[Technical Field]

[0001] This invention relates to the technical field of water circuit control systems, and in particular to a toilet flushing system with delayed control switching. [Background Technology]

[0002] See Figure 1 In existing technologies, if a water circuit control system has two valves, valve A1 and valve B2, they are generally electrically controlled or manually controlled separately during power outages. Manual control is complex for users; furthermore, if there are timing requirements, users cannot accurately control the switching of the two valves. Therefore, a toilet flushing system with delayed control switching is proposed. [Summary of the Invention]

[0003] The purpose of this invention is to solve the problems in the prior art and to propose a toilet flushing system with delayed control switching, which allows manual control of the switching of two valves and meets timing requirements.

[0004] To achieve the above objectives, this invention proposes a toilet flushing system with delayed control switching, including a main water inlet connected to a water source, and outlets A and B connected in parallel to the main water inlet. Valves A and B are respectively connected in series to outlets A and B. The system also includes a manual mechanical delay control mechanism. Valves A and B are respectively provided with a switch control mechanism A and a switch control mechanism B connected to the manual mechanical delay control mechanism. By operating the manual mechanical delay control mechanism, the system can control the opening and closing of valves A and B and the valve opening time according to a timing sequence.

[0005] Preferably, when the manual mechanical delay control mechanism is operated to the position where it has reached its maximum energy storage, valve A is opened first; after the manual mechanical delay control mechanism releases a certain proportion of energy, valve A is closed and valve B is opened; when the manual mechanical delay control mechanism has completed the energy release, valve B is closed.

[0006] Preferably, before the manual mechanical delay control mechanism is operated to the maximum energy storage position, valve A is opened first; when the manual mechanical delay control mechanism is operated to the maximum energy storage position, valve A is closed and valve B is opened; after the manual mechanical delay control mechanism releases a certain proportion of energy, valve B is closed and valve A is opened; when the manual mechanical delay control mechanism has completed energy release, valve A is closed.

[0007] Preferably, when the manual mechanical delay control mechanism is operated to the maximum energy storage position, valve A is opened first; after the manual mechanical delay control mechanism releases a certain proportion of energy, valve A is closed and valve B is opened; after the manual mechanical delay control mechanism releases a certain proportion of energy again, valve B is closed and valve A is opened; when the manual mechanical delay control mechanism has completed energy release, valve A is closed.

[0008] Preferably, the manual mechanical delay control mechanism includes an outer cylinder, a positioning seal, a moving part, a manual button, and a return spring. The outer cylinder and the positioning seal form a cavity with a certain volume inside. The cavity is sealed to the outside and filled with a liquid with a certain viscosity. The cavity is provided with a moving part that divides its interior into an upper cavity and a lower cavity. The moving part and the outer cylinder have a damping channel for connecting the upper cavity and the lower cavity.

[0009] Preferably, the manual button is linked to the moving component, the manual button is equipped with a one-way block, the moving component is provided with a first channel connecting the upper cavity and the lower cavity, the cross-sectional areas of the first channel and the damping channel are in a certain ratio, the one-way block is disposed in the upper cavity for one-way blocking of the first channel, and a return spring is provided below the moving component.

[0010] Preferably, the manual mechanical delay control mechanism uses a spring-loaded energy storage system and releases the energy through a delayed escapement mechanism.

[0011] Preferably, the switch control mechanism A includes a valve seat A and a moving rod for sealing or opening the valve seat A. A spring A is mounted on the moving rod, and a seal A is installed at one end of the moving rod facing the valve seat A. The other end of the moving rod is connected to a rotating shaft via a cam structure. The switch control mechanism B has the same structure as switch control mechanism A. One end of the rotating shaft is linked to a manual mechanical delay control mechanism, and the other end is connected to a cam shaft. Both ends of the cam shaft are respectively provided with cam structures for driving switch control mechanism A and switch control mechanism B to open. When one of switch control mechanism A or switch control mechanism B is opened by the cam structure, the other is closed.

Detailed Implementation Methods

[0030] Example 1

[0031] See Figure 2 The present invention discloses a toilet flushing system with delayed control switching, comprising a main water inlet 10 connected to a water source, and outlets A101 and B102 connected in parallel to the main water inlet 10. Valves A1 and B2 are respectively connected in series to outlets A101 and B102. The system also includes a manual mechanical delay control mechanism 3. Valves A1 and B2 are respectively provided with switch control mechanisms A11 and B21 connected to the manual mechanical delay control mechanism 3. By operating the manual mechanical delay control mechanism 3, the system controls the opening and closing of valves A1 and B2 and the valve opening time in a time sequence.

[0032] Example 2

[0033] Based on Embodiment 1, the manual mechanical delay control mechanism 3 controls the opening and closing of valves A1 and B2 according to the designed timing sequence. In this embodiment, when the manual mechanical delay control mechanism 3 is operated to the position where it has reached its maximum energy storage, valve A1 is opened first; after the manual mechanical delay control mechanism 3 releases a certain proportion of energy, valve A1 is closed and valve B2 is opened; when the energy release by the manual mechanical delay control mechanism 3 is complete, valve B2 is closed.

[0034] Example 3

[0035] Based on Example 1, the manual mechanical delay control mechanism 3 controls the opening and closing of valves A1 and B2 according to the designed timing sequence. Before the manual mechanical delay control mechanism 3 is operated to the maximum energy storage position, valve A1 is opened first; when the manual mechanical delay control mechanism 3 is operated to the maximum energy storage position, valve A1 is closed and valve B2 is opened; after the manual mechanical delay control mechanism 3 releases a certain proportion of energy, valve B2 is closed and valve A1 is opened; when the energy release of the manual mechanical delay control mechanism 3 is completed, valve A1 is closed.

[0036] Example 4

[0037] Based on Example 1, the manual mechanical delay control mechanism 3 controls the opening and closing of valves A1 and B2 according to the designed timing sequence. In this example, when the manual mechanical delay control mechanism 3 is operated to its maximum energy storage position, valve A1 is opened first; after the manual mechanical delay control mechanism 3 releases a certain proportion of energy, valve A1 is closed and valve B2 is opened; after the manual mechanical delay control mechanism 3 releases a certain proportion of energy again, valve B2 is closed and valve A1 is opened; when the energy release of the manual mechanical delay control mechanism 3 is complete, valve A1 is closed.

[0038] Example 5

[0039] See Figure 3 and Figure 4 In this embodiment, valve A1, valve B2, and manual mechanical delay control mechanism 3 can be combined into a combined valve, which has an outlet A101, an outlet B102, and an inlet 103. (See reference...) Figure 6 The manual mechanical delay control mechanism 3 includes an outer cylinder 31, a positioning seal 32, a moving part 33, a manual button 34, and a return spring 36. The outer cylinder 31 and the positioning seal 32 form a cavity with a certain volume inside. The cavity is sealed to the outside and filled with a liquid with a certain viscosity. The cavity is provided with a moving part 33 that divides the inside into an upper cavity 301 and a lower cavity 302. There is a damping channel between the moving part 33 and the outer cylinder 31 for connecting the upper cavity 301 and the lower cavity 302. The damping channel is a gap formed by the moving part 33 and the inner wall of the outer cylinder 31.

[0040] Furthermore, the manual button 34 is linked to the moving component 33. The manual button 34 is equipped with a one-way block 35, and the moving component 33 has a first channel connecting the upper cavity 301 and the lower cavity 302. The cross-sectional areas of the first channel and the damping channel are in a certain ratio. The one-way block 35 is disposed in the upper cavity 301 to unidirectionally block the first channel. A return spring 36 is disposed below the moving component 33. When the manual button 34 is pressed, the one-way block 35 opens, and the liquid in the upper cavity 301 and the lower cavity 302 exchanges liquid together with the first channel through the damping channel. This can effectively accelerate the pressing speed of the manual button 34. When the moving component 33 returns, the one-way block 35 seals the first channel. In this way, the liquid in the upper cavity 301 and the lower cavity 302 can only exchange liquid through the damping channel (which has a relatively small area). This liquid exchange is relatively slow, thus achieving the delayed return function of the button.

[0041] The working principle of this embodiment: The initial state before manual button 34 is pressed is as follows: Figure 6 As shown. See also Figure 9When the manual button 34 is pressed, the moving part 33 moves downward, the one-way block 35 is opened, and the connecting hole between the upper cavity 301 and the lower cavity 302 becomes larger. At this time, the connecting hole includes the first channel on the moving part 33 and the damping channel between the moving part 33 and the outer cylinder 31, and the moving part 33 can be quickly pressed down into place, such as... Figure 12 As shown, when the moving part 33 begins to return to its original position due to the return spring 36, the one-way block 35 closes the first channel. The connecting hole between the upper and lower cavities 302 is only the damping channel between the moving part 33 and the outer cylinder 31. The connecting hole is very small, so the return speed of the moving part 33 is relatively slow. In this embodiment, by controlling the size of the first channel, the gap between the moving part 33 and the outer cylinder 31, the size of the return spring 36, and the viscosity of the liquid, relatively precise control can be achieved over the pressing time and return time of the moving part 33.

[0042] Example 6

[0043] In this embodiment, the manual mechanical delay control mechanism 3 can also be controlled by a delay device such as a spring, which can store energy and release energy through an escapement mechanism with a delay.

[0044] Example 7

[0045] See Figure 3 and Figure 7 Based on embodiment 5, in this embodiment, the switch control mechanism A11 is provided with a valve seat A111 and a moving rod 112 for blocking or opening the valve seat A111. A spring A113 is provided on the moving rod 112. A sealing element A1002 is installed on one end of the moving rod 112 facing the valve seat A111. The other end of the moving rod 112 cooperates with the rotating shaft 4 through a cam structure 420. The switch control mechanism B21 has the same structure as the switch control mechanism A11. One end of the rotating shaft 4 is linked to the manual mechanical delay control mechanism 3, and the other end of the rotating shaft 4 is connected to the cam shaft 42. The two ends of the cam shaft 42 are respectively provided with cam structures 420 for driving the switch control mechanism A11 and the switch control mechanism B21 to open. When the cam structure 420 drives one of the switch control mechanism A11 or the switch control mechanism B21 to open, the other closes.

[0046] The working principle of this embodiment is as follows: (See attached document) Figure 7 , Figure 8 , Figure 10 and Figure 11When the rotating shaft 4 rotates, it drives the cam structures 420 at both ends to rotate via the cam shaft 42. The cam structures 420 convert the rotation of the cam shaft 42 into horizontal movement. One of the cam structures 420 abuts against the moving rod 112, which moves the seal A1002 on the switch control mechanism A11 away from the valve seat A111, thus opening the valve A1. The other cam structure 420 disengages from abutting against the moving rod 112. At this time, the seal A1002 on the switch control mechanism B21 is pressed against the valve seat A111 by the spring A113, thus closing the valve B2. Figure 11 As shown. In the switch control mechanism A11, the upper chamber of the diaphragm of valve A1 is connected to the valve seat A111. When the valve seat A111 is opened, the water in the upper chamber of the diaphragm of valve A1 can flow out from the valve seat A111, and valve A1 is opened. The water flowing out from the valve seat A111 flows directly to the outside from the back. The opening process of the switch control mechanism B21 is the same.

[0047] The working process of this embodiment: The manual button 34 is... Figures 6 to 8 Pressing the initial state shown Figures 9 to 11 In the middle position shown, one of the cam structures 420 moves the seal A1002 on the switch control mechanism A11 away from the valve seat A111, opening valve A1; the other cam structure 420 disengages from the abutment of the moving rod 112. At this time, the seal A1002 on the switch control mechanism B21 is pressed against the valve seat A111 by the spring A113, closing valve B2. When the manual button 34 is pressed further down from the middle position... Figures 12 to 14 When the switch control mechanism A11 is in the bottom state, the cam structure 420 in the switch control mechanism A11 disengages from the moving rod 112, the moving rod 112 is reset under the action of the spring A113, and the seal A re-seals the valve seat A111, thus closing the valve A1; the cam structure 420 in the switch control mechanism B21 rotates to a state that allows the seal A1002 to move away from the valve seat A111, thus opening the valve B2.

[0048] Example 8

[0049] See Figure 7 Based on Embodiment 7, in this embodiment, the manual mechanical delay control mechanism 3 is linked to the rotating shaft 4 via a connecting rod 41. One end of the connecting rod 41 is connected to the manual mechanical delay control mechanism 3, and the other end of the connecting rod 41 is rotatably connected to the rotating shaft 4. Specifically, in this embodiment, the connecting rod 41 is connected to the rotating shaft 4 using a structure of a locking pin and a sliding groove. The end of the connecting rod 41 has a connector with a sliding groove, and the end of the rotating shaft 4 has a locking pin movably installed within the sliding groove.

[0050] Example 9

[0051] The difference between this embodiment and embodiment 8 is that the connecting rod 41 is connected to the rotating shaft 4 by a gear meshing structure.
