Abstract
Description
Technical Field
[0001] This utility model relates to the field of gas stove igniter technology, specifically to a gas stove igniter shell structure. Background Technology
[0002] Most existing gas stove igniters are pulse ignition types, and early gas stoves relied on manual ignition, posing safety hazards. Electronic pulse ignition technology, with its high reliability, automated operation, and safety protection, has become a standard feature in modern stoves.
[0003] Existing gas stove igniters are all split-type, with two sets of housings connected and fixed by screws. However, this connection method is troublesome to disassemble and assemble. At the same time, the split structure cannot guarantee the sealing of the connection points, especially where the wiring passes through. During daily use, liquids such as oil or water can easily seep in, which may cause water accumulation inside the igniter and lead to short circuits. Utility Model Content
[0004] (a) Technical problems to be solved In view of the above-mentioned shortcomings of the existing technology, the present invention provides a shell structure for a gas stove igniter, which can effectively solve the problems of the existing technology.
[0005] (II) Technical Solution To achieve the above objectives, this utility model employs the following technical solution: This utility model discloses a gas stove igniter shell structure, including a chamber shell and a cover shell. The chamber shell has symmetrically arranged screw-hole mounting seats at its left and right ends. Two sets of locking blocks are symmetrically arranged at the upper end of the chamber shell. Two sets of limiting strips are symmetrically arranged at the upper end of the cover shell, with a locking groove adapted to the locking blocks at the end of the limiting strip near the chamber shell. Two sets of threaded openings are symmetrically arranged at the lower ends of both the chamber shell and the cover shell. The threaded openings at the lower ends of the chamber shell and the cover shell are fitted together and connected by a threaded sleeve. A fine limiting groove and a coarse groove are respectively provided at the upper and lower ends of the chamber shell and the cover shell. A grooved rubber pad and a convex rubber pad are embedded and bonded within the opening edge on opposite sides of the chamber shell and the cover shell. A limiting component is provided on the upper inner wall of the chamber shell. A sealing component is provided within the coarse groove at the lower end of the chamber shell and the cover shell.
[0006] Furthermore, the longitudinal section of the card block is a right-angled triangle, the inner diameter of the card slot is adapted to the outer diameter of the card block, the end edge of the limiting strip near the housing is rounded, and the upper corner of the card block is rounded.
[0007] Furthermore, both the grooved rubber pad and the convex rubber pad are provided with a grooved rubber pad at their upper ends that is adapted to the fine limiting groove. The grooved rubber pad is located inside the fine limiting groove, and the inner wall of the grooved rubber pad is provided with sealing convex strips with a longitudinal arc shape at equal intervals.
[0008] Furthermore, the limiting component includes a clamping plate and positioning holes formed on the clamping plate. The clamping plate is provided with arc-shaped slots opposite to the fine limiting grooves. The positioning holes are located at both ends of the clamping plate and in the gap between the arc-shaped slots on the clamping plate.
[0009] Furthermore, the sealing assembly includes a rubber sleeve, the upper outer diameter of which is adapted to the inner diameter of the coarse wire groove, a slot is provided in the coarse wire groove, and inserts adapted to the slots in the coarse wire groove are provided at both ends of the rubber sleeve, and the lower outer diameter of the rubber sleeve is adapted to the inner diameter of the threaded opening.
[0010] Furthermore, the lower end of the rubber sleeve is provided with two sets of convex clamping rings, and the diameter of the convex clamping rings increases from bottom to top. The inner diameter of the convex clamping rings is the same as the inner diameter of the rubber sleeve, and the maximum outer diameter of the convex clamping rings is greater than the outer diameter of the threaded opening.
[0011] (III) Beneficial Effects Compared with the known prior art, the technical solution provided by this utility model has the following beneficial effects: By fastening the locking block with the slot on the limit strip and then screwing the threaded sleeve onto the threaded opening, the housing and cover can be connected and locked. This operation is simple and convenient, requiring no tools, and is more convenient and damage-free than screw installation during disassembly and assembly. In addition, the grooved and convex rubber gaskets can seal the connection between the housing and cover, and the grooved rubber gasket and sealing convex strip can wrap around the point where the control power cable exits from the narrow limit groove, achieving a seal. Combined with the positioning and clamping of the limit component, it prevents the cable from being pulled and shifted. This not only protects the cable connection but also prevents the cable from shifting relative to the grooved rubber gasket and sealing convex strip, thus ensuring the preset sealing effect. The rubber sleeve, together with the convex strip clamp, can be fitted onto the ignition wire. After the threaded sleeve is tightened onto the threaded opening, the convex strip clamp will be squeezed inward and tightly fit the ignition wire, thereby clamping the ignition wire. This not only provides anti-pull protection for the ignition wire, but also ensures the connection seal, effectively reducing the possibility of water or oil seeping into the housing and cover through the gap in the cable.

[0015] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some, not all, of the embodiments of this utility model. All other embodiments obtained by those skilled in the art based on the embodiments of this utility model without creative effort are within the scope of protection of this utility model.
[0016] Please see Figure 1-7 This utility model provides an embodiment of a gas stove igniter shell structure, including a housing 1 and a cover 3. Screw-hole mounting bases 2 are symmetrically arranged at the left and right ends of the housing 1. Two sets of locking blocks 4 are symmetrically arranged at the upper end of the housing 1. Two sets of limiting strips 5 are symmetrically arranged at the upper end of the cover 3, and a slot 6 adapted to the locking block 4 is opened at the end of the limiting strip 5 near the housing 1. Two sets of threaded openings 7 are symmetrically arranged at the lower ends of both the housing 1 and the cover 3. The threaded openings 7 at the lower ends of the housing 1 and the cover 3 are fitted together and connected by a threaded sleeve 8. Fine limiting grooves 9 and coarse grooves 10 are respectively opened at the upper and lower ends of the housing 1 and the cover 3. A grooved rubber pad 11 and a convex rubber pad 12 are embedded and glued into the opening edge on the opposite side of the housing 1 and the cover 3. A limiting component is provided on the upper inner wall of the housing 1. A sealing component is provided in the coarse groove 10 at the lower end of the housing 1 and the cover 3.
[0017] As a preferred embodiment of this example, Figure 3 As shown, the longitudinal section of the card block 4 is a right triangle, the inner diameter of the card slot 6 is adapted to the outer diameter of the card block 4, the end edge of the limiting strip 5 near the shell 1 is rounded, and the upper corner of the card block 4 is rounded.
[0018] This structure allows the upper sides of the housing 1 and the cover 3 to be connected after the limiting strip 5 is fitted onto the locking block 4 through the slot 6. Then, the threaded sleeve 8 is fitted onto the two sets of threaded openings 7 to fix the connection between the housing 1 and the cover 3. When the limiting strip 5 is fitted onto the locking block 4 through the slot 6, the vertical surface of the locking block 4 can be prevented from coming out of the slot 6 after the connection is completed, and the locking effect is guaranteed. The rounded corners of the end of the limiting strip 5 and the upper corner of the locking block 4 facilitate guiding and positioning during the fitting process.
[0019] As a preferred embodiment of this example, Figure 4 and Figure 5 As shown, the upper ends of the groove-shaped rubber pad 11 and the convex rubber pad 12 are both provided with a grooved rubber pad 13 that is adapted to the fine limiting groove 9. The grooved rubber pad 13 is located in the fine limiting groove 9, and the inner wall of the grooved rubber pad 13 is provided with sealing convex strips 14 with a longitudinal section of arc shape at equal intervals.
[0020] This structure allows the cable tray pad 13 to fit against the outer wall of the cable, thereby sealing the connection of the cable in the fine limiting groove 9. At the same time, after the housing 1 and the cover 3 are connected and fitted, the sealing protrusion 14 will fit tightly against the outer wall of the cable due to compression, thus ensuring the sealing effect.
[0021] As a preferred embodiment of this example, Figure 4 As shown, the limiting component includes a clamping plate 15 and a positioning hole 16 formed on the clamping plate 15. The clamping plate 15 is provided with an arc-shaped groove opposite to the fine limiting groove 9. The positioning hole 16 is provided at both ends of the clamping plate 15 and in the gap of the arc-shaped groove on the clamping plate 15.
[0022] This structure is used to clamp and position the cable that passes through the narrow limiting groove 9 from the inside, so that the cable can be clamped on the upper inner wall of the housing 1, and the cable will pass through the narrow limiting groove 9 at a 90-degree angle. With the wrapping and clamping of the cable groove rubber pad 13 and the sealing protrusion 14, it can play a certain role in fixing and limiting the cable, so as to prevent the connection between the cable and the component from being affected by the tension when the cable is pulled and thus breakage. At the same time, it can ensure that the connection and sealing effect of the cable groove rubber pad 13 and the sealing protrusion 14 are not affected by the displacement of the cable.
[0023] As a preferred embodiment of this example, Figure 6 and Figure 7As shown, the sealing assembly includes a rubber sleeve 17. The outer diameter of the upper end of the rubber sleeve 17 is adapted to the inner diameter of the coarse wire groove 10. A slot is provided at the coarse wire groove 10. Inserts 18 adapted to the slots in the coarse wire groove 10 are provided at both ends of the rubber sleeve 17. The outer diameter of the lower side of the rubber sleeve 17 is adapted to the inner diameter of the threaded opening 7.
[0024] This structure is used to achieve a sealing effect at the coarse wire groove 10 through the rubber sleeve 17, so as to ensure the sealing of the connection where the ignition wire passes through the coarse wire groove 10, and to facilitate disassembly and assembly.
[0025] As a preferred embodiment of this example, Figure 6 and Figure 7 As shown, the lower end of the rubber sleeve 17 is provided with two sets of convex strip clamping rings 19, and the diameter of the convex strip clamping rings 19 increases from bottom to top. The inner diameter of the convex strip clamping rings 19 is the same as the inner diameter of the rubber sleeve 17, and the maximum outer diameter of the convex strip clamping rings 19 is greater than the outer diameter of the threaded opening 7.
[0026] This structure allows the threaded sleeve 8 to be fitted onto the convex clamp ring 19 from below and tightened onto the threaded opening 7. Because the outer diameter of the convex clamp ring 19 is larger than the outer diameter of the threaded opening 7, and the threaded sleeve 8 and the threaded opening 7 are connected in a sealed manner, the inner diameter of the threaded sleeve 8 is adapted to the outer diameter of the threaded opening 7. Thus, when the threaded sleeve 8 is fitted onto the threaded opening 7, the convex clamp ring 19 will be squeezed inward, thereby wrapping and clamping the ignition wire, achieving the effect of fixing and sealing, so as to reduce the impact on the connection between the ignition wire and the components inside the housing 1 when the ignition wire is pulled.
[0027] Working principle: When in use, pass the power control cable through the fine limiting groove 9 on the housing 1 and let it fit into the cable groove pad 13 on the housing 1. Then, attach the clamp 15 to the cable and press the cable against the upper inner wall of the housing 1 using the clamp 15. Finally, insert the screw into the positioning hole 16 and tighten the clamp 15 to fix it on the upper inner wall of the housing 1.
[0028] Fit the ignition wire with a rubber sleeve 17 and a threaded sleeve 8, and insert the insert block 18 on the rubber sleeve 17 into the slot in the coarse wire groove 10, so that the lower side of the rubber sleeve 17 is inside the threaded opening 7, and the convex strip clamping ring 19 is below the threaded opening 7. Then, fasten the retaining groove 6 on the limiting strip 5 to the retaining block 4, and fit the cover shell 3 and the chamber shell 1 together, so that the threaded openings 7 on the lower side of the chamber shell 1 and the cover shell 3 are fitted and aligned. Finally, tighten the threaded sleeve 8 to fix the corresponding threaded openings 7 on the lower side of the chamber shell 1 and the cover shell 3 through the threads.
