Description

Juicing filter, juicing filter assembly, juicer and juicing method

Technical Field

The invention relates to the field of juicing, in particular to a juicing filter, a juicing filtering component, a juicer and a juicing method.

Background

A juicer is a tool in daily life, and is capable of juicing fruits and other objects. The main types of juicers are two, one is a centrifugal juicer and the other is an extrusion type juicer, and no matter which juicer is used, fruit can be usually filtered by a filter screen to obtain juice with better taste. Taking a squeezing juicer as an example for explanation, the general working principle is as follows: firstly, the fruit needs to be cut into smaller pieces, then the fruit is pushed into a squeezing cavity, the juice is squeezed under the squeezing action of a screw, the squeezed juice flows to the outside of the juicer from an outlet, and a filter screen is generally arranged at the outlet position so that the juice meeting the specification of the filter screen can flow out, thereby intercepting juice particles with the specification exceeding the expected specification, so that the juice particles are left in the squeezing cavity to be squeezed continuously.

The degree of thickening of the juice to achieve a better mouthfeel is not necessarily the same for different fruits, i.e. with the same size of sieve, it is possible for kiwi juice to be in a better mouthfeel state and for apple juice to be in an excessively thickened mouthfeel state. In addition, the taste preferences of different consumers for the same juice may also be different. In order to meet these demands, there are two main approaches currently adopted by manufacturers of juice extractors, namely, one approach is to provide a juice extractor with a plurality of filters of different specifications, and a consumer can freely select a filter meeting the demand to be installed in an installation cavity of the juice extractor, and the other approach is to provide a juice extractor with a filter, but a filter screen of the filter can be replaced by a filter of different specifications. The problem that such design brings is that on one hand, the cost of the juice extractor is increased, which reduces the competitiveness in the market, and on the other hand, the consumer needs to stock a plurality of sizes of filters or strainers for selecting the proper size when using, and in the process, some sizes of strainers or strainers may be lost due to improper storage, and finally the consumer may use the same.

The juicer is adapted to juic material, such as fruit, into juice. The juice extractor can be conveniently operated to provide juice of different consistencies or different particle grades, according to the needs of the user.

In detail, the juice extractor comprises a base 10, a squeezing rod 20 and a juice filtering assembly 100, wherein the squeezing rod 20 is used for squeezing materials, the juice filtering assembly 100 is used for filtering the materials squeezed into juice to obtain juice meeting the expected specification, the base 10 is suitable for providing a mounting position, and the base 10 is suitable for providing power for the squeezing rod 20. The base 10 may have a built-in motor and a power source, but it is understood that the base 10 may also use a power source other than the power source to provide power for the pressing rod 20.

The juicing and filtering assembly 100 comprises the juicing filter 30 and a mounting body 40, wherein the juicing filter 30 is mounted on the mounting body 40, the mounting body 40 comprises a mounting shell 41 and a squeezing head 42, wherein the mounting shell 41 is mounted on the stand 10, the mounting shell 41 forms a mounting cavity 410, a feeding hole 401, a discharging hole 402 and a mounting hole 403, the feeding hole 401, the discharging hole 402 and the mounting hole 403 are respectively communicated with the mounting cavity 410, and the squeezing head 42 is suitable for being mounted at the position of the mounting hole 403 of the mounting shell 41.

The pressing bar 20 is mounted to the housing 10 and is drivable to be rotatably mounted to the housing 10.

The juicing filter 30 comprises a supporting shell 31 and at least two filtering parts 32, wherein each filtering part 32 is respectively arranged on the supporting shell 31, the supporting shell 31 surrounds and forms a containing cavity 310, and the filtering parts 32 are arranged at the position of the openings of the containing cavity 310. The number of the filter portions 32 may be two, three, four or more, the sizes of the filter pores of different filter portions 32 may be different, or the arrangement and density of the filter pores may be different to satisfy different tastes of users. In the present embodiment, the number of the filter portions 32 is illustrated as three. When the number of the filter parts 32 is three, three filter parts 32 may be arranged around the pressing rod 20 and the sizes of the three filter parts 32 may be the same and uniformly arranged around the pressing rod 20. In addition, the juice extracting filter 30 and the mounting housing 41 are mounted by means of the three filter portions 32, and the contact positions of the three filter portions 32 and the mounting housing 41 can form a stable triangular structure, so that the juice extracting filter 30 is stably mounted on the mounting housing 41, and the juice extracting filter 30 is prevented from being displaced when the pressing rod 20 rotates. The filter holes of the filter part 32 may be circular, and when the filter holes are circular, the diameter thereof may range from 1.5mm to 5 mm.

The pressing rod 20 of the juicer is arranged to extend outwardly from the housing 10 and to the receiving cavity 310 formed by the support housing 31. The mounting body 40 forms a mounting cavity 410, wherein the pressing bar 20 and the juicing filter 30 are respectively received in the mounting cavity 410. During the operation of the juice extractor, material is fed into the mounting cavity 410 of the mounting body 40 and squeezed between the pressing lever 20 and the support housing 31 of the juice extractor 30, and as the pressing lever 20 rotates, the material between the pressing lever 20 and the support housing 31 of the juice extractor 30 is squeezed to extract juice.

Further, the mounting body 40 has a feed port 401 and a discharge port 402, wherein the feed port 401 is configured for material to enter, and the discharge port 402 is configured for material to flow out. The feed inlet 401 and the discharge outlet 402 are respectively communicated with the installation cavity 410.

After the material is squeezed into juice via the squeezing rod 20 and the juicing filter 30, the material juice exits the juicer through the discharge outlet 402. One of the filter portions 32 of the juice extractor 30 is arranged at the outlet 402 of the mounting body 40 to be filtered before the juice leaves the extractor, on the one hand to filter out part of the material residues and on the other hand to retain material having a size larger than the size of the filter portion 32. It is worth mentioning that the material trapped in the filtering portion 32 of the juice extractor 30 can be returned to between the squeezing bar 20 and the supporting shell 31 of the juice extractor 30 by the squeezing bar 20 to be squeezed again.

Further, the juicing filter 30 has a fixed state in which the juicing filter 30 is mounted to the mounting body 40 and is not carried by the pressing rod 20 to follow the movement of the pressing rod 20 when the pressing rod 20 rotates, and an optional state. In other words, in the secured state, the juicing filter 30 is captively mounted to the mounting body 40, and the selected filter portion 32 can be held in alignment with the outlet 402. In the optional state, the three filter portions 32 of the juicing filter 30 can be selected to determine which filter portion 32 is aligned with the outlet 402 of the mounting body 40. In detail, in the alternative state, the juicing filter 30 can be activated, for example rotated, to select which of the filter portions 32 is adapted to be aligned with the outlet 402. The three filter portions 32 of the juicing filter 30 are arranged on the support housing 31 and around the pressing rod 20, with the discharge port 402 of the mounting body 40 located at one side of the pressing rod 20. The switching of different taste modes of the juicer can be achieved by rotating the juicing filter 30 to change the relative positions of the filter and the discharge hole 402.

In such a way, the juice extractor can provide material juices with different tastes by using the same juicing filter 30, and does not need to be provided with a plurality of juicing filters 30 or replace filter screens on the same juicing filter 30. For manufacturers, the manufacturing cost is saved, and for consumers, the use is more convenient.

It is worth mentioning that when the filter portion 32 of the juicing filter 30 is selected, the juicing filter 30 can be held in a fixed position so that the selected filter portion 32 is aligned with the outlet 402, while the entire juicing filter 30 can be held fixed so as not to be entrained by the squeezing rod 20 to move.

In detail, the installation housing 41 of the juicer has the installation cavity 410 and a feeding channel 420, wherein the feeding channel 420 is communicated with the installation cavity 410, the feeding hole 401 is communicated with the feeding channel 420, and the material enters the feeding channel 420 from the feeding hole 401, then enters the installation cavity 410, is squeezed between the squeezing rod 20 and the supporting housing 31 of the juicing filter 30, and finally leaves the juicer after passing through the filtering part 32 and the discharging hole 402 in sequence.

The mounting body 40 includes the mounting housing 41 and the extrusion head 42, wherein the mounting housing 41 is formed with the feed port 401, the discharge port 402, and the feed passage 420, and the mounting housing 41 and the extrusion head 42 together form the mounting cavity 410. The extrusion head 42 is mounted to the mounting housing 41 and is configured to be detachably mounted to the mounting housing 41. It should be understood by those skilled in the art that the structural arrangement of the mounting body 40 is illustrated herein, and the mounting body 40 of the juice extractor of the present invention is not considered to be limited to the above description.

Further, the mounting housing 41 of the mounting body 40 is mounted to the machine base 10, and the mounting housing 41 is located between the extrusion head 42 and the machine base 10, wherein the extrusion rod 20 extends outwards from the machine base 10 through the mounting housing 41, extends to the extrusion head 42 and is inserted into the extrusion head 42, and the extrusion rod 20 is limited by the extrusion head 42 to ensure concentricity when the extrusion rod 20 rotates.

The support housing 31 of the juicing filter 30 has a first end 311 and a second end 312, wherein the first end 311 is arranged close to the mounting housing 41 of the mounting body 40, and the second end 312 is arranged close to the squeezing head 42 of the mounting body 40, wherein the filter part 32 is mounted to the first end 311 of the support housing 31 and to the mounting housing 41 of the mounting body 40.

Further, referring to fig. 5, the inner wall of the mounting housing 41 of the mounting body 40 is recessed to form a recovery groove 430, wherein the inner wall forming the recovery groove 430 is lower than other portions of the inner wall of the mounting housing 41, so as to facilitate the juice to collect at the position of the recovery groove 430 of the mounting housing 41 of the mounting body 40. The discharge hole 402 is disposed at the mounting housing 41 of the mounting body 40 and at the position of the recovery groove 430, so that the juice collected at the position of the recovery groove 430 can smoothly leave the juice extractor through the discharge hole 402.

At least a portion of the inner wall of the mounting housing 41 of the mounting body 40 is recessed to form at least one retaining groove 440, wherein the retaining groove 440 and the juicing filter 30 mate to limit the movement of the juicing filter 30. In detail, in the present embodiment, the number of the filter parts 32 of the juice extractor 30 is three, the number of the limiting recesses 440 of the mounting case 41 of the mounting body 40 is three, and each of the filter parts 32 corresponds to one of the limiting recesses 440. The stopping groove 440 limits the rotation of the juice filter 30. It is understood that the number of the limiting recesses 440 may be one, two or more, which is only an example.

Further, in the present embodiment, the adjacent filtering portions 32 of the juicing filter 30 are provided to be arranged at intervals. The retaining grooves 440 corresponding to the filter part 32 are also provided in a spaced arrangement, and the mounting case 41 of the mounting body 40 forms a retaining projection 450 between the adjacent retaining grooves 440, wherein the retaining projection 450 restricts the filter part 32 from rotating from one retaining groove 440 toward the other retaining groove 440. The limit projection 450 includes a first portion limit projection 451 and a second portion limit projection 452, wherein the first portion limit projection 451 extends beyond the second portion limit projection 452 and the second portion limit projection 452 is located outside to contact the juice filter 30 with respect to the first portion limit projection 451 when the juice filter 30 is mounted to the mounting housing 41.

The side circumference of the first partial limit projection 451 extends to the side circumference of the second partial limit projection 452, and the side circumference of the first partial limit projection 451 is configured to be outwardly protruded, and for the whole limit projection 450, the outer circumference thereof is configured to be a "convex" structure. The two filter parts 32 can be respectively inserted into two sides of the convex structure.

It is understood that the circumferential rotation of the juice extractor 30 is restricted by the mounting case 41 of the mounting body 40, and the radial movement of the juice extractor 30 is restricted by the mounting case 41 of the mounting body 40 and the pressing head 42. The squeezing head 42 is detachably attached to the attachment housing 41, and when the squeezing head 42 is removed from the attachment housing 41 of the attachment body 40, the juice extractor 30 can be removed from the attachment housing 41 of the attachment body 40. If the user wishes to obtain a different taste, he can choose to rotate the extracted juicing filter 30 so that, after the juicing filter 30 has been remounted in the mounting casing 41, a new filter portion 32 can be aligned with the outlet 402 to obtain a different taste of the juice.

The juicing filter 30 not only plays a role in filtering, but also assists the squeezing rod 20 in squeezing materials. In detail, the support housing 31 of the juicing filter 30 is provided to be funnel-shaped or tapered, and the aperture of the support housing 31 is provided to be tapered from the first end 311 toward the second end 312. When the pressing rod 20 is continuously rotated to push the material from the first end 311 position to the second end 312 position of the supporting shell 31, the aperture of the supporting shell 31 is continuously reduced, so that the material is suitable for being pressed into a smaller volume to obtain the juice.

In more detail, the supporting housing 31 is disposed to be inclined, and when the supporting housing 31 is in a horizontal use state, the material at the position of the second end 312 of the supporting housing 31 automatically moves toward the position of the first end 311 of the supporting housing 31 by gravity, so that the material juice automatically flows to the first end 311 of the supporting housing 31 and then is recovered to the filtering portion 32 for filtering.

It is worth mentioning that, since the juice extractor utilizes the squeezing and grinding action between the squeezing rod 20 and the juice extracting filter 30 to extract juice from the material, when the number of the filtering portions 32 exceeds one and is arranged around the squeezing rod 20, it is beneficial to increase the probability that the material is squeezed at the position of the filtering portion 32, so that the material juice can be directly squeezed out through the filtering portion 32, and therefore, the probability of friction between the material juice and the squeezing rod 20 is reduced, and the influence of heat generated by friction during the squeezing process on the taste of the material juice is reduced.

For example, the three filter portions 32 in this embodiment can press and grind the material by means of the pressing rods 20, so that at least a portion of the juice can be squeezed out without entering the receiving cavity 310 of the supporting housing 31. The feed juice may exit the juicer under gravity through the filter portion 32 aligned with the spout 402.

It should be noted that, in the present embodiment, the filtering portion 32 includes a mounting frame 321 and a filter 322, the filter 322 is mounted on the mounting frame 321, and the filter 322 is made of a metal material. By the strainer 322 disposed around the extruding rod 20, heat generated from the extruding rod 20 during the rubbing process is easily dissipated through the filtering portion 32 to reduce the influence on the taste of the material juice. It will be appreciated by those skilled in the art that fruit is readily oxidized in air, and that temperature has a greater effect on the rate of oxidation.

In the prior art, only one filter part 32 is arranged and the filter part 32 is aligned with the discharge port 402, in this embodiment, three filter parts 32 are arranged on the support housing 31 and one filter part 32 is aligned with the discharge port 402, and heat generated during the pressing process can be dissipated outwards through the holes formed in the three filter parts 32 on one hand and the metal material forming the filter screen 322 on the other hand. In addition, since the material juice is mainly filtered by one of the filter units 32 under the action of gravity, for the filter unit 32 which needs to be filtered, the other two filter units 32 can play a role of auxiliary heat dissipation, so as to reduce the temperature of the environment where the filter unit 32 which needs to be filtered is located.

In this embodiment, the filter screen 322 may be detachably mounted on the mounting rack 321, or the mounting rack 321 is integrally formed on the surface of the filter screen 322, and the mounting rack 321 may be made of a food-grade resin material or a metal material. The filter part 32 may be integrally formed or may be separately formed. Further, the filter part 32 is designed to have a concave middle and convex two sides. When the filter portion 32 is aligned with the spout 402, juice from the material is advantageously collected in the middle recessed filter portion 32.

In one embodiment of the present invention, the juice filter 30 is manufactured by integrally forming the juice filter 30 of a predetermined structure by a molding die. For example, a plurality of the filter meshes 322 are disposed at a predetermined position of a molding die, and a molding material is injected into the molding die, thereby integrally connecting the plurality of the filter meshes 322 to the mounting frame 321. In another embodiment of the present invention, a plurality of the filter screens 322 are fixed inside the mounting frame 321. That is, after the main body portion of the juice extracting filter 30 is manufactured and molded by a mold, a plurality of the filter nets 322 are further installed to the main body portion.

In more detail, the filter part 32 includes a first partial filter part 323 and a second partial filter part 324, wherein the second partial filter part 324 is located between the first partial filter part 323 and the support housing 31, and the first partial filter part 323 is configured to extend to be contracted outward from the second partial filter part 324, thereby forming a space between the adjacent filter parts 32. The second partial filtering portions 324 are provided as wings protruding outward to collect the juice as much as possible at the wings.

When the juice extractor 30 is inserted into the mounting housing 41, the first partial filter portion 323 of the filter portion 32 firstly enters the mounting housing 41, wherein the filter portion 32 has an outer peripheral edge 325, the outer peripheral edge 325 is configured as a convex arc structure, and the first partial filter portion 323 can slide into the limit groove 440 of the mounting housing 41 very smoothly along the convex arc protruding position of the convex arc structure of the outer peripheral edge 325. The contour of the retaining groove 440 is designed to match the outer perimeter 325 of the filter portion 32, and is also a "convex" arc-shaped contour, so that the user does not need to align the filter portion 32 and the corresponding retaining groove 440 precisely during installation, and can install both smoothly by virtue of the contour design of the two. In addition, the filter part 32 and the support housing 31 may be integrally formed, and the entire support housing 31 may be made of a metal material or a plastic material. The filter house 32 and the support housing 31 may also be of a split design.

Further, in the prior art, the outer periphery of the filter part 32 is designed to be convex in a circular arc shape, similar to an elliptical circular arc, so that the installation of the filter part 32 and the installation case 41 can be completed with a small force along the arc during the installation process. In this embodiment, the outer periphery 325 of the filter part 32 forms an arc-shaped "convex" structure, and the limit groove 440 forms a matching arc-shaped "concave" structure, so that the filter part 32 needs to exert a larger force when entering the limit groove 440, and simultaneously the filter part 32 needs to exert a larger force when being pulled out, in other words, the design of the filter part 32 can facilitate the filter part 32 to be more stably mounted on the mounting housing 41.

In more detail, the outer circumferential edge 325 of the filter portion 32 includes an end circumferential edge 3251, two concave side circumferential edges 3252 and two bottom circumferential edges 3253, wherein the two side circumferential edges 3252 are distributed on two sides of the end circumferential edge 3251, the two bottom circumferential edges 3253 respectively extend to the two side circumferential edges 3252, and the two sides of the side circumferential edge 3252 are the end circumferential edge 3251 and the bottom circumferential edge 3253 respectively.

The side peripheral edge 3252 extends between the end of the end peripheral edge 3251 and the end of one of the bottom peripheral edges 3253 and is configured to be concave and convex at a corresponding position of the limiting groove 440, so that during the insertion of the filter part 32, after the end peripheral edge 3251 of the outer peripheral edge 325 enters the limiting groove 440, the side peripheral edge 3252 needs to be partially pushed in along the convex limiting groove 440, and thus a large force is needed, and similarly during the extraction. In this way, the two are firmly combined.

Further, the pressing rod 20 is provided as a protrusion to press the material. In the present embodiment, the pressing rod 20 is embodied as a threaded rod, the surface of which is provided with a thread. The pressing rod 20, which is threaded, facilitates the pressing of the material into smaller volumes when the pressing rod 20 is rotated to press the material between the pressing rod 20 and the support housing 31 of the juice filter 30. In addition, at least part of the surface of the pressing rod 20 can contact the filtering part 32 at the position of the filtering part 32 of the juicing filter 30 so as to scrape off material residues remained at the position of the filtering part 32 during the rotation process, thereby reducing the possibility of blockage at the position of the filtering part 32.

Still further, with reference to fig. 4 in particular, the support housing 31 of the juicing filter 30 is provided with a plurality of guiding ribs 33, wherein the guiding ribs 33 extend between the first end 311 and the second end 312 of the support housing 31 and can be arranged close to the second end 312 of the support housing 31 for enhanced squeezing of material or material slag for juice between the material or material slag, i.e. the material or material slag that is about to leave the support housing 31. The guide rib 33 protrudes from the inner wall of the support housing 31 to guide the inside of the accommodating chamber 310. The adjacent guide ribs 33 are arranged at intervals, and may be arranged side by side or staggered. The supporting housing 31 of the juicing filter 30 is provided with at least one grinding ring 34, the number of the grinding rings 34 can be one, two, three or more, wherein the grinding ring 34 is arranged around the inner wall of the supporting housing 31 to cooperate with the pressing rod 20 to grind materials when the pressing rod 20 presses the materials. In this embodiment, the guide ribs 33 are disposed adjacent to the first end 311 of the support housing 31, and the grinding ring 34 is disposed adjacent to the second end 312 of the support housing 31.

The extending direction of the guide ribs 33 of the support housing 31 is arranged to be staggered with the screw thread of the pressing rod 20 to facilitate grinding of the materials, and the extending direction of the grinding ring 34 of the support housing 31 is arranged to be staggered with the screw thread of the pressing rod 20 to facilitate grinding of the materials. In this embodiment, the guide ribs 33 of the support housing 31 are arranged in an axial arrangement, and the grinding ring 34 is arranged in a circumferential arrangement with respect to the rotational axis of the pressing rod 20.

The guide ribs 33 and the grinding ring 34 may be made of a metal material or a plastic material, and may be integrated with the support housing 31 or may be separately disposed.

The support housing 31 of the juicing filter 30 is further arranged with a juice discharge portion 35, wherein the filtering portion 32 and the juice discharge portion 35 are arranged at the front end and the rear end of the support housing 31, respectively. The juice discharging part 35 may be integrally formed with the supporting housing 31, or the juice discharging part 35 and the supporting housing 31 may be of a split design.

When the juice extractor is used for extracting juice, the squeezing rod 20 and the supporting shell 31 of the juice extracting filter 30 are matched for extracting juice, the crushed material residues and the material juice continue to advance under the pushing and squeezing action of the squeezing rod 20, part of the crushed material residues and the crushed material juice leave the juice extractor through the filter part 32 at the front end, part of the crushed material residues and the crushed material juice are pushed to the juice discharging part 35, and the juice passes through the juice discharging part 35 and then enters between the filter part 32 and the mounting main body 40 and then flows to the position of the discharge hole 402 to leave the juice extractor. The material slag continues to be pushed by the extrusion ram 20 to the extrusion head 42 position to be collected.

In detail, the juice discharging part 35 is formed with a strip-shaped gap, so that juice can flow out smoothly and the juice discharging efficiency is high compared with the mesh-shaped filtering structure of the filtering part 32. In the present embodiment, the strip-shaped slits of the juice discharge portion 35 are arranged along the axial direction. Alternatively, the strip-shaped slits of the juice discharge portion 35 may also be arranged circumferentially.

With the juicing filter 30, the filter portion 32 of the juicing filter 30 is positionally fixed to the mounting housing 41 of the mounting body 40, the juice discharge portion 35 of the juicing filter 30 is fastenably fixed to the squeezing head 42, and residue can be collected at the squeezing head 42.

For the material, the material in the preset size enters the feeding channel 420 of the mounting body 40 from the feeding hole 401, and then enters the mounting cavity 410. In the present embodiment, the installation chamber 410 is provided in a horizontal type, the feeding passage 420 is arranged in a vertical type, and the juicing filter 30 is arranged in the installation chamber 410 and is arranged in a horizontal type. It will be appreciated by those skilled in the art that the juicing filter 30 may be applied to horizontal juicing devices, as well as to vertical juicing devices.

In this embodiment, the material enters the installation cavity 410 through the space formed by the adjacent filter parts 32, and is then squeezed and ground by the squeezing rod 20 to produce juice. The juice can be filtered by the filter 32 at the front end or can be discharged by the juice discharging 35 at the rear end. The material residue may partially remain on the filter portion 32 and may be scraped off by the rotation of the extrusion rod 20, and most of the material residue is pushed toward the extrusion head 42 by the rotating extrusion rod 20.

When a user desires to obtain juices of different tastes, he or she may choose to remove the squeezing head 42 from the mounting housing 41 of the mounting body 40 and then the juice extractor 30. The juice filter 30 is then reinstalled with the other filter portion 32 aligned with the spout 402, and then the squeeze head 42 is installed. The juicer may be re-operative and provide juice of another flavor.

The juicer includes a packing 50, and the packing 50 is mounted to the mounting housing 41 before the pressing head 42 of the mounting body 40 is mounted to the mounting housing 41, so as to ensure a sealing degree between the mounting housing 41 and the pressing head 42 after the pressing head 42 is mounted to the mounting housing 41.

It is worth mentioning that the juice extractor filter 30 of the juice extractor further comprises a supplementary filter portion 36, wherein the supplementary filter portion 36 is arranged to the support housing 31. The supplementary filter 36 can perform a supplementary filtering function, and the filter 32 can be assisted by the supplementary filter 36 to filter at least part of the returned material juice during the process of pushing the material toward the juice discharging portion 35. The supplementary filter 36 has a plurality of through holes 320, wherein the through holes 320 are disposed at the support housing 31 of the juice filter 30.

It is to be noted that the supplementary filter portion 36 and the guide rib 33 are disposed oppositely, and the supplementary filter portion 36 and the guide rib 33 are disposed close to both ends of the support housing 31, respectively. When the material is squeezed at the position of the guide rib 33 to discharge the juice, the material juice can automatically flow towards the supplementary filter part 36 under the action of gravity, and the material juice is discharged in time.

The through holes 320 are arranged at intervals and have a predetermined size and dimension such that juice of the material in the receiving chamber 310 formed in the support housing 31 can pass through the through holes 320 and then exit the juice extractor through the discharge hole 402. In the present embodiment, the supplementary filter 36 is arranged corresponding to one of the filter portions 32, that is, the through holes 320 are arranged corresponding to one of the filter portions 32, and the size of the through holes 320 corresponds to the size of the filter holes of the filter portion 32, so that material juice of the same size can pass through the through holes 320 or the corresponding filter portions 32 when flowing along the inner wall of the juice extracting filter 30 under the action of gravity.

The size of the through holes 320 of the supplementary filter unit 36 and the size of the filter holes of the filter unit 32 may be the same or different. For example, when the size of the through hole 320 is smaller than the size of the filtering hole of the filtering portion 32, the supplementary filtering portion 36 can filter out the material juice with a fine taste first, so as to disperse the flow at the position of the filtering portion 32, thereby assisting the filtering.

By the filter part 32, the juice discharging part 35 and the supplementary filter part 36, the juice extractor can form multi-stage filtering for materials. After the material that cannot be filtered by the filter portion 32 passes through the supplementary filter portion 36, the material can be pushed forward by the rotation of the pressing rod 20. Material that cannot be filtered by the supplementary filter 36 can continue to be pushed forward until the juice drain 35 is in place. After passing through the juice extraction portion 35, a portion of the material may be filtered. In this process, due to the structural arrangement of the support housing 31, the positions of the juice discharging part 35, the supplementary filter part 36 and the filter part 32 are gradually lowered, so that the material juice which does not pass through the juice discharging part 35 can flow back along the support housing 31, the supplementary filter part 36 can be filtered, the filter part 32 can be filtered, and then the material can be sufficiently squeezed along with the movement of the squeezing rod 20 to discharge the juice as much as possible.

It is understood that the number of the supplementary filter portions 36 may be three, and are arranged to correspond to three of the filter portions 32, respectively. For example, the number of the through holes 320 may be plural and the support housing 31 surrounding the support housing 31 arranged in the juice filter portion 32 may be divided into three regions corresponding to three filter portions 32, and the size and density of the through holes 320 in each region may correspond to the respective filter portions 32.

For the juice extractor 30, three positions are provided for the exit of the material juice and the exit of the material residue with the material juice is limited as far as possible. One position is a front end position of the juicing filter 30, i.e., the filter portion 32 position, one position is a rear end position of the juicing filter 30, i.e., the juice discharge portion 35 position, and the other position is the support housing 31 position, i.e., the through hole 320 position.

For the material entering the juice extractor, the main juice outlet position is concentrated at the front of the juice extractor 30, in this embodiment, three filter parts 32 are arranged, the filter parts 32 not used for juice outlet can cooperate with the squeezing rod 20 to squeeze the material for juice outlet, and the through hole 320 of the support housing 31 in this embodiment can be used for juice outlet. The material pushed into the support housing 31 can be extracted from the juice through the through holes 320 in the support housing 31 without flowing back to the filter portion 32 or being pushed further to the juice discharge portion 35. With this arrangement, juice is squeezed out of the mounting body 40 and can be discharged as quickly as possible to leave the juicer, so that a user can obtain juice in a relatively quick time, and the deterioration of taste due to the juice being squeezed out of the mounting body 40 is reduced.

Further, in the present embodiment, a projected length ratio of the sieve 322 of the filtering portion 32 of the juice extracting filter 30 to the support case 31 in the rotation axis direction of the pressing rod 20 can be controlled to be less than 0.6. In the prior art, since the positions where juice can be taken out are mainly concentrated on one filter unit 32, the filter unit 32 needs to be made long in order to take out juice smoothly. In this embodiment, on the one hand, the number of the filter parts 32 may be two, three or more, and during the rotation of the pressing rod 20, in addition to one of the filter parts 32 that mainly produces juice, other filter parts 32 may also produce juice. On the other hand, juice can be extracted from the through holes 320 of the supplementary filter 36 disposed in the support housing 31, so that the requirement for the area size of the filter screen 322 of the filter 32 is reduced, which is beneficial to the miniaturization of the juicer. If the ratio of the projected lengths in the direction of the rotation axis of the sieve 322 of the filter part 32 and the pressing rod 20 of the support housing 31 exceeds 0.6, for example, 0.7, it is found that the filtering capacity of the juice extractor 30 is significantly reduced in the same size. If the same filtering capacity is to be achieved, the size of the juice extractor 30 needs to be enlarged, thereby not contributing to the miniaturization of the whole juice extractor.

The intervals between the adjacent filter portions 32 may be the same. It will be appreciated by those skilled in the art that the number of filter portions 32 may be two, three, four or more.

Referring to fig. 11A and 11B, another embodiment of the juicing filter 30 according to the above preferred embodiment of the present invention is illustrated. In the present embodiment, the juice extracting filter 30 includes three filter portions 32, and the adjacent filter portions 32 are integrally formed. In the above embodiment, the adjacent filter units 32 are kept at a constant interval.

In the present embodiment, the filter screen 322 of the filter part 32 is implemented as a whole, and the size of the filter holes of the filter screen 322 may be arranged differently in regions to form the filter screens having different filter specifications, based on the filtering requirement.

According to another aspect of the present invention, there is provided a juicing method, wherein the juicing method comprises the steps of:

by driving the pressing rod 20 to rotate so as to press the material with the juicing filter 30 to be juiced and the material is pushed forwards, at least two filtering parts 32 are arranged around the pressing rod 20 and one filtering part 32 is arranged below the pressing rod so as to filter the juice which automatically flows back along the supporting shell 31 of the juicing filter 30.

According to one embodiment of the present invention, the pressing rod 20 scrapes the filter part 32 during rotation to remove at least part of the material residue attached to the filter part 32.

According to an embodiment of the present invention, the juice is at least partially discharged through the through holes 320 of the support housing 31 during the backflow toward the filter part 32.
