Detailed Implementation

[0016] The following descriptions of the embodiments are made with reference to the accompanying drawings, illustrating specific embodiments in which the present invention can be implemented. The directional terms used in this invention, such as up, down, front, back, left, right, inside, outside, side, etc., are merely for the purpose of referring to the accompanying drawings. Therefore, the directional terms used are for the purpose of explaining and understanding the present invention, and not for limiting the present invention. In the drawings, structurally similar units are indicated by the same reference numerals.

[0017] The following description, in conjunction with the accompanying drawings, further clarifies the specific embodiments of the present invention, making the technical solution and its beneficial effects clearer and more explicit.

[0018] See appendix Figures 1 to 5The present invention includes a valve body 1, characterized in that: the valve body 1 includes an air inlet pipe 101, an air outlet pipe 102, an auxiliary pipe 103 and an auxiliary pipe 2 104, all integrally formed and whose central axes are located on the same plane; the air outlet pipe 102 is parallel to the auxiliary pipe 103; the end of the auxiliary pipe 2 104 facing inward is connected to the auxiliary pipe 103; the left end of the air outlet pipe 102 is connected to the middle of the auxiliary pipe 2 104; one end of the air inlet pipe 101 is provided with an air inlet 1010, and the other end is connected to the middle of the auxiliary pipe 103.

[0019] The intake pipe 101 is integrally formed with the valve body 1, reducing the number of connection points, simplifying the structure, and reducing the risk of air leakage. At the same time, the integral formation of the intake pipe 101 and the valve body 1 reduces the bends in the gas entering the auxiliary pipe 103, making the gas supply smoother.

[0020] The central axes of the air inlet pipe 101, air outlet pipe 102, auxiliary pipe one 103 and auxiliary pipe two 104 are all located on the same plane, which makes the structure of the valve body 1 more flat and easier to install.

[0021] Furthermore, a valve core 2 is provided inside the left end of the auxiliary tube 103. The valve core 2 is provided with a tapered part 201. The tapered part 201 is provided with a vent hole 202. The vent hole 202 is a rounded quadrilateral. The long side of the vent hole 202 faces the same direction as the tapered surface of the tapered part 201.

[0022] The rounded quadrilateral vent 202 can increase the gas flow, thereby providing a larger gas flow to the stove and making the stove fire more intensely. At the same time, the rounded quadrilateral vent 202 can make the sealing gap between the conical part 201 and the auxiliary pipe 103 tighter, thereby improving its airtightness.

[0023] Furthermore, an ignition seat 105 corresponding to the valve core 2 is provided above the auxiliary tube 103. An ignition inclined surface 106 facing the upper right is provided at the upper end of the ignition seat 105. The angle between the ignition inclined surface 106 and the auxiliary tube 103 is greater than 0 degrees and less than 90 degrees. An ignition tube 3 is connected to the auxiliary tube 103 on the ignition inclined surface 106.

[0024] Furthermore, a fixing seat 107 is provided above the right end of the auxiliary tube 103, and a grounding hole 108 is provided on the top surface of the fixing seat 107.

[0025] A fixing seat 107 and a grounding hole 108 are provided at the end of the auxiliary tube 103, which makes it easier to install the grounding wire and makes the wiring more sensitive.

[0026] Furthermore, a number of reinforcing ribs 109 are provided at the connection between the air intake pipe 101 and the auxiliary pipe 103, and the reinforcing ribs 109 are used to strengthen the structural strength of the connection.
