Description

Technical Field

[0001] The invention relates to the technical field of medicine storage, and in particular to a moisture-proof storage device for pharmaceutical products. Background Art

[0002] In contemporary pharmaceutical storage practices, the proper preservation of drugs is directly related to the stability of their efficacy and the safety of patients. Many drugs, especially solid preparations such as tablets, capsules, granules and some liquid preparations, are extremely sensitive to environmental humidity. These drug ingredients are prone to absorb moisture in a high humidity environment, leading to deliquescence, agglomeration, deterioration and even failure, which seriously affects the physical and chemical properties and bioavailability of the drugs. For example, sugar-coated tablets may peel off due to moisture absorption, affecting the sustained-release mechanism of the drug; granules and powders are prone to agglomeration, making it difficult to accurately administer the drug in divided doses. In addition, humidity promotes the growth of microorganisms, increases the risk of drug contamination, and poses a potential threat to patients.

[0003] In view of this, moisture-proof storage has become an indispensable part of drug management. Traditional moisture-proof methods mostly rely on physical isolation and environmental control, among which moisture-proof storage cabinets are a widely used device. This type of equipment is generally designed with a sealed cabinet, which aims to maintain relatively stable low-humidity conditions inside by reducing the impact of the external environment on the drugs. Most of the early and existing moisture-proof storage cabinets mainly use natural or mechanical ventilation systems, trying to reduce the humidity inside the cabinet with the help of air circulation. However, when the humidity of the external environment increases significantly, such as in the rainy season or high-humidity areas, the strategy of relying solely on ventilation appears to be stretched. External moisture can penetrate into the cabinet through the vents, which not only fails to effectively dehumidify, but may aggravate the humidity inside the cabinet, which goes against the original intention of moisture-proofing. Summary of the invention

[0004] The purpose of the present invention is to provide a moisture-proof storage device for pharmaceutical supplies, which has the function of automatic dehumidification and drying, can ensure the dry storage of medicines as much as possible, and also has a refrigeration function to meet the refrigeration needs of special medicines.

[0005] The above technical objectives of the present invention are achieved through the following technical solutions: A moisture-proof storage device for pharmaceutical products, comprising a cabinet, wherein a cabinet door is hingedly connected to an open end of the cabinet, wherein the cabinet is divided from bottom to top into a general area, a refrigerated area and a dry storage area, wherein the dry storage area is provided with a plurality of storage shelves from bottom to top, wherein each storage shelf is provided with a plurality of ventilation holes near its end, and the ventilation holes on two adjacent storage shelves are staggeredly distributed at both ends;

[0006] On one side of the cabinet body, an air inlet box is provided. Inside the air inlet box, there is a condensation chamber at the upper part and a water receiving chamber at the lower part. An air inlet communicating with the condensation chamber is opened at the upper part of the air inlet box. A semiconductor refrigeration sheet is arranged in the condensation chamber. The cold end of the semiconductor refrigeration sheet faces the air inlet and is connected with a cold conducting sheet. The hot end of the semiconductor refrigeration sheet is connected with a heat sink. Both the cold conducting sheet and the heat sink are arranged vertically. The cabinet body is provided with a lower air inlet communicating the refrigeration area and the condensation chamber, and an upper air inlet communicating the dry storage area and the condensation chamber. The upper air inlet is located below the lowermost storage layer board. The ventilation holes on the lowermost storage layer board are located at one end close to the air inlet box. One side of the water receiving chamber is open, and a water receiving tank that can be drawn out from its opening is arranged inside the water receiving chamber;

[0007] On the side of the cabinet body far from the air inlet box, an exhaust box is provided. The cabinet body is provided with a lower exhaust hole communicating the refrigeration area and the exhaust box, and an upper exhaust hole communicating the dry storage area and the exhaust box. The upper exhaust hole is located above the uppermost storage layer board. An air outlet is communicated with the outside of the exhaust box, and an electric fan is installed in the air outlet.

[0008] By adopting the above technical solution, the medicines that need to be stored dry are placed on the storage layer boards in the dry storage area, and the medicines that need to be stored at low temperature are placed in the refrigeration area. Medicines or other items without storage requirements can be placed in the ordinary area. When the humidity in the dry storage area is relatively high, the electric fan is started to generate a serpentine upward climbing air flow in the dry storage area. The negative pressure generated causes air to enter the air inlet box from the air inlet. The semiconductor refrigeration sheet works to quickly cool the cold conducting sheet to a low temperature. After the air passes through the cold conducting sheet, the internal water vapor quickly condenses on the cold conducting sheet and gradually drips into the water receiving tank. Subsequently, after the dry cold air passes through the cold conducting sheet, it bypasses to the back and passes through the heat sink. The cold air absorbs the temperature on the heat sink, functioning to dissipate the heat of the heat sink. Finally, it climbs upward in a serpentine shape from the dry storage area to take away the internal moisture, and the cold air also enters the refrigeration area to lower the internal temperature, and finally is discharged through the electric fan.

[0009] A further setting of the present invention is that a temperature sensor is arranged in the refrigeration area, and a humidity sensor is arranged in the dry storage area.

[0010] A further setting of the present invention is that the side walls of the refrigeration area are all made of heat-insulating materials, and a heat-insulating layer board matching the refrigeration area is arranged on the inner side of the cabinet door.

[0011] A further setting of the present invention is that a filter screen is arranged in the air inlet.

[0012] A further setting of the present invention is that a handle is arranged on the outer wall of the water receiving tank.

[0013] A further setting of the present invention is that a blocking piece is rotatably connected below the air outlet in the exhaust box, the blocking piece can cut off the connection between the lower exhaust hole and the air outlet, one end of the blocking piece extends out of the exhaust box and is provided with a swing arm, the swing arm is parallel to the blocking piece, and an electric telescopic rod is rotatably connected between the outer wall of the exhaust box and the free end of the swing arm.

[0014] By adopting the above technical solution, it is possible to cool the refrigerated area intermittently according to requirements, avoiding continuously introducing cold air into the refrigerated area and causing the internal temperature to be too low.

[0015] A further setting of the present invention is that a protective shell for covering the swing arm and the electric telescopic rod is provided outside the exhaust box.

[0016] To sum up, the present invention has the following beneficial effects:

[0017] First, when the present invention dries and stores medicines, before ventilation and drying, the incoming air is first condensed and dehumidified to prevent the external humidity from being too high and aggravating the humidity inside the cabinet, making the present invention more suitable for use in areas with higher humidity and meeting the needs of drying and storing medicines in these areas;

[0018] Second, when the present invention condenses and dehumidifies, it can also cool the refrigerated area at the same time, enabling the present invention to also have a refrigeration function, meeting the refrigeration needs of special medicines, making the condensation and dehumidification system able to serve two purposes and meet more usage requirements;

[0019] Third, through a clever structural design, after the air is condensed and dehumidified by the cold conduction sheet, it bypasses to the heat dissipation fin to dissipate heat for the heat dissipation fin, reducing the temperature of the hot end of the semiconductor refrigeration sheet, and no additional equipment is required to cool the hot end of the semiconductor refrigeration sheet, enabling the semiconductor refrigeration sheet to work stably.

A filter screen 44 is provided in the air inlet 43 to prevent impurities in the air from being sucked into the air inlet box 4. A semiconductor refrigeration sheet 5 is provided in the condensation chamber 41. The cold end of the semiconductor refrigeration sheet 5 faces the air inlet 43 and is connected with a plurality of cold conduction sheets 51. The hot end of the semiconductor refrigeration sheet 5 is connected with a plurality of heat dissipation sheets 52. The cold conduction sheets 51 and the heat dissipation sheets 52 are all arranged vertically, so that the air can pass through the cold conduction sheets 51 and then bypass to the position of the heat dissipation sheets 52. The cabinet body 1 is provided with a lower air inlet 16 communicating the refrigeration area 12 and the condensation chamber 41, so that the cold air can enter the refrigeration area 12. The cabinet body 1 is provided with an upper air inlet 17 communicating the dry storage area 13 and the condensation chamber 41, so that the dry air can enter the dry storage area 13. The upper air inlet 17 is located below the lowermost storage layer board 14. The ventilation holes 15 on the lowermost storage layer board 14 are located at one end close to the air inlet box 4. One side of the water receiving chamber 42 is open. A water receiving tank 6 that can be drawn out from its opening is provided in the water receiving chamber 42. A handle 61 is provided on the outer wall of the water receiving tank 6. The water vapor in the air condenses and drips into the water receiving tank 6 after passing through the cold cold conduction sheets 51.

[0031] Working principle: Put the medicines that need to be stored dry on the storage shelf 14 in the dry storage area 13, put the medicines that need to be stored at low temperature in the refrigerating area 12, and put the medicines or other items without storage requirements in the ordinary area 11. When the humidity in the dry storage area 13 is relatively high, start the electric fan 72 to generate a serpentine upward climbing air flow in the dry storage area 13. The negative pressure generated makes the air enter the air inlet box 4 from the air inlet 43. The semiconductor refrigeration sheet 5 works to quickly cool the cold conduction sheet 51 to a low temperature. After the air passes through the cold conduction sheet 51, the internal water vapor quickly condenses on the cold conduction sheet 51 and gradually drips into the water receiving tank 6. Then, after the dry cold air passes through the cold conduction sheet 51, it goes around to the back and passes through the heat sink 52. The cold air absorbs the temperature on the heat sink 52, serving the function of dissipating heat for the heat sink 52. Finally, it climbs upward in a serpentine shape from the dry storage area 13 to take away the internal water vapor, and finally is discharged through the electric fan 72. When it is necessary to cool the refrigerating area 12, the telescopic electric rod 82 works to shorten and drive the blocking piece 8 to rotate, so that the lower exhaust hole 18 is communicated with the air outlet 71. The dry cold air passes through the refrigerating area 12 and gradually cools the refrigerating area 12. Finally, the cold air is also discharged through the electric fan 72. After the temperature drops to the specified temperature, control the telescopic electric rod 82 to work to extend and drive the blocking piece 8 to rotate, cutting off the connection between the lower exhaust hole 18 and the air outlet 71.
