Utility Model Content

[0004] The main purpose of the present invention is to provide a cover assembly and a cooking utensil having the same, so as to solve the problem of complex structure of the cover assembly in the related art.

[0005] In order to achieve the above-mentioned purpose, according to one aspect of the utility model, a cover assembly is provided, including: a locking cover, which is rotatably arranged and has a locking position and an unlocking position, and a linkage column is provided on the locking cover; an exhaust assembly, including an exhaust pipe and a pressure-limiting valve movably arranged above the exhaust pipe; a cover-opening pendulum, the first end of the cover-opening pendulum is rotatably mounted on the exhaust pipe, the second end of the cover-opening pendulum is a driving mating end, a linkage hole is provided on the cover-opening pendulum, the linkage column is passed through the linkage hole, and when the cover-opening pendulum swings, the locking cover is driven to rotate through the linkage column.

[0006] By applying the technical solution of the present invention, the locking cover can be rotatably arranged and can be switched between a locked position and an unlocked position. When the locking cover is in the locked position, the locking cover can be locked and matched with the pot body assembly to bear pressure; when the locking cover is in the unlocked position, the lid opening operation and the lid closing operation can be realized. The lid opening pendulum can be swingably arranged, the first end of the lid opening pendulum is sleeved on the exhaust pipe, the second end of the lid opening pendulum is a driving matching end and can be driven by the driving structure to realize the lid opening pendulum swinging around the exhaust pipe, and the lid opening pendulum drives the locking cover to rotate and switch positions when it swings. Among them, the exhaust pipe can be used to discharge high-pressure gas and can also be used to install and position the lid opening pendulum, realizing the reuse of the exhaust pipe without the need to set up an additional structure inside the cover body assembly to install and guide the movement of the lid opening pendulum, thereby simplifying the structure of the cover body assembly. Therefore, the technical solution of the present application can effectively solve the problem of complex structure of the cover body assembly in the related art.

[0007] Furthermore, a rotating cylinder is provided at the first end of the lid opening ornament, and the rotating cylinder is sleeved on the exhaust pipe. The rotating cylinder increases the connection area between the lid opening ornament and the exhaust pipe, thereby enabling the lid opening ornament to be more stably connected to the exhaust pipe.

[0008] Furthermore, a driven arc tooth is provided at the second end of the cover opening rocker, which can mesh with the driving tooth structure to drive the cover opening rocker, thereby enabling the cover opening rocker to swing and drive the locking cover to switch positions.

[0009] Furthermore, the cover assembly includes an upper drive member, which includes an upper drive gear that meshes with the driven arc teeth to drive the cover-opening swing member to swing. When the upper drive gear rotates, it can drive the cover-opening swing member to swing through the meshing with the driven arc teeth, thereby having the advantages of simple structure and reliable drive.

[0010] Furthermore, a retaining ring is provided on the exhaust pipe, and the lower end of the exhaust pipe is inserted into the locking cover. The retaining ring engages with a stopper on the upper surface of the locking cover. The exhaust assembly also includes a locking nut provided at the lower end of the exhaust pipe, which locks the exhaust pipe to the locking cover.

[0011] Furthermore, the cover assembly further includes a mounting cover, a locking cover disposed below the mounting cover, a cover-opening swing member disposed above the mounting cover, and a support rib disposed on the mounting cover, the support rib supporting the cover-opening swing member below. Furthermore, the exhaust assembly further includes a stopper disposed on the exhaust pipe, the stopper cooperating with a stopper on the upper surface of the cover-opening swing member to restrict the cover-opening swing member from upwardly disengaging from the exhaust pipe. The stopper and the mounting cover together limit the cover-opening swing member in the vertical direction, allowing the cover-opening swing member to swing only in the lateral direction and not in the vertical direction, thereby ensuring reliable transmission of the cover-opening swing member.

[0012] According to another aspect of the present invention, a cooking utensil is provided, comprising a cover assembly, wherein the cover assembly is the above-mentioned cover assembly. The above-mentioned cover assembly can effectively solve the problem of complex structure of the cover assembly in the related art, and the cooking utensil having the above-mentioned cover assembly also has the above-mentioned advantages.

[0013] According to another aspect of the present invention, a cooking utensil is provided, comprising a pot body assembly and a cover body assembly that can be opened and closed on the pot body assembly, wherein the cover body assembly is the above-mentioned cover body assembly; the pot body assembly comprises: a shell; an operating member disposed on the shell body and exposed outward from the shell body; a lower driving member disposed on the shell body and exposed upward from the shell body, the lower end of the lower driving member being driven and engaged with the operating member, and the upper end of the lower driving member being driven and engaged with the upper driving member. The driving force applied by the user to the operating member can be transmitted to the locking cover via the lower driving member, the upper driving member, and the lid opening pendant, thereby driving the locking cover to rotate. That is, the above-mentioned arrangement realizes that the operating member for the user to operate to open and close the lid is disposed on the pot body assembly, thereby completely freeing up the space above the cover body assembly to be used for arranging a larger interactive panel or other structure for user convenience.

[0014] Furthermore, the lid assembly further includes a first hook, and the pot assembly further includes a second hook. The second hook is movably disposed on the housing and has an engaged position in which it engages with the first hook and a disengaged position in which it is separated from the first hook. The operating member drives and cooperates with the second hook to drive the second hook to switch from the engaged position to the disengaged position. The locking engagement between the locking lid and the pot assembly, as well as the engagement between the first hook and the second hook, enables dual locking of the lid assembly and the pot assembly, thereby preventing rigid collision between the cover teeth of the locking lid and the pot teeth of the pot assembly under the action of the lid opening torsion spring during the lid opening and closing process.

[0015] Furthermore, the operating member is rotatably disposed on the housing and has a first operating position, a second operating position, and a third operating position that are sequentially disposed. When the operating member is between the first operating position and the second operating position, the operating member is driven to cooperate with the lower driving member and is separated from the second hook. When the operating member is between the second operating position and the third operating position, the operating member is driven to cooperate with the second hook and is separated from the lower driving member. When the operating member is located between the first operating position and the second operating position, the operating member is driven to cooperate with the lower driving member but not with the second hook, thereby only driving the locking cover to switch positions without driving the second hook to switch positions. When the operating member is located between the second operating position and the third operating position, the operating member is driven to cooperate with the second hook but not with the lower driving member, thereby only driving the second hook to switch positions without driving the locking cover to switch positions, thereby achieving separate driving of the locking cover and the second hook.

[0035] 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.

In all examples shown and discussed here, any specific value should be interpreted as being merely exemplary, rather than as a limitation. Therefore, other examples of the exemplary embodiments may have different values. 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.

[0038] like Figures 1 to 4 As shown, the present application provides a cover assembly, and an embodiment of the cover assembly of the present application includes: a locking cover 10, an exhaust assembly 20, and a cover opening pendulum 30. Among them, the locking cover 10 is rotatably arranged and has a locked position and an unlocked position, and a linkage column 11 is provided on the locking cover 10; the exhaust assembly 20 includes an exhaust pipe 21 and a pressure-limiting valve 22 movably provided above the exhaust pipe 21; the cover opening pendulum 30 has a first end rotatably sleeved on the exhaust pipe 21, and a second end of the cover opening pendulum 30 is a driving mating end. The cover opening pendulum 30 is provided with a linkage hole 31, and the linkage column 11 is inserted into the linkage hole 31. When the cover opening pendulum 30 swings, it drives the locking cover 10 to rotate through the linkage column 11.

[0039] Using the technical solution of this embodiment, the locking cover 10 is rotatably configured and can be switched between a locked position and an unlocked position. When in the locked position, the locking cover 10 locks with the pot body assembly 60 to withstand pressure. When in the unlocked position, the lid can be opened and closed. The lid-opening rocker 30 is swingably configured. The first end of the rocker 30 is sleeved onto the exhaust pipe 21, and the second end of the rocker 30 is a driving engagement end that can be driven by a driving structure to swing the rocker 30 around the exhaust pipe 21. The swinging of the rocker 30 drives the locking cover 10 to rotate and switch positions. The exhaust pipe 21 can be used to both exhaust high-pressure gas and to install and position the rocker 30, enabling the reuse of the rocker 30. This eliminates the need for additional internal structure within the lid assembly to install and guide the movement of the rocker 30, simplifying the lid assembly structure. Therefore, the technical solution of this embodiment effectively solves the problem of complex lid assembly structure in related technologies.

[0040] like Figure 1 and Figure 2 As shown, the locking cover 10 includes a cover body 12 and a cover tooth 13 arranged on the cover body 12, and a linkage column 11 is arranged on the cover body 12. When the locking cover 10 is in the locked position, the cover tooth 13 is located directly below the pot tooth on the pot body assembly 60, thereby realizing pressure bearing during pressure cooking; when the locking cover 10 is in the unlocked position, the cover tooth 13 is staggered with the pot tooth, so that the cover can be opened and closed.

[0041] like Figures 3 to 6 as well as Figure 8 As shown, a rotating cylinder 32 is provided at the first end of the lid opening rocker 30, and the rotating cylinder 32 is sleeved on the exhaust pipe 21. The rotating cylinder 32 has a certain height, which increases the connection area between the lid opening rocker 30 and the exhaust pipe 21, thereby ensuring a more stable connection between the lid opening rocker 30 and the exhaust pipe 21.

[0042] like Figure 3 、 Figure 4 and Figure 8 The second end of the cover opening rocker 30 is provided with a driven arc tooth 33. The driven arc tooth 33 can mesh with the driving tooth structure to drive the cover opening rocker 30, thereby enabling the cover opening rocker 30 to swing and drive the locking cover 10 to switch positions.

[0043] Specifically, if Figure 8 As shown, the cover opening rocker 30 includes a swing rod 34 , a rotating cylinder 32 is arranged at a first end of the swing rod 34 , a driven arc tooth 33 is arranged at a second end of the swing rod 34 , and a linkage hole 31 is arranged on the swing rod 34 .

[0044] like Figure 1 、 Figure 3 and Figure 4 As shown in Figure 4 , the lid assembly of this embodiment is the lid assembly of a square cooker. The exhaust assembly 20 is arranged at the central position of the lid assembly. The driven arc gear 33 extends radially out of the locking lid 10 along the lid assembly. When the open - lid swing member 30 is driven to swing, it takes the center line of the locking lid 10 as the swing center, so that the length of the driving force arm for driving the open - lid swing member 30 to swing is relatively long, enabling the locking lid 10 to be rotated by the open - lid swing member 30 with a relatively small force.

[0045] As Figure 1 and Figures 3 to 5 As shown in Figures 3 to 5 , the lid assembly further includes an upper driving member 40. The upper driving member 40 includes an upper driving gear 41. The upper driving gear 41 meshes with the driven arc gear 33 to drive the open - lid swing member 30 to swing. When the upper driving gear 4 rotates, it can drive the open - lid swing member 30 to swing through meshing with the driven arc gear 33, which has the advantages of simple structure and reliable driving.

[0046] As Figure 5 and Figure 6 As shown in Figure 6 , a retaining ring 211 is provided on the exhaust pipe 21. The lower end of the exhaust pipe 21 penetrates through the locking lid 10. The retaining ring 211 is in stop fit with the upper surface of the locking lid 10. The exhaust assembly 20 further includes a locking nut 23 provided at the lower end of the exhaust pipe 21. The locking nut 23 locks the exhaust pipe 21 to the locking lid 10. By providing the retaining ring 211 and the locking nut 23, the exhaust pipe 21 can be stably installed on the locking lid 10, ensuring the position stability of the exhaust pipe 21, and further ensuring the position stability of the first end of the open - lid swing member 30 sleeved on the exhaust pipe 21.

[0047] As Figure 6 As shown in Figure 6 , in this embodiment, the lid assembly further includes a sealing structure (not shown in the figure) sleeved on the exhaust pipe 21 and clamped between the locking lid 10 and the locking nut 23. The connection between the exhaust pipe 21 and the locking lid 10 can be sealed through the sealing structure.

[0048] As Figures 3 to 5 [[ID=2 =7]]and Figure 7As shown, the lid assembly also includes a mounting cover 50, a locking cover 10 disposed below the mounting cover 50, and a lid-opening rocker 30 disposed above the mounting cover 50. The mounting cover 50 is provided with support ribs 51, which support the lid-opening rocker 30 from below. The mounting cover 50 directly supports the lid-opening rocker 30, eliminating the need for additional internal structure within the lid assembly to mount and guide the movement of the lid-opening rocker 30, thereby simplifying the structure of the lid assembly. Because the lid-opening rocker 30 is swingably disposed above the mounting cover 50, the support ribs 51 provided on the mounting cover 50 not only provide support for the lid-opening rocker 30, but also reduce the contact area between the lid-opening rocker 30 and the mounting cover 50, thereby facilitating smoother movement of the lid-opening rocker 30.

[0049] like Figures 2 to 5 As shown, a guide arc hole 52 is provided on the mounting cover 50 , and the linkage column 11 is upwardly passed through the guide arc hole 52 and extends into the linkage hole 31 of the cover opening ornament 30 .

[0050] In this embodiment, the exhaust assembly 20 further includes a stopper positioned on the exhaust pipe 21. This stopper cooperates with a stopper on the upper surface of the lid-opening rocker 30 to prevent the lid-opening rocker 30 from disengaging from the exhaust pipe 21. Specifically, the stopper may be a collar that fits over the exhaust pipe 21 and is secured to the exhaust pipe 21 via screws. Together, the stopper and the mounting cap 50 limit the vertical position of the lid-opening rocker 30, allowing it to swing only in the lateral direction and preventing vertical movement, thus ensuring reliable transmission of the lid-opening rocker 30.

[0051] like Figure 1 As shown, the cover assembly further includes a face cover 70 disposed above the mounting cover 50 .

[0052] like Figure 9 and Figure 10 As shown, the present application also provides a cooking utensil. An embodiment of the cooking utensil of the present application includes a cover assembly, wherein the cover assembly is the above-mentioned cover assembly. The above-mentioned cover assembly can effectively solve the problem of complex structure of the cover assembly in the related art, and the cooking utensil with the above-mentioned cover assembly also has the above-mentioned advantages.

[0053] like Figure 9 and Figure 10As shown, the present application also provides a cooking utensil. An embodiment of the cooking utensil of the present application includes a pot body assembly 60 and a cover body assembly that can be opened and closed on the pot body assembly 60, wherein the cover body assembly is the above-mentioned cover body assembly; the pot body assembly 60 includes: a shell 61, an operating member 62 and a lower driving member 63, wherein the operating member 62 is arranged on the shell 61 and exposed outwardly from the shell 61; the lower driving member 63 is arranged on the shell 61 and exposed upward from the shell 61, the lower end of the lower driving member 63 is drivingly engaged with the operating member 62, and the upper end of the lower driving member 63 is drivingly engaged with the upper driving member 40.

[0054] It should be noted that the aforementioned "operating member 62 is exposed outside the housing 61" is not limited to the operating member 62 extending outside the housing 61. In an embodiment not shown in the figures, the operating member may not protrude from the housing. In this case, an operating recess is provided on the housing for the user to insert his hand into to operate the operating member.

[0055] Applying the technical solution of this embodiment, the pot body assembly 60 includes an operating member 62 and a lower driving member 63. The upper and lower ends of the lower driving member 63 are respectively driven by the upper driving member 40 and the operating member 62. The user can operate the operating member 62 set on the shell 61. The driving force applied by the user to the operating member 62 can be transmitted to the locking cover 10 via the lower driving member 63, the upper driving member 40 and the lid opening pendant 30, thereby driving the locking cover 10 to rotate. That is, the above-mentioned arrangement realizes that the operating member 62 for the user to operate to open and close the lid is set on the pot body assembly 60, and the space above the lid assembly can be completely vacated to be used to set a larger interactive panel or other structure for user convenience.

[0056] like Figure 9 As shown, the shell 61 includes an outer shell 611, a middle plate 612 arranged above the outer shell 611, and a bottom shell 613 arranged below the outer shell 611. The pot body assembly 60 also includes a pot body 65 arranged in the shell 61 and a pressure ring 66 arranged on the inner side of the middle plate 612. The pressure ring 66 is provided with pot teeth that can engage with the cover teeth 13 to bear pressure.

[0057] like Figure 1 、 Figure 5 、 Figure 9 and Figure 10As shown, the upper driving member 40 includes an upper coupling column 42 and an upper driving gear 41 fixedly connected to the upper coupling column 42, and the lower driving member 63 includes a transmission slide 633, a lower driving gear 631 and a lower coupling column 632, wherein the transmission slide 633 is movably arranged in the transverse direction, and when the operating member 62 rotates, it can drive the transmission slide 633 to move, and a driving rack is provided on the transmission slide 633, and the lower driving gear 631 is engaged with the driving rack. When the transmission slide 633 translates, it drives the lower driving gear 631 to rotate, and the lower coupling column 632 is fixedly connected Above the lower drive gear 631, the lower coupling post 632 rotates synchronously with the lower drive gear 631. When the lid assembly is placed on the pot assembly 60, the lower coupling post 632 and the upper coupling post 42 are locked and coupled. This means that the upper coupling post 42 and the upper drive gear 41 rotate synchronously with the lower coupling post 632 and the lower drive gear 631. Rotation of the upper drive gear 41, through engagement with the driven arc teeth 33, drives the lid-opening rocker 30 to swing, thereby rotating the locking lid 10 to switch between the locked and unlocked positions. This structure allows the driving force applied by the user to the operating member 62 on the pot assembly 60 to be transmitted step by step through the lower drive member 63, the upper drive member 40, and the lid-opening rocker 30 to the locking lid 10, driving the locking lid 10 to switch positions.

[0058] like Figure 9 and Figure 10 As shown, the lid assembly also includes a first hook, and the pot assembly 60 also includes a second hook 64. The second hook 64 is movably disposed on the housing 61 and has an engaged position in which it engages with the first hook and a disengaged position in which it is separated from the first hook. The operating member 62 drives and cooperates with the second hook 64 to move the second hook 64 from the engaged position to the disengaged position. The locking engagement between the locking lid 10 and the pot assembly 60 and the engagement between the first hook and the second hook 64 enable dual locking between the lid assembly and the pot assembly 60. This allows the first hook and the second hook 64 to engage during closing, and then lock the locking lid 10 and the pot assembly 60. During opening, the locking between the locking lid 10 and the pot assembly 60 is first released, and then the engagement between the first hook and the second hook 64 is released. This prevents the lid teeth 13 on the locking lid 10 and the pot teeth on the pot assembly 60 from rigidly colliding due to the lid opening torsion spring.

[0059] Specifically, in this embodiment, the operating member 62 is rotatably provided on the shell 61 and has a first operating position, a second operating position and a third operating position arranged in sequence. When the operating member 62 is between the first operating position and the second operating position, the operating member 62 is driven to cooperate with the lower driving member 63 and is separated from the second hook 64. When the operating member 62 is between the second operating position and the third operating position, the operating member 62 is driven to cooperate with the second hook 64 and is separated from the lower driving member 63. The operating member 62 has a first operating position, a second operating position and a third operating position which are arranged in sequence, and when the operating member 62 is located between the first operating position and the second operating position, the operating member 62 is driven and cooperated with the lower driving member 63 but not with the second hook 64, so that only the locking cover 10 is driven to switch positions without driving the second hook 64 to switch positions; when the operating member 62 is located between the second operating position and the third operating position, the operating member 62 is driven and cooperated with the second hook 64 but not with the lower driving member 63, so that only the second hook 64 is driven to switch positions without driving the locking cover 10 to switch positions, thereby realizing the separate driving of the locking cover 10 and the second hook 64.

[0060] like Figure 9 and Figure 10 As shown, the operating member 62 is a rotating operating member, which includes an operating knob 621 and a transmission rod 622 arranged on the operating knob 621. The transmission rod 622 is set away from the rotation center of the operating knob 621. A transmission groove 6331 is provided on the transmission slide 633. The transmission rod 622 is inserted into the transmission groove 6331. When the operating knob 621 is rotated, the transmission rod 622 moves in an arc trajectory and drives the transmission slide 633 to move in the lateral direction. The transmission groove 6331 includes a linkage groove section and an avoidance groove section arranged below the linkage groove section. When the operating member 62 switches between the first operating position and the second operating position, the transmission rod 622 is located in the linkage groove section of the transmission groove 6331 and can drive the transmission slide 633 to move, and then drive the locking cover 10 to switch positions through the lower drive gear 631, the lower coupling column 632, the upper coupling column 42, the upper drive gear 41 and the cover opening pendulum 30; when the operating member 62 switches between the second operating position and the third operating position, the transmission rod 622 is located in the avoidance groove section of the transmission groove 6331 and cannot drive the transmission slide 633 to move, so that the locking cover 10 remains in position unchanged.

[0061] like Figure 9 As shown, a mounting opening is provided on the housing 611 , and the shell 61 further includes a mounting seat 614 provided at the mounting opening. The operating member 62 is rotatably mounted on the housing 611 through the mounting seat 614 .

[0062] like Figure 9 and Figure 10As shown, the second hook 64 is a swinging hook, and the transmission rod 622 can push the second hook 64 to drive it to swing so that the second hook 64 switches from the engaged position to the disengaged position. The pot body assembly 60 also includes a reset torsion spring arranged between the shell 61 and the second hook 64. When the user no longer operates the operating member 62, the second hook 64 can switch from the disengaged position to the engaged position under the action of the reset torsion spring. The second hook 64 is provided with a mating surface 641, which includes an avoidance concave surface corresponding to the linkage groove section of the transmission groove 6331 and a transmission inclined surface corresponding to the avoidance groove section of the transmission groove 6331. When the operating member 62 switches between the first operating position and the second operating position, the transmission rod 622 corresponds to the avoidance concave surface and cannot drive the second hook 64. The second hook 64 remains in the engaged position under the action of the reset torsion spring; when the operating member 62 switches between the second operating position and the third operating position, the transmission rod 622 corresponds to the transmission inclined surface and cooperates with the transmission inclined surface. During the process of the operating member 62 rotating from the second operating position to the third operating position, the transmission rod 622 pushes the transmission inclined surface so that the second hook 64 overcomes the force of the reset torsion spring and swings, switching from the engaged position to the disengaged position.

[0063] Specifically, in this embodiment, when the operating member 62 is in the first operating position, the locking cover 10 is in the locking position and the second hook 64 is in the fastening position; when the operating member 62 is in the second operating position, the locking cover 10 is in the unlocking position and the second hook 64 is in the fastening position; when the operating member 62 is in the third operating position, the locking cover 10 is in the unlocking position and the second hook 64 is in the disengaging position.

[0064] 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.

[0065] 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. For example, if the device in the drawings is inverted, the device described as "above other devices or structures" or "above other devices or structures" will be positioned as "below other devices or structures" or "below other devices or structures". Thus, the exemplary term "above" can include both "above" and "below". The device can also be positioned in other different ways (rotated 90 degrees or in other orientations), and the spatially relative descriptions used here are interpreted accordingly.

[0066] In addition, it should be noted that the use of words such as "first" and "second" to limit components is only for the convenience of distinguishing the corresponding components. Unless otherwise stated, the above words have no special meaning and therefore cannot be understood as limiting the scope of protection of this utility model.

[0067] The above description is merely a preferred embodiment of the present invention and is not intended to limit the present invention. Those skilled in the art will readily appreciate that the present invention is susceptible to various modifications and variations. Any modifications, equivalent substitutions, or improvements made within the spirit and principles of the present invention shall be included within the scope of protection of the present invention.
