Technical problem of the present utility model is achieved through the following technical solutions:

A kind of energy-saving stove burner, comprise the cast iron circle, this cast iron circle is provided with fuel gas inlet and the outlet passageway that communicates with its inner chamber, be provided with the adjustable height mixture cylinder of supply air mixture at the fuel gas inlet place, discus is installed and around the heat collector panel of discus circle distribution at the top of mixture cylinder, has bocca on the discus, simultaneously on the cast iron circle that is positioned at discus one side, the igniter of lighting bocca is installed, it is characterized in that described mixture cylinder is provided with support, the heat collector panel circle distribution is on this support; Described outlet passageway is the venthole that is distributed in cast iron circle periphery.

The contact-making surface in the described cast iron circle top and the bottom of a pan is a ramp structure.

Described venthole is 12, is distributed on the peripheral position of central angle alpha=90, cast iron circle top °.

Described discus cylindrical is step, and its end face is the indent spherical structure.

Described bocca is 8, is respectively 1 vertical bocca being located at the center and is 7 inclination boccas of center of circle circumference uniform distribution with the center.

Described inclination bocca is for pressing counterclockwise to tilt in the same way.

Be provided with ceramic core in the described bocca, this ceramic core is provided with 8 pinkeye, is respectively 1 pinkeye being located at the center and is 7 pinkeye of center of circle circumference uniform distribution with the center.

Compared with prior art, the utility model is that the burner to energy-saving stove improves, and has additional support to support heat collector panel on mixture cylinder, prevents that the heat collector panel after the weathering is broken under the deadweight effect; Improved the outlet passageway structure, will be positioned at the deep-slotted chip breaker that cast iron circle top peripheral position is 90 ° and replace,, prevented to ftracture in the use of cast iron circle, also played the effect that reduces the heat collector panel weathering speed to reduce material stress with the uniform venthole of arc; The discus cylindrical is designed to the step that easier finger is taken, and the discus bocca is designed to more ignitable incline structure, simultaneously other structure of burner is also carried out corresponding improvement to improve the thermal efficiency, design is ingenious, loading and unloading are easy, burning area big so the structure after improving has, the advantage of longer service life.

The specific embodiment

To elaborate again to the utility model embodiment by above-mentioned accompanying drawing below.

As Fig. 1～shown in Figure 8, concave spherical surface, 15-circular hole, 16-convex shoulder, 17-bocca in 1-cast iron circle, 2-combustion chamber, 3-ceramic core, 4-inlet chamber, 5-ramp structure, 6-support, 7-discus, 8-bolt, 9-mixture cylinder, 10-venthole, 11-igniter, 12-fuel gas inlet, 13-pinkeye, the 14-.

A kind of energy-saving stove burner, the cast iron circle 1 that comprises cast molding, cast iron circle such as Fig. 3, shown in Figure 4, has inner-cavity structure, this inner chamber is made of the annular inlet chamber 4 that combustion chamber 2 in the middle part of the cast iron circle and cast iron circle top communicate with combustion chamber, cast iron circle top is provided with the outlet passageway that communicates with annular inlet chamber 4, this outlet passageway is made of 12 ventholes 10 that are distributed on cast iron circle 1 top central angle alpha=90 ° peripheral position, compare with the outgassing groove of original structure, when this venthole is ventilated except can be used as burner, its even distributed architecture can effectively reduce cast iron circle 1 stress, makes the cast iron circle not easy to crack.Contact-making surface with the cast iron circle 1 and the bottom of a pan is designed to ramp structure 5 simultaneously, and this structure in use can make and form air blanketing in the cast iron circle, reduces heat exhaustion, improves the thermal efficiency.
