Description

Technical Field

[0001] The invention relates to a valve device. Background Art

[0002] The existing water channel switching mechanism generally uses a water distribution plate for rotational switching, so that the water flow is directed to different water outlets. With this type of design, the water distribution plate is subject to large wear and friction when rotating. Especially when the water pressure is high, the water pressure on the water distribution plate will seriously hinder the rotation and switching, greatly affecting the user experience. Moreover, since the water distribution plate is cyclically rotating, the sizes of different water distribution ports need to be basically the same to ensure that they can be sealed at any position of the water distribution plate, which greatly limits the diversified design of the switching mechanism. There are limitations in shape, valve volume, and switching force, and it is impossible to achieve better splash effects for different functional water at different flow rates. Summary of the invention

[0003] In order to solve the above technical problems, an object of the present invention is to provide a valve device.

[0007] In the embodiment of the present invention, the end of the pushing body is provided with a first abutment portion and a second abutment portion with a height difference; as the pushing body moves axially, the first abutment portion and the second abutment portion push different valves in sequence.

[0008] In the embodiment of the present invention, an inclined surface is provided between the first abutting portion and the second abutting portion; during the resetting movement of the valve, the inclined surface enables the first abutting portion to switch from one valve to another valve.

[0010] In an embodiment of the present invention, a mating inclined surface is arranged between two adjacent mating grooves. After the pushing body moves circumferentially relative to the mating groove, the second ratchet tooth can cooperate with the mating inclined surface to make the pushing body move circumferentially again, so that the second ratchet tooth is transferred from one mating groove to another mating groove adjacent to it. The pushing body is also connected with a reset spring, and the reset spring can drive the pushing body to move toward the actuating body.

[0011] In an embodiment of the present invention, an arc-shaped matching position is provided on the valve, and the arc-shaped matching position on each valve is arranged in a ring shape.

[0012] In the embodiment of the present invention, a guide groove is further provided in the valve seat, and a guide sheet which can cooperate with the guide groove is provided on the valve, so that the valve can stably open or close the water outlet.

[0013] In the embodiment of the present invention, a boosting inclined plane is further provided on the stabilizing body, and the boosting inclined plane can cooperate with the valve so that the valve pushes the stabilizing body to rotate during the resetting movement.

[0014] In an embodiment of the present invention, the valve is further connected to a spring capable of returning the valve to a direction away from the pushing direction of the pushing body.

Therefore, the features defined as "first" and "second" may explicitly or implicitly include one or more of the features. In the description of the present invention, the meaning of "plurality" is two or more, unless otherwise clearly and specifically defined.

[0028] In the present invention, unless otherwise clearly specified and limited, the terms "installed", "connected", "connected", "fixed" and the like should be understood in a broad sense, for example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection or an indirect connection through an intermediate medium, it can be the internal connection of two elements or the interaction relationship between two elements.

A first feature being "below", "below" and "below" a second feature includes the first feature being directly below and obliquely below the second feature, or simply indicates that the first feature is lower in level than the second feature.

[0030] With reference to the drawings of the specification, a valve device comprises a valve seat 10 having a water-dividing chamber 11, wherein the valve seat is provided with at least two matching valves 20 and a water outlet 12, and an inlet 18 leading to the water-dividing chamber, water flows from the inlet to the water-dividing chamber and then flows out through the water outlet, the valve is capable of moving relative to the valve seat, and its movement can open or close the water outlet of the valve seat, that is, the valve can block the water outlet to achieve water shut-off; it also comprises a switching device, which comprises: 1. a driving body configured to move in an axial direction to move the valve; 2. a stabilizing body configured to stabilize the valve in an open or closed water outlet state at different stable positions, the stable position being the position where the stabilizing body stays on the valve seat after the switching of the switching device ends, the position can be multiple, and can be: it also comprises a matching driving body 30 and a stabilizing body 40, the driving body and the stabilizing body can rotate synchronously relative to the valve seat, the driving body can move axially A relative to the stabilizing body and the valve seat, and also That is, the stabilizing body can only rotate, while the pushing body can rotate and move; the stabilizing body can hold the valve so that the corresponding water outlet is in an open or closed state. When the water outlet is located above the valve, the water outlet is in a closed state when the stabilizing body holds the valve, and when the water outlet is located below the valve, the water outlet is in an open state when the stabilizing body holds the valve; the 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 hold the other valve, or it can hold the two valves together to open the two water outlets and discharge mixed water flows; the movement of the valve on the valve seat can open or close the water outlet. In one embodiment, the valve can perform a lifting motion in the valve seat along a trajectory line parallel to the axial direction to open or close the water outlet, or it can perform a flipping motion, and at the same time, the lifting and lowering of the valve and one end of the water outlet can be realized to control the water outlet switch of the water outlet. In simple terms: the pushing body can move axially relative to the stabilizing body, and the movement of the pushing body can drive the stabilizing body to switch between different stable positions to achieve the movement of different valves, and the different stable positions of the stabilizing body are distributed circumferentially.

[0031] Preferably, the stabilizing body can support one valve, or: the stabilizing body can support two valves at the same time, that is, water can be discharged from a single outlet, or water can be discharged from two outlets. Of course, one valve can be omitted. At this time, the stabilizing body will not support the valve, and the overall water-closed state will be achieved. In other words, the valves are distributed in a ring in the water-dividing chamber, and a valve position can be omitted. No water outlet is made at this position, so that the stabilizing body is in a water-closed state as a whole when it is in this position. Please refer to the attached figure of the specification Figure 8 .

[0032] Furthermore, the end of the pushing body is provided with a first abutment portion 31 and a second abutment portion 32 with a height difference. With the axial movement of the pushing body, the first abutment portion and the second abutment portion push different valves in sequence; in one embodiment, the first abutment portion is located above the second abutment portion; with the axial movement of the pushing body, the first abutment portion and the second abutment portion can lift the valves in sequence. When in use, the first abutment portion first lifts the corresponding valve, and when it rises to a certain height, the second abutment portion abuts and cooperates with another valve. Only then can the two valves be lifted at the same time, and finally multiple valves can be lifted together. At this time, the valve that is lifted first can be depressurized along with the water flow in the water diversion chamber, which can reduce the subsequent required force.

[0033] In one embodiment, an inclined surface 33 is provided between the first abutting portion and the second abutting portion; during the resetting movement of the valve (or when the valve moves downward in the figure), the inclined surface enables the first abutting portion to move from one valve to another valve, and when the actuating body unloads force, most (or all) valves move downward, and the effect of the inclined surface can prevent the valve from falling too fast; if there is no inclined surface, the vertical surface between the first abutting portion and the second abutting portion will abut between the two valves, limiting the rotation of the stabilizing body and rendering the overall function ineffective. If there are three valves, the functions realized may be: valve 1 opens → valve 2 opens → valve 3 opens → valve 1 opens, and so on ... Figure 4 , Figure 5 .

[0034] In another embodiment, that is, when mixing water, because two valves need to be lifted up, the above-mentioned inclined surface does not need to be provided. For example, if there are three valves, the functions implemented are: valve 1 opens → valve 1 and valve 2 opens → valve 2 opens → valve 2 and valve 3 opens → valve 3 opens → valve 3 and valve 1 opens → valve 1, and repeats the process. Please refer to the attached figure of the specification. Figure 6 , Figure 7 .

[0035] Furthermore, the switching device also includes an actuating body 50, which can extend out of the valve seat, and a first ratchet 51 is arranged on the outer periphery of the actuating body, and a second ratchet 34 that can cooperate with the first ratchet is arranged on the pushing body, and a matching groove 13 is also arranged in the valve seat, when the second ratchet is in the matching groove, the pushing body moves axially along the actuating body; when the second ratchet is disengaged from the matching groove, the matching of the first ratchet and the second ratchet can enable the pushing body to move circumferentially; in one use of the present invention, the first ratchet and the second ratchet can be connected to the matching groove, so that the first ratchet and the second ratchet can only move axially in the matching groove, and the rotation is restricted, thereby realizing the axial movement of the actuating body and the pushing body, when the second ratchet is disengaged from the matching groove, the matching of the first ratchet and the second ratchet can enable the pushing body to rotate, and at this time the rotation restriction of the second ratchet is released, so that the pushing body can rotate, and the first ratchet of the actuating body can also not be disengaged from the matching groove, so that the actuating body can only move axially. When the pushing body is lifted by the actuating body, the pushing body first moves axially and then rotates; a matching bevel 14 is provided between two adjacent matching grooves, and after the pushing body rotates relative to the matching groove, the second ratchet can cooperate with the matching bevel, so that the pushing body moves circumferentially again, and the second ratchet is transferred from one matching groove to another matching groove adjacent thereto; the pushing body is also connected with a return spring, and the return spring can drive the pushing body to move toward the actuating body; it can also be: the second ratchet can cooperate with the matching bevel, and at this time the second ratchet is located above the matching bevel, when the actuating body is released, the pushing body moves downward, so that the second ratchet cooperates with the matching bevel guide, so that the pushing body rotates again and falls into another matching groove, so that the second ratchet is transferred from one matching groove to another matching groove adjacent thereto; the pushing body is also connected with a return spring 35, and the return spring can drive the pushing body to move toward the actuating body, and such a mechanism forms a switching structure similar to a ballpoint pen.

[0036] The pusher and the stabilizer can act on the lower end face of the valve to form an abutting fit. Preferably, the valve is provided with an arc-shaped fit position 21, and the arc-shaped fit positions on each valve are arranged in a ring. The pusher and / or the stabilizer can be inserted into the arc-shaped fit position, and the pusher and / or the stabilizer abuts against the arc-shaped fit position, so that the corresponding valve is stabilized in an open or closed water outlet state. In other words, the stabilizer and the pusher can be arranged in the same ring or in different rings, so that the corresponding valve is lifted up, and its corresponding water outlet is in an open state. The arc-shaped fit position can be an arc shape, and the arc-shaped fit position can not only form a guiding effect, but also ensure the stability of the valve in motion. A guide groove 15 is also provided in the valve seat, and a guide sheet 22 that can cooperate with the guide groove is provided on the valve, so that the valve can stably open or close the water outlet, and the valve can perform lifting and lowering movements, which can also increase the guidance and stability of the valve movement.

[0037] Furthermore, the stabilizing body is also provided with a boosting inclined plane 41, which can be connected with the valve so that the valve can push the stabilizing body to rotate during the reset movement, or push the stabilizing body to rotate when the valve descends. Taking three valves as an example, when the stabilizing body is against valve 1, the other side of the stabilizing body (located on the other side of the boosting inclined plane) can be against valve 2. When the actuating body is pushed, the first abutting part first lifts up valve 2, and valve 1 and the stabilizing body do not move. When the heights of valves 1 and 2 are almost the same, the stabilizing body and the pushing body begin to rotate, so that the stabilizing body can move toward valve 2 and hold up valve 2. During this process, the second abutting part can lift up valve 3, and then the actuating body is released, and the stabilizing body and the pushing body continue to rotate. Valve 1 begins to reset and move downward, and valve 1 can just act on the boosting inclined plane to help and drive the stabilizing body and the pushing body to rotate.

[0038] Furthermore, the valve is also connected to a spring 23 that can reset the valve away from the pushing direction of the pushing body, or in other words: the valve is also connected to a spring 23 that can move the valve toward the water outlet, and the valve is also provided with a sealing ring 24 that can cooperate with the water outlet, which can improve the sealing effect.

[0039] More specifically, the present invention is provided with a matching groove and a matching inclined surface on the valve seat; the actuator is axially movable in the matching groove, and it only moves axially but does not rotate; the second ratchet of the pusher is provided in the matching groove of the valve seat, and both have a rotation limit. When the pusher is disengaged from the matching groove, the rotation limit is released, and the pusher can rotate. The pusher abuts against the reset spring, and when pushed by the actuator, two movement stages are generated. In movement stage 1, the pusher moves axially along the matching groove. When the second ratchet is disengaged from the matching groove and loses the rotation limit, the pusher partially rotates under the cooperation of the first ratchet and the second ratchet. In movement stage 2, under the action of the first spring and the matching inclined surfaces, a spiral descending movement occurs, and after rotating a certain angle, the second ratchet falls back into another matching groove. During this stage 2, the driving force on the actuator is removed. The stabilizing body and the pusher have a rotation limit, and can only undergo axial displacement relative to each other. In the first stage of the movement of the pusher, the stabilizing body does not move at first, and then rotates at a small angle; in the second stage of the movement, the stabilizing body rotates circumferentially under the drive of the pusher, and the stabilizing body moves only in the limited area of ​​the arc-shaped matching position of the valve. Each valve has a degree of freedom on the axis and can open or close its corresponding water outlet. After the movement is completed, the valve whose matching surface is against the stabilizing body opens or closes the water outlet, and the other valves close or open their corresponding water outlets under the action of the second spring or water pressure. The stabilizing body is arranged between the valve seat and the matching surface of the valve, and the stabilizing body moves only in the limited area of ​​the arc-shaped matching position of the valve. The pusher is provided with two abutting parts with a step distribution, and in the first stage of the movement, there is a sequence of abutting against the matching surfaces of each valve (that is, the matching surfaces of the valve and the pusher and / or the stabilizing body, which can be the bottom of the arc-shaped matching position). Opening the valves in sequence helps to reduce the influence of water pressure during the switching process and reduce the required driving force. Setting the step distribution is the optimal solution, and the stage distribution may not be set. The valve seat and the valve are arbitrarily provided with guide grooves or guide ribs, respectively, to ensure the stability of the movement of the valve opening or closing in the axial direction. The guide mechanism can also be set at other positions, see the mixed water embodiment: guide grooves or guide ribs are arbitrarily set on the valve and the pusher. The stabilizing body can be provided with a boosting inclined plane, and the pressure drop of the last opened valve during the falling process is on the boosting inclined plane, making it easier for the stabilizing body to rotate and switch to the next position.

[0040] In one use, when the next valve to be opened is initially closed, the valve has a rotation restriction on the stabilizing body. The rotation restriction can only be released when the pusher pushes the mating surfaces of the two valves opened before and after to be flush or the mating surfaces are on the stabilizing body.

[0041] In conjunction with the mixed water embodiment: each valve is provided with a matching surface and an arc-shaped matching position, each matching surface and arc-shaped matching position is distributed circumferentially around the rotation axis, and the stabilizing body moves in the arc-shaped matching position.

[0042] Motion state: Pushing the actuator causes the pusher to first move on the axis, then spiral downward, and then fall back onto the valve seat after rotating a certain angle. The stabilizing body is driven by the pusher to rotate circumferentially and rotate to the bottom of the adjacent valve mating surface. The stabilizing body abuts against the mating surface of the adjacent valve to prevent it from closing the corresponding water outlet on the valve seat. The remaining valves whose mating surfaces are not abutted by the stabilizing body fall back onto the valve seat under the action of the spring or water pressure, closing the corresponding water outlet.

[0043] The actuating member moves upward, the pushing body moves upward, and the stabilizing body does not move; after the pushing body and the stabilizing body are released from the rotation limit (that is, the second ratchet moves away from the matching groove); when the force on the actuating member is removed, the pushing body spirals down, and the stabilizing body rotates a certain angle accordingly.

[0044] When the initial state is mixed water, that is, the two valves are lifted up, and the initial state of the valve to be opened next time is open, the valve to be opened next time is any valve in the mixed water. At this time, the valve has no rotation restriction on the stabilizing body (because the matching surfaces of the two valves are flush and are pushed against by the stabilizing body). When the initial state is independent water, the initial state of the valve to be opened next time is closed, and the valve has rotation restriction on the stabilizing body. The rotation restriction can only be released after the pusher pushes the matching surfaces of the two valves opened before and after to be flush (the matching surfaces are located above the stabilizing body).

[0045] In the present invention, the position of the water outlet on the valve seat can be reversed, that is, at the upper end or lower end of the valve. The embodiment shown in the figure is that the valve is located at the upper end of the water outlet, so that when the valve is lifted up, the water outlet is in a water-passing state; when the valve is located at the lower end of the water outlet, the valve is held up by the stabilizing body and the water outlet is in a closed state. The valve can be set to perform a flipping movement in the valve seat, so that one end of it flips up and down, and realizes up and down movement to open or close the water outlet.

[0046] The above description shows and describes the preferred embodiments of the present invention. As mentioned above, it should be understood that the present invention is not limited to the form disclosed herein, and should not be regarded as excluding other embodiments, but can be used in various other combinations, modifications and environments, and can be modified within the scope of the invention concept described herein through the above teachings or the technology or knowledge of the relevant field.
