Description

Technical Field

[0001] This utility model relates to the field of household appliance technology, and in particular to a buckle and clothing processing device. Background Technology

[0002] Clothes dryers are used to dry clothes. During use, the internal heat exchanger system typically requires routine cleaning. To facilitate this cleaning, dryer casings usually have a maintenance opening and a maintenance door for opening and closing. The maintenance door needs to be opened for cleaning and closed afterward. Currently, a magnetic hinge mechanism is commonly used to mount the maintenance door to the casing. While this method is relatively convenient for opening and closing, the magnetic and hinge mechanisms usually require secondary assembly, making the installation process complex and costly. Utility Model Content

[0003] At least one technical problem solved by this utility model is that the installation steps of existing maintenance doors are complicated and costly.

[0004] To solve the above-mentioned technical problems, this utility model provides a buckle, including: a connecting arm; a cantilever, one end of which is connected to the connecting arm, the extension direction of the cantilever intersects the engagement direction of the buckle, and the dimension of the cantilever in its own extension direction is greater than the dimension of the connecting arm in the engagement direction; and a snap-fit ​​portion, which is disposed at the other end of the cantilever away from the connecting arm.

[0005] Compared with the prior art, the technical solution of this utility model embodiment has the following beneficial effects:

[0006] Because the extension direction of the cantilever intersects with the engagement direction, the limitation of the engagement direction on the cantilever length is reduced, helping the cantilever to provide sufficient length in its extension direction to meet the elastic deformation requirements when the buckle engages. This type of buckle provides a connection option in scenarios where the engagement direction space is relatively limited. When used to connect objects, the buckle installation steps are simple, usually requiring only one installation, and the cost is low. Furthermore, this type of buckle not only achieves the anti-detachment function but also improves the ease of assembly and disassembly.

[0007] Optionally, the extension direction of the cantilever is perpendicular to the engagement direction. This minimizes the spatial constraints on the cantilever length imposed by the engagement direction, further enhancing the flexibility in designing the cantilever's length along its own extension direction.

[0008] Optionally, the ratio of the dimension of the cantilever in its extension direction to the engagement amount of the snap-fit ​​portion is greater than or equal to 5. This ensures that the cantilever can provide relatively suitable elastic deformation, allowing the snap-fit ​​to be installed and removed with appropriate force. This is especially useful in scenarios where frequent disassembly and installation are required, as it not only prevents the snap-fit ​​from coming off but also improves the ease of disassembly and installation.

[0009] Optionally, a transition section is provided at the junction of the connecting arm and the cantilever. This transition section improves the connection strength between the connecting arm and the cantilever, disperses stress at the junction during use, prevents breakage of the connecting arm and cantilever at the junction due to repeated elastic deformation of the cantilever, and extends the service life of the buckle.

[0010] Optionally, the transition section is arc-shaped. This can improve the stress dispersion effect of the transition section at the joint, further reducing the probability of the connecting arm and cantilever breaking at the joint due to multiple elastic deformations of the cantilever.

[0011] Optionally, the extension direction of the cantilever and the engagement direction define an extension plane. In a direction perpendicular to the extension plane, the engagement portion protrudes from the surface of the cantilever to provide a corresponding engagement space, which facilitates engagement.

[0012] Optionally, the buckle also includes reinforcing ribs on the connecting arm. Since the deformation of the buckle during disassembly and installation is mainly concentrated on the cantilever, and the connecting arm primarily serves to connect and fix the cantilever to a designated object, such as a maintenance door, the deformation of the cantilever during engagement will affect the connecting arm. By providing reinforcing ribs on the connecting arm, the strength of the connecting arm can be improved, preventing deformation and breakage, and extending the service life of the buckle.

[0013] Optionally, along the engagement direction, the engaging portion includes an inlet portion and an outlet portion to facilitate the installation and removal of the buckle.

[0014] Optionally, the connecting arm has a cantilever on at least one side perpendicular to the engagement direction of the buckle.

[0015] This application also provides a garment processing device, including: a housing having a maintenance opening thereon; a maintenance door for opening or closing the maintenance opening; the garment processing device further includes: any of the above-mentioned latches, the latches being disposed on the maintenance door, the housing having a latching portion, the latching portion cooperating with the latched portion to form a latching connection, wherein the connecting arm is connected to the maintenance door.

[0016] Since the extension direction of the cantilever intersects with the engagement direction, the space limitation on the cantilever length in the engagement direction (the direction between the maintenance door and the housing) can be reduced. This helps the cantilever to provide sufficient length in its extension direction to meet the elastic deformation requirements when the buckle engages, thus realizing the connection between the maintenance door and the housing through the buckle. Since the buckle is low in cost and the installation steps are simple, it can reduce the cost and assembly steps of the garment handling equipment. While achieving the anti-detachment function, it can also improve the ease of disassembly and assembly.

[0017] Optionally, the housing includes a metal panel, the metal panel at least partially forming the maintenance opening and having the snap-fit ​​portion; or the housing includes a metal panel and a plastic part adjacent to the metal panel, the plastic part at least partially forming the maintenance opening and having the snap-fit ​​portion.

[0018] Optionally, the latching portion is an edge or slot provided on the housing, the connecting arm is provided on the inner side of the maintenance door, the distance from the inner side of the maintenance door to the edge or slot is less than the distance from the end of the cantilever connected to the connecting arm to the latching portion in the extension direction of the cantilever, and the distance from the inner side of the maintenance door to the edge or slot is less than the dimension of the connecting arm in the engagement direction.

[0019] Optionally, when the snap-fit ​​portion is located on the plastic part, the metal panel has a covering portion overlapping the plastic part, and the plastic part is located inside the metal panel. The covering portion has a clearance opening, which corresponds to the position of the snap-fit ​​portion on the plastic part. The clearance opening is used to expose the snap-fit ​​portion. When modifying some existing garment processing equipment to use a snap-fit ​​connection for maintenance doors, if the metal panel has a covering portion overlapping the plastic part, it is only necessary to provide a clearance opening on the covering portion to expose the snap-fit ​​portion. This eliminates the need to modify the existing product mold, reducing the modification cost of the garment processing equipment.

[0020] Optionally, the garment handling device is a drying device and includes a heat exchanger disposed at the bottom of the drying device, the plastic part is a box housing the heat exchanger, the maintenance opening corresponds to the heat exchanger and is formed on the metal panel and / or the plastic part, the metal panel is a front panel facing the user, and the maintenance door is disposed on the lower side of the front panel.

[0021] Optionally, one end of the maintenance door is pivotally connected to the housing, and the other end is engaged with the housing via a buckle. Along an extension axis parallel to the pivot axis, there are multiple buckles arranged sequentially. The connecting arms of the two outermost buckles face opposite directions to the engaging portion, thereby improving the firmness of fixing the edge of the maintenance door.

[0031] To make the above-mentioned objectives, features and beneficial effects of the present invention more apparent and understandable, the specific embodiments of the present invention will be described in detail below with reference to the accompanying drawings.

[0032] This application provides a snap fastener, see [link]. Figure 1 The buckle 10 includes a connecting arm 11, a cantilever 12, and a locking portion 13. One end of the cantilever 12 is connected to the connecting arm 11. The extension direction x of the cantilever 12 intersects the engagement direction y of the buckle 10, and the dimension L2 of the cantilever 12 in its extension direction x is greater than the dimension L3 of the connecting arm 11 in the engagement direction y. The locking portion 13 is located at the other end of the cantilever 12 away from the connecting arm 11.

[0033] The dimension L2 of the cantilever 12 in its own extension direction x is the length of the cantilever 12 in its own extension direction x, that is, the dimension L2 of the cantilever 12 in its own extension direction x is the length from the end of the cantilever 12 connected to the connecting arm 11 to the end of the locking part 13 away from the connecting arm 11. The dimension L3 of the connecting arm 11 in the engagement direction y is the length of the connecting arm 11 in the engagement direction y.

[0034] As can be seen from the above scheme, since the extension direction x of the cantilever 12 intersects the engagement direction y, the limitation of the engagement direction y on the length of the cantilever 12 can be reduced. This helps the cantilever 12 to provide sufficient length in its extension direction x to meet the elastic deformation requirements when the buckle engages. The buckle 10 provides the possibility of buckle connection in scenarios where the engagement direction space is relatively limited. When the buckle 10 is used to connect objects, the installation steps of the buckle 10 are simple, usually requiring only one installation, and the cost is low. In addition, using this type of buckle 10 can improve the ease of disassembly and assembly while achieving the anti-detachment function.

[0035] In some embodiments, the extension direction x of the cantilever 12 is perpendicular to the engagement direction y. Figure 1 The following is an example illustrating the situation where the extension direction x of the cantilever 12 is perpendicular to the engagement direction y. In this way, the extension direction x of the cantilever 12 is relatively independent of the engagement direction y, which can minimize the limitation of the space in the engagement direction y on the length of the cantilever 12 in its own extension direction x, allowing the cantilever 12 to be flexibly and freely configured with sufficient length to meet the elastic deformation requirements when the buckle engages.

[0036] When it is necessary to release the latch 10, apply a force to the latch 10 in the opposite direction to the engagement direction y to pull the latch 10.

[0037] It is understandable that the angle between the extension direction x and the engagement direction y of the cantilever 12 is configured based on the available space in the engagement direction y in the actual use scenario.

[0038] For ease of description, Figure 1In the illustrated embodiment, the surface of the cantilever 12 with the latching portion 13 is referred to as the upper surface. The extension direction x of the cantilever 12 and the engagement direction y define an extension plane 15. During the engagement process of the latch 10, the cantilever 12 will be subjected to a force z perpendicular to the extension plane 15. Under the action of this force z, the cantilever 12 deforms downward. Since the engagement direction y intersects with the extension direction x of the cantilever 12, due to the presence of the connecting arm 11, while resisting the downward deformation of the cantilever 12, the free end of the connecting arm 11 away from the root will also be driven downward by the cantilever 12. Under the combined action of the connecting arm 11 and the cantilever 12, a torsional force is generated. Since the torsional force is not only a downward component, but also includes the component force at the root of the connecting arm 11 and the connection point between the cantilever 12 and the connecting arm 11, it resists the deformation of the cantilever 12 when it is repeatedly disassembled, making it easy for the cantilever 12 to recover after deformation. Under the action of torsional force, even if the buckle 10 is repeatedly disassembled and reassembled, it is not easy for the buckle 10 to disengage due to failure, thus extending the service life of the buckle 10. Among them, the root of the connecting arm 11 refers to the end that is connected to the installation object (such as a maintenance door), and the free end of the connecting arm 11 is the end that is opposite to the root in the engagement direction y, and is not connected to other structures.

[0039] In specific implementation, the ratio of the dimension of the cantilever 12 in its own extension direction x to the engagement amount of the locking part 13 is greater than or equal to 5. The engagement amount is the vertical distance between the highest point of the locking part 13 and the engagement point. In this way, it can be ensured that the cantilever 12 can provide relatively suitable elastic deformation, so that the buckle 10 can be installed and removed with appropriate force. Especially in scenarios where disassembly and installation are frequently required, it improves the convenience of disassembly and installation while achieving the anti-loosening effect.

[0040] In a specific implementation, a transition portion 14 is provided at the connection between the connecting arm 11 and the cantilever 12. The transition portion 14 can improve the connection strength between the connecting arm 11 and the cantilever 12, disperse the stress at the connection during the use of the buckle 10, avoid the connecting arm 11 and the cantilever 12 from breaking at the connection due to repeated elastic deformation of the cantilever 12, and extend the service life of the buckle 10.

[0041] In some embodiments, the transition portion 14 is arc-shaped. This improves the stress dispersion effect of the transition portion 14 at the joint, further reducing the probability of the connecting arm 11 and the cantilever 12 breaking at the joint due to multiple elastic deformations of the cantilever 12.

[0042] In some embodiments, the extension direction x of the cantilever 12 and the engagement direction y define an extension plane 15, and the engagement portion 13 protrudes from the surface of the cantilever 12 in a direction perpendicular to the extension plane 15. The engagement portion 13 may protrude from either the upper or lower surface of the cantilever 12. By configuring the engagement portion 13 to protrude from the surface of the cantilever 12, a corresponding engagement space can be provided, facilitating engagement.

[0043] The buckle 10 also includes reinforcing ribs 16 disposed on the connecting arm 11. During the disassembly and installation of the buckle 10, the deformation area of ​​the buckle 10 is mainly concentrated on the cantilever 12. The connecting arm 11 primarily serves to connect and fix the cantilever 12 to a designated object, such as the maintenance door 30. During the engagement process, the cantilever 12 will be subjected to a force z perpendicular to the extension plane 15. Under the action of this force z, the cantilever 12 deforms, which will have a certain impact on the connecting arm 11. By providing reinforcing ribs 16 on the connecting arm 11, the strength of the connecting arm 11 can be improved, preventing deformation and breakage of the connecting arm 11 and extending the service life of the buckle 10.

[0044] In some embodiments, the reinforcing rib 16 extends parallel to the engagement direction y. This allows the free end of the connecting arm 11 to have a certain degree of elasticity while also providing corresponding support force to the cantilever 12 in the engagement direction y, helping the cantilever 12 to recover after deformation and delaying the occurrence of buckle failure caused by multiple deformations of the cantilever 12.

[0045] In a specific implementation, along the engagement direction y, the engaging portion 13 includes an inlet portion 131 and an outlet portion 132. During engagement, the inlet portion 131 guides the object engaging with the buckle 10 (such as the engaged portion) to smoothly pass the highest point of the engaging portion 13 and lock into a certain position on the outlet portion 132. During disengagement, the outlet portion 132 guides the object engaging with the buckle 10 to move towards the inlet portion 131 and smoothly pass the highest point of the engaging portion 13, thereby disengaging from the engaging portion 13.

[0046] In some embodiments, both the inlet portion 131 and the outlet portion 132 are inclined surfaces. The angle of the inclined surfaces of the inlet portion 131 and the outlet portion 132 can be configured according to the disassembly and assembly force requirements of the latch 10.

[0047] Furthermore, the snap-fit ​​portion 13 may include a hollow structure to reduce the weight of the snap-fit ​​portion 13 and reduce the deformation of the other end of the cantilever 12 caused by the weight of the snap-fit ​​portion 13.

[0048] The connecting arm 11 has the cantilever 12 on at least one side perpendicular to the engagement direction y of the buckle 10.

[0049] In this embodiment, the accompanying drawings illustrate an example where the connecting arm 11 has a cantilever 12 on one side perpendicular to the engagement direction y of the buckle 10. In practice, a cantilever 12 can also be provided on the other side. When the connecting arm 11 has cantilever 12 on both sides perpendicular to the engagement direction y of the buckle 10, the connecting arm 11 and the cantilever 12 on both sides form a "T" shape. In one scenario, the cantilever 12 on both sides can be symmetrical relative to the connecting arm 11.

[0050] See Figures 1 to 9 This application also provides a garment processing device 100, which includes a housing 20, a maintenance door 30, and a latch 10. The housing 20 has a maintenance opening 201. The maintenance door 30 is used to open or close the maintenance opening 201. The latch 10 is disposed on the maintenance door 30, and the housing 20 has a latching portion 204. The latching portion 13 cooperates with the latching portion 204 to form a latching connection, wherein the connecting arm 11 is connected to the maintenance door 30.

[0051] Due to space constraints in the garment processing equipment 100, and the fact that the maintenance door 30 is typically flush with the outer surface of the housing 20 (such as the front panel) to maintain the overall integrity of the garment processing equipment 100, the space between the maintenance door 30 and the housing 20 is limited. Existing conventional latches have the same engagement direction as the cantilever extension direction. When the maintenance door opens and closes, it moves along the engagement direction y, perpendicular to the plane of the cantilever. With use, the latch is prone to deformation and disengagement. Furthermore, in the engagement direction, the space between the maintenance door 30 and the housing 20 does not meet the cantilever length design of the latch, and cannot satisfy the elastic deformation requirements during latch engagement. Therefore, existing conventional latches cannot be used for the installation of the maintenance door.

[0052] The buckle 10 provided in the above embodiments of this application, since the extension direction x of the cantilever 12 intersects the engagement direction y, can reduce the limitation of the space in the engagement direction y (the direction between the maintenance door 30 and the housing 20) on the length of the cantilever 12. This helps the cantilever 12 to provide sufficient length in its extension direction x to meet the elastic deformation requirements when the buckle engages, thus realizing the connection between the maintenance door 30 and the housing 20 through the buckle 10. Since the buckle 10 has low cost and simple installation steps, it can reduce the cost and assembly steps of the clothing handling equipment 100. In addition to achieving the anti-detachment function and preventing the maintenance door 30 from falling off during the operation of the clothing handling equipment 100, it can also improve the convenience of disassembly and assembly.

[0053] In specific implementations, the specific structural form of the latching part 204 varies depending on the specific structure of the housing 20. Examples are given below.

[0054] In some embodiments, see Figure 6 and Figure 7 The housing 20 includes a metal panel 202, which at least partially forms the maintenance opening 201 and is provided with the snap-fit ​​portion 204.

[0055] In other embodiments, see Figure 8 The housing 20 includes a metal panel 202 and a plastic part 203 adjacent to the metal panel 202. The plastic part 203 at least partially forms the maintenance opening 201 and is provided with a snap-fit ​​portion 204.

[0056] In a non-limiting embodiment, the plastic part 203 may have a flange 2031, and the snap-fit ​​portion 204 may be formed on the flange 2031. The figure illustrates an example where the flange 2031 extends vertically; in practice, the flange 2031 may also extend horizontally or in other directions, depending on the position of the maintenance door 30 on the housing 20 and the direction of the pivot axis connecting it to the housing 20.

[0057] Combination Figure 4 , Figure 7 and Figure 8 The latching part 204 is an edge or groove provided on the housing 20. The connecting arm 11 is provided on the inner side 304 of the maintenance door 30. The distance L1 between the inner side 304 of the maintenance door 30 and the edge or groove is less than the distance L4 from the end of the cantilever 12 connected to the connecting arm 11 to the latching part 13 in the extension direction of the cantilever 12. Furthermore, the distance L1 between the inner side 304 of the maintenance door 30 and the edge or groove is also less than the dimension L3 of the connecting arm 11 in the engagement direction y.

[0058] The distance between the inner side 304 of the maintenance door 30 and the edge or slot is: the distance between the inner side 304 of the maintenance door 30 and the edge or slot when the maintenance opening 201 of the maintenance door 30 is closed.

[0059] In some embodiments, when the snap-fit ​​portion 204 is disposed on the plastic part 203, the metal panel 202 has a shielding portion 2021 overlapping the plastic part 203, and the plastic part 203 is disposed on the inner side of the metal panel 202. The shielding portion 2021 is provided with a clearance opening 2022, the clearance opening 2022 corresponding to the position of the snap-fit ​​portion 204 on the plastic part 203. The clearance opening 2022 is provided to expose the snap-fit ​​portion 204. When modifying some existing garment processing equipment 100 to use a snap-fit ​​10 to connect the maintenance door 30, for the metal panel 202 having a shielding portion 2021 overlapping the plastic part 203, it is only necessary to provide a clearance opening 2022 on the shielding portion 2021 to expose the snap-fit ​​portion 204. This eliminates the need to modify the existing product mold, resulting in lower modification costs for the garment processing equipment 100.

[0060] Combination Figure 1 and Figure 8 The following description uses the example of the locking part 13 being located on the upper surface of the cantilever 12. When the maintenance door 30 is closed, the user pushes the maintenance door 30 toward the housing 20. The maintenance door 30 is subjected to at least a component force along the engagement direction y. As the maintenance door 30 continues to move toward the housing 20, the locking part 13 will contact the locked part 204. Subsequently, the locked part 204 presses the locking part 13 downward. Under the pressure of the locked part 204, the locking part 13 retracts downward, and the cantilever 12 deforms downward at this point. The engaged portion 204 moves along the guide portion 131 of the engaged portion 13. After passing the highest point of the engaged portion 13, the compression on the engaged portion 13 decreases, that is, the downward force on the cantilever 12 decreases. The cantilever 12 moves upward to restore its deformation. When the maintenance door 30 is pushed into place, the engaged portion 204 engages with the corresponding position of the guide portion 132 to restrict the maintenance door 30 from moving away from the housing 20, that is, to restrict the buckle 10 from disengaging in the opposite direction of the engagement direction y. When the engaged portion 204 engages with the guide portion 132, in the direction perpendicular to the extension plane 15 (vertical direction in this embodiment), the engaged portion 204 and the engaged portion 13 overlap to restrict the engaged portion 13 from moving in the opposite direction of the engagement direction y.

[0061] When the user opens the maintenance door 30, by pulling the maintenance door 30 away from the housing 20, that is, pulling the maintenance door 30 in the opposite direction of the engagement direction y, the engaged part 204 moves along the outlet part 132 toward the inlet part 131. At this time, the engaged part 204 presses the outlet part 132 downward, causing the cantilever 12 to move downward and undergo elastic deformation. When the engaged part 204 passes the outlet part 132 and the highest point of the engaging part 13, the engagement between the engaging part 13 and the engaged part 204 is released, and the engagement of the latch 10 is released. At this time, the compressive force of the engaged part 204 on the engaging part 13 decreases, and the cantilever 12 moves upward to restore its deformation.

[0062] In some embodiments, the metal panel 202 has a bent portion 2023 that bends toward the interior of the housing 20. The bent portion 2023 forms a recessed space toward the interior of the housing 20, and the maintenance door 30 is located within the recessed space formed by the bent portion 2023. This helps to achieve flushness between the maintenance door 30 and the outer surface of the housing 20 and to cover some components inside the housing 20, thereby improving the overall integrity of the garment handling device 100.

[0063] The aforementioned shielding portion 2021 may be part of the bending portion 2023.

[0064] It should be noted that in some scenarios, the metal panel 202 may not have a shielding portion 2021 that overlaps with the plastic part 203. In this case, the metal panel 202 will not shield the snap-fit ​​portion 204 on the plastic part 203.

[0065] The garment processing device 100 is a drying device and includes a heat exchanger disposed at the bottom of the drying device. The plastic part 203 is a box housing the heat exchanger. The maintenance opening 201 corresponds to the heat exchanger and is formed on the metal panel 202 and / or the plastic part 203. The metal panel 202 is a front panel facing the user. The maintenance door 30 is disposed on the lower side of the front panel.

[0066] In some embodiments, the housing 20 is provided with ventilation holes 303 for heat dissipation of the heat exchanger.

[0067] In some embodiments, one end 301 of the maintenance door 30 is pivotally connected to the housing 20, and the other end 302 is engaged with the housing 20 via a latch 10. Along an extension axis P parallel to the pivot axis, there are multiple latches 10 arranged sequentially. The connecting arms 11 of the two outermost latches 10 have opposite directions to the engaging portion 12, thereby improving the firmness of the fixation to the edge of the maintenance door 30. Figure 2 and Figure 3The illustration uses four latches 10, which are located on the top of the maintenance door 30 and pivot at the bottom of the maintenance door 30 and the housing 20. In practice, the number of latches 10 can be other than that of the maintenance door 30. The latches 10 can also be located on the side of the maintenance door 30 or other areas. This is not limited here.

[0068] That is, the cantilever 12 of the two outermost buckles 10 is located on different sides of the connecting arm 11 on the engagement direction y perpendicular to the buckle 10.

[0069] Furthermore, the cantilever 12 of the two outermost latches 10 is located on the outside of the connecting arm 11 in the engagement direction y perpendicular to the latches 10. Specifically, the connecting arm 11 on the outside of the engagement direction y refers to the side edge of the maintenance door 30 that is perpendicular to the extension axis P of the pivot axis.

[0070] When the user opens the maintenance door 30, by pulling the other end 302 of the maintenance door 30 away from the housing 20, that is, pulling the other end of the maintenance door 30 in the opposite direction of the engagement direction y, the latch 10 can be released, and the connection between the other end 302 of the maintenance door 30 and the housing 20 is released. Continuing to pull the maintenance door 30 will cause it to rotate around the pivot axis. Figure 2 The bold black solid arrow in the middle indicates the direction of movement of the other end 302 when maintenance door 30 is opened. Figure 7 The bold black solid arrow in the middle indicates the direction of movement of the other end 302 when maintenance door 30 is closed.

[0071] In one embodiment, when the maintenance door 30 is rotated a certain angle around the pivot axis, the maintenance door 30 can be removed from the housing 20 to fully expose the maintenance opening 201, which facilitates the cleaning of lint inside the heat exchanger.

[0072] The extension axis P of the pivot axis can be the length direction of the maintenance door 30, the width direction, or other suitable directions. The attached diagram illustrates this by showing the extension axis P of the pivot axis as the length direction of the maintenance door 30, extending horizontally. In practice, when the maintenance door 30 is closed, the extension axis P of the pivot axis can also be vertical, or other directions perpendicular to the vertical direction; these will not be illustrated here.

[0073] Although specific embodiments have been described above, these embodiments are not intended to limit the scope of this utility model disclosure, even when only a single embodiment is described with respect to a particular feature. The feature examples provided in this utility model disclosure are intended to be illustrative and not limiting, unless otherwise stated. In practice, one or more technical features of the dependent claims may be combined with the technical features of the independent claims as needed and where technically feasible, and the technical features from the respective independent claims may be combined in any suitable manner rather than solely by the specific combinations listed in the claims.

[0074] While the present invention has been disclosed above, it is not limited thereto. Any person skilled in the art can make various modifications and alterations without departing from the spirit and scope of the present invention; therefore, the scope of protection of the present invention should be determined by the scope defined in the claims.
