The present invention utilizes the temperature difference to generate electricity through the temperature difference heating unit, charges the power storage unit, and the power storage unit supplies power to the display unit. Since the movable drawer is independent of the outer shell, it is difficult to set a pipeline connected to the outer shell on the movable drawer, and the display unit is used to display the heating progress or temperature, and no additional line connected to the outer shell is required, which simplifies the line and saves energy. Preferably, a fingerprint unlocking module is installed in the display unit. The present invention is provided with a fingerprint unlocking module, which can lock and unlock the movable drawer or the air fryer, thereby preventing children from accidentally operating the high-temperature air fryer and reducing the risk of burns. The present invention solves the defect that the handle of the existing air fryer with steam function does not have any function set in it and has a single structure.

[0006] Optionally, the air inlet pipe is connected to the bottom end of the heat exchange cylinder, and the air outlet pipe is connected to the top end of the heat exchange cylinder.

[0007] Optionally, a first one-way valve is installed on the air inlet pipe, and a second one-way valve is installed on the air outlet pipe.

[0008] Optionally, a piston is provided in the heat exchange cylinder, and a spring is provided between the piston and the bottom end of the heat exchange cylinder.

[0009] Optionally, a first rack is provided on the top of the piston, and a plurality of gears meshing with the first rack are installed on the side of the first rack close to the temperature difference heating unit. A rotating shaft is provided at the center of the gear, and an arc-shaped guide plate is installed on the rotating shaft, and the belly of the guide plate faces upward.

[0010] Optionally, a slide groove is provided on one side of the heat exchange tube close to the temperature difference heating unit, a slide plate is provided in the slide groove, a second rack is provided on the upper part of the slide plate, and the second rack is meshed with the gear. An air guide groove is provided in the slide plate, and the second rack is installed in the air guide groove.

[0011] Optionally, a limiting assembly is provided in the air guide groove, and the limiting assembly includes an upper movable plate and a lower movable plate, one side end portion of the upper movable plate and the lower movable plate are connected to the side wall of the air guide groove, and the other side end portion of the upper movable plate and the lower movable plate are also connected to an outer plate, the outer plate has a plurality of liquid outlet holes, and the inner side of the liquid outlet hole is connected to a liquid guide hole.

[0012] Optionally, a connecting pipe connecting the upper and lower cavities of the limiting component is provided on the side of the limiting component close to the temperature difference heating unit, a heat expansion component is provided on the outside of the connecting pipe, and hot melt adhesive is provided between the heat expansion component and the outer plate.

[0013] Optionally, a diaphragm is provided on the outer side of the heat-expandable component, a connecting rod is connected to the diaphragm, and an arc-shaped piece is hinged at the end of the connecting rod.

[0014] In the present invention, by placing a hand on the handle to pull the movable drawer, the movable drawer drives the frying basket to move, drives the piston to move to the right, squeezes the nitrogen in the compression cylinder, and allows the gas heated by high temperature to enter the heat exchange cylinder. The temperature in the heat exchange cylinder rises, so that the hot melt adhesive between the heat expansion part and the outer plate is melted. When the heat expansion part is not heated and expanded, the arc-shaped sheet stretches and does not cover the liquid outlet hole and the liquid guide hole. At the same time, the heat expansion part is heated and expanded, pushing the connecting rod to move to the left, pushing the arc-shaped sheet to cover the liquid outlet hole and the liquid guide hole to prevent excessive liquid hot melt adhesive from being lost. In particular, the hot melt adhesive in the liquid outlet hole and the liquid guide hole is melted, thereby allowing the limit assembly to move along the slide groove.

[0015] As the air pressure under the piston increases, the piston is pushed upward, and the first rack drives the gear to rotate. On the one hand, the guide plate moves upward, so that the airflow can enter the air outlet cylinder through the heat exchange cylinder; at the same time, the gear drives the second rack to move downward, driving the slide to move downward; the air guide cylinder is connected to the cavities above and below the piston through the connecting pipe, so that the gas can enter the top of the piston from the bottom of the piston, and finally flow back to the supporting compression cylinder. In this process, the high-temperature gas acts on one side of the temperature difference heating unit, causing the temperature difference heating unit to heat up. At the same time, only when the gas reaches a predetermined size and the temperature rises to a certain temperature, will the gas above and below the piston be connected, and efficient heat exchange will occur, thereby achieving the effect of automatically controlling the temperature difference heating unit to generate current.

[0016] Beneficial Effects

[0017] 1.

On the one hand, the guide plate moves upward, so that the airflow can enter the air outlet cylinder through the heat exchange cylinder; at the same time, the gear drives the second rack to move downward, driving the slide to move downward; the air guide cylinder is connected to the cavities above and below the piston through the connecting pipe, so that the gas can enter the top of the piston from the bottom of the piston, and finally flow back to the supporting compression cylinder. In this process, the high-temperature gas acts on one side of the temperature difference heating unit, causing the temperature difference heating unit to heat up. At the same time, only when the gas reaches a predetermined size and the temperature rises to a certain temperature, will the gas above and below the piston be connected, and efficient heat exchange will occur, thereby achieving the effect of automatically controlling the temperature difference heating unit to generate current.
