[0030] The end of the first arm furthest from the first pivot shaft abuts against the bottom of the mounting plate.
[0031] In one possible implementation, a limiting element is provided at the top of the guide rod, which is used to limit the mounting plate when the motor is in the target position.
[0032] In one possible implementation, a third elastic element is sleeved on the guide rod. The third elastic element is disposed between the limiting member and the mounting plate.

[0040] The air fryer provided in this application achieves physical isolation between the cooking area and the driving area by vertically dividing the main body into a first cavity and a second cavity. This not only provides convenient cooking and retrieval space for the frying bucket placed in the first cavity, ensuring user convenience and easy cleaning of the cooking cavity, but more importantly, it creates a protected environment for the motor located in the second cavity, isolating it from the high-temperature cooking area and improving reliability. Based on this structure, the frying basket is designed to rotate within the cooking cavity, and a liftable motor is used as the driving source. The motor is initially located in the second cavity. When the frying bucket is placed in the main body, the motor can rise from its initial position to the target position, so that its output shaft forms a transmission connection with the frying basket. During the cooking process, the motor drives the frying basket to continuously rotate the food within the cooking cavity, allowing all sides of the food to be alternately exposed to the hot air circulation. This effectively breaks the local hot air accumulation or lack caused by the fixed frying basket structure, effectively improves heating uniformity, and solves the technical problem of localized burning or undercooking of food.

[0065] First, those skilled in the art should understand that these embodiments are merely for explaining the technical principles of this application and are not intended to limit the scope of protection of this application. Those skilled in the art can make adjustments as needed to adapt to specific application scenarios.
[0066] Secondly, it should be noted that, in the description of the embodiments of this application, unless otherwise explicitly specified and limited, the terms "connected" and "linked" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; and they can refer to the internal connection of two components. Those skilled in the art can understand the specific meaning of the above terms in the embodiments of this application according to the specific circumstances.
[0067] As described in the background art, air fryers in related technologies suffer from uneven hot air distribution, resulting in uneven heating of food, localized burning, or undercooking. The inventors have discovered that the reason for this problem is that air fryers in related technologies have a fixed frying basket structure, which causes the hot air to form localized high-heat and low-heat zones inside the frying basket. This results in a gradient difference in the heating of the food, causing uneven heating, localized burning, or undercooking.
[0068] To address the aforementioned technical problems, this application provides an air fryer comprising: a main body having a first cavity and a second cavity arranged in layers along a vertical direction; a frying bucket capable of being placed in the first cavity; the frying bucket having a cooking chamber; a frying net rotatably disposed within the cooking chamber; and a motor vertically disposed within the second cavity, with the motor's output shaft extending into the first cavity; after the frying bucket is placed within the main body, the motor can rise from an initial position to a target position, and at the target position, it is connected to the frying net via a transmission to drive the frying net to rotate within the cooking chamber.
[0069] The air fryer provided in this application achieves physical isolation between the cooking area and the driving area by vertically dividing the main body into a first cavity and a second cavity. This not only provides convenient cooking and retrieval space for the frying bucket placed in the first cavity, ensuring user convenience and easy cleaning of the cooking cavity, but more importantly, it creates a protected environment for the motor located in the second cavity, isolating it from the high-temperature cooking area and improving reliability. Based on this structure, the frying basket is designed to rotate within the cooking cavity, and a liftable motor is used as the driving source. The motor is initially located in the second cavity. When the frying bucket is placed in the main body, the motor can rise from its initial position to the target position, so that its output shaft forms a transmission connection with the frying basket. During the cooking process, the motor drives the frying basket to continuously rotate the food within the cooking cavity, allowing all sides of the food to be alternately exposed to the hot air circulation. This effectively breaks the local hot air accumulation or lack caused by the fixed frying basket structure, effectively improves heating uniformity, and solves the technical problem of localized burning or undercooking of food.
[0070] It should be noted that an air fryer contains a heating element (heating wire / heating tube) and a fan. The heating element is located at the top of the fryer (usually in the center of the top). When powered on, it generates high temperature and is the source of heat. The fan is located above or around the heating element. When powered on, the fan rotates at high speed and powerfully blows the heat generated by the heating element onto the food in the form of hot air.
[0071] To make the above-mentioned objectives, features, and advantages of the embodiments of this application more apparent and understandable, the technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only a part of the embodiments of this application, and not all of them. All other embodiments obtained by those skilled in the art based on the embodiments of this application without creative effort are within the scope of protection of this application.
[0072] Please refer to the attached document. Figure 1-14 This application provides an air fryer, comprising:
[0073] The main body 10 has a first cavity 101 and a second cavity 102 arranged in layers along the vertical direction;
[0074] The fryer bucket 20 can be placed inside the first cavity 101; the fryer bucket 20 has a cooking cavity 201;
[0075] The frying net 30 is rotatably mounted inside the cooking cavity 201;
[0076] The motor 40 is vertically mounted in the second cavity 102, and the output shaft of the motor 40 can extend into the first cavity 101. After the frying bucket 20 is placed in the main body 10, the motor 40 can rise from the initial position to the target position, and at the target position, it is connected to the frying net 30 to drive the frying net 30 to rotate in the cooking cavity 201.
[0077] In this embodiment, the air fryer's frying drum 20 and body 10 can be designed as a drawer. Please refer to [link / reference]. Figure 2 As shown, the main body 10 has a first cavity 101 and a second cavity 102. The first cavity 101 serves as the cooking zone, housing the frying bucket 20 and circulating high-temperature hot air. The second cavity 102 serves as the drive and transmission zone, housing the motor 40 and its lifting-related components. This layered design of the main body 10 achieves physical isolation of the functional areas, effectively preventing the high temperatures, oil stains, and food debris generated during cooking from directly intruding into and damaging the precision drive components such as the motor 40, thus improving the reliability and lifespan of the equipment. Simultaneously, it provides an independent and controllable installation and operating space for the lifting movement of the motor 40. Please refer to... Figure 3 As shown, the fryer bucket 20 is an independent and separable cooking container that can be placed inside the first cavity 101, making it convenient for users to load and unload food and clean the fryer bucket 20 and the cooking cavity 201.
[0078] In this embodiment of the application, please refer to Figure 1As shown, the frying net 30 is rotatably mounted within the cooking cavity 201, enabling the food to transition from a static, fixed state to a dynamic, rotating state. When the frying net 30 rotates, the food on it changes its position and orientation within the cooking cavity 201. This breaks down the static "high-heat zone" and "low-heat zone" that might be formed due to a fixed hot air outlet, allowing all surfaces of the food to be more evenly exposed to the circulating hot air, thus promoting uniform heating and preventing localized burning or uncooking.
[0079] In this embodiment of the application, please refer to Figure 2 As shown, when the frying bucket 20 is not placed into the first cavity 101, the motor 40 is in its initial position, and the top of its output shaft does not obstruct the insertion and removal of the frying bucket 20. Please refer to... Figure 4 As shown, the motor 40 only rises to the target position for connection after the frying bucket 20 is placed in place. This ensures that the user's ease of operation of the frying bucket 20 is not affected by the rotating structure. The motor 40 is the power source that drives the rotation of the frying net 30. The detachable connection achieved through lifting allows the motor 40 to reliably transmit power to the frying net 30 inside the detachable frying bucket 20, thereby enabling the frying net 30 to rotate the food.
[0080] The air fryer provided in this application achieves physical isolation between the cooking area and the driving area by vertically dividing the body 10 into a first cavity 101 and a second cavity 102. This not only provides convenient cooking and retrieval space for the frying bucket 20 placed in the first cavity 101, ensuring user convenience and easy cleaning of the cooking cavity 201, but more importantly, it creates a protected environment for the motor 40 located in the second cavity 102, isolating it from the high-temperature cooking area and improving reliability. Based on this structure, the frying net 30 is configured to rotate within the cooking cavity 201, and a liftable motor 40 is used as the driving source. The motor 40 is initially located in the second cavity 102. When the frying bucket 20 is placed in the body 10, the motor 40 can rise from its initial position to the target position, so that its output shaft forms a transmission connection with the frying net 30. During the cooking process, the motor 40 drives the frying net 30 to continuously rotate the food in the cooking cavity 201, so that all sides of the food are alternately exposed to the hot air circulation. This effectively breaks the local hot air accumulation or lack caused by the fixed frying net structure, effectively improves the heating uniformity, and solves the technical problem of local scorching or undercooking of the food.
[0081] In one possible implementation, please see Figure 4As shown, the air fryer also includes a support 50, which is rotatably mounted on the bottom wall of the frying drum 20. One end of the support 50 is located inside the cooking cavity 201 and is used to connect with the frying net 30 to drive the frying net 30 to rotate. The other end of the support 50 is located on the side of the bottom wall of the frying drum 20 away from the cooking cavity 201 and is used to connect with the motor 40 so that the support 50 rotates under the drive of the motor 40.
[0082] In this embodiment, the bracket 50 is an important transmission medium and support carrier connecting the rotation function of the frying net 30 and the separability of the frying barrel 20.
[0083] On the one hand, the support 50, as an independent transmission component, has one end fixedly connected to the frying net 30 inside the cooking cavity 201, and the other end prepared to connect to the motor 40 on the outer bottom of the frying bucket 20. This allows the power of the motor 40 to be efficiently and stably transmitted to the frying net 30 through a defined and structurally robust fulcrum (support 50), avoiding the eccentricity, swaying, or unreliable connection problems that may occur if the power is directly applied to the frying net 30, ensuring smooth rotation, and thus achieving modular and reliable connection of power transmission.
[0084] On the other hand, when the frying bucket 20 is placed into the main body 10, the interface on the outside of the bracket 50 connects with the output shaft of the rising motor 40, and the power is connected; when the frying bucket 20 is removed, the power connection is automatically disconnected, and the frying net 30 is taken away along with the bracket 50 and the frying bucket 20. Users can enjoy the function of "automatic rotation of the frying net" and the convenience of "whole frying bucket removal and cleaning" without having to perform any additional locking or docking operations, providing a seamless and natural user experience.
[0085] On the other hand, by placing the transmission interface (the connection point between the bracket 50 and the motor 40) on the outside of the bottom wall of the frying drum 20, the mechanical connection part is relatively isolated from the high-temperature, oily interior of the cooking cavity 201, which helps to improve the long-term reliability of the transmission components. At the same time, as part of the sub-component of the frying drum 20, the maintenance or cleaning of the bracket 50 can be carried out together with the frying drum 20, making maintenance convenient.
[0086] In one possible implementation, please see Figure 5 and Figure 6 As shown, the bracket 50 includes a support plate 51, a first boss 511 and a plurality of second bosses 512 disposed on the support plate 51. The first boss 511 is located at the center of the support plate 51, and the plurality of second bosses 512 are evenly spaced along the circumference of the first boss 511.
[0087] Please see Figure 8As shown, the blasting net 30 is provided with a first slot 301 and a plurality of second slots 302. The first slot 301 can cooperate with the first protrusion 511, and the plurality of second slots 302 can cooperate with the plurality of second protrusions 512 respectively to position the blasting net 30 on the support plate 51.
[0088] In this embodiment, the engagement of the first protrusion 511 at the center with the first slot 301 ensures that the frying net 30 can be quickly and accurately positioned concentrically with the support 50 (i.e., the axis of rotation), avoiding rotational instability and vibration that may be caused by eccentric installation of the frying net 30. Simultaneously, the engagement of multiple second protrusions 512 evenly spaced circumferentially with the second slots 302 constrains the relative circumferential rotation between the frying net 30 and the support plate 51 at multiple angles, ensuring that the driving force of the motor 40 can be completely transmitted to the frying net 30 without slippage or delay. This achieves rapid and precise radial and circumferential positioning. During user or assembly, simply aligning the slots of the frying net 30 with the protrusions and placing it down automatically completes precise positioning and basic fixation. The tight engagement of the protrusions and slots forms an effective circumferential and radial mechanical lock, preventing the frying net 30 from shifting or loosening even during high-speed rotation and impact from food loads, ensuring the safety and stability of the cooking process.
[0089] Furthermore, the support plate 51, as a complete load-bearing surface, distributes the weight of the frying net 30 and the food on it, as well as the inertial force generated during rotation, to multiple sturdy support points through the cooperation of the center and multiple protrusions around it. This enhances the stability of the load-bearing structure, preventing the frying net 30 from tilting, warping, or detaching from the drive components under load, thus ensuring the reliability of the rotation function under heavy load conditions.
[0090] In one possible implementation, please see Figure 5 As shown, the bracket 50 also includes a transmission part 52, which is disposed at the bottom of the support plate 51. The transmission part 52 has a plug slot 521 at one end facing the motor 40.
[0091] The output shaft of the motor 40 is provided with a plug-in part 41 that matches the plug-in slot 521. The plug-in part 41 can be inserted into the plug-in slot 521 when the motor 40 rises to the target position, so that the plug-in part 41 drives the transmission part 52 to rotate circumferentially.
[0092] In this embodiment, when the frying barrel 20 is placed in place and the motor 40 rises, the plug part 41 is precisely inserted into the plug slot 521, and the two immediately form a rigid connection in the circumferential direction, ensuring that the torque of the motor 40 can be directly transmitted to the transmission part 52 with almost no loss, thereby driving the entire bracket 50 and the frying net 30 to rotate. The transmission path is direct, efficient and reliable, thus realizing efficient and reliable plug-and-play power transmission.
[0093] Furthermore, the tight fit between the insertion part 41 and the insertion slot 521 provides effective support and constraint for the transmission part 52 in the radial direction (i.e., the left-right direction), ensuring the coaxiality of power transmission. This prevents the bracket 50 from radially running or swaying during rotation, thereby ensuring the smooth rotation of the mesh blasting 30, reducing vibration and noise, and achieving uniform heating.
[0094] In one possible implementation, please see Figure 5 and Figure 7 As shown, both the insertion groove 521 and the insertion part 41 have square cross sections, so that the transmission part 52 locks in the circumferential direction after it is engaged with the insertion part 41.
[0095] In this embodiment, when the plug-in part 41 is inserted into the plug-in slot 521, the four planes of the two fit tightly together, thus forming a complete, slip-free rigid connection in the circumferential direction. This allows the output torque of the motor 40 to be completely and without loss transmitted to the bracket 50 through these four contact surfaces, ensuring that the transmission efficiency of the driving force reaches its maximum, completely avoiding the loss of rotation or stoppage of the mesh 30 due to slippage, thereby achieving reliable circumferential locking and torque transmission.
[0096] In some embodiments, see Figure 5 and Figure 7 As shown, a chamfer can be provided around the top edge of the plug part 41 to guide the plug part 41 into the plug groove 521. During this process, the transmission part 52 and / or the plug part 41 can be adaptively rotated by a certain angle so that the plug part 41 and the plug groove 521 can naturally and accurately complete the insertion, improving the smoothness of the user experience.
[0097] In one possible implementation, please see Figure 4 As shown, the air fryer also includes a lifting mechanism 60, which includes a rocker assembly 61 and a top rod assembly 62.
[0098] The rocker assembly 61 is disposed in the second cavity 102 and hinged to the body 10. The first end of the rocker assembly 61 can provide the motor 40 with a lifting force.
[0099] The top rod assembly 62 is vertically telescopically disposed within the second cavity 102, and the top of the top rod assembly 62 extends at least partially into the first cavity 101. After the frying barrel 20 is placed inside the body 10, the bottom wall of the frying barrel 20 can press down on the top of the top rod assembly 62, causing the top rod assembly 62 to press down on the second end of the rocker assembly 61, so that the first end of the rocker assembly 61 lifts the motor 40 to the target position.
[0100] In this embodiment, by setting up a lifting mechanism 60, the following can be achieved: the user places the frying bucket 20 → the bottom wall of the frying bucket 20 presses down on the top rod assembly 62 → the top rod assembly 62 presses down on the second end of the rocker assembly 61 → the first end of the rocker assembly 61 lifts the motor 40. The entire process requires no electronic sensors, switches, or additional user operation, achieving ultimate convenience of "ready upon placement," and completely hiding the complex technical process, realizing fully automatic, purely mechanical triggering from "user action" to "functional readiness."
[0101] Moreover, both the rocker assembly 61 and the push rod assembly 62 are composed of simple mechanical components (such as rods, shafts, and plates) without any precision electronic components. Their operation is based on physical contact and transmission, resulting in high reliability. They are not easily affected by temperature, oil stains, or humidity in the kitchen environment, have a long service life, and are inexpensive to manufacture.
[0102] Simultaneously, this ensures that the motor 40 will only rise and connect to the frying net 30 when the frying bucket 20 is properly positioned and the top rod assembly 62 is pressed down. Conversely, when the frying bucket 20 is lifted, the pressure on the top rod assembly 62 is released, and the motor 40 automatically descends and disengages under the action of the reset mechanism (such as a spring). This constitutes a natural mechanical safety interlock, preventing the motor 40 from malfunctioning when the frying bucket 20 is not in place, and also ensuring that the power connection is automatically disconnected before the frying bucket 20 is removed, thus improving operational safety.
[0103] It should be noted that, please refer to Figure 1 and Figure 4 As shown, the first cavity 101 and the second cavity 102 of the main body 10 are separated by a wall panel 11, which has a conical structure with a downwardly recessed central area. The insertion part 41 of the motor 40 extends from the central area of the wall panel 11, and multiple push rod assemblies 62 are arranged around the circumference of the motor 40. This allows the insertion part 41 of the motor 40 to be positioned lower in the vertical direction, avoiding interference between the insertion part 41 and the bottom wall of the frying bucket 20 when it is placed. Moreover, due to the influence of fitting tolerances and gravity, after the frying bucket 20 is placed, it will fall a certain distance in the vertical direction before contacting and pressing down the push rod assembly 62 until the motor 40 rises to the target position. When the frying bucket 20 is removed, it is raised a certain distance in the vertical direction. At this time, the push rod assembly 62 and the rocker assembly 61 automatically reset, and the motor 40 descends to the initial position, thereby removing the frying bucket 20.
[0104] When the frying drum 20 is placed, the downward pressure of its bottom wall is evenly transmitted to the rocker assembly 61 below through multiple push rod assemblies 62. This uniform load distribution avoids problems such as tilting, jamming, or excessive local stress on the wall panel caused by unilateral pressure, ensuring that the frying drum 20 can be pressed down smoothly and horizontally, thereby driving the rocker assembly 61 to move in a balanced manner, and finally lifting the motor 40 vertically and smoothly, avoiding jamming or uneven wear during the lifting process.
[0105] In one possible implementation, please see Figure 9 and Figure 10 As shown, the rocker assembly 61 includes a pivot boss 611, a first pivot shaft 612, and a plate 613. The pivot boss 611 is fixedly connected to the body 10, and the plate 613 is hinged to the pivot boss 611 at the first pivot shaft 612.
[0106] The plate 613 includes a first arm 6131 and a second arm 6132 arranged at an angle. The first arm 6131 and the second arm 6132 intersect at the position of the first pivot shaft 612. The first arm 6131 is used to lift the motor 40, and the second arm 6132 is connected to the push rod assembly 62.
[0107] In this embodiment, the combination of the pivot boss 611 and the first pivot shaft 612 creates a fixed and solid rotation fulcrum for the plate 613 on the body 10. This ensures that the plate 613 can rotate precisely and stably around a defined axis when subjected to the downward pressure from the push rod assembly 62 and the reaction force from the upward lifting motor 40. This avoids motion inaccuracy, jamming, or additional wear caused by fulcrum wobbling or displacement, thereby ensuring the long-term repeatability accuracy of the lifting action.
[0108] The plate 613 is designed with an angled first arm 6131 and a second arm 6132, thus forming an angular lever. The vertical downward pressure acting on the end of the second arm 6132 (the point of force application), transmitted by the weight of the frying bucket 20 through the push rod assembly 62, can be effectively converted into an upward pushing force acting on the end of the first arm 6131 (the point of application). Through the lever action, the entire drive module, including the motor 40 and its mounting structure, can be easily and reliably lifted without increasing the user's operating force (i.e., the weight of the frying bucket).
[0109] The entire rocker assembly 61 consists of only a few simple parts (bosses, shafts, and plates), resulting in a very simple and compact structure, making it ideal for installation within the space-constrained second cavity 102. Its power transmission path (push-rod assembly 62 presses down on the second arm 6132 → plate 613 rotates around the first pivot shaft 612 → first arm 6131 raises the motor 40) is direct and efficient, with almost no intermediate energy loss, and the action response is rapid and predictable. This simplicity also brings advantages such as high reliability, low failure rate, and ease of manufacture.
[0110] Moreover, this structure physically establishes a necessary and synchronous reverse motion relationship between "the second arm 6132 pressing down" and "the first arm 6131 raising": the motor 40 will only be raised when the frying barrel 20 actually presses down the top rod assembly 62 and the second arm 6132. Conversely, when the pressure is released, the motor 40 descends under the action of the reset mechanism, and the second arm 6132 rises. This forms a clear motion logic and mechanical interlock, preventing disordered movement of components.
[0111] In one possible implementation, the length of the first arm 6131 is greater than the length of the second arm 6132.
[0112] In this embodiment, the downward stroke of the frying drum 20 is limited by its own weight and structure (especially for drawer-type frying drums), resulting in a relatively small displacement. When the second arm 6132 (short power arm) is pressed down by this small displacement, according to the lever principle, a magnified and larger vertical upward displacement is generated at the end of the first arm 6131 (long resistance arm). This magnified displacement is crucial to ensuring that the motor 40 can rise fully and reliably to the "target position," enabling its insertion part 41 to fully and securely engage with the insertion slot 521 of the bracket 50. It compensates for the minor deformations that may occur due to mechanism clearances, manufacturing tolerances, and long-term use, ensuring that the docking action is performed correctly every time.
[0113] In one possible implementation, please see Figure 9 and Figure 11 As shown, the top rod assembly 62 includes a first rod 621 and a second rod 622 coaxially arranged. One end of the first rod 621 is fixedly connected to the body 10 in the vertical direction. The second rod 622 is sleeved on the first rod 621 and can move relative to the first rod 621 in the vertical direction. One end of the second rod 622 is used to contact the bottom wall of the frying barrel 20, and the other end is used to contact the second arm 6132.
[0114] In this embodiment, the first rod 621 is fixed to the body 10, providing a vertical and fixed-position rigid reference axis. The second rod 622 can slide along the first rod 621, forming a precise linear guide mechanism. When the frying barrel 20 is pressed down, the force is transmitted through the top of the second rod 622, forcing it to move downward along the strictly vertical path defined by the first rod 621. This ensures that the direction of the force applied to the second arm 6132 of the rocker assembly is always perpendicular to the plane of the rocker or consistent with the design direction, avoiding mechanism jamming, additional wear, or efficiency loss caused by lateral force, and ensuring the accuracy and reliability of the action.
[0115] Furthermore, the relatively movable second rod 622 constitutes a "floating" force transmission rod. Its top end contacts the bottom wall of the frying drum 20, and its bottom end contacts the second arm 6132 of the rocker assembly. This design can adapt to minute dimensional tolerances and assembly clearances. Even if there are slight deviations in the placement position of the frying drum 20 or the initial angle of the rocker assembly 61, the second rod 622 can be finely adjusted within its sliding range to ensure stable and reliable contact at both ends, avoiding the problem of force transmission failure due to "lock-in" or "loose connection".
[0116] In one possible implementation, please see Figure 9 and Figure 11 As shown, the push rod assembly 62 also includes a first elastic element 623, which is disposed between the first rod body 621 and the second rod body 622. The first elastic element 623 is used to reset the second rod body 622.
[0117] In this embodiment, the first elastic element 623 (typically a spring) can be pre-compressed and installed between the first rod 621 and the second rod 622. When the fryer bucket 20 is placed in and presses down on the second rod 622, the first elastic element 623 is further compressed and stores energy. Once cooking is finished and the fryer bucket 20 is removed by the user, the downward pressure applied to the second rod 622 disappears, and the elastic potential energy stored in the first elastic element 623 is immediately released, pushing the second rod 622 to slide upward along the first rod 621 until it returns to its initial position. This provides the top rod assembly 62 with an automatic, fast, and deterministic reset action without external force, ensuring that the mechanism is in a ready state after each use, prepared for the next placement of the fryer bucket and triggering of the connection.
[0118] Furthermore, in the initial and reset states, the elastic force of the first elastic element 623 maintains a slight upward tendency at the tip of the second rod 622. This ensures that the tip of the second rod 622 is in close contact or slightly engaged with the bottom wall of the frying bucket 20, and its bottom end is in close contact with the second arm 6132 of the rocker assembly, before the action begins. This eliminates gaps between components. When the frying bucket is placed in, the downward action is transmitted immediately without delay, making the entire lifting mechanism respond quickly, directly, and without backlash. The action transmission is precise and reliable, avoiding impact sensations, abnormal noises, or operational failures caused by gaps.
[0119] Furthermore, the reset force of the first elastic element 623 ensures that when the frying bucket 20 is lifted, the top rod assembly 62 immediately resets, causing the rocker assembly 61 to rotate under the action of a related reset mechanism (such as the second elastic element 63), thereby driving the motor 40 to descend and disengage from the frying basket. This reinforces the mechanical safety logic of "no connection without frying bucket," ensuring that the drive connection is only established during cooking, thus improving the safety of the equipment.
[0120] In one possible implementation, please see Figure 9 and Figure 11 As shown, a first limiting boss 6211 is provided on the first rod body 621. The first limiting boss 6211 is circumferentially disposed on the outer peripheral wall of the first rod body 621. The first limiting boss 6211 is slidably connected to the inner peripheral wall of the second rod body 622. The first limiting boss 6211 is used to limit the first elastic member 623.
[0121] In this embodiment, the first limiting boss 6211 serves as a rigid mechanical stop at one end of the first elastic element 623 (typically a spring). This ensures that the end of the first elastic element 623 always has a defined and stable supporting surface throughout its entire compression and rebound stroke, preventing axial movement or tilting of the first elastic element 623 under stress. This guarantees that the elastic force is always accurately transmitted along the designed axis (i.e., the axis of the push rod), making the reset action powerful, direct, and consistent, avoiding weak reset, jamming, or abnormal noise caused by inaccurate positioning of the first elastic element 623.
[0122] Furthermore, the outer peripheral surface of the first limiting boss 6211 can also slide tightly with the inner peripheral wall of the second rod 622, forming a precise cylindrical guide pair. This fit strictly constrains the movement trajectory of the second rod 622 relative to the first rod 621, ensuring that it can only slide smoothly along a strictly vertical direction (i.e., the axial direction of the first rod 621), effectively preventing radial swaying, tilting, or even jamming of the second rod 622 during movement. This is crucial for ensuring the vertical and unbiased transmission of pressure from the frying barrel 20, as well as the smoothness and precision of the entire lifting mechanism 60.
[0123] In one possible implementation, please see Figure 9 and Figure 11 As shown, a second limiting boss 6212 is also provided on the first rod body 621. The second limiting boss 6212 is circumferentially disposed on the outer peripheral wall of the first rod body 621, and the second limiting boss 6212 is slidably connected to the inner peripheral wall of the second rod body 622.
[0124] The end of the second rod 622 is provided with a limiting part 6221. When the motor 40 returns to the initial position, the limiting part 6221 contacts the second limiting boss 6212.
[0125] In this embodiment, the contact between the second limiting boss 6212 and the limiting part 6221 defines a definite and insurmountable endpoint position for the upward movement of the second rod 622 under the push of the first elastic member 623. This ensures that after each descent of the motor 40 and removal of the frying bucket 20, the entire top rod assembly 62 can accurately and stably return to the exact same initial position under the action of spring force. This consistency in reset is a prerequisite for ensuring accurate lifting trigger stroke, reliable trigger force, and successful docking when the frying bucket is placed in the next time, eliminating functional uncertainty caused by random drift of the reset position.
[0126] The second limiting boss 6212 and the first limiting boss 6211 work together to form two circumferential support surfaces on the first rod 621 that slide in contact with the inner wall of the second rod 622. This dual-point support guide effectively improves the motion stability of the second rod 622 and reduces the possibility of it tilting or getting stuck due to lateral forces.
[0127] In some embodiments, see Figure 9 and Figure 10 As shown, the second arm 6132 is provided with a clearance groove 6133 that is adapted to the first rod 621 to avoid interference between the second arm 6132 and the first rod 621 during the swinging process, while not affecting the second rod 622 pressing down on the second arm 6132.
[0128] In one possible implementation, please see Figure 4 and Figure 9 As shown, a second elastic element 63 is provided on the first rod 621, and the second elastic element 63 is coaxially arranged with the first rod 621; the second elastic element 63 is used to spring the bottom of the second arm 6132 so that when the motor 40 returns to the initial position, the plate 613 is reset.
[0129] In this embodiment, in the lifting mechanism 60, an independent second elastic element 63 is provided on the first rod 621, and the second elastic element 63 is coaxially arranged with the first rod 621. This provides an independent, direct, and directional active driving force for the resetting of the plate 613 by springing the bottom of the second arm 6132 of the rocker assembly 61. When the frying barrel 20 is removed, after the rocker assembly 62 rises under the action of the first elastic element 623, the elastic force of the second elastic element 63 will directly act on the bottom of the second arm 6132, actively pushing the entire rocker assembly 61 to rotate around the first pivot shaft 612, thereby forcibly driving the first arm 6131 to descend, so that the motor 40 can reliably return to its initial position. This ensures that regardless of whether there is friction, lubrication changes, or slight deformation in the mechanism, the rocker assembly 61 can always return to a certain initial posture, ready for the next trigger action.
[0130] Furthermore, the second elastic element 63, by continuously applying an upward force, can effectively eliminate all play in the reset direction between the plate 613 and the hinge shaft, and between the first arm 6131 and the motor mounting plate, ensuring that all components are tightly positioned. This prevents abnormal noises caused by incomplete reset, cumulative stroke errors during the next trigger, and even docking failure, ensuring that the starting point, stroke, and end point of each lifting action are consistent.
[0131] The first elastic element 623 is responsible for resetting the push rod assembly 62, and the second elastic element 63 is responsible for resetting the rocker assembly 61. The two elements work in tandem: after the frying barrel 20 is removed, the second rod 622 rises first under the action of the first elastic element 623, and then the force of the second elastic element 63 is released, pushing the rocker assembly 61 to rotate. This step-by-step, coordinated resetting mechanism allows the descent of the motor 40 and the ascent of the push rod assembly 62 to proceed more smoothly and orderly, avoiding internal impacts, vibrations, or noise that might occur from multiple components resetting rapidly at the same time, thus improving the quality of the action and the lifespan of the mechanism.
[0132] Furthermore, this design reinforces the safety logic of "no frying bucket, no connection." The forced reset force provided by the second elastic element 63 is the final mechanical guarantee to ensure that the motor 40 must descend and disengage immediately and completely after the frying bucket is removed. This avoids the possibility of the motor 40 "hovering" in a semi-connected state due to insufficient gravity or friction, physically ensuring that the drive connection is only established during cooking, thereby preventing the risk of malfunction of the motor 40 when the frying bucket 20 is not in place or not completely removed, and improving the safety of the equipment.
[0133] In one possible implementation, please see Figure 4 and Figure 9As shown, the lifting mechanism 60 also includes a mounting plate 64 and a plurality of guide rods 65 slidably connected to the mounting plate 64. The guide rods 65 are disposed in the second cavity 102 and fixed to the body 10. The mounting plate 64 can slide along the guide rods 65 in the vertical direction. The mounting plate 64 is used to mount and fix the motor 40 so as to drive the motor 40 to move in the vertical direction.
[0134] The end of the first arm 6131 away from the first pivot shaft 612 abuts against the bottom of the mounting plate 64.
[0135] In this embodiment, multiple guide rods 65 are fixed to the body 10, forming multiple rigid tracks parallel to and perpendicular to the mounting plane. The mounting plate 64 slides along these tracks, strictly constraining the movement path of the motor 40, ensuring that it can only move in a precise vertical direction, eliminating horizontal positional offset or tilt, thereby ensuring that the plug-in part 41 on the motor output shaft can accurately align and insert into the plug-in slot 521 of the bracket 50 each time, achieving automatic docking without jamming.
[0136] Mounting plate 64, acting as a rigid load-bearing platform, provides a large, stable mounting foundation for motor 40, preventing deformation during installation or under stress. When the first arm 6131 of rocker assembly 61 abuts against the bottom of mounting plate 64, its lifting force is evenly transmitted and distributed throughout motor 40 and its mounting structure via mounting plate 64, avoiding localized stress concentration. Simultaneously, the weight of motor 40 and its mounting is also evenly transmitted through mounting plate 64 to multiple guide rods 65, ensuring load-bearing stability.
[0137] The first arm 6131 of the rocker assembly swings in an arc, and its end makes point or line contact with the bottom of the mounting plate 64. Through the cooperation of the mounting plate 64 and the guide rod 65, the slightly directional pushing force from the rocker is efficiently and smoothly converted into pure vertical lift, driving the entire motor module to rise vertically. The guide rod 65 bears all the lateral force, ensuring the efficiency and smoothness of motion conversion and reducing unnecessary friction and wear.
[0138] The mounting plate 64 and multiple guide rods 65 form a robust frame structure, enhancing the overall structural rigidity of the motor 40 and its drive module within the second cavity 102. This not only makes the lifting action more stable, but more importantly, when the motor 40 is running at high speed, this structure can effectively suppress the vibration generated by the motor, preventing the vibration from being transmitted to the main body and causing additional noise. It also protects the lifting mechanism and transmission connection from vibration interference, improving the smoothness and quietness of the entire machine's operation.
[0139] In one possible implementation, please see Figure 4 and Figure 9As shown, a limiting member 66 is provided at the top of the guide rod 65. The limiting member 66 is used to limit the mounting plate 64 when the motor 40 is in the target position.
[0140] In this embodiment, the limiting member 66 mechanically sets an insurmountable final position for the upward movement of the mounting plate 64 (and the motor 40 carried thereon). When the mounting plate 64 rises under the drive of the rocker assembly 61 and contacts the limiting member 66, the lifting action immediately stops. This precisely defines the endpoint of the motor 40's ascent, i.e., the "target position." At this position, the insertion part 41 on the output shaft of the motor 40 is precisely inserted into the insertion slot 521 of the bottom bracket 50 of the frying drum 20, ensuring that the depth and position of each automatic docking are completely consistent, thereby ensuring reliable torque transmission of the power connection.
[0141] Furthermore, the limiting component 66 serves as a fixed mechanical reference point, providing a clear height benchmark for the installation and commissioning of the mounting plate 64, motor 40, and related components such as the rocker assembly 61 and push rod assembly 62. This ensures that during mass production, the endpoint position of the motor 40's lifting and lowering is strictly consistent in each machine, thereby achieving reliability and uniformity in product function and performance.
[0142] In one possible implementation, please see Figure 4 and Figure 9 As shown, a third elastic element 67 is sleeved on the guide rod 65. The third elastic element 67 is disposed between the limiting member 66 and the mounting plate 64. The third elastic element 67 is used to push the upper surface of the mounting plate 64 so that the mounting plate 64 drives the motor 40 to return to the initial position.
[0143] In this embodiment, when the frying barrel 20 is removed and the top rod assembly 62 resets, causing the first arm 6131 of the rocker assembly to no longer abut against the mounting plate 64, the third elastic element 67, which is in a compressed state, releases its stored elastic potential energy and directly and vertically pushes the upper surface of the mounting plate 64 downwards. This drives the entire mounting plate 64 and the motor 40 fixed thereon to descend smoothly and forcefully to the initial position along the guide rod 65. This ensures that the descent and reset of the motor 40 is active, positive, and independent of gravity or other indirect forces, avoiding the risk of "getting stuck" halfway due to friction, oil stains, or slight deformation, and ensuring the thoroughness and consistency of each reset action.
[0144] When the motor 40 is lifted by the rocker assembly 61, the mounting plate 64 needs to compress the third elastic element 67. This gradually increasing elastic force effectively provides a flexible endpoint for the lifting action, and combined with the rigid limit of the limiting element 66, forms a "soft-then-hard" positioning mechanism. This effectively absorbs the impact energy at the end of the lifting process, protecting the mounting plate 64, the limiting element 66, and the top threads of the guide rod 65 from hard impacts, making the docking action smoother and quieter.
[0145] When the motor 40 is raised to the target position and begins to drive the mesh blasting 30 to rotate, the third elastic element 67 is in a state of maximum compression. Its strong downward elastic force acts continuously and stably on the entire motor module through the mounting plate 64. This force, together with the upward resisting force of the first arm 6131 of the rocker assembly, forms a stable force loop at the mounting plate 64. This eliminates the gaps and wobbling that may occur between the components (such as between the rocker arm and the mounting plate, and between the guide rod and the hole in the mounting plate) under vibration, ensuring that the motor and drive shaft maintain an extremely stable posture even under high-speed operation, reducing vibration and noise, and improving transmission accuracy and durability.
[0146] The first elastic element 623 ensures the top rod resets, the second elastic element 63 ensures the rocker arm resets, and the third elastic element 67 ensures the motor resets. These three elements work sequentially in time and synergistically in mechanical action, forming a highly reliable, automatic, and complete "separation-reset" cycle. This design distributes the reset function across multiple dedicated components, rather than relying on a single mechanism, significantly improving the long-term fault tolerance and overall reliability of the entire lifting mechanism.
[0147] In one possible implementation, please see Figure 12 and Figure 13 As shown, the air fryer also includes multiple guide vanes 70, which are located at the bottom of the frying basket 30. The angle of each guide vane 70 is adjustable to adjust the ventilation direction inside the cooking cavity 201.
[0148] In this embodiment, by adjusting the angle of each guide vane 70, the mainstream direction and diffusion pattern of the hot air can be actively changed, for example, guiding the airflow from the periphery to the center, or forming a spiraling vortex. This breaks the state of relatively random airflow paths and the easy formation of fixed dead zones caused by the original fixed air outlet, allowing the hot air to be consciously guided to areas that are easily underheated, thereby achieving artificial intervention and optimization of the airflow distribution within the entire cooking cavity 201. Different ingredients (such as whole pieces of meat and small pieces of fries) or different loading volumes may have different requirements for airflow speed and direction. The adjustable guide vanes 70 provide flexible adaptability for this. Users can adjust the guide vanes 70 to the most suitable guide angle for specific ingredients as needed, for example, using a more penetrating concentrated airflow for densely piled ingredients, and a more uniform diffused airflow for flatly laid ingredients. This customizable airflow mode allows the air fryer to more accurately adapt to diverse cooking tasks, thereby achieving better cooking results and food quality.
[0149] Furthermore, the combination of the guide vanes 70 (which adjust the airflow direction) and the rotatable frying net 30 (which moves the food) forms a dual-protection system of "actively guiding airflow" and "actively moving food." Even if there is a slight unevenness in the initial distribution of airflow, the rotating food will compensate for it through its own movement; conversely, even if the food is relatively stationary, the optimized airflow can better cover its surface. The two work together, optimizing the "field" and moving the "object," to achieve three-dimensional, dynamic, and uniform heating, raising the reliability and thoroughness of solving the problem of uneven heating to a new level.
[0150] In one possible implementation, please see Figure 12 and Figure 13 As shown, the bottom of the blasting net 30 is provided with a plurality of second pivot shafts 31, which are evenly spaced in the circumferential direction along the edge of the blasting net 30.
[0151] One end of each guide vane 70 is rotatably connected to the second pivot shaft 31, and the other end can extend toward the central area of the blasting net 30.
[0152] In this embodiment, multiple second pivot shafts 31 are evenly spaced circumferentially along the edge of the frying net 30, so that the installation starting points of the guide vanes 70 are distributed at equal angles. This ensures that hot air entering from the side wall or bottom of the fryer can be uniformly and symmetrically captured and guided when it first encounters this ring of guide vanes 70. This avoids localized excessively strong or weak airflow caused by uneven distribution of the guide vanes 70, ensuring globally uniform airflow.
[0153] Each guide vane 70 is designed to rotate around its outer axis, with its free end extending towards the center of the frying basket. This more effectively directs the hot air distributed around the edges of the cooking cavity 201 towards the center of the frying basket 30. By uniformly adjusting the angle of all guide vanes 70, the convergence intensity and coverage of this "centripetal airflow" can be easily controlled. On one hand, rotating food can actively pass through the relatively stable centripetal airflow guided by the guide vanes 70, ensuring that all surfaces of the food come into contact with this optimized airflow. On the other hand, the guiding effect of the guide vanes 70 also allows the hot air to cover the food more continuously, thus forming a more efficient three-dimensional hot air circulation.
[0154] In one possible implementation, please see Figure 12 and Figure 13 As shown, multiple guide vanes 70 can work together to form a spiral airflow structure toward the center region of the blast net 30.
[0155] In this embodiment, the spiral air guide structure allows hot air to rotate around the central axis of the frying net 30 while converging towards the center. This spiral airflow path is longer than a straight path, greatly increasing the residence time and coverage area of the hot air within the cooking cavity 201. It can more effectively penetrate the gaps between stacked food and flow around the food surface, eliminating low-speed or stagnant airflow zones to a greater extent, resulting in a more uniform distribution of hot air within the cooking cavity 201.
[0156] When the spiral airflow direction is the same as the rotation direction of the frying net 30, the relative speed between the food and the airflow can be reduced, resulting in gentler and more uniform heating, which is better suited to delicate ingredients whose surfaces are prone to burning. If the two directions are opposite, the relative speed between the food surface and the airflow can be increased dramatically, effectively enhancing heat exchange efficiency and generating stronger turbulence, allowing the hot air to more violently wash over all surfaces of the food, which is very suitable for ingredients that need to be crisped quickly (such as French fries and fried chicken).
[0157] In one possible implementation, please see Figure 14 As shown, one end of the guide vane 70 is provided with a pivot part 71 that mates with the second pivot shaft 31;
[0158] A damping tooth positioning structure is provided between the second pivot shaft 31 and the pivot part 71 to lock the guide vane 70 at a specified angle.
[0159] The damping tooth positioning structure includes a first damping tooth 311 disposed on the second pivot shaft 31 and a second damping tooth 711 disposed on the guide vane 70. The first damping tooth 311 meshes with the second damping tooth 711 and can self-lock at any swing angle of the guide vane 70.
[0160] In this embodiment, through the gear-like meshing of the first damping tooth 311 and the second damping tooth 711, the guide vane 70 can achieve rigid mechanical locking at each adjustment angle via the meshing surface of the teeth. This locking method can resist the continuous aerodynamic pressure and impact generated by the high-speed hot air during cooking, thereby preventing the guide vane 70 from angularly shifting, shaking, or drifting under the impact of airflow. This ensures that the blade angle set by the user to form a specific airflow pattern (such as spiral airflow) remains constant throughout the cooking process, thus guaranteeing the accuracy, stability, and repeatability of the airflow optimization effect.
[0161] During adjustment, the first damping tooth 311 and the second damping tooth 711 overcome friction to slide relative to each other (usually accompanied by a clear "click" sound, providing operational feedback); when the specified angle is reached and the hand is released, the first damping tooth 311 and the second damping tooth 711 can automatically re-engage and lock. The entire process requires no tools and no additional tightening or unlocking steps, making operation more intuitive and faster, greatly optimizing the convenience of user interaction with the product.
