[0002] A glass-ceramic heater is an electric heating device that uses glass-ceramic material as the surface layer. It combines the excellent physical and chemical properties of glass-ceramic with the convenience of electric heating technology and is widely used in laboratories, industrial processing, and household applications. Glass-ceramic heaters usually achieve heating functions by printing heating resistor films or other electric heating elements (such as metal thermal conductors, ceramic PTC heating elements, carbon fiber heating wires, etc.) on a glass-ceramic substrate.

[0022] By introducing current into the semiconductor conductor 23, the current interacts with the lattice in the semiconductor conductor 23 to generate heat energy, which is then quickly conducted to the surface through the microcrystalline glass plate 21 and heats the surrounding air by radiation. This heating method can greatly improve the electric heating efficiency and can quickly heat up the indoor temperature; the thermal insulation box 1 can achieve a good thermal insulation effect, which can avoid the loss of heat energy derived from the microcrystalline glass plate 21, thereby reducing the consumption of electrical energy inside the semiconductor conductor 23, and also greatly reducing the heating cost. The hot air inside the thermal insulation box 1 can be blown to the corresponding spatial area through the air blowing mechanism 4, and the air guide mechanism 6 will diffuse the hot air evenly, so that the indoor temperature can be quickly raised.

[0023] Furthermore, the blower mechanism 4 includes a blowing impeller 41, which is rotatably connected to one end of the fixed plate 3, and one end of the bottom of the fixed plate 3 is rotatably connected to a cam 42 coaxially fixedly connected to the blowing impeller 41, and the outer edge of the cam 42 is rotatably connected to a first connecting rod 43, and one end of the first connecting rod 43 away from the cam 42 is hinged to a movable rod 44, and one end of the movable rod 44 is provided with a heat driving member 45 for driving the movable rod 44 to reciprocate. The movable rod 44 is driven to reciprocate by the heat driving member 45, which causes the first connecting rod 43 to drive the cam 42 to rotate, so that the blowing impeller 41 rotates, so that the pressure at the air outlet 5 changes, so that the hot air inside the thermal insulation box 1 is discharged outward through the air outlet 5.

[0024] Furthermore, the heat drive member 45 includes a cylinder 451, one end of which is fixedly connected to the side wall of the heat preservation box 1, a piston 452 is slidably connected to the inner side of the cylinder 451, a movable rod 44 passes through the side wall of the cylinder 451 and is slidably connected to the side wall of the cylinder 451, an end of the movable rod 44 away from the first connecting rod 43 is fixedly connected to the piston 452, the inner side of the cylinder 451 is filled with a heat-sensitive gas 458, one end of the cylinder 451 is fixedly connected to an exhaust pipe 453 that communicates with the inside of the cylinder 451, and the inlet end of the exhaust pipe 453 is fixedly connected to a A cooler 455 for cooling the temperature is fixedly connected to the outside of the heat preservation box 1, an outlet end of the cooler 455 is fixedly connected with an air inlet pipe 456, an outlet end of the air inlet pipe 456 is fixedly connected to the other end of the cylinder 451 and communicates with the interior of the cylinder 451, an exhaust check valve 454 is fixedly connected to the exhaust pipe 453, an air inlet check valve 457 is fixedly connected to the air inlet pipe 456, a fluid flow direction of the exhaust check valve 454 is introduced from the interior of the cylinder 451 into the exhaust pipe 453, and a fluid flow direction of the air inlet check valve 457 is introduced from the intake pipe 456 into the interior of the cylinder 451.

[0025] By introducing current into the semiconductor conductor 23, the current interacts with the lattice in the semiconductor conductor 23 to generate heat energy, so that the temperature inside the heat preservation box 1 rises rapidly, and the internal temperature of the cylinder 451 also rises. At this time, the heat-sensitive gas 458 inside the cylinder 451 expands after being heated, so that the pressure inside the cylinder 451 increases, which causes the piston 452 to slide until the piston 452 moves to one side of the exhaust pipe 453. At this time, the heat-sensitive gas 458 will be discharged from the exhaust pipe 453 and introduced into the cooler 455, so that the cylinder The pressure inside the cylinder 451 decreases, causing the piston 452 to slide in the opposite direction. The thermosensitive gas 458 is cooled by the cooler 455 and is re-introduced into the cylinder 451. When the thermosensitive gas 458 heats up again, the piston 452 can slide. This cycle continues, and the piston 452 slides back and forth, which causes the movable rod 44 to reciprocate, causing the first connecting rod 43 to drive the cam 42 to rotate, causing the blowing impeller 41 to rotate, thereby changing the pressure at the air outlet 5, so that the hot air inside the insulated box 1 is discharged outward through the air outlet 5.

[0026] Furthermore, the air guide mechanism 6 includes a plurality of air guide plates 61, which are rotatably connected to the inner side of the air outlet 5 and are equidistantly distributed along the length direction of the air outlet 5. One end of the plurality of air guide plates 61 is fixedly connected to an incomplete gear ring 65. A guide rail 62 is fixedly connected to the inner wall of the thermal insulation box 1. A movable frame 63 is slidably connected to the inner side of the guide rail 62. The vertical section of the air guide plate 61 is a fan-shaped structure that is narrow at the top and wide at the bottom. The vertical section of the movable frame 63 is an L-shaped structure.

The plurality of racks 64 are meshed with the corresponding incomplete gear rings 65. The bottom end of the movable frame 63 is provided with a transmission mechanism 7 that cooperates with the rotation of the blowing impeller 41 to drive the movable frame 63 to slide back and forth.

[0027] The rotation of the blowing impeller 41 can make the transmission mechanism 7 drive the movable frame 63 to slide back and forth, so that all the racks 64 can reciprocate in the horizontal direction, and all the incomplete gear rings 65 can reciprocate, so that all the air guide plates 61 can swing back and forth, so that the hot air discharged from the air outlet 5 can be evenly diffused, thereby allowing the indoor temperature to rise quickly.

The bottom of the fixed plate 3 is rotatably connected to a second bevel gear 74 that is meshed with the first bevel gear 73, and one side of the second bevel gear 74 is coaxially fixedly connected to an eccentric wheel 75, and the outer edge of the eccentric wheel 75 is rotatably connected to the bottom end of the second connecting rod 66.

[0029] Working principle: by introducing current into the semiconductor conductor 23, the current interacts with the lattice in the semiconductor conductor 23 to generate heat energy, which is then quickly conducted to the surface through the microcrystalline glass plate 21 and heats the surrounding air by radiation, so that the temperature inside the heat preservation box 1 rises rapidly. The heat preservation box 1 can achieve a good heat preservation effect, thus avoiding the loss of heat energy conducted by the microcrystalline glass plate 21, thereby reducing the consumption of electric energy inside the semiconductor conductor 23; When the temperature in the heat preservation box 1 rises, the internal temperature of the cylinder 451 will rise. At this time, the heat-sensitive gas 458 in the cylinder 451 expands after being heated, which increases the pressure inside the cylinder 451, causing the piston 452 to slide until the piston 452 moves to one side of the exhaust pipe 453. At this time, the heat-sensitive gas 458 will be discharged from the exhaust pipe 453 and introduced into the cooler 455, so that the pressure inside the cylinder 451 decreases, thereby causing the piston 452 to slide in the opposite direction. The heat-sensitive gas 458 is cooled by the cooler 455 and then re-introduced into the cylinder 451. When the heat-sensitive gas 458 heats up again, the piston 452 can slide. In this cycle, the piston 452 slides back and forth, which causes the movable rod 44 to reciprocate, so that the first connecting rod 43 drives the cam 42 to rotate, causing the blowing impeller 41 to rotate, thereby changing the pressure at the air outlet 5, so that the hot air inside the heat preservation box 1 is discharged outward through the air outlet 5; When the blowing impeller 41 rotates, it will drive the first transmission gear 71 to rotate, so that the second transmission gear 72 drives the first bevel gear 73 to rotate, so that the second bevel gear 74 drives the eccentric wheel 75 to rotate synchronously, and the second connecting rod 66 drives the movable frame 63 to slide back and forth, which makes all the racks 64 reciprocate in the horizontal direction, and also makes all the incomplete gear rings 65 reciprocate, so that all the air guide plates 61 swing back and forth, so that the hot air discharged from the air outlet 5 can be evenly diffused, thereby allowing the indoor temperature to rise quickly.
