Detailed Description

To make the objects, technical solutions and advantages of the present invention more apparent, the present invention will be further described in detail with reference to the accompanying drawings.

As shown in fig. 1, the utility model discloses an embodiment of waterfall type washing and hanging toilet stool, which comprises a seat ring panel 1 and a liner bag 2, wherein the seat ring panel 1 is arranged at the top of the liner bag 2.

Referring to fig. 2 and 3, the bladder 2 is provided with a bowl 21, a trapway 22, and a flush feature. Referring to fig. 4, the flushing structure includes a water inlet chamber 23 disposed at the rear end of the toilet bowl 21, and a water guide channel disposed along the periphery of the top of the toilet bowl 21, a water distribution hole communicated with the water inlet chamber 23 is disposed on the top surface of the water guide channel, and a flushing hole 24 communicated with the water inlet chamber 23 is disposed at one end of the water guide channel.

The water guide object comprises a first water guide channel 25 arranged at the rear end of the urinal 21 and second water guide channels 26 continuously arranged at the two sides and the front end of the urinal 21, and a partition 27 is arranged between the first water guide channel 25 and the second water guide channels 26. The first channel 25, the second channel 26, and the partition 27 therebetween form a closed loop around the top perimeter of the bowl 21.

The top surface of the first water guide channel 25 is provided with a plurality of first water distribution holes 28 communicated with the water inlet cavity 23, one end of the second water guide channel 26 is provided with a flushing hole 24 communicated with the water inlet cavity 23, and the top surface of the other end is provided with a second water distribution hole 29 communicated with the water inlet cavity 23. The urinal 21 is provided with a first water baffle 261 and a second water baffle 262 at two ends of the second water guide channel 26, the first water baffle 261 is arranged close to the flushing hole 24, the second water guide plate is arranged close to the second water distribution hole 29, the first water baffle 261 and the second water baffle 262 both extend upwards from the inner wall of the urinal 21, and the first water baffle 261, the second water baffle 262 and the seat panel 1 are all provided with preset distances.

The seat panel 1 is provided with a water guide retainer 11 which extends into the toilet bowl 21 and covers the water guide channel. The water guide channel, the flushing hole 24 and the water distribution hole are all covered by the water guide retaining ring 11 extending into the urinal 21, so that the defect that the holes and the water channel are exposed and easily store dirt and dirt is overcome.

Under the guidance of the second baffle 262 and the second water guide channel 26, some of the water ejected from the second water distribution hole 29 flows along the second water guide channel 26 toward the inner wall of the toilet bowl 21, so as to avoid the problem of insufficient washing water ejected from the flushing hole 24 and flowing along the second water guide channel 26.

The urinal 21 is communicated with the sewage channel 22 through a sewage outlet 212. In this embodiment, a water guide groove 263 is formed between the first water baffle 261 and the second water guide 26 near the flushing hole 24, the water guide groove 263 is located laterally behind the sewage outlet 212, and the end of the water guide groove 263 is communicated with the urinal 21. The second water guide passage 26 and the water guide groove 263 form a stepped structure to guide water. The water guide groove 263 has a short water guide path, and helps to guide the water flowing from the second water guide passage 26 into the toilet bowl 21 to accelerate the formation of vortex washing, thereby enhancing the kinetic energy of vortex washing and improving the washing effect.

Wherein, the aperture of the flushing hole 24 is larger than that of the first water distribution hole 28, and the aperture of the first water distribution hole 28 is larger than that of the second water distribution hole 29.

Thus, the flow rate of water discharged from the flush hole 24 is maximized, and three streams of water flow into the toilet bowl 21. One of the water flows out from the top end of the first water baffle 261, namely a gap between the first water baffle 261 and the seat ring panel 1, and flows into the urinal 21 under the flow guiding effect of the water guiding retainer ring 11 so as to solve the problem of insufficient washing water behind one side of the sewage outlet 212; the other two flows of water flow, a small part of which flows out through the water guide groove 263, and the most of which flows into the toilet bowl 21 through the second water guide passage 26 having a long arc shape above the water guide groove 263.

The water flow discharged from the second water distribution hole 29 positioned at the other side of the toilet bowl 21 is divided into two flows and flows into the toilet bowl 21. One strand of the flushing water flows out from the top end of the second water baffle 262, namely a gap between the second water baffle 262 and the seat ring panel 1, and flows into the urinal 21 under the flow guiding effect of the water guiding retainer ring 11 so as to solve the problem of insufficient washing water behind the other side of the sewage outlet 212; the other flow flows into the urinal 21 along the second water guide channel 26 on the side, and the washing water on the surface of the urinal 21 on the side is supplemented, so that the problem that the washing water which is sprayed from the flushing hole 24 and flows to the position along the second water guide channel 26 is insufficient is avoided.

Referring to fig. 5 and 6, the second water guide channel 26 of the present embodiment is disposed to incline forward and downward to reduce hydraulic loss of water flowing along the front end of the second water guide channel 26, so as to ensure effective washing of the front wall surface of the urinal 21.

In addition, the water flow sprayed from the first water distribution hole 28 located at the rear end of the toilet bowl 21 guides the water to the toilet bowl 21 through the water guide retainer 11.

Therefore, three water flows sprayed from the flushing holes 24, two water flows sprayed from the second water distribution holes 29 and water flows sprayed from the first water distribution holes 28 achieve a 360-degree waterfall type washing effect under the flow guiding effect of the water guide retainer ring 11, the urinal 21 is washed in all directions, no residue is left in washing, and washing uniformity is good.

The water flow jetted from the water guide groove 263 guides the water flow flowing into the toilet bowl 21 from the second water guide passage 26 to accelerate to form vortex washing, so that the vortex kinetic energy is further enhanced, the washing force is strong, and the anti-splash effect is obvious.

In this embodiment, a spiral washing surface 211 is preferably disposed on the urinal 21, the spiral washing surface 211 surrounds the sewage outlet 212 and finally falls into the sewage outlet 212, and the spiral direction of the spiral washing surface 211 from top to bottom is the same as the extending direction of the water guide channel from the flushing hole 24 around the urinal 21. The water flow sprayed from the flushing hole 24 and the spiral flushing surface 211 guide other water flows to form vortex flushing, so that the water flow impact force is enhanced, the flushing force is enhanced by utilizing the kinetic energy of the vortex flushing, the flushing effect is improved, and meanwhile, the problem that the water flow directly collides at the sewage outlet 212 to generate water splashing in the flushing process of the prior art is solved.

To facilitate the dirt to fall into the trapway 22 with spin, the orthogonal projection width of the spiral washing surface 211 of this embodiment decreases from top to bottom.

With reference to fig. 7 and 8, the rear wall of the urinal 21 of the present embodiment is provided with two sections, specifically, an arc section 213 at the upper part and an inclined section 214 at the lower part.
