[0051] The door assembly and refrigeration device of the present application are described below with reference to Figures 1 to 6 . The door assembly of the present application can be applied to household appliances, such as refrigerators, but it should be understood that the door assembly of the present application can also be applied to dishwashers, washing machines, or any other suitable appliances. The refrigeration device of the present application is applied to a refrigerator, for example, but it should be understood that the refrigeration device of the present application can also be applied to freezers or any other suitable appliances.

[0052] In one embodiment of the present application, as shown in Figures 1 to 4, the door assembly is applied to a refrigeration device, which includes a housing 4, and the door assembly includes a door 2, a door panel 3, a traction mechanism 9, and a first sliding door mechanism 1. The door 2 is rotatably connected to the housing 4 of the refrigeration device and is suitable for opening or closing the storage space of the housing 4. A first mounting groove 21 is provided on the outer side of the door 2; the door panel 3 is slidably arranged on the outer side of the door 2; the first sliding door mechanism 1 is arranged in the first mounting groove 21, and the first end of the first sliding door mechanism 1 is transmission-connected to the housing 4 through the traction mechanism 9, and the second end of the first sliding door mechanism 1 is connected to the door panel 3. During the process of opening or closing the door 2, the traction mechanism 9 drives the first sliding door mechanism 1, so that the first sliding door mechanism 1 drives the door panel 3 to move relative to the width direction of the door 2.

[0053] In this embodiment, a first mounting slot 21 is designed on the outside of the door 2 to accommodate the first sliding door mechanism 1. This slot 21 provides a mounting location and space for the first sliding door mechanism 1. To ensure that the door panel 3 avoids obstacles such as walls and objects, it is slidably mounted on the outside of the door 2. A traction mechanism 9 primarily connects the housing 4 and the first sliding door mechanism 1, transmitting power and converting the movement of the housing 4 (e.g., opening or closing) into driving force for the first sliding door mechanism 1.

[0054] When the user rotates door 2, the traction mechanism 9, driven by the relative motion between door 2 and housing 4, drives the first sliding door mechanism 1 to perform corresponding movements. The first sliding door mechanism 1 is mounted in a first mounting slot 21 on the outside of door 2. The first end of the first sliding door mechanism 1 is drivingly connected to housing 4 via the traction mechanism 9, while the second end is connected to the door panel 3. Thus, when door 2 is opened or closed, the first sliding door mechanism 1 receives the driving force from the traction mechanism 9 and drives the door panel 3 to move relative to the width of door 2 to avoid obstacles such as walls and objects.

[0055] According to the door assembly of the embodiment of the present application, by positioning the first sliding door mechanism 1 in the first mounting slot 21 on the outside of the door 2, the first sliding door mechanism 1 can be concealed within the entire door assembly. One end of the first sliding door mechanism 1 is connected to the door body 4 via a traction mechanism 9, and the second end of the first sliding door mechanism 1 is connected to the door panel 3. As the door 2 is opened or closed, the first sliding door mechanism 1 drives the door panel 3 to move relative to the width of the door 2, allowing the door panel 3 to avoid obstacles such as walls and objects on the side.

[0056] In some embodiments, as shown in Figures 1 to 4, the first sliding door mechanism 1 is vertically arranged in the first mounting groove 21, and the first sliding door mechanism 1 includes: a first base 13, a first slider 11, a second slider 12, and a first connecting member. A first guide rail 131 is formed on the upper side of the first base 13, and a second guide rail 132 is formed on the lower side. The first slider 11 is slidably arranged on the first guide rail 131, and the first slider 11 is used to be connected to the box body 4 through the traction mechanism 9. The second slider 12 is slidably arranged on the second guide rail 132 and connected to the door panel 3. The two ends of the first connecting member are respectively connected to the first slider 11 and the second slider 12. When the first slider 11 moves on the first guide rail 131, the first slider 11 drives the second slider 12 to move in the opposite direction on the second guide rail 132 through the first connecting member, so as to drive the door panel 3 to move relative to the width direction of the box door 2.

[0057] Specifically, as shown in Figures 2 and 3, the first guide rail 131 is located on the upper side of the first base 13, providing a sliding track for the first slider 11. The second guide rail 132 is located on the lower side of the first base 13, parallel to or at a certain angle to the first guide rail 131, and provides a sliding track for the second slider 12. The first slider 11 is slidably mounted on the first guide rail 131 and is in driving connection with the housing 4. The second slider 12 is slidably mounted on the second guide rail 132 and is connected to the door panel 3. The first connector is connected to the first slider 11 and the second slider 12 at both ends.

[0058] When the door 2 is opened or closed, the relative movement between the box body 4 and the door 2 causes the first slider 11 to move on the first guide rail 131 under the driving force. Since the two ends of the first connecting member are respectively fixed to the first slider 11 and the second slider 12, by properly setting the extension direction of the first connecting member, the first connecting member will drive the second slider 12 to move in the opposite direction on the second guide rail 132. This synchronous reverse movement feature allows the door panel 3 to slide relative to the width direction of the box body 4.

[0059] The first sliding door mechanism 1 provided in the present application is configured by respectively arranging a first slider 11 and a second slider 12 on a first guide rail 131 and a second guide rail 132, and connecting the first slider 11 and the second slider 12 using a first connecting member, so that when the first slider 11 moves, it can drive the second slider 12 to move in the opposite direction. Therefore, when the first slider 11 is transmission-connected to the box body 4 and the second slider 12 is connected to the door panel 3, the first sliding door mechanism 1 can be used to drive the door panel 3 to slide relative to the width direction of the box door 2, thereby enabling the door panel 3 to avoid obstacles such as side walls and objects during the closing or opening process of the box door 2, so as to meet the user's usage needs in different scenarios.

[0060] It should be noted that, in practical applications, the designs of the first slider 11 and the second slider 12 can be flexible and varied to adapt to different working scenarios and performance requirements. They are not limited to specific shapes, sizes or materials, but can be customized and optimized according to specific needs.

[0061] From a material perspective, the first and second sliders 11 and 12 can be made of materials with high wear resistance, low friction coefficient, and good stability, such as metal alloys, engineering plastics, or special lubricating materials. These materials are selected to improve the durability of the sliders, reduce wear and noise during sliding, and ensure smooth sliding.

[0062] In terms of structural design, the first and second sliders 11 and 12 can utilize various guide rail contact surfaces, such as flat contact, ball contact, or sliding bearing contact. Each of these contact methods has its own advantages and disadvantages. For example, ball contact reduces friction and wear, but is more expensive; flat contact, on the other hand, offers a simpler structure but may require more frequent lubrication and maintenance. Therefore, the selection process should comprehensively consider factors such as usage conditions, cost-effectiveness, and ease of maintenance.

[0063] In addition, to enhance the load-bearing capacity and stability of the sliders, reinforcing ribs, support plates, or other auxiliary structures may be added to the first slider 11 and the second slider 12. These structures can increase the rigidity and deformation resistance of the sliders, ensuring stable sliding performance when bearing the weight of the door panel 3 and external forces.

[0064] In some embodiments, as shown in FIG5 , the first connector includes a first flexible cable and a second flexible cable, which can be ropes. The first flexible cable passes around the first end of the first base 13 , with both ends connected to the first ends of the first slider 11 and the second slider 12 , respectively. The second flexible cable passes around the second end of the first base 13 , with both ends connected to the second ends of the first slider 11 and the second slider 12 , respectively.

[0065] Specifically, the first end of the first flexible cable is fixed to a predetermined position on the first slider 11, then passes around a specific portion of the first base 13 (such as a pulley or guide device on the base), and finally connects to a corresponding position on the second slider 12. In this way, when the first slider 11 moves on the first guide rail 131, the first flexible cable can smoothly transmit this movement and drive the second slider 12 to move in the opposite direction on the second guide rail 132.

[0066] Similarly, the second cable also passes around the second end of the first base 13, but along a different path to ensure balance and stability between the two sliders. The first end of the second cable is fixed to another predetermined position on the first slider 11 (opposite the first cable connection point), then passes around the other side of the first base 13, ultimately connecting to the second end of the second slider 12. This dual-cable design not only enhances connection reliability but also ensures smoother and more stable operation of the entire first sliding door mechanism 1.

[0067] The performance of the sliding door mechanism can be further optimized by adjusting the paths and fixed points of the first and second flexible cables on the first base 13. For example, the tension of the first and second flexible cables can be adjusted to ensure synchronization and consistency of the movement of the first and second sliders 11 and 12.

[0068] In this embodiment, as shown in Figures 1 to 4, the first mounting groove 21 is located on the outside of the box door 2, and the first sliding door mechanism 1 is vertically arranged in the first mounting groove 21. Compared with the horizontal arrangement of the first sliding door mechanism 1, the depth of the first mounting groove 21 can be reduced to a certain extent, and the thickness of the box door 2 can be reduced. The first guide rail 131 and the second guide rail 132 are arranged parallel and side by side. This arrangement not only enhances the stability and load-bearing capacity of the first sliding door mechanism 1, but also makes the movement of the first slider 11 and the second slider 12 more stable and smooth. The first guide rail 131 faces the upper side. Such a design makes it easier for the first slider 11 on the first guide rail 131 to connect with the traction mechanism 9. The traction mechanism 9 is usually located near the top of the box body 4. The second guide rail 132 faces the lower side, opposite to the first guide rail 131, to cooperate with the connection of the door panel 3.

[0069] In some embodiments, a first ball and a first support member are provided between the first slider 11 and the first guide rail 131 and between the second slider 12 and the second guide rail 132. The first support member is provided with a first rolling notch, and the first ball is rollably arranged in the first rolling notch.

[0070] In this embodiment, a first support frame is set between the first slider 11 and the first guide rail 131, and a first support frame is set between the second slider 12 and the second guide rail 132 to limit the first ball therein, thereby preventing the first ball from shifting during rolling, and making the sliding of the first slider 11 and the second slider 12 more stable and reliable.

[0071] Specifically, the first rolling notch is an arc-shaped notch that matches the shape of the first ball. The arc-shaped notch improves the positioning effect of the first ball. Furthermore, when the first rolling notch contacts the first ball, the force is applied over a larger area, resulting in a more dispersed force. This can reduce wear between the first support frame and the first ball, thereby extending the service life.

[0072] In some embodiments, as shown in Figures 1 to 4, a second mounting groove 22 is provided on the outer side of the box door 2; the door body assembly also includes: a second sliding door mechanism 10 and a connecting rod 8; the second sliding door mechanism 10 is arranged in the second mounting groove 22, and the first end of the second sliding door mechanism 10 is connected to the first slider 11 through the connecting rod 8, and the second end of the second sliding door mechanism 10 is connected to the door panel 3. The second sliding door mechanism 10 is configured to cooperate with the first sliding door mechanism 1 to drive the door panel 3 to move relative to the width direction of the box door 2 during the process of opening or closing the box door 2.

[0073] Specifically, a second mounting groove 22 is provided on the outer side of the door 2, and the second mounting groove 22 provides installation space for the second sliding door mechanism 10. The main function of the second sliding door mechanism 10 is to cooperate with the first sliding door mechanism 1. During the process of opening or closing the door 2, the second sliding door mechanism 10 is also used to drive the door panel 3 to move relative to the width direction of the door 2. The connecting rod 8, as a component connecting the second sliding door mechanism 10 and the first slider 11, plays the role of transmitting force and motion. When the second sliding door mechanism 10 is driven by the first slider 11 on the first sliding door mechanism 1, the second sliding door mechanism 10 can cooperate to drive the door panel 3 to move. This design allows the door panel 3 to be further driven by the second sliding door mechanism 10 on the basis of being driven by the first sliding door mechanism 1, thereby increasing the driving force when the door panel 3 moves and increasing the stability of the door panel 3 when moving relative to the door 2.

[0074] In some embodiments, as shown in Figures 1 to 4, the second sliding door mechanism 10 is vertically disposed in the second mounting slot 22 and includes: a second base 101, a third slider 102, a fourth slider 103, and a second connecting member. A third guide rail 1011 is formed on the upper side of the second base 101, and a fourth guide rail 1012 is formed on the lower side. The third slider 102 is slidably disposed on the third guide rail 1011 and is connected to the first slider 11 via a connecting rod 8. The fourth slider 103 is slidably disposed on the fourth guide rail 1012 for connection to the door panel 3. The second connecting member is connected to the third slider 102 and the fourth slider 103 at both ends. During the opening or closing process of the door 2, the third slider 102 and the fourth slider 103 move in opposite directions to drive the door panel 3 to move relative to the width of the door 2.

[0075] In this embodiment, the second base 101 serves as the main body of the second sliding door mechanism 10, providing a stable mounting base and a sliding track. The second base 101 forms a third guide rail 1011 for the sliding of the third slider 102, and a fourth guide rail 1012 for the sliding of the fourth slider 103. The third slider 102 is slidably mounted on the third guide rail 1011 and is driven by the first slider 11 via the connecting rod 8. The fourth slider 103 is slidably mounted on the fourth guide rail 1012 and is connected to the door panel 3.

[0076] During the sliding process, the third slider 102 is driven by the connecting rod 8 to move linearly along the third guide rail 1011, thereby driving the fourth slider 103 to move, causing the door panel 3 to move accordingly. The connecting rod 8 connects the first slider 11 and the third slider 102, allowing the second sliding door mechanism 10 to receive the driving force from the first sliding door mechanism 1 and transmit this force to the door panel 3, driving it to move.

[0077] In this embodiment, as shown in Figures 2 to 5, the second mounting groove 22 is located on the outside of the door 2, and the second sliding door mechanism 10 is vertically disposed in the second mounting groove 22. The third guide rail 1011 is coaxially disposed with the first guide rail 131, and the third guide rail 1011 and the fourth guide rail 1012 are disposed parallel and side by side, so that when the first slider 11 moves on the first guide rail 131, the connecting rod 8 connects and drives the third slider 102 to move synchronously on the third guide rail 1011, thereby completing the adjustment of the positions of the first slider 11 and the third slider 102 through a single traction mechanism 9, so that the door panel 3 can move under the drive of the second slider 12 and the fourth slider 103.

[0078] To facilitate the placement of the first sliding door mechanism 1, the second sliding door mechanism 10 and the connecting rod 8, as shown in Figures 1 to 3, a third mounting groove 23 is provided in the box door 2, and the third mounting groove 23 is connected to the first mounting groove 21 and the second mounting groove 22. A part of the connecting rod 8 is movably arranged in the third mounting groove 23; the first end of the connecting rod 8 is located in the first mounting groove 21 and is connected to the second slider 12; the second end of the connecting rod 8 is located in the second mounting groove 22 and is connected to the third slider.

[0079] In actual applications, due to factors such as machine tool accuracy, tool wear, and material unevenness, there will be certain errors in the processing of the first guide rail 131, the second guide rail 132, the third guide rail 1011, the fourth guide rail 1012, the first base 13, and the second base 101. These errors may include dimensional errors (such as deviations in length, width, and height), shape errors (such as straightness, flatness, roundness, etc.), and position errors (such as coaxiality, parallelism, and perpendicularity). The parallelism between the first guide rail 131 and the second guide rail 132 is evaluated by measuring the relative position deviation between them. This deviation needs to be controlled within a certain tolerance range to ensure the smooth sliding of the corresponding slider and the stable operation of the system.

[0080] That is to say, in this embodiment, the direction of the guide rail setting, whether parallel or vertical, should not be strictly geometrical. At least the manufacturing and installation errors should be considered, and the error of plus or minus 10° should be understood as the scope of protection of the patent.

[0081] In one example, a second ball and a second support member are provided between the third slider 102 and the third guide rail 1011 and between the fourth slider 103 and the fourth guide rail 1012. The second support member is provided with a second rolling notch, and the second ball is rollably arranged in the second rolling notch.

[0082] In this embodiment, a second support frame is set between the third slider and the third guide rail 1011 and between the fourth slider 103 and the fourth guide rail 1012, and the second support frame is used to limit the second ball therein to prevent the second ball from shifting during rolling, so that the sliding of the third slider is more stable and reliable.

[0083] Typically, the second rolling notch is an arc-shaped notch that matches the shape of the second ball. This arc-shaped notch improves the positioning of the second ball. Furthermore, when the second rolling notch contacts the second ball, the force is applied over a larger area, resulting in a more dispersed force. This reduces wear between the second support frame and the second ball, extending its service life.

[0084] In this embodiment, the connecting rod 8 is a key component connecting the first and second sliding door mechanisms 1 and 10, and its placement is crucial. In this embodiment, a portion of the connecting rod 8 is movably positioned within the third mounting slot 23. This design allows the connecting rod 8 to flexibly adapt to changes in the relative positions of components within the first and second sliding door mechanisms 1 and 10 during movement, ensuring a stable and reliable connection. The first end of the connecting rod 8 is positioned within the first mounting slot 21 and tightly connected to the first slider 11 within the first sliding door mechanism 1. Therefore, when the first sliding door mechanism 1 is subjected to a driving force, this force is transmitted to the second sliding door mechanism 10 via the connecting rod 8. Simultaneously, the second end of the connecting rod 8 is positioned within the second mounting slot 22 and connected to the third slider 102 within the second sliding door mechanism 10. This allows the second sliding door mechanism 10 to receive the driving force from the first sliding door mechanism 1 and, in turn, drive the door panel 3 to move accordingly. The interconnected design of the third mounting slot 23, which houses the connecting rod 8, ensures a secure and smooth connection between the various components, enhancing the stability and reliability of the entire door assembly. Moreover, the provision of the third mounting groove 23 makes the layout of the first sliding door mechanism 1 , the second sliding door mechanism 10 , the connecting rod 8 and other components more reasonable and compact, thus saving space inside the door 2 .

[0085] In one embodiment of the present application, as shown in Figures 1 to 4 , the ends of the traction mechanism 9 are rotatably connected to the housing 4 and the first slider 11, respectively. Specifically, the traction mechanism 9 includes a traction rod, a first rotation axis mounting seat, and a second rotation axis mounting seat. The traction rod can be a linear guide rod or a curved guide rod, which can be adjusted according to specific needs. The first rotation axis mounting seat is connected to the first slider 11, and the second rotation axis mounting seat is used to connect to the housing 4. The first end of the traction rod is rotatably connected to the first rotation axis mounting seat, and the second end of the traction rod is rotatably connected to the second rotation axis mounting seat.

[0086] In this embodiment, by fixing the first rotating shaft fixing seat and the second rotating shaft fixing seat on the first slider 11 and the box body 4 respectively, and connecting the first rotating shaft fixing seat and the second rotating shaft fixing seat through a traction rod, when the box door 2 rotates relative to the box body 4, the angle between the box body 4 and the box door 2 changes, so that the first slider 11 is pulled through the transmission connection of the traction rod, the first rotating shaft fixing seat and the second rotating shaft fixing seat, so that the first slider 11 slides on the first base 13, and drives the second slider 12 to slide to realize the movement of the door panel 3 relative to the box door 2.

[0087] In some embodiments, as shown in FIG4 , a fourth mounting slot 24 is further provided on the outer side of the door panel 3, and the door assembly further includes a driven guide rail mechanism 14. The driven guide rail mechanism 14 is disposed in the fourth mounting slot 24 and is connected to the door panel 3. The driven guide rail mechanism 14 is configured to guide the movement of the door panel 3 relative to the width direction of the door 2 during the process of opening or closing the door 2.

[0088] Specifically, the fourth mounting slot 24 provides mounting space for the driven guide rail mechanism 14. The driven guide rail mechanism 14 primarily guides the door panel 3 in the widthwise direction of the door 2 during the opening or closing process of the door 2. This design allows the door panel 3, driven by the first and second sliding door mechanisms 1 and 10, to be further guided by the driven guide rail mechanism 14, thereby enhancing the smoothness of the movement of the door panel 3 relative to the door 2.

[0089] The driven guide rail mechanism 14 includes a third base and a fifth slider. A fifth guide rail is formed on the outer side of the third base; the fifth slider is slidably disposed on the fifth guide rail. In this embodiment, the fifth base serves as the main body of the driven guide rail mechanism 14, and the third base provides a stable mounting base and sliding track. The fifth guide rail formed by the fifth base is the sliding path of the fifth slider. The fifth slider is directly connected to the door panel 3. During the sliding process, the fifth slider will move linearly along the fifth guide rail, thereby driving the door panel 3 to move accordingly. Since the fifth slider is directly connected to the door panel 3, its sliding performance and stability will directly affect the movement effect of the door panel 3.

[0090] Based on the above embodiment, in some embodiments, one of the first mounting groove 21 and the fourth mounting groove 24 is arranged at the top of the outer side of the door 2 , and the other is arranged at the bottom of the outer side of the door 2 .

[0091] Typically, the first, second, and third mounting slots 21, 22, and 23 are all located at the top of the exterior of the door 2, accommodating the first and second sliding door mechanisms 1, 10, and connecting rod 8. The fourth mounting slot 24, located at the bottom of the exterior of the door 2, accommodates the driven guide rail mechanism 14. By simultaneously arranging the first and second sliding door mechanisms 1, 10, connecting rod 8, and driven guide rail mechanism 14, the upper portion of the door panel 3 is driven by the first and second sliding door mechanisms 10, while the lower portion of the door panel 3 is guided by the driven guide rail mechanism 14. This ensures stable operation of the door panel 3 as it slides widthwise relative to the door 2.

[0092] In another embodiment of the present application, as shown in Figures 1 to 6, a refrigeration device is provided, comprising: a housing 4 and a door assembly as provided in any of the above embodiments. The housing 4 is formed with a storage space, and the door 2 is rotatably connected to the housing 4, suitable for opening or closing the storage space. The door assembly is applied to a refrigeration device, comprising: a door 2, a door panel 3, a traction mechanism 9 and a first sliding door mechanism 1. The door 2 is rotatably connected to the housing 4, suitable for opening or closing the storage space of the housing 4. A first mounting groove 21 is provided on the outer side of the door 2; the door panel 3 is slidably arranged on the outer side of the door 2; the first sliding door mechanism 1 is arranged in the first mounting groove 21, the first end of the first sliding door mechanism 1 is transmission-connected to the housing 4 through the traction mechanism 9, and the second end of the first sliding door mechanism 1 is connected to the door panel 3. During the process of opening or closing the door 2, the traction mechanism 9 drives the first sliding door mechanism 1, so that the first sliding door mechanism 1 drives the door panel 3 to move relative to the width direction of the door 2.

[0093] Specifically, when the door 2 is rotated to open outside the housing 4, the first sliding door mechanism 1 drives the door panel 3 to slide away from the hinge 5, thereby preventing the door panel 3 from interfering with external obstacles. When the door 2 is rotated to close toward the housing 4, the first sliding door mechanism 1 drives the door panel 3 to slide toward the hinge 5, thereby preventing the door panel 3 from interfering with obstacles after closing.

[0094] In this embodiment, a door panel 3 is provided on the cabinet door 2. When the refrigeration device is embedded and arranged in a groove-shaped space, or when it is arranged between two cabinets, the door panel 3 can be arranged flush with the cabinets on the side walls or both sides of the groove to reduce the gap between the refrigeration device and the adjacent wall or cabinet, making it more beautiful.

[0095] In some embodiments, as shown in Figures 5 and 6, the door assembly and cabinet 4 are arranged within the installation space formed between the first cabinet 6 and the second cabinet 7. An opening is provided on the outside of the installation space. This design allows the door assembly and cabinet 4 to be integrally embedded within the cabinet. When the cabinet door 2 passes through the opening to control the opening or closing of the storage space, the first sliding door mechanism 1 is configured to drive the door panel 3 on the cabinet door 2 to move a predetermined distance away from or toward the hinge 5, so that the door panel 3 clears the side walls of the first cabinet 6 and the second cabinet 7.

[0096] When the door 2 passes through the opening to open or close the storage space, the first sliding door mechanism 1 is configured to drive the door panel 3 to move a predetermined distance on the door 2 in a direction away from or toward the hinge 5. To prevent the door panel 3 from interfering with the side walls of the first cabinet 6 and the second cabinet 7, the door panel 3 can be opened or closed smoothly through the predetermined movement without colliding or getting stuck with the cabinet side walls.

[0097] For example, as shown in Figures 5 and 6, when the door 2 is opened, the first sliding door mechanism 1 drives the door panel 3 to move a preset distance along the door 2 in a direction away from the hinge 5. In this way, the door panel 3 can smoothly avoid the side wall of the second cabinet 7, allowing the door 2 to be fully opened, making it convenient for the user to store and retrieve items.

[0098] Similarly, when the door 2 is closed, the first sliding door mechanism 1 drives the door panel 3 to move a preset distance along the door 2 toward the hinge 5. In this way, the door panel 3 can smoothly avoid the side wall of the first cabinet 6, allowing the door 2 to be completely closed, maintaining the overall aesthetics and sealing.

[0099] Finally, it should be noted that the above embodiments are intended only to illustrate the present application and are not intended to limit the present application. Although the present application has been described in detail with reference to the embodiments, those skilled in the art will appreciate that various combinations, modifications, or equivalent substitutions of the technical solutions of the present application do not depart from the spirit and scope of the technical solutions of the present application and are intended to be encompassed by the claims of the present application.
