Description

Technical Field

[0001] This invention belongs to the field of camping stove technology, specifically relating to an easy-to-carry camping stove. Background Technology

[0002] Outdoor camping stoves are commonly carried by people when participating in outdoor camping activities for ignition and heating.

[0003] When camping outdoors, there are many types of equipment needed, but people have limited carrying capacity. Therefore, camping stoves need to be smaller in size to save space. However, existing camping stoves generally include a stove frame, a support bracket for cooking utensils, and legs. The support bracket and legs are generally fixed directly to the stove frame with screws.

[0004] Because the legs are directly fixed to the stove frame, the camping stove is quite bulky and difficult to carry. Also, because the support is fixed to the stove frame, it cannot accommodate cooking utensils of different sizes. Summary of the Invention

[0005] This invention provides an easy-to-carry camping stove, aiming to solve the problems of existing camping stoves being difficult to carry and unable to adapt to cooking utensils of different sizes.

[0006] To solve the above-mentioned technical problems, the technical solution adopted by the present invention is as follows:

[0007] A portable camping stove includes a stove frame, on which a flame generator is mounted, and on which a control component for controlling the flame generator is also mounted.

[0008] The furnace frame is also provided with support legs, which are mounted on the furnace frame via a folding mechanism;

[0009] The stove rack is also equipped with a support for cooking utensils. The support is mounted on the legs. When the legs are folded by the folding mechanism, the support folds together with the legs.

[0010] The side of the support that contacts the cooking tool has a groove to reduce the contact area between the support and the cooking tool, and the groove is evenly distributed along the length of the support.

[0011] A further improved solution: The support has three legs, which are evenly arranged around the circumference of the flame generator, and the bracket corresponds one-to-one with the support legs.

[0012] Based on the above technical solution, the three legs are evenly arranged around the circumference of the flame generator, which is based on the mechanical principle of stability. In three-dimensional space, for an object to achieve a stable state, its support points need to form a stable supporting surface. When the three legs are evenly distributed around the flame generator, their points of contact with the ground form an approximately equilateral triangle supporting surface. An equilateral triangle has extremely high stability in geometry because its three sides are of equal length and its three interior angles are also equal. It can evenly distribute the gravity from the cooking utensils and flame generator above, as well as any external forces that may be applied, allowing the camping stove to remain balanced and less prone to tipping over in various terrains and usage conditions.

[0013] A further improved solution: The support includes a sliding foot slidably connected to the furnace frame and a rotating foot rotatably connected to the furnace frame. There are two rotating feet, and the included angle between the two rotating feet is 120 degrees. The two rotating feet are located on both sides of the sliding foot, and the included angle between the sliding foot and the rotating foot is 120 degrees.

[0014] Based on the aforementioned technical solution—the combined design of sliding and rotating feet, and their specific angle settings—the camping stove can better adapt to various complex terrains. Whether on flat grass, rugged mountains, or soft sand, the stove can adjust its position through the sliding of the sliding feet and the rotation of the rotating feet, maintaining stable support and providing reliable protection for outdoor cooking. For example, when camping in mountainous areas, where the ground may have significant slopes and undulations, this design allows the stove to easily cope, ensuring the safety and smooth progress of the cooking process. The approximately equilateral triangle support structure formed by the three supporting feet, along with the reasonable angle settings, greatly improves the stability of the camping stove. During cooking, even when subjected to external forces such as wind or foot traffic, the stove remains balanced and is not easily tipped over. This not only avoids safety accidents caused by the stove tipping over but also ensures the safety of cooking utensils and food, reducing losses.

[0015] A further improved solution: The folding mechanism includes a groove on the sliding foot, and a slide rail on the furnace frame that cooperates with the groove. The slide rail and the furnace frame are an integral structure.

[0016] Based on the above technical solution, the combined design of the sliding groove and rail makes the folding operation of the camping stove extremely convenient and smooth. Users only need to apply appropriate external force, and the sliding foot can easily slide along the rail, achieving quick folding and unfolding. This convenient operation saves users time and effort, especially in outdoor environments, enabling rapid storage and setup of the camping stove and improving the efficiency of outdoor activities. For example, when an emergency campsite relocation is needed, users can quickly fold the camping stove for easy carrying and transportation.

[0017] A further improved solution: The bracket set on the sliding foot includes a support plate, there are two support plates, and the groove is provided on both support plates. The support plate is fixed to the sliding foot by screws.

[0018] Based on the above technical solution: the design of two support plates expands the support area, which can more evenly distribute the weight of cooking utensils, making the camping stove more stable when supporting cooking utensils. Even when subjected to external impact during cooking or when the cooking utensils themselves are heavy, it can maintain good balance and reduce the risk of tipping over. For example, when cooking with a large cast iron pot, the two support plates can jointly bear the weight of the pot, preventing the support plates from deforming or the camping stove from tipping over due to excessive localized force.

[0019] A further improved solution: The folding mechanism further includes a rotating shaft disposed on the furnace frame, and the rotating foot is rotatably connected to the furnace frame through the rotating shaft. The rotating foot and the rotating shaft correspond one-to-one, and the bracket disposed on the rotating foot is an integral structure with the rotating foot.

[0020] Based on the above technical solution, the integrated structure of the support and rotating feet significantly enhances the overall structural strength of the camping stove. When subjected to significant weight or external impact, the integrated structure better resists deformation and damage, ensuring the stability of the camping stove. For example, when using heavy cooking utensils, the integrated support and rotating feet provide stable support without loosening or wobbling, offering reliable safety during the cooking process.

[0021] A further improved solution: The folding mechanism includes a rotary table rotatably connected to the furnace frame, the rotary table having an end face thread, the support legs slidably connected to the furnace frame, and the support legs also having threaded grooves that mate with the end face thread. Rotating the rotary table causes the three support legs to simultaneously and at the same speed approach or move away from the flame generator. The furnace frame is also provided with a guide rail, and the support legs have guide grooves that mate with the guide rail.

[0022] Based on the above technical solution, the distance between the three support legs and the flame generator can be adjusted simultaneously and at the same speed by rotating the turntable. This design allows users to quickly and accurately adjust the support status of the camping stove according to different cooking needs and terrain conditions. For example, when cooking with larger pots, the support legs can be moved away from the flame generator to expand the cooking space; this synchronous adjustment method avoids the tedious operation of adjusting each support leg individually, saving time and effort.

[0023] A further improved solution: The furnace frame is also equipped with a worm gear that drives the rotary table, and the rotary table is equipped with a worm wheel that cooperates with the worm gear. The worm wheel and the rotary table are an integral structure, and the worm wheel and the rotary table are coaxially arranged.

[0024] Based on the above technical solution, the self-locking property of the worm gear drive provides a safety guarantee for the use of the camping stove. When the camping stove supports cooking utensils, the legs are subjected to external forces such as the weight of the utensils and vibrations generated during cooking. Because the worm gear cannot drive the worm to rotate in the reverse direction, the legs will not move on their own due to these external forces, ensuring the stability of the camping stove. Even under significant external forces, the camping stove can be placed stably on the ground without the risk of tipping over, ensuring the user's cooking safety.

[0025] A further improved solution: An operating shaft is provided on the worm gear, the operating shaft is coaxially arranged with the worm gear, and the operating shaft and the worm gear are an integral structure. The furnace frame is also provided with a mounting plate for mounting the operating shaft, the mounting plate and the furnace frame are an integral structure. One end of the worm gear is provided with a handle for easy rotation of the worm gear.

[0026] Based on the above technical solution, the coaxial integrated structure of the operating shaft and worm gear, along with the handle, allows users to easily rotate the worm gear. Users only need to grip the handle and apply a small amount of force to rotate the worm gear via the operating shaft, thereby rotating the turntable and adjusting the support legs. For example, after carrying a camping stove to a campsite, even after a long hike and some physical exertion, users can easily use the handle to adjust the stove's support position, preparing for cooking.

[0027] A further improved solution: The furnace frame is provided with a mounting ring for mounting the rotary table. The rotary table is rotatably connected to the mounting ring. A deep groove ball bearing is provided between the rotary table and the mounting ring. The outer ring of the deep groove ball bearing is interference-fitted with the rotary table, and the inner ring of the deep groove ball bearing is interference-fitted with the mounting ring.

[0028] Based on the above technical solution, the rolling friction characteristics of the deep groove ball bearing result in minimal resistance during rotation of the rotary table, enabling smooth rotation. Users will not experience noticeable jamming or resistance when rotating the worm gear via the handle, making operation easier and more convenient. For example, when adjusting the position of the camping stove's support legs, the rotary table rotates quickly and smoothly, allowing the legs to reach the desired position rapidly and accurately, improving adjustment efficiency.

[0029] The beneficial effects of this invention are as follows:

[0030] This invention utilizes a folding mechanism to fold the legs, significantly reducing the size of the camping stove and making it convenient for outdoor camping. This saves valuable carrying space, allowing users to carry more essential equipment. The linked design of the legs and support allows for adjustment to accommodate different sizes of cooking utensils, making the camping stove compatible with various cooking tools and meeting diverse outdoor cooking needs.

[0031] The groove design reduces the contact area between the stand and cooking utensils, increases friction, and effectively prevents cooking utensils from slipping. At the same time, the adjustable position of the feet ensures overall stability when using different cooking utensils, improving the safety and reliability of outdoor cooking.

[0032] In traditional camping stoves, the legs are directly fixed to the frame, making it impossible to reposition the legs when storing the stove and resulting in a large overall footprint. This portable camping stove, however, uses a folding mechanism to mount the legs on the frame. When the stove needs to be stored, the folding mechanism allows the legs to rotate and fold towards the frame. This significantly reduces the space occupied by the previously extended legs, making the overall size of the stove smaller and saving space, thus meeting the portability requirements of outdoor camping equipment.

[0033] The support bracket is mounted on the legs, and the legs fold or unfold together with the bracket. When using different sized cooking utensils, such as switching from a smaller kettle to a larger wok, the center of gravity and required support area change due to the change in utensil size. In this case, the legs are unfolded by operating the folding mechanism, moving them to the appropriate position. Because the bracket moves with the legs, it is positioned to support the cooking utensil of that size, ensuring greater stability of the camping stove when supporting different sized utensils. For example, a larger wok requires a wider support surface and a more stable center of gravity; unfolding the legs to the appropriate position allows the bracket to better support the wok and prevent it from tipping over.

[0041] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. It should be understood that the specific embodiments described herein are merely for explaining the present invention and are not intended to limit the present invention. All other embodiments obtained by users of the art based on the embodiments of the present invention without creative effort are within the protection scope of the present invention.

[0042] refer to Figures 1 to 4 A portable camping stove includes a stove frame 1, a flame generator 2 is mounted on the stove frame 1, and a control component for controlling the flame generator 2 is also mounted on the stove frame 1.

[0043] The furnace frame 1 is also provided with support legs 3, which are mounted on the furnace frame 1 by means of a folding mechanism;

[0044] The stove rack 1 is also provided with a support 4 for supporting cooking utensils. The support 4 is installed on the support leg 3. When the support leg 3 is folded by the folding mechanism, the support 4 is folded together with the support leg 3.

[0045] The side of the support 4 that contacts the cooking tool is provided with a groove 5 to reduce the contact area between the support 4 and the cooking tool. The groove 5 is evenly distributed along the length of the support 4.

[0046] Specifically: There are three legs 3, which are evenly arranged around the circumference of the flame generator 2, and the bracket 4 corresponds to each leg 3.

[0047] In one embodiment of the folding mechanism: the support leg 3 includes a sliding leg 6 slidably connected to the furnace frame 1 and a rotating leg 7 rotatably connected to the furnace frame 1. There are two rotating legs 7, with an included angle of 120 degrees between them. The two rotating legs 7 are located on opposite sides of the sliding leg 6, and the included angle between the sliding leg 6 and the rotating leg 7 is 120 degrees. The folding mechanism includes a groove on the sliding leg 6, and a slide rail on the furnace frame 1 that mates with the groove. The slide rail and the furnace frame 1 are integrally formed. The bracket 4 on the sliding leg 6 includes a support plate 8, of which there are two pieces. Each support plate 8 has a groove 5, and the support plate 8 is fixed to the sliding leg 6 with screws. The folding mechanism also includes a rotating shaft on the furnace frame 1. The rotating legs 7 are rotatably connected to the furnace frame 1 via the rotating shaft, with each rotating leg 7 corresponding to one of the rotating shafts. The bracket 4 on the rotating leg 7 is integrally formed with the rotating leg 7. The bracket 4 mounted on the sliding foot 6 employs a design with two support plates 8, each with grooves 5, based on considerations of stability and compatibility with cooking tools. The two support plates 8 form a relatively wide support area, which better distributes the pressure applied by the cooking tool compared to a single support plate 8. The combined effect of the two support plates 8 reduces localized stress concentration and lowers the risk of damage to the support plates 8 due to excessive force.

[0048] A second embodiment of the folding mechanism: The folding mechanism includes a rotary disk 9 rotatably connected to the furnace frame 1. The rotary disk 9 is provided with an end face thread 10. The support legs 3 are slidably connected to the furnace frame 1. The support legs 3 are also provided with threaded grooves that mate with the end face thread 10. Rotating the rotary disk 9 causes the three support legs 3 to simultaneously and at the same speed approach or move away from the flame generator 2. The furnace frame 1 is also provided with a guide rail, and the support legs 3 are provided with guide grooves that mate with the guide rail. The furnace frame 1 is also provided with a worm gear 11 that drives the rotary disk 9. The rotary disk 9 is provided with a worm wheel 12 that mates with the worm gear 11. The worm wheel 12 and the rotary disk 9 are an integral structure and are coaxially arranged. An operating shaft 13 is provided on the worm gear 11, and the operating shaft 13 is coaxially arranged with the worm gear 11, forming an integral structure. A mounting plate for mounting the operating shaft 13 is also provided on the furnace frame 1, and the mounting plate is an integral structure with the furnace frame 1. A handle 14 for rotating the worm gear 11 is provided at one end. A mounting ring for mounting the rotary disk 9 is provided on the furnace frame 1, and the rotary disk 9 is rotatably connected to the mounting ring. A deep groove ball bearing is provided between the rotary disk 9 and the mounting ring. The outer ring of the deep groove ball bearing is interference-fitted with the rotary disk 9, and the inner ring of the deep groove ball bearing is interference-fitted with the mounting ring. In the folding mechanism, the rotary disk 9 is rotatably connected to the furnace frame 1 and has an end face thread 10. The support leg 3 is slidably connected to the furnace frame 1 and has a matching threaded groove, which utilizes the principle of helical transmission. When the rotary table 9 is rotated, the thread 10 on the end face of the rotary table 9 will generate relative movement with the threaded groove on the support leg 3. Since the support leg 3 is slidably connected to the furnace frame 1, its direction of movement is restricted, and it can only move along a specific direction. According to the characteristics of the screw drive, the rotational motion of the rotary table 9 will be converted into the linear motion of the support leg 3. Moreover, because the threaded grooves on the three support legs 3 are all engaged with the thread 10 on the end face of the rotary table 9, when the rotary table 9 is rotated, the three support legs 3 will simultaneously and at the same speed approach or move away from the flame generator 2. The guide rail provided on the furnace frame 1 and the guide groove provided on the support leg 3 are to further constrain the direction of movement of the support leg 3, ensuring its linearity and stability. The guide rail provides a fixed track for the support leg 3, and the guide groove is engaged with the guide rail, so that the support leg 3 can only slide along the direction of the guide rail and cannot deviate in other directions. In the camping furnace, the cooperation of the guide rail and the guide groove can prevent the support leg 3 from shaking or getting stuck during movement, ensuring that the three support legs 3 can accurately approach or move away from the flame generator 2.

[0049] The working principle of this embodiment:

[0050] Upon arrival at the campsite, remove the camping stove from its portable state and unfold the support leg 3 to the appropriate position using the folding mechanism. The support frame 4 will then unfold along with the support leg 3. Further fine-tune the position of the support leg 3 according to the specifications of the cooking utensils used, ensuring the support frame 4 can stably support the cooking utensils. Place the cooking utensils on the support frame 4 and use the control unit to turn on the flame generator 2 to begin cooking.

[0051] After cooking, first turn off the flame generator 2 and wait for it to cool down. Then, by operating the folding mechanism, fold the support leg 3 towards the stove frame 1. The support 4 will fold along with the support leg 3, restoring the camping stove to a smaller size for easy storage and carrying.

[0052] This invention is not limited to the above-mentioned optional embodiments. Under the premise of non-contradiction, the various solutions can be combined arbitrarily. Anyone can derive other forms of products under the guidance of this invention. However, no matter what changes are made in their shape or structure, all technical solutions that fall within the scope of the claims of this invention are within the protection scope of this invention.
