[0040] Please refer to the following Figure 1-Figure 4The stove 100 and valve seat 130 according to the embodiment of the present application are described. It should be noted that the stove 100 may refer to a stove 100 that is heated by direct fire with gas fuels such as liquefied petroleum gas, artificial coal gas, and natural gas. The stove 100 is easy to use and is deeply loved by people, especially Chinese food that likes to be stir-fried with high heat. It has a wide range of uses. Among them, there is a type of stove 100 with multiple burners and gas is supplied through a gas pipe. A steel gas pipe welding flange is usually used as a valve seat 130 to install a valve body 120 of multiple burners. The flange of the valve body 120 and the flange of the valve seat 130 are fixed by surface contact.

[0041] like Figure 3 and Figure 4 As shown, the cooker 100 according to the embodiment of the present application includes a housing 110 , a valve body 120 and a valve seat 130 .

[0042] like Figure 4 As shown, the housing 110 defines an installation chamber, and the burner, valve body 120, pipeline and other components are arranged in the installation chamber of the housing 110. The housing 110 is provided with a plug hole 111. For example, the bottom wall of the housing 110 can be provided with the plug hole 111.

[0043] See also Figure 1 and Figure 2 As shown, the valve seat 130 is fixedly connected to the valve body 120, a gas distribution pipe 132 is provided in the valve seat 130, the gas distribution pipe 132 is communicated with the valve body 120, a first mounting portion 133 and a second mounting portion 135 are provided on the valve seat 130, the first mounting portion 133 and the second mounting portion 135 are spaced apart along the circumferential direction of the gas distribution pipe 132, the first mounting portion 133 is fitted with the inner surface of the shell 110, the second mounting portion 135 is penetrated through the insertion hole 111 and is fitted with the outer surface of the shell 110, and the first mounting portion 133 is fixedly connected to the shell 110.

[0044] It should be noted that when the valve seat 130 is subjected to a pulling force, since the shell 110 is fixedly connected to the first mounting portion 133, the connection relationship between the shell 110 and the first mounting portion 133 can play a blocking role on the first mounting portion 133, and the blocking force surrounds the outer circumference of the gas distribution pipe 132 in a first direction; and since the first mounting portion 133 is located on the inner surface of the shell 110, and the second mounting portion 135 is located on the outer surface of the shell 110, the first mounting portion 133 and the second mounting portion 135 are distributed along the circumferential direction of the gas distribution pipe 132, so that when the first mounting portion 133 is subjected to a force in the first direction, the second mounting portion 135 inserted in the socket 111 is subjected to resistance in the second direction applied by the shell 110, and the second direction surrounds the outer circumference of the gas distribution pipe 132, and the second direction is opposite to the first direction. That is to say, when the valve seat 130 is subjected to a pulling force, the resistance exerted on the first mounting portion 133 is in the opposite direction to the resistance exerted on the second mounting portion 135. The resistance exerted on the first mounting portion 133 can prevent the valve seat 130 from tilting forward, and the resistance exerted on the second mounting portion 135 can prevent the valve seat 130 from tilting backward, thereby effectively preventing the valve seat 130 from twisting or tipping over.

[0045] According to the cooker 100 of the embodiment of the present application, a first mounting portion 133 and a second mounting portion 135 are provided on the valve seat 130, and the first mounting portion 133 and the second mounting portion 135 are spaced apart along the circumferential direction of the gas distribution pipe 132, the first mounting portion 133 is in contact with the inner surface of the shell 110, and the second mounting portion 135 is inserted into the insertion hole 111 and is in contact with the outer surface of the shell 110. When the valve seat 130 is subjected to a pulling force, the resistance exerted on the first mounting portion 133 is opposite to the resistance exerted on the second mounting portion 135. The resistance exerted on the first mounting portion 133 can prevent the valve seat 130 from tilting forward, and the resistance exerted on the second mounting portion 135 can prevent the valve seat 130 from tilting backward, thereby effectively preventing the valve seat 130 from twisting or tipping over.

[0046] According to some embodiments of the present application, see Figure 4 As shown, the second mounting portion 135 includes an inserting portion 136 and a clamping portion 137 connected to the inserting portion 136. The inserting portion 136 is connected to the valve seat 130, the inserting portion 136 is inserted into the insertion hole 111, the clamping portion 137 is fitted with the outer surface of the housing 110, and a step is constructed between the inserting portion 136 and the clamping portion 137. It should be noted that when the second mounting portion 135 is inserted into the insertion hole 111, the inserting portion 136 is inserted into the insertion hole 111, the clamping portion 137 is fitted with the outer surface of the housing 110, and the step structure constructed between the inserting portion 136 and the clamping portion 137 can form a hook structure and hook the housing 110. In this way, the second mounting portion 135 can clamp the housing 110, prevent the valve seat 130 from tipping over or tilting, and effectively slow down the torsion and tilting of the valve seat 130.

[0047] According to some embodiments of the present application, see Figure 1 and Figure 2 As shown, there may be a plurality of second mounting portions 135, and the plurality of second mounting portions 135 are spaced apart along the axial direction of the gas distribution pipe 132. In this way, a plurality of undercut fulcrums can be provided in the length direction of the valve seat 130, so that the valve seat 130 can be stably fixed in the housing 110, effectively preventing the valve seat 130 from tilting or falling. It should be noted that in order to improve the installation stability of the valve seat 130, according to some embodiments of the present application, see Figure 2 As shown, there may be a plurality of first mounting portions 133 , and the plurality of first mounting portions 133 are spaced apart and distributed along the axial direction of the gas distribution pipe 132 .

[0048] In some embodiments, the second mounting portion 135 and the socket 111 can be interference fit. This can improve the stability of the fit between the undercut structure and the housing 110. Interference fit is a common mechanical connection method used to ensure a firm and stable connection between two parts. The so-called interference fit means that the inner diameter of the socket 111 is slightly smaller than the outer diameter of the second mounting portion 135, so that a certain amount of pressure needs to be applied to the second mounting portion 135 during assembly before it can be inserted into the socket 111. This connection method can effectively avoid relative displacement or loosening of parts during use, thereby ensuring the reliability and stability of the mechanical structure.

[0049] According to some embodiments of the present application, see Figure 1 and Figure 2 As shown, a connecting portion 138 is provided on the valve seat 130, and the first mounting portion 133 and the second mounting portion 135 are both fixedly connected to the connecting portion 138. This facilitates the arrangement of the first mounting portion 133 and the second mounting portion 135. In addition, in order to improve the structural strength of the connecting portion 138, a plurality of reinforcing ribs may be provided on the outer surface of the connecting portion 138.

[0050] In order to facilitate the arrangement of the first mounting portion 133 and the second mounting portion 135 and optimize the structure of the valve seat 130, according to some embodiments of the present application, such as Figure 1 and Figure 2 As shown, on the same connection portion 138, the first mounting portion 133 and the second mounting portion 135 are spaced apart in the axial direction of the gas distribution pipe 132. Of course, the arrangement of the first mounting portion 133 and the second mounting portion 135 is not limited thereto. For example, in other embodiments, on the same connection portion 138, the first mounting portion 133 and the second mounting portion 135 are spaced apart in the circumferential direction of the gas distribution pipe 132.

[0051] According to some embodiments of the present application, see Figure 1 and Figure 2As shown, the first mounting portion 133 and the housing 110 can be connected by screws. It should be noted that the use of screws to mount the first mounting portion 133 and the housing 110 together not only has the advantage of simple assembly, but also can improve the assembly stability between the first mounting portion 133 and the housing 110. In order to facilitate the installation of the first mounting portion 133 on the housing 110, in some examples of the present application, a plurality of spaced screw holes 134 are provided on the first mounting portion 133. It should be noted that the number of screw holes 134 located on the same first mounting portion 133 is not limited here. For example, on the same first mounting portion 133, one screw hole 134 can be provided, or a plurality of screw holes 134 can be provided. When a plurality of screw holes 134 are provided on the same first mounting portion 133, the plurality of screw holes 134 can be spaced apart along the axial direction of the gas distribution pipe 132, or can be spaced apart along the circumferential direction of the gas distribution pipe 132.

[0052] According to some embodiments of the present application, see Figure 1 and Figure 2 As shown, the extension direction of the first mounting portion 133 is perpendicular to the axial direction of the valve seat 130. This makes it easy to mount the first mounting portion 133 on the housing 110. In some examples of the present application, the valve seat 130 is in an elongated strip shape and is an integrally formed part. On the one hand, the structural strength of the valve seat 130 can be improved; on the other hand, the manufacturing process of the valve seat 130 can be simplified and the production cost can be reduced. For example, in some examples, the valve seat 130 can be a casting.

[0053] Refer to the following Figure 1-Figure 4 The valve seat 130 according to the embodiment of the present application is described in detail with a specific example. It is worth noting that the following description is only an exemplary description, and is not a specific limitation to the present application.

[0054] See also Figure 1 and Figure 2 As shown, the valve seat 130 includes a body portion 131, a first mounting portion 133, and a second mounting portion 135. The body portion 131 is in an elongated strip shape, and a gas distribution pipe 132 is provided in the body portion 131, and the gas distribution pipe 132 can be connected to the valve body 120. For example, gas can enter the valve body 120 through the gas distribution pipe 132. The first mounting portion 133 and the second mounting portion 135 are spaced apart along the circumferential direction of the gas distribution pipe 132, the first mounting portion 133 is suitable for fitting with the inner surface of the housing 110, the second mounting portion 135 is penetrated and fitted with the outer surface of the housing 110, and at least one of the first mounting portion 133 and the second mounting portion 135 is fixedly connected to the housing 110.

[0055] See also Figure 2As shown, the valve seat 130 is an integrally formed casting and includes two connecting portions 138. The two connecting portions 138 are spaced apart in the axial direction of the gas distribution pipe 132. A first mounting portion 133 and a second mounting portion 135 are provided on each connecting portion 138. On one of the connecting portions 138, the first mounting portion 133 and the second mounting portion 135 are distributed along the circumferential direction of the gas distribution pipe 132; on the other connecting portion 138, the first mounting portion 133 and the second mounting portion 135 are staggered along the axial direction of the gas distribution pipe 132.

[0056] Each first mounting portion 133 is provided with two mounting holes, and each first mounting portion 133 is connected to the housing 110 by two screws, and the two screws and the two mounting holes are matched one by one. On one of the first mounting portions 133, the two screw holes 134 are spaced apart along the circumferential direction of the gas distribution pipe 132; on the other first mounting portion 133, the two screw holes 134 are spaced apart along the axial direction of the gas distribution pipe 132.

[0057] See also Figure 2 As shown, the second mounting portion 135 includes an inserting portion 136 and a clamping portion 137 connected to the inserting portion 136. The inserting portion 136 is connected to the valve seat 130, the inserting portion 136 is inserted into the insertion hole 111, the clamping portion 137 is in contact with the outer surface of the housing 110, and a step is constructed between the inserting portion 136 and the clamping portion 137. It should be noted that a step structure is constructed between the inserting portion 136 and the clamping portion 137. When it is inserted into the insertion hole 111, the inserting portion 136 is inserted into the insertion hole 111, the clamping portion 137 is in contact with the outer surface of the housing 110, and the step structure can form an inverted hook structure and hook the housing 110. In this way, the second mounting portion 135 can clamp the housing 110, prevent the valve seat 130 from tipping over or tilting, and effectively slow down the torsion and tilting of the valve seat 130.

[0058] It should be noted that, by providing the first mounting portion 133 and the second mounting portion 135 on the valve seat 130, the first mounting portion 133 and the second mounting portion 135 are spaced apart along the circumferential direction of the distribution pipe 132, the first mounting portion 133 is in contact with the inner surface of the shell 110, and the second mounting portion 135 is inserted into the insertion hole 111 and is in contact with the outer surface of the shell 110. When the valve seat 130 is subjected to a pulling force, the resistance exerted on the first mounting portion 133 is opposite to the resistance exerted on the second mounting portion 135. The resistance exerted on the first mounting portion 133 can prevent the valve seat 130 from tilting forward, and the resistance exerted on the second mounting portion 135 can prevent the valve seat 130 from tilting backward, thereby effectively preventing the valve seat 130 from twisting or tipping over.
