This application claims priority to Chinese Patent Application No. 202321793601.3, filed on Jul. 7, 2023, the entire contents of which are incorporated herein by reference.
The present application relates to the technical field of stoves, and in particular to a portable smokeless stove.
Stoves are mainly used in daily life for cooking and/or for heating.
Some stoves provide heat by burning woods, charcoals or other combustibles, but smoke is generated when the combustion materials cannot be fully burned. Especially when used indoors, the smoke cannot be diffused immediately when the air circulation is not good and will be inhaled by users, which causes some negative effects.
The main purpose of the present application is to provide a portable smokeless stove, aiming to improve the combustion effect of the combustion material in the stove and reduce the smoke.
In order to achieve the above objective, the portable smokeless stove provided by the present application includes a combustion cylinder, a separating net and first ventilation holes.

In an embodiment, the portable smokeless stove further includes: a cover movably provided on the combustion cylinder; the cover is provided with a flame gathering port communicated with the accommodating chamber of the combustion cylinder.
In an embodiment, the portable smokeless stove further includes a bracket movably provided on one side of the cover facing away from the combustion cylinder.
In an embodiment, the portable smokeless stove further includes: a supporting frame; the supporting frame includes a supporting platform and a supporting leg movably provided on the supporting platform, and one side of the supporting platform facing away from the supporting leg is connected to one side of the combustion cylinder facing away from the bracket.
In an embodiment, a connecting column is provided on one side of the supporting platform facing away from the combustion cylinder, and one end of the supporting leg is provided with a connecting rod rotatably provided in the connecting column; and the supporting frame is provided with a storage state and a supporting state; when in the storage state, the supporting leg fits with the supporting platform, and a supporting angle formed between the supporting leg and the supporting platform is 0 degree; when in the supporting state, a free end of the supporting leg is away from the supporting platform, and the supporting angle formed between the supporting leg and the supporting platform is not 0 degree.
In an embodiment, the portable smokeless stove further includes: an outer cylinder sleeved on a periphery of the combustion cylinder; a bottom of the outer cylinder is provided with a supporting block along a circumference of the cylinder wall, a sidewall of the outer cylinder is provided with a plurality of second ventilation holes, and each of the second ventilation holes is distributed along a circumference of the outer cylinder and is communicated with the accommodating chamber.
In an embodiment, an upper opening of the outer cylinder gradually expands toward a lower opening of the outer cylinder.
In an embodiment, an inner wall of the combustion cylinder is provided with a plurality of bosses integrally fixed on the inner wall of the combustion cylinder, and the separating net is provided on the bosses.
In an embodiment, the portable smokeless stove further includes: a collecting base movably provided on the side of the supporting platform facing away from the supporting leg; the collecting base includes a supporting wall and a collecting bottom plate connected to the supporting wall, one end of the supporting wall away from the collecting bottom plate is connected to a bottom of the combustion cylinder, and the collecting bottom plate is provided on the side of the supporting platform facing away from the supporting leg and is configured to collect a soot and/or other combustibles.

The present application provides a portable smokeless stove 1, as shown in
In an embodiment, the portable smokeless stove 1 is used for cooking on the table. The portable smokeless stove includes a combustion cylinder 11, a separating net 15, and first ventilation holes 11a. The upper and lower ends of the combustion cylinder 11 are provided with openings and are enclosed to form an accommodating chamber. A bottom of the accommodating chamber of the combustion cylinder 11 is provided with a separating net 15. The charcoals or other combustibles ignited are provided on the separating net 15 through the opening at the upper end. Since the first ventilation hole 11a of the combustion cylinder 11 is provided underneath the separating net 15, the air near the first ventilation hole 11a is quickly sucked in. Since the air around the separating net 15 in the chamber will expand during combustion and the air pressure will increase, the air will go up, and the smoke can be discharged through the first ventilation hole 11a at the upper end, thus forming an airflow direction, which can improve the combustion effect of the combustion material in the stove and reduce the smoke.
The combustion cylinder 11 is cylindrical with openings at the upper and lower ends and are enclosed to form the accommodating chamber, a supporting platform is bent outward at 90 degrees on a top of the combustion cylinder 11, and the accommodating chamber is mainly used for accommodating the heat source. It can be understood that the specific shape of the combustion cylinder 11 is not limited, and it can be cylindrical or square. For the convenience of portability, it is cylindrical in an embodiment. At the same time, the specific volume of the combustion cylinder 11 can be large or small. When used outdoors, an operable space is larger than a space used on the table. Therefore, appropriate adjustments made to the structure of the combustion cylinder 11 without any creative efforts by those skilled in the art is within the scope of the present application.
The separating net 15 can be detachably assembled with the combustion cylinder 11 through a pin or a boss structure. It can also be welded and fixed on an inner wall of the combustion cylinder. In consideration of the replacement of the separating net 15, in an embodiment, the pin structure is used for the detachable assembly of the separating net 15. When the pin structure is used, four through-holes are provided around the bottom of the combustion cylinder 11, two adjacent through-holes are provided at 90-degree, the four pins are respectively passed through the through-hole, then the separating net 15 is provided on the pin through the opening above the combustion cylinder 11 to be limited in the combustion cylinder 11. The method of using the boss structure is similar to that of the pin, and will be explained in detail later. It can be understood that, when the combustion cylinder 11 is cylindrical or in other shapes, the separating net 15 is provided to a corresponding shape so as to match the inner wall of the combustion cylinder 11 to the greatest extent for limit placement, and the shape is not limited here.
The upper and lower ends of the combustion cylinder 11 are provided with a plurality of first ventilation holes 11a communicated with the accommodating chamber along the circumference of the outer wall, and the first ventilation hole 11a at the lower end are lower than the separating net 15, so that charcoals or other combustibles can be exposed to the air. The first ventilation hole 11a at the lower end can cooperate with first ventilation hole 11a at the upper end to form an upward airflow in the cylinder, and the structure of the plurality of first ventilation holes 11a can improve the combustion efficiency of charcoals or other combustibles and make the combustion complete. It can be understood that the number and shape of the ventilation holes 11a are not limited, and the maximum ventilation area depends on the area of the wall of the combustion cylinder 11.

Every two adjacent supporting legs 162 are separated by 120 degrees. On the one hand, the supporting frame 16 can elongate the distance between the heat source on the separating net 15 and the table or other platforms to avoid damage. On the other hand, the supporting frame 16 can improve the stability of the entire stove even if it is placed on some uneven surfaces. It can be understood that the specific shape of the supporting frame 16 is not limited, as long as the combustion cylinder 11 can be stable on the supporting platform 161.
In an embodiment, as shown in
The supporting frame has a storage state and a supporting state. In the storage state, the supporting legs 162 fit with the supporting platform 161, and a supporting angle formed between the supporting legs 162 and the supporting platform 161 is 0 degrees.
