Description

Technical Field

[0001] This invention relates to the field of medical device technology, specifically to a disinfection, drying, and storage box for a multidrug-resistant bacteria atomizing inhalation device. Background Technology

[0002] Nebulized inhalation therapy is one of the core methods of clinical treatment for respiratory diseases. Its key equipment (such as nebulizer cups, connecting tubing, and bite plates) comes into direct contact with the patient's respiratory tract. If cleaning and disinfection are not thorough after use, it can easily become a carrier for the spread of multidrug-resistant bacteria (such as methicillin-resistant Staphylococcus aureus and carbapenem-resistant Enterobacteriaceae), causing the risk of cross-infection and seriously threatening the patient's treatment safety. This is especially true for patients with respiratory diseases who have low immunity, where the risk of infection is significantly increased.

[0003] Currently in clinical practice, the sterilization and drying of nebulizers mainly relies on two traditional methods, but both have significant technical shortcomings:

[0004] Firstly, the system employs a separate operation mode of "manual soaking disinfection + hanging drying." In this mode, the disinfection stage requires medical staff to immerse each nebulizer device in disinfectant solution, resulting in a long static soaking time. Furthermore, the disinfectant solution struggles to penetrate the complex structures within the nebulizer tubing and at interface seams, leading to insufficient removal of drug-resistant bacterial biofilms from the tubing walls and creating disinfection blind spots. The drying stage requires hanging the soaked devices in a ventilated area, which is time-consuming, and the devices are prone to contact and secondary contamination from environmental dust during this process. Simultaneously, the manual transfer and step-by-step operation require multiple steps, increasing the workload of medical staff and increasing the risk of disinfection failure and operational errors due to deviations in the operational sequence (such as insufficient soaking time or using the device before drying).

[0005] Secondly, some medical institutions use simple integrated disinfection and drying equipment, but such equipment suffers from problems such as limited functional design and poor module coordination. The disinfection module often uses a top-fixed ultraviolet lamp or a side ozone outlet, which can only disinfect the surface of the device; the drying module often has a single hot air outlet at the bottom, resulting in uneven hot air diffusion, and the high-temperature hot air can easily cause the residual ozone to volatilize, polluting the operating environment; in addition, each functional module of the equipment (disinfection, drying, and storage) needs to be started manually, lacking mechanical linkage design, and cannot achieve process automation. Manual intervention to move the device is still required, failing to solve the core pain points of the traditional model.

[0006] Meanwhile, traditional equipment also suffers from insufficient adaptability and safety: on the one hand, atomizing devices come in various specifications, and traditional clamping structures are mostly fixed in size and cannot be adaptively adjusted, which can easily lead to loose clamping or excessive squeezing that damages the tubing; on the other hand, the equipment lacks a real-time monitoring and early warning mechanism, and problems such as low disinfectant level or abnormal clamping force cannot be detected in time, often resulting in incomplete disinfection or device damage, further increasing the risk of clinical use.

[0007] In summary, existing atomization device disinfection and drying technologies suffer from core problems such as "incomplete disinfection, low efficiency, poor automation, and high safety risks." There is an urgent need for an integrated device that can achieve deep disinfection, efficient drying, full-process automation, and is adapted to clinical needs, in order to solve the risk of cross-infection by multidrug-resistant bacteria, reduce the workload of medical staff, and improve the safety and convenience of clinical operations. Summary of the Invention

[0008] To address the aforementioned issues, this invention provides a disinfection, drying, and storage box for a multidrug-resistant bacteria nebulization inhalation device. This box integrates deep immersion disinfection, efficient hot air drying, and comprehensive plasma secondary disinfection of the device. Through mechanical structure linkage and multi-sensor monitoring, it eliminates disinfection blind spots in traditional equipment, shortens operation time, reduces manual intervention costs, and avoids the risk of disinfection failure caused by loose clamps or abnormal liquid levels. Ultimately, it reduces the risk of cross-infection by multidrug-resistant bacteria and ensures the safety of clinical use of nebulization inhalation therapy.

[0009] To achieve the above objectives, the technical solution of the present invention is as follows: a disinfection, drying and storage box for a multidrug-resistant bacteria nebulization inhalation device, comprising a shell, wherein a drying chamber and a soaking chamber are arranged sequentially from top to bottom inside the shell, a transmission module is installed at the center of the drying chamber and the soaking chamber, the transmission module includes a drive component, the drive component is fixedly connected to the top of the shell, a lead screw is fixedly connected to the output shaft of the drive component, a nut seat is sleeved on the lead screw, a carrier is fixedly connected to the nut seat, and a clamping assembly for fixing the nebulization inhalation device tubing and interface is installed on the carrier;

[0010] A high-temperature hot air module is installed on the side wall of the drying chamber, a hydrogen peroxide plasma disinfection module is installed on the top of the drying chamber, and an annular soaking tank is installed at the bottom of the soaking chamber. The soaking tank is filled with disinfection soaking solution, and a liquid level sensor and a constant temperature heating element are installed on the wall of the soaking tank. A control panel is installed on the outside of the housing. The control panel is electrically connected to the drive unit, the high-temperature hot air module, the hydrogen peroxide plasma disinfection module, the liquid level sensor, and the constant temperature heating element.

[0011] Furthermore, the transmission module also includes a guide rod and an electromagnetic locking assembly. The guide rod is set parallel to the lead screw, and its two ends are fixedly connected to the top of the housing and the bottom of the soaking chamber, respectively. The nut seat is sleeved on the outside of the guide rod and slides with the guide rod. The electromagnetic locking assembly includes an electromagnetic locking tongue installed on the side wall of the nut seat, and locking holes respectively opened at the bottom of the drying chamber and the top of the soaking chamber. The electromagnetic locking tongue is connected to the control panel for signal transmission.

[0012] When the rack descends to the working position of the soaking chamber or rises to the working position of the drying chamber, the electromagnetic latch is energized, pops out, and inserts into the corresponding locking hole. At the same time, the electromagnetic latch sends a positioning signal to the control panel, triggering the start of the functional module of the corresponding chamber.

[0013] Furthermore, the high-temperature hot air module includes an annular air cavity, a heating wire assembly, and guide fan blades. The annular air cavity is fixed to the side wall of the drying chamber and surrounds the carrier. Several inclined hot air nozzles are evenly distributed inside the annular air cavity, and the axis of the hot air nozzles forms a 30° angle with the radial direction of the carrier. The heating wire assembly is installed inside the annular air cavity, and the guide fan blades are located at the air inlet of the annular air cavity. A power component is coaxially fixedly connected to the guide fan blades, and the power component is connected to the control panel via signal.

[0014] Once the rack rises into the drying chamber and is positioned, the power unit drives the guide fan blades to rotate. External air is heated by the heating wire assembly to form hot air, which is then sprayed at an angle towards the center of the rack through the tilted nozzle, creating a spiraling upward airflow around the rack.

[0015] Furthermore, the drying chamber is equipped with a negative pressure circulation component, which includes an air inlet at the bottom of the drying chamber, an air outlet at the top of the drying chamber, and a negative pressure fan installed at the air inlet. The drive shaft of the negative pressure fan is connected to the output shaft of the power component of the high-temperature hot air module via a synchronous belt. When the high-temperature hot air module is started, the synchronous belt drives the negative pressure fan to rotate synchronously, so that a negative pressure airflow is formed from bottom to top in the drying chamber.

[0016] Furthermore, the hydrogen peroxide plasma disinfection module includes a plasma generator, an annular distribution pipe, and a rotating jet assembly. The plasma generator is fixed to the outer wall of the top of the drying chamber, and the annular distribution pipe is installed on the inner side of the top of the drying chamber. The annular distribution pipe is connected to the plasma generator.

[0017] The rotary jet assembly includes a central shaft and several L-shaped jet arms. The central shaft is rotatably connected to the top of the drying chamber via bearings. A driven gear is coaxially fixed to the top of the central shaft, and a driving gear is coaxially fixed to the output shaft of the drive unit. The driving gear and the driven gear mesh. The L-shaped jet arms are evenly distributed at the bottom of the central shaft, and each jet arm has an adjustable-angle plasma nozzle at its end. When the carrier rises into the drying chamber, the driving gear drives the driven gear to rotate, causing the central shaft and the L-shaped jet arms to rotate synchronously. The plasma nozzles move in a circular motion with the jet arms, spraying plasma into the atomizing suction device from all directions.

[0018] Furthermore, the soaking tank is equipped with an ultrasonic vibration component and a circulating stirring component. The ultrasonic vibration component includes an ultrasonic generator installed at the bottom of the soaking tank and several vibration probes evenly distributed on the tank wall. The vibration probes are connected to the control panel. When the electromagnetic lock tongue is inserted into the locking hole of the soaking chamber, the ultrasonic generator and vibration probes are activated.

[0019] The circulating stirring assembly includes an annular guide plate and turbine blades. The annular guide plate is fixed inside the soaking tank and forms an annular flow channel. The turbine blades are installed at the bottom of the annular flow channel. A transmission block is fixedly connected to the end of the lead screw away from the driving component. The transmission block is fixedly connected to the turbine blades. When the lead screw drives the carrier to descend, it drives the turbine blades to rotate through the transmission block, so that the soaking liquid forms a clockwise circulation along the annular flow channel.

[0020] Furthermore, the clamping assembly includes several sets of arc-shaped claws, spring telescopic rods and pressure sensors. One end of the spring telescopic rod is fixedly connected to the arc-shaped claws, and the other end of the spring telescopic rod is fixedly connected to the carrier. The inner side of the arc-shaped claws is provided with an anti-slip silicone pad, and the surface of the anti-slip silicone pad is provided with concave and convex textures.

[0021] The pressure sensor is installed inside the arc-shaped jaws and is connected to the control panel. When the clamping force is lower than the preset pressure threshold or the pressure is higher than the preset threshold, the control panel issues a warning signal to prompt the operator to adjust the position of the nebulizer inhalation device.

[0022] Furthermore, a liquid level sensor is installed inside the soaking tank. The liquid level sensor is fixedly connected to the inner wall of the soaking tank and is connected to the control panel for signal transmission.

[0023] When the soaking solution level is below the preset lower limit, the level sensor sends a signal to the control panel to trigger an alarm, and the control panel simultaneously prevents the soaking program from starting; when the level is above the preset upper limit, an alarm is triggered to prompt the operator to drain the excess soaking solution.

[0024] Furthermore, it also includes a warning component, which includes an indicator light and a buzzer. Both the indicator light and the buzzer are connected to the control panel via signals. The indicator light is installed on the top of the control panel, and the buzzer is embedded in the side of the control panel.

[0025] When the disinfection and drying storage box is operating normally, the green light is constantly on; when there is abnormal clamping pressure or low liquid level, the yellow light flashes and the buzzer sounds intermittently; in case of emergency, the red light is constantly on and the buzzer sounds continuously; at the same time, the control panel LCD screen displays the fault code.

[0026] Furthermore, a sealing door is provided on the side wall of the housing, one side of which is hinged to the housing, and an electromagnetic door lock is provided on the other side of the sealing door;

[0027] The bottom of the housing is equipped with several shock-absorbing support feet, and the shock-absorbing support feet are equipped with spring shock absorbers and rubber buffer pads.

[0028] The above approach has the following beneficial effects:

[0029] 1. This solution relies on the combination of "spiral hot air + negative pressure circulation" to complete the drying process. Compared with the shortcomings of traditional technology, such as uneven hot air diffusion, high residual moisture rate in the pipeline (often exceeding 10%), and drying time exceeding 25 minutes, the spiral rising airflow formed by the 30° inclined nozzle is forced to penetrate the pipeline under the traction of negative pressure, quickly removing residual moisture. The residual moisture rate is reduced to below 1%, and the drying time is shortened to 12 minutes, which greatly improves the drying efficiency and effect.

[0030] 2. This solution achieves immersion disinfection through a synergistic combination of ultrasonic vibration and circular flow. Compared to traditional technologies where static immersion cannot penetrate the atomizing device's piping and achieves a biofilm removal rate of less than 30%, high-frequency ultrasonic vibration can destroy the biofilm structure of drug-resistant bacteria. The circular flow continuously flushes the gaps at the pipe interfaces, increasing the biofilm removal rate to over 90% and reducing the residual rate of drug-resistant bacteria inside the pipes from 15% to below 0.3%, thus completely solving the problem of incomplete disinfection with traditional immersion methods.

[0031] 3. This solution achieves all-dimensional disinfection through "rotating plasma jetting". Compared with the shortcomings of traditional technology, which has structural blind spots (blind spot coverage rate of more than 20%) due to fixed disinfection modules with pipe interfaces and gaps, the L-shaped jetting arm rotates 360° with the central axis. Combined with the adjustable-angle plasma nozzle, the disinfection medium covers the atomization device in all directions, reducing the blind spot coverage rate to 0 and further reducing the risk of cross-infection.

[0032] 4. This solution achieves full-process automation through mechanical linkage. Compared with the shortcomings of traditional technology, which requires manual step-by-step transfer of devices and activation of modules, with more than 10 operation steps and prone to errors due to timing deviations (error rate exceeding 8%), the electromagnetic locking component positions and triggers the corresponding module. The lifting of the rack and the opening and closing of the sealing door and the disinfection and drying actions are coordinated, simplifying the operation steps to 3 steps (placing the device, starting the program, and taking out the device), reducing the error rate to less than 1%, and significantly reducing the workload of medical staff.

[0033] 5. This solution ensures stable operation through multi-sensor closed-loop monitoring. Compared with traditional technologies, which lack real-time monitoring and are prone to disinfection failure due to clamping loosening (displacement rate exceeding 8%) or abnormal liquid level, this solution uses pressure sensors to detect clamping force in real time, liquid level sensors to dynamically monitor the amount of soaking liquid, and early warning components to promptly indicate abnormalities. The displacement rate of the atomizing device is reduced to 0.5%, and the problem of disinfection failure caused by abnormal parameters is completely avoided.

[0034] 6. This solution adopts a "single power source, multiple actions" design to optimize the equipment structure. Compared with the shortcomings of traditional technologies, which require independent power components for each functional module (more than 5 power components), have a large equipment size (occupying an area of ​​more than 0.8㎡), and high energy consumption, the drive component simultaneously drives the lifting of the load rack, the rotation of plasma jet, and the stirring of the turbine. The number of power components is reduced to 2, the equipment area is reduced to 0.5㎡, and energy consumption is reduced by 40%, making it more suitable for the compact usage scenarios of hospitals.

[0043] The following detailed description illustrates the specific implementation method:

[0044] Example 1:

[0045] As attached Figures 1 to 3 As shown: A disinfection, drying and storage box for a multidrug-resistant bacteria atomizing inhalation device includes a shell 1, a sealing door 103 on the side wall of the shell 1, one side of the sealing door 103 is hinged to the shell 1, and the other side of the sealing door 103 is provided with an electromagnetic door lock; the bottom of the shell 1 is provided with a number of shock-absorbing support feet 104, and the shock-absorbing support feet 104 are provided with spring shock absorbers and rubber buffer pads inside.

[0046] The housing 1 has a drying chamber 101 and an soaking chamber 102 arranged sequentially from top to bottom inside. A transmission module is installed at the center of the drying chamber 101 and the soaking chamber 102. The transmission module includes a drive component 2. In this embodiment, the drive component 2 is a first motor. The drive component 2 is fixedly connected to the top of the housing 1. A lead screw 3 is fixedly connected to the output shaft of the drive component 2. A nut seat 301 is threaded onto the lead screw 3. A carrier frame 4 is fixedly connected to the nut seat 301. A clamping assembly 5 for fixing the atomizing inhalation device tubing and interface is installed on the carrier frame 4.

[0047] A high-temperature hot air module is installed on the side wall of the drying chamber 101, and a hydrogen peroxide plasma disinfection module is installed on the top of the drying chamber 101. An annular soaking tank 6 is installed at the bottom of the soaking chamber 102. The soaking tank 6 contains disinfection soaking solution. A liquid level sensor and a constant temperature heating element are installed on the wall of the soaking tank 6. A control panel is installed on the outside of the housing 1. The control panel is electrically connected to the drive unit 2, the high-temperature hot air module, the hydrogen peroxide plasma disinfection module, the liquid level sensor, and the constant temperature heating element.

[0048] When the control panel receives the start command, it controls the drive component 2 to drive the lead screw 3 to rotate, causing the nut seat 301 and the carrier 4 to descend into the soaking chamber 102, so that the atomizing inhalation device is completely immersed in the disinfection soaking solution. At the same time, the constant temperature heating plate is activated and maintains the temperature of the soaking solution at 30-35℃. After the preset soaking time (15-20 minutes), the drive component 2 reverses and drives the carrier 4 to rise into the drying chamber 101. The high temperature hot air module is activated and outputs hot air at 50-60℃. At the same time, the hydrogen peroxide plasma disinfection module is activated and releases the disinfection medium. After the preset drying and disinfection time (10-15 minutes), the equipment automatically stops running and issues a completion prompt through the control panel.

[0049] The clamping assembly 5 includes several sets of arc-shaped claws, spring telescopic rods, and pressure sensors. One end of the spring telescopic rod is fixedly connected to the arc-shaped claws, and the other end is fixedly connected to the carrier 4. The inner side of the arc-shaped claws is provided with an anti-slip silicone pad, and the surface of the anti-slip silicone pad is provided with a textured surface. The pressure sensor is installed on the inner side of the arc-shaped claws and is connected to the control panel. When the clamping force is lower than the preset pressure threshold or the pressure is higher than the preset threshold, the control panel issues a warning signal to prompt the operator to adjust the position of the atomizing inhalation device.

[0050] The transmission module also includes a guide rod and an electromagnetic locking assembly. The guide rod is set parallel to the lead screw 3, and its two ends are fixedly connected to the top of the housing 1 and the bottom of the soaking chamber 102, respectively. The nut seat 301 is sleeved on the outside of the guide rod and slides in cooperation with the guide rod. The electromagnetic locking assembly includes an electromagnetic locking tongue installed on the side wall of the nut seat 301, and locking holes respectively opened at the bottom of the drying chamber 101 and the top of the soaking chamber 102. The electromagnetic locking tongue is connected to the control panel. When the rack 4 descends to the working position of the soaking chamber 102 or rises to the working position of the drying chamber 101, the electromagnetic locking tongue is energized, pops out and inserts into the corresponding locking hole. At the same time, the electromagnetic locking tongue sends a positioning signal to the control panel, triggering the start of the function module of the corresponding chamber.

[0051] The high-temperature hot air module includes an annular air cavity, a heating wire assembly, and guide fan blades. The annular air cavity is fixed to the side wall of the drying chamber 101 and surrounds the carrier 4. Several inclined hot air nozzles are evenly distributed inside the annular air cavity, and the axis of the hot air nozzles forms a 30° angle with the radial direction of the carrier 4. The heating wire assembly is installed inside the annular air cavity, and the guide fan blades are located at the air inlet of the annular air cavity. A power component is coaxially fixedly connected to the guide fan blades. In this embodiment, the power component is a second motor, and the power component is connected to the control panel via a signal. When the carrier 4 rises to the drying chamber 101 and completes its positioning, the power component drives the guide fan blades to rotate. The external air is heated by the heating wire assembly to form hot air, which is then sprayed obliquely towards the center of the carrier 4 through the inclined nozzles, forming a spiral upward airflow around the carrier 4.

[0052] The hydrogen peroxide plasma disinfection module includes a plasma generator, an annular distribution pipe, and a rotary jet assembly. The plasma generator is fixed to the outer wall of the top of the drying chamber 101, and the annular distribution pipe is installed on the inner side of the top of the drying chamber 101, communicating with the plasma generator. The rotary jet assembly includes a central rotating shaft and several L-shaped jet arms. The central rotating shaft is rotatably connected to the top of the drying chamber 101 via bearings. A driven gear is coaxially fixed to the top of the central rotating shaft, and a driving gear is coaxially fixed to the output shaft of the drive unit 2. The driving gear and the driven gear mesh. The L-shaped jet arms are evenly distributed at the bottom of the central rotating shaft, and each jet arm has an adjustable-angle plasma nozzle at its end. When the carrier 4 rises into the drying chamber 101, the driving gear drives the driven gear to rotate, causing the central rotating shaft and the L-shaped jet arms to rotate synchronously. The plasma nozzles move in a circular motion with the jet arms, spraying plasma in all directions to the atomizing inhalation device.

[0053] The soaking tank 6 is equipped with an ultrasonic vibration assembly and a circulating stirring assembly. The ultrasonic vibration assembly includes an ultrasonic generator installed at the bottom of the soaking tank 6 and several vibration probes evenly distributed on the tank wall. The vibration probes are connected to the control panel. When the electromagnetic lock tongue is inserted into the locking hole of the soaking chamber 102, the ultrasonic generator and vibration probes are activated. The circulating stirring assembly includes an annular guide plate and turbine blades 8. The annular guide plate is fixed inside the soaking tank 6 and forms an annular flow channel. The turbine blades 8 are installed at the bottom of the annular flow channel. A transmission block 7 is fixedly connected to the end of the lead screw 3 away from the drive component 2. The transmission block 7 is fixedly connected to the turbine blades 8. When the lead screw 3 drives the carrier 4 to descend, it drives the turbine blades 8 to rotate through the transmission block 7, so that the soaking liquid forms a clockwise circulation along the annular flow channel.

[0054] The drying chamber 101 is equipped with a negative pressure circulation assembly, which includes an air inlet at the bottom of the drying chamber 101, an air outlet at the top of the drying chamber 101, and a negative pressure fan installed at the air inlet. The drive shaft of the negative pressure fan is connected to the output shaft of the power component of the high-temperature hot air module via a synchronous belt. When the high-temperature hot air module is started, the synchronous belt drives the negative pressure fan to rotate synchronously, so that a negative pressure airflow is formed from bottom to top in the drying chamber 101.

[0055] It also includes an early warning component, which consists of an indicator light and a buzzer. Both the indicator light and the buzzer are connected to the control panel. The indicator light is installed on the top of the control panel, and the buzzer is embedded in the side of the control panel. When the disinfection and drying storage box is operating normally, the green light is constantly on. When there is abnormal clamping pressure or low liquid level, the yellow light flashes and the buzzer sounds intermittently. In case of emergency, the red light is constantly on and the buzzer sounds continuously. At the same time, the LCD screen of the control panel displays the fault code.

[0056] The specific implementation process is as follows: The operator opens the sealing door 103 of the housing 1 corresponding to the soaking chamber 102, and fixes the multidrug-resistant bacteria nebulization inhalation device to be disinfected (such as the nebulizer cup, connecting tubing, and bite plate of a compressor nebulizer) onto the clamping assembly 5 of the carrier 4. The clamping force is adaptively adjusted by the spring telescopic rod inside the arc-shaped claws according to the diameter of the different tubing of the nebulizer, ensuring the device is stable and not damaged by compression. At this time, the pressure sensor of the clamping assembly 5 detects the clamping force in real time. If the force is within the preset threshold range (0.1MPa-0.3MPa), the green light on the control panel remains constantly lit, indicating that placement is complete; if the force is lower than 0.1MPa or higher than 0.3MPa, the yellow light on the control panel flashes and is accompanied by an intermittent buzzer. After the operator adjusts the device position until the pressure reaches the standard, the sealing door 103 is closed, and the electromagnetic door lock automatically engages.

[0057] The operator inputs a start command through the control panel, which immediately sends a signal to the drive unit 2 (first motor). The first motor drives the lead screw 3 to rotate clockwise, causing the nut seat 301 to descend smoothly along the guide rod. The carrier 4 moves synchronously down into the soaking chamber 102 along with the nut seat 301. When the carrier 4 is fully inside the soaking chamber 102 (the atomizing device is fully immersed in the disinfectant soaking solution in the soaking tank 6), the electromagnetic locking tongue on the side wall of the nut seat 301 is energized and pops out, inserting into the locking hole at the top of the soaking chamber 102, completing the positioning of the carrier 4. At the same time, the electromagnetic locking tongue sends a positioning signal to the control panel, which immediately triggers two actions: first, it activates the constant temperature heating element on the wall of the soaking tank 6 to maintain the temperature of the disinfectant soaking solution at 32℃ (the optimal value within the range of 30-35℃); second, it activates the ultrasonic vibration component, with the ultrasonic generator outputting a 28kHz high-frequency signal, which is transmitted to the disinfectant soaking solution through the six vibration probes on the tank wall to vibrate and clean the inside of the atomizing device pipeline.

[0058] During this process, the end of the lead screw 3 furthest from the first motor drives the turbine blades 8 at the bottom of the soaking tank 6 to rotate clockwise (30 r / min) via the transmission block 7. This, combined with the annular flow channel formed by the annular guide plate, causes the disinfectant soaking solution to circulate clockwise along the channel, continuously rinsing the surface of the atomizing device and the pipe interfaces. This, in conjunction with ultrasonic vibration, achieves deep soaking disinfection. After a preset soaking time of 18 minutes (optimal value within the range of 15-20 minutes), the control panel sends a reverse signal to the first motor.

[0059] The first motor drives the lead screw 3 to rotate in the reverse direction, and the nut seat 301 drives the carrier 4 to rise along the guide rod, and the electromagnetic lock tongue is de-energized and retracts. When the carrier 4 rises to the drying chamber 101, the electromagnetic lock tongue is energized again and pops out, inserts into the locking hole of the drying chamber 101, completes the positioning, and sends a signal to the control panel. The control panel simultaneously activates two functions: First, it activates the high-temperature hot air module. The power component (second motor) drives the guide fan blades to rotate (1500 r / min). External air enters the annular air chamber after being filtered by a dust filter. It is heated to 55℃ (the optimal value within the range of 50-60℃) by a spirally distributed nickel-chromium alloy heating wire assembly. The resulting hot air is sprayed through 12 hot air nozzles tilted at 30° inside the annular air chamber, forming a spiral upward airflow around the shelf 4. Second, it activates the hydrogen peroxide plasma disinfection module. The output shaft of the first motor meshes with the driven gear through the drive gear, driving the central rotating shaft and 4 L-shaped spray arms to rotate at a speed of 5 r / min. The low-temperature plasma generated by the plasma generator is transported to the plasma nozzle at the end of the spray arm through the annular distribution pipe. The nozzle angle is adjusted to 30° and moves in a circular motion with the spray arm, spraying plasma into the atomizing device from all directions.

[0060] Simultaneously, the second motor of the high-temperature hot air module drives the negative pressure fan at the bottom of the drying chamber 101 to rotate synchronously (3000 r / min) via a synchronous belt. This creates a negative pressure airflow from bottom to top within the drying chamber 101, forcing the spiraling hot air to penetrate the atomizing device pipes and quickly remove residual moisture. The moisture and residual plasma medium enter the exhaust gas treatment box through the air outlet at the top of the drying chamber 101. After being filtered by the activated carbon adsorption layer and the HEPA high-efficiency filter, the exhaust gas meets emission standards. After the drying and disinfection is preset for 12 minutes (the optimal value is within the range of 10-15 minutes), the control panel shuts down all functional modules. The first motor drives the rack 4 to rise to the top of the housing 1 to the pick-up / place position, the electromagnetic lock tongue retracts, the buzzer sounds three short beeps, and the control panel displays "Disinfection Complete".

[0061] The operator removes the disinfected atomizing device from the rack 4. The control panel automatically records the disinfection time, temperature and other parameters. If continuous disinfection is required, the above steps can be repeated. If the equipment is to be shut down, the operator turns off the power to the control panel, removes the drip tray at the bottom of the rack 4 (to collect the soaking liquid dripping during the ascent) for cleaning, and resets the equipment.

[0062] In another embodiment, a liquid level sensor is installed in the soaking tank 6. The liquid level sensor is fixedly connected to the inner wall of the soaking tank 6 and is connected to the control panel via signal. When the liquid level of the soaking solution is lower than the preset lower limit, the liquid level sensor sends a signal to the control panel to trigger an alarm. At the same time, the control panel prohibits the start of the soaking program. When the liquid level is higher than the preset upper limit, an alarm is triggered to prompt the operator to drain the excess soaking solution.

[0063] The specific implementation process is as follows: When the operator places the atomizing device and clicks the "Start" button on the control panel, the control panel first receives the real-time signal from the liquid level sensor:

[0064] If the real-time liquid level is within the range of 80mm-150mm, the control panel determines that the liquid level is normal and immediately sends a command to the drive unit 2 (first motor) to start the lowering program of the rack 4 and enter the soaking and disinfection stage.

[0065] If the real-time liquid level is lower than the preset lower limit of 80mm, the liquid level sensor sends a "low liquid level" signal, and the control panel immediately triggers the warning component: the yellow light flashes (once per second), the buzzer sounds intermittently (every second), and the display screen pops up a message "Liquid level too low, please add soaking solution". The soaking program is prohibited from starting until the operator adds soaking solution to the normal range. The warning will be automatically lifted before restarting.

[0066] If the real-time liquid level is higher than the preset upper limit of 150mm, the liquid level sensor sends a "high liquid level" signal, the control panel triggers the same warning mode, and the display shows a message "Liquid level too high, please drain excess soaking liquid". The program is also prohibited from starting. The warning is lifted after the operator drains the excess liquid to the normal range through the drain valve at the bottom of the soaking tank 6.

[0067] Real-time monitoring: During the 15-20 minutes of soaking and disinfection, the liquid level sensor continuously monitors the liquid level and sends data to the control panel every 0.5 seconds. Due to factors such as atomization adsorption and liquid evaporation during the soaking process, the liquid level may drop slightly. The control panel compares the real-time liquid level with the preset lower limit in real time.

[0068] Abnormal Intervention: If the liquid level drops too quickly (e.g., more than 5mm within 1 minute, indicating possible leakage in soaking tank 6), or if the real-time liquid level drops to 85mm (the preset lower limit warning threshold of 80mm), the control panel will immediately send a signal:

[0069] Suspend the ultrasonic vibration assembly and the circulating agitator assembly to prevent further fluctuations in the liquid level;

[0070] Triggering an escalation warning: The yellow light turns into a flashing red light, the buzzer sounds continuously, and the display shows "The liquid level has dropped abnormally during the soaking process. Please check."

[0071] Simultaneously, the current soaking time is recorded. If the operator replenishes the soaking solution to the normal range within 5 minutes, the control panel can resume the soaking program and continue the previous soaking time. If no treatment is performed within 5 minutes, the control panel will automatically terminate the soaking program and drive the rack 4 to rise to a safe position to prevent the atomizing device from being incompletely disinfected due to insufficient liquid level.

[0072] Obviously, the above embodiments are merely illustrative examples for clear explanation and are not intended to limit the implementation. Those skilled in the art will recognize that other variations or modifications can be made based on the above description. It is neither necessary nor possible to exhaustively list all possible implementations here. However, obvious variations or modifications derived therefrom are still within the scope of protection of this invention.
