DETAILED DESCRIPTION

[0032] The present invention is further described below in conjunction with embodiments, which are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, other embodiments obtained by ordinary technicians in the field without creative work are all within the scope of protection of the present invention.

[0033] See the instruction manual Figure 1-4 , this embodiment discloses a cup-type oil and gas controller for a liquid fuel stove, comprising a cup body assembly 4 and a cup cover assembly 1 connected to the cup body assembly 4 in a detachable connection manner;

[0034] Among them, the cup body assembly 4 includes a cup body 5, an air circuit assembly 6 and an oil circuit assembly 15, a filter screen 7 is arranged in the cup body 5, the air circuit assembly 6 includes an adjusting rod Ⅰ10 and a "T"-shaped air pipe 11, the air pipe 11 has an air inlet 12, an air outlet 13 and an adjusting port Ⅰ14, the air inlet 12, the air outlet 13 and the adjusting port Ⅰ14 are connected to each other, the air pipe 11 has a conical cavity Ⅰ, the large end of the conical cavity Ⅰ is connected to the adjusting port Ⅰ14, the small end is connected to the air outlet 13, the air inlet 12 is connected to the side wall of the conical cavity Ⅰ, one end of the adjusting rod Ⅰ10 has a conical portion Ⅰ that can cooperate with the conical cavity Ⅰ, the adjusting rod Ⅰ10 is arranged in the adjusting port Ⅰ14 by a thread, and the adjusting rod Ⅰ10 can enter and exit the adjusting port Ⅰ14 after rotating the adjusting rod Ⅰ10, thereby realizing the adjustment of the air volume;

[0035] The oil circuit assembly 15 includes an adjusting rod Ⅱ16 and an oil pipe 17 in a "I"-shaped structure. The oil pipe 17 has an oil inlet 18, an oil outlet 19 and an adjusting port Ⅱ1901. The oil inlet 18, the oil outlet 19 and the adjusting port Ⅱ1901 are connected to each other. The oil pipe 17 has a tapered cavity Ⅱ21. The large end of the tapered cavity Ⅱ21 is connected to the adjusting port Ⅱ1901, and the small end is connected to the oil outlet 19. The oil inlet 18 is connected to the side wall of the tapered cavity Ⅱ21. One end of the adjusting rod Ⅱ16 has a tapered portion Ⅱ22 that can cooperate with the tapered cavity Ⅱ21. The adjusting rod Ⅱ16 is arranged in the adjusting port Ⅱ1901 through a thread. After the adjusting rod Ⅱ16 is rotated, the adjusting rod Ⅱ16 can enter and exit the adjusting port Ⅱ1901, thereby realizing the adjustment of the oil amount.

[0036] The air pipe 11 and the oil pipe 17 are connected to the lower end of the cup body 5, and the oil inlet 18 provided on the oil pipe 17 is connected to the cup body 5. The axis of the regulating port Ⅰ14 of the air pipe 11 and the axis of the regulating port Ⅱ1901 of the oil circuit are parallel to each other; the regulating rod Ⅰ10 and the regulating rod Ⅱ16 are connected by a linkage assembly 23;

[0037] The oil pipe 17 and the air pipe 11 are integrally formed with the cup body 5 .

[0038] In this embodiment, the cup cover assembly 1 includes a cover body 2 and a solenoid valve body 3. The solenoid valve body 3 passes through the cover body 2 and is fixedly connected to the cover body 2. The feed port 37 of the solenoid valve body 3 extends out of the cover body 2, and the discharge port 38 of the solenoid valve body 3 is located inside the cover body 2.

[0039] Thus, in actual use, by rotating the adjusting rod Ⅰ10, the adjusting rod Ⅰ10 can enter and exit the adjusting port Ⅰ14, so that the conical portion Ⅰ provided on the adjusting rod Ⅰ10 cooperates with the conical cavity Ⅰ to adjust the gas volume of the gas outlet 13;

[0040] Similarly, the oil volume of the oil outlet 19 can be adjusted by adjusting the adjusting rod II 16; and the linkage control of the gas output and the oil output is realized by setting the linkage component 23 interface, so that the purpose of oil-gas linkage control can be achieved in actual use.

[0041] In actual use, the air inlet 12 is used to connect to the air booster, and the air outlet 13 is used to connect to the air path in the oil and gas two-fluid nozzle in the combustion system; the feed port 37 of the solenoid valve body 3 is used to connect to the methyl ester fuel source, and the oil outlet 19 is used to connect to the oil path in the oil and gas two-fluid nozzle; in actual use, the methyl ester fuel in the methyl ester fuel source enters the cup body 5 from the feed port 37 of the solenoid valve body 3, flows through the oil inlet 18 after being filtered, and then enters the oil and gas two-fluid nozzle from the oil outlet 19; the air pressurized by the air booster passes through the air inlet 12 and the air outlet 13 on the air pipe 11 in turn and then enters the oil and gas two-fluid nozzle.

[0042] The oil pipe 17 and the air pipe 11 are integrally formed with the cup body 5, which is not only simpler in production and processing technology, but also reduces the connection points between components, reduces the leakage points in the pipeline, reduces the probability of leakage, and ensures the airtightness of the combustion system; at the same time, it also makes installation more convenient and improves installation efficiency.

[0043] The filter screen 7 can filter out mechanical impurities in the methyl ester fuel, thereby preventing the mechanical impurities in the methyl ester fuel from clogging the pipelines in the combustion system, and effectively improving the stability of the combustion system.

[0044] The solenoid valve body 3 is used to open and close the oil inlet circuit. Since the discharge port 38 of the solenoid valve body 3 is located inside the cover body 2, in actual use, when the methyl ester fuel enters the cup body 5, the amount of oil inside the cup body 5 is more sufficient, thereby ensuring the supply of methyl ester fuel and making the oil supply more stable, thereby avoiding the situation of "spitting fire" or flameout due to insufficient oil supply. The "spitting fire" phenomenon refers to the situation of flame swallowing and puffing during use, thereby ensuring the stability of the combustion system during use.

[0045] It should be noted that the solenoid valve body 3 is a normally closed solenoid valve, which opens when powered on and closes to cut off the oil circuit when powered off.

[0046] Among them, the cup body 5 is connected to the cover body 2 by threads; in this embodiment, an external thread 27 is provided at the opening of the cover body 2, and an internal thread 28 is provided at the opening of the cup body 5, and the cup body 5 and the cover body 2 are connected by the internal thread 28 and the external thread 27.

[0047] In this way, the assembly of the cup body 5 and the cover body 2 is simpler in actual use, which can effectively improve the assembly efficiency.

[0048] For further optimization, the opening of the cup body 5 is provided with a stepped platform 29, the internal thread 28 is provided on the side of the stepped platform 29, a slot 30 is provided on the end face of the stepped platform 29, a sealing gasket 31 is provided in the slot 30, and after the cup body 5 and the cover body 2 are screwed together, the cover body 2 is tightly pressed against the sealing gasket 31.

[0049] In this way, the provided card slot 30 can prevent the sealing gasket 31 from moving during the rotation of the cover body 2; and the provided sealing gasket 31 can make the connection between the cup body 5 and the cover body 2 tighter, so that the cup body 5 and the cover body 2 form a sealing structure after they are screwed together.

[0050] Further optimization, the side wall of the cup body 5 is provided with a support ear 32, and the support ear 32 is provided with a mounting hole 33, and the mounting hole 33 is a strip hole. In this way, it is more convenient to install the cup body 5, and the strip hole can ensure that the position of the cup body 5 can be finely adjusted during the installation process.

[0051] In actual use, the mounting hole 33 may also be set as a round hole.

[0052] To be more specific, in this embodiment, the filter screen 7 includes a bracket 8 and a filter screen 9 disposed on the bracket 8 , a support protrusion 34 is disposed on the inner wall of the cup body 5 , and the bracket 8 of the filter screen 7 is placed on the support protrusion 34 .

[0053] A positioning groove is provided on one side of the bracket 8 that contacts the supporting protrusion 34 . When the bracket 8 is installed on the supporting protrusion 34 , the positioning groove can be engaged with the supporting protrusion 34 .

[0054] In this way, it is convenient to install the filter screen 7 in actual use, and the positioning groove can ensure that the filter screen 7 will not rotate after installation.

[0055] In actual use, the end of the adjusting rod Ⅰ10 is connected with a handle 35, so that it is more convenient to adjust the oil-gas mixture ratio.

[0056] Among them, it needs to be further explained that the linkage assembly 23 includes a driving wheel 24 and a driven wheel 25, the driving wheel 24 is a full-tooth gear, and the driven wheel 25 is provided with three-quarter meshing teeth 26 on the side of the wheel; the driving wheel 24 is installed on the adjusting rod Ⅰ10, and the driven wheel 25 is installed on the adjusting rod Ⅱ16, and the driving wheel 24 and the driven wheel 25 can mesh with each other.

[0057] In this way, since three-quarters of the meshing teeth 26 are provided on the side of the upper wheel of the driven wheel 25, the driving wheel 24 can be limited. In this way, in actual use, the driving wheel 24 and the driven wheel 25 can be prevented from being separated. The other quarter of the driven wheel 25 is not provided with meshing teeth 26, so that the driven wheel 25 can only rotate within 270°.

[0058] In actual use, at least one sealing ring 36 is provided between the adjusting rod Ⅰ10 and the adjusting port Ⅰ14; at least one sealing ring 36 is provided between the adjusting rod Ⅱ16 and the adjusting port Ⅱ1901; the provided sealing ring 36 can further prevent air leakage or oil leakage.

[0059] As a further optimization, a boss 20 with a polygonal structure is provided at the upper end of the cover body; thus, it is more convenient in the actual assembly process, and the boss 20 can be clamped with a wrench and then rotated.

[0060] Although the preferred embodiments of the present invention have been described, those skilled in the art may make additional changes and modifications to these embodiments once they are aware of the basic creative concepts. Therefore, the appended claims are intended to be interpreted as including the preferred embodiments and all changes and modifications that fall within the scope of the present invention. The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. It should be pointed out that any modifications, equivalent substitutions and improvements made within the spirit and principles of the present invention should be included in the scope of protection of the present invention.
