[0002] There is an existing cooking device consisting of a pot body, a heating tube and a bottom cover. The heating tube and the bottom cover are arranged on the bottom surface of the pot body, and the center of the bottom cover is fixed to the pot body by screws. During the use of this type of cooking device, there is a possibility that the thermostat fails and the heating tube does not stop working in time. The accumulated heat causes the pot body to be overheated and deformed. As a result, a gap is easily formed between the bottom cover and the bottom surface of the pot body, causing a large amount of heat to overflow from the gap, causing burns and other hazards to the user. This safety issue needs to be urgently addressed. Summary of the Invention

[0003] In order to solve the above technical problems or at least partially solve the above technical problems, the present application provides a cooking appliance.

[0004] The present application provides a cooking utensil, comprising a pot body, a heating element, a bottom cover and a plurality of supporting legs, wherein the heating element is arranged on the pot body, the bottom cover and the plurality of supporting legs are fixed on the bottom surface of the pot body, the plurality of supporting legs are arranged around the bottom cover, and a fixing piece is provided on the side wall of at least one of the supporting legs, and the fixing piece abuts against the bottom cover so that the bottom cover is clamped between the fixing piece and the pot body.

[0005] In some embodiments, the bottom cover includes a cover body and a flange arranged around the cover body, a cavity is formed between the cover body and the bottom surface of the pot body, and the flange is arranged to fit the bottom surface of the pot body.

[0006] In some embodiments, the upper surface of the fixing member abuts against the bottom surface of the flange.

[0007] In some embodiments, the upper surface of the fixing member abuts against the bottom surface of the cover.

[0008] In some embodiments, the number of the supporting legs is an even number, and the supporting legs are symmetrically arranged in pairs about the center of the bottom cover, the upper surface of the fixing member abuts against the bottom surface of the cover body, and the two ends of the fixing member are respectively connected to the side walls of the two symmetrically arranged supporting legs.

[0009] In some embodiments, a mica sheet is further included below the heating element. The mica sheet is disposed in the cavity and is fixedly connected to the pot body.

[0010] In some embodiments, the fixing member and the supporting foot are integrally formed.

[0011] In some embodiments, the fixing member is slidably connected to the supporting leg, and the fixing member can slide along the axial direction of the supporting leg.

[0012] In some embodiments, the fixing member is retractable along the radial direction of the supporting foot.

[0013] In some embodiments, a buffer layer is provided on the upper surface of the fixing member, and the buffer layer is in contact with the bottom cover.

[0014] The technical solution provided by the embodiments of the present application has the following advantages compared with the prior art:

[0015] The cooking utensil provided in an embodiment of the present application includes a pot, a heating element, a bottom cover, and a plurality of supporting legs. The heating element is disposed on the pot, and the bottom cover and the plurality of supporting legs are fixed to the bottom surface of the pot. The plurality of supporting legs are arranged around the bottom cover, and a fixing member is provided on the side wall of at least one of the supporting legs. The fixing member abuts the bottom cover so that the bottom cover is clamped between the fixing member and the pot. During the die-casting process, the pot body may be slightly deformed by drawing the die or processing the material mouth. The uneven bottom of the pot body may cause a gap between the pot body and the bottom cover. The embodiment of the present application adds fixing members to the supporting legs so that the fixing members abut the bottom cover, thereby increasing the number of fixing points for the bottom cover. Even if the pot body is deformed, a gap is unlikely to form between the pot body and the bottom cover, ensuring uniform heating of the pot body. This solves the safety problem of burns to the user caused by the bottom cover shifting due to pot body deformation or the increase in the gap between the bottom cover and the pot body, thereby improving the safety performance of the cooking utensil.

[0016] The bottom cover is configured to comprise a cover body and a flange. When the flange is aligned with the bottom surface of the pot, a cavity is formed between the cover body and the bottom surface of the pot. When the cooking appliance is in operation, the heating element heats the cooking cavity within the pot, thereby increasing the cooking temperature within the cooking cavity. Excess heat generated by the heating element enters the cavity between the bottom cover and the pot body, and the bottom cover reflects the heat within the cavity back to the cooking cavity, thereby ensuring more even heating within the cooking cavity.

[0017] When the upper surface of the fixing piece abuts against the bottom surface of the flange, the length of the fixing piece can be made relatively short. The stability of the connection structure between the bottom cover and the pot body is improved by reinforcing at multiple points on the bottom cover, thereby preventing the bottom cover from separating from the pot body. At the same time, because the length of the fixing piece is relatively short, raw materials are saved to a certain extent, and production costs are controlled.

[0018] When the upper surface of the fixing member abuts against the bottom surface of the cover body, it is equivalent to the fixing member providing an upward pressure to the entire bottom cover below the bottom cover, so that the bottom cover can be locked with the pot body more stably, thereby improving the stability of the connection structure between the two.

[0019] The number of supporting legs is set to an even number, and pairs of them are symmetrically arranged about the center of the bottom cover. The upper surface of the fixing member abuts the bottom surface of the cover, and the ends of the fixing member are respectively connected to the side walls of the two symmetrically arranged supporting legs. The multiple fixing members form a cross-shaped or cross-shaped structure, abutting the bottom surface of the cover, clamping the bottom cover between the pot body and the fixing members. Even if the pot body deforms, the fixing members can cause the pot body to collapse downward, and a gap is unlikely to form between the pot body and the bottom cover, thereby ensuring the performance of the cooking appliance.

[0020] A mica sheet is provided in the cavity between the cover and the pot body. The mica sheet has good thermal insulation performance, which effectively prevents the heat generated by the heating element from being transferred downward, ensuring heat utilization efficiency.

[0021] The fixing part and the supporting leg are made by an integrated molding process, which simplifies the manufacturing process of the fixing part and also avoids the connection operation between the fixing part and the supporting leg.

[0022] The fixing member is arranged to be slidably connected to the supporting foot, so that the relative position of the fixing member and the supporting foot along the axial direction can be adjusted, and the fixing of bottom covers of different heights can be applied.

[0023] The fixing member is arranged to be retractable along the radial direction of the supporting foot, so that the length of the fixing member can be adjusted, and thus the contact area between the fixing member and the bottom cover can be adjusted.

[0024] A buffer layer is provided on the upper surface of the fixing member to avoid hard contact between the hard fixing member and the bottom cover, thereby protecting the bottom cover. BRIEF DESCRIPTION OF THE DRAWINGS

DETAILED DESCRIPTION

[0039] In order to more clearly understand the above-mentioned objectives, features and advantages of the present application, the scheme of the present application will be further described below. It should be noted that, in the absence of conflict, the embodiments of the present application and the features therein can be combined with each other.

[0040] In the following description, many specific details are set forth to facilitate a full understanding of the present application, but the present application can also be implemented in other ways different from those described herein; it is obvious that the embodiments in the specification are only part of the embodiments of the present application, not all of the embodiments.

[0041] In addition, in the description of the present application, it should be understood that the terms "top", "bottom", "inside", "outside", "axial", "radial", "circumferential", etc., indicating orientations or positional relationships, are based on the orientations or positional relationships shown in the accompanying drawings. They are only for the convenience of describing the present application and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation. Therefore, they cannot be understood as limitations on the present application.

[0042] In this application, unless otherwise expressly specified or limited, terms such as "installed," "connected," "connect," and "fixed" should be understood in a broad sense. For example, they may refer to fixed connection, detachable connection, or integration; mechanical connection, electrical connection, or communication; direct connection or indirect connection through an intermediate medium; and internal communication between two components or interaction between two components. Those skilled in the art will understand the specific meanings of the above terms in this application based on specific circumstances.

[0043] In this application, unless otherwise expressly specified and limited, a first feature "above" or "below" a second feature may be that the first and second features are in direct contact, or the first and second features are in indirect contact through an intermediate medium. In the description of this specification, the description with reference to the terms "one embodiment", "some embodiments", "example", "specific example", or "some examples" means that the specific features, structures, materials or characteristics described in conjunction with the embodiment or example are included in at least one embodiment or example of the present application. In this specification, the schematic representation of the above terms does not necessarily refer to the same embodiment or example. Moreover, the specific features, structures, materials or characteristics described may be combined in an appropriate manner in any one or more embodiments or examples.

[0044] During the die-casting process, the pot body of the electric hot pot is slightly deformed due to the pulling of the die or the processing of the material mouth. Since the bottom cover is only fixed to the pot body by screws at the center, when the pot body is deformed, a gap will appear in the normal fit between the pot body and the bottom cover, causing the temperature rise data of the pot body to exceed the standard, and at the same time affecting the aesthetics of the appearance.

[0045] In addition, when the electric hot pot thermostat fails, the fuse acts as the last line of protection. Due to the high temperature in the pot body, the pot body deforms and collapses downward under the action of gravity. The screw column fixing the bottom cover in the center of the pot body collapses downward towards the center of the pot body, and moves the bottom cover downward and separates from the pot body. A large amount of heat will be released around the pot body and the bottom cover, which can easily burn the human body and cause a safety hazard.

[0046] In order to solve the problem of gaps easily appearing between the bottom cover 3 and the pot body 1, an embodiment of the present application provides a cooking utensil, which adds a fixing part 401 to the existing supporting foot 4 to fix the bottom cover 3, thereby improving the assembly stability between the bottom cover 3 and the pot body 1 and avoiding the problem of gaps appearing between the bottom cover 3 and the pot body 1 during use and testing.

[0047] The present application does not limit the type of cooking appliances, including but not limited to rice cookers, pressure cookers, electric stew pots, electric baking pans, electric hot pots, grilling machines, etc. The present application embodiment takes an electric hot pot as an example for description.

[0048] For example, Figures 1 to 11 As shown, the cooking utensil provided in the embodiment of the present application includes a pot body 1, a heating element 5, a bottom cover 3 and a plurality of supporting legs 4, the heating element 5 is arranged on the pot body 1, the bottom cover 3 and the plurality of supporting legs 4 are fixed on the bottom surface of the pot body 1, the plurality of supporting legs 4 are arranged around the bottom cover 3, and a fixing member 401 is provided on the side wall of at least one supporting leg 4, the fixing member 401 abuts against the bottom cover 3 so that the bottom cover 3 is clamped between the fixing member 401 and the pot body 1.

[0049] It should be noted that the support leg 4 is cylindrical in shape, and the axial direction of the support leg 4 is perpendicular to the bottom surface of the pot body 1, and the radial direction of the support leg 4 is parallel to the bottom surface of the pot body 1. For example, Figure 1 As shown, in some embodiments of the present application, the diameter of the end of the supporting foot 4 close to the pot body 1 is slightly larger than the diameter of the end away from the pot body 1, and the end face of the supporting foot 4 close to the pot body matches the bottom surface contour of the pot body 1. After the installation is completed, the end face of the supporting foot 4 close to the pot body 1 is fitted with the bottom surface of the pot body 1, and the end face of the supporting foot 4 away from the pot body 1 is set to a smooth arc surface.

[0050] The interior of the pot body 1 may define a cooking space. The heating element 5 may be disposed below the pot body 1 to heat the cooking cavity. The bottom cover 3 may be disposed below the pot body 1 and cooperate with the pot body 1 to define a cavity. At least a portion of the heating element 5 may be located within the cavity. The "below" in the above description may include the bottom of the pot body 1 and the lower portion of the sidewalls of the pot body 1. The heating element 5 may directly heat the bottom of the pot body 1 or extend to the sidewalls of the pot body 1 to provide three-dimensional heating of the pot body 1.

[0051] The supporting foot 4 is provided with a connecting hole along the axial direction, and the bottom surface of the pot body 1 protrudes downward to form a first screw column 101. The first screw 6 passes through the connecting hole and is locked with the first screw column 101 to fix the supporting foot 4 on the bottom surface of the pot body 1 to support the pot body 1.

[0052] When the cooking appliance is in operation, the heating element 5 heats the pot 1, thereby increasing the cooking temperature within the cooking space. Excess heat generated by the heating element 5 enters the cavity, and the bottom cover 3 prevents the heat from escaping, concentrating it within the cavity and heating the pot 1. This ensures more uniform heating of the pot 1. In some embodiments, the bottom cover 3 is made of a thermally insulating material to better prevent heat loss and improve heat utilization. Alternatively, the bottom cover 3 is made of a metal material for easier processing and molding.

[0053] The center of the pot body 1 protrudes downward to form a second screw column 102, and a second connecting hole 301 is provided in the center of the bottom cover 3. The second screw 7 passes through the second connecting hole 301 and is fastened to the second screw column 102 to achieve locking with the pot body 1. Since the bottom cover 3 is only fastened to the pot body 1 by the second screw 7 set in the center, when the temperature of the pot body 1 is too high or during abnormal testing, the center of the pot body 1 collapses downward and deforms, which can easily cause a gap to appear between the pot body 1 and the bottom cover 3, thereby affecting the temperature rise data of the side wall of the pot body 1. By adding fixing members 401 to support legs 4, fixing members 401 abut against bottom cover 3, increasing the number of fixing points for bottom cover 3. Fixing members 401 provide support toward the pot body through abutment, thereby clamping bottom cover 3 between fixing members 401 and pot body 1. Even if pot body 1 deforms, a gap is unlikely to form between pot body 1 and bottom cover 3, ensuring uniform heating of pot body 1 and preventing heat from being released from between pot body 1 and bottom cover 3, thus ensuring safety in use. Furthermore, the absence of a gap between the two also ensures the aesthetic appearance of the cooking utensil.

[0054] The heating element 5 can be a heating plate or heating wire or other electrically heated structure. The heating element 5 is laid as evenly as possible on the bottom surface of the pot body 1. In some embodiments, the heating element 5 is fitted with the central area of ​​the bottom of the pot body 1 to maintain contact heat transfer to the pot body 1, providing a basis for heating the food in the cooking space.

[0055] like Figures 3 to 5As shown, in some embodiments of the cooking utensils provided herein, the bottom cover 3 includes a cover body 32 and a flange 31 surrounding the cover body 32. A cavity is formed between the cover body 32 and the bottom surface of the pot body 1, and the flange 31 is aligned with the bottom surface of the pot body 1. Exemplarily, the cover body 32 is a cylindrical shell structure with an open upper end and a closed lower end. The upper edge of the cover body 32 is bent outward to form the flange 31. The cover body 32 is buckled onto the bottom surface of the pot body 1. The flange 31 is aligned with the bottom surface of the pot body 1, and a certain distance is provided between the lower end surface of the cover body 32 and the pot body 1. Therefore, a cavity is formed between the cover body 32 and the bottom surface of the pot body 1. The cavity can collect heat generated by the heating element 5, improving the heating effect on the pot body 1. At the same time, it reduces the contact area between the bottom cover 3 and the pot body 1, preventing large-area contact between the bottom cover 3 and the pot body 1 from causing deformation or damage to the bottom cover 3, which could affect the performance of the bottom cover 3.

[0056] It should be noted that the height of the bottom cover 3 is smaller than the height of the supporting legs 4. In this way, after the cooking utensil is assembled, the supporting legs 4 are in contact with the table top, and there is a certain gap between the bottom cover 3 and the table top, ensuring that the cooking utensil can be placed stably during use without causing damage to the bottom cover 3.

[0057] like Figure 3 and Figure 4 As shown, in some embodiments of the present application, the upper surface of the fixing member 401 abuts against the bottom surface of the flange 31, that is, the fixing member 401 locks the bottom cover 3 at the edge of the bottom cover 3. Figure 6 As shown, multiple support legs 4 are arranged around the bottom cover 3 along the circumference of the bottom cover 3, and the inner side of the support legs 4 is arranged adjacent to the edge of the flange 31 of the bottom cover 3. A protrusion protrudes from the inner side of the support legs 4 to form a fixing part 401 that abuts against the bottom surface of the flange 31. The bottom surface of the flange 31 is the surface of the flange 31 away from the pot body 1.

[0058] Among the multiple supporting legs 4, only some of them may be formed with fixing parts 401, or all of them may be formed with fixing parts 401. The fixing parts 401 may cooperate with the screws in the center of the bottom cover 3 to lock the bottom cover 3, or the bottom cover 3 may be locked only by the fixing parts 401. The fixing parts 401 are distributed as evenly as possible along the circumference of the bottom cover 3 to improve the stability of the fixation of the bottom cover 3.

[0059] like Figure 7 As shown, in some embodiments of the present application, the upper surface of the fixing member 401 abuts against the bottom surface of the cover body 32. Figure 3 Compared with the fixing member 401, Figure 4The length of the fixing member 401 is longer, and the distance between its upper surface and the bottom surface of the pot body 1 is also larger. The force application point of the fixing member 401 acts on the bottom surface of the cover body 32, and the contact area with the bottom cover 3 is also larger. It is equivalent to that the fixing member 401 provides an upward pressure for the entire bottom cover 3 below the bottom cover 3, so that the bottom cover 3 can be locked with the pot body 1 more stably, thereby improving the stability of the connection structure between the two.

[0060] Furthermore, in some embodiments of the present application, the number of support legs 4 is set to an even number, and the even-numbered support legs 4 are symmetrically arranged in pairs about the center of the bottom cover 3. The upper surface of the fixing member 401 abuts the bottom surface of the cover body 32, and the two ends of the fixing member 401 are respectively connected to the side walls of the two symmetrically arranged support legs 4. Specifically, the fixing member 401 is relatively long, and when abutting the bottom surface of the cover body 32, the multiple fixing members 401 form a cross-shaped or cross-shaped structure, abutting the bottom surface of the cover body 32, clamping the bottom cover 3 between the pot body 1 and the fixing members 401. Even if the pot body 1 is deformed, under the action of the fixing members 401, even if the pot body 1 collapses downward, it is unlikely to form a gap between the pot body 1 and the bottom cover 3, thereby ensuring the performance of the cooking appliance. The length of the fixing part 401 is relatively short, and when it abuts against the bottom surface of the flange 31, the supporting feet 4 are symmetrically arranged in pairs about the center of the bottom cover 3, and each supporting foot 4 is provided with a fixing part 401. In the circumferential direction around the flange 31, multiple fixing parts 401 can also lock the bottom cover 3 at the edge position of the bottom cover 3, thereby improving the stability of the fixing structure of the bottom cover 3.

[0061] For example, Figure 7 As shown, in some embodiments of the present application, the number of supporting legs 4 is 4, and the fixing member 401 is in a "cross" shape and abuts against the bottom surface of the cover body 32, providing an upward pressure to the cover body 32, thereby fixing the bottom cover 3 on the pot body 1.

[0062] In some embodiments of the present application, the cooking appliance further includes a mica sheet 2 located below the heating element 5. The mica sheet 2 is disposed in the cavity and is fixedly connected to the pot body 1. The mica sheet 2 has good thermal insulation properties, effectively preventing the heat generated by the heating element 5 from being transferred downward, thereby ensuring efficient heat utilization.

[0063] In some embodiments of the present application, the fixing member 401 and the supporting foot 4 are integrally formed, which avoids the connection operation between the fixing member 401 and the supporting foot 4, simplifies the production process of the fixing member 401, thereby improving production efficiency and saving production costs.

[0064] In some embodiments of the present application, the fixing member 401 is slidably connected to the supporting foot 4, and the fixing member 401 can slide along the axial direction of the supporting foot 4. The relative position of the fixing member 401 along the axial direction of the supporting foot 4 can be adjusted, and it can be suitable for fixing bottom covers 3 at different heights or for abutting and matching with positions at different heights on the same bottom cover 3.

[0065] For example, combined Figure 9 As shown, the fixing member 401 is connected to the supporting foot 4 through a sliding mechanism. In some embodiments, the sliding mechanism includes a sliding groove 402 provided on the supporting foot 4 and a slider slidably matched with the sliding groove 402. The fixing member 401 is fixedly connected to the slider, or one end of the slider extends out of the sliding groove 402 and protrudes on the outer circumferential surface of the supporting foot 4 to form the fixing member 401. The slide groove 402 is arranged along the axial direction of the supporting foot 4, and the slide groove 402 includes sliding sections 4022 and clamping sections 4021 alternately arranged along the axial direction of the supporting foot 4. The interior of the supporting foot 4 is hollow and can be deformed along both sides of the slide groove 402 under the action of external force. The width of the clamping section 4021 (the dimension along the axial direction perpendicular to the supporting foot 4) is equal to or slightly smaller than the width of the slider, the width of the sliding section 4022 is smaller than the width of the clamping section 4021, the inner wall of the sliding section 4022 smoothly transitions with the inner wall of the clamping section 4021, the length of the slider (the dimension along the axial direction of the supporting foot 4) is equal to the length of the clamping section 4021, when the slider is located in the clamping section 4021, the side wall of the clamping section 4021 abuts against the slider in the circumferential direction of the slider, fixing the slider; and under the action of external force, the slider can slide out of the clamping section 4021 along the axial direction of the supporting foot 4 and enter the next clamping section 4021 through the sliding section 4022. Therefore, the sliding mechanism can enable the fixing member 401 to slide in the axial direction of the supporting leg 4 and can be fixed relative to the supporting leg 4 when moving to a set position.

[0066] like Figure 10 As shown, the slide groove 402 can also be a linear groove, with multiple threaded holes spaced apart on the bottom wall of the slide groove 402, and a through hole provided on the slider 403, so that the slider 403 can slide along the slide groove 402. The third screw 404 passes through the through hole on the slider 403 and, by cooperating with different threaded holes at the bottom of the slide groove 402, locks the slider 403 at different positions within the slide groove 402, thereby adjusting the position of the slider 403. The fixing member 401 is fixedly connected to the slider 403, or one end of the slider 403 extends out of the slide groove 402 and protrudes onto the outer circumferential surface of the support leg 4 to form the fixing member 401.

[0067] Alternatively, in some other embodiments of the present application, the sliding mechanism includes a slide groove arranged along the axial direction of the supporting foot 4 and a slider cooperating with the slide groove, the slider is arranged on the fixing part 401, and the sliding mechanism also includes an elastic torsion spring, which is connected between the slider and the supporting foot 4. In a natural state, the elastic torsion spring squeezes the slider so that the slider always remains in the slide groove close to the pot body 1. Under the action of external force, the pressure of the elastic torsion spring can be overcome to move the slider away from the pot body 1. When the external force disappears, the slider is reset in the direction close to the pot body 1 under the action of the elastic torsion spring, thereby achieving the abutment and pressing of the fixing part 401 and the bottom cover 3.

[0068] In some embodiments of the present application, the fixing member 401 is retractable along the radial direction of the support leg 4. The length of the fixing member 401 can be adjusted, thereby adjusting the contact area between the fixing member 401 and the bottom cover 3. At the same time, when the upper surface of the fixing member 401 is grounded and fixed to the bottom surface of the flange 31, by adjusting the length of the support leg 4, the outer end surface of the support leg 4 (the end away from the support leg 4) can be made to contact the outer wall of the cover body 32, thereby stabilizing the position of the bottom cover 3 and preventing the bottom cover 3 from shifting in a direction parallel to the bottom surface of the pot body 1.

[0069] Specifically, the fixing member 401 is retractable along the radial direction of the supporting foot 4 and can slide along the axial direction of the supporting foot 4. The axial position and radial length of the fixing member 401 on the supporting foot 4 can be adjusted, thereby adapting to the locking of different positions of the bottom cover 3 at different heights.

[0070] In some embodiments of the present application, a buffer layer is provided on the upper surface of the fixing member 401, and the buffer layer is in contact with the bottom cover 3. Specifically, the buffer layer is made of a material with a certain elasticity, such as rubber, to avoid hard contact between the hard fixing member 401 and the bottom cover 3, thereby protecting the bottom cover 3.

[0071] like Figure 8 As shown, in the cooking pot provided in the embodiment of the present application, two fixing parts are used to lock the bottom cover, the first fixing part 401a abuts against the bottom surface of the flange, the second fixing part 401b abuts against the bottom surface of the cover body, and the second screw 7 passes through the second fixing part 401b and the second screw hole 7 and is fixed to the second screw column 102.

[0072] In some embodiments of the present application, the pot body 1 is further provided with a handle 9, a protective shell 8 and a pot cover 10. The handle 9 is arranged on both sides of the pot body 1, and the pot cover 10 covers the open upper end of the pot body. The protective shell 8 covers the position where the heating element 5 extends out of the cavity to avoid exposing the circuit and affecting the aesthetics and safety.

[0073] The embodiment of the present application increases the fixing points of the bottom cover 3 by adding fixing parts 401 to the supporting feet 4, so that the bottom cover 3 fits tightly with the pot body 1, solves the safety problem of scalding the user due to the deviation of the bottom cover 3 or the increase of the gap between the bottom cover 3 and the pot body 1 caused by the deformation of the pot body 1, and improves the safety performance of the cooking appliance; and by adding fixing parts 401 to the existing supporting feet 4, the fixing points of the bottom cover 3 are increased, and there is no need to add additional screws to fix the bottom cover 3 separately, and there is no need to change the structure of the pot body 1 (there is no need to add additional screw columns to the pot body 1 to add screws). Only the structure of the supporting feet 4 needs to be changed to achieve the fastening of the bottom cover 3, while ensuring structural stability and safety of use, and at the same time reducing costs as much as possible.

[0074] It should be noted that if Figure 11 As shown, the bottom cover 3 can also be fastened by adding screws to the flange 31. This method requires adding screws to the pot body 1 and drilling holes in the flange 31 of the bottom cover 3. The bottom cover 3 is then attached to the pot body 1 using screws. By directly fastening the bottom cover 3 to the pot body 1 with screws, the fixing point will not be susceptible to overheating and the bottom cover 3 will not be separated from the pot body 1.
