Description

Technical Field

[0001] This utility model relates to the field of household fuel stoves, specifically a swirl combustion household fuel stove structure. Background Technology

[0002] With the development of bio-ethanol fuel oil, fuel prices have become relatively cheap and have gained increasing popularity. As a result, most households now have fuel stoves. Currently, fuel stoves on the market mainly consist of a panel, a burner core, a burner frame surrounding the burner core, an ignition switch, an igniter, a heater, and fuel lines. Fuel stoves primarily use a heater to heat the fuel. When the fuel is heated, it produces vapors, which are then sprayed from atomizing nozzles into the combustion zone. The igniter then ignites the vapors for cooking.

[0003] However, the mixing of oil and oxygen in commercially available fuel stoves is not uniform enough. That is, the oil and gas sprayed from the atomizing nozzle directly enter the combustion zone after contacting the air, resulting in incomplete combustion and relatively low thermal efficiency.

Detailed Implementation

[0015] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0016] like Figure 1-8 As shown, the present invention provides a swirl-burning household fuel stove structure, including a supporting base plate 10, a surrounding plate 11, a gas supply pipe 12, an air inlet pipe body 13, and a sealing top cover 14.

[0017] The support base plate 10 is provided with a gas inlet 101. It should be understood that the support base plate 10 is installed on the burner frame of the oil stove.

[0018] A surrounding plate 11 is disposed around the top surface of the supporting base plate 10, wherein an air inlet 101 is disposed within the surrounding plate 11. It should be understood that the surrounding plate 11 is relatively high, separating the supporting base plate 10 to form an inner cavity, within which the air inlet 101 is disposed.

[0019] The air supply pipe 12 is arranged around the outside of the enclosure 11. One end of the air supply pipe 12 passes through the supporting base plate 10 and is exposed below the supporting base plate 10. The other end of the air supply pipe 12 is located at the top of the outer wall of the enclosure 11, and the exhaust direction of the other end of the air supply pipe 12 is horizontal. It should be understood that the air supply pipe 12 is relatively long, wrapping around the enclosure 11 several times. Air enters from one end of the air supply pipe 12 and exits from the other end. Since the exhaust direction of the other end of the air supply pipe 12 is horizontal, the air exiting from the other end of the air supply pipe 12 enters the combustion zone in a spiral shape, allowing the air to mix fully with the fuel, resulting in more complete combustion of the fuel and relatively higher thermal efficiency.

[0020] It is worth noting that in this embodiment, one end of the air supply pipe 12 can be disconnected from any power source, allowing the air from the supporting base plate 10 to automatically enter the air supply pipe 12. In other embodiments, one end of the air supply pipe 12 is equipped with an air pump, which delivers outside air to the air supply pipe 12 at a certain pressure, so that the air discharged from the other end of the air supply pipe 12 has a certain pressure, making the air rotation effect better.

[0021] An air intake pipe 13 is disposed on the bottom surface of a support base plate 13. One end of the air intake pipe 13 is connected to the air inlet 101 of the support base plate 10, and the other end of the air intake pipe 13 is provided with an air inlet 131. The air inlet 131 at the other end of the air intake pipe 13 corresponds to and is spaced apart from the atomizing nozzle 20 of the fuel stove, so that the oil and gas sprayed from the atomizing nozzle 20 directly enters the air intake pipe 13. It should be understood that because the air inlet 131 is spaced apart from the atomizing nozzle 20, the oil and gas sprayed from the atomizing nozzle 20 first mixes with air before entering the air inlet 131.

[0022] It is worth noting that in some embodiments, in order to save power, one end of the air supply pipe 12 is oriented toward the atomizing nozzle 20, that is, the atomizing nozzle 20 and the air inlet 131 are in the same straight line, while the atomizing nozzle 20 and one end of the air supply pipe 12 are not in the same straight line, so that the oil and gas sprayed by the atomizing nozzle 20 drives the surrounding air to flow, allowing the flowing air to enter one end of the air supply pipe 12.

[0023] The sealing cover 14 is provided on the top surface of the supporting base plate 10 to cover the enclosure 11.

[0024] In this embodiment, the sealing cover 14 includes an annular plate 141 surrounding the surrounding plate 11 and an exhaust panel 142 connected to the top of the annular plate 141. The exhaust panel 142, the supporting base plate 10, and the surrounding plate 11 form a first mixing cavity 1401 communicating with the air supply port 101. The annular plate 141 (including part of the exhaust panel 142) and the surrounding plate 11 form a second mixing cavity 1402 for accommodating the air supply pipe 12. The surrounding plate 11 is provided with a connecting hole that connects the first mixing cavity 1401 and the second mixing cavity 1402. The exhaust panel 142 is provided with a plurality of first exhaust ports 1421 spaced apart.

[0025] It should be understood that after the oil and gas sprayed from the atomizing nozzle 20 enters the air intake pipe 13 through the air intake hole 131, it enters the first mixing chamber 1401 through the air delivery hole 101. At this time, the oil and gas and air are also mixed in the first mixing chamber 1401. Then, it enters the second mixing chamber 1402 through the connecting hole. At this time, the oil and gas and air are also mixed in the second mixing chamber 1402. Finally, it is discharged from the multiple first exhaust holes 1421 between the exhaust panels 142 for combustion. That is, the area above the exhaust panel 142 is the combustion area.

[0026] Preferably, the height of the enclosure 11 is smaller than the height of the annular plate 141, and the exhaust panel 142 is inclined downward from the top of the annular plate 141 toward the center of the supporting base plate 10.

[0027] Furthermore, the top of the enclosure 11 is connected to the bottom of the exhaust panel 142, wherein the top of the enclosure 11 is provided with a plurality of connecting holes at intervals along its length, so that the oil and gas in the first mixing chamber 1401 can enter the second mixing chamber 1402 evenly.

[0028] In this embodiment, the center of the exhaust panel 142 is provided with an opening 1422 that communicates with the first mixing cavity 1401. A center ignition cover 15 is provided in the opening 1422, and a plurality of second exhaust holes 151 are provided at intervals in the center ignition cover 15.

[0029] Preferably, the center ignition cover 15 is cylindrical, with the top of the center ignition cover 15 sealed and the bottom open. The edge of the opening of the exhaust panel 142 extends upward with an annular protrusion 1423. The inner wall of the annular protrusion 1423 is provided with an internal thread. The outer wall of the bottom end of the center ignition cover 15 is provided with an external thread that is threaded to the internal thread. A plurality of second exhaust holes 151 are spaced apart on the side wall of the center ignition cover 15.

[0030] Furthermore, the first exhaust port 1421 is in the shape of an elongated arc, and the second exhaust port 151 is in the shape of a circle.

[0031] In other embodiments, the air supply pipe 12 includes a first air supply pipe and a second air supply pipe, which are arranged around the perimeter of the enclosure 11 at intervals. One end of the first air supply pipe and one end of the second air supply pipe pass through the supporting base plate 10 and are exposed on both sides below the supporting base plate 10. The other ends of the first air supply pipe and the other ends of the second air supply pipe are located on both sides of the top of the outer wall of the enclosure 11, and the exhaust direction of the other end of the first air supply pipe is the same as the exhaust direction of the other end of the second air supply pipe, so that the air discharged by the first air supply pipe and the second air supply pipe is in the same direction.

[0032] Furthermore, the sealing cover 14 also includes an annular base plate 143 surrounding the bottom of the annular plate 141, wherein the annular base plate 143 has a protruding edge 1431 extending downward from its edge, the supporting base plate 10 is circular in shape, and the area of ​​the supporting base plate 10 is equal to the area of ​​the inner hole formed by the protruding edge 1431.
