[0022] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0023] Please see Figure 1 , Figure 2 , Figure 3 , Figure 4 , Figure 5A drying oven for vacuum electronic device processing includes a box body 1, a box cover 2 on the front of the box body 1, a pressure relief pipe 4 fixedly connected to the inner wall of the box body 1, a threaded head 6 connected to the inner wall of the pressure relief pipe 4 by a thread, a heat-resistant spring 7 contacting the left end of the threaded head 6, a plug 8 fixedly connected to the left end of the heat-resistant spring 7, the plug 8 being slidably connected to the pressure relief pipe 4, and a limit rod 9 fixedly connected to the inner wall of the pressure relief pipe 4, the limit rod 9 contacting the plug 8.

[0024] Please see Figure 1 , Figure 2 , Figure 3 , Figure 4 Two heaters 3 are fixedly installed on the inner wall of the housing 1. The two heaters 3 are symmetrically distributed on the housing 1. The heaters 3 can heat the vacuum electronic devices inside the basket 112. Two pressure relief grooves 5 are opened on the surface of the pressure relief pipe 4. The two pressure relief grooves 5 are symmetrically distributed on the pressure relief pipe 4. The pressure relief grooves 5 can be used to relieve pressure on the housing 1. A guide plate 10 is slidably connected to the inner wall of the limiting rod 9. The guide plate 10 is fixedly connected to the plug 8. The guide plate 10 can guide the movement of the plug 8 to ensure the stability of the movement of the plug 8.

[0025] Please see Figure 1 , Figure 2 , Figure 3 , Figure 5 The housing 1 is equipped with a rotating mechanism 11, which includes a motor 111. The motor 111 is fixedly installed in the middle of the upper end of the housing 1. The output shaft of the motor 111 is rotatably connected to the housing 1. A placement basket 112 is fixedly sleeved on the outside of the output shaft of the motor 111. A rotating disk 113 is fixedly connected to the output shaft of the motor 111. The rotating disk 113 is rotatably connected to the bottom inner side of the housing 1. An annular groove 115 is provided on the side of the rotating disk 113. A telescopic plate 116 is slidably connected to the inner wall of the housing 1. A limit ball 117 is fixedly connected to the horizontal part of the telescopic plate 116. The limit ball 117 is slidably connected to the annular groove 115. Through the action of the motor 111, the placement basket 112 and other structures, the vacuum electronic device can be driven to rotate, thereby improving the heating effect of the vacuum electronic device. Under the structure of the rotating disk 113, the limit ball 117 and other structures, the excessively long output shaft of the motor 111 can be rotated and guided, avoiding the problem of slight vibration of the output shaft.

[0026] Please see Figure 1 , Figure 2 , Figure 3 , Figure 5Two limiting plates 114 are fixedly connected to the inner side wall of the housing 1. The vertical part of each limiting plate 114 is slidably connected to the rotating disk 113. Through the action of the limiting plate 114, the rotating disk 113 can be rotated and limited. A heat-resistant elastic sheet 118 is welded to the vertical part of the telescopic plate 116. The other end of the heat-resistant elastic sheet 118 is welded to the housing 1. Through the setting of the heat-resistant elastic sheet 118, the telescopic plate 116 can be connected and used.

[0027] The specific implementation process of this utility model is as follows: In use, the motor 111 is started to drive the output shaft to move, thereby driving the placement basket 112 to rotate, so that the vacuum electronic device rotates. With the help of the heater 3, the vacuum electronic device can be uniformly heated, improving the efficiency of heating and drying. When the motor 111 drives the output shaft to rotate, it can drive the rotating disk 113 to rotate, so that the limiting plate 114 slides along the surface of the rotating disk 113 and the limiting ball 117 slides along the inner wall of the annular groove 115 to limit the rotation of the rotating disk 113. Under the deformation of the heat-resistant elastic sheet 118, the telescopic plate 116 can be pushed to drive the limiting ball 117 to always contact the annular groove 115 to ensure a good limiting effect and avoid the problem of centrifugal vibration caused by the excessively long output shaft of the motor 111.

[0028] Under the continuous heating action of heater 3, the air inside the box 1 gradually heats up and pressurizes. When the pressure difference inside the pressure relief pipe 4 is too large, the gas inside the box 1 impacts the plug 8 and moves to the right, so as to drive the guide plate 10 to slide along the inner wall of the limit rod 9, thereby ensuring the stable movement of the plug 8. Under the action of the threaded head 6, the heat-resistant spring 7 deforms, causing the plug 8 to slide along the inner wall of the pressure relief pipe 4, and finally the pressure relief groove 5 is in a flow state, so as to automatically relieve the pressure of the box 1 and avoid the problem of high pressure damage to the box 1.

[0029] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
