Description

Technical Field

[0001] The present application relates to the field of daily maintenance of optical splitters, and in particular to a PLC optical splitter that is easy to maintain. Background Art

[0002] PLC optical splitter, full name Planar optical waveguide optical splitter, is an integrated waveguide optical power distribution device based on quartz substrate. It is mainly used in optical network systems to achieve coupling, branching and distribution of optical signals. This splitter connects the central office and terminal equipment in a passive optical network and realizes the branching of optical signals.

[0003] In the related art, the PLC optical splitter will continuously generate heat energy during use, which requires heat dissipation after long-term use to effectively ensure that the heat in the splitter is in a relatively stable state. When the optical splitter is dissipating heat, a heat dissipation port is often opened on the splitter, and the heat dissipation port is opened to allow the internal heat to dissipate. Although this traditional conventional heat dissipation method can achieve a certain heat dissipation effect, when the heat dissipation port is opened for heat dissipation, dust in the outside air can easily enter the splitter. Due to the precise structure of the optical splitter, once dust enters the PLC optical splitter, it is easy to affect its performance, such as increasing insertion loss and reducing the uniformity of light splitting. Therefore, how to ensure its stable heat dissipation while keeping the equipment clean is the key to ensuring its long-term stable operation. Summary of the invention

[0004] The present application provides a PLC optical splitter that is easy to maintain, the purpose of which is to optimize the heat dissipation process of the optical splitter so that it can effectively ensure the cleanliness of the equipment when the heat dissipation port is opened for heat dissipation without affecting the heat dissipation effect, thereby effectively preventing dust and other contaminants from invading the optical splitter, which is beneficial to extending the service life of the equipment.

[0005] The present application provides a PLC optical splitter that is easy to maintain, using the following technical solution: A PLC optical splitter that is easy to maintain, comprising a splitter body, the end of the splitter body is provided with a corresponding plug-in terminal for optical fiber insertion, a heat dissipation port is opened through the side end of the splitter body, and a heat dissipation component is added at the heat dissipation port; The heat dissipation assembly includes a driving member and a lifting plate, both of which are arranged to slide in the vertical direction, and the driving member and the lifting plate slide in the vertical direction in opposite directions. A movable plate is installed on the side of the driving member away from the splitter body for sliding in the vertical direction.

[0006] By adopting the above technical solution, when the splitter body does not need to dissipate heat, in this state, the driving part is located in the heat dissipation port to seal the heat dissipation port, and the lifting plate is located on the top of the driving part. When the splitter body needs to dissipate heat, the driving part rises and drives the lifting plate to descend. The lifting plate descends into the heat dissipation port and seals the heat dissipation port. At this time, the lifting plate divides the heat dissipation port into two independent left and right chambers. In this state, the heat accumulated in the splitter body enters the left chamber and is temporarily stored. At the same time, because the lifting plate is in a blocked state for the heat dissipation port at this time, the external dust and pollutants are blocked by the lifting plate outside the splitter body, thereby effectively preventing the external dust and pollutants from entering the splitter body and affecting its normal operation.

[0007] When the heat in the splitter body is temporarily stored, the driver descends, and the lifting plate begins to rise until the driver re-seals the heat dissipation port. In this state, the heat is temporarily stored in the heat dissipation port. At this time, the movable plate on the driver is opened upward, and the temporarily stored heat in the heat dissipation port is discharged from the movable plate to the outside of the splitter body.

[0008] This setting method can discharge the heat in the splitter body to the outside in time, and at the same time effectively prevent external dust and pollutants from entering the splitter body and affecting its normal operation through the driving part and the lifting plate, thereby optimizing the heat dissipation process of the optical splitter, so that it can effectively ensure the cleanliness of the equipment when the heat dissipation port is opened for heat dissipation without affecting the heat dissipation effect, thereby effectively preventing dust and other pollutants from invading the optical splitter, which is beneficial to extending the service life of the equipment.

[0009] Preferably, a driving assembly is provided between the driving member and the lifting plate, and the driving member drives the lifting plate to move up and down in a vertical direction through the driving assembly; The driving assembly includes a first wedge block, a second wedge block and a third wedge block, the first wedge block is integrally formed at the top of the driving member in the vertical direction, the second wedge block is horizontally arranged, and an end of the second wedge block close to the first wedge block and an end of the second wedge block close to the third wedge block are both wedge-shaped, the third wedge block is integrally formed at the top of the lifting plate in the vertical direction, an end of the first wedge block away from the driving member is wedge-matched with the second wedge block, an end of the third wedge block away from the lifting plate is wedge-matched with the second wedge block, and a paddle plate is integrally formed with the side of the driving member away from the splitter body in the horizontal direction.

[0010] By adopting the above technical solution, when the splitter body needs to dissipate heat, the driving member is moved upward through the shift plate. During the upward movement, the driving member simultaneously drives the first wedge block to rise. During the rising process, the first wedge block pushes the second wedge block to slide in the direction away from the first wedge block. During the sliding process, the second wedge block drives the third wedge block to move downward, and then drives the lifting plate to descend through the third wedge block until the lifting plate seals the heat dissipation port.

[0011] Preferably, a support plate for supporting the second wedge block is fixed on the side wall of the splitter body, a slide groove is provided at the bottom of the support plate along its length direction, a corresponding slider is integrally formed at the top of the second wedge block, and the slider is slidably installed in the slide groove, and a return spring is installed in the vertical direction between the top of the driving member and the lifting plate and the side wall of the splitter body.

[0012] By adopting the above technical solution, the support plate is used to stably support the second wedge block, and the slide groove and the slider are used to further enhance the stability of the second wedge block during the sliding process. The reset spring is used to assist the driving member and the lifting plate to reset.

[0013] Preferably, a first movable groove is formed on the side wall of the driving member in the vertical direction, the movable plate is slidably installed in the first movable groove, and a handle is integrally formed on the side wall of the movable plate.

[0014] By adopting the above technical solution, the first movable groove is used to provide space for the sliding of the movable plate, and the handle is used to facilitate the sliding of the movable plate downward.

[0015] Preferably, a water storage chamber is provided on the side wall of the splitter body, and the water storage chamber is used to store cooling water. A cooling channel is provided on the top of the splitter body, and the cooling channel and the water storage chamber are kept in communication. A pressure plate is provided in the water storage chamber along the horizontal direction, and the pressure plate is slidably arranged along the vertical direction. A first connecting rod is integrally formed with one end of the pressure plate along the vertical direction, and a second connecting rod is integrally formed between the bottom of the first connecting rod and the driving member, and the second connecting rod is arranged horizontally.

[0016] By adopting the above-mentioned technical solution, when the splitter body needs to dissipate heat, the driving member drives the first connecting rod to rise through the second connecting rod during the rising process, and the first connecting rod drives the pressure plate to rise while rising, so that the pressure plate can press the cooling water in the water storage chamber into the cooling channel. While the cooling water flows in the cooling channel, it further takes away the heat in the splitter body, which is beneficial to improve the heat dissipation effect of the splitter body.

[0017] Preferably, a sealing plate for sealing the cooling channel is provided on the top of the pressure plate in the vertical direction, a third connecting rod is integrally formed between the sealing plate and the pressure plate, and a second movable groove for the sealing plate to slide accordingly is provided on the inner wall of the top of the water storage chamber, and the sealing plate slides in the vertical direction in the second movable groove.

[0018] By adopting the above technical solution, when the splitter body does not need to dissipate heat, the sealing plate is blocked at the cooling channel, and the cooling water in the water storage chamber cannot enter the cooling channel in this state. When the splitter body needs to dissipate heat, the pressure plate moves up while pushing the sealing plate up in the second movable groove through the third connecting rod. At this time, the water inlet of the cooling channel gradually opens, and the cooling water is gradually pressed into the cooling channel during the pressure plate moving up.

[0019] Preferably, a guide plate is installed in the cooling channel at the top of the splitter body along its length direction, and the guide plate is arranged obliquely, and its side close to the water storage chamber is in a high position, and its side away from the water storage chamber is in a low position; Two driving gears are installed in the cooling channel of the side wall of the splitter body at intervals in the vertical direction, and two impellers are installed on the side of the splitter body away from the heat dissipation port. The two impellers are respectively connected to the two driving gears through corresponding rotating shafts.

[0020] By adopting the above technical solution, the guide plate is tilted, and the cooling water can flow more quickly and efficiently in the cooling channel after entering the cooling channel, thereby improving the heat dissipation efficiency.

[0021] After the cooling water enters the cooling channel on the side wall of the splitter, the cooling water drives the driving gear to rotate as it flows downward, and uses the driving gear to drive the corresponding impeller to rotate in the splitter body. During the rotation of the impeller, the heat in the splitter body can be effectively blown to the heat dissipation port for temporary storage, thereby further improving the heat dissipation effect of the splitter body. The side of the cooling channel away from the water storage chamber is open, and the cooling water is discharged to the outside of the splitter body through the side of the cooling channel away from the water storage chamber. When heat dissipation is not required, the side of the cooling channel away from the water storage chamber can be sealed by the corresponding plate.

[0022] Preferably, a guide groove is provided in the cooling channel of the side wall of the splitter body in a vertical direction, and the guide groove is located directly above one side of the driving gear.

[0023] By adopting the above technical solution, the guide groove is used to enable the cooling water to accurately and continuously act on the same side of the driving gear, thereby effectively ensuring the stability of the driving gear during rotation.

[0024] In summary, the present application includes at least one of the following beneficial technical effects: 1. When the splitter body does not need to dissipate heat, in this state, the driver is located in the heat dissipation port to seal the heat dissipation port, and the lifting plate is located on the top of the driver. When the splitter body needs to dissipate heat, the driver rises and drives the lifting plate to descend. The lifting plate descends into the heat dissipation port and seals the heat dissipation port. At this time, the lifting plate divides the heat dissipation port into two independent chambers on the left and right. In this state, the heat accumulated in the splitter body enters the chamber on the left and is temporarily stored. At the same time, because the lifting plate is in a blocked state for the heat dissipation port at this time, the external dust and pollutants are blocked by the lifting plate outside the splitter body, thereby effectively preventing external dust and pollutants from entering the splitter body and affecting its normal operation.

[0025] When the heat in the splitter body is temporarily stored, the driver descends, and the lifting plate begins to rise until the driver re-seals the heat dissipation port. In this state, the heat is temporarily stored in the heat dissipation port. At this time, the movable plate on the driver is opened upward, and the temporarily stored heat in the heat dissipation port is discharged from the movable plate to the outside of the splitter body.

[0026] This arrangement can discharge the heat in the splitter body to the outside in time, and at the same time effectively prevent external dust and pollutants from entering the splitter body and affecting its normal operation through the driving member and the lifting plate, thereby optimizing the heat dissipation process of the optical splitter, so that it can effectively ensure the cleanliness of the device when the heat dissipation port is opened for heat dissipation without affecting the heat dissipation effect, thereby effectively preventing dust and other pollutants from invading the optical splitter, which is conducive to extending the service life of the device; 2. When the splitter body needs to dissipate heat, the driving member drives the first connecting rod to rise through the second connecting rod during the rising process, and the first connecting rod drives the pressing plate to rise at the same time, so that the pressing plate can press the cooling water in the water storage chamber into the cooling channel. The cooling water further takes away the heat in the splitter body while flowing in the cooling channel, which is beneficial to improve the heat dissipation effect of the splitter body; 3. The guide plate is set at an angle so that the cooling water can flow more quickly and efficiently in the cooling channel after entering the cooling channel, thereby improving the heat dissipation efficiency.

[0027] After the cooling water enters the cooling channel on the side wall of the splitter, the cooling water drives the driving gear to rotate as it flows downward, and uses the driving gear to drive the corresponding impeller to rotate in the splitter body. During the rotation of the impeller, the heat in the splitter body can be effectively blown to the heat dissipation port for temporary storage, thereby further improving the heat dissipation effect of the splitter body. The side of the cooling channel away from the water storage chamber is open, and the cooling water is discharged to the outside of the splitter body through the side of the cooling channel away from the water storage chamber. When heat dissipation is not required, the side of the cooling channel away from the water storage chamber can be sealed by the corresponding plate. BRIEF DESCRIPTION OF THE DRAWINGS

DETAILED DESCRIPTION

[0030] The following is combined with Figure 1 -Attached Fig. 9 For further detailed description of this application.

[0031] Embodiment: The embodiment of this application discloses a PLC optical splitter that is convenient for maintenance. Refer to Figure 1 and Figure 2 , which includes a splitter body 1. Plug terminals 2 for fiber optic insertion are provided at the ends of the splitter body 1. A heat dissipation port 3 is formed through the side end of the splitter body 1, and a heat dissipation component 4 is added at the heat dissipation port 3. When the splitter body 1 does not need to dissipate heat, the heat dissipation port 3 is sealed by the heat dissipation component 4 to effectively ensure the stability of the fiber optic operation inside the splitter body 1. When the splitter body 1 needs to dissipate heat, the heat dissipation component 4 is used to open the heat dissipation port 3 for heat dissipation.

[0032] Refer to Figure 2 and Figure 3 , the heat dissipation component 4 includes a driving member 41 and a lifting plate 42. The driving member 41 and the lifting plate 42 are both slidably arranged in the vertical direction. The driving member 41 has an overall "U" - shaped structure, and the lifting plate 42 is in the shape of a rectangular parallelepiped plate. The lifting plate 42 is arranged on the top of the driving member 41, and the driving member 41 and the lifting plate 42 slide in the vertical direction in opposite directions: when the driving member 41 rises, it drives the lifting plate 42 to descend; when the driving member 41 descends, it drives the lifting plate 42 to rise.

[0033] Refer to Figure 2 , Figure 3 and Figure 4 , a movable plate 5 is slidably installed in the vertical direction on the side of the driving member 41 away from the splitter body 1. The movable plate 5 is in the shape of a rectangular parallelepiped.

[0034] When the splitter body 1 does not need to dissipate heat, in this state, the driving member 41 is located inside the heat dissipation port 3 to seal the heat dissipation port 3, and the lifting plate 42 is located on the top of the driving member 41. When the splitter body 1 needs to dissipate heat, the driving member 41 rises and drives the lifting plate 42 to descend. The lifting plate 42 descends into the heat dissipation port 3 and seals the heat dissipation port 3. At this time, the lifting plate 42 divides the heat dissipation port 3 into two independent chambers on the left and right. In this state, the heat accumulated inside the splitter body 1 enters the left chamber and is temporarily stored. At the same time, since the lifting plate 42 seals the heat dissipation port 3 at this time, dust and pollutants from the outside are blocked by the lifting plate 42 outside the splitter body 1, thereby effectively preventing dust and pollutants from the outside from entering the splitter body 1 and affecting its normal operation.

[0035] When the heat in the splitter body 1 is temporarily stored, the driving member 41 descends, and the lifting plate 42 begins to rise until the driving member 41 re-seals the heat dissipation port 3. In this state, the heat is temporarily stored in the heat dissipation port 3. At this time, the movable plate 5 on the driving member 41 is opened upward, and the temporarily stored heat in the heat dissipation port 3 is discharged from the movable plate 5 to the outside of the splitter body 1.

[0036] This arrangement can discharge the heat in the splitter body 1 to the outside in time, and at the same time effectively prevent external dust and pollutants from entering the splitter body 1 and affecting its normal operation through the driving member 41 and the lifting plate 42, thereby optimizing the heat dissipation process of the optical splitter, so that it can effectively ensure the cleanliness of the equipment when the heat dissipation port 3 is opened for heat dissipation without affecting the heat dissipation effect, thereby effectively preventing dust and other pollutants from invading the optical splitter, which is beneficial to extending the service life of the equipment.

[0037] A corresponding plate body for sealing the driving member 41 and the lifting plate 42 is installed on the outer side of the splitter body 1 to effectively ensure the integrity of the splitter body 1 .

[0038] Specifically, the position of the lifting plate 42 at the top of the driving member 41 is at the end of the driving member 41 away from the splitter body 1. This means that after the lifting plate 42 descends into the heat dissipation port 3, the chamber on the side close to the splitter body 1 is larger, while the chamber on the side away from the splitter body 1 is smaller, which is conducive to storing more heat.

[0039] Specifically, refer to Figure 2 , Figure 3 as well as Figure 4 A driving assembly 6 is provided between the driving member 41 and the lifting plate 42 , and the driving member 41 drives the lifting plate 42 to move up and down in the vertical direction through the driving assembly 6 .

[0040] Reference Figure 2 , Figure 3 as well as Figure 4 The driving assembly 6 includes a first wedge 61, a second wedge 62 and a third wedge 63. The first wedge 61 is integrally formed on the top of the driving member 41 in the vertical direction, and the second wedge 62 is arranged horizontally. The end of the second wedge 62 close to the first wedge 61 and the end of the second wedge 62 close to the third wedge 63 are both wedge-shaped. The third wedge 63 is integrally formed on the top of the lifting plate 42 in the vertical direction. The end of the first wedge 61 away from the driving member 41 is wedge-matched with the second wedge 62, and the end of the third wedge 63 away from the lifting plate 42 is wedge-matched with the second wedge 62.

[0041] Specifically, refer to Figure 2 , Figure 3 as well as Figure 4A shift plate 7 is integrally formed in the horizontal direction on one side of the driving member 41 away from the splitter body 1. When the splitter body 1 needs to dissipate heat, the driving member 41 is moved upward by the shift plate 7. During the upward movement, the driving member 41 simultaneously drives the first wedge block 61 to rise. During the upward movement, the first wedge block 61 pushes the second wedge block 62 to slide in a direction away from the first wedge block 61. During the sliding process, the second wedge block 62 drives the third wedge block 63 to move downward, and then drives the lifting plate 42 to descend through the third wedge block 63 until the lifting plate 42 seals the heat dissipation port 3.

[0042] Specifically, refer to Figure 2 , Figure 3 as well as Figure 4 A support plate 8 for supporting the second wedge block 62 is welded on the side wall of the splitter body 1. A slide groove is formed at the bottom of the support plate 8 along its length direction. A corresponding slider is integrally formed at the top of the second wedge block 62, and the slider is slidably installed in the slide groove. The support plate 8 is used to stably support the second wedge block 62, and the slide groove and the slider are used to further enhance the stability of the second wedge block 62 during the sliding process. At the same time, a reset spring 9 is installed between the top of the driving member 41 and the lifting plate 42 and the side wall of the splitter body 1 in the vertical direction, and the reset spring 9 is used to assist the driving member 41 and the lifting plate 42 in resetting.

[0043] Specifically, refer to Figure 4 and Figure 5 The side wall of the driving member 41 is provided with a first movable groove 10 in the vertical direction, and the movable plate 5 is slidably installed in the first movable groove 10, and the first movable groove 10 is used to provide space for the sliding of the movable plate 5. At the same time, the side wall of the movable plate 5 is integrally formed with a handle 11, and the handle 11 is used to facilitate the sliding of the movable plate 5 up and down.

[0044] Further, refer to Figure 2 and Figure 6 The side wall of the splitter body 1 is provided with a water storage chamber 12, and the water storage chamber 12 is used to store cooling water. At the same time, a cooling channel 13 is provided on the top of the splitter body 1, and the cooling channel 13 and the water storage chamber 12 are kept in communication. A pressing plate 14 is provided in the water storage chamber 12 along the horizontal direction, and the pressing plate 14 is slidably arranged along the vertical direction. A first connecting rod 15 is integrally formed at one end of the pressing plate 14 along the vertical direction, and a second connecting rod 16 is integrally formed between the bottom of the first connecting rod 15 and the driving member 41, and the second connecting rod 16 is arranged horizontally.

[0045] When the splitter body 1 needs to dissipate heat, the driving member 41 drives the first connecting rod 15 to rise through the second connecting rod 16 during the rising process. The first connecting rod 15 drives the pressure plate 14 to rise while rising, so that the pressure plate 14 can press the cooling water in the water storage chamber 12 into the cooling channel 13. When the cooling water flows in the cooling channel 13, it further takes away the heat in the splitter body 1, which is beneficial to improve the heat dissipation effect of the splitter body 1.

[0046] Specifically, refer to Figure 2 , Figure 6 as well as Figure 7 A sealing plate 17 for sealing the cooling channel 13 is provided on the top of the pressure plate 14 in the vertical direction, and a third connecting rod 18 is integrally formed between the sealing plate 17 and the pressure plate 14. A second movable groove 19 for the sealing plate 17 to slide correspondingly is provided on the inner wall of the top of the water storage chamber 12, and the sealing plate 17 slides in the second movable groove 19 in the vertical direction.

[0047] When the splitter body 1 does not need to dissipate heat, the sealing plate 17 blocks the cooling channel 13, and in this state, the cooling water in the water storage chamber 12 cannot enter the cooling channel 13. When the splitter body 1 needs to dissipate heat, the pressing plate 14 moves upward, and at the same time, the sealing plate 17 is pushed upward in the second movable groove 19 through the third connecting rod 18. At this time, the water inlet of the cooling channel 13 is gradually opened, and the cooling water is gradually pressed into the cooling channel 13 during the upward movement of the pressing plate 14.

[0048] Further, refer to Figure 2 and Figure 8 A guide plate 20 is installed in the cooling channel 13 at the top of the splitter body 1 along its length direction. The guide plate 20 is tilted, and the side close to the water storage chamber 12 is at a high position, and the side away from the water storage chamber 12 is at a low position. The guide plate 20 is tilted, and after the cooling water enters the cooling channel 13, it can flow more quickly and efficiently in the cooling channel 13, thereby improving the heat dissipation efficiency.

[0049] At the same time, two driving gears 21 are installed in the cooling channel 13 located on the side wall of the splitter body 1 at intervals in the vertical direction, and two impellers 22 are installed on the side of the splitter body 1 away from the heat dissipation port 3. The two impellers 22 are respectively connected to the two driving gears 21 through corresponding rotating shafts.

[0050] After the cooling water enters the cooling channel 13 on the side wall of the splitter, the cooling water drives the driving gear 21 to rotate during the downward flow, and uses the driving gear 21 to drive the corresponding impeller 22 to rotate in the splitter body 1. During the rotation process, the impeller 22 can effectively blow the heat in the splitter body 1 to the heat dissipation port 3 for temporary storage, thereby further improving the heat dissipation effect of the splitter body 1. The side of the cooling channel 13 away from the water storage chamber 12 is open, and the cooling water is discharged to the outside of the splitter body 1 through the side of the cooling channel 13 away from the water storage chamber 12. When heat dissipation is not required, the side of the cooling channel 13 away from the water storage chamber 12 can be sealed by the corresponding plate.

[0051] Specifically, refer to Figure 8 and Fig. 9 A guide groove 23 is vertically provided in the cooling channel 13 on the side wall of the splitter body 1, and the top of the guide groove 23 is located directly above one side of the driving gear 21. The guide groove 23 allows the cooling water to accurately and continuously act on the same side of the driving gear 21, thereby effectively ensuring the stability of the driving gear 21 during rotation.

[0052] The implementation principle of a PLC optical splitter that is easy to maintain in the embodiment of the present application is as follows: When the splitter body 1 does not need to dissipate heat, in this state, the driving member 41 is located in the heat dissipation port 3 to seal the heat dissipation port 3, and the lifting plate 42 is located on the top of the driving member 41. When the splitter body 1 needs to dissipate heat, the driving member 41 rises and drives the lifting plate 42 to descend. The lifting plate 42 descends into the heat dissipation port 3 and blocks the heat dissipation port 3. At this time, the lifting plate 42 divides the heat dissipation port 3 into two independent chambers on the left and right. In this state, the heat accumulated in the splitter body 1 enters the chamber on the left and is temporarily stored. At the same time, because the lifting plate 42 is in a blocking state for the heat dissipation port 3 at this time, the external dust and pollutants are blocked by the lifting plate 42 outside the splitter body 1, thereby effectively preventing the external dust and pollutants from entering the splitter body 1 and affecting its normal operation.

[0053] When the heat in the splitter body 1 is temporarily stored, the driving member 41 descends, and the lifting plate 42 begins to rise until the driving member 41 re-seals the heat dissipation port 3. In this state, the heat is temporarily stored in the heat dissipation port 3. At this time, the movable plate 5 on the driving member 41 is opened upward, and the temporarily stored heat in the heat dissipation port 3 is discharged from the movable plate 5 to the outside of the splitter body 1.

[0054] This arrangement can discharge the heat in the splitter body 1 to the outside in time, and at the same time effectively prevent external dust and pollutants from entering the splitter body 1 and affecting its normal operation through the driving member 41 and the lifting plate 42, thereby optimizing the heat dissipation process of the optical splitter, so that it can effectively ensure the cleanliness of the equipment when the heat dissipation port 3 is opened for heat dissipation without affecting the heat dissipation effect, thereby effectively preventing dust and other pollutants from invading the optical splitter, which is beneficial to extending the service life of the equipment.

[0055] The above are all preferred embodiments of the present application, and the protection scope of the present application is not limited thereto. Therefore, any equivalent changes made according to the structure, shape, and principle of the present application should be included in the protection scope of the present application.
