Description

Technical Field

[0001] This application relates to the field of piping technology, and in particular to a corrugated hose. Background Technology

[0002] Corrugated hoses are flexible pressure-resistant pipe fittings widely used in liquid transportation, electrical wire protection, and equipment connection. The main structure of a corrugated hose includes an inner hose, an outer corrugated tube, and end fittings. Its core feature is its corrugated structure design, which gives it excellent flexibility, fatigue resistance, and pressure resistance.

[0003] Corrugated hoses are mostly used in kitchen and bathroom applications, such as shower hoses. Due to prolonged contact with high-temperature hot water, calcium and magnesium ions in the water combine with carbonate ions at high temperatures to form insoluble substances such as calcium carbonate and calcium sulfate that adhere to the inner wall of the pipe. The only solution is to clean or replace the corrugated hose.

[0004] Currently, corrugated hoses can only be cleaned by disassembling them. However, because corrugated hoses need to maintain a tight seal, repeated disassembly and cleaning can damage the connection, leading to leaks and other problems. Currently, there are some pipes on the market with replaceable connectors. For example, Chinese patent CN219159754U, published on June 9, 2023, discloses a stainless steel corrugated shower hose, including a main nut connector. The main nut connector has a corrugated hose section, and a pipe connector is located at the end of the corrugated hose section away from the main nut connector. A transfer seat is fixedly connected to the corrugated hose section, and a spare nut connector is fixedly connected to the transfer seat. A sealing column is threadedly connected to the interior of the spare nut connector via a threaded section, and a sealing ring is fixedly connected to the end of the sealing column away from the transfer seat.

[0005] The aforementioned application, through the provision of a spare nut connector and a sealing column, allows the use of a spare nut connector after the main nut connector is damaged, avoiding the need to directly replace the pipe. However, the spare nut connector in this application is set perpendicular to the main nut connector, making replacement inconvenient. Therefore, the inventor believes that a corrugated hose that is easy to adjust and use and can be connected to an external pipeline for cleaning should be designed. Utility Model Content

[0006] This application provides a corrugated hose that is easy to adjust and use and can be connected to an external pipeline for cleaning.

[0007] The corrugated hose provided in this application adopts the following technical solution:

The upper end of the outer tube is provided with an adapter sleeve, and the bifurcation can be inserted into the adapter sleeve. A connector is provided on the bifurcation and is connected to the adapter sleeve through the connector. One side of the bifurcation is a water inlet, and the other side of the bifurcation is provided with a plug. A water pressure sensor is provided inside the plug, and an indicator light is electrically connected to the water pressure sensor.

[0009] Preferably, the adapter sleeve includes two cylindrical portions arranged at an acute angle, a connecting portion is provided between the sides of the two cylindrical portions and the connecting portion connects the two cylindrical portions, a sealing plate is movably connected to the connecting portion, the sealing plate can seal the cylindrical portion and the connecting portion, and a connecting ring is provided at the end of the cylindrical portion and is connected to the water inlet, the plug and the outer pipe through the connecting ring.

[0010] Preferably, the end of the cylindrical portion is provided with a step and is engaged with the connecting ring through the step, and the connecting ring is provided with a thread.

[0011] Preferably, the connecting ring includes a first connecting ring and a second connecting ring. There are two first connecting rings, and the two first connecting rings are respectively connected to the water inlet and the plug. The second connecting ring is connected to the water outlet. The second connecting ring has a conical cylindrical structure and the larger end of the second connecting ring faces the outer pipe.

[0012] Preferably, the connector includes a plastic joint and a retaining ring, both of which are hollow sleeves. The plastic joint is inserted into the end of the inner tube, and the retaining ring is located outside the plastic joint, with its inner and outer sides connected to the inner tube and the outer tube, respectively.

[0013] Preferably, the plastic joint is provided with an annular groove and a washer is provided through the annular groove, and a plurality of fixing protrusions are provided on the outer side of the retaining ring.

[0014] Preferably, a sealing ring is provided between the plug and the connecting ring.

[0015] Preferably, the inner tube is a flexible tube made of PVC or rubber, the outer tube is a stainless steel corrugated tube, and the adapter sleeve is made of nylon plastic.

[0016] In summary, this application includes at least one of the following beneficial technical effects:

[0017] 1. This application features a bifurcation section on the inner tube of the corrugated pipe body, with a corresponding adapter sleeve on the outer tube. The bifurcation section can be inserted into the adapter sleeve, which secures the inner tube. Due to the bifurcation design, the upper end of the corrugated pipe body has two inlets: one side is the water inlet, and the other side has a plug. When the corrugated pipe body becomes clogged, the plug can be removed for cleaning, facilitating routine maintenance. Furthermore, a water pressure sensor with an indicator light connected to it is installed inside the plug. When scale buildup inside the pipe reaches a certain level, changes in internal water pressure will alert the user to clean the pipe promptly, making it convenient to use.

[0018] 2. By setting the connecting sleeve as a cylindrical part with an acute-angle intersection and the connecting part, the bifurcation part can be inserted, which is convenient for fixing the inner pipe. At the same time, a sealing plate is set between the connecting parts to seal the outer pipe, prevent dust and other contaminants from entering, and ensure service life. By setting a first connecting ring and a second connecting ring, and with both the water inlet end and the plug connected to the first connecting ring, the water inlet end can be replaced without replacing the pipe in case of failure, which is convenient for emergency maintenance. Meanwhile, the second connecting ring is a conical cylinder with its larger end facing the outer pipe, which can fix the outer pipe and ensure stable connection.

[0019] 3. By setting up plastic joints and retaining rings, the plastic joints can connect the end of the inner pipe, and the retaining rings can connect and fix the inner pipe and the outer pipe, which facilitates installation and fit. At the same time, the plastic joints are equipped with washers, and the outer side of the retaining rings is equipped with fixing protrusions to ensure a tight connection and prevent water leakage.
