For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.

[0017] As attached Figure 1 and Figure 2 As shown, the utility model provides a wood-fired heating stove, comprising a storage box 1, a combustion furnace 2 and a chimney pipe 3, wherein the combustion furnace 2 is arranged on the storage box 1, the combustion furnace 2 comprises an outer shell 21, a door 22, a combustion chamber 23 and a drawer-type ash box 24, one side of the combustion chamber 23 is provided with an opening corresponding to the door 22, the combustion chamber 23 except the open side, the other five sides are arranged in the outer shell 21 through a plurality of isolation strips 25, the door 22 is connected to the outer shell 21 through a hinge, one end of the chimney pipe 3 is connected to the combustion chamber 23 of the combustion furnace 2, and the other end extends outside the house, a baffle 26 is arranged in the combustion chamber 23, and the baffle 26 is located below the chimney pipe 3, the drawer-type ash box 24 is arranged below the combustion chamber 23, the lower wall of the combustion chamber 23 is provided with an ash leakage groove, and a ventilation channel 27 is respectively provided on both sides of the drawer-type ash box 24;

[0018] Specifically, the combustion furnace 2 is arranged on the storage box 1, and some tools or firewood for burning can be placed in the storage box 1. For example, some firewood that is not too dry can be placed in the storage box 1 first. When the combustion furnace 2 is burning, the temperature can be transmitted down to dry the firewood that is not too dry, which can also reduce the generation of smoke; the combustion furnace 2 and the outer shell 21 are connected by an isolation strip 25 to avoid directly roasting the outer shell 21, reduce the temperature of the outer shell 21, and reduce the degree of burns caused by users accidentally touching the outer shell 21; the baffle 26 is arranged in the combustion chamber 23, and the baffle 26 is located below the opening of the connection between the chimney pipe 3 and the combustion chamber 23. When burning firewood, the height of the flame can be controlled. Through the indoor and outdoor pressure, the flame is blocked by the baffle 26 and is guided to bypass the baffle 26, and the smoke is discharged from the chimney pipe 3.

[0019] Preferably, the housing 21 is provided with air holes, and the air holes are used to dissipate the temperature in the combustion chamber 23 to warm the room.

[0020] Preferably, an observation window 221 is provided on the door 22 of the combustion furnace 2. The observation window 221 is made of transparent glass material, which is convenient for the user to observe the situation in the combustion chamber 23 and to add firewood in time.

[0021] Preferably, a kettle seat 201 is provided on the combustion furnace 2, and the kettle seat 201 is a through hole provided on the upper end surface of the outer shell 21. When the kettle is placed on the kettle seat 201, the bottom of the kettle is connected to the upper end surface of the combustion chamber 23, which is convenient for heat transfer and boiling water.

[0022] Preferably, a water tank 4 is provided on the chimney pipe 3, and the water tank 4 is provided with a water inlet and a water outlet. The water tank 4 can be used to boil some water with low purity requirements, such as for washing hands. In addition, a vent hole can be provided on the water tank 4. When the water in the water tank 4 is boiled to a high temperature, water mist will be discharged from the vent hole, which can increase the indoor humidity.

[0023] Preferably, a protective cover 31 is provided on the chimney pipe 3. It is understandable that, although the chimney pipe 3 is used to exhaust smoke, after long-term use, dirt will inevitably accumulate on the outer wall of the chimney pipe 3. The dirt is very light and may float indoors when blown by the wind. The purpose of providing the protective cover 31 is to prevent the dirt from floating indoors.

[0024] In summary, the firewood heater provided by the utility model puts firewood into the combustion chamber 23 for combustion, and the door 22 of the combustion furnace 2 can be closed to prevent most of the smoke from spreading into the house, and then the smoke is drained from the chimney pipe 3 through the baffle 26, thereby improving the indoor environment.

[0025] It is understandable that those skilled in the art can make equivalent substitutions or changes based on the technical solution and utility model concept of the utility model, and all these changes or substitutions should fall within the protection scope of the claims attached to the utility model.
