Description

Coil framework, high-voltage coil and igniter

Technical Field

The invention relates to an igniter, in particular to a coil framework, a high-voltage coil and an igniter.

Background

An igniter is a device which can provide enough energy to ignite pulverized coal and oil (gas) fuel at a moment and can stabilize flame. The igniter is divided into a commercial stove and a civil stove: the commercial ignition device is mainly applied to the kitchen stove ignition system, and the requirement for civil use is relatively strict when the igniter is selected because the use environment of the kitchen is relatively complex. The household stove mainly is used for ignition of household stoves, is simpler in use environment than catering stoves, and has more pulse type ignition.

The existing igniter on the market has high coil breakdown frequency when in use.

Disclosure of Invention

In order to solve the problems, the invention provides a coil framework, a high-voltage coil and an igniter.

The technical scheme of the invention is as follows:

a coil skeleton is characterized in that four pins are inserted into the front face of the coil skeleton, one of the four pins is a grounding pin, one of the four pins is an output pin, and the other of the four pins is an input pin; one end or two ends of the coil framework extend outwards to form a boss for the input pin to be inserted; two input pins are inserted on the boss and far away from the enameled wire.

According to the research, the reason that the coil is broken down is that the high-voltage input pin is too close to the enameled wire; based on this, our modified coil skeleton's structure will insert the input pin on it and keep away from the enameled wire, like this, greatly reduced the frequency that the coil broke down.

The grounding pin and the two input pins are on the same straight line; when the igniter is convenient to assemble, the igniter is connected with the control panel.

The two input pins share a boss.

A high-voltage coil is formed by packaging a coil in a shell, wherein the shell is provided with an output port, and an output pin of the coil extends into the output port and is connected with a lead wire inserted in the output port; the coil is the coil.

The output port is positioned on the back of the coil framework, and the output pins are bent outwards and extend into the output port;

the high-voltage wire package is high in damage frequency in use, researches show that the damage is caused by the fact that an enameled wire wound on a coil framework is broken, and further show that an input pin is bent outwards to strain the enameled wire, and the enameled wire is thin and easy to break for a long time. Based on this, when the enameled wire is wound, the connection end of the enameled wire and the output pin is wound to the outer side of the coil framework and connected with the output pin, so that the input pin is bent outwards, and the enameled wire cannot be tensioned. The frequency of high voltage coil damage is greatly reduced.

The end face of the coil framework is provided with a salient point; the connecting end of the enameled wire and the output pin bypasses the salient point from the lower end.

The front surface of the coil framework is provided with a groove communicated with the end surface of the coil framework; and the connecting end of the enameled wire and the output pin passes through the groove to be led out.

An igniter is assembled by a high-voltage coil, a transformer and a control panel; the high-voltage coil is the high-voltage coil.

The invention has the advantages of reasonable design, ingenious conception and the following beneficial effects:

1) researches find that the input pin is close to the enameled wire, which causes the coil to have high breakdown frequency, and on the basis, the structure of the coil framework is improved, so that the breakdown frequency of the coil is greatly reduced.

2) Researches find that the output pin bends and tensions the enameled wire to cause damage of the high-voltage wire package, and on the basis, the winding mode of the enameled wire is improved, so that the frequency of the damage of the high-voltage wire package is greatly reduced.
