Description

Technical Field

[0001] The utility model relates to the technical field of automobile supplies, and more specifically discloses a flame-retardant and environmentally friendly hose for new energy vehicles. Background Art

[0002] Automotive hoses, also known as automotive hoses, are special hoses used to transport various liquids and gases (including fuel, lubricating oil, refrigerant and water, etc.) in automobiles. They are mostly distributed in the three major assembly systems of automobile chassis system, engine system and body system, and play the role of oil transportation, gas transportation, water supply, control, power transmission, cooling, heating, etc. They are important parts of automobiles. During the use of existing automotive hoses, due to the needs of actual conditions, it may be necessary to splice the ends of two hoses together. However, the connection method between the existing hoses is not stable enough, which will reduce the later use effect. At the same time, the filter net in the hose cannot be automatically cleaned, which greatly affects the working performance of the hose.

[0003] In view of the above problems, the prior art (publication number CN112727583B) discloses a corrugated silicone tube for automobiles, including a silicone tube body, a cleaning brush and an extrusion groove, wherein a connecting tube is fixedly connected to one end of the silicone tube body, and a filter screen is fixed inside the silicone tube body, and a blade is rotatably connected to the middle of the filter screen, the cleaning brush is fixedly connected to one side of the blade, a sealing gasket is fixedly connected to one side of the silicone tube body, and an extrusion block is embedded inside the silicone tube body, and a slider is fixedly connected to the top of the extrusion block, a sliding groove is provided inside the silicone tube body, and a threaded rod is rotatably connected inside the silicone tube body, and an extrusion rod is penetrated inside the silicone tube body, a spring is sleeved on the outside of the extrusion rod, a limiting groove is provided inside the connecting tube, and an extrusion groove is provided inside the extrusion block. Driven by the airflow, the blade starts to rotate, and the rotation of the blade drives the rotation of the cleaning brush, and the cleaning brush cleans the surface of the filter screen when it rotates.

[0004] However, during use of the above device, the filter can only be cleaned by rotating the cleaning brush, but it is not convenient to clean the dust and impurities accumulated on the surface of the filter out of the hose. When too much dust and impurities accumulate on the surface of the filter, the filter and the hose will still be blocked, affecting the performance of the hose. Utility Model Content

[0005] The main technical problem solved by the utility model is to provide a flame-retardant and environmentally friendly hose for new energy vehicles, which can solve the problem that it is not convenient to clean out the dust and impurities accumulated on the surface of the filter from the inside of the hose.

[0007] Furthermore, the fixing device comprises a fixing block, a spring groove is provided in the middle of the top of the fixing block, a spring is fixed at the bottom of the spring groove, a clamping block is fixed at the top of the spring, and the clamping block is inserted into the inside of the through hole.

[0008] Furthermore, the filtering device includes a first filter tube, a cleaning device is fixed together at the upper and lower middle parts of the inner wall of the first filter tube, a second filter tube is screwed at the left end of the first filter tube, a limiting ring is fixed on the right side of the inner wall of the second filter tube, and a filter net is provided on the right side of the limiting ring.

[0009] Furthermore, the cleaning device includes a support plate, the upper and lower ends of the support plate are fixed to the upper and lower inner walls of the first filter tube, the middle of the left and right sides of the support plate are rotatably connected with a rotating shaft, the right end of the rotating shaft is fixed with a fan blade, and the right end of the rotating shaft is fixed with a cleaning brush.

[0010] Furthermore, the hose body is made of EPDM rubber.

[0011] Furthermore, the left end of the cleaning device contacts the right side of the filter screen.

[0012] The utility model provides a flame retardant and environmentally friendly hose for new energy vehicles with the following beneficial effects: EPDM rubber has good flame retardancy, which ensures the flame retardant and environmentally friendly effect of the hose. When two hoses need to be connected, the plug of one hose is plugged into the inside of the sleeve of the other hose, the position is adjusted to plug the fixing block into the inside of the fixing groove, so that the position of the clamping block is relative to the position of the through hole, and under the action of the spring, the clamping block is plugged into the inside of the through hole, the position of the fixing block and the fixing groove is fixed, and the position of the sleeve and the plug is fixed to complete the connection of the two hoses. When the filter screen accumulates too much dust and impurities, the first filter tube is held tightly and the second filter tube is rotated to separate the first filter tube and the second filter tube. After the filter screen is removed and cleaned or a new filter screen is replaced, the filter screen is placed on the limiting ring, the first filter tube and the second filter tube are tightened, and the left end of the cleaning device and the right side of the limiting ring work together to fix the filter screen. When gas or liquid passes through the inside of the hose, the fan blades are driven to rotate, and the fan blades drive the cleaning brush to rotate through the rotating shaft to clean the filter screen to ensure the use effect.
