Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of food processing, in particular to a handheld food processor. BACKGROUND

[0002] In the field of food processing, food processors are widely used in household kitchens, catering industries and food processing factories due to their efficient food material processing capabilities. In particular, when processing ice-like food, food processors become indispensable equipment. To achieve sufficient whipping of ice-like food, existing food processors generally adopt a combined motion structure of "knife rotation + axial movement", that is, the knife is driven to rotate at high speed while slowly moving axially towards the bottom of the cup. The cutting force generated by rotation and the depth of stirring effect brought by axial movement gradually break and whip the blocky or granular ice-like food into fine ice slurry, ice mud or mixed food materials, so as to meet the diversified dietary needs of users for ice-cold drinks and frozen dishes. However, in actual application, the existing food processor has significant technical defects in the processing scheme for ice-like food, and the specific problems are as follows: Firstly, there is a lack of accurate perception and judgment mechanism for the freezing temperature of ice-like food, which cannot infer the hardness and whether it reaches the ideal whipping state corresponding to the taste threshold according to the actual freezing temperature of the food material. The freezing temperature of ice-like food directly determines its physical properties. For example, when the freezing temperature is too low (such as below -20℃), the crystallinity of water molecules inside the food material is high, and the overall hardness increases significantly. At this time, if the preset fixed whipping parameters (such as knife speed, movement speed, whipping time) are still used, the motor driving the knife needs to overcome much greater load resistance than in normal conditions. Long-term high-load operation will cause the motor winding to overheat and the insulation layer to age, and in severe cases, it may even cause the motor to burn out, shortening the service life of the equipment and increasing the maintenance cost of the user. Secondly, the existing technology cannot determine whether the food material has reached the frozen state through temperature, which easily leads to poor taste of the food material. Different types of ice-like food have different requirements for freezing temperature. For example, frozen fruits need to be maintained at -8℃ to -12℃, at which time the food material has a certain hardness and can be whipped into fine particles, and the water content and flavor of the fruit can be preserved. If the freezing temperature is too high (such as higher than -5℃), the food material will partially melt, and after whipping, it will easily form a sticky paste, losing the ice-cold taste. If the freezing temperature is too low (such as below -18℃), the food material is too hard, which will lead to insufficient whipping and the presence of unbroken hard blocks, affecting the eating experience. Since the existing food processor cannot detect the temperature of the food material, it cannot determine whether it is in the appropriate whipping temperature range, and can only rely on the user's subjective experience (such as touching the cup to perceive the temperature and observing the appearance of the food material) to determine whether to start whipping, which has low accuracy and is prone to errors, making it difficult to ensure the stability of the taste of the food material. Finally, the whipping decision of the existing food processor completely relies on the user's sensory judgment, the intelligent degree is low, the use experience is poor, and further improvement is needed.

[0005] As a preferred, the sealing cover is provided with a shaft hole, a transmission shaft is arranged in the shaft hole, and the transmission shaft is arranged to rotate relative to the shaft hole and move along the axial direction of the shaft hole; One end of the transmission shaft is in transmission connection with the main machine module, and the other end is in transmission connection with the cutter.

[0006] As a preferred, it further comprises an elastic reset element, one end of the elastic reset element abuts against the sealing cover, and the other end abuts against the main machine module; the elastic reset element is used to exert an upward moving force on the main machine module.

[0007] As a preferred, the main machine module comprises a mounting shell, a driver and a control circuit board; The mounting shell is arranged to move up and down relative to the connecting element; The driver and the control circuit board are fixedly installed on the installation housing; The control circuit board is connected with the driver and the infrared temperature measuring element; the control circuit board is configured to receive a temperature value transmitted by the infrared temperature measuring element, judge the temperature value, drive the driver to start when the temperature value is greater than a preset threshold A and less than a preset threshold B, and control the driver to remain in a standby state when the temperature value is less than the preset threshold A or greater than the preset threshold B.

[0008] Preferably, the installation housing and the connecting element are provided with upward and downward limiting structures that cooperate with each other; The upward limiting structure is used to constrain the maximum stroke of upward movement of the installation housing relative to the connecting element; The downward limiting structure is used to constrain the maximum stroke of downward movement of the installation housing relative to the connecting element.

[0009] Preferably, the connecting element is provided with a detection element for detecting whether the bowl is connected with the connecting element, and the detection element is connected with the control circuit board; The control circuit board controls the driver to drive the cutter to rotate to a preset position based on an electrical signal generated by the detection element.

[0010] Preferably, the connecting element and the bowl are connected by a buckle or a screw or a threaded structure.

[0011] Preferably, the driver is an electric motor.

[0012] Preferably, the sealing cover is inserted and fitted with the bowl in the up-down direction; the sealing cover is provided with a plurality of positioning portions, and the bowl is provided with a plurality of upper open positioning grooves corresponding to the positioning portions; the positioning portions are inserted into the positioning grooves from top to bottom.

[0013] Preferably, the connecting element is in a cylindrical structure with openings on both upper and lower sides.

[0014] Compared with the prior art, the present application innovatively integrates an infrared temperature measuring element and intelligent host control logic, effectively solves the core problems of existing food processors, such as easy damage of the motor, unstable taste of food, and low degree of intelligence, and the beneficial effects are embodied in the following aspects: First, significantly reduce the motor load pressure, prolong the service life of the equipment. In the scheme, the infrared temperature measuring element can accurately detect the real-time temperature of the food material in the bowl through the temperature measuring channel of the sealing cover, and transmit the temperature data to the host module. The host module only drives the cutter to rotate when the temperature value is in the appropriate interval of "greater than the preset threshold A and less than the preset threshold B"; when the temperature is lower than the preset threshold A (the food material is too hard), the cutter remains in standby state, avoiding the problem of excessive load of the motor in the prior art due to excessive freezing and hardness of the food material, reducing the risk of overheating of the motor winding, aging and burning of the insulation layer, reducing the user maintenance cost and prolonging the overall service life of the equipment. Second, accurately control the temperature interval of the food material to ensure the stability and consistency of the taste. For the temperature demand corresponding to the ideal taste of different ice-shaped food materials (such as frozen fruits, ice drink ice blocks and frozen milk slurry), reasonable threshold A and threshold B can be set (such as setting threshold A to-12℃ and threshold B to-8℃ for frozen fruits), so that the host module starts beating only when the food material is in this temperature interval. This avoids the problem of poor taste caused by excessive temperature (part of the food material melts and is sticky after beating) or low temperature (the food material is too hard and the beating is not sufficient with hard blocks) in the prior art, ensuring that the food material after each beating can achieve the ideal state of being delicate, ice-cold and flavor-keeping, and improving the stability and reliability of the eating experience. Third, realize the intelligentization of beating decision, and reduce the operation threshold of the user. The scheme realizes the intelligentization of beating decision through the linkage of the infrared temperature measuring element and the host module, completely replacing the cumbersome process of relying on the user's sense of touch and observation to judge the state of the food material in the prior art. The user does not need to have rich experience, and the equipment can automatically complete temperature detection, interval judgment and start-stop control.

[0015] Finally, the temperature measuring channel of the sealing cover provides a stable detection path for the infrared temperature measuring element, so that the infrared temperature measuring element can directly detect the temperature of the upper surface of the food, ensuring the accuracy of temperature detection, and preventing the food material from splashing during beating through the sealing effect of the sealing cover itself.

DETAILED DESCRIPTION

[0017] The application will be further described below in conjunction with the drawings and examples.

[0018] Referring to Figures 1-7 A handheld food processor, comprising a bowl 10, a drive module 20, a sealing cover 30, a cutter 40, and an infrared temperature measuring element 50; the bowl 10 is provided with an upper opening, and the drive module 20 is arranged above the bowl 10; the drive module 20 comprises a connecting element 210 and a main machine module 220; the connecting element 210 is detachably connected with the bowl 10; the main machine module 220 is arranged to move up and down relative to the connecting element 210; the sealing cover 30 is detachably connected to the upper side of the bowl 10; the cutter 40 is arranged in the bowl 10 below the sealing cover 30; the cutter 40 is in transmission connection with the main machine module 220 and can move up and down synchronously with the main machine module 220; the sealing cover 30 is provided with a temperature measuring channel 310 that penetrates up and down; the infrared temperature measuring element 50 is at least partially located in the temperature measuring channel 310 or is arranged directly above the temperature measuring channel 310; the infrared temperature measuring element 50 is used to detect the real-time temperature of the food material inside the bowl 10 and is in communication connection with the main machine module 220 to transmit the detected food temperature value in the bowl 10 to the main machine module 220; the main machine module 220 is configured to receive the temperature value transmitted by the infrared temperature measuring element 50, judge the temperature value, drive the cutter 40 to rotate when the temperature value is greater than a preset threshold A and less than a preset threshold B, and control the cutter 40 to remain in standby state when the temperature value is less than the preset threshold A or greater than the preset threshold B.

[0019] The handheld food processor is used for processing ice food, and the specific use principle is as follows: First, initial preparation of food material and equipment. The frozen food to be processed (such as frozen fruits, ice cubes, frozen milk slurry, etc.) is evenly loaded into the inside of the bowl 10, ensuring that the total amount of food material does not exceed the maximum capacity limit of the bowl 10, so as to avoid food material overflow during whipping; then, the sealing cover 30 is buckled on the upper opening of the bowl 10, and detachable connection is achieved through the adaptive structure (such as buckle, thread, etc.) between the sealing cover 30 and the bowl 10, so as to ensure good sealing between the sealing cover 30 and the bowl 10 and prevent food material splashing during subsequent whipping.

[0020] Secondly, the assembly of the driving module and the bowl is completed. The connecting element 210 of the driving module 20 is detachably connected with the bowl 10 (such as through snap butt joint, screw joint structure or threaded screwing, etc.), so that the driving module 20 is stably erected above the bowl 10; at this time, the main module 220 of the driving module 20 forms a transmission connection with the cutter 40 in the bowl 10, and the main module 220 can move up and down relative to the connecting element 210, thereby driving the cutter 40 to move up and down synchronously in the bowl 10, preparing for subsequent deep beating. Then, the infrared temperature measuring element starts to detect the temperature. After the equipment is assembled, the infrared temperature measuring element 50 starts to work through the pre-set up-and-down through temperature measuring channel 310 on the sealing cover 30; if the infrared temperature measuring element 50 is at least partially located in the temperature measuring channel 310, it can directly detect the temperature of the food material in the bowl 10 at close range; if the infrared temperature measuring element 50 is arranged directly above the temperature measuring channel 310, it can also accurately capture the infrared radiation signal of the food material through the temperature measuring channel 310, so as to obtain the actual temperature value of the food material in real time. Subsequently, the infrared temperature measuring element 50 transmits the detected temperature data to the main module 220 through a pre-set communication link (such as wire connection, wireless transmission, etc.), completes the collection and transmission of temperature information. Then, the main module makes intelligent judgment based on the temperature data and user operation. When the user manually presses the control switch 230 on the main module 220, the main module 220 immediately calls the latest temperature value transmitted by the infrared temperature measuring element 50, and compares it with the pre-set threshold A (lower temperature threshold, corresponding to the state of too hard food material) and threshold B (higher temperature threshold, corresponding to the state of too soft or partially melted food material): if the temperature value is greater than the pre-set threshold A and less than the pre-set threshold B, it means that the food material is in a suitable beating temperature range (moderate hardness, which can ensure that the taste is delicate after beating), so the main module 220 starts the driving program to control the cutter 40 to start rotating, and at the same time, the main module 220 is driven to move up and down relative to the connecting element 210 by external force, thereby driving the cutter 40 to move up and down synchronously while rotating, realizing efficient and deep beating of the food material; if the temperature value is less than the pre-set threshold A (the food material is too hard) or greater than the pre-set threshold B (the food material is too soft / melted), it is determined that the current state of the food material is not suitable for beating, so the main module 220 controls the cutter 40 to remain in standby state and does not start the beating action, avoiding high load operation of the motor or poor taste of the food material.

[0021] In the present application, the device state can also be fed back to the user by setting a prompting element on the host module 220. To improve the convenience of use, the device can be additionally configured with a buzzer, a display screen, etc. (electrically connected with the host module 220); when the host module 220 judges that the temperature value is less than the threshold A or greater than the threshold B, and controls the cutter 40 to remain in the standby state, the host module 220 will synchronously trigger the prompting element to work; if it is a buzzer, it will emit a preset frequency prompt sound (such as intermittent “drip-drip” sound) to remind the user that the food temperature is not suitable for whipping; if it is a display screen, it will directly display the current food temperature value and the text prompt of “temperature too low / high, not started yet”, and can further display the suitable temperature interval (such as “recommended temperature: threshold A~threshold B”) to guide the user to adjust the food temperature (such as placing the over-hard food for a while to warm up, or putting the over-soft food back to the refrigerator to freeze); if the temperature value is in the suitable interval, the cutter 40 is normally started to whip, and the prompting element can also emit a normal running prompt (such as a single sound prompt of the buzzer, the display screen displaying “normal whipping” and the real-time rotating speed, etc.) to let the user clearly master the running state of the device.

[0022] Referring to Figures 3 to 6 , the sealing cover 30 is provided with a shaft hole 300, a transmission shaft 200 is arranged in the shaft hole 300, the transmission shaft 200 rotates relative to the shaft hole 300 and is arranged to move along the axial direction thereof; one end of the transmission shaft 200 is in transmission connection with the host module 220, and the other end is in transmission connection with the cutter 40. The transmission shaft 200 is arranged in the shaft hole 300 of the sealing cover 30, on the one hand, it can rotate flexibly relative to the shaft hole 300, ensuring that the rotating power output by the host module 220 can be efficiently transmitted to the cutter 40, providing the cutter 40 with the rotating driving power required for whipping; on the other hand, the transmission shaft 200 can move freely along the axial direction of the shaft hole 300, when the host module 220 moves up and down relative to the connecting element 210, it can drive the cutter 40 to move up and down in the bowl 10 synchronously through the transmission shaft 200, realizing the composite whipping action of “cutter rotation + axial movement”, and ensuring the deep and uniform whipping of the ice-like food. At the same time, the shaft hole 300 plays a positioning and guiding role for the transmission shaft 200, avoiding the deviation and shaking of the transmission shaft 200 during rotation or movement, ensuring the stability of power transmission; and this structure realizes the transmission of power and movement while not damaging the sealing effect of the sealing cover 30 and the bowl 10, preventing food from splashing or soup from leaking during whipping, and taking into account the stability of device operation and the safety of use.

[0023] Further, a sealing ring is arranged between the shaft hole 300 and the transmission shaft 200, which can improve the sealing property of the two, preventing food from splashing to the outside from the gap between the two.

[0024] Referring to Figures 3 to 5Further comprising an elastic reset element 60, which is a spring or other existing elastic element, one end of the elastic reset element 60 abuts against the sealing cover 30, and the other end abuts against the host module 220; the elastic reset element 60 is used to exert an upward moving force on the host module 220. When the user drives the host module 220 to move downward relative to the connecting element 210 by external force (such as pressing the top of the host module 220), the host module 220 will generate a pressing force on the elastic reset element 60, causing the elastic reset element 60 to elastically deform and store elastic potential energy; when the external force driving the host module 220 downward is removed, the elastic reset element 60 will release the stored elastic potential energy and exert an upward moving force on the host module 220, assisting the host module 220 to quickly and smoothly recover to the initial position, without the need for the user to manually pull and reset, simplifying the operation process, and avoiding the problem that the host module 220 cannot automatically reset due to its own gravity or component friction jamming, thereby ensuring smooth implementation of the subsequent function of "moving the knife with the host module up and down to whip".

[0025] Referring to Figure 4 , the host module 220 comprises a mounting shell 221, a driver 222, and a control circuit board 223; the mounting shell 221 is arranged to move up and down relative to the connecting element 210; the driver 222 and the control circuit board 223 are both fixedly installed on the mounting shell 221; the control circuit board 223 is connected with 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, 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 state when the temperature value is less than the preset threshold A or greater than the preset threshold B.

[0026] The host module 220 specifically functions as follows: the mounting shell 221 provides a stable mounting carrier for the driver 222 and the control circuit board 223, and it can move up and down relative to the connecting element 210, driving the internal components and the knife 40 connected by transmission to move synchronously, thereby providing support for the axial whipping action of the knife 40; the driver 222 (such as a motor or a motor combined with a reduction gearbox for transmission) serves as a power source and can output rotary power under control, which is transmitted to the knife 40 through the transmission shaft 200, thereby providing driving force for the knife 40 to rotate and whip the food material.

[0027] The control circuit board 223 is a core control center, which is connected with the infrared temperature measuring element 50 and receives the temperature value of the food material in the bowl 10 in real time, judges the temperature value through a preset program, generates a start signal to drive the driver 222 to operate when the temperature is greater than a preset threshold A and less than a preset threshold B, and generates a standby signal to control the driver 222 to remain stationary when the temperature is less than the threshold A or greater than the threshold B, so as to avoid invalid beating or equipment overload. In addition, the control switch 230 is in touch connection with the control circuit board 223 to form a “human-computer interaction trigger end”, and the user sends an operation instruction to the control circuit board 223 by pressing the control switch 230. The control circuit board 223 only executes start or standby judgment based on the obtained temperature value after receiving the touch instruction, so as to ensure that the equipment is only operated when the user actively operates and the food material is suitable, and the operation safety and control accuracy are considered.

[0028] In the present application, the mounting shell 221 and the connecting element 210 are provided with upward and downward limiting structures matched with each other; the upward limiting structure is used to restrict the maximum stroke of the upward movement of the mounting shell 221 relative to the connecting element 210; and the downward limiting structure is used to restrict the maximum stroke of the downward movement of the mounting shell 221 relative to the connecting element 210. The mounting shell 221 and the connecting element 210 can be connected by a sliding block and a sliding rail to restrict the relative sliding arrangement. The upward and downward limiting structures can be provided with upper and lower limiting blocks for limiting the upward and downward movement of the mounting shell 221 on the connecting element 210. Alternatively, other limiting structures can be used, such as micro switches provided on the connecting element 210, and the mounting shell 221 is in touch with the micro switches to achieve limiting and sensing when the mounting shell 221 moves downward or upward to the maximum stroke relative to the connecting element 210.

[0029] In the present application, the connecting element 210 is provided with a detection element for detecting whether the bowl 10 is connected with the connecting element 210, and 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 with the control circuit board 223; the control circuit board 223 controls the driver 222 to drive the cutter 40 to rotate 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 specific angle, the blade of the cutter 40 is just below the infrared temperature measuring element 50, and in this case, the cutter 40 will affect the detection of the infrared temperature measuring element 50. However, the present embodiment can drive the cutter 40 to rotate after the bowl 10 is assembled with the connecting element 210, so as to change the position of the blade and prevent the blade from affecting the detection of the infrared temperature measuring element 50. In order to further ensure that the blade does not hinder the detection of the infrared temperature measuring element 50, a sensing cooperation element can be arranged on the cutter 40 or the transmission shaft 200, and a sensor cooperating with the sensing cooperation element can be arranged on the main machine module 220 to accurately control the hovering position of the cutter 40 after rotation. If the sensing cooperation element is a magnet and the sensor is a Hall sensor.

[0030] Referring to Figure 6 , the sealing cover 30 is inserted and matched with the bowl 10 in the up-down direction; the sealing cover 30 is provided with a plurality of positioning portions 320, and the bowl 10 is provided with a plurality of upper opening positioning grooves 110 corresponding to the positioning portions 320; the positioning portions 320 are inserted into the positioning grooves 110 from top to bottom.

[0031] Referring to 3 and Figure 4 , the connecting element 210 is in a cylindrical structure with openings on the upper and lower sides. The main machine module 220 moves up and down at least partially in the cylindrical connecting element 210.

[0032] Referring to Figure 7 , the connecting element 210 is provided with a mounting bracket 211, and the infrared temperature measuring element 50 is fixedly arranged on the mounting bracket 211. The infrared temperature measuring element 50 uses an existing infrared temperature measuring sensor.
