[0041] like Figure 1 , Figure 2 and Figure 3 As shown, the embodiment of the present application provides a valve core 100, which is mainly used in valves, and the valves are mainly used in faucets. The valve core 100 includes a housing 110 and a valve stem sleeve 120.
[0042] See also Figure 4 and Figure 5 The housing 110 is provided with a first receiving groove 111 and a through hole 112 communicating with the first receiving groove 111.

[0044] The valve core 100 provided in the embodiment of the present application is provided with a limiting groove 1111 on the bottom wall of the first accommodating groove 111 and connected with the through hole 112, and a limiting protrusion 1221 cooperating with the limiting groove 1111 is protruded on the outer circumferential wall of the second main body portion 122, so as to limit the rotation angle of the limiting protrusion 1221 under the limiting action of the limiting groove 1111 on the limiting protrusion 1221, thereby realizing the opening, closing and flow regulation of the valve core 100.
[0045] At the same time, the limiting groove 1111 is opened on the bottom wall of the first accommodating groove 111, and the limiting protrusion 1221 is arranged on the outer circumferential wall of the second main body 122. In this way, on the one hand, it can avoid the technical problem that the thickness of the outer shell 110 is reduced and the strength of the outer shell 110 is reduced due to the opening of the limiting groove 1111 on the side wall of the first accommodating groove 111, thereby effectively improving the strength of the outer shell 110 and reducing the probability of damage to the outer shell 110.
[0046] On the other hand, the first main body portion 121 and the limiting protrusion 1221 are located at different positions in the axial direction of the shell 110, which effectively improves the space utilization inside the shell 110 and avoids the technical problem that the first main body portion 121 and the limiting protrusion 1221 are located at the same position in the axial direction of the shell 110, resulting in low space utilization inside the shell 110.

[0050] In this embodiment, by arranging the center lines of the first accommodating groove 111, the limiting groove 1111 and the through hole 112 to coincide with each other, and arranging the inner diameter of the limiting groove 1111 to be larger than the inner diameter of the through hole 112 and smaller than the inner diameter of the first accommodating groove 111, the limiting groove 1111 is evenly arranged circumferentially between the first accommodating groove 111 and the through hole 112, so that the thickness of the shell 110 at the position where the limiting groove 1111 is opened is uniform, which is beneficial to improving the overall strength of the shell 110 and further reducing the probability of damage to the shell 110.
[0051] like Figure 4 and Figure 5 As shown, in the above embodiment of the present application, two limiting grooves 1111 are provided, and the two limiting grooves 1111 are spaced apart along the inner circumference of the first receiving groove 111.

[0054] In this embodiment, the second receiving groove 113 is opened on the housing 110, which is in communication with the first receiving groove 111 and is located on the side of the first receiving groove 111 away from the through hole 112, and the valve core body 130 is arranged in the second receiving groove 113, so as to realize the receiving and installation of the valve core body 130. At the same time, by connecting the valve core body 130 with the valve stem sleeve 120, the movable part of the valve core body 130 can follow the valve stem sleeve 120 to rotate synchronously relative to the fixed part of the valve core body 130, so as to realize the opening, closing and flow regulation of the valve core 100.
[0055] like Figure 3 and Figure 4 As shown, in the above embodiment of the present application, the center lines of the second receiving groove 113 and the first receiving groove 111 coincide with each other, and the inner diameter of the second receiving groove 113 is greater than the inner diameter of the first receiving groove 111 .
[0056] In this embodiment, the inner diameter of the second receiving groove 113 is set to be larger than the inner diameter of the first receiving groove 111, so as to accommodate and install the valve core body 130. At the same time, by arranging the center lines of the second receiving groove 113 and the first receiving groove 111 to coincide, the second receiving groove 113 is evenly arranged on the outer circumference of the first receiving groove 111, so that the thickness of the housing 110 at the position where the second receiving groove 113 is opened is uniform, which is beneficial to ensure the overall strength of the housing 110, and further helps to reduce the probability of damage to the housing 110.
[0057] like Figure 1 , Figure 2 and Figure 3 As shown, in any of the above embodiments of the present application, the valve core 100 further includes a valve stem 140 , and the valve stem 140 is connected to an end of the second body portion 122 away from the first body portion 121 .

[0061] An embodiment of the present application also provides a faucet, comprising the valve described in the above embodiment.
[0062] The faucet has the valve in the above-mentioned embodiment, and thus has all the beneficial effects of the valve, which will not be described in detail here.
[0063] In summary, the present application proposes a valve core 100, which includes a housing 110 and a valve stem sleeve 120, wherein the valve stem sleeve 120 includes a first body portion 121 and a second body portion 122 connected to each other, wherein the housing 110 is provided with a first receiving groove 111 and a through hole 112 communicating with the first receiving groove 111, wherein the first body portion 121 is disposed in the first receiving groove 111, and the second body portion 122 is passed through the through hole 112. By providing a limiting groove 1111 on the bottom wall of the first receiving groove 111, and protruding a limiting protrusion 1221 cooperating with the limiting groove 1111 on the outer circumferential wall of the second body portion 122, the rotation angle of the limiting protrusion 1221 is limited under the limiting action of the limiting groove 1111 on the limiting protrusion 1221, thereby realizing the opening, closing and flow regulation of the valve core 100. At the same time, the limiting groove 1111 is provided on the bottom wall of the first receiving groove 111, and the limiting protrusion 1221 is provided on the outer circumferential wall of the second body portion 122.
