Abstract
Description
Technical Field
[0001] This utility model relates to the field of stove structure technology, and in particular to a novel wood-fired stove bottom. Background Technology
[0002] During the cold season, fire pits are a common tool for heating, and they can also be used for roasting food. Currently, most fire pits on the market have a straight or simple folded edge.
[0003] This traditional edge design has certain drawbacks: when a rack needs to be placed on the brazier to support items such as grills and pots, the contact area between the rack and the edge of the brazier is small, and there is a lack of effective limiting structure, which makes the rack prone to sliding or even tipping over, resulting in poor safety and stability. In addition, the straight or simply folded edges are relatively sharp, which can easily cut the user's hands during handling or use, posing a safety hazard.
[0004] Existing wood-burning braziers mostly have a closed bottom structure. During use, poor air circulation affects fuel combustion efficiency, leading to rapid fuel consumption and incomplete combustion, which produces excessive smoke, impacting the environment and human health. Furthermore, the closed bottom reduces friction with the ground, making it prone to movement due to accidental collisions and lacking stability. Therefore, a novel wood-burning stove bottom is proposed to address these issues. Utility Model Content
[0005] To overcome the above shortcomings, this utility model provides a new type of wood-fired stove bottom, which aims to improve the existing technology by addressing the problems of the edge of the existing fire pit easily scratching users, the shelf easily sliding and tipping over, and the low combustion efficiency and excessive smoke.
[0006] To achieve the above objectives, the present invention adopts the following technical solution: a novel wood-fired stove bottom, comprising a basin body, wherein a rolled edge structure is provided at the top edge of the basin body, the rolled edge structure is formed by rolling the edge of the basin body inward, and a support groove is provided on the inner side of the rolled edge structure.
[0007] As a further description of the above technical solution: the bottom of the basin has a hollow structure.
[0008] As a further description of the above technical solution: the support groove is annular.
[0009] As a further description of the above technical solution: the cross-section of the rolled edge structure is arc-shaped after rolling.
[0010] This utility model has the following beneficial effects:
[0011] 1. In this utility model, by setting a rolled edge structure at the top edge of the basin and opening an annular support groove on the inner side of the rolled edge structure, the support legs of the frame can be effectively limited, preventing the frame from sliding or tipping over during use, thereby significantly improving the stability and safety of the frame. Furthermore, the rolled edge structure eliminates the sharp edges of the basin, avoiding the risk of users being scratched when handling or using the basin, further enhancing safety.
[0012] 2. In this utility model, the hollow structure can be various shapes such as long strips, circles, and rhombuses. This design facilitates air circulation, providing sufficient oxygen for fuel combustion, thereby improving fuel combustion efficiency and reducing fuel consumption. Simultaneously, it ensures more complete fuel combustion, reduces smoke production, improves the usage environment, and is beneficial to human health. Furthermore, the hollow structure reduces the overall weight of the pot, making the wood-burning stove easier to move. Attached Figure Description

[0020] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.
[0021] Reference Figure 1 , Figure 4 , Figure 5 This utility model provides an embodiment of a novel wood-fired stove base, comprising a basin 1. A rolled edge structure 2 is provided at the top edge of the basin 1. The width of the rolled edge structure 2 is 1-8 cm. The rolled edge structure 2 increases the contact area between the frame and the edge of the basin 1, and the support groove 3 effectively limits the support feet of the frame, preventing the frame from sliding or tipping over during use, thus improving the stability and safety of the frame. The rolled edge structure 2 eliminates the sharp edges of the basin 1, avoiding the risk of users being scratched when handling or using the basin 1, and improving safety. The rolled edge structure 2 is formed by rolling the edge of the basin 1 inwards. A support groove 3 is provided on the inner side of the rolled edge structure 2. The support groove 3 is annular. When the basin 1 needs to be placed on the frame, the support feet of the frame can be embedded in the support groove 3 of the rolled edge structure 2 of the basin 1, achieving limitation and fixation of the frame. The cross-section of the rolled edge structure 2 after rolling is arc-shaped.
[0022] Reference Figure 1 - Figure 3 The bottom of the basin 1 has a hollow structure 4, which can be long, round, or rhomboid. The total area of the hollow structure 4 accounts for 30% to 60% of the total area of the bottom of the basin 1. The hollow structure 4 at the bottom of the basin 1 facilitates air circulation, provides sufficient oxygen for fuel combustion, improves fuel combustion efficiency, reduces fuel consumption, and makes fuel combustion more complete, reducing the amount of smoke generated, improving the usage environment and benefiting human health. The hollow structure 4 reduces the overall weight of the basin 1, making the fire basin easier to move.
[0023] Working principle: First, carefully inspect the overall structure of the basin 1 to ensure that there are no defects such as cracks or damage, especially the rolled edge structure 2 and the support groove 3. Check whether the rolled edge structure 2 is firm and not loose or deformed, and whether the shape of the support groove 3 is complete and whether the inner wall is smooth to ensure that it can function properly. Check the hollow structure 4 at the bottom of the basin 1 to confirm that the edges of each hollow part are neat and without sharp burrs to avoid accidental injury to the user during use. At the same time, ensure that the shape and size of the hollow structure 4 meet the design requirements to ensure the effect of air circulation.
[0024] Prepare suitable fuels, such as wood and straw, according to the needs of the wood-burning stove. Cut or arrange the fuel into a size and shape suitable for putting into the stove. Generally, the length of the fuel should be less than the diameter of the basin 1 so that it can be put in smoothly and burn fully. Select a rack that matches the bottom of the stove and check whether the support legs of the rack are intact and whether the length and shape match the support groove 3 of the rolled edge structure 2. Ensure that the rack can be placed stably on the basin 1 and that the support legs can be smoothly inserted into the support groove 3.
[0025] Installation Stage: Select a flat and stable ground as the placement location for the wood-burning stove. Place the pot body 1 stably on the ground, ensuring that its bottom is in close contact with the ground to prevent the pot body 1 from shaking due to uneven ground, which would affect subsequent use. Carefully place the prepared rack on the rolled edge structure 2 of the pot body 1, aligning the support feet of the rack with the support groove 3 on the inner side of the rolled edge structure 2. Then gently press down on the rack to make the support feet fully embedded in the support groove 3. Check whether the rack is placed stably. Gently shake the rack by hand to confirm that it will not slide or tip over under the limiting effect of the support groove 3, ensuring that the connection between the rack and the pot body 1 is stable and reliable.
[0026] Adding fuel: Open the stove door of the wood-burning stove and put the prepared fuel into the basin 1 through the stove door. Pay attention to the arrangement of the fuel. Make sure there are gaps between the fuels so that air can enter the fuel smoothly and promote combustion. Add fuel in an appropriate amount according to the required firepower. Avoid adding too much fuel at once, which may lead to incomplete combustion or excessive firepower and affect the performance.
[0027] Ignite the fuel: Use a match, lighter or other ignition tool to ignite the fuel. You can start igniting from the edge or bottom of the fuel and let the flame gradually spread to the entire fuel pile. Be careful during the ignition process to avoid burning your hands or causing other accidents. In the early stages of fuel combustion, a lot of smoke may be produced. At this time, you should keep the ventilation good to prevent the smoke from accumulating indoors and affecting air quality.
[0028] Adjusting fuel and ventilation: Adjust the amount and placement of fuel according to the combustion situation. If the fire is too weak, add fuel or adjust the placement of fuel to make the flame stronger. If the fire is too strong, reduce the amount of fuel or gently stir the fuel with a tool to weaken the flame. Utilize the hollow structure 4 at the bottom of the pot 1 to control the amount of air entering by adjusting the ventilation opening of the wood-burning stove or leaving appropriate ventilation space around the stove, thereby regulating the combustion speed and fire intensity of the fuel, ensuring that the fuel can burn completely, and avoiding the fuel from going out or producing too much smoke due to poor ventilation.
[0029] Extinguishing the fuel: After use, the fuel needs to be extinguished in time. You can use the fire extinguishing device that comes with the wood stove, such as closing the vents and covering the stove lid to cut off the air supply and let the flame gradually extinguish. If there is no fire extinguishing device, you can use water, sand or other fire extinguishing materials to extinguish the flame, but pay attention to the safety of the fire extinguishing method to avoid causing other accidents. For example, do not pour water directly on burning wood to avoid producing a large amount of steam and sparks.
[0030] Clean the bottom of the furnace: After the fuel has been completely extinguished and the temperature has dropped, carefully clean the ash and unburned fuel residue in the basin 1 to avoid burning your hands. Properly dispose of the cleaned ash and residue to avoid polluting the environment.
[0031] Storage of the stove bottom and shelves: Place the cleaned pot 1 and shelves in a dry, well-ventilated place to prevent them from getting damp and rusting. Also, make sure to keep the stove bottom and shelves out of reach of children and pets to ensure safe storage.
[0032] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
