Description

Technical Field

[0001] This utility model relates to the field of coffee machines, and in particular to a brewing device and a coffee machine. Background Technology

[0002] Coffee machine brewing mechanisms typically involve extracting coffee, which usually occurs at high pressure, making the brewing mechanism prone to deformation or even breakage. However, traditional coffee machine brewing mechanisms lack reinforcement structures or have insufficient reinforcement to prevent deformation or breakage, severely impacting the product's lifespan. Therefore, improvements are needed to address this shortcoming. Utility Model Content

[0003] Therefore, it is necessary to address the problem that traditional coffee brewing devices lack reinforcement structures or whose reinforcement structures are insufficient to prevent deformation or even breakage, which severely affects the product's lifespan. This paper proposes a brewing device and a coffee machine.

[0004] A brewing device includes: a support assembly having a receiving space; a brewing assembly disposed on the support assembly and movable relative to the support assembly, the brewing assembly being movable at least to a working position relative to the support assembly; a reinforcing shell disposed on the support assembly and extending along the height direction of the support assembly, the reinforcing shell being located at the receiving space; and a reinforcing block disposed on the brewing assembly, the reinforcing block being located outside the brewing assembly, the reinforcing block abutting against the reinforcing shell when the brewing assembly is in the working position.

[0005] The first aspect of this application discloses a brewing device in which the brewing component can move relative to the supporting component. When the brewing component moves to the working position, the reinforcing block on the brewing component abuts against the reinforcing shell on the supporting component. This adds a high-pressure resistance structure to the original structure, dispersing the high pressure during extraction and greatly enhancing the overall rigidity and deformation resistance of the brewing device under high-pressure conditions. This design effectively prevents the brewing device from bursting at the point where the reinforcing block and the reinforcing shell abut against each other due to high pressure during operation. It directly strengthens and protects the weakest areas of the brewing device most susceptible to damage from high pressure, fundamentally avoiding fatigue cracking or bursting problems caused by stress concentration in the weak areas of the brewing device, and significantly improving the durability and reliability of the product. Moreover, it ensures that the brewing component remains stable in the working position during high-pressure extraction, effectively suppressing pressure leakage or operational instability that may be caused by component deformation or displacement, ensuring the stability of coffee extraction quality, and eliminating potential safety hazards by preventing structural failure.

[0006] In one embodiment, the support assembly has a first spatial wall and a second spatial wall disposed opposite to each other, forming the receiving space between the first spatial wall and the second spatial wall. There are two reinforcing shells, both disposed on the support assembly. One of the two reinforcing shells is located at the first spatial wall, and the other is located at the second spatial wall. The number of reinforcing blocks is the same as the number of reinforcing shells, and when the brewing assembly is in the working position, the reinforcing blocks and reinforcing shells abut against each other in a one-to-one correspondence. This one-to-one abutment between the two reinforcing shells and the two reinforcing blocks allows the high extraction pressure to be simultaneously transmitted to the stress points on both sides of the support assembly. This design avoids the potential for eccentric loading or torsional torque caused by unilateral force, ensuring that the pressure is evenly distributed along both sides of the support assembly, thereby greatly improving structural stability and overall rigidity, and enhancing the product's resistance to deformation.

[0007] In one embodiment, the support assembly has a second spatial wall and a third spatial wall arranged adjacent to each other, and the adjacent sides of the reinforcing shell are connected to the second spatial wall and the third spatial wall, respectively. In one design, the third spatial wall is located at the top of the receiving space, and the first and second spatial walls are located on the sides of the receiving space. By connecting the adjacent sides of the reinforcing shell to the second and third spatial walls, the reinforcing shell has extremely strong bending and torsional rigidity, so that the reinforcing shell can withstand high pressure environments after abutting against the reinforcing block, and will not cause product deformation or even breakage due to high pressure.

[0008] In one embodiment, a reinforcing rib is further included, which is disposed on the support assembly. The adjacent sides of the reinforcing rib are connected to the third spatial wall and the reinforcing shell, respectively. By connecting the adjacent sides of the reinforcing rib to the third spatial wall and the reinforcing shell, an additional rigid connection is added, enhancing the connection strength between the reinforcing shell and the third spatial wall of the support assembly, thereby improving the deformation resistance of the reinforcing shell. This design further ensures that the product will not crack under high pressure.

[0009] In one embodiment, the support component has a first spatial wall and a second spatial wall disposed opposite to each other, with the receiving space formed between the first spatial wall and the second spatial wall. A first limiting portion and a second limiting portion are respectively formed opposite to each other on the first spatial wall and the second spatial wall. The first limiting portion is connected to the reinforcing shell or is disposed adjacent to the reinforcing shell. A guide groove is formed between the support component, the first limiting portion, and the second limiting portion. A portion of the brewing component is located at the guide groove, and the brewing component can move within the guide groove. The connection between the first limiting portion and the reinforcing shell enhances the structural strength of the reinforcing shell and improves its resistance to deformation. Preferably, the brewing component, with a portion located at the guide groove, cooperates with the guide groove, increasing the overall structural compactness, improving the overall structural strength, and ensuring the product's resistance to deformation. Furthermore, it provides a precise linear motion trajectory for the movement of the brewing component, allowing it to move accurately to the working position.

[0010] In one embodiment, the brewing assembly includes a slide, a brewing shell, and a movable cylinder assembly. The slide is disposed on the support assembly and located at the guide groove. The brewing shell is disposed on the slide, and the reinforcing block is disposed on the brewing shell and located outside the brewing shell. The movable cylinder assembly is movably disposed on the brewing shell. By positioning the slide at the guide groove and engaging with the guide groove, precise movement can be achieved while ensuring the product's resistance to deformation. The movable placement of the movable cylinder assembly on the brewing shell allows for adjustment of the brewing cavity depth formed by the movable cylinder assembly and the brewing shell.

[0011] In one embodiment, a limiting space is formed between the reinforcing block and the slide, and the reinforcing shell is located in the limiting space when the brewing assembly is in the working position. Preferably, by having the reinforcing shell abut against the space wall of the limiting space when the brewing assembly is in the working position, the deformation resistance of the reinforcing shell can be improved.

[0012] In one embodiment, when the brewing component is in the working position, the reinforcing shell and the first limiting part are located in the limiting space, with the reinforcing shell abutting against the reinforcing block and the first limiting part abutting against the slide. By having the reinforcing shell abut against the reinforcing block and the first limiting part abut against the slide, the stability and load-bearing capacity of the overall structure are greatly enhanced, and the strength of this part to resist complex stresses and deformations is significantly improved.

[0013] In one embodiment, the system further includes a housing and a powder scraper assembly. The housing is disposed on the slide and located in the limiting space. The housing abuts against both the slide and the reinforcing housing. The powder scraper assembly is disposed on the housing and located inside the housing. By having the housing abut against both the slide and the reinforcing housing, the structure is strengthened and its resistance to deformation is improved. Simultaneously, the powder scraper assembly is stably installed, enabling it to scrape coffee grounds off the brewing housing.

[0014] In one embodiment, the reinforcing shell is integrated with the support assembly, and the reinforcing block is integrated with the brewing assembly. By integrating the reinforcing shell with the support assembly and the reinforcing block with the brewing assembly, the connection rigidity and integrity between the reinforcing shell and the support assembly, as well as between the reinforcing block and the brewing assembly, are enhanced, giving the product extremely high resistance to deformation and tearing when subjected to high pressure.

[0015] A coffee machine includes: the brewing device described above.

[0016] The second aspect of this application discloses a coffee machine that, through the design of its brewing device, achieves extremely high structural reliability and stability in the core high-pressure extraction process. This design enables the coffee machine's brewing device to effectively withstand long-term, high-frequency high-pressure impacts, fundamentally overcoming problems such as shell deformation or cracking that easily occur in the brewing devices of traditional coffee machines under these conditions.

[0038] To better understand the above-mentioned objectives, features, and advantages of this utility model, the present utility model will be further described in detail below with reference to the accompanying drawings and specific embodiments. It should be noted that, unless otherwise specified, the embodiments and features described in these embodiments can be combined with each other.

[0039] Many specific details are set forth in the following description in order to provide a full understanding of the present invention. However, the present invention may also be implemented in other ways different from those described herein. Therefore, the scope of protection of the present invention is not limited to the specific embodiments disclosed below.

[0040] Example 1

[0041] like Figure 1-13As shown, this embodiment discloses a brewing device, including: a support assembly 1, the support assembly 1 having a receiving space 101; a brewing assembly 2, the brewing assembly 2 being disposed on the support assembly 1, the brewing assembly 2 being movable relative to the support assembly 1, the brewing assembly 2 being at least movable relative to the support assembly 1 to a working position; a reinforcing shell 3, the reinforcing shell 3 being disposed on the support assembly 1, the reinforcing shell 3 extending along the height direction of the support assembly 1, the reinforcing shell 3 being located at the receiving space 101; and a reinforcing block 4, the reinforcing block 4 being disposed on the brewing assembly 2, the reinforcing block 4 being located outside the brewing assembly 2, the reinforcing block 4 abutting against the reinforcing shell 3 when the brewing assembly 2 is in the working position.

[0042] The first aspect of this application discloses a brewing device in which the brewing component 2 can move relative to the supporting component 1. When the brewing component 2 moves to the working position, the reinforcing block 4 on the brewing component 2 abuts against the reinforcing shell 3 on the supporting component 1. This adds a high-pressure resistance structure to the original structure, disperses the high pressure during extraction, and greatly enhances the overall rigidity and deformation resistance of the brewing device under high-pressure conditions. This design effectively prevents the brewing device from bursting at the point where the reinforcing block 4 abuts against the reinforcing shell 3 due to high pressure during operation. It directly strengthens and protects the weakest areas of the brewing device most susceptible to damage from high pressure, fundamentally avoiding fatigue cracking or bursting problems caused by stress concentration in the weak areas of the brewing device, and significantly improving the durability and reliability of the product. Moreover, it ensures that the brewing component 2 remains stable in the working position during high-pressure extraction, effectively suppressing pressure leakage or operational instability that may be caused by component deformation or displacement, ensuring the stability of coffee extraction quality, and eliminating potential safety hazards by preventing structural failure.

[0043] like Figure 5-7As shown, in addition to the features of the above embodiments, this embodiment further specifies that: the support component 1 has a first spatial wall 1011 and a second spatial wall 1012 disposed opposite to each other, and the receiving space 101 is formed between the first spatial wall 1011 and the second spatial wall 1012; the number of reinforcing shells 3 is two, both of which are disposed on the support component 1; one of the two reinforcing shells 3 is located at the first spatial wall 1011, and the other of the two reinforcing shells 3 is located at the second spatial wall 1012; the number of reinforcing blocks 4 is the same as the number of reinforcing shells 3, and when the brewing component 2 is in the working position, the reinforcing blocks 4 and the reinforcing shells 3 abut against each other in a one-to-one correspondence. Specifically, the first spatial wall 1011 is on one side of the receiving space 101, and the second spatial wall 1012 is on the opposite side of the receiving space. By having the two reinforcing shells 3 and the two reinforcing blocks 4 abut against each other in a one-to-one correspondence, the extraction high pressure can be simultaneously transmitted to the force points on both sides of the support component 1. This design avoids the off-center load or torque that may be generated by unilateral force, and ensures that the pressure is evenly distributed along both sides of the support component 1, thereby greatly improving the structural stability and overall rigidity, and enhancing the product's resistance to deformation.

[0044] like Figure 9-12 As shown, in addition to the features of the above embodiments, this embodiment further specifies that: the support component 1 has a second spatial wall 1012 and a third spatial wall 1013 arranged adjacently, and the adjacent sides of the reinforcing shell 3 are respectively connected to the second spatial wall 1012 and the third spatial wall 1013. In one design, the third spatial wall 1013 is located at the top of the receiving space 101, and the first spatial wall 1011 and the second spatial wall 1012 are located on the sides of the receiving space 101. By connecting the adjacent sides of the reinforcing shell 3 to the second spatial wall 1012 and the third spatial wall 1013 respectively, the reinforcing shell 3 has extremely strong bending and torsional rigidity, so that the reinforcing shell 3 can resist the high pressure environment after abutting against the reinforcing block 4, and will not cause the product to deform or even break due to high pressure. Specifically, the top of the receiving space is the third spatial wall 1013, so the third spatial wall 1013 is adjacent to the first spatial wall 1011 and the second spatial wall 1012.

[0045] like Figure 9-12As shown, in addition to the features of the above embodiments, this embodiment further includes a reinforcing rib 5, which is disposed on the support assembly 1. The adjacent sides of the reinforcing rib 5 are respectively connected to the third spatial wall 1013 and the reinforcing shell 3. By connecting the adjacent sides of the reinforcing rib 5 to the third spatial wall 1013 and the reinforcing shell 3, an additional rigid connection is added, enhancing the connection strength between the reinforcing shell 3 and the third spatial wall 1013 of the support assembly 1, thereby improving the deformation resistance of the reinforcing shell 3. This design further ensures that the product will not crack under high pressure.

[0046] like Figure 5-7 As shown, in addition to the features of the above embodiments, this embodiment further specifies that: the support component 1 has a first spatial wall 1011 and a second spatial wall 1012 disposed opposite to each other, and the receiving space 101 is formed between the first spatial wall 1011 and the second spatial wall 1012; a first limiting part 11 disposed opposite to each other is formed on the first spatial wall 1011 and the second spatial wall 1012; a second limiting part 12 disposed opposite to each other is formed on the first spatial wall 1011 and the second spatial wall 1012; the first limiting part 11 is connected to the reinforcing shell 3 or is disposed adjacent to the reinforcing shell 3; a guide groove 102 is formed between the support component 1, the first limiting part 11 and the second limiting part 12; a portion of the brewing component 2 is located at the guide groove 102; and the brewing component 2 is movable at the guide groove 102. The connection between the first limiting part 11 and the reinforcing shell 3 enhances the structural strength of the reinforcing shell 3 and improves its resistance to deformation. The brewing component 2 is located at the guide groove 102. Preferably, the brewing component 2 cooperates with the guide groove 102, which can increase the compactness of the overall structure, improve the overall structural strength, and ensure the product's resistance to deformation. Moreover, it provides a precise linear motion trajectory for the movement of the brewing component 2, enabling the brewing component 2 to move accurately to the working position.

[0047] like Figure 13As shown, in addition to the features of the above embodiments, this embodiment further specifies that: the brewing assembly 2 includes a slide 21, a brewing shell 22, and a moving cylinder assembly 23. The slide 21 is disposed on the support assembly 1 and located at the guide groove 102. The brewing shell 22 is disposed on the slide 21. The reinforcing block 4 is disposed on the brewing shell 22 and located on the outside of the brewing shell 22. The moving cylinder assembly 23 is movably disposed on the brewing shell 22. By having the slide 21 located at the guide groove 102 and cooperating with the guide groove 102, precise movement can be achieved while ensuring the product's resistance to deformation. By having the moving cylinder assembly 23 movably disposed on the brewing shell 22, the depth of the brewing cavity formed by the moving cylinder assembly 23 and the brewing shell 22 can be adjusted.

[0048] like Figure 5-7 and Figure 13 As shown, in addition to the features of the above embodiments, this embodiment further specifies that: a limiting space 201 is formed between the reinforcing block 4 and the slide 21, and the reinforcing shell 3 is located in the limiting space 201 when the brewing component 2 is in the working position. Preferably, by having the reinforcing shell 3 located in the limiting space 201 when the brewing component 2 is in the working position, the reinforcing shell 3 abuts against the space wall of the limiting space 201, thereby improving the deformation resistance of the reinforcing shell 3.

[0049] like Figure 5-7 and Figure 13 As shown, in addition to the features of the above embodiments, this embodiment further specifies that: when the brewing component 2 is in the working position, the reinforcing shell 3 and the first limiting part 11 are located in the limiting space 201, the reinforcing shell 3 abuts against the reinforcing block 4 and the first limiting part 11 abuts against the slide 21. By having the reinforcing shell 3 abut against the reinforcing block 4 and the first limiting part 11 abut against the slide 21, the stability and load-bearing capacity of the overall structure are greatly enhanced, and the strength of this part to resist complex stress and deformation is significantly improved.

[0050] like Figure 5 and Figure 6 As shown, in addition to the features of the above embodiments, this embodiment further includes a housing 6 and a powder scraper assembly 7. The housing 6 is disposed on the slide 21 and located at the limiting space 201. The housing 6 abuts against both the slide 21 and the reinforcing housing 3. The powder scraper assembly 7 is disposed on the housing 6 and located inside the housing 6. By abutting against both the slide 21 and the reinforcing housing 3, the structure is strengthened and its resistance to deformation is improved. Simultaneously, the powder scraper assembly 7 is stably installed, enabling it to scrape coffee powder off the brewing housing 22. Preferably, the housing 6 and the slide 21 are integrally formed.
