Description

Technical Field

[0001] This utility model belongs to the field of kitchen appliance technology, specifically relating to a food processing structure and a food processing machine. Background Technology

[0002] A baby food processor is a kitchen appliance used to prepare food for infants and toddlers. It typically includes a motor head, a grinding blade, and a grinding cup. When grinding food, the grinding blade is first placed inside the grinding cup, then the motor head is placed over the rim of the cup, connecting with the grinding blade. However, during the grinding process, the grinding blade comes into contact with the bottom of the baby food cup. The high-speed rotation of the grinding blade causes friction against the bottom wall of the cup, producing food debris, which can lead to black powder residue and potentially affect the baby's health. Utility Model Content

One of the first driving part and the second driving part is provided with an upper rotating member, and the other is provided with an upper rotating fitting member that cooperates with the upper rotating member. The spiral direction of the upper rotating member is opposite to the rotation direction of the pulverizing blade. When the machine head is placed on the blending cup and is in working condition, the second drive unit can cooperate with the first drive unit in an upward rotating manner to enable the second drive unit to drive the blending blade to move upward, and the blending blade can blend the food in a suspended manner inside the blending cup. When the machine head is not in working condition and is raised relative to the blending cup, the second drive unit can detach from the first drive unit due to gravity.

[0005] As an optional implementation, one of the upper screw-on component and the upper screw-on mating component is an external thread, and the other is an internal thread.

[0006] As an optional implementation, one of the internal threads in the first driving part and the second driving part has an inner cavity, the inner wall of the inner cavity is provided with the internal thread, and the inner diameter of the inner cavity gradually decreases from top to bottom; The outer diameter of the columnar structure formed by the external thread during rotation gradually decreases from top to bottom.

[0007] As an optional implementation, when the machine head is placed on the grinding cup and is in a non-working state: there is a first gap between the external thread and the internal thread; When the machine head is in working condition, the first gap between the internal thread and the external thread decreases, or the internal thread and the external thread come into contact.

[0008] As an optional implementation, the bottom of the blending cup is a continuous support surface, which can support the blending blade when the blending blade is not in operation.

[0009] As an optional implementation, the shredder includes a blade shaft and a plurality of blades disposed on the blade shaft. The blade shaft is connected to the second drive unit, the plurality of blades are supported by the support surface, and a second gap exists between the blade shaft and the support surface.

[0011] As an optional implementation, the support surface has an arch shape that gradually protrudes upward from the outer edge to the central region.

[0012] As an optional implementation, the internal thread or the external thread has a helix along the helical direction, and the helix has an angle α between it and the horizontal plane, wherein 45°≤α≤80°.

[0013] As an optional implementation, the cross-section of the internal thread and / or the external thread in the vertical direction has a width L2, where 1.5mm ≤ L2 ≤ 5mm.

[0014] As an optional implementation, the food processing structure further includes a cup lid, which covers the opening, the blending blade passes through the cup lid, and at least a portion of the second drive unit is located above the cup lid.

[0015] The second embodiment of this utility model discloses a food processing machine, comprising: Host; The food processing structure described above includes an outer cup and a detachable baby food cup located inside the outer cup, and the blending blade and the machine head are detachably connected.

[0016] As an optional implementation, the food processor includes two grinding blades, namely a first grinding blade and a second grinding blade. The first grinding blade is used in conjunction with the baby food cup, and the second grinding blade is used in conjunction with the outer cup.

[0017] As an optional implementation, the bottom wall of the outer cup is provided with a first positioning member, and the lower end of the second pulverizing blade is provided with a second positioning member, the first positioning member and the second positioning member being inserted and engaged.

[0018] As an optional implementation, the food processing structure further includes a connecting mechanism, which includes a first connecting part and a second connecting part.

The first connecting part and the second connecting part can be coupled to realize the transmission between the machine head and the grinding blade.

[0019] Compared with the prior art, the beneficial effects of the food processing structure and food processing machine of this utility model are as follows: This invention relates to a food processing structure with a drive mechanism. The first drive unit of the drive mechanism is located on the machine head, and the second drive unit is located on the grinding blade. When the machine head is started, the second drive unit, in conjunction with the upper rotating part and the upper rotating mating part, engages with the first drive unit in an upward rotating manner. This causes the second drive unit to drive the grinding blade away from the bottom of the grinding cup. When the machine head is powered on, it drives the grinding blade to rotate, and the grinding blade grinds the food in a suspended manner. This avoids friction between the grinding blade and the bottom of the grinding cup, preventing the generation of debris and black powder, thus ensuring food safety, especially for infants. Simultaneously, when the machine head is not in operation and is raised relative to the grinding cup, the internal and external threads can rotate and disengage under the gravity of the grinding blade and the second drive unit, allowing the grinding blade to automatically fall back into the grinding cup. This facilitates the connection and separation between the machine head and the grinding blade, improving the overall practicality of the food processing structure. Attached Figure Description

[0028] The technical solution of this utility model will be further described below with reference to the embodiments and accompanying drawings.

[0029] Example 1 Please see Figures 1 to 10 The first embodiment of this application provides a food processing structure 100, including a grinding cup 10, a grinding blade 20, a machine head 30, and a drive mechanism 40.

[0030] Please refer to Figure 1 The blending cup 10 has an opening 16; the blending blade 20 is used to blend the food in the blending cup 10; the machine head 30 is located at the opening 16, and the machine head 30 is equipped with a drive motor 31, which is used to drive the blending blade 20 to rotate so as to blend the food; the drive mechanism 40 includes a first drive part 41 and a second drive part 42. The first drive part 41 is connected to the machine head 30, and the second drive part 42 is connected to the blending blade 20. One of the first drive part 41 and the second drive part 42 is provided with an upper rotating member, and the other is provided with an upper rotating fitting member that cooperates with the upper rotating member. The spiral direction of the upper rotating member is opposite to the rotation direction of the blending blade 20. When the machine head 30 is placed on the blending cup 10 and is in working condition, the second drive unit 42 can cooperate with the first drive unit 41 in an upward rotating manner, so that the second drive unit 42 drives the blending blade 20 to move upward, and the blending blade 20 can blend the food in a suspended manner in the blending cup 10. When the machine head 30 is in a non-working state and is lifted relative to the blending cup 10, the second drive unit 42 can be separated from the first drive unit 41 due to gravity.

[0031] The aforementioned food processing structure 100 includes a drive mechanism 40, with a first drive part 41 mounted on the machine head 30 and a second drive part 42 mounted on the grinding blade 20. When the machine head 30 is started, the second drive part 42, in cooperation with the upper rotating part and the upper rotating mating part, engages with the first drive part 41 in an upward rotating manner, causing the second drive part 42 to drive the grinding blade 20 away from the bottom 11 of the grinding cup 10. When the machine head 30 is powered on and drives the grinding blade 20 to rotate, the grinding blade 20 can be suspended in a suspended manner. By pulverizing the food, friction between the pulverizing blade 20 and the bottom 11 of the pulverizing cup 10 is avoided, thus preventing the generation of black powder and ensuring food safety, especially for infants and young children. At the same time, when the machine head 30 is not in operation and is raised relative to the pulverizing cup 10, the second drive unit 42 can disengage from the first drive unit 41 by gravity, thereby enabling the pulverizing blade 20 to automatically fall back into the pulverizing cup 10. This facilitates the connection and separation between the machine head 30 and the pulverizing blade 20, improving the practicality of the entire food processing structure 100.

[0032] In one embodiment, when the machine head 30 is energized and the second drive unit 42 rotates upwards, one of the first drive unit 41 and the second drive unit 42 may have an external thread 422, and the other may have an internal thread 412. The rotation direction of the first drive unit 41 is opposite to the helical direction of the external thread 422 and the helical direction of the internal thread 412, respectively. As the drive motor 31 rotates, when the first drive unit 41 rotates, the grinding blade 20 is resisted by the food, pushing the internal thread 412 and the external thread 422 to engage. The grinding blade 20 will move upwards until the internal thread 412 and the external thread 422 can engage to achieve the grinding of the food by the grinding blade 20. Specifically, it may include the following methods: (1) The first drive part 41 is provided with an external thread 422, and the second drive part 42 is provided with an internal thread 412; (2) The first drive part 41 is provided with an internal thread 412, and the second drive part 42 is provided with an external thread 422.

[0033] Both of these methods can achieve helical coupling between the first driving unit 41 and the second driving unit 42.

[0034] In another embodiment, when the machine head 30 is powered on and the second drive unit 42 moves in an upward rotation manner, one of the upward rotating part and the upward rotating mating part is an inclined step surface, and the other is a protrusion. For example, the first drive unit 41 may have an inclined step surface, and the second drive unit 42 may have a protrusion. When the machine head 30 is started, under the resistance of the food, the protrusion can rotate upward along the inclined step surface, thereby separating the pulverizing blade 20 from the cup bottom 11. Under the resistance of the food, the pulverizing blade 20 can be in a suspended state to pulverize the food.

[0035] Specifically, in this embodiment, the grinding blade 30 is preferably rotated by the combination of internal and external threads, so as to ensure that the grinding blade 30 can be in a stable grinding state when grinding food, and reduce shaking.

[0036] Please see Figures 1 to 3 In one embodiment of this utility model, when realizing the transmission connection between the shredder 20 and the head 30, the first drive unit 41 includes a power output shaft 411 and an internal thread 412 provided on the inner wall of the power output shaft 411. The power output shaft 411 is connected to the output end of the drive motor 31. The second drive unit 42 includes a mounting shaft 421 and an external thread 422 provided outside the mounting shaft 421. The internal thread 412 and the external thread 422 have the same helical direction. The rotation direction of the first drive unit 41 is opposite to the helical direction of the external thread 422 and the helical direction of the internal thread 412, respectively. The rotation direction of the first drive unit 41 is the power output direction of the drive motor 31. Thus, as... When the drive motor 31 rotates, the first drive unit 41 rotates, and the grinding blade 20 is resisted by the food, pushing the internal thread 412 and the external thread 422 to engage. The grinding blade 20 moves upward until the internal thread 412 and the external thread 422 can engage to grind the food. The grinding blade 20 is detached from the bottom 11 of the grinding cup 10 and will not rub against the bottom 11 of the grinding cup 10, thus avoiding the generation of black powder. At the same time, due to the engagement of the threads, the grinding blade 20 can move upward. There is no need to set a positioning shaft for positioning the grinding blade 20 inside the grinding cup 10. The bottom 11 of the grinding cup 10 is a complete plane, which facilitates subsequent cleaning. In other embodiments, the first drive unit 41 and the second drive unit 42 can also be set to use magnetic attraction to drive the grinding blade 20 to rise. When the drive motor 31 is de-energized, the magnetic force disappears, and the grinding blade 20 can fall downward under its own gravity.

[0037] Specifically, in this embodiment, the first drive unit 41 is connected to the planetary carrier inside the head 30 during installation and rotates together with the planetary carrier.

[0038] It should be noted that when not in operation, the head 30 is mounted at the opening 16 of the blending cup 10, and there is a section of coupling between the first drive part 41 and the second drive part 42, so that when the drive motor 31 is started, the first drive part 41 and the second drive part 42 are engaged. However, there is a certain gap between the top of the blending blade 20 and the top wall of the power output shaft 411. Under the resistance of the food, the external thread 422 of the second drive part 42 can move upward along the internal thread 412, thereby suspending the blending blade 20.

[0039] Specifically, please refer to Figure 3 The upper end of the mounting shaft 421 and the upper top wall of the power output shaft 411 have a distance 43. When the second drive unit 42 rises to its highest point, the distance 43 may be reduced to 0 or not be 0.

[0040] Please also see Figure 3 In order to facilitate the separation of the crushing blade 20 and the first drive unit 41 after the machine is stopped, the width L1 of the first groove 414 between the internal threads 412 is greater than the width L2 of the external threads 422. That is, in the initial state, the walls of the external threads 422 and the internal threads 412 have a first gap 44. In this way, after the machine head 30 is powered off, since the external threads 422 are no longer restricted by the internal threads 412, they can fall down by their own gravity, which facilitates the disassembly between the machine head 30 and the crushing blade 20.

[0041] To ensure stable engagement with the first drive unit 41 after the second drive unit 42 moves upward to its designated position, one of the first drive unit 41 and the second drive unit 42 has an internal cavity 415, with the internal thread 412 on the cavity wall of the cavity 415. The inner diameter of the inner cavity 415 gradually decreases from top to bottom. Similarly, the outer diameter of the columnar structure formed by the external thread 422 during rotation gradually decreases from top to bottom. For example... Figure 9 As shown, the columnar structure formed by the inner cavity 415 and the external thread 422 during rotation is roughly conical in the direction from top to bottom, thereby ensuring that when the second drive part 42 moves upward to its position, the outer wall surface of the external thread 422 can fit against the cavity wall of the inner cavity 415. The first drive part 41 and the second drive part 42 fit tightly together, avoiding swaying during the process of the shredder 20 shredding food.

[0042] Furthermore, when the columnar structure formed by the inner cavity 415 and the outer thread 422 during rotation is approximately conical in the direction from top to bottom, the outer thread 422 and the inner thread 412 have two matching methods: (1) When the machine head (10) is in working state, the first gap 44 between the inner thread 412 and the outer thread 422 decreases. For example, at this time, the inner cavity 415 of the power output shaft 411 is provided with a first limiting step, and the outer wall of the mounting shaft 421 is provided with a second limiting step. The first limiting step supports the second limiting step, thereby achieving a stable cutting state of the shredder 20; (2) The lower wall surface of the corresponding inner thread 412 and the upper wall surface of the outer thread 422 are in contact, that is, at this time, the first gap 44 between the lower wall surface of the inner thread 412 and the upper wall surface of the outer thread 422 is reduced to 0. At this time, the second drive unit 42 can also achieve a stable cutting state of driving the shredder 20. Among them, the state when the shredder 20 is in a suspended state is as follows: Figures 5 to 7 As shown.

[0043] The state between the internal thread 412 and the external thread 422 after the second drive unit 42 rises to its highest point is as follows: Figure 5 and Figure 6 As shown.

[0044] Further, please refer to Figure 1 and Figure 3 To facilitate the docking of the first drive unit 41 and the second drive unit 42, the lower end of the power output shaft 411 is provided with a first chamfer 4111, and / or the upper end of the mounting shaft 421 is provided with a second chamfer 423. In this way, by setting the chamfer, the outer diameter of the upper end of the mounting shaft 421 gradually increases from top to bottom, which has a guiding effect when docking with the first drive unit 41, so as to realize the quick insertion of the two; and / or the inner diameter of the lower end of the power output shaft 411 gradually increases from top to bottom, so as to guide the mounting shaft 421.

[0045] In this embodiment, both the internal thread 412 and the external thread 422 are tapered threads, meaning that the width of the cross-section of the internal thread 412 and the external thread 422 in the vertical direction gradually decreases towards the central axis of the machine head 30.

[0046] Please see Figure 2 , Figure 4 , Figure 7 as well as Figure 10In one embodiment of this utility model, when the machine head 30 is not in operation, the grinding blade 20 and the grinding cup 10 are independently arranged. The lower end of the grinding blade 20 is supported by the bottom 11 of the grinding cup 10. That is, in this embodiment, no positioning shaft is provided in the grinding cup 10 to position the grinding blade 20. Thus, the bottom 11 of the grinding cup 10 forms a continuous support surface 111. When the grinding blade 20 is not in operation, the support surface 111 can support the grinding blade 20. After the food is ground, the grinding blade 20 can be removed from the grinding cup 10 for easy cleaning, avoiding obstruction by the positioning shaft and improving the convenience of cleaning the grinding cup 10. At the same time, since the grinding cup 10 only needs to be cup-shaped, the setting of the positioning shaft is reduced, which facilitates the forming of the grinding cup 10 and reduces the forming difficulty and cost of the grinding cup 10.

[0047] That is, in the initial state, the pulverizing blade 20 is placed inside the pulverizing cup 10 and is in contact with the bottom 11 of the pulverizing cup 10 due to gravity, and is supported by the pulverizing cup 10. When the drive motor 31 is started, the drive motor 31 and the pulverizing blade 20 are connected by transmission, and the pulverizing blade 20 is driven by the second drive unit 42 to move upward and leave the bottom 11 of the pulverizing cup 10.

[0048] The pulverizing blade 20 includes a blade shaft 21 and blades 22 mounted on the blade shaft 21. The pulverizing cup 10 supports the pulverizing blade 20 in the following ways: (1) Multiple blades 22 are supported by a support surface 111, and there is a second gap between the blade shaft 21 and the support surface 111; for example, at this time the blades 22 protrude from the lower end face of the blade shaft 21 toward the lower surface of the support surface 111, thereby achieving contact with the support surface 111; (2) The cutter shaft 21 is supported by the support surface 111, and the blade 22 and the support surface 111 have a third gap 28. For example, at this time, the lower end face of the cutter shaft 21 protrudes from the lower surface of the blade 22 facing the support surface 111, thereby achieving contact between the cutter shaft 21 and the support surface 111. Figure 2 and Figure 5 As shown; (3) Both the cutter shaft 21 and the blade 22 are supported by the support surface 111. For example, at this time, the lower end face of the cutter shaft 21 and the lower surface of the blade 22 facing the support surface 111 are in contact with the support surface 111.

[0049] Furthermore, in order to achieve a preliminary positioning effect for the grinding blade 20, the bottom 11 of the grinding cup 10 in this embodiment arches upwards, and the supporting surface 111 gradually protrudes upwards from the outer edge to the center area in an arched shape, for example... Figure 2 , Figure 4 , Figure 5 , Figure 7 and Figure 10As shown, when the pulverizing blade 20 is placed on the bottom 11 of the pulverizing cup 10, after it is placed stably, it can be roughly judged by the naked eye whether the pulverizing blade 20 is in the center position, so that the raised support surface 111 achieves the positioning effect of the pulverizing blade 20.

[0050] Specifically, in this embodiment, please refer to Figure 5 In the initial state, there is a third gap 28 between the blade 22 and the bottom 11 of the mixing cup 10, and the blade shaft 21 is in contact with the bottom 11. Figure 7 The grinding blade 20 is in the state of being detached from the bottom 11 of the cup. When the grinding is completed and the grinding blade 20 falls back onto the bottom 11 of the grinding cup 10, only the blade shaft 21 and the bottom 11 of the grinding cup 10 are in contact, so as to avoid the blade 22 and the bottom 11 of the grinding cup 10 from colliding and causing mutual damage.

[0051] Please see Figure 3 In this embodiment, the width L2 of the cross section of the internal thread 412 and / or the external thread 422 along the vertical direction is in the range of 1.5mm≤L2≤5mm. By setting the dimensions of the internal thread 412 and / or the external thread 422, the structural strength of the internal thread 412 and / or the external thread 422 is guaranteed, so as to ensure the force requirements during screwing.

[0052] In some embodiments, the value of L2 can be 1.5mm, 2.0mm, 2.5mm, 3mm, 3.5mm, 4.0mm, 4.5mm or 5.0mm, etc., and is not limited here.

[0053] Please see Figure 8 and Figure 9 The internal thread 412 or external thread 422 has a helix m along the helical direction. The helix m and the horizontal plane n have an angle α, which is the helix angle. Here, 45°≤α≤80°. The angle between the helix m and the horizontal plane n represents the lifting force on the pulverizing blade 20 when the second drive unit 42 and the first drive unit 41 are engaged, i.e., the ease of lifting the pulverizing blade 20. A smaller helix angle indicates easier lifting of the pulverizing blade 20. However, the helix angle also affects the lifting force of the first drive unit 41 and the second drive unit 42 when the machine head 30 is placed on the pulverizing cup 10. The ease of docking between the moving parts 42 depends on the initial stage of placing the machine head 30 on the grinding cup 10. The thread of the second driving part 42 needs to be tightly attached to the helix of the first driving part 41 to provide support for the first driving part 41. The smaller the helix angle, the closer the thread is to a horizontal state, and the greater the upward component of the reaction force of the thread on the first driving part 41. The more difficult it is for the machine head 30 to sink and be placed on the grinding cup 10. Therefore, the helix angle is set in the range of 45°≤a≤80°, which not only ensures the lifting force but also facilitates the placement of the machine head 30 on the grinding cup 10.

[0054] In some embodiments, the angle α between the helix m and the horizontal plane n can be 45°, 50°, 55°, 60°, 70°, 75° or 80°, etc., and is not limited here.

[0055] Please see Figure 1 , Figure 2 as well as Figure 5 In one embodiment of this utility model, to prevent the slurry from overflowing from the blending cup 10 during the blending process, the food processing structure 100 also includes a cup lid 50. The cup lid 50 covers the opening 16, the blending blade 20 passes through the cup lid 50, and at least part of the second drive part 42 is located above the cup lid 50. Thus, by setting the cup lid 50, a sealing ring can be set on the outer wall of the cup lid 50, or the cup lid 50 can be directly made of a deformable material to cover the opening of the blending cup 10, preventing the slurry from overflowing from the blending cup 10 or adhering to the machine head 30. That is, the cup lid 50 blocks the main body of the machine head 30 and the blending cup 10. When the slurry is blended, it adheres to the bottom wall of the cup lid 50. Only the cup lid 50 needs to be cleaned, which is convenient for cleaning.

[0056] The blending cup 10 can be integrated with the machine head 30, for example, through a detachable connection or a fixed connection, both of which can achieve the effect of the cup lid 50 blocking the machine head 30 and the blending cup 10. Understandably, the height of the second drive unit 42 and the entire blending blade 20 is higher than that of the blending cup 10, and the second drive unit 42 protrudes from the blending cup 10 so that it can be coupled and docked with the machine head 30.

[0057] Specifically, the shredder 20 in this embodiment includes a blade shaft 21, a blade 22 disposed on the blade shaft 21, and a second drive part 42 connected to one end of the blade shaft 21. The second drive part 42 can be integrally formed with the blade shaft 21, or the two can be separately formed and then reassembled into one unit.

[0058] The outer diameter of the second drive unit 42 is larger than that of the cutter shaft 21. The second drive unit 42 passes through the cup cover 50 and is exposed above the cup cover 50. Therefore, the cup cover 50 is provided with a large through hole 51 for the second drive unit 42 to pass through. In order to prevent the slurry from splashing onto the main unit 60 from the through hole 51, the pulverizing blade 20 also includes a blocking plate 23. The blocking plate 23 is located between the external thread 422 and the blade 22. It can be connected to the cutter shaft 21 or the second drive unit 42. When the second drive unit 42 passes through the cup cover 50, the blocking plate 23 blocks the through hole 51 to prevent the slurry from splashing onto the machine head 30. At the same time, the blocking plate 23 also has the function of limiting the upward movement distance of the second drive unit 42.

[0059] The food processing structure 100 described above has a first drive unit 41 inside the machine head 30 and a second drive unit 42 on the grinding blade 20. The first drive unit 41 can be coupled with the second drive unit 42. Thus, as the drive motor 31 rotates, the grinding blade 20 can move upward under the resistance of the food and disengage from the bottom 11 of the grinding cup 10, avoiding friction with the bottom 11 during the food grinding process and the generation of debris. At the same time, by setting the cross-sectional width of the internal thread 412 and the cross-sectional width of the external thread 422 to be gradually changed, the internal thread 412 and the external thread 422 can be in a beveled fit. When the second drive unit 42 rises to the highest position, the first drive unit 41 and the second drive unit 42 are in a stable coupled state, preventing the grinding blade 20 from shaking during the grinding process.

[0060] Example 2 Please see Figures 11 to 18 The third embodiment of this utility model also provides a food processing machine 200, including a main unit 60 and the above-mentioned food processing structure 100.

[0061] The main unit 60 may be equipped with a heating coil and a control motherboard, etc. The heating coil is used to heat the food in the blending cup 10, and the control motherboard is used to receive control signals to control the start and stop of the drive motor 31. In the above-mentioned food processing structure 100, the blending cup 10 includes an outer cup 12 and a detachable supplementary food cup 13 disposed in the outer cup 12. The blending blade 20 and the machine head 30 are detachably connected.

[0062] Thus, by disassembling the blending blade 20, the baby food cup 13 can be installed as needed to prepare baby food, or water can be poured into the outer cup 12 and heated to cook the food while preparing it, or the baby food cup 13 and blending blade 20 can be used to grind ingredients into powder; or the baby food cup 13 can be disassembled and food can be placed in the outer cup 12. Depending on the speed of the different drive motors 31, liquid food can be prepared through the outer cup 12, achieving the effect of multiple uses in one machine.

[0063] Further, please refer to Figure 12 and Figure 3The food processor 200 of this embodiment may include two grinding blades 20, namely a first grinding blade 24 and a second grinding blade 25. The first grinding blade 24 is adapted to use with a baby food cup 13. In the initial state, it is supported by the baby food cup 13 and used to prepare baby food. The second grinding blade 25 is adapted to use with an outer cup 12. When the outer cup 12 is needed, the baby food cup 13 is disassembled, the second grinding blade 25 is placed inside the outer cup 12, and after the machine head 30 is installed, the food inside the outer cup 12 can be ground by the second grinding blade 25 to prepare liquid food. The first grinding blade 24 and the second grinding blade 25 can be configured with different blade structures 22 according to different grinding scenarios, or the speed of the drive motor 31 can be turned on differently according to different production scenarios to achieve the preparation of different ingredients.

[0064] Understandably, please refer to Figure 14 and Figure 15 Since the baby food cup 13 is installed inside the outer cup 12, the height of the baby food cup 13 is less than the height of the outer cup 12. At this time, the height of the second grinding blade 25 corresponding to the outer cup 12 is higher, so the second grinding blade 25 has a greater degree of freedom. In order to prevent the second grinding blade 25 from shaking, a first positioning member 15 is provided on the bottom wall of the outer cup 12, and a second positioning member 26 is provided at the lower end of the second grinding blade 25. The first positioning member 15 and the second positioning member 26 are inserted and matched. For example, the first positioning member 15 is provided with a positioning hole, and the second positioning member 26 is inserted into the positioning hole, or the first positioning member 15 is a positioning post, and the second positioning member 26 is provided with a positioning hole, and the positioning post is inserted into the positioning hole to achieve the positioning effect of the second grinding blade 25 and prevent shaking. At the same time, there is a gap between the two, which can also realize relative rotation to ensure the normal grinding use of the second grinding blade 25.

[0065] Specifically, in this embodiment, the first positioning member 15 is configured as a positioning post, and the second positioning member 26 is provided with a positioning hole 261.

[0066] Please see Figures 16 to 18 In one embodiment of this utility model, in order to ensure the stability of the drive motor 31 driving the grinding blade 20, the food processing machine 200 further includes a connecting mechanism 70. The connecting mechanism 70 includes a first connecting part 71 and a second connecting part 72. The first driving part 41 is connected to the output end of the machine head 30, and the second connecting part 72 is connected to the grinding blade 20. The first connecting part 71 and the second connecting part 72 can be coupled to realize the rotation of the grinding blade 20 driven by the machine head 30, that is, the grinding blade 20 makes a linear motion along the axial direction parallel to the output shaft of the drive motor 31. During the upward movement, the first connecting part 71 is inserted into the second connecting part 72 or the second connecting part 72 is inserted into the first connecting part 71. When the drive motor 31 rotates, the two have an action force on the plane perpendicular to the vertical direction to realize the drive by the drive motor 31.

[0067] Specifically, in this embodiment, the first connecting part 71 is connected to the output end of the drive motor 31 and is provided with a second cavity 711. The inner wall of the second cavity 711 is provided with a plurality of first teeth 712 extending in the vertical direction, and the outer wall of the second connecting part 72 is provided with a plurality of second teeth 721. When the first connecting part 71 and the second connecting part 72 are coupled, the first teeth 712 enter between the second teeth 721, thereby driving the rotation of the shredder 20 by the drive motor 31.

[0068] The food processor 200 of this embodiment is equipped with two grinding blades 20, which can be adapted to different grinding scenarios. For example, the first grinding blade 24 and the baby food cup 13 can be used to make baby food or grind dry ingredients into powder, while the second grinding blade 25 and the outer cup 12 can be used to make liquid food. This different usage mode increases the practicality of the entire food processor 200.

[0069] The technical means disclosed in this utility model are not limited to those disclosed in the above embodiments, but also include technical solutions composed of any combination of the above technical features. It should be noted that those skilled in the art can make various improvements and modifications without departing from the principle of this utility model, and these improvements and modifications are also considered within the scope of protection of this utility model.
