DETAILED DESCRIPTION OF THE EMBODIMENTS

[0019] The present utility model will be further described below in conjunction with the accompanying drawings and specific embodiments.

[0020] Reference Figures 1 to 6, this embodiment provides a heat-insulating stove, which includes a stove body 1, an opening 2 provided at the top of the stove body 1, a heat-insulating ring 3 provided at the opening 2 on the top surface of the stove body 1, and a stove basin 4 detachably provided inside the heat-insulating ring. The heat-insulating ring 3 fits with the opening 2 at the top of the stove body 1. An extension ring 301 extending to the top surface of the stove body 1 is provided on the outer side of the heat-insulating ring 3. The heat-insulating ring 3 and the stove basin 4 are arranged at intervals.

[0021] Preferably, steel sheets are buried inside the stove body, and a bolt is provided on the steel sheet to connect with the stove basin. In the actual use process, it can also be directly connected to the heat-insulating ring, and specific adjustments are made according to the shape of the stove body to achieve the fixation of the stove basin.

[0022] A lighting system is built inside the top of the stove basin. During use, there is a continuously burning flame in the middle of the top of the stove basin. In the past, the stove was made of a magnesium oxide mixed material. The applicant found through long-term use that although the magnesium oxide mixed material has good heat insulation, it is prone to cracking after long-term use. The existing stove has been replaced with a fiberglass material, which is not prone to cracking after long-term use. However, in extreme cases, when the stove basin is continuously lit and the wind blows downward towards a position on the top surface of the stove body all the time, there is a problem that the interval position between the top surface of the stove body and the stove basin is melted by the influence of the flame. By setting a heat-insulating ring between the stove basin and the stove body, and the top surface of the heat-insulating ring has an extension ring that fits with the top surface of the stove body. When the flame blows downward towards a position on the top surface of the stove body all the time, the heat of the flame will be evenly conducted and dispersed through the heat-insulating ring, avoiding local heat melting in extreme cases.

[0023] The outer side of the heat-insulating ring 3 is sprayed with fireproof paint, which can extend the service life of the heat-insulating ring. The material of the heat-insulating ring is preferably aluminum. Aluminum materials are not easy to rust and have low procurement costs, which is conducive to mass production. It can also be replaced with iron, stainless steel or other materials, which are all existing materials and will not be elaborated here.

[0024] The extension ring 301 is bent downward by 180 degrees to form a first bending part 302. The end of the first bending part 302 is bent downward by 90-100 degrees to form a second bending part 303. The second bending part 303 is arranged at intervals with the first bending part 302. Through the setting of the first bending part and the second bending part, there is an interval gap between the first bending part and the extension ring, and air can isolate part of the heat. The temperature of the second bending part is lower when heated, avoiding the high temperature caused by the direct contact between the top surface of the stove body and the extension ring.

[0025] Reference Figure 6 , a hollow copper plate 304 is provided between the extension ring 301 and the first bending part 302, and a heat-conducting liquid 305 is provided inside the hollow copper plate 304. Due to the setting of the hollow copper plate, the hollow copper plate and the internal heat-conducting liquid have good heat conductivity, evenly conducting the locally heated temperature of the extension ring to other positions, reducing the local high temperature of the extension ring in extreme cases. The hollow copper plate and the heat-conducting liquid are both existing conventional technologies and will not be elaborated here.

[0026] A heat insulation board 5 is provided between the extension ring 301 and the top surface of the furnace body 1. A groove 101 is provided on the top surface of the furnace body 1 at the position of the extension ring 301. With the heat insulation board, the extension ring contacts the furnace body through the heat insulation board. The heat insulation board has good flame retardancy and heat insulation performance. Since the top surface of the furnace body has a wood grain decoration, direct contact or being close to the extension ring is likely to cause melting and cracking. The heat insulation board has good flame retardancy and will not crack under temperature changes, which is beneficial to protecting the extension ring.

[0027] The heat insulation board 5 includes a first aluminum plate 501 that fits with the extension ring 301, a second aluminum plate 502 that fits with the groove 101, an I-shaped part 503 provided between the first aluminum plate 501 and the second aluminum plate 502, a rock wool board 504 and a calcium silicate board 505 provided between the first aluminum plate 501 and the second aluminum plate 502, and a polyurethane edge seal 506 provided on the sides of the first aluminum plate 501 and the second aluminum plate close to the heat insulation ring 3.

[0028] The first aluminum plate can protect the surface of the rock wool board, and the second aluminum plate can protect the calcium silicate board, preventing the problem that the extension ring is easily separated from the rock wool board directly. And the I-shaped part supports between the first aluminum plate and the second aluminum plate, preventing the extension ring from bearing a large weight and causing the rock wool board and the calcium silicate board to crack and be damaged. The rock wool board has a low thermal conductivity coefficient, can effectively block heat conduction, avoid the heat of the extension ring being transferred to the top surface of the furnace body, belongs to a non-combustible material, can withstand high temperatures, does not burn when encountering fire, and does not produce toxic gases, with good safety. When the calcium silicate board is used as the lower layer board, the calcium silicate board has better strength and hardness. When handling and being pressed, the calcium silicate board at the bottom bears more weight and impact, which can improve the impact resistance of the heat insulation board. And the calcium silicate board has good waterproof and moisture-proof properties, avoiding the influence of the humidity inside the furnace body on the performance. The polyurethane edge seal seals the rock wool board and the calcium silicate board, providing protection for the rock wool board and the calcium silicate board. The polyurethane edge seal has a very low thermal conductivity coefficient, can effectively block the penetration of air, moisture and dust, keep the environment of the rock wool board and the calcium silicate board clean and dry, and make the heat insulation board durable when used in cooperation with the furnace body.
