Description

Technical Field

[0001] This application relates to the field of grain detection technology, and in particular to an automatic detection device for brewing mash. Background Technology

[0002] In the brewing industry, quality testing of raw mash (including testing for moisture, acidity, and starch in samples) is essential. This is typically done using a near-infrared spectroscopy (NIRS) instrument. Before and after testing, the mash needs to be placed in petri dishes, which are then transferred to the NIRS instrument's detection window for testing. After testing, the raw materials are cleaned, and the petri dishes are washed for future use. This testing process generally involves manual operation at each stage, supplemented by multiple instruments and equipment. The coordination between each step is largely manual, resulting in low efficiency. Utility Model Content

[0003] In order to overcome the problems existing in the prior art, this application provides an automatic detection device for fermented mash.

[0004] The automatic detection device for fermented mash provided in this application adopts the following technical solution:

[0005] An automatic detection device for fermented mash includes a feeding cabinet and a detection platform. The feeding cabinet contains several sets of containers for placing sampling cups. The detection platform is installed at the discharge end of the feeding cabinet and includes a sampling mechanism, a cleaning mechanism, a detection mechanism, and a robotic arm for transferring items between the aforementioned mechanisms and the containers. The sampling mechanism includes a barcode scanning station, a flipping station, and a flattening station. The barcode scanning station is located between the containers and the flipping station. The flipping station includes a placement platform with multiple clamping seats. The flattening station is located above the placement platform and distributed along its length, including a crossbeam and a flattening mechanism that moves along the length of the crossbeam. The cleaning mechanism includes a base and a working station mounted on the base. The base is fixedly installed on the detection platform, with a drain outlet at the center of the base. The top of the working station has several working slots, and a cleaning terminal and a drying terminal are installed at the bottom center of each working slot.

[0006] By adopting the above technical solution, when the automatic fermentation mash detection device is working, several containers equipped with sampling cups are placed in the feeding cabinet. After the device is started, the robotic arm removes the containers from the feeding cabinet from the discharge end and transports the sampling cups from the containers to the detection platform. First, the containers reach the sampling mechanism, where the barcode is scanned at the barcode scanning station. Then, the containers move to the flipping station, where the clamping seats on the placement platform hold the sampling cups. The robotic arm opens the sampling cup lid and places it into the clamping seat on one side. Then, the sampling cup is flipped over, transferring the sample into a petri dish on the flipping station. Next, the flattening mechanism above the placement platform moves along the crossbeam to the corresponding position, flattening the fermentation mash in the petri dish. Finally, the robotic arm transfers the petri dish to the detection mechanism for testing. The entire process automates the fermentation mash detection workflow. After the sample is poured into the sampling cup and the sample in the petri dish is tested, the robotic arm can transport both to the cleaning mechanism. The base of the cleaning mechanism is fixed to the testing platform, and there is a drain outlet in the center of the base. In the working slot at the top of the workstation, the cleaning terminal and the drying terminal sequentially clean and dry the sampling cup and petri dish. Then, the cleaned sampling cup is transferred to the corresponding collection mechanism, and the petri dish is placed back into the clamping seat on the flipping mechanism for loading the next sample.

[0007] Preferably, the robotic arm has no less than five degrees of freedom, and the output end of the robotic arm is equipped with a suction cup and a gripper.

[0008] Preferably, the suction cup is located at the center of the end of the robot, and the grippers are symmetrically installed on both sides of the suction cup. The grippers include a base and a clamping plate, wherein the base is rotatably installed at the end of the robot, and the clamping plate adopts a U-shaped structure, including two sets of L-shaped clamping rods that can slide relative to each other.

[0009] Preferably, the L-shaped clamping rod includes an integrally formed sliding part and a clamping part, wherein the sliding part is slidably connected to the limiting groove at the end of the base, and an adjusting rack is installed on the opposite surface of the sliding part on both sets of L-shaped clamping rods, and the adjusting gear between the adjusting rack and the sliding part meshes and drives.

[0010] By adopting the above technical solution, the robotic arm in the automatic fermentation mash detection device features a design with no fewer than five degrees of freedom, enabling it to move flexibly between various workstations. The suction cup at its output end is located at the center, with grippers symmetrically mounted on both sides. When the robotic arm begins operation, it first moves to the container placement area, where it can use the suction cup to pick up lighter items or the grippers to grasp them, depending on actual needs. The gripper base is rotatably mounted at the end of the robotic arm. The base can be rotated by the motor output shaft within the robotic arm, which is fixedly connected to the motor output shaft, facilitating angle adjustment. During the gripping operation, the U-shaped clamping plate comes into play, and its two sets of relatively sliding L-shaped clamping rods begin to operate. The L-shaped clamping rod consists of an integrally formed sliding part and a clamping part. The sliding part slides in the limiting groove at the end of the base. The adjusting rack and adjusting gear on the opposite surface of the sliding part of the two sets of L-shaped clamping rods mesh and drive each other. By rotating the adjusting gear, the relative distance between the two sets of L-shaped clamping rods can be precisely controlled, thereby firmly clamping items of different sizes. For example, in the process of handling and placing containers, sampling cups, etc., the clamping force and range can be flexibly adjusted according to the size of the object. Then, the items are accurately transferred to the designated positions such as the barcode scanning station, flipping station, flattening station, cleaning mechanism work station, and testing mechanism, completing the material handling task in the entire automatic fermentation mash testing process.

[0011] Preferably, the testing platform has a receiving cavity, which contains a receiving bucket, a cleaning water tank, and an air pump. The receiving bucket is located at the bottom of the drain outlet. The cleaning water tank is connected to the cleaning terminal through a cleaning water pipe. A cleaning pump is installed at one end of the cleaning water pipe in the cleaning water tank. The air inlet of the air pump is connected to the outside of the testing platform through a pipe, and a filter is installed at the air inlet. The air outlet of the air pump is connected to the drying terminal through a drying pipe.

[0012] By adopting the above technical solution, after the cleaning mechanism completes the cleaning operation on the sampling cup, the wastewater flows directly into the receiving bucket located at the bottom of the drain in the detection platform's containment cavity through the drain outlet at the bottom of the working tank, achieving centralized collection of wastewater and waste. The cleaning water tank provides a water source for the cleaning mechanism. The cleaning water tank is connected to the cleaning terminal through a cleaning water pipe. After the cleaning pump at one end of the cleaning water tank is started, it pressurizes the water in the tank and delivers it to the cleaning terminal, enabling the cleaning terminal to efficiently clean the sampling cup. At the same time, the air intake pump starts operating. Its air intake end is connected to the outside of the detection platform through a pipe. The filter installed at the air intake end filters the incoming air to ensure clean air enters. Subsequently, the air intake pump pressurizes the filtered air and delivers it to the drying terminal through the drying pipe. The drying terminal uses this high-pressure air to dry the cleaned sampling cup. Depending on different needs, a heating resistance wire can be added to the drying pipe to add a drying function, preparing for subsequent testing. All components work together to ensure the smooth progress of the cleaning and drying processes in the automatic testing process of the mash.

[0013] Preferably, the flattening mechanism includes a support frame and an L-shaped bracket fixedly installed on the top of the support frame. The support frame is slidably installed on the crossbeam. The threaded sleeve of the support frame located inside the crossbeam is connected to a lead screw distributed along the length of the crossbeam, and the lead screw is driven by a servo motor at the end of the crossbeam. A flattening cylinder is installed on the L-shaped bracket. The output end of the flattening cylinder passes through the L-shaped bracket, and a flattening block is installed on the free end of the L-shaped bracket. A limiting plate is also fixedly installed on the inner side of the L-shaped bracket to limit the output end of the flattening cylinder, and a through hole adapted to the output end of the flattening cylinder is provided on the limiting plate.

[0014] By adopting the above technical solution, when the automatic fermentation mash detection device reaches the flattening process, the servo motor at the end of the crossbeam starts, driving the lead screw to rotate. Since the support frame is slidably mounted on the crossbeam, and its sleeve inside the crossbeam is connected to the lead screw, the rotation of the lead screw drives the support frame to move along the length of the crossbeam, precisely adjusting the flattening mechanism to the position above the fermentation mash to be flattened. At this time, the flattening cylinder on the L-shaped bracket starts working, its output end extending downwards, and the flattening block installed through the free end of the L-shaped bracket descends accordingly. During the descent of the flattening cylinder's output end, the limiting plate fixedly installed inside the L-shaped bracket plays its role. The limiting plate has a through hole adapted to the output end of the flattening cylinder, limiting the movement trajectory of the output end and ensuring that the flattening block presses down vertically on the fermentation mash, achieving a uniform and stable flattening operation, meeting the sample processing requirements before fermentation mash detection.

[0015] Preferably, a large petri dish placement platform is installed between the cleaning mechanism and the testing mechanism, wherein the large petri dish placement platform adopts a multi-layer structure.

[0016] By adopting the above technical solution, after the cleaning mechanism completes the cleaning and drying of the sampling cups, the robotic arm transfers the processed samples from the cleaning mechanism to the large petri dish placement platform. Because the large petri dish placement platform has a multi-layered structure, it can orderly store multiple large petri dishes. The robotic arm will precisely place the samples into the corresponding number of petri dishes according to a preset program. After placement, if these samples are needed for subsequent testing, the robotic arm will retrieve the corresponding samples from the large petri dish placement platform and transport them to the testing mechanism. In this process, the large petri dish placement platform not only provides a temporary storage place for samples, but its multi-layered structure also optimizes space utilization, facilitating rapid sample retrieval by the robotic arm and ensuring an efficient and orderly connection between the cleaning and testing stages of the fermentation mash testing process.

[0017] Preferably, a display is also installed on the front of the detection platform, and the display is connected to the controller signal of the entire automatic fermentation mash detection device.

[0018] By adopting the above technical solution, during the operation of the automatic fermentation mash testing device, the controller of the entire device continuously collects and processes information from various mechanisms, such as the operating status and test data of each station. The display mounted on the front of the testing platform is connected to the controller and receives this information in real time. At the initial startup stage, the display shows the system initialization interface and the self-test results of each mechanism. During operation, it dynamically displays the remaining material in the feeding cabinet, the robotic arm's transport trajectory, and the execution progress of each operation step. After the testing mechanism completes the analysis of the fermentation mash sample, the display visually displays detailed test data, including the composition content and quality indicators of the fermentation mash. If a malfunction occurs, the display will promptly display an alarm, showing the location and cause of the fault, facilitating quick troubleshooting and repair by operators. Through close collaboration with the controller, the display provides operators with comprehensive and real-time information on the device's operation, ensuring the smooth operation of the automatic fermentation mash testing.

[0019] In summary, this application includes at least one of the following beneficial technical effects:

[0020] 1. This application's automatic fermentation mash detection device boasts significant advantages in hardware design and space utilization. It employs a multi-end robotic arm equipped with adjustable grippers and suction cups, enabling flexible handling of materials of varying sizes. The detection platform's internal cavity rationally houses components such as the receiving hopper and cleaning water tank. The large petri dish placement platform utilizes a multi-layered structure, effectively optimizing space utilization and facilitating sample storage and retrieval. Simultaneously, the display on the front of the detection platform is connected to the controller, providing real-time updates on operating status and detection data, and promptly triggering alarms in case of malfunctions, facilitating operator monitoring and maintenance.

[0021] 2. The device described in this application achieves full-process automation. The feeding cabinet, robotic arm, sampling mechanism, cleaning mechanism, and testing mechanism work together, greatly reducing manual intervention and improving testing efficiency. The sampling mechanism accurately records sample information through a barcode scanning station, securely fixes the sampling cup at the flipping station, and the flattening mechanism precisely controls the leveling of the mash. The cleaning mechanism, with the cooperation of a cleaning water tank, cleaning pump, air pump, and filter, efficiently completes the cleaning and drying work, avoiding cross-contamination and ensuring testing accuracy.

[0028] The following is in conjunction with the appendix Figure 1-5 This application will be described in further detail.

[0029] This application discloses an automatic detection device for fermented mash.

[0030] Reference Figure 1 , Figure 2 , Figure 3 , Figure 4 and Figure 5An automatic detection device for fermented mash includes a feeding cabinet 1 and a detection platform 2. The feeding cabinet 1 contains several sets of placement containers 11 for placing sampling cups. The detection platform 2 is installed at the discharge end of the feeding cabinet 1 and is equipped with a sampling mechanism 3, a cleaning mechanism 4, a detection mechanism 5, and a robotic arm 6 for transferring items between the above mechanisms and the placement containers 11. The sampling mechanism 3 includes a barcode scanning station 31, a flipping station 32, and a flattening station 33. The barcode scanning station 31 is located between the placement containers 11 and the flipping station 32. The flipping station 32 includes a placement table 321, in which the placement containers 11 are placed. The platform 321 has multiple clamping seats 322. The flattening station 33 is located above the platform 321 and is distributed along the length of the platform 321. It includes a crossbeam 331 and a flattening mechanism 332 that moves along the length of the crossbeam 331. The cleaning mechanism 4 includes a base 621 and a working station 42 installed on the base 621. The base 621 is fixedly installed on the detection platform 2. The base 621 has a drain outlet 411 in the center. The top of the working station 42 has several working grooves 421. The bottom center of the working groove 421 is equipped with a cleaning terminal 422 and a drying terminal 423. When the automatic fermentation mash detection device is working, several placement containers 11 with sampling cups are placed in the feeding cabinet 1. After the device is started, the robot arm 6 takes the placement containers 11 out of the feeding cabinet 1 from the discharge end and moves the sampling cups in the placement containers 11 to the detection platform 2. First, the sample reaches the sampling mechanism 3. At the barcode scanning station 31, the container 11 is scanned and identified. Then, it moves to the flipping station 32. The sampling cup is secured by the clamping seat 322 on the placement table 321. The robotic arm 6 opens the sampling cup lid and places it into the clamping seat 322 on one side. Then, the sampling cup is flipped, transferring the sample into a petri dish on the flipping station 32. Next, the flattening mechanism 332, located above the placement table 321, moves along the crossbeam 331 to the corresponding position, flattening the mash in the petri dish. Then, the robotic arm 6 transfers the petri dish to the detection mechanism 5 for testing. The entire process automates the mash testing process. After the sample is poured into the sampling cup and the sample in the petri dish is tested, the robotic arm 6 can transport both to the cleaning mechanism 4. The base 621 of the cleaning mechanism 4 is fixed on the testing platform 2. The base 621 has a drain outlet 411 in the center. In the working groove 421 at the top of the working station 42, the cleaning terminal 422 and the drying terminal 423 sequentially clean and dry the sampling cup and petri dish. Then, the cleaned sampling cup is transferred to the corresponding collection mechanism, and the petri dish is placed back into the clamping seat 322 on the flipping mechanism for loading the next sample.

[0031] Reference Figure 1The robotic arm 6 has six degrees of freedom. A suction cup 61 and grippers 62 are mounted on the output end of the robotic arm 6. The suction cup 61 is located at the center of the end of the robotic arm 6, and the grippers 62 are symmetrically mounted on both sides of the suction cup 61. Each gripper 62 includes a base 621 and a clamping plate 622. The base 621 is rotatably mounted on the end of the robotic arm 6. The clamping plate 622 has a U-shaped structure and includes two sets of L-shaped clamping rods 623 that can slide relative to each other. Each L-shaped clamping rod 623 includes an integrally formed sliding part 6231 and a clamping part 6232. The sliding part 6231 is slidably connected to a limiting groove at the end of the base 621, and adjusting racks 6233 are mounted on the opposite surfaces of the sliding parts 6231 on both sets of L-shaped clamping rods 623. Adjusting gears 6234 mesh between the adjusting racks 6233 and the sliding parts 6231 for transmission. In the operation of the automatic fermentation mash detection device, the robotic arm 6 adopts a design with no less than five degrees of freedom, enabling it to move flexibly between various workstations. Its output end has a suction cup 61 located at the center of the end, with grippers 62 symmetrically mounted on both sides. When the robotic arm 6 starts working, it first moves to the container 11, where it can use the suction cup 61 to pick up lighter items or use the grippers 62 to grasp them, depending on actual needs. The base 621 of the grippers 62 is rotatably mounted on the end of the robotic arm 6. The base 621 can be rotated by the motor output shaft located inside the robotic arm 6, which drives the base 621 to rotate, facilitating angle adjustment. During the grasping operation, the U-shaped clamping plate 622 comes into play, and its two sets of relatively sliding L-shaped clamping rods 623 begin to operate. The L-shaped clamp 623 consists of an integrally formed sliding part 6231 and a clamping part 6232. The sliding part 6231 slides in the limiting groove at the end of the base 621. The adjusting rack 6233 on the opposite surface of the sliding part 6231 of the two sets of L-shaped clamps 623 meshes with the adjusting gear 6234 for transmission. By rotating the adjusting gear 6234, the relative distance between the two sets of L-shaped clamps 623 can be precisely controlled, thereby firmly clamping items of different sizes. For example, during the handling and placement of containers 11, sampling cups, etc., the clamping force and range can be flexibly adjusted according to the size of the object. Then, the items are accurately transferred to the designated positions such as the barcode scanning station 31, the flipping station 32, the flattening station 33, the working station 42 of the cleaning mechanism 4, and the detection mechanism 5, thus completing the material handling task in the entire automatic detection process of the fermented mash.

[0032] Reference Figure 1 and Figure 2The testing platform 2 has a receiving cavity 21, which contains a receiving bucket 22, a cleaning water tank 23, and an air pump 24. The receiving bucket 22 is located at the bottom of the drain outlet 411. The cleaning water tank 23 is connected to the cleaning terminal 422 via a cleaning water pipe 231. A cleaning pump is installed at one end of the cleaning water pipe 231. The air inlet of the air pump 24 is connected to the outside of the testing platform 2 via a pipe, and a filter 241 is installed at the air inlet. The air outlet of the air pump 24 is connected to the drying terminal 423 via a drying pipe 242. After the working station 42 of the cleaning mechanism 4 completes the cleaning operation on the sampling cup, the wastewater will flow directly into the receiving bucket 22 located at the bottom of the drain outlet 411 in the receiving cavity 21 of the testing platform 2 through the drain outlet 411 at the bottom of the working tank 421, realizing the centralized collection of wastewater and waste. The cleaning water tank 23 provides water to the cleaning mechanism 4. The cleaning water tank 23 is connected to the cleaning terminal 422 via a cleaning water pipe 231. After the cleaning pump at one end of the cleaning water pipe 231 starts, it pressurizes the water in the tank and delivers it to the cleaning terminal 422, enabling the cleaning terminal 422 to efficiently clean the sampling cups. Simultaneously, the air intake pump 24 starts operating. Its air intake end is connected to the outside of the detection platform 2 via a pipe. The filter 241 installed at the air intake end filters the incoming air, ensuring clean air enters. Subsequently, the air intake pump 24 pressurizes the filtered air and delivers it to the drying terminal 423 via the drying pipe 242. The drying terminal 423 uses this high-pressure air to dry the cleaned sampling cups. Depending on different needs, a heating resistance wire can be added to the drying pipe 242 to add a drying function, preparing for subsequent testing. All components work together to ensure the smooth operation of the cleaning and drying processes in the automatic detection process of the fermented mash.

[0033] Reference Figure 1 , Figure 4 and Figure 5The flattening mechanism 332 includes a support frame 3321 and an L-shaped bracket 3322 fixedly installed on the top of the support frame 3321. The support frame 3321 is slidably installed on the crossbeam 331. The threaded sleeve of the support frame 3321 located inside the crossbeam 331 is connected to a lead screw distributed along the length of the crossbeam 331. The lead screw is driven by a servo motor 333 at the end of the crossbeam 331. A flattening cylinder 3323 is installed on the L-shaped bracket 3322. The output end of the flattening cylinder 3323 passes through the L-shaped bracket 3322, and a flattening block 3324 is installed on the free end of the L-shaped bracket 3322. A limiting plate 3325 is also fixedly installed on the inner side of the L-shaped bracket 3322 to limit the output end of the flattening cylinder 3323. The limiting plate 3325 has a through hole adapted to the output end of the flattening cylinder 3323. When the automatic fermentation mash detection device reaches the flattening process, the servo motor 333 at the end of the crossbeam 331 starts, driving the lead screw to rotate. Since the support frame 3321 is slidably mounted on the crossbeam 331, and its sleeve inside the crossbeam 331 is connected to the lead screw, the rotation of the lead screw drives the support frame 3321 to move along the length of the crossbeam 331, precisely adjusting the flattening mechanism 332 to the position above the fermentation mash to be flattened. At this time, the flattening cylinder 3323 on the L-shaped bracket 3322 starts to work, its output end extends downward, and the flattening block 3324 installed through the free end of the L-shaped bracket 3322 descends accordingly. During the descent of the output end of the flattening cylinder 3323, the limiting plate 3325 fixedly installed on the inner side of the L-shaped bracket 3322 plays a role. The limiting plate 3325 has a through hole that matches the output end of the flattening cylinder 3323, which limits the movement trajectory of the output end and ensures that the flattening block 3324 presses down on the mash vertically, achieving a uniform and stable flattening operation and meeting the sample processing requirements before mash testing.

[0034] Reference Figure 1 A large petri dish placement platform 7, with a multi-layered structure, is installed between the cleaning mechanism 4 and the testing mechanism 5. After the cleaning mechanism 4 completes the cleaning and drying of the sampling cups, the robotic arm 6 transfers the processed samples from the cleaning mechanism 4 to the large petri dish placement platform 7. Because the large petri dish placement platform 7 has a multi-layered structure, it can neatly store multiple large petri dishes. The robotic arm 6 will precisely place the samples into the corresponding layers of the large petri dishes according to a preset program. After placement, if these samples are needed for subsequent testing, the robotic arm 6 will retrieve the corresponding samples from the large petri dish placement platform 7 and transport them to the testing mechanism 5. In this process, the large petri dish placement platform 7 not only provides a temporary storage place for samples, but its multi-layered structure also optimizes space utilization, facilitating the robotic arm 6 to quickly access samples and ensuring that the fermentation mash testing process can be efficiently and orderly connected from cleaning to testing.

[0035] Reference Figure 1 and Figure 2The front of the detection platform 2 is also equipped with a display 8, which is connected to the controller of the entire automatic fermentation mash detection device. During operation, the controller continuously collects and processes information from various mechanisms, such as the operating status of each station and detection data. The display 8 on the front of the detection platform 2 is connected to the controller and receives this information in real time. At the initial startup stage, the display 8 shows the system initialization interface and the self-test results of each mechanism. During operation, it dynamically displays the remaining material in the feeding cabinet 1, the transport trajectory of the robotic arm 6, and the execution progress of each operation step. After the detection mechanism 5 completes the analysis of the fermentation mash sample, the display 8 displays detailed detection data intuitively, including the composition content and quality indicators of the fermentation mash. If a malfunction occurs, the display 8 will promptly display an alarm, showing the location and cause of the malfunction, facilitating quick troubleshooting and repair by operators. Through close collaboration with the controller, the display 8 provides operators with comprehensive and real-time information on the device's operation, ensuring the smooth operation of the automatic fermentation mash detection process.

[0036] Working principle: During operation, a container 11 containing a sampling cup is placed inside the loading cabinet 1. The robotic arm 6 uses the suction cup 61 at the center of its end and the symmetrical grippers 62 on both sides to pick up the sampling cup from the container 11 and move it to the barcode scanning station 31 for scanning. After that, it is transferred to the flipping station 32. The clamping seat 322 on the placement table 321 fixes the sampling cup. The robotic arm 6 opens the sampling cup lid and then puts the lid into the clamping seat 322 on one side. Then, it flips the sampling cup body and imports the sample from the sampling cup into the petri dish on the flipping station 32. The servo motor 333 drives the lead screw to move the support frame 3321, which in turn moves the L-shaped bracket 3322 and the flattening cylinder 3323 along the crossbeam 331. The flattening cylinder 3323 pushes the flattening block 3324 to flatten the mash in the petri dish. Then, the robotic arm 6 transfers the petri dish to the testing mechanism 5 for testing. Next, the robotic arm 6 transfers the sampling cup and petri dish to the working station 42 of the cleaning mechanism 4. Water from the cleaning tank 23, driven by the cleaning pump, is sprayed out through the cleaning pipe 231 and the cleaning terminal 422 to clean the sampling cup. The cleaning wastewater flows from the drain port 411 of the base 621 into the receiving hopper 22. Simultaneously, the air pump 24 draws in air through the filter 241, and the air is blown out through the drying pipe 242 and the drying terminal 423 to dry the sampling cup. The cleaned sampling cup is then transferred to the corresponding collection mechanism, and the petri dish is placed back into the clamping seat 322 on the flipping mechanism for loading the next sample. If a large petri dish is required for testing, the robotic arm 6 can retrieve it from the multi-layered large petri dish placement platform 7. The information and data from the entire process are fed back to the controller and displayed on the display 8 on the front of the detection platform 2.

[0037] 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.
