[0040] Reference below Figure 1-Figure 5 A household smoker according to an embodiment of the present invention is described.

[0041] like Figure 1-Figure 5 As shown, the household smoker includes a main unit 100 and a smoke duct 110. The smoke duct 110 is detachably connected to the main unit 100 and is made of food-grade silicone. The user inserts the nozzle of the smoke duct 110 into a smoke hood or a smoke bag to smoke food. The smoke duct 110 can be separated from the main unit 100 and replaced after aging due to long-term use.

[0042] The main unit 100 includes a smoke storage chamber 210, an air guide chamber 500, and a smoke mixing section 400. The smoke mixing section 400 is provided with a smoke inlet pipe 410 connected to the smoke storage chamber 210, an air guide pipe 420 connected to the air guide chamber 500, and a smoke exhaust pipe 430 connected to the smoke duct 110. The smoke storage chamber 210 is provided with a combustion chamber 310 that passes through the smoke storage chamber 210. The smoke material burns only in the combustion section 311 and produces smoke gas. The smoke gas generated by the combustion of the smoke material in the upper half of the combustion chamber 310 (i.e., the combustion section 311) enters the smoke storage chamber 210. The smoke material is placed in the combustion chamber 310 and burns to produce smoke gas. The blowing component 510 in the air guide chamber 500 generates a high-speed airflow and blows it into the air guide pipe 420.

[0043] Among them, the smoke inlet pipe 410 and the air guide pipe 420 are connected to each other, and the pipe wall of the smoke inlet pipe 410 and the pipe wall of the air guide pipe 420 are arranged at intervals; when the gas of the blowing assembly 510 is blown out from the air guide pipe 420, a negative pressure is formed around the air guide pipe 420, and the smoke gas in the smoke storage chamber 210 enters the smoke mixing part 400 through the smoke inlet pipe 410 and is blown out to the smoke exhaust pipe 430 along with the gas.

[0044] Specifically, before smoking food, the air blowing assembly 510 is turned on, and the air duct 420 blows out a high-speed airflow. At this time, the peripheral pressure of the high-speed airflow decreases, forming a pressure difference, causing the gas around the air duct 420 to converge into the high-speed airflow and enter the smoke exhaust pipe 430. At this time, the pressure in the smoke storage chamber 210 is greater than the pressure in the smoke mixing section 400, and the air in the smoke storage chamber 210 flows into the smoke mixing section 400 through the smoke inlet pipe 410. Because the combustion chamber 310 and the smoke storage chamber 210 are connected, the combustion chamber 310 is connected to the outside world. At this time, the air flows from the combustion chamber 310 to the smoke storage chamber 210, to the smoke mixing section 400, and then into the smoke duct 110, forming a unidirectional flow. It should be noted that the smoked material only burns in the upper half of the combustion chamber 310 (i.e., the combustion section 311) and generates smoke gas.

[0045] When the user ignites the smoking material in the combustion chamber 310, the smoke gases flow along the air flow into the smoke storage chamber 210, the smoke mixing unit 400, and the smoke duct 110, thus enabling the normal operation of the fumigator. Throughout the fumigation process, the high-speed airflow continuously blown out by the air duct 420 mixes with the smoke gases and enters the exhaust pipe 430. This effectively prevents the smoke gases from entering and corroding the blower assembly 510. The blower assembly 510 is physically separated from the smoke storage chamber 210 during the fumigation process, effectively preventing smoke gases from coming into contact with it, thereby effectively extending the life of the fumigator's components and the operating life of the device.

[0046] Currently, fans are used in the market to remove the fumes generated by burning materials from pipes using a centrifugal fan. The motor shaft and fan blades are located within the entire fumes path. Prolonged contact with fumes can cause corrosion to the motor shaft over time, leading to product failure.

[0047] Unlike existing solutions that use a centrifugal fan to drive the flow of fume gas, the air blowing assembly 510 of this embodiment utilizes an air pump, the air outlet of which is connected to the air duct 420. The high-speed airflow generated by the air pump propels the fume gas into the fume duct 110, eliminating the need for the air pump to come into direct contact with the fume gas. By utilizing a siphoning mechanism to deliver the fume gas, no working components come into contact with the gas, resulting in no wear and tear of the working components and a longer lifespan.

[0048] In other embodiments, the air blowing assembly 510 can also utilize a centrifugal fan, which, within the air guide chamber 500, passes the gas generated by the centrifugal fan into the air guide duct 420 via a pipe. The present invention primarily separates the fume gas from the air blowing assembly 510 through the fume mixing unit 400. The components of the air blowing assembly 510 do not need to operate within the smoke storage chamber 210, effectively preventing corrosion damage caused by the adhesion of smoke oil and other substances in the fume gas to the air blowing assembly 510 and its seals.

[0049] In some embodiments of the present invention, Figure 3-Figure 5 As shown, the flue gas mixing section 400 adopts a three-way structure, with the smoke inlet pipe 410, air duct 420, and smoke exhaust pipe 430 coaxially arranged. In this embodiment, the coaxial arrangement of the smoke inlet pipe 410, air duct 420, and smoke exhaust pipe 430 of the smoke mixing section 400 reduces gas flow transitions, allowing for more complete mixing of the fume gas and high-speed airflow. It also prevents fume gas from adhering to the inner walls of the smoke mixing section 400, facilitating later cleaning of the interior of the smoke mixing section 400. Specifically, the smoke exhaust pipe 430 and the smoke inlet pipe 410 share the same conduit, with the air duct 420 located within it.

[0050] In some embodiments of the present invention, Figure 3-Figure 5 As shown, the air duct 420 is disposed within the smoke inlet pipe 410, and an annular smoke inlet 440 is formed between the outer wall of the air duct 420 and the inner wall of the smoke inlet pipe 410. Specifically, the location of the air duct 420 within the smoke inlet pipe 410 increases the cross-sectional area of ​​the annular smoke inlet 440, allowing more smoke to enter, increasing the flow rate of smoke, and improving smoke efficiency.

[0051] It should be understood that disposing the air duct 420 inside the smoke inlet pipe 410 is not the only embodiment. In some other embodiments, the smoke inlet pipe 410 can also be disposed inside the air duct 420, that is, an annular air inlet is formed between the outer wall of the smoke inlet pipe 410 and the inner wall of the air duct 420, and the smoke gas is blown in from the middle and merged with the high-speed air flow toward the periphery. The smoke gas flow is small, which is suitable for food processing with a small smoke gas flow, such as being slightly drunk.

[0052] In a further embodiment, Figure 4 and Figure 5 As shown, the ratio of the width of the annular smoke inlet 440 to the radius of the air duct 420 is 0.8 to 2.0. In this embodiment, the smoke mixing unit 400 is integrally formed with the main unit 100. The cross-sectional area of ​​the annular smoke inlet 440 determines the flue gas flux, while the cross-sectional area of ​​the air duct 420 determines the high-speed airflow flux. Adjusting the cross-sectional area ratio of the annular smoke inlet 440 to the air duct 420 can adjust the mixing ratio of the flue gas and the high-speed airflow, achieving different smoking effects.

[0053] In other embodiments, the smoke mixing unit 400 and the main unit 100 are detachable, and smoke mixing units 400 of different specifications are provided with different gas mixing ratios. Users can select the smoke mixing unit 400 of corresponding specifications according to actual use needs.

[0054] In some embodiments of the present invention, Figure 3 and Figure 5 As shown, the opening of the air duct 420 near one end of the smoke exhaust pipe 430 is tapered and diffuse. Specifically, the high-speed airflow in the air duct 420 diffuses at the end of the opening and enters the smoke mixing section 400. At this time, the airflow volume in the smoke mixing section is large, creating a vacuum effect. This increases the pressure difference between the inside and outside of the smoke storage chamber 210 and the smoke mixing section 400, promoting the entry of smoke gas from the smoke storage chamber 210 into the smoke mixing section 400.

[0055] In some embodiments of the present invention, Figure 2-Figure 5 As shown, the oil storage cup 220 is provided in the smoke storage chamber 210 and below the combustion chamber 310. Specifically, the oil storage cup 220 is provided in the smoke storage chamber 210, with the opening of the oil storage cup 220 facing the combustion chamber 310. The smoke oil produced by combustion in the combustion chamber 310 drips into the oil storage cup 220, which collects the smoke oil, debris and other combustion products, preventing the combustion products from contaminating the smoke storage chamber 210 and making subsequent cleaning more convenient.

[0056] In some embodiments of the present invention, Figure 1-Figure 5As shown, the smoke storage chamber 210 includes a detachably connected metal cover 230, and the metal cover 230 is provided with a mounting base 231 that is in communication with the smoke storage chamber 210, and the mounting base 231 is detachably connected to the combustion chamber 310. Specifically, in this embodiment, the metal cover 230 has better heat resistance and heat dissipation performance, so that the smoker can be used for a long time. The metal cover 230 is screwed to the opening of the smoke storage chamber 210 by screws, so that the smoke storage chamber 210 forms a closed cavity. The combustion chamber 310 is mounted on the metal cover 230 through the mounting base 231. Specifically, the combustion chamber 310 is threadedly connected to the mounting base 231 by threads. The user cleans the interior of the smoke storage chamber 210 by removing the metal cover 230.

[0057] In other embodiments, the metal cover 230 and the smoke storage chamber 210 can be magnetically attached to each other through a magnetic structure, so that tool-free disassembly is achieved, making subsequent cleaning more convenient.

[0058] In some embodiments of the present invention, Figure 2-Figure 5 As shown, the metal cover 230 is provided with a limiting portion 232 on the side near the smoke storage chamber 210. When the metal cover 230 is connected to the smoke storage chamber 210, the limiting portion 232 fixes the position of the oil storage cup 220, preventing the oil storage cup 220 from moving. Specifically, the limiting portion 232 is integrally formed with the metal cover 230. The limiting portion 232 is arranged around the mounting base 231, and the side wall of the oil storage cup 220 abuts the side wall of the limiting portion 232. When the metal cover 230 and the smoke storage chamber 210 are properly installed, the position of the oil storage cup 220 in the smoke storage chamber 210 is fixed, preventing it from being installed incorrectly.

[0059] In some embodiments of the present invention, Figure 2-Figure 5 As shown, the combustion chamber 310 includes a bucket-shaped combustion portion 311 and a channel portion 312. One end of the channel portion 312 is connected to the smoke storage chamber 210, and the other end is connected to the combustion portion 311. The opening of the combustion portion 311 gradually narrows from the top toward the channel portion 312. Specifically, in this embodiment, the combustion chamber 310 is made of metal, which can withstand higher temperatures. The large opening at the top of the combustion chamber 310 makes it easier for users to place ignited smoking materials into the combustion portion 311.

[0060] In a further embodiment, the combustion portion 311 is provided with a metal screen 313. Specifically, the metal screen 313 is made of stainless steel, which is resistant to high temperatures and corrosion. The metal screen 313 is provided with mesh holes, and the smoke oil and debris fall into the oil storage cup 220 below through the mesh holes.

[0061] In some embodiments of the present invention, Figure 1 、 Figure 3 and Figure 4As shown, the main unit 100 is equipped with a power supply assembly 520 and a control panel 530. The control panel 530 is located on the side wall of the main unit 100 and is electrically connected to the power supply assembly 520 and the air blowing assembly 510. Specifically, the power supply assembly 520 uses an internal or external battery. The control panel 530 controls the operation of the smoker and powers the air pump of the air blowing assembly 510. The power supply structure used by the power supply assembly 520 is a technical solution well known to those skilled in the art and will not be described in detail in this embodiment.

[0062] In some embodiments of the present invention, Figures 1-4 As shown, the main unit 100 is tower-shaped, with the smoke storage chamber 210 located in the upper half of the main unit 100 and the air guide chamber 500 located in the lower half. Specifically, the smoker in this embodiment has a tower-shaped structure, with heavy components such as the air blowing assembly 510 and the power supply assembly 520 located in the lower half of the main unit 100. This lowers the center of gravity of the smoker and improves its operating stability.
