Description

Technical Field

[0001] This invention relates to the field of gas appliance ignition technology, and more particularly to a direct-insertion ignition device suitable for dual-purpose stoves. Background Technology

[0002] In existing electric igniters, due to the high-temperature characteristics of the furnace body, the igniter is usually located far from the furnace body to prevent the insulation material from melting and failing due to the high temperature of the furnace body during long-term use. The specific reason is that the high-voltage discharge needle is located inside the combustion chamber of the furnace body, and the high temperature of combustion is directly transferred to the discharge needle and then conducted to the igniter via the wiring harness. Therefore, existing electric igniters use a wire to connect to the high-voltage discharge needle. The wire between the high-voltage discharge needle and the igniter needs to extend a long distance, but an excessively long wire will affect the pulse ignition energy, causing unstable high-voltage discharge; moreover, it is susceptible to electromagnetic interference or mechanical wear. Summary of the Invention

[0003] In order to address the shortcomings of existing igniters and high-voltage discharge needles that require long-distance wire connections to solve heat insulation issues, this invention provides a direct-insertion ignition device for a dual-purpose furnace.

[0004] The technical solution adopted in this invention is as follows: a direct-insertion ignition device for a dual-purpose furnace, comprising an igniter, and a high-voltage discharge needle and a grounding needle disposed on the furnace body. The igniter includes an igniter housing, a high-voltage interface on the igniter housing, and a grounding interface on the igniter housing. The high-voltage interface is a high-voltage socket that is inserted into the high-voltage discharge needle. A transformer coil is disposed inside the igniter housing. The high-voltage end of the transformer coil is electrically connected to a conductive insert at the high-voltage socket, and the other end is electrically connected to a conductive insert inside the grounding interface. The high-voltage end and the conductive insert are electrically connected through conductive rubber.

[0005] Furthermore, the high-voltage interface and the grounding interface are arranged in a staggered manner, and the grounding interface and the grounding pin are connected by a wire harness.

[0006] Furthermore, it also includes a fixing plate for fixing to the furnace body, the middle of the high-voltage discharge needle is wrapped with insulating material, and the high-voltage discharge needle and the grounding needle are fixed on the fixing plate.

[0007] Furthermore, for ease of fixation, the fixing pin is directly formed by folding a fixing plate, and the side of the high-voltage interface is provided with a fixing socket for insertion into the fixing pin. The height of the fixing pin is lower than that of the insulating material.

[0008] Furthermore, the igniter housing includes an igniter output terminal with a high-voltage interface and a grounding interface at one end, a transformer terminal protruding downward in the middle, and an igniter input terminal at the other end. The input terminal has a first chamber containing a circuit board, which is inverted and mounted on the receiving cavity. The transformer terminal has a second chamber containing a transformer coil. The input terminal of the transformer coil is plugged into and soldered to the output terminal of the circuit board. The output terminal of the transformer coil extends upward and then bends into the igniter output terminal. The high-voltage terminal and the grounding terminal of the transformer coil output terminal extend parallel to each other for the same length. The grounding terminal of the transformer coil output terminal is connected to a conductive component. The high-voltage terminal of the transformer coil output terminal is connected to a conductive rubber component by means of conductive rubber and a conductive insert.

[0009] Furthermore, the first chamber and the second chamber are separated by a partition, and the first chamber is covered with a cover plate.

[0010] Furthermore, the igniter is filled with insulating material, which encapsulates the transformer coil and conductive rubber.

[0011] The advantages of this invention are as follows: it eliminates the need for a long wire in conventional igniters, allowing them to be directly installed on the furnace body; the use of conductive rubber for connection effectively blocks the high temperature transferred from the high-pressure ignition needle; it greatly solves the installation problem of the ignition device, which can be directly inserted into the furnace body; the igniter is arranged directly with the furnace body, eliminating the need for installation layout space in other locations and saving internal space for electrical installation.

A transformer coil is housed within the igniter housing. The high-voltage end of the transformer coil is electrically connected to a conductive insert at the high-voltage plug, and the other end is electrically connected to a conductive insert within the grounding interface. The high-voltage end and the conductive insert are electrically connected via conductive rubber. The igniter is filled with insulating material, which encapsulates the transformer coil and the conductive rubber. The insulating material encapsulates the conductive rubber, forming a cylindrical space. An electric arc is reflected on the inner surface of this cylindrical space, disregarding the resistance of the conductive rubber.

[0018] In this embodiment, to prevent arcing between interfaces, the high-voltage interface and the grounding interface are staggered, and the grounding interface and the grounding pin are connected by a wire harness.

[0021] In this embodiment, the igniter housing includes an igniter output terminal with a high-voltage interface and a grounding interface at one end, a transformer terminal protruding downward in the middle, and an igniter input terminal at the other end. The input terminal has a first chamber containing a circuit board, which is inverted and mounted on the receiving cavity. The transformer terminal has a second chamber containing a transformer coil. The input terminal of the transformer coil is plugged into and soldered to the output terminal of the circuit board. The output terminal of the transformer coil extends upward and then bends into the igniter output terminal. The high-voltage terminal and the grounding terminal of the transformer coil output terminal extend parallel to each other for the same length. The grounding terminal of the transformer coil output terminal is connected to a conductive component. The high-voltage terminal of the transformer coil output terminal is connected to a conductive rubber component by means of conductive rubber and a conductive insert.

[0022] In this embodiment, the first chamber and the second chamber are separated by a partition, and the first chamber is covered with a cover plate.
