A fire cover for a gas stove

Abstract

The invention relates to a fire cover for a gas stove, which includes a fire cover body, the fire cover body has a gas mixing chamber, and the upper surface of the annular top wall of the fire cover body is from the inner ring wall to the outer ring wall toward the fire cover The center of the body extends radially outwards to form a fire transfer chamber, which is characterized in that: it also includes a gas hole and an adjustment ring opened on the inner wall of the fire transfer chamber, which communicates with the gas mixing chamber, and the outer wall of the adjustment ring has At least one gas outlet, each gas outlet is connected with the gas outlet of the corresponding gas ring, and the adjustment ring can move in the circumferential direction relative to the gas ring under the action of external force, thereby changing the gas outlet of the gas ring relative to the gas outlet of the adjustment ring. position, and then change the cross-sectional area of ​​the effective air flow channel of the air outlet. Compared with the prior art, the present invention has the advantage of being able to adapt to different air source pressures and avoiding the phenomenon of misfire due to low air source pressure.

Description

Technical field [0001] The present invention relates to a burner for domestic appliances, in particular, it relates to fire cap for a gas cooker. Background technique [0002] Currently, the marketed conventional burner fire cap mostly through a slot milling, i.e., milling the top of the fire cap body has a through groove fire, such a burner fire cap for a fire cap body is in the ignition slot disconnect, which can easily cause thermal deformation of the cover body, thus affecting the priming effect. If a patent number 201220464214.0 (Publication No. is CN202813375U) Chinese invention patent "means having a gas burner and a fire transfer flame protection function" which discloses similar fire transmission structure, which is provided with a plurality of flame in the outer ring outer ring ring flame hole, and a hole in the outer ring also has an outer ring pass flame ignition device, the ignition device is transmitted by the outer ring mounted on the outer sidewall flame circle bo...

AI Technical Summary

Problems solved by technology

Supplement air to the fire transmission channel through the secondary air supplementary hole, thereby promoting the efficient combustion of the fire transmission flame in the fire transmission channel, thereby increasing the fire transmission speed, although the fire transmission channel solves the air problem of the hidden fire transmission channel, and The problem of gas in the hidden fire transmission channel has not been solved. Due to the different gas source pressures in different regions, if the pressure is too low, it is easy to cause no gas in the hidden fire transmission channel, and if the pressure is too fast, it is easy to cause the hidden fire transmission channel to be damaged. If the internal gas speed is fast and there is no air, it will cause the phenomenon of misfire
