The second adjusting member 234 is provided with a second internal thread 232, the second adjusting member 234 is connected to the fixing base 22 through a thread, meanwhile, the second adjusting member 234 is sleeved in the first adjusting member 233, and a second limiting member 236 is arranged at one end of the second adjusting member 234, which is located in the first adjusting member 233, when the second adjusting member 234 extends out relative to the first adjusting member 233, the second limiting member 236 is used for abutting against the first adjusting member 233 to limit the second adjusting member 234 to be disengaged from the first adjusting member 233. The second adjusting member 234 is retractable relative to the first adjusting member 233, so that the first adjusting member 23 is retractable relative to the pressing member 21, the second adjusting member 234 is retractable relative to the first adjusting member 233, and the fixing base 22 is retractable relative to the second adjusting member 234, thereby increasing the adjusting range of the adjusting member 23 relative to the pressing member 21 and the fixing base 22.

In addition, in other embodiments, when the maximum depth of the adjustment range that can be achieved by the number of the adjustment members 23 is smaller than the depth requirement, the number of the adjustment members 23 may be increased appropriately, for example, the adjustment members 23 may also be provided with a third adjustment member 23 to meet the depth requirement. Similarly, when the minimum depth of the adjusting range that can be achieved by the number of the adjusting members 23 is greater than the depth requirement, the number of the adjusting members 23 can be reduced appropriately, for example, the second adjusting member 234 can be removed to meet the depth requirement.

Referring to fig. 2 and fig. 3, in the present embodiment, a gasket 24 may be further included, where the gasket 24 is configured to be sleeved on the valve core 30 and abut against the fixing seat 22, and when the adjusting element 23 contracts and the length of the adjusting device 20 along the axial direction of the mounting hole 211 is the minimum, the gasket 24 may abut against the adjusting element 23 and the pressing element 21, so as to prevent the adjusting element 23 and the pressing element 21 from approaching the valve core 30, thereby affecting the switching of the opening and closing water passing functions of the valve core 30.

According to the adjusting valve core 10 provided by the embodiment of the application, the adjusting device 20 is arranged on the valve core 30, and the adjusting device 20 is dynamically adjusted, so that the depth requirement of the valve core 30 is met.

When the installation depth of the valve core 30 is smaller than the depth requirement, the adjusting piece 23 of the adjusting device 20 can be adjusted, so that the distance between the pressing piece 21 and the fixing seat 22 is increased, and the depth requirement is met, specifically, the pressing piece 21 and the adjusting piece 23 can be regarded as a whole, the whole formed by the pressing piece 21 and the adjusting piece 23 is extended relative to the fixing seat 22 by rotating the adjusting piece 23, and the depth requirement is met, or the fixing seat 22 is used as a base piece, and the pressing piece 21 and the adjusting piece 23 are rotated, and the depth requirement is met by extending the whole formed by the pressing piece 21 and the adjusting piece 23 relative to the adjusting piece 23 and the fixing seat 22.

Similarly, when the installation depth of the valve core 30 is greater than the depth requirement, the distance between the pressing piece 21 and the fixing seat 22 is reduced by rotating the pressing piece 21 or the adjusting piece 23, so that the depth requirement is met. In addition, when the distance between the pressing member 21 and the fixing seat 22 is minimized but the depth requirement is not yet satisfied, the number of the adjusting members 23 may be appropriately reduced so as to satisfy the depth requirement.

After the adjusting valve core 10 meets the depth requirement, the user presses the key abutted to the adjusting device 20 to drive the adjusting device 20 to move, and the valve core 30 moves through the transmission of force, so that the opening or closing state of the water path is switched.
