Description

Technical Field

[0001] The present application relates to the technical field of drying equipment, and in particular to a drying device for producing heat sinks. Background Art

[0002] As a key device for converting AC power into DC power, the stability and reliability of the rectifier's operation are crucial. In the production process of the rectifier, the heat sink usually needs to go through multiple processing steps, such as cutting, forming, surface treatment, etc. After these processes are completed, some moisture often adheres to the surface of the heat sink, which will interfere with the combination of the coating and the surface of the heat sink, causing defects such as shedding and blistering of the coating, thereby affecting the protective performance and insulation performance of the coating. Therefore, before spraying the heat sink, the heat sink needs to be placed in a tunnel furnace for drying, and then the subsequent dried heat sink is sprayed.

[0003] For example, a Chinese patent document with publication number CN216347606U discloses a high-efficiency tunnel drying furnace for panel manufacturing, including a main body mounting frame, wherein the main body mounting frame is internally movably installed with evenly distributed transmission shafts, and the external fixed sleeve of the transmission shaft is provided with a driving wheel, one end of the transmission shaft is fixedly installed with a synchronous pulley located outside the main body mounting frame, and the external movably sleeve of the synchronous pulley is provided with a transmission synchronous belt, a driving motor is fixedly installed on the side of the main body mounting frame away from the synchronous pulley, and the output shaft of the driving motor is fixedly connected to any transmission shaft, an upper drying box is fixedly installed on the top of the main body mounting frame, and a lower drying box is fixedly installed on the bottom of the main body mounting frame, and heating mechanisms are provided inside the upper drying box and the lower drying box. Heating mechanisms are arranged at the top and bottom of the main mounting frame, and the panel is suspended by placing a driving wheel. The driving motor drives the synchronous pulley, the transmission synchronous belt and the transmission shaft, and the driving wheel is rotated to drive the panel to move inside the main mounting frame, so that both sides of the panel are dried at the same time through the heating mechanisms on the upper and lower sides.

[0004] In the above-mentioned related technologies, both sides of the panel are dried by the heating mechanisms on the upper and lower sides. However, during the drying process, the panel needs to be placed on a conveyor belt with holes, and the panel is sent into the drying box through the conveyor belt. Due to the existence of the conveyor belt, the heating mechanism arranged below needs to be arranged below the conveyor belt. At this time, due to the obstruction of the transmission belt, part of the heat emitted by the heating mechanism below will be blocked by the conveyor belt, and then the drying time needs to be increased to dry the workpiece, thereby causing the drying efficiency of the workpiece to decrease. Summary of the invention

[0005] The present application provides a drying device for heat sink production, aiming to solve the problem of low heat sink drying efficiency in the related art.

[0006] The present application provides a drying device for heat sink production using the following technical solution: A drying device for producing heat sinks, comprising a drying box and a conveyor belt arranged in the drying box, the drying box being provided with a swinging assembly for driving the heat sink to swing in the drying box along a direction perpendicular to the rotation direction of the conveyor belt, the swinging assembly comprising a mounting frame fixed to the drying box, a swinging shaft rotatably connected to the mounting frame and a swinging frame fixed to the swinging shaft, the swinging frame being used for providing limited support for the heat sink moving in the drying box, at least two swinging assemblies being provided, the heat sink being provided between two adjacent swinging assemblies, and the heat sink between the two swinging frames being driven to swing during the swinging of the two adjacent swinging frames, and a control assembly for driving the swinging frames to swing back and forth at intervals being provided in the drying box.

[0007] By adopting the above technical scheme, when drying the heat sink, the staff will place the heat sink between two adjacent swing frames in sequence and at intervals, so that the heat sink remains in an inclined state, and the inclined heat sink abuts against one of the swing frames, and then under the action of the conveyor belt, the heat sink between the adjacent swing frames is driven to move in the drying box along the direction of rotation of the conveyor belt. During the movement, the heat sink on the conveyor belt can be dried by the drying box, and then while moving, the two adjacent swing frames can be driven by the control component to swing back and forth at intervals in the drying box along the width direction of the conveyor belt. During the swinging of the heat sink, the originally relatively static air will form an airflow due to the swinging of the heat sink, and then the flow of air in the drying box will be accelerated. When the air flow is accelerated, the drying speed of the heat sink can be increased, thereby reducing the drying time of the heat sink, and then achieving the purpose of saving electricity.

[0008] Optionally, the control assembly includes a control rod slidably connected to the drying box body, a connecting rod fixed on the swing frame, a rotating block rotatably connected to the control rod, and a control cylinder for driving the control rod to move along the width direction of the conveyor belt, the rotating block is slidably connected to the connecting rod, and multiple control rods, connecting rods and rotating blocks are provided, and the multiple control rods, connecting rods and rotating blocks correspond one-to-one to the multiple swing frames.

[0009] By adopting the above technical solution, when the control cylinder drives the control rod to move back and forth along the width direction of the conveyor belt, the connecting block will rotate on the control rod, and at the same time the connecting block will slide on the connecting rod, thereby driving the connecting rod and the swing frame fixed on the connecting rod to swing back and forth around the swing axis, thereby achieving the purpose of facilitating the swing frame and the heat sink arranged between the swing frames to swing.

[0010] Optionally, the swing frame is provided with a conveying assembly for conveying the heat sinks between the swing frames, the conveying assembly includes two conveying rollers rotatably connected to the swing frame and a conveyor belt wound around the two conveying rollers, the surface of the conveyor belt abuts against the heat sink, and the swing frame is provided with a conveying motor for driving one of the conveying rollers to rotate.

[0011] By adopting the above technical solution, during the rotation of the conveyor belt, the heat sink between two adjacent swing frames is driven to move, and at the same time, the conveying motor drives the conveying roller to rotate, and the rotation of the conveying roller drives the conveyor belt to rotate, so that the rotation speed of the conveyor belt is the same as the rotation speed of the conveyor belt, and then the friction between the heat sink and the swing frame can be reduced, thereby achieving a better effect when conveying the heat sink.

[0012] Optionally, the drying box is provided with a rotating component for further drying the heat sink removed from the drying box; the rotating component includes a rotating disk rotatably connected to the side of the drying box and a plurality of placement plates fixed on the fixed disk, the placement plates are provided with placement grooves for placing the heat sinks, the heat sink removed from the drying box is moved into the placement grooves, and the rotation of the rotating disk drives the placement plates and the heat sinks arranged in the placement grooves to rotate.

[0013] By adopting the above technical solution, after the heat sink is removed from the drying box, a small amount of moisture will still appear in some of the heat sinks. At this time, the heat sink itself still has a certain temperature, and a very long conveyor belt needs to be set up. The heat sink is transported on the conveyor belt, and the moisture in the heat sink will evaporate within a certain period of time. At the same time, after the heat sink becomes cool, it is convenient for the staff to collect and pack it. At this time, the heat sink removed from the drying box enters the placement slot, and then the rotating disk rotates, driving the heat sink in the placement slot to rotate, which will accelerate the evaporation of moisture on the surface of the heat sink, thereby making the heat sink drying effect better.

[0014] Optionally, the conveyor belt is evenly provided with a plurality of through holes, and the placement plate is also provided with a plurality of through holes. By adopting the above technical solution, since the conveyor belt is provided with a plurality of through holes, the air circulation effect can be better during the swinging of the conveyor belt, thereby the drying speed is faster.

[0015] Optionally, a limiting assembly for limiting the position of the heat sink in the placement slot is provided on the drying box; the limiting assembly includes a limiting ring fixed to the side of the drying box and a limiting slot provided on the limiting ring, the limiting ring is sleeved on the rotating disk, and the placement plate is in the limiting ring, and when the limiting slot and the placement slot are connected, the heat sink in the placement slot is separated from the placement plate.

[0016] By adopting the above technical solution, the heat sink removed from the drying box is spun dry during the rotation of the rotating disk, and then the limiting ring can prevent the heat sink from leaving the placement slot during the rotation, and then when the placement slot and the limiting slot correspond, the heat sink in the placement slot automatically falls off.

[0017] Optionally, an arc-shaped abutment plate is rotatably provided on the inner wall of the limiting ring, and the arc-shaped abutment plate is used to support the end surface of the heat sink inclined downward in the placement groove, and a driving component for driving the arc-shaped abutment plate to rotate is provided on the limiting ring.

[0018] By adopting the above technical scheme, when the placement plate with the heat sink is rotated and tilted downward, the side of the heat sink will abut against the arc-shaped abutment plate, and then the driving component drives the arc-shaped abutment plate to rotate at the same speed as the rotating disk. At this time, the contact between the inclined heat sink and the limit ring can be reduced, and then the friction between the heat sink and the limit ring can be reduced. When the placement slot with the heat sink and the limit slot correspond to each other, the driving component drives the arc-shaped abutment plate to rotate in the opposite direction, and the rotating disk does not rotate. Then, the arc-shaped abutment plate and the heat sink here will no longer abut and limit, and then the heat sink in the placement slot will be separated from the placement slot, thereby achieving the purpose of automatic unloading.

[0019] Optionally, the arc-shaped abutment plate is rotatably connected to a side close to the placement plate with a plurality of universal balls, and the plurality of universal balls are used to contact the heat sink in the placement groove.

[0020] By adopting the above technical solution, due to the setting of the universal ball, when the arc-shaped abutment plate moves in the reverse direction, the friction between the arc-shaped abutment plate and the heat sink can be reduced.

[0021] Optionally, the driving assembly includes a large ring gear fixed on the arc-shaped abutment plate, a gear rotatably connected to the drying box body, and a driving motor fixed to the drying box body, the large ring gear is rotatably connected to the limit ring, and the gear and the large ring gear are meshed, and the output shaft of the driving motor is fixedly connected to the gear.

[0022] By adopting the above technical solution, when the arc-shaped abutment plate needs to rotate, the driving motor drives the gear to rotate, the gear drives the large gear ring to rotate, and then the arc-shaped abutment plate is driven to rotate through the large gear ring.

[0023] Optionally, a support frame is provided on the drying box body, and a transfer component for transferring the heat sink detached from the limiting groove is provided on the support frame, and the transfer component includes two transfer rollers rotatably connected to the support frame, a transfer belt wound around the transfer rollers, and a transfer motor fixed on the support frame.

[0024] By adopting the above technical solution, when the heat sink falls from the limiting groove onto the rotating belt, the rotation of the transfer belt can drive the heat sink to better leave the placement groove.

[0025] In summary, the present application includes at least one of the following beneficial technical effects: 1. The two adjacent swing frames drive the heat sink to swing back and forth at intervals along the width direction of the conveyor belt in the drying box. During the swinging process of the heat sink, the originally relatively static air will form airflow due to the swinging of the heat sink, and then accelerate the flow of air in the drying box. When the air flow is accelerated, the drying speed of the heat sink can be increased, thereby reducing the drying time of the heat sink.

[0026] 2. The heat sink removed from the drying box enters the placement slot, and then the rotating disk rotates, driving the heat sink in the placement slot to rotate, which will accelerate the evaporation of water on the surface of the heat sink, thereby achieving a better drying effect for the heat sink.

[0035] The following combination Figure 1-Figure 7This application is described in further detail.

[0036] Embodiment 1: The present application discloses a drying device for heat sink production. Figures 1 to 3 A drying device for producing heat sinks comprises a drying box 1 and a conveyor belt 11 arranged in the drying box 1. The conveyor belt 11 is arranged along the length direction of the drying box 1. At the same time, a motor is arranged on the drying box 1. The motor can drive the conveyor belt 11 to rotate in the drying box 1, and then the heat sink to be dried can be transported to the drying box 1. In addition, a swing component 2 is arranged in the drying box 1. The swing component 2 is used to drive the transported heat sink to swing left and right in the drying box 1 along the width direction of the conveyor belt 11, so as to increase the air flow in the drying box 1, and then the drying speed of the heat sink can be accelerated.

[0037] Reference Figures 1 to 3 The swing assembly 2 includes a mounting frame 21, a swing shaft 22 and a swing frame 23. Two mounting frames 21 are provided. The two mounting frames 21 are provided at both ends of the drying box 1 and are fixed on the drying box 1. The swing shaft 22 is rotatably connected to the mounting frame 21. At least two swing shafts 22 and swing frames 23 are provided. In this embodiment, two swing shafts 22 and two swing frames 23 are provided. The swing frame 23 is fixedly installed on the swing shaft 22. The swing shaft 22 is rotated to drive the swing frame 23 to swing back and forth at intervals along the width direction of the conveyor belt 11, and then the heat sink to be dried is moved between two adjacent swing frames 23. At the same time, the swing frame 23 can drive the heat sink to swing at the same time during the swinging process, thereby increasing the air flow and improving the drying speed of the heat sink.

[0038] Reference Figures 1 to 4 A control component 3 is provided on the drying box body 1 for driving the swing shaft 22 and the swing frame 23 to swing back and forth at intervals along the width direction of the conveyor belt 11. In this embodiment, the intermittent reciprocating swing means that when the swing frame 23 rotates to the extreme position on one side, there will be a pause for a period of time, and then continue to swing in the opposite direction. When the reverse swing reaches the extreme position, there will be a pause for a certain period of time, and the swing angle of the swing frame 23 and the pause time when it rotates to the extreme position can be set according to actual needs.

[0039] Before starting drying, the operator will place the heat sinks between two adjacent swing frames 23 at intervals in sequence. When placing the heat sinks, the heat sinks will be kept in a certain tilted state so that the tilted heat sinks can abut against one swing frame 23. Next, the conveyor belt 11 is started. The conveyor belt 11 will start to move at a uniform speed under the drive of power. Its main function is to drive the heat sinks between adjacent swing frames 23 to move steadily in the drying box 1; as the conveyor belt 11 rotates, the heat sinks will gradually move from one end of the drying box 1 to the other end. During the movement, the heating elements inside the drying box 1 will generate a large amount of hot air, which will continuously dry the heat sinks. The hot air is evenly wrapped around the surface of the heat sink, taking away the moisture on the surface of the heat sink, and gradually drying the heat sink.

[0040] However, in order to further improve the drying efficiency, reduce the drying time, and thus achieve the purpose of saving electricity, while the heat sink is moving, the two adjacent swing frames 23 are controlled to drive the heat sink to swing back and forth at intervals in the drying box 1. When the heat sink moves forward for a certain distance driven by the conveyor belt 11, the control component 3 will start the swing device of the swing frame 23, so that the swing frame 23 drives the heat sink to swing back and forth at intervals according to the set angle and frequency. On the one hand, this intermittent reciprocating swing will disturb the air around it, accelerate the flow speed of the air in the drying box 1, and the originally relatively static air will form an airflow due to the swinging of the heat sink, so that the hot air can cover every corner of the heat sink more quickly, further improving the efficiency of heat transfer. On the other hand, the accelerated air flow speed also helps to take away more water vapor, so that the drying process can be carried out more quickly. By swinging, not only can the drying quality of the heat sink be guaranteed, so that all parts of the heat sink can be fully dried, but also the drying time is greatly shortened. Compared with the traditional drying method, it effectively reduces energy consumption, plays a significant effect of saving electricity, and also improves production efficiency.

[0041] Reference Figures 1 to 3, a conveying assembly 4 is arranged on the swing frame 23, and the conveying assembly 4 is used to convey the heat sink between two adjacent swing frames 23, so as to reduce the friction between the heat sink and the swing frame 23; the conveying assembly 4 includes two conveying rollers 41 and a conveying belt 42 wound around the two conveying rollers 41, and the two conveying rollers 41 are both rotatably connected to the same swing frame 23, and a conveying motor (not shown in the figure) is fixedly installed on the swing frame 23, and the output shaft of the conveying motor is fixedly connected to one of the conveying rollers 41, and then when the conveying motor drives the conveying roller 41 to rotate, it will drive the conveying belt 42 to rotate, so as to convey the heat sink in the drying box 1; in this embodiment, the rotation speed of the conveying belt 42 is the same as the rotation speed of the conveyor belt 11, and the conveying assembly 4 is arranged, when the swing frame 23 is tilted, the heat sink in the drying box 1 will abut against the conveying belt 42 located below, and then during the conveying process, the friction of the heat sink can be reduced. In addition, in order to facilitate the heat of the drying box 1 to pass through the conveying belt 42, a plurality of through holes are opened on the conveying belt 42.

[0042] Reference Figures 2 to 4 The control assembly 3 includes a control rod 31, a connecting rod 32, a rotating block 33 and a control cylinder 34. The control rod 31 is slidably connected to the drying box body 1 along the width direction of the conveyor belt 11. The connecting rod 32 is fixed on the swing frame 23. The rotating block 33 is rotatably connected to the control rod 31, and the rotating block 33 is slidably connected to the connecting rod 32. The control cylinder 34 is installed on the drying box body 1, and the piston rod of the control cylinder 34 is fixed on the control rod 31. The control rod 31 is driven to reciprocate on the drying box body 1 by the control cylinder 34. During the movement of the control rod 31, due to the limitation of the connecting rod 32, the rotating block 33 will rotate on the control rod 31, and the rotating block 33 will slide on the connecting rod 32. Then the angle of the swing frame 23 can be adjusted. During the rotation of the swing frame 23, the conveyor belt 42 will be driven to swing along the axis of the swing shaft 22.

[0043] The implementation principle of a drying device for heat sink production in an embodiment of the present application is as follows: a worker places the heat sink between two swing frames 23 at intervals, and then conveys the heat sink through a conveyor belt 42 and a conveyor belt 11. During the conveying process, the control component 3 drives the swing frame 23 and the conveyor belt 42 arranged on the swing frame 23 to swing back and forth at intervals to the left and right, thereby increasing the air flow in the drying box 1, and then accelerating the drying speed of the heat sink.

[0044] Embodiment 2: The difference between the second embodiment and the first embodiment is that the heat sink removed from the drying box 1 can be further dried, thereby accelerating the evaporation rate of the water on the heat sink.

[0045] Reference Figure 5 to Figure 6Some of the heat sinks will still have some moisture after drying. Then, after being moved out of the drying box 1, they will move on the conveyor belt 11. At this time, since the heat sink has a certain temperature, the moisture on the heat sink will evaporate after moving a certain distance. A rotating component 5 is provided on the drying box 1. The rotating component 5 can drive the heat sink removed from the drying box 1 to rotate. At this time, the air flow is increased, so that the moisture on the heat sink evaporates faster.

[0046] Reference Figure 5 to Figure 6 The rotating assembly 5 includes a rotating disk 51, a placement plate 52 and a placement groove 53. A support frame 54 is fixedly installed on the drying box body 1. The rotating disk 51 is rotatably connected to the support frame 54, and the placement plate 52 is fixed on the rotating disk 51. A plurality of placement plates 52 are arranged on the rotating disk 51, and the plurality of placement plates 52 are evenly spaced along the circumference of the rotating disk 51. In this embodiment, six placement plates 52 are arranged, and each placement plate 52 is provided with a placement groove 53. Under the action of the placement groove 53, the placement plate 52 has openings in three directions, and then the dried heat sink can be transported to the placement groove 53 under the action of the conveyor belt 11 and the conveyor belt 42. In addition, since the heat sinks on the conveyor belt 11 are placed at intervals, when the dried heat sinks in the front move into the placement groove 53, the dried heat sinks in the rear are still being transported on the conveyor belt 11, and then the placement plates 52 and the heat sinks arranged in the placement groove 53 are driven to rotate by the rotating disk 51, thereby increasing the air flow and evaporating the residual water on the heat sink faster.

[0047] In order to facilitate the movement of the heat sink into the placement slot 53, in the initial state, one of the placement plates 52 is in an inclined state, and there will be a short pause when the conveyor belt 42 and the swing frame 23 rotate to the inclined state. At this time, the inclined heat sink will correspond to the placement plate 52 in the inclined state, and then move from the conveyor belt 11 to the placement slot 53. At this time, the heat sink at the rear is still being transported on the conveyor belt 11, and the heat sink moved to the placement slot 53 rotates under the action of the rotating disk 51, which will accelerate the drying of the heat sink in the placement slot 53. In addition, in this embodiment, a through hole is provided on the placement plate 52, so that during the rotation of the placement plate 52, air can be blown onto the heat sink in the placement slot 53.

[0048] Reference Figures 5 to 7 A limiting assembly 6 is provided on the support frame 54, and the limiting assembly 6 is used to limit the position of the rotating heat sink, so as to prevent the heat sink from being separated from the placement groove 53 during the rotation of the rotating disk 51; the limiting assembly 6 includes a limiting ring 61 fixed on the support frame 54 and a limiting groove 62 fixed on the limiting ring 61, and the opening of the limiting groove 62 is inclined, so that the heat sink inclined downward can be separated from the placement groove 53, thereby achieving the purpose of automatic unloading.

[0049] Reference Figures 5 to 7 A transfer assembly 7 is provided on the support frame 54, and the transfer assembly 7 is used to transport the heat sink that has separated from the placement groove 53; the transfer assembly 7 includes two transfer rollers 71 rotatably connected to the support frame 54 and a transfer belt 72 wound around the transfer rollers 71, and a transfer motor for driving one of the transfer rollers 71 to rotate is provided on the support frame 54, and the output shaft of the transfer motor is fixedly connected to one of the transfer rollers 71.

[0050] Reference Figures 5 to 7 , an arc-shaped abutment plate 8 is provided on the limiting ring 61, and the arc-shaped abutment plate 8 is used to block the placement groove 53 corresponding to the limiting groove 62. At the same time, a driving component 9 is provided on the support frame 54, and the driving component 9 is used to drive the arc-shaped abutment plate 8 to rotate. When the rotating disk 51 driving the heat sink rotates, the heat sink will rotate to a tilted downward state. At this time, the heat sink in a tilted downward state will abut on the arc-shaped abutment plate 8. At this time, the driving component 9 drives the arc-shaped abutment plate 8 to rotate at the same time. When the heat sink tilted downward corresponds to the limiting groove 62, the driving component 9 drives the arc-shaped abutment plate 8 to rotate in the opposite direction. At this time, the placement groove 53 is opened, and then the heat sink in the placement groove 53 can be easily moved from the limiting groove 62 to the transfer belt 72.

[0051] In addition, in order to reduce the friction between the arc-shaped abutment plate 8 and the heat sink when it rotates in the opposite direction, a plurality of universal balls 81 are rotatably connected to one end of the arc-shaped abutment plate 8 close to the placement plate 52, and the universal balls 81 abut against the heat sink tilted downward. Then, when the driving assembly 9 drives the arc-shaped abutment plate 8 to rotate in the opposite direction, rolling friction occurs between the universal balls 81 and the heat sink tilted downward, thereby reducing the friction between the arc-shaped abutment plate 8 and the heat sink. Finally, the opening of the limit groove 62 is opened, and the heat sink corresponding to the limit groove 62 will fall onto the conveyor belt 72 under the action of gravity, and then be packaged subsequently.

[0052] Reference Figures 5 to 7 The driving assembly 9 includes a large ring gear 91, a gear 92 and a driving motor 93. The large ring gear 91 is fixed on the arc-shaped abutment plate 8 and is rotatably connected to the limit ring 61. The gear 92 is rotatably connected to the support frame 54. At the same time, the gear 92 and the large ring gear 91 are meshed. The driving motor 93 is fixed on the support frame 54. The output shaft of the driving motor 93 is fixedly connected to the gear 92. The gear 92 is driven to rotate by the driving motor 93, and then the large ring gear 91 is driven to rotate by the gear 92, so that the large ring gear 91 drives the arc-shaped abutment plate 8 to rotate.

[0053] After the dried heat sink moves into the placement slot 53, the heat sink is tilted upward, and then the rotating disk 51 drives the placement plate 52 to rotate. During the rotation, the heat sink in the placement slot 53 is swung to accelerate the evaporation of water on the heat sink. When the placement plate 52 rotates to tilt downward, it will abut against the arc-shaped abutment plate 8. At this time, under the action of the driving component 9, the arc-shaped abutment plate 8 is driven to rotate, and the arc-shaped abutment plate 8 and the placement plate 52 rotate at the same time. During the rotation, the arc-shaped abutment plate 8 will block the limiting groove 62, and then when the placement slot 53 with the heat sink corresponds to the limiting groove 62, the driving component 9 drives the arc-shaped abutment plate 8 to rotate in the opposite direction, so that the limiting groove 62 is opened, and then the heat sink in the placement slot 53 will fall onto the transfer belt 72 through the limiting groove 62, thereby achieving the purpose of falling. The arc-shaped abutment plate 8 will reset during the reverse rotation. After the heat sink corresponding to the limiting groove 62 is unloaded, the rotating disk 51 rotates. During the rotation, some heat sinks will rotate to a tilted downward state. At this time, the heat sink tilted downward abuts against the arc-shaped abutment plate 8. Then the above steps are repeated to reduce the friction between the heat sink and the limiting ring 61 and reduce the wear of the heat sink.

[0054] 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.
