Detailed Implementation

[0029] The present invention relates to a pull-out faucet installed on the faucet body, comprising a faucet outlet pipe 1 and a flexible hose 2 disposed in the hollow structure of the core of 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. At least one gravity block is provided at the lower end of the flexible hose. When the flexible hose 2 is pulled outward, the connector 3 moves forward along the direction of the faucet outlet pipe 1. After the flexible hose 2 is pulled outward and released, the connector 3 automatically falls back.

[0030] With the above structure, the flexible hose 2 is installed inside the faucet outlet pipe 1. One end of the flexible hose 2 is connected to the connector 3 with an internal water inlet channel 4, and the other end of the flexible hose 2 is connected to the pull-out head 5 with an internal water outlet channel. In use, when the faucet switch on the faucet body is turned on, water begins to flow into the faucet outlet pipe 1. Since the water inlet channel 4 of the connector 3, the flexible hose 2, and the water outlet channel of the pull-out head 5 form a water path, the water flows out through this path from the pull-out head 5. When the pull-out head 5 is pulled outwards, the flexible hose 2 moves outwards along with the pull-out head 5, and the gravity block rises with the flexible hose 2. When the user releases the pull-out head 5, the flexible hose 2 moves downwards under the action of the gravity block, thereby causing the flexible hose 2 to move downwards and the pull-out head 5 to rise back to its initial position.

[0031] The aforementioned faucet outlet pipe 1 is connected to the faucet body. The end of the faucet outlet pipe 1 connected to the faucet body is the water inlet, and the end of the faucet outlet pipe 1 furthest from the faucet body is the water outlet. The flexible hose 2 is distributed along the length of the faucet outlet pipe 1. A pull-out head 5 that cooperates with the faucet outlet pipe 1 is provided on the water outlet. The upper end of the flexible hose 2 is connected to the pull-out head 5. A water outlet channel communicating with the flexible hose 2 is provided inside the pull-out head 5.

[0033] When the gravity block is placed on the lower end of the hose, two gravity blocks are distributed on the hose 2, including a first gravity block 7 and a second gravity block 8 located above the first gravity block 7. The first gravity block 7 and the second gravity block 8 are respectively transition-fitted or interference-fitted with the hose 2. One end of the connector 3 is embedded in the hose 2. When the first gravity block 7 is placed on the hose 2, the first gravity block 7 presses the hose 2 against the end of the connector 3. When the second gravity block 8 is placed on the hose 2, the part of the second gravity block 8 that mates with the hose 2, the end of the connector 3, is not inserted.

[0034] The connector 3 of this utility model includes a cylindrical connector body 31 and a connector head 32 embedded in the connector body 31. One end of the connector head 32 is embedded in a connector mounting hole 33 provided on the connector body 31, and the other end of the connector head 32 is press-fitted with the hose 2. The connector mounting hole 33 is connected to the water inlet channel 4. In order to prevent water from entering the area formed by the connector 3, the faucet outlet pipe 1, and the hose 2, a first sealing element 9 is provided between the connector body 31 and the lower inner wall of the faucet outlet pipe 1. The first sealing element 9 is any one of an ORING sealing ring, a Y-shaped rubber ring, and a Y-shaped silicone ring. A sealing ring 34 is provided between the connector head 32 and the connector mounting hole 33. In order to prevent the hose 2 and the connector head 32 from slipping, a barbed structure 35 is provided around the end of the connector head 32 that contacts the hose 2. The barbed structure 35 contacts the inner wall of the hose 2.

[0035] To ensure a reliable connection between connector 32 and connector body 31, the connector body and connector are either snap-fitted together or connected by a wedge block. When the connector body and connector wedge block are connected, as follows: Figure 1-4 As shown, the connector body 31 is provided with wedge-shaped blocks 36 radially distributed along the connector 3 and passing through the connector body 31 and the connector head 32 respectively. The connector body 31 is provided with through wedge-shaped holes for the wedge-shaped blocks 36 to pass through, and the connector head 32 is provided with wedge-shaped grooves for positioning and abutting the wedge-shaped holes. The wedge-shaped grooves are non-through structures. To further ensure the connection effect, two wedge-shaped blocks 36 are symmetrically arranged on the left and right sides of the central axis of the connector 3.

[0036] The connector 3 of this invention is initially positioned at the lower end of the faucet outlet pipe 1, which is threaded onto the faucet body. A second sealing element 10 is provided between the faucet body and the faucet outlet pipe 1. The second sealing element 10 can be any one of an ORING sealing ring, a Y-shaped rubber ring, or a Y-shaped silicone ring. The travel end of the connector 3 does not exceed the limiting boss 11 provided on the vertical section of the faucet outlet pipe 1, and the limiting boss is used to prevent the connector connected to the lower end of the hose from being completely pulled out.

[0037] 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.
