Description
Technical Field
The invention relates to a valve core of a water faucet, in particular to a multi-key linkage type water distribution (water outlet channel for distributing water flow) valve core.
Background
The water diversion valve core is used for water diversion during bathing and can control the water flow direction and distribute the water flow. The switching and water diversion of the water diversion valve core can be roughly divided into two types, one is switched in a rotating mode, and the other is switched in a pressing mode.
The current case that divides is mostly two waterways and switches control, when in the application environment of many waterways (being more than two waterways), then needs a plurality of cases that divide to control. The cost of the bathroom faucet is increased, and meanwhile, the operation is inconvenient because the operation ends of the two water distribution valve cores are far away from each other.
Therefore, a multi-button water distributing valve core is invented by some people, and the structure is disclosed in the Chinese utility model patent No. ZL202020034681.4, namely 'a water distributing valve core for a water tap'. The water control valve comprises a valve body, wherein a water inlet and a plurality of water outlets are formed in the valve body, the water outlets are communicated with the water inlet, a water sealing device for opening and closing the valve body is arranged at the water outlets, and the valve body realizes independent water control through the water sealing device. The water sealing device comprises a water sealing part and a spring, the water sealing part is in a T-shaped column shape, the water sealing part is installed in a water sealing device installation hole, the water sealing part is limited by a T-shaped cap and the water sealing device installation hole, the T-shaped column can extend into a water outlet along the water sealing device installation hole, the lower end and the upper end of the T-shaped column are respectively provided with a sealing ring, the lower end of the T-shaped column can be in sealed sleeve joint with the water outlet through the sealing ring, and the upper end of the T-shaped column is in sealed sleeve joint with the water sealing device installation hole through the sealing ring. Go up still to be equipped with switching device on the valve body, switching device includes the button, push rod and rotation piece, the button cup joints in the push rod upper end, the push rod lower extreme is provided with bellied closed angle structure, upward be provided with the slotted hole that supplies push rod axial motion on the valve body, be provided with the spout that matches with the push rod arch on the slotted hole inner wall, be equipped with the inclined plane on the terminal surface of the guide pillar that corresponds with the spout, the push rod is spacing upwards through protruding and slotted hole axial, be provided with bellied rotation foot on the rotation piece, the rotation foot matches with the spout, the up end of rotating the foot is provided with the oblique angle spigot surface, the rotation of rotation piece is realized with the closed angle structure cooperation of push rod to the oblique angle spigot surface.
During the use, press the button of required water sealing, make the push rod promote downwards along the spout axial, bellied closed angle on the push rod contradicts the oblique angle sliding surface that rotates a up end, make to rotate and the axial moves down promotes water sealing spare, it is interior until the lower extreme of water sealing spare extends to the play water, sealing member and the delivery port through water sealing spare lower extreme are sealed, it removes the spout completely to rotate the piece, and contradict through bellied closed angle on the push rod and the oblique angle sliding surface that rotates a up end and make the rotation foot that rotates on the piece rotatory to the one-way inclined plane department of the traveller that corresponds, the spring produces elasticity with water sealing spare relatively, loosen the button, because rotate the one-way inclined plane conflict on foot and the traveller, water sealing spare can't pass through the spring return, realize that the delivery port that corresponds seals water. And pressing the key again to enable the rotating piece to rotate again, enabling the rotating pin on the rotating piece to correspond to the sliding groove, loosening the key, enabling the rotating piece to slide into the groove hole along the sliding groove through the elastic force of the spring, enabling the water sealing piece to move upwards in the axial direction, enabling the lower end of the water sealing piece to be separated from the water outlet, and realizing water outlet of the corresponding water outlet, wherein the above steps are repeated. When water outlet or water sealing of a plurality of water outlets is required to be controlled simultaneously, corresponding keys can be pressed simultaneously.
The advantage of the aforesaid patent is that can carry out independent accuse water to multichannel water route through a valve body. But the independent water control mode has the following defects: in many scenes, although a plurality of water paths are required to be switched, only one water path is required during use, for example, a shower head of a shower room is generally divided into three paths, one path is a shower head, the other path is top spraying, the other path is a faucet, only one path of the three paths of water flows out during switching, and the defect of inconvenient operation exists if the above patent is used, namely, after one path of water is opened, if the other path of water is required to be opened, the front path of water needs to be closed firstly, and then the second path of water needs to be opened.
In summary, the multi-button water diversion valve core can be further improved.
Disclosure of Invention
The first technical problem to be solved by the present invention is to provide a linkage mechanism for a water distribution valve core with a reasonable and compact structural layout, in view of the above-mentioned current state of the art, the linkage mechanism only needs to press one of the plurality of key levers to lock the key lever, and then the former locked key lever will automatically unlock and move upwards.

The outer peripheral wall of the key lever 2 is further provided with a convex guide block 222, and the inner cavity wall of the valve housing 1 is provided with a guide groove 122 for the guide block 222 to slide up and down in the inner cavity wall.
The key lever 2 is composed of an upper lever portion 21 and a lower lever portion 22, and the upper lever portion 21 is sleeved on the upper end of the lower lever portion 22. The upper and lower rod portions 21 and 22 are fitted through non-circular holes so that the upper and lower rod portions 21 and 22 cannot rotate relative to each other.
The working principle and the process of the multi-key linkage type water diversion valve core are as follows:
at the initial position, one of the key rods 2 is in a downward moving position state and is locked, and the corresponding water diversion valve plate 8 below the key rod 2 is in a state of opening the corresponding valve hole 71; other key rods 2 are in an upward moving position state, and the water diversion valve plates 8 corresponding to the lower parts of the other key rods 2 are in initial positions under the action of the third elastic reset structure 10, namely, the water diversion valve plates 8 are in a state of closing the corresponding valve holes 71.
When any unlocked key rod 2 is pressed, the bottom surface 61 of the second stopper 6 corresponding to the key rod 2 and the top surface 321 of the first stopper 32 on the corresponding switch plate 3 push against each other to force the switch plate 3 to rotate, the first stopper 32 on the switch plate 3 corresponding to the locked key rod 2 releases the locking of the previous locked key rod 2, and the key rod 2 is reset to the upward moving position by the first reset elastic member 4. In the initial position state where key lever 2 moves upward, first stopper 32 is located below second stopper 6, and the misalignment between them does not affect the rotation of switching plate 3.
When the key lever 2 is pressed down and moved down to the locking position, the first blocking portion 32 on the key lever 3 is separated from the second blocking portion 6 of the key lever 2, i.e. the first blocking portion 32 is located above the second blocking portion 6, so that the first blocking portion 32 on the reset switching plate 3 blocks and locks the second blocking portion 6 to prevent the key lever 2 from moving up.
The water diversion valve core can open the waterway and close other waterways at the same time by only pressing one key.
