Description

Technical Field

[0001] This utility model relates to the field of food processing equipment, and in particular to a portable food smoker. Background Technology

[0002] Smokers are widely used to impart unique flavors to food in outdoor barbecues, sous-vide cooking, and professional catering settings. However, existing smokers generally rely on manual ignition or external spray guns for the ignition process, requiring users to repeatedly adjust the fuel position and airflow, making the operation cumbersome and time-consuming. Especially in humid or low-temperature environments, fuels such as sawdust / fruit wood pellets have difficulty quickly reaching a stable combustion temperature, resulting in a high ignition failure rate and directly affecting the subsequent smoking efficiency.

[0003] During combustion, fuels such as sawdust / fruit wood pellets tend to accumulate in the combustion chamber due to their varying particle size and humidity, clogging the air intake passage and causing intermittent flameout and reduced firepower. This wastes fuel and requires frequent disassembly and cleaning. At the same time, most existing exhaust outlets are fixed short pipes, and the direction of flue gas flow is significantly affected by wind direction and equipment placement angle, making it difficult to achieve stable connection with ovens, smokehouses, or vacuum sous-vide equipment of different diameters, resulting in flue gas leakage and flavor loss.

[0004] To achieve continuous feeding and uniform combustion, traditional smokers often require multiple mixing chambers and complex spiral, gear, or pneumatic propulsion systems. These mechanisms not only make the overall structure bulky and large, but also, because the fuel pressure plate and transmission components are constantly exposed to a high-temperature tar environment, they are prone to jamming, deformation, or even breakage, resulting in a high maintenance rate. In addition, the multi-chamber design leads to a significant increase in the number of parts, requiring users to complete multiple alignment, locking, and connection steps before each use, which is time-consuming and labor-intensive. During disassembly and cleaning, oil stains and tar residue in narrow chambers and dead corners are difficult to remove completely, further increasing the difficulty of maintenance.

It uses an integrated metal cylindrical combustion chamber as its core, eliminating multiple chambers and booster mechanisms. Through a smoke-oxygen mixing tube and an electric air pump, it achieves easy ignition, complete combustion, and adjustable smoke. The overall structure is simple and reliable, lightweight, significantly reducing costs and improving compatibility and portability.

[0006] To achieve the above objectives, the present invention adopts the following technical solution:

[0008] A combustion device for containing and burning smoke fuel includes a metal combustion cylinder, a smoke-oxygen mixing pipe, and smoke guide plates; the interior of the metal combustion cylinder forms a fuel combustion space; the smoke-oxygen mixing pipe extends axially along the metal combustion cylinder and communicates with the combustion space to introduce air for combustion support; the smoke guide plates are located on the flue gas outlet side of the metal combustion cylinder to isolate the smoke oil and guide the direction of the flue gas flow.

[0009] An air pump, independent of the combustion device, is used to provide a controllable airflow to the combustion device;

[0010] An air inlet pipe is connected between the air pump and the combustion device to deliver the airflow generated by the air pump into the metal combustion cylinder.

[0011] The exhaust pipe is connected to the exhaust outlet of the combustion device to guide the exhaust gas generated by combustion to the external grilling equipment;

[0012] The air pump, air inlet pipe, combustion device, and smoke outlet pipe are sequentially connected by airflow to form a complete flue gas generation and delivery path.

[0013] As a preferred embodiment: the flue gas-oxygen mixing tube includes a mixing tube body and a smoke outlet plate. The mixing tube body is hollow inside, and a pull ring for easy handling is provided at the top of the mixing tube body. Multiple through holes for maintaining the flow of oxygen and flue gas are provided on the outer wall of the mixing tube body. The smoke outlet plate includes a base plate and side plates inclined upward from both sides of the base plate. The lower end of the mixing tube body is fixed through the base plate. The side plates are detachably clamped to the inner wall of the metal combustion cylinder. The flue gas-oxygen mixing tube is detachably clamped to the inner wall of the metal combustion cylinder through the side plates. The base plate and the side plates divide the metal combustion cylinder into an upper chamber for fuel combustion and a lower chamber for flue gas storage, and multiple smoke outlet holes are provided on the side plates.

[0014] As a preferred embodiment: the smoke guide plate is located in the lower chamber and includes an integrally connected top plate, a vertical plate and a connecting piece. The connecting piece is detachably installed on the inner wall of the metal combustion cylinder. The vertical plate is vertically connected to the connecting piece and has multiple smoke passage holes hollowed out on the vertical plate. The top plate is horizontally connected to the top of the vertical plate and is located at intervals below the bottom plate of the smoke guide plate.

[0015] As a preferred embodiment: the air inlet pipe and the smoke outlet pipe are respectively connected to the lower chamber, and the air inlet pipe and the smoke outlet pipe are opposite to each other and located below the top plate of the smoke guide plate.

[0016] As a preferred embodiment, the metal combustion cylinder has an openable and screw-on top cover at the upper end and a removable bottom cover at the lower end.

[0017] As a preferred embodiment: the top cover has a hollow heat-proof structure at its center, the hollow heat-proof structure includes a connecting column extending downward from the center of the top cover and a heat insulation plate installed at the lower end of the connecting column, and a heat insulation cavity is formed between the heat insulation plate and the top cover; the upper surface of the top cover is also provided with a handle for easy opening and feeding and to prevent burns.

[0018] As a preferred embodiment: the outer wall of the air pump is provided with a knob for controlling the air supply and indirectly adjusting the combustion temperature and smoke output of the combustion device, as well as a Type-C power interface; and an oil-proof and waterproof bracket is also provided on the top of the air pump.

[0022] Compared with the prior art, this utility model has obvious advantages and beneficial effects. Specifically, as can be seen from the above technical solution, by taking "integrated metal cylindrical combustion chamber + electric air pump" as the core, the multiple mixing chambers and complex booster mechanisms required by traditional smokers are eliminated: the top cover of the cylinder is screwed on to achieve rapid loading and feeding, and the smoke-oxygen mixing pipe added inside the cylinder makes ignition easier and fuel combustion more complete; the electric air pump outputs smoke stably through the air inlet pipe and smoke outlet pipe, and the smoke size can be precisely controlled with the adjustable knob. At the same time, the anti-scalding handle and pull handle play a role in preventing scalding and heat insulation. The overall structure is simple and reliable, and the size and weight are significantly reduced.

[0023] In terms of interface and maintenance, the product adopts a modular cylinder-oxygen mixing tube combination, which can be quickly connected to various ovens, smokehouses or low-temperature cooking equipment through universal connectors; disassembly and assembly only require unscrewing the connecting screws and pulling out the oxygen mixing tube connected by the pull ring. Cleaning and storage can be completed without tools, which fundamentally avoids common problems such as fuel pressure plate jamming and dead corner oil accumulation. It not only improves assembly efficiency but also reduces manufacturing costs, realizing a lightweight, flexible and compatible portable smoking solution.

[0034] This utility model is as follows Figures 1 to 7 As shown, a portable food smoker includes a combustion device 10, an air pump 20, an air inlet pipe 30, and a smoke outlet pipe 40, wherein:

[0035] The combustion device 10 is used to contain and burn smoke fuel, and includes a metal combustion cylinder 11, a smoke-oxygen mixing pipe 12, and a smoke guide plate 13.

[0036] The metal combustion cylinder 11 forms a fuel combustion space 111 (the fuel is usually smoked wood chips or fruit wood pellets). The upper end of the metal combustion cylinder 11 is provided with an openable and screw-on top cover 112, which allows for easy replenishment of fuel into the metal combustion cylinder 11. The lower end is provided with a detachable bottom cover 113, which has a simple structure and is convenient for loading and unloading. The top cover 112 has a hollow heat-insulating structure 1121 in the center. The hollow heat-insulating structure 1121 includes a connecting post 1122 extending downward from the center of the top cover 112 and a heat insulation plate 1123 installed at the lower end of the connecting post 1122. A heat insulation cavity 1124 is formed between the heat insulation plate 1123 and the top cover 112. The heat insulation cavity 1124 can isolate part of the heat in the combustion space 111, preventing people from being burned when they touch the top cover 112. The upper surface of the top cover 112 is also provided with a handle 114 for easy opening and feeding and to prevent burns. The top cover 112 is designed to allow users to quickly add fuel during use, while preventing the spillage of hot fuel from causing danger.

[0037] The bottom cover 113 has a recessed receiving groove 1131, in which a receiving component for absorbing combustion fumes and holding combustion residue can be replaced. The receiving component can be oil-absorbing paper, which can absorb the fumes produced by fuel combustion, minimizing the amount of fumes that reach the food through the exhaust pipe 40. It should be noted that the receiving component is not limited to oil-absorbing paper; it can also be made of other high-temperature resistant materials, while also serving the functions of collecting residue, easy replacement, and easy cleaning.

[0038] The air pump 20 is provided with an anti-slip bracket 21 at its bottom. The anti-slip bracket 21 is detachably connected to the outer wall of the metal combustion cylinder 11 by screws. The lower surface of the anti-slip bracket 21 is provided with an anti-slip pad, which can increase the friction between the air pump 20 and the support platform, improve the stability of the placement, and make the smoke generator safer to use.

[0039] The oxygen-smoke mixing tube 12 extends axially along the metal combustion chamber 11 and communicates with the combustion space 111 to introduce air for combustion support. Specifically, the oxygen-smoke mixing tube 12 includes a mixing tube body 121 and a smoke outlet plate 122. The mixing tube body 121 is hollow inside, and a pull ring 123 for easy handling is provided at the top of the mixing tube body 121. Multiple through holes 124 (round holes, strip holes, or other shapes) are provided on the outer wall of the mixing tube body 121 to allow oxygen and smoke to flow. The smoke outlet plate 122 includes a base plate 1221 and side plates 1222 inclined upward from both sides of the base plate 1221. The lower end of the mixing tube body 121 is fixed through the base plate 1221, and the side plates 1222 are detachably clamped to the metal combustion chamber 11. On the inner wall, the flue gas mixing pipe 12 is detachably engaged with the inner wall of the metal combustion cylinder 11 via the side plate 1222. The bottom plate 1221 and the side plate 1222 divide the metal combustion cylinder 11 into an upper chamber 115 (combustion space 111) for fuel combustion and a lower chamber 116 for flue gas storage. Multiple smoke outlet holes 1223 are provided on the side plate 1222. The flue gas generated in the combustion space 111 enters the lower chamber 116 through the smoke outlet holes 1223 and is blown out to the smoke outlet pipe 40 through the air inlet pipe 30. During the air intake process of the air inlet pipe 30, oxygen will enter the combustion space 111 from the lower end of the mixing pipe 121 through the through hole 124 on the outer wall of the mixing pipe 121 to promote fuel combustion and make the fuel combustion more complete. The side plate 1222 is inclined upwards, which not only ensures a stable contact between the side plate 1222 and the inner wall of the metal combustion cylinder 11, but also reduces the possibility of the smoke outlet 1223 on the side plate 1222 being blocked by fuel, thus improving the flow of flue gas. An ignition hole 117 communicating with the interior and a heat-resistant handle 118 are provided on the outer wall of the metal combustion cylinder 11. The gripping part of the heat-resistant handle 118 is spaced apart from the outer wall of the metal combustion cylinder 11 to prevent burns from handheld use.

[0040] The smoke guide plate 13 is located on the side of the flue gas outlet 14 of the metal combustion cylinder 11, and is used to isolate the grease and guide the flow of flue gas. In this embodiment, the smoke guide plate 13 is located in the lower chamber 116, and includes an integrally connected top plate 131, a vertical plate 132 and a connecting piece 133. The connecting piece 133 is detachably installed on the inner wall of the metal combustion cylinder 11 by screws. The vertical plate 132 is vertically connected to the connecting piece 133, and multiple perforations are provided on the vertical plate 132. A smoke vent 134 is provided. The top plate 131 is horizontally connected to the top of the vertical plate 132 and is located at intervals below the bottom plate 1221 of the smoke outlet plate 122. The top plate 131 can catch the dripping soot in the combustion space 111. The soot flows with the vertical plate 132 to the receiving groove 1131 of the bottom cover 113, where it is absorbed by the receiving component. The smoke vent 134 on the vertical plate 132 guides the smoke and reduces the amount of soot entering the smoke outlet 14. The air inlet pipe 30 and the smoke outlet pipe 40 are respectively connected to the lower chamber 116 and are opposite to each other, located below the top plate 131 of the smoke guide plate 13. The airflow generated by the air pump 20 enters through the air inlet pipe 30 and can directly blow the smoke in the lower chamber 116 out through the smoke outlet pipe 40, reducing gas flow resistance and improving smoking efficiency.

[0041] The air pump 20, independent of the combustion device 10, is used to provide controllable airflow to the combustion device 10. The outer wall of the air pump 20 is equipped with a knob 22 for controlling air supply and indirectly adjusting the combustion temperature and smoke output of the combustion device 10, as well as a Type-C power interface 23. Rotating the knob 22 adjusts the power of the air pump 20, changes the airflow speed, and increases or decreases the smoke output. The Type-C power interface 23 is used to connect a power source or power bank to power the air pump 20. An oil-proof and waterproof bracket 24 is provided on the top of the air pump 20. The oil-proof and waterproof bracket 24 is disc-shaped and covers the air pump 20 to shield it from smoke and water vapor, preventing them from entering the air pump 20.

[0042] The air intake pipe 30 connects the air pump 20 and the combustion device 10, delivering the airflow generated by the air pump 20 into the metal combustion cylinder 11. The interface of the air intake pipe 30 is made of high-temperature heat-resistant material, compatible with various barbecue equipment interfaces, and possesses good sealing and compatibility. Interface compatibility methods include: direct screwing of the external thread to the air intake hole of mainstream ovens; quick-connect buckles to adapt to silicone hoses, instantly connecting to smoke boxes of different diameters; and the inclusion of a stepped adapter for easy matching with large, medium, and small standard air ducts. The smoke outlet pipe 40 connects to the smoke outlet 14 of the combustion device 10, venting the smoke generated by combustion to external barbecue equipment. The air intake pipe 30 includes an intake metal pipe and an intake hose, and the smoke outlet pipe 40 includes an exhaust metal pipe and an exhaust hose. The metal pipe is used at the joint, and the hose is used for intermediate connections. Furthermore, the components of the air intake pipe 30 and the smoke outlet pipe 40 can be replaced with various materials (such as stainless steel, aluminum alloy, high-temperature resistant silicone, etc.) to meet different usage scenarios and cost control requirements. The air pump 20, air inlet pipe 30, combustion device 10 and smoke outlet pipe 40 are connected in sequence to form a complete flue gas generation and transportation path.

[0043] The working principle of the smoker is as follows: During use, the top cover 112 is opened, fuel is placed in the combustion space 111, and the fuel in the combustion space 111 is ignited using an igniter through the ignition hole 117. The flue gas generated by the fuel enters the lower chamber 116 downwards through the smoke outlet hole 1223 on the smoke outlet plate 122; the airflow generated by the air pump 20 enters the lower chamber 116 through the air inlet pipe 30, blowing the flue gas out through the flue gas outlet 14 and the smoke outlet pipe 40; during this process, the airflow from the air pump 20 also enters the mixing pipe 121 and mixes with the flue gas in the combustion space 111 to form a smoke-oxygen mixture, promoting more complete combustion of the fuel. Simultaneously, the smoke-oxygen mixing pipe 12 and the air pump 20 work together to adjust the concentration and stability of the output flue gas, improving the uniformity of the smoke. Furthermore, the airflow rate can be adjusted by rotating the knob 22 on the air pump 20, thereby adjusting the combustion temperature and smoke output to meet different smoke requirements.

[0044] The key design feature of this invention is that, by using an "integrated metal cylindrical combustion chamber + electric air pump" as its core, it eliminates the multiple mixing chambers and complex booster mechanisms required by traditional smokers: the top cover of the cylinder is screwed on to enable quick loading and feeding, and the addition of a smoke-oxygen mixing pipe inside the cylinder makes ignition easier and fuel combustion more complete; the electric air pump outputs smoke stably through the air inlet pipe and the smoke outlet pipe, and the amount of smoke can be precisely controlled by the adjustable knob. At the same time, the anti-scalding handle and pull handle provide anti-scalding and heat insulation functions. The overall structure is simple and reliable, and the size and weight are significantly reduced.

[0045] In terms of interface and maintenance, the product adopts a modular cylinder-oxygen mixing tube combination, which can be quickly connected to various ovens, smokehouses or low-temperature cooking equipment through universal connectors; disassembly and assembly only require unscrewing the connecting screws and pulling out the oxygen mixing tube connected by the pull ring. Cleaning and storage can be completed without tools, which fundamentally avoids common problems such as fuel pressure plate jamming and dead corner oil accumulation. It not only improves assembly efficiency but also reduces manufacturing costs, realizing a lightweight, flexible and compatible portable smoking solution.

[0046] The above description is merely a preferred embodiment of the present utility model and does not constitute any limitation on the technical scope of the present utility model. Therefore, any minor modifications, equivalent changes, and alterations made to the above embodiments based on the technical essence of the present utility model shall still fall within the scope of the technical solution of the present utility model.
