Description

Technical Field

[0001] This invention relates to the field of hot air balloon equipment technology, and in particular to a novel hot air balloon burner. Background Technology

[0002] The burner is the core power component for hot air balloons to achieve stable ascent, descent, and safe flight. Its operational reliability, environmental adaptability, and ease of operation are directly related to flight safety. As hot air balloon flight scenarios become increasingly diverse, existing burners have gradually revealed many shortcomings in practical applications, making it difficult to meet the flight requirements in complex scenarios, and thus there is room for improvement.

[0003] In the emergency ignition phase, the emergency fire valve of the existing hot air balloon burner only has a simple on / off function and lacks a fine-tuning structure for opening. When the pilot flame valve becomes blocked or malfunctions, or the igniter is damaged and cannot ignite normally, the emergency fire valve cannot adjust the fuel output and cannot form a stable small ignition source to replace the pilot flame to ignite the main flame. This may cause the burner to stop, thereby affecting the flight safety of the hot air balloon.

[0004] In terms of main flame nozzle design, existing burners mostly adopt a one-piece fixed structure for the main flame nozzle, with fixed structural parameters that cannot be flexibly adjusted according to ambient temperature. In extreme environments with high or extremely low temperatures, one-piece nozzles are prone to problems such as unstable combustion, poor fuel supply, or even blockage, which not only reduces combustion efficiency but also affects the flight stability of the hot air balloon.

[0005] In terms of ease of operation and comfort, the pressure gauges on existing burner valve bodies are all vertically mounted, which does not match the pilot's line of sight while operating from inside the basket. When checking fuel pressure data, the pilot needs to deliberately lean forward to adjust their line of sight, which is inconvenient and easily distracts them. Long-term operation will also increase fatigue, which does not conform to the ergonomic design concept.

[0006] In summary, existing hot air balloon burners have significant shortcomings in terms of emergency ignition reliability, extreme temperature adaptability, and ergonomics, failing to fully meet the safety and convenience requirements of actual flights. Therefore, developing a new type of hot air balloon burner that can solve the above problems has become a technical problem that urgently needs to be solved by those skilled in the art. Summary of the Invention

[0007] The technical problem to be solved by this invention is to overcome the shortcomings of existing hot air balloon burners in terms of emergency ignition reliability, extreme temperature adaptability, and ergonomics, and to provide a burner that meets the actual needs of flight safety and convenience.

[0008] The technical solution adopted by this invention to solve its technical problem is as follows: a novel hot air balloon burner, comprising a bracket, two combustion units, and a reversing assembly connecting the two combustion units. Each combustion unit includes a protective cover and a valve body installed at the bottom of the protective cover. The valve body is equipped with a main fire valve, a pilot light valve, and an emergency fire valve. The main fire valve is connected to a multi-way serpentine coil, the end of which communicates with a nozzle disc. The nozzle disc is equipped with multiple main fire nozzles. The pilot light valve is connected to the pilot light nozzle, which is connected to an electronic igniter. The emergency fire valve is connected to an emergency fire nozzle, and the emergency fire valve is equipped with an operable fine-tuning component.

[0009] Each combustion unit's pilot light valve, main fire valve, and emergency fire valve are connected to the same fuel cylinder via pipelines, and the valve body is equipped with a pressure gauge.

[0010] Furthermore, the operable fine-tuning component includes an adjustment knob, a threaded sleeve, and a valve stem. The adjustment knob is fitted over the threaded sleeve and is driven by the threaded sleeve through a prism. The threaded sleeve is threadedly connected to the valve stem, and the valve stem is coaxially and integrally fixedly connected to the valve core.

[0011] Furthermore, rotating the adjustment knob causes the threaded sleeve to rotate, which in turn causes the valve stem and valve core to move linearly. The relative displacement between the valve core and the valve seat determines the valve opening, thereby enabling fine-tuning of the fuel flow.

[0012] Furthermore, the inner wall of the threaded sleeve and the outer wall of the valve stem are respectively provided with matching threads to realize the relative movement between the two.

[0013] Furthermore, the main fire nozzle includes a fixed nozzle and an adjustable nozzle, wherein the adjustable nozzle is detachably installed in the adjustable nozzle orifice.

[0014] Furthermore, the flow diameter of the adjustable nozzle is larger than that of a conventional fixed nozzle.

[0015] Furthermore, the number of fixed nozzles is set to 33, and the number of adjustable nozzles is set to 3.

[0016] Furthermore, the pressure gauge is arranged at an angle to the valve body plane, making it easier for the pilot to view.

[0017] The novel hot air balloon burner of the present invention has the following advantages:

[0018] 1. The emergency fire valve is equipped with an operable fine-tuning component that enables precise adjustment of fuel flow. In the event of a malfunction of the pilot fire valve or pilot igniter, a stable small fire source can be formed by igniting the main fire with the pilot's own igniter, thus preventing burner shutdown and significantly improving flight safety.

[0019] 2. The nozzle disc uses a combination of fixed and adjustable nozzles. The adjustable nozzles offer greater freedom of choice and can flexibly adjust the fuel flow according to the ambient temperature, effectively avoiding unstable combustion, fuel flow problems, and blockages under high or low temperature conditions, thereby improving combustion efficiency and flight stability.

[0020] 3. The pressure gauge is angled to the valve body, matching the pilot's line of sight, allowing for clear viewing without bending over, reducing operator fatigue and distraction, and improving ease of operation and safety. Attached Figure Description

[0029] The present invention will now be described in further detail with reference to the accompanying drawings. These drawings are simplified schematic diagrams, illustrating only the basic structure of the invention, and therefore only show the components relevant to the invention.

[0030] The novel hot air balloon burner of this invention mainly consists of a bracket 1, two sets of combustion units 2, and a reversing assembly 3 connecting the two. The bracket 1 is a high-strength stainless steel frame with lifting rings at its four corners for connection to the hot air balloon basket, providing stable support for the burner. The two sets of combustion units 2 are symmetrically arranged on the bracket 1, and their angles are adjustable through the reversing assembly 3 to adapt to the flame direction requirements under different flight conditions.

[0031] Each combustion unit 2 includes a protective shield 21, a valve body 27, and a multi-way serpentine coil. The protective shield 21 features a perforated design to guide airflow into the combustion zone, improving combustion efficiency and flame stability. The valve body 27 integrates a main fire valve 24, a pilot fire valve 23, an emergency fire valve 22, and a pressure gauge 25. The pressure gauge 25 is angled relative to the plane of the valve body 27 for easy monitoring of fuel pressure by the pilot.

[0032] The main fire valve 24 connects to a multi-way serpentine coil, with each coil's end connected to a nozzle disc. The nozzle disc is equipped with 33 fixed nozzles 28 and 3 adjustable nozzles (installed within adjustable nozzle orifices 29). The adjustable nozzles have a larger flow diameter than the fixed nozzles and can be replaced according to ambient temperature. The adjustable nozzles are threaded for easy and quick replacement and cleaning, reducing maintenance costs and difficulty.

[0033] In high-temperature environments, air density decreases and oxygen content becomes relatively insufficient, which can easily lead to incomplete combustion and reduced heating efficiency. In such cases, a nozzle with a larger flow diameter can be installed on the adjustable nozzle orifice to appropriately adjust the main fuel supply, thereby improving combustion stability and thermal efficiency and preventing unstable combustion and insufficient power due to high temperatures.

[0034] In low-temperature or frigid environments, fuel viscosity increases and flowability decreases, making pipelines and nozzles prone to poor gas supply, reduced atomization, and even localized blockages. By replacing the nozzles with adjustable nozzles with larger flow diameters, the throttling resistance of the fuel at the nozzle is reduced, ensuring stable fuel supply and uniform injection under low-temperature conditions. This maintains flame intensity and combustion efficiency, preventing combustion interruption and abnormal hot air balloon ascent and descent control due to low-temperature environments.

[0035] The pilot flame valve 23 is connected to the pilot flame nozzle, which is connected to an electronic igniter to continuously provide an ignition source.

[0036] Emergency fire valve 22 is connected to emergency fire nozzle. The valve is equipped with an operable fine-tuning component 26, which is used to adjust the fuel flow to form a stable small fire source in the event of a failure of the pilot light.

[0037] The operable fine-tuning component 26 is the core adjustment component of this invention, mainly composed of an adjustment knob 261, a threaded sleeve 262, a valve stem 263, a valve core 264, a valve seat 265, and a valve port 266. The adjustment knob 261 is fitted onto the threaded sleeve 262 and rotates via a prism drive. The inner wall of the threaded sleeve 262 has matching threads with the outer wall of the valve stem 263, and the valve stem 263 and valve core 264 are coaxially and integrally fixed. When the adjustment knob 261 is rotated, the threaded sleeve 262 rotates, causing the valve stem 263 and valve core 264 to move linearly. The relative displacement between the valve core 264 and the valve seat 265 changes the opening of the valve port 266, achieving fine adjustment of the fuel flow rate. Thus, in the event of a pilot ignition failure, a stable small fire source can be formed by igniting the pilot's own igniter.

[0038] Each combustion unit's pilot flame valve 23, main flame valve 24, and emergency flame valve 22 are connected to the same fuel cylinder via pipelines. During normal flight, the pilot flame valve 23 is opened, the electronic igniter ignites the pilot flame, the main flame valve 24 adjusts the main flame intensity, and the pressure gauge 25 monitors the fuel pressure in real time.

[0039] In the event of a pilot fire malfunction, the main fire valve 24 is closed, the emergency fire valve 22 is opened, the emergency fire flow is adjusted by the operable fine-tuning component 26, and the pilot's own igniter is used to ignite the main fire, forming a stable small fire source.

[0040] In extreme environments, nozzles with larger flow areas are installed on adjustable nozzle orifices to optimize fuel supply and combustion.

[0041] This invention optimizes and simplifies the structure of the burner, removes the original mesh components, achieves overall lightweighting, effectively reduces aircraft load, facilitates transportation, installation and operation, and improves flight performance.

[0042] Based on the above-described preferred embodiments of the present invention, and through the foregoing description, those skilled in the art can make various changes and modifications without departing from the inventive concept. The technical scope of this invention is not limited to the contents of the specification, but must be determined according to the scope of the claims.
