The quality of the service performance of the food processor is related to the performance of a cutter in the food processor, and the performance of the cutter comprises the chopping function of the cutter body on food materials and the convenience of the installation operation of the cutter relative to a pot body. The body of the knife is often particularly sharp because it is necessary to cut up the food material. When the cutter is disassembled and assembled, the table top is prevented from being injured by the sharp cutter, and the table top is important to even hurt a user.

As shown in fig. 1 to 14, the present embodiment provides a food processor 1000, which is mainly used for chopping, stirring and the like of food materials, and even can heat the food materials. Wherein, cooking machine 1000 includes pot body 101, cutter 200 and lock sword structure 300. The knife locking structure 300 is installed at the bottom of the pot body 101 to lock the knife 200 to the pot body 101. The blade locking structure 300 also prevents the blade 200 from being suddenly dropped during the process of disassembling and assembling the blade 200, which will be described later.

As shown in fig. 1-7, a pan base 102 is installed at the bottom of a pan body 101, and the pan base 102 is used for supporting the pan body 101, so that the pan body 101 can be stably placed on a table top or installed on a structure where the pan body 101 needs to be seated. The cooking cup 100 is formed by the pot body 101 and the pot holder 102. The pot body 101 has a cooking cavity for containing food material. The knife locking structure 300 is mounted on the bottom 1011 of the pot body 101 and is accommodated in the pot base 102. The bottom 1011 of the pan body 101 is provided with a knife mounting hole 1012, and one end of the knife 200 passes through the knife mounting hole 1012 to be matched with the knife locking structure 300. The cooking cup 100 further comprises a cup cover 103 buckled on the pot body 101, and the cup cover 103 is used for sealing the cup opening of the pot body 101. Meanwhile, the side wall of the pot body 101 is also provided with a handle so as to be convenient for a user to take.

As shown in fig. 1-3, in some embodiments, the food processor 1000 further comprises a base 400, the food cup 100 can be removably connected to the base 400, and the motor is disposed on the base 400. When the food processing cup 100 is mounted on the base 400, the knife shaft 202 can be matched with the power output end of the motor arranged on the base 400, so that the knife shaft 202 rotates, and the knife body 203 is driven by the knife shaft 202 to operate. The bottom 1011 of the pot body 101 can also be provided with a heating device, and the arrangement can enable the cooking machine 1000 to have a heating function. When the cooking cup 100 is seated on the base 400, the heating device on the pot body 101 can be communicated with the power supply on the base 400, and the heating device can generate heat so as to heat food in the pot body 101. In other embodiments, the food processing cup 100 is fixedly positioned relative to the base 400, thereby improving the structural integrity of the food processor 1000.

The details of the lock blade structure 300 are described below.

As shown in fig. 4-14, the knife locking structure 300 comprises a knife locking block 301, and the knife locking block 301 is used for locking and mounting the knife 200 on the pan body 101. The lock block 301 has a lock cavity 3011, the lock cavity 3011 is used for accommodating the tool holder 201 of the tool 200, and the tool holder 201 is configured with a protrusion 2011 extending radially outwards. The side of the locking knife block 301 facing the pot opening is provided with a support 302, at least part of the support 302 extends radially inwards and beyond the edge of the locking cavity 3011. In the first state, the knife locking block 301 presses the outside of the bottom 1011 of the pot 101, so that the knife 200 is locked and installed on the pot 101, and the supporting part 302 is positioned above the protrusion 2011; in the second state, lock block 301 is disengaged from pan 101, support 302 is held above protrusion 2011, and support 302 can receive protrusion 2011 to support knife 200. The first state represents a state that the cutter 200 is locked with respect to the pot body 101 by the cutter locking block 301, and the second state represents a state that the cutter 200 is in a loose state with respect to the pot body 101, which may be a state of detaching the cutter, or a state that the cutter 200 is not locked with respect to the pot body 101. In fig. 4, the direction C indicates upward, and the direction C' indicates downward.

In case the pan body 101 is turned upside down (i.e. with the pan mouth facing the table top), the knife 200 will tend to fall with respect to the pan body 101 in a direction towards the pan mouth. In this case, the supporting portion 302 of the blade-locking block 301 can support the protrusion 2011 of the blade holder 201, so as to reduce or even inhibit the falling tendency of the blade 200, so that the user can safely contact the blade 200, and the blade 200 can be prevented from hurting the tabletop or injuring the user. For example, when the pot body 101 is turned upside down to detach the cutter 200 relative to the cutter locking structure 300, the cutter locking block 301 is rotated relative to the pot body 101, so that the cutter locking block 301 is gradually loosened relative to the pot body 101, the locking force of the cutter locking block 301 on the cutter 200 is gradually reduced, and the cutter 200 has a tendency to fall in a direction toward the pot opening relative to the pot body 101. At this time, the support portion 302 is located below the protrusion 2011, so that the protrusion 2011 on the tool holder 201 can contact with a portion of the support portion 302, which crosses the edge of the locking cavity 3011, and is supported by the support portion 302, thereby supporting the tool 200 through the support portion 302, effectively reducing a tendency that the tool 200 is directly separated from the tool locking block 301, and reducing potential safety hazards. That is to say, this lock sword structure 300 is through setting up supporting part 302 in the one side of lock sword piece 301 towards pot body 101, when the relative pot body 101 of cutter 200 has the trend that drops along orientation pot mouthful direction, supporting part 302 can support arch 2011 on the tool holder 201, realizes the support to cutter 200, and then improves the problem that cutter 200 directly drops easily when tearing open the sword, reduces cutter body 203 damage or the risk of cutting the user in the cutter 200 to improve cooking machine 1000's safety in utilization and user experience and feel.

As shown in fig. 4-14, in some embodiments, the number of protrusions 2011 is multiple, and the multiple protrusions 2011 are circumferentially spaced. The support 302 includes a plurality of circumferentially spaced support arms 3021, with each projection 2011 corresponding to a support arm 3021. Due to the arrangement, the contact area between the supporting part 302 and the tool holder 201 is increased, the structure which is in contact with the supporting part 302 is ensured along the circumferential circle of the tool holder 201, the stress balance of the supporting part 302 on the tool holder 201 is improved, and the supporting effect on the tool 200 is improved. Typically, one projection 2011 corresponds to one support arm 3021.

As shown in fig. 13, in one embodiment, the support arm 3021 is provided directly on the block 301. In some embodiments, the support arm 3021 is bonded to the block 301 with an adhesive. For example, the support arm 3021 can be glued to the cavity wall of the locking cavity 3011 on the block 301. Of course, the support arm 3021 can be bonded to the side of the knife block 301 facing the pot opening. Specifically, a plurality of supporting arms 3021 arranged at intervals in the circumferential direction are arranged on one side of the knife block 301 facing the pot opening, and each supporting arm 3021 extends radially inwards from the cavity wall of the locking cavity 3011 so as to be capable of bearing a protrusion 2011 on the knife holder 201. Wherein, the protruding arch 2011 that is equipped with a plurality of circumference interval arrangements at the lateral wall of blade holder 201, every arch 2011 all radially outwards extends from the lateral wall of blade holder 201, and every arch 2011 all corresponds there is support arm 3021. As described above, when the tool 200 has a tendency to fall in a direction toward the pot opening with respect to the pot body 101, each protrusion 2011 corresponds to the support arm 3021 for supporting as the tool 200 falls toward the side of the pot opening, thereby improving the support performance of the support 302 for the tool 200.

In another embodiment, as shown in fig. 12, a support ring 3024 is fixedly disposed on the top surface of the lock block 301, such as by adhesive bonding. The back-up ring 3024 extends radially inward beyond the edge of the locking cavity 3011. Here, a portion of the support ring 3024 that crosses the edge of the lock cavity 3011 functions to support a cutter to form the support portion 302. This arrangement ensures that the protrusion 2011 of the holder 201 has the support portion 302 around the lock block 301, thereby improving the support performance for the tool 200. The arrow D in fig. 4 indicates the top surface of the lock block 301.

In yet another embodiment, the cross-section of the support ring 3024 is stepped. That is, in a radially inward extending direction, the thickness of the extended end of the bolster 3024 is greater than the thickness of the end of the bolster 3024 that is connected to the lock block 301. The end connected with the lock cutter block 301 is used as the first end of the support ring 3024, the extending end of the support ring 3024 is used as the second end, a right-angle included angle is formed between the first end and the second end, and the edge of the lock cutter block 301 is just clamped at the included angle, so that the support ring 3024 is conveniently and stably installed together relative to the lock cutter block 301.

As shown in fig. 4, 6, 7, 9 and 14, in another embodiment, the protrusion 2011 of the tool holder 201 is multiple, and the multiple protrusions 2011 are circumferentially spaced. One side of the knife locking block 301 facing the pot opening is provided with a mounting groove 3012. The mounting groove 3012 is provided with a plurality of notches 3013 on the side wall facing the locking cavity 3011. The support portion 302 is configured as a support ring 3022 that fits within the mounting slot 3012, the support ring 3022 having a plurality of circumferentially spaced support arms 3021. The support arms 3021 extend radially inward past the edges of the locking cavity 3011 through respective notches 3013. Each protrusion 2011 corresponds to a support arm 3021. The direction indicated by the arrow a in fig. 4 is the radially inward direction, and the direction BB' in fig. 4 is the depth direction of the mounting groove.

Specifically, one end face of the knife locking block 301, which is used for being tightly pressed against the bottom 1011 of the pot body 101, is provided with a mounting groove 3012, and the mounting groove 3012 is in a ring-shaped groove structure. The support ring 3022 is accommodated in the mounting groove 3012, and the support ring 3022 is not easy to be dislocated and circumferentially rotated relative to the lock cutter block 301 under the limit of the notch 3013 on the support arm 3021. In this way, each protrusion 2011 on the tool holder 201 can be supported by the corresponding supporting arm 3021, so that the supporting effect on the tool 200 is improved. Meanwhile, the support ring 3022 is accommodated in the installation groove 3012, so that the support ring 3022 can be rapidly assembled and replaced, and the installation efficiency is improved. In addition, when the support portion 302 includes the support ring 3022 and the support arm 3021, the support ring 3022 is integrally formed with the support arm 3021, thereby improving the reliability of connection therebetween.

In other embodiments, the height of the inner ring side of the mounting groove 3012 and the height of the outer ring side of the mounting groove 3012 are not particularly limited. The height of the inner ring side of the mounting groove 3012 may be equal to the height of the outer ring side thereof, or the height of the inner ring side of the mounting groove 3012 may be smaller than the height of the outer ring side thereof, or the height of the inner ring side of the mounting groove 3012 may be higher than the height of the outer ring side thereof.

In one embodiment, support arm 3021 has a radial extension between 0.2cm and 0.5 cm. The locking cavity 3011 is typically 2cm to 4cm in diameter. It has been found that support arm 3021 of this length is sufficient to support tool 200, and that the extension of support arm 3021 within locking cavity 3011 is small and does not adversely affect the installation or removal of tool 200. For example, with the above structure, the supporting force of the supporting portion 302 is greater than 20% -40% of the gravity force of the tool 200. With such an arrangement, the support performance of the support 302 for the cutter 200 can be improved, so that the cutter 200 can be supported more safely and the cutter 200 can be prevented from falling off the support 302. In some embodiments, the support arm 3021 may have a radial extension of 0.2cm, 0.3cm, 0.35cm, 0.46cm, 0.5cm, and the locking cavity 3011 may have a diameter of 2cm, 3.6cm, 4cm. The specific numerical values and even the proportion design are selected according to the actual situation.

As shown in fig. 8, in one embodiment, the extension length of the notch 3013 along the circumferential direction of the lock blade block 301 is greater than or equal to the extension length of the support arm 3021 along the circumferential direction of the lock blade block 301. When the extension length of the notch 3013 along the circumferential direction of the lock blade block 301 is equal to the extension length of the support arms 3021 along the circumferential direction of the lock blade block 301, one notch 3013 corresponds to one support arm 3021, and at this time, both sides of the support arms 3021 along the circumferential direction of the lock blade block 301 are just in contact with both side walls of the notch 3013 along the circumferential direction of the installation groove 3012. With such an arrangement, not only the support arm 3021 can conveniently extend out through the notch 3013, but also when the knife 200 is dismounted, the protrusion 2011 is located in the notch 3013 and is inevitably supported by the support arm 3021, which further improves the use safety of the food processor. In further embodiments, the notches 3013 can be used for two or more support arms 3021 to protrude if the extension of the notch 3013 in the circumferential direction of the lock block 301 is greater than the extension of the support arms 3021 in the circumferential direction of the lock block 301. In fact, several support arms 3021 are extended for each notch 3013, and the length of extension between the support arm 3021 and the notch 3013 can be set as needed.

As shown in fig. 8, in one embodiment, the support ring 3022 has a thickness equal to the depth of the mounting slot 3012. That is, when the support ring 3022 is received in the mounting slot 3012, the top surface of the support ring 3022 is flush with the edge of the notch of the mounting slot 3012. In this case, when the blade-locking block 301 is locked with respect to the pot body 101, the edge of the slot of the mounting slot 3012 is in press fit with the bottom 1011.

In other embodiments, the support ring 3022 has a thickness greater than the depth of the mounting slot 3012. When the knife block 301 is screwed tightly against the pan body 101, the support ring 3022 is also compressed between the knife block 301 and the pan bottom 1011, whereby the support ring 3022 also acts like a washer, helping to stably mount the knife block 301 and the knife 200 on the cooking cup.

As shown in fig. 8 and 9, in some embodiments, the support ring 3022 has a first coarse texture 3023 and the support arm 3021 has a second coarse texture. In the case that the thickness of the supporting ring 3022 is greater than the depth of the mounting groove 3012, when the knife lock block 301 locks the knife 200 with respect to the pot body 101, the first rough texture 3023 increases the friction force between the supporting ring 3022 and the pot bottom 1011, which helps the knife lock block 301 lock the knife 200. The friction force of the support arm 3021 in contact with the protrusion 2011 can be increased by the arrangement of the second coarse grains, so that the support performance of the cutter 200 is improved. First coarse texture 3023 and the second coarse texture may be the same or different. In other embodiments, only the first coarse texture 3023 or only the second coarse texture may be provided. Either arrangement may be used, so long as it facilitates assembly and disassembly of the support ring 3022, the lock block 301, and the tool bit 200.

As shown in fig. 4-14, in some embodiments, support arm 3021 is capable of elastic deformation relative to lock block 301 in the axial direction of pan body 101. When tool 200 is removed, the tool can be pulled or pushed with force, such that the projection presses against support arm 3021 and forces support arm 3021 to elastically deform, such that the projection disengages from support arm 3021 to complete removal of tool 200. In a specific embodiment, the supporting portion 302 (or the supporting arm 3021 and the supporting ring 0322) is made of a flexible material, such as rubber or silicone, to achieve elastic deformation of the supporting portion 302 (or the supporting arm 3021 and the supporting ring 0322). Meanwhile, the silica gel and the rubber are common gasket materials, so that the cost is low and the rubber is easy to obtain. In addition, when the support portion 302 includes the support ring 3022 and the support arm 3021, the support ring 3022 is integrally formed with the support arm 3021, improving the reliability of the connection therebetween.

In some embodiments, the stiffness of support arm 3021 is provided in a staggered gradient in the radially inward direction. For example, support arm 3021 extends radially inward beginning at a first end and ending at a second end. The stiffness of the first end is the greatest and the stiffness of the second end is the least, the stiffness between the first and second ends being in a staggered gradient arrangement. For example, the stiffness may be from large to small, then from small to large, then from large to small, in the direction from the first end toward the second end. With such an arrangement, when the tool 200 is dismounted, the different stiffness regions arranged in a staggered manner can ensure that the supporting arm 3021 has good supporting performance for the protrusion 2011 and even the tool 200, and the supporting arm 3021 is not too hard and can deform, so that the tool 200 can be dismounted.

In further embodiments, the support arm 3021 has a greater stiffness on the side closer to the block 301 than on the side of the support arm 3021 facing away from the block 301. In this way, it is possible to ensure that the support arm 3021 has sufficient support performance to support the projection 2011, and the pressure of the projection 2011 acting on the support arm 3021 can be cushioned, thereby reducing the breakage of the support arm 3021 due to the collision between the projection 2011 and the support arm 3021.

As shown in fig. 8-14, in some embodiments, the support arm 3021 contacts the protrusion 2011 such that a first surface supporting the tool 200 is a sloped or straight surface and a second surface opposite the first surface is a straight or sloped surface. The inclined plane is more convenient to be matched with the cutter 200, the cutter 200 is disassembled and assembled, and the straight plane is arranged to improve the support stability of the cutter 200. Preferably, one surface of the supporting protrusion 2011 of the supporting arm 3021 is a straight surface, and the other surface is a slant surface, so that not only the supporting effect is improved, but also the installation of the tool 200 is facilitated. Alternatively, the first surface may be inclined radially inward to extend downward as an inclined surface, and the second surface may be inclined radially inward to extend upward as an inclined surface, such that the thickness of the support arm 3021 is gradually reduced radially inward, thereby preventing the support ring 3022 from being reversely mounted; and the support arm 3021 is flexible to facilitate easy removal of the tool 200 from the locking cavity 3011.

In other embodiments, the thickness of support arm 3021 may be stepped in the direction extending radially inward. This arrangement allows the protrusions 2011 to jam in movement due to the steps when they contact the support arm 3021, helping to avoid the protrusions 2011 from disengaging themselves under the weight of the tool 200 itself. For example, in the direction of the radially inward extent of support arm 3021, the thickness of support arm 3021 decreases slightly, then increases, and then decreases. The thickness at the extended end of support arm 3021 is still minimal to facilitate good deformability of support arm 3021.

In some embodiments, protrusion 2011 is used to achieve locking of knife 200 to the pan. As shown in fig. 4, 5, 8, 9 and 13, the inner wall of the locking cavity 3011 is provided with a plurality of locking inclined surfaces 3031 at intervals in the circumferential direction, and each locking inclined surface 3031 corresponds to one protrusion 2011. When the knife locking block 301 is screwed tightly relative to the pot body 101, the protrusion 2011 and the locking inclined surface 3031 are squeezed with each other, so that the knife locking block 301 is pressed on the outer part of the bottom 1011 of the pot body 101, and the knife 200 is locked on the pot body 101. At least one support arm 3021 corresponds to a spacing gap 3032 between any adjacent locking ramps 3031.

Taking the number of the protrusions 2011 as three as an example, the three protrusions 2011 are circumferentially and uniformly distributed at intervals. The number of the locking inclined surfaces 3031 is also three, and the three locking inclined surfaces 3031 are uniformly distributed at intervals in the circumferential direction, so that a gap 3032 is formed between any two adjacent locking inclined surfaces 3031. The spacing gap 3032 is provided for disengagement of the projection 2011 with respect to the block 301, i.e., disengagement of the tool 200 with respect to the block 301. Support arm 3021 is configured to correspond to the gap 3032 between any adjacent two of the locking ramps 3031, such that when protrusion 2011 slides off of locking ramp 3031, support arm 3021 carries protrusion 2011 to provide support for tool 200.

In actual use, when the tool 200 is mounted relative to the pot 101, the tool post 201 is first inserted through the bottom 1011 of the pot 101 and extended into the locking cavity 3011 of the locking block 301 beyond the supporting arm 3021, so that the protrusion 2011 on the tool post 201 is located above the locking bevel 3031. Then, the knife locking block 301 is rotated clockwise, the locking inclined surface 3031 and the protrusion 2011 press against each other to press the knife locking block 301 against the outer part of the bottom 1011 of the pot body 101, so that the knife locking block 301 is pressed against the bottom 1011 of the pot body 101. Therefore, the locking of the cutter 200 relative to the pot body 101 is realized through the mutual matching relationship of the locking inclined plane 3031, the protrusion 2011 and the pot bottom 1011 of the pot body 101. At this time, the support ring 3022 mounted on the blade block 301 is pressed between the blade block 301 and the pot bottom 1011.

When the knife is detached, the pot body 101 is inverted (namely, the pot opening faces the tabletop), when the knife locking block 301 is rotated anticlockwise, the protrusion 2011 can be gradually loosened with the knife locking inclined plane 3031, the locking force is gradually reduced along with the rotation of the knife locking block 301, and the knife 200 has a tendency that the relative pot body 101 falls towards the pot opening. After the protrusion 2011 is separated from the locking inclined surface 3031, the protrusion 2011 falls onto the support arm 3021 and is supported on the support arm 3021, so that the falling of the cutter 200 is prevented, and the potential safety hazard is reduced. It will be appreciated that the removal of the knife 200 can be achieved by easily removing the knife 200 with respect to the pan 101, applying a certain force.

The interval gap 3032 between any adjacent locking inclined planes 3031 has a first interval, and the circumferential length of the support arm 3021 is the same as that of the first interval, so that one support arm 3021 is correspondingly arranged between any two adjacent locking inclined planes 3031, and after the protrusion 2011 is separated from the locking inclined planes 3031, the protrusion can directly fall on the support arm 3021, so as to support the tool 200.

In yet another embodiment, as shown in fig. 11, the knife locking structure 300 further comprises a locking ring 303 installed in the locking cavity 3011 of the knife locking block 301, and the locking ring 303 can rotate synchronously with the knife locking block 301. The inner wall of the locking ring 303 is provided with a plurality of locking slopes 3031 at intervals in the circumferential direction. The support ring 3022 is mounted in a mounting slot 3012 in the block 301 and the support arm 3021 extends radially inward and beyond the edge of the clamp ring 303. The interval gap 3032 between any two adjacent locking inclined surfaces 3031 has a second distance, and the circumferential length of the supporting arm 3021 is the same as that of the second distance, so that one supporting arm 3021 is correspondingly arranged between any two adjacent locking inclined surfaces 3031.

In addition, the radial extension length of the support arm 3021 is equal to the radial extension length of the locking bevel 3031. With this arrangement, the projection 2011 can be surely dropped on the corresponding support arm 3021 directly after the lock state is released with respect to the lock slope 3031, thereby supporting the tool 200.

In actual use, when the knife 200 is mounted relative to the pot body 101, the knife holder 201 passes through the bottom 1011 of the cooking cup 100 and extends into the locking ring 303 beyond the supporting arm 3021, so that the protrusion 2011 on the knife holder 201 is located above the locking inclined plane 3031. Then the knife locking block 301 is rotated clockwise, the locking ring 303 and the knife locking block 301 rotate synchronously, and the locking inclined surface 3031 and the protrusion 2011 are pressed mutually, so that the knife locking block 301 presses the bottom 1011 of the pot body 101. Therefore, the locking of the cutter 200 relative to the pot body 101 is realized through the mutual matching relationship of the locking inclined plane 3031, the protrusion 2011 and the pot bottom 1011 of the pot body 101. At this time, the support ring 3022 attached to the blade block 301 is pressed between the blade block 301 and the pan bottom 1011.

When the knife is detached, the pot body 101 is inverted (namely, the pot opening faces the table top), when the knife locking block 301 is rotated anticlockwise, the protrusion 2011 can be gradually loosened from the locking inclined surface 3031, and the locking force is gradually reduced along with the rotation of the knife locking block 301, so that the knife 200 has a tendency of falling towards the pot opening relative to the pot body 101. After the protrusion 2011 is separated from the locking inclined surface 3031, the protrusion 2011 falls onto the support arm 3021 and is supported on the support arm 3021, so that the falling of the tool 200 is prevented, and the potential safety hazard is reduced. It will be appreciated that the removal of the knife 200 can be achieved by easily removing the knife 200 with respect to the pan 101, applying a certain force.

As shown in fig. 3, 4 and 8, in another embodiment, the tool seat 201 is disposed in a prism structure (e.g., a hexagonal prism), in which case the tool mounting hole 1012 disposed on the pot 101 is also disposed in a corresponding polygon (e.g., a hexagon), and the tool mounting hole 1012 is disposed with a mounting opening corresponding to the protrusion 2011. The polygonal fit of the tool holder 201 and the tool receiving aperture 1012 prevents the tool holder 201 from rotating when the cutter shaft 202 rotates the cutter body 203. This solves the problem of the tool holder 201 rotating with the arbor 202 in a very simple manner, simplifying the construction of the tool 200. Meanwhile, during the mounting and dismounting of the tool 200, only the protrusion 2011 needs to be aligned with the mounting opening, which greatly simplifies the mounting and dismounting of the tool 200.

In an embodiment not shown, the protrusion 2011 may not be used to lock the knife 200 with the pot, but rather to prevent the knife holder 201 from rotating. For example, the pot holder 102 is provided with a structure that engages with the protrusion 2011, so that when the cutter shaft 202 rotates the cutter body 203, the rotation of the cutter holder 201 is suppressed. In this case, an additional locking protrusion may be provided on the tool holder 201 to cooperate with the locking bevel 3031 on the blade locking block 301 to lock the blade. At this time, the projection 2011 or the locking projection can be in contact with the support arm 3021, and the support arm 3021 can bear the projection to prevent the cutter 200 from directly falling off.

In summary, in the cutter locking structure 300, the supporting portion 302 is disposed on the cutter locking block 301, and the supporting portion 302 is in contact with the protrusion 2011 on the cutter holder 201, so as to support the cutter 200, thereby effectively avoiding the problem that the cutter 200 is directly separated from the cutter locking block 301. The support portion 302 has a support arm 3021, and the support arm 3021 has a deformation performance while having a support performance, so that the support arm 3021 can support the knife 200 and can facilitate a user to separate the knife 200 from the knife block 301 through deformation.

As shown in fig. 1-13, in some embodiments, lock block 301 is provided with an extension arm 3015, and extension arm 3015 can extend from the sidewall of pan body 101. In one embodiment, a handle block 3016 is provided at the extended end of the extension arm 3015 to facilitate the user to rotate the lock blade block 301 by holding the handle block 3016, which enables the lock blade block 301 to be rotated at the laterally outer portion of the pan body 101. In another embodiment, the sidewall of pot 101 is provided with an arcuate aperture 1026 extending along the circumference of pot 101, and extension arm 3015 is able to rotate within arcuate aperture 1026. Preferably, a receiving groove 1027 recessed radially inwards is formed in the side wall of the pot body 101, an arc-shaped hole 1026 is formed in the bottom of the receiving groove 1027, and the handle block 3016 is received in the receiving groove 1027, so as to prevent the handle block 3016 from being accidentally touched to cause the loosening of the cutter.

When the knife is to be disassembled, a user can hold the extending part (for example, the handle block 3016) of the extending arm 3015 from the outside of the side wall of the pot body 101 to rotate the knife locking block 301, so as to lock and unlock the knife 200. Under the condition, the cutter 200 can be disassembled and assembled without inverting the pot body 101 (namely, the pot body 101 is placed rightly), the operation is more convenient, the problem that the cutter 200 falls off relative to the pot body 101 can be avoided, and the use safety of the food processor is improved.

It should be noted that, for those skilled in the art, without departing from the spirit of the present invention, several variations and modifications can be made, which are within the scope of the present invention.
