Technical Field
[0001] This utility model relates to the field of intelligent laboratory disinfection equipment technology, specifically to a cargo disinfection channel that integrates multi-dimensional sensing technology and can adaptively adjust spray parameters. Background Technology
[0002] In biosafety laboratories, cold chain logistics, and other scenarios, disinfection of cargo surfaces is a key step in preventing contamination by pathogenic microorganisms.
[0003] Traditional disinfection tunnels primarily employ ultrasonic atomization technology, spraying disinfectant as a mist into a designated space to achieve disinfection. However, when disinfecting goods, these tunnels cannot determine whether goods are within the designated area, nor can they assess their weight or size, resulting in blind spots in disinfection. Furthermore, the disinfection process is poorly controlled, leading to waste of disinfectant and insufficient penetration.
[0004] To address this, a cargo disinfection channel with cargo sensing function was designed. The sensing function determines whether the cargo is in the designated area. By calculating the cargo volume, different disinfection times and disinfectant release amounts are set to achieve comprehensive disinfection of the cargo. Utility Model Content

This utility model has the advantage of achieving comprehensive and effective disinfection according to the condition of the cargo.
[0006] This utility model provides a cargo disinfection channel with cargo sensing function, comprising a channel and disinfection spray pipes. Vertically distributed disinfection spray pipes are slidably connected to both sides of the channel. A row of vertically distributed infrared sensors and nozzles are arranged on opposite sides of the disinfection spray pipes on both sides of the channel. The first infrared sensor is located on one side of the nozzle. A second infrared sensor is located in the lower middle part of the inner side of the channel. A controller, an atomizer, and a control valve assembly are located on the outer side of the channel. The atomizer delivers disinfection spray through the control valve assembly and nozzles. A control assembly for controlling the forward and backward movement of the disinfection spray pipes is located at the top of the channel.
[0007] Furthermore, the channel is a box structure with a rectangular cross-section. The two ends of the channel are connected to gates. The top of the channel is equipped with a control cylinder, the output shaft of which is fixedly connected to a connecting beam. The two ends of the connecting beam are fixedly connected to the top of the gates at both ends of the channel.
[0008] Furthermore, the control assembly includes a suspension frame, a drive shaft, and a control motor.

The control motor is fixedly installed on one side outside the chamber and its output shaft is fixedly connected to one end of the drive shaft.
[0009] Furthermore, the suspension frame includes a crossbeam and a connecting beam located at the bottom of the crossbeam. The two ends of the crossbeam are welded with sliders, and the top of the box channel is provided with a sliding groove that cooperates with the sliders.

[0021] To make the technical means, creative features, objectives and effects of this utility model easier to understand, the present utility model will be further described below in conjunction with specific embodiments.
[0022] Please see Figures 1 to 3 This utility model provides a technical solution: a cargo disinfection channel with cargo sensing function, including a channel 1 and a disinfection spray pipe 2. The channel 1 is the location for cargo disinfection. The channel 1 is a rectangular box structure. Gates 11 are slidably connected to both ends of the channel 1. A control cylinder 12 is installed at the top of the channel 1. The output shaft of the control cylinder 12 is fixedly connected to a connecting beam 121. The two ends of the connecting beam 121 are fixedly connected to the top of the gates 11 at both ends of the channel 1. When the gates 11 move downward to their extreme positions, both ends of the channel 1 are sealed, and the channel 1 is in a near-sealed state, thereby preventing the disinfection mist from leaking out and polluting the air. In use, the cargo is transported into the channel 1, the channel 1 is closed, and then the spray disinfection treatment is performed.
[0023] In addition, both sides of the passageway 1 are equipped with back-and-forth sliding disinfection spray pipes 2. These spray pipes can spray disinfection on both sides of the goods as they move back and forth, and are suitable for goods of different lengths. The disinfection spray pipes 2 are vertically distributed, which can fully cover and disinfect goods of different heights.
[0024] In this technical solution, a row of vertically distributed infrared sensors 3 and nozzles 4 are installed on opposite sides of the disinfection spray pipes 2 on both sides of the passageway 1. The infrared sensors 3 are located to one side of each nozzle 4; that is, one nozzle 4 corresponds to one infrared sensor 3. These infrared sensors 3 adopt a standard combined structure, including an infrared transmitter and an infrared receiver. During use, the infrared transmitter and receiver are respectively installed on opposite sides of the disinfection spray pipes 2 on both sides of the passageway 1. The function of the infrared sensors 3 is to sense the volume of the goods, thereby controlling the travel distance of the disinfection spray pipe 2 and the number of nozzles 4 that open.
[0025] Infrared sensor 25 is located near the bottom of the inner side of the passageway 1. Infrared sensor 25 has the same structure as infrared sensor 3 and is used to detect whether goods have entered the disinfection area. When goods enter the disinfection area, infrared sensor 25 senses the movement and generates a corresponding trigger signal. Furthermore, a controller 6 is located on the outer side of passageway 1. This controller 6 has a built-in control circuit board, which is electrically connected to infrared sensors 3 and 25. The control circuit board integrates a microcontroller to analyze and process the sensing signals from infrared sensors 3 and 25, and converts them into control signals to be sent to the actuators.
[0026] Specifically, an atomizer 7 and a control valve assembly 8 are installed on the outside of the enclosure 1, both electrically connected to the controller 6. The control signals issued by the controller 6 control the opening and closing of the atomizer 7 and the control valve assembly 8. The atomizer 7 delivers disinfectant spray to the nozzles 4 through the control valve assembly 8. The control valve assembly 8 consists of multiple solenoid valves, each corresponding to one nozzle 4. In use, a conduit 15 is fixedly connected to the top of the enclosure 1. The conduit 15 is used to transmit spray from the atomizer 7 to the control valve assembly 8 through the hoses connecting the solenoid valves and nozzles and related wiring. The control valve assembly 8 then transmits spray to each nozzle 4. The top of the enclosure 1 is equipped with a control assembly 9 that controls the forward and backward movement of the disinfectant spray tube 2. Its control part is electrically connected to the controller 6, meaning that the movement of the disinfectant spray tube 2 is controlled based on the information detected by the infrared sensor 3.
[0027] Furthermore, the control assembly 9 includes a suspension bracket 91, a drive shaft 92, and a control motor 93. The suspension bracket 91 is slidably connected to the top of the housing 1 and fixedly connected to the disinfection spray pipe 2. The drive shaft 92 is rotatably connected to the top of the housing 1, and a drive gear 921 is fixedly sleeved on it. The drive gear 921 meshes with the suspension bracket 91. The control motor 93 is fixedly installed on one side outside the housing 1, and its output shaft is fixedly connected to one end of the drive shaft 92. The control motor 93 is electrically connected to the controller 6 to provide driving force for the rotation of the drive shaft 92. When the drive shaft 92 rotates, it drives the suspension bracket 91 to move by meshing.
[0028] Specifically, the suspension frame 91 consists of a crossbeam 911 and a connecting beam 912 located at the bottom of the crossbeam 911. In use, the crossbeam 911 can be designed with a rack structure that meshes with the transmission gear 921. Slider blocks 9111 are welded to both ends of the crossbeam 911. A groove 13 is provided at the top of the housing 1 to slide and engage with the sliders 9111. Both ends of the connecting beam 912 are fixedly connected to the top of the adjacent disinfectant spray pipes 2. It should be noted that the height of the infrared sensor 25 is lower than the bottom of the disinfectant spray pipe 2.
[0029] In this embodiment, an exhaust pipe 14 is provided at the top of the chamber 1, and an exhaust fan 141 is installed inside the exhaust pipe 14. In use, the exhaust pipe 14 is connected to an external waste gas treatment pipeline through a pipe. After the exhaust fan 141 is started, it can discharge the disinfectant mist inside the chamber 1. An air filter assembly 142 is provided inside the exhaust pipe 14, located upstream of the exhaust fan 141. The function of the air filter assembly 142 is to purify the excess disinfectant mist discharged from the chamber 1, achieving safe emission. In use, the air filter assembly 142 can be a filter composed of a HEPA filter and activated carbon material. A breathing filter disc can be installed on one side of the chamber 1. When the exhaust fan 141 is started, external air enters the chamber 1 through the filter disc to replenish the gas. The material of the filter disc is the same as that of the air filter assembly 142.
[0030] In this embodiment, a conveyor belt 101 with weighing function is provided at the bottom of the box 1. The electronic scale part on the conveyor belt 101 is electrically connected to the controller 6 to transmit the measured weight data of the goods to the controller 6. The controller 6 adjusts the spraying time according to the weight data of the goods.
[0031] Working principle: Before use, the controller 6 is electrically connected to the control cylinder 12, conveyor belt 101, and exhaust fan 141 involved in this application. During use, the controller 6 is activated by pressing a button on its button area, which starts the control cylinder 12, opening the gate 11. The goods are then placed on the conveyor belt 101, which moves the goods inward. When the goods block the infrared rays emitted by the infrared sensor 5, it indicates that the goods have reached the disinfection spray area. At this time, the conveyor belt 101 stops running, and the control gate 11 closes. Subsequently, the controller 6 activates the control motor 93, causing the suspension frame 91 to move the disinfection spray pipe 2 upstream. When infrared sensor 3 detects goods, the corresponding nozzle 4 turns on and sprays disinfectant. The disinfectant spray pipe 2 moves upstream until infrared sensor 3 can no longer detect the goods. At this point, controller 6 controls motor 93 to reverse, causing the disinfectant spray pipe 2 to move in the opposite direction, completing two cycles (as needed) to achieve comprehensive disinfection. After disinfection, exhaust fan 141 starts to discharge the disinfectant mist. Then, control gate 11 opens, and conveyor belt 101 starts to transport the disinfected goods to one end of the conveyor belt 1, where operators can remove them using sterile gloves. Finally, control gate 11 opens, and conveyor belt 101 starts to move the disinfected goods to the near end of the conveyor belt 1, where operators can remove them using sterile gloves.
[0032] Furthermore, it should be understood that although this specification describes different implementation methods, it does not mean that each implementation method contains only a single technical solution. This narrative style is intended to clearly express that those skilled in the art should regard the specification as a whole. The technical solutions in each embodiment can also be appropriately combined to form other implementation methods that can be understood by those skilled in the art.
