Description

Technical Field

[0001] This utility model relates to the field of cleaning tools, and more specifically, to a flexible pipe degreasing cleaner. Background Technology

[0002] Soft melamine foam, also known as melamine sponge, has a porous three-dimensional network structure with open-cell pores, boasting an open-cell rate of over 90%. It absorbs dirt from the surface of objects during wiping and is used as a cleaning wipe with good cleaning effect.

[0003] However, when encountering stains that are difficult to dissolve in water, such as oil stains, the cleaning effect of melamine foam alone is not ideal. It is necessary to first spray organic solvents such as ethanol on the oil stains, and then use melamine foam to wipe the surface to achieve the desired cleaning effect.

[0004] At the same time, because soft melamine foam is relatively soft, when encountering some narrow and slender cleaning areas, such as tubes with small inner diameters, directly cut pieces of soft melamine foam are difficult to reach the cleaning area and are difficult to form effective friction with the area being cleaned. Utility Model Content

[0005] The present invention aims to provide a flexible pipe degreasing cleaner to solve the problems of poor cleaning effect of melamine foam in narrow areas and inconvenience of using it with organic solvents in the prior art.

[0006] The embodiments of this utility model are implemented as follows: This utility model provides a flexible pipe degreasing cleaner, which includes a flexible central support; The aforementioned central support is equipped with several spaced-apart cleaning units; Several of the above-mentioned cleaning units each have a water-soluble film, a first soft melamine foam layer in a compressed state, a second soft melamine foam layer in a compressed state, and several organic solvents; The water-soluble film is sleeved on the outer surface of the second soft melamine foam layer, the first soft melamine foam layer is sleeved on the central support, the outer surface of a plurality of organic solvents has a plastic film, and the plurality of organic solvents are evenly distributed in the gap between the first soft melamine foam layer and the second soft melamine foam layer. The aforementioned central support sequentially penetrates the aforementioned first soft melamine foam layer of several of the aforementioned cleaning units; Each of the aforementioned cleaning units has a fixing clamp at both ends, and the fixing clamp is securely connected to the aforementioned central support.

[0007] In use, first, according to the length of the pipe to be cleaned, cut a cleaning unit of the corresponding length, consisting of the water-soluble film, the first soft melamine foam layer, the second soft melamine foam layer, the plastic film, and the organic solvent. Then, press the cleaning unit with a little force to break the plastic film encapsulating the organic solvent, allowing the organic solvent to evenly penetrate into the first and second soft melamine foam layers. Next, wet the cleaner with water. Before the water-soluble film dissolves, insert the cleaner into the pipe. At this time, the first and second soft melamine foam layers rebound and the second soft melamine foam layer adheres to the inner wall of the pipe. Finally, pull the central support, and the degreasing operation is completed through the friction between the second soft melamine foam layer and the inner wall of the pipe.

[0008] This embodiment discloses a flexible pipe degreasing cleaner. Using the aforementioned central support as its core, it incorporates a cleaning unit composed of a water-soluble film, a first soft melamine foam layer, a second soft melamine foam layer, a plastic film, and an organic solvent. The cleaning unit is stably assembled via a fixing clamp. This design allows the flexible metal central support to adapt to complex pipe environments such as curved pipes, while the water-soluble film's compression of the foam layers ensures the cleaner can easily penetrate narrow pipes. Simultaneously, the organic solvent sealed within the plastic film precisely penetrates both foam layers during use. Combined with the foam layers' rebound and close friction against the pipe's inner wall, this efficiently combines physical and chemical degreasing capabilities. This effectively solves the problems of inconvenience and poor individual cleaning effect of existing blocky melamine foam, resulting in a flexible and efficient pipe degreasing cleaner that effectively cleans oil stains from pipe inner walls.

[0009] As a preferred embodiment of the present invention: both the first soft melamine foam layer and the second soft melamine foam layer are ring structures, and there is a solvent gap between the first soft melamine foam layer and the second soft melamine foam layer, with a plurality of organic solvents uniformly distributed in the solvent gap.

[0010] This design allows the annular structure to be fitted with the central support for through-installation, while also forming a more closely fitting annular contact surface with the inner wall of the pipe, improving the uniformity of physical friction cleaning. In addition, the solvent gap provides a stable storage space for the organic solvent, allowing the uniformly distributed organic solvent to quickly and evenly penetrate into the first and second soft melamine foam layers after the plastic film breaks. This avoids differences in cleaning effect caused by local accumulation or uneven distribution of the organic solvent, ensuring that each area of ​​the second soft melamine foam layer has sufficient chemical degreasing ability, further improving the efficiency of cleaning oil stains on the inner wall of the pipe and the overall cleaning effect.

[0011] As a preferred embodiment of this utility model, the two ends of the water-soluble film are tightly installed on the central support by the fixing clamps.

[0012] This configuration, through the binding force of the aforementioned fixed clamp, ensures that the water-soluble film forms a stable and uniform compression state on the first and second soft melamine foam layers it encases. This prevents the foam layers from prematurely rebounding and increasing in diameter due to loosening of the water-soluble film when the cleaner is not in use (e.g., during storage or insertion into the pipe), thus ensuring that the cleaner can smoothly enter narrow pipe spaces. Furthermore, it strengthens the connection stability between the water-soluble film and the central support, preventing relative displacement or detachment of the water-soluble film and the central support when the cleaner is moved back and forth within the pipe. This ensures that the subsequent processes of the water-soluble film dissolving in water and the second soft melamine foam layer precisely rebounding and adhering to the inner wall of the pipe proceed in an orderly manner, further guaranteeing the reliability and effectiveness of the cleaning operation.

[0013] As a preferred embodiment of this utility model: the natural thickness of the first soft melamine foam layer and the second soft melamine foam layer is 5mm to 100mm, and the thickness of the first soft melamine foam layer and the second soft melamine foam layer after compression by the water-soluble film is 2.5mm to 50mm.

[0014] This design significantly reduces the overall diameter of the cleaner after compression, ensuring it can easily penetrate narrow pipe spaces with smaller inner diameters, solving the problem of blocky foam being unable to reach confined cleaning areas. Furthermore, the natural thickness of 5mm to 100mm provides ample rebound margin for both the first and second soft melamine foam layers. After the water-soluble film dissolves in water, both layers can fully rebound to near their natural thickness, allowing the outer wall of the second soft melamine foam layer to tightly adhere to the inner wall of the pipe and create effective friction. Combined with the penetrating organic solvent, this ensures both the adhesion of physical cleaning and the full utilization of chemical degreasing properties, ultimately improving the effectiveness and compatibility of cleaning oil stains on the inner wall of the pipe.

[0015] As a preferred embodiment of this utility model, the above-mentioned water-soluble film is a polyvinyl alcohol water-soluble film or a water-soluble polyimide film.

[0016] This design ensures that both the polyvinyl alcohol water-soluble film and the water-soluble polyimide film possess excellent water solubility, dissolving quickly and completely upon contact with water without leaving any impurities that could affect the cleaning effect. It also ensures that the compressed first and second soft melamine foam layers rebound smoothly, allowing the outer wall of the second soft melamine foam layer to adhere to the inner wall of the pipe. Furthermore, the first and second soft melamine foam layers also possess good flexibility and tensile strength. During the compression and wrapping of the foam layers, and the insertion and retraction of the cleaner into the pipe, film damage can be prevented, avoiding premature rebound of the foam layers or leakage of the organic solvents. This guarantees the structural stability of the cleaner before use and its operational reliability during use, further adapting to the cleaning needs of removing oil stains from pipes.

[0017] As a preferred embodiment of this utility model, the thickness of the above-mentioned water-soluble film is 0.03mm to 0.07mm.

[0018] This design ensures that the water-soluble film within this thickness range possesses sufficient flexibility and tensile strength. It maintains structural integrity when compressing and wrapping the first and second soft melamine foam layers, preventing premature foam layer rebound due to excessive thinness during the cleaner's storage or insertion into the pipe. Conversely, excessive thickness does not compromise the overall flexibility of the cleaner. Furthermore, the 0.03mm to 0.07mm thickness ensures rapid dissolution of the water-soluble film upon contact with water, preventing slow dissolution from hindering the timely rebound and adhesion of the second soft melamine foam layer to the pipe's inner wall. It also avoids residual impurities after dissolution due to insufficient thickness, balancing structural stability before use with dissolution efficiency during use, thus guaranteeing smooth operation and effective cleaning of the pipes.

[0019] As a preferred embodiment of this utility model, the above-mentioned organic solvent is one or more of ethanol, acetone, and tetrahydrofuran.

[0020] With this configuration, these solvents possess excellent oil stain solubility, enabling them to quickly penetrate the first and second soft melamine foam layers and efficiently decompose oil stains on the inner wall of the pipe. This effectively compensates for the poor oil stain cleaning effect of physical cleaning with melamine foam alone. Furthermore, these solvents are chemically stable and their volatility and safety are suitable for pipe cleaning scenarios. They will not react adversely with melamine foam, the aforementioned water-soluble film, or other components. They also facilitate the full utilization of oil stain removal efficacy through friction during the cleaning process. In addition, multiple solvents can be flexibly combined to adapt to different types of pipe oil stains (such as stubborn oil stains and ordinary oil stains), further improving the cleaner's adaptability to different scenarios and its oil stain removal efficiency.

[0021] As a preferred embodiment of this utility model: the above-mentioned plastic film is a sealing film, and the above-mentioned organic solvent is sealed inside the above-mentioned plastic film.

[0022] This design provides reliable isolation and protection for the aforementioned organic solvents, preventing them from being lost due to leakage or evaporation during storage, transportation, or when the cleaner is not in use, or from prematurely contacting the first and second soft melamine foam layers, thus ensuring the effective content and activity of the solvents. In addition, the sealed structure allows for precise control of the release timing of the organic solvents. The plastic film is only broken when the cleaner is in use, ensuring that the organic solvents can concentrate and quickly penetrate into the foam layer. This avoids waste or unstable cleaning effects caused by premature action of the organic solvents, further improving the controllability of the cleaner and the reliability of degreasing.

[0023] As a preferred embodiment of this utility model: the above-mentioned central support is made of metal, and the diameter of the above-mentioned central support is 0.05mm to 0.5mm.

[0024] This design, using metal, provides the central support with excellent flexibility and structural strength. It allows the cleaner to bend freely to fit into complex pipe environments such as curved pipes, and it can withstand tension during cleaning without easily breaking, ensuring operational stability. In addition, the small diameter design of 0.05mm to 0.5mm ensures the supporting function of the central support while minimizing its impact on the overall size of the cleaner. This prevents the cleaner from being unable to fit into narrow pipes due to an excessively thick central support, and it does not interfere with the compression and rebound of the first and second soft melamine foam layers, thus balancing the cleaner's adaptability to different scenarios and its structural functionality.

[0025] As a preferred embodiment of this utility model, the length of the cleaner is 1m to 50m.

[0026] This design allows for flexible adaptation to the cleaning needs of pipes of different lengths, satisfying both short-distance, small-diameter pipes and long-distance pipes (such as industrial long-distance pipelines and household long drainage pipes). It eliminates the need for frequent splicing of the cleaner, improving operational convenience. Furthermore, the 1m-50m length design ensures a wide cleaning range while avoiding issues such as incomplete cleaning due to excessive length or the cleaner getting stuck and difficult to operate due to excessive length. This balances cleaning coverage with practicality, further expanding the range of applicable scenarios for the cleaner.

[0027] In summary, the flexible pipe degreasing cleaner disclosed in this utility model has the beneficial effect of flexibly and efficiently cleaning oil stains on the inner wall of pipes. Attached Figure Description

[0031] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this utility model, and not all embodiments. The components of the embodiments of this utility model described and shown in the accompanying drawings can generally be arranged and designed in various different configurations.

[0032] Therefore, the following detailed description of the embodiments of the present invention provided in the accompanying drawings is not intended to limit the scope of the claimed invention, but merely to illustrate selected embodiments of the invention. All other embodiments obtained by those skilled in the art based on the embodiments of the present invention without inventive effort are within the scope of protection of the present invention.

[0033] Example See Figure 1 , Figure 2 and Figure 3 This embodiment provides a flexible pipe degreasing cleaner, including a flexible central support 1; The central support 1 is equipped with several cleaning units 2 spaced apart; Each of the cleaning units 2 has a water-soluble film 3, a first soft melamine foam layer 4 under compression, a second soft melamine foam layer 5 under compression, and several organic solvents 6; A water-soluble film 3 is fitted on the outer surface of the second soft melamine foam layer 5, and the first soft melamine foam layer 4 is fitted on the central support 1. The outer surface of a number of organic solvents 6 has a plastic film 7, and the number of organic solvents 6 are evenly distributed in the gap between the first soft melamine foam layer 4 and the second soft melamine foam layer 5. The central support 1 passes through the first soft melamine foam layer 4 of several cleaning units 2 in sequence; Several cleaning units 2 are provided with fixed clamps 8 at both ends, and the fixed clamps 8 are securely connected to the central support 1.

[0034] In use, first, according to the length of the pipe to be cleaned, cut a cleaning unit 2 of the corresponding length, which consists of a water-soluble film 3, a first soft melamine foam layer 4, a second soft melamine foam layer 5, a plastic film 7, and an organic solvent 6. Then, press the cleaning unit 2 with a little force to break the plastic film 7 that encapsulates the organic solvent 6, allowing the organic solvent 6 to penetrate evenly into the first soft melamine foam layer 4 and the second soft melamine foam layer 5. Next, wet the cleaner with water. Before the water-soluble film 3 dissolves, insert the cleaner into the pipe. At this time, the first soft melamine foam layer 4 and the second soft melamine foam layer 5 rebound and the second soft melamine foam layer 5 adheres to the inner wall of the pipe. Finally, pull the central support 1, and the oil stain removal operation is completed by the friction between the second soft melamine foam layer 5 and the inner wall of the pipe.

[0035] This embodiment discloses a flexible pipe degreasing cleaner. It uses a central support 1 as its core support, combined with a cleaning unit 2 consisting of a water-soluble film 3, a first soft melamine foam layer 4, a second soft melamine foam layer 5, a plastic film 7, and an organic solvent 6. The cleaning unit 2 is stably assembled via a fixing clamp 8. This design allows the flexible metal central support 1 to adapt to complex pipe environments such as curved pipes, while the water-soluble film 3's compression of the foam layers ensures the cleaner can smoothly penetrate narrow pipes. Simultaneously, the organic solvent 6, sealed within the plastic film 7, can precisely penetrate both foam layers during use. Combined with the foam layers' rebound and close friction against the pipe's inner wall, this effectively combines physical and chemical degreasing capabilities, solving the problems of inconvenience and poor individual cleaning effect of existing blocky melamine foam. Therefore, this flexible pipe degreasing cleaner achieves the beneficial effect of flexible and efficient cleaning of oil stains on the inner walls of pipes.

[0036] See Figure 1 , Figure 2 and Figure 3 Both the first soft melamine foam layer 4 and the second soft melamine foam layer 5 have annular structures. There is a solvent gap 9 between the first soft melamine foam layer 4 and the second soft melamine foam layer 5. A number of organic solvents 6 are evenly distributed in the solvent gap 9. This annular structure can be adapted to the through installation of the central support 1, and at the same time, it forms a more closely fitting annular contact surface with the inner wall of the pipe, improving the uniformity of physical friction cleaning. In addition, the solvent gap 9 provides a stable storage space for the organic solvents 6. The evenly distributed organic solvents 6 can quickly and evenly penetrate into the first soft melamine foam layer 4 and the second soft melamine foam layer 5 after the plastic film 7 is broken. This avoids the difference in cleaning effect caused by local accumulation or uneven distribution of organic solvents 6, ensuring that each area of ​​the second soft melamine foam layer 5 has sufficient chemical degreasing ability, further improving the efficiency of cleaning oil stains on the inner wall of the pipe and the overall cleaning effect.

[0037] The two ends of the water-soluble film 3 are tightly installed on the central support 1 by fixing clamps 8. This ensures that the water-soluble film 3 forms a stable and uniform compression state with respect to the first soft melamine foam layer 4 and the second soft melamine foam layer 5 it wraps around, preventing the foam layer from prematurely rebounding and increasing in diameter due to loosening of the water-soluble film 3 when the cleaner is not in use (such as during storage or insertion into the pipe). This ensures that the cleaner can smoothly enter the narrow pipe space. In addition, it can enhance the connection stability between the water-soluble film 3 and the central support 1, preventing relative displacement or detachment of the water-soluble film 3 and the central support 1 when the cleaner is pulled back and forth in the pipe. This ensures that the subsequent process of the water-soluble film 3 dissolving in water and the second soft melamine foam layer 5 accurately rebounding and adhering to the inner wall of the pipe proceeds in an orderly manner, further guaranteeing the reliability and cleaning effect of the cleaning operation.

[0038] See Figure 1 , Figure 2 and Figure 3 The natural thickness of the first soft melamine foam layer 4 and the second soft melamine foam layer 5 are both 5mm to 100mm. After being compressed by the water-soluble film 3, the thickness of both layers is 2.5mm to 50mm. This compressed thickness significantly reduces the overall diameter of the cleaner, ensuring it can easily penetrate narrow pipes with smaller inner diameters, solving the problem of blocky foam struggling to reach confined cleaning areas. Furthermore, the natural thickness of 5mm to 100mm is the first soft... The first soft melamine foam layer 4 and the second soft melamine foam layer 5 have sufficient rebound margin. After the water-soluble film 3 dissolves in water, the first soft melamine foam layer 4 and the second soft melamine foam layer 5 can fully rebound to a thickness close to their natural thickness. This allows the outer wall of the second soft melamine foam layer 5 to tightly adhere to the inner wall of the pipe and form effective friction. Combined with the penetrating organic solvent 6, it can ensure the adhesion of physical cleaning and give full play to the chemical degreasing effect, ultimately improving the effectiveness and adaptability of cleaning oil stains on the inner wall of the pipe.

[0039] The water-soluble film 3 is either a polyvinyl alcohol water-soluble film 3 or a water-soluble polyimide film. Both the polyvinyl alcohol water-soluble film 3 and the water-soluble polyimide film have excellent water solubility. They can dissolve quickly and completely when exposed to water, without leaving any impurities that would affect the cleaning effect. This ensures that the compressed first soft melamine foam layer 4 and the second soft melamine foam layer 5 can rebound smoothly and that the outer wall of the second soft melamine foam layer 5 can adhere to the inner wall of the pipe. In addition, the first soft melamine foam layer 4 and the second soft melamine foam layer 5 also have good flexibility and tensile strength. During the compression and wrapping of the foam layers and the insertion and pulling of the cleaner into the pipe, the film can be prevented from breaking, which would cause the foam layers to rebound prematurely or the organic solvent 6 to leak. This ensures the structural stability of the cleaner before use and the operational reliability during use, further adapting to the cleaning needs of pipe degreasing scenarios.

[0040] See Figure 1 , Figure 2 and Figure 3 The thickness of the water-soluble film 3 is 0.03mm to 0.07mm. This thickness range provides sufficient flexibility and tensile strength, ensuring structural integrity when compressing and wrapping the first soft melamine foam layer 4 and the second soft melamine foam layer 5. This prevents premature rebound of the foam layer due to excessively thin film during the storage or insertion of the cleaner into the pipe, while also preventing excessive thickness from affecting the overall flexibility of the cleaner. In addition, the thickness of 0.03mm to 0.07mm ensures that the water-soluble film 3 dissolves quickly upon contact with water, preventing slow dissolution from hindering the timely rebound and adhesion of the second soft melamine foam layer 5 to the inner wall of the pipe. It also avoids residual impurities after dissolution due to insufficient thickness, thus balancing the structural stability of the cleaner before use with the dissolution efficiency during use, ensuring smooth operation and effective cleaning of the pipe.

[0041] Organic solvent 6 is one or more of ethanol, acetone, and tetrahydrofuran. These solvents all have excellent oil stain solubility, can quickly penetrate the first soft melamine foam layer 4 and the second soft melamine foam layer 5 and efficiently decompose oil stains on the inner wall of the pipe, effectively making up for the problem that physical cleaning of oil stains by melamine foam alone is not effective. In addition, these solvents are chemically stable and their volatility and safety are suitable for pipe cleaning scenarios. They will not react adversely with melamine foam, water-soluble film 3 and other components, and can also fully exert their oil stain removal effect through friction during the cleaning process. At the same time, multiple solvents can be flexibly combined to adapt to different types of pipe oil stains (such as stubborn oil stains and ordinary oil stains), further improving the adaptability of the cleaner to different scenarios and the oil stain removal efficiency.

[0042] See Figure 1 , Figure 2 and Figure 3The plastic film 7 is a sealing film, and the organic solvent 6 is sealed inside the plastic film 7. This provides reliable isolation protection for the organic solvent 6, preventing the organic solvent 6 from being lost due to leakage or evaporation during storage, transportation, or when the cleaner is not in use, or from prematurely contacting the first soft melamine foam layer 4 and the second soft melamine foam layer 5, which would lead to a decrease in effectiveness. This ensures the effective content and activity of the solvent. In addition, the sealed structure can precisely control the release timing of the organic solvent 6. The plastic film 7 is only broken by pressing during use, ensuring that the organic solvent 6 can concentrate and quickly penetrate into the foam layer. This avoids waste caused by premature action of the organic solvent 6 or unstable cleaning effect, further improving the controllability of the cleaner and the reliability of degreasing.

[0043] The central support 1 is made of metal, and its diameter is 0.05mm to 0.5mm. The metal material gives the central support 1 excellent flexibility and structural strength, which can support the cleaner to bend freely to adapt to complex pipe scenarios such as bends, and can withstand the tension when cleaning back and forth without breaking, ensuring operational stability. In addition, the small diameter design of 0.05mm to 0.5mm can ensure the supporting function of the central support 1 while minimizing its occupation of the overall size of the cleaner. This avoids the cleaner being unable to insert into narrow pipes due to the central support 1 being too thick, and at the same time, it will not interfere with the compression and rebound of the first soft melamine foam layer 4 and the second soft melamine foam layer 5, thus taking into account both the scene adaptability and structural functionality of the cleaner.

[0044] See Figure 1 , Figure 2 and Figure 3 The cleaner's length ranges from 1m to 50m, a flexible range that can adapt to the cleaning needs of pipes of different lengths. It can meet the cleaning needs of short-distance, small-diameter pipes as well as cover long-distance pipes (such as industrial long-distance pipelines and household long drainage pipes), eliminating the need for frequent splicing of the cleaner and improving operational convenience. In addition, the 1m to 50m length design ensures the cleaning range while avoiding problems such as incomplete cleaning due to excessive length or the cleaner getting stuck and difficult to operate due to excessive length. It balances cleaning coverage and operational practicality, further expanding the range of applicable scenarios for the cleaner.

[0045] See Figure 1 , Figure 2 and Figure 3In this embodiment, the present invention combines the physical stain removal ability of soft melamine foam with the oil stain removal ability of organic solvent 6. Utilizing the easily compressible nature of soft melamine foam, when using this invention to remove oil stains in confined spaces, the first soft melamine foam layer 4 and the second soft melamine foam layer 5 are compressed and wrapped with a water-soluble film 3 and fixed with a fixing clamp 8. This ensures that the first and second soft melamine foam layers 4 and 5 have small diameters when dry, making them easier to enter the confined space. Simultaneously, an organic solvent 6 encapsulated in a plastic film 7 is placed in the solvent gap 9 between the first and second soft melamine foam layers 4 and 5. In use, firstly, a cleaning device of appropriate length is cut according to the length of the confined space; then, the cleaning unit 2 is pressed slightly until the organic solvent... When the plastic film 7 of the agent 6 breaks, the organic solvent 6 penetrates into the first soft melamine foam layer 4 and the second soft melamine foam layer 5. The second soft melamine foam layer 5, which is soaked in the organic solvent 6, enhances the cleaning effect when wiping oil stains, eliminating the need to spray additional cleaning solvent on the oil stains. Then, the cleaning tool is wetted and placed inside the confined space. The water-soluble film 3 gradually dissolves, and the thickness of the first soft melamine foam layer 4 and the second soft melamine foam layer 5 rebounds to its original thickness. The second soft melamine foam layer 5 fully contacts the inner wall of the pipe. By dragging the central support 1 at both ends of the cleaning strip, the second soft melamine foam layer 5 forms a certain friction with the inner wall of the pipe. In this way, the physical stain removal of the soft melamine foam and the chemical stain removal of the organic solvent 6 are effectively combined, increasing the oil stain removal ability of the cleaner.

[0046] The above description is merely a preferred embodiment of this utility model and is not intended to limit the utility model. Various modifications and variations can be made to this utility model by those skilled in the art. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this utility model should be included within the protection scope of this utility model.
