[0034] Implementation of the reverse:

[0035] Please refer to Figures 1 to 7An easy-to-clean intelligent cooking device is shown, which is in the form of a cooking pot, comprising a cover body 2 and a base body 1, wherein the cover body 2 is connected to the base body 1. Specifically, the cover body 2 in this embodiment is reversibly connected to the base body 1 through a rotating pin structure, and the base body 1 has a connecting seat 10, which is fixedly mounted on the base body 1. A pin hole is provided on the connecting seat 10 and the connecting arm 24 of the cover body 2, and the rotating pin passes through the pin hole to flexibly hinge the connecting seat 10 and the connecting arm 24 together so that the connecting arm 24 is reversibly connected to the connecting seat 10. Both the connecting arm 24 and the connecting seat 10 are made of plastic. When the connecting arm 24 is flipped backward around the central axis of the pin shaft, the pot cover 23 can be opened to an open cover state, and when it is flipped forward, the pot cover 23 can cover the cooking pot to a closed cover state.

[0036] The cover 2 is provided with a stirring member 22 which extends into the base 1 when the cover is closed. The stirring member 22 can rotate around its axis to stir the food in the wok. The connecting arm 24 is provided with a driving device 20 which drives the stirring member 22 to perform stirring via a transmission mechanism 21. The transmission mechanism 21 includes:

In the present embodiment, a sliding bearing 2136 is used to reduce costs.

[0040] The connecting shaft 212 passes through the fixed cover 2131 and the movable cover 2132, and drives the movable cover 2132 to rotate relative to the fixed cover 2131. The connecting shaft 212 and the movable cover 2132 are locked and connected in the axial direction thereof by a locking piece, and are transmission connected in the circumferential direction thereof by a bite structure. After the locking piece is removed, the planetary gear assembly 213 can be detached from the connecting shaft 212 as a whole along the axial direction of the connecting shaft 212.

[0041] The driving device 20 includes a rotating motor 201 and a worm gear assembly 202. The worm is fixed on the motor shaft of the rotating motor 201. In this embodiment, the two are integrally arranged. The worm wheel is fixedly connected to the driving shaft 211. The two are meshed by a flat key interference fit. In other embodiments, any transmission mechanism that can convert a rotational motion in one direction into a rotational motion in another direction perpendicular thereto can be used in the invention, such as a bevel gear structure.

[0044] Specifically, the coupling shaft 212 has an outer hexagon, and correspondingly, the movable cover 2132 has an inner hexagon, and the outer hexagon and the inner hexagon mesh with each other to form a meshing structure. In other embodiments, any mechanism that can achieve meshing transmission can be applied to the invention, such as a triangular shaft and a triangular hole, a quadrangular shaft and a quadrangular hole, and a cylindrical outer gear and an inner gear ring. Mechanisms of mutual meshing transmission can all be used in the invention.

[0045] The movable cover 2132 and the fixed cover 2131 are connected by a rolling bearing 2130, which is a deep groove ball bearing. The movable cover 2132 is fixedly connected to the inner ring of the rolling bearing 2130, and the fixed cover 2131 is fixedly connected to the outer ring of the rolling bearing 2130. In other embodiments, it should not be limited to the rolling bearing 2130, and a sliding bearing can also be used in this position.

[0046] The planetary gear shaft 2135 is mounted on the movable cover 2132 through a sliding bearing 2136 or a rolling bearing, and can rotate with the movable cover 2132. The movable cover 2132 has a bottom wall and an annular vertical wall, and the locking member is a locking nut 214. The connecting shaft 212 passes through the bottom wall and is locked with the locking nut 214. The annular vertical wall and the fixed cover 2131 intersect and there is an escape gap between the two. To match the locking nut 214, the lower end of the connecting shaft is provided with an external thread adapted thereto. Of course, the purpose of providing the locking structure is to detachably mount the planetary gear assembly 213 and the pot cover 23 on the connecting arm 24. Therefore, the locking structure should not be limited to the threaded locking structure, and other types of locking structures may also be applicable, such as an elastic retaining spring structure, a screw-on structure, etc.

[0047] The movable cover 2132 and the fixed cover 2131 are interlocked and form a cavity therebetween, the planetary gear 2134 and the sun gear 2133 are both arranged in the cavity, the connecting shaft 212 passes through the cavity and has two ends protruding from the outside of the fixed cover 2131 and the movable cover 2132, the two ends respectively forming a drive shaft 211 connection part and a locking member connection part, the two ends of the planetary gear shaft 2135 respectively forming a planetary gear 2134 connection part and a stirring member 22 connection part, wherein the planetary gear 2134 connection part is located in the cavity, and the stirring member 22 connection part protrudes from the outside of the bottom wall of the movable cover 2132.

The lower ends of the upper cover and the lower cover have pin holes that overlap each other for the pin shaft to pass through. The driving device 20 includes a motor 201, a worm and a worm wheel. The motor 201 can be an AC series motor or a DC motor. In this embodiment, since the stirring power during cooking is not large, a low-power DC motor is used to reduce noise. The worm is directly processed on the output shaft of the motor 201, and the worm wheel is connected to the driving shaft 211 through a flat key interference fit. The two ends of the driving shaft 211 are respectively installed on the lower cover and the upper cover through rolling bearings, and its lower end passes through the worm wheel cover.

[0050] In order to prevent oil from entering the cavity inside the connecting arm 24 and contaminating the worm gear when cooking, a sealing ring is provided between the drive shaft 211 and the through hole on the lower cover, and a sealing ring is also provided between the pot cover 23 and the lower cover. Specifically, a circular groove is provided on the lower cover, and the sealing ring is an O-ring. The sealing ring is embedded in the circular groove, and part of it protrudes out of the circular groove to form a seal between the pot cover 23 and the lower cover.

[0051] like Figure 6 As shown, as a further optimization, in order to prevent the pot cover 23 from rotating around the axis of the driving shaft 211, three positioning holes are set on the pot cover 23, and three positioning columns are set on the fixed cover 2131. The positioning columns are inserted into the positioning holes to limit the rotation of the pot cover 23.

[0052] like Figure 2 and Figure 7 As shown, the coupling shaft 212 is connected to the drive shaft 211 through a pin structure, the upper part of the coupling shaft 212 has a blind hole, the tail end of the drive shaft 211 is inserted into the blind hole, the drive shaft 211 and the side wall of the blind hole are both provided with pin holes, and the pin is inserted into the pin hole to achieve the connection between the two. However, the structural strength of this connection is not high. In order to increase the transferable torque, in this embodiment, the tail end of the drive shaft 211 is set as a D-shaped shaft, and the blind hole of the coupling shaft 212 is also set as a D-shaped hole. The two are adapted to improve the strength of the connection.

[0053] exist Figure 2 In the embodiment, a mounting cavity for mounting the planetary gear 2134 is formed between the movable cover 2132 and the fixed cover 2131 of the planetary gear assembly 213. The movable cover 2132 is a ring-shaped vertical wall protruding upwards from the lower part. The inner circumference of the ring-shaped vertical wall is larger than the outer circumference of the fixed cover 2131. The fixed cover 2131 is surrounded in the middle, and there is a gap between the two. The connecting shaft 212 passes through the through holes in the middle of the movable cover 2132 and the fixed cover 2131, and the outer hexagon on the connecting shaft 212 and the inner hexagon on the movable cover 2132 are engaged with each other to realize transmission. The movable cover 2132 is connected to the fixed cover 2131 through a rolling bearing 2130. The outer ring of the rolling bearing 2130 is fixedly embedded in the fixed cover 2131.
