Description

Technical Field

[0001] This utility model belongs to the field of food processing, and in particular relates to a novel food processing machine. Background Technology

[0002] Existing vegetable choppers typically consist of a base and a mixing cup. A motor is housed within the base to provide power, while the mixing cup contains chopping components with blades. The motor drives the chopping components to cut and pulverize the ingredients in the mixing cup. Current vegetable choppers usually have only a single speed output, or two or more different speed switches to provide different speed levels. Users can either start the vegetable chopper directly or select different speed levels to meet different processing needs.

[0003] However, existing vegetable cutters operate at a single rotation speed during the cutting process. As the shredder rotates, it pushes the food against the wall of the mixing cup while simultaneously cutting it. On one hand, the continuous single rotation speed of the shredder creates a cutting equilibrium with the food, causing it to consistently cut the same area and reducing cutting efficiency. On the other hand, the shredder pushes the food to adhere to the wall of the mixing cup, and with the constant speed of the shredder, it is continuously compressed and firmly adhered to the cup. Ultimately, this results in food being cut into vastly different sizes after processing, leading to extremely poor processing quality.

[0004] Meanwhile, although existing food processors can be set to different speeds to meet the processing needs of different ingredients, the variety of ingredients that need to be cut is so wide that the existing speeds cannot meet the needs of all categories. As a result, users can only choose a single processing condition, which leads to poor processing results, affects user experience and satisfaction, and eventually leads to users abandoning the corresponding products. Summary of the Invention

[0005] The purpose of this utility model is to provide a new type of food processing machine that solves the technical problems of poor processing uniformity, limited adaptability to various food ingredients, and limited optional functions of existing food processing machines, which affect the user experience.

[0006] To solve the above-mentioned technical problems, this utility model provides a novel food processing machine, comprising: a housing; a mixing cup with an opening at the top for accommodating processed ingredients; a lid disposed at the opening of the mixing cup to cover it; a chopping component disposed within the mixing cup for crushing and cutting ingredients, the chopping component including a column and blades disposed on the column, a positioning post on the bottom wall of the mixing cup, the column being detachably mounted on the positioning post, and a transmission hole at the center of the lid for the column to pass through; a motor disposed within the housing; and a reduction gearbox including an input end and an output end coaxially arranged along the axial direction. The output end includes a gearbox connected below the motor, the motor shaft being poweredly connected to the input end, and the output end being poweredly connected to the upper end of the column; a safety switch located inside the housing and triggered when the housing is installed with the mixing cup and lid; and a controller configured to receive the safety switch activation signal to control the operation of the food processor; the controller is electrically connected to the motor, and the controller's operating period includes a first period and a second period, the controller controlling the voltage input to the motor, and the voltage values ​​input to the motor are different in the first and second periods.

[0007] This application solution includes a housing, a mixing cup, and a lid. A chopping component is housed within the mixing cup. Specifically, the bottom of the chopping component is positioned by a positioning post within the mixing cup, and its top passes through a transmission hole in the center of the lid and connects to a motor within the housing. The motor then outputs power through a reduction gearbox. Notably, the reduction gearbox has coaxial input and output ends, reducing the space occupied by the motor and gearbox and avoiding an increase in the overall size of the food processor. Furthermore, this application solution includes a safety switch and a controller. The safety switch is connected to the controller and can only be triggered when the housing, mixing cup, and lid are properly assembled. Only after the safety switch is triggered can the controller start the food processor, ensuring that the food processor can only be started after proper assembly, making it safer for the user. To better address the technical problems of insufficient and uneven food cutting in existing technologies, this application proposes a solution where the controller is electrically connected to the motor. The controller can control the input voltage of the motor. Specifically, during the working period of the food processor, the controller provides at least a first time period and a second time period, with the motor voltage differing between the first and second time periods. For example, the voltage in the first time period can be higher or lower than the voltage in the second time period. When the input voltage differs, the motor speed changes, which in turn causes a change in the speed of the shredder. Thus, during the operation of the food processor, a balance is not established between the shredder and the processed food. The processed food is constantly being shuffled and rearranged due to the continuous speed changes, thereby ensuring that all food is efficiently cut and shredded, thus improving the processing efficiency and effectiveness of the food processor.

[0008] As an alternative, the controller has multiple operating periods, with the voltage values ​​of the first period being the same or different, and the voltage values ​​of the second period being the same or different.

[0009] Different ingredients require different processing conditions. Multiple processing periods are set, each with at least a first period and a second period. Each first period can be further set with a different motor voltage, and each second period can also have a different motor voltage. This ensures that the food processor operates at different speeds throughout the entire processing process, thereby improving processing efficiency. Furthermore, by relying on different processing conditions, the ingredients are thoroughly disrupted, resulting in more uniform chopping and better performance.

[0010] As an alternative, the controller also includes a motor stop period located between two adjacent operating periods.

[0011] As an alternative, the controller also includes a motor stop period between the first and second time periods.

[0012] While setting different voltage values ​​at different times can prevent a dynamic balance from forming between the food and the chopping components, the food will still fluctuate when the chopping components are constantly in motion. Further setting a stop time, such as between two different processing periods or between the first and second periods within the same processing period, allows the chopping components to completely stop, causing the food in the mixing cup to stop and fall to the bottom. When restarted, it can be pushed to chop again, further improving chopping efficiency.

[0013] As an alternative, the blades are provided in at least two locations, arranged axially from top to bottom at different heights of the column.

[0014] As mentioned earlier, the chopper needs to completely chop the ingredients in the mixing cup, as users may place a certain amount of ingredients. Furthermore, the chopper's rotation also pushes the ingredients upwards. Therefore, the chopper is equipped with multiple blades, which are staggered along the axial direction in height. Blades at different heights can cut and pulverize ingredients at different heights. Simultaneously, driven by motors with different voltages and speeds, blades at different heights can push ingredients towards blades at other heights, further improving cutting efficiency and ensuring more uniform cutting.

[0015] As an alternative, the housing is also provided with a trigger link, one end of which abuts against the safety switch and the other end against the mixing cup or cup lid. The mixing cup or cup lid pushes the trigger link to trigger the safety switch.

[0016] To ensure better cutting of the shredded parts, the blades are typically quite sharp. If the food processor is started before the user has fully installed it, it could cause injury. Therefore, a safety switch is included. This safety switch is only activated when the lid is installed on the mixing cup, and the machine housing is further installed on the mixing cup and lid. This ensures the food processor can start normally and avoids the risk of starting with the shredded parts exposed.

[0017] As an alternative, the housing also includes a safety top cover that can trigger the safety switch, the safety top cover being axially movable to trigger the safety switch.

[0018] A safety top cover is further provided on the housing, which can also be pushed and triggered by the safety switch. Of course, the safety switch can be one, two, or more. For example, with one switch, it can be triggered simultaneously by the push of the safety top cover and the cup lid or mixing cup; with two switches, one is triggered by the safety top cover, and the other by the push of the cup lid or mixing cup; similarly, with multiple switches, they can be triggered by different functional components. Although a safety switch can typically be provided to ensure the safety of the food processor, it usually requires the user to continuously press the housing with a certain amount of pressure, which is inconvenient for the user. The safety cover is further designed so that users can start the food processor simply by pressing it, reducing user operations. In particular, the safety cover is designed to move axially to trigger the safety switch, aligning with the direction the user places and presses the machine casing, making operation smoother. Furthermore, the safety cover can be equipped with start and stop positions to control the start and stop of the food processor, making it even more convenient. Additionally, multiple safety covers can be added, each triggering a different safety switch and causing the controller to activate different control logic, achieving better pulverization and processing.

[0019] As an alternative, the main unit is also equipped with a safety linkage, one end of which abuts against the safety switch and the other end of which abuts against the safety top cover.

[0020] The housing needs to house components such as a motor, gearbox, controller, and safety switch, making it difficult for the safety switch to be directly connected to the safety cover for activation. A safety linkage is further provided, allowing the safety switch to be positioned differently depending on the other components. This safety linkage ensures that the safety cover can always trigger the safety switch.

[0021] As an alternative, the housing includes a shell and a bottom cover, the bottom cover having a recessed platform in its central area, and the gearbox being at least partially disposed within the recessed platform.

[0022] The food processing machine is equipped with a gearbox to match the speed of the motor and the workpiece. Typically, the motor operates at a relatively high speed, while the workpiece requires a lower speed during operation. Therefore, the gearbox reduces the motor speed to a suitable speed for the workpiece. The motor and gearbox are usually integrated and fixed together, with the motor shaft directly connected to the input shaft of the gearbox. This ensures efficient transmission between the motor and gearbox and prevents vibration and noise. Furthermore, a housing and bottom cover are provided, with a recessed platform in the center of the bottom cover for mounting the gearbox. This reduces the overall size of the main unit while ensuring the structural stability and reliability of the motor and gearbox.

[0023] As an alternative, the outer periphery of the sinking platform is provided with mounting columns, and the motor is fixed to the top of the mounting columns.

[0024] Furthermore, mounting columns are provided on the outer periphery of the sinking platform to simultaneously fix the motor to the top of the mounting columns. This allows the motor and the gearbox to be fixed inside the main unit at the same time, ensuring reliable synchronous installation of the motor and the gearbox. Attached Figure Description

[0031] To more clearly illustrate the overall concept of this application, a detailed description is provided below with reference to the accompanying drawings. It is to be understood that the specific embodiments described herein are merely illustrative of the relevant application and not intended to limit the application. Furthermore, it should be noted that, for ease of description, only the parts relevant to the application are shown in the accompanying drawings.

[0032] It should be noted that, unless otherwise specified, the embodiments and features described in this application can be combined with each other. The present application will now be described in detail with reference to the accompanying drawings and embodiments. The terminology used in this application is for the purpose of describing particular embodiments only and is not intended to be limiting of the application. The singular forms “a,” “the,” and “the” used in this application and the appended claims are also intended to include the plural forms unless the context clearly indicates otherwise. It should also be understood that the term “and / or” as used herein refers to and includes any or all possible combinations of one or more associated listed items.

[0033] like Figures 1-5 As shown, this utility model discloses a novel food processing machine, which includes a main unit 1, a lid 2, a chopping component 3, and a mixing cup 4. The mixing cup 4 has a top opening, through which the user places ingredients. Preferably, the mixing cup 4 has a large outer diameter and a large-diameter top opening, facilitating both the addition of materials and cleaning. The chopping component 3 is installed inside the mixing cup 4 to cut and pulverize the ingredients. The lid 2 covers the opening of the mixing cup 4, sealing the ingredients and the chopping component 3 inside. The main purpose of the lid 2 is to cover the ingredients and the processing component inside the mixing cup 4, preventing spillage and potential hazard from accidental contact with the processing component during operation. Although the main unit 1 can cover the top opening of the mixing cup 4, the main unit 1 contains a power component. When the main unit 1 is placed on the mixing cup 4, it usually drives the processing component to rotate for processing. However, when the main unit 1 is moved away, especially when it is suddenly displaced by external force during normal operation, the high-speed processing component will be directly exposed, posing a risk of splashing out. Therefore, a separate lid is provided to cover the mixing cup 4. Even if the main unit 1 is accidentally pushed away, there is no risk of the processing component flying out, making the food processor safer. The mixing cup 4, processing component, and lid 2 constitute a processing space for holding and processing the user's ingredients. The user only needs to assemble the ingredients and the corresponding processing component, and then install the main unit to start processing. When the main unit is not installed, the mixing cup 4, processing component, and lid have no power source and no live parts, ensuring high safety and no risk of use.

[0034] Preferred, such as Figure 1 , Figure 2As shown, the mixing cup 4 includes a cup body 41, with a positioning post 42 at the center of the bottom wall of the cup body 41 and baffles 43 on the inner sidewall of the cup body 41. The chopping component 3 includes a column 31 and blades disposed on the column 31. In this embodiment, multiple blades are provided, including an upper blade 32 and a lower blade 33. The upper blade 32 and the lower blade 33 are disposed at different heights along the axial direction of the column 31 from top to bottom, so that when the chopping component 3 is installed in the mixing cup 4, the upper blade 32 and the lower blade 33 can cut food at different heights. The upper blade 32 and the lower blade 33 each include two blades located on both sides of the column 31. It can be understood that the chopping component 3 may also have only a single blade on the column 31.

[0035] A transmission plug 34 is embedded in the bottom of the column 31. The transmission plug 34 has a positioning hole 35. When the shredder 3 is installed on the positioning post 42, the shredder 3 is sleeved on the positioning post 42 through the positioning hole 35, so that the shredder 3 rotates around the positioning post 42. A lower transmission head 36 is provided at the top of the column 31. A transmission hole 23 is provided in the center of the cup lid 2. The lower transmission head 36 passes through the transmission hole 23 and is poweredly connected to the main unit 1. It can be understood that the lower transmission head 36 can also be provided only at the transmission hole 23, and the transmission shaft of the main unit 1 passes through the transmission hole 23 to be poweredly connected to the lower transmission head 36.

[0036] like Figure 1 , Figure 3 , Figure 4 As shown, to process ingredients more efficiently, the main unit 1 includes a housing, a motor 5, a gearbox 51, and a controller 6. Preferably, the housing includes a shell 11 and a bottom cover 12, which interlock to form an internal installation space. The motor 5, gearbox 51, and control module are housed within this installation space and enclosed by the shell 11 and bottom cover 12, preventing direct contact with these components and ensuring greater safety for the main unit 1. The shell 11 and bottom cover 12 can also be designed to fit the specific requirements of the food processing machine. It is understood that the housing can also be designed with interlocking left and right sides, or it can include multiple interconnected structures to enclose the motor, gearbox, and control module, as long as safety and aesthetic requirements are met.

[0037] The main unit 1 comprises a shrinking section 101 and an assembly section 100 from top to bottom. The assembly section 100 is fastened to the top of the cup lid 2. To better fit with the cup lid 2 and cover the mixing cup 4, the assembly section 100 is sized to match the top opening of the cup lid 2 and the mixing cup 4. The shrinking section 101, extending upward from the top of the assembly section 100, can be set to a smaller size, so that the outer diameter of the shrinking section 101 is smaller than the outer diameter of the assembly section 100. In particular, the outer diameter of the shrinking section 101 is set to be suitable for one-handed grip and operation, so that the user can easily operate the food processor by operating the shrinking section. Preferably, the housing 11 forms an integral part of both the shrinking section and the assembly section, and the bottom cover 12 only closes the bottom opening of the housing 11. Directly forming the main parts of the shrinking section and the assembly section from the housing facilitates the structural design of the main unit and ensures the structural stability and reliability between the shrinking section and the assembly section.

[0038] The assembly section 100 and the shrinking section 101 respectively form installation spaces with different inner diameters within the main unit 1. Correspondingly, the inner diameter of the assembly section 100 is larger than that of the shrinking section 101. Typically, the motor 5 and the gearbox 51 are directly fixedly connected. Specifically, the motor shaft of the motor 5 extends into the gearbox 51 to directly form the input end of the gearbox 51, and the output end of the gearbox 51 ultimately forms the output end of the main unit 1. This ensures a stable and reliable connection between the motor 5 and the gearbox 51 and avoids noise generated when the transmission dimensions and structure between the motor 5 and the gearbox 51 are complex. Preferably, the motor 5 and the gearbox 51 are connected sequentially in the axial direction. For food processing machines that perform dough kneading and meat grinding functions, the outer diameter of the motor 5 usually does not need to be too large. On the one hand, a small-sized motor can meet the requirements; on the other hand, it is also necessary to consider the user's handheld operation, so it should not be too heavy. Based on this, the main part of the motor 5 can be located within the installation space formed by the shrinking section 101; even more specifically, the motor 5 can be completely housed within the shrinking section 101.

[0039] like Figure 1As shown, to ensure reliable installation of the main unit 1 on the cup lid 2, the top of the cup lid 2 is provided with a limiting recess 21, and the inner sidewall of the limiting recess 21 is provided with a limiting rib 22. The bottom of the main unit 1 is inserted into the limiting recess 21 and mutually limited by the limiting rib 22 to prevent the main unit 1 from sliding or rotating when installed on the cup lid 2. The bottom of the cup lid 2 is provided with a limiting ring 24 extending into the mixing cup 4. The limiting ring 24 is provided with a limiting groove 25. When the cup lid 2 is installed on the mixing cup 4, the limiting ring 24 extends into the mixing cup 4 and fits against the inner sidewall of the mixing cup 4. The limiting groove 25 cooperates with the limiting protrusion on the inner sidewall of the mixing cup 4 to prevent the cup lid 2 from rotating within the mixing cup 4.

[0040] like Figure 3 , Figure 4 As shown, to ensure that the output end of the gearbox 51 is reliably exposed at the bottom of the host 1, preferably, the bottom cover 12 is provided with a recessed platform 122 for mounting the gearbox 51. Simultaneously, a bottom cover hole 121 is provided at the center of the recessed platform 122. When the gearbox 51 is mounted on the recessed platform 122, the power output end of the gearbox 51 extends into the bottom cover hole 121. Alternatively, the power output end of the gearbox 51 can be located inside the bottom cover hole 121. When the host 1 is mounted on the mixing cup 4, the power connection end of the workpiece extends into the bottom cover hole 121 to connect with the power output end of the gearbox. To better install the motor 5 and gearbox 51, mounting posts 123 are provided on the outer periphery of the recessed platform 122, and mounting bosses 124 are provided on the top of the mounting posts 123. Preferably, the motor 5 is provided with a motor bracket that is fixedly connected to the mounting posts 123 and mounting bosses 124, so as to better fix the motor 5 and gearbox 51 to the bottom cover 12, and ultimately ensure the structural stability and reliability of the output of the motor 5 and gearbox 51. In this way, the gearbox is at least partially installed in the recessed platform, and the motor is fixed by the mounting posts surrounding the recessed platform and the gearbox. The fixing posts can also limit the outer periphery of the gearbox, so as to finally fix the motor and gearbox stably and reliably on the bottom cover 12 to achieve stable and reliable power output. Preferably, the outer periphery of the bottom cover 12 is also provided with locking posts 125. When the housing 11 and the bottom cover 12 are fastened together, fixing screws are provided in the locking posts 125 to fix the connection.

[0041] To ensure the safety of the food processing machine, especially the main unit, and to prevent accidental activation of the main unit 1 by the user, and to prevent the main unit 1 from rotating the processing component while mounted on the cup lid, preferably, the main unit also includes a safety switch 14 electrically connected to the control module. Alternatively, the safety switch 14 can be directly electrically connected to the motor 5. Thus, when the safety switch 14 is not activated, the motor 5 cannot operate normally. Preferably, as... Figure 3 As shown, a safety cover 13 is also provided on the top of the retractable section 101. When the user operates the retractable section 101 to use the main unit 1, the safety cover 13 can be pushed to move axially and trigger the safety switch 14, and the main unit 1 is powered on and works normally. As mentioned above, the space inside the assembly section 100 is larger, so it is preferable to set the safety switch inside the assembly section 100. In order to ensure that the safety cover 13 can trigger the safety switch 14 normally, a safety linkage 15 is also provided inside the main unit 1. One end of the safety linkage 15 abuts against the safety cover 13, and the other end abuts against the safety switch 14, so as to transmit the compressive force on the safety cover 13 to the safety switch 14 and trigger the safety switch 14.

[0042] like Figure 3 As shown, although the safety cover 13 and safety switch 14 ensure that the food processor can only be started when the user pushes the safety cover 13, this still poses a risk if the user does not install the main unit on the cup lid 2 and mixing cup 4. Preferably, a stop lever 17 is also provided on the inner side of the main unit 1. When the main unit 1 is installed on the cup lid 2, the cup lid 2 can push the stop lever 17 to trigger or push the safety switch 14. In this way, the main unit can only be started normally when its bottom is in contact with the cup lid and its top is pushed by the user, thereby ensuring that the food processor is safer and more reliable to use.

[0043] As mentioned earlier, if the motor in the main unit of the food processor operates at a single speed continuously during operation, a dynamic balance will be established between the shredder and the food. The shredder will continuously cut food in a specific area but will not effectively cut food in other areas, affecting processing efficiency and effectiveness. Based on the problems existing in the prior art, this application's solution includes a controller within the main unit. Specifically, the controller controls the motor's operation during a first period and a second period. The controller adjusts the input voltage of the motor to control its speed. By controlling the voltage values ​​at the first and second periods to be different, the speeds within the first and second periods will differ. Thus, during operation, the motor's speed continuously changes, leading to changes in the shredder's speed. This prevents a dynamic balance from being established between the shredder and the food, and the food is constantly disrupted by the speed changes during processing. This ensures that food in all areas is pushed to the shredder for cutting and pulverization, improving the processing efficiency and effectiveness of the food processor.

[0044] To better meet the needs of different processed ingredients and improve processing efficiency, the controller can be further configured with multiple working periods, each including a first period and a second period. In this simple control method, the voltage is the same for each first and second period, meaning the motor speed is the same in each first and second period, resulting in the motor operating in alternating high-low-high-low patterns throughout the working period. More effectively, the voltage is set to be different for each first and second period, or at least two or more different, thus allowing the motor speed to be in a erratic state for more efficient cutting and processing of the ingredients.

[0045] In order to better break the dynamic balance between the chopped pieces and the ingredients, the duration of the first time period and the second time period can be further controlled to be different; and multiple first time periods and second time periods with different durations can be set.

[0046] While setting different voltage values ​​at different times can prevent a dynamic balance from forming between the food and the chopping components, the food will still fluctuate when the chopping components are constantly in motion. Further setting a stop time, such as between two different processing periods or between the first and second periods within the same processing period, allows the chopping components to completely stop, causing the food in the mixing cup to stop and fall to the bottom. When restarted, it can be pushed to chop again, further improving chopping efficiency.

[0047] The following is an example of a control process for food processing to illustrate the control process of the food processing machine described in this application: After the food processing machine is started, in the first time period, at the first speed, the voltage of the motor is controlled to be 120V, and the motor works for 5 seconds; at the second speed, the voltage of the motor is controlled to be 220V, and the motor works for 20 seconds; the motor stops for 2 seconds; in the second time period, at the first speed, the voltage of the motor is controlled to be 180V, and the motor works for 5 seconds; at the second speed, the voltage of the motor is controlled to be 120V, and the motor works for 5 seconds; the motor stops for 2 seconds; in the third time period, at the first speed, the voltage of the motor is controlled to be 150V, and the motor works for 5 seconds; at the second speed, the voltage of the motor is controlled to be 220V, and the motor works for 10 seconds.

[0048] In the description of this application, it should be understood that the orientation or positional relationship indicated by directional terms such as "front, back, up, down, left, right", "horizontal, vertical, horizontal" and "top, bottom" is usually based on the orientation or positional relationship shown in the accompanying drawings, and is only for the convenience of describing this application and simplifying the description. Unless otherwise stated, these directional terms do not indicate or imply that the device or element referred to must have a specific orientation or be constructed and operated in a specific orientation, and therefore should not be construed as a limitation on the scope of protection of this application; the directional terms "inner" and "outer" refer to the inner and outer contours relative to the outline of each component itself.

[0049] For ease of description, spatial relative terms such as "above," "on top of," "on the upper surface of," "above," etc., are used herein to describe the spatial positional relationship of a device or feature as shown in the figures to other devices or features. It should be understood that spatial relative terms are intended to encompass different orientations in use or operation beyond the orientation of the device as described in the figures. For example, if a device in the figures were inverted, a device described as "above" or "on top of" other devices or structures would subsequently be positioned as "below" or "under" other devices or structures, but this does not imply that the actual device is inverted. Thus, the exemplary term "above" can include both "above" and "below." The device may also be positioned in other orientations, rotated 90 degrees, or in other orientations, and the spatial relative descriptions used herein will be interpreted accordingly.

[0050] Furthermore, it should be noted that the use of terms such as "first" and "second" to define components is merely for the purpose of distinguishing the corresponding components. Unless otherwise stated, the above terms have no special definition and therefore should not be construed as limiting the scope of protection of this application.

[0051] The above description is merely a preferred embodiment of this application and an explanation of the technical principles employed. Those skilled in the art should understand that the scope of this application is not limited to technical solutions formed by specific combinations of the above-described technical features, but should also cover other technical solutions formed by arbitrary combinations of the above-described technical features or equivalent features without departing from the application's concept. For example, technical solutions formed by substituting the above features with (but not limited to) technical features with similar functions disclosed in this application will not be listed here.
