[0030] With reference to the accompanying drawings, a valve device comprises a valve seat 10 having a water distribution chamber 11, at least two cooperating valves 20 and a water outlet 12 arranged in the valve seat, and an inlet 18 leading to the water distribution chamber, water flowing from the inlet to the water distribution chamber and then out through the water outlet, the valve being movable relative to the valve seat, the movement of which opens or closes the water outlet of the valve seat, that is, the valve can block the water outlet to achieve water closing; and a switching device, which comprises: 1, a pushing body configured to move in the axial direction to move the valve; 2, a stabilizing body configured to stabilize the valve in an open or closed state of the water outlet in different stable positions, which can be the end of switching of the switching device, the position where the stabilizing body stops in the valve seat, which can be multiple, which can be: further comprising a cooperating pushing body 30 and a stabilizing body 40, the pushing body and the stabilizing body can rotate synchronously relative to the valve seat, the pushing body can move axially A relative to the stabilizing body and the valve seat, that is, the stabilizing body can only rotate, and the pushing body can rotate and move; the stabilizing body can push against the valve to make the cooperating water outlet open or close, when the water outlet is above the valve, the water outlet is in a closed state when the stabilizing body pushes against the valve, and when the water outlet is below the valve, the water outlet is in an open state when the stabilizing body pushes against the valve; axial movement of the pushing body can push the valve to move, so that the stabilizing body can move between the valves, or in other words; the stabilizing body can move from one valve to another valve and push against the other valve, or it can push against both valves to open both water outlets to allow mixed water to flow out; movement of the valve in the valve seat can open or close the water outlet, in an embodiment, the valve can move up and down in the valve seat along a trajectory parallel to the axial direction, thereby opening or closing the water outlet, or it can also perform a flip motion, which can also achieve the lifting of the valve and the water outlet at one end to control the opening and closing of the water outlet. In simple terms: the pushing body can move axially relative to the stabilizing body, the movement of the pushing body can drive the stabilizing body to switch between different stable positions to move different valves, and the different stable positions of the stabilizing body are distributed circumferentially.

[0031] Preferably, the stabilizing body can push against one valve, or: the stabilizing body can push against two valves at the same time, that is, it can perform single water outlet water, or it can also achieve two water outlets for water, of course, it can also have one less valve, at this time the stabilizing body will not push against the valve to achieve the state of overall water closing, that is, the valves are arranged in a ring shape in the water distribution chamber, and one position of the valve can be omitted to make the stabilizing body in this position as a whole in the water closing state, which can be referred to the accompanying drawings Figure 8 .

[0032] Further, the end of the pusher is provided with a first abutting part 31 and a second abutting part 32 with height difference, and with the axial movement of the pusher, the first and second abutting parts push different valves in sequence; in an embodiment, the first abutting part is above the second abutting part; with the axial movement of the pusher, the first and second abutting parts can lift the valves in sequence, and in use, the first abutting part first lifts its corresponding valve, and when rising to a certain height, the second abutting part is in abutting cooperation with another valve, at which time the two valves can be lifted at the same time, and finally multiple valves are lifted at the same time, at which time the valve lifted first can be relieved of pressure with the water flow in the water distribution cavity, and the required force can be reduced.

[0033] In an embodiment, a slope 33 is arranged between the first abutting part and the second abutting part; during the reset movement of the valve (which can also be when the valve in the drawing moves downward), the slope can make the first abutting part move from one valve to another valve, and when the actuator is unloaded, most (or all) valves move downward, and the action of the slope can prevent the valve from descending too fast; if there is no slope, the vertical surface between the first abutting part and the second abutting part will abut between the two valves, which limits the rotation of the stabilizer, and makes the overall function fail. For example, if there are three valves, the functions realized can be: valve 1 is opened → valve 2 is opened → valve 3 is opened → valve 1 is opened, and so on, which can be referred to the drawings in the specification Figure 4 、 Figure 5 .

[0034] In another embodiment, that is, when mixing water, because two valves need to be lifted, the above-mentioned slope is not needed, for example, if there are three valves, the functions realized can be: valve 1 is opened → valve 1 and valve 2 are opened → valve 2 is opened → valve 2 and valve 3 are opened → valve 3 is opened → valve 3 and valve 1 are opened → valve 1 is opened, and so on, which can be referred to the drawings in the specification Figure 6 、 Figure 7 .

[0035] Further, the switching device further comprises an actuating body 50 which can extend out of the valve seat, a first ratchet 51 is arranged on the periphery of the actuating body, a second ratchet 34 which can cooperate with the first ratchet is arranged on the pushing body, and a cooperation groove 13 is further arranged in the valve seat, when the second ratchet is in the cooperation groove, the pushing body moves along the axial direction of the actuating body, when the second ratchet is separated from the cooperation groove, the cooperation between the first ratchet and the second ratchet can make the pushing body move in the circumferential direction, in the use of the utility model, the first ratchet and the second ratchet can be connected with the cooperation groove, so that the first ratchet and the second ratchet can only move in the axial direction in the cooperation groove, and the rotation is limited, the axial movement of the actuating body and the pushing body is realized, when the second ratchet is separated from the cooperation groove, the cooperation between the first ratchet and the second ratchet can make the pushing body rotate, at this time, the rotation limitation of the second ratchet is released, so that the pushing body can rotate, and the first ratchet of the actuating body can still not be separated from the cooperation groove, so that the actuating body only moves in the axial direction, when the pushing body is lifted by the actuating body, the pushing body first moves in the axial direction and then rotates, cooperation inclined surfaces 14 are arranged between adjacent two cooperation grooves, after the pushing body rotates relative to the cooperation groove, the second ratchet can cooperate with the cooperation inclined surface, so that the pushing body moves in the circumferential direction again, so that the second ratchet is transferred from one cooperation groove to another cooperation groove adjacent thereto, the pushing body is further connected with a reset spring, the reset spring can drive the pushing body to move towards the actuating body, or the second ratchet can cooperate with the cooperation inclined surface, at this time, the second ratchet is located above the cooperation inclined surface, when the actuating body is loosened, the pushing body moves downwards, so that the second ratchet cooperates with the cooperation inclined surface, so that the pushing body rotates again and falls into another cooperation groove, so that the second ratchet is transferred from one cooperation groove to another cooperation groove adjacent thereto, the pushing body is further connected with a reset spring 35, the reset spring can drive the pushing body to move towards the actuating body, and the mechanism forms a switching structure similar to a ball pen.

[0036] The pushing body and the stabilizing body can act on the lower end surface of the valve to form abutting cooperation. Preferably, the valve is provided with an arc-shaped cooperation site 21, and the arc-shaped cooperation sites on the valves are arranged in a ring shape. The pushing body and / or the stabilizing body can be inserted into the arc-shaped cooperation site, and the pushing body and / or the stabilizing body abut in the arc-shaped cooperation site, so that the corresponding valve is stabilized in the open or closed water outlet state. That is, the stabilizing body and the pushing body can be arranged in the same ring, or can be arranged in different rings, so that the corresponding valve is lifted, and the corresponding water outlet is in the open state. The arc-shaped cooperation site can be in an arc shape, and the arc-shaped cooperation site can not only form a guiding effect, but also ensure the stability of the valve during movement. The valve seat is further provided with a guide groove 15, and the valve is provided with a guide piece 22 capable of cooperating with the guide groove, so that the valve can stably open or close the water outlet, and the valve can be lifted, so that the guiding and stability of the valve movement can be increased.

[0037] Further, the stabilizing body is further provided with a boosting inclined surface 41, which can be connected with the valve to push the stabilizing body to rotate during the reset movement of the valve, or to push the stabilizing body to rotate when the valve is lowered. Taking three valves as an example, when the stabilizing body pushes against the valve 1, the other side surface of the stabilizing body (located on the other side of the boosting inclined surface) can abut against the valve 2. When the actuating body is pushed, the first abutting portion first lifts the valve 2, and the valve 1 and the stabilizing body do not move. When the height difference between the valve 1 and the valve 2 is almost the same, the stabilizing body and the pushing body start to rotate, so that the stabilizing body can move towards the valve 2 and abut against the valve 2. During this process, the second abutting portion can lift the valve 3, and then the actuating body is released. The stabilizing body and the pushing body continue to rotate, and the valve 1 starts to reset and move downward. The valve 1 can act on the boosting inclined surface to help and drive the stabilizing body and the pushing body to rotate.

[0038] Further, the valve is further connected with a spring 23 capable of resetting the valve away from the pushing direction of the pushing body, or in other words, the valve is further connected with a spring 23 capable of moving the valve away from the water outlet. The valve is further provided with a sealing ring 24 capable of cooperating with the water outlet, so that the sealing effect can be improved.

[0039] The utility model discloses more specifically, the valve seat is provided with the matching groove and the matching slope, the actuating piece can be axially movable and is arranged in the matching groove, and it only moves axially, does not rotate, the second ratchet of pusher is arranged in the valve seat matching groove, and both have rotary limit. When the pusher is separated from the matching groove, the rotary limit is removed, can make the pusher rotate. Pusher abuts the reset spring, when being pushed by the actuating piece, generates two movement stages, movement stage 1, moves axially along the matching groove, when the second ratchet loses the rotary limit and separates from the matching groove, under the cooperation of the first ratchet and the second ratchet, the pusher rotates partially, movement stage 2, under the action of the first spring and each matching slope, the helical descending movement occurs, after rotating a certain angle, the second ratchet falls into another matching groove. Remove the pusher force on the actuating piece in this stage 2 process. The stabilizer and the pusher have rotary limit, can only axially displace each other. In the movement stage 1 of the pusher, the stabilizer does not move first, then rotates a small angle, in the movement stage 2, the stabilizer rotates circumferentially under the drive of the pusher, and the stabilizer only moves in the arc-shaped cooperation position limit area of the valve. Each valve has the freedom of the axis, can open or close the corresponding water outlet. After movement, the matching surface and the valve that the stabilizer abuts open or close the water outlet, and the rest of the valve closes or opens the corresponding water outlet under the action of the second spring or water pressure. The stabilizer is arranged between the valve seat and the valve matching surface, and the stabilizer only moves in the arc-shaped cooperation position limit area of the valve. The pusher is provided with two abutting parts of ladder distribution, in the movement stage 1, the abutting parts abut the valve matching surface (that is, the valve and the pusher and / or the matching surface of the stabilizer, can be the bottom of arc-shaped cooperation position) in the order of sequence. The valves are opened in the order of sequence, which helps to reduce the water pressure influence in the switching process, so that the required pusher force becomes smaller. Setting the ladder distribution is the optimal solution, and the ladder distribution can not be set. The valve seat and the valve are provided with a guide groove or a guide rib respectively, for ensuring the movement stability of the valve in the axial direction. The guide mechanism can also be arranged at other positions, see the mixed water embodiment: the valve and the pusher are provided with a guide groove or a guide rib respectively. The stabilizer can be provided with a boost slope, and the last opened valve is pressed on the boost slope during the falling process, so that the stabilizer is more easily rotated and switched to the next position.

[0040] In a use, when the initial state of the next valve to be opened is closed, the valve has rotary limit to the stabilizer. When the matching surfaces of the two valves opened before and after by the pusher are pushed to be flush or the matching surfaces are above the stabilizer, the rotary limit can be removed.

[0041] Combined with the mixed water embodiment: the valve is provided with a matching surface and an arc-shaped cooperation position, and the matching surface and the arc-shaped cooperation position are distributed circumferentially around the rotation axis, and the stabilizer moves in the arc-shaped cooperation position.

[0042] Motion state: push the actuating member, the pusher first moves in the axis, then moves in the spiral descending motion, rotates a certain angle and falls on the valve seat. The stabilizer is driven by the pusher to rotate circumferentially, and rotates to the lower side of the adjacent valve cooperation surface. The stabilizer abuts against the cooperation surface of the adjacent valve to prevent it from closing the corresponding water outlet on the valve seat. The remaining valves whose cooperation surfaces are not abutted by the stabilizer fall on the valve seat under the action of the spring or water pressure to close the corresponding water outlet.

[0043] The actuating member moves upward, the pusher moves upward, and the stabilizer does not move. The pusher and the stabilizer are separated from the rotation limiting position (that is, the second ratchet moves away from the cooperation groove). When the force on the actuating member is removed, the pusher descends in the spiral, and the stabilizer rotates a certain angle.

[0044] When the initial state is mixed water, that is, both valves are lifted, and the initial state of the valve to be opened next is open, the valve to be opened next is any one of the mixed water valves. At this time, the valve has no rotation limitation on the stabilizer (because the cooperation surfaces of the front and rear valves are flush and are abutted by the stabilizer). When the initial state is independent water, the initial state of the valve to be opened next is closed. At this time, the valve has rotation limitation on the stabilizer. The rotation limitation can be removed when the pusher pushes the cooperation surfaces of the valves opened in the front and rear times to be flush (the cooperation surfaces are located above the stabilizer).

[0045] In the utility model, the water outlet position on the valve seat can be arranged up and down, that is, at the upper end or the lower end of the valve. The embodiment shown in the drawing is that the valve is located at the upper end of the water outlet. When the valve is lifted, the water outlet is in the water passing state. When the valve is located at the lower end of the water outlet, the valve is abutted by the stabilizer, and the water outlet is in the closed state. The valve can be arranged to perform the overturning motion in the valve seat, so that one end of the valve is turned up and down to move up and down to open or close the water outlet.

[0046] The above description shows and describes the preferred embodiments of the utility model. As described above, it should be understood that the utility model is not limited to the form disclosed herein, and should not be considered as excluding other embodiments, but can be used in various other combinations, modifications and environments, and can be modified by the above teaching or related technology or knowledge within the scope of the utility model concept described herein. The modification and change made by the person skilled in the art without departing from the spirit and scope of the utility model should be within the protection scope of the claims attached to the utility model.
