[0003] The utility model aims to solve at least one of the technical problems existing in the prior art or related technology.

[0004] To this end, a first aspect of the present invention provides a cover assembly.

[0005] A second aspect of the present invention provides a cooking utensil.

[0006] In view of this, the first aspect of the utility model provides a cover assembly, which is used for a cooking utensil, the cooking utensil includes a pot body, the cover assembly can be covered on the pot body, and the cover assembly includes a cover body, a locking component, a transmission assembly, a drive assembly and a sleeve. The cover body includes a first body and a first mounting column, the first mounting column is connected to the first body; the locking component is connected to the cover body and can rotate relative to the cover body; the transmission assembly is connected to the locking component, the transmission assembly includes a first rack, and the first rack is provided with a first slide groove; the drive assembly is connected to the transmission assembly to drive the locking component to lock or unlock relative to the pot body through the transmission assembly; the sleeve is sleeved on the first mounting column and is located in the first slide groove.

[0007] The cover assembly provided in the present application is used for a cooking utensil, and the cooking utensil includes a pot body, and the cover assembly can be covered on the pot body, and the cover assembly includes a cover body, a locking component, a transmission component, a driving component, and a sleeve. The cover body includes a first body and a first mounting column, and the first mounting column is connected to the first body; the locking component is connected to the cover body and can rotate relative to the cover body; the transmission component is connected to the locking component, and the transmission component includes a first rack, and the first rack is provided with a first slide groove; the driving component is connected to the transmission component, so as to drive the locking component to lock or unlock relative to the pot body through the transmission component, and the driving efficiency of the locking component can be improved under the cooperation of the driving component and the transmission component. The sleeve is sleeved on the first mounting column and is located in the first sliding groove. When the driving assembly drives the locking component through the transmission assembly, the first rack moves relative to the first mounting column through the first sliding groove. Since the first mounting column is sleeved with the sleeve, the first rack contacts the sleeve during the sliding process of the transmission assembly. At the same time, since the sleeve is sleeved on the first mounting column, the sleeve can rotate on the first mounting column. Therefore, the setting of the sleeve enables the first rack to slide and rub against the first mounting column through the sleeve, thereby reducing the friction resistance encountered by the first rack during the sliding process, thereby improving the flexibility of the transmission assembly. At the same time, since the friction resistance of the transmission assembly during the transmission process is reduced, the service life of the transmission assembly can also be extended.

[0008] Specifically, the surface of the shaft sleeve may be polished to further reduce the friction resistance between the shaft sleeve and the transmission assembly.

Therefore, the protection scope of the present invention is not limited to the specific embodiments disclosed below.

[0066] Refer to the following Figures 1 to 13 A lid assembly and a cooking appliance according to some embodiments of the present invention are described.

[0067] In view of this, if Figure 1 and Figure 2 As shown, the first aspect of the utility model provides a cover assembly 100, which is used for a cooking utensil 200. The cooking utensil 200 includes a pot body 220. The cover assembly 100 can be covered on the pot body 220. The cover assembly 100 includes a cover body 110, a locking component 120, a transmission assembly 130, a drive assembly 140 and a sleeve 150. The cover body 110 includes a first body 112 and a first mounting column 114, and the first mounting column 114 is connected to the first body 112; the locking component 120 is connected to the cover body 110 and can rotate relative to the cover body 110; the transmission assembly 130 is connected to the locking component 120, and the transmission assembly 130 includes a first rack 132, and the first rack 132 is provided with a first slide groove 134; the driving assembly 140 is connected to the transmission assembly 130 to drive the locking component 120 to lock or unlock relative to the pot body 220 through the transmission assembly 130; the shaft sleeve 150 is sleeved on the first mounting column 114 and is located in the first slide groove 134.

[0068] The cover assembly 100 provided in the present application is used for a cooking utensil 200, and the cooking utensil 200 includes a pot body 220. The cover assembly 100 can be covered on the pot body 220. The cover assembly 100 includes a cover body 110, a locking component 120, a transmission assembly 130, a drive assembly 140 and a sleeve 150. The cover body 110 includes a first body 112 and a first mounting column 114, and the first mounting column 114 is connected to the first body 112; the locking component 120 is connected to the cover body 110 and can rotate relative to the cover body 110; the transmission assembly 130 is connected to the locking component 120, and the transmission assembly 130 includes a first rack 132, and the first rack 132 is provided with a first slide groove 134; the driving assembly 140 is connected to the transmission assembly 130 to drive the locking component 120 to lock or unlock relative to the pot body 220 through the transmission assembly 130. With the cooperation of the driving assembly 140 and the transmission assembly 130, the driving efficiency of the locking component 120 can be improved. The shaft sleeve 150 is sleeved on the first mounting column 114 and is located in the first sliding groove 134. When the driving assembly 140 drives the locking component 120 through the transmission assembly 130, the first rack 132 moves relative to the first mounting column 114 through the first sliding groove 134. Since the shaft sleeve 150 is sleeved on the first mounting column 114, the first sliding groove 134 contacts the shaft sleeve 150 during the sliding process, and then the first rack 132 slides and rubs against the first mounting column 114 through the shaft sleeve 150. Since the first mounting column 114 is fixed on the cover body 110, the setting of the shaft sleeve 150 can reduce the friction resistance encountered by the first rack 132 during the sliding process, can improve the friction resistance encountered by the transmission assembly 130, improve the flexibility of the transmission assembly 130, and at the same time, due to the reduction of the friction resistance of the transmission assembly 130 during the transmission process, the service life of the transmission assembly 130 can also be extended.

[0069] Specifically, the surface of the sleeve 150 may be polished to further reduce the friction resistance between the sleeve 150 and the transmission assembly 130 .

[0070] Specifically, according to the actual application scenario of the cooking utensil 200 and the cover assembly 100, at least two slide grooves can be set on the transmission assembly 130, and at the same time, a number of first mounting columns 114 equal to the number of the slide grooves can be set on the cover body 110, and at least two first mounting columns 114 are set in the corresponding slide grooves, and at least the first mounting columns 114 play a guiding role for the transmission assembly 130.

[0071] Specifically, the bushings 150 may be disposed on at least two first mounting columns 114 .

[0075] In this embodiment, the sleeve 150 includes a second body 152, and the second body 152 is provided with a through hole 156, and the first mounting column 114 is penetrated in the through hole 156. The through hole 156 is provided to facilitate the installation of the sleeve 150 on the first mounting column 114. By providing the first mounting column 114 with the through hole 156, the first rack 132 can be rubbed against the first mounting column 114 through the sleeve 150 by the cooperation between the first mounting column 114 and the through hole 156, thereby reducing the friction resistance of the first rack 132 during the sliding process, improving the flexibility of the transmission assembly 130, and at the same time, due to reducing the friction resistance of the transmission assembly 130 during the transmission process, the service life of the transmission assembly 130 can also be extended.

[0076] like Figure 3 As shown, the sleeve 150 also includes a first positioning portion 154, which is connected to the second body 152, located on the side of the second body 152 away from the first body 112, and protrudes from the side wall of the second body 152. The first positioning portion 154 is crimped to the side of the first rack 132 away from the first body 112.

The first positioning portion 154 is pressed against a side of the first rack 132 away from the first body 112. The through hole 156 is provided to facilitate mounting the sleeve 150 on the first mounting column 114. Since the first positioning portion 154 is pressed against a side of the first rack 132 away from the first body 112, when the transmission assembly 130 is working, the first rack 132 slides relative to the first mounting column 114, and the first positioning portion 154 can limit the first rack 132 from moving toward the side away from the first body 112, thereby achieving a positioning effect on the first rack 132.

The first positioning portion 154 extending in an annular shape in the circumferential direction can increase the limiting range of the first rack 132 when it slides.

[0081] Specifically, Figure 1 As shown, the circumferential direction of the second body 152 is direction G2.

By setting multiple first positioning portions 154 and arranging the first positioning portions 154 at circumferential intervals, the limiting range of the first positioning portions 154 on the first rack 132 can be increased, and at the same time, the contact surface between the surface of the first positioning portion 154 and the first rack 132 can be reduced, thereby reducing the friction resistance encountered during the sliding process of the first rack 132.

[0085] Specifically, the surface of the first positioning portion 154 may be polished to further reduce the friction resistance encountered by the first rack 132 during sliding, thereby reducing the friction resistance encountered by the transmission assembly 130 .

[0095] This embodiment provides a cover assembly 100. In addition to the technical features of the above embodiments, this embodiment further includes the following technical features.

[0096] like Figure 3 As shown, the cover body 110 also includes a first rib plate 116, which is connected to the first body 112, and the first rib plate 116 and the first body 112 surround a second slide groove 118; the transmission assembly 130 also includes a plurality of positioning ribs 136, and the plurality of positioning ribs 136 are connected to the first rack 132, and are located on the side of the first rack 132 close to the first body 112, and are in contact with the first rib plate 116.

[0097] In this embodiment, the cover body 110 also includes a first rib plate 116, which is connected to the first body 112, and the first rib plate 116 and the first body 112 surround a second slide groove 118; the transmission assembly 130 also includes a plurality of positioning ribs 136, which are connected to the first rack 132, are located on the side of the first rack 132 close to the first body 112, and are in contact with the first rib plate 116. When the driving assembly 140 drives the transmission assembly 130, the transmission assembly 130 slides, the first body 112 is fixed on the cover body 110, and the first rib plate 116 is connected to the first body 112. Since the positioning rib 136 is in contact with the first rib plate 116, the first rib plate 116 and the positioning rib 136 are in contact, so that support can be provided on both sides of the sliding track of the transmission assembly 130, and the transmission assembly 130 can be guided, which facilitates the transmission assembly 130 to drive the locking component 120.

[0098] Specifically, the first rib 116 may be arranged along the edge of the locking component 120 to improve the transmission efficiency of the transmission assembly 130 .

[0099] This embodiment provides a cover assembly 100. In addition to the technical features of the above embodiments, this embodiment further includes the following technical features.

[0100] like Figure 5 and Figure 6 As shown, the transmission assembly 130 further includes a guide post 138 , which is connected to the first rack 132 , located on a side of the first rack 132 close to the first body 112 , and located in the second slide slot 118 .

[0101] In this embodiment, the transmission assembly 130 also includes a guide column 138, which is connected to the first rack 132, is located on the side of the first rack 132 close to the first body 112, and is located in the second slide groove 118. The guide column 138 arranged in the second slide groove 118 is used to limit the movement trajectory of the first rack 132 to achieve the guidance of the transmission assembly 130.

[0102] Specifically, the guide column 138 is arranged on a side of the first rack 132 close to the first body 112, and the guide column 138 is arranged in the second slide groove 118. When the first rack 132 slides relative to the first mounting column 114 under the drive of the driving assembly 140, the inner wall surface in the second slide groove 118 will limit the sliding direction of the guide column 138, guide the first rack 132 connected to the guide column 138, play a role in limiting the first rack 132, and at the same time improve the sliding stability of the first rack 132.

[0103] This embodiment provides a cover assembly 100. In addition to the technical features of the above embodiments, this embodiment further includes the following technical features.

[0104] like Figure 7 As shown, the rotational axis of the drive assembly 140 , the rotational axis of the first rack 132 , and the axis of the first mounting post 114 are coplanar.

[0105] In this embodiment, the rotation axis of the drive assembly 140, the rotation axis of the first rack 132 and the axis of the first mounting column 114 are coplanar. When the drive assembly 140 is working, the three axes are coplanar. The driving force of the first gear 144 on the first rack 132 can be better transmitted to the sleeve 150 through the coplanar design, which can facilitate the positioning of the first rack 132 by the sleeve 150 and improve the positioning effect of the sleeve 150 on the transmission assembly 130.

[0106] Specifically, Figure 4 As shown, after the sleeve 150 is assembled, the sleeve 150 positions the first rack 132, and at the same time, the driving assembly 140 supports the first rack 132 in a colinear manner, thereby improving the uniformity of the force applied to the first rack 132 and avoiding deflection of the first rack 132 during sliding, thereby improving the stability of the sliding process of the first rack 132 and reducing the friction resistance during the sliding process.

[0107] This embodiment provides a cover assembly 100. In addition to the technical features of the above embodiments, this embodiment further includes the following technical features.

[0108] There is a gap between the sleeve 150 and the first mounting column 114 ; and / or there is a gap between the sleeve 150 and the first rack 132 .

[0109] In this embodiment, there is a gap between the sleeve 150 and the first mounting column 114; and / or there is a gap between the sleeve 150 and the first rack 132. By setting a gap between the sleeve 150 and the first mounting column 114, the contact area between the sleeve 150 and the first mounting column 114 can be further reduced when the transmission assembly 130 slides, thereby reducing the magnitude of the frictional resistance encountered by the transmission assembly 130 when sliding. At the same time, a gap can be set between the sleeve 150 and the first rack 132, which can reduce the contact area between the first rack 132 and the sleeve 150, and further reduce the frictional resistance encountered by the first rack 132 when the transmission assembly 130 slides.

[0110] Specifically, gaps may be provided between the first rack 132 and the sleeve 150 , and between the sleeve 150 and the first mounting column 114 , so as to reduce the friction resistance of the transmission assembly 130 and extend the service life of the transmission assembly 130 .

[0111] Specifically, there may be a plurality of first sliding grooves 134 , a plurality of shaft sleeves 150 , and a plurality of first mounting columns 114 equal in number to the shaft sleeves 150 are provided.

[0112] Among them, the number of first slide grooves 134 can be the same as the number of sleeves 150, and a corresponding sleeve 150 can be set in a first slide groove 134, so that any sleeve 150 among the multiple sleeves 150 is sleeved on the corresponding first mounting column 114 and located in a corresponding first slide groove 134, which can reduce friction and improve the stability of the structure.

[0113] The number of the first slide grooves 134 may be different from the number of the shaft sleeves 150, and then a plurality of shaft sleeves 150 may be arranged in one first slide groove 134, so that the friction resistance of the first rack 132 during the sliding process can be reduced, the friction resistance of the transmission assembly 130 can be increased, the flexibility of the transmission assembly 130 can be increased, the structural stability of the transmission assembly 130 can be further improved, and the service life of the transmission assembly 130 can be extended. Furthermore, two shaft sleeves 150 may be arranged in one first slide groove 134, or three shaft sleeves 150 may be arranged in one first slide groove 134, and the number of shaft sleeves 150 in one first slide groove 134 may be set according to the actual size of the transmission assembly 130.

[0114] Specifically, Figure 1 and Fig.13 As shown, by setting multiple sleeves 150 and cooperating with multiple first mounting columns 114 and multiple first slide grooves 134, the friction resistance encountered by the first rack 132 during the sliding process can be reduced, wherein the multiple sleeves 150 include a first sleeve 176 and a second sleeve 178, wherein the multiple first slide grooves 134 can include a first sub-groove 172 and a second sub-groove 174, the first sleeve 176 is set in the first slide groove 134, and the second sleeve 178 is set in the second sub-groove 174, when the drive assembly 140 is working, the transmission assembly 130 slides under the action of the driving force, and by setting the first sleeve 176 and the second sleeve 178 to cooperate with the first sub-groove 172 and the second sub-groove 174 respectively, the first sleeve 176 can slide relative to each other in the first sub-groove 172, and the second sleeve 178 can slide relative to each other in the second sub-groove 174, thereby improving the sliding smoothness of the transmission assembly 130, reducing the friction resistance, and extending the service life of the transmission assembly 130.

[0115] Specifically, the distance between the first sleeve 176 and the center point of the cover body 110 is greater than the distance between the second sleeve 178 and the center point of the cover body 110, thereby improving the stability of the transmission assembly 130 when sliding, reducing uneven force during the sliding process, thereby reducing friction resistance, and extending the service life of the transmission assembly 130.

[0116] This embodiment provides a cover assembly 100. In addition to the technical features of the above embodiments, this embodiment further includes the following technical features.

[0117] The driving assembly 140 includes a driving component 142 and a first gear 144 . The driving component 142 is disposed on the cover 110 . The first gear 144 is connected to an output shaft 143 of the driving component 142 , and the first gear 144 is meshed with the first rack 132 .

[0118] In this embodiment, the driving assembly 140 includes a driving component 142 and a first gear 144. The driving component 142 is disposed on the cover body 110. The first gear 144 is connected to the output shaft 143 of the driving component 142, and the first gear 144 is meshed with the first rack 132. The first gear 144 is driven by the output shaft 143 of the driving component 142 to rotate, and the rotating first gear 144 drives the first rack 132 to slide relative to the first mounting column 114, so that the transmission assembly 130 is driven by the driving assembly 140, and the structure of the driving assembly 140 screwed with the cover assembly 100 is simplified.

[0119] Specifically, the driving component 142 may be a motor.

[0120] This embodiment provides a cover assembly 100. In addition to the technical features of the above embodiments, this embodiment further includes the following technical features.

[0121] The locking component 120 includes a third body 122 and a second mounting post 124 . The second mounting post 124 is disposed through the cover 110 . A first end of the second mounting post 124 is connected to the first rack 132 , and a second end of the second mounting post 124 is connected to the third body 122 .

[0122] In this embodiment, the locking component 120 includes a third body 122 and a second mounting column 124, the second mounting column 124 is penetrated by the cover body 110, the first end of the second mounting column 124 is connected to the first rack 132, and the second end of the second mounting column 124 is connected to the third body 122. When the cover assembly 100 is rotated to open and close, the driving component 140 can drive the transmission component 130 to slide relative to the first mounting column 114. Since the first end of the second mounting column 124 is connected to the first rack 132, when the transmission component 130 slides, the second mounting column 124 is driven by the first rack 132. Since the second mounting column 124 is connected to the third body 122, the driving component 140 can drive the locking component 120 through the transmission component 130 to realize the rotation opening and closing of the cover assembly 100. Through the cooperation of the driving assembly 140 , the transmission assembly 130 and the locking component 120 , the structure of the rotating opening and closing device on the cover assembly 100 is simplified, thereby reducing the volume of the cover assembly 100 and reducing the production and installation cost of the cover assembly 100 .

[0123] In an embodiment of the present invention, a cooking appliance 200 is provided, comprising the cover assembly 100 in the above embodiment.

[0124] like Figure 8 As shown, this embodiment provides a cooking appliance 200. In addition to the technical features of the above embodiments, this embodiment further includes the following technical features.

[0125] The locking component 120 includes a plurality of first lock buckles 126, which are arranged at intervals along the circumference of the third body 122 of the locking component 120; the cooking utensil 200 also includes an inner pot 240, and a plurality of second lock buckles 242 are provided on the edge of the inner pot 240; wherein, when the locking component 120 is in the first position, the plurality of first lock buckles 126 are engaged with the plurality of second lock buckles 242; and when the locking component 120 is in the second position, the plurality of first lock buckles 126 are staggered with the plurality of second lock buckles 242.

[0126] In this embodiment, the locking member 120 includes a plurality of first lock buckles 126, which are arranged at intervals along the circumference of the third body 122 of the locking member 120; the cooking utensil 200 also includes an inner pot 240, and a plurality of second lock buckles 242 are arranged on the edge of the inner pot 240; wherein, when the locking member 120 is in the first position, the plurality of first lock buckles 126 are engaged with the plurality of second lock buckles 242, so that the cover body 110 can be in a locked state and the inner pot 240 can be closed; when the locking member 120 is in the second position, the plurality of first lock buckles 126 are staggered with the plurality of second lock buckles 242, so that the cover body 110 can be in an open state and the inner pot 240 can be opened. By arranging the plurality of first lock buckles 126 in the circumferential direction, a better locking effect can be achieved when the locking member 120 is in the locked state.

[0127] Specifically, the circumferential direction of the third body 122 is the direction indicated by the arrow G1.

[0128] Specifically, the number of the first locks 126 can be set according to actual needs of the cooking appliance 200 .

[0129] Specifically, the cooking appliance 200 may be an electric pressure cooker, a micro-pressure rice cooker, or the like.

[0130] In one embodiment of the present application, Fig. 9 As shown, the opening and closing cover structure of the cooking utensil includes a shell 310, an inner cover 322, an inner pot 320, a motor 330, a second gear 340, a second rack 350 and a lock 360, wherein the second rack 350 is provided with a connecting hole 352, and the lock 360 is provided with a connecting pin 362, wherein at least two components are gap connected.

[0131] In this embodiment, the second rack 350 is overlapped on the lock buckle 360, and the lock buckle 360 ​​is overlapped on the inner cover 322. The second rack 350 is provided with a connecting hole 352, and the lock buckle 360 ​​is provided with a connecting pin 362, and the connecting pin 362 is inserted into the connecting hole 352, wherein at least two components are connected with a gap. During the operation of the cooking utensil 200, the pressure in the inner pot 320 rises. Through the gap setting, the motor 330, the second gear 340, the second rack 350 and the lock buckle 360 ​​are prevented from being deformed due to the pressure of the inner pot 320, resulting in compression between the components, thereby improving the smoothness of the opening and closing cover structure, and preventing the motor 330 from getting stuck or locked due to the lack of idling distance when starting.

[0132] Specifically, during the process of opening the lid of the cooking utensil 200, the motor 330 rotates and drives the second gear 340 to rotate. Since the second gear 340 and the second rack 350 are meshingly connected, the second gear 340 drives the second rack 350 to slide, and then the connecting hole 352 on the second rack 350 moves with the rack, and the hole wall of the connecting hole 352 drives the connecting pin 362 to move, thereby realizing the movement of the lock 360.

[0133] Specifically, point F is the first braking position of the second rack 350 of the cooking appliance 200 .

[0134] Specifically, at least two components are gap connected, wherein the second rack 350 and the lock 360 can be gap connected, or the lock 360 and the inner cover 322 can be gap connected, or the second rack 350 and the lock 360, and the lock 360 and the inner cover 322 can be gap connected at the same time. By setting the gap, when the pressure inside the inner pot 320 of the cooking utensil 200 rises and causes the components to deform, reserving a gap at the connection can improve the smoothness of the movement of the second rack 350 and the lock 360.

[0135] In one embodiment of the present application, Fig.10 , Fig.11 and Fig.12 As shown, an axial hole is provided on the second rack, and the axial hole is gap-connected with the lock buckle, wherein the gap distance between the edge of the axial hole and the lock buckle is L1, and L1 is greater than or equal to 0.5 mm.

[0136] In this embodiment, an axial hole is provided on the second rack 350, and the axial hole and the lock buckle 360 ​​are gap connected, wherein the gap distance between the edge of the axial hole and the lock buckle 360 ​​is L1, and L1 can be greater than or equal to 0.5 mm to increase the gap, thereby preventing the lock buckle 360 ​​and the second rack 350 from being deformed due to the increase in pressure in the inner liner 320, causing the connection between the components to be stuck during operation, thereby avoiding the inability to open and close the inner cover 322 due to the increase in air pressure in the inner liner 320. At the same time, setting the gap L1 greater than or equal to 0.5 mm can facilitate the installation between components.

[0137] In one embodiment of the present application, the shaft hole is set to be long and narrow, which can leave an idling distance for the drive of the motor 330. At the same time, the gap L2 is set to L2 greater than or equal to 1 mm to avoid deformation of the device due to the pressure increase in the inner liner 320, which may cause the motor 330 to be stuck.

[0138] An idle distance may be preset for the driving gear of the motor 330 to avoid deformation of components due to increased pressure in the inner liner 320, which may cause the motor 330 to be affected by resistance during driving and cause the motor 330 to be stuck.

[0139] In one embodiment of the present application, the lock buckle 360 ​​and the second rack 350 are overlapped with each other with a gap, and the length of the gap is L3, which is greater than or equal to 1 mm.

[0140] In this embodiment, the lock buckle 360 ​​and the second rack 350 are connected with a gap overlap. Since an axial hole is provided on the rack, the second rack 350 is arranged parallel to the lock buckle 360 ​​and is arranged in the direction where the lock buckle 360 ​​is away from the inner liner 320. The overlap can improve the efficiency of the second rack 350 in transmitting the force to the lock buckle 360. At the same time, the length of the gap is L3, and L3 is greater than or equal to 1 mm. When the gas pressure in the inner liner 320 rises, the lock buckle 360 ​​is easily deformed due to the pressure. The width L3 of the gap reserved between the second rack 350 and the lock buckle 360 ​​is greater than or equal to 1 mm to avoid direct contact between the lock buckle 360 ​​and the second rack 350 after deformation, causing the movement of the second rack 350 to be subject to greater friction resistance, and at the same time avoid the large friction resistance causing the motor 330 to be driven and cause a malfunction.

[0141] In one embodiment of the present application, the lock buckle 360 ​​and the inner cover are connected with a gap overlap, and the overlap gap L4 is greater than or equal to 2 mm.

[0142] In this technical solution, an inner cover is arranged above the inner liner 320. When the air pressure inside the inner liner 320 rises, the inner cover 322 is easily deformed under the action of pressure. A gap is reserved between the inner cover 322 and the lock buckle 360 ​​to avoid excessive deformation of the inner cover 322, which may cause the lock buckle 360 ​​to be unable to cooperate with the inner cover 322 to achieve unlocking and closing. At the same time, the size of the gap is set to L4 greater than or equal to 2mm. Because the inner cover 322 is in direct contact with the inside of the inner liner 320 and is subjected to the greatest pressure, the inner cover 322 may be subject to a larger deformation. Therefore, setting L4 to greater than or equal to 2mm can avoid the inability to open and close the inner cover 322 due to the rising air pressure in the inner liner 320.
