Technical Field

[0001] The utility model relates to the technical field of small household appliances, and particularly relates to a cover body assembly and a cooking appliance having the same. Background Art

[0002] In daily life, cooking utensils are used to cook food. Since cooking utensils have many functions and can achieve pressure cooking, baking cooking, etc., improving the cooking effect of food, cooking utensils have been more and more widely used in household kitchens or the catering industry. Among them, using a cooking utensil to perform pressure cooking on food can make the food softer and more glutinous.

[0003] In the related art, the inner cover of the cover body assembly is rotatably assembled on the outer cover, and the inner cover will swing relative to the outer cover, resulting in a large friction between the inner cover and the outer cover. Moreover, the exhaust pipe is arranged on the inner cover. Since the soup and debris in the inner pot food are easily splashed onto the inner cover, causing the inner cover to be dirty, it is inconvenient to disassemble the inner cover from the outer cover and the inner cover cannot be cleaned. Summary of the Utility Model

[0004] The utility model provides a cover body assembly and a cooking appliance having the same, so as to solve the problem that in the related art, the inner cover swings relative to the outer cover, resulting in a large friction between the inner cover and the outer cover.

The cover body assembly includes: an outer cover having a downwardly extending mounting post; an inner cover rotatably arranged on the outer cover, the inner cover having a cover tooth adapted to cooperate with the pot tooth of the pot body, the inner cover having a through center hole, the mounting post passing through the center hole and being coaxially arranged with the center hole, and there being a first radial gap between the mounting post and the inner cover; a positioning member mounted in the first radial gap in a manner of being radially clamped by the mounting post and the inner cover, so that there is a second radial gap between the outer side wall of the inner cover and the inner side wall of the outer cover.

[0006] Applying the lid assembly provided in this embodiment, the lid assembly is covered on the pot body. The lid assembly includes an outer lid, an inner lid and a positioning member. The inner lid is rotatably arranged on the outer lid. When the inner lid is assembled on the outer lid, the lid teeth of the inner lid 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 is penetrated through the inner lid. When the inner lid is assembled on the outer lid, the mounting post on the outer lid can be penetrated through the central hole, and the mounting post and the central hole are coaxially arranged, which is convenient for assembly. The positioning member is installed at the first radial gap between the mounting post and the inner lid, and the mounting post and the inner lid radially clamp the positioning member. When the inner lid rotates, due to the radial positioning function of the positioning member, the inner lid will not deviate from the rotation center during the rotation process. And, due to the radial positioning of the positioning member, a second radial gap is formed between the outer side wall of the inner lid and the inner side wall of the outer lid. When the inner lid rotates, the inner lid and the outer lid will not contact. Thus, the contact area between the inner lid and the outer lid can be reduced to reduce the friction force when the inner lid rotates.

[0007] Furthermore, the positioning member is made of an elastic material. The positioning member made of an elastic material can form a good radial positioning for the inner lid and is convenient for the positioning member to form a tight fit with the inner lid during pressure cooking.

[0008] Furthermore, the positioning member has a plugging hole penetrated vertically. The mounting post is penetrated through the plugging hole and is in radial positioning cooperation with the plugging hole. With the above structure, the plugging hole can be used to position the positioning member by the mounting post, so that the positioning member is kept at the first radial gap.

[0009] Furthermore, annular ribs are arranged on the inner side wall of the plugging hole. The mounting post is penetrated through the plugging hole and abuts against the annular ribs, so that the annular ribs are in radial positioning cooperation with the mounting post. With the above structure, annular ribs are arranged on the inner side wall of the plugging hole. Then, when the mounting post is penetrated through the plugging hole, the annular ribs can be in radial positioning cooperation with the mounting post, which is convenient for positioning and installing the mounting post.

[0010] Furthermore, the outer side wall of the positioning member has an annular mounting groove. The inner lid includes a mounting plate surrounding the central hole. The mounting plate extends into the annular mounting groove and is in radial positioning cooperation with the annular mounting groove. With the above structure, the annular mounting groove can be used to position the inner lid by the positioning member, so that the inner lid will not deviate from the rotation center during the rotation process.

[0011] Further, the cover assembly further includes a fixing cylinder, the fixing cylinder has an embedding cylinder section embedded in the annular mounting groove, the outer side wall of the embedding cylinder section has an annular fixing groove, the mounting plate extends into the annular fixing groove and abuts against the annular fixing groove, so that the mounting plate and the annular fixing groove are positioned and matched in the radial direction. With the above structure, by providing the fixing cylinder, the fixing cylinder is sleeved on the outside of the positioning member, that is, the embedding cylinder section of the fixing cylinder extends into the annular mounting groove of the positioning member, thereby facilitating assembly. The embedding cylinder section of the fixing cylinder is assembled and fixed with the inner cover through the annular fixing groove, so that the fixing cylinder can be easily snapped onto the inner cover, and the annular mounting groove of the positioning member can be easily matched with the fixing cylinder.

[0012] Further, the cover assembly further includes an exhaust pipe and a temperature measuring member, and the exhaust pipe and the temperature measuring member are both vertically arranged on the mounting post. This can ensure that both the exhaust pipe and the temperature measuring member are installed on the mounting post. In this way, only the inner cover needs to be disassembled from the outer cover, which is convenient for disassembling and cleaning the inner cover. Moreover, there is no need to disassemble the temperature measuring member and the exhaust pipe. Only a central hole for the mounting post to pass through needs to be provided on the inner cover, and there is no need to provide multiple holes for installing the exhaust pipe and the temperature measuring member. In this way, when the inner cover rotates, the friction force of the inner cover rotation can be reduced, which is convenient for the inner cover to rotate, improving the practicability and reliability of the cover assembly.

[0013] Further, the cover assembly further includes a locking member. The mounting post has a first mounting hole, the exhaust pipe is vertically arranged in the first mounting hole, a limiting boss is arranged on the outer side wall of the exhaust pipe, the exhaust pipe is placed on the upper end of the mounting post through the limiting boss, and the locking member is connected to the exhaust pipe and abuts against the lower end of the mounting post. With the above structure, by arranging the exhaust pipe of the cover assembly in the first mounting hole of the mounting post, the exhaust pipe is placed on the upper end of the mounting post through the limiting boss, and the locking member can fix the exhaust pipe on the mounting post, so that the installation and fixation of the exhaust pipe can be ensured, preventing the exhaust pipe from detaching from the mounting post, enabling the exhaust pipe and the temperature measuring member to be arranged on the mounting post, and only the inner cover needs to be disassembled from the outer cover, which is convenient for disassembling and cleaning the inner cover.

[0014] Furthermore, the mounting post has a second mounting hole, and the temperature measuring component is inserted into the second mounting hole; with the above structure, the temperature measuring component of the cover assembly is inserted into the second mounting hole of the mounting post, so that the temperature measuring component can be installed in the mounting post. The cover assembly also includes a fixing plate, which is clamped between the limiting boss and the upper end of the mounting post, and the fixing plate is pressed on the upper end of the temperature measuring component; with the above structure, by setting the fixing plate, the fixing plate is set between the limiting boss of the exhaust pipe and the upper end of the mounting post, and then the fixing plate can limit the upper end of the temperature measuring component under the action of the fixing plate, so that the fixing plate is pressed on the upper end of the temperature measuring component, and then the exhaust pipe is installed and fixed under the action of the limiting boss and the locking member, and the temperature measuring component is limited and fixed by the fixing plate, so as to prevent the temperature measuring component from being separated from the second mounting hole of the mounting post, and ensure the stability of the installation structure. The cover assembly also includes a fixed cup, which is sleeved on the outside of the mounting column, and the lower end of the exhaust pipe and the lower end of the temperature measuring component are both passed through the fixed cup. The locking member presses the fixed cup to the lower end of the mounting column, and the fixed cup supports the temperature measuring component. With the above structure, by sleeved on the outside of the mounting column, the lower end of the exhaust pipe and the lower end of the temperature measuring component can both pass through the fixed cup, and then the locking member is used to fix the lower end of the fixed cup through the lower end of the exhaust pipe, so that the fixed cup can be installed and fixed, and the exhaust pipe is installed and fixed through the limiting boss and the locking member, the upper end of the temperature measuring component is installed and limited by the fixing sheet, and the lower end of the temperature measuring component is supported and limited by the fixed cup, thereby preventing the temperature measuring component from detaching from the lower end of the mounting column, and ensuring that the exhaust pipe and the temperature measuring component are firmly installed.

[0015] Further, the lid assembly further includes a sealing ring, which is clamped between the lower end of the mounting post and the bottom wall of the fixed cup. The sealing ring has a first sealing hole and a second sealing hole. The exhaust pipe passes through the first sealing hole and is in sealing cooperation with the hole wall of the first sealing hole. The temperature measuring member passes through the second sealing hole and is in sealing cooperation with the hole wall of the second sealing hole. With the above structure, by providing a sealing ring between the lower end of the mounting post and the bottom wall of the fixed cup, the first mounting hole and the second mounting hole of the mounting post can be sealed. Moreover, the sealing ring has a first sealing hole and a second sealing hole, enabling the exhaust pipe to pass through the first sealing hole, and the side wall of the first sealing hole contacts the exhaust pipe to play a sealing role. The temperature measuring member can pass through the second sealing hole, and the side wall of the second sealing hole contacts the temperature measuring member to play a sealing role. Wherein, setting the sealing ring between the lower end of the mounting post and the bottom wall of the fixed cup allows the locking member to be locked at the lower end of the exhaust pipe. The locking member can apply a force to the upper end of the fixed cup, and then the bottom wall of the fixed cup applies a force to the sealing ring to achieve a sealing effect, avoiding the problem that directly applying a force to the sealing ring by the upper end of the locking member may cause uneven stress on the sealing ring and result in warping, ensuring the sealing effect of the sealing ring. The fixed cup includes a bottom plate and an annular side plate. The lower end of the annular side plate is connected to the outer edge of the bottom plate, and the upper end of the annular side plate is provided with a flanging, which is placed on the outer lid. With the above fixed cup, the upper end of the annular side plate is placed on the outer lid through the flanging, and the annular side plate is connected to the bottom plate, which can play a role in fixing the mounting post and facilitate installation and fixation. The locking member includes an anti-blocking nut. The lower end of the exhaust pipe is provided with an external thread, and the anti-blocking nut is threadedly connected to the exhaust pipe through the external thread. The upper end of the anti-blocking nut abuts against the lower end of the mounting post. With the locking member of the above structure, the external thread at the lower end of the exhaust pipe is threadedly connected to the anti-blocking nut, which facilitates the installation and fixation of the exhaust pipe when the anti-blocking nut abuts against the mounting post.

[0016] Further, the outer lid includes an outer lid body and a fixing plate provided on the outer lid body, and the mounting post is provided on the fixing plate.

[0050] 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. Based on the embodiments in the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts belong to the scope of protection of the present invention.

[0051] As Figures 1 to 8 shown, the embodiment of the present invention provides a cover assembly that is covered on a pot body. The cover assembly includes an outer cover 10, an inner cover 20, and a positioning member 90. The outer cover 10 has a downwardly extending mounting post 11. The inner cover 20 is rotatably disposed on 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 through center hole 21. The mounting post 11 is inserted into the center hole 21 and is coaxially disposed with the center hole 21. There is a first radial clearance between the mounting post 11 and the inner cover 20. The positioning member 90 is installed in the first radial clearance L1 in a manner of being radially clamped by the mounting post 11 and the inner cover 20, so that there is a second radial clearance L2 between the outer side wall of the inner cover 20 and the inner side wall of the outer cover 10.

[0052] Applying the cover assembly provided in this embodiment, the cover assembly is covered on the pot body. The cover assembly includes an outer cover 10, an inner cover 20, and a positioning member 90. The inner cover 20 is rotatably disposed on the outer cover 10. When the inner cover 20 is assembled on the outer cover 10, the cover teeth of the inner cover 20 can cooperate with the pot teeth of the pot body to achieve the pressure-bearing function of the cover assembly. Among them, a through center hole 21 is provided in the inner cover 20. When the inner cover 20 is assembled on the outer cover 10, the mounting post 11 on the outer cover 10 can be inserted into the center hole 21, and the mounting post 11 and the center hole 21 are coaxially disposed, which is convenient for assembly. The positioning member 90 is installed at the first radial clearance L1 between the mounting post 11 and the inner cover 20, and the mounting post 11 and the inner cover 20 radially clamp the positioning member 90. When the inner cover 20 rotates, due to the radial positioning function of the positioning member 90, the inner cover 20 will not deviate from the rotation center during the rotation process. And, due to the radial positioning of the positioning member 90, there is a second radial clearance L2 between the outer side wall of the inner cover 20 and the inner side wall of the outer cover 10. When the inner cover 20 rotates, the inner cover 20 and the outer cover 10 will not contact. Thereby, the contact area between the inner cover 20 and the outer cover 10 can be reduced to reduce the friction force when the inner cover 20 rotates.

[0053] In this embodiment, the positioning member 90 is made of an elastic material. The positioning member 90 made of an elastic material can form a good radial positioning for the inner lid 20 and facilitate the formation of a tight fit between the positioning member 90 and the inner lid 20 during pressure cooking.

[0054] It should be noted that when there is no pressure in the cooking cavity of the cooking appliance, there is an axial gap between the positioning member 90 and the inner lid 20, enabling the inner lid 20 to rotate smoothly. During pressure cooking, due to the pressure, the positioning member 90 is pressed against the inner lid 20 to form a tight fit.

[0055] As Figure 14 、 Figure 15 and Figure 17 shown, the positioning member 90 has an insertion hole 97 penetrating vertically. The mounting post 11 passes through the insertion hole 97 and is in positioning cooperation with the insertion hole 97 in the radial direction. With the above structure, the mounting post 11 can be used to position the positioning member 90 by means of the insertion hole 97, so that the positioning member 90 is maintained at the first radial gap L1.

[0056] As Figure 14 、 Figure 15 and Figure 17 shown, an annular rib 971 is provided on the inner side wall of the insertion hole 97. The mounting post 11 passes through the insertion hole 97 and abuts against the annular rib 971, so that the annular rib 971 is in positioning cooperation with the mounting post 11 in the radial direction. With the above structure, an annular rib 971 is provided on the inner side wall of the insertion hole 97. Then, when the mounting post 11 passes through the insertion hole 97, the annular rib 971 can be in positioning cooperation with the mounting post 11 in the radial direction, facilitating the positioning and installation of the mounting post 11.

[0057] As Figure 14 、 Figure 15 and Figure 17 shown, the outer side wall of the positioning member 90 has an annular mounting groove 93. The inner lid 20 includes a mounting plate 22 surrounding the central hole 21. The mounting plate 22 extends into the annular mounting groove 93 and is in positioning cooperation with the annular mounting groove 93 in the radial direction. With the above structure, the positioning member 90 can be used to position the inner lid 20 by means of the annular mounting groove 93, so that the inner lid 20 will not deviate from the rotation center during rotation.

[0058] As Figure 14 、 Figure 15 and Figure 17As shown, the cover assembly further includes a fixing cylinder 94. The fixing cylinder 94 has an embedding cylinder section 941 that embeds into the annular mounting groove 93. The outer sidewall of the embedding cylinder section 941 has an annular fixing groove 9411. The mounting plate 22 extends into the annular fixing groove 9411 and abuts against the annular fixing groove 9411, so that the mounting plate 22 and the annular fixing groove 9411 are positioned and matched in the radial direction. With the above structure, by providing the fixing cylinder 94, the fixing cylinder 94 is sleeved outside the positioning member 90, that is, the embedding cylinder section 941 of the fixing cylinder 94 extends into the annular mounting groove 93 of the positioning member 90, thus facilitating assembly. The embedding cylinder section 941 of the fixing cylinder 94 is assembled and fixed with the inner cover 20 through the annular fixing groove 9411, so that the fixing cylinder 94 can be easily snapped onto the inner cover 20, and the annular mounting groove 93 of the positioning member 90 can be easily matched with the fixing cylinder 94.

[0059] As Figures 1 to 8 shown, the cover assembly further includes an exhaust pipe 30 and a temperature measuring member 40. The exhaust pipe 30 and the temperature measuring member 40 are both vertically arranged on the mounting post 11. This can ensure that both the exhaust pipe 30 and the temperature measuring member 40 are installed on the mounting post 11. In this way, only the inner cover 20 needs to be disassembled from the outer cover 10, which is convenient for disassembling and cleaning the inner cover 20. Moreover, there is no need to disassemble the temperature measuring member 40 and the exhaust pipe 30. Only a central hole 21 for the mounting post 11 to pass through needs to be provided on the inner cover 20, and there is no need to provide multiple holes to install the exhaust pipe 30 and the temperature measuring member 40. In this way, when the inner cover 20 rotates, the friction force during the rotation of the inner cover 20 can be reduced, which is convenient for the inner cover 20 to rotate, improving the practicability and reliability of the cover assembly.

[0060] As Figures 1 to 8 shown, the cover assembly further includes a locking member 50. The mounting post 11 has a first mounting hole 111. The exhaust pipe 30 is vertically inserted into the first mounting hole 111. A limiting boss 31 is provided on the outer sidewall of the exhaust pipe 30. The exhaust pipe 30 is placed on the upper end of the mounting post 11 through the limiting boss 31. The locking member 50 is connected to the exhaust pipe 30 and abuts against the lower end of the mounting post 11. With the above structure, by inserting the exhaust pipe 30 of the cover assembly into the first mounting hole 111 of the mounting post 11, the exhaust pipe 30 is placed on the upper end of the mounting post 11 through the limiting boss 31, and the exhaust pipe 30 can be fixed on the mounting post 11 by using the locking member 50. In this way, the installation and fixation of the exhaust pipe 30 can be ensured, preventing the exhaust pipe 30 from detaching from the mounting post 11, so that the exhaust pipe 30 and the temperature measuring member 40 can be arranged on the mounting post 11. In this way, only the inner cover 20 needs to be disassembled from the outer cover 10, which is convenient for disassembling and cleaning the inner cover 20.

[0061] As Figure 17As shown, a limiting boss 31 is provided on the outer side wall of the exhaust pipe 30. The exhaust pipe 30 is placed on the upper end of the mounting post 11 through the limiting boss 31. The locking member 50 is connected to the exhaust pipe 30 and abuts against the lower end of the mounting post 11. With the above structure, by providing the limiting boss 31 on the outer side wall of the exhaust pipe 30, when the exhaust pipe 30 passes through the first mounting hole 111, the limiting boss 31 is placed on the upper end of the mounting post 11. Furthermore, the limiting boss 31 can ensure that the exhaust pipe 30 is placed on the mounting post 11, and the locking member 50 is used to fix the lower end of the exhaust pipe 30. Then, the lower end of the exhaust pipe 30 passing through the first mounting hole 111 is locked by the locking member 50, so that the exhaust pipe 30 can be fixed under the action of the limiting boss 31 and the locking member 50.

[0062] It should be noted that the exhaust pipe 30 is placed on the upper end of the mounting post 11. "Placed" means that the exhaust pipe 30 is directly placed on the upper end of the mounting post 11, or the exhaust pipe 30 is indirectly placed on the upper end of the mounting post 11.

[0063] As Figure 4 、 Figure 9 、 Figure 13 、 Figure 14 and Figure 17 As shown, the mounting post 11 has a second mounting hole 112, and the temperature measuring element 40 is inserted into the second mounting hole 112. With the above structure, the temperature measuring element 40 of the cover assembly is inserted into the second mounting hole 112 of the mounting post 11, which can ensure that the temperature measuring element 40 is installed in the mounting post 11.

[0064] As Figure 1 、 Figure 3 、 Figure 4 、 Figure 5 、 Figure 7 、 Figure 8 、 Figure 12 、 Figure 13 、 Figure 16 and Figure 17 As shown, the cover assembly further includes a fixing piece 60. The fixing piece 60 is clamped between the limiting boss 31 and the upper end of the mounting post 11, and the fixing piece 60 presses on the upper end of the temperature measuring element 40. With the above structure, by providing the fixing piece 60 and setting the fixing piece 60 between the limiting boss 31 of the exhaust pipe 30 and the upper end of the mounting post 11, the upper end of the temperature measuring element 40 can be limited under the action of the fixing piece 60, so that the fixing piece 60 presses on the upper end of the temperature measuring element 40. Furthermore, the exhaust pipe 30 is installed and fixed under the action of the limiting boss 31 and the locking member 50, and the temperature measuring element 40 is limited and fixed by the fixing piece 60, preventing the temperature measuring element 40 from detaching from the second mounting hole 112 of the mounting post 11 and ensuring the stability of the installation structure.

[0065] AsFigure 1 , Figure 3 , Figure 4 , Figure 5 , Figure 7 , Figure 8 , Figure 12 , Figure 13 , Figure 16 and Figure 17 As shown in Figure 16 and Figure 17 , the cover assembly further includes a fixing cup 70. The fixing cup 70 is sleeved outside the mounting post 11. The lower ends of the exhaust pipe 30 and the temperature measuring element 40 both pass through the fixing cup 70. The locking member 50 presses the fixing cup 70 against the lower end of the mounting post 11. The fixing cup 70 supports the temperature measuring element 40. With the above structure, by sleeving the fixing cup 70 outside the mounting post 11, the lower ends of the exhaust pipe 30 and the temperature measuring element 40 can both pass through the fixing cup 70. Then, the locking member 50 is fixed to the lower end of the fixing cup 70 through the lower end of the exhaust pipe 30, so that the fixing cup 70 can be installed and fixed. And the exhaust pipe 30 is installed and fixed through the limiting boss 31 and the locking member 50. The upper end of the temperature measuring element 40 is installed and limited by the fixing piece 60. The lower end of the temperature measuring element 40 is supported and limited by the fixing cup 70, thereby preventing the temperature measuring element 40 from detaching from the lower end of the mounting post 11 and ensuring the firm installation of the exhaust pipe 30 and the temperature measuring element 40.

[0066] As Figure 1 , Figure 3 , Figure 4 , Figure 5 , Figure 7 , Figure 8 , Figure 13 and Figure 17As shown, the cover assembly further includes a sealing ring 80, which is sandwiched between the lower end of the mounting column 11 and the bottom wall of the fixed cup 70, and has a first sealing hole 81 and a second sealing hole 82. The exhaust pipe 30 is passed through the first sealing hole 81 and is sealed with the hole wall of the first sealing hole 81, and the temperature measuring component 40 is passed through the second sealing hole 82 and is sealed with the hole wall of the second sealing hole 82. With the above structure, by arranging the sealing ring 80 between the lower end of the mounting column 11 and the bottom wall of the fixed cup 70, the first mounting hole 111 and the second mounting hole 112 of the mounting column 11 can be sealed, and the sealing ring 80 has a first sealing hole 81 and a second sealing hole 82, so that the exhaust pipe 30 can be passed through the first sealing hole 81, and the side wall of the first sealing hole 81 contacts the exhaust pipe 30 to play a sealing role, and the temperature measuring component 40 can be passed through the second sealing hole 82, and the side wall of the second sealing hole 82 contacts the temperature measuring component 40 to play a sealing role. The sealing ring 80 is arranged between the lower end of the mounting column 11 and the bottom wall of the fixing cup 70, so that the locking member 50 is locked at the lower end of the exhaust pipe 30. The locking member 50 can apply force to the upper end of the fixing cup 70, so that the bottom wall of the fixing cup 70 applies force to the sealing ring 80 to achieve a sealing effect, thereby avoiding the problem that the upper end of the locking member 50 directly applies force to the sealing ring 80, which will cause the sealing ring 80 to be unevenly stressed and cause it to warp, thereby ensuring the sealing effect of the sealing ring 80.

[0067] like Figure 10 As shown, the fixing cup 70 includes a bottom plate 71 and an annular side plate 72, the lower end of the annular side plate 72 is connected to the outer edge of the bottom plate 71, and the upper end of the annular side plate 72 is provided with a flange, which is placed on the outer cover 10. With the fixing cup 70 described above, the upper end of the annular side plate 72 is placed on the outer cover 10 through the flange, and the annular side plate 72 is connected to the bottom plate 71, so that the mounting column 11 can be fixed, which is convenient for installation and fixing.

[0068] like Figure 1 , Figure 5 , Figure 7 as well as Figure 8 As shown, the locking member 50 includes an anti-blocking nut 51, and the lower end of the exhaust pipe 30 is provided with an external thread 32. The anti-blocking nut 51 is threadedly connected to the exhaust pipe 30 through the external thread 32, and the upper end of the anti-blocking nut 51 abuts against the lower end of the mounting column 11. With the locking member 50 of the above structure, the external thread 32 at the lower end of the exhaust pipe 30 is threadedly connected to the anti-blocking nut 51, so that the exhaust pipe 30 can be installed and fixed when the anti-blocking nut 51 abuts against the mounting column 11.

[0069] It should be noted that the anti-blocking nut 51 abuts against the mounting column 11 , which means that the anti-blocking nut 51 abuts against the mounting column 11 directly, or the anti-blocking nut 51 abuts against the mounting column 11 indirectly.

[0070] As Figure 1 , Figure 5 , Figure 7 and Figure 8 shown, the locking member 50 further includes a spring piece 52, and the spring piece 52 is clamped between the upper end of the anti-blocking nut 51 and the lower end of the mounting post 11. With the locking member 50 having the above structure, a spring piece 52 is provided between the anti-blocking nut 51 and the mounting post 11, and when the anti-blocking nut 51 is threadedly connected to the exhaust pipe 30, the spring piece 52 can apply a downward force to the anti-blocking nut 51, so as to avoid loosening of the anti-blocking nut 51 and ensure the locking function of the locking member 50.

[0071] As Figure 1 , Figure 5 , Figure 9 and Figure 13 shown, the outer cover 10 includes an outer cover body 12 and a fixing plate 13 provided on the outer cover body 12, and the mounting post 11 is provided on the fixing plate 13. With the outer cover 10 having the above structure, a fixing plate 13 is provided on the outer cover body 12, and the mounting post 11 is provided on the fixing plate 13, so as to facilitate the installation and fixation of the mounting post 11 and the fixing plate 13, and also facilitate the fixation of the mounting post 11 on the outer cover body 12, ensuring that the exhaust pipe 30 and the temperature measuring member 40 are installed on the outer cover 10 through the fixing plate 13, and further facilitating the disassembly and cleaning between the outer cover 10 and the inner cover 20.

[0072] It should be noted that, as Figure 11 shown, the positioning member 90 includes a first sealing portion 91 and a second sealing portion 92. The first sealing portion 91 is an annular rib, and the second sealing portion 92 is a conical lip. The outer side wall of the mounting post 11 has a cylindrical surface 113 and a conical surface 114. The first sealing portion 91 is fitted with the cylindrical surface 113 of the mounting post 11, so that the annular rib is in sealing cooperation with the cylindrical surface 113. The second sealing portion 92 is fitted with the conical surface 114 of the mounting post 11, so that the conical surface 114 is in sealing cooperation with the conical lip. Moreover, when the lid assembly is used to seal and bear pressure on the pot body, the inner lid will rise, so that the conical lip fits more tightly with the conical surface 114. Furthermore, as the lid assembly bears pressure, the sealing effect of the second sealing portion 92 on the outer side wall of the mounting post 11 can be improved.

[0073] Among them, as the lid assembly bears pressure, the inner lid 20 rises, so that the positioning member 90 provided on the inner lid 20 can also rise. As a result, the conical lip of the positioning member 90 can fit more tightly with the conical surface 114, and the annular rib of the positioning member 90 can further improve the sealing effect while the conical lip plays a sealing role.

[0074] As Figure 15 and Figure 17As shown, the outer wall of the positioning member 90 has an annular mounting groove 93. The inner cover 20 has a plate-like structure, and the plate-like structure is hermetically inserted into the annular mounting groove 93. With the positioning member 90 having the above structure, by providing the annular mounting groove 93 on the outer wall of the positioning member 90 and the inner cover 20 having a plate-like structure, the inner cover 20 is inserted into the annular mounting groove 93, so that the positioning member 90 can be clamped on the hole wall of the central hole 21 of the inner cover 20 through the annular mounting groove 93, facilitating the assembly of the positioning member 90 on the inner cover 20.

[0075] As Figure 15 and Figure 17 shown, the cover assembly further includes a sealing ring 95. The fixing cylinder 94 is sleeved on the outside of the positioning member 90 and is hermetically fitted with the outer wall of the positioning member 90. The sealing ring 95 is clamped between the plate-like structure and the groove wall of the annular fixing groove 9411. With the above structure, by providing the fixing cylinder 94, the fixing cylinder 94 is sleeved on the outside of the positioning member 90 and is hermetically fitted with the outer wall of the positioning member 90, thus playing a sealing role. The embedding cylinder section 941 of the fixing cylinder 94 is ensured to be assembled and fixed with the inner cover 20 through the annular fixing groove 9411, so that the fixing cylinder 94 can be easily clamped on the inner cover 20, and the annular mounting groove 93 of the positioning member 90 cooperates with the fixing cylinder 94. Moreover, in order to ensure the sealing effect between the fixing cylinder 94 and the inner cover 20, a sealing ring 95 is provided between the inner cover 20 and the groove wall of the annular fixing groove 9411, so that the sealing ring 95 can seal the gap between the fixing cylinder 94 and the inner cover 20, playing a sealing effect.

[0076] As Figure 15 and Figure 17 shown, the cover assembly further includes a clogging prevention cover 96. The clogging prevention cover 96 is sleeved on the outside of the fixing cylinder 94 and is clamped and connected with the fixing cylinder 94. With the above structure, by clamping and connecting the clogging prevention cover 96 with the fixing cylinder 94, the assembly and fixation of the clogging prevention cover 96 can be facilitated.

[0077] As Figures 1 to 4 shown, the outer cover 12 includes a face cover 121 and a lining 122 located below the face cover 121. The fixing plate 13 is arranged on the lining 122. With the above structure, by arranging the fixing plate 13 on the lining 122, the fixation of the fixing plate 13 can be facilitated.

[0078] In this embodiment, the fixing plate 13 is connected to the lining 122 through fasteners. With the above structure, the fixing plate 13 can be fixed on the lining 122 by using fasteners, facilitating assembly.

[0079] In this embodiment, the temperature measuring member 40 is an NTC. The NTC is used to detect the temperature of the pot body, improving the detection effect.
