Abstract
Description
Technical fields:
[0001] This utility model belongs to the technical field of food smoking devices, and specifically refers to an easy-to-clean food smoking device. Background technology:
[0002] Smoking is an ancient food processing method that can extend the shelf life of food, enhance its flavor, improve its visual appeal, and even trigger the Maillard reaction to make it more aromatic. Traditionally, large wooden or metal containers are used, and firewood (such as cherry, walnut, or longan wood) is burned at the bottom of the container. The resulting smoke fills the container, ensuring that the food placed inside is enveloped in the smoke.
[0003] For small-batch food processing, such as restaurants only smoking certain dishes, existing technology has developed small-scale smoking devices. These devices consist of a burner installed at the air inlet of a pump. Firewood is placed on the burner and burned. The pump draws in the smoke from the combustion and then blows it out into the container where the food is placed to achieve the smoking effect. However, as the smoke passes through the pump, it leaves behind soot, which can clog the pump's pipes over time, reducing pump efficiency or rendering it unusable. Utility model content:
[0004] The technical problem to be solved by this utility model is to provide an easy-to-clean food smoking device, which improves upon existing smoking devices in order to extend their service life.
[0005] The technical solution of this utility model is to provide an easy-to-clean food smoking device, which includes:
[0006] A body having a top surface, a first side surface and a second side surface, the top surface being adjacent to the first side surface and the second side surface respectively, the first side surface and the second side surface being opposite sides, the body having a smoke inlet channel and a smoke outlet channel, the smoke inlet channel being formed by the top surface, the smoke outlet channel passing through the first side surface and the second side surface, and the smoke outlet channel and the air inlet section of the smoke inlet channel intersecting and communicating;
[0007] A burner is disposed on the top surface of the main body and passes through the smoke inlet passage;
[0008] An air intake pipe has one end located on the first side of the main body and passes through and connects to the air intake section of the exhaust channel, and the other end is used to connect to an air source.
[0009] An exhaust pipe, one end of which is located on the second side of the main body, and passes through and connects to the exhaust section of the smoke exhaust channel.
[0010] Preferably, the inner diameter of the exhaust section of the smoke exhaust channel is larger than the inner diameter of the intake section.
[0011] Preferably, the inner diameters of the air inlet section and the air outlet section of the smoke exhaust channel are the same, and the air inlet section and the air outlet section are connected in a stepped manner.
[0012] Preferably, the inner diameter of the air intake section of the smoke exhaust channel gradually widens from the first side towards the interior of the body (expansion), and the inner diameter of the air outlet section of the smoke exhaust channel gradually widens from the interior of the body towards the second side, so that the overall smoke exhaust channel gradually widens from the first side to the second side.
[0013] Preferably, the burner includes a combustion seat, a connecting pipe and a screen plate. The combustion seat has open ends. The connecting pipe is connected to and communicates with the combustion seat. The connecting pipe passes through the top surface of the body and through the smoke inlet channel. The screen plate is disposed between the combustion seat and the connecting pipe and has multiple mesh holes.
[0014] Preferably, the smoke inlet channel has a receiving section and a connecting section, the inner diameter of the receiving section is larger than the inner diameter of the connecting section, and the connecting section intersects and connects with the air inlet section of the smoke exhaust channel.
[0015] The burner's connecting pipe passes through the receiving section of the flue gas inlet channel.
[0016] Preferably, the combustion chamber is conical, and the connecting pipe is connected to the smaller diameter end of the combustion chamber.
[0017] Preferably, the exhaust section of the exhaust channel has a receiving section formed at the end of the second side, and one end of the exhaust pipe passes through the receiving section.
[0018] Preferably, the air source is a pump, and the air inlet pipe is connected to the air outlet of the pump.
[0019] Furthermore, the air source is a vacuum packaging machine, and the air inlet pipe is connected to the exhaust port of the vacuum packaging machine.
[0020] Compared with the prior art, the present invention has the following advantages:
[0021] By having the smoke inlet and exhaust channels intersect, the smoke generated by the burner does not pass through the gas source, but is instead carried by the airflow blown by the intake pipe and then into the exhaust pipe. This prevents the smoke from passing through the gas source, thus preventing soot residue from remaining in the gas source and avoiding damage to it. The exhaust channel and exhaust pipe are easy-to-clean or replaceable components. This structural design ensures that the service life of the gas source is not affected, and also allows for maintenance of the operation of this utility model at a lower cost.

Detailed implementation method:
[0030] The present invention will be further described below with reference to the accompanying drawings and specific embodiments:
[0031] Please see Figure 1 As shown, the smoking device of this utility model includes a body 10, a burner 20, an air inlet pipe 30, and an exhaust pipe 40.
[0032] Please see Figure 1 and Figure 2As shown, the body 10 has a top surface 101, a first side surface 102, and a second side surface 103. The top surface 101 is adjacent to the first side surface 102 and the second side surface 103, respectively, and the first side surface 102 and the second side surface 103 are opposite sides. The body 10 has a smoke inlet channel 11 and a smoke outlet channel 12. The smoke inlet channel 11 is formed by passing through the top surface 101, and the smoke outlet channel 12 passes through the first side surface 102 and the second side surface 103. The smoke outlet channel 12 intersects and communicates with the smoke inlet channel 11. The smoke outlet channel 12 has an air inlet section 121 and an air outlet section 122. The air inlet section 121 passes through the first side surface 102, and the air outlet section 122 passes through the second side surface 103. The inner diameter of the air outlet section 122 is larger than the inner diameter of the air inlet section 121. In one embodiment, as shown... Figure 2 As shown, the inner diameters of the air inlet section 121 and the air outlet section 122 of the smoke exhaust duct 12 are the same. The air inlet section 121 and the air outlet section 122 are connected in a stepped manner. The end of the air outlet section 122 extends through the second side surface 103 and forms a receiving section 123. In another embodiment, as shown... Figure 3 As shown, the inner diameter of the air inlet section 121 of the smoke exhaust channel 12 gradually widens from the first side 102 toward the interior of the body 10, and the inner diameter of the air outlet section 122 of the smoke exhaust channel 12 gradually widens from the interior of the body 10 toward the second side 103, so that the entire smoke exhaust channel 12 gradually widens from the first side 102 to the second side 103. In one embodiment, the smoke inlet channel 11 has a receiving section 111 and a connecting section 112. The inner diameter of the receiving section 111 is larger than the inner diameter of the connecting section 112, and the connecting section 112 intersects and connects with the air inlet section 121 of the smoke exhaust channel 12.
[0033] Please see Figure 1 and Figure 4 As shown, the aforementioned burner 20 is disposed on the top surface 101 of the body 10 and passes through the smoke inlet channel 11. The burner 20 includes a combustion seat 21, a connecting pipe 22, and a sieve plate 23. The combustion seat 21 is open at both ends and can be conical. The connecting pipe 22 is connected to and communicates with the smaller diameter end opening of the combustion seat 21. The connecting pipe 22 passes through the top surface of the body 10 and through the receiving section 111 of the smoke inlet channel 11. In one embodiment, the connecting pipe 22 is screwed and fixed in the receiving section 111 of the smoke inlet channel 11. The sieve plate 23 is disposed between the combustion seat 21 and the connecting pipe 22, and the sieve plate 23 has a plurality of mesh holes 231.
[0034] Please see Figure 1 and Figure 4As shown, one end of the aforementioned air intake pipe 30 is disposed on the first side surface 102 of the main body 10, and passes through and communicates with the air intake section 121 of the smoke exhaust channel 12. The other end of the air intake pipe 30 is connected to an air source 50. In one embodiment, as... Figure 1 As shown, the air source 50 is a pump, and the air inlet pipe 30 is connected to the air outlet 51 of the pump; in another embodiment, as... Figure 5 As shown, the gas source 50A is a vacuum packaging machine. The air inlet pipe 30 is connected to the exhaust port 52A of the vacuum packaging machine. The gas discharged when the vacuum packaging machine is performing vacuum operation is used as the gas source for the air inlet pipe 30.
[0035] Please see Figure 1 and Figure 4 As shown, the aforementioned exhaust pipe 40 is disposed on the second side 103 of the main body 10 and passes through and communicates with the exhaust section 122 of the exhaust channel 12. In one embodiment, one end of the exhaust pipe 40 is screwed into the receiving section 123.
[0036] Please see Figure 6 and Figure 7 As shown, in use, the end of the exhaust pipe 40 is placed in the food container 60, and the firewood 70 to be burned is placed in the combustion seat 21 of the burner 20, and blocked by the sieve plate 23 to prevent it from falling into the connecting pipe 22. When the gas source 50 is turned on, the gas source 50 blows gas into the air intake pipe 30. The gas is pushed by the gas source 50 through the air intake pipe 30, the air intake section 121 of the smoke exhaust channel 12, the air outlet section 122 of the smoke exhaust channel 12, and finally flows out of the exhaust pipe 40 into the food container 60. At this time, the firewood 70 is lit. Since the combustion seat 21 is connected to the air intake section 121 of the smoke exhaust channel 12 through the connecting pipe 22, the smoke produced by the burning firewood 70 will be carried by the airflow generated by the gas source 50 and carried into the air intake section 121, and finally enter the food container 60 with the airflow to produce a smoking effect on the food inside.
[0037] Furthermore, since the inner diameter of the exhaust section 122 of the smoke exhaust channel 12 is larger than that of the intake section 121, based on the principle that pressure and volume are inversely proportional, the larger exhaust section 122 forms a lower pressure area. Moreover, the gas system flows from the area of high pressure to the area of low pressure. This causes the airflow to increase from the intake section 121 to the exhaust section 122 due to the gas pressure, in addition to the power of the gas source 50. This effectively drives the smoke generated by the burner 20, so that most of the smoke after combustion can be introduced into the food container 60, which can increase the combustion efficiency of the firewood 70.
[0038] By blowing gas through the air source 50 to the air intake pipe 30 to generate airflow, the smoke produced by the firewood 70 does not flow into the air source 50, but instead enters the food container 60 through the smoke exhaust channel 12 and the exhaust pipe 40. Therefore, there will be no residual soot in the air source 50 that could damage it. The smoke exhaust channel 12 and the exhaust pipe 40 do not involve electronic or mechanical components and can be easily cleaned or replaced. As a result, the service life of the air source 50 is not affected, and the cost of cleaning or replacing the smoke exhaust channel 12 and the exhaust pipe is relatively low, which can save money for the user.
[0039] The above description only illustrates preferred embodiments of the present invention and should not be construed as limiting the scope of the claims. All equivalent procedural modifications made using this specification are included within the patent protection scope of this invention.
