Description

Technical Field

[0001] This application relates to the field of automotive parts technology, and in particular to an environmentally friendly automotive hose with dust and sand protection function. Background Technology

[0002] Environmentally friendly automotive hoses are flexible pipes specifically designed for automotive fluid transmission systems. They are used in automotive oil and air systems and are manufactured with low-pollution, recyclable, or biodegradable materials. The aim is to reduce the negative impact on the environment during production and use, while meeting the needs of lightweight, high-efficiency, and long-life automotive applications.

[0003] Existing environmentally friendly automotive hoses, when used in a car under prolonged operating conditions or in hot weather, will cause the temperature inside the engine compartment where the hose is located to rise. When the temperature is too high, the performance of the hose itself will be affected. When the hose is under high temperature for a long time, it will accelerate the aging of the hose, thus affecting the normal use of the hose. Utility Model Content

[0004] The purpose of this application is to address the problem that existing environmentally friendly automotive hoses, when used in long-term operation or in hot weather, cause the temperature inside the engine compartment where the hose is located to rise. When the temperature is too high, the performance of the hose itself will be affected. When the hose is exposed to high temperatures for a long time, the aging rate of the hose will be accelerated, thus affecting the normal use of the hose. This application provides an environmentally friendly automotive hose with dust and sand prevention function.

[0005] To achieve the above objectives, this application specifically adopts the following technical solution:

[0006] An environmentally friendly automotive hose with dust and sand protection function includes a hose body, a connecting pipe fixed to the end of the hose body, a sealing gasket and a filter screen disposed between the hose body and the connecting pipe, the sealing gasket being an EPDM rubber gasket, and the filter screen being a stainless steel microporous screen with a pore size of 50μm and a thickness of 0.2mm. The hose body includes an inner layer, an intermediate layer fixed to the side of the inner layer, an outer layer fixed to the side of the intermediate layer, a pressure-resistant protective layer fixed to the side of the outer layer, and a high-temperature resistant layer disposed on the side of the pressure-resistant protective layer.

[0007] By adopting the above technical solutions, when this hose is put into use and connected to other equipment, the sealing gasket increases the sealing performance between the hose and the connecting pipe. The filter screen filters out dust and sand in the transported liquid, reducing the impact of dust and sand. The pressure-resistant protective layer improves the hose's pressure resistance and bending resistance. The high-temperature resistant layer enhances the hose's high-temperature resistance, reducing the impact of high-temperature environments on the hose.

[0008] Furthermore, the inner layer is a fluororubber layer.

[0009] By adopting the above technical solutions, fluororubber exhibits good high-temperature resistance, improving the high-temperature resistance of the hose, and also has good corrosion resistance, improving the corrosion resistance of the hose.

[0010] Furthermore, the high-temperature resistant layer is a mica tape layer.

[0011] By adopting the above technical solution, the mica tape has good high temperature resistance, which further improves the high temperature resistance of the hose and reduces the impact of high temperature environment on the normal use of the hose.

[0012] Furthermore, the intermediate layer is a reinforcing fiber woven layer, and the outer layer is a high-strength PVC layer.

[0013] By adopting the above technical solutions, the reinforced fiber braided layer can improve the overall strength and pressure resistance of the hose, and expand the range of applications of the hose.

[0014] Furthermore, the pressure-resistant protective layer is a flexible metal wire braided layer.

[0015] By adopting the above technical solution, the flexible metal wire braided layer can improve the bending and impact resistance of the hose, making it more suitable for use.

[0016] Furthermore, a thermal insulation layer is fixed between the pressure-resistant protective layer and the high-temperature resistant layer, and the thermal insulation layer is a polyurethane thermal insulation cotton layer.

[0017] By adopting the above technical solution, the insulation layer can improve the heat preservation capacity of the hose and reduce the impact of external temperature on its normal use.

[0018] Furthermore, a self-cleaning layer is fixed to the side of the high-temperature resistant layer, and the self-cleaning layer is a nano self-cleaning coating.

[0019] By adopting the above technical solution, the self-cleaning layer can prevent dust and dirt from sticking to the surface of the hose, making it easy to clean and maintain.

[0020] Furthermore, an antistatic layer is fixed to the inner side, and the antistatic layer is a conductive carbon fiber layer.

[0021] By adopting the above technical solution, the antistatic layer can reduce the static electricity generated during liquid transportation and reduce the safety hazards caused by static electricity.

[0022] In summary, this application includes at least one of the following beneficial effects:

[0023] 1. The inner layer made of fluororubber has excellent high-temperature resistance, which improves the hose's overall high-temperature performance and reduces the impact of high temperatures. Fluororubber also has good corrosion resistance. Furthermore, the high-temperature resistant layer made of mica tape further enhances the hose's high-temperature resistance and provides good flame retardancy. The combination of the fluororubber inner layer and the mica tape high-temperature resistant layer gives the hose excellent high-temperature resistance, slows down the aging process caused by high temperatures, and reduces the impact of high temperatures on the hose's normal use.

[0024] 2. By incorporating a pressure-resistant protective layer made of flexible braided metal wire, the hose exhibits excellent flexibility and impact resistance, thereby extending its service life. The self-cleaning layer prevents dust and dirt from accumulating on the hose surface, facilitating subsequent cleaning and maintenance. The anti-static layer reduces static electricity, minimizing the fire hazard caused by electrostatic sparks and thus improving long-term safety. Attached Figure Description

[0031] The following is in conjunction with the appendix Figure 1 —4 provides further detailed description of this application.

[0032] This application discloses an environmentally friendly automotive hose with dust and sand prevention function.

[0033] Reference Figures 1-3An environmentally friendly automotive hose with dust and sand prevention function includes a hose body 1, a connecting pipe 2 fixed to the end of the hose body 1, a sealing gasket 3 and a filter screen 4 between the hose body 1 and the connecting pipe 2, the sealing gasket 3 being an EPDM rubber gasket, and the filter screen 4 being a stainless steel microporous screen with a pore size of 50μm and a thickness of 0.2mm. The hose body 1 includes an inner layer 101, an intermediate layer 102 fixed to the side of the inner layer 101, an outer layer 103 fixed to the side of the intermediate layer 102, a pressure-resistant protective layer 104 fixed to the side of the outer layer 103, and a high-temperature resistant layer 106 provided on the side of the pressure-resistant protective layer 104.

[0034] When using this hose, the connecting pipes 2 at both ends of the hose are connected to the corresponding equipment. During use, the sealing gasket 3 provides a good seal, reducing leakage. The filter screen 4 effectively intercepts fine dust and sand particles, acting as a dust and sand preventer. The pressure-resistant protective layer 104 enhances the hose's resistance to pressure and bending. The high-temperature resistant layer 106 improves the hose's high-temperature resistance, effectively reducing hose deformation caused by high temperatures when the hose is in a high-temperature environment.

[0035] The inner layer 101 is a fluororubber layer.

[0036] Among them, the high-temperature resistant layer 106 is a mica tape layer.

[0037] Reference Figure 4 The inner layer 101 made of fluororubber has good high temperature resistance, which can improve the high temperature resistance of the hose and reduce the impact of high temperature on the hose. Fluororubber also has good corrosion resistance. At the same time, the high temperature resistant layer 106 made of mica tape can further improve the high temperature resistance of the hose and has good flame retardant effect.

[0038] Reference Figure 4 The middle layer 102 is a reinforcing fiber woven layer, and the outer layer 103 is a high-strength PVC layer.

[0039] The middle layer 102 is made of high-strength nylon fiber braided layer with a thickness of 0.5mm, which can improve the overall strength and pressure resistance of the hose.

[0040] Reference Figure 4 The pressure-resistant protective layer 104 is a flexible metal wire braided layer.

[0041] The pressure-resistant protective layer 104, made of flexible metal wire braid, gives the hose good flexibility and impact resistance. When the hose is subjected to bending and impact, it can reduce the impact of bending and impact on the use of the hose and improve the service life of the hose.

[0042] Reference Figure 4A thermal insulation layer 105 is fixed between the pressure-resistant protective layer 104 and the high-temperature resistant layer 106. The thermal insulation layer 105 is a polyurethane thermal insulation cotton layer.

[0043] By setting up the insulation layer 105, the insulation effect can be achieved, reducing the impact of excessively low external temperatures on the liquid inside the hose, which is more conducive to the long-term use of the hose.

[0044] Reference Figure 4 A self-cleaning layer 107 is fixed to the side of the high-temperature resistant layer 106. The self-cleaning layer 107 is a nano self-cleaning coating.

[0045] During the use of the hose, the self-cleaning layer 107 makes it less likely for dust and dirt to stick to the surface of the hose, making it easier to clean and maintain later.

[0046] Reference Figure 4 An antistatic layer 108 is fixed to the side of the inner layer 101. The antistatic layer 108 is a conductive carbon fiber layer.

[0047] By setting the antistatic layer 108, static electricity can be reduced, thus reducing the fire hazard caused by static sparks and improving the safety of long-term use.

[0048] Working Principle: When using this hose, the connecting pipes 2 at both ends are connected to the corresponding equipment. During use, the sealing gasket 3 provides a good seal, reducing leakage. The filter screen 4 effectively intercepts fine dust and sand particles, acting as a dust and sand preventer. The anti-static layer 108 reduces static electricity, minimizing the fire hazard caused by static sparks and improving long-term safety. The fluororubber inner layer 101 has excellent high-temperature resistance, improving the hose's high-temperature performance and reducing the impact of high temperatures. Fluororubber also has good corrosion resistance. The middle layer 102 is a high-strength nylon fiber braided layer with a thickness of 0.5mm, enhancing the overall strength and pressure resistance of the hose. The pressure-resistant protective layer 104, made of flexible metal wire braid, provides good flexibility and impact resistance, extending the hose's service life. The insulation layer 105 provides insulation, reducing the impact of low external temperatures on the internal liquid. The high-temperature resistant layer 106, made of mica tape, further improves the hose's high-temperature resistance and also has good flame-retardant properties. By setting the self-cleaning layer 107, the surface of the hose is less prone to dust and dirt accumulation, making cleaning and maintenance convenient.
