As shown in fig. 7, the casing 101 has a first receiving cavity 701, and the drawer main body 102 is disposed in the first receiving cavity 701; the drawer main body 102 has a second receiving chamber 702, and a medicine cartridge 305 for storing medicine is disposed in the second receiving chamber 702; the refrigeration device is also mounted inside the casing 101, but outside the first accommodation chamber 701.

Referring to fig. 1, a casing 101 is slidably coupled to a drawer main body 102, and a portion of the drawer main body 102 may be drawn out to the outside of the casing 101. For example, the wall surface of the first receiving cavity 701 has a slide rail, and a pulley is mounted on the drawer body 102, and the pulley is disposed in the slide rail (the pulley and the slide rail are not specifically shown), so that the drawer body 102 can slide relative to the casing 101. Referring to fig. 1, the housing 101 has an escape opening 103 communicating with the first accommodation chamber 701, and the drawer main body 102 can enter and exit the first accommodation chamber 701 through the escape opening 103. The user can draw the drawer main body 102 out of the avoiding opening 103 and carry out subsequent operation of taking medicine or storing medicine; after the medicine is taken or stored, the user pushes the drawer main body 102 back into the first accommodating chamber 701 from the escape opening 103.

The refrigerating device is used for refrigerating air and driving the air to flow. An end wall surface of the first accommodating cavity 701 far away from the avoiding opening 103 is provided with an air outlet 801 and an air return opening 802, for example, with reference to fig. 1, fig. 6 and fig. 8, the avoiding opening 103 is located at a front end of the first accommodating cavity 701, and a rear end wall surface of the second accommodating cavity 702 is provided with the air outlet 801 and the air return opening 802. Cold air enters the first accommodating chamber 701 through the air outlet 801, the cooling air cools the medicine and returns to the refrigeration device from the air return 802, the refrigeration device cools the air returning from the air return 802 again, and then the air is blown out from the air outlet 801 again, and the air circulates in the refrigeration drawer 100 in this way.

Referring to fig. 3 and 4, the drawer body 102 has a first vent 306, the first vent 306 being located at an end of the drawer body 102 proximate to the outlet 801, e.g., the first vent 306 is located at a rear end of the drawer body 102. Referring to fig. 5, the medicine cartridge 305 has a third ventilation opening 503 and a fourth ventilation opening 501, the third ventilation opening 503 is located at one end of the drawer body 102 near the ventilation opening 801 (for example, the third ventilation opening 503 is located at the rear end of the medicine cartridge 305), and the fourth ventilation opening 501 is located at the top of the drawer body 102.

Air circulates through the outlet 801, the first air vent 306, the third air vent 503, the fourth air vent 501, and the return air vent 802. With reference to fig. 7, cold air blown into the first accommodating cavity 701 from the air outlet 801 can enter the second accommodating cavity 702 of the drawer body 102 from the first air vent 306, and then be blown into the medicine storage box 305 through the third air vent 503 to cool the medicine in the medicine storage box 305; subsequently, the cool air flows out of the medicine tank 305 from the fourth air inlet 501, and flows to the return air inlet 802, and then returns to the refrigeration apparatus.

The utility model provides a cold-stored drawer 100, first vent 306 that drawer main part 102 supplies cold wind to pass through sets up the one end that is close to air outlet 801 and return air inlet 802 in drawer main part 102, third vent 503 that drug storage box 305 supplies cold wind to pass through sets up the one end that is close to air outlet 801 and return air inlet 802 at drug storage box 305, drug storage box 305's top and drug storage box 305 are provided with the fourth vent 501 that supplies cold wind to pass through, therefore, cold wind blows off and flows back to the tortuous degree in route of return air inlet 802 from air outlet 801 lower, the route is also shorter, therefore, cold wind's flow resistance is less in cold-stored drawer 100, cold wind's velocity of flow is higher, this is favorable to improving the cooling effect to the medicine.

The air outlet 801 and the air return 802 may be arranged at intervals in the height direction of the housing 101. For example, referring to fig. 8, in some embodiments, the air return 802 is disposed above the air outlet 801. In this arrangement, the cool air blown out from the air outlet 801 first enters the rear end of the drawer main body 102, then emerges from the top of the medicine storage box 305, and finally flows back to the air return opening located above the air outlet 801.

Alternatively, in other embodiments, the air outlet 801 may be disposed above the air return 802, for example, by adjusting the rotation direction of an impeller of a fan 1005 for driving the air flow in the refrigeration device, so that the air outlet 801 in fig. 8 is adjusted to the air return 802, and the air return 802 in fig. 8 is adjusted to the air outlet 801. In this case, the cool air is blown out from the upper outlet port 801 to above the drawer main body 102, and then flows into the medicine storage box 305 from the fourth outlet port 501 at the top of the medicine storage box 305; then, the cool air flows backward and flows through the third ventilation opening 503 and the first ventilation opening 306 in order, and finally flows back to the return air opening 802 located below the air outlet 801. In the case that the air outlet 801 is located above the air return opening 802, "air circulates through the air outlet 801, the first ventilation opening 306, the third ventilation opening 503, the fourth ventilation opening 501, and the air return opening 802", specifically, air circulates through the air outlet 801, the fourth ventilation opening 501, the third ventilation opening 503, the first ventilation opening 306, and the air return opening 802 in sequence.

Under the condition that the air outlet 801 and the air return opening 802 are arranged at intervals along the height direction of the shell 101, the relative position relationship (vertical distribution) between the first ventilation opening 306 and the fourth ventilation opening 501 is matched with the relative position relationship between the air outlet 801 and the air return opening 802, which is also beneficial to reducing the tortuosity of a path that cold air is blown out from the air outlet 801 and flows back to the air return opening 802, thereby reducing the flow resistance of the cold air and improving the flow rate of the cold air.

The structure of the refrigerating apparatus will be described below. In some embodiments, the refrigeration device cools the air by way of vapor compression refrigeration; compare in cooling down the air through semiconductor refrigeration piece, vapor compression's refrigerating plant's refrigerating output is bigger, and refrigeration effect is better. Referring to fig. 9, the refrigerating apparatus includes a compressor 1001, an evaporator 1004, a throttle 1003, a condenser 1002, a fan 1005, and a refrigerant (the refrigerant is not specifically shown).

The evaporator 1004 and the condenser 1002 may be each provided as a finned heat exchanger, the compressor 1001 may be provided as a scroll compressor 1001, a rotor compressor 1001, or the like, and the throttle 1003 may be provided as an electronic expansion valve or a capillary tube.

Referring to fig. 9, an inlet end of a compressor 1001 is connected to an outlet end of an evaporator 1004, an outlet end of the compressor 1001 is connected to an inlet end of a condenser 1002, an outlet end of the condenser 1002 is connected to an inlet end of a throttle 1003, and an outlet end of the throttle 1003 is connected to an inlet end of the evaporator 1004. Here, the connection between the inlet end of one component and the outlet end of another component is, in particular, made by means of a tube (for example, a copper tube connection), through which the refrigerant can flow, thus being transferred between the different components.

The compressor 1001 serves to compress a refrigerant in a gaseous state, and circulates the refrigerant through the compressor 1001, the condenser 1002, the throttle 1003, and the evaporator 1004 in this order (as shown in fig. 9). The compressed high-temperature and high-pressure gaseous refrigerant then enters the condenser 1002, and is condensed to release heat, and at least part of the refrigerant is converted into a liquid state. The refrigerant from the condenser 1002 passes through the throttle 1003, and the pressure of the refrigerant is reduced by the throttle action of the throttle 1003. The low pressure refrigerant then enters the evaporator 1004 where the liquid refrigerant evaporates; the evaporated gaseous refrigerant is re-introduced into the compressor 1001, thereby performing the next cycle. A fan 1005 is disposed adjacent to the evaporator 1004, and when an impeller of the fan 1005 rotates, air flows through the evaporator 1004, and refrigerant evaporated in the evaporator 1004 absorbs heat of the air, thereby reducing the temperature of the air. The low-temperature air is blown out from the outlet 801 into the first accommodation chamber 701 by the driving of the fan 1005, and the air returned from the return air inlet 802 flows toward the evaporator 1004.

Referring to fig. 10, in some embodiments, the refrigeration drawer 100 further includes insulation 1006, the condenser 1002 and the evaporator 1004 are located on different sides of the insulation 1006, respectively, and the compressor 1001 and the condenser 1002 are located on the same side of the insulation 1006. Condenser 1002 can release heat to the air, compressor 1001 can also generate heat when running, and the two heat generating components are separated from evaporator 1004 by heat insulation member 1006, which is beneficial to reducing the influence of the heat of condenser 1002 and compressor 1001 on evaporator 1004 and improving the refrigerating effect of the refrigerating device. The position of the throttling element 1003 is flexible, and the throttling element 1003 can be positioned on the same side of the heat insulation member 1006 as the evaporator 1004, can be positioned on the same side of the heat insulation member 1006 as the condenser 1002, and can even be wrapped in the heat insulation member 1006.

Figure 10 shows the general distribution of some of the components of the refrigeration unit. Referring to fig. 10, the casing 101 further has an insulating chamber 601, a third accommodating chamber 602, and a fourth accommodating chamber 604; among them, an insulation member 1006 is disposed in the insulation chamber 601, an evaporator 1004 and a fan 1005 are disposed in the third accommodation chamber 602, and a condenser 1002 and a compressor 1001 are disposed in the fourth accommodation chamber 604. A portion of the second receiving chamber 702 is located between the third receiving chamber 602 and the fourth receiving chamber 604 such that the thermal insulation 1006 is disposed between the third receiving chamber 602 and the fourth receiving chamber 604.

The copper pipe through which the refrigerant flows may penetrate the wall surfaces of the second accommodating chamber 702, the third accommodating chamber 602, and the fourth accommodating chamber 604, and may penetrate the heat insulating member 1006. Referring to fig. 6, the casing 101 may further have a heat dissipation port 605, and air may enter and exit the fourth receiving chamber 604 through the heat dissipation port 605 so that the condenser 1002 and the compressor 1001 dissipate heat. It should be noted that the air in the fourth accommodating chamber 604 mainly circulates and exchanges with the air in the external atmosphere, and the air in the fourth accommodating chamber 604 does not enter the third accommodating chamber 602 nor the first accommodating chamber 701.

The drug reservoir 305 may be provided with more vents to increase the flow of air through the interior of the drug reservoir 305 and thereby increase the cooling of the drug. For example, referring to fig. 5, at least one of an end of the drug storage box 305 facing away from the air outlet 801, a bottom end of the drug storage box 305, and an end of the drug storage box 305 in the second horizontal direction has a fifth ventilation opening 502, an inner cavity of the drug storage box 305 is a storage cavity, and the storage cavity and the second accommodating cavity 702 can be communicated through the fifth ventilation opening 502.

The sliding direction of the drawer main body 102 relative to the housing 101 is a first horizontal direction, and the second horizontal direction is perpendicular to the first horizontal direction. For example, the drawer body 102 can slide back and forth, with the first horizontal direction corresponding to the front-to-back direction and the second horizontal direction corresponding to the left-to-right direction; at least one of the front end, the bottom end, the left end, and the right end of the cartridge 305 has a fifth ventilation opening 502.

Similarly, in order to increase the air flow through the drawer main body 102 and thus increase the cooling effect on the medicine, more ventilation openings may be opened in the drawer main body 102. For example, referring to fig. 3 and 4, at least one of the bottom end, the left end, and the right end of the drawer main body 102 has a sixth ventilation opening 303, and the first receiving chamber 701 and the second receiving chamber 702 may communicate through the sixth ventilation opening 303.

Referring to fig. 3, the drawer body 102 includes a frame 301 and a cover 302, wherein the cover 302 is movably connected to the top of the frame 301, for example, the cover 302 is rotatably connected to the frame 301. The cover plate 302 and the frame 301 define a second accommodating chamber 702, and the cover plate 302 covers the medicine storage box 305 to improve the protection effect of the refrigeration drawer 100 on the medicine. When it is desired to take or deposit a drug, the cover 302 may be opened and the drug may be removed from the drug reservoir 305 or placed in the drug reservoir 305. With reference to fig. 3 and 4, the first ventilation opening 306 may be disposed at an end of the frame 301 close to the air outlet 801, so as to facilitate air to pass through the top of the drawer main body 102, and the cover plate 302 may further be disposed with a second ventilation opening 304, where the second ventilation opening 304 is communicated with the second accommodating cavity 702; the sixth vent 303 may be provided on the frame 301. In other embodiments, the drawer body 102 may not be provided with the cover 302 and the second ventilation opening 304, the top of the medicine storage box 305 is higher than the frame 301 or is flush with the top end of the frame 301, and the cool air flows out of the medicine storage box 305 and directly flows into the first accommodating cavity 701 and then flows to the ventilation opening 802.

In some embodiments, to avoid the air at the air outlet 801 and the air return 802 interfering with each other and affecting the cooling effect on the medicine, a partition may be provided at the air outlet 801 and the air return 802. For example, referring to fig. 7 and 8, the housing 101 includes a grill 704 and a partition 705, the air outlet 801 and the air return 802 are both disposed on the grill 704, and the partition 705 is connected to the grill 704 and disposed between the air outlet 801 and the air return 802. The grill 704 has a first surface and a second surface opposite to each other, wherein the first surface is a part of a wall surface of the second accommodating chamber 702, and the second surface faces the evaporator 1004 and the fan 1005, and taking fig. 8 as an example, a front side surface of the grill 704 is the first surface, and a rear side surface of the grill 704 is the second surface. A partition 705 is provided through the grill 704, a part of the partition 705 protrudes with respect to the first surface, another part of the partition 705 protrudes with respect to the second surface, and the partition 705 serves to separate two airflows at the air outlet 801 and the air return 802.

The air flow flowing from the evaporator 1004 to the first accommodating cavity 701 is recorded as air outlet, the air flow flowing back to the evaporator 1004 from the first accommodating cavity 701 is recorded as air return, the temperature of the air outlet is relatively low, the temperature of the air return is relatively high, under the condition that the partition 705 is arranged, the mutual interference between the air return and the air outlet is small based on the blocking effect of the partition 705, the influence of the air return on the temperature of the air outlet is favorably prevented, the air outlet is ensured to be at a low temperature, and the cooling effect on medicines is improved.

To enhance the cooling effect on the pharmaceutical product, in some embodiments, the refrigeration drawer 100 also has insulation 1006. Specifically, referring to fig. 6, the housing 101 has an insulating chamber 601, the insulating chamber 601 is separated from the second receiving chamber 702 (they are not directly connected), the insulating chamber 601 is disposed at the periphery of the second receiving chamber 702, and the insulating member 1006 is disposed in the insulating chamber 601 such that the insulating member 1006 surrounds a portion of the drawer main body 102. Due to the heat insulation effect of the heat insulation member 1006, the heat exchange resistance between the external environment and the drawer main body 102 is increased, and the temperature of the external environment has a smaller influence on the temperature of the medicine in the medicine storage box 305, which is beneficial to improving the cooling effect of the refrigeration drawer 100 on the medicine. Referring to fig. 6 and 10, in some embodiments, the thermal insulation member 1006 disposed in the thermal insulation chamber 601 can insulate the medicine in the drawer body 102 and can separate the evaporator 1004 and the condenser 1002.
