[0021] like Figure 1 and Figure 2 As shown, an observation window of a flue-cured tobacco intensive curing room includes a movable metal plate 1, which is hinged to a door frame 11 by a hinge 5, an observation window 2 is arranged on the upper half of the movable metal plate 1, a defogger and heater is arranged on the back of the movable metal plate 1, a snap device is arranged on the bottom of the movable metal plate 1, and a handle 3 is arranged on the front of the movable metal plate 1; during use, an observer can quickly flip the movable metal plate 1 through the handle 3 to form an opening and closing, the defogger and heater can adjust the internal and external temperatures of the observation window 2 and prevent the formation of water vapor, and the snap device can not only limit the movable metal plate 1, but also have the effect of turning on the power supply.
[0022] The preferred solution is Figure 1 As shown, a display box 14 is provided on the front of the movable metal plate 1, and a slot is opened at the upper end of the display box 14; the display box 14 is made of transparent material, and a high-definition picture of the baking process flow curve is drawn and inserted into the slot and displayed in the display box 14, so that the observer can identify the changing characteristics of the leaves during the baking process, thereby accurately comparing them with the real objects, and then adjusting the temperature and humidity according to the corresponding yellowing degree.
[0023] The preferred solution is Figure 2 As shown, the demisting heating device includes a heater 6, which is installed on the back of the movable metal plate 1. The lower half of the movable metal plate 1 is a hollow structure. A plurality of hot air ports 4 are equidistantly arranged on the back of the movable metal plate 1, and the hot air ports 4 are connected to the heater 6.
[0024] When the observation window 2 needs to be defogged, the heater 6 is started and heats the air inside the movable metal plate 1. The hot air flows out through the hot air outlet 4 and bakes and heats the observation window 2, making the internal and external temperatures of the observation window 2 consistent and preventing water vapor condensation.
[0025] The preferred solution is Figure 3 and Figure 4 As shown, the buckle device includes a metal contact 8 and a card slot 12. The metal contact 8 is installed in the bottom mounting slot 10 of the movable metal plate 1 through a conductive spring 9, and the other end of the conductive spring 9 is connected to the heater 6 through a wire; the card slot 12 is installed at the bottom of the door frame 11 and corresponds to the position of the metal contact 8, and a contact head 13 is correspondingly arranged in the card slot 12; a power box 7 is arranged on the back of the door frame 11, and the power box 7 is connected to the contact head 13 through a wire;
[0026] When the movable metal plate 1 is closed, the metal contact 8 will compress the conductive spring 9 and be clamped in the card slot 12. At this time, the metal contact 8 is in contact with the contact head 13 and is conductive. Since the other end of the metal contact 8 is connected to the heater 6 through the conductive spring 9 and the wire, and the other end of the contact head 13 is connected to the power box 7 through the wire, the power box 7 and the heater 6 are in an electrically conductive state. The observer can start the heater 6 at any time and defog the observation window 2. When the movable metal plate 1 is in the open state, the heater 6 is immediately disconnected from the power box 7, and the heater 6 immediately stops working to reduce energy waste.
