Description

Technical Field

[0001] This invention relates to stoves, and more particularly to a multifunctional, safe, energy-saving, environmentally friendly, and portable outdoor stove. Background Technology

[0002] As people's living standards improve, more and more people are enthusiastic about outdoor activities, such as courtyard gatherings, long-distance road trips, mountain climbing and skiing, and camping. However, when camping and dining outdoors, the use of outdoor stoves and cookware is affected by factors such as safety, energy conservation and environmental protection, portability, durability, and operability. Therefore, most outdoor stoves and cookware on the market can only be used for simple grilling or cooking simple staple foods, which is insufficient to meet the needs of different people. At the same time, there is no very good way to keep warm outdoors. In addition, wood-burning stoves are heavy and not very convenient to move. Therefore, how to create an atmosphere for outdoor activities, cook freely, and keep warm during night camping without carrying too many stoves and cookware, and how to make wood-burning stoves easier to transport, store, and move, has become a problem.

[0003] In addition, when cleaning the ash from existing stoves, the stoves need to be turned over and the ash poured out from the stove opening, which is time-consuming, laborious, and causes a lot of inconvenience. Summary of the Invention

[0004] To address the aforementioned issues, the present invention aims to provide a multifunctional, safe, energy-saving, environmentally friendly, and portable outdoor stove. This outdoor stove is designed in the shape of a suitcase, making it extremely convenient to move. Furthermore, it is collapsible, reducing its volume by nearly one-third for easy storage and carrying. In addition, this outdoor stove can also have multiple functions depending on the usage scenario and needs, such as being used as a campfire stove, a cooking boiler, or a heating stove.

[0005] To achieve the above objectives, the present invention adopts the following technical solution: a furnace body with an opening at the top, a furnace cavity is provided inside the furnace body, a combustion chamber is formed in the furnace cavity, and a grid plate is provided at the lower end of the combustion chamber;

[0006] The furnace body includes an outer furnace wall and an inner furnace wall. The outer furnace wall includes a lower outer furnace wall and an upper outer furnace wall whose lower end is sleeved on the upper end of the lower outer furnace wall. The inner furnace wall includes an upper inner furnace wall and a lower inner furnace wall whose upper end overlaps the lower end of the upper inner furnace wall. The upper end of the upper inner furnace wall extends outward to form an end edge, and the end edge is closed and connected to the upper end of the upper outer furnace wall.

[0007] A furnace trough is mounted on the end edge, and a first air inlet channel is opened on the side wall of the furnace trough and communicates with the furnace cavity. A positioning step is provided circumferentially at the upper end of the furnace trough, and a baking rack is mounted on the positioning step. The baking rack has a mounting opening in the middle. The bottom end of the furnace trough is recessed upward to form a boss, and the upper end of the boss abuts against the lower end face of the mounting opening. A central hole is opened in the middle of the boss and corresponds to the mounting opening.

[0008] The side wall of the boss is provided with a second air intake channel and communicates with the furnace cavity. The mounting opening is covered with a cover plate, and the cover plate is provided with a pot.

[0009] The furnace trough is covered with a furnace cover to cover the opening of the furnace trough. A handle is fixedly provided at the upper end of the furnace cover. A protrusion extends upward from the upper end of the furnace cover. Multiple ventilation holes are radially opened on the upper surface of the protrusion.

[0010] In the aforementioned technical solution, the stove body consists of inner and outer double-layered walls, which are further divided into an interlocking upper and lower outer wall, and an overlapping upper and lower inner wall, facilitating subsequent storage and use. The stove opening is equipped with a grill slot, a grill rack, a lid, and cookware, enabling functions such as frying, steaming, boiling, stir-frying, grilling, and teppanyaki. For outdoor campers, there's no need to carry extra pots, pans, grills, or other cooking utensils; simply carrying this outdoor stove allows them to enjoy various cooking methods, meeting their needs. Furthermore, the lid provides rain protection, keeping the interior of the stove dry and facilitating continuous use. Additionally, by removing the grill slot, grill rack, lid, and cookware from the stove opening, the stove can be used as a campfire stove, satisfying users' outdoor entertainment needs and achieving multi-functionality.

[0011] Preferably, the furnace trough is frustoconical, with its inner diameter gradually decreasing from top to bottom. The first air intake channel includes multiple first airflow holes circumferentially arranged on the side wall of the furnace trough. The boss is frustoconical, with its outer diameter gradually increasing from top to bottom. The second air intake channel includes second airflow holes circumferentially arranged on the side wall of the boss. The lower end of the cover plate is provided with multiple baffles extending downward into the mesh surface of the baking rack. In this technical solution, since both the furnace trough and the boss are frustoconical, the first and second air intake channels are obliquely arranged and aligned with the baking rack, allowing for all-around hot air supply to the baking rack. Furthermore, the cover plate facilitates adjustment of heat concentration or release at the central hole and provides a support surface. The baffles at the lower end of the cover plate prevent the cover plate from detaching laterally from the baking rack during use and transportation.

[0012] Preferably, a gap is provided between the outer furnace wall and the inner furnace wall, the lower end of the outer furnace wall is lower than the lower end of the inner furnace wall, an air inlet is provided on the lower end face of the inner furnace wall, a third air inlet channel is provided on the upper end of the inner furnace wall, and a fourth air inlet channel is provided on the lower end of the outer furnace wall. The third air inlet channel communicates with the fourth air inlet channel through the gap, and the fourth air inlet channel communicates with the air inlet. In this technical solution, air enters the furnace body through the fourth air inlet channel, and part of it enters the upper third air inlet channel through the gap, and then enters the combustion chamber. Since both the third and fourth air inlet channels are composed of multiple airflow holes evenly arranged circumferentially, the air enters the combustion chamber evenly from the upper periphery, which can make the combustion more complete. The other part of the air enters the furnace body through the air inlet, which can keep the air in the furnace body circulating smoothly and prevent the furnace temperature from becoming too high.

[0013] Preferably, the combustion chamber includes an upper combustion chamber and a lower combustion chamber, the lower inner furnace wall includes a rim and a ventilation plate, the lower combustion chamber is located in the lower inner furnace wall, the rim is provided on the periphery of the lower combustion chamber, the edge of the grating plate extends downward in the circumferential direction to provide a side wall, the inner side and the outer side of the side wall are respectively fixedly connected to the upper outer wall of the ventilation plate and the lower inner wall of the lower inner furnace wall;

[0014] The air inlet is located at the bottom center of the ventilation plate; a ash receiving tray is provided inside the ventilation plate and below the grid plate. Multiple support legs are fixedly provided on the peripheral wall of the ash receiving tray. The lower end of the support legs is fixedly connected to the upper bottom of the ventilation plate. The side wall of the ash receiving tray is provided with gaps between itself and the side wall and bottom of the ventilation plate.

[0015] In this technical solution, the sidewalls make the connection of the grating plates more stable; and the gaps between the sidewalls of the ash receiving pan and the sidewalls and bottom of the ventilation pan allow air to enter the ventilation pan and be blocked by the ash receiving pan, thus spreading out and passing between the sidewalls of the ash receiving pan and the inner wall of the ventilation pan to reach the grating plate, so that the fuel can achieve uniform and complete combustion.

[0016] Preferably, the grating plate is a single piece and is recessed into an arch shape towards the opening of the furnace body; the grating plate has grating holes; the surface of the grating plate is provided with first reinforcing ribs, which are distributed circumferentially and radially; multiple handles are fixedly provided at the upper end of the grating. In this technical solution, the first reinforcing ribs greatly increase the strength of the grating plate, making it extremely difficult to collapse, and the fact that the grating plate is a single piece and has an arch shape is also to prevent the grating plate from collapsing, which can improve the service life of the furnace. In addition, the handles on the grating plate allow the user to easily remove the lower inner furnace wall from the furnace body by simply grabbing the handles and pulling upwards when the furnace body is in the retracted state, which is extremely convenient for emptying ash, saving time and effort.

[0017] Preferably, the lower outer wall of the upper outer furnace wall is provided with a second reinforcing rib in the circumferential direction, and the upper end of the lower outer furnace wall is provided with a second circular arc edge in the circumferential direction; the inner diameter of the lower outer furnace wall is larger than the outer diameter of the upper outer furnace wall.

[0018] The upper end of the lower outer furnace wall is fitted onto the lower end of the upper outer furnace wall, so that the lower end face of the second reinforcing rib abuts against the upper end face of the second circular arc edge. At this time, the furnace body is in an unfolded state.

[0019] The upper opening of the lower outer furnace wall can be fitted onto the outer side of the upper outer furnace wall along the upper end of the upper outer furnace wall so that the upper end face of the second circular arc edge abuts against the upper end face of the second reinforcing rib. At this time, the furnace body is in a retracted state.

[0020] In the above technical solution, when the furnace body is in the unfolded state, the second circular arc edge abuts against the lower end of the second reinforcing rib. Since the lower end of the upper outer furnace wall extends into the upper end of the lower outer furnace wall, it can effectively prevent the outer furnace wall from separating laterally and longitudinally. Moreover, the abutting surface is an arc surface, which can reduce wear between the two. In addition, the inner diameter formed by the second circular arc edge is smaller than the outer diameter formed by the second reinforcing rib. Therefore, when the lower outer furnace wall is fitted onto the outer side of the outer furnace wall, the second circular arc edge abuts against the upper end of the second reinforcing rib, thereby preventing the lower outer furnace wall from separating longitudinally when fitted onto the outer side of the outer furnace wall.

[0021] Preferably, the lower end of the upper inner furnace wall is provided with a fourth circular arc edge inward in the circumferential direction, and the upper end of the lower inner furnace wall is provided with an arched arc edge in the circumferential direction. The outer diameter of the lower inner furnace wall is smaller than the inner diameter of the upper inner furnace wall. The lower inner furnace wall can pass through the upper inner furnace wall through the upper opening and extend from the lower end of the upper inner furnace wall so that the arched arc edge rests on the fourth circular arc edge. The lower end of the upper outer furnace wall is provided with a first circular arc edge inward in the circumferential direction, and the lower end of the first circular arc edge is flush with the lower end of the fourth circular arc edge. In this technical solution, since the arched edge is only placed on the fourth circular arc edge, during the storage process, simply lift the upper outer furnace wall and then take out the lower outer furnace wall. The upper outer furnace wall and the upper inner furnace wall will then fall naturally, so that the lower inner furnace wall is inside the upper inner furnace wall. This can be used as a fire pit for convenient heating at night. Furthermore, the upper furnace cover can be inverted and stored inside the retracted furnace body, which greatly saves storage space. In this stored state, it is easy to transport and store.

[0022] In addition, the arched edge can be attached to the fourth circular arc edge, which prevents the lower inner furnace wall from falling from below when the upper outer furnace body is being installed, thus avoiding damage to the lower inner furnace wall. Furthermore, this design ensures the integrity of the furnace body even without a fixed connection, facilitating the separation of the upper and lower outer furnace walls.

[0023] The first circular arc edge allows the furnace body to be supported together with the fourth circular arc edge when it is in the storage state, making the furnace body more stable. The arc surface in contact with the ground can protect the ground and furnace wall from wear.

[0024] Preferably, the lower end of the outer furnace wall is provided with a third circular arc edge circumferentially outward;

[0025] Multiple foot pads are fixedly provided circumferentially at the lower end of the inner furnace wall;

[0026] When the furnace body is in the unfolded state, the lower outer furnace wall is supported at the lower end of the upper outer furnace wall, and the lower inner furnace wall is suspended at the lower end of the upper inner furnace wall.

[0027] When the furnace body is in the retracted state, the lower outer furnace wall is installed outside the upper outer furnace wall, the lower inner furnace wall is inside the upper inner furnace wall, and the foot pads support the furnace body.

[0028] In the above technical solution, when the furnace body is in the retracted state, the third circular arc edge, together with the foot pads, supports the furnace body, increasing the contact area between the furnace body and the ground, making the furnace body more stable, and ensuring that the contact surface between the furnace wall and the ground is curved, preventing damage to the ground. Furthermore, the foot pads ensure smooth airflow at the bottom of the furnace body, preventing excessive temperature rise; additionally, when removing the lower inner furnace wall to empty the ash, the foot pads prevent the lower inner furnace wall from contacting the ground.

[0029] Preferably, the lower outer wall of the lower furnace wall is provided with multiple positioning seats circumferentially, and a support frame is hinged to the positioning seat. The support frame is square ring-shaped, with at least two support frames having their lower ends inclined outwards and at least two support frames having their lower ends bent inwards to form a bending frame. A caster is provided at the lower end of the bending frame, and the bottom end of the caster is flush with the bottom end of the support frame. The support frame with its lower end inclined outwards can cooperate with the caster to support the furnace body and lock it on a horizontal plane. The lower outer wall of the lower furnace wall is also fixedly provided with a fixing seat, and the fixing seat is connected to a telescopic pull rod.

[0030] There are two fixed seats. The pull rod includes a fourth telescopic rod that is inserted into the fixed seat, and a third telescopic rod, a second telescopic rod and a first telescopic rod that can be telescopically connected from bottom to top. The upper ends of the first telescopic rods on both sides are fixedly connected by an arc-shaped pull handle.

[0031] The pull rod is in an extended state, and the upper end of the pull rod is higher than the upper end of the furnace body;

[0032] The pull rod is in a retracted state, and the upper end of the pull rod is lower than the upper end of the outer furnace wall.

[0033] In the aforementioned technical solution, a pull rod and casters are installed on the outside of the furnace body, giving it an overall suitcase-like appearance. When in use, the casters and support frames are both supported at the lower end of the furnace body, with at least two support frames ensuring the furnace body remains stable. To move the furnace body, rotate the two support frames that allow the furnace body to stand upright until they are flush against the outer wall of the furnace body. At this point, only the casters are on the ground, allowing the furnace body to be unlocked and moved. The pull rod can be retracted downwards to below the upper part of the lower outer furnace wall, without affecting the normal use of the furnace. Extending the pull rod allows for easy movement of the furnace body, which is very convenient. Furthermore, the support frames can elevate the furnace body as much as possible for user convenience and allow for greater airflow at the bottom of the furnace body.

[0034] Preferably, the handle is covered with a heat-resistant rubber layer, and the heat-resistant rubber layer is provided with multiple anti-slip rings.

[0035] The lower edge of the furnace cover is provided with a fifth circular arc edge circumferentially downward, and the fifth circular arc edge abuts against the upper outer wall of the upper outer furnace wall;

[0036] A barrier cover is fastened to the outer side of the protrusion. Multiple adjustment holes are radially opened at the upper end of the barrier cover, corresponding to the ventilation holes. A rotating shaft is riveted to the middle of the barrier cover. The lower end of the rotating shaft is fixedly connected to the protrusion. An adjustment handle is fixedly provided on the side wall of the barrier cover. The adjustment handle can drive the barrier cover to rotate relative to the protrusion under the action of external force.

[0037] A thermometer is provided at the upper end of the furnace cover. The probe of the thermometer extends into the inside of the furnace cover. When the furnace cover covers the furnace trough, the thermometer is used to detect the temperature inside the furnace cover.

[0038] The outdoor stove also includes a fire-gathering ring, which includes an annular support plate and an arched ring wall extending upward along the inner wall of the support plate. The upper center of the arched ring wall has a through hole communicating with the furnace cavity. When the outdoor stove does not use the furnace trough and furnace cover, the fire-gathering ring is mounted on the end edge.

[0039] In the above technical solution, the anti-scalding rubber layer serves to prevent scalding, while the anti-slip ring makes it easier for users to grip the handle.

[0040] The fifth circular arc edge ensures the oven lid stays securely on the outer side of the upper outer oven wall, maintaining airtightness during cooking and preventing lateral detachment during use and transportation. A thermometer measures the temperature inside the oven lid; heating temperature is particularly important when steaming buns and preparing meat products. As a cooking utensil, attention to detail is crucial. The barrier cover can be rotated and positioned outside the vent, allowing the adjustment hole to be aligned with or offset from the vent to regulate the temperature inside the oven lid.

[0041] When the stove is used as a campfire, the fire-collecting ring is placed on the end rim to prevent the flames from spreading. Furthermore, when the stove is stored and used as a brazier, the fire-collecting ring is also necessary. Attached Figure Description

[0063] like Figures 1-16 The invention relates to a multifunctional, safe, energy-saving, environmentally friendly, and portable outdoor stove, which includes a stove body 1 with an opening at the top, a stove cavity inside the stove body 1, a combustion chamber formed in the stove cavity, and a grid plate 2 at the lower end of the combustion chamber.

[0064] The furnace body 1 includes an outer furnace wall and an inner furnace wall. The outer furnace wall includes a lower outer furnace wall 3 and an upper outer furnace wall 4 whose lower end is sleeved on the upper end of the lower outer furnace wall 3. The inner furnace wall includes an upper inner furnace wall 5 and a lower inner furnace wall 6 whose upper end overlaps the lower end of the upper inner furnace wall 5. The upper end of the upper inner furnace wall 5 extends outward to form an end edge 7, and the end edge 7 is closed and connected to the upper end of the upper outer furnace wall 4.

[0065] A furnace trough 8 is mounted on the end edge 7. A first air inlet channel 9 is provided on the side wall of the furnace trough 8 and communicates with the furnace cavity. A positioning step 10 is provided circumferentially at the upper end of the furnace trough 8. A baking rack 11 is mounted on the positioning step 10. A mounting opening 12 is provided in the middle of the baking rack 11. A boss 13 is formed by an upward indentation in the middle of the bottom end of the furnace trough 8. The upper end of the boss 13 abuts against the lower end face of the mounting opening 12. A central hole 14 is provided in the middle of the boss 13 and corresponds to the mounting opening 12.

[0066] The side wall of the boss 13 is provided with a second air intake channel 15 and communicates with the furnace cavity. The mounting opening 12 is covered with a cover plate 16, and a pot is provided on the cover plate 16.

[0067] The furnace trough 8 is covered by a furnace cover 17 to cover the opening of the furnace trough 8. A handle 18 is fixedly provided at the upper end of the furnace cover 17. A protrusion 19 extends upward from the upper end of the furnace cover 17. A plurality of ventilation holes 20 are radially opened on the upper surface of the protrusion 19.

[0068] In the above technical solution, the stove body 1 consists of inner and outer double-layered walls, which are further divided into an upper outer wall 4 and a lower outer wall 3 that fit together, and an upper inner wall 5 and a lower inner wall 6 that overlap, facilitating subsequent storage and use. The opening of the stove body 1 is equipped with a stove slot 8, a grill rack 11, a cover plate 16, and cookware, enabling functions such as frying, steaming, boiling, stir-frying, grilling, and teppanyaki. For outdoor campers, there is no need to carry extra pots, pans, grills, or other cooking utensils; simply carrying this outdoor stove allows them to enjoy various cooking methods, meeting their needs. Furthermore, the stove cover 17 provides rain protection, keeping the inside of the stove dry and facilitating continuous use. Additionally, by removing the stove slot, grill rack, cover plate, and cookware from the opening, the stove body 1 can be used as a campfire stove, meeting the user's outdoor entertainment needs and thus achieving a multi-functional stove.

[0069] The specific operation and features of this outdoor stove are as follows:

[0070] 1. The stove body and fire-gathering ring are designed to be used as a campfire stove when the stove body is unfolded. It features safety, high heat output, low smoke, portability, and easy cleaning. It can be used in courtyards and outdoors. The fuel used is firewood.

[0071] 2. The stove body and fire-concentrating ring are designed for storage and can be used as a fire basin. It features safety, anti-scalding, heat preservation, and smokelessness, and can be used indoors in well-ventilated conditions. The fuel used is charcoal.

[0072] 3. The furnace body, fire-concentrating ring, and furnace cover can prevent rain when placed outdoors (or on a terrace), protecting the interior of the furnace from rainwater.

[0073] 4. The oven body, oven trough, and grill rack can be used as a smokeless barbecue grill or a high-powered hot pot stove: no water is added to the oven trough, and a wok or soup pot can be placed on the cover. It features safety, energy saving, smokelessness, excellent thermal efficiency, and prevents moisture or oil from seeping out of the food during grilling from coming into contact with the charcoal fire; the fuel used is charcoal or firewood.

[0074] 5. The oven body, oven trough, grill rack, and oven lid can be used as a simmering oven. Water is added to the oven trough, and spices or food can be added to the water. The food on the grill rack is cooked by a combination of simmering and steaming under the interaction of the water vapor coming out of the oven trough and the heat energy of the charcoal at the central hole. The aroma of the spices in the boiling water enters the food through the steam and is enhanced by charcoal grilling. The fuel used is charcoal.

[0075] 6. The furnace body, furnace trough, grill rack, and cover can be used for steaming, boiling, and stir-frying. Water can be added to the furnace trough (for direct hot pot), and charcoal can be added to the center hole. The grill rack with the cover can be used as a steamer. A wok or soup pot can be placed on the cover. The fuel used is charcoal or firewood.

[0076] Furthermore, the furnace trough 8 is frustoconical, and its inner diameter gradually decreases from top to bottom. The first air intake channel 9 includes multiple first airflow holes circumferentially arranged on the side wall of the furnace trough 8. The boss 13 is frustoconical, and its outer diameter gradually increases from top to bottom. The second air intake channel 15 includes second airflow holes circumferentially arranged on the side wall of the boss 13. The lower end of the cover plate 16 is provided with multiple baffles 21 that extend downward into the mesh surface of the grill rack 11. In this technical solution, since both the furnace trough 8 and the boss 13 are frustoconical, the first and second air intake channels are obliquely arranged and aligned with the grill rack, allowing for all-around hot air supply to the grill rack. In addition, the cover plate facilitates the adjustment of heat concentration or release at the central hole and provides a support surface. The baffles at the lower end of the cover plate are to prevent the cover plate from detaching laterally from the grill rack 11 during use and transportation.

[0077] Furthermore, a gap is provided between the outer furnace wall and the inner furnace wall. The lower end of the outer furnace wall is lower than the lower end of the inner furnace wall. An air inlet 22 is provided on the lower end face of the inner furnace wall. A third air inlet channel 23 is provided on the upper end of the inner furnace wall, and a fourth air inlet channel 24 is provided on the lower end of the outer furnace wall. The third air inlet channel 23 communicates with the fourth air inlet channel 24 through the gap, and the fourth air inlet channel 24 communicates with the air inlet 22. In this technical solution, air enters the furnace body 1 through the fourth air inlet channel 24, and part of it enters the upper third air inlet channel 23 through the gap, and then enters the combustion chamber. Since both the third air inlet channel 23 and the fourth air inlet channel 24 are composed of multiple airflow holes evenly arranged circumferentially, the air enters the combustion chamber evenly from the upper periphery, which can make the combustion more complete. The other part of the air enters the furnace body through the air inlet, which can keep the air in the furnace body circulating smoothly and prevent the furnace temperature from becoming too high.

[0078] Furthermore, the combustion chamber includes an upper combustion chamber and a lower combustion chamber. The lower inner furnace wall 6 includes a rim 25 and a ventilation plate 26. The lower combustion chamber is located in the lower inner furnace wall 6. The rim 25 is disposed on the periphery of the lower combustion chamber. The edge of the grid plate 2 extends downward in the circumferential direction and is provided with a side wall 27. The inner and outer sides of the side wall 27 are respectively fixedly connected to the upper outer wall of the ventilation plate 26 and the lower inner wall of the lower inner furnace wall 6.

[0079] The air inlet 22 is located at the bottom center of the ventilation plate 26; a ash receiving plate 28 is provided inside the ventilation plate 26 and below the grid plate 2. A plurality of support legs 29 are fixedly provided on the peripheral wall of the ash receiving plate 28. The lower end of the support legs 29 is fixedly connected to the upper bottom of the ventilation plate 26. A gap is provided between the side wall of the ash receiving plate 28 and the side wall and bottom of the ventilation plate 26, respectively.

[0080] In this technical solution, the side wall 27 makes the connection of the grid plate 2 more stable; and the gaps between the side wall of the ash receiving pan 28 and the side wall and bottom of the ventilation pan 26 respectively allow the air to enter the ventilation pan and be blocked by the ash receiving pan, so that it spreads out and passes between the side wall of the ash receiving pan 28 and the inner wall of the ventilation pan 26 to reach the grid plate 2, so that the fuel can achieve uniform and complete combustion.

[0081] Furthermore, the grating plate 2 is a single piece of plate and is recessed into an arch shape towards the opening of the furnace body 1; the grating plate 2 is provided with grating holes; the surface of the grating plate 2 is provided with first reinforcing ribs 30, which are distributed circumferentially and radially; multiple handles 31 are fixedly provided at the upper end of the grating. In this technical solution, the first reinforcing ribs 30 greatly increase the strength of the grating plate 2, making it extremely difficult to collapse, and the grating plate 2 being a single piece of plate with an arch shape is also to prevent the grating plate from collapsing, which can improve the service life of the furnace. In addition, the handles 31 on the grating plate 2 can be used to easily remove the lower inner furnace wall from the furnace body by simply grabbing the handle and pulling upwards when the furnace body is in the retracted state, which is extremely convenient for emptying ash, saving time and effort.

[0082] Furthermore, the lower outer wall of the upper outer furnace wall 4 is provided with a second reinforcing rib 32 in the circumferential direction, and the upper end of the lower outer furnace wall 3 is provided with a second circular arc edge 33 in the circumferential direction; the inner diameter of the lower outer furnace wall 3 is larger than the outer diameter of the upper outer furnace wall 4.

[0083] The upper end of the lower outer furnace wall 3 is fitted onto the lower end of the upper outer furnace wall 4, so that the lower end face of the second reinforcing rib 32 abuts against the upper end face of the second circular arc edge 33. At this time, the furnace body 1 is in an unfolded state.

[0084] The upper opening of the lower outer furnace wall 3 can be fitted onto the outer side of the upper outer furnace wall 4 along the upper end of the upper outer furnace wall 4 so that the upper end face of the second circular arc edge 33 abuts against the upper end face of the second reinforcing rib 32. At this time, the furnace body 1 is in a retracted state.

[0085] In the above technical solution, when the furnace body 1 is in the unfolded state, the second circular arc edge 33 abuts against the lower end of the second reinforcing rib 32. Since the lower end of the upper outer furnace wall 4 extends into the upper end of the lower outer furnace wall 3, it can effectively prevent the outer furnace wall from separating laterally and longitudinally. Moreover, the abutting surface is an arc surface, which can reduce the wear between the two. In addition, the inner diameter formed by the second circular arc edge is smaller than the outer diameter formed by the second reinforcing rib 32. Therefore, when the lower outer furnace wall is fitted on the outside of the outer furnace wall, the second circular arc edge abuts against the upper end of the second reinforcing rib 32, thereby preventing the lower outer furnace wall from separating longitudinally when fitted on the outside of the outer furnace wall.

[0086] Furthermore, the lower end of the upper inner furnace wall 5 is provided with a fourth circular arc edge 34 circumferentially inward, and the upper end of the lower inner furnace wall 6 is provided with an arched arc edge 35 circumferentially outward. The outer diameter of the lower inner furnace wall 6 is smaller than the inner diameter of the upper inner furnace wall 5. The lower inner furnace wall 6 can pass through the upper inner furnace wall 5 through the upper opening and extend from the lower end of the upper inner furnace wall 5 so that the arched arc edge 35 rests on the fourth circular arc edge 34. The lower end of the upper outer furnace wall 4 is provided with a first circular arc edge 36 circumferentially inward, and the lower end of the first circular arc edge 36 is flush with the lower end of the fourth circular arc edge 34. In this technical solution, since the arched arc edge 35 is only placed on the fourth circular arc edge 34, during the storage process, simply lift the upper outer furnace wall and then take out the lower outer furnace wall. The upper outer furnace wall and the upper inner furnace wall will then fall naturally, so that the lower inner furnace wall is inside the upper inner furnace wall. This can be used as a fire pit for convenient heating at night. Furthermore, the upper furnace cover can be inverted and stored inside the retracted furnace body, which greatly saves storage space. In this stored state, it is easy to transport and store.

[0087] Furthermore, a third circular arc edge 37 is provided circumferentially outward at the lower end of the lower outer furnace wall 3;

[0088] Multiple foot pads 38 are fixedly provided circumferentially at the lower end of the inner furnace wall 6;

[0089] When the furnace body 1 is in the unfolded state, the lower outer furnace wall 3 is supported on the lower end of the upper outer furnace wall 4, and the lower end of the foot pad 38 is flush with the lower end of the outer furnace wall.

[0090] When the furnace body 1 is in the retracted state, the lower outer furnace wall 3 covers the outside of the upper outer furnace wall 4, the lower inner furnace wall 6 is inside the upper inner furnace wall 5, and the foot pads 38 are supported on the furnace body 1.

[0091] In the above technical solution, when the furnace body is in the retracted state, the third circular arc edge, together with the foot pads, supports the furnace body, increasing the contact area between the furnace body and the ground, making the furnace body more stable, and ensuring that the contact surface between the furnace wall and the ground is curved, preventing damage to the ground. Furthermore, the foot pads ensure smooth airflow at the bottom of the furnace body, preventing excessive temperature rise; additionally, when removing the lower inner furnace wall to empty the ash, the foot pads prevent the lower inner furnace wall from contacting the ground.

[0092] Furthermore, the lower outer wall of the lower furnace wall 3 is provided with a plurality of positioning seats 39 circumferentially on the lower part of the outer wall. A support frame 40 is hinged to the positioning seat 39. The support frame 40 is in the shape of a square ring. At least two of the support frames 40 are inclined outward at their lower ends, and at least two of the support frames 40 are bent inward at their lower ends to form a bending frame. A caster wheel 42 is provided at the lower end of the bending frame. The bottom end of the caster wheel 42 is flush with the bottom end of the support frame 40. The support frame 40 with its lower end inclined outward can cooperate with the caster wheel 42 to support the furnace body and lock it on the horizontal plane. A fixing seat 43 is also fixedly provided on the lower part of the outer wall of the lower outer furnace wall 3. The fixing seat 43 is connected to a telescopic pull rod 100.

[0093] There are two fixed seats 43. The pull rod 100 includes a fourth telescopic rod 44 that is inserted into the fixed seat 43, and a third telescopic rod 45, a second telescopic rod 60 and a first telescopic rod 61 that can be telescopically connected from bottom to top. The upper ends of the first telescopic rods 61 on both sides are fixedly connected by an arc-shaped pull handle 62.

[0094] The pull rod 100 is in an extended state, and the upper end of the pull rod 100 is higher than the upper end of the furnace body 1;

[0095] The pull rod 100 is in a retracted state, and the upper end of the pull rod 100 is lower than the upper end of the upper outer furnace wall 4.

[0096] In the above technical solution, a pull rod and casters are installed on the outside of the furnace body, giving it a suitcase-like appearance. When using the furnace body, the casters 42 and support frames 40 are both supported at the lower end of the furnace body, and at least two support frames 10 ensure the furnace body stands stably. When the furnace body needs to be moved, the two support frames that allow the furnace body to stand upright are rotated to fit against the outer wall of the furnace body. At this point, only the casters 42 are on the ground, allowing the furnace body to be unlocked and moved. The pull rod 100 can be retracted downwards to below the upper part of the lower outer furnace wall, without affecting the normal use of the furnace. When the furnace needs to be moved, extending the pull rod 100 allows for easy movement of the furnace body, which is very convenient. Furthermore, the support frames 10 can raise the furnace body as high as possible for user convenience and allow more airflow to the bottom of the furnace body.

[0097] Furthermore, the handle 18 is covered with an anti-scalding rubber layer 47, and the anti-scalding rubber layer 47 is surrounded by multiple anti-slip rings 48.

[0098] The lower edge of the furnace cover 17 is provided with a fifth circular arc edge 49, which abuts against the upper outer wall of the upper outer furnace wall 4.

[0099] A barrier cover 50 is fastened to the outer side of the protrusion 19. The upper end of the barrier cover 50 has a plurality of adjustment holes 51 that correspond to the vent holes 20. A rotating shaft is riveted to the middle of the barrier cover 50. The lower end of the rotating shaft is fixedly connected to the protrusion 19. An adjustment handle 52 is fixedly provided on the side wall of the barrier cover 50. The adjustment handle 52 can drive the barrier cover 50 to rotate relative to the protrusion 19 under the action of external force.

[0100] A thermometer 53 is provided at the upper end of the furnace cover 17. The probe of the thermometer 53 extends into the interior of the furnace cover 17. When the furnace cover 17 covers the furnace trough 8, the thermometer 53 is used to detect the temperature inside the furnace cover 17.

[0101] The outdoor stove also includes a fire-gathering ring 54, which includes an annular support plate and an arched ring wall extending upward along the inner wall of the support plate. The upper center of the arched ring wall has a through hole communicating with the furnace cavity. When the outdoor stove does not use the furnace trough 8 and the furnace cover 17, the fire-gathering ring 54 is mounted on the end edge 7.

[0102] In the above technical solution, the anti-scalding rubber layer 47 serves to prevent scalding, while the anti-slip ring 48 facilitates the user's grip on the handle. The fifth circular arc edge 49 ensures that the stove lid 17 is stably fitted onto the outer side of the upper outer wall of the stove, maintaining airtightness during cooking and preventing the stove lid from detaching laterally during use and transportation. The thermometer 53 is used to measure the temperature inside the stove lid. Heating temperature is particularly important when steaming buns and preparing meat products; as a cooking utensil, attention to detail is crucial. The barrier cover 50 is rotatably mounted outside the vent, allowing the adjustment hole to be aligned with or offset from the vent to regulate the temperature inside the stove lid.

[0103] When the stove is used as a campfire, the fire-gathering ring 54 is placed on the end rim to prevent the flames inside from spreading. Furthermore, when the stove is stored and used as a heating brazier, the fire-gathering ring is also required.

[0104] In this specific embodiment, a multifunctional, safe, energy-saving, environmentally friendly, and portable outdoor stove is characterized by its practicality and user-friendliness. The invention is divided into three stages from the start of stove use: the first stage is campfire mode, the second stage is cooking mode, and the third stage is heat preservation and heating mode. The progress of these three modes can be closely integrated with outdoor activities.

[0105] When unfolded, the outdoor stove can be moved using the casters 42 at the bottom of the stove body 1. When folded, the lower inner wall 6 of the stove body 1 is retractable, and the bottom support frame and casters are foldable, with the overall folded volume being about one-third of the unfolded volume.

[0106] In this case, the fuel is completely placed inside the combustion chamber without being exposed, and the combustion flame is concentrated in the center of the furnace and is not affected by spilled burning materials or wind. The furnace cover, furnace body and foot pads are designed as a whole to prevent slipping and tipping, and have good safety performance.

[0107] The fuel used in this case can be shrubs, dead branches, leaves, and other outdoor, garden, and courtyard materials. After the stove is used, there is no residue or carbon, only a small amount of ash, which can be used as fertilizer on the spot. The outdoor stove activates its circulating air heating and combustion-aiding physical function 5 minutes after the open flame is lit, and the campfire burning effect is smokeless. During use, the ground temperature remains at normal temperature, so it will not damage the ground and will not leave any marks on the site. Except for the heat-resistant rubber layer on the stove lid, the entire stove body is made of stainless steel with no surface coating. The product itself does not produce any odor during use and has an environmentally friendly effect.

[0108] This invention requires no assembly by the user, and its windproof design makes starting a fire simple. No one is needed to tend the campfire during the burning process. The cooking assembly, stove lid, and cover are all equipped with special slots to prevent them from easily slipping or tipping over.

[0109] This invention incorporates anti-burning and anti-deformation process design for all key components, enabling the core heat to reach over 1,000 degrees Celsius without deformation of the furnace body. It can withstand prolonged intense combustion with open flame and sustained heat preservation with charcoal fire, thus meeting the needs of different users in different environments. The entire furnace is made of 304 stainless steel.
