The invention provides a medicine storage cabinet. Referring to fig. 1-8 and 10, in some embodiments, a drug storage cabinet includes a cabinet 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 body 103 has a storage cavity 204 inside, the wall 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 atmospheric environment (specifically, indirectly communicated with the atmospheric environment through some air ducts). A blower 901 is connected to the cabinet 103, the blower 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 opening 201 supplies air to leave the storage cavity 204. The flowing air may carry away some of the heat from the contents of the storage chamber 204 to regulate the temperature within the storage chamber 204 to ensure that the drug is stored in a suitable temperature environment. The tray 401 is provided in plural, and the plural trays 401 are provided at intervals in the up-down direction. Tray 401 is connected with cabinet body 103, and tray 401 sets up in storing chamber 204, and first overfire air hole 605 has been seted up to tray 401's bottom, and first overfire air hole 605 supplies the air to pass through (first overfire air hole 605 sets up to the through-hole promptly), therefore the air can pass a plurality of trays from bottom to top. The medicine cartridge 202 is installed on the upper side of the tray 401, and the medicine cartridge 202 is used for containing medicine.

Since the tray 401 is opened with the first air passing hole 605, the air flowing in the storage chamber 204 can pass through the tray 401 from the first air passing hole 605, thereby smoothly flowing through the plurality of trays 401. Therefore, the medicine storage cabinet of the invention has smooth air flow in the vertical direction, which is beneficial to improving the temperature uniformity of the storage cavity 204 in the vertical direction, thereby ensuring the storage temperature consistency of medicines in different layers.

In the above embodiments, the medicine storage cabinet has a ventilation function, but does not have a refrigeration function. In yet other embodiments, referring to fig. 1-9, the drug storage cabinet has a refrigeration function. The medicine storage cabinet with a refrigeration function includes a cabinet body 103, a fan 901, a storage unit 403 (the storage unit 403 includes a tray 401 and a medicine box 202), and a refrigeration system. Specifically, the cabinet body 103 is provided with a circulating air duct 903 and 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 circulating air duct 903. The fan 901 is connected with the cabinet 103, and the fan 901 is used for driving air to circularly flow through the air outlet 302, the storage cavity 204, the air return opening 201 and the circulating air duct 903. The tray 401 is provided with a plurality of, and a plurality of trays 401 set up along upper and lower direction interval, and tray 401 is connected with the cabinet body 103, and tray 401 sets up in storing the chamber 204. The bottom of the tray 401 is provided with a first air passing hole 605, and the first air passing hole 605 is used for air to pass through. The medicine cartridge 202 is installed on the upper side of the tray 401, and the medicine cartridge 202 is used for containing medicine. 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 in the refrigeration system are connected by piping along which refrigerant can flow (piping not specifically shown). The compressor 905 compresses a gaseous refrigerant, and after the compression, the refrigerant is in a high-temperature and high-pressure gaseous state. The high-temperature and high-pressure gaseous refrigerant enters the condenser 904 to be condensed into a liquid state. The liquid refrigerant then flows through a throttling element (which may be configured as an expansion valve or a capillary tube, and not shown) that throttles the refrigerant to reduce its pressure. The refrigerant flowing out of the throttling element enters the evaporator 902 to be evaporated, and the gaseous refrigerant enters the compressor 905 again to perform the next refrigeration cycle. The evaporator 902 is disposed in the circulating air duct 903, and the air that is going to flow through the storage chamber 204 absorbs heat from the refrigerant in the evaporator 902 in the circulating air duct 903 (the refrigerant needs to absorb heat when evaporating), and the air is blown out into the storage chamber 204 after the temperature of the air is reduced, so as to adjust the temperature in the storage chamber 204. The refrigerant needs to release heat as it flows through the condenser 904, and the heat released by the condenser 904 may be absorbed by the outside air. Referring to the figure, to ensure the cooling effect, both the compressor 905 and the condenser 904 should be in a different space from the evaporator 902, and there should be an insulating baffle (or other insulating structure) between the two spaces.

The medicine storage cabinet with the refrigeration function and the medicine storage cabinet without the refrigeration function can also improve the temperature uniformity of the storage cavity 204 along the vertical direction. Relatively speaking, the medicine storage cabinet with the refrigeration function has wider temperature regulation range and stronger applicability (especially suitable for medicines needing low-temperature storage); the medicine storage cabinet without the refrigeration function has a relatively simple structure and lower cost.

The structures of the components of the medicine storage cabinet will be described in detail below, and the structures described below can be applied to both a medicine storage cabinet having a refrigeration function and a medicine storage cabinet not having a refrigeration function.

In some embodiments, the drug storage cabinet is provided with a drug weighing function to monitor the total amount of drug in the drug storage cabinet. Specifically, the storage unit 403 further includes a load cell 501, the load cell 501 is attached to an upper side of the tray 401, the medicine cassette 202 is placed on the load cell 501, and the load cell 501 is used to measure the weight of the medicine placed in the medicine cassette 202. Note that the weight value measured by the load cell 501 is actually the sum of the weights of the medicine cassette 202 and the medicines (the medicines placed in the medicine cassette 202). However, when the medicine cassette 202 is mounted on the load cell 501, the measurement value can be set to zero, and the value obtained by placing the medicine into the medicine cassette 202 can directly reflect the weight of the medicine.

Referring to fig. 5 and 7, load cell 501 includes a deformation body 703, a first mounting seat 705, a second mounting seat 701, a load electronic control board 704, and a cover plate 702. The first installation 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 installation seats 705, and the first air passing holes 605 are provided on the area between the adjacent first installation seats 705; the top of the other end (rear end) of the deformable body 703 is connected to the second mounting base 701, and the medicine cartridge 202 is mounted on the second mounting base 701. Under the weight of the drug cassette 202 and the drug, the deformation 703 will bend, and the deformation 703 will have a strain gauge (not shown) inside, which will also bend accordingly. The strain gauge is connected with the weighing electronic control board 704 through a cable, and the deformation amount of the strain gauge changes the resistance of a measuring circuit of the weighing electronic 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 measurement circuit, and the weight of the medicine can be known from the magnitude of the output signal of the measurement circuit. This type of load cell 501, i.e., the cantilever-beam load cell 501, is highly accurate, and this type of load cell 501 and its measurement circuit are well known in the art and will not be described in further detail herein, and other types of load cells 501 may be used to achieve weighing. The cover plate 702 is connected to the front end of the first mounting seat 705 and covers the weighing electric control plate 704, and the cover plate 702 can shield the weighing electric control plate 704 from dust and water to protect the weighing electric control plate 704. In addition, the first air passing hole 605 is disposed between two adjacent first mounting seats 705, that is, the first air passing hole 605 is disposed in an area of the tray 401 not shielded by the first mounting seats 705, so that the first mounting seats 705 do not block air passing through the first air passing hole 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 arranged in the main body 101, a first medicine taking opening 301 is arranged at the front side of the main body 101, and the first medicine taking opening 301 is communicated with the storage cavity 204. Medicine enters and exits the storage chamber 204 through the first medicine-taking port 301, and the hand of the user can enter and exit the storage chamber 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 opening 301 to close the storage cavity 204, so as to protect the medicine. If the medicine is to be taken, the cabinet door 102 needs to be opened. Referring to fig. 1 to 3, the left end of the cabinet door 102 may be 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.

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. First front plate 601 is located the tray 401 and is close to one side of cabinet door 102, and first back plate 603 sets up with first front plate 601 interval, and first back plate 603 is located the tray 401 and keeps away from one side of cabinet door 102. The first bottom plate 604 is positioned at the bottom of the tray 401, and the first air passing hole 605 is 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 both connected to the first base plate 604. The number of the first side plates 602 is two, the two first side plates 602 are arranged at intervals, the bottom end of the first side plate 602 is connected with the first bottom plate 604, and the first front plate 601 and the first rear plate 603 are both connected with the first side plate 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.

To facilitate taking and placing the medicine, the tray 401 may be slidably connected to the main body 101, for example, sliding rails (not specifically shown) are disposed on two side walls of the left and right sides of the storage cavity 204, and a slider (also not shown) is mounted on the first side plate 602 of the tray 401, and is slidably disposed in the sliding rails. The tray 401 is slidable relative to the main body 101 and enters and exits the storage cavity 204 through the first medication port 301. When medicine needs to be taken, a user opens the cabinet door 102, then draws out the tray 401, and then takes out the medicine in the medicine box 202; similarly, when it is desired to dispense medication, the user first opens door 102 and withdraws tray 401, then dispenses medication into medication holder 202, and then pushes tray 401 back into storage chamber 204 and closes door 102. If the tray 401 is provided in a non-slidable manner, the space between the medicine cassette 202 and the top wall of the storage chamber 204 and the space between the medicine cassette 202 on the lower layer and the tray 401 on the upper layer are small, and it is inconvenient for a user to insert a hand to take or put medicine. If the tray 401 is configured to be slidable, the tray 401 can be drawn out of the storage cavity 204, and it is more convenient for the user to take and put the medicine.

Referring to fig. 7 and 8, the medicine cassette 202 includes a second front plate 706, a second rear plate 708, a second bottom plate 801, and a second side plate 707. Second front plate 706 is located on a side of pill box 202 near door 102, second rear plate 708 is located on a side of pill box 202 away from door 102, and second front plate 706 and second rear plate 708 are spaced apart. The second bottom plate 801 is located at the bottom of the medicine cassette 202, and the bottom ends of the second front plate 706, the second rear plate 708, and the second side plate 707 are connected to the second bottom plate 801. The second side plate 707 is 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 hole 804 also allows air to pass through in the vertical direction, and the air passes through the first air passing hole 605 of a certain tray 401 and then passes through the second air passing hole 804 of the medicine cassette 202 placed on the tray 401. That is, for the same storage unit 403, air passes through the first air passing hole 605 and the second air passing hole 804 of the storage unit 403 in sequence. The second air passing holes 804 may be provided to reduce an area of the second bottom plate 801 to which the air flowing therethrough applies force, thereby reducing the force of the air flowing in the up-down direction to the medicine cartridge 202. Therefore, the second air passing hole 804 can reduce the acting force of air flowing in the up-down direction on the medicine box 202, reduce the proportion of wind force in the external force borne by the deformation body 703 of the weighing sensor 501, and reduce the influence of wind force on the accuracy of the weighing. In addition, the second air passing holes 804 can reduce the resistance of air flowing in the storage cavity 204 along the vertical direction, so that the air can smoothly flow in the vertical direction, that is, the second air passing holes 804 are favorable for improving the temperature uniformity of the storage cavity 204 along the vertical direction, and the influence of temperature and weight precision is reduced (when the temperature in the storage cavity 204 is unbalanced, the weighing precision of the weighing sensors 501 on different layers is different). Instead of providing the second air passing holes 804, it is also conceivable to provide a larger gap between the plurality of medicine cassettes 202 on the same tray 401 for air to pass 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 dispensing port 803, and the second medicine dispensing port 803 communicates with the medicine storage space 402. The second medicine taking port 803 is convenient for the hand of the user to extend into the medicine storage space 402, thereby facilitating the taking or placing of the medicine. The medicine box 202 further includes 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 the positioning column 802 to insert, so as to realize the positioning between the medicine box 202 and the second mounting seat 701. In other embodiments, to provide the second access port 803 on the front side of the drug cassette 202, the drug cassette 202 may not include the second front plate 706. That is, the medicine cassette 202 includes the second rear plate 708, the second side plates 707 (two second side plates 707 are provided), and the second bottom plate 801, but the medicine cassette 202 does not include the 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 jointly define the second medicine taking opening 803.

The air outlet 302 is disposed on a side wall of the storage cavity 204 far from the cabinet door 102, i.e. a rear side wall of the storage cavity 204, and the air return opening 201 is disposed on a top wall of the storage cavity 204. The left and right side wall surfaces of the storage cavity 204 need to be provided with structures for installing the tray 401, and the front side of the storage cavity 204 is provided with the first medicine taking opening 301, so that the air outlet 302 is arranged on the rear side wall surface of the storage cavity 204, and the air return opening 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, a plurality of air outlets 302 are provided, and the air outlets 302 are distributed at intervals along the arrangement direction (i.e. the vertical direction) of the trays 401, so that more medicines can be directly blown by the air blown from the air outlets 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 adjacent storage units 403, and the gap is a ventilation gap 1101, and at least a portion of the air outlet 302 faces the ventilation gap 1101, so that resistance to forward flow of air is reduced, and air circulation is accelerated.
