Description

Technical Field

[0001] This utility model belongs to the field of gas stove controllers, specifically, it relates to a gas stove controller with seamless switching function. Background Technology

[0002] A gas stove control system typically consists of a main control circuit board, a signal acquisition module, and external actuators. Its core function is to provide real-time control and feedback on gas supply, ignition, flame detection, and wind pressure signals. Existing gas stove controllers generally use a structure where the circuit board is fixed inside an injection-molded housing. The circuit board is installed using screws, clips, or soldering and is electrically connected to the display panel, power module, and other components.

[0003] However, in practical applications, existing gas stove control modules mostly rely on screws or clips for installation and maintenance, requiring specialized tools such as screwdrivers and pry bars for disassembly and assembly. Due to the limited size of the controller housing and the compact arrangement of internal circuit boards and wiring harnesses, the operating space is narrow, making it difficult to accurately align tools. Often, repeated angle adjustments are needed to tighten or loosen screws, significantly increasing the difficulty of operation and assembly time. For mass assembly on production lines or after-sales maintenance scenarios, frequent use of tools for disassembly and assembly not only affects work efficiency but may also cause problems such as stripped screws, broken clips, or scratched circuit boards due to improper operation. Therefore, it is evident that existing gas stove control modules rely excessively on tool operation during disassembly and assembly.

[0004] In view of this, this utility model is proposed. Utility Model Content

[0006] To solve the above-mentioned technical problems, the basic concept of the technical solution adopted by this utility model is as follows:

[0007] A gas stove controller with seamless switching function includes: a controller housing, a circuit board installed inside the controller housing, multiple base posts inside the housing, and several through holes through the opposite sides of the circuit board, with locking components for engaging with the base posts inside the through holes;

Detailed Implementation

[0031] The present invention will now be described in further detail with reference to the accompanying drawings.

[0032] Please see Figure 1-7 As shown, this embodiment provides a gas stove controller with seamless switching function, including a controller housing 1, a circuit board 2 installed inside the controller housing 1, multiple base piles 3 arranged inside the housing, and several through holes through the opposite sides of the circuit board 2, with locking components for engaging with the base piles 3 inside the through holes;

[0033] The locking component includes a connecting cylinder 4, with a positioning cylinder 5 connected to the lower part of the connecting cylinder 4. A sliding column 6 is elastically fitted inside the positioning cylinder 5. Two channels are opened on the periphery of the outer wall of the positioning cylinder 5. A ball 7 is movably fitted inside the channels. The end of the channel has an arc-shaped structure with a diameter smaller than that of the ball 7 to prevent the ball 7 from sliding out of the channel. Two annular grooves A8 with arc-shaped cross sections are opened on the periphery of the lower end of the sliding rod. A straight groove adapted to the positioning cylinder 5 is opened above the foundation pile 3. An annular groove B9 adapted to the ball 7 is opened inside the straight groove.

[0034] When the sliding column 6 is in the middle position of the connecting cylinder 4, the ball 7 is precisely located between the two annular grooves A8, in a convex state constrained by the groove section. At this time, the outer side of the ball 7 protrudes from the outer wall of the positioning cylinder 5, thus engaging with the annular groove B9 on the inner side of the foundation pile 3, achieving stable locking and positioning. When the sliding column 6 moves axially downward or upward, the annular groove A8 moves accordingly with the sliding column 6. Under the guidance of the inclined surface at the end of the sliding column 6 and the inner wall of the groove, the ball 7 undergoes radial displacement, gradually sliding into the interior of the annular groove A8. At this time, the ball 7 is completely inside the groove, no longer protruding outward, releasing the engagement with the annular groove B9, and making the locking element in a releaseable state. Through the bidirectional movable design of the sliding column 6, the ball 7 can automatically disengage or reset during upward or downward movement, thereby realizing the bidirectional triggering quick locking and unlocking function.

[0035] It should be noted that the controller housing 1 includes an upper housing and a lower housing, which are fixedly connected by bolts, and the base pile 3 is fixed to the inner wall of the lower housing.

[0036] Furthermore, a numerical display module is electrically connected to one side of the circuit board 2. The numerical display module adopts an LED screen or a touch screen in the prior art, and an opening adapted to the LED screen is provided on one side of the upper housing.

[0037] In this embodiment, a baffle 10 with a diameter larger than the through hole is fixedly connected to the top of the connecting cylinder 4. A mounting hole is formed through the opposite side of the baffle 10. A damping element is slidably fitted inside the mounting hole, and a sliding rod is located inside the damping element. The damping element includes a cylinder 11 that slides within the mounting hole. Several slots are formed on the circumference of the inner wall of the cylinder 11. A ball-head rod 12 is elastically connected inside each slot. A groove matching the ball-head rod 12 is formed on the circumference of the sliding rod, and the sliding rod and the cylinder 11 are rotatably connected. The damping element uses a structure where the cylinder 11 and the ball-head rod 12 elastically engage, allowing the sliding rod to achieve flexible limiting during rotation or pressing. Through the engagement of the ball-head rod 12 and the groove of the sliding rod, different resistance feedback can be generated at different positions, thereby achieving multi-level pressing feel and positional stability.

[0038] In this embodiment, multiple guide bars 13 are fixedly connected to the lower part of the cylinder 11, and a sliding groove for the guide bars 13 to slide is provided on the upper part of the connecting cylinder 4. A T-shaped annular groove C is fixedly connected to the outer wall of the slide rod, and a rotating ring that slides in the annular groove C is fixedly connected to the upper part of the inner wall of the cylinder 11. Through the cooperation between the annular groove C and the rotating ring, the slide rod and the cylinder 11 form a relatively independent but functionally linked integrated connection relationship in structure. Specifically, the rotating ring is slidably embedded in the annular groove C, which can both limit the axial separation between the slide rod and the cylinder 11 and allow the two to achieve relative rotation or slight floating in a specific direction, thereby achieving flexible linkage while maintaining overall stability. At the same time, the guide bars 13 play a precise linear guiding role for the cylinder 11 during the sliding process, so that the cylinder 11 can only move in a preset direction and avoid synchronous rotation when the slide rod rotates.

[0039] In this embodiment, a sliding plate 14 is fixedly connected to the periphery of the outer wall of the sliding rod 6, and slides within the connecting cylinder 4. Connecting rings 15 are rotatably connected above and below the sliding plate 14. A first spring 16, sleeved around the periphery of the sliding rod, is connected between the side of the connecting ring 15 away from the sliding plate 14 and the inner wall of the connecting cylinder 4. A T-shaped ring body is fixedly connected to the side of the connecting ring 15 facing the sliding plate 14, and annular grooves C for sliding of the ring body are formed on both sides of the connecting plate. The connecting ring 15 effectively isolates the sliding rod from the first spring 16 during rotation. Specifically, the connecting ring 15 serves as an intermediate force transmission element between the sliding rod and the first spring 16. Its inner ring is fixedly connected to the sliding rod, and its outer ring contacts the end of the spring through a bearing-type or gap-type structure. Therefore, when the sliding rod rotates, it only transmits axial pressure and not torque, preventing the first spring 16 from becoming entangled or rotating due to rotational force, thus preventing motion interference and spring fatigue damage. At the same time, a limiting and positioning fit is formed between the ring body and the annular groove C. The ring body can slide in a specific direction within the annular groove C but cannot be dislodged, thus realizing the guiding and position holding functions of the sliding component.

[0040] In this embodiment, a first straight groove 17 and a second straight groove 18 are respectively formed on the upper and lower sides of the inner wall of the connecting cylinder 4, and the first straight groove 17 and the second straight groove 18 are staggered. An arc-shaped groove A19 connects the first straight groove 17 and the second straight groove 18. A connecting block that can slide within the first straight groove 17, the second straight groove 18, and the arc-shaped groove A19 is fixedly connected to one side of the sliding plate 14. The inner wall of the connecting cylinder 4 is provided with the first straight groove 17, the second straight groove 18, and the arc-shaped groove A19, and a sliding structure that can cross the grooves is formed by the connecting block, so that the sliding plate 14 can smoothly transition in multiple directions, forming a multi-level guide path.

[0041] In this embodiment, a pressing plate 20 is fixedly connected to the upper end of the slide rod for easy pressing by a person, and an arc-shaped groove B is provided above the pressing plate 20. The arc-shaped groove B facilitates pressing the pressing plate 20 by a person.

[0042] Example 1: In this example, the locking component is installed using an adhesive fixing method. Specifically, the outer wall of the locking component is uniformly coated with industrial-grade epoxy resin or high-temperature resistant structural adhesive and then inserted into the through hole of the circuit board 2. After the adhesive layer cures, a stable fixed connection is formed. The adhesive force generated after the adhesive cures allows for high-strength positioning without mechanical fasteners, avoiding the accumulation of assembly tolerances caused by threaded or slotted assembly. Subsequently, the lower end of the positioning cylinder 5 is precisely inserted into the straight groove opened on the base pile 3, and the ball 7 is engaged with the annular groove B9, thereby completing the locking process.

[0043] Example 2: In this example, the locking component adopts a bolt-like sliding structure and is installed inside the through hole. The locking component is designed as a combination structure with a guide thread section and a limiting cylinder section, allowing it to slide smoothly along the axial direction in the through hole, achieving adjustable assembly. During assembly, the base pile 3 passes through the through hole from bottom to top and engages with the positioning cylinder 5 of the locking component, thus forming a sliding fit. At this time, the straight groove on the inner side of the base pile 3 has a T-shaped cross-section, and its width matches the outer contour of the connecting cylinder 4 and the positioning cylinder 5, enabling stable locking and limiting.

Anyone should know that structural changes made under the guidance of this utility model, and any technical solutions that are the same as or similar to this utility model, fall within the protection scope of this utility model.
