[0028] Figure 1 A schematic diagram of a toilet provided in an embodiment of the present invention is shown; Figure 2 A schematic diagram of the flushing device provided in an embodiment of the present invention is shown; Figure 3 A top view of the flushing device provided in an embodiment of the present invention is shown. (Refer to...) Figures 1-3 This embodiment provides a flushing device and a toilet.

[0029] The toilet includes a ceramic body 10 and a flushing device provided in this embodiment. The ceramic body 10 has an independent bowl 11 and a receiving space 12. A portion of the flushing device is disposed in the receiving space 12, and another portion of the flushing device extends into the bowl 11.

[0030] The flushing device includes a flush pump 100, a brush ring outlet pipe assembly 200, a main outlet pipe assembly 300, a water tank 400, and an inlet valve 500. The water tank 400 is disposed within the receiving space 12 and contains water. The flush pump 100 is disposed within the water tank 400. The inlet valve 500 connects the water tank 400 and the water supply source and is configured to control the on / off connection between the water supply source and the water tank 400. In this embodiment, the water supply source can specifically be the toilet's inlet pipe. The brush ring outlet pipe assembly 200 and the main outlet pipe assembly 300 respectively deliver water from the flush pump 100 to the toilet bowl 11.

[0031] Specifically, the water tank 400 also includes a locking assembly 410. A connecting wing plate is provided on the side of the water tank 400, which overlaps the side edge of the receiving space 12 and is locked to the ceramic body 10 by the locking assembly 410. In this embodiment, the locking assembly 410 can specifically be a combination of a bolt and a nut. The bolt passes through the connecting wing plate and the side edge of the receiving space 12, and the nut is locked to the bolt from inside the ceramic body 10, thus fixing the water tank 400 in the receiving space 12.

[0032] Figure 4A schematic diagram of the interior of the water tank of the flushing device provided in an embodiment of the present invention is shown. (Refer to...) Figure 3 and Figure 4 The water tank 400 also includes a bracket 420. The bracket 420 is configured to support and secure the flushing pump 100. The bracket 420 is fixed to the bottom of the water tank 400 and has an installation opening through which the flushing pump 100 passes and is fixedly installed. Optionally, in this embodiment, the bracket 420 may be made of rubber. This design ensures the reliability and stability of the flushing pump 100's installation in the water tank 400, and the rubber bracket 420 provides cushioning for the flushing pump 100, reducing its operating noise.

[0033] Figure 5 A schematic diagram of a flushing pump provided in an embodiment of the present invention is shown. (Refer to...) Figure 4 and Figure 5 The flushing pump 100 includes an inlet structure 110, a brush ring outlet structure 120, a main flush outlet structure 130, and a pump body 140. Water entering the pump body 140 from the inlet structure 110 can be flushed out from the brush ring outlet structure 120 and the main flush outlet structure 130.

[0034] Specifically, the water inlet structure 110, the brush ring water outlet structure 120, and the main flush water outlet structure 130 are respectively connected to the pump body 140 of the flush pump 100. The brush ring water outlet structure 120 and the main flush water outlet structure 130 are arranged parallel to each other and spaced apart. The axial direction of the water inlet structure 110 forms an angle with the axial direction of the brush ring water outlet structure 120 and is located between the brush ring water outlet structure 120 and the main flush water outlet structure 130. The water inlet structure 110 is connected to the internal space of the water tank 400. The inlet of the brush ring water outlet pipe assembly 200 is connected to the brush ring water outlet structure 120, and the outlet of the brush ring water outlet pipe assembly 200 is connected to the toilet bowl 11. The inlet of the main flush water outlet pipe assembly 300 is connected to the main flush water outlet structure 130, and the outlet of the main flush water outlet pipe assembly 300 is connected to the toilet bowl 11, and is arranged at intervals with the outlet of the brush ring water outlet pipe assembly 200 along the length direction of the toilet bowl 11. The water flushed through the brush ring water outlet structure 120 can pre-wet the toilet bowl or replenish the toilet bowl after flushing, while the water flushed through the self-flushing water outlet structure 130 can flush and clean the waste in the toilet bowl 11.

[0035] Preferably, the outlet of the brush ring water outlet assembly 200 is located on one side of the rear end along the length of the toilet bowl 11, and the water flowing out of the outlet of the brush ring water outlet assembly 200 can flow along the surface of the toilet bowl 11 in a swirling state. The outlet of the main water outlet assembly 300 is located at the middle of the front end along the length of the toilet bowl 11, directly opposite the drain outlet of the toilet bowl 11, and the water flowing out of the outlet of the main water outlet assembly 300 can directly flush the waste in the toilet bowl 11 to the drain outlet.

[0036] More specifically, the brush ring water outlet pipe assembly 200 includes a pump brush ring water outlet pipe 210, a brush ring pipe 220, and a first clamp 230. The pump brush ring water outlet pipe 210 is located in the water tank 400, connected to the brush ring water outlet structure 120, and extends out of the water tank 400. It is reliably connected to the brush ring pipe 220 by the first clamp 230. The brush ring pipe 220 extends to one side of the rear end in the length direction of the toilet bowl 11 to discharge brush ring water.

[0037] Preferably, the flushing device further includes a foaming component 600. This foaming component 600 is disposed in the water outlet path of the brush ring water outlet structure 120, and can mix the foaming agent with water to generate foam, which is then released into the toilet bowl 11 through the brush ring water outlet structure 120. By providing the aforementioned foaming component 600, a foam shield function for the toilet brush ring can be formed. The aforementioned foaming component 600 is prior art, and its structure and principle will not be described in detail in this embodiment.

[0038] More specifically, the main water outlet pipe assembly 300 includes a pump main water outlet pipe 310, a main water outlet pipe 320, and a second clamp 330. The pump main water outlet pipe 310 is located in the water tank 400, connected to the main flush outlet structure 130, and extends out of the water tank 400. It is reliably connected to the main water outlet pipe 320 using the second clamp 330. The main water outlet pipe 320 extends to the front end of the toilet bowl 11 along its length, and a main flush nozzle is provided at its outlet, which can pressurize the water flow.

[0039] Figure 6 This diagram illustrates the swirling direction of water when the flushing pump provided in the embodiment of the present invention is in the first rotation mode; Figure 7 This diagram illustrates the swirling direction of water when the flushing pump provided in an embodiment of the present invention is in its second rotation mode. (Refer to...) Figures 5-7 The pump body 140 has a cylindrical structure. The brush ring water outlet structure 120 and the main flush water outlet structure 130 are respectively arranged along the tangential direction of the pump body 140. Both the brush ring water outlet structure 120 and the main flush water outlet structure 130 extend upward in the direction of gravity. The axial direction of the water inlet structure 110 is perpendicular to the axial direction of the brush ring water outlet structure 120.

[0040] Specifically, during the flushing process, the flushing pump 100 can switch between a first rotation mode and a second rotation mode. By switching between these modes, functions such as toilet bowl pre-wetting, waste flushing, and post-flushing toilet bowl refilling can be achieved. When the flushing pump 100 is in the first rotation mode, the brush ring water outlet structure 120 is located downstream of the main flushing water outlet structure 130 in the direction of water swirl within the pump body 140. When the flushing pump 100 is in the second rotation mode, the brush ring water outlet structure 120 is located upstream of the main flushing water outlet structure 130 in the direction of water swirl within the pump body 140.

[0041] In this first rotation mode, the water in the pump body 140 first flows through the main flush outlet structure 130 in the swirling direction. Under the action of tangential force, most of the water enters the main flush outlet structure 130 and flows out to the toilet bowl 11, thus flushing away waste. A small portion of the water flows to the brush ring outlet structure 120 and then flows into the toilet bowl 11, thus pre-wetting the toilet bowl or replenishing water after flushing. In other words, in this first rotation mode, the water flow rate of the main flush outlet structure 130 is greater than the water flow rate of the brush ring outlet structure 120.

[0042] In this second rotation mode, the water in the pump body 140 first flows through the brush ring water outlet structure 120 in the swirling direction. Under the action of tangential force, most of the water enters the brush ring water outlet structure 120 and flows out to the toilet bowl 11, realizing the function of pre-wetting the toilet bowl or replenishing water after flushing. A small portion of the water flows to the main flush water outlet structure 130 and flows out to the toilet bowl 11. That is to say, in this second rotation mode, the water flow rate of the brush ring water outlet structure 120 is greater than the water flow rate of the main flush water outlet structure 130.

[0043] More specifically, since the water volume required for the toilet pre-wetting function and the toilet water replenishment function after flushing is relatively small, the effective water outlet cross-sectional area of ​​the brush ring water outlet structure 120 is designed to be smaller than the effective water outlet cross-sectional area of ​​the main flush water outlet structure 130.

[0044] More specifically, during the flushing process, the duty cycle of the flushing pump 100 in the first rotation mode is greater than the duty cycle of the flushing pump 100 in the second rotation mode. The duty cycle refers to the proportion of the high-level signal within one pulse cycle, which can be understood as the operating power of the flushing pump 100. Within the rated power range of the flushing pump 100, the larger the duty cycle, the greater the operating power of the flushing pump 100, and the greater the impact force and water volume of a single flush; conversely, the smaller the duty cycle, the smaller the operating power of the flushing pump 100, and the smaller the impact force and water volume of a single flush. By setting different duty cycles for different rotation modes, different water flow rates and impact forces can be provided in different modes to meet different usage scenarios, effectively saving water while ensuring flushing performance.

[0045] This embodiment also provides a flushing control method, which controls the flushing process based on the toilet provided in this embodiment. The flushing control method includes a flushing function control method and a brush seat foaming function control method. The flushing function control method includes: S10. Start the flushing process, control the flushing pump 100 to start, and enter the second rotation mode; S20. After the flushing pump 100 has been in the second rotation mode for a first preset time, the flushing pump 100 is controlled to enter the first rotation mode. S30. After the flushing pump 100 has been in the first rotation mode for a second preset time, the flushing pump 100 is controlled to enter the second rotation mode again. S40. After the flushing pump 100 reaches the third preset time in the second rotation mode, the flushing process stops. And / or, The flushing device also includes a foaming component 600, which mixes a foaming agent with water in the water outlet path of the brush ring water outlet structure 120 to generate foam, and then discharges the foam into the toilet bowl 11 through the brush ring water outlet structure 120. The method for controlling the foaming function of the brush ring includes: The foaming function of the foaming component 600 is activated, foam liquid is generated in the foaming component 600, and the flushing pump 100 is started and enters the second rotation mode, so that the brush ring water outlet structure 120 performs foaming for a fourth preset time.

[0046] In this embodiment, the second preset duration is longer than the first preset duration, and the second preset duration is longer than the third preset duration. The specific values ​​of the first, second, and third preset durations can be designed and selected according to different parameters of the toilet, or can be set by the user through remote control or control panel, etc. The specific values ​​are not limited in this embodiment.

[0047] Furthermore, in step S10 of this embodiment, the flushing pump 100 operates at a first duty cycle; in step S20, the flushing pump 100 operates at a second duty cycle, which is greater than the first duty cycle; in step S30, the flushing pump 100 operates at a third duty cycle, which is less than the second duty cycle.

[0048] It should be noted that, in another embodiment, in step S20, the flushing pump 100 first operates at the second duty cycle. Subsequently, within the second preset time range, the duty cycle of the flushing pump 100 gradually increases, and stops increasing after reaching the rated power. At this time, the water flow through the brush ring water outlet structure 120 increases, that is, the large water flow from the brush ring water outlet structure 120 and the large water flow from the main flushing water outlet structure 130 can be used simultaneously to flush away dirt, thereby further improving the dirt flushing effect and efficiency.

[0049] Preferably, when the toilet is first powered on or after a power outage and then powered on again, the following steps are performed before the flush pump 100 starts: The foaming function of the foaming component 600 is activated, and foam liquid is generated in the foaming component 600. After the foaming time is preset, the foaming function of the foaming component 600 is stopped, and then the flushing process is started.

[0050] It should be noted that the flushing function and the bubble-generating function are two independent functions and can be used separately.
