Description

Technical Field

[0001] This utility model belongs to the field of heating pot technology, specifically, it relates to a rechargeable heating pot. Background Technology

[0002] With the rise of the outdoor economy and the increasing demand for portable hot food in office commuting scenarios, rechargeable heating pots that do not require an external power grid have gradually become an important category in the portable kitchenware market. These products use batteries as their core energy source and, with their compact size and high mobility, effectively solve the pain point of users needing hot food in non-fixed locations (such as campsites, offices, and travel), becoming key products for improving the convenience of life.

[0003] However, current rechargeable heating pots on the market suffer from two major flaws in battery design and application, which severely restrict the economic viability of production and their market competitiveness:

[0004] Poor battery specification compatibility leads to high user costs.

[0005] Most existing rechargeable cookware uses an embedded battery design, with the battery fixedly integrated into the main body of the cookware. This severely limits the battery size and capacity—users cannot choose different battery specifications based on their actual needs (e.g., a small-capacity battery for short commutes, a large-capacity battery for long camping trips). Furthermore, due to the space constraints of the embedded structure, manufacturers typically need to use specialized batteries with high energy density (such as high-capacity cylindrical lithium batteries). These batteries have complex manufacturing processes, resulting in significantly higher unit power costs compared to standard batteries (cost differences can reach 30%-50%). This higher cost is ultimately passed on to the final product price, leading to relatively high prices for existing rechargeable cookware and failing to meet the cost-effectiveness requirements of mass consumers for portable kitchen appliances, thus limiting market acceptance.

[0006] The battery is greatly affected by the heating components, resulting in a significant decrease in battery life and endurance.

[0007] With an embedded battery design, the battery is physically close to the heating elements (such as the heating element or the pot body) and lacks an effective separation structure. The high temperatures generated by the heating elements during operation (the bottom of the pot can reach 150-200℃) are easily transferred to the battery through heat conduction, causing the battery's operating temperature to exceed its optimal range (typically 0-45℃). Prolonged exposure to high temperatures not only causes temporary capacity degradation (reducing battery life by 20%-40%), but also accelerates the aging of internal chemical substances, shortening battery cycle life (from the normal 500 cycles to below 300 cycles), increasing the frequency and cost of subsequent battery replacements, and further degrading the user experience.

[0008] Insufficient battery replacement convenience and poor maintenance flexibility

[0009] Even though some products support battery replacement, it requires complex operations such as disassembling the outer shell and plugging and unplugging multiple connecting cables. A single replacement typically takes more than 5 minutes and requires tools, failing to meet users' needs for "rapid recharging" in outdoor and other scenarios. Furthermore, the fixed battery specifications are incompatible with standardized batteries of different brands and capacities, requiring users to purchase manufacturer-specific batteries separately, further increasing usage costs and hindering product market penetration.

[0010] In summary, existing rechargeable heating pots suffer from battery design flaws, resulting in problems such as "limited specifications, high cost, significant heat-affectedness, and inconvenient replacement." These issues neither meet the economic requirements of manufacturers for large-scale production nor satisfy users' demands for "low cost, long battery life, and high flexibility." Therefore, a battery design solution that balances production economics and user practicality is urgently needed. In view of this, this utility model is proposed.

[0011] In view of this, this utility model is hereby proposed. Utility Model Content

[0012] To address the limitations of current rechargeable heating pots in terms of battery size and capacity, which prevent users from selecting different battery specifications based on their actual needs, and the fact that batteries are susceptible to heat generated by the heating element, affecting their battery life and performance, the basic concept of this utility model is as follows:

[0013] A rechargeable heating pot includes a base and a housing mounted on the base. A mounting seat is fixedly connected to the side wall of the housing, and a battery assembly that can be quickly installed and removed is connected to the mounting seat. The battery assembly is provided with a locking mechanism for locking the battery assembly. A pot body is provided inside the housing, and a heating component is installed between the pot body and the base.

[0014] In a preferred embodiment of the present invention, the mounting base includes a plug groove extending outward along the side wall of the outer shell, and a male connector mounted on the base. The battery assembly is provided with a plug portion adapted to the plug groove, and the plug portion is provided with a female connector corresponding to and adapted to the male connector.

[0015] In a preferred embodiment of this utility model, the battery assembly has a movable groove and an installation groove and a sliding groove communicating with the movable groove. A locking block is slidably installed in the movable groove, and a limiting rod is slidably installed in the installation groove. The limiting rod is fixedly connected to the locking block, and a spring is sleeved on the limiting rod. One end of the spring abuts against the bottom of the movable groove, and the other end abuts against the bottom of the locking block. The mounting base has a locking groove that matches the locking block.

[0016] In a preferred embodiment of this utility model, a connecting rod is slidably installed in the sliding groove, and an inclined guide groove is provided on the side of the locking block facing the sliding groove. One end of the connecting rod cooperates with the guide groove, and the other end is connected to a button. A solar panel is fixedly attached to the outer surface of the battery assembly, and the battery assembly is provided with different capacities and different sizes.

[0017] In a preferred embodiment of this utility model, the heating component is a ceramic heating element, which is directly attached to the bottom surface of the pot body. The side walls and bottom surface of the pot body are both covered with a heat insulation layer, which is heat insulation cotton, heat insulation film or heat insulation bubble.

[0018] In a preferred embodiment of this utility model, a pot lid is hinged to the outer shell, and a control board and a switch are also installed on the base. The control board is electrically connected to the heating component, the switch and the battery component respectively.

[0019] Compared with the prior art, the present invention has the following advantages:

[0020] This utility model assembles the battery assembly onto the side wall of the outer casing via a mounting base with a locking structure, flexibly adapting to battery assemblies of different sizes and capacities to meet diverse usage needs. The battery can be quickly replaced by pressing to unlock and aligning the insertion. The locking structure can securely maintain the connection between the battery and the heating pot. At the same time, the side wall mounting layout allows the battery assembly and the heating assembly to be naturally separated, effectively preventing the heat from the heating assembly from affecting the battery.

[0021] The specific embodiments of this utility model will be described in further detail below with reference to the accompanying drawings. Attached Figure Description

[0031] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the technical solutions in the embodiments will be clearly and completely described below with reference to the accompanying drawings. The following embodiments are used to illustrate this utility model.

[0032] like Figures 1 to 7 As shown, a rechargeable heating pot includes a base 1 and a housing 2 mounted on the base 1. A mounting seat 4 is fixedly connected to the side wall of the housing 2, and a battery assembly 5 that can be quickly installed and removed is connected to the mounting seat 4. The battery assembly 5 is provided with a locking mechanism for locking the battery assembly 5. A pot body 9 is provided inside the housing 2, and a heating component 6 is installed between the pot body 9 and the base 1. In this configuration, by mounting the battery assembly 5 to the side wall of the housing 2 with the mounting seat 4, the battery assembly 5 is kept at a distance from the heating component 6 located between the pot body 9 and the base 1. At the same time, the locking mechanism enables quick fixing and removal of the battery assembly 5, preventing the heat from the heating component 6 from directly acting on the battery assembly 5, and providing convenience for replacing the battery assembly 5. The housing 2 and the base 1 together provide a mounting support base for the pot body 9 and the heating component 6.

[0033] like Figures 1 to 7 As shown, in a specific embodiment, the mounting base 4 includes a plug groove 41 extending outward along the side wall of the outer casing 2, and a male connector 42 mounted on the base 1. The battery assembly 5 is provided with a plug portion 511 adapted to the plug groove 41, and the plug portion 511 is provided with a female connector 512 corresponding to and adapted to the male connector 42. In this configuration, the plug groove 41 of the mounting base 4 and the plug portion 511 of the battery assembly 5 cooperate to provide guidance and positioning for the installation of the battery assembly 5. During the process of the plug portion 511 being guided and inserted with the plug groove 41, it can drive the female connector 512 to mate with the male connector 42, thereby realizing the electrical connection between the battery assembly 5 and the device.

[0034] like Figures 1 to 7As shown, the battery assembly 5 further includes a movable groove 51 and a mounting groove 52 and a sliding groove 53 communicating with the movable groove 51. A locking block 54 is slidably installed in the movable groove 51, and a limiting rod 55 is slidably installed in the mounting groove 52. The limiting rod 55 is fixedly connected to the locking block 54, and a spring 56 is sleeved on the limiting rod 55. One end of the spring 56 abuts against the bottom of the movable groove 51, and the other end abuts against the bottom of the locking block 54. The mounting base 4 has a locking groove 43 that matches the locking block 54. In this configuration, the limiting rod 55 restricts the sliding of the locking block 54 and supports the spring 56. The spring 56 applies a spring force to the locking block 54 toward the mounting base 4. When the battery assembly 5 is installed in place, the locking block 54 can be locked into the locking groove 43 of the mounting base 4 under the action of the spring 56, thereby locking the battery assembly 5 onto the mounting base 4.

[0035] like Figures 1 to 7 As shown, a connecting rod 57 is slidably installed in the sliding groove 53. A guide groove 58 is inclined on one side of the locking block 54 facing the sliding groove 53. One end of the connecting rod 57 engages with the guide groove 58, and the other end is connected to a button 59. A solar panel 510 is fixedly attached to the outer surface of the battery assembly 5. The battery assembly 5 is available in different capacities and sizes. In this configuration, pressing the button 59 moves the connecting rod 57 along the sliding groove 53. The connecting rod 57 engages with the inclined guide groove 58 of the locking block 54, converting the pressing action into a force that pushes the locking block 54 to compress the spring 56, causing the locking block 54 to disengage from the locking slot 43 and unlock the battery assembly 5. The solar panel 510 can receive light energy and convert it into electrical energy to replenish the battery assembly 5. The design of battery assemblies 5 with different capacities and sizes can adapt to the range requirements of different usage scenarios and can be adapted to the mounting base 4 through a unified docking structure.

[0036] like Figures 1 to 7 As shown, the heating element 6 is a ceramic heating element, which is directly attached to the bottom surface of the pot body 9. The side walls and bottom surface of the pot body 9 are covered with a heat insulation layer, which is heat insulation cotton, heat insulation film, or heat insulation bubble. In this configuration, the heating element 6 directly conducts heat to the pot body 9, improving heat conduction efficiency. The heat insulation layer on the pot body 9 can prevent heat inside the pot body 9 from being lost to the outer shell 2 and the external environment.

[0037] like Figures 1 to 7 As shown, a lid 3 is hinged to the outer shell 2, and a control board 7 and a switch 8 are also installed on the base 1. The control board 7 is electrically connected to the heating component 6, the switch 8, and the battery component 5. In this configuration, the control board 7 can receive the operation signal transmitted by the switch 8, and control the battery component 5 to output power to the heating component 6 according to the signal, thereby controlling the working state of the heating component 6 and completing the heating start-up, shutdown, and adjustment.

[0038] The implementation principle of a rechargeable heating pot in this embodiment is as follows: When the rechargeable heating pot is working, the battery assembly 5 is first inserted into the mounting base 4 through its plug-in part 511 aligned with the plug-in slot 41. During the insertion process, the female connector 512 of the battery assembly 5 is gradually connected to the corresponding male connector 42 of the mounting base 4 to achieve electrical connection.

[0039] At the same time, the locking block 54 in the moving groove 51 of the battery assembly 5 will be squeezed by the outer wall of the mounting base 4, compressing the spring 56 on the limiting rod 55 in the mounting groove 52 and retracting into the moving groove 51 until the locking block 54 is aligned with the slot 43 of the mounting base 4. The spring 56 will then reset and push the locking block 54 into the slot 43, thus completing the rapid fixing of the battery assembly 5 through the locking mechanism.

[0040] When it is necessary to replace the battery assembly 5 with one of different capacity or size, press the button 59 on the battery assembly 5. The button 59 will move the connecting rod 57 in the sliding groove 53. One end of the connecting rod 57 will slide along the inclined guide groove 58 of the locking block 54, pushing the locking block 54 into the moving groove 51 and disengaging it from the locking groove 43. Then the battery assembly 5 can be pulled out for replacement. The solar panel 510 on the outer surface of the battery assembly 5 can assist in replenishing the battery.

[0041] When using the equipment for heating, the switch 8 on the operating base 1 receives a signal from the control board 7 and controls the heating component 6 to work. The ceramic heating element directly conducts heat to the pot body 9 to heat the food inside. The heat insulation layer, heat insulation cotton, heat insulation film or heat insulation bubbles wrapped around the side wall and bottom of the pot body 9 can reduce heat loss to the outside and ensure heating efficiency.

[0042] During the heating process, the battery assembly 5 is mounted on the side wall of the outer shell 2 via the mounting base 4, maintaining a distance from the heating assembly 6 between the base 1 and the pot body 9. This prevents the heat from the heating assembly 6 from directly affecting the battery assembly 5. After heating is complete, the pot lid 3 hinged on the outer shell 2 can be opened to take out and put in food. If it is necessary to disconnect the power supply, the battery assembly 5 can be removed by repeatedly pressing the button 59.
