[0033] The present invention will be further described below with reference to the accompanying drawings and specific embodiments:

[0034] See Figures 1 to 9 As shown, an adjustable flame oil stove includes a stove body 1 and a burner head 2. The stove body 1 has a fuel chamber 12 for storing liquid fuel. The burner head 2 includes a connecting seat 22 connected to the stove body 1, and a wick 21 is mounted on the connecting seat 22. The wick 21 can draw liquid fuel from the fuel chamber 12. An adjusting seat 3 is movably mounted on the stove body 1, and an adjusting hole 31 is provided on the adjusting seat 3. The wick 21 is placed in the adjusting hole 31 and extends out of the adjusting hole 31. A driving component 5 is provided on the stove body 1. The driving component 5 can control the relative movement between the adjusting seat 3 and the burner head 2, and the relative movement between the adjusting hole 31 and the wick 21, thereby adjusting the length of the wick 21 extending out of the adjusting hole 31, and thus adjusting the flame size on the wick 21. In this structure, the driving component 5 can adjust the length of the wick 21 extending out of the adjusting hole 31, thereby adjusting the range of fuel combustion on the wick 21 during the use of the oil stove, and thus adjusting the flame size of the oil stove.

[0035] When the wick 21 extends a longer distance, the combustion area of ​​the fuel on the wick 21 is larger, resulting in higher combustion efficiency and a larger flame. Conversely, when the wick 21 extends a shorter distance, the combustion area is smaller, resulting in lower combustion efficiency and a smaller flame. When the end of the wick 21 is retracted into the adjusting hole 31, only the end of the wick 21 burns, leading to the lowest combustion efficiency and a minimal or even extinguished flame. This structure allows users to flexibly control the flame size of the oil stove, making it convenient for operation. Furthermore, the adjusting hole 31 does not impede airflow during combustion, promoting complete combustion of the fuel on the wick 21, reducing fuel waste, and minimizing the generation of harmful gases and black smoke during combustion.

[0036] The connecting seat 22 of this utility model is provided with a guide tube 222, which passes through the adjustment hole 31. The lamp wick 21 passes through the guide tube 222, and the lamp wick 21 extends out from the end of the guide tube 222 and can pass into the adjustment hole 31. The driving component 5 controls the movement of the adjusting seat 3. The guide tube 222 can guide the movement of the adjusting seat 3. The setting of the guide tube 222 not only facilitates the fixed installation of the lamp wick 21, but also guides the movement of the adjusting seat 3, which is conducive to the stable movement of the adjusting seat 3 and makes it convenient for the user to adjust the size of the oil furnace flame.

[0037] Preferably, both the lamp wick 21 and the guide tube 222 of this invention extend vertically, and the driving component 5 can drive the adjusting seat 3 to rise and fall, thereby adjusting the length of the lamp wick 21 extending out of the adjusting hole 31.

[0038] The adjusting component can drive the adjusting seat 3 to rise and fall through a gear and rack structure or a screw and nut structure. The driving component 5 is provided with a gear part or a screw part, and the adjusting seat 3 is provided with a rack part or a threaded hole. Controlling the rotation of the driving component 5 can make the adjusting seat 3 rise and fall. The adjusting component can also drive the adjusting seat 3 to rise and fall through a scissor lifting structure or a linkage structure. This structure is a common mechanical structure, and users can implement this technical solution according to their own knowledge.

[0039] In this utility model, the preferred driving component 5 drives the adjusting seat 3 to move through an eccentric structure. The driving component 5 is rotatably mounted on the furnace body 1, and the driving component 5 is provided with an eccentric part 53. By controlling the rotation of the driving component 5, the eccentric part 53 can abut against the adjusting seat 3 and drive the adjusting seat 3 to move. The structure of the eccentric part 53 is simple and convenient for production and processing.

[0040] To enable the adjusting seat 3 to maintain different relative positions with the lamp wick 21, the manufacturer can increase damping and friction on the rotation of the adjusting seat 3. Through damping and friction, the driving component 5 can be kept in different states. The manufacturer can not only change the damping and friction during the movement of the driving component 5 by adding separate damping and friction components (the damping and friction components are not specifically shown in the accompanying drawings of this utility model, but those skilled in the art can implement this technical solution based on their own knowledge); the manufacturer can also keep the driving component 5 in different states through the friction between the driving component 5 and the furnace body 1 or the furnace body 1 itself. This structure is the technical solution shown in the accompanying drawings of this utility model.

[0041] The adjusting seat 3 is provided with a groove 32, and the eccentric part 53 passes through the groove 32, controlling the rotation of the driving component 5. The eccentric part 53 can abut against the side wall of the groove 32 and drive the adjusting seat 3 to move. The groove 32 has a simple structure, which is convenient for production and processing. The structure of the groove 32 facilitates the eccentric part 53 to drive the adjusting seat 3 to reciprocate, avoiding the adjusting seat 3 from getting stuck during the adjustment of the oil furnace and affecting the normal adjustment of the oil furnace. In this embodiment, the upper end of the eccentric part 53 is lower than the upper end of the adjusting hole 31. During the burning process of the lamp wick 21, the burning position will be above the adjusting hole 31. This structure can prevent the eccentric part 53 from being burned by the flame, which is beneficial to extending the service life of the eccentric part 53 and the groove 32.

[0042] The driving component 5 described in this invention includes a rotating rod 52, a groove 32 extending to one side of the rotating rod 52, and an eccentric portion 53 abutting against the end of the groove 32, thereby keeping the adjusting seat 3 in its extreme position. Controlling the unidirectional rotation of the driving component 5 drives the adjusting seat 3 to move, gradually increasing or decreasing the length of the wick 21 extending through the adjusting hole 31, thus gradually increasing or decreasing the size of the flame on the wick 21. This structure allows the user to control the gradual increase or decrease, facilitating the adjustment of the oil stove's flame to its maximum or minimum. Furthermore, the eccentric portion 53 abutting against the end of the groove 32 keeps the adjusting seat 3 in its extreme position, preventing accidental rise or fall of the adjusting seat 3 during oil stove use, thus facilitating user operation of the oil stove.

[0043] Preferably, the furnace body 1 and the connecting seat 22 are respectively provided with a first hinge hole 13 and a second hinge hole, and the rotating rod 52 is rotatably connected to the first hinge hole 13 and the second hinge hole respectively. One end of the rotating rod 52 extends out from the side of the furnace body, and a knob part 51 is provided at the end of the rotating rod 52 extending out from the side of the furnace body.

[0044] In this embodiment, the adjusting seat 3 is provided with two sets of grooves 32, which are spaced apart. The eccentric part 53 cooperates with the two sets of grooves 32 respectively. The two sets of grooves 32 facilitate the force on the adjusting seat 3 and facilitate the driving component 5 to control the stable movement of the adjusting seat 3. In this embodiment, the burner head 2 is provided with several lamp wicks 21, and the adjusting seat 3 is provided with several adjusting holes 31 corresponding to the lamp wicks 21. The lamp wicks 21 surround the outer periphery of the two sets of grooves 32.

[0045] The furnace body 1 or the furnace head 2 is equipped with a fire extinguishing cover 4, which can cover the wick 21 and extinguish the flame on the wick 21. The fire extinguishing cover 4 not only extinguishes the flame on the wick 21, but also prevents gaseous objects from contacting the wick 21 when the oil furnace is not in use, avoids fuel on the wick 21 from contaminating gaseous objects, and facilitates the storage and transportation of the oil furnace.

[0046] In this invention, a limiting wall 34 is provided on the connecting seat 22 or the furnace body 1. The extinguishing cover 4 has an extinguishing chamber, and the side wall of the extinguishing chamber can abut against the limiting wall 34, preventing the extinguishing cover 4 from contacting the wick 21. The limiting wall 34 prevents the extinguishing cover 4 from contacting the wick 21, reducing the possibility of fuel contamination on the extinguishing cover 4 during use, facilitating placement of the extinguishing cover 4, and making it convenient for the user. In this embodiment, the adjusting seat 3 extends upward to form a protrusion, the adjusting hole 31 is located in the protrusion, and the limiting wall 34 is the side wall of the protrusion.

[0047] The top of the burner head 2 is provided with a cavity 221, in which the lamp wick 21 and the adjusting seat 3 are both disposed. The driving component 5 can control the adjusting seat 3 to rise and fall within the cavity 221. The cavity 221 protects the lamp wick 21 and the adjusting seat 3 from accidental contact. In this embodiment, at least three supports 11 are provided on the outer periphery of the cavity 221, the upper end of the lamp wick 21 protrudes from the cavity 221, and several supporting feet 14 are provided at the lower end of the furnace body 1.

[0048] In this invention, the fuel chamber 12 is located below the recessed cavity 221, and the bottom of the recessed cavity 221 is provided with an oil inlet hole 223 communicating with the fuel chamber 12. This structure eliminates the need to disassemble the burner head 2 during fuel addition, facilitating the user's addition of fuel to the fuel chamber 12 and making the stove more convenient to use. In this embodiment, the adjusting seat 3 is provided with a clearance portion 33, which is located above the oil inlet hole 223, allowing fuel to pass through the clearance portion 33 and the oil inlet hole 223 and enter the fuel chamber 12.

[0049] The above embodiments are merely preferred embodiments of the present utility model and are not intended to limit the scope of protection of the present utility model. Therefore, all equivalent changes made to the structure, shape, and principle of the present utility model should be covered within the scope of protection of the present utility model.
