Nowadays, they have been widely used in industries such as chemical industry, electronic communication, plastics, cables, electroplating, hardware, automobiles, optoelectronics, rubber products, molds, spraying, printing, medical treatment, aerospace and colleges and universities. The huge market demand has led to the diversification of drying ovens, and the structural quality of the products is also different. Therefore, an electric heating constant temperature drying oven with exhaust gas drainage function is needed.

[0003] According to the description of an electric constant temperature drying oven disclosed on the patent website (authorization announcement number: CN 218380300 U), "The utility model provides an electric constant temperature drying oven, including: a drying oven; a fixed plate, the fixed plate is fixedly installed at the bottom of the inner side of the drying oven, one side of the fixed plate is rotatably connected to a screw rod, one end of the screw rod is fixedly installed with a drive motor, the drive motor is fixedly installed on the back of the drying oven, and the output end of the drive motor passes through the back of the drying oven and extends to the inner side; a threaded sleeve, the threaded sleeve is threadedly connected to the outer side of the screw rod, the outer side of the threaded sleeve is fixedly installed with a fixed block, and the top of the fixed block is fixedly installed with a fixed frame. The electric constant temperature drying oven provided by the utility model can push the tray out from the inner side of the drying oven when in use through the drive motor, screw rod, threaded sleeve and fixed frame, so that the user can remove the tray conveniently and avoid scalding the user's hands when removing the tray inside the drying oven."

[0004] In response to the above description, the applicant believes that the following problems exist: when the device is in use, the drive motor is turned on, and the rotation of the drive motor drives the screw to rotate, so that it is threadedly connected to the inner side of the threaded sleeve, driving the threaded sleeve to move. At this time, the movement of the threaded sleeve drives the fixed frame to move, so that the fixed frame moves from the inner side of the drying box to the outside.
