[0007] The present application provides a cover assembly for a cooking utensil, the cooking utensil comprising a pot body, the cover assembly being coverable on the pot body, the cover assembly comprising a cover body, a locking component, an exhaust component, a valve body, a transmission component and a drive component. The cover body in the cover assembly can be buckled on the pot body, and the cover body and the pot body form a cooking space. The cover assembly is also provided with a locking component, which is connected to the cover body and can move relative to the cover body, and can cooperate with the pot body to seal the pot body. When the cooking utensil is working, the internal gas is heated, and the air pressure of the internal environment increases accordingly. The locking component, the exhaust component and the pot body cooperate with each other to improve the airtightness of the pot body, so that there is a certain pressure in the pot body, which can improve the cooking effect of the cooking utensil on food. At the same time, the locking of the pot body by the locking component can improve the safety of the cooking utensil when working. At the same time, the locking component is connected to the cover body and can move relative to the cover body, which is convenient for the opening and closing of the cooking utensil. An exhaust component is provided on the cover assembly. Since the first side of the exhaust component faces the pot body and can be connected to the pot body, when the cooking utensil is working, the exhaust component can exhaust the pot body, thereby adjusting the air pressure of the pot body of the cooking utensil and improving the cooking effect of the cooking utensil. At the same time, a valve body is provided in the cover assembly, and the valve body cover is provided on the second side of the exhaust component to open or close the exhaust component. The valve body can control the conduction or closing of the exhaust component, thereby controlling the exhaust condition of the cooking utensil. The cover assembly is also provided with a transmission component, which is connected to the locking component, thereby controlling the movement of the locking component relative to the pot body, and realizing the control of the locking state and unlocking state of the cover body. At the same time, the transmission component can drive the valve body to move relative to the exhaust component, so that the exhaust component is conducted or disconnected, realizing the control of the opening and closing of the valve body, thereby controlling the exhaust effect of the cooking utensil. Since the cover assembly is also provided with a driving assembly, the driving assembly is connected to the transmission assembly so as to drive the locking component to move through the transmission assembly and drive the valve body to move through the transmission assembly, thereby realizing opening or closing of the exhaust component. Therefore, the operation of the transmission assembly can be controlled by the driving action of the driving assembly so as to respectively control the exhaust component to be turned on or off, and also to control the locking component to lock or unlock the pot body, thereby making the exhaust device and the locking device use the same driving assembly and transmission assembly, simplifying the structure of the driving assembly and the transmission assembly, improving the integrity of the control device for controlling the exhaust component and the locking component, thereby reducing the volume of the cover assembly, reducing the production and installation cost of the cover assembly, and reducing the production and installation cost of the cooking appliance.

[0008] Furthermore, by providing a drive assembly and a transmission assembly that can simultaneously control the exhaust conditions of the locking component and the exhaust component, the structure of the drive device in the cover assembly is simplified, thereby reducing working noise and improving the user experience during use.

[0009] In addition, the cover assembly in the above technical solution provided by the utility model may also have the following additional technical features:

[0010] In some technical schemes of the utility model, optionally, the transmission assembly has a first position, a second position and a third position; when the transmission assembly is in the first position, the locking component is locked with the pot body, and the valve body closes the exhaust component; when the transmission assembly is in the second position, the locking component is locked with the pot body, and the valve body opens the exhaust component; when the transmission assembly is in the third position, the locking component is unlocked from the pot body; the driving assembly can drive the transmission assembly to move between the first position, the second position and the third position.

[0011] In this technical solution, the transmission assembly has a first position, a second position and a third position, and the opening and closing state of the locking component and the opening and closing state of the valve body to the exhaust component can be controlled by controlling the position of the transmission device; when the transmission assembly is in the first position, the locking component is locked with the pot body, and the valve body falls and snaps on the exhaust component, and then the valve body closes the exhaust component, the exhaust component is sealed, and the cooking utensil enters the working state to facilitate the cooking of food; when the transmission assembly is in the second position, the locking component is locked with the pot body, and the valve body moves up, and then the exhaust component is opened, so that the pot body is locked and the pot body is exhausted to adjust the air pressure inside the pot body; when the transmission assembly is in the third position, the locking component is unlocked from the pot body, and the user can open the pot body; since the driving assembly can drive the transmission assembly to the first position The first position, the second position and the third position can be moved between the first position and the second position, so the conduction or closing of the exhaust component and the opening and closing state of the cover body can be controlled simultaneously by the driving component. When the cooking appliance is working, the pot body can be locked and the exhaust component can be closed by the valve body. After the cooking of the cooking appliance is finished and the pot body is in a pressurized state, the lid body can be locked to exhaust and adjust the air pressure of the pot body. When the pot body pressure reaches the ambient pressure, the locked state of the pot body can be released. Therefore, by setting the first position, the second position and the third position of the transmission component and the control of the transmission device by the driving component, the coordination of the exhaust component and the locking component of the pot body can be improved, the opening method of the cover assembly can be enriched, and the volume of the cover assembly can be simplified, and the production and installation cost of the cover assembly can be reduced, thereby reducing the production and installation cost of the cooking appliance.

[0012] In some technical solutions of the utility model, optionally, the transmission assembly includes a rack having a first slide groove arranged on the rack; the cover body includes a first mounting column, the first mounting column is located in the first slide groove and can slide relative to the first slide groove; the driving assembly includes a driving component and a gear, the driving component is connected to the gear, and the gear is meshed with the rack.

[0013] In this technical solution, the transmission assembly includes a rack, and a first slide groove is arranged on the rack; the cover body includes a first mounting column, and the first mounting column is located in the first slide groove and can slide relative to the first slide groove; the driving assembly includes a driving component and a gear. Since the driving component is connected to the gear, the driving component can drive the gear to rotate, and at the same time, through the meshing of the gear and the rack, the rotation of the gear can drive the rack to move, and then the transmission assembly moves along with the rotation of the gear. Since the first mounting column arranged on the cover body is located in the first slide groove, and the first slide groove is arranged on the rack, when the rack moves, the movement trajectory of the rack can be limited by the first mounting column, and the movement of the rack can drive the valve body to open and close the exhaust component. At the same time, the movement of the rack can also control the state of the locking component to realize sliding unlocking and exhaust.

[0014] Specifically, the driving component drives the rack to slide through the gear, the first slide slot slides relative to the first mounting column, and then the transmission component slides relative to the first mounting column. When the transmission component moves to the first position, the rack controls the locking component to lock the pot body, and the rack controls the valve body to close the exhaust component. When the transmission component moves to the second position, the rack controls the valve body to open the exhaust component, at which time the locking component is still in a locked state, and the pot body is exhausted. When the transmission component moves to the third position, the rack controls the locking component to be in an unlocked state.

[0015] Specifically, the first mounting post is arranged on the cover body, and the position of the first mounting post remains unchanged. When the transmission assembly is working, the rack moves relative to the first mounting post.

[0016] Specifically, the driving component may be a motor.

[0017] In some technical solutions of the utility model, optionally, the rack is provided with a second slide groove, and the second slide groove is arranged in parallel with the first slide groove along the sliding direction of the rack; the locking component includes a second mounting column, and the second mounting column is arranged in the second slide groove and can slide in the second slide groove.

[0018] In this technical solution, the rack is provided with a second slide groove, and the second slide groove is arranged in parallel with the first slide groove along the sliding direction of the rack; the locking component includes a second mounting column, and the second mounting column is arranged in the second slide groove and can slide in the second slide groove. When the rack is located at the second position, there is a sliding distance between the second slide groove and both sides of the second mounting column. At this time, the locking component is still in a locked state, but the transmission assembly controls the valve body to open the exhaust component to exhaust the pot body, and then the exhaust can be achieved before the locking component is opened, thereby improving the safety of the cooking appliance and the mutual coordination between the exhaust of the exhaust component and the unlocking of the locking component in the cooking appliance.

[0019] Specifically, the driving component drives the rack to slide through the gear, the first slide groove slides relative to the first mounting column, and then the transmission component slides relative to the first mounting column. When the transmission component moves to the first position, the rack slides, driving the second mounting column in the second slide groove, and then driving the locking component to enter the locked state, and the rack controls the valve body to close the exhaust component. When the transmission component moves to the second position, the rack moves to the second position with the transmission component, and the second slide groove has no transmission effect on the second mounting column. At this time, the locking component is still in the locked state, and the rack controls the valve body to open the exhaust component, so as to exhaust the pot body before the locking component is in the unlocked state. When the transmission component moves to the third position, the rack controls the second mounting column in the second slide groove by sliding itself. Since the second mounting column is set in the locking component, the rack rotates the locking component to control the locking component to be in the unlocked state.

[0020] In some technical solutions of the utility model, optionally, the transmission assembly also includes a connecting rod and a driving block, the connecting rod is rotatably connected to the cover body, and the first end of the connecting rod is connected to the rack; the driving block is connected to the second end of the connecting rod and can lift the valve body.

[0021] In this technical solution, the transmission assembly also includes a connecting rod and a driving block. The connecting rod is rotatably connected to the cover body. The first end of the connecting rod is connected to the rack. The connecting rod rotates relative to the cover body along with the movement of the rack. The driving block is connected to the second end of the connecting rod. The driving block moves relatively with the rotation of the connecting rod. After the driving block moves to the bottom of the valve body, it can lift up the valve body and control the valve body to open the exhaust component to exhaust the pot body. Through the setting of the connecting rod and the driving block, the position of the valve body can be controlled by the transmission assembly, and then the opening or closing state of the exhaust component can be controlled, the structure of the control device can be simplified, the production and installation cost of the cover assembly can be saved, the driving of the valve body can be facilitated, and the cooking appliance can be conveniently controlled to exhaust.

[0022] Specifically, the driving component drives the transmission assembly to slide through gears. Since the connecting rod is connected to the transmission assembly, the connecting rod is displaced along with the sliding of the transmission assembly. When the transmission assembly is in the first position, the connecting rod is displaced, and the driving block is displaced while being connected to the connecting rod. The driving block moves away from the valve body, and controls the valve body to close the exhaust component. When the transmission assembly is in the second position, the driving block moves to the bottom of the valve body along with the sliding of the transmission assembly and the connecting rod, and squeezes the valve body upward, and controls the valve body to open the exhaust component, thereby exhausting the pot body.

[0023] Specifically, the valve body is buckled above the exhaust component, and the exhaust component is closed by the valve body's own gravity. The movement trajectory of the drive block overlaps with the position of the valve body when it is buckled on the exhaust component. When the drive block moves to the valve body, the drive block squeezes the valve body to move the valve body upward, and then the exhaust component is turned on to exhaust the pot body. When the drive block is away from the valve body, the valve body falls by its own gravity to close the exhaust component. By controlling the up and down position of the valve body by the drive block, the structure of the device for controlling the conduction or closing of the exhaust component can be simplified, thereby simplifying the structure of the cover assembly and reducing the production and installation cost of the cover assembly.

[0024] Furthermore, since the drive block is provided to control the valve body to open or close the exhaust component to reduce the volume of the control device, the volume of the exhaust component can be relatively increased, thereby increasing the exhaust space while ensuring that the overall volume remains unchanged, improving the exhaust efficiency of the cooking appliance, and enhancing the user experience when using it.

[0025] In some technical solutions of the present utility model, optionally, the driving block is arranged to be inclined toward the side wall of the valve body relative to the side wall of the valve body.

[0026] In this technical solution, the side wall of the driving block facing the valve body is inclined relative to the side wall of the valve body. When the driving block moves toward the valve body, the inclined side wall of the driving block facilitates the driving block to lift the valve body upward. The inclined side wall can reduce the resistance during the relative movement between the driving block and the valve body, making the valve body move upward more smoothly.

[0027] In some technical solutions of the utility model, optionally, the cover body includes a third mounting column, the connecting rod includes a mounting part, a first connecting part and a second connecting part, and the mounting part is sleeved on the third mounting column; the first end of the first connecting part is connected to the mounting part, and the second end of the first connecting part is connected to the rack; the first end of the second connecting part is connected to the mounting part, and the second end of the second connecting part is connected to the driving block.

[0028] In this technical solution, the cover body includes a third mounting column, and the connecting rod includes a mounting part, a first connecting part and a second connecting part. The mounting part is sleeved on the third mounting column, and the mounting part can rotate on the third mounting column; the first end of the first connecting part is connected to the mounting part, and the second end of the first connecting part is connected to the rack; the first end of the second connecting part is connected to the mounting part, and the second end of the second connecting part is connected to the driving block. Through the connection of the mounting part, the first connecting part and the second connecting part can rotate relative to the third mounting column under the drive of the transmission assembly, thereby realizing the control of the upward movement and downward movement of the valve body through the connecting rod, and then controlling the valve body to open and close the exhaust component, thereby improving the integrity of the control device for controlling the exhaust component and the locking component, thereby simplifying the volume of the cover assembly, reducing the production and installation cost of the cover assembly, and reducing the production and installation cost of the cooking appliance.

[0029] Specifically, the driving component drives the transmission assembly to slide through the gear. Since the connecting rod is connected to the transmission assembly, the first connecting part and the second connecting part on the connecting rod rotate relative to the third mounting column under the drive of the transmission assembly. When the transmission assembly is in the first position, due to the rotation of the connecting rod, the driving block is connected to the second end of the second connecting part of the connecting rod, and the driving block moves to a position away from the valve body, controlling the valve body to close the exhaust component. When the transmission assembly moves to the second position, the driving block on the second end of the second connecting part of the connecting rod moves to the bottom of the valve body, and the valve body is squeezed and moved upward, controlling the valve body to open the exhaust component to exhaust the pot body.

[0030] In some technical solutions of the utility model, optionally, the rack is provided with a mounting groove, the mounting groove has an opening, the opening faces the connecting rod, and the connecting rod further includes a fourth mounting column, and the fourth mounting column is embedded in the mounting groove.

[0031] In this technical solution, the rack is provided with a mounting groove, the mounting groove has an opening, the opening faces the connecting rod, and the connecting rod also includes a fourth mounting column, and the fourth mounting column is embedded in the mounting groove. Therefore, by embedding the fourth mounting column in the mounting groove, the connection between the rack and the connecting rod is realized, and then the transmission of the connecting rod is realized, which facilitates the transmission of the connecting rod through the rack, and then controls the opening and closing of the exhaust component by the valve body, thereby simplifying the volume of the cover assembly, reducing the production and installation cost of the cover assembly, and reducing the production and installation cost of the cooking appliance.

[0032] In some technical solutions of the present utility model, optionally, a first angle is defined between the first connection portion and the second connection portion, and the first angle is greater than or equal to 90 degrees and less than or equal to 180 degrees.

[0033] In this technical solution, a first angle is defined between the first connection portion and the second connection portion, and the first angle is greater than or equal to 90 degrees and less than or equal to 180 degrees. By setting the first angle between 90 and 180 degrees, the total length of the first connection portion and the second connection portion is reduced, thereby reducing the space occupied by the connecting rod and facilitating the production and installation of the cover assembly.

[0034] In some technical solutions of the present utility model, optionally, the drive assembly is located on a side of the transmission assembly away from the exhaust component.

[0035] In this technical solution, the drive assembly is located on the side of the transmission assembly away from the exhaust component, so the drive assembly can be placed reasonably to improve the utilization rate of the space inside the cover assembly.

[0036] Furthermore, the shape of the cover assembly of the cooking utensil can be square. Since the shape of the cover body is circular, a gap is left between the edge of the cover body and the edge of the cover assembly. The drive assembly is arranged in the gap, which can reasonably utilize the internal space of the cover assembly without affecting the installation of the cover body, thereby reducing the production and installation cost of the cover assembly.

[0056] The present application provides a cover assembly 100, which is used for a cooking utensil 200, and the cooking utensil 200 includes a pot body 210.

[0057] Furthermore, by providing a drive assembly 160 and a transmission assembly 150 that can simultaneously control the exhaust conditions of the locking component 120 and the exhaust component 130, the structure of the drive device in the cover assembly 100 is simplified, thereby reducing working noise and improving the user experience during use.

[0058] 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.

[0059] like Figure 2 , Figure 3 , Figure 4 and Figure 7 As shown, the transmission assembly 150 has a first position, a second position and a third position; when the transmission assembly 150 is in the first position, the locking component 120 is locked with the pot body 210, and the valve body 140 closes the exhaust component 130; when the transmission assembly 150 is in the second position, the locking component 120 is locked with the pot body 210, and the valve body 140 opens the exhaust component 130; when the transmission assembly 150 is in the third position, the locking component 120 is unlocked from the pot body 210; the driving assembly 160 can drive the transmission assembly 150 to move between the first position, the second position and the third position.

[0060] Specifically, Figure 2 As shown, the first position is S1;

[0061] like Figure 3 As shown, the second position is S2;

[0062] like Figure 4 As shown, the third position is S3.

[0063] In this embodiment, the transmission assembly 150 has a first position, a second position and a third position, and the opening and closing state of the locking component 120 and the opening and closing state of the exhaust component 130 by the valve body 140 can be controlled by controlling the position of the transmission device; when the transmission assembly 150 is in the first position, the locking component 120 is locked with the pot body 210, and the valve body 140 falls and engages with the exhaust component 130, and then the valve body 140 closes the exhaust component 130, the exhaust component 130 is sealed, and the cooking utensil 200 is Entering the working state is convenient for cooking food; when the transmission assembly 150 is in the second position, the locking component 120 and the pot body 210 are locked, and the valve body 140 moves up, thereby opening the exhaust component 130, locking the pot body 210 and exhausting the pot body 210 to adjust the internal air pressure of the pot body 210; when the transmission assembly 150 is in the third position, the locking component 120 and the pot body 210 are unlocked, and the user can open the pot body 210; because the driving assembly 160 can drive the transmission assembly 1 50 moves among the first position, the second position and the third position, so the conduction or closing of the exhaust component 130 and the opening and closing state of the cover body 110 can be controlled simultaneously by the driving component 160. When the cooking utensil 200 is working, the pot body 210 can be locked, and the exhaust component 130 can be closed by the valve body 140. It is also possible to lock the cover body 110 and exhaust and adjust the air pressure of the pot body 210 when the pot body 210 is in a pressurized state after the cooking of the cooking utensil 200 is finished. When the pressure of the pot body 210 reaches the ambient pressure, the locked state of the pot body 210 can be contacted. Therefore, by setting the first position, the second position and the third position of the transmission component 150 and the control of the transmission device by the driving component 160, the coordination of the exhaust component 130 and the locking component 120 of the pot body 210 can be improved, the opening method of the cover assembly 100 can be enriched, and the volume of the cover assembly 100 can be simplified, and the production and installation cost of the cover assembly 100 can be reduced, thereby reducing the production and installation cost of the cooking utensil 200.

[0064] 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.

[0065] like Figure 2 , Figure 3 and Figure 4 As shown, the transmission assembly 150 includes a rack 152, and a first slide groove 1522 is arranged on the rack 152; the cover body 110 includes a first mounting column 112, and the first mounting column 112 is located in the first slide groove 1522 and can slide relative to the first slide groove 1522; the driving assembly 160 includes a driving component 162 and a gear 164, the driving component 162 is connected to the gear 164, and the gear 164 is meshed with the rack 152.

[0066] In this embodiment, the transmission assembly 150 includes a rack 152, and a first slide groove 1522 is provided on the rack 152; the cover body 110 includes a first mounting column 112, and the first mounting column 112 is located in the first slide groove 1522 and can slide relative to the first slide groove 1522; the driving assembly 160 includes a driving component 162 and a gear 164. Since the driving component 162 is connected to the gear 164, the driving component 162 can drive the gear 164 to rotate, and at the same time, the gear 164 is meshed with the rack 152, and the rotation of the gear 164 can drive the rack 152 to move. Then, the transmission assembly 150 moves along with the rotation of the gear 164. Since the first mounting column 112 arranged on the cover body 110 is located in the first slide groove 1522, and the first slide groove 1522 is arranged on the rack 152, when the rack 152 moves, the movement trajectory of the rack 152 can be limited by the first mounting column 112. The movement of the rack 152 can drive the valve body 140 to open and close the exhaust component 130. At the same time, the movement of the rack 152 can also control the state of the locking component 120 to achieve sliding unlocking and exhaust.

[0067] Specifically, the driving component 162 drives the rack 152 to slide through the gear 164, and the first slide groove 1522 slides relative to the first mounting column 112, and then the transmission assembly 150 slides relative to the first mounting column 112. When the transmission assembly 150 moves to the first position, the rack 152 controls the locking component 120 to lock the pot body 210, and the rack 152 controls the valve body 140 to close the exhaust component 130. When the transmission assembly 150 moves to the second position, the rack 152 controls the valve body 140 to open the exhaust component 130, at which time the locking component 120 is still in a locked state, and the pot body 210 is exhausted. When the transmission assembly 150 moves to the third position, the rack 152 controls the locking component 120 to be in an unlocked state.

[0068] Specifically, the first mounting post 112 is disposed on the cover body 110 , and the position of the first mounting post 112 remains unchanged. When the transmission assembly 150 is working, the rack 152 moves relative to the first mounting post 112 .

[0069] 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.

[0070] like Figure 2 , Figure 3 and Figure 4 As shown, the rack 152 is provided with a second slide groove 1524, and the second slide groove 1524 and the first slide groove 1522 are arranged in parallel along the sliding direction of the rack 152; the locking component 120 includes a second mounting column 122, and the second mounting column 122 is arranged in the second slide groove 1524 and can slide in the second slide groove 1524.

[0071] In this embodiment, the rack 152 is provided with a second slide groove 1524, and the second slide groove 1524 is arranged in parallel with the first slide groove 1522 along the sliding direction of the rack 152; the locking component 120 includes a second mounting column 122, and the second mounting column 122 is arranged in the second slide groove 1524 and can slide in the second slide groove 1524. When the rack 152 is located at the second position, there is a sliding distance between the second slide groove 1524 and the second mounting column 122 on both sides. At this time, the locking component 120 is still in a locked state, but the transmission assembly 150 controls the valve body 140 to open the exhaust component 130 to exhaust the pot body 210, and then exhaust can be achieved before the locking component 120 is opened, thereby improving the safety of the cooking utensil 200 and the mutual coordination between the exhaust of the exhaust component 130 and the unlocking of the locking component 120 in the cooking utensil 200.

[0072] Specifically, the driving component 162 drives the rack 152 to slide via the gear 164, and the first slide groove 1522 slides relative to the first mounting column 112, and then the transmission assembly 150 slides relative to the first mounting column 112. When the transmission assembly 150 moves to the first position, the rack 152 slides, driving the second mounting column 122 in the second slide groove 1524, and then driving the locking component 120 to enter a locked state, and the rack 152 controls the valve body 140 to close the exhaust component 130. When the transmission assembly 150 moves to the second position, the rack 152 moves to the second position with the transmission assembly 150, and the second slide groove 1524 has no transmission effect on the second mounting column 122. At this time, the locking component 120 is still in a locked state, and the rack 152 controls the valve body 140 to open the exhaust component 130, so as to exhaust the pot body 210 before the locking component 120 is in an unlocked state. When the transmission assembly 150 moves to the third position, the rack 152 controls the second mounting column 122 in the second slide groove 1524 by its own sliding. Since the second mounting column 122 is set in the locking component 120, the rack 152 rotates the locking component 120 to control the locking component 120 to be in an unlocked state.

[0073] 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.

[0074] like Figure 1 As shown, the transmission assembly 150 also includes a connecting rod 154 and a driving block 156 . The connecting rod 154 is rotatably connected to the cover body 110 , and the first end of the connecting rod 154 is connected to the rack 152 ; the driving block 156 is connected to the second end of the connecting rod 154 and can lift the valve body 140 .

[0075] In this embodiment, the transmission assembly 150 further includes a connecting rod 154 and a driving block 156. The connecting rod 154 is rotatably connected to the cover body 110. The first end of the connecting rod 154 is connected to the rack 152. The connecting rod 154 rotates relative to the cover body 110 as the rack 152 moves. The driving block 156 is connected to the second end of the connecting rod 154. The driving block 156 moves relatively as the connecting rod 154 rotates. After the driving block 156 moves to the bottom of the valve body 140, the valve body 140 can be lifted up to control the valve body 140 to open the exhaust component 130 and exhaust the pot body 210. Through the arrangement of the connecting rod 154 and the driving block 156, the position of the valve body 140 can be controlled by the transmission assembly 150, and then the opening or closing state of the exhaust component 130 can be controlled, the structure of the control device can be simplified, the production and installation cost of the cover assembly 100 can be saved, the driving of the valve body 140 can be facilitated, and the cooking utensil 200 can be conveniently controlled to exhaust.

[0076] Specifically, the driving component 162 drives the transmission assembly 150 to slide through the gear 164. Since the connecting rod 154 is connected to the transmission assembly 150, the connecting rod 154 is displaced along with the sliding of the transmission assembly 150. When the transmission assembly 150 is in the first position, the connecting rod 154 is displaced, and the driving block 156 is displaced while being connected to the connecting rod 154. The driving block 156 moves away from the valve body 140, and the valve body 140 is controlled to close the exhaust component 130. When the transmission assembly 150 is in the second position, the driving block 156 moves to the bottom of the valve body 140 along with the sliding of the transmission assembly 150 and the connecting rod 154, and the valve body 140 is squeezed upward, and the valve body 140 is controlled to open the exhaust component 130, thereby achieving the exhaust of the pot body 210.

[0077] Specifically, the valve body 140 is buckled on the exhaust component 130, and the exhaust component 130 is closed by the self-weight of the valve body 140. The movement trajectory of the driving block 156 overlaps with the position of the valve body 140 when it is buckled on the exhaust component 130. When the driving block 156 moves to the valve body 140, the driving block 156 squeezes the valve body 140, so that the valve body 140 moves upward, and then the exhaust component 130 is turned on, and the pot body 210 is exhausted. When the driving block 156 is away from the valve body 140, the valve body 140 falls by its own gravity and closes the exhaust component 130. By controlling the up and down position of the valve body 140 by the driving block 156, the structure of the device for controlling the conduction or closing of the exhaust component 130 can be simplified, thereby simplifying the structure of the cover assembly 100 and reducing the production and installation cost of the cover assembly 100.

[0078] Furthermore, since the drive block 156 is provided to control the valve body 140 to open or close the exhaust component 130 to reduce the volume of the control device, the volume of the exhaust component 130 can be relatively increased, thereby increasing the exhaust space while ensuring that the overall volume remains unchanged, thereby improving the exhaust efficiency of the cooking appliance 200 and enhancing the user experience when using it.

[0079] Specifically, the driving block 156 may be a rocker.

[0080] 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.

[0081] like Figure 1 As shown, the driving block 156 is disposed obliquely relative to the side wall of the valve body 140 toward the side wall of the valve body 140 .

[0082] In this embodiment, the side wall of the driving block 156 facing the valve body 140 is inclined relative to the side wall of the valve body 140. When the driving block 156 moves toward the valve body 140, the inclined side wall of the driving block 156 facilitates the driving block 156 to lift the valve body 140 upward. The inclined side wall can reduce the resistance during the relative movement between the driving block 156 and the valve body 140, thereby allowing the valve body 140 to move upward more smoothly.

[0083] 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.

[0084] like Figure 2 , Figure 3 and Figure 4 As shown, the cover body 110 includes a third mounting column 114, and the connecting rod 154 includes a mounting portion 1542, a first connecting portion 1543 and a second connecting portion 1544, and the mounting portion 1542 is sleeved on the third mounting column 114; the first end of the first connecting portion 1543 is connected to the mounting portion 1542, and the second end of the first connecting portion 1543 is connected to the rack 152; the first end of the second connecting portion 1544 is connected to the mounting portion 1542, and the second end of the second connecting portion 1544 is connected to the driving block 156.

[0085] In this embodiment, the cover 110 includes a third mounting post 114, and the connecting rod 154 includes a mounting portion 1542, a first connecting portion 1543, and a second connecting portion 1544. The mounting portion 1542 is sleeved on the third mounting post 114, and the mounting portion 1542 can rotate on the third mounting post 114; the first end of the first connecting portion 1543 is connected to the mounting portion 1542, and the second end of the first connecting portion 1543 is connected to the rack 152; the first end of the second connecting portion 1544 is connected to the mounting portion 1542, and the second end of the second connecting portion 1544 is connected to the driving block 15 6 connection, through the connection of the mounting portion 1542, the first connecting portion 1543 and the second connecting portion 1544 can rotate relative to the third mounting column 114 under the drive of the transmission assembly 150, thereby realizing the control of the upward movement and downward movement of the valve body 140 through the connecting rod 154, and then controlling the valve body 140 to open and close the exhaust component 130, thereby improving the integrity of the control device for controlling the exhaust component 130 and the locking component 120, thereby simplifying the volume of the cover assembly 100, reducing the production and installation cost of the cover assembly 100, and reducing the production and installation cost of the cooking appliance 200.

[0086] Specifically, the driving component 162 drives the transmission assembly 150 to slide through the gear 164. Since the connecting rod 154 is connected to the transmission assembly 150, the first connecting part 1543 and the second connecting part 1544 on the connecting rod 154 rotate relative to the third mounting column 114 under the drive of the transmission assembly 150. When the transmission assembly 150 is in the first position, due to the rotation of the connecting rod 154, the driving block 156 is connected to the second end of the second connecting part 1544 of the connecting rod 154, and the driving block 156 moves to a position away from the valve body 140, controlling the valve body 140 to close the exhaust component 130. When the transmission assembly 150 moves to the second position, the driving block 156 on the second end of the second connecting part 1544 of the connecting rod 154 moves to the bottom of the valve body 140, and the valve body 140 is squeezed and moves upward, controlling the valve body 140 to open the exhaust component 130 to exhaust the pot body 210.

[0087] 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.

[0088] like Figure 1 As shown, the rack 152 is provided with a mounting groove 1526 , and the mounting groove 1526 has an opening 1528 , and the opening 1528 faces the connecting rod 154 . The connecting rod 154 further includes a fourth mounting column 1545 , and the fourth mounting column 1545 is embedded in the mounting groove 1526 .

[0089] In this embodiment, the rack 152 is provided with a mounting groove 1526, and the mounting groove 1526 has an opening 1528, and the opening 1528 faces the connecting rod 154. The connecting rod 154 also includes a fourth mounting column 1545, and the fourth mounting column 1545 is embedded in the mounting groove 1526. Therefore, by embedding the fourth mounting column 1545 in the mounting groove 1526, the connection between the rack 152 and the connecting rod 154 is achieved, and then the transmission of the connecting rod 154 is achieved, which facilitates the transmission of the connecting rod 154 through the rack 152, and then controls the opening and closing of the exhaust component 130 by the valve body 140, thereby simplifying the volume of the cover assembly 100, reducing the production and installation cost of the cover assembly 100, and reducing the production and installation cost of the cooking appliance 200.

[0090] Specifically, the mounting groove 1526 may be a U-shaped groove to facilitate the installation of the fourth mounting column 1545 .

[0091] 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.

[0092] like Figure 5 As shown, a first angle is defined between the first connection portion 1543 and the second connection portion 1544 , and the first angle is greater than or equal to 90 degrees and less than or equal to 180 degrees.

[0093] In this embodiment, a first angle is defined between the first connection portion 1543 and the second connection portion 1544. The first angle is greater than or equal to 90 degrees and less than or equal to 180 degrees. By setting the first angle between 90 and 180 degrees, the total length of the first connection portion 1543 and the second connection portion 1544 is reduced, thereby reducing the space occupied by the connecting rod 154 and facilitating the production and installation of the cover assembly 100.

[0094] like Figure 5 As shown, the first angle is R, and the angle of R can be specifically:

[0095] R=90 degrees, R=120 degrees, R=150 degrees, R=180 degrees.

[0096] like Figure 1 As shown, 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.

[0097] The driving assembly 160 is located on a side of the transmission assembly 150 away from the exhaust component 130 .

[0098] In this embodiment, the driving assembly 160 is located on a side of the transmission assembly 150 away from the exhaust component 130 , so that the driving assembly 160 can be reasonably placed to improve the utilization rate of the space inside the cover assembly 100 .

[0099] Furthermore, the shape of the cover assembly 100 of the cooking utensil 200 can be square. Since the shape of the cover body 110 is circular, a gap is left between the edge of the cover body 110 and the edge of the cover assembly 100. The drive assembly 160 is arranged in the gap. The internal space of the cover assembly 100 can be reasonably utilized without affecting the installation of the cover body 110, thereby reducing the production and installation cost of the cover assembly 100.

[0100] like Figure 7 As shown, in an embodiment of the present invention, a cooking appliance 200 is provided, comprising the cover assembly 100 of any one of the above embodiments.

[0101] 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.

[0102] like Figure 6 and Figure 7 As shown, the locking component 120 includes a first body 124 and a plurality of first lock buckles 126, and the plurality of first lock buckles 126 are arranged at intervals along the circumference of the first body 124; the pot body 210 is provided with a plurality of second lock buckles 214; wherein, when the transmission assembly 150 is in the first position or the second position, the plurality of first lock buckles 126 are engaged with the plurality of second lock buckles 214; and when the transmission assembly 150 is in the third position, the plurality of first lock buckles 126 are staggered with the plurality of second lock buckles 214.

[0103] In this embodiment, the locking component 120 includes a first body 124 and a plurality of first lock buckles 126, and the plurality of first lock buckles 126 are arranged at intervals along the circumference of the first body 124; the pot body 210 is provided with a plurality of second lock buckles 214; wherein, when the transmission assembly 150 is in the first position or the second position, the plurality of first lock buckles 126 are engaged with the plurality of second lock buckles 214, and at this time, through the engagement of the plurality of first lock buckles 126 and the plurality of second lock buckles 214, the cover body 110 and the pot body 210 are in a locked state, and the user cannot open them; when the transmission assembly 150 is in the third position, the plurality of first lock buckles 126 and the plurality of second lock buckles 214 are staggered, and at this time, the cover body 110 and the pot body 210 are in an open state, and can be opened and closed at will, and the first lock buckles 126 and the second lock buckles 214 circumferentially of the first body 124 can cooperate with each other to realize the locking and opening modes of the pot body 210, thereby improving the safety of the cooking utensil 200 during operation and enhancing the user's experience during use.

[0104] Specifically, the cooking utensil 200 may be provided with an inner pot 212 and a pot body 210, wherein the second lock buckle 214 may be provided on the pot body 210, and the first lock buckle 126 of the locking component 120 may cooperate with the second lock buckle 214 on the pot body 210 to achieve the engagement and separation of the lid assembly 100 and the pot body 210. The user may choose to adjust the position of the locking component 120 according to the usage scenario and actual cooking steps to achieve the first lock buckle 126 moving to a state of mutual engagement or separation with the second lock buckle 214. Specifically, the cooking utensil 200 may be provided with only the pot body 210, that is, the inner pot 212 and the pot body 210 are an integrated structure, which can reduce costs and improve internal stability.

[0105] Furthermore, the second lock 214 can be provided on the inner pot 212, and the inner pot 212 and the pot body 210 can be separated from each other. When the cooking utensil 200 is working, the user can place the inner pot 212 in the pot body 210, and then snap the lid assembly 100 to drive the locking component 120 to the first position, so that the first lock 126 and the second lock 214 on the inner pot 212 are snapped together, thereby completing the snapping of the lid assembly 100. Since the second lock 214 is provided on the inner pot 212, when the inner pot 212 is not provided in the pot body 210, even if the lid assembly 100 is covered on the cooking utensil 200, the user cannot snap the lid assembly 100 and the cooking utensil 200 together, which can prevent the user from operating the cooking utensil 200 without placing the inner pot 212, and can remind the user to improve the safety of the cooking utensil 200 and facilitate use.

[0106] Specifically, the cooking device 200 may be an electric pressure cooker.

[0107] Furthermore, if Figure 7 As shown, the inner pot 212 can be independently arranged relative to the pot body 210, or can be integrated with the pot body 210.

[0108] Specifically, the inner pot 212 may be an inner pot.
