Description

Technical Field

[0001] This utility model relates to the field of automobile manufacturing technology, and in particular to a cleaning device for a glue application system. Background Technology

[0002] Automotive adhesives are an indispensable material in the automobile manufacturing and assembly process, playing an irreplaceable role in key aspects such as body structure splicing, battery pack encapsulation, and powertrain system integration.

[0003] In actual production, a glue application system is required. This system typically includes a relay tank, glue supply lines, a glue pump, and a glue gun. The relay tank stores the glue, the glue supply line connects to the glue gun, and the glue pump draws the glue from the relay tank. The glue flows through the supply line to the glue gun, and then the glue gun can be used to apply glue to areas such as body panel joints and door edges. As automakers place increasingly higher demands on the quality of automotive adhesives, such as durability, reliability, and safety, they are changing adhesives more frequently. When switching products, the entire glue application system needs thorough cleaning. However, due to the high viscosity and adhesion of the glue, it easily remains in the system, forming difficult-to-remove residues and waste glue. Therefore, a cleaning device equipped with a specialized cleaning solution is required to clean the entire glue application system.

[0004] Existing car manufacturers typically fill the cleaning tank with cleaning fluid first. Then, with the cleaning tank and cleaning gun connected, they open the cleaning gun to clean the intermediate tank and use a container to collect the cleaning fluid at the caulking gun. Once all the cleaning fluid in the cleaning tank is used up, the cleaning fluid in the container is poured back into the cleaning tank for the next cleaning cycle. However, using existing cleaning devices requires collecting enough cleaning fluid before proceeding to the next round of cleaning, resulting in low cleaning efficiency and a long overall cleaning cycle. Utility Model Content

One end of the adjusting screw is connected to the movable foot, and the other end of the adjusting screw is rotatably connected to the fixed foot. The rotation of the adjusting screw causes the movable foot to move closer to and away from the fixed foot, so that the fixed foot and the movable foot clamp the wall of the cleaning tank and slide in connection with the wall of the cleaning tank respectively.

[0025] Compared with the prior art, the embodiments of this utility model have the following beneficial effects:

[0026] 1. This cleaning device creates an additional cleaning fluid return path by setting up a return pipe and return pump connected to the glue application system. When cleaning, a portion of the cleaning fluid flowing out of the glue application system can enter the return pipe and return pump and return to the cleaning tank. This avoids the need to recover enough cleaning fluid before the next round of cleaning.

For example, "fixing" can mean a fixed connection, a detachable connection, or an integral part; it can mean a mechanical connection or an electrical connection; it can mean a direct connection or an indirect connection through an intermediate medium; it can mean the internal communication of two components or the interaction between two components, unless otherwise explicitly limited. Those skilled in the art can understand the specific meaning of the above terms in this utility model according to the specific circumstances.

[0039] Furthermore, in this utility model, descriptions involving "first," "second," etc., are for descriptive purposes only and should not be construed as indicating or implying their relative importance or implicitly specifying the number of technical features indicated. Therefore, features defined with "first" or "second" may explicitly or implicitly include at least one of those features. Additionally, the word "and / or" throughout the text means including three parallel solutions; taking "A and / or B" as an example, it includes solution A, solution B, or a solution that simultaneously satisfies A and B. Furthermore, the technical solutions of the various embodiments can be combined with each other, but this must be based on the ability of those skilled in the art to implement them. When the combination of technical solutions is contradictory or impossible to implement, it should be considered that such a combination of technical solutions does not exist and is not within the scope of protection claimed by this utility model.

[0040] This utility model proposes a cleaning device for a glue application system.

[0041] In the embodiments of this utility model, such as Figures 1 to 4 As shown, the cleaning device used in this glue application system includes:

[0042] Cleaning tank 1 is used to store cleaning fluid. Cleaning tank 1 has a liquid outlet and the top is open.

[0043] Cleaning pipe 2, the inlet end of cleaning pipe 2 is connected to the outlet end, and the outlet end of cleaning pipe 2 is connected to the cleaning gun.

[0044] The sliding bracket 3 is slidably disposed at the opening of the cleaning tank 1. The sliding bracket 3 includes a sliding part 31, a supporting part 32 and a clamping part 33; the sliding part 31 is slidably connected to the wall of the cleaning tank 1, and the supporting part 32 is connected to the sliding part 31 and the clamping part 33.

[0045] The return pipe 4 has its inlet end connected to the return end of the glue application system 7. The clamping part 33 clamps and fixes the outlet end of the return pipe 4. The cleaning liquid flowing out of the glue application system 7 flows back into the cleaning tank 1 through the return pipe 4.

[0046] Filter element 5 is installed inside the cleaning tank 1. The outlet end of the return pipe 4 is located above the filter element 5. The filter element 5 is used to filter the returned cleaning liquid.

[0047] Return pump 8 is installed on return pipe 4.

[0048] This cleaning device establishes an additional cleaning fluid return path by incorporating a return pipe 4 and a return pump 8 connected to the glue application system 7. During cleaning, a portion of the cleaning fluid flowing from the glue application system 7 enters the return pipe 4 and return pump 8 and flows back into the cleaning tank 1. This avoids the need to recover sufficient cleaning fluid before proceeding to the next cleaning cycle. This cleaning device enables automatic circulation of the cleaning fluid, effectively improving the recovery efficiency and providing sufficient cleaning fluid for the next cleaning cycle, thereby significantly improving cleaning efficiency and shortening the cleaning cycle. Furthermore, the device features a sliding bracket 3 at the opening of the cleaning tank 1. The clamping part 33 of the sliding bracket 3 can clamp and fix the outlet end of the return pipe 4. This eliminates the need for workers to hold the return pipe 4 for extended periods, greatly reducing labor intensity and effectively improving cleaning efficiency and shortening the cleaning cycle. In this cleaning device, the sliding bracket 3 is slidably mounted at the opening of the cleaning tank 1. Therefore, the installation position of the sliding bracket 3 can be adjusted according to the actual working environment, meeting the installation requirements of the actual working environment. This cleaning device has high applicability. This cleaning device uses a filter element 5 to filter the returned cleaning fluid, separating residual adhesive and waste adhesive from the cleaning fluid. This prevents the returned cleaning fluid from contaminating the cleaning fluid stored in the cleaning tank 1, maintaining a certain cleaning efficiency and cleaning capacity. Simultaneously, it prevents the accumulation of residual adhesive and waste adhesive in the cleaning tank 1, avoiding blockage of the outlet and ensuring the stable and efficient operation of this cleaning device. This invention solves the problems of low cleaning efficiency and long overall cleaning cycle associated with existing cleaning devices.

[0049] It should be noted that, as Figure 1 and 2 As shown, the glue application system 7 includes a relay tank 71, a glue supply pipeline 72, a glue supply pump 73, and a glue application gun (not shown in the figure). The glue supply pipeline 72 includes a first pipeline 721 and a second pipeline 722. The inlet end of the return pipe 4 is connected to the outlet end of the first pipeline 721. When cleaning the glue application system 7, a portion of the cleaning solution passes through the first pipeline 721 and the glue supply pump 73 into the return pipe 4 and the return pump 8, and then flows back to the cleaning tank 1. Therefore, using this cleaning device can achieve the purpose of cleaning the relay tank 71, the first pipeline 721, and the glue supply pump 73. A portion of the cleaning fluid enters the caulking gun through the first pipe 721, the glue supply pump 73, and the second pipe 722, thus achieving the purpose of cleaning the first pipe 721, the glue supply pump 73, the second pipe 722, and the caulking gun. At this time, the caulking gun is turned on to discharge the cleaning fluid, and the cleaning fluid discharged from the caulking gun is collected in a container and then poured into the cleaning tank 1 for reuse. Therefore, combined with this cleaning device, the entire caulking system 7 can be thoroughly cleaned.

[0050] To further explain, the outlet end of cleaning line 2 is connected to a cleaning gun (not shown in the figure). Turning on the cleaning gun allows for the cleaning of the relay tank 71.

[0051] To further explain, before cleaning, cleaning tank 1 contains unused cleaning fluid; after cleaning begins, cleaning tank 1 contains a mixture of unused cleaning fluid and recycled cleaning fluid; and in the later stages of cleaning, cleaning tank 1 contains recycled cleaning fluid.

[0052] Preferably, the liquid outlet is located at the bottom of the cleaning tank 1.

[0053] like Figure 1 , 3 As shown in Figure 4, in one embodiment of this application, the sliding part 31 includes a crossbeam 311, a fixed foot 312, a movable foot 313, and an adjusting screw 314;

[0054] The crossbeam 311 spans horizontally above the wall of the cleaning tank 1, and the crossbeam 311 is connected to the support part 32;

[0055] The fixed foot 312 is fixedly connected to the side of the crossbeam 311 near the central axis of the cleaning tank 1, and the movable foot 313 is slidably connected to the side of the crossbeam 311 away from the central axis of the cleaning tank 1. The shapes of the fixed foot 312 and the movable foot 313 are adapted to the shape of the tank wall of the cleaning tank 1.

[0056] The adjusting screw 314 is located between the crossbeam 311 and the cleaning tank 1, and the adjusting screw 314 and the crossbeam 311 are arranged parallel to each other. One end of the adjusting screw 314 is connected to a movable foot 313, and the other end of the adjusting screw 314 is rotatably connected to a fixed foot 312. The rotation of the adjusting screw 314 drives the movable foot 313 to move closer to and away from the fixed foot 312, so that the fixed foot 312 and the movable foot 313 clamp the wall of the cleaning tank 1 and slide in connection with the wall of the cleaning tank 1 respectively.

[0057] By setting up a crossbeam 311, a fixed foot 312, a movable foot 313, and an adjusting screw 314, the fixed foot 312 is fixedly connected to the side of the crossbeam 311 near the central axis of the cleaning tank 1, the movable foot 313 is slidably connected to the side of the crossbeam 311 away from the central axis of the cleaning tank 1, and one end of the adjusting screw 314 is connected to the movable foot 313, while the other end of the adjusting screw 314 is rotatably connected to the fixed foot 312. The rotation of the adjusting screw 314 causes the movable foot 313 to move closer to or away from the fixed foot 312. In this way, when the adjusting screw 314 is rotated, the adjusting screw 314 rotates and causes the movable foot 313 to move, thereby enabling the movable foot 313 to move towards or away from the fixed foot 312, that is, to adjust the distance between the fixed foot 312 and the movable foot 313. By clamping the fixed foot 312 and the movable foot 313 against the wall of the cleaning tank 1, stable support is provided for the entire sliding bracket 3 when they are clamped against the tank wall, ensuring that the sliding bracket 3 does not wobble or shift during sliding, thereby allowing the clamping part 33 to stably clamp the liquid outlet end of the return pipe 4. In addition, the adjustable distance between the fixed foot 312 and the movable foot 313 can adapt to cleaning tanks 1 with different wall thicknesses, improving the applicability of this cleaning device. By sliding the fixed foot 312 and the movable foot 313 to the wall of the cleaning tank 1 respectively, the position of the sliding part 31 is adjustable. Thus, when multiple sliding brackets 3 need to be installed, the position of the sliding brackets 3 can be flexibly adjusted according to the actual situation, ultimately achieving the fixation of multiple return pipes 4.

[0058] It should be noted that both the fixed foot 312 and the movable foot 313 extend along the depth direction of the cleaning tank 1. Preferably, the fixed foot 312 and the movable foot 313 are of the same length, which makes the clamping force of the fixed foot 312 and the movable foot 313 on the wall of the cleaning tank 1 more balanced, maintains uniform clamping on the tank wall, and avoids wobbling or displacement when the sliding bracket 3 slides, thereby ensuring that the liquid outlet end of the return pipe 4 is stably clamped and fixed.

[0059] In one embodiment of this utility model, the crossbeam 311 and the fixing foot 312 are integrally formed.

[0060] like Figure 1 , 3 As shown in Figure 4, in one embodiment of this application, the fixed foot 312 is provided with a plurality of sliding posts 315 on the side near the wall of the cleaning tank 1 and the movable foot 313 is provided with a plurality of sliding posts 315. The fixed foot 312 and the movable foot 313 are slidably connected to the wall of the cleaning tank 1 through the plurality of sliding posts 315.

[0061] By providing several sliding pillars 315 on the side of the fixed foot 312 near the wall of the cleaning tank 1 and the side of the movable foot 313 near the wall of the cleaning tank 1 respectively, the friction between the fixed foot 312 and the movable foot 313 and the wall of the cleaning tank 1 during the sliding process can be effectively reduced, thereby reducing the sliding friction of the entire sliding part 31 and achieving a smoother sliding effect for the sliding bracket 3.

[0062] In another embodiment of this utility model, the fixed foot 312 includes a first connecting post 3121 and a first bonding plate 3122. The two ends of the first connecting post 3121 along its own length direction (i.e., the depth direction of the cleaning tank 1) are respectively fixedly connected to the crossbeam 311 and the first bonding plate 3122. The first bonding plate 3122 protrudes from the first connecting post 3121 towards the wall of the cleaning tank 1. A plurality of sliding posts 315 are disposed on the side of the first bonding plate 3122 near the wall of the cleaning tank 1. The movable foot 313 includes a second connecting post 3131. The second bonding plate 3132 and the second connecting post 3131 are slidably connected at one end to the crossbeam 311 along their own length direction (i.e., the depth direction of the cleaning tank 1), and the other end is fixedly connected to the second bonding plate 3132. The second bonding plate 3132 protrudes from the second connecting post 3131 toward the wall of the cleaning tank 1. Several sliding posts 315 are arranged on the side of the second bonding plate 3132 near the wall of the cleaning tank 1. The first bonding plate 3122 and the second bonding plate 3132 clamp the wall of the cleaning tank 1 and are slidably connected to the wall of the cleaning tank 1 respectively.

[0063] Preferably, the cleaning box 1 has a cylindrical structure, and the shape of the box wall of the cleaning box 1 is arc-shaped. The first bonding plate 3122 is provided with a convex arc portion 3122a that matches the box wall of the cleaning box 1, and the second bonding plate 3132 is provided with a concave arc portion 3132a that matches the box wall of the cleaning box 1.

[0064] like Figure 3 and 4 As shown, in one embodiment of this application, the support portion 32 includes a first support member 321 and a second support member 322. The two ends of the first support member 321 are respectively connected to the crossbeam 311 and the second support member 322, and the end of the second support member 322 away from the first support member 321 is connected to the clamping portion 33.

[0065] The support part 32 serves as a connecting bridge between the sliding part 31 and the clamping part 33. When the sliding part 31 slides, the structure of the support part 32 can ensure that the clamping part 33 moves stably, preventing the return pipe 4 clamped and fixed by the clamping part 33 from shaking or shifting, thereby ensuring the stability and reliability of the operation of this cleaning device.

[0066] It should be noted that the dimensions and specifications of the first support member 321 and the second support member 322 can be the same or different, depending on the actual situation.

[0067] Optionally, both the first support member 321 and the second support member 322 are rod-shaped structures.

[0068] Optionally, the first support member 321 is vertically connected to the crossbeam 311 and extends along the direction away from the cleaning tank 1. The second support member 322 is vertically connected to the first support member 321 (i.e., the second support member 322 is horizontally arranged above the cleaning tank 1) and extends toward the central axis of the cleaning tank 1.

[0069] In one embodiment of this invention, multiple sliding supports 3 are installed on the wall of the cleaning tank 1. By installing multiple sliding supports 3 on the wall of the cleaning tank 1, multiple clamping parts 33 can simultaneously clamp and fix multiple return pipes 4. Furthermore, the position of the sliding parts 31 can be flexibly adjusted according to actual conditions to fix the multiple return pipes 4 and return the cleaning liquid flowing out of multiple glue application systems 7 back into the cleaning tank 1. This satisfies the need to clean multiple glue application systems 7 simultaneously, effectively improving cleaning efficiency, further shortening the overall cleaning cycle, and increasing production efficiency.

[0070] like Figures 1 to 3 As shown, in one embodiment of this application, the liquid outlet of the reflux pipe 4 is detachably connected to the clamping part 33. The clamping part 33 includes a first arc plate 331, a second arc plate 332 and a fastener 333. The first arc plate 331 is fixedly connected to the support part 32, and the second arc plate 332 is connected to the first arc plate 331 through the fastener 333. The liquid outlet of the reflux pipe 4 is clamped between the first arc plate 331 and the second arc plate 332.

[0071] The clamping part 33 clamps and fixes the liquid outlet end of the return pipe 4. By setting the first arc plate 331, the second arc plate 332 and the fastener 333, the entire clamping part 33 can stably clamp the liquid outlet end of the return pipe 4. This not only ensures that the return pipe 4 remains stable when it encounters the sliding part 31, preventing it from shaking or shifting, but also further improves the stability and reliability of the operation of this cleaning device, ensuring that the cleaning liquid flowing out from the glue application system 7 flows back into the cleaning tank 1 through the return pipe 4.

[0072] Preferably, the clamping part 33 is a clamp structure.

[0073] like Figure 3 and 5 As shown, in one embodiment of this application, the fastener 333 includes a plurality of bolts, the first arc plate 331 is provided with a plurality of first threaded holes through it along its own thickness direction, the second arc plate 332 is provided with a second threaded hole through it along its own thickness direction corresponding to the plurality of first threaded holes, and the bolts are threadedly connected to the first threaded holes and the second threaded holes.

[0074] Fastener 333 includes several bolts, which allow the second arc plate 332 to be pre-connected to the first arc plate 331, creating a gap between the first arc plate 331 and the second arc plate 332 for the return pipe 4 to pass through. Once the outlet position of the return pipe 4 is determined, simply rotating the bolts clamps and secures the outlet end of the return pipe 4. After cleaning, simply rotating the bolts in the opposite direction increases the gap between the first arc plate 331 and the second arc plate 332, allowing the return pipe 4 to be quickly removed. When reinstalling the return pipe 4, it can be placed between the first arc plate 331 and the second arc plate 332, making installation convenient. Therefore, using bolts facilitates the installation and removal of the return pipe 4, effectively improving its efficiency and thus enhancing the cleaning efficiency of the adhesive application system 7.

[0075] like Figure 1 As shown, in one embodiment of this application, the filter element 5 is a filter screen, the filter element 5 is connected to the inner wall of the cleaning tank 1, and the shape of the filter element 5 is adapted to the shape of the inner wall of the cleaning tank 1.

[0076] The filter element 5 is a filter screen, and its shape is adapted to the shape of the inner wall of the cleaning tank 1. In this way, different mesh sizes of filter elements 5 can be selected according to actual needs, which can efficiently separate residual adhesive and waste adhesive from the cleaning liquid. Moreover, the filter element 5 can be reused after cleaning, which has the advantages of low cost and green environmental protection, and is suitable for large-scale application.

[0077] To further explain, the filter element 5 divides the interior of the cleaning tank 1 into two interconnected spaces, one above the other.

[0078] It should be noted that the embodiments of this utility model only require that the filter element 5 be stably installed inside the cleaning tank 1, and the internal structure of the cleaning tank 1 is not limited. For example, the filter element 5 can be stably installed by setting several convex structures such as ridges and blocks on the inner wall of the cleaning tank 1.

[0079] Preferably, the filter element 5 is detachably connected to the inner wall of the cleaning tank 1. In this way, when maintenance is required on the cleaning tank 1 or the filter element 5, it is only necessary to remove the filter element 5 from the cleaning tank 1, which greatly improves maintenance efficiency.

[0080] Optionally, the filter element 5 has a mesh size of 80.

[0081] like Figure 1 and 2As shown, in one embodiment of this application, the cleaning box 1 includes a box body 11, support legs 12 and pulleys 13; the box body 11 is hollow inside and has a liquid outlet at the bottom, and the box body 11 has a funnel-shaped structure; a number of support legs 12 are symmetrically arranged at the bottom of the box body 11, and a number of pulleys 13 are arranged at the ends of the support legs 12 away from the box body 11.

[0082] The housing 11 has a funnel-shaped structure (i.e., a combination of cylindrical and conical shapes), which can accelerate the flow rate of the cleaning fluid and facilitate the rapid entry of the cleaning fluid from the outlet into the cleaning pipeline 2. The support legs 12 provide support for the housing 11. The pulleys 13 allow the cleaning tank 1 to be moved simply by applying external force, eliminating the need for manual handling. This not only effectively reduces labor intensity but also significantly shortens the moving time of the cleaning tank 1, improving overall work efficiency.

[0083] Preferably, the pulley 13 is a caster wheel. By using caster wheels, the cleaning tank 1 can move freely and flexibly in multiple directions.

[0084] like Figure 1 and 2 As shown, in one embodiment of this application, the cleaning pipeline 2 includes a first cleaning pipe 21, a cleaning pump 22, and a second cleaning pipe 23; the inlet end of the first cleaning pipe 21 is connected to the outlet end, and the input end and output end of the cleaning pump 22 are respectively connected to the outlet end of the first cleaning pipe 21 and the inlet end of the second cleaning pipe 23.

[0085] It should be noted that the outlet end of the second cleaning pipe 23 is connected to the cleaning gun (not shown in the figure). After the first cleaning pipe 21 delivers the cleaning fluid to the cleaning pump 22, the cleaning pump 22 provides power to the cleaning fluid and adjusts the pressure according to the actual cleaning needs, causing the pressure of the cleaning fluid to change. The treated cleaning fluid flows through the second cleaning pipe 23 into the cleaning gun. Turning on the cleaning gun allows for cleaning of the adhesive application system 7, effectively improving the cleaning effect of this cleaning device and giving the entire cleaning pipeline 2 high stability, thereby ensuring the stability of the cleaning device in use.

[0086] Preferably, the cleaning pump 22 is a high-pressure pump, and the cleaning gun is a high-pressure gun.

[0087] like Figure 1 and 2 As shown, in one embodiment of this application, the cleaning device further includes a first valve and a second valve 6; the liquid outlet is connected to the liquid inlet of the first cleaning pipe 21 through the first valve, and the second valve 6 is installed on the first cleaning pipe 21.

[0088] The first valve (not shown in the figure) is used to control the opening and closing of the liquid outlet, which can control the timing of the cleaning fluid flow. In case of abnormality, the first valve can be quickly closed to prevent the accident from escalating. The second valve 6 is installed on the first cleaning pipe 21 and can be used to control the liquid flow rate and hydraulic pressure in the first cleaning pipe 21. It plays a protective role for the first cleaning pipe 21, ensuring the stability and reliability of the operation of this cleaning device and further extending the service life of this cleaning device.

[0089] In another embodiment of this utility model, a third valve (not shown in the figure) is installed on the second pipe 722 of the glue supply pipe 72. When the glue gun discharges clean cleaning liquid, it means that the glue gun has been cleaned. At this time, the third valve can be closed, and the return pipe 4 and the return pump 8 can be used to continue cleaning the relay tank 71, the first pipe 721 and the glue supply pump 73.

[0090] The installation and usage process of one embodiment of this utility model is as follows:

[0091] Installation process: First, install the sliding bracket 3 onto the wall of the cleaning tank 1. Then, use the clamping part 33 to clamp and fix the liquid outlet end of the return pipe 4, and install the return pump 8 onto the return pipe 4 to ensure that the cleaning liquid flowing out from the glue application system 7 can flow back into the cleaning tank 1 through the return pipe 4 and the return pump 8. Next, connect and install the first cleaning pipe 21, the cleaning pump 22, the second cleaning pipe 23, and the cleaning gun (not shown in the figure).

[0092] Operating Procedure: Open the first valve, the valve at the bottom of the relay tank 71, the second valve 6, and the third valve. Then, turn on the cleaning pump 22 and the return pump 8. Once the pressure of the cleaning pump 22 and the return pump 8 stabilizes, adjust the nozzle of the cleaning gun to begin cleaning the relay tank 71. The cleaning solution flows out from the outlet. At this time, a portion of the cleaning solution passes through the first pipeline 721 and the glue supply pump 73 into the return pipe 4 and the return pump 8, and flows back into the cleaning tank 1. Another portion of the cleaning solution passes through the first pipeline 721, the glue supply pump 73, and the second pipeline 722 into the glue gun. Turn on the glue gun to discharge the cleaning solution, and pour the collected cleaning solution into the cleaning tank 1 for reuse. When the glue gun discharges clean cleaning solution, close the third valve and continue cleaning the relay tank 71, the first pipeline 721, and the glue supply pump 73 using the return pipe 4 and the return pump 8. After the cleaning work is completed, turn off the cleaning pump 22, the return pump 8, and the first valve. Then, remove the return pipe 4 from the sliding bracket 3, remove the return pump 8 from the return pipe 4, and remove the cleaning pump 22 and the cleaning gun from the first cleaning pipe 21 and the second cleaning pipe 23. Finally, push the cleaning tank 1 to the designated waste liquid discharge position and discharge the cleaning liquid in the cleaning tank 1 for unified treatment.

[0093] The technical principles of this utility model have been described above with reference to specific embodiments. These descriptions are merely for explaining the principles of this utility model and should not be construed as limiting the scope of protection of this utility model in any way. Based on this explanation, those skilled in the art can readily conceive of other specific embodiments of this utility model without any inventive effort, and these embodiments will all fall within the scope of protection of this utility model.
