DETAILED DESCRIPTION

[0036] The technical solutions in the embodiments of the utility model will be clearly and completely described below with reference to the drawings in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, rather than all the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by those skilled in the art without creative labor fall within the protection scope of the utility model.

[0037] As Figures 1-14As shown, a water pressure changeable telescopic water pipe comprises a pipe body 1 and a connector 2 mounted on the end of the pipe body 1, the connector 2 is used for mounting on a faucet, a valve body 3 is arranged between the pipe body 1 and the connector 2, the water pressure through which is increased or decreased by the valve body 3, the water pipe is pressure changed, the valve body 3 is detachably connected to the pipe body 1 and the connector 2. The valve body 3 comprises a pressure increasing mode and a pressure decreasing mode, the increasing mode can be used when the water pressure is too small, the water pressure of the water pipe is increased, and the water pipe can be used for washing a car, washing a floor and the like; the pressure decreasing mode can be switched when the water pressure is too large, and the water pipe can be used for washing hands, washing dishes and the like in a sink. The pressure increasing mode is that the valve body 3 is installed in a forward direction, the water pressure is increased when the water flow passes through the valve body 3, and the water pressure of the water pipe is increased; the pressure decreasing mode is that the valve body 3 is installed in a reverse direction when the water pressure is too large, and the water pressure of the water pipe is decreased; when the water pressure of the faucet is enough for a user to use, the valve body 3 is not needed, the valve body is detachable, and the pipe body 1 and the connector 2 are used separately. The utility model can switch different modes according to different use requirements of the user to the water pressure, is more simple and convenient to use, has more functions, meets the multifunctionality of use of the user, and the experience of use of the user is better.

[0038] The valve body 3 comprises a plurality of spliced pressure change valves 6, the water flow enters the valve body 3 through the connector 2, sequentially passes through each pressure change valve 6, the water pressure is increased when the water flow passes through each pressure change valve 6 when the valve body 3 is installed in a forward direction, the water pressure is decreased when the water flow passes through each pressure change valve 6 when the valve body 3 is installed in a reverse direction, therefore the performance of the valve body 3 can be adjusted by splicing the number of the pressure change valves 6, and the user can actively adjust the pressure change performance of the valve body 3 according to the water pressure, and the utility is stronger.

[0039] The pressure change valve 6 comprises a shell 5 and a first pressure change valve 7 and a second pressure change valve 8 mounted in the shell 5, the second pressure change valve 8 is reverse to the first pressure change valve 7, and the first end of the first pressure change valve 7 is connected to the tail end of the second pressure change valve 8, and the two are communicated with each other, the water flow flows into the second pressure change valve 8 from the first pressure change valve 7 of one of the pressure change valves 6, and then flows into the adjacent first pressure change valve 7, and the water pressure is changed when the water flow passes through each pressure change valve 6.

[0040] The first pressure change valve 7 comprises a first water inlet 9, a first water inlet channel 10 extending forward from the first water inlet 9, a first annular channel 11 extending to one side from the first water inlet 9, and a first pressure change channel 12 extending forward from the end of the first annular channel 11 and communicating with the end of the first water inlet channel 10;

[0041] The second pressure change valve 8 comprises a second water inlet 13, a second water inlet channel 14 extending forward from the second water inlet 13, a second annular channel 15 extending to one side from the second water inlet 13, and a second pressure change channel 16 extending forward from the end of the second annular channel 15 and communicating with the end of the second water inlet channel.

[0042] In the pressure boosting mode, as shown in Figure 4 the first water inlet channel 10 is connected to the second water inlet 13, and the water flow in the first water inlet 9 flows into the first water inlet channel 10, and when the water flow passes through the intersection of the first pressure valve 7 and the second pressure valve 8, it forms two branches, one of which flows into the second water inlet 13, and the other forms a backflow into the first pressure channel 12, and the water in the first pressure channel 12 flows into the first annular channel 11 and re-enters the first water inlet channel 10, and pushes the water originally flowing in the first water inlet channel 10, increasing the water pressure flowing from the first pressure valve 7 to the second water inlet 13, achieving the effect of pressure boosting. Similarly, the water in the second water inlet 13 forms two branches that flow into the second water inlet channel 14 and the second annular channel 15, respectively, and the water in the second annular channel 15 flows into the second pressure channel 16 and re-enters the end of the second water inlet channel 14, and pushes the water originally flowing in the second water inlet channel 14, further achieving the effect of pressure boosting, and so on. The number of pressure valves 6 can be set to control the pressure boosting performance of the valve body 3

[0043] In the pressure reducing mode, as shown in Figure 5 the design is installed in reverse, with the other end of the connector 2 connected to the faucet, water enters the first pressure valve 6 from the connector 2, and the water flow at the first water inlet 9 forms two branches that enter the first water inlet channel 10 and the first pressure channel 12, respectively, and the water in the first pressure channel 12 flows back through the first annular channel 11 and re-enters the first water inlet channel 10. Since the backflow of water is opposite to the flow direction of water in the first water inlet channel 10, it provides resistance to the normally flowing water in the first water inlet channel 10, reducing the water pressure flowing to the second inlet. Similarly, the water flow further reduces the water pressure after passing through the second pressure valve 8, and the number of pressure valves 6 can be spliced to adjust the pressure reducing performance.

[0044] The angle between the first water inlet channel 10 and the first pressure channel 12 is 20-35 degrees. If the angle is greater than 35 degrees, the water pressure required to flow into the first pressure channel 12 is larger, and if the water pressure is smaller, it may not be able to pass through the first annular channel 11. The water flow in the first pressure channel 12 is inclined downward, and if the angle is less than 20 degrees, it cannot provide a good downward impact force to the water flow, and the pressure boosting effect is general. Therefore, the angle between the first water inlet channel 10 and the first pressure channel 12 is most suitable within the range of 20-35 degrees.

[0045] The connection between the first annular channel 11 and the first water inlet channel 10 and the first pressure channel 12 is provided with a guide part 17, and the connection between the second annular channel 15 and the second water inlet channel 14 and the second pressure channel 16 is also provided with a guide part 17. The guide part 17 is arc-shaped, which can better guide the backflow of water and help to increase the pressure.

[0046] The connecting part 4 includes a threaded connecting part, and two adjacent variable pressure valves 6 are spliced by threads, and when the threads are completely screwed, the first variable pressure valve 7 is aligned with the second variable pressure valve 8, and water flow can pass through; the connecting part 4 also includes a buckle connecting part, and two adjacent variable pressure valves 6 are spliced by buckling and clamping grooves, which is relatively simple to operate and convenient for users to disassemble or install. Similarly, the joint 2 can also be detachably connected with the valve body 3 by threads or buckling.

[0047] The pipe body 1 is sleeved outside the valve body 3, and the pipe body 1 is locked on the outer surface of the valve body 3 by the locking piece 24, so as to prevent the pipe body 1 from being separated from the valve body 3. The locking mode of the locking piece 24 is that the pipe body 1 is sleeved on the outer surface of the valve body 3, a conical plastic part is sleeved on the outer surface of the pipe body 1, and the locking piece 24 is screwed on the plastic part by threads. The more the pipe body 1 is rotated, the more the plastic part is extruded, until the pipe body 1 is tightly clamped on the valve body 3.

[0048] The pipe body 1 includes an inner telescopic pipe 18 and an outer telescopic pipe 19, and the outer telescopic pipe 19 is wrapped outside the inner telescopic pipe 18. In the use process, water flows into the inner telescopic pipe 18, and the pipe body 1 is telescoped by water pressure. The outer telescopic pipe 19 is made of elastic material, and the outer telescopic pipe 19 includes a soft rubber telescopic pipe. In the use process, the inner telescopic pipe 18 and the outer telescopic pipe 19 are telescoped synchronously. When water flows into the pipe body 1, the pipe body 1 is elongated by the impact of water pressure. The greater the water pressure, the longer the inner telescopic pipe 18 and the outer telescopic pipe 19 are telescoped, and the smaller the water pressure, the less the inner telescopic pipe 18 and the outer telescopic pipe 19 are elongated. When the water injection into the pipe body 1 is stopped, the water pressure decreases, and the inner telescopic pipe 18 and the outer telescopic pipe 19 are retracted by their own elastic force. When not in use, the pipe body 1 is in a contracted state, has a small volume and a light weight, and is convenient for users to carry out.

[0049] The inner telescopic pipe 18 is composed of a plurality of corrugated pipes 20 and a plurality of elastic rubber layers 21 in the longitudinal direction, the corrugated pipes 20 are separated in the longitudinal direction, the rubber layers 21 are arranged at intervals between the corrugated pipes 20, and one rubber layer 21 is arranged between every two corrugated pipes 20. The corrugated pipes 20 are plastic corrugated pipes and are expanded and contracted through a plurality of folds. The rubber layers 21 are rubber layers or latex layers and have good elasticity and are expanded and contracted through the elasticity of the materials. Compared with the traditional water pipe, the inner telescopic pipe 18 of the design is composed of a plurality of longitudinal corrugated pipes 20 and rubber layers 21. The stress and elasticity of the rubber layers 21 can cause large deformation, the water pipe can be expanded to a larger diameter when the water pressure is too large, the rubber layers 21 are less likely to be broken than the corrugated pipes 5, and thus the water pipe can be effectively prevented from being broken, the telescopic property of the inner telescopic pipe 18 is improved, the inner layer is enhanced to resist bursting, the possibility of bursting under water pressure is reduced, the adhesion strength between the inner and outer layers is improved, and the service life of the water pipe is prolonged through a plurality of structures, such as the combination of the corrugated and solid forms, under the premise of enhancing the telescopic property of the water pipe.

[0050] The corrugated pipes 20 and the rubber layers 21 are integrally formed, the connecting structure is avoided, the strength is increased, and the production is facilitated.

[0051] The outer telescopic pipe 19 is provided with a lower corrugated surface 22 on the inner surface, the inner telescopic pipe 18 is provided with an upper corrugated surface 23 matched with the lower corrugated surface 22 on the outer surface, the upper corrugated surface 23 and the lower corrugated surface 22 are matched with each other, the contact area between the outer telescopic pipe 19 and the inner telescopic pipe 18 is further increased, the friction is increased, and the inner telescopic pipe 18 and the outer telescopic pipe 19 are matched more closely and are less likely to be separated.

[0052] It is apparent for those skilled in the art that the present application is not limited to the details of the foregoing exemplary embodiments, and the present application can be implemented in other concrete forms without departing from the spirit or essential characteristics of the present application. Therefore, the foregoing embodiments should be considered as exemplary and not limiting, and the scope of the present application is defined by the appended claims rather than the foregoing description, and all changes falling within the meaning and range of equivalents of the claims are intended to be embraced therein, and any reference signs in the claims should not be considered as limiting the claims to which they relate.
