[0031] To address the aforementioned issues, this application provides an air shower medicine cabinet that can clean the outer packaging surface of toxic medicines using an air shower method, solving the problems of toxic substances adhering, spilling, and flying, thereby preventing adverse events such as poisoning.

[0032] The technical solutions of the embodiments of this application are described in detail below with reference to the accompanying drawings.

[0033] See Figures 1-4 The air shower medicine cabinet provided in this embodiment of the utility model includes:

[0034] Cabinet 1, which has several horizontally spaced perforated panels 2 inside, a filter layer on the top of the cabinet 1, a filter adsorption component inside the filter layer, an air supply layer on the inner side wall of the cabinet 1, an air supply layer with several air supply holes, and a cabinet door 3.

[0035] The air shower system includes air nozzles 4 located in the air supply holes and a circulating fan;

[0036] The circulation system includes an exhaust duct 5 that connects to the filter jacket and an air inlet duct that connects to the air supply jacket. The exhaust duct 5 is connected to the interior of the cabinet 1 through a filter adsorption component, and the circulation fan is located inside the air inlet duct.

[0037] Specifically, the cabinet 1 has a rectangular structure with a top surface, a bottom surface, and four sides. The top surface, bottom surface, and four sides form a sealed medicine storage space. A filter layer is provided on the top surface, and air supply layers are provided on three of the sides. Perforated panels 2 are installed at intervals within the medicine storage space, and medicines are placed on the perforated panels 2. In some embodiments, the perforated panels 2 are made of plastic and have several fine holes, for example, with a pore diameter of 0.5 mm. A filter adsorption assembly is filled in the filter layer on the top surface of the cabinet 1. When airflow carrying toxic substances passes through the filter adsorption assembly, it can clean and filter out the toxic powder or particles. A cabinet door 3 is installed on one side of the cabinet 1, sealing the medicine storage space. In some embodiments, the cabinet door 3 and the cabinet 1 can be connected by a rotating seal or a sliding seal. The cabinet 1 has an air supply jacket on three sides, which is the inner wall of the medicine storage space. The air shower nozzles 4 are installed in the air supply holes of the air supply jacket. The circulating fan is installed in the air inlet pipe. After the circulating fan is started, it can form a strong airflow. The airflow is blown onto the perforated plate 2 through the air nozzles 4, thereby cleaning the toxic dust, particles or toxic volatile substances adhering to the outer surface of the packaging.

[0038] Correspondingly, the exhaust duct 5 is also equipped with an exhaust fan. When the medicine placed on the perforated plate 2 is air-showered by the air shower system, the exhaust fan can be started at the same time to increase the airflow speed inside the cabinet 1.

[0039] In this embodiment, the outer packaging of the medicine is efficiently cleaned by an air shower system to reduce the residue of toxic substances; the circulation system ensures air circulation and purification, prevents the accumulation of pollutants, and improves storage safety.

[0040] Furthermore, the cabinet door 3 is rotatably connected to the cabinet body 1 via a damping hinge 6, and a sealing strip is provided at the closing point of the cabinet body 1 and the cabinet door 3. The damping hinge 6 can freely control the opening and closing degree of the cabinet door 3, allowing the cabinet door 3 to close slowly to avoid vibration causing toxic substances to fly out, and the sealing strip enhances the sealing performance of the cabinet body 1 to prevent the leakage of harmful substances.

[0041] Furthermore, the damping hinge 6 includes a first hinge 61 and a second hinge 62. The first hinge 61 is provided with a first bushing, and the second hinge 62 is provided with a second bushing. The first bushing and the second bushing are staggered and form a bushing structure. A pin 63 passes through the bushing structure, and a damping component 64 is sleeved inside the pin 63. The damping component 64 includes stacked gaskets and damping washers. The bushing structure and the pin 63 can rotate relative to each other to compress the damping component 64.

[0042] Specifically, each second bushing is located between two adjacent first bushings. More specifically, there are two first bushings and one second bushing, with the second bushing positioned between the two first bushings. It is understood that in other embodiments, the number of both first and second bushings may be one. The pin 63 is a rod-shaped component, with one end radially enlarged to form a head, and the other end having an internal threaded groove. A bolt is threaded into the internal threaded groove. The pin 63 passes through the bushing structure and is fixed to the bushing structure by the bolt and the head of the pin 63. One end of the damping assembly 64 contacts the head of the pin 63, and the other end contacts the bushing structure. When a set of damping assemblies 64 is subjected to force and rotates, the damping assemblies 64 rotate synchronously, and the damping assemblies 64 move against each other to generate friction, ensuring that the pin 63 can rotate and maintain a fixed position at the current angle during rotation, thereby fixing the opening and closing angle of the cabinet door 3. In a preferred embodiment, the damping washer may be made of silicone material, and the Shore hardness of the selected silicone material is between 35 and 55.

[0043] Based on the above specific embodiments, the perforated plate 2 has upwardly bent baffles around its four edges. These baffles prevent the medicine from slipping or shifting, ensuring the medicine remains stable during air showering. Furthermore, the perforated plate 2 is also equipped with a clamping mechanism 7 for securing the medicine, preventing the medicine packaging from tipping over due to airflow impact, thus improving cleaning efficiency and safety. In some embodiments, the clamping mechanism 7 includes a mounting housing and two clamping arms rotatably connected to the mounting housing. The two clamping arms are connected by a spring, and the mounting housing is bolted to the perforated plate 2. Alternatively, the clamping mechanism 7 also consists of a clamping arm and a spring. The clamping arm is placed horizontally on the perforated plate 2, and its end is rotatably connected to the perforated plate 2 via a mounting lug and a pivot. That is, the clamping arm rotates relative to the plane of the perforated plate 2. The spring connects the clamping arm and the perforated plate 2, thus securing the medicine packaging through the perforated plate 2 and the clamping arm.

[0044] Furthermore, a mechanical lock is installed on cabinet door 3, and a sensor is also installed on cabinet door 3. The sensor is used to detect the open state of cabinet door 3 and to control the start and stop of the circulating fan. The sensor is a reed switch or a photoelectric sensor, installed at the point where cabinet body 1 and cabinet door 3 are closed, i.e., inside the sealing strip. When the reed switch is open (or the optical path of the photoelectric sensor is interrupted), it outputs a high-level signal; when the reed switch is closed (or the optical path of the photoelectric sensor is connected), it outputs a low-level signal. More specifically, the sensor is a reed switch, and its signal line is connected to the PA1 pin of the main control module. The main control module has a built-in microcontroller that detects the level state of the PA1 pin through program logic. When PA1 is high, it controls the PC13 pin to output a low level, driving the relay module to disconnect the fan power supply; when PA1 is low for 3 seconds, the PC13 pin outputs a high level, the relay closes, and the fan starts. The mechanical lock enhances the security of cabinet body 1, and the sensor controls the start and stop of the fan, reducing energy consumption and ensuring that the system only operates when cabinet door 3 is closed.

[0045] Furthermore, a drug information entry device and a display screen are provided on the outside of cabinet door 3. The drug information entry device is used to record drug information, and the display screen is used to display the storage information of the drugs in cabinet door 3. Specifically, the drug information entry device integrates a barcode scanner, an RFID reader / writer, and a touch screen, and is connected to the main control module via an SPI interface. Drug data is stored on a MicroSD card (SanDisk Ultra 32GB) and supports export in CSV format.

[0046] The display screen shows real-time drug storage information, including drug name, inventory quantity, and expiration date. Various colors can be used to distinguish drug name, inventory quantity, and expiration date. For example, the expiration date is set to red to calculate the expiration date of the corresponding drug using a countdown timer.

[0047] In this embodiment, the air shower medicine cabinet system interfaces with the hospital system via a Wi-Fi module, automatically synchronizing data daily. The medicine information entry device and display screen enable digital management, reducing human error and improving medicine traceability efficiency.

[0048] Furthermore, the filtration and adsorption assembly includes a pre-filter and a high-efficiency filter, and an activated carbon filter is installed inside the exhaust duct 5. The pre-filter has a double-layer aluminum mesh structure and is installed at the front end of the filter jacket. The high-efficiency filter uses an H13-grade HEPA filter element with a glass fiber filter paper pleat spacing of 8mm, which is tightly fitted to the inner wall of the filter jacket through a silicone sealing ring. The combined design of the pre-filter, high-efficiency filter, and activated carbon filter filters particulate matter and harmful gases in stages, ensuring a high degree of air cleanliness.

[0049] Furthermore, the inner sidewall of the cabinet 1 is provided with several parallel slots, and the perforated plate 2 is engaged with the slots. The perforated plate 2 and the cabinet 1 are detachable. The slot structure facilitates the flexible installation and height adjustment of the perforated plate 2 to meet the storage needs of different drug specifications.

[0050] Furthermore, the inner sidewall and bottom wall of cabinet 1 are provided with tearable adhesive mats. The tearable adhesive mats adsorb residual dust, reduce the frequency of cleaning, and maintain a clean environment inside the cabinet. When the tearable adhesive mats are attached to the inner sidewall of cabinet 1, they are provided with perforations to avoid air supply holes.

[0051] The various embodiments of this application have been described above. These descriptions are exemplary and not exhaustive, nor are they limited to the disclosed embodiments. Many modifications and variations will be apparent to those skilled in the art without departing from the scope and spirit of the described embodiments. The terminology used herein is chosen to best explain the principles, practical application, or improvement of the technology in the market, or to enable others skilled in the art to understand the embodiments disclosed herein.
