[0021] 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.

[0022] Please see Figure 1-4 This utility model provides a technical solution: a temperature-compensated spice constant-temperature storage tank, including a bottom box structure, an outer tank 1 and an inner tank 8. The outer tank 1 is provided on the top of the bottom box structure and is detachably connected to the bottom box structure. The interior of the outer tank 1 is hollow, and the inner tank is inserted into the interior of the outer tank 1. A sealing plate 2 is provided on the top of the inner tank 8. Several protruding plates 3 are provided at equal intervals on the outer wall of the inner tank 8. Several guide grooves are provided on the inner wall of the outer tank 1, and the protruding plates 3 can be embedded in the guide grooves. A lateral heat conduction structure is provided between adjacent guide grooves. A protruding tube 4 is provided at the top center of the sealing plate 2. A touch screen 5 is provided on the side wall of the protruding tube 4. Several temperature sensors 6 are provided on the inner side of the sealing plate 2.

[0023] The side-heating structure includes an arc-shaped heating box 7, which contains several heating resistors. An arc-shaped heat-conducting plate 9 is located on the inner wall of the heating box. The heat-conducting plate 9 can contact the outer wall of the inner tank. The heating box 7 is heated by the heating resistors inside, and the heat is then conducted through the heat-conducting plate 9 and transferred to the outer wall of the inner tank 1, thus heating from the side.

[0024] The bottom box structure includes a base plate 10, the top of which is provided with an annular protrusion 11. A heating box 2 12 is provided at the center of the inside of the base plate 10. A heating rod 13 is provided at the top of the heating box 2 12. The heating rod 13 is inserted into the bottom of the inner tank 8. The heating is carried out by heating the inner tank 1 through the heating box 2 12 inside the base box 10, and then the heat is conducted from the heating rod 13 to the inside of the inner tank 1.

[0025] The seat plate 10 has several slot holes inside, and the bottom of the outer tank 1 has several corresponding insert rods. The insert rods are inserted into the slots. By using the slot holes inside the seat plate 10 to insert the insert rods, the inner tank 8 is limited and fixed.

[0026] The bottom of the inner tank 8 is provided with a column groove, the inner wall of the column groove is provided with a heat-conducting sleeve 14, and the top of the column sleeve is provided with a heat-conducting rod 15. The heat-conducting rod 15 extends into the interior of the inner tank, and heat is conducted to the interior of the inner tank 8 through the heat-conducting sleeve 14 and the heat-conducting rod 15.

[0027] The top of the cover plate 2 has several through holes, and a sealing plug 16 is inserted into the through holes. The sealing can be strengthened by the sealing plug 16, or it can be opened to quickly release excess air inside.

[0028] Working Principle: Through the nested structure of the inner and outer canisters 1, and the temperature control heating components distributed at the bottom and side walls of the canisters, combined with multi-point temperature sensing and heat conduction structures, a dynamic constant temperature compensation system is formed to achieve constant temperature storage of spices. The system is initialized upon power-up. The user inserts the inner canister into the outer canister 1, which is then inserted into the bottom box structure and fixed in place by the insertion rod and slot. After power-up, the temperature control system starts, and the temperature sensor 6 inside the top cover plate 2 begins to collect temperature data from multiple locations within the inner canister in real time. Temperature monitoring and feedback control: Temperature sensor 6 transmits the collected data to the temperature control main board, which can be integrated into the touch screen module 5. If the detected temperature is lower than a set threshold, such as 25°C, the control system triggers the temperature control mechanism, activating the heating rods 13 in heating box 1 7 and heating box 2 12. Heat conduction and temperature compensation occur as the heating rods 13 generate heat, which is then evenly conducted to the outer wall of the inner tank via the arc-shaped heat-conducting plate 9. Simultaneously, the bottom heating rods 13 conduct heat from bottom to top to the center area of the inner tank via the heat-conducting sleeve 14 and heat-conducting rod 15 within the column groove, achieving heat transfer from the bottom and side walls. Two-way heating; heat is evenly distributed inside the inner tank, keeping the fragrance in a stable, constant temperature environment. Sealing and fragrance preservation: the sealing plug 16 at the top of the cover plate 2 is inserted into the through hole to form a good seal, preventing outside air and moisture from entering the tank; reducing fragrance volatilization and oxidation, maintaining the purity and activity of the aroma. User control and adjustment: users can view the current temperature in real time through the touch screen 5 on the convex tube 4 and set the target temperature; closed-loop feedback control is performed based on the set value to intelligently adjust the heating intensity and achieve precise temperature maintenance; supports automatic temperature control, manual adjustment, or timer functions.

All components are general standard parts or parts known to those skilled in the art. Their structure and principles can be learned by those skilled in the art through technical manuals or conventional experimental methods. This utility model solves the problems of traditional... Storage tanks are mostly sealed or insulated structures, but they cannot actively regulate the internal temperature. This makes them prone to spoilage, oxidation, or aroma volatilization of spices under conditions of large temperature differences. This invention addresses this issue by combining the aforementioned components. Through the bottom and side-mounted heating boxes (I and II), combined with an arc-shaped heat-conducting structure and heat-conducting rods, it achieves comprehensive temperature compensation for the inner tank, ensuring that spices are stored within a constant and suitable temperature range. This effectively prevents spices from volatilizing, oxidizing, or becoming moldy due to low-temperature humidity or high-temperature dryness. The modular design of the inner and outer tanks facilitates disassembly, cleaning, and replacement. The outer tank and bottom box structure are detachably connected, and the inner tank can also be removed from the outer tank, making it convenient for users to clean, maintain, or replace spices, thus improving practicality and hygiene management. Multi-point temperature monitoring and precise control of the temperature compensation system are achieved. Multiple temperature sensors inside the cover plate collect temperature information from multiple points inside the storage tank in real time, and the heating intensity is adjusted to achieve precise temperature control. The multi-stage heat conduction structure improves heating efficiency. The heating rods inside the heating box are in close contact with the outer wall of the inner tank, while the heat conduction rods in the bottom column grooves further conduct heat to the central area of the tank, effectively avoiding uneven heating and local cooling, and improving the stability of temperature control and energy efficiency ratio.
