Compared with the prior art, the beneficial effects of the present application are:

When using the water quantity control limiting valve of the present application, the limiting valve includes three states: an initial state, a water-passing state and a water-stopping state.

In the initial state of the limit valve, the outlet hollow rod is not subjected to downward force, and the upper end of the plug is in sealing contact with the outlet bearing platform to isolate the outlet cavity from the pre-cavity. When in use, connect the water source to the supply cavity, the water enters the supply cavity, and then enters the pre-cavity through the inlet hollow rod. The body is isolated from the pre-cavity, and the water stops after filling the pre-cavity.

If the limit valve wants to enter the water-passing state, a downward force is applied to the part of the outlet hollow rod located outside the upper end opening of the cylindrical structure, and the outlet hollow rod moves downward under the downward force, and drives the outlet diaphragm to Change the center downward to compress the outlet spring, and at the same time, the outlet hollow rod that moves downward moves downward against the plug. At this time, the limit valve is in the water-passing state, so that the plug is no longer in sealing contact with the outlet bearing platform. At this time, the outlet body and The pre-cavity is connected, and the water in the pre-cavity pours into the outlet cavity, and is transported to the outside of the outlet cavity through the inlet hollow rod. It should be noted that in the water-passing state, when the plug moves downward, it will move downward against the inlet hollow rod, and drive the inlet diaphragm to change its center downward. At this time, the movable bearing platform on the inlet hollow rod will continue to push the inlet spring. Compressed towards the inlet stage, and at this time the end opening of the inlet hollow rod has not yet contacted the closed base. It can be seen from the above that in the water-passing state, the water flows through the supply cavity, the inlet hollow rod, the pre-cavity, the outlet cavity and the outlet hollow rod in sequence, and finally flows out through the outlet hollow rod.

The next step of the limit valve is to change from the water-passing state to the water-stopping state. Specifically, as the downward force applied to the outlet hollow rod increases, the outlet hollow rod continues to move downward, and then moves down against the plug, blocking the plug. The head moves down against the inlet hollow rod, and finally the lower end opening of the inlet hollow rod is in sealing contact with the closed base in the supply cavity, thereby isolating the pre-cavity and the supply cavity. At this time, the water flow can only enter the supply cavity, but cannot Continue to flow to the inlet hollow rod, at this time the limit valve enters the water stop state.

When the downward force exerted on the outlet hollow rod is completely removed, the limit valve quickly returns to the initial state from the water stop state. Specifically, after the downward force exerted on the outlet hollow rod is completely removed, the inlet spring exerts an upward force on the movable bearing platform, so that the inlet hollow rod moves upward, so that the plug collides with the outlet bearing platform to completely The outlet cavity and the pre-cavity are isolated, and the outlet spring also moves the outlet hollow rod upward to the initial state.

It can be seen from the working principle of the above limit valve that the water outlet control of the limit valve only needs to exert increasing force on the outlet hollow rod, and finally remove the applied force, the whole process of water supply and water stop can be completed. In the whole process, the amount of water can be controlled by the downward force on the outlet hollow rod, and the automatic stop of water can be realized, and no circuit is involved. It is completely completed by the structure of the limit valve, which is safe and reliable.

In addition, by reasonably selecting or designing the elastic force of the outlet spring and the inlet spring, it is determined how much downward force is applied to the outlet hollow rod to enter the water stop state, that is, the elastic force of the outlet spring and the inlet spring is determined. The amount of force at the beginning and end of the water-passing state of the limited valve can better control the water output.

When the quantitative water receiving device of the present application is used, the device that exerts downward force on the outlet hollow rod is the water container, and the one-way valve assembly of the water container is inserted into the outlet hollow rod, and the water container itself The weight can trigger the water volume control limit valve to enter the water-passing state. As the amount of water entering the water-holding appliance from the water-volume control limiting valve continues to increase, the weight of the water-containing appliance continues to increase, and the downward force applied to the outlet hollow rod also increases, and finally the water-volume control limiting valve enters the water-stop state. When the water container is taken away from the water control valve, the downward force exerted on the outlet hollow rod is completely removed, and the water control valve quickly returns to the initial state from the water stop state. In this way, when we use water, the quantitative water receiving device can realize quantitative water receiving and automatic closing of water intake, which avoids waste of water when the user is not present, and avoids the overflow of water when the user is not on site. cause other losses.

According to the first aspect of the present application, referring to FIGS. 1 and 2 , a water volume control limiting valve is first provided, which includes a cylindrical structure 10 opened at the upper and lower ends, an outlet hollow rod 20 , an outlet spring 30 , a front movable rod 40 , an inlet Spring 50 and supply cavity 60 .

The inner cavity of the cylindrical structure 10 includes an outlet cavity 11 and a pre-cavity 12 which are connected in sequence from top to bottom. An outlet bearing platform 111 is provided at the connection between the outlet cavity 11 and the pre-cavity 12. An entrance bearing platform 121 is provided at the entrance of the cavity 12 .

The outlet hollow rod 20 is inserted into the outlet cavity 11 from the upper end opening of the cylindrical structure 10 , and the outer wall of the outlet hollow rod 20 and the upper end opening of the cylindrical structure 10 are sealedly connected through the outlet diaphragm 112 , and the outlet diaphragm 112 follows the outlet hollow rod 20 . The up and down movement of the shaft produces deformation in a predetermined range, and the outlet hollow rod 20 communicates with the outlet cavity 11 and the outside of the upper end opening of the cylindrical structure 10 .

The outlet spring 30 is sleeved on the outlet hollow rod 20 and is arranged between the outlet bearing platform 111 and the outlet diaphragm 112. The outlet spring 30 exerts a force away from each other on the outlet diaphragm 112 and the outlet bearing platform 111, that is, the outlet hollow The rod 20 exerts a force for upward movement.

The front movable rod 40 includes an inlet hollow rod 41 and a plug 42. The inlet hollow rod 41 is inserted into the front cavity 12 from the lower end opening of the cylindrical structure 10, and the outer wall of the inlet hollow rod 41 passes through the lower end opening of the cylindrical structure 10. The inlet diaphragm 122 is sealed and connected, and the inlet diaphragm 122 follows the up and down movement of the inlet hollow rod 41 to produce a predetermined range of deformation. The end is connected with the end of the inlet hollow rod 41 located in the front cavity 12 , the upper end of the plug 42 is connected with the outlet hollow rod 20 , and the upper end of the plug 42 is used to interfere with the outlet bearing platform 111 to completely isolate the outlet cavity 11 and the pre-cavity 12; the outer wall of the connection between the inlet hollow rod 41 and the plug is surrounded by a movable bearing platform 411.

The inlet spring 50 is sleeved on the inlet hollow rod 41 and is arranged between the movable bearing platform 411 and the inlet bearing platform 121. The inlet spring 50 exerts a force away from each other on the inlet bearing platform 121 and the movable bearing platform 411, that is, the inlet hollow The rod 41 exerts a force for upward movement.

The supply cavity 60 is connected to the lower end opening of the cylindrical structure 10, and a closed base 61 is arranged in the supply cavity 60. The closed base 61 corresponds to the end of the inlet hollow rod 41 located outside the lower end opening of the cylindrical structure 10; When the rod 41 moves down to contact with the closed base 61, the end opening of the inlet hollow rod 41 is sealed by the closed base 61 to completely isolate the pre-cavity 12 and the supply cavity 60; the supply cavity 60 is connected to an external water source.

When using the water quantity control limiting valve of the above embodiment, the limiting valve includes an initial state, a water supply state and a water stop state. The following is a detailed development of the entire water connection principle of the limit valve from the initial state to the water-passing state, from the water-passing state to the water-off state, and from the water-off state to the initial state:

1) In the initial state of the limiting valve, the outlet hollow rod 20 is not subjected to downward force. At this time, the upper end of the plug 42 is in sealing contact with the outlet bearing platform 111 to isolate the outlet cavity 11 and the pre-cavity 12. When in use, the water source is connected to the supply cavity 60, the water enters the supply cavity 60, and then enters the pre-cavity 12 through the inlet hollow rod 41. After the water enters the pre-cavity 12, because the upper end of the plug 42 and the The outlet bearing platform 111 is in sealing contact to isolate the outlet chamber 11 from the pre-cavity 12 , and stops after the water fills the pre-cavity 12 .

2) If the limiting valve wants to enter the water-passing state, a downward force is applied to the part of the outlet hollow rod 20 located outside the upper end opening of the cylindrical structure 10, and the outlet hollow rod 20 moves downward under the downward force, and The outlet diaphragm 112 is driven to change its center downward to compress the outlet spring 30, and the outlet hollow rod 20 that moves downward moves downward against the plug 42. At this time, the limiting valve is in a water-passing state, so that the plug 42 no longer bears the load on the outlet. The stage 111 is in sealing contact. At this time, the outlet cavity 11 and the pre-cavity 12 communicate with each other. The water in the pre-cavity 12 pours into the outlet cavity 11 and is transported to the outside of the outlet cavity 11 through the inlet hollow rod 41 . It should be noted that in the water-passing state, when the plug 42 moves downward, it will move downward against the inlet hollow rod 41 and drive the inlet diaphragm 122 to change its center downward. At this time, the movable bearing platform 411 on the inlet hollow rod 41 will move downward. The inlet spring 50 will continue to be compressed toward the inlet bearing platform 121 , and at this time, the end opening of the inlet hollow rod 41 is not yet in contact with the closed base 61 . It can be seen from the above that in the water-passing state, the water flows through the supply cavity 60 , the inlet hollow rod 41 , the pre-cavity 12 , the outlet cavity 11 and the outlet hollow rod 20 in sequence, and finally flows out through the outlet hollow rod 20 .

3) The next step of the limiting valve is to switch from the water-on state to the water-off state. Specifically, as the downward force applied to the outlet hollow rod 20 increases, the outlet hollow rod 20 continues to move downward, and then bears the plug. 42 moves down, the plug moves down against the inlet hollow rod 41, and finally the lower end opening of the inlet hollow rod 41 is in sealing contact with the closed base 61 in the supply cavity 60, thereby isolating the pre-cavity 12 from the supply cavity 60. At this time, the water flow can only enter the supply cavity 60, but cannot continue to flow to the inlet hollow rod 41. At this time, the limiting valve enters the water stop state.

4) When the downward force exerted on the outlet hollow rod 20 is completely removed, the limiting valve quickly returns to the initial state from the water cutoff state. Specifically, after the downward force exerted on the outlet hollow rod 20 is completely removed, the inlet spring 50 exerts an upward force on the movable bearing platform 411 to move the inlet hollow rod 41 upward, so that the plug 42 and the outlet are loaded The stage 111 interferes to completely isolate the outlet cavity 11 and the pre-cavity 12, and the outlet spring 30 also moves the outlet hollow rod 20 upward to the initial state.

It can be seen from the working principle of the above limit valve that the water outlet control of the limit valve only needs to exert increasing force on the outlet hollow rod 20, and finally remove the applied force to complete the whole process of water supply and water stop. In the whole process, the amount of water output can be controlled completely by the downward force on the outlet hollow rod 20, and the automatic stop of water receiving can be realized, and no circuit is involved.

In addition, by reasonably selecting or designing the elastic forces of the outlet spring 30 and the inlet spring 50, it is determined how much downward force is exerted on the outlet hollow rod 20 to enter the water-stop state, that is, through the force of the outlet spring 30 and the inlet spring 50. The elastic force determines the amount of force at the beginning and end of the water-passing state of the limited valve, so as to better control the water output.

In one embodiment, the closed base 61 can be made of soft materials such as rubber, so that the inlet hollow rod 41 and the closed base 61 have better contact and sealing effect.

In one embodiment, referring to FIG. 1 , the upper end of the hollow inlet rod 41 is provided with a cylindrical base 421 concentrically fitted with the lower end of the plug 42 , and the lower end of the plug 42 can slide up and down in the cylindrical base 421 . A jack-up spring 43 is arranged between the plug 42 and the cylindrical base 421 , the jack-up spring 43 is sleeved on the plug 42 , and the jack-up spring 43 exerts a force away from each other on the plug 42 and the cylindrical base 421 , that is, the jacking spring 43 exerts an upward movement force on the plug 42 . As explained above, the inlet spring 50 exerts an upward force on the inlet hollow rod 41, and then seals the outlet carrying platform 111 against the plug 42. Here, the second lifting force is further exerted by the lifting spring 43, so that the The sealing between the plug 42 and the outlet bearing platform 111 is tighter, and the speed of the return of the plug 42 is faster.

In one embodiment, referring to FIG. 1 , the pre-cavity 12 includes an intermediate cavity 13 and an inlet cavity 14 that are connected in sequence from top to bottom, and a limit is provided at the junction of the intermediate cavity 13 and the inlet cavity 14 For the bearing platform 131 , the inner diameter of the limiting bearing platform 131 is smaller than the outer diameter of the movable bearing platform 411 , and the limiting bearing platform 131 restricts the movable bearing platform 411 to continue to move upward. The cylindrical base 421 is installed at the junction of the intermediate cavity 13 and the inlet cavity 14 , and the lower surface of the cylindrical base 421 is flush with the limit bearing platform 131 . This is equivalent to increasing the distance that the plug 42 moves down along the cylinder base 421 when the plug 42 moves down, and the bottom end of the plug 42 moves to the bottom end of the cylinder base 421 to push against the inlet hollow rod. 41's move down. It can be seen from this that the downward force not only needs to overcome the elastic force of the outlet spring 30 and the inlet spring 50 , but also needs to overcome a certain elastic force of the jacking spring 43 . Therefore, by reasonably selecting or designing the elastic forces of the outlet spring 30, the inlet spring 50 and the jacking spring 43, the downward force required for the start and end of the water-passing state of the limited valve can be flexibly adjusted, thereby realizing the water output of the limited valve.

The inner diameter of the through hole enclosed by the inlet bearing platform 121 matches the outer diameter of the inlet hollow rod 41 . The inlet diaphragm 122 is located on the lower side of the inlet bearing platform 121 .

As the amount of water entering the water storage device 100 from the water volume control limiting valve continues to increase, the weight of the water storage device 100 continues to increase, and the downward force corresponding to the outlet hollow rod 20 also increases. Finally, the water volume control limiting valve enters the stop water state.
