Description

Technical Field

[0001] This application relates to the field of gas safety control, and more specifically, to a flameout protection ignition controller. Background Technology

[0002] The flameout protection ignition controller is a core safety control component in gas appliances such as gas-fired griddles, gas-fired steamers, and gas-fired barbecue grills. Its working principle is to monitor the flame ionization signal and automatically cut off the gas supply in the event of accidental flameout, thereby preventing gas leaks and ensuring the safety of operators.

[0003] Existing flameout protection ignition controllers on the market typically consist of two parts: an internal electronic control module and an external housing. The housing primarily serves to encapsulate and protect the device, provide electrical insulation, prevent moisture and oil contamination, and ensure proper mounting.

[0004] The outer casing is typically divided into a top cover and a bottom cover, which are connected and fixed by multiple screws. The advantage of this method is that the connection is firm, the sealing is good, and it can effectively prevent non-professionals from opening it at will. However, its disadvantages are also very obvious. During maintenance or replacement of wires, operators need to use a special screwdriver to remove the screws one by one. After maintenance or replacement of wires, multiple screws need to be tightened again with a screwdriver. This method of removing screws is too time-consuming and laborious. Utility Model Content

[0031] Reference Figure 1-5 ,

[0032] A flameout protection ignition controller includes: a controller body 1 and a cover plate 2; the controller body 1 has a first connection port 11 for a wire 3 to pass through, a second connection port 12, a first inspection port 13 communicating with the first connection port 11, and a second inspection port 14 communicating with the second connection port 12; two cover plates 2 are provided, both of which are snapped into the controller body 1, one cover plate 2 is used to block the first inspection port 13, and the other cover plate 2 is used to block the second inspection port 14. Operators do not need to use a screwdriver to loosen multiple screws; they can quickly open or close the first inspection port 13 and the second inspection port 14 with simple operations to connect, replace, and repair the wire 3, saving time and effort.

[0033] Specifically, the cover plate 2 has a connecting plate that connects to the controller body 1. The connecting plate has a protrusion, and the controller body 1 has a groove inside that matches the shape of the protrusion. The protrusion and the groove are engaged and fixed together. The side of the cover plate 2 facing away from the controller body 1 has an anti-slip protrusion to increase the friction between the operator's hand and the cover plate 2, allowing the operator to easily open the cover plate 2. In other embodiments, a connecting rope is fixed to the side of the cover plate 2 facing away from the controller body 1. The connecting rope has a strip-like structure, and a connecting ring is provided at the end of the connecting rope facing away from the cover plate 2. The operator can detach the cover plate 2 from the controller body 1 by pressing the cover plate 2 and pulling the connecting ring. See the attached diagram for details. Figure 5 .

[0034] Specifically, the flameout protection ignition controller also includes: a circuit board 4 and a terminal block 5; the circuit board 4 is fixed inside the controller body 1 by screws, and the terminal block 5 is electrically connected to the circuit board 4; the terminal block 5 is used to connect multiple wires 3; specifically, the terminal block 5 has multiple independent wiring positions, each of which provides an independent connection point. By fixing the multiple wires 3 individually to the independent wiring positions, the wires 3 can be electrically connected to the circuit board 4. The terminal block 5 is existing technology and will not be described in detail. The terminal block 5 is located on the circuit board 4 near the first connection port 11, and the first inspection port 13 covers the terminal block 5, ensuring that the operator can see the terminal block 5 when opening the cover 2, which is beneficial for the operator to perform replacement and maintenance work, and improves the efficiency of maintenance or replacement.

[0035] Specifically, the controller body 1 has a first extension 15, and a second extension 21 is provided on one of the cover plates 2; both the first extension 15 and the second extension 21 are plate-shaped structures. The first extension 15 and the second extension 21 extend outward from the controller body 1; a first connection port 11 is formed between the first extension 15 and the second extension 21. The arrangement of the first extension 15 and the second extension 21 can guide and support the wires 3 connected to the controller body 1, and at the same time, it can also prevent the wires 3 from being cut by the sharp edges of the cover plate 2 or the controller body 1 at the first connection port 11, thereby improving a certain degree of safety.

[0036] Specifically, the controller body 1 has a first extension 16, and another cover plate 2 has a second extension 22; both the first extension 16 and the second extension 22 are arc-shaped plate structures. Specifically, multiple first extensions 16 are provided on the controller body 1, and multiple second extensions 22 are provided on the cover plate 2, with the number of first extensions 16 being the same as the number of second extensions 22. In this embodiment, four first extensions 16 and four second extensions 22 are provided. The first extensions 16 and the second extensions 22 extend outwards from the controller body 1, forming a second connection port 12 between them. The arrangement of the first extensions 16 and the second extensions 22 can guide and support the wires 3 connected to the controller body 1, and also prevent the wires 3 from being cut by the sharp edges of the cover plate 2 or the controller body 1 at the second connection port 12, thus improving safety.

[0037] Specifically, wire 3 includes an ignition wire, a detection wire, a power supply wire, a grounding wire, an alarm light wire, a solenoid valve wire, and a fan wire. The diameters of the power supply wire, grounding wire, alarm light wire, solenoid valve wire, and fan wire are all smaller than the diameters of the ignition wire and the detection wire. One end of the power supply wire, grounding wire, alarm light wire, solenoid valve wire, and fan wire passes through the first connection port 11 and connects to the terminal block 5. The ignition wire and the detection wire pass through the second connection port 12 and are electrically connected to the circuit board 4. The ignition wire must maintain a distance of at least 10mm from other electronic components / wires.

[0038] Specifically, the controller body 1 has multiple heat dissipation holes 17 on both sides. The heat dissipation holes 17 form an air convection channel, which can effectively dissipate the heat inside the controller body 1 and prevent the controller body 1 from overheating and causing damage to the circuit board 4.

[0039] Specifically, the controller body 1 has connection holes 18 on both sides for fixing the controller body 1. Operators can use screws or other fasteners to securely install the controller body 1 into gas appliances such as gas griddles, gas steamers, and gas barbecue grills.

[0040] Specifically, the first inspection port 13 is provided with a guide portion 141; the guide portion 141 has a plate-like structure. The guide portion 141 extends from one end of the first connection port 11 to the other end of the first connection port 11; the guide portion 141 is used to guide and limit the cover plate 2; the first inspection port 13 and the second inspection port 14 have the same structure. The guide portion 141 can guide the cover plate 2 to be installed in the correct direction, preventing the cover plate 2 from being installed crookedly or misaligned.

[0041] Specifically, when the cover plate 2 comes into contact with the guide part 141, the side of the cover plate 2 facing away from the guide part 141 is flush with the controller body 1, so that after the cover plate 2 is snapped and fixed to the controller body 1, the surface of the controller body 1 has no protrusions or depressions, making the controller body 1 more aesthetically pleasing.
