[0005] In order to achieve the above-mentioned purpose, according to one aspect of the present invention, a drive assembly for cooperating with a pot body and a cover assembly is provided, the drive assembly comprising: a lower drive structure, arranged on the pot body, the lower drive structure comprising an operating part exposed outwardly from the pot body and a first rotating transmission member rotatably arranged on the pot body; an upper drive structure, arranged on the cover assembly, the upper drive structure comprising a second rotating transmission member and a drive portion, the second rotating transmission member can cooperate with the first rotating transmission member to prevent rotation and can rotate synchronously with the first rotating transmission member, the drive portion is driven and cooperated with the locking member of the cover assembly to drive the locking member to switch between a locked position and an unlocked position; wherein the first rotating transmission member and the second rotating transmission member have a unique cooperation state.

[0006] By applying the technical solution of the present invention, a lower driving structure including an operating part and a first rotating transmission member is provided on the pot body, and an upper driving structure including a second rotating transmission member and a driving part is provided on the cover assembly, so that a user can drive the first rotating transmission member to rotate by operating the operating part located on the pot body, the second rotating transmission member is engaged with the first rotating transmission member to stop rotation and can rotate together with the first rotating transmission member, the driving part is provided between the second rotating transmission member and the locking member, and when the second rotating transmission member rotates, the locking member is driven by the driving part to switch between the locked position and the unlocked position. That is, through the above-mentioned arrangement, the operating part for user operation is provided on the pot body, the driving force of the operating part can be transmitted to the locking member in turn through the first rotating transmission member, the second rotating transmission member and the driving part and drive the locking member to switch positions, which can free up the space above the cover assembly, thereby enabling a relatively large control panel to be provided on the cover assembly, which is convenient for user use. Furthermore, by ensuring that the first and second rotating transmission members have a unique mating state, alignment between the locking member and the corresponding structure on the pot body, as well as alignment between the first and second rotating transmission members, can be simultaneously ensured during the lid closing process. Therefore, the technical solution of this application can effectively address the issues in related arts such as the inappropriate placement of the control panel or the small size of the control panel, which affect the user experience.

[0007] Furthermore, a plug-in structure is provided between the first and second rotating transmission members. The plug-in structure includes a slot for interlocking rotation and an interlocking protrusion. The slot is provided on one of the first and second rotating transmission members, and the interlocking protrusion is provided on the other of the first and second rotating transmission members. The interlocking slot and the interlocking protrusion achieve the docking between the first and second rotating transmission members and enable them to rotate synchronously, thus having the advantages of simple structure and reliable transmission.

[0009] Furthermore, a friction transmission structure is provided between the first and second rotating transmission members. The friction transmission structure includes a first friction member and a second friction member that engage in frictional rotation-locking engagement. The first friction member is provided on the first rotating transmission member, and the second friction member is provided on the second rotating transmission member. The friction engagement between the first and second friction members enables the second rotating transmission member to rotate synchronously with the first rotating transmission member.

[0010] Furthermore, the drive assembly further comprises: a first locking member disposed on the pot body, which locks the lower drive structure when the lid assembly is separated from the pot body; and / or a second locking member disposed on the lid assembly, which locks the upper drive structure when the lid assembly is separated from the pot body. The first locking member is capable of locking the position of the lower drive structure when the lid is open, thereby maintaining the first rotary drive member in a specific position; and the second locking member is capable of locking the position of the upper drive structure when the lid is open, thereby maintaining the second rotary drive member and the locking member in a specific position, thereby ensuring the docking effect of the second rotary drive member and the first rotary drive member during the closing process, and the misalignment between the lid teeth and the pot teeth.

[0011] Furthermore, the first rotary transmission member includes a lower gear and a lower coupling member that are connected to each other in a rotationally fixed manner. The pot body has a lower transmission cylinder. The lower coupling member is disposed within the lower transmission cylinder from top to bottom and engages with a stopper on the upper surface of the lower transmission cylinder. The lower gear is disposed within the lower transmission cylinder from bottom to top and engages with a stopper on the lower surface of the lower transmission cylinder. Providing the first rotary transmission member with a separate lower gear and lower coupling member, with the lower coupling member and lower gear respectively engaging with the upper and lower surface stops of the lower transmission cylinder, can prevent the first rotary transmission member from being driven downward or pulled upward during the process of pressing down or lifting the cover assembly, thereby ensuring the installation stability of the first rotary transmission member.

[0012] Furthermore, the operating portion includes an operating knob extending outward from the pot body and a translational transmission member located within the pot body. Rotating the operating knob drives the translational transmission member, which in turn drives the lower gear. The translational transmission member is disposed between the operating knob and the lower gear and cooperates with both to convert rotation of the operating knob about the horizontal axis into rotation of the lower gear about the vertical axis.

[0013] Furthermore, the operating knob includes a knob body and a transmission rod disposed on the knob body, the transmission rod extending toward the interior of the pot body and offset from the center of the knob body. The translational transmission member is provided with a mating groove, and the transmission rod is disposed within the mating groove to drive the translational transmission member to move. Alternatively, the translational transmission member is provided with lower drive teeth, and the lower gear is provided with lower driven teeth that mesh with the lower drive teeth.

[0043] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only some embodiments of the present invention, not all embodiments. The following description of at least one exemplary embodiment is actually only illustrative and is in no way intended to limit the present invention and its application or use.

It should be noted that similar numbers and letters represent similar items in the following figures, and therefore, once an item is defined in one figure, it does not need to be further discussed in subsequent figures.

[0046] like Figure 1 、 Figure 2 and Figure 10As shown, the present application provides a drive assembly for cooperating with a pot body 1 and a cover assembly 2. The first embodiment of the drive assembly of the present application includes a lower drive structure and an upper drive structure. The lower drive structure is arranged on the pot body 1, and the lower drive structure includes an operating portion 10 exposed to the outside of the pot body 1 and a first rotary transmission member 20 rotatably arranged on the pot body 1; the upper drive structure is arranged on the cover assembly 2, and the upper drive structure includes a second rotary transmission member 30 and a drive unit 40. The second rotary transmission member 30 can be engaged with the first rotary transmission member 20 to prevent rotation and can rotate synchronously with the first rotary transmission member 20. The drive unit 40 drives and cooperates with the locking member 3 of the cover assembly 2 to drive the locking member 3 to switch between a locked position and an unlocked position; wherein, the first rotary transmission member 20 and the second rotary transmission member 30 have a unique engagement state.

[0047] By applying the technical solution of this embodiment, a lower drive structure including an operating portion 10 and a first rotary transmission member 20 is provided on the pot body 1, and an upper drive structure including a second rotary transmission member 30 and a drive unit 40 is provided on the lid assembly 2. This allows a user to rotate the first rotary transmission member 20 by operating the operating portion 10 located on the pot body 1. The second rotary transmission member 30 is fixedly engaged with the first rotary transmission member 20 and can rotate along with the first rotary transmission member 20. The drive unit 40 is disposed between the second rotary transmission member 30 and the locking member 3. When the second rotary transmission member 30 rotates, the drive unit 40 drives the locking member 3 to switch between a locked position and an unlocked position. In other words, the above arrangement enables the operating portion 10 for user operation to be disposed on the pot body 1. The driving force of the operating portion 10 can be sequentially transmitted to the locking member 3 through the first rotary transmission member 20, the second rotary transmission member 30, and the drive unit 40, thereby driving the locking member 3 to switch positions. This frees up space above the lid assembly, thereby allowing a relatively large control panel to be provided on the lid assembly, facilitating user use. Furthermore, by ensuring that the first and second rotary transmission members 20 and 30 have a unique mating state, the alignment between the locking member 3 and the corresponding structure on the pot body 1 (i.e., the offset docking between the lid teeth on the locking member 3 and the pot teeth on the pot body 1) and the alignment between the first and second rotary transmission members 20 and 30 can be simultaneously ensured during lid closing. Therefore, the technical solution of this embodiment effectively solves the problem in related arts of an inappropriate control panel location or a small control panel area that affects the user experience.

[0048] It should be noted that the above-mentioned "the operating part 10 is exposed outward from the pot body 1" is not limited to the operating part 10 extending outward from the pot body 1. The outer end of the operating part may not protrude from the pot body, and an operating recess is provided on the pot body for the user to insert his hand into to operate the operating part.

[0049] Specifically, the locking member 3 is provided with a cover tooth, and the pot body 1 is fixedly provided with a pot tooth. When the cover assembly 2 is covered on the pot body 1, the user can operate the operating part 10 to drive the locking member 3 to move between a position where the cover tooth and the pot tooth are directly opposite (i.e., a locked position) and a position where the cover tooth and the pot tooth are misaligned (i.e., an unlocked position).

[0050] In this embodiment, the first rotating transmission member 20 and the second rotating transmission member 30 are both rotating members, and both rotate around their own axes. The above-mentioned "the first rotating transmission member 20 and the second rotating transmission member 30 have a unique matching state" refers to the range of 360°. When the posture of the first rotating transmission member 20 is determined, the second rotating transmission member 30 can only dock with the first rotating transmission member 20 at a specific angle within the range of 360°. When the second rotating transmission member 30 rotates to other positions, it cannot be plugged in and matched with the first rotating transmission member 20. In this way, during the closing process, by properly setting the posture of the first rotary transmission member 20, when the cover assembly 2 is pressed down, the second rotary transmission member 30 can only be connected to the first rotary transmission member 20 when it rotates to a specific angle. At this time, the pot teeth and the cover teeth are exactly misaligned, ensuring that the cover assembly 2 can be smoothly pressed down. At the same time, after the user subsequently operates the operating part 10 according to the set operation amount, the first rotary transmission member 20, the second rotary transmission member 30 and the driving part 40 can exactly drive the locking member 3 to a position where the cover teeth and the pot teeth are aligned, that is, drive the locking member 3 to switch from the unlocked position to the locked position. This setting can avoid the situation where the first rotary transmission member 20 and the second rotary transmission member 30 can be connected, but the pot teeth and the cover teeth partially overlap when the cover assembly 2 is pressed down, affecting further downward pressure of the cover assembly 2, or the situation where the first rotary transmission member 20 and the second rotary transmission member 30 can be inserted, but after the user operates the operating part 10 according to the set operation amount, the pot teeth and the cover teeth partially align, so that the pressure bearing capacity between the pot teeth and the cover teeth does not meet the requirements.

[0051] In this embodiment, the operating portion 10 and the first rotating transmission member 20 are separate structures, and the second rotating transmission member 30 and the driving portion 40 are separate structures. Of course, in embodiments not shown in the figures, the operating portion and the first rotating transmission member can also be an integrated structure, and the second rotating transmission member and the driving portion can also be an integrated structure.

[0052] like Figure 1 and Figure 2As shown, a plug-in structure 50 is provided between the first rotating transmission member 20 and the second rotating transmission member 30. The plug-in structure 50 includes a slot 51 for interlocking and anti-rotational engagement and an interlocking protrusion 52. The slot 51 is provided on one of the first rotating transmission member 20 and the second rotating transmission member 30, and the interlocking protrusion 52 is provided on the other of the first rotating transmission member 20 and the second rotating transmission member 30. The interlocking slot 51 and the interlocking protrusion 52 achieve the docking between the first rotating transmission member 20 and the second rotating transmission member 30 and enable them to rotate synchronously, which has the advantages of simple structure and reliable transmission.

[0053] Specifically, the slot 51 and the insertion protrusion 52 have the same predetermined cross-section, which can be a D-shape, a trapezoid, a T-shape, a non-equilateral triangle, or a sector. By setting the predetermined cross-section to the aforementioned shapes, the slot 51 and the insertion protrusion 52 can achieve a unique mating state between the first rotary transmission member 20 and the second rotary transmission member 30 when mated.

[0054] like Figure 7 and Figure 8 As shown, when the slot 51 is provided on the first rotary transmission member 20 and the insertion protrusion 52 is provided on the second rotary transmission member 30, the cross-sectional area of ​​the slot 51 gradually increases from bottom to top. The shape of the insertion protrusion 52 matches the shape of the slot 51, that is, the cross-sectional area of ​​the insertion protrusion 52 gradually increases from bottom to top, so as to facilitate the alignment of the insertion protrusion 52 and the slot 51. At the same time, the slot 51 and the insertion protrusion 52 have sidewalls extending in the oblique direction, which can serve as a guide and facilitate the insertion and mating of the insertion protrusion 52 and the slot 51.

[0055] like Figure 3 and Figure 10 As shown, the drive assembly further includes a first locking member 71 disposed on the pot body 1. When the lid assembly 2 is separated from the pot body 1, the first locking member 71 locks the lower drive structure. The first locking member 71 can lock the position of the upper and lower drive structures when the lid is open, thereby maintaining the first rotary transmission member 20 in a specific position, ensuring the effective docking of the second rotary transmission member 30 with the first rotary transmission member 20 during the lid closing process, and the offset between the lid teeth and the pot teeth.

[0056] like Figure 4 and Figure 10As shown, the drive assembly further includes a second locking member 72 disposed on the lid assembly 2. When the lid assembly 2 is separated from the pot body 1, the second locking member 72 locks the upper drive structure. The second locking member 72 can lock the position of the upper drive structure in the lid-open state, thereby maintaining the second rotary transmission member 30 and the locking member 3 in a specific position, ensuring the docking effect of the second rotary transmission member 30 and the first rotary transmission member 20 during the lid-closing process, and the offset arrangement between the lid teeth and the pot teeth.

[0057] like Figure 2 、 Figure 10 、 Figure 12 and Figure 13 As shown, the first rotary transmission member 20 includes a lower gear 21 and a lower coupling member 22 that are connected to each other in a rotationally fixed manner. The pot body 1 has a lower transmission cylinder 101. The lower coupling member 22 is disposed within the lower transmission cylinder 101 from top to bottom and engages with a stopper on the upper surface of the lower transmission cylinder 101. The lower gear 21 is disposed within the lower transmission cylinder 101 from bottom to top and engages with a stopper on the lower surface of the lower transmission cylinder 101. The first rotary transmission member 20 is configured as a separate lower gear 21 and lower coupling member 22, and the lower coupling member 22 and lower gear 21 respectively engage with the upper and lower surface stops of the lower transmission cylinder 101. This prevents the first rotary transmission member 20 from being driven downward or pulled upward during the process of pressing down or lifting the cover assembly 2, thereby ensuring the installation stability of the first rotary transmission member 20.

[0058] Specifically, if Figure 2 As shown, the lower gear 21 and the lower coupling member 22 are connected in a rotation-proof manner via a rotation-proof plug-in structure.

[0059] like Figure 2 、 Figure 3 and Figure 10 As shown, the operating unit 10 includes an operating knob 11 extending outward from the pot body 1 and a translational transmission member 12 located within the pot body 1. Rotating the operating knob 11 drives the translational transmission member 12, which in turn drives the lower gear 21. The operating unit 10 includes the operating knob 11. Rotating the operating knob 11 switches the position of the locking member 3, making operation easy. The translational transmission member 12 is disposed between the operating knob 11 and the lower gear 21 and cooperates with both the operating knob 11 and the lower gear 21, converting rotation of the operating knob 11 about its horizontal axis into rotation of the lower gear 21 about its vertical axis.

[0060] A guide groove 124 is provided on the translation transmission member 12 , and a guide post provided on the middle plate 103 can extend into the guide groove 124 to guide the movement of the translation transmission member 12 .

[0061] like Figure 1 and Figure 3As shown, the first locking member 71 includes a main plate 713, a first trigger portion 711 disposed above the main plate 713, a lock hook portion 712 disposed below the main plate 713, and an elastic member. The lock hook portion 712 has a slot 715 opening upward. The main plate 713 is provided with a guide hole 714. The middle plate 103 is provided with a guide post extending through the guide hole 714, allowing the first locking member 71 to be movably disposed in the vertical direction. The elastic member is sleeved on the guide post and upwardly presses against the first locking member 71. The translation transmission member 12 is provided with a lock rod 123. When the cover assembly 2 is not covered on the pot body 1, the elastic member pushes upward against the first locking member 71, causing the first trigger portion 711 to extend upward from the middle plate 103, and the lock hook portion 712 hooks the locking rod 123 and restricts the locking rod 123 from moving in the lateral direction, that is, restricts the translation transmission member 12 from moving in the lateral direction; when the cover assembly 2 is covered on the pot body 1, the cover assembly 2 presses down the first trigger portion 711 and overcomes the pushing force of the elastic member, causing the first locking member 71 to move downward as a whole, that is, the slot 715 moves to the bottom of the locking rod 123, so that the translation transmission member 12 can move in the lateral direction.

[0062] like Figure 1 and Figure 3 As shown, the operating knob 11 includes a knob body 111 and a transmission rod 112 disposed on the knob body 111. The transmission rod 112 extends toward the interior of the pot body 1 and is disposed offset from the center of the knob body 111. The translational transmission member 12 is provided with a mating groove 121, and the transmission rod 112 is disposed within the mating groove 121 to drive the translational transmission member 12 to move. The transmission rod 112 is disposed offset from the center of the knob body 111, so that when a user rotates the knob body 111, the movement trajectory of the transmission rod 112 is an arcuate trajectory or a circular trajectory centered on the axis of the knob body 111. The transmission rod 112 is inserted into the mating groove 121 on the translational transmission member 12, thereby driving the translational transmission member 12 to move.

[0063] like Figures 1 to 3 As shown, the translation transmission member 12 is provided with a lower driving tooth 122, and the lower gear 21 is provided with a lower driven tooth 211 that meshes with the lower driving tooth 122. The meshing between the lower driving tooth 122 and the lower driven tooth 211 enables the translation transmission member 12 to drive the first rotary transmission member 20 to rotate, which has the advantages of simple structure and reliable transmission.

[0064] like Figure 2 、 Figure 10 、 Figure 11 and Figure 13As shown, the second rotary transmission member 30 includes an upper gear 31 and an upper coupling member 32 that are connected to each other in a rotationally fixed manner. An upper transmission cylinder 201 is provided on the cover assembly 2. The upper gear 31 is inserted into the upper transmission cylinder 201 from top to bottom and engages with a stopper on the upper surface of the upper transmission cylinder 201. The upper coupling member 32 is inserted into the upper transmission cylinder 201 from bottom to top and engages with a stopper on the lower surface of the upper transmission cylinder 201. Providing the second rotary transmission member 30 with a separate upper gear 31 and upper coupling member 32, and with the upper gear 31 and upper coupling member 32 respectively engaging with the upper and lower stops on the upper transmission cylinder 201, can prevent the second rotary transmission member 30 from moving upward or downward when the cover assembly 2 is pressed down or lifted, thereby ensuring the installation stability of the second rotary transmission member 30.

[0065] Specifically, if Figure 2 As shown, the upper gear 31 and the upper coupling member 32 are connected in a non-rotatable manner via a non-rotatable plug-in structure.

[0066] The above is a description of the first embodiment of the drive component of the present application. The present application also provides various embodiments of the drive component. The following mainly describes the parts of other embodiments that are different from the first embodiment, and the same parts are not repeated.

[0067] Figure 6 The figure shows an exploded schematic diagram of the lower coupling member of the second embodiment of the drive assembly according to the present application. In this embodiment, a friction transmission structure 60 is disposed between the first rotating transmission member 20 and the second rotating transmission member 30. The friction transmission structure 60 includes a first friction member 61 and a second friction member that engage in a friction-locking manner. The first friction member 61 is disposed on the first rotating transmission member 20, and the second friction member is disposed on the second rotating transmission member 30. That is, in this embodiment, the frictional engagement between the first friction member 61 and the second friction member enables the second rotating transmission member 30 to rotate synchronously with the first rotating transmission member 20.

[0068] Specifically, if Figure 6 As shown, the upper end of the lower coupling member 22 of the first rotary transmission member 20 has a mounting groove, and the first friction member 61 is disposed in the mounting groove.

[0069] Figure 7 and Figure 8 FIG. 3 shows a schematic diagram of the three-dimensional structure of the upper coupling member and the lower coupling member of the third embodiment of the drive assembly according to the present application. In this embodiment, the predetermined cross-sections of the slot 51 and the plug-in protrusion 52 are isosceles triangles.

[0070] Figure 9A schematic diagram of the three-dimensional structure of the upper gear of the fourth embodiment of the drive assembly according to the present application is shown. In this embodiment, the lower end of the upper gear 31 is provided with multiple coupling protrusions 312. The upper gear 31 can achieve synchronous rotation with the upper coupling member 32 by plugging the multiple coupling protrusions 312 into the multiple coupling grooves on the upper coupling member 32. Alternatively, the upper gear 31 can achieve frictional rotation prevention with the rough upper end surface of the upper coupling member 32 by frictionally locking the multiple coupling protrusions 312, thereby achieving synchronous rotation with the upper gear 31 and the upper coupling member 32.

[0071] like Figures 10 to 16 As shown, the present application also provides a cooking utensil. An embodiment of the cooking utensil of the present application includes a pot body 1, a cover assembly 2 that can be opened and closed to cover the pot body 1, and a driving assembly arranged between the pot body 1 and the cover assembly 2, wherein the driving assembly is the above-mentioned driving assembly, wherein the cover assembly 2 includes a locking member 3, the locking member 3 is a locking cover, the locking member 3 includes a cover body 301 and a guide column 302 arranged on the cover body 301, the driving part 40 includes a rocker arm 41, the rocker arm 41 is provided with a rotating hole 42, a transmission hole 43 and a driving matching part 44, the guide column 302 is passed through the transmission hole 43, the second rotating transmission member 30 is driven and matched with the driving matching part 44, and when the second rotating transmission member 30 rotates, it drives the rocker arm 41 to swing with the axis of the rotating hole 42 as the rotation center to drive the guide column 302 to swing. The above-mentioned driving assembly can effectively solve the problems in the related art that the setting position of the control panel is inappropriate or the area of ​​the control panel is small, which affects the user experience. The cooking appliance with the above-mentioned driving assembly also has the above-mentioned advantages.

[0072] Specifically, if Figure 10 As shown, the pot body 1 includes a housing 102, a middle plate 103 disposed above the housing 102, a bottom shell 104 disposed below the housing 102, and a pot body 105 disposed within the mounting space formed by the housing 102, the middle plate 103, and the bottom shell 104. Pot teeth are formed on the pot body 105. The housing 102 is provided with a mounting opening 1021. The pot body 1 also includes a mounting seat 106 disposed at the mounting opening 1021. The operating knob 11 is mounted on the housing 102 via the mounting seat 106. The lower transmission cylinder 101 is disposed on the middle plate 103. Specifically, the middle plate 103 is provided with a transmission protrusion 108 that can extend below the upper transmission cylinder 201. The lower transmission cylinder 101 is disposed on the transmission protrusion 108.

[0073] like Figure 10 As shown, the cover assembly 2 includes a mounting cover 202 and a surface cover 204 disposed above the mounting cover 202. The locking member 3 is a locking cover rotatably disposed below the mounting cover 202. The upper transmission cylinder 201 is disposed on the mounting cover 202. Figure 11As shown, a mounting support 205 is provided on the mounting cover 202. The mounting support 205 is supported below the rocker arm 41 and extends through the rotation hole 42, allowing the rocker arm 41 to swing about the axis of the mounting support 205. The transmission hole 43 is located near the upper driven tooth 441. This arrangement allows the rocker arm 41 to swing at a relatively small angle to drive the locking member 3 to switch between the locked and unlocked positions.

[0074] In this embodiment, the locking member 3 is a locking cover that rotates to switch between a locked position and an unlocked position. The mounting cover 202 is provided with an arcuate slot 203. A guide post 302 extends from bottom to top through the arcuate slot 203 and into the transmission hole 43. The transmission hole 43 is a long slot extending along the length of the rocker 41.

[0075] Of course, in an embodiment not shown in the figures, the locking member may also be a caliper structure, in which case the locking member translates to switch between a locked position and an unlocked position.

[0076] In addition to the locking between the pot teeth and the cover teeth, the pot body 1 and the cover assembly 2 also have a locking structure with a hook structure. Figure 10 as well as Figures 13 to 15As shown, an upper hook 81 is fixedly mounted on the lid assembly 2, and a lower hook 82 is swingably mounted on the pot body 1. The lower hook 82 comprises a pivot portion 821, a hook body 822, and a push-up portion 823. The pivot portion 821 is hingedly connected to the middle plate 103, and the hook body 822 and the push-up portion 823 are respectively disposed on either side of the pivot portion 821. The hook body 822 is capable of engaging with the upper hook 81. During the swinging process, the lower hook 82 can switch between an engaged position, in which it engages with the upper hook 81, and an unengaged position, in which it is separated from the upper hook 81. A retaining member is also provided on the pot body 1, which applies a force to the lower hook 82 to maintain the lower hook 82 in the engaged position. When closing the lid, the upper hook 81 pushes against the hook body 822, causing the lower hook 82 to overcome the force of the retaining member and switch from the engaged position to the unengaged position. After the upper hook 81 passes over the hook body 822, the lower hook 82 returns from the unengaged position to the engaged position under the force of the retaining member, achieving automatic engagement between the upper hook 81 and the lower hook 82 during the lid closing process. When the lid needs to be opened, the user rotates the operating knob 11, and the transmission rod 112 on the operating knob 11 pushes against the push-top portion 823, causing the lower hook 82 to overcome the force of the retaining member and switch from the engaged position to the unengaged position. Specifically, the pushing top portion 823 is provided with an avoidance concave surface 8231 and a pushing inclined surface 8232 located below the avoidance concave surface 8231. In the direction from top to bottom, the pushing inclined surface 8232 extends toward the outside of the shell 102. When the transmission rod 112 corresponds to the avoidance concave surface 8231, there is a certain distance between the transmission rod 112 and the avoidance concave surface 8231. At this time, the transmission rod 112 will not push the lower hook 82; when the transmission rod 112 corresponds to the pushing inclined surface 8232, the transmission rod 112 can push the pushing top portion 823 to drive the lower hook 82 to swing, thereby realizing the disengagement between the lower hook 82 and the upper hook 81. By providing an avoidance concave surface 8231 and a pushing inclined surface 8232 on the pushing top portion 823, the pushing top portion 823 can avoid part of the stroke of the transmission rod 112, that is, the operation of first stripping and then releasing between the pot body 1 and the cover body assembly 2 can be realized. During this process, the user only needs to turn the operating knob 11, which simplifies the user's operating steps and improves the user experience.

[0077] like Figure 14 and Figure 16 As shown, an arc-shaped guide groove 1061 is provided on the mounting seat 106 , and the transmission rod 112 of the operating knob 11 is passed through the arc-shaped guide groove 1061 . The arc-shaped guide groove 1061 can guide and limit the rotation of the transmission rod 112 .

[0078] like Figure 1 and Figure 3As shown, the mating groove 121 of the translational transmission member 12 has a linkage section 1211 and an avoidance section 1212 arranged below the linkage section 1211. When the transmission rod 112 is located in the linkage section 1211, the transmission rod 112 can resist the side wall of the linkage section 1211 and drive the translational transmission member 12 to move; when the transmission rod 112 is located in the avoidance section 1212, the avoidance section 1212 can avoid the trajectory of the transmission rod 112, that is, the transmission rod 112 can continue to rotate but the translational transmission member 12 will not move.

[0079] Specifically, the linkage section 1211 is provided corresponding to the avoidance concave surface 8231 on the lower clasp 82, and the avoidance section 1212 is provided corresponding to the push-up inclined surface 8232 on the lower clasp 82. Through the above-mentioned arrangement, when the transmission rod 112 is located in the linkage section 1211, the transmission rod 112 and the translation transmission member 12 drive and cooperate to drive the translation transmission member 12 to move, the transmission rod 112 is provided corresponding to the avoidance concave surface 8231 and cannot drive the lower clasp 82, at this time, the tooth removal operation can be performed, and the lower clasp 82 remains in the engaged position; when the transmission rod 112 is located in the avoidance section 1212, the transmission rod 112 and the push-up inclined surface 8232 drive and cooperate to drive the lower clasp 82 from the engaged position to the unfastened position, the transmission rod 112 cannot drive the translation transmission member 12 to move, and at this time, the release operation can be performed.

[0080] like Figure 10 and Figure 14 As shown, the pot body 1 further includes a reset member 107 disposed between the mounting base 106 and the operating knob 11. When the lid opening operation is completed and the user no longer operates the operating knob 11, the reset member 107 applies a reset force to the transmission rod 112, causing the transmission rod 112 to move from the avoidance section 1212 to the linkage section 1211. At this time, the transmission rod 112 no longer presses against the push-up inclined surface 8232, causing the lower hook 82 to return to the engaged position. When the user subsequently closes the lid, the upper hook 81 and the lower hook 82 can be automatically engaged.

[0081] like Figure 10 and Figure 14 As shown, a sinking portion 1062 is further provided in the mounting seat 106, and the reset member 107 is a torsion spring installed in the sinking portion 1062. The sinking portion 1062 is connected to a portion of the arc-shaped guide groove 1061. When the transmission rod 112 is located in the linkage section 1211, the two torsion arms of the torsion spring respectively abut the two side surfaces of the sinking portion 1062, and the torsion spring does not apply a force to the transmission rod 112. When the transmission rod 112 is located in the avoidance section 1212, one torsion arm of the torsion spring abuts a side wall of the sinking portion 1062, and the other torsion arm abuts the transmission rod 112, so that the transmission rod 112 has a tendency to reset into the linkage section 1211.

[0082] Specifically, if Figure 2 、 Figure 4 、 Figure 5 and Figure 10 As shown, the upper gear 31 of the second rotating transmission member 30 is provided with an upper driving tooth 311, and the driving matching part 44 is provided with an upper driven tooth 441 that can engage with the upper driving tooth 311. When the second rotating transmission member 30 rotates, the engagement between the upper driving tooth 311 and the upper driven tooth 441 is used to drive the rocker arm 41 to swing.

[0083] like Figure 1 、 Figure 4 and Figure 5 As shown, the second locking member 72 includes a second trigger portion 721, a mounting tube 722, an elastic member 723, a cantilever 724 and a locking block 725. The second trigger portion 721 and the mounting tube 722 are arranged side by side. The mounting tube 722 has an upper opening. The elastic member 723 is arranged in the mounting tube 722 and applies a downward push force to the mounting tube 722. The cantilever 724 is connected to the upper end of the second trigger portion 721. The locking block 725 is arranged below the cantilever 724. A locking hole 45 is provided on the rocker arm 41. When the cover assembly 2 is not covered on the pot body 1, the second trigger part 721 extends downward from the installation cover 202 under the action of the elastic member 723, and the locking block 725 is inserted into the locking hole 45 to limit the swing of the rocker 41; when the cover assembly 2 is covered on the pot body 1, the pot body 1 pushes the second trigger part 721 upward, so that the second locking member 72 moves upward as a whole and overcomes the resisting force of the elastic member 723, and the locking block 725 disengages from the locking hole 45 upward, and the rocker 41 can swing.

[0084] In the description of the present invention, it needs to be understood that the directions or positional relationships indicated by directional words such as "front, back, up, down, left, right", "horizontal, vertical, vertical, horizontal" and "top, bottom" are usually based on the directions or positional relationships shown in the drawings. They are only for the convenience of describing the present invention and simplifying the description. Unless otherwise specified, these directional words do not indicate or imply that the device or element referred to must have a specific direction or be constructed and operated in a specific direction. Therefore, they cannot be understood as limiting the scope of protection of the present invention; the directional words "inside and outside" refer to the inside and outside relative to the outline of each component itself.

[0085] For ease of description, spatially relative terms such as "above", "above", "on the upper surface of", "above", etc. may be used herein to describe the spatial positional relationship of a device or feature to other devices or features as shown in the figures. It should be understood that spatially relative terms are intended to include different orientations of the device in use or operation in addition to the orientation described in the figures.
