  • Male and female users are known to have different practices after urination. Those who do not use toilet paper after urination are usually male users, and those who use toilet paper after urination are usually female users. Male users flush directly after each urination, and female users need toilet paper after urination is over, so this means female users need more water to flush the toilet paper in the toilet. Water savings for urine flushing for male users are about 50% compared to female users, as there is no need to flush toilet paper with water, and the flushing water simply flushes the ceramic surface and refills the siphon.
  • the suction-type toilet 100 of the embodiment of the present disclosure divides flushing for liquids into two flushing modes, in which the first flushing mode is suitable for flushing for liquids without paper for men, and the second flushing mode is suitable for flushing for liquids with paper for women.
  • the user presses a button with a male flush operation (for example, the button may be prompted by the symbol M) to trigger a first flushing command (for example, a low voltage pulse signal).
  • the control device 24 of the flushing system receives the first flushing command, activates the suction device 12 to suck out the excrement, and the backflow prevention valve 13 is automatically opened.
  • the suction device 12 is stopped after being activated for a first predetermined emptying time, the backflow prevention valve 13 is closed to prevent water from the sewer from flowing back to the water sealing zone 106 of the toilet.
  • the liquid level of the toilet body 1 can be estimated by opening time of the first electric control valve 23 a, or can be detected by providing a liquid level sensor in the toilet body 1, which is not limited here.
  • an initial basic water level L1 is in the toilet bowl.
  • the water level rises to LM, and the user presses the flush button to directly perform suction and emptying.
  • the toilet is flushed and filled with the water level to L1.
  • a main purpose for setting the stop time is to start the filling process only after a process of sucking away the excrement is completely completed. There needs to be a short gap time in the middle, otherwise a suction pump will not know when to stop.
  • the second flushing mode is suitable for flushing for liquids with paper for women, and its specific operation method is as follows.
  • the control device 24 receives the second flushing command, controls the first electric control valve 23a to open the first spray washing pipeline 21, and about 400 ml of water is sprayed from the first nozzle 210.
  • the first nozzle 210 is installed at the front portion of the toilet bowl 10 close to the front wall of the toilet, so that the toilet paper enters the lower portion of the toilet bowl 10 from the front portion of the toilet bowl 10 to flush the toilet paper to the water sealing zone part of the toilet bowl 10.
  • the water level rises to a second predetermined liquid level L2, the paper in the toilet bowl 10 can float on the water surface, and the water level in the toilet bowl 10 is higher than a lower end position of the rear slope portion 105 of the toilet bowl 10.
  • the control device 24 controls the suction device 12 to turn on, and the suction device 12 sucks out the liquid with the floating toilet paper.
  • the suction device 12 is stopped after operation of the suction device 12 is started for a third predetermined emptying time, and after the suction device 12 is started and before the suction device 12 is stopped, the control device 24 controls the first electric control valve 23a to close.
  • the suction device 12 and the first spray washing pipeline 21 operate simultaneously for a period of time.
  • the suction device 12 When the water in the toilet bowl 10 is evacuated, the suction device 12 is stopped, and the control device 24 controls the first electric control valve 23a to open again to open the first spray washing pipeline 21 until the water level of the water sealing zone 106 reaches the first predetermined liquid level L1, about 200 milliliters of water to cover components of the suction device 12 in contact with the excrement.
  • the backflow prevention valve 13 is closed to prevent gas from the waste water pipe from entering. Please refer to Table 2 for a specific control process.
  • an initial basic water level L1 is in the toilet bowl. After the user uses the toilet, the water level rises to LF. The user presses the flush button to perform flushing, the water level rises to L2, suction and emptying are performed, and after a short time, the toilet is flushed and filled with the water level to L1.
  • the first spray washing pipeline 21 is controlled to be opened, and the first spray washing pipeline 21 is closed when the water in the toilet bowl 10 reaches the second predetermined liquid level.
  • the first spray washing pipeline 21 or the second spray washing pipeline 22 is controlled to be opened to replenish the toilet bowl 10 with water, and the first spray washing pipeline 21 or the second spray washing pipeline 22 is closed when the water in the toilet bowl 10 reaches the first predetermined liquid level L1.
  • Water consumption analysis for the second flushing mode is as follows: approximately 400 ml of water for flushing the paper, approximately 200 ml of water for refilling the bottom of the toilet bowl, and a total amount of emptying of approximately 800 ml (including approximately 200 ml of urine).
  • the suction-type toilet 100 of the embodiment of the present disclosure is also provided with a third flushing mode, which is suitable for use by male or female after excretion of solid feces.
  • the flushing system of the embodiment of the present disclosure can be all integrated into one box body D.
  • the flushing system is used for a plurality of toilets, at least the control panel cannot be integrated into the box body, and a plurality of panels need to be provided corresponding a plurality of toilets for user operation, which can realize an integrated, pre-installed one-piece design, which is plug and play, can be placed on the floor, or can be installed on a wall of a room.
  • the design is easy to install while allowing one flushing system to be applied to the plurality of toilets.
