Description

Technical Field

[0001] This utility model relates to the field of heating equipment technology, and in particular to a gas-fired heating device. Background Technology

[0002] Most portable gas heaters on the market currently use ceramic plate burners as their core heating element. These burners are traditional infrared radiation type designs. Their working principle involves incomplete combustion of gas and air on the surface of a ceramic plate, generating infrared radiation for heating. However, most gas heaters under current technology have two significant drawbacks: firstly, their heat conversion efficiency is poor, generally below 80%, resulting in a large amount of gas energy being lost as exhaust gas; secondly, their heating response is slow, typically requiring a long preheating time from startup to reaching the set temperature. This delay significantly reduces user comfort in cold environments. Utility Model Content

[0003] In view of this, the purpose of this utility model is to overcome the shortcomings of related technologies, and this utility model provides a gas heating device.

[0004] This utility model provides the following technical solution: A gas-fired heating device includes a body, a combustion component, and an ignition component.

[0005] A heat release port is provided on the side wall of the machine body, and a gas tank is provided inside the machine body. The combustion assembly is installed on the machine body, and the combustion assembly includes a combustion chamber and a burner. One side of the combustion chamber is provided with a connecting port. The combustion chamber is located inside the machine body, and its connecting port is connected to the heat release port. The burner is located on the side wall of the combustion chamber. The burner has an air inlet and a combustion port. The air inlet is connected to the air outlet of the gas tank through a first gas supply pipe. The opening of the combustion port is perpendicular to the opening direction of the connecting port. The ignition assembly includes an igniter corresponding to the burner. The igniter is located in the combustion chamber. The igniter can ignite the gas ejected from the combustion port. The flame after the gas ejected from the combustion port is ignited is blue.

[0006] As a further improvement to the above technical solution, the burner has multiple combustion ports arranged side by side, and a curved gas delivery channel is laid inside the burner. The gas delivery channel is connected to each of the combustion ports and the air inlet. The first gas delivery pipe is arranged near the opening of the burner and opposite to the air inlet. When the first gas delivery pipe sprays gas into the air inlet, it can carry air into the gas delivery channel.

[0007] As a further improvement to the above technical solution, the ignition assembly also includes an ignition base, which is connected to the gas outlet of the gas cylinder through a second gas supply pipe. The ignition base is provided with an ignition hole that is connected to the second gas supply pipe, and the igniter is capable of igniting the gas ejected from the ignition hole.

[0008] As a further improvement to the above technical solution, the machine body is provided with a rotary switch, and a control valve is provided between the first gas supply pipe, the second gas supply pipe and the gas outlet of the gas cylinder. The rotary switch is respectively connected to the control valve and the igniter. Pressing the rotary switch can drive the igniter to be energized and ignited; rotating the rotary switch can cause the control valve to sequentially control the gas outlet of the gas cylinder to connect with the first gas supply pipe and the second gas supply pipe.

[0009] As a further improvement to the above technical solution, the ignition assembly further includes a temperature sensor, which is connected to the control valve. The sensing end of the temperature sensor is set within the combustion range when the gas injected from the ignition hole is burned, in order to sense the combustion state of the gas injected from the ignition hole. When the sensing end of the temperature sensor does not sense the temperature generated by combustion, it can feed back a signal to the control valve, causing it to cut off the connection between the gas outlet of the gas cylinder and the first gas supply pipe and the second gas supply pipe.

[0010] As a further improvement to the above technical solution, a heat insulation plate is also provided inside the machine body, and the heat insulation plate is located between the combustion chamber and the gas tank.

[0011] As a further improvement to the above technical solution, an isolation boss is provided around the periphery of the heat dissipation port.

[0012] As a further improvement to the above technical solution, the body is provided with heat dissipation holes evenly distributed on the heat dissipation port end face, the heat dissipation holes being used to connect the interior of the body with the outside.

[0013] As a further improvement to the above technical solution, the body is also provided with a protective net, which covers the outside of the heat dissipation port.

[0014] As a further improvement to the above technical solution, a fireproof glass is provided at the position of the protective net opposite the combustion chamber interface.

[0015] Compared with related technologies, the beneficial effects of this utility model are: The gas heating device provided by this utility model, when started by the user, first uses the igniter in the ignition assembly to ignite the gas, providing an ignition source for subsequent gas combustion. Then, the gas stored in the gas tank is transported to the burner of the combustion assembly through the first gas supply pipe. After being regulated and distributed inside the burner, the gas is ejected from the burner's combustion port into the combustion chamber.

[0016] At this point, the gas ejected from the burner comes into contact with the spark generated by the igniter, igniting instantly and forming a stable flame. This combustion process occurs within the combustion chamber, which is connected to the outside environment through heat dissipation vents on the side wall of the unit. In this way, the heat generated by the combustion of the gas can be efficiently and evenly dissipated into the surrounding environment through the heat dissipation vents, providing users with a warm and comfortable heating experience.

[0017] It is worth mentioning that in the gas heating device of this utility model, the gas is ignited directly from the combustion port by an igniter. This design effectively improves the heat energy conversion efficiency of the gas. Because the gas is ignited instantly upon ejection, heat loss during the transfer process is reduced, allowing more heat energy to be converted into usable heating energy. At the same time, this direct ignition method allows the flame to directly radiate heat without undergoing a complex heat exchange process, thus greatly improving the heating response speed and allowing users to quickly feel warmth.

[0018] Furthermore, this utility model's gas heating device features a visual representation of the combustion status. During complete combustion of the gas, a bright blue flame is produced, indicating incomplete combustion. When combustion is incomplete, the flame will appear yellow or orange-red. This color change visually reflects the burner's combustion status. Users can easily determine if the burner is working properly by observing the flame color through the heat outlet, allowing for timely maintenance and adjustments. This design not only facilitates daily management and maintenance but also significantly reduces safety hazards caused by burner malfunctions.

[0019] Meanwhile, users will naturally be more vigilant when they see an open flame to avoid accidental burns or other unforeseen circumstances. Therefore, this gas-fired heating device also takes into account safety. Furthermore, the blue flame produced when the gas burns completely also has a decorative effect, enhancing the environment in which the device is used and improving the user experience.

[0029] Combination Figure 2 , Figure 4 , Figure 5 , Figure 6 As shown, an embodiment of this utility model provides a gas heating device, including a body 100, a combustion component 200, and an ignition component 300.

[0030] A heat release port 110 is provided on the side wall of the body 100, and a gas tank is provided inside the body 100; the combustion assembly 200 is installed on the body 100, and the combustion assembly 200 includes a combustion chamber 210 and a burner 220. One side of the combustion chamber 210 is provided with a connection port 211. The combustion chamber 210 is located inside the body 100, and its connection port 211 is connected to the heat release port 110. The burner 220 is located on the side wall of the combustion chamber 210, and the burner 220 has… It has an air inlet 221 and a combustion port 222. The air inlet 221 is connected to the gas outlet of the gas cylinder through a first gas supply pipe 223. The opening of the combustion port 222 is perpendicular to the opening direction of the connecting port 211. The ignition assembly 300 includes an igniter 310 corresponding to the burner 220. The igniter 310 is disposed in the combustion chamber 210. The igniter 310 can ignite the gas sprayed from the combustion port 222. The flame after the gas sprayed from the combustion port 222 is ignited is blue.

[0031] The gas heating device provided in this embodiment, when started by a user, first uses the igniter 310 in the ignition assembly 300 to ignite the gas, providing an ignition source for subsequent gas combustion. Then, the gas stored in the gas tank is transported to the burner 220 of the combustion assembly 200 through the first gas supply pipe 223. After being regulated and distributed inside the burner 220, the gas is ejected from the combustion port 222 of the burner 220 into the combustion chamber 210.

[0032] At this moment, the gas ejected from the burner 220 comes into contact with the spark generated by the igniter 310, igniting instantly and forming a stable flame. This combustion process occurs within the combustion chamber 210, which is connected to the outside world through the heat dissipation port 110 on the side wall of the unit 100. In this way, the heat generated by the combustion of the gas can be efficiently and evenly dissipated into the surrounding environment through the heat dissipation port 110, providing users with a warm and comfortable heating experience.

[0033] It is worth mentioning that in this embodiment, the gas directly ejected from the combustion port 222 is ignited by the igniter 310. This design effectively improves the thermal energy conversion efficiency of the gas. Because the gas is ignited instantly upon ejection, heat loss during the transfer process is reduced, allowing more thermal energy to be converted into usable heating energy. Simultaneously, this direct ignition method allows the flame to directly radiate heat without undergoing a complex heat exchange process, thereby greatly improving the heating response speed and enabling users to quickly feel warmth.

[0034] Furthermore, this embodiment also features a visual representation of the combustion status. During complete combustion of the gas, a bright blue flame is produced, indicating incomplete combustion. When combustion is incomplete, the flame will appear yellow or orange-red. This color change visually reflects the combustion status of the burner 220. Users can easily determine whether the burner 220 is working properly by observing the flame color through the heat outlet 110, allowing for timely maintenance and adjustments. This design not only facilitates daily management and maintenance of the equipment but also significantly reduces safety hazards caused by burner 220 malfunctions.

[0035] Meanwhile, users will naturally be more vigilant when they see an open flame to avoid accidental burns or other unforeseen circumstances. Therefore, this embodiment also takes comprehensive consideration into account to ensure safety. Furthermore, the blue flame produced when the gas is fully burned also has a decorative effect, enhancing the environment in which the equipment is used and improving the user experience.

[0036] In some specific embodiments, the burner 220 has multiple combustion ports 222 arranged side by side to increase the combustion range of the flame, increase the heating area, and improve the heating efficiency for users. The burner 220 has a curved gas delivery channel, which is connected to each of the combustion ports 222 and the air inlet. The opening of the first gas delivery pipe 223 near the burner 220 is opposite to the air inlet 221, and there is a gap between the opening of the first gas delivery pipe 223 near the burner 220 and the air inlet 221. The air inlet 221 has a funnel-shaped opening. When the first gas delivery pipe 223 sprays gas into the air inlet 221, it can carry air into the gas delivery channel. After the gas carries air into the gas delivery channel, it can be fully mixed after passing through multiple bends in the gas delivery channel, making the gas burn more completely after being sprayed from the combustion ports 222 of the burner 220, thus improving the safety of this embodiment.

[0037] In some specific embodiments, the ignition assembly 300 further includes an ignition base 320, which is connected to the gas outlet of the gas cylinder via a second gas supply pipe 322. The ignition base 320 is provided with an ignition hole 321 connected to the second gas supply pipe 322, and the igniter 310 can ignite the gas ejected from the ignition hole 321. In practical applications, the gas cylinder continuously supplies gas to the ignition base 320 via the second gas supply pipe 322. After reaching the ignition base 320, this gas is ejected through the ignition hole 321 at a certain speed and pressure. At the same time, upon receiving an ignition signal, the igniter 310 immediately generates an electric spark or a high-temperature flame, which ignites the gas ejected from the ignition hole 321. Once the gas is successfully ignited, a stable flame will form at the ignition port 321. This flame is called a pilot flame. When the gas is ejected from the combustion port 222, the flame at the ignition port 321 can ignite the gas ejected from the combustion port 222. The flame after the gas ejected from the combustion port 222 is ignited is blue, ensuring the reliability of the ignition process of the burner 220.

[0038] The presence of a permanent flame is crucial for the entire heating system. As a continuous ignition source for burner 220, it ensures that burner 220 can quickly and stably initiate the combustion process when heating is needed. In other words, because the ignition port 321 of the ignition base 320 maintains its permanent flame function under the ignition action of igniter 310, burner 220 can immediately obtain a stable and reliable ignition source whenever heating is required, thus ensuring the reliability and stability of the heating system in this embodiment.

[0039] In some specific embodiments, the body 100 is equipped with a rotary switch 120, and a control valve 130 is provided between the first gas supply pipe 223, the second gas supply pipe 322, and the gas outlet of the gas cylinder. The rotary switch 120 is connected to the control valve 130 and the igniter 310 respectively. Pressing the rotary switch 120 can drive the igniter 310 to ignite; rotating the rotary switch 120 can cause the control valve 130 to sequentially control the gas outlet of the gas cylinder to connect with the first gas supply pipe 223 and the second gas supply pipe 322. Specifically, when using this embodiment, the user first presses the rotary switch 120 to drive the igniter 310 to ignite. Then, rotating the rotary switch 120 connects the gas outlet of the gas cylinder with the second gas supply pipe 322, supplying gas to the ignition base 320. At this time, the igniter 310 will ignite the gas ejected from the ignition hole 321 of the ignition base 320. Then, continue rotating the knob switch 120 in the same direction to connect the gas cylinder outlet to the first gas supply pipe 223, supplying gas to the burner 220. At this time, the flame at the ignition port 321 will ignite the gas ejected from the combustion port 222 of the burner 220, thereby providing heating for the user. Finally, continue rotating the knob switch 120 in the same direction to adjust the gas supply speed between the gas cylinder outlet and the first gas supply pipe 223, thereby adjusting the flame size at the combustion port 222 of the burner 220. The above operation process is simple and efficient, improving the user experience.

[0040] In some specific embodiments, the ignition assembly 300 further includes a temperature sensor 330, which is controlled and connected to the control valve 130. The sensing end 331 of the temperature sensor 330 is located within the combustion range when the gas ejected from the ignition port 321 is burning, and is used to sense the combustion state of the gas ejected from the ignition port 321. When the sensing end 331 of the temperature sensor 330 does not sense the temperature generated by combustion, it can feed back a signal to the control valve 130, causing it to cut off the connection between the gas outlet of the gas cylinder and the first gas supply pipe 223 and the second gas supply pipe 322, in order to avoid gas leakage and potential danger. For example, when the gas is burning normally, the combustion range will generate a stable temperature within a certain range, and the sensing end 331 of the temperature sensor 330 can sensitively capture this temperature signal. When the gas combustion is abnormal, such as when the flame goes out, the temperature of the combustion range will drop rapidly, and the temperature sensor 330 can also detect this change in a timely manner.

[0041] During actual operation, the temperature sensor 330 is constantly monitoring. If its sensing end 331 fails to detect the temperature generated by combustion, it indicates that the gas ejected from the ignition port 321 may not be burning properly, posing a potential risk of continuous gas leakage. In this case, the temperature sensor 330 reacts quickly, immediately sending a signal to the control valve 130. Upon receiving this signal, the control valve 130 quickly disconnects the gas cylinder's outlet from the first gas supply pipe 223 and the second gas supply pipe 322. This prevents the gas from continuing to be delivered to the ignition base 320 and burner 220 through the gas supply pipes, thus avoiding the possibility of gas leakage and potential danger at the source. By adding the temperature sensor 330 and constructing such a control mechanism, the user safety of this embodiment can be effectively improved.

[0042] like Figure 3 As shown, in some specific embodiments, a heat insulation plate 140 is also provided inside the body 100, and the heat insulation plate 140 is located between the combustion chamber 210 and the gas tank. By setting the heat insulation plate 140, the heat in the combustion chamber 210 is prevented from being directly transferred to the gas tank, so that the gas tank is always in a relatively stable temperature environment. In this way, the gas pressure in the gas tank can be maintained within a safe range, reducing the possibility of damage or danger to the gas tank due to high temperature, thereby significantly improving the safety of the gas tank and ensuring the stability and reliability of the entire equipment during operation.

[0043] In some specific embodiments, the heat release port 110 is surrounded by an isolation protrusion 150 to extend the distance between the combustion chamber 210 and the outside, reduce the probability of flames protruding from the heat release port 110, and improve the safety of use in this embodiment.

[0044] In some specific embodiments, the body 100 is provided with heat dissipation holes 160 evenly distributed on the end face of the heat dissipation port 110. The heat dissipation holes 160 are used to connect the interior of the body 100 with the outside world, thereby reducing the probability of heat accumulation problems inside the body 100, avoiding damage or danger to the gas tank due to high temperature, and further improving the safety of the gas tank in this embodiment.

[0045] like Figure 1 As shown, in some specific embodiments, the body 100 is also provided with a protective net 170, which covers the outside of the heat release port 110 to isolate the user's body from the combustion chamber 210, avoid burns to the user, and ensure the safety of use in this embodiment.

[0046] In some specific embodiments, a fireproof glass 171 is provided at the position of the protective net 170 opposite the interface 211 of the combustion chamber 210 to isolate the flame in the combustion chamber 210 from the outside world and guide its extension direction, thereby improving the reliability of this embodiment.
