Problems solved by technology
[0002] The flash point is the lowest temperature at which the test flame causes the vapor of the sample to ignite and spread the flame to the surface of the liquid under the specified test conditions. The existing flash point tester needs to place the sample on a heating plate and ignite it through the heater The sample is heated from the bottom of the heating plate, and the fire source is driven by the sliding sweeping device to sweep over the sample to heat the sample, so as to complete the test purpose, and the ignition device of the existing flash point tester adopts gas ignition , it is difficult to control the flame and temperature, which will affect the test results. In addition, the ignition head on the commonly used ignition device is a 3-4mm sphere. This method will lead to uneven ignition, which will cause errors in the detected flash point value. Inaccurate

The invention discloses an ignition device of a flash point tester and a control module of the ignition device. The ignition device comprises an ignition head, wherein an ignition wire is arranged at the front end of the ignition head; the ignition head is fixed on a fixing sleeve; a ceramic tube is arranged at the position where the ignition head is connected with the fixing sleeve; an ignition wire rear sleeve is fixed at the other end, away from the ceramic tube, of the fixing sleeve; and the control module is electrically connected with the ignition device and is used for controlling the ignition device to ignite. According to the ignition device, an ignition wire structure and an electric ignition mode are adopted, no open fire or gas source exists in the ignition process, the flame size does not need to be adjusted, the ignition device is safer, and the test accuracy is higher.
