Description

Technical Field

[0001] This utility model relates to the field of outdoor cooking utensils, and more particularly to a support device for a wood-burning stove and a foldable wood-burning stove. Background Technology

[0002] Wood-burning stoves are used in the field of outdoor cooking appliances, especially suitable for outdoor camping and fieldwork, providing users with a heat source solution that does not require electricity or gas to meet basic cooking needs. Patent document CN218237540U discloses a wood-burning stove support and a portable wood-burning stove with this support. The support mainly uses a fixed hinge to achieve simple opening and closing, but its lateral support is poor. When the stove body is subjected to external forces (such as wind or uneven ground) or when carrying heavy cooking utensils, the support legs are prone to lateral swaying or even tipping over, posing a safety hazard. Relying on only a single hinge axis, all the force is concentrated on the hinge axis. Over long-term use, with repeated opening and closing operations, the hinge hole will be subjected to frequent friction and compression. Over time, the hinge hole will gradually wear down, leading to a larger fit clearance and a loose support. A loose support is more unstable during use, further increasing the safety risk. Moreover, the situation will become even worse in rainy weather. Rainwater accelerates the rusting process of the hinge shaft and shaft hole. Rust fills the gap between the shaft and the hole, making opening and closing extremely difficult. In severe cases, the bracket may become completely unable to open due to rust, affecting the normal use of the stove and making it difficult to fold and store. Summary of the Invention

[0019] 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, not all, of the embodiments of this utility model.

[0024] like Figures 1 to 9 As shown, a support device 4 for a wood-burning stove includes a first support component 41, a second support component 42, and a position adjustment component 43. The support body 411 is provided with a connecting channel 412, which is used to connect to the bottom of the wood-burning stove. The second support component 42 is connected to the support member through the support member rotation shaft 45 and is rotatably connected. When the first support component 41 and the second support component 42 are connected, part of their structures overlap. The position adjustment component 43 is used to connect with the first support component 41 and the second support component 42 and adjust their unfolded and folded states. The position adjustment component 43 is movable between a locked position and an unlocked position relative to the second support component 42 or the first support component 41. In the locked position, it can hold the second support component 42 in the supported position. The first support component 41 and the second support component 42 are adjusted in position by means of the position adjustment component 43. The adjustment component 432 includes a connecting part, a locking part, an adjustment part, and a driving part that are sleeved and connected to the connecting part 431. When the locking part is located in the locking area 441, it holds the second support component 42 in the supported position relative to the first support component 41. When the adjustment part is located in the movable area 442, it adjusts the second support component 42 to a folded state relative to the first support component 41. The position adjustment component 43 is a key mechanism for realizing the transition between a stable unfolded state and a compact folded state of the support device 4 between the first support component 41 and the second support component 42.

[0025] like Figures 1 to 9 As shown, the active area 442 and the locking area 441 are interconnected. The active area 442 is an elongated structure with an arc shape along the end of the second support component 42. The width of the active area 442 is smaller than the width of the locking area 441. The shape of the locking area 441 matches the external shape of the locking part. When the user operates, they grip the driving part of the adjusting member 432 and press it outwards to disengage the locking part of the adjusting member 432 from the locking area 441 of the second support component 42. At the same time, the reset member 433 is compressed and the adjusting member 432 is driven to move axially along its connecting member 431, disengaging from the locked position. Subsequently, by pushing the driving part, the adjusting member 432 slides along the preset arc-shaped active area 442, allowing the user to rotate the second support component 42 relative to the first support component 41. When both are rotated to a predetermined horizontal unfolded state (support position), the driving part is released, the compressed reset member 433 releases energy, and pushes the locking part to quickly spring back to the locking area 441.

[0026] The special contour design of the locking area 441 tightly engages with the locking part, forming a strong mechanical interference. This physically and rigidly constrains the relative movement between the two support members, preventing movement in the folding direction and thus providing stable and reliable support. When folding for storage, the initial operation steps are the same: gently pull the drive unit to disengage the locking part from the locking area 441 and compress the reset member 433. Maintaining this unlocked state, rotate the second support assembly 42 towards the first support assembly 41. The adjusting member 432 then slides along the arc-shaped moving area 442 towards the end positioning point of the folding end. At this time, the first support assembly 41 is fully embedded in the storage groove designed for the second support assembly 42, and the two fit tightly together. The folding mechanism minimizes the overall volume. This design uses the drive unit to apply force in a specific direction to overcome the resistance of the reset member 433, precisely switching between locked and unlocked states. In the locked position, the tight engagement between the locking part and the locking area 441 forms a rigid connection point, forcefully fixing the support member in the unfolded position and ensuring rigidity and stability during use. In the unlocked position, the locking part disengages and the adjusting member 432 can slide freely in the movable area 442, completely releasing the constraint on the relative rotation of the support member, allowing for easy and smooth folding or unfolding. This enables the support device 4 to flexibly switch between a fully stable unfolded state and a minimum volume storage state, perfectly balancing the needs of strength and portability.

[0027] like Figures 1 to 9 As shown, the first support component 41 in this utility model includes a support body 411, on which a connecting channel 412 is provided. One or more connecting channels 412 can be provided. If multiple channels are provided, the stability of the connection can be significantly enhanced. The connecting channel 412 can be connected to the bottom of the wood stove by fasteners such as screws and bolts. In this way, assembly and disassembly become extremely convenient, and the overall structure is more stable after installation.

[0028] like Figures 1 to 9 As shown, in this embodiment, the support body 411 consists of a support portion 1 and a support portion 2 formed by bending along it. Two support portions 2 are provided, and they are approximately equal in length to the support portion 1. This structural design is ingenious; the support portion 1 and support portion 2 work together to form a good load-bearing structure, capable of withstanding greater weight and pressure, ensuring the stability and reliability of the wood-burning stove during use.

[0029] like Figures 1 to 9As shown, the position adjustment component 43 includes a connector 431, an adjusting component 432, and a reset component 433 sleeved on the connector 431. The adjusting component 432 is connected to at least one end of the connector 431. The two ends of the connector 431 are respectively rotatably connected to the second support component 42. The reset component 433 can be selected in various ways. In this invention, a spring is preferred as the reset component 433 because it has good elasticity and reset capability. In addition, soft rubber, silicone or other various deformation structures can also be used as the reset component 433, which can also meet the reset requirements of the position adjustment component 43, providing convenience for the use and storage of the wood stove.

[0030] like Figures 1 to 9 As shown, the active area 442 has an end position, which is located away from the locking area 441. When the adjusting member 432 moves to the end position, the second support component 42 and the first support component 41 are in a fully folded state. The first support component 41 is located inside the second support component 42 and is partially wrapped by the second support component 42. The main body of the first support component 41 is a plate-shaped structure, and one end of it has a channel structure for connecting the stove base 3. The stove base 3 can be inserted into the channel through fasteners to achieve a stable connection with the support device 4. The second support component 42 is also plate-shaped, and one side of it is connected to the side of the first support component 41 through a rotating shaft, so that the two can rotate relative to each other around the rotating shaft. When the two are in the connected state, part of the plate surface of the first support component 41 will overlap with part of the plate surface of the second support component 42, reserving space for subsequent folding and storage.

[0031] like Figures 1 to 9As shown, a portable wood-burning stove includes a foldable main body unit 1, a top plate 2, and a base 3. The main body unit 1 consists of multiple sets of adjacent, rotatable mounting plates. Each mounting plate includes detachably connected inner side plates 5 and outer side plates 6. Each inner side plate 5 includes a plate body and connecting portions 51 extending along both sides of the plate body. At least one connecting portion 51 is distributed along the length direction. Adjacent inner side plates 5 are rotatably connected to a connecting shaft 7 along the length direction via the connecting portions 51. The connecting shaft 7 must penetrate the entire height of the inner side plates 5 to ensure that adjacent inner side plates 5 can rotate relative to each other. The connecting shaft 7 passes through the connecting portions 51 of all adjacent inner side plates 5. The axial length of the connecting shaft 7 is completely consistent with the overall height of the inner side plate 5, so that the upper end face of the connecting shaft 7 is flush with the upper edge of the inner side plate 5, and the lower end face of the connecting shaft 7 is flush with the lower edge of the inner side plate 5. This through-type structure ensures that the adjacent inner side plates 5 are subjected to uniform force along the height direction when rotating around the connecting shaft 7, avoiding deformation caused by local stress concentration. When the main body unit 1 is in the fully folded and fully unfolded state, the gap between the side of the inner side plate 5 and the connecting shaft 7 forms an anti-interference area, ensuring that there is no mechanical interference between the connecting part 51 and the connecting shaft 7 when the inner side plate 5 is rotated to the fully folded or fully unfolded state. The connecting shaft 7 has a rotating shaft inside, which can rotate.

[0032] The plate has an inner wall portion, an outer wall portion, and two side portions. The combustion chamber is composed of several chambers formed inward from the inner wall portions. The outer wall portion serves as the outer boundary of the outer plate 6, directly contacting the external environment. The side portions are located at the two side edges of the plate, serving a connecting and defining function. To achieve a stable connection between the inner side plate 5 and the outer side plate 6, several through threaded holes are provided on the inner side plate 5. The barrier 61 is hollow inside. The inner side plate 5 is bolted to its corresponding barrier 61 on the outer side plate 6, with the inner and outer plates corresponding one-to-one to ensure accurate connection. The inner side plate 5 is connected to its corresponding barrier 61 on the outer side plate 6 by bolts, with the inner and outer plates corresponding one-to-one. Bolted connections offer advantages such as high connection strength and good stability. During the use of a wood-burning stove, it is subjected to various forces, such as the impact of airflow generated during combustion and vibrations during movement. The bolted connection ensures that the inner side plate 5 and the outer side plate 6 remain tightly connected under these forces, preventing loosening or separation, thus guaranteeing the stability and reliability of the overall structure of the wood-burning stove. At the same time, the bolted connection facilitates disassembly and assembly. When cleaning, repairing, or replacing parts of the wood-burning stove is required, the user can easily separate the inner side plate 5 and the outer side plate 6 by removing the bolts, greatly improving the convenience of maintenance.

[0033] like Figures 1 to 9As shown, the top plate 2 is disposed on the upper part of the main body unit 1 and is detachably connected to the main body unit 1. The upper part of the top plate 2 is provided with a support platform 21 for supporting the object to be heated. The upper part of the top plate 2 is provided with an opening, through which the object to be heated is placed into the support platform 21 for heating. The bottom of the top plate 2 is provided with an installation area, through which the top plate 2 abuts against the upper end of the main body unit 1 and is sleeved and connected. The base 3 is disposed on the lower part of the main body unit 1 and is detachably connected to the main body unit 1. The top of the base 3 is provided with a support area 32, and the lower end of the main body unit 1 abuts against the support area 32 of the base 3 and is sleeved and connected to the base 3. The top plate 2 and the base plate are both detachably connected to the main body unit 1, which is conducive to assembly and disassembly. The support area 32 also helps to improve the overall stability.

[0034] The top plate 2 has an installation area at its bottom. The top plate 2 abuts against the upper end of the main body unit 1 through the installation area and is sleeved and connected to the main body unit 1. The top plate 2 is located on the upper part of the main body unit 1 and is detachably connected to the main body unit 1. The base 3 is located on the lower part of the main body unit 1 and is detachably connected to the main body unit 1. The lower end of the main body unit 1 abuts against the support area 32 of the base 3 and is sleeved and connected to the base 3. This detachable connection design brings great convenience to the use of the wood-burning stove. This detachability not only facilitates daily use, but also extends the service life of each component of the wood-burning stove, because a component can be maintained or replaced individually as needed without scrapping the whole thing. This sleeved connection method is not only easy to install and disassemble, but also can effectively bear the weight of the items on the support platform 21 and various forces generated during combustion, ensuring the stability and reliability of the entire wood-burning stove structure.

[0035] The top plate 2 has a support surface 21 on its upper part to support the items to be heated. The support surface 21 is usually made of a material with certain strength and heat resistance, such as stainless steel or a special alloy. Its surface is finely treated, smooth and flat, providing a stable platform for various items to be heated. Whether it is a pot, kettle or other cooking utensils, they can be placed stably on the support surface 21 for heating. The size and shape of the support surface 21 are optimized according to the overall design and usage requirements of the wood-burning stove to ensure that it can meet the cooking needs of different users; the top plate 2 has an opening at its upper part, through which the items to be heated are placed into the support surface 21 for heating.

[0036] like Figures 1 to 9As shown, the upper and lower ends of the main body unit 1 are set as open structures. The upper end, hollow cavity and lower end of the main body unit 1 are interconnected. The upper and lower openings are conducive to storage after folding. When the main body unit 1 is fully folded, the internal hollow cavity forms a first storage chamber. When the main body unit 1 is fully folded, the top plate 2 and the base 3 are removed from the main body unit 1 and placed into the first storage chamber through the open structure. At this time, the outer wall of the main body unit 1 abuts against the supporting medium.

[0037] like Figures 1 to 9 As shown, when the main unit 1 is fully unfolded, the top plate 2 rests against the upper part of the main unit 1, and the base 3 rests against the lower part of the main unit 1, thus forming a furnace. The furnace rests against the supporting medium through the supporting device 4. The combustible material is placed in the second storage chamber through the opening of the top plate 2 or the opening structure of the main unit 1. After the combustible material is placed in the supporting area 32 on the base plate and ignited, the second storage chamber serves as a space for holding the combustible material to burn, providing sufficient combustion space, stabilizing the combustion environment, and improving the combustion effect.

[0038] The upper, hollow, and lower ends of the main unit 1 are interconnected, forming a continuous spatial channel. When the main unit 1 is fully folded, its internal hollow chamber cleverly transforms into the first storage compartment. During the folding process, the top plate 2 and base 3 are first removed from the main unit 1. Due to the open structure of the main unit 1, the removed top plate 2 and base 3 can be easily placed into the first storage compartment through the openings. At this time, the outer wall of the main unit 1 rests against a supporting medium, which can be of various types, providing a stable support base for the folded storage state of the main unit 1. This folding and storage method greatly saves space, making it very convenient to store the wood stove in a backpack or suitcase for outdoor travel, or to store it in a warehouse or corner of the home, thus improving space utilization. Burnable materials can be placed in the second storage compartment through the opening of the top plate 2 or the opening structure of the main unit 1. The opening on the top plate 2 is cleverly designed, making it easy for users to put in burnable materials and also facilitating the addition of new burnable materials during the burning process.

[0039] After the combustible material is placed on the support area 32 on the chassis and ignited, the second storage chamber takes on the crucial role of holding the combustible material for combustion. It provides a relatively independent and well-designed space for combustion, allowing the combustible material to fully contact the air and promoting the combustion reaction. This stable combustion environment is thanks to the rational structural design of the main unit 1, top plate 2, and base 3, which reduces interference from external factors such as wind and dust, enabling the flame to burn continuously and stably. This stable combustion environment helps improve combustion efficiency, making combustion more complete, reducing the production of smoke and harmful gases, and releasing more heat, providing users with a more efficient and stable heat source to meet various needs such as outdoor cooking and heating.

[0040] like Figures 1 to 9 As shown, the support device 4 of the wood-burning stove is located below the base 3. When needed, the support device 4 is opened and placed on the ground, playing a crucial role in stabilizing the entire stove. The support device 4 typically consists of multiple support legs, which can be made of metal, such as stainless steel or cast iron, to ensure sufficient strength and durability to support the weight of the wood-burning stove and its internal combustion materials. By setting up the components, excessive wear on the ground or other contact surfaces is prevented when moving or placing the wood-burning stove, increasing friction with the ground and preventing the stove from slipping due to external forces during use. A ventilation area is formed between the bottom of the support device 4 and the bottom of the base 3. The bottom of the base 3 is provided with several evenly distributed air inlets. The ventilation area and the air inlets are interconnected to form an air intake channel for the complete combustion of the firewood in the stove. Through the direct contact between the elevated main unit 1 and the ground, as well as the setting of the ventilation area and air inlets, sufficient oxygen can be provided to promote complete combustion of the firewood. Good air circulation and complete combustion can create a relatively stable combustion environment and prevent overheating.

[0041] like Figures 1 to 9As shown, the circumferential area of ​​the inner wall of the inner side plate 5 forms an enclosure, enclosing the combustible material and providing a relatively concentrated space for combustion; the core of ventilation lies in the design of the secondary heating channel. The lower side wall of the outer side plate 6 has a lower secondary air inlet 62, and the upper side wall of the inner side plate 5 has an upper secondary air inlet 52. Together with the heat-insulating area, these two constitute the secondary heating channel of the combustion-supporting stove. During combustion, primary air intake only supplies oxygen to the combustible material from the bottom. As combustion progresses, the oxygen in the upper layer of the furnace is gradually depleted, resulting in incomplete combustion of the upper layer of firewood. At this time, air enters from the lower secondary air inlet 62 at the bottom of the outer side plate 6, and is heated during its flow in the heat-insulating area. The heated air is less likely to lower the temperature of the flue gas, thus reducing the minimum combustible concentration of the flue gas. The hot air then enters the combustion zone through the upper secondary air inlet 52 at the top of the inner side plate 5, replenishing the oxygen lacking in the upper layer, allowing the upper layer of firewood to burn completely and increasing fuel combustion efficiency.
