Description

Technical Field

[0001] The present application belongs to the technical field of faucet components, and more specifically, relates to a faucet base. Background Art

[0002] The body of a traditional faucet is usually composed of a plurality of components. When the components are assembled, gaps are often generated because the joints cannot be completely sealed. Generally speaking, a sealing ring is set at the gap to prevent water leakage. However, the body of the faucet is prone to leakage due to aging, wear and deformation of the sealing ring after long-term use. Therefore, in order to improve the aforementioned problems, and with the increasing requirements for the quality and durability of faucets in home and commercial environments, the manufacturing technology of one-piece faucets has gradually become the mainstream of the market. The structure of a known one-piece faucet generally includes a body and a foot, wherein the body has an internal water channel for water to flow through, and the foot covers the body. More specifically, during the manufacturing process of the one-piece faucet, the body is first formed and the internal water channel is formed inside the body, and then the foot is covered with the body through a secondary encapsulation method.

[0003] However, when removing or installing a one-piece faucet, the foot is subject to a certain amount of torque, causing it to rotate or separate from the body. Furthermore, because the secondary encapsulation method involves material bonding, the connection between the body and the foot can become unstable after long-term use, thus shortening the product's lifespan. Utility Model Content

[0004] The purpose of the embodiments of the present application is to provide a faucet base to enhance the overall structural strength and thereby extend the service life of the faucet base.

[0005] To achieve the above-mentioned objectives, the present application adopts a technical solution: providing a faucet base, comprising a base body and at least one covering member. The base body includes a connecting pipe and at least one valve seat connected thereto, the base body defining a flow channel therein, the flow channel having an inlet and an outlet, the at least one valve seat comprising a mounting portion and a base, the mounting portion connecting the connecting pipe and the base, the flow channel inlet located at the base, and the flow channel outlet located at the connecting pipe, the mounting portion comprising a coupling structure; the at least one covering member is manufactured from plastic by injection molding and covers the coupling structure of the mounting portion and the base, and the at least one covering member is non-rotatable relative to the base.

[0006] The beneficial effect of the faucet base provided in the present application is that when the faucet base is installed, since the coupling structure is provided between the base body and each of the covering parts, the coupling structure can effectively prevent the covering parts from rotating and separating relative to the base body, thereby improving the overall structural strength of the faucet base and thereby extending the service life of the faucet base.

[0043] In order to explain this application more clearly, a preferred embodiment is given below with detailed description in conjunction with the drawings. Figures 1 to 6 FIG. 1 shows a faucet base 100 according to a first preferred embodiment of the present application, which includes a base body 10 , two covering members 20 and two metal films 30 .

[0044] The seat body 10 includes a connecting tube 12 and two valve seats 14, the two valve seats 14 are respectively connected to the two ends of the connecting tube 12 of the seat body 10, and each valve seat 14 has a receiving portion 142, a mounting portion 144 and a base 146, wherein the receiving portion 142 is connected to the mounting portion 144 and the connecting tube 12, and a receiving groove 1422 is defined in the receiving portion 142; the mounting portion 144 connects the connecting tube 12 and the base 146, and the outer diameter of the mounting portion 144 is larger than the outer diameter of the base 146.

[0045] like Figure 4 As shown, the seat body 10 has a flow channel 16 inside, and the flow channel 16 has an inlet I and an outlet O. In the present embodiment, the flow channel 16 is divided into a central flow channel 162 and an internal flow channel 164. The central flow channel 162 is formed in the connecting tube 12, and the two ends of the central flow channel 162 are respectively connected to the accommodating groove 1422 of each valve seat 14. The outlet O is located in the middle of the connecting tube 12 and is connected to the central flow channel 162; the internal flow channel 164 is formed in each valve seat 14, and the inlet I is located at the bottom end of the base 146, and the internal flow channel 164 is connected to the accommodating groove 1422 and the inlet I.

[0046] like Figures 4 to 6As shown, the base body 10 has an annular groove 18, which is formed by a recessed portion where the mounting portion 144 is connected to the base 146. In this embodiment, the annular groove 18 is L-shaped, and the mounting portion 144 has a coupling structure, which includes a plurality of protrusions 1442, which are spaced apart along the bottom of the annular groove 18.

[0047] Please continue to cooperate Figures 4 to 6 As shown, the two covering members 20 are made of plastic through injection molding and cover the protrusions 1442 and the base 146 of the coupling structure of the mounting portion 144, preventing each covering member 20 from rotating relative to the base 146 of the valve seat 14. More specifically, the portion of each covering member 20 that fills the annular groove 18 is defined as a filling block 22. The portion of each covering member 20 that covers the base 146 is defined as a foot 24, which connects to the filling block 22. The interplay of the protrusions 1442 and the recesses 222 ensures a tight connection between each covering member 20 and the valve seat 14, preventing the covering member 20 from rotating or separating relative to the valve seat 14, thereby enhancing the structural stability and robustness of the faucet base 100.

[0048] In other embodiments, the protrusion 1442 can also be set as one and located at the bottom of the annular groove 18, and the recess 222 is formed into one corresponding to the position and number of the protrusion 1442, which can also achieve the purpose of preventing each of the covering parts 20 from rotating and separating relative to each of the valve seats 14.

[0049] Each metal film 30 covers the outer surface of the foot 24 of each covering member 20, and a threaded structure is formed on the surface of each metal film 30. The provision of each metal film 30 imparts a metallic texture to the exterior of the faucet base 100, enhancing its aesthetics and quality. Furthermore, each metal film 30 is made of a wear-resistant and corrosion-resistant metal, further extending the service life of the faucet base 100.

[0050] See also Figures 7 to 9 , is the faucet base 100A of the second preferred embodiment of the present invention, which has a structure substantially the same as that of the first preferred embodiment, with the difference being that the annular groove 18A of this embodiment is U-shaped, and the coupling structure includes a plurality of protrusions 1442A, which connect the two side groove walls of the annular groove 18A. The differences are described in detail below.

[0051] These protrusions 1442A are arranged at intervals; the portion of each covering member 20A filling the annular groove 18A is defined as a filling block 22A, and the portion of the filling block 22A corresponding to each protrusion 1442A forms a plurality of through-holes 224A, and the protrusions 1442A are respectively passed through the through-holes 224A; the portion of each covering member 20A covering the base 146A is defined as a foot 24A, wherein the foot 24A is connected to the filling block 22A.

[0052] In other embodiments, the protrusions 1442A may also be set as one, and the protrusion 1442A is connected to the two side groove walls of the annular groove 18A, and the through hole 224A is formed into one corresponding to the position and number of the protrusion 1442A; in addition, the protrusion 1442A may also be connected to the groove wall of at least one side of the two side groove walls of the annular groove 18A, which can also achieve the purpose of preventing each of the covering parts 20A from rotating and separating relative to each of the valve seats 14A.

[0053] In summary, when the faucet base 100, 100A is installed, since the coupling structure is provided between the base body 10, 10A and each of the covering parts 20, 20A, the coupling structure can effectively prevent the covering parts 20, 20A from rotating or separating relative to the base body 10, 10A, thereby improving the overall structural strength of the faucet base 100, 100A and thereby extending the service life of the faucet base 100, 100A.
