The terminology used in the description of the present application herein is for the purpose of describing particular embodiments only and is not intended to be limiting of the present application. As used herein, the singular forms "a", "an" and "the" are intended to include the plural forms as well, unless the context clearly indicates otherwise.

[0035] Some existing cooking utensils have air holes on the pot cover to balance the air pressure inside and outside the cooking utensil. The pot cover with only air holes cannot maintain a certain air pressure inside the cooking utensil, which is not convenient for fast cooking. In order to achieve fast cooking, there are micro-pressure pot covers on the market, which have a micro-pressure valve that can be lifted on the cover, and the micro-pressure valve is lifted and lowered to realize the conversion between normal pressure and micro-pressure in the pot body, thereby realizing two cooking modes of general cooking and fast cooking. Since the conversion mechanism needs to be set in the micro-pressure valve, after being used for a period of time, the micro-pressure valve will inevitably have a lot of oil stains or food residues, but the internal cleaning of the micro-pressure valve on the existing pot cover is not convenient.

[0036] To solve the above problems, as shown in Figures 1 to 7 The present application first provides a pot cover to facilitate the internal cleaning of the micro-pressure valve.

[0037] As shown in Figure 1 and Figure 5As shown, specifically, the pot cover comprises a cover body 10, a seat body 21, a pressure relief valve 30 and a pushing mechanism 40, wherein: the cover body 10 is provided with an exhaust hole 11; the seat body 21 has an exhaust cavity 211 and an assembly cavity 212 located outside the exhaust cavity 211, and the top of the assembly cavity 212 is provided with an avoiding hole 213; the pressure relief valve 30 is movably arranged in the exhaust cavity 211 for controlling the opening and closing of the exhaust hole 11; the pushing mechanism 40 is arranged in the assembly cavity 212, and the pushing mechanism 40 comprises a top rod part 421, which is movably arranged in the avoiding hole 213 and abuts against the pressure relief valve 30 to drive the pressure relief valve 30 to move; and the bottom wall of the assembly cavity 212 and the cover body 10 are provided with a water drain hole 215 which is in communication with the assembly cavity 212.

[0038] In the pot cover, the pot cover can be arranged on the pot body, in the cooking process, the user can control the top rod part 421 of the pushing mechanism 40 to ascend and descend in the avoiding hole 213 to drive the pressure relief valve 30 to move in the exhaust cavity 211, when the top rod part 421 descends, the pressure relief valve 30 can freely ascend and descend in the exhaust cavity 211 according to the pressure in the pot body, when the gas pressure in the pot body is lower than the gravity of the pressure relief valve 30, the pressure relief valve 30 descends to close the exhaust hole 11, 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, 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 pot body is maintained in a state of micro-pressure, and rapid cooking is realized; when the top rod part 421 ascends, the pressure relief valve 30 can be kept in the state of ascending in the exhaust cavity 211, 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 the normal pressure working state is realized. The condensate water, oil stains or food residues and other impurities generated in the cooking process and the water for cleaning the pot cover can enter the assembly cavity 212 through the avoiding hole 213, and then be discharged through the water drain hole 215, so that the water or impurities are prevented from accumulating in the assembly cavity 212 and being difficult to clean, and the user can clean the seat body 21 and the pressure relief valve 30 conveniently. Moreover, the pushing mechanism 40 is arranged in the assembly cavity 212, so that the pushing mechanism 40 is not exposed, and the pushing mechanism 40 can be protected, and the appearance of the pot cover is regular.

[0039] As shown in the drawings, Figures 5 to 6As shown, the pushing mechanism 40 comprises a force applying assembly 41 and a top piece 42, the force applying assembly 41 is provided with a matching part 411, and the top piece 42 is rotatably arranged around the first axis, the top piece 42 comprises 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 connected with the pressure relief valve 30, and the force receiving part 422 abuts against the force applying assembly 41. When the force applying assembly 41 moves relative to the handle 22, the force receiving part 422 can be driven to overturn around the first axis, thereby driving the top piece 42 to rotate as a whole around the first axis, so that the top rod part 421 also overturns around the first axis, and because the top rod part 421 and the force receiving part 422 are respectively located on both sides of the first axis, when the force receiving part 422 overturns downward, the top rod part 421 will overturn upward, and conversely, when the force receiving part 422 overturns upward, the top rod part 421 will overturn downward. When the top rod part 421 overturns upward, the pressure relief valve 30 can be lifted in the exhaust cavity 211 to open the exhaust hole 11; when the top rod part 421 overturns downward, the pressure relief valve 30 can be lowered in the exhaust cavity 211 to close the exhaust hole 11. The pushing mechanism 40 has a simple structure, so as to facilitate production and processing.

[0040] As Figures 5 to 6 shown, in an embodiment, the pushing mechanism 40 further comprises a fixing seat 43, the fixing seat 43 is fixedly arranged on the outer wall of the exhaust cavity 211, and the fixing seat 43 is provided with a rotating matching part 431; the top piece 42 further comprises a rotating part 423 and an annular connecting part 424, the rotating part 423 is arranged on the connecting part 424, and the top 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 with the rotating matching part 431, and the axis of the rotating part 423 is the first axis. The fixing seat 43 is used for supporting the top piece 42, so that the top piece 42 can rotate around the first axis through the rotating part 423, and the connecting part 424 is used for connecting the top rod part 421, the force receiving part 422 and the rotating part 423, and the connecting part 424 is arranged in an annular structure, so that the connecting part 424 can be sleeved on the exhaust cavity 211, thereby reducing the space occupied by the top piece 42 and avoiding increasing the volume of the seat body 21. Of course, in other embodiments, the rotating matching part 431 can be directly arranged on the outer wall of the exhaust cavity 211, so that the top piece 42 can rotate relative to the exhaust cavity 211.

[0041] As 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 has a simple 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 rotating matching parts 431 is two, and the two rotating matching parts 431 are oppositely arranged on both sides of the exhaust cavity 211. The number of rotating parts 423 is two, and they are arranged one by one with the rotating matching parts 431, so as to ensure the stability and reliability of the rotation of the top piece 42 relative to the fixed seat 43.

[0042] As 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 a closed state 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, thereby preventing the gas in the pot body from being discharged through the exhaust hole 11 and the exhaust cavity 211. The pressure relief valve 30 has a simple structure, is 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 in time through the exhaust hole 11 and the exhaust cavity 211, and when the gas pressure in the pot body decreases, the pressure relief valve 30 can be lowered to a closed state under the action of gravity, thereby preventing the gas pressure in the pot body from being too large to cause danger and improving the use safety. 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 large. 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.

[0043] 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, the gas will flow along the bottom wall of the valve cap 33 toward the side close to the top rod part 421, and will not flow toward the side close to the handle 22, thereby preventing the user from being scalded by the high-temperature gas when holding the handle 22.

[0044] AsFigure 5 As 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 closed state of the pressure relief valve 30, thereby ensuring the sealing effect of the sealing element 32 on the exhaust hole 11.

[0045] As shown in Figure 2 and Figure 5 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 also 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.

[0046] As shown in Figures 5 to 6 The pressure relief valve 30 further comprises a anti-dropping element 34, the valve rod 31 passes through the exhaust hole 11 at the bottom, and the anti-dropping element 34 is arranged at the bottom of the valve rod 31. The anti-dropping element 34 can prevent the pressure relief valve 30 from completely coming out of the exhaust hole 11 and the exhaust cavity 211 when the pot cover is inverted, thereby preventing the loss of parts. Further, the anti-dropping element 34 is detachably arranged on the valve rod 31. After the anti-dropping element 34 is detached, the pressure relief valve 30 can come out of the exhaust hole 11 and the exhaust cavity 211 towards the side close to the valve cap 33, so as to realize the detachable arrangement of the pressure relief valve 30.

[0047] As shown in Figures 2 to 4 In an embodiment, the handle 22 is provided with a movable opening opening 221 arranged along the length direction of the handle 22, and the movable opening opening 221 is in communication with the assembly cavity 212; the force applying assembly 41 comprises a push button 412 and a push rod 413, the push button 412 is fixedly arranged on the push rod 413 and movably arranged in the movable opening opening 221, and the end of the push rod 413 away from the push button 412 is in abutment with the stress receiving portion 422. In this way, when the user holds the handle 22, the push button 412 can be pushed by the thumb to slide along the length direction of the handle 22 relative to the handle 22, thereby driving the push rod 413 to slide along the length direction of the handle 22, and the push rod 413 can drive the stress receiving portion 422 to flip around the first axis, which is simple and convenient to operate.

[0048] As shown in Figures 1 to 3As shown, the handle 22 is provided with a limiting portion 23, which includes a first limiting portion 231 and a second limiting portion 232; the push mechanism 40 is provided with a cooperating portion 411, when the push mechanism 40 moves to the position where the cooperating portion 411 cooperates with the first limiting portion 231, the exhaust hole 11 is in an open state, and when the push mechanism 40 moves to the position where the cooperating portion 411 cooperates with the second limiting portion 232, the exhaust hole 11 is in a closed state. When the push mechanism 40 moves to the position where the cooperating portion 411 cooperates with the second limiting portion 232, the pressure relief valve 30 descends in the exhaust cavity 211 to the closed state to close the exhaust hole 11; when the push mechanism 40 moves to the position where the cooperating portion 411 cooperates with the first limiting portion 231, the pressure relief valve 30 rises in the exhaust cavity 211 to the open state to open the exhaust hole 11. By cooperating the cooperating portion 411 with the first limiting portion 231 or the second limiting portion 232, the push mechanism 40 can be stably positioned at the current position without external force, so that the pressure relief valve 30 can be stably positioned at the closed state or the open state, without the user continuously holding the push mechanism 40, which is convenient for the user to operate, and can also prevent the user from being scalded by the high-temperature gas discharged from the exhaust hole 11.

[0049] Specifically, the first limiting portion 231 and the second limiting portion 232 are arranged on the side wall of the opening 221, the cooperating portion 411 is arranged on the push button 412, and the cooperating portion 411 can cooperate with the first limiting portion 231 or the second limiting portion 232. Moreover, arranging the cooperating portion 411 on the push button 412 and arranging the first limiting portion 231 and the second limiting portion 232 on the side wall of the opening 221 makes the cooperating portion 411 and the limiting portion 23 close to the position where the user applies force, which is more labor-saving for operation.

[0050] As shown, Figure 3 In an embodiment, the cooperating portion 411 is a deformable protrusion, and the limiting portion 23 is a limiting groove, and the protrusion is clamped in the limiting groove. Specifically, the first limiting portion 231 is a first limiting groove, the second limiting portion 232 is a second limiting groove, when the cooperating portion 411 cooperates with the first limiting portion 231, the protrusion is clamped in the first limiting groove, and when the cooperating portion 411 cooperates with the second limiting portion 232, the protrusion is clamped in the second limiting groove. The protrusion can be made of a material with elasticity such as silica gel or rubber, and when the user applies external force to the push mechanism 40, the protrusion can deform and come out of the first limiting groove or the second limiting groove, and the protrusion can reset after being clamped in the first limiting groove or the second limiting groove, so as to ensure the stability and reliability of the cooperation between the cooperating portion 411 and the limiting portion 23 in the cooperating state, and the structure of the cooperating portion 411 and the limiting portion 23 is simple, which is convenient for production and processing. Specifically, two recessed grooves arranged at intervals can be formed on the wall of the handle 22 as the first limiting groove and the second limiting groove; or a protruding structure 233 can be arranged on the wall of the handle 22, and the two sides of the protruding structure 233 cooperate with the wall of the handle 22 to form the first limiting groove and the second limiting groove.

[0051] 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.

[0052] like Figure 2 As shown, the handle 22 includes a first shell 222 and a second shell 223 that are detachably connected. The first shell 222 and the second shell 223 surround and form a mounting cavity that communicates the assembly cavity 212 and the opening 221. The opening 221 is located in the first shell 222 or the second shell 223. The push rod 413 is located in the mounting cavity. The push button 412 extends into the mounting cavity from the opening 221 and is connected to the push rod 413, thereby facilitating the installation of the force application component 41.

[0053] Of course, in other embodiments, the mating part 411 can also be provided on the push rod 413, and the first limiting part 231 and the second limiting part 232 are both provided on the inner wall of the mounting cavity; the force application component 41 can also move along the width direction or thickness direction of the handle 22, etc. When the user holds the handle 22, he can press the push button 412 with his thumb, thereby driving the push rod 413 to slide along the width direction or thickness direction of the handle 22, and the push rod 413 can drive the force receiving part 422 to rotate around the first axis; or, the force application component 41 can also be provided in the assembly cavity 212, as long as the top part 42 can be controlled to rotate around the first axis by the force application component 41. This utility model embodiment does not make specific limitations here. Among them, the length direction of the handle 22 is the direction in which the handle 22 extends outward from the seat 21, and the width direction and thickness direction of the handle 22 are approximately perpendicular to the length direction of the handle 22.

[0054] like Figure 5 and Figure 7As shown, in an embodiment, when the force applying assembly 41 slides along the length direction of the handle 22 relative to the handle 22, the force receiving part 422 has a first inclined surface 4221, and the push rod 413 has a second inclined surface 4131 at the end away from the push button 412. At this time, along the length direction of the handle 22, the first limiting part 231 is located on the side of the second limiting part 232 close to the base body 21. When the push button 412 and the push rod 413 are pushed towards the side close to the base body 21, the second inclined surface 4131 and the first inclined surface 4221 slide to make the force receiving part 422 overturn downward, the top rod part 421 overturn upward and push the valve cover 33 upward, and the pressure relief valve 30 rises to the open state; when the push button 412 and the push rod 413 are pushed towards the side away from the base body 21, the pressure relief valve 30 can fall to the closed state under the action of gravity, and the top rod part 421 is pressed to make the top rod part 421 overturn downward, and the force receiving part 422 overturns upward to the position where the first inclined surface 4221 and the second inclined surface 4131 abut. Through the cooperation of the first inclined surface 4221 and the second inclined surface 4131, the sliding of the push rod 413 along the length direction of the handle 22 is converted into the rotation of the top piece 42 around the first axis, which is simple in structure and more labor-saving in operation.

[0055] Of course, in other embodiments, only one of the push rod 413 and the force receiving part 422 can be provided with an inclined surface; or, other cooperation modes can be adopted between the two, and in other cooperation modes, when the force applying assembly 41 is pushed towards the side close to the base body 21, the force receiving part 422 can overturn upward, the top rod part 421 can overturn downward, and the pressure relief valve 30 can fall to the closed state; when the force applying assembly 41 is pushed towards the side away from the base body 21, the force receiving part 422 can overturn downward, the top rod part 421 can overturn upward, and the pressure relief valve 30 can rise to the open state, as long as the sliding of the force applying assembly 41 along the length direction of the handle 22 relative to the handle 22 can be converted into the rotation of the top piece 42 around the first axis, which is not specifically limited in the embodiments of the present application.

[0056] As shown in FIGS. 1, 2 and 3, the top piece 42 is provided with a first axis O1, and the valve cover 33 is provided with a second axis O2.
