Description

Technical Field

[0001] This utility model relates to the field of faucet technology, and more specifically, to a pull-out faucet. Background Technology

[0002] Existing pull-out faucets typically employ a pull-out tube structure, allowing users to pull out the faucet head along with the water pipe for easy adjustment of the water flow direction. This provides flexibility and convenience, making it easy to clean sinks, countertops, and other areas. Additionally, the pull-out tube can return to its original position under its own weight after use, or a counterweight can be installed at the end of the pull-out tube to assist in its return.

[0003] However, the water outlet component of existing pull-out faucets cannot be suspended after being pulled out. This means that users need to overcome the weight of the pull-out tube and the counterweight while using the pull-out tube, and continuously apply pulling force to the pull-out tube. Prolonged use can easily lead to arm fatigue for users. Utility Model Content

Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this utility model. Therefore, the following detailed description of the embodiments of this utility model provided in the accompanying drawings is not intended to limit the scope of the claimed utility model, but merely represents selected embodiments of this utility model. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this utility model.

[0029] Example

[0030] Combination Figures 1 to 6 As shown, this embodiment provides a pull-out faucet, including a pull-out tube 6, a guide tube 5, and a positioning member 8 rotatably disposed on the pull-out tube;

[0031] The inner wall of the guide tube 5 is provided with a curved trajectory guide groove, and the trajectory guide groove is provided with a positioning point 16;

[0032] The positioning element 8 is configured to: move upward along the trajectory guide groove when the pull tube 6 is pulled out, and hover at the nearest positioning point 16 when the pull tube 6 retracts, so that the pull tube 6 will not continue to retract; and move upward again along the trajectory guide groove when the pull tube 6 is pulled out again, so that the pull tube 6 retracts to the initial position.

[0033] By using the guide groove on the inner wall of the guide tube 5 and the positioning point 16, the positioning member 8 moves upward along the guide groove when the pull tube 6 is pulled out, and can hover at the nearest positioning point 16 when the pull tube 6 retracts, so that the pull tube 6 will not continue to retract; when the pull tube 6 is pulled out again, it can move upward along the guide groove again, and can retract the pull tube 6 to the initial position. In this way, the pull tube 6 can be hovered at a certain position when it is pulled out, so that the user does not need to continuously apply pulling force to the pull tube 6 during use, avoiding the fatigue of the user's arm due to long-term use.

[0034] Specifically, in this embodiment, the pull-out faucet includes a body 1, a water outlet bend 2 connected to the body 1, a valve core disposed on the body 1, and an operating handle 3 for controlling the valve core. The pull-out pipe 6 is placed inside the body 1 and the water outlet bend 2, and one end of it is connected to a water outlet nozzle 11. The pull-out pipe 6 is connected to a sleeve 4, and the sleeve 4 fixes the body 1 to the table surface by a fixing seat 12 and a nut.

[0035] In this embodiment, the guide tube 5 is disposed inside the sleeve 4, specifically, as shown below. Figure 5 As shown, the guide tube 5 includes a first semi-circular guide tube and a second semi-circular guide tube, which are provided with the first trajectory guide groove 13 and the second trajectory guide groove 14; and the trajectory guide grooves on the first semi-circular guide tube and the second semi-circular guide tube are symmetrically arranged. Figure 4 As shown, the positioning element 8 is a rotating ring 9 rotatably connected to the pull-out tube 6. The side of the rotating ring 9 is provided with a boss 10 that can move within the trajectory guide groove and hover on the positioning point 16. It should be noted that the first half-ring guide tube and the second half-ring guide tube have the same structure.

[0036] In this embodiment, the lower inlets of the first trajectory guide groove 13 and the second trajectory guide groove 14 are connected to form a trumpet-shaped inlet 20, and a first guide portion 21 is provided, which is used to allow the boss 10 to move upward along the first trajectory guide groove 13 after entering the inlet 20. The trumpet-shaped inlet 20 allows the boss 10 to enter the trajectory guide groove more smoothly during the upward movement.

[0037] In this embodiment, a plurality of positioning islands 15 are spaced apart along the axial direction of the guide tube 5 between the first trajectory guide groove 13 and the second trajectory guide groove 14. The upper end of each positioning island 15 has a groove forming the positioning point 16. The lower end of each positioning island 15 has a second guide portion 17, which includes a first guide edge 18 on one side of the first trajectory guide groove 13 and a second guide edge 19 on one side of the second trajectory guide groove 14. The bottom end of the second guide portion 17 of the previous positioning island 15 is located above the lowest point of the groove on the side of the next positioning island 15 closest to the first trajectory guide groove 13, so that the lowest point of the groove is below the second guide edge 19. A counterweight 7 is provided below the pull-out tube 6 to facilitate rapid retraction of the pull-out tube 6. Thus, when the pull-out tube 6 is pulled out, it can move upward along the first trajectory guide groove 13, and under the action of the counterweight 7, the boss 10 can fall and hover on the groove under the guidance of the first guide edge 18. When the pull-out tube 6 is pulled out again, the boss 10 enters the second trajectory guide groove 14 and moves upward under the guidance of the second guide edge 19, and can move along the second trajectory guide groove 14 under the action of the counterweight 7, falling back to the initial position. The uppermost positioning island 15 forms the closed end of the second trajectory guide groove 14, so that when the pull-out tube 6 is pulled out again, the boss 10 will not disengage from the second trajectory guide groove 14, ensuring that the boss 10 can fall back to the initial position along the second trajectory guide groove 14. This arrangement of multiple positioning islands 15 enables the pull-out tube 6 to have multiple hovering positions.

[0038] In this embodiment, the first and second semi-circular guide tubes are injection molded from plastic. Of course, in other embodiments, the guide tube 5 and the sleeve 4 can also be integral, with the first trajectory guide groove 13 and the second trajectory guide groove 14 directly disposed inside the sleeve 4. Since the sleeve 4 is usually made of metal, it can be divided into two parts along its axis, formed separately, and then welded together. This will not be described in detail.

[0039] In other embodiments, such as Figure 6 As shown, a positioning island 15 is provided between the first trajectory guide groove 13 and the second trajectory guide groove 14. A second guide part 17 is provided above the positioning point 16, and the upper end of the second guide part 17 forms the closed end of the second trajectory guide groove 14. The guide pipe 5 is provided in the bushing 22 of the water outlet bend 2 that is connected to the faucet body 1. This method enables the single-position suspension of the pull-out pipe 6.

[0040] Of course, the upper end of the first track guide groove 13 can also form a trumpet-shaped opening so that when the pull tube 6 is pulled out and the longer boss 10 is separated from the first track guide groove 13, it can fall more smoothly under the action of the counterweight 7 and re-enter the first track guide groove 13, and hover on the positioning point 16.
