[0029] like Figure 1 , Figure 2 and Figure 4 As shown, the pot cover assembly in this embodiment includes: an upper cover assembly 10, an inner pot cover 20, a temperature measuring assembly 30 and a first sealing member 40. The upper cover assembly 10 includes an inner lining 12, and the inner lining 12 has a first through hole 11. The temperature measuring assembly 30 includes a mounting seat 31 and a temperature measuring column 32 inserted in the mounting seat 31, the mounting seat 31 is arranged on the upper cover assembly 10, and the temperature measuring column 32 passes through the first through hole 11. The inner pot cover 20 is detachably arranged below the upper cover assembly 10, and the inner pot cover 20 is provided with a second through hole 21 corresponding to the first through hole 11. The first sealing member 40 is connected in the second through hole 21, and the first sealing member 40 is provided with a third through hole 41 for the temperature measuring column 32 to pass through. Among them, when the inner pot cover 20 is separated from the upper cover assembly 10, the first sealing member 40 is separated from the upper cover assembly 10 and the temperature measuring assembly 30. When the inner pot cover 20 is assembled to the upper cover assembly 10 , the first sealing member 40 and the mounting seat 31 are sealed by the conical sealing surface, and the temperature measuring column 32 passes through the third through hole 41 .

[0030] The technical solution of this embodiment is applied, and the temperature measuring assembly 30 includes a mounting seat 31 and a temperature measuring column 32 inserted in the mounting seat 31. The mounting seat 31 is arranged on the upper cover assembly 10, and the temperature measuring column 32 passes through the first through hole 11 of the upper cover assembly 10. The first sealing member 40 is connected to the second through hole 21 of the inner pot cover 20, and the first sealing member 40 is provided with a third through hole 41 for the temperature measuring column 32 to pass through. In this embodiment, when the inner pot cover 20 is separated from the upper cover assembly 10, the first sealing member 40 is separated from the upper cover assembly 10 and the temperature measuring assembly 30. When the inner pot cover 20 is assembled to the upper cover assembly 10, the first sealing member 40 and the mounting seat 31 are sealed by a conical sealing surface, and the temperature measuring column 32 passes through the third through hole 41. The above-mentioned conical sealing surface has a guiding function, which facilitates the alignment between the first sealing member 40 and the mounting seat 31, so that the stability of the seal is guaranteed. When the pressure is increased in the pot, the inner pot cover 20 floats up, and the conical sealing surface makes the mounting seat 31 and the first sealing member 40 fit more and more tightly, thereby improving the sealing performance. At the same time, the first sealing member 40 can leave the upper cover assembly 10 and the temperature measuring assembly 30 along with the inner pot cover 20, so that it is easy to clean the first sealing member 40 and reduce the aging of the first sealing member 40.

[0031] like Figure 1 and Figure 2As shown, in this embodiment, a conical platform 33 is provided on the mounting seat 31, and a conical groove 42 cooperating with the conical platform 33 is provided on the first sealing member 40. The cooperation between the conical platform 33 and the conical groove 42 can ensure good sealing between the mounting seat 31 and the first sealing member 40, and is easy to implement. In other embodiments not shown in the figures, a conical groove is provided on the mounting seat, and a conical platform cooperating with the conical platform is provided on the first sealing member. In this way, good sealing between the mounting seat and the first sealing member can still be ensured. In this embodiment, the first sealing member 40 is preferably a silicone member, and the first sealing member 40 is elastic, has good sealing performance, and is also convenient for the installation of the first sealing member 40. The conical platform 33 and the conical groove 42 are in surface contact and cooperation, and the sealing area is larger and the sealing effect is better.

[0032] like Figure 1 and Figure 2 As shown, in this embodiment, the conical platform 33 is arranged on the mounting seat 31, the conical groove 42 is arranged on the first sealing member 40, and the third through hole 41 is arranged on the groove bottom of the conical groove 42. The conical platform 33 gradually shrinks and extends in the direction toward the inner pot cover 20. That is, the conical platform 33 is a structure with a large top and a small bottom. When the inner pot cover 20 floats under pressure in the pot, the conical platform 33 and the conical groove 42 will be more and more tightly matched, thereby making the sealing between the mounting seat 31 and the first sealing member 40 better.

[0033] like Figure 2 and Figure 3 As shown, in this embodiment, the busbar 331 of the conical platform 33 is a straight line, and the busbar 421 of the conical groove 42 is a straight line adapted to the busbar 331 of the conical platform 33. In this way, the conical platform 33 and the conical groove 42 are smoothly installed. In addition, the busbar 331 of the conical platform 33 and the busbar 421 of the conical groove 42 are both straight lines, which are also convenient for processing and molding. In other embodiments not shown in the figures, the busbar of the conical platform can also be a curve, and the busbar of the conical groove can also be a curve adapted to the busbar of the conical platform. The above structure can also achieve a close fit, thereby ensuring the sealing between the conical platform and the conical groove.

[0034] like Figure 2 and Figure 3 As shown, an annular groove 43 is provided on the outer side wall of the first sealing member 40, and the first sealing member 40 is installed at the second through hole 21 through the annular groove 43. In this embodiment, the annular groove 43 prevents the first sealing member 40 from being separated from the inner pot cover 20, so that the first sealing member 40 and the inner pot cover 20 are tightly installed.

[0035] like Figure 2 and Figure 3As shown, in this embodiment, the mounting seat 31 is provided with an annular surface 311 corresponding to the outer side of the conical platform in the circumferential direction, and the annular surface 311 cooperates with the top surface of the first sealing member 40. In this way, the provision of the annular surface 311 enables the mounting seat 31 to provide certain support to the first sealing member 40. In addition, the mounting seat 31 and the first sealing member 40 first achieve a first seal through the conical platform 33 and the conical groove 42, and the annular surface 311 cooperates with the top surface of the first sealing member 40 to achieve a second seal. In this way, the mounting seat 31 and the first sealing member 40 are double-coordinated, thereby improving the reliability of the seal.

[0036] like Figure 1 and Figure 2 As shown, the upper cover assembly 10 is also provided with a cover removal operation key. When the user triggers the cover removal operation key, the inner pot cover 20 is separated from the upper cover assembly 10. In this embodiment, the cover removal operation key can be a button structure or a touch button. A locking mechanism is provided in the upper cover assembly, which can keep the inner pot cover locked by an elastic member under normal conditions, and can move when the user presses the button structure or touches the touch button to unlock the inner pot cover. A buckle structure that cooperates with the locking mechanism can be provided on the inner pot cover. When the locking mechanism blocks the buckle structure, the inner pot cover is locked on the upper cover assembly. When the locking mechanism is separated from the buckle structure, the inner pot cover is unlocked and can leave the inner cover assembly. The cooperation method between the upper cover assembly and the inner pot cover belongs to the prior art, and is not limited to the above method. For details, reference can also be made to the content of the utility model patent with application number 201620341611.7.

[0037] like Figure 2 and Figure 3 As shown, a mounting groove 22 is provided on the surface of the inner pot cover 20 away from the upper cover assembly 10, the second through hole 21 is provided at the groove bottom of the mounting groove 22, and the first sealing member 40 is provided in the mounting groove 22. In this embodiment, the surface of the first sealing member 40 does not protrude from the lower surface of the inner pot cover 20. The above structure ensures that the first sealing member 40 does not affect the user's cleaning of the inner pot cover 20.

[0038] like Figure 2 and Figure 3 As shown, in this embodiment, the pot cover assembly further includes a second sealing member 50 disposed between the upper cover assembly 10 and the inner pot cover 20, the inner edge of the second sealing member 50 is disposed between the mounting seat 31 and the upper cover assembly 10, and the outer edge of the second sealing member 50 is disposed between the upper cover assembly 10 and the inner pot cover 20. The provision of the second sealing member 50 ensures the sealing effect between the upper cover assembly 10 and the mounting seat 31 and between the upper cover assembly 10 and the inner pot cover 20.

[0039] like Figure 2 and Figure 3As shown, the pot cover assembly also includes a connecting member 312 and a second sealing member 50, the connecting member 312 is located at the first through hole 11 and is connected to the upper cover assembly 10 in a floating manner, a fourth through hole 3121 is provided on the connecting member 312, the mounting seat 31 is arranged in the fourth through hole 3121, the outer edge of the second sealing member 50 is arranged between the connecting member 312 and the inner pot cover 20, and the inner edge of the second sealing member 50 is arranged between the mounting seat 31 and the connecting member 312. In this embodiment, the mounting seat 31 can squeeze the second sealing member 50, so that the second sealing member 50 is squeezed on the surface of the inner pot cover 20, so that the sealing effect can be ensured. The setting of the connecting member 312 can abut against the second sealing member 50, so that the second sealing member 50 can undergo a certain elastic deformation, so that the second sealing member 50 has a better sealing effect. In other embodiments not shown in the figures, the mounting seat and the connecting member can also be an integrally formed structure.

[0040] like Figure 3 , Figure 5 and Figure 6 As shown, the second sealing member 50 includes a connecting portion 51 and a sealing ring 52, the connecting portion 51 is sandwiched between the mounting seat 31 and the connecting member 312, the sealing ring 52 is arranged between the connecting member 312 and the inner pot cover 20, the mounting seat 31 includes a first seat body 3111 and a flange 3112 arranged on the side wall of the first seat body 3111, the connecting member 312 includes a second seat body 3122 and a barrel 3123 extending downward from the second seat body 3122, the fourth through hole 3121 is arranged on the second seat body 3122, the flange 3112 is located below the second seat body 3122 and has a gap with the second seat body 3122, the connecting portion 51 is arranged between the flange 3112 and the second seat body 3122, and the sealing ring 52 is arranged between the barrel 3123 and the inner pot cover 20. The end surface of the flange 3112 facing the inner pot cover 20 is an annular surface 311.

[0041] The convex edge 3112 is provided with an annular groove, and the connecting part 51 is provided with an annular convex part extending into the annular groove. The annular convex part cooperates with the annular groove to prevent the connecting part 51 from displacement, thereby preventing the second sealing member 50 from separating from the mounting seat 31 and the connecting member 312.

[0042] like Figure 3 and Figure 6 As shown, the second sealing member 50 further includes a middle portion 53 connected between the connecting portion 51 and the sealing ring 52 , and the middle portion 53 is disposed on the inner side of the cylinder portion 3123 .

[0043] In the present embodiment, a part of the connecting portion 51 is clamped by the mounting seat 31 and the connecting member 312. Compared with the second sealing member 50 being connected to the inner pot cover 20 or the connecting member 312 alone, the clamping arrangement enables the connecting portion 51 to be more firmly connected between the mounting seat 31 and the connecting member 312. Of course, in other embodiments not shown in the figures, the connecting portion can also be connected to the inner pot cover, the mounting seat or the connecting member. In the present embodiment, the sealing ring 52 is arranged between the connecting member 312 and the inner pot cover 20. The sealing ring 52 is annular and extends to the outside of the connecting portion 51 along the inner surface of the inner pot cover 20. When the connecting member 312 applies force to the second sealing member 50, the sealing ring 52 can be elastically deformed and can seal the connecting member 312 and the inner pot cover 20.

[0044] In this embodiment, the connecting portion 51 is provided with a fifth through hole penetrating the first base body 3111, and the connecting portion 51 is sleeved on the first base body 3111 through the fifth through hole. When there is pressure in the pot body, the inner pot cover 20 will be subjected to a certain pressure, the second sealing member 50 is arranged between the second base body 3122 and the inner pot cover 20, the connecting member 312 and the upper cover assembly 10 can be connected in a floating manner, and the second base body 3122 can apply a force to the second sealing member 50. When the force applied by the second base body 3122 to the connecting portion 51 and the pressure applied upward by the inner pot cover 20 act together, the sealing ring 52 will be clamped, further improving the sealing effect. In addition, in order to make the sealing ring 52 seal evenly, the barrel 3123 can apply a more uniform force to the sealing ring 52. The connecting portion 51 is an annular structure, which makes the strength of the connecting portion 51 higher.

[0045] like Figure 2 and Figure 3 As shown, a step portion is provided in the middle of the first seat body 3111, and the step portion is in abutment with the second seat body 3122. The top of the first seat body 3111 passes through the fourth through hole 3121 and is fixed by a fastener 70. The step portion can position the first seat body 3111 relative to the second seat body 3122 along the axial direction, and the first seat body 3111 can be fixed to the second seat body 3122 by cooperation with the fastener 70. The fastener 70 is preferably a nut.

[0046] like Figure 4 As shown, in this embodiment, the upper cover assembly 10 includes an inner lining 12 and a fixing box 80, the first through hole 11 is provided on the inner lining 12, the fixing box 80 is connected at the first through hole 11 and covers the connecting member 312, and the pot cover assembly further includes an elastic member 60 provided between the fixing box 80 and the connecting member 312. The fixing box 80 is fixed to the inner lining 12 by screws. The fixing box 80 can fix the temperature measuring assembly to the inner lining 12. Specifically, the elastic member 60 is provided between the fixing box 80 and the connecting member 312.

[0047] like Figure 4 and Figure 6 As shown, in this embodiment, the second seat body 3122 includes a barrel base portion and a flat plate portion arranged inside the barrel base portion. The portion of the barrel base portion located below the flat plate portion forms a barrel portion 3123, and the above structure is easy to process. The connecting portion 51 is arranged between the convex edge 3112 and the flat plate portion of the second seat body 3122.

[0048] A plurality of guide ribs are arranged at intervals along the circumferential direction on the side wall of the barrel base, and an annular convex edge is arranged at the upper end of the barrel mouth of the barrel base. The fourth through hole 3121 is opened at the center of the flat plate portion. A guide groove cooperating with a plurality of guide ribs is arranged on the hole wall of the first through hole 11. The cooperation between the guide rib and the guide groove enables the connecting member 312 to move up and down along the axial direction of the first through hole 11, and the second seat body 3122 cannot rotate. The above structure prevents the connecting member 312 from rotating when floating up and down. The annular convex edge stops above the first through hole 11 to prevent the connecting member 312 from detaching from the lining 12 when moving downward. Of course, the number of guide ribs and guide grooves can also be one or more than three.

[0049] In this embodiment, the temperature measuring component 30 is arranged on the upper cover component 10, and the temperature measuring column 32 of the temperature measuring component 30 at least partially extends to the lower surface of the inner pot cover 20. The temperature measuring column 32 includes a metal tube composed of a tube wall and a bottom and a temperature sensing element located in the metal tube. The temperature sensing element is close to the tube wall and is located at the bottom of the metal tube. Preferably, the metal tube is a drawing part, and the metal tube is a stainless steel tube, an aluminum alloy tube or a copper tube. The wall thickness of the metal tube is between 0.2mm-1.2mm. The temperature measuring column 32 also includes a heat-conducting medium and a sealing medium. The heat-conducting medium is located between the temperature sensing element and the inner side wall of the metal tube. The sealing medium is encapsulated on the temperature sensing element. The distance between the temperature sensing element and the inner side wall of the metal tube is within 3mm. The above distance can ensure a good temperature measurement effect of the metal tube.

[0050] The mounting base 31 and the temperature measuring column 32 of the temperature measuring component 30 can be connected together by riveting, welding or ultrasonic, or can be integrally formed. In this embodiment, the temperature in the pot is detected by the temperature sensing element, and the temperature is transmitted to the control system through the lead wire, thereby effectively controlling the temperature in the pot.

[0051] The present application also provides a cooking utensil, the cooking utensil of this embodiment comprises a pot body 1 and a pot cover assembly 2 arranged on the pot body 1, the pot cover assembly is the above-mentioned pot cover assembly. The above-mentioned pot cover assembly can solve the problem of poor sealing between the temperature measuring device and the inner pot cover assembly in the related art.

[0052] The cooking utensil pot of this embodiment also includes an inner pot and a heating device arranged in the pot body 1. The heating device is installed inside the pot body 1 and is located between the pot body 1 and the inner pot. It should be noted that the cooking utensil can be an electric pressure cooker, an electric rice cooker, a low-pressure rice cooker, a soybean milk maker, a food processor, an electric stew pot and other products.

[0053] In the description of the present invention, it is necessary to understand that the directions or positional relationships indicated by directional words such as "front, back, up, down, left, right", "lateral, vertical, perpendicular, 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 devices or elements 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 contours of each component itself.

[0054] For ease of description, spatially relative terms such as "above", "above", "on the upper surface of", "above", etc. may be used here to describe the spatial positional relationship between a device or feature and other devices or features as shown in the figure. 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 figure.
