[0045] The adjustable-power oil heater provided in this embodiment has the following advantages:
[0046] (1) Precise adjustment of firepower: Through the nesting structure of the lifting cover and the lamp wick, the airflow can be continuously controlled, so that the flame size can be flexibly adjusted according to cooking needs;
[0047] (2) The design of wick immersion in oil box ensures continuous supply of fuel, avoids midway extinguishing, and ensures long-term combustion stability;
[0048] (3) The outer shell integrates the pot rack and oil box, which is simple in structure and easy to carry, making it suitable for use in various outdoor scenarios;
[0049] (4) The support bracket isolates the oil box from the tabletop to prevent high temperature conduction from damaging the load-bearing surface, and also supports installation on uneven tabletops;
[0050] (5) The split oil box design facilitates cleaning and replacement of the lamp wick; the centralized fixing structure for multiple lamp wicks simplifies the operation steps.
[0051] (6) Multiple lamps arranged in a ring and synchronous lifting control ensure that heat is evenly distributed on the bottom of the cookware, avoiding local scorching.
[0052] (7) The gear and rack transmission mechanism enables the stable lifting of the lifting cover, and the guard plate protects the transmission components from contamination and extends their service life;
[0053] (8) The energy-concentrating cover reduces heat loss by reflecting heat energy, and the windproof design enhances its adaptability to harsh environments; the multi-level pot rack is compatible with different cookware and is non-slip.
[0054] (9) The oil filling port screw cap design enables quick opening and closing, preventing fuel evaporation or leakage and improving safety during use.
[0055] The working principle of the adjustable-power oil heater provided in this embodiment is as follows:
[0056] like Figure 1 After installing the oil stove as shown, fuel is introduced into the oil box 2 through the oil inlet 205. The asbestos wick 3 will absorb the fuel. Light the wick 3 with a lighter or match, and place the pot on the pot rack 5 or pot rack 12 to begin cooking. When the heat needs to be adjusted, rotate the knob 10. The knob 10 will drive the lifting plate 6 to rise and fall through the gear 8 and rack 7, and the lifting cover 4 connected to the lifting plate 6 will rise and fall accordingly. When the lifting cover 4 is raised, the wick 3 has less air contact, so the flame becomes smaller; when the lifting cover is lowered, the wick 3 has less air contact, so the flame becomes larger. When the flame needs to be extinguished, adjust the lifting cover 4 to its highest position. At this time, the top of the wick 3 is lower than the top of the lifting cover 4, and the wick 3 will extinguish due to insufficient oxygen; moreover, for pots of normal size, the top of the lifting cover 4 will touch the bottom of the pot, thus extinguishing the flame quickly.
[0057] The above description is merely a preferred embodiment of this utility model. It should be understood that this utility model is not limited to the forms disclosed herein and should not be construed as excluding other embodiments. It can be used in various other combinations, modifications, and environments, and can be altered within the scope of the concept described herein through the above teachings or related technologies or knowledge.
