[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

[0008] Preferably, the upper end of the hose is connected to the pull-out head, and the pull-out head is provided with a water outlet channel communicating with the hose; the pull-out head is provided with a pull-out head control switch to control the water outlet mode.

[0009] Preferably, the faucet outlet pipe is provided with a first limiting boss that restricts the positioning block from moving forward to its limit position along the water flow direction; the faucet outlet pipe is provided with a second limiting boss, and the end of the second spring away from the positioning block abuts against the second limiting boss.

[0010] Preferably, when the second spring inside the faucet outlet pipe is not compressed in its initial state, the first limiting boss is located in the middle of the second spring near the positioning block, and the first limiting boss and the second spring do not interfere with each other.

[0011] Preferably, the hose and the connector are connected by one of the following: threaded connection, quick-connect / quick-plug connection, or snap-fit ​​connection.

[0012] Preferably, when the hose and the connector are connected by a quick-connect / quick-plug connection, the connector includes a connector body and a hose connector head that connects the connector body and the hose. A barbed structure is provided around the end of the hose connector head that contacts the hose, and the barbed structure contacts the inner wall of the hose.

[0013] Preferably, the connector body is a sleeve-shaped structure, and the connector body is provided with a connector mounting hole for the lower end of the hose connector to be inserted.

[0015] Preferably, two wedge-shaped blocks are symmetrically arranged on the connector body around the central axis of the connector body.

[0016] The advantages of this invention are as follows: By adopting the above structure, when the pull-out head is pulled out, the connector and hose move upwards, and the first spring is compressed. This compression continues until the spring force of the first spring causes an imbalance in the forces received by the upper and lower ends of the positioning block. At this point, the first spring gradually releases its compression, and the positioning block moves forward, causing the second spring to compress. When the positioning block reaches the position of the first limiting boss, the second spring stops compressing, and the first spring continues its compression, allowing the pull-out head to be pulled out further. Upon rebound, the first spring returns to its original length, and the positioning block moves against the water flow, causing the hose to move as well. This continues until the forces received by the upper and lower ends of the positioning block become unbalanced. At this point, the second spring returns to its original length, causing the pull-out head to reach its initial position. Releasing the pull-out head causes the first spring to rebound, driving the hose downwards, thus allowing the pull-out head to return to its natural position. Attached Figure Description

Detailed Implementation

[0025] This utility model's multi-stage reset pull-out faucet 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 inner wall of the lower end 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. The faucet outlet pipe 1 is connected to the faucet body, with the end of the faucet outlet pipe 1 connected to the faucet body being the water inlet end and the end of the faucet outlet pipe 1 away from the faucet body being the water outlet end. A pull-out head 8 that cooperates with the faucet outlet pipe 1 is provided on the water outlet end.

[0026] A positioning block 5 is slidably installed inside the faucet outlet pipe 1 for the hose 2 to pass through. A first spring 6 is installed between the connector 3 and the positioning block 5 for the hose 2 to pass through. A second spring 7 is installed between the positioning block 5 and the pull-out head 8 for the hose 2 to pass through.

[0027] By adopting the above structure, when the pull-out head 8 is pulled out, the connector 3 and the hose 2 move upwards, and the first spring 6 is in a compressed state. The compression continues until the spring force of the first spring 6 causes an imbalance in the forces received by the upper and lower ends of the positioning block 5. At this point, the first spring 6 gradually releases its compression, and the positioning block 5 moves forward, causing the second spring 7 to compress. When the positioning block 5 reaches the position of the first limiting boss 10, the second spring 7 stops compressing, and the first spring 6 continues its compression, allowing the pull-out head 8 to be pulled out further. During the rebound, the first spring 6 first returns to its original length, and the positioning block 5 moves against the water flow direction, causing the hose 2 to move together. This continues until the forces received by the upper and lower ends of the positioning block 5 become unbalanced, at which point the second spring 7 returns to its original length, causing the pull-out head 8 to reach its initial position. Releasing the pull-out head 8 causes the first spring 6 to rebound, driving the hose 2 downwards, thus allowing the pull-out head 8 to return to its natural position.

[0028] The aforementioned hose 2 is distributed along the length of the faucet outlet pipe 1. The upper end of the hose 2 is connected to the pull head 8. The pull head 8 is provided with a water outlet channel that communicates with the hose 2. The pull head 8 is provided with a pull head control switch 9 that controls the water outlet mode.

[0029] To limit the travel distance, a first limiting boss 10 is provided inside the faucet outlet pipe 1 to limit the movement of the positioning block 5 to its limit position along the water flow direction; a second limiting boss 11 is provided inside the faucet outlet pipe 1, and the end of the second spring 7 away from the positioning block 5 abuts against the second limiting boss 11. When the second spring 7 inside the faucet outlet pipe 1 is initially uncompressed, the first limiting boss 10 is located in the middle of the second spring 7 near the positioning block 5, and there is no movement interference between the first limiting boss 10 and the second spring 7.

[0030] To accommodate hoses 2 of different diameters, the hose and the connector 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 3As shown, the connector 3 includes a connector body 31 and a hose connector 32 connecting 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, and the barbed structure 33 contacts the inner wall of the hose 2. The connector body 31 is a sleeve-shaped structure, and a connector mounting hole 34 is provided on the connector body 31 for the lower end of the hose connector 32 to be inserted. A first sealing element 35 is provided between the hose connector 32 and the connector mounting hole 34, and a second sealing element 36 is provided between the connector body 31 and the faucet outlet pipe 1.

[0031] To ensure a reliable connection between the connector body 31 and the hose connector 32, the connector body 31 is provided with wedge-shaped blocks 37 radially distributed along the connector body 31 and passing through both the connector body 31 and the hose connector 32. The connector body 31 has through wedge-shaped holes through which the wedge-shaped blocks 37 pass, and the hose connector 32 has wedge-shaped grooves for positioning and abutting against 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] The initial position of the aforementioned connector 3 is located near the faucet body of the faucet outlet pipe 1; the faucet outlet pipe 1 is threadedly fitted to the faucet body; the stroke end of connector 3 does not exceed the vertical section on 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.
