[0048] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. The following description of at least one exemplary embodiment is actually only illustrative and in no way limits the present invention and its application or use. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present invention without creative efforts shall fall within the protection scope of the present invention.

[0049] As Figures 1 to 10 shown, the embodiment of the present invention provides a cover assembly, which is covered on the pot body. The cover assembly includes an outer cover 10 and an inner cover 20. The outer cover 10 has an installation column 11 extending downward. The inner cover 20 is rotatably arranged below the outer cover 10. The inner cover 20 has cover teeth that cooperate with the pot teeth of the pot body. The inner cover 20 has a central hole 21 penetrating through it. The installation column 11 is inserted into the central hole 21 and is coaxially arranged with the central hole 21. Among them, the cover assembly further includes an exhaust pipe 30, a temperature measuring member 40, and a first sealing ring 50. The exhaust pipe 30 and the temperature measuring member 40 are both arranged vertically on the installation column 11. The first sealing ring 50 is inserted into the central hole 21, and the installation column 11 is inserted into the first sealing ring 50. The outer side wall of the first sealing ring 50 is sealingly matched with the inner cover 20, and the inner side wall of the first sealing ring 50 is sealingly matched with the installation column 11.

[0050] Applying the lid assembly provided by this embodiment, the lid assembly is covered on the pot body. The lid assembly includes an outer lid 10 and an inner lid 20. The inner lid 20 is rotatably arranged below the outer lid 10. When the inner lid 20 is assembled below the outer lid 10, the lid teeth of the inner lid 20 can cooperate with the pot teeth of the pot body to realize the pressure-bearing function of the lid assembly. Among them, a central hole 21 is penetrated through the inner lid 20. When the inner lid 20 is assembled on the outer lid 10, the mounting post 11 on the outer lid 10 can pass through the central hole 21, and the mounting post 11 and the central hole 21 are coaxially arranged, which is convenient for assembly. Specifically, the exhaust pipe 30 and the temperature measuring element 40 in the lid assembly are both vertically arranged on the mounting post 11. The first sealing ring 50 is penetrated through the central hole 21, so that the mounting post 11 is in sealing cooperation with the inner side wall of the first sealing ring 50, and the outer side wall of the first sealing ring 50 is in sealing cooperation with the hole wall of the central hole 21 of the inner lid 20. In this way, it can be ensured that the gap between the mounting post 11 and the hole wall of the central hole 21 of the inner lid 20 is sealed by the first sealing ring 50, and when the lid teeth in the inner lid 20 are used to cooperate with the pot teeth of the pot body, the inner lid 20 of the lid assembly can play a sealing role while bearing pressure during cooking of the pot body, improving the practicability and reliability of the lid assembly.

[0051] As Figure 9 , Figure 10 , Figure 13 , Figure 14 and Figure 17 shown, a first sealing portion 51 is provided on the inner side wall of the first sealing ring 50. The first sealing portion 51 is an annular structure extending along the circumferential direction of the first sealing ring 50, and the first sealing portion 51 is in sealing cooperation with the outer side wall of the mounting post 11. With the above structure, by providing the first sealing portion 51 on the inner side wall of the first sealing ring 50 and using the first sealing portion 51 as an annular structure, the outer side wall of the mounting post 11 can be sealed by the first sealing portion 51, improving the sealing effect of the first sealing ring 50.

[0052] As Figure 14 , Figure 16 and Figure 17 shown, the first sealing portion 51 is an annular rib, and the outer side wall of the mounting post 11 has a cylindrical surface 113. The annular rib is in sealing cooperation with the cylindrical surface 113. With the above structure, by setting the first sealing portion 51 as an annular rib, the first sealing portion 51 is attached to the cylindrical surface 113 of the mounting post 11, so that the first sealing portion 51 can surround the cylindrical surface 113 of the mounting post 11, and the annular rib is in sealing cooperation with the cylindrical surface 113.

[0053] As Figure 9 , Figure 10 , Figure 13 , Figure 14 and Figure 17As shown, a second sealing portion 52 is further provided on the inner sidewall of the first sealing ring 50. The second sealing portion 52 is located below the first sealing portion 51. The second sealing portion 52 is an annular structure extending along the circumferential direction of the first sealing ring 50, and the second sealing portion 52 is in sealing cooperation with the outer sidewall of the mounting post 11. With the above structure, by providing the second sealing portion 52 on the inner sidewall of the first sealing ring 50, and the second sealing portion 52 being located below the first sealing portion 51, when the second sealing portion 52 can abut against the outer sidewall of the mounting post 11, the sealing effect can be ensured. Furthermore, when the inner lid 20 bears pressure, by using the first sealing portion 51 and the second sealing portion 52 to simultaneously abut against and cooperate with the mounting post 11, the sealing effect of the first sealing ring 50 can be improved.

[0054] As Figure 14 、 Figure 16 and Figure 17 shown, the second sealing portion 52 is a conical lip. The outer sidewall of the mounting post 11 has a conical surface 114. The inner hole diameter of the conical lip gradually decreases in the upward to downward direction, and the cross-sectional dimension of the conical surface 114 gradually decreases in the upward to downward direction. The conical lip is in sealing cooperation with the conical surface 114. With the above structure, by setting the second sealing portion 52 as a conical lip and the conical lip fitting with the conical surface 114 of the mounting post 11, the second sealing portion 52 can surround the conical surface 114 of the mounting post 11, enabling the conical surface 114 to be in sealing cooperation with the conical lip. Moreover, when using the cover assembly to seal and bear pressure on the pot body, the inner lid will rise, making the conical lip of the first sealing ring 50 fit more tightly with the conical surface 114. Then, as the cover assembly bears pressure, the sealing effect of the second sealing portion 52 on the outer sidewall of the mounting post 11 can be improved.

[0055] It should be noted that as the cover assembly bears pressure, the inner lid 20 rises, causing the first sealing ring 50 provided on the inner lid 20 to also rise. As a result, the conical lip of the first sealing ring 50 can fit more tightly with the conical surface 114, and the annular rib of the first sealing ring 50 can further improve the sealing effect of the first sealing ring 50 while the conical lip plays a sealing role.

[0056] As Figures 1 to 10 shown, the mounting post 11 has a first mounting hole 111 and a second mounting hole 112. The exhaust pipe 30 is vertically disposed in the first mounting hole 111, and the temperature measuring element 40 is disposed in the second mounting hole 112.

[0057] As Figure 14and Figure 17 As shown in Figure 17 , the outer sidewall of the first sealing ring 50 has an annular mounting groove 53. The inner cover 20 includes a mounting plate 22 which encloses a central hole 21, and a part of the mounting plate 22 is located inside the annular mounting groove 53. For the first sealing ring 50 with the above structure, by providing an annular mounting groove 53 on the outer sidewall of the first sealing ring 50 and the inner cover 20 including the mounting plate 22, the mounting plate 22 is inserted into the annular mounting groove 53, so that the first sealing ring 50 can be clamped on the hole wall of the central hole 21 enclosed by the mounting plate 22 through the annular mounting groove 53, which is convenient for assembling the first sealing ring 50 on the inner cover 20.

[0058] As Figure 1 , Figure 5 , Figure 7 , Figure 8 , Figure 10 and Figure 14 As shown in Figure 14 , the cover assembly further includes a fixing cylinder 60, a second sealing ring 70 and an anti-blocking cover 80. The fixing cylinder 60 is sleeved on the outer side of the first sealing ring 50 and abuts against the outer sidewall of the first sealing ring 50. The second sealing ring 70 is clamped between the mounting plate 22 and the fixing cylinder 60 to seal the radial gap between the mounting plate 22 and the fixing cylinder 60 and mount the fixing cylinder 60 on the mounting plate 22. The anti-blocking cover 80 is sleeved on the outer side of the fixing cylinder 60 and is snap-connected to the fixing cylinder 60. With the above structure, by providing the fixing cylinder 60, the fixing cylinder 60 is sleeved on the outer side of the first sealing ring 50 and is in sealing cooperation with the outer sidewall of the first sealing ring 50, thus playing a sealing role. Moreover, in order to ensure the sealing effect between the fixing cylinder 60 and the inner cover 20, a second sealing ring 70 is provided between the mounting plate 22 and the fixing cylinder 60, so that the second sealing ring 70 can seal the radial gap between the mounting plate 22 and the fixing cylinder 60, playing a sealing effect, and the anti-blocking cover 80 is sleeved on the outer side of the fixing cylinder 60 and is snap-connected to the fixing cylinder 60, which is convenient for mounting the anti-blocking cover 80 on the fixing cylinder 60.

[0059] As Figures 1 to 5 As shown in Figures 1 to 5 , the fixing cylinder 60 has an embedded cylinder section 61 embedded in the annular mounting groove 53. The outer sidewall of the embedded cylinder section 61 has an annular fixing groove 611, the mounting plate 22 is inserted into the annular fixing groove 611, and the second sealing ring 70 is located in the annular fixing groove 611 and is clamped between the mounting plate 22 and the groove wall of the annular fixing groove 611. With the above structure, the embedded cylinder section 61 of the fixing cylinder 60 ensures the assembly and fixation of the fixing cylinder 60 and the inner cover 20 through the annular fixing groove 611, which is convenient for clamping the fixing cylinder 60 on the inner cover 20. The annular mounting groove 53 of the first sealing ring 50 is in sealing cooperation with the fixing cylinder 60, and the second sealing ring 70 is provided in the annular fixing groove 611, so as to seal the gap between the mounting plate 22 and the groove wall of the annular fixing groove 611.

[0060] As Figure 1 , Figure 5 , Figure 7 and Figure 8 shown, the cover assembly further includes a fixing cup 91 and a locking member 92. The fixing cup 91 is sleeved outside the mounting post 11. The lower ends of the exhaust pipe 30 and the temperature measuring member 40 both pass through the fixing cup 91. The locking member 92 presses the fixing cup 91 against the lower end of the mounting post 11. The fixing cup 91 supports the temperature measuring member 40. The inner side wall of the first sealing ring 50 abuts against the outer side wall of the fixing cup 91. With the above structure, the fixing cup 91 is sleeved outside the mounting post 11, and the ends of the exhaust pipe 30 and the lower end of the temperature measuring member 40 can pass through the fixing cup 91. Then, the locking member 92 is fixed to the lower end of the fixing cup 91 through the lower end of the exhaust pipe 30, so that the fixing cup 91 can be installed and fixed. Moreover, the lower end of the temperature measuring member 40 is supported and limited by the fixing cup 91, thereby preventing the temperature measuring member 40 from detaching from the lower end of the mounting post 11. Then, the inner side wall of the first sealing ring 50 is in sealing cooperation with the outer side wall of the fixing cup 91 to ensure the sealing effect between the fixing cup 91 and the inner cover 20.

[0061] As Figure 1 , Figure 5 , Figure 7 and Figure 8 shown, the cover assembly further includes a third sealing ring 93. The third sealing ring 93 is clamped between the lower end of the mounting post 11 and the bottom wall of the fixing cup 91. The third sealing ring 93 has a first sealing hole 931 and a second sealing hole 932. The exhaust pipe 30 passes through the first sealing hole 931 and abuts against the hole wall of the first sealing hole 931. The temperature measuring member 40 passes through the second sealing hole 932 and abuts against the hole wall of the second sealing hole 932. With the above structure, by providing the third sealing ring 93 between the lower end of the mounting post 11 and the bottom wall of the fixing cup 91, the first mounting hole 111 and the second mounting hole 112 of the mounting post 11 can be sealed. Moreover, the third sealing ring 93 has the first sealing hole 931 and the second sealing hole 932, so that the exhaust pipe 30 can pass through the first sealing hole 931, and the side wall of the first sealing hole 931 contacts the exhaust pipe 30 to play a sealing role. The temperature measuring member 40 can pass through the second sealing hole 932, and the side wall of the second sealing hole 932 contacts the temperature measuring member 40 to play a sealing role. Among them, by setting the third sealing ring 93 between the lower end of the mounting post 11 and the bottom wall of the fixing cup 91, the locking member 92 is locked to the lower end of the exhaust pipe 30, and the locking member 92 can apply a force to the upper end of the fixing cup 91. Then, the bottom wall of the fixing cup 91 applies a force to the third sealing ring 93 to achieve a sealing effect, preventing the problem that the upper end of the locking member 92 directly applying a force to the third sealing ring 93 may cause the third sealing ring 93 to be unevenly stressed and warp, and ensuring the sealing effect of the third sealing ring 93.
