Specifically, the positioning means is a recess adapted to the anti-skid pad 852 on the bottom wall 918 of the breast milk refrigerator. In this way, when the breast milk refrigerator is mounted in the package 910, the anti-slip pad 852 is correspondingly mounted in the recess, and the position of the breast milk refrigerator with respect to the package 910 is fixed.
As an alternative, the bottom wall 918 of the breast milk refrigerator is fixed to the bottom of the package 910 by magnetic attraction. That is, two magnetically coupled magnetic members are respectively disposed at the bottom of the package 910 and the bottom of the breast milk refrigerator.
As an alternative, the bottom wall 918 of the breast milk refrigerator is fixed to the bottom wall 918 of the package 910 by a stopper. For example, the two sides of the bottom wall 918 of the package 910 are provided with the limit protrusions, which are in contact with the side wall of the milk refrigerator, so as to limit the milk refrigerator in the package 910, thereby achieving the positioning function.
Further, referring to fig. 1, when the package 910 is in the unfolded state, the side portion of the package 910 is in a semicircular channel shape. In this way, the hot air discharged from the breast milk refrigerator is advantageously discharged to the outside of the package 910 through the interval 916 between the side wall of the package 910 and the side wall of the breast milk refrigerator.

The technical effect of the breast milk refrigerating device is that the carrying carrier brings, and the beneficial effect is the same as that of the carrying carrier, and the repeated description is omitted.
Further, referring to fig. 2, a distance d between the side wall of the breast milk refrigerator and the side wall 913 of the package 910 is not less than 0.5cm. Specifically, d is 2cm to 3cm. Therefore, on one hand, the heat generated by the breast milk refrigerator can be well dissipated, and on the other hand, the structural compactness of the carrying carrier can be ensured.
In one embodiment, referring to fig. 3, 4-6 and 12, the breast milk refrigerator includes a liner 100, a housing 200, a semiconductor refrigerator 300, a cooling block 400 and a heat dissipation component. The liner 100 is provided with a chamber 111 for receiving a breast milk bag 500. The liner 100 is installed in the housing 200. The semiconductor refrigerator 300 includes a cold end surface and a hot end surface, the cold end surface contacts with the cold guide block 400, the cold guide block 400 contacts with the outer sidewall of the liner 100, and the heat dissipation component is disposed on the hot end surface.
When the breast milk refrigerator works, the heat is outwards diffused by the heat radiating component on the hot end surface of the semiconductor refrigerator 300, and the cold energy is continuously transmitted to the inner container 100 by the cold conducting block 400 on the cold end surface of the semiconductor refrigerator 300, so that the inner container 100 continuously transmits the cold energy to the breast milk bag 500 arranged in the cavity 111 for a long time. In addition, the semiconductor refrigerator 300, the cooling block 400 and the heat dissipation assembly are combined to the housing 200 to have a small overall size, a light weight, and portability.
Further, referring to fig. 5, the shape of the end surface of the cold guide block 400 contacting the cold end surface is adapted to the cold end surface. That is, the area of the end surface of the cold guide block 400 contacting the cold end surface is the same as the area of the cold end surface. The other end surface of the cold guide block 400 contacts the bottom of the liner 100. Thus, thermal short-circuiting between the cold guide block 400 and the heat sink can be avoided.
In one embodiment, referring to fig. 5 and 6, one side wall of the cold guide block 400 is provided with a first concave portion 410, and the other side wall of the cold guide block 400 is provided with a second concave portion 420. Specifically, the first recess 410 and the second recess 420 are semi-cylindrical. The first concave portion 410 and the second concave portion 420 are provided with a size according to the actual situation, and the cooling capacity is not affected by the cooling block 400, so that the weight of the cooling block 400 can be reduced to a certain extent, and the weight of the breast milk refrigerator can be reduced.

The wing portions 440 increase the end surface area of the cold guide block 400 facing the inner container 100 to a certain extent, so that the contact area between the cold guide block 400 and the outer sidewall of the bottom of the inner container 100 can be increased, and the heat resistance of cold conduction is reduced, thereby being beneficial to the cold guide block 400 to conduct the cold to the inner container 100. In addition, the cooling capacity is uniformly conducted to the bottom of the liner 100, and the cooling performance of the liner 100 is enhanced. In addition, the wing 440 can facilitate the connection 130 to connect and assemble the cold guide block 400 and the liner 100 to each other.

In this way, the pressure generated in the foaming process of the foaming insulation layer 710 is applied to the wing portions 440 of the cold guide block 400, so that the joint between the cold guide block 400 and the bottom of the liner 100 is tighter, and the heat resistance of cold conduction is reduced; in addition, the foaming insulation layer 710 enables the cold guide block 400 and the liner 100 to be combined into a whole, so that the structure is firmer and more reliable. Specifically, the housing 200 includes a detachable partition 210, and the mounting opening 211 is provided on the partition 210.
In one embodiment, referring to fig. 4 and 8, the heat dissipating component includes a heat sink 610 and a heat dissipating fan 620. The heat sink 610 contacts the hot end surface for removing heat from the hot end surface. The heat dissipation fan 620 is used to dissipate heat from the heat sink 610. That is, the heat dissipation fan 620 blows wind to flow through the heat sink 610 to take away heat on the heat sink 610, thereby performing a heat dissipation function. The air outlet surface of the cooling fan 620 may directly face the radiator 610, or may be diagonally opposite to the radiator 610, or the air outlet surface of the cooling fan 620 may be led into the radiator 610 by the air deflector 630.
Further, referring to fig. 3 and 4, the heat sink 610 includes a heat dissipation plate 611 and a plurality of fin plates 612 disposed on the heat dissipation plate 611 at intervals. The heat dissipation plate 611 is used to contact with the hot end surface. Specifically, the fin plate 612 is an aluminum fin or a copper fin, or the like. In this way, the heat is guided to the heat dissipation plate 611 by the heat end surface of the semiconductor refrigerator 300, and the heat is redirected to the fin plate 612 by the heat dissipation plate 611, thereby achieving a good heat dissipation effect.
Further, referring to fig. 3,4, 8 and 9, a side of the fin plate 612 facing away from the heat dissipation plate 611 is a bevel edge 6121 inclined with respect to a plate surface of the heat dissipation plate 611, and the bevel edge 6121 contacts with an air outlet surface of the heat dissipation fan 620. In this way, on one hand, the air outlet surface of the cooling fan 620 is closer to the radiator 610, so that heat on the radiator 610 can be better taken away; on the other hand, the air outlet surface of the cooling fan 620 contacts the inclined edge 6121 of the fin plate 612, so that the effective thickness D f cos a of the cooling fan 620 can be reduced as much as possible, and the total height of the cooling assembly can be greatly reduced to D 2, which is beneficial to reducing the volume of the device and facilitating storage, transportation and carrying.
Further, referring to fig. 3, 4, 8 and 9, the breast milk refrigerator further includes a bracket 810, a power supply 820 and a control board 830.

The heat sink 610, the heat dissipation fan 620, the power supply 820, and the control board 830 are all mounted on the bracket 810. The power supply 820 is specifically a rechargeable battery or a storage battery, and the power supply 820 is provided to the control board 830, and the control board 830 controls the cooling fan 620 and the semiconductor refrigerator 300 to operate.
Referring to fig. 4, 8 and 9, the total height of the heat dissipating assembly is D 2, the thickness of the heat sink 610 is D s, and the thickness and frame length of the heat dissipating fan 620 are D f and L f, respectively. Further, the air outlet surface of the cooling fan 620 is inclined with respect to the hot end surface, and the inclination angle of the cooling fan 620 is set to a, and accordingly, D 2＝Dfcos a+Ds. Thus, as a becomes larger from smaller, the thickness D s of the heat sink 610 becomes smaller, which is advantageous for the design of decreasing the thickness D s of the heat sink 610, and the heat dissipation wind resistance of the heat dissipation fan 620 is decreased, and the noise is decreased. However, as the angle a increases, the heat dissipation area of the heat dissipation fan 620 also gradually decreases, and the fan elevation angle thickness L f sin a (see FIG. 9) increases, and when L fsina>Ds is increased, the thickness D s of the heat sink 610 and the effective thickness D f cos a of the heat dissipation fan 620 will be larger than the conventional structure values, so the maximum value of a isIn this embodiment, the value range of a is specifically 5 ° to 45 ° in consideration of the above three factors.
Taking a 9025 type cooling fan 620 (thickness D f is 25mm, side length L f is 90 mm) as an example, when a=45° the corresponding height D 2 of the cooling component is close to 63mm, when the design thickness D s of the radiator 610 is reduced, a needs to be further reduced, and the optimum value of a is finally found by combining the thickness D s, wind resistance, cooling area, etc. of the radiator 610. When the height D 2 of the heat dissipation component is smaller, the whole size of the breast milk refrigerator can be correspondingly smaller. In addition, since the cooling fan 620 is laterally blown by the inclination angle a, on the basis of reducing the overall height, the dead angle of the airflow caused by directly blowing the semiconductor radiator 610 is avoided (when the air is directly blown, the projection of the motor part of the cooling fan 620 on the radiator 610 is generally located at the position of the semiconductor radiator 610, which is just the dead angle of the airflow of the cooling fan 620), so that the cooling efficiency is improved.
In this embodiment, the power supply 820 and the control board 830 are both located on the same side of the cooling fan 620, or the power supply 820 and the control board 830 are located on different sides of the cooling fan 620.
