Abstract
A pulse-free electronic igniter comprises a lead wire, a fixing sleeve and a silicon nitride ignition rod. One end of the silicon nitride ignition rod is an electrode end, the other end of the silicon nitride ignition rod is a heating end, the electrode end is nested in a fixing sleeve, the heating end exposes out of the fixing sleeve, one end of the lead wire is arranged in the fixing sleeve to be connected with the electrode end, and the other end of the lead wire is connected with a power supply. The problem that when a fire disaster is caused by improper handling during open fire usage or an electronic pulse igniter is used, electronic interference is easily produced, and the measurement accuracy of other instruments is influenced is solved.
Description
Technical field
The utility model relates to a kind of igniter, relates in particular to a kind of no pulse ignition, the ignition function of system while being applied to test.
Background technology
When laboratory is analyzed and tested Related product, carry out combustion ignition to combustion gas etc.Conventional method is to use naked light, as: match, lighter or electronic impulse ignition apparatus igniting, but the problem existing is: while using naked light, operates or deals with improperly and can cause fire; And while using electronic impulse ignition apparatus, easily produce electronic interferences, and affecting the certainty of measurement of other instruments, service life is short; Ignition installation is separated with tester, easily loses, and uses inconvenient.
Utility model content
While using naked light in order solving, to deal with improperly when can cause fire or using electronic impulse ignition apparatus, easily to produce electronic interferences, affect the problem of the certainty of measurement of other instruments, the utility model provides a kind of no pulse ignition.
No pulse ignition, comprises wire, fixed cover and silicon nitride fire rod; Described silicon nitride fire rod one end is electrode tip, and the other end is heating end, and described electrode tip is nested in fixed cover, and heating end exposes outside fixed cover, and described wire one end is placed in fixed cover and is connected with electrode tip, and its other end is connected with power supply.
Described fixed cover is provided with the circular hole of two row's symmetries.
The beneficial effects of the utility model are: no pulse ignition, substituted traditional sparking mode, and without flame, handling safety is reliable, and heating power is controlled, easy to use, noiseless to the certainty of measurement of other instruments; Thermal diffusivity is good, simple in structure, cost is low, due to after silicon nitride material itself heating not can with air reaction, so oxidation resistance is strong, greatly extended service life, energy-conserving and environment-protective.
Accompanying drawing explanation
The utility model has accompanying drawing 1 width.
Fig. 1 is the structural representation of no pulse ignition.
Sequence number explanation in figure: 1, wire, 2, fixed cover, 3, silicon nitride fire rod.
The specific embodiment
Below in conjunction with specific embodiment, the utility model is further illustrated, no pulse ignition, comprising: wire 1, fixed cover 2 and silicon nitride fire rod 3; Described silicon nitride fire rod 3 one end are electrode tip, and the other end is heating end, and described electrode tip is nested in fixed cover 2, and heating end exposes outside fixed cover 2, and described wire 1 one end is placed in fixed cover 2 and is connected with electrode tip, and its other end is connected with power supply.
During use, wire 1 switches on power, and silicon nitride fire rod 3 produces heat rubescent, while reaching the ignition temperature of fuel, in order to fire fuel.
Claims (2)
1. no pulse ignition, is characterized in that: comprise wire (1), fixed cover (2) and silicon nitride fire rod (3); Described silicon nitride fire rod (3) one end is electrode tip, the other end is heating end, and described electrode tip is nested in fixed cover (2), and heating end exposes outside fixed cover (2), described wire (1) one end is placed in fixed cover (2) and is connected with electrode tip, and its other end is connected with power supply.
2. no pulse ignition according to claim 1, is characterized in that: described fixed cover (2) is provided with the circular hole of two row's symmetries.
