Abstract
Description
Technical Field
[0001] This utility model relates to the field of graphite technology, and in particular to an energy-saving, temperature-regulating cookware. Background Technology
[0002] Energy-saving cookware refers to cookware that significantly reduces energy consumption (such as gas or electricity) during cooking through special structural design, material optimization, or functional innovation, while improving thermal efficiency or cooking results. Its core objective is to achieve an efficient, fast, and environmentally friendly cooking experience while reducing energy waste.
[0003] Existing energy-saving cookware often uses fixed clips or adhesive bonding for its heat insulation sleeves. After prolonged use, these sleeves are prone to loosening or falling off due to high-temperature aging, and it's difficult to thoroughly clean grease from the gaps. Disassembly requires tools, making the process cumbersome and reducing user experience. Furthermore, the sealing of existing clip-on lids relies on manual force; if not fully secured, steam can leak through gaps, causing the micro-pressure effect to fail, extending cooking time, and failing to meet long-term energy-saving requirements. Therefore, this paper proposes an energy-saving, temperature-regulating cookware to address these issues. Utility Model Content

[0032] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.
[0033] Reference Figure 1 , Figure 2 , Figure 4 Figure 5 An embodiment of this utility model is provided: an energy-saving and temperature-regulating cookware, including an outer pot body 1, a sealing ring 17 fixedly connected to the top of the outer pot body 1, a connecting component installed on the outside of the outer pot body 1, and a sealing component installed on the outside of the outer pot body 1.
[0034] The connecting assembly includes a handle 5, which is fixedly connected to the outside of the outer pot body 1. A heat insulation sleeve 4 is slidably connected to the outside of the handle 5. A shell 7 is fixedly connected to the top of the heat insulation sleeve 4. A locking post 8 is slidably connected to the middle of the shell 7. A locking groove 11 is provided in the middle of the handle 5, and the locking groove 11 engages with the locking post 8. A pull ring 9 is provided at the top of the locking post 8, and a spring 10 is sleeved on the outside of the locking post 8. A slot 6 is provided in the middle of the heat insulation sleeve 4. The handle 5 is slidably connected to the middle of the slot 6. When the heat insulation sleeve 4 is slid along the handle 5 to the fit position, an air gap is formed between the internal slot 6 of the heat insulation sleeve 4 and the handle 5, which blocks heat transfer. Under the elastic force of the spring 10, the locking post 8 automatically locks into the locking groove 11 in the middle of the handle 5, ensuring that the heat insulation sleeve 4 is tightly fixed to the handle 5 and preventing it from falling off during cooking. When the heat insulation sleeve 4 is old and damaged, pull the pull ring 9 upward to overcome the elastic force of the spring 10 and lift the locking post 8, so that it is disengaged from the locking groove 11. The heat insulation sleeve 4 can then be removed from the handle 5 for easy replacement without replacing the entire cookware, thus reducing usage costs. A graphite pot body 16 is fixedly connected to the inside of the outer pot body 1. The graphite pot body 16 is provided with a wear-resistant layer 19 on the outside and a non-stick coating 18 on the outside of the wear-resistant layer 19. The high thermal conductivity of the graphite pot body 16 can ensure uniform heat distribution and reduce energy loss caused by local overheating. The wear-resistant layer 19 and the non-stick coating 18 reduce food adhesion, minimize heat loss during stir-frying, and improve cleaning efficiency. A lid 2 is fixedly mounted on the top of the outer pot body 1, and a handle 3 is fixedly connected to the center of the lid 2. The outer pot body 1 is made of stainless steel.
[0035] Reference Figure 1 and Figure 3 The sealing assembly includes a fixing frame 12, which is fixedly connected to the outside of the outer pot body 1. A connecting rod 13 is rotatably connected to the inside of the fixing frame 12. A threaded rod 14 is threadedly connected to the middle of the connecting rod 13, and a fixing block 15 is fixedly connected to the top of the threaded rod 14. The bottom of the threaded rod 14 contacts the pot lid 2. After the pot lid 2 is closed, rotating the fixing block 15 drives the threaded rod 14 to rotate, causing the threaded rod 14 to move downwards and press against the pot lid 2. The sealing ring 17 at the top of the outer pot body 1 is deformed by compression, filling the gap between the pot lid 2 and the pot body. This causes steam to accumulate inside the pot, creating micro-pressure, which raises the boiling point of the liquid, accelerates the cooking speed of the food, shortens the cooking time, reduces steam leakage, and reduces heat loss.
[0036] Working principle: When installing the heat insulation sleeve 4, first pull the pull ring 9 to drive the locking post 8 to compress the spring 10. After the handle 5 is inserted into the interior of the heat insulation sleeve 4 through the slot 6, release the pull ring 9 so that the locking post 8 is inserted into the slot 11 of the handle 5 by the elastic force of the spring 10, ensuring that the heat insulation sleeve 4 is stably fixed on the handle 5, thus achieving quick installation. When it is necessary to remove the heat insulation sleeve 4 for cleaning, pull the pull ring 9 to lift the locking post 8 to compress the spring 10, release the lock of the slot 11, and achieve quick disassembly of the heat insulation sleeve 4.
[0037] The rotating fixing block 15 drives the threaded rod 14 to rotate, causing the threaded rod 14 to move downwards and press against the pot lid 2. The sealing ring 17 ensures a tight fit between the outer pot body 1 and the pot lid 2, which helps reduce steam leakage. Steam accumulates inside the pot, creating a slight pressure, improving heat transfer efficiency and shortening cooking time. Utilizing the low thermal conductivity of air, a gap is left between the graphite pot body 16 and the outer pot body 1 to form a natural insulation layer, reducing convective heat loss and improving overall heat insulation efficiency.
[0038] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. 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.
