[0002] A pressure cooker is a cooking appliance that can speed up the cooking process by generating high-pressure steam in a sealed cooking chamber. When the heater heats the liquid in the cooking chamber, the liquid begins to generate steam, increasing the pressure in the pot. Due to the presence of high-pressure steam, food can be cooked at a higher temperature, thereby shortening the cooking time. Pressure cookers are suitable for a variety of cooking methods such as stewing, steaming, porridge, and rice, and can preserve the nutrients of food. With the development of technology, smart pressure cookers combine traditional pressure cookers with modern technology, and can automatically control the cooking process through built-in smart chips and sensors. Smart pressure cookers usually have a variety of preset cooking programs. Users only need to select the corresponding program and time to complete the cooking, providing users with a more convenient and intelligent cooking experience.

[0003] In the related art, the smart pressure cooker usually includes a pot body, a sealing device, a pressure detection device, a pressure regulating device and other structures, wherein the pressure detection device can detect the pressure condition in the cooking cavity, and plays a vital role in realizing the high-pressure cooking function of the smart pressure cooker. Usually, the pressure detection device adopts two methods: electronic NTC temperature measurement or mechanical pressure travel switch. If the electronic NTC temperature measurement method is adopted, the deviation of the pressure data detected will be large in areas with high altitudes; if the mechanical pressure travel switch method is adopted, it is usually set at the bottom of the pot body, and can only obtain the on-off signal, and cannot measure the pressure change in real time. Therefore, there is a problem of inaccurate pressure detection of smart pressure cookers in this field. Utility Model Content

[0034] like Figure 1 as well as Figure 2 As shown, the present application provides a cover assembly, and an embodiment of the cover assembly of the present application includes: a cover 10, a sealing structure 20 and a pressure detecting part 30; the cover 10 has a mounting through hole 11 that passes through the upper and lower surfaces of the cover 10; the sealing structure 20 is arranged on the cover 10, and the sealing structure 20 includes an elastic sealing part 21 that blocks the mounting through hole 11; the pressure detecting part 30 is arranged on the cover 10, and the pressure detecting part 30 includes a detecting terminal 31, and the detecting terminal 31 is located above the elastic sealing part 21, and the elastic sealing part 21 can transmit the pressure in the pressure cooking cavity to the detecting terminal 31.

[0035] By applying the technical solution of this embodiment, the cover body 10 is covered on the pot body to form a closed pressure cooking chamber. The cover body 10 has a mounting through hole 11 that passes through the upper and lower surfaces of the cover body 10. The elastic sealing part 21 can block the mounting through hole 11, thereby blocking the steam in the pressure cooking chamber from flowing out to ensure the airtightness of the pressure cooking chamber. The pressure detecting part 30 is arranged on the cover body 10. The detecting terminal 31 on the pressure detecting part 30 can detect the pressure change in the pressure cooking chamber. The detecting terminal 31 is located above the elastic sealing part 21. When the pressure in the pressure cooking chamber changes, the elastic sealing part 21 can transmit the pressure in the pressure cooking chamber to the detecting terminal 31, so that the detecting terminal 31 is subjected to forces of different magnitudes, and then the pressure detecting part 30 detects the pressure change in the pressure cooking chamber. Compared with the solution of using electronic NTC temperature measurement to detect pressure in the related art, the pressure detection unit 30 will not have measurement deviations due to being at different altitudes during use; compared with the solution of using mechanical pressure travel switch to detect pressure in the related art, the pressure detection unit 30 will measure different pressure data due to different pressure conditions in the pressure cooking cavity, thereby more accurately and in real time measuring the pressure in the pressure cooking cavity. Therefore, the technical solution of this embodiment can effectively solve the problem of inaccurate pressure detection of smart pressure cookers in the related art.

[0036] like Figure 1 as well as Figure 2 As shown, the sealing structure 20 also includes a mounting seat 22 mounted at the mounting through hole 11, and the elastic sealing part 21 is mounted on the mounting seat 22. The mounting seat 22 provides a mounting base for the elastic sealing part 21, so that the elastic sealing part 21 can seal the mounting through hole 11 on the one hand, and can transmit the pressure in the pressure cooking cavity to the pressure detection part 30 on the other hand; in this embodiment, the mounting seat 22 is located at the mounting through hole and below the cover body 10. After the pressure detection part 30 is installed, part of the structure of the detection terminal 31 can be located below the cover body 10, so that the detection terminal 31 can extend into the pressure cooking cavity to detect the pressure inside it, and the pressure detection part 30 can occupy as little space as possible inside the cover assembly, so that the additional pressure detection part 30 has little effect on the original structure inside the cover assembly, has the advantage of reasonable layout, and is conducive to the arrangement of the lining cover 50 and the surface cover 60 in the following text. In an embodiment not shown in the figure, the mounting seat can also be arranged above the cover body, the elastic sealing part is installed on the mounting seat, and the detection terminal is located above the elastic sealing part.

[0037] like Figure 1 as well as Figure 2As shown, the elastic sealing part 21 is installed at the bottom of the mounting seat 22 and is located below the cover body 10, the detection terminal 31 extends into the mounting seat 22, and the bottom surface of the detection terminal 31 is located below the cover body 10. The elastic sealing part 21 is installed at the bottom of the mounting seat 22, so that the elastic sealing part 21 can be subjected to vertical pressure, and the elastic sealing part 21 transmits vertical force to the detection terminal 31, without worrying that the detection terminal 31 is subjected to lateral force and causes the detection terminal 31 to move in the lateral direction, so that the pressure in the pressure cooking chamber measured by the pressure detection part 30 is more accurate. The mounting seat 22 can be riveted, welded or connected to the cover body 10 by bolts. In addition, in an embodiment not shown in the figure, the elastic sealing part can also be arranged above the mounting seat, that is, the elastic sealing part is sandwiched between the mounting seat and the lower surface of the cover body.

[0038] like Figure 1 as well as Figure 2 As shown, the mounting seat 22 includes a mounting cylinder 221 and a connecting protrusion 222 arranged around the outside of the mounting cylinder 221, the connecting protrusion 222 is sealed and connected to the cover body 10, the detection terminal 31 is inserted into the mounting cylinder 221, and the elastic sealing part 21 is connected to the connecting protrusion 222. In this embodiment, the mounting cylinder 221 is inserted into the mounting through hole 11 and protrudes upward from the cover body 10, so that the staff can conveniently connect the mounting cylinder 221 to the cover body 10 by riveting. The connecting protrusion 222 provides a mounting base for the elastic sealing part 21, and the connecting protrusion 222 is an annular protrusion. The connecting protrusion 222 is sealed and connected to the cover body 10 to ensure the airtightness of the pressure cooking chamber. The connection between the mounting cylinder 221 and the cover body 10 has the advantage of easy operation. In addition, in an embodiment not shown in the figure, the upper end of the mounting cylinder can be connected to the lower surface of the cover body by welding.

[0039] like Figure 1 as well as Figure 2 As shown, a first mounting groove 2221 is provided on the outer wall of the connecting protrusion 222, and the elastic sealing part 21 comprises a sealing sheet 211, a first connecting section 212 provided at the edge of the sealing sheet 211 and extending upward, and a second connecting section 213 provided at the upper end of the first connecting section 212 and extending inward, the sealing sheet 211 is provided below the mounting cylinder 221, the first connecting section 212 is located outside the connecting protrusion 222, and the second connecting section 213 is inserted into the first mounting groove 2221. The sealing sheet 211 can transmit pressure to the pressure detecting part 30 after being subjected to pressure; the second connecting section 213 is inserted into the first mounting groove 2221, so that when the elastic sealing part 21 is subjected to pressure, the second connecting section 213 is stably inserted into the first mounting groove 2221, thereby ensuring that the elastic sealing part 21 will not easily fall off from the connecting protrusion 222, thereby ensuring the airtightness of the pressure cooking chamber.

[0040] like Figure 1 as well as Figure 2 As shown, the sealing sheet 211 is located below the detection terminal 31, and the distance between the sealing sheet 211 and the bottom of the detection terminal 31 is between 0 and 5 mm. It should be noted that the above-mentioned "the distance between the sealing sheet 211 and the bottom of the detection terminal 31 is between 0 and 5 mm" means that when the pressure cooking chamber is not pressed upward, the distance between the sealing sheet 211 and the bottom of the detection terminal 31 is between 0 and 5 mm. In this embodiment, the sealing sheet 211 mainly seals the pressure cooking chamber and transmits the pressure of the pressure cooking chamber to the detection terminal 31. Preferably, the distance between the sealing sheet 211 and the bottom of the detection terminal 31 is 2 mm, 3 mm or 5 mm, so that the deformation of the sealing sheet 211 is small, so that the elastic sealing part 21 absorbs as little or even no pressure in the pressure cooking chamber as possible, and then the pressure can be transmitted to the detection terminal 31 as much as possible, so that the pressure measured by the pressure detection part 30 is more accurate. Specifically, the elastic sealing part 21 is made of rubber or silicone.

[0041] like Figure 1 as well as Figure 2 As shown, the upper surface of the connecting protrusion 222 is provided with a second mounting groove 2222, and the sealing structure 20 further includes a sealing ring, which is arranged in the second mounting groove 2222 and is sealed with the lower surface of the cover body 10. Specifically, the second mounting groove 2222 is an annular groove, and the sealing ring is arranged in the annular groove and is sealed with the lower surface of the cover body 10, which further ensures the airtightness of the pressure cooking chamber.

[0042] like Figures 1 to 6 As shown, the pressure detection unit 30 also includes a deformation block 32 and a strain gauge disposed on the deformation block 32. The first end of the deformation block 32 is connected to the upper surface of the cover body 10, and the detection terminal 31 is disposed at the second end of the deformation block 32. When the pressure cooking chamber is pressed upward, when the detection terminal 31 moves due to the pressure, the first end of the deformation block 32 is fixed, the deformation block 32 forms a cantilever beam structure, and the second end of the deformation block 32 moves along with the detection terminal 31, thereby causing the strain gauge to deform, thereby causing the resistance value of the strain gauge to change. The pressure detection unit 30 also includes a detection circuit. When the resistance value of the strain gauge changes, the voltage at both ends of the strain gauge measured by the detection circuit will also change. For each voltage value at both ends of the strain gauge, there will be a corresponding pressure value in the pressure cooking chamber, thereby allowing the pressure detection unit 30 to detect continuous pressure changes in the pressure cooking chamber. The pressure in the pressure cooking chamber can be detected in real time by transmitting the steam pressure in the pressure cooking chamber to the pressure detection unit 30, thereby accurately detecting and controlling the heating power of the cooking appliance.

[0043] Specifically, in this embodiment, the detection terminal 31 and the deformation block 32 are separately arranged metal rod structures, which are convenient for processing and assembly of the two. Of course, in an embodiment not shown in the figure, the detection terminal and the deformation block can also be an integrated structure. Under the action of external force, the AD value inside the pressure detection part 30 changes, and the change of the AD value is converted and calculated into a corresponding pressure value. When the cooking program is started, the system can automatically reset it to zero before the pressure is started, so as to control it more accurately. This structure is simple to manufacture, stable and reliable in quality, and has the advantage of accurately detecting pressure.

[0044] like Figures 1 to 6 As shown, the cover assembly further includes a fixing frame 40, the fixing frame 40 includes a fixing sheet 41 and a support member 42 disposed between the fixing sheet 41 and the cover 10, and the pressure detection unit 30 is connected to the fixing sheet 41. Specifically, the support member 42 is a fixing wing disposed on both sides of the fixing sheet 41, and the fixing wing includes a fixing section disposed parallel to the cover 10 and a lifting section disposed perpendicular to the cover 10, and the lifting section lifts the fixing sheet 41, so that the staff can easily connect the pressure detection unit 30 to the fixing sheet 41. The staff can connect the fixing section to the cover 10 by riveting or welding.

[0045] In addition, in this embodiment, the cover assembly further includes a connecting piece 70, the pressure detection part 30 is connected to the top of the connecting piece 70 through a fastener 71, the connecting piece 70 is connected to the fixing piece 41, and the fixing piece 41 is provided with an escape notch 72 for escaping the fastener 71, and the lifting section lifts the fixing piece 41 to form an escape space 73 between the fixing piece 41 and the cover body 10. The fastener 71 is a screw with a large head, which is passed through the connecting piece 70 and the deformation block 32 from bottom to top, and the large head passes through the escape notch 72 and is located in the escape space 73. After the staff completes the connection between the pressure detection part 30 and the connecting piece 70, they connect the connecting piece 70 to the fixing piece 41 through bolts.

[0046] like Figure 3 as well as Figure 6As shown, the cover assembly further includes a lining cover 50 and a surface cover 60. The lining cover 50 is disposed between the cover 10 and the surface cover 60. The lining cover 50 is provided with a relief portion 51 for avoiding the pressure detection portion 30. The relief portion 51 enables the lining cover 50 to avoid the pressure detection portion 30. In addition, the width of the relief portion 51 gradually increases from the inside to the outside. Since the cover 10 needs to rotate relative to the pot body at the beginning or end of cooking, the pressure detection portion 30 will also rotate with the cover 10. The relief portion 51 can continuously avoid the pressure detection portion 30 during the rotation process. Specifically, in this embodiment, the relief portion 51 is a relief port. In other embodiments not shown in the figure, the escape portion can be an upper convex cover body. Specifically, the lining cover is provided with an escape port, and the upper convex cover body includes a panel surrounding the escape port and extending upward, and a top plate provided at the upper end of the panel. The escape port in this embodiment has the same shape as the escape port in the above-mentioned embodiment, so that the lining cover has a complete coverage surface above, which can prevent steam from flowing through the escape port, and can also reduce the sealing components to prevent the influence of steam or soup on the pressure detection part when the exhaust pipe is exhausted. In addition, in other embodiments, the escape portion can also be a groove opened on the lining cover.

[0047] Specifically, in the present embodiment, the cover body 10 is an inner pot cover, on which cover teeth are arranged, and the cover teeth can be engaged with the pot teeth on the pot body to achieve pressure bearing during pressure cooking.

[0048] The present application also provides a cooking utensil, comprising a cover assembly, which is the above-mentioned cover assembly.

[0049] The cooking utensil further comprises a pot body, and a cover assembly is openably and closably arranged on the pot body.
