Description

TECHNICAL FIELD

[0001] The application belongs to the technical field of air fryers, and particularly relates to an air fryer with automatic lifting and pot body recognition functions. BACKGROUND

[0002] As a kind of kitchen appliance that cooks food by hot air circulation, air fryers are increasingly popular due to their convenience, low oil and healthy characteristics. Most of the air fryers currently on the market adopt a structure design of fixed capacity pot body and heating head in one or fixed connection, and the cooking capacity of which is not adjustable. When users need to cook a small amount of food, using a large capacity pot body not only wastes space but also affects the efficiency of hot air circulation, which may cause uneven heating of food. When cooking more food, the capacity of the pot body is limited. To solve this problem, some designs on the market allow the replacement of the pot body, but usually require users to manually remove the entire heating head and place it on the countertop or other places to replace the pot body of different heights. This operation process has obvious defects: first, the removed head is easy to be contaminated by kitchen oil and dust if not properly placed, which poses a health risk, and its heating components and internal structure may be affected in performance or safety due to contact with water vapor or foreign matter; second, the separated and placed head occupies countertop space and poses a risk of accidental falling and damage or loss of parts; third, the manual alignment and reinstallation process is cumbersome and the user experience is poor. Therefore, there is a lack of an air fryer structure in the prior art that can conveniently, hygienically and reliably adapt to different capacity pot bodies without the need to completely separate and store the head. SUMMARY

[0003] (I) Invention purpose In order to overcome the above shortcomings, the purpose of the present application is to provide an air fryer with automatic lifting and pot body recognition functions to solve the technical problems of poor flexibility, cumbersome operation and health and safety hazards caused by the fixed cooking capacity and the inability to conveniently and hygienically adapt to different size pot bodies of the existing air fryers.

[0004] (II) Technical solutions To achieve the above purpose, the technical solutions provided by the present application are as follows: The application discloses an air fryer with automatic lifting and pot body recognition function, which comprises a base, a guide rail assembly vertically arranged on one side of the base, a sliding seat in sliding cooperation with the guide rail assembly, a heatable machine head connected with the sliding seat, an elastic reset member, one end of which is connected with the upper end of the guide rail assembly and the other end of which is connected with the sliding seat, a locking assembly movably arranged on the side of the guide rail assembly, which can lock the sliding seat when the machine head is moved to a predetermined height by the sliding seat, an unlocking assembly arranged on the upper end of the guide rail assembly, the lower end of the unlocking assembly extending to a position corresponding to the locking assembly and moving downward to contact the locking assembly under the action of external force, so that the locking assembly is unlocked from the sliding seat, and the sliding seat drives the machine head to move to the uppermost end of the guide rail assembly under the driving of the elastic reset member, and at least two pot bodies capable of being placed on the base, the shape of the pot body being matched with the machine head. One or more first sensors are arranged on the handle of each pot body, a plurality of second sensors are arranged on the machine head in positions corresponding to the positions of the first sensors, the second sensors can establish signal connection with the first sensors in the corresponding positions when the machine head is covered, and the signal connection modes established by the first sensors and the second sensors on different pot bodies are different, so that the specifications of the currently used pot bodies can be recognized.

[0005] This application provides a vertical sliding guide for the air fryer head via a guide rail assembly. The air fryer head is fixedly mounted on a sliding seat via a connector, and the sliding seat carries the air fryer head and can move up and down along the guide rail. When the user presses down the air fryer head to fit a shorter pot, the sliding seat descends accordingly, and the locking assembly automatically locks it in place when it reaches the corresponding height, thus ensuring the air fryer head is stably covered on the pot. When a taller pot needs to be used, the user operates the unlocking assembly, which releases the sliding seat. At this time, the elastic reset component (which is always in a stored state, such as being stretched or twisted) drives the sliding seat and the air fryer head to quickly rise to the top of the guide rail, making enough space for a taller pot. The height of the air fryer head of this application can be flexibly adjusted according to the pot capacity. The user only needs to press down the air fryer head to the appropriate position for automatic locking. When changing the pot, the air fryer head can be automatically reset and raised with a simple operation. The air fryer head does not need to be completely separated from the device during the entire process. This greatly simplifies operation and improves ease of use, fundamentally avoiding the risks of contamination, bumps, or loss that might arise from placing the cooktop alone. It achieves a balance between variable capacity functionality and hygiene and safety. Furthermore, first sensors (such as magnets, RFID tags, or contacts) are placed at specific locations on the handles of different pots, while multiple second sensors (such as Hall effect sensors, RFID readers, or contact switches) are positioned on the cooktop corresponding to the handle locations of different pots. When the pot is placed in the base and the cooktop closes, the first sensor at a specific location on the pot handle approaches or contacts the corresponding second sensor on the cooktop, establishing signal connections of different modes. These signal connections are transmitted to the device's control circuitry, which automatically identifies which pot is currently being used and accordingly calls the preset cooking program (such as temperature and time) that matches the pot's capacity. This design eliminates the need for users to manually select the pot type or program, achieving intelligent adaptation, improving the automation and accuracy of cooking, enhancing the user experience, and also serving as a safety checkpoint, such as confirming whether the pot is correctly placed.

[0006] In some embodiments, The pot consists of three parts, and a second sensor is located on both sides of the machine head, aligned in a straight line; among them: The first pot body has two first sensors, which are symmetrically arranged on the two handles, and one of the first sensors corresponds to the second sensor. The second pot body has two first sensors, which are symmetrically arranged on the two handles, and one of the first sensors corresponds to the second sensor. The third pot body has two first sensors, which are located on its two handles and correspond one-to-one with the second sensors.

[0007] This layout utilizes sensor combinations to form unique identification codes, enabling the device to accurately determine the type of pot currently in use and automatically apply the corresponding cooking parameters. This design is not only reliable and simple in structure, but also eliminates the need for complex circuitry or coding components on the pot itself, reducing costs and manufacturing complexity. It also avoids identification errors caused by an excessive number or disorganized placement of sensors, improving system stability and user experience consistency. Furthermore, the two primary sensors on the same pot handle are arranged symmetrically, allowing for non-directional placement of the pot and further simplifying user operation.

[0008] In some embodiments, the sliding seat has a plurality of lock holes vertically spaced apart on its side; the locking assembly includes a first elastic member extending laterally and a locking block, one end of the first elastic member is connected to the guide rail assembly and the other end is connected to the locking block, and is able to push the locking block into the corresponding lock hole; the end of the locking block forms a first inclined surface, and a second inclined surface is formed at the lower end of the unlocking assembly.

[0009] The locking assembly uses a horizontally positioned elastic element (such as a spring) to push against a locking block. When the sliding seat moves down and its sidewall contacts the first inclined surface at the top of the locking block, the locking block is squeezed back under the guiding action of the inclined surface, overcoming the elastic force of the elastic element. Once the sliding seat continues to move down until a certain locking hole aligns with the locking block, the elastic element immediately pushes the locking block into that locking hole, achieving mechanical interlocking and firmly locking the sliding seat at that height. This combination of inclined surface guidance and elastic buckle achieves automatic, step-by-step locking during the downward movement, eliminating the need for additional manual locking operations and providing a smooth user experience. This embodiment achieves automatic, multi-position locking of the machine head during the downward pressing process. When the user presses down the machine head, they can feel a clear sense of the position and it can stably stop at the required height, precisely matching different sized pots. This design eliminates complex adjustment or fixing steps, making the capacity switching operation intuitive, definite, and reliable, improving the product's ease of use and human-computer interaction experience.

[0010] In some embodiments, the side of the guide rail assembly forms a receiving cavity for accommodating the locking assembly, and the end of the first elastic member away from the locking block is connected to the inner wall of the receiving cavity; wherein, the side of the guide rail assembly has a through hole corresponding to the position of the locking block, for the locking block to pass through and be inserted into the corresponding lock hole.

[0011] By creating a specially designed receiving cavity on the side of the guide rail assembly, the first elastic element and the locking block are integrally housed within it. This cavity provides a stable mounting base and operating space for the locking assembly, preventing components from being exposed. Through holes at corresponding locations allow only the end of the locking block to protrude and engage with the locking hole on the sliding seat. This design encapsulates the moving parts inside or on the side of the guide rail, resulting in a more compact and streamlined structure. It effectively prevents external foreign objects from interfering with the locking action, ensuring long-term stability and reliability.

[0012] In some embodiments, the guide rail assembly includes: two symmetrically arranged guide rails, a sliding seat slidingly engaging with the guide rails; and a mounting base disposed on the top of the two guide rails and connected to an elastic reset member.

[0013] Two symmetrically arranged guide rails provide balanced and stable bidirectional sliding guidance for the sliding seat, preventing it from tilting or jamming during movement and ensuring smooth lifting of the machine head. Mounting seats are installed at the top of the two guide rails, providing a centralized and stable support point for the upper elastic reset component, ensuring effective transmission of the reset force. This design improves the mechanical performance of the core moving parts, making height adjustment smoother and more reliable.

[0014] In some embodiments, the unlocking component includes: an unlocking member and a second elastic member; the unlocking member has a concave structure with an opening facing downward and a third inclined surface that matches the second inclined surface; one end of the second elastic member is connected to the upper end of the unlocking member, and the other end is connected to the top of the guide rail assembly.

[0015] The unlocking component is designed as a downward-opening concave shape, with its lower third bevel matching the second bevel of the locking block. When the user applies force to the unlocking component (such as pressing a button), the unlocking component moves downward against the resistance of the second elastic element, and its third bevel contacts and presses against the second bevel of the locking block. Through the interaction of the bevels, the lateral force is converted into a lateral retraction force of the locking block, forcing it to exit the lock hole of the sliding seat, thus unlocking it. The second elastic element then drives the unlocking component to automatically reset after the operation. This bevel-triggered mechanism efficiently converts the user's simple vertical pressing force into lateral displacement of the locking block, achieving one-button unlocking. The user only needs to press the unlocking component to easily unlock the sliding seat through the bevel transmission; the operating force is small and the feel is clear. After releasing, the unlocking component automatically resets, ready for the next use. This design simplifies the unlocking action to the extreme, improving the convenience and comfort of operation.

[0016] In some embodiments, the elastic reset element is a coil spring.

[0017] The use of a coil spring as the reset power source provides a stable and durable reset driving force. Its structure facilitates placement in limited spaces, and its rapid and powerful rebound action ensures that the machine head reliably resets to the top ready position under various conditions. The durability of the coil spring also guarantees that the product maintains stable performance even after long-term, frequent use.

[0018] In some embodiments, the head unit includes: a housing and a heating element disposed within the housing; the housing includes a cover with vents and a top cover disposed above the cover, and the heating element is disposed corresponding to the vents.

[0019] In some embodiments, the bottom of the pot body is provided with pot feet; the surface of the base is provided with two slide rails along the movement trajectory when the pot body is placed in, and the slide rails are used to limit the pot feet.

[0020] This embodiment optimizes the placement of the pot on the base. Pot feet (such as protrusions or sliders) are provided at the bottom of the pot, and a sliding rail corresponding to the pot's placement trajectory is provided on the base surface. When the user places the pot, the pot feet move along the sliding rail, which not only guides but also limits the pot feet. This design ensures that the pot can be easily and accurately pushed to the ideal position aligned with the center of the motor head, preventing misalignment and providing a reliable foundation for the smooth descent and closing of the motor head. Through the cooperation of the pot feet and the sliding rail, precise positioning and guidance of the pot are achieved. Users do not need to exert effort to align; they only need to push the pot into place along the sliding rail, greatly simplifying the operation and improving ease of use. At the same time, the limiting function of the sliding rail also prevents the pot from shifting due to external forces during cooking, enhancing operational stability and safety. Furthermore, this structural design makes the product easier to pass safety regulations (e.g., the pot is less likely to slip when tested on a 15-degree inclined surface), further improving the overall reliability of the product.

[0023] To make the objectives, technical solutions, and advantages of this invention clearer, the invention will be further described in detail below with reference to specific embodiments and the accompanying drawings. It should be understood that these descriptions are merely exemplary and not intended to limit the scope of the invention. Furthermore, descriptions of well-known structures and techniques are omitted in the following description to avoid unnecessarily obscuring the concept of the invention.

[0024] The present invention provides an air fryer with automatic lifting and pot body recognition functions, comprising: a base 1, a guide rail assembly 2, a sliding seat 3, a heating head 4, an elastic reset component 5, a locking assembly 6, an unlocking assembly 7, and at least two pot bodies 8.

[0025] Specifically, the base 1, serving as the support platform for the entire device, is typically made of heat-resistant plastic or metal sheet. The guide rail assembly 2 is vertically fixed to one side of the base 1, and can be connected to the base 1 via screws or integral molding. The sliding seat 3 forms a sliding fit with the guide rail assembly 2; that is, the sliding seat 3 is equipped with a groove or pulley, allowing it to move smoothly up and down along the vertical track set by the guide rail assembly 2. The heating head 4 is fixedly mounted on the sliding seat 3 and rises and falls together with it. The heating head 4 is connected to an external power source via a flexible power cord for power supply; this flexible power cord is strategically laid out along the guide rail assembly 2 with sufficient slack to ensure that the heating head 4 is not pulled during lifting and lowering, while also preventing wire tangling or wear, ensuring electrical safety. One end of the elastic reset member 5 is connected to the upper end of the guide rail assembly 2, while the other end is connected to the sliding seat 3. This elastic reset member 5 is stretched or twisted when the sliding seat 3 moves downwards, accumulating elastic energy. The locking component 6 is movably disposed on the side of the guide rail assembly 2, and can automatically lock the sliding seat 3 in a predetermined position when the sliding seat 3 moves the head 4 to a certain height. The unlocking component 7 is disposed at the upper end of the guide rail assembly 2, and its lower end extends to a position corresponding to the locking component 6; when the user applies a downward external force, the unlocking component 7 moves down and contacts the locking component 6, triggering the locking component 6 to release the locking of the sliding seat 3. In this way, the sliding seat 3, driven by the elastic energy stored in the elastic reset component 5, automatically drives the head 4 to move quickly upward to the uppermost end of the guide rail assembly 2, thereby raising the head 4 to make room for a larger pot body 8. The at least two pot bodies 8 can be placed on the base 1, and their depths or heights are different, but the shape of their upper openings matches the lower contour of the head 4 to ensure sealed cooking. With the above structure, when it is necessary to change the pot body, the user first operates the unlocking component 7, causing the machine head 4 to automatically rise to the preparatory position at the top of the guide rail. Then, the pot body 8 can be safely removed or placed in, without being limited by the height of the pot body. After placing the required pot body 8, the user presses down the machine head 4 to the appropriate position, and the locking component 6 will automatically lock it, thus stably covering the pot body 8. Alternatively, the machine head 4 can be adjusted to the corresponding height first, and then the corresponding pot body 8 can be placed in. The entire process achieves flexible, convenient, and safe changes in pot capacity.

[0026] To achieve automatic identification of the pot body 8's dimensions and intelligent adaptation to the cooking program, this air fryer is equipped with corresponding sensing devices on the pot body 8 and the head unit 4. Specifically, a first sensor 81, such as a magnet or RFID tag, is installed at a specific position on the handle of each pot body 8. A second sensor 41, such as a Hall sensor or RFID reader, is installed on both sides below the head unit 4 at positions corresponding to the handles of the pot body 8.

[0027] Specifically, this embodiment includes three different capacity pot bodies 8. Two second sensors 41 on either side of the machine head 4 are positioned on the same horizontal line and are labeled 41A and 41B respectively, used to sense the positions of the left and right handles. The first sensors 81 of the three pot bodies 8 are arranged differently to achieve unique identification. The first sensor 81 of the first pot body is provided in two places, which are symmetrically arranged on the two handles, and one of the first sensors 81 corresponds to the position of the second sensor 41A.

[0028] The second pot body has two first sensors 81, which are symmetrically arranged on the two handles, and one of the first sensors 81 corresponds to the position of the second sensor 41B.

[0029] The third pot body has two first sensors 81, which are respectively located on its two handles and correspond one-to-one with the second sensors 41A and 41B.

[0030] When the user places the pot body 8 into the container and presses down the machine head 4 to the closed position, the second sensors 41A and 41B on the machine head 4 will detect whether there is a signal from the first sensor 81 at the corresponding handle position. Based on the signal combination status of the sensors on both sides (e.g., signal on the left, no signal on the right; no signal on the left, signal on the right; signal on both sides), the control system can uniquely determine which size of pot body 8 is being used. After identification, the device automatically calls the pre-stored cooking temperature and time program that is best matched to the pot body 8. The user does not need to manually select or set anything, achieving an intelligent operating experience of "identify upon placement, start cooking upon closing." This design not only improves the convenience and accuracy of use but also avoids the problem of poor cooking results due to incompatibility between the pot body 8 and the program. Furthermore, the two first sensors 81 on the same pot body handle are arranged symmetrically, eliminating the need to distinguish the orientation when placing the pot, further simplifying user operation.

[0031] Furthermore, in one specific embodiment, the sliding seat 3 has a plurality of vertically spaced locking holes 31 on its side. The locking assembly 6 includes a first elastic member 61 extending laterally and a locking block 62. One end of the first elastic member 61 is connected to the guide rail assembly 2, and the other end is connected to the locking block 62. The continuous elastic force it provides can push the locking block 62 to move outward and insert it into a corresponding locking hole 31 on the side of the sliding seat 3, thereby achieving mechanical locking.

[0032] It is worth noting that the end of the locking block 62 is designed as a triangular structure, forming a first inclined surface 621. When the sliding seat 3 moves downward, its sidewall first contacts the first inclined surface 621. Under the guidance of the inclined surface, the locking block 62 is squeezed and retracts inward against the elastic force of the first elastic member 61. Once the sliding seat 3 continues to move downward until a certain locking hole 31 aligns with the locking block 62, the first elastic member 61 immediately pushes the locking block 62 into the locking hole 31, completing the automatic locking. Preferably, the first elastic member 61 is a spring, and the locking block 62 is made of wear-resistant metal or high-strength engineering plastic.

[0033] Based on this, a receiving cavity 21 for accommodating the entire locking assembly 6 can be further formed on the side of the guide rail assembly 2. The end of the first elastic member 61 away from the locking block 62 is fixedly connected to the inner wall of the receiving cavity 21. Correspondingly, a through hole 22 is provided on the side of the guide rail assembly 2 at the position where the locking block 62 extends. The through hole 22 allows the locking block 62 to pass through and extend so that it can be inserted into the locking hole 31 of the sliding seat 3, while the receiving cavity 21 protects most of the structure of the locking block 62 and the first elastic member 61 inside, avoiding exposure and contamination.

[0034] For the guide rail assembly 2 itself, a preferred configuration is to symmetrically arrange two guide rails 23. The two sides of the sliding seat 3 slide in engagement with these two guide rails 23, thereby achieving balanced and stable bidirectional guidance. Furthermore, a mounting base 24 is connected to the top of the two guide rails 23. This mounting base 24 is used to centrally mount and fix the upper end of the elastic reset member 5, providing a stable fulcrum for the reset action. In this way, the rigidity and smoothness of the entire lifting structure are ensured. Specifically, the guide rails 23 are protected by an outer shell 42.

[0035] Regarding the unlocking component 7, one specific implementation includes an unlocking element 71 and a second elastic element 72. The unlocking element 71 is designed as a concave structure with its opening facing downwards, slidingly engaging with the outer side of the guide rail 23. Specifically, the lower end of the locking block 62 corresponding to the unlocking component 7 is specially machined to form a second inclined surface 622, and the lower end of the unlocking element 71 is machined with a third inclined surface 711 that matches the second inclined surface 622 on the locking block 62. One end of the second elastic element 72 is connected to the upper end of the unlocking element 71, and the other end is connected to the top of the guide rail assembly 2, i.e., the mounting base 24. It normally keeps the unlocking element 71 in its initial upper position. When the user presses the unlocking element 71, it moves downwards against the resistance of the second elastic element 72, and the lower third inclined surface 711 then contacts and presses against the second inclined surface 622 of the locking block 62. Through the interaction of the inclined surfaces, the downward pressing force is converted into a force that forces the locking block 62 to retract laterally, thereby causing the locking block 62 to exit from the lock hole 31 and unlock. After the user releases their grip, the second elastic element 72 causes the unlocking element 71 to automatically reset.

[0036] For the elastic reset element 5 that provides the reset force, a coil spring is a preferred and reliable implementation. It has a compact structure and can be mounted around an axis fixed to a mounting base 24, with one end fixed to the mounting base 24 and the other end connected to a sliding seat 3, storing and releasing energy through torsion.

[0037] The head unit 4, as the core heating component, includes a housing 42 and a heating element 43 disposed within the housing 42. The housing 42 is further composed of a cover 421 with ventilation openings and a top cover 422 disposed above the cover 421. The heating element 43 includes a heating tube and a fan, and its installation position strictly corresponds to the ventilation openings on the cover 421 to ensure that hot air can be efficiently blown downwards.

[0038] Finally, to optimize the placement experience of the pot body 8 and ensure stability, the bottom of the pot body 8 is provided with pot feet 82. These pot feet 82 can be two strip-shaped protrusions or four independent support points. On the surface of the base 1, along the movement trajectory of the pot body 8 when it is placed in, two parallel slide rails 11 are provided. The cross-sectional shape of the slide rails 11 matches the pot feet 82, serving to guide and limit the pot feet 82 when the pot body 8 is pushed in. Preferably, the slide rails 11 can be metal strip inserts or directly integrally formed with the base 1, with a height of approximately 2 to 5 millimeters, sufficient to prevent the pot body 8 from shifting during cooking or slipping during tilt tests.

[0039] Alternatively, an anti-slip pad can be provided on the base 1, and the anti-slip pad will contact the bottom of the pot body 8 after the pot body 8 is placed on the base 1. This also prevents the pot body 8 from shifting due to external forces during cooking, thus enhancing the stability and safety of the operation.

[0040] It should be understood that the specific embodiments described above are merely illustrative or explanatory of the principles of the invention and do not constitute a limitation thereof. Therefore, any modifications, equivalent substitutions, improvements, etc., made without departing from the spirit and scope of the invention should be included within the protection scope of the invention. Furthermore, the appended claims are intended to cover all variations and modifications falling within the scope and boundaries of the appended claims, or equivalent forms of such scope and boundaries.
