DETAILED DESCRIPTION

[0026] The technical scheme in the embodiments of the utility model will be described clearly and completely below with reference to the drawings in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by those skilled in the art without creative labor fall within the scope of protection of the utility model.

[0027] Please refer to Figures 1-4 The utility model provides a technical scheme: a novel portable insulin injection pen refrigeration device, including heat preservation cylinder 1, including,

[0028] Multiple storage cylinders 201 are connected in the heat preservation cylinder 1 and are distributed in a circular array at equal intervals with the axis of the heat preservation cylinder 1 as the center.

[0029] Semiconductor refrigeration part 202 is connected in the heat preservation cylinder 1, and its refrigeration end is mutually adhered with the storage cylinder 201 for refrigerating insulin.

[0030] Heat dissipation plate 203 is connected in the heat preservation cylinder 1, and one side thereof is mutually adhered with the heat dissipation end of the semiconductor refrigeration part 202.

[0031] Heat dissipation fan 204 is connected in the heat preservation cylinder 1 and is connected with the side of the heat dissipation plate 203 away from the semiconductor refrigeration part 202.

[0032] In actual implementation, when in normal use, the injection pen to be cooled can be placed in the storage cylinder 201 for storage, and at the same time, when the temperature rises, heat is transferred from the insulin injection pen and the surrounding air in the storage cylinder 201 to the refrigeration end of the semiconductor refrigerating device 202, thereby reducing the temperature in the storage cylinder 201 to achieve the cold storage of the insulin. Since the plurality of storage cylinders 201 are distributed at equal intervals in a circumferential array in the heat preservation cylinder 1, the semiconductor refrigerating device 202 can simultaneously refrigerate the plurality of storage cylinders 201, ensuring that the insulin at each position can be in a suitable low-temperature environment. The heat generated by the semiconductor refrigerating device 202 is conducted through the heat dissipation plate 203 which is attached to the heat dissipation end. The heat dissipation fan 204 is connected to the side of the heat dissipation plate 203 away from the semiconductor refrigerating device 202. When the heat dissipation fan 204 is started, it will promote air flow to ensure that the semiconductor refrigerating device 202 can work continuously and stably.

[0033] Referring to Figure 4 The storage cylinder 201 is connected with two symmetrical contact air bags 3, and the other side of the contact air bag 3 is connected with a fastening ring 4.

[0034] In actual implementation, the contact force generated by the contact air bag 3 can act on the fastening ring 4, and the fastening ring 4 can generate a clamping force to ensure the stability of the injection pen during carrying.

[0035] Referring to Figure 4 The opposite sides of the two fastening rings 4 are connected with anti-skid pads, and the anti-skid pads are integrally formed with anti-skid particles.

[0036] In actual implementation, the anti-skid particles increase the friction between the fastening ring 4 and the injection pen, and improve the anti-skid effect.

[0037] Referring to Figure 4 The refrigeration end of the semiconductor refrigerating device 202 is connected with a heat conduction block 5, the other side of the heat conduction block 5 is connected with a heat conduction clamping ring 9, and the other side of the heat conduction clamping ring 9 is connected with the storage cylinder 201.

[0038] In actual implementation, since the refrigeration end of the semiconductor refrigerating device 202 can be relatively limited in area, the heat conduction block 5 can quickly spread the low temperature generated by the refrigeration end, increase the contact area with the heat conduction clamping ring 9, and make more heat be transferred from the storage cylinder 201 to the refrigeration end of the semiconductor refrigerating device 202. The heat conduction clamping ring 9 has a ring structure and is closely connected with the storage cylinder 201. The ring structure can surround the outside of the storage cylinder 201, increase the contact area with the storage cylinder 201, and ensure that the heat from all directions of the storage cylinder 201 can be effectively collected and conducted to the heat conduction block 5.

[0039] Referring to Figure 1The outer surface of the heat preservation cylinder 1 is provided with a plurality of ventilation holes 6, the plurality of ventilation holes 6 are distributed at equal intervals in a circumferential array with the axis of the heat preservation cylinder 1 as the center, and the inner diameter of the ventilation hole 6 gradually decreases along the air inlet path.

[0040] In specific implementation, the inner diameter of the ventilation hole 6 gradually decreases along the air inlet path, when the external air is sucked into the ventilation hole 6 by the heat dissipation fan 204, due to the gradually narrowing channel of the ventilation hole 6, according to the principle of fluid continuity, the flow rate of the air will gradually increase, and then the heat will be carried away faster, the plurality of ventilation holes 6 are distributed at equal intervals in a circumferential array with the axis of the heat preservation cylinder 1 as the center, this layout can make the air entering the heat preservation cylinder 1 uniformly distributed around the heat dissipation plate 203.

[0041] Referring to Figure 1 The heat preservation cylinder 1 is detachably connected with a hanging belt 8 by using a snap fastener, and the hanging belt 8 is integrally formed with a buffer pad.

[0042] In specific implementation, the setting of the hanging belt 8 makes it more convenient to carry the heat preservation cylinder 1, and the setting of the buffer pad improves the comfort of the user when carrying.

[0043] Referring to Figure 1 The heat preservation cylinder 1 is inserted with a cylinder cover, the cylinder cover is connected with a digital display thermometer 7, and the cylinder cover is connected with a thermometer, and the thermometer is electrically connected with the digital display thermometer 7.

[0044] In specific implementation, the setting of the digital display thermometer 7 makes it convenient for the user to keep track of the temperature change in the heat preservation cylinder 1, and the setting of the thermometer makes it convenient to detect the temperature in the cylinder.

[0045] Referring to Figure 1 One side of the heat preservation cylinder 1 is provided with a charging port, and the charging port corresponds to the semiconductor refrigeration piece 202.

[0046] In specific implementation, the setting of the charging port makes it convenient to use a power bank or other external power supply to supply power to the semiconductor refrigeration piece 202.

[0047] Working principle: when in normal use, the injection pen to be cooled can be placed in the storage cylinder 201 for storage, at the same time, when the temperature rises, the heat is transferred from the insulin injection pen and the surrounding air in the storage cylinder 201 to the refrigeration end of the semiconductor refrigeration device 202, thereby reducing the temperature in the storage cylinder 201, so as to achieve the cold storage of insulin. Since the plurality of storage cylinders 201 are distributed at equal intervals in the circumferential array in the heat preservation cylinder 1, the semiconductor refrigeration device 202 can simultaneously cool the plurality of storage cylinders 201, ensuring that the insulin at each position can be in a suitable low-temperature environment. The heat generated by the semiconductor refrigeration device 202 is conducted through the heat dissipation plate 203 which is in contact with the heat dissipation end. The heat dissipation fan 204 is connected to the side of the heat dissipation plate 203 away from the semiconductor refrigeration device 202. When the heat dissipation fan 204 starts, it will promote air flow, ensuring that the semiconductor refrigeration device 202 can work continuously and stably.

[0048] The inner diameter of the air vent 6 gradually decreases along the air inlet path. When the external air is sucked into the air vent 6 by the heat dissipation fan 204, due to the gradually narrowing channel of the air vent 6, according to the principle of fluid continuity, the flow rate of the air will gradually increase, thereby faster removing the heat. A plurality of air vents 6 are distributed at equal intervals in a circumferential array with the axis of the heat preservation cylinder 1 as the center. This layout can make the air entering the heat preservation cylinder 1 uniformly distributed around the heat dissipation plate 203.
