[0029] Furthermore, a heat-insulating layer 10 is laid on the outer side of the door 4 , which has a heat-insulating effect and prevents heat loss in the working room 2 .

[0030] Furthermore, a moving mechanism 11 is symmetrically installed at the bottom of both sides of the main box 1, and the moving mechanism 11 includes a support leg 110, a receiving groove 111 is opened at the bottom of the support leg 110, and a lifting groove 112 connected to the receiving groove 111 is opened on both sides of the support leg 110; a lifting plate 113 is movably provided in the receiving groove 111, and a moving wheel 114 is fixedly installed at the bottom of the lifting plate 113, and both sides of the lifting plate 113 extend through the lifting groove 112 and penetrate a screw rod 115, the bottom end of the screw rod 115 is fixedly connected to a rotating button 116, and the top end of the screw rod 115 is connected to the bottom of the main box 1.

[0031] Furthermore, the lifting plate 113 is provided with a through hole 12 for the screw rod 115 to pass through, and the through hole 12 is provided with an internal thread matching the thread of the screw rod 115 .

[0033] Further, a threaded hole 13 for connecting with the lead screw 115 is provided at the bottom of the main box 1.

[0037] Working principle: For a safe, interference-free and explosion-proof precision oven provided by the present invention, during use, the temperature in the door panel circulation air duct 5, the top circulation air duct 61, the bottom circulation air duct 62, the back circulation air duct 63, the left circulation air duct 64 and the right circulation air duct 65 is set through the intelligent temperature controller 3, and heating is carried out through the heating tube 7. Through the action of the motor 9 and the centrifugal impeller 8, hot air can be filled in each respective circulation air duct. The temperature sensor 14 is used to detect the temperature in the air duct where it is located and transmit it to the intelligent temperature controller 3. When the set value is reached, the intelligent temperature controller 3 controls the heating tube 7 in the corresponding air duct to be turned off. For those that do not reach the set value, heating continues. The door panel circulation air duct 5, the top circulation air duct 61, the bottom circulation air duct 62, the back circulation air duct 63, the left circulation air duct 64 and the right circulation air duct 65 all operate independently and have no interference with each other, ensuring that the temperature in the door panel circulation air duct 5, the top circulation air duct 61, the bottom circulation air duct 62, the back circulation air duct 63, the left circulation air duct 64 and the right circulation air duct 65 can be independently corrected, so that the temperature is the same on all six sides and around, thereby achieving a temperature uniformity without deviation. Moreover, there is no forced air circulation in the working chamber 2, and a temperature uniformity without deviation is also achieved. In addition, the working chamber 2 is completely isolated from the heating source and there is no forced air circulation, improving the safety of the oven during use; it is applicable to industries sensitive to temperature, such as flammable and explosive substances, electronic chips, military explosives, aerospace equipment sensors, etc.

[0038] Before heating, the box door 4 is closed, and the sealing frame 16 on the box door 4 is embedded into the sealing groove 17, which can improve the sealing performance of the main box 1, and further make it difficult for the working chamber 2 to be interfered by the electromagnetic field.

[0039] When the oven is moved, the screw rod 115 is rotated by rotating the knob 116, so that the screw rod 115 is pulled out from the threaded hole 13 at the bottom of the main box 1, and the lifting plate 113 can be released. Then, the lifting plate 113 is moved downward, and the lifting plate 113 drives the bottom moving wheel 114 to move downward, and the moving wheel 114 passes through the receiving groove 111 and is placed under the support leg 110. Then, the rotating knob 116 is rotated again to connect the screw rod 115 with the threaded hole 13, and the lifting plate 113 can be fixed. At this time, the oven can be moved, and the movement is convenient.

[0040] When fixing the oven, the screw rod 115 is driven to rotate by the rotating knob 116 to separate the screw rod 115 from the threaded hole 13. After separation, the lifting plate 113 is moved upward, and the lifting plate 113 drives the bottom moving wheel 114 to move upward. The moving wheel 114 is retracted into the accommodating groove 111, so that the support leg 110 contacts the table surface. Then, the rotating knob 116 is rotated again to connect the screw rod 115 with the threaded hole 13.

[0041] It is worth noting that the entire device is controlled by a main control button. Since the device matched with the control button is a common device and belongs to the existing mature technology, its electrical connection relationship and specific circuit structure will not be described in detail here.
