Abstract
The utility model relates to the field of combustion stoves and discloses a fixing structure of an ignition needle, which comprises a stove head and an ignition needle body, wherein the stove head is upwards provided with a section of sleeve, the middle upper part of the ignition needle body is provided with an annular boss, the ignition needle body is inserted into the sleeve from top to bottom through an elastic sleeve, and the bottom end face of the annular boss is attached to the top end of the sleeve. The device can prevent the ceramic ignition needle from being broken after being impacted, and can solve the problem of breaking of the existing copper sleeve ignition needle structure caused by stress under the action of high temperature during working.
Description
Technical Field
The utility model relates to the field of combustion stoves, in particular to a fixing structure of an ignition needle.
Background
The prior gas stoves of various brands are provided with two modes for fixing the ignition needle, one is that the ceramic ignition needle is fixed by a clamp spring, and the other is that the copper sleeve ignition needle is fixed by a nut/screw. Mode one: the ceramic ignition needle is an integral ceramic, and is easy to break by external force in the cleaning process after transportation and use due to the inherent characteristics of the ceramic, and the like, so that the ignition failure of the gas stove is caused. Mode two: the copper sleeve ignition needle is adopted, the ceramic body is protected by the copper sleeve, the problem that the ceramic body is easy to break off by external force in the cleaning process after transportation and use is solved, but the copper sleeve needs to be of enough thickness (more than 0.6 mm) to play a role in protection, and the cost is increased by about 1 yuan; importantly, the riveting/connecting and fixing of the copper sleeve and the ceramic body generate stress to a certain extent, and the copper sleeve is easy to break under the action of high temperature during working, so that the brand of the gas cooker head does not adopt the structure.
Disclosure of Invention
The utility model aims to provide a fixing structure of an ignition needle, which can not only prevent the ceramic ignition needle from being broken after being impacted, but also solve the problem of breaking stress generated by the existing copper sleeve ignition needle structure under the action of high temperature during working.
In order to achieve the above purpose, the technical solution adopted by the utility model is as follows:
the utility model provides a fixed knot of ignition needle constructs, includes furnace end and ignition needle body, the furnace end upwards is provided with one section sleeve, and the well upper portion of ignition needle body is provided with annular boss, the ignition needle body is pegged graft in the sleeve through elastic sleeve top-down, and annular boss's bottom end surface is laminated with telescopic top mutually.
Preferably, a section of groove is arranged below the annular boss, and the elastic sleeve is arranged in the groove.
Preferably, the upper end and the lower end of the elastic sleeve are annular openings, the middle section of the elastic sleeve is of an arc structure gradually protruding from the upper end and the lower end of the elastic sleeve to the middle, and a plurality of evenly distributed vertical cuts are formed in the middle section along the circumferential direction.
Preferably, the ignition needle is a ceramic ignition needle.
Preferably, the elastic sleeve is made of high-temperature resistant spring material.
Compared with the prior art, the utility model has the beneficial effects that:
the utility model discloses a fixing structure of an ignition needle, wherein a protective rigid structure is arranged on a furnace end, so that the ceramic ignition needle and the rigid protective structure of the furnace end are in clearance fit, and an elastic sleeve is adopted in the middle of the clearance to realize fixation, thereby realizing impact protection, avoiding stress under the action of high temperature and greatly reducing the fault pain point of the ignition needle; meanwhile, the ignition needle fixing structure is not limited to an integral structure with the burner, and can be used for products such as gas cookers, integrated cookers and the like.

In the figure, a 1-ignition needle body; 2-an elastic sleeve; 3-burner; 4-an annular boss; 5-grooves; 6-sleeve; 201-upper end of elastic sleeve; 202-the lower end of the elastic sleeve; 203-vertical cuts.
Detailed Description
The ignition needle fixing structure comprises a furnace end 3 and an ignition needle body 1, wherein the furnace end 3 is provided with a section of sleeve 6 upwards, the ignition needle is a ceramic ignition needle, the middle upper part of the ignition needle body 1 is provided with an annular boss 4, the ignition needle body 1 is spliced in the sleeve 6 from top to bottom through an elastic sleeve 2, and the bottom end surface of the annular boss 4 is attached to the top end of the sleeve 6. A section of groove 5 is arranged below the annular boss 4, the elastic sleeve 2 is arranged in the groove 5, and the elastic sleeve 2 is made of high-temperature-resistant spring materials. The upper and lower ends of the elastic sleeve 2 are annular openings, the middle section of the elastic sleeve 2 is provided with an arc structure gradually protruding from the upper and lower ends of the elastic sleeve 2 to the middle, and a plurality of evenly distributed vertical cuts 203 are formed in the middle section along the circumferential direction.
The elastic sleeve 2 is preassembled on the groove 5 of the ceramic ignition needle, and then the connecting wire of the ignition needle of the preassembly component penetrates through the structural hole of the furnace end 3, and the preassembly component is pressed down, so that the annular boss 4 of the ceramic ignition needle is attached to the top end of the sleeve 6. The ceramic ignition needle is assembled and fixed with the furnace end 3 in a clearance way through the elastic sleeve 2, so that the impact protection is realized, and the stress under the action of high temperature is avoided.
It should be understood that the above description is not intended to limit the utility model to the particular embodiments disclosed, but to limit the utility model to the particular embodiments disclosed, and that the utility model is not limited to the particular embodiments disclosed, but is intended to cover modifications, adaptations, additions and alternatives falling within the spirit and scope of the utility model.
