Description

[0001] This application is a divisional application of the Chinese patent application with the application date of July 19, 2019, application number "201910653421.7", and invention name "Food cooking machine, knife assembly mounting structure and mixing cup", all contents of which are incorporated into this application by reference. Technical Field

[0002] The present invention relates to the technical field of household electrical appliances, and in particular to a knife assembly mounting structure of a food processor, a mixing cup including the knife assembly mounting structure, and a food processor including the mixing cup. Background Art

[0003] At present, the knife set of food processors such as wall breakers on the market is fixed in a way that the knife set passes through the bottom of the cup, and then a nut or a spiral structure similar to a nut is used to lock the knife set at the bottom of the cup. When removing the knife set, the bottom locking nut needs to be loosened. Therefore, when disassembling and assembling the knife set, either manual operation is chosen, which is time-consuming and laborious, or additional tools are required, which is inconvenient. Summary of the invention

[0004] In order to solve at least one of the above technical problems, an object of the present invention is to provide a knife assembly installation structure for a food processor.

[0005] Another object of the present invention is to provide a blending cup including the above-mentioned blade assembly mounting structure.

[0006] Another object of the present invention is to provide a food processor comprising the mixing cup.

[0007] In order to achieve the above-mentioned purpose, the technical solution of the first aspect of the present invention provides a knife group installation structure of a food processing machine, including: a container bottom, the bottom wall of the container bottom is provided with a mounting hole; a knife holder installed at the mounting hole and used for installing the knife of the food processing machine; a locking component installed on the container bottom, cooperating with the knife holder, suitable for reciprocating between a knife removal position and a knife locking position relative to the container bottom, and locking the knife holder to fix the knife holder when moving to the knife locking position, and unlocking the knife holder to release the knife holder when moving to the knife removal position.

[0008] The knife assembly installation structure provided by the technical solution of the first aspect of the present invention has an installation hole and a locking component on the bottom wall of the container bottom. The locking component acts as a disassembly tool. The knife assembly can be installed on or removed from the container bottom by operating the locking component, which not only avoids the time-consuming and labor-intensive manual operation in the prior art, but also does not require the use of other tools for operation. Therefore, the difficulty of disassembly and assembly of the knife assembly is significantly reduced, which is conducive to the rapid disassembly and assembly of the knife assembly. At the same time, since the locking component is directly installed on the bottom of the container, it can reciprocate between the knife disassembly position and the knife locking position relative to the bottom of the container. Therefore, the locking component will not be separated from the bottom of the container during use. This can prevent the locking component from being lost or confused with other tools, thereby improving the reliability of the use of the locking component, and there is no need to re-assemble and position the locking component every time the knife assembly is disassembled, thereby improving the convenience of use of the locking component, making the disassembly and assembly of the knife assembly more labor-saving and convenient. In addition, the locking component is used to lock or unlock the tool holder, eliminating the locking nut in the prior art. For products with forward and reverse tool rotations, this can prevent the nut from loosening and causing the tool holder to loosen when the tool rotates in one direction, thereby improving the product's reliability.

[0009] It is worth mentioning that the bottom of the container can be the bottom of the blending cup of the food processor. In this case, the cup body of the blending cup is a structure with open ends, and a machine base is also provided under the blending cup, and the machine base and the blending cup can be detachably matched, wherein a sealing structure can be provided between the bottom of the container and the lower end of the cup body to ensure the sealing performance, and the bottom of the container can also be integrally connected to the cup body; or, the bottom of the container is the bottom of the blending cup, and the blending cup includes a cup body with a accommodating cavity, the bottom of the container is located below the accommodating cavity, and a heating plate and other structures are provided between the bottom of the container and the cup body. In this case, the bottom of the container can be connected to the side wall of the cup body through a side panel, and from the appearance, the side panel constitutes a part of the side wall of the blending cup, the bottom of the container is the bottom of the blending cup, and the side panel and the bottom of the container can be an integral structure or a split structure; or, the bottom of the container can also be a part of the machine base of the food processor, in which case the blending cup can be a structure with an open upper end and a perforated structure provided on the bottom of the cup, and the blending cup is fixedly connected to the machine base and cannot be separated during use.

[0010] In addition, the knife assembly installation structure in the above technical solution provided by the present invention may also have the following additional technical features:

[0011] In the above technical solution, the locking component is a wrench, and the wrench is rotatably connected to the bottom of the container.

[0012] The locking component is a wrench, which is rotatably connected to the bottom of the container (for example, by a hinge connection or by a shaft and a shaft hole, etc.), to ensure that the wrench can be rotated to realize its function of disassembling the knife set. Since the wrench can use the principle of a lever, it can significantly reduce the operating force, thereby further reducing the difficulty of disassembling the knife set, making the disassembly of the knife set more labor-saving and convenient.

[0013] Of course, the locking component is not limited to a wrench, and can also be in other forms. For example: the locking component is similar in shape to a wrench, but is slidably connected to the bottom of the container, and when sliding to the knife locking position, it engages with the locking portion on the knife holder to achieve locking, and when sliding in the reverse direction, it disengages from the locking portion on the knife holder to achieve unlocking; or, the locking component is a rotating ring, and a slot is provided in the rotating ring, and a cam is provided on the knife holder, and when the cam is rotated until it engages in the slot, locking is achieved, and when the cam is rotated until it disengages from the slot, unlocking is achieved.

[0014] In the above technical solution, one of the tool holder and the wrench is provided with a locking protrusion, and the other is provided with a locking groove, and the locking protrusion is suitable for inserting and matching with the locking groove.

[0015] The locking protrusion and the locking groove are used to lock or unlock the knife holder by the locking component. The structure and principle are relatively simple and easy to implement. The locking protrusion can be set on the knife holder and the locking groove can be set on the bottom of the container. The positions can also be swapped, with the locking protrusion set on the bottom of the container and the locking protrusion set on the knife holder.

[0016] In the above technical solution, the wrench is provided with a locking portion having an opening in the circumferential direction, the locking portion surrounds the locking groove, and the locking protrusion is provided on the wall surface of the tool holder.

[0017] The wrench is provided with a locking portion, and the locking portion has an opening in the circumference, so that the locking portion can enclose a locking groove, and in the process of rotating with the wrench, the direction of the notch of the locking groove also rotates, and then cooperates with the locking protrusion to realize the function of locking or unlocking the knife seat. As for the specific shape of the locking portion, there is no restriction. For example, the locking portion with an opening in the circumference can be in a C-shape, U-shape, V-shape, etc., as long as there is a notch, the locking groove can be defined. Optionally, the width of the notch of the locking groove is less than the maximum width of the internal space of the locking groove. For example, the locking portion is in a C-shape or other shape with a relatively small notch, and the notch of the locking groove has a tendency to shrink relative to the internal space of the locking groove, so that the locking protrusion inserted into the locking groove can be restricted from slipping out of the locking groove in the reverse direction, which is conducive to improving the locking reliability of the knife seat. Accordingly, the locking protrusion is arranged on the knife seat, and is arranged on the wall surface of the knife seat, which can prevent the locking protrusion from interfering with the relevant structure installed on the knife shaft below the knife seat, and the design is relatively reasonable.

[0018] In the above technical solution, the wrench includes a rotating connection portion rotatably connected to the bottom of the container, and the locking portion is arranged at the rotating connection portion; wherein, when the wrench is rotated to the knife removal position, the opening of the locking groove faces upward so that the locking protrusion can be inserted into the locking groove from top to bottom or removed from the locking groove from bottom to top, and when the wrench is rotated to the knife locking position, the opening of the locking groove is oriented at an angle within a range of 30° to 150° relative to the opening facing upward, so as to limit the locking protrusion from falling out of the locking groove.

[0019] Since the locking part applies a locking force to the knife seat, arranging the locking part at the rotating connection part of the wrench is beneficial to increase the length of the force arm when rotating the wrench, further reduce the operating force applied when rotating the wrench, and further reduce the difficulty of disassembling and assembling the knife group.

[0020] Furthermore, when installing the knife set, the wrench is rotated to the knife removal position. Since the opening of the locking groove faces upward, the knife holder can be installed from top to bottom at the mounting hole, so that the locking protrusion is inserted into the locking groove from top to bottom, and then the wrench is rotated so that the opening of the locking groove faces other directions, such as sideways or downward, so as to prevent the locking protrusion from falling out of the locking groove, thereby playing the role of locking the knife holder. When disassembling the knife set, the wrench is rotated in the opposite direction to the knife removal position. At this time, the opening of the locking groove faces upward, and the knife holder can be pulled out upward freely, so that the locking protrusion falls out of the locking groove, thereby playing the role of unlocking the knife holder. Since when the wrench is in the knife removal position, the locking protrusion will remain in the locking groove under the action of gravity without being affected by external forces, so that the knife holder will stay steadily in the current position, so that the knife holder will not fall instantly, thereby preventing the knife holder from hitting the table or even injuring the user, thereby improving the user experience.

[0021] Optionally, when the wrench is rotated to the knife locking position, the angle of the opening direction of the locking groove relative to the upward opening is in the range of 30° to 150°, that is, the angle between the opening direction of the locking groove when the wrench is in the knife locking position and the opening direction when the wrench is in the knife disassembling position is in the range of 30° to 150°, so that the interference effect exerted by the groove wall of the locking groove on the locking protrusion can be used to prevent the locking protrusion from escaping from the locking groove, thereby achieving the function of locking the knife seat. Of course, the angle between the opening direction of the locking groove when the wrench is in the knife locking position and the opening direction of the wrench when the wrench is in the knife disassembling position is not limited to the above range and can be adjusted as needed.

[0022] In the above technical solution, the rotating connection part includes a limit plate and a rotating shaft, one end of the rotating shaft is connected to the locking part, and the other end of the rotating shaft is connected to the limit plate; a mounting plate is provided at the bottom of the container, and the mounting plate is provided with an axial hole adapted to the rotating shaft, the rotating shaft is plugged into the axial hole, and the limit plate and the locking part are respectively located on both sides of the mounting plate, for limiting the rotating shaft from slipping out of the axial hole.

[0023] The rotating connection part includes a limit plate and a rotating shaft, and the rotating shaft is inserted into the shaft hole on the mounting plate at the bottom of the container to realize the rotating connection between the wrench and the bottom of the container; the two ends of the rotating shaft are respectively connected to the limit plate and the locking part, and the limit plate and the locking part are respectively located on both sides of the mounting plate, and the size of the limit plate and the locking part is larger than the cross-sectional size of the shaft hole, so that the rotating shaft can be limited from slipping out of the shaft hole, thereby improving the connection reliability between the wrench and the bottom of the container.

[0024] In the above technical solution, the mounting plate includes a first sub-plate and a second sub-plate connected to the first sub-plate, the first sub-plate is provided with a first groove, the second sub-plate is provided with a second groove, and the first groove and the second groove are combined to form the shaft hole.

[0025] The mounting plate is split into a first sub-plate and a second sub-plate, and the first groove on the first sub-plate and the second groove on the second sub-plate are assembled to form an axial hole. When assembling, the rotating shaft can be first clamped in the first groove, and then the second sub-plate is fixedly connected to the first sub-plate, so that the plug-in fit between the rotating shaft and the axial hole can be achieved. In this way, the wrench can be designed as an integrated structure, which is conducive to improving the strength and reliability of the wrench. Of course, the assembly between the wrench and the bottom of the container is not limited to the above scheme. For example: the mounting plate can also be designed as an integrated structure, the limit plate and the rotating shaft can be designed as a split structure, the rotating shaft is first inserted into the axial hole, and then the limit plate is fixed on the rotating shaft; or the rotating shaft and the locking part can be designed as a split structure, the rotating shaft is first inserted into the axial hole, and then the locking part is fixed on the rotating shaft. Among them, only the mounting plate part at the bottom of the container can be designed as a split structure, or the bottom of the container can be designed as a split structure as a whole.

[0026] In the above technical solution, the lateral width of the locking protrusion is smaller than the longitudinal height of the locking protrusion; and / or the lateral width of the locking protrusion is larger than the width of the notch of the locking groove; and / or the longitudinal height of the locking protrusion is smaller than the depth of the locking groove.

[0027] If the lateral width of the locking protrusion is smaller than the longitudinal height of the locking protrusion, the locking protrusion forms a long strip structure in the vertical direction. This is conducive to reducing the difficulty of the locking protrusion entering and exiting the locking groove when the knife is removed, thereby further reducing the difficulty of disassembly and assembly of the knife group, and is also conducive to increasing the difficulty of the locking protrusion escaping from the locking groove when the notch of the locking groove is rotated to the side when the knife is locked, thereby improving the locking reliability of the wrench on the knife holder.

[0028] The transverse width of the locking projection is greater than the width of the notch of the locking groove, which is conducive to increasing the difficulty of the locking projection to escape from the locking groove, thereby improving the locking reliability of the wrench to the tool holder. Of course, the transverse width of the locking projection can also be less than or equal to the width of the notch of the locking groove.

[0029] The longitudinal height of the locking protrusion is less than the depth of the locking groove, which ensures that the locking protrusion can be completely located in the locking groove in the vertical direction, thereby increasing the difficulty of the locking protrusion escaping from the locking groove and further improving the locking reliability of the wrench to the tool holder.

[0030] In the above technical solution, at least a portion of the locking portion is formed as an elastic arm; and / or the locking portion is provided with a guiding slope, which extends to the notch of the locking groove to guide the locking protrusion into the locking groove.

[0031] At least a portion of the locking portion is formed as an elastic arm, so that the notch of the locking groove can be elastically retracted, thereby reducing the difficulty of the locking protrusion entering and exiting the locking groove, thereby further reducing the difficulty of disassembling and assembling the knife set.

[0032] The locking portion is provided with a guiding bevel, and the guiding bevel is used to guide the locking protrusion into the locking groove, which is beneficial to improve the smoothness of the locking protrusion entering the locking groove, thereby further reducing the difficulty of installing the knife group.

[0033] In the above technical solution, the groove wall of the locking groove is constructed as a cylindrical surface with a notch which is arranged concentrically with the rotating connection part, and the locking protrusion is provided with an arc surface which is adapted to the groove wall of the locking groove; and / or the locking protrusion is a columnar structure with uniform thickness.

[0034] The groove wall of the locking groove is a cylindrical surface with a notch arranged concentrically with the rotating connection part, which ensures that the groove wall of the locking groove can rotate around its central axis, which reduces the movement amplitude of the locking groove, is conducive to reducing the size of the locking groove, and further simplifies the structure of the wrench, and the notch corresponds to the notch of the locking groove, ensuring that the locking protrusion can enter or escape from the locking groove. Correspondingly, the locking protrusion is provided with an arc surface, which is adapted to the shape of the groove wall of the locking groove, and can play a certain positioning role, preventing the locking protrusion from shaking, shifting, etc. in the locking groove, thereby improving the locking reliability of the wrench to the tool holder, and at the same time, it can also play a certain guiding role, so that the locking protrusion can rotate relatively along the groove wall of the locking groove, so that the groove wall of the locking groove can rotate smoothly relative to the locking protrusion when the wrench rotates, so as to further reduce the difficulty of disassembling and assembling the tool set. Of course, the groove wall of the locking groove is not necessarily arranged concentrically with the rotating connection part, and the groove wall of the locking groove is not necessarily a cylindrical surface, as long as it is ensured that the locking groove can be entered by the locking protrusion and can limit the locking protrusion from escaping after the wrench rotates a certain angle.

[0035] The locking protrusion is a columnar structure with uniform thickness, which is relatively regular in structure, easy to process and form, and also helps to simplify the structure of the wrench. Specifically, the contour line of the cross section of the locking protrusion along the vertical direction includes two straight line segments parallel to each other and two arc segments arranged oppositely, so that the locking protrusion has two cylindrical surfaces and two planes, and the two cylindrical surfaces can rotate with the groove wall of the locking groove to improve the smoothness of the rotation of the wrench.

[0036] In any of the above technical solutions, the rotation range of the wrench from the tool removal position to the tool locking position is within the range of 30° to 150°.

[0037] When rotating from the knife disassembly position to the knife locking position, the rotation amplitude of the wrench is within the range of 30° to 150°, which not only avoids the situation that the locking of the knife holder is unreliable due to the rotation amplitude being too small, but also avoids the situation that the bottom size of the container is greatly increased due to the rotation amplitude being too large, which is beneficial to reducing the bottom size of the container. At the same time, for the scheme in which the knife holder and the wrench are respectively provided with a locking protrusion and a locking groove, the angle between the opening directions of the locking groove in the knife disassembly position and the knife locking position is also within the range of 30° to 150°, which can prevent the locking protrusion from falling out of the locking groove in the knife locking position, and play a reliable role in locking the knife. Of course, the rotation amplitude of the wrench is not limited to the above range, and can be adjusted as needed in the actual production process, such as 20°, 180°, etc.

[0038] In the above technical solution, when rotating from the tool removing position to the tool locking position, the rotation range of the wrench is 80° to 100°, or the rotation range of the wrench is 90°.

[0039] The rotation range of the wrench from the knife removal position to the knife locking position is within the range of 80° to 100°. Furthermore, the rotation range of the wrench from the knife removal position to the knife locking position is 90°, which is in line with the user's operating habits. At the same time, for the above-mentioned scheme in which the knife holder and the wrench are respectively provided with a locking protrusion and a locking groove, the openings of the locking grooves are oriented perpendicular to each other in the knife removal position and the knife locking position, which helps prevent the locking protrusion from falling out of the locking groove in the knife locking position, thereby improving the locking reliability of the wrench to the knife holder. Of course, the rotation range of the wrench is not limited to 90°, for example, it can also be 45°, 60°, 135°, etc.

[0040] In any of the above technical solutions, when the wrench is in the knife removing position, a portion of the wrench protrudes from the bottom of the container; and / or, when the wrench is in the knife locking position, the wrench is completely hidden inside the bottom of the container.

[0041] When the wrench is in the tool removal position, a portion of the wrench protrudes from the bottom of the container, making it convenient for the user to hold the protruding portion of the wrench to select the wrench without being easily interfered by the bottom of the container and the structure installed on the bottom of the container, thereby reducing the difficulty of installation.

[0042] When the wrench is in the knife locking position, the wrench is completely hidden inside the bottom of the container, which makes the appearance of the product more regular and improves the aesthetics of the product; at the same time, this is conducive to the assembly between the bottom of the container and the machine base or other structures, and also makes it easy for the bottom of the container to be placed flat on the table when used as the bottom of the food processor, thereby preventing the wrench from interfering with other structures of the food processor or the table.

[0043] In addition, for the solution in which a portion of the wrench protrudes from the bottom of the container when the wrench is in the knife removal position, and the wrench is completely hidden inside the bottom of the container when the wrench is in the knife locking position, the positional relationship between the wrench and the bottom of the container can also serve as a certain reminder. For example: during the knife locking process, if the wrench is not completely hidden inside the bottom of the container, it indicates that the wrench has not been rotated into place and the locking of the knife holder is not reliable enough. During the knife removal process, if a portion of the wrench does not protrude from the bottom of the container, it indicates that the wrench has not been rotated into place and the knife holder has not been completely unlocked.

[0044] In any of the above technical solutions, a limiting portion is provided on the wrench, and a limiting matching portion is provided on the bottom of the container. When the wrench is located at the knife removing position and the knife locking position, the limiting portion and the limiting matching portion are stop-matched to limit the rotation range of the wrench.

[0045] The rotation range of the wrench is limited by the stop cooperation between the limiting part and the limiting cooperation part, which will produce a sense of being in place during the process of disassembling the tool assembly, thereby playing a role in assembly positioning, and at the same time preventing the wrench from continuing to rotate after being rotated into place, thereby improving the reliability of use.

[0046] In the above technical solution, one of the limiting portion and the limiting matching portion is a limiting protrusion, and the other is a limiting groove.

[0047] The rotation range of the wrench is limited by the stop-and-stop cooperation between the limit protrusion and the limit groove. The structure and principle are relatively simple and easy to implement. The limit protrusion can be set on the wrench and the limit groove can be set on the bottom of the container; the positions can also be swapped, the limit protrusion can be set on the bottom of the container, and the limit groove can be set on the wrench. Of course, the limit part and the limit cooperation part are not limited to the form of the limit protrusion and the limit groove. For example, the stop protrusion can also be stopped and cooperated with the stop protrusion, or the stop surface can be stopped and cooperated with the stop protrusion.

[0048] In the above technical solution, the number of the limiting parts is two, the number of the limiting matching part is one, and the two limiting parts respectively cooperate with the limiting matching part when the wrench is located at the tool removing position and the tool locking position.

[0049] Two limiting parts are arranged on the wrench, and only one limiting matching part is arranged on the bottom of the container. Compared with the scheme of two limiting parts and two limiting matching parts, the number of limiting matching parts is reduced by one, and the structure of the bottom of the container is simplified. Of course, the number of limiting parts and limiting matching parts is not limited to the above scheme, for example, the number of limiting parts and limiting matching parts can also be two respectively, or the number of limiting parts can be one and the number of limiting matching parts can be two, or other schemes can be adopted.

[0050] In the above technical solution, an elastic portion is provided on the bottom of the container, and the limiting matching portion is arranged on the elastic portion.

[0051] An elastic part is arranged on the bottom of the container, and the limit matching part is arranged on the elastic part. This not only makes it easy to utilize the restoring elastic force of the elastic part to improve the stopping reliability of the limit part and the limit matching part, but also makes it easy to utilize the elastic deformation ability of the elastic part to reduce the difficulty of disengagement between the limit part and the limit matching part, thereby further reducing the difficulty of rotating the wrench, and further reducing the difficulty of disassembling and assembling the knife group.

[0052] In the above technical solution, the elastic portion is V-shaped, and the limiting matching portion is arranged at the V-shaped tip of the elastic portion.

[0053] The elastic part is V-shaped, and the limiting matching part is arranged at the tip of the V-shape, which is beneficial to increasing the elastic deformation capacity of the elastic part and balancing the force of the elastic part, thereby improving the reliability of the elastic part.

[0054] In the above technical solution, the limiting portion is arranged at the rotating connection portion of the wrench.

[0055] Since the limiting part applies a stop fit force to the bottom of the container, the limiting part is arranged at the rotating connection part of the wrench, which is beneficial to increase the length of the force arm when rotating the wrench, reduce the operating force applied when rotating the wrench, and further reduce the difficulty of disassembling and assembling the knife group. At the same time, the limiting part rotates around the rotation axis of the rotating connection part, which reduces the movement range of the limiting part, which is beneficial to reducing the size of the wrench and the bottom of the container, thereby simplifying the structure of the wrench and the bottom of the container.

[0056] In the above technical solution, the rotating connection portion is located at the end of the wrench, and includes an inner plate and a circular outer plate parallel to each other. The inner plate has an opening in the circumference to form a locking portion with an opening in the circumference. The circular outer plate is rotatably connected to the bottom of the container, and the limiting fitting portion is at least arranged on the circular outer plate.

[0057] The rotating connection part is located at the end of the wrench, which is conducive to increasing the length of the force arm when rotating the wrench, thereby reducing the operating force applied when rotating the wrench, and further reducing the difficulty of disassembling and assembling the knife group. Specifically, the rotating connection part includes an inner plate with an opening in the circumferential direction and a circular outer plate, and the inner plate and the circular outer plate are parallel to each other to form a double-layer structure, which is conducive to improving the strength and reliability of the wrench. Among them, the inner plate with an opening in the circumferential direction forms a locking part with an opening in the circumferential direction, so that the locking part is surrounded by a locking groove, which cooperates with the locking protrusion on the knife holder to lock or unlock the knife holder, and the circular outer plate is rotatably connected to the bottom of the container to realize the connection function of the wrench and the bottom of the container, and the limiting matching part is at least arranged on the circular outer plate (for example, it can also be arranged on the circular outer plate and the inner plate or other structures at the same time), so that the limiting part and the locking part keep synchronous rotation, so that when the wrench is rotated to the knife disassembly position and the knife locking position, the locking groove cooperates with the locking protrusion, and the limiting part also just stops and cooperates with the limiting matching part.

[0058] In any of the above technical solutions, the number of the locking protrusions is two, the two locking protrusions are symmetrically arranged at 180° about the central axis of the knife seat, the number of the locking grooves is equal to the number of the locking protrusions and corresponds one to one; and / or, the wrench is U-shaped, including two rotating arms parallel to each other and a connecting arm connecting the two rotating arms, the two rotating arms are rotatably connected to the bottom of the container at one end away from the connecting arm, and the two rotating arms are respectively provided with the locking protrusions or the locking grooves.

[0059] There are two locking protrusions, and the two locking protrusions are symmetrically arranged at 180° about the central axis of the tool holder (i.e., the rotation axis of the tool). Accordingly, the number of locking grooves is equal to the number of locking protrusions and corresponds one to one, which is beneficial to the force balance between the tool holder and the wrench, thereby improving the reliability of the product.

[0060] The wrench is U-shaped, including two rotating arms and a connecting arm. The connecting arm is located between the two rotating arms and connects one end of the two rotating arms, while the other end of the two rotating arms is rotatably connected to the bottom of the container. Since the two rotating arms are respectively provided with locking protrusions or locking grooves, the two rotating arms can be driven to rotate synchronously by directly applying force to the connecting arm, so that the two locking protrusions cooperate with the two locking grooves, thereby further reducing the difficulty of disassembling and assembling the knife group; at the same time, the U-shaped structure of the wrench can also avoid other structures on the bottom of the container (such as the lower part of the knife group) to prevent interference during the rotation process. Among them, the rotating arm can adopt a double-layer plate structure, the inner plate away from the end of the connecting arm forms the above-mentioned inner plate, and the outer plate away from the end of the connecting arm forms the above-mentioned circular outer plate; or, the inner plate and the circular outer plate are fitted together to form an integrated structure, and the limiting groove can extend from the circular outer plate to the inner plate. Of course, the connecting arm can also be eliminated to form two wrenches, which are controlled separately.

[0061] In the above technical solution, for the case where the wrench is U-shaped and includes two rotating arms parallel to each other and a connecting arm connecting the two rotating arms, the connecting arm extends in a direction deviating from the length direction of the rotating arm to form a handle, and an obtuse angle is formed between the handle and the rotating arm; a accommodating space is provided at the bottom of the container, and when the wrench is in the knife locking position, the wrench is located in the accommodating space.

[0062] The connecting arm extends in a direction deviating from the length direction of the rotating arm to form a handle, which increases the contact area with the wrench when rotating the wrench, which is beneficial to improving the user's operating feel. At the same time, an obtuse angle is formed between the handle and the rotating arm, which is beneficial to reducing the longitudinal dimension of the wrench when it is tilted relative to the bottom of the container, thereby reducing the longitudinal dimension of the bottom of the container; and a storage space is provided at the bottom of the container. When the wrench locks the knife holder, the wrench is located in the storage space to prevent the wrench from leaking out, thereby improving the aesthetics of the product and improving the reliability of use. When the wrench unlocks the knife holder, the handle is located outside the storage space, which is convenient for the user to operate the wrench.

DETAILED DESCRIPTION

[0096] In order to more clearly understand the above-mentioned purpose, features and advantages of the present invention, the present invention is further described in detail below in conjunction with the accompanying drawings and specific embodiments. It should be noted that the embodiments of the present application and the features in the embodiments can be combined with each other without conflict.

[0097] In the following description, many specific details are set forth to facilitate a full understanding of the present invention. However, the present invention may also be implemented in other ways different from those described herein. Therefore, the protection scope of the present invention is not limited to the specific embodiments disclosed below.

[0098] Refer to the following Figures 1 to 17 The present invention describes a knife assembly mounting structure, a blending cup, and a food processor according to some embodiments of the present invention.

[0099] Embodiment 1

[0100] like Figure 2 , Figure 3 and Figure 4 As shown, the knife assembly installation structure of the food processor provided by the embodiment of the first aspect of the present invention comprises: a container bottom 2, a knife seat 11 and a locking component.

[0101] Specifically, the bottom wall of the container bottom 2 is provided with a mounting hole 24, such as Fig.13 As shown; the knife holder 11 is installed at the installation hole 24, and is used to install the knife 12 of the food processor; the locking component is installed on the container bottom 2, and cooperates with the knife holder 11, and is suitable for reciprocating between the knife removal position and the knife locking position relative to the container bottom 2, and when moving to the knife locking position, the knife holder 11 is locked to fix the knife holder 11 (such as Figure 5 and Figure 6 As shown), and unlock the knife holder 11 to release the knife holder 11 when moving to the knife removal position (as shown Figure 7 and Figure 8 shown).

[0102] The knife assembly installation structure provided by the embodiment of the first aspect of the present invention has an installation hole 24 and a locking component on the bottom wall of the container bottom 2. The locking component serves as a disassembly tool. The knife assembly 1 can be installed on or removed from the container bottom 2 by operating the locking component, which not only avoids the time-consuming and labor-intensive manual operation in the prior art, but also does not require the use of other tools for operation. Therefore, the difficulty of disassembly and assembly of the knife assembly 1 is significantly reduced, which is conducive to the rapid disassembly and assembly of the knife assembly 1. At the same time, since the locking component is directly installed on the container bottom 2, it can reciprocate between the knife disassembly position and the knife locking position relative to the container bottom 2. Therefore, the locking component will not be separated from the container bottom 2 during use, which can prevent the locking component from being lost or confused with other tools, thereby improving the reliability of the use of the locking component, and there is no need to re-assemble and position the locking component every time the knife assembly 1 is disassembled, thereby improving the convenience of the locking component, making the disassembly and assembly of the knife assembly 1 more labor-saving and convenient. In addition, the locking component is used to lock or unlock the tool holder 11, eliminating the locking nut in the prior art. For products with forward and reverse rotation of the tool 12, it can prevent the nut from loosening when the tool 12 rotates in one direction, causing the tool holder 11 to loosen, thereby improving the product's reliability.

[0103] It is worth noting that the container bottom 2 can be the bottom of the mixing cup 4 of the food processor. In this case, the cup body 41 of the mixing cup 4 is a structure with open ends, and a machine base 5 is further provided below the mixing cup 4. The machine base 5 and the mixing cup 4 can be detachably matched, wherein a sealing structure can be provided between the container bottom 2 and the lower end of the cup body 41 to ensure the sealing performance, and the container bottom 2 can also be integrally connected to the cup body 41; or, the container bottom 2 is the bottom of the mixing cup 4, and the mixing cup 4 includes a cup body 41 with a receiving cavity, and the container bottom 2 is located below the receiving cavity, and the container bottom 2 and the cup body 41 are connected in one piece. A heating plate and other structures are provided between the container bottom 2 and the cup body 41. At this time, the container bottom 2 can be connected to the side wall of the cup body 41 through the side panel 42. From the appearance, the side panel 42 constitutes a part of the side wall of the mixing cup 4, and the container bottom 2 is the bottom of the mixing cup 4. The side panel 42 and the container bottom 2 can be an integrated structure or a split structure; or, the container bottom 2 can also be a part of the base 5 of the food processor. At this time, the mixing cup 4 can be a structure with an open upper end and a perforated structure on the bottom of the cup. The mixing cup 4 is fixedly connected to the base 5 and cannot be separated during use.

[0104] Specifically, the locking component is a wrench 3, which is rotatably connected to the bottom 2 of the container. Figure 2 , Figure 5 , Figure 7 and Fig.11 shown.

[0105] The locking component is a wrench 3, which is rotatably connected to the container bottom 2 (for example, by a hinge connection or by a rotation shaft 331 matching an axis hole, etc.), to ensure that the wrench 3 can be rotated to realize its function of disassembling the knife set 1. Since the wrench 3 can use the principle of a lever, the operating force can be significantly reduced, thereby further reducing the difficulty of disassembling the knife set 1, making the disassembly of the knife set 1 more labor-saving and convenient.

[0106] Of course, the locking component is not limited to the wrench 3, and can also be in other forms. For example: the locking component is similar in shape to the wrench 3, but is slidably connected to the bottom 2 of the container, and when sliding to the knife locking position, it is locked by the locking part on the knife seat 11, and when sliding in the reverse direction, it is released from the locking part of the knife seat 11 to achieve unlocking; or the locking component is a rotating ring, and a slot is provided in the rotating ring, and a cam is provided on the knife seat 11, and when the cam is rotated until the cam is inserted into the slot, locking is achieved, and when the cam is rotated until the cam is released from the slot, unlocking is achieved.

[0107] Furthermore, one of the knife holder 11 and the wrench 3 is provided with a locking protrusion 113, and the other is provided with a locking groove 311, and the locking protrusion 113 is suitable for plug-in cooperation with the locking groove 311, such as Figure 6 and Figure 8 shown.

[0108] The locking protrusion 113 cooperates with the locking groove 311 to realize locking or unlocking of the knife holder 11 by the locking component. The structure and principle are relatively simple and easy to implement. The locking protrusion 113 can be set on the knife holder 11 and the locking groove 311 can be set on the container bottom 2; the positions can also be swapped, the locking protrusion 113 can be set on the container bottom 2, and the locking protrusion 113 can be set on the knife holder 11.

[0109] Furthermore, the wrench 3 is provided with a locking portion having an opening in the circumferential direction, and the locking portion is provided with a locking groove 311, such as Figure 6 and Figure 8 As shown, the locking protrusion 113 is arranged on the wall surface of the knife seat 11. Figure 1 and Fig.12 shown.

[0110] The wrench 3 is provided with a locking portion, and the locking portion has an opening in the circumference, so that the locking portion can enclose a locking groove 311, and the direction of the notch of the locking groove 311 also rotates during the rotation of the wrench, thereby cooperating with the locking protrusion to achieve the function of locking or unlocking the knife seat. Correspondingly, the locking protrusion 113 is arranged on the knife seat 11 and on the wall surface of the knife seat 11, which can prevent the locking protrusion 113 from interfering with the relevant structure installed on the knife shaft below the knife seat 11, and the design is relatively reasonable.

[0111] The specific shape of the locking portion is not limited. For example, the locking portion with an opening in the circumferential direction can be in a C-shape, a U-shape, a V-shape, etc. As long as there is a notch, the locking groove 311 can be defined.

[0112] Optionally, the width of the notch of the locking groove 311 is smaller than the maximum width of the internal space of the locking groove 311. For example, the locking portion is C-shaped or has other shapes with relatively smaller notches. In this way, the notch of the locking groove 311 tends to shrink relative to the internal space of the locking groove. This can limit the locking protrusion 113 inserted into the locking groove 311 from escaping from the locking groove 311 in the opposite direction, which is beneficial to improving the locking reliability of the tool holder 11.

[0113] Furthermore, if Figure 6 , Figure 8 and Fig.11 As shown, the wrench 3 includes a rotating connection portion 33 that is rotatably connected to the container bottom 2, and the locking portion is arranged at the rotating connection portion 33; wherein, when the wrench 3 is rotated to the tool removal position, the opening of the locking groove 311 faces upward so that the locking protrusion 113 can be inserted into the locking groove 311 from top to bottom (such as Figure 8 and Fig.10 As shown) or the locking groove 311 is removed from bottom to top, when the wrench 3 is rotated to the knife locking position, the opening of the locking groove 311 is oriented at an angle of 30° to 150° relative to the upward opening to limit the locking protrusion 113 from falling out of the locking groove 311.

[0114] Since the locking part applies a locking force to the tool holder 11, the locking part is arranged at the rotating connection part 33 of the wrench 3, which is beneficial to increase the length of the force arm when rotating the wrench 3, further reduce the operating force applied when rotating the wrench 3, and further reduce the difficulty of disassembly and assembly of the tool set 1.

[0115] Furthermore, when installing the knife set 1, the wrench 3 is rotated to the knife disassembly position. Since the opening of the locking groove 311 faces upward, the knife holder 11 can be installed from top to bottom at the mounting hole 24, so that the locking protrusion 113 is inserted into the locking groove 311 from top to bottom, and then the wrench 3 is rotated so that the opening of the locking groove 311 faces other directions, such as sideways or downward, so as to prevent the locking protrusion 113 from being reversely disengaged from the locking groove 311 from bottom to top, thereby locking the knife holder 11. When disassembling the knife set 1, the wrench 3 is rotated in the opposite direction to the knife disassembly position. At this time, the opening of the locking groove 311 faces upward, and the knife holder 11 can be freely pulled out upward, so that the locking protrusion 113 is disengaged from the locking groove 311, thereby unlocking the knife holder 11. Because when the wrench 3 is in the knife removal position, without being affected by external forces, the locking protrusion 113 will remain in the locking groove 311 under the action of gravity, so that the knife holder 11 will stay firmly in the current position, and the knife holder 11 will not fall instantly, thereby preventing the knife holder 11 from hitting the table or even injuring the user, thereby improving the user experience.

[0116] Optionally, when the wrench 3 is rotated to the knife locking position, the angle of the opening direction of the locking groove 311 relative to the upward opening is in the range of 30° to 150°, that is, the angle between the opening direction of the locking groove 311 when the wrench 3 is in the knife locking position and the opening direction when the wrench 3 is in the knife disassembling position is in the range of 30° to 150°, so that the interference effect exerted by the groove wall of the locking groove 311 on the locking protrusion 113 can be used to prevent the locking protrusion 113 from escaping from the locking groove 311, thereby achieving the function of locking the knife seat. Of course, the angle between the opening direction of the locking groove 311 when the wrench 3 is in the knife locking position and the opening direction of the wrench 3 when the wrench 3 is in the knife disassembling position is not limited to the above range and can be adjusted as needed.

[0117] Furthermore, if Fig.10 As shown, the rotating connection part 33 includes a limit plate 332 and a rotating shaft 331, one end of the rotating shaft 331 is connected to the locking part, and the other end of the rotating shaft 331 is connected to the limit plate 332; the bottom 2 of the container is provided with a mounting plate, and the mounting plate is provided with an axial hole adapted to the rotating shaft 331, the rotating shaft 331 is plug-fitted into the axial hole, and the limit plate 332 and the locking part are respectively located on both sides of the mounting plate, for limiting the rotating shaft 331 from slipping out of the axial hole.

[0118] The rotating connection part 33 includes a limit plate 332 and a rotating shaft 331. The rotating shaft 331 is inserted into the axial hole on the mounting plate of the container bottom 2 to realize the rotating connection between the wrench 3 and the container bottom 2; the two ends of the rotating shaft 331 are respectively connected to the limit plate 332 and the locking part, and the limit plate 332 and the locking part are respectively located on both sides of the mounting plate, and the size of the limit plate 332 and the locking part is larger than the cross-sectional size of the axial hole, so that the rotating shaft 331 can be limited from slipping out of the axial hole, thereby improving the connection reliability between the wrench 3 and the container bottom 2.

[0119] The mounting plate includes a first sub-plate and a second sub-plate connected to the first sub-plate, the first sub-plate is provided with a first groove, the second sub-plate is provided with a second groove, and the first groove and the second groove are combined to form an axial hole.

[0120] The mounting plate is split into a first sub-plate and a second sub-plate, and the first groove on the first sub-plate and the second groove on the second sub-plate are assembled to form an axial hole. When assembling, the rotating shaft 331 can be first clamped in the first groove, and then the second sub-plate is fixedly connected to the first sub-plate, so that the plug-in fit between the rotating shaft 331 and the axial hole can be achieved. In this way, the wrench 3 can be designed as an integrated structure, which is conducive to improving the strength and reliability of the wrench 3. Of course, the assembly between the wrench 3 and the bottom 2 of the container is not limited to the above scheme. For example: the mounting plate can also be designed as an integrated structure, and the limiting plate 332 and the rotating shaft 331 are designed as a split structure, the rotating shaft 331 is first inserted into the axial hole, and then the limiting plate 332 is fixed on the rotating shaft 331; or the rotating shaft 331 and the locking part are designed as a split structure, the rotating shaft 331 is first inserted into the axial hole, and then the locking part is fixed on the rotating shaft 331. Among them, only the mounting plate part of the bottom 2 of the container can be designed as a split structure, or the bottom 2 of the container can be designed as a split structure as a whole.

[0121] Furthermore, the lateral width W of the locking protrusion 113 is smaller than the longitudinal height H of the locking protrusion 113. Figure 8 and Fig.12 shown.

[0122] The lateral width W of the locking protrusion 113 is smaller than the longitudinal height H of the locking protrusion 113, and the locking protrusion 113 forms a long strip structure in the vertical direction. This is conducive to reducing the difficulty of the locking protrusion 113 entering and exiting the locking groove 311 when the knife is removed, thereby further reducing the difficulty of disassembly and assembly of the knife group 1, and is also conducive to increasing the difficulty of the locking protrusion 113 escaping from the locking groove 311 when the notch of the locking groove 311 is rotated to the side when the knife is locked, thereby improving the locking reliability of the wrench 3 to the knife seat 11.

[0123] Furthermore, the lateral width W of the locking protrusion 113 is greater than the width D of the notch of the locking groove 311. Figure 8 shown.

[0124] The lateral width of the locking protrusion 113 is greater than the width of the notch of the locking groove 311, which is conducive to increasing the difficulty of the locking protrusion 113 to escape from the locking groove 311, thereby improving the locking reliability of the wrench 3 to the tool holder 11. Of course, the lateral width of the locking protrusion 113 can also be less than or equal to the width of the notch of the locking groove 311.

[0125] Furthermore, the longitudinal height H of the locking protrusion 113 is smaller than the depth of the locking groove 311. Figure 6and Figure 8 shown.

[0126] The longitudinal height H of the locking protrusion 113 is smaller than the depth of the locking groove 311, ensuring that the locking protrusion 113 can be completely located in the locking groove 311 in the vertical direction, thereby increasing the difficulty of the locking protrusion 113 escaping from the locking groove 311 and further improving the locking reliability of the wrench 3 to the tool holder 11.

[0127] Wherein, at least a part of the locking portion is formed as an elastic arm 312, such as Figure 6 and Figure 8 shown.

[0128] At least a portion of the locking portion is formed as an elastic arm 312, so that the notch of the locking groove 311 can be elastically retracted, thereby reducing the difficulty of the locking protrusion 113 entering and exiting the locking groove 311, thereby further reducing the difficulty of disassembling and assembling the knife set 1.

[0129] Furthermore, the locking portion is provided with a guide slope 3121, such as Figure 6 As shown, the guiding slope 3121 extends to the notch of the locking groove 311 to guide the locking protrusion 113 into the locking groove 311 .

[0130] The locking portion is provided with a guiding inclined surface 3121 , and the guiding inclined surface 3121 is used to guide the locking protrusion 113 into the locking groove 311 , which is beneficial to improve the smoothness of the locking protrusion 113 entering the locking groove 311 , thereby further reducing the difficulty of installing the knife set 1 .

[0131] Furthermore, the groove wall of the locking groove 311 is configured as a cylindrical surface arranged concentrically with the rotating connecting portion 33, such as Fig.11 As shown, the locking protrusion 113 is provided with an arc surface 1131 adapted to the groove wall of the locking groove 311, and the locking protrusion 113 is a columnar structure with uniform thickness, as shown in FIG. Figure 1 shown.

[0132] The groove wall of the locking groove 311 is a cylindrical surface arranged concentrically with the rotating connecting portion 33, which ensures that the groove wall of the locking groove 311 rotates at its center, which reduces the movement amplitude of the locking groove 311, helps to reduce the size of the locking groove 311, and further simplifies the structure of the wrench 3. Accordingly, the locking protrusion 113 is provided with an arc surface 1131, which is adapted to the shape of the groove wall of the locking groove 311, such as Figure 6 and Figure 8As shown, it can play a certain positioning role, preventing the locking protrusion 113 from shaking, shifting, etc. in the locking groove 311, thereby improving the locking reliability of the wrench 3 to the tool holder 11, and it can also play a certain guiding role, so that the locking protrusion 113 can rotate relatively along the groove wall of the locking groove 311, thereby facilitating the groove wall of the locking groove 311 to rotate relative to the locking protrusion 113, so as to further reduce the difficulty of disassembly and assembly of the tool set 1.

[0133] The locking protrusion 113 is a columnar structure with uniform thickness, which is relatively regular and easy to process and form, and is also conducive to simplifying the structure of the wrench 3. Specifically, the contour line of the cross section of the locking protrusion 113 along the vertical direction includes two straight line segments parallel to each other and two arc segments arranged oppositely, such as Figure 6 and Figure 8 As shown, the locking protrusion 113 has two cylindrical surfaces and two flat surfaces. The two cylindrical surfaces can be rotatably matched with the groove wall of the locking groove 311 to improve the smoothness of the rotation of the wrench 3.

[0134] Of course, the groove wall of the locking groove 311 is not necessarily concentric with the rotating connection part 33, and the groove wall of the locking groove 311 is not necessarily a cylindrical surface, as long as the locking groove 311 can allow the locking protrusion 113 to enter and can limit the locking protrusion 113 from coming out after the wrench 3 rotates a certain angle.

[0135] Optionally, the rotation range of the wrench 3 from the tool removal position to the tool locking position is in the range of 30° to 150°.

[0136] From the knife disassembly position to the knife locking position, the rotation amplitude of the wrench 3 is within the range of 30° to 150°, which not only avoids the situation that the locking of the knife holder is unreliable due to the rotation amplitude being too small, but also avoids the situation that the size of the container bottom 2 is greatly increased due to the rotation amplitude being too large, which is conducive to reducing the size of the container bottom 2. At the same time, for the solution in which the locking protrusion 113 and the locking groove 311 are respectively provided on the knife holder and the wrench 3, the angle between the opening directions of the locking groove 311 is also within the range of 30° to 150° when in the knife disassembly position and the knife locking position, which can prevent the locking protrusion 113 from escaping from the locking groove 311 when in the knife locking position, and play a reliable knife locking role. Of course, the rotation amplitude of the wrench 3 is not limited to the above range, and can be adjusted as needed in the actual production process, such as 20°, 180°, etc.

[0137] Furthermore, when rotating from the tool removing position to the tool locking position, the rotation range of the wrench 3 is 80° to 100°.

[0138] The rotation range of the wrench 3 from the knife removal position to the knife locking position is in the range of 80° to 100°, which further improves the reliability of the knife locking and is beneficial to further adjust the size of the bottom 2 of the small container.

[0139] In one embodiment, the rotation range of the wrench 3 from the tool removal position to the tool locking position is 90°. Figure 6 and Figure 8 shown.

[0140] The rotation range of the wrench 3 from the knife disassembly position to the knife locking position is 90°, which is in line with the user's operating habits. At the same time, for the solution in which the locking protrusion 113 and the locking groove 311 are respectively provided on the knife holder 11 and the wrench 3, when in the knife disassembly position and the knife locking position, the opening of the locking groove 311 is perpendicular to each other. Figure 6 and Figure 8 As shown, this helps prevent the locking protrusion 113 from slipping out of the locking groove 311 when the knife is in the locked position, thereby improving the locking reliability of the wrench 3 on the knife holder 11. Of course, the rotation range of the wrench 3 is not limited to 90°, for example, it can also be 45°, 60°, 135°, etc.

[0141] Furthermore, when the wrench 3 is located at the knife removal position, a portion of the wrench 3 protrudes from the container bottom 2, such as Figure 8 , Fig.10 and Fig.16 When the wrench 3 is in the knife locking position, the wrench 3 is completely hidden inside the bottom 2 of the container, as shown in FIG. Figure 6 , Fig. 9 , Fig.15 and Fig.17 shown.

[0142] When the wrench 3 is in the tool removal position, a portion of the wrench 3 protrudes from the container bottom 2, making it convenient for the user to hold the protruding portion of the wrench 3 to select the wrench 3 without being easily interfered by the container bottom 2 and the structure installed on the container bottom 2, thereby reducing the difficulty of installation.

[0143] When the wrench 3 is in the knife locking position, the wrench 3 is completely hidden inside the container bottom 2, making the appearance of the product more regular and improving the aesthetics of the product; at the same time, this is not only conducive to the assembly between the container bottom 2 and the machine base 5 or other structures, but also convenient for the container bottom 2 to be placed flat on the table when serving as the bottom of the food processor, thereby preventing the wrench 3 from interfering with other structures of the food processor or the table.

[0144] In addition, for the solution that when the wrench 3 is in the knife removal position, a part of the wrench 3 protrudes from the container bottom 2, and when the wrench 3 is in the knife locking position, the wrench 3 is completely hidden inside the container bottom 2, the positional relationship between the wrench 3 and the container bottom 2 can also play a certain prompting role. For example: during the knife locking process, when the wrench 3 is not completely hidden inside the container bottom 2, it indicates that the wrench 3 has not been rotated into place, and the locking of the knife holder is not reliable enough. During the knife removal process, when a part of the wrench 3 does not protrude from the container bottom 2, it indicates that the wrench 3 has not been rotated into place, and the knife holder has not been completely unlocked.

[0145] Embodiment 2

[0146] The difference from the first embodiment is that: on the basis of the first embodiment, further, a limiting portion is provided on the wrench 3, and a limiting matching portion is provided on the bottom 2 of the container. When the wrench 3 is located at the knife disassembly position and the knife locking position, the limiting portion and the limiting matching portion are stopped and matched. Fig. 9 and Fig.10 As shown, the rotation range of the wrench 3 is limited.

[0147] The rotation range of the wrench 3 is limited by the stop cooperation between the limiting part and the limiting cooperation part, which will produce a sense of being in place during the process of disassembling the tool assembly 1, thereby playing a role in assembly positioning, and at the same time preventing the wrench 3 from continuing to rotate after being rotated into place, thereby improving the reliability of use.

[0148] Optionally, one of the limiting portion and the limiting matching portion is a limiting protrusion 21, and the other is a limiting groove 315. Fig. 9 and Fig.10 shown.

[0149] The rotation range of the wrench 3 is limited by the stop-and-abutment cooperation between the stop protrusion 21 and the stop groove 315. The structure and principle are relatively simple and easy to implement. The stop protrusion 21 can be set on the wrench 3, and the stop groove 315 can be set on the container bottom 2; or the positions can be swapped, and the stop protrusion 21 can be set on the container bottom 2, and the stop groove 315 can be set on the wrench 3. Of course, the stop portion and the stop-and-abutment cooperation portion are not limited to the form of the stop protrusion 21 and the stop groove 315, for example, the stop protrusion and the stop protrusion can also be stop-and-abutment cooperation or the stop surface and the stop protrusion can also be stop-and-abutment cooperation.

[0150] Furthermore, the number of the limiting parts is two, and the number of the limiting matching parts is one, such as Fig.10 and Fig.11 As shown, the two limiting parts respectively cooperate with the limiting matching part when the wrench 3 is located at the tool removing position and the tool locking position.

[0151] Two limiting parts are provided on the wrench 3, and only one limiting matching part is provided on the container bottom 2. Compared with the scheme of two limiting parts and two limiting matching parts being stopped and matched, the number of limiting matching parts is reduced by one, and the structure of the container bottom 2 is simplified. Of course, the number of limiting parts and limiting matching parts is not limited to the above scheme, for example, the number of limiting parts and limiting matching parts can also be two respectively, or the number of limiting parts can be one and the number of limiting matching parts can be two, or other schemes can be adopted.

[0152] Furthermore, an elastic portion 22 is provided on the bottom 2 of the container, and the limiting matching portion is provided on the elastic portion 22. Fig. 9 and Fig.10 shown.

[0153] An elastic portion 22 is provided on the bottom 2 of the container, and the limit fitting portion is provided on the elastic portion 22. This not only facilitates utilizing the restoring elastic force of the elastic portion 22 to improve the reliability of the stop between the limit portion and the limit fitting portion, but also facilitates utilizing the elastic deformation ability of the elastic portion 22 to reduce the difficulty of disengaging the limit portion and the limit fitting portion, thereby further reducing the difficulty of rotating the wrench 3, and further reducing the difficulty of disassembling and assembling the knife group 1.

[0154] The elastic part 22 is V-shaped, and the limiting matching part is arranged at the V-shaped tip of the elastic part 22. Fig. 9 and Fig.10 shown.

[0155] The elastic part 22 is V-shaped, and the limiting matching part is arranged at the tip of the V-shape, which is beneficial to increasing the elastic deformation ability of the elastic part 22 and balancing the force of the elastic part 22, thereby improving the reliability of the elastic part 22. Of course, the elastic part 22 is not limited to the V-shape, and can also be a columnar, hemispherical or other structure.

[0156] Furthermore, the limiting portion is arranged at the rotating connection portion 33 of the wrench 3, such as Figures 9 to 11 shown.

[0157] Since the limiting part applies a stop-fitting force to the container bottom 2, the limiting part is arranged at the rotating connection part 33 of the wrench 3, which is conducive to increasing the length of the force arm when rotating the wrench 3, reducing the operating force applied when rotating the wrench 3, and further reducing the difficulty of disassembling and assembling the knife assembly 1. At the same time, the limiting part rotates around the rotating axis 331 of the rotating connection part 33, which reduces the movement range of the limiting part, which is conducive to reducing the size of the wrench 3 and the container bottom 2, and further simplifying the structure of the wrench 3 and the container bottom 2.

[0158] Furthermore, the rotating connection portion 33 is located at the end of the wrench 3, and includes an inner plate 313 and a circular outer plate 314 which are parallel to each other. Fig. 9 and Fig.10As shown, the inner plate 313 has an opening in the circumference to form a locking portion with an opening in the circumference, the circular outer plate 314 is rotatably connected to the container bottom 2, and the limiting matching portion is at least arranged on the circular outer plate 314.

[0159] The rotating connection part 33 is located at the end of the wrench 3, which is conducive to increasing the length of the force arm when rotating the wrench 3, thereby reducing the operating force applied when rotating the wrench 3, and further reducing the difficulty of disassembling and assembling the tool set 1. Specifically, the rotating connection part 33 includes an inner plate 313 with an opening in the circumferential direction and a circular outer plate 314, and the inner plate 313 and the circular outer plate 314 are parallel to each other to form a double-layer structure, which is conducive to improving the strength and reliability of the wrench 3. Among them, the inner plate 313 with an opening in the circumference forms a locking part with an opening in the circumference, so that the locking part encloses a locking groove 311, which cooperates with the locking protrusion 113 on the knife seat 11 to lock or unlock the knife seat 11, and the circular outer plate 314 is rotatably connected to the bottom 2 of the container to realize the connection function of the wrench 3 and the bottom 2 of the container, and the limiting matching part is at least arranged on the circular outer plate 314 (for example, it can also be arranged on the circular outer plate 314 and the inner plate 313 or other structures at the same time), so that the limiting part and the locking part keep rotating synchronously, so that when the wrench 3 rotates to the knife removal position and the knife locking position, the locking groove 311 cooperates with the locking protrusion 113, and at the same time, the limiting part also happens to be stopped and matched with the limiting matching part.

[0160] Embodiment 3

[0161] The difference from the second embodiment is that: on the basis of the second embodiment, further, the number of the locking protrusions 113 is two, and the two locking protrusions 113 are symmetrically arranged at 180° about the central axis of the knife seat 11, such as Figure 1 As shown, the number of locking grooves 311 is equal to the number of locking protrusions 113 and corresponds one to one; the wrench 3 is U-shaped, as shown in FIG. Figure 2 , Figure 5 and Figure 7 As shown, it includes two rotating arms 31 parallel to each other and a connecting arm 32 connecting the two rotating arms 31. One end of the two rotating arms 31 away from the connecting arm 32 is rotatably connected to the container bottom 2, and the two rotating arms 31 are respectively provided with a locking protrusion 113 or a locking groove 311.

[0162] There are two locking protrusions 113, and the two locking protrusions 113 are symmetrically arranged at 180° about the central axis of the tool holder 11 (i.e., the rotation axis 331 line of the tool 12). Accordingly, the number of locking grooves 311 is equal to the number of locking protrusions 113 and corresponds one to one, which is beneficial to the force balance between the tool holder 11 and the wrench 3, thereby improving the reliability of the product. Furthermore, the wrench 3 is U-shaped, including two rotating arms 31 and a connecting arm 32. The connecting arm 32 is located between the two rotating arms 31 and connects one end of the two rotating arms 31, while the other ends of the two rotating arms 31 are rotatably connected to the container bottom 2. Since the two rotating arms 31 are respectively provided with locking protrusions 113 or locking grooves, the two rotating arms 31 can be driven to rotate synchronously by directly applying force to the connecting arm 32, so that the two locking protrusions 113 cooperate with the two locking grooves, thereby further reducing the difficulty of disassembly and assembly of the knife group 1; at the same time, the U-shaped structure of the wrench 3 can also avoid other structures on the container bottom 2 (such as the lower part of the knife group 1) to prevent interference during rotation.

[0163] The rotating arm 31 may adopt a double-layer plate structure, wherein the end of the inner plate away from the connecting arm 32 forms the inner plate 313, and the end of the outer plate away from the connecting arm 32 forms the circular outer plate 314; or, the inner plate 313 and the circular outer plate 314 are bonded together to form an integrated structure, such as Fig.11 As shown, the limiting groove 315 can extend from the circular outer plate 314 to the inner plate 313, as shown in FIG. Fig.11 Of course, the connecting arm 32 can also be eliminated to form two wrenches 3 for separate control.

[0164] Furthermore, the connecting arm 32 extends in a direction deviating from the length direction of the rotating arm 31 to form a handle, and an obtuse angle is formed between the handle and the rotating arm 31, such as Figure 8 and Fig.11 As shown; the container bottom 2 is provided with a receiving space, when the wrench 3 is in the locking position, the wrench 3 is located in the receiving space, such as Figure 6 shown.

[0165] The connecting arm 32 extends in a direction deviating from the length direction of the rotating arm 31 to form a handle, which increases the contact area with the wrench 3 when rotating the wrench 3, which is beneficial to improving the user's operating feel. At the same time, an obtuse angle is formed between the handle and the rotating arm 31, that is, the angle α between the handle and the rotating arm 31 is an obtuse angle, such as Figure 8 and Fig.11As shown, it is beneficial to reduce the longitudinal dimension of the wrench 3 when it is placed obliquely relative to the container bottom 2, thereby reducing the longitudinal dimension of the container bottom 2; and the container bottom 2 is provided with a receiving space, when the wrench 3 locks the knife holder 11, the wrench 3 is located in the receiving space, preventing the wrench 3 from leaking out, improving the aesthetics of the product, and also improving the reliability of use, and when the wrench unlocks the knife holder, the handle is located outside the receiving space, which is convenient for the user to operate the wrench, such as Figure 8 , Fig.10 and Fig.15 shown.

[0166] Furthermore, the container bottom 2 is provided with a limiting step 23. When the wrench 3 is located at the knife removing position and the knife locking position, the handle is against the limiting step 23. Figure 5 and Figure 7 shown.

[0167] A limiting step 23 is provided at the bottom 2 of the container. When the wrench 3 is in the knife removing position or the knife locking position, the handle rests against the limiting step 23 to prevent the wrench 3 from further rotating, thereby further improving the reliability of the wrench 3.

[0168] Furthermore, the knife holder 11 includes a supporting portion 111 and an inserting portion 112 connected to the supporting portion 111. Figure 1 As shown, the support portion 111 is supported on the container bottom 2, and the insertion portion 112 passes through the mounting hole 24 and cooperates with the locking component.

[0169] The knife holder 11 includes a supporting portion 111 and an inserting portion 112. The supporting portion 111 is supported on the bottom 2 of the container to prevent the knife holder 11 from falling downwardly out of the bottom 2 of the container. Therefore, when the locking component unlocks the knife holder 11, the knife holder 11 will also stay firmly in the current position without the knife holder 11 falling instantly, thereby preventing the knife holder 11 from hitting the table or even injuring the user, thereby improving the user experience; the inserting portion 112 is inserted into the mounting hole 24 and cooperates with the locking component to realize the locking or unlocking function of the locking component on the knife holder 11.

[0170] The shape of the mounting hole 24 matches the shape of the inserting portion 112. Fig.13 As shown, a sealing member 6 may be provided between the insertion portion 112 and the mounting hole 24. Fig.15 As shown, to improve sealing performance.

[0171] like Figures 14 to 17 As shown, the mixing cup 4 of the food processor provided by the embodiment of the second aspect of the present invention comprises: a cup body 41 and a knife assembly installation structure as in any one of the embodiments of the first aspect. A knife 12 is arranged in the cup body 41; the container bottom 2 is connected to the lower end of the cup body 41, and the knife 12 is installed on the knife seat 11 of the knife assembly and is rotatably connected to the knife seat 11.

[0172] The blending cup 4 provided in the embodiment of the second aspect of the present invention comprises the blade assembly installation structure of any one of the embodiments of the first aspect, and thus has all the beneficial effects of any of the above embodiments, which will not be described in detail herein.

[0173] The cup body 41 may be open at both ends, and a sealing structure may be provided between the container bottom 2 and the lower end of the cup body 41 to ensure sealing performance. The container bottom 2 may also be integrally connected to the cup body 41; or Figures 14 to 17 As shown, the cup body 41 has a accommodating cavity, the container bottom 2 is located below the accommodating cavity, and a heating plate and other structures are provided between the container bottom 2 and the cup body 41. At this time, the container bottom 2 can be connected to the side wall of the cup body 41 through the side panel 42. From the appearance, the side panel 42 constitutes a part of the side wall of the stirring cup 4, the container bottom 2 is the bottom of the stirring cup 4, and the side panel 42 and the container bottom 2 can be an integrated structure or a split structure.

[0174] During specific assembly, the tool 12 can be first installed on the tool holder 11 through the tool shaft to form the tool set 1. Figure 1 As shown, the knife set 1 is then assembled onto the container bottom 2 equipped with a locking component.

[0175] like Fig.14 As shown, the food processor provided by the embodiment of the third aspect of the present invention comprises: a mixing cup 4 and a machine base 5 as in the embodiment of the second aspect, wherein the machine base 5 is located below the mixing cup 4 and is connected to the mixing cup 4.

[0176] The food processor provided in the embodiment of the third aspect of the present invention includes the stirring cup 4 provided in the embodiment of the second aspect, and thus includes all the beneficial effects of any of the above embodiments, which will not be described in detail here.

[0177] In any of the above embodiments, the food processor is a wall breaking machine, a food processor, a juicer or a blender.

[0178] Of course, it is not limited to the above products, and can also be other food processing machines, such as soy milk machines, etc.

[0179] The structure and working principle of the food processor provided in the present application are described below with reference to a specific example, and compared with the prior art.

[0180] At present, the knife set 1 of the pot or wall-breaking cup of the cooking machine on the market is fixed in a way that the knife set 1 passes through the bottom of the cup from the inside of the pot, and then a nut or a spiral structure similar to a nut is used to lock the knife set 1 that has passed through the bottom of the pot, which is inconvenient to disassemble and assemble. When removing the knife, after loosening the bottom locking nut, the knife holder 11 is easy to fall out and hit the table. In addition, the nut is screwed in and locked in one direction. When the stirring blade has the forward and reverse function, there is a risk of the nut loosening in one of the rotation directions.

[0181] To this end, the present application provides a novel food processor, which specifically includes the following structure: Figure 1 As shown, the knife seat 11 is provided with two protruding posts (ie, two locking protrusions 113); Figure 2 As shown, the knife wrench is fixed to the bottom shell (i.e., the bottom 2 of the container) by a hinge connection and can be rotated within the range of 0° to 90°. Figure 6 and Figure 8 As shown, the knife wrench has a half-open cylinder (i.e., inner plate 313) at the hinge, which is concentric with the hinge column. When the knife wrench is at the 90-degree position (i.e., the knife removal position), the opening faces upward, and the knife assembly 1 is installed from top to bottom. The protrusion of the knife assembly 1 enters the cylindrical surface through the opening of the cylindrical surface of the knife wrench. The size of the cylindrical surface opening (i.e., the notch of the locking groove 311) is slightly smaller than the size of the protrusion of the knife holder 11, and there is an elastic structure (i.e., elastic arm 312) on one side of the opening. After the knife holder 11 is installed, it is stuck in the cylindrical surface of the knife wrench.

[0182] like Figure 5 and Figure 6 As shown, the knife remover wrench is moved to the 0 degree position (i.e., the knife locking position), and the cylindrical surface of the knife remover wrench opens to the right, thereby locking the knife holder 11.

[0183] like Fig.11 As shown, there are two grooves (i.e., two limiting grooves 315) at the hinge of the knife wrench. When it is at the 90-degree position, the elastic structure (i.e., the limiting protrusion 21) on the base slides into one of the grooves to fix the knife wrench at the 90-degree position. Fig.10 As shown; when at the 0 degree position, the elastic structure on the base slides into another groove to fix the knife wrench at the 0 degree position, as shown in FIG. Fig. 9 shown.

[0184] Therefore, when removing the knife, you only need to turn the knife removal wrench from the 0 degree position to the 90 degree position, and then pull out the knife set 1 from the bowl, which is convenient and quick. Locking and removing the knife, using the wrench structure, saves effort and is quick. When removing the knife, release the locking device, and the knife holder 11 will remain in the pot to prevent the knife holder 11 from falling instantly. Whether the stirring knife head rotates forward or reverse, the knife holder 11 will not loosen.

[0185] In summary, the knife assembly installation structure provided by the present invention is provided with an installation hole and a locking component on the bottom wall of the container bottom, and the locking component serves as a disassembly and assembly tool. The knife assembly can be installed on or removed from the container bottom by operating the locking component, which not only avoids the time-consuming and labor-intensive manual operation in the prior art, but also does not require the use of other tools for operation, thereby significantly reducing the difficulty of disassembly and assembly of the knife assembly, and is conducive to the rapid disassembly and assembly of the knife assembly. At the same time, since the locking component is directly installed on the bottom of the container, it can reciprocate between the knife disassembly position and the knife locking position relative to the bottom of the container, so the locking component will not be separated from the bottom of the container during use, which can prevent the locking component from being lost or confused with other tools, thereby improving the reliability of the use of the locking component, and there is no need to re-assemble and position the locking component every time the knife assembly is disassembled, thereby improving the convenience of use of the locking component, making the disassembly and assembly of the knife assembly more labor-saving and convenient. In addition, the locking component is used to lock or unlock the tool holder, eliminating the locking nut in the prior art. For products with forward and reverse tool rotations, this can prevent the nut from loosening and causing the tool holder to loosen when the tool rotates in one direction, thereby improving the product's reliability.
