At this time, the installation reference of the plug-in valve and the installation reference of the ejector tube are different. Due to the differences in assembly and the tolerance fluctuations of the component sizes, the coaxiality fluctuation range of the nozzle and the ejector tube is large, which in turn affects the ejection effect and cannot meet the burner with high ejection requirements. The flue gas performance and the stability of burner combustion are affected. Utility Model Content

[0003] The technical problem to be solved by the utility model is to overcome the defects of the prior art and provide a direct-insert valve component and a gas stove.

[0004] The utility model solves the above technical problems through the following technical solutions:

The connection method between the positioning arm and the positioning surface can be bolt connection, buckle connection, pin connection, etc. The connecting piece can be a rigid material such as a bolt or a rivet, or a soft material such as a tape. Considering the stability of the connection between the positioning arm and the positioning surface, a rigid material such as a bolt is preferably used as the connecting piece.

[0009] Furthermore, the ejector tube includes an outer ring ejector tube and an inner ring ejector tube, the outer ring ejector tube and the inner ring ejector tube are arranged side by side, and the nozzle includes an outer ring nozzle and an inner ring nozzle, the outer ring nozzle and the outer ring ejector tube are plugged in, and the inner ring nozzle and the inner ring ejector tube are plugged in.

[0010] In this solution, the above structural form is adopted to enable the utility model to be applicable to a two-ring burner. In other embodiments, the utility model can also be used for a single-ring burner, a three-ring burner or a burner with more ring levels, and the structure thereof can refer to this embodiment, and will not be described in detail to avoid repetition.

In the existing plug-in valve structure, the solenoid valve is widely used, and this solution takes into account the position of the solenoid valve and adjusts the positions of the two positioning arms accordingly.

[0013] Furthermore, a fixed leg is provided between the outer ring air intake pipe and the inner ring air intake pipe, one end of the fixed leg is provided corresponding to the connection between the outer ring positioning arm and the outer ring air intake pipe, and the other end of the fixed leg is provided corresponding to the connection between the inner ring positioning arm and the inner ring air intake pipe.

[0014] In this scheme, the above-mentioned structural form is adopted, and a fixed foot is set between the outer ring air intake pipe and the inner ring air intake pipe to ensure the stability between the outer ring air intake pipe and the inner ring air intake pipe.

[0017] Furthermore, the connecting member is a bolt, and the inner wall of the first positioning hole is provided with a thread matching the bolt, or the inner wall of the second positioning hole is provided with a thread matching the bolt.

[0022] The plug-in valve is connected to the gas inlet pipe, and the inlet pipe is fixed to the chassis through a mounting seat. The positioning of the nozzle on the plug-in valve is often affected by the installation position of the mounting seat.

Therefore, there are different installation references for the nozzle and the ejector tube. In addition, due to the tolerance fluctuations in the design dimensions of the components, there are fluctuations in the coaxiality of the nozzle and the ejector tube. In this scheme, the above-mentioned structural form is adopted.

[0056] A preferred embodiment is given below, and the present invention is described more clearly and completely in conjunction with the accompanying drawings.

[0057] The utility model provides a plug-in valve assembly, which comprises a plug-in valve 1 and an ejector tube 21, wherein the plug-in valve 1 comprises a nozzle 11, the ejector tube 21 comprises an ejector tube center hole 213, the nozzle 11 and the ejector tube center hole 213 are plugged together, and is characterized in that the plug-in valve assembly further comprises a connecting piece and a positioning arm 13, the nozzle 11 and the positioning arm 13 are connected, the ejector tube 21 comprises a positioning surface 22, and the connecting piece connects the positioning arm 13 and the positioning surface 22.

[0058] like Figure 2 and Figure 3 As shown, the positioning arm 13 cooperates with the positioning surface 22 to form a fixed structure for positioning the nozzle 11 and the ejector tube 21, so that the ejector tube 21 and the nozzle 11 can be connected to each other before being installed on the chassis 3 of the gas stove to form a strong fixed relationship. When the positioning arm 13 and the positioning surface 22 are fixedly connected by a connecting piece, the ejector tube 21 and the nozzle 11 can be arranged relatively coaxially to ensure the ejection effect of the gas ejected from the nozzle 11. The nozzle 11 and the ejector tube 21 are directly assembled to achieve a unified reference for the installation of the nozzle 11 and the ejector tube 21, ensure the coaxiality accuracy of the two, improve the ejection effect and the flame combustion stability of the burner 2, avoid the coaxiality deviation caused by fixing the ejector tube 21 and the nozzle 11 on the chassis 3 separately and then plugging the two into the holes in the prior art, and avoid the influence caused by the tolerance fluctuation of the component size design and the different installation references during assembly. The connection method between the positioning arm 13 and the positioning surface 22 can be a bolt connection, a snap connection, a pin connection, etc. The connecting parts can be rigid materials such as bolts and rivets, or soft materials such as tapes. Considering the stability of the connection between the positioning arm 13 and the positioning surface 22, rigid materials such as bolts are preferably used as connecting parts to ensure the firmness of the connection between the ejector tube 21 and the nozzle 11 before being installed on the chassis 3.

[0059] like Figure 1 As shown, the plug-in valve 1 includes an air intake pipe 12, a positioning arm 13 is directly arranged on the outer periphery of the air intake pipe 12, the air intake pipe 12 and the positioning arm 13 are integrally formed, and the nozzle 11 is detachably connected to the end of the air intake pipe 12; in addition, in this embodiment, along the connection direction A of the nozzle 11 relative to the ejection tube 21, the positioning arm 13 abuts against the positioning surface 22.

[0060] The positioning arm 13 is arranged at the outer periphery of the air intake pipe 12, so that the connection coaxiality between the nozzle 11 and the ejector tube 21 is higher, the structure is more compact and convenient to manufacture; the air intake pipe 12 and the positioning arm 13 are integrally formed to achieve fixed connection, which is also more convenient to manufacture and process. The positioning arm 13 is abutted against the positioning surface 22 along the insertion direction of the nozzle 11 relative to the ejector tube 21 to ensure that the nozzle 11 will no longer move along the depth direction of the ejector tube center hole 213 after the nozzle 11 and the ejector tube center hole 213 are inserted.

[0061] like Figure 1 As shown, the ejector tube 21 includes an outer ring ejector tube 211 and an inner ring ejector tube 212, and the outer ring ejector tube 211 and the inner ring ejector tube 212 are arranged side by side. The nozzle 11 includes an outer ring nozzle 111 and an inner ring nozzle 112, and the outer ring nozzle 111 and the outer ring ejector tube are plugged in, and the inner ring nozzle 112 and the inner ring ejector tube are plugged in. Through the above-mentioned structural arrangement, the utility model can be applied to a two-ring burner. Of course, in other embodiments, the improvements of the nozzle and the ejector tube in this scheme can also be used in a single-ring burner, a three-ring burner or a burner with more ring levels. The specific structural arrangement scheme can refer to this embodiment, and in order to avoid repetition, it will not be described in detail.

[0062] In this embodiment, the plug-in valve 1 includes a solenoid valve 15, which is arranged on one side of the plug-in valve 1, the positioning arm 13 includes an outer ring positioning arm 131 and an inner ring positioning arm 132, the intake pipe 12 includes an outer ring intake pipe 121 and an inner ring intake pipe 122, the outer ring positioning arm 131 is arranged on the side of the outer ring intake pipe 121 away from the inner ring intake pipe 122, the inner ring positioning arm 132 is arranged on the side of the inner ring intake pipe 122 away from the outer ring intake pipe 12, and the position of the solenoid valve 15 and the position of the positioning arm 13 are spaced apart.

[0063] The plug-in valve 1 includes a solenoid valve 15, an outer ring positioning arm 131 is arranged on the side of the outer ring air intake pipe 121 away from the inner ring air intake pipe 122, and the inner ring positioning arm 132 is arranged on the side of the inner ring air intake pipe 122 away from the outer ring air intake pipe 12, and at the same time, the position of the solenoid valve 15 and the positions of the two positioning arms are spaced apart to ensure convenient loading and unloading, and the solenoid valve 15 and the positioning arm 13 will not be re-positioned during assembly. The specific structure and function of the solenoid valve 15 in the plug-in valve 1 structure are not described here because they belong to the scope of the prior art. This solution takes into account the position of the solenoid valve 15 and adjusts the positions of the two positioning arms accordingly, effectively avoiding the existence of the positioning arms affecting the normal installation and use of other components.

[0064] A fixed leg 14 is provided between the outer ring air intake pipe 121 and the inner ring air intake pipe 122 , one end of the fixed leg 14 is provided corresponding to the connection between the outer ring positioning arm 131 and the outer ring air intake pipe 121 , and the other end of the fixed leg 14 is provided corresponding to the connection between the inner ring positioning arm 132 and the inner ring air intake pipe 122 .

[0065] A fixing foot 14 is arranged between the outer ring air intake pipe 121 and the inner ring air intake pipe 122 to ensure the stability between the outer ring air intake pipe 121 and the inner ring air intake pipe 122. The present scheme makes targeted improvements to the structure where the fixing foot 14 is installed between the air intake pipe 12 and the chassis 3 to avoid the ejector pipe 21 and the nozzle 11 connected to the air intake pipe 12 being separately fixed on the chassis 3 so that the two have different installation references.

[0066] The positioning arm 13 defines a first positioning hole 133 , and the positioning surface 22 defines a second positioning hole 221 corresponding to the first positioning hole 133 . The connecting member passes through the first positioning hole 133 and the second positioning hole 221 in sequence to connect the positioning arm 13 and the positioning surface 22 .

[0067] A first positioning hole 133 is provided on the positioning arm 13 and a corresponding second positioning hole 221 is provided on the positioning surface 22. The positioning arm 13 and the positioning surface 22 are connected by a connecting member through a punching connection. The connecting member may be a bolt, a pin or a rivet. The punching connection method provides a higher connection strength than other connection methods, such as a snap connection, and is more conducive to improving the coaxiality and stability of the nozzle 11 and the ejector tube 21.

[0068] The connecting member is a bolt, and the inner wall of the first positioning hole 133 is provided with a thread matching the bolt, or the inner wall of the second positioning hole 221 is provided with a thread matching the bolt.

[0069] By providing threads on the inner walls of the first positioning hole 133 and the second positioning hole 221 and using bolts as connecting members to connect the positioning arm 13 and the positioning surface 22, installation and disassembly are convenient and simple, and the bolts have strong bearing pressure.

[0070] At the same time, the positioning surface 22 and the ejector tube 21 are integrally formed, which is more convenient for processing and manufacturing. In the traditional manufacturing process of the ejector tube, the ejector tube is often integrally sand-cast or die-casted with a burner head on the burner using cast iron material. The positioning surface 22 and the ejector tube 21 are integrally formed to achieve fixed connection, which is more convenient for manufacturing and processing.

[0071] like Figure 4 As shown, the utility model also provides a gas stove, which is provided with the above-mentioned plug-in valve assembly. In order to facilitate the display of the specific position and structure of the plug-in valve assembly provided inside the gas stove, Figure 4 In this embodiment, the plug-in valve assembly further includes a gas inlet pipe 16, the inlet end of the plug-in valve 1 is connected to the gas inlet pipe 16, a mounting seat 17 is provided at the lower side of the gas inlet pipe 16, wherein a long waist hole 171 is provided on the mounting seat 17, and the gas inlet pipe 16 is fixed to the chassis 3 of the gas stove through the long waist hole 171 of the mounting seat 17.

[0072] In the prior art, the plug-in valve 1 is connected to the gas intake pipe 16, and the intake pipe 12 is fixed to the chassis 3 through the mounting seat 17. The positioning of the nozzle 11 on the plug-in valve 1 is often affected by the installation position of the mounting seat 17. The ejector pipe 21 is arranged on the burner 2, and the installation of the burner 2 is realized through the base of the burner 2. Therefore, there are different installation references for the nozzle 11 and the ejector pipe 21. In addition, due to the fluctuation of the tolerance of the design dimensions of the components, the coaxiality of the nozzle 11 and the ejector pipe 21 fluctuates. In the solution provided in this embodiment, a positioning arm 13 is provided to achieve a rigid connection with the ejector tube. The coaxiality of the nozzle 11 and the ejector tube 21 is first determined by the positioning arm 13 and the positioning surface 22, and then the gas intake pipe 16 is fixed to the chassis 3 through the mounting seat 17. A long waist hole 171 is provided on the mounting seat 17, which provides a certain installation margin, so that when the mounting seat 17 is connected to the chassis 3 by connecting parts including bolts or other fasteners, the dimensional deviation caused by the part accuracy can be released at the long waist hole of the mounting seat 17.
