Description

Technical Field

[0001] The utility model relates to the technical field of valve equipment, and particularly relates to a flushing valve kit with a function of quantitative water output. Background Art

[0002] At present, flushing valves have been widely used in modern families and public sanitation facilities. Traditional flushing valves often focus on simple on-off control in design, that is, when the switch is triggered, the piston body in the valve body will be lifted, so that the valve body is opened to be in a flushing state. Although this design meets the basic flushing requirements, it has significant deficiencies in water resource management. Specifically, the existing flushing valves do not have a structure that can support quantitative water output. If the switch remains in the triggered state all the time, the valve body will be in a continuously open state, flushing without limit, resulting in serious water resource waste. In addition to the situation of deliberately continuously triggering the switch by humans, after long-term use, the triggering part in the switch of the flushing valve will also age, resulting in increased friction of the trigger part moving, and it is easy to get stuck. This situation will also cause the valve body to be in an abnormal continuously open state, resulting in water resource waste. Therefore, there is an urgent need for a flushing valve that still has the function of quantitative water output even when the switch is in a continuously open state, to ensure that while meeting the flushing requirements, water resource waste is minimized to the greatest extent. Summary of the Utility Model

[0003] The purpose of the utility model is to provide a flushing valve kit with a function of quantitative water output, and solve the problem that the existing flushing valves do not have a structure that can support quantitative water output, thus easily causing water resource waste.

[0004] The technical solution provided by the utility model is as follows: A flushing valve kit with a function of quantitative water output includes a flushing valve main body, a piston mechanism for opening and closing the flushing valve main body, and a trigger mechanism for triggering the piston mechanism. An upper cavity and a lower cavity are arranged inside the flushing valve main body. An inlet valve port communicating with the upper cavity and an outlet valve port communicating with the lower cavity are opened outside the flushing valve main body. The piston mechanism includes a piston body, a pressure relief swing rod, and a telescopic rod. The trigger mechanism includes a trigger piece. The piston body is movably arranged in the upper cavity. The pressure relief swing rod penetrates through the piston body and protrudes into the lower cavity. The telescopic rod is axially movably connected to the pressure relief swing rod. The trigger piece is movably arranged in the lower cavity and abuts against the telescopic rod.

[0005] When the trigger mechanism is opened, the trigger piece abuts against the telescopic rod to pry the pressure relief swing rod, so that the upper cavity is depressurized in the space above the piston body, driving the piston body to move away from the lower cavity, and opening the flushing valve main body.

[0006] When the toilet valve body is opened, the pressure relief rocker arm is reset and moves with the piston body, while driving the telescopic rod to move, so that the telescopic rod is separated from the abutment of the trigger member until the pressure on the upper side of the piston body and the water inlet valve port is stabilized. The telescopic rod abuts against the trigger member along the radial direction of the trigger member and shrinks relatively to the pressure relief rocker arm along the axial direction to release the interference of the trigger member on the reset of the piston body. At this time, the piston body is reset and the toilet valve body is closed.

[0007] In the toilet flushing valve kit with a quantitative water discharge function as described above, a telescopic clearance cavity arranged axially is provided inside the pressure relief rocker arm, a sliding end is provided on the upper side of the telescopic rod, and the sliding end is movably arranged in the telescopic clearance cavity, so that the lower side rod body of the telescopic rod can be extended or contracted axially relative to the pressure relief rocker arm.

[0010] A flushing valve kit with a quantitative water discharge function as described above also includes a flow regulating mechanism arranged corresponding to the piston mechanism, and the flow regulating mechanism includes an adjusting screw connected to the flushing valve body, an end of the adjusting screw away from the piston body is exposed to the flushing valve body, and an end of the adjusting screw close to the piston body is used to abut the piston body in the upper cavity to adjust the movement stroke of the piston body.

[0011] In the toilet valve kit with quantitative water discharge function as described above, the flow regulating mechanism further comprises a safety cap arranged outside the toilet valve body, and the safety cap is used to surround and cover the end of the regulating screw exposed from the toilet valve body.

[0012] A toilet flushing valve kit with a quantitative water discharge function as described above also includes a check mechanism connected to the toilet flushing valve body, the check mechanism includes a water inlet chamber, a water outlet chamber, and a check piece movably arranged along the vertical direction, the water inlet chamber is connected to the external water supply end, the water outlet chamber is connected to the water inlet valve port, and the check piece is pressed downward to cover the water inlet chamber.

[0016] Compared with the prior art, the present utility model has the following advantages:

[0017] In the flushing valve kit with a function of quantitatively discharging water of the present utility model, a design of adding a telescopic rod is adopted in the piston mechanism. When the telescopic rod extends relative to the pressure relief swing rod, the pressure relief swing rod can be driven to swing through the abutting action of the trigger member, realizing the pressure relief effect to drive the piston body to move upward to open the valve body. At the same time, the telescopic rod is driven to rise until it disengages from the abutment of the trigger member. When the piston body needs to descend and reset, even if the trigger member is in a continuously ejected trigger state, the telescopic rod can first abut against the trigger member and then contract relative to the pressure relief swing rod, so that the piston body can still be normally reset, realizing the effect of quantitatively discharging water and minimizing the waste of water resources to the greatest extent.

DETAILED DESCRIPTION

[0024] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the protection scope of the utility model.

[0025] Example 1: Please refer to the attached Figure 1 To Attachment Figure 5, this embodiment provides a flushing valve kit with a function of quantitatively discharging water, which includes a flushing valve main body 1, a piston mechanism 2 for opening and closing the flushing valve main body 1, and a triggering mechanism 3 for triggering the piston mechanism 2. An upper cavity 11 and a lower cavity 12 are provided inside the flushing valve main body 1. An inlet valve port 111 communicating with the upper cavity 11 and an outlet valve port 121 communicating with the lower cavity 12 are opened on the outside of the flushing valve main body 1. The piston mechanism 2 includes a piston body 21, a pressure relief swing rod 22, and a telescopic rod 23. The triggering mechanism 3 includes a trigger member 31. The piston body 21 is movably arranged in the upper cavity 11. The pressure relief swing rod 22 passes through the piston body 21 and protrudes into the lower cavity 12. The telescopic rod 23 is axially movably connected to the pressure relief swing rod 22. The trigger member 31 is movably arranged in the lower cavity 12 and abuts against the telescopic rod 23 along the radial direction of the telescopic rod 23. When the triggering mechanism 3 is opened, the trigger member 31 abuts against the telescopic rod 23 to pry the pressure relief swing rod 22, so that the upper cavity 11 is depressurized in the space above the piston body 21, driving the piston body 21 to move away from the lower cavity 12, and opening the flushing valve main body 1. After the flushing valve main body 1 is opened, the pressure relief swing rod 22 resets and moves with the piston body 21, driving the telescopic rod 23 to move at the same time, so that the telescopic rod 23 is disengaged from the abutment of the trigger member 31. Until the pressure above the piston body 21 is stabilized at the inlet valve port 111, the telescopic rod 23 abuts against the trigger member 31 along the radial direction of the trigger member 31 and relatively contracts along the axial direction with respect to the pressure relief swing rod 22, so as to relieve the interference of the trigger member 31 on the reset of the piston body 21. At this time, the piston body 21 resets and closes the flushing valve main body 1. In the flushing valve kit with a function of quantitatively discharging water in this embodiment, an additional telescopic rod 23 is designed in the piston mechanism 2. When the telescopic rod 23 extends relative to the pressure relief swing rod 22, it can drive the pressure relief swing rod 22 to swing through the abutting action of the trigger member 31, realizing the pressure relief effect and driving the piston body 21 to move upward to open the valve body. At the same time, the telescopic rod 23 is driven to rise until it is disengaged from the abutment of the trigger member. When the piston body needs to descend and reset, even if the trigger member is in a continuously ejected trigger state, the telescopic rod can first abut against the trigger member and then contract relative to the pressure relief swing rod, so that the piston body can still be normally reset, realizing the effect of quantitatively discharging water and minimizing the waste of water resources.

[0026] An axially arranged telescopic accommodation cavity 221 is provided inside the pressure relief swing rod 22. A sliding end 231 is provided on the upper side of the telescopic rod 23. The sliding end 231 is movably arranged in the telescopic accommodation cavity 221, so that the lower rod body of the telescopic rod 23 can extend or contract axially relative to the pressure relief swing rod 22. By adjusting the height of the telescopic accommodation cavity 221, the telescopic stroke of the telescopic rod 23 can be adjusted.

[0027] Further, preferably, a telescopic pressure relief hole 222 is opened in the telescopic accommodation cavity 221 to balance the air pressure between the telescopic accommodation cavity 221 and the lower cavity 11 when the telescopic rod 23 expands and contracts, facilitating the expansion and contraction of the telescopic rod 23.

[0028] The radial width of the sliding end 231 is greater than the radial width of the lower rod body of the telescopic rod 23. A limit cover 223 is provided at the lower end of the pressure relief swing rod 22. The lower rod body of the telescopic rod 23 is inserted through the limit cover 223, and the sliding end 231 can abut against the limit cover 223 to limit the extension of the telescopic rod 23.

[0029] The flushing valve kit with a function of quantitative water output further includes a flow regulating mechanism 4 arranged corresponding to the piston mechanism 2. The flow regulating mechanism 4 includes an adjusting screw 41 inserted through the flushing valve main body 1. One end of the adjusting screw 41 away from the piston body 21 is exposed outside the flushing valve main body 1. One end of the adjusting screw 41 close to the piston body 21 is used to abut against the piston body 21 in the upper cavity 11 to adjust the moving stroke of the piston body 21. By adjusting the moving stroke of the piston body 21, the flushing flow rate of the flushing valve main body 1 at the valve opening can be adjusted.

[0030] The flow regulating mechanism 4 further includes a safety cap 42 arranged outside the flushing valve main body 1. The safety cap 42 is used to surround and cover one end of the adjusting screw 41 exposed outside the flushing valve main body 1. By adding the safety cap 42, the safety cap 42 is used to protect the exposed part of the adjusting screw 41. This structure can not only prevent the adjusting screw 41 from accidentally twisting due to complex external factors, but also reduce the corrosion effect of the adjusting screw 41 by the external environment.

[0031] The flushing valve kit with a function of quantitative water output further includes a check mechanism 5 connected to the flushing valve main body 1. The check mechanism 5 includes a water inlet cavity 51, a water outlet cavity 52, and a check member 53 movably arranged in the vertical direction. The water inlet cavity 51 is connected to the external water supply end, the water outlet cavity 52 is connected to the water inlet valve port 111, and the check member 53 is pressed downward to cover the water inlet cavity 51. Under the action of gravity, the check member 53 keeps the water inlet cavity 51 sealed until the water flow has a tendency to flow from the water inlet cavity 51 to the water outlet cavity 52, and then the check member 53 will be pushed upward to flow into the water outlet cavity 52. If there is a reverse flow, the water flow will push the check member 53 back to the state of pressing against the water inlet cavity 51 and strengthen the sealing effect of the check member 53. Therefore, the effect of preventing the water flow passing through the check mechanism 5 from generating a reverse flow can be achieved.

[0032] The check mechanism 5 further includes an adjusting sleeve column 54. The check member 53 includes a vertical rod portion 531 and a cover plate portion 532. The adjusting sleeve column 54 is sleeved on the vertical rod portion 531, so that the check member 53 can move up and down axially along the adjusting sleeve column 54. When the water inlet cavity 51 supplies water to the water outlet cavity 52, the water flow pushes the check member 53 open. At this time, the lower end of the adjusting sleeve column 54 can abut against the cover plate portion 532 to limit the upward movement of the check member 53. The adjusting sleeve column 54 can adjust the upward movement stroke of the check member 53, thereby adjusting the flow rate of the water flow passing through the check mechanism 5.

[0033] The flushing valve kit with a quantitative water outlet function further includes an anti-overflow air mechanism 6 provided at the water outlet valve port 121. The anti-overflow air mechanism 6 includes a valve sleeve 61 and a support ring 62. The valve sleeve 61 is arranged along the axial direction of the water outlet valve port 121, and the support ring 62 is used to abut against the water inlet opening of the valve sleeve 61 along the circumferential side. The valve sleeve 61 is made of an elastic material, preferably rubber. The water flow ejected from the flushing valve body 1 will flush open the valve of the valve sleeve 61 and then flow out. When the flushing valve body 1 does not discharge water, the valve of the valve sleeve 61 is in a closed state, which has the function of blocking the reverse-flow water vapor to prevent the odor in the toilet from entering the flushing valve body 1 and causing an overflow situation.

[0034] Preferably, the trigger 31 is rod-shaped. One end of it abuts against the telescopic rod 23 along the radial direction of the telescopic rod 23, and the other end can realize the telescopic trigger of the trigger 31 by setting different styles of switches. The ultimate triggering effect of these switches is to press the trigger 31 in the direction of pressing against the telescopic rod 23, driving the trigger 31 to move axially to trigger the swing of the telescopic rod 23 and drive the swing of the pressure relief swing rod 22.

[0035] Although the embodiments of the present invention have been shown and described, for those of ordinary skill in the art, it can be understood that various changes, modifications, substitutions, and variations can be made to these embodiments without departing from the principle and spirit of the present invention.
