[0002] As a household appliance, a refrigerator can store food and prevent food from spoiling in a refrigerated manner. A nitrogen generation device for a refrigerator is installed in the refrigerator. The air pump in the nitrogen generation device for a refrigerator is the main excitation source of the nitrogen preservation module. When the air pump works, it will cause great vibration of the nitrogen generation device for a refrigerator, thereby affecting its subsequent use. Currently, in the prior art, an air pump box provided with an air pump is generally installed on the base of the nitrogen generation device for a refrigerator to fix the air pump on the nitrogen generation device for a refrigerator.

[0003] The mechanism of installing the above air pump on the nitrogen generation device for a refrigerator through the air pump box will directly transmit the vibration generated when the air pump works to the nitrogen generation device for a refrigerator, which will damage the structure of the nitrogen generation device for a refrigerator to a certain extent and affect the use of the refrigerator. Summary of the Utility Model

[0004] The technical problem to be solved by the utility model is to overcome the defect that the use of the nitrogen generation device for a refrigerator is affected due to the vibration of the air pump in the prior art, and to provide a nitrogen generation device for a refrigerator and a refrigerator including the same.

[0005] The utility model solves the above technical problem through the following technical solutions:

[0006] A nitrogen generation device for a refrigerator, the nitrogen generation device for a refrigerator includes an air pump box and a base, and the nitrogen generation device for a refrigerator further includes a buffer member made of an elastic material;

[0007] The air pump box and the base are detachably connected;

[0008] The buffer member is arranged between the connection surfaces of the air pump box and the base.

[0009] In this solution, the air pump box and the base are detachably connected, so that the air pump box can be removed from the base to check its condition; the buffer member is arranged between the connection surfaces of the air pump box and the base. The above arrangement makes the vibration generated on the air pump box not directly transmitted to the base. The arrangement of the buffer member will reduce the vibration transmitted from the air pump box to the base and prevent large vibration from causing structural and functional damage to the nitrogen generation device for a refrigerator.

[0010] Preferably, the air pump box and the base can be connected through a detachable member. One of the air pump box and the base is provided with a detachable member, and the other is connected with a buffer member. The buffer member is connected with the detachable member.

[0011] In this solution, the provision of the detachable part facilitates the easier removal of the air pump box from the base. Secondly, the setting of a detachable part between the air pump box and the base also helps to consume (i.e., reduce) the vibration generated during the transmission of the vibration from the air pump box to the base; in addition, both the buffer part and the detachable part can be connected to the air pump box or the base, which enhances the flexibility and general applicability of the above structure.

[0012] Preferably, the detachable part includes a body, a mounting part, and a clamping part, and the mounting part and the clamping part are disposed on opposite sides of the body;

[0013] Among them, the body is connected to the base through the mounting part, and the body is detachably connected to the buffer part through the clamping part.

[0014] In this solution, the setting of the mounting part and the clamping part makes the detachable connection between the air pump box and the base more firm and compact. Secondly, the mounting part and the clamping part are disposed on opposite sides of the body, so that the connection between the air pump box and the base and the body will not interfere with each other.

[0015] Preferably, the detachable part further includes a first positioning part, and the first positioning part is disposed on the side of the body facing the base;

[0016] A second positioning part is provided on the base, and the second positioning part is adapted to the first positioning part to limit the movement of the body relative to the base.

[0017] In this solution, the setting of the first positioning part is conducive to finding the precise installation position of the air pump box and the base. The adaptation of the second positioning part to the first positioning part helps to prevent the detachable part from loosening, and thus prevent the air pump box from loosening.

[0018] Preferably, the mounting part has a first groove, and a plurality of connecting pieces are arranged at intervals in the first groove. The connecting pieces extend from the bottom of the first groove in a direction away from the clamping part and extend out of the first groove;

[0019] The body is connected to the base through a plurality of connecting pieces.

[0020] In this solution, the setting of the first groove can increase the contact area between the base and the detachable part, that is, the installation area, so that the detachable part is not easily loosened; in addition, the provision of a plurality of connecting pieces can make the detachable part more firmly connected to the base. In addition, the connecting pieces extend from the bottom of the first groove in a direction away from the clamping part and extend out of the first groove. The above setting method can increase the depth of the connection, further making the detachable part firmly connected to the base.

[0021] Preferably, the connecting piece is provided with a connection hole, and the connecting piece is detachably connected to the base through a threaded connecting piece passing through the connection hole;

[0022] And / or, a reinforcing plate is further disposed in the first groove, the bottom of the reinforcing plate is connected to the bottom of the first groove, and both ends of the reinforcing plate are respectively connected between the outer wall surface of the connecting member and the inner wall surface of the first groove.

[0023] In this solution, the connecting member is detachably connected to the base through a threaded connecting member passing through the connecting hole, making the connection more stable; the setting method of the reinforcing plate can increase the strength of the detachable member.

[0024] Preferably, the engaging portion has a second groove for accommodating the buffer member and engagingly connecting with the buffer member;

[0025] And / or, the buffer member includes a first buffer member and a second buffer member. The first buffer member and the second buffer member are respectively fixed on the air pump box through detachable members and are respectively disposed on the left and right sides of the air pump box.

[0026] In this solution, the setting of the second groove can increase the contact area between the buffer member and the detachable member, that is, the installation area, making it not easy for the above two to loosen; in addition, the first buffer member and the second buffer member are disposed on the left and right sides of the air pump box, making the overall force of the air pump box balanced, preventing external forces from concentrating on a local part of the air pump box, resulting in easy loosening of other positions of the air pump box.

[0027] Preferably, an air pump is disposed inside the air pump box, a connecting pipe is provided on the air pump, a first end of the connecting pipe is connected to the air pump, and a second end of the connecting pipe passes through the first buffer member and the detachable member engaged with the first buffer member.

[0028] In this solution, the connecting pipe is used to discharge the gas generated by the air pump; the second end of the connecting pipe passes through the first buffer member and the detachable member engaged with the first buffer member. The above setting makes the connecting pipe not contact the air pump box and the base, and thus will not transmit vibration to the air pump box and the base, thereby preventing damage to the nitrogen generation device of the refrigerator.

[0029] Preferably, the first buffer member is provided with a through hole for the connecting pipe to pass through. On the side of the first buffer member facing away from the detachable member, a fixing portion is provided along the circumferential edge of the through hole in the direction of the connecting pipe passing through. The fixing portion extends from the surface of the first buffer member in a direction away from the detachable member;

[0030] The fixing portion is in the shape of a hollow frustum of a cone, and along the extending direction of the fixing portion, the diameter of the fixing portion decreases;

[0031] Wherein, one end of the fixing portion away from the surface of the first buffer member abuts against the outer wall surface of the connecting pipe.

[0032] In this solution, the setting of the fixing portion makes the connecting pipe not shake, and thus remains relatively stationary with the first buffer member, minimizing the damage to the nitrogen generation device of the refrigerator caused by the shaking of the connecting pipe.

[0033] The present utility model also provides a refrigerator, which includes the refrigerator nitrogen generation device as described above.

[0034] The positive and progressive effects of the present utility model are as follows: The air pump box and the base are detachably connected, so that the air pump box can be removed from the base to check its condition; the buffer is arranged between the connection surface of the air pump box and the base.

[0060] The following is a preferred embodiment, and the accompanying drawings are used to more clearly and completely illustrate the present invention, but the present invention is not limited to the scope of this embodiment.

[0061] As Figures 1 to 5 shown, the present invention provides a nitrogen generation device 1 for a refrigerator. The nitrogen generation device 1 for a refrigerator includes an air pump box 11 and a base 12. The nitrogen generation device 1 for a refrigerator further includes a buffer member made of an elastic material. The air pump box 11 and the base 12 are detachably connected. The buffer member is disposed between the connection surfaces of the air pump box 11 and the base 12.

[0062] In this embodiment, the air pump box 11 and the base 12 are detachably connected, so that the air pump box 11 can be removed from the base 12 to check its condition. The buffer member is disposed between the connection surfaces of the air pump box 11 and the base 12. The above arrangement enables the vibration generated on the air pump box 11 not to be directly transmitted to the base 12. The arrangement of the buffer member reduces the vibration transmitted from the air pump box 11 to the base 12, preventing large vibrations from causing structural and functional damage to the nitrogen generation device 1 for a refrigerator.

[0063] It should be noted that the buffer member can be installed at multiple positions between the connection surfaces of the air pump box 11 and the base 12 to enhance the connection effect.

[0064] Refer to Figure 1 and Figure 2 It can be understood that the air pump box 11 and the base 12 can be connected through a detachable member 14. One of the air pump box 11 and the base 12 is provided with the detachable member 14, and the other is connected with the buffer member. The buffer member is connected to the detachable member 14.

[0065] In this embodiment, the provision of the detachable member 14 facilitates the easier detachment of the air pump box 11 from the base 12. Secondly, the arrangement of a detachable member 14 between the air pump box 11 and the base 12 also helps to dissipate (i.e., reduce) the vibration generated when the vibration on the air pump box 11 is transmitted to the base 12. In addition, both the buffer member and the detachable member 14 can be connected to the air pump box 11 or the base 12, which enhances the flexibility and general applicability of the above structure.

[0066] It should be noted that for the above solution, it is only necessary to ensure that the buffer member and the detachable member 14 are located between the air pump box 11 and the base 12. The detachable member 14 can be arranged between the buffer member and the air pump box 11 or between the buffer member and the base 12.

[0067] Reference Figure 4 and Figure 5 It is to be understood that the detachable member 14 includes a body 141, a mounting portion 142, and a engaging portion 143. The mounting portion 142 and the engaging portion 143 are disposed on opposite sides of the body 141. Among them, the body 141 is connected to the base 12 through the mounting portion 142, and the body 141 is engaged and connected to the buffer member through the engaging portion 143.

[0068] In this embodiment, the arrangement of the mounting portion 142 and the engaging portion 143 makes the detachable connection between the air pump box 11 and the base 12 more firm and compact. Secondly, the mounting portion 142 and the engaging portion 143 are disposed on opposite sides of the body 141, so that the connections between the air pump box 11 and the base 12 and the body 141 will not interfere with each other.

[0069] It should be noted that in this embodiment, the structures of the mounting portion 142 and the engaging portion 143 are merely a preferred structural arrangement. However, in other alternative embodiments, the mounting portion 142 and the engaging portion 143 can also be arranged in any structure applicable thereto.

[0070] Reference Figure 1 and Figure 4 It is to be understood that the detachable member 14 further includes a first positioning portion 144. The first positioning portion 144 is disposed on the side of the body 141 facing the base 12. A second positioning portion 121 is provided on the base 12, and the second positioning portion 121 is adapted to the first positioning portion 144 to limit the movement of the body 141 relative to the base 12.

[0071] In this embodiment, the provision of the first positioning portion 144 helps to find the precise installation position of the air pump box 11 and the base 12. The adaptation of the second positioning portion 121 to the first positioning portion 144 helps to prevent the detachable member 14 from loosening, and thus prevent the air pump box 11 from loosening.

[0072] It should be noted that multiple first positioning portions 144 can be provided on the detachable member 14, and multiple second positioning portions 121 can also be provided on the base 12 to match them.

[0073] Refer to Figure 4 and Figure 5 For understanding, the installation portion 142 has a first groove 1421, and a plurality of connecting members 1422 are arranged at intervals in the first groove 1421. The connecting members 1422 extend from the bottom of the first groove 1421 in a direction away from the engaging portion 143 and extend out of the first groove 1421; the main body 141 is connected to the base 12 through the plurality of connecting members 1422.

[0074] In this embodiment, the setting of the first groove 1421 can increase the contact area between the base 12 and the detachable member 14, that is, the installation area, so that the detachable member 14 is not easily loosened; in addition, the setting of a plurality of connecting members 1422 can make the detachable member 14 more firmly connected to the base 12. In addition, the connecting members 1422 extend from the bottom of the first groove 1421 in a direction away from the engaging portion 143 and extend out of the first groove 1421. The above setting method can increase the connection depth, and further make the detachable member 14 firmly connected to the base 12.

[0075] It should be noted that the plurality of connecting members 1422 can be separated by partitions, and the partitions can also improve the strength of the detachable member 14.

[0076] Refer to Figure 1 and Figure 4 For understanding, the connecting member 1422 is provided with a connection hole 1423, and the connecting member 1422 is detachably connected to the base 12 through a threaded connecting member 1422 passing through the connection hole 1423; and / or, a reinforcing plate 1424 is further provided in the first groove 1421. The bottom of the reinforcing plate 1424 is connected to the bottom of the first groove 1421, and both ends of the reinforcing plate 1424 are respectively connected between the outer wall surface of the connecting member 1422 and the inner wall surface of the first groove 1421.

[0077] In this embodiment, the connecting member 1422 is detachably connected to the base 12 through a threaded connecting member 1422 passing through the connection hole 1423, making the connection more stable; the setting method of the reinforcing plate 1424 can increase the strength of the detachable member 14.

[0078] It should be noted that in addition to the connection hole 1423, other forms of connection methods can also be provided on the connecting member 1422, such as hinge connection or snap connection.

[0079] Refer to Figure 1 and Figure 4It is understood that the engaging portion 143 has a second groove 1431 for accommodating a buffer member and engagingly connecting with the buffer member; and / or, the buffer member includes a first buffer member 131 and a second buffer member 132, and the first buffer member 131 and the second buffer member 132 are respectively fixed to the air pump box 11 by detachable members 14 and are respectively disposed on the left and right sides of the air pump box 11.

[0080] In this embodiment, the provision of the second groove 1431 can increase the contact area, i.e., the installation area, between the buffer member and the detachable member 14, making it difficult for the two to become loose; in addition, the first buffer member 131 and the second buffer member 132 are disposed on the left and right sides of the air pump box 11, making the overall force on the air pump box 11 balanced and preventing external forces from concentrating on a local part of the air pump box 11, resulting in the loosening of other positions of the air pump box 11.

[0081] It should be noted that the second groove 1431 is set to a width such that the buffer member can just fit in, and it should not be too large or too small.

[0082] Reference Figure 1 and Figure 2 It is understood that an air pump 111 is provided inside the air pump box 11, and a connecting pipe 112 is provided on the air pump 111. The first end of the connecting pipe 112 is connected to the air pump 111, and the second end of the connecting pipe 112 passes through the first buffer member 131 and the detachable member 14 engaged with the first buffer member 131.

[0083] In this embodiment, the connecting pipe 112 is used to discharge the gas generated by the air pump 111; the second end of the connecting pipe 112 passes through the first buffer member 131 and the detachable member 14 engaged with the first buffer member 131. The above arrangement makes the connecting pipe 112 not contact the air pump box 11 and the base 12, and thus will not transmit vibration to the air pump box 11 and the base 12, thereby preventing damage to the refrigerator nitrogen generation device 1.

[0084] It should be noted that there are buffer members above and below the air pump 111, and there is a gap between the air pump 111 and the air pump box 11. The connecting pipe 112 sequentially passes through the buffer member above the air pump 111 and the first buffer member 131.

[0085] Reference Figure 1 and Figure 2It is understood that a through hole is provided on the first buffer member 131 for the connecting pipe 112 to pass through. On the side of the first buffer member 131 facing away from the detachable member 14, a fixing portion 113 is provided along the circumferential edge of the through hole in the direction of the connecting pipe 112 passing through. The fixing portion 113 extends from the surface of the first buffer member 131 in a direction away from the detachable member 14; the fixing portion 113 is in the shape of a hollow frustum of a cone, and along the extending direction of the fixing portion 113, the diameter of the fixing portion 113 decreases; wherein, one end of the fixing portion 113 away from the surface of the first buffer member 131 abuts against the outer wall surface of the connecting pipe 112.

[0086] In this embodiment, the setting of the fixing portion 113 prevents the connecting pipe 112 from jittering, and thus keeps it in a relatively static state with the first buffer member 131, minimizing the damage to the refrigerator nitrogen generation device 1 caused by the jitter of the connecting pipe 112.

[0087] It should be noted that a through hole is also provided on the detachable member 14 that cooperates with the first buffer member 131. The above through hole is also for the connecting pipe 112 to pass through, and it can also reduce the jitter of the connecting pipe 112; in addition, the fixing portion 113 is in close fit with the outer wall surface of the communicating pipe.

[0088] The present utility model also provides a refrigerator, which includes the refrigerator nitrogen generation device 1 as described above.

[0089] In this embodiment, the air pump box 11 and the base 12 are detachably connected, so that the air pump box 11 can be removed from the base 12 to check its condition; the buffer member is arranged between the connecting surfaces of the air pump box 11 and the base 12. The above arrangement makes the vibration generated on the air pump box 11 not directly transmitted to the base 12. The arrangement of the buffer member reduces the vibration transmitted from the air pump box 11 to the base 12, preventing large vibrations from causing structural and functional damage to the refrigerator nitrogen generation device 1.
