[0002] A gas stove refers to a kitchen appliance that uses natural gas, liquefied gas, coal gas or other gas fuel as a medium for open flame heating. When the gas stove is working, the gas fuel enters the stove from the air inlet pipe, flows through the nozzle after passing through the gas valve body, and the outside air flows in from the nozzle and mixes with the gas fuel before flowing to the burner head, and is ignited by the ignition device to form a flame, which is used to heat the cooker placed on the pot support.

[0003] It should be noted that the flow diameter and length of the nozzle of the existing gas stove are different according to the gas fuel. It is often the case that users use natural gas at home, but mistakenly buy a gas stove for liquefied gas, resulting in obvious differences in the color and shape of the flame after ignition. At this time, it is necessary to replace the gas stove or ask the master to replace the nozzle of the gas stove.

[0029] Schematic gas stove nozzle,

[0030] refer to Figures 1 to 3 According to a preferred embodiment of the utility model, a nozzle for a gas stove is provided, wherein both ends of the nozzle for the gas stove are respectively connected to the gas valve body and the burner head, and the nozzle for the gas stove comprises an air inlet interface 10, an air outlet interface 20, an intermediate piece 30 and a reducing piece 40.

[0031] Specifically, Figure 2As shown, one end of the air inlet interface 10 is connected to the gas valve body, one end of the air outlet interface 20 is connected to the burner head, the middle piece 30 includes an external air inlet portion 301, a first connection portion 302 and a second connection portion 303, the two ends of the external air inlet portion 301 are threadedly connected to the first connection portion 302 and the second connection portion 303 respectively, the external air inlet portion 301 has a plurality of large air holes 3011 arranged in a ring shape, the length of the first connection portion 302 is less than the length of the second connection portion 303, and the end of the first connection portion 302 or the second connection portion 303 facing away from the external air inlet portion 301 is threadedly connected to the air inlet interface 10, the end of the second connection portion 303 or the first connection portion 302 facing away from the external air inlet portion 301 is threadedly connected to the air outlet interface 20, and the reducing member 40 is detachably installed at the end of the air inlet interface 10 facing away from the middle piece 30.

[0032] Furthermore, if Figure 2 As shown, the air inlet interface 10 has a first channel 101, which is composed of a tapered hole 1011, a tightening hole 1012 and an expansion hole 1013, and the tightening hole 1012 is located between the tapered hole 1011 and the expansion hole 1013. The air outlet interface 20 has a through second channel 201, and the second channel 201 is a circular cavity.

[0033] In addition, if Figure 3 As shown, the reducing member 40 is detachably arranged in the first channel 101, and the reducing member 40 has a tightening channel 401. When the reducing member 40 is arranged in the first channel 101, the tightening channel 401 is connected with the expansion hole 1013, and the aperture of the tightening channel 401 close to the expansion hole 1013 is 0.8-1 mm, and the aperture of the tightening hole 1012 is 1.3-1.5 mm.

[0034] It should be noted that the length of the external air inlet 301 of the natural gas nozzle is shorter than that of the external air inlet 301 of the liquefied gas nozzle, and the diameter of the tightening hole 1012 of the natural gas nozzle is mostly 1.3-1.5 mm, while the diameter of the tightening hole 1012 of the liquefied gas nozzle is mostly 0.8-1 mm. In view of this, in the embodiment of the present application, in order to achieve the unit time flow rate of the gas fuel flowing into the expansion hole 1013 to adapt to the corresponding gas needs, the reducing member 40 is provided. More specifically, referring to Figure 3When the reducing member 40 is installed in the first channel 101, the tightening hole 1012 is replaced by the tightening channel 401 on the reducing member 40. At this time, the gas fuel flows into the expansion hole 1013 through the tightening channel 401 and flows to the intermediate member 30. Since the aperture of the tightening channel 401 close to the expansion hole 1013 is 0.8-1 mm, the gas stove nozzle is suitable for liquefied gas at this time; conversely, when the gas fuel is natural gas, only the reducing member 40 needs to be removed, and the gas fuel flows into the expansion hole 1013 through the tightening hole 1012. Since the aperture of the tightening hole 1012 is 1.3-1.5 mm, the gas stove nozzle is suitable for natural gas at this time. In addition, by providing the intermediate piece 30, when the first connecting portion 302 is connected to the air inlet interface 10 and the second connecting portion 303 is connected to the air outlet interface 20, the overall length of the gas stove nozzle is shorter, which is suitable for application scenarios in which the gas fuel is natural gas; when the first connecting portion 302 is connected to the air outlet interface 20 and the second connecting portion 303 is connected to the air inlet interface 10, the overall length of the gas stove nozzle is longer, which is suitable for application scenarios in which the gas fuel is liquefied gas. It is obvious that compared with the prior art, the embodiment of the present application has the advantage of being switchable between natural gas and liquefied gas.

[0035] Furthermore, if Figure 1 As shown, a cross section of the external air inlet portion 301 is a regular hexagon, so that an assembler can easily rotate the external air inlet portion 301 with a wrench.

[0036] Furthermore, in order to realize the threaded connection between the first connection part 302 or the second connection part 303 and the air inlet interface 10 or the air outlet interface 20, as shown in FIG. Figure 2 and Figure 3 As shown, the first connection portion 302 and the second connection portion 303 are both cylindrical protrusions, and the first connection portion 302 and the second connection portion 303 both have a through threaded hole 3021 .

[0037] Furthermore, in order to realize the conduction of the gas in the intermediate piece 30, as Figure 2 As shown, the external air intake portion 301 also has a first expanded hole 3012 and a second expanded hole 3013. The first expanded hole 3012 is connected to the threaded hole 3021 on the first connecting portion 302, and the second expanded hole 3013 is connected to the threaded hole 3021 on the second connecting portion 303. Both sides of each large hole 3011 are respectively connected to the first expanded hole 3012 and the second expanded hole 3013.

[0038] Furthermore, if Figure 3As shown, the reducing member 40 includes a conical portion 402 and a straight cylindrical portion 403. When the straight cylindrical portion 403 is inserted into the tightening hole 1012, the conical portion 402 fits against the hole wall of the conical hole 1011. The material of the reducing member 40 is preferably polyphenylene sulfide plastic, so that the straight cylindrical portion 403 can be inserted into the tightening hole 1012; in addition, the tightening channel 401 is designed to imitate the conical portion 402 and the straight cylindrical portion 403; in addition, in order to facilitate the removal of the reducing member 40, the tightening channel 401 is located on one side of the conical portion 402 and has a plurality of buckle grooves (not marked in the figure).

[0039] Furthermore, in order to facilitate the threaded connection between the two ends of the gas inlet interface 10 and the gas valve body and the intermediate piece 30, as shown in FIG. Figure 2 As shown, the two ends of the air inlet interface 10 respectively have a first threaded portion 102 and a second threaded portion 103, the first threaded portion 102 is connected to the gas valve body, the second threaded portion 103 is connected to the first connection portion 302 or the threaded hole 3021 on the second connection portion 303, and the length of the second threaded portion 103 is less than the length of the first threaded portion 102.

[0040] Furthermore, in order to facilitate the air inlet port 10 to be screwed into the second connection portion 303 to a predetermined depth and not be screwed in further, as shown in FIG. Figure 2 and Figure 3 As shown, a thread back groove 104 is provided between the first threaded portion 102 and the second threaded portion 103 , and the distance from one end surface of the second threaded portion 103 away from the thread back groove 104 to the groove surface of the thread back groove 104 is equal to the hole depth of the threaded hole 3021 on the first connecting portion 302 .

[0041] It should be noted that when the disassembler screws the second threaded portion 103 into the threaded hole 3021 on the second connecting portion 303, and the end face of the threaded backing groove 104 close to the second threaded portion 103 is flush with the hole edge of the threaded hole 3021, the air inlet interface 10 is screwed into place. At this time, the disassembler does not need to further screw in the air inlet interface 10.

[0042] In addition, if Figure 2 and Figure 3 As shown, the length of the air outlet interface 20 is greater than the length of the air inlet interface 10 .

[0043] In summary, the nozzle for a gas stove based on the embodiment of the present application is explained, which provides the nozzle for a gas stove with advantages such as switchable use of natural gas or liquefied gas.
