[0026] The present invention provides a sterilizing cabinet heat energy circulation device through improvement, and its working principle is as follows;

[0027] First, the device is placed at a designated location and connected to an external controller. Then, the object to be heated and sterilized is placed inside the sterilization cabinet 3 and the cabinet door 4 is closed.

[0028] Second, the fan 8 and the heater 9 can be started by an external controller, so that the fan 8 and the heater 9 cooperate to generate hot air, and the hot air passes through the circulation hole 1 and enters the inner side of the sterilizing cabinet 3 to heat and sterilize the objects, and the hot air passes through the inner side of the sterilizing cabinet 3 and enters the circulation channel 6, and then passes through the ventilation hole 10, the air guide cover 7 and the circulation hole 1 from the circulation channel 6 and continues to enter the inner side of the sterilizing cabinet 3 for circulation;

[0029] Third, when the articles are sterilized, the heater 8 can be turned off, and at the same time, external water is introduced into the inner side of the heat conduction box 51 through the water inlet pipe 52, and the cold water passes through the square holes on the top of the heat expansion plate 55 and the foam plate 54 and enters the inner bottom of the heat conduction box 51. When a certain amount of cold water accumulates at the inner bottom of the heat conduction box 51, a thrust is applied to the foam plate 54 to push the foam plate 54, the heat expansion plate 55 and the plug 59 upward to enter the inner side of the through hole 510. At this time, a large amount of hot air in the circulation channel 6 is guided by the fan 8 to contact the outer surface of the heat conduction box 51, and the heat conduction box 51 introduces heat to the cold water inside to improve the stability of the cold water for use, and the heat expansion plate 55 is difficult to be closely attached to the inner top surface of the heat conduction box 51 under the action of the guide limit frame 57. At this time, the gas temperature in the circulation channel 6 is reduced, which facilitates the stability of the outer surface of the article, and the cold water is filtered by the filter plate 561, the filter 564 and the activated carbon layer 565 in the process of entering the heat conduction box 51;

[0030] Fourthly, when the water in the heat transfer box 51 continues to heat up, the heat expansion plate 55 expands due to the heat and continues to push the plug 59 to move upward, and the plug 59 drives the top sensing metal sheet to move upward and enter the sensing area of ​​the proximity switch 513, so that the proximity switch 513 opens the first solenoid valve 53 and discharges the hot water in the heat transfer box 51 to the outside through the drain pipe 52.

[0031] The present invention provides a heat energy circulation device for a sterilizing cabinet through improvement, wherein external water is introduced into the inner side of a heat conducting box 51 through a water inlet pipe 52, and cold water enters the inner bottom end of the heat conducting box 51 after passing through the square holes on the top of the heat expansion plate 55 and the foam plate 54. When a certain amount of cold water accumulates at the inner bottom end of the heat conducting box 51, a thrust is applied to the foam plate 54 to push the foam plate 54, the heat expansion plate 55 and the plug 59 upward to enter the inner side of the through hole 510. At this time, a large amount of hot air in the circulation channel 6 is guided by the fan 8 to contact the outer surface of the heat conducting box 51, and the heat conducting box 51 introduces heat into the cold water inside to improve the stability of the cold water for use, and the heat expansion plate 55 is on the guide limit frame 57. Under the action of, it is difficult to stick to the inner top surface of the heat transfer box 51. At this time, the gas temperature in the circulation channel 6 is reduced, which makes it easier to stabilize the outer surface of the article and make it lower. In the process of entering the heat transfer box 51, the cold water is filtered by the filter plate 561, the filter 564 and the activated carbon layer 565, so as to quickly absorb and cool the hot air in the circulation channel 6, and at the same time recycle the hot air to reduce the waste of resources. Square holes are opened on the top surfaces of the foam plate 54 and the heat expansion plate 55, and the square holes are symmetrically arranged at two ends on the left and right sides of the top of the foam plate 54 and the heat expansion plate 55, so that the cold water can enter the inner bottom end of the heat transfer box 51 through the square holes.
