Detailed implementation manners

[0024] Now, the exemplary embodiments will be described more comprehensively with reference to the drawings. However, the exemplary embodiments can be implemented in various forms and should not be construed as limited to the embodiments set forth herein; on the contrary, these embodiments are provided so that this application will be thorough and complete, and the concept of the exemplary embodiments will be fully conveyed to those skilled in the art. The same reference numerals in the drawings denote the same or similar structures, and thus their detailed descriptions will be omitted.

[0025] Refer to Figures 1 to 5 , in one embodiment, the switching device 100 includes a valve housing 10 and a water sealing member 20. A valve cavity 11, a water inlet passage 12, and at least two water outlet passages 13 are formed in the valve housing 10. The water inlet passage 12 and the water outlet passages 13 are respectively communicated with the valve cavity 11. The water sealing member 20 is arranged in the valve cavity 11 in a rotatable manner to control the on-off of the water outlet passages 13. An anti-siphon device (not shown) is provided upstream of the water inlet passage 12.

[0026] Preferably, the valve housing 10 includes a main body 14, a sealing cover 40, and a driving mounting cover 50. The main body 14 may adopt a cylindrical-like structure, and a valve chamber 11 is formed inside the main body 14. An inlet pipe portion 15 and at least two outlet pipe portions 16 are provided on the circumferential surface of the main body 14. An inlet water passage 12 is formed inside the inlet pipe portion 15, and an outlet water passage 13 is formed inside each outlet pipe portion 16. One end of the main body 14 is provided with an opening that communicates with the valve chamber 11, and the water sealing member 20 can be inserted into the valve chamber 11 from the opening. The sealing cover 40 and the driving mounting cover 50 are sequentially sealed at the opening.

[0027] Preferably, the switching device 100 further includes a driving member 30. The driving member 30 is mounted on the driving mounting cover 50. The output shaft of the driving member 30 extends into the valve chamber 11, and the driving member 30 is connected to the water sealing member 20. The driving member 30 can be a knob, a motor, or other forms of driving. In the embodiment, the driving member 30 is selected as a motor.

[0028] See Figure 3 and Figure 4 In the embodiment, an avoidance position and a blocking position are provided inside the valve housing 10. When the water sealing member 20 rotates to the avoidance position, at least two outlet water passages 13 remain in communication with the valve chamber 11, that is, at least two outlet water passages 13 can discharge water, improving the flushing effect. When the water sealing member 20 rotates to the blocking position, at least one outlet water passage 13 is blocked from communicating with the valve chamber 11, and at least one outlet water passage 13 remains in communication with the valve chamber 11.

[0029] Preferably, one of the outlet water passages 13 is a flushing passage that communicates with the flushing water path 400 of the toilet 1, and the other outlet water passage 13 is a down-flushing passage that communicates with the down-flushing water path 500 of the toilet 1. When the water sealing member 20 is in the avoidance position, the flushing passage and the down-flushing passage are simultaneously in communication, and the water flow enters through the inlet water passage 12 and passes through the valve chamber 11, and can discharge water simultaneously through the two paths of the flushing passage and the down-flushing passage, solving the problem that the flushing effect is poor without flushing during down-flushing. When the water sealing member 20 is in the blocking position, the down-flushing passage does not discharge water, and the flushing passage discharges water. Preferably, the avoidance position is located on the chamber wall of the valve chamber 11 opposite to the flushing passage, and the blocking position can be the inlet of the outlet water passage 13. In the embodiment, the blocking position is set at the inlet of the down-flushing passage. In other embodiments, see Figure 5 , the avoidance position may also be located on the chamber wall of the valve chamber 11 adjacent to the flushing passage, and both ends of the water blocking piece 21 are respectively close to the inner wall of the flushing passage and the inner wall of the down-flushing passage.

[0030] In an embodiment, the water sealing member 20 includes a rotating shaft portion 22 and a water blocking piece 21. The rotating shaft portion 22 is connected to the driving member 30, and the water blocking piece 21 is provided on the rotating shaft portion 22 and can rotate with the rotating shaft portion 22. In the avoidance position, both ends of the water blocking piece 21 are respectively connected to the inner walls of the water inlet passage 12 and the downward flushing passage, so as to avoid the water having to impact the water blocking piece 21, resulting in unsmooth water flow. Preferably, both ends of the water blocking piece 21 are respectively connected to the rotating shaft portion 22, and a hollow channel is formed between the inner wall of the water blocking piece 21 and the rotating shaft portion 22 to facilitate the water flow through. When the water blocking piece 21 is in the avoidance position, both the downward flushing passage and the washing passage are opened. When the water blocking piece 21 is in the blocking position, the water blocking piece 21 blocks the downward flushing passage and the washing passage is opened.

[0031] See Figure 1 , in some embodiments, a toilet 1 includes the above-mentioned switching device 100, water tank 200 and pump 300. The pump 300 is connected to the water tank 200 and the water inlet passage 12, and the pump 300 drives the water in the water tank 200 to flow into the water inlet passage 12. The water tank 200 and the pump 300 can be connected by a hose. The pump 300 and the water inlet pipe portion 15 can also be connected by a hose. The water outlet pipe portion 16 and the toilet seat 1 can also be connected by a hose or other structures. Preferably, when the toilet 1 flushes, the water sealing member 20 first moves to the blocking position and then moves to the avoidance position. First, a washing process is performed, and then downward flushing and washing are carried out. The washing passage is always in an open state, which significantly improves the flushing effect.
