[0043] See also Figure 1 and Figure 2 This embodiment relates to an automatic smoker, which is mainly used to burn or partially burn a combustion medium (such as wood chips) to generate smoke. The automatic smoker includes: a main unit 1, a pipe 2 and a base 3.

[0044] Specifically, the main unit 1 and base 3 are cylindrical in shape. A pipe 2 is positioned between the two, containing a combustion chamber 20 where the combustion medium burns or partially burns. The main unit 1 and base 3 are detachably assembled, and the assembly of the two units securely compresses the pipe 2. Furthermore, the assembly of the main unit 1 and base 3 seals the combustion chamber 20, preventing it from being exposed. This reduces the risk of combustion and enhances the safety of the automatic smoker.

[0045] See also Figure 3 In this embodiment, a smoke outlet 21 is provided on the pipe 2, and the smoke outlet 21 is connected to the combustion chamber 20. The smoke outlet 21 can quickly discharge the smoke generated by combustion or incomplete combustion in the combustion chamber 20, so that the automatic smoker can quickly emit smoke.

[0046] See also Figure 4 and Figure 5 In one embodiment, the host 1 includes: a shell 11, a bottom cover 12 and a heat-insulating cover 13. The shell 11 is cylindrical as a whole and has a mounting cavity 110. The bottom cover 12 is connected to the side of the shell 11 close to the base 2, thereby closing the opening of the mounting cavity 110. An air inlet 120 is provided on the end surface of the bottom cover 12 close to the base 2, which passes through the bottom cover 12. The heat-insulating cover 13 is provided on the side of the bottom cover 12 away from the shell 11 and is connected to the bottom cover 12. A gap 10 is provided between the heat-insulating cover 13 and the bottom cover 12 for the gas entering the air inlet 120 to pass through. An air inlet 130 is provided on the heat-insulating cover 13, and the air inlet 130 is staggered with the air inlet 120.

[0047] See also Figures 6 to 9 It should be noted that when the main unit 1 and base 3 are assembled, the heat-insulating cover 13 abuts against the end surface of the pipe 2 near the main unit 1, sealing the combustion chamber 20 and ensuring the safety of the combustion process. Simultaneously, the air inlet 130 communicates with the combustion chamber 20, providing combustion-supporting gas to the combustion chamber 20 and ensuring the smooth progress of the combustion process. Combustion-supporting gas includes, but is not limited to, oxygen and air.

[0048] It should also be noted that Figure 9The dashed arrows in the middle indicate the direction of airflow. When the combustion medium burns or burns insufficiently in the combustion chamber 20, since the insulation cover 13 needs to be in contact with the pipe 2, the heat generated by the combustion or insufficient combustion of the combustion medium will cause the insulation cover 13 to heat up rapidly, and a gap 10 is set between the insulation cover 13 and the bottom cover 12, which can form an insulation belt for isolating heat between the end surface of the insulation cover 13 in contact with the pipe 2 and the gas between the bottom cover 12, thereby preventing the heat of the insulation cover 13 from being directly transferred to the bottom cover 12; in addition, the air inlet 120 and the air inlet 130 are both connected to the gap 10, that is, the air inlet 120 is connected to the air inlet 130 through the gap 10, and the combustion-supporting gas is sent into the combustion chamber 20, and the air inlet 120 and the air inlet 130 are staggered, which has a blocking effect on the combustion-supporting gas entering the gap 10, so that the gas in the gap 10 can absorb part of the heat on the insulation cover 13, and at the same time, the heat absorbed by the combustion-supporting gas is discharged from the combustion chamber 20 along with the smoke, thereby achieving the effect of cooling the insulation cover 13. The automatic smoker configured in this way can not only prevent the heat generated by combustion or incomplete combustion from being transferred to the main unit 1 during operation, but also can cool the heat insulation cover 13, thereby improving the working environment of the main unit 1 and increasing the service life of the main unit 1.

[0049] See also Figure 5 In one embodiment, a first connecting portion 121 is provided on the side of the bottom cover 12 near the heat insulating cover 13. A second connecting portion 131 is provided on the side of the heat insulating cover 13 near the bottom cover 12. The first connecting portion 121 and the second connecting portion 131 are detachably assembled to facilitate replacement of the heat insulating cover 13 by the user.

[0050] See also Figure 2 、 Figure 5 、 Figure 10 and Figure 12 In one embodiment, the first connection portion 121 is a plug hole 1210, and a hook portion 1211 is provided in the plug hole 1210. The first end of the hook portion 1211 is flush with the end surface of the bottom cover 12 on the side close to the base 3, and the second end of the hook portion 1211 is lower than the opening of the plug hole 1210 on the side away from the base 3. The end surface of the second end of the hook portion 1211 and the inner wall of the bottom cover 12 form a groove 1212 for accommodating a portion of the second connection portion 131.

[0051] The second connecting portion 131 includes a connecting section 1311 and a bent section 1312. A first end 1311a of the connecting section 1311 is connected to the thermal insulation cover 13. A second end 1311b of the connecting section 1311 is connected to the bent section 1312. The bent section 1312 is received in the recess 1212, hooking onto the hook portion 1211 to secure the thermal insulation cover 13.

[0052] In one embodiment, the width of the connecting section 1311 is smaller than the width of the bending section 1312, so that the connection between the connecting section 1311 and the bending section 1312 forms a stepped structure to facilitate bending of the bending section 1312. The angle between the bending section 1312 and the connecting section 1311 is an acute angle or a right angle, so that the bending section 1312 cooperates with the hook portion 1211.

[0053] It should be noted that the second connecting portion 131 can both maintain the connection between the connecting section 1311 and the bent section 1312 under the action of an external force and return to its original shape under the action of an external force. Before the second connecting portion 131 is assembled with the first connecting portion 121, the connecting section 1311 and the bent section 1312 are integral and coplanar. When assembling the thermal insulation cover 13 and the bottom cover 12, the bent section 1312 is inserted into the insertion hole 1210, so that the connecting section 1311 is completely accommodated within the insertion hole 1210, and the bent section 1312 is extended out of the insertion hole 1210. Then, an external force is applied to the bent section 1312, causing it to bend and be accommodated within the groove 1212, thereby completing the assembly of the thermal insulation cover 13 and the bottom cover 12. When removing the thermal insulation cover 13, the bent section 1312 can be simply restored to its original shape by applying an external force until it is coplanar with the connecting section 1311.

[0054] Please continue reading Figure 2 、 Figure 5 、 Figure 10 and Figure 11 In one embodiment, the heat-insulating cover 13 includes a cover body 132 and a flange 133. The cover body 132 is configured to fit over the pipe 2 to seal the combustion chamber 20. The flange 133 has a fixed end 1331 and a free end 1332. The fixed end 1331 is connected to the cover body 132, while the free end 1332 extends toward one side of the bottom cover 12. The free end 1332 of the flange 133 is configured to abut against the end surface of the bottom cover 12 near the base 3, thereby forming a gap 10 between the bottom cover 12 and the cover body 132.

[0055] In one embodiment, a mounting groove 122 is provided on the bottom cover 12 near the base 3. The air inlet 120 is connected to the mounting groove 122, and the plug hole 1210 is provided in the mounting groove 122. The heat insulating cover 13 is installed in the mounting groove 122, and the free end of the protrusion 133 abuts against the inner wall of the mounting groove 122.

[0056] In one embodiment, the notch of the mounting slot 122 is provided with an angled angle 1221. This configuration effectively prevents the pipe 2 from directly contacting the bottom cover 12 when the main unit 1 is assembled with the base 3, thereby preventing heat from the pipe 2 from being directly transferred to the bottom cover 12, further improving the heat insulation effect of the main unit 1.

[0057] In this embodiment, the mounting groove 122 is a groove with a circular cross-section, and the heat-insulating cover 13 is generally circular and adapted to the mounting groove 122. The flange 133 is an annular wall connected to the edge of the cover body 132. Three first connecting parts 121 are provided, and the three first connecting parts 121 are distributed in a circular shape at equal intervals at the bottom of the mounting groove 122. Three second connecting parts 131 are also provided, and the three second connecting parts 131 are distributed in a circular shape at equal intervals at the free end of the flange 133, and are all connected to the free end. The cover body 132, the flange 133, and the second connecting part 131 are integrally formed. The heat-insulating cover 13 is made of stainless steel, so that the second connecting part 131 can be bent or restored to its original shape multiple times.

[0058] In one embodiment, an annular protrusion 1222 is provided on the bottom wall of the mounting groove 122. The annular protrusion 1222 and the side wall of the mounting groove 122 form an annular groove, and the ridge 133 is assembled in the annular groove, so that the annular protrusion 1222 blocks the ridge 133, thereby improving the airtightness between the thermal insulation cover 13 and the bottom cover 12. At the same time, the formation of the annular groove can limit the ridge 133, improving the secure assembly between the bottom cover 12 and the thermal insulation cover 13.

[0059] See also Figure 4 、 Figure 5 and Figure 16 In one embodiment, the host 1 further includes: a blower 14, a circuit board 15 and a power supply 16.

[0092] Compared with the prior art, the beneficial effects of the present invention are as follows:

[0093] 1) A gap 10 is provided between the heat-insulating cover 13 and the bottom cover 12 so that the gas between the end surface of the heat-insulating cover 13 in contact with the pipe 2 and the bottom cover 12 forms an insulating zone that isolates heat, thereby preventing the heat of the heat-insulating cover 13 from being directly transferred to the bottom cover 12.

[0094] 2) Air inlet 120 communicates with air inlet 130 through gap 10, delivering combustion-supporting gas into combustion chamber 20. Air inlet 120 and air inlet 130 are offset, creating a barrier to combustion-supporting gas entering gap 10, allowing the gas within gap 10 to absorb some of the heat from thermal cover 13. Simultaneously, the heat absorbed by the combustion-supporting gas is discharged from combustion chamber 20 along with the smoke, thereby cooling thermal cover 13. This arrangement of the automatic fumigator not only prevents heat generated by combustion or incomplete combustion from being transferred to main unit 1 during operation, but also cools thermal cover 13, improving the operating environment of main unit 1 and extending its service life.

[0095] 3) The notch of the mounting slot 122 is provided with an angled corner 1221. This arrangement effectively prevents direct contact between the pipe 2 and the bottom cover 12 when the main unit 1 is assembled with the base 3, thereby preventing heat from the pipe 2 from being directly transferred to the bottom cover 12, further improving the heat insulation effect of the main unit 1.

[0096] The above description is merely a preferred embodiment of the present invention and is not intended to limit the present invention. Those skilled in the art will readily appreciate that the present invention is susceptible to various modifications and variations. Any modifications, equivalent substitutions, or improvements made within the spirit and principles of the present invention shall be included within the scope of protection of the present invention.
