Abstract
Description
Technical Field
[0001] This utility model belongs to the field of mesh cover structures for preventing charcoal from falling and melting, specifically, it relates to a mesh cover structure for preventing charcoal from falling and melting. Background Technology
[0002] In scenarios involving charcoal burning, such as barbecuing and charcoal heating, charcoal pieces may fall or melt during combustion. On one hand, falling charcoal can easily cause a fire hazard, especially during outdoor barbecues, where fallen charcoal can ignite surrounding vegetation, leading to an uncontrollable fire. On the other hand, some charcoal may melt at high temperatures. If this molten charcoal comes into direct contact with the bottom of the grill or heating equipment, it can easily damage the equipment and reduce its lifespan. Traditional metal mesh covers, while providing some protection, suffer from problems such as the mesh being easily clogged by charcoal residue and the metal deforming at high temperatures. Furthermore, existing mesh cover structures lack effective designs to prevent the seepage of molten charcoal. To ensure safety and equipment stability during charcoal burning, developing a mesh cover structure that effectively prevents charcoal from falling and melting is crucial. This new mesh cover structure will address many of the shortcomings of traditional mesh covers, ensuring efficient and safe charcoal burning.
[0003] Existing activated carbon components consist of activated carbon cotton covering the outer surface of a PP material carbon frame, which is then heat-pressed using ultrasound. The inside of the carbon frame contains activated carbon granules. However, in actual use, when the stove's heat is high, the fibrous activated carbon cotton covering the outer surface is easily melted by the heat. After the activated carbon cotton breaks, carbon granules fall onto the stove, causing user complaints. Moreover, the fibrous activated carbon cotton is relatively thick, which greatly affects the air intake of the duct. After installing the activated carbon component, the range hood's airflow is reduced by half. Utility Model Content
[0004] The technical problem to be solved by this utility model is to overcome the shortcomings of the prior art and provide a mesh cover structure to prevent carbon from falling and melting, thus solving the problems mentioned in the background art.
[0005] To solve the above-mentioned technical problems, the basic concept of the technical solution adopted by this utility model is as follows:
[0006] A mesh cover structure for preventing charcoal from falling and melting includes an outer shell, an inner shell structure installed in the inner cavity of the outer shell, the size of the inner shell structure being smaller than the inner side of the outer shell, a cavity structure reserved between the outer side of the inner shell structure and the inner side of the outer shell, the inner cavity structure being filled with activated carbon particles, the activated carbon particles filling the entire inner cavity structure.
[0007] Optionally, the top of the outer shell is fitted with an annular sealing plate by bolt fasteners, and the top of the inner shell structure is also fitted with the bottom of the annular sealing plate by bolt fasteners.
[0008] Optionally, the inner shell structure has openings on its sides and top for air circulation, and the openings are closed with a square grid made of nylon material.
[0009] Optionally, the bottom of the outer casing is provided with a through hole, and a carbon frame is inserted into the inner cavity of the through hole.
[0010] Optionally, the outer wall of the charcoal frame and the inner wall of the bottom through hole of the outer shell are provided with threaded structures. The charcoal frame is threadedly installed in the bottom through hole of the outer shell, and the top of the charcoal frame abuts against the bottom of the inner shell structure.
[0011] Optionally, the charcoal frame is specifically a bowl-shaped structure, with the inner side of the charcoal frame fitting against the outer side of the inner shell structure, and the inner side of the charcoal frame being hot-pressed to a square grid.
[0012] By adopting the above technical solution, the present invention has the following beneficial effects compared with the prior art. Of course, any product implementing the present invention does not necessarily need to achieve all of the following advantages at the same time:
[0013] When this technical solution is in use, especially when the stove has a high heat output, the nylon square mesh in the inner shell structure is not easily melted by heat, so the charcoal particles will not fall off. At the same time, the nylon square mesh is relatively thin, so it has little impact on the air intake of the air duct. After installing the activated carbon component, the air volume of the range hood is increased.
[0014] The specific embodiments of this utility model will be described in further detail below with reference to the accompanying drawings. Attached Figure Description
[0015] The accompanying drawings described below are merely some embodiments. Those skilled in the art can obtain other drawings based on these drawings without any creative effort. In the drawings:

[0018] Figure 3 This is a schematic diagram of the internal cross-sectional structure of the utility mesh cover. Detailed Implementation
[0019] The present invention will now be described in further detail with reference to the accompanying drawings.
[0020] Please see Figure 1-3 As shown, this embodiment provides a mesh cover structure to prevent carbon from falling and melting, including an outer shell 4, an inner shell 3 structure installed in the inner cavity of the outer shell 4, the size of the inner shell 3 structure is smaller than the size of the inner side of the outer shell 4, a cavity structure is reserved between the outer side of the inner shell 3 structure and the inner side of the outer shell 4, and the inner cavity of the cavity structure is filled with activated carbon particles 2, the activated carbon particles 2 fill the entire inner cavity of the cavity structure.
[0021] In this embodiment, the design of using interlayered and fully filled activated carbon particles 2 can greatly increase the filtration and purification effect of the entire mesh cover. By uniformly filling the cavity structure between the outer shell 4 and the inner shell 3 with activated carbon particles 2, the density and distribution of activated carbon are ensured. Activated carbon has a strong adsorption capacity and can effectively capture harmful substances, fumes, odors, and other tiny particles in the air, preventing them from entering the air circulation system.
[0022] The filling method of activated carbon granules 2 not only enhances its purification effect, but also increases the path of airflow through the activated carbon granules 2 through the partition design, allowing more air to come into contact with the activated carbon granules 2, thereby improving filtration efficiency. Due to the very large surface area of activated carbon, its unique porous structure allows pollutants to be adsorbed and removed in a shorter time, further enhancing the overall purification capacity of the mesh cover.
[0023] The top of the outer shell 4 is fitted with an annular sealing plate 5 by bolt fasteners, and the top of the inner shell 3 is also fitted with the bottom of the annular sealing plate 5 by bolt fasteners.
[0024] In this embodiment, the connection and fixation between the outer shell 4 and the inner shell 3 is achieved by the annular sealing plate 5, mainly to facilitate subsequent cleaning and maintenance operations.
[0025] The inner shell 3 has openings 6 on its sides and top for air circulation, and the openings 6 are closed with a square grid made of nylon material.
[0026] In this embodiment, the relatively large opening 6 ensures sufficient airflow space and does not negatively impact the ventilation effect of the entire mesh structure. The core purpose of this design is to optimize airflow, allowing more air to pass through the mesh quickly, thereby improving filtration efficiency and ensuring the normal operation of the equipment. When airflow is smoother, harmful substances and fumes in the air can be more efficiently adsorbed by the activated carbon particles 2, thus enhancing the purification effect. The larger opening 6 not only does not affect airflow but also helps improve overall ventilation performance. The nylon-like small square mesh is then used for sealing, primarily to prevent debris from falling in.
[0027] However, while creating a relatively large opening 6, it's also necessary to consider preventing debris from falling into the equipment. Therefore, the design employs a nylon-like small square mesh for sealing. This small square mesh effectively covers the opening 6, preventing debris, dust, or small particles from the external environment from entering the mesh cover, thus avoiding contamination of the filtration system or affecting its normal operation. The nylon small square mesh has high heat resistance and durability, and is not easily melted or damaged even under high temperatures or prolonged use.
[0028] Furthermore, the nylon mesh design not only prevents debris from falling in but also does not significantly obstruct airflow. Its fine mesh structure ensures that air can still flow smoothly even when enclosed, avoiding problems such as blocked air ducts or reduced airflow caused by enclosed designs.
[0029] The bottom of the outer shell 4 is provided with a through hole 7, and a carbon frame 1 is inserted into the inner cavity of the through hole 7. The main function of the carbon frame 1 is to support and place the activated carbon particles 2.
[0030] The outer wall of the charcoal frame 1 and the inner wall of the bottom through hole 7 of the outer shell 4 are provided with threaded structures. The charcoal frame 1 is threadedly installed in the bottom through hole 7 of the outer shell 4, and the top of the charcoal frame 1 abuts against the bottom of the inner shell 3 structure.
[0031] In this embodiment, the assembly method between the carbon frame 1 and the outer shell 4 using a threaded structure is mainly to facilitate the operation and maintenance work in the later use. Whether it is cleaning and maintaining the mesh cover itself, or replacing the activated carbon particles 2, it is more convenient.
[0032] Specifically, the charcoal frame 1 has a bowl-shaped structure. The inner side of the charcoal frame 1 fits against the outer side of the inner shell 3 structure, and the inner side of the charcoal frame 1 is hot-pressed to the square grid. The nylon small square grid on the inner shell 3 structure is fixed to the charcoal frame 1 by hot pressing, which not only solves the problem of reduced airflow after the activated carbon group is installed, but also prevents the carbon cotton from melting on the outer surface and causing the carbon material to fall off.
[0033] In this embodiment, when the stove has a high heat output, the nylon square grid in the inner shell 3 structure is not easily melted by heat, and the charcoal particles will not fall off. At the same time, the nylon square grid is relatively thin, so it has little impact on the air intake of the air duct. After the activated carbon component is installed, the air volume of the range hood increases.
[0034] This utility model is not limited to the above-described embodiments. Anyone should know that structural changes made under the guidance of this utility model, and any technical solutions that are the same as or similar to this utility model, fall within the protection scope of this utility model. Technical aspects, shapes, and structures not described in detail in this utility model are all publicly known technologies.
