[0049] In the description of the present invention, unless otherwise clearly defined, terms such as setting, installing, and connecting should be understood in a broad sense, and technicians in the relevant technical field can reasonably determine the specific meanings of the above terms in the present invention based on the specific content of the technical solution.

[0050] Refer to the following Figures 1 to 15 , illustrating an ignition device and a gas stove according to an embodiment of the present invention.

[0051] Reference Figure 1 、 Figure 2 、 Figure 7 and Figure 8As shown, an ignition device according to an embodiment of the present invention includes an igniter, a connector, and an adapter. The igniter includes a housing 101, which is provided with a connection port 201. The adapter includes a connection terminal 103 that passes through the connection port 201 and enters the interior of the housing 101, connecting to the circuit of the igniter. The connection terminal 103 is provided with a slot 401. When the adapter is connected to the igniter, the slot 401 is located inside the housing 101, and the connector is engaged with the slot 401 to prevent the connection terminal 103 from being separated from the connection port 201.

[0052] An igniter is a device that instantly provides enough energy to ignite pulverized coal, oil, or gas fuel and stabilize the flame. It primarily consists of a power supply, ignition coil, distributor, ignition switch, spark plug, additional resistor and short-circuit device, and high and low voltage wires.

[0053] Gas stoves generally use pulse igniters. These electronic devices utilize the pulse principle to generate continuous, instantaneous sparks, thereby igniting the flame of the gas appliance. A pulse igniter is a pulsed high-frequency oscillator composed of electronic components. The high-frequency voltage generated by the oscillator is boosted to a high voltage of 15kV by a step-up transformer. This discharge generates a sharp discharge, and the resulting spark ignites the gas in the burner. This igniter has a high ignition rate and can discharge continuously. Pressing the knob initiates ignition; releasing the knob stops the pulse ignition.

[0054] Early lighters were mostly powered by dry batteries, but in recent years some products have switched to AC power. The AC power source is connected to the lighter via a power adapter.

[0055] A power adapter is a power conversion device for small portable electronic devices and electronic appliances. It is generally composed of components such as a casing, transformer, inductor, capacitor, control IC, and PCB board. It works by converting AC input into DC output. Based on the connection method, it can be divided into wall-mounted and desktop types.

[0056] In the related art, the connection structure between the power adapter and the pulse igniter of the gas stove is an X-type connection structure, that is, the power adapter and the pulse igniter can be directly disassembled, for example, the wiring terminals of the power adapter can be directly unplugged from the pulse igniter without the aid of tools or without the need for professional personnel to disassemble. Gas stoves have been clearly included in 3C products since October 1, 2020. Gas stoves belong to the second category of 3C appliances. The connection interface of the power adapter must be a Y-type structure that can only be disassembled by professionals using tools. The original X-type connection mechanism is no longer applicable.

[0057] The ignition device of the embodiment of the present invention is designed to solve the above-mentioned problem. The ignition device of the embodiment of the present invention clamps the connection terminal 103 of the adapter through the clamping part, so that the user cannot directly remove the adapter from one side of the adapter. If the user needs to disconnect the power supply, he can only unplug the connection between the adapter and the socket. If you want to disconnect the connection between the adapter and the shell 101 of the igniter, only a professional can disassemble the entire gas stove, disassemble the shell 101 of the igniter, and use a tool to push open the clamping part from the other side of the igniter, that is, the inside of the igniter, before removing the adapter. This structure meets the requirements of the 3C standard Y-type structure. At the same time, it can reduce the risk of electric sparks generated when the adapter terminal is directly unplugged, and the risk of combustion and explosion when there is a gas leak in the gas stove.

[0058] Reference Figure 3 and Figure 4 As shown, it can be understood that the shell 101 is provided with a baffle 102, and the connecting terminal 103 is provided with a flat portion 402. The flat portion 402 cooperates with the baffle 102 to prevent the connecting terminal 103 from rotating, thereby ensuring a reliable connection between the connecting terminal 103 and the circuit of the igniter, and avoiding circuit damage or failure caused by torsion.

[0059] Reference Figure 1 、 Figure 2 、 Figure 5 and Figure 6 As shown, it can be understood that the shape of the connection port 201 is rectangular, and correspondingly, the cross-section of the connection terminal 103 is rectangular, that is, the connection terminal 103 is provided with four flat portions 402, and the four flat portions 402 are evenly distributed along the circumference of the connection terminal 103. The housing 101 is also provided with four baffles 102, and the four baffles 102 are arranged in a one-to-one correspondence with the four flat portions 402. This arrangement can limit the rotation of the connection terminal 103 in all four directions, improving stability and reliability. In addition, the four flat portions 402 are evenly distributed along the circumference of the connection terminal 103, so that the connection terminal 103 can be inserted into the connection port 201 of the igniter from four different angles, rather than a single specific angle, which is more convenient for installation.

[0060] It should be noted that only two baffles 102 are provided on the shell 101, and the connecting terminal 103 is provided with two, three or four flat portions 402, and the two baffles 102 are located on opposite sides of the connecting terminal 103; or, only one baffle 102 is provided on the shell 101, one side of the connecting terminal 103 is provided as a flat portion 402, and the other three side surfaces are provided as arc-shaped portions, which can also replace the above-mentioned scheme.

[0061] Reference Figure 3 and Figure 4As shown, it can be understood that the housing 101 is provided with a first guide portion 403 , which can be chamfered or rounded. By providing the first guide portion 403 , the connecting terminal 103 can be conveniently guided into the connecting port 201 .

[0062] Reference Figure 3 and Figure 4 As shown, it can be understood that the clamping member is a buckle 404 set on the baffle 102, that is, the clamping member and the baffle 102 are integrally formed, one end of the baffle 102 is fixedly connected to the shell 101, and the other end of the baffle 102 is provided with a buckle 404, which has a certain elasticity as a whole. After the connecting terminal 103 enters the connecting port 201, the connecting terminal 103 opens the buckle 404 and continues to move toward the inside of the shell 101 until the slot 401 moves to the position corresponding to the buckle 404. At this time, the buckle 404 is buckled in the slot 401 to limit the position of the connecting terminal 103. When the connecting terminal 103 is subjected to external force and wants to be separated from the connecting port 201, the connecting terminal 103 cannot be separated from the connecting port 201 because it is clamped by the undercut 404. That is, the user cannot directly remove the adapter from one side of the adapter. Only a professional can disassemble the entire gas stove, disassemble the igniter shell 101, and use a tool to push open the undercut 404 from the other side of the igniter, that is, the inside of the igniter, to remove the adapter.

[0063] It should be noted that the clip can also be provided separately on the housing 101, with the clip and the baffle 102 provided on different sides of the connection terminal 103, or the clip and the baffle 102 can be provided on the same side of the connection terminal 103 but with the clip higher than the baffle 102. The clip can also be detachably connected to the baffle 102 by means of a screw or other structure.

[0064] Reference Figure 3 and Figure 4 As shown, it is understood that the end of the undercut 404 is provided with a guide structure to facilitate the engagement of the clip with the slot 401. The guide structure can be an inclined surface or an arcuate surface. By providing the guide structure, the end of the connecting terminal 103 can more easily push off the undercut 404, thereby passing over the undercut 404, thereby ensuring that the undercut 404 can more easily enter the slot 401. It is understood that the slot 401 can also be provided with an inclined surface corresponding to the guide structure to guide the undercut 404 to better enter the slot 401.

[0065] Reference Figure 4 and Figure 5 As shown, it is understandable that the end of the connecting terminal 103 is provided with a third guide portion 405. The third guide portion 405 can be chamfered or rounded. By providing the third guide portion 405, the connecting terminal 103 is easier to enter the connecting port 201 and also easier to pass over the undercut 404.

[0066] Reference Figure 5 As shown, it is understood that the bottom wall of the slot 401 is flat, and thus the cross-section of the bottom wall of the slot 401 is rectangular, so as to facilitate cooperation with the four undercuts 404. It should be noted that the bottom wall of the slot 401 can also be in an arc shape, and the side of the undercut 404 facing the bottom wall of the slot 401 can also be set to an arc shape.

[0067] Reference Figure 6 As shown, it can be understood that four baffles 102 are provided on the housing 101 and there is a gap between two adjacent baffles 102 to avoid interference between the two adjacent baffles 102 and affect the connection of the adapter to the igniter.

[0068] Reference Figure 5 As shown, it can be understood that the connecting terminal 103 is provided with four planar portions 402, and the four planar portions 402 are evenly distributed along the circumference of the connecting terminal 103, and an arc portion 501 is provided between two adjacent planar portions 402. After the adapter is connected to the igniter, the arc portion 501 is located between two adjacent baffles 102.

[0069] Reference Figure 7 and Figure 8 As shown, it is understandable that the undercut 404 can also be replaced by a circlip 701. The circlip 701, also called a retaining ring or a snap ring, is a type of fastener that is installed in a shaft groove or a hole groove of a machine or equipment to prevent axial movement of parts on the shaft or hole.

[0070] During assembly, the connecting terminal 103 of the adapter passes through the connecting port 201 of the igniter, and the connecting terminal 103 enters the interior of the shell 101. At this time, the slot 401 is located inside the shell 101, and the retaining spring 701 is clamped in the slot 401. The outer diameter of the retaining spring 701 is larger than the width of the connecting port 201, so that the connecting terminal 103 can be clamped on the shell 101 to prevent the connecting terminal 103 from detaching from the connecting port 201.

[0071] Reference Figure 7 、 Figure 8 and Figure 12 As shown, it can be understood that the housing 101 is provided with only one baffle 102, and baffle 102 is located on one side of the connection port 201. The connection terminal 103 is provided with four flat portions 402. Accordingly, the connection port 201 is rectangular in shape. The baffle 102 and the flat portions 402 cooperate to limit the rotation of the connection terminal 103, thereby ensuring a reliable connection between the connection terminal 103 and the igniter circuit, and preventing circuit damage or failure caused by torsion.

[0072] Reference Figure 7 、 Figure 9 、 Figure 10 、 Figure 11 and Figure 12 As shown, it can be understood that the baffle 102 is located on one side of the connecting terminal 103, and the clamping spring 701 is clamped into the clamping slot 401 from the other side of the connecting terminal 103. The clamping spring 701 surrounds at least three sides of the connecting terminal 103 to better clamp the clamping spring 701 into the clamping slot 401 and to limit the rotation of the connecting terminal 103.

[0073] Reference Figure 14 As shown, it can be understood that the side of the baffle 102 close to the connection port 201 is located in the same plane as the inner wall of the connection port 201. In this way, the baffle 102 can be closer to the connection terminal 103, thereby better restricting the rotation of the connection terminal 103, reducing the shaking of the connection terminal 103, and not blocking the installation of the connection terminal 103.

[0074] Reference Figure 15 As shown, it can be understood that the clamping spring 701 is arc-shaped and has an opening 1501 for the connecting terminal 103 to pass through, so as to be clamped into the clamping slot 401 of the connecting terminal 103. This arrangement can facilitate the clamping spring 701 to open the opening 1501 and clamp into the clamping slot 401. Figure 13 As shown, corresponding to the arc-shaped clamping spring 701 , the bottom wall of the clamping slot 401 is an arc-shaped surface, and the cross section of the bottom wall of the clamping slot 401 is circular.

[0075] Reference Figure 15 As shown, it is understood that the end of the clamping spring 701 is provided with a second guide portion 1502 to facilitate the clamping of the clamping spring 701 to the clamping slot 401. The second guide portion 1502 can be an inclined surface or an arc surface.

[0076] Reference Figure 15 As shown, it can be understood that the width of the clamping spring 701 gradually decreases from the middle to the ends. The width of the clamping spring 701 is the largest in the middle, which is conducive to ensuring the strength of the clamping spring 701, while the width of the clamping spring 701 is the smallest at the ends, which is conducive to achieving elastic deformation at both ends, thereby opening a certain angle and clamping the clamping spring 701 into the slot 401.

[0077] Reference Figure 15 As shown, it is understood that a boss 1503 is provided on the retaining spring 701. During assembly, the boss 1503 facilitates the operator to grasp the retaining spring 701 and thereby facilitates the engagement of the retaining spring 701 with the retaining slot 401. During disassembly, the boss 1503 facilitates the operator to apply force, using a tool to contact the boss 1503 to remove the retaining spring 701.

[0078] Reference Figure 7 and Figure 12As shown, it can be understood that the boss 1503 is arranged opposite to the plane portion 402 of the connecting terminal 103, and the boss 1503 cooperates with the plane portion 402 to prevent the retaining spring 701 from rotating.

[0079] The gas stove according to the embodiment of the present invention includes the ignition device according to the embodiment of the present invention. By adopting the ignition device according to the embodiment of the present invention, the structure of the igniter and the adapter meets the requirements of the 3C standard Y-shaped structure.

[0080] The embodiments of the present invention are described in detail above with reference to the accompanying drawings. However, the present invention is not limited to the above embodiments. Various changes can be made within the knowledge of ordinary technicians in the relevant technical field without departing from the scope of the present invention.
