When installing the isolation part 701, the upper end of the isolation part 701 is first clamped on the first buckle plate 702, and then the lower end of the isolation part 701 is clamped into the second buckle plate 703, and then the screws are tightened to complete the locking installation of the isolation part 701. It is easy to assemble and disassemble and simple to operate.

[0020] It should be noted that the reference Fig.12 , Fig.13 The outer support plate 5 is fixed to the top of the outer cover plate 2, the plate surface of the inner support plate 6 is supported and connected with multiple grille members 7, cover pipes and multiple first support columns 8, a positioning assembly 15 is arranged between the inner support plate 6 and the outer support plate 5, the positioning assembly 15 includes a group of slide bars 1502 uniformly fixed to the sliding surface of the inner support plate 6, a group of slide rails 1501 extending in the vertical direction of the gas heating stove are fixed at the inner wall of the outer cover plate 2 corresponding to the group of slide bars 1502, a group of slide rails 1501 and the inner wall of the outer cover plate 2 are fixedly connected with a skeleton middle tube 1503, a group of slide rails 1501 are opened at the upper position of the outer support plate 5, and a sliding baffle 1506 arranged in the first direction is slidably connected inside the notch, refer to Figure 3 , a positioning lever 1504 is fixedly connected to the side of the sliding baffle 1506 away from the inside of the outer cover plate 2, and a fixed baffle 1505 is fixedly connected between the positioning lever 1504 and the sliding baffle 1506. A paddle sliding groove is opened on the surface of the outer cover plate 2 where the positioning lever 1504 passes through, so that the positioning lever 1504 can drive the sliding baffle 1506 to slide on the skeleton middle tube 1503 through the fixed baffle 1505. When the heat transfer component and the radiation component are in the stretched use state, the grille member 7 or the first support column 8 is first pulled to make the inner support plate 6 move up in the upright direction, and the sliding bar 1502 at the inner support plate 6 moves to above the notch of the slide rail 1501, and the positioning lever 1504 drives the sliding baffle to move and support and connect to the lower end of the sliding bar 1502, completing the upward movement and stretched use state of the heat transfer component and the radiation component, and the reverse operation is performed to complete the retracted placement state.

[0021] refer to Figure 5 and Fig.11 The radiation component is arranged above the heat transfer component in the vertical direction. The radiation component includes a guide mechanism component 9, a heat dissipation cover 16, a top cover mechanism component 10 and a current limiting plate component 11. The guide mechanism component 9 has a bottom plate and a peripheral wall surrounding and connecting the bottom plate. The peripheral wall is provided with a plurality of outflow holes. The upper ends of the plurality of first support columns 8 are connected to the bottom plate. The heat dissipation cover 16 is directly opposite to the upper end of the cover pipe. The heat dissipation cover 16 is located inside the guide mechanism component 9 and is surrounded by the peripheral wall. The top cover mechanism component 10 covers the peripheral wall in the vertical direction. The current limiting plate component 11 is arranged above the peripheral wall in the vertical direction and surrounds Around the top cover mechanism component 10, the flow limiting plate 11 extends outward along a first direction, and the first direction is perpendicular to the upright direction; the surface of the flow limiting plate 11 and the surface of the flow guide mechanism component 9 are coated with a first temperature-resistant powder layer, and the surfaces of the multiple first support columns 8 and the surfaces of the multiple grille components 7 are coated with a second temperature-resistant powder layer. The refractoriness of the first temperature-resistant powder layer is higher than that of the second temperature-resistant powder layer, which saves the cost of using the coating material to a certain extent. Exemplarily, the temperature-resistant powder material includes but is not limited to alumina, silicates, aluminum silicate, magnesium silicate, etc.

[0022] The surface of the heat dissipation cover 16 is provided with mesh holes suitable for the outflow of hot air; The top cover mechanism component 10 includes a cover body 101 and a side plate 102. The cover body 101 is fixedly connected to a heat insulation plate 12 arranged on the top of the inner wall of the heat dissipation cover 16 by bolts; the cover body 101 and the bottom plate and the surrounding wall of the air guide mechanism component 9 enclose a retention space for retaining the hot air flowing out of the heat dissipation cover 16; It should be noted that the flame at the fire outlet is transmitted from the bottom to the top of the hood tube, and the hot air flow of the flame at the top enters the interior of the heat dissipation hood 16 and accumulates. The hot air flow at the top is blocked by the heat insulation plate 12, so that the hot air flow will be retained in the interior of the heat dissipation hood 16, forming an air flow buffer space to prevent it from being directly sprayed out from the top of the hood tube. At the same time, the gas in the hood tube is more fully burned under the retention effect, producing an effect similar to secondary combustion, effectively improving the heat generation efficiency of the gas. In addition, when the internal pressure inside the heat dissipation hood 16 continues to increase, the hot gas will overflow from the mesh surface of the heat dissipation hood 16. After the hot gas is burned in the hood tube, it will flow out of the heat dissipation hood 16 and enter the retention space between the heat dissipation hood 16 and the guide mechanism component 9. The hot gas will be more fully burned or re-combusted in the retention space. Burning, and effectively improve the heat generation efficiency of the gas, the hot air will also be evenly mixed in the retention space and flow out from the multiple outlet holes of the guide mechanism component 9 to the outside of the gas heating furnace more slowly, and with the guidance of the limiting plate 11, the hot air can surround the heat transfer component to achieve the heating effect. Since the hot air is more evenly dissipated from the radiation component to the outside of the gas heating furnace and the speed at which the hot air flows out of the gas heating furnace is also slower, it can effectively surround the heat transfer component within an appropriate distance range and for a longer time, slowing down the dissipation speed of the hot air outside the gas heating furnace, and solving the problem that the hot air was directly sprayed from the heat dissipation cover 16 to the outside of the gas heating furnace at a faster speed and uneven heat, resulting in a fast dissipation speed of the hot air outside the gas heating furnace and a poor heating effect.

[0023] Due to the setting of the mesh, the mesh size is much smaller than the outlet hole size, and the outflow pressure of the hot air flow is weakened in sequence under the setting of the mesh and the outlet hole, so that the outflowing airflow pressure is weakened, and the hot air flow will flow out slowly and orderly, reducing the ejection force of the hot air flow and effectively improving the safety of use.

[0024] The cover body 101 has a top plate and a side wall surrounding and connected to the top plate, and the side plate 102 surrounds and connects to the lower end of the side wall and forms a mounting groove with the lower end of the side wall, and the mounting groove is used to install the current limiting plate 11; The current limiting plate 11 includes a plurality of arc plates 111 spliced ​​into a ring shape. The arc plates 111 are bent and extended with the vertical direction facing upward and in the first direction, that is, the whole is in an inverted cone shape, and no screws are used for connection. Specifically, the arc plates 111 are inserted into the installation groove, and a plug-in piece 112 is fixed at a splicing position on one side of the arc plates 111. The plug-in piece 112 has the same curvature as the arc plates 111, and the plug-in piece 112 is protruding from the upper surface of the arc plates 111; A group of female grooves 113 are provided on the upper surface of the plug 112, and male buckles 114 are fixed to the upper surface of the joint on the other side of the arc plate 111 where the plug 112 is not provided, corresponding to the position of the female grooves 113. The male buckle 114 of one arc plate 111 is sequentially plugged into the female groove 113 of another arc plate 111 to form a connection setting of the current limiting plate 11, which not only saves the use of screws, but also makes the overall appearance more beautiful on the basis of no screws.

[0025] The size of the current limiting plate 11 can be selected according to actual usage requirements. After the installed current limiting plate 11 is inserted into the installation groove, the fixed connection of the arc plate 111 is completed by providing a fixing plate 13 corresponding to the position and number of the arc plate 111; the arc surface setting of the arc plate 111 allows the hot air flow to expand and adjust the radiation area to a corresponding degree according to the curvature and area size of the arc surface setting.

[0026] The door panel mechanism 3 includes a rotating door 301, a plug rod 303, a first limit block 305, and a second limit block 306. The rotating door 301 is rotatably connected to one side of the outer wall of the outer cover plate 2. An annular groove 302 is provided on the surface of the rotating door 301 away from the rotating connection.

The surfaces of the short sections on the same straight line are provided with insertion holes, and the insertion rod 303 is inserted into the insertion holes. The bottom of the insertion rod 303 is conical, which facilitates the insertion process of the insertion rod 303. The insertion rod 303 passes through one side of the annular groove 302 and is fixedly connected to a hand-held portion 304; by moving the hand-held portion 304 up and down, the hand-held portion 304 will drive the insertion rod 303 to move up and down, so that the insertion rod 303 is pulled out or inserted into the socket, completing the opening or closing of the rotating door 301.
