Description

Technical Field

[0001] This utility model relates to an ignition assembly installation structure for a gas valve. Background Technology

[0002] The gas valve is a core safety and control component in a gas stove, responsible for controlling the flow and control of gas. The reliability and stability of its ignition function directly affect the user experience and safety of the stove. Current technology has some inherent flaws in the connection method between the ignition needle holder and the valve body. A common structure involves fixing the holder to a side of the valve body or the pipe with a simple single screw. This connection method has a small contact area and few fixing points, making the holder prone to loosening or shifting during long-term use or vibration. Once the ignition needle deviates from its position, it can lead to ignition failure, delayed ignition, or partial ignition, affecting user experience. Utility Model Content

[0003] The purpose of this invention is to overcome the above-mentioned problems. We provide an ignition assembly mounting structure for a gas valve. Using this mounting structure to fix the frame can improve the stability of the frame after installation.

[0004] To achieve the above objectives, this utility model provides an ignition assembly installation structure for a gas valve, comprising a valve body, a frame, and an ignition needle. A first tube is provided on the front side of the valve body, and a second tube is provided on the top of the valve body above the first tube. A valve core cavity is provided inside the valve body, connecting the first tube and the second tube. The ignition needle is fixed to the frame, and a gas passage is provided on the frame. The ignition end of the ignition needle corresponds to the gas outlet end of the gas passage. The frame is provided with a mounting part that connects to the second tube. The mounting part has at least three side walls that fit against the outer wall of the second tube. The mounting part is fixed to the second tube by screws. The front end of the second tube is a gas outlet, and the gas inlet end of the gas passage corresponds to the gas outlet.

[0005] In one or more embodiments, the mounting portion has three sidewalls that respectively abut against the left side, top side, and right side of the second tube.

[0006] In one or more embodiments, the top side of the second tube is provided with an upwardly extending column, and the column has a threaded hole for screw connection.

[0007] In one or more embodiments, the air passage has an air inlet on one side of the air outlet end, and the air inlet corresponds to the ignition end of the ignition needle.

[0008] In one or more embodiments, a third tube parallel to the first tube is provided on the left side of the valve body. The third tube is connected to the valve core cavity through a gas distribution pipe, and the front end of the third tube is flush with the front end of the first tube.

[0009] In one or more embodiments, the valve body, the first pipe body, the second pipe body, the third pipe body, and the gas distribution pipe are integrally formed by die casting.

[0010] Compared with the prior art, the advantages of this invention are: by designing the mounting part of the frame to have at least three side walls that are tightly fitted to the outer wall of the second tube, forming a multi-faceted contact and wrapping fixing structure, the contact area and connection strength between the frame and the valve body are effectively increased. Compared with the traditional single-point screw fixing method, this structure can better resist vibration and impact during use, preventing the frame from loosening or shifting, thereby ensuring the long-term accuracy and stability of the ignition needle position.

[0012] This section will describe in detail the specific embodiments of the present utility model. The preferred embodiments of the present utility model are shown in the accompanying drawings. The purpose of the drawings is to supplement the textual description with graphics, so that people can intuitively and vividly understand each technical feature and the overall technical solution of the present utility model, but they should not be construed as limiting the scope of protection of the present utility model.

[0013] See appendix Figure 1-2 This application provides an ignition assembly installation structure for a gas valve, which includes a valve body 1, a frame 2, and an ignition needle 3. A first tube 4 is provided on the front side of the valve body 1, and a second tube 5 is provided on the top of the valve body 1 above the first tube 4. A valve core cavity is provided inside the valve body 1, connecting the first tube 4 and the second tube 5. The ignition needle 3 is fixed to the frame 2. A gas passage 6 is provided on the frame 2. The ignition end of the ignition needle 3 corresponds to the gas outlet end 61 of the gas passage 6. The frame 2 is provided with an installation part that connects to the second tube 5. The installation part has at least three side walls 7 that fit against the outer wall of the second tube 5. The installation part is fixed to the second tube 5 by screws 8. The front end face of the second tube 5 is a gas outlet 9. The gas inlet end 62 of the gas passage 6 corresponds to the gas outlet 9. This solution forms a multi-faceted contact, wrapped fixing structure by setting an installation part with at least three side walls 7 that fit against the outer wall of the second tube 5, which greatly increases the connection contact area between the frame 2 and the valve body 1. This ensures the long-term precise fixation of the ignition needle 3, preventing ignition failure, delay, or partial ignition caused by loosening or displacement of the frame 2, thus improving ignition reliability and the safety of the gas stove. The mounting section has three sidewalls 7 that respectively fit into the left side, top side and right side of the second tube 5, forming a more specific and stable U-shaped structure.

[0014] The top side of the second tube 5 is provided with an upwardly extending column 10. The column 10 has a threaded hole for screw 8 to be connected. The upwardly extending column with threaded hole on the top side of the second tube provides a dedicated and sturdy mounting base for screw 8 connection. This design allows the tightening force of screw 8 to act directly on a protruding load-bearing structure, avoiding the problems of stripping or loose connection that may be caused by screws being directly screwed into thinner tube walls, thus improving the durability and reliability of the connection.

[0015] The gas duct 6 has an air inlet 11 on one side of the air outlet 61. The air inlet 11 corresponds to the ignition end of the ignition needle 3. Outside air can enter through the air inlet 11, which helps to fully combust the gas and optimizes the gas-air mixture ratio at the ignition point, thereby potentially improving the ignition success rate and promoting the formation of a more stable flame. The valve body 1 has a third pipe 12 on its left side, parallel to the first pipe 4. The third pipe 12 is connected to the valve core cavity through a gas distribution pipe 13. The front end of the third pipe is flush with the front end of the first pipe. By setting the third pipe 12 parallel to the first pipe 4 and connecting it to the valve core cavity through the gas distribution pipe 13, the distribution of gas to multiple burners is realized, thus expanding the function of the valve body. The valve body 1, the first pipe body 4, the second pipe body 5, the third pipe body 12, and the gas distribution pipe 13 are integrally formed by die casting. The valve body and each pipe body are manufactured by die casting integral forming process, which eliminates the connection gaps and leakage points that may exist in the splicing of multiple parts, and greatly improves the airtightness and safety of the product.

[0016] The above description is only a preferred embodiment of the present utility model. The protection scope of the present utility model is not limited to the above embodiments.
