Description

Technical Field

[0001] The utility model relates to the technical field of faucets, and in particular to a spring-return pull-out faucet with magnetic assistance. Background Art

[0002] Currently, most pull-out faucets return to their original position after use by relying on the gravity provided by a weight hung on the pull-out hose. However, because the weight occupies the already narrow space under the countertop, this can sometimes cause the pull-out process to be awkward. Therefore, a pull-out faucet solution has been developed that uses a spring as the driving force to return the pull-out spout. However, to overcome the friction and back pressure caused by water pressure during the pull-out process, especially in the final stroke of the spring return, the spring's elastic force decreases, making it prone to not returning to its original position. Therefore, the spring is designed with a relatively large preload. However, a large preload also brings two problems: 1. The user's hand feeling when pulling it out will be heavier, resulting in a poor user experience; 2. The pull-out hose is pulled by a large force for a long time, which will affect the life of the hose. Utility Model Content

[0020] Combine Figures 1 to 3 As shown, this embodiment provides a spring-return pull-out faucet with magnetic assistance, comprising a faucet body 1, a first water pipe 2 arranged on the faucet body 1, and a second water pipe 3 which is sleeved outside the first water pipe 2 and can move along the axis of the first water pipe 2. It also includes an elastic member 4 and a magnetic component 5 connected to the second water pipe 3; wherein the elastic member 4 is suitable for providing a rebound force to the second water pipe 3 to return along the axis of the first water pipe 2; the magnetic component 5 is suitable for assisting the elastic member to reset the second water pipe 3 when the second water pipe 3 returns.

[0021] In this embodiment, the faucet body 1 includes a main body 11, an elbow 12, a spout, and other components. A first water pipe 2 connects to the main body 11 for water intake. A second water pipe 3 is sleeved outside and communicates with the first water pipe 2. The end of the second water pipe 3 connects to a pull-out head 13 for water discharge. The second water pipe 3 is movably sealed against the outer wall of the first water pipe 2 and is adapted to slide along the axis of the first water pipe 2 when the user pulls the second water pipe 3.

[0022] Combine Figure 1 and Figure 3 As shown, the elastic member 4 is disposed on the outside of the second water pipe 3. When the second water pipe 3 is pulled, the elastic member 4 is compressed or stretched to generate an elastic restoring force. When the user's pulling force is removed from the second water pipe 3, the elastic restoring force of the elastic member 4 pulls the second water pipe 3 back to its initial position. It should be noted that in this embodiment, the elastic member 4 has a certain amount of pre-compression or pre-tension even when not pulled. Specifically, the elastic member 4 can be a spring. Here, using a compression spring as an example to generate the elastic restoring force, a fixing bracket 14 is provided on the faucet body 1. The fixing bracket 14 is used to mount the spring and limit the movement of one end of the spring. For example, the fixing bracket 14 limits the movement of the spring near the pull-out head 13. The other end of the spring is connected to the end of the second water pipe 3 away from the pull-out head 13. Therefore, when the second water pipe 3 is pulled, the spring is compressed, causing the spring to accumulate force. In one embodiment, the fixing bracket 14 is provided with a step that matches the elastic member 4. One end of the elastic member 4 contacts the step, and the other end is connected to one end of the second water passage 3. This stretches or compresses the elastic member 4 during withdrawal, thereby accumulating force in the elastic member 4. In another embodiment, by positioning the fixed end of the spring near one end of the body 11, the second water passage 3 can be reset by utilizing an elastic restoring force generated by a tension spring. The principle of this method is similar to that of utilizing an elastic restoring force generated by a compression spring, and will not be further described here.

[0023] Combine Figures 1 to 3As shown, the magnetic assembly 5 includes a magnetic member 51 and an adsorption member 52, wherein the adsorption member 52 is provided on the second water pipe 3, and the magnetic member 51 is fixed to the faucet body 1 or the first water pipe 2 to generate a suction force on the adsorption member 52 when the adsorption member 52 approaches, thereby assisting the elastic member 4 in providing a driving force for returning the second water pipe 3. By providing the magnetic assembly 5 here, when the second water pipe 3 is about to return to its initial position, the mutual attraction of the magnetic assembly 5 can provide a force to the second water pipe 3 in the same direction as the elastic restoring force of the elastic member 4. On the one hand, this assists the elastic member 4 in fully returning the second water pipe 3, and on the other hand, it ensures that the position of the second water pipe 3 is stable after the return and does not shake in the pulling direction.

[0024] In one embodiment, the magnetic member 51 is disposed at one end of the first water pipe 2, and the adsorption member 52 is disposed at the end of the second water pipe 3 near the magnetic member 51. That is, the magnetic member 51 is disposed on the first water pipe 2 or the faucet body 1, and the adsorption member 52 is disposed at the end of the second water pipe 3 near the faucet body 1, and auxiliary adsorption is performed at the end, which can reduce installation space.

[0025] In another embodiment, the magnetic component 51 can be disposed within the curved pipe 12 and at one end close to the pull head 13, and the adsorption component 52 can be disposed at one end of the second water-passing pipe 3 close to the pull head 13 to mate with the magnetic component 51. Placing the magnetic component 5 close to the pull head 13 can also achieve an auxiliary return effect, and because it is closer to the pull head 13, a smaller force can be used to overcome the magnetic force and separate the adsorption component 52 from the magnetic component 51.

[0026] It should be noted that, in other embodiments, the magnetic component 5 can be set at other positions along the moving path of the second water pipe 3, and can also play the role of assisting the pull-back.

[0027] In the above embodiment, the magnetic member 51 may be a magnet, and the adsorption member 52 may be another magnetic member 51 or a metal iron member that can attract the magnetic member 51 .

[0028] In another embodiment, the magnetic assembly 5 includes a magnetic member 51 and an adsorbent member 52. The magnetic member 51 is positioned on the second water passage 3, while the adsorbent member 52 is fixed to the faucet body 1 or the first water passage 2. When the magnetic member 51 approaches, it attracts the magnetic member 51, thereby assisting the elastic member 4 in providing a driving force to return the second water passage 3. In other words, the same effect can be achieved by positioning the magnetic member 51 on the second water passage 3 and the adsorbent member 52 on the faucet body 1 or the first water passage 2. Furthermore, in this embodiment, the magnetic assembly 5 can also be positioned at various locations along the path of movement of the second water passage 3.

[0029] This embodiment adds a set of magnetic assisted return on the basis of the pure spring-driven return solution, which can appropriately reduce the pre-pressure value or pre-tension value of the spring to solve the problem of large pre-pressure required by the existing spring. The principle of magnetic assisted return is that the elastic force of the last section of the pull-out return stroke is reduced, allowing the magnetic force to intervene, and the auxiliary spring pulls the second water pipe 3 back to the set position, so that the second water pipe 3 can be accurately reset, improving the experience of the elastic pull-out system while reducing or even avoiding the long-term tension state of the pull-out pipe, effectively protecting the life of the pull-out pipe.

[0030] It should be understood that the above are only preferred implementations of the present invention, and the protection scope of the present invention is not limited to the above embodiments. All technical solutions under the concept of the present invention fall within the protection scope of the present invention.

[0031] The above description of the drawings used in the implementation manner only shows certain embodiments of the present invention and should not be regarded as limiting the scope. For ordinary technicians in this field, other relevant drawings can be obtained based on these drawings without paying any creative work.
