Description

Technical Field

[0001] This utility model relates to the field of bathroom faucet technology, specifically to a faucet inner core and a rotating faucet. Background Technology

[0002] Currently, stainless steel faucets are increasingly favored by the market. Traditional high-end faucets usually use stainless steel faucet bodies. For example, a stainless steel faucet disclosed in Chinese patent document CN202322499751.X has internal structures such as hot and cold water inlet channels, water outlet channels, and valve seat mounting cavities formed inside the stainless steel faucet body. That is, the internal structures are directly milled or cast on the stainless steel faucet body. The processing is complicated and requires precision machining, resulting in low manufacturing efficiency and a significant increase in material and production costs.

[0003] To reduce costs, some stainless steel faucets use plastic injection-molded faucet cores, integrating the valve seat and internal water passages onto the core before assembling it into the stainless steel faucet body. This approach offers advantages such as low cost and ease of manufacturing. However, this type of faucet core is only suitable for fixed faucets and cannot be used with rotating faucets.

[0004] Therefore, existing technologies lack a faucet core structure that can both meet the functional requirements of a rotating faucet and reduce manufacturing costs. In view of this, this invention conducts in-depth research on the aforementioned problems and proposes a faucet core and a rotating faucet, thus giving rise to this invention. Utility Model Content

[0005] The purpose of this utility model is to provide a faucet inner core and a rotating faucet. The faucet inner core is designed with structural optimization to meet the functional requirements of the rotating faucet and reduce manufacturing costs.

[0006] To achieve the above objectives, the solution of this utility model is:

[0007] A faucet inner core is a one-piece molded plastic inner core structure, including a valve seat, an inlet channel and an outlet channel respectively connected to the valve seat, and a rotating core groove connected to the outlet channel for installing a rotating core; a positioning structure for positioning the rotating core is formed on the side wall of the rotating core groove.

[0008] The positioning structure is a positioning hole formed on the side wall of the rotating core groove.

[0009] The corresponding positioning hole of the rotating core groove extends outward to form a positioning channel.

[0010] The groove edge of the rotating core groove has a flange that extends outward in a circumferential direction.

[0011] The faucet's inner core has an overall elongated strip-shaped arrangement, with the water inlet channel and the rotating core groove located at opposite ends of the elongated strip-shaped arrangement.

[0012] The inner core of the faucet has a positioning boss formed on the outer side of the end corresponding to the water inlet channel.

[0013] The inner diameter of the rotating core groove is larger than the inner diameter of the water outlet channel, and the bottom of the rotating core groove has an annular support portion.

[0014] A rotating faucet includes a first body, a faucet core assembled within the first body, a second body, and a rotating core connected between the faucet core and the second body to allow them to rotate relative to each other.

[0015] The rotating core has a first rotating body and a second rotating body that rotate relatively movably, and the second rotating body is threadedly connected to the second body; the first rotating body is installed in the rotating core groove of the faucet inner core, and the first body, the rotating core groove and the first rotating body are all provided with corresponding positioning holes and are fixed by fasteners.

[0016] Both the first body and the second body are stainless steel tubes; a wear-resistant ring is fitted on the rotating core and sandwiched between the first body and the second body. The outer circumferential surface of the wear-resistant ring is flush with the outer side of the first body and the second body, and the inner circumferential surface of the wear-resistant ring is close to the rotating core.

[0017] By adopting the above solution, this new type of faucet inner core and rotating faucet has a pre-formed special groove (i.e., rotating core groove) for installing the rotating core during the forming process. Through this design, the faucet inner core can directly integrate the rotating function, replacing the non-rotatable faucet inner core in traditional fixed faucets or the complex design of rotating faucets that relies on the stainless steel body, significantly reducing production costs.

[0022] Label Explanation

[0023] Faucet inner core 1, valve seat 11, water inlet channel 12, water outlet channel 13, rotating core groove 14, positioning hole 141, positioning channel 142, flange 143, annular support part 144, positioning boss 15; first body 2, positioning hole 21; second body 3; rotating core 4; first rotating body 41, positioning hole 411, second rotating body 42, wear-resistant ring 5, valve core 6, valve core handle 7. Detailed Implementation

[0024] The following detailed description of this case is provided in conjunction with the accompanying drawings and specific embodiments.

[0025] This case involves a type of faucet inner core 1, such as... Figure 1-2 As shown, the inner core structure is made of one piece of plastic and includes a valve seat 11, an inlet channel 12 and an outlet channel 13 respectively connected to the valve seat 11, and a rotating core groove 14 connected to the outlet channel 13 for mounting the rotating core. The side wall of the rotating core groove 14 is formed with a positioning structure for positioning the rotating core.

[0026] The basic function of the faucet inner core 1 is to allow hot and cold water to enter, mix, and then exit the water, as well as to regulate its flow. The water inlet channel 12 includes a first water inlet channel and a second water inlet channel arranged side by side, which are used for the intake of hot and cold water, respectively. The valve seat 11 is used to install the valve core. Hot and cold water enter from the first water inlet channel and the second water inlet channel, respectively, and flow into the valve seat 11, where they are controlled by the valve core. The mixed water is then sent to the water outlet channel 13 and flows out through the rotating core installed in the rotating core groove 14.

[0027] The rotating core is a core used in rotating faucets to perform rotation, which is a known technology. The rotating core can have various structural forms. The innovation of this invention lies in the design of integrally forming a rotating core groove 14 on the inner core 1 of the faucet. The specific structural form and specifications of the rotating core groove 14 can be implemented in various ways, as long as it can be adapted to the installed rotating core.

[0028] The positioning structure on the rotating core groove 14 is used to position the rotating core and prevent it from detaching from the rotating core groove 14. The positioning structure does not affect the rotation function of the rotating core itself. In a preferred embodiment, the positioning structure is a positioning hole 141 formed on the side wall of the rotating core groove 14. The rotating core may be provided with corresponding positioning holes. The inner and outer positioning holes are aligned and locked in place by fasteners (such as screws or pins), thus achieving the positioning of the rotating core within the rotating core groove 14.

[0029] In a further preferred embodiment, a positioning channel 142 extends outward from the corresponding positioning hole 141 of the rotating core groove 14. This positioning channel 142 optimizes the guidance of the fastener, facilitates fastener insertion, and improves assembly efficiency; in addition, the positioning channel 142 reinforces the positioning hole 141, preventing deformation of the sidewall of the rotating core groove 14.

[0030] The new faucet inner core 1 has improved adaptability through the design of the pre-set rotating core groove 14. The faucet inner core 1 can be directly adapted to rotating faucets, especially stainless steel rotating faucets, without changing the external structure of the faucet, which significantly expands the application scenarios of the faucet inner core 1.

[0031] The new type of faucet inner core 1 integrates the core functional structure of the faucet. Therefore, in this application, the stainless steel shell of the faucet only needs to provide basic support and appearance, reducing the amount of stainless steel used and the need for precision machining, thus significantly reducing the overall cost.

[0032] The inner core 1 of this new type of faucet can be injection molded in one step, and the rotating core groove 14 does not require secondary processing. It has high production efficiency and good consistency. Both the rotating core groove 14 and the rotating core adopt standardized interfaces, which can simplify the assembly process and reduce labor costs.

[0033] The new faucet inner core 1 adopts an integrated design of rotating core groove 14. The matching accuracy between rotating core groove 14 and rotating core is high, which can reduce the risk of leakage caused by assembly errors. Moreover, the faucet inner core 1 can also compensate for wear through elastic deformation, and can maintain sealing performance even after long-term use.

[0034] like Figure 1-2 As shown, the groove edge of the rotating core groove 14 has a flange 143 extending outward in the circumferential direction. The design of this flange 143 facilitates assembly and also serves as a connecting support.

[0035] like Figure 1-2 As shown, the faucet inner core 1 has an overall elongated strip-shaped arrangement, with the water inlet channel 12 and the rotating core groove 14 located at opposite ends of the elongated strip-shaped arrangement. The elongated structure is rationally laid out, facilitating molding during manufacturing and allowing the faucet inner core 1 to be easily inserted into the faucet for assembly during installation. The rotating core groove 14, located at the end, facilitates a simple and effective connection with the rotating core during application.

[0036] like Figure 1-2 As shown, a positioning boss 15 is formed on the outer side of the end of the faucet inner core 1 corresponding to the water inlet channel 12. During assembly, the faucet inner core 1 is precisely aligned by the positioning boss 15 cooperating with the relevant groove inside the faucet, ensuring axial alignment of the faucet inner core 1 and preventing circumferential rotation.

[0037] like Figure 2As shown, the inner diameter of the rotating core groove 14 is larger than the inner diameter of the water outlet channel 13, and an annular support portion 144 is formed at the bottom of the rotating core groove 14. During assembly, the rotating core directly abuts against the annular support portion 144, eliminating the need for additional judgment of the insertion depth, thus achieving a quick positioning and installation effect, while also providing axial fixation for the rotating core.

[0038] This invention also relates to a rotating faucet, such as Figure 1-4 As shown, the system includes a first body 2, a faucet inner core 1 assembled within the first body 2, a second body 3, and a rotating core 4 connecting the faucet inner core 1 and the second body 3, allowing them to rotate relative to each other. Thus, under the action of the rotating core 4, the second body 3 rotates relative to the first body 2 (faucet inner core 1), allowing the water outlet angle to change freely. A valve core 6 and a valve core handle 7 are installed on the first body 2 at the valve seat 11 corresponding to the faucet inner core 1; this is a conventional design and will not be described in detail here.

[0039] This new type of rotary faucet transfers the core function of the rotary faucet to the inner core 1 of the faucet. The first body 2 and the second body 3 of the faucet can be made of metal, such as stainless steel. The stainless steel faucet body only needs to provide basic support and appearance, which reduces the amount of stainless steel used and the need for precision machining, resulting in a significant reduction in overall cost.

[0040] like Figure 4 As shown, in one specific embodiment of the rotating core 4, there are a first rotating body 41 and a second rotating body 42 that rotate relatively movably. The second rotating body 42 is threadedly connected to the second body 3. The first rotating body 41 is installed in the rotating core groove 14 of the inner core 1 of the faucet. The first body 2, the rotating core groove 14 and the first rotating body 41 are all provided with corresponding positioning holes 21 / 141 / 411. The three sets of positioning holes corresponding to each other inside and outside are locked and fixed by fasteners (not shown in the figure).

[0041] In a preferred embodiment of this novel faucet, both the first body 2 and the second body 3 are stainless steel tubes. Using stainless steel tubes is low-cost and simple to process. Moreover, stainless steel has good corrosion resistance, is safe and hygienic, has reliable strength, long service life, and is environmentally friendly.

[0042] like Figure 3-4 As shown, a wear-resistant ring 5 is fitted onto the rotating core 4, sandwiched between the first body 2 and the second body 3. The outer circumferential surface of the wear-resistant ring 5 is flush with the outer sides of the first body 2 and the second body 3, while the inner circumferential surface of the wear-resistant ring 5 is positioned close to the rotating core 4. This large radial thickness of the wear-resistant ring 5 creates a wide friction interface, which on the one hand prevents direct collision between the first body 2 and the second body 3, thus avoiding abnormal noise; on the other hand, it accommodates machining errors, reduces precision machining costs, and achieves pressure dispersion, extending wear life.

[0043] The above description is only a preferred embodiment of the present invention. All equivalent changes and modifications made within the scope of the claims of the present invention shall fall within the scope of the claims of the present invention.
