[0025] In the description of this utility model, unless otherwise explicitly defined, terms such as "setting," "installation," and "connection" should be interpreted broadly, and those skilled in the art can reasonably determine the specific meaning of the above terms in this utility model in conjunction with the specific content of the technical solution.

[0026] According to one embodiment of the present invention, a pull-out single-pipe faucet is provided. For example... Figures 1 to 5As shown, the pull-out single-pipe faucet includes an installation pipe 1, a pull-out pipe, a pull-out head 2, and a switch 3. The pull-out pipe is at least partially disposed within the installation pipe 1 and is telescopic relative to the installation pipe 1. One end of the pull-out pipe passes through the installation pipe 1 and enters below the mounting surface, allowing the water inlet end of the pull-out pipe to connect to a water inlet pipe. The other end of the water inlet pipe is connected to a tap water pipe or other water source pipe. The pull-out pipe has a flexible hose structure with a counterweight connected to its middle section, thus the pull-out pipe tends to be pulled downwards by the weight of the counterweight. The pull-out head 2 is connected to the water outlet end of the pull-out pipe and has a first water outlet channel connected to the pull-out pipe. The switch 3 is installed on the pull-out head 2 and is used to open or close the first water outlet channel.

[0027] In this example, the switch 3 of the pull-out single-pipe faucet is set on the pull-out head 2. When using it, the user can turn on the switch 3 at the same time as pulling out the pull-out head 2, and water will come out from the pull-out head 2. This greatly facilitates the user's operation. In addition, the user can also turn on the faucet as needed and turn it off in time after use, which helps to reduce the waste of water resources.

[0028] It should be noted that the mounting tube 1 can be installed on the countertop or sink counter, and the pull-out tube is movably inserted within the mounting tube 1. The mounting tube 1 serves to protect and guide the pull-out tube. The water inlet end of the pull-out tube passes through the mounting tube 1 and connects to the water inlet pipe, while the water outlet end of the pull-out tube connects to the pull-out head 2. The pull-out head 2 is movable relative to the mounting tube 1, meaning that the pull-out head 2 can pull out part of the pull-out tube, allowing the user to aim the water outlet 4 of the pull-out head 2 at the item to be washed. A counterweight is connected to the portion of the pull-out tube below the mounting countertop. When the user releases the pull-out head 2, the counterweight moves downward, thereby causing the pull-out tube to pull the pull-out head 2 to automatically reset.

[0029] In this example, the switch 3 includes a first press button, which, when pressed, opens or closes the first water outlet channel. Adjusting the switch 3 by pressing it facilitates user operation.

[0030] It should be noted that the switch 3 also includes a valve body, which is disposed in the first channel. The first pressing key is connected to the valve body and protrudes from the outer casing 21. By pressing the first pressing key, the valve body can be moved, thereby opening or closing the first water outlet channel.

[0031] For example, the structure of the switch 3 can be similar to that of a push-button switch for a water dispenser. The internal components of the switch 3 include a spring, a piston, and a valve. When the first button is pressed, it pushes the piston to move, compresses the spring, and opens the valve, opening the first water outlet channel and allowing water to flow out. When the first button is released, the spring returns, the valve closes, the first water outlet channel is closed, and the water flow stops.

[0032] Alternatively, the switch 3 can be configured such that when the first press button is pressed to the position and then released, the first water outlet channel opens and water can flow continuously; after use, pressing the first press button again closes the first water outlet channel.

[0033] Alternatively, the switch element 3 can be configured as a rotary valve. Of course, the specific structure of the switch element 3 can be determined by those skilled in the art according to the actual situation, as long as it can control the opening or closing of the first water outlet channel, and no specific limitation is made here.

[0034] like Figures 2 to 5 As shown, according to some embodiments of the present invention, the pull-out head 2 also has a second water outlet channel and a third water outlet channel, and the pull-out single-pipe faucet also includes an adjustment control 6, which is installed on the pull-out head 2 and can adjust the connection between the first water outlet channel and the second or third water outlet channel.

[0035] In this example, the pull-out head 2 also has a second water outlet channel and a third water outlet channel inside, which are arranged side by side. The second and third water outlet channels can be separated by a partition. An adjustment control 6 is installed on the pull-out head 2, and pressing the adjustment control 6 can adjust the connection between the first water outlet channel and the second or third water outlet channel.

[0036] It should be noted that the control panel 6 includes a second press button and a valve body. The second press button is connected to the valve body and protrudes from the outer casing 21. The valve body is located between the outlet end of the first water outlet channel and the inlet ends of the second and third water outlet channels. By pressing the second press button, the valve body can be moved to close the second water outlet channel and open the third water outlet channel; or, the valve body can open the second water outlet channel and close the third water outlet channel; or, the valve body can open both the second and third water outlet channels. Water flows out from different outlet channels, forming different water outlet patterns to adapt to different usage scenarios.

[0037] Alternatively, the control device 6 can also be a rotary adjustment structure. The valve body of the control device 6 is a valve plate with a through hole. By rotating the valve plate, the through hole is connected to the corresponding water outlet channel.

[0038] Of course, the specific structure of the control unit 6 can be determined by those skilled in the art according to the actual situation. It is only necessary to be able to control the water flow to different water outlet channels. No specific limitation is made here.

[0039] like Figure 3 and Figure 4 As shown, according to some embodiments of the present invention, the pull-out single-pipe faucet further includes a spout 4, which is installed on the pull-out head 2. The spout 4 has a first water outlet 41 and a second water outlet 42. The first water outlet 41 is connected to the second water outlet channel, and the second water outlet 42 is connected to the third water outlet channel.

[0040] In this example, the spout 4 is located at the water outlet end of the pull-out head 2. The spout 4 is provided with a first water outlet 41 and a second water outlet 42, each with a different structure. A second water outlet channel and a third water outlet channel are located between the spout 4 and the first water outlet channel. The first water outlet 41 is connected to the second water outlet channel, and the second water outlet 42 is connected to the third water outlet channel. The control switch 6 allows water to flow from either the second or third water outlet channel, or simultaneously from both. That is, water can flow from either the first water outlet 41 or the second water outlet 42, or simultaneously from both, thus allowing for different water flow patterns to be adjusted.

[0041] like Figure 4 As shown, according to some embodiments of the present invention, the first water outlet 41 is provided with a plurality of holes, and the plurality of first water outlet holes 41 are arranged around the second water outlet 42.

[0042] In this example, multiple first water outlet holes 41 can be provided, and these multiple first water outlet holes 41 are arranged around the outer periphery of the second water outlet hole 42. Multiple second water outlet holes 42 can also be provided, with smaller diameters and denser arrangement. The first water outlet holes 41 have larger diameters and are more sparsely arranged.

[0043] Of course, the specific structure and arrangement of the first water outlet 41 and the second water outlet 42 can be determined by those skilled in the art according to the actual situation, and no specific limitation is made here.

[0044] like Figure 5 As shown, according to some embodiments of the present invention, the pull-out head 2 includes a first segment 22 and a second segment 23, one end of the first segment 22 is connected to the second segment 23, the first segment 22 has a first water outlet channel, and the second segment 23 has a second water outlet channel and a third water outlet channel.

[0045] In this example, the first water outlet channel is vertically arranged in the first segment 22. The second and third water outlet channels are arranged side by side in the second segment 23. One end of the first segment 22 is connected to one end of the second segment 23 so that the first water outlet channel can correspond to the second and third water outlet channels. A switch 3 is provided on the first segment 22 for controlling the opening and closing of the first water outlet channel. A control 6 is provided on the second segment 23.

[0046] In this example, the first segment 22 snaps onto the second segment 23. Connecting the first segment 22 and the second segment 23 via a snap-fit ​​method simplifies assembly. Specifically, the first segment 22 has a snap-fit, and the second segment 23 has a slot, allowing the snap-fit ​​to engage securely within the slot.

[0047] Alternatively, the first segment 22 and the second segment 23 can also be connected by means of screws or other methods. Those skilled in the art can decide according to the actual situation, and no specific limitation is made here.

[0048] As shown in the figure and Figure 5 As shown, according to some embodiments of the present invention, the pull-out single-pipe faucet further includes a housing 21, and the first section 22 and the second section 23 are installed inside the housing 21.

[0049] In this example, the first segment 22 and the second segment 23 are installed inside the housing 21, while the switch 3 and the control 6 protrude from the housing 21, facilitating user operation. The housing 21 provides protection for the first segment 22 and the second segment 23. Furthermore, the housing 21 on the outside of the first segment 22 and the second segment 23 also improves aesthetics.

[0050] like Figures 1 to 3 As shown, according to some embodiments of the present invention, the pull-out single-pipe faucet further includes a mounting base 5, and the mounting pipe 1 is mounted on the mounting base 5.

[0051] In this example, the mounting base 5 can be fixedly installed on the countertop or sink countertop by means of snap-fit ​​or fastener screws. The mounting tube 1 is fixedly installed on the mounting base 5.

[0052] According to some embodiments of this utility model, one end of the pull-out head 2 is provided with a limiting part, which can be embedded in the mounting tube 1. When needed, the user can pull out the pull-out head 2 and pull it to a suitable position. After use, the pull tube can drive the pull-out head 2 to reset, and the limiting part of the pull-out head 2 can be partially embedded in the mounting tube 1, thereby fixing and limiting the pull-out head 2, and also improving the aesthetics of the pull-out single-pipe faucet.

[0053] It should be noted that the limiting part can be in the shape of a frustum, with a smaller diameter at the end away from the water outlet 4 and a larger diameter at the end closer to the water outlet 4, so as to play a guiding role and facilitate the smooth pulling of the limiting part of the pull head 2 into the installation tube 1.

[0054] The above embodiments mainly describe the differences between the various embodiments. As long as the different optimization features between the various embodiments are not contradictory, they can be combined to form a better embodiment.
