Technical Field

[0001] The present invention relates to the technical field of kitchen equipment, and more particularly to a food processing device. Background Art

[0002] In order to improve the convenience of food processing, various processing devices for processing food have appeared in existing kitchens, such as a cutting machine for cutting food into strips or shreds, and a grinder for grinding food.

[0003] Considering that if each processing device is equipped with a power base for providing power, it will not only greatly increase the storage pressure, but also increase the cost of use for consumers; therefore, a component-type food processing device has emerged, which includes: multiple functional modules (such as a cutting module for cutting food, a crushing module for crushing food, etc.), and a power base adapted to multiple functional modules, and the power base has a power output shaft for outputting power. When in use, any functional module is connected to the power output shaft of the power base in a transmission manner according to the food processing requirements, so that different types of food processing equipment can be formed.

[0004] However, the above-mentioned component-type food processing device cannot meet the demand for efficient processing of various food materials, and the processing effect on various food materials is often unsatisfactory. Summary of the invention

[0005] The purpose of the present invention is to address the deficiencies of the prior art and to provide a food processing device that can simultaneously cut and mash food materials to better meet the needs of efficient processing of a variety of food materials and optimize the cutting and mashing effects of food materials.

The side wall of the feed trough is provided with a discharge port. A knife cylinder assembly for cutting food is installed in the feed trough. The knife cylinder assembly is transmission-connected with: a cutting connection shaft that is driven to run by rotation; The first shaft is drivingly connected to the crushing connecting shaft so as to drive the crushing connecting shaft to rotate and transmit rotational power to the crushing connecting shaft; The second shaft is drivingly connected to the cutting connection shaft so as to drive the cutting connection shaft to rotate and transmit rotational power to the cutting connection shaft.

[0010] As a further preferred solution, one end of the clamping block passing through the installation groove is further formed with: a guiding inclined surface extending obliquely and used for pressing the hole wall of the docking part when the plug-in part is inserted into the docking part.

[0011] As a further preferred solution, the power base is also provided with: A slidable support rod; and an elastic member for applying elastic force to the support rod; Under the elastic force of the elastic member, the support rod presses against the insertion end of the plug-in part and applies a thrust force to the plug-in part to drive it to withdraw from the docking part.

[0028] The present invention is specifically described below with reference to the embodiments: Example: The food processing device is a device for processing food, which mainly includes functional modules set according to food processing requirements (such as a cutting module a for cutting food, a crushing module c for crushing food), and a power base b that provides power support for the functional modules.

[0029] The power base b mainly includes a base shell b1, and a power device b2 (such as a rotating motor) placed in the base shell b1 and used to provide rotational power; it has a power output shaft b2.1 that outputs the rotational power by rotating.

[0030] By connecting the functional module to the base shell b1, and making the corresponding functional structure for food processing in the functional module (such as the crushing component or the knife component mentioned below) transmission connected to the power output shaft b2.1, the power base b provides the functional module with power to drive the functional module to operate so as to perform food processing actions.

[0031] Due to the power output limitation of the power base b (i.e., it often only has one power output shaft b2.1), within a period of time, the power base b can often only be connected to one functional module and cannot be connected to multiple functional modules at the same time to process a variety of ingredients synchronously, resulting in its overall processing efficiency being low and unable to meet the efficient processing needs of a variety of ingredients.

[0032] Moreover, for the sake of simplicity of operation, the power output shaft b2.1 can often only rotate at one speed, while the requirements for the speed of the cutting module a, which requires low speed and high torque to continuously and stably cut or slice the food, and the high-speed grinding module c, which requires high speed to grind the food, are different. No matter which module is set to adapt to the power output shaft b2.1, the other module often cannot process the food well, resulting in unsatisfactory processing effects on a variety of food.

[0033] If, based on demand and according to conventional thinking, the number of power devices b2 is directly stacked in the power base b to achieve multi-position power output; on the one hand, the overall size of the power device b2 is large, which will increase the burden of transportation and storage; on the other hand, the overall cost of the power device b2 (such as a rotating motor) is high, and it is impossible to control and reduce the cost well, resulting in the product being unable to form better market competitiveness; moreover, multiple power devices b2 will also increase the difficulty of control.

[0034] Based on this, the present embodiment provides: a food processing device that can simultaneously cut and mash food ingredients to better meet the needs of efficient processing of various food ingredients and can optimize the cutting and mashing effects of food ingredients.

[0035] Specifically, the food processing device includes a power base b, a crushing module c, and a cutting module a.

[0036] Among them, for the power base b: As attached Figures 2 to 4 As shown, it includes a base housing b1, and a power device b2, a first shaft b3 and a second shaft b9 placed in the base housing b1. The power output shaft b2.1 is transmission-connected to the first shaft b3 and the second shaft b9, so that the first shaft b3 and the second shaft b9 can rotate synchronously with the power output shaft b2.1.

[0037] Specifically, the first shaft b3 is connected to the power output shaft b2.1 of the power device b2 through the first transmission structure to form an output shaft for outputting the rotational power of the power device b2. The second shaft b9 is connected to the power output shaft b2.1 of the power device b2 through the second transmission structure to form another output shaft for outputting the rotational power of the power device b2. The first transmission structure and the second transmission structure are commonly used gear transmission structures or belt transmission structures set according to transmission requirements.

[0038] The base shell b1 is respectively matched with the first shaft b3 and the second shaft b9 and is provided with: a first clearance hole b1.3 for connecting the first shaft b3 with the crushing connecting shaft c4; and a second clearance hole b1.2 for connecting the second shaft b9 with the cutting connecting shaft a5.

[0039] At the same time, if attached Figure 3 As shown, a protective shell b10 is provided in the base shell b1 to match the transmission structure, and the first transmission structure and the second transmission structure, as well as the power device b2, are all placed in the protective shell b10. One end of the first shaft member b3 for transmission connection with the crushing module c passes through the protective shell b10 and is inserted into the first clearance hole b1.3, and can also be rotatably connected to the base shell b1 by, for example, a bearing; one end of the second shaft member b9 for transmission connection with the functional module passes through the protective shell b10 and is inserted into the second clearance hole b1.2, and can also be rotatably connected to the base shell b1 by, for example, a bearing.

[0040] Among them, the crushing module c is a food processing module used to process food at high speed to crush the food, such as the module for crushing food in the existing commonly used meat grinder, or the crushing module for crushing food in the wall breaking machine.

[0041] In this embodiment, the crushing module c includes a crushing base c1, which is provided with a crushing groove c1.1 with an opening facing upward, and the crushing groove c1.1 is for placing food. At the same time, the crushing base c1 is rotatably connected with: a crushing shaft c3 with a vertical axis, which is a vertical axis extending in the vertical direction; a plurality of stirring blades c3.1 for crushing food are arranged on the outer periphery of the crushing shaft c3. The crushing shaft c3 and the stirring blades c3.1 together form: a crushing assembly for crushing food.

[0042] The crushing base c1 is also detachably fixed with a covering plate c2, for example, by a threaded structure, which covers the opening of the crushing trough c1.1; by removing the covering plate c2, the crushing trough c1.1 is open for materials to be placed in, and by installing the covering plate c2, the opening of the crushing trough c1.1 is covered to prevent the materials in the crushing trough c1.1 from splashing out.

[0043] The bottom of the crushing base c1 is rotatably connected with: a downwardly protruding crushing connecting shaft c4, the axis of which extends vertically, and the crushing connecting shaft c4 is connected to the crushing shaft c3 by a coupling, a gear or a plug-in transmission structure, so that: when the crushing connecting shaft c4 rotates, it can drive the crushing shaft c3 and the stirring blade c3.1 to rotate synchronously, thereby crushing the food in the crushing groove c1.1.

[0044] Among them, the cutting module a is a food processing module used to process food at a relatively low speed to slice or dice the food, such as a module with a knife for cutting food in an existing commonly used vegetable cutter or meat cutter.

[0045] In this embodiment, the cutting module a includes a cutting module housing a1 and a knife cylinder assembly a2 disposed in the cutting module housing a1.

[0046] Specifically, as attached Figure 4 As shown in the figure, a feed trough a1.1 with an upward opening is provided in the cutting module housing a1, and the opening at the upper end of the feed trough a1.1 forms a feed port a1.11 for placing food into the feed trough a1.1. At the same time, a side wall of the feed trough a1.1 (i.e., a side wall located at one side of the feed trough a1.1 in the horizontal direction) is provided with an outlet port a1.12 for the food in the feed trough a1.1 to flow out in the horizontal direction.

[0047] The feed trough a1.1 is also provided with a knife cylinder assembly a2, which is formed with a knife assembly for cutting food materials. The knife cylinder assembly a2 is matched with the discharge port a1.12 so that the cut food materials can flow out horizontally from the discharge port a1.12.

[0048] For example, Figure 2 As shown in , the knife barrel assembly a2 in this embodiment includes a cylindrical knife barrel body a2.1, the interior of the knife barrel body a2.1 is arranged as a cavity, and one end of the cavity is open to form a material storage groove a2.11. The knife barrel body a2.1 is placed horizontally in the feed groove a1.1, and the slot of the material storage groove a2.11 faces the discharge port a1.12 and is arranged opposite to the discharge port a1.12. At this time, the axis of the cylindrical knife barrel body a2.1 extends horizontally; the knife barrel body a2.1 is rotatably installed in the feed groove a1.1 and can rotate around the axis; at the same time, the side wall of the material storage groove a2.11 is provided with: a plurality of cutting holes a2.12 for connecting the feed port a1.11 with the material storage groove a2.11, and a cutting blade a2.2 is installed in each cutting hole a2.12, and one end of the cutting blade a2.2 extends to the outer surface of the knife barrel body a2.1.

[0049] During operation, the food is pressed into the feeding trough a1.1 from the feeding port a1.11 and fits against the outer wall of the knife barrel body a2.1; at the same time, the knife barrel body a2.1 is driven to rotate, and the rotating knife barrel body a2.1 can drive the cutting blade a2.2 to rotate synchronously to cut the food. The cut food falls into the feeding trough a2.11 from the cutting hole a2.12 and can flow out laterally from the discharging port a1.12.

[0050] The inner wall of the knife barrel body a2.1 is provided with an inclined surface to guide the food materials falling into the material placing groove a2.11 to flow toward the material discharging port a1.12.

[0051] It also includes a cutting connection shaft a5 that is rotatably connected to the cutting module housing a1 and is used to drive the knife barrel assembly a2 to operate. In this embodiment, the axis of the cutting connection shaft a5 is arranged horizontally, and it is a horizontal axis that extends in the horizontal direction. One end of the cutting connection shaft a5 is directly connected to the knife barrel body a2.1 (the cutting connection shaft a5 is fixed to the knife barrel body a2.1 in an irremovable manner by, for example, welding, or the cutting connection shaft a5 is detachably connected to the knife barrel body a2.1, for example, a structure in the knife barrel component of a vegetable cutting machine with a publication number of CN205343282U is adopted, so that the cutting connection shaft a5 is detachably buckled to the knife barrel body a2.1) or is transmission-connected to the knife barrel body a2.1, and the other end passes through a side wall of the cutting module housing a1 facing the power base b and is exposed outside the cutting module housing a1. For example, in this embodiment, a connecting shaft insertion hole a1.13 is provided on a side wall of the cutting module housing a1 facing the power base b, and the cutting connecting shaft a5 is rotatably inserted into the connecting shaft insertion hole a1.13, and the other end of the cutting connecting shaft a5 passes through the connecting shaft insertion hole a1.13 and is exposed outside the cutting module housing a1. By driving the cutting connecting shaft a5 to rotate, the knife barrel body a2.1 and the knife barrel assembly a2 can be driven to rotate, thereby achieving the cutting action of the food as described above.

[0052] When the food processing device is formed, the crushing module c is connected to the base shell b1 of the power base b, and the first shaft member b3 is transmission-connected to the crushing connecting shaft c4 so as to drive the crushing connecting shaft c4 to rotate and transmit rotational power to it; at the same time, the cutting module a is connected to the base shell b1 of the power base b, and the second shaft member b9 is transmission-connected to the cutting connecting shaft a5 so as to drive the cutting connecting shaft a5 to rotate and transmit rotational power to it.

[0053] At this time, the power device b2 drives the power output shaft b2.1 to rotate, which can drive the first shaft b3 and the second shaft b9 to rotate, and then drive the crushing connecting shaft c4 and the cutting connecting shaft a5 to rotate, so that the crushing module c and the cutting module a can process the food at the same time, so as to be able to perform the crushing and food cutting work synchronously to meet the needs of efficient processing of various food ingredients.

[0054] Furthermore, by setting the first transmission structure and the second transmission structure, when the power output shaft b2.1 drives the first shaft b3 and the second shaft b9 to rotate synchronously, the rotation speed of the first shaft b3 is configured to be higher than the rotation speed of the second shaft b9, so that under the limitation of the output rotational force of a power device, both the crushing module and the cutting module can have better food processing effects, thereby optimizing the overall user experience of the food processing device.

[0055] On the basis of the above scheme, the structural characteristics of the crushing module c and the cutting module a are taken into consideration, and the possibility of collision is reduced.

[0056] In this embodiment, the first shaft b3 is configured as a vertical shaft with its axis arranged vertically and extending in the vertical direction; the first clearance hole b1.3 is a through hole located on the upper end surface of the base shell b1 and opposite to the upper end of the first shaft b3. The second shaft b9 is configured as a horizontal shaft with its axis arranged horizontally and extending in the horizontal direction; the second clearance hole b1.2 is a through hole located on the side surface of the base shell b1 and opposite to one end of the second shaft b9.

[0057] As attached Figure 4 As shown, the power output shaft b2.1 is also a vertical axis with an axis arranged vertically and extending in the vertical direction; the first transmission structure is a coupling, the axis of the first shaft member b3 is colinear with the axis of the power output shaft b2.1, and the end of the first shaft member b3 is fixedly connected to the end of the power output shaft b2.1 through the coupling, so as to realize the transmission connection of the first shaft member b3 to the power device b2 through the first transmission structure.

[0058] The second transmission structure includes: the above-mentioned coupling, the first shaft b3, the worm gear b4, the transmission connecting shaft b5, and a plurality of gears.

[0059] Among them, a plurality of spirally extending helical teeth b3.1 are arranged on the outer surface of the first shaft b3, the transmission connecting shaft b5 is a horizontal axis and is placed on one side of the first shaft b3, and the transmission connecting shaft b5 is rotatably connected to the protective shell b10; a worm wheel b4 is fixedly connected to the transmission connecting shaft b5, and the outer teeth on the outer periphery of the worm wheel b4 are meshed and connected to the helical teeth b3.1 to form a worm gear transmission structure. In addition, a first connecting gear b6 is fixedly connected to one end of the transmission connecting shaft b5 away from the worm wheel b4, and at the same time, a second connecting gear b8 is fixedly connected to the second shaft b9, and the first connecting gear b6 and the second connecting gear b8 are meshed and driven by the third connecting gear b7. Then it is realized that when the power output shaft b2.1 drives the first shaft b3 to rotate to output the rotational power at one position, it can also synchronously drive the second shaft b9 to rotate to output the rotational power at another position. In this embodiment, the third connecting gear b7 is fixedly mounted on a shaft, and the shaft is rotatably connected to the protective shell b10 so that the third connecting gear b7 can rotate stably.

[0060] At this time, by increasing the diameter of the worm gear b4 and the number of teeth on its outer circumference, it can be achieved that when the power output shaft b2.1 drives the first shaft b3 and the second shaft b9 to rotate synchronously, the rotation speed of the first shaft b3 is configured to be higher than the rotation speed of the second shaft b9.

[0061] Furthermore, the crushing module c is placed on the upper end of the power base b in accordance with the first shaft b3, and the cutting module a is placed on one side of the power base b in accordance with the second shaft b9.

[0062] Specifically, in this embodiment, the end of the first shaft member b3 inserted in the first clearance hole b1.3 is provided with: a first spline groove b3.2 opening upward for plug-in transmission of the crushing connecting shaft c4; the end of the second shaft member b9 inserted in the second clearance hole b1.2 is provided with: a second spline groove b9.1 opening toward the cutting module a for plug-in transmission of the cutting connecting shaft a5.

[0063] The crushing module c is placed on the base housing b1, and the outer periphery of the lower end of the crushing connecting shaft c4 is provided with an external spline adapted to the first spline groove b3.2. When the crushing module c is placed on the base housing b1 from top to bottom, the crushing connecting shaft c4 with the external spline is inserted downward into the first spline groove b3.2, so that: the first shaft b3 is transmission-connected to the crushing connecting shaft c4, so as to drive the crushing connecting shaft c4 to rotate.

[0064] The cutting module a is placed on one side of the base housing b1, and the cutting connecting shaft a5 passes through the outer periphery of one end of the cutting module housing a1 and is provided with an external spline matching the second spline groove b9.1. When the cutting module a is laterally close to the base housing b1, the cutting connecting shaft a5 with the external spline is laterally inserted into the second spline groove b9.1, so that: the second shaft b9 is transmission-connected to the cutting connecting shaft a5, so as to drive the cutting connecting shaft a5 to rotate.

[0065] After the plug-in transmission is completed as described above, the crushing base c1 can also be detachably fixed to the base housing b1 by, for example, screws. The cutting and matching module a in this embodiment is detachably fixed to the base housing b1 by a plug-in structure.

[0066] Furthermore, the cutting module a has a plug-in portion a6 arranged toward the power base b, and the power base b has a docking portion b1.1 arranged toward the cutting module a; when the second shaft member b9 is detachably plugged and transmission connected to the cutting connection shaft a5 as described above, the plug-in portion a6 is synchronously and detachably plugged into the docking portion b1.1, so that: the cutting module a is detachably connected to the power base b.

[0067] On the one hand, if a groove structure is provided on the cutting module a, it will interfere with the internal food cutting space, which is not conducive to the smooth flow of food; on the other hand, in order to reduce weight, the inner wall of the existing cutting module shell a1 is generally provided close to the blade, resulting in a large space limitation inside the cutting module shell a1, and the groove structure cannot be formed; and if the groove is formed inward, in order to avoid interference with the existing blade, on the basis of providing the groove structure, the size of the cutting module shell a1 must be increased, which will greatly increase the size and weight of the cutting module shell a1, which not only puts higher requirements on the strength of the supporting structure, but also makes the food processing device as a whole more prone to tipping over.

[0068] Therefore, in this embodiment, the plug-in portion a6 is preferably: a plug-in column arranged on the side surface of the cutting module a facing the power base b and protruding toward the power base b; to be precise, the plug-in portion a6 is: a plug-in column arranged on the side surface of the cutting module shell a1 facing the power base b and protruding toward the power base b.

[0069] The docking part b1.1 is: a socket that matches the plug-in column and is arranged on the side surface of the power base b facing the cutting module a, and into which the plug-in column is inserted; in this embodiment, the docking part b1.1 is: a socket that is arranged on the side surface of the drive module housing b1 facing the cutting module a, and into which the plug-in column is inserted. The aperture of the socket matches the outer diameter of the plug-in column, and is preferably the same; but based on the requirements of smooth installation and the limitations of the production process, the aperture of the socket is generally slightly larger than the outer diameter of the plug-in column, provided that the plug-in support is met. At the same time, provided that the plug-in support and transmission are met, the slot diameter of the above-mentioned spline groove is generally also slightly larger than the outer diameter of the external spline.

[0070] The plug-in portion a6 is preferably a cylindrical protrusion with a circular cross section, so as to improve the convenience and smoothness of the plug-in assembly of the plug-in portion a6 and the docking portion b1.1 and reduce the possibility of positioning deviation.

[0071] At this time, the cutting module a moves laterally close to the power base b, so that the cutting connection shaft a5 with external splines is laterally inserted into the second spline groove b9.1, and the plug-in portion a6 is inserted into the docking portion b1.1, completing the installation of the cutting module a. In addition, the surface of the cutting module a can also be convexly formed with a boss arranged around the cutting connection shaft a5, and the second clearance hole b1.2 has a portion for the boss to be inserted; when inserted as described above, the boss is adapted to be inserted into the second clearance hole b1.2 to share the force on the cutting connection shaft a5 under the gravity of the cutting module a.

[0072] The cutting module a is moved laterally away from the power base b, so that the cutting connection shaft a5 with external splines is laterally disengaged from the second spline groove b9.1, and the plug-in part a6 is laterally disengaged from the docking part b1.1, completing the disassembly of the cutting module a.

[0073] On the basis of any of the above schemes, when there is a higher stability requirement to better avoid the cutting module a from falling off when it is subjected to a major impact, an anti-detachment structure acting on the plug-in part a6 can be additionally provided, which is configured to enable the plug-in part a6 to be in an active state that can be detached from the docking part b1.1, or in a locked state that cannot be detached from the docking part b1.1.

[0074] Specifically, as attached Figure 2 , Attachment Figure 5 To Attachment Figure 7 In the embodiment, the anti-drop structure is composed of the clamping hole b1.11, the clamping block a6.2, the elastic member a6.3 and the switch member b11.

[0075] Specifically, in this embodiment, the clamping hole b1.11 is a through hole provided on the hole wall of the docking portion b1.1, and is preferably provided on the hole wall of the docking portion b1.1 located above the plug-in portion a6. At the same time, the outer surface of the plug-in portion a6 is provided with an installation groove a6.1 that matches the clamping hole b1.11. Figure 7 When the plug-in part a6 is inserted into the docking part b1.1, the notch of the installation slot a6.1 is aligned with the clamping hole b1.11. The clamping block a6.2 is slidably installed in the installation slot a6.1, and the installation slot a6.1 is also provided with a limiting structure to prevent the clamping block a6.2 from sliding out of the installation slot a6.1.

[0076] In this embodiment, the limiting structure includes: a sleeve member a6.4 fixed in the installation groove a6.1 and sleeved on the outer periphery of the clamping block a6.2; and a flange portion a6.22 convexly arranged on the outer periphery of the clamping block a6.2. The inner wall of the sleeve member a6.4 is convexly formed with a clamping portion a6.41, and the clamping portion a6.41 is placed on the side of the flange portion a6.22 facing the notch of the installation groove a6.1 to prevent the flange portion a6.22 from sliding out of the installation groove a6.1, thereby preventing the clamping block a6.2 from sliding out of the installation groove a6.1. During installation, the clamping block a6.2 is first installed in the installation groove a6.1, and then the sleeve member a6.4 is embedded and fixed in the installation groove a6.1 to form the above-mentioned limiting structure.

[0077] The elastic member a6.3 is elastic and is installed in the installation groove a6.1. It elastically drives one end of the card block a6.2 to pass through the installation groove a6.1 and be clamped in the clamping hole b1.11. In this embodiment, the elastic member a6.3 is a spring, which is placed between the card block a6.2 and the groove wall of the installation groove a6.1 in a compressed state, so as to elastically drive one end of the card block a6.2 to pass through the installation groove a6.1 and be clamped in the clamping hole b1.11. The card block a6.2 has a portion protruding toward the groove bottom surface of the installation groove a6.1, and the protruding portion is inserted into the elastic member a6.3 of the spring structure, so that the elastic member a6.3 of the spring structure is sleeved on the outer periphery of the protruding portion, so as to improve the stability of the installation of the elastic member a6.3, and then the elastic member a6.3 can more stably drive the card block a6.2 to elastically slide.

[0078] At this time, the formation Figure 7 In the structure shown in C, the clamping block a6.2 is clamped in the clamping hole b1.11, and the plug-in portion a6 is in a locked state that cannot be separated from the docking portion b1.1.

[0079] At the same time, a switch member b11 for bearing external pressure is also provided, which can be slidably installed in the power base b and is configured to: when pressed, it can slide toward the docking part b1.1 to push the clamping block a6.2 out of the clamping hole b1.11.

[0080] Specifically, in this embodiment, as shown in the attached Figure 5 As shown, a slidable switch member b11 is slidably installed in the drive module housing b1. When the clamping hole b1.11 is a hole wall above the plug-in portion a6 and is a through hole vertically penetrating, the switch member b11 in this embodiment is preferably arranged above the clamping hole b1.11. One end of the switch member b11 is exposed on the outer surface of the power base b, for example, Figure 5 In the embodiment, the upper end of the switch element b11 can be slidably mounted on the top of the driving module housing b1 in a vertical direction; the other end of the switch element b11, for example, Figure 5 The lower end of the middle switch b11 is extended to form: a part placed outside the docking part b1.1 and opposite to the clamping hole b1.11, and the part has a pressing part b11.1 protruding toward the clamping hole b1.11 and close to the clamping block a6.2. The size of the pressing part b11.1 is adapted to the hole depth of the clamping hole b1.11 and the size of the clamping block a6.2 inserted into the clamping hole b1.11, and the slidable direction of the switch b11 in the driving module housing b1 is matched with the alignment direction between the pressing part b11.1 and the clamping hole b1.11, so that the pressing part b11.1 can be inserted and moved in the clamping hole b1.11 by driving the switch b11 to slide. So that: by pressing (referring to pressing the switch component b11 from the outside to drive the switch component b11 to move into the driving module housing b1) or not pressing the switch component b11, the plug-in part a6 can be in an active state that can be detached from the docking part b1.1, or in a locked state that cannot be detached from the docking part b1.1.

[0081] Specifically, when the cutting module a needs to be disassembled, the switch member b11 is pressed to drive the switch member b11 to move into the driving module housing b1, thereby driving the pressing portion b11.1 to be inserted into the clamping hole b1.11 from the outside, thereby pushing the clamping block a6.2 to be disengaged from the clamping hole b1.11 and slide into the mounting groove a6.1, and at the same time driving the elastic member a6.3 to elastically contract, the clamping block a6.2 is no longer clamped in the clamping hole b1.11, and the plug-in portion a6 is in an active state that can be disengaged from the docking portion b1.1. The cutting module a can be disassembled as described above.

[0082] Without pressing the switch element b11, under the elastic action of the elastic element a6.3, the switch can be opened as shown in the figure. Figure 7 As shown in FIG. C, the block a6.2 is stably mounted in the engaging hole b1.11, and the plug-in portion a6 is in a locked state that cannot be separated from the docking portion b1.1. The cutting module a is stably connected to the power base b for cutting and matching work.

[0083] In the above scheme, when the cutting module a needs to be connected to the power base b as described above, the plug-in part a6 with the clamping block a6.2 needs to be inserted into the docking part b1.1. The clamping block a6.2 needs to be manually pressed first to retract the clamping block a6.2 into the installation groove a6.1, which makes the installation more difficult.

[0084] Based on this, as attached Figure 6 As shown in , in this embodiment, at one end of the block a6.2 passing through the installation groove a6.1, there is formed a guide slope a6.21 which is extended and arranged obliquely, and when the plug-in part a6 is inserted into the docking part b1.1, the guide slope a6.21 will be connected with the hole wall at the end of the docking part b1.1, and the hole wall can press the block a6.2 and drive the block a6.2 to retract into the installation groove a6.1, so that the plug-in part a6 can be inserted into the docking part b1.1. When the plug-in part a6 is inserted until the block a6.2 is opposite to the clamping hole b1.11, the block a6.2 can be automatically clamped into the clamping hole b1.11 under the elastic action of the elastic member a6.3, forming an anti-slip structure.

[0085] In the above structure, based on the actual installation requirements and the limitation of the production process, after the plug-in part a6 and the docking part b1.1 are plugged in, there will be a gap between the plug-in part a6 and the docking part b1.1; similarly, after the second shaft b9 and the cutting connecting shaft a5 are plugged in, there will be a gap between the second shaft b9 and the cutting connecting shaft a5. Figure 8 As shown in Figure C, in order for the block a6.2 to be smoothly inserted into the engaging hole b1.11, the opening size of the engaging hole b1.11 is often slightly larger than the size of the block a6.2, resulting in a certain gap between the block a6.2 and the engaging hole b1.11 when the block a6.2 is engaged in the engaging hole b1.11. The above structural limitations make the cutting module a installed on the power base b prone to shaking.

[0086] In particular, when the power base b drives the cutting module a to cut the food, the shaking will intensify, which will not only generate excessive noise, but also have a bad impact on the transmission connection between the second shaft b9 and the cutting connection shaft a5, resulting in unstable transmission and uneven production of cut food, which in turn leads to a bad user experience.

[0087] Based on this, in this embodiment, the power base b can also be provided with: a support rod b13 placed on the side of the plug-in part a6 facing away from the cutting base a1 and slidable; and an elastic member b14 exerting elastic force on the support rod b13. Under the elastic force of the elastic member b14, the support rod b13 presses on the insertion end of the plug-in part a6, and exerts a thrust on the plug-in part a6 to drive it to withdraw from the docking part b1.1, so that: when the plug-in part a6 with the clamping block a6.2 is inserted into the docking part b1.1 as described above, the support rod b13 can push the clamping block a6.2 to more closely abut the side wall of the clamping hole b1.11, thereby improving the insertion stability. In this way, the cutting module a can be connected to the power base b in a more stable state, and when cutting food, it is not easy to shake, reduce the use noise, improve the transmission stability and food cutting effect, and optimize the use experience.

[0088] Specifically, in this embodiment, as shown in the attached Figure 6 , Attachment Figure 8 As shown in the figure, the docking portion b1.1 is a blind hole with an opening toward the cutting module a; a support rod mounting hole b1.12 is provided on the hole wall of the blind hole facing the cutting module a. The driving module housing b1 has: a support rod mounting groove b1.4 disposed on the side of the support rod mounting hole b1.12 facing away from the docking portion b1.1, and the notch is opposite to the support rod mounting hole b1.12. A support rod b13 that can slide laterally is installed in the support rod mounting groove b1.4, and a push spring b14 that is installed in a compressed state between the bottom wall of the support rod mounting groove b1.4 and the support rod b13 is also installed in the support rod mounting groove b1.4. Under the elastic force of the push spring b14, one end of the support rod b13 extends out of the notch of the support rod mounting groove b1.4, passes through the support rod mounting hole b1.12 and abuts against the plug-in part a6 inserted in the docking part b1.1, so as to apply a thrust to the plug-in part a6 to drive it to withdraw from the docking part b1.1.

[0089] Furthermore, due to the setting limitations of the above-mentioned structure, that is, one end of the cutting module a is connected to the power base b and is almost suspended in the upper area of ​​the cleaning tank c1.1; and there is a gap between the plug-in part a6 and the docking part b1.1, and a gap between the second shaft b9 and the cutting connection shaft a5, the cutting module a will be connected to one side of the power base b in a tilted state.

[0090] In particular, after the plug-in part a6 and the docking part b1.1 are plugged in as described above, the suspended part of the cutting module a tends to fall under the action of gravity, causing the insertion end of the plug-in part a6 to slightly warp, which in turn causes the central axis of the plug-in part a6 of the column structure (the central axis passing through the center of its cross-section and extending along the direction of its protrusion) and the central axis of the docking part b1.1 of the socket structure to often have a certain angle.

[0091] At the same time, there is often a certain angle between the central axis of the second shaft b9 and the central axis of the cutting connection shaft a5, which causes the rotational force of the second shaft b9 to be unable to be transmitted to the cutting connection shaft a5 quickly and stably, and is also prone to transmission wear problems.

[0092] Based on this, in this embodiment, the position of the support rod b13 is further limited so that the support rod b13 is set close to the lower end of the plug-in portion a6, so that the area where the support rod b13 applies thrust on the plug-in portion a6 is located below the central axis of the plug-in portion a6.

[0093] In this way, the support rod b13 not only pushes the block a6.2 to more closely contact the side wall of the clamping hole b1.11 as described above, thereby improving the insertion stability; when the block a6.2 is clamped in the clamping hole b1.11, it also applies a thrust to the plug-in part a6 to resist the upward tilt of its insertion end, so as to reduce the angle between the central axis of the plug-in part a6 and the central axis of the docking part b1.1. Furthermore, based on the setting of the synchronous plug-in structure (equipped with the output shaft b9 and the cutting connection shaft a5, which are synchronously inserted according to the insertion of the plug-in part a6 and the docking part b1.1), the angle between the central axis of the second shaft member b9 and the central axis of the cutting connection shaft a5 can also be reduced, so that the rotational force of the second shaft member b9 can be transmitted to the cutting connection shaft a5 more quickly and stably, and the transmission wear problem can also be reduced, so that the food can be cut steadily and evenly. At this time, the elastic force of the elastic member b14 is set according to the weight of the cutting module a in actual conditions to achieve the above effect.

[0094] In the above solution, since the support rod b13 and the elastic member b14 are provided to push the plug-in portion a6 with elastic force, the block a6.2 slidably installed in the installation groove a6.1 needs to bear a large pushing force. At this time, the upper end of the block a6.2 is tightly pressed against the side wall of the clamping hole b1.11 (for example, the side wall of the clamping hole b1.11). Figure 8 As shown in Figure C, the right side of the card block a6.2 is pressed against the right side wall of the card hole b1.11), and the lower end is pushed out of the pushing action of the docking portion b1.1, causing the card block a6.2 to easily tilt in the installation groove a6.1. Not only can it no longer provide stable support in the above process, so as to not be able to better solve the above transmission problem, but it can also not ensure that the card block a6.2 can slide smoothly in the installation groove a6.1, resulting in difficulty in disassembly and assembly of the cutting module a.

[0095] Therefore, the block a6.2 needs to be more tightly embedded in the installation groove a6.1, but this will greatly increase the difficulty of sliding the block a6.2, making it difficult to disassemble / assemble the cutting module a and resulting in a poor user experience.

[0096] Based on this, in order to balance the above problems, in this embodiment, the outer diameter of the flange a6.22 is set slightly smaller than the inner diameter of the sleeve a6.4, so that there is a gap between the flange a6.22 and the inner wall of the sleeve a6.4. At the same time, the outer periphery of the flange a6.22 is convexly formed with: a plurality of support portions a6.25 placed in the gap.

[0097] Several support parts a6.25 are distributed around the outer periphery of the flange part a6.22, and the convex surface of the support part a6.25 is a spherical surface, that is, the outer surface of the support part a6.25 protruding toward the inner wall of the sleeve part a6.4 is a spherical surface; the support part a6.25 is connected to the inner wall of the sleeve part a6.4 in a "point-to-face" form through the spherical surface.

[0098] Implementation: On the one hand, the block a6.2 is connected to the inner wall of the sleeve member a6.4 through multiple support parts a6.25 to ensure the installation stability of the block a6.2, which is not easy to be skewed in the installation groove a6.1, and can be stably pressed against the side wall of the clamping hole b1.11 during the above process; on the other hand, the support part a6.25 with a spherical surface structure is used to connect with the inner wall of the sleeve member a6.4, which can make the connection and fitting area between the block a6.2 and the inner wall of the sleeve member a6.4 very small while meeting the stable support requirements, so that the block a6.2 can slide relatively smoothly in the installation groove a6.1 according to the installation requirements. On the premise of ensuring the smooth sliding of the block a6.2, the more support parts a6.25 are set, the better.

[0099] Moreover, a positioning slot a6.42 opening toward the flange a6.22 may be provided on one side of the positioning portion a6.41 facing the flange a6.22. Meanwhile, a positioning pin a6.26 adapted to be inserted into the positioning slot a6.42 is formed protrudingly on one side of the flange a6.22 facing the positioning portion a6.41.

[0100] When the end of the block a6.2 passes through the installation groove a6.1 and can be installed in the clamping hole b1.11, the positioning pin a6.26 is adapted to be inserted into the positioning slot a6.42. The protruding height of the positioning pin a6.26 is generally 5 to 10 mm. Under the premise of not affecting the sliding smoothness of the block a6.2 as much as possible, the installation stability of the block a6.2 when the block a6.2 is clamped in the clamping hole b1.11 is further improved. Furthermore, when the elastic member b14 and the support rod b13 push the plug-in part a6 as described above, the block a6.2 pressed against the side wall of the clamping hole b1.11 can provide a more stable support point to better achieve the above effect.

[0101] For the elastic member a6.3 of the spring structure, as shown in the attached Figure 8As shown, the insertion end of the block a6.2 is provided with a spring positioning groove a6.23 with an opening toward the bottom surface of the mounting groove a6.1, the upper end of the elastic member a6.3 is positioned and installed in the spring positioning groove a6.23, and a positioning installation column a6.24 protruding toward the bottom surface of the mounting groove a6.1 is provided in the spring positioning groove a6.23, and the upper end portion of the elastic member a6.3 of the spring structure is sleeved on the outer periphery of the positioning installation column a6.24.

[0102] Furthermore, in any of the above solutions, in order to make the card block a6.2 more smoothly inserted into the card hole b1.11, in this embodiment, as shown in the attached Figure 6 As shown in FIG. 1 , a reset member b12 acting on the switch member b11 may also be provided in the power base b.

[0103] The reset element b12 in this embodiment is an elastic spring, one end of which is connected to the switch element b11 and the other end is connected to the drive module housing b1, and is configured to: when no external force is applied to the switch element b11, drive the switch element b11 to elastically reset to a state where it does not push the block a6.2. That is, drive the switch element b11 to reset to: Figure 7 As shown in C, the position of the switch member b11 when the clamping block a6.2 is clamped in the clamping hole b1.11.

[0104] For example, Figure 5 As shown in , the reset member b12 can be placed between the switch member b11 and the outer wall of the docking portion b1.1. When the switch member b11 is not pressed, the switch member b11 can be reset under the elastic action of the reset member b12, so that most of the top pressing portion b11.1 is separated from the clamping hole b1.11, leaving sufficient space for the clamping block a6.2. The specific position of the reset member b12 can be set according to actual needs.
