[0032] Example 1

[0033] A smoke generator for producing smoke to smoke food, clothing or other items.

[0034] like Figure 1-5 As shown, the smoke cooler includes a housing 10, a pipe 20, and a base 31. A chamber 101 is provided inside the housing 10, where smoke fuel is ignited and burned to produce smoke. The pipe 20 passes through the housing 10 for inputting gas into the chamber 101 and outputting the smoke produced by combustion for smoking.

[0035] The shell 10 is cylindrical in shape, and its internal cavity is formed as chamber 101. In other embodiments, the shell 10 may also be other shapes, such as cubic, spherical, etc., and is not limited thereto.

[0036] Preferably, the housing 10 has an opening 102 at its top, and a cover 103 is provided over the opening 102. The cover 103 is provided to facilitate the addition of fuel to the chamber 101 or to observe the internal combustion. In other embodiments, the cover 103 may also be provided on the side wall of the housing 10.

[0037] In addition, a vent 104 is provided at the lower end of the side wall of the housing 10, and a vent cover 105 is movably disposed at the vent 104. By adjusting the closed state of the vent cover 105, the air intake can be increased or decreased to adjust the degree of combustion. Preferably, a vent hole is provided on the vent cover 105 to set the minimum air intake of the vent cover 105 and to ensure that the vent 104 is not completely blocked.

[0038] The pipe fitting 20 is preferably arranged in a straight line, passing through the lower end of the housing 10 into the chamber 101 and exiting from the other side. One end of the pipe fitting 20 is formed as the air supply end 201, and the other end is formed as the smoke outlet end 202. The portion of the pipe fitting 20 inside the chamber 101 is provided with an air inlet 203 that communicates with the chamber 101. The pipe inside the pipe fitting 20 is connected to the chamber through the air inlet 203, so that the smoke generated in the chamber 101 can be drawn out by the air source provided by the air supply end 201 and discharged from the smoke outlet end 202.

[0039] The pipe fitting 20 has a notch 224 on its lower side, which is set downward to avoid fuel or ash from accumulating in the pipe fitting 20 and reduce the possibility of fuel or ash being discharged from the smoke outlet 202. The notch 224 forms the air vent 203.

[0040] Preferably, the pipe fitting 20 includes a first pipe fitting 21 and a second pipe fitting 22. The side wall of the housing 10 is provided with a first pipe hole 106 and a second pipe hole 107. The rear end of the first pipe fitting 21 extends from the left side into the first pipe hole 106 and into the chamber 101. The front end of the second pipe fitting 22 extends from the right side into the second pipe hole 107 and into the chamber 101. The first pipe fitting 21 is fitted inside the second pipe fitting 22, with the outer diameter of the first pipe fitting 21 being smaller than the inner diameter of the second pipe fitting 22 to form a gap between them. A notch 224 is provided on the side wall of the second pipe fitting 22. An air supply end 201 is formed at the front end of the first pipe fitting 21, and a smoke outlet end 202 is formed at the rear end of the second pipe fitting 22. In other embodiments, the air inlet 203 may also be formed by a through hole provided on the side wall of the second pipe fitting 22. In this context, "front end," "back end," "left side," and "right side" are understood as shown in Figures 1-5 (the left side in the diagram represents the front end / left side, and the right side represents the back end / right side); additionally, refer to... Figure 3-5 As shown, the second pipe fitting 22 was originally a hollow pipe. A notch 224 was formed by cutting the lower left side wall of the pipe fitting 224. The original side wall of the second pipe fitting 22 between the two notches 224 was formed into a fastener 223.

[0041] When airflow is input from the air supply end 201, the airflow is ejected from the rear end of the first pipe fitting 21. Since the first pipe fitting 21 is sleeved inside the second pipe fitting 22, a negative pressure is generated inside the second pipe fitting 22 to draw the smoke in the chamber 101 into the second pipe fitting 22 from the air inlet 203 and discharge it from the smoke outlet 202 at the rear end of the second pipe fitting 22.

[0042] In this embodiment, the pipe fitting 20 is installed by using two pipe fittings of different diameters, so that the first pipe fitting 21 has a smaller inner diameter, which allows the gas to have a higher flow rate and is conducive to the intake of smoke at the air inlet 203, while the second pipe fitting 22 has a larger inner diameter, which is conducive to providing a larger flow rate of fumigation mixture.

[0043] As a preferred option, such as Figure 5 As shown, the first pipe fitting 21 consists of an outer pipe fitting 211 and an inner pipe fitting 212. The inner pipe fitting 212 has a connecting end 213 at its front end, and the outer wall of the connecting end 213 is threaded. The front end of the outer pipe fitting 211 forms an air supply end 201, and the rear end has an internal thread, allowing the connecting end 213 of the inner pipe fitting 212 to be threadedly connected to the rear end of the outer pipe fitting 211. Simultaneously, the front end of the second pipe fitting 22 has a sleeve 221, and the sleeve 221 has an inner sleeve hole 22. 2. The inner wall of the socket 222 is provided with an internal thread, so that the socket 222 and the connecting end 213 of the inner tube 212 are also threadedly connected. That is, the external thread on the outer wall of the connecting end 213 is used to connect with the rear end of the outer tube 211 and the socket 221, so that the rear end of the outer tube 211 and the front end of the second tube 22 can respectively abut against the side wall of the shell 10 on both sides of the shell side wall at the first tube hole 106, thereby positioning and assembling the tube 20 on the shell 10.

[0044] In this embodiment, an opening 108 is formed at the bottom end of the housing 10, and the base 31 is detachably mounted at the opening 108 so that the base 31 can be removed when needed, for example, to repair the pipe 20 or to clean the housing 10. A fixing member 223 is provided on the original side wall of the second pipe 22, and the fixing member 223 is located at the center of the housing 10. Notches 224 are provided on the left and right sides of the fixing member 223 to serve as air inlets 203. Preferably, the fixing member 223 is formed by the original side wall of the second pipe 22.

[0045] In order to fasten the base 31 to the fixing member 223 by the screw fastener 32, the fixing member 223 is provided with a fastening hole 234, which can be a through hole or a threaded hole, for the screw fastener 32 to be threaded into the fastening hole 234. When a through hole is used, the threaded connection can be formed by the self-tapping of the screw fastener 32.

[0046] In this embodiment, the screw fastener 32 is also provided with an abutting nut 235. The abutting nut 235 is threadedly connected to the screw fastener 32 and abuts against the fixing member 223 after the screw fastener 32 is threadedly connected to the fastening hole 234, so as to prevent the screw fastener 32 from loosening from the fastening hole 234, thereby achieving convenient assembly and stable connection.

[0047] A through hole 301 is provided on the base 31. After the screw fastener 32 passes through the through hole 301, it is fastened at the lower end of the base 31 via the second fastening member 322, that is, the base 31 is detachably connected by the second fastening member 322. Preferably, the second fastening member 322 is made of a wing nut (or can be replaced by a regular nut), which is convenient to tighten manually without the aid of tools.

[0048] In this embodiment, the screw fastener 32 and the fixing member 223 are detachably connected, and the base 31 and the screw fastener 32 are detachably connected, so they can be disassembled at either point. In other embodiments, the screw fastener 32 and the fixing member 223 can also be fixedly connected, or the screw fastener 32 and the second clamping member 322 can be fixedly connected or integrally formed; for example, eye bolts or ordinary bolts can be used to replace the screw fastener 32 and the second clamping member 322. Compared with the above replacement methods, this embodiment provides multiple detachable structures, which is beneficial for component manufacturing and installation.

[0049] In this embodiment, the base 31 has an upward protrusion at the center of its bottom surface to form a bottom cavity 302 for accommodating the second clamping member 322; an annular cavity 303 is provided around the base 31, the bottom surface of the annular cavity 303 can be supported on a bearing surface such as the ground, and water can be added into the annular cavity 303 to cool the base 31.

[0050] Preferably, the housing 10, base 31, and pipe fitting 20 are all made of metal to meet combustion requirements. In other embodiments, the base 31 may also be modified in shape, for example, by omitting the bottom cavity 302 or the annular cavity 303, or by having a mounting plate with fixing holes on the mounting plate for fixing the base 31 to other equipment such as a smoke chamber, or by providing a handle on the pipe fitting 20 or the base 31 without changing the structure of the base 31, so that the user can hold and lift it.

[0051] In summary, the cold range hood of this embodiment uses threaded connections for detachable connection of related components, which is convenient for assembly operations as it only requires turning. Compared with other fixing methods such as hooks and clamps, the base fixing structure and pipe installation components of this application are easy to manufacture and assemble, and are stable and not easy to loosen after connection, which can also prevent users from injuring their fingers during operation.
