Description

Pressing components and juicers

Technical Field

The present application relates to the technical field of juicers, and in particular to a pressing component and a juicer.

Background Art

A juicer is a machine that can quickly squeeze fruits and vegetables into fruit and vegetable juice. It can squeeze juice from many different kinds of vegetables and fruits, and users can choose according to their preferences. Traditional juicers do not have the function of cutting ingredients (such as long-fiber ingredients such as celery, ginger or wheat grass), which often leads to slag blockage after using the juicer for a period of time. After the juicer is blocked, it will not work normally, which seriously affects the user's use.

Utility Model Content

Based on this, it is necessary to provide a squeezing component and a juicer that can effectively cut and chop food.

As shown in Figures 1 and 6, the present application provides a pressing assembly, which includes a pressing screw 100 and a pressing shell 200. The pressing screw 100 has a first pressing part 110 and a second pressing part 120 arranged in sequence from top to bottom, and a first cutter 130 is arranged on the first pressing part 110 and/or the second pressing part 120; the pressing shell 200 has a first pressing chamber 210 and a second pressing chamber 220 arranged in sequence from top to bottom, the first pressing part 110 is at least partially arranged in the first pressing chamber 210, and the second pressing part 120 is at least partially arranged in the second pressing chamber 220, and a second cutter 230 is arranged on the inner wall of the first pressing chamber 210 and/or the second pressing chamber 220, and the first cutter 130 and the second cutter 230 at least partially intersect in the vertical direction to form a shearing structure 201.

The squeezing assembly provided in the present application is provided with a first squeezing chamber 210 and a second squeezing chamber 220 which cooperate with the first squeezing part 110 and the second squeezing part 120 respectively. When the squeezing assembly is in operation, the residue formed by squeezing the food material discharged from the first squeezing chamber 210 will enter the second squeezing chamber 220 for re-squeezing. The re-squeezing of the residue can effectively squeeze out the juice contained in the residue. Therefore, the squeezing assembly can effectively perform double squeezing on the food material. The juice yield of the two squeezings is much greater than that of a single squeezing with the same squeezing stroke, because the second squeezing of the two squeezings is the residue formed after the first squeezing, while the squeezing of a long stroke is a mixture of residue and juice. Therefore, the squeezing assembly effectively improves the juice yield and solves the problem of insufficient juicing.

In addition, in the present application, a first cutter 130 is provided on the first pressing part 110 and/or the second pressing part 120, and a second cutter 230 is provided on the inner wall of the first pressing chamber 210 and/or the second pressing chamber 220. The first cutter 130 and the second cutter 230 at least partially intersect in the vertical direction to form a shearing structure 201. The shearing structure 201 can form a shearing effect on the food, which is beneficial for cutting particularly longer food (such as long-fiber food, specifically celery, ginger or wheat grass, etc.), so that the food can be effectively shortened to facilitate the discharge of residues and extend the juicing time. At the same time, the shearing effect of the shearing structure 201 can also cut the food into smaller pieces and improve the juice yield.

In an optional embodiment, a first cutter 130 is provided on the first pressing section 110, and a second cutter 230 is provided on the inner wall of the first pressing chamber 210, and the first cutter 130 and the second cutter 230 at least partially intersect in the vertical direction to form a shearing structure 201; in another optional embodiment, a first cutter 130 is provided on the second pressing section 120, and a second cutter 230 is provided on the inner wall of the second pressing chamber 220, and the first cutter 130 and the second cutter 230 at least partially intersect in the vertical direction to form a shearing structure 201; in another optional embodiment, a first cutter 130 is provided at the connection between the first pressing section 110 and the second pressing section 120, and a second cutter 230 is provided at the connection between the first pressing chamber 210 and the second pressing chamber 220, and the first cutter 130 and the second cutter 230 at least partially intersect in the vertical direction to form a shearing structure 201.

Specifically, there are multiple shear structures 201, which are arranged at relative intervals, so that the food can be further quickly and effectively cut off to facilitate the discharge of residues, extend the juicing time, and improve the juice yield.

Referring to FIG6 , optionally, the shearing width A of the shearing structure 201 satisfies 0.2 mm ≤ A ≤ 10 mm. Specifically, the shearing width A of the shearing structure 201 refers to the distance between the first cutter 130 and the second cutter 230 in the horizontal direction (i.e., in a direction perpendicular to the vertical direction). A can be 0.5 mm, 2.5 mm, or 6 mm, and A is preferably 2.5 mm.

Referring to Fig. 6, optionally, the shearing height B of the shearing structure 201 satisfies 0.1mm≦B≦5mm. Specifically, the shearing height B of the shearing structure 201 refers to the vertical distance between the first cutter 130 and the second cutter 230. B can be 0.3mm, 1mm or 3mm, and B is preferably 0.3mm.

2 , optionally, the height C of the first cutter 130 satisfies 0.3 mm≦C≦20 mm. Specifically, the height C of the first cutter 130 refers to the length of the first cutter 130 in the radial direction of the pressing screw 100. C can be 2.5 mm, 5 mm or 8 mm, and C is preferably 2.5 mm.

5 , optionally, the height D of the second cutter 230 satisfies 0.3 mm≦D≦20 mm. Specifically, the height D of the second cutter 230 refers to the length of the second cutter 230 in the radial direction of the pressing shell 200. D can be 2.5 mm, 5 mm or 8 mm, and D is preferably 2.5 mm.

4, optionally, the distance E between the first cutter 130 and the bottom end surface of the squeezing screw 100 is ≧15 mm, so as to ensure that there is enough squeezing space to squeeze out the juice after the food is chopped. Specifically, E can be 15 mm, 30 mm or 45 mm, and E is preferably 30 mm.

In order to enable the shearing structure 201 to effectively cut the food, the first cutter 130 is provided with a cutting edge. Further, in order to enable the shearing structure 201 to more effectively cut the food, the second cutter 230 is provided with a cutting edge. Preferably, the cutting edge is a metal cutting edge or a ceramic cutting edge, and the metal cutting edge or the ceramic cutting edge has good wear resistance and can provide better shearing force.

As shown in FIG1 , a first step 140 with an upward surface is provided at the connection between the first pressing part 110 and the second pressing part 120, and a second step 240 with a downward surface is provided at the connection between the first pressing chamber 210 and the second pressing chamber 220, and the first step 140 abuts against the second step 240. The abutment between the first step 140 and the second step 240 can prevent the pressing screw 100 from moving upward when the pressing screw 100 rotates, thereby ensuring the shearing height and shearing effect of the shearing structure 201, stabilizing the pressing screw 100, preventing the pressing screw 100 from shaking, and ensuring the juice extraction efficiency.

As shown in FIG2 , further, a pressing rib 150 is provided on both the first pressing part 110 and the second pressing part 120. The pressing rib 150 on the first pressing part 110 extends from one end of the first pressing part 110 connected to the second pressing part 120 to one end of the first pressing part 110 away from the second pressing part 120; the pressing rib 150 on the second pressing part 120 extends from one end of the second pressing part 120 connected to the first pressing part 110 to one end of the second pressing part 120 away from the first pressing part 110. The pressing rib 150 may be a spiral pressing rib, and the pressing rib 150 on the first pressing part 110 spirally extends along the outer circumference of the first pressing part 110 and around the axial direction of the pressing screw 100, and the pressing rib 150 on the second pressing part 120 spirally extends along the outer circumference of the second pressing part 120 and around the axial direction of the pressing screw 100.

Specifically, one end of the pressing rib 150 on the first pressing part 110 and one end of the pressing rib 150 on the second pressing part 120 are both connected to the surface of the first step 140 .

As shown in FIG2 , the first cutter 130 is provided at one end of the pressing rib 150 on the second pressing part 120 connected to the first pressing part 110. The cutting edge on the first cutter 130 is arranged toward the rotation direction of the pressing screw 100, and the cutting edge on the first cutter 130 includes a first cutting edge section 131 and a second cutting edge section 132 connected to each other. The first cutting edge section 131 and the second cutting edge section 132 are arranged on two adjacent sides of the first cutter 130, and an obtuse angle is formed between the first cutting edge section 131 and the second cutting edge section 132. The length of the first cutting edge section 131 is less than the length of the second cutting edge section 132. The end of the first cutting edge section 131 away from the second cutting edge section 132 is connected to the table surface of the first step 140, and the second cutting edge section 132 is arranged on the side of the first cutter 130 away from the table surface of the first step 140.

Furthermore, a plurality of pressing ribs 150 are provided on the first pressing part 110 and the second pressing part 120. A guide channel 160 is formed between two adjacent pressing ribs 150 on the first pressing part 110 and between two adjacent pressing ribs 150 on the second pressing part 120. The guide channel 160 spirally extends around the axial direction of the pressing screw 100, so that the juice and residue formed after the food is squeezed can be discharged smoothly from the pressing screw 100 along the guide channel 160.

Preferably, the density of the pressing ribs 150 on the second pressing part 120 is greater than or equal to the density of the pressing ribs 150 on the first pressing part 110. The pressing ribs 150 on the second pressing part 120 need to further press the slag, so the greater the density of the pressing ribs 150 on the second pressing part 120, the more conducive it is to squeeze juice from the slag.

There is no fixed shaft at the top of the squeezing screw 100. The squeezing screw 100 can ensure stable rotation and squeezing efficiency by the abutment between the first step 140 and the second step 240. The absence of a fixed shaft at the top of the squeezing screw 100 can make the installation and use of the squeezing screw 100 simpler, and it can be used well without precise alignment. At the same time, it can also avoid occupying too much space in the squeezing chamber, thereby increasing the size of the squeezing chamber. Therefore, when using it, there is no need to cut the food into smaller pieces, and at the same time avoid the phenomenon of too much food stuck in the squeezing chamber, which increases the convenience of use and improves the juicing efficiency.

The diameter of the second pressing part 120 is greater than or equal to the diameter of the first pressing part 110. The larger the diameter of the second pressing part 120, the larger the area where the pressing ribs 150 can be set, which is more conducive to improving the strength and efficiency of pressing, and is conducive to further deep pressing on the basis of the already pressed slag.

As shown in FIG2 , in one embodiment, a slag cutter 170 is further provided at the bottom of the squeezing screw 100. The slag cutter 170 can cut the slag at the bottom of the squeezing screw 100 to prevent the slag from accumulating at the bottom of the squeezing screw 100 and affecting the juice extraction efficiency. Specifically, the slag cutter 170 is connected to the squeezing rib 150 at the bottom of the squeezing screw 100. There are multiple slag cutters 170, and the multiple slag cutters 170 are arranged at intervals on the outer periphery of the squeezing screw 100.

In one embodiment, a slag discharge rib 180 is further provided at the bottom of the pressing screw 100. Specifically, after the slag material reaches the bottom of the pressing screw 100 along the pressing rib 150, it can be quickly discharged from the bottom of the pressing screw 100 under the guidance of the slag discharge rib 180, thereby effectively improving the slag discharge efficiency. Specifically, the outer wall of the slag cutter 170 is provided with a plurality of slag discharge ribs 180, and the plurality of slag discharge ribs 180 are arranged at intervals on the outer periphery of the pressing screw 100.

In one embodiment, a limiting portion 190 is provided on the squeezing screw 100, and the limiting portion 190 is used to limit the axial movement of the squeezing screw 100. Specifically, the limiting portion 190 can abut against the squeezing shell 200 to limit the axial movement of the squeezing screw 100, thereby ensuring the shearing height and shearing effect of the shearing structure 201, and stabilizing the squeezing screw 100 to prevent the squeezing screw 100 from shaking, thereby ensuring the juice extraction efficiency.

The limiting portion 190 includes a limiting ring 191 arranged at the bottom of the pressing screw 100. The limiting ring 191 is arranged along the circumference of the pressing screw 100. The limiting ring 191 is arranged at one end of the second pressing portion 120 away from the first pressing portion 110. The slag cutting knife 170 and the slag discharge rib 180 are both arranged adjacent to the limiting ring 191. Specifically, the limiting ring 191 can abut against the bottom of the pressing shell 200, and the slag cutting knife 170 and the slag discharge rib 180 are both connected to the limiting ring 191.

As shown in FIG. 4 , in one embodiment, a limiting mechanism 192 is further provided between the first pressing section 110 and the second pressing section 120 , and the limiting mechanism 192 is used to limit the rotation of the first pressing section 110 relative to the second pressing section 120 , thereby ensuring the shearing height and shearing effect of the shearing structure 201 .

Specifically, the limiting mechanism 192 includes a limiting column 193 and a limiting hole 194. One of the first pressing section 110 and the second pressing section 120 is provided with a limiting column 193, and the other of the first pressing section 110 and the second pressing section 120 is provided with a limiting hole 194. The limiting column 193 is inserted into the limiting hole 194. The number of the limiting columns 193 and the limiting holes 194 are both multiple, and the multiple limiting columns 193 correspond one-to-one to the multiple limiting holes 194 respectively.

Specifically in this embodiment, a plurality of limiting posts 193 are provided at one end of the first pressing section 110 facing the second pressing section 120, and the plurality of limiting posts 193 are arranged at intervals along the circumference of the first pressing section 110; a plurality of limiting holes 194 are provided at one end of the second pressing section 120 facing the first pressing section 110, and the plurality of limiting holes 194 are arranged at intervals along the circumference of the second pressing section 120, and the plurality of limiting posts 193 correspond one-to-one to the plurality of limiting holes 194, respectively.

As shown in FIG4 , a transmission shaft 195 is also provided at the bottom of the squeezing screw 100. The transmission shaft 195 is used to connect a driving device (such as a motor). The driving device can drive the squeezing screw 100 to rotate through the transmission shaft 195, so that the squeezing screw 100 and the squeezing housing 200 cooperate to squeeze the food to achieve juice extraction. Furthermore, a cavity 196 is also provided at the bottom of the squeezing screw 100. The transmission shaft 195 is provided in the cavity 196. By providing the transmission shaft 195 in the cavity 196, the space utilization rate of the squeezing screw 100 is effectively improved.

Specifically, the cavity 196 is arranged at one end of the second pressing section 120 away from the first pressing section 110, one end of the transmission shaft 195 is embedded in the first pressing section 110, and the other end of the transmission shaft 195 passes through the second pressing section 120 toward one end of the first pressing section 110 and extends into the cavity 196. One end of the transmission shaft 195 extending into the cavity 196 is used to connect a driving device.

As shown in FIG. 3 , a feed rib 250 is disposed on the inner wall of the first pressing chamber 210 and the inner wall of the second pressing chamber 220 . The feed ribs 250 on the inner wall of the first pressing chamber 210 are used to introduce food into the first pressing chamber 210. At the same time, the feed ribs 250 can provide resistance to the rotation of the food, that is, when the first pressing part 110 drives the food to rotate, the feed ribs 250 can block the food, and the food is crushed by the cooperation between the first pressing part 110 and the feed ribs 250, so as to further improve the juicing efficiency of the food; the feed ribs 250 on the inner wall of the second pressing chamber 220 are used to introduce the residue formed by the squeezing of the food into the second pressing chamber 220. At the same time, the feed ribs 250 can provide resistance to the rotation of the residue, that is, when the second pressing part 120 drives the residue to rotate, the feed ribs 250 can block the residue, and the residue is further crushed by the cooperation between the second pressing part 120 and the feed ribs 250, so as to further improve the juicing efficiency of the food.

Furthermore, a plurality of feed cutting ribs 250 are provided on the inner walls of the first pressing chamber 210 and the second pressing chamber 220. The plurality of feed cutting ribs 250 on the inner wall of the first pressing chamber 210 are arranged at circumferential intervals along the first pressing chamber 210, and the plurality of feed cutting ribs 250 on the inner wall of the second pressing chamber 220 are arranged at circumferential intervals along the second pressing chamber 220.

Further, the lowering rib 250 on the inner wall of the first pressing chamber 210 extends from one end of the first pressing chamber 210 connected to the second pressing chamber 220 to one end of the first pressing chamber 210 away from the second pressing chamber 220; the lowering rib 250 on the inner wall of the second pressing chamber 220 extends from one end of the second pressing chamber 220 connected to the first pressing chamber 210 to one end of the second pressing chamber 220 away from the first pressing chamber 210. Specifically, the lowering rib 250 on the inner wall of the first pressing chamber 210 is connected to the table surface of the second step 240, and the bottom end surface of the lowering rib 250 on the inner wall of the first pressing chamber 210 is flush with the table surface height of the second step 240.

As shown in FIG3 , specifically, a second cutter 230 is provided at one end of the lower material rib 250 on the inner wall of the first pressing chamber 210 connected to the second pressing chamber 220. The cutting edge of the second cutter 230 includes a third cutting edge segment 231 and a fourth cutting edge segment 232 provided on opposite sides of the lower material rib 250 on the inner wall of the first pressing chamber 210, and the third cutting edge segment 231 and the fourth cutting edge segment 232 both extend from one end of the lower material rib 250 on the inner wall of the first pressing chamber 210 connected to the second pressing chamber 220 to one end of the lower material rib 250 away from the second pressing chamber 220.

As shown in FIG. 3 and FIG. 5 , further, a first positioning ring 260 is provided at the connection between the first pressing chamber 210 and the second pressing chamber 220 , and the first positioning ring 260 is used to achieve radial limitation between the pressing screw 100 and the pressing shell 200 .

When the squeezing screw 100 tilts relative to the squeezing shell 200 during the rotational operation, the first positioning ring 260 can abut against the squeezing screw 100, thereby realizing radial limitation between the squeezing screw 100 and the squeezing shell 200, improving the operation stability of the squeezing screw 100, ensuring that the squeezing screw 100 does not tilt, thereby avoiding wear of the squeezing screw 100 and the squeezing shell 200, extending the service life of the squeezing screw 100 and the squeezing shell 200, and also preventing the waste formed after the parts are worn from mixing into the juice and affecting the quality of the juice. In addition, when the squeezing screw 100 runs stably, the squeezing gap between the squeezing screw 100 and the squeezing shell 200 is more stable, which can effectively improve the juice extraction efficiency and juice yield, and enhance the user experience.

Specifically, there is a gap between the inner wall of the first positioning ring 260 and the pressing screw 100 to prevent the pressing screw 100 and the first positioning ring 260 from being worn due to continuous contact between the first positioning ring 260 and the pressing screw 100 during the rotation of the pressing screw 100 .

Specifically, the inner wall of the first positioning ring 260 can abut against the step surface of the first step 140, so as to achieve radial limitation between the pressing screw 100 and the pressing shell 200. The step surface of the first step 140 is connected to the table surface of the first step 140, and the step surface of the first step 140 forms an angle with the table surface of the first step 140, which can be an obtuse angle.

Further, the second step 240 includes a first positioning ring 260, and the step surface of the second step 240 constitutes the inner wall of the first positioning ring 260, wherein the step surface of the second step 240 is connected to the table top of the second step 240, and the step surface of the second step 240 forms an angle with the table top of the second step 240, optionally, the angle can be 90 degrees, that is, the step surface of the second step 240 and the table top of the second step 240 are perpendicular to each other.

The first positioning ring 260 is higher than or flush with the lower material rib 250 on the inner wall of the second pressing chamber 220. With such a configuration, when the pressing screw 100 tilts relative to the pressing shell 200 during the rotational operation, the pressing screw 100 first contacts the component closest to the center of the pressing screw 100 inside the pressing shell 200. When the first positioning ring 260 is higher than or flush with the lower material rib 250 on the inner wall of the second pressing chamber 220, the first positioning ring 260 is closest to the center of the pressing screw 100, so that the first positioning ring 260 can be pre-abutted against the pressing screw 100, thereby realizing radial limitation between the pressing screw 100 and the pressing shell 200, improving the running stability of the pressing screw 100, ensuring that the pressing screw 100 does not tilt, thereby avoiding wear of the pressing screw 100 and the pressing shell 200, and extending the service life of the pressing screw 100 and the pressing shell 200.

3 , optionally, the inner diameter A1 of the first positioning ring 260 is ≧30 mm, and A1 may be 30 mm, 50 mm, or 75 mm.

Optionally, the inner diameter A1 of the first positioning ring 260 is greater than half of the maximum diameter of the bottom of the pressing screw 100 to more effectively limit the center of the pressing screw 100 and ensure that the pressing screw 100 does not tilt.

3 , optionally, a distance A2 between the first positioning ring 260 and the bottom end surface of the press shell 200 is ≧10 mm, and A2 may be 15 mm, 30 mm, or 50 mm.

6 , optionally, the distance A3 between the inner wall of the first positioning ring 260 and the pressing screw 100 is ≦0.5 mm, and A3 may be 0.1 mm, 0.3 mm or 0.5 mm.

Optionally, the height A4 of the first positioning ring 260 is ≧2 mm, and A4 may be 3 mm, 5 mm, or 10 mm. Specifically, the height A4 of the first positioning ring 260 refers to the length of the first positioning ring 260 in its own axial direction.

The first positioning ring 260 is coaxially arranged with the pressing screw 100. Such an arrangement effectively increases the axial positioning height of the pressing screw 100, making the pressing screw 100 more stable during operation.

In an optional embodiment, the first positioning ring 260 is a closed and complete annular structure, ensuring that the first positioning ring 260 can fully contact the pressing screw 100, thereby improving the radial limiting effect between the pressing screw 100 and the pressing shell 200 and ensuring the operating stability of the pressing screw 100.

In an optional embodiment, the first positioning ring 260 is partially missing, and the circumference of the partially missing first positioning ring 260 is ≧ half of the circumference of the closed and complete first positioning ring 260. In this way, the structure of the first positioning ring 260 can be simplified and the manufacturing cost of the first positioning ring 260 can be reduced, while ensuring sufficient contact between the first positioning ring 260 and the pressing screw 100 and ensuring the operating stability of the pressing screw 100 without tilting.

As shown in Fig. 3 and Fig. 5, a second positioning ring 270 is further provided at the bottom of the second squeezing chamber 220, and the second positioning ring 270 is used to realize radial limitation between the squeezing screw 100 and the squeezing shell 200. When the squeezing screw 100 tilts relative to the squeezing shell 200 during the rotation operation, the second positioning ring 270 can abut against the squeezing screw 100, so as to realize radial limitation between the squeezing screw 100 and the squeezing shell 200. Therefore, the first positioning ring 260 and the second positioning ring 270 have a double positioning effect on the squeezing screw 100 in the radial direction, so as to more effectively ensure the running stability of the squeezing screw 100, ensure that the squeezing screw 100 does not tilt, thereby avoiding the wear of the squeezing screw 100 and the squeezing shell 200, and extending the service life of the squeezing screw 100 and the squeezing shell 200.

Specifically, the inner wall of the second positioning ring 270 can abut against an end of the second pressing part 120 away from the first pressing part 110 , so as to achieve radial limitation between the pressing screw 100 and the pressing shell 200 .

Preferably, the second positioning ring 270 is coaxially arranged with the first positioning ring 260. Such an arrangement effectively increases the axial positioning height of the pressing screw 100, making the pressing screw 100 more stable during operation.

The first positioning ring 260 and the pressing screw 100 are made of different materials. Since different materials have different friction coefficients, the friction between the first positioning ring 260 and the pressing screw 100 can be effectively reduced by setting the first positioning ring 260 and the pressing screw 100 to be made of different materials, thereby reducing the wear of the first positioning ring 260 and the pressing screw 100.

The material of the first positioning ring 260 is metal. Specifically, the material of the first positioning ring 260 can be stainless steel or hard aluminum.

Preferably, the second positioning ring 270 is made of a different material from the pressing screw 100, and the second positioning ring 270 is made of metal. Specifically, the second positioning ring 270 may be made of stainless steel or hard aluminum.

As shown in FIG1 , the squeezing housing 200 includes an inner housing 280 and an outer housing 290 sleeved outside the inner housing 280. The inner housing 280 has a first squeezing chamber 210 and a second squeezing chamber 220 arranged sequentially from top to bottom. The outer housing 290 is provided with a juice outlet channel 202 and a slag outlet channel 203, and both the juice outlet channel 202 and the slag outlet channel 203 are connected to the second squeezing chamber 220. The juice outlet channel 202 and the slag outlet channel 203 are arranged on opposite sides of the outer housing 290. The juice outlet channel 202 is used to discharge the juice in the second squeezing chamber 220 to the outside, and the slag outlet channel 203 is used to discharge the slag in the second squeezing chamber 220 to the outside.

In one embodiment, the first pressing chamber 210 is conical and has a flared upper end, with a regular structure and convenient processing, so that the center of gravity of the entire pressing shell 200 remains unchanged, and the first pressing chamber 210 can also be made into other shapes as needed. The second pressing chamber 220 is cylindrical, and the second pressing chamber 220 can also be made into other shapes as needed.

In one embodiment, the inner diameters of the first pressing chamber 210 and the second pressing chamber 220 are inconsistent, and the diameters of the first pressing part 110 and the second pressing part 120 are inconsistent. The pressing chambers with different inner diameters are matched with the pressing parts with different diameters, so that the pressing parts with different diameters can respectively achieve better pressing effects.

As shown in FIG1 , the pressing shell 200 further has a feed cavity 291, which is disposed at one end of the first pressing cavity 210 away from the second pressing cavity 220. Specifically, the inner shell 280 has the feed cavity 291, and the feed cavity 291, the first pressing cavity 210, and the second pressing cavity 220 are sequentially disposed from top to bottom. The feed cavity 291 is cylindrical, and the feed cavity 291 can also be made into other shapes as required.

Furthermore, a juice collecting chamber 292 is provided between the inner shell 280 and the outer shell 290, and the juice collecting chamber 292 is connected with the first squeezing chamber 210, the second squeezing chamber 220 and the juice outlet channel 202. The first squeezing chamber 210 and the second squeezing chamber 220 can collect juice through the juice collecting chamber 292, and then discharge juice through the juice outlet channel 202, so that the residue falling from the first squeezing chamber 210 to the second squeezing chamber 220 can be as free of juice as possible, thereby effectively improving the effect of re-squeezing the residue.

Optionally, the juice collecting chamber 292 includes a first juice collecting chamber 293 and a second juice collecting chamber 294 which are arranged in sequence from top to bottom. The first juice collecting chamber 293 connects the first squeezing chamber 210 and the juice outlet channel 202, and the second juice collecting chamber 294 connects the second squeezing chamber 220 and the juice outlet channel 202. The first squeezing chamber 210 and the second squeezing chamber 220 can collect juice through the first juice collecting chamber 293 and the second juice collecting chamber 294 respectively, and then both discharge juice through the juice outlet channel 202, so that the residue falling from the first squeezing chamber 210 to the second squeezing chamber 220 can be made to carry as little juice as possible, thereby effectively improving the effect of re-squeezing the residue.

Preferably, the first juice collecting chamber 293 is sealed from the second juice collecting chamber 294. The juice in the first juice collecting chamber 293 can only flow out through the juice outlet channel 202, and the juice in the second juice collecting chamber 294 can only flow out through the juice outlet channel 202, and the juice in the first juice collecting chamber 293 will not flow into the second juice collecting chamber 294, so as to prevent the juice from flowing back and causing the residue in the second pressing chamber 220 to be re-infiltrated with juice, thereby affecting the juice outlet efficiency.

As shown in Fig. 3, the pressing shell 200 further includes a filtering structure 295, which is disposed on the side wall of the inner shell 280. The filtering structure 295 is used to filter the juice and residue in the first pressing chamber 210 and the second pressing chamber 220 to separate the juice and residue. By disposing the filtering structure 295 on the side wall of the inner shell 280, there is no need to install an additional filtering device, which is easy to install, reduces the space occupied by the filtering device, and thus reduces the size of the pressing shell 200 and reduces the material cost.

In one embodiment, the filter structure 295 includes a filter screen 296 disposed on the side wall of the inner shell 280 to improve the filtering effect of the filter structure 295. In one embodiment, the filter screen 296 is detachably disposed on the side wall of the inner shell 280, or the filter screen 296 and the inner shell 280 are integrally formed.

The filter 296 is detachably arranged, and this design is convenient for cleaning and replacement of the filter 296. For example, if you want to clean the filter 296 after using it for a period of time, you can directly remove the filter 296 from the inner shell 280 for cleaning, which is convenient to operate; or if the filter 296 is damaged, you can directly replace it with a new one without replacing the entire inner shell 280, which saves costs. When the filter 296 and the inner shell 280 are integrally formed, it is convenient to produce, reduce processing steps, and increase production efficiency.

Furthermore, the pores of the filter screen 296 corresponding to the second squeezing chamber 220 are smaller than or equal to the pores of the filter screen 296 corresponding to the first squeezing chamber 210. The filter screen 296 corresponding to the second squeezing chamber 220 corresponds to the filtration after further squeezing of the slag, so a finer filter screen 296 is conducive to squeezing juice from the slag, and can also prevent fine slag from leaking through the filter screen 296, causing the juice to contain fine slag and affecting the quality of the squeezed juice.

The present application also provides a juicer, which includes the above-mentioned pressing assembly.
