The invention provides a medicine storage cabinet. Referring to fig. 1-8 and 10, in some embodiments, the drug storage cabinet includes a cabinet body 103, a blower 901, and a storage unit 403, wherein the storage unit 403 includes a tray 401 and a drug cassette 202. Referring to fig. 2 and 3, the cabinet 103 has a storage cavity 204 inside, the wall surface of the storage cavity 204 is provided with an air outlet 302 and an air return opening 201, the air outlet 302 and the air return opening 201 are both communicated with the storage cavity 204, and the air outlet 302 and the air return opening 201 are both communicated with the atmosphere (specifically, may be indirectly communicated with the atmosphere through some air channels). The fan 901 is connected with the cabinet 103, and the fan 901 is used for driving air to circulate between the atmosphere and the storage cavity 204, wherein the air outlet 302 supplies air to enter the storage cavity 204, and the air return 201 supplies air to leave the storage cavity 204. The flowing air may remove some of the heat from the contents of the storage chamber 204 to regulate the temperature within the storage chamber 204 and ensure that the drug is stored in a suitable temperature environment. The plurality of trays 401 are provided, and the plurality of trays 401 are arranged at intervals in the up-down direction. The tray 401 is connected with the cabinet 103, and the tray 401 is disposed in the storage cavity 204, the bottom of the tray 401 is provided with a first air through hole 605, and the first air through hole 605 is used for air to pass through (i.e. the first air through hole 605 is set as a through hole), so that air can pass through a plurality of trays from bottom to top. The medicine box 202 is mounted on the upper side of the tray 401, and the medicine box 202 is for accommodating medicines.

Since the tray 401 is provided with the first air passing holes 605, air flowing in the storage chamber 204 can pass through the tray 401 from the first air passing holes 605, thereby smoothly flowing through the plurality of trays 401. Therefore, the medicine storage cabinet provided by the invention has the advantages that the air flows smoothly along the up-down direction, which is beneficial to improving the temperature uniformity of the storage cavity 204 along the up-down direction, so that the consistency of the storage temperatures of medicines in different layers is ensured.

In the above embodiment, the medicine storage cabinet has a ventilation function, but does not have a refrigeration function. In yet other embodiments, and referring to fig. 1-9, the drug storage cabinet has a refrigeration function. The medicine storage cabinet with the refrigerating function includes a cabinet body 103, a blower 901, a storage unit 403 (the storage unit 403 includes a tray 401 and a medicine box 202), and a refrigerating system. Specifically, the cabinet 103 is provided with a circulation air duct 903 and a storage cavity 204, the wall surface of the storage cavity 204 is provided with an air outlet 302 and an air return opening 201, the air outlet 302 and the air return opening 201 are both communicated with the storage cavity 204, and the air outlet 302 and the air return opening 201 are both communicated with the circulation air duct 903. The fan 901 is connected with the cabinet body 103, and the fan 901 is used for driving the air circulation to flow through the air outlet 302, the storage cavity 204, the return air inlet 201 and the circulation air duct 903. The tray 401 is provided in plurality, the plurality of trays 401 are arranged at intervals in the up-down direction, the tray 401 is connected with the cabinet 103, and the tray 401 is arranged in the storage cavity 204. The tray 401 has a first air hole 605 formed in the bottom thereof, and the first air hole 605 is for air to pass through. The medicine box 202 is mounted on the upper side of the tray 401, and the medicine box 202 is for accommodating medicines. The refrigeration system includes a refrigerant, a compressor 905, a condenser 904, a throttling element, and an evaporator 902, the refrigerant being capable of circulating through the compressor 905, the condenser 904, the throttling element, and the evaporator 902.

The components of the refrigeration system are connected by piping along which a refrigerant can flow (piping not specifically shown). The compressor 905 compresses a gaseous refrigerant, and the state of the compressed refrigerant is a high-temperature high-pressure gaseous state. The high temperature and high pressure gaseous refrigerant enters the condenser 904 to condense into a liquid state. The liquid refrigerant then flows through a throttling element (which may be provided as an expansion valve or capillary tube, the throttling element not being shown in the figure) which throttles the refrigerant to reduce the pressure of the refrigerant. The refrigerant exiting the throttling element is vaporized in the evaporator 902 and the gaseous refrigerant is again passed to the compressor 905 for the next refrigeration cycle. The evaporator 902 is disposed in the circulation duct 903, and air flowing through the storage chamber 204 absorbs heat (the refrigerant needs to absorb heat when evaporating) in the evaporator 902 in the circulation duct 903, and the air is blown out into the storage chamber 204 after the temperature of the air is reduced, so as to regulate the temperature in the storage chamber 204. Heat release is required when the refrigerant flows through the condenser 904, and the heat released from the condenser 904 can be absorbed by the outside air. Referring to the figure, to ensure a cooling effect, both the compressor 905 and the condenser 904 should be in different spaces from the evaporator 902, and there should be a thermally insulating barrier (or other thermally insulating structure) between the two spaces.

The medicine storage cabinet having the refrigerating function and the medicine storage cabinet not having the refrigerating function can also improve the temperature uniformity of the storage chamber 204 in the up-down direction. Relatively speaking, the medicine storage cabinet with the refrigerating function has wider temperature adjustment range and stronger applicability (is particularly suitable for medicines needing low-temperature storage); the medicine storage cabinet without the refrigeration function is relatively simple in structure and lower in cost.

The structures of the components of the medicine storage cabinet are described in detail below, and the structures described below are applicable to medicine storage cabinets having a refrigerating function and medicine storage cabinets not having a refrigerating function.

In some embodiments, the drug storage bin is provided with a function of weighing the drug in order to monitor the total amount of drug in the drug storage bin. Specifically, the storage unit 403 further includes a load cell 501, the load cell 501 being connected to the upper side of the tray 401, the medicine cartridge 202 being placed on the load cell 501, the load cell 501 being for measuring the weight of the medicine placed in the medicine cartridge 202. The weight value measured by the load cell 501 is actually the sum of the weight of the medicine box 202 and the weight of the medicine (medicine placed in the medicine box 202). However, after the medicine box 202 is mounted on the load cell 501, the measured value at this time may be set as zero point, and then the value obtained by placing the medicine in the medicine box 202 may directly reflect the weight of the medicine.

Referring to fig. 5 and 7, load cell 501 includes a contoured body 703, a first mount 705, a second mount 701, a load cell plate 704, and a cover plate 702. The first mounting seats 705 are connected to the top surface of the first bottom plate 604 of the tray 401, the bottom of one end (front end) of the deformation body 703 is connected to the first mounting seats 705, and the first air passing holes 605 are arranged in the area between the adjacent first mounting seats 705; the top of the other end (rear end) of the variant 703 is connected to the second mount 701, and the cartridge 202 is mounted on the second mount 701. Under the action of gravity of the medicine cartridge 202 and the medicine, the deformation body 703 is bent, and the strain gauge (not shown) is provided inside the deformation body 703, so that the strain gauge is bent. The strain gauge is connected with the weighing electric control board 704 through a cable, and the deformation amount of the strain gauge can change the resistance of a measuring circuit of the weighing electric control board 704, so that the output signal (voltage or current output) of the measuring circuit is changed. That is, the weight of the medicine determines the output signal of the measuring circuit, and the weight of the medicine can be obtained by the magnitude of the output signal of the measuring circuit. The weighing cell 501 in this form, i.e. the cantilever-type weighing cell 501, has a high accuracy, the weighing cell 501 in this form and its measuring circuit are well known in the art, and not described in further detail here, other forms of weighing cell 501 may be used for weighing. The cover plate 702 is connected with the front end of the first mounting seat 705 and covers the upper portion of the weighing electronic control board 704, and the cover plate 702 can shield the weighing electronic control board 704 from dust and water so as to protect the weighing electronic control board 704. In addition, the first through-air holes 605 are disposed between two adjacent first mounting seats 705, that is, the first through-air holes 605 are disposed in the area of the tray 401 not shielded by the first mounting seats 705, so that the first mounting seats 705 prevent air from passing through the first through-air holes 605.

Referring to fig. 1 to 3, the cabinet 103 includes a main body 101 and a cabinet door 102. The storage cavity 204 is disposed in the main body 101, and a first medicine taking port 301 is formed in the front side of the main body 101, and the first medicine taking port 301 is communicated with the storage cavity 204. The medicine enters and exits the storage cavity 204 through the first medicine taking port 301, and the hand of the user can also enter and exit the storage cavity 204 through the first medicine taking port 301. The cabinet door 102 is rotatably connected with the main body 101, and the cabinet door 102 can cover the first medicine taking port 301 to close the storage cavity 204 so as to protect medicines. To access the medication, the door 102 needs to be opened. Referring to fig. 1 to 3, specifically, the left end of the cabinet door 102 is rotatably connected to the main body 101, and when a user opens or closes the door, the user holds the right end of the cabinet door 102 and rotates the right end of the cabinet door 102 around the left end thereof.

Referring to fig. 6, the tray 401 includes a first front plate 601, a first rear plate 603, a first bottom plate 604, and a first side plate 602. The first front plate 601 is located on one side of the tray 401 close to the cabinet door 102, the first rear plate 603 is arranged at intervals with the first front plate 601, and the first rear plate 603 is located on one side of the tray 401 far away from the cabinet door 102. The first bottom plate 604 is positioned at the bottom of the tray 401, and the first through-air holes 605 are formed in the first bottom plate 604; the bottom end of the first front plate 601 and the bottom end of the first rear plate 603 are connected to the first bottom plate 604. The first side plates 602 are arranged in two, two first side plates 602 are arranged at intervals, the bottom ends of the first side plates 602 are connected with the first bottom plate 604, and the first front plate 601 and the first rear plate 603 are connected with the first side plates 602. The first front plate 601 is mainly used for mounting the display 203 (the display 203 will be described later), the first side plate 602 is used for connecting with the main body 101, and the first bottom plate 604 is used for carrying the load cell 501 and the medicine box 202.

For convenience of taking and placing medicine, the tray 401 may be slidably connected to the main body 101, for example, sliding rails (not specifically shown) are disposed on the left and right side walls of the storage cavity 204, and a slider (not shown) is mounted on the first side plate 602 of the tray 401 and slidably disposed in the sliding rails. The tray 401 is slidable relative to the body 101 and moves into and out of the storage cavity 204 through the first access port 301. When medicine is required to be taken, a user firstly opens the cabinet door 102, then withdraws the tray 401, and then takes out the medicine in the medicine box 202; similarly, when dispensing is desired, the user opens the door 102 and withdraws the tray 401, then places the drug into the case 202, and then pushes the tray 401 back into the storage cavity 204 and closes the door 102. If the tray 401 is provided in a non-slidable form, the space between the medicine cartridge 202 and the top wall of the storage chamber 204, the space between the medicine cartridge 202 of the lower layer and the tray 401 of the upper layer is small, and it is inconvenient for the user to insert his or her hand for taking or putting medicine. If the tray 401 is slidably disposed, the tray 401 can be drawn out of the storage cavity 204, so that the user can take and put medicine more conveniently.

Referring to fig. 7 and 8, the cartridge 202 includes a second front panel 706, a second rear panel 708, a second bottom panel 801, and a second side panel 707. The second front plate 706 is located on a side of the medicine box 202 near the cabinet door 102, the second rear plate 708 is located on a side of the medicine box 202 remote from the cabinet door 102, and the second front plate 706 and the second rear plate 708 are spaced apart. The second bottom panel 801 is positioned at the bottom of the cartridge 202 and the bottom ends of the second front panel 706, the second rear panel 708, and the second side panel 707 are all connected to the second bottom panel 801. The second side plates 707 are provided in two, two second side plates 707 are provided at intervals, and the second front plate 706 and the second rear plate 708 are connected to the second side plates 707. The second front plate 706, the second rear plate 708, the second bottom plate 801 and the second side plate 707 enclose a medicine storage space 402, the medicine storage space 402 is used for accommodating medicines, and the second bottom plate 801 is used for carrying medicines.

Referring to fig. 8, the second bottom plate 801 is further provided with a second air passing hole 804, the second air passing hole 804 is a through hole, and the second air passing hole 804 is communicated with the medicine storage space 402. The second air passing holes 804 are also used for air to pass through in the up-down direction, and the air passes through the first air passing holes 605 on one tray 401 and then passes through the second air passing holes 804 of the medicine boxes 202 placed on the tray 401. That is, for the same storage unit 403, air passes through the first and second air passing holes 605 and 804 of that storage unit 403 sequentially. The provision of the second through-air holes 804 can reduce the area of the second bottom plate 801 to which the flowing air applies a force, thereby reducing the force of the air flowing in the up-down direction on the medicine cartridge 202. Therefore, the provision of the second wind-passing holes 804 can reduce the force of the air flowing in the up-down direction on the medicine box 202, and reduce the ratio of the wind force to the external force received by the deformation body 703 of the load cell 501, thereby reducing the influence of the accuracy of the wind force symmetry. In addition, the provision of the second air passing holes 804 can reduce the resistance of the air flowing in the up-down direction in the storage cavity 204, so that the air can smoothly flow in the up-down direction, that is, the provision of the second air passing holes 804 is beneficial to improving the temperature uniformity of the storage cavity 204 in the up-down direction, and reducing the influence of the temperature symmetry and the weighing accuracy (when the temperature in the storage cavity 204 is unbalanced, the weighing accuracy of the weighing sensors 501 in different layers will be different). If the second ventilation holes 804 are not provided, it is also conceivable to set the gaps between the plurality of cartridges 202 on the same tray 401 to be larger so that air passes through.

Referring to fig. 8, the top end of the second front plate 706 is recessed with respect to the top end of the second side plate 707 to form a second medicine taking port 803, and the second medicine taking port 803 communicates with the medicine storage space 402. The second medicine taking port 803 facilitates the hand of the user to extend into the medicine storage space 402, thereby facilitating medicine taking or medicine placing. The medicine box 202 further comprises a positioning column 802, the positioning column 802 is connected to the bottom side of the bottom plate, the second mounting seat 701 is provided with a positioning hole 709, and the positioning hole 709 is used for inserting the positioning column 802, so that positioning between the medicine box 202 and the second mounting seat 701 is achieved. In other embodiments, the cartridge 202 may not include the second front plate 706 in order to provide the second access 803 on the front side of the cartridge 202. That is, the cartridge 202 includes a second rear plate 708, a second side plate 707 (two second side plates 707 are provided) and a second bottom plate 801, but the cartridge 202 does not include a second front plate 706, and the front ends of the second rear plate 708 and the front ends of the two second side plates 707 define a second medicine taking port 803 together.

The air outlet 302 is disposed on a side wall surface of the storage chamber 204 away from the cabinet door 102, i.e. a rear side wall surface of the storage chamber 204, and the air return opening 201 is disposed on a top wall of the storage chamber 204. The left and right side wall surfaces of the storage cavity 204 need to be provided with a structure for installing the tray 401, and the front side of the storage cavity 204 is provided with the first medicine taking port 301, so that the air outlet 302 is arranged on the rear side wall surface of the storage cavity 204, and the air return port 201 is arranged on the top wall of the storage cavity 204, thereby being beneficial to reducing layout conflicts among the structures.

Referring to fig. 9 to 11, the air outlet 302 is provided in plurality, and the plurality of air outlets 302 are spaced apart along the arrangement direction (i.e., the up-down direction) of the tray 401, so that more medicines can be directly blown by the air blown out from the air outlet 302, and the medicines on different trays 401 can be effectively cooled. Referring to fig. 11, in some embodiments, a gap is formed between two storage units 403 adjacent to each other, the gap is a ventilation gap 1101, at least a portion of the air outlet 302 faces the ventilation gap 1101, so as to reduce the resistance of forward air flow and accelerate air circulation. More specifically, for two vertically adjacent storage units 403, the gap between the bottom of the tray 401 of the upper storage unit 403 and the top of the medicine cartridge 202 of the lower storage unit 403 is a ventilation gap.

Referring to fig. 9 and 10, the top wall of the storage cavity 204 includes a return air portion 906, the return air opening 201 is formed on the return air portion 906, the return air portion 906 is obliquely disposed, and one end (i.e., front end) of the return air portion 906, which is close to the cabinet door 102, is higher than one end (i.e., rear end) of the return air portion 906, which is far from the cabinet door 102. In this arrangement, the return air inlet 201 is disposed downward and forward with respect to the return air inlet 201, and the flow path of the air after entering the circulation duct 903 (or the duct for discharging the air to the atmosphere) from the return air inlet 201 is less tortuous and the flow resistance is less.
