Abstract

The utility model relates to a solid fuel chafing dish, which is composed of a base, a chafing dish supporter, a barrel, a barrel lifting device, a combustion chamber, an air door ring and a combustion chamber fixing bracket, wherein, the barrel lifting device is composed of a nut, a screw rod and a tray. The utility model is characterized in that the combustion chamber is an open container whose sides and bottom are provided with uniformly distributed pores; the air door ring whose periphery is provided with uniformly distributed pores is fixedly connected with the lower part of the combustion chamber; the upper end of the barrel is slide fit with the air door ring. The utility model has the advantages that the fuel can burn completely; the power of burning can be adjusted easily; no smoke and smell are produced; the use is convenient and safe.

Description

Solid fuel chafing dish

The utility model relates to a kind of Solid fuel chafing dish, particularly is the special-purpose chafing dish of solid fuel of Main Ingredients and Appearance with ethanol.

At present, the solid fuel that with ethanol is Main Ingredients and Appearance does not have corresponding supporting special-purpose chafing dish, normally fuel is placed on the burning of giving free rein in the can, the firepower size can not be regulated, fuel can not get abundant burning, and the thermal efficiency is low, and smoke pollution and smell are arranged, maximum temperature has only about 500 ℃, and discomfort is fit to do chafing dish and uses.

The purpose of this utility model is to provide the ethanol solid fuel that a kind of fuel can rationally fully burn, the firepower size is convenient to regulate special-purpose chafing dish.

Technical characterictic of the present utility model is, barrel lowering or hoisting gear, combustion chamber, air door circle, combustion chamber fixed support that the composition of Solid fuel chafing dish comprises base, pot supporter, barrel, is made up of nut, screw rod, pallet, the combustion chamber is an open-top receptacle, the even distributed pores in its side and bottom, the air door circle is fixedly connected on the below, combustion chamber, its periphery is distributed pores evenly, and the barrel upper end is slidingly matched with the air door circle.

With reference to the accompanying drawings and in conjunction with the embodiments the utility model is described in detail.

Fig. 1 is the utility model user mode schematic diagram.

Fig. 2 is Figure 1A-A cut-away view.

Fig. 3 is the utility model user mode schematic diagram.

As depicted in figs. 1 and 2, the composition of the utility model Solid fuel chafing dish comprises that base 10, pot supporter 6, barrel 5, barrel lowering or hoisting gear, combustion chamber 1, air door circle 2, combustion chamber fixed support 3, the combustion chamber 1 be made up of nut 8, screw rod 9, pallet 7 are an open-top receptacle, the equal distributed

pores

13,12 in its side and bottom, air door circle 2 is fixedly connected on 1 below, combustion chamber, its periphery is distributed pores 11 evenly, and barrel 5 upper ends and air door circle 2 can be slidingly matched.Be fixed on the base 10 pot supporter 6 circumference in equal parts, the fixedly connected combustion chamber 1 of combustion chamber fixed support 3 one ends, the other end is fixed on the pot supporter 6 by screw 4, thereby combustion chamber 1 is fixed on the certain altitude of pot supporter 6.Barrel 5 places on the pallet 7, and pallet 7 places on the base 10, and screw rod 9 is contained in pallet 7 bottoms, be connected with nut 8 spirals that are fixed on the base center, with hand Rotary tray 7, can change the relative position of screw rod 9 and nut 8, thereby make pallet 7 ask barrel 5 to rise or descend.

As shown in Figure 3, pot 14 places the utility model pot supporter 6 upper ends, and all the other labels illustrate with Fig. 2 among the figure.

Using method of the present utility model is described in conjunction with Fig. 2 and Fig. 3.

1, rotary-tray 7 makes it to descend, and barrel 5 is taken out, and barrel is put back on the pallet behind the threading ethanol solid fuel, with match or lighter igniting again;

2, after the igniting, rotary-tray again, make it to rise, contact with air door circle 2 up to barrel 5 upper ends, the two is slidingly matched, and 1 bottom pore 12 enters the combustion chamber to the gas of burning through the combustion chamber, and oxygen enters the combustion chamber by the side pore 13 of air door circle 2 peripheral pores 11 and combustion chamber, make the gas of burning carry out second-time burning, reach clean-burning purpose;

3, regulating the firepower size is to realize by the switching of controlling air door circle 2 peripheral pores 11, need firepower big, just air door circle pore 11 bottoms are transferred in the barrel upper end, air door circle pore is all opened, need reduce firepower, then the barrel upper end is progressively raised, make its partial occlusion air door circle pore 11, until all blocking air door circle pore;

When 4, flame-out, the pallet rotation is descended, barrel breaks away from and the contacting of air door circle, and covers the barrel mouth with cover plate (meaning not shown in the figures), and the interior fuel of the barrel oxygen that breaks extinguishes.

Upwards enter the combustion chamber for the gas that makes the barrel internal combustion is concentrated, the further feature of the utility model is that the center of going to the bottom of combustion chamber 1 is the shape that upwards arches upward.

The utility model is safe and convenient to use, and fuel can be fully burned, and the firepower size can free adjustment, and ignition temperature reaches more than 700 ℃, and 100 gram ethanol solid fuels can continuous burnings about 1 hour, and smokeless, nontoxic, odorlessness suitablely use as chafing dish.

Claims

1, a kind of Solid fuel chafing dish, it is characterized in that forming the barrel lowering or hoisting gear, combustion chamber, air door circle, the combustion chamber fixed support that comprise base, pot supporter, barrel, form by nut, screw rod, pallet, the combustion chamber is an open-top receptacle, the even distributed pores in its side and bottom, the air door circle is fixedly connected on the below, combustion chamber, its periphery is distributed pores evenly, and the barrel upper end is slidingly matched with the air door circle.

2, Solid fuel chafing dish according to claim 1 is characterized in that the center of going to the bottom of combustion chamber is the shape that upwards arches upward.
