[0028] Reference Figures 1 to 4 , a pull-out faucet, comprising:

[0029] Faucet body 10;

[0030] A pull-out hose 30, wherein the pull-out hose 30 is disposed in the faucet body 10, wherein a water flow channel 50 is disposed in the pull-out hose 30, and wherein a first cavity is further disposed in the pull-out hose 30, wherein a magnetorheological fluid 60 is disposed in the first cavity;

[0031] A magnetic part, which is disposed near the first cavity and can generate a magnetic field that affects the magnetorheological fluid 60 outward;

[0032] A water outlet 20, the water outlet 20 is connected to the end of the pull hose 30;

[0033] The switch 21 is connected to the magnetic part, and the switch 21 can control the magnetic part.

[0034] In this solution, a pull-out hose 30 is provided in the faucet body 10, and a water flow channel 50 is provided in the pull-out hose 30 for water to flow through. A first cavity is also provided in the pull-out hose 30, and a magnetorheological fluid 60 is provided in the first cavity. The magnetorheological fluid 60 is liquid in the absence of a magnetic field. A magnetic part that can generate a magnetic field is also provided near the first cavity, and a switch 21 is connected to the magnetic part to control whether it generates a magnetic field outward. When in use, under normal circumstances, the switch 21 is in the closed state, and the magnetic part does not generate a magnetic field. When in use, the pull-out hose 30 can be pulled out through the water outlet 20. When the position of the water outlet 20 needs to be fixed, the switch 21 is turned on to drive the magnetic part to generate magnetic force, and the magnetorheological fluid 60 is affected by the magnetic force and hardens, so that the position of the pull-out hose 30 is fixed, which is convenient for users to use. When the position of the water outlet 20 needs to be changed or the shape of the pull-out hose 30 needs to be adjusted, the switch 21 is turned off. After the magnetic force disappears, the magnetorheological fluid 60 returns to liquid, so that the pull-out hose 30 returns to a soft state, which is convenient for operating the pull-out hose 30. Compared with the prior art, this solution can self-support the water outlet 20 when needed, freeing the user's hands, and can adjust the position of the pull-out hose 30 according to specific circumstances, which is more practical and provides a better user experience.

[0035] As a further improvement, in the above scheme, the magnetic part is preferably arranged on a coiled wire 70 connected to a power source on the pull-out hose 30. By virtue of the electromagnetism characteristics of the coiled wire 70, the coiled wire 70 is energized when needed to generate a magnetic field, and when the magnetic field is not needed, the coiled wire 70 is de-energized.

[0036] As a further improvement, it is preferred that a second cavity 80 is provided in the drawer hose 30, and the coiled wire 70 is provided in the second cavity 80, so as to better accommodate the coiled wire 70. Of course, the coiled wire 70 can also be directly wound around the outer periphery of the drawer hose 30, but in this case, since the coiled wire 70 is directly exposed to the outside, it is easy to cause the risk of leakage.

[0037] As a further improvement, the pulling hose 30 preferably includes an inner tube 41 and an outer tube 40 sleeved outside the inner tube 41, the first cavity is formed between the outer tube 40 and the inner tube 41, and the water flow channel 50 is arranged in the inner tube 41. Of course, it can also be the other way around, that is, the water flow channel 50 is arranged between the outer tube 40 and the inner tube 41, and the first cavity is arranged in the inner tube 41.

[0038] As a further improvement, it is preferred that the second chamber 80 is disposed between the inner tube 41 and the outer tube 40 .

[0039] Further improvement is made, considering the difficulty of production, preferably an intermediate tube 42 is provided between the inner tube 41 and the outer tube 40, the first cavity is formed between the inner tube 41 and the intermediate tube 42, the second cavity 80 is formed between the intermediate tube 42 and the outer tube 40, and the coiled wire 70 is wound on the intermediate tube 42, so as to make production easier. Of course, the first cavity and the second cavity 80 can also be arranged in the opposite direction, that is, the second cavity 80 is formed between the inner tube 41 and the intermediate tube 42, and the first cavity is formed between the intermediate tube 42 and the outer tube 40, and the coiled wire 70 is wound on the inner tube 41.

[0040] Of course, other structures can also be used, such as Figure 4 shown.

[0041] As a further improvement, in the above solution, the second preferred embodiment of the magnetic part may also be an electromagnet disposed in the faucet body 10 , and the electromagnet generates a magnetic field sufficient to affect the magnetorheological fluid 60 .

[0042] The third preferred embodiment is that the magnetic part includes a permanent magnet and a shielding box that can cover the permanent magnet, and a driver is provided on the shielding box, and the driver can drive the shielding box to open or close, and the switch 21 is connected to the driver. When in use, when it is necessary to generate a magnetic field to control the hardening of the magnetorheological fluid 60, the switch 21 is turned on, so that the driver opens the shielding box, so that the magnetic field of the permanent magnet can be diffused out, and when the magnetic field is not needed, the switch 21 is turned off, and the driver drives the shielding box to cover, so that the magnetic field of the permanent magnet is contained in the shielding box and cannot be released. In the second preferred and third preferred embodiments, the magnetic part can be installed on the faucet body 10 or the water outlet 20 or the pull-out hose 30, and can be directly fixed to a specific position, but when the magnetic part is fixed to one place, it is required to generate a larger magnetic field, thereby covering the range of motion of the pull-out hose 30.

[0043] In this manner, the coiled wire 70 always moves with the drawer hose 30 and its distance from the magnetorheological fluid 60 does not change significantly, so the purpose can be achieved by generating a relatively weak magnetic field.

[0044] Of course, in this solution, the magnetic part is not limited to the above three methods. Any method that can produce magnetic changes and thus affect the state of the magnetorheological fluid 60 falls within the scope of the magnetic part.

[0045] As a further improvement, considering the convenience of use, it is preferred that the switch 21 is disposed on the surface of the water outlet 20 .

[0046] The above are only preferred embodiments of the present invention, and are not intended to limit the patent scope of the present invention. All equivalent structural changes made using the contents of the present invention's specification and drawings under the inventive concept of the present invention, or directly or indirectly applied in other related technical fields, are included in the patent protection scope of the present invention.
