Description

Technical Field

[0001] This utility model relates to the technical field of heaters, and in particular to a heater having a hollow ignition plate and inner and outer ejector tubes. Background Technology

[0002] In existing gas heater technology, the burner head generally adopts a two-piece ignition plate structure. This design results in a large furnace cavity space, a long mixing path between gas and air, and a lack of effective guidance, making it difficult to precisely control the mixing ratio. During combustion, uneven mixing can easily lead to localized rich or lean combustion, resulting in low combustion efficiency. At the same time, the flame stability is poor, making it highly susceptible to external wind interference, which can cause safety hazards such as backfire or flameout. Utility Model Content

[0003] The purpose of this invention is to provide a heater with a hollow ignition plate and inner and outer ejector tubes to address the deficiencies in the existing technology. This design can significantly reduce the combustion chamber space of the gas heater burner and optimize the gas and air mixing path, thereby improving the accuracy of the mixing ratio control, increasing combustion efficiency, enhancing external flame stability, significantly improving wind resistance, and reducing the risk of backfire.

[0004] To achieve the above objectives, the technical solution adopted by this utility model is as follows: It includes a heater combustion section, and a hollow ignition plate is provided inside the heater combustion section; the hollow ignition plate consists of a burner head cover, a burner head bottom cover, an inner ejector tube, and an outer ejector tube; the inner ejector tube is a hollow pipe located inside the outer ejector tube, and the burner head cover and the burner head bottom cover are located above the inner and outer ejector tubes; both the burner head cover and the burner head bottom cover have a hollow structure in the middle; the inner ejector tube is fixedly connected to the burner head cover, and the outer ejector tube is fixedly connected to the burner head bottom cover; the burner head cover and the burner head bottom cover are fixedly connected to form a hollow burner head assembly, and the gas passes through the gap between the inner and outer ejector tubes to reach the burner head assembly.

[0005] Furthermore, the shape of the opening on the combustion head cover is consistent with the shape of the inner ejector tube.

[0006] Furthermore, the shape of the opening of the lower cover of the combustion head is consistent with the shape of the external ejector tube.

[0007] Furthermore, the hollow ignition plate is also provided with a base, the external ejector tube is fixed on the base, and the hollow ignition plate is fixed on the burner part of the heater through the base.

[0008] Furthermore, the heater combustion unit is fixed above the gas cylinder chamber via a fixing pipe.

[0009] Furthermore, a controller is also provided on the combustion section of the heater, and the controller is located below the hollow ignition plate.

[0010] Furthermore, a heater base is also provided below the gas cylinder chamber.

[0011] The gas heater employs a combustion chamber and a hollow ignition plate within it. The hollow ignition plate comprises a burner head cover, a burner head bottom cover, an inner ejector tube, and an outer ejector tube. The inner ejector tube is a hollow conduit within the outer ejector tube. The burner head cover and the burner head bottom cover are positioned above the inner and outer ejector tubes, respectively. Both the burner head cover and the burner head bottom cover have a hollow structure in the middle. The inner ejector tube is fixedly connected to the burner head cover, and the outer ejector tube is fixedly connected to the burner head bottom cover. This fixed connection forms a hollow burner head assembly, significantly reducing the combustion chamber space of the gas heater burner head and optimizing the gas-air mixing path. This improves the accuracy of the mixing ratio control, increases combustion efficiency, enhances external flame stability, significantly improves wind resistance, and reduces the risk of backfire.

[0020] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0021] In the description of this utility model, it should be noted that the orientation or positional relationship indicated by terms such as "center", "up", "down", "left", "right", "vertical", "horizontal", "inner", and "outer" are based on the orientation or positional relationship shown in the accompanying drawings. They are only for the convenience of describing this utility model and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this utility model.

[0022] A heater with a hollow ignition plate and inner and outer ejector tubes, such as Figures 1-5 As shown, the device includes a heater combustion section 1 and a hollow ignition plate 2 disposed within the heater combustion section 1. The hollow ignition plate 2 consists of a burner head cover 3, a burner head lower cover 4, an inner ejector tube 5, and an outer ejector tube 6. The inner ejector tube 5 is disposed within the outer ejector tube 6 and is a hollow pipe. The burner head cover 3 and the burner head lower cover 4 are disposed above the inner ejector tube 5 and the outer ejector tube 6. Both the burner head cover 3 and the burner head lower cover 4 have a hollow structure in the middle. The inner ejector tube 5 is fixedly connected to the burner head cover 3, and the outer ejector tube 6 is fixedly connected to the burner head lower cover 4. The burner head cover 3 and the burner head lower cover 4 are fixedly connected to form a hollow burner head assembly. Gas gas reaches the burner head assembly through the gap between the inner ejector tube 5 and the outer ejector tube 6.

[0023] Specifically, a novel burner head assembly structure is formed through the nested structure of the inner ejector tube 5 within the outer ejector tube 6, and the hollow design of the burner head cover 3 and the burner head lower cover 4. Gas flows through the gap between the inner ejector tube 5 and the outer ejector tube 6 to reach the burner head assembly, reducing the furnace cavity space and allowing for better control of the air-gas mixing ratio. The smaller furnace cavity space also makes the external flame more stable. The reduced furnace cavity volume makes the air-gas mixing area more concentrated, and the mixing process is more controllable, effectively solving the problem of difficult precise control of the mixing ratio caused by the large furnace cavity space in traditional structures. This significantly enhances the heater's wind resistance and reduces the risk of backfire. Improved flame stability makes the combustion process safer and more reliable, and also extends the heater's lifespan.

[0024] As a preferred embodiment of the above, such as Figures 1-5 As shown, the shape of the opening of the combustion head cover 3 is consistent with the shape of the inner ejector tube 5.

[0025] Specifically, by ensuring that the opening shape of the burner head cover 3 matches the shape of the inner ejector tube 5, the connection structure between the inner ejector tube 5 and the burner head cover 3 is optimized. This allows the gas to flow more smoothly into the combustion area above the burner head cover 3 after exiting the inner ejector tube 5, reducing resistance during gas flow, reducing energy loss during gas flow, improving gas flow efficiency, enabling the gas to mix with air more quickly, and further ensuring the adaptability of the burner head assembly.

[0026] As a preferred embodiment of the above, such as Figures 1-5 As shown, the opening shape of the lower cover 4 of the combustion head is consistent with the shape of the external ejector tube 6.

[0027] Specifically, the seamless structure formed at the connection between the outer ejector tube 6 and the lower cover 4 of the burner head significantly reduces the risk of gas leakage and enhances the overall structural stability of the burner head assembly. This is suitable for situations where the outer ejector tube needs to withstand high gas pressure, improving the durability of the equipment. At the same time, the uniform shape reduces the diffusion loss of gas at the outlet of the outer ejector tube, allowing the mixed gas to enter the outer combustion zone with a more stable flow rate and direction, optimizing the combustion efficiency of the outer flame. Especially under external interference such as strong winds, the anti-disturbance ability of the outer flame is significantly enhanced, further reducing the risk of backfire.

[0028] As a preferred embodiment of the above, such as Figures 1-5 As shown, the hollow ignition plate 2 is also provided with a base 7, the external ejector tube 6 is fixed on the base 7, and the hollow ignition plate 2 is fixed on the heater combustion section 1 through the base 7.

[0029] Specifically, the external injector tube 6 and the hollow ignition plate 2 are integrated through the base 7 and fixed to the burner section 1, realizing a modular design of the burner head assembly. The base 7, as the core connector, integrates the external injector tube 6, the hollow ignition plate 2, and the burner section 1 into a single functional module, simplifying the installation process. Users only need to fix the base 7 to complete the assembly of the entire burner head assembly, significantly reducing installation complexity. At the same time, the base 7, as a standardized interface, provides convenience for subsequent maintenance and reduces equipment downtime.

[0030] As a preferred embodiment of the above, such as Figures 1-5 As shown, the heater combustion section 1 is fixed above the gas cylinder chamber 10 by a fixing pipe 9.

[0031] Specifically, the vertical layout significantly reduces the overall footprint of the equipment, making it particularly suitable for space-constrained scenarios. At the same time, the fixed pipe 9, as a rigid connection, reduces the redundant length of the gas pipeline and lowers the risk of gas leakage.

[0032] As a preferred embodiment of the above, such as Figures 1-5 As shown, a controller 11 is also provided on the combustion section 1 of the heater, and the controller 11 is located below the hollow ignition plate 2.

[0033] As a preferred embodiment of the above, such as Figures 1-5 As shown, a heater base 8 is also provided below the gas cylinder chamber 10.

[0034] Specifically, the controller 11 is located below the hollow ignition plate 2 to control the opening and closing of the heater combustion section 1. The area below the hollow ignition plate 2 is usually at a lower temperature, and the controller 11 is far away from the high-temperature combustion area, reducing the interference of heat radiation on electronic components and significantly improving the stability and service life of the controller. At the same time, the appropriate height also makes it easy to adjust parameters such as power and temperature. The heater base 8 can also improve the stability of the device on smooth ground by increasing the contact area or integrating anti-slip pads, reducing the risk of accidental tipping.

[0035] The foregoing has shown and described the basic principles, main features, and advantages of this utility model. Those skilled in the art should understand that this utility model is not limited to the above embodiments. The embodiments and descriptions in the specification are merely illustrative of the principles of this utility model. Various changes and modifications can be made to this utility model without departing from its spirit and scope, and all such changes and modifications fall within the scope of the claimed utility model. The scope of protection of this utility model is defined by the appended claims and their equivalents.
