Description

Novel firewood stove

Technical Field

The utility model relates to a firewood stove technical field, concretely relates to novel firewood stove.

Background

The firewood stove is a common burning appliance in daily life, is used more when camping outdoors, mainly comprises a stove body and a firewood adding opening at the bottom of the stove body, cookers such as a kettle and a pot can be placed at the upper end of the stove body for cooking food, and an upper cover is also arranged at the upper end of some stoves for covering the stove fire to prevent the stove fire from being sprayed all around. Traditional firewood stove is easy because the burning does not fully produce a large amount of black cigarettes, need carry out the oxygenation through electric blower when furnace inside oxygen is not enough moreover, and combustion efficiency is not high, to sum up, the utility model discloses improved traditional firewood stove, designed a novel firewood stove.

SUMMERY OF THE UTILITY MODEL

The utility model aims at providing a novel firewood stove, structural design is reasonable, can improve combustion efficiency, reduces the black cigarette of firewood burning, excellent in use effect, and the practicality is strong.

In order to achieve the above purpose, the present invention is realized by the following technical solution: a novel firewood stove comprises a base, a convex-bottom combustion chamber, a double-layer hearth, a fire gathering ring, a support and a speed-regulating fan. Be provided with the air inlet around the firewood stove base bottom, protruding end combustion chamber bottom central part is protruding bottom part, be flat bottom part around the protruding bottom part, and the protruding bottom part and the flat bottom part of combustion chamber all are provided with the air vent, protruding end combustion chamber center is provided with foraminiferous ventilation honeycomb duct, protruding end combustion chamber top is double-deck furnace, the double-deck furnace top is provided with gathers the fire circle, it is provided with the support of placing the iron pan to gather on the fire circle, the speed governing fan links to each other with the blast pipe, the blast pipe is connected to in the honeycomb duct.

Preferably, the center of the convex-bottom combustion chamber is provided with a flow guide pipe with a vent hole.

Preferably, an air inlet hole is arranged around the bottom of the base.

Preferably, wood gas inlet holes are arranged around the upper end of the inner wall of the double-layer hearth.

Preferably, the diameter of the air supply pipe is smaller than that of the guide pipe.

Preferably, the fire gathering ring plays a role in gathering flames, and the central draft tube is matched with the fire gathering ring for use, so that the blast aeration can play a role in fully combusting in the flames.

The utility model has the advantages that: the utility model discloses only to firewood flame oxygenation burning, reduce the black cigarette of firewood burning, improve the flame temperature. Because the outlet of the ventilation guide pipe at the center of the furnace bottom is arranged at the middle upper position of the fuel, the air blast effect can not accelerate the combustion of the firewood and can not reduce the combustion time of the firewood.

Drawings

The present invention will be described in detail with reference to the accompanying drawings and specific embodiments;

fig. 1 is a schematic structural view of the present invention;

fig. 2 is an enlarged schematic view of the bottom of the combustion chamber of the present invention.

Detailed Description

In order to make the technical means, creation features, achievement purposes and functions of the present invention easy to understand, the present invention is further described below with reference to the following embodiments.

Referring to fig. 1-2, the following technical solutions are adopted in the present embodiment: the utility model provides a novel firewood stove, the on-line screen storage device comprises a base 1, protruding end combustion chamber 2, double-deck furnace 3, gather fire circle 4, support 5 and direct current speed governing fan 6, be provided with protruding end combustion chamber 2 on the base 1, 2 bottoms of protruding end combustion chamber lean on central department to divide 7 for protruding bottom, protruding bottom divides 7 to be flat 10 on every side, and the protruding bottom of combustion chamber divides 7 and flat 10 part all to be provided with the air vent, 2 bottom centers of protruding end combustion chamber are protruding and to be provided with

honeycomb duct

8, 2 tops of protruding end combustion chamber are double-deck furnace 3, 3 tops of double-deck furnace are provided with and gather fire circle 4, it is provided with the support 5 of placing the iron pan on fire circle 4 to gather, speed governing fan 6 links to each other with blast pipe 9, blast pipe 9 is connected to in.

It is worth noting that the center of the convex bottom combustion chamber 2 is provided with a draft tube 8 with a vent hole.

It is worth noting that air inlet holes are arranged around the bottom of the base 1.

It is worth noting that wood gas inlet holes are arranged around the upper end of the inner wall of the double-layer hearth 3.

In addition, the diameter of the blast pipe 9 is smaller than that of the draft pipe 8.

The working principle of the specific embodiment is as follows: when the novel firewood stove is used, firewood is ignited from the upper part and burns from the top to the bottom, the lower layer firewood is burnt by the upper layer at high temperature and is subjected to destructive distillation to generate wood gas, and because the density of the wood gas is less than the density of air, part of the wood gas coming out of small holes around the stove bottom flows upwards along the space between the inner wall of the base and the outer wall of the combustion chamber and the space between the interlayer of the upper double-layer hearth in a convection manner, and flows into the stove chamber from the holes on the inner wall of the double.

The wood gas flowing out from the convex bottom is mixed with air due to the flow guiding effect of the convex bottom inclined plane, the central flow guide pipe and the speed-adjusting fan, and is fully combusted in the flame formed by the fire gathering ring and the hearth, so that the formation of black smoke is reduced, the temperature of the flame for heating the pot body is also increased, and even when electric air blowing is not performed, the air which naturally convects to rise is introduced into the hearth for oxygenation due to the fact that the pipe diameter of the electric air blowing pipe is smaller than that of the central flow guide pipe.

The firewood stove of the specific embodiment has reasonable structural design, only carries out oxygen-increasing combustion on the firewood, reduces black smoke generated by the combustion of the firewood and improves the flame temperature. Because the outlet of the ventilation guide pipe at the center of the furnace bottom is arranged at the middle upper position of the fuel, the air blast effect can not accelerate the combustion of the firewood and can not reduce the combustion time of the firewood.

The basic principles and the main features of the invention and the advantages of the invention have been shown and described above. It will be understood by those skilled in the art that the present invention is not limited to the above embodiments, and that the foregoing embodiments and descriptions are provided only to illustrate the principles of the present invention without departing from the spirit and scope of the present invention. The scope of the invention is defined by the appended claims and equivalents thereof.
