Technical Field

[0001] The present invention relates to the technical field of air heaters, and in particular to a fuel-fired air heater with an air guiding function. Background Art

[0002] Among various modern heating methods, air heating is relatively comfortable, and heaters are the most common air heating method. Heaters include fuel heaters, electric heaters and gas heaters. Among them, the main purpose of fuel heaters is to heat industrial or commercial places, and can also be used to dry products. The working principle of a fuel heater is to pump fuel from the fuel tank through an oil pump, and the fuel is sprayed out after being atomized through the oil nozzle, and then burns in the combustion barrel to generate heat. However, the oil pumps used in current fuel heaters have the disadvantages of high noise, unstable pressure and short service life, which makes the heating effect of fuel heaters poor. In addition, existing heaters generally use turbine motors to supply air and oxygen to the combustion barrel, so that the fuel can have sufficient oxygen for full combustion. However, the use of turbine motors for oxygen supply not only increases production costs, but also increases the difficulty of assembly. Summary of the Invention

DETAILED DESCRIPTION

[0029] The technical solution of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the embodiments described are only some embodiments of the present invention, not all embodiments. All other embodiments obtained by ordinary technicians in this field based on the embodiments of the present invention without making any creative efforts shall fall within the scope of protection of the present invention.

[0030] Example 1

[0031] The present invention provides a fuel heater with air guide function, such as Figure 1 and Figure 2 As shown, it includes a fuel tank 1, an upper cover plate 3 and a lower cover plate 2, which are buckled together to form a receiving cavity, which is located at the upper part of the fuel tank 1. Figure 1 and 2 As shown, the accommodating chamber is equipped with a combustion tube 5, a burner 6, an air guide assembly 9, an electromagnetic pump 8 and a fan assembly 7. The burner 6 is installed at the left end of the combustion tube 5. The left end of the combustion tube 5 is provided with a plurality of ventilation holes 51, which are evenly arranged in a ring shape. Figure 3 and Figure 3 As shown, the burner 6 is provided with a flame stabilizing disk 61, and the air guide assembly 9 is composed of a plurality of air guide blades 91, the number of which corresponds to the air guide ventilation holes 51. The air guide blades 91 are mounted on the fins of the flame stabilizing disk 61, and the air guide surface of each air guide blade 91 is located on one side of the corresponding ventilation hole 51, so that the air guide surface of the air guide blade 91 can guide more air flow to enter the ventilation hole 51 smoothly, ensuring that there is sufficient oxygen in the combustion tube 5 to ensure the full combustion of the fuel, thereby improving the energy efficiency ratio of the heater. In addition, since the present invention is provided with an air guide assembly 9, the use of a turbine motor for air supply in the existing heater is eliminated, which significantly reduces the cost of the heater of the present invention and simplifies the assembly process.

[0032] like Figure 1 As shown, the fuel injection port of the burner 6 is connected to the cavity of the combustion tube 5, and the fuel injected from the fuel injection port of the burner 6 is burned in the combustion tube 5. The fuel inlet of the burner 5 is directly connected to the oil outlet of the electromagnetic pump 8, eliminating the need for connecting pipes and reducing the risk of oil leakage. The fuel inlet of the electromagnetic pump 8 is connected to the fuel tank 1 through the oil pipe 81 through the lower cover plate 2. The flow direction of the fuel is as follows: Figure 1 As shown by the arrow in the middle, by installing an electromagnetic pump 8 within this fuel heater to deliver fuel to the burner 6, the electromagnetic pump 8 operates at a stable pressure, ensuring a steady flow of fuel to the burner 6. This allows the fuel entering the combustion chamber 5 to be fully atomized and burned within the combustion chamber 5, thereby improving the heating effect of the fuel heater. Furthermore, the electromagnetic pump 8 is quiet, significantly reducing the noise level of the fuel heater and thereby extending its service life. In this embodiment, the electromagnetic pump 8 is a conventional pump body, and its specific structure will not be described in detail.

[0033] like Figure 2 and Figure 3 As shown, multiple air guide vanes 91 are mounted on the flame stabilizing plate 61, with the air guide surface of each air guide vane 91 located on one side of the corresponding ventilation hole 51. This allows the air guide surface of the air guide vane 91 to guide more airflow smoothly into the ventilation hole 51, ensuring sufficient oxygen within the combustion tube 5 to ensure sufficient combustion of the fuel. The air guide vanes 91 serve to gather and guide air, replacing the turbo blower used in the prior art. This is not only more cost-effective but also easier to assemble. Of course, to further simplify the assembly process, the air guide vanes 91 can be integrally formed with the flame stabilizing plate 61.

[0034] like Figure 1 and Figure 2 As shown, the fan assembly 7 includes fan blades 71 and a motor 72 for driving the fan blades 71 to rotate. The fan blades 71 are set in the direction of the burner 6. The wind blown out by the motor 72 driving the fan blades 71 to rotate is blown toward the electromagnetic pump 8 and the air guide plate 91. The air guide plate 91 gathers the wind and guides it to flow quickly into the ventilation hole 51.

[0035] like Figure 1 and Figure 2 As shown, an oil pipe regulating device 10 is provided at the bottom of the lower cover plate 2. The oil pipe 81 passes through the lower cover plate 2 and the oil pipe regulating device 10 in sequence and is connected to the fuel tank 101. The oil pipe regulating device 10 is provided with a knob 101 for regulating the fuel flow in the oil pipe 81. The fuel heater is turned off, on or off or regulates the fuel flow in the oil pipe 81 by rotating the knob 101.

[0036] like Figure 1 and Figure 2 As shown, an air inlet is provided at one end of the accommodating chamber near the fan assembly 7, and a filter 11 is installed at the air inlet. When the fan assembly 7 is running, the filter 11 can block some impurities in the air from entering the accommodating chamber, ensuring the safety and cleanliness of various components in the accommodating chamber.

[0037] like Figure 1 and Figure 2 As shown, the fuel heater includes a pipe rack 4 with an accommodating space. The fuel tank 1, the upper cover plate 3 and the lower cover plate 2 are all installed in the accommodating space of the pipe rack 4. The pipe rack 4 can well fix the fuel tank 1, the upper cover plate 3 and the lower cover plate 2; the bottom of the pipe rack 4 is provided with a roller 41 to facilitate the movement of the fuel heater.

[0038] Example 2

[0039] The same technical features of this embodiment as those of Example 1 will not be described in detail. The difference between this embodiment and Example 1 is that: Figure 4 As shown, the air guide assembly 9 is a wind guide plate 92 fixed to the inner wall of the accommodating chamber, located near the air outlet surface of the fan blades. The wind guide plate 92 is composed of two straight wind guide bars arranged in parallel with each other. The rotation axis of the fan motor is located between the two straight wind guide bars. This ensures that the airflow blown out by the fan blades is concentrated and guided by the wind guide plate 92, and then blown towards the ventilation hole 51 with greater wind pressure, allowing more airflow to enter the combustion tube 5.

[0040] Example 3

[0041] The same technical features of this embodiment as those of Example 1 will not be described in detail. The difference between this embodiment and Example 1 is that: Figure 5 As shown, the air guide assembly 9 includes not only the air guide vanes 91 of Example 1, but also an air guide plate 92 fixed to the inner wall of the accommodating chamber, and the air guide plate 92 is close to the air outlet surface of the fan blades. The air guide plate 92 is composed of two straight air guide strips arranged in parallel with each other, and the rotation axis of the fan motor is located between the two straight air guide strips. This ensures that the airflow blown out by the fan blades is collected and guided by the air guide plate 92, and then blown to the air guide vanes 91 with a higher wind pressure. The airflow is further guided by the air guide vanes 91, allowing more airflow to enter the ventilation hole 51 more smoothly and quickly, ensuring sufficient oxygen supply in the combustion tube 5.

[0042] Example 4

[0043] The same technical features of this embodiment as those of Example 2 will not be described in detail. The difference between this embodiment and Example 2 is that: Figure 6 As shown, each straight air guide has a notch in the middle, dividing the two straight air guides into four shorter air guides. The notch corresponds to the rotation axis of the fan motor, and the shorter air guides correspond to the ventilation holes 51. This allows the airflow from the fan blades to be gathered and guided by the air guide plate 92 and then blown toward the ventilation holes 51 with greater pressure, ensuring that more airflow enters the combustion tube 5.

[0044] Example 5

[0045] The same technical features as those in Example 3 will not be described in detail. The difference between this embodiment and Example 4 is that: Figure 7 As shown, each straight air guide has a notch in the middle, dividing the two straight air guides into four shorter air guides. The notch corresponds to the rotation axis of the fan motor, and the shorter air guides correspond to the ventilation holes 51. This allows the airflow from the fan blades to be gathered and guided by the air guide plate 92, and then blown to the air guide vanes 91 with greater pressure. The airflow is then further guided by the air guide vanes 91, allowing more airflow to enter the ventilation holes 51 more smoothly and quickly, ensuring sufficient oxygen supply to the combustion tube 5.

[0046] Example 6

[0047] The same technical features of this embodiment as those of Example 1 will not be described in detail. The difference between this embodiment and Example 1 is that: Figure 8 As shown, the air guide assembly is a guide plate 92 fixed to the inner wall of the accommodating chamber, located near the air outlet surface of the fan blades. The guide plate 92 is composed of two straight air guide bars arranged in a cross pattern. The rotation axis of the fan motor is located at the intersection of the two straight air guide bars. This ensures that the airflow blown out by the fan blades is concentrated and guided by the guide plate 92, and then blown towards the ventilation hole 51 with greater wind pressure, allowing more airflow to enter the combustion tube 5.

[0048] Example 7

[0049] The same technical features of this embodiment as those of Example 1 will not be described in detail. The difference between this embodiment and Example 1 is that: Figure 9As shown, the air guide assembly 9 includes not only the air guide vanes 91 of Example 1, but also an air guide plate 92 fixed to the inner wall of the accommodating chamber, and the air guide plate 92 is close to the air outlet surface of the fan blades. The air guide plate 92 is composed of two straight air guide strips arranged in a cross pattern, and the rotation axis of the fan motor is located at the cross intersection of the two straight air guide strips. This ensures that the airflow blown out by the fan blades can be gathered and guided by the air guide plate 92 and then blown to the air guide vanes 91 with a higher wind pressure. The airflow is then guided again by the air guide vanes 91, allowing more airflow to enter the ventilation holes 51 more smoothly and quickly, ensuring sufficient oxygen supply in the combustion tube 5.

[0050] Example 8

[0051] The same technical features of this embodiment as those of Example 1 will not be described in detail. The difference between this embodiment and Example 1 is that: Figure 10 As shown, the air guide assembly 9 is a wind guide plate 92 fixed to the inner wall of the accommodating chamber, and the wind guide plate 92 is close to the air outlet surface of the fan blades. The wind guide plate 92 is composed of two cross-shaped S-shaped wind guide strips. The rotation axis of the fan motor is located at the intersection of the two straight wind guide strips. The curvature of the S-shaped wind guide strip is opposite to the rotation direction of the fan blades. This ensures that the airflow blown out by the fan blades can be concentrated and guided by the S-shaped wind guide strips and then blown towards the ventilation hole 51 with greater wind pressure, allowing more airflow to enter the combustion tube 5.

[0052] Example 9

[0053] The same technical features of this embodiment as those of Example 1 will not be described in detail. The difference between this embodiment and Example 1 is that: Figure 11 As shown, the air guide assembly 9 not only includes the air guide vanes 91 in Example 1, but also includes an air guide plate 92 fixed to the inner wall of the accommodating cavity, and the air guide plate 92 is close to the air outlet surface of the fan blades. The air guide plate 92 is composed of two S-shaped air guide strips arranged crosswise, and the rotation axis of the fan motor is located at the cross intersection of the two straight air guide strips. The curvature of the S-shaped air guide strip is opposite to the rotation direction of the fan blades, ensuring that the airflow blown out by the fan blades can be gathered and guided by the S-shaped air guide strips, and then blown to the air guide vanes 91 with a greater wind pressure. The airflow is guided again by the air guide vanes 91, so that more airflow enters the ventilation hole 51 more smoothly and quickly, ensuring sufficient oxygen supply in the combustion tube 5.

[0054] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention, rather than to limit the scope of protection of the present invention. Although the present invention has been described in detail with reference to the preferred embodiments, those skilled in the art should understand that the technical solutions of the present invention may be modified or replaced by equivalents without departing from the essence and scope of the technical solutions of the present invention.
