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] Pull-out faucets, with their retractable and rotatable spray heads, offer greater flexibility and convenience and are commonly used in kitchens and bathrooms. They typically feature a pull-out water outlet, as well as cold and hot water inlets. Therefore, the faucet body needs a channel for the pull-out water outlet, an installation structure connecting the cold and hot water inlets, and may even include a water inlet channel connecting the cold and hot water inlets to the valve core. This results in a larger outer diameter for the faucet body, leading to higher costs and a less aesthetically pleasing appearance.

[0003] Although there are existing pull-out faucets with smaller outer diameters, such as the utility model patent with application number 202421037483.8, which discloses a pull-out faucet that divides the pull-out water pipe into a pull-out tube and a spiral tube set inside the water pipe, eliminating the need for a channel for the pull-out water pipe to pass through inside the faucet body, thereby reducing the outer diameter of the faucet body, it has the following shortcomings:

[0004] Because there is no counterweight, the pull-out tube relies on the contraction of the spiral tube and spring to return to its original position after being pulled out. This can lead to incomplete repositioning after prolonged use. Furthermore, the spring mechanism generates significant noise during the pulling-out and repositioning process. Utility Model Content

[0005] In view of this, the purpose of this utility model is to provide a pull-out faucet to solve the above problems.

[0035] Example

[0036] Combination Figures 1 to 9 As shown, this embodiment provides a pull-out faucet, including a faucet body 1, a pull-out tube configured with a counterweight, and multiple water-passing components;

[0037] The faucet body 1 is provided with an installation step 2. The installation step 2 is provided with a pull channel 3 for the pull tube to pass through, a water outlet channel connecting to the valve core cavity 4, and at least one water inlet channel connecting to the valve core cavity 4. One end of the water passage component is connected to the bottom end face of the installation step 2 and is connected to the water outlet channel and the water inlet channel respectively. The other end of the water passage component is provided with an installation part and is located outside the bottom end face of the faucet body 1.

[0038] Specifically, in this embodiment, a pull-out faucet capable of dispensing hot water is taken as an example. Figures 3 to 5 As shown, the bottom of the faucet body 1 is provided with the mounting step 2; the side of the faucet body 1 is inclinedly provided with a valve core cavity 4 for installing a temperature regulating valve core. The bottom of the valve core cavity 4, along its axial direction, is provided with a first cold water inlet channel 6, a first hot water inlet channel 7, and a first mixed water outlet channel 8, corresponding to the cold water inlet, hot water inlet, and mixed water outlet of the valve core. On the mounting step 2, on the side away from the valve core cavity 4, along the vertical axial direction, is a pull-out channel 3 for the pull-out pipe to pass through, and a second cold water inlet channel 9, a second hot water inlet channel 10, and a second mixed water outlet channel 11, respectively connected to the first cold water inlet channel 6, the first hot water inlet channel 7, and the first mixed water outlet channel 8. Figure 6 and Figure 7As shown, in this embodiment, there are three water-passing components, which are made of copper pipes 15; one end of each of the three copper pipes 15 is welded to the bottom end face of the second cold water inlet channel 9, the second hot water inlet channel 10, and the second mixed water outlet channel 11 on the mounting step 2.

[0039] By welding the copper tube 15 to the bottom end face of the mounting step 2 of the faucet body 1, no mounting structure is required on the mounting step 2, thereby reducing the outer diameter of the faucet body 1 and giving it an extremely thin and simple appearance.

[0040] Of course, in the second embodiment, such as Figure 8 and Figure 9 As shown, to better ensure the extremely slim and minimalist appearance of the faucet body 1, the second cold water inlet channel 9, the second hot water inlet channel 10, and the second mixed water outlet channel 11 can also be designed as irregularly shaped channels according to actual conditions, so as to make full use of the limited space while ensuring the water inlet and outlet volume. Of course, the welded copper pipe 15 is also an irregularly shaped pipe adapted to the irregularly shaped channels.

[0041] In this embodiment, the mounting portion at the other end of the copper pipe 15 is placed outside the bottom end face of the faucet body 1, which facilitates the installation and connection of the external water inlet pipe and the pull-out pipe.

[0042] In this embodiment, the bottom end face of the mounting step 2 is the bottom end face of the faucet body 1. This facilitates the welding of the copper tube 15. Figure 2 and Figure 7 As shown, the faucet body 1 also includes a first sleeve 12 disposed at the bottom. After the copper tube 15 is welded, it is sleeved onto the bottom of the faucet body 1 and connected by welding. The first sleeve 12 raises the height of the valve core cavity 4 from the mounting surface, making it easier for the user to operate the handle. Of course, the outer diameter of the first sleeve 12 is the same as the outer diameter of the faucet body 1, so as to maintain an extremely thin and minimalist appearance, looking simple and clean. Similarly, the mounting part of the copper tube 15 is located outside the bottom end face of the first sleeve 12, which facilitates the installation and connection of external water inlet pipes and pull-out pipes.

[0043] In the pull-out faucet described above, the pull-out channel 3 within the faucet body 1 can be set to a diameter of 10mm-15mm. The diameter of the faucet body 1 can be set to 20mm-30mm, giving the faucet body 1 an extremely thin and minimalist appearance.

[0044] In the third embodiment, as Figures 10 to 12As shown, the mounting step is detachably disposed within the faucet body. Specifically, the mounting step includes a stepped portion 16 positioned within the faucet body 1 opposite to the valve core cavity 4, and a connecting portion 17 sealingly connected to the stepped portion 16 within the valve core cavity 4. The stepped portion 16 is provided with the pull-out channel 3, as well as the second cold water inlet channel 9, the second hot water inlet channel 10, and the second mixed water outlet channel 11; the connecting portion 17 is provided with the first cold water inlet channel 6, the first hot water inlet channel 7, and the first mixed water outlet channel 8.

[0045] First, the three copper tubes 15 are welded to the bottom of the second cold water inlet channel 9, the second hot water inlet channel 10, and the second mixed water outlet channel 11, respectively. Then, the stepped portion 16 is placed inside the faucet body 1 at the position corresponding to the valve core cavity 4. Next, the connecting portion 17 is inserted from the valve core cavity 4 to form a snap-fit ​​with the stepped portion 16, thereby creating a sealed connection between the inlet and outlet channels. The stepped portion 16 and the connecting portion 17 form a stable connection within the inner cavity of the faucet body 1, the valve core cavity 4, and the valve core's limiting position. This method ensures the extremely thin and simple straight appearance of the faucet body 1 and facilitates its molding.

[0046] It should be noted that the pull-out faucet also includes a water outlet bend 13 rotatably connected to the faucet body 1, and the diameter of the water outlet bend 13 is the same as the diameter of the faucet body 1, giving the entire pull-out faucet an extremely slim and minimalist appearance. A second sleeve 14 is also connected to the lower end of the first sleeve 12, allowing the pull-out faucet to be fixed to the mounting surface via a fastener.

[0047] By welding the copper tube 15 to the bottom end face of the mounting step 2 of the faucet body 1, no mounting structure is needed on the mounting step 2, thus reducing the outer diameter of the faucet body 1 and giving it an extremely thin and minimalist appearance. Furthermore, the water inlet mounting part is located outside the bottom end face of the faucet body 1, facilitating the installation and connection of the external water inlet and pull-out pipe. This pull-out faucet also features a counterweight to ensure effective retraction of the pull-out pipe without noise.
