Description

Technical Field

[0001] This utility model relates to the field of stove technology, specifically to a heating and cooking stove. Background Technology

[0002] Outdoor stoves are indispensable equipment for outdoor camping activities, satisfying both cooking needs and providing heating in cold environments, greatly enhancing the camping experience. With the diversification of camping needs, users have placed higher demands on the functional adaptability and scenario flexibility of outdoor stoves, especially hoping to flexibly switch between or use cooking and heating functions separately according to the season and usage requirements.

[0003] Chinese Patent Publication No. CN218721671U discloses an outdoor stove with natural air supply, including a stove body with a feed inlet and a combustion chamber, and an air supply heating chamber. The air supply heating chamber is disposed on one side of the combustion chamber, and the inner wall of the combustion chamber is provided with an air supply cavity. The air supply cavity is connected to the air supply heating chamber. The air supply heating chamber is provided with an air inlet and a second air supply cavity, and the air supply cavity is provided with a first air supply cavity. This outdoor stove is suitable for heating and cooking in tents, can efficiently provide natural air supply, ensures complete fuel combustion, provides sufficient heat, and is easy to disassemble, making it convenient to carry and reducing transportation costs.

[0004] However, the outdoor stoves mentioned above rely on a single combustion system to achieve both heating and cooking functions, making it impossible to independently separate and flexibly adapt the two functions. On the one hand, in summer camping scenarios, users only need the cooking function, but the combustion system of the stove will still generate a heating effect while running, resulting in excessively high temperatures in the cooking area, which not only affects the user experience but may also cause energy waste. On the other hand, in winter camping scenarios, users primarily need heating. If cooking is required temporarily, the combustion system is designed to prioritize heating, resulting in insufficient heat supply for cooking, which significantly prolongs cooking time and reduces efficiency.

[0005] Therefore, overcoming the aforementioned shortcomings has become an important issue that urgently needs to be addressed by those skilled in the art. Utility Model Content

[0006] This invention overcomes the shortcomings of the above-mentioned technologies and provides a heating and cooking stove.

[0007] To achieve the above objectives, the present invention adopts the following technical solution: A heating and cooking stove includes: a heating component 1 and a cooking component 2, and a detachable hinge structure 3 connecting the two; the heating component 1 and the cooking component 2 are connected to each other by relative rotation through the hinge structure 3 to switch different relative positions; the heating component 1 includes a first stove 11 and a heating structure 12 mounted on top of the first stove 11; the cooking component 2 includes a second stove 21.

[0008] Preferably, the heating component 1 and the cooking component 2 can be rotated relative to each other through the hinge structure to an unfolded state in which they are arranged laterally, a folded state in which they are stacked vertically, or a separated state in which they can be disassembled and used separately. When the heating component 1 and the cooking component 2 are in the unfolded state, they are arranged horizontally on the same horizontal support surface to achieve heating and cooking functions together. When the heating component 1 and the cooking component 2 are folded, they are on the same vertical support surface. The cooking component 2 is rotated to be directly below the heating component 1. The second stove 21 is in an upside-down position. The bottom of the first stove 11 is in contact with the bottom of the second stove 21, which is used to realize the heating function alone. The separated state is used to achieve heating or cooking functions independently.

[0009] Preferably, the hinge structure 3 includes a first hinge seat 31 and a second hinge seat 32; The first hinge seat 31 is connected to the outer side wall of the heating component 1, and includes a first connecting ear 311, a first connecting longitudinal shaft 312 and a first bushing structure 313. The first connecting ear 311 is connected to the outer side wall of the first stove 11. The second hinge seat 32 is connected to the outer wall of the cooking component 2, and includes a second connecting ear 321, a second connecting longitudinal shaft 322 and a second bushing structure 323. The second connecting ear 321 is connected to the outer wall of the second stove 21. The first bushing structure 313 is cylindrical, and its inner diameter matches the outer diameter of the second connecting longitudinal shaft 322, so that the second connecting longitudinal shaft 322 can be embedded and form a clearance fit. The second bushing structure 323 is cylindrical, and its inner diameter matches the outer diameter of the first connecting longitudinal shaft 312, so that the first connecting longitudinal shaft 312 can be inserted to form a clearance fit. The first connecting longitudinal axis 312 and the second connecting longitudinal axis 322 are arranged sequentially along the same axis, and after they are respectively embedded in the corresponding bushings, the first hinge seat 31 and the second hinge seat 32 can rotate relative to each other around the axis.

[0010] Preferably, the heating structure 12 includes: a heating burner head 121 installed on the top of the first stove 11, and a heating mesh frame 122 mounted outside the heating burner head 121. The top of the heating mesh frame 122 is provided with a plurality of first support rods 1221, the top surfaces of the plurality of first support rods 1221 are on the same horizontal plane, and the plurality of first support rods 1221 are used to contact the support surface when the heating assembly 1 is placed upside down to form a stable support.

[0011] Preferably, the second stove 21 includes: a stove base 211, a combustion burner head 212 disposed on the stove base 211, and a stove frame 213 mounted outside the combustion burner head 212. The stove frame 213 has a plurality of second support rods 2131 evenly distributed around its circumference, and the top surface formed by the plurality of second support rods 2131 is on the same horizontal plane.

[0012] Preferably, the surface of the second support rod portion 2131 is further provided with a wave-shaped convex ridge structure 21310.

[0014] Preferably, the first stove 11 is provided with a first handle 51 on the outer wall of the non-hinged side, and the second stove 21 is provided with a second handle 52 on the outer wall of the non-hinged side.

[0015] Preferably, both the first stove 11 and the second stove 21 have multiple raised pillars 6 and multiple heat dissipation strip holes 7 protruding from their bottoms.

[0016] Compared with the prior art, the beneficial effects of this utility model are: 1. This design employs a detachable hinged structure, allowing the heating and cooking components to be integrated or separated, and to rotate relative to each other, creating different relative positions for different functions. It offers four usage modes: simultaneous heating and cooking, heating only, cooking only, and heating and cooking separately. This addresses the pain points of traditional integrated stoves, such as fixed functions, inability to accommodate seasonal and scenario needs, and poor portability. Users can freely choose the optimal usage mode based on their actual needs, such as cooking only in summer, primary heating and temporary cooking in winter, or multiple people requiring different functions simultaneously. This meets the diverse needs of today's customers, making it more convenient and significantly improving the user experience. Furthermore, in its folded and separated state, the device's size is significantly reduced, making it easy to store and carry, ideal for outdoor activities with limited space, such as ice fishing and camping.

[0017] 2. In this case, the first and second connecting longitudinal axes of the hinge structure are arranged sequentially along the same centerline, forming a double-support structure. Compared with a single-axis structure, the stress distribution is more uniform, effectively avoiding deformation or loosening caused by stress concentration on one side, and ensuring a stable connection between the heating and cooking components during frequent opening and closing. The inner diameter of the first bushing structure and the outer diameter of the second connecting longitudinal axis, as well as the inner diameter of the second bushing structure and the outer diameter of the first connecting longitudinal axis, are all designed to match, forming a clearance fit. This ensures that the first and second hinge seats can rotate smoothly relative to each other around the centerline while reducing axial movement and radial offset, making operation more convenient.

[0023] Figure 6 This is the second structural diagram of the heating and cooking stove in the unfolded state in this case. Detailed Implementation

[0024] The following examples provide a more detailed description of the features and other related characteristics of this utility model, to facilitate understanding by those skilled in the art: like Figures 1 to 6 A heating and cooking stove, comprising: Heating component 1 is used to realize the heating function; the heating component 1 includes a first stove 11 and a heating structure 12 installed on the top of the first stove 11; Cooking component 2, used to realize cooking function, includes a second stove 21. The first stove 11 and the second stove 21 are independent combustion systems and can operate independently.

[0025] The hinge structure 3 is used to connect the heating component 1 and the cooking component 2, and to enable the two to rotate relative to each other around the hinge axis. The hinge structure 3 is a detachable structure, which allows the two to rotate relative to each other and can also be completely separated, thereby achieving multiple functional states by changing the relative positions of the two. In specific implementation, the rotation angle range of the hinge structure 3 is 0°-180°, with 0° corresponding to the unfolded state (horizontal arrangement) and 180° corresponding to the folded state (stacked vertically). By disassembling the hinge structure, the two can be completely separated (separated state), meeting the switching needs of different usage scenarios.

[0026] The relative position of the heating and cooking stove includes: In the unfolded state: the heating component 1 and the cooking component 2 rotate relative to each other around the hinge axis 33 of the hinge structure 3, so that the two are arranged laterally in the same horizontal plane, the bottom of the first stove 11 and the bottom of the second stove 21 are on the same support plane, and the outer walls of the first hinge seat 31 and the second hinge seat 32 are opposite to each other; at this time, they are used to achieve heating and cooking functions together. Folded state: After the cooking component 2 is rotated 180 degrees around the hinge structure from the unfolded state, it is in an inverted state with the bottom facing up, located directly below the heating component 1, so that the second stove 21 is in an inverted position, and the bottom of the first stove 11 is in contact with the bottom of the second stove 21. At this time, the heating component 1 is placed upright above the cooking component 2 to realize the heating function alone; the above folded state is the upright folded state.

[0027] In addition, after being folded, the whole thing can be flipped over to form a reverse folded state, which can also make the cooking component 2 be placed on top of the heating component 1 in the forward position. The heating component 1 is then placed upside down to perform the cooking function independently. Separation state: The first hinge seat 31 and the second hinge seat 32 of the hinge structure 3 are separated from each other, so that the connection between the heating component 1 and the cooking component 2 is released. The two are independent components, used to realize heating or cooking functions separately. In this way, heating or cooking functions can be realized separately from a distance without interfering with each other.

[0028] As described above, this application employs a detachable hinged structure, allowing the heating and cooking components to be integrated or separated, and to rotate relative to each other, forming different relative positions to achieve different functional uses. This enables four usage modes: simultaneous heating and cooking, heating only, cooking only, and heating and cooking separately. This solves the pain points of traditional integrated stoves, such as fixed functions, inability to accommodate seasonal and scenario needs, and poor portability. Users can freely choose the optimal usage mode according to their actual needs (e.g., cooking only in summer, primary heating and temporary cooking in winter, or multiple people needing different functions simultaneously), meeting the diverse needs of today's customers, making it more convenient to use and greatly improving the user experience. Furthermore, in the folded and separated state, the device's size is significantly reduced, making it easy to store and carry, ideal for outdoor activities with limited space, such as ice fishing and camping.

[0029] like Figure 5 As shown, in a preferred embodiment, the hinge structure 3 includes a first hinge seat 31 and a second hinge seat 32. The first hinge seat 31 is connected to the outer side wall of the heating component 1, and includes a first connecting ear 311, a first connecting longitudinal shaft 312 and a first bushing structure 313. The first connecting ear 311 is connected to the outer side wall of the first stove 11. The second hinge seat 32 is connected to the outer wall of the cooking component 2, and includes a second connecting ear 321, a second connecting longitudinal shaft 322 and a second bushing structure 323. The second connecting ear 321 is connected to the outer wall of the second stove 21. The first bushing structure 313 is cylindrical, and its inner diameter matches the outer diameter of the second connecting longitudinal shaft 322, so that the second connecting longitudinal shaft 322 can be embedded and form a clearance fit. The second bushing structure 323 is cylindrical, and its inner diameter matches the outer diameter of the first connecting longitudinal shaft 312, so that the first connecting longitudinal shaft 312 can be inserted to form a clearance fit. The first connecting longitudinal shaft 312 and the second connecting longitudinal shaft 322 are arranged sequentially along the same axis, and after they are respectively embedded in their corresponding bushings, the first hinge seat 31 and the second hinge seat 32 can rotate relative to each other around the axis. In specific implementation, a reverse pulling force can be applied to the first hinge seat and the second hinge seat along the axis, causing the first connecting longitudinal shaft 312 to disengage from the second bushing structure 323, and the second connecting longitudinal shaft 322 to disengage from the first bushing structure 313, thereby realizing the disassembly and separation of the heating component and the cooking component.

[0030] As described above, the first connecting longitudinal axis 312 and the second connecting longitudinal axis 322 of the hinge structure in this case are arranged sequentially along the same axis, forming a double-support point. Compared with a single-axis structure, the force distribution is more uniform, which can effectively avoid deformation or loosening caused by stress concentration on one side, and ensure that the heating component 1 and the cooking component 2 maintain a stable connection during frequent opening and closing. The inner diameter of the first bushing structure 313 and the outer diameter of the second connecting longitudinal axis 322, and the inner diameter of the second bushing structure 323 and the outer diameter of the first connecting longitudinal axis 312 are all designed to match, forming a clearance fit. This ensures that the first hinge seat 31 and the second hinge seat 32 can rotate smoothly relative to each other around the axis, while reducing axial movement and radial offset, making operation more convenient.

[0031] like Figures 1-4 As shown, in a preferred embodiment, the heating structure 12 includes a heating burner 121 and a heating mesh frame 122. The heating burner 121 is fixedly installed on the top of the first stove 11 to provide heating heat. The heating mesh frame 122 is a ring-shaped frame structure, coaxially sleeved on the outside of the heating burner 121, and the bottom of the heating mesh frame 122 is fixedly connected to the top of the first stove 11. The top of the heating mesh frame 122 is provided with multiple first support rods 1221, and the top surfaces of the multiple first support rods 1221 are on the same horizontal plane. In specific implementation, there are 3-4 first support rods 1221, which are evenly distributed along the circumference of the stove frame 122. When the heating component 1 is placed upside down in the reverse folded state, the top surface of the first support rod 1221 contacts the supporting surface (such as the ground or tabletop), forming a stable support for the whole (heating component and the cooking component above), which facilitates the use of the cooking function.

[0032] Thus, the heating mesh frame 122 in this case is located on the outside of the heating burner head 121, forming a protective structure that can effectively prevent the user from direct contact with the high-temperature burner head, reducing the risk of burns. At the same time, the design of multiple first support rods 1221 on the top of the heating mesh frame 122 and their coplanar top surfaces forms multi-point stable support through the support rods. This ensures that the heating component 1 is placed on the support surface when upside down, avoiding the risk of tipping over due to single-point contact, ensuring stable operation of the cooking component 2 in the reverse folded state, making it convenient to use and suitable for individual cooking scenarios.

[0033] like Figures 1-4 As shown, in a preferred embodiment, the second stove 21 includes: a stove base 211, a combustion burner 212 disposed on the stove base 211, and a stove frame 213 mounted outside the combustion burner 212. The stove frame 213 has a plurality of second support rods 2131 evenly spaced circumferentially, and the top surface formed by the plurality of second support rods 2131 is on the same horizontal plane. The surface of the second support rods 2131 is also provided with a wavy ridge structure 21310 to increase friction and make the cookware more stable.

[0034] Thus, by setting multiple second support rods 2131 and wave-shaped convex rib structure 21310, on the one hand, it ensures that the cookware is placed stably when the second stove 21 is placed upright; on the other hand, when it is folded upside down, it can form a support plane to support the heating components above, which is suitable for independent heating scenarios and solves the heating / cooking safety hazards caused by outdoor bumps.

[0035] like Figure 6 As shown, in a preferred embodiment, the first stove 11 has a latch 41 with a slot on its bottom side away from the hinge, and the second stove 21 has a protruding latch 42 on its bottom side away from the hinge for engaging and locking with the latch 41 when rotated under the first stove 11. Specifically, when the cooking component 2 rotates under the first stove 11 (in the folded state), the protruding latch 42 aligns with the slot of the latch 41, applies downward pressure, and the latch's barb engages in the slot, thus locking the appliance. This ensures stability when both appliances are folded. On the one hand, when the heating or cooking functions are used individually while both appliances are stacked, they will not easily shake or accidentally separate, making them more reliable and practical. On the other hand, they are also easy to carry when folded.

[0036] like Figure 1 As shown, in a preferred embodiment, the first stove 11 has a first handle 51 on the outer wall of its non-hinged side, and the second stove 21 has a second handle 52 on the outer wall of its non-hinged side. This facilitates transportation and position adjustment without requiring additional handling tools.

[0037] like Figure 6 As shown, in a preferred embodiment, both the first stove 11 and the second stove 21 have multiple raised pillars 6 and multiple heat dissipation strip holes 7 protruding from their bottoms. Specifically, the multiple raised pillars 6 are preferably four pillars located at the four corners of the bottom of the corresponding stove, facilitating four-corner support and ensuring the stove can be placed stably on uneven outdoor ground (such as snow or grass), avoiding uneven heat distribution caused by flame tilting or potential safety hazards. The heat dissipation strip holes prevent deformation of the stove base due to high temperatures, extending its service life.

[0038] In summary, this case discloses a heating and cooking stove, relating to the field of stove technology, aiming to solve the problems of fixed functions, poor scene adaptability, and insufficient portability of traditional integrated outdoor stoves. The stove includes a heating component, a cooking component, and a detachable hinge structure. The heating component comprises a first stove and a top heating structure, while the cooking component comprises a second stove. The hinge structure consists of first and second hinge seats, which achieve relative rotation and detachment through a clearance fit between the longitudinal axis and the bushing, allowing for three states: unfolded, folded, and separated. In the unfolded state, the two components are arranged horizontally, simultaneously providing heating and cooking. In the folded state, the cooking component is placed upside down below the heating component, providing heating independently. In the separated state, the two components are used independently. Furthermore, the stove features a lock to secure the folded state, a handle for easy carrying, a raised support column for stability, and ventilation holes to extend its lifespan. This stove is flexible in function, highly portable, and suitable for outdoor scenarios such as ice fishing and camping.

[0039] As stated above, this case protects a heating and cooking stove, and all technical solutions that are the same as or similar to this case should be considered to fall within the scope of protection of this case.
