Description

Technical Field

[0001] The present invention relates to the field of cooking equipment, and in particular to a cooking equipment. Background Art

[0002] As people's living standards improve, the requirements for food cooking methods are becoming more and more diverse. In order to simplify the number of cooking devices, the method of setting multiple cooking functions on a cooking device has become more and more popular. For example, according to the structure of the traditional air fryer, the mechanism controlling the fryer is rotated, and then the frying pan can be used to achieve the frying function, and the boiling function can be achieved when it is used with a cooking pot. For example, the flip-top multifunctional air fryer disclosed in CN114468795A requires more space when switching between the two cooking modes, which is not convenient for users to use.

[0003] Existing air fryers can be flipped in place to switch between air frying and frying modes. However, when the head of an existing flip air fryer is flipped from air frying mode to frying mode, if the head is not supported deliberately, the head part will fall freely at a high speed and with a large impact force, thereby reducing the life of its internal structure and affecting the user experience. In addition, when users flip the head in air frying mode, they are easily confused about the flipping direction. The wrong flipping direction can easily cause users to touch the heating tube inside the head during operation, causing burns. Summary of the invention

[0004] In view of the shortcomings of the prior art, the purpose of the present invention is to provide a cooking device to solve the problems of the head falling too fast during the flipping process and the flipping direction being difficult to identify.

When the head is in the second working position, the reset member is in a relaxed state. When the head is flipped from the second working position to the first working position, the reset member is squeezed and transitions from a relaxed state to a compressed state. When the head exits the second working position, the reset member changes from a compressed state to a relaxed state, thereby driving the head to automatically rotate a certain angle to indicate to the user the flipping direction when the head switches from the first working position to the second working position, thereby reducing the probability of burns caused by the user using the wrong flipping direction.

There is at least one time period T1 in the process of rotating from the first working position to the second working position. During the time period T1, the buffer structure generates a friction force between the handpiece 400 and the main body 100 to prevent the handpiece 400 from rotating. There is at least a partial time period T2 in this time period T1, and the friction torque during the time period T2 is greater than the gravity torque of the handpiece 400, so that the rotation speed of the handpiece 400 is reduced to zero when the handpiece 400 reaches the second working position or before.

[0119] Theoretically, if the projection of the center of gravity of the head 400 on the horizontal plane is located at the projection of the axis of rotation on the horizontal plane, the head 400 will be unlocked in the first working position and the second working position, and the center of gravity of the head 400 will not deflect, and will not flip and fall quickly. However, in the actual assembly process, due to factors such as part errors and assembly errors, it is difficult to ensure that the projection of the center of gravity of the head 400 on the horizontal plane is located at the projection of the axis of rotation on the horizontal plane. The head 400 will fall quickly under the influence of gravity after being unlocked, and after rotating into place, the head 400 will continue to shake for a period of time due to the non-zero rotation speed. The rapid fall and shaking of the head 400 will impact the base 101, causing the connection between the head 400 and the base 101 to be subjected to a large pulling force, and the parts at the connection are easily loosened and damaged, resulting in a poor user experience. In response to the above problem, the present embodiment provides a buffer structure, which creates friction between the head 400 and the main body 100. The friction is used to reduce the gravity when the head 400 rotates and falls, so that the head 400 falls slowly during the rotation process, preventing the head 400 from rotating and falling quickly to impact the base, and preventing the head 400 from continuing to shake after it is rotated into place.

[0120] The main body 100 further includes a support mechanism, the support mechanism is connected to the base 101, and the head 400 is rotatably connected to the support mechanism. The head 400 has a head docking side facing the support mechanism, and the support mechanism has a support mechanism docking side facing the head 400, the head docking side is opposite to the support mechanism docking side, and the head docking side or the support structure docking side is provided with a rotating shaft, and the head 400 is rotatably connected to the support mechanism through the rotating shaft.

[0121] See also Figure 1-Figure 4, the support mechanism includes a first support member 102 and a second support member 103, and the first support member 102 and the second support member 103 are respectively connected to the two sides of the base 101. The head 400 includes a head housing 403, and the rotating shaft includes a first rotating shaft 404 and a second rotating shaft 405, the first rotating shaft 404 is arranged on the first side of the head housing 403, and the second rotating shaft 405 is arranged on the second side of the head housing 403. The first rotating shaft 404 is rotatably connected to the first support member 102, and the second rotating shaft 405 is rotatably connected to the second support member 103. The first side and the second side of the cooking device are both provided with a head docking side and a support mechanism docking side. The head docking side of the cooking device on the first side includes the first rotating shaft 404 and the first side of the head housing 403, and the support mechanism docking side of the cooking device on the first side includes the first support member 102. The cooking device includes the second rotating shaft 405 and the second side of the head housing 403 at the head docking side on the second side, and the cooking device includes the second supporting member 103 at the support mechanism docking side on the second side.

[0122] In a possible implementation, during the switching process of the handpiece 400 from the first working position to the second working position, the buffer structure generates a constant friction force between the handpiece 400 and the main body 100. The buffer structure includes a first buffer 501, which is arranged on one of the handpiece docking side and the support mechanism docking side. The friction force between the first buffer 501 and the handpiece docking side or the support mechanism docking side generates a friction torque that prevents the handpiece 400 from rotating from the first working position to the second working position. The first buffer 501 is interference-fitted with the other of the handpiece docking side and the support mechanism docking side. The interference fit has an interference amount of 0.5 mm. If the interference amount is set too large, the friction force will increase, and the handpiece 400 may not rotate automatically. If the interference amount is too small, the buffer structure may fail due to frequent friction.

[0123] In a possible implementation, the rotating shaft is arranged on the docking side of the machine head. A first mounting groove 406 is arranged on the rotating shaft facing the docking side of the support mechanism, one end of the first buffer 501 is embedded in the first mounting groove 406, and the other end of the first buffer 501 is interference fit with the docking side of the support mechanism. Of course, the first mounting groove 406 can also be arranged on the docking side of the support mechanism facing the rotating shaft, one end of the first buffer 501 is embedded in the first mounting groove 406, and the other end of the first buffer 501 is interference fit with the rotating shaft or the part of the machine head housing 403 near the rotating shaft.

[0124] In one possible implementation, see Fig.12 , Fig.15 , Fig.18 , Fig.23 and Fig.24 , the first buffer 501 is arranged on the head docking side of the second side of the cooking device, and is interference fit with the second support member 103. The cooking device includes the second rotating shaft 405 on the head docking side of the second side, the second rotating shaft 405 includes a shaft disc 419 and a shaft rod 418, the shaft rod 418 protrudes from the shaft disc 419, the second rotating shaft 405 is connected to the head 400 through the shaft disc 419, and the shaft disc 419 is provided with at least one first mounting groove 406. The first buffer 501 has an insertion end and a contact end arranged oppositely, the insertion end enters the first mounting groove 406, the contact end is exposed outside the shaft disc 419 and is interference fit with the side wall of the second support member 103 facing the second rotating shaft 405, the outer wall of the first buffer 501 is interference fit with the groove wall of the first mounting groove 406, to prevent the first buffer 501 from being separated from the first mounting groove 406 due to the rotation of the random head 400. The shape of the insertion end of the first buffer 501 is adapted to the shape of the first mounting groove 406. The portion of the first buffer member 501 close to the insertion end is a hollow structure, and this portion can be deformed, which is more conducive to the first buffer member 501 entering the first installation groove 406, thereby improving assembly efficiency.

[0125] It can be understood that in other feasible embodiments, the first buffer member 501 can also be arranged on the second side of the head shell 403, the second support member 103, the first rotating shaft 404, the first side of the head shell 403 or the first support member 102, and the first buffer member 501 can be arranged on one or more of the above structures.

[0126] In another possible implementation, during the switching process of the handpiece 400 from the first working position to the second working position, the buffer structure gradually increases the friction between the handpiece 400 and the main body 100. The buffer structure includes a second buffer 503 and a guide rail 504. The second buffer 503 is provided on one side of the handpiece docking side and the support mechanism docking side, and the guide rail 504 is provided on the other side of the handpiece docking side and the support mechanism docking side. Before the handpiece 400 rotates from the first working position to the second working position, the second buffer 503 and the guide rail 504 are interference fit; as the handpiece 400 flips from the first working position to the second working position, the second buffer 503 moves along the guide rail 504, and within the time period T1, the friction between the second buffer 503 and the guide rail 504 gradually increases.

[0127] Specifically, the guide rail 504 is arranged on the side of the supporting mechanism docking side facing the rotating shaft, and a second mounting groove 912 is provided on the side of the rotating shaft facing the supporting mechanism docking side, one end of the second buffer member 503 is embedded in the mounting groove 912, and the other end faces the guide rail 504 on the supporting mechanism docking side.

[0128] In one possible implementation, the guide rail 504 is an arc-shaped guide rail 504 arranged around the rotation axis m, and the depth of the guide rail 504 decreases from the starting end 505 to the ending end 506. When the head 400 switches from the first working position to the second working position, the second buffer 503 moves from the starting end 505 to the ending end 506 of the guide rail 504, and within the time period T1, the friction between the top end of the second buffer 503 and the guide rail 504 gradually increases. In another possible implementation, the guide rail 504 is an arc-shaped guide rail 504 arranged around the rotation axis m, and the width of the guide rail 504 decreases from the starting end 505 to the ending end 506. When the machine head 400 switches from the first working position to the second working position, during the movement of the second buffer 503 from the starting end 505 to the ending end 506 of the guide rail 504, and within the time period T1, the friction between the side wall of the second buffer 503 and the guide rail 504 gradually increases. The guide rail 504 is arranged on the moving track of the second buffer 503 as the machine head 400 rotates, so as to ensure that the second buffer 503 can be interference-fitted with the guide rail 504 during the rotation of the machine head 400. Fig.23 and Fig.24 As shown, the movement trajectory of the second buffer member 503 surrounds the rotation axis m, the guide rail 504 is an arc-shaped guide rail 504 arranged around the rotation axis m, and the movement trajectory of the second buffer member 503 at least partially overlaps with the guide rail 504.

[0129] The second buffer 503 is arranged on the head docking side of the second side of the cooking device, and the guide rail 504 is arranged on the second support member 103. Before the head 400 rotates from the first working position to the second working position, the second buffer 503 and the guide rail 504 are interference fit. The cooking device includes the second rotating shaft 405 on the head docking side of the second side. The second rotating shaft 405 includes a shaft disc 419 and a shaft rod 418. The shaft rod 418 protrudes from the shaft disc 419. The second rotating shaft 405 is connected to the head 400 through the shaft disc 419. The shaft disc 419 is provided with at least one second mounting groove 912. The second buffer 503 has an insertion end and a contact end arranged oppositely. The insertion end enters the second mounting groove 912, and the contact end is exposed outside the shaft disc 419. The outer wall of the second buffer 503 is interference fit with the groove wall of the second mounting groove 912 to prevent the second buffer 503 from being separated from the second mounting groove 912 due to the rotation of the random head 400. The shape of the insertion end of the second buffer 503 is adapted to the shape of the second mounting groove 912. In a possible implementation, the portion of the second buffer 503 close to the insertion end is a hollow structure, which can be deformed, making it easier for the first buffer 501 to enter the second mounting groove 912. The guide rail 504 is provided on the side wall of the second support member 103 facing the second rotating shaft 405, and the guide rail 504 is an arc-shaped guide rail 504 arranged around the rotation axis m, and the depth of the guide rail 504 decreases from the starting end 505 to the ending end 506. The rotation trajectory of the second buffer 503 coincides with the guide rail 504, and the end face of the second buffer 503 exposed outside the shaft disc 419 is interference fit with the guide rail 504, and as the head 400 rotates from the first working position to the second working position, the interference between the second buffer 503 and the guide rail 504 gradually increases.

[0130] It can be understood that in another feasible embodiment, on the second side of the cooking device, the second buffer 503 can be arranged on the second side of the head housing 403 or on the second rotating shaft 405, the guide rail 504 can be arranged on the second support member 103, and the second buffer 503 and the guide rail 504 can be interchangeable; on the first side of the cooking device, the second buffer 503 can be arranged on the first side of the head housing 403 or on the first rotating shaft 404, the guide rail 504 can be arranged on the first support member 102, and the second buffer 503 and the guide rail 504 can be interchangeable. Further, the buffer structure can be arranged only on the first side or the second side of the cooking device, or on both the first side and the second side of the cooking device.

[0131] The first buffer member 501 and the second buffer member 503 can be made of a material with a good friction coefficient, such as silicone. During the rotation of the head 400, the damping resistance generated by friction keeps the head 400 from falling slowly under the action of gravity, and will not flip quickly and impact other parts. In a possible implementation, the buffer structure is symmetrically installed on the first side and the second side of the cooking device, so that the head 400 can fall slowly when the cooking device switches between the air frying mode and the frying and steaming mode.

[0132] During the switching process of the handpiece 400 from the first working position to the second working position, the maximum friction torque generated by the buffer structure is greater than the gravity torque when the handpiece 400 is in the second working position, and is less than the gravity torque of the handpiece 400 when the handpiece 400 rotates to the first preset angle. During the rotation process of the handpiece 400 from the first working position to the second working position, the time when the handpiece 400 rotates to the first preset angle is the starting time of the time period T2.

[0133] For the scheme in which the buffer structure includes a first buffer member 501, during the switching process of the head 400 from the first working position to the second working position, the buffer structure generates a constant friction force between the head 400 and the main body 100, and the friction force at any point of the rotation trajectory of the head 400 is the same. For the scheme in which the buffer structure includes a second buffer member 503 and a guide rail 504, during the switching process of the head 400 from the first working position to the second working position, the buffer structure gradually increases the friction force between the head 400 and the main body 100, and the friction force generated by the buffer structure is the largest when the head 400 rotates to the second working position. In the two embodiments of the above-mentioned buffer structure, when the head 400 rotates to the second position, the gravity torque of the head 400 is less than the friction torque generated by the buffer structure, and at this time, the speed of the head 400 is zero and will not continue to rotate, so that the head 400 will not continue to shake after rotating to the right position.

[0134] Under the premise that the center of gravity of the machine head 400 deviates from the rotation axis m, during the process of switching the machine head 400 from the first working position to the second working position, the change in the horizontal distance L1 between the center of gravity of the machine head 400 and the rotation axis is: L1 gradually increases to a maximum value, and then gradually decreases, and the gravity torque of the machine head 400 is proportional to L1, and the corresponding change in the gravity torque of the machine head 400 is: gradually increases to a maximum value, and then gradually decreases.

[0135] During the switching process of the machine head 400 from the first working position to the second working position, when the central axis of the machine head 400 forms a first preset angle with the base 101, the horizontal distance L1 between the center of gravity of the machine head 400 and the rotation axis is the largest, and the gravity moment of the machine head 400 is the largest at this time. If the friction torque corresponding to the buffer structure at this time is greater than the gravity torque of the machine head 400, the machine head 400 will hover and will not continue to rotate under the action of gravity. It is not desirable for the machine head 400 to stop before reaching the second working position. Therefore, in this embodiment, the maximum friction torque corresponding to the buffer structure is set to be less than the gravity torque of the machine head 400, and the machine head 400 can continue to rotate under the action of gravity until it reaches the second working position. The first preset angle is 90° to 135°.

[0136] The cooking device of this embodiment is provided with a buffer structure between the main body 100 and the head 400. When the cooking device is switched from the air frying mode to the frying, grilling and steaming mode, it is only necessary to apply a little force to the head 400 to assist the rotation of the head 400 when the head 400 is in the first working position. When the head 400 reaches a position where the gravity torque is greater than the friction torque, the head 400 can automatically rotate and fall under the action of gravity until it stops at the second working position. The user does not need to apply force to the head 400 throughout the process, which simplifies the user operation.

[0137] When the cooking device is in the air frying mode, if the user wants to flip the machine head 400, it is easy to forget the flipping direction. The wrong flipping direction will cause the user to touch the heating tube inside the machine head 400 during operation, thereby causing burns. In view of this problem, the present embodiment provides a reset member 600 between the machine head 400 and the support mechanism. When the machine head 400 switches from the second working position to the first working position, the machine head 400 drives the reset member 600 to twist along the first rotation direction, so that the reset member 600 transitions from a relaxed state to a compressed state; when the machine head 400 exits the first working position, the reset member 600 recovers from the compressed state to a relaxed state, and drives the machine head 400 to rotate along the second rotation direction opposite to the first rotation direction by a second preset angle to indicate the flipping direction of the machine head 400 when switching from the first working position to the second working position. This embodiment is provided with a reset member 600, so that the handpiece 400 is automatically and slowly flipped to a certain angle when it is in the first working position and unlocked, providing the user with an obvious pre-flip direction reminder, thereby reducing the probability of burns caused by the user using the wrong flip direction. The second preset angle is 45° to 90°.

[0138] See also Figure 20-Figure 22 The reset member 600 includes a coil body 601, a first torsion arm 602 and a second torsion arm 603, wherein the first torsion arm 602 extends normally outward from the head end of the coil body 601, and the second torsion arm 603 extends radially outward from the tail end of the coil body 601.

[0139] The first torsion arm 602 is disposed on one side of the machine head docking side and the support mechanism docking side, and the second torsion arm 603 is disposed on the other side of the machine head docking side and the support mechanism docking side.

[0140] Specifically, the rotating shaft is provided with a first receiving hole 408, the supporting mechanism is provided with a second receiving hole 104, the coil body 601 is pivotally mounted on the rotating shaft, the first torsion arm 602 is inserted into the first receiving hole 408, and the second torsion arm 603 is inserted into the second receiving hole 104. When the machine head 400 flips from the second working position to the first working position, the central angle between the first torsion arm 602 and the second torsion arm 603 gradually decreases, and the tension between the first torsion arm 602 and the second torsion arm 603 gradually increases. In a possible implementation, the second receiving hole 104 is a fan-shaped hole surrounding the rotation axis m, and the first baffle wall 105 and the first baffle wall 106 are respectively provided on both sides of the fan-shaped hole; when the reset member 600 is in a relaxed state, the second torsion arm 603 is between the first baffle wall 105 and the first baffle wall 106; when the machine head 400 flips from the second working position to the first working position, the machine head 400 drives the reset member 600 to rotate, so that the second torsion arm 603 abuts against the first baffle wall 106, and then drives the first torsion arm 602 to approach the second torsion arm 603.

[0141] See also Figure 12-14The reset member 600 is arranged on the second side of the cooking device, the shaft disc 419 of the second rotating shaft 405 is provided with a first receiving hole 408, and the second supporting member 103 is provided with a second receiving hole 104. The second receiving hole 104 is a fan-shaped hole surrounding the rotating axis m, and the two sides of the fan-shaped hole are respectively provided with a first blocking wall 105 and a first blocking wall 106. The first torsion arm 602 of the reset member 600 is inserted into the first receiving hole 408, the coil body 601 is sleeved on the shaft 418 of the second rotating shaft 405, and the second torsion arm 603 is inserted into the second receiving hole 104. The second torsion arm 603 can move between the first blocking wall 105 and the first blocking wall 106. When the reset member 600 is in a relaxed state, the first torsion arm 602 is limited in the first receiving hole 408, and the second torsion arm 603 is between the first retaining wall 105 and the first retaining wall 106; when the machine head 400 flips from the second working position to the first working position, the machine head 400 drives the reset member 600 to rotate along the first rotation direction. Since the first torsion arm 602 is limited in the first receiving hole 408, the first torsion arm 602 rotates with the machine head 400, and the second torsion arm 603 is driven to rotate in the second receiving hole 104 until it abuts against the first retaining wall 106. Then, the handpiece 400 continues to rotate, forcing the first torque arm 602 to continue to rotate and approach the second torque arm 603. At this time, the force applied by the handpiece 400 to the first torque arm 602 and the force applied by the second support member 103 to the second torque arm 603 are accumulated in the coil body 601. When the handpiece 400 is in a free state, the force accumulated in the coil body 601 is released, and the first torque arm 602 and the second torque arm 603 return to their original state, thereby driving the handpiece 400 to rotate a certain angle along the second rotation direction, showing the user the rotation direction of the handpiece 400 switching from the second working position to the first working position.

[0142] It is understandable that in another feasible embodiment, the reset member 600 may also be provided on the first side of the cooking device, so that the first torsion arm 602 passes through the first shaft hole, and the second torsion arm 603 passes through the second support member 103. Of course, the reset member 600 may be provided only on the first side or the second side of the cooking device, or may be provided on both the first side and the second side of the cooking device, so that the turning force on both sides of the machine head 400 is uniform.

[0143] See also Figure 20-Figure 22 The first torsion arm 602 is bent outward at a first angle from the head end of the coil body 601; the second torsion arm 603 is bent outward at a second angle from the tail end of the coil body 601, and the first angle and the second angle are in the range of 80° to 100°. Preferably, the first angle and the second angle are both 90°. Fig. 22, in the cross-sectional direction of the coil body 601, the line between the first torsion arm 602 and the center point of the cross section of the coil body 601 is the first line, the line between the second torsion arm 603 and the center point of the cross section of the coil body 601 is the second line, and the angle α between the first line and the second line is 0° to 30°. Preferably, the angle α between the first line and the second line is 10° to 20°. Of course, the first torsion arm 602 and the second torsion arm 603 can also be arranged at different angles relative to each other.

[0144] The coil body 601, the first torsion arm 602 and the second torsion arm 603 form an integrated single-piece structure. In a possible implementation, the reset element 600 is an elastic deformable body, specifically a torsion spring; and the coil body 601 is the spring winding of the torsion spring.

[0145] In this embodiment, a reset member 600 is provided between the machine head 400 and the support mechanism. When the machine head 400 is switched from the second working position to the first working position, the machine head 400 rotates along the first rotation direction around the rotation axis, and the first torsion arm 602 of the reset member 600 generates a compression force as the machine head 400 moves. As the machine head 400 descends, the compression force on the reset member 600 gradually increases. When the machine head 400 rotates to the first working position, the reset member 600 basically reaches its maximum elastic force. At this time, the machine head 400 can be locked to keep the machine head 400 in the first working position. When the machine head 400 needs to be switched to the second working position, the lock on the machine head 400 is released, and the machine head 400 is in a free state. At this time, the reset member 600 is restored, and the compression force is released, thereby driving the machine head 400 to rotate a certain angle along the second rotation direction opposite to the first direction aa, so as to show the user the correct flipping direction of the machine head 400 when the cooking device switches from the air frying mode to the frying and steaming mode.

[0146] In the case where the cooking device includes both a buffer structure and a reset member 600, when the machine head 400 is switched from the first working position to the second working position, the reset member 600 provides rotational power to the machine head 400, and the buffer structure creates friction between the machine head 400 and the supporting mechanism. The friction will reduce the elastic force of the reset member 600. To ensure that the machine head 400 rotates smoothly under the drive of the reset member 600, it is necessary to set the torque moment generated by the reset member 600 to be greater than the friction moment generated by the buffer structure when the machine head 400 starts to rotate from the first working position to the second working position. In this way, the machine head 400 can automatically rotate under the elastic force of the reset member 600, and the buffer structure can suppress the rotation speed of the machine head 400, so that the machine head 400 automatically rotates slowly, rather than suddenly rotating quickly to cause injury or fright to the user.

[0147] In the case where the cooking device includes both a buffer structure and a reset member 600, when the machine head 400 needs to be switched from the first working position to the second working position, the reset member 600 first drives the machine head 400 to deflect the second preset angle, and then the machine head 400 automatically and slowly falls under the action of gravity, and the user does not need to manually flip the machine head 400. The machine head 400 can be fully automatically flipped, which is the desired result. In order to achieve the result of automatic flipping of the machine head 400, the second preset angle is set to 45° to 90° in this embodiment. When the rotation angle of the machine head 400 along the second rotation direction is within this range, the elastic force of the reset member 600 disappears, the gravity torque of the machine head 400 gradually increases, and the friction torque of the buffer structure remains unchanged or gradually increases, but the friction torque of the buffer structure is less than the gravity torque of the machine head 400. At this time, even if no external force is applied to the machine head 400, the machine head 400 will automatically rotate under the action of gravity.

[0148] Furthermore, during the switching process of the machine head 400 from the second working position to the first working position, the reset member 600 slowly gathers torque, and at this time the reset member 600 objectively has a resistance effect. In this case, it is not necessary to use a buffer structure to create friction. Therefore, in a possible implementation, the buffer structure can be made into a retractable form, so that when the machine head 400 switches from the first working position to the second working position, it extends to create friction, and when the machine head 400 switches from the second working position to the first working position, it retracts, so that the machine head 400 slowly falls by the action of the reset member 600, rather than relying on the friction created by the buffer structure to slow down. This design can reduce the wear and tear of the reset member 600 and the number of times it is used, and extend the service life of the reset member 600.

[0149] In a possible implementation, the buffer structure further includes a first linkage component, which is connected to the first buffer 501. The first linkage component is used to drive the first buffer 501 to extend from the docking side of the head or the docking side of the support mechanism when the head 400 switches from the first working position to the second working position, so that the first buffer 501 and the opposite docking side of the head or the docking side of the support mechanism are interference-fitted within the time period T2, and, when the head 400 switches from the second working position to the first working position, drive the first buffer 501 to retract from the docking side of the head or the docking side of the support mechanism to increase the distance between the first buffer 501 and the opposite docking side of the head or the docking side of the support mechanism. Wherein, when the first buffer 501 retracts, the first buffer 501 may or may not contact the docking side, as long as the retraction action can reduce the friction of the first buffer 501. The first linkage component includes a button, which is exposed on the surface of the head housing 403 or the support mechanism, and the user drives the first buffer 501 to extend or retract by pressing the button. During the rotation of the machine head 400 from the first working position to the second working position, the first buffer component 501 and the relative machine head docking side or the supporting mechanism docking side may or may not be an interference fit throughout the entire process, as long as the friction force provided by the first buffer component 501 can stop the machine head 400 from continuing to rotate when reaching the second working position.

[0150] In another possible implementation, the buffer structure further includes a second linkage component, which is connected to the second buffer 503. The second linkage component is used to drive the second buffer 503 to extend from the docking side of the head or the docking side of the support mechanism when the head 400 switches from the first working position to the second working position, so that the second buffer 503 and the guide rail 504 on the opposite docking side of the head or the docking side of the support mechanism are interference-fitted within the time period T2, and, when the head 400 switches from the second working position to the first working position, drive the second buffer 503 to retract from the docking side of the head or the docking side of the support mechanism to increase the distance between the second buffer 503 and the guide rail 504 on the opposite docking side of the head or the docking side of the support mechanism. The second linkage component also includes a button, and the user drives the second buffer 503 to extend or retract by pressing the button. Alternatively, the buffer structure further includes a third linkage component, the third linkage component is connected to the guide rail 504, and the third linkage component is used to drive the guide rail 504 to extend from the docking side of the machine head or the docking side of the support mechanism when the machine head 400 switches from the first working position to the second working position, so that the guide rail 504 and the second buffer 503 on the opposite docking side of the machine head or the docking side of the support mechanism are interference-fitted within the time period T2, and, when the machine head 400 switches from the second working position to the first working position, drive the guide rail 504 to retract from the docking side of the machine head or the docking side of the support mechanism to increase the distance between the guide rail 504 and the second buffer 503 on the opposite docking side of the machine head or the docking side of the support mechanism. The third linkage component also includes a button, and the user drives the guide rail 504 to extend or retract by pressing the button. Similarly, when the second buffer 503 or the guide rail 504 is retracted, the second buffer 503 may or may not contact the guide rail 504, as long as the retracting action can reduce the friction between the second buffer 503 and the guide rail 504. In the process of the head 400 rotating from the first working position to the second working position, the second buffer 503 and the guide rail 504 on the opposite side of the head docking or the supporting mechanism docking may be interference fit throughout the process, or may not be interference fit throughout the process, as long as the friction between the second buffer 503 and the guide rail 504 can stop the head 400 from rotating further when the head 400 reaches the second working position.

[0151] See also Fig. 27, which shows the rotation process of the machine head 400 when the cooking device switches from the air frying mode to the frying and steaming mode, specifically including: when the machine head 400 is in the first working position, the reset member 600 is compressed, when the machine head 400 is unlocked, the reset member 600 drives the machine head 400 to rotate, when the machine head 400 rotates to the second preset angle, the elastic force of the reset member 600 disappears, and the machine head 400 continues to rotate under the action of gravity, and the machine head 400 rotates to the second preset angle ( Fig. 27 However, due to the friction between the head 400 and the supporting structure caused by the buffer structure, the rotation speed of the head 400 is reduced, causing the head 400 to fall slowly until the head 400 rotates to the second working position. The friction torque corresponding to the buffer structure is equal to or greater than the gravity torque of the head 400. At this time, the speed of the head 400 drops to zero and stops at the second working position.

[0152] See also Figure 5 and Figure 6 The head 400 includes a head shell 403, a motor 410, a fan assembly 411 and a heating module 412; the head shell 403 has a heating chamber 413, a cooling chamber 414, an air inlet and an air outlet 416, the heating chamber 413 has the heating opening 401, the cooling chamber 414 is located on the side of the heating chamber 413 away from the heating opening 401, and the air inlet and the air outlet 416 are connected to the cooling chamber 414; the heating module 412 is arranged in the heating chamber 413, the motor 410 and the fan assembly 411 are arranged in the cooling chamber 414, and the output shaft of the motor 410 is connected to the fan assembly 411.

[0153] The mass of the machine head 400 is about 1200g-2800g. The machine head 400 and the first pot body 200 constitute a first complete machine, and the weight ratio of the machine head 400 to the first complete machine is 0.2-0.5. The main body 100, the machine head 400 and the second pot body 300 constitute a second complete machine, and the weight ratio of the first complete machine to the second complete machine is 0.8-2. Since the heavier components are almost all arranged in the machine head 400, the mass of the machine head 400 is large, so when the machine head 400 is turned over, there is a phenomenon that the machine head 400 falls rapidly due to the action of gravity.

[0154] See also Figure 2 and Figure 4 , the rotation axis m is close to the heating opening 401. When the head 400 is located at the first working position, the ratio between the distance from the rotation axis m to the base 101 and the distance from the top surface of the head 400 to the base 101 is 2 / 3.

[0155] The handpiece 400 is provided with a flip auxiliary component 417. Specifically, the flip auxiliary component 417 is provided on a side of the handpiece housing 403 away from the heating port. When the handpiece 400 is located at the first working position, the flip auxiliary component 417 is located on the far side of the top of the handpiece 400. When the handpiece 400 is driven by the reset component 600 to rotate to the second preset angle, the flip auxiliary component 417 is just located at the top, which is convenient for the user to apply force to the flip auxiliary component 417. When the handpiece 400 is in the second working position, the flip auxiliary component 417 is located on the near side of the top of the handpiece 400. The user pushes against the flip auxiliary component 417 to push the handpiece 400 from the near side to the far side, thereby switching the handpiece 400 from the second working position to the first working position. Fig.26 shown.

[0156] See also Figure 1 and Figure 7 , the base 101 includes a placement area 109. The cooking device also includes a power board 800 arranged on the main body 100, and the power board 800 is arranged away from the placement area 109 of the base 101. Traditionally, the power board 800 is arranged on the machine head 400. Since a heating mechanism is provided on the machine head 400, the temperature of the inner cavity of the head 400 is relatively high when the cooking device is working, which affects the service life of the components on the power board 800, and further affects the service life of the power board 800. In the present application, the power board 800 is arranged away from the machine head 400, and also away from the placement area 109 of the base 101, thereby avoiding the influence of temperature on the service life of the power board 800.

[0157] See also Figure 1 , the cooking device also includes an operating component 110 disposed on the main body 100, and the operating component 110 is disposed away from the placement area 109 of the base 101. As with the position setting of the power board 800 mentioned above, the setting of the operating component 110 in the present application can also avoid the influence of temperature on the service life of the operating component 110; it can also simplify the structure of the head 400, and through the reasonable layout of the structure inside the head 400, the height of the head 400 can be reduced to help achieve the miniaturization of the cooking device. In addition, since the operating component 110 is disposed on the main body 100, the operating component 110 will not change position with the rotation of the head 400, so after the head 400 rotates to change the working position, it will not affect the user's operation of the operating component 110.

[0158] The operating component 110 is disposed on the base 101. To facilitate user operation, the operating component 110 can be disposed on the front side of the placement area 109 of the base 101. Of course, the operating component 110 can also be disposed on a supporting mechanism. Optionally, the operating component 110 includes a touch display panel, and is operated by touch. It is understood that in other feasible embodiments, the operating component 110 is not limited thereto, and for example, can also include an operating button or an operating knob, and is operated by pressing an operating button or rotating an operating knob.

[0159] See also Figure 3 The first pot body 200 includes a handle 201. When the first pot body 200 is placed on the base 101, along the first direction aa, the proximal edge of the handle 201 is located proximal to the proximal edge of the operating component 110, thereby avoiding a significant impact on the overall occupied space of the cooking device due to a change in the position of the operating component 110.

[0160] The cooking device further includes a retaining structure for retaining the machine head 400 in the first working position. Specifically, the retaining structure includes a groove 701 and a protrusion 702 that match each other, the groove 701 being provided on one side of the machine head docking side and the support mechanism docking side, and the protrusion 702 being provided on the other side of the machine head docking side and the support mechanism docking side.

[0161] See also Figure 8 and Fig. 9 In a feasible embodiment, the retaining structure includes a groove 701 provided on the first support member 102 and a protrusion 702 provided on the first rotating shaft 404, and the groove 701 matches the protrusion 702. Of course, the groove 701 can also be provided on the second support member 103, and the protrusion 702 can be provided on the second rotating shaft 405. The positions of the protrusion 702 and the corresponding groove 701 can also be exchanged. When the head 400 is in the first working position, the protrusion 702 of the head 400 is inserted into the groove 701, and the relative position of the head 400 and the main body 100 is limited by the protrusion 702 and the groove 701, thereby ensuring the stability of the head 400. It can be understood that when the working position of the head 400 needs to be adjusted, the protrusion 702 can also be disengaged from the groove 701 to facilitate the rotation of the head 400. The setting of the holding structure enables the head 400 to be more stably maintained in the first working position, thereby better preventing the first pot body 200 and the main body 100 from being damaged due to the instability of the head 400, thereby increasing the service life of the first pot body 200 and the main body 100.

[0162] The cooking device further includes a limiting structure for limiting the head 400 from continuing to rotate when it rotates along the first rotation direction to the first limit rotation position, and limiting the head 400 from continuing to rotate when it rotates along the second rotation direction to the second limit rotation position. Specifically, the limiting structure includes a limiting portion and a stopper, the limiting portion is provided on one side of the head docking side and the support mechanism docking side, and the stopper is provided on the other side of the head docking side and the support mechanism docking side. The limiting portion includes a first limiting portion 703 and a second limiting portion 704, and the stopper includes a first stopper 705 and a second stopper 706, the first limiting portion 703 matches the first stopper 705, and is used to continue to rotate when the head 400 rotates along the first rotation direction to the first limit rotation position; the second limiting portion 704 matches the second stopper 706, and is used to continue to rotate when the head 400 rotates along the second rotation direction to the second limit rotation position, and the second rotation direction is opposite to the first rotation direction.

[0163] Specific to Fig.10 and Fig.11 In the embodiment shown, the first rotation direction is Fig.10 and Fig.11 In the clockwise direction of the viewing direction shown, the first limit rotation position of the corresponding head 400 is shown in FIG. Fig.10 The second rotation direction is Fig.10 and Fig.11 In the counterclockwise direction of the viewing direction, the corresponding second limit rotation position of the head 400 is shown in FIG. Fig.11 shown.

[0164] The limiting structure is used to limit the head 400 from continuing to rotate when it rotates along the first rotation direction to the first extreme rotation position, and to limit the head 400 from continuing to rotate when it rotates along the second rotation direction to the second extreme rotation position. The setting of the limiting structure can prevent the head 400 from rotating 360 degrees relative to the support mechanism, thereby preventing the wires and signal lines from being entangled due to the rotation of the head 400, and thereby preventing the wires and signal lines from being damaged due to local force concentration, so as to ensure the stability of the electrical connection and signal connection in the cooking device.

[0165] It is understandable that the setting of the limiting structure enables the head 400 to rotate only between the first limit rotation position and the second limit rotation position. More specifically, Fig.10 and Fig.11In the illustrated embodiment, the first working position of the machine head 400 is the same as the first extreme rotation position, and the second working position of the machine head 400 is the same as the second extreme rotation position. In other words, the rotation angle of the machine head 400 from the first extreme rotation position to the second extreme rotation position is 180 degrees. Of course, in another feasible embodiment, the first working position of the machine head 400 is not limited to coincide with the first extreme rotation position, and can be located between the first extreme rotation position and the second extreme rotation position. Similarly, the second working position is not limited to coincide with the second extreme rotation position, and can be located between the first extreme rotation position and the second extreme rotation position.

[0166] Fig.12 and Fig.19 , a specific implementation of the limiting structure is given. Specifically, the machine head 400 has a second rotating shaft 405. The second support member 103 has a second rotating hole matching the second rotating shaft 405. The limiting structure includes a first limiting portion 703 and a second limiting portion 704 provided on the second rotating shaft 405, and a first stop portion 705 and a second stop portion 706 provided on the second support member 103; the first limiting portion 703 matches the first stop portion 705 to prevent the machine head 400 from continuing to rotate when the machine head 400 rotates to the first extreme rotation position along the first rotation direction. The second limiting portion 704 matches the second stop portion 706 to prevent the machine head 400 from continuing to rotate when the machine head 400 rotates to the second extreme rotation position along the second rotation direction.

[0167] The limiting structure includes a limiting block 707 disposed on the second rotating shaft 405, and the first limiting portion 703 and the second limiting portion 704 are the ends of the limiting block 707 along the circumferential direction. The limiting structure includes a stopper block 708 disposed on the first supporting body, and the first stopper 705 and the second stopper 706 are the ends of the stopper block 708. In other words, in this embodiment, the first limiting portion 703 and the second limiting portion 704 are integrally formed, and the first stopper 705 and the second stopper 706 are integrally formed. Of course, it can be understood that in other embodiments, the first limiting portion 703 and the second limiting portion 704 can also be independently provided, and the first stopper 705 and the second stopper 706 can also be independently provided.

[0168] See also Fig.13 and Fig.15, the first limiting portion 703 has a first limiting surface 709, the second limiting portion 704 has a second limiting surface 710, the first stopping portion 705 has a first stopping surface 711, and the second stopping portion 706 has a second stopping surface 712. When the machine head 400 is located at the first extreme rotation position, the second limiting surface 710 and the second stopping surface 712 are coplanar, and the first limiting surface 709 and the first stopping surface 711 are in contact with each other. When the machine head 400 is located at the second extreme rotation position, the first limiting surface 709 and the first stopping surface 711 are coplanar, and the second limiting surface 710 and the second stopping surface 712 are in contact with each other.

[0169] Optionally, the limit block 707 is fan-shaped, and the stop block 708 is fan-shaped. It is understandable that in other feasible implementations, the limit block 707 and the stop block 708 are not limited to being fan-shaped, and can also be any other regular or irregular shape.

[0170] It is understandable that, in other feasible embodiments, the limiting structure is not limited to being arranged on the second side of the handpiece 400. For example, specifically, the limiting structure includes a third limiting portion and a fourth limiting portion arranged on the first rotating shaft 404, and a third stop portion and a fourth stop portion arranged on the first supporting body; the third limiting portion matches the third stop portion, so that the handpiece 400 continues to rotate when it rotates to the first extreme rotation position along the first rotation direction; the fourth limiting portion matches the fourth stop portion, so that the handpiece 400 continues to rotate when it rotates to the second extreme rotation position along the second rotation direction.

[0171] Similarly, it is feasible to simultaneously set the limiting structures on both sides of the handpiece 400. It is understandable that the specific structure of the limiting structure located on the first side of the handpiece 400 and the specific structure of the limiting structure located on the second side of the handpiece 400 may be the same or different, but what needs to be satisfied is that the two limit rotation positions of the handpiece 400 defined by the two limiting structures are the same.

[0172] The cooking device further includes a locking structure, which is used to lock the head 400 to prevent the head 400 from rotating relative to the body 100. This can ensure the working stability of the cooking device in various working modes and avoid unexpected rotation.

[0173] In one embodiment, if Figure 12-Figure 19As shown, the locking structure includes a locking member 901, which is movably arranged relative to the second support member 103. A locking hole is arranged on the head housing 403 of the head 400. The locking member 901 is configured to lock the head 400 when inserted into the locking hole, and when the locking member 901 is disengaged from the locking hole, the head 400 can rotate relative to the second support member 103. It can be understood that the number of the locking holes is not limited to Fig.15 The two shown in the figure may also be one, three, four or more.

[0174] In one embodiment, if Fig.12 and Fig.16 As shown, a guide groove 113 is formed on the second support member 103, and a guide portion 902 is formed on the locking member 901.

By providing the guide groove 113 and the guide portion 902, the locking member 901 can be stably moved along a predetermined direction to lock the machine head 400. It can be understood that the guide groove 113 and the guide portion 902 are arranged one by one, and the number of the two is not limited to Fig.12 The two shown in the figure may also be one, three, four or more.

[0175] In one embodiment, if Fig.12 As shown, the locking member 901 includes a latch portion 903, which is plugged into the locking hole. Preferably, one end of the latch portion 903 for inserting into the locking hole is formed into a cone shape, which is conducive to guiding the latch portion 903 to be smoothly inserted into the locking hole. It can be understood that the latch portions 903 and the locking holes are arranged one by one, and the number of the latch portions 903 is also not limited to Fig.12 The two shown in the figure may also be one, three, four or more.

[0176] In one embodiment, if Fig.16 As shown, the locking member 901 is disposed in the inner cavity 111, and a first guide hole 112 is disposed on the inner side wall of the inner cavity 111, and the latch portion 903 passes through the first guide hole 112 and is inserted into the locking hole. By providing the first guide hole 112, the movement stability of the locking member 901 can be further improved. It can be understood that the first guide holes 112 can be provided one-to-one with the latch portion 903 and the locking hole, and the number of the first guide holes 112 is not limited to Fig.16 The two shown in the figure may also be one, three, four or more.

[0177] In one embodiment, if Figure 12-14As shown, the locking structure also includes a first elastic reset member 906, which is connected to the locking member 901 and the outer side wall of the inner cavity 111 respectively, and is used to keep the locking member 901 inserted into the locking hole. By providing the first elastic reset member 906, the locking member 901 can always be stably inserted into the locking hole, thereby improving the locking reliability of the locking structure. Among them, the first elastic reset member 906 can be an elastic reset member 600 in the form of a spring or other structural form. It can be understood that the number of the first elastic reset member 906 is not limited to Fig.14 The two shown in the figure may also be one, three, four or more.

[0178] In one embodiment, if Fig.12 , Fig.14 and Fig.17 As shown, a mounting post 904 is provided on the locking member 901, a mounting groove 912 is provided on the outer side wall of the inner cavity 111, one end of the first elastic reset member 906 is sleeved on the mounting post 904, and the other end is installed in the mounting groove 912. By providing the mounting post 904 and the mounting groove 912, on the one hand, the installation of the first elastic reset member 906 is facilitated, and on the other hand, the working stability of the first elastic reset member 906 can be improved. It can be understood that the mounting post 904 and the mounting groove 912 are provided in a one-to-one correspondence, and each pair of the mounting post 904 and the mounting groove 912 corresponds to one first elastic reset member 906.

[0179] In one embodiment, as shown in FIG. Fig.14 , Fig.18 , Fig.19 As shown, the locking structure further includes an actuating member 907, which can move relative to the second supporting member 103 to drive the locking member 901 to disengage from the locking hole. Fig.12 , Fig.14 and Fig.18 As shown, the actuator 907 is provided with a driving column 908, and the lower end of the driving column 908 forms a first inclined surface 909 actuating inclined surface, and the locking member 901 is formed with a second inclined surface 905 actuating inclined surface, and the actuator 907 drives the locking member 901 to move through the cooperation of the first inclined surface 909 and the second inclined surface 905. It should be understood that at least one of the actuator 907 and the locking member 901 forms an actuating inclined surface, so that the actuator 907 can drive the locking member 901 to move through the actuating inclined surface, and it is not necessary for both to form an actuating inclined surface. It can be further understood that the number of driving columns 908 is not limited to Fig.12 The two shown may also be one, three, four or more. In addition, the present application is not limited thereto, and the actuating member 907 may also drive the locking member 901 to move out of the locking hole in other ways.

[0180] In one embodiment, if Fig.14 , Fig.16 As shown, the second support member 103 is provided with a mounting opening 116, and the actuator 907 is disposed on the second support member 103 through the mounting opening 116. Optionally, the mounting opening 116 is disposed at the top of the second support member 103, and the actuator 907 is configured to be able to move relative to the second support member 103 in a vertical direction. Of course, it can be understood that the moving direction of the brake member is not limited thereto, as long as it can drive the locking member 901 to disengage from the locking hole.

[0181] In one embodiment, if Fig.12 and Fig.14 As shown, the locking structure also includes a second elastic reset member 911, which is connected to the actuator 907 and the second support member 103 respectively, and is used to cause the actuator 907 to reset. By setting the second elastic reset member 911, the actuator 907 can automatically reset after being operated, which simplifies the operation and improves the user experience. Among them, the second elastic reset member 911 can be an elastic reset member 600 in the form of a spring or other structural forms. It can be understood that the actuator 907 abuts against the inner wall surface of the second support member 103 under the action of the second elastic reset member 911, and a blocking structure is formed on the second support member 103 to prevent the actuator 907 from disengaging from the second support member 103.

[0182] In one embodiment, if Fig.14 and Fig.19 As shown, a mounting guide post 910 is provided on the actuator 907, and a support plate 114 is provided on the inner side wall of the inner cavity 111.
