Description

Technical Field

[0001] The present invention relates to the technical field of heating equipment, and particularly relates to an outdoor combustion heating device and a usage method thereof. Background Art

[0002] Outdoor heating equipment is an essential equipment for human outdoor activities or outdoor exploration and research, and is mainly applied in scenarios such as heating outdoor sleeping bags and tents, and rescuing accidentally hypothermic persons. Especially in extremely cold regions such as plateaus, high mountains, and high latitudes, heating equipment is an important guarantee for personal and property safety. At present, most of the fuel heating equipment on the market for outdoor adventure in extreme environmental scenarios have a series of problems that pose safety hazards to the human body, such as incomplete combustion of the combustion device generating toxic gases, or excessive carbon dioxide concentration after a period of time in a closed space, and they are bulky and not portable enough, imposing a greater burden on users.

[0003] As a heating device used in people's daily life, a warm air blower is also widely used in outdoor activities. Currently, a general warm air blower is provided with an electric heating device for heating air to meet the heating demand. However, the application of warm air blowers in outdoor activities also has problems: due to high power consumption, it is necessary to carry heavy batteries, resulting in extremely low portability, which greatly limits the application range of warm air blowers in outdoor scenarios. Summary of the Invention

[0004] The purpose of the present invention is to solve the problem of how to reduce the number and weight of vehicle body components under the premise of meeting electrical safety in the prior art.

[0005] To solve the above technical problems, an embodiment of the present invention discloses an outdoor combustion heating device, which includes a air supply mechanism, a combustion mechanism, and a heat exchange mechanism. The air supply mechanism has an air supply duct, the combustion mechanism is detachably arranged on one side of the air supply duct, and the heat exchange mechanism is detachably arranged in the air supply duct at a position corresponding to the combustion mechanism.

[0006] The combustion mechanism includes a burner and a fuel tank that communicate with each other. The burner includes a combustion component and a support housing. One end of the support housing is detachably fixedly connected to one side of the air supply duct, and the combustion component is located on the side close to the heat exchange mechanism within the cavity surrounded by the support housing.

[0007] The heat exchange mechanism includes a fin radiator, which is detachably arranged in the air supply duct. The fin radiator includes a plurality of heat dissipation units, and the plurality of heat dissipation units are spaced and evenly arranged. One end of each heat dissipation unit is connected to the inner side wall of the air supply duct close to the combustion mechanism, and the other end extends in the air supply duct. There is also a heat dissipation cavity between the plurality of heat dissipation units.

[0008] The air supply mechanism includes a blower, an air supply duct, and an air outlet that are interconnected. The blower and the air outlet are respectively located at both ends of the air supply duct and are connected to the air supply duct. The fin radiator is located in the middle of the air supply duct in the length direction. A wind prevention device is provided on one side of the support housing close to the fin radiator. The fin radiator is arranged inside the air supply duct on the side close to the combustion mechanism through the wind prevention device. The wind prevention device includes a support member, a first wind prevention member, and a second wind prevention member. The first wind prevention member and the second wind prevention member are located on both sides of the support member in the extending direction of the air supply duct and are respectively detachably connected to the support member. The support member is arranged at the end of the support housing. Moreover, the bottom parts on both sides of the fin radiator are respectively arranged on the first wind prevention member and the second wind prevention member, and the bottom of the fin radiator is connected to the combustion assembly through the support member.

[0009] With the above technical solution, when the outdoor combustion heating device is used for heating, the combustion mechanism burns gas to provide heat and heats the heat exchange mechanism. The air supply mechanism conveys clean cold air that needs to be heated, and then the clean cold air is heated into clean warm air through the heat exchange mechanism. And when in use, the device can be quickly assembled, and when not in use, it can be disassembled into multiple components for convenient outdoor carrying and use, improving the portability of the device.

[0010] The fuel tank can supply continuous gas or fuel to the burner, and fuel tanks of different specifications or volumes can be selected. The cavity surrounded by the support housing can provide a safe combustion space for the combustion assembly. The fin radiator includes heat dissipation units. When heating the warm air, the heat generated by the burner can be evenly transferred to the fin radiator, and the heat is dispersed from bottom to top on each fin of each heat dissipation unit, with higher heat exchange efficiency. There are also heat dissipation cavities between multiple heat dissipation units. When the clean cold air flows in the air supply duct, it can be evenly distributed in the heat dissipation cavities, and the clean cold air can be evenly heated through the heat dissipation units.

[0011] In order to simultaneously meet the requirements of easy disassembly and high safety, the outdoor combustion heating device is also provided with a wind prevention device. The wind prevention device includes a support member, a first wind prevention member, and a second wind prevention member. Through the wind prevention device, a combined effect of convenient disassembly and installation, good wind prevention effect, and good fire prevention effect is achieved. Moreover, the wind prevention device also has a supporting and positioning effect on the fin radiator, ensuring the safety and high efficiency of the device every time it is assembled and used. Further, the support member can also prevent the flame from tilting caused by uncertain factors, which may lead to the intrusion of flames into the external support structure or the air supply mechanism. To a certain extent, it solves the problem of unstable combustion caused by the external environment and isolates the flame to prevent the ignition of flammable substances. When the support member plays the role of convenient installation and fire prevention, it also plays the first wind prevention role, and the first wind prevention member and the second wind prevention member play the second wind prevention effect, thereby improving the safety of the entire device.

[0012] The first windproof component and the second windproof component can also prevent the high-speed wind in the air supply duct from surging into the burner and affecting the combustion of the burner. At the same time, it ensures that the air in the heat exchange mechanism and the air supply duct is clean and can be directly introduced into a relatively enclosed space without harm to the human body, which is safe and reliable. The detachable, portable, fireproof and windproof effects are achieved through a simple structure.

[0013] An embodiment of the present invention also discloses an outdoor combustion heating device. One side of the support housing close to the fin radiator has a hollowed-out heat dissipation opening. The combustion chamber in the combustion assembly is connected to the heat dissipation opening and is in contact with the fin radiator. The support component is detachably connected to the outer edge of the end of the support housing. One side of the first windproof component and the second windproof component close to the fin radiator is detachably fixed to the support component and is respectively connected to the bottom of the fin radiator. And the first windproof component and the second windproof component cover at least the gap between the heat dissipation opening and the air supply duct between the fin radiator and the support component.

[0014] Adopting the above technical solution, the device provided by the present invention is provided with a hollowed-out heat dissipation opening on one side of the support housing close to the fin radiator, so that the combustion chamber and the fin radiator are communicated. When the fuel in the combustion chamber burns, the flame directly heats the fin radiator to achieve the best heating effect of the burner on the fin radiator and maximize the heat utilization rate of the burner.

[0015] The support component is detachably connected to the outer edge of the end of the support housing, thereby blocking the heat dissipation gap between the support housing and the fin radiator. While the first windproof component and the second windproof component are detachably installed on the support component, they further cover the gap between the heat dissipation opening and the air supply duct, so as to achieve the effect of integrating detachability, good support effect, fireproof and windproof, and being able to be simply disassembled and installed.

And windproof devices are provided on both sides of the air supply duct in the width direction.

The plurality of heat dissipation units are fixedly arranged on one side of the heat dissipation base close to the air supply mechanism, and the other side of the heat dissipation base is connected to the combustion assembly.

[0019] The heat dissipation unit includes a plurality of heat dissipation fins. The plurality of heat dissipation fins are arranged at intervals in a matrix on the heat dissipation base. There is a heat dissipation cavity between any two adjacent heat dissipation fins arranged in a matrix. Moreover, the plurality of heat dissipation cavities communicate with each other and form a plurality of heating channels. In the air supply duct, each heating channel communicates with the air supply duct respectively.

[0020] The air blower conveys clean cold air into the air supply duct. The clean cold air flows through the plurality of heating channels, is heated into clean warm air by the plurality of heat dissipation fins, and is discharged into the internal space to be heated through the air outlet.

When the gas burns in the combustion chamber, the combustion flame directly heats the heat dissipation base, and the heat is transferred to the heat dissipation fins through the heat dissipation base. The metal combustion grille can ensure sufficient air circulation to prevent the flame from incomplete combustion or extinction due to insufficient air. Further, an opening regulating valve is provided at the outlet of the fuel tank of the gas pipeline, which can adjust the opening of the gas pipeline according to the demand, adjust the conveying amount of the gas, and then adjust the size of the combustion flame, and further adjust the heating speed and heating temperature.

When the device is used for heating, the combustion mechanism 200 burns gas to provide heat and heats the heat exchange mechanism. The air supply mechanism 100 conveys clean cold air that needs to be heated, and then the clean cold air is heated into warm air through the heat exchange mechanism. And when in use, the device can be quickly assembled, and when not in use, it can be disassembled into multiple components for convenient outdoor carrying and use, improving the portability of the device, with a simple structure and complete functions.

[0094] The fuel tank 220 can supply continuous gas or fuel to the burner. At the same time, fuel tanks of different specifications or volumes can be selected, such as fuel tanks with different solvents of 3L, 5L, 8L, etc. The joints between the fuel tank and the burner can be connected by threads, and can be screwed and connected during use and disassembled and carried when not in use. And the weight of the device disclosed in this application mainly lies in the weight of the fuel tank, without the need to carry a heavy battery pack, nor will there be a battery anxiety problem. Only a small battery pack is needed to supply power to the blower 120.

[0095] More specifically, to facilitate the use of the device at high altitudes, the fuel tank in this embodiment is preferably a small high-altitude liquefied gas tank, and the high-altitude liquefied gas in the small high-altitude liquefied gas tank can be used and burned normally at high altitudes.

[0096] The cavity surrounded by the support housing 210 can provide a safe combustion space for the combustion assembly. Setting up the support housing 210 can reduce heat loss by 5% - 10%. The combustion assembly can be in the form of a burner head similar to that of a kerosene lamp, or can be set as a nozzle, or can be set as a combustion head with a grille. When the combustion assembly burns, the flame generated by the combustion directly heats the fin radiator 300.

[0097] The fin radiator 300 includes a plurality of heat dissipation units 310. When heating the heating, the heat generated by the burner combustion can be evenly transferred to the fin radiator 300, and the heat is dispersed from bottom to top on each fin of each heat dissipation unit 310, with higher heat exchange efficiency. There is also a heat dissipation cavity between the plurality of heat dissipation units 310. When the clean cold air flows in the air supply duct 110, it can be evenly distributed in the heat dissipation cavity, and the clean cold air can be evenly heated through the heat dissipation units 310.

[0098] Furthermore, in order to simultaneously meet the requirements of convenient disassembly and high safety, the outdoor combustion heating device is also provided with a wind prevention device 400, which includes a support component 410, a first wind prevention component 420, and a second wind prevention component 430.

[0099] First, refer to Figure 2 , in the wind prevention device 400, the support component 410 supports the first wind prevention component 420 and the second wind prevention component 430, and the first wind prevention component 420 and the second wind prevention component 430 also support and connect to the fin radiator 300, ensuring that the fin radiator 300 can be stably installed in the air supply duct 110 and above the burner.

[0100] Secondly, during the disassembly and installation process, refer to Figure 2 , in the wind prevention device 400, the support component 410 is first connected to the support housing 210, then the first wind prevention component 420 and the second wind prevention component 430 are connected to the support component 410, and the first wind prevention component 420 and the second wind prevention component 430 support and connect to the fin radiator 300 and the air supply duct 110.

[0101] Furthermore, the support component 410, the first wind prevention component 420, and the second wind prevention component 430 can also prevent the flame from tilting caused by uncertain factors from entering the external support structure or the air supply mechanism 100. To a certain extent, it solves the problem of unstable combustion caused by the external environment, isolates the flame to prevent the ignition of flammable substances, and safely and reliably separates the combustion mechanism 200 and the air supply mechanism 100.

[0102] Furthermore, the support component 410 can play the first windproof role, and the first windproof component 420 and the second windproof component 430 play the second windproof effect, thereby improving the safety and windproof effect of the entire device. The support component 410, the first windproof component 420, and the second windproof component 430 can prevent the high-speed wind in the air supply duct 110 from surging into the burner and affecting the combustion of the burner. At the same time, it also ensures that the air in the heat exchange mechanism and the air supply duct 110 is clean and can be directly introduced into a relatively enclosed space without harm to the human body, which is safe and reliable.

[0103] Therefore, the windproof device 400 in the present application realizes detachable installation, support, fire prevention, and wind prevention through a simple structure. The windproof device 400 achieves the effects of convenient disassembly and installation, good windproof effect, and good fire prevention effect. Moreover, the windproof device 400 also has a supporting and positioning effect on the fin radiator 300, ensuring the safety and efficiency of the device each time it is assembled and used. The first windproof component 420 and the second windproof component 430 also achieve the effects of detachable portability, fire prevention, and wind prevention through a simple structure.

[0104] The embodiment of the present invention also discloses an outdoor combustion heating device, as Figure 1 and Figure 2 shown, in which one side of the support housing 210 close to the fin radiator 300 has a hollowed-out heat dissipation opening 211. The combustion chamber in the combustion assembly is communicated with the heat dissipation opening 211 and is connected to the fin radiator 300. The support component 410 is detachably connected to the outer edge of the end of the support housing 210. One side of the first windproof component 420 and the second windproof component 430 close to the fin radiator 300 is detachably fixed on the support component 410 and is respectively connected to the bottom of the fin radiator 300. And the first windproof component 420 and the second windproof component 430 cover at least the gap between the heat dissipation opening 211 and the air supply duct 110 between the fin radiator 300 and the support component 410.

[0105] Specifically, in this embodiment, the device provided by the present invention is provided with a hollowed-out heat dissipation opening 211 on one side of the support housing 210 close to the fin radiator 300, so that the combustion chamber and the fin radiator 300 are communicated. The flame generated when the fuel in the combustion chamber burns directly heats the fin radiator 300 to achieve the best heating effect on the fin radiator 300 by the burner and make the heat utilization rate of the burner reach the highest.

[0106] More specifically, when a hollowed-out heat dissipation opening 211 is provided on one side of the support housing 210 close to the fin radiator 300, the heat conversion of the burner to the fin radiator 300 can reach 60% - 80%. When the distance between the burner head in the burner and the fin radiator 300 is 2 cm, the heat conversion rate is the highest.

[0107] The support component 410 is detachably connected to the outer edge of the end of the support housing 210, thereby blocking the heat dissipation gap between the support housing 210 and the fin radiator 300. While the first windproof component 420 and the second windproof component 430 are detachably mounted on the support component 410, they further cover the gap between the heat dissipation port 211 and the air supply duct 110, so as to achieve the effect of integrating detachability, good support, fire prevention and wind prevention, and being able to be simply disassembled and installed.

[0108] It should be noted that during outdoor exploration or outdoor camping, the combustion mechanism 200 can also be used alone, and other activities such as boiling water and cooking can be carried out through the hollow heat dissipation port 211 provided on the support housing 210, with a wide range of applications.

[0109] Another embodiment of the present invention also discloses an outdoor combustion heating device, as Figure 3 and Figure 4 shown. When looking at the support housing 210 from one side of the heat exchange mechanism towards the combustion assembly, the width of the support housing 210 is greater than the width of the air supply duct 110, the width of the air supply duct 110 is greater than the width of the fin radiator 300, and the fin radiator 300 is located in the middle of the support housing 210 within the air supply duct 110. And windproof devices 400 are provided on both side portions in the width direction of the air supply duct 110.

[0110] The width of the air supply duct 110 is greater than the width of the fin radiator 300, which is convenient for installing the fin radiator 300 in the air supply duct 110. And the width of the support housing 210 is greater than the width of the air supply duct 110, enabling windproof devices 400 to be provided on both side portions in the width direction of the air supply duct 110, which can play a role in supporting and installing both side portions of the air supply duct 110, as well as a strict fire prevention and wind prevention effect. The width of the support housing 210 can be 2 - 3 cm greater than the width of the air supply duct 110 to avoid excessive heat loss.

[0111] Furthermore, the width of the air supply duct 110 being greater than the width of the fin radiator 300 also improves the convenience of the device during disassembly and installation. During installation, the support housing 210, the support component 410, the first windproof component 420, the second windproof component 430, and the air supply duct 110 can be bolted and fixed.

[0112] Another embodiment of the present invention also discloses an outdoor combustion heating device. Refer to Figure 2 , the fin radiator 300 includes a heat dissipation base 320 and a plurality of heat dissipation units 310. The plurality of heat dissipation units 310 are fixedly arranged on one side of the heat dissipation base 320 close to the air supply mechanism 100, and the other side of the heat dissipation base 320 is connected to the combustion assembly.

[0113] The heat dissipation unit 310 includes a plurality of heat dissipation fins. The plurality of heat dissipation fins are arranged at intervals in a matrix on the heat dissipation base 320. There is a heat dissipation cavity between any two adjacent heat dissipation fins arranged in a matrix. Moreover, the plurality of heat dissipation cavities communicate with each other and form a plurality of heating channels. Inside the air supply duct 110, each heating channel communicates with the air supply duct 110 respectively.

[0114] The air blower 120 conveys clean cold air into the air supply duct 110. The clean cold air flows through the plurality of heating channels, is heated into clean warm air by the plurality of heat dissipation fins, and is discharged into the internal space to be heated through the air outlet 130.

[0115] Specifically, in this embodiment, the plurality of heat dissipation fins are arranged at intervals in a matrix on the heat dissipation base 320, which can achieve the best space utilization rate. There is a heat dissipation cavity between any two adjacent heat dissipation fins, and the plurality of heat dissipation cavities communicate with each other and form a plurality of heating channels, which can realize the uniform and rapid heating of the clean cold air.

[0116] Among the matrix heat dissipation fins, there is a heat dissipation cavity between two adjacent heat dissipation fins. Along the length direction of the air supply duct 110 or the direction of air flow in the air supply duct 110, the plurality of heat dissipation cavities communicate with each other and form a plurality of heating channels. When the clean cold air flows through the heating channels, it is heated by the heat dissipation fins. The heating effect of the plurality of heat dissipation fins is better and the heating speed is faster.

[0117] More specifically, the plurality of heat dissipation fins can be arranged in the way of 4*4, 5*5, 6*6, n*n, or can be arranged in the way of 4*6, 5*7, 6*8, n*m. This embodiment does not make specific limitations on this.

[0118] More specifically, the heat dissipation fins can be a regular cuboid sheet structure, cuboid column structure, prismatic structure, etc., or can be set to have a larger volume on the side close to the heat dissipation base 320 and a smaller volume on the side far from the heat dissipation base 320, because when heat is transferred on the heat dissipation fins, the heat of the heat dissipation fins is lower on the side farther from the heat dissipation base 320. The material of the heat dissipation fins can be made of iron, copper, alloy or other metal materials. This embodiment does not make specific limitations on this.

[0119] Another embodiment of the present invention also discloses an outdoor combustion heating device. The combustion assembly includes a combustion head and a connection tail (not shown in the figure) that communicate with each other. The combustion head includes a metal combustion grille and a connection handle. The metal combustion grille is located at a position close to the heat dissipation base 320 and is connected to the heat dissipation base 320. There is a combustion chamber inside the metal combustion grille. The combustion flame of the combustion head burns in the combustion chamber and heats the heat dissipation base 320 and the heat dissipation fins. The connection handle communicates with the connection tail, and the connection tail is detachably connected to the fuel tank 220.

[0120] A gas pipeline is provided between the fuel tank 220, the connecting handle and the connecting tail; an opening regulating valve is provided at the outlet of the fuel tank 220 of the gas pipeline.

[0121] The combustion head includes a metal combustion grille and a connecting handle, which facilitates the mixing of gas and air. The metal combustion grille is located near the heat dissipation base 320 and is connected to the heat dissipation base 320. When the gas burns in the combustion chamber, the combustion flame directly heats the heat dissipation base 320, and the heat is transferred to the heat dissipation fins through the heat dissipation base 320. The metal combustion grille can ensure sufficient air circulation to prevent the flame from incomplete combustion or extinction due to insufficient air. Further, an opening regulating valve is provided at the outlet of the fuel tank 220 of the gas pipeline, which can adjust the opening of the gas pipeline according to the demand, adjust the gas delivery volume, and then adjust the size of the combustion flame, and further adjust the heating speed and heating temperature.

[0122] In the specific use process, the opening regulating valve provided at the outlet of the fuel tank 220 is opened, and the valve is opened to a suitable position to release gas from the fuel tank 220 or the high-cold liquefied gas tank. After the gas is ejected by the combustion head and semi-premixed with air, the gas is ignited by the igniter, so that the combustion flame of the combustion head burns in the metal combustion grille and heats the fin radiator 300.

[0123] It should be noted that those skilled in the art can also adjust or design the combustion head into other structures according to actual needs. For example, a bowl-shaped or concave structure is provided in the combustion head, and the opening faces the fin radiator 300. The flame in the burner burns in the combustion head, which can prevent the outdoor wind from blowing out the flame. This embodiment does not make specific limitations on this.

[0124] Another embodiment of the present invention also discloses an outdoor combustion heating device, see Figure 1 , the support housing 210 has a square structure and surrounds the burner. A plurality of ventilation and smoke exhaust openings 212 are provided on the outer side wall of the support housing 210.

[0125] Moreover, when looking at the burner from the outside of the support housing 210, the plurality of ventilation and smoke exhaust openings 212 are spaced apart from and misaligned with the grille holes on the metal combustion grille.

[0126] With this structural design, the plurality of ventilation and smoke exhaust openings 212 are used to discharge smoke. When looking at the burner from the outside of the support housing 210, the plurality of ventilation and smoke exhaust openings 212 are spaced apart from and misaligned with the grille holes on the metal combustion grille. That is, any ventilation and smoke exhaust opening 212 is misaligned with the grille hole. Even when the outdoor wind blows towards the support housing 210, it can prevent the outdoor wind from directly blowing towards the flame in the combustion chamber, thereby preventing the flame burning in the burner from being blown out by the outdoor wind.

[0127] Another embodiment of the present invention also discloses an outdoor combustion heating device. An igniter is provided on one side of the combustion assembly. The igniter includes a piezoelectric ceramic lighter and / or a high-voltage pulsed electric spark lighter.

[0128] Specifically, in this embodiment, it is preferably equipped with two ignition devices. It can use the piezoelectric ceramic for manual ignition, and at the same time, it can also use the high-voltage pulsed electric spark lighter to ensure the safe ignition of the device and ensure its normal use in case of emergencies.

[0129] Another embodiment of the present invention also discloses an outdoor combustion heating device. Refer to Figure 1 、 Figure 3 and Figure 4 , the air supply duct 110 includes a first air supply reducer 111, a front air supply duct 112, a rear air supply duct 114, and a second air supply reducer 116 that are detachably connected in sequence from the air supply fan 120 towards the air outlet 130.

[0130] The first air supply reducer 111 is a frustum-shaped air supply duct. One end of the first air supply reducer 111 is connected to the air supply fan 120, and the other end is connected to the front air supply duct 112. The end face of the first air supply reducer 111 connected to the air supply fan 120 is larger than the end face of the end connected to the front air supply duct 112. The front air supply duct 112 and the rear air supply duct 114 are square air supply ducts. The fin radiator 300 is located in the cavity inside the front air supply duct 112 and the rear air supply duct 114.

[0131] One end of the second air supply reducer 116 is connected to the rear air supply duct 114, and the other end is provided with an air outlet 130. The cross-sectional shape of the air outlet 130 is circular, and the cross-sectional area of the side end face of the second air supply reducer 116 connected to the rear air supply duct 114 is larger than the cross-sectional area of the air outlet 130. Among them, the clean cold air passes through the first air supply reducer 111 and the front air supply duct 112 in sequence and is heated into clean warm air by the fin radiator 300, and is discharged into the internal space through the rear air supply duct 114, the second air supply reducer 116, and the air outlet 130.

[0132] The first air supply reducer 111, the front air supply duct 112, the rear air supply duct 114, and the second air supply reducer 116 can form a complete air supply channel, and the fin radiator 300 is located in the middle of the air supply channel. When the clean cold air is transported in the air supply channel, it can be heated into clean warm air by the fin radiator 300, so as to heat the tent or sleeping bag.

[0133] Furthermore, in this application, by setting the air supply channel of the reducer, the diameter from the air inlet of the clean cold air to the air outlet gradually becomes smaller, which can make the wind speed faster and the temperature of the heated warm air higher.

[0134] More specifically, in this embodiment, the first air supply reducer pipe 111, the front side air supply pipe 112, the rear side air supply pipe 114, and the second air supply reducer pipe 116 can also be set as circular pipes or pipes of other shapes, and this embodiment does not make specific limitations on this.

On both sides of the outer side wall of the rear side air supply pipe 114 connected to the combustion mechanism 200, there are also provided rear side sealing flanges 115, and the rear side sealing flanges 115 are attached to and detachably fixedly connected to the second windproof component 430.

[0136] In the length direction of the air supply pipe, the front side air supply pipe 112 and the rear side air supply pipe 114 are symmetrically distributed along the center line of the fin radiator 300 respectively, and the front side sealing flanges 113 and the rear side sealing flanges 115 are symmetrically distributed along the center line of the fin radiator 300 respectively.

[0137] Specifically, on both sides of the outer side wall of the front side air supply pipe 112 connected to the combustion mechanism 200, there are also provided front side sealing flanges 113, which can facilitate the connection between the air supply duct 110 and the windproof device 400 and facilitate the installation and use of this device.

[0138] More specifically, a digital display thermometer 117 is detachably provided on the second air supply reducer pipe 116. And a air supply duct is detachably provided at the air outlet 130. The digital display thermometer 117 can display the temperature of the warm air discharged into the internal space from the air outlet 130, and the temperature of the warm air can be adjusted according to the temperature display as a reference.

[0139] Another embodiment of the present invention also discloses an outdoor combustion heating device. The outer side walls of the first air supply reducer pipe 111, the front side air supply pipe 112, the rear side air supply pipe 114, the second air supply reducer pipe 116, and the support housing 210 are all coated with a heat insulation and heat preservation component. The heat insulation and heat preservation component at least includes a refractory foam layer and a heat preservation aluminum foil layer which are stacked. Setting the heat insulation and heat preservation component can greatly reduce the heat loss and improve the heat exchange efficiency.

[0140] Specifically, in this embodiment, when the heat insulation component is wrapped, after the support housing 210, the air supply duct 110, the support member 410, the first windproof member 420, and the second windproof member 430 are connected and fixed together by threads or bolts, the heat insulation component is wrapped and pasted on the extension connection bracket of the air supply duct 110, thereby improving the heat insulation effect of the air supply duct 110. It should be noted that those skilled in the art can also set heat insulation components made of other materials according to actual needs, as long as the heat insulation component has a certain heat insulation effect.

[0143] Specifically, both the automatic air blower and the manual air blower can deliver clean cold air into the air supply duct 110, and the wind speed can also be adjusted, which can improve the comfort of outdoor use.

[0144] For the automatic air blower, refer to Figure 1 , components such as a motor and a fan can also be provided inside the housing, as long as it can continuously deliver clean cold air into the air supply duct 110. When set as an automatic air blower, the air outlet speed is adjustable. The automatic air blower can be speed-controlled by PWM technology. For example, it can be achieved by setting the manual knob or manual button of the PWM speed control board, or it can also be achieved by controlling the Arduino board to output a PWM signal through the mobile phone Bluetooth function, or other methods can also be used for control.

[0145] Taking the actual working process of the device disclosed in the present invention as an example for illustration: The air outlet temperature, air outlet speed, etc. are adjusted through the automatic air blower. For example, the air supply fan can be regulated for speed control. For example, the basic air volume can be adjusted to 40m 3 / h, 55m 3 / h, 60m 3 / h, 70m 3 / h, etc. The air outlet temperature can also be adjusted. For example, the average air outlet temperature can be 17°C, 20°C, 22°C, 25°C, etc. This embodiment does not make specific limitations on this.

[0146] The manual air blower can be used as an emergency device. When the automatic air blower is damaged or the power supply component 500 has no power, the user can turn the rotating handle to deliver clean cold air into the air supply duct 110. Its principle is the same as that of the automatic air blower, except that the automatic air blower is driven by electricity, while the manual air blower is hand-cranked by the user to deliver clean cold air.

It should be noted that Figure 5 This is only a classification description of one of the specific structures of Figure 1 the device, and it is not the specific structure classification of the device.

[0156] In summary, this embodiment discloses an outdoor combustion heating device.

[0161] S1. Assemble the combustion mechanism 200, the heat exchange mechanism, and the air supply mechanism 100 to form a combustion heating device and conduct a sealing inspection;

[0162] S2. Open the fuel tank 220 and ignite the fuel conveyed by the burner through the igniter. The flue gas discharged when the burner burns is discharged into the first external environment;

[0163] S3. Start the air blower 120. The air blower 120 compresses and absorbs the clean cold air in the second external environment, and conveys the clean cold air in the air supply duct 110 through the air supply duct 110;

[0164] S4. The clean cold air is heated into clean warm air by the fin radiator 300, and the clean warm air is discharged into the internal space to be heated through the air outlet 130. A heating external circulation is formed between the second external environment, the air supply mechanism 100, and the heat exchange mechanism and the internal space.

[0165] Specifically, in step S1, when performing a seal check on the combustion heating device, mainly check the parts of the air supply duct 110 where the heat exchange mechanism is installed and the parts where the combustion mechanism 200 is installed, that is, check whether the parts where the wind prevention device 400 is located are sealed, so as to ensure that the device has good fire prevention and wind prevention effects during combustion heating. Secondly, check whether the air supply duct 110 is sealed to prevent leakage when transporting clean cold air or clean warm air in the air supply duct 110. At the same time, also check the connection between the burner and the fuel tank 220 and whether the igniter can ignite normally.

[0166] More specifically, during the use of the device, reference can be made to Figure 6 , the flue gas discharged during the combustion of the combustion device is discharged into the first external environment, and the clean cold air to be heated is compressed and absorbed in the second external environment, which can avoid inhaling cold air with flue gas, improve the safety of the device, and realize the heating external circulation between the second external environment and the internal space to be heated. Thus, continuously provide clean warm air to the internal space to be heated, and use the heated air to maintain the temperature of the warm space, creating a more comfortable camping environment.

In step S3, the air supply fan 120 compresses and absorbs the clean internal air in the internal space and transports the internal air in the air supply duct 110 through the air supply duct 110. In step S4, the internal air is heated into clean warm air by the fin radiator 300, and the clean warm air is discharged into the internal space to be heated through the air outlet 130. The air in the internal space forms a heating internal circulation through the air supply mechanism 100 and the heat exchange mechanism.

[0168] Specifically, in this embodiment, as Figure 7 shown, the heating internal circulation of the internal air can be directly realized through the air supply mechanism 100 and the heat exchange mechanism. It can well heat a relatively large space such as a tent. It should be noted that when performing the heating internal circulation, place the air supply mechanism 100 in the space to be heated and place the burner in the external space to prevent the flue gas from being discharged into the internal space.

[0169] Furthermore, it should be noted that the outdoor combustion heating device disclosed in this application can also be applied to the first aid work of medical staff in high-cold regions. Using this device, hypothermic patients can be rewarmed. The specific method is roughly the same as the normal usage method. During use, first wrap and cover the film air duct outside the body of the hypothermic patient, then connect the air outlet 130 to the film air duct, and supply hot air into the film air duct through the air outlet 130 to provide a continuously warm and insulated space for the hypothermic patient, so that the hypothermic patient can quickly return to a normal body temperature.

[0170] Therefore, a film air duct that can be used in conjunction with the outdoor combustion heating device in this application can be provided. The film air duct can be in the same shape as the human body and can be worn or put on the outside of the hypothermic patient, or it can be wound around the outside of the hypothermic patient. When warm air is delivered into the film air duct, the film air duct will inflate and maintain a space with a relatively high temperature, so that the hypothermic patient can quickly return to a normal body temperature. And hikers can also use it outdoors by themselves, and it can also be used in combination with sleeping bags or tents.

The outdoor combustion heating device includes a air supply mechanism 100, a combustion mechanism 200, and a heat exchange mechanism. When the outdoor combustion heating device is used for heating, the combustion mechanism 200 burns gas to provide heat and heats the heat exchange mechanism. The air supply mechanism 100 conveys clean cold air that needs to be heated, and then the clean cold air is heated into warm air through the heat exchange mechanism. The heat exchange mechanism is arranged as a fin radiator 300. When the clean cold air flows in the air supply pipeline 110, it can be evenly distributed in the heat dissipation cavity inside the fin radiator 300, and the clean cold air can be evenly heated through the heat dissipation fins. And a windproof device 400 is arranged on one side of the combustion mechanism 200 close to the heat exchange mechanism. The windproof device 400 has a supporting and positioning effect on the fin radiator 300; it is also convenient to disassemble and install the fin radiator 300; it also has a good fire prevention effect, isolating the flame to prevent the ignition of flammable substances; and it also has a two-layer windproof effect to prevent the high-speed wind in the air supply pipeline 110 from surging into the burner and affecting the combustion of the burner.

[0172] Therefore, the outdoor combustion heating device disclosed in this application has the advantages of being convenient to disassemble and carry, high safety performance, wide application range, high heating efficiency, and fast warm air speed. When the device is used, it can be quickly assembled and used, and can be used for heating in an external circulation or heating in an internal circulation according to actual needs to meet different outdoor requirements and ensure the safety of the warm air.
