Description

Technical Field

[0001] This utility model relates to the field of coffee grinders, and in particular to a blade gap adjustment structure and a coffee grinder. Background Technology

[0002] A coffee grinder is an essential piece of equipment for grinding coffee beans into powder. The gap between the upper and lower blades of the grinder determines the size of the coffee powder particles. However, traditional grinders generally lack a mechanism for adjusting the gap between the upper and lower blades, or the existing adjustment mechanism is ineffective, causing inconvenience to users. Therefore, further improvements to the grinder's structure are needed. Utility Model Content

[0003] Therefore, it is necessary to provide a blade gap adjustment structure and a coffee grinder to address the problem that traditional coffee grinders generally do not have a structure for adjusting the gap between the upper and lower blades, or the structure for adjusting the gap between the upper and lower blades has poor adjustment effect, which causes inconvenience to users.

[0004] A cutter head gap adjustment structure includes: a housing assembly; a first cutter head assembly disposed on the housing assembly; a driving structure disposed on the housing assembly; an adjustment structure connected to the driving structure, the driving structure being capable of driving the adjustment structure to move relative to the housing assembly; and a second cutter head assembly disposed on the adjustment structure, wherein when the adjustment structure moves relative to the housing assembly, the second cutter head assembly has at least a first position and a second position, wherein when the second cutter head assembly is located at the first position, the gap between the second cutter head assembly and the first cutter head assembly is L1, and when the second cutter head assembly is located at the second position, the gap between the second cutter head assembly and the first cutter head assembly is L2, wherein L2 is greater than L1.

[0005] The first aspect of this application discloses a blade gap adjustment structure. When the adjustment structure moves relative to the housing assembly, the second blade assembly has at least a first position and a second position, meaning the second blade assembly can move vertically relative to the first blade assembly. This adjusts the gap between the second and first blade assemblies, making the size of the coffee powder particles output from the gap controllable. Users can adjust the particle size of the coffee powder to create different coffee flavors according to their own taste. The driving structure can be a knob, a cylinder, or other driving component, which can stably drive the adjustment structure to move. Furthermore, when the driving structure stops, the adjustment structure is stably fixed in the corresponding position, and the second blade assembly also stops moving. Therefore, the gap between the second and first blade assemblies remains stable, ensuring uniformity in the coarseness of the coffee beans during grinding.

[0006] In one embodiment, the drive structure is at least rotatable relative to the housing assembly in a first direction and a second direction, the first direction and the second direction being opposite. When the drive structure rotates in the first direction, the second cutter head assembly moves towards the first cutter head assembly, and when the drive structure rotates in the second direction, the second cutter head assembly moves away from the first cutter head assembly. The drive structure can rotate clockwise and counterclockwise, thereby controlling the up-and-down movement of the second cutter head assembly, adjusting the gap between the second and first cutter head assemblies, and quickly achieving a suitable grinding fineness. This cutter head gap method is relatively simple, has wider applicability, and can be suitable for a wider range of customers.

[0007] In one embodiment, a bearing assembly is further included, disposed on the adjusting structure and / or the second cutter head assembly, and sandwiched between the adjusting structure and the second cutter head assembly. By sandwiching the bearing assembly between the adjusting structure and the second cutter head assembly, the frictional resistance between the two assemblies is reduced, resulting in smoother rotation of the second cutter head assembly. Furthermore, it ensures a more stable relative position between the adjusting structure and the second cutter head assembly.

[0008] In one embodiment, the adjustment structure includes a support member, a first movable block, and a second movable block. The support member is connected to the drive structure. The first movable block is disposed on the support member and is movable relative to the support member. The second movable block is disposed on the first movable block and is movable relative to the first movable block. When the second movable block moves relative to the first movable block, the second cutter head assembly moves toward or away from the first cutter head assembly. By moving the first movable block relative to the support member, moving the second movable block relative to the first movable block, and moving the second cutter head assembly along with the movement of the second movable block, finer cutter head gap adjustment can be achieved. Furthermore, the arrangement of the first and second movable blocks results in a relatively small workload on each movable block, reducing the wear rate.

[0009] In one embodiment, the drive structure is capable of rotating at least a first angle and a second angle relative to the housing assembly. When the first moving block moves relative to the support member, it has at least a third and a fourth position. When the second moving block moves relative to the first moving block, it has at least a fifth and a sixth position. When the drive structure rotates the first angle, the first moving block is located at the third position, the second moving block is located at the fifth position, and the second burr assembly is located at the first position. When the drive structure rotates the second angle, the first moving block is located at the fourth position, the second moving block is located at the sixth position, and the second burr assembly is located at the second position. The burr gap is adjusted through the sequential power control of the drive structure, the first moving block, the second moving block, and the second burr assembly. Users can accurately rotate the drive structure to a specific angle according to a standard procedure to quickly obtain the required coffee powder particle size, ensuring the stability of coffee quality.

[0010] In one embodiment, a first inclined surface is formed on the first moving block, and a second inclined surface is formed on the second moving block, with the second inclined surface abutting against the first inclined surface. By the contact between the first inclined surface of the first moving block and the second inclined surface of the second moving block, the height of the second moving block at the first inclined surface changes after the first moving block moves, thereby allowing the second moving block to move up and down to adjust the cutter head gap. This adjustment method is stable and reliable.

[0011] In one embodiment, the direction in which the first moving block moves relative to the support intersects the direction in which the second moving block moves relative to the first moving block. Because the direction in which the first moving block moves relative to the support intersects the direction in which the second moving block moves relative to the first moving block, the second moving block can move up and down when the first moving block moves on a horizontal plane. This up-and-down movement of the second moving block adjusts the cutter head gap, resulting in a stable and reliable adjustment method.

[0012] In one embodiment, a first elastic element is further included, with its two ends abutting against the first movable block and the support member, respectively. The first elastic element applies a force toward the drive structure to the first movable block. By having its two ends abut against the first movable block and the support member, the first elastic element applies an additional force to the first movable block, making its movement smoother.

[0013] In one embodiment, the first moving block has a first adapter hole, a first thread is formed on the wall of the first adapter hole, and a second thread is formed on the drive structure, the second thread engaging with the first thread. By adapting the first thread in the first adapter hole to the second thread in the drive structure, the first moving block moves in one direction when the drive structure screws into the first adapter hole to a greater depth, and moves in the opposite direction when the drive structure screws into the second adapter hole to a smaller depth. This design enables stable adjustment of the cutter head gap.

[0014] In one embodiment, a first adapter column is formed on the support member, and the first adapter column has a first adapter channel. The drive structure passes through the first adapter channel and connects to the first movable block after passing through the first adapter channel. By connecting the drive structure to the first movable block after passing through the first adapter channel, an additional support point is provided for the drive structure, resulting in better torsional resistance and more efficient knob-driven movement of the first movable block.

[0015] In one embodiment, the drive structure includes a knob assembly, a first transmission rod, and a connector. The knob assembly is disposed on the housing assembly, the first transmission rod is disposed on the knob assembly and screwed to the adjustment structure, and the connector is disposed on the knob assembly and / or the first transmission rod, connecting the knob assembly and the first transmission rod. Both the knob assembly and the first transmission rod are rotatable relative to the housing assembly. Because the knob assembly is disposed on and outside the housing assembly, the user can directly rotate the knob assembly from outside the grinder, making operation simple and convenient. The power transmission through the knob assembly and the first transmission rod enables the adjustment structure to move, resulting in high power transmission efficiency.

[0016] In one embodiment, a support structure and a second elastic member are further included. The support structure is disposed on the second cutter head assembly and located at the end of the second cutter head assembly away from the adjustment structure. The two ends of the second elastic member abut against the support structure and the second cutter head assembly, respectively. By abutting against the support structure and the second cutter head assembly, the second elastic member applies a force to the second cutter head assembly, making the downward movement of the second cutter head assembly smoother.

[0017] In one embodiment, the first cutter head assembly includes a first cutter head bracket and a first cutter head structure. The first cutter head bracket is disposed on the housing assembly, and the first cutter head structure is disposed on the first cutter head bracket. The first cutter head bracket provides more stable support for the first cutter head structure, ensuring the stability of the first cutter head structure and facilitating precise grinding of coffee beans.

[0018] In one embodiment, the second cutter head assembly includes a second cutter head bracket and a second cutter head structure. The second cutter head bracket is disposed on the housing assembly, and the second cutter head structure is disposed on the second cutter head bracket. The second cutter head bracket provides more stable support for the second cutter head structure, ensuring its stability and facilitating precise grinding of coffee beans.

[0019] In one embodiment, a cutter head housing is further included, which is disposed on the housing assembly, with both the first cutter head assembly and the second cutter head assembly located inside the cutter head housing. By having both the first and second cutter head assemblies located inside the cutter head housing, the first and second cutter head assemblies can be protected.

[0020] In one embodiment, the first movable block is provided with a second adapter hole and an adapter groove. The adapter groove communicates with the second adapter hole, and the diameter or length of the adapter groove is greater than the diameter of the second adapter hole. It also includes a second adapter post, which is disposed on the support member and / or the housing assembly. The second adapter post has a second adapter channel, through which the driving structure passes. After passing through the second adapter channel, the driving structure engages with the second adapter hole. A protrusion is formed on one end of the driving structure located at the second adapter hole, and the protrusion movably engages with the adapter groove. A third thread is formed on the channel wall of the second adapter channel, and a fourth thread is formed on the driving structure, which engages with the third thread. Through the movable engagement of the protrusion of the driving structure with the adapter groove of the first movable block, the entire driving structure can rotate relative to the housing assembly. The protrusion is annular or fan-shaped. The fourth thread of the drive structure engages with the third thread on the channel wall of the second adapter channel. Due to the self-locking characteristic of the thread, the movement of the drive structure can be stopped at any time and the position of the drive structure can be fixed immediately. Thus, the movement of the second cutter head assembly can be stopped at any time, and the gap between the second cutter head assembly and the first cutter head assembly can be fixed after adjustment, ensuring the uniformity of coffee powder grinding.

[0021] In one embodiment, the drive structure includes a drive motor and a second transmission rod. The drive motor is mounted on the housing assembly, and the second transmission rod is driveably connected to the drive motor. The second transmission rod is screwed to the adjustment structure, and the drive motor can drive the second transmission rod to rotate relative to the housing assembly. This motor-driven adjustment method, with the second transmission rod connected to the drive motor, effectively improves power transmission efficiency, enhances adjustment effect, and achieves a high degree of automation.

[0022] A coffee grinder includes: the aforementioned blade gap adjustment structure.

[0023] The second aspect of this application discloses a coffee grinder that maintains a stable blade gap during grinding through a blade gap adjustment structure. This helps to grind coffee beans into a uniform size, avoiding situations where some coffee powder is too fine or too coarse. The uniform size of the coffee powder allows for more thorough contact with water during brewing, ensuring better coffee quality. Furthermore, the adjustment method is simple and convenient, making it suitable for a wider range of customers. Attached Figure Description

[0045] 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.

[0046] 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.

[0047] Example 1

[0048] like Figure 1-3 As shown, this embodiment discloses a cutter head gap adjustment structure, including: a housing assembly 1; a first cutter head assembly 2, the first cutter head assembly 2 being disposed on the housing assembly 1; a driving structure 3, the driving structure 3 being disposed on the housing assembly 1; an adjustment structure 4, the adjustment structure 4 being connected to the driving structure 3, the driving structure 3 being capable of driving the adjustment structure 4 to move relative to the housing assembly 1; and a second cutter head assembly 5, the second cutter head assembly 5 being disposed on the adjustment structure 4, wherein when the adjustment structure 4 moves relative to the housing assembly 1, the second cutter head assembly 5 has at least a first position and a second position, the distance between the second cutter head assembly 5 and the first cutter head assembly 2 is L1 when the second cutter head assembly 5 is located in the first position, and the distance between the second cutter head assembly 5 and the first cutter head assembly 2 is L2 when the second cutter head assembly 5 is located in the second position, wherein L2 is greater than L1.

[0049] The first aspect of this application discloses a blade gap adjustment structure. When the adjustment structure 4 moves relative to the housing assembly 1, the second blade assembly 5 has at least a first position and a second position, meaning the second blade assembly 5 can move up and down relative to the first blade assembly 2, thereby adjusting the gap between the second blade assembly 5 and the first blade assembly 2. This allows for controllable particle size of the coffee powder output from the gap, enabling users to adjust the particle size of the coffee powder to create different coffee flavors according to their own taste. The drive structure 3, which can be a knob, a cylinder, or other drive component, can stably drive the adjustment structure 4 to move. Moreover, when the drive structure 3 stops, the adjustment structure 4 is also stably fixed in the corresponding position, and the second blade assembly 5 also stops moving. Therefore, the gap between the second blade assembly 5 and the first blade assembly 2 remains stable, ensuring uniformity in the coarseness of the coffee beans during the grinding process.

[0050] like Figure 1-3 As shown, in addition to the features of the above embodiments, this embodiment further specifies that: the driving structure 3 is at least rotatable relative to the housing assembly 1 in a first direction and a second direction, the first direction and the second direction being opposite; when the driving structure 3 rotates in the first direction, the second cutter head assembly 5 moves towards the first cutter head assembly 2; when the driving structure 3 rotates in the second direction, the second cutter head assembly 5 moves away from the first cutter head assembly 2. The driving structure 3 can rotate in clockwise and counterclockwise directions, thereby controlling the up-and-down movement of the second cutter head assembly 5, adjusting the gap between the second cutter head assembly 5 and the first cutter head assembly 2, and quickly achieving a suitable grinding fineness. This cutter head gap method is relatively simple, has wider applicability, and can be suitable for a wider range of customers.

[0051] like Figure 3 and Figure 5 As shown, in addition to the features of the above embodiments, this embodiment further includes a bearing assembly 6, which is disposed on the adjusting structure 4 and / or the second cutter head assembly 5, and is sandwiched between the adjusting structure 4 and the second cutter head assembly 5. By sandwiching the bearing assembly 6 between the adjusting structure 4 and the second cutter head assembly 5, the frictional resistance between the adjusting structure 4 and the second cutter head assembly 5 is reduced, resulting in smoother rotation of the second cutter head assembly 5. Furthermore, it ensures a more stable relative position between the adjusting structure 4 and the second cutter head assembly 5.

[0052] like Figure 5 and Figure 9As shown, in addition to the features of the above embodiments, this embodiment further specifies that: the adjustment structure 4 includes a support member 41, a first moving block 42, and a second moving block 43. The support member 41 is connected to the drive structure 3. The first moving block 42 is disposed on the support member 41 and is movable relative to the support member 41. The second moving block 43 is disposed on the first moving block 42 and is movable relative to the first moving block 42. When the second moving block 43 moves relative to the first moving block 42, the second cutter head assembly 5 moves toward or away from the first cutter head assembly 2. By the movement of the first moving block 42 relative to the support member 41, the movement of the second moving block 43 relative to the first moving block 42, and the movement of the second cutter head assembly 5 along with the movement of the second moving block 43, finer cutter head gap adjustment can be achieved. Moreover, the arrangement of the first moving block 42 and the second moving block 43 makes the workload borne by each moving block relatively small, which can reduce the wear rate.

[0053] like Figure 5 and Figure 9 As shown, in addition to the features of the above embodiments, this embodiment further specifies that: the drive structure 3 can rotate at least a first angle and a second angle relative to the housing assembly 1; the first moving block 42 has at least a third position and a fourth position when moving relative to the support member 41; the second moving block 43 has at least a fifth position and a sixth position when moving relative to the first moving block 42; when the drive structure 3 rotates at the first angle, the first moving block 42 is located at the third position, the second moving block 43 is located at the fifth position, and the second blade assembly 5 is located at the first position; when the drive structure 3 rotates at the second angle, the first moving block 42 is located at the fourth position, the second moving block 43 is located at the sixth position, and the second blade assembly 5 is located at the second position. The blade gap is adjusted through the sequential power control of the drive structure 3, the first moving block 42, the second moving block 43, and the second blade assembly 5. Users can accurately rotate the drive structure 3 to a specific angle according to a standard procedure to quickly obtain the required coffee powder particle size, ensuring the stability of coffee quality.

[0054] like Figure 5 and Figure 9As shown, in addition to the features of the above embodiments, this embodiment further specifies that: a first inclined surface 401 is formed on the first moving block 42, and a second inclined surface 402 is formed on the second moving block 43, with the second inclined surface 402 abutting against the first inclined surface 401. By abutting the first inclined surface 401 of the first moving block 42 against the second inclined surface 402 of the second moving block 43, the height of the second moving block 43 at the first inclined surface 401 changes after the first moving block 42 moves, thereby allowing the second moving block 43 to move up and down to adjust the cutter head gap. The adjustment method is stable and reliable.

[0055] like Figure 5 and Figure 9 As shown, in addition to the features of the above embodiments, this embodiment further specifies that: the direction in which the first moving block 42 moves relative to the support member 41 intersects the direction in which the second moving block 43 moves relative to the first moving block 42. Because the direction in which the first moving block 42 moves relative to the support member 41 intersects the direction in which the second moving block 43 moves relative to the first moving block 42, the second moving block 43 can move up and down when the first moving block 42 moves on the horizontal plane. This allows the second moving block 43 to adjust the cutter head gap by moving up and down, and the adjustment method is stable and reliable.

[0056] like Figure 5 As shown, in addition to the features of the above embodiments, this embodiment further includes a first elastic member 44, whose two ends abut against the first moving block 42 and the support member 41, respectively. The first elastic member 44 is used to apply a force toward the driving structure 3 to the first moving block 42. By having its two ends abut against the first moving block 42 and the support member 41, the first elastic member 44 applies an additional force to the first moving block 42, making the movement of the first moving block 42 smoother.

[0057] like Figure 5 As shown, in addition to the features of the above embodiments, this embodiment further specifies that: the first moving block 42 is provided with a first adapter hole 403, a first thread is formed on the wall of the first adapter hole 403, and a second thread is formed on the driving structure 3, the second thread engaging with the first thread. By adapting the first thread formed on the first adapter hole 403 to the second thread formed on the driving structure 3, the first moving block 42 moves in one direction when the driving structure 3 screws into the first adapter hole 403 to a greater depth, and moves in the opposite direction when the driving structure 3 screws into the second adapter hole 405 to a smaller depth. This design enables stable adjustment of the cutter head gap.

[0058] like Figure 4 and Figure 5As shown, in addition to the features of the above embodiments, this embodiment further specifies that: a first adapting column 411 is formed on the support member 41, the first adapting column 411 is provided with a first adapting channel 404, the driving structure 3 passes through the first adapting channel 404, and the driving structure 3 is connected to the first moving block 42 after passing through the first adapting channel 404. By connecting the driving structure 3 to the first moving block 42 after passing through the first adapting channel 404, an additional support point can be provided for the driving structure 3, thereby improving the torsional resistance of the driving structure 3 and enabling the driving structure 3 to more effectively drive the first moving block 42 to move.

[0059] like Figure 4 , Figure 5 and Figure 9 As shown, in addition to the features of the above embodiments, this embodiment further defines the following: the drive structure 3 includes a knob assembly 31, a first transmission rod 32, and a connector 33. The knob assembly 31 is disposed on the housing assembly 1, the first transmission rod 32 is disposed on the knob assembly 31, and the first transmission rod 32 is screwed to the adjustment structure 4. The connector 33 is disposed on the knob assembly 31 and / or the first transmission rod 32, and the connector 33 is used to connect the knob assembly 31 and the first transmission rod 32. Both the knob assembly 31 and the first transmission rod 32 are rotatable relative to the housing assembly 1. Because the knob assembly 31 is disposed on the housing assembly 1 and located outside the housing assembly 1, the user can directly rotate the knob assembly 31 from outside the grinder, making operation simple and convenient. The adjustment structure 4 moves through the power transmission of the knob assembly 31 and the first transmission rod 32, resulting in high power transmission efficiency.

[0060] like Figure 3 As shown, in addition to the features of the above embodiments, this embodiment further includes a support structure 7 and a second elastic member 8. The support structure 7 is disposed on the second cutter head assembly 5 and is located at the end of the second cutter head assembly 5 away from the adjusting structure 4. The two ends of the second elastic member 8 abut against the support structure 7 and the second cutter head assembly 5, respectively. By abutting against the support structure 7 and the second cutter head assembly 5, the second elastic member 8 applies a force to the second cutter head assembly 5, making the downward movement of the second cutter head assembly 5 smoother.

[0061] like Figure 8As shown, in addition to the features of the above embodiments, this embodiment further specifies that: the first blade assembly 2 includes a first blade support 21 and a first blade structure 22, the first blade support 21 is disposed on the housing assembly 1, and the first blade structure 22 is disposed on the first blade support 21. The first blade support 21 provides more stable support for the first blade structure 22, ensuring the stability of the first blade structure 22 and facilitating precise grinding of coffee beans.

[0062] like Figure 8 As shown, in addition to the features of the above embodiments, this embodiment further specifies that: the second cutter head assembly 5 includes a second cutter head bracket 51 and a second cutter head structure 52, the second cutter head bracket 51 is disposed on the housing assembly 1, and the second cutter head structure 52 is disposed on the second cutter head bracket 51. The arrangement of the second cutter head bracket 51 provides more stable support for the second cutter head structure 52, ensuring the stability of the second cutter head structure 52 and facilitating precise grinding of coffee beans.

[0063] like Figure 7-8 As shown, in addition to the features of the above embodiments, this embodiment further includes a cutter head housing 9, which is disposed on the housing assembly 1, and the first cutter head assembly 2 and the second cutter head assembly 5 are both located inside the cutter head housing 9. By having both the first cutter head assembly 2 and the second cutter head assembly 5 located inside the cutter head housing 9, the first cutter head assembly 2 and the second cutter head assembly 5 can be protected.

[0064] Example 2

[0065] like Figure 6As shown, the first movable block 42 is provided with a second adapter hole 405 and an adapter groove 406. The adapter groove 406 communicates with the second adapter hole 405, and the diameter or length of the adapter groove 406 is greater than the diameter of the second adapter hole 405. It also includes a second adapter post 412, which is disposed on the support member 41 and / or the housing assembly 1. The second adapter post 412 is provided with a second adapter channel 407. The driving structure 3 passes through the second adapter channel 407 and engages with the second adapter hole 405 after passing through the second adapter channel 407. A protrusion 34 is formed on one end of the driving structure 3 located at the second adapter hole 405. The protrusion 34 is movably engaged with the adapter groove 406. A third thread is formed on the channel wall of the second adapter channel 407, and a fourth thread is formed on the driving structure 3. The fourth thread engages with the third thread. The drive structure 3's protrusion 34 engages with the adapter groove 406 of the first moving block 42, allowing the drive structure 3 to rotate relative to the housing assembly 1. The protrusion 34 is either annular or fan-shaped. The drive structure 3's fourth thread engages with the third thread on the channel wall of the second adapter channel 407. Due to the thread's self-locking characteristic, the drive structure 3 can stop moving at any time, and its position is immediately fixed. This allows the second cutter head assembly 5 to stop moving at any time, ensuring that the gap between the second cutter head assembly 5 and the first cutter head assembly 2 is adjusted and fixed, thus guaranteeing the uniformity of coffee powder grinding.

[0066] Example 3

[0067] The drive structure 3 includes a drive motor and a second transmission rod. The drive motor is mounted on the housing assembly 1, and the second transmission rod is driven by the drive motor. The second transmission rod is also screwed to the adjustment structure 4. The drive motor can drive the second transmission rod to rotate relative to the housing assembly 1. This motor-driven adjustment method, with the second transmission rod connected to the drive motor, effectively improves power transmission efficiency, enhances adjustment effect, and achieves a high degree of automation.

[0068] Example 4

[0069] like Figure 10 As shown, this embodiment discloses a coffee grinder, including the aforementioned blade gap adjustment structure 100.

[0070] The second aspect of this application discloses a coffee grinder in which the blade gap adjustment structure 100 maintains a stable gap during grinding, helping to ensure that the coffee beans are ground to a uniform size and avoiding some coffee powder being too fine or too coarse. The uniform size of the coffee powder particles allows for more thorough contact with water during brewing, ensuring better coffee quality. Furthermore, the adjustment method is simple and convenient, making it suitable for a wider range of customers.

[0071] 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. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of this utility model, and these all fall within the protection scope of this utility model. Therefore, the protection scope of this utility model patent should be determined by the appended claims.
