[0042] The application will be further described below in conjunction with the accompanying drawings. Figure 1 - The accompanying drawings illustrate the embodiments of the application. Figure 5 The application will be further described below in conjunction with the accompanying drawings.

[0043] The application discloses a toilet flushing device.

[0044] The application discloses a toilet flushing device, which is applied to squatting toilets, sitting toilets, urinals and other toilet products. The toilet flushing device is used for flushing the dirt in the toilet.

[0045] Reference Figure 1 As shown in the drawings, the flushing system comprises 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 sensing element 7. The flushing tank 1 is a main storage tool for flushing water and can be installed on the wall surface, the ground or a fixed placement space in the use environment. The flushing tank 1 is internally provided with a partition 8. The main function of the partition 8 is to divide the space in the flushing tank 1. For example, the partition 8 divides the internal space of the flushing tank 1 into a first water storage cavity 11 and a second water storage cavity 12. The water storage space of the first water storage cavity 11 is larger than that of the second water storage cavity 12, so that the flushing water in the first water storage cavity 11 can be used to flush the feces or the dirt requiring a large amount of water. The second water storage cavity 12 is smaller than the first water storage cavity 11, so that it can be used to flush the urine or the dirt requiring a small amount of water. Therefore, the first water storage cavity 11 and the second water storage cavity 12 can provide a corresponding water environment to achieve the effect of reasonably allocating the flushing water and saving water resources.

[0046] The drain 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 in communication with the first water storage cavity 11, and the second branch pipe 32 is in communication with the second water storage cavity 12. The first branch pipe 31 and the second branch pipe 32 converge into the main pipe 33, and the first branch pipe 31 and the second branch pipe 32 are both provided with the drain valve 2. The first branch pipe 31 and the second branch pipe 32 respectively discharge the flushing water in the first water storage cavity 11 and the second water storage cavity 12 into the main pipe 33. The main pipe 33 is in communication with the external toilet, the squatting toilet, the urinal and other toilets. When any drain valve 2 discharges the flushing water, the flushing water will flow into the main pipe 33 and then be used to flush the dirt in the toilet through the main pipe 33.

[0047] The first water storage cavity 11 is provided with a water inlet pipe 4, and the water inlet pipe 4 is provided with a water inlet valve 5. The water inlet pipe 4 is used to supplement the flushing water in the flushing tank 1 and is connected to a water supply pipe. The first water storage cavity 11 is provided with a sensing element 7. The sensing element 7 can be a liquid level sensor. The liquid level sensor can sense the amount of flushing water in the first water storage cavity 11 and determine whether the flushing water needs to be supplemented.

[0048] The partition 8 is provided with a one-way valve 13. The flow direction of the one-way valve 13 is from the first water storage cavity 11 to the second water storage cavity 12. The one-way valve 13 allows the water in the first water storage cavity 11 to flow into the second water storage cavity 12, but the water in the second water storage cavity 12 cannot flow into the first water storage cavity 11. After the flushing water in the second water storage cavity 12 is discharged, the flushing water in the first water storage cavity 11 can supplement the second water storage cavity 12 through the one-way valve 13. After the flushing water in the first water storage cavity 11 is discharged, the water in the second water storage cavity 12 cannot flow into the first water storage cavity 11, but the water inlet valve 5 can be opened by the sensing element 7 to supplement the water. The sensing element 7 does not need to be provided in the second water storage cavity 12, which reduces the number of sensing elements 7 that need to be installed and reduces the cost of consumables.

[0049] The control cover plate 6 is detachably connected to the tank opening of the flushing tank 1 and is electrically connected to the sensing element 7, the drain valve 2, and the water inlet valve 5. The control cover plate 6 is provided with a controller and a control button on the surface. The control button can be a physical button or a touch button. The control cover plate 6 is used to cover the flushing tank 1 to prevent the water in the flushing tank 1 from spilling out and to control the sensing element 7, the drain valve 2, and the water inlet valve 5. When the sensing element 7 senses that the flushing water needs to be supplemented, an electrical signal is sent to the control cover plate 6. The control cover plate 6 sends a water supplement instruction to the water inlet valve 5, and the water inlet valve 5 opens to supplement the water. The drain valve 2 is provided with a urination flushing button and a defecation flushing button. When the corresponding button is pressed, the control cover plate 6 sends a flushing instruction to the corresponding drain valve 2 to open the corresponding water storage cavity for drainage and flushing.

[0050] Specifically, the partition 8 divides the internal space of the flushing tank 1 into the first water storage cavity 11 and the second water storage cavity 12, so that the first water storage cavity 11 and the second water storage cavity 12 correspond to different flushing environments. The control cover plate 6 provides control of water drainage and water inlet, so that the flushing water in the flushing tank 1 can be accurately discharged and supplemented. The one-way valve 13 provides one-way water flow, which reduces the installation cost of the sensing element 7. Through the cooperation of various structures, the flushing water can be reasonably distributed, the waste of water resources can be reduced, and the effect of water saving can be achieved.

[0051] In some embodiments, reference is made to Figure 2As shown, the partition 8 comprises a fixed frame 81, a sliding frame 82 and an elastic connecting piece 83; the fixed frame 81 is installed on the inner side wall of the flushing tank 1, the sliding frame 82 is smaller in size than the fixed frame 81, the sliding frame 82 is inserted into the fixed frame 81, and the sliding frame 82 is in communication with the fixed frame 81, both the fixed frame 81 and the sliding frame 82 adopt a half-frame structure, i.e., the opposite faces 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 both the fixed frame 81 and the sliding frame 82 are closed at the bottom to provide a water receiving space for flushing.

[0052] The elastic connecting piece 83 is connected between the sliding frame 82 and the fixed frame 81, and can be made of plastic or rubber, and has elasticity and toughness; when the sliding frame 82 is inserted into the fixed frame 81, the elastic connecting piece 83 is bent, so that the water inside will not leak out, and the stability of water storage is ensured.

[0053] Specifically, the insertion depth of the fixed frame 81 and the sliding frame 82 can adjust the water storage space of the second water storage cavity 12, so as to adapt to different requirements of flushing water, such as in areas where water resources are scarce, the space of the second water storage cavity 12 can be reduced, so that the amount of single flushing is less, and the elastic connecting piece 83 provides sealing for the gap and the connection between the sliding frame 82 and the fixed frame 81, to prevent water in the second water storage cavity 12 from flowing out.

[0054] The drain valve 2 can be arranged at the fixed frame 81, and the one-way valve 13 can be arranged at the fixed frame 81 or the sliding frame 82, and the installation position is determined according to requirements.

[0055] Further, referring to Figure 3 As shown, the bottom of the partition 8 is provided with a support 9, which is installed on the side wall of the flushing tank 1, and the support is used to provide support for the partition 8, especially for the sliding frame 82; the fixed frame 81 is directly connected with the inner wall of the flushing tank 1, so it has a stable fixed connection, while the sliding frame 82 has no specific connection point, and it is easy to deviate and bend when it is unfolded too long, so the support 9 is arranged at the bottom of the partition 8 to provide support for the fixed frame 81 and the sliding frame 82.

[0056] The bottom of the support 9 can be provided with a reinforcing rib 93, which can improve the supporting capacity of the support 9, avoid bending and other conditions caused by excessive stress, and prolong the service life of the overall support 9 and the partition 8.

[0057] Further, referring to Figure 3As shown, the support 9 comprises a sliding rail 91 and a sliding part 92; the sliding rail 91 is installed at the bottom of the support 9, the sliding part 92 is connected with the outer bottom end of the sliding frame 82, and the sliding part 92 is in sliding connection with the sliding rail 91; the sliding part 92 can be a sliding block, and the sliding rail 91 is provided with two groups, which can be I-shaped sliding rails, and the openings are oppositely installed, respectively located on both sides of the fixed frame 81, and extend out of the fixed frame 81 to the direction of the sliding frame 82.

[0058] 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 be supported by the sliding rail 91 through the sliding part 92, and the sliding frame 82 can be stably supported whether it is inserted into the fixed frame 81 or separated from the fixed frame 81, and the elastic connecting piece 83 is expanded to a larger water storage space, which can increase the space of the second water storage cavity 12 through the elastic connecting piece 83.

[0059] In some embodiments, referring to Figure 3 As shown, the support 9 is also provided with a pivoting part, a lead screw 94 and a handle 95; the pivoting part can be a pivoting bearing or a pivoting hole, and the pivoting part is specifically installed at the bottom of the support 9; the lead screw 94 is in pivoting connection with the pivoting part, that is, the lead screw 94 can rotate along the pivoting part, and the pivoting part is blocked in the illustration, so it is not shown.

[0060] The sliding part 92 is provided with a threaded hole, the lead screw 94 penetrates the threaded hole and is screwed with the threaded hole, and extends to the end away from the pivoting part after penetrating the threaded hole; the handle 95 is installed at the end of the lead screw 94 away from the pivoting part; the sliding part 92 is limited by the sliding rail 91 and cannot rotate with the lead screw 94; the user can rotate the lead screw 94 by using the handle 95; during the rotation of the lead screw 94 along the pivoting part, the sliding part 92 slides along the sliding rail 91, so that the sliding part 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 expand the elastic connecting piece 83; at the same time, the sliding frame 82 can also be stabilized, and the screwing action of the lead screw 94 makes the sliding frame 82 unable to move at will, and only the lead screw 94 can adjust the position of the sliding frame 82, thereby avoiding the situation that the sliding frame 82 is affected by water pressure and swings at will during water replenishment or drainage of the second water storage cavity 12.

[0061] In some embodiments, referring to Figure 4 and Figure 5 As shown, the sliding frame 82 is provided with an abutting part 821, which is bent outwardly so that the bent surface abuts against the outer wall of the fixed frame 81; the abutting part 821 can be a bent abutting bracket, and the abutting bracket can support part of the elastic connecting piece 83.

[0062] When the sliding frame 82 is separated from the fixed frame 81 along the sliding rail 91, the sliding frame 82 can be continuously moved away from the fixed frame 81, so that the elastic connecting piece 83 is unfolded to expand the space of the second water storage cavity 12. Although the elastic connecting piece 83 is affected by the water pressure in the second water storage cavity 12, it is still affected by the water pressure inside the second water storage cavity 12 or outside the first water storage cavity 11. Therefore, the sliding frame 82 is connected with an abutting portion 821, which moves synchronously with the fixed frame 81. When the second water storage cavity 12 is replenished with water for flushing, the elastic connecting piece 83 is affected by the water pressure and expands outward, and the abutting portion 821 abuts against the expansion path, thereby protecting the elastic connecting piece 83.

[0063] Further, as shown in Figure 5 The abutting portion 821 is provided with an abutting protrusion 8211, and when the sliding frame 82 moves away from the fixed frame 81, the elastic connecting piece 83 is unfolded, the abutting portion 821 moves synchronously along the outer wall of the fixed frame 81, the elastic connecting piece 83 is completely unfolded, the abutting protrusion 8211 abuts against the outer wall of the elastic connecting piece 83, and the abutting protrusion 8211 can be more closely attached to the elastic connecting piece 83, so that the supporting effect of the elastic connecting piece 83 is better.

[0064] Further, as shown in Figure 4 Or Figure 5 The outer wall of the fixed frame 81 is provided with a limiting groove 811, the abutting portion 821 is in sliding connection with the limiting groove 811, and the limiting groove 811 limits the abutting portion 821. The movement track of the abutting portion 821 is fixed by the limiting groove 811, 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. Meanwhile, one end of the abutting portion 821 is supported by the sliding frame 82, and the other end is supported by the fixed frame 81, thereby ensuring the stable abutting of the elastic connecting piece 83.

[0065] Further, the sliding portion 92 is provided with a sliding protrusion, which abuts against the outer bottom surface of the elastic connecting piece 83. The abutting portion 821 abuts against and supports the side wall of the elastic connecting piece 83, and the sliding protrusion on the sliding portion 92 is used to abut against and support the bottom of the elastic connecting piece 83, thereby further improving the stability of the elastic connecting piece 83 when receiving water for flushing. In the drawings, the sliding portion 92 is blocked, so the sliding protrusion is not shown.

[0066] The embodiments of the specific implementation are the preferred embodiments of the present application, and are not intended to limit the protection scope of the present application. The same parts are indicated by the same reference numerals. Therefore, any equivalent changes made according to the structure, shape and principle of the present application should be covered by the protection scope of the present application.
