Description

Technical Field

[0001] This utility model relates to the field of pharmaceutical storage technology, specifically to a temperature-controlled pharmaceutical storage cabinet. Background Technology

[0002] As special commodities, the quality and efficacy of pharmaceuticals are closely related to the storage environment, especially temperature. To ensure the stability of pharmaceuticals within their shelf life, specialized pharmaceutical storage cabinets are typically used, which provide a low-temperature or constant-temperature storage environment through their refrigeration systems.

[0003] For example, patent application number CN201810928697.7, entitled "An Invention Patent for a Pharmaceutical Storage Cabinet for Biopharmaceuticals," includes a cabinet body and a temperature control system. The cabinet body has a storage cavity starting in the middle, with a partition welded to the middle of the cavity. Ventilation slots are provided at the top and bottom of the cavity, and a motor is fixedly installed within each slot. A fan blade is rotatably connected to the motor's output end. Slide rails are welded to the cavity and the partition, and storage shelves are slidably mounted on these rails. Temperature and odor sensors are symmetrically installed at the top and bottom of the cavity, respectively. A cooler and a heater are installed in the middle of the cavity. This pharmaceutical storage cabinet, through its ventilation mechanism, achieves excellent ventilation, which is beneficial for the long-term preservation of pharmaceuticals. It also features a constant temperature control system to ensure a constant temperature under good ventilation conditions, thereby guaranteeing the stability of the pharmaceutical's efficacy.

[0004] However, the above solution employs a holistic cooling design. Its refrigeration system cools the entire interior space of the cabinet indiscriminately, maintaining a relatively uniform temperature throughout the storage area. However, in actual drug management, different types and dosage forms of drugs often have different optimal storage temperature requirements.

[0005] This uniform temperature control method presents significant limitations. When an institution needs to store multiple medications with different temperature requirements simultaneously, it often has to store all medications in an environment that meets the most stringent (i.e., lowest) temperature requirement. This can lead to unsuitable overcooling for some medications and unnecessary energy waste. Alternatively, the institution must purchase multiple storage cabinets set at different temperatures, which significantly increases equipment procurement costs and physical space requirements. The root cause is that existing storage cabinets generally lack an effective structure that allows for the flexible creation of multiple independent temperature zones within a single cabinet, based on specific needs.

[0006] Therefore, this utility model proposes an adjustable temperature-controlled medicine storage cabinet to address the shortcomings of the prior art. Utility Model Content

[0007] The purpose of this invention is to solve the above problems and provide an adjustable temperature-controlled medicine storage cabinet, which enables on-demand and independent zoned temperature control of the internal space of the cabinet, thereby improving the space utilization of the equipment and the quality of medicine storage.

[0008] The technical solution adopted by this utility model to solve its technical problem is: An adjustable temperature-controlled medicine storage cabinet includes a cabinet body, a sealed door hinged to the cabinet body, and medicine shelves disposed within the cabinet body. It also includes several temperature control mechanisms disposed on the side of the cabinet body, each corresponding to a specific storage space. Each temperature control mechanism includes a circulating air duct, an evaporator, and a fan disposed within the cabinet body. The temperature control mechanism further includes a closed assembly for achieving zoned temperature control. The closed assembly includes an isolation crossbeam and several isolation plates that can be opened and closed on the isolation crossbeam. Ventilation openings communicating with the circulating air duct and corresponding to the closed assembly are provided on the side wall of the cabinet body.

[0009] Furthermore, the enclosure assembly also includes a motor, a swing frame, a control rod, and a connecting block disposed at the lower end of the isolation plate; the motor is fixed on the isolation crossbar and connected to the swing frame, the swing frame is rotatably connected to one end of the control rod, and the other end of the control rod is rotatably connected to the connecting block.

[0010] Furthermore, it also includes a dehumidification mechanism, which includes a rotating plate rotatably connected to the cabinet, a dehumidification component fixed to the inside of the rotating plate, and a connecting component for unlockably locking the rotating plate.

[0011] Furthermore, the dehumidification assembly includes a dehumidification box containing a desiccant and a ventilation plate covering the opening of the dehumidification box, the ventilation plate having ventilation holes.

[0012] Furthermore, the connecting assembly includes a connecting rod rotatably mounted on the rotating plate, a bracket fixed to one end of the inner side of the connecting rod, and a locking rod fixed to the lower end of the bracket, wherein the locking rod is used to lock into the bracket in a detachable manner.

[0013] Furthermore, the connecting assembly also includes a lever, a sliding block, and a locking plate. The lever is connected to the sliding block; the sliding block is fixedly connected to the locking plate; the locking plate is fixedly connected to the locking rod; and the lever is used to drive the locking rod to separate from the locking frame.

[0014] Furthermore, the connecting assembly also includes a spring, the lower end of which is connected to the sliding block, and the upper end of which is connected to the cabinet.

[0015] The beneficial effects of this utility model are: 1. This utility model solves the problem that existing medicine storage cabinets typically have a single temperature and cannot meet the diverse and precise storage temperature requirements of different medicines by setting up a closed assembly consisting of a motor, a swing frame, a control rod, and an isolation plate.

It achieves the technical effect of conveniently and quickly removing the dehumidification component from the outside of the cabinet to replace the dehumidifier, greatly simplifying the maintenance process and improving operational safety.

[0017] 3.

[0021] To enable those skilled in the art to better understand the technical solutions of this utility model, the technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this utility model, and not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort should fall within the protection scope of this utility model.

[0022] like Figure 1 , Figure 2 , Figure 3 and Figure 4As shown, an adjustable temperature-controlled medicine storage cabinet includes a cabinet body 1, a sealed door 2 hinged to the cabinet body 1, and a medicine rack 3 disposed inside the cabinet body 1. It also includes several temperature control mechanisms 4 disposed on the side of the cabinet body 1, each corresponding to a different medicine storage space. Each temperature control mechanism 4 includes a circulating air duct 42, an evaporator 41, and a fan 44 disposed inside the cabinet body 1. The temperature control mechanism 4 also includes a closed assembly 45 for achieving zoned temperature control. The closed assembly 45 includes an isolation crossbeam 43 and several isolation plates 456 that are openable and closable on the isolation crossbeam 43. Ventilation openings 46 are provided on the side wall of the cabinet body 1, communicating with the circulating air duct 42 and corresponding to each of the closed assemblies 45. The isolation plates 456 are used to selectively open or close the ventilation openings 46. By setting up a temperature control mechanism 4 corresponding to each layer of drug storage space, the isolation plate 456 of the temperature control mechanism 4 selectively opens or closes the ventilation port 46, thereby achieving on-demand and independent zoned temperature control of the internal space of the cabinet, improving the space utilization of the equipment and the quality of drug storage.

[0023] like Figure 3 As shown, the enclosed assembly 45 also includes an isolation frame 451, a motor 452, a swing frame 453, a control rod 454, and a connecting block 455 disposed at the lower end of the isolation plate 456. The isolation plate 456 is disposed within the isolation frame 451, which is mounted on the isolation crossbar 43. The motor 452 is fixed to the isolation crossbar 43 and connected to the swing frame 453. The swing frame 453 is rotatably connected to one end of the control rod 454, and the other end of the control rod 454 is rotatably connected to the connecting block 455. The connecting block 455 is fixedly connected to the isolation plate 456. Through this multi-link transmission structure, the rotational motion of the motor 452 is precisely converted into the opening and closing action of the isolation plate 456. The isolation plate 456 is closably disposed at the ventilation opening 46 on the isolation crossbar 43, thereby selectively controlling whether the cold air in the circulating air duct 42 enters the specific storage area separated by the isolation crossbar 43, realizing on-demand zoned temperature control of the internal space of the cabinet 1.

[0024] like Figures 5 to 7As shown, the system also includes a dehumidification mechanism 5, which comprises a rotating plate 52 rotatably connected to the cabinet 1, a dehumidification component 53 fixed to the inner side of the rotating plate 52, a rotating rod 51 rotatably connected to the cabinet 1 at the lower end of the rotating plate 52, and a connecting component 54 for unlockably locking the rotating plate 52. By setting up a dehumidification mechanism consisting of a rotatable rotating plate, a dehumidification component fixed to the rotating plate, and a connecting component for locking the rotating plate, the system solves the problems of inconvenient maintenance of existing storage cabinet dehumidification devices, the need to reach inside the device to replace the desiccant, the difficulty of operation, and the hygiene risks. It achieves the technical effect of allowing convenient and quick removal of the dehumidification component from the outside of the cabinet to replace the desiccant, greatly simplifying the maintenance process and improving operational safety.

[0025] like Figure 7 As shown, the dehumidification assembly 53 includes a dehumidification box 531 containing a dehumidifier 534, and a ventilation plate 532 covering the opening of the dehumidification box 531, with ventilation holes 533 on the ventilation plate 532.

[0026] like Figure 6 As shown, the connecting assembly 54 includes a connecting rod 541 rotatably mounted on the rotating plate 52, a bracket 542 fixed to one end of the inner side of the connecting rod 541, and a locking rod 543 fixed to the lower end of the bracket 542. The locking rod 543 is used to lock into the bracket 542 in a lockable manner.

[0027] like Figure 6 As shown, the connecting assembly 54 also includes a lever 546, a sliding block 545, and a locking plate 544. The cabinet 1 has an elongated hole. The lever 546 passes through the elongated hole and slides up and down along the elongated hole. The lever 546 is connected to the sliding block 545. The sliding block 545 is fixedly connected to the locking plate 544. The locking plate 544 is fixedly connected to the locking rod 543. The lever 546 is used to drive the locking rod 543 to separate from the locking frame 542.

[0028] like Figure 6 As shown, the connecting assembly 54 also includes a spring 547, the lower end of which is connected to the sliding block 545, and the upper end of which is connected to the cabinet 1.

[0029] By designing a lever-locking mechanism consisting of a lever, sliding block, spring, and locking rod for the connecting components of the dehumidification mechanism, the problem of unstable position of movable parts during daily use and cumbersome unlocking steps during maintenance is solved. This achieves the technical effect of stable locking and convenient unlocking of the dehumidification module, enhancing the structural reliability and ease of use of the device.

[0030] In the locked state, the spring 547 pulls the sliding block 545 up, causing the locking rod 543 to engage with the bracket 542, thereby locking the rotating plate 52; when the lever 546 is moved down, the locking rod 543 separates from the bracket 542. At this time, rotating the connecting rod 541 can drive the rotating plate 52 to rotate outward and open, bringing the dehumidifying component 53 fixed on it out of the cabinet 1, realizing the quick replacement of the dehumidifier 534 without contacting the inside of the equipment.

[0031] The working principle is as follows: When a specific area within cabinet 1 requires cooling, the motor 452 on the corresponding area isolation frame 43 starts. The motor 452 drives the swing frame 453 to swing through the transmission connection. The swing frame 453 then drives the isolation plate 456 to open the ventilation port 46 through the control rod 454 and the connecting block 455 connected by rotation. At the same time, the fan 44 starts, blowing the air cooled by the evaporator 41 in the circulating air duct 42 into the designated area through the opened ventilation port 46 for cooling. The air that has completed heat exchange then flows out from the ventilation port 46 on the other side and returns to the circulating air duct 42 to enter the next cooling cycle. Through the synergistic effect of this closed component 45, independent and precise temperature control of different drug storage areas is achieved.

[0032] When it is necessary to replace the dehumidifier 534 in the dehumidifier assembly 53, the operator presses the lever 546 from the outside. The lever 546 drives the sliding block 545, the locking plate 544, and the locking rod 543 in a coordinated manner, causing the locking rod 543 to disengage from the locking state with the bracket 542 and releasing the lock on the rotating plate 52. Then, by rotating the connecting rod 541, the rotating plate 52 can be rotated outward, bringing the dehumidifier assembly 53 fixed on it out of the cabinet 1 as a whole, so that the operator can easily replace it. After the replacement is completed, the operation is reversed. The restoring force of the spring 547 will cause the locking rod 543 to re-lock with the bracket 542. Through the synergistic effect of the connecting assembly 54, this utility model solves the problem of cumbersome and inconvenient operation of dehumidifier replacement in the prior art.
