Description

Technical Field

[0001] The present invention relates to the field of sanitary wares, and particularly to a pull-out hovering device and a pull-out faucet. Background Art

[0002] Currently, in the field of sanitary wares, some existing faucets adopt a pull-out part structure. Users can pull out the head of the pull-out faucet together with the water pipe, which is convenient for adjusting the water outlet direction. The pull-out part can automatically reset after the user finishes using it, or a weight is installed at the end of the pull-out part to assist its reset. In order to enable the pull-out faucet to be fixed at the pulled-out position without manual force from the user, a hovering technology has emerged, that is, a hovering mechanism is set. When the user pulls the pull-out part to the target position, the hovering mechanism fixes the pull-out part to make it stop at this position. However, there are some problems in the existing hovering technology. For example, there is only one fixed hovering position. For example, when the user pulls out 40 cm and the hovering mechanism makes the pull-out part hover, then the faucet can only hover at the pulled-out distance of 40 cm at this time, and cannot hover at 30 cm, 20 cm or a certain position actually required by the user. The existing hovering mechanism cannot achieve random stop and stepless stop. In addition, in the existing hovering technology, if the user needs to reset the pull-out part during use, the user needs to pull the pull-out part again to realize the mechanism unlocking and retracting the pulled-out hose, which is cumbersome to operate and not convenient enough to use. In addition, the existing hovering mechanism is relatively long and occupies more space. Summary of the Invention

[0031] An embodiment of the present application provides a pull-out hovering device, which is applied to a pull-out faucet. The pull-out faucet includes a pull-out part. Refer to Figures 1 - 3 As shown, the pull-out hovering device includes a fixing body 1. An over-tube cavity 11, an electromagnet 2 and a clamping member 3 are provided in the fixing body 1. The over-tube cavity 11 is used for the pull-out part to pass through. The clamping member 3 is movably disposed in the fixing body 1. When the pull-out part passes through the over-tube cavity 11, the clamping member 3 is sleeved outside the pull-out part. The clamping member 3 includes a ferromagnetic part 31. The ferromagnetic part 31 is made of a ferromagnetic material. The ferromagnetic part 31 is disposed opposite to one end of the iron core of the electromagnet 2. When the electromagnet 2 is energized, the ferromagnetic part 31 is attracted by the electromagnet 2, so that the pull-out part is jointly squeezed by the clamping member 3 and the cavity wall of the over-tube cavity 11, so that the pull-out part hovers.

[0032] In this embodiment, the clamping member 3 is movably arranged in the fixed body 1. When the pulling part passes through the lumen 11, the clamping member 3 is sleeved on the pulling part. When the electromagnet 2 is powered on, the electromagnet 2 generates magnetism, and the ferromagnetic part 31 arranged opposite to the electromagnet 2 is attracted by the electromagnet 2, thereby driving the entire clamping member 3 to move towards the direction of the electromagnet 2 (when there is a gap between the side of the clamping member opposite to the ferromagnetic part and the pulling part) until it is blocked by the pulling part, or causing the entire clamping member 3 to have a movement tendency towards the electromagnet 2 (when there is no gap between the side of the clamping member opposite to the ferromagnetic part and the pulling part) and being blocked by the pulling part. When the movement or movement tendency of the clamping member 3 is blocked by the pulling part, one side of the pulling part is squeezed by the clamping member 3, and the other side is squeezed by the inner wall of the lumen 11. The pulling part that is squeezed on both radial sides is then suspended. When the electromagnet 2 is powered off, the magnetism of the electromagnet 2 disappears and no longer attracts the ferromagnetic part 31. Since the ferromagnetic part 31 is no longer attracted by the electromagnet 2, the movement tendency of the clamping member 3 towards the electromagnet 2 that was originally blocked by the pulling part disappears, and no longer exerts a squeezing force on the pulling part. Therefore, correspondingly, the squeezing force of the inner wall of the lumen 11 on the pulling part also no longer exists. At this time, the pulling part returns to the state where it can be freely pulled. It can be seen from this that through the pulling and suspending device of this embodiment, stepless suspension of the pulling part can be achieved. Wherever the user hopes to suspend the pulling part, the pulling part can be suspended by controlling the power-on of the electromagnet.

[0033] Reference Figure 1 、 Figure 2 As shown, in some embodiments, an electromagnet installation cavity 12 is provided in the fixed body 1, the electromagnet 2 is arranged in the electromagnet installation cavity 12, and the iron core of the electromagnet 2 protrudes from the electromagnet installation cavity 12 and is arranged opposite to the ferromagnetic part 31.

[0035] Reference Figure 3 、 Figure 3 As shown, in some embodiments, the upper end surface of the lumen 11 horizontally extends outwards to form an installation end surface 14, the clamping member 3 is movably arranged on the installation end surface 14, one end of the protruding part 21 is located on the installation end surface 14 and is arranged opposite to the ferromagnetic part 31, so that when the electromagnet 2 is powered on, it attracts the ferromagnetic part 31, and the pulling part is jointly squeezed by the clamping member 3 and the cavity wall of the lumen 11.

[0036] In this embodiment, an installation end face 14 extends outward from the upper end face of the through lumen 11 to provide a support platform for the clamping member 3, as well as a magnetic attraction cooperation platform for the ferromagnetic portion 31 of the clamping member 3 and the protruding portion 21 of the electromagnet 2. In this embodiment, the clamping member 3 being movably arranged on the installation end face 14 means that the clamping member 3 is placed on the installation end face 14 and can move on the installation end face 14 without other stoppers.

The pipe body 61 passes into the housing 5 from the fixed end, passes through the through pipe cavity 11, and exits from the free end 52. One end of the pipe body 61 that exits from the free end 52 is connected to the water outlet part 62.

[0046] Generally, a weight is provided at the tail end of the pipe body 61 to ensure that the pull-out part can be reset.
