[0034] As Figure 1 and Figure 2 shown, the present embodiment provides a gas stove, which includes components such as a chassis 100, an air inlet pipe 200, a valve body 300, a gas guide pipe and a burner. The air inlet pipe 200 is respectively connected to the valve body 300 and the chassis 100 through a connection structure. The burner is installed in the chassis 100. The valve body 300 is connected to the burner through the gas guide pipe. Gas enters from one end of the air inlet pipe 200 and is controlled by the valve body 300 to flow into the burner. The flame starts to burn at the head of the burner to heat the cookware, realizing heating and cooking.

[0035] Combined with Figure 3As shown in the figure, the connection structure provided by this embodiment includes a connecting member 1. The connecting member 1 is provided with a clamping groove 11, a first connection hole 12, and a second connection hole 13. The clamping groove 11 is used to clamp the intake pipe 200 to realize the connection between the intake pipe 200 and the connecting member 1. The first connection hole 12 is used to connect the valve body 300 to realize the connection between the connecting member 1 and the valve body 300. The second connection hole 13 is used to connect the chassis 100 to realize the connection between the connecting member 1 and the chassis 100. The connecting member 1 can be, but is not limited to, a bracket structure.

[0036] During actual assembly, first insert the air inlet of the valve body 300 into the air outlet hole (not shown) of the intake pipe 200, then snap the intake pipe 200 into the clamping groove 11 on the connecting member 1, and then realize the connection between the connecting member 1 and the valve body 300 through the first connection hole 12, so as to realize the installation and fixation of the intake pipe 200 and the valve body 300. Finally, realize the connection between the connecting member 1 and the chassis 100 through the second connection hole 13, so as to realize the installation and fixation of the intake pipe 200, the valve body 300 and the chassis 100. This connection structure has no welding process, is simple in structure and reliable in connection, and realizes the rapid connection of the intake pipe 200, the valve body 300 and the chassis 100.

[0037] The connecting member 1 in this embodiment is in a shape of a capital "J", including a U-shaped installation part and two flanges respectively arranged on both sides of the installation part. The installation part is provided with a clamping groove 11 and a first connection hole 12, and the flanges are provided with second connection holes 13. The valve body 300 is provided with threaded holes, and the first connection hole 12 is a smooth hole. After the screw passes through the first connection hole 12, it is threadedly connected to the threaded hole on the valve body 300 to connect the connecting member 1 and the valve body 300. The second connection hole 13 is a threaded hole, and the chassis 100 is provided with a smooth hole. After the screw passes through the smooth hole on the chassis 100, it is threadedly connected to the second connection hole 13 to connect the connecting member 1 and the chassis 100. Specifically, the chassis 100 includes a bottom plate and side edges arranged on the peripheral sides of the bottom plate, and the connecting member 1 and the side edges are connected by screws.

[0038] The installation part includes a horizontal side and vertical sides respectively connected to both sides of the horizontal side. The horizontal side is provided with a communication groove 111 and a first connection hole 12. The communication groove 111 penetrates the horizontal side along the first direction, and the first direction is the extension direction of the intake pipe 200. Each of the two vertical sides of the installation part is provided with a limiting groove 112, and the communication groove 111 is connected to the two limiting grooves 112 on both sides to form the clamping groove 11. During assembly, the intake pipe 200 is first snapped into the communication groove 111 and then into the two limiting grooves 112 to realize the assembly of the intake pipe 200 and the connecting member 1.

[0039] To ensure the stable assembly of the intake pipe 200 and the connector 1, on the one hand, the bottom of the limit groove 112 is semicircular, and the diameter of the semicircle is not greater than the diameter of the intake pipe 200. The intake pipe 200 is finally clamped at the bottom of the limit groove 112. Therefore, designing the bottom of the limit groove 112 as a semicircle can better adapt to the shape of the intake pipe 200 to achieve stable clamping. And designing the diameter of the semicircle to be equal to or slightly smaller than the diameter of the intake pipe 200 can ensure the stability of the intake pipe 200 installed here, prevent the intake pipe 200 from shaking or falling off, and thus ensure the stability of the assembly of the intake pipe 200.

[0040] On the other hand, the width of the communication groove 111 is not greater than the diameter of the intake pipe 200. The width of the communication groove 111 is equal to or slightly smaller than the diameter of the intake pipe 200, making it difficult for the intake pipe 200 to fall off from the communication groove 111.

[0041] There are two first connection holes 12. The two first connection holes 12 are respectively located on both sides of the communication groove 111 along the second direction. The second direction is perpendicular to the first direction, and the second direction is the vertical direction. One first connection hole 12 is provided above and below the intake pipe 200 respectively, so as to realize the connection with the valve body 300 above and below the intake pipe 200 respectively, and the connection is reliable and firm.

[0042] At least one second connection hole 13 is provided on each of the two flanges. At least two connection points can improve the connection reliability between the connector 1 and the chassis 100, and thus improve the connection reliability among the intake pipe 200, the valve body 300 and the chassis 100.

[0043] In this embodiment, two second connection holes 13 are provided on each flange along the second direction. In this way, the connector 1 is fixedly connected to the side of the chassis 100 through the four second connection holes 13, improving the connection stability and reliability, and thus ensuring the connection reliability among the valve body 300, the intake pipe 200 and the chassis 100.

[0044] The connecting structure further includes a support member 2 for realizing the support and fixation of the chassis 100 and the intake pipe 200. The support member 2 is sleeved on the intake pipe 200 and can space the intake pipe 200 and the chassis 100 apart. A third connection hole (not shown) is provided on the support member 2 for connecting the chassis 100. The intake pipe 200 is an L-shaped elbow pipe as a whole, including a first pipe and a second pipe connected to each other. An intake end is provided on the first pipe, and a sealing end is provided on the second pipe. The intake end is used to connect a prefabricated joint and connect to a gas pipeline. The sealing end is located at the end of the intake pipe 200 for sealing the end of the pipeline. The prefabricated joint is a pre-processed connection joint for connecting a hose joint of a gas pipeline. The support member 2 is sleeved on the first pipe and is spaced from the intake pipe 200. The support member 2 can be a bracket, including a support portion and a fixing portion connected to each other. A through hole is provided on the support portion for sleeving the intake pipe 200, and a third connection hole is provided on the fixing portion. The third connection hole is a clearance hole. A threaded hole is provided on the bottom plate of the chassis 100. After a screw passes through the third connection hole, it is threadedly connected to the threaded hole on the bottom plate to realize the fixation of the support member 2 and the chassis 100, thereby realizing the support and fixation of the intake pipe 200.

[0045] The gas stove provided by this embodiment includes the above-mentioned connecting structure. The intake pipe 200 is connected to the valve body 300 and the chassis 100 respectively through this connecting structure. Since there is no need for a welding and sealing process, the manufacturing process is simple, the structure is reliable, the processing process is environmentally friendly, and the production efficiency is higher.
