Description

Technical Field

[0001] The invention relates to the field of smoking, and in particular to a portable smoking machine. Background Art

[0002] Smoking is a common method used in food processing. Traditional smoking methods (such as manual smoking) are time-consuming and require individual food items to be processed individually, making this method inefficient for large-scale food processing. Consequently, a range of food smoking machines have emerged on the market. These machines vary in size for different food types, with some being larger for roasting chicken or duck and unsuitable for smoking smaller items like beverages or desserts.

[0003] Smoking small foods, such as drinks or desserts, adds a smoky flavor to cocktails and other foods, enhancing their flavor. When smoke enters a cocktail glass or other container, it comes into contact with the container and its contents (such as ice and liquid). The smoke's molecules (except for tar and carbon particles) dissolve in the moisture on the container's contents, transferring the smoke flavor and aroma to the drink or food. For example, the water film on the surface of ice cubes attracts and combines with the smoke, allowing the smoke to penetrate the cocktail and impart a smoky flavor. Traditional smokers consist of a glass dome or enclosed smoke box to contain smoke introduced from a handheld smoke generator. The smoke generator typically includes a chamber for receiving wood chips. The smoke generator is powered by an electric current, generating sufficient heat to fully combust the wood chips, producing smoke. The smoke is typically directed toward the food or drink using a tube, with a glass cover placed above the smoke and food / drink to allow the smoke to penetrate the food or drink. Another traditional smoker consists of a wooden board that can be placed next to the drink or food. A wooden board is lit with a lighter, and then a glass lid is placed over the burning portion of the board, with the edge of the lid facing downward. This allows the lid to collect smoke, which can be used to soak up beverages or food. However, these traditional smokers have many drawbacks. For example, they take up a large amount of space, which is undesirable, especially in a kitchen or bar. Furthermore, they require multiple moving parts, which can result in smoke loss. Furthermore, the smoke is only indirectly absorbed by the beverage or food, reducing its flavor and adding to its aroma. In light of these issues, various improved smokers have been proposed in the prior art.

[0004] For example, the invention patent application with publication number AU2021200576A1 discloses a smoker, which comprises a first port, a through hole and an insert to form a chamber for burning combustible materials, wherein the insert is located inside the through hole to accommodate and support the combustible material.

[0005] For example, Chinese utility model patent CN216688065U relates to a smoker for enhancing the flavor of beverages or food. The smoker comprises a body having an open first cavity and at least one smoke passage communicating with the first cavity. When the smoker body is placed over a container containing a beverage or food, the smoke passage communicates with the container's inner cavity.

[0006] For another example, Chinese utility model patent CN217826694U discloses a beverage smoker, which includes a smoker body and a smoker furnace. The smoker body is a hollow chamber structure, the smoker furnace is placed on top of the smoker body, and a smoker cavity is provided inside the smoker furnace, which is connected to the hollow chamber of the smoker body.

[0007] However, the aforementioned smokers all require a separate ignition device, such as a lighter gun, to ignite the combustible material to generate an open flame that burns for a period of time. This makes operation inconvenient. Furthermore, since a large amount of air enters through the top or bottom opening during the combustion of the combustible material in the existing smoker, maintaining the open flame, the entire process is very unsafe. Furthermore, the smoke utilization rate and smoking efficiency need to be further improved. Summary of the Invention

[0008] The object of the present invention is to provide a portable smoking machine, which can partially solve or alleviate the above-mentioned technical problems. It adopts a structural design that integrates an ignition device into one, and has a simple and portable structure. A tray is set in the combustion chamber of the lower mold, and a sealing cover is set to seal the accommodating cavity on the tray to form a sealed space. That is, by setting the sealed space, the amount of external air entering is limited, which is conducive to the incomplete combustion of the combustibles on the tray, that is, the process of generating smoke does not generate open flames, which ensures safety while generating more smoke than the open flame method. Further, by setting a specific smoke diffusion structure to cooperate with the air outlet channel on the tray, and using a smoke guiding component, the large amount of smoke generated in the relatively sealed tray can be spread over a larger area, so that the contact area between the smoke and the beverage or food is larger, which greatly improves the utilization rate of the smoke and even improves the efficiency of smoking.

[0009] In order to solve the above-mentioned technical problems, the present invention specifically adopts the following technical solutions:

[0010] The present invention provides a portable smoking machine, which comprises: a detachable upper mold and a lower mold, wherein:

[0014] When the upper mold and the lower mold are closed, the ignition component extends through the portion outside the sealing cover into the accommodating cavity, the sealing cover covers the top opening of the accommodating cavity, and the air pipe is connected to the accommodating cavity through the air outlet;

[0015] When sparks are provided to the combustible material in the accommodating cavity through the ignition component, causing the combustible material to burn incompletely and produce smoke, the air pump injects a guiding airflow into the accommodating cavity through the air pipe and the air outlet. The guiding airflow guides the smoke produced by the incomplete combustion of the combustible material to enter the base combustion chamber through the through hole in turn, and is diverted and diffused through the multiple diffusion holes of the smoke diffusion structure.

[0016] Preferably, the base combustion chamber includes a cavity for accommodating the tray, the bottom of the cavity protrudes from the lower surface of the lower mold to form a bowl-shaped or trumpet-shaped smoke diffusion structure, a plurality of diffusion holes are evenly spaced on an inclined side wall of the smoke diffusion structure, and the angle between the extension direction of the side wall and the central axis of the tray is 40°-60°;

[0017] When the smoker is placed on a container loaded with food to be smoked, the top edge of the container abuts against the lower surface of the lower mold, so that the smoke diffusion structure extends into the container and is located above the food.

[0018] Preferably, the angle between the central axis of the diffusion hole on the side wall and the side wall is 90°-120°.

[0019] Preferably, an inflation cavity connected to the air pipe is provided in the sealing cover, and the air outlet is provided on the bottom wall of the inflation cavity.

[0027] Preferably, a heat insulating member is provided between the sealing cover and the upper mold bottom plate of the upper mold.

[0028] Preferably, a uniform aperture is provided on the top of the upper mold.

[0029] Preferably, an anti-slip part is provided on the lower surface of the lower mold.

[0030] Beneficial effects of the present invention: All existing smokers require a separate ignition device for ignition, and they all use an open flame for full combustion or full combustion most of the time. On the one hand, people may forget to bring their ignition device, and on the other hand, open flame combustion not only easily causes safety problems, but also for some special scenarios, such as bars and cafes, open flames are actually undesirable, which makes this type of smoker no longer applicable. In addition, compared to larger foods that require a large amount of smoke and take a long time to smoke, some small foods such as desserts or beverages require less smoke and take a short time to smoke, although their smoke requirements are smaller, in order to smoke efficiently while ensuring the richness of the smoked food, the smoke volume cannot be too small. Therefore, in the present application, a smaller accommodating chamber is set in the combustion chamber, and its top opening is sealed by a sealing cover, while the through hole at the bottom is blocked by the combustible material, so that the accommodating chamber forms a relatively closed and sealed space, and then a high-voltage coil is used to generate an arc to pyrolyze the wood chips to produce smoke. During the smoke generation process, since the through hole at the bottom of the closed space is blocked by the combustible material, and there is only one air inlet at the top (that is, the air outlet of the inflation chamber), that is, the amount of external air entering the accommodating chamber is limited by setting the closed space, so that the combustible material is not fully burned in the accommodating chamber, and then a small amount of combustible material is not fully burned in the closed space, thereby generating more smoke (compared with full combustion, the amount of smoke generated by incomplete combustion is larger), and the smoke flow is guided, diverted and diffused by the smoke guiding component and the smoke diffusion structure, so that the smoke can fully contact the food.

[0031] (1) The present invention provides a detachably connected upper mold and a lower mold, the upper mold is provided with an ignition device and a smoke guiding assembly for guiding the movement of smoke, the lower mold is provided with a base combustion chamber, the ignition component of the ignition device in the upper mold extends into the base combustion chamber, such a structural design ensures the integrated structure of the ignition device and the smoker; in addition, a tray is provided in the base combustion chamber, the tray is a receiving cavity with an open top, in which combustibles are placed, a plurality of through holes are provided on the bottom wall of the receiving cavity, a diffusion hole is provided in the lower part of the base combustion chamber, and the through hole is connected to the outside through the diffusion hole, and a sealing cover is also provided on the upper mold, and when the upper mold and the lower mold are closed, the sealing cover covers the tray, thereby ensuring the sealing of the tray and not damaging the bottom of the upper mold in contact with the tray; by providing a tray for burning combustibles on the base combustion chamber, the receiving cavity of the tray is small and is in contact with the outside air only through the through hole, and the through hole is blocked by the combustibles during the combustion process, thereby limiting the outside air from entering the container. The amount of the receiving cavity is conducive to the incomplete combustion of the combustible material, and can produce a large amount of smoke in a limited space. At the same time, the double-layer structure of the base combustion chamber and the tray, while ensuring the combustion of the combustible material, provides a guiding diffusion hole for the flow path of the smoke, that is, the airflow in the trachea is connected to the receiving cavity of the tray through the gap between the sealing cover and the ignition component. When the combustible material is ignited, the contact area between the receiving cavity in the tray and the outside world is not large, the combustible material is not fully burned in the tray, and more smoke is generated. Under the action of the airflow in the trachea, the smoke quickly flows from the through hole in the tray to the diffusion hole in the base combustion chamber, and the diffusion hole is aimed at the food to be smoked. Such a structural setting sets a path for the circulation of smoke, and in such a path, the smoke is quickly generated in large quantities in the tray and flows to the food or beverage through the diffusion hole. The smoke spreads over a larger area, and the contact area with the food or beverage that needs to be contacted is even larger, so the utilization rate of the smoke and the smoking efficiency are higher.

[0032] (2) The present invention provides a plurality of diffusion holes evenly spaced on the side wall of the smoke diffusion structure of the bottom combustion chamber. Since the side wall is inclined, the angle between it and the central axis of the tray is 40°-60°, or the angle between it and the bottom wall is 130°-150°, so that the smoke flowing out of the through hole at the bottom of the tray is diverted and diffused through the diffusion holes dispersed around it, so that the spreading area of ​​the smoke is larger.

[0033] (3) The present invention provides a first magnetic part and a second magnetic part so that the upper mold and the lower mold can be easily disassembled, and a sensor is provided on the upper part of the upper mold near the first magnetic part. After the upper mold and the lower mold are correctly installed, the second magnetic part approaches the sensor, and the sensor sends an electrical signal. This method ensures that the installation positions of the two are correct. BRIEF DESCRIPTION OF THE DRAWINGS

DETAILED DESCRIPTION

[0044] To make the purpose, technical solutions, and advantages of the embodiments of the present invention more clear, the technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0045] As used herein, terms such as "upper," "lower," "inner," "outer," "front," "back," "one end," and "the other end" indicate positions or locations based on those shown in the accompanying drawings. These terms are intended solely to facilitate and simplify the description of the present invention and are not intended to indicate or imply that the devices or components referred to must have, be constructed, or operate in a specific orientation. Therefore, they should not be construed as limitations on the present invention. Furthermore, the terms "first" and "second" are used for descriptive purposes only and should not be construed as indicating or implying relative importance.

[0046] To achieve compact portability, the present invention provides a portable smoker comprising a tray for holding a small amount of combustible material. The tray has only a through-hole at the bottom and a sealed top, forming a relatively sealed chamber. During combustion, sufficient air within the chamber allows the combustible material to ignite. However, the lack of additional air during combustion results in incomplete combustion, resulting in a large amount of smoke (compared to open flame combustion). Furthermore, by drawing air from the outside and providing a guided airflow into the chamber, the resulting smoke flows out in a designated direction and is then dispersed and diffused through a smoke diffusion structure at the bottom of the tray. This method, first "gathering" the smoke by the tray and then "amplifying and diffusing" it by the smoke diffusion structure, ensures that the combustible material in the chamber can be ignited and partially burned while also preventing the smoke generated by incomplete combustion from flowing elsewhere and causing waste. This improves the effective utilization of the combustible material and increases the smoke's spread area, allowing it to be better absorbed by food. This will be described below with reference to specific embodiments.

[0047] like Figure 1a-Figure 7 As shown, the portable smoker of the present invention includes: a detachable upper mold 2 and a lower mold 24, wherein the upper mold 2 is provided with an ignition device for providing sparks, and a smoke guide assembly for providing a guide airflow to guide the direction of smoke movement; wherein the lower mold 24 is provided with a base combustion chamber 21, wherein the base combustion chamber 21 is provided with a tray 19 for carrying combustibles, and a smoke diffusion structure 29 is provided below the tray 19 for diverting and diffusing smoke generated by incomplete combustion of the combustibles.

[0048] In some embodiments, the smoke guide assembly includes an air pump 11 and an air pipe 8 connected to the air pump 11. The air pump 11 draws air from the outside (preferably, the air pump 11 draws air from the interior space of the upper mold 2; more preferably, the upper mold 2 is provided with air holes connected to the outside) and applies a unidirectional guided airflow into the tray 19 through the air pipe 8. The unidirectional guided airflow ensures that the generated smoke moves in the direction of the guided airflow under the action of the guided airflow, thereby preventing the smoke from entering other locations. For example, the smoke does not gather on the top of the tray 19 and enter the upper mold 2. Specifically, the ignition device and the smoke guide assembly are disposed on the upper mold base plate 13 within the upper mold 2, that is, the upper mold base plate 13 separates the upper mold 2 and the lower mold 24.

[0049] Preferably, the ignition device includes a high-voltage package 10 and an ignition component, wherein the ignition component adopts a ceramic head 14, the high-voltage package 10 is arranged on the upper mold base plate 13, the high-voltage package 10 is connected to the ceramic head 14, and the high-voltage discharge of the high-voltage package 10 causes the ceramic head 14 to generate electric sparks, and the combustible material is ignited under the action of the electric sparks.

[0050] See also Figure 3 In this embodiment, the tray 19 is removably mounted within the base combustion chamber 21 (for example, by being placed on top of the base combustion chamber 21 via the lugs on the top of the tray 19). The tray 19 includes a receiving cavity 190 with an open top. A plurality of through-holes 27 are provided on the bottom wall of the receiving cavity 190, allowing the receiving cavity 190 within the tray 19 to communicate with the base combustion chamber 21 and connect to the outside world via the plurality of diffusion holes 26 in the smoke diffusion structure 29 at the bottom of the base combustion chamber 21. Preferably, the tray 19 is in the shape of a truncated cone, with a larger top and a smaller bottom, and a lug extending from the top. Accordingly, a plurality of through-holes 27 are evenly distributed within the bottom disc. Figure 7 .

[0051] In this embodiment, the tray 19 and the base combustion chamber 21 form a double-layer structure. On the one hand, the tray 19's accommodating cavity 190 is relatively small and sealed at the top by the sealing cover 16. It communicates with the outside world only through the through-hole 27 at the bottom and the diffusion holes 26 in the bottom smoke diffusion structure 29. This ensures that when the combustible material is ignited, the oxygen content within the tray 19 is sufficient to ignite the combustible material. At the same time, because the through-hole 27 communicating with the base combustion chamber 21 is blocked by the combustible material, the ingress of outside air through the through-hole 27 is minimal. Therefore, when the combustible material burns, the oxygen content within the sealed (not absolutely sealed, but merely limited) tray 19 does not increase significantly. Consequently, the combustible material does not fully burn or fully burns quickly, resulting in more smoke than would be produced if fully burned. In other words, even a small amount of combustible material can produce considerable smoke, significantly improving the utilization rate of the combustible material. Furthermore, when the combustible material burns, an air insulation cavity is formed between the tray 19 and the base combustion chamber 21, providing thermal insulation and protection for the lower mold 24. Of course, in other embodiments, the combustible material itself is also relatively special and is not easy to fully burn. Specifically, the combustible material is a spice commonly used in smoking food.

[0052] See also Figure 2 In this embodiment, a sealing cover 16 is provided on the upper mold 2. The sealing cover 16 is made of heat-resistant material, such as stainless steel. Preferably, the sealing cover 16 is embedded or snapped onto the upper mold base plate 13, and a heat insulation pad 18 is provided between the sealing cover 16 and the upper mold base plate 13. Figure 2 In this embodiment, a PVC protective cotton strip 12 is also provided on the upper mold bottom plate 13.

[0053] See also Figure 3 An air-filling cavity 160 is provided in the sealing cover 16, and the air pipe 8 is connected to the air-filling cavity 160. The ceramic head 14 passes through the top wall and the bottom wall of the air-filling cavity 160 in sequence and extends to the outside of the air-filling cavity 160. When the upper mold 2 and the lower mold 24 are installed together, one end of the ceramic head 14 extends out of the air-filling cavity 160 and extends into the tray 19.

[0054] Specifically, a gas outlet is provided on the bottom wall of the plenum chamber 160, and the ceramic head 14 extends out of the plenum chamber 160 from the gas outlet. The gas outlet is larger than the ceramic head 14, leaving a certain gap between them. In other words, a certain gap is left between the sealing cover 16 and the ceramic head 14, which connects the plenum chamber 160 with the accommodating chamber 190. Due to the provision of the plenum chamber 160, a heat-insulating space formed by air is formed on the top of the tray 19 during the combustion process, that is, the plenum chamber 160 also becomes a heat-insulating chamber.

[0055] In other embodiments, the sealing cover 16 may also be made directly of a stainless steel plate, and the edges thereof are upturned. When the edges thereof are embedded in the upper mold base plate 13, an air-filled cavity is formed between the sealing cover 16 and the upper mold base plate 13; or, a groove is directly provided on the upper mold base plate 13. When the sealing cover 16 is detachably mounted on the upper mold base plate 13 to cover the groove, the air-filled cavity is formed between the groove and the sealing cover 16.

[0056] In some embodiments, a sealing ring 17 is provided between the tray 19 and the base combustion chamber 21 .

[0057] When the device is in operation, since the air pump 11 is arranged in the upper mold 2, and its inlet only draws air from the upper mold 2, and due to the arrangement of the upper mold bottom plate 13 and the sealing cover 16, when the air pump 11 only draws air from the upper mold 2, it will not inhale the smoke generated in the accommodating cavity 190, but will guide the airflow inhaled from the upper mold 2 into the inflation cavity 160 through the air pipe 8, and then downward from the air outlet on the bottom wall of the inflation cavity 160, that is, the gap between the sealing cover 16 and the ceramic head 14 into the accommodating cavity 190 on the tray 19, and, under the action of the air flow pressure, the smoke generated by incomplete combustion only enters the buffer area between the bottom of the tray 19 and the bottom wall of the smoke diffusion structure 29 from the bottom wall through hole 27 of the tray 19, and finally passes through the diffusion hole 26 at the bottom of the smoke diffusion structure 29 for diversion and diffusion.

[0058] Preferably, the central axis of the air outlet of the inflation chamber 160 coincides with the central axis of the tray 19, so that the air outlet corresponds to the through hole 27 at the bottom of the tray 19, ensuring that the airflow flowing out from around the ceramic head 14 can cover the through hole 27 at the bottom of the tray 19, thereby directionally draining the smoke and avoiding a large amount of smoke accumulation at the top of the tray 19.

[0059] See also Figure 3 、 Figure 5 and Figure 6 In this embodiment, the base combustion chamber 21 includes a cavity for accommodating the tray 19, and the bottom of the cavity protrudes from the lower surface of the lower mold 24 to form a bowl-shaped, trumpet-shaped, or conical frustum-shaped smoke diffusion structure 29, and the smoke diffusion structure 29 has a plurality of diffusion holes 26 evenly spaced on the inclined side walls.

[0060] Preferably, the angle α between the side wall and the central axis of the tray 19 or the central axis of the base combustion chamber 21 is 40°-60°, or the obtuse angle between the side wall and the horizontal plane is 130°-150°.

[0061] In some embodiments, the tray 19 is a bowl-shaped structure, and the tray 19 is located at the upper part of the base combustion chamber 21 (that is, above the smoke diffusion structure 29), and the space between the bottom of the tray 19 and the bottom of the base combustion chamber 21 forms a buffer area for buffering and diversion, so that the smoke flowing out through the through hole 27 is diverted and diffused through the diffusion hole 26. Compared with setting a large through hole set along the central axis, the spreading area of ​​the smoke is greatly increased, thereby making the smoking efficiency higher, or after the same smoking time, the taste of the food is more uniform and richer.

[0062] Furthermore, to accommodate containers of varying cross-sectional sizes, the central axis of the diffusion hole 26 may be perpendicular to the obliquely arranged sidewall of the smoke diffusion structure 29, or the obtuse angle β1 / β2 between the central axis of the diffusion hole 26 and the sidewall may be a maximum of 120°. If the angle β1 is too large, the smoke spreads over a large area, causing the smoke volume in the area below the smoke diffusion structure 29 to be uneven compared to other areas, resulting in an uneven smoked flavor. If the angle β2 is too small, the smoke spreads over a small area, requiring a considerable amount of time for the smoke to disperse evenly, resulting in low efficiency and, in particular, inconvenient for table turnover in scenarios requiring short, frequent smoking.

[0063] In some embodiments, the smoker further includes a main control board 5, which is mounted on the upper mold base plate 13 via screws 4. The main control board 5 is electrically connected to the high-voltage package 10 of the ignition device and the air pump 11 in the smoke guide assembly. The main control board 5 controls the operation of the ignition device and the air pump 11. The smoker can be operated by pressing a related button (such as the on / off button).

[0064] In some embodiments, a battery 9 is further provided in the upper mold 2 and is disposed on one side of the air pump 11. The battery 9 is connected to the main control board 5, the ignition device, and the air pump 11 to provide power for the operation of the device. Furthermore, a power supply port is provided on the upper mold 2.

[0065] In some embodiments, a uniform aperture 1 is provided on the top of the upper mold 2 .

[0066] When the smoker of this embodiment is placed on a container containing food to be smoked, the top edge of the container abuts against the lower surface of the lower mold 24, allowing the smoke diffusion structure 29 to extend into the container and above the food. This not only shortens the distance between the smoker and the food, but also, when the smoker is not in use and placed on a table, only the smoke diffusion structure 29 comes into direct contact with the table, while the lower surface of the lower mold 24 does not. This prevents contamination of the container or even the food within from the contaminated lower surface. Furthermore, the lower surface of the lower mold 24 is provided with anti-slip features 25, such as anti-slip grooves or a non-slip pad, to ensure the stability of the smoker's position on the container during the smoking process.

[0067] like Figure 4 and Figure 5 As shown, a first magnetic member 22 (e.g., a magnet) is provided at the bottom edge of the upper mold 2, and a second magnetic member 23 (e.g., a magnet) is provided at the upper edge of the corresponding lower mold 24, which can be adsorbed with the first magnetic member 22, so that the upper mold 2 and the lower mold 24 are stably adsorbed together through the two magnetic members.

[0068] Furthermore, a sensor 7 (such as a Hall sensor) electrically connected to the main control board 5 is installed in the upper mold 2, and a third magnetic part, such as a magnet 30, is provided on the lower mold 24 at a position corresponding to the sensor 7 (preferably, the Hall sensor has a built-in magnet corresponding to the third magnetic part). When the lower mold 24 and the upper mold 2 are correctly installed, the magnet 30 of the lower mold 24 is close to the sensor 7, and the sensor 7 generates an electrical signal, which can then detect whether the installation position is correct.

[0069] In this embodiment, the combustible material includes sawdust, which can be made from different woods, such as oak, applewood, etc. Sawdust from different woods has different aromas, and users can choose according to their taste. The working principle of the smoker of this embodiment is described in detail below using sawdust as an example.

[0070] During the specific implementation, apple wood chips are placed on the tray 19, and then the tray 19 is installed in the combustion chamber of the lower mold 24, and then the upper mold 2 and the lower mold 24 are covered so that the sealing cover 16 on the upper mold 2 seals the accommodating cavity 190 on the tray 19, thereby forming a relatively sealed accommodating cavity 190, and then the switch button is clicked, the high-voltage package 10 (i.e., the arc emitter) and the air pump 11 work at the same time, and each time they are turned on, the total working time of the high-voltage package 10 (i.e., the arc emitter) and the air pump 11 is 14s, among which the air pump 11 works all the time (i.e., the working time of the air pump 11 is 14s), and the high-voltage package 10 is in intermittent working mode, that is, it works for 6s, and then works for 6s after a gap of 2s.

[0071] During the actual comparative test, when the upper mold 2 was not installed, the apple sawdust on the tray 19 in the combustion chamber of the lower mold 24 could be ignited by a lighter and burned with an open flame. However, after the same apple sawdust was loaded into the tray 19 and the upper mold 2 was installed, the apple sawdust blocked the through hole 27 at the bottom of the tray 19, and the opening at the top of the tray 19 was blocked by the sealing cover 16. Therefore, once the ignition device and the air pump 11 were turned on, the apple sawdust was not fully burned in the tray 19. That is, by setting up the sealed space to limit the entry of outside air, the amount of air entering the sealed space can only be controlled by controlling the air pump 11, so that the sealed space forms a low-oxygen environment, thereby achieving incomplete combustion. In other words, compared with the open combustion in the prior art, which allows a large amount of oxygen to be obtained from the outside for sufficient combustion during the combustion process, the sealed space in this embodiment is provided to help achieve or promote incomplete combustion of combustibles in the sealed space.

[0072] In addition, since no additional large amount of air (i.e., oxygen) enters the sealed space, and the airflow ejected from the air outlet of the inflation chamber 160 surrounds the ceramic head 14, it can quickly take away the residence time of the smoke generated by incomplete combustion in the high-temperature area. On the other hand, the high-temperature area formed by the high-pressure package 10 and the ceramic head 14 consumes oxygen too quickly, and the airflow ejected from the air outlet in a short period of time cannot evenly penetrate into the wood chips, thereby forming a local oxygen-deficient area, which promotes incomplete combustion.

[0073] The embodiments of the present invention are described above in conjunction with the accompanying drawings, but the present invention is not limited to the above-mentioned specific implementation methods. The above-mentioned specific implementation methods are merely illustrative and not restrictive. Under the guidance of the present invention, ordinary technicians in this field can also make many forms without departing from the scope of protection of the present invention and the claims, all of which are protected by the present invention.
