[0001] The utility model relates to the field of household appliances, in particular to a pot cover and cooking utensil. BACKGROUND

[0002] Some cooking utensils, the pot cover on usually will be equipped with the air hole, realizes the air pressure balance inside and outside the cooking utensil. The pot cover only with the air hole, because it cannot keep a certain air pressure in the cooking utensil, is inconvenient for quick cooking.

[0003] In order to reach the purpose of quick cooking, the micro-pressure pot cover exists on the market currently, and the micro-pressure valve on the micro-pressure pot cover is controlled by holding the pot cover handle, and the user needs to continuously exert force on the pot cover during the control process to make the micro-pressure valve remain in the normally open state, which is inconvenient to operate. UTILITY MODEL CONTENTS

[0004] Therefore, it is necessary to provide a pot cover and cooking utensil to facilitate user control of the micro-pressure valve.

[0005] The utility model provides a pot cover first, include: cover, be equipped with the exhaust hole on the cover, handle, install in the cover, the handle includes seat and the handle that is equipped in the seat, the seat has the exhaust cavity that communicates with the exhaust hole, be equipped with the limiting portion on the handle, the limiting portion includes first limiting portion and second limiting portion, pressure relief valve, be equipped in the exhaust cavity liftably, is used for controlling the exhaust hole opening and closing, and push mechanism, movably be equipped in the handle and with the pressure relief valve drive connection is used for driving the pressure relief valve lifts, be equipped with the cooperation portion on the push mechanism, when push mechanism moves to the cooperation portion with First limiting portion cooperation then pressure relief valve is in the state of lifting, when push mechanism moves to the cooperation portion with Second limiting portion cooperation then pressure relief valve is in the liftable state.

[0006] The user can control the movement of the pushing mechanism relative to the handle to change the state of the pressure relief valve in the exhaust cavity. When the pushing mechanism moves to the position where the fitting part cooperates with the second limiting part, the pressure relief valve in the exhaust cavity can freely rise and fall according to the pressure in the pot. When the gas pressure in the pot is lower than the gravity of the pressure relief valve, the pressure relief valve is lowered to close the exhaust hole, and the gas in the pot body cannot be discharged through the exhaust hole, thereby increasing the gas pressure in the pot body. When the gas pressure in the pot is greater than the gravity of the pressure relief valve, the gas can rush out by opening the pressure relief valve, so that the pot is maintained in a state of micro-pressure, realizing fast cooking. When the pushing mechanism moves to the position where the fitting part cooperates with the first limiting part, the pressure relief valve in the exhaust cavity remains in the raised state, and the gas in the pot body can be discharged through the exhaust hole and the exhaust cavity in turn, realizing cooking in the normal pressure working state. By cooperating the fitting part with the first limiting part or the second limiting part, the pushing mechanism can be stably positioned at the current position without external force, so that the pressure relief valve can be stably positioned in the raised state or the freely rising and falling state, without the user continuously holding the pushing mechanism, facilitating the user operation, and also preventing the user from being scalded by the high-temperature gas discharged from the exhaust hole.

[0007] In one of the embodiments, one of the limiting part and the fitting part is a deformable protrusion, and the other is a limiting groove, and the protrusion is clamped with the limiting groove.

[0008] In this way, when the user applies an external force to the pushing mechanism, the protrusion can be deformed and disengaged from the limiting groove. After the protrusion is clamped into the limiting groove, it can be reset to ensure the stability and reliability of the fitting part and the limiting part in the cooperating state.

[0009] In one of the embodiments, the pushing mechanism includes a force applying assembly and a top piece. The force applying assembly is provided with the fitting part. The top piece is rotatably arranged around a first axis. The top piece includes a top rod part and a force receiving part located on both sides of the first axis. The top rod part is drivingly connected with the pressure relief valve. The force receiving part abuts against the force applying assembly.

[0010] In this way, when the top rod part is turned upward, it can drive the pressure relief valve to rise in the exhaust cavity to open the exhaust hole. When the top rod part is turned downward, the pressure relief valve can descend in the exhaust cavity to close the exhaust hole.

[0011] In one of the embodiments, the pushing mechanism further includes a fixing seat. The fixing seat is fixedly arranged on the outer wall of the exhaust cavity and is provided with a rotating fitting part. The top piece further includes a rotating part and an annular connecting part. The rotating part is arranged on the connecting part. The top rod part and the force receiving part are respectively located on both sides of the rotating part. The rotating part is rotatably connected with the rotating fitting part. The axis of the rotating part is the first axis.

[0012] In this way, the fixing seat is used to support the top piece, so that the top piece can rotate around the first axis through the rotating part, and the connecting part can be sleeved outside the exhaust cavity, so that the space occupied by the top piece can be reduced, and the volume of the seat body is avoided to be increased.

[0013] In one of the embodiments, the handle further has an assembly cavity outside the exhaust cavity, and the push mechanism is arranged in the assembly cavity; a top of the assembly cavity is provided with an avoiding hole, and the top rod part passes through the avoiding hole and abuts against the pressure relief valve.

[0014] In this way, the push mechanism is not exposed, so that the push mechanism can be protected, and the appearance of the pot cover is ensured to be regular.

[0015] In one of the embodiments, the pressure relief valve comprises a valve rod, a sealing piece and a valve cap, the valve cap is arranged at a top of the valve rod and overlaps an upper edge of the exhaust cavity, and the sealing piece is arranged on the valve rod and overlaps a peripheral edge of the exhaust hole; the top rod part is located away from the handle.

[0016] In this way, the pressure relief valve has a simple structure, is convenient to produce and process, and can ensure the sealing effect of the exhaust hole; when the top rod part is turned upward and the valve cap is lifted upward, the discharged gas flows along a bottom wall of the valve cap toward a side close to the top rod part, and does not flow toward a side close to the handle, so that the user can be prevented from being scalded by the high-temperature gas when holding the handle.

[0017] In one of the embodiments, a top wall of the assembly cavity has a groove, and the valve cap is located in the groove.

[0018] In this way, the groove can limit the valve cap, so that the sealing piece can accurately overlap the peripheral edge of the exhaust hole in the closed state, and the sealing effect of the sealing piece on the exhaust hole is ensured.

[0019] In one of the embodiments, the pressure relief valve further comprises an anti-falling piece, the valve rod passes through the exhaust hole, and the anti-falling piece is arranged at a bottom of the valve rod.

[0020] In this way, the anti-falling piece can prevent the pressure relief valve from completely falling out of the exhaust hole and the exhaust cavity when the pot cover is inverted, and the parts are prevented from being lost.

[0021] In one of the embodiments, the anti-falling piece is detachably arranged on the valve rod.

[0022] In this way, the user can detach the anti-falling piece to clean the pressure relief valve and the exhaust cavity.

[0023] In one of the embodiments, the handle is provided with an opening arranged along the length direction of the handle, the opening being communicated with the assembly cavity; the force applying assembly comprises a push button and a push rod, the push button being fixed to the push rod and movably arranged in the opening, the end of the push rod away from the push button being in abutment with the force receiving part; the first limiting part and the second limiting part are both arranged on the side wall of the opening, and the matching part is arranged on the side of the push button.

[0024] In this way, when the user holds the handle, the push button can be pushed by the thumb to slide along the length direction of the handle relative to the handle, which is simple and convenient to operate; and the matching part and the limiting part are close to the position where the user applies force, which is more labor-saving to operate.

[0025] In one of the embodiments, the force receiving part has a first inclined surface, and the end of the push rod away from the push button is provided with a second inclined surface matched with the first inclined surface.

[0026] In this way, the sliding of the push rod along the length direction of the handle is converted into the rotation of the top piece around the first axis through the matching of the first inclined surface and the second inclined surface, which is simple in structure and more labor-saving to operate.

[0027] In one of the embodiments, a sealing ring is arranged between the bottom wall of the exhaust cavity and the outer wall surface of the cover.

[0028] In this way, the sealing ring can improve the sealing property between the bottom wall of the exhaust cavity and the cover, so as to prevent the gas in the pot body from overflowing through the exhaust hole and the gap between the bottom wall of the exhaust cavity and the cover to affect the cooking effect.

[0029] The utility model also provides a cooking utensil which comprises the pot cover.

The terminology used in the description herein is for describing particular embodiments only and is not intended to be limiting of the application. As used in this description, the singular forms "a", "an", and "the" include plural references unless the context clearly dictates otherwise.

[0042] Some existing cooking utensils, the pot cover will be generally provided with a vent hole, to achieve the cooking utensils inside and outside air pressure balance. This only provided with a vent hole pot cover, because it can not keep a certain air pressure in the cooking utensils, not convenient for fast cooking. In order to achieve the purpose of fast cooking, there are micro pressure pot cover on the market, the micro pressure valve on the micro pressure pot cover is controlled by holding the pot cover handle, the user needs to continuously exert force to make the micro pressure valve remain in the normal open state during the control process, the operation is not convenient.

[0043] In order to solve the above problems, as shown in Figures 1 to 7 The utility model provides a pot cover, in order to facilitate the user control micro pressure valve.

[0044] As shown in Figures 1 to 3 Specifically, the pot cover includes cover body 10, handle 20, pressure relief valve 30 and push mechanism 40, wherein: cover body 10 is provided with exhaust hole 11;Handle 20 is installed on cover body 10, handle 20 includes seat body 21 and handle 22 provided on seat body 21, seat body 21 has exhaust cavity 211 communicated with exhaust hole 11, handle 20 is provided with limiting portion 23, limiting portion 23 includes first limiting portion 231 and second limiting portion 232;Pressure relief valve 30 is arranged in exhaust cavity 211 in a lifting manner, for controlling the opening and closing of exhaust hole 11;Push mechanism 40 is movably arranged on handle 20 and is drivingly connected with pressure relief valve 30 for driving pressure relief valve 30 to lift, push mechanism 40 is provided with matching portion 411, when push mechanism 40 moves to matching portion 411 and first limiting portion 231 cooperates, then pressure relief valve 30 is in the state of lifting, when push mechanism 40 moves to matching portion 411 and second limiting portion 232 cooperates, then pressure relief valve 30 is in the state of lifting.

[0045] In the pot cover, the pot cover can be arranged on the pot body, and the user can take or place the cover body 10 through the handle 22 of the handle 20. During the cooking process, the user can control the movement of the pushing mechanism 40 relative to the handle 20, change the state of the pressure relief valve 30 in the exhaust cavity 211, and when the pushing mechanism 40 moves to the position where the cooperation part 411 cooperates with the second limiting part 232, the pressure relief valve 30 is in a liftable state, that is, the pressure relief valve 30 can be freely lifted in the exhaust cavity 211 according to the pressure in the pot, and when the gas pressure in the pot is lower than the gravity of the pressure relief valve 30, the pressure relief valve 30 is lowered to close the exhaust hole, and the gas in the pot body cannot be discharged through the exhaust hole 11, so that the gas pressure in the pot body can be increased, and when the gas pressure in the pot is greater than the gravity of the pressure relief valve 30, the pressure relief valve 30 is lifted by the gas pressure, and the gas can be discharged by the pressure relief valve 30, so that the pot can be maintained in a state of micro-pressure, and rapid cooking is realized. When the pushing mechanism 40 moves to the position where the cooperation part 411 cooperates with the first limiting part 231, the pressure relief valve 30 rises to an open state in the exhaust cavity 211 to open the exhaust hole 11, and the gas in the pot body can be discharged through the exhaust hole 11 and the exhaust cavity 211 in turn, so that the gas pressure in the pot body can be reduced, and cooking in a normal pressure working state can be realized. Moreover, by cooperating the cooperation part 411 with the first limiting part 231 or the second limiting part 232, the pushing mechanism 40 can be stably arranged at the current position without external force, so that the pressure relief valve 30 can be stably arranged in the lifted state or the liftable state, the user does not need to continuously hold the pushing mechanism 40, the user operation is facilitated, and the user can also be prevented from being scalded by the high-temperature gas discharged from the exhaust hole 11.

[0046] As shown in Figure 3 In an embodiment, the cooperation part 411 is a deformable protrusion, and the limiting part 23 is a limiting groove. The first limiting part 231 is a first limiting groove, and the second limiting part 232 is a second limiting groove. When the cooperation part 411 cooperates with the first limiting part 231, the protrusion is clamped into the first limiting groove, and when the cooperation part 411 cooperates with the second limiting part 232, the protrusion is clamped into the second limiting groove. The protrusion can be made of a material with elasticity such as silica gel or rubber. When the user applies external force to the pushing mechanism 40, the protrusion can be deformed and separated from the first limiting groove or the second limiting groove. After the protrusion is clamped into the first limiting groove or the second limiting groove, the protrusion can be reset to ensure the stability and reliability of the cooperation part 411 and the limiting part 23 in the cooperation state. Moreover, the structure of the cooperation part 411 and the limiting part 23 is simple, and the production and processing are facilitated. Specifically, two recessed grooves arranged at intervals can be formed on the wall of the handle 20 as the first limiting groove and the second limiting groove. Alternatively, a protruding structure 233 can be arranged on the wall of the handle 20, and the two sides of the protruding structure 233 cooperate with the wall of the handle 20 to form the first limiting groove and the second limiting groove.

[0047] Of course, in other embodiments, the limiting part 23 can be a deformable protrusion, and the mating part 411 can be a limiting groove, with the protrusion engaging with the limiting groove. Specifically, the first limiting part 231 is a first protrusion, and the second limiting part 232 is a second protrusion. When the mating part 411 engages with the first limiting part 231, the first protrusion engages in the limiting groove; when the mating part 411 engages with the second limiting part 232, the second protrusion engages in the limiting groove.

[0048] like Figures 5 to 6 As shown, the pushing mechanism 40 includes a force-applying component 41 and a top member 42. The force-applying component 41 is provided with a mating part 411. The top member 42 is rotatably arranged around a first axis. The top member 42 includes a top rod part 421 and a force-receiving part 422 located on both sides of the first axis. The top rod part 421 is driven to be connected to the pressure relief valve 30, and the force-receiving part 422 abuts against the force-applying component 41. When the force-applying component 41 moves relative to the handle 20, it can drive the force-receiving part 422 to rotate around the first axis, thereby driving the top member 42 as a whole to rotate around the first axis, so that the top rod part 421 also rotates around the first axis. Since the top rod part 421 and the force-receiving part 422 are located on both sides of the first axis, when the force-receiving part 422 rotates downward, the top rod part 421 will rotate upward, and conversely, when the force-receiving part 422 rotates upward, the top rod part 421 will rotate downward. When the push rod 421 flips upward, it can drive the pressure relief valve 30 to rise in the exhaust chamber 211 to open the exhaust port 11; when the push rod 421 flips downward, the pressure relief valve 30 can descend in the exhaust chamber 211 to close the exhaust port 11. The push mechanism 40 has a simple structure, which facilitates production and processing.

[0049] like Figures 5 to 6 As shown, in one embodiment, the pushing mechanism 40 further includes a fixed seat 43, which is fixed to the outer wall of the exhaust chamber 211. The fixed seat 43 is provided with a rotating fitting part 431. The top member 42 further includes a rotating part 423 and an annular connecting part 424. The rotating part 423 is located on the connecting part 424, and the push rod part 421 and the force-receiving part 422 are respectively located on both sides of the rotating part 423. The rotating part 423 is rotatably connected to the rotating fitting part 431, and the axis of the rotating part 423 is the first axis. The fixed seat 43 is used to support the top member 42, so that the top member 42 can rotate around the first axis through the rotating part 423. The connecting part 424 is used to connect the push rod part 421, the force-receiving part 422 and the rotating part 423. The connecting part 424 is set as an annular structure so that the connecting part 424 can be sleeved on the outside of the exhaust chamber 211, thereby reducing the space occupied by the top member 42 and avoiding increasing the volume of the seat 21. Of course, in other embodiments, a rotating fitting part 431 can be directly provided on the outer wall of the exhaust cavity 211 so that the top member 42 can rotate relative to the exhaust cavity 211.

[0050] like Figure 7As shown, one of the rotating part 423 and the rotating matching part 431 is a rotating shaft, and the other is a shaft hole matched with the rotating shaft. The axis of the rotating shaft and the shaft hole is the first axis. The rotation of the top piece 42 relative to the fixed seat 43 is realized by the matching of the rotating shaft and the shaft hole, which is simple in structure and can ensure the stability and reliability of the rotation of the top piece 42 relative to the fixed seat 43. When the rotating part 423 is the rotating shaft and the rotating matching part 431 is the shaft hole matched with the rotating shaft, the shaft hole can be a complete circular hole, or a semicircular hole as shown, and the rotating shaft is lapped on the semicircular hole. In addition, the number of the rotating matching part 431 is two, and the two rotating matching parts 431 are oppositely arranged on both sides of the exhaust cavity 211. The number of the rotating part 423 is two, and the two rotating parts 423 are arranged one by one corresponding to the rotating matching part 431, so as to ensure the stability and reliability of the rotation of the top piece 42 relative to the fixed seat 43.

[0051] As shown, Figures 4 to 5 The handle 20 also has an assembly cavity 212, which is located outside the exhaust cavity 211, and the push mechanism 40 is arranged in the assembly cavity 212. The top of the assembly cavity 212 is provided with an avoiding hole 213, and the top rod part 421 passes through the avoiding hole 213 and abuts against the pressure relief valve 30. The push mechanism 40 is arranged in the assembly cavity 212, so that the push mechanism 40 is not exposed, thereby protecting the push mechanism 40 and ensuring the regular appearance of the pot cover.

[0052] As shown, Figure 5 Since the condensate, oil stains or food residues and other impurities generated during cooking and the water used to clean the pot cover may enter the assembly cavity 212 through the avoiding hole 213, the bottom wall of the assembly cavity 212 and the cover body 10 are provided with a drain hole 215 communicating with the assembly cavity 212. The water or impurities entering the assembly cavity 212 through the avoiding hole 213 can be discharged through the drain hole 215, so as to avoid the accumulation of water or impurities in the assembly cavity 212 and make it difficult to clean, thereby facilitating the user to clean the handle 20 and the pressure relief valve 30.

[0053] As shown, Figures 5 to 6As shown, the exhaust cavity 211 is in a cylindrical shape, and the pressure relief valve 30 comprises a valve rod 31, a sealing member 32 and a valve cap 33. The valve cap 33 is arranged on the top of the valve rod 31 and overlaps the upper edge of the exhaust cavity 211, and the sealing member 32 is arranged on the valve rod 31 and overlaps the circumferential edge of the exhaust hole 11. In an embodiment, the top rod part 421 and the valve cap 33 are in a split structure, and the top rod part 421 penetrates the avoiding hole 213 and abuts against the valve cap 33. When the top rod part 421 is flipped upward, the valve cap 33 is lifted upward, so that the pressure relief valve 30 is lifted to an open state, the valve cap 33 is separated from the upper edge of the exhaust cavity 211, and the sealing member 32 is separated from the circumferential edge of the exhaust hole 11, so that the gas in the pot body can be discharged through the exhaust hole 11 and the exhaust cavity 211. When the top rod part 421 is flipped downward, the pressure relief valve 30 can be lowered to close the exhaust hole 11 under the action of gravity, the valve cap 33 overlaps the upper edge of the exhaust cavity 211, and the sealing member 32 overlaps the circumferential edge of the exhaust hole 11, so as to seal the exhaust hole 11 and the exhaust cavity 211, preventing the gas in the pot body from being discharged through the exhaust hole 11 and the exhaust cavity 211. The structure of the pressure relief valve 30 is simple, easy to produce and process, and can ensure the sealing effect of the exhaust hole 11. Moreover, when the gas pressure in the pot body is greater than the gravity of the pressure relief valve 30, the gas can push away the pressure relief valve 30 to be discharged, so that the gas in the pot body can be discharged through the exhaust hole 11 and the exhaust cavity 211 in time, and when the gas pressure in the pot body decreases, the pressure relief valve 30 can be lowered to close the exhaust hole 11 under the action of gravity, achieving the effect of fast cooking under a micro-pressure state. In another embodiment, the top rod part 421 can be directly connected with the valve cap 33 or the valve rod 31, and when the top rod part 421 is flipped upward, the pressure relief valve 30 is lifted to an open state, and when the top rod part 421 is flipped downward, the pressure relief valve 30 is lowered to a closed state. The sealing member 32 can be made of silica gel, rubber or other elastic materials, so that the pressure relief valve 30 is more easily lifted when the gas pressure in the pot body is high. The valve rod 31 and the valve cap 33 can be made of the same material as the sealing member 32, or other hard materials, so that the pressure relief valve 30 is more stable and reliable.

[0054] Moreover, the top rod part 421 is located away from the handle 22. When the top rod part 421 is flipped upward and lifts the valve cap 33 upward, since the outer diameter of the valve rod 31 is smaller than the inner diameter of the exhaust cavity 211, and the valve cap 33 is separated from the upper edge of the exhaust cavity 211 and the sealing member 32 is separated from the circumferential edge of the exhaust hole 11, the pressure relief valve 30 will be inclined, so that the side of the valve cap 33 close to the top rod part 421 is higher than the side of the valve cap 33 close to the handle 22. After the gas in the pot body is discharged through the exhaust hole 11 and the exhaust cavity 211, it will flow along the bottom wall of the valve cap 33 towards the side close to the top rod part 421, but not towards the side close to the handle 22, so as to prevent the user from being scalded by the high-temperature gas when holding the handle 22.

[0055] As shown in FIG. 6, the top rod part 421 is connected with the valve cap 33 through a connecting rod 431, and the connecting rod 431 is connected with the valve cap 33 through a connecting hole 432 arranged on the valve cap 33. The connecting rod 431 is connected with the top rod part 421 through a connecting hole 433 arranged on the top rod part 421. When the top rod part 421 is flipped upward, the connecting rod 431 is lifted to an open state, and when the top rod part 421 is flipped downward, the connecting rod 431 is lowered to a closed state. Figure 5As shown, the top wall of the assembly cavity 212 has a groove 214, and the valve cap 33 is located in the groove 214. The groove 214 can limit the valve cap 33, so that the sealing element 32 can accurately overlap the periphery of the exhaust hole 11 in the liftable state, thereby ensuring the sealing effect of the sealing element 32 on the exhaust hole 11.

[0056] As shown in FIG. 1, the pressure relief valve 30 is detachably arranged in the exhaust cavity 211. In this way, it is convenient for the user to disassemble and clean the pressure relief valve 30 and the exhaust cavity 211, and the pressure relief valve 30 can be replaced alone when it is damaged, which is low in cost. The inner wall of the exhaust cavity 211 can be a smooth inner wall to prevent impurities such as oil stains or food residues from accumulating in the exhaust cavity 211, making it more convenient for the user to clean. Figure 2 Figure 5 As shown in FIG. 1, the pressure relief valve 30 is detachably arranged in the exhaust cavity 211. In this way, it is convenient for the user to disassemble and clean the pressure relief valve 30 and the exhaust cavity 211, and the pressure relief valve 30 can be replaced alone when it is damaged, which is low in cost.
