During use, the gas is mixed with the air sent in by the blower and sent into the burner or multiple burners for further mixed combustion.

[0003] A Chinese utility model patent with announcement number CN218295805U discloses an assembled large-pot stove furnace and a large-pot stove, wherein the assembled large-pot stove furnace comprises a furnace body and a smoke exhaust ring separately arranged from the furnace body, wherein the furnace body is provided with a substrate layer and one or more layers of a heat insulation layer, a ceramic wool layer and a protective layer from the outside to the inside; a smoke exhaust port is provided on one side of the furnace body; the smoke exhaust port is arranged to align with the smoke exhaust ring; the substrate layer comprises a cylinder and an inclined surface or a pot bottom-imitation curved surface extending inward from the lower end of the cylinder; and the inner surface of the furnace body is a reflector.

[0004] Although the above-mentioned prior art can make the temperature in the furnace of a large pot stove more uniform and reduce energy waste, the pot used in the furnace of a large pot stove also has a large gravity and is not easy to lift. Since the pot is sealed with the top of the furnace, when ignited, the fuel in the furnace suddenly burns violently and the gas pressure changes suddenly, and in severe cases, the furnace may explode. Utility Model Content

[0007] As a further improvement of the above solution, the lifting mechanism includes a support ring, the top of the support ring is fixedly connected to a support column, and the four sides of the support ring are fixedly connected to sliders.

[0008] Through the above technical solution, when ignition is performed, the support ring drives the support column to move upward through the slider, thereby lifting the large pot and releasing the gas pressure in the furnace, preventing the furnace from exploding during ignition and improving safety.

[0009] As a further improvement of the above solution, the lifting mechanism also includes a sliding groove opened inside the support seat for the sliding block to slide, and a through hole corresponding to the support column is opened on the top of the support seat, and the support ring slides inside the sliding groove through the sliding block.

[0010] As a further improvement of the above scheme, the drive assembly includes an installation cavity arranged inside the support seat and a heat-resistant shell fixedly installed on the outside of the support seat, a motor is fixedly installed inside the heat-resistant shell, and the output end of the motor is transmission-connected to an eccentric disk arranged inside the installation cavity, and the eccentric disk is arranged corresponding to one of its sliders.

[0011] Through the above technical solution, the eccentric disk is driven to rotate by the rotation of the motor, so that the eccentric disk lifts the slider, thereby lifting the support ring. The eccentric disk completes the lifting and lowering of the support ring once every rotation of the eccentric disk.

[0012] As a further improvement of the above solution, the lower furnace body is arranged in a cone shape, and a fire viewing hole is provided on the surface of the lower furnace body, and a smoke exhaust port is provided on the surface of the upper furnace body opposite to the fire viewing hole.

[0013] Through the above technical solution, the fire viewing hole and the smoke exhaust port are correspondingly arranged, so as to facilitate checking the combustion status and smoke exhaust when the burner is burning.

[0014] As a further improvement of the above solution, the surfaces of the lower furnace body and the upper furnace body are both provided with a heat-insulating layer and a sound-insulating layer, and the heat-insulating layer is provided on the outer surface of the sound-insulating layer.

[0015] Through the above technical solution, the thermal insulation layer is used to prevent heat leakage and improve energy utilization. The sound insulation layer is centrifugal resin glass wool, which has heat-resistant and sound-absorbing effects and isolates combustion noise.

[0016] Compared with the prior art, the beneficial effects of the present invention are:

[0017] The utility model controls the rotation of the motor through a controller before ignition, and the rotation of the motor drives the eccentric disk to rotate in the installation cavity, thereby squeezing the slider, so that the slider drives the support ring to slide upward in the slide groove, drives the support column to extend out of the through hole to lift the large pot, release the gas pressure in the furnace, and then ignite. After the ignition is completed, the motor is continued to be controlled to rotate, so that the eccentric disk rotates to the initial position and the large pot falls. The design lifts the large pot before igniting the furnace to release the pressure in the furnace, prevents the furnace from exploding, and improves safety. BRIEF DESCRIPTION OF THE DRAWINGS
