Description

TECHNICAL FIELD

[0001] The utility model relates to coffee machine field, in particular to a kind of bean bin structure and coffee machine. BACKGROUND

[0002] Bean bin structure is the component of coffee machine to store coffee beans, if the traditional coffee machine needs to observe the remaining amount of coffee beans inside bean bin structure, the cover of bean bin structure needs to be opened. Therefore, the remaining amount of coffee beans inside the bean bin structure of the traditional coffee machine cannot be observed intuitively and quickly, and the user may affect the coffee making process due to failure to replenish coffee beans in time, reducing the use efficiency. SUMMARY

[0003] Therefore, it is necessary to provide a bean bin structure and a coffee machine to solve the problem that the bean bin structure of the traditional coffee machine cannot be observed intuitively and quickly, and the user may affect the coffee making process due to failure to replenish coffee beans in time, reducing the use efficiency.

[0004] A bean bin structure includes a housing assembly provided with a mounting cavity, a bean bin assembly arranged on the housing assembly and located at the mounting cavity, part of the bean bin assembly being located outside the housing assembly, the bean bin assembly being provided with a coffee bean storage cavity, the part of the bean bin assembly located outside the housing assembly being provided with an opening, the opening being in communication with the coffee bean storage cavity, and a cover assembly arranged on the bean bin assembly and located at the opening.

[0005] The first aspect of the present application discloses a bean bin structure, by part of the bean bin assembly located outside the housing or part of the cover assembly being made of transparent material, a window for directly observing the coffee bean storage cavity is created, so that the user can see the inventory and state of the coffee beans in the cavity at any time. This design makes it easy to replenish coffee beans, and once the remaining amount of coffee beans is sufficient, the user does not need to perform the tedious and possibly futile process of opening, checking and closing, simplifying the user operation steps and making the daily use of the coffee machine more convenient and user-friendly. Moreover, fewer opening and closing times help to more stably maintain the suitable storage environment inside the coffee bean storage cavity, maximally reducing the contact of coffee beans with external humid air, thereby more effectively maintaining the freshness, flavor and quality of coffee beans. By part of the bean bin assembly being located outside the housing assembly, the observation area can be further increased, and the effect of intuitively observing the remaining amount of coffee beans can be improved.

[0006] In one of the embodiments, the bean bin assembly is made of transparent material. By making the bean bin assembly as a whole of transparent material, the material of the bean bin assembly is uniform, which facilitates the processing and manufacturing, reduces the processing complexity, and thus effectively improves the production efficiency and product consistency.

[0007] In one of the embodiments, the cover assembly is made of transparent material. By making the cover assembly of transparent material, the user can directly observe the remaining amount of coffee beans inside the bean storage cavity through the transparent cover assembly without opening the cover, which realizes instant viewing without operation. This not only greatly improves the convenience of use, but also maximizes the reduction of the contact between coffee beans and air, thereby better maintaining the freshness of coffee beans.

[0008] In one of the embodiments, the bean bin assembly is provided with an assembly space, the assembly space is in communication with the bean storage cavity, and the bean bin structure further includes an adjusting assembly, the adjusting assembly is arranged on the bean bin assembly and located at the assembly space, and the adjusting assembly is configured to be in transmission connection with the bean grinding device for adjusting the particle size of coffee powder ground by the bean grinding device. By locating the adjusting assembly at the assembly space, the adjusting assembly can work stably. By transmission connection between the adjusting assembly and the bean grinding device, the particle size of coffee powder ground by the bean grinding device can be controlled by operating the adjusting assembly, so as to ensure that the particle size of coffee powder meets the use requirements of the user.

[0009] In one of the embodiments, the bean grinding device includes a grinding outer knife assembly and a grinding inner knife assembly, the bean grinding device is provided with a powder outlet, a grinding gap is formed between the grinding outer knife assembly and the grinding inner knife assembly, the grinding gap is in communication with the powder outlet, the grinding outer knife assembly includes an outer knife structure and a lifting adjusting structure, the lifting adjusting structure is in transmission connection with the adjusting assembly, the lifting adjusting structure can rotate under the control of the adjusting assembly, the outer knife structure is movably arranged on the lifting adjusting structure, and the lifting adjusting structure can drive the outer knife structure to move towards or away from the grinding inner knife assembly when the lifting adjusting structure rotates. By transmission connection between the adjusting assembly and the lifting adjusting structure of the bean grinding device, the user can control the rotation of the lifting adjusting structure by the adjusting assembly, and the outer knife structure moves towards or away from the grinding inner knife assembly, so as to adjust the grinding gap between the grinding outer knife assembly and the grinding inner knife assembly. By adjusting the size of the grinding gap, the grinding fineness of coffee beans can be accurately controlled, which meets the requirements of different coffee making processes.

[0010] In one embodiment, the bean hopper assembly includes a bean hopper body and a mating structure. The bean hopper body is disposed on the housing assembly and located at the mounting cavity. The bean hopper body has a bean storage cavity and an opening. The mating structure is disposed on the bean hopper body and located within the bean storage cavity. The mating structure has an assembly space. The adjusting component is movably disposed on the mating structure and located at the assembly space. By movably disposing the adjusting component on the mating structure and located at the assembly space, the degrees of freedom of the adjusting component can be effectively restricted, allowing the adjusting component to only perform movements such as rotation. This enables the adjusting component to precisely control the rotation of the lifting and adjusting structure.

[0011] In one embodiment, the adjusting component is rotatable relative to the mating structure. The adjusting component can rotate at least a first angle and a second angle relative to the mating structure. When the adjusting component rotates to the first angle, the coffee powder particle size ground by the grinding device is greater than when the adjusting component rotates to the second angle. By allowing the adjusting component to rotate relative to the mating structure, and by allowing different rotation angles to correspond to different coffee powder particle sizes, a precise and predictable grinding adjustment function is achieved. Specifically, when the adjusting component rotates to the first angle, the grinding gap increases; when the adjusting component rotates to the second angle, the grinding gap decreases, effectively adjusting the coffee powder particle size.

[0012] In one embodiment, a first limiting portion is formed on the adjusting component, and a first limiting surface and a second limiting surface are formed on opposite sides of the first limiting portion. A second limiting portion is formed at the bottom of the mating structure, and a third limiting surface and a fourth limiting surface are formed on opposite sides of the second limiting portion. When the adjusting component rotates to the first angle, the first limiting surface abuts against the third limiting surface; when the adjusting component rotates to the second angle, the second limiting surface abuts against the fourth limiting surface. By tightly abutting the first and third limiting surfaces when the adjusting component rotates to the first angle, a first precise physical stop point is formed, limiting the maximum value of the grinding gap, thereby limiting the maximum possible coffee powder particle size. When rotated to the second angle, the second and fourth limiting surfaces abut against each other, forming a second precise physical stop point, limiting the minimum value of the grinding gap, thereby limiting the minimum possible coffee powder particle size.

[0013] In one embodiment, the adjustment assembly includes an adjusting member, a connecting member, and a drive gear assembly. The adjusting member is disposed on the mating structure, and the adjusting member, the connecting member, and the drive gear assembly are connected sequentially. The adjusting member can drive the drive gear assembly to rotate. The connecting member forms the first limiting portion, and the drive gear assembly is configured to be driveably connected to the coffee grinding device. Specifically, the lifting and adjusting structure of the coffee grinding device has teeth on its outer side that mesh with the drive gear assembly. This design gives the engagement between the drive gear assembly and the lifting and adjusting structure a self-locking characteristic, allowing the adjustment assembly to automatically lock after adjusting to any angle, thus enabling more precise adjustment of the coffee powder particle size.

[0014] In one embodiment, the bean hopper body has a bean outlet communicating with the bean storage chamber. The bottom wall of the bean storage chamber extends toward the bean outlet. It also includes a distribution structure disposed on the mating structure and the bean hopper body. The distribution structure is located on the bottom wall of the bean storage chamber and is used to divide the bean storage chamber into at least two guiding paths extending toward the bean outlet. By dividing and guiding the flow path of the coffee beans through the distribution structure, the coffee beans can be automatically conveyed toward the bean outlet, effectively preventing the coffee beans from accumulating or clogging around the mating structure, thus ensuring smooth and stable bean dispensing.

[0015] In one embodiment, the cross-section of the dispensing structure is teardrop-shaped or triangular. By using a teardrop-shaped or triangular cross-section and positioning the tip of the dispensing structure away from the bean outlet, the coffee beans can be efficiently diverted, guiding them naturally along the smooth conveying paths on both sides towards the bean outlet. This greatly reduces the possibility of coffee beans getting stuck or forming dead zones in front of the dispensing structure.

[0016] In one embodiment, the material distribution structure and the mating structure are integrated. This integration significantly enhances the overall mechanical strength of the structure, reduces the number of parts and assembly steps, improves production efficiency and product consistency, and lowers manufacturing costs.

[0017] A coffee machine comprising: the aforementioned bean hopper structure.

[0018] The second aspect of this application discloses a coffee machine in which the portion of the bean hopper assembly located outside the housing assembly and the lid assembly are made of transparent material, allowing for direct visualization of the remaining coffee beans and avoiding frequent lid opening. By limiting the stroke of the adjustment component, the maximum and minimum particle size of the coffee powder can be controlled. The dispensing structure ensures smooth bean dispensing and improves dispensing efficiency. Attached Figure Description

[0043] 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.

[0044] 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.

[0045] Example 1

[0046] like Figures 1-17 As shown, this embodiment discloses a bean hopper structure, including: a shell assembly 1, the shell assembly 1 having a mounting cavity 101; a bean hopper assembly 2, the bean hopper assembly 2 being disposed on the shell assembly 1 and located at the mounting cavity 101, a portion of the bean hopper assembly 2 being located outside the shell assembly 1, the bean hopper assembly 2 having a bean storage cavity 201, the portion of the bean hopper assembly 2 located outside the shell assembly 1 having an opening 202, the opening 202 communicating with the bean storage cavity 201; a cover assembly 3, the cover assembly 3 being disposed on the bean hopper assembly 2 and located at the opening 202; at least a portion of the bean hopper assembly 2 located outside the shell assembly 1 being made of a transparent material; and / or, at least a portion of the cover assembly 3 being made of a transparent material.

[0047] The first aspect of this application discloses a bean hopper structure. By using a transparent material for the portion of the bean hopper assembly 2 located outside the housing or a portion of the cover assembly 3, a viewing window is created to directly observe the bean storage chamber 201, allowing the user to clearly see the amount and status of coffee beans inside at any time. This design makes it easy to determine when to replenish coffee beans, and once the remaining amount is sufficient, the user no longer needs to perform the tedious and potentially futile process of opening, checking, and closing the machine, simplifying the user's operation and making daily use of the coffee machine easier and more user-friendly. Furthermore, fewer opening and closing cycles help maintain a more stable and suitable storage environment inside the bean storage chamber 201, minimizing contact between the coffee beans and external humid air, thereby more effectively preserving the freshness, flavor, and quality of the coffee beans. The fact that part of the bean hopper assembly 2 is located outside the housing assembly 1 further increases the viewing area, enhancing the ability to intuitively observe the remaining amount of coffee beans.

[0048] In addition to the features of the above embodiments, this embodiment further specifies that the bean hopper component 2 is made of transparent material. By making the entire bean hopper component 2 of transparent material, the overall material of the bean hopper component 2 is uniform, facilitating processing and manufacturing, reducing processing complexity, and thus effectively improving production efficiency and product consistency.

[0049] In addition to the features of the above embodiments, this embodiment further specifies that the cover assembly 3 is made of a transparent material. Because the cover assembly 3 is made of a transparent material, the user can directly observe the remaining amount of coffee beans inside the bean storage chamber 201 through the transparent cover assembly 3 without opening the cover, achieving instant viewing without any operation. This not only greatly improves the convenience of use but also minimizes the contact between the coffee beans and air, thereby better maintaining the freshness and quality of the coffee beans.

[0050] like Figures 8-10 As shown, in addition to the features of the above embodiments, this embodiment further specifies that: the bean hopper assembly 2 is provided with an assembly space 203, the assembly space 203 is connected to the bean storage chamber 201, and the bean hopper structure also includes an adjustment component 4, which is disposed on the bean hopper assembly 2 and located at the assembly space 203. The adjustment component 4 is configured to be drivenly connected to the grinding device 5 for adjusting the particle size of the coffee powder ground by the grinding device 5. By positioning the adjustment component 4 at the assembly space 203, the adjustment component 4 can operate stably. By being drivenly connected to the grinding device 5, the particle size of the coffee powder ground by the grinding device 5 can be controlled by operating the adjustment component 4, ensuring that the particle size of the coffee powder meets the user's needs.

[0051] like Figure 16 and Figure 17As shown, in addition to the features of the above embodiments, this embodiment further specifies that: the grinding device 5 includes an outer grinding blade assembly 51 and an inner grinding blade assembly 52; the grinding device 5 is provided with a powder outlet 501; a grinding gap 502 is formed between the outer grinding blade assembly 51 and the inner grinding blade assembly 52; the grinding gap 502 communicates with the powder outlet 501; the outer grinding blade assembly 51 includes an outer blade structure 511 and a lifting adjustment structure 512; the lifting adjustment structure 512 is tractively connected to the adjustment component 4; the lifting adjustment structure 512 can rotate under the control of the adjustment component 4; the outer blade structure 511 is movably disposed on the lifting adjustment structure 512; when the lifting adjustment structure 512 rotates, it can drive the outer blade structure 511 to move toward or away from the inner grinding blade assembly 52. By adjusting the component 4 and the lifting adjustment structure 512 of the grinding device 5, the user can control the rotation of the lifting adjustment structure 512 through the component 4. The outer blade structure 511 moves toward or away from the inner grinding blade assembly 52, thereby adjusting the grinding gap 502 between the outer grinding blade assembly 51 and the inner grinding blade assembly 52. ​​By adjusting the size of the grinding gap 502, the coarseness of the coffee beans can be precisely controlled to meet the needs of different coffee making processes.

[0052] like Figures 8-10 As shown, in addition to the features of the above embodiments, this embodiment further specifies that: the bean hopper assembly 2 includes a bean hopper body 21 and a mating structure 22. The bean hopper body 21 is disposed on the housing assembly 1 and located at the mounting cavity 101. The bean hopper body 21 has the bean storage cavity 201 and the opening 202. The mating structure 22 is disposed on the bean hopper body 21 and located within the bean storage cavity 201. The mating structure 22 has the assembly space 203. The adjusting component 4 is movably disposed on the mating structure 22 and located at the assembly space 203. By movably disposing of the adjusting component 4 on the mating structure 22 and located at the assembly space 203, the degree of freedom of the adjusting component 4 can be effectively restricted, allowing the adjusting component 4 to only perform movements such as rotation, thereby enabling the adjusting component 4 to precisely control the rotation of the lifting and lowering adjusting structure 512.

[0053] like Figure 4 and Figure 17As shown, in addition to the features of the above embodiments, this embodiment further specifies that: the adjusting component 4 can rotate relative to the mating structure 22, and the adjusting component 4 can rotate relative to the mating structure 22 by at least a first angle and a second angle. When the adjusting component 4 rotates to the first angle, the particle size of the coffee powder ground by the grinding device 5 is greater than that when the adjusting component 4 rotates to the second angle. By allowing the adjusting component 4 to rotate relative to the mating structure 22, and by allowing the adjusting component 4 to rotate at different angles to correspond to different coffee powder particle sizes, a precise and predictable grinding adjustment function is achieved. Specifically, when the adjusting component 4 rotates to the first angle, the grinding gap 502 increases, and when the adjusting component 4 rotates to the second angle, the grinding gap 502 decreases, which can effectively adjust the particle size of the coffee powder.

[0054] like Figure 7 and Figures 11-14 As shown, in addition to the features of the above embodiments, this embodiment further specifies that: a first limiting part 44 is formed on the adjusting component 4, a first limiting surface 401 and a second limiting surface 402 are formed on opposite sides of the first limiting part 44, a second limiting part 221 is formed at the bottom of the mating structure 22, a third limiting surface 204 and a fourth limiting surface 205 are formed on opposite sides of the second limiting part 221, when the adjusting component 4 rotates at the first angle, the first limiting surface 401 abuts against the third limiting surface 204, and when the adjusting component 4 rotates at the second angle, the second limiting surface 402 abuts against the fourth limiting surface 205. When the adjustment component 4 is rotated to the first angle, the first limiting surface 401 and the third limiting surface 204 abut together, forming the first precise physical stop point, which limits the maximum value of the grinding gap 502, thereby limiting the maximum particle size of the coffee powder that can be produced; when rotated to the second angle, the second limiting surface 402 abuts together with the fourth limiting surface 205, forming the second precise physical stop point, which limits the minimum value of the grinding gap 502, thereby limiting the minimum particle size of the coffee powder that can be produced.

[0055] like Figure 8 , Figure 12 and Figure 15As shown, in addition to the features of the above embodiments, this embodiment further specifies that: the adjusting component 4 includes an adjusting member 41, a connecting member 42, and a drive gear assembly 43. The adjusting member 41 is disposed on the mating structure 22. The adjusting member 41, the connecting member 42, and the drive gear assembly 43 are connected in sequence. The adjusting member 41 can drive the drive gear assembly 43 to rotate. The first limiting part 44 is formed on the connecting member 42. The drive gear assembly 43 is configured to be drive-connected to the coffee grinding device 5. Specifically, the lifting adjustment structure 512 of the coffee grinding device 5 has teeth on its outer side that mesh with the drive gear assembly 43. This design gives the engagement between the drive gear assembly 43 and the lifting adjustment structure 512 a self-locking characteristic. The adjusting component 4 can automatically lock after adjusting any angle, enabling more precise adjustment of the coffee powder particle size.

[0056] like Figure 8 and Figure 13 As shown, in addition to the features of the above embodiments, this embodiment further specifies that: the bean hopper body 21 is provided with a bean outlet 206 communicating with the bean storage cavity 201, the bottom wall of the bean storage cavity 201 extends toward the bean outlet 206, and also includes a distribution structure 6. The distribution structure 6 is disposed on the mating structure 22 and the bean hopper body 21, and is located at the bottom wall of the bean storage cavity 201. The distribution structure 6 is used to divide the bean storage cavity 201 into at least two guiding paths extending toward the bean outlet 206. By setting the distribution structure 6, the flow path of the coffee beans is diverted and guided, so that the coffee beans can be automatically conveyed toward the bean outlet 206, effectively avoiding the accumulation or blockage of coffee beans around the mating structure 22, and ensuring the smoothness and stability of bean dispensing.

[0057] like Figure 9 and Figure 10 As shown, in addition to the features of the above embodiments, this embodiment further specifies that the cross-section of the dispensing structure 6 is teardrop-shaped or triangular. By having the cross-section of the dispensing structure 6 be teardrop-shaped or triangular and the tip of the dispensing structure 6 positioned away from the bean outlet 206, the coffee beans can be efficiently diverted, guiding them naturally along the smooth conveying paths on both sides towards the bean outlet 206, greatly reducing the possibility of coffee beans being blocked or forming dead zones in front of the dispensing structure 6.

[0058] like Figure 9 and Figure 10As shown, in addition to the features of the above embodiments, this embodiment further specifies that the material distribution structure 6 and the mating structure 22 are integrated. By integrating the material distribution structure 6 and the mating structure 22, the mechanical strength of the overall structure is significantly enhanced, and the number of parts and assembly steps is reduced, thereby improving production efficiency and product consistency, and lowering manufacturing costs.

By limiting the stroke of the adjustment assembly 4, the maximum and minimum particle size of the coffee powder can be controlled. The dispensing structure 6 ensures smooth bean dispensing and improves dispensing efficiency.

[0062] The above embodiments only illustrate several implementation methods of this utility model, and their descriptions are relatively specific and detailed, but they should not be construed as limiting the scope of the utility model patent.
