Technical Field

[0001] The invention relates to the field of faucets, and in particular to an integrated rotating valve core and a kitchen faucet with the valve core. Background Art

[0002] like Figure 1 As shown, it is a schematic diagram of the structure of a kitchen faucet in the prior art, which includes a water outlet pipe 70, a connecting sleeve 80 and a valve core, and the valve core has an outer shell 10, an inner core 20, a movable plate 30, a static plate 40 and a sealing seat 63. A driving claw is formed at the lower part of the inner core 20, and the driving claw drives the movable plate to rotate. A threaded connection end 81 for being fixedly connected to the connecting sleeve 80 is formed at the upper part of the inner core. The connecting sleeve 80 is fixedly connected to the water outlet pipe 70. The diameter of the lower part of the inner core is greater than the diameter of the upper part of the inner core, so that the inner core is stuck in the outer shell and will not fall off from the outer shell. The static plate is located below the movable plate, and the sealing seat is used to seal the lower port of the through hole in the outer shell 10.

[0003] Although the above-mentioned prior art can realize the use of kitchen faucets, since the upper part of the inner core is connected to the connecting sleeve 80 through the threaded connecting end 81, the connection angle between the inner core and the connecting sleeve 80 is not fixed, that is, different products will eventually have inconsistencies in the water outlet angle, that is, some kitchen faucets will discharge water in the middle, while others will discharge water near the middle, which is not consistent.

[0004] In view of this, the applicant conducted in-depth research on the above issues, which led to the present case. Summary of the invention

[0030] In order to further explain the technical solution of the present invention, the present invention is described in detail below through specific embodiments. It should be noted that the same technical features as those in the prior art are numbered the same.

[0031] like Figure 2 As shown, it is a preferred embodiment of an integrated rotating valve core involved in the present invention, including an outer shell 10, an inner core 20, a movable plate 30 and a static plate 40, and a driving claw 211 cooperating with the movable plate 30 is formed at the lower part of the inner core 20.

[0032] Please refer to Figure 4 As shown, the lower portion of the inner core 20 is a thin head portion 21 , and the upper portion of the inner core 20 is a thick head portion 22 . The thin head portion 21 and the thick head portion 22 of the inner core 20 are integrally formed.

[0033] The integrated rotating valve core further includes a rotating positioning structure 50 located between the outer shell 10 and the inner core 20 . The inner core 20 is assembled with the outer shell 10 from top to bottom and connected via the rotating positioning structure 50 .

[0034] The rotation positioning structure 50 is used to prevent the inner core 20 from falling upward from the outer shell 10 when the inner core 20 is installed into the outer shell 10 from top to bottom. That is, when the inner core 20 is installed in place, the inner core 20 will be positioned. In order to achieve this purpose, various structures can be used. The present invention is described as an example of a preferred embodiment as follows:

[0035] The rotation positioning structure 50 has a plurality of balls 51, a through portion 52 formed on the outer shell 10, and a top-limiting portion 53 formed on the inner core 20. The plurality of balls 51 pass through the through portion 52 from outside to inside and cooperate with the top-limiting portion 53 of the inner core 20.

[0036] When the inner core 20 is installed from top to bottom, the installer passes a plurality of balls 51 through the through-portion 52 one by one from the outside to act on the top limiting portion 53 of the inner core 20 , and the outer shell 10 can be used to position the inner core 20 .

[0037] When the entire kitchen faucet is assembled, the outer shell 10 is installed into the faucet body, and then the water outlet pipe 70 and the inner core 20 are assembled and matched, and the assembly of the entire kitchen faucet is completed.

[0038] As a further preferred solution, the through portion 52 is an annular through groove arranged in an annular shape. Of course, it can also be composed of a plurality of through holes arranged at intervals, as long as the ball 51 can pass through.

[0039] In order to prevent the installed ball bearing 51 from falling back, the rotation positioning structure 50 further comprises a sleeve 61 which is slidably mounted outside the outer shell 10, and the sleeve 61 has at least a first working position and a second working position for covering or opening the annular groove. That is, after the ball bearing 51 is installed, the sleeve 61 can be moved so that the sleeve 61 can cover the ball bearing 51, thereby preventing the ball bearing 51 from falling back.

[0040] Thus, the present invention relates to an integrated rotating valve core, which completely subverts the manufacturing and assembly process of the entire valve core and faucet, and realizes the assembly method of the inner core 20 from top to bottom, that is, the inner core 20 is made of one-piece molding, thereby avoiding the disadvantage of the prior art using a threaded connection method, which makes the water outlet state of the water outlet pipe 70 unable to maintain consistency.

[0041] Compared with the prior art, the one-piece inner core 20 of the present invention is inserted into the movable plate 30 from top to bottom, and the movable plate 30 is driven to rotate by the driving claw 211, and the change in the positional relationship between the movable plate 30 and the static plate 40 is used to realize the switching of the water inlet and outlet states; the present invention adopts a method of solving the positioning problem later so that the valve core can be integrally formed, and the positioning problem between the valve core and the outer shell 10 is achieved by a rotating positioning structure 50 (preferably a ball 51).

[0042] like Figure 4 As shown, the integrated rotating valve core also includes a retaining spring 62, and the retaining spring 62 is fixedly sleeved on the inner core 20 and is snap-fittedly connected to the faucet body.

[0043] In addition, the integrated rotating valve core further comprises a sealing seat 63, and the sealing seat 63 is used to seal the connection gap between the outer shell 10 and the faucet body.

[0044] like Figure 3 and Figure 4 As shown, another object of the present invention is to provide a kitchen faucet with such a valve core, including a faucet body, a water outlet pipe 70 and a valve core assembly.

[0045] The valve core assembly adopts an integrated rotating valve core, which has an outer shell 10, an inner core 20, a movable plate 30 and a static plate 40. The lower part of the inner core 20 is a thin head 21, and the upper part of the inner core 20 is a thick head 22. The thin head 21 and the thick head 22 of the inner core 20 are integrally formed.

[0046] A driving claw 211 cooperating with the moving plate 30 is formed at the lower part of the inner core 20, and a vertical liquid guide hole 221 and a plug interface 222 plugged into the water outlet pipe 70 are formed at the upper part of the inner core 20. The plug interface 222 is connected to the vertical liquid guide hole 221. The integrated rotating valve core also includes a rotating positioning structure 50 located between the outer shell 10 and the inner core 20. The inner core 20 is assembled with the outer shell 10 from top to bottom and is connected through the rotating positioning structure 50.

[0047] The above embodiments and drawings do not limit the product form and style of the present invention. Any appropriate changes or modifications made by ordinary technicians in the relevant technical field should be deemed to be within the patent scope of the present invention.
