[0037] In the embodiment, the seal 10 is provided with a first inner cavity 114, and the first side 11 and the second side 12 are located on both sides of the first inner cavity 114. In the embodiment, the first inner cavity 114 makes the seal 10 softer and has stronger elastic deformation capability, which can improve the sealing performance of the storage space 910 when the cabinet door 800 is closed. In the embodiment, the seal 10 has a tubular structure, and the extension direction of the first inner cavity 114 is substantially the same as the extension direction of the seal 10, so that the elastic deformation capability of each part of the seal 10 is substantially the same, and the deformation degree of each part of the seal 10 is substantially the same when the cabinet door 800 is closed, so that the sealing performance of the storage space 910 is good. In other embodiments, the first inner cavity 114 can be a separate closed space, which is approximately in the form of a bubble. The seal 10 is provided with a plurality of bubble-shaped first inner cavities 114 in the extension direction thereof, and adjacent two inner cavities can be spaced apart or connected, so that the seal 10 has a certain hardness to avoid excessive closing of the cabinet door 800.
[0038] In the embodiment, the door seal 100 further comprises a connecting portion 20, which is arranged on the first side 11 and connected to the seal 10, and protrudes relative to the seal 10. In the embodiment, the connecting portion 20 is used to connect the cabinet door 800 or the cabinet body 900. As an example, the connecting portion 20 is arranged on the first side 11 of the seal 10, and the cabinet door 800 is provided with a fitting groove (not shown in the figure), and the connecting portion 20 is fitted into the fitting groove to connect the seal 10 to the cabinet door 800. In the embodiment, the connecting portion 20 is integrally formed with the seal 10, and the connecting portion 20 and the seal 10 are both structures capable of elastic deformation. In the embodiment, the structure at the opening of the fitting groove is a hard structure, and the size between the opposite sides of the opening of the fitting groove is smaller than the maximum size of the connecting portion 20, and the connecting portion 20 can be deformed to be fitted into the fitting groove through the opening of the fitting groove. When the connecting portion 20 is fitted into the fitting groove, the structure of the connecting portion 20 is fully or partially restored, so that the connection between the connecting portion 20 and the fitting groove is relatively stable. In the embodiment, the connecting portion 20 extends along the extension direction of the tubular seal 10, so that the parts of the seal 10 and the cabinet door 800 are tightly connected, and the sealing between the seal 10 and the cabinet door 800 is ensured.
[0039] In the embodiment, the door seal 100 further comprises a heat insulation filling body 30, which is arranged in the first inner cavity 114. In the embodiment, the heat insulation filling body 30 is a low thermal conductivity structure, and the material of the heat insulation filling body 30 can include aerogel, asbestos. In the embodiment, the heat insulation filling body 30 can include aerogel particles, and the particle size range of the aerogel particles is greater than or equal to 4 mm and less than or equal to 6 mm, for example, it can be 4 mm, 4.5 mm, 5 mm, 5.5 mm, 6 mm, etc. In other embodiments, the heat insulation filling body 30 can also include asbestos particles and the like. The heat insulation filling body 30 can hinder the cold quantity inside the refrigerator 2000 from being conducted to the external environment through the door seal 100, and can also hinder the external cold quantity from being transmitted to the incubator or the incubator through the door seal 100, so as to maintain the temperature in the storage space 910 within a preset temperature range, and avoid the loss of cold quantity or heat quantity.
[0040] In summary, the door seal 100 provided in the embodiment includes the seal 10, the connecting portion 20 and the heat insulation filling body 30.

In actual application scenarios, in the case that the cabinet door 800 and the cabinet body 900 clamp the sealing strip 10, the body structure of the second inner cavity 124 moves towards the first inner cavity 114, and when the body structure of the second inner cavity 124 contacts the support portion 113, the support portion 113 can abut against the body structure of the second inner cavity 124 to hinder the second inner cavity 124 and the magnetic member 40 from continuing to move towards the first inner cavity 114. With the arrangement in the embodiment, the support portion 113 improves the strength of the body structure of the first inner cavity 114, and can prevent the body structure of the first inner cavity 114 from being severely deformed under the extrusion of the magnetic member 40. In the embodiment, the door sealing strip 100 has a reference surface (not shown in the figure), and the structure of the door sealing strip 100 is approximately mirror-symmetrically arranged about the reference surface. The two support portions 113 are structures protruding from the inner surface of the first inner cavity 114, and the two support portions 113 are mirror-symmetrically arranged about the reference surface, so that the first inner cavity 114 is approximately mirror-symmetric about the reference surface when deformed.
[0045] In the embodiment, the sealing strip 10 is further provided with a third inner cavity 115 located at the first side 11. The third inner cavity 115 is arranged separately from the first inner cavity 114. The spatial volume of the first inner cavity 114 is small, and therefore the body structure of the third inner cavity 115 also has a certain strength. In the embodiment, the body structure of the third inner cavity 115 is substantially embedded in the body structure of the first inner cavity 114. The structure of the first inner cavity 114 is in a state of wrapping around part of the outer periphery of the third inner cavity 115. The body structure of the third inner cavity 115 extends towards the second inner cavity 124. In actual application scenarios, when the cabinet door 800 and the cabinet body 900 are clamped with the sealing strip 10, the body structure of the second inner cavity 124 moves towards the first inner cavity 114. When the body structure of the second inner cavity 124 contacts the body structure of the third inner cavity 115, the body structure of the third inner cavity 115 can abut against the body structure of the second inner cavity 124 to hinder the second inner cavity 124 and the magnetic piece 40 from continuing to move towards the first inner cavity 114, thereby avoiding the body structure of the first inner cavity 114 from being severely deformed under the extrusion of the magnetic piece 40. In the embodiment, the aforementioned connecting portion 1121 is part of the body structure of the first inner cavity 114, and the connecting portion 1121 is also part of the body structure of the third inner cavity 115. Therefore, the supporting portion 113 is connected to the body structure of the third inner cavity 115 to jointly abut against the body structure of the second inner cavity 124 and the magnetic piece 40. In the embodiment, the third inner cavity 115 is filled with air, i.e., the third inner cavity 115 is empty. In other embodiments, the third inner cavity 115 can be provided with a heat-insulating filling body 30.
[0046] In the embodiment, the connecting portion 20 and the third inner cavity 115 are arranged in sequence and side by side in the direction in which the second side 12 points to the first side 11. The connecting portion 20 is connected to the body structure of the third inner cavity 115, and the connecting portion 20 protrudes relative to the body structure of the third inner cavity 115. In the embodiment, the third inner cavity 115 is located between the connecting portion 20 and the first inner cavity 114. In the embodiment, the third inner cavity 115 is in a state of being embedded in the first inner cavity 114. In other embodiments, the form of the third inner cavity 115 and the form of the first inner cavity 114 can be arbitrarily arranged, and the forms of the two inner cavities do not need to match each other. In the embodiment, the third inner cavity 115 is filled with air, and the connecting portion 20 is arranged side by side with the third inner cavity 115. The connecting portion 20 can improve the stability of the form of the third inner cavity 115 and avoid the third inner cavity 115 from being severely deformed.

The second partition wall 112 in the present embodiment is recessed towards the inside of the first inner cavity 114, so that the space of the third inner cavity 115 is in a form of being wrapped by the first inner cavity 114. In the present embodiment, the pressure of the gas in the third inner cavity 115 on the second partition wall 112 is greater than the pressure of the heat insulation filling body 30 in the first inner cavity 114 on the second partition wall 112, so that the body structure of the third inner cavity 115 supports the body structure of the second inner cavity 124 and the magnetic member 40. With the arrangement in the present embodiment, the third inner cavity 115 is matched with the first inner cavity 114 in a concave-convex manner, so that the structure of the sealing strip 10 as a whole is simple and beautiful, and the outer surface of the sealing strip 10 is smooth and fluent.
