Preferably, the inner wall of the movable frame is fixedly provided with uniformly distributed fixing strips.
Preferably, the outlet end of the induced draft fan is connected with one end of a second connecting pipe, and the other end of the second connecting pipe is communicated with the first connecting pipe through a three-way joint.
Preferably, the first connecting pipe and the second connecting pipe are both rubber hoses, and the electromagnetic valves are mounted on the first connecting pipe and the second connecting pipe.
The utility model has the advantages that:
1. when the device is used, clean air is provided for the inside of the vending machine through the draught fan and the filter plate, and when the draught fan works, the gas inside the sucker can be discharged, so that the sucker is tightly attached to the movable frame, and the movable frame is not easy to fall off.
2. When the device is used, the electromagnetic valve on the first connecting pipe is closed when the filter plate needs to be cleaned or replaced, so that the air pressure inside the sucker becomes high, the friction force between the sucker and the movable frame becomes small, the movable frame can be conveniently taken down at the moment, and then the filter plate is operated.

In the figure: the device comprises a fixed frame 1, a movable frame 2, a fixed strip 3, a filter plate 4, a fixed block 5, an induced draft cover 6, an induced draft fan 7, a first connecting pipe 8, a sucking disc 9 and a second connecting pipe 10.
Detailed Description
The technical solutions in the embodiments of the present invention will be described clearly and completely with reference to the accompanying drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only some embodiments of the present invention, not all embodiments.
Referring to fig. 1-3, a ventilation structure of an unmanned vending machine based on the internet of things comprises a fixed frame 1, wherein a movable frame 2, a filter plate 4 and a fixed block 5 are sequentially arranged inside the fixed frame 1 along the horizontal direction, the fixed block 5 is fixedly connected with the inner wall of the fixed frame 1, the movable frame 2 and the filter plate 4 are in contact with the inner wall of the fixed frame 1, an induced draft cover 6 is fixedly arranged at one end of the fixed frame 1 close to the fixed block 5, an opening of the induced draft cover 6 is communicated with the fixed frame 1, an outlet of the induced draft cover 6 is communicated with an inlet end of an induced draft fan 7, the inlet end of the induced draft fan 7 is also connected with one end of a first connecting pipe 8, the diameter of the inlet end of the induced draft fan 7 is 5-10 times that of the first connecting pipe 8, the other end of the first connecting pipe 8, and the opening of the suction cup 9 is contacted with the movable frame 2.
Further, fixed mounting has evenly distributed's fixed strip 3 on the inner wall of movable frame 2, fixed strip 3 and movable frame 2 welded connection.
Further, the pipe wall of the outlet end of the induced draft fan 7 is connected with one end of a second connecting pipe 10, the diameter of the outlet end of the induced draft fan 7 is 5 times to 10 times of the diameter of the second connecting pipe 10, the other end of the second connecting pipe 10 is communicated with the first connecting pipe 8 through a three-way joint, and the outlet end of the induced draft fan 7 is communicated with the inside of the unmanned vending machine.
