Description

Technical Field

[0001] This utility model relates to the technical field of coffee processing equipment, and in particular to a silver husk collection device and a coffee roaster. Background Technology

[0002] During the coffee bean roasting process, the silverskin on the surface of the coffee beans will fall off due to the high temperature, forming a large amount of lightweight coffee silverskin. If these silverskins are not collected in time, they will be dispersed into the roasting environment by the airflow, not only contaminating the equipment and operating space, but also potentially being inhaled and harming human health. At the same time, silverskins entering the internal components of the roaster (such as the fan and heating element) may affect the normal operation of the equipment and even cause safety hazards.

[0003] The existing silver collection devices have the following shortcomings: the opening design of the silver box is unreasonable, causing some silver to escape with the airflow and making it impossible to effectively intercept; the silver box is fixedly connected to the device body, making disassembly difficult, and the internal filter screen is difficult to remove and clean separately; air leakage is easy at the gaps of the device, and the airflow carrying silver is discharged directly without filtration, affecting the collection effect. Utility Model Content

[0004] This invention aims to at least partially solve one of the problems in related technologies. Therefore, one objective of this invention is to provide a silver foil collection device for achieving efficient collection, convenient cleaning, and multi-stage filtration of coffee silver foil.

[0005] A silver foil collection device, the silver foil collection device comprising: The box body has a silver box placement cavity inside; A silver foil box is detachably disposed within the silver foil box placement cavity. The silver foil box has an internal space for accommodating coffee foil. The silver foil box has a first opening, a second opening, and a third opening. The first opening and the second opening are respectively disposed on opposite side walls of the silver foil box, and the third opening is disposed at the bottom of the silver foil box. The interior of the silver foil box also contains multiple filters, which are respectively connected to the second opening and the third opening. A flip-top, pivotally connected to the housing, is used to selectively open or close the top of the silver box placement cavity; The box body is provided with an inlet that communicates with the first opening. The inlet is used to guide the airflow carrying the coffee foil into the internal space of the foil box. The second opening and the third opening are both used to guide the filtered airflow out of the foil box.

[0006] Furthermore, the box body also includes a sealing ring disposed on the flip cover, which abuts against the edge of the opening of the silver box placement cavity when the flip cover is in the closed state.

[0007] Furthermore, the flip cover is also provided with a locking assembly, which includes a switch handle, a sliding link, and a locking buckle. The edge of the box body is recessed with a locking groove, and the flip cover has a sliding hole. The switch handle is installed on the outer surface of the flip cover, and the locking buckle is connected to the inner surface of the flip cover. The two ends of the sliding link are respectively connected to the switch handle and the locking buckle and pass through the sliding hole. When the flip cover closes the top of the silver box placement cavity, the switch handle is moved to drive the locking buckle to be inserted into the locking groove.

[0008] Furthermore, a filter device receiving cavity is provided inside the box on one side of the silver box placement cavity, and the filter device receiving cavity is connected to the second opening and the third opening through the gap.

[0009] Furthermore, the filter is a removable filter that can be taken out of the silver case.

[0010] Furthermore, the filter screen is made of stainless steel.

[0011] Furthermore, the casing is made of metal or engineering plastic.

[0012] Furthermore, the sealing ring is made of silicone rubber or fluororubber.

[0013] This utility model also proposes a coffee roaster, including a roasting component and a silver husk collection device as described above. The roasting component is used to roast coffee beans and generate an airflow carrying coffee silver husks. The airflow outlet of the roasting assembly is connected to the inlet of the silver husk collection device to transport the airflow carrying the coffee silver husk from the roasting assembly to the silver husk box of the silver husk collection device.

[0014] Furthermore, the roasting bean assembly and the shell of the shavings collection device are integrated into the same housing, and the flip-top of the shavings collection device is located on the top or side surface of the housing.

[0015] The technical solutions provided in this application have the following advantages compared with the prior art: In this application, the silver foil box features a first opening for air intake and second and third openings for air exhaust. Combined with an internal filter, this design maximizes the interception of silver foil in the airflow, minimizing escape. The silver foil box is removable, allowing users to quickly empty the silver foil and clean the filter, facilitating maintenance. The internal filter (primary filtration) and the filter element (secondary filtration) within the filter housing effectively intercept fine silver foil, improving filtration accuracy. This application achieves efficient collection and convenient cleaning of coffee silver foil, ensuring the cleanliness and purity of the filtered air and enhancing the overall practicality of the coffee roaster.

[0020] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments.

[0021] In the description of this invention, it should be understood that the terms "upper", "lower", "front", "rear", "left", "right", "top", "bottom", "inner", "outer", etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings. They are only for the convenience of describing this invention and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this invention.

[0022] like Figure 1 - Figure 6 As shown, the silver foil collection device 1 provided in this application includes: Box 10, the box 10 having a silver box placement cavity 11 inside; A silver foil box 20 is detachably disposed within the silver foil box placement cavity 11. The silver foil box 20 has an internal space for accommodating coffee foil. The silver foil box 20 has a first opening 21, a second opening 22, and a third opening 23. The first opening 21 and the second opening 22 are respectively disposed on opposite side walls of the silver foil box 20. The third opening 23 is disposed at the bottom of the silver foil box 20. The interior of the silver foil box 20 is also provided with a plurality of filters 24, which are respectively connected to the second opening 22 and the third opening 23. The flip cover 30 is pivotally connected to the box body 10 and is used to selectively open or close the top of the silver box placement cavity 11; The housing 10 is provided with an inlet 12 that communicates with the first opening 21. The inlet 12 is used to guide the airflow carrying the coffee foil into the internal space of the foil box 20. The second opening 22 and the third opening 23 are both used to guide the filtered airflow out of the foil box 20.

[0023] The housing 10 is the basic load-bearing structure of the entire device. Its core function is to provide installation and positioning space for components such as the silver box 20 and the flip cover 30. Through the internal silver box placement cavity 11, it ensures that the silver box 20 can be stably placed and cooperate with other structures. The design of the inlet 12 is the "starting point" for airflow into the device. Its connection with the first opening 21 of the silver box 20 directly determines that the airflow carrying the silver can accurately enter the interior of the silver box 20, avoiding the irregular diffusion of airflow in other areas of the housing 10, and providing a prerequisite for subsequent silver interception. Compared with the simple structure and lack of targeted airflow guidance design of the housing 10 in the prior art, this housing 10, through the combination of "placement cavity + inlet 12", achieves the fixation of the silver box 20 and the directional guidance of airflow, structurally ensuring the orderly collection of silver.

[0024] The silver foil box 20 is detachably installed within the silver foil box placement cavity 11, forming a space to accommodate the silver foil. A first opening 21 (air inlet) and a second opening 22 (air outlet) are respectively opened on the opposite side walls, and a third opening 23 (auxiliary air outlet) is opened at the bottom. Multiple filters 24 are connected to the second and third openings 22 and 23. This detachable design overcomes the limitation of the existing silver foil box 20 being fixedly connected to the device body. Users can directly remove the silver foil box 20 from the placement cavity and easily empty the accumulated silver foil, solving the problems of difficult cleaning and the need to disassemble the entire structure required by traditional devices. The first opening 21 serves as an air inlet, receiving airflow introduced from the inlet 12 of the housing 10; the second opening 22 (side wall) and the third opening 23 (bottom) serve as air outlets, forming a dual air outlet path of "side outlet + bottom outlet". This design allows for a more uniform airflow distribution inside the silver foil box 20, avoiding airflow dead zones caused by a single opening, and enabling the silver foil to make more full contact with the filters 24, improving interception efficiency. The filter screen 24 is directly connected to the second and third openings 23 and is the core component for intercepting the silver foil. When the airflow flows from the inside of the silver foil box 20 to the opening, the filter screen 24 can directly block the silver foil, causing it to remain inside the silver foil box 20, thus achieving the initial separation of the silver foil from the airflow.

[0025] The flip cover 30 is pivotally connected to the housing 10 (e.g., a hinge connection) and is used to selectively open or close the top of the silver box placement cavity 11. The core function of the flip cover 30 is to provide an operating channel for the placement and removal of the silver box 20: when open, the user can directly remove the silver box 20 from the top of the placement cavity; when closed, it can fix the position of the silver box 20, preventing it from shifting due to airflow impact or vibration during device operation. The pivotal connection design (e.g., a hinge) ensures the ease of operation of the flip cover 30; the user can complete the placement and removal of the silver box 20 without completely disassembling the flip cover 30, simplifying the operation process. Compared to the complex design of existing devices that require the disassembly of multiple parts for placing and removing the silver box 20, the flip cover 30 significantly lowers the user's operating threshold and improves the ease of use of the device.

[0026] This design first overcomes the limitations of existing devices where the silver skin box 20 is fixed by using a "detachable silver skin box 20". Users can directly remove the silver skin box 20 from the placement chamber to empty the silver skin without disassembling complex parts, greatly improving the convenience of cleaning and effectively avoiding the decrease in collection efficiency caused by the accumulation of silver skin. Secondly, the "three-opening" layout of the silver skin box 20 (first opening 21 for air intake, second opening 22 on opposite side walls, and third opening 23 at the bottom for air exhaust) forms an orderly airflow path: the airflow carrying silver skin enters through the first opening 21, diffuses fully inside the silver skin box 20, and comes into full contact with the filters 24 at the second and third openings 22 and 23, maximizing the interception of silver skin. Compared with the problem of silver skin escape caused by the single opening in existing devices, this design makes it more difficult for silver skin in the airflow to get around the filter 24, significantly improving collection efficiency. In addition, the filter 24 is directly connected to the air exhaust opening, filtering the airflow at the source and preventing silver skin from entering other parts of the device and causing pollution, thus protecting the cleanliness of the internal equipment and reducing pollution to the operating environment. Overall, through structural optimization, the three core problems of "low collection efficiency", "inconvenient cleaning" and "equipment contamination" in existing technologies have been solved simultaneously, providing a basic and efficient solution for silver shavings collection.

[0027] This application constructs a complete silver skin collection logic through the collaborative design of the housing 10, the silver skin box 20, and the flip cover 30: the housing 10 provides the structural foundation and airflow inlet; the silver skin box 20 achieves efficient interception and convenient cleaning through its detachable design and multi-opening filter 24; and the flip cover 30 provides a convenient channel for placing and removing the silver skin box 20. The combination of these three elements structurally solves the problems of low silver skin collection efficiency, inconvenient cleaning, and chaotic airflow guidance in existing technologies, providing a basic and practical solution for silver skin collection.

[0028] Furthermore, the housing 10 also includes a sealing ring 31 disposed on the flip cover 30. When the flip cover 30 is in the state of closing the silver box placement cavity 11, the sealing ring 31 abuts against the opening edge of the silver box placement cavity 11.

[0029] When the flip cover 30 is closed, the sealing ring 31 abuts tightly against the edge of the placement cavity opening, completely eliminating the gap between them and preventing airflow carrying silver powder from leaking directly through the gap. This improvement brings multiple benefits: First, it prevents silver powder from drifting into the external environment with the leaking airflow, reducing pollution to the operating space and protecting the health of operators (avoiding the inhalation of silver powder); second, it ensures that all airflow must pass through the filter 24 inside the silver powder box 20 before being discharged, improving the silver powder interception rate and avoiding a decrease in collection efficiency due to air leakage; third, it reduces the possibility of silver powder entering other components of the device (such as the gaps inside the housing 10), reducing the risk of equipment failure caused by silver powder accumulation (such as component jamming and poor heat dissipation).

[0030] In addition, the sealing ring 31 made of silicone rubber or fluororubber (in conjunction with the following claims) has good elasticity and aging resistance, can maintain sealing performance for a long time, and is not prone to failure even in the high temperature environment of the baking process, ensuring long-term stable operation of the device.

[0031] Furthermore, the flip cover 30 is also provided with a locking assembly 40, which includes a switch handle 41, a sliding link 42, and a locking buckle 43. The edge of the housing 10 is recessed with a locking groove 14, and the flip cover 30 is provided with a sliding hole 32. The switch handle 41 is installed on the outer surface of the flip cover 30, and the locking buckle 43 is connected to the inner surface of the flip cover 30. The two ends of the sliding link 42 are respectively connected to the switch handle 41 and the locking buckle 43 and pass through the sliding hole 32. When the flip cover 30 closes the top of the silver box 20 placement cavity, the switch handle 41 is moved to drive the locking buckle 43 to be inserted into the locking groove 14.

[0032] The locking assembly 40 strengthens the connection between the flip cover 30 and the housing 10 through mechanical locking, and further enhances the sealing effect in conjunction with the sealing ring 31. Compared with designs that rely solely on the weight of the flip cover 30 or simple snap-fit, the locking assembly 40, through its linked snap-fit ​​structure, can apply a stable locking force, ensuring that the flip cover 30 does not loosen during device operation (such as airflow impact or equipment vibration), and preventing gaps from appearing between the sealing ring 31 and the edge of the placement cavity. When the flip cover 30 is closed and the locking mechanism is engaged, the sealing ring 31 can always remain in a tight contact state, preventing airflow carrying silver from escaping through gaps. This reduces pollution to the operating environment (preventing operators from inhaling silver) and ensures that all airflow must pass through the filter 24 inside the silver box 20, improving the silver interception rate.

[0033] The operating steps are as follows: When it is necessary to close the flip cover 30, rotate the flip cover 30 downwards so that it covers the top of the storage cavity of the silver box 20. At this time, the sealing ring 31 on the flip cover 30 initially contacts the edge of the opening of the storage cavity. Push (or pull) the switch handle 41 on the outside of the flip cover 30. The switch handle 41, through the sliding connecting rod 42 passing through the sliding hole 32, drives the locking buckle 43 on the inside of the flip cover 30 to move towards the edge of the box body 10. When the locking buckle 43 is inserted into the locking groove 14 at the edge of the box body 10, stop moving the switch handle 41. At this time, the flip cover 30 is firmly fixed, and the sealing ring 31 is tightly abutted against the edge of the storage cavity due to the pressure of the flip cover 30, achieving a complete seal. When it is necessary to unlock and open the flip cover 30, move the switch handle 41 in the opposite direction. The sliding connecting rod 42 drives the locking buckle 43 to disengage from the locking groove 14, and then the flip cover 30 can be rotated upwards to open the storage cavity of the silver box 20.

[0034] Based on the aforementioned latch assembly 40, a spring structure can be added between the locking buckle 43 and the inner surface of the flip cover 30. Specifically, one end of the spring is fixed to the inner side of the flip cover 30, and the other end is connected to the locking buckle 43. When the spring is in its natural state, the locking buckle 43 is positioned within the locking groove 14. Working principle: When the switch handle 41 is pushed, causing the locking buckle 43 to move away from the locking groove 14, the spring is compressed and stores elastic potential energy. When the locking buckle 43 is aligned with the locking groove 14, the switch handle 41 is released, and the spring releases its potential energy, pushing the locking buckle 43 to automatically spring into the locking groove 14, achieving rapid locking. The automatic reset function of the spring simplifies the unlocking operation, enabling rapid reset of the locking buckle 43 and the switch handle 41, thus improving operational convenience.

[0035] Furthermore, a filter device receiving cavity 13 is also provided inside the box 10 on one side of the silver box placement cavity 11. The filter device receiving cavity 13 is connected to the second opening 22 and the third opening 23 through the gap. After the primary filtration stage (filter 24 inside the silver powder box 20) intercepts most of the silver powder, the airflow carrying a small amount of fine silver powder enters the receiving chamber through the gaps. The receiving chamber can hold high-efficiency filtration components (such as HEPA filter 24, activated carbon filter, etc.) to specifically intercept the fine silver powder not removed by the primary filtration stage. The benefits of this design include: firstly, ensuring higher cleanliness of the final exhaust airflow, preventing fine silver powder from scattering into the air and causing pollution, thus protecting the operating environment and equipment; secondly, reducing the risk of fine silver powder entering other core components of the roaster (such as the fan and heating system), lowering the probability of equipment malfunctions due to silver powder accumulation (such as dust accumulation on fan blades affecting airflow, or silver powder covering the heating element causing overheating); and thirdly, providing users with flexible filtration upgrade options, allowing them to replace filters with different precision filters as needed, adapting to different roasting scenarios (such as using ordinary filters for home use and high-efficiency filters for commercial high-precision scenarios). In addition, the interconnected design of the accommodating cavity and the gap ensures that the airflow can smoothly enter the secondary filter, avoiding airflow turbulence caused by structural abruptness and ensuring the stability of filtration efficiency.

[0036] Furthermore, the filter 24 is a removable filter 24 that can be taken out of the silver case 20.

[0037] The removable filter 24 significantly improves the ease of maintenance and long-term stability of the device. Users can easily remove the filter 24 from the silver casing 20 for thorough cleaning (such as rinsing and wiping) or replacement, avoiding the "cleaning dead spots" (such as silver buildup at the connection between the filter 24 and the silver casing 20) caused by the fixed filter 24 in existing devices. This improvement brings multiple benefits: First, it maintains the permeability of the filter 24, ensuring smooth airflow and preventing a decrease in silver collection efficiency due to filter 24 blockage (such as silver not being effectively sucked into the silver casing 20 when airflow is obstructed); second, it extends the service life of the filter 24, and timely cleaning reduces corrosion of the filter 24 by silver (silver contains grease, which may oxidize and deteriorate over time), reducing the cost of frequent filter 24 replacements; third, it improves operational safety, allowing users to maintain the filter 24 without disassembling the entire silver casing 20 or touching the complex internal structure of the device, reducing the risk of accidental contact with components during operation (such as burns or component damage). In addition, the detachable design makes it convenient for users to regularly check the condition of the filter 24 (such as whether it is damaged or needs to be replaced), promptly identify and resolve filter 24 problems, and ensure that the device is always in optimal working condition.

[0038] Furthermore, the filter screen 24 is made of stainless steel.

[0039] The stainless steel filter 24 significantly enhances the durability and safety of the device. Stainless steel boasts excellent high-temperature resistance, capable of withstanding the high temperatures generated by airflow during roasting (typically 150-230℃), without deforming, aging, or releasing harmful substances due to high temperatures, ensuring the structural stability and safety of the filter 24. Simultaneously, the smooth and corrosion-resistant surface of stainless steel does not easily absorb coffee oils and silver residue, reducing clogging and deterioration of the filter 24 due to oil oxidation and extending its lifespan. Furthermore, the high strength of stainless steel makes it less susceptible to damage from airflow impact or wiping during cleaning, preventing the silver residue from directly penetrating the filter 24 if it breaks (if the filter 24 breaks, unfiltered silver residue will be discharged with the airflow, affecting collection efficiency). Compared to other materials (such as paper or ordinary plastic filters 24), the stainless steel filter 24 also offers the advantages of being repeatedly washable and environmentally friendly, reducing consumable costs and waste pollution from frequent filter replacements, making it more suitable for long-term use.

[0040] Furthermore, the housing 10 is made of metal or engineering plastic.

[0041] The choice of two materials provides flexibility for the device, meeting the needs of different usage scenarios. Metal materials (such as stainless steel and aluminum alloy) are characterized by high strength and high temperature resistance, making them suitable for commercial applications. Commercial coffee roasters have large roasting volumes and high usage frequency; the metal housing 10 can withstand long-term high-temperature environments and wear from frequent operation, while providing more stable support for internal components and reducing structural loosening due to vibration. Furthermore, the good thermal conductivity of metal helps dissipate heat transferred to the housing 10 during roasting, preventing overheating of the housing 10 from affecting surrounding components. Engineering plastics (such as ABS and PP) offer advantages such as light weight, low cost, and good moldability, making them more suitable for home use. Home coffee roasters are sensitive to equipment weight and cost; the plastic housing 10 reduces the overall weight of the equipment, facilitating movement and placement. At the same time, the good insulation properties of plastics reduce the risk of surface static electricity on the housing 10, improving safety for home use. In addition, engineering plastics can be injection molded into complex structures, facilitating the integration of more user-friendly designs (such as the latches on the flip cover 30 and the guide grooves in the placement cavity), enhancing the user experience. The choice of two materials allows the device to cover a wider range of market demands, enhancing the product's practicality and competitiveness.

[0042] Furthermore, the sealing ring 31 is made of silicone rubber or fluororubber.

[0043] The sealing ring 31, made of both silicone rubber and fluororubber, ensures the long-term reliability of the device's sealing performance. Silicone rubber possesses excellent elasticity and high-temperature resistance (withstanding a temperature range of -60℃ to 200℃), maintaining good deformation capacity in the high-temperature environment of roasting, ensuring a tight fit against the edge of the placement cavity and preventing loss of sealing effect due to high-temperature hardening. Simultaneously, silicone rubber has good aging resistance, maintaining its elasticity even after long-term use (such as thousands of opening and closing cycles of the lid 30), reducing the need for frequent replacement of the sealing ring 31. Fluororubber, on the other hand, has advantages in corrosion resistance and weather resistance, resisting the erosion of substances such as coffee bean oils and moisture in the air, preventing the sealing ring 31 from breaking due to chemical corrosion, making it suitable for commercial scenarios with long-term, high-frequency use. The choice of these two materials allows the sealing ring 31 to adapt to both the high-temperature environment of roasting and withstand the wear and corrosion of long-term use, ensuring the device's consistently stable sealing performance. This not only prevents the silver foil from escaping with leaking airflow but also reduces the risk of external dust and moisture entering the device, contaminating the silver foil, or affecting the filter components, making the overall performance of the device more reliable.

[0044] The present invention also proposes a coffee roaster 100, which includes a roasting assembly 1001 and a silver husk collection device 1 as described above. The roasting assembly 1001 is used to roast coffee beans and generate an airflow carrying coffee silver husks. The airflow outlet of the roasting bean assembly 1001 is connected to the inlet 12 of the shavings collection device 1, so as to transport the airflow carrying the coffee shavings from the roasting bean assembly 1001 to the shavings box 20 of the shavings collection device 1.

[0045] The specific structure of the silver skin collection device 1 is as described in the above embodiments. Since the coffee roaster 100 adopts all the technical solutions of all the above embodiments, it has at least all the beneficial effects brought about by the technical solutions of the above embodiments, which will not be described in detail here.

[0046] This design creates an "integrated scabbage handling solution" for the coffee roaster 100, significantly improving its practicality and safety. During roasting, the airflow carrying scabbage generated by the roasting component 1001 directly enters the scabbage collection device 1 through the airflow outlet, eliminating the need for additional piping or manual intervention. This achieves "real-time collection" of scabbage—avoiding the problem of scabbage spreading inside the roaster and requiring subsequent processing (e.g., scabbage adhering to the inner wall of the roasting chamber or fan blades). The benefits of this improvement include: firstly, improved cleanliness, reducing the frequency of internal cleaning by the user (traditional roasters require periodic disassembly to remove residual scabbage); secondly, reduced safety hazards caused by scabbage, preventing fire risks caused by scabbage accumulation near heating components (scabbage is flammable and easily ignites at high temperatures); and thirdly, ensured a stable roasting environment, as the timely collection of scabbage prevents it from drifting outside the roasting chamber and affecting the roasting quality of the coffee beans (e.g., scabbage falling into unroasted coffee beans and causing flavor contamination). In addition, the high-efficiency filtration function of the silver skin collection device 1 ensures that the airflow discharged from the roaster is clean, avoiding the environmental pollution caused by the silver skin in the exhaust of traditional roasters, making it more friendly for home or commercial baking scenarios.

[0047] Furthermore, the roasting bean assembly 1001 and the housing 10 of the shavings collection device 1 are integrated into the same casing, and the flip cover 30 of the shavings collection device 1 is disposed on the top or side surface of the casing.

[0048] The integrated design and optimized placement of the flip-top 30 make the coffee roaster 100 more suitable for practical use scenarios. Firstly, it saves space: the roasting component 1001 and the silver hull collection device 1 share a single casing, reducing redundant structures and connecting pipes in a separate design, making the device more compact and suitable for space-constrained environments such as home kitchens and small coffee shops. Secondly, it improves operational convenience: the flip-top 30 is located on the top or side surface of the casing, allowing users to open it without bending over or disassembling complex parts to access the silver hull collection box 20 for cleaning, making it particularly suitable for high-frequency commercial use. Thirdly, it enhances the overall integrity and aesthetics of the device: the integrated casing avoids exposed pipes and scattered components in a separate structure, making the device simpler and meeting the aesthetic needs of modern home and commercial environments. Fourthly, it improves structural stability: the integrated design reduces gaps between components, lowering the risk of loosening due to vibrations (such as fan vibrations during roaster operation) and extending the device's lifespan. In addition, the optimization of the flip cover's 30 position also takes ergonomics into account. The design of the top or side surface makes it easier for users to clean the silver cover, reducing operational fatigue and improving the user experience.

[0049] It is understood that the above embodiments only illustrate preferred embodiments of the present utility model, and their descriptions are relatively specific and detailed, but they should not be construed as limiting the scope of the present utility model patent. It should be noted that for those skilled in the art, the above technical features can be freely combined, and several modifications and improvements can be made without departing from the concept of the present utility model, all of which fall within the protection scope of the present utility model. Therefore, all equivalent transformations and modifications made within the scope of the claims of the present utility model should fall within the coverage of the claims of the present utility model.
