Description

Technical Field

[0001] This utility model belongs to the field of fuel stove technology, specifically relating to an atomizing fuel stove structure. Background Technology

[0002] An oil-fired stove is a type of stove used in hotels, restaurants, and other similar establishments. The flame size is typically adjusted by regulating the amount of fuel entering the stove. However, because oil-fired stoves are generally open at the top, they often cannot provide enough air for combustion, resulting in incomplete combustion and affecting efficiency. For example, as shown in CN202420324007.8, while multiple flame guides and flame control components can control the amount of fuel burned, this stove also suffers from insufficient air-fuel mixing and inadequate air intake, further impacting combustion efficiency, operational stability, and reliability, making it difficult to meet market demands.

[0034] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0035] Example

[0036] See Figures 1 to 4 As shown, an atomizing fuel stove structure includes a bottom shell 1 and a stove body disposed within the bottom shell. The stove body includes a water receiving tray 2, a guide pipe 3, an ignition needle 4, an igniter 5, a blower 6, an atomizer 7, a fuel pump 8, and a controller 9. In this embodiment, the controller, blower, atomizer, ignition needle, and fuel pump are all conventional structures of the prior art, simply used for practical purposes. The corresponding models can be selected according to needs, as long as the corresponding purpose is achieved, so they are not described in detail. The atomizer is an ultrasonic atomizer or a conventional atomizer. The bottom shell is a stainless steel structure. It is powered by an external battery pack, which facilitates transportation and packaging.

[0037] In this embodiment, the bottom surface of the water receiving tray is provided with a jet nozzle 10; in actual application, the top surface of the water receiving tray is provided with a flame spreader 11. The flame spreader is mainly used to disperse the sprayed oil mist, which helps to increase the contact area with air, thereby improving the completeness of combustion during ignition.

[0038] In this embodiment, the ignition needle is fixed to the edge of the jet nozzle and connected to the igniter via a conductive wire for fuel ignition; the ignition needle generates a high voltage and achieves ignition when the controller is turned on, which is a conventional structure in the prior art and is simply applied.

[0039] like Figure 1 , Figure 2 , Figure 3As shown, in this embodiment, the guide pipe is a sealed structure with an air outlet 12 at one end and a blower connection port 13 and an atomizing mounting hole 14 at the other end. The atomizing mounting hole is located between the blower connection port and the air outlet. The sealed structure of the guide pipe prevents fuel leakage, improving safety. Furthermore, the blower ensures that all oil mist is ejected from the air outlet, increasing the oil mist ejection pressure and facilitating mixing of air and oil mist within the guide pipe. The atomizing mounting hole, located between the blower connection port and the air outlet, allows the blower's airflow to direct the oil mist towards the air outlet. The size of the air outlet can be customized as needed, specifically, its diameter should be the same as the nozzle diameter. The distance between the atomizing mounting hole and the blower connection port can be adjusted as needed; generally, they should be close together. A greater distance between the atomizing mounting hole and the air outlet is better, as it promotes thorough mixing of air and oil mist. Furthermore, its blower connection port can be directly set at the end, or it can be set on the side wall near the end.

[0040] During assembly, the guide pipe is positioned on the bottom surface of the water receiving tray, and its air outlet is connected to the jet nozzle. A baffle 25 is installed inside the jet nozzle. The blower's air outlet is connected to the blower connection port. The atomizer is fixed at the fuel atomization mounting hole, and its spray nozzle extends into the guide pipe. The fuel pump's inlet pipe is connected to an external fuel tank, and its outlet pipe is connected to the atomizer. The controller is connected to the ignition needle, atomizer, blower, and fuel pump via wires. In this embodiment, there are two fuel pumps, and the outlets of both pumps are connected to the liquid inlet of the atomizer. This ensures the effectiveness and stability of fuel injection.

[0041] High-flash-point vegetable oils and mineral oils can be used in external oil storage tanks, which expands their applicability.

[0042] like Figure 2 , Figure 3 As shown in this embodiment, the guide tube is a one-piece molded structure, and the oil guiding chamber inside the guide tube is a figure-eight shape with one end larger than the other. The air outlet is located at the narrow end of the oil guiding chamber, the blower connection port is located at the wide end of the oil guiding chamber, and the fuel atomizer mounting hole is located on the top wall of the guide tube and close to the blower. The airflow from the blower blows the atomized oil mist from the atomizer toward the air outlet and sprays it outward from the air outlet. Because the oil guiding chamber is figure-eight shaped and the air outlet is located at the narrow end, the injection pressure at the air outlet can be increased when the blower blows air, improving the effectiveness and stability of the injection. Furthermore, the width of the narrow end of the figure-eight shape can be set as needed, specifically, the diameter of the narrow end can be the same as that of the oil outlet.

[0043] In this embodiment, to improve the sealing performance of the guide pipe, an oil drain pipe 23 and a return oil pump 24 connected to the oil drain pipe are provided on the bottom wall of the guide pipe. This allows for the removal of deposited oil and its return to an external oil storage tank.

[0044] like Figure 1 , Figure 2 and Figure 3 As shown, in this embodiment, a wind guide window 15 is provided on the side wall of the bottom shell. This ensures the effectiveness of the blower's air intake. In actual application, there is a mesh screen between the blower and the oil pump.

[0045] like Figures 1-3 As shown, the controller is equipped with a rotary switch 16 and an indicator light 17.

[0046] To ensure effective load-bearing capacity, the top surface of the water receiving tray is equipped with several pot support racks 18. This ensures sufficient combustion space on the top surface of the water receiving tray and increases the overall load-bearing capacity of the tray. The number of pot support racks is three or four.

[0047] In practical applications, the top surface of the bottom shell is provided with a glass panel 19, the glass panel is provided with a through hole 20, the water receiving tray is located in the through hole, and the rotary switch extends out of the top surface of the glass panel.

[0048] Meanwhile, the bottom surface of the base shell is provided with foot pads 21 and strip-shaped slots 22; the oil inlet pipe of the oil pump extends out of the base shell from the strip-shaped slots. The width of the strip-shaped slots can be set as needed.

[0049] In practical applications, the deflector is equipped with several inclined deflector plates 26, and guide slots are provided between adjacent inclined deflector plates; the several inclined deflector plates are located on the same ring; the oil and gas in the guide pipe are blown out by the deflector and form a vortex-shaped airflow in the water receiving tray. The inclination angle of the inclined deflector plates is 15°-45°.

[0050] A baffle is fixed in the middle of the bottom wall of the water receiving tray. The baffle is equipped with several inclined baffles, which, together with the air inlet and fuel atomization mounting hole on the guide pipe, cause the oil and gas in the guide pipe to form a vortex-shaped airflow in the water receiving tray after being blown out by the baffle. The baffle helps to disperse the oil and gas, increases the contact area with air, improves the completeness and efficiency of combustion, and the baffle's turbulent flow and premixing create a turbulent state, which helps to improve the reliability and efficiency of combustion and has strong applicability.

[0051] Its working principle is briefly described as follows:

[0052] When the controller starts, the oil pump pumps oil from the external oil tank into the atomizer, where it is atomized and sprayed into the guide tube. At the same time, the blower starts, sending air into the guide tube. The airflow carries the atomized oil mist towards the air outlet. During this blowing process, the air and oil mist mix. Because the oil guide chamber is shaped like a figure eight with one end larger than the other, the airflow column from the blower gradually decreases, increasing the pressure of the oil mist sprayed from the air outlet. When the ignition needle ignites, the oil mist is ignited, achieving combustion. The liquefied and deposited oil in the guide tube is pumped back to the external oil tank through the drain pipe and the return oil pump.

[0053] This invention has several positive effects: Its structure is rationally designed, incorporating a guide tube, ignition needle, blower, atomizer, and fuel pump. The atomizer atomizes the fuel from the fuel pump, and the blower mixes the atomized fuel thoroughly with air before blowing it out through the nozzle of the water tray. The ignition needle then ignites the fuel, improving combustion completeness and efficiency. Furthermore, the blower's airflow can be adjusted to control the flame size, enhancing control effectiveness. The overall structure is simple, reducing costs. The guide tube, in conjunction with the blower, is less prone to clogging. It can use high-flash-point vegetable and mineral oils. The baffle promotes fuel-air dispersion, increasing the contact area with air and improving combustion completeness and efficiency. The baffle's premixing and turbulence enhances combustion reliability and efficiency, broadening its applicability. It is stable, reliable, and highly adaptable.

[0054] The standard parts used in this embodiment can be purchased directly from the market, while the non-standard structural parts described in the instruction manual can be processed without any doubt based on existing technical common sense. At the same time, the connection methods of each component adopt mature conventional methods in the existing technology, and the machinery, parts and equipment all adopt conventional models in the existing technology, so they will not be described in detail here.

[0055] Obviously, the above embodiments of this utility model are merely examples for clearly illustrating this utility model, and are not intended to limit the implementation of this utility model. Those skilled in the art can make other variations or modifications based on the above description. It is neither necessary nor possible to exhaustively list all embodiments here. However, these obvious variations or modifications derived from the essential spirit of this utility model still fall within the protection scope of this utility model.
