[0003] Pull-out faucets are currently widely used, and their convenient pull-out design brings many benefits. Existing pull-out faucets all rely on components such as a gravity hammer located below the faucet body. Furthermore, to ensure a certain pull-out range, the pull-out hose needs to be lengthened, increasing the faucet's production cost. Additionally, the gravity hammer is typically located under the sink, and a lengthy pipe connects the pull-out head to the gravity hammer, further increasing costs. Therefore, how to achieve precise and compact control is a problem that this invention urgently needs to solve. Utility Model Content

[0004] The technical problem to be solved by this utility model is to provide a pull-out faucet with a compact structure and self-resetting characteristics.

[0005] To solve the above-mentioned technical problems, the technical solution of this utility model is as follows: a self-resetting pull-out faucet, wherein the self-resetting pull-out faucet is installed on the faucet body, and its innovation lies in: the self-resetting pull-out faucet includes a faucet outlet pipe and a flexible hose disposed in the faucet outlet pipe, the lower end of the flexible hose being sealed to the lower inner wall of the faucet outlet pipe through a connector, the connector being provided with a water inlet channel communicating with the flexible hose, a limiting boss located on the inner wall of the faucet outlet pipe at the middle of the length direction of the faucet outlet pipe, and a spring being provided between the connector and the limiting boss for the flexible hose to pass through.

One end of the hose is connected to a connector with an internal water inlet channel, and the other end is connected to a pull-out head with an internal water outlet channel. In use, opening the valve body allows water to flow into the faucet's outlet pipe. Since the inlet channel of the connector, the hose, and the outlet channel of the pull-out head form a water path, the water flows out through this path from the pull-out head. When the pull-out head is pulled out, the hose extends with it, and the other end of the hose moves upward within the faucet's outlet pipe, compressing the spring. When the pull-out head is released, the spring returns to its original length from its compressed state, exerting a downward force on the hose, causing the pull-out head to move downward back to its original installation position. The maximum extension distance of the pull-out head is the distance the pull-out head extends beyond the outlet end when the connector rises to the spring's compression limit. This distance is relatively small and suitable for applications requiring short-flow adjustment. Attached Figure Description

Detailed Implementation

[0024] The present invention relates to a self-resetting pull-out faucet, which is installed on the faucet body and includes a faucet outlet pipe 1 and a flexible hose 2 disposed in the faucet outlet pipe 1. The lower end of the flexible hose 2 is sealed to the lower inner wall of the faucet outlet pipe 1 through a connector 3. The connector 3 is provided with a water inlet channel 4 communicating with the flexible hose 2. A limiting boss 5 is provided on the inner wall of the faucet outlet pipe 1 at the middle of the length direction of the faucet outlet pipe 1. A spring 6 is provided between the connector 3 and the limiting boss 5 for the flexible hose 2 to pass through.

[0025] With the above structure, the hose 2 is installed inside the faucet outlet pipe 1. One end of the hose 2 is connected to the connector 3 with an internal water inlet channel 4, and the other end of the hose 2 is connected to the pull-out head 7 with an internal water outlet channel. In use, opening the valve body switch allows water to flow into the faucet outlet pipe 1. Since the water inlet channel 4 of the connector 3, the hose 2, and the water outlet channel of the pull-out head 7 form a water path, the water flows out through this path from the pull-out head 7. When we pull the pull-out head 7, the hose 2 is pulled out along with it, and the other end of the hose 2, the connector 3, moves upward inside the faucet outlet pipe 1, thereby compressing the spring 6. The tensile limit of the pull-out head in this invention is when the spring between the limiting boss and the connector is in its extreme compression position. When we release the pull-out head 7, the spring 6 returns to its original length from its compressed state, applying a downward force to the hose 2. The pull-out head 7 then moves downward with the hose 2 back to its original installation position. The maximum extension distance of the pull-out head is the distance the pull-out head extends beyond the water outlet when the connector is raised to the spring's compression limit. This distance is relatively small and is suitable for applications requiring short-flow water control.

[0026] The faucet outlet pipe 1 of this utility model is connected to the faucet body. The end of the faucet outlet pipe 1 connected to the faucet body is the inlet end, and the end of the faucet outlet pipe 1 away from the faucet body is the outlet end; the flexible hose 2 is distributed along the length of the faucet outlet pipe 1.

[0027] For ease of water control and aesthetic purposes, a pull-out head 7 is provided on the water outlet end to cooperate with the faucet water outlet pipe 1. The upper end of the hose 2 is connected to the pull-out head 7. A water outlet channel communicating with the hose 2 is provided inside the pull-out head 7. A pull-out head control switch 8 is provided on the pull-out head 7 to control the water outlet mode.

[0028] To facilitate quick installation of the spring 6, a cavity 9 is provided between the faucet outlet pipe 1 and the flexible hose 2 for inserting the spring 6. The cavity 9 has a bottom-opening structure, and the connector 3 is located at the bottom opening of the cavity 9, with the diameter of the connector 3 equal to the inner diameter of the cavity 9 at the bottom opening. The outer wall of the cavity 9 has a clearance fit or transition fit with the faucet outlet pipe 1. The cavity 9 has a cavity 9 mounting hole for the flexible hose 2 to pass through. The flexible hose 2 enters the cavity 9 from below through the bottom opening, exits through the cavity 9 mounting hole, and then enters the faucet outlet pipe 1.

[0029] To accommodate hoses 2 of different diameters, the hose 2 and the connector 3 are connected using one of the following methods: threaded connection, quick-connect / quick-fit connection, or snap-fit ​​connection. When the hose and the connector are connected using a quick-connect / quick-fit connection, such as... Figure 3 As shown, the connector 3 includes a connector body 31 and a hose connector 32 that connects the connector body 31 and the hose 2. A barbed structure 33 is provided around the end of the hose connector 32 that contacts the hose 2. The barbed structure 33 contacts the inner wall of the hose 2.

[0030] To ensure a good seal, the connector body 31 is a sleeve-shaped structure. The connector body 31 is provided with a connector mounting hole 34 for the lower end of the hose connector 32 to be inserted. A first sealing element 35 is provided between the connector body 31 and the lower inner wall of the faucet outlet pipe 1, and a second sealing element 36 is provided between the faucet body and the faucet outlet pipe 1. The first sealing element 35 and the second sealing element 36 are any one of an ORING sealing ring, a Y-shaped rubber ring, and a Y-shaped silicone ring.

[0031] To ensure reliable connection, the connector body 31 is provided with wedge-shaped blocks 37 radially distributed along the connector body 31 and passing through the connector body 31 and the hose connector 32 respectively. The connector body 31 is provided with through wedge-shaped holes for the wedge-shaped blocks 37 to pass through, and the hose connector 32 is provided with wedge-shaped grooves for positioning and abutting the wedge-shaped holes. The wedge-shaped grooves are non-through structures. Two wedge-shaped blocks 37 are symmetrically arranged on the left and right sides of the central axis of the connector body 31.

[0032] In its initial position, the connector 3 of this invention is located near the faucet body on the faucet outlet pipe 1. The faucet outlet pipe 1 is threadedly fitted to the faucet body; the end of the travel of the connector 3 does not exceed the limiting boss 5 provided on the vertical section of the faucet outlet pipe 1.

[0033] The above embodiments are merely descriptions for clearly illustrating the present invention and are not intended to limit the implementation. Those skilled in the art can make other variations or modifications based on the above description. It is neither necessary nor possible to exhaustively list all implementations here, and any obvious variations or modifications derived therefrom are still within the protection scope of the present invention.
