Description

[Technical Field]

[0001] This invention belongs to the technical field of liquid fuel stoves, and particularly relates to a tubular vaporization core applied to a fuel stove and a combustion method for the fuel stove core. [Background Technology]

[0002] Currently, stoves that use liquid alternative fuels for vaporization all use electric heating in the stove cavity to vaporize and burn the liquid fuel once the temperature reaches the physical calibration value. However, these vaporization stoves can have structural leakage problems, leading to fuel waste and safety hazards. In addition, using electric heating can lead to long-term use of AC power, and the rate of temperature increase is affected by the size of the cavity, which affects the user experience. [Summary of the Invention]

[0003] To address the problem of low heating efficiency caused by electric heating in the aforementioned vaporization stoves, this invention provides a tubular vaporization core for use in fuel stoves and a combustion method for the fuel stove core.

[0004] This invention is achieved through the following technical solution:

[0005] A tubular vaporization stove core used in fuel stoves includes a stove core body with a combustion chamber, a tubular heater disposed on the stove core body, and an injector disposed in the combustion chamber. One end of the tubular heater is connected to an oil supply pipe, and the other end is connected to the injector in the combustion chamber. The tubular heater is disposed on the outer periphery of the stove core body or on the inner wall of the combustion chamber so that the tubular heater can be heated when the stove core body is burning.

[0006] The tubular vaporization stove core used in fuel stoves as described above also has a return port at the bottom of the stove core body.

[0007] As described above, in the tubular vaporization burner core used in fuel stoves, the tubular heater is coiled around the outer periphery of the burner core body or the inner wall of the combustion chamber.

[0008] As described above, in the tubular vaporization burner core used in fuel stoves, the tubular heater is located on the outer periphery of the burner core body.

[0009] The tubular vaporization burner core used in fuel stoves as described above has a spiral-designed embedding groove on the outer peripheral wall of the burner core body.

[0010] As described above, in the tubular vaporization burner core used in fuel stoves, the tubular heater is located on the inner wall of the combustion chamber.

[0011] As described above, the tubular vaporization stove core used in fuel stoves has a through hole on its outer peripheral wall that connects to the combustion chamber. One end of the tubular heater passes through the through hole and is connected to the oil supply pipe on the outside.

[0012] The tubular vaporization burner core used in fuel stoves as described above is further provided with an igniter and a burner cap inside the combustion chamber.

[0013] As described above, the tubular vaporization burner core used in fuel stoves has an outwardly flared edge located above the combustion chamber of the burner core body, and the edge has several ventilation holes.

[0014] A method for igniting the burner core of a fuel stove, comprising the following steps:

[0015] a. Liquid fuel is introduced into the combustion chamber through a tubular heater;

[0016] b. The liquid fuel in the combustion chamber is burned by an igniter;

[0017] c. The combustion process heats up the tubular heater located on the stove core body, vaporizing the liquid fuel inside the tubular heater;

[0018] d. The vaporized fuel is injected from the injector into the combustion chamber to keep the burner core burning.

[0019] Compared with the prior art, the present invention has the following advantages:

[0020] 1. This invention provides a tubular vaporization stove core for use in fuel stoves. It uses pre-burning of liquid fuel in the combustion chamber and uses the heat generated during the combustion process to heat the tubular heater, thereby vaporizing the liquid fuel in the tubular heater. This replaces the existing method of using electric heating to vaporize liquid fuel, solving the problem of dependence on electricity. Moreover, it has high heating efficiency, makes the structure simpler, more convenient to use, energy-saving, and helps to improve service life while reducing manufacturing costs.

Detailed Implementation Methods

[0026] To make the technical problems solved, the technical solutions, and the beneficial effects of this invention clearer, the invention will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the invention and are not intended to limit the invention.

[0027] This invention is achieved through the following technical solution:

[0028] like Figures 1 to 4 As shown, a tubular vaporization burner core for use in fuel stoves includes a burner core body 1 with a combustion chamber 101, a tubular heater 2 disposed on the burner core body 1, and an injector 3 disposed within the combustion chamber 101. One end of the tubular heater 2 is connected to an oil supply pipe, and the other end is connected to the injector 3 within the combustion chamber 101. The tubular heater 2 is disposed on the outer periphery of the burner core body 1 or on the inner wall of the combustion chamber 101 so that the burner core body 1 can heat the tubular heater 2 when it is burning. This invention provides a tubular vaporization burner core for use in fuel stoves. By pre-combusting liquid fuel in the combustion chamber and using the heat generated during the combustion process to heat the tubular heater, the liquid fuel in the tubular heater is vaporized. This replaces the existing method of using electric heating to vaporize liquid fuel, solving the problem of dependence on electricity. Moreover, it has high heating efficiency, a simpler structure, is more convenient to use, energy-saving, and helps to extend service life while reducing manufacturing costs.

[0029] Furthermore, the burner core body 1 is also provided with a return port 5 at the bottom. During the first ignition, fuel flows into the combustion chamber, the igniter ignites part of the fuel, and the excess fuel is recovered from the return hole through the return port. The excess fuel flows back to the storage container, saving fuel and avoiding excessive fuel leakage that could cause safety hazards.

[0030] In this design, the tubular heater 2 is coiled around the outer periphery of the stove core body 1 or the inner wall of the combustion chamber 101. This coiling arrangement ensures that the tubular heater 2 is in full contact with the inner or outer wall of the stove core body 1, allowing for rapid heating during the first combustion cycle, thus increasing heat transfer and vaporization speed. Furthermore, it replaces electric heating, eliminating the need for an electric heating element. This results in a simpler structure, greater ease of use, energy savings, extended service life, and reduced manufacturing costs.

[0031] As described above, the tubular heater 2 in this application is implemented in two ways: either on the outer wall or inside the cavity. For embodiment one, as... Figures 1 to 3 As shown, the tubular heater 2 is located on the outer periphery of the stove core body 1. This structure is relatively simple and easy to manufacture and install.

[0032] Furthermore, for better fit, the outer peripheral wall of the cooktop body 1 is provided with a spiral-shaped embedding groove 21. This allows the tubular heater portion to be embedded into the embedding groove 21, facilitating positioning and installation, and increasing the contact area between the tubular heater and the outer wall of the cooktop, thereby improving thermal efficiency.

[0033] For the tubular heater embodiment two, as follows Figure 4 As shown, the tubular heater 2 is located on the inner wall of the combustion chamber 101. Compared with Embodiment 1, this method places the tubular heater inside the combustion chamber, allowing direct heating during combustion, resulting in the highest thermal efficiency. Furthermore, the stove core body 1 has a through hole 102 penetrating its outer peripheral wall and connecting to the combustion chamber 101. One end of the tubular heater 2 passes through this through hole and connects to the external oil supply pipe.

[0034] Furthermore, in Embodiment 3 of the tubular heater, the tubular heater 2 can be wound around the outer wall of the stove core body 1, with one end penetrating into the combustion cavity through the through hole, and the inner end still set on the inner wall of the combustion cavity in a spiral winding manner, that is, the tubular heater 2 is wound around the inner and outer walls of the stove core body.

[0035] Furthermore, the combustion chamber 101 is also equipped with an igniter and a flame cap 13. Additionally, the tubular heater can utilize various pipe types, such as circular or square. In this design, one end of the tubular heater 2 is the mounting end connected to the injector, allowing connection to annular, direct-injection, or multi-hole atomizing injectors. The direct-injection injector mounting end is installed at the bottom of the stove core body 1, while the annular and multi-hole atomizing injectors are installed on the inner walls around the stove core body. The combustion chamber, located at the injector, is equipped with various flame cap types, including umbrella-shaped and conical.

[0036] In this design, the stove core body 1 has an outwardly turned edge 11 located above the combustion chamber 101, and the edge 11 has several ventilation holes 12. This satisfies the combustion requirements.

[0037] This application also provides a method for igniting the burner core of a fuel stove, comprising the following steps:

[0038] a. Liquid fuel is introduced into the combustion chamber 101 through the tubular heater 2;

[0039] b. The liquid fuel in the combustion chamber 101 is burned by an igniter;

[0040] c. The combustion process heats up the tubular heater 2 located on the stove core body 1, vaporizing the liquid fuel inside the tubular heater 2;

[0041] d. The vaporized fuel is injected from the injector into the combustion chamber 101 to keep the burner core burning.

[0042] It replaces the existing method of using electric heating to vaporize liquid fuel by pre-combusting liquid fuel in the combustion chamber and using the heat generated during the combustion process to heat the tubular heater. This solves the problem of dependence on electricity, and has high heating efficiency, making the structure simpler, easier to use, more energy-saving, and conducive to improving service life while reducing manufacturing costs.

[0043] The above description provides one or more embodiments in conjunction with specific content, and does not imply that the specific implementation of the present invention is limited to these descriptions. Any methods or structures that are similar to or identical to those of the present invention, or any technical deductions or substitutions made based on the concept of the present invention, should be considered within the scope of protection of the present invention.
