Description

Technical Field

[0001] This invention relates to the field of heat-insulating basin technology, specifically a heat-insulating basin and its preparation method. Background Technology

[0002] An insulated basin is a container with heat preservation function, mainly used to maintain the temperature of the contained items or liquids for a certain period of time and slow down their cooling rate. It is widely used in homes, restaurants, food delivery, outdoor activities, medical care, and laboratories.

[0003] Existing insulated basins typically use a water bath heating method and are equipped with a detachable lid to seal the insulation cavity. However, during the heating process, the generated water vapor condenses and adheres to the inner wall of the lid. When the user opens the lid, because the lid is completely separated from the basin, the condensed water easily drips down. To prevent water droplets from wetting the countertop or scalding themselves, users often need to quickly flip the lid over or wipe away the moisture on the inner wall before closing it again. This operation is cumbersome and has a low margin for error, and some condensed water still spills onto the outside of the insulated basin, affecting the convenience of use.

[0004] Therefore, it is urgent to optimize the existing lid structure of the heat-insulating basin to ensure sealing and heat preservation performance while solving the problem of condensation spillage, thereby improving the user experience. Summary of the Invention

[0037] The embodiments of the present invention will now be described in detail with reference to the accompanying drawings. The described embodiments are merely some, not all, of the embodiments of the present invention. All other embodiments obtained by those skilled in the art based on the embodiments of the present invention without inventive effort are within the scope of protection of the present invention.

[0038] Example 1 like Figure 1 , Figure 2 , Figure 3 The heat-insulating basin shown includes a shell 1, which has a pot body 7, a heating component 8 connected to the pot body 7, and a lid 3 covering the upper side of the pot body 7. The pot body 7 has a cavity 2, a shell opening 21 communicating with the cavity 2, and a support portion 4 supporting the lid 3. The lid 3 includes a first lid 31 hinged to one side of the shell 1 and a second lid 32 hinged to the first lid 31. The second lid 32 has an abutment portion 320 on the side away from the first lid 31. When the first lid 31 is rotated to switch to a folded state, the second lid 32 rotates to form an angle α or parallel with the first lid 31, and the abutment portion 320 abuts against the support portion 4, so that the shell opening 21 is exposed.

[0039] This invention improves safety and cleanliness by setting the cover to a segmented hinged structure consisting of a first cover and a second cover that are hinged together in sequence, and a folding support structure. The cover can be switched to a folded state without being completely removed, preventing condensation from spilling onto the countertop or the user.

[0040] Specifically, this invention features a folding structure consisting of a first cover and a second cover, with the first cover hinged to one side of the housing. When opening the cover, the user does not need to completely remove it and move it to the countertop; instead, they can open it by rotating it. Since the cover remains connected to the housing, with the abutting part abutting against the supporting part and positioned above the housing in the folded state, condensation adhering to the inner wall of the cover flows back into the cavity under gravity or is temporarily stored within the cover, thus preventing condensation from dripping onto the countertop or the user. This solves the technical problem of existing split-type covers easily wetting the countertop and scalding the user. Furthermore, the user only needs a simple folding motion to open and secure the cover, making it easy to operate and improving the user experience.

[0041] Specifically, by providing an abutment part on the second cover and a support part on the housing, when the cover is switched to the folded state, the first cover and the second cover form an angle α or are parallel. At this time, the abutment part and the support part abut against each other, so that the cover can be stably kept in the open state without the user holding it. It also prevents the cover from accidentally falling back and closing or overturning due to instability of the center of gravity, ensuring the effective exposure of the housing opening and making it convenient for the user to take out and put in items.

[0042] It should be noted that, based on the above-described overall design concept, when the abutting part and the supporting part of this embodiment abut together, a portion of the shell opening can be exposed, facilitating the operator's observation or quick closure after removing an object from the partial shell opening. Of course, all shell openings can also be exposed. It should be noted that the area of ​​the shell opening can correspond to the area of ​​the upper end of the cavity, or the area of ​​the shell opening can be unequal to the area of ​​the upper end of the cavity.

[0043] Optionally, in some embodiments, the shell opening is horizontally positioned. When the first cover and the second cover are horizontally positioned over the shell opening, the covers are in a closed state. When the first cover and the second cover form an angle α, the angle α is less than 180 degrees. A triangular support structure is formed between the first cover, the second cover, and the support portion.

[0044] Optionally, in some embodiments, the first cover and the second cover are arranged in parallel, and a rectangular support structure is formed between the first cover, the second cover, and the support portion.

[0045] Optionally, in some embodiments, the abutment portion is integrally formed at the end of the second cover.

[0046] Optionally, in some embodiments, the shell opening is inclined from bottom to top and from the second cover towards the first cover. When the first cover and the second cover are inclinedly covered on the shell opening, the cover is in a closed state. When the first cover and the second cover form an angle α, the angle α is less than 180 degrees.

[0047] Optionally, in some embodiments, the cross-section of the second cover is rectangular or rectangular with chamfers and rounded corners. When the longer side of the second cover abuts against the support portion, the extension distance of the shorter side of the second cover is greater than the extension distance of the shorter side of the first cover. When the second cover is folded, the second cover abuts against the support portion more easily.

[0048] In the above embodiment, when the extension distance of the short side of the second cover is equal to the extension distance of the first short side, the abutting part can be connected to the end of the short side of the second cover as a detachable component, so that the second cover abuts against the supporting part.

[0049] In the above embodiment, when the extension distance of the short side of the second cover is not equal to the extension distance of the first short side, and the abutting part can be connected to the end of the short side of the second cover as a detachable component, the angle α formed between the second cover and the first cover is less than 180 degrees.

[0050] Optionally, in some embodiments, by means of hinges, after the first cover and the second cover rotate relative to the housing, the first cover and the second cover are arranged parallel to each other and perpendicular to the plane of the housing opening. At this time, a rectangular support structure is formed between the first cover, the second cover, and the support portion. Of course, the abutment portion can be connected to the short end of the second cover as a detachable component, so that a rectangular support structure is formed between the first cover, the second cover, and the support portion.

[0051] like Figure 5 , Figure 9 , Figure 10 The heat-insulating basin shown has a first connecting part 311 and a first hinge 312 connected to the first connecting part 311 on the side of the first cover 31 near the second cover 32. The second cover 32 has a second connecting part 321 and a second hinge 322 connected to the second connecting part 321 on the side of the second cover 32 near the first cover 31. The first hinge 312 and the second hinge 322 are fixed by a first connecting shaft 51. When the abutting part 320 abuts against the supporting part 4, the upper surface of the first cover 31 and the upper surface of the second cover 32 both face outward. The first cover 31 and the second cover 32 are arranged in an inverted V shape, and the included angle α is between 0 and 180 degrees.

[0052] Furthermore, as a preferred embodiment of the present invention and not a limitation thereof, the first cover and the second cover are hinged by a first connecting shaft, so that the cover is arranged in an inverted V shape when open. At this time, the upper surfaces of the first cover and the second cover face outward, and the inner surfaces with condensation are arranged opposite each other and face downward or inward. The condensation adhering to the inner walls of the first cover and the second cover will naturally slide down the inner slope of the inverted V shape. In some embodiments, the condensation will drip directly into the cavity below. In other embodiments, the condensation will be confined to the inner side of the cover, thereby preventing water droplets from dripping onto the table surface and hiding the wet surface inside the inverted V-shaped structure, so that the user comes into contact with the dry outer surface of the cover.

[0053] Based on the above configuration, by utilizing the cooperation of the first and second hinges, combined with the abutting action of the abutting part and the supporting part, when the cover is in the folded state, the first cover acts as the hypotenuse, the second cover acts as the supporting side, and the shell acts as the bottom side, forming a stable triangular support structure in space. Compared with a simple single-piece flip cover or cantilever structure, the inverted V-shaped support method can more effectively distribute the gravity, so that the center of gravity of the cover falls within the shell area when it is opened, which has self-stability and is not easy to accidentally tip over or close due to touch.

[0054] As mentioned above, setting the included angle α between 0 and 180 degrees allows the first and second covers to adjust their folding range according to actual needs. When the cover is a segmented structure and inverted V-shape, it avoids the problems of excessively high center of gravity or excessively long lever arm after opening, which are common with traditional one-piece flip covers. When the included angle α is acute or obtuse, it can reduce the overall height of the cover when it extends vertically after opening.

[0055] Optionally, in some embodiments, the first and second covers are supported by an inverted V-shaped structure. When laid flat, they only need to allow for rotational clearance, achieving a near-seamless connection and reducing heat loss from gaps. If the first and second covers are supported by a rectangular structure, the wide axis in the middle will occupy space when laid flat, forming a dividing area and creating a larger gap, which is not conducive to sealing the covers.

[0056] Optionally, in some embodiments, the included angle α includes 5 degrees, 10 degrees, 15 degrees, 30 degrees, 45 degrees, 55 degrees, 60 degrees, 75 degrees, 90 degrees, 105 degrees, 120 degrees, 135 degrees, and 150 degrees.

[0057] like Figure 5 , Figure 9 , Figure 10The heat-insulating basin shown includes a first hinge member 312 comprising a first hinge plate 3121 disposed inside the first connecting portion 311 and a first hinge shaft 3122 connected to the first hinge plate 3121. The second hinge member 322 comprises a second hinge plate 3221 disposed inside the second connecting portion 321 and a second hinge shaft 3222 connected to the second hinge plate 3221. The first hinge shaft 3122 extends outward from the first connecting portion 311, and the second hinge shaft 3222 extends outward from the second connecting portion 321. The first hinge shaft 3122 and the second hinge shaft 3222 are connected by the first connecting shaft 51.

[0058] Furthermore, as a preferred embodiment of the present invention and not a limitation thereof, by respectively providing a first hinge plate and a second hinge plate on the inner sides of the first connecting portion and the second connecting portion, the first hinge plate and the second hinge plate serve as a force-bearing base. Compared to directly opening holes or setting a pivot in the cover material, the hinge plate can increase the contact area between the hinge structure and the cover. When the cover is frequently opened and closed or maintains an inverted V-shaped support state for a long time, it can disperse the torque and stress at the pivot, prevent cracking or damage at the cover connection due to stress concentration, and extend the service life of the equipment.

[0059] Based on the above configuration, the structure, which features a first hinge shaft and a second hinge shaft extending outwards and connected by a first connecting shaft, ensures that the axes of the first and second covers remain aligned during rotation, preventing loosening or wobbling. During the transition from a flat to a folded state, axial positioning ensures smoother formation of the inverted V-shaped structure, improving the user experience.

[0060] Furthermore, when the first and second covers form an inverted V-shaped structure, the hinge component is located at the connection between the first and second covers. The condensate adhesion surface on the inner wall of the cover has no protruding hinge component, forming a continuous and smooth guiding slope. This avoids the hinge component blocking the condensate backflow, ensuring that the condensate completely flows back to the inner cavity of the shell or is stored inside the cover, eliminating the risk of dripping. At the same time, by isolating the condensate from contact with the hinge component, it prevents the hinge plate and hinge shaft from rusting and corroding due to long-term contact with moisture, extending the service life of the hinge structure and reducing later maintenance costs.

[0061] like Figure 5 , Figure 9 , Figure 10The heat-insulating basin shown has a first hinge plate 3121 extending to the lower side of the first connecting portion 311, and a second hinge plate 3221 extending to the lower side of the second connecting portion 321. The first connecting portion 311 and the second connecting portion 321 are located between the first hinge plate 3121 and the second hinge plate 3221. The first hinge plate 3121 is connected to the first connecting portion 311 by a first fastener 61, and the second hinge plate 3221 is connected to the second connecting portion 321 by a second fastener 62.

[0062] Furthermore, as a preferred embodiment of the invention and not a limitation thereof, the hinge assembly is concealed by extending the first hinge plate and the second hinge plate to the lower side of the first connecting portion and the second connecting portion, i.e., the side of the cover facing into the cavity. Since the hinge plate assembly is partially located on the lower side of the cover, it structurally provides bottom shielding or limiting of the splicing gap between the first cover and the second cover, which helps to maintain the uniformity of the gap between the two covers. At the same time, it prevents foreign objects from directly getting stuck in the hinge mechanism through the gap with a short travel distance, thus ensuring the smoothness of the folding action.

[0063] As mentioned earlier, the first and second connecting parts are located between the first and second hinge plates and are secured with fasteners such as screws and rivets. When the cover is folded, the hinge plates provide support from below, distributing the torque and shear force generated during cover rotation. Compared to a simple side connection, the bottom extension with fasteners increases the contact area and holding force of the connection, preventing loosening, detachment, or breakage of plastic parts after long-term use.

[0064] like Figure 4 , Figure 6 The illustrated heat-insulating basin includes a first cover 31 with a third hinge plate 3131, a third hinge shaft 3132 connected to the third hinge plate 3131, and a third limiting part 3133 located on the third hinge plate 3131 or the third hinge shaft 3132. The housing 1 includes a fourth hinge plate 3141, a fourth hinge shaft 3142 connected to the fourth hinge plate 3141, and a third limiting part 3133 located on the fourth hinge plate 3141 or the fourth hinge shaft 3142. The fourth limiting part 3143 is connected to the third hinge shaft 3132 via the second connecting shaft 52. When the third limiting part 3133 and the fourth limiting part 3143 abut against each other, they are used to limit the rotation angle of the first cover 31. The third limiting part 3133 is provided with a third limiting part inclined surface 3134, and the fourth limiting part 3143 is provided with a fourth limiting part inclined surface 3144 that cooperates and contacts the third limiting part inclined surface 3134.

[0065] Furthermore, as a preferred embodiment of the present invention and not a limitation thereof, when the first cover rotates relative to the housing to the maximum opening angle, the inclined surface of the third limiting part and the inclined surface of the fourth limiting part fit together, thereby increasing the contact area during limiting, effectively dispersing the impact force and torque generated when the cover is opened to the position, avoiding plastic deformation, cracking or wear of the limiting part due to stress concentration, thereby improving the durability and reliability of the hinge structure.

[0066] In addition, the beveled design creates a damping or stopping sensation when the cover is opened to its maximum position, preventing users from applying excessive external force due to uncertainty about whether the cover is fully open, thus further protecting the connecting mechanism.

[0067] Specifically, the combination of the third hinge plate, the fourth hinge plate, the third hinge shaft, and the fourth hinge shaft, along with the second connecting shaft, ensures that the connection between the shell and the cover has good load-bearing capacity. It can not only support the weight of the cover itself, but also withstand the dynamic load during user operation, ensuring that it will not loosen during long-term use.

[0068] Example 2 Based on Example 1, Example 2 also has the following implementation method: like Figure 2 , Figure 9 , Figure 10 The heat-insulating basin shown has a second cover 32 connected to a handle 323, a first buffer 324 connected to the outside of the second connecting part 321, the first buffer 324 being used to connect to the outside of the first connecting part 311, and a second buffer 325 connected to the abutting part 320 abutting against the supporting part 4.

[0069] Optionally, in some embodiments, the second buffer may be an elastic material such as a silicone pad or a rubber strip.

[0070] Furthermore, as a preferred embodiment of the invention and not a limitation thereof, a second buffer is provided at the abutment portion of the second cover, so that when the cover is folded to form an inverted V-shaped support and abuts against the support portion of the shell, a flexible contact is formed at the contact interface. The second buffer increases the coefficient of friction between the abutment portion and the support portion, preventing the cover from slipping under force in the supported state and causing the overall support structure to collapse, thus ensuring the stability of the folding support structure. The second buffer eliminates rigid collision noise when the cover contacts the shell, and at the same time avoids scratches or wear on the surface of the support portion caused by long-term repeated contact.

[0071] Optionally, in some embodiments, the first buffer is a silicone strip or a waterproof soft rubber column. The first buffer is located outside the first connecting part and the second connecting part and serves as a transition between them. The first buffer covers the hinge gap between the first cover and the second cover, effectively preventing the heat in the cavity from escaping outward through the hinge gap, further improving the overall heat preservation effect of the heat preservation basin.

[0072] Optionally, in some embodiments, the flexible buffer structure shields the mechanical clearance of rotation, preventing users' fingers from being pinched by the hinge gaps during folding operations. It also serves to prevent dust and water damage, making the cover more integrated, neat and beautiful in appearance.

[0073] Specifically, when the cover is laid flat and closed, the first buffer can also play a tensioning or cushioning role to prevent loosening, abnormal noise, or collision and wear between the first cover and the second cover.

[0074] Specifically, a handle is provided on the second lid, positioned away from the third hinge axis, allowing users to easily lift or fold the lid with minimal force. When the insulated basin is in operation, the lid surface reaches a high temperature; the handle ensures a safe distance between the user's hands and the heated surface, avoiding the risk of burns from direct contact with the high-temperature surface.

[0075] like Figure 3 , Figure 9 , Figure 10 The heat-insulating basin shown includes a first buffer member 324 comprising a buffer member limiting part 3241 located inside the second connecting part 321, a buffer member abutting part 3242 located outside the second connecting part 321, and a buffer member connecting part 3243 connecting the buffer member limiting part 3241 and the buffer member abutting part 3242. The second connecting part 321 is provided with a second connecting part opening 3211 through which the buffer member abutting part 3242 and the buffer member connecting part 3243 pass. The first connecting part 311 is provided with a first connecting part opening 3111 that cooperates with the buffer member abutting part 3242. The first buffer member 324 is elastic, and the outer diameter of the buffer member limiting part 3241 is larger than the outer diameter of the second connecting part opening 3211.

[0076] Furthermore, as a preferred embodiment of the present invention and not a limitation thereof, by setting the outer diameter of the buffer member limiting portion to be larger than the outer diameter of the opening of the second connecting portion, self-locking and anti-detachment are achieved by utilizing the elastic properties of the first buffer member itself. During assembly, the first buffer member undergoes elastic deformation under force and passes through the opening of the second connecting portion. The buffer member limiting portion returns to its original shape under its own elastic force, thereby being locked inside the second connecting portion. This prevents the first buffer member from accidentally falling off during frequent opening and closing of the cover or during stress, ensuring the stability and durability of the connection.

[0077] Specifically, the installation can be completed by workers with a simple pulling motion, eliminating the need for complex tools and additional screws and glue for fixing, thus improving production efficiency. At the same time, by using a first buffer component instead of fasteners, the number of parts is reduced, lowering material and assembly costs.

[0078] Based on the above configuration, a flexible contact interface is formed between the first cover and the second cover by utilizing the elastic material of the first buffer and its outer buffer abutment. When the first cover and the second cover rotate relative to each other or close, the buffer abutment engages with the opening of the first connecting part, absorbing the impact energy generated by their collision. This eliminates the impact noise caused by the collision between the first cover and the second cover, achieving a silent effect. It also prevents wear or fatigue cracks at the cover connection point from long-term use, improving the product's durability and the quality of operation.

[0079] In addition, the elastic first buffer can compensate for the dimensional tolerances that occur between the first and second connecting parts during manufacturing and assembly, so that the connection of the cover remains tight and avoids loosening or shaking noise caused by excessive gaps.

[0080] Example 3 Based on Example 1, Example 3 also has the following implementation method: like Figure 2 , Figure 3 , Figure 7 The heat-insulating basin shown includes a support portion 4 comprising a first support portion 41 that abuts against the cover 3 and a connecting platform 42 located between the cavity 2 and the first support portion 41. The connecting platform 42 is inclined from the first support portion 41 toward the cavity 2 and from top to bottom. The abutting portion 320 is provided with an arc angle 3201, which abuts against the connecting platform 42. The upper end face of the first support portion 41 is horizontally arranged, and the first cover 31 and the second cover 32 are horizontally covered on the upper side of the first support portion 41.

[0081] Specifically, when the cover is laid flat, the first cover and the second cover will abut against the first support.

[0082] Optionally, in some embodiments, the second cover is rectangular, and when the cover is folded, the second cover abuts against the first support portion.

[0083] Furthermore, as a preferred embodiment of the invention and not a limitation thereof, a connecting platform is provided between the first support and the cavity, and this connecting platform is inclined downwards towards the cavity. When the cover is opened and abuts against the connecting platform, condensate collected on the edge and inner wall of the cover will drip directly onto or flow towards the inclined connecting platform. Utilizing gravity and the guiding effect of the inclined surface, water droplets falling onto the connecting platform will slide into the cavity without overflowing outwards to the first support or the outside of the basin. Even if a small amount of water droplets do not slide off the inverted V-shaped surface of the cover, they can be safely collected at the support contact point.

[0084] Based on the above configuration, the arc-shaped corner of the contact part is used to engage with the inclined connecting platform of the shell. During the process of the cover rotating from a closed state to a folded support state, the arc-shaped corner contacts the inclined surface. Compared with the contact of sharp corners, this effectively reduces the rotational friction resistance, making the opening process smoother and more comfortable, and avoiding jamming.

[0085] As mentioned earlier, when the cover is fully opened to form an inverted V-shaped support, the curved corner engages with the inclined connecting platform. Due to the inward tilt of the connecting platform, the cover tends to slide inward under the influence of gravity, thus being more tightly connected to the support position. By utilizing the self-locking effect of the component of gravity, the cover is less likely to slip off in the supported state, and its resistance to vibration and accidental impact is stronger.

[0086] Specifically, the upper surface of the first support is horizontally positioned. When the first and second covers are horizontally closed, their edges fit smoothly against the horizontal first support, forming a stable planar sealing structure that prevents heat leakage and ensures insulation. The horizontal support surface provides uniform support force. When the user places small, light items on the closed cover or when the cover is subjected to external pressure, the force can be evenly transmitted to the shell, preventing the cover from deforming or falling into the cavity.

[0087] like Figure 7 , Figure 9 , Figure 10 The heat-insulating basin shown has a cover 3 comprising a reinforcing portion 33 disposed in the first cover 31 and / or the second cover 32, and an extension portion 34 connected to the reinforcing portion 33. The reinforcing portion 33 can abut against the first supporting portion 41. The end of the extension portion 34 is located on the upper side of the connecting platform 42. The reinforcing portion 33 is horizontally disposed on the inner side of the first cover 31 and / or the second cover 32. The extension portion 34 is provided with a guide surface 341. When the cover 3 is in the closed state, the guide surface 341 is used to guide the medium to the connecting platform 42.

[0088] Furthermore, as a preferred embodiment of the invention and not a limitation thereof, an extension is provided on the reinforcing portion, with its end suspended above the connecting platform. When the cover is closed, water droplets condensing on the inner wall of the cover will flow along the inner wall to the extension. Using the guide surface on the extension, the water droplets are forced to change their flow path, passing over the first support portion and dripping directly onto or being channeled onto the inclined connecting platform. This prevents water droplets from laterally penetrating along the edge of the cover into the contact gap between the first support portion and the reinforcing portion using surface tension or capillary action, eliminating the risk of overflow caused by condensate accumulation at the seal, and reducing the likelihood of water droplets dripping outwards from the surface of the first support portion after the cover is opened.

[0089] Specifically, a horizontal reinforcing section is provided on the inner side of the first cover and / or the second cover, and abuts against the first supporting section of the shell. The reinforcing section acts as a reinforcing rib, improving the structural rigidity and deformation resistance of the cover edge, preventing the cover from warping due to heat or stress, and ensuring that the cover edge remains flat.

[0090] Specifically, the reinforcing part and the horizontal first support part form a wide planar contact, providing uniform support reaction force, ensuring the stability when the cover is closed, and also forming a physical barrier. Together with the guiding effect of the extension part, it improves the sealing and heat preservation performance of the whole machine.

[0091] Optionally, in some embodiments, the guide surface is a sloped surface or a circular arc surface.

[0092] Based on the above configuration, the guide surface allows the medium to quickly detach from the cover surface under gravity. Compared to traditional right-angled edges, the guide surface reduces the adhesion of water droplets, accelerates the dripping process of condensate onto the connecting platform, prevents water droplets from lingering on the cover edge for extended periods, and maintains the cleanliness of the cover when it is opened.

[0093] Optionally, in some embodiments, the reinforcing parts are disposed on both sides of the bottom of the first cover and both sides of the bottom of the second cover. When the cover is folded, the reinforcing parts can guide the condensate to the lower side where there is no reinforcing part blocking it. That is, some of the condensate is transferred to the connecting platform in the direction of the abutment part, and some of the condensate is transferred to the connecting platform in the direction of the first cover near the third hinge axis.

[0094] Optionally, in some embodiments, the reinforcing portions are disposed on both sides of the bottom of the first cover and on the side of the bottom of the first cover away from the abutment portion. Additionally, the reinforcing portions are disposed on both sides of the bottom of the second cover and on the side of the bottom of the second cover near the abutment portion. Specifically, when the cover is folded, the reinforcing portions can store condensate, while ensuring that, in the closed state, the condensate is transferred to the connecting platform through the guide surface of the extension portion, thus improving the sealing performance in the closed state.

[0095] Alternatively, in some embodiments, such as Figure 7 As shown, the second buffer can cover the extension and the abutment.

[0096] Example 4 Based on Example 1, Example 4 also has the following implementation method: like Figure 19 and Figure 20 As shown, the method for preparing the heat-insulating basin includes the heat-insulating basin as described above, a structural reinforcement 17 connected to the bottom of the shell 1, a base plate 18 connected to the structural reinforcement 17, a fixing plate 19 that limits the shell 1, and a circuit assembly 20. The preparation method includes: S1. Cut a long strip of metal block and bend the metal block until the two short sides of the metal block are facing each other to obtain a shell 1 with a polygonal cross-section; S2. Fix the two opposite short sides of the housing 1 with the fixing plate 19, forming a gap 26 between the two opposite short sides; S3. The edge of the pot body 7 is connected to the upper edge of the shell 1 by welding. The lower side of the shell 1 is welded to the structural reinforcement 17. The sealant is poured into the gap. S4. Install the heating component 8 onto the pot body 7, connect the circuit component 20 to the heating component 8, connect the bottom plate 18 to the reinforcing structural component 17, and install the cover 3 onto the shell 1 to obtain the heat preservation pot.

[0097] In existing technologies, the shell is typically manufactured using either stamping or modular welding. For stamping, when the sheet metal is cut into round or square blanks suitable for stamping, a large amount of scrap material is generated at the four corners. This scrap is difficult to reuse, resulting in a high waste rate. Modular welding requires disassembling the shell into multiple components such as side panels and a bottom plate, cutting each component separately, and then welding them together, resulting in a large number of welds and processes.

[0098] If a polygon is made using a stamping process, the material's fluidity is extremely important. To prevent tearing, larger blanks are often needed, leading to a further increase in scrap rate. The bending process of this invention is suitable for polygons, hardly changing the metal thickness, ensuring uniform wall thickness throughout the shell, and avoiding the localized thinning and stress concentration problems common in stretching processes. It only requires adding a few bending points to the strip, without increasing material consumption.

[0099] Specifically, the existing pot body is detachably connected to the upper edge of the shell. While this design makes it convenient to remove the pot body for cleaning, moisture can easily seep into the electrical components through the gap between the shell and the pot body. Furthermore, the separation of the heating element from the pot body means that the temperature sensing element cannot make precise contact with the pot body, which can lead to inaccurate temperature control of the insulated pot. In addition, frequent installation and removal of the pot body from the shell can damage the heating element and temperature sensing element during the movement of the pot body.

[0100] Optionally, in some embodiments, the shell cross-section can be a regular polygon, or an irregular or non-standard polygon.

[0101] Alternatively, in some embodiments, the shell cross-section is bent to have rounded corners.

[0102] This invention reduces the entry of water vapor and foreign objects into the shell by welding the pot body to the shell, thereby extending the overall service life. In addition, the heating component is fixedly connected to the pot body, and the temperature detection element 25 extends directly into the cavity, thereby ensuring accurate temperature control of the heat preservation pot.

[0103] Additionally, in step S1, a first opening 101 for the panel to extend into and a second opening 102 for the plug to extend into are punched.

[0104] Specifically, in this embodiment, there are two heating components, with a temperature detection element 25 located between the two heating components. The upper side of the heating components is provided with a shelf 22 with multiple openings, which can support objects. The circuit components include circuit components 23 and a fan 24. The bottom plate is provided with an air outlet 181 for the fan to blow air, and an air inlet 182 for external airflow to enter the inner side of the bottom plate. The fan is used to cool the circuit components.

[0105] Specifically, by setting gaps, errors can be reduced when cutting or bending the sheet material. The structural reinforcement serves as the flange of the shell, ensuring overall strength and acting as a connection point for the base plate.

[0106] Specifically, in this embodiment, the shell is bent into a rectangular shape, and the fixing plate is connected between the two opposite short sides and located on the outside of the shell, which can cover the gaps and serve an aesthetic purpose. The sealant can reduce the amount of moisture that can enter the interior of the shell through the gaps.

[0107] Specifically, a fixing plate is installed on the outside of the shell, its width spanning two opposite short sides, and is connected between the two opposite short sides by screws, extending along the height direction of the shell to cover the gap. A structural reinforcement is welded in a horizontal ring shape to the bottom of the shell, and a base plate is connected to the structural reinforcement by screws.

[0108] Alternatively, in some embodiments, the sealant may be glass glue or epoxy resin sealant.

[0109] In existing technologies, the seams of metal casings typically require complete welding and polishing to achieve a seamless appearance. The casing of this invention utilizes a fixing plate for positioning and is sealed with adhesive. This significantly reduces the requirements for welding precision and even eliminates the need for welding and polishing the sides of the casing, simplifying the process.

[0110] Specifically, there is a certain space between the outer side of the pot body and the inner side of the shell, which allows operators to install screws or other parts.

[0111] Example 5 Example 5, based on Example 4, also has the following implementation method: like Figure 11 , Figure 12 , Figure 13 , Figure 14 , Figure 15 , Figure 16 The heat-insulating basin shown has a housing 1 with a panel 11, a panel opening 110 on the panel 11, a cover plate 12 covering the panel opening 110, and a disassembly device for separating the panel 11 and the cover plate 12. The disassembly device includes a handle 9, one end of which is connected to a first extension 91 extending in a first direction and an insertion end 92 located on the first extension 91 and extending in the first direction. A positioning component 93 is provided on one side of the first extension 91. The positioning component 93 has a positioning part 931 extending in the first direction. The positioning part 931 is used for alignment or abutment against the outside of the panel 11. The panel 11 has a panel first connector 111, and the cover plate 12 has a cover plate first connector 121 that cooperates and is fixed with the panel first connector 111. The panel 11 and / or the cover plate 12 have a connection hole 13 for the insertion end 92 to extend into.

[0112] Because the pot body is welded to the shell, it is quite inconvenient to disassemble the touch panel. If replacement or maintenance is required, the water in the pot body must be poured out first, and the bottom plate must be flipped over to disassemble the entire device, which is extremely inconvenient to operate.

[0113] To address this issue, existing technologies typically incorporate an internal mounting cavity within the device, enclosed by a cover plate. To improve installation efficiency, the cover plate and cavity are often connected using snap-fit ​​mechanisms. However, to avoid touch-sensitive areas or circuitry and to prevent moisture and impurities from entering the mounting cavity, the snap-fit ​​mechanisms are usually located at the edges of the cover plate and the cavity, and are tightly secured, requiring tools for disassembly. Using a standard screwdriver requires the operator to constantly adjust their angle to find gaps and strictly control the prying depth. If the screwdriver is inserted too deeply, it can easily damage the internal circuitry and shorten the device's lifespan.

[0114] This invention provides a positioning component with a positioning part on one side of the first extension. During disassembly, the positioning part can be directly aligned with or abutted against the outside of the external device to form a stable support point, eliminating the need for the operator to repeatedly adjust the viewing angle to find the buckle gap. This simplifies the operation steps and improves the ease of operation. The limiting function of the positioning part of this invention can help to calibrate the insertion depth of the insertion end, avoiding accidental contact or damage to sensitive components such as internal circuits and touch panels due to excessive prying, thus improving maintenance safety.

[0115] Specifically, the cover of this application is a touch panel, which can drive the heat preservation basin to work or stop by pressing or clicking.

[0116] Optionally, in some embodiments, the external device can be a cover or a housing. By setting a matching structure between the positioning component and the insertion end, the positioning part abuts against the outer structure of the external device, such as a groove or a frame, which can provide a reference and physical limit for the insertion end. The positioning part limits the maximum depth of the insertion end into the installation cavity, thereby avoiding situations where the operator uses too much force or is limited by the viewing angle or lack of experience, resulting in the tool being inserted too deeply, touching and damaging the internal touch panel or circuit integration structure, thus improving the safety of the disassembly process.

[0117] Specifically, in this embodiment, by utilizing the abutting action of the positioning part on the outside of the external device, the operator does not need to use traditional general-purpose tools such as screwdrivers, repeatedly adjust the viewing angle to find gaps, or probe to confirm the point of force. During operation, simply place the positioning part against the surface of the external device, and the insertion end will automatically align with the disassembly gap or the snap-fit ​​position, achieving rapid positioning, reducing the skill requirements for the operator, simplifying the disassembly steps, and improving maintenance efficiency.

[0118] This invention uses a handle that moves away from the external device to separate the detachable structure of the insertion end, transforming a complex prying action into a simple pulling or lever action. The positioning component also acts as a fulcrum or guide during this process, ensuring that the applied force is more perpendicular or conforms to the latch disengagement path. This avoids the risk of cover edge deformation or latch breakage due to prying angle deviation, thus extending the service life of the external device.

[0119] Optionally, in some embodiments, during disassembly, the positioning part abuts against the outside of the device housing as a fulcrum, the insertion end as a force-bearing point, and the handle as a lever arm, forming a stable triangle or lever structure, thereby making the separation action more effortless and avoiding the slippage phenomenon caused by the instability of single-point contact in traditional tools, making the operation process more stable and reliable.

[0120] Optionally, in some embodiments, the positioning part moves vertically toward the edge of the cover, moving while aligning, so that the insertion end is inserted vertically into the inside of the mounting cavity.

[0121] Optionally, in some embodiments, after the inclined positioning part partially abuts against the outer side of the cover frame, the positioning part acts as a fulcrum, and by rotating the handle, the insertion end rotates from the inclined direction to the inner side of the mounting cavity that extends vertically.

[0122] Optionally, in some embodiments, the detachable structure may be a flexible snap-fit ​​and slot-fit structure, a magnetic connection structure, a mortise and tenon connection structure, a column-slot connection structure, an interference fit, or other connection methods.

[0123] Alternatively, in some embodiments, the insertion end moves directly away from the device, causing the cover to separate by pulling.

[0124] Optionally, in some embodiments, the insertion end first pushes the cover upward or downward to separate the cover's latch from the slot, and then the insertion end moves away from the device, separating the cover by pushing and then pulling.

[0125] like Figure 11 , Figure 12 , Figure 13 As shown, the thickness of the insertion end 92 gradually narrows along the first direction, the cross-section of the insertion end 92 is trapezoidal, and the side of the insertion end 92 near the handle 9 is provided with an inclined surface.

[0126] Furthermore, as a preferred embodiment of the invention and not a limitation thereof, the thickness of the insertion end gradually narrows along the first direction, forming a wedge-shaped structure at the front end. At the start of the disassembly operation, the thinner tip can cut into the assembly gap between the cover plate and the mounting cavity, overcoming the disadvantages of conventional tools being difficult to insert due to their thicker ends or requiring forced insertion. The trapezoidal tapering sides reduce the contact area between the disassembly device and the sidewalls of the external device gap, reducing frictional resistance. Simultaneously, this shape better adapts to assembly gaps with chamfers or rounded corners, preventing chipping or scratches at the gap edges due to forced insertion.

[0127] Specifically, as the insertion end extends into the external device, the inclined surface acts as a guide and expander, smoothly converting the thrust of the disassembly device along the first direction into a separation force perpendicular to the contact surface, causing the buckle assembly to gradually separate from the slot. This gradual force application avoids stress concentration caused by instantaneous explosive force on the buckle, thereby preventing buckle breakage and achieving smooth and controllable disassembly.

[0128] As mentioned above, the cross-section of the insertion end is trapezoidal. Compared with the traditional rectangular cross-section, the wider side of the trapezoid ensures that the insertion end has sufficient bending section modulus when pried or pulled, making it less prone to bending deformation or breakage, thus extending the service life of the disassembly device.

[0129] Furthermore, as a preferred embodiment of the invention and not a limitation thereof, a guide channel is provided for the insertion end of the disassembly device by pre-setting connection holes on the panel and / or cover plate. During operation, the insertion end can directly and accurately extend into the locking position of the first connector of the panel and the first connector of the cover plate through the connection holes, eliminating the blindness of searching for the buckle position along the gap of the cover plate in the traditional disassembly method, and improving the accuracy and success rate of disassembly.

[0130] Specifically, the design utilizes a connecting hole for the insertion end to extend into, preventing hard friction or pressure between the disassembly device and the edge of the panel or cover. This solves the problem of paint chipping, deformation, pry marks, or enlarged gaps on the cover edges that are easily caused during disassembly. Using the dedicated disassembly device in conjunction with the connecting hole, the tightly connected structure can be separated through a simple plugging and unplugging action.

[0131] Optionally, in some embodiments, when the panel has a connection hole, the insertion end is pulled away from the device to detach the cover from the panel.

[0132] Optionally, in some embodiments, when the cover plate is provided with a connection hole, the insertion end first pushes the cover plate upward, and then pulls the cover plate away from the device to detach it from the panel.

[0133] Example 6 Based on Example 5, Example 6 also has the following implementation method: like Figure 11 , Figure 12 , Figure 13 The heat-insulating basin shown includes a positioning component 93 comprising a second extension 932 located on the side of the first extension 91. The positioning part 931 is located on the second extension 932, which extends along a second direction. The first direction is perpendicular to the second direction. At least two insertion ends 92 are provided. The centerline between the two insertion ends 92 located at both ends of the first extension 91 coincides with the centerline of the handle 9. An angle β is formed between the handle 9 and the first extension 91, and the angle β is between 0 and 120 degrees.

[0134] Furthermore, as a preferred embodiment of the invention and not a limitation thereof, by providing a second extension portion extending along the second direction and perpendicular to the first direction, a stepped limiting structure is formed in space between the positioning component and the insertion end. During disassembly, when the insertion end extends in along the first direction, the vertically provided second extension portion can act as a rigid stop surface, flattening or abutting against the surface of the external device over a large area.

[0135] Compared to point contact or line contact positioning methods, utilizing the second extension portion extending along the second direction to support the positioning portion increases the lever arm span of the disassembly device or the contact area with the external device surface, thereby dispersing the stress at the contact point and preventing damage to the equipment casing due to concentrated force. Simultaneously, the vertically extending structure restricts the lateral swaying or tilting of the handle during operation, ensuring that the disassembly force is stably transmitted along the predetermined separation path, avoiding accidental damage caused by slippage of the disassembly device.

[0136] It should be noted that, based on the above-mentioned overall design concept, the second extension extending along the second direction ensures that the positioning part does not occupy or obstruct the view of the disassembly gap and its edges, while also providing sufficient space for deformation or displacement of the insertion end. Furthermore, the side-extending structure facilitates adaptation to external devices of different widths or edge shapes, allowing the disassembly device to maintain good fit and applicability even in compact or irregularly shaped installation environments.

[0137] Furthermore, as a preferred embodiment of the present invention and not a limitation thereof, during the disassembly process, multiple insertion ends can simultaneously act on multiple latching nodes or force-bearing parts of the external device, realizing multi-point synchronous unlocking, improving disassembly efficiency, and effectively dispersing the stress at the force application points, avoiding buckle breakage or local deformation of the cover plate due to excessive force at a single point, thus enhancing the stability of the disassembly process.

[0138] Because the centerline between the two insertion ends coincides with the centerline of the handle, the disassembly device forms a symmetrical mechanical structure. When the operator holds the handle and applies pulling or pushing force, the direction of the force and the resistance center of the working end are always on the same axis. The coaxial force transmission design eliminates the lateral torque caused by asymmetrical force, preventing the disassembly device from tilting or slipping when under force.

[0139] The 0-120 degree included angle β formed between the handle and the first extension causes the handle to tilt up or deviate from the surface plane of the external device. The angle setting can convert the horizontal pulling force of the hand into a vertical separation force on the buckle, reducing operator fatigue.

[0140] Optionally, in some embodiments, the included angle β is 15 degrees, which is suitable for the operator to operate with a reverse hand.

[0141] Optionally, in some embodiments, the included angle β is 30 degrees.

[0142] Optionally, in some embodiments, the included angle β is 45 degrees.

[0143] Preferably, in some embodiments, the included angle β is 60 degrees, which is suitable for the operator to use either a forehand or backhand grip.

[0144] Optionally, in some embodiments, the included angle β is 75 degrees.

[0145] Optionally, in some embodiments, the included angle β is 90 degrees, which is suitable for the operator to operate with their forehand.

[0146] The insertion end 92 has a first inclined surface 921 at both ends along the length direction of the first extension 91, and a second inclined surface 922 at both ends along its thickness direction. The cross-section of the insertion end 92 is an isosceles trapezoid.

[0147] Furthermore, as a preferred embodiment of the invention and not a limitation thereof, by providing a first inclined surface at both ends along the length direction of the insertion end and a second inclined surface at both ends along the thickness direction, a bidirectional wedge-shaped guide structure is formed at the front end of the insertion end. The first and second inclined surfaces replace the traditional right-angled edge, eliminating the rigid sharp angles on the periphery of the insertion end. During disassembly, when the disassembly device scrapes or squeezes against the edge of the gap between itself and the external device, the first and second inclined surfaces can change the contact form from cutting contact to sliding contact, reducing the coefficient of friction and preventing the disassembly device from causing scratches, chipping, or paint peeling to the device casing.

[0148] Specifically, the first inclined surface allows the insertion end to automatically slide into the center of the disassembly gap when there is a left or right deviation in the initial alignment of the disassembly device, thus having a self-alignment and correction function.

[0149] Specifically, the second bevel reduces the thickness of the insertion tip, enabling it to overcome the resistance caused by the tight fit and smoothly cut into the deep joint between the cover plate and the housing, thereby reducing the requirements for the operator's positioning accuracy and achieving fast and smooth operation.

[0150] Compared to asymmetrical structures, the isosceles trapezoidal cross-section of the insertion end of this invention ensures uniform internal stress distribution when the disassembly device is subjected to compression or prying force on both sides, avoiding localized fractures or torsional deformations caused by stress concentration. The wider root of the isosceles trapezoid gives the insertion end a good flexural section modulus, ensuring that the disassembly device maintains structural rigidity as the thickness gradually decreases, enabling it to withstand the high-intensity loads brought about by disassembly and extending its service life.

[0151] like Figure 11 , Figure 12 , Figure 13The heat-insulating basin shown has an uppermost height of the second extension 932 that is less than the lowermost height of the insertion end 92, an uppermost height of the insertion end 92 that is greater than the uppermost height of the positioning part 931, and a lowermost height of the insertion end 92 that is less than the uppermost height of the positioning part 931. The positioning part 931 is located at the end of the second extension 932 away from the insertion end 92. There are two insertion ends 92 located at both ends of the first extension 91. The extension distance of the second extension 932 is less than the distance between the two insertion ends 92.

[0152] Furthermore, as a preferred embodiment of the invention and not a limitation thereof, a distance difference is formed between the second extension and the insertion end, creating a structural height difference and clearance space between the insertion end and the positioning part in the height direction, thereby adapting to the edge wall thickness of the external device. During operation, the positioning part fits against the outer surface of the device, while the insertion end can extend beyond the thickness of the cover plate to the snap-fit ​​position inside, solving the problem of difficulty in positioning straight-handled tools due to the thickness of the cover plate and ensuring effective transmission of disassembly force.

[0153] Optionally, in some embodiments, if the uppermost height of the second extension is flush with the lowermost height of the insertion end, when the connection between the positioning part and the second extension does not match the shape of the cover frame, the positioning part does not fit the outer frame of the cover, which may cause the positioning part to slip, and the end of the insertion end or the first extension cannot abut against the outer frame of the cover.

[0154] Optionally, in some embodiments, the uppermost height of the insertion end is set to be greater than the uppermost height of the positioning part. The insertion end has a larger cross-sectional height or a reinforcing structure at the connection point. This not only ensures that the insertion end has sufficient bending strength when subjected to a large disassembly torque, preventing the front end of the disassembly device from breaking or deforming, but also forms a stable mechanical fulcrum conversion zone at the connection point. This helps to efficiently convert the horizontal tension of the handle into the separation force of the latch, thereby improving the durability and force transmission efficiency of the disassembly device.

[0155] Optionally, in some embodiments, the setting that the height of the lowest side of the insertion end is less than the height of the highest side of the positioning part can ensure that the positioning part first abuts against the outer edge of the cover, and then the insertion end extends into the installation cavity by moving the handle in the vertical direction or rotating the handle around the positioning part as a fulcrum.

[0156] The positioning part 931 has an abutment end 9311 extending in the first direction on the side near the insertion end 92.

[0157] Furthermore, as a preferred embodiment of the present invention and not a limitation thereof, by limiting the extension distance of the second extension to be less than the distance between the two insertion ends, and the lateral support span formed by the two insertion ends to be greater than the longitudinal distance of the positioning part extending outward, when the base width is greater than the cantilever length, the center of gravity during force application always falls within the stable support area formed by the two insertion ends and the positioning part, thereby improving the anti-tilting ability of the disassembly device during operation and preventing the disassembly device from swaying left and right or tipping over due to excessively long lever arm or excessively narrow base.

[0158] Specifically, the positioning part has an abutment extending in the first direction on the side near the insertion end, which can fit more closely to the edge step of the surface of the external device, forming a stop and guide function, eliminating the misalignment during positioning, and preventing the positioning part from slipping during the application of force, thus ensuring the accuracy of the disassembly operation.

[0159] Based on the above configuration, the shorter second extension shortens the force transmission path, making the overall structure more compact, portable, and easy to store. When the operator presses or pulls the handle, it reduces the ineffective bending moment caused by the excessively long cantilever, allowing the applied force to be transmitted more directly and efficiently to the insertion end for separating the latch, thus improving the mechanical transmission efficiency of the disassembly device.

[0160] like Figure 5 , Figure 6 , Figure 7 , Figure 8 The quick-release structure shown has a panel 11 with a protruding outer edge 112 extending towards the cover plate 12. A first panel connector 111 is disposed on the outside of the outer edge 112. The cover plate 12 has an outer edge 122 extending towards the panel 11. A first cover plate connector 121 is disposed on the inside of the outer edge 122. The connecting hole 13 includes a first connecting hole 131 penetrating the outer edge 112 and a second connecting hole 132 penetrating the outer edge 122. The first connecting hole 131 and the second connecting hole 132 communicate with each other. The outer edge 112 protrudes outward from the outer side of the housing 1. The panel 11 is fixedly connected to the housing 1 by fasteners 14.

[0161] Optionally, in some embodiments, when the panel has a connection hole, the insertion end pulls the cover away from the device to detach it from the panel. When the insertion end of the disassembly device extends into the panel, it can directly pass through the double wall thickness of the cover and the panel, ensuring the alignment of the disassembly device with the internal locking structure. The unlocking action occurs inside the outer wall thickness, and the disassembly device does not need to extend into the device cavity, thereby physically isolating the disassembly device from touching internal circuit boards or precision components such as batteries, achieving safe disassembly.

[0162] Furthermore, by utilizing the overlapping structure of the outer edges of the panel and the cover plate, the first connector of the panel and the first connector of the cover plate are hidden in the interlayer between the two outer edges. This allows the two outer edges to share the stress when the cover plate and the panel are subjected to lateral impact, improving the overall rigidity and impact resistance of the housing assembly. The staggered outer edges form a sealed structure, effectively blocking the path of external dust or moisture directly into the mounting cavity, thus improving the dustproof and waterproof performance of the entire unit.

[0163] Based on the above configuration, the panel is securely fixed to the housing using fasteners such as screws and bolts, with the outer edge of the panel protruding beyond the housing. During disassembly, the panel can effectively withstand the reaction force applied by the disassembly device. The force point during disassembly is concentrated on the replaceable panel without affecting the housing surface. Even if wear occurs around the connection holes due to improper operation, only the panel or cover needs to be replaced, reducing the long-term maintenance costs and repair risks of the equipment.

[0164] The above examples are merely illustrative of the technical content of the present invention to facilitate easier understanding by the reader, but do not imply that the implementation of the present invention is limited to these examples. Any technical extensions or re-creations made based on the present invention are protected by the present invention. The scope of protection of the present invention is defined by the claims.
