[0001] This utility model belongs to the field of cleaning equipment technology, and in particular relates to an automated duct cleaning device. Background Technology

[0002] The tubing includes flexible tubing and rigid tubing, which are fluid transmission pipes used in pharmaceutical, food and beverage and biomedical fields. After the tubing is manufactured, workers need to remove the tubing from the material cart one by one, then wipe the dust off the outer wall of the tubing with a cloth, put the cleaned tubing back into the material cart, and finally transfer it to the next process for tube wall coating.

[0003] In this process, workers need to constantly pick up, put down, and wipe the tubing, which is not only time-consuming and labor-intensive, but also inefficient. Furthermore, there is a risk of incomplete or missed wiping, resulting in the cleanliness failing to meet standards and directly affecting the quality of the finished product in the next process. Therefore, it is necessary to design an automated tubing cleaning device to solve this problem. Utility Model Content

Detailed Implementation

[0019] The technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, and not all embodiments. Based on the embodiments of this application, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of this application. It is understood that the accompanying drawings are provided for reference and illustration only, and are not intended to limit this application. The connection relationships shown in the accompanying drawings are only for clear description and do not limit the connection method.

[0020] See appendix Figure 1 - Appendix Figure 9An automated conduit cleaning device includes a material cart 1, a machine body 2, a material transfer mechanism 3, and a wiping mechanism 4. The material cart 1 carries multiple conduits 6. The machine body 2 has an operating chamber 20 for the material cart 1 to enter and exit. A workstation plate 21 is located within the operating chamber 20, and the conduits 6 can be placed vertically on the workstation plate 21 in a suspended state. The material transfer mechanism 3 includes a first drive unit 31 and a material picking component 32. The material picking component 32 is located within the operating chamber 20 and is used to pick up and place the conduits 6. The first drive unit 31 is mounted on the machine body 2 and... The material handling component 32 is driven to move between the material cart 1 and the workstation plate 21 to transfer the guide tube 6; the wiping mechanism 4 includes a second drive unit 41, a cleaning component 42 and a wiping cloth 43. The cleaning component 42 is located in the operating cavity 20 and can drive the wiping cloth 43 to abut or move away from the guide tube 6 which is in a suspended state; the second drive unit 41 is mounted on the machine body 2 and driven to move the cleaning component 42 from top to bottom so that the wiping cloth 43 cleans the outer wall of the guide tube 6.

[0021] Specifically, during operation, the multiple tubes 6 produced and to be cleaned are first placed on the material cart 1, and the material cart 1 is pushed into the operating chamber 20. Then, the first drive unit 31 is activated to drive the material picking component 32 to pick up the tubes 6 to be cleaned one by one, and transfer the tubes 6 to the workstation plate so that the tubes 6 are suspended in the air and corresponding to the cleaning component 42. Then, the cleaning component 42 drives the wiping cloth 43 to come into contact with the outer wall of the tube 6. Finally, the second drive unit 41 is activated to drive the cleaning component 42 to move from top to bottom so that the wiping cloth 43 wipes and cleans the outer wall of the tube 6.

[0022] After the current conduit 6 is cleaned, the cleaning component 42 drives the wiping cloth 43 away from the conduit 6 to release the restriction. Then, the second drive unit 41 is activated to reset the cleaning component 42. At the same time, the first drive unit 31 is activated to drive the picking component 32 to take away the cleaned conduit 6 and transfer it back to the material cart 1 for placement. Then, the first drive unit 31 drives the picking component 32 to take away the next conduit 6 to be cleaned and transfer it to the workstation plate 21 for a new cleaning operation. The above operation is repeated until all the conduits 6 on the material cart 1 are cleaned. Then, the material cart 1 is pushed out of the operating chamber 20 to be transferred to the next process for processing.

[0023] In summary, this utility model, by setting up a material cart 1 to centrally carry the conduit 6, by setting up a material transfer mechanism 3 inside the machine body 2 to automatically transfer the hoses on the material cart 1 one by one to the workstation plate 21 for suspension, and by setting up a wiping mechanism 4 inside the machine body 2 to automatically clean the guide rail in the suspended state; the whole process is not only highly automated and saves time and labor, but also avoids incomplete or missed wiping to ensure cleanliness, effectively improving work efficiency, cleaning effect and finished product quality.

[0024] It should be noted that the conduit 6 can be a flexible tube made of flexible materials such as silicone, or a rigid tube made of rigid materials such as PVC, and the wiping cloth 43 can be a lint-free cloth, etc. Since there are various types of conduits 6 and wiping cloths 43, and both can be used in this cleaning device, this utility model does not limit them.

[0025] See appendix Figure 4 - Appendix Figure 7 The material cart 1 is equipped with a carrier plate 11 and a receiving cavity 10. The carrier plate 11 is equipped with a movable groove 110 and multiple first locking holes 111. The movable groove 110 connects the receiving cavity 10 to the outside, and the first locking holes 111 have a first notch 112 that connects to the movable groove 110. The workstation plate 21 is equipped with at least one second locking hole 211, which has a second notch 212 that connects to the outside. The top end of the guide tube 6 is equipped with a connecting post 61 having a locking block 611, connecting... The column 61 can enter and exit the first locking hole 111 and the second locking hole 211 through the first notch 112 and the second notch 212 respectively, so that the locking block 611 can abut against the bottom wall of the first locking hole 111 and the bottom wall of the second locking hole 211 respectively; the material picking member 32 can clamp / adsorb the connecting column 61, and the first driving part 31 can drive the material picking member to move and enter and exit the first locking hole 111, the movable groove 110 and the second locking hole 211, so as to facilitate the picking and placing of the guide tube 6 on the carrier plate 11 or the work station plate 21.

[0026] Specifically, when it is necessary to transfer the conduit 6 on the carrier plate 11 to the workstation plate 21, the first drive unit 31 is activated to drive the picking member 32 to move down to clamp / adsorb the connecting column 61. Then, the picking member 32 is driven to move up so that the clamping block 611 moves away from the bottom wall of the first clamping hole 111, and the connecting column 61 is driven to move outward from the first notch 112 and into the movable groove 110, so that the conduit 6 can be separated from the carrier plate 11. At this time, the first drive unit 31 drives the picking member 32 to move along the movable groove 110 to transfer the conduit 6 to the side of the workstation plate 21. Then, the first drive unit 31 drives the connecting column 61 to move inward from the second notch 212 and into the second clamping hole 211. Finally, the picking member 32 is driven down so that the clamping block 611 abuts against the bottom wall of the second clamping hole 211, and the picking member 32 is controlled to release the connecting column 61, so that the conduit 6 can be suspended on the workstation plate 21 for the wiping mechanism 4 to perform cleaning operations.

[0027] Similarly, when it is necessary to transfer the conduit 6 on the workstation plate 21 to the carrier plate 11, the first drive unit 31 is activated to drive the picking member 32 to move down to clamp / adsorb the connecting column 61. Then, the picking member 32 is driven up to move the clamping block 611 away from the bottom wall of the second clamping hole 211, and the connecting column 61 is driven to move outward from the second notch 212 to detach from the workstation plate 21. At this time, the first drive unit 31 continues to drive the picking member 32 to move along the movable groove 110 until the connecting column 61 is aligned with the first notch 112. Then, the connecting column 61 is driven to move inward along the first notch 112 into the first clamping hole 111. Finally, the picking member 32 is driven down to move the clamping block 611 against the bottom wall of the first clamping hole 111, and the picking member 32 is controlled to release the connecting column 61, so that the cleaned conduit 6 can be placed on the carrier plate 11.

[0028] In summary, the above structural design allows the first drive unit 31 to drive the material handling component 32 to move upward slightly to detach the guide tube 6 from the carrier plate 11 or the workstation plate 21. Therefore, it is not necessary to reserve too much upward space for the first drive unit 31, which can effectively reduce the height of the operating cavity 20 to reduce the volume of the machine body 2 and reduce the space occupied by the machine body 2. At the same time, it is also convenient to quickly pick up and put down the guide tube 6 on the carrier plate 11 and the workstation plate 21, thus improving the ease of operation.

[0029] It should be noted that, in addition to the above-mentioned structure, other structures can also be used to place and fix the conduit 6 on the carrier plate 11 and the work station plate 21. Since the related structures are diverse and relatively conventional in the mechanical field, this utility model does not impose any restrictions on them.

[0030] See appendix Figure 4 - Appendix Figure 5 The bottom of the material cart 1 is equipped with multiple casters 12; this design can improve the mobility of the material cart 1, so that workers can push the material cart 1 to move the position of multiple pipes 6.

[0031] See appendix Figure 4 - Appendix Figure 8 The types of material components 32 are diverse, and this utility model does not impose any restrictions on them. For ease of understanding, the following examples are given in this embodiment: Firstly, the material handling component 32 uses a gripper cylinder 320, and the connecting column 61 is correspondingly equipped with a clamping block 612. Under normal circumstances, the gripping end of the gripper cylinder 320 is in an open state. After the first driving unit 31 drives the gripper cylinder 320 to move down and approach the clamping block 612 located at the top of the hose, the gripping end of the gripper cylinder 320 is controlled to retract and clamp the clamping block 612. Then, the first driving unit 31 is activated to drive the gripper cylinder 320 to move up, so that the hose can be taken away. Similarly, the gripping end of the gripper cylinder 320 is controlled to release the clamping block 612, so that the conduit 6 can be placed. Therefore, the cooperation of the first driving unit 31 with the gripper cylinder 320 and the clamping block 612 can realize the picking and placing of the conduit 6.

[0032] Secondly, the material handling component 32 uses an electromagnet (not shown in the figure), and the connecting post 61 is equipped with a corresponding magnetic block (not shown in the figure). Under normal circumstances, the electromagnet is in a de-energized and non-magnetic state. After the first driving unit 31 drives the electromagnet to move down and approach the magnetic block located at the top of the hose, the electromagnet is powered to restore its magnetism and attract the magnetic block. Then, the first driving unit 31 is activated to drive the electromagnet to move up, and the hose can be removed. Similarly, de-energizing the electromagnet allows the conduit 6 to be placed. Therefore, the combined use of the first driving unit 31 with the electromagnet and the magnetic block can also realize the picking and placing of the conduit 6.

[0033] It should be noted that since both the gripper cylinder 320 and the electromagnet are existing products, and the structure of using the gripper cylinder 320 to hold the gripper block 612 and using the electromagnet to attract the magnetic block to complete the picking and placing of items is quite conventional in the mechanical field, such as conventional robotic arms, the specific working process will not be described in detail in this utility model.

[0034] See appendix Figure 4 - Appendix Figure 8 The first drive unit 31 includes an X-axis moving unit 311, a Y-axis moving unit 312 and a Z-axis moving unit 313. The X-axis moving unit 311 is mounted on the machine body 2 and drivenly connected to the Y-axis moving unit 312. The Y-axis moving unit 312 is drivenly connected to the Z-axis moving unit 313, and the Z-axis moving unit 313 is drivenly connected to the material picking component 32.

[0035] Specifically, the Z-axis moving unit 313 can drive the picking member 32 to move up and down along the Z-axis to clamp / adsorb the connecting post 61, thereby facilitating the picking and placing of the guide tube 6. The X-axis moving unit 311 and the Y-axis moving unit 312 can drive the picking member 32 to move along the X-axis and Y-axis respectively, so that the picking member 32 can move along the movable groove 110 to align the connecting posts 61 on each guide tube 6 one by one, and facilitate the transfer of the guide tube 6 between the carrier plate 11 and the station plate 21.

[0036] It should be noted that the X-axis moving unit 311, Y-axis moving unit 312, and Z-axis moving unit 313 can adopt long-stroke structures such as linear guide modules and rack and pinion guide modules, or short-stroke structures such as lead screw motors and cylinders. Since the relevant structures are diverse and relatively conventional in the mechanical field, they belong to existing structures. Therefore, the specific types and structures are not described or limited in detail in this utility model.

[0037] See appendix Figure 1 Appendix Figure 2 Appendix Figure 9 and attached Figure 10The second drive unit 41 includes a lifting unit 411 and a fixed base 412. The cleaning component 42 is mounted on the fixed base 412. The lifting unit 411 is installed inside the body 2 and is drivenly connected to the fixed base 412.

[0038] Specifically, when the cleaning component 42 drives the wiping cloth 43 to abut the top of the conduit 6 located at the workstation plate 21, the lifting unit 411 drives the fixed seat 412 and the cleaning component 42 to move down along the Z-axis, so that the wiping cloth 43 can rub the outer wall of the conduit 6 from top to bottom to complete the cleaning operation; after cleaning, the cleaning component 42 first drives the wiping cloth 43 away from the conduit 6, and then the lifting unit 411 drives the fixed seat 412 and the cleaning component 42 to move up along the Z-axis to reset.

[0039] See appendix Figure 9 - Appendix Figure 18 The cleaning assembly 42 includes a guide plate 421, a pre-tensioning component 422, a parallel cylinder 423, and a first cylinder 424. A guide roller 4210, a first guide block 4211, and a second guide block 4212 are arranged in a triangular shape on the guide plate 421. The pre-tensioning component 422 includes a rotating rod 4221, a swing arm 4222, a shaft roller 4223, and a spring 4224. The rotating rod 4221 is mounted on a fixed base 412 and rotatably connected to the swing arm 4222. The shaft roller 4223 is rotatably mounted on the swing arm 4222. The two ends of the spring 4224 are respectively connected to the rotating rod 4221 and the swing arm 4222. Two pre-tensioning components 422 are provided and located on opposite sides of the guide plate 421. A first rotating column 4121 and a second rotating column 4122 located beside the shaft roller 4223 are also mounted on the fixed base 412. A wiping cloth 43 is wrapped around the first rotating column 4121, the first guide block 4211, and the first guide block 4212. The first cylinder 4210 is mounted on the roller 4210, the second guide block 4212, and the second rotating column 4122, and the two ends of the wiping cloth 43 are respectively connected to the two shaft rollers 4223; the parallel cylinder 423 is mounted on the guide plate 421, and the two output ends of the parallel cylinder 423 are each equipped with a support arm 4231 with a notch 4232, and the two notches 4232 together form a cleaning groove 4230; the guide roller 4210 is placed between the two support arms 4231 so that the wiping cloth 43 covers the two notches 4232; the guide plate 421 is slidably mounted on the fixed seat 412, and the first cylinder 424 is mounted on the fixed seat 412 and drivenly connected to the guide plate 421 to drive the guide plate 421 to move along the X-axis so that the guide tube 6 enters the cleaning groove 4230; the parallel cylinder 423 can drive the two support arms 4231 to move closer to each other so that the outer wall of the guide tube 6 enters the two notches 4232 and abuts against the wiping cloth 43.

[0040] Specifically, under normal circumstances, the guide plate 421 is away from the workstation plate 21, the two arms 4231 of the parallel cylinder 423 are far apart, the wiping cloth 43 is pulled taut by the two rollers 4223, and neither spring 4224 deforms; when the first cylinder 424 drives the guide plate 421 to move outward along the X-axis and approach the guide tube 6 on the workstation plate 21, the wiping cloth 43 is pulled and causes the two swing arms 4222 to swing, so that the two springs 4224 undergo adaptive deformation; while when the parallel cylinder When the two clamping arms are driven to come together to clamp the conduit 6, the wiping cloth 43 is pulled again to continue to drive the two swing arms 4222 to swing, which in turn causes the two springs 4224 to continue to deform and store energy. The deformed springs 4224 can provide pre-tight force to the wiping cloth 43 so that the wiping cloth 43 can fit tightly against the outer wall of the conduit 6. At this time, the lifting unit 411 is activated to drive the fixed seat 412 to move down along the Z-axis, so that the wiping cloth 43 can wipe the outer wall of the conduit 6 from top to bottom for cleaning.

[0041] After cleaning, the parallel cylinder 423 and the first cylinder 424 are activated in sequence to drive the two clamping arms away from each other and release the guide tube 6. The guide plate 421 moves inward along the X-axis away from the guide tube 6. During this process, the wiping cloth 43 is loosened, and the two springs 4224 will release energy and restore their original state, driving the two swing arms 4222 to swing back to their original state. The two rollers 4223 pull the wiping cloth 43 tight, ensuring that the wiping cloth 43 always remains taut. While the material picker 32 is taking away the cleaned guide tube 6, the lifting unit 411 will also drive the fixed seat 412 to move upward along the Z-axis, so that the cleaning component 42 is aligned with the top of the guide tube 6 to be cleaned again.

[0042] Therefore, the above structural design allows the wiping cloth 43 to remain taut throughout the entire operation, ensuring that the wiping cloth 43 fits tightly against the outer wall of the conduit 6 and thus guaranteeing the cleaning effect.

[0043] See appendix Figure 11 - Appendix Figure 18 In the above structure, since the part of the wiping cloth 43 that contacts the conduit 6 remains unchanged, the wiping cloth 43 is easily contaminated and cannot be used normally after wiping multiple conduits 6 or wiping a dirty conduit 6. This causes the staff to frequently replace the wiping cloth 43 manually, which is cumbersome and requires machine shutdown, affecting work efficiency. To solve this problem, in this utility model, the cleaning component 42 also includes a feeding wheel 425, a winding wheel 426, a damper 427, and a first motor 428. The feeding wheel 425 and the winding wheel 426 are rotatably mounted on the fixed base 412 and are located on both sides of the guide plate 421, respectively. The damper 427 is mounted on the fixed base 412 and is linked to the feeding wheel 425 to provide rotational damping. The first motor 428 is mounted on the fixed base 412 and is driven by the winding wheel 426. The first end of the wiping cloth 43 is wound to form a cloth roll 430, which is fixedly mounted on the feeding wheel 425, and the tail end of the wiping cloth is fixedly connected to the winding wheel 426.

[0044] Specifically, when the wiping cloth 43 is in a taut state, the first motor 428 drives the winding wheel 426 to stop, while the damper 427 provides sufficient damping to the unloading wheel 425 to fix the beginning and end of the wiping cloth 43. After the guide tube 6 is cleaned and the parallel cylinder 423 and the first cylinder 424 drive the two clamping arms to loosen and move away from the guide tube 6, causing the wiping cloth 43 to loosen, the first motor 428 is started to drive the winding wheel 426 to rotate and wind up the old wiping cloth 43. During this process, the tension provided by the first motor 428 to the wiping cloth 43 will overcome the tension provided by the damper 427 to the unloading wheel 425. The damping force provided drives the feed roller 425 to rotate so that the cloth roll 430 provides a new wiping cloth 43. After the new wiping cloth 43 is provided, the first motor 428 controls the feed roller 426 to stop, so that the damper 427 re-tightens the feed roller 425. The two springs 4224 will release energy and restore, driving the two swing arms 4222 to swing back to their original position, so as to tighten the wiping cloth 43 with the help of the two shaft rollers 4223, so as to facilitate the continuation of cleaning operations. Therefore, the above structural design can realize the automatic replacement of the wiping cloth 43 without stopping the machine, which significantly improves work efficiency and user experience.

[0045] It should be noted that the first motor 428 drives the winding wheel 426 to wind up the old wiping cloth 43, and the feeding wheel 425 rotates to provide the new wiping cloth 43 to the cloth roll 430, all of which are completed instantaneously and are not affected by the two springs 4224. Furthermore, the elastic potential energy of the two springs 4224 must be less than the rotational damping provided by the damper 427 to the feeding wheel 425, so as to prevent the two rollers 4223 from pulling the wiping cloth 43 and causing the feeding wheel 425 to loosen.

[0046] See appendix Figure 14 - Appendix Figure 18 The support arm 4231 also has multiple spring needles 4233 installed in the recess 4232, and the telescopic ends of the multiple spring needles 4233 correspond to multiple parts of the wiping cloth 43.

[0047] Specifically, when the outer wall of the conduit 6 enters the two recesses 4232, the wiping cloth 43 squeezes the telescopic end of the spring needle 4233, causing the corresponding spring needle 4233 to deform and store energy. The deformed spring needle 4233 has elastic potential energy, so it can continuously apply pressure to the corresponding position of the wiping cloth 43, so that the corresponding position of the wiping cloth 43 can continuously abut against the outer wall of the conduit 6. Moreover, since the positions of each spring needle 4233 corresponding to the outer wall of the conduit 6 are different, the shape of the wiping cloth 43 can also be kept consistent with the shape of the outer wall of the conduit 6. Under this structural design, the wiping cloth 43 can continuously and tightly fit the circumferential outer wall of the conduit 6, thereby ensuring a cleaner and more thorough wiping, significantly improving the cleaning effect. The spring needle 4233 is an existing product, so its specific structure will not be described in detail in this utility model.

[0048] See appendix Figure 14 - Appendix Figure 18 The cleaning component 42 also includes cotton blocks 429. Two cotton blocks 429 are provided and installed in two recesses 4232 respectively. The telescopic ends of multiple spring needles are inserted into the cotton blocks 429. The support arm 4231 is also provided with an injection hole 4234 that connects to the recesses 4232. Cleaning fluid can be added to the cotton blocks 429 located in the recesses 4232 through the injection hole 4234.

[0049] Specifically, before use, workers can add cleaning fluid to the cotton block 429 located in the recess 4232 through the injection hole 4234. When the outer wall of the conduit 6 enters the two recesses 4232, it will squeeze the cotton block 429 through the wiping cloth 43. After being squeezed, the cotton block 429 will provide cleaning fluid to the wiping cloth 43. The wiping cloth 43 with cleaning fluid can not only wipe the outer wall of the conduit 6 more cleanly, further improving the cleaning effect, but also prevent rigid friction between the wiping cloth 43 and the conduit 6, reducing the possibility of scratches on the outer wall of the conduit 6.

[0050] Furthermore, to achieve automatic supply of cleaning fluid, in some embodiments, a water pump (not shown in the figure) and a water tank (not shown in the figure) for loading the cleaning fluid can be additionally provided. The cleaning fluid in the water tank is continuously or intermittently pumped to the injection hole 4234 by the water pump, so as to replenish the cleaning fluid to the cotton block 429 located in the notch 4232. In addition, the cleaning fluid can be a liquid such as alcohol. Since there are many types, this utility model does not limit the types.

[0051] See appendix Figure 9 - Appendix Figure 11 The second drive unit 41 also includes a translation unit 413. The workstation plate 21 is slidably connected to the machine body 2, and at least two guide tubes 6 can be placed on the workstation plate 21. The translation unit 413 is installed in the machine body 2 and driven to drive the workstation plate, so as to drive the workstation plate 21 to move along the Y-axis so that the two guide tubes 6 can correspond to the cleaning tank 4230 one by one.

[0052] Specifically, the workstation plate 21 can hold at least two conduits 6, which is equivalent to having at least two workstations. The design of the translation unit 413 can be used to switch workstations. In this way, while the cleaning component 42 is wiping one of the conduits 6, the other conduit 6 to be cleaned can be transferred to the workstation plate 21 for pre-storage by the first drive unit 31 and the material picker 32. When one of the conduits 6 is cleaned, the translation unit 413 drives the workstation plate 21 to move along the Y-axis so that the pre-storage conduit 6 is aligned with the cleaning component 42 to start the cleaning operation. The cleaned conduit 6 is offset from the cleaning component 42 so that it can be transferred back to the material cart 1 by the first drive unit 31 and the material picker 32. Therefore, the above structural design can make the loading and unloading of the conduits 6 simultaneous, ensuring that the cleaning component 42 does not need to stop and wait, making the whole cleaning process more continuous, and further improving work efficiency and user experience.

[0053] It should be noted that the translation unit 413 can adopt a long-stroke structure such as a linear guide module or a gear and rack guide module, or a short-stroke structure such as a screw motor or a cylinder. Since the relevant structures are diverse and relatively conventional in the mechanical field, they belong to existing structures. Therefore, the specific types and structures are not described or limited in detail in this utility model.

[0054] See appendix Figure 4 - Appendix Figure 7 The present invention also includes a locking mechanism 5, which is installed in the operating cavity 20 and includes a positioning block 51, a second motor 52, a stop bar 53, a second cylinder 54 and a locking pin 55. The second motor 52 is driven to the stop bar 53, and the second cylinder 54 is driven to the locking pin 55. The material cart 1 is provided with a locking hole 13.

[0055] Specifically, during use, the material cart 1 is moved into the operating chamber 20 and abuts against the positioning block 51 so that the locking hole 13 aligns with the locking post 55. At this time, the second motor 52 is started to drive the stop bar to swing and abut against the inner wall of the material cart 1, and the second cylinder 54 is started to drive the locking post 55 to move and insert into the locking hole 13, thus locking the material cart 1 in the operating chamber 20, preventing the material cart 1 from moving and affecting the placement and removal of the guide tube 6; thus improving the stability of use.

[0056] It should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Any modifications, equivalent substitutions and improvements made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
