[0002] Sinks can be installed in two ways: above-the-counter and under-the-counter. Different sinks have different installation methods, and not all sinks are suitable for all installation methods. Integrated sinks have more restrictions and requirements.

[0003] An integrated sink combines a faucet and sink, with a portion of the faucet's structure fused to the sink. This integration creates installation limitations, making it impossible to freely choose between above- and under-counter sinks. Currently, kitchen countertops are typically made of marble, artificial stone, or slabs, with varying thicknesses and dimensions, typically consisting of one to three layers. This results in a total thickness ranging from 10mm to 30mm. This creates a need for various mounting knobs on integrated sinks to fit within a 10-30mm range, increasing the complexity of the structure. Consequently, most integrated sinks are installed above-the-counter, requiring only the faucet's handle to be secured to the sink countertop. However, installing an under-the-counter sink requires the handle and other components to be disassembled, and the handle must fit within a 10-30mm installation range. Utility Model Content

[0033] See Figures 1-6As shown, the present invention provides a universal countertop mounting structure that mates with a sink countertop 10 and a supporting countertop. The sink countertop 10 is provided with a mounting hole 101. The supporting countertop is typically, but not limited to, a kitchen countertop 20. The present invention will be described using the kitchen countertop 20 as an example. The mounting structure of the present invention includes a valve core assembly 1, a rotating handle 4, a connecting sleeve 2, and a base 3. The valve core assembly 1 is positioned below the sink countertop 10. The lower end of the connecting sleeve 2 is connected to the valve core assembly 1, and the connecting sleeve 2 is inserted into the mounting hole 101 of the sink countertop. The valve core assembly 1 is provided with an upwardly extending extension rod 13 that extends into the connecting sleeve 2. The base 3 is sleeved and connected to the connecting sleeve 2. The bottom end of the base 3 abuts against the supporting countertop (i.e., the kitchen countertop 20, hereinafter referred to as the kitchen countertop 20) located above the sink countertop 10, or alternatively, the bottom end of the base 3 abuts against the sink countertop 10 located above the kitchen countertop 20. The rotating handle 4 is located above the sink countertop 10 and the kitchen countertop 20 and is connected to the extension rod 13 .

[0034] In this embodiment, the connection between the connecting sleeve 2 and the valve core assembly 1 is as follows: the lower end of the connecting sleeve 2 is provided with a circle of outwardly projecting limiting bosses 21, and the connecting sleeve 2 also includes a compression nut 5, which is threadedly connected to the top of the valve core assembly 1 and compresses and retains the limiting bosses 21 within the valve core assembly 1. This allows the connecting sleeve 2 to be quickly connected to the valve core assembly 1, and the connection is stable and has a rotation-stopping effect. Of course, the connection between the connecting sleeve 2 and the valve core assembly 1 is not limited to this method. The connecting sleeve 2 and the valve core assembly 1 can also be fixedly connected using threads, screws, snaps, etc.

[0035] In this embodiment, the rotating handle 4 is laterally locked with the extension rod 13 using a set screw 6. The side wall of the connecting sleeve 2 is provided with a notch 22 for providing clearance for the installation and removal of the set screw 6. The notch 22 is in the shape of an elongated strip and extends up and down. The rotating handle 4 is in the shape of a knob, but is not limited to this. The rotating handle 4 has a double-layer side wall. The inner side wall is sleeved on the outside of the extension rod 13 and is provided with a threaded hole. The outer side wall is provided with a clearance hole corresponding to the threaded hole. The set screw 6 passes through the clearance hole and enters the rotating handle 4. It is locked in the threaded hole using an inner hexagonal wrench 62 and pressed against the outer side of the extension rod 13. A color buckle 61 is embedded in the clearance hole of the rotating handle 4. The outer diameter of the connecting sleeve 2 and the outer diameter of the compression nut 5 are both smaller than the inner diameter of the mounting hole 101 of the sink countertop. In this way, when the valve core 11 of the valve core assembly 1 malfunctions, it can be maintained and replaced directly above the sink countertop 10.

[0036] In this embodiment, the base 3 is threadedly connected to the connecting sleeve 2. Therefore, the connecting sleeve 2 has external threads and the base 3 has internal threads. However, the connection method between the base 3 and the connecting sleeve 2 is not limited to this. In other embodiments, the base 3 and the connecting sleeve 2 are locked by screws or snap-fit ​​connection. A sealing ring 31 is mounted on the bottom end surface of the base 3 to seal with the sink countertop 10 or kitchen countertop 20.

[0037] As a preferred embodiment, a shift assembly 7 is disposed between the base 3 and the rotating handle 4 to create a shift sense and generate audible feedback when the rotating handle 4 drives the extension rod 13 to rotate. In this embodiment, the shift assembly 7 includes a wear-resistant gasket 71 and at least one shift rod 72. The wear-resistant gasket 71 is disposed at the top of the base 3 and fixed relative to the base 3.

Specifically, a positioning structure is disposed between the wear-resistant gasket 71 and the base 3. The positioning structure includes multiple positioning posts disposed at the bottom end of the wear-resistant gasket 71 and positioning slots disposed at the top end of the base 3. The positioning posts and positioning slots engage one-to-one. The shift rod 72 is vertically positioned in an inner hole provided in the rotating handle 4 and can rotate with the rotating handle 4. An elastic member 73 is disposed between the shift rod 72 and the rotating handle 4, which forces the lower end of the shift rod 72 to contact the wavy structure 711. Specifically, there are two shift levers 72, but this is not limited to this. The two shift levers 72 are located on opposite sides of the connecting sleeve 2. The rotating handle 4 of the present invention is provided with a support sleeve 74, which is secured to the inner bottom of the rotating handle 4 using multiple screws 75. The lower end of the support sleeve 74 abuts against a wear-resistant washer 71. The lower end of the shift lever 72 passes through the support sleeve 74 and is provided with a lower stepped surface, which abuts against the upper end surface of the support sleeve 74 to limit the shift lever 72 downward. This allows the present invention to utilize the support sleeve 74 to support the rotating handle 4 while also guiding and limiting the shift lever 72. The elastic member 73 is specifically a coil spring, which fits over the shift lever 72 and abuts between the upper stepped surface of the shift lever 72 and the inner top surface of the inner hole in which the shift lever 72 is located. The lower stepped surface is the downward-facing stepped surface, while the upper stepped surface is the upward-facing stepped surface.

[0038] In this embodiment, the valve core assembly 1 includes a valve core 11 and a valve core seat 12. The extension rod 13 is connected to the driving part 111 of the valve core 11 by screws 14. The valve core 11 is installed in the valve core seat 12, and a sealing ring is matched between the outer side of the valve core 11 and the inner side of the valve core seat 12 to achieve lateral sealing of the valve core 11, thereby preventing the base 3 from rotating and loosening up and down when the wrench is tightened, thereby preventing the risk of water leakage caused by the connection sleeve 2. The valve core seat 12 is locked under the sink countertop 10 by screws 15. The above-mentioned clamping nut 5 is threadedly connected to the top of the inner side of the valve core seat 12, and the limiting boss 21 at the lower end of the connection sleeve 2 is compressed between the clamping nut 5 and the valve core 11. The valve core is a mixing water valve core, preferably a thermostatic valve core, and a one-way valve 9 is installed at its cold water inlet end and hot water outlet end respectively to avoid water leakage problems.

[0039] The present invention also includes a protective sleeve 8, which is sleeved on the outside of the connecting sleeve 2 before the connecting sleeve 2 is installed to protect the connecting sleeve 2.
