[0044] The mesh ash pan assembly is arranged in the furnace cavity 2 and includes an ash pan 12 mounted on the basin body 9 and a supporting mesh 13 arranged above the ash pan 12.

[0045] The base 8 can be inverted on the supporting step 7 to receive the basin body 9 and the plurality of supporting feet 10 into the furnace cavity 2. The mesh ash pan assembly can be turned over and mounted on the plurality of supporting feet 10. The fire concentrating ring 4 can be inverted on the end edge 3 so that the retaining ring 6 extends into the furnace cavity 2 and is located outside the ash pan 12.

[0046] In the above technical solution, the entire firewood stove is divided into a detachable fire concentrating ring, furnace body, base and mesh ash pan assembly. Among them, the fire concentrating ring is mounted on the end edge of the furnace body, the furnace body is mounted on the base, and the mesh ash pan assembly is arranged in the furnace cavity of the furnace body and mounted on the base. The base includes a basin body and a plurality of supporting feet arranged at the bottom of the basin body. The supporting ring on the basin body cooperates with the supporting step, so that the furnace body can be stably mounted on the base and will not shake. The supporting mesh of the mesh ash pan assembly is used to support the combustibles, and the ash pan is mounted on the basin body and is used to collect the fallen combustion ashes.

[0047] During storage, the basin body and the supporting feet are also inverted into the furnace cavity through the cooperation of the supporting ring and the supporting step. The mesh ash pan assembly can be turned over and mounted on the supporting feet. Similarly, the fire concentrating ring is inverted into the furnace cavity through the cooperation of the mounting ring and the end edge, and the retaining ring is placed well outside the ash pan to prevent the mesh ash pan assembly from coming out. After storage, the entire firewood stove is packed and taken away through a packaging bag, which is very convenient. Moreover, the furnace body, fire concentrating ring, base and mesh ash pan assembly are all independent parts, which are more labor-saving and convenient for users to carry and assemble.

[0048] As Figures 6 - 7 shown, a lapping step 14 is formed on the inner side of the supporting ring 11. The upper end edge of the ash pan 12 is formed with a lapping ring 15 that is mounted on the lapping step 14, and the pan body of the ash pan 12 falls into the basin body 9. In this technical solution, the lapping step cooperates with the lapping ring on the ash pan to prevent the circumferential shaking of the mesh ash pan assembly and improve the stability.

[0049] As Figure 8 and Figure 16As shown, a connecting edge 16 is formed upward at the outer end edge of the overlapping ring 15, and a first circular rib 17 is formed at the upper end of the connecting edge 16. The lower end of the support mesh 13 is fixedly attached to the overlapping step 14, and the edge of the support mesh 13 extends upward to form a flanging 18 which is fixedly attached to the connecting edge 16. The outer end face of the support leg 10 is configured as an inclined arc surface 19. When the support leg 10 is received into the furnace cavity 2, the bottom surface of the support leg 10 abuts against the support mesh 13, and the arc surface 19 abuts against the first circular rib 17. In this technical solution, the support mesh is fixedly welded to the ash accumulation tray at two places, namely the connecting edge and the overlapping step, to form an integral body, and a first circular rib is provided, so the structure is stable. When the mesh ash tray assembly is taken out and inverted onto the support legs, the outer arc surface of the support legs abuts against the inner end of the first circular rib, so that the mesh ash tray assembly will not shake circumferentially after being received, thus improving stability.

[0050] As Figure 7 shown, the basin body 9 is frustum-shaped, the inner diameter of the basin body 9 gradually decreases from top to bottom, and a plurality of first air inlet holes 20 are provided on the bottom surface of the basin body 9. A plurality of ash falling holes 21 are provided on the support mesh 13 so that ashes can fall into the ash accumulation tray 12, and a plurality of through holes 24 are provided on the side wall of the ash accumulation tray 12 and are communicated with the ash falling holes 21 and the first air inlet holes 20. In this technical solution, the basin body is frustum-shaped with an inner diameter gradually decreasing from top to bottom, which is more convenient to be inverted and installed into the furnace cavity; external air enters the basin body through the first air inlet holes at the bottom, enters the ash accumulation tray through the through holes, and then enters the furnace cavity through the ash falling holes to promote the combustion of firewood.

[0051] As Figure 8 shown, the support mesh 13 is stepped, and the formed multi-layer steps are regularly arranged from high to low from inside to outside, and a plurality of ash falling holes 21 are regularly provided on the multi-layer steps. In this technical solution, the stepped shape of the support mesh can make the combustibles be arranged obliquely on the support mesh, increasing the gap between the ash falling holes and the combustibles, and making the combustion more complete.

[0052] As Figure 8 shown, a connecting column 22 is fixedly penetrated through the middle of the support mesh 13, and a pull ring 23 is formed at the upper end of the connecting column 22. In this technical solution, the arrangement of the connecting column and its pull ring enables users to easily take out, empty the ash, receive, and carry the entire mesh ash tray assembly through the pull ring.

[0053] As Figure 8 shown, the inner diameter of the ash accumulation tray 12 gradually becomes smaller from top to bottom, and the plurality of through holes 24 are circumferentially and regularly arranged on the side wall of the ash accumulation tray 12. In this technical solution, the inner diameter of the ash accumulation tray gradually becomes smaller from top to bottom, which can increase the gap distance between the through holes and the side wall of the basin body, making the air intake easier and more convenient, and making the combustion in the furnace cavity more complete.

[0054] As Figure 9As shown, an arc-shaped retaining edge 25 is formed on the upper end edge of the retaining ring 6 and slopes downward and inward. When the fire concentrating ring 4 is buckled onto the furnace body 1, the arc-shaped retaining edge 25 is correspondingly located outside the ash collecting tray 12. In this technical solution, the setting of the arc-shaped retaining edge on the fire concentrating ring can cooperate with the inclined side wall of the ash collecting tray to prevent the mesh ash tray assembly from swinging greatly along the opening direction after being stored.

[0055] As Figure 11 shown, the furnace body 1 includes an outer furnace wall 26 and an inner furnace wall 27 which are hermetically connected at the upper and lower ends. An air inlet channel 28 is formed between the outer furnace wall 26 and the inner furnace wall 27. The lower part of the side wall of the outer furnace wall 26 is recessed into the inner wall of the outer furnace wall 26 to form a reinforcing rib 29 in the air inlet channel 28. In this technical solution, the outer furnace wall is recessed on the outer wall and a reinforcing rib is formed on the inner wall, which can improve the structural strength of the outer furnace wall and extend its service life.

[0056] As Figure 3 shown, a plurality of second air inlet holes 30 communicating with the air inlet channel 28 are circumferentially provided on the side wall of the outer furnace wall 26 below the reinforcing rib 29. A plurality of air outlet holes 31 communicating the furnace cavity 2 and the air inlet channel 28 are circumferentially provided on the upper end side wall of the inner furnace wall 27; the end edge 3 is formed at the upper end of the inner furnace wall 27, and a second circular rib 32 is formed upward on the edge of the end edge 3; the supporting step 7 is formed at the lower end of the inner furnace wall 27, and a third circular rib 33 is formed on the lower end edge of the inner furnace wall 27. In this technical solution, external air enters the air inlet channel through the second air inlet holes and then through the air outlet holes, improving the combustion effect; in addition, the second circular rib can prevent the fire concentrating ring from coming off and improve the structural strength; the third circular rib can improve the structural strength of the lower end of the inner furnace wall.

[0057] In this specific embodiment, aiming at the problem that the existing wood stove is inconvenient to carry and transport due to its large volume and weight, the above solution divides the whole wood stove into a detachable fire concentrating ring, furnace body, base and mesh ash tray assembly. Among them, the fire concentrating ring is erected on the end edge of the furnace body, the furnace body is erected on the base, and the mesh ash tray assembly is arranged in the furnace cavity of the furnace body and erected on the base; the base includes a basin body and a plurality of supporting feet arranged at the bottom of the basin body. The supporting ring on the basin body cooperates with the supporting step, so that the furnace body can be stably erected on the base without shaking; the supporting net of the mesh ash tray assembly is used to support the combustibles, and the ash collecting tray is erected on the basin body for collecting the fallen combustion ashes.

[0058] When storing, the basin body and the supporting feet are also buckled in the furnace cavity through the cooperation of the supporting ring and the supporting step, and the mesh ash pan assembly can be erected on the supporting feet in reverse. The fire concentrating ring is also buckled in the furnace cavity through the cooperation of the mounting ring and the end edge. The retaining ring and the arc-shaped retaining edge are placed outside the ash pan to prevent the mesh ash pan assembly from slipping out and shaking. After storage, the whole wood stove is packed and taken away with a packaging bag, which is very convenient. Moreover, the stove body, the fire concentrating ring, the base and the mesh ash pan assembly are all independent parts, which are more labor-saving and convenient for users to carry, and are also very convenient to assemble.
