Description

Technical Field

[0001] This utility model belongs to the field of fan technology and relates to a desktop fan. Background Technology

[0002] In today's living and working environments, desktop fans, as a popular small appliance, provide an essential cool breeze for people on hot summer days or in stuffy environments. They can be seen everywhere, such as office desks, home studies, and bedside tables in bedrooms. However, traditional desktop fans often use a single rigid rod for support, making it difficult to balance concealed wiring with structural stability.

[0003] Existing desktop fans typically have power cords or control circuits fixed along the outer surface of the support structure or suspended directly between the base and the fan body. This wiring method not only affects the product's neat appearance but also poses risks such as the cable being easily pulled by external forces, loosening of the connectors, and even leakage. This is especially true for oscillating fan heads, where prolonged bending of the cable can easily damage the insulation layer. Furthermore, the support structure of existing desktop fans often uses a single, molded column or plate design, merely serving the basic function of supporting the fan body. This monotonous support form is not only aesthetically unappealing but also significantly limits functional expansion. While some products using concealed wiring achieve cable integration by increasing the cross-sectional size of the support rod, this results in a bulky product, contradicting the trend towards miniaturization of desktop devices.

[0004] Therefore, there is an urgent need in this field for a desktop fan to solve the above-mentioned technical problems. Utility Model Content

[0008] The support structure includes a first support member and a second support member. The first support member is connected between the base and the fan body. The second support member is connected to the first support member to jointly enclose a cable routing cavity for cable arrangement. The first support member is closer to the air outlet side of the fan body than the second support member, and the hardness of the first support member is greater than that of the second support member.

[0009] As a further improvement of this utility model, the first support member includes a connecting section, a first support section and a first bending section connected in sequence. The connecting section is connected to the fan body, the first bending section is connected to the base, and the first bending section is bent away from the air outlet side of the fan body.

[0010] As a further improvement of this utility model, the first support section is provided with a wiring port communicating with the wiring cavity near the connecting section, and the end of the wire passes through the wiring port and connects to the fan body.

[0011] As a further improvement of this utility model, the second support member includes a second support section and a second bent section connected to the second support section. The second support section is correspondingly connected to the first support section, and the second bent section is correspondingly connected to the first bent section. The second bent section is bent away from the air outlet side of the fan body.

[0012] As a further improvement of this utility model, the fan body includes a fan housing and a fan blade assembly. The fan housing has multiple air inlet holes located on the air inlet side. The connecting section is connected to the fan housing, and the fan blade assembly is installed inside the fan housing. The first support section has a first vent, and the second support section has a second vent corresponding to the first vent. In the direction from the air inlet side to the air outlet side, the projection of the first vent on the plane where the air inlet hole is located at least partially coincides with the air inlet hole.

[0013] As a further improvement of this utility model, the second support member further includes a connecting section, one side of which is connected to the edge of the second support section corresponding to the second vent, and the other side of which extends to fit against the edge of the first support section corresponding to the first vent.

[0014] As a further improvement of this utility model, the first support member is made of metal; and / or

[0015] The second support component is made of plastic or plastic.

[0016] As a further improvement of this utility model, the first support member is provided with a first mounting hole, the second support member is provided with a second mounting hole corresponding to the first mounting hole, and the support structure further includes a fixing member, which passes through one of the first mounting hole and the second mounting hole and is connected to the other of the first mounting hole and the second mounting hole, so as to position and connect the first support member to the second support member.

[0017] As a further improvement of this utility model, the number of the first mounting holes is multiple, and the multiple first mounting holes are divided into multiple mounting groups in groups of at least two. The multiple mounting groups include a first mounting group, a second mounting group and a third mounting group. The first mounting group is located at the end of the first support member near the fan body, the second mounting group is located at the end of the first support member near the base, and the third mounting group is located in the middle of the first support member.

[0018] As a further improvement of this utility model, the first mounting hole is a threaded hole, the second mounting hole is a through hole, and the fastener includes a screw, which passes through the through hole and is connected to the threaded hole to position and connect the first support member to the second support member.

[0021] The technical advantages of this utility model are as follows: Compared with the prior art, the desktop fan provided by this utility model completely encloses the cable within the support structure by setting a cable routing cavity, preventing exposed cables from being pulled or bent by external forces and aging, reducing the risk of leakage. It also isolates the cable from direct contact with the external environment, extending the cable's lifespan. Furthermore, the dual support components, the first and second, are designed to be separable, facilitating disassembly for individual replacement of damaged parts or repair of internal wiring, avoiding the high cost of replacing the entire support rod required in traditional integrated designs. By positioning the first support component near the fan body's air outlet side and using a high-hardness material, it can directly withstand the vibration generated by the airflow reaction force during fan operation, ensuring the support structure's rigidity and suppressing desktop fan wobbling. By using a lower-hardness material for the second support component, the overall weight of the desktop fan can be reduced while maintaining functionality, lowering production costs and achieving a balance between lightweight and high strength in the overall structure. This meets the performance requirements of the desktop fan while reducing production costs. Attached Figure Description

Detailed Implementation

[0031] To make the objectives, technical solutions, and advantages of this utility model clearer, the present utility model will be further described in detail below with reference to the accompanying drawings and specific embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the present utility model and are not intended to limit the scope of the present utility model.

[0032] In the description of this utility model, the terms "front", "rear", "top", "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 utility model 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 utility model.

[0033] Please refer to Figures 1-5 One embodiment of this utility model provides a desktop fan to solve the problem that the support structure of traditional desktop fans uses a single rigid rod, which makes it difficult to balance the concealment of wiring and structural stability.

[0034] Specifically, please refer to Figure 1 This is a perspective view of a desktop fan according to an embodiment of the present invention. The desktop fan 1 includes a base 10, a fan body 20, and a support structure 30. The base 10 provides a stable support surface, balancing the fan's operation through its own weight and friction with the placement surface, ensuring that the fan will not tip over when placed. The fan body 20 generates airflow, accelerating the air before blowing it out to create the cool breeze needed by people. The support structure 30 is located between the base 10 and the fan body 20, serving as a connection and support to ensure the overall stability of the desktop fan 1.

[0035] Please refer to Figures 2-3 The support structure 30 includes a first support member 31 and a second support member 32. The first support member 31 is connected between the base 10 and the fan body 20. Please refer to... Figure 4 The second support member 32 is connected to the first support member 31 to jointly enclose and form a cable routing cavity 33 for arranging the cables. The cable routing cavity 33 completely encloses the cables inside the support structure 30, preventing exposed cables from being pulled, bent, or aged by external forces, reducing the risk of leakage, and isolating the cables from direct contact with the external environment, thus extending the cable life. The dual support members 31 and 32 are designed to be separable, facilitating disassembly for individual replacement of damaged parts or repair of internal wiring, avoiding the high cost of replacing the entire traditional integrated support rod.

[0036] Specifically, the first support member 31 is closer to the air outlet side 212 of the fan body 20 than the second support member 32, and the hardness of the first support member 31 is greater than that of the second support member 32. The first support member 31, located near the air outlet side 212 of the fan body 20 and made of a high-hardness material, can directly withstand the vibrations generated by the airflow reaction force during the operation of the desktop fan 1, ensuring the support rigidity of the support structure 30 and suppressing the shaking of the desktop fan 1. The second support member 32, made of a lower-hardness material, can reduce the overall weight of the desktop fan 1 while maintaining functionality, thus lowering production costs. The high hardness of the first support member 31 absorbs high-frequency vibrations on the air outlet side 212, while the low hardness of the second support member 32 buffers low-frequency oscillations through slight deformation. The combination of these two components creates a complementary damping effect, improving overall stability. By selecting partitioned materials for the first support member 31 and the second support member 32, the first support member 31 is used to strengthen the rigidity in the stress area connected to the fan body 20, while the second support member 32 is used to reduce the weight in the non-critical area not connected to the fan body 20. This achieves a balance between lightweight and high strength in the overall structure, reducing production costs while meeting the performance requirements of the desktop fan 1.

[0037] As a further improvement to this utility model, please refer to Figures 5-7The first support member 31 includes a connecting section 311, a first support section 312, and a first bending section 313 connected in sequence. The fan housing 21 is located at the center of the air inlet side 211 and connected to the connecting section 311. The connection of the connecting section 311 to the center of the fan housing 21 avoids the obstruction of the airflow by the support structure, reduces local turbulence, and allows the airflow to enter the fan housing 21 evenly from the air inlet hole 2111, thereby improving the working efficiency of the fan blade assembly 22. In practical applications, the connection between the fan housing 21 and the connecting section 311 can be a rigid fixed connection or a quick-release interface connection. Specifically, the rigid fixed connection can be achieved by setting an internal thread at the center of the air inlet side 211 of the fan housing 21 and machining an external thread at the end of the connecting section 311, and then thread-locking the fan housing 21 and the connecting section 311. Alternatively, a boss can be set at the end of the connecting section 311, inserted into the slot at the center of the fan housing 21 for positioning, and then screwed through the fan housing 21 and the connecting section 311 for screwing, thereby strengthening the fixation. The quick-release interface connection can be achieved by setting a standard plug terminal at the end of the connecting section 311, which matches the socket set in the center of the fan housing 21, and quick assembly and disassembly are achieved through a snap-fit. The first bending section 313 is connected to the base 10. The segmented design attenuates vibration energy step by step. The connecting section 311 is directly connected to the fan body 20, ensuring a rigid connection between the fan body 20 and the support structure 30, reducing the transmission of high-frequency vibration. The first support section 312 provides bending stiffness and suppresses the back-and-forth swaying of the fan during operation. The first bending section 313 bends away from the air outlet side 212 of the fan body 20, forming an arc-shaped transition structure. This bending curvature disperses stress concentration between the base 10 and the support section, while simultaneously adjusting the fan's center of gravity to counteract the impact of the airflow reaction force on the stability of the base 10. The bending direction of the first bending section 313 is opposite to that of the air outlet side 212, creating a dynamic balance between the airflow reaction force generated by the fan body 20 and the deformation recovery force of the bending section. This reduces the risk of the base 10 tipping over, allowing it to more stably withstand the forces from the fan body 20. Even when the desktop fan 1 is running at high speed or subjected to external impact, it ensures the entire desktop fan 1 remains upright, reducing wobbling and displacement, and extending its lifespan. Furthermore, this bending design optimizes desktop space utilization to some extent, making the desktop fan 1 more compact when placed, thus improving the user experience.

[0038] As a further improvement of this utility model, the first support section 312 is provided with a cable routing port 3121 near the connecting section 311, which communicates with the cable routing cavity 33. The end of the cable passes through the cable routing port 3121 and connects to the fan body 20. Through the spatial positioning of the cable by the cable routing port 3121 and the communication design between the cable routing port 3121 and the cable routing cavity 33, a seamless transition connection of the cable from the cable routing cavity 33 to the fan body 20 is achieved. The setting of the cable routing port 3121 makes the cable routing inside the desktop fan 1 clearer and more orderly, avoiding the cable from wandering around inside the desktop fan 1. In the event of tangled or messy cable distribution, the cable is protected by the first support member 31 and the second support member 32 within the cable routing cavity 33, preventing excessive bending or compression of the cable, extending its service life, and reducing the probability of desktop fan 1 malfunctioning due to cable damage. At the same time, the cable is hidden within the cable routing cavity 33 and connected to the fan body 20 only through the cable routing port 3121, making the desktop fan 1 more concise and aesthetically pleasing, improving the overall appearance of the desktop fan 1, satisfying users' aesthetic needs for the appearance of the desktop fan 1, and increasing the competitiveness of the desktop fan 1 in the market.

[0039] As a further improvement of this utility model, the second support member 32 includes a second support segment 321 and a second bent segment 322 connected to the second support segment 321. The second support segment 321 is correspondingly connected to the first support segment 312, and the second bent segment 322 is correspondingly connected to the first bent segment 313. The second support member 32 forms a symmetrical and complementary structure with the first support member 31 through the segmented design of the second support segment 321 and the second bent segment 322, and the support function is enhanced through connection and cooperation. The second bent segment 322 bends away from the air outlet side 212 of the fan body 20. The second bent segment 322 is correspondingly connected to the first bent segment 313, and the second bent segment 322 also bends away from the air outlet side 212 of the fan body 20. The coordinated bending of the two bent segments greatly enhances the overall structural stability of the desktop fan 1. When the fan is running, the fan body 20 generates centrifugal force and torque due to wind direction adjustment, which are transmitted to the base 10 through the support structure 30. The first bending section 313 decomposes and transmits these forces, while the second bending section 322 further enhances the force dispersion effect by bending in conjunction with the first bending section 313. By working together with the first bending section 313, the complex forces are guided in a direction that is conducive to the stable support of the base 10, ensuring that the pressure on the base 10 is evenly distributed and maintaining the balance of the entire desktop fan 1.

[0040] The base 10 includes a seat body 11 and a battery assembly 12 housed inside the seat body 11. A first bending section 313 has a first connecting wall 3131 facing the seat body 11. The first connecting wall 3131 and the seat body 11 are fastened together to form a receiving cavity 13. The battery assembly 12 is housed inside the receiving cavity 13. A second bending section 322 has a second connecting wall 3221 at its end. The first connecting wall 3131 and the second connecting wall 3221 together form a cable outlet 3222. The end of the cable passes through the cable outlet 3222 and connects to the battery assembly 12. The design of section 2 makes the routing of the cable inside the base 10 clearer and more orderly, avoiding the cable from being randomly tangled or distributed inside the desktop fan 1. After the cable is led out from the battery assembly 12, it is hidden along the inside of the housing cavity 13, passes through the cable outlet 3222 and enters the cable routing cavity 33. The end of the cable passes through the cable routing port 3121 and connects to the fan body 20. The spatial positioning of the cable and the design of the cable hiding the cable through the cable outlet 3222, the cable routing cavity 33 and the cable routing port 3121 prevent the cable from being exposed and causing wear, while maintaining the neat appearance of the desktop fan 1.

[0041] As a further improvement of this utility model, the fan body 20 includes a fan housing 21 and a fan blade assembly 22. The fan housing 21 has multiple air inlets 2111 located on the air inlet side 211. A connecting section 311 is connected to the fan housing 21, and the fan blade assembly 22 is installed inside the fan housing 21. When the fan body 20 is running, the fan blade assembly 22 rotates, generating a negative pressure area inside the fan housing 21. Under the action of the pressure difference, outside air flows to the negative pressure area through the multiple air inlets 2111 on the air inlet side 211 to balance the air pressure. The first support section 312 has a first vent 3122, and the second support section 321 has a second vent 3211 corresponding to the first vent 3122. Along the direction from the air inlet side 211 to the air outlet side 212, the projection of the first vent 3122 on the plane where the air inlets 2111 are located at least partially coincides with the air inlets 2111. The first vent 3122 is located on the first support section 312, and the second vent 3211 is located on the second support section 321. The projection of both vents along the direction from the air inlet side 211 to the air outlet side 212 at least partially covers the air inlet hole 2111 of the fan housing 21, forming an axially connected auxiliary air duct. This ensures that the incoming airflow is not obstructed when it flows through the support structure 30, reduces turbulence, lowers airflow resistance, and reduces insufficient airflow caused by poor airflow or insufficient air intake, thus ensuring the stability of the output airflow of the desktop fan 1.

[0042] As a further improvement of this utility model, the second support member 32 also includes a connecting section 323. One side of the connecting section 323 is connected to the edge of the second support section 321 corresponding to the second ventilation opening 3211, and the other side of the connecting section 323 extends to fit against the edge of the first support section 312 corresponding to the first ventilation opening 3122. One side of the connecting section 323 connects to the edge of the second vent 3211 of the second support section 321, and the other side extends to the edge of the first vent 3122 of the first support section 312, forming a continuous and closed inner wall of the auxiliary air duct. This eliminates airflow leakage between the first vent 3122 and the second vent 3211, and reduces local eddies caused by airflow stripping. When the fan is running, air is drawn into the fan through the first vent 3122 and the second vent 3211. The tight fit between the connecting section 323 and the edges of the two vents guides the airflow more smoothly and concentratedly to the area where the fan blade assembly 22 is located, avoiding airflow leakage or turbulence caused by structural gaps. This allows as much air entering from the vents as possible to participate in the air circulation inside the desktop fan 1, improving air intake efficiency. At the same time, the connecting section 323 connects the first support member 31 and the second support member 32, greatly enhancing the integrity of the support structure 30, effectively preventing problems such as loosening or breakage of the support structure 30, extending the service life of the desktop fan 1, and improving the reliability of the desktop fan 1.

[0043] As a further improvement of this utility model, the first support member 31 is made of metal; and / or the second support member 32 is made of plastic. The first support member 31, made of metal, can stably withstand the vibrations caused by the motor rotation of the fan body 20, the centrifugal force caused by the fan blade rotation, and various forces such as external impacts that may be encountered during daily use, ensuring that the fan body 20 maintains a stable spatial position and will not easily shake, shift, or deform. The second support member 32, made of plastic, can be easily molded into a complex shape that closely matches the first support member 31 through injection molding and other processes, precisely enclosing and forming a wiring cavity 33 for storing the fan's power cord, signal cable, and other wires, ensuring neat and orderly wiring. Furthermore, during fan operation, the plastic second support member 32 can act as a buffer, absorbing some of the slight vibrations and impacts from the fan body 20 or external sources, assisting the first support member 31 in further stabilizing the overall fan structure. The first support component 31 is made of metal to ensure the strength requirements of the key support links. The second support component 32 is made of plastic to reduce weight and cost while meeting the auxiliary support function. The materials are selected according to the different functional requirements of different components, which avoids the waste of resources caused by uniformly using high-strength but heavy materials in traditional designs, or the problem of structural fragility caused by uniformly using lightweight materials.

[0044] As a further improvement of this utility model, the first support member 31 is provided with a first mounting hole 314, and the second support member 32 is provided with a second mounting hole 324 corresponding to the first mounting hole 314. The corresponding design of the first mounting hole 314 and the second mounting hole 324 realizes the precise assembly of the first support member 31 and the second support member 32 during connection. The support structure 30 also includes a fixing member 34, which passes through one of the first mounting hole 314 and the second mounting hole 324 and connects to the other of the first mounting hole 314 and the second mounting hole 324 to position and connect the first support member 31 to the second support member 32. The fixing member 34 connects the first support member 31 and the second support member 32 together by passing through and connecting the first mounting hole 314 and the second mounting hole 324, thereby realizing the positioning of the first support member 31 relative to the second support member 32. The engagement of the fastener 34 with the first mounting hole 314 and the second mounting hole 324 is similar to that of a bolt and nut. The fastener 34 can be specifically designed according to actual conditions and can be a screw, pin, or catch pin. The fastener 34 passes through one of the first mounting holes 314 and the second mounting hole 324 and connects to the other, forming a detachable structure. Friction or mechanical interlocking restricts the relative displacement of the support components, ensuring positioning stability. The engagement of the fastener 34 with the mounting holes provides a reliable connection between the first support component 31 and the second support component 32. This ensures that the fan will not loosen or separate during long-term operation and daily handling and use, effectively guaranteeing the stability of the support structure 30 and maintaining the overall normal operation of the desktop fan 1. Meanwhile, the standardized mounting hole and fastener 34 design makes the fan assembly process efficient and convenient. Workers on the production line only need to follow the established process to pass the fastener 34 through the corresponding mounting holes and tighten them in sequence to quickly complete the assembly of the support structure 30. Similarly, if the support structure 30 needs to be disassembled during after-sales maintenance, parts replacement or transportation, it can be easily operated, reducing production and maintenance costs and improving overall operational efficiency.

[0045] As a further improvement of this utility model, the number of first mounting holes 314 is multiple, and the multiple first mounting holes 314 are divided into multiple mounting groups of at least two. The multiple mounting groups include a first mounting group 3141, a second mounting group 3142, and a third mounting group 3143. The first mounting group 3141 is located at the end of the first support member 31 near the fan body 20, the second mounting group 3142 is located at the end of the first support member 31 near the base 10, and the third mounting group 3143 is located in the middle of the first support member 31. By setting the first mounting group 3141, the second mounting group 3142, and the third mounting group 3143 at the end of the first support member 31 near the fan body 20, the end of the first support member 31 near the base 10, and the middle of the first support member 31, respectively, the connection with the second support member 32 is strengthened in all directions from the connecting end of the fan body 20, the connecting end of the base 10 to the middle area. During assembly, the second mounting holes 324 on the second support member 32 correspond one-to-one with the first mounting holes 314. The fastener 34 passes through the corresponding mounting holes to fix the two. The first mounting group 3141 relieves the vibration and impact at the end of the fan body 20, the second mounting group 3142 balances the reaction force of the base 10, and the third mounting group 3143 counteracts the bending moment in the middle. This enables the support structure 30 to resist forces from all directions and of different types, making the entire support structure 30 more evenly stressed and reducing the risk of component damage caused by stress concentration. Whether it is the vibration and torsion when the fan is running at high speed, or the impact of external collisions and uneven placement surfaces, it can ensure that the desktop fan stands firmly, greatly extending the service life of the desktop fan 1.

[0046] As a further improvement of this utility model, the first mounting hole 314 is a threaded hole, and the second mounting hole 324 is a through hole. The fixing member 34 includes a screw, which passes through the through hole and connects to the threaded hole to position the first support member 31 on the second support member 32. When the first mounting hole 314 is a threaded hole and the second mounting hole 324 is a through hole, the screw passes through the second mounting hole 324 and is screwed into the first mounting hole 314. When the screw is screwed into the threaded hole, the threads mesh with each other, preventing the screw from loosening, thereby tightly connecting the first support member 31 and the second support member 32 together. In some embodiments, the second mounting hole 324 is a threaded hole, and the first mounting hole 314 is designed as a through hole. After the screw passes through the through hole of the first support member 31, it is screwed into the threaded hole of the second support member 32. The friction between the threads and the pressing force of the screw head on the surface of the first support member 31 are used to tightly fix the first support member 31 and the second support member 32 together. The friction between the threads and the clamping force of the screw head provide a strong connection, ensuring that the first support 31 and the second support 32 are firmly connected together. Even under conditions of long-term fan operation with vibration or minor external impacts, this connection will not easily loosen, ensuring the stability and reliability of the fan support structure 30. Furthermore, the screw connection method offers good repeatability, ensuring consistent quality and strength of the connection during repeated disassembly and installation of the support components in product testing or improvement processes.

[0047] Of course, in other embodiments, the fixing member 34 may also include a pin. In this case, the first mounting hole 314 is a first insertion hole, and the second mounting hole 324 is a second insertion hole corresponding to the first insertion hole. The pin is inserted into the two corresponding first and second insertion holes, restricting the relative movement of the first support member 31 and the second support member 32 in the direction perpendicular to the pin, thereby achieving positioning. At the same time, the pin may be designed with protrusions or grooves, and corresponding structural fits are provided in the first and / or second insertion holes to prevent the pin from rotating in the first and second insertion holes. This accurately defines the relative position of the first support member 31 and the second support member 32. Meanwhile, the pin connection method causes less damage to the first support member 31 and the second support member 32. In cases where multiple disassemblies and reassemblies are required, it is beneficial to protect the structural integrity of the first support member 31 and the second support member 32. Furthermore, the quick-plug design of the pin and insertion hole fits together, which can also improve the maintainability and flexibility of the first support member 31 and the second support member 32.

[0048] In some other embodiments, the fastener 34 may also include a locking pin. In this case, the first mounting hole 314 is a first locking hole, and the second mounting hole 324 is a second locking hole corresponding to the first locking hole. The locking pin has a certain elastic deformation capability. When the locking pin is inserted into the first and second locking holes, it undergoes elastic deformation and enters the first and second locking holes, then returns to its original shape and is locked in the first and second locking holes, preventing the relative movement of the first support member 31 and the second support member 32, thereby achieving accurate positioning of the first support member 31 relative to the second support member 32. The cooperation between the locking pin and the locking hole can provide good positioning accuracy and can withstand a certain amount of vibration and impact loads. Furthermore, the locking pin and the locking hole are easy to assemble and disassemble. When disassembly is required, only a certain external force needs to be applied to deform the locking pin and remove it from the first and second locking holes. At the same time, the size of the locking pin and the locking hole is small, which will not occupy too much space and will help reduce the overall volume of the first support member 31 and the second support member 32.

[0049] The technical features of the above embodiments can be combined in any way. For the sake of brevity, not all possible combinations of the technical features in the above embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.

[0050] The above embodiments only illustrate preferred implementations of this utility model, and their descriptions are relatively specific and detailed, but they should not be construed as limiting the scope of the patent application. 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.
