The consumer needs to precisely align the plurality of circumferentially disposed projections and recesses in order for the screen cartridge to be installed on the juice extractor cup. Due to the requirement of the protrusion and the groove to be matched accurately, the consumer has the problem of difficult installation, which affects the use experience of the consumer.

Fig. 1 is a schematic structural diagram of a juicer according to an embodiment of the present invention. Fig. 2 and fig. 3 are schematic diagrams of a juice extracting structure of a juice extractor according to an embodiment of the present invention. Referring to fig. 2 to 4, the juice extracting structure includes a juice extracting cup 100 and a screen cartridge 200 that may be located within the juice extracting cup 100. The bottom of the screen cartridge 200 is provided with an annular groove 201 (see fig. 4), and the inner bottom wall of the juice extracting cup 100 is provided with an annular protrusion 101. The annular protrusion 101 is receivable within the annular recess 201 such that installation of the screen cartridge 200 and juice extractor cup 100 is facilitated by the regular alignment of the annular protrusion 101 with the annular recess 201, providing a consumer experience.

Similarly, please refer to fig. 1, a juicer includes a main body 500 and a juice squeezing structure of the juicer. Juice extraction cup 100 detachably installs on host computer 500, and host computer 500 is equipped with drive arrangement, and drive arrangement is direct or indirect and is connected with strainer section of thick bamboo 200, and drive arrangement is used for driving strainer section of thick bamboo 200 rotatory to drive strainer section of thick bamboo 200 rotatory, make the fruit vegetables that are located strainer section of thick bamboo squeezed, generate residue and juice. In this stock machine, the installation of filter screen section of thick bamboo 200 and juice extraction cup 100 combines and only establishes through the alignment cover of regular annular protrusion 101 and annular groove 201, and the consumer of being convenient for installs, provides the consumption and uses experience.

Wherein the annular protrusion 101 can be snapped into the annular groove 201 at any angle of 360 degrees.

Specifically, with reference to fig. 4, when the annular protrusion 101 is received in the annular groove 201, a gap is formed between the inner wall of the annular groove 201 and the annular protrusion 101. An elastic material member 300 is installed in the gap. After the filter screen cartridge 200 is snapped into the juice extractor cup 100, the bottom of the juice extractor cup 100 is substantially flush with the bottom of the filter screen cartridge 200, and the inner wall of the annular groove 201 is spaced from the annular protrusion 101, i.e., the radial width of the annular groove 201 is greater than the width of the annular protrusion 101. An elastic material member 300 is installed in the gap.

In the juice squeezing structure of the juice extractor, the fruits and vegetables are squeezed in the filter screen cylinder 200 to generate residues and juice. Wherein, the mesh of juice accessible strainer section of thick bamboo 200, and the mesh of residue can not pass through strainer section of thick bamboo 200, simultaneously, because install elastic material 300 in the clearance between annular groove 201 and the annular bulge 101 under the assembled condition, then the residue can contradict elastic material 300 after getting into the clearance, and receive in elastic material 300's reaction force pushed back strainer section of thick bamboo 200, lead to the residue can not pass through this clearance, can not sneak into in the juice that sees through strainer section of thick bamboo 200, realize the thorough separation of juice sediment, thereby improve the quality and the taste of fruit juice.

Referring to fig. 5 and 6, the strainer cartridge 200 divides the interior cavity of the juice extracting cup 100 into a juice squeezing space 102 and a juice storage space 103. The inside of the sieve cylinder 200 forms a juice squeezing space 102, and a juice storage space 103 is formed between the outer wall of the sieve cylinder 200 and the inner side wall of the juice extracting cup 100. Furthermore, the juice extracting cup 100 is provided with a juice outlet 104 and a residue outlet 105, the juice outlet 104 is communicated with the juice storing space 103, the residue outlet 105 is communicated with the juice squeezing space 102, so that the juice can enter the juice storing space 103 and finally reach the outside of the juice extracting cup 100 through the juice outlet 104 to be collected and drunk, and the residue is retained in the screen cylinder 200 and finally discharged to the outside of the juice extracting cup 100 through the residue outlet 105.

It will be appreciated that in other embodiments, the strainer cartridge 200 may be fastened to the juice extractor cup 100 by providing an annular protrusion 101 on the bottom of the strainer cartridge 200 and an annular recess 201 on the inner bottom wall of the juice extractor cup 100.

Wherein, the elastic material 300 can be a rubber, a plastic or an elastic structure. A juice outlet 104 and a residue outlet 105 are optionally provided at the bottom of the juice glass 100. The filter screen cylinder 200 is of an open structure at the upper and lower ends. The meshes of the strainer cartridge 200 are small enough so that juice squeezed from the food material at the time of cooking is introduced into the juice storing space 103 through the meshes, while isolating the residue left after squeezing in the juice squeezing space 102.

Specifically, referring to fig. 2 to 4, the gap is defined by the groove wall of the annular groove 201, the annular protrusion 101, and the inner bottom wall of the juice extracting cup 100 close to the annular protrusion 101. The elastomeric member 300 may be installed in the gap in a variety of ways, and the elastomeric member 300 may be selectively installed on the surface of the structure surrounding the gap. For example, if the elastic member 300 is installed on the groove wall of the annular groove 201 (as shown in fig. 4), the annular protrusion 101 or the inner bottom wall of the juice extracting cup 100, the elastic member 300 is installed in the gap and can interfere with the residue entering the gap, so as to prevent the residue from escaping from the filter screen cartridge 200 through the gap and mixing into the juice.

Specifically, the elastic material member 300 may have a ring shape, a block shape, or a bar shape. For example, the resilient material 300 is a resilient ring that fits into the gap. For another example, the number of the elastic material members 300 is plural, and the plural elastic material members 300 are distributed in the gap at intervals, so that the residue entering the gap can be blocked by the elastic material members 300 and cannot pass through the interval between two adjacent elastic material members 300.

In particular, the resilient material 300 may fill the entire gap, such that in the assembled state the sieve cartridge cannot be rotated relative to the juice extractor cup.

The elastic member 300 may not completely fill the gap, and even if the residue enters the gap, the residue may be squeezed back and cannot pass through the gap, thereby facilitating the assembly and disassembly between the strainer cartridge 200 and the juice extractor 100 and saving the consumables of the elastic member 300. In this case, the sieve cartridge 200 can also be rotated relative to the juice extractor cup 100. For example, referring to fig. 7 and 8, the juice extracting structure of the juice extractor further includes a screw 410 and a screw seat 420 disposed at the periphery of the lower portion of the screw 410. Wherein the screw 410 and the screw seat 420 may constitute the screw assembly 400. The outer surface of the screw 410 is provided with a helical cutting edge 412.

Referring to fig. 5 and 8, the screw seat 420 is connected to the top of the strainer cylinder 200, the through hole 430 is communicated with the inside of the strainer cylinder 200, and the rotating shaft 411 of the screw 410 is detachably installed in the installation hole 107, so that the rotating shaft 411 is used for being connected with a driving device of a main machine 500 of the juicer, and the driving device drives the screw 410 and the strainer cylinder 200 to rotate together to extrude fruits and vegetables.

When juicing, the fruits and vegetables sequentially pass through the screw 410, the through hole 430 and the juice squeezing space 102. The fruits and vegetables are initially extruded by the screw 410, and are pushed by the rotating screw 410 and gradually slide down to the through hole 430. Since the through holes 430 are communicated with the strainer cartridge 200, the fruits and vegetables pass through the through holes 430 and then enter the strainer cartridge 200, and are clamped by the extrusion columns 106 and the strainer cartridge 200 for secondary extrusion treatment.

The outer diameter of the squeezing column 106 is gradually reduced along the direction away from the annular protrusion 101, so that the juice squeezing space 102 is in a shape of being large at the top and small at the bottom, the squeezing force applied to the fruits and vegetables is larger and larger, and the juice yield of the fruits and vegetables is higher and higher. Traditional juicing structure, screw rod 410 are located filter screen section of thick bamboo 200, can only carry out once processing to the fruit vegetables, lead to the juice rate low, and extrusion pressure can not gently increase, increases the wearing and tearing of structural component, reduces the life of structural component. The utility model provides a juice structure carries out preliminary extrusion and secondary extrusion to the fruit vegetables in proper order, can improve the juice rate effectively. The juice squeezing space 102 is large at the top and small at the bottom, which is beneficial to gradually increasing the squeezing force and reducing the abrasion of the structural parts. Moreover, the filter screen cylinder 200 can be conveniently positioned and installed on the juice extracting cup 100 in a matching mode of the annular protrusion 101 and the annular groove 201, the annular protrusion 101 can guide the rotary filter screen cylinder 200, and the filter screen cylinder 200 is prevented from being separated from the annular protrusion 101 in the rotating process. It is understood that the annular protrusion 101 may be made of a metal material, such as stainless steel, to ensure its rigidity and strength and prolong its service life.

Further, a scraping brush (not shown) is arranged in the juice storage space 103, and the static scraping brush contacts with the rotating filter screen cylinder 200, so that the mesh of the filter screen cylinder 200 can be cleaned, the mesh is prevented from being blocked, and an additional driving piece is not required to be added for driving the scraping brush to rotate.

Further, referring to fig. 5, 6, 9 and 10, the outer wall of the extrusion column 106 is provided with a first extrusion rib 108, and the inner side wall of the screen cylinder 200 is provided with a second extrusion rib 202. The first and

second ribs

108 and 202 are designed to allow the fruits and vegetables to be squeezed more fully in the juice squeezing space 102.

The number of the first extrusion ribs 108 is multiple, and the multiple first extrusion ribs 108 are distributed along the outer wall of the extrusion column 106 at intervals from top to bottom. And/or the number of the second extrusion ribs 202 is multiple, the second extrusion ribs 202 are distributed at intervals along the inner side wall of the filter screen cylinder 200, and the second extrusion ribs 202 are spirally distributed along the inner side wall of the filter screen cylinder 200 from top to bottom. Each second crush rib 202 protrudes from the inner sidewall of the screen cylinder 200.

It can be understood that the first extruding ribs 108 are distributed on the extruding column 106 in a sparse and dense manner, and the interval between two adjacent first extruding ribs 108 distributed on the upper part of the extruding column 106 is larger, so that the extruding force applied to the fruits and vegetables during the secondary extruding treatment is gradually increased rather than suddenly increased, thereby reducing the noise and the abrasion of the structural members.
