Abstract

The utility model relates to an improved valve body ignition bracket of a household fuel gas domestic appliance igniter. The utility model is characterized in that an ignition needle is arranged outside the outlet end of the valve body ignition bracket; the ignition spark negative pole is of the outer lead-out point of the outlet of the valve body ignition bracket to make the ignition spark to be arranged on the main passage of the valve body ignition bracket. The ignition bracket has the advantages of the high firing rate and large applicable scope. The utility model is suitable for liquefied petroleum gas, natural gas as well as artificial gas in both the piezoelectric ignition way and the pulse ignition way.

Description

A kind of household gas utensils valve body point fire support

The utility model relates to the improvement of household gas utensils fire maker valve body, especially to the improvement of kitchen range valve body point fire support.

As everyone knows, household gas utensils all are to adopt piezo-electric ignition and pulsed electron igniting dual mode basically, and normal domestic use gas kitchen ranges great majority adopt by lighting the rifle of igniting, and then light the way of cooker burner.Why adopt this mode and do not adopt the then mode of igniting, its reason to be, the combustion gas ratio is big in the pyrophoric flame, is easy to light, the rate of catching fire height, and cost is low, especially the piezoelectric ceramics sparking mode.At present, adopt the some fire support of this sparking mode on the market, all be to adopt from the main passage of igniting to isolate a part of combustion gas from the side with Air mixing gas is lighted a fire, the igniting gas-air of rifle main channel again ignites behind the gaseous mixture by having lighted.Yet, there is following defective in this way by the main channel gas that ignites again behind the gaseous mixture of having lighted the next door: because the gaseous mixture of drawing from the side, negligible amounts, periphery contact more air is when combustion gas composition or pressure change, when especially using combustion gas composition such as natural gas, artificial gas or pressure to change big source of the gas, air capacity is excessive, is difficult to light, and makes that the igniting of the valve body rate of catching fire is low, even the non-ignitable phenomenon of appearance point, seriously influenced the normal use of kitchen range.

The purpose of this utility model is by improving valve body igniting supporting structure, to change the position of pilot spark, rate height, wide accommodation so that the igniting of valve body is caught fire.

The utility model is achieved in that a kind of household gas utensils valve body point fire support, form by the support of igniting (1), igniting pin (2), ignition burner (3), igniting pin (2) places outside the port of export (6) of the support of igniting (1), its pilot spark negative pole point is leading point (7) outside the outlet (6) of support (1) of igniting, and pilot spark places the port of export (8) on the main channel of igniting (4).Like this, the air that the combustion gas of ignition burner (3) ejection and injection advance forms the gaseous mixture of igniting, igniting pin (2) forms pilot spark with the outer end (7) of support (1) of igniting at the main channel outer vent (8) of igniting, and is easy to the gaseous mixture of igniting is lighted, thereby lights cooker burner.

Advantage of the present utility model is that cost is low, and the rate height that catches fire of lighting a fire is applied widely.

Below provide embodiment, the utility model is further described.

Fig. 1 is a forward schematic diagram of the present utility model.

Fig. 2 is a forward cross-sectional schematic of the present utility model.

Fig. 3 is a dextrad cross-sectional schematic of the present utility model.

A kind of household gas utensils valve body point fire support, form by the support of igniting (1), igniting pin (2), ignition burner (3), igniting pin (2) places outside the port of export (6) of the support of igniting (1), its pilot spark negative pole point is leading point (7) outside the port of export (6) of support (1) of igniting, and pilot spark places the port of export (8) on the main channel of igniting (4).Like this, the air that the combustion gas of ignition burner (3) ejection and injection advance forms the gaseous mixture of igniting, igniting pin (2) is gone up at the main channel outer vent (8) of igniting with the outer end (7) of support (1) of igniting and is formed pilot spark, is easy to the gaseous mixture of igniting is lighted, thereby lights cooker burner.

Claims

A kind of household gas utensils valve body point fire support, form by the support of igniting (1), igniting pin (2), ignition burner (3), the pin (2) that it is characterized in that lighting a fire places outside the port of export (6) of the support of igniting (1), its pilot spark negative pole point is positioned at leading point (7) outside the outlet (6) of the support of igniting (1), and pilot spark places the port of export (8) on the main channel of igniting (4).
