Description

Technical Field

[0001] The present invention relates to outdoor stoves, and in particular to a cartridge stove, a stove system and a burning method of the cartridge stove. Background Art

[0002] A cartridge stove is a common outdoor stove that generates flame by burning fuel (usually butane) in a gas cylinder. Butane is a flammable and explosive gas that needs to be oxidized and stored in a dedicated gas cylinder. Typically, the gas cylinder is equipped with an L-shaped valve tube. Once the gas cylinder is installed on the cartridge stove, the inlet end of the valve tube always faces upward, allowing a small amount of gaseous fuel in the cylinder to be transported through the valve tube to the burner of the cartridge stove for combustion. In other words, existing cartridge stoves only allow the cylinder to output gaseous fuel, which requires the fuel to complete a liquid-to-gas phase transition within the cylinder. As is well known, the fuel continuously absorbs heat during this transition. Therefore, this process causes the cylinder temperature to drop continuously, leading to a continuous decrease in the cylinder pressure. This, in turn, reduces the flow of gaseous fuel from the cylinder to the burner, ultimately causing the flame of the cartridge stove to shrink or even go out. Summary of the Invention

[0003] An object of the present invention is to provide a cartridge stove, a stove system, and a cartridge stove combustion method, wherein when the cartridge stove burns the liquid fuel output from the gas cylinder for a long time, the flame generated by the cartridge stove can remain stable, that is, the flame generated by the cartridge stove due to the combustion of the mixed fuel will not decrease as the time for the gas cylinder to output the liquid fuel increases.

[0004] One object of the present invention is to provide a cartridge stove, a stove system, and a cartridge stove combustion method, wherein during the continuous use of the cartridge stove, the fuel output by the gas tank is liquid fuel. Unlike existing cartridge stoves that require the fuel to complete the conversion from liquid phase to gas phase within the gas tank, the cartridge stove of the present invention requires the gas tank to continuously output liquid fuel. During this process, the pressure within the gas tank will not decrease due to an increase in the time of outputting liquid fuel, thereby allowing the gas tank to continuously and stably output liquid fuel to maintain the stability of the flame generated by the combustion of the mixed fuel in the cartridge stove.

[0005] One object of the present invention is to provide a cartridge stove, a stove system, and a cartridge stove combustion method, wherein during the process of the cartridge stove's fuel pipeline transporting liquid fuel from the gas tank to the burner head, the liquid fuel can be vaporized into gaseous fuel. In this way, the cartridge stove of the present invention can achieve the purpose of maintaining the flame stability generated by the combustion of the mixed fuel in the cartridge stove without improving the structure of the burner head, thereby helping to reduce the technical difficulty and cost of the cartridge stove.

[0007] One object of the present invention is to provide a gas stove, a stove system and a gas stove combustion method, wherein the gas stove's windproof device has windproof rings arranged around the burner head to prevent air outside the windproof ring from reaching the burner head laterally, thereby maintaining the stability of the flame formed above the burner head by burning mixed fuel in the gas stove.

[0008] One object of the present invention is to provide a cassette stove, a stove system and a combustion method for a cassette stove, wherein the cassette stove forms a guide channel between the top cover of the shell and the guide ring of the windproof device, and the guide channel is used to guide the air outside the windproof ring to the inside so that the mixed fuel can be fully burned.

[0009] One object of the present invention is to provide a gas stove, a stove system and a combustion method for a gas stove, wherein the height position of the inner opening of the guide channel is higher than the height position of the main body, so that the inner opening of the guide channel can face the combustion surface of the burner head, so that the air outside the windproof ring can be directly guided to the combustion surface of the burner head, which is crucial to ensure sufficient combustion of the fuel.

[0084] Reference Attachment Figures 1 to 27A stove system according to a preferred embodiment of the present invention will be disclosed and explained in the following description, wherein the stove system includes a cartridge stove 1000 and a valve body assembly 2000 connected to the cartridge stove 1000, wherein the valve body assembly 2000 can be installed on a gas tank 3000, wherein the valve body assembly 2000 is used to supply fuel (usually butane) stored in the gas tank 3000 to the cartridge stove 1000.

[0085] Reference Attachment Figures 2 to 27 The gas stove 1000 includes a shell 10, a premixing device 20, a nozzle 30, a burner head 40, an ignition device 50, a fuel pipeline 60 and a stopcock 70, wherein the premixing device 20 is installed in the shell 10, wherein the premixing device 20 has a premixing chamber 21 and a fuel inlet 22, a fuel outlet 23 and at least one air inlet 24 respectively connected to the premixing chamber 21, wherein the nozzle 30 is installed at the fuel inlet 22 of the premixing device 20, wherein the burner head 40 is installed at the fuel outlet 23 of the premixing device 20, and the burner head 40 is located at the top of the shell 10, wherein the ignition device 50 is arranged adjacent to the burner head 40, wherein opposite ends of the fuel pipeline 60 are connected to the nozzle 30 and the stopcock 70 respectively, and at least a portion of the fuel pipeline 60 is arranged adjacent to the burner head 40.

[0086] In the stove system of the present invention, the stopcock 70 of the gas stove 1000 is connected to the valve body assembly 2000, wherein the valve body assembly 2000 is used to control the state of the fuel stored in the gas tank 3000 being supplied toward the stopcock 70, and the stopcock 70 is used to control the state of the fuel being supplied toward the fuel pipeline 60.

[0087] When the valve body assembly 2000 and the stopcock 70 allow the gaseous fuel stored in the gas tank 3000 to be supplied toward the fuel pipeline 60, the fuel pipeline 60 allows the gaseous fuel to be sprayed into the premixing chamber 21 of the premixing device 20 through the nozzle 30. When the gaseous fuel is sprayed into the premixing chamber 21 of the premixing device 20 through the nozzle 30, the high-speed movement of the gaseous fuel causes a negative pressure environment to be formed in the premixing chamber 21 of the premixing device 20, so that air is sucked into the premixing chamber 21 through the air inlet 24 of the premixing device 20. The air sucked into the premixing chamber 21 of the premixing device 20 and the gaseous fuel sprayed into the premixing chamber 21 of the premixing device 20 are mixed to form a mixed fuel. Subsequently, the mixed fuel is supplied to the burner 40 through the fuel outlet 23 of the premixing device 20 and is ignited by the ignition device 50 to generate a flame when it is discharged from the combustion surface 41 of the burner 40. Since at least a portion of the fuel pipe 60 is disposed adjacent to the burner 40 , the flame generated by burning the gaseous fuel in the gas stove 1000 can heat the portion of the fuel pipe 60 adjacent to the burner 40 , thereby causing the portion of the fuel pipe 60 adjacent to the burner 40 to have a higher temperature.

[0088] When the valve body assembly 2000 and the stopcock 70 allow the liquid fuel stored in the gas tank 3000 to be supplied to the fuel pipe 60, the liquid fuel is heated and vaporized into gaseous fuel when flowing through the portion of the fuel pipe 60 adjacent to the burner 40. Then, the gaseous fuel is sprayed into the premixing chamber 21 of the premixing device 20 through the nozzle 30. When the gaseous fuel is sprayed into the premixing chamber 21 of the premixing device 20 through the nozzle 30, the high-speed moving gaseous fuel causes the premixing device 20 to A negative pressure environment is formed in the premixing chamber 21 of the premixing device 20, so that air is sucked into the premixing chamber 21 through the air inlet 24 of the premixing device 20, and the air sucked into the premixing chamber 21 of the premixing device 20 and the gaseous fuel sprayed into the premixing chamber 21 of the premixing device 20 are mixed to form a mixed fuel. Subsequently, the mixed fuel is supplied to the burner 40 through the fuel outlet 23 of the premixing device 20, and is ignited by the ignition device 50 to generate a flame when it is discharged from the combustion surface 41 of the burner 40.

[0089] Different from the prior art cartridge furnace, Figures 1 to 27In the stove system of the present invention shown, the cartridge stove 1000 does not require the gas tank 3000 to continuously supply gaseous fuel to the burner 40 through the valve body assembly 2000. After the cartridge stove 1000 generates a flame by igniting the gaseous fuel, the gas tank 3000 only needs to continuously supply liquid fuel to the fuel pipe 60 through the valve body assembly 2000. The liquid fuel entering the fuel pipe 60 can be heated and vaporized into gaseous fuel when it reaches the portion of the fuel pipe 60 adjacent to the burner 40. In this way, during the long-term use of the stove system, the temperature of the gas tank 3000 will not decrease, and the pressure in the gas tank 3000 will not decrease due to the increase in the time of outputting the liquid fuel. Therefore, the gas tank 3000 can continuously and stably output the liquid fuel to maintain the stability of the flame generated by the combustion of the fuel in the cartridge stove 1000, thereby achieving a power stability effect.

[0090] In other words, when the cartridge stove 1000 burns the liquid fuel output from the gas cylinder 3000 for a long time, the flame generated by the cartridge stove 1000 can remain stable, that is, the flame generated by the cartridge stove 1000 due to burning the fuel will not decrease as the time for the gas cylinder 3000 to output the liquid fuel increases, which is crucial for the user to use the stove system normally.

[0091] Continue to refer to the attached Figure 2 、 Figures 5 to 8 、 Figure 11 、 Figure 22 and Figure 23 The fuel pipeline 60 includes at least two low-level transmission sections 61, at least two connecting transmission sections 62, and at least one high-level transmission section 63, wherein one end of the connecting transmission section 62 extends upward to and is connected to the high-level transmission section 63, and the other end extends downward to and is connected to the low-level transmission section 61. One of these low-level transmission sections 61 is connected to the stopcock 70, and the other is connected to the nozzle 30. From a side view, the position of the low-level transmission section 61 is lower than the position of the burner 40, and the position of the high-level transmission section 63 is higher than the position of the burner 40. In this way, the high-level transmission section 63 of the fuel pipeline 60 is adjacent to the burner 40. In this way, the flame generated by the combustion of fuel in the gas stove 1000 can heat the high-level transmission section 63 of the fuel pipeline 60, so that when the liquid-phase fuel flows through the low-level transmission section 61 and the connecting transmission section 62 and the high-level transmission section 63, it can be heated and vaporized into gaseous fuel.

[0092] Specifically, refer to the attached Figures 14 to 23The combustion surface 41 of the burner 40 is an inclined combustion surface, the height position of the inner edge of the combustion surface 41 is higher than the height position of the outer edge, and the high-position transmission section 63 of the fuel pipeline 60 is located obliquely above the combustion surface 41 of the burner 40. From a side perspective, the height position of the high-position transmission section 63 of the fuel pipeline 60 is slightly higher than the height position of the inner edge of the combustion surface 41 of the burner 40. From a top perspective, the high-position transmission section 63 of the fuel pipeline 60 is located at the combustion surface 41 of the burner 40. The outside of the outer edge of the burning surface 41, and the high-level transmission section 63 of the fuel pipe 60 and the outer edge of the burning surface 41 of the burner 40 have a smaller distance, so that the high-level transmission section 63 of the fuel pipe 60 and the burner 40 are adjacent, so that the flame generated by the combustion of gaseous fuel in the gas-phase stove 1000 can heat the high-level transmission section 63 of the fuel pipe 60, so that when the liquid-phase fuel flows through the high-level transmission section 63 through the low-level transmission section 61 and the connecting transmission section 62, it can be heated and vaporized into gaseous fuel.

[0093] It is worth mentioning that the high-level transmission section 63 of the fuel pipeline 60 can be a straight pipe, a curved pipe, or a spiral pipe, which is designed according to needs.

[0094] Optionally, in other examples of the stove system of the present invention, from a side view, the high-level transmission section 63 of the fuel pipe 60 and the burner 40 have an overlapping portion, that is, the height position of the high-level transmission section 63 of the fuel pipe 60 is higher than the height position of the outer edge of the combustion surface 41 of the burner 40, and the height position of the high-level transmission section 63 of the fuel pipe 60 is lower than the height position of the inner edge of the combustion surface 41 of the burner 40. In this way, the flame generated by the combustion of gaseous fuel in the gas stove 1000 can heat the high-level transmission section 63 of the fuel pipe 60, so that when the liquid-phase fuel flows through the high-level transmission section 63 through the low-level transmission section 61 and the connecting transmission section 62, it can be heated and vaporized into gaseous fuel.

[0095] Continue to refer to the attached Figure 2 、 Figures 5 to 8 、 Figure 11 、 Figure 22 and Figure 23The fuel pipeline 60 includes two high-level transmission sections 63, each of which is located adjacent to the burner head 40. This allows the liquid fuel to be vaporized twice during its transmission through the fuel pipeline 60 toward the nozzle 30, converting the entire liquid fuel into vaporous fuel, thereby improving fuel efficiency. Preferably, the two high-level transmission sections 63 of the fuel pipeline 60 are positioned symmetrically relative to the burner head 40.

[0096] It is worth mentioning that the positions of the two high-level transmission sections 63 of the fuel pipeline 60 are symmetrical relative to the burner head 40, and it is not required that the states (for example, shape, size) of the two high-level transmission sections 63 themselves are symmetrical relative to the burner head 40, as long as the positions of the two high-level transmission sections 63 are symmetrical relative to the burner head 40.

[0097] Specifically, the number of the low-level transmission sections 61 of the fuel pipeline 60 is three, which are defined in sequence as a first low-level transmission pipe 611, a second low-level transmission pipe 612 and a third low-level transmission pipe 613; the number of the connecting transmission sections 62 is four, which are defined in sequence as a first connecting transmission pipe 621, a second connecting transmission pipe 622, a third connecting transmission pipe 623 and a fourth connecting transmission pipe 624; the number of the high-level transmission sections 63 is two, which are defined in sequence as a first high-level transmission pipe 631 and a second high-level transmission pipe 632. One end of the first low-level transmission pipe 611 is connected to the stopcock 70, the first connecting transmission pipe 621 extends upward from the other end of the first low-level transmission pipe 611 to and is connected to one end of the first high-level transmission pipe 631, the second connecting transmission pipe 622 extends downward from the other end of the first high-level transmission pipe 631 to and is connected to one end of the second low-level transmission pipe 612, and the third connecting transmission pipe 623 extends upward from the other end of the second low-level transmission pipe 612 to and is connected to one end of the second high-level transmission pipe 632. end, the fourth connecting transmission pipe 624 extends downward from the other end of the second high-level transmission pipe 632 to and is connected to one end of the third low-level transmission pipe 613, and the other end of the third low-level transmission pipe 613 is connected to the nozzle 30, so that the first connecting transmission pipe 621 and the second connecting transmission pipe 622 can support the first high-level transmission pipe 631 to a position adjacent to the burner head 40, and the third connecting transmission pipe 623 and the fourth connecting transmission pipe 624 can support the second high-level transmission pipe 632 to a position adjacent to the burner head 40.

[0098] It can be understood that the height of the first high-level transmission pipe 631 is related to the lengths of the first connecting transmission pipe 621 and the second connecting transmission pipe 622. The longer the lengths of the first connecting transmission pipe 621 and the second connecting transmission pipe 622, the higher the position of the first high-level transmission pipe 631. Correspondingly, the height of the second high-level transmission pipe 632 is related to the lengths of the third connecting transmission pipe 623 and the fourth connecting transmission pipe 624. The longer the lengths of the third connecting transmission pipe 623 and the fourth connecting transmission pipe 624, the higher the position of the second high-level transmission pipe 632.

[0099] Attachment Figure 27 A modified example of the cartridge stove 1000 is shown. Figures 1 to 27 The difference between the illustrated cartridge stove 1000 and the attached Figure 28 In this specific example of the gas stove 1000 shown, the number of the low-level transmission sections 61 of the fuel pipeline 60 is two, which are the first low-level transmission pipe 611 and the second low-level transmission pipe 612 respectively, the number of the connecting transmission sections 62 is two, which are the first connecting transmission pipe 621 and the second connecting transmission pipe 622 respectively, and the number of the high-level transmission sections 63 is one. One end of the first low-level transmission pipe 611 is connected to the ball valve 70, the first connecting transmission pipe 621 extends upward from the other end of the first low-level transmission pipe 611 to and is connected to one end of the high-level transmission section 63, the second connecting transmission pipe 622 extends downward from the other end of the high-level transmission section 63 to and is connected to one end of the second low-level transmission pipe 612, the other end of the second low-level transmission pipe 612 is connected to the nozzle 30, and the high-level transmission section 63 extends in a curved manner to the outside of the burner 40 so that the high-level transmission section 63 has a sufficient length. In this way, the liquid-phase fuel can be fully vaporized during the process of being transmitted through the fuel pipeline 60 toward the nozzle 30, so that the liquid-phase fuel can be completely converted into gaseous fuel, thereby achieving a power stability effect.

[0100] Continue to refer to the attached Figures 1 to 27 The shell 10 includes a shell body 11 and a top cover 12, and the shell 10 has a receiving space 13. The top cover 12 is installed on the top of the shell body 11, and the receiving space 13 is formed between the top cover 12 and the shell body 111.

[0101] It is worth mentioning that the specific shapes of the shell body 11 and the top cover 12 are not limited in the stove system of the present invention, but it should be noted that the shapes of the shell body 11 and the top cover 12 determine the general appearance of the gas stove 1000 of the stove system. Figures 1 to 27 In this specific example of the stove system of the present invention, the shell body 11 and the top cover 12 are both square (eg, rectangular or square), and the size of the shell body 11 matches the size of the top cover 12, so that the gas stove 1000 is square.

[0102] Reference Attachment Figures 2 to 27 The shell body 11 further includes a bottom plate 111, four support columns 112 and four side panels 113, the bottom of each support column 112 extends downward to and is fixedly installed on each corner of the bottom plate 111, the top of each support column 112 extends upward to and is fixedly installed on each corner of the top cover 12, these side panels 113 surround the outside of these support columns 112 end to end, and the bottom of each side panel 113 abuts against the side of each corresponding position of the bottom plate 111, and the top of each side panel 113 abuts against the side of each corresponding position of the top cover 12, so that the shell 10 forms the receiving space 13 between the bottom plate 111, the four side panels 113 and the top cover 12.

[0103] Furthermore, the shell body 11 includes four bottom locking elements 114, one end of each bottom locking element 114 is screwed to the bottom of each support column 112 after passing through each corner of the bottom plate 111, so as to fix the bottom of each support column 112 at each corner of the bottom plate 111, and the other end of each bottom locking element 114 protrudes from the bottom of the bottom plate 111, so that when the gas stove 1000 is supported on a supporting surface (for example, the ground or a table), these bottom locking elements 114 keep the bottom plate 111 away from the supporting surface. In this way, the heat generated by the cartridge stove 1000 when burning fuel can be quickly radiated to the outside of the cartridge stove 1000 through the bottom plate through holes 1111 of the bottom plate 111, so as to reduce the temperature of the cartridge stove 1000, which is crucial for ensuring the safety of users when using the cartridge stove 1000. At the same time, the bottom plate through holes 1111 of the bottom plate 111 allow air from the external environment to enter the receiving space 13 of the shell 10, so that the receiving space 13 of the shell 10 has sufficient air to enter the premixing chamber 21 through the air inlet 24 of the premixing device 20.

[0104] Correspondingly, the shell body 11 further includes four top locking elements 115, and one end of each top locking element 115 is screwed to the top of each support column 112 after passing through each corner of the bottom plate 111, so as to fixedly install the top of each support column 112 at each corner of the top cover 12.

[0123] Specifically, the assembly device 100 includes a first assembly body 101 and a nut 102, wherein the first assembly body 101 includes an assembly seat 1011 and an assembly column 1012 extending upward from the assembly seat 1011 as a whole, and a first assembly body through-hole 1013 passing through the assembly seat 1011 and the assembly column 1012, the cross-sectional size of the assembly seat 1011 is larger than the size of the middle through-hole 125 of the top cover 12, the cross-sectional size of the assembly column 1012 is smaller than or equal to the size of the middle through-hole 125 of the top cover 12, and the assembly The column 1012 is screwed onto the nut 102 after extending from the receiving space 13 of the shell 10 to the upper portion of the top cover 12 through the central through-hole 125 of the top cover 12, so that the assembly device 100 is fixedly assembled to the central through-hole 125 of the top cover 12, wherein the end of the longitudinally extending portion 26 of the premixing device 20 for forming the fuel outlet 23 is fixedly assembled to the first assembly body 101, and the fuel outlet 23 of the premixing device 20 is communicated with the first assembly body through-hole 1013 of the first assembly body 101.

[0124] It is worth mentioning that the fixing and assembling method of the end portion of the longitudinal extension portion 26 of the premixing device 20 for forming the fuel outlet 23 and the first assembly body 101 is not limited in the stove system of the present invention. For example, in this specific example of the stove system of the present invention, referring to Figure 6 、 Figures 14 to 21 The outer wall of the end portion of the longitudinally extending portion 26 of the premixing device 20, which is used to form the fuel outlet 23, and the inner wall of the first assembly body 101 are engaged with each other to fixedly assemble the end portion of the longitudinally extending portion 26 of the premixing device 20, which is used to form the fuel outlet 23, to the first assembly body 101 and ensure sealing between the two to prevent the mixed fuel in the premixing chamber 21 of the premixing device 20 from leaking through the junction between the end portion of the longitudinally extending portion 26 of the premixing device 20, which is used to form the fuel outlet 23, and the first assembly body 101.

[0126] It is worth mentioning that the fixing and assembling method of the extension column 1032 of the second assembly body 103 and the assembly column 1012 of the first assembly body 101 is not limited in the stove system of the present invention. For example, in this specific example of the stove system of the present invention, referring to Figure 6 、 Figures 14 to 21 The outer wall of the extension column 1032 of the second assembly body 103 and the inner wall of the assembly column 1012 of the first assembly body 101 are engaged with each other to fixedly assemble the extension column 1032 of the second assembly body 103 to the assembly column 1012 of the first assembly body 101 and ensure the sealing between the two to prevent the mixed fuel in the premixing chamber 21 of the premixing device 20 from leaking through the joint position between the assembly column 1012 of the first assembly body 101 and the extension column 1032 of the second assembly body 103.

[0127] That is, in the stove system of the present invention, the first fixing device 90 is used to reliably fix the transversely extending portion 25 of the premixing device 20 to the bottom plate 111, and the assembly device 100 is used to reliably fix the longitudinally extending portion 26 of the premixing device 20 to the top cover 12. Since the top cover 12 and the bottom plate 111 are connected by the multiple support columns 112 and the multiple side plates 113, the relative positions of the top cover 12 and the bottom plate 111 remain unchanged, so that the premixing device 20 can be reliably and stably accommodated in the accommodating space 13 of the shell 10.

[0128] Continue to refer to the attached Figure 2 、 Figures 5 to 7 、 Figure 14 and Figure 15The burner 40 includes a burner bottom plate 42 and a burner top plate 43 and a distribution space 44, wherein the burner bottom plate 42 includes a bottom plate center portion 421 and a bottom plate peripheral portion 422 extending outward and downward from the bottom plate center portion 421, and the bottom plate center portion 421 has a bottom plate through-hole 4211, wherein the burner top plate 43 includes a top plate center portion 431 and a top plate peripheral portion 432 extending outward and downward from the top plate center portion 431, and the top plate peripheral portion 432 has a group of top plate through-holes 4321. The burning surface of the burner 40 41 is formed in the top plate peripheral portion 432, wherein the outer edge of the bottom plate peripheral portion 422 of the burner bottom plate 42 and the outer edge of the top plate peripheral portion 432 of the burner top plate 43 are sealedly connected, the position of the top plate center portion 431 corresponds to the position of the bottom plate center portion 421, the bottom plate through-hole 4211 of the bottom plate center portion 421 is connected to the distribution space 44, the position of the top plate peripheral portion 432 corresponds to the position of the bottom plate peripheral portion 422, and the top plate through-hole 4321 of the top plate peripheral portion 432 is connected to the distribution space 44.

[0129] It is worth mentioning that the manner in which the outer edge of the bottom plate peripheral portion 422 of the stove bottom plate 42 and the outer edge of the top plate peripheral portion 432 of the stove top plate 43 are sealed and connected is not limited in the stove system of the present invention. Figures 1 to 27 In this specific example of the stove system of the present invention, the outer edge of the top plate peripheral portion 432 of the burner top plate 43 can wrap around the outer edge of the bottom plate peripheral portion 422 of the burner bottom plate 42 in a manner of bending inward and extending around the outer edge of the bottom plate peripheral portion 422, so that the outer edge of the bottom plate peripheral portion 422 of the burner bottom plate 42 and the outer edge of the top plate peripheral portion 432 of the burner top plate 43 are sealed and connected, thereby preventing the mixed fuel entering the distribution space 44 of the burner 40 from leaking at this position.

[0130] When the burner 40 is mounted on the second assembly body 103 of the assembly device 100, the retaining posts 1033 of the second assembly body 103 extend through the bottom plate through-holes 4211 of the bottom plate center portion 421 of the burner bottom plate 42 to the distribution space 44 of the burner 40. The bottom plate center portion 421 is supported by the support seat 1031 of the second assembly body 103. The second assembly body through-holes 1034 of the second assembly body 103 communicate with the distribution space 44 of the burner 40, allowing mixed fuel to enter the distribution space 44 of the burner 40 through the assembly device 100. It is understood that the mixed fuel entering the distribution space 44 of the burner 40 can be relatively evenly distributed and discharged from the burner 40 through the top plate through-holes 4311 of the top plate peripheral portion 432 of the burner top plate 43.

[0131] Preferably, the size and shape of the chassis through-hole 4211 in the chassis center portion 421 of the burner chassis 42 are consistent with the size and shape of the retaining column 1033 of the second assembly 103, so that the burner 40 can be securely assembled to the second assembly 103 under its own weight. In this way, not only can the burner 40 be prevented from shaking, but also the mixed fuel can be prevented from leaking from the junction between the burner 40 and the second assembly 103. Optionally, in other examples of the stove system of the present invention, after the top of the second assembly 103 passes through the chassis through-hole 4211 in the chassis center portion 421 of the burner chassis 42, the portion of the top of the second assembly 103 that passes through the chassis through-hole 4211 in the chassis center portion 421 is folded to securely assemble the burner chassis 42 and the second assembly 103.

[0132] Furthermore, the burner head 40 includes a metal mesh 45, which is attached to the top plate peripheral portion 432 of the burner head top plate 43 in a manner of being located in the distribution space 44. The metal mesh 45 can effectively prevent tempering to improve the safety and reliability of the stove system.

[0133] It is worth mentioning that the specific manner in which the metal mesh 45 is attached to the top plate peripheral portion 432 of the stove top plate 43 is not limited in the stove system of the present invention. Figures 1 to 27In this specific example of the stove system of the present invention, the shape and size of the main part of the metal mesh 45 match the shape and size of the inner wall of the top plate peripheral part 432, the two can be welded, and the outer edge of the metal mesh 45 is overlapped with the outer edge of the bottom plate peripheral part 422 of the burner bottom plate 42, and the outer edge of the top plate peripheral part 432 of the burner top plate 43 can wrap the outer edge of the metal mesh 45 and the outer edge of the bottom plate peripheral part 422 in a manner of bending inward and extending after bypassing the outer edge of the metal mesh 45 and the outer edge of the bottom plate peripheral part 422 of the burner bottom plate 42, thereby ensuring the reliability and stability of the burner 40.

[0134] Continue to refer to the attached Figure 2 、 Figure 5 、 Figure 6 and Figure 18 The ignition device 50 is disposed on the top cover 12 of the housing 10. The top cover 12 positions the ignition device 50 adjacent to the burner 40. Thus, when the mixed fuel is discharged through the top plate through-holes 4321 of the top plate peripheral portion 432 of the burner top plate 43 of the burner 40, the ignition device 50 can ignite the mixed fuel, causing the gas stove 1000 to produce a flame. In this specific example of the stove system of the present invention, the ignition device 50 may be an electric ignition device.

[0135] Specifically, the top cover 12 has a hollow opening 126, which communicates with the receiving space 13 of the housing 10 and is adjacent to the central through-hole 125. The main body of the ignition device 50 is received in the receiving space 13 of the housing 10, and the ignition head 51 of the ignition device 50 extends through the hollow opening 126 of the top cover 12 to the top of the top cover 12, thereby placing the ignition device 50 on the top cover 12. Because the central through-hole 125 and the hollow opening 126 of the top cover 12 are adjacent, the ignition head 51 of the ignition device 50 and the burner 40 are adjacent.

[0136] Further, please refer to the attached Figure 2 、 Figure 5 、 Figure 6 and Figure 18The gas stove 1000 includes a shielding device 110 , wherein the shielding device 110 further includes a first shielding wall 1101 , a second shielding wall 1102 , a third shielding wall 1103 , a fourth shielding wall 1104 and an assembly plate 1105 . The assembly plate 1105 has an assembly end 11051 and a blocking end 11052 corresponding to the assembly end 11051, and the assembly plate 1105 is provided with an assembly channel 11053 at the assembly end 11051 and a plate channel 11054 at the blocking end 11052, wherein the assembly plate 1105 is clamped between the supporting seat 1031 of the second assembly body 103 and the assembly column 1012 of the first assembly body 101 in such a manner that the extension column 1032 of the second assembly body 103 passes through the assembly channel 11053 of the assembly plate 1105, so that the assembly plate 1105 is suspended above the top cover 12 by the assembly device 100. The first shielding wall 1101 integrally extends upward from the end of the shielding end 11052 of the assembly plate 1105, the second shielding wall 1102 integrally extends from the top of the first shielding wall 1101 toward the assembly end 11051 of the assembly plate 1105, the third shielding wall 1103 integrally extends upward from one side of the shielding end 11052 of the assembly plate 1105 to a position adjacent to one side of the second shielding wall 1102, and the fourth shielding wall 1104 integrally extends upward from the other side of the shielding end 11052 of the assembly plate 1105 to a position adjacent to the other side of the second shielding wall 1102. It is arranged to form a shielding space 1106 between the first shielding wall 1101, the second shielding wall 1102, the third shielding wall 1103, the fourth shielding wall 1104 and the assembly plate 1105, and an ignition port 1107 connected to the shielding space 1106 is formed between the second shielding wall 1102, the third shielding wall 1103, the fourth shielding wall 1104 and the assembly plate 1105, and the ignition port 1107 faces the combustion surface 41 of the burner head 40, wherein the plate channel 11054 of the assembly plate 1105 is connected to the shielding space 1106 and corresponds to the second shielding wall 1102.

[0137] The position of the plate channel 11054 of the assembly plate 1105 corresponds to the position of the hollow opening 126 of the top cover 12, so that the ignition head 51 of the ignition device 50 extends to the shielding space 1106 through the hollow opening 126 of the top cover 12 and the plate channel 11054 of the assembly plate 1105 in sequence, and the second shielding wall 1102 is located directly above the ignition head 51 of the ignition device 50, so that the shielding device 110 limits the direction of the spark generated by the ignition head 51 of the ignition device 50, so that the ignition device 50 can smoothly ignite the mixed fuel discharged through the top plate through-hole 432 of the top plate peripheral portion 432 of the burner top plate 43 of the burner 40.

[0138] Preferably, the shielding device 110 is a sheet metal part, which is formed by punching at a preset position and bending at a preset position to form the first shielding wall 1101, the second shielding wall 1102, the third shielding wall 1103, the fourth shielding wall 1104 and the assembly plate 1105, as well as the assembly channel 11053 and the plate channel 11054.

[0139] Continue to refer to the attached Figure 2 、 Figures 5 to 7 、 Figures 14 to 23 The top cover 12 has at least one pipe through-hole 127, and the pipe through-hole 127 is connected to the receiving space 13 of the shell 10, wherein the low-position transmission section 61 of the fuel pipe 60 is received in the receiving space 13 of the shell 10, and the connecting transmission section 62 extends to the top of the top cover 12 through the pipe through-hole 127 of the top cover 12 to support the high-position transmission section 63 above the top cover 12, so that the high-position transmission section 63 of the fuel pipe 60 is arranged at a position adjacent to the burner 40, so that when the liquid-phase fuel flows through the high-position transmission section 63 of the fuel pipe 60, it can be heated and vaporized into gaseous-phase fuel.

[0140] Preferably, the number of the pipe perforations 127 of the top cover 12 is two, and the two pipe perforations 127 are symmetrically arranged adjacent to each other on opposite sides of the middle perforation 125, wherein the first connecting transmission pipe 621 and the second connecting transmission pipe 622 of the fuel pipeline 60 extend to the top of the top cover 12 through one of the pipe perforations 127 of the top cover 12, so that the first high-level transmission pipe 631 is set at a position adjacent to one side of the burner 40 by the first connecting transmission pipe 621 and the second connecting transmission pipe 622, wherein the third connecting transmission pipe 623 and the fourth connecting transmission pipe 624 of the fuel pipeline 60 extend to the top of the top cover 12 through another pipe perforation 127 of the top cover 12, so that the second high-level transmission pipe 632 is set at a position adjacent to the other side of the burner 40 by the third connecting transmission pipe 623 and the fourth connecting transmission pipe 624. It can be understood that since the two pipe perforations 127 of the top cover 12 are symmetrical with respect to the middle perforation 125, the position of the first high-level transmission pipe 631 and the position of the second high-level transmission pipe 632 of the fuel pipeline 60 are symmetrical with respect to the burner head 40.

[0141] Continue to refer to the attached Figure 2 、 Figure 22 and Figure 23 The gas stove 1000 further includes a second fixing device 120. The second fixing device 120 is disposed on the bottom plate 111 of the shell body 11 so as to be accommodated in the accommodation space 13 of the shell 10 and adjacent to the first fixing device 90. The low-position transmission section 61 of the fuel pipe 60 is disposed on the second fixing device 120. In this way, the first fixing device 90 and the second fixing device 120 cooperate with each other to ensure that the low-position transmission section 61 of the fuel pipe 60 is securely accommodated in the accommodation space 13 of the shell 10. Preferably, the first fixing device 90 and the second fixing device 120 are fixedly connected.

[0142] Continue to refer to the attached Figure 2 、 Figure 3 、 Figure 6 、 Figure 7 、 Figures 14 to 23The gas stove 1000 further includes a connecting device 130 having a first connecting end 1301 and a second connecting end 1302 corresponding to the first connecting end 1301.

Preferably, the connecting device 130 has an avoidance channel 1303 for avoiding the assembly device 100.

[0143] Preferably, the second connecting end 1302 of the connecting device 130 is further connected to the low-level transmission section 61 of the fuel pipeline 60. Specifically, the connecting device 130 further has at least one snap-fitting groove 1304, which is provided on the second connecting end 1302. The low-level transmission section 61 is snapped into the snap-fitting groove 1304 of the connecting device 130, so that the second connecting end 1302 of the connecting device 130 is used to connect to the low-level transmission section 61.

[0144] Continue to refer to the attached Figure 1 、 Figure 2 、 Figures 5 to 8 、 Figure 11 、 Figures 14 to 18 The cartridge stove 1000 further includes a windproof device 140, and the windproof device 140 includes a windproof ring 1401, wherein the windproof ring 1401 is arranged above the shell 10 in a manner of surrounding the burner 40, wherein from a side view, the windproof ring 1401 is higher than the combustion surface 41 of the burner 40. In this way, when the cartridge stove 1000 burns the mixed fuel discharged from the burner 40, the windproof ring 1401 is used to prevent the wind from reaching the combustion surface 41 of the burner 40 laterally, so as to ensure the stability of the flame.

[0145] Continue to refer to the attached Figure 1 、 Figure 2 、 Figures 5 to 8 、 Figure 11 、 Figures 14 to 18The windproof device 140 further includes a guide ring 1402, which extends inward from the bottom of the windproof ring 1401 to an appropriate position, wherein the gas stove 1000 forms a guide channel 150 between the guide ring 1402 and the top cover 12, and the guide channel 150 connects the inner and outer sides of the windproof ring 1401. The guide channel 150 is used to guide the air located on the outside of the windproof ring 1401 to enter the inner side of the windproof ring 1401 at a specific position, so as to allow the mixed fuel discharged from the burner head 40 to be fully burned.

[0146] It is worth mentioning that the specific manner in which the guide channel 150 is formed between the guide ring 1402 and the top cover 12 of the gas stove 1000 is not limited in the stove system of the present invention. For example, the gas stove 1000 further includes a plurality of locking devices 160, each of which includes a locking rod 1601 and a locking ring 1602. The locking ring 1602 is arranged between the guide ring 1402 and the top cover 12, and the top of the locking ring 1602 corresponds to the first locking hole 14021 of the guide ring 1402, and the bottom of the locking ring 1602 corresponds to the second locking hole 128 of the top cover 12. One end of the locking rod 1601 is locked to the top cover 12 after passing through the first locking hole 14021 of the guide ring 1402, the locking ring 1602 and the second locking hole 128 of the top cover 12 in sequence. In this way, the locking device 160 ensures that the windproof device 140 is arranged above the top cover 12, and forms the guide channel 150 between the guide ring 1402 and the top cover 12. Preferably, the locking ring 1602 is screwed onto the locking rod 1601 to fix the locking device 160 on the windproof device 140 .

[0147] It can be understood that the flow rate of the guide channel 150 is related to the height dimension of the guide channel 150, and the height dimension of the guide channel 150 is related to the height dimension of the locking ring 1602. The higher the height dimension of the locking ring 1602, the higher the height dimension of the guide channel 150, and accordingly, the greater the flow rate of the guide channel 150. Therefore, the flow rate of the guide channel 150 can be adjusted by changing the height dimension of the locking ring 1602 to meet the use needs of the gas stove 1000 in different scenarios.

[0148] It is worth mentioning that the manner in which the locking rod 1601 of the locking device 160 is locked to the top cover 12 is not limited in the stove system of the present invention. Figures 1 to 27In this specific example of the stove system of the present invention, the bottom of the locking rod 1601 can be directly inserted into the second locking hole 128 of the top cover 12 , so that the locking rod 1601 is locked to the top cover 12 .

[0149] Preferably, the height position of the inner opening of the guide channel 150 is higher than the height position of the main body, so as to allow the inner opening of the guide channel 150 to face the combustion surface 41 of the burner 40, so that the air introduced by the guide channel 150 can directly reach the combustion surface 41 of the burner 40, thereby allowing the mixed fuel discharged from the burner 40 to be fully burned.

[0150] Specifically, the top cover 12 has a bottom guide surface 129 inclined upward, and the guide ring 1402 has a top guide surface 14022 extending inclined upward, and the top guide surface 14022 of the guide ring 1402 is located above the bottom guide surface 129 of the top cover 12, and the inner opening of the guide channel 150 is formed between the top guide surface 14022 of the guide ring 1402 and the bottom guide surface 129 of the top cover 12.

[0151] Preferably, continue to refer to the attached Figure 14 and Figure 15 The size of the inner opening of the guide channel 150 is smaller than that of the main body, so that the flow rate of air at the inner opening of the guide channel 150 is smaller than that of the main body. This can increase the flow rate of the air guided by the guide channel 150, so that the introduced air reaches the combustion surface 41 of the burner 40 in a jet manner, thereby allowing the mixed fuel discharged from the burner 40 to be fully burned.

[0152] Specifically, the inner edge of the guide ring 1402 extends downward and then outward, so that the size of the inner opening of the guide channel 150 is smaller than the size of the main body, so that the air flow at the inner opening of the guide channel 150 is smaller than the flow of the main body, and the guide ring 1402 is not easily deformed.

[0153] Reference Attachment Figure 1The valve body assembly 2000 further includes a valve body 2100 and a bracket 2200 disposed on the valve body 2100. The bracket 2200 has two support portions 2210 located on opposite sides of the valve body 2100. The plug valve 70 of the gas stove 1000 is connected to the valve body 2100. For example, the stove system has a connecting pipe 4000, the opposite ends of which are respectively connected to the plug valve 70 and the valve body 2100, so that the plug valve 70 is connected to the valve body 2100. After the valve body 2100 is mounted on the gas cylinder 3000, each support portion 2210 of the bracket 2200 can independently support the gas cylinder 3000 at a specific angle on a supporting surface.

[0154] Continue to refer to the attached Figure 1 、 Figure 2 、 Figures 5 to 8 、 Figure 11 The gas stove 1000 further includes a cooking utensil rack 170, comprising a frame 1701 and at least one leg 1702 integrally extending downward from the frame 1701. The leg 1702 is disposed on the top cover 12 of the housing 10. The frame 1702 is located above the burner 40, wherein the cooking utensil can be supported by the cooking utensil rack 170 above the burner 40. Preferably, the cooking utensil rack 170 includes four legs 1702, each of which is mounted in a mounting slot 1151 of each of the top locking elements 115, so that the cooking utensil rack 170 is securely mounted to the top cover 12 by the top locking elements 115.

[0155] Attachment Figure 26 and Figure 27The figure shows the process of using the stove system. Specifically, in the first stage of using the stove system, the valve body assembly 2000 is supported on a supporting surface with the inlet end of the valve tube 3100 of the gas cylinder 3000 facing upward. The valve body 2100 of the valve body assembly 2000 and the stopcock 70 of the gas stove 1000 allow the gaseous fuel in the gas cylinder 3000 to enter the fuel pipe 60 and be sprayed into the premixing chamber 21 of the premixing device 20 through the nozzle 30. When the gaseous fuel is sprayed into the premixing chamber 21 of the premixing device 20 through the nozzle 30, the high-speed The moving gaseous fuel creates a negative pressure environment within the premixing chamber 21 of the premixing device 20, causing air to be drawn into the premixing chamber 21 through the air inlet 24 of the premixing device 20. The air drawn into the premixing chamber 21 of the premixing device 20 mixes with the gaseous fuel injected into the premixing chamber 21 of the premixing device 20 to form a mixed fuel. Subsequently, the mixed fuel is supplied to the burner 40 through the fuel outlet 23 of the premixing device 20 and ignited by the ignition device 50 upon exiting the combustion surface 41 of the burner 40, generating a flame. During this process, because the high-level transmission section 63 of the fuel pipeline 60 is located adjacent to the burner 40, the flame generated by the combustion of the gaseous fuel in the gas stove 1000 can heat the high-level transmission section 63 of the fuel pipeline 60, thereby causing the high-level transmission section 63 of the fuel pipeline 60 to have a higher temperature.

[0156] In the second stage of use of the stove system, the valve body assembly 2000 is supported on a supporting surface with the inlet end of the valve tube 3100 of the gas tank 3000 facing downward, and the valve body 2100 of the valve body assembly 2000 and the stopcock 70 of the gas stove 1000 allow the liquid fuel in the gas tank 3000 to enter the fuel pipeline 60. The liquid fuel is heated and vaporized into gaseous fuel when flowing through the high-position transmission section 63 of the fuel pipeline 60. Then, the gaseous fuel is sprayed into the premixing chamber 21 of the premixing device 20 through the nozzle 30, and the gaseous fuel is sprayed into the premixing chamber 21 of the premixing device 20 through the nozzle 30. When the premixing chamber 21 of the premixing device 20 is opened, the high-speed moving gaseous fuel forms a negative pressure environment in the premixing chamber 21 of the premixing device 20, so that air is sucked into the premixing chamber 21 through the air inlet 24 of the premixing device 20, and the air sucked into the premixing chamber 21 of the premixing device 20 and the gaseous fuel injected into the premixing chamber 21 of the premixing device 20 are mixed to form a mixed fuel. Subsequently, the mixed fuel is supplied to the burner 40 through the fuel outlet 23 of the premixing device 20, and is ignited by the ignition device 50 to generate a flame when it is discharged from the combustion surface 41 of the burner 40.

[0158] (a) allowing gaseous fuel to be supplied to the burner 40 through the fuel pipe 60 and the premixing device 20 for subsequent combustion;

[0159] (b) allowing heat generated by combustion of the gaseous fuel to heat at least a portion of the fuel conduit 60; and

[0160] (c) The heated portion of the fuel pipe 60 is allowed to vaporize the liquid fuel transported toward the premixing device 20 .

[0161] In step (b), the gaseous fuel is allowed to heat the high-level transmission section 63 of the fuel pipeline 60 during combustion, so that in step (c), when the liquid-phase fuel is transmitted through the high-level transmission section 63, it is vaporized to form gaseous fuel, wherein from a side view, the high-level transmission section 63 and the burner head 40 have an overlapping portion, or the position of the high-level transmission section 63 is higher than that of the burner head 40.

[0162] Preferably, the combustion method further comprises the step of: (d) preventing external air from reaching the combustion surface 41 of the burner head 40 laterally by the windproof ring 1401 of the windproof device 140 surrounding the burner head 40 .

[0163] Preferably, the combustion method further includes the step of: (e) guiding the air outside the windproof ring 1401 from the obliquely lower side of the burner head 40 to the combustion surface 41 of the burner head 40 through the guide channel 150 formed between the top cover 12 of the shell 10 and the guide ring 1402 of the windproof device 140.

[0164] Before step (a), the gas tank 3000 mounted on the valve body assembly 2000 is placed in a manner that the inlet end of the valve tube 3100 of the gas tank 3000 faces upward, so that the gaseous fuel in the gas tank 3000 is supplied to the burner 40 through the valve body 2100, the fuel pipeline 60 and the premixing device 20 for subsequent combustion, wherein after step (b), the gas tank 3000 is placed in a manner that allows the inlet end of the valve tube 3100 of the gas tank 3000 to face downward, so that the liquid fuel in the gas tank 3000 is supplied through the valve body 2100 and the fuel pipeline 60.
