Description

TECHNICAL FIELD

[0001] The present application relates to the field of food processors, in particular to a multifunctional food processor. BACKGROUND

[0002] The existing multifunctional food processor has the functions of soybean milk, rice paste, dry grinding, shredding and slicing, and dough making, but lacks the function of making pure fruit juice. Because the current food processor generally uses a crushing knife to crush food materials at high speed, if used to make fruit and vegetable juice, there is a problem of not separating the juice residue and needing to dilute water, which affects the taste. Moreover, the fruit juice is easily oxidized and the nutrients are lost because the crushing knife stirs the fruit juice at high speed, increasing the contact probability of the juice and air.

[0003] There is a juice extractor in the prior art that is specially used to make fruit and vegetable juice. Generally, the food material is clamped by the cooperation of the screw rod and the juicing net assembly, the juice flowing down from the juicing net assembly flows out through the juice outlet, and the residue is left in the juicing net assembly and is discharged through the residue discharge port or is poured out, realizing the separation of juice and residue. If the screw rod and the juicing net assembly are applied to the existing food processor to realize the function of pressing fruit and vegetable juice, because the processing cavity of the current food processor is generally a sealed structure or only has a liquid outlet at the bottom, it cannot discharge juice or residue, or simultaneously complete the discharge of juice and residue. The containing space of the juicing net assembly itself is small, and the continuous generation of fruit and vegetable residue will fill the entire containing space and block the juice outlet, part of the juice is left in the juicing net assembly, affecting the juice yield. Moreover, after use, the juicing net assembly is difficult to clean, affecting the user's experience. SUMMARY

[0004] In order to solve one or more technical problems in the prior art, or at least provide a beneficial alternative, the present application provides a multifunctional food processor integrated with a juicing function, realizing rapid separation of juice and residue, which is beneficial to maintaining the fresh taste of fruit and vegetable juice and improving the user's experience.

[0005] The present application provides a multifunctional food processor, which includes a main machine with a built-in motor and a processing cup assembly, the processing cup assembly includes a first cup body and a second cup body, the first cup body can be built into the second cup body, the first cup body is provided with a pressing assembly, the pressing assembly includes a screw rod which can be drivingly connected with the motor and an extrusion cylinder which cooperates with the screw rod to extrude and press juice, a juice collecting cavity is formed between the first cup body and the extrusion cylinder, a convex portion is formed on the bottom of the first cup body upwardly, and at least part of a residue collecting cavity is formed between the convex portion and the second cup body.

[0006] The application provides a food processor with a function of making original juice, which integrates a squeezing assembly in a cup body of the food processor to separate fruit and vegetable juice and residue by squeezing. Specifically, in the present application, a juicing cup body, i.e., a first cup body, is added to an existing processing cup, and the squeezing assembly is arranged in the first cup body. The squeezing assembly includes a screw rod and a squeezing cylinder, and juice is squeezed by the squeezing action between the screw rod and the squeezing cylinder when the screw rod rotates. A juice collecting cavity is formed between the first cup body and the squeezing cylinder, and a protruding portion is formed on the bottom of the first cup body upward to form a partial residue collecting cavity with a second cup body. The squeezing, juice collecting and residue collecting processes are spatially separated to quickly separate juice and residue, avoid mixing fruit and vegetable residue in fruit and vegetable juice, and help to maintain the taste of fruit and vegetable juice. Moreover, the juice quickly flows into the juice collecting cavity, and has a small contact probability with air, which can avoid the problem of easy oxidation of the juice. During the process of squeezing fruit and vegetable juice by the screw rod and the squeezing cylinder, the rotation speed of the screw rod is small, and slow squeezing is performed to generate small noise and good user experience. In the present application, different first cup bodies can be replaced in the second cup body to switch different processing functions, such as a dry grinding cup and a dry grinding assembly, a dough mixing assembly, and the like.

[0007] In a preferred implementation manner of the multifunctional food processor, the squeezing assembly is arranged above the protruding portion, and the squeezing assembly and the protruding portion form a juice discharge channel communicating with the juice collecting cavity.

[0008] On the one hand, the protruding portion is formed on the bottom of the first cup body upward, and the squeezing cylinder is arranged above the protruding portion. The squeezing cylinder and the protruding portion form a juice discharge channel higher than the bottom surface of the juice collecting cavity, and the squeezed fruit and vegetable juice can quickly flow into the juice collecting cavity to avoid being repeatedly squeezed in the squeezing cylinder to be oxidized, improve the freshness of the juice, and have better taste. On the other hand, the vertical depth of a general food processor cup body is large, and the height of the squeezing assembly is smaller than the vertical depth of the cup body. When the squeezing assembly is directly arranged at the bottom of the first cup body, the vertical depth of the first cup body needs to be designed to be small, the volume of the first cup body is too small, and it is not conducive to juice collecting, or a feeding channel needs to be arranged, and the structure is complex. The protruding portion axially supports the squeezing cylinder, the vertical depth of the first cup body is designed to be large, and a partial juice collecting cavity is formed between the top end of the protruding portion and the bottom of the first cup body. The space of the first cup body can be fully utilized, and the space of the juice collecting cavity is large.

[0009] In a preferred implementation manner of the multifunctional food processor, the side wall of the squeezing cylinder is provided with filter bars, the filter bars are arranged at intervals, a filter opening is formed between adjacent filter bars, the protruding portion is provided with a protruding column upward, and the protruding column and the filter opening are inserted to form a juice discharge channel.

[0010] In order to ensure that there is no residue when drinking, the prior art generally uses a filter screen to filter the discharged liquid, the filter screen has a small pore size, and the fine residue is easily blocked in the small holes of the filter screen, which is difficult to clean by flushing alone, and the cleaning is troublesome. Compared with the way of using a filter screen to filter and discharge liquid, in the present scheme, the juice discharge channel with a small size is formed by inserting the filter port and the convex column, and when cleaning, the extrusion cylinder is removed to flush the filter residue on the filter hole. Since the size of the filter hole is larger, it is easy to clean. Moreover, the installation mode of the filter grid and the convex column can form a mutual clamping effect between the extrusion cylinder and the convex part, preventing the screw from rotating and driving the extrusion cylinder to rotate, thereby improving the pressing efficiency.

[0011] In a preferred implementation of a multifunctional food processor, the residue collecting cavity is arranged below the pressing assembly, the convex part is provided with a residue discharge port on the inner side of the convex column, and an elastic plug is arranged at the residue discharge port. The convex part is provided with a positioning column and a limiting part below, the plug includes a plug-in part inserted into the residue discharge port and a positioning part connected with the positioning column, and the limiting part is arranged on one side of the plug and abuts against the plug.

[0012] Since the residue collecting cavity is located below the pressing assembly, there is a height difference between the residue discharge port and the residue collecting cavity, and the fruit and vegetable residue can be smoothly discharged under the action of the extrusion force and gravity, without being repeatedly pressed in the extrusion cylinder, thereby reducing the pressing time and improving the pressing efficiency. Moreover, the elastic plug is arranged at the residue discharge port, and the juice residue discharged outward through the residue discharge port applies pressure to the elastic plug, so that the elastic plug is elastically deformed and forms a residue discharge gap with the residue discharge port to discharge the residue. Under the action of the reaction force of the elastic plug, the juice contained in the fruit and vegetable residue is again pressed between the elastic plug and the residue discharge port, and flows back in the opposite direction with smaller pressure, flows into the juice collecting cavity in the juice discharge channel, improves the juice yield, and further improves the pressing efficiency.

[0013] In a preferred implementation of a multifunctional food processor, the juice collecting cavity surrounds at least part of the pressing assembly and the convex part circumferentially.

[0014] During the working process of the pressing assembly, noise is generated due to the extrusion and grinding between the screw and the extrusion cylinder. The noise collides and reflects multiple times on the wall of the juice collecting cavity, resulting in energy loss, which is beneficial to noise reduction.

[0015] In a preferred implementation of a multifunctional food processor, the processing cup assembly further includes an upper cover, the upper cover includes a feeding port for feeding and a first connecting part connected with the first cup body, and the pressing assembly is arranged above the convex part. When the upper cover is buckled to the first cup body, the upper cover and the convex part limit and fix the pressing assembly.

[0016] The upper cover and the first cup body are matched through the first connecting part, the upper cover and the first cup body are fixedly connected, the pressing assembly is stably clamped and fixed, in the use state, the pressing assembly will not move up and down under the torque of the screw rod, and the stability is ensured. In the non-use state, the pressing assembly can be placed in the first cup body, and the upper cover is covered on the first cup body, which is beneficial to storage.

[0017] In a preferred implementation manner of the multifunctional food processor, the upper cover further comprises a second connecting part connected with the second cup body.

[0018] Further, the upper cover can be matched with the second cup body through the second connecting part, which increases the applicability of the upper cover. In the covered state of the upper cover, the processing cavities of the first cup body and the second cup body can be covered at the same time, and the first cup body and the second cup body are connected through the first connecting part and the second connecting part respectively, which is beneficial to ensuring the stability of the installation of the first cup body. Moreover, after the upper cover and the first cup body are fixedly installed, the second cup body is installed and matched, which avoids the direct installation of the second cup body in the uncapped state of the first cup body, and the problem that the host machine works due to misoperation and the pressing assembly hurts people.

[0019] In a preferred implementation manner of the multifunctional food processor, a sunken table is arranged on the top of the upper cover, and the feeding port is located in the vertical projection range of the sunken table. The sunken table arranged at the feeding port can temporarily store the juice overflowing from the feeding port and flowing out of the upper cover to the host machine or the workbench.

[0020] The processing cup assembly further comprises a trigger switch, which can be triggered when the upper cover is covered on the second cup body or the first cup body to allow the host machine to work. Only when the upper cover is covered, the host machine can work, so as to avoid the situation that the host machine works due to misoperation and the pressing assembly hurts people.

[0021] In a preferred implementation manner of the multifunctional food processor, the side wall of the first cup body extends radially outward to form a support part, and the support part abuts against the upper end of the side wall of the second cup body. The first cup body is hung on the upper cover for installation to be axially limited, which has a higher requirement for the structural strength of the upper cover. The second cup body is used to axially support the first cup body, so that the structural strength of the upper cover does not need to be improved, and the stability is better.

[0022] The first circumferential limiting structure is arranged between the first cup body and the upper cover, the rotation of the first cup body is limited by the upper cover, the rotation of the extrusion cylinder is indirectly limited, the screw rod is prevented from rotating to extrude the food material with the extrusion cylinder, the extrusion cylinder is prevented from rotating under the torque of the screw rod, the pressing efficiency is improved, and noise caused by shaking is avoided.

[0023] The second circumferential limiting structure is arranged between the first cup body and the second cup body, the rotation of the first cup body is limited by the second cup body, the rotation of the extrusion cylinder is indirectly limited, the pressing efficiency is improved, and noise is avoided.

[0024] In a preferred implementation of the multifunctional food processor, the food processor further comprises a speed change mechanism arranged below the second cup body, the speed change mechanism is provided with an input shaft capable of being in driving connection with the motor and an output shaft in driving connection with the screw rod at two ends thereof; the speed change mechanism at least comprises a high-speed output portion and a low-speed output portion, and an output shaft capable of being in driving connection with the high-speed output portion and the low-speed output portion; when the first cup body and the pressing assembly are installed on the second cup body, the low-speed output portion is connected with the output shaft, and the output shaft passes through the slag collecting cavity in the axial direction to be capable of being in driving connection with the screw rod.

[0025] By arranging the speed change mechanism, the power input by the main machine is changed to obtain different rotating speeds and torques to adapt to different processing pieces. In the present scheme, when juicing, the rotating speed of the screw rod is relatively small, and the torque is relatively large, the low-speed output portion and the screw rod are in driving connection, and the requirement of the pressing assembly for slowly pressing fruit and vegetable juice is met.

[0053] The specific solutions are as follows:

[0054] The present application provides a multifunctional food processor, such as Figures 1-3 As shown in the drawings, in one embodiment, the food processor comprises a main machine 1 with a built-in motor and a processing cup assembly 2, the processing cup assembly 2 comprising a first cup body 21 and a second cup body 22, the first cup body 21 being capable of being built into the second cup body 22, the first cup body 21 being provided with a pressing assembly 3, the pressing assembly 3 comprising a screw rod 31 capable of being drivingly connected with the motor, and a squeezing cylinder 32 cooperating with the screw rod 31 to squeeze juice, a juice collecting cavity 23 being formed between the first cup body 21 and the squeezing cylinder 32, a convex portion 211 being formed on the bottom of the first cup body 21 and protruding upward, at least a part of a residue collecting cavity 24 being formed between the convex portion 211 and the second cup body 22, and a juice discharge passage and a residue discharge port 213 being respectively provided between the pressing assembly 3 and the juice collecting cavity 23 and the residue collecting cavity 24. The processing cup assembly 2 is further provided with a juice outlet 29 communicating with the juice collecting cavity 23.

[0055] When the outer diameter of the first cup body 21 is smaller than the inner diameter of the second cup body 22, a gap between the outer wall of the first cup body 21 and the inner wall of the second cup body 22 can form a part of the residue collecting cavity 24, or when the bottom of the first cup body 21 is higher than the second cup body 22, a gap between the inner bottom wall of the second cup body 22 and the outer bottom wall of the first cup body 21 can form a part of the residue collecting cavity 24. In order to maximize the volume of the first cup body 21 and ensure that more fruit and vegetable juice can be stored in the juice collecting cavity 23, in this embodiment, the distance L1 between the outer bottom wall of the first cup body 21 and the inner bottom wall of the second cup body 22 is 0mm < L1 ≤ 20mm, and the distance L2 between the outer diameter of the first cup body 21 and the inner diameter of the second cup body 22 is 0mm < L2 ≤ 20mm.

[0056] The present application provides a food processor with a function of making original juice, which integrates a squeezing assembly 3 in a cup body of the food processor to separate fruit and vegetable juice and residue by squeezing. Specifically, in the present application, a juicing cup body, i.e. a first cup body 21, is added to an existing processing cup, and the squeezing assembly 3 is arranged in the first cup body 21. The squeezing assembly 3 includes a screw rod 31 and an extrusion cylinder 32, and juice is squeezed by the extrusion action between the screw rod 31 and the extrusion cylinder 32 when the screw rod 31 rotates. A juice collecting cavity 23 is formed between the first cup body 21 and the extrusion cylinder 32, and a protruding portion 211 is formed on the bottom of the first cup body 21 to form a partial residue collecting cavity 24 with a second cup body 22. The squeezing, juice collecting and residue collecting processes are spatially separated to quickly separate juice and residue and avoid mixing fruit and vegetable residue in fruit and vegetable juice. Moreover, juice quickly flows into the juice collecting cavity 23 and has a small contact probability with air, which can avoid the problem of easy oxidation of juice and is beneficial to maintaining the nutrition and taste of fruit and vegetable juice. During the process of squeezing fruit and vegetable juice by the screw rod 31 and the extrusion cylinder 32, the rotation speed of the screw rod 31 is small, slow squeezing is performed, and the noise is small, which is good for the user experience. In the present application, different first cup bodies 21 can be replaced in the second cup body 22 to switch different processing functions, such as a dry grinding cup and a dry grinding assembly, a dough mixing cup and a dough mixing assembly, etc.

[0057] As shown in Figures 1-3 In one embodiment, the squeezing assembly 3 is arranged above the protruding portion 211, and a juice discharge channel that communicates with the juice collecting cavity 23 is formed between the squeezing assembly 3 and the protruding portion 211.

[0058] On the one hand, the protruding portion 211 is formed on the bottom of the first cup body 21, and the extrusion cylinder 32 is arranged above the protruding portion 211. The juice discharge channel formed by the extrusion cylinder 32 and the protruding portion 211 is higher than the bottom surface of the juice collecting cavity 23, and the squeezed fruit and vegetable juice can quickly flow into the juice collecting cavity 23 to avoid being repeatedly squeezed and oxidized in the extrusion cylinder 32, improve the freshness of the juice, and have a better taste. On the other hand, the vertical depth of a general food processor cup body is large, and the height of the squeezing assembly 3 is smaller than the vertical depth of the cup body. If the squeezing assembly 3 is directly arranged at the bottom of the first cup body 21, the vertical depth of the first cup body 21 needs to be designed to be small, the volume of the first cup body 21 is too small, which is not conducive to juice collection, or a feeding channel needs to be arranged, which is complex. The protruding portion 211 axially supports the extrusion cylinder 32, the vertical depth of the first cup body 21 is designed to be large, and a partial juice collecting cavity 23 is formed between the top end of the protruding portion 211 and the bottom of the first cup body 21, which can fully utilize the space of the first cup body 21, and the space of the juice collecting cavity 23 is also large.

[0059] As shown in Figure 3 , Figure 5As shown, in one embodiment, the side wall of the extrusion cylinder 32 is provided with filter bars 321, the filter bars 321 are arranged at intervals, the filter ports 322 are formed between adjacent filter bars 321, the convex portion 211 is provided with a convex column 212 upward, the convex column 212 is inserted into the filter port 322 to form a juice discharge channel.

[0060] In order to ensure that there is no residue when drinking, the prior art generally uses a filter screen to filter the discharged liquid, the pore size of the filter screen is generally small, and the fine residue is easy to block in the small holes of the filter screen, and it is difficult to clean only by flushing, and the cleaning is troublesome. Compared with the way of using a filter screen to filter and discharge liquid, in the present scheme, the filter port 322 and the convex column 212 are inserted to form a small size juice discharge channel to discharge juice, and when cleaning, the extrusion cylinder 32 is removed, and the filter residue on the filter hole is flushed. Because the size of the filter hole is larger, it is convenient to clean. Moreover, the installation mode of the filter bar 321 and the convex column 212 can form the effect of mutual clamping between the extrusion cylinder 32 and the convex portion 211, avoiding the rotation of the screw rod 31 driving the rotation of the extrusion cylinder 32, thereby improving the pressing efficiency.

[0061] As shown in the drawings, Figures 3-5 In one embodiment, the residue collecting cavity 24 is arranged below the pressing assembly 3, the convex portion 211 is provided with a residue discharge port 213 on the inner side opposite to the convex column 212, and the residue discharge port 213 is provided with an elastic plug 214. As shown in the drawings, the convex portion 211 is provided with a positioning column 215 and a limiting portion 216 below, the elastic plug 214 includes an insertion portion 2141 inserted into the residue discharge port 213 and a positioning portion 2142 connected with the positioning column 215, the insertion portion 2141 and the positioning portion 2142 are connected, and the limiting portion 216 can be a limiting rib arranged on one side of the plug and abutting against the plug.

[0062] Since the residue collecting cavity 24 is located below the pressing assembly 3, there is a height difference between the residue discharge port 213 and the residue collecting cavity 24, and the fruit and vegetable residue can be smoothly discharged under the action of the extrusion force and gravity, without being repeatedly pressed in the extrusion cylinder 32, thereby reducing the pressing time and improving the pressing efficiency. Moreover, the elastic plug 214 is arranged at the residue discharge port 213, the juice residue discharged outward through the residue discharge port 213 applies pressure to the elastic plug 214, so that the elastic plug 214 is elastically deformed and forms a residue discharge gap with the residue discharge port 213 to discharge the residue. Under the action of the elastic plug 214, the juice contained in the fruit and vegetable residue is pressed again between the elastic plug 214 and the residue discharge port 213, and flows in the opposite direction to the pressure, and flows to the juice collecting cavity 23 in the juice discharge channel, thereby improving the juice yield and further improving the pressing efficiency.

[0063] As shown in the drawings, Figure 2 , Figure 4 In one embodiment, the juice collecting cavity 23 circumferentially surrounds at least part of the pressing assembly 3 and the convex portion 211.

[0064] The squeezing assembly 3 generates noise during work due to extrusion between the screw rod 31 and the extrusion cylinder 32. The noise is reflected multiple times on the wall of the juice collecting cavity 23, resulting in energy loss, which is conducive to noise reduction.

[0065] As shown in Figures 1-3 , Figures 7-9 , in one embodiment, the processing cup assembly 2 further comprises an upper cover 25, the upper cover 25 comprises a feeding port for feeding and a first connecting part connected with the first cup body 21, the squeezing assembly 3 is arranged above the protruding part 211, when the upper cover 25 is buckled on the first cup body 21, the upper cover 25 and the protruding part 211 limit and fix the squeezing assembly 3. The bottom surface of the upper cover 25 is provided with a limiting ring 255, and the opening on the extrusion cylinder 32 cooperates with the limiting ring 255 to limit the circumference.

[0066] The upper cover 25 and the first cup body 21 are cooperatively used through the first connecting part, which can be fixedly connected between the upper cover 25 and the first cup body 21 to stably clamp and fix the squeezing assembly 3. In use, the squeezing assembly 3 will not move up and down under the torque of the screw rod 31, ensuring stability. In a non-use state, the squeezing assembly 3 can be placed in the first cup body 21, and the upper cover 25 is buckled on the first cup body 21, which is conducive to storage.

[0067] As shown in Figures 1-3 , Figures 7-9 , in one embodiment, the upper cover 25 further comprises a second connecting part connected with the second cup body 22. The first connecting part and the second connecting part can be a threaded or screw structure. Preferably, in the present embodiment, the first connecting part is a first inner screw 253 provided on the upper cover 25, and correspondingly, the first cup body 21 is provided with a first outer screw 218 relative to the first inner screw 253. The second connecting part can also be a second inner screw 254 provided on the upper cover 25, and correspondingly, the second cup body 22 is provided with a second outer screw 221 relative to the second inner screw 254.

[0068] The upper cover 25 can also be cooperatively used with the second cup body 22 through the second connecting part, increasing the applicability of the upper cover 25. In the buckled state of the upper cover 25, the processing cavities of the first cup body 21 and the second cup body 22 can be covered at the same time, and the first connecting part and the second connecting part are connected with the two cup bodies respectively, which is conducive to ensuring the stability of the installation of the first cup body 21. Moreover, by fixing and installing the upper cover 25 and the first cup body 21 first and then installing and cooperating with the second cup body 22, the problem of direct installation with the second cup body 22 in the case of opening the first cup body 21, which may cause the host 1 to work and the squeezing assembly 3 to injure people due to misoperation, is avoided.

[0069] The food processor can have two installation modes. One: first, assemble the juicing assembly: install the extrusion cylinder 32 and the screw 31 on the first cup 21 from top to bottom, and then close the upper cover 25, and fix it by rotating the upper cover 25 and the first cup 21. Second, assemble the second cup 22: put the assembled juicing assembly into the second cup 22, and fix it by rotating the upper cover 25 and the second cup 22. Two: install the first cup 21, the extrusion cylinder 32, and the screw 31 from top to bottom, and then close the cover, and fix it by rotating the upper cover 25 and the second cup 22.

[0070] As shown in Figure 3 , Figure 7 In one embodiment, the upper cover 25 has a sunken portion 252 at the top, and the feeding port 251 is located within the vertical projection range of the sunken portion 252. The sunken portion 252 at the feeding port 251 can temporarily store the juice overflowing from the feeding port 251 and flowing out of the upper cover 25 to the main machine 1 or the workbench.

[0071] The processing cup assembly 2 also includes a trigger switch 26, which can be triggered when the upper cover 25 is closed on the first cup 21 or the second cup 22 to allow the main machine 1 to work. Only when the upper cover 25 is closed can the main machine 1 be triggered to work, so as to avoid the situation that the main machine 1 works due to misoperation and the juicing assembly 3 hurts people. In this embodiment, the trigger switch 26 includes a trigger piece 261 provided on the upper cover 25 and a micro switch (not shown in the figure) provided on the second cup 22, which is connected to the main machine 1.

[0072] As shown in Figure 4 In one embodiment, the side wall of the first cup 21 extends radially outward to form a support portion 217, which abuts and supports the upper end of the side wall of the second cup 22. The first cup 21 is hung on the upper cover 25 for installation to limit the axial direction, which requires a higher structural strength of the upper cover 25. However, the method of axially supporting the first cup 21 by the side wall of the second cup 22 does not require improving the structural strength of the upper cover 25, and has better stability.

[0073] As shown in Figure 4 , Figure 11As shown, the first circumferential limiting structure 27 is arranged between the second cup body 22 and the upper cover 25, and includes a first stop rib 271 arranged on one side of a second outer screw knob 221 of the second cup body 22 and a second inner screw knob 254 arranged on the upper cover 25. The second outer screw knob 221 abuts against the first stop rib 271 at the terminal end in the rotation direction of the screw rod 31. When the upper cover 25 is buckled to the second cup body 22, the rotation of the upper cover 25 is limited by the second cup body 22, thereby indirectly limiting the rotation of the first cup body 21 by the upper cover 25, and indirectly limiting the rotation of the extrusion cylinder 32, so as to avoid the rotation of the extrusion cylinder 32 under the torque of the screw rod 31 when the screw rod 31 rotates to extrude the food material, thereby avoiding the low pressing efficiency and the noise caused by the shaking.

[0074] The second circumferential limiting structure 28 is arranged between the first cup body 21 and the second cup body 22, and includes a limiting convex rib 281 arranged on the first cup body 21 and a second stop rib 282 arranged on the second cup body 22 and matched with the stop rib. When the first cup body 21 and the second cup body 22 are installed in place, the limiting convex rib 281 abuts against the second stop rib 282 at the terminal end in the rotation direction of the screw rod 31. Of course, it can be understood that the limiting convex rib 281 can also be matched with a groove arranged on the second cup body 22 to limit the rotation. The rotation of the first cup body 21 is limited by the second cup body 22, thereby indirectly limiting the rotation of the extrusion cylinder 32, improving the pressing efficiency and avoiding the noise.

[0075] As shown in the drawings, Figures 1-3 , Figure 12 In one embodiment, the food processor further includes a speed change mechanism 4 arranged below the second cup body 22. The speed change mechanism 4 includes an input shaft 43 capable of being drivingly connected with the motor, and an output shaft 44 drivingly connected with the screw rod 31. The speed change mechanism 4 includes at least a high-speed output portion 41 and a low-speed output portion 42, and the output shaft 44 is drivingly connected with the high-speed output portion 41 and the low-speed output portion 42, respectively. When the first cup body 21 and the pressing assembly 3 are installed on the second cup body 22, the low-speed output portion 42 is connected with the output shaft 44, and the output shaft 44 axially penetrates the residue collecting cavity 24 to be drivingly connected with the screw rod 31.

[0076] By arranging the speed change mechanism 4, the power input by the main machine 1 is changed to obtain different rotation speeds and torques to adapt to different processing components. In the present scheme, when juicing, the rotation speed of the screw rod 31 is relatively small, and the torque is relatively large. The low-speed output portion 42 is drivingly connected with the screw rod 31 to meet the requirement of slow pressing of fruit and vegetable juice by the pressing assembly 3.

[0077] As shown in the drawings, Figures 1-3As shown, in one embodiment, the juice outlet 29 is at least partially provided on the cup cover. In a food processor with an inner cup and an outer cup, the juice outlet 29 is at least partially provided on the cup cover, which is simple and easy to implement. As shown Figures 13-14 As shown, the cup cover is provided with a first gap 291, and the first gap 291 forms the juice outlet 29. The juice outlet 29 can be closed or opened by providing a flip cover at the gap, which can be closed during juicing to form a sealed environment in the cup, and can be opened when pouring juice; or the gap can be provided as an open type to save the user's time when pouring juice. The first gap 291 is provided at the first inner screw 253 of the cup cover, and the first cup 21 is provided with a cup mouth 219 corresponding to the juice outlet 29. At the first screw structure, the radial distance between the first cup 21 and the cup cover is H1, and the vertical distance between the top surface of the side wall of the first cup 21 and the bottom surface of the cup cover is H2, 0 < H1 ≤ 0.5 mm, and 0 < H2 ≤ 0.5 mm. The bottom surface of the juice outlet 29 is lower than the top surface of the side wall of the cup mouth 219. As shown Figure 15 As shown, the juice outlet 29 is provided with a filter 292. The filter 292 can be a detachable filter screen, and the filter hole can be a metal mesh, which can be circular, square, etc.; or the filter 292 is a filter hole provided on the juice outlet 29, i.e. a porous structure is provided at the juice outlet 29.

[0078] As shown Figure 5 , 16 As shown, in one embodiment, the first gap 291 is provided at the first outer screw 218 of the first cup 21, the juice outlet 29 is formed at the first outer screw 218 of the first cup 21, and the bottom of the juice outlet 29 is higher than the top surface of the side wall of the second cup 22. The juice outlet 29 is provided on the first cup 21, and the juice is directly discharged outward along the inner wall of the first cup 21 and forms a seal at the first outer screw 218, so that liquid leakage does not occur. Moreover, the bottom of the juice outlet 29 is higher than the top surface of the side wall of the second cup 22, so that the juice can flow out smoothly without being blocked by the cup wall of the second cup 22.

[0079] Of course, it can be understood that the cup cover is provided with the first gap 291, the processing cup assembly 2 is provided with the second gap, and the first gap 291 and the second gap jointly form the juice outlet 29.
