DETAILED DESCRIPTION OF THE EMBODIMENTS

[0028] The following clearly and completely describes the technical scheme in the embodiments of the present disclosure with reference to the embodiments of the present disclosure. Apparently, the described embodiments are merely a part rather than all of the embodiments of the present disclosure. Based on the embodiment in the present disclosure, all other embodiments acquired by the ordinary technical staff in the art under the premise of without contributing creative labor belong to the scope protected by the present disclosure.

[0029] The present disclosure aims to provide a portable gas heating device so as to solve the problems in the prior art, so that the ornamental value and use safety are improved, and the device is convenient to carry.

[0030] To make the foregoing objective, features and advantages of the present disclosure clearer and more comprehensible, the present disclosure is further described in detail below with reference to the attached figures and specific embodiments.

[0031] As shown in FIG. 1 to FIG. 8, the embodiment provides a portable gas heating device. The portable gas heating device includes an intake manifold 12, a body frame 1, a flameout protection module 18 and an anti-toppling switch 19 which are installed on a base inside the body frame 1, and a main valve 14 installed inside the body frame 1. The intake manifold 12 is used for connecting a gas tank, and then gas inside the gas tank passes through the main valve 14 and then is introduced into the small-fire burner system 9 and the main burner system 13 respectively through the intake manifold 12. The main burner system 13 includes a nozzle, an oxygen mixing pipe, and a simulated shape burner which can be firmly installed in the body frame to ensure that the simulated shape burner 7 is safe and unmovable when carried. The body frame 1, such as glass, a metal plate, a metal grating, a metal net and a metal line frame, can protect the circumferential direction of the simulated shape burner 7, and can be adaptively selected by those skilled in the art according to actual requirements so as to improve the protective effect. At least one side wall of the body frame 1 is provided with a side interlayer cavity 6. The top of the side interlayer cavity 6 is provided with a top interlayer cavity 5. A lower end of the side interlayer cavity 6 communicates with the outside, and an upper end of the side interlayer cavity 6 communicates with an air inlet of the top interlayer cavity 5. The exhaust port of the top interlayer cavity 5 communicates with the outside. And then, during burning and heating of the simulated shape burner 7, a great temperature difference exists between upper and lower parts of the body frame, and then air flows to a high-temperature place from a low-temperature place after being heated so as to realize automatic air flow, cool the product outer frame and achieve the temperature requirement of the outer frame when in use. The flameout protection module 18 includes a small-fire burner system 9, an ignition needle 10 and a temperature sensor 8. The small-fire burner system 9 includes a small nozzle, a small oxygen mixing hole and a small-fire burner. When the small-fire burner system 9 is ignited by the ignition needle 10 and burns stably, the temperature sensor 8 detects a temperature signal and transmits the temperature signal to an electromagnetic valve 15 on the main valve 14. The electromagnetic valve 14 controls the intake manifold 12 to supply gas to the simulated shape burner 7 through a rotary knob 4. A flame on the small-fire burner system 9 ignites gas overflowing from the surface of the copying burner 7, and then the effect of safe ignition is achieved. The anti-toppling switch 19 can send a signal to the electromagnetic valve 15 on the main valve 14 to stop all gas supply when the body frame 1 is detected to be toppled at a set angle, and then the effect of flameout protection is achieved to avoid accidents and reduce risks.

[0032] Specifically, the simulated shape burner 7 can be in various decorative shapes such as wood (log) or volcanoes, etc, the gas (real flame) burning on the simulated shape burner 7 in wood or other decorative shapes to achieve a good ornamental value. The interior of the simulated shape burner 7 is provided with an inner flow passage 24 for gas flow. A metal tube 20 is installed on the simulated shape burner 7. Both ends of the metal tube 20 respectively communicate with one end of the internal flow passage 24 and the intake manifold 12, and then gas inside the gas tank is introduced into the internal flow passage 24 through the metal tube 20 and the intake manifold 12. A plurality of grooves are formed in an outer surface of the simulated shape burner 7. Small holes are formed in the outer surface or the grooves of the simulated shape burner 7. The small holes 22 can communicate with the inner flow passage 24, and then gas inside the internal flow passage 24 overflows through the small holes 22 and is burnt outside the small holes 22 so as to achieve the burning effect on the surface of the simulated shape burner 7. Metal wires 23 are installed inside the groove. The metal wires 12 can be resistant to high temperature. The gas overflowing from the small holes 22 is dispersed and mixed with oxygen through the metal wires 23, so that the gas is burnt more sufficiently, and then the content of carbon monoxide in flue gas emission is reduced. At the same time, the metal wires can be burnt until red in the burning process, and then the burning atmosphere is increased, and the effect of thermal radiation heating is increased.

[0033] The simulated shape burner 7 is made of a refractory material which only plays the role of imitating the burning effect of true wood.

[0034] Screws 21 are installed at the bottom of the simulated shape burner 7. The screws 21 can pass through a base plate of the body frame 1 and are fastened through nuts, and then the simulated shape burner 7 is fixed inside the body frame 1 to avoid the simulated shape burner 7 from moving when being moved and carried.

[0035] At least one side wall of the body frame 1 is a non-closed side wall, and in the non-closed side wall, the area of a non-closed part occupies at least 30% of the non-closed side wall. The burning flame on the surface of the simulated shape burner 7 can be observed, and air inside the body frame 1 can communicate with air on the outside conveniently. Namely, external air can effectively enter into the body frame 1 so as to improve the burning effect, and hot air generated by burning is also discharged to the outside conveniently. An upper end of the body frame 1 is provided with a handle 2.

[0036] The thicknesses of the side interlayer cavity 6 and the top interlayer cavity 5 are between 5 mm and 50 mm, so that air can effectively flow inside the side interlayer cavity 6 and the top interlayer cavity 5 to realize heat dissipation. Other air inlet or air outlet slots can also be formed in the side interlayer cavity 6 and top interlayer cavity 5 of the body frame 1, and the side interlayer cavity 6 and top interlayer cavity 5 can be in various shapes.

[0037] The flameout protection module 18 is an ODS (OXYGRNDEPLETIONSENSOR) protection module. A first end of the intake manifold 12 is used for connecting a gas tank, and a second end of the intake manifold 12 is connected to an air inlet of the main valve 14. And then, the gas inside the gas tank is introduced into the main valve 14 through the intake manifold 12 to realize gas supply. When the rotary knob 4 of the main valve 14 is rotated to an ignition position, the small-fire burner system 9 includes a small nozzle, a small oxygen mixing pipe and a small-fire burner. A first air outlet of the main valve 14 is connected to the small-fire burner system through a small-fire burner air pipe 17 of the small-fire burner system 9 so as to supply gas to the small-fire burner. The gas is discharged through the small nozzle of the small-fire burner. A second air outlet of the main valve 14 is sequentially connected to the nozzle and the oxygen mixing pipe of the main burner system 13 and then connected to the simulated shape burner 7. When the gas is supplied to the small-fire burner, an ignition switch is triggered by pressing the rotary knob 4 of the main valve 14, and the small-fire burner burns through the ignition needle 10. The temperature sensor 8 on the flameout protection module 18 senses a stable signal and transmits the signal to the electromagnetic valve 15 on the main valve 14. The electromagnetic valve 15 turns on the constraints of the second air outlet of the main valve 14. The rotary knob 4 on the main valve 14 is rotated to a small fire or large fire gear. The main valve 14 supplies gas to the simulated shape burner 7 through the main burner air pipe 16 of the main burner system 13 and the gas overflows. The gas overflowing on the surface of the simulated shape burner 7 is ignited by the flame on the small-fire burner to realize safe ignition and burning. The rotary knob 4 is used for controlling to supply gas to the small-fire burner, triggering the ignition switch to electrify and ignite the ignition needle 10, controlling to supply gas to the simulated shape burner 7 and adjusting the volume of gas.

[0038] The temperature sensor 8 gets close to an edge of the small-fire burner. When the small-fire burner is ignited, the temperature sensor 8 can detect the temperature of the small-fire burner. When a stable high-temperature signal is detected (at this time, the small-fire burner burns stably), the electromagnetic valve 15 lifts the restrictions on the main valve 14. Gas is opened through the rotary knob 4, and gas is supplied to the simulated shape burner 7 through the main burner air pipe 16 of the main burner system 13. The flame on the small-fire burner ignites the gas overflowing on the simulated shape burner 7 until the flame on the surface of the simulated shape burner 7 begins to burn, namely the device begins to work and operate. When the flame on the small-fire burner or the simulated shape burner 7 is out accidentally (with wind or rain), or when the content of oxygen in surrounding air is lower than the safe oxygen required by human bodies, the temperature sensor 8 detects temperature change and transmits the signal to the electromagnetic valve 15 on the main valve 14. The electromagnetic valve 15 controls the main valve 14 to turn off all gas supply actively. At this time, the small-fire burner and the simulated shape burner 7 are free of gas supply to result in flameout, and then the safety risks caused by gas overflow risks and insufficiency in surrounding oxygen content during accidental flameout are prevented, so that the using safety is ensured.

[0039] The anti-toppling switch 19 can transmit an angle signal to the electromagnetic valve 15 on the main valve 14 when an inclination angle of the body frame 1 is larger than a set angle, and the electromagnetic valve 15 controls the main valve 14 to turn off all gas supply to play a protective role in actively turning off gas flameout during inclination.

[0040] The rotary knob 4 has an ignition gear and a big and small fire adjusting gear. When the rotary knob 4 is rotated to the ignition gear, the main valve 14 can control to supply gas to the small-fire burner system 9. The main valve 14 can trigger the ignition switch to control the ignition needle 10 to ignite the small-fire burner when the rotary knob 4 is pressed. When the flames of the small-fire burner and the main burner system 13 are out accidentally and the oxygen content of surrounding air is lower than safe content of human bodies, the temperature around the temperature sensor 8 can change. The temperature sensor 8 transmits the signal to the electromagnetic valve 15 on the main valve 14 after feeling a stable flame temperature on the small-fire burner. The electromagnetic valve 15 turns on the constraints of gas supply on the main valve 14 to the simulated shape burner 7 after receiving the signal. The volume of gas supplied to the simulated shape burner 7 is adjusted by rotating the rotary knob 4 to different positions in the big and small fire adjusting gear, and then the size of the flame burnt on the simulated shape burner 7 is adjusted.

[0041] A pressure reducing valve 11 is installed on one side of the body frame 1. An air outlet end of the pressure reducing valve 11 is connected to the intake manifold 12. A portable small gas tank can be directly installed at an air inlet of the pressure reducing valve 11, and the air inlet of the pressure reducing valve 11 can also be connected to other gas tanks or gas sources through an external pipe, and then the convenience in the embodiment is realized.

[0042] A fuel bin 3 is installed on one side of the body frame 1, and a gas tank is placed in the fuel bin 3.

[0043] In the embodiment, through the above design, the overall weight can be less than 20 kg (excluding the net weight of the gas tank and the package). The device can be easily carried, can adapt the gas tank specifications popular in the market, has obvious ornamental and heating effects when in use, and can meet the requirements of relevant market safety regulations. Furthermore, according to the portable gas heating device provided by the embodiment, the shape and fixing method of the simulated shape burner, the size and position of each port, the sizes of the small holes 22 and the air outlet slots, and the material and size of the metal wires 23 can be adaptively changed according to actual needs. The gas may be propane, butane, or a mixture of propane and butane.
