[0032] In order to further understand the purpose, structure, features, and functions of the present application, the embodiments are described in detail as follows.

[0033] In view of the above problem that the front cover 3 of the air duct is difficult to disassemble, the present application provides a refrigeration device, which comprises an inner container 1 and an air duct assembly 2 with a front cover 3, the edge of the front cover 3 is provided with at least one elastic lock catch 4 which is detachably connected with the inner container 1, the elastic lock catch 4 comprises a supporting seat 5 and a buckle piece 6, the supporting seat 5 comprises a first rear wall 51 and a first bottom wall 53 which are connected vertically, the first bottom wall 53 is provided with a limiting piece 55, when the buckle piece 6 is away from the first rear wall 51, the limiting piece 55 limits the buckle piece 6, and the buckle piece 6 is not detachable with the inner container 1; when the buckle piece 6 is pressed to be close to the first rear wall 51, the buckle piece 6 is detachable with the inner container 1.

[0034] The refrigeration device is mainly composed of an inner container 1 and an air duct assembly 2 with a front cover 3, the inner container 1 is surrounded to form a refrigeration compartment for containing and storing food or other articles that need to be refrigerated, and the air duct assembly 2 guides the circulation of cold air in the inner container 1 to achieve the refrigeration effect of the compartment of the refrigeration device.

[0035] The front cover 3 is provided with at least one elastic lock catch 4, which comprises a supporting seat 5 and a buckle piece 6. The supporting seat 5 provides support and fixation for the buckle piece 6. The first back wall 51 of the supporting seat 5 provides a support force for the buckle piece 6 from the back side to the front side, i.e., the first back wall 51 limits the maximum pressing displacement of the buckle piece 6 during pressing. When the buckle piece 6 is gradually pressed close to the first back wall 51, the buckle piece 6 gradually separates from the inner container 1. The supporting seat 5 further comprises a first bottom wall 53, which is connected perpendicularly to the first back wall 51 to form the bottom of the supporting seat 5. The surface of the first bottom wall 53 that is in contact with the buckle piece 6 is provided with a limiting piece 55 that cooperates with the buckle piece 6. After the front cover 3 and the inner container 1 are assembled, the limiting piece 55 limits the maximum distance of the buckle piece 6 from the first back wall 51, ensuring the close connection between the buckle piece 6 and the inner container 1.

[0036] The maximum pressing displacement is the maximum distance that the buckle piece 6 can move when it is pressed by an external force.

[0037] The back side is closer to the middle of the front cover 3 than the front side.

[0038] The number of lock catches is determined according to the size and shape of the front cover 3 to ensure the stability of the connection and the convenience of disassembly. Typically, the lock catches are evenly distributed around the edge of the front cover 3 to withstand uniform tension.

[0039] The limiting piece 55 is configured to gradually increase in thickness in the direction towards the first back wall 51, forming a wedge-shaped structure, i.e., the low end of the wedge is farther away from the first back wall 51, and the high end is closer to the first back wall 51.

[0040] During assembly, the buckle piece 6 starts from the relatively low end of the wedge and gradually moves to the relatively high end of the wedge along the wedge-shaped surface as the assembly continues. When the buckle piece 6 moves to the high end of the wedge and continues to move towards the first back wall 51, the high end of the limiting piece 55 effectively limits the buckle piece 6 from moving too far away from the first back wall 51 and falling out of the supporting seat 5.

[0041] After assembly is complete, the limiting piece 55 limits the buckle piece 6 to prevent it from continuing to move away from the first back wall 51 and falling out, ensuring the close connection between the front cover 3 and the inner container 1.

[0042] When the front cover 3 needs to be disassembled, pressing the buckle piece 6 close to the first back wall 51 allows the front cover 3 to be easily removed from the inner container 1.

[0043] The buckle piece 6 comprises a concave part 65 that is adapted to the limiting piece 55. After assembly, the limiting piece 55 is located in the concave part 65.

[0044] The shape and size of the concave part 65 match the wedge-shaped structure of the limiting part 55, ensuring that the two can achieve limiting.

[0045] During assembly, the concave part 65 of the buckle 6 is aligned with the limiting part 55, and with the action of pressing or pushing, the concave part 65 gradually contains the wedge-shaped part of the limiting part 55. When the assembly is completed, the limiting part 55 is completely located in the concave part 65 of the buckle 6, and the wedge-shaped structure of the limiting part 55 closely fits the concave part 65, forming an effective limiting effect, preventing the buckle 6 from continuing to move away from the first rear wall 51 and causing disengagement.

[0046] The elastic lock 4 provided by the application can achieve stable connection of the air duct front cover 3 and the inner container 1, and also makes the disassembly process more convenient.

[0047] The elastic lock 4 further comprises an elastic part 56, and the two ends of the elastic part 56 abut against the first rear wall 51 and the buckle 6, respectively.

[0048] Specifically, the elastic part 56 is arranged between the first rear wall 51 of the support seat 5 and the buckle 6, providing the buckle 6 with continuous elastic force, so that the buckle 6 can automatically move away from the first rear wall 51 when not subjected to external force, and is limited by the limiting part 55. At this time, the front cover 3 and the inner container 1 are tightly connected.

[0049] When the front cover 3 needs to be disassembled, the buckle 6 only needs to be pressed to make the buckle 6 move close to the first rear wall 51 against the elastic force of the elastic part 56, so that the front cover 3 can be easily disassembled from the inner container 1.

[0050] The buckle 6 further comprises a receiving cavity 66 in which the elastic part 56 is accommodated, and one end of the elastic part 56 away from the receiving cavity 66 abuts against the first rear wall 51.

[0051] The receiving cavity 66 is arranged on the vertical wall of the buckle 6 close to the first rear wall 51, and the shape and size of the receiving cavity 66 match those of the elastic part 56. The elastic part 56 is installed into the receiving cavity 66 of the buckle 6, ensuring that one end of the elastic part 56 abuts against the bottom of the receiving cavity 66, and the other end extends out of the receiving cavity 66 and abuts against the first rear wall 51 of the support seat 5.

[0052] The receiving cavity 66 provides the elastic part 56 with a correct installation direction and elastic force transmission guide. It ensures that the elastic part 56 can move along the predetermined path of the receiving cavity 66 when being pressed or released, improving the flexibility and response speed of the elastic lock 4 during installation and disassembly.

[0053] In an embodiment, the elastic part 56 is a spring, and the receiving cavity 66 is an inner cavity with a circular radial cross-section.

[0054] The support base 5 further comprises at least one side wall 52, which is provided with at least one sliding groove 54 extending towards the first back wall 51, and the buckle member 6 is provided with at least one sliding block 64 slidable in the sliding groove 54.

[0055] The side wall 52 is vertically arranged with the first bottom wall 53, and the side wall 52 is provided with at least one sliding groove 54 extending towards the first back wall 51, and the buckle member 6 is provided with at least one sliding block 64 matched with the sliding groove 54. The sliding groove 54 provides a sliding path for the sliding block 64 on the buckle member 6, so that the buckle member 6 can slide along the sliding groove 54 towards the first back wall 51 when subjected to force, thereby improving the flexibility and stability during the installation and disassembly of the elastic lock 4.

[0056] The sliding groove 54 is generally in the shape of a long strip, and the length and width of the sliding groove 54 are determined according to the sliding requirement of the buckle member 6 and the installation space. The sliding block 64 is generally in the shape of a long strip or a cylinder and is matched with the sliding groove 54. The size of the sliding block 64 should be slightly smaller than that of the sliding groove 54, so that the sliding block 64 can slide flexibly in the sliding groove 54. Specifically, the groove depth of the sliding groove 54 should be sufficient to accommodate the sliding block 64 and ensure that the sliding block 64 will not fall out during the sliding process.

[0057] In an optional embodiment, the side wall 52 comprises a first side wall 521 and a second side wall 522 opposite to each other, and the first side wall 521 and the second side wall 522 are both provided with at least one sliding groove 54.

[0058] The first side wall 521 and the second side wall 522 are oppositely arranged, and the opposite surfaces of the first side wall 521 and the second side wall 522 are both provided with at least one sliding groove 54 extending towards the first back wall 51. The two sides of the buckle member 6 are both provided with at least one sliding block 64 matched with the sliding groove 54 of the first side wall 521 and the second side wall 522. The sliding groove 54 provides a sliding path for the sliding block 64 on the buckle member 6, so that the buckle member 6 can slide along the sliding groove 54 towards the first back wall 51 when subjected to force, thereby improving the flexibility and stability during the installation and disassembly of the elastic lock 4.

[0059] The sliding groove 54 is generally in the shape of a long strip, and the length and width of the sliding groove 54 are determined according to the sliding requirement of the buckle member 6 and the installation space. The sliding block 64 is generally in the shape of a long strip or a cylinder and is matched with the sliding groove 54. The size of the sliding block 64 should be slightly smaller than that of the sliding groove 54, so that the sliding block 64 can slide flexibly in the sliding groove 54. Specifically, the groove depth of the sliding groove 54 should be sufficient to accommodate the sliding block 64 and ensure that the sliding block 64 will not fall out during the sliding process.

[0060] In another embodiment, the first side wall 521 and the second side wall 522 are arranged in parallel.

[0061] The cooperation of the sliding groove 54 and the sliding block 64 of the double side walls of the first side wall 521 and the second side wall 522 provides a more stable sliding path for the buckle 6, ensures that the buckle 6 can slide along the predetermined path between the two side walls when subjected to force, and improves the stability of the elastic lock 4.

[0062] The support seat 5 is integrally formed or separately formed with the front cover 3.

[0063] The integrally formed means that the support seat 5 and the front cover 3 are directly connected together by a one-time forming process such as injection molding or die casting during the manufacturing process to form an integral whole, and no additional installation steps are required during assembly, thereby simplifying the assembly process.

[0064] The separately formed means that the support seat 5 and the front cover 3 are formed separately during the manufacturing process and then connected together by a connection method such as buckling or screwing. The separately formed allows the support seat 5 and the front cover 3 to be designed, manufactured and replaced separately, thereby improving the flexibility of the product.

[0065] The buckle 6 includes a hook end 61 extending away from the first rear wall 51, and the inner container 1 includes a fixed port matched therewith. When the hook end 61 is buckled to the fixed port, the front cover 3 and the inner container 1 are not detachable. When the buckle is pressed to be close to the first rear wall 51, the hook end 61 releases the fixed port, and the front cover 3 and the inner container 1 are detachable.

[0066] The hook end 61 is arc-shaped or curved to better match the fixed port of the inner container 1. The fixed port is arc-shaped or groove-shaped to match the hook end 61 of the buckle 6.

[0067] When the hook end 61 is buckled to the fixed port, the front cover 3 and the inner container 1 are tightly connected. Specifically, during installation, the front cover 3 and the inner container 1 are aligned, the hook end 61 of the buckle 6 enters the fixed port of the inner container 1 and is fixedly connected. When the front cover 3 is disassembled, the buckle is pressed to be close to the first rear wall 51. At this time, during the pressing process, the elastic member 56 is compressed. With the compression of the elastic member 56, the hook end 61 of the buckle 6 is gradually released from the fixed port of the inner container 1. When the hook end 61 is completely released from the fixed port, the front cover 3 and the inner container 1 become detachable, and the front cover 3 can be easily removed from the inner container 1.

[0068] In an optional embodiment, the buckle 6 further includes a pressing end 62 arranged below the hook end 61. During the pressing process, external force is applied to the pressing end 62, the elastic member 56 is compressed, and with the compression of the elastic member 56, the hook end 61 of the buckle 6 is gradually released from the fixed port of the inner container 1. When the hook end 61 is completely released from the fixed port, the front cover 3 and the inner container 1 become detachable, and the front cover 3 can be easily removed from the inner container 1.

[0069] Two elastic buckles 4 are arranged on each of the opposite side edges of the front cover 3.

[0070] Two elastic buckles 4 are arranged on each of the opposite side edges of the front cover 3. Specifically, two elastic buckles 4 are arranged on each of the opposite side edges of the front cover 3, so that the connection between the front cover 3 and the inner container 1 is evenly stressed, avoiding damage caused by excessive stress at a single point. Through the action of multiple elastic buckles 4, the front cover 3 and the inner container 1 can be more effectively fixed, and the leakage of cold air in the air duct can also be prevented.

[0071] Of course, the position and number of elastic buckles 4 are not limited in the present application.

[0072] The present application provides a refrigeration device, which comprises an inner container 1 and an air duct assembly 2 having a front cover 3. The front cover 3 is provided with at least one elastic buckle 4 that is detachably connected to the inner container 1. The elastic buckle 4 comprises a support seat 5 and a buckle member 6. The support seat 5 comprises a first rear wall 51 and a first bottom wall 53 that are connected vertically. The first bottom wall 53 is provided with a limiting piece 55. When the buckle member 6 is away from the first rear wall 51, the limiting piece 55 limits the buckle member 6. The buckle member 6 is not detachable from the inner container 1. When the buckle member 6 is pressed to be close to the first rear wall 51, the buckle member 6 is detachable from the inner container 1. Through the buckle member 6 being away from or close to the first rear wall 51, the front cover 3 of the air duct and the inner container 1 are stably buckled or easily detached relative to the inner container 1, avoiding damage to the inner container 1 of the refrigeration device when the front cover 3 is detached.
