Description

Technical Field

[0001] The present invention relates to the technical field of small household appliances, and in particular to a cover assembly and a cooking utensil having the same. Background Art

[0002] Cooking utensils are indispensable kitchen equipment in daily life. Cooking utensils are used to prepare and cook various foods. The cooking utensils include a pot body and a cover assembly. The cover assembly can be opened and closed on the pot body. The pot body is used to hold food. When the cover assembly is buckled on the pot body, the cover assembly can maintain the heat and steam inside the pot body, thereby promoting uniform cooking of food by the cooking utensils.

[0003] In the related art, the cover assembly includes an outer cover and an inner cover, the inner cover has cover teeth that can be engaged with pot teeth of the pot body, and the inner cover is rotatably arranged on the outer cover around its axis so that the cover teeth can be engaged with or separated from the pot teeth.

[0004] However, when the inner cover of the lid assembly in the related art is rotated to open and close the lid, the inner cover is prone to tilt, and the tilt of the inner cover may cause interference between the lid teeth and the pot teeth, resulting in unsmooth opening and closing of the lid. Summary of the invention

[0005] 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 in the related art that the inner cover of the cover assembly is prone to tilt when the inner cover is rotated to open and close the cover.

[0006] In order to achieve the above-mentioned purpose, according to one aspect of the present invention, a cover body assembly is provided, including: an outer cover, including a first top plate and a first enclosure plate arranged around the edge of the first top plate and extending downward, a slide groove is arranged on the inner side wall of the first enclosure plate; an inner cover, which is detachably and rotatably arranged below the outer cover, the inner cover includes a second top plate and a second enclosure plate arranged around the edge of the second top plate and extending downward, an insert block slidably matched with the slide groove is arranged on the outer side wall of the second enclosure plate, the size of the slide groove along the circumference of the outer cover is larger than the size of the insert block along the circumference of the outer cover, the width of the slide groove is larger than the size of the insert block along the width direction of the slide groove, and a cover tooth that is buckled with the pot tooth of the pot body of the cooking utensil is arranged on the lower edge of the second enclosure plate; an elastic member is arranged between the first top plate and the second top plate, and there is a preset distance between the elastic member and the center line of the inner cover, so that the inner cover can be floatingly installed below the outer cover.

[0007] By applying the technical solution of the present invention, the cover assembly includes an outer cover, an inner cover and an elastic member. When the inner cover is installed on the outer cover, the cover assembly is placed on the pot body. Since the size of the slide groove along the circumference of the outer cover is larger than the size of the insert block along the circumference of the outer cover, the inner cover can be rotated relative to the outer cover, and the insert block slides in the slide groove along the rotation direction, so that the cover teeth and the pot teeth of the pot body are engaged or separated. During the cooking process, since the width of the slide groove is larger than the size of the insert block along the width direction of the slide groove, and the elastic member is arranged between the first top plate and the second top plate, as the pressure in the pot body changes, the inner cover floats relative to the pot body in a direction close to or away from the outer cover, and the insert block slides in the slide groove along the floating direction. Furthermore, since the width of the slide groove is greater than the dimension of the insert block along the width direction of the slide groove, the elastic member is arranged between the first top plate and the second top plate, and there is a preset distance between the elastic member and the center line of the inner cover, so that the inner cover can float relative to the pot body in a direction closer to or away from the outer cover. Therefore, when the cover body assembly is placed on the pot body and the inner cover rotates relative to the outer cover, the pressure applied to the inner cover by the elastic member can overcome the inclination of the inner cover, thereby avoiding interference between the cover teeth and the pot teeth, and allowing the cover body assembly to open and close smoothly.

[0008] Furthermore, the outer cover also includes a face cover that covers the first top plate and the first enclosure, and the elastic member includes an abutment column and a spring. The abutment column is inserted into the first top plate, and the spring is arranged between the face cover and the abutment column, and applies an elastic force toward the inner cover to the abutment column. The face cover can shield the first top plate and the first enclosure, and the spring is used to apply an elastic force toward the inner cover to the abutment column. The abutment column can reliably contact the inner cover, so that the abutment column applies pressure to the inner cover to overcome the possibility of the inner cover tilting. This makes the elastic member low-cost, easy to install, and reliable.

[0009] Furthermore, the cover assembly further comprises a mounting seat for mounting the elastic member, the mounting seat being arranged between the first top plate and the face cover, and the spring being arranged between the mounting seat and the abutment column. By arranging the spring between the mounting seat and the abutment column, it is convenient to install the spring, and the spring can be prevented from falling off during the floating process of the inner cover.

[0010] Furthermore, the abutment column includes a first column section and a second column section connected to the first column section, a guide hole that cooperates with the first column section is provided on the first top plate, the diameter of the second column section is smaller than the diameter of the first column section, a stop surface is formed between the second column section and the first column section, a spring is provided between the face cover and the stop surface, and the first column section can cooperate with the second top plate. By sleeve-arranging the spring on the second column section and providing the spring between the face cover and the stop surface, it is convenient to install the spring, and it is also convenient for the spring to apply an elastic force toward the inner cover to the abutment column. In the process of the inner cover rotating relative to the outer cover, when the first column section is in cooperation with the guide hole for guidance, the first column section applies a pressure perpendicular to the guide direction of the guide hole to the second top plate, so that the inner cover can achieve balanced rotation, effectively reducing the possibility of the inner cover tilting.

[0011] Furthermore, the upper surface of the second top plate is a horizontal surface that abuts against the elastic member. Since the elastic member abuts against the horizontal surface on the second top plate, when the lid assembly is placed on the pot body and the inner lid rotates relative to the outer lid, the elastic member can be used to support the inner lid to prevent the inner lid from tilting.

[0012] Furthermore, a guide structure is provided between the outer cover and the inner cover, the guide structure comprising a guide groove and a guide column that cooperates with the guide groove for guidance, one of the guide groove and the guide column is provided on the outer cover, and the other is provided on the inner cover. When the inner cover rotates inside the outer cover, the guide column rotates along the guide direction of the guide groove, so that the inner cover rotates inside the outer cover more smoothly and with less shaking.

[0013] Furthermore, in the up-down direction of the outer cover, there is a first distance between the bottom of the guide groove and the top of the guide post, and there is a second distance between the top wall of the inner cover and the top wall of the outer cover, and the first distance is greater than or equal to the second distance. When the cooking utensil is pressed upward, the above-mentioned structural arrangement enables the guide post to continue to be inserted into the guide groove in the direction of the bottom of the guide groove, thereby providing sufficient floating space for the inner cover to float upward, thereby meeting the floating requirement of the inner cover.

[0014] Furthermore, a concave portion is provided on the upper surface of the second top plate, and the concave surface of the concave portion is a horizontal surface that abuts against the elastic member. Since the elastic member abuts against the horizontal surface on the second top plate, when the lid assembly is placed on the pot body and the inner lid rotates relative to the outer lid, the elastic member can be used to support the inner lid to prevent the inner lid from tilting.

[0015] Furthermore, an exhaust pipe is provided on the outer cover, and an avoidance hole for the exhaust pipe to pass through is provided on the second top plate. By providing the avoidance hole, the inner cover can be detachable relative to the outer cover with minimal modification to the cover body assembly. In this way, the avoidance hole only avoids the exhaust pipe. Since the pivot in the related art is not provided on the outer cover, the avoidance hole does not need to be provided as a pivot hole that cooperates with the pivot, thereby reducing components and reducing costs. In addition, the exhaust pipe provided on the outer cover will not interfere with the pivot in the related art, and there is no need to adjust the original setting position of the exhaust pipe on the outer cover, thereby ensuring the original layout design on the outer cover, that is, the exhaust pipe can be retained in the original position with minimal modification to the cover body assembly of the present application. In this way, during the mold processing of the outer cover and the inner cover, there is no need to make major adjustments to the mold, thereby reducing design costs and improving processing efficiency.

[0016] Furthermore, a stopper is provided on the lower surface of the first top plate, and a support surface and an avoidance concave surface are provided on the upper surface of the second top plate. When the inner cover is installed on the outer cover and the cover teeth and the pot teeth are separated, the support surface cooperates with the stopper, and when the inner cover is rotated below the outer cover to make the cover teeth and the pot teeth buckle together, the avoidance concave surface cooperates with the stopper. When installing the inner cover, the inner cover needs to be tilted relative to the outer cover. When the inner cover is installed on the outer cover, the support surface cooperates with the stopper to make the inner cover in a horizontal state, and then the inner cover is rotated relative to the outer cover. When the cover teeth and the pot teeth are buckled together, the avoidance concave surface is used to avoid the stopper, so that when the inner cover floats, the stopper can float in the avoidance concave surface.

[0017] Furthermore, a guide groove is provided on the inner side wall of the first enclosure, and a clamping block cooperating with the guide groove is provided on the outer side wall of the second enclosure. When installing the inner cover, the inner cover is tilted relative to the outer cover to insert the insert block into the slide groove, and then the inner cover is pushed, so that the inner cover swings toward the direction close to the outer cover with the insert block as the swing point, so that the clamping block extends into the guide groove, thereby installing the inner cover on the outer cover. When the inner cover is removed, the inner cover is pulled, so that the inner cover is swung in a direction away from the outer cover with the insertion block as the swing point, so that the card block is disengaged from the guide slot, and the inner cover is tilted relative to the outer cover to facilitate the insertion block to be taken out from the slide slot; the cover body assembly also includes a supporting member movably arranged on the outer cover, the supporting member has a avoidance position to avoid the card block from entering the guide slot and a supporting position to support the card block so that the card block is maintained in the guide slot, when the supporting member is in the avoidance position, the inner cover can be removed from the outer cover, and when the supporting member is in the supporting position, the inner cover is installed on the outer cover, and when the inner cover is installed, the inner cover is tilted relative to the outer cover to insert the insertion block into the slide slot, and then the inner cover is pushed, so that the inner cover is swung in a direction close to the outer cover with the insertion block as the swing point, so that the card block presses the supporting member, the supporting member switches to the avoidance position, the card block extends into the guide slot, and the supporting member switches to the supporting position, thereby the inner cover is installed on the outer cover. When removing the inner cover, the supporting member is switched to the avoidance position, and the inner cover is pulled, so that the inner cover is swung away from the outer cover with the insert block as the swing point, so that the card block is disengaged from the guide groove, and the inner cover is tilted relative to the outer cover to facilitate the removal of the insert block from the slide groove.

[0018] According to another aspect of the present invention, a cooking utensil is provided, comprising a cover assembly, wherein the cover assembly is the cover assembly provided above. When the inner cover is mounted on the outer cover, the cover assembly is placed on the pot body, and since the dimension of the slide groove along the circumference of the outer cover is larger than the dimension of the plug block along the circumference of the outer cover, the inner cover can rotate relative to the outer cover, and the plug block slides in the slide groove along the rotation direction, so that the cover teeth and the pot teeth of the pot body are engaged or separated, and during the cooking process, since the width of the slide groove is larger than the dimension of the plug block along the width direction of the slide groove, and the elastic member is arranged between the first top plate and the second top plate, the inner cover floats relative to the pot body in a direction close to or away from the outer cover as the pressure in the cooking cavity changes, and the plug block slides in the slide groove along the floating direction. Furthermore, since the width of the slide groove is greater than the dimension of the insert block along the width direction of the slide groove, the elastic member is disposed between the first top plate and the second top plate, so that the inner cover can float relative to the pot body in a direction close to or away from the outer cover, so that when the cover assembly is disposed on the pot body and the inner cover rotates relative to the outer cover, the elastic expansion and contraction of the elastic member can be utilized to prevent the inner cover from tilting, thereby preventing the cover teeth from interfering with the pot teeth, so that the cover assembly can open and close the cover smoothly. Furthermore, when the inner cover is removed from the outer cover, the elastic member exerts an elastic force on the inner cover in a direction away from the outer cover, so that the inner cover can be away from the outer cover, making it easy for the user to remove the inner cover.

[0043] like Fig.14 and Fig.15 As shown, an embodiment of the present invention provides a cover assembly, which includes an outer cover 10, an inner cover 20 and an elastic member 30. The outer cover 10 includes a first top plate 11 and a first enclosure 12 arranged around the edge of the first top plate 11 and extending downward. A slide groove 121 is arranged on the inner side wall of the first enclosure 12. The inner cover 20 is detachably and rotatably arranged below the outer cover 10. The inner cover 20 includes a second top plate 21 and a second enclosure 22 arranged around the edge of the second top plate 21 and extending downward. The outer side wall of the second enclosure 22 is provided with a slide groove 121. The outer cover 10 is provided with a slidingly matched inserting block 221, the dimension of the slide groove 121 along the circumference of the outer cover 10 is larger than the dimension of the inserting block 221 along the circumference of the outer cover 10, the width of the slide groove 121 is larger than the dimension of the inserting block 221 along the width direction of the slide groove 121, the lower edge of the second enclosing plate 22 is provided with a cover tooth 222 that is buckled with the pot tooth of the pot body of the cooking utensil, the elastic member 30 is provided between the first top plate 11 and the second top plate 21, and there is a preset distance between the elastic member 30 and the center line of the inner cover 20, so that the inner cover 20 can be installed below the outer cover 10 in a floating manner. The provision of one elastic member 30 can effectively reduce the cost.

[0044] The elastic member 30 is arranged between the first top plate 11 and the second top plate 21, and there is a preset distance between the elastic member 30 and the center line of the inner cover 20. The elastic member 30 elastically supports the inner cover 20, so that the inner cover 20 can float relative to the pot body in a direction close to or away from the outer cover 10. Therefore, when the cover assembly is placed on the pot body and the inner cover 20 rotates relative to the outer cover 10, the pressure applied to the inner cover 20 by the elastic member 30 can overcome the inclination of the inner cover 20, thereby avoiding interference between the cover teeth and the pot teeth, so that the cover assembly can open and close smoothly.

[0045] It should be noted that the elastic member of the present application can be one, and the preset distance between the elastic member 30 and the center line of the inner cover 20 means that when an elastic member is set on the outer cover and is located on the side close to the plug block 221, the plug block of the inner cover can rotate along the slide groove to prevent the inner cover 20 from tilting.

[0046] The preset distance between the elastic member 30 and the center line of the inner cover 20 means that when an elastic member is set at a position away from both the plug block and the card block, the three parts formed by the elastic member, the plug block and the card block (see below) enable the inner cover to rotate on a plane and prevent the inner cover 20 from tilting.

[0047] When the first top plate 11 is circular, an elastic member is arranged on the first top plate 11, and a preset distance is provided between the elastic member 30 and the center line of the inner cover 20, which means that in the circumferential direction of the first top plate 11, the elastic member and the slide groove 121 are spaced apart. When the inner cover 20 rotates relative to the outer cover 10 and the plug 221 slides in the slide groove 121 along the rotation direction, since the elastic member and the slide groove 121 are spaced apart, the pressure applied by the elastic member to the inner cover 20 keeps the plug 221 in a state of sliding in the slide groove 121 along the rotation direction, so that the inner cover 20 can rotate smoothly.

[0048] like Fig.14 and Fig.15 As shown, the elastic member is one, and one elastic member is arranged at intervals with the guide structure. A guide structure is arranged between the outer cover 10 and the inner cover 20. The guide structure includes a guide groove 41 and a guide column 42 that cooperates with the guide groove 41. One of the guide groove 41 and the guide column 42 is arranged on the outer cover 10, and the other is arranged on the inner cover 20. During the rotation of the inner cover 20 on the inner side of the outer cover 10, the above-mentioned guide column 42 rotates along the guide direction of the guide groove 41, so that the rotation of the inner cover 20 on the inner side of the outer cover 10 is more stable and the shaking is smaller. And under the elastic support of the inner cover provided by the elastic member, the inner cover 20 rotates more smoothly on the inner side of the outer cover 10, effectively reducing the possibility of tilting. The structure of the guide column 42 and the guide groove 41 is simple and easy to process. The diameter of the guide column 42 is less than or equal to the groove width of the guide groove 41.

[0049] In other embodiments, the guide post 42 is disposed on the outer cover 10 , and the guide groove 41 is disposed on the inner cover 20 .

[0050] like Fig.14 and Fig.15 As shown, when the cooking utensil is pressed upward, in order to avoid interference between the inner cover 20 and the outer cover 10 when floating, in the up-down direction of the outer cover 10, there is a first distance between the bottom of the guide groove 41 and the top of the guide post 42, and there is a second distance between the top wall of the inner cover 20 and the top wall of the outer cover 10, and the first distance is greater than or equal to the second distance. In this way, when the cooking utensil is pressed upward, the guide post 42 can continue to be inserted into the guide groove 41 in the direction of the bottom of the guide groove 41, providing sufficient floating space for the inner cover 20 to float, and meeting the floating requirement of the inner cover 20.

[0051] like Figures 1 to 13 As shown, an embodiment of the present invention provides another cover assembly, which includes an outer cover 10, an inner cover 20 and a plurality of elastic members 30. The outer cover 10 includes a first top plate 11 and a first enclosure 12 arranged around the edge of the first top plate 11 and extending downward, and a slide groove 121 is arranged on the inner side wall of the first enclosure 12. The inner cover 20 is detachably and rotatably arranged below the outer cover 10. The inner cover 20 includes a second top plate 21 and a second enclosure 22 arranged around the edge of the second top plate 21 and extending downward, and a second enclosure 22 is arranged on the outer side wall of the second enclosure 22 to be connected to the slide groove 121. The outer cover 10 is provided with an inserting block 221 which is slidably matched, the dimension of the slide groove 121 along the circumferential direction of the outer cover 10 is larger than the dimension of the inserting block 221 along the circumferential direction of the outer cover 10, the width of the slide groove 121 is larger than the dimension of the inserting block 221 along the width direction of the slide groove 121, the lower edge of the second enclosing plate 22 is provided with a cover tooth 222 which is buckled together with the pot tooth of the pot body of the cooking utensil, a plurality of elastic members 30 are provided between the first top plate 11 and the second top plate 21, and a preset distance is provided between the elastic members 30 and the center line of the inner cover 20, so that the inner cover 20 can be installed below the outer cover 10 in a floating manner.

[0052] The cover assembly provided in this embodiment is applied, and the cover assembly includes an outer cover 10, an inner cover 20 and an elastic member 30. When the inner cover 20 is installed on the outer cover 10, the cover assembly is placed on the pot body. Since the size of the slide groove 121 along the circumference of the outer cover 10 is larger than the size of the insert block 221 along the circumference of the outer cover 10, the inner cover 20 can rotate relative to the outer cover 10, and the insert block 221 slides in the slide groove 121 along the rotation direction, so that the cover teeth 222 are engaged with or separated from the pot teeth of the pot body. During the cooking process, since the width of the slide groove 121 is larger than the size of the insert block 221 along the width direction of the slide groove 121, and the elastic member 30 is arranged between the first top plate 11 and the second top plate 21, as the pressure in the pot body changes, the inner cover 20 floats relative to the pot body in a direction close to or away from the outer cover 10, and the insert block 221 slides in the slide groove 121 along the floating direction. Furthermore, since the width of the slide groove 121 is greater than the dimension of the insert block 221 along the width direction of the slide groove 121, the elastic member 30 is arranged between the first top plate 11 and the second top plate 21, and there is a preset distance between the elastic member 30 and the center line of the inner cover 20, so that the inner cover 20 can float relative to the pot body in a direction closer to or away from the outer cover 10, so that when the cover assembly is covered on the pot body and the inner cover 20 rotates relative to the outer cover 10, the pressure applied to the inner cover 20 by the elastic member 30 can overcome the inclination of the inner cover 20, thereby avoiding interference between the cover teeth and the pot teeth, so that the cover assembly can open and close the cover smoothly.

[0053] When installing the inner cover 20, the inner cover 20 is tilted relative to the outer cover 10 so that the insert block 221 is inserted into the slide groove 121, and then the inner cover 20 is pushed, so that the insert block 221 is used as a swing point, so that the inner cover 20 is swung in a direction close to the outer cover 10, so that the inner cover 20 is installed on the outer cover 10. When removing the inner cover 20, the inner cover 20 is pulled, so that the insert block 221 is used as a swing point, so that the inner cover 20 is swung in a direction away from the outer cover 10. The inner cover 20 is tilted relative to the outer cover 10 to facilitate the removal of the insert block 221 from the slide groove 121. It should be noted that the center line of the inner cover 20 refers to the rotation axis formed when the inner cover 20 rotates relative to the outer cover 10, and the "plurality" in this application refers to at least two.

[0054] In this embodiment, when the inner cover 20 is installed on the outer cover 10, the plurality of elastic members 30 are evenly distributed on the first top plate 11, and the plurality of elastic members 30 are spaced apart from the insert block, so that the pressure applied by the plurality of elastic members 30 to the inner cover 20 can be evenly distributed, preventing the inner cover 20 from tilting too much relative to the outer cover 10, and improving the smoothness of installation. After the inner cover 20 is installed on the outer cover 10, the plurality of elastic members and the insert block together form at least more than three parts, so that the inner cover is kept rotating on a plane relative to the outer cover 10, and the inner cover 20 can be prevented from tilting.

[0055] like Figure 1 , Figure 4 , Figure 5 , Figure 8 , Fig.11 as well as Fig.12 As shown, the outer cover 10 further includes a cover 13 that is covered on the outside of the first top plate 11 and the first enclosure plate 12, and the elastic member 30 includes an abutment column 31 and a spring 32. The abutment column 31 is penetrated on the first top plate 11, and the spring 32 is arranged between the cover 13 and the abutment column 31, and applies an elastic force toward the inner cover 20 to the abutment column 31. The cover 13 can shield the first top plate 11 and the first enclosure plate 12, and the spring 32 can apply an elastic force toward the inner cover 20 to the abutment column 31. The abutment column 31 can reliably contact the inner cover 20, so that the abutment column 31 can apply pressure to the inner cover 20 to overcome the possibility of the inner cover 20 tilting. The elastic member 30 has low cost, is easy to install, and is reliable.

[0056] like Figure 4 and Figure 5 As shown, the cover assembly further includes a mounting seat 40 for mounting the elastic member 30, the mounting seat 40 is disposed between the first top plate 11 and the face cover 13, and the spring 32 is disposed between the mounting seat 40 and the abutment column 31. By arranging the spring 32 between the mounting seat 40 and the abutment column 31, it is convenient to install the spring 32, and the spring 32 can be prevented from falling off during the floating process of the inner cover 20.

[0057] like Figure 6 and Figure 7 As shown, the abutment column 31 includes a first column section 311 and a second column section 312 connected to the first column section 311. The first top plate 11 is provided with a guide hole 113 for guiding and matching with the first column section 311. The diameter of the second column section 312 is smaller than the diameter of the first column section 311. A stop surface 313 is formed between the second column section 312 and the first column section 311. The spring 32 is arranged between the cover 13 and the stop surface 313. The first column section 311 can abut and match with the second top plate 21. By sleeve-arranging the spring 32 on the second column section 312 and arranging the spring 32 between the cover 13 and the stop surface 313, it is convenient to install the spring 32, and it is also convenient for the spring 32 to apply an elastic force toward the inner cover 20 to the abutment column 31. During the rotation of the inner cover 20 relative to the outer cover 10, when the first column segment 311 is in guiding cooperation with the guide hole, the first column segment 311 applies pressure perpendicular to the guiding direction of the guide hole to the second top plate 21, so that the inner cover 20 can achieve balanced rotation, effectively reducing the possibility of the inner cover 20 tilting.

[0058] In this embodiment, the lower end surface of the first column section 311 is a curved surface that abuts against the second top plate 21. In this way, the first column section 311 and the second top plate 21 can be in smooth contact, and when the inner cover 20 rotates relative to the outer cover 10, the first column section 311 can avoid damaging the second top plate 21.

[0059] In other embodiments, the upper surface of the second top plate 21 is a horizontal surface that abuts against the elastic member 30. Since the elastic member 30 abuts against the horizontal surface on the second top plate 21, when the cover assembly is placed on the pot body and the inner cover 20 rotates relative to the outer cover 10, the elastic member 30 can be used to support the inner cover 20 to prevent the inner cover 20 from tilting.

[0060] Furthermore, the second top plate 21 with the above structure has the advantages of being simple in structure and easy to process.

[0061] In this embodiment, if Figure 3 and Fig.10 As shown, the upper surface of the second top plate 21 is provided with a lower concave portion 211, and the lower concave surface of the lower concave portion 211 is a horizontal surface that abuts and cooperates with the elastic member 30. Since the elastic member 30 abuts and cooperates with the horizontal surface on the second top plate 21, when the cover assembly is covered on the pot body and the inner cover 20 rotates relative to the outer cover 10, the elastic member 30 can be used to support the inner cover 20 to prevent the inner cover 20 from tilting.

[0062] Furthermore, by providing the lower recess 211, the structure between the inner cover 20 and the outer cover 10 is made compact, thereby reducing the overall height of the cover assembly.

[0063] In the related art, a pivot is provided at the center of the outer cover, and the inner cover is connected to the pivot by means of a nut, so that the pivot and the inner cover are movably connected.

[0064] like Figures 1 to 5 as well as Figures 7 to 9 As shown, in this embodiment, the outer cover 10 is provided with an exhaust pipe 14, and the second top plate 21 is provided with an escape hole 212 for the exhaust pipe 14 to pass through. The escape hole 212 is preferably a round hole. By providing the escape hole 212, the inner cover 20 can be detached relative to the outer cover 10 with minimal modification to the cover assembly. In this way, the escape hole 212 only escapes the exhaust pipe 14. Since the outer cover 10 is not provided with a pivot in the related art, the escape hole 212 does not need to be provided as a pivot hole that cooperates with the pivot, which reduces components and reduces costs. Furthermore, the exhaust pipe 14 provided on the outer cover 10 will not interfere with the pivot in the related art, and there is no need to adjust the original setting position of the exhaust pipe 14 on the outer cover 10, thereby ensuring the original layout design on the outer cover 10, that is, the exhaust pipe 14 can be retained in the original position with only minimal modification to the cover body assembly of the present application. In this way, during the mold processing of the outer cover 10 and the inner cover 20, there is no need to make major adjustments to the mold, which can reduce design costs and improve processing efficiency.

[0065] In this embodiment, the exhaust pipe 14 is provided with a pressure limiting valve which can be opened and closed.

[0066] Among them, Figures 1 to 7 As shown, the exhaust pipe is arranged concentrically with respect to the inner cover, that is, the exhaust pipe is arranged coaxially with the rotation axis of the inner cover. Figures 8 to 13 As shown, the exhaust pipe is eccentrically arranged relative to the inner cover, that is, the exhaust pipe is arranged parallel to the rotation axis of the inner cover.

[0067] like Figure 1 , Figure 2 , Figure 3 as well as Fig.10 As shown, a stopper 111 is provided on the lower surface of the first top plate 11, and a support surface 213 and an avoidance concave surface 214 are provided on the upper surface of the second top plate 21. When the inner cover 20 is installed on the outer cover 10 and the cover teeth 222 are separated from the pot teeth, the support surface 213 cooperates with the stopper 111 to stop. When the inner cover 20 rotates under the outer cover 10 to make the cover teeth 222 and the pot teeth buckle together, the avoidance concave surface 214 cooperates with the stopper 111 to avoid. When installing the inner cover 20, the inner cover 20 needs to be tilted relative to the outer cover 10. When the inner cover 20 is installed on the outer cover 10, the support surface 213 is first used to cooperate with the stopper 111 to make the inner cover 20 in a horizontal state, and then the inner cover 20 is rotated relative to the outer cover 10. When the cover teeth 222 and the pot teeth are buckled together, the avoidance concave surface 214 is used to avoid the stopper 111, so that when the inner cover 20 floats, the stopper 111 can float in the avoidance concave surface 214.

[0068] When there is only one elastic member, the elastic member and the stopper 111 are spaced apart, and the elastic member and the stopper 111 cooperate with each other to support the inner cover 20 , thereby effectively preventing the inner cover 20 from tilting when rotating relative to the outer cover 10 .

[0069] like Figure 1 , Figure 2 , Figure 3 , Figure 8 , Fig. 9 as well as Fig.10 As shown, a guide groove 122 is further provided on the inner side wall of the first enclosure 12, and a block 223 is provided on the outer side wall of the second enclosure 22 to guide and cooperate with the guide groove 122. When installing the inner cover 20, the inner cover 20 is tilted relative to the outer cover 10 to insert the insert block 221 into the slide groove 121, and then the inner cover 20 is pushed, so that the inner cover 20 is swung in a direction close to the outer cover 10 with the insert block 221 as the swing point, so that the block 223 extends into the guide groove 122, so that the inner cover 20 is installed on the outer cover 10. When removing the inner cover 20, the inner cover 20 is pulled, so that the inner cover 20 is swung in a direction away from the outer cover 10 with the insert block 221 as the swing point, so that the block 223 is disengaged from the guide groove 122, and the inner cover 20 is tilted relative to the outer cover 10 to facilitate the removal of the insert block 221 from the slide groove 121.

[0070] Moreover, in the present embodiment, the dimension of the guide groove 122 along the circumference of the outer cover 10 is greater than the dimension of the block 223 along the circumference of the outer cover 10. When the inner cover 20 rotates relative to the outer cover 10, the block 223 slides in the guide groove 122 along the rotation direction. The width of the guide groove 122 is greater than the dimension of the block 223 along the width direction of the guide groove 122. When the inner cover 20 floats, the block 223 slides in the guide groove 122 along the floating direction.

[0071] like Figure 1 , Figure 2 , Figure 8 as well as Fig. 9 As shown, the cover body assembly also includes a supporting member 50 movably arranged on the outer cover 10, and the supporting member 50 has an avoidance position for avoiding the card block 223 from entering the guide groove 122 and a supporting position for supporting the card block 223 so that the card block 223 remains in the guide groove 122. When the supporting member 50 is in the avoidance position, the inner cover 20 can be removed from the outer cover 10, and when the supporting member 50 is in the supporting position, the inner cover 20 is installed on the outer cover 10. When installing the inner cover 20, the inner cover 20 is tilted relative to the outer cover 10 to insert the insert block 221 into the slide groove 121, and then the inner cover 20 is pushed, so that the insert block 221 is used as a swing point, so that the inner cover 20 swings in a direction close to the outer cover 10, so that the clamping block 223 presses the supporting member 50, the supporting member 50 switches to the avoidance position, the clamping block 223 extends into the guide groove 122, and the supporting member 50 switches to the supporting position, so that the inner cover 20 is installed on the outer cover 10. When removing the inner cover 20, the supporting member 50 is switched to the avoidance position, and the inner cover 20 is pulled, so that the insert block 221 is used as a swing point, so that the inner cover 20 swings in a direction away from the outer cover 10, so that the clamping block 223 is disengaged from the guide groove 122, and the inner cover 20 is tilted relative to the outer cover 10, so that the insert block 221 can be taken out of the slide groove 121.

[0072] In this embodiment, the inner cover has a first side and a second side that are arranged opposite to each other, the insert block 221 is located on the first side of the inner cover, and the clamp block 223 is located on the second side of the inner cover. In this way, the insert block 221 and the clamp block 223 balance and share the gravity of the inner cover, so that the inner cover rotates more smoothly, and the insert block 221 rotates smoothly in the slide groove 121, and the clamp block 223 rotates smoothly in the guide groove 122.

[0073] like Figure 1 , Figure 2 , Figure 8 as well as Fig. 9 As shown, the first enclosure 12 is provided with a notch 123 extending to one end of the first enclosure 12 away from the first top plate 11 , the supporting member 50 is disposed in the notch 123 , and the block 223 can enter and exit the guide groove 122 through the notch 123 .

[0074] like Figure 3 , Figure 7 and Fig.10 As shown, the inner cover 20 is provided with a first anti-mistake mark 24 pointing to the insert block 221. During the process of inserting the insert block 221 into the slide groove 121, the detachable operation of the inner cover 20 can be facilitated by aligning the first anti-mistake mark 24 and the slide groove 121.

[0075] In this embodiment, the cover body assembly also includes a handle, and a transmission member is movably provided on the outer cover 10, and a driving hole is provided on the transmission member. The transmission member has a first position and a second position. The handle is movably provided on the outer cover 10 and can drive the transmission member to move. A driving column passing through the driving hole is provided on the inner cover 20. When the transmission member moves, the inner cover 20 can be driven to rotate through the driving column. When the transmission member is in the first position, the inner cover 20 is in an unlocked state, and when the transmission member is in the second position, the inner cover 20 is in a locked state. When the inner cover 20 is installed on the outer cover 10, the driving column is passed through the driving hole, the block part is switched to the avoidance position, and the handle is operated to switch the transmission member between the first position and the second position. The transmission member drives the driving column to rotate through the driving hole, and drives the inner cover 20 to rotate relative to the outer cover 10. When the transmission member is in the second position, the inner cover 20 is in a locked state, and the inner cover 20 is buckled with the pot body of the cooking utensil. When the transmission member is in the first position, the inner cover 20 is in an unlocked state, and the inner cover 20 is separated from the pot body of the cooking utensil, and the inner cover 20 can be removed relative to the outer cover 10.

[0076] In this embodiment, a block portion is provided on the abutment column 31, and the block portion is located on the side of the first top plate 11 away from the inner cover 20. When the inner cover 20 is installed below the outer cover 10, the inner cover 20 cooperates with the abutment column 31 to make the block portion located at a avoidance position to avoid the transmission member so that the transmission member can move. When the inner cover 20 is removed from the outer cover 10, the abutment column 31 falls relative to the outer cover 10, so that the block portion is located at a limiting position to limit the transmission member at the first position, thereby preventing the user from misoperating the handle and changing the position of the drive hole, so that when the inner cover 20 is installed again, the drive column can be smoothly inserted into the drive hole, and the inner cover can be smoothly installed on the outer cover. When the inner cover 20 is installed below the outer cover 10, the user does not need to perform additional operations. By using the inner cover 20 and the abutment column 31 to cooperate with each other, the block portion can be moved from the limiting position to the avoidance position, thereby simplifying the user's operation. Another embodiment of the present invention provides a cooking utensil, the cooking utensil includes a cover assembly, and the cover assembly is the cover assembly provided above.

[0077] When the cooking utensil provided in this embodiment is used, when the inner cover 20 is installed on the outer cover 10, the cover body assembly is placed on the pot body. Since the size of the slide groove 121 along the circumference of the outer cover 10 is larger than the size of the insert block 221 along the circumference of the outer cover 10, the inner cover 20 can rotate relative to the outer cover 10, and the insert block 221 slides in the slide groove 121 along the rotation direction, so that the cover teeth 222 are engaged with or separated from the pot teeth of the pot body. During the cooking process, since the width of the slide groove 121 is larger than the size of the insert block 221 along the width direction of the slide groove 121, and a plurality of elastic members 30 are arranged between the first top plate 11 and the second top plate 21, as the pressure in the cooking cavity changes, the inner cover 20 floats relative to the pot body in a direction close to or away from the outer cover 10, and the insert block 221 slides in the slide groove 121 along the floating direction. Furthermore, since the width of the chute 121 is greater than the dimension of the insert 221 along the width direction of the chute 121, a plurality of elastic members 30 are arranged between the first top plate 11 and the second top plate 21, so that the inner cover 20 can float relative to the pot body in a direction close to or away from the outer cover 10, so that when the cover assembly is covered on the pot body and the inner cover 20 rotates relative to the outer cover 10, the elastic expansion and contraction of the elastic members 30 can be used to avoid the inner cover 20 from tilting, thereby avoiding interference between the cover teeth and the pot teeth, so that the cover assembly can open and close smoothly. Furthermore, when the inner cover is removed from the outer cover, the elastic member applies an elastic force to the inner cover in a direction away from the outer cover, so that the inner cover can be away from the outer cover, so that the user can easily remove the inner cover. In this embodiment, the pot body includes a heat preservation cover and an inner pot arranged in the heat preservation cover, and the pot teeth are arranged on the heat preservation cover.

[0078] The cooking utensil of the present embodiment is a one-piece flip-cover electric pressure cooker, the pot body also includes an outer shell arranged on the outside of the heat preservation cover, a hinge structure is arranged between the outer shell and the cover assembly, a control circuit board is arranged in the outer shell, and electrical components such as pressure control and temperature measurement are arranged in the outer cover. The one-piece setting of the one-piece flip-cover electric pressure cooker facilitates the wired connection between the electrical components in the outer cover and the control circuit board in the outer shell, thereby ensuring the reliability of the electrical connection.

[0079] Since a hinge structure is provided between the shell and the cover assembly, when the cover assembly is opened from the pot body, the cover assembly stands on the shell as a whole. At this time, when removing the inner cover 20, the user operates the supporting member 50 to move the supporting member 50 from the supporting position to the avoiding position, pulls the inner cover 20, and then uses the insert block 221 as a swing point to swing the inner cover 20 away from the outer cover 10, so that the block 223 is disengaged from the guide groove 122, and the inner cover 20 is tilted relative to the outer cover 10, so as to facilitate the removal of the insert block 221 from the slide groove 121. Conversely, when installing the inner cover 20 on the outer cover 10, the insert block 221 is inserted into the slide groove 121, and the block 223 slides into the guide groove 122.

[0080] Specifically, a button for driving the supporting member 50 to switch between the supporting position and the avoiding position is provided on the outer cover 10. The supporting member 50 includes a supporting hook that is movably arranged in the outer cover 10 in the transverse direction, and the supporting hook is exerted with elastic force by the first return spring to keep the supporting member 50 in the supporting position.

[0081] In this embodiment, the button can drive the support hook to move in the outer cover 10 in the horizontal direction. When the support member 50 is in the supporting position, the inner cover 20 is placed on the support hook. The cover assembly also includes a first return spring, which is arranged between the support hook and the outer cover 10 and applies an elastic force to the support hook toward the inner cover 20. The support member 50 with the above structure can drive the support hook to move in the horizontal direction in the outer cover 10 by controlling the button. The first return spring is arranged between the support hook and the outer cover 10. When the support member 50 is in the supporting position, the inner cover 20 is placed on the support hook. Under the action of the first return spring, an elastic force can be applied to the support hook, thereby ensuring that the inner cover 20 is placed on the support hook. When it is necessary to control the support member 50 to switch from the supporting position to the avoidance position, the button is pressed, so that the button moves to drive the support hook to overcome the elastic force of the first return spring to move, ensuring that the inner cover 20 is detached from the support hook for removal.

[0082] Compared with the detachable inner cover for repairing the cover assembly in the conventional setting, the supporting member 50 of this embodiment is moved to the supporting position relative to the outer cover 10 by pressing a button, and the inner cover 20 can be mounted on the supporting member 50, so that the inner cover 20 is installed on the outer cover 10, and the supporting member 50 and the inner cover 20 are overlapped and matched, so that the inner cover 20 can be prevented from being separated from the outer cover 10, making the installation method convenient. When the inner cover 20 is removed from the outer cover 10, the supporting member 50 is moved from the supporting position to the avoidance position by pressing a button, so that the inner cover 20 is easily removed from the outer cover 10, and one-button quick removal and easy removal are realized, so that the user can clean the removed inner cover 20 and the outer cover 10. With the cover body assembly adopting the above-mentioned structure, the supporting member 50 on the outer cover 10 can not only facilitate the disassembly and assembly of the inner cover 20 and the outer cover 10, but also when the inner cover 20 is placed on the supporting member 50, the supporting member 50 can support the inner cover 20, and the inner cover 20 can rotate relative to the supporting member 50, which guides the rotation of the inner cover 20, thereby improving the structural reliability and practicality of the cover body assembly.

[0083] In other embodiments, the supporting member 50 includes a pull button swingably disposed on the outer cover 10, and the cover assembly further includes a second return spring, and the pull button is swingably disposed on the outer cover 10. When the supporting member 50 is in the supporting position, the inner cover 20 is mounted on the pull button, and the second return spring is disposed between the pull button and the outer cover 10, and applies an elastic force toward the inner cover 20 to the pull button. The supporting member 50 with the above structure is swingably disposed on the outer cover 10 by means of the pull button, and the second return spring is disposed between the pull button and the outer cover 10, and then when the supporting member 50 is in the supporting position, under the action of the second return spring, the inner cover 20 is ensured to be mounted on the pull button, and when the inner cover 20 is disassembled, the pull button is controlled to swing in a direction away from the inner cover 20, so that the pull button overcomes the elastic force of the second return spring, and then the inner cover 20 is ensured to be separated from the pull button, and then the pull button is reset under the elastic force of the second return spring, and the operation method is simple, and one-button quick disassembly and easy disassembly are realized.

[0084] 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.

[0085] 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. For example, if the device in the accompanying 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.

[0086] In addition, it should be noted that the use of terms such as "first" and "second" to limit components is only for the convenience of distinguishing the corresponding components. If not otherwise stated, the above terms have no special meaning and therefore cannot be understood as limiting the scope of protection of the present invention.
