Specifically, the use of terms such as "in some embodiments," "exemplarily," and "for example" is intended to present the relevant concepts in a specific manner, meaning that a particular feature, structure, or characteristic described in connection with the embodiments may be included in at least one embodiment of this application.

[0023] Those skilled in the art can understand the specific meaning of the above terms in this application based on the specific circumstances.

[0024] Regarding the accompanying drawings of this application, it should be clearly understood that the drawings are for illustrative and descriptive purposes only and are not intended to limit the scope of this specification. It should also be understood that the drawings are not necessarily drawn to scale.

[0025] like Figures 1 to 5 As shown, this application provides a simple gas stove ignition switch, including a housing 1 and a rotating base 2 rotatably disposed on the housing 1. The housing 1 includes a base 9 and a top cover, which can be detachably fixed by buckles or screws for easy maintenance.

[0026] The housing 1 has a hollow connecting shaft portion 5 integrally formed in the center. The rotating base 2 has a shaft hole at its center that fits the connecting shaft portion 5, allowing the rotating base 2 to rotatably fit over the connecting shaft portion 5 through this shaft hole. For ease of operation, the top of the rotating base 2 has an operating hole 6 coaxial with the connecting shaft portion 5, allowing tools such as screwdrivers and levers to be inserted to drive the rotating base 2 to rotate around the axis of the connecting shaft portion 5. Exemplarily, the operating hole 6 is a polygonal hole or a non-rotating shape.

[0027] The housing 1 is provided with a moving contact 3 and a stationary contact 4, both of which are made of conductive metal. The outer peripheral wall of the rotary seat 2 is provided with a circumferential linkage surface 200. The circumferential linkage surface 200 has a groove 201. The circumferential linkage surface 200 is a circular contour surface. The groove 201 is a concave arc segment of the circular contour surface. The circumferential span of the concave arc segment is 45°-75°. In this application, 60° is preferred, which ensures the accuracy of gear switching and avoids the rotary seat 2 from rotating too much, which would cause inconvenience in operation.

[0028] To prevent the linkage from jamming when the rotating seat 2 rotates, the two ends of the concave arc segment are smoothly transitioned to the circular contour surface. The radius of the transition fillet is preferably 0.5-1mm, so that when the linkage 301 slides along the circumferential linkage surface 200, it can smoothly enter or disengage from the groove 201.

[0029] The movable contact 3 includes a positioning part 300, a linkage part 301, and a contact part 302 integrally formed and connected in sequence. The positioning part 300 is fixed to the housing 1. The linkage part 301 slides against the circumferential linkage surface 200. For example, the contact part 302 is a ridge-shaped structure formed by bending the movable contact 3 toward the stationary contact 4. This structure allows the contact part 302 to form a transition from line contact to surface contact when it contacts the stationary contact 4, which not only increases the contact pressure and ensures reliable conduction, but also avoids excessive wear caused by single-point contact.

[0030] The stationary contact piece 4 and the contact portion 302 are arranged at a radial distance along the rotating base 2. Preferably, the stationary contact piece 4 and the positioning portion 300 of the moving contact piece 3 are arranged in parallel.

[0031] When the linkage part 301 is inserted into the groove part 201, the contact part 302 separates from the stationary contact piece 4 to form a disconnected state; when the linkage part 301 is disengaged from the groove part 201, the contact part 302 contacts the stationary contact piece 4 to form a conductive state.

[0032] To prevent poor contact due to loose contact, the base 9 is provided with a first groove 11 for positioning the moving contact 3, a second groove 12 for positioning the stationary contact 4, and a movable groove 13 for the linkage part 301 and the contact part 302 to move, reserving space for deformation of the moving contact 3. The upper cover is provided with a third groove 18 for positioning the moving contact 3 and a fourth groove 19 for positioning the stationary contact 4. The base 9 is provided with a first wire 14 and a second wire 15 on both sides of the rotating base 2. The moving contact 3 is provided with a first snap-fit ​​hole 16 for the first wire 14 to pass through, and the stationary contact 4 is provided with a second snap-fit ​​hole 17 for the second wire 15 to pass through. The part of the moving contact 3 with the first snap-fit ​​hole 16 is embedded in the third groove 18, and the part of the stationary contact 4 with the second snap-fit ​​hole 17 is embedded in the fourth groove 19. The stability of the fixed end of the contact is improved by the bidirectional clamping of the grooves in the base and the grooves in the upper cover.

[0033] To ensure the reliability of the wire connection and avoid poor contact caused by wire pulling, the base 9 is provided with a first lower positioning groove 20 for the first wire 14 to pass through and a second lower positioning groove 21 for the second wire 15 to pass through on both opposite sides. The top cover is provided with a first upper positioning groove 22 for the first wire 14 to pass through and a second upper positioning groove 23 for the second wire 15 to pass through on both sides in the same direction. Each positioning groove is a U-shaped groove. The first lower positioning groove 20 and the first upper positioning groove 22 are matched to form a first clamping hole 24 for clamping the first wire 14. The second lower positioning groove 21 and the second upper positioning groove 23 are matched to form a second clamping hole 25 for clamping the second wire 15. The wire is initially fixed by the clamping force of the clamping hole.

[0034] Furthermore, the clamping surfaces of the first lower positioning groove 20 and / or the first upper positioning groove 22 are provided with positioning teeth 26, and the clamping surfaces of the second lower positioning groove 21 and / or the second upper positioning groove 23 are provided with positioning teeth 26. The positioning teeth 26 can press the insulation layer surface of the wire, increase the friction force, and prevent the wire from being pulled loose along the axial direction. It can be understood that each positioning groove has two teeth, and at least one of them is provided with positioning teeth 26. Multiple positioning teeth 26 are evenly arranged circumferentially along the corresponding clamping surfaces.

[0035] Furthermore, the upper cover is provided with pressure blocks 100 near the first upper positioning groove 22 and the second upper positioning groove 23. The pressure blocks 100 press against the corresponding wires, and the side that presses against the corresponding wires is provided with an arc-shaped surface, which not only avoids radial shaking of the wires, but also prevents excessive clamping force from damaging the wire insulation layer.

[0036] It is understandable that multiple rotary switches can be connected to the same first wire 14 and second wire 15.

[0037] To ensure stable on / off states of the switch and prevent accidental rotation of the rotary base 2 due to vibration, a positioning groove 7 is provided at the bottom of the rotary base 2, and an elastic arm 8 is provided at the bottom of the housing 1. A positioning block 80 adapted to the positioning groove 7 is provided on the free end of the elastic arm 8. The positioning block 80 is located on the rotation path of the positioning groove 7. When in the off state, the positioning block 80 is embedded in the positioning groove 7. Specifically, the elastic force of the elastic arm 8 pushes the positioning block 80 into the positioning groove 7, forming a position lock to prevent the rotary base 2 from rotating accidentally. When it is necessary to switch to the on state, an external force is applied to rotate the rotary base 2, and the positioning block 80 overcomes the elastic force of the elastic arm 8 and disengages from the positioning groove 7, achieving a smooth switch.

[0038] Preferably, the top of the positioning block 80 and the bottom wall of the positioning groove 7 are both arc-shaped to reduce friction when the rotating seat 2 rotates.
