It should be understood that the following text is merely used to describe one or more specific implementations of this utility model and does not strictly limit the scope of protection specifically claimed by this utility model.

[0022] like Figure 1-4 As shown, a ventilation system for a food packaging workshop includes a ventilation duct 1 and a mounting plate 11 disposed outside the ventilation duct 1. A humidity sensor 4 is installed on the lower surface of the ventilation duct 1, and a control box 3 is disposed on the outer side of the ventilation duct 1. A humidification box 2 is installed on the upper surface of the ventilation duct 1. A drain pipe 25 is connected to the lower surface of the humidification box 2 inside a connecting pipe 21. The lower end of the drain pipe 25 is connected to the connecting pipe 21. Spray nozzles 22 are symmetrically arranged on the lower surface of the connecting pipe 21. An exhaust fan is also disposed inside the ventilation duct 1. 6. A positioning groove 12 is provided on the outside of the ventilation pipe 1. A box plate 5 is snapped into the inside of the positioning groove 12. Two sets of filter screens 52 are provided on one side of the box plate 5. A handle 51 is provided on the outside of the box plate 5. This device uses a humidity sensor 4 to monitor the humidity in the food packaging workshop. When the humidity is low, the liquid pump 24 can be controlled by the controller inside the control box 3 to extract water. After extraction, the water is sprayed out through the nozzle 22 and enters the food packaging workshop with the exhaust fan 6 to achieve the purpose of humidification.

[0023] like Figure 4 As shown, the humidifier 2 is equipped with a liquid pump 24 inside. The liquid outlet of the liquid pump 24 is connected to one end of the drain pipe 25. The upper surface of the humidifier 2 is also equipped with a liquid inlet pipe 23. The upper end of the liquid inlet pipe 23 is threaded with a sealing cap. This setup utilizes the liquid pump 24 inside the humidifier 2 to draw water from inside the humidifier 2 and enter the connecting pipe 21 through the drain pipe 25. Finally, the water is sprayed out through the nozzle 22 and sent into the food packaging workshop by the drawn air to humidify the interior of the workshop.

[0024] like Figure 1 As shown, the control box 3 is also equipped with a controller and a wireless transmission module. The controller is connected to the humidity sensor 4, and the wireless transmission module is connected to an external device. This setup allows the controller inside the control box 3 to control the operation of the liquid pump 24, and the wireless transmission module to control it through the external device. The controller, wireless transmission module, humidity sensor 4, and liquid pump 24 inside the control box 3 are all existing known electrical devices, and all can be purchased and used directly on the market. Their structure, circuit, and control principle are all existing known technologies. Therefore, the structure, circuit, and control principle of the device will not be described in detail here.

[0025] like Figure 2 and Figure 3As shown, a positioning pin 53 is symmetrically arranged on one side of the box plate 5, and a positioning hole that engages with the positioning pin 53 is opened on one side of the positioning groove 12. A frame 54 is symmetrically arranged on one side of the box plate 5, and the filter screen 52 is slidably installed inside the frame 54. This arrangement utilizes the filter screen 52 to slide inside the frame 54 and connect it with screws. At the same time, the positioning pin 53 is embedded in the positioning hole to ensure the stability of the connection and facilitate its disassembly to achieve the purpose of replacing and cleaning the filter screen 52.

[0026] The working principle of this utility model is as follows: When using the ventilation system of this utility model for a food packaging workshop, the ventilation pipe 1 is first installed on the top of the food packaging workshop via the mounting plate 11. The front half of the ventilation pipe 1 is located inside the food packaging workshop, while the rear half is located outside. All electrical components used in this utility model are connected to an external controller and power supply. During ventilation, the exhaust fan 6 inside the ventilation pipe 1 is activated to allow outside air to enter the food packaging workshop through the ventilation pipe 1, thus achieving ventilation. A humidity sensor 4 is installed on the lower surface of the ventilation pipe 1, which can be used to monitor the temperature and humidity inside the food packaging workshop. The controller can control the pump 24 to extract water from its interior and send it through the drain pipe 25 into the connecting pipe 21. Finally, the water is sprayed out through the nozzle 22 to achieve humidification, thereby increasing the humidity in the food packaging workshop and improving the comfort of personnel. At the same time, when external air enters the ventilation pipe 1, it will be filtered by two sets of filters 52 to prevent external dust from entering the food packaging workshop. When it is necessary to remove and clean the filters 52, the handle 51 can be held to pull the box panel 5 to one side to pull out the filters 52. After being pulled out, the filters 52 and the frame 54 can be disassembled for cleaning. It is practical.
