Wide juice extractor of adaptability

Technical Field

The utility model belongs to the technical field of food preparation machine, especially, relate to a juice extractor that adaptability is wide.

Background

Along with the improvement of living standard, various juicers continuously emerge, become the new pet of health preserving personage. The existing horizontal juicer generally comprises a base, a juice collecting cavity and a screw, wherein the motor is arranged inside the base, the juice collecting cavity is arranged on the base, and the screw is transversely arranged in the juice collecting cavity and comprises a screw body and a screw shaft. One end of the screw rod is a crushing section with a higher spiral height, and the other end of the screw rod is a grinding section with a lower spiral height. The juice collecting cavity is clamped with the base at one end corresponding to the grinding section, an end cover is arranged at the opening of the other end corresponding to the crushing section, a juice outlet for discharging juice with water and a slag outlet for discharging fruit residues with water are arranged at the lower part of the juice collecting cavity, and a feeding barrel for feeding materials is arranged at the upper part of the juice collecting cavity corresponding to the crushing section.

When needing to press juice, cut into cubic with materials such as the fruit that need press juice, vegetables earlier, then throw into the juice collecting cavity with cubic material through a feed cylinder, the starter motor to drive the screw rod and rotate, the spiral on the broken section screw rod is sheared blocky fruit vegetables material into less fragment gradually and gets into and hold in the space. Under the axial propelling action of the screw, the materials gradually move to the axial grinding section and are extruded, so that the fruit and vegetable materials are squeezed out of juice, and the residual materials are changed into fruit residues. The squeezed juice flows out through a juice outlet at the lower part of the juice collecting cavity, and the residue is discharged out through a residue outlet at the lower part of the juice collecting cavity. Of course, the disposal opening is provided with corresponding filtering holes so as to filter the juice mixed in the juice.

The basic principle of the screw driving the material to move axially is known as follows: the inclined acting force generated by the inclined spiral surface on the screw rod to the material when rotating can be decomposed into a circumferential component force and an axial component force, the circumferential component force drives the material to rotate, and the axial component force enables the material to move axially. When the material moves axially, the material generates sliding friction relative to the spiral surface of the screw.

However, the existing juice extractor has the following defects that firstly, because a certain friction force exists between the spiral surface of the screw and the materials, when soft materials such as ripe tomatoes are encountered, a larger friction force is formed due to the viscous action between the spiral surfaces of the material screws, and therefore, when the screw rotates, if the friction force between the materials and the spiral surface is larger than that between the materials and the juice collecting cavity, the phenomenon that the materials rotate synchronously along with the screw is easy to occur. That is, the material cannot move relative to the helicoid, thereby affecting the conveyance of the material. Secondly, for softer materials, the fibers of the pomace are shorter, and the juice and the pomace are easily and highly mixed together to be sticky after the materials are extruded, so that the juice and the pomace are not easy to separate, and the juice yield is influenced.

Meanwhile, if the extrusion gap between the screw and the juice collecting cavity is too small, the juice yield of hard fruits and vegetables can be improved, but thick juice can block the filter screen and cannot normally produce juice; if the extrusion gap between the screw and the juice collecting cavity is too large, poor crushing and reduced juice yield can be caused no matter the sensitive or soft fruits and vegetables are crushed.

Detailed Description

The present invention will be further described with reference to the accompanying drawings and the detailed description.

As shown in fig. 1 and 2, the juice extractor in this embodiment is a horizontal juice extractor, and specifically includes a base 1 having a motor inside, a working chamber 2 disposed on the base, and a screw 3 disposed in the working chamber, the screw includes a screw body 31 having a spiral on the surface, and a screw shaft 32 disposed in the screw body, one end of the screw is a crushing section 33, the other end of the screw is a grinding section 34, the radial height of the spiral of the crushing section is greater than the radial height of the spiral of the grinding section, and the screw shaft at one end of the crushing section is in transmission connection with a motor shaft. In addition, be equipped with the outlet 21 that is used for exporting the juice and the slag notch 41 that is used for discharging the pomace on the working chamber, and the working chamber includes horizontal arrangement's collection juice chamber 23, and the screw rod transversely sets up in the collection juice intracavity, and the collection juice chamber corresponds one end with the crushing section and is connected with the frame, and the other end opening part that collection juice chamber and grinding section correspond sets up end cover 24, is equipped with feed cylinder 25 at the collection juice chamber upside that corresponds crushing section one side. Generally, one end of the screw rod connected with the motor is positioned as a front end, and the end far away from the motor is positioned as a tail end; furthermore, because the material flows from the front end to the tail end of the screw, the upstream side and the downstream side can be defined according to the flowing direction of the material in the working cavity, namely, the material is thrown into the feeding cylinder and is firstly contacted with the screw and the working cavity to be the upstream, and the material is pushed to flow to be the downstream in sequence.

When the material cut into blocks is fed into the working cavity on one side of the corresponding screw rod crushing section through the feeding cylinder, the motor drives the screw rod to rotate, the screw rod crushing section with higher radial height cuts and crushes the material into small blocks when rotating, and a small amount of fruit juice is produced. When the screw rod drive material removed to grinding the section, because the radial height of grinding the section spiral is less than the spiral radial height of broken section, the space that is used for holding the material in the working chamber is littleer and littleer to make the material receive the extrusion and squeeze out fruit juice, fruit juice is through the outside outflow of juice outlet, and the pomace of squeezing out fruit juice is then outwards discharged from the slag notch.

Of course, grinding ribs may be provided on the inner side walls of the working chamber to allow the material to be ground sufficiently to extract the juice as it moves.

In order to be beneficial to driving materials to move forwards axially, a reciprocating driving structure capable of enabling the screw to move axially can be arranged between one end of a screw body of the screw and the corresponding working cavity.

Like this, when motor drive screw rotated and began to squeeze juice, the screw rod can produce axial reciprocating motion under the effect of reciprocal drive structure, when the screw rod was towards grinding section one side antedisplacement, both can promote the material and move forward, the phenomenon of avoiding appearing the material and following the screw rod and spin in situ appears, make the juice extractor adapt to the juice of soft or hard different nature fruit vegetables material, can form supplementary extrusion to the material again to the material that makes the grinding section forms the secondary and squeezes, promotes juice sediment separation degree and juice yield effectively.

When the screw rod was rolled back towards crushing section one side, the clearance grow between the screw rod of grinding section and the working chamber and form transient negative pressure to make the material produce an instant effect of relaxing, avoid the material effectively to remove along the helicoid because of the compaction, ensure that the pomace can outwards be discharged through the slag notch fast, meanwhile, the thick material of crushing section then can be under the effect of negative pressure to grinding section axial displacement. Along with the continuous rotation of the screw, the reciprocating motion formed by the screw drives the materials to spirally move and grind towards the grinding section, and the axial backward movement is generated to form negative pressure, so that the viscous materials can be normally pushed axially, and the squeezing effect of the fruit residues and the separation degree of the juice residues are obviously improved.

In the present embodiment, the crushing section in which the screw is connected to the motor is the rear side and the rear end, and the grinding section of the screw is the front side and the front end. And thus define the front-to-back direction of other components or actions.

And in order to meet the requirements of different types of fruits and vegetables, a squeezing cavity is further arranged between the tail end of the screw rod and the slag outlet. The squeezing cavity contains the marc formed by the extrusion of the screw rod, and further squeezes and separates juice in the squeezing cavity, especially when the screw rod moves back and forth, the marc in the squeezing cavity bears the squeezing driving force of the screw rod in the axial direction, and the separation of the marc and the juice is accelerated.

The ratio of the sectional areas of the extrusion cavity and the slag outlet in the axial direction is not less than 4, so that a large area difference exists between the extrusion cavity and the slag outlet, fruit residues cannot be immediately discharged from the slag outlet after entering the extrusion cavity and can be further extruded in the extrusion cavity, for soft food materials, the extrusion cavity can contain a part of residue-juice mixture which is not fully separated, viscous juice cannot be accumulated at the juice outlet, and on one hand, the normal filtration of the juice outlet, particularly a filtering hole, is ensured; on the other hand, the residue and juice mixture is further extruded in the extrusion cavity, and particularly is pressed by the extrusion back and forth movement, so that the residue and juice can be quickly separated, and the high-efficiency work of the juice extractor is ensured.

As a preferable scheme, as shown in fig. 2 and fig. 3, the reciprocating driving structure includes a spiral driving inclined surface 311 disposed on the end surface of the screw body of the crushing section, and a pushing protrusion 231 disposed in the juice collecting cavity and abutting against the driving inclined surface.

It should be noted that the spiral driving inclined surface is a continuous curved surface from low to high to low in the axial direction. The screw is subject to the reverse extrusion force of the material during extrusion and has the tendency of moving towards the front end, so that the spiral driving inclined plane is pushed to be always in contact with the pushing protrusion, when the pushing protrusion is in contact with the lower end of the inclined plane, the screw is close to the motor, the extrusion gap between the screw and the extrusion container is the largest, the volume of the extrusion cavity is the largest, when the pushing protrusion is in contact with the top end of the inclined plane, the pushing protrusion pushes the screw to move towards the tail end, the extrusion gap between the screw and the extrusion container is the smallest, and the volume of the. When the motor drives the screw rod to rotate and begin to squeeze juice, the screw rod drives the material to move forwards, correspondingly, the material forms a backward reaction force to the screw rod, and the contact position of the pushing bulge and the driving inclined plane is continuously changed. When the contact point of the pushing bulge and the driving inclined plane gradually moves from the starting end to the ending end of the driving inclined plane, the screw rod axially moves a distance towards one side of the grinding section under the action of the axial thrust of the pushing bulge, so that the material is pushed to axially move, and the material is compressed for the second time; when the contact point of the pushing protrusion and the driving inclined plane is moved to the starting end again by the stopping end of the driving inclined plane, the screw rod can be quickly and axially retreated under the reaction force of the material, so that the materials are loosened and adsorbed by negative pressure to push. The utility model discloses a top pushes away protruding promotion screw rod axial antedisplacement to utilize the reaction force of material to make the screw rod retreat naturally ingeniously, thereby can greatly simplify the reciprocating drive structure, be favorable to reduce cost, improve the reliability of juice extractor work.

In addition, the screw shaft and the motor shaft can be connected through splines, so that on one hand, the motor shaft is favorable for outputting enough torque to drive the screw to rotate, and on the other hand, the screw can generate axial reciprocating movement relative to the motor shaft while rotating.

As another preferred solution, we can provide a circular elastic positioning diaphragm 4 in the end cover, a supporting ring 5 on the downstream side of the positioning diaphragm, which abuts the positioning diaphragm, and a through hole in the middle of the positioning diaphragm to form the slag outlet 41. The screw body 31 comprises a screw body 310 and a positioning plug 35, the screw body 310 is hollow and arranged at the tail end, so that the weight of the screw can be reduced, the cost of the screw is reduced, the screw is convenient to take, the positioning plug 35 is arranged at the opening of the screw body to seal the opening of the screw body, and the positioning plug is fixedly connected with the screw body. The outside of location stopper sets up the head and is conical reference column 350, and the reference column passes in the slag notch gets into the end cover to make the grinding section of screw rod obtain effectual support, can reduce rocking and the noise at work of screw rod, and the location diaphragm still can prevent effectively that the fruit juice of squeezing out from getting into in the end cover. In addition, the slag outlet is arranged at the front end of the end cover far away from the juice collecting cavity.

When juice is squeezed, the fruit residues with pressure in the grinding section can extrude the positioning diaphragm, on one hand, the supporting ring piece can effectively support the positioning diaphragm in the axial direction of the working cavity, and the positioning diaphragm can be prevented from seriously bulging or even cracking towards one side of the end cover under the extrusion of the fruit residues; on the other hand, the fruit residues with pressure can stretch the residue outlet on the positioning membrane to enter the end cover and are discharged outwards through the residue outlet on the end cover.

It should be noted that the slag hole of the positioning membrane should be smaller than the inner hole of the supporting ring sheet, so that the slag hole can be expanded and the fruit residues can be extruded. Of course, the maximum juice outlet gap between the positioning membrane and the positioning column can be conveniently controlled by controlling the aperture controlled in the supporting ring sheet.

Preferably, the end cover comprises a cylindrical main cylinder 241 with one end clamped on the juice collecting cavity and a steering pipe 242 connected to the other end of the main cylinder, the steering pipe is bent downwards in an arc shape and forms the residue discharge port, that is, the steering pipe is a 90-degree bent pipe, and the positioning membrane and the supporting ring are arranged at the joint of the steering pipe and the main cylinder. When the steering tube is clamped on the main cylinder body, the membrane and the supporting ring piece can be clamped and fixed, so that the assembly, the disassembly and the assembly after use are convenient, and the cleaning is convenient.

The main cylinder 241 and the steering tube 242 are provided as two fittings and are fixedly connected to form an end cover, for example, the main cylinder and the steering tube may be fixedly connected by screws, and the positioning membrane is clamped at the connection position of the main cylinder and the steering tube.

Because the slag discharging port is formed by bending the steering pipe downwards in an arc shape, the fruit slag extruded from the slag discharging port is loosened in the end cover and can be discharged outwards from the downward slag discharging port along the arc steering pipe under the action of self gravity, so that the moving resistance of the fruit slag before being discharged is favorably reduced, and the fruit slag is prevented from being detained at the slag discharging port. It can be understood that the pipe diameter of the steering pipe can be properly increased, so that the caliber of the slag discharge port is correspondingly increased, and the rapid discharge of the fruit residues is facilitated. The positioning film can make the material form a 'gate' to prevent the mixture of fruit residue and fruit juice from discharging from the residue outlet.

In order to facilitate the filtration of the juice, a squeezing barrel 6 can be arranged between the screw and the juice collecting cavity, a filtering hole 61 is arranged on the lower side of the squeezing barrel, a tapered necking 62 which gradually shrinks is arranged at the front end of the squeezing barrel, and the tapered necking is positioned in the end cover, so that the squeezing cavity 26 can be defined by the tapered necking, the end face of the grinding section of the screw and the positioning column.

When the material moved forward under the drive of screw rod, the material got into in the recipient, and the juice of squeezing out can outwards flow from the juice outlet after the filtration of downside filtration pore, is favorable to promoting the purity of juice. The pomace formed by grinding and extrusion in the grinding section enters the extrusion cavity.

When the screw rod moved forward under the effect of reciprocal drive structure, the screw rod ground section terminal surface can carry out the propelling movement of circumference to the pomace of extrusion intracavity for the pomace can form extrusion once more in the annular extrusion intracavity of awl, thereby further improves the juice sediment resolution, and the fruit juice of extruding then can flow back along the inside wall of toper throat, finally outwards flows through going out the juice mouth.

Preferably, the circumferential surface of the screw body of the grinding section is clamped with a retaining ring 341, when the reciprocating driving structure makes the screw move to one end of the slag outlet, the extrusion cavity is reduced, and the retaining ring is pressed against the material in the extrusion cavity, thereby effectively avoiding the backflow phenomenon of the pressurized fruit residues.

The stopping check ring is arranged between the screw rod body and the positioning plug and is clamped by the positioning plug and the screw rod body, when the positioning plug and the screw rod body are installed in place, an annular groove is formed between the positioning plug and the screw rod body, and the stopping check ring is positioned in the annular groove. Preferably, the stopping retaining ring is elastic material, on the one hand, can play the function that blocks and promote the pomace, and on the other hand, the stopping retaining ring still can play sealed effect to between location stopper and the screw rod body, prevents inside the fruit juice infiltration advances the screw rod.

Furthermore, a plurality of juice outlet gaps 621 which extend along the axial direction and penetrate through the edge of the tapered necking are formed in the tapered necking, and the juice outlet gaps are uniformly arranged in the circumferential direction, so that the tapered necking forms a plurality of sheet claws with separated front ends. When the material in the toper throat received the extrusion and pressure rises, the piece claw that is separated by a juice gap outwards expands and opens, makes the opening grow of toper throat on the one hand, and on the other hand makes a juice gap grow, has guaranteed that fruit juice can be quick by a juice gap discharge, and simultaneously, the pomace also can be discharged by the opening part is quick. When the material pressure in the conical necking is reduced, the sheet claw is restored, the opening of the conical necking and the juice outlet gap are restored to the original shape, and therefore the material of mixed oil and juice can be prevented from being sent out forwards.

In order to further enhance the squeezing action on the marc, as shown in fig. 4, the screw grinding section further includes a re-squeezing section 36 with a reduced diameter at the end, and the end face of the re-squeezing section is a spiral surface. When the screw rotates, the re-squeezing section can continuously push and squeeze the mixture in the squeezing cavity so as to improve the separation degree of the residue and the juice. Particularly, the screw rod moves axially in cooperation with the reciprocating driving structure, so that the materials are extruded for the second time, and the end face of the screw rod body extrudes the fruit juice in the extrusion cavity again. Meanwhile, the spiral end surface of the secondary squeezing section can perform circular compaction and relaxation effects on the fruit residues in the squeezing cavity, so that the fruit residues are further squeezed, and the juice residue separation degree and the juice yield are further improved.

Furthermore, the circumferential surface of the re-squeezing section can be provided with re-squeezing teeth 37, and the material facing surface of the re-squeezing teeth close to the conical necking is a spiral surface. When the screw rod rotates, the double-squeezing teeth can perform axial pushing and squeezing effects on the fruit residues entering the squeezing cavity, and can stir up and loosen the fruit residues so as to improve the juice yield and the separation degree of the juice residues and ensure that the fruit residues move forwards and are discharged outwards through the residue outlet.

In order to enhance the extrusion of the material, the grinding section of the screw comprises a conical extrusion section 38 with a small front end and a large rear end, the large end of the extrusion section is close to the crushing section, and the extrusion container comprises a conical extrusion inner wall 63 corresponding to the extrusion section, so that a radial extrusion gap is formed between the extrusion section and the extrusion cavity, and the extrusion gap is uniformly arranged in the axial direction.

For better pushing of the material and for preventing the swinging of the front end of the screw, the grinding section of the screw further comprises a cylindrical conveying section 39 located downstream of the extrusion section, the extrusion container comprising a cylindrical conveying container 64 corresponding to the conveying section 39. The material is accomplished the extrusion back by the extrusion section, transmits to the transport section, carries section and transport cylinder cylindricality setting, and the extrusion clearance between the two can not change along with the screw rod back-and-forth movement, and the material is sustainable to be carried to the extrusion intracavity, and because the clearance can not change, the material receives the extrusion in the extrusion section. If the conveying section gap changes along with the extrusion section, the materials can be quickly discharged from the conveying section when being extruded, and the function of extruding the juice can not be realized. Simultaneously, because the clearance can not change, the transport section still can carry on spacingly to the screw rod end, prevents that the screw rod from terminal the swing in the course of the work. The conveying cylinder is further internally provided with ribs along the axial direction, so that the conveying cylinder can recall and push materials to be discharged forwards along the direction of the ribs.

When the reciprocating driving structure makes the screw rod move forward axially, the extrusion gap formed by the conical extrusion section and the conical extrusion cavity is correspondingly reduced, so that the material in the extrusion gap is extruded. That is to say, reciprocal drive structure can make the material obtain a lot of extrusion, promotes juice yield and juice sediment separation degree remarkably.

In addition to the preferred embodiments described above, other embodiments of the present invention are also possible, and those skilled in the art can make various changes and modifications according to the present invention without departing from the spirit of the present invention, which should fall within the scope of the present invention defined by the appended claims.
