In addition, when a device is said to "include" a certain component, unless otherwise stated, it does not exclude other components, but means that other components may be included.

[0032] The following is combined with Figure 1 -Attached Figure 5 , further details of this application are given.

[0033] The embodiment of the present application discloses a toilet flushing device.

[0034] A toilet flushing device is used in toilet products such as squat toilets, sitting toilets, urinals, etc. The present invention is used to flush out the dirt in the toilet.

[0035] refer to Figure 1 As shown, the flushing system includes a flushing tank 1, a drain valve 2, a drain pipe 3, a water inlet pipe 4, a water inlet valve 5, a control cover plate 6 and a sensor 7; the flushing tank 1 is a main storage device for flushing water, which can be installed on a wall, a ground or a fixed placement space in the use environment. A partition 8 is provided inside the flushing tank 1. The main function of the partition 8 is to divide the space inside the flushing tank 1. For example, the partition 8 divides the internal space of the flushing tank 1 into a first water storage chamber 11 and a second water storage chamber 12. The water storage space of the first water storage chamber 11 is larger than the water storage space of the second water storage chamber 12, so that the flushing water in the first water storage chamber 11 can be used to flush feces or dirt requiring a large amount of water. The second water storage chamber 12 is smaller than the first water storage chamber 11, so it can be used to flush urine or dirt requiring a small amount of water. Therefore, the first water storage chamber 11 and the second water storage chamber 12 can provide a water environment corresponding to the demand, so as to achieve the effect of reasonably allocating flushing water, reducing the waste of water resources, and saving water.

[0036] The drainage pipe 3 is divided into a first branch pipe 31, a second branch pipe 32 and a main pipe 33. The first branch pipe 31 is connected to the first water storage chamber 11, and the second branch pipe 32 is connected to the second water storage chamber 12. The first branch pipe 31 and the second branch pipe 32 intersect to the main pipe 33, and the first branch pipe 31 and the second branch pipe 32 are both provided with a drainage valve 2. The first branch pipe 31 and the second branch pipe 32 discharge the flushing water in the first water storage chamber 11 and the second water storage chamber 12 respectively, and discharge them into the main pipe 33. The main pipe 33 is connected to external toilets such as toilets, squat toilets, and urinals. Any drainage valve 2 will discharge the flushing water, which will flow into the main pipe 33, and the dirt in the toilet will be drained and flushed through the main pipe 33.

[0037] A water inlet pipe 4 is provided in the first water storage chamber 11, and a water inlet valve 5 is provided at the water inlet pipe 4. The water inlet pipe 4 is used to replenish the flushing water in the flushing tank 1 and is externally connected to the water supply pipeline. The first water storage chamber 11 is provided with a sensing element 7. The sensing element 7 can adopt a liquid level sensor. The liquid level sensor can be used to sense the amount of flushing water in the first water storage chamber 11 to determine whether it needs to be replenished.

[0038] A one-way valve 13 is provided on the partition 8, and the flow direction of the one-way valve 13 is that the first water storage chamber 11 flows into the second water storage chamber 12. The function of the one-way valve 13 is to enable the water in the first water storage chamber 11 to flow into the second water storage chamber 12, while the water in the second water storage chamber 12 cannot flow into the first water storage chamber 11, so that after the flushing water in the second water storage chamber 12 is discharged, the flushing water in the first water storage chamber 11 can be used to replenish the second water storage chamber 12 through the one-way valve 13, and after the flushing water in the first water storage chamber 11 is discharged, the water in the second water storage chamber 12 cannot flow into the first water storage chamber 11, but can be replenished by opening the water inlet valve 5 through the sensor 7, and there is no need to set the sensor 7 in the second water storage chamber 12, thereby reducing the required installed sensor 7 and reducing the cost of consumables.

[0039] The control cover 6 is detachably connected to the box opening of the flush tank 1 and is electrically connected to the sensor 7, the drain valve 2, and the water inlet valve 5. The control cover 6 has a built-in controller and control buttons on the surface, which can be physical buttons or touch buttons. The control cover 6 is used to cover the flush tank 1 to prevent water in the flush tank 1 from splashing out, and is also used to provide control of the sensor 7, the drain valve 2 and the water inlet valve 5. When the sensor 7 senses that flushing water needs to be replenished, it sends an electrical signal to the control cover 6, and the control cover 6 sends a water replenishment instruction to the water inlet valve 5, and the water inlet valve 5 is opened to replenish water. The drain valve 2 is uniformly provided with a urine flushing button and a stool flushing button. Press the corresponding button, and the control cover 6 sends a flushing instruction to the corresponding drain valve 2, and opens the corresponding water storage cavity for drainage and flushing.

[0040] Specifically, the internal space of the flush tank 1 is divided into a first water storage chamber 11 and a second water storage chamber 12 by a partition 8, so that the first water storage chamber 11 and the second water storage chamber 12 correspond to different flushing environments respectively, and the control cover 6 is used to provide drainage and water inlet control, so that the flushing water in the flush tank 1 can be accurately discharged and replenished, and the one-way valve 13 is used to provide one-way water flow, thereby reducing the installation cost of the required sensor 7. Through the coordination of various structures, the flushing water is reasonably distributed, the waste of water resources is reduced, and the effect of saving water is achieved.

[0041] In some embodiments, reference Figure 2 As shown, the partition 8 includes a fixed frame 81, a sliding frame 82 and an elastic connecting piece 83; the fixed frame 81 is installed on the inner wall of the flush tank 1, the size of the sliding frame 82 is smaller than that of the fixed frame 81, the sliding frame 82 is plugged into the fixed frame 81, and the sliding frame 82 is connected to the fixed frame 81, and the fixed frame 81 and the sliding frame 82 both adopt a semi-frame structure, that is, the opposite surfaces of the fixed frame 81 and the sliding frame 82 are both open, so that the sliding frame 82 can be inserted into the fixed frame 81, and at the same time, the fixed frame 81 and the sliding frame 82 are both bottom-sealed to provide a receiving space for flushing water.

[0042] An elastic connecting piece 83 is connected between the sliding frame 82 and the fixed frame 81. The elastic connecting piece 83 can be made of a plastic sheet or a rubber sheet, which has elasticity and toughness. When the sliding frame 82 and the fixed frame 81 are plugged in, the elastic connecting piece 83 bends so that the water inside will not leak out, thereby ensuring the stability of water storage.

[0043] Specifically, the insertion depth of the fixed frame 81 and the sliding frame 82 can adjust the size of the water storage space of the second water storage chamber 12, so as to adapt to the flushing volume of different requirements. For example, in areas where water resources are relatively scarce, the space of the second water storage chamber 12 can be reduced to make the single flushing volume smaller. The elastic connecting piece 83 is used to provide a gap between the sliding frame 82 and the fixed frame 81 and the connection to prevent the water in the second water storage chamber 12 from flowing out.

[0044] The drain valve 2 may be disposed at the fixed frame 81 , and the one-way valve 13 may be disposed at the fixed frame 81 or the sliding frame 82 , and the installation position is determined according to requirements.

[0045] For further reference, Figure 3 As shown, a support member 9 is provided at the bottom of the partition 8, and the support member 9 is installed on the side wall of the flush tank 1. The support portion is used to provide support for the partition 8, especially for the sliding frame 82. The fixed frame 81 is directly connected to the inner wall of the flush tank 1, so it has the stability of a fixed connection, and the sliding frame 82 has no specific connection point. When it is unfolded too long, it is easy to deviate and bend. Therefore, the support member 9 is arranged at the bottom of the partition 8 to provide support for the fixed frame 81 and the sliding frame 82.

[0046] Among them, reinforcing ribs 93 can be set at the bottom of the support member 9. The reinforcing ribs 93 can be used to improve the supporting capacity of the support member 9, avoid bending due to excessive force, and extend the service life of the entire support member 9 and the partition 8.

[0047] Further, refer to Figure 3 As shown, the support member 9 includes a sliding rail 91 and a sliding portion 92; the sliding rail 91 is installed at the bottom of the support member 9, the sliding portion 92 is connected to the outer bottom end of the sliding frame 82, and the sliding portion 92 is slidably connected to the sliding rail 91, the sliding portion 92 can adopt a sliding block, and the sliding rail 91 is provided with two groups, which can be I-type sliding rails, and the openings are installed relative to each other, respectively located on both sides of the fixed frame 81, and extend from the fixed frame 81 to extend in the direction of the sliding frame 82.

[0048] The sliding frame 82 is installed on the sliding part 92, and the sliding part 92 can slide along the sliding rail 91, so that the sliding frame 82 can use the sliding part 92 to obtain the support of the sliding rail 91, so that no matter the sliding frame 82 is inserted into the fixed frame 81 or detached from the fixed frame 81, the elastic connecting piece 83 can be unfolded to expand a larger water storage space, and a stable support effect can be obtained, thereby achieving the effect of increasing the space of the second water storage chamber 12 through the elastic connecting piece 83.

[0049] In some embodiments, reference Figure 3 As shown, the support member 9 is also provided with a pivot portion, a screw rod 94 and a turning handle 95; the pivot portion can adopt a pivot bearing or a pivot hole, the pivot portion is specifically installed at the bottom of the support member 9, and the screw rod 94 is pivotally connected to the pivot portion, that is, the screw rod 94 can rotate along the pivot portion. The pivot portion is blocked in the figure and is therefore not shown.

[0050] The sliding portion 92 is provided with a threaded hole, and the screw rod 94 passes through the threaded hole and is screwed to the threaded hole, and then extends to the end away from the pivot portion after passing through the threaded hole. The turning handle 95 is installed on the end of the screw rod 94 away from the pivot portion. The sliding portion 92 is limited by the sliding rail 91 and cannot rotate with the screw rod 94. The user can use the turning handle 95 to rotate the screw rod 94. During the rotation of the screw rod 94 along the pivot portion, the sliding portion 92 slides along the sliding rail 91, so that the sliding portion 92 can drive the sliding frame 82 to move, thereby adjusting the position of the sliding frame 82 to determine whether the sliding frame 82 is inserted into the fixed frame 81 or pulled out of the fixed frame 81, and the elastic connecting piece 83 is unfolded. At the same time, the sliding frame 82 can also be stabilized. The screw connection effect of the screw rod 94 is utilized to make the sliding frame 82 unable to move at will. The position of the sliding frame 82 can only be adjusted by turning to the screw rod 94, so as to avoid the sliding frame 82 swinging at will due to the influence of water pressure when the second water storage chamber 12 is replenished or drained.

[0051] In some embodiments, reference Figure 4 and Figure 5 As shown, the sliding frame 82 is provided with an abutment portion 821, which is bent outward so that the bent surface abuts against the outer wall of the fixed frame 81. The abutment portion 821 can adopt a bent abutment frame, and the function of the abutment frame is to partially support the elastic connecting piece 83.

[0052] After the sliding frame 82 is separated from the fixed frame 81 along the sliding rail 91, the sliding frame 82 can continue to be moved away from the fixed frame 81, so that the elastic connecting piece 83 is unfolded, thereby expanding the space of the second water storage chamber 12. Although in the underwater environment of the first water storage chamber 11, the elastic connecting piece 83 is reduced by the water pressure of the second water storage chamber 12, it will still be affected by the water pressure inside the second water storage chamber 12 or outside the first water storage chamber 11. Therefore, the sliding frame 82 is connected to a butt portion 821, and the butt portion 821 moves synchronously with the fixed frame 81. When the second water storage chamber 12 is replenished with flushing water, the elastic connecting piece 83 is affected by the water pressure and expands outward, and the butt portion 821 is used to resist the expansion path, thereby providing protection for the elastic connecting piece 83.

[0053] For further reference, Figure 5As shown, an abutting protrusion 8211 is provided on the abutting portion 821. When the sliding frame 82 moves away from the fixed frame 81, the elastic connecting piece 83 is unfolded, and the abutting portion 821 moves along the outer wall of the fixed frame 81 synchronously. The elastic connecting piece 83 is fully unfolded, and the abutting protrusion 8211 abuts against the outer wall of the elastic connecting piece 83. The abutting protrusion 8211 can be closer to the elastic connecting piece 83, so that the supporting effect of the elastic connecting piece 83 is better.

[0054] Further, refer to Figure 4 or Figure 5 As shown, a limiting groove 811 is provided on the outer wall of the fixed frame 81, and the abutting portion 821 is slidably connected to the limiting groove 811 and provides a limit for the abutting portion 821. The limiting groove 811 can be used to fix the moving trajectory of the abutting portion 821, so that the abutting portion 821 can only move along the limiting groove 811 and cannot be separated from the limiting groove 811, thereby ensuring the stable movement of the abutting portion 821. At the same time, the other end is fixed by the limiting groove 811. When it is pressed tightly due to the expansion of the elastic connecting piece 83, one end provides support through the sliding frame 82 and the other end provides support through the fixed frame 81, thereby ensuring the stable pressing of the elastic connecting piece 83.

[0055] Furthermore, a sliding protrusion is provided on the sliding portion 92, and the sliding protrusion abuts against the outer bottom surface of the elastic connecting piece 83. The abutting portion 821 provides abutting support for the side wall of the elastic connecting piece 83. The sliding protrusion on the sliding portion 92 is used to abut and support the bottom of the elastic connecting piece 83, thereby further improving the stability of the elastic connecting piece 83 when receiving flushing water. The sliding portion 92 is blocked in the figure, so the sliding protrusion is not shown.

[0056] The embodiments of this specific implementation are all preferred embodiments of the present application, and are not intended to limit the protection scope of the present application. The same components are represented by the same figure marks. Therefore, any equivalent changes made based on the structure, shape, and principle of the present application should be included in the protection scope of the present application.
