The air inlet 530 is an air inlet portal of the furnace 100, the flow area of the air inlet 530 is closely related to the fire in the furnace 100, and the larger the flow area of the air inlet 530 is, the more oxygen flows into the furnace 100 in a unit time.

Further, in order to adjust the flow area of the air inlet 530, the furnace chamber 100 is connected with an adjusting member 531 at the air inlet 530. Specifically, the air inlet 530 is connected with a first web, a plurality of first through holes are annularly arranged on the first web, the adjusting piece 531 may be a second web, a plurality of second through holes are annularly arranged on the second web, the shape and the size of the second web are similar to those of the first web, so that the second web can be overlapped with the first web, and all the first through holes and all the second through holes after overlapping are aligned one by one respectively.

It is to be understood that the structure of the air inlet 530 and the structure of the adjusting member 531 are not limited in the present utility model, and no matter what structure the two structures are, the two structures are within the protection scope of the present utility model as long as the two structures can adjust the flow area of the air inlet 530 after being matched.

In order to facilitate the cleaning of ashes generated after combustion, the furnace 100 is provided with a push-pull ash bucket 120 below the switch door 500, the ash bucket 120 and the switch door 500 jointly cover the open surface of the furnace 100, and the ash bucket 120 is used for loading ashes. When ash has accumulated to some extent, the user may pull the hopper 120 from the inside out and dump the ash therein.

As shown in fig. 2 and 5, the furnace 100 is provided with an air outlet 130 on a vertical surface opposite to the switch door 500, the air outlet 130 is connected with an air outlet pipe 600, the air outlet 130 is connected with a filter screen 610 to isolate slightly larger ash in the furnace 100, the end of the air outlet pipe 600 is connected with the heating pipe 300, and the end of the heating pipe 300 is connected with the smoke pipe 400. Specifically, the heat generating tube 300 is provided with a plurality of turning positions along the length direction thereof, so that the heat generating tube does not occupy a large number of space positions under the condition of keeping a long flow passage, and heat is better emitted into indoor air; the heating tube 300 is provided with a second observation window 310, the second observation window 310 may be made of a high temperature resistant glass material, so that a user can observe the fire in the heating tube 300 from outside to inside, and the user can comprehensively judge whether the biomass timber is absent in the combustion chamber 710 through the first observation window 520 and the second observation window 310. The length of the smoke tube 400 depends on the indoor space, and the exhaust port of the smoke tube 400 needs to be extended to the outdoor so as to avoid potential safety hazard.

Meanwhile, a blanking port 140 is formed in the top surface of the furnace 100, and the blanking port 140 is used for communicating with the bin 200. The bin 200 is used for storing biomass timber, the bin 200 is provided with a feed inlet 210 and a discharge outlet 220, the feed inlet 210 of the bin 200 is positioned on the top surface of the bin 200, the top cover 211 is adopted for covering the feed inlet, and the discharge outlet 220 is positioned on the bottom surface of the bin 200. The bottom of the bin 200 is funnel-shaped, because the flow area of the outlet 220 is smaller than the flow area of the inlet 210.

A funnel 700 is further disposed between the furnace 100 and the bin 200, the funnel 700 is provided with a combustion chamber 710 that can pass through the blanking port 140, the combustion chamber 710 is specifically a grate, and the size of the grate is smaller than that of the biomass timber, so as to limit the biomass timber in the combustion chamber 710. The funnel 700 is welded to the top surface of the furnace 100, and the combustion chamber 710 of the funnel 700 passes through the blanking port 140 and is located in the furnace 100, where the combustion chamber 710 is directly connected to the blanking port 140. The bin 200 is connected to the funnel 700, so that the discharge port 220 is in linear communication with the combustion chamber 710, and biomass timber in the bin 200 can sequentially pass through the discharge port 220 and the blanking port 140 from top to bottom under the action of gravity and finally is accumulated in the combustion chamber 710.

It will be appreciated that, since the bottom of the bin 200 is funnel-shaped, the funnel 700 may be omitted, i.e. the bin 200 may be directly connected to the furnace 100, and the combustion chamber 710 may also be directly connected to the blanking port 140 of the furnace 100, which is not limited to the above embodiment.

As shown in fig. 3 and 5, in order to avoid the occurrence of flashback, the position of the combustion chamber 710 is not lower than the position of the air inlet 530, and since the air inlet 530 and the air outlet 130 of the furnace 100 are forward, when the air flow is guided from the air inlet 530 to the air outlet 130, the bottom of the combustion chamber 710 becomes an oxygen-enriched area, and the biomass wood is fully combusted in this area, so that the flame direction is generally downward to block the occurrence of flashback.

Further, in order to stabilize the airflow direction in the furnace 100 and reduce the occurrence of turbulence, the flow area of the air inlet 530 is smaller than the flow area of the air outlet 130, and at this time, the air inlet pressure of the furnace 100 is greater than the air outlet pressure of the furnace 100, so that the airflow can stably pass through the bottom of the combustion chamber 710, so as to reduce the fire at the top of the combustion chamber 710. Moreover, when the feed port 210 of the bin 200 is opened, since the bin 200 is communicated with the furnace 100 and the flow area of the air inlet 530 is smaller than the flow area of the air outlet 130, a part of air enters the furnace 100 from the bin 200 to limit the flow direction of the air in the bin 200, so as to further inhibit the occurrence of flashback.

When the combustion heat preservation device is used, a user firstly inputs a large amount of biomass timber from the feed inlet 210 of the storage bin 200, and under the action of gravity, the biomass timber sequentially passes through the discharge outlet 220 and the blanking outlet 140 from top to bottom and finally is accumulated in the combustion chamber 710. Subsequently, the user opens the switch door 500, ignites the biomass timber in the combustion chamber 710 by using an igniter, closes the switch door 500 after ignition, and oxygen enters the hearth 100 from the air inlet 530, so that the biomass timber forms fine ashes after being fully combusted, and the ashes can fall into the ash bucket 120 below under the driving of the airflow, and at the moment, the space vacated in the combustion chamber 710 is automatically filled by the biomass timber above, so as to realize the unpowered pushing effect. On the other hand, the hot air generated by the combustion enters the heating tube 300 from the air outlet 130, so that the heating tube 300 can generate heat radiation and heat convection outwards to raise the indoor temperature, thereby achieving the heat preservation effect, and the air after heat dissipation by the heating tube 300 is discharged to the outside from the smoke tube 400.

As shown in fig. 5, in some embodiments of the present utility model, the position of the air outlet 130 is not lower than the position of the combustion chamber 710, that is, the setting heights of the air inlet 530, the combustion chamber 710, and the air outlet 130 are sequentially increased, so as to enlarge the area where the biomass timber can be fully combusted, thereby improving the combustion efficiency of the biomass timber, and the flame is intensively guided to the air outlet pipe 600 under the driving of the air flow, so as to effectively inhibit the occurrence of backfire. However, in other embodiments, the location of the air outlet 130 may be lower than the location of the combustion chamber 710, which is not limited to the above embodiments.

As shown in fig. 1, in some embodiments of the present utility model, the heat pipe 300 continuously radiates heat to the room during the heat preservation period, and the surface temperature is high. In order to avoid direct contact between the user and the heating tube 300, an isolation net 800 is disposed on the periphery of the heating tube 300, the isolation net 800 is spaced from the heating tube 300 by a distance and surrounds the heating tube 300, and the mesh size of the isolation net 800 is not larger than the size of a finger, so as to prevent contact between a human body and the heating tube 300 and avoid scalding.

In some embodiments of the present utility model, in order to better support the combustion heat insulation apparatus, the furnace 100 and the heat generating pipe 300 are commonly connected to a bracket 900, and a roller 910 or a foot stand is connected to the bottom of the bracket 900. Regardless of whether the bottom of the stand 900 is connected with the roller 910 or the foot stand, the user can quickly move the combustion insulation apparatus to a desired position through the stand 900 without touching a location involving a high temperature.

The embodiments of the present utility model have been described in detail with reference to the accompanying drawings, but the present utility model is not limited to the above embodiments, and various changes can be made within the knowledge of one of ordinary skill in the art without departing from the spirit of the present utility model.
