The grate mechanism 2 includes a grate body 201. An air guide port 202 is opened in the inner cavity of the grate body 201. A discharge port 205 is opened on the left side of the inner cavity of the grate body 201. Limit blocks 206 are fixedly installed at both the front and rear ends of the grate body 201. A baffle 203 is fixedly installed at the left end of the grate body 201. The air guide port 202 is a trapezoidal groove, and the width of the bottom of the air guide port 202 is twice the width of the top. A limit groove 4 is opened in the inner cavity of the hearth bottom 1, and the limit groove 4 is slidably connected with the limit block 206. The other side of the baffle 203 is fixedly installed with a handle 204, and anti-slip lines are provided on the surface of the handle 204.

[0040] In this embodiment: By providing the grate mechanism 2, the normal function of the grate can be ensured. The discharge port 205 facilitates the discharge of the furnace ash, and the air guide port 202 ensures ventilation, facilitates combustion, and can increase the air intake. The bottom opening of the trapezoidal groove is relatively large, facilitating air intake, and the air is blown out from the top opening, which can increase the wind force and improve the combustion quality. The limiting groove 4 can guide and limit the limiting block 206, thereby stabilizing the grate mechanism 2. The handle 204 facilitates the user to pull out the grate mechanism 2 and the ash cleaning mechanism 3 from the furnace bottom 1. Embodiment

[0041] Refer to Figures 1-5 , a dust discharge port is provided at the bottom of the furnace bottom 1, and a dust baffle is provided at the bottom of the furnace bottom 1. An ash cleaning mechanism 3 is provided on the top of the grate body 201. The ash cleaning mechanism 3 includes an ash cleaning plate 301. The bottom of the ash cleaning plate 301 is fixedly installed with a guide block 302 through a connecting rod. A pull rod 304 is fixedly installed on one side of the guide block 302, and a heat insulation sleeve 305 is fixedly installed at the other end of the pull rod 304. A reserved groove 306 is provided on the top of the grate body 201. The number of the guide blocks 302 and the pull rods 304 is two each. Guide grooves 303 are provided at both the front and rear ends of the grate body 201, and the guide grooves 303 are slidably connected with the guide blocks 302. The top of the baffle 203 is parallel to the top of the ash cleaning plate 301, and a through groove for cooperating with the baffle 203 is provided at the left end of the furnace bottom 1.

[0042] In this embodiment: By providing the ash cleaning mechanism 3, by pulling the heat insulation sleeve 305, the furnace ash can be scraped out along the discharge port 205 through the ash cleaning plate 301, facilitating discharging. The reserved groove 306 facilitates the sliding of the connecting rod at the top of the guide block 302. The two guide blocks 302 and the pull rods 304 can make the ash cleaning plate 301 move more stably. The guide grooves 303 can guide the guide blocks 302 to move stably. The through groove can limit the baffle 203. The baffle 203 is parallel to the top of the ash cleaning plate 301, which can facilitate the overall entry and exit of the grate mechanism 2 and the ash cleaning mechanism 3. By opening the dust baffle, the furnace ash can be discharged along the dust discharge port.

[0043] The implementation principle of the present utility model is as follows: During use, pulling the heat insulation sleeve 305 drives the pull rod 304 to move, the pull rod 304 drives the guide block 302 to move, and the guide block 302 drives the ash cleaning plate 301 to move through the connecting rod at the top, which can scrape off the furnace ash on the top of the grate body 201. The falling ash drops along the discharge port 205 and can also drop along the air guide port 202. Pulling the handle 204 can drive the baffle 203 to move, the baffle 203 drives the grate body 201 to move, and the limiting block 206 slides in the limiting groove 4, which can pull out the entire grate mechanism 2 and the ash cleaning mechanism 3 from the furnace bottom 1, thus facilitating the maintenance of the grate body 201.
