Description

Technical Field

[0001] This utility model relates to the field of food processing technology, and in particular to a temperature measuring module for a handheld food processor. Background Technology

[0002] In the food processing industry, the demand for refined processing of icy foods (such as frozen fruit chunks and frozen vegetable puree ingredients) is increasing. Micro puree machines, as a type of specialized food processing equipment, are widely used in home kitchens, small catering establishments, and small food processing workshops due to their ability to finely grind food and produce purees. To meet the needs of adjusting the position of food in different processing steps, various micro puree machine structures with platform movement and drive functions have emerged in the existing technology. For example, a micro puree machine disclosed in Chinese utility model patent document (publication number: CN216674577U) has a core structure including a shell, a movable platform, a position motor, and a drive motor. The platform can move flexibly between a first position and a second position within the shell. The position motor is installed in the shell and coupled to the platform, driving the platform to rotate. The drive motor is fixed to the platform and adjusts the position of the power shaft synchronously with the platform's movement, thus cooperating to complete the food processing operation. However, in actual processing scenarios involving icy foods, the aforementioned existing micro-purifiers and similar food processing equipment have significant technical defects: because icy foods require specific freezing treatment before processing, their processing effect is directly related to the food's own temperature state; if the food temperature is too low (e.g., below -15℃), the food hardness will increase significantly. When the drive motor drives the blades or grinding parts to process the food, the motor needs to withstand a load far exceeding the norm. Long-term operation will cause the motor coil to overheat, the bearings to wear more, and may even cause the motor to burn out; conversely, if the food is not frozen sufficiently (e.g., the temperature is above -5℃), the food will soften and clump in some areas, which will not only prevent the formation of a uniform and delicate puree, but may also cause the blades to jam, affecting processing efficiency and the taste of the finished product. The key problem is that existing micro puree machines and similar food processing equipment are not equipped with corresponding temperature measurement modules, making it impossible to detect the real-time temperature of icy food placed inside the equipment.

[0003] This forces users to rely solely on experience to judge the degree of freezing of food during actual operation, making it difficult to accurately grasp the actual temperature of the food and thus determine whether it is within the appropriate hardness range for processing. Either the food is too hard, causing excessive load on the motor and shortening the equipment's lifespan; or the food temperature is too high, resulting in poor processing and failing to meet users' requirements for the finished product's texture. Further improvements are needed. Utility Model Content

[0004] The present invention aims to solve at least one of the technical problems existing in the prior art. To this end, the present invention proposes a temperature measuring module for a handheld food processor.

[0005] A temperature measuring module for a handheld food processor designed for this purpose is characterized by comprising a bowl, a sealing cap, and an infrared temperature measuring element. The bowl has an opening on its upper side; The sealing cap is detachably connected to the upper side of the bowl; The sealing cover is provided with a temperature measuring channel that runs vertically through the top and bottom; the infrared temperature measuring element is at least partially located in the temperature measuring channel or the infrared temperature measuring element is located directly above the temperature measuring channel. The infrared temperature measuring element is used to detect the real-time temperature of the food inside the bowl.

[0006] Preferably, a knife is provided inside the bowl-shaped part below the sealing cover; The sealing cover is provided with a shaft hole, and a drive shaft connected to the cutting tool is inserted through the shaft hole. The drive shaft is rotatable relative to the shaft hole and is movable along its axial direction.

[0007] Preferably, the device also includes a handheld host, which includes a connecting element and a host module; the connecting element is detachably connected to the bowl; the host module is vertically movable relative to the connecting element. The cutting tool is connected to the main unit through a transmission and can move up and down synchronously with the main unit. The infrared temperature measuring element establishes a communication connection with the host module to transmit the detected food temperature value inside the bowl to the host module.

[0008] Preferably, the system also includes an elastic reset element, one end of which abuts against the sealing cover and the other end of which abuts against the host module; the elastic reset element is used to apply an upward moving force to the host module.

[0009] Preferably, the host module includes a mounting housing, a driver, and a control circuit board; The mounting housing is movable vertically relative to the connecting element; The driver and control circuit board are both fixedly mounted on the mounting housing; The control circuit board is connected to the driver and the infrared temperature measuring element.

[0010] Preferably, the control circuit board is connected to a buzzer for providing high and low temperature alerts.

[0011] Preferably, the control circuit board is connected to a display screen for displaying temperature values.

[0012] Preferably, the sealing cap is inserted into the bowl in the vertical direction; the sealing cap is provided with a plurality of positioning parts, and the bowl is provided with a plurality of positioning grooves with upper openings corresponding to the positioning parts; the positioning parts are inserted into the positioning grooves from top to bottom.

[0014] Preferably, the infrared temperature measuring element is fixedly mounted on the connecting element, and the connecting element is provided with a wiring harness for connecting the infrared temperature measuring element and the host module.

[0015] Compared with existing technologies, this invention achieves accurate real-time detection of food temperature through an infrared temperature measuring element. In this module, the bowl, as the food-bearing component, has an open structure that facilitates the insertion and removal of food. The sealing cap not only seals the bowl and prevents food from splashing during processing, but also provides a stable temperature measuring path for the infrared temperature measuring element through a vertically penetrating temperature measuring channel. Whether the infrared temperature measuring element is located inside or directly above the temperature measuring channel, it can directly target the food inside the bowl, accurately capturing the food's temperature signal and providing real-time feedback on the actual temperature of the food. This changes the current situation where existing equipment relies on user experience to judge food temperature. This temperature detection can be controlled by the control circuit board and the main module to drive the blade or keep it in standby mode; or it can be used with the display screen to directly display the temperature value. Users can use this information to determine whether the food's hardness is suitable for processing, avoiding excessive motor load due to overly hard food, extending equipment life, and ensuring the taste of the processed food.

Detailed Implementation

[0017] The present invention will be further described below with reference to the accompanying drawings and embodiments.

[0018] See Figures 1-7 A handheld food processor includes a bowl 10, a handheld main unit 20, a sealing cover 30, a knife 40, and an infrared temperature measuring element 50. The bowl 10 has an opening on its upper side, and the handheld main unit 20 is positioned above the bowl 10. The handheld main unit 20 includes a connecting element 210 and a main unit module 220. The connecting element 210 is detachably connected to the bowl 10. The main unit module 220 is vertically movable relative to the connecting element 210. The sealing cover 30 is detachably connected to the upper side of the bowl 10. The knife 40 is positioned inside the bowl 10 below the sealing cover 30. The knife 40 is drive-connected to the main unit module 220 and can move vertically synchronously with the main unit module 220. The sealing cover 30 has a vertical through-hole design. A temperature measurement channel 310 is provided; the infrared temperature measuring element 50 is at least partially located in the temperature measurement channel 310 or is positioned directly above the temperature measurement channel 310; the infrared temperature measuring element 50 is used to detect the real-time temperature of the food inside the bowl 10 and establishes a communication connection with the host module 220 to transmit the detected food temperature value inside the bowl 10 to the host module 220; the host module 220 is configured to: receive the temperature value transmitted by the infrared temperature measuring element 50, judge the temperature value, and drive the blade 40 to rotate when the temperature value is greater than a preset threshold A and less than a preset threshold B; when the temperature value is less than the preset threshold A or greater than the preset threshold B, control the blade 40 to remain in standby state.

[0019] This handheld food processor is designed for processing icy foods. Its operating principle is as follows: First, prepare the food and equipment. Evenly fill the bowl 10 with the frozen food to be processed (such as frozen fruit, ice cubes, frozen milk, etc.), ensuring that the total amount of food does not exceed the maximum capacity of the bowl 10 to avoid spillage during mixing. Then, fasten the sealing cap 30 to the upper opening of the bowl 10. The sealing cap 30 and the bowl 10 are connected in a detachable manner through the matching structure (such as snaps, threads, etc.) to ensure a good seal between the sealing cap 30 and the bowl 10 and prevent food from splashing during subsequent mixing.

[0020] Next, assemble the handheld host and the bowl. Connect the connecting element 210 of the handheld host 20 to the bowl 10 in a detachable manner (e.g., by snap-fit, screw-on structure, or threaded engagement) so that the handheld host 20 is stably mounted above the bowl 10. At this time, the host module 220 of the handheld host 20 forms a transmission connection with the cutter 40 inside the bowl 10, and the host module 220 can move up and down relative to the connecting element 210, thereby driving the cutter 40 to move up and down synchronously inside the bowl 10, preparing for subsequent deep mixing. Next, the infrared temperature measuring element is activated to detect the temperature. After the equipment is assembled, the infrared temperature measuring element 50 starts working through the preset vertical temperature measuring channel 310 on the sealing cover 30. If the infrared temperature measuring element 50 is at least partially located within the temperature measuring channel 310, it can directly and closely detect the temperature of the food inside the bowl 10. If the infrared temperature measuring element 50 is positioned directly above the temperature measuring channel 310, it can also accurately capture the infrared radiation signal of the food through the temperature measuring channel 310, thereby obtaining the actual temperature value of the food in real time. Subsequently, the infrared temperature measuring element 50 transmits the detected temperature data to the host module 220 through a preset communication link (such as wire connection, wireless transmission, etc.), completing the acquisition and transmission of temperature information. Then, the host module makes intelligent judgments based on temperature data and user operations. When the user manually presses the control switch 230 on the main unit module 220, the main unit module 220 immediately retrieves the latest temperature value transmitted by the infrared temperature measuring element 50 and compares it with the preset threshold A (lower temperature threshold, corresponding to food that is too hard) and threshold B (higher temperature threshold, corresponding to food that is too soft or partially melted). If the temperature value is greater than the preset threshold A and less than the preset threshold B, it means that the food is in a suitable temperature range for blending (moderate hardness, which can ensure a delicate texture after blending). The main unit module 220 then starts the driver program, controls the blade 40 to start rotating, and simultaneously drives the main unit module 220 to move up and down relative to the connecting element 210 through external force, causing the blade 40 to move up and down synchronously while rotating, so as to achieve efficient and deep blending of the food. If the temperature value is less than the preset threshold A (food that is too hard) or greater than the preset threshold B (food that is too soft / melted), it is determined that the current state of the food is not suitable for blending. The main unit module 220 controls the blade 40 to remain in standby mode and does not start the blending action to avoid high load operation of the motor or poor food texture.

[0021] In this invention, a prompting element can also be set on the host module 220 to provide feedback on the device status to the user. To enhance ease of use, the device can be additionally equipped with a buzzer, display screen, and other prompting elements (electrically connected to the main module 220). When the main module 220 determines that the temperature value is less than threshold A or greater than threshold B and controls the blade 40 to remain in standby mode, the main module 220 will simultaneously trigger the prompting elements to operate. If it is a buzzer, it will emit a preset frequency of prompting sounds (such as intermittent "beep" sounds) to remind the user that the food temperature is not suitable for blending. If it is a display screen, it will intuitively display the current food temperature value and text prompts such as "Temperature too low / too high, do not start for now," and can further display the suitable temperature range (such as "Recommended temperature: threshold A~threshold B") to guide the user to adjust the food temperature (such as letting hard food warm up for a while, or putting soft food back in the freezer). If the temperature value is within the suitable range and the blade 40 starts blending normally, the prompting elements can also emit normal operation prompts (such as a single buzzer sound, the display screen showing "Normal blending" and real-time speed, etc.), allowing the user to clearly understand the device's operating status.

[0022] See Figures 3 to 6 The sealing cover 30 is provided with a shaft hole 300, and a drive shaft 200 passes through the shaft hole 300. The drive shaft 200 rotates relative to the shaft hole 300 and moves along its axial direction. One end of the drive shaft 200 is connected to the main unit module 220, and the other end is connected to the cutter 40. The drive shaft 200 passes through the shaft hole 300 of the sealing cover 30. On the one hand, it can rotate flexibly relative to the shaft hole 300 to ensure that the rotational power output by the main unit module 220 can be efficiently transmitted to the cutter 40, providing the rotational driving force required for the cutter 40 to stir. On the other hand, the drive shaft 200 can move freely along the axial direction of the shaft hole 300. When the main unit module 220 moves up and down relative to the connecting element 210, it can synchronously drive the cutter 40 to move up and down within the bowl 10 through the drive shaft 200, realizing a compound stirring action of "cutter rotation + axial movement", ensuring deep and uniform stirring of icy food. Meanwhile, the shaft hole 300 plays a positioning and guiding role for the transmission shaft 200, preventing the transmission shaft 200 from shifting or shaking during rotation or movement, and ensuring stable power transmission. Moreover, while realizing the transmission of power and motion, this structure does not damage the sealing effect of the sealing cover 30 and the bowl 10, preventing food from splashing or soup from leaking during stirring, thus taking into account both the stability of equipment operation and the safety of use.

[0023] Furthermore, a sealing ring is provided between the bearing 300 and the drive shaft 200. The sealing ring can improve the sealing performance of both and prevent food from splashing out from the gap between them.

[0024] See Figures 3 to 5It also includes an elastic reset element 60, one end of which abuts against the sealing cover 30 and the other end against the main unit module 220. The elastic reset element 60 is used to apply an upward force to the main unit module 220. When the user drives the main unit module 220 to move downward relative to the connecting element 210 by external force (such as pressing the top of the main unit module 220), the main unit module 220 will exert a squeezing force on the elastic reset element 60, causing the elastic reset element 60 to undergo elastic deformation and store elastic potential energy. When the external force driving the main unit module 220 downward is removed, the elastic reset element 60 will release the stored elastic potential energy and apply an upward force to the main unit module 220, assisting the main unit module 220 to quickly and smoothly return to its initial position without the need for the user to manually pull it back, simplifying the operation process. At the same time, it avoids the problem that the main unit module 220 cannot reset itself due to its own weight or component friction, ensuring the smooth implementation of the subsequent "tool moving up and down with the main unit module to stir" function.

[0025] See Figure 4 The host module 220 includes a mounting housing 221, a driver 222, and a control circuit board 223. The mounting housing 221 is vertically movable relative to the connecting element 210. The driver 222 and the control circuit board 223 are both fixedly mounted on the mounting housing 221. The control circuit board 223 is connected to the driver 222 and the infrared temperature measuring element 50. The control circuit board 223 is configured to: receive the temperature value transmitted by the infrared temperature measuring element 50, judge the temperature value, and drive the driver 222 to start when the temperature value is greater than a preset threshold A and less than a preset threshold B; and control the driver 222 to remain in standby mode when the temperature value is less than the preset threshold A or greater than the preset threshold B.

[0026] The main unit module 220 has the following specific functions: the mounting housing 221 provides a stable mounting carrier for the driver 222 and the control circuit board 223, and at the same time, it can move up and down relative to the connecting element 210, driving the internal components and the blade 40 connected by transmission to move synchronously, providing support for the axial stirring action of the blade 40; the driver 222 (such as a motor or a motor and a gearbox combined for transmission) serves as a power source, and can output rotational power under control, which is transmitted to the blade 40 through the transmission shaft 200, providing driving force for the blade 40 to rotate and stir the food.

[0027] The control circuit board 223 is the core control hub. On the one hand, it is connected to the infrared temperature measuring element 50 to receive the temperature value of the food in the bowl 10 in real time. The temperature value is judged by a preset program. When the temperature is greater than the preset threshold A and less than the preset threshold B, a start signal is generated to drive the driver 222 to operate. When the temperature is less than the threshold A or greater than the threshold B, a standby signal is generated to control the driver 222 to remain stationary to avoid ineffective stirring or equipment overload. In addition, the control switch 230 establishes a touch connection with the control circuit board 223, forming a "human-machine interaction trigger terminal". The user sends an operation command to the control circuit board 223 by pressing the control switch 230. The control circuit board 223 only performs the start-up or standby judgment based on the acquired temperature value after receiving the touch command, ensuring that the equipment only operates when the user actively operates and the food is in a suitable state, thus taking into account both operational safety and control accuracy.

[0028] In this invention, the mounting housing 221 and the connecting element 210 are provided with mutually cooperating upward and downward limiting structures. The upward limiting structure is used to constrain the maximum upward movement of the mounting housing 221 relative to the connecting element 210; the downward limiting structure is used to constrain the maximum downward movement of the mounting housing 221 relative to the connecting element 210. The mounting housing 221 and the connecting element 210 can be connected by a slider and a slide rail to constrain the two relative sliding configurations. The upward and downward limiting structures can be achieved by providing upper and lower limit blocks above and below the connecting element 210, respectively, to limit the upward and downward movement of the mounting housing 221. Alternatively, other existing limiting structures can be used, such as providing microswitches above and below the connecting element 210. When the mounting housing 221 moves downward or upward relative to the connecting element 210 to its maximum stroke, the mounting housing 221 contacts the microswitch to achieve limiting and sensing.

[0029] In this invention, the connecting element 210 is equipped with a detection element for detecting whether the bowl 10 is connected to the connecting element 210. The detection element can be a micro switch; that is, when the bowl 10 is assembled with the connecting element 210, the bowl 10 presses the sensing end of the micro switch. The detection element is connected to the control circuit board 223; the control circuit board 223 controls the driver 222 to rotate the cutter 40 to a preset position based on the electrical signal generated by the detection element. The purpose of this embodiment is that, since the cutter 40 is located below the sealing cover 30, when the cutter 40 is at a certain angle, the blade of the cutter 40 may be directly below the infrared temperature measuring element 50. In this case, the cutter 40 may affect the detection of the infrared temperature measuring element 50. This embodiment can change the position of the blade by rotating the cutter 40 after the bowl 10 is assembled with the connecting element 210, thereby preventing the blade from affecting the detection of the infrared temperature measuring element 50. To further ensure that the blade does not obstruct the detection of the infrared temperature sensing element 50, a sensing element can be installed on the blade 40 or the drive shaft 200, and a sensor that works in conjunction with it can be installed on the main unit module 220 to precisely control the hovering position of the blade 40 after rotation. For example, a magnet can be used as the sensing element, and a Hall sensor can be used as the sensor.

[0030] See Figure 6 The sealing cover 30 is inserted into the bowl 10 in the vertical direction; the sealing cover 30 is provided with a plurality of positioning parts 320, and the bowl 10 is provided with a plurality of positioning grooves 110 with upper openings corresponding to the positioning parts 320; the positioning parts 320 are inserted into the positioning grooves 110 from top to bottom.

[0031] See 3 and Figure 4 The connecting element 210 has a cylindrical structure with openings on both the top and bottom sides. The main unit module 220 moves vertically within the cylindrical connecting element 210 in at least a portion.

[0032] In this invention, the infrared temperature measuring element 50 is fixedly mounted on the connecting element 210, and the connecting element 210 is provided with a wire harness for connecting the infrared temperature measuring element 50. The wire harness extends upward and connects to the control circuit board 223. For details, see [link to relevant documentation]. Figure 7 A mounting bracket 211 is provided on the connecting element 210, and the infrared temperature measuring element 50 is fixedly mounted on the mounting bracket 211. The infrared temperature measuring element 50 adopts an existing infrared temperature sensor.

[0033] In this invention, the control circuit board 223 is connected to a display screen for displaying temperature values. The display screen is an existing product and can be fixed to the outer wall of the connecting element 210 or the outer wall of the mounting housing 221, preferably mounted on the upper surface of the mounting housing 221. In this embodiment, after the user assembles the bowl 10 with the handheld host 20, the infrared temperature measuring element 50 detects the temperature of the food inside the bowl 10, and the control circuit board 223 ultimately displays the temperature value on the display screen. Temperature detection and display are existing technologies and will not be described in detail here.
