Description

Technical Field

[0001] The utility model relates to the technical field of stoves, in particular to an alcohol-based liquid fuel stove. Background Art

[0002] At present, stoves for methanol or other alcohol-based liquid fuels usually include a combustion chamber, a nozzle arranged in the combustion chamber, an ignition device arranged in the combustion chamber, a container containing liquid fuel, a delivery pump and a fan. The fan is connected to the combustion chamber through a pipeline. A vaporization hood is provided on the upper end cover of the combustion chamber. When working, the delivery pump pumps the liquid fuel in the container to the nozzle, and then the nozzle atomizes the liquid fuel and sprays it into the combustion chamber. The fan supplies air to the combustion chamber, and the ignition device ignites the atomized liquid fuel so that the flame emerges from the through hole of the vaporization hood. At the same time, the atomized liquid fuel is also sent to the vaporization hood by the wind. Subsequently, due to the increase in the temperature of the vaporization hood, the atomized liquid fuel is vaporized by the vaporization hood and then ignited. During operation of the existing stove, due to the large overall space of the combustion chamber, the wind delivered by the fan cannot completely transport all the atomized liquid fuel sprayed from the nozzle to the vaporization hood, causing part of the liquid fuel to fall to the bottom of the combustion chamber. The bottom of the combustion chamber is far away from the vaporization hood, resulting in a low temperature and unable to effectively vaporize the liquid fuel, resulting in fuel residue and waste.

[0024] Reference Figure 1 According to an embodiment of the utility model, an alcohol-based liquid fuel cooker includes an air chamber 110, a gasification baffle 120, a gasification hood 130, a nozzle 200, an ignition device 300, a liquid fuel supply device 400 and a fan 500. The gasification baffle 120 is arranged in the air chamber 110. The lower side of the gasification baffle 120 and the air chamber 110 are enclosed to form a first cavity 140. The gasification baffle 120 is provided with a plurality of first through holes 121; the gasification hood 130 is provided with a plurality of second through holes 131. The gasification hood 130 is located above the gasification baffle 120. The gasification hood 130 is connected or in contact with the gasification baffle 120, and the gasification hood 130 and the gasification baffle 120 enclose a second cavity 150; the nozzle 200 is used to spray liquid fuel into the second cavity 150; the ignition device 300 is arranged on one side of the nozzle 200; the liquid fuel supply device 400 is connected to the nozzle 200 through a pipeline; the air outlet of the fan 500 is connected to the first cavity 140 through a pipeline; wherein the gasification hood 130 can heat the gasification baffle 120 so that the gasification baffle 120 can gasify the liquid fuel intercepted by it.

[0025] During the operation of the alcohol-based liquid fuel stove provided by the utility model, the air delivered by the fan 500 first fills the first cavity 140, then is delivered into the second cavity 150 through each first through hole 121 of the gasification baffle 120, and finally is ejected from the second through hole 131 on the gasification hood 130. The nozzle 200 sprays liquid fuel to the second cavity 150, so that the liquid fuel is atomized. The atomized liquid fuel can be transported to the gasification hood 130 with the wind. The ignition device 300 ignites the atomized liquid fuel, so that flames are ejected from the second through hole 131 of the gasification hood 130. The gasification hood 130 can gasify the liquid fuel after being heated by the flame, wherein: The gasification baffle 120 can intercept the liquid fuel that falls into the second cavity 150. Since the first through hole 121 of the gasification baffle 120 supplies air to the second cavity 150, droplets of liquid fuel can be prevented from falling into the first cavity 140 from the first through hole 121 of the gasification baffle 120. Since the gasification baffle 120 and the gasification hood 130 are in contact or connected to each other, the gasification hood 130 can also heat the gasification baffle 120, so that the gasification baffle 120 can gasify the liquid fuel that falls onto the gasification baffle 120, and then the gasified fuel can be transported to the gasification hood 130 with the wind for combustion, thereby reducing fuel residue and waste.

[0026] In addition, the gasification baffle 120 can also heat the air passing through the first through hole 121, so that the temperature of the air entering the second cavity 150 is higher, thereby improving the gasification efficiency of the liquid fuel.

[0027] According to some embodiments of the utility model, the gasification baffle 120 is provided with a third through hole 122 upward, the lower end of the nozzle 200 is located in the first cavity 140, and the upper end of the nozzle 200 is inserted into the third through hole 122. Through the above arrangement, the second cavity 150 does not need to reserve a height for installing the nozzle 200, and the overall height of the second cavity 150 is reduced, thereby reducing the space size of the second cavity 150, increasing the upper temperature limit that can be reached inside the second cavity 150, and improving the gasification efficiency of the liquid fuel.

[0028] It is conceivable that in other embodiments, the nozzle 200 may be disposed in other ways. For example, the nozzle 200 is disposed horizontally, and the outlet of the nozzle 200 is connected to the second cavity 150 .

[0029] According to some embodiments of the utility model, the liquid fuel supply device 400 includes a delivery pump 410 and a container 420 for containing liquid fuel, the container 420 is connected to the delivery pump 410 through a pipeline, and the delivery pump 410 is connected to the nozzle 200 through a pipeline. Therefore, the delivery pump 410 can pump the liquid fuel in the container 420 to the nozzle 200 so that the nozzle 200 can spray the liquid fuel to the second cavity 150. With the above arrangement, the stove can be stopped by simply controlling the delivery pump 410 to stop working so that the nozzle 200 cannot spray liquid fuel, and the stopping of the fire is simple, convenient and fast.

[0030] It is conceivable that in other embodiments, the above-mentioned liquid fuel supply device 400 may also adopt other settings. For example, the liquid fuel supply device 400 includes a container 420 for containing liquid fuel, and the container 420 has a piston built in it. The piston is connected to the cylinder, so that the piston is driven by the cylinder to move in the container 420 to squeeze the liquid fuel, thereby pumping the liquid fuel in the container 420 to the nozzle 200.

[0031] According to some embodiments of the present invention, the gasification hood 130 is connected to an annular connection portion 132, and the connection portion 132 is connected to the gasification baffle 120. Therefore, the gasification hood 130 can transfer heat to the gasification baffle 120 through the annular connection portion 132 to achieve heating of the gasification baffle 120. In addition, the annular connection portion 132 serves as a side wall of the second cavity 150 to achieve the closure of the side of the second cavity 150.

[0032] In some embodiments, the ignition device 300 is horizontally disposed in the second cavity 150 , with one end thereof close to the upper end of the nozzle 200 and the other end passing through the connecting portion 132 , so that the ignition device 300 can effectively ignite the liquid fuel in the second cavity 150 .

[0033] It is conceivable that in other embodiments, the ignition device 300 may also be arranged in other ways. For example, the ignition device 300 is arranged vertically, the ignition device 300 is passed through the gasification baffle 120, and the head of the ignition device 300 is located in the second cavity 150 and close to the nozzle 200.

[0034] According to some embodiments of the present invention, the vaporization baffle 120 is a metal baffle, and thus the vaporization baffle 120 has better heat transfer performance and can more efficiently receive the heat transferred by the vaporization hood 130. The temperature of the vaporization baffle 120 rises quickly, and the liquid fuel dropped on the vaporization baffle 120 can be vaporized more quickly.

[0035] According to some embodiments of the present invention, the gasification hood 130 is a metal hood, so that the temperature of the gasification hood 130 rises quickly and the heat transfer performance is good, so that the liquid fuel can be gasified more efficiently. In addition, the gasification hood 130 can transfer heat to the gasification baffle 120 more quickly.

[0036] According to some embodiments of the present invention, the plurality of first through holes 121 are evenly arranged, thereby improving the uniformity of air intake into the second cavity 150 .

[0037] According to some embodiments of the utility model, the bottom wall surface of the first cavity 140 is a part of a spherical surface. Through the above arrangement, the distance between the middle position of the bottom wall of the first cavity 140 and the gasification baffle 120 is relatively large, which can meet the installation requirements of the nozzle 200. At the same time, the distance between the bottom wall of the first cavity 140 and the gasification baffle 120 gradually decreases from the middle to the outside, making the overall space of the first cavity 140 smaller, ensuring the pressure of the air in the first cavity 140, and reducing the resistance to the flowing air, thereby ensuring the wind force of the first cavity 140 to send air to the second cavity 150.

[0038] According to some embodiments of the present invention, the surface of the gasification hood 130 facing the gasification baffle 120 is a part of a spherical surface. Therefore, the distance between the lower surface of the gasification hood 130 and the gasification baffle 120 gradually decreases from the middle to the outside, ensuring that the distance between the middle position of the lower surface of the gasification hood 130 and the nozzle 200 is sufficient, so that the liquid fuel sprayed by the nozzle 200 can be more fully dispersed in the second cavity 150.

[0039] According to some embodiments of the utility model, the air chamber 110 is provided with an air inlet 111 connected to the first cavity 140. The air inlet 111 is connected to the air outlet of the fan 500 through a pipe. The direction of the air inlet 111 is in the horizontal direction. Therefore, the wind provided by the fan 500 enters the first cavity 140 in the horizontal direction, and is discharged from the first through hole 121 on the vaporization baffle 120 after the wind fills the first cavity 140. Therefore, the uniformity of the air outlet from the multiple first through holes 121 can be improved.

[0040] According to some embodiments of the present invention, the air chamber 110 is a heat-insulating air chamber 110 to reduce the heat transferred outward from the air chamber 110 and to protect objects outside the air chamber 110 .

[0041] In some embodiments, the above-mentioned alcohol-based liquid fuel stove also includes a shell 600, an opening 610 is provided at the upper end of the shell 600, the above-mentioned air chamber 110 is provided in the shell 600, the gasification hood 130 is located at the opening 610, and the fan 500, the container 420, and the delivery pump 410 are provided in the shell.

[0042] The technical features of the above-described embodiments may be arbitrarily combined. To make the description concise, not all possible combinations of the technical features in the above-described embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.

[0043] The embodiment is described in detail above in conjunction with the accompanying drawings, but the present invention is not limited to the above embodiment, and various changes can be made within the knowledge scope of ordinary technicians in the technical field without departing from the present purpose.
