Description

Simple structure's juice extractor

Technical Field

The invention belongs to the technical field of food processing machines, and particularly relates to a juicer with a simple structure.

Background

Along with the improvement of living standard, various juicers continuously emerge, become the new pet of health preserving personage. The existing vertical juicer generally comprises a base, a juice collecting cavity, a screw rod, an extruding cylinder and an upper cover, wherein the base is internally provided with a motor, the juice collecting cavity is connected with the base, the screw rod is longitudinally arranged in the juice collecting cavity, the extruding cylinder is arranged between the screw rod and the juice collecting cavity, the upper cover is arranged at an opening at the upper part of the juice collecting cavity, a juice outlet gap is arranged on the extruding cylinder, the screw rod comprises a screw rod body and a screw rod shaft, a spiral is arranged on the surface of the screw rod body, the upper part of the screw rod is a crushing section with a higher spiral height, and therefore a larger accommodating gap; the lower part of the screw is a grinding section with a lower spiral height, so that a smaller accommodating gap is formed between the screw and the juice collecting cavity. The lower part of the juice collecting cavity is provided with a juice outlet and a residue outlet. In order to avoid the rotation of the extruding cylinder during the juice extraction, a corresponding positioning structure is arranged between the lower part of the extruding cylinder and the bottom of the juice collecting cavity.

When needing to press juice, cut into the cubic with the fruit, the vegetables of needs pressing juice earlier, then put into the recipient with cubic material in, the starter motor to drive the screw rod and rotate, the higher spiral of broken section can be sheared cubic fruit vegetables material into less fragment gradually and get into in the great clearance that holds in upper portion. Under the axial propelling movement effect of the material pushing surface on the lower side of the spiral, the material gradually moves downwards to the grinding section with a smaller accommodating gap, the fruit and vegetable materials at the moment are extruded to form fruit and vegetable juice and corresponding residues, the fruit and vegetable juice flows outwards from a juice outlet at the lower part of the juice collecting cavity after being filtered by a juice outlet gap of the extruding cylinder, and the residues are discharged outwards from a residue outlet at the lower part of the juice collecting cavity.

The installation procedure of the existing juice extractor before use is as follows: firstly, the juice collecting cavity is arranged and positioned on the machine base, then the extruding barrel is arranged and positioned in the juice collecting cavity, then the screw rod is arranged in the extruding barrel, the lower end of the screw rod shaft is in spline connection with a motor shaft in the machine base, and finally the upper cover is screwed and covered at the opening at the upper part of the juice collecting cavity. This structure and the corresponding mounting have the following drawbacks: the extruding cylinder and the upper cover need to be respectively positioned and installed, thereby increasing the inconvenience when a user uses the extruding cylinder and the upper cover. In particular, when the container is mounted in the juice collecting chamber, the lower end of the container is positioned in the juice collecting chamber, and when the upper cover is closed, the upper cover still needs to be matched with the upper end of the container, and the upper end of the container is positioned. Because the recipient upper end is in unstable state this moment, consequently, the user hardly makes upper cover lower extreme and recipient upper end form the cooperation rapidly and fix a position to be unfavorable for promoting the user experience of juice extractor.

Disclosure of Invention

The invention aims to provide a juicer with a simple structure, which can reduce the steps of dismounting and mounting the juicer when in use, and can completely eliminate the problem of difficult positioning between the upper end of a squeezing barrel and an upper cover, thereby greatly improving the user experience of the juicer when in use.

In order to achieve the purpose, the invention adopts the following technical scheme:

the utility model provides a simple structure's juice extractor, including the frame that has the motor, locate the juice collecting cavity on the frame, vertically locate the screw rod of juice collecting cavity, be located the screw rod and collect between the juice chamber and upper and lower open-ended recipient, the juice collecting cavity is equipped with juice outlet and slag notch, and collection juice chamber upper portion opening part is equipped with the upper cover, the upper end and the upper cover of recipient are connected as an organic whole component, collection juice chamber bottom is equipped with the cooperation bulge loop, and the cooperation is pegged graft to the lower extreme of recipient in the cooperation bulge loop to form out the juice gap between recipient lower extreme and cooperation bulge loop.

The upper end of the extruding cylinder and the upper cover are connected into an integral component, so that a user does not need to install and position the extruding cylinder and the upper cover respectively when using the juice collecting cavity, only a screw rod is installed in the juice collecting cavity firstly, then the extruding cylinder and the upper cover are installed on the juice collecting cavity together, the extruding cylinder is sleeved outside the screw rod, the lower end of the extruding cylinder and a matching convex ring at the bottom of the juice collecting cavity form inserting matching, and therefore the lower end of the extruding cylinder is reliably positioned, and when the upper cover is screwed and covered on an opening at the upper end of the juice collecting cavity, the upper end of the extruding cylinder can be reliably positioned together. That is, the present invention simplifies two installation steps of the container and the upper cover into one installation step. Particularly, the matching convex ring at the bottom of the juice collecting cavity is of a fixed structure, so that the lower end of the extruding container can be conveniently in insertion fit with the matching convex ring for positioning, and a juice outlet gap is formed between the lower end of the extruding container and the matching convex ring, so that the juice in the extruding container can flow out through the juice outlet gap.

It can be understood that, compare with the filtration pore that directly forms on the recipient, the play juice gap that cooperation formed through the grafting between recipient lower extreme and the cooperation bulge loop has longer length on the one hand to be favorable to improving juice speed and play juice efficiency, on the other hand, conveniently controls the width in juice gap, thereby be convenient for manufacturing. Particularly, after the juice extraction is finished, the user can disassemble the upper cover and the extruding cylinder, the extruding cylinder and the juice collecting cavity are separated from each other, namely, the juice outlet gap is of an open separation structure, the user can clean the extruding cylinder and the juice collecting cavity respectively, and the cleaning is particularly convenient when partial fruit residues are left in the juice outlet gap.

It will be appreciated that, because the container and the lid are relatively fixed, the upper end of the container is reliably positioned after the lid is closed. Therefore, the juice outlet gap is arranged between the lower end of the extruding cylinder and the matched convex ring. That is, the lower end of the extruding container can be provided with no corresponding positioning structure, thereby greatly simplifying the structures of the extruding container and the juice collecting cavity and facilitating the installation and connection.

Preferably, the extrusion container is a straight cylinder shape with the upper part and the lower part consistent with each other or an inverted cone cylinder shape with the upper part small and the lower part large.

The extrusion container is set to be in a straight barrel shape with the same height or in an inverted cone barrel shape with a small upper part and a large lower part, so that the extrusion container is greatly sleeved on the outer side of the screw rod from top to bottom, and the screw rod and the extrusion container are convenient to mount and dismount. When the extrusion container is set to be in a vertical consistent straight barrel shape, the extrusion container can be conveniently molded, meanwhile, the gap between the extrusion container and the screw rod is conveniently controlled, when the upper end of the extrusion container is ensured to have a sufficient opening, the oversize of the lower end of the extrusion container is avoided, and the reduction of the overall dimension of the juicer is facilitated. When the extrusion cylinder is in a shape of an inverted cone with a small upper part and a big lower part, the extrusion cylinder can be sleeved on the outer side of the screw rod from top to bottom greatly, so that the juice extractor is convenient to install and use.

Preferably, a plurality of axial positioning convex ribs are arranged on the inner side wall of the matching convex ring at intervals, and the outer side wall of the lower end of the extrusion container is attached to the positioning convex ribs.

When the extrusion container is in inserted connection and matched with the matching convex ring, the outer side wall of the lower end of the extrusion container is attached to the positioning convex rib, so that the lower end of the extrusion container is positioned by a reliable center, the extrusion container is prevented from shaking during juicing, and the vibration and the noise during juicing are favorably reduced. In particular, the positioning ribs separate the outer sidewall of the lower end of the container from the inner sidewall of the mating collar to form a radial juice outlet gap. Therefore, a juice outlet gap of the end surface is formed between the lower end surface of the extruding cylinder and the bottom wall of the juice collecting cavity. When the juice is squeezed, the juice can flow outwards through the juice outlet gap on the end face, then flow upwards through the radial juice outlet gap, cross the upper edge of the matched convex ring and flow outwards, and finally are output outwards through the juice outlet.

It can be understood that adjacent two positioning convex ribs can limit the width and the flow path of the radial juice outlet gap, and the juice can flow outwards through the radial juice outlet gap quickly by reasonably setting the distance and other parameters between the positioning convex ribs, so that the flow speed of the juice is increased. In addition, when the fruit juice flows upwards in the radial juice outlet gap, the small pulp and the pomace which are mixed in the fruit juice in a trace amount can be further precipitated and filtered, and the purity and the taste of the fruit juice can be further improved.

It should be noted that, when we install the container and the upper cover, the lower end of the container can be inserted and matched in the matching convex ring at any angle and attached to the positioning convex rib, so that the container and the upper cover can be installed conveniently.

Preferably, the juice outlet gap comprises a plurality of juice outlet grid holes arranged at the lower part of the extruding cylinder, and the juice outlet grid holes are arranged at intervals in the circumferential direction of the extruding cylinder.

The juice at the lower part of the extruding cylinder can flow out through the juice outlet grid holes and then flow out through the juice outlet gap between the extruding cylinder and the matching convex ring. It can be understood that we can rationally set up the width in the play juice gap that is formed by the cooperation of grafting of recipient and cooperation bulge loop to ensure the filter effect to fruit juice, and go out the juice bars hole and then can suitably increase the width, make things convenient for processing manufacturing on the one hand, the jam of reducible pomace simultaneously is favorable to promoting out the juice speed, and the washing after facilitating the use, and mix trace pulp and pomace in the fruit juice that flows through a juice bars hole, can be blockked effectively and filter by a juice gap. That is, the juice outlet grid hole can perform coarse filtration on the juice, and the juice outlet gap can perform fine filtration.

Preferably, the height of the juice outlet grid hole is not lower than that of the matching convex ring.

Because the height of the juice outlet grid hole is not lower than that of the matching convex ring, part of the juice which flows out from the upper part of the juice outlet grid hole can directly flow out into the juice outlet without being blocked and limited by the matching convex ring, and the juice outlet speed and the juice outlet efficiency are improved. It will be appreciated that the juice in the container will flow downwardly and collect at the bottom of the container under its own weight, with the material, marc, of the container being at a higher pressure closer to the bottom wall of the juice collection chamber. Therefore, the juice mainly flows out of the upper juice outlet grid hole, the pomace mixed in the juice in the part is not easily extruded outwards through the upper part of the juice outlet grid hole due to low pressure, and the juice at the bottom of the extruding cylinder is blocked and limited by the matching convex ring and the juice outlet gap after being extruded out of the lower juice outlet grid hole, so that the purity of the juice can be ensured.

Preferably, the outer side wall of the lower part of the extrusion container is provided with a positioning ring rib positioned between adjacent juice outlet grid holes, and the positioning ring rib is attached to the inner side wall of the matched convex ring.

When the extrusion container is inserted and matched into the matching convex ring, the positioning ring rib is attached to the inner side wall of the matching convex ring, so that the lower part of the extrusion container is reliably positioned in the center. Meanwhile, the positioning ring rib enables a radial juice outlet gap to be formed between the outer side wall of the extruding cylinder and the inner side wall of the matched convex ring, and juice which flows outwards through the juice outlet grid hole can flow upwards through the radial juice outlet gap and is output outwards through the juice outlet after passing over the upper edge of the matched convex ring. The radial juice outlet gap is beneficial to the precipitation and filtration of trace fruit residues mixed in the upward flowing fruit juice.

It can be understood that the inside wall of cooperation bulge loop can set up a reasonable drawing of patterns inclination usually, and the drawing of patterns when conveniently gathering juice chamber injection moulding on the one hand, on the other hand, the lower extreme of the recipient cooperation of pegging graft of being convenient for is in the cooperation bulge loop, avoids producing the collision between the two and interferes. Therefore, the positioning ring rib can be arranged at the position, close to the lower end face, of the extrusion container as much as possible, so that an enough gap is formed between the outer diameter of the positioning ring rib and the inner diameter of the opening of the matched convex ring. When the extrusion cylinder is inserted and matched into the matching convex ring from top to bottom, collision interference between the positioning ring rib and the matching convex ring can be avoided, and the juice extractor is convenient to install and use.

Preferably, a plurality of juice outlets which are uniformly distributed in the circumferential direction and extend to the upper end face are formed in the inner side wall of the matching convex ring, matching convex blocks are formed between every two adjacent juice outlets, matching notches are formed in the positions, corresponding to the matching convex blocks, of the lower end of the extruding container, and juice outlet gaps are formed between two side edges, close to the extruding container, of the matching convex blocks and two side edges, close to the matching convex ring, of the matching notches.

It will be appreciated that the upper cover is typically attached to the upper opening of the juice collecting chamber by a screw-on connection, i.e. the upper cover and the container are rotated through a snap-on angle when they are mounted. The inner side wall of the matching convex ring is provided with a recess, the lower end of the extruding cylinder is provided with a matching notch, when an upper cover and the extruding cylinder are positioned and installed at an opening at the upper part of the juice collecting cavity, the lower end of the extruding cylinder is supported by the inner side wall of the matching convex ring, so that the lower end of the extruding cylinder is reliably positioned at the center, the matching notch is just corresponding to a matching convex block formed between adjacent juice outlet recesses, at the moment, an axial juice outlet gap can be formed between the edges of two sides, close to the extruding cylinder, of the matching convex ring and the edges of two sides, close to the matching convex ring, of the matching notch, and the juice outlet recesses form a radial juice outlet gap between the extruding cylinder and the. The juice in the recipient flows outward through axial juice gap earlier, then upwards flows in radial juice gap to cross the upper edge of cooperation bulge loop and outwards flow, finally outwards export through the juice mouth.

It can be understood that, because the axial juice outlet gap is formed by the matching gap of the extruding cylinder and the matching convex block of the matching convex ring, the width size of the axial juice outlet gap can be accurately controlled, the filtering effect of the juice is ensured, and the matching gap has larger width, thereby being convenient for molding and cleaning after use.

Preferably, the juice outlet gap comprises a bottom gap and a side gap, the bottom gap is formed between the lower end face of the extruding container and the bottom wall of the juice collecting cavity, the side gap is formed between the outer side wall of the lower portion of the extruding container and the inner side wall of the matched convex ring, and the bottom gap is communicated with the side gap.

When the juice enters the side gap after being filtered through the bottom gap, the juice can flow upwards in the side gap, flows outwards beyond the upper edge of the matching convex ring and is finally output outwards through the juice outlet. When fruit juice flows upwards in the side gap, a small amount of tiny pomace mixed in the fruit juice can be automatically deposited at the bottom of the side gap under the action of gravity, so that the purity and the taste of the fruit juice are favorably improved.

Preferably, the matching convex ring is provided with a matching convex tooth, the lower end of the extruding cylinder is provided with an opening corresponding to the matching convex tooth, and the juice outlet gap is formed between the edges of the two sides of the matching convex tooth close to the opening.

It can be understood that the height of the matching convex ring is inversely proportional to the strength and rigidity of the matching convex ring, so that the height of the matching convex ring can be properly reduced, the matching convex teeth with lower height are arranged on the matching convex ring, and correspondingly, the lower end of the extrusion container is provided with an opening corresponding to the matching convex teeth. When the upper cover and the extruding cylinder are positioned and installed at the opening at the upper part of the juice collecting cavity, the lower end of the extruding cylinder is supported by the inner side wall of the matching convex ring, so that the lower end of the extruding cylinder is reliably positioned at the center, the opening at the moment just corresponds to the matching convex tooth, and an axial juice outlet gap is formed between the edges of the two sides of the matching convex tooth, which are close to the opening. That is, in this scheme, we can both ensure the strength of the mating bulge loop and the mating bulge tooth and conveniently form the juice gap. Particularly, the inner side wall of the matching convex ring is a flat and smooth cylindrical surface, so that the lower end of the extrusion container is greatly convenient to be in plug-in fit with the matching convex ring, and the lower end of the extrusion container is reliably supported by the matching convex ring.

Preferably, the depth of the juice outlet concave is a, and a is more than or equal to 0.1mm and less than or equal to 0.5 mm.

Through the sunken degree of depth a of reasonable control play juice, can form suitable radial play juice gap, both had been favorable to promoting out juice speed and play juice efficiency, can make fruit juice again can effectual secondary precipitate filter, be favorable to promoting the purity and the taste of fruit juice. When a is less than 0.1mm, the juice can be obstructed from flowing out, and the juice outlet speed and the juice outlet efficiency are influenced. When a is more than 0.5mm, the radial juice outlet gap formed by the juice outlet depression weakens the blocking effect on fruit residues, and juice mixed in the juice flowing out through the axial juice outlet gap can easily flow out through the radial juice outlet gap, so that the purity and the taste of the juice are influenced.

Therefore, the invention has the following beneficial effects: the step of dismouting when both reducible juice extractor uses can be eliminated again completely and the difficult problem of location between recipient upper end and the upper cover to user experience when greatly promoting the juice extractor and using.

Detailed Description

The invention is further described with reference to the following detailed description and accompanying drawings.

The first embodiment is as follows:

as shown in figure 1, the juicer with the simple structure comprises a base 1, a juice collecting cavity 2, a screw rod 3 and an extruding cylinder 4, wherein the motor 11 is arranged inside the base, the juice collecting cavity 2 is connected onto the base, the screw rod 3 is longitudinally arranged in the juice collecting cavity, the extruding cylinder 4 is positioned between the screw rod and the juice collecting cavity and is provided with an upper opening and a lower opening, an upper cover 12 with a feeding hole is arranged at the upper opening of the juice collecting cavity, the screw rod comprises a screw rod body 31 with a spiral surface and a screw rod shaft 32 in the screw rod body, and the motor is connected with the screw rod shaft through a transmission.

For convenient installation and use, the upper end of the extrusion container is connected with the inner side of the upper cover to form an integral component, and the bottom of the juice collecting cavity is provided with a circular matching convex ring 23 which is integrally formed in a protruding mode. When the upper cover is installed and positioned at the opening at the upper end of the juice collecting cavity through the turnbuckle structure, the lower end of the extruding cylinder is inserted and matched in the matching convex ring, so that a juice outlet gap for the juice to flow outwards is formed between the lower end of the extruding cylinder and the matching convex ring.

When juice is required to be squeezed, a user needs to install and position the juice collecting cavity on the base, then a screw rod is installed in the juice collecting cavity, the lower end of a screw rod shaft of the screw rod is in transmission connection with an output shaft of a transmission mechanism in the base, then the extruding cylinder and the upper cover are installed on the juice collecting cavity together, the extruding cylinder is sleeved outside the screw rod from top to bottom at the moment, and the lower end of the extruding cylinder and a matching convex ring at the bottom of the juice collecting cavity form splicing matching. When the upper cover is fastened at the opening at the upper end of the juice collecting cavity in a rotating mode, the lower end of the extruding cylinder can be reliably supported and centrally positioned in a matched mode through the convex ring, a corresponding juice outlet gap is formed, the upper end of the extruding cylinder connected with the upper cover into a whole is also reliably centrally positioned and circumferentially positioned, and therefore the extruding cylinder can be effectively prevented from rotating when juicing.

After the juicing is finished, the upper cover and the squeezing barrel can be detached by a user, the squeezing barrel and the juice collecting cavity are separated from each other, so that the juice outlet gap is of an open separation structure, and the squeezing barrel and the juice collecting cavity can be cleaned by the user respectively. Particularly, when part of the fruit residues are blocked and remained in the juice outlet gap, the juice outlet gap of the separation structure can be used for conveniently cleaning the remained fruit residues.

Preferably, the upper end opening of the extrusion container is integrally connected to the inner side wall of the upper cover, so that the upper cover and the extrusion container can be integrally formed through an injection molding process, and the manufacturing efficiency and the dimensional precision are improved. Alternatively, the plastic upper cover and the extrusion container can be welded together by an ultrasonic welding process, so that the injection molding die structure is simplified.

In order to facilitate the installation of the extruding container in the juice collecting cavity, the extruding container can be in a vertical consistent straight barrel shape, so that the molding forming of the extruding container is facilitated, meanwhile, the gap between the extruding container and the screw rod is conveniently and accurately controlled, and the juicing effect is further improved. It is known that when the opening at the upper end of the extrusion container is large, the block-shaped materials can be favorably fed into a gap between the opening at the upper end of the extrusion container and the screw. And the straight barrel-shaped extrusion container is beneficial to increasing the opening size of the upper end of the extrusion container as much as possible under the same size of the lower end of the extrusion container, so that the overlarge overall dimension of the juice collecting cavity can be avoided, the overall dimension of the juice extractor can be further reduced, and the materials can be conveniently fed into a gap between the extrusion container and the screw rod.

Alternatively, the container may be a tapered container having a small top and a large bottom. When the extrusion cylinder is sleeved on the screw rod from top to bottom, the larger opening at the lower end of the extrusion cylinder is opposite to the smaller upper end of the screw rod, so that the extrusion cylinder is sleeved on the outer side of the screw rod from top to bottom, and the assembly and disassembly of the extrusion cylinder and the installation and use of the juicer are facilitated.

As a preferable scheme, as shown in fig. 2 and 3, a plurality of axial positioning convex ribs 24 can be arranged on the inner side wall of the matching convex ring, the positioning convex ribs are uniformly distributed in the circumferential direction of the matching convex ring, when the extruding container is installed in the juice collecting cavity, the outer side wall of the lower end of the extruding container is attached to the positioning convex ribs, so that the lower end of the extruding container is reliably positioned by the center, the extruding container is prevented from shaking during juice extraction, and the vibration and noise during juice extraction can be reduced. At the same time, the positioning ribs separate the outer sidewall of the lower end of the container from the inner sidewall of the mating collar to form a radial juice outlet gap 231. Therefore, a juice outlet gap of the end surface is formed between the lower end surface of the extruding cylinder and the bottom wall of the juice collecting cavity. When juicing, the juice flows outwards through the juice outlet gap of the end face, then flows upwards through the radial juice outlet gap, flows outwards over the upper edge of the matched convex ring, and finally is output outwards through the juice outlet.

It should be noted that, in order to ensure the dimensional accuracy and the filtering effect of the radial juice outlet gap, a demoulding inclination of 3 to 5 degrees can be arranged on the inner side wall of the matching convex ring, so that the inner side wall of the matching convex ring forms a conical cylinder shape with a large upper part and a small lower part, correspondingly, the outer side wall of the lower end of the extrusion container is arranged into a conical cylinder shape with a large upper part and a small lower part, and the conical angle of the outer side wall of the matching convex ring is matched with the conical angle of the inner side wall of the matching convex ring, thereby being beneficial to the insertion and matching of the extrusion container into the matching convex ring at any angle, and.

Of course, it is necessary to provide a juice outlet 22 and a residue outlet 21 at the lower part of the juice collecting chamber to output juice outwards and discharge the residue.

As a second preferred option, as shown in FIG. 4, several holes 41 are provided in the lower part of the container, which holes form part of the juice outlet gap. The juice outlet grid hole is directly formed on the extruding cylinder, so that the juice outlet grid hole can be arranged at a higher position at the lower part of the extruding cylinder, and when materials are sheared by the crushing section at the upper part of the screw rod to form juice and flow downwards along the inner side wall of the extruding cylinder, the materials can directly flow outwards through the juice outlet grid hole. Because the fruit juice and the material at this moment do not receive the great pressure of screw rod yet, therefore, we can set up the juice bars hole of great width, are favorable to the quick outflow of fruit juice, can avoid material or pomace outwards to discharge simultaneously.

When a radial juice outlet gap is formed between the outer side wall of the extruding container and the inner side wall of the matched convex ring, the juice outlet grid hole can be axially arranged at the lower position of the lower part of the extruding container, and can extend to the lower end face of the extruding container, so that the injection molding of the juice outlet grid hole is facilitated, and a complex core pulling mechanism is avoided. At the moment, the juice flows outwards through the juice outlet grid holes and then flows outwards through the radial juice outlet gap between the extruding container and the matching convex ring.

It should be noted that we can reasonably set the width of the juice outlet gap formed by the insertion and matching of the extruding cylinder and the matching convex ring, thereby ensuring the filtering effect on the juice, and the width of the juice outlet grid hole can be properly increased, on one hand, the processing and the manufacturing are convenient, and simultaneously, the blockage of the fruit residues can be reduced, the juice outlet speed is favorably promoted, and the cleaning after the use is convenient. When a small amount of pulp and pomace are mixed in the fruit juice and flow out through the juice outlet grid holes, the pulp and the pomace can be effectively blocked and filtered by the juice outlet gaps. That is to say, the juice outlet grid hole can play a coarse filtering role for the juice, and the juice outlet gap can play a fine filtering role, so as to ensure that the juice has higher purity and good taste.

It will be appreciated that the juice in the container will flow downwardly and collect at the bottom of the container under its own weight, and the material, marc, in the container will be subject to a greater screw pressure closer to the bottom wall of the juice collection chamber. Preferably, the height of the juice outlet grid hole is not lower than that of the matching convex ring, so that part of the juice flowing out from the upper part of the juice outlet grid hole can directly flow out into the juice outlet without being blocked and limited by the matching convex ring, and the juice outlet speed and the juice outlet efficiency are improved. The squeezing force born by the fruit juice close to the upper part of the juice outlet grid hole is small, so that the part of fruit juice mainly flows out of the juice outlet grid hole at the upper part, the fruit residues mixed in the part of fruit juice cannot be squeezed out outwards easily through the upper part of the juice outlet grid hole due to the low pressure born by the fruit juice, and the fruit juice at the bottom of the squeezing barrel can be blocked and limited by the matching convex ring and the juice outlet gap after being squeezed out of the juice outlet grid hole at the lower part, so that the purity of the fruit juice can be ensured.

It should be noted that the juice outlet grid hole may be stepped in the axial direction, that is, the width of the upper part of the juice outlet grid hole is narrower, and the width of the lower part is wider. Like this, on the one hand, make things convenient for the injection moulding who goes out the juice bars hole, can avoid the pomace to follow the direct outside discharge in juice bars hole upper portion simultaneously, and the juice bars hole of going out of lower part broad is then favorable to promoting juice speed and efficiency, avoids appearing pomace blocking phenomenon, facilitates the washing after the use.

Further, we can set up the position ring muscle 42 along circumference extension at recipient lower part lateral wall, and the position ring muscle is located between the adjacent juice bars hole, when recipient installation location cooperates the bulge loop in the time, the position ring muscle pastes and leans on cooperation bulge loop inside wall, thereby make recipient's lower part obtain reliable central location, and form a radial juice gap of going out between recipient lateral wall and cooperation bulge loop inside wall, the juice accessible radial juice gap that outwards flows through going out juice bars hole upwards flows, through the outside output of juice mouth after crossing the top edge of cooperation bulge loop. The radial juice outlet gap is beneficial to the precipitation and filtration of trace fruit residues mixed in the upward flowing fruit juice.

As mentioned above, the inner side wall of the matching convex ring is provided with a demoulding slope, and preferably, the positioning ring rib can be arranged at the position, close to the lower end face, of the extrusion container, so that a sufficient matching gap is formed between the outer diameter of the positioning ring rib and the inner diameter of the opening of the matching convex ring. When the extrusion cylinder is inserted and matched into the matching convex ring from top to bottom, collision interference between the positioning ring rib and the opening of the matching convex ring can be avoided, and the juice extractor is convenient to install and use.

As a third preferred scheme, as shown in fig. 5, 6 and 7, a plurality of juice outlets 25 uniformly distributed in the circumferential direction and extending upward to the upper end surface may be provided on the inner side wall of the engaging convex ring, so as to form engaging protrusions 26 between adjacent juice outlets. In addition, a fitting notch 43 is provided at the lower end of the container corresponding to the fitting projection. When the extruding container is installed and positioned in the juice collecting cavity, the lower end of the extruding container is supported by the inner side wall of the matching convex ring, so that the lower end of the extruding container is reliably centrally positioned, meanwhile, an axial juice outlet gap is formed between the two side edges of the matching convex block close to the extruding container and the two side edges of the matching notch close to the matching convex ring, and a juice outlet recess forms a radial juice outlet gap between the extruding container and the matching convex ring. The juice in the recipient flows outward through axial juice gap earlier, then upwards flows in radial juice gap to cross the upper edge of cooperation bulge loop and outwards flow, finally outwards export through the juice mouth.

It should be noted that the juice outlet recess is a certain distance away from the bottom wall of the juice collecting cavity, so that the lower end edge of the extrusion container with the matching notch is reliably positioned at the bottom of the inner side wall of the matching convex ring, and the matching notch can be approximately rectangular, so that the matching notch has a larger width, which not only facilitates the molding formation of the extrusion container, but also facilitates the cleaning after use. And the width of the matching notch is preferably larger than or equal to the width of the matching lug, so that axial juice outlet gaps are formed on two sides of the matching notch.

Preferably, we can control the depth a of the juice-extracting recess in the following range: a is more than or equal to 0.1mm and less than or equal to 0.5mm, so that a proper radial juice outlet gap is formed between the extruding cylinder and the matched convex ring, the juice outlet speed and the juice outlet efficiency are favorably improved, and meanwhile, the juice can be effectively precipitated and filtered for the second time, so that the purity and the taste of the juice are improved.

As a fourth preferred alternative, as shown in fig. 8 and 9, an integral mating protrusion 27 may be provided on the upper edge of the mating protrusion, and a corresponding opening 44 may be provided at the lower end of the container corresponding to the mating protrusion. When the upper cover and the extruding cylinder are positioned and installed at the opening at the upper part of the juice collecting cavity, the lower end of the extruding cylinder is supported by the inner side wall of the matching convex ring, so that the lower end of the extruding cylinder is reliably positioned at the center, the opening at the moment just corresponds to the matching convex tooth, and an axial juice outlet gap is formed between the two side edges of the matching convex tooth close to the opening and the two side edges of the opening close to the matching convex tooth.

Because the cooperation bulge loop at this moment mainly plays the effect that makes the recipient lower extreme radially support and center location, consequently, we can reduce the height of cooperation bulge loop as far as possible, reduce the height of cooperation dogtooth simultaneously, both can ensure the intensity of cooperation bulge loop and cooperation dogtooth, can conveniently form out the juice gap again, and the juice can be followed and juice gap is direct outwards flowed to be favorable to shortening the flow path of juice, promote out juice speed and efficiency.

It should be noted that, since the juice outlet gap is located above the matching convex ring, the juice collected at the bottom of the juice collecting cavity needs to flow out from the juice outlet gap under the extrusion action of the screw, and most of the tiny pomace mixed in the juice is deposited at the bottom of the juice collecting cavity.

Finally, we can control the juice gap b in the following range: b is more than or equal to 0mm and less than or equal to 0.3mm, so that the good filtering effect of the juice can be ensured, the purity and the taste of the juice are improved, the juice extractor can have proper juice outlet speed and juice outlet efficiency, and the juice is prevented from being discharged outwards along with the pomace to reduce the juice outlet rate. When b < 0mm, it means that the matching convex tooth and the opening, and the matching convex block and the matching notch are partially overlapped in the circumferential direction, and smooth discharge of juice can be influenced at the moment, so that the juice discharging speed and efficiency are reduced, and then part of juice is mixed in the pomace and is discharged outwards together, and the juice discharging rate is reduced. When b is more than 0.3mm, the filtering effect of the juice outlet gap is influenced, so that the purity of the juice is reduced, and the taste of the juice is influenced.

It should be noted that in order to facilitate the radial fit between the container and the mating collar, a certain clearance fit tolerance is provided between the container and the mating collar. The juice outlet gap here includes an axial juice outlet gap and a radial juice outlet gap, and the juice outlet gap b in the axial juice outlet gap is the width in the circumferential direction. Therefore, when b =0mm, the tolerance of the fit between the container and the fitting collar constitutes the minimum juice outlet gap.

Example two:

as shown in fig. 10, a juicer having a simple structure is different from embodiment 1 in that the upper end of a squeezing barrel 4 is connected with an upper cover 12 to form an integral component, a circular matching convex ring 23 which is formed by integrally protruding is arranged at the bottom of a juice collecting cavity 2, and the lower end of the squeezing barrel is inserted and matched in the matching convex ring, so that a juice outlet gap 231 for allowing juice to flow out is formed between the lower end of the squeezing barrel and the matching convex ring. It should be noted that the juice outlet gap includes a bottom gap 232 formed between the lower end surface of the container and the bottom wall of the juice collecting cavity, and a side gap 233 formed between the outer side wall of the lower portion of the container and the inner side wall of the matching convex ring, and the bottom gap is communicated with the side gap. When the juice enters the side gap after being filtered through the bottom gap, the juice can flow upwards in the side gap, flows outwards beyond the upper edge of the matching convex ring and is finally output outwards through the juice outlet. When fruit juice flows upwards in the side gap, a small amount of tiny pomace mixed in the fruit juice can be automatically deposited at the bottom of the side gap under the action of gravity, so that the purity and the taste of the fruit juice are favorably improved.

In addition, the side gap should be unanimous with the bottom gap, perhaps, the side gap is greater than the bottom gap, ensures the filtering action to fruit juice through the bottom gap on the one hand, and on the other hand is favorable to the fast flow of fruit juice, and then improves out juice speed.

Preferably, the upper cover comprises an outer cover 121 and an inner cover 122 disposed inside the outer cover, the container and the inner cover are formed into a unitary member by injection molding, and the outer cover and the inner cover are fixedly connected by an ultrasonic welding process. Like this, integrated into one piece's inner cup and recipient can simplify technology, convenient processing, and ultrasonic bonding's enclosing cover and inner cup then are favorable to increasing welding area, and then improve welding strength, ensure the reliability of connecting. It will be appreciated that corresponding locating formations may be provided between the outer and inner caps to ensure accuracy in the location between the outer and inner caps and hence the relative position between the upper cap and the container. When the upper cover is covered on the juice collecting cavity, the matching clearance between the extrusion container and the screw rod as well as the matching convex ring can be ensured.

The rest of the structure and the scheme of the embodiment are the same as those of the first embodiment, and are not described herein too much.

Other embodiments of the present invention than the preferred embodiments described above will be apparent to those skilled in the art from the present invention, and various changes and modifications can be made therein without departing from the spirit of the present invention as defined in the appended claims.
