A valve core structure and a faucet

Abstract

The application discloses a valve core structure and belongs to the technical field of valve core structures. A notch is arranged in the limiting block of the rotating seat, so that the strength of the limiting block in the rotating seat is effectively reduced. After the valve core structure is opened beyond the stroke, the limiting block in the rotating seat can be damaged preferentially, and the positioning protrusions in the valve core shell and the valve core base are not damaged. Thus, the internal function of the valve core structure is normal, and the adverse phenomenon of water leakage does not exist.

[0017] It should be understood that the phrase "one embodiment" or "an embodiment" throughout the specification means that a specific feature, structure, or characteristic related to the embodiment is included in at least one embodiment of the present invention. Therefore, "in one embodiment" or "in an embodiment" appearing throughout the specification do not necessarily refer to the same embodiment. Furthermore, these specific features, structures, or characteristics may be combined in any suitable manner in one or more embodiments.

[0018] Please refer to Figure 1 and Figure 2 , Figure 1 This is an exploded view of a valve core structure provided in an embodiment of this application. Figure 2 This is a cross-sectional view of a valve core structure provided in an embodiment of this application. The valve core structure may include a rotating seat 100 and a valve core housing 200. The rotating seat 100 may be located within the valve core housing 200 and is rotatable relative to the valve core housing 200. The circumferential side of the rotating seat 100 may have at least one limiting block 101. The inner wall of the valve core housing 200 may have limiting protrusions 201 that respectively cooperate with each of the at least one limiting block 101. The limiting block 101 on the rotating seat 100 may have a notch K on the side facing the valve core housing 200. Here, the notch may be located in the middle region of the limiting block 101 and on the side of the limiting block 101 opposite to the rotating seat 100. The cross-sectional shape of the notch K may be square, circular, triangular, or trapezoidal, etc.

[0019] The valve core structure also includes a valve core base 300, which can be installed at the bottom of the valve core housing. The bottom of the valve core base 300 may have a positioning protrusion 301 for positioning and installation with the assembly. The valve core housing 200 and the valve core base 300 are fixedly connected to form an accommodating space. The accommodating space is arranged from top to bottom as follows: valve stem, rotating seat 100, upper valve plate and lower valve plate (not shown in the figure). The middle part of the valve stem is hinged to the rotating seat. The rotating seat 100 is detachably fixedly connected to the upper valve plate. The upper valve plate and the lower valve plate are in contact. The valve core base has adjacent water inlet holes and water outlet holes. The lower valve plate has water inlet guide holes and water outlet guide holes corresponding to the valve core base. The lower end face of the upper valve plate has a water passage groove.

[0020] In this embodiment, by providing a notch K in the limiting block 101 of the rotating seat 100, the strength of the limiting block 101 in the rotating seat 100 is effectively reduced. After the valve core structure overtravels and opens, the limiting block 101 in the rotating seat 100 can be destroyed first, without damaging the positioning protrusion 301 in the valve core housing 200 and the valve core base 300. Thus, the internal function of the valve core structure remains normal, and there is no leakage.

[0021] In summary, this application provides a valve core structure that may include a rotating seat and a valve core housing. By providing a notch in the limiting block of the rotating seat, the strength of the limiting block in the rotating seat is effectively reduced. After the valve core structure overtravels and opens, the limiting block in the rotating seat can be destroyed first, without damaging the positioning protrusions in the valve core housing and valve core base. Thus, the internal function of the valve core structure remains normal, and there will be no leakage.

The weak connecting part 101c can be fastened to the first part 101a and the second part 101b respectively. The thickness of the weak connecting part 101c may be less than the thickness of the first part 101a and the second part 101b, and the first part 101a, the second part 101b, and the weak connecting part 101c can form a notch K. Here, the first connecting part 101a, the weak connecting part 101c, and the second connecting part 101b can be arranged circumferentially along the rotary seat 100.

[0024] In the embodiments of this application, such as Figure 2 As shown, at least one limiting block 101 in the rotating seat 100 may include a first limiting block A1 and a second limiting block A2 disposed opposite to each other, both of which are provided with a notch K. Here, the valve core housing 200 is also provided with a first limiting protrusion B1 and a second limiting protrusion B2 corresponding to the first limiting block A1 and the second limiting block A2.

[0025] In summary, this application provides a valve core structure that may include a rotating seat and a valve core housing. By providing a notch in the limiting block of the rotating seat, the strength of the limiting block in the rotating seat is effectively reduced. After the valve core structure overtravels and opens, the limiting block in the rotating seat can be destroyed first, without damaging the positioning protrusions in the valve core housing and valve core base. Thus, the internal function of the valve core structure remains normal, and there will be no leakage.
