The switching water diversion of the water diversion valve core can be roughly divided into two types, one is switching in a rotary manner and the other is switching in a pressing manner.
Most of the existing water diversion valve cores are switched and controlled by two waterways, and when the existing water diversion valve cores are used in the application environment of multiple waterways (more than two waterways), the water diversion valve cores are required to be controlled. The cost of the bathroom faucet is increased, and meanwhile, the operation ends of the two water diversion valve cores are far away from each other, so that the operation is inconvenient.
For this reason, a multi-key water diversion valve core is invented, and such a structure is disclosed in the chinese utility model patent No. ZL202020034681.4, a water diversion valve core of a faucet. The valve body is provided with a water inlet and a plurality of water outlets, the water outlets are communicated with the water inlet, the water outlets are provided with water sealing devices for opening and closing the valve body, and the valve body realizes independent water control through the water sealing devices.

The upper valve body is further provided with a switch device, the switch device comprises a key, a push rod and a rotating piece, the key is sleeved at the upper end of the push rod, the lower end of the push rod is provided with a convex sharp corner structure, the upper valve body is provided with a slotted hole for axial movement of the push rod, the inner wall of the slotted hole is provided with a sliding groove matched with the protrusion of the push rod, the end face of a guide post corresponding to the sliding groove is provided with an inclined plane, the push rod is axially upwards limited with the slotted hole through the protrusion, the rotating piece is provided with a convex rotating foot matched with the sliding groove, the upper end face of the rotating foot is provided with an oblique angle sliding surface, and the oblique angle sliding surface is matched with the sharp corner structure of the push rod to realize rotation of the rotating piece.
When the water sealing device is used, a key to be sealed is pressed, the push rod is pushed downwards along the axial direction of the sliding groove, the protruding sharp angle on the push rod is abutted against the oblique angle sliding surface of the upper end face of the rotating piece, the rotating piece is enabled to rotate and move downwards axially to push the water sealing piece until the lower end of the water sealing piece extends into the water outlet, the sealing piece at the lower end of the water sealing piece is sealed with the water outlet, the sliding groove is completely removed by the rotating piece, the rotating foot on the rotating piece is enabled to rotate to the corresponding one-way inclined surface of the sliding column by the protruding sharp angle on the push rod and the oblique angle sliding surface of the upper end face of the rotating piece, the spring generates elasticity with the water sealing piece relatively, the key is loosened, and the water sealing piece cannot return through the spring due to the abutting of the rotating foot and the one-way inclined surface on the sliding column, so that water sealing of the corresponding water outlet is realized. Pressing the key again to make the rotating member rotate again, so that the rotating foot on the rotating member corresponds to the position of the chute, loosening the key, enabling the rotating member to slide into the slot hole along the chute by the elasticity of the spring, enabling the water sealing member to axially move upwards, enabling the lower end of the water sealing member to be separated from the water outlet, and realizing water outlet of the corresponding water outlet, thus circulating. When the water outlet or the water sealing of a plurality of water outlets is required to be controlled simultaneously, the corresponding keys can be pressed simultaneously.
The advantage of the foregoing patent is that independent control of water in multiple waterways can be achieved through a valve body. However, the independent water control mode has the following defects: in many scenes, although a plurality of waterways are needed for switching, only one waterway passage is needed when the shower is used, such as a shower head of a shower room, the shower head is generally divided into three paths, one path is a shower head, the other path is a top shower, the other path is a faucet, and only one path of water in the three paths can be discharged when the shower head is switched, if the shower head is used, the other path of water is opened, if the shower head is opened, the other path of water needs to be closed, and then the second path of water needs to be opened.
In summary, the multi-key water diversion valve core can be further improved.
Disclosure of Invention
The first technical problem to be solved by the invention is to provide a linkage mechanism for a water diversion valve core, which has a reasonable and compact structural layout and an emergency unlocking function, aiming at the current state of the art, and the linkage mechanism can automatically unlock and move upwards after only one of a plurality of key levers is pressed down to lock the key lever.
The technical scheme adopted by the invention for solving the first technical problem is as follows: the utility model provides a water diversion is link gear for case which characterized in that: comprises a plurality of key levers;
A first reset elastic piece acting on each key rod and enabling the key rods to have upward reset trend in the axial direction;
An emergency unlocking rod;
The second reset elastic piece is used for acting on the emergency unlocking rod and enabling the emergency unlocking rod to have an upward reset trend in the axial direction;
The switching disc and the third reset elastic piece are acted on the switching disc and enable the third reset elastic piece to have a rotary reset trend in the circumferential direction, a plurality of key holes and an emergency unlocking hole are formed in the switching disc, a key rod is respectively arranged in each key hole in a penetrating mode, the key rods can move up and down in the key holes, and the emergency unlocking rod can move up and down in the emergency unlocking hole;
