[0037] To further explain the technical solution of this utility model, the following detailed description is provided through specific embodiments.
[0038] like Figures 1 to 14 As shown, this utility model relates to a faucet inner core 1, which is integrally molded from plastic material. It includes an inlet pipe 11, a valve core seat 12, a connecting pipe 13, a pivot seat 14, and a water outlet connector 15 connected sequentially from bottom to top. The upper end of the inlet pipe 11 is connected to the inlet interface 120 of the valve core seat 12. The lower end of the connecting pipe 13 is connected to the water outlet interface 123 of the valve core seat 12. The pivot seat 14 is located between the connecting pipe 13 and the water outlet connector 15. The water outlet connector 15 and the connecting pipe 13 are connected inside the pivot seat 14. The outer wall of the pivot seat 14 has an annular wall 141 for the bracket 3 to be rotatably fitted. The outer wall of the pivot seat 14 also has an annular limiting groove 142 for axially limiting the bracket 3.
[0039] Thus, the faucet inner core 1 and kitchen faucet of this utility model, through one-piece injection molding of the inner core, replace the original water circuit components assembled from multiple parts, greatly reducing costs. Due to the reduction in connection points, the probability of leakage is significantly reduced. Furthermore, by providing the annular wall 141 and annular limiting groove 142 on the pivot seat 14, the bracket 3 can be easily installed and rotated relative to the inner core. Moreover, the pivot seat 14 also has an installation groove 145 for installing a tactile ring (not shown in the figure). The installation groove 145 is located above the annular limiting groove 142; the tactile ring improves the stability of the bracket 3 during rotation and provides rotational damping, resulting in a better rotational feel.
[0040] Preferably, a positioning protrusion 143 is formed at the lower end of the pivot seat 14, and at least one positioning notch 144 is formed on the positioning protrusion 143; preferably, as Figure 9 As shown, two symmetrically arranged positioning notches 144 are provided. The positioning notches 144 engage with the positioning blocks 22 on the inner wall of the outer shell 2, achieving accurate positioning of the faucet inner core 1 and the outer shell 2. Auxiliary positioning blocks 16 are formed on the water inlet pipe 11, valve core seat 12, and connecting pipe 13. The positioning notches 144 on the positioning protrusion ring 143 cooperate with the positioning blocks inside the outer shell 2, facilitating mutual positioning of the inner core and the inner cavity of the outer shell 2. The auxiliary positioning blocks 16 abut against the inner wall of the outer shell 2, serving as auxiliary positioning.
[0041] Preferably, the inlet pipe 11 includes a cold water pipe 111 and a hot water pipe 112, and the inlet interface on the valve core seat 12 includes a cold water interface 121 and a hot water interface 122 communicating with the cold water pipe 111 and the hot water pipe 112. After the cold water and hot water are respectively delivered to the valve core body 6 through the cold water pipe 111 and the hot water pipe 112, the handle 7 adjusts the mixing ratio to adjust the temperature and control the water flow. The mixed water after being mixed by the valve core body 6 is delivered to the connecting pipe 13 through the outlet interface 123 and then conveyed upward.
[0042] Furthermore, the water outlet connector 15 has an internal thread 151 that is fixedly connected to the hose 4. Preferably, adhesive is applied to the connection between the hose 4 and the internal thread 151 to ensure a firm connection.
[0043] This utility model also provides a kitchen faucet, including a shell 2, a bracket 3, and the aforementioned faucet inner core 1; a side tube 21 is formed on the side of the shell 2, the inner core is sleeved inside the shell 2, and the valve core seat 12 is aligned with the side tube 21; the upper part of the pivot seat 14 extends out of the upper end of the shell 2, and the bracket 3 is rotatably sleeved on the outside of the pivot seat 14; a limiting pin 32 is fixedly connected to the bracket 3, and the limiting pin 32 partially extends into the annular limiting groove 142. If a C-shaped sleeve 31 is installed on the annular limiting groove 142, the limiting pin 32 is fixedly connected to the C-shaped sleeve 31, and the C-shaped sleeve 31 can rotate on the annular limiting groove 142.
[0044] Preferably, the device further includes a hose 4 and a water outlet 5; one end of the hose 4 is connected to the water outlet connector 15, and the other end of the hose 4 is connected to the water outlet 5; the water outlet 5 can be placed on the bracket 3. Furthermore, the bracket 3 has an insertion hole 33 for inserting the water outlet 5.
[0045] Or, such as Figure 13 and Figure 14 As shown, the bracket 3 has a placement portion 34 for connecting the water outlet head 5, and the placement portion 34 has a magnetic attraction portion that cooperates with the water outlet head 5. The water outlet head 5 is connected to the bracket 3 by magnetic attraction, and the water outlet head 5 can be attracted to the magnetic attraction portion of the bracket 3 from the side. The shape of the water outlet head 5 is not limited by the size of the insertion hole 33.
[0046] Compared with existing technologies, this utility model improves the inner core structure by setting a pivot joint, which facilitates the rotational connection of the bracket 3. Furthermore, the integrated structure reduces assembly and connection points, lowering assembly costs and the likelihood of leakage.
[0047] The above embodiments and figures are not intended to limit the product form and style of this utility model. Any appropriate changes or modifications made by those skilled in the art should be considered as not departing from the patent scope of this utility model.
