[0025] Embodiment 1:

[0026] Please refer to Figures 1 to 6 Figures 1 to 6 , a dry heat sterilization cabinet with temperature monitoring of the present utility model, includes a sterilization cabinet 1. A cabinet door 2 is hingedly installed at the front end on the left side inside the sterilization cabinet 1, and the left side inside the sterilization cabinet 1 is slidably connected to the left side of a tray 5.

[0027] A heating device 3 is arranged at the top of the sterilization cabinet 1, and distance adjustment devices 4 are arranged on both the left and right sides of the inner wall of the sterilization cabinet 1. The heating device 3 includes a heating box 31 bolted to the top of the sterilization cabinet 1. The heating box 31 provides a platform for installing other components. A first temperature sensor 32 is arranged at the right end of the top of the heating box 31. The arranged first temperature sensor 32 detects and controls the heating temperature of a resistance heating plate 37. An air pump 33 is bolted to the left side of the heating box 31;

[0028] The right side of the heating box 31 is connected to a solenoid valve 34 installed on the right side of the sterilization cabinet 1 through a conduit. A pressure filter layer 35 is arranged at the left end of the inner bottom of the heating box 31. The pressure filter layer 35 filters out the impurities inside. A sterilization layer 36 is installed at the middle end of the inner bottom of the heating box 31 through screws. A resistance heating plate 37 is bolted to the right end of the inner bottom of the heating box 31. A second temperature sensor 38 is fixed to the left side of the sterilization cabinet 1 through screws. Baffles are symmetrically arranged at the right end of the inner top and inner bottom of the heating box 31. When the air flow contacts the baffles, collisions will occur, thereby making the air flow reverse and converge to improve the heating effect.

[0029] The working principle of a dry heat sterilization cabinet with temperature monitoring based on Embodiment 1 is as follows:

[0030] First, when using this device, first place this device in the working area, and then connect the device to an external power supply to provide the power required for the operation of this device;

[0031] Second, before sterilizing workpieces or materials, start the air pump 33 and the resistance heating plate 37 through the control terminal. The air pump 33 pumps air into the heating box 31. When the air enters the inside of the heating box 31, it first passes through the pressure filter layer 35 to filter out the impurities inside, and then passes through the sterilization layer 36 for sterilization treatment;

[0032] Third, then the resistance heating plate 37 heats the passing air flow. When the air flow contacts the baffles, collisions will occur, thereby making the air flow reverse and converge to improve the heating effect. Then the control terminal controls to open a solenoid valve 34 to make the hot air flow enter the sterilization cabinet 1; and the arranged first temperature sensor 32 detects and controls the heating temperature of the resistance heating plate 37. When the second temperature sensor 38 detects a large temperature difference inside the sterilization cabinet 1, the control terminal controls to open the remaining solenoid valves 34, thereby avoiding large temperature difference changes inside the sterilization cabinet 1;

[0033] Fourthly, the workpieces or materials on the tray 5 are sterilized, which helps to fully filter and sterilize the pumped air, avoid air pollution of the workpieces or materials, and the heating temperature can be accurately detected and controlled by the first temperature sensor 32. Moreover, the baffle causes the air flow to intersect reversely, thereby improving the heating efficiency and heating effect of the air flow. And under the cooperation of the second temperature sensor 38, the temperature difference inside the sterilization cabinet 1 is monitored and adjusted.

[0034] Embodiment 2:
