Description

Technical Field

[0001] This invention relates to the technical field of sanitary ware, and more particularly to a flushing system and a toilet seat thereof. Background Technology

[0002] Toilets are convenient and hygienic, allowing for easy waste removal via flushing. Current toilet flushing systems are directly connected to tap water, and consist of a control device and flushing pipes. The control device manages the flushing pipes to achieve flushing and waste removal. However, existing toilets typically require multiple flushing pipes, and current control devices struggle to efficiently manage multiple pipes simultaneously. This often leads to insufficient water volume and reduced flushing efficiency, requiring multiple flushes to achieve thorough waste removal, resulting in poor flushing performance. Therefore, existing toilet flushing systems suffer from low flushing efficiency. Summary of the Invention

[0074] In this embodiment, please refer to Figures 1 to 14 As shown in the figure, this embodiment of the invention provides a flushing system 60, which is used to control the flushing of the washing pipe 121 and the jet pipe 122 in the toilet 1. The flushing system 60 includes an induction reversing valve 61, an induction inlet valve 62, and a control device 63.

[0075] In a more specific embodiment, the control device 63 includes an inlet induction valve 64, a dual-path induction valve 65, and a mechanical switch 66; the inlet induction valve 64 includes an induction valve body 641, an induction valve inlet 642 and an induction valve control port 643 disposed on the induction valve body 641, and an inlet induction valve core 644 disposed within the induction valve body 641; the induction valve control port 643 is connected to the inlet valve induction port 624; the mechanical switch 66 controls the movement of the inlet induction valve core 644 to control the connection or disconnection between the induction valve inlet 642 and the induction valve control port 643; the dual-path induction valve 65 includes a dual-path induction valve body 651, a first induction connector 652, a second induction connector 653, a first control port 654, and a second control port 655 disposed on the dual-path induction valve body 651, and a reversing induction valve core 656 disposed within the dual-path induction valve body 651; the first control port 654 is connected to the first outlet control port 624. 15 are connected, and the second control port 655 is connected to the second outlet control port 616; the mechanical switch 66 controls the movement of the reversing induction valve core 644 to control the first induction connector 652 to connect with the first control port 654 and control the second induction connector 653 to disconnect from the second control port 655, or controls the first induction connector 652 to disconnect from the first control port 654 and controls the second induction connector 653 to connect with the second control port 655; the mechanical switch 66 includes a switch rod 661, a first lever 662 and a second lever 663 fixedly disposed on the switch rod 661, the first lever 662 is embedded in the recess of the inlet induction valve core 644 so as to drive the inlet induction valve core 644 to move through the first lever 662; the second lever 663 is embedded in the recess of the reversing induction valve core 656 so as to drive the reversing induction valve core 656 to move through the second lever 663.

[0076] Specifically, the mechanical switch 66 simultaneously disconnects the passage between the first induction connector 652 and the first control port 654, and the passage between the second induction connector 653 and the second control port 655. When the reversing induction valve core 644 moves to one end, disconnecting the passage between the second induction connector 653 and the second control port 655, the passage between the first induction connector 652 and the first control port 654 is connected. When the reversing induction valve core 644 moves to the other end, disconnecting the passage between the first induction connector 652 and the first control port 654, the passage between the second induction connector 653 and the second control port 655 is connected. Furthermore, when the reversing induction valve core 644 moves to the intermediate position, it can simultaneously connect the passage between the first induction connector 652 and the first control port 654, and the passage between the second induction connector 653 and the second control port 655.

[0077] In a more specific embodiment, the control device 63 includes a dual-path induction valve 65 and a mechanical switch 66; the dual-path induction valve 65 includes a dual-path induction valve body 651, a first induction connector 652, a second induction connector 653, a first control port 654, a second control port 655 disposed on the dual-path induction valve body 651, and a reversing induction valve core 656 disposed within the dual-path induction valve body 651; the first control port 654 is connected to the first outlet control port 615, and the second control port 655 is connected to the second outlet control port 616; the mechanical switch 66 controls the reversing induction valve core 644. The movement controls the first induction connector 652 to connect with the first control port 654 and controls the second induction connector 653 to disconnect from the second control port 655, or controls the first induction connector 652 to disconnect from the first control port 654 and controls the second induction connector 653 to connect with the second control port 655; the mechanical switch 66 includes a switch rod 661 and a lever (same as the second lever 633 in the above embodiment) fixedly disposed on the switch rod 661. The lever is embedded in the recess of the reversing induction valve core 656 so as to drive the reversing induction valve core 656 to move through the lever.

[0078] In a more specific embodiment, the mechanical switch 66 further includes a switch cover 664 disposed outside the switch rod 661; the switch cover 664 is fixedly disposed on the dual-path induction valve 65 and the water inlet induction valve 66, a switch spring 665 is provided between the switch rod 661 and the switch cover 664, and a spring fixing rod 666 is also provided on the switch rod 661, and the switch spring sleeve 665 is disposed on the spring fixing rod 666; the switch rod 661 is driven by manual pressing and the elastic force of the switch spring 665 to perform reciprocating motion.

[0079] In the event of a power outage, the user can press the switch lever 661 to open the induction-type water inlet valve 62. At this time, the switch spring 665 is compressed, and the first half of the switch lever 661's advancement connects the induction-type reversing valve 61 with the washing pipe 121. Water is then discharged through the washing pipe 121 to clean the ceramic body 13. Afterward, pressing the switch lever 661 further advances and compresses it, switching the flow path of the induction-type reversing valve 61 in the middle section. The second half of the switch lever 661's advancement opens the spray pipe 122 to spray water, creating a siphon effect within the ceramic body 13 and completing the cleaning process. The ceramic body 13 undergoes siphon flushing; after flushing is complete, the user releases the switch lever 661. At this time, the switch spring 665 provides elastic force to drive the switch lever 661 to gradually return to the initial position. In the first half of the return of the switch lever 661, the control-induced reversing valve 61 opens the spray pipe 122. When the switch lever 661 returns to the middle section, the control-induced reversing valve 61 switches the flow path. In the second half of the return of the switch lever 661, the control-induced reversing valve 61 connects with the washing pipe 121, opening the washing pipe 121 to continue flushing and replenishing the water surface inside the ceramic body 13. When the switch lever 661 returns to the initial position, the induced water inlet valve 62 closes.

[0080] Specifically, the switch lever 661 is driven by a solenoid valve or a motor to perform reciprocating control motion; alternatively, both the water inlet induction valve core 644 and the reversing induction valve core 656 are directly driven by a solenoid valve or a motor to perform reciprocating control motion. In the power-on state, the switch lever 661 can be driven by a solenoid valve or a motor to perform reciprocating motion, and the specific method of flushing control is the same as the manual control method described above, which will not be repeated here. In the power-on state, the water inlet induction valve core 644 and the reversing induction valve core 656 can also be directly driven by a solenoid valve or a motor to perform reciprocating motion.

[0081] In a more specific embodiment, the induced reversing valve 61 further includes a first control cavity 67 and a second control cavity 68 disposed within the induced reversing valve body 611; the first control cavity 67 is connected to the first water outlet control port 615, and a first sealing water pad 671 is disposed within the first control cavity 67; when the first water outlet control port 615 is closed, the first sealing water pad 671, under water pressure, blocks the passage between the first water outlet 613 and the reversing valve inlet 612; when the first water outlet control port 615 is connected, the first sealing water pad 671, under the action of unequal pressure difference, blocks the passage between the first water outlet 613 and the reversing valve inlet 612. The passage between the outlet 613 and the inlet 612 of the reversing valve is opened; the second control cavity 68 is connected to the second outlet control port 616, and the second sealing water pad 681 is disposed in the second control cavity 68; when the second outlet control port 616 is closed, the second sealing water pad 681 blocks the passage between the second outlet 614 and the inlet 612 of the reversing valve under water pressure; when the second outlet control port 616 is opened, the second sealing water pad 681 is subjected to an unequal pressure difference to open the passage between the second outlet 614 and the inlet 612 of the reversing valve.

[0082] Specifically, when the first water outlet control port 615 is closed, the pressure inside the first control chamber 67 increases, and the water pressure pushes the first sealing water pad 671 to close the passage, thereby blocking the passage between the first water outlet 613 and the reversing valve inlet 612. When the first water outlet control port 615 remains open, a pressure difference is generated on both sides of the first sealing water pad 671, and the water pressure pushes the first sealing water pad 671 out of the closed position, thereby opening the passage between the first water outlet 613 and the reversing valve inlet 612. The second sealing water pad 681 controls the corresponding passage under the action of the second water outlet control port 616 in the same way as the first sealing water pad 671 described above.

[0083] In a more specific embodiment, the dual-path induction valve 65 further includes end seals 657 respectively disposed at both ends of the reversing induction valve core 656 and valve core seals 658 disposed at the connection between the reversing induction valve core 656 and the dual-path induction valve body 651. An induction return spring 659 is also provided between the reversing induction valve core 656 and the dual-path induction valve body 651. The end seals 657 at both ends of the reversing induction valve core 656 respectively seal the passage between the first induction connector 652 and the first control port 654 and the passage between the second induction connector 653 and the second control port 655.

[0084] The end seal 657 can be used to improve the sealing performance of the reversing induction valve core 656 in closing the passage, and the valve core seal 658 is used to tightly seal the gap between the reversing induction valve core 656 and the dual-path induction valve body 651. The induction return spring 659 can generate elastic force to push the reversing induction valve core 656 to close the passage between the first induction connector 653 and the first control port 655 without external force, that is, to connect the flushing pipeline 121 in the initial state.

[0085] In a more specific embodiment, the induced inlet valve 62 further includes an inlet valve induction chamber 625 disposed within the inlet valve body 651; the inlet valve induction chamber 625 is connected to the inlet valve induction port 624, and an inlet valve plate 626 is disposed within the inlet valve induction chamber 625; when the inlet valve induction port 624 is closed, the inlet valve plate 626 blocks the passage between the inlet valve inlet 622 and the inlet valve outlet 623 under water pressure; when the inlet valve induction port 624 is connected, the inlet valve plate 626 is subjected to an unequal pressure difference to open the passage between the inlet valve inlet 622 and the inlet valve outlet 623.

[0086] The specific way in which the inlet valve disc 626 controls the corresponding passage under the action of the inlet valve induction port 624 is the same as the working method of the first sealing water pad 671 mentioned above.

[0087] In a more specific embodiment, the induced inlet valve 62 is provided with two inlet valve induction ports 624; the inlet valve induction chamber 625 is simultaneously connected to both inlet valve induction ports 624; one of the inlet valve induction ports 624 is connected to the induction valve control port of the inlet induction valve 64 driven by a solenoid valve or a motor, and the other inlet valve induction port 624 is connected to the induction valve control port of the inlet induction valve 64 driven by manual pressing and the spring force of a switch.

[0088] Two inlet valve induction ports 624 can be provided on the induction type inlet valve 62. One inlet valve induction port 624 is controlled to open and close by a solenoid valve or a motor, and the other inlet valve induction port 624 is controlled to open and close by a manual pressing and a switch spring.
