Description

Technical Field

[0001] This application relates to the field of dust control equipment, and in particular to a dual-fluid dry fog cannon. Background Technology

[0002] A dual-fluid dry fog cannon is a spraying device that uses two fluids—compressed air and a liquid (usually water or a chemical agent)—to produce fine mist droplets. This type of equipment is widely used in air purification, dust suppression, disinfection, cooling, and other applications requiring precise spray control.

[0003] In related technologies, existing fog cannons have nozzles with a very unidirectional spray direction, meaning they can only spray in one direction. This easily leads to poor nozzle diffusion, resulting in poor dust suppression near the installation location and hindering daily use. Furthermore, existing fog cannons have a large number of nozzles on their nozzles, producing 200µm water atomized particles. This easily leads to high water consumption, resulting in poor dust suppression near the installation location, wasting water resources, and hindering daily use. Summary of the Invention

[0004] This application provides a dual-fluid dry fog cannon, the purpose of which is to enable the nozzle to spray in different directions, while effectively reducing the number of nozzles, and the atomized particles are 1-10um, thereby effectively improving the diffusion range of the fog cannon spray, which is beneficial to increasing the dust suppression effect of the fog cannon and saving water.

[0005] This application provides a dual-fluid dry fog cannon, which adopts the following technical solution:

[0006] A dual-fluid dry fog cannon includes a mounting frame, a support frame, and an air guide tube. The support frame is rotatably mounted on the mounting frame, and the air guide tube is mounted on the top of the support frame. Multiple nozzles are evenly distributed at intervals along the periphery of the end of the air guide tube. A spray nozzle is provided at the end of each nozzle away from the air guide tube. The nozzle is slidably mounted on the nozzle along its length and rotates during the sliding process. A gear is rotatably mounted inside the nozzle, and a sliding member is installed inside the nozzle. The gear meshes with the sliding member, and the gear drives the sliding member to slide along the length of the nozzle during rotation. The end of the sliding member is connected to the nozzle.

[0007] By adopting the above technical solution, the support frame provides stable support for the air guide tube while driving the air guide tube to rotate through the rotating seat. As the air guide tube rotates, the nozzles on the air guide tube spray in different directions.

[0008] This setup utilizes gears and sliding components to slide the nozzle along the length of the nozzle head, allowing for adjustment of the nozzle's length. When dust suppression needs to be applied to more distant areas, workers don't need to push the entire fog cannon forward; they can simply slide the nozzle on the nozzle head further away. This makes it more convenient and efficient for workers to spray dust suppression at a distance. Simultaneously, as the nozzle slides further away, the spray angle can rotate, further increasing the spray range and thus enhancing the dust suppression effect of the fog cannon.

[0009] Preferably, a micro motor is installed inside the nozzle, which drives the gear to rotate. During the rotation, the gear drives the slider to slide back and forth. The slider is connected to the nozzle through a drive linkage.

[0010] By adopting the above technical solution, the sliding component drives the drive linkage to slide back and forth during the sliding process, and then drives the nozzle to slide on the nozzle head through the drive linkage.

[0011] Preferably, a hinge seat is provided horizontally between the drive link and the nozzle. One end of the hinge seat is connected to the drive link, and the other end of the hinge seat is hinged to the nozzle. The hinge seat is used to drive the nozzle to rotate.

[0012] By adopting the above technical solution, specifically, when the hinge seat slides forward, the end connected to the nozzle is hinged upward. At this time, the nozzle is driven to rotate upward by the hinge seat. As the driving linkage slides forward more, the angle at which the hinge seat drives the nozzle to tilt upward is greater. That is, as the nozzle slides towards the distance, the angle of its spray gradually tilts upward.

[0013] When the hinge seat slides backward, the end connected to the nozzle hinges downward. At this time, the nozzle is driven to rotate downward through the hinge seat. As the drive linkage slides backward more, the angle at which the hinge seat drives the nozzle downward is larger. In other words, the spray angle of the nozzle gradually decreases as it slides backward.

[0014] In summary, as the sliding component continuously slides back and forth, it drives the drive linkage to slide back and forth as well. During this process, the sliding of the drive linkage causes the hinge seat to continuously rotate the nozzle up and down. Simultaneously, the nozzle slides back and forth through the hinge seat, driven by the drive linkage and the sliding component. This means that the spray angle of the nozzle rotates up and down during the back-and-forth sliding, effectively increasing the spray range and improving the dust suppression effect of the fog cannon.

[0015] Preferably, the inner walls at both ends of the sliding member are integrally formed with a first tooth portion along its length direction, and the gear is provided with a second tooth portion and a smooth portion along its circumference, wherein the first tooth portion and the second tooth portion are meshed and connected.

[0016] By adopting the above technical solution, when the gear meshes with the sliding member, multiple teeth on its second tooth portion mesh with the first tooth portion on the sliding member. As the gear rotates counterclockwise under the drive of the micro motor, when the second tooth portion on the gear rotates to the top of the gear, it meshes with the first tooth portion on the upper inner wall of the sliding member. At this time, as the gear rotates counterclockwise, the sliding member slides backward under the meshing of the first and second gear portions. As the gear continues to rotate under the drive of the motor, when the second tooth portion on the gear rotates to the bottom of the gear, it meshes with the first tooth portion on the lower inner wall of the sliding member. As the gear rotates, the sliding member slides forward under the meshing of the first and second tooth portions. Furthermore, as the gear rotates, the second tooth portion alternately meshes with the first tooth portions at both ends of the sliding member to continuously drive the sliding member to slide back and forth.

[0017] Preferably, a mounting box is integrally formed on one side of the nozzle, and a piston is vertically mounted inside the mounting box. The piston is located at the end of the sliding member away from the nozzle, and a water storage cavity is formed between the end of the piston away from the sliding member and the inner wall of the mounting box. The water storage cavity is used to drive the piston to slide within the mounting box. A rack is mounted along the length of the nozzle at the end of the piston near the sliding member, and the piston is used to drive the rack to slide synchronously. A driven wheel assembly is added between the rack and the gear. During the process of sliding towards the sliding member, the rack meshes with the driven wheel assembly, and the driven wheel assembly drives the gear to rotate.

[0018] By adopting the above technical solution, the gears are not driven by a micro motor to rotate, which eliminates the need to install a micro motor inside the nozzle, thereby reducing the overall assembly difficulty of the fog cannon and making it more convenient to use.

[0019] Preferably, the driven wheel assembly includes a first driven wheel and a second driven wheel, the first driven wheel and the second driven wheel are meshed together, the first driven wheel is meshed on the top of the rack, the second driven wheel is located on one side of the gear, and the second driven wheel is rotatably connected to the gear via a shaft.

[0020] By adopting the above technical solution, the first driven wheel and the second driven wheel enable the piston to slide forward under the drive of water pressure, and simultaneously drive the gear to rotate. In turn, the gear drives the sliding member to slide back and forth, and the sliding member drives the nozzle to slide back and forth during the sliding process.

[0021] Preferably, a return spring is provided on the top of the mounting box in the horizontal direction, and the return spring is used to drive the piston and the rack to return to their original positions.

[0022] By adopting the above technical solution, when the water pressure in the water storage chamber disappears, the return spring restores its deformation and drives the piston to slide away from the sliding member. At this time, the rack slides backward under the action of the piston to reset.

[0023] Preferably, the bottom of the mounting box has multiple water outlet holes, and the bottom of the nozzle is provided with a water storage box. The water outlet holes are connected to the water storage box, and the water outlet holes are used to drain the water in the water storage chamber into the water storage box.

[0024] By adopting the above technical solution, when the piston is in the initial position, the water outlet is located on the side of the piston away from the water storage chamber, and the water storage chamber is in a closed state. When water is injected into the water storage chamber through the water pipe, as the water pressure in the water storage chamber increases, it pushes the piston towards the water outlet. When the piston passes the water outlet, the water storage chamber is no longer closed, and the water in the water storage chamber is discharged to the outside of the nozzle through the water outlet. As water is continuously discharged from the water storage chamber, the water pressure in the water storage chamber gradually decreases. As the water pressure decreases, the piston slides away from the sliding member under the drive of the return spring, thereby causing the piston, return spring, and rack to return to their original positions.

[0025] When it is necessary to slide the nozzle further away, water in the water tank can be continuously injected into the water storage chamber through the water pipe to drive the piston to slide.

[0026] Preferably, the inner walls at both the upper and lower ends of the nozzle are provided with grooves along their length, and the upper and lower ends of the sliding member are integrally formed with sliding rods in the vertical direction, and the sliding rods slide in the corresponding grooves.

[0027] By adopting the above technical solution, the slide groove and slide rod guide the sliding component during the sliding process, which helps to ensure the stability of the sliding component during the sliding process inside the nozzle.

[0028] In summary, this application includes at least one of the following beneficial technical effects:

[0029] 1. The nozzle is slidably positioned along the length of the spray head using gears and sliding components, allowing for adjustment of the nozzle's length on the spray head. When dust suppression needs to be applied to more distant areas, workers do not need to push the entire fog cannon forward; they can simply slide the nozzle on the spray head further away. This makes it more convenient and efficient for workers to spray dust suppression at a distance. Simultaneously, the spray angle can rotate as the nozzle slides further away, further increasing the spray range and thus enhancing the dust suppression effect of the fog cannon.

[0030] 2. When the hinge seat slides forward, the end connected to the nozzle is hinged upward. At this time, the nozzle is driven to rotate upward through the hinge seat. As the driving linkage slides forward more, the angle at which the hinge seat drives the nozzle to tilt upward is greater. That is, as the nozzle slides towards the distance, the angle of its spray gradually tilts upward.

[0031] When the hinge seat slides backward, the end connected to the nozzle hinges downward. At this time, the nozzle is driven to rotate downward through the hinge seat. As the drive linkage slides backward more, the angle at which the hinge seat drives the nozzle downward is larger. In other words, the spray angle of the nozzle gradually decreases as it slides backward.

[0032] In summary, as the sliding component continuously slides back and forth, it drives the drive linkage to slide back and forth as well. During this process, the sliding of the drive linkage causes the hinge seat to continuously rotate the nozzle up and down. Simultaneously, the nozzle slides back and forth through the hinge seat, driven by the drive linkage and the sliding component. This means that the spray angle of the nozzle rotates up and down during the back-and-forth sliding, effectively increasing the spray range and improving the dust suppression effect of the fog cannon.

[0033] 3. When the piston is in the initial position, the water outlet is located on the side of the piston furthest from the water storage chamber, and the water storage chamber is closed in this state. When water is injected into the water storage chamber through the water pipe, the increased water pressure pushes the piston closer to the water outlet. When the piston passes the water outlet, the water storage chamber is no longer closed, and the water inside is discharged through the water outlet to the outside of the nozzle. As water is continuously discharged from the water storage chamber, the water pressure gradually decreases. As the water pressure decreases, the piston, driven by the return spring, slides away from the sliding component, thereby causing the piston, return spring, and rack to return to their original positions.

[0034] When it is necessary to slide the nozzle further away, water in the water tank can be continuously injected into the water storage chamber through the water pipe to drive the piston to slide. Attached Figure Description

[0041] The following is in conjunction with the appendix Figure 1 -Appendix Figure 5 This application will be described in further detail below.

[0042] Example 1:

[0043] This application discloses a dual-fluid dry fog cannon, referring to... Figure 1 and Figure 2 The system includes a mounting frame 1, a support frame 2, and an air guide duct 3. The mounting frame 1 is rectangular in shape and hollow inside. The support frame 2 is rotatably mounted on the mounting frame 1 via a corresponding rotating seat. The air guide duct 3 is mounted on top of the support frame 2. Multiple nozzles 4 are evenly distributed along the circumference of the end of the air guide duct 3. The end of each nozzle 4 away from the air guide duct 3 has a spray nozzle 5. While providing stable support for the air guide duct 3, the support frame 2 drives the air guide duct 3 to rotate via the rotating seat. As the air guide duct 3 rotates, the nozzles 5 on the air guide duct 3 spray in different directions.

[0044] The nozzle 4 is cylindrical in shape and hollow inside. The nozzle 5 is slidably mounted on the nozzle 4 along its length and can rotate at different angles during the sliding process.

[0045] This configuration allows the nozzle 5 to slide along the length of the nozzle head 4, making its length adjustable. When dust suppression needs to be applied to more distant areas, workers don't need to push the entire fog cannon forward; they can simply slide the nozzle 5 on the nozzle head 4 further away. This makes it more convenient and efficient for workers to spray dust suppression at greater distances. Furthermore, as the nozzle 5 slides further away, its spray angle can rotate, further increasing the spray range and enhancing the dust suppression effect of the fog cannon.

[0046] Specifically, refer to Figure 2 and Figure 3 Inside the nozzle 4, a sliding member 7 is slidably disposed along its length. A gear 6 is meshed on the sliding member 7, and the gear 6 is vertically arranged. A miniature motor is installed inside the nozzle 4, and the gear 6 can rotate clockwise or counterclockwise under the drive of the miniature motor 8. As the gear 6 rotates in both directions, the sliding member 7 slides back and forth inside the nozzle 4 under the meshing action of the gear 6. The end of the sliding member 7 is connected to the nozzle 5 through a drive linkage 9. One end of the drive linkage 9 is connected to the sliding member 7, and the other end of the drive linkage 9 is connected to the nozzle 5. During the sliding process, the sliding member 7 drives the drive linkage 9 to slide back and forth, which in turn drives the nozzle 5 to slide on the nozzle 4.

[0047] At the same time, refer to Figure 2 and Figure 3 A hinge seat 10 is horizontally provided between the drive link 9 and the nozzle 5. One end of the hinge seat 10 is connected to the drive link 9, and the other end of the hinge seat 10 is hinged to the nozzle 5. During the process of the sliding member 7 driving the drive link 9 to slide back and forth, the drive link 9 drives the hinge seat 10 to slide.

[0048] Specifically, when the hinge seat 10 slides forward, the end connected to the nozzle 5 is hinged upward. At this time, the nozzle 5 is driven to rotate upward through the hinge seat 10. As the driving link 9 slides forward more, the hinge seat 10 drives the nozzle 5 to tilt upward at a greater angle. That is, as the nozzle 5 slides towards the distance, the angle of its spray gradually tilts upward.

[0049] When the hinge seat 10 slides backward, the end connected to the nozzle 5 is hinged downward. At this time, the nozzle 5 is driven to rotate downward through the hinge seat 10. As the driving link 9 slides backward more, the angle at which the hinge seat 10 drives the nozzle 5 downward is larger. That is, the spray angle of the nozzle 5 gradually decreases as it slides backward.

[0050] In summary, as the sliding member 7 continuously slides back and forth, it drives the driving link 9 to slide back and forth as well. During this process, the sliding of the driving link 9 causes the hinge seat 10 to continuously rotate the nozzle 5 up and down. In this process, the nozzle 5 slides back and forth simultaneously through the hinge seat 10 under the drive of the driving link 9 and the sliding member 7. This means that the spray angle of the nozzle 5 continuously rotates up and down during the back-and-forth sliding process, effectively increasing the spray range of the nozzle 5 and improving the dust suppression effect of the fog cannon.

[0051] Specifically, refer to Figure 2 and Figure 3 A miniature cylinder 23 is mounted along the length of the bottom of the nozzle 4. The piston 14 of the miniature cylinder 23 faces the nozzle 5, and the piston 14 of the miniature cylinder 23 is connected to the bottom of the nozzle 5 via a vertically arranged hinge plate 24. During the back-and-forth sliding movement of the nozzle 5 driven by the drive linkage 9 through the hinge seat 10, the miniature cylinder 23 drives the bottom of the nozzle 5 to rotate in the same direction through the hinge plate 24. It should be noted that there is a speed difference between the speed at which the miniature cylinder 23 drives the nozzle 5 and the speed at which the drive linkage 9 drives the nozzle 5. This makes it easier for the nozzle 5 to hinge and rotate, resulting in more efficient rotation of the nozzle 5.

[0052] Specifically, refer to Figure 2 and Figure 3 The left and right ends of the slider 7 are semi-circular, while the top and bottom ends are elongated. The inner walls of the top and bottom ends of the slider 7 are integrally formed with first toothed portions 11 along their length direction, which enable the slider 7 to mesh with the gear 6.

[0053] Reference Figure 2 and Figure 3The gear 6 has a second toothed portion 12 and a smooth portion 13 along its circumference. The second toothed portion 12 consists of multiple teeth evenly distributed along the circumference of the gear 6, while the smooth portion 13 has no teeth. Specifically, when the gear 6 meshes with the sliding member 7, the multiple teeth on its second toothed portion 12 mesh with the first toothed portion 11 on the sliding member 7. As the gear 6 rotates counterclockwise under the drive of the micro motor 8, when the second toothed portion 12 on the gear 6 rotates to the top of the gear 6, in this state, the second toothed portion 12 on the gear 6 meshes with the first toothed portion 11 on the upper inner wall of the sliding member 7. At this time, as the gear 6 rotates counterclockwise, the sliding member 7 slides backward under the meshing of the first and second toothed portions of the gear 6. As gear 6 continues to rotate under the drive of the motor, when the second tooth 12 on gear 6 rotates to the bottom of gear 6, the second tooth 12 on gear 6 meshes with the first tooth 11 on the inner wall of the lower end of the slider 7. As gear 6 rotates, the slider 7 slides forward under the meshing of the first tooth 11 and the second tooth 12. Furthermore, as gear 6 rotates, the second tooth 12 alternately meshes with the first tooth 11 at both the upper and lower ends of the slider 7 to drive the slider 7 to continuously slide back and forth.

[0054] The implementation principle of a dual-fluid dry fog cannon in this application embodiment is as follows:

[0055] The nozzle 5 is slidably positioned along the length of the nozzle head 4, allowing for adjustment of its length. When dust suppression needs to be applied to more distant areas, workers do not need to push the entire fog cannon forward; they can simply slide the nozzle 5 on the nozzle head 4 further away. This makes it more convenient and efficient for workers to spray dust suppression at a distance. Simultaneously, the spray angle of the nozzle 5 can rotate as it slides further away, further increasing the spray range and thus enhancing the dust suppression effect of the fog cannon.

[0056] When gear 6 meshes with sliding member 7, multiple teeth on its second tooth portion 12 mesh with the first tooth portion 11 on sliding member 7. As gear 6 rotates counterclockwise under the drive of micro motor 8, when the second tooth portion 12 on gear 6 rotates to the top of gear 6, in this state, the second tooth portion 12 on gear 6 meshes with the first tooth portion 11 on the upper inner wall of sliding member 7. At this time, as gear 6 rotates counterclockwise, sliding member 7 slides backward under the meshing of the first and second gear portions 6. As gear 6 continues to rotate under the drive of the motor, when the second tooth 12 on gear 6 rotates to the bottom of gear 6, the second tooth 12 on gear 6 meshes with the first tooth 11 on the inner wall of the lower end of the slider 7. As gear 6 rotates, the slider 7 slides forward under the meshing of the first tooth 11 and the second tooth 12. Furthermore, as gear 6 rotates, the second tooth 12 alternately meshes with the first tooth 11 at both the upper and lower ends of the slider 7 to drive the slider 7 to continuously slide back and forth.

[0057] As the sliding member 7 slides back and forth, it drives the driving link 9 to slide back and forth as well. During this process, the sliding of the driving link 9 causes the hinge seat 10 to continuously rotate the nozzle 5 up and down. In this process, the nozzle 5 slides back and forth simultaneously through the hinge seat 10, driven by the driving link 9 and the sliding member 7. This means that the spray angle of the nozzle 5 rotates up and down simultaneously during the back-and-forth sliding, effectively increasing the spray range of the nozzle 5 and improving the dust suppression effect of the fog cannon.

[0058] Furthermore, referring to Figure 2 and Figure 3 The inner walls of both the upper and lower ends of the nozzle 4 are provided with long grooves 21 along their length. Both the upper and lower ends of the sliding member 7 are integrally formed with sliding rods 22 in the vertical direction. During the sliding movement of the sliding member 7 in the nozzle 4, the sliding rods 22 slide in the corresponding grooves 21. The grooves 21 and the sliding rods 22 guide the sliding member 7 during its sliding movement, which helps to ensure the stability of the sliding member 7 during its sliding movement in the nozzle 4.

[0059] Example 2:

[0060] The difference between this embodiment and Embodiment 1 is that...

[0061] The gear 6 is not driven by the micro motor 8, which eliminates the need to install the micro motor 8 inside the nozzle 4, thereby reducing the overall assembly difficulty of the fog cannon and making it more convenient to use.

[0062] Specifically, refer to Figure 3 and Figure 4A mounting box 25 is integrally formed on one side of the nozzle 4. A piston 14 is vertically mounted inside the mounting box 25, located at the end of the sliding member 7 away from the nozzle 5. A sealed water storage cavity 15 is formed between the end of the piston 14 away from the sliding member 7 and the inner wall of the mounting box 25. A water pipe is connected to the water storage cavity 15, and water is injected into the water storage cavity 15 through the water pipe. As the water pressure in the water storage cavity 15 increases, it drives the piston 14 to slide closer to the sliding member 7 within the mounting box 25. A rack 16 is mounted along the length of the nozzle 4 at the end of the piston 14 near the sliding member 7. When the piston 14 slides towards the sliding member 7, it drives the rack 16 to slide synchronously. A driven wheel assembly 17 is provided between the rack 16 and the gear 6. When the rack 16 slides towards the slider 7, it meshes with the driven wheel assembly 17, thereby triggering the driven wheel assembly 17, which drives the gear 6 to rotate. During the rotation, the gear 6 drives the slider 7 to slide back and forth through the first tooth portion 11 and the second tooth portion 12.

[0063] Specifically, refer to Figure 3 and Figure 4 The driven wheel assembly 17 includes a first driven wheel 171 and a second driven wheel 172, which are meshed together. The first driven wheel 171 is meshed on the top of the rack 16, and the second driven wheel 172 is located on one side of the gear 6. The second driven wheel 172 is rotatably connected to the gear 6 via a shaft. When the second driven wheel 172 rotates, it drives the gear 6 to rotate via the shaft. The first driven wheel 171 and the second driven wheel 172 are meshed together by an additional driven wheel. When the piston 14 slides forward under water pressure using the first driven wheel 171 and the second driven wheel 172, it synchronously drives the gear 6 to rotate. In turn, the gear 6 drives the sliding member 7 to slide back and forth. During the back and forth sliding process, the sliding member 7 drives the nozzle 5 to slide back and forth.

[0064] Furthermore, referring to Figure 3 and Figure 4 A return spring 18 is horizontally mounted on the top of the mounting box 25. Driven by water pressure, the piston 14 compresses the return spring 18, placing it in a compressed state. When the water pressure in the water storage chamber 15 disappears, the return spring 18 returns to its original shape, driving the piston 14 to slide away from the sliding member 7. At this time, the rack 16 slides backward under the influence of the piston 14 to reset.

[0065] Specifically, refer to Figure 3 and Figure 4The bottom of the mounting box 25 has multiple circular water outlet holes 19, which are evenly distributed along the width of the mounting box 25. When the piston 14 is in the initial position, the water outlet holes 19 are located on the side of the piston 14 away from the water storage chamber 15, and the water storage chamber 15 is in a closed state in this state. When water is injected into the water storage chamber 15 through the water pipe, as the water pressure in the water storage chamber 15 increases, it pushes the piston 14 toward the water outlet holes 19. When the piston 14 passes the water outlet holes 19, the water storage chamber 15 is no longer in a closed state, and the water in the water storage chamber 15 is discharged to the outside of the nozzle 4 through the water outlet holes 19. As the water in the water storage chamber 15 is continuously discharged, the water pressure in the water storage chamber 15 gradually decreases. As the water pressure decreases, the piston 14 slides away from the sliding member 7 under the drive of the return spring 18, thereby causing the piston 14, the return spring 18, and the rack 16 to return to their original positions.

[0066] Reference Figure 3 and Figure 4 A water storage box 20 is installed below the mounting box 25. The water storage box 20 is connected to the water outlet 19. The water in the water storage chamber 15 falls into the water storage box 20 through the water outlet 19 for recycling. When it is necessary to slide the nozzle 5 to a distance, the water in the water storage box 20 can continue to be injected into the water storage chamber 15 through the water pipe to drive the piston 14 to slide.

[0067] Example 3:

[0068] The difference between this embodiment and Embodiments 1 and 2 is that...

[0069] Reference Figure 5 A hydraulic cylinder 26 is mounted on the bottom of the nozzle 4 along its length. The cylinder body of the hydraulic cylinder 26 is connected to the bottom of the nozzle 4, and the drive rod of the hydraulic cylinder 26 is connected to the nozzle 5 through a hinge plate 24. In this embodiment, the pitching motion of the nozzle 5 is entirely hydraulically driven by the hydraulic cylinder 26. This method of adjusting the spray angle of the nozzle 5 is simple in structure and has high assembly efficiency.

[0070] The above are all preferred embodiments of this application, and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made in accordance with the structure, shape and principle of this application should be covered within the scope of protection of this application.
