Description

Technical Field

[0001] The invention relates to the technical field of pressure cookers, and in particular to a pot cover assembly and a floating pressure cooker. Background Art

[0002] Pressure cookers are energy-saving, time-saving, and have multiple cooking functions. They are favored by consumers. Pressure cookers use the physical phenomenon that the boiling point of liquids increases under high pressure to apply pressure to water, allowing the water to reach a higher temperature without boiling, thereby speeding up the efficiency of stewing food. Traditional pressure cookers will have excessive internal pressure when in use, and the pressure relief capacity of the lid is weak. When these pressure relief devices do not work properly, they can cause accidents such as explosions, posing a huge threat to personal safety.

[0003] In the prior art, an exhaust valve is installed on the pot cover as the main pressure relief path, and an exhaust device is installed between the pot cover and the pot body as the secondary pressure relief path. When the exhaust valve does not work properly, the air pressure can push the pot cover open to exhaust and relieve pressure. When the pressure relief device in the related art is relieving pressure, it will cause the pot cover to float up or even be unable to float up, which will cause the pressure relief efficiency to be slow and the pressure relief to be uneven, and there is also a safety risk. Summary of the invention

To this end, the present invention provides a pot cover assembly and a floating pressure cooker, which can make the pot cover float more smoothly and ensure sufficient floating space, so that the exhaust is smoother.

[0006] The deformation part can be elastically deformed when subjected to a set external force, and a distance is provided between the deformation part and the pot cover body.

[0007] In the technical solution, an elastic beam integrated with the pot cover is provided.

[0045] Embodiments of the present invention are described in detail below, examples of which are shown in the accompanying drawings, wherein the same or similar reference numerals throughout represent the same or similar elements or elements with the same or similar functions. The embodiments in the implementation manner are intended to be used to explain the present invention and should not be construed as limiting the present invention.

[0046] References in this specification to "one embodiment" or "an example" or "an example" mean that a particular feature, structure, or characteristic described in conjunction with the embodiment itself may be included in at least one embodiment of the present patent disclosure. The appearance of the phrase "in one embodiment" in various places in the specification does not necessarily refer to the same embodiment.

[0047] See attached Figure 1 , 2One embodiment of the present invention discloses a pot cover assembly, the pot cover assembly 200 includes a pot cover body 201 and an elastic beam 202, the elastic beam 202 is arranged on the back side of the pot cover body 201 (the side away from the pot body when the pot cover body and the pot body are matched), the elastic beam 202 includes a fixing portion 2021 connected to the pot cover body 201 and a deformation portion 2022 extending toward the edge direction of the pot cover body 201, the end of the deformation portion 2022 away from the fixing portion 2021 forms a support end 2023, and the support end 2023 is used to fix the pot cover assembly 200 relative to the pot body 100 when the pot cover assembly 200 is buckled on the pot body 100;

[0048] The deformation portion 2022 can be elastically deformed when subjected to a set external force, and a distance 205 is provided between the deformation portion 2022 and the pot cover body 201 .

[0049] When the pot cover assembly 200 in this embodiment is buckled onto the pot body 100, when the air pressure in the pot body 100 is greater than the set pressure, the pot cover body 201 will float away from the pot body 100 and drive the deformation part 2022 to produce elastic deformation, thereby generating a gap between the pot cover body 201 and the side wall of the pot body 100.

[0050] The elastic beam 202 of the pressure cooker in this embodiment is used as a second-stage pressure relief device. When in use, the pot cover assembly 200 is further provided with an exhaust valve 602 for exhausting air. The exhaust valve 602 is used as a first-stage pressure relief device. When in use, when the air pressure in the pot body 100 is 60-80 KPa, the exhaust valve 602 is used to exhaust air; when the air pressure in the pot body 100 increases to 90-110 KPa, air can be released through the floating of the pot cover assembly 200.

[0051] The working principle of the floating pressure cooker in this embodiment is as follows: when cooking is required, the pot cover assembly 200 is firstly buckled onto the pot body 100, wherein a sealing area is formed between the pot cover body 201 to achieve high-pressure cooking of the food in the pot body 100. When the pressure in the pot body 100 increases to a certain value (>90KPa), the lifting force of the gas pressure in the pot body 100 on the pot cover body 201 is greater than the tensile force of the elastic beam 202 causing deformation. At this time, the pot cover body 201 will move upward. It is fixedly connected to the fixing portion 2021 of the elastic beam 202, thereby driving the fixing portion 2021 of the elastic beam 202 to move upward, and the supporting end 2023 of the elastic beam 202 is relatively fixed to the pot body 100. In order to adapt to the upward floating of the pot body 100 and the fixing portion 2021, the deformation portion 2022 of the elastic beam 202 will produce elastic deformation. It can be seen that during the floating process, the pot cover assembly 200 is always in a connected state with the pot body 100, avoiding the safety risk of the pot cover bursting due to excessive pressure.

[0052] In this embodiment, an elastic beam 202 is provided which is integrated with the pot cover. During the cooking process of the pressure cooker, when the pressure in the pot body 100 is too high, the pot cover can float upward and form a gap between the pot body 100 and the gas in the pot body 100 can escape from the gap to achieve pressure relief, thereby improving the safety of the pressure cooker during use.

[0053] It should be noted that when the pressure in the pot body 100 is too high, the air pressure in the pot body 100 will first act on the pot cover body 201. In actual use, the pot cover body 201 may also produce a certain amount of deformation under the action of the air pressure in the pot body 100, and at the same time, the deformation portion 2022 of the elastic beam 202 will produce a large deformation (it should be noted that the entire elastic beam 202 in the present invention can be set to have elastic material, but because in the actual design, the fixing portion 2021 and the supporting end 2023 of the elastic beam 202 will be fixed, so in actual use, the deformation effect is mainly exerted on the deformation portion 2022. Of course, based on this, in actual setting, only the deformation portion 2022 of the elastic beam 202 can also be set to elastic material). In addition, the elastic beam 202 of the present invention can adopt an elastic metal sheet structure in actual setting.

[0054] During the floating process of the lid assembly 200 of the pressure cooker, the irregular deformation of the lid and the deformation part 2022 may cause the upper end surface of the lid body 201 to collide with the deformation part 2022. At this time, the deformation part 2022 will block the lid body 201 from moving upward, making it difficult for the lid body 201 to float up, and it is impossible to obtain the ideal size gap between the lid body 201 and the pot body 100, which will cause the high-pressure gas in the pot body 100 to be discharged slowly, which may easily lead to safety risks.

[0055] The present invention provides a spacing 205 between the deformation portion 2022 and the pot cover body 201. Figure 1 , 8 The spacing 205 can accommodate the deformation of the pot cover body 201 itself and the deformation of the deformation part 2022, avoiding the contact interference between the pot cover and the elastic beam 202 caused by the irregular deformation of the pot cover and the deformation part 2022 when the pot cover floats up, resulting in the pot cover being unable to float up or the pot cover having difficulty in floating up and unable to reach the predetermined gap. The pot cover can float up smoothly and the gap between the pot cover and the pot body 100 after floating can be guaranteed, thereby improving the air release effect.

[0056] In actual setting, the size of the spacing 205 can also be designed to be no less than the floating amount of the pot cover body 201. The floating amount of the pot cover body 201 in the present invention when in use is 3~5mm. Since the seal 203 has a certain elasticity, if the floating amount of the pot cover body 201 is too small, it may still be in the sealing range of the seal 203. If the floating amount of the pot cover body 201 is too large, it is easy to cause safety risks and easily cause plastic deformation of the elastic beam 202. Therefore, when designing and setting, the spacing 205 between the deformation part 2022 and the pot cover body 201 should also take into account the sealing deformation amount of the seal 203 and the elastic deformation amount of the elastic beam 202. Generally, the spacing 205 is set to be greater than the sealing deformation amount of the seal 203 but not greater than the maximum elastic deformation amount of the elastic beam 202.

[0057] In addition, it should be noted that when the spacing 205 is set, since the space between the pot cover body 201 and the elastic beam 202 has a certain width in the radial direction, the spacing 205 can be set to be distributed with equal spacing 205 over the entire width during design, and of course it can also be set to be distributed with non-equal spacing 205, see the attached Figure 1 , 8 In one embodiment of the present invention, the deformation part 2022 includes an inclined deformation section and a plane section connected to the end of the deformation section, the plane section forms the support end 2023, the plane section and the deformation section have a smooth transition, and the spacing 205 gradually increases from the fixing part 2021 to the support end 2023. The support end 2023 in this embodiment is set as a plane structure, which makes it easier to be fixed and improves the stability of the fixation; the inclined deformation section and the pot cover body 201 can improve the overall strength on the one hand, and can also reduce the overall volume of the pot cover on the other hand, and the spacing 205 gradually increases from the fixing part 2021 to the support end 2023. Since the deformation amount generated by each part of the deformation part 2022 during the floating process is different when the pressure cooker is actually used, by reasonably designing the spacing 205 between each part and the pot cover body 201, it can also ensure that the deformation part 2022 and the pot body 100 are not in contact during the floating process, which can further save space and reduce the volume of the pot cover assembly 200.

[0058] The fixing part 2021 in this embodiment is set as a plane structure (fitted and connected with the plane part on the pot cover body 201 to achieve a more stable connection effect), and a connection hole is opened on the fixing part 2021 for passing the connecting member 206 to achieve the connection between the elastic beam 202 and the pot cover body 201. The connecting member 206 of one embodiment of the present invention is set at the center of the fixing part and the pot cover body, so that when connecting, only one connecting member 206 needs to be set at the center to achieve a reliable connection between the two.

[0059] The supporting end 2023 of the elastic beam 202 in the present invention can be directly fixed on the pot body 100, so that when in use, the versatility of the pot cover assembly 200 can be improved, and the pot cover assembly 200 can be suitable for any pressure cooker body with the same caliber.

[0060] The two ends of the elastic beam of the present invention extend to the edges of the two sides of the pot cover body respectively and form two symmetrically distributed deformation parts. When in use, the pot cover assembly can float up and down as a whole (not deflected on one side), so that the gap between the pot cover assembly and the pot body in the circumference is uniform, and the stability of the deflation and the deflation efficiency are improved.

[0061] The second aspect of the present invention discloses a floating pressure cooker, comprising a pot body 100 and a pot cover assembly 200 of the first aspect, the pressure cooker further comprising a locking mechanism for locking the pot cover assembly 200 and the pot body 100, the locking mechanism comprising a first locking member arranged on the pot body 100 and a second locking member arranged on the pot cover assembly 200, the locking mechanism being capable of fixing the support end 2023; the pot cover assembly 200 further comprising a manipulation component for switching the second locking member between a locking position and an unlocking position; in the locking position, the pot cover assembly 200 can be locked on the pot body 100 by the locking mechanism; in the unlocking position, the pot cover assembly 200 can be separated from the pot body 100.

[0062] The locking mechanism of the present invention can not only realize the locking of the pot cover assembly 200 and the pot body 100, but also fix the supporting end 2023 of the elastic beam 202 on the pot body 100. In this way, when the pressure in the pot body 100 is too large, the supporting end 2023 of the elastic beam 202 is equivalent to providing a deformation fixing point for the elastic beam 202, thereby preventing the elastic beam 202 from being separated from the pot body 100 due to the elastic deformation tension caused by the air pressure rise, thereby improving the safety of the pressure cooker.

[0063] The locking mechanism of the present invention has various forms. The present invention provides the following embodiments: 1. Figure 1 , 4, 6, 7, the first locking member of one embodiment of the locking mechanism of the present invention includes a flange 301 extending outward from the open end of the pot body 100, and the second locking member includes a movable hook 302, the movable hook 302 includes a hook 3022 body 3021 movably mounted on the elastic beam 202 and a hook 3022 arranged on the hook 3022 body 3021, and the hook 3022 extends toward the edge of the pot cover body 201; in the locked position, the hook 3022 can be hooked on the lower end of the flange 301 from the outside of the pot body 100 to lock the pot cover assembly 200 on the pot body 100, and the support end 2023 of the deformation portion 2022 is clamped and fixed by the hook 3022 body 3021 and the flange 301.

[0064] The first locking member in this embodiment adopts the flange 301 structure formed by the pot body 100 itself, and there is no need to add other accessories or structures on the pot body 100. The second locking member on the pot cover assembly 200 is set to a structure of a movable hook 302 adapted to the flange 301. The movable hook 302 in this embodiment is installed on the top surface of the elastic beam 202. Of course, in actual settings, the first locking member can also be installed on other components (for example, an intermediate component for installing the first locking member is added to the elastic beam 202). The first locking member is a movable member, and the switching between the unlocked position and the locked position is realized through the activity of the first locking member. In contrast, it should be noted that the structure in which the movable hook 302 and the flange 301 cooperate in the present embodiment is fixed to the pot body 100 from the outside, and the supporting end 2023 of the elastic beam 202 is clamped and fixed by the hook 3022 body 3021 and the flange 301. When the pressure cooker floats and causes the elastic beam 202 to stretch, since the elastic beam 202 and the movable hook 302 are connected as a whole, the greater the elastic deformation of the elastic beam 202, the greater the force applied to the movable hook 302 body in the vertical direction. In this way, the clamping effect of the movable hook 302 on the elastic beam 202 is more stable, thereby further improving safety.

[0065] In addition, it should be noted that, because the movable hook 302 and the flange 301 are hooked and fixed, when the pot cover assembly 200 floats upward, deformation will occur at the locking position, causing the contact surface to change from a surface to a point, which will cause the risk of decoupling. In the actual setting of this embodiment, the hook 3022 of the movable hook 302 can be set as shown in the attached figure. Figure 6 The structure with a certain width shown in the figure can turn the contact surface into a line contact when floating, thereby increasing the contact area and reducing the risk of unhooking. Of course, the hook 3022 can also be further configured as an arc structure that imitates the flange 301 of the pot body 100, which can further enhance the connection effect.

[0066] 2. See Attachment Figure 8In one embodiment of the locking mechanism of the present invention, the first locking member includes a through hole 401 arranged on the side wall of the pot body 100, and the second locking member includes a movable plug plate 402, the movable plug plate 402 includes a plug plate body 4021 movably mounted on the elastic beam 202 and an insertion end 4022 arranged at one end of the plug plate body 4021, and the insertion end 4022 extends toward the edge of the pot cover body 201; in the locking position, the insertion end 4022 can be inserted into the through hole 401 from the inner side of the pot body 100 to lock the pot cover assembly 200 on the pot body 100, and the support end 2023 is clamped and fixed by the movable plug plate 402 and the through hole 401.

[0067] The first locking member in the present embodiment is configured as a through hole 401 opened on the side wall of the pot body 100. Similarly, there is no need to add other accessories to the pot body 100. The position of the through hole 401 is generally located between the end of the open end of the pot body 100 and the sealing area of ​​the pot cover assembly 200 and the pot body 100. The second locking member on the pot cover assembly 200 is configured as a structure of a movable plug plate 402 that is compatible with the through hole 401. Similarly, the movable plug plate 402 in the present embodiment is configured as a structure directly connected to the elastic beam 202. When in use, the movement of the movable plug plate 402 enables it to be inserted into the through hole 401 or detached from the through hole 401, thereby realizing switching between the locked position and the unlocked position. Similarly, when the pressure cooker floats and the elastic beam 202 is stretched, since the elastic beam 202 and the movable plate 402 are connected as one body, the greater the elastic deformation of the elastic beam 202, the greater the force applied to the movable plate 402 in the vertical direction, so that the clamping effect of the movable plate 402 on the elastic beam 202 is more stable, further improving safety. In addition, this embodiment locks the pot cover assembly 200 and the pot body 100 from the inside of the pot body 100, and when the deformation part 2022 of the elastic beam 202 is deformed, the support end 2023 of the elastic beam 202 is less likely to be separated from the pot body 100, further improving the safety effect.

[0068] See attached Figure 8 , 9 , 10, 11, in order to better adapt to the connection between the through hole 401 and the movable plug plate 402 in this embodiment, a positioning hole is provided on the handle 604 on the pot body 100, and a positioning block corresponding to the positioning hole is provided on the edge of the pot cover assembly 200. When the pot cover assembly 200 is buckled on the pot body 100, the positioning block is inserted into the positioning hole to achieve relative fixation of the positions of the pot cover assembly 200 and the pot body 100. At this time, the positions of the movable plug plate 402 and the through hole 401 on the pot body 100 correspond to each other, avoiding the problem that the movable plug plate 402 cannot be inserted into the through hole 401 due to installation error.

[0069] Since the second locking member of the present invention is a movable member, the stability and firmness of its installation are directly related to the locking effect of the pot cover assembly 200 and the pot body 100. In order to improve the stability of the installation of the second locking member, the elastic beam 202 of the present invention is provided with a first installation portion for slidingly installing the second locking member on the side away from the pot body 100, and the elastic beam 202 includes baffles 2024 protruding from the two side edges of the elastic beam 202, and the two baffles 2024 are located on both sides of the first installation portion. The protruding ends of the baffles 2024 are formed with bending portions 2025 folded toward the first installation portion, and the main body of the second locking member is slidably installed on the first installation portion. During installation, the positions of the two side portions of the second locking member are limited by the baffles 2024 on both sides, the bottom of the second locking member is limited by the top surface of the elastic beam 202, and the top is limited by the bending portion 2025, thereby achieving a stable installation effect of the second locking member and improving the stability of the installation and movement of the second locking member.

[0070] It should be noted that, in actual use, the bending portion 2025 or the baffle 2024 provided on the elastic beam 202 can not only improve the installation stability of the second locking member, but also improve the structural strength of the elastic beam 202 itself (at this time, the baffle 2024 and the bending portion 2025 are equivalent to the structure of the reinforcing rib).

[0071] It should be noted that the number of the second locking members in the present invention is set to two, and the two second locking members are symmetrically distributed. Figure 5 , 8 The middle part of the elastic beam 202 can also form a concave fixing part 2021, and the two ends of the elastic beam 202 extend to the two sides of the pot cover body 201 to form the supporting ends 2023, and the bottom surface of the fixing part 2021 and the top surface of the pot cover body 201 are attached to each other and fixedly connected, and the two supporting ends 2023 can be fixed synchronously relative to the pot body 100. The strength of the elastic beam 202 is improved, and the pot cover assembly 200 can float stably as a whole when floating, and after floating, it can be evenly deflated in the circumference of the pot cover body 201, thereby improving the deflation efficiency.

[0072] The movement of the second locking member of the present invention is realized by a manipulation component. In actual configuration, the manipulation component has various forms. Several commonly used embodiments of the manipulation component are listed below:

[0073] 1. See Appendix Figure 1 , 2, 8, 9, the operating component includes a turntable 501 and a knob 5012 fixedly connected to the turntable 501, the fixed portion 2021 of the elastic beam 202 is formed with a second mounting portion for mounting the turntable 501, the turntable 501 is rotatably mounted on the second mounting portion, a driving groove 5011 is provided on the turntable 501, one end of the second locking member is provided with a protrusion 5013 with one end inserted into the driving groove 5011, the driving groove 5011 includes a locking segment 5011a for placing the second locking member in a locked position and an unlocking segment 5011b for placing the second locking member in an unlocked position; the locking segment 5011a and the unlocking segment 5011b have a smooth transition, and the rotation of the turntable 501 can cause the protrusion 5013 to slide between the locking segment 5011a and the unlocking segment 5011b, so that the second locking member switches between the locked position and the unlocked position.

[0074] In this embodiment, when the control component is in use, the user rotates the knob 5012 (the knob 5012 protrudes from the pot cover assembly 200, see the attached Figure 2 , 8 ), the knob 5012 will drive the turntable 501 to rotate, and the rotation of the turntable 501 drives the reciprocating movement of the second locking member through the cooperation of the driving groove 5011 and the protrusion 5013. The movement range of the second locking member can be well controlled by setting the shape of the driving groove 5011, wherein the present invention sets the locking position and the unlocking position to an area covering a certain width by setting the shape of the driving groove 5011, so that when the second locking member and the first locking member on the pot body 100 are locked, they will not be unlocked due to the slight shaking of the second locking member, which can improve the locking stability.

[0075] See attached Fig.12, 2. This embodiment is suitable for the synchronous action of two symmetrically distributed second locking members, and the control component includes a button 502, a first movable plate 5021, and a second movable plate 5022. When set, the first movable plate 5021 and the second movable plate 5022 are respectively connected to the two symmetrically distributed second locking members, wherein a first beveled tooth with a first inclined surface and a second beveled tooth with a second inclined surface are provided at the bottom of the button 502; the first movable plate 5021 is provided with a third beveled tooth with a third inclined surface, and the second movable plate 5022 is provided with a fourth beveled tooth with a fourth inclined surface, wherein the first beveled tooth and the third beveled tooth are arranged opposite to each other, and the second beveled tooth and the fourth beveled tooth are arranged opposite to each other; when the button 502 is pressed downward, the first beveled surface abuts and cooperates with the third beveled surface so that the button 502 can drive the first movable plate 5021, and the second beveled surface abuts and cooperates with the fourth beveled surface so that the button 502 can drive the second movable plate 5022, so that the synchronous telescopic movement of the two symmetrically distributed second locking members can be achieved. A first return spring 5023 may be provided between the first movable plate 5021 and the second movable plate 5022 to facilitate the return of the second locking member.

[0076] 3. See Attachment Fig.13 The control component in this embodiment is configured as two pressing blocks 503 and a first turntable 5031. The two pressing blocks 503 are connected to the first turntable 5031. The two pressing blocks 503 move closer to or farther from each other to rotate the turntable.

[0077] In this embodiment, when the user squeezes the two pressing blocks 503 toward the middle, the two pressing blocks 503 will apply a rotational torque to the first rotating disk 5031, so that the first rotating disk 5031 rotates counterclockwise or clockwise. This rotation action will drive other components connected to the first rotating disk 5031 (the first locking member is connected to the driving groove 5011 of the first rotating disk 5031 through the protrusion 5013) to perform corresponding movements, thereby realizing the switching of the first locking member between the unlocking position and the locking position. A second return spring 5032 can also be configured between the two pressing blocks 503. When the user operates the pressing block 503 to drive the first rotating disk 5031 to rotate, the second return spring 5032 will be compressed or stretched. Once the user releases the pressing block 503, the second return spring 5032 will quickly return to its original shape, thereby driving the pressing block 503 back to the initial position. The control component in this embodiment is applicable to the structure in which the first locking member is a flange 301 and the second locking member is a movable hook 302 mentioned above in the present invention.

[0078] Of course, there are many other forms of the operating component that can drive the first locking member to slide back and forth, which will not be elaborated here.

[0079] One embodiment of the present invention corresponding to the structure in which the control component is a knob 5012 and a turntable 501 is as follows: the pot cover assembly 200 further includes a check valve 601 arranged on the pot cover body 201, the check valve 601 is placed below the turntable 501, a check valve hole 5014 is opened on the turntable 501, and the check valve hole 5014 is arranged in an arc structure around the center of the turntable 501; the first valve hole end 5014a of the check valve hole 5014 Corresponding to the locking section 5011a, the second valve hole end 5014b of the stop valve hole 5014 corresponds to the position between the locking section 5011a and the unlocking section 5011b; when the valve core of the stop valve 601 is placed at the first valve hole end 5014a, the second locking member is placed at the end position of the locking section 5011a; when the valve core of the stop valve 601 is placed at the second valve hole end 5014b, the second locking member is placed in the middle of the locking section 5011a.

[0080] The design of the check valve 601 in this embodiment is equivalent to adding a safety device. The check valve 601 can limit the movement of the second locking member to the unlocking position when the pressure in the pot body 100 is too high, thereby avoiding the safety risks that may arise when opening the pot lid under high pressure.

[0081] On the basis of the check valve 601, the pot cover assembly 200 of the present invention is also provided with an exhaust valve 602, and the exhaust valve 602 includes a movably installed exhaust valve core and a pushing member 603 connected to one side of the exhaust valve core, and the turntable 501 is provided with a groove opposite to the end of the pushing member 603, and the side wall of the groove is provided with a slope 5015; when the second locking member is in the locking section, the rotation of the turntable 501 can push the pushing member 603 through the slope 5015 to drive the exhaust valve core to move.

[0082] When in use, the exhaust valve 602 is used as a first-stage air release device, which is suitable for exhausting when the pressure in the pot body 100 is 60-80KPa. When the exhaust valve 602 fails and cannot exhaust, the pot cover body 201 will float upward, wherein the exhaust of the exhaust valve 602 is performed autonomously by the user, and the user can rotate the knob 5012 to drive the turntable 501 to rotate, and the rotation of the turntable 501 can lift the valve core of the exhaust valve 602 through the pusher 603, thereby achieving exhaust. This embodiment combines the actions of the exhaust valve 602 and the turntable 501, so that the connection between the components is closer and the overall structure is more compact.

[0083] The pot cover assembly 200 of the present invention further comprises a panel 204, which is disposed on the pot cover body and can cover the turntable 501, the elastic beam 202 and the second locking member, and the knob 5012 and the exhaust valve 602 have a portion protruding from the panel 204. The protruding structure design of the knob 5012 facilitates the operation of the user, and the panel 204 can improve the overall appearance of the pot cover assembly 200 and the pressure cooker. A handle 604 can also be provided on the outer side wall of the pot body 100 of the present invention.

[0084] The structure of the pot body 100 of the present invention may include a first straight cylinder 101, a conical cylinder 102, a second straight cylinder 103 and a bottom plate 104 connected in sequence, one end of the first straight cylinder 101 forms an opening of the cooking cavity of the pot body 100, and an annular seal 203 is provided at the edge of the pot cover body 201; the inner wall of the conical cylinder 102 can be sealed with the seal 203.

[0086] The above are only specific embodiments of the present invention, but the protection scope of the present invention is not limited thereto. Those skilled in the art should understand that the present invention includes but is not limited to the contents described in the drawings and the above specific embodiments. Any modification that does not deviate from the functional and structural principles of the present invention will be included in the scope of the claims.
