Description

Technical Field

[0001] This utility model relates to the field of kitchenware technology, and in particular to a crack-resistant casserole with a biomimetic honeycomb structure. Background Technology

[0002] Earthenware pots, as traditional cooking utensils, are widely used due to their excellent heat retention properties. However, the inherent brittleness and high coefficient of thermal expansion of the ceramic substrate result in insufficient thermal shock resistance. Industry test data shows that traditional earthenware pots are prone to cracking during thermal shock cycling tests, severely limiting their application in the high-heat, rapid-cooking scenarios of modern kitchens. Existing technologies generally improve the crack resistance of earthenware pots by increasing the pot body thickness and adding carbon fiber or zirconia-reinforced ceramic to the ceramic substrate. However, in practical applications, while increasing the pot body thickness improves mechanical strength, it leads to a significant increase in weight, and the increased heat capacity leads to increased preheating energy consumption. Adding carbon fiber or zirconia-reinforced ceramic to the ceramic substrate can significantly improve thermal shock resistance, but it greatly increases raw material costs, and uneven fiber distribution can easily lead to localized stress concentration, further exacerbating the cracking problem. Furthermore, the pore size of traditional earthenware pots cannot be adjusted to suit different cooking needs, resulting in poor steam release or excessive steam loss, affecting cooking results. Therefore, we propose a crack-resistant earthenware pot with a biomimetic honeycomb structure. Utility Model Content

[0003] To address the aforementioned problems, this invention provides a crack-resistant casserole with a biomimetic honeycomb structure.

[0004] To achieve the above objectives, this utility model provides the following technical solution:

[0005] Design a crack-resistant casserole with a biomimetic honeycomb structure, including a pot body. The pot body includes an inner liner, a biomimetic honeycomb layer, and a protective layer, from the inside out. The top of the pot body has a pot opening, and a pot lid is provided on the pot opening. An annular strip that cooperates with the pot lid is fixed on the inner wall of the pot opening. A pot lid handle is installed on the top of the pot lid. An adjustable vent structure is provided on the side of the pot lid handle. The adjustable vent structure includes a venting cylinder that communicates with the inside of the pot lid. An exhaust pipe is inserted into the venting cylinder. An exhaust hole with an inverted cone-shaped bottom is opened in the exhaust hole. A plug that can move up and down is movably connected to the exhaust hole. A heat-insulating cover that seals the top of the exhaust pipe is fixed on the top of the plug.

[0006] In the above solution, the pot lid handle includes a connecting block fixed to the pot lid, a gripping block is fixed to the top of the connecting block, and notches are evenly provided around the gripping block.

[0007] In the above scheme, the connecting block is provided with a socket in the inner radial direction, and a side insertion groove communicating with the socket is provided on one side of the connecting block.

[0008] In the above solution, the ventilation cylinder is provided with locking blocks on both sides, and a silicone sleeve is fixed to the top of the exhaust cylinder. The silicone sleeve has a locking groove that fits with the locking blocks.

[0009] In the above scheme, a threaded sleeve connected to the plug is fixed to the inner wall of the top of the vent hole. A blocking ring is provided below the threaded sleeve and fitted on the outside of the plug. A through hole one is opened on the blocking ring, and a through hole two is opened inside the threaded sleeve.

[0010] In the above solution, a handle is fixed on one side of the pot body, and a placement groove is provided on the top of the handle to fit the edge of the pot lid.

[0011] In the above scheme, a second handle is fixed on one side of the pot body, a storage sleeve is movably fitted on the second handle, a pair of connecting rods are fixed on the storage sleeve, and a limit block is fixed at the top of the connecting rod.

[0012] The advantages and beneficial effects of this utility model are as follows: By setting a biomimetic honeycomb layer and utilizing the biomimetic principle of honeycomb, the pressure of the pot body under thermal expansion is evenly distributed. Compared with the prior art, this significantly reduces the risk of the pot body cracking due to sudden temperature changes, promotes the dispersion of thermal stress, and thus enhances the impact resistance of the pot body, effectively preventing cracking. Furthermore, by setting an adjustable vent structure and using a plug to move it up and down, the opening and closing degree of the vent can be adjusted. Compared with the prior art, this allows for flexible switching from slow venting through micropores to fast venting with full opening, suitable for stewing and cooking. To meet different cooking needs such as reducing sauce, it achieves a multi-stage steam release effect. By setting up a threaded sleeve, a barrier ring, and through holes one and two, and utilizing the staggered distribution of through holes one and two, an airflow resistance gradient is formed. This not only avoids concentrated steam jets but also prevents backflow of external impurities, achieving a multi-stage steam buffering and anti-backflow effect. By setting up a silicone sleeve, a locking block, and a locking groove, and adopting a plug-in structure, users can disassemble and clean the relevant components of the adjustable vent structure by hand. This not only allows for quick disassembly and assembly but also achieves a sealing and leak-proof effect, making it more convenient to use. Attached Figure Description

[0021] The specific embodiments of this utility model will be further described below with reference to the accompanying drawings and examples. The following examples are only used to more clearly illustrate the technical solution of this utility model and should not be construed as limiting the scope of protection of this utility model.

[0022] Please see Figure 1-6 This utility model provides a technical solution: a crack-resistant casserole with a biomimetic honeycomb structure, including a pot body 1, the pot body 1 including an inner liner 101, a biomimetic honeycomb layer 102 and a protective layer 103 from the inside out.

[0023] Furthermore, the biomimetic honeycomb layer 102 is composed of hexagonal honeycomb units arranged in an array. The wall thickness of the hexagonal honeycomb units is 0.5 to 2 mm, and the side length is 5 to 15 mm. The inner liner 101 is made of high thermal conductivity clay with a thickness of 2 to 3 mm and a smooth surface to improve the uniformity of heat conduction. The protective layer 103 has a thickness of 1 to 2 mm and is made of high-temperature resistant ceramic glaze to enhance mechanical strength.

[0024] Specifically, by setting up a biomimetic honeycomb layer 102, the pressure of the pot body 1 under thermal expansion is evenly distributed using the biomimetic principle of honeycomb. Compared with existing technologies, this significantly reduces the risk of the pot body 1 cracking due to sudden temperature changes, promotes the dispersion of thermal stress in the pot body 1, thereby enhancing the impact resistance of the pot body 1 and effectively preventing the pot body 1 from cracking.

[0025] The pot body 1 has a pot opening 2 at the top, and a pot lid 4 is provided on the pot opening 2. An annular strip 3 that matches the pot lid 4 is fixed on the inner wall of the pot opening 2. A sealing ring that matches the annular strip 3 is installed on the edge of the pot lid 4, thereby forming a sealed air cavity to slow down heat loss. A pot lid handle 5 is installed on the top of the pot lid 4.

[0026] Furthermore, the pot lid handle 5 includes a connecting block 51 fixed to the pot lid 4. A gripping block 54 is fixed to the top of the connecting block 51. Notches and grooves 55 are evenly provided around the gripping block 54. When gripping, the fingers naturally fit into the notches and grooves 55, which avoids burning the hands and improves the stability of operation, achieving the effects of anti-slip heat dissipation and ergonomic adaptation.

[0027] Furthermore, the connecting block 51 has a radially arranged insertion hole 52, and a side insertion groove 53 communicating with the insertion hole 52 is opened on one side of the connecting block 51;

[0028] Specifically, in practical applications, to avoid scalding the pot lid 4, long-handled kitchen utensils such as soup ladles can be inserted into the socket 52 to lift the pot lid 4, thus achieving a scalding effect. At the same time, long-handled kitchen utensils such as soup ladles can be directly inserted into the socket 52 from the side insertion groove 53, making it easier to insert and remove, and more convenient to use.

[0029] The side of the handle 5 of the pot lid is provided with an adjustable vent structure 6. The adjustable vent structure 6 includes a vent tube 601 that communicates with the inside of the pot lid 4. The vent tube 601 is formed together with the pot lid 4. An exhaust pipe 603 is inserted into the vent tube 601. An exhaust hole 606 with an inverted cone shape at the bottom is opened in the exhaust pipe 603. A plug 608 that can move up and down is movably connected in the exhaust hole 606. A heat insulation cover 607 that seals the top of the exhaust pipe 603 is fixed at the top of the plug 608.

[0030] Specifically, by setting an adjustable vent structure 6 and using a plug 608, the opening and closing degree of the vent 606 can be adjusted by moving it up and down. Compared with existing technologies, it can achieve flexible switching from slow venting through micropores to fast venting with full opening, adapting to different cooking needs such as stewing and reducing sauce, and achieving the effect of multi-stage steam release.

[0031] Furthermore, the ventilation pipe 601 is provided with locking blocks 602 on both sides, and the exhaust pipe 603 is fixed with a silicone sleeve 604 at the top. The silicone sleeve 604 is provided with a slot 605 that fits with the locking blocks 602.

[0032] Specifically, by setting up a silicone sleeve 604, a card block 602, and a card slot 605, and adopting a plug-in structure, users can disassemble and clean the relevant components of the adjustable air hole structure 6 by hand. This not only allows for quick disassembly and assembly but also achieves a sealing and leak-proof effect, making it more convenient to use.

[0033] Furthermore, a threaded sleeve 610 connected to the plug 608 is fixed to the inner wall of the top of the vent hole 606. A blocking ring 609 is provided below the threaded sleeve 610 and is fitted on the outside of the plug 608. The blocking ring 609 is fixed to the inner wall of the vent hole 606. A through hole 611 is provided on the blocking ring 609, and a through hole 612 is provided inside the threaded sleeve 610.

[0034] Specifically, by setting threaded sleeve 610, barrier ring 609, through hole one 611 and through hole two 612, and utilizing the staggered distribution of through hole one 611 and through hole two 612, an airflow resistance gradient is formed. This not only avoids concentrated steam gushing but also prevents backflow of external impurities, achieving the effect of multi-stage steam buffering and anti-backflow.

[0035] Specifically, by rotating the heat insulation cover 607, the plug 608 is moved up and down. When the bottom of the plug 608 separates from the inner wall of the vent 606, the vent 606 begins to exhaust air. In conjunction with the through hole 1 611 and the through hole 2 612, the airflow is discharged from the vent 606. As the plug 608 gradually moves upward, the open area at the bottom of the vent 606 gradually increases, promoting exhaust.

[0036] Furthermore, a handle 7 is fixed on one side of the pot body 1, and a placement groove 8 is provided on the top of the handle 7 to fit the edge of the pot lid 4; by using the pot opening 2 and the placement groove 8 to fit together, the pot lid 4 can be tilted and placed on the pot opening 2.

[0037] Furthermore, a handle 2 9 is fixed to one side of the pot body 1. A storage sleeve 10 is movably fitted onto the handle 2 9. A pair of connecting rods 11 are fixed to the storage sleeve 10. A limiting block 12 is fixed to the top of the connecting rod 11. The storage sleeve 10, connecting rods 11 and limiting block 12 are all made of silicone, which has a certain heat insulation effect. Long-handled kitchen utensils such as soup ladles can be placed between adjacent limiting blocks 12, so that the head of the soup ladle is above the pot mouth 2, preventing soup from dripping onto the table and making it convenient to use.

[0038] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
