Description

Technical Field

[0001] The present application relates to the field of coffee production, and in particular to a method for producing drip coffee. Background Art

[0002] Drip coffee is a portable coffee brewed from ground coffee beans placed in a sealed filter bag. To use: tear the bag, stretch the paper plywood on both sides, and hang it over a cup. Slowly pour hot water over the bag and it's ready to drink. Drip coffee uses a drip method to brew the coffee, perfectly capturing the coffee's acidity, sweetness, bitterness, mellowness, and aroma.

[0003] During the production of existing drip coffee, the ground coffee powder is evenly loaded into the inner filter bag, and the filter bag is sealed. Then, a robot is used to package the sealed filter bag with coffee particles in the outer bag. Finally, a conveyor belt sends the packaged drip coffee out and waits for the operator to pack it into boxes.

[0004] The packaged drip coffee is either piled at the end of a conveyor belt, where operators directly pick up the coffee and pack it into boxes. Alternatively, the conveyor belt delivers the drip coffee into a collection basket, which is then transported by a trolley to the boxing area where operators pack the coffee. Therefore, after the automated packaging of the drip coffee is complete, manual counting of the coffee pods for each box is still required, resulting in low efficiency and potential for improvement. Summary of the Invention

[0005] In order to improve the degree of automation in the production process of drip coffee and improve production efficiency, the present application provides a production method of drip coffee.

[0006] In the first aspect, the present application provides a cartoning device for drip coffee using the following technical solution:

[0007] A cartoning device for drip coffee comprises a packaging conveyor belt, a cartoning frame is provided at the tail end of the packaging conveyor belt, a packaging guide assembly is provided on the cartoning frame, the cartoning frame is located below the packaging conveyor belt and is slidably provided with a packaging pre-storage assembly to pre-storage coffee bags guided by the packaging guide assembly; an outer box conveyor belt is provided below the packaging pre-storage assembly, and the packaging pre-storage assembly packs the coffee bags into empty boxes on the outer box conveyor belt.

[0008] By adopting the above technical solution, after the coffee bags are packaged by the intelligent coffee packaging system, they are sequentially transported to the outside of the casing by the packaging conveyor belt. When the coffee bags are transported to the end of the packaging conveyor belt close to the cartoning frame, the coffee bags are in a horizontal state.

[0009] At this time, the coffee bag continues to move forward under the action of the packaging conveyor. When a part of the coffee bag protrudes from the packaging conveyor and is in a semi-suspended state, the packaging guide assembly guides the coffee bag to rotate around the end wall of the packaging conveyor. At this time, the coffee bag tilts and moves downward under the action of gravity, and is successfully received by the packaging pre-receiving assembly.

[0010] When the packaging pre-storage component stores one box of coffee bags, it sends the coffee bags into the empty boxes on the outer box conveyor belt. The operator collects the boxes filled with coffee bags at the terminal of the outer box conveyor belt and stores them in the warehouse.

[0011] The use of pre-packaging components replaces the need to manually count the number of coffee bags in a box, thereby increasing the degree of automation in the production process of drip coffee, improving production efficiency, and reducing errors in manual piece counting.

[0012] Optionally, the packaging guide assembly includes a guide cylinder and a guide roller, the guide cylinder is installed on the cartoning machine frame, the guide cylinder is installed above the packaging conveyor belt, the piston rod of the guide cylinder is connected to a guide frame, the guide roller is rotatably connected to the guide frame, and the length direction of the guide roller is consistent with the width direction of the packaging conveyor belt; the guide cylinder drives the guide roller to approach the packaging conveyor belt, and rotates the coffee bag in a horizontal state about the width direction of the packaging conveyor belt.

[0013] By adopting the above technical solution, the coffee bag is transported to the outside of the casing via the packaging conveyor belt. When a part of the coffee bag protrudes from the packaging conveyor belt, the guide cylinder is activated and the piston rod of the guide cylinder drives the guide roller to move downward. When the guide roller contacts the horizontal coffee bag, the guide roller continues to move downward. At this time, there is a gap between the guide roller and the packaging conveyor belt for the coffee bag to slide. At the same time, under the downward pressure of the guide roller, the coffee bag rotates about the width direction of the packaging conveyor belt, and the coffee bag rotates from a horizontal state to a vertical state. When gravity is greater than the friction between the coffee bag and the packaging conveyor belt, the coffee bag falls downward. At the same time, the continued downward movement of the guide roller has guided the coffee bag to a vertical state, and the coffee bag accurately falls to the packaging pre-storage assembly. The piston rod of the guide cylinder retracts and extends again to guide the next coffee bag. The guide cylinder drives the guide roller to guide each coffee bag, so that the coffee bag on the packaging conveyor belt can be smoothly moved to the packaging pre-storage assembly, thereby improving the accuracy of the cartoning equipment during operation.

[0014] Optionally, the packaging pre-storage component includes a pre-storage rack, a pre-storage box and a pre-storage screw, the pre-storage rack is installed on the cartoning machine frame, and the pre-storage rack is located below the packaging conveyor belt; the pre-storage screw is rotatably connected to the pre-storage rack, the pre-storage screw rotates synchronously with the outer box conveyor belt, the pre-storage box is threadedly connected to the pre-storage screw, the pre-storage box moves back and forth along the pre-storage screw, and the pre-storage box is located above the outer box conveyor belt; the top and bottom of the pre-storage box are both open, the pre-storage box stores coffee bags that are guided by the packaging guide component and fall into the pre-storage box, and puts several stored coffee bags into the empty box on the outer box conveyor belt, and a limiting member is provided at the bottom of the pre-storage box, and the limiting member intermittently limits the coffee bags stored in the pre-storage box.

[0015] Optionally, the limiting member includes a limiting plate and an unlocking column, the two limiting plates are rotatably connected to the bottom wall of the pre-storage box through a torsion spring, and the limiting plate is protruded and arranged at the bottom of the pre-storage box; the two unlocking columns are respectively fixed to the pre-storage rack at both ends of the pre-storage screw rod, and the diameter of the unlocking column gradually decreases from the pre-storage rack to the pre-storage box, and the limiting plate is provided with an unlocking plate that rotates synchronously with the limiting plate at both ends of the length direction of the pre-storage box, and the unlocking column can be inserted between the two unlocking plates located on the same side.

[0016] By employing this technical solution, as the coffee bags descend sequentially under the guidance of the guide rollers, the pre-storage box, driven by the pre-storage screw, moves from one end of the pre-storage rack to the other. During this movement, the unlocking post, inserted between the two release plates, slowly moves out. At this point, the two release plates, driven by the torsion spring, rotate toward the axis of the pre-storage box, while the limit plates simultaneously rotate from a vertical position to a parallel position. When the unlocking post is completely released from between the two release plates, both limit plates return to a parallel position.

[0017] At this point, one end of the pre-packaging box is positioned directly below the end of the packaging conveyor. Guided by the guide roller, the first coffee bag in that box smoothly falls into the pre-packaging box. The pre-packaging box continues to move, and the coffee bags on the packaging conveyor fall into the pre-packaging box one by one. When the last coffee bag in that box falls into the pre-packaging box, the unlocking pin at the end of the batch begins to enter the release gap. The unlocking pin contacts the curved surface of the release plate. As the diameter of the unlocking pin increases, the two release plates rotate away from each other, and the limit plate rotates. When the end wall of the unlocking pin contacts the end wall of the pre-packaging box, the limit plate rotates to complete the contact and limit the coffee bags, and several coffee bags fall into the empty boxes on the outer box conveyor. Simultaneously, the pre-packaging box moves in the opposite direction, repeating the above steps.

[0018] The mobile pre-storage box is used to match the transmission speed of the coffee bag. At the same time, the reciprocating pre-storage box and the positive and reverse storage method of the pre-storage box are used to reduce the resetting time of the pre-storage box and improve the box loading efficiency.

[0019] Optionally, the transmission direction of the outer box conveyor belt is perpendicular to the moving direction of the pre-storage box, and staggered cylinders are provided on both sides of the outer box conveyor belt. The staggered cylinders push the empty boxes on the outer box conveyor belt to make adjacent empty boxes staggered.

[0020] By adopting the above technical solution, two staggered cylinders are located on both sides, which push the empty boxes located in the middle of the outer box conveyor belt to both sides in the width direction of the outer box conveyor belt, so that the adjacent empty boxes are staggered; thereby, the coffee bags falling from both sides of the storage rack are packed into boxes respectively.

[0021] Optionally, a plurality of positioning protrusions are provided on both side walls in the width direction of the pre-storage box, and gaps for placing coffee bags are formed between adjacent positioning protrusions located on the same side wall.

[0022] By adopting the above technical solution, the positioning protrusions limit the side walls of the coffee bag, so that each coffee bag can only be inserted vertically between two positioning protrusions, reducing the occurrence of the coffee bag tilting after falling into the pre-storage box and improving the neatness of the coffee packaging.

[0023] In a second aspect, the present application provides a method for producing drip coffee using a cartoning device, which employs the following technical solutions:

[0024] A method for producing drip coffee using a cartoning device comprises the following steps:

[0025] Roasting: Weigh the weight of the coffee beans to be roasted and roast the weighed coffee beans;

[0026] Cooling and deodorization: Cool the roasted coffee beans and deodorize them.

[0027] Grinding: Grind the processed coffee beans and set the desired grinding fineness;

[0029] Cartoning: The packaged coffee bags are packed into boxes using cartoning equipment and stored in warehouses;

[0030] Random inspection: The packaged coffee is randomly inspected for quality, from net content to sealing, and then to visual inspection of the inner package after unpacking.

[0031] Optionally, in the roasting step, when the coffee beans are weighed, the roaster is preheated, and when the preheating temperature reaches 200° C., it is maintained for 10 minutes; after the roaster reaches the preheating temperature, the coffee beans are fed into the roaster for roasting.

[0032] Optionally, in the roasting step, the amount of gas introduced into the roaster is adjusted while the coffee beans are roasting.

[0033] Optionally, during the packaging step, the internal environment of the packaging is observed. If the inner package of powder is leaking, all packaging operations must be stopped immediately and the machine must be cleaned using high-pressure gas.

[0034] By adopting the above technical solution, the degree of automation in the production of drip coffee is improved by using cartoning equipment, and the production efficiency and quality of drip coffee are improved.

[0035] In summary, this application includes at least one of the following beneficial technical effects:

[0036] 1. After the coffee pods are packaged by the intelligent coffee packaging system, they are sequentially transported to the outside of the machine housing by the packaging conveyor belt.

[0045] The following is combined with Figure 1-5 This application is described in further detail.

[0046] The embodiment of the present application discloses a cartoning device for drip coffee. Figure 1 The cartoning equipment for drip coffee includes a packaging conveyor belt 1, one end of which is located inside the housing 11 of the intelligent coffee packaging system, and the other end extends out of the housing 11; the intelligent coffee packaging system packs the ground coffee particles into the inner bag, and the inner bag into the outer bag. After cutting, the coffee bag is separated from the wrapping paper and slides onto the packaging conveyor belt 1, and is then transferred out of the housing 11 by the packaging conveyor belt 1.

[0047] A cartoning rack 2 is installed at the end of the packaging conveyor 1 outside the housing 11. This rack is placed on the ground, to one side of the packaging conveyor 1. A package guide assembly 3 is installed on this rack, located above the packaging conveyor 1. A package pre-storage assembly 4 is slidably mounted below the cartoning rack 2, beneath which is an outer carton conveyor 5. This outer carton conveyor 5 runs perpendicular to the direction of the packaging conveyor 1.

[0048] After the coffee bag is packaged by the intelligent coffee packaging system, it is sequentially transferred to the outside of the casing 11 by the packaging conveyor belt 1. When the coffee bag is transferred to the end of the packaging conveyor belt 1 close to the cartoning frame 2, the coffee bag is in a horizontal state; at this time, the coffee bag continues to move forward under the action of the packaging conveyor belt 1. When a part of the coffee bag protrudes from the packaging conveyor belt 1 and is in a semi-suspended state, the packaging guide component 3 guides the coffee bag to rotate around the end wall of the packaging conveyor belt 1. At this time, the coffee bag tilts and moves downward under the action of gravity and is successfully received by the packaging pre-storage component 4; when the packaging pre-storage component 4 receives the number of coffee bags in a box, the packaging pre-storage component 4 sends the number of coffee bags in a box into the empty box of the outer box conveyor belt 5, and the operator collects the box full of coffee bags at the terminal of the outer box conveyor belt 5 and stores them in the warehouse.

[0049] Reference Figure 2 The packaging guide assembly 3 includes a guide cylinder 31, which is bolted to the cartoning frame 2. The guide cylinder 31 is mounted above the packaging conveyor 1 at one end of the housing 11, and the axis of the guide cylinder 31 does not pass through the packaging conveyor 1. In this embodiment, the guide cylinder 31 is positioned downward, meaning that the cylinder body of the guide cylinder 31 is located above its piston rod. A guide frame 33 is fixedly connected to the piston rod of the guide cylinder 31 via a snap-fit ​​connection. A guide roller 32 is rotatably connected to the guide frame 33. The length of the guide roller 32 aligns with the width of the packaging conveyor 1. In this embodiment, when the packaging conveyor 1 is transmitted in a clockwise direction, the guide roller 32 rotates counterclockwise, causing the guide roller 32 and the packaging conveyor 1 to move toward each other.

[0050] The coffee bag is transported to the outside of the casing 11 via the packaging conveyor belt 1. When a part of the coffee bag protrudes from the packaging conveyor belt 1, the guide cylinder 31 is activated and the piston rod of the guide cylinder 31 drives the guide roller 32 to move downward. When the guide roller 32 contacts the horizontal coffee bag, the guide roller 32 continues to move downward. At this time, there is a gap between the guide roller 32 and the packaging conveyor belt 1 for the coffee bag to slide. At the same time, the coffee bag rotates with the width direction of the packaging conveyor belt 1 as the axis under the downward pressure of the guide roller 32, and the coffee bag rotates from a horizontal state to a vertical state; when the gravity is greater than the friction force between the coffee bag and the packaging conveyor belt 1, the coffee bag falls downward. At the same time, the continuous downward movement of the guide roller 32 has guided the coffee bag to a vertical state, and the coffee bag accurately falls to the packaging pre-storage component 4; the piston rod of the guide cylinder 31 retracts and extends again to guide the next coffee bag.

[0051] Reference Figure 3 and Figure 4The packaging pre-storage assembly 4 includes a pre-storage rack 41, which is integrally formed on the cartoning frame 2 and located below the end of the packaging conveyor belt 1 near the guide cylinder 31. A pre-storage screw 43 is rotatably connected to the pre-storage rack 41. In this embodiment, the pre-storage screw 43 is a bidirectional screw. A pulley and belt are used to synchronize the transmission between one end of the pre-storage screw 43 and the outer box conveyor belt 5. To control the rotation speed of the pre-storage screw 43, the pulley on the pre-storage screw 43 can be replaced to accommodate different pulley sizes.

[0052] A pre-storage box 42 is slidingly arranged in the pre-storage rack 41. The length direction of the pre-storage box 42 is consistent with the length direction of the pre-storage screw rod 43. The pre-storage screw rod 43 passes through one side wall of the pre-storage box 42, and the other side wall of the pre-storage box 42 is penetrated by a guide rod 431; when the pre-storage screw rod 43 rotates, the pre-storage box 42 moves back and forth along the length direction of the packaging conveyor belt 1.

[0053] Figure 3 and Figure 4 The top and bottom of the pre-storage box 42 are both opened, and a number of positioning protrusions 421 are integrally formed on the side walls on both sides of the width direction of the pre-storage box 42. A gap for placing the coffee bag is formed between adjacent positioning protrusions 421 located on the same side wall; the coffee bag guided by the guide roller 32 falls directly between two adjacent positioning protrusions 421 of the pre-storage box 42.

[0054] A limiter 6 is provided at the bottom of the pre-storage box 42, which intermittently limits the position of the coffee pods stored in the pre-storage box 42. The limiter 6 includes a limit plate 61. In this embodiment, two limit plates 61 are provided. Both limit plates 61 are rotatably connected to the bottom wall of the pre-storage box 42 via a rotating shaft and a torsion spring. The two limit plates 61 are located on either side of the sliding direction of the pre-storage box 42, that is, the length direction of the limit plates 61 is consistent with the length direction of the pre-storage box 42.

[0055] The top wall of the limiting plate 61 abuts against the bottom wall of the pre-storage box 42, and the sides of the two limiting plates 61 that are closest to each other extend into the interior of the pre-storage box 42, allowing coffee pods dropped into the pre-storage box 42 to partially contact the limiting plates 61. Both limiting plates 61 have integrally formed release plates 63 at their longitudinal ends, creating a release gap between the two release plates 63 on the same side. The adjacent ends of the release plates 63 have a curved surface.

[0056] Unlocking posts 62 are bolted to both ends of the pre-storage rack 41, located in the direction of the pre-storage box 42's sliding motion. The axis of the unlocking posts 62 is parallel to the sliding direction of the pre-storage box 42, and the axis is positioned higher than the position of the unlocking posts 62. The diameter of the unlocking posts 62 gradually decreases from the pre-storage rack 41 toward the pre-storage box 42. In this embodiment, when one end of the release plate 63 contacts the pre-storage rack 41, the unlocking posts 62 are inserted into the release gap, and the end wall of the unlocking posts 62 contacts the end wall of the pre-storage box 42.

[0057] Reference Figure 4 and Figure 5 As the coffee packets descend one by one, guided by the guide rollers 32, the pre-storage box 42, driven by the pre-storage screw 43, moves from one end of the pre-storage rack 41 to the other. As the pre-storage rack 41 moves, the unlocking post 62, inserted between the two release plates 63, slowly moves out. At this point, the release plates 63, driven by the torsion springs, rotate toward the axis of the pre-storage box 42. Simultaneously, the limit plates 61 rotate from a vertical position to a parallel position. When the unlocking post 62 is completely released from between the release plates 63, the limit plates 61 return to a parallel position.

[0058] At this time, one end of the pre-storage box 42 is just below the end of the packaging conveyor belt 1. The first coffee bag of the box falls smoothly into the pre-storage box 42 under the guidance of the guide roller 32. The pre-storage box 42 continues to move, and the coffee bags on the packaging conveyor belt 1 fall into the pre-storage box 42 one by one; when the last coffee bag of the box falls into the pre-storage box 42, the unlocking column 62 located at the tail end of the batch of movement begins to enter the release gap, and the unlocking column 62 and the arc surface of the release plate 63 are abutted, and as the diameter of the unlocking column 62 increases, the two release plates 63 rotate away from each other, and at this time the limit plate 61 rotates; when the end wall of the unlocking column 62 contacts the end wall of the pre-storage box 42, the limit plate 61 rotates to complete the contact and limit the coffee bag, and several coffee bags fall into the empty box on the outer box conveyor belt 5. At the same time, the pre-storage box 42 moves in the opposite direction to repeat the above steps, so that the empty boxes on the outer box conveyor belt 5 are staggered to receive the coffee bags after the pre-storage box 42 is released once at each end of the pre-storage rack 41.

[0059] Reference Figure 1 The outer box conveyor belt 5 conveys the empty box toward the pre-storage box 42. Offset cylinders 51 are provided on both sides of the width direction of the outer box conveyor belt 5. The two offset cylinders 51 are fixed to the frame of the outer box conveyor belt 5 by bolts, and the axes of the two offset cylinders 51 are parallel to the width direction of the outer box conveyor belt 5, but the axes of the two offset cylinders 51 are not collinear.

[0060] When the piston rod of the offset cylinder 51 is extended, the empty box originally located in the middle of the outer box conveyor belt 5 can be pushed to one side. The two offset cylinders 51 on both sides respectively push the empty box located in the middle of the outer box conveyor belt 5 to both sides in the width direction of the outer box conveyor belt 5, so that the adjacent empty boxes are staggered; thereby, the coffee bags falling from both sides of the pre-storage rack 41 are boxed respectively; the operator directly covers the finished products that have been boxed at the end of the transportation of the outer box conveyor belt 5 and stacks them for storage.

[0061] In other embodiments, a housing may be mounted on the exterior of the entire cartoning device.

[0062] The implementation principle of the cartoning equipment for drip coffee in the embodiment of the present application is as follows: after the coffee bags are packaged by the intelligent coffee packaging system, they are sequentially transferred to the outside of the casing 11 by the packaging conveyor belt 1. When the coffee bags are transferred to the end of the packaging conveyor belt 1 close to the cartoning frame 2, the coffee bags are in a horizontal state; at this time, the coffee bags continue to move forward under the action of the packaging conveyor belt 1. When a part of the coffee bags protrudes from the packaging conveyor belt 1 and is in a semi-suspended state, the packaging guide component 3 guides the coffee bags to rotate around the end wall of the packaging conveyor belt 1. At this time, the coffee bags are tilted and move downward under the action of gravity, and are successfully received by the packaging pre-storage component 4; when the packaging pre-storage component 4 receives the number of coffee bags in a box, the packaging pre-storage component 4 sends the number of coffee bags in a box into the empty box of the outer box conveyor belt 5, and the operator collects the boxes filled with coffee bags at the terminal of the outer box conveyor belt 5 and stores them in the warehouse.

[0063] The present application also discloses a method for producing drip coffee using a cartoning device. The method comprises the following steps:

[0064] Roasting: Weigh the weight of the coffee beans to be roasted. While weighing the coffee beans, preheat the roaster and keep the preheating temperature at 200℃ for 10 minutes. After the roaster reaches the preheating temperature, send the coffee beans into the roaster for roasting. At this time, the coffee beans will undergo reactions such as Maynard and caramelization in the warehouse to give the coffee a specific flavor.

[0065] When roasting coffee beans, adjust the amount of air entering the roaster to adjust the flavor of different coffee beans; at the same time, observe the changes in the ROR curve. The ROR curve reflects the trend and pattern of temperature rise. The roasting curve is a changing curve chart of temperature rise or fall during the roasting process, recording the temperature of the coffee beans and hot air; it is necessary to constantly observe and control the color value and oil yield of the coffee beans to ensure the flavor characteristics of the drip coffee.

[0066] Cooling and deodorization: The roasted coffee beans are cooled to preserve the flavor of the coffee beans, and the cooled coffee beans are deodorized to ensure the subsequent grinding.

[0067] Grinding: Grind the processed coffee beans and set the desired grinding fineness.

[0068] Packaging: Ground coffee is placed into the hopper of the intelligent coffee packaging system and sequentially packaged in inner and outer bags. Powered by electricity and compressed air, the system employs vacuum loading, automatic powder filling, and internal and external packaging. The internal packaging environment is monitored. If the inner bag of powder leaks, all packaging operations must be stopped immediately, and the machine must be cleaned with high-pressure air.

[0069] Cartoning: The packaged coffee bag is conveyed out via the packaging conveyor belt 1 of the intelligent coffee packaging system. When the coffee bag is transported to the tail end of the packaging conveyor belt 1, the piston rod of the guide cylinder 31 extends and the guide roller 32 presses the horizontal coffee bag downward.

[0070] As the coffee packets descend, guided by the guide rollers 32, the pre-storage box 42, driven by the pre-storage screw 43, moves from one end of the pre-storage rack 41 to the other. As the pre-storage rack 41 moves, the unlocking post 62, inserted between the two release plates 63, slowly moves out. At this point, the release plates 63, driven by the torsion springs, rotate toward the axis of the pre-storage box 42. Simultaneously, the limit plates 61 rotate from a vertical position to a parallel position. When the unlocking post 62 is completely released from between the release plates 63, the limit plates 61 return to a parallel position.

[0071] At this time, one end of the pre-storage box 42 is just below the end of the packaging conveyor belt 1. The first coffee bag in the box falls smoothly into the pre-storage box 42 under the guidance of the guide roller 32. The pre-storage box 42 continues to move, and the coffee bags on the packaging conveyor belt 1 fall into the pre-storage box 42 one by one. When the last coffee bag in the box falls into the pre-storage box 42, the unlocking column 62 at the tail end of the batch movement begins to enter the release gap. The unlocking column 62 and the arc surface of the release plate 63 are against each other, and as the diameter of the unlocking column 62 increases, the two release plates 63 rotate away from each other, and at this time the limit plate 61 rotates.

[0072] When the end wall of the unlocking post 62 contacts the end wall of the pre-storage box 42, the limiting plate 61 rotates to completely limit the coffee packets, and several coffee packets fall into the empty boxes on the outer box conveyor 5. Simultaneously, the pre-storage box 42 moves in the opposite direction, repeating the above steps. Thus, the empty boxes on the outer box conveyor 5 are staggered to receive the coffee packets that have been unlocked by the pre-storage box 42 at each end of the pre-storage rack 41. The packaged coffee packets are then boxed by the cartoning equipment and stored in the warehouse.

[0073] Random inspection: The packaged coffee is randomly inspected for quality, from net content to sealing, and then to visual inspection of the inner package after unpacking.

[0074] The above are all preferred embodiments of the present application, and are not intended to limit the scope of protection of the present application. Therefore, any equivalent changes made based on the structure, shape, and principle of the present application should be included in the scope of protection of the present application.
