Description
Technical Field
[0001] This invention relates to the field of food processor technology, specifically to a food processor suitable for both forward and reverse mixing and its usage method. Background Technology
[0002] A stand mixer is a multi-functional kitchen appliance mainly used for making Chinese and Western pastries. It uses a motor-driven gear transmission system to perform basic functions such as kneading dough, beating eggs, and mixing. It can replace manual labor and improve baking efficiency. The body is mostly made of metal or ABS engineering plastic. Some models use fiberglass to enhance durability. Most household stand mixers use a planetary mixing structure, and their mixing attachments are all eccentrically installed to achieve the rotation and revolution of the mixing attachments to cover the radial area inside the bowl.
[0003] However, the mixing rod height of existing food processors is fixed. During the mixing process, the material tends to climb upwards along the mixing attachments and the mixing axis, which is called "rod climbing". This is especially true for the egg beater, which has a hollow steel wire structure. When whipping egg whites and cream at high speed, the material will be attracted and climb upwards along the steel wire under the action of centrifugal force, making the rod climbing phenomenon more serious. The fixed height of the mixing rod cannot provide any obstruction to the climbing material, causing the material to continue to climb upwards, eventually filling the mixing axis and contaminating the inside of the machine head. This not only wastes material but also affects the uniformity of mixing and increases the difficulty of cleaning. Summary of the Invention
[0004] To address the shortcomings of existing technologies, this invention provides a food processor suitable for both forward and reverse mixing and its usage method, solving the problem that materials tend to climb upwards along the mixing attachments and mixing axis during the mixing process of existing food processors.
[0005] To achieve the above objectives, the present invention is implemented through the following technical solution: a food processor suitable for forward and reverse mixing and its method of use, comprising a mixer base, a fixed bracket provided above the mixer base, a bowl being detachably mounted on the fixed bracket via a locking block, and a bowl height adjustment mechanism for adjusting the height of the fixed bracket on the mixer base; An upper support frame is rotatably mounted above the mixer base, and a top mounting box is fixed to the top of the upper support frame. The top mounting box is provided with an inspection cover and a stirring mechanism is provided at the bottom of the top mounting box. The stirring mechanism includes a mounting frame set at the bottom of the top mounting box. A fixing block is rotatably mounted inside the mounting frame. A rotating plate is fixedly mounted at the bottom of the fixing block. A stirring rod is detachably mounted on the rotating plate through the mounting mechanism. A gear is fixedly mounted at the top of the mounting mechanism. An internal gear ring is installed inside the mounting frame, and the gear meshes with the internal gear ring. The upper support frame has an internal cavity that is connected to the top mounting box. The upper support frame has an internal up-and-down drive mechanism for driving the mounting frame to move up and down. The top mounting box has an internal transmission mechanism for driving the rotating plate to rotate and for the up-and-down drive mechanism to operate. The transmission mechanism includes a drive motor fixed inside the top mounting box.
[0006] By adopting the above technical solution, and by setting up a basin height adjustment mechanism, a stirring mechanism, and an up-and-down drive mechanism, the basin height adjustment mechanism can adjust the height of the basin, making it convenient to use basins of different depths and improving the applicability. The stirring mechanism can drive the stirring rod to rotate while following the rotating plate, and the stirring rod itself can rotate, thereby improving the stirring effect and efficiency. By setting up an up-and-down drive mechanism, the mounting frame can be driven to move up and down. The up-and-down movement of the mounting frame drives the stirring rod to move up and down synchronously, so that the stirring rod, in addition to its eccentric revolution and rotation, adds axial periodic up-and-down movement, periodically interrupting the material's climbing path and pulling the climbed material back to the stirring area, limiting the material's climbing height within the basin. This effectively solves the problems of the egg beater, dough hook, and flat paddle climbing, sticking to the shaft, wrapping dough, and sticking to the wall, avoiding material waste and machine head contamination, eliminating the need to stop the machine for cleaning, and greatly improving stirring efficiency and ease of use.
[0007] Preferably, the up-down driving mechanism includes a rotating shaft rotatably mounted inside the upper support frame. A rotating disk is fixed to the end of the rotating shaft. A push rod is mounted on the side of the rotating disk. A guide frame is sleeved on the outer surface of the push rod. Multiple connecting rods are fixed to the bottom of the guide frame. The connecting rods are slidably disposed in a strip-shaped slide on the upper support frame. A scale is provided on the upper support frame at the location of the strip-shaped slide. A support ring is fixedly mounted on the outer surface of the mounting frame. Multiple connecting rods are fixedly connected to the support ring. Several telescopic rods are fixedly mounted on the top of the support ring. The top ends of the telescopic rods are all fixedly mounted on the bottom of the top mounting box.
[0008] Preferably, the rotating disc has a mounting groove on its side, a threaded rod is rotatably mounted inside the mounting groove, a handle is fixedly mounted at the bottom of the threaded rod, a sliding block is fixedly mounted at the end of the push rod, the sliding block is slidably disposed against the inner wall of the mounting groove, and the sliding block is threadedly mounted on the outer surface of the threaded rod, and an opening for operation is opened on the side of the upper support frame opposite to the handle.
[0009] Preferably, the mounting mechanism includes a snap-fit housing, a snap-fit rod fixedly mounted on the top of the stirring rod, and the outer surface of the snap-fit rod is provided with an external thread. The snap-fit housing is provided with an internal thread that mates with the external thread. The snap-fit housing is internally mounted with multiple snap-fit blocks via multiple elastic components. The snap-fit rod is provided with multiple slots for the snap-fit blocks to engage. The bottom of the snap-fit block is provided with an arc-shaped surface and an inclined surface. The top of the snap-fit rod is provided with an arc-shaped surface that mates with the arc-shaped surface. A pusher is slidably mounted on the bottom of the snap-fit housing. A wedge-shaped block that mates with the inclined surface is fixed on the top of the pusher.
[0010] Preferably, a sliding rod is fixedly installed on the top of the fixed block, the sliding rod is slidably disposed inside the rotating sleeve, and a plurality of limiting ridges are fixedly installed on the outer surface of the sliding rod, and a limiting groove for the limiting ridges to slide is opened inside the rotating sleeve.
[0011] Preferably, a rotating sleeve connected to a fixed block is rotatably installed inside the top mounting box, a worm is fixedly installed on the outer surface of the rotating sleeve, a worm meshing with a worm wheel is rotatably installed inside the top mounting box, and pulleys are fixed on the outer surfaces of the worm and the motor output shaft, and the two pulleys are connected by a belt.
[0012] Preferably, pulleys 2 are fixedly mounted on the outer surfaces of both the rotating shaft and the output shaft of the drive motor, and the two pulleys 2 are connected by a belt 2 for transmission.
[0013] Preferably, the basin height adjustment mechanism includes a limiting frame fixedly installed on the mixer base, a sliding frame installed on the side of the fixed bracket, the sliding frame being slidably disposed on the outer surface of the limiting frame, a fixing bolt being slidably installed on the sliding frame, and a plurality of fixing holes for the fixing bolt to be inserted into the limiting frame.
[0014] Preferably, the outer surface of the fixing bolt is fitted with an elastic element two, and the two ends of the elastic element two are respectively fixedly installed on the surface of the fixing bolt and the mixer base. A secondary locking rod is fixedly installed on the sliding frame opposite to the fixing bolt, and the fixing bolt is provided with a locking hole for the secondary locking rod to be inserted.
[0015] A method for using a food processor includes the following steps: Place the basin on the bracket and move it by pulling the fixing bolt to release it from the fixing hole. This releases the fixing of the sliding frame and allows the height of the sliding frame to be adjusted according to the depth of the basin. Loosening the fixing bolt and using the elastic element two allows the fixing bolt to be driven into the fixing hole of the limit frame, thus fixing the sliding frame. Then, insert the secondary locking rod to further fix the fixing bolt. Insert the snap-fit rod into the snap-fit housing, rotate the stirring rod to fix it through the external and internal threads, and at the same time, under the action of arc surface one and arc surface two, push the snap-fit blocks on both sides to move to both sides and snap into the snap-fit slots to fix the stirring rod. Depending on the amount of material being fed, the handle is turned at the opening, causing the screw rod to rotate. The rotation of the screw rod drives the sliding block to move the push rod up and down, thereby adjusting the position of the push rod. If the position of the push rod changes, it is adjusted to the corresponding position according to the scale. Then, the drive motor is turned on. The drive motor drives the worm to rotate through pulley one and belt one. The worm drives the rotating sleeve to rotate through the worm wheel. The rotating sleeve rotates and drives the rotating plate to rotate. The rotating plate drives the stirring rod to rotate. At the same time, the stirring rod drives the gear to mesh with the internal gear ring. While driving the stirring rod to follow the rotating plate to rotate, the stirring rod itself can rotate. Simultaneously, the shaft can be driven to rotate synchronously via pulley two and belt two. During the rotation of the shaft, the rotating disc rotates synchronously, which in turn drives the push rod to move. The push rod's movement pushes the guide frame to move up and down, causing the guide frame to drive the support ring frame to move via the connecting rod. The support ring, through the mounting frame, drives the stirring rod to move up and down synchronously, pulling the material that has climbed back into the mixing area. When the material has just climbed a certain distance along the stirring rod, the stirring rod immediately moves downward, forcibly pulling the material back into the mixing area of the basin. When the material tries to climb upward again, the up and down movement of the stirring rod interferes with it again. This cycle repeats, fundamentally blocking the continuous climbing process of the material.
[0016] This invention provides a stand mixer suitable for both forward and reverse mixing, and its method of use. It offers the following advantages: 1. This invention incorporates a basin height adjustment mechanism, a stirring mechanism, and an up-and-down drive mechanism. The basin height adjustment mechanism allows for adjustment of the basin height, facilitating the use of basins of different depths and expanding its applicability. The stirring mechanism drives the stirring rod to rotate while following the rotating plate, simultaneously rotating itself to improve stirring effect and efficiency. The up-and-down drive mechanism drives the mounting frame to move up and down, which in turn drives the stirring rod to move up and down synchronously. This adds axial periodic up-and-down movement to the stirring rod's eccentric revolution and rotation, periodically interrupting the material's climbing path and pulling the material back into the stirring area. This limits the material's climbing height within the basin, effectively solving the problems of the egg beater, dough hook, and flat paddle climbing, sticking to the shaft, wrapping dough, and sticking to the wall, avoiding material waste and machine head contamination, eliminating the need for machine shutdown for cleaning, and significantly improving stirring efficiency and ease of use.
[0017] 2. This invention comprises a snap-fit outer shell, snap-fit blocks, an elastic element, a snap-fit rod, wedge blocks, and a push frame. Pressing the push frame pushes two wedge blocks upwards, causing them to contact the inclined surface of the snap-fit rod. This drives the two snap-fit blocks away from each other, thus releasing them from the slots and releasing the snap-fit rod from its fixation. The snap-fit rod is then inserted into the snap-fit outer shell, and the stirring rod is fixed by external and internal threads. Simultaneously, under the action of arc-shaped surfaces one and two, the snap-fit blocks on both sides are pushed to move to the sides and engage in the slots, thus fixing the stirring rod. This facilitates the replacement of different stirring rods and improves its applicability. The elastic element is preferably a compression spring and a guide rod. The snap-fit blocks are slidably mounted on the surface of the guide rod. The compression spring reduces the vibration of the snap-fit blocks. Magnetic blocks can be installed on the snap-fit blocks, the push frame, and the snap-fit outer shell to further improve stability.
[0018] 3. This invention achieves a dual-effect barrier against material climbing the rod by combining forward and reverse rotation of the stirring rod with axial up-and-down movement. When rotating forward, the material tends to climb, while the reverse rotation disrupts the stable state of the material climbing continuously in a single direction. The axial up-and-down movement pulls the climbed material back into the mixing area. The two work together to completely block the conditions for climbing the rod, sticking to the shaft, wrapping around the dough, and hanging fibers from the direction and trajectory of movement. At the same time, the forward and reverse rotation combined with the up-and-down movement can achieve longitudinal tumbling and radial disturbance of the material in the mixing bowl, greatly improving the uniformity of mixing, making the dough form faster, the whipping finer, and the mixing without dead corners, significantly improving the overall mixing effect and user experience.
[0019] 4. This invention, by setting a threaded rod and a sliding block, allows the screw rod to rotate when the handle is turned at the opening. The rotation of the screw rod drives the sliding block to move the push rod up and down, thereby adjusting the position of the push rod. The change in the position of the push rod can change the range of motion of the guide frame, which is used to change the range of motion according to the amount of material being fed, avoiding the problems of splashing due to insufficient material and reduced effectiveness due to excessive material.
[0020] 5. This invention, by setting a rotating sleeve, a sliding rod, and a limiting edge, utilizes the rotation of the rotating sleeve to drive the sliding rod to rotate through the limiting edge, which in turn drives the rotating plate and the stirring rod to rotate, thereby realizing the stirring operation. The sliding rod and the limiting edge are used for limiting and guiding to ensure that the mounting frame can follow the rotation of the rotating sleeve while moving up and down, thereby reducing the use of driving equipment and improving the convenience of operation.
[0021] 6. This invention, by setting a fixing bolt, a pull handle, and an elastic element two, allows the fixing bolt to move by pulling the handle, causing the fixing bolt to disengage from the fixing hole, thereby releasing the fixing of the sliding frame and adjusting the height of the sliding frame to suit basins of different depths. The elastic element two, when the fixing bolt is released, can drive the fixing bolt into the fixing hole, thus fixing the sliding frame. Attached Figure Description

[0024] The technical solution of the present invention will now be clearly and completely described with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.
[0025] Please see the appendix Figure 1 - Appendix Figure 3 This invention provides a food processor suitable for forward and reverse mixing and its usage method, including a mixer base 1, a fixed bracket 2 above the mixer base 1, a bowl 3 detachably mounted on the fixed bracket 2 via a locking block 4, and a bowl height adjustment mechanism 12 for adjusting the height of the fixed bracket 2 on the mixer base 1. An upper support frame 5 is rotatably mounted on the top of the mixer base 1, and a top mounting box 6 is fixed on the top of the upper support frame 5. The top mounting box 6 is provided with an inspection cover plate 7 and a stirring mechanism 8 is provided at the bottom of the top mounting box 6. The stirring mechanism 8 includes a mounting frame 801 set at the bottom of the top mounting box 6. A fixing block 802 is rotatably mounted inside the mounting frame 801. A rotating plate 803 is fixedly mounted at the bottom of the fixing block 802. A stirring rod 804 is detachably mounted on the rotating plate 803 through a mounting mechanism 9. A gear 805 is fixedly mounted at the top of the mounting mechanism 9. An internal gear ring 806 is installed inside the mounting frame 801, and the gear 805 and the internal gear ring 806 are meshed. The upper support frame 5 has an internal cavity that is connected to the top mounting box 6. The upper support frame 5 has an internal up-and-down drive mechanism 10 for driving the mounting frame 801 to move up and down. The top mounting box 6 has an internal transmission mechanism 13 for driving the rotating plate 803 to rotate and for the up-and-down drive mechanism 10 to run. The transmission mechanism 13 includes a drive motor 1301 fixed inside the top mounting box 6.
[0026] By setting up a basin height adjustment mechanism 12, a stirring mechanism 8, and an up-and-down drive mechanism 10, the height of the basin 3 can be adjusted using the basin height adjustment mechanism 12, making it convenient to use basins 3 of different depths and improving the applicability. The stirring mechanism 8 can drive the stirring rod 804 to rotate with the rotating plate 803, while the stirring rod 804 can also rotate on its own axis, thereby improving the stirring effect and efficiency. By setting up the up-and-down drive mechanism 10, the mounting frame 801 can be driven to move up and down. The up-and-down movement of the mounting frame 801 drives the stirring rod 804 to move up and down synchronously, so that the stirring rod 804, in addition to eccentric revolution and rotation, adds axial periodic up-and-down movement, periodically interrupting the material's climbing path and pulling the climbed material back to the stirring area, limiting the material's climbing height within the basin 3. This effectively solves the problems of the egg beater, dough hook, and flat paddle climbing, sticking to the shaft, wrapping dough, and hanging on the wall, avoiding material waste and machine head contamination, eliminating the need to stop the machine for cleaning, and greatly improving stirring efficiency and ease of use.
[0027] For details, please refer to the appendix. Figure 6 - Appendix Figure 7 The upper and lower drive mechanism 10 includes a rotating shaft 1001 rotatably installed inside the upper support frame 5. A rotating disk 1002 is fixed to the end of the rotating shaft 1001. A push rod 1004 is installed on the side of the rotating disk 1002. A guide frame 1005 is sleeved on the outer surface of the push rod 1004. Multiple connecting rods 1006 are fixed to the bottom of the guide frame 1005. The connecting rods 1006 are slidably arranged in a strip-shaped slide on the upper support frame 5. A scale 11 is provided on the upper support frame 5 at the strip-shaped slide. A support ring 1007 is fixedly installed on the outer surface of the mounting frame 801. Multiple connecting rods 1006 are fixedly connected to the support ring 1007. Several telescopic rods 1003 are fixedly installed on the top of the support ring 1007. The top ends of the telescopic rods 1003 are all fixedly installed on the bottom of the top mounting box 6.
[0028] By setting up a rotating shaft 1001, a rotating disk 1002, a push rod 1004, a guide frame 1005, a connecting rod 1006, and a scale 11, the rotating shaft 1001 drives the rotating disk 1002 to rotate synchronously during rotation. The rotation of the rotating disk 1002 drives the push rod 1004 to move. The movement of the push rod 1004 pushes the guide frame 1005 to move up and down. The guide frame 1005 drives the support ring 1007 to move through the connecting rod 1006. The support ring 1007 drives the stirring rod 804 to move up and down synchronously through the mounting frame 801. Thus, the synchronous up and down movement of the stirring rod 804 is achieved, enabling the stirring rod 804 to move continuously back and forth up and down.
[0029] For details, please refer to the appendix. Figure 7The rotating disc 1002 has a mounting groove on its side. A threaded rod 1011 is rotatably mounted inside the mounting groove. A handle is fixedly mounted on the bottom of the threaded rod 1011. A sliding block 1012 is fixedly mounted on the end of the push rod 1004. The sliding block 1012 is slidably mounted against the inner wall of the mounting groove and is threaded onto the outer surface of the threaded rod 1011. An opening for operation is opened on the side of the upper support frame 5 opposite to the handle.
[0030] By setting up a threaded rod 1011 and a sliding block 1012, rotating the handle at the opening causes the threaded rod 1011 to rotate. The rotation of the threaded rod 1011 drives the sliding block 1012 to move the push rod 1004 up and down, thereby adjusting the position of the push rod 1004. The change in the position of the push rod 1004 can change the range of motion of the guide frame 1005, which is used to change the range of motion according to the amount of material being fed, avoiding the problem of splashing due to insufficient material and reduced effect due to excessive material. By setting up a telescopic rod 1003, the support ring 1007 can be limited and guided, thereby limiting the operation of the mounting frame 801, which will further improve the stability of the movement of the support ring 1007 and the mounting frame 801, and prevent swaying or tilting during operation.
[0031] For details, please refer to the appendix. Figure 4 and attached Figure 9 The mounting mechanism 9 includes a snap-fit housing 901. A snap-fit rod 904 is fixedly mounted on the top of the stirring rod 804, and the outer surface of the snap-fit rod 904 is provided with external threads. The snap-fit housing 901 is provided with internal threads that cooperate with the external threads. A snap-fit block 902 is installed inside the snap-fit housing 901 through multiple elastic elements 903. The snap-fit rod 904 is provided with multiple slots for the snap-fit block 902 to be snapped into. The bottom of the snap-fit block 902 is provided with an arc-shaped surface and an inclined surface. The top of the snap-fit rod 904 is provided with an arc-shaped surface that cooperates with the arc-shaped surface. A pusher frame 906 is slidably mounted on the bottom of the snap-fit housing 901. A wedge block 905 that cooperates with the inclined surface is fixed on the top of the pusher frame 906.
[0032] By configuring a snap-fit housing 901, snap-fit blocks 902, elastic element 903, snap-fit rod 904, wedge blocks 905, and a pusher frame 906, pressing the pusher frame 906 can push the two wedge blocks 905 upwards. The upward movement of the wedge blocks 905 brings them into contact with the inclined surface of the snap-fit rod 904, causing the two snap-fit blocks 902 to move away from each other and disengage from the slot. This releases the fixation on the snap-fit rod 904, further releasing the fixation on the stirring rod 804. The snap-fit rod 904 can then be inserted into the snap-fit housing 901, and the stirring rod 804 can be rotated through the external thread. The internal thread is fixed, and under the action of the first and second arc surfaces, the locking blocks 902 on both sides will be pushed to move to both sides and then lock into the slot, thus fixing the stirring rod 804. This facilitates the replacement of different stirring rods 804 and improves the applicability. The elastic element 903 is preferably a compression spring and a guide rod. The locking block 902 is slidably set on the surface of the guide rod. The compression spring can reduce the vibration of the locking block 902. At the same time, magnetic blocks can be installed on the locking block 902, the push frame 906, and the locking shell 901 to further improve stability.
[0033] For details, please refer to the appendix. Figure 4 - Appendix Figure 6 A sliding rod 1008 is fixedly installed on the top of the fixed block 802. The sliding rod 1008 is slidably disposed inside the rotating sleeve 1010, and several limiting ridges 1009 are fixedly installed on the outer surface of the sliding rod 1008. A limiting groove for the limiting ridges 1009 to slide is opened inside the rotating sleeve 1010.
[0034] By setting up a rotating sleeve 1010, a sliding rod 1008, and a limiting edge 1009, the rotation of the rotating sleeve 1010 can drive the sliding rod 1008 to rotate through the limiting edge 1009. In turn, the sliding rod 1008 drives the rotating plate 803 and the stirring rod 804 to rotate, thereby realizing the stirring work. The sliding rod 1008 and the limiting edge 1009 are used for limiting and guiding work to ensure that the mounting frame 801 can follow the rotation of the rotating sleeve 1010 while moving up and down, thereby reducing the use of driving equipment and improving the convenience of operation.
[0035] For details, please refer to the appendix. Figure 4 - Appendix Figure 6 Inside the top mounting box 6, a rotating sleeve 1010 connected to a fixed block 802 is rotatably mounted. A worm gear 1302 is fixedly mounted on the outer surface of the rotating sleeve 1010. Inside the top mounting box 6, a worm gear 1302 meshing with a worm wheel 1303 is rotatably mounted. Both the worm gear 1302 and the outer surface of the motor output shaft are fixed with pulleys 1304. The two pulleys 1304 are connected by belt 1305. The outer surfaces of the rotating shaft 1001 and the output shaft of the drive motor 1301 are fixedly mounted with pulleys 1306. The two pulleys 1306 are connected by belt 1307.
[0036] By setting pulley 1304 and belt 1305, drive motor 1301 drives worm gear 1302 to rotate via pulley 1304 and belt 1305. Worm gear 1302 drives rotating sleeve 1010 to rotate via worm wheel 1303. At the same time, it can drive rotating shaft 1001 to rotate synchronously via pulley 1306 and belt 1307, realizing synchronous movement of stirring mechanism 8 and upper and lower drive mechanism 10. The simultaneous driving via pulley 1304 and belt 1305 and pulley 1306 and belt 1307 can effectively avoid the impact on drive motor 1301 when jamming occurs. Drive motor 1301 is a motor with forward and reverse rotation function. The forward and reverse rotation of stirring rod 804 makes the stirring more uniform. At the same time, in conjunction with the upper and lower movement, it can disrupt the force direction of material climbing and further hinder climbing, achieving the technical effect of double blocking material climbing rod.
[0037] For details, please refer to the appendix. Figure 4 and attached Figure 9 The basin height adjustment mechanism 12 includes a limiting frame 1202 fixedly installed on the mixer base 1, a sliding frame 1201 installed on the side of the fixed bracket 2, the sliding frame 1201 being slidably disposed on the outer surface of the limiting frame 1202, a fixing bolt 1203 being slidably installed on the sliding frame 1201, a plurality of fixing holes for the fixing bolt 1203 to be inserted into the limiting frame 1202, an elastic element 2 1204 being sleeved on the outer surface of the fixing bolt 1203, the two ends of the elastic element 2 1204 being fixedly installed on the surface of the fixing bolt 1203 and the mixer base 1 respectively, a secondary locking rod 1205 being fixedly installed on the sliding frame 1201 at a position directly opposite to the fixing bolt 1203, and a locking hole for the secondary locking rod 1205 to be inserted into the fixing bolt 1203.
[0038] By setting up a sliding frame 1201, a limiting frame 1202, a fixing bolt 1203, and an elastic element 1204, the fixing bolt 1203 can be moved by pulling it to disengage from the fixing hole, thus releasing the fixing of the sliding frame 1201. The height of the sliding frame 1201 can be adjusted to suit basins 3 of different depths. When the fixing bolt 1203 is released, the elastic element 1204 can drive it to engage with the fixing hole of the limiting frame 1202, thus fixing the sliding frame 1201.
[0039] For details, please refer to the appendix. Figure 9 A secondary locking rod 1205 is fixedly installed on the sliding frame 1201 at the position opposite to the fixing bolt 1203. The fixing bolt 1203 has a locking hole for the secondary locking rod 1205 to be inserted.
[0040] By setting a secondary locking rod 1205, the fixing bolt 1203 can be further fixed, preventing the fixing bolt 1203 from coming out of the hole due to mechanical vibration during operation, and further improving stability.
[0041] A method for using a food processor includes the following steps: Place the basin 3 on the bracket 2. By pulling the fixing bolt 1203, the fixing bolt 1203 is disengaged from the fixing hole, which releases the fixing work on the sliding frame 1201 and allows the height of the sliding frame 1201 to be adjusted according to the depth of the basin 3. After releasing the fixing bolt 1203, the elastic element 1204 causes the fixing bolt 1203 to be driven into the fixing hole of the limiting frame 1202, thus fixing the sliding frame 1201. Then, insert the secondary locking rod 1205 to further fix the fixing bolt 1203. Insert the snap-fit rod 904 into the snap-fit housing 901, rotate the stirring rod 804 to fix it through the external and internal threads, and at the same time, under the action of the first and second arc surfaces, push the snap-fit blocks 902 on both sides to move to both sides and snap into the slots to fix the stirring rod 804. Depending on the amount of material fed in, the handle is turned at the opening, causing the threaded rod 1011 to rotate. The rotation of the threaded rod 1011 drives the sliding block 1012 to move the push rod 1004 up and down, thereby adjusting the position of the push rod 1004. When the position of the push rod 1004 changes, it is adjusted to the corresponding position according to the scale 11. Then, the drive motor 1301 is turned on. The drive motor drives the worm gear 1302 to rotate through the pulley 1304 and belt 1305. The worm gear 1302 drives the rotating sleeve 1010 to rotate through the worm wheel 1303. The rotating sleeve 1010 rotates and drives the rotating plate 803 to rotate. The rotating plate 803 drives the stirring rod 804 to rotate. At the same time, the stirring rod 804 drives the gear 805 to mesh with the internal gear ring 806. While driving the stirring rod 804 to rotate with the rotating plate 803, the stirring rod 804 can also rotate on its own. Simultaneously, the rotating shaft 1001 can be driven to rotate synchronously via pulley 1306 and belt 1307. During the rotation of the rotating shaft 1001, the rotating disk 1002 rotates synchronously. The rotation of the rotating disk 1002 drives the push rod 1004 to move. The movement of the push rod 1004 pushes the guide frame 1005 to move up and down, causing the guide frame 1005 to drive the support ring 1007 to move via the connecting rod 1006. The support ring 1007 drives the stirring rod 804 to move up and down synchronously via the mounting frame 801. This can pull the material that has climbed back to the stirring area. When the material has just climbed a certain distance along the stirring rod 804, the stirring rod 804 immediately moves down, forcibly pulling the material back to the stirring area of the basin 3. When the material tries to climb up again, the up and down movement of the stirring rod 804 interferes with it again. This cycle continues, fundamentally blocking the continuous climbing process of the material.

10. A method of using a food processor, applied to a food processor suitable for forward and reverse mixing as described in any one of claims 1-9, characterized in that, Includes the following steps: Place the basin (3) on the bracket (2), and move the fixing bolt (1203) to disengage it from the fixing hole. This releases the fixing of the sliding frame (1201) and allows the height of the sliding frame (1201) to be adjusted. Adjust the sliding frame (1201) to the corresponding height according to the depth of the basin (3). Loosen the fixing bolt (1203), and under the action of the elastic element (1204), the fixing bolt (1203) can be driven into the fixing hole of the limit frame (1202) to fix the sliding frame (1201). Then insert the secondary locking rod (1205) to further fix the fixing bolt (1203). Insert the snap-fit rod (904) into the snap-fit housing (901), rotate the stirring rod (804) and fix it through the external thread and internal thread. At the same time, under the action of the first arc surface and the second arc surface, the snap-fit blocks (902) on both sides will be pushed to move to both sides and then snap into the slot, thus fixing the stirring rod (804). Depending on the amount of material fed, the handle is turned at the opening, causing the threaded rod 1011 to rotate. The rotation of the threaded rod (1011) drives the sliding block (1012) to move the push rod (1004) up and down, thereby adjusting the position of the push rod (1004). When the position of the push rod (1004) changes, it is adjusted to the corresponding position according to the scale (11). Then, the drive motor (1301) is turned on. The drive motor drives the worm (1302) to rotate through the pulley (1304) and belt (1305). The worm (1302) drives the rotating sleeve (1010) to rotate through the worm wheel (1303). The rotating sleeve (1010) rotates and drives the rotating plate (803) to rotate. The rotating plate (803) drives the stirring rod (804) to rotate. At the same time, the stirring rod (804) drives the gear (805) to mesh with the internal gear ring (806). While driving the stirring rod (804) to rotate with the rotating plate (803), the stirring rod (804) can rotate on its own. Simultaneously, the rotating shaft (1001) can be driven to rotate synchronously through the second pulley (1306) and the second belt (1307). During the rotation of the rotating shaft (1001), the rotating disk (1002) is driven to rotate synchronously. The rotation of the rotating disk (1002) drives the push rod (1004) to move. The movement of the push rod (1004) pushes the guide frame (1005) to move up and down, so that the guide frame (1005) drives the support ring (1007) to move through the connecting rod (1006). (1007) By using the mounting bracket (801) to drive the stirring rod (804) to move up and down synchronously, the material that has climbed can be pulled back to the stirring area. When the material has just climbed up a certain distance along the stirring rod (804), the stirring rod (804) moves down and forcibly pulls the material that has climbed back to the stirring area of the basin (3). When the material tries to climb up again, the up and down movement of the stirring rod (804) will interfere with it again. This cycle continues, blocking the continuous climbing process of the material from the source.
