[0024] In order to make the technical problems, technical solutions and beneficial effects to be solved by the present application more clearly understood, the present application is further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present application and are not used to limit the present application.

[0027] In addition, the terms "first" and "second" are used for descriptive purposes only and should not be understood as indicating or implying relative importance or implicitly indicating the number of the indicated technical features. Thus, a feature defined as "first" or "second" may explicitly or implicitly include one or more of the features. In the description of this application, the meaning of "plurality" is two or more, unless otherwise clearly and specifically defined.

[0028] The sealing ring of the existing coffee machine is difficult to adapt to capsule pocket components of different sizes and specifications, and it is difficult to seal coffee capsules of different sizes and specifications.

[0029] Based on the above reasons, the embodiment of the present application provides a sealing ring, which is annular, and includes a fixed ring, an inner sealing ring and an outer sealing ring. The inner sealing ring, the outer sealing ring and the bottom of the fixed ring are connected, the inner sealing ring extends obliquely downward from the fixed ring to form a contracted structure, and the outer sealing ring extends obliquely downward from the fixed ring to form an expanded structure. When in use, the sealing ring in the embodiment of the present application can be sealed by the inner sealing ring and the capsule pocket assembly with a smaller diameter, and can be sealed by the outer sealing ring and the capsule pocket assembly with a larger diameter, and can also be sealed by the inner sealing ring, the outer sealing ring and the capsule pocket assembly at the same time, and can adapt to capsule pocket assemblies of different sizes, thereby improving the adaptability of the coffee machine.

[0030] In some scenarios, a sealing ring according to an embodiment of the present application can be applied to a capsule coffee machine, so that the capsule coffee machine can be adapted to capsule pocket assemblies of different sizes and specifications, thereby improving the adaptability of the coffee machine to different coffee capsules.

[0031] A sealing ring provided in an embodiment of the present application is described in detail below with reference to specific examples.

[0032] Figure 1 A schematic diagram of the cross-sectional structure of a sealing ring provided in an embodiment of the present application is shown in FIG. Figure 1 As shown in 1, the sealing ring 1 is annular, and the sealing ring 1 includes a fixed ring 11, an inner sealing ring 12 and an outer sealing ring 13. The inner sealing ring 12, the outer sealing ring 13 and the bottom of the fixed ring 11 are connected. The inner sealing ring 12 extends obliquely downward from the fixed ring 11 to form a contracting structure, and the outer sealing ring 13 extends obliquely downward from the fixed ring 11 to form a flaring structure.

[0033] like Figure 1 As shown, the sealing ring 1 includes a fixed ring 11, an inner sealing ring 12 and an outer sealing ring 13. The fixed ring 11 is the main supporting structure of the sealing ring 1, and the inner sealing ring 12 and the outer sealing ring 13 play a role in sealing with the capsule pocket assembly at the bottom of the fixed ring 11.

[0034] like Figure 1As shown, the inner sealing ring 12 extends obliquely downward from the fixing ring 11 to form a constricted structure, so that the inner sealing ring 12 can cooperate with the capsule pocket assembly with a smaller opening to seal.

[0035] like Figure 1 As shown, the outer sealing ring 13 extends obliquely downward from the fixing ring 11 to form an expanded structure, so that the outer sealing ring 13 can cooperate with the capsule pocket assembly with a larger mouth to seal.

[0036] When the width of the mouth of the capsule pocket assembly is relatively large, the mouth of the capsule pocket assembly can be sealed by the inner sealing ring 12 and the outer sealing ring 13 at the same time.

[0037] The beneficial effect brought about by the above-mentioned implementation method is that the inner sealing ring, the outer sealing ring and the mouth of the capsule pocket assembly cooperate with each other to seal, thereby improving the size range of the sealing ring and the capsule pocket assembly, improving the adaptability of the coffee machine to the size of the capsule pocket assembly and the coffee capsule, and improving the user experience of the coffee machine.

[0038] In some implementations, a recessed portion 14 is formed between the inner sealing ring 12 and the outer sealing ring 13 .

[0039] like Figure 1 As shown, when the inner sealing ring 12 and the outer sealing ring 13 are deformed, the recessed portion 14 can form a yielding structure between the inner sealing ring 12 and the outer sealing ring 13, thereby ensuring the sealing effect when the inner sealing ring 12 and the outer sealing ring 13 are deformed.

[0040] The beneficial effect brought about by the above implementation method is that the sealing effect can be guaranteed when the inner sealing ring and the outer sealing ring are deformed.

[0041] In some implementations, the sealing ring 1 is made of soft material.

[0042] The sealing ring 1 is made of soft material, so that the sealing ring 1 can be fully deformed when squeezed, and can cooperate with the capsule pocket assembly to seal.

[0043] Exemplarily, the sealing ring 1 may be made of soft silicone.

[0044] The beneficial effect brought about by the above implementation manner is that the sealing ring can be fully deformed when squeezed and cooperate with the capsule pocket assembly to perform sealing.

[0045] In some implementations, the cross-sections of the inner sealing ring 12 and the outer sealing ring 13 are both straight, and the inclination angles of the inner sealing ring 12 and the outer sealing ring 13 are 30 degrees to 80 degrees.

[0046] like Figure 1As shown, the cross sections of the inner sealing ring 12 and the outer sealing ring 13 are both straight lines, so that the inner sealing ring 12 and the outer sealing ring 13 can be in close contact with the mouth of the capsule pocket assembly after deformation.

[0047] like Figure 1 As shown, the inclination angle of the inner sealing ring 12 is α1, and the inclination angle of the outer sealing ring 13 is α2. The inclination angles α1 and α2 of the inner sealing ring 12 and the outer sealing ring 13 are 30 to 80 degrees, so that the inner sealing ring 12 and the outer sealing ring 13 can be tilted to fit the mouth of the capsule pocket assembly when squeezed.

[0048] For example, the inclination angle of the inner sealing ring 12 is α1, and the inclination angle of the outer sealing ring 13 is α2, which may be 45°, 60° or 70°.

[0049] The beneficial effect brought about by the above implementation method is that the inner sealing ring and the outer sealing ring can be tilted when squeezed and the mouth of the capsule pocket assembly can remain in a fitted state.

[0050] In some implementations, a horizontally disposed inner guide surface 121 is disposed on the bottom surface of the end of the inner sealing ring 12 .

[0051] like Figure 1 As shown, the bottom surface of the end of the inner sealing ring 12 is provided with a horizontal inner guide surface 121 , and the horizontal inner guide surface 121 can slide relative to the mouth of the capsule pocket assembly to facilitate positioning of the end of the inner sealing ring 12 .

[0052] The beneficial effect brought about by the above implementation is that the horizontally arranged guide surface facilitates the positioning of the end of the inner sealing ring.

[0053] In some implementations, a horizontally disposed outer guide surface 131 is disposed on a bottom surface of the end of the outer sealing ring 13 .

[0054] like Figure 1 As shown, the bottom surface of the end of the outer sealing ring 13 is provided with a horizontal outer guide surface 131 , and the horizontal outer guide surface 131 can slide relative to the mouth of the capsule pocket assembly to facilitate positioning of the end of the outer sealing ring 13 .

[0055] The beneficial effect brought about by the above implementation is that the horizontally arranged outer guide surface facilitates the positioning of the end of the outer sealing ring.

[0056] In some implementations, a horizontally extending outer extension portion 132 is provided on the circumference of the distal end of the outer sealing ring 13 .

[0057] like Figure 1As shown, the outer extension portion 132 can increase the diameter of the outer sealing ring 13 in the horizontal direction, thereby increasing the diameter range of the outer sealing ring 13 that can cooperate with the seal and improving the sealing effect of the outer sealing ring 13 on the capsule pocket assembly.

[0058] The beneficial effect brought about by the above implementation method is that the sealing effect of the outer sealing ring on the capsule pocket assembly is improved.

[0059] In some implementations, a top sealing ring 15 is connected to the top of the inner wall of the fixing ring 11 , and the top sealing ring 15 extends laterally toward the inner side of the fixing ring 11 and then extends downward.

[0060] like Figure 1 As shown, a top sealing ring 15 is connected to the top of the inner side wall of the fixing ring 11, and the top sealing ring 15 is used to cooperate with the brewing head assembly to seal and prevent the coffee liquid from leaking from the circumference of the brewing head assembly.

[0061] like Figure 1 As shown, the top sealing ring 15 extends laterally toward the inner side of the fixing ring 11 and then extends downward, so that the top sealing ring 15 can fit the outer side wall of the brewing head assembly after extending laterally. The downward extension of the top sealing ring 15 can ensure the circumferential sealing effect of the brewing head assembly.

[0062] The beneficial effect brought about by the above implementation is that it can prevent the coffee liquid from leaking in the circumferential direction of the brewing head assembly.

[0063] In some implementations, the bottom height of the top sealing ring 15 is higher than the top height of the inner sealing ring 12 .

[0064] like Figure 1 As shown, the bottom height of the top sealing ring 15 is higher than the top height of the inner sealing ring 12, so that the inner sealing ring 12 will not interfere with the bottom of the top sealing ring 15 after bending and deformation, thereby ensuring the sealing effect of the inner sealing ring 12 on the capsule pocket assembly.

[0065] The beneficial effect brought about by the above implementation method is that the sealing effect of the inner sealing ring on the capsule pocket assembly is guaranteed.

[0066] An embodiment of the present application also provides a coffee machine, which includes the sealing ring 1 of any of the above items, and also includes a capsule pocket assembly 2 and a brewing head assembly 3. The sealing ring 1 is connected to the brewing head assembly 3, and the sealing ring 1 is used to cooperate with the capsule pocket assembly 2 for sealing.

[0067] Figure 2 This is a schematic cross-sectional structure diagram of a first coffee machine provided in an embodiment of the present application. Figure 3 for Figure 2 A schematic diagram of the local structure of a coffee machine at A, Figure 4 This is a partial structural schematic diagram of another capsule pocket assembly of the second coffee machine provided in an embodiment of the present application. Figure 5 A partial structural diagram of another capsule pocket assembly of the third coffee machine provided in an embodiment of the present application is shown in FIG. Figures 2 to 5 As shown, the sealing ring 1 can cooperate with the capsule pocket assembly 2 and can ensure the sealing performance between the sealing ring 1 and the capsule pocket assembly 2.

[0068] In some implementations, when the outer diameter of the mouth of the capsule pocket assembly 2 is smaller than the diameter of the fixing ring 11 , the mouth of the capsule pocket assembly 2 and the inner sealing ring 12 fit tightly and seal.

[0069] like Figure 3 As shown, when the outer ring diameter of the mouth of the capsule pocket assembly 2 is smaller than the diameter of the fixing ring 11 , the mouth of the capsule pocket assembly 2 and the inner sealing ring 12 fit and seal, so that the inner sealing ring 12 can seal the mouth of the capsule pocket assembly 2 .

[0070] In some implementations, when the inner diameter of the mouth of the capsule pocket assembly 2 is larger than the diameter of the fixing ring 11 , the mouth of the capsule pocket assembly 2 and the outer sealing ring 13 fit tightly and seal.

[0071] like Figure 4 As shown, when the inner diameter of the mouth of the capsule pocket assembly 2 is larger than the diameter of the fixing ring 11 , the mouth of the capsule pocket assembly 2 and the outer sealing ring 13 fit and seal, so that the outer sealing ring 13 can seal the mouth of the capsule pocket assembly 2 .

[0072] In some implementations, when the inner diameter of the mouth of the capsule pocket assembly 2 is smaller than the diameter of the fixing ring 11 and the outer diameter of the mouth of the capsule pocket assembly 2 is larger than the diameter of the fixing ring 11, the mouth of the capsule pocket assembly 2 is sealed against the inner sealing ring 12 and the outer sealing ring 13 at the same time.

[0073] like Figure 5 As shown, when the inner diameter of the mouth of the capsule pocket assembly 2 is smaller than the diameter of the fixing ring 11, and the outer diameter of the mouth of the capsule pocket assembly 2 is larger than the diameter of the fixing ring 11, the mouth of the capsule pocket assembly 2 is simultaneously sealed with the inner sealing ring 12 and the outer sealing ring 13, which can further ensure the sealing effect of the mouth of the capsule pocket assembly 2.

[0074] The beneficial effect brought about by the above implementation method is that the coffee machine uses the above sealing ring to seal capsule pocket assemblies of different sizes and specifications, thereby ensuring the sealing of capsule pocket assemblies of different sizes and specifications and improving the adaptability of the coffee machine to different coffee capsules.

Any modifications, equivalent substitutions and improvements made within the spirit and principles of the present application should be included in the protection scope of the present application.
