[0022] Embodiment 1

[0023] Reference Figure 1 and Figure 2 As shown, this embodiment provides a cleaning water channel mechanism for a toilet, including a first water channel 10, a second water channel 20, a booster pump 40 and an output water channel 30. The first water channel 10 is provided with a water tank 11, and the water tank 11 is provided with a heater 12. Specifically, the water tank 11 is used to store a certain amount of water, and the heater 12 is used to heat the water in the water tank 11, so that a certain amount of hot water can be pre-stored in the water tank 11. The second water circuit 20 is provided with an instant heater 21; the output ends of the first water circuit 10 and the second water circuit 20 are both connected to the input end of the booster pump 40. For example, in this embodiment, the output end of the first water circuit 10, the output end of the second water circuit 20 and the input end of the booster pump 40 are connected through a three-way pipe; the output end of the booster pump 40 is connected to the output water circuit 30, and the output water circuit 30 is used to connect the spray rod 100 of the toilet. In this way, the first water circuit 10 and the second water circuit 20 are connected in parallel, and the output water of the first water circuit 10 and the second water circuit 20 are mixed and flow into the output water circuit 30, and are uniformly output by the output water circuit 30. The output water circuit 30 is provided with a first temperature sensor 31, and the output end of the first temperature sensor 31 is connected to a controller 60, and the control end of the controller 60 is connected to the instant heater 21, so that temperature feedback is formed.

[0024] This embodiment further provides a toilet, in which the above-mentioned flushing water channel mechanism of the toilet is used to supply water, that is, the output water channel 30 is connected to the spray rod 100 of the toilet.

[0025] When cleaning is started, the booster pump 40 simultaneously draws water from the first water channel 10 and the second water channel 20. Specifically, the first water channel 10 is supplied with water by the water tank 11, which provides hot water pre-heated by the heater 12, while the second water channel 20 directly supplies external cold water. The water from the first water channel 10 and the second water channel 20 are mixed and then increased by the booster pump 40 and transported to the output water channel 30, which is then output to the spray rod 100. During the process, the first temperature sensor 31 detects the water temperature of the output water channel 30 and feeds it back to the controller 60. The controller 60 controls the instantaneous heater 21 of the second water channel 20 to work according to the water temperature data detected by the first temperature sensor 31, so as to achieve temperature control. The specific method is as follows: when the water temperature detected by the first temperature sensor 31 is not lower than the preset value, the instantaneous heater 21 of the second water channel 20 does not work; when the first temperature sensor 31 is When the water temperature detected by the temperature sensor 31 is lower than the preset value, the controller 60 controls the instant heater 21 of the second water circuit 20 to work, and the instant heater 21 starts to heat the water in the second water circuit 20. After that, the controller 60 adjusts the power of the instant heater 21 according to the real-time temperature detected by the first temperature sensor 31. In this way, the first water circuit 10 is set to store hot water in advance, and then the temperature difference is supplemented by the instant heater 21 during the cleaning process, thereby ensuring that a larger flow rate and output water that meets the set temperature are provided under lower power; it can well meet general household uses.

[0026] Furthermore, the first water channel 10 is provided with a one-way valve 50 at the rear end of the water tank 11, and the second water channel 20 is also provided with a one-way valve 50 at the rear end of the instant heater 21. The one-way valve 50 can prevent water from flowing back. Of course, in other embodiments, the first water channel 10 or the second water channel 20 may not be provided with a one-way valve 50.

[0027] Furthermore, the water tank 11 is provided with a second temperature sensor 14, the output end of the second temperature sensor 14 is connected to the controller 60, and the control end of the controller 60 is also connected to the heater 12. The second temperature sensor 14 detects the water temperature in the water tank 11 and outputs it to the controller 60. The controller 60 controls the heater 12 to work according to the actual water temperature in the water tank 11. For example, when the water temperature in the water tank 11 is too low, the heater 12 is controlled to heat. When the water temperature in the water tank 11 reaches a preset value (the preset value of the water temperature in the water tank 11 is different from the preset value of the output water in the output waterway 30), the heater 12 is controlled to stop heating. In this way, the heating of the water tank 11 also forms a temperature feedback, which can well control the water temperature in the water tank 11 and better ensure the water temperature of the final output water.

[0028] The first water circuit 10 is provided with a first water inlet valve 16 at the front end of the water tank 11, and a water level sensor 13 is provided in the water tank 11. The output end of the water level sensor 13 is connected to the controller 60, and the control end of the controller 60 is connected to the first water inlet valve 16. In this way, when the water level sensor 13 detects that the water level in the water tank 11 is low, the controller 60 can control the opening of the first water inlet valve 16 to replenish water, and then close the first water inlet valve 16 after the water level reaches the set level.

[0029] Specifically, in this embodiment, the water tank 11 is a non-pressure-bearing water tank, and a pressure relief hole 15 is provided on the water tank 11. More specifically, the pressure relief hole 15 can be actively controlled by the controller 60, such as installing a pressure relief valve on the pressure relief hole 15, and when the water level sensor 13 detects that the water level is too high, the controller 60 controls the pressure relief valve to open. It can also automatically release pressure according to its own pressure-bearing size, such as installing a pressure-bearing part on the pressure relief hole 15, and when the water pressure is greater than the pressure-bearing size of the pressure-bearing part itself, the pressure-bearing part cannot continue to bear the pressure and releases the pressure.

[0030] The second water circuit 20 is provided with a second water inlet valve 22 at the front end of the instant heater 21, and the control end of the controller 60 is connected to the second water inlet valve 22. The second water inlet valve 22 is provided to better control the on-off of the second water circuit 20. Of course, in other embodiments, the second water circuit 20 may not be provided with the second water inlet valve 22, and the on-off of the second water circuit 20 may also be controlled by an external water inlet circuit.

[0031] Specifically, in this embodiment, the structures and connection structures of electrical components such as the first temperature sensor 31, the second temperature sensor 14, the water level sensor 13, the heater 12, the instant heater 21 and the controller 60 are all prior arts and will not be described in detail here.

[0032] Embodiment 2

[0033] The flushing water channel mechanism of a toilet provided in this embodiment is substantially the same in structure as the flushing water channel mechanism of the first embodiment, except that: in this embodiment, the water tank 11 is a pressure-bearing water tank, which can withstand a certain water pressure, and therefore, there is no need to set a pressure relief hole 15 structure as in the first embodiment. The pressure-bearing water tank can also output water with a relatively high water pressure, and therefore, the power of the booster pump 40 is also reduced to a certain extent.

[0034] The present embodiment provides a toilet, which uses the flushing water channel mechanism of the toilet described in the present embodiment to supply water.

[0035] Although the present invention has been specifically demonstrated and described in conjunction with the preferred embodiments, those skilled in the art should understand that various changes may be made to the present invention in form and detail without departing from the spirit and scope of the present invention as defined in the appended claims, all of which are within the scope of protection of the present invention.
