Description

Technical Field

[0001] This utility model relates to the field of smoking devices, and in particular to a carbon box and an Arabic hookah. Background Technology

[0002] An Arabic hookah is a smoking device that requires a charcoal box above the bowl to operate. The charcoal box holds the lit charcoal, and the heat generated by the burning charcoal heats the hookah paste inside the bowl, producing smoke for the user to inhale. To achieve specific heat conduction or airflow control, some existing charcoal boxes typically have a central protrusion extending upwards from the center of their inner bottom surface. However, this central protrusion occupies internal space within the charcoal box. When the user needs to insert a large or irregularly shaped charcoal, this protrusion can cause interference and obstruction, preventing the charcoal from being placed stably at the bottom of the charcoal box, or even completely inserted. Utility Model Content

[0003] This invention aims to solve at least one of the technical problems existing in the prior art. To this end, this invention proposes a carbon box that allows for easy placement of carbon blocks while also facilitating heat circulation.

[0004] This utility model also proposes an Arabian hookah with the aforementioned carbon box.

[0005] According to a first aspect of the present invention, a carbon box is applied to an Arabian hookah. The carbon box includes a rim and a bottom wall. The rim is arranged around and connected to the edge of the bottom wall. The rim and the bottom wall enclose a receiving cavity. A heat dissipation cavity is formed below the bottom wall. A portion of the bottom wall is recessed downward to form an air passage groove. The side wall of the air passage groove is provided with a through hole. The receiving cavity, the air passage groove, the through hole, and the heat dissipation cavity are sequentially connected.

[0006] The carbon box according to the embodiments of this utility model has at least the following beneficial effects: By creating a receiving cavity enclosed by the surrounding edge and the bottom wall, the traditional central convex pillar structure is eliminated, resulting in a complete and spacious interior. This allows users to easily insert charcoal blocks of different sizes or irregular shapes, improving usability. Furthermore, by forming a heat dissipation cavity below the bottom wall, when the charcoal box is placed on the bowl of the hookah, this cavity creates a heat buffer and distribution area between the bottom wall and the bowl. The heat generated by the burning charcoal is first conducted to this heat dissipation cavity, and then radiated and transferred more evenly downwards through the air medium within the cavity. This effectively avoids the problem of excessively high local temperatures caused by direct heat contact, ensuring that the hookah tobacco paste is heated evenly, thereby improving the stability of the smoke and the flavor of the hookah.

[0007] According to some embodiments of the present invention, a portion of the bottom wall protrudes downward to form a convex post, and the air passage groove is formed inside the convex post. The lower bottom surface of the bottom wall protrudes to form an annular portion, which surrounds the convex post. Along the direction of gravity, the lower end of the annular portion protrudes beyond the lower end of the convex post.

[0008] According to some embodiments of the present invention, the annular portion is located at the edge of the bottom wall, and the heat dissipation cavity is formed between the annular portion and the protruding post.

[0009] According to some embodiments of the present invention, the bottom wall of the air passage is provided with a support column, and the support column protrudes upward.

[0010] According to some embodiments of the present invention, in the vertical direction, the upper end of the support column protrudes beyond the upper opening of the air passage groove; or in the vertical direction, the upper end of the support column is located below the upper opening of the air passage groove or is flush with the upper opening of the air passage groove.

[0011] According to some embodiments of this utility model, the height H of the upper end of the support column protruding from the upper opening of the air passage groove in the vertical direction satisfies: 0mm < H ≤ 5mm.

[0012] According to some embodiments of the present invention, the upper end surface of the bottom wall is provided with a protrusion, the protrusion is arranged around the air passage groove, and the protrusion is used to abut against the carbon block.

[0013] According to some embodiments of the present invention, the bottom wall is provided with an annular groove, which is arranged around the edge of the bottom wall.

[0014] According to some embodiments of the present invention, the perimeter is provided with vertical holes and horizontal holes arranged at intervals, the vertical holes extending in the vertical direction and the horizontal holes extending in the circumferential direction of the perimeter.

[0015] The Arabian hookah according to a second aspect of the present invention includes the carbon box described in the above embodiment.

[0016] The Arabian hookah according to the embodiments of this utility model has at least the following beneficial effects: By employing the charcoal box of the first embodiment, the charcoal box features a receiving cavity formed by the surrounding edge and the bottom wall. The traditional central convex pillar structure is eliminated within the receiving cavity, resulting in a complete and spacious internal space. This allows users to easily insert charcoal blocks of different sizes or irregular shapes, improving ease of use. Furthermore, by forming a heat dissipation cavity below the bottom wall, when the charcoal box is placed on the bowl of an Arabic hookah, this cavity creates a heat buffer and distribution area between the bottom wall and the bowl. The heat generated by the burning charcoal is first conducted to this heat dissipation cavity, and then radiated and transferred more evenly downwards through the air medium within the cavity. This effectively avoids the problem of excessively high local temperatures caused by direct heat contact, ensuring that the hookah tobacco paste is heated evenly, thereby improving the stability of the smoke production and the flavor of the hookah.

[0017] Additional aspects and advantages of this invention will be set forth in part in the description which follows, and in part will be obvious from the description, or may be learned by practice of the invention. Attached Figure Description

Detailed Implementation

[0020] The embodiments of this utility model are described in detail below. Examples of these embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals denote the same or similar elements or elements having the same or similar functions throughout. The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain this utility model, and should not be construed as limiting this utility model.

If "first" or "second" is used in the description, it is only for the purpose of distinguishing technical features and should not be construed as indicating or implying relative importance, or implicitly indicating the number of indicated technical features, or implicitly indicating the order of the indicated technical features.

[0023] In the description of this utility model, unless otherwise explicitly defined, terms such as "setting," "installation," and "connection" should be interpreted broadly, and those skilled in the art can reasonably determine the specific meaning of the above terms in this utility model in conjunction with the specific content of the technical solution.

[0024] In existing technology, the bottom of the charcoal box in a hookah typically has a central protrusion to support the charcoal block. However, this structure takes up space, making it difficult to place large or irregularly shaped charcoal blocks, thus affecting ease of use. When a user attempts to place the charcoal block, the central protrusion can easily interfere with the edge of the charcoal block, causing it to tilt or fail to fall completely to the bottom, thus affecting the combustion effect.

[0025] To solve the above problems, refer to Figure 1 , Figure 2 , Figure 3 and Figure 4 As shown in the embodiment of this utility model, the carbon box 100 includes a surrounding edge 110 and a bottom wall 120. The surrounding edge 110 is arranged around and connected to the edge of the bottom wall 120. The surrounding edge 110 and the bottom wall 120 enclose a receiving cavity 121. A heat dissipation cavity 123 is formed below the bottom wall 120. A portion of the bottom wall 120 is recessed downward to form an air passage groove 131. The side wall of the air passage groove 131 is provided with a through hole 132. The receiving cavity 121, the air passage groove 131, the through hole 132 and the heat dissipation cavity 123 are connected in sequence.

[0026] The surrounding edge 110 refers to the annular sidewall structure extending around the edge of the bottom wall 120, forming the vertical boundary of the receiving cavity 121. The bottom wall 120 refers to the planar structure connected to the bottom of the surrounding edge 110, forming the bearing surface of the receiving cavity 121. The surrounding edge 110 and the bottom wall 120 are integral parts and can be manufactured by casting. The air passage groove 131 refers to the groove-shaped structure formed by a partial recess in the bottom wall 120. A recessed area can be formed in the bottom wall 120 using a mold, forming an independent airflow channel. The through hole 132 refers to the through hole opened in the sidewall of the air passage groove 131, which can be manufactured by drilling or punching to realize gas exchange between the receiving cavity 121 and the air passage groove 131.

[0027] By setting up a receiving cavity 121 enclosed by the surrounding edge 110 and the bottom wall 120, the traditional central protruding pillar 130 structure is eliminated inside the receiving cavity 121, making the internal space complete and open. This allows users to directly insert charcoal blocks of different sizes or irregular shapes, improving ease of use. Furthermore, by forming a heat dissipation cavity 123 below the bottom wall 120, when the charcoal box 100 is placed on the bowl 200 of the hookah 1000, this heat dissipation cavity 123 creates a heat buffer and distribution area between the bottom wall 120 and the bowl 200. The heat generated by the burning charcoal blocks can first be conducted to this heat dissipation cavity 123, and then radiated and transferred more evenly downwards through the air medium within the cavity. This effectively avoids the problem of excessively high local temperatures caused by direct heat contact, ensuring that the hookah tobacco paste is heated evenly, thereby improving the stability of smoke production and the flavor of the hookah.

[0028] Reference Figure 2 and Figure 4 As shown in the embodiment of this utility model, the bottom wall 120 of the air passage 131 is provided with a support column 133, which protrudes upward. The support column 133 refers to the protruding structure extending upward from the bottom wall 120 of the air passage 131. It can be a columnar boss integrally formed with the bottom wall 120, used to support the carbon block and physically isolate the carbon block from the opening 1311 of the air passage 131.

[0029] For example, the perimeter 110 and the bottom wall 120 together define a receiving cavity 121 for accommodating charcoal blocks. The recessed structure of the air passage 131 forms a sunken area in the bottom wall 120, and the support column 133 extends upward from the bottom of the air passage 131 to a predetermined height. When the charcoal block is placed in the receiving cavity 121, its bottom edge contacts the top of the support column 133, forming a suspended support state. The hot airflow generated by combustion enters the air passage 131 through the through hole 132 and flows downward along the recessed channel, thereby heating the hookah paste in the tobacco bowl 200 and causing the hookah paste to burn. The height setting of the support column 133 ensures that the bottom surface of the charcoal block maintains a distance from the opening 1311 of the air passage 131, preventing the charcoal block from completely covering the opening 1311 and obstructing the airflow.

[0030] This design integrates the support structure within the air passage 131, retaining its support function while creating an independent airflow path through the recessed channel. Simultaneously, the localized design of the support column 133 avoids the encroachment of a traditional integral boss on the receiving cavity 121, allowing for stable placement of charcoal blocks of different sizes. This design also achieves synergistic optimization of charcoal block placement stability and airflow channel unobstructedness. While physically isolating the charcoal block from the opening 1311 of the air passage 131, the support column 133 allows hot airflow to enter the recessed channel through the through-hole 132, forming a stable thermal convection path. This structure prevents the charcoal block from blocking the airflow channel due to gravity, ensuring continuous air circulation during combustion and maintaining uniform heating of the hookah tobacco paste.

[0031] Reference Figure 4 As shown, in an embodiment of the present invention, a portion of the bottom wall 120 protrudes outward to form a protruding post 130, an air passage groove 131 is formed inside the protruding post 130, and an annular portion 122 is formed on the lower bottom surface of the bottom wall 120. The annular portion 122 is arranged around the protruding post 130, and along the direction of gravity, the lower end of the annular portion 122 protrudes from the lower end of the protruding post 130.

[0032] The annular portion 122 refers to the annular protrusion protruding from the bottom surface of the bottom wall 120. It can be integrally formed with the bottom wall 120. It is arranged around the protrusion 130 and extends beyond the bottom of the protrusion 130, so that when the carbon box 100 is placed, the annular portion 122 will first contact the support surface of the tobacco bowl 200, thus preventing the protrusion 130 from blocking the air inlet of the tobacco bowl 200.

[0033] For example, after the bottom wall 120 protrudes outward to form a protruding post 130, the air passage 131 is built into the inside of the protruding post 130, so that the channel structure of the air passage 131 extends upward to the bottom of the receiving cavity 121. An annular portion 122 is provided on the lower surface of the bottom wall 120, so that under the direction of gravity, the lower end of the annular portion 122 is lower than the lower end of the protruding post 130. When the charcoal box 100 is placed on the tobacco bowl 200, the annular portion 122 first contacts the edge of the tobacco bowl 200 to provide support, while the lower end of the protruding post 130 is suspended and does not contact the tobacco bowl 200. Therefore, the lower end of the protruding post 130 will not interfere with the stability of the charcoal box 100, while the air passage 131 can still maintain communication with the receiving cavity 121 through the inside of the protruding post 130.

[0034] In this design, the lower end of the annular portion 122 preferentially contacts the supporting surface, while the lower end of the protruding column 130 is suspended, resulting in a more even distribution of the overall center of gravity of the carbon box 100 and avoiding instability caused by localized stress on the protruding column 130. When using the carbon box 100, the annular portion 122 preferentially contacts the supporting surface of the tobacco bowl 200, preventing the protruding column 130 from blocking the air inlet of the tobacco bowl 200. This solves the problem of poor stability caused by the lower end of the protruding column 130 contacting the supporting surface in existing carbon boxes 100, ensuring even stress distribution when the carbon box 100 is placed.

[0035] Reference Figure 3 As shown in the embodiment of this utility model, the annular portion 122 is located at the edge of the bottom wall 120, and a heat dissipation cavity 123 is formed between the annular portion 122 and the protrusion 130. The side wall of the air passage 131 is provided with a plurality of through holes 132 evenly distributed in the circumferential direction, which cooperate with the heat dissipation cavity 123 to improve the heat output uniformity.

[0036] The heat dissipation cavity 123 refers to the cavity structure formed between the annular portion 122 and the protrusion 130. It can be achieved by adjusting the distance between the annular portion 122 and the protrusion 130, and is used to provide space for heat diffusion. The through hole 132 refers to the holes evenly opened on the side wall of the air passage 131. It can be implemented by using circular or rectangular holes distributed at equal angles, and is used to guide airflow evenly into the heat dissipation cavity 123.

[0037] For example, the annular portion 122 is disposed at the edge of the bottom wall 120, forming a heat dissipation cavity 123 surrounding the protruding post 130. Multiple through holes 132 on the sidewall of the air passage 131 are evenly distributed circumferentially, allowing airflow to enter the heat dissipation cavity 123 uniformly. After heat is transferred to the heat dissipation cavity 123 through the through holes 132, it diffuses uniformly within the cavity structure, preventing localized overheating or underheating. The heat dissipation cavity 123 and the through holes 132 cooperate to form a heat conduction path, ensuring uniform heat distribution when heat is transferred from the air passage 131 to the outside of the carbon box 100, thereby ensuring uniform heating of the hookah tobacco paste.

[0038] This solution utilizes the heat dissipation cavity 123 formed by the annular portion 122 and the protruding post 130, combined with the circumferentially evenly distributed through holes 132, to expand the heat diffusion range to the entire edge area of ​​the charcoal box 100, eliminating the temperature difference between the center and the edge, and solving the problem of incomplete combustion of hookah tobacco paste caused by uneven heating. The heat dissipation cavity 123 and the through holes 132 work together to ensure uniform heat distribution, ensuring that all areas of the hookah tobacco paste are heated simultaneously, avoiding local unburned or over-carbonized areas, while reducing smoke concentration fluctuations caused by temperature differences, thus improving the smoking experience.

[0039] Reference Figure 4As shown in the embodiment of this utility model, the sidewall structure of the heat dissipation cavity 123 is an arc-shaped surface 124 to guide heat downward flow. The arc-shaped surface 124 of the sidewall structure of the heat dissipation cavity 123 means that the inner wall surface of the heat dissipation cavity 123 has a curved transition shape, which can be achieved by molding or machining. The curved arc design can reduce the flow resistance of airflow at the sidewall and promote the downward conduction of heat along the sidewall. Guiding heat downward flow means that the structural characteristics of the arc-shaped surface 124 cause the heat generated by combustion to form a downward flow trend within the heat dissipation cavity 123, thereby preventing the disorderly diffusion of heat inside the carbon box 100.

[0040] For example, the heat dissipation cavity 123 is formed by the space between the protrusion 130 of the bottom wall 120 and the annular portion 122, and its sidewalls use an arc-shaped surface 124 instead of the traditional right angle or flat structure. When the heat generated by the combustion of the charcoal enters the heat dissipation cavity 123, the arc-shaped sidewalls reduce airflow disturbance, allowing the heat to flow naturally downwards along the arc-shaped surface 124 to the tobacco bowl 200 area. In this process, the heat distribution is uniform, avoiding excessively high local temperatures that could lead to incomplete combustion of the hookah tobacco paste.

[0041] Through the above technical solution, this solution solves the problem of incomplete combustion of hookah tobacco paste caused by uneven heat distribution in traditional charcoal boxes 100. The arc-shaped sidewall optimizes the heat flow direction, ensuring efficient heat transfer to the tobacco bowl 200, while reducing heat retention in the heat dissipation cavity 123, thereby improving combustion efficiency and user experience.

[0042] Reference Figure 4 As shown in the embodiment of this utility model, along the vertical direction, the upper end of the support column 133 protrudes beyond the upper opening 1311 of the air passage groove 131, which can support the charcoal block and ensure that the charcoal block does not block the opening 1311 of the air passage groove 131, thus facilitating airflow during smoking. Alternatively, along the vertical direction, the upper end of the support column 133 is located below or flush with the upper opening 1311 of the air passage groove 131. The upper opening 1311 of the air passage groove 131 refers to the opening 1311 area at the top of the air passage groove 131 that communicates with the receiving cavity 121. This can be achieved by forming a recessed structure through stamping or casting processes, used to guide air into the receiving cavity 121.

[0043] When the upper end of the support column 133 protrudes beyond the opening 1311 of the air passage groove 131, the charcoal block is supported and a gap is formed between it and the opening 1311. The heat generated by combustion enters the inner cavity of the air passage groove 131 through the gap, preventing the charcoal block from completely covering the opening 1311 and thus obstructing the airflow. When the upper end of the support column 133 is flush with or lower than the opening 1311, the bottom wall 120 will be provided with other support structures to prevent the charcoal block from covering the opening 1311. At the same time, the support column 133 can still support the charcoal block and prevent the charcoal block from sliding and blocking the opening 1311.

[0044] In this design, the height of the support column 133 can be adapted to different charcoal block shapes, preventing the charcoal block from completely blocking the opening 1311 while also avoiding placement difficulties due to excessive height. For example, when the edges of the charcoal block are uneven, a flush support column 133 can provide multi-point support to prevent tilting, while a protruding support column 133 forces the formation of an airflow gap, solving the problem of the charcoal block easily clogging the air passage 131 opening 1311 when placed. Through the two implementation methods of selectable support column 133 height, the charcoal block is placed stably while maintaining an airflow path, avoiding a decrease in smoke generation efficiency caused by incomplete combustion or poor airflow.

[0045] Reference Figure 4 As shown in the embodiment of this utility model, the upper end of the support column 133 protrudes above the upper opening 1311 of the air passage groove 131 by a height H in the vertical direction, satisfying 0mm < H ≤ 5mm. For example, the value of H can be 1mm, 2mm, 3mm, 4mm, 5mm, etc. The height H refers to the vertical distance between the top of the support column 133 and the edge of the opening 1311 of the air passage groove 131. It can be achieved by adjusting the axial length of the support column 133, and its function is to balance the support effect and the convenience of carbon block placement.

[0046] For example, the top of the support column 133 is configured to protrude at a specific height, so that the charcoal block is stably supported when placed, preventing it from completely covering the opening 1311 of the air passage 131. When H is within the above range, a stable airflow channel is formed between the bottom of the charcoal block and the opening 1311 of the air passage 131, while the protrusion of the support column 133 is limited to the space that the charcoal block can accommodate, preventing the charcoal block from tilting or failing to be fully embedded in the receiving cavity 121 due to excessive height.

[0047] This solution, by limiting the height of the support column 133 to a reasonable range, ensures the separation of the carbon block from the opening 1311 of the air passage 131, and avoids spatial interference when the carbon block is placed. It solves the problems of poor placement stability and airflow obstruction caused by improper support structure height, and improves the compatibility of the carbon box 100 with carbon blocks of different sizes.

[0048] Reference Figure 2 and Figure 4As shown in the embodiment of this utility model, the upper end surface of the bottom wall 120 is provided with a protrusion 125. The protrusion 125 is arranged around the air passage groove 131. The protrusion 125 is used to abut against the charcoal block to prevent the charcoal block from completely adhering to the bottom wall 120, which would lead to incomplete combustion. The protrusion 125 refers to a local raised structure provided on the surface of the bottom wall 120. It can be implemented by using an annular boss or intermittently distributed protrusions. The height of the protrusion 125 can be adjusted to meet the support requirements of different charcoal blocks. Arranging it around the air passage groove 131 means that the protrusion 125 is continuously or intermittently arranged along the outer contour of the air passage groove 131 to form a support structure around the air passage groove 131, such as using concentric rings or symmetrical polygonal layout.

[0049] For example, when the charcoal block is placed inside the charcoal box 100, its bottom surface contacts the protrusion 125, while a gap is formed between the remaining area of ​​the bottom wall 120 and the charcoal block. This gap allows air to enter the receiving cavity 121 through the air passage 131 and diffuse outward through the through hole 132. The supporting effect of the protrusion 125 on the charcoal block prevents the charcoal block from sinking under gravity and completely covering the opening 1311 of the air passage 131, while also avoiding large-area contact between the bottom surface of the charcoal block and the bottom wall 120, which could lead to localized oxygen deficiency.

[0050] This solution adopts a protrusion 125 structure surrounding the air passage 131, which can form multi-point support in the edge area of ​​the charcoal block. This ensures that the charcoal block is placed stably and avoids the support structure from occupying too much space in the receiving cavity 121. It solves the problem of incomplete combustion caused by the charcoal block being completely attached to the bottom wall 120. The gap formed by the protrusion 125 maintains air circulation at the bottom of the charcoal block, so that the heat generated by combustion is evenly transferred to the hookah tobacco paste, while preventing the charcoal block from extinguishing due to excessive contact area.

[0051] Reference Figure 2 and Figure 4 As shown in the embodiment of this utility model, the carbon box 100 includes a bottom wall 120 and a surrounding edge 110. An annular groove 126 is provided at the connection between the bottom wall 120 and the surrounding edge 110. The annular groove 126 is arranged around the edge of the bottom wall 120. The annular groove 126 is used to collect carbon ash and reduce the amount of carbon ash entering the tobacco bowl 200.

[0052] The annular groove 126 refers to a recessed structure surrounding the edge of the bottom wall 120. It can be achieved by machining a groove at the connection between the bottom wall 120 and the surrounding edge 110. It is used to collect the ash that falls during combustion and prevent it from scattering into the inside of the tobacco bowl 200. The connection between the bottom wall 120 and the surrounding edge 110 refers to the transition area where the two meet. It is usually connected by integral molding or welding. The annular groove 126 forms a continuous groove structure at this point, which facilitates the centralized collection of ash.

[0053] For example, when the charcoal block burns in the receiving cavity 121, the resulting ash will fall downwards due to gravity or airflow. The annular groove 126 is arranged around the edge of the bottom wall 120 to intercept and contain the falling ash, preventing it from directly entering the bowl 200 and coming into contact with the hookah tobacco paste. Since the annular groove 126 is located at the junction of the bottom wall 120 and the surrounding edge 110, the ash is confined within the groove and will not diffuse to other areas with the airflow.

[0054] This solution, by adding an annular groove 126, concentrates the carbon ash in a specific area, significantly reducing the possibility of carbon ash diffusion. This solution effectively collects the carbon ash generated during combustion, preventing it from entering the inside of the tobacco bowl 200, thereby maintaining the cleanliness of the hookah tobacco paste, reducing smoke odor or incomplete combustion problems caused by carbon ash contamination, and also reducing the frequency of cleaning the tobacco bowl 200 for the user.

[0055] Reference Figure 2 As shown in the embodiment of this utility model, the perimeter 110 is provided with vertical holes 112 and horizontal holes 111. The vertical holes 112 extend in the vertical direction, and the horizontal holes 111 extend in the horizontal direction. There are multiple vertical holes 112, among which two vertical holes 112 form a vertical hole group 113. The two vertical holes 112 in the vertical hole group 113 are arranged side by side at intervals along the circumference of the perimeter 110. There are at least two horizontal holes 111, among which two horizontal holes 111 are arranged opposite to each other. The vertical hole group 113 and the horizontal holes 111 are used for ventilation. The side-by-side arrangement of the vertical hole group 113 can be adapted to be held by tweezers, while the opposite arrangement of the horizontal holes 111 can be adapted to be held by clips.

[0056] The vertical holes 112 are holes extending vertically along the perimeter 110. These can be implemented using rectangular or elliptical through-holes 132, with their vertical extension direction aligned with the direction of gravity, facilitating insertion and fixation of the tweezers. The horizontal holes 111 are holes extending horizontally along the perimeter 110. These can be implemented using circular or square through-holes 132, with their horizontal extension direction parallel to the circumferential tangent of the perimeter 110, facilitating insertion and fixation of the clamps when held laterally. The vertical hole group 113 consists of two vertical holes 112 spaced apart and arranged side-by-side along the perimeter 110, symmetrically distributed with a spacing of 3–8 mm. The gap between the two vertical holes 112 allows for insertion and clamping of the tweezers tip. The oppositely arranged horizontal holes 111 are two horizontal holes 111 located symmetrically along the perimeter 110, symmetrically distributed along the diameter of the perimeter 110. The clamping point formed by the two horizontal holes 111 can be adapted to the jaw width of the clamps.

[0057] For example, the circumferentially distributed vertical holes 112 and horizontal holes 111 of the perimeter 110 provide channels for air circulation, improving the oxygen supply efficiency during combustion. The vertical hole group 113 forms a clamping area by being arranged side by side at intervals. The tip of the tweezers can be inserted into the gap between two vertical holes 112 and clamp the perimeter 110 to achieve stable gripping. The horizontal holes 111 form clamping points by being symmetrically distributed. The jaws of the clamps can be inserted into the horizontal holes 111 and clamp the perimeter 110, thereby adapting to clamps of different shapes and sizes.

[0058] In some specific embodiments, the vertical hole group 113 can be arranged symmetrically on both sides of the perimeter 110, and the horizontal hole 111 can be arranged symmetrically at the front and back of the perimeter 110 to accommodate multi-angle clamping requirements. The height of the vertical hole 112 can be 1 / 3 to 2 / 3 of the height of the perimeter 110, and the diameter of the horizontal hole 111 can be 2 to 4 mm to meet the insertion requirements of different clamps.

[0059] This design, through the layout of vertical holes 112 and horizontal holes 111, avoids interference with the placement of the carbon block by the structure. The hole design in different directions accommodates both tweezers and clips, solving the problem of the single clamping method of the traditional carbon box 100. It achieves compatibility between the carbon box 100 and various clamps, avoiding carbon block falling off or shifting position due to unstable clamping. At the same time, the ventilation hole design optimizes combustion efficiency and ensures that the hookah tobacco paste is heated evenly.

[0060] Reference Figure 1 As shown in the embodiment of this utility model, the Arabic hookah 1000 includes a bowl 200, a charcoal box 100, a water container 300, and a mouthpiece 400. The charcoal box 100 is installed on the upper end of the bowl 200. The charcoal box 100 includes a rim 110 and a bottom wall 120. The rim 110 surrounds and connects to the edge of the bottom wall 120 to form a receiving cavity 121. A portion of the bottom wall 120 is recessed outward to form an air passage groove 131. The inner cavity of the air passage groove 131 communicates with the receiving cavity 121. The side wall of the air passage groove 131 is provided with a through hole 132. The bottom wall 120 of the air passage groove 131 is provided with an upwardly protruding support post 133. The water container 300 is connected to the bowl 200, and the mouthpiece 400 is connected to the water container 300. It is used to draw air through the mouthpiece 400, so that the airflow passes through the carbon box 100, the bowl 200 and the water inside the water container 300. At the same time, the airflow also carries the smoke produced by the burning hookah paste, which is then passed through the water and provided to the user for inhalation.

[0061] The bowl 200 is a container for holding the hookah tobacco paste. It can be made of high-temperature resistant ceramic or metal. Its internal space is connected to the receiving cavity 121 of the charcoal box 100 through an air passage 131 to achieve heat transfer and airflow circulation. The charcoal box 100 is installed on the top of the bowl 200, which means it is placed directly or fixed to the top of the bowl 200 by a snap-fit ​​structure. This ensures that the heat generated by combustion directly acts on the hookah tobacco paste, while preventing charcoal ash from falling into the bowl 200.

[0062] For example, the charcoal box 100 forms a communication channel with the tobacco bowl 200 through the air passage 131 of the bottom wall 120. The hot air generated by combustion enters the heat dissipation cavity 123 through the through hole 132, and then enters the tobacco bowl 200 through the air passage 131. The support column 133 lifts the charcoal block, creating a gap between it and the bottom wall 120, preventing the charcoal block from blocking the opening 1311 of the air passage 131, while allowing air to enter through the through hole 132 and make full contact with the charcoal block. The perimeter 110 of the charcoal box 100 is provided with a set of vertical holes 113 and horizontal holes 111 to accommodate different clamps. For example, tweezers can be inserted into the side-by-side set of vertical holes 113, and clamps can hold the opposite horizontal holes 111, thereby improving the ease of operation.

[0063] This design, through the protruding support column 133 and the recessed air passage 131, expands the effective space of the receiving cavity 121 while avoiding blockage, allowing larger or irregularly shaped charcoal blocks to be placed stably. Furthermore, the cooperation between the heat dissipation cavity 123 and the through hole 132 optimizes heat distribution, reducing the problem of uneven combustion of hookah tobacco paste caused by localized overheating.

[0064] Through the above technical solution, this solution solves the problem that the charcoal block cannot be fully placed into the charcoal box 100 due to the obstruction of the central protrusion 130. The airflow channel is maintained unobstructed through the synergistic effect of the support column 133 and the air passage 131. At the same time, it adapts to the clamping requirements of various clamps, improving the stability of charcoal block placement and operational efficiency. Heat is evenly diffused through the heat dissipation cavity 123, ensuring that the hookah tobacco paste is heated evenly and reducing the probability of charcoal ash entering the tobacco bowl 200.

[0065] Since the Arabian hookah 1000 adopts all the technical solutions of the carbon box 100 of the above embodiments, it has at least all the beneficial effects brought about by the technical solutions of the above embodiments, which will not be repeated here.

[0066] The embodiments of the present utility model have been described in detail above with reference to the accompanying drawings. However, the present utility model is not limited to the above embodiments. Within the scope of knowledge possessed by those skilled in the art, various changes can be made without departing from the spirit of the present utility model.
