultaneously prevents the pulverizing blade 1 from being damaged.

Further, as shown in FIGS. 18-20, the height difference between the lowermost end of the pulverizing cover 2 and the lowermost end of the motor shaft 3011 is P, wherein P is greater than or equal to 0mm, thereby facilitating the placement of the handpiece 300 and avoiding the unstable standing of the handpiece 300 due to the lowermost end of the motor shaft 3011 protruding out of the lowermost end of the pulverizing cover 2. Further, the height difference between the lowermost end of the crush can 2 and the lowermost end of the motor shaft 3011: p is larger than or equal to 1mm, so that the structure of the soymilk machine 1000 is further optimized to be beneficial to the placement of the machine head 300. And further, P is more than or equal to 2mm and less than or equal to 6mm, so that the placement of the machine head 300 is facilitated, and the poor appearance of the crushing cover 2 and the waste of materials in the process of manufacturing the crushing cover 2 caused by a large P value are avoided to a certain extent.

Crushing unit 100 establishes in processing chamber 201, and crushing sword 1 is rotatory by the drive of motor 301, and crushing cover 2 is connected cup 600 bottom and cover leg 22 and is stretched out upwards, through the rotation of motor 301 drive motor shaft 3011 in order to drive crushing sword 1, smashes the cereal granule in crushing cover 2 to prepare the soybean milk.

According to some embodiments of the present invention, the soymilk grinder 1000 further comprises a positioning cylinder 700, the positioning cylinder 700 is arranged in the cup body 600 and sleeved outside the motor shaft 3011, wherein the grinding cap 2 further comprises an installation part 24 connected to the cover body 21, the installation part 24 is arranged outside the positioning cylinder 700, and the positioning cylinder 700 is arranged outside the motor shaft 3011 of the soymilk grinder 1000, so that the grinding cap 2 is conveniently installed outside the positioning cylinder 700 through the installation part 24 to realize the fixed installation of the grinding cap 2.

Further, the mounting portion 24 is pivotally sleeved outside the positioning cylinder 700 through the sleeve 400, and thus, the crushing cover 2 is pivotally sleeved outside the positioning cylinder 700 through the sleeve 400. Specifically, when the motor shaft 3011 drives the crushing blade 1 to rotate, the crushing cover 2 also rotates around the axis of the motor shaft 3011 in the same direction as the crushing blade 1, and it can be understood that the crushing blade 1 and the crushing cover 2 rotate at different speeds. Therefore, differential shearing is formed between the shearing blades 221 of the crushing cover 2 and the shearing wings 12 of the crushing blades 1 to crush the grain particles in the crushing cover 2, the crushing effect is improved, the slag-free and filtration-free effect is achieved, and the crushing cover 2 stirs the slurry to prevent bottom pasting to a certain extent.

According to some embodiments of the present invention, the maximum rotation diameter of the crushing blade 1 is d, and the diameters of the processing chamber 201 at the corresponding positions to the rotation plane of the crushing blade 1 are Dm, and d and Dm satisfy the following conditions: d/Dm is not less than 3/18 and not more than 3/4, and different d/Dm values have different influences on the crushing effect of the soybean milk machine 1000.

According to some embodiments of the present invention, as shown in fig. 28-29 and 31, the treatment chamber 201 has a constriction 800 at a position corresponding to the crushing assembly 100, and the maximum diameter of the constriction 800 is smaller than the diameter of the treatment chamber 201 at other positions to form a small space, thereby not only facilitating the accumulation of grain particles in the constriction 800, but also enabling the small space shearing between the shearing blades 221 and the shearing wings 12 in the constriction 800, and when the crushing blade 1 rotates, a negative pressure is formed in the crushing hood 2, thereby facilitating the grain particles in the slurry to enter the crushing hood 2 to facilitate the crushing of the crushing blade 1, and improving the crushing effect.

In some embodiments of the present invention, the maximum diameter of the constriction 800 is D1, and the size of the maximum diameter of the constriction 800 is one of the critical parameters for the impact of the comminution effect. For example, when D1 is large, the ineffective grinding area in the soymilk maker 1000 is large, resulting in poor grinding effect of the soymilk maker 1000. When D1 is very small, it is not only inconvenient to assemble the heating structure on the cup 600, but also bottom-sticking is easily caused due to the high heat load on the bottom of the cup 600. The maximum diameter of the constriction 800 is further selectable as: d1 is not more than 130mm, so that the structure of the soymilk machine 1000 is optimized to a certain extent to form small-space shearing in the soymilk machine 1000 and improve the crushing effect.
