[0045] The following embodiments of the present invention are described in further detail with reference to the accompanying drawings and examples. The following examples are used to illustrate the present invention but are not intended to limit the scope of the present invention.

[0046] like Figure 1 As shown, this embodiment provides a sterilizer, which includes:

[0047] Rack 1000;

[0048] The conveying component 100 is mounted on the frame 1000 and is used to connect with the rotary turntable and can be connected to a trailer to transport objects from the trailer to the rotary turntable;

[0049] A disinfection chamber 200 is provided on the frame 1000 and is located above the conveying component 100. The disinfection chamber 200 and the conveying component 100 form a disinfection channel 201;

[0050] An ultrasonic atomization device 300 is in communication with the disinfection channel 201 and is used to output atomized disinfectant to the disinfection channel 201;

[0051] a detection device 400 , mounted on the disinfection chamber 200 , configured to output a signal when the object enters the disinfection passage 201 ; and

[0052] The controller is electrically connected to the conveying component 100, the ultrasonic atomizing device and the detecting device 400, and is used to control the ultrasonic atomizing device to output atomized disinfectant when receiving a signal from the detecting device 400.

[0053] The objects on the trailer are placed on the conveying component 100 and conveyed by the conveying component 100. When entering the disinfection cabin 200, the detection device 400 detects that the object has entered the disinfection channel 201, and then outputs a signal to the controller. The controller controls the ultrasonic atomization device 300 to spray disinfectant to disinfect the object according to the received signal. After passing through the disinfection channel 201, the object enters the rotary turntable under the conveyance of the conveying device and is conveyed to a designated position by the rotary turntable so that the passenger can obtain it. The disinfection machine of this embodiment can be used without It can be put into use immediately without modifying the existing equipment. It is required to fully adapt to the needs of the airport site environment. It can be used in locations where the space available for the disinfection machine is relatively small and the space for the disinfection machine is limited. It can also be directly connected for use, which is convenient and fast. The manual disinfection method is changed to an automatic machine disinfection method, replacing the manual disinfection method, and its efficiency has been effectively improved. At the same time, it can also carry out comprehensive disinfection of objects, thereby effectively solving the technical problems in the related technology of using manual disinfection, low disinfection efficiency, and inability to carry out comprehensive disinfection of luggage.

[0054] The disinfection machine of the present invention is embedded in the luggage arrival transfer line of the airport, playing a connecting role. It can be used as a transmission device in normal operation. It only needs to turn off the ultrasonic atomization device 300 to achieve it, or it can be turned on to achieve disinfection. It is installed at the location where the luggage is placed at the luggage placement of the turntable where the luggage arrives. In the past, this location was installed with a transfer conveyor belt, which is rarely used at present. When the luggage is transported from the aircraft cargo hold to the luggage arrival outfield, the luggage is manually moved to the entrance of the disinfection machine on the towed luggage truck. The staff starts the turntable and inputs the information of the arriving flight at the same time. The luggage retrieval information and flight information are displayed on the electronic signboard in the infield luggage arrival hall. After the disinfection machine of the turntable is started at the same time, the luggage is transported from the checked truck to the disinfection machine for disinfection, and then to the turntable for disinfection, and then to the turntable for cyclic transportation until all the luggage is retrieved by the passengers. The turntable automatically reminds the staff and automatically shuts down the conveyor after a delay.

[0055] The disinfection chamber 200 can be integrally formed or mounted on the frame 1000 by welding, bolts, screws, etc. The disinfection chamber 200 has a cavity inside, and the cavity and the conveying equipment form a disinfection channel 201, and the object passes through the disinfection channel 201.

[0056] The detection device 400 is an infrared trigger sensor installed at the entrance of the disinfection channel 201. When the object is detected, it sends a signal to the controller, which is preferably a single-chip microcomputer or a PLC controller;

[0057] In some embodiments, the conveying device may be a conveyor belt; in some embodiments, the conveying component 100 includes:

[0058] A plurality of transmission rollers 101 are rotatably mounted on the frame 1000 and arranged in an array, with slave transmission wheels provided at both ends;

[0059] A plurality of first belts 102, wherein the transmission wheels on two adjacent transmission rollers 101 transmit transmission to each other via the first belts 102;

[0060] The motor 103 is installed in the middle of the frame, and a main transmission wheel is provided on the main shaft;

[0061] The second belt 104 connects the motor 103 and the two transmission rollers 101 located on different first belts 102 .

[0062] The motor 103 drives the main transmission wheel to rotate, and the second belt 104 drives the transmission roller 101 to rotate, so that two of the transmission rollers 101 start to rotate. Since the two transmission rollers 101 are not on the same belt, the power of the two transmission rollers 101 can be transmitted to the transmission roller 101 connected to it through the first belt 102. Through this process, the power is continuously transmitted so that all the transmission rollers 101 can have the power to rotate. The object is placed on the transmission roller 101, and the object is passed through the disinfection chamber 200 by the power of the transmission roller 101 and is disinfected in the disinfection chamber 200 and then transported to the rotary turntable.

[0063] When the staff starts it, the transmission roller 101 runs automatically, and the default running speed is 0.3 meters per second. When the luggage is transported to the front door of the disinfection machine, the detection devices 400 on both sides detect the movement of the object, automatically start the ultrasonic spray device, and turn off the ultrasonic spray device after a delay of 3-5 seconds. When there is luggage that has been triggered, the automatic trigger will not be accumulated until the last luggage is transported and disinfected, and the ultrasonic spray device will be turned off. The detection devices 400 on both sides of the rear door are used to count the number of luggage. At the same time, the detection devices 400 serve as a switch for delaying the shutdown of the conveyor. When no new luggage arrives for disinfection within 10 minutes after the luggage is transported, the equipment automatically protects and shuts down the transmission roller 101. Of course, the conveyor can also be manually turned off to end the work.

[0064] Due to site limitations, the sterilizer also puts forward more compact requirements for the conveying component 100 of the stainless steel drive roller 101 configured for itself. It not only needs to be able to run for a long time, but also requires less noise, smaller size, and corrosion resistance. The sterilizer is based on the drive rollers 101 on both sides of the first belt 102, and is designed taking into account the need for extension from the drive wheel. At the same time, considering the narrow space factor, the drive roller 101 and the frame 1000 are structured in one. This design is not only convenient and space-saving, more compact and does not take up space, but also makes full use of the characteristics of 316 stainless steel, saves the consumption of metal resources, and at the same time saves equipment costs and ensures an extended service life.

[0065] In the disinfection machine of this embodiment, the conveying component 100 is relatively compact in design, and the synchronous transmission method is relatively novel. Compared with the traditional single-sided transmission, it is smaller in size, lower in noise, and has more convenient and advanced protective bearings, which reduces the time for installing and disassembling the first belt 102 and ensures the extended transmission needs at both ends of the conveyor belt, which is also a feature that traditional transmission methods do not have.

[0066] In some embodiments of the present application, there are multiple ultrasonic atomization devices 300 , which spray disinfectant toward the disinfection channel 201 .

[0067] The ultrasonic atomization device 300 sprays disinfectant from the top of the disinfection cabin 200 toward the disinfection channel 201 respectively. Since the luggage of the passengers needs to be transported within 30 minutes after the arrival of the flight, including the location of the rotary carousel conveyor from the aircraft cargo hold to the passenger arrival hall, the continuity and fast and efficient operation of the disinfection machine are the main evaluation indicators at busy airports. The disinfection machine of this embodiment is designed based on the loading port of the existing rotary carousel. The control mode of the disinfection machine is changed to three independent ultrasonic atomization devices 300, each of which operates independently and is built into the frame 1000 and disinfection cabin 200 of the disinfection machine. Even if a special situation occurs and one of the ultrasonic spray devices fails or reduces its effect, the other two ultrasonic atomization devices 300 can still maintain the normal operation of the disinfection machine; it has a certain redundancy feature, which is also not available in previous disinfection machines. Three relatively independent ultrasonic atomization devices provide disinfectant. The purpose of this is to reduce the interference between the three ultrasonic spray devices, without having to consider the problem of uneven usage of each nozzle, while improving the system reliability and redundancy of the equipment. Since the volume of a single ultrasonic atomization device 300 is relatively small, it is easy to install and deploy in relatively narrow spaces.

[0068] In some embodiments of the present application, the ultrasonic atomization device 300 includes:

[0069] A plurality of ultrasonic atomizing nozzles 301 are installed at the top of the disinfection chamber 200 and between two adjacent driving rollers 101 and facing the disinfection channel 201;

[0070] The supply component is installed on the frame 1000 and connected to the ultrasonic atomizing nozzle 301 to supply liquid to the ultrasonic atomizing nozzle 301.

[0071] The supply component obtains low-temperature chlorine-containing disinfectant, pumps a certain proportion of the disinfectant into the ultrasonic atomizing nozzle 301, maintains the atomized agent below 0.4 microns, and then fills the disinfection channel 201 through the spraying action of the ultrasonic atomizing nozzle 301 in three different directions to achieve disinfection of the luggage surface.

[0072] Among them, the ultrasonic atomizing nozzle 301 is set in an equilateral triangle. The design of the ultrasonic atomizing nozzle 301 fully considers the disinfection needs of the surrounding surface of the disinfected luggage at the airport. The ultrasonic atomizing nozzle 301 designed in the middle of the bottom is responsible for the bottom disinfection needs of the luggage. The other two are designed at the angle position of the observation windows on both sides of the top of the disinfection cabin 200. They are distributed in an inverted triangle shape when observed from the front of the disinfection machine. The advantage is that the diffuse mist is formed to maintain relative temperature, while preventing the luggage from scratching the ultrasonic nozzle and affecting the spray quality of the disinfection machine.

[0073] In some embodiments of the present application, the supply component includes:

[0074] The compressor 302 is mounted on the frame 1000 and connected to the air inlet of the ultrasonic atomizing nozzle 301;

[0075] The metering pump 304 is mounted on the frame 1000 and connected to the liquid inlet of the ultrasonic atomizing nozzle 301;

[0076] The liquid storage tank 305 is mounted on the frame 1000 and connected to the metering pump 304 .

[0077] The compressor 302 increases the air power output to the ultrasonic atomizing nozzle 301. At the same time, the metering pump 304 obtains low-temperature chlorine-containing disinfectant from the liquid storage tank 305 of the disinfection machine and pumps a certain proportion of the disinfectant into the ultrasonic atomizing nozzle 301, maintaining the atomized agent at a particle size below 0.4 microns. The atomized agent then fills the disinfection chamber 200 through the spray action of three different directions, thereby disinfecting the surface of the luggage.

[0078] In some embodiments of the present application, the supply component further includes:

[0079] The gas storage tank 306 is connected between the compressor 302 and the ultrasonic atomizing nozzle 301;

[0080] The solenoid valve is connected between the compressor 302 and the ultrasonic atomizing nozzle 301 and is electrically connected to the controller.

[0081] The oil-free permanent magnet variable frequency air compressor 302 increases the air power, and obtains stable driving gas after pressure stabilization and filtration in the air storage tank 306. The gas is output to the ultrasonic atomizing nozzle after the solenoid valve is controlled by the controller. At the same time, the metering pump 304 obtains the low-temperature chlorine-containing disinfectant from the liquid storage tank 305 of the disinfection machine, and pumps a certain proportion of the metering pump 304 into the ultrasonic atomizing nozzle 301, maintaining the mist agent below 0.4 microns. Then, through the spraying action of three different directions, the disinfection cabin 200 is filled to achieve the disinfection of the luggage surface.

[0082] Three relatively independent sets of oil-free permanent magnet motor 103 air compressor 302 operate independently, and are respectively equipped with air storage tank 306 and pressure reducing and regulating device, filter and automatic drainage device, independent solenoid valve drive, etc., to improve the reliability and redundancy of the equipment system. Since the volume of a single air pump is relatively small, it is convenient to install and deploy in relatively narrow spaces.

[0083] In some embodiments of the present application, the supply component further includes:

[0084] A refrigerator is installed on the liquid storage tank 305 and is used to cool the liquid storage tank 305 .

[0085] The refrigerator is designed to meet the needs of use in both summer and winter. The liquid storage tank 305 is welded and manufactured from 316 stainless steel, and its exterior is covered with flame-retardant thermal insulation material. The refrigerator is installed at the air inlet of the liquid storage tank 305 to maintain the disinfectant liquid between 7-10°C, ensuring the ambient temperature required for chlorine-containing disinfectants and reducing chlorine volatilization caused by high temperatures. Considering the needs of winter and severe cold seasons, a low-temperature heating element is installed at the bottom of the liquid storage tank 305. When the box temperature is below 1-2°C, it automatically heats the liquid, keeping it above 4°C for a long time. This temperature control function is also not considered in traditional disinfection machines.

[0086] In some embodiments of the present application, both sides of the disinfection chamber 200 are made of transparent tempered glass.

[0087] The staff can check the luggage disinfection process through the glass on both sides. When there is luggage left behind and moved in the disinfection chamber 200, it is also convenient to visually check the status of the luggage.

[0088] In some embodiments of the present application, the disinfection machine further comprises:

[0089] The recovery device is installed on the disinfection chamber 200 and is electrically connected to the controller.

[0090] The recovery device is a negative pressure recovery device. When luggage passes through the disinfection chamber 200, the diffused disinfectant mist expands from the inside out. Negative pressure recovery devices on either side of the disinfection chamber 200 absorb the diffused mist and direct it to the high-heat recovery fan, where it is degraded and discharged upward. Considering the needs of night flights, IED lighting strips are installed on both sides of the disinfection window to provide additional illumination at night. The synchronous transmission method of the drive roller 101 of this embodiment is also designed for confined spaces and has certain characteristics. Both ends also have the function of expanding the conveying function. Simultaneously, the drive roller 101 is driven by the cross-transmission transmission from the secondary drive wheels on both sides. This not only ensures reliable operation and stable luggage load transmission, but also has low noise operation characteristics. The bearing seats on both sides of the drive roller 101 provide excellent fixation and low noise operation. This prevents atomized disinfectant from entering the drive roller 101 and effectively protects the operating bearings. The replacement of the first belt 102 is simple and easy. Compared with traditional stainless steel chain drives, it has the advantages of low noise, reliable operation, effective prevention of disinfectant corrosion from the bearings, easy maintenance and replacement, and time-saving installation.

[0091] In some embodiments of the present application, the disinfection machine further comprises:

[0092] The fan is installed on the side of the disinfection chamber 200 at the exit of the disinfection channel 201 and faces the objects moving to the exit of the disinfection chamber 200.

[0093] The fan is an air curtain machine. After the disinfection machine has fully disinfected the luggage, the top-mounted air curtain machine at the rear dries the surface of the luggage. The drying temperature is adjustable between 50 and 80 degrees Celsius, which makes it easier for passengers to feel the slippery surface when retrieving their luggage.

[0094] In terms of noise elimination, front and rear equipment soundproofing rooms are set up, which are also the air inlet and exhaust rooms for equipment heat dissipation. The inner walls are filled with sound-absorbing sponges. Sponge sound-absorbing materials are set on the inner walls of the shell of the drive wheel and belt part of the running roller of the disinfection machine to achieve the purpose of reducing noise.

[0095] The disinfection machine is a floor-standing disinfection machine with a conveyor belt speed of 0.1-0.6 m / s, a rated conveying capacity of 60 kg, an average daily conveying of 10 tons, an air consumption of 318 liters / minute, a power of 6000 w, a medicine adding box of 100 liters, a waste liquid tank of 80 liters, and a disinfection cabin 200 and a medicine box body made of stainless steel 316, consuming 0.8 liters of medicine per hour.

[0096] Calculation of agent consumption: Assuming a maximum daily working time of 300 minutes, and assuming a demand of 0.8 liters per minute, 240 liters are required. Split into morning and afternoon shifts, the allocated agent tanks are 120 liters, with a maximum load of 130 liters. This means that during maximum working hours, agent needs to be refilled once per shift to ensure daily removal of unused agent while also meeting maximum demand. Based on the allocation of bulk agent plastic tanks, a maximum of three 40-liter barrels are required per shift, with a maximum daily demand of six barrels. Assuming the actual usage of each baggage handled, with a five-second delay for triggering the infrared spray, the actual number of agent used is between four and six barrels.

[0097] The disinfection machine can process 20 flights of luggage per day, and the average handling time is 15 minutes, which is qualified. The cumulative maximum daily workload time is: 20*15=300 minutes. The functions and performance of the disinfection machine installed in this project meet the disinfection work time requirements of transfer luggage and can meet the maximum daily transfer work time requirements.

[0098] Select the hoisting integral type according to the on-site installation conditions. Select multiple carousel baggage conveyors with relatively high daily usage in flights for testing. This will allow for the largest number of users to be tested. The specific location needs will be determined in consultation with Party A.

[0099] The disinfection machine needs to be reliably connected to the equipotential grounding protection line of the trailer luggage cart, disinfection machine, and carousel luggage conveyor casing, and has its own leakage protection function. When leakage is possible, the power switch will be automatically turned off and an alarm will be issued.

[0100] The pilot version of the disinfector is driven by a 2.2kW variable-frequency motor 103, with a maximum design operating mass of 80-100kg and an average belt speed of 0.3 m / s. Three oil-free permanent-magnet variable-frequency motors 103 drive three independent ultrasonic atomizing nozzles 301. Even if one ultrasonic nozzle fails during operation, the equipment will not stop operating. Each independent ultrasonic atomizing device is designed with an alarm to alert users of any anomalies.

[0101] In terms of noise suppression, the noise suppression of the disinfection machine in this embodiment is to place the reducer in the middle and lower part of the frame 1000, and install a ventilation air duct for equipment heat dissipation. A sponge is designed on the inner wall of the air duct for the purpose of absorbing noise. Since the main transmission part of the equipment is where the noise is, the present invention sets the transmission part of the equipment at the bottom and installs sound insulation panels on both sides for effective sound insulation and equipment safety protection.

[0102] This embodiment uses three relatively independent sets of metering pumps 304 to provide disinfectant to three sets of ultrasonic atomizing nozzles 301 respectively. The purpose of this is to reduce the interference between the three sets of ultrasonic atomizing nozzles 301, without having to consider the problem of uneven usage of each nozzle, while improving the system reliability and redundancy of the equipment. Since the volume of a single pump is relatively small, it is easy to install and deploy in relatively narrow spaces.

[0103] Three relatively independent sets of oil-free permanent magnet motors 103, air compressors 302, and air pumps operate independently, and are respectively equipped with air storage tanks 306, pressure reducing and regulating devices, filters, automatic drainage devices, and independent solenoid valve drives, etc., to improve the reliability and redundancy of the equipment system. Since the size of a single air pump is relatively small, it is easy to install and deploy in relatively narrow spaces.

[0104] The function of fast adding medicine and discharging waste liquid. Due to time constraints, the entire disinfection process of the disinfection machine is completed within 15 minutes. The required time is shorter than the dosing time requirements of other disinfection machines. During our research and development, we configured two sets of acid-resistant and corrosion-resistant diaphragm pumps, which can reach up to 60-80L per minute. Not only can the disinfectant that needs to be added be quickly added to the low-temperature liquid storage tank 305 at the bottom of the disinfection machine in a short time, but it can also discharge all the waste liquid from the waste liquid tank, completing the replenishment and discharge work in just 3 minutes. In addition, two electric valves are installed between the liquid storage tank 305 and the waste liquid tank, and a tee is designed in the middle. The middle is connected to the liquid extraction pump, and the three-way pipe serves as a bridge between the new agent and the waste agent tank, and is shared with the liquid extraction pump. The function of liquid storage and discharge can be managed by controlling the solenoid valve and the liquid extraction pump through the switch. When the two-way electric valve on the waste liquid tank side is opened and the liquid extraction pump is turned on, the system will quickly extract the liquid in the waste liquid tank. Similarly, the medicine liquid in the new agent liquid storage tank 305 can also be extracted. The solenoid valve of the liquid storage tank 305 can also be opened at the same time to discharge all the liquid in the two liquid storage tanks 305 from the machine at the same time. It can also be achieved without turning on the liquid extraction pump, and only opening the two electric valves to interconnect the waste liquid and the liquid storage tank 305.

[0105] To ensure adequate use in both summer and winter, liquid tank 305 is welded from 316 stainless steel and coated with flame-retardant thermal insulation. A chiller is installed at the air inlet of tank 305 to maintain the disinfectant at a temperature between 7-10°C, ensuring the required ambient temperature for chlorine-containing disinfectants and reducing chlorine volatilization caused by high temperatures. To accommodate winter and cold weather, a low-temperature heater is installed at the bottom of tank 305. This automatically warms the tank when the temperature drops below 1-2°C, maintaining the liquid above 4°C for extended periods. This temperature control feature is also missing from traditional disinfection machines.

[0106] Taking into account the busy airport baggage transfer needs, the disinfection machine only needs to continue to be used during the non-epidemic period. The set belt speed is 0.1-0.3 meters per second during the disinfection period. The fast belt speed can be set to 0.3-0.6 meters per second during the non-epidemic period. This is convenient for transfer needs in multi-functional scenarios.

[0107] In terms of load-bearing transfer, considering that the luggage at the airport is less than 30KG and there is the possibility of two luggage being disinfected on the equipment at the same time, the load design weight is 60-80KG. It uses a variable frequency reducer motor with a drive power of 1032.2KW, which can be competent for safe operation under high impact loads. It is particularly suitable for the use of airport rotary turntable conveyors in concentrated short-term transportation of a batch of luggage.

[0108] To supplement nighttime lighting, taking into account all-weather use and the need for enclosed local illumination, LED lighting strips are designed above the glass observation windows on both sides of the disinfection machine. They can automatically light up when the light is dim, ensuring sufficient lighting needs on site. At the same time, it also facilitates the local lighting needs of luggage handling at night.

[0109] Taking full consideration of the disinfection needs of the luggage around the airport, a bottom nozzle is designed in the middle of the bottom to be responsible for the bottom disinfection needs of the luggage. The other two designs are located at the angles of the observation windows on both sides of the top of the disinfection cabin 200. They are distributed in an inverted triangle shape when viewed from the front of the disinfection machine. The advantage is that they maintain the formation of diffuse mist at a relative temperature, while preventing the luggage from scratching the ultrasonic nozzle and affecting the spray quality of the disinfection machine.

[0110] Embedded mist-proof curtain design, located at the front and rear doors of the disinfection cabin 200 for entering and exiting the disinfection machine, is designed with louvered curtain-type mist-proof curtains to prevent the fog that diffuses during the disinfection process from drifting out of the disinfection cabin 200; the color is orange, the material is acid-resistant and corrosion-resistant, the clamping strip is made of 316 stainless steel, and it is a modular snap-on design, which is convenient for quick replacement and does not require on-site maintenance and repair, speeding up maintenance and reducing the downtime of equipment maintenance.

[0111] The shock-absorbing design takes into account the proximity of the airport's rotary turntable conveyor and the operation of luggage trucks transporting luggage. It is inevitable that heavy luggage will impact the drive roller 101 of the disinfection machine when unloading luggage. The overall design takes into account the impact load's need for the overall stability of the machine. The bottom of the disinfection machine is designed with an 800KG anti-vibration and shock-absorbing base, which is securely fixed to the ground to prevent other vehicles' wheels from colliding with the disinfection machine in case of accidents. It can still ensure that the main body does not move and will not affect the normal use of the airport's rotary turntable conveyor.

[0112] Infrared sensors on both sides of the disinfection machine exit automatically detect the luggage leaving the disinfection machine, perform counting and delay control, and facilitate remote monitoring and luggage calculation and verification needs. This disinfection machine takes into account the number control needs of luggage transfer personnel, and sets an infrared automatic calculator screen on the top of the luggage disinfection machine to facilitate the number verification of each time the luggage is transported for disinfection, providing convenience for staff to count the number.

[0113] The disinfection machine has an expanded belt transmission function. When the disinfection machine needs to be used in other places in the airport, the required height and height difference are different due to the different luggage disinfection scenarios. The disinfection machine is compatible with the driving needs of the import and export slopes. That is, when the ramp drive roller 101 with the bevel is installed on one side, the first belt 102 is connected, and the conveyor belt with the bevel surface can be driven by the disinfection machine. It is particularly suitable for the problem of luggage accumulation during security inspection. The bevel conveyor can alleviate the need for automatic luggage transportation and queuing when passengers are slow to retrieve their luggage relative to the machine during security inspection.

[0114] In order to meet the transportation needs during transfer, this disinfector takes into account the on-site installation and transfer hoisting needs. It is designed with hoisting holes on the top and bottom, and 4 hoisting rings are installed on the top load-bearing column to facilitate the whole machine to be hoisted onto the car for transportation and also facilitate rapid deployment.

[0115] The industrial quick-access interface design features a quick access door located in the middle of the bottom side of the sterilizer. Considering the need for rapid liquid addition and drainage, a quick industrial pipe interface is designed to be installed in the middle of the side of the liquid addition pump. When liquid addition is required, it can be opened for easy operation. In addition, an aviation power socket and a signal output socket are designed near the exit of the rotary turntable conveyor to facilitate power connection and remote control of signal output.

[0116] The observation window design perfectly meets the visual management needs of passengers and airport staff, allowing them to easily check the disinfection chamber's internal working conditions and observe the luggage disinfection process without losing their sight, ensuring passengers' sense of security. The use of double-layer tempered glass also reduces the use of 316 stainless steel and reduces manufacturing costs.

[0117] The disassembly and assembly of the sub-drive wheel and the first belt 102 of the drive roller 101 are conveniently performed by the roller sub-drive wheel compartments on both sides of the bottom of the disinfection machine. The operation and maintenance time of airport equipment is relatively short and the requirements are higher than those in other scenarios. The specially designed sub-drive wheel adopts a side-mounted expansion sub-drive wheel installation method, which is convenient for users to open and replace the sub-drive wheel and the first belt 102.

[0118] Taking into account factors such as batch manufacturing and cost reduction, the bottom frame 1000 is a relatively independent main body of the equipment, which can meet the needs of assembly line installation and debugging. In particular, after the installation and debugging are completed, it can be stacked and stored in the warehouse, saving a lot of production and storage space, making it more convenient to transport equipment over long distances on a large scale, and reducing transportation and warehousing costs.

[0119] The independent colored LED side-mounted signal lights located on the disinfection cabins 200 on both sides use independent signal indications and use various colors to simply judge the operating status of the equipment, making it easier for the operator to understand the operating status of the equipment.

[0120] The designed installation position of the liquid storage tank 305 and the waste liquid tank is located in the middle of the disinfection machine, which is also the intermittent position of the middle crossbeam of the equipment frame. This position design not only meets the liquid storage needs of the equipment, but also prevents the liquid storage tank 305 from being damaged by collisions with other external equipment and vehicles, and can also cooperate well to maintain the temperature control of the liquid storage tank 305.

[0121] Liquid level indication reminder: the liquid level float switch located in the liquid storage tank 305 is set at a high and low position, which can simply and effectively judge the height of the liquid storage level and promptly remind the staff to add or discharge the liquid;

[0122] Taking into account the need for liquid disinfection in the waste liquid tank, we designed an ultraviolet sterilization lamp in the waste liquid tank, relying on the equipment cooling, exhaust and silencer chamber to effectively and timely disinfect harmful bacteria and viruses remaining in the waste liquid, while increasing the temperature in the waste liquid tank and degrading chlorine-containing components.

[0123] The design considers installing disinfection machines in the luggage loading section outside the airport to the lobby to reduce the impact of the original pungent smell and the impact of noise on passengers.

[0124] Infrared sensors on both sides of the disinfection machine entrance automatically detect and automatically start the ultrasonic spray device to perform disinfection spray operations. This is accurate and effective, and the 1+1 redundant backup detection means that even if one probe fails, it can still work effectively, reducing downtime and maintenance time.

[0125] The height difference of the disinfection machine meets the on-site conditions, meets the matching requirements of the guardrail height of the rotary turntable conveyor and the height of the airport's luggage hauling trucks, and meets the airport's need for upgrade without modification;

[0126] Reduce the difficulty of operation, simplify the start and trigger buttons as much as possible, facilitate operation, and reduce cross-contact operation during the epidemic prevention and control period. The control button part of the equipment is mainly based on infrared trigger delay. When the luggage trailer approaches the front side of the disinfection machine, the metal proximity switch triggers the power closing design to trigger the equipment to start running.
