Description

Technical Field

[0001] This utility model relates to the field of food processor technology, and in particular discloses an intelligent food processor with digital display function. Background Technology

[0002] As people's living standards continue to improve, many different types of food processors have appeared on the market. However, existing smart food processors generally suffer from problems such as unintuitive human-computer interaction interfaces, insufficient structural sealing, lack of safety protection, and weak intelligent monitoring functions. Traditional devices mostly use independent displays or mechanical control panels, which have drawbacks such as limited display information, many hard-to-clean areas, and poor waterproof performance. Utility Model Content

[0003] In order to overcome the shortcomings and deficiencies of the existing technology, the purpose of this utility model is to provide an intelligent food processor with digital display function.

[0004] To achieve the above objectives, this utility model provides an intelligent food processor with a digital display function, comprising a main unit and a food processing container used in conjunction with the main unit; the main unit includes a housing, a drive unit, a display component, and a control component, both of which are electrically connected to the control component; the drive unit is installed inside the housing; and the display component is disposed on the side wall or top wall of the housing, and is used to display the operating parameters of the drive unit.

[0005] The housing component includes an outer shell and an inner shell installed inside the outer shell. A drive unit is installed inside the inner shell. The inner shell has an installation window. The outer shell has a display window that communicates with the installation window of the inner shell. The display component is installed between the installation window and the display window. The display panel of the display component is flush with the outer surface of the outer shell.

[0006] The smart food processor features a double-layer shell structure design, with the drive components built into the inner shell and precise control achieved through control components. Combined with an embedded display component flush with the outer shell, this effectively improves the integration and ease of operation of the device. The alignment of the windows in the inner and outer shells enhances the stability and waterproof performance of the display module. Meanwhile, the flat outer surface design balances aesthetics and ease of cleaning. Users can intuitively monitor the working status and adjust parameters through the digital display screen, achieving a dual optimization of functionality and user experience.

[0007] The control components include a main circuit board installed inside the housing, a control module located above the main unit and movable vertically, and a food processor container housing a detachable and rotatable working mechanism. The control module is electrically connected to the main circuit board and is used to control the food processor by generating control commands. The main circuit board converts the control commands into drive commands and transmits them to the drive unit to drive the working mechanism inside the food processor container to rotate. At the same time, the main circuit board transmits the control commands to the display component, which displays the working status or setting parameters of the food processor in real time according to the received control commands.

[0008] The control components adopt a split design, with the upper control module receiving user commands directly and the lower circuit board efficiently converting signals and synchronously driving the stirring system and display interface, forming a closed-loop control of "operation-processing-execution-feedback". This ensures the real-time adjustment of parameters and the accuracy of stirring actions, while also intuitively presenting the working status and set parameters through a digital display screen, significantly improving human-machine interaction efficiency and equipment durability, and achieving a triple optimization of functional reliability, ease of operation and design aesthetics.

[0009] The display component has a sealing structure on its side, which abuts against the frame of the mounting window and the display window.

[0010] The sealing structure on the side of the display component abuts against the frame of the mounting window and the display window, which can effectively prevent dust, moisture and other substances from entering the main unit, avoid damage to the display component and other electronic components, and improve the protection performance and service life of the food processor.

[0011] The cooking container includes a mixing container, a mixing cover covering the mixing container, and a mixing blade rotatably mounted on the mixing container and / or the mixing cover. The mixing cover has a groove for accommodating a driving component, and a through hole is provided in the middle of the groove. The mixing blade includes a shaft component and a blade body mounted on the shaft component. The top of the shaft component has a transmission part connected to the driving component. The transmission part protrudes from the through hole in the middle of the groove of the mixing cover and is connected to the output end of the driving component.

[0012] The transmission part of the mixing blade protrudes from the through hole in the center of the mixing cover and connects to the output end of the drive unit. This connection method ensures that the drive unit can stably transmit power to the mixing blade, enabling the mixing blade to work efficiently and stably, thus improving the mixing effect. The mixing cover has a groove for accommodating the drive unit, making the entire food processing container structure more compact, reducing the space occupied by the food processor, and also facilitating the connection and installation of the drive unit and the mixing blade.

[0013] The bottom surface of the groove of the stirring cover is provided with a first annular protrusion, and the inner side of the first annular protrusion is provided with multiple sets of limiting protrusions. The driving component also includes a bottom shell that is installed in conjunction with the housing component. The bottom surface of the outer side of the bottom shell is provided with a second annular protrusion and a third annular protrusion disposed in the second annular protrusion. The second annular protrusion and the third annular protrusion together form an annular channel. The first annular protrusion is accommodated in the annular channel. Multiple sets of limiting notches are evenly distributed circumferentially on the third annular protrusion. The limiting protrusions of the first annular protrusion and the limiting notches of the third annular protrusion form a snap-fit ​​engagement.

[0014] The annular channel formed by the first annular protrusion on the bottom surface of the stirring cover groove and the second and third annular protrusions on the bottom shell of the drive component, as well as the locking protrusion of the first annular protrusion and the locking notch of the third annular protrusion, can accurately position the relative position of the stirring cover and the drive component, preventing the stirring cover from shaking or shifting during the stirring process, and ensuring the stability and safety of the stirring process.

[0015] The cutter body includes a bushing and multiple sets of blades disposed on the bushing. The bushing has a shaft hole and is fitted onto the shaft body through the shaft hole. The multiple sets of blades are disposed on the bushing at equal radial intervals around the central axis of the bushing.

[0016] The blades are arranged radially at equal intervals on the bushing and spaced apart from each other along the central axis of the bushing. This arrangement allows the mixing blades to cover a larger mixing area when rotating, improving the uniformity and efficiency of mixing and enabling the ingredients to be mixed to the desired state more effectively.

[0017] Each blade is equipped with a protective sleeve. The blade is crescent-shaped, and the protective sleeve is placed on the outside of the blade. One end of the protective sleeve is used to abut against the bushing.

[0018] Each blade is equipped with a protective sleeve, which protects the blade when the food processor is not in use, preventing damage to the blade and also preventing users from accidentally touching the blade and getting injured during operation, thus improving the safety of using the food processor.

[0019] The bottom of the mixing container is also provided with an anti-slip base, and the inner side of the anti-slip base is provided with an outward convex ring, which abuts against the side of the mixing container.

[0020] The non-slip base at the bottom of the mixing container and the inner convex ring abut against the side of the mixing container, increasing the friction between the mixing container and the countertop, preventing the mixing container from sliding or shaking during mixing, and ensuring the stability of the food processor.

[0021] The anti-slip base has a built-in piezoelectric vibration module and temperature sensor. When the temperature at the bottom of the stirring container exceeds the preset value or a horizontal deviation occurs, the adaptive balance compensation is activated through the main circuit board. At the same time, the display window flashes a warning icon and emits a frequency conversion buzzer prompt.

[0022] The built-in piezoelectric vibration module and temperature sensor on the sliding base can monitor the temperature and level of the bottom of the mixing container in real time. When the temperature exceeds the preset value or a level deviation occurs, adaptive balance compensation is activated, and a warning icon flashes in the display window and a variable frequency buzzer sounds to promptly remind the user to take appropriate measures to avoid safety accidents caused by excessive temperature or container deviation, thus improving the safety and reliability of the blender.

[0023] The stirring cover has a handle on its side, and the stirring container has a handle that works with the handle. The inner side of the handle has an arc-shaped guide rib that interlocks with the limiting groove of the container handle. A Hall sensor is embedded inside the container handle, and a magnet array is installed inside the handle. The magnet array inside the handle and the Hall sensor constitute a non-contact angle detection module. When it is detected that the handle and the handle are not fully closed, the control component prevents the drive component from starting.

[0024] The magnet array inside the handle and the Hall sensor inside the container handle form a non-contact angle detection module. When the handle is not fully closed, the control component prevents the drive from starting, thus preventing the drive from starting when the mixing lid is not closed, avoiding food splashing or injury to the user, and further improving the safety of the food processor.

[0025] The beneficial effects of this utility model are as follows: This utility model integrates the drive unit within the inner shell through a double-layer shell structure, coupled with an embedded display component flush with the outer shell, improving equipment integration while achieving waterproof and dustproof performance. The separate control components form a closed-loop system of "operation-processing-execution-feedback," ensuring real-time parameter adjustment and precise stirring action. The cooking container employs a direct-drive transmission unit and a multi-set staggered blade layout, combined with a limiting snap-fit ​​structure to ensure operational stability. A protective sleeve, anti-slip base, and temperature-sensing balance compensation system provide multiple layers of safety protection, while a non-contact angle detection module prevents the risk of accidental start-up. The overall design achieves synergistic optimization in terms of structural compactness, ease of operation, stirring efficiency, and safety, significantly improving user experience and equipment reliability.
