DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENT

[0017] The purpose, construction, features, functions and advantages of the present invention can be appreciated and understood more thoroughly through the following detailed descriptions with reference to the attached drawings.

[0018] Refer to FIG. 1 for a schematic diagram of a low-noise pressure flushing system according to the present invention. As shown in FIG. 1, the low-noise pressure flushing system includes: a flush valve 10; a first flush tube 21, connected to a water output end of the flush valve 10; a second flush tube 22, connected to the water output end of the flush valve 10; and a check valve 30, disposed at a water output end of the first flush tube 21.

[0019] Then, refer to FIGS. 2, 3, and 4 respectively for a schematic diagram of a toilet device 100 according to the present invention; a schematic diagram of another toilet device 100 according to the present invention, and an exploded view of a check valve according to the present invention. As shown in FIGS. 2, 3, and 4, in an embodiment of the present invention, the low-noise pressure flushing system further includes: a seat body 40, wherein, the first flush tube 21 is connected to a water input end of a first flush port 51 located above the seat body 40, and the second flush tube 22 is connected to a water input end of a second flush port 52 located below the seat body 40.

[0020] In an embodiment of the present invention, the low-noise pressure flushing system further includes a siphon 41, a water output end of the second flush port 52 is used to eject water directly onto an opposite and ascending section of the siphon 41 for the seat body 40. As such, the water output end of the second flush port 52 is in the water ejection of the siphon 41 (the water output end of the second flush port 52) is full of water, such that the water ejected may produce siphon effects immediately.

[0021] In an embodiment of the present invention, the low-noise pressure flushing system further includes: a flush connector main body 60 and a tightening nut 70. The flush connector main body 60 is disposed at the first flush port 51, and outer threads 61 are provided at a perimeter of the flush connector main body 60. The tightening nut 70 is used to connect the flush connector main body 60 to the first flush tube 21, and the check valve 30 is disposed between the flush connector main body 60 and the tightening nut 70.

[0022] In addition, the present invention further provides a toilet device 100 including and utilizing the low-noise pressure flushing system as mentioned above, and the toilet device further includes a toilet bowl 80, a toilet seat ring 81, and a toilet seat cover 82. The toilet bowl 80 is made of ceramics, to form an outer shell of the toilet device. The toilet seat ring 81 is made of plastic, such that when the toilet device is in use, the toilet seat ring 81 is placed on a top of the toilet bowl 80, for a user to seat thereon. The toilet seat cover 82 is made of plastic, such that when the toilet device is not in use, the toilet seat cover 82 is placed on the toilet seat ring 81, to prevent bad smells from leaking out of the toilet bowl 80, and to prevent objects from falling into the toilet bowl 80.

[0023] The major technical characteristics of the present invention are as follows:

[0024] 1. There are two water output ports in the low-noise pressure flushing system, namely the water output ports of the first flush tube 21 and the second flush tube 22, connected respectively to the lip ring flush port (first flush port 51) and the ejection flush port (the second flush port 52) of the toilet device 100.

[0025] 2. The check valve 30 is disposed in the connector of the lip ring flush port for preventing the reverse flow of the air. Since the water channels in the first flush tube 21 and the second flush tube 22 are connected and in communication, so air is not allowed to enter into the second flush tube 22. As such, in water flushing, there is no need to expel and empty the air from the two water channels (the action of expelling and emptying the air is the main reason for a pressure flushing system to produce noise). The results of the tests for mute or silence effect conducted for the low-noise pressure flushing system prove to be excellent.

[0026] 3. The second flush port 52 located at the bottom portion of the seat body 40 of the toilet device 100 is disposed inside a water retaining bend of the seat body 40, such that water is ejected from the second flush port 52 directly onto the opposite and ascending section of the siphon 41. Therefore, siphon effect can be produced quickly in the siphon 41, meanwhile, the high pressure fast speed water jet coming from the ejection hole tends not cause the water in the water retaining bend to be splashed out of the toilet, to reduce the flushing noise significantly. Since the water in the water retaining bend is suctioned out through the siphon effect inside, the contaminants and the micro bacteria in the water retaining bend will not be flushed into the air.

[0027] The above detailed description of the preferred embodiment is intended to describe more clearly the characteristics and spirit of the present invention. However, the preferred embodiments disclosed above are not intended to be any restrictions to the scope of the present invention. Conversely, its purpose is to include the various changes and equivalent arrangements which are within the scope of the appended claims.
