Description

Technical Field

[0001] This invention relates to the field of cooking equipment technology, and more particularly to a cooking apparatus. Background Technology

[0002] In the field of cooking equipment, the even stirring and stir-frying of ingredients typically relies on the built-in stirring component of the pot. This component simulates manual cooking actions to ensure that the ingredients inside the pot are heated evenly and seasoned thoroughly. However, the pots in existing cooking equipment are mostly of fixed specifications. When the stirring component stirs at high speed, the impact force generated can easily cause the soup inside the pot to splatter, not only contaminating the equipment cavity and the surrounding environment, but also potentially posing safety risks due to the high temperature of the soup. Furthermore, the depth of the pot is usually only sufficient for stir-frying. When dealing with ingredients that require long-term stewing (such as soups or braised dishes), the shallow pot cannot hold enough soup, and the soup is prone to overflowing due to boiling. Therefore, users must replace it with a deeper pot to complete the stewing operation, which makes it difficult to meet the integrated needs of diverse cooking methods.

[0003] In addition, the stirring shaft used for stir-frying is generally connected to the drive mechanism in a non-detachable transmission manner. After the cooking is finished, the user can only disassemble the cooking pot, such as the pot body, for cleaning. When disassembling the cooking pot, since the stirring shaft is generally located inside or above the cooking pot, the cooking pot is restricted by the stirring shaft, which restricts the removal and placement of the pot body and reduces the convenience of use.

[0025] The technical solution of the present invention will be further described below with reference to the embodiments and accompanying drawings.

[0026] See Figures 1 to 6 This invention discloses a cooking device, including a base 10, a cooking pot 20, and a stirring assembly 30. The cooking pot 20 is installed on the base 10. The cooking pot 20 includes a first pot body 21 and a second pot body 22. The first pot body 21 has a first opening 211 and a first locking part 23. The second pot body 22 has a second opening 221 and a second locking part 24. The second pot body 22 is detachably installed on the first pot body 21 and surrounds the periphery of the first pot body 21. After the second pot body 22 is installed on the first pot body 21, it communicates with the first opening 211. When subjected to force, the second locking part 24 moves closer to or away from the first locking part 23, and locks with the first locking part 23 when it is close to the first locking part 23 to lock the second pot body 22. In addition, the mixing assembly 30 includes a mixing element 31, a linkage mechanism 32, and a drive mechanism 33. The mixing element 31 is rotatably mounted on the cooking pot 20, the linkage mechanism 32 is mounted on the base 10, and can move closer to or away from the mixing element 31 under the drive of the drive mechanism 33, and is connected to the mixing element 31 when moving closer to the mixing element 31.

[0027] Based on this structure, during assembly, a connecting structure (such as a connecting seat or bracket) is provided on the side of the first pot body 21 to house the first locking part 23; correspondingly, a matching connecting structure is provided on the outer wall of the second pot body 22 at a position opposite to the first locking part 23 to house the second locking part 24, for example: The second locking part 24 is an elastic buckle structure located at the lower periphery of the second pot body 22, while the first locking part 23 is a matching groove. The end of the elastic buckle has a protrusion that matches the first locking part 23 (groove). When it is necessary to enclose the first pot body 21 with the second pot body 22 to increase the overall depth of the cooking pot 20, the second pot body 22 is placed around the periphery of the first pot body 21. The second pot body 22 is pressed, causing the elastic buckle (i.e., the second locking part 24) to deform under force and move closer to the groove (i.e., the first locking part 23). When the elastic buckle approaches the opening of the groove, it will deform under the combined action of the opening end wall and the second pot body 22, causing the protrusion on the elastic buckle to engage with the groove. Then, the external force is stopped, and the elastic buckle returns to its own deformation and fits tightly against the inner wall of the groove to complete the locking, so that the second pot body 22 and the first pot body 21 are locked. After locking, the second pot body 22 is connected to the first opening 211 on the first pot body 21, making the internal cavity of the entire cookware assembly deeper. When cooking, the user can put the ingredients into the entire cooking pot 20 through the second opening 221. At the same time, the second pot body 22 and the first pot body 21 can be sealed by a sealing structure (such as a rubber or silicone sealing ring) to reduce the probability of juice overflow during cooking. This not only meets the need to hold a large amount of soup when stewing, but also prevents the juice from splashing during cooking by increasing the height of the cavity, reducing pollution and safety hazards.

[0028] When it is necessary to remove the second pot body 22 from the first pot body 21, the user only needs to apply an external force away from the first pot body 21 to the second pot body 22. At this time, the elastic buckle (second locking part 24) will deform again until it is completely disengaged from the slot, and the second pot body 22 can be removed to complete the flexible assembly and disassembly of the first pot body 21 and the second pot body 22.

[0029] Of course, the second locking part 24 can also be movably connected to the second pot body 22 via a spring. In this case, the second locking part 24 can be configured as a columnar structure, elastically assembled with the connecting structure on the second pot body 22 via a compression spring. The spring is sleeved around the outer periphery of the second locking part 24 to provide continuous elastic support force. At the same time, multiple wedge-shaped blocks are provided at the end of the second locking part 24 near the first pot body 21 (one side of the wedge-shaped block is an inclined guide surface, and the other side is a vertical limiting surface). The first locking part 23 is a wedge-shaped groove on the first pot body 21 that matches the second locking part 24 (the inner wall of the groove is provided with an inclined guide surface that matches the wedge-shaped block along the circumferential direction, and the bottom of the groove is provided with an annular limiting step that fits against the vertical limiting surface of the wedge-shaped block).

[0030] In the initial state, when the spring is naturally extended, it drives the second locking part 24 to extend towards the first pot body 21. At this time, the wedge-shaped block at the end of the second locking part 24 is in an unengaged state. When it is necessary to assemble the second pot body 22 with the first pot body 21, the user can press the second locking part 24 towards the first pot body 21 to make the second locking part 24 move towards the first pot body 21 against the spring force. During the movement, the inclined guide surface of the wedge-shaped block on the second locking part 24 slides against the inclined guide surface of the inner wall of the wedge groove (first locking part 23). Under the guidance of the inclined surface, the second locking part 24 produces a slight circumferential rotation. When pressed to the maximum stroke, the wedge-shaped block slides into the bottom of the wedge groove with the rotation and aligns with the annular limiting step in the groove. At this time, the second locking part 24 is released, the spring releases its elastic force to push the second locking part 24 to reset, and the vertical limiting surface of the wedge-shaped block fits tightly against the annular limiting step to form a mechanical lock, realizing a stable lock between the two pot bodies.

[0031] Similarly, when the two pots need to be separated, press the second locking part 24 again to drive the second locking part 24 to move inward again against the spring force. During the movement of the second locking part 24, the inclined guide surface of the wedge block slides and engages with the inclined guide surface of the inner wall of the wedge groove (first locking part 23) again, guiding the second locking part 24 to rotate in the opposite circumferential direction. When the wedge block on the second locking part 24 is aligned with the opening direction of the wedge groove (first locking part 23), the external force of continuing to press makes the wedge block completely disengage from the constraint of the annular limiting step. At this time, release the second locking part 24, the spring pushes the second locking part 24 to reset, and the wedge block extends towards the first pot 21 along with the second locking part 24 as a whole, disengaging from the wedge groove and realizing unlocking.

[0032] Therefore, during the use of this cooking device, when it is necessary to prevent liquid from splashing during stewing or cooking, the second pot body 22 can be locked to the first pot body 21 via the second locking part 24. This locks the first pot body 21 and the second pot body 22 together, so that the second pot body 22 surrounds the opening of the first pot body 21, forming a depth-adjustable combined cavity. This satisfies the volume requirements during stewing and effectively prevents liquid from splashing, reducing the risk of splashing. Similarly, when only simple cooking such as stir-frying is required, applying pressure to the second locking part 24 to disengage it from the first locking part 23 allows the second pot body 22 to be easily detached from the first pot body 21, and the first pot body 21 can be used alone for operation. Through the flexible assembly and disassembly of the two pot bodies, there is no need to replace the entire set of cookware, adapting to different cooking needs and improving ease of use and product versatility.

[0033] In addition, the stirring element 31 can be installed inside the first pot body 21 and connected to the drive mechanism 33 on the base 10 through the linkage mechanism 32. For example, during assembly, a swing arm structure is set at the power output end of the drive mechanism 33. The swing arm structure is connected to the linkage mechanism 32 (such as the linkage shaft (built-in transmission shaft)). When it moves close to the stirring element 31, the power output end of the drive mechanism 33 drives the swing arm structure to swing laterally towards the inside of the cooking pot 20 (in the direction of the stirring element 31). The linkage shaft moves synchronously with the swing arm structure and gradually approaches the stirring element 31 inside the first pot body 21 (the swing trajectory avoids the edge of the pot body to avoid interference).

[0034] It should be noted that a connector 3222b (e.g., a protrusion) can be provided at the end of the linkage shaft, and a matching limiting groove is provided on the top of the stirring component 31, with a spring locking pin inside the groove; when the protrusion is inserted into the groove, the locking pin springs into the positioning hole on the side of the protrusion to complete the mechanical locking, so that the stirring component 31 is not easy to loosen from the linkage mechanism 32 when rotating.

[0035] When stir-frying is required, the rotary drive component 34 (such as an existing servo motor or geared motor) at the other end of the linkage shaft is activated, driving the linkage shaft to rotate through the internal transmission structure (such as a spline or coupling), thereby driving the stirring component 31 to rotate synchronously, thus achieving stir-frying of the ingredients; similarly, when removing the pot, the rotary drive component 34 is de-energized, the linkage shaft and the stirring component 31 stop rotating, the drive mechanism 33 of the swing arm structure drives the swing arm structure to swing laterally to the outside of the pot (away from the stirring component 31), and the linkage shaft returns to its initial position (away from the top of the pot) with the swing arm structure. At this time, the first pot body 21 can be freely removed and placed without structural interference, making it more convenient to use.

[0036] Of course, the linkage mechanism 32 can also be formed by combining a transverse guide rail slider assembly and a linkage shaft. The guide rail is set parallel to the first pot body 21, the slider is slidably mounted on the guide rail, the linkage shaft is connected to the slider, and the drive mechanism 33 (such as an existing micro stepper motor, geared motor, or synchronous motor) is used to drive the slider to move laterally in a straight line along the guide rail towards the pot, so that the linkage shaft moves synchronously with the slider towards the stirring element 31 in the first pot body 21 and is connected to the stirring element 31 for transmission. After locking, the other end of the linkage shaft is connected to the rotary drive element 34, and the torque is transmitted to the connector 3222b through rigid transmission within the shaft (such as a flat key connection), driving the stirring element 31 to rotate and realize the stirring of ingredients.

[0037] Similarly, during disassembly, the rotating drive component 34 stops rotating, and the drive mechanism 33 connected to the slider first outputs a small reverse force, causing the linkage shaft to trigger the unlocking button (mechanical pressing or electromagnetic drive) on the stirring component 31. The spring locking pin retracts into the positioning hole, releasing the lock. The slider moves along the guide rail away from the pot, and the linkage shaft returns to its initial position with the slider, completely detaching from the space above the pot, making it convenient to put away the pot.

[0038] Furthermore, the first pot body 21 is provided with a first handle 25, and the second pot body 22 is provided with a second handle 26. A first locking part 23 is provided on the first handle 25, and a through groove 261 is provided on the second handle 26. The first locking part 23 includes a locking hook 231, and a locking notch 232 is provided on the locking hook 231. The second locking part 24 includes a locking member 241 and an unlocking member 242. The locking member 241 is movably connected to the through groove 261. The locking member 241 includes a force-bearing section 2412 and a locking section 2411. When the force-bearing section 2412 is subjected to force, the locking section 2411 moves closer to or further away from the locking notch 232, and when it is close to the locking notch 232, it engages with the locking notch 232. The unlocking member 242 abuts against the force-bearing section 2412 and presses against the force-bearing section 2412 when subjected to force.

[0039] See Figure 4 , Figure 5Based on this structure, during use, the user can hold the first pot body 21 through the first handle 25 and the second pot body 22 through the second handle 26, facilitating the placement or assembly of the first pot body 21 and the second pot body 22. Simultaneously, the first handle 25 provides a mounting base for installing the locking hook 231, while the through slot 261 of the second handle 26 provides assembly space for the locking member 241 and the unlocking member 242, allowing the first locking part 23 and the second locking part 24 to engage with the gripping components, reducing additional protrusions.

[0040] Specifically, during assembly, the locking hook 231 is installed on the first grip 25, and the opening of the locking notch 232 on the locking hook 231 is set towards the locking section 2411; the locking section 2411 is a rod-shaped or column-shaped structure that can be equipped with a snap-fit ​​structure (such as a barb or a snap-fit ​​connector 2413 or other protruding structure). The end of the locking section 2411 with the snap-fit ​​structure is aligned with the locking notch 232 and is rotatably connected to the second grip 26 through a rotating structure (such as a pin); the force-bearing section 2412 is connected to the end of the locking section 2411 away from the locking hook 231, so that the force-bearing section 2412 can drive the locking section 2411 to rotate when force is applied.

[0041] In the initial state, the locking segment 2411 extends from the bottom of the through groove 261. When it is necessary to fasten the second pot body 22 to the first pot body 21, the unlocking member 242 can be pressed. The unlocking member 242 pushes down on the force-receiving segment 2412. After being subjected to force, the force-receiving segment 2412 rotates downward around the rotating structure. Through the lever principle, it drives the locking segment 2411 to retract upward into the through groove 261. At this time, there is no protrusion at the bottom of the second handle 26, avoiding interference with the first handle 25. Then, the second pot body 22 is aligned and fastened to the first pot body 21. Above the pot body 21, the bottom of the through groove 261 is aligned with the locking hook 231, and the end of the locking section 2411 is aligned with the locking notch 232. Thus, when the unlocking member 242 is released, the force on the force-bearing section 2412 disappears, and the locking member 241 resets under its own weight (or by setting an elastic member). The end with the snap-fit ​​structure rotates downward out of the through groove 261, so that the snap-fit ​​structure engages with the locking notch 232 to form a stable lock, so that the first pot body 21 and the second pot body 22 are stably connected.

[0042] When it is necessary to separate the second pot body 22 from the first pot body 21, press the unlocking part 242 again to press the force-bearing section 2412, and the locking section 2411 will retract upward again to disengage from the locking notch 232. At this time, the second handle 26 can be lifted directly, and the two pot bodies will separate. After releasing the unlocking part 242, the locking section 2411 will return to the extended state and wait for the next locking.

[0043] It should be noted that when installing the unlocking component 242, a pressing notch 262 can be provided on the second grip 26, the pressing notch 262 extends through to the through groove 261, and then the unlocking component 242 is inserted into the through groove 261 through the pressing notch 262 and abuts against the force-bearing section 2412.

[0044] Furthermore, the locking segment 2411 is rotatably connected to the through groove 261, and the force-bearing segment 2412 is inclined from top to bottom in the axial direction of the locking segment 2411 and is connected to the end of the locking segment 2411 away from the locking hook 231; the locking segment 2411 is provided with a snap-fit ​​connector 2413, which snaps into the locking notch 232 and is used to move away from the locking notch 232 when the locking segment 2411 rotates; the through groove 261 is provided with a first elastic element 27, which is used to provide an elastic force to drive the locking segment 2411 to abut against the end wall of the locking notch 232.

[0045] Specifically, such as Figure 5 , Figure 6 As shown, because the force-receiving section 2412 and the locking section 2411 are inclined, the direction of the force on the force-receiving section 2412 (the vertical force of the user pressing the unlocking member 242) and the rotation trajectory of the locking section 2411 (circular motion around the rotating structure) form a suitable angular relationship. Therefore, when the unlocking member 242 is pressed, the inclined force-receiving section 2412 can efficiently convert the vertical pressure into the rotational torque of the locking section 2411. Compared to a vertical connection structure, this allows for driving the locking section 2411 to rotate with less pressing force, effectively reducing the operating effort and improving the user experience.

[0046] More specifically, the snap-fit ​​connector 2413 can be configured as a wedge-shaped protrusion, while the locking notch 232 is a snap-fit ​​structure with the notch facing the snap-fit ​​connector 2413. That is, the upper wall of the locking notch 232 is perpendicular to the locking section 2411, forming a horizontal baffle that fits the snap-fit ​​connector. When the snap-fit ​​connector 2413 moves close to the locking notch 232 and snaps into it, the snap-fit ​​connector 2413 and the upper wall (i.e., the horizontal baffle) of the locking notch 232 are tightly abutted. In other words, the snap-fit ​​connector 2413 hooks onto the upper wall of the locking notch 232, and the upper wall of the locking notch 232 restricts the snap-fit ​​connector 2413 from falling out upwards, thus achieving locking.

[0047] When unlocking, pressing the unlocking component 242 drives the locking section 2411 to rotate upward. The locking connector 2413 rotates around the rotating structure with the locking section 2411 and slides into the opening edge of the locking notch 232 again, so that the locking connector 2413 can smoothly disengage along the opening direction. Unlocking can be completed without applying excessive external force, making the operation labor-saving.

[0048] Meanwhile, in this embodiment, a first elastic element 27 is provided. The first elastic element 27 is assembled vertically below the force-bearing section 2412, and its other end abuts against the bottom wall of the through groove 261. When the snap-fit ​​connector 2413 on the locking section 2411 is engaged into the locking notch 232, the first elastic element 27 is in a pre-compressed state. Through its own elastic deformation, it pushes the force-bearing section 2412 upward, applying a continuous upward elastic force. This elastic force is transmitted to the locking element 241 through the force-bearing section 2412, driving the locking section 2411 to rotate around the rotating structure toward the locking notch 232 by lever principle, so that the snap-fit ​​connector 2413 abuts tightly against the upper wall of the locking notch 232, forming a stable pre-tightening lock.

[0049] When unlocking is required, press the unlocking part 242, and the force-bearing section 2412 moves down by overcoming the elastic force of the first elastic part 27 through external force. During this process, the locking section 2411 moves around the rotating structure in a direction away from the locking notch 232 until the locking connector 2413 disengages from the locking notch 232.

[0050] It should be noted that the first elastic element 27 in this embodiment can be an existing compression spring or elastic column (e.g., silicone column or rubber column) or other elastic structure.

[0051] Alternatively, the snap-fit ​​connector 2413 can be made of a material with elastic deformation capability (such as silicone or elastic plastic) to form an elastic block, whose outer diameter in its natural state is slightly larger than the inner diameter of the locking notch 232. When the snap-fit ​​connector 2413 moves into the locking notch 232 and is inserted, the elastic block is squeezed by the inner wall of the notch and undergoes radial contraction deformation, thus passing through the notch smoothly. After being fully inserted, the elastic block releases its deformation and returns to its original shape, with its outer peripheral wall tightly fitting against the inner wall of the locking notch 232. Through the interference fit and the upper end wall of the locking notch 232, the snap-fit ​​connector 2413 is limited, achieving a stable connection. The continuous elastic tension of the elastic block can also reduce the probability of the snap-fit ​​connector 2413 loosening.

[0052] Furthermore, the cooking pot 20 includes a lid 40, on which a connecting arm 41 and a temperature sensor 42 are provided. The connecting arm 41 is rotatably connected to the base 10 to drive the lid 40 to rotate. The second pot body 22 is connected to the first pot body 21 to form a cooking cavity 201. The lid 40 is used to seal or open the cooking cavity 201 when rotating. The connecting arm 41 is provided with an air duct 411, which has an inlet 4111 and an outlet 4112. The inlet 4111 is connected to the cooking cavity 201. A guide fan is provided at the outlet 4112 to generate negative pressure to guide airflow to the outlet 4112. A temperature sensor 42 is provided at the end of the lid 40 facing the cooking cavity 201 to detect the temperature.

[0053] Specifically, see Figure 7 , Figure 8 and Figure 12 As shown, during cooking, the user can connect one end of the lid 40 to the cooking pot 20 (in this state, the first pot body 21 and the second pot body 22 are locked), and the other end is rotatably connected to the base 10 via the connecting arm 41. The rotation of the connecting arm 41 drives the lid 40 to rotate, thus opening or closing the cooking chamber 201. When the lid 40 is tightly sealed above the cooking chamber 201, a relatively enclosed space is formed inside the cooking chamber 201, reducing the escape path of oil fumes. When cooking food in the cooking chamber 201 produces oil fumes, the user can activate the guide fan, creating a negative pressure inside the air duct 411. Under this negative pressure, the oil fumes inside the cooking chamber 201 have no other diffusion channels and can only be concentrated into the air duct 411 through the inlet 4111. Then, under the continuous driving force of the guide fan, they flow along the air duct 411 to the outlet 4112, and are finally discharged into the external environment through the outlet 4112, achieving directional and efficient emission of oil fumes.

[0054] Since the pot lid 40 remains tightly sealed above the cooking cavity 201 throughout the cooking process, the airtightness of the cooking cavity 201 is maintained. Therefore, under the negative pressure, the oil fumes can only enter the air duct 411 through the inlet 4111, which effectively reduces the problem of oil fumes escaping into the kitchen space during the emission process, reduces the probability of oil fume diffusion, improves the oil fume adsorption efficiency, and makes the oil fume adsorption more thorough.

[0055] In addition, since the lid 40 is also equipped with a temperature sensor 42, such as a thermistor temperature sensor 42, a thermocouple temperature sensor 42, or an infrared probe, if the temperature sensor 42 detects that the temperature inside the cooking cavity 201 is lower than the preset temperature threshold during the oil fume adsorption process, the user or control system can flexibly reduce the airflow of the guide fan according to the real-time temperature signal. By reducing the airflow of the fan, the speed at which heat is lost from the inside of the cooking cavity 201 with the airflow is reduced, thereby reducing the temperature fluctuation of the cooking cavity 201 and ensuring stable cooking temperature. When the temperature sensor 42 detects that the temperature inside the cooking cavity 201 is higher than the preset temperature threshold, the user or control system can increase the airflow of the guide fan. By enhancing airflow, the heat dissipation from the surface of the cooking cavity 201 is accelerated, which helps to regulate the temperature inside the cavity, reduces the risk of food burning due to excessive temperature, and further ensures the stability of the cooking effect.

[0056] It should be noted that in this embodiment, the shape of the lid 40 matches the contour of the cooking cavity 201, so that the lid 40 can completely cover the cooking cavity 201 after being connected to the pot body, thus structurally reducing the escape path of oil fumes. During assembly, the lid 40 is detachably connected to the pot body via the connecting arm 41. Specifically, a rotating connection (such as a hinge connection), a sliding connection, or a snap-fit ​​connection can be selected to meet the usage requirements of the lid 40 for flexible opening and tight sealing.

[0057] In addition, by integrating the air duct 411 into the connecting arm 41, the inlet 4111 of the air duct 411 is set on the pot lid 40, while the outlet 4112 extends to the outside of the base 10, so that the oil fumes inside the cooking cavity 201 can be introduced into the air duct 411 in the connecting arm 41, and then flow to the outlet 4112 and be discharged to the outside through the exhaust port 12. This not only reduces the problem of occupying extra space by setting up the air duct 411 separately, but also uses the connecting arm 41 to realize the dual functions of rotating connection between the pot lid 40 and the base 10 and airflow conduction, so that the oil fume guide path is relatively sealed throughout, further improving the oil fume adsorption efficiency.

[0058] It should be noted that the connecting arm 41 in this embodiment can adopt a hollow structure, so that a cavity for fluid flow is formed inside to form the above-mentioned air duct 411; of course, it can also be formed by setting a pipe or a shell with a hollow structure inside the connecting arm 41, so that an air duct 411 is formed inside, depending on the actual needs; in addition, the connecting arm 41 can adopt a hinge or shaft or other rotating structure to achieve a rotating connection with the base 10.

[0059] More specifically, the guide fan can be an existing centrifugal fan, axial fan or cross-flow fan, etc., installed at the outlet 4112 to draw in the oil fumes inside the duct 411 and guide them to flow to the outlet 4112 for discharge. The specific selection can be matched according to the diameter of the duct 411 and the oil fume discharge requirements, ensuring that the negative pressure intensity and smoke exhaust efficiency are compatible.

[0060] Furthermore, a humidity sensor 43 is provided at the end of the lid 40 facing the cooking cavity 201. During assembly, the detection end of the humidity sensor 43 is set facing the inside of the cooking cavity. The humidity sensor 43 monitors the changes in air humidity inside the cooking cavity 201 and transmits the humidity data to the cookware control system or provides feedback to the user in real time.

[0061] Specifically, if the humidity inside the cooking cavity 201 is too high, the water vapor in the fumes will easily condense into liquid oil droplets on the inner wall of the air duct 411. Long-term accumulation may cause the air duct 411 to become blocked and affect the smoke exhaust efficiency. Therefore, when the humidity sensor 43 detects high humidity, it can feed the humidity data back to the background control system or the user. At this time, the user or the background control system can increase the airflow of the guide fan, speed up the airflow, and reduce the residence time of water vapor in the air duct 411 to reduce the problem of oil droplet condensation.

[0062] Furthermore, during the initial stages of cooking (such as after the ingredients are added to the pot), moisture inside the cavity evaporates rapidly, and humidity and oil fume levels rise simultaneously. At this time, the user or the back-end control system can adjust the fan speed based on the humidity data to enhance oil fume extraction. Conversely, during the later stages of cooking (such as the sauce reduction stage), humidity decreases and oil fume levels decrease, allowing the user to simultaneously reduce the fan speed, balancing smoke extraction efficiency with energy conservation needs, and further reducing temperature fluctuations. It should be noted that the humidity sensor 43 can be any existing humidity detection device, such as a capacitive humidity sensor 43 or a resistive humidity sensor 43.

[0063] Furthermore, the base 10 is provided with an exhaust port 12; the connecting arm 41 is provided with an air duct 412, and the air channel 411 is located in the air duct 412; the air duct 412 includes a first pipe section 4121 and a second pipe section 4122, the first pipe section 4121 is installed on the connecting arm 41, one end of the second pipe section 4122 is connected to and communicates with the first pipe section 4121, and the other end of the second pipe section 4122 passes through the base 10 and communicates with the exhaust port 12; a filter element 13 is provided at the exhaust port 12, and the filter element 13 is used for filtration.

[0064] Specifically, such as Figure 7 , Figure 8 As shown, during assembly, an air duct 412 is installed inside the connecting arm 41. The first section 4121 of the air duct 412 extends above the pot lid 40 and is connected to the cooking cavity 201. The other end of the first section 4121 is connected to one end of the second section 4122, and the other end of the second section 4122 extends to the exhaust port 12 of the base 10. The splicing of the two first sections 4121 and the second section 4122 forms a complete and independent air duct 411. By utilizing the smooth characteristics of the inner wall of the air duct 412 and the arc transition structure at the pipe connection, the local resistance during the airflow process can be effectively reduced, making the airflow conduction smoother, thereby improving the overall airflow conduction efficiency.

[0065] It should be noted that the first pipe section 4121 and the second pipe section 4122 can be made of existing metal or plastic pipes with a hollow internal structure, and the internal cavity dimensions of the first pipe section 4121 and the connecting arm 41 are matched. During assembly, a rubber seal or silicone seal can be added between the first pipe section 4121 and the second pipe section 4122, and then fastened with clamps (hose clamps), flanges or clamps to achieve a sealed connection. Of course, the two can also be connected by welding or gluing, depending on the actual needs.

[0066] In addition, a filter element 13 is provided at the exhaust port 12. The filter element 13 is used for filtration. In this way, when the oil fumes inside the air duct 411 flow to the exhaust port 12 under the action of the guide fan, they will first flow through the filter element 13 at the exhaust port 12. At this time, the oil particles and some odor substances in the oil fumes can be intercepted and purified by the filter element 13. Finally, the purified airflow is discharged to the external environment through the exhaust port 12, thereby reducing the problem of oil fumes being directly discharged into the external environment and polluting the surrounding air quality.

[0067] It should be noted that the filter element 13 in this embodiment can adopt existing metal filter screen, activated carbon filter screen, HEPA filter screen or composite filter material (such as a combination of metal filter screen and activated carbon layer) and other filter structures. It can be assembled with the exhaust port 12 by snap-on, plug-in or threaded connection, and the filter pore size and material of the filter element 13 can be adapted and selected according to the filtration requirements of oil particles and volatile organic compounds in the oil fume.

[0068] More specifically, the lid 40 is provided with a vent 45 that penetrates the lid 40. Excess steam inside the cooking cavity 201 is discharged in time through the vent 45, thereby reducing the risk of excessive pressure inside the pot, reducing the risk of the lid 40 being lifted and soup overflowing, and reducing safety hazards.

[0069] Furthermore, the cooking device includes an anti-rotation assembly 50, which includes a first anti-rotation member 51, a second anti-rotation member 52, and a second elastic member 53. The connecting arm 41 is rotatably connected to the base 10 via a rotating shaft 14. The first anti-rotation member 51 is connected to the rotating shaft 14 and is used to rotate along with the rotating shaft 14 when it rotates. The second anti-rotation member 52 is used to cooperate with the first anti-rotation member 51 to prevent rotation when rotating, so as to limit the rotation of the rotating shaft 14. The second elastic member 53 is used to provide an elastic stress acting on the first anti-rotation member 51 or the second anti-rotation member 52.

[0070] Based on the above structure, during installation, an installation cavity can be set inside the base 10, and the anti-rotation component 50 can be installed in the installation cavity. The first anti-rotation component 51 can be a gear structure, with a keyway or hole in its center that matches the rotating shaft 14. It is fixedly connected to the rotating shaft 14 by means of interference fit, key connection, etc., so that when the rotating shaft 14 rotates, it can synchronously drive the first anti-rotation component 51 to rotate coaxially. The second anti-rotation component 52 also adopts a gear structure. During installation, the second anti-rotation component 52 can be rotatably installed inside the base 10 through the support shaft and mesh with the first anti-rotation component 51 for transmission. One end of the second elastic element 53 (such as a tension spring) is connected to the fixed point of the base 10 by means of hooks, bolts, etc., and the other end is connected to the eccentric position (non-rotation center) of the driven gear. After assembly, the second elastic element 53 is always in a stretched state, that is, it continuously applies an elastic tension along the stretching direction to the driven gear.

[0071] The following explanation uses the first anti-rotation member 51 as the driving wheel and the second anti-rotation member 52 as the driven wheel as an example: When the user needs to open the pot lid 40, an outward flipping force is applied to the pot lid 40. This force is transmitted to the rotating shaft 14 through the connecting arm 41, driving the rotating shaft 14 to rotate counterclockwise (viewed from a top view). Since the driving gear (first anti-rotation member 51) is fixedly connected to the rotating shaft 14, the driving gear can rotate counterclockwise synchronously with the rotating shaft 14. During this process, based on the transmission characteristics of gear meshing, the driven gear (second anti-rotation member 52) meshing with the driving gear will be subjected to the meshing force of the driving gear teeth. The direction of this meshing force is opposite to the rotation direction of the driving gear. Therefore, the driven gear rotates clockwise under the action of the meshing force.

[0072] Meanwhile, the second elastic element 53 is always in a stretched state, and the direction of the elastic tension it applies to the driven gear (second anti-rotation element 52) ​​remains unchanged. Since the second elastic element 53 is connected to the eccentric position of the driven gear, this tension will generate a clockwise torque (i.e., driving torque) on the rotation center of the second anti-rotation element 52 (driven gear), driving the driven gear to rotate clockwise. The clockwise rotation tendency of the driven gear will react on the driving gear through gear meshing, forming a counterclockwise resistance torque on the driving gear (opposite to the rotation direction of the shaft 14). As the opening angle of the lid 40 increases, the angle at which the rotating shaft 14 drives the drive gear to rotate counterclockwise also increases, and the angle at which the drive gear rotates clockwise also increases. The stretching length of the second elastic element 53 further increases, and the elastic tension it generates increases synchronously, thereby gradually increasing the resistance torque acting on the drive gear. When the user stops applying the opening force, the rotational power of the rotating shaft 14 disappears. At this time, the drive gear is only subjected to the resistance torque transmitted by the driven gear, while the driven gear is subjected to the driving torque of the second elastic element 53 and the meshing resistance torque of the drive gear. The two form a mutually restrictive force balance state. The resistance torque of the second elastic element 53 applied to the drive gear of the first anti-rotation element 51 through the driven gear cancels out the gravity of the rotating shaft 14 and the lid 40 itself, ultimately causing the rotating shaft 14 to stop rotating at the current rotation angle, achieving a hovering effect.

[0073] It should be noted that as the opening angle of the lid 40 gradually increases, the center of gravity of the lid 40 gradually approaches the rotation center of the rotating shaft 14, and the overturning torque generated by the weight of the lid 40 gradually decreases. At the same time, the stretching length of the second elastic element 53 gradually shortens, and the elastic tension and resistance torque generated by it also gradually decrease. The resistance torque decreases adaptively with the increase of the opening angle, and always maintains a dynamic match with the gradually decreasing gravity torque of the lid 40.

[0074] As the rotation angle of the lid 40 gradually approaches a state parallel to that of the cooking pot 20, the gravitational torque of the lid 40 has decreased to a smaller value. At this time, the tension of the second elastic element 53 also decreases synchronously, and can still form a new force balance with the gravitational rectangle of the lid 40, thus achieving reliable suspension even at a larger opening angle.

[0075] That is, during the entire opening stroke of the lid 40, the resistance torque provided by the second elastic element 53 gradually decreases as the opening angle increases, which is compatible with the changing trend of the lid 40's own gravitational torque. The two can form a mutually restrictive force balance at any angle, ultimately causing the rotating shaft 14 and the lid 40 to stop rotating at the current rotation angle, thus achieving stepless hovering.

[0076] In this way, when the lid 40 is rotated to the specified angle by the connecting arm 41, it can be stably maintained at the opening angle as long as the external force is stopped. The user does not need to continuously hold the lid 40 with their hands, which reduces the probability of the lid 40 falling back and hitting the pot body due to gravity after it is fully opened, making it safer to use.

[0077] When the user needs to close the lid 40, they only need to apply an inward pressing and flipping force to the lid 40. This force drives the rotating shaft 14 to rotate clockwise, and the first anti-rotation member 51 (driving gear) rotates clockwise in sync. Through gear meshing, it drives the second anti-rotation member 52 (driven gear) to rotate counterclockwise. At this time, the stretching length of the second elastic member gradually decreases, and the elastic tension and resistance torque weaken synchronously. The balance of forces is broken, and the lid 40 can smoothly rotate to the sealing position to complete the closure.

[0078] Preferably, in this embodiment, the base 10 is provided with a sliding assembly, which includes a slider and a slide rail. The slider is elastically connected to the base 10 through a second elastic element. The slide rail extends along a first direction and slides in cooperation with the slider. The first anti-rotation member 51 includes a first gear 511 and an anti-rotation structure 512. The first gear 511 is connected to the rotating shaft 14 and rotates accordingly. The anti-rotation structure 512 is used to provide a top pressure to limit the rotation of the first gear 511. The second anti-rotation member 52 includes a second gear 521, a cam 522 and a rocker arm 523. During assembly, the second gear 521 meshes with the first gear 511. One end of the cam 522 is connected to the second gear 521, and the other end of the cam 522 is connected to one end of the rocker arm 523. The other end of the rocker arm 523 is connected to the slider.

[0079] Specifically, during installation, the second elastic element is in a stretched state, with one end fixed to the base 10 and the other end connected to the slider. It continuously applies a pulling force along the first direction (vertically downward) to the slider, causing the slider to always have a downward sliding tendency. The working action of the swing arm 523 and the cam 522 pulls the eccentric point of the second gear 521 downward, forcing the second gear 521 to maintain a clockwise rotation tendency. Meanwhile, the anti-rotation structure 512 contacts the teeth of the first gear 511411, applying a continuous reverse upward pressure to the first gear 511. This, combined with the clockwise restraining force transmitted by the second elastic element, double restricts the rotation of the first gear 511, so that the pot lid 40 is tightly closed in the initial state. When the pot lid 40 needs to be opened, the user applies an outward flipping force to the pot lid 40, driving the rotating shaft 14 to rotate counterclockwise. The first gear 511 rotates counterclockwise synchronously with the rotating shaft 14. At the same time, the first gear 511 transmits a counterclockwise meshing force to the second gear 521 through gear tooth meshing. The direction of this meshing force is opposite to the initial clockwise rotation trend of the second gear 521, and it needs to overcome the clockwise torque applied to the second gear 521 by the second elastic element through the linkage structure.

[0080] When the counterclockwise meshing force transmitted by the first gear 511 is greater than the clockwise pulling torque of the second elastic element, the second gear 521 begins to rotate counterclockwise. As the second gear 521 rotates counterclockwise, the cam 522, which is fixed to the second gear 521, rotates counterclockwise synchronously with it. At the same time, the slider, under the pulling force of the second elastic element, always has a tendency to slide vertically downward, driving the swing arm 523 to move downward. This causes the swing arm 523 to apply a downward pulling force to the cam 522, forcing the cam 522 to have a tendency to rotate downward (clockwise). The counterclockwise rotation of the cam 522 with the second gear 521 and the downward pulling tendency of the swing arm 523 form a counter-restraint. When the user stops applying force, the first gear 511 loses its driving force. At this time, the clockwise counter-meshing force transmitted by the second gear 521 and the top pressure of the anti-rotation structure 512 work together to counteract the counterclockwise torque generated by the weight of the pot lid 40, so that the pot lid 40 is stably suspended in the designated position.

[0081] When the lid 40 needs to be closed again, the user only needs to apply an inward pressing and flipping force to the lid 40 to overcome the top pressure of the anti-rotation structure 512, so that the rotating shaft 14 rotates in a clockwise direction. The first gear 511 rotates clockwise synchronously with the rotating shaft 14, and transmits a clockwise meshing force to the second gear 521 through gear tooth meshing. The direction of this meshing force is consistent with the initial clockwise rotation trend of the second gear 521, and is superimposed with the clockwise pulling force applied by the second elastic through the cam 522 and the swing arm 523. There is no need to overcome the reverse torque, reducing the closing force required by the user.

[0082] Under the action of superimposed force, the second gear 521 rotates rapidly in the clockwise direction, and its eccentric point gradually moves from the high position when the cover is opened to the low position. Through the connecting rod, it pushes the slider to slide vertically downward along the slide rail. As the slider moves down, the tensile length of the second elastic element gradually decreases, the deformation decreases, and the downward pulling force weakens simultaneously. When the slider slides to the bottom of the slide rail, the second elastic element returns to the initial tensile state, the pulling force returns to the initial value, the slider stops moving, and the linkage structure also returns to the initial position.

[0083] When the lid 40 completely seals the opening of the pot, the user stops applying the closing force. At this time, the second elastic element remains in its initial state and continues to apply a clockwise torque to the second gear 521 through the slider and linkage structure. This causes the second gear 521 to transmit a clockwise restraining force to the first gear 511 through meshing. This restraining force works in conjunction with the reverse top pressure of the anti-rotation structure 512 to double restrict the rotation of the first gear 511, making the lid 40 fit tightly against the pot.

[0084] It should be noted that, in this embodiment, when the cam 522 is installed, one end can be fixed to the end face of the second gear 521 by key connection or welding (rotating coaxially with the second gear 521), and the other end edge is provided with a cylindrical connecting shaft; one end of the rocker arm 523 is hinged to the connecting shaft on the cam 522, so that it can rotate relative to the cam 522, and the other end is connected to the slider by a pin.

[0085] Furthermore, the linkage mechanism 32 includes a rocker arm 321 and a movable sleeve 322. The rocker arm 321 has a first end and a second end. The first end is provided with a first groove 3211, and the second end is connected to the drive mechanism 33. The movable sleeve 322 includes a first moving rod 3221 and a second moving rod 3222. One end of the second moving rod 3222 is inserted into the interior of the first moving rod 3221, and the other end of the second moving rod 3222 extends at least partially out of the first moving rod 3221 and is used to drive the stirring component 31. The first moving rod 3221 is provided with a first pin 323 and a second pin 324. The first pin 323 is slidably connected to the first groove 3211. The second moving rod 3222 is drively connected to the first moving rod 3221 through the second pin 324.

[0086] Based on the above structure, see [link / reference] Figures 14 to 16 As shown, in the initial state, the swing rod 321 is in a horizontal or initial position away from the cookware, the first moving rod 3221 is at the farthest end away from the stirring element 31, and the second moving rod 3222 is partially retracted within the first moving rod 3221. When it is necessary to connect with the stirring element 31, the drive mechanism 33 drives the swing rod 321 to swing in the direction of the cooking cookware 20 (towards the stirring element 31). The first groove 3211 at the first end of the swing rod 321 pushes the first moving rod 3221 to move laterally in the direction of the stirring element 31 through the first pin 323.

[0087] When the first moving rod 3221 moves, it drives the second moving rod 3222 to move synchronously towards the stirring component 31 via the second pin 324. If the end of the second moving rod 3222 does not contact the stirring component 31, it will continue to advance with the first moving rod 3221. If the end contacts the stirring component 31 first, the second moving rod 3222 will be blocked by the stirring component 31 and stop axial advancement. At this time, the first moving rod 3221 continues to move towards the stirring component 31, and the second moving rod 3222 retracts relative to the first moving rod 3221 (increasing the nesting depth) until the swing rod 321 swings to the preset angle. The second moving rod 3222 then connects with the stirring component 31 through the end connector 3222b (such as a snap-fit ​​or magnetic structure).

[0088] Similarly, when it is necessary to separate from the stirring element 31, the drive mechanism 33 drives the swing arm 321 to swing away from the cooking pot 20 in the opposite direction. The first groove 3211 at the first end of the swing arm 321 pulls the first moving rod 3221 to move laterally away from the stirring element 31 through the first pin 323. When the first moving rod 3221 moves, it drives the second moving rod 3222 to move away from the stirring element 31 in sync through the second pin 324. If the second moving rod 3222 is in a retracted state, it will gradually extend out of the first moving rod 3221 as the first moving rod 3221 is pulled, until the swing arm 321 returns to the initial position, and the second moving rod 3222 completely separates from the stirring element 31 and returns to the position away from the stirring element.

[0089] It should be noted that the extension and retraction stroke of the second moving rod 3222 must match the swing angle of the swing rod 321 and the groove length of the first sliding groove 3211, so that when the swing rod 321 swings to the maximum angle, the second moving rod 3222 can extend to a sufficient length to connect with the stirring piece 31; when the swing rod 321 returns to its original position, the second moving rod 3222 can be fully retracted or extended to a safe distance without affecting the loading and unloading of the cookware.

[0090] Furthermore, the first moving rod 3221 has a through cavity 3212b inside, and the second moving rod 3222 passes through the through cavity 3212b and slides with the first moving rod 3221; the second moving rod 3222 has a second groove 3222a on one end of the through cavity 3212b, and the second pin 324 cooperates with the second groove 3222a to make the second pin 324 slide connected with the second moving rod 3222.

[0091] Based on this structure, the through-hole 3212b is a cylindrical or square cavity, serving as a guide channel for the extension and retraction of the second moving rod 3222. A first pin 323 is fixed to the outer wall (fitting with the first groove 3211 of the swing rod 321), and a second pin 324 is fixed to the inner wall (transversely penetrating the through-hole 3212b and fitting with the second groove 3222a of the second moving rod 3222). The rod body of the second moving rod 3222 has a clearance fit with the through-hole 3212b (allowing only axial sliding). A second groove 3222a (e.g., an elongated slot along the axial direction of the rod body) is opened at one end of the through-hole 3212b. The second pin 324 passes through this slot, restricting the circumferential rotation of the second moving rod 3222 relative to the first moving rod 3221, but allowing axial extension and retraction.

[0092] Specifically, when it is necessary to move closer to the stirring component 31, the drive mechanism 33 drives the rocker arm 321 to swing in the direction of the stirring component 31 (assuming clockwise), and the first groove 3211 at the first end of the rocker arm 321 moves in an arc shape with the rocker arm 321. At this time, the first pin 323 on the first moving rod 3221 is embedded in the first groove 3211. Because the first moving rod 3221 is constrained by the X-axis (such as the horizontal direction of the cooking pot 20) and cannot move in an arc with the groove, the inner wall of the first groove 3211 will generate a thrust on the first pin 323 in the positive direction of the X-axis (close to the stirring member 31). The first pin 323 transmits the thrust to the first moving rod 3221, causing it to move linearly in the positive direction of the X-axis. The second pin 324 in the through cavity 3212b moves synchronously with the first moving rod 3221 toward the stirring member 31, thereby causing the second moving rod 3222 to move synchronously with the first moving rod 3221 until it contacts the stirring member 31.

[0093] Since the second moving rod 3222 is driven by the second pin 324 to move synchronously in the positive X-axis direction because the second pin 324 passes through its second slide groove 3222a (at this time, the position of the second pin 324 in the second slide groove 3222a remains unchanged, and there is no relative sliding between the two), the rod body extends from the through cavity 3212b toward the stirring member 31, and the end gradually approaches the stirring member 31. When the end of the second moving rod 3222 contacts the stirring member 31 (or reaches the preset docking position), its axial movement is blocked.

[0094] However, at this time, the swing rod 321 is still swinging. The first moving rod 3221 continues to move in the positive X-axis direction under the push of the first pin 323, which causes the second pin 324 in the through cavity 3212b to be displaced in the positive X-axis direction relative to the second moving rod 3222. The second pin 324 slides along the second groove 3222a (axial slot) of the second moving rod 3222 towards the end of the slot. The second moving rod 3222 retracts into the through cavity 3212b relative to the first moving rod 3221 (nesting depth increases) until the swing rod 321 swings to the maximum angle. At this time, the end of the second moving rod 3222 is connected with the stirring component 31, and the second pin 324 just abuts against the end of the second groove 3222a to achieve locking.

[0095] Similarly, when it is necessary to move away from the stirring component 31, the first pin 323 generates a pulling force in the negative X-axis direction (away from the stirring component 31), the first moving rod 3221 moves linearly in the negative X-axis direction, and the second pin 324 in the through cavity 3212b retracts synchronously. The second pin 324 pulls the second moving rod 3222 away synchronously. During the retraction process, the second pin 324 first contacts the end of the second slide groove 3222a (releasing the rigid lock during docking), and then drives the second moving rod 3222 to move synchronously in the negative X-axis direction (at this time, the position of the second pin 324 in the second slide groove 3222a remains unchanged), and the end of the second moving rod 3222 separates from the stirring component 31.

[0096] It should be noted that if the second moving rod 3222 is in a retracted state when it approaches, when the first moving rod 3221 continues to retract to the limit position of the through cavity 3212b, the second pin 324 will slide along the second slide groove 3222a towards the starting end of the slot. The second moving rod 3222 will extend out of the through cavity 3212b under its own weight or the action of the return spring (optional) and return to its initial length. Finally, the swing rod 321 will return to its initial angle, and the second moving rod 3222 will be completely away from the stirring component 31, without affecting the loading and unloading of the pot.

[0097] Thus, the transformation from arc motion to linear motion is achieved through the linkage of the first slide groove 3211, the first pin 323 and the swing rod 321. Furthermore, the length reservation of the second slide groove 3222a compensates for the difference in the stroke between the first moving rod 3221 and the second moving rod 3222, so that the two do not interfere with each other during the linkage process.

[0098] It should be noted that, in this embodiment, the second groove 3222a can be configured as an elongated slot along the axial direction. The second pin 324 fits against the two side walls of the slot, preventing the second moving rod 3222 from rotating relative to the first moving rod 3221 around the axial direction (circumferential limitation). When the linkage mechanism 32 needs to drive the stirring component 31 to rotate, the rotational torque received by the first moving rod 3221 will be transmitted to the second moving rod 3222 through the second pin 324 (because there is no relative sliding in the circumferential direction), and then the second moving rod 3222 will drive the stirring component 31 to rotate synchronously, so that the power transmission is lossless. This achieves the axial extension and retraction of the second moving rod 3222 while reducing its circumferential rotation problem, taking into account both motion flexibility and transmission reliability.

[0099] Furthermore, based on the structure of the above embodiments, refer to Figure 14. Figure 15 and Figure 16 As shown, in this embodiment, the rotary drive 34 is connected to the first moving rod 3221 via a transmission mechanism 35. The transmission mechanism 35 specifically includes a driving gear 351 and a driven gear 352. The driving gear 351 is connected to the output end of the rotary drive 34, and the driven gear 352 meshes with the driving gear 351 to achieve power transmission.

[0100] The driven gear 352 and the first moving rod 3221 are connected by a sliding and circumferentially limiting fit. Specifically, the shaft hole of the driven gear 352 is a non-circular hole, such as a square hole, a flat oval hole, or a polygonal hole; the end of the first moving rod 3221 that mates with the driven gear 352 is configured with a flat, square, or polygonal structure adapted to the aforementioned non-circular hole (see [reference]). Figure 15 The first moving rod 3221 is slidably fitted into the non-circular shaft hole of the driven gear 352. The two are mutually limited in the circumferential direction and can slide relative to each other in the axial or radial direction.

[0101] With this configuration, when the first moving rod 3221 swings laterally under the drive of the swing rod 321, the first moving rod 3221 can slide relative to the shaft hole of the driven gear 352, thereby achieving free swinging and not being constrained or jammed by the driven gear 352. When the rotary drive 34 drives the driven gear 352 to rotate through the drive gear 351, due to the circumferential limiting fit between the driven gear 352 and the first moving rod 3221, the driven gear 352 can circumferentially press against the side wall of the non-circular hole and drive the first moving rod 3221 to rotate synchronously, thereby transmitting the rotational power to the first moving rod 3221.

[0102] With the above structure, the first moving rod 3221 can both swing laterally and rotate synchronously with the driven gear 352, and the two movements are independent of each other and do not interfere with each other.

[0103] Furthermore, the cooking device includes a seasoning assembly 60, which is mounted on the base 10. The seasoning assembly 60 includes a seasoning box 61, a feeding tube 62, and an on / off switch 63. One end of the feeding tube 62 is connected to the seasoning box 61, and the other end of the feeding tube 62 is connected to the cooking pot 20. The on / off switch 63 is used to lock or release the feeding tube 62.

[0104] For example, the feeding tube 62 can be a rubber hose, silicone hose, or PP plastic hose. The feeding tube 62 is tubular, and its first and second ends form a liquid outlet channel connecting the seasoning box 61 and the cooking pot 20. Because the feeding tube 62 has a certain degree of flexibility and resilience, it deforms when subjected to external force and rebounds when not subjected to external force, thereby realizing the opening and closing of the liquid outlet channel formed by the feeding tube 62.

[0105] Specifically, the on / off switch 63 can be set outside the feeding pipe 62. The on / off switch 63 does not directly contact the seasoning inside the feeding pipe 62, reducing contamination and extending service life. When the on / off switch 63 is closed, it squeezes the feeding pipe 62 to deform, thereby closing the liquid outlet channel formed by the feeding pipe 62. When the on / off switch 63 is opened, it moves away from the feeding pipe 62, thereby opening the liquid outlet channel formed by the feeding pipe 62, which is easy to operate.

[0106] More specifically, the on / off switch 63 includes a mounting box 631, a slider, and a power source 634. The mounting box 631 has a first linear slide groove inside. The power source 634 is located at the initial end of the first linear slide groove. The mounting box 631 has a limit structure at the end of the first linear slide groove. The slider is slidably connected to the first linear slide groove. The feeding tube 62 is located between the limit structure and the slider. Driven by the power source 634, the slider slides along the first linear slide groove between the initial end and the end of the first linear slide groove.

[0107] For example, see Figure 19 as well as Figure 20 The first linear slide is set in the transverse direction, with the initial end of the first linear slide located on the right side and the end of the first linear slide located on the left side.

[0108] Power source 634 drives slider to move to the left along the first straight groove and approach the limiting protrusion 632. The slider presses the feeding tube 62 against the limiting protrusion 632, thereby compressing and deforming the feeding tube 62, and thus closing the liquid outlet channel formed by the feeding tube 62. Power source 634 drives slider to move to the right along the first straight groove and away from the limiting protrusion 632. The slider moves away from the feeding tube 62, thereby resetting the feeding tube 62, and thus opening the liquid outlet channel formed by the feeding tube 62.

[0109] In addition, a clamping structure 633 (e.g., a protrusion) can be synchronously set on the slider so that when the slider moves close to the limiting protrusion 632, the pressure is more concentrated on the feeding tube 62 through the limiting protrusion 632 and the protrusion on the clamping structure 633, and the clamping is tighter.

[0110] It should be noted that the seasoning box 61 can be a seasoning jar, seasoning bottle or other structure, as long as it can store liquid seasonings according to the actual application; while the power source 634 can be an existing cylinder or hydraulic cylinder.

[0111] Furthermore, in this embodiment, the pot lid is equipped with a feed guide hole 44 and a liquid inlet connector 46. During assembly, the liquid inlet connector is installed inside the connecting arm and communicates with the feed guide hole 44. Then, the end of the feeding pipe 62 away from the seasoning box 61 is extended into the machine base and extends from inside the machine base into the connecting arm to connect and communicate with the liquid inlet connector. This ensures that the feeding pipe 62 is protected by the connecting arm and the outer shell of the machine base, making it less prone to damage. At the same time, when the pot lid is covering the cooking cavity, the seasoning can be directly discharged into the cooking cavity through the feed guide hole, making the operation more convenient.

[0112] More specifically, this embodiment also includes a suction pump 70, which is connected to a feeding pipe to provide power so that the seasoning liquid in the feeding pipe can be automatically introduced into the cooking cavity.

It should be noted that those skilled in the art can make various improvements and modifications without departing from the principles of this invention, and these improvements and modifications are also considered within the scope of protection of this invention.
