[0022] In order to make the technical problems, technical solutions and beneficial effects to be solved by this application more clearly understood, this application is further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain this application and are not intended to limit this application.

[0023] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as commonly understood by those skilled in the art to which this application belongs; the terms used herein are for the purpose of describing specific embodiments only and are not intended to limit this application. The terms "including" and "having" and any variations thereof in the specification and claims of this application and the accompanying drawings are intended to cover non-exclusive inclusions.

[0024] When users forcefully close the refrigerator door for a long time, if the magnetic sealing strip does not have a buffer component, it is easy for the magnetic sealing strip to be damaged or deformed, resulting in a loose seal, which affects the cooling effect and produces a loud noise when closing the refrigerator door.

[0025] Based on this, in order to improve the problem of poor buffering effect of the magnetic sealing strip itself in the related art.

[0026] See also Figure 1 and Figure 4 A magnetic door seal with an inflatable support bag includes an annular frame 1, a sealing component 2, a buffer component 3 and a connecting component 4. The sealing component 2, the buffer component 3 and the connecting component 4 are all arranged on the annular frame 1. The annular frame 1 is provided with a connecting groove 5. The sealing component 2 is used to seal the door, the buffer component 3 is used to buffer the door, and the connecting component 4 is used to connect the sealing component 2 and the annular frame 1.

[0027] Optionally, in some embodiments, see Figure 2 and Figure 4 The sealing component 2 includes an annular sealing protrusion 21, an annular sealing shell 22 and a magnetic strip 23. The annular sealing shell 22 is arranged on the annular frame 1, the annular sealing protrusion 21 is arranged on the annular sealing protrusion 21, and an annular filling cavity 6 is opened inside the annular sealing protrusion 21. The buffer component 3 is fixed inside the annular filling cavity 6, and the magnetic strip 23 is arranged inside the annular filling cavity 6. The sealing component 2 also includes a sealing outer baffle 24, which is fixed on both sides of the annular sealing shell 22. The sealing outer baffle 24 is located on the top surface of the annular frame 1. The buffer component 3 includes a sound-absorbing sponge 31 and an inflatable support bag 32. The inflatable support bag 32 is fixed to the bottom of the annular filling cavity 6. The magnetic strip 23 is fixed on the top surface of the inflatable support bag 32. The sound-absorbing sponge 31 is fixed on the top surface of the magnetic strip 23. The sum of the thicknesses of the magnetic strip 23, the sound-absorbing sponge 31 and the inflatable support bag 32 is the same as the depth of the annular filling cavity 6.

[0028] With such arrangement, when the user closes the refrigerator door, the inflatable support bag 32 is arranged at the bottom of the annular sealing shell 22. When the annular sealing shell 22 contacts the door frame, the sound-absorbing sponge 31 arranged inside the annular sealing shell 22 can have a good sound-absorbing effect, so that the sound of closing the door is small and the impact on the surrounding environment is reduced. Then the magnetic strip 23 located below the sound-absorbing sponge 31 is adsorbed on the door frame to fix the refrigerator door on the door frame. Then, the inflatable support bag 32 will cushion the force generated by the user when closing the refrigerator door, thereby increasing the cushioning effect when closing. The sealed outer baffles 24 arranged on both sides of the annular sealing shell 22 can improve the overall sealing, protect the sealing strip from collision and wear from external objects, thereby extending the service life of the sealing strip. It has certain elasticity and wear resistance, and effectively prevents dust or debris from entering the interior of the refrigerator.

[0029] Optionally, in some embodiments, see Figure 4 The connecting component 4 includes a buckle 41, a hook surface 42 and an adhesive layer 43. The buckle 41 is arranged on the bottom surface of the annular sealing shell 22, and the buckle 41 is buckled and connected to the connecting groove 5. The buckle 41 is provided with the hook surface 42, and the adhesive layer 43 is provided on the bottom surface of the annular sealing shell 22, and the adhesive layer 43 is located on both sides of the buckle 41.

[0030] With such a configuration, when the user uses the refrigerator door, he first inserts the buckle 41 provided at the bottom of the annular sealing shell 22 into the connecting groove 5 provided on the annular frame 1, so that the buckle 41 is connected to the connecting groove 5 by the buckle 41, so that the annular sealing shell 22 is fixed on the annular frame 1, and then the adhesive layer 43 provided on the bottom of the annular sealing shell 22 is bonded to the top of the annular frame 1, so that the connection between the annular sealing shell 22 and the annular frame 1 is more firmly, thereby improving the stability of the overall structure, ensuring that the annular sealing shell 22 is firmly installed on the refrigerator door, preventing it from loosening or detaching, reducing the wear and deformation of the annular sealing shell 22 during the door opening and closing process, and extending its service life.

[0031] Working principle: When the user uses the refrigerator door, first, the buckle 41 provided at the bottom of the annular sealing shell 22 is inserted into the connecting groove 5 provided on the annular frame 1, so that the buckle 41 is connected with the connecting groove 5 by the buckle 41, so that the annular sealing shell 22 is fixed on the annular frame 1, and then the adhesive layer 43 provided on the bottom of the annular sealing shell 22 is bonded with the top of the annular frame 1, so that the connection between the annular sealing shell 22 and the annular frame 1 is more firmly established, thereby improving the stability of the overall structure. When the user closes the refrigerator door, the inflatable support bag 32 is provided at the bottom of the annular sealing shell 22, and the annular sealing shell 22 is opened. When the sealing shell 22 contacts the door frame, the sound-absorbing sponge 31 arranged inside the annular sealing shell 22 can play a good sound-absorbing effect, making the sound of closing the door small and reducing the impact on the surrounding environment. Then the magnetic strip 23 located below the sound-absorbing sponge 31 is adsorbed on the door frame to fix the refrigerator door on the door frame. Then, the force generated by the user when closing the refrigerator door will be cushioned by the inflatable support bag 32 to a certain extent, thereby increasing the cushioning effect when closing. The sealed outer baffles 24 arranged on both sides of the annular sealing shell 22 can improve the overall sealing and protect the sealing strip from collision and wear from external objects.

[0032] The above description is merely a preferred embodiment of the present invention; however, the scope of protection of the present invention is not limited thereto. Any person skilled in the art who, within the technical scope disclosed in the present invention, makes equivalent substitutions or modifications based on the technical solutions and improved concepts of the present invention shall be covered by the scope of protection of the present invention.
