Specifically, the electric pressure cooker can achieve a pressure-free cooking state or a pressure cooking state through the cooperation of a pressure limiting valve and an exhaust pipe. The user can control the working state of the electric pressure cooker by operating the operating element on the electric pressure cooker according to his or her needs.

[0003] When the electric pressure cooker is in the pressure cooking state, there is a certain pressure and high-temperature steam in the pot. At this time, if the user mistakenly operates the operating part and switches the electric pressure cooker from the pressure cooking state to the pressure-free cooking state, steam will spray out from the exhaust pipe, which may cause the user to be scalded by the sprayed steam.

It should be noted that similar reference numerals and letters represent similar items in the following drawings, and therefore, once a certain item is defined in an accompanying drawing, it does not need to be further discussed in subsequent drawings.

[0034] like Figures 1 to 4 As shown, the present application provides a cover assembly, and an embodiment of the cover assembly of the present application includes: a cover body 10, an exhaust pipe 20, a pressure limiting valve 30, an operating member 40, and a stop member 50; the exhaust pipe 20 is penetrated through the cover body 10, and the exhaust pipe 20 has an exhaust channel 21; the pressure limiting valve 30 has an exhaust state and an upper pressure state, when the pressure limiting valve 30 is in the exhaust state, the pressure limiting valve 30 avoids the exhaust channel 21, and when the pressure limiting valve 30 is in the upper pressure state, the pressure limiting valve 30 blocks the exhaust channel 21; the operating member 40 can be movably arranged on the cover body 10 and can drive the pressure limiting valve 30 to switch between the exhaust state and the upper pressure state; the stop member 50 is penetrated through the cover body 10 so as to be movable up and down, when the pressure limiting valve 30 is in the upper pressure state, the stop member 50 can be in an ascending position and cooperate with the operating member 40 to limit the position, so that the position of the operating member 40 relative to the cover body 10 remains unchanged.

[0035] By applying the technical solution of this embodiment, the cover body 10 provides an installation basis for various components and can maintain the sealing of the cooking cavity. The exhaust pipe 20 is penetrated by the cover body 10 and is provided with an exhaust channel 21 connecting the cooking cavity and the external space. The steam in the cooking cavity can be discharged to the external space through the exhaust channel 21. The pressure limiting valve 30 has an exhaust state and an upper pressure state. When the pressure limiting valve 30 is in the upper pressure state, the pressure limiting valve 30 blocks the exhaust channel 21, and the pressure in the cooking cavity continues to increase to achieve pressure cooking of the food in the cooking cavity; when the pressure limiting valve 30 is in the exhaust state, the pressure limiting valve 30 avoids the exhaust channel 21, and the cooking cavity is connected with the external space to achieve pressure-free cooking of the food in the cooking cavity; the cover body assembly also includes an operating member 40, and the user can operate The operating member 40 drives the pressure limiting valve 30 to switch between the exhaust state and the pressure state; when the pressure limiting valve 30 is in the pressure state, the pressure in the cooking cavity gradually increases. When the pressure in the cooking cavity reaches the preset value, the stopper 50 moves upward under the pressure in the cooking cavity, and the stopper 50 moves from the lowered position to the raised position and remains in the raised position. The stopper 50 cooperates with the operating member 40 to limit the position, so that the position of the operating member 40 relative to the cover body 10 remains unchanged, and the user cannot operate the operating member 40, thereby avoiding the user's misoperation during cooking that causes the pressure limiting valve to be in an incorrect state, that is, avoiding the user's misoperation of the operating member 40 that causes the pressure limiting valve 30 to switch from a pressure state to a pressure-free state and being scalded by the ejected steam. Therefore, the technical solution of this embodiment can effectively solve the problem in the related art that there is a certain probability that the user misoperates during cooking that causes the pressure limiting valve to be in an incorrect state.

[0036] It should be noted that, in the present embodiment, the operating member 40 is a rotating operating member, and the operating member 40 is rotatably disposed on the cover body 10. In addition, in other embodiments not shown in the figure, the operating member can also move horizontally or vertically relative to the cover body, as long as the operating member can drive the pressure limiting valve to switch between the exhaust state and the upper pressure state through movement. It should be noted that "when the pressure limiting valve 30 is in the upper pressure state, the stop member 50 can be in the rising position" means that when the pressure limiting valve 30 switches from the exhaust state to the upper pressure state and remains in the upper pressure state, the pressure in the cooking chamber gradually increases until the pressure rises to a preset value, and the stop member 50 will be lifted up by the steam pressure and be in the rising position.

[0037] like Figures 1 to 4As shown, the operating member 40 includes an operating button 41 movably arranged on the cover 10 and a clamping plate 42 connected to the operating button 41, and a first clamping hole 421 is arranged on the clamping plate 42. When the pressure limiting valve 30 is in the upward pressure state, the stopper 50 is inserted and limited in the first clamping hole 421. Specifically, in this embodiment, the operating button 41 is an operating knob, and the rotation of the operating button 41 will drive the clamping plate 42 to rotate along the circumferential direction of the operating button 41. When the operating button 41 rotates to the first preset position, the operating member 40 can switch the pressure limiting valve 30 to the upward pressure state. At this time, the first clamping hole 421 on the clamping plate 42 also moves to a position corresponding to the stopper 50. When the pressure in the cooking cavity reaches a preset value, the stopper 50 switches from the descending position to the ascending position and remains in the ascending position. At this time, the stopper 50 is inserted in the first clamping hole 421 and cooperates with the first clamping hole 421 to limit the rotation of the operating member 40 relative to the cover 10, thereby avoiding user misoperation. In addition, when the pressure in the cooking chamber gradually decreases and is lower than the preset value, the stop member 50 switches from the raised position to the lowered position. At this time, the stop member 50 and the first clamping hole 421 are disengaged from the limiting cooperation, so that the operating member 40 can rotate relative to the cover body 10, so that the user can switch the pressure limiting valve 30 to the exhaust state.

[0038] In this embodiment, no matter the stopper 50 is in the ascending position or the descending position, it is inserted in the card plate 42, and the stopper 50 is never separated from the card plate 42; when the stopper 50 is in the descending position, the stopper 50 and the first card hole 421 are no longer limited in position, so that the operating member 40 can rotate. In other embodiments not shown in the figure, when the stopper is switched from the ascending position to the descending position, the stopper can be completely separated from the card plate, so that the stopper and the first card hole are out of limited position.

[0039] like Figures 1 to 4As shown, the stop member 50 includes a first stop rod 51 and a second stop rod 52 connected to the bottom of the first stop rod 51, the outer diameter of the second stop rod 52 is larger than the outer diameter of the first stop rod 51, and the clamping plate 42 is also provided with an avoidance hole 422 and a first connecting groove 423 connecting the avoidance hole 422 and the first clamping hole 421, the width of the avoidance hole 422 and the width of the first connecting groove 423 are larger than or equal to the outer diameter of the first stop rod 51, the width of the first connecting groove 423 is smaller than the outer diameter of the second stop rod 52, and when the pressure limiting valve 30 is in the exhaust state, the stop member 50 is in the lowered position, and the first stop rod 51 is located in the avoidance hole 422. Specifically, when the pressure-limiting valve 30 is in the upward pressure state, the stop member 50 can move upward and switch to the raised position. At this time, the first stop rod 51 is located above the first clamping hole 421, and the first clamping hole 421 corresponds to the second stop rod 52. Since the width of the first connecting groove 423 is smaller than the outer diameter of the second stop rod 52, the second stop rod 52 cannot cross the first connecting groove 423, so that the stop member 50 is limited in the first clamping hole 421, thereby keeping the pressure-limiting valve 30 in the upward pressure state, and the user cannot switch the state of the pressure-limiting valve 30 by rotating the operating member 40; when the pressure in the cooking chamber gradually decreases and is lower than the preset value 423, the first stop rod 51 corresponds to the first stop rod 51. Since the width of the avoidance hole 422 and the width of the first connecting groove 423 are greater than or equal to the outer diameter of the first stop rod 51, the first stop rod 51 can be moved into the first connecting groove 423 and the avoidance hole 422, so that the user can switch from the correspondence between the first card hole 421 and the stop member 50 to the correspondence between the avoidance hole 422 and the stop member 50 by turning the operating button 41, that is, the pressure limiting valve 30 can be switched from the upper pressure state to the exhaust state. In this embodiment, no matter the stop member 50 is in the raised position or the lowered position, the stop member 50 is always inserted in the through groove formed by the first clamping hole 421, the first connecting groove 423 and the avoidance hole 422, thereby ensuring that the stop member 50 and the through groove are always in a aligned state, and the stop member 50 and the through groove will not be misaligned due to the rotation of the clamping plate 42.

[0040] like Figures 1 to 4As shown, the first connecting groove 423 includes a main groove section 4231, a first flared section 4232 and a second flared section 4233. The first flared section 4232 is located between the main groove section 4231 and the avoidance hole 422. In the direction toward the avoidance hole 422, the width of the first flared section 4232 increases. The second flared section 4233 is located between the main groove section 4231 and the first clamping hole 421. In the direction toward the first clamping hole 421, the width of the second flared section 4233 increases. Specifically, when the clamping plate 42 rotates to drive the through groove to move so that the stopper 50 slides in the through groove, the first flared section 4232 and the second flared section 4233 can guide the stopper 50, so that the stopper 50 can smoothly slide from the avoidance hole 422 to the first clamping hole 421 or from the first clamping hole 421 to the avoidance hole 422, thereby reducing the possibility of the stopper 50 getting stuck during the sliding process.

[0041] It should be noted that, in this embodiment, "the width of the first connecting groove 423 is greater than or equal to the outer diameter of the first stop rod 51" means that the width of the main groove section 4231 is greater than or equal to the outer diameter of the first stop rod 51, that is, the minimum width of the first connecting groove 423 is greater than or equal to the outer diameter of the first stop rod 51; "the width of the first connecting groove 423 is smaller than the outer diameter of the second stop rod 52" means that the width of the first expansion section 4232 close to the avoidance hole 422 and the width of the second expansion section 4233 close to the first clamping hole 421 are smaller than the outer diameter of the second stop rod 52, that is, the maximum width of the first connecting groove 423 is smaller than the outer diameter of the second stop rod 52.

[0042] like Figures 1 to 4 As shown, the operating member 40 further includes a connecting rod 43 disposed between the operating button 41 and the clamping plate 42, the connecting rod 43 extending in the vertical direction, and the clamping plate 42 detachably connected to the lower end of the connecting rod 43. Specifically, the upper end of the connecting rod 43 is fixedly connected to the operating button 41, the clamping plate 42 is detachably connected to the lower end of the connecting rod 43, and the clamping plate 42 and the connecting rod 43 form a split structure, making the processing of the clamping plate 42 easier. In addition, the clamping plate 42 and the connecting rod 43 are connected by screws that penetrate the clamping plate 42 and the connecting rod 43 from bottom to top.

[0043] like Figures 1 to 4 As shown, a stop cylinder 424 is provided on the card plate 42, and the lower end of the connecting rod 43 is inserted into the stop cylinder 424. Specifically, the stop cylinder 424 is a cylindrical structure provided on the upper surface of the card plate 42, and the lower end of the connecting rod 43 is inserted into the stop cylinder 424 from top to bottom. The connecting rod 43 and the stop cylinder 424 are anti-rotationally matched, thereby ensuring that when the operating button 41 is rotated, the card plate 42 can be driven to rotate along the circumferential direction of the operating button 41 through the connecting rod 43.

[0044] In addition, in the present embodiment, the cover assembly further includes an outer cover, a first induction member, and a second induction member. The outer cover is arranged above the cover body 10, the first induction member is arranged on the operating member 40 and can move synchronously with the operating member 40, and the second induction member is arranged on the outer cover and can cooperate with the first induction member in induction. Specifically, when the operating member 40 rotates to drive the pressure limiting valve 30 to switch between the exhaust state and the upper pressure state, the first induction member will also rotate with the operating member 40 and move synchronously and change position with the second induction member, so that the induction signal of the second induction member changes, thereby realizing the detection of the working state of the pressure limiting valve 30. In the present embodiment, the first induction member is a magnet, and the second induction member is a reed switch or a Hall switch.

[0045] like Figure 3 , Figure 4 As shown, the cover assembly also includes a stop plate 60, which is movably arranged on the cover 10. When the pressure-limiting valve 30 is in an upward pressure state, the stop member 50 cooperates with the stop plate 60 to limit the rotation of the cover 10. Specifically, the stop plate 60 has a first hole 61 and a second hole 62 arranged along the radial direction of the cover 10. The first hole 61 and the second hole 62 are connected and arranged, and the first hole 61 is located on the inner side of the second hole 62. The width of the first hole 61 is smaller than the width of the second hole 62. The stop member 50 also includes a third stop rod 53 arranged above the first stop rod 51. When the pressure-limiting valve 30 is in an upward pressure state and the stop member 50 is in an ascending position, the first stop rod 51 and the third stop rod 53 are both located above the second hole 62. The inner wall surface of the second hole 62 cooperates with the second stop rod 52 to limit the stop plate 60 from moving outward relative to the cover 10. When the user attempts to rotate the cover 10, the cover 10 has the function of rotating relative to the pot body. However, the teeth on the pot body cannot push the stop plate 60 outward, that is, the stop plate 60 cooperates with the teeth of the pot to stop, thereby limiting the rotation of the cover body 10; when the pressure in the cooking chamber drops below the preset value, the stop member 50 is in the lowered position, the second stop rod 52 and the first stop rod 51 are located below the second hole 62, and the third stop rod 53 corresponds to the second hole 62. At this time, the third stop rod 53 can enter the first hole 61 from the second hole 62, so that the stop plate 60 can move outward relative to the cover body 10. When the user rotates the cover body 10, the cover body 10 rotates relative to the pot body and the teeth on the pot body can push the stop plate 60 outward so that the stop plate 60 can avoid the teeth of the pot, thereby allowing the cover body 10 to rotate. In other words, the stop member 50 can simultaneously prevent the cover body 10 from rotating and the operating member 40 from rotating when the pressure in the cooking chamber is greater than the preset value, which can effectively prevent the user from being injured due to operation by mistake, and has the advantage of simple structure.

[0046] like Figures 5 to 7As shown, in the present embodiment, the pressure limiting valve 30 includes an inner valve 31 and an outer valve 32 arranged on the outer periphery of the inner valve 31, the inner valve 31 can avoid or block the exhaust passage 21, the operating member 40 can drive the outer valve 32 to move in the up and down directions, so that the outer valve 32 can press down the inner valve 31, lift the inner valve 31 or separate from the inner valve 31, the upper pressure state includes a first pressure state and a second pressure state, when the pressure limiting valve 30 is in the exhaust state, the outer valve 32 lifts the inner valve 31 so that the inner valve 31 avoids the exhaust passage 21, when the pressure limiting valve 30 is in the first pressure state, the outer valve 32 separates from the inner valve 31 so that the inner valve 31 blocks the exhaust passage 21, when the pressure limiting valve 30 is in the second pressure state, the outer valve 32 presses down the inner valve 31 so that the inner valve 31 and the outer valve 32 jointly block the exhaust passage 21.

[0047] Specifically, the operating button 41 is provided with a mounting groove 411 extending in the up-down direction, and the outer valve 32 is provided with a mounting rib 321 cooperating with the mounting groove 411. The cooperation between the mounting groove 411 and the mounting rib 321 can make the outer valve 32 and the operating button 41 stop rotating. The cover body 10 is provided with a protrusion 11, and the outer valve 32 is provided with a plurality of matching surfaces 322 of different heights relative to the cover body 10. The rotation of the operating button 41 drives the outer valve 32 to rotate, so that the matching surfaces 322 of different heights cooperate with the protrusion 11, so that the height of the outer valve 32 relative to the cover body 10 can be adjusted (that is, the outer valve 32 can move up and down relative to the cover body 10); in addition, the inner valve 31 includes a first protrusion 311 and a second protrusion 312 arranged at intervals, and the first protrusion 311 is located above the second protrusion 312. When the outer valve 32 When it moves to the position where the outer valve 32 and the lower surface of the first protrusion 311 are abutted and matched, at this time, the outer valve 32 lifts the inner valve 31 upward, and the inner valve 31 avoids the exhaust channel 21, so that the pressure limiting valve 30 is in the exhaust state, thereby realizing pressure-free cooking; when the outer valve 32 moves to the position where the outer valve 32 neither cooperates with the first protrusion 311 nor the second protrusion 312 (that is, the outer valve 32 is separated from the inner valve 31), at this time, only the inner valve 31 is pressed on the exhaust pipe 20, and the pressure limiting valve 30 is in the first pressure state, thereby realizing low-pressure cooking; when the outer valve 32 moves to the position where the outer valve 32 and the second protrusion 312 are matched, at this time, the outer valve 32 presses down the inner valve 31, which is equivalent to the inner valve 31 and the outer valve 32 being pressed on the exhaust pipe 20 together, and the pressure limiting valve 30 is in the second pressure state, thereby realizing high-pressure cooking.

[0048] It should be noted that the above-mentioned “plurality” refers to two or more. Specifically, in this embodiment, there are three mating surfaces 322 .

[0049] like Figures 1 to 4As shown, a second clamping hole 425 and a second connecting groove 426 connecting the first clamping hole 421 and the second clamping hole 425 are also provided on the clamping plate 42. The second clamping hole 425 is located on the side of the first clamping hole 421 away from the avoidance hole 422. The width of the second connecting groove 426 is greater than or equal to the outer diameter of the first stop rod 51 and smaller than the outer diameter of the second stop rod 52. When the pressure limiting valve 30 is in the first pressure state, the second stop rod 52 can cooperate with the first clamping hole 421 in a limiting position. When the pressure limiting valve 30 is in the second pressure state, the second stop rod 52 can cooperate with the second clamping hole 425 in a limiting position. Specifically, in the present embodiment, the second connecting groove 426 has the same structure as the first connecting groove 423. By setting the second clamping hole 425, when the pressure limiting valve 30 is in the second pressure state, the stop member 50 is in the ascending position, and the second stop rod 52 cooperates with the second clamping hole 425 to limit the rotation of the operating button 41 relative to the cover body 10, thereby preventing the user from accidentally operating the pressure limiting valve 30 to switch from the second pressure state to the first pressure state or to switch from the second pressure state to the exhaust state and scalding the user.

[0050] The present application also provides a cooking utensil, the cooking utensil of the present application includes a cover assembly, wherein the cover assembly is the above-mentioned cover assembly. The above-mentioned cover assembly can effectively solve the problem in the related art that the user has a certain probability of misoperation during cooking, resulting in an error in the state of the pressure limiting valve, and the cooking utensil with the above-mentioned cover assembly also has the above-mentioned advantages.

Unless otherwise specified, these directional words do not indicate or imply that the device or element referred to must have a specific direction or be constructed and operated in a specific direction, and therefore cannot be understood as limiting the scope of protection of the present utility model; the directional words "inside and outside" refer to the inside and outside relative to the contours of each component itself.

[0053] For ease of description, spatially relative terms such as "above", "above", "on the upper surface of", "above", etc. may be used here to describe the spatial positional relationship between a device or feature and other devices or features as shown in the figure. It should be understood that spatially relative terms are intended to include different orientations of the device in use or operation in addition to the orientation described in the figure. For example, if the device in the accompanying drawings is inverted, the device described as "above other devices or structures" or "above other devices or structures" will be positioned as "below other devices or structures" or "below other devices or structures". Thus, the exemplary term "above" can include both "above" and "below". The device can also be positioned in other different ways (rotated 90 degrees or in other orientations), and the spatially relative descriptions used here are interpreted accordingly.

[0054] In addition, it should be noted that the use of terms such as "first" and "second" to limit components is only for the convenience of distinguishing the corresponding components. If not otherwise stated, the above terms have no special meaning and therefore cannot be understood as limiting the scope of protection of the utility model.
