Detailed Implementation

[0020] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this utility model, not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of this utility model.

[0021] In family life, especially during the cold season, household charcoal stoves have always been popular tools for heating and cooking. They not only provide warmth but also meet various daily needs such as cooking and boiling water. However, traditional household charcoal stoves have many limitations. For example, a common charcoal brazier is simply a fixed frame with a brazier, primarily focused on home heating, and its small size limits its applicability. While wood-burning stoves have a firebox, ash storage area, and chimney, their use is greatly restricted, making them difficult to move and use freely. Barbecue grills are typically long and narrow, consisting of a high support and a charcoal trough, offering relatively limited functionality. Furthermore, most traditional household charcoal stoves are not adjustable in length or height, making them unsuitable for different usage scenarios and uneven ground.

[0022] To overcome the shortcomings of traditional household charcoal stoves, this invention provides an adjustable, multi-purpose household charcoal stove. Through a unique support structure design, it achieves adjustability in length, height, and width, and is easy to install and adjust, adapting to various usage scenarios and uneven ground. Furthermore, the stove is equipped with a tabletop 1 and a mesh screen 3, allowing it to be used not only for home heating but also for grilling, tea brewing, and other functions, truly achieving multiple uses in one stove.

[0023] like Figure 1 and Figure 2 As shown, this adjustable multi-purpose household charcoal stove mainly consists of a tabletop 1, a supporting column 8, an upper bracket 4, a lower bracket 7, a charcoal pot 2, a separating mesh 3, and a water and oil collection tank 6. Its design concept aims to achieve multi-functionality and adaptability through a reasonable structural layout and adjustable components.

[0024] The tabletop 1 serves as both the support surface and the usable surface for the charcoal stove. It not only provides a platform for placing items but also includes a location for installing the insulating netting 3, ensuring a flat surface after installation. Support columns 8 are positioned at the four corners of the lower surface of the tabletop 1, connected to the upper support 4 and lower support 7 via right-angle joints 5, allowing for easy adjustment of the stove's height, length, and width. The first crossbeam 9 between the upper support 4 sections connects to the side beams 10, forming a placement cavity for the charcoal hot pot 2. A water and oil collection trough 6 is installed on the second crossbeam 12 between the lower support 7 sections.

[0025] like Figure 1 As shown, a mesh screen 3 is located in the center of the tabletop 1, and the surrounding area is the usable surface. This usable surface can be used to place barbecue tools, tea sets, and other items, or as a heating area, truly realizing the multi-functionality of a single stove. The size and shape of the tabletop 1 are carefully designed to meet the needs of daily family use, while also providing a suitable location for the installation of the mesh screen 3, ensuring flatness after installation.

[0026] The insulating net 3 plays a crucial role, separating the charcoal fire and providing users with multiple usage options. Users can place a teapot on the insulating net 3 for brewing tea; it can also be used for grilling, roasting sweet potatoes, meats, and other foods. The mesh pattern of the insulating net 3 can be made into different shapes such as round holes and oblong holes to control different grilling requirements, facilitating the adjustment of heat distribution and adapting to various cooking needs. Simultaneously, the insulating net 3 separates the charcoal fire from the usable surface of the table 1, effectively preventing direct contact between the charcoal fire and the table 1, preventing damage from high temperatures, greatly reducing the risk of burns to the user, and improving safety.

[0027] like Figure 1 As shown, the support columns 8 are located at the four corners of the lower surface of the tabletop 1, and are symmetrically distributed on the lower surface of the tabletop 1. This symmetrical arrangement allows the support columns 8 to be stably installed under the tabletop 1, enhancing the overall stability of the charcoal stove. Even on uneven ground, the charcoal stove can remain balanced and will not wobble or tilt. At the same time, the symmetrical design also makes the charcoal stove more aesthetically pleasing and harmonious in appearance.

[0028] The top and bottom of the supporting column 8 are connected to the upper bracket 4 and the lower bracket 7 via right-angle joints 5, respectively. The upper bracket 4 and the lower bracket 7 are connected to several crossbeams via three-way joints 11, forming the frame structure of the charcoal stove. The first crossbeam 9 between the upper brackets 4 connects to the side beams 10, and the second crossbeam 12 between the lower brackets 7 houses the water and oil collection troughs 6. This structural design ensures the stability and functionality of the charcoal stove.

[0029] like Figure 2 As shown, the lower support 7 connects several second crossbeams 12 via a three-way joint 11. In this embodiment, two second crossbeams 12 are preferably provided, and these second crossbeams 12 are specifically used to install the water and oil collection tank 6. The number and arrangement of the lower supports 7 are carefully designed, with several lower supports 7 symmetrically distributed on the same horizontal plane. In this embodiment, two lower supports 7 are preferably provided to ensure the stability and load-bearing capacity of the overall structure. Simultaneously, the second crossbeams 12 are also symmetrically arranged, which not only enhances the structural balance but also makes the installation of the water and oil collection tank 6 more stable. Furthermore, the three-way joint 11 is designed with an adjustable length, allowing users to flexibly adjust the length of the second crossbeams 12 according to actual needs, thereby changing the installation position of the water and oil collection tank 6. This design greatly improves the adaptability and flexibility of the equipment, meeting the installation needs of different scenarios. For example, in environments with limited space, users can optimize the layout by adjusting the crossbeam lengths, ensuring that the installation of the water and oil collection tank 6 is both reasonable and convenient.

[0030] The water and oil collection tray 6 is designed with multiple functions, significantly enhancing the user experience. When grilling, it holds a suitable amount of water, which gradually evaporates using the heat generated by the burning charcoal, releasing moist moisture. This design effectively alleviates the problem of dry air during grilling, improving the comfort of the environment, and is particularly suitable for prolonged grilling sessions, preventing discomfort caused by dry air. Furthermore, the water and oil collection tray 6 also serves an important cleaning function during grilling. It catches oil droplets from food, preventing them from dripping directly onto the ground or surrounding environment, thus avoiding oil contamination of the ground and surrounding facilities and maintaining a clean and hygienic environment.

[0031] The water and oil collection tank 6 is installed in an optimized position, typically placed directly below the charcoal hot pot 2. This layout not only maximizes the use of heat generated by the charcoal hot pot 2 and improves water evaporation efficiency, but also more effectively collects oil droplets dripping from the food. Because the water and oil collection tank 6 is located directly below the charcoal hot pot 2, oil droplets will not splash out during dripping, thus avoiding environmental pollution and fire hazards caused by oil splashing. This design not only improves the efficiency of the equipment but also significantly enhances its safety, reducing the risk of fire caused by oil splashing.

[0032] like Figure 2 As shown, the charcoal hot pot 2 is cleverly positioned directly below the insulating mesh 3, and its shape is hemispherical. This hemispherical structure is not only unique in appearance, but more importantly, it has significant functional advantages. The hemispherical design effectively concentrates heat and reduces heat loss, thereby significantly improving the efficiency of grilling and cooking. As the core component for storing charcoal, the size and specifications of the charcoal hot pot 2 can be selected according to the user's actual needs. Users can flexibly choose different sizes of charcoal hot pot 2 according to different usage scenarios and cooking needs to meet the needs of various occasions, from family gatherings to outdoor barbecues.

[0033] When users need to replace the charcoal hot pot 2 with one of different diameters, the design of the side beams 10 and the first crossbeam 9 of the equipment provides a high degree of flexibility. Users can easily change the size of the placement chamber by adjusting the length or position of the side beams 10 and the first crossbeam 9, making it perfectly adaptable to charcoal hot pots 2 of different diameters. This design not only simplifies the replacement process but also ensures that the charcoal hot pot 2 can be placed stably in the equipment, avoiding inconvenience or safety hazards caused by size mismatch. In addition, when users need to replace the charcoal hot pot 2 with one of different depths, the design of the support column 8 of the equipment also provides convenient adjustment functions. Users can quickly adjust the overall height of the support structure by adjusting the height of the support column 8, thereby ensuring that charcoal hot pots 2 of different depths can be placed stably and maintain the optimal distance between them and the isolation net 3 to achieve efficient heat transfer and uniform heating effect.

[0034] This adjustable design not only reflects the product's high versatility and flexibility but also fully considers the diverse needs of users in actual use. Whether it's replacing the charcoal hot pot 2 with a different size or adjusting the height of the device to adapt to different usage environments, users can quickly adapt through simple operations. This design not only enhances the product's practicality but also improves the user experience, enabling the device to be widely used in various scenarios and meet the personalized needs of different users. At the same time, this flexible design also extends the product's lifespan because users do not need to replace the entire device due to changes in the size of the charcoal hot pot 2, thereby reducing operating costs and improving the product's economic efficiency.

[0035] like Figure 2 As shown, the right-angle joint 5 connects the upper and lower supports 7 and the support column 8, allowing for easy adjustment of the height, length, and width of the charcoal stove. An adjustment knob 13 is located on the side of the right-angle joint 5, allowing users to adjust the height, length, and width of the upper and lower supports 7 and the support column 8 by rotating the knob 13. This adjustment method is very simple, requiring no complicated tools or operations, greatly improving the convenience of adjustment.

[0036] The right-angle joint 5 design not only enables the adjustability of the charcoal stove but also ensures a secure connection between all components. It can withstand various forces experienced by the charcoal stove during use, ensuring its overall stability and making it more reliable, preventing loosening or disintegration.

[0037] Compared to traditional household charcoal stoves, this utility model's charcoal stove has significant advantages. Traditional charcoal stoves have limited functions; for example, charcoal braziers are mainly used for heating, wood-burning stoves have many limitations, and barbecue grills are single-function and non-adjustable. This charcoal stove, however, with its adjustable support structure, can adapt to various usage scenarios and uneven ground, and its adjustment and installation are simple and convenient. Furthermore, it achieves multi-functionality, integrating heating, grilling, and tea brewing, meeting diverse needs of family life. In addition, this charcoal stove is equipped with a water and oil collection tank 6, solving the problems of dryness during heating and oil droplet contamination during grilling, improving comfort and safety during use.

[0038] Obviously, the above embodiments are merely illustrative examples for clear explanation and are not intended to limit the implementation. Those skilled in the art will recognize that other variations or modifications can be made based on the above description. It is neither necessary nor possible to exhaustively list all possible implementations here. However, obvious variations or modifications derived therefrom are still within the protection scope of this utility model.
