[0002] A toilet usually includes a water tank, a barrel, a water inlet channel connecting the barrel and the water tank, and a sewage pipe connected to the inner cavity of the barrel. For example, a Chinese patent with publication number CN117211380A discloses a toilet with a water-saving function, including a toilet body and a water tank; the water tank is fixed to the toilet body. An inlet valve, a drain valve and an overflow pipe are provided inside the water tank; a drain hole is provided at the bottom of the water tank, and the toilet body is provided with an annular guide channel connected to the drain hole, and a plurality of water outlets are provided in sequence on the annular guide channel. Since the flushing cleanliness of the toilet body is related to the flushing flow rate, the aperture of the drain hole of the above-mentioned toilet does not change, resulting in the flow rate of the tap water entering the annular guide channel unchanged, or even slowed down, affecting the flushing effect of the toilet body. In view of this, the utility model proposes a direct flush toilet to solve the above problems. Utility Model Content

[0003] The utility model overcomes the shortcomings of the above-mentioned technology and provides a direct flush toilet. In order to achieve the above-mentioned purpose, the utility model adopts the following technical solutions:

[0004] A direct-flush toilet comprises a toilet seat, the toilet seat is provided with a barrel body, a seat ring located at the top of the barrel body, and a sewage pipe located at the bottom of the barrel body, an annular water channel is provided in the seat ring, and the seat ring is provided with a flushing hole connected to the annular water channel, a water tank is connected to the top of the toilet seat, a first water outlet and a drainage valve for opening and closing the first water outlet are provided at the bottom of the water tank, the first water outlet is connected to the annular water channel through a water inlet pipe, and the water inlet pipe is inclined upward from the first water outlet to the annular water channel and the width of the water inlet pipe gradually decreases.

[0022] The following examples further illustrate the features of the present invention and other related features to facilitate understanding by those skilled in the art:

[0023] Reference Figure 1-5 , an embodiment of a direct flush toilet of the utility model is proposed:

[0024] A direct flush toilet includes a toilet seat 1. The toilet seat 1 is provided with a barrel body 2, a seat ring 3 located at the top of the barrel body 2, and a sewage pipe 6 located at the bottom of the barrel body 2. An annular waterway 31 is provided in the seat ring 3, and a flushing hole 32 connected to the annular waterway 31 is provided in the seat ring 3. A water tank 4 is connected to the top of the toilet seat 1, and a first water outlet 41 and a drainage valve (not shown in the drawings) for opening and closing the first water outlet 41 are provided at the bottom of the water tank 4. The first water outlet 41 is connected to the annular waterway 31 through a water inlet pipe 5, and the water inlet pipe 5 is inclined upward from the first water outlet 41 to the annular waterway 31, and the width of the water inlet pipe 5 gradually decreases.

[0025] The tap water in the water tank 4 enters the water inlet pipe 5 from the first water outlet 41. Since flow rate = flow velocity·cross-sectional area, the width of the water inlet pipe 5 of the utility model gradually decreases from the first water outlet 41 to the annular water channel 31. When the flow rate is equal, the smaller the width (cross-sectional area) of the water inlet pipe 5, the greater the flow velocity. The flow velocity of the tap water coming out of the water tank 4 increases after passing through the water inlet pipe 5. The high flushing flow velocity is conducive to flushing the inner wall of the barrel body 2.

[0026] In addition, when the toilet is not in use, if the drain valve is not closed tightly or the seal is poor, the tap water in the water tank 4 will flow into the water inlet pipe 5. Since the water inlet pipe 5 is inclined upward from the first water outlet 41 to the annular water channel 31, the water inlet pipe 5 can temporarily store tap water for the next toilet flushing, thereby achieving the purpose of saving water.

[0027] like Figure 1 As shown, the toilet seat 1 includes a seat surface 11 and a side wall 12 arranged around the seat surface 11 , and the water tank 4 is installed on the seat surface 11 .

[0028] like Figure 5 As shown, the top of the water inlet pipe 5 is an upper plane 51, which is parallel to the seat surface 11 and connected to the bottom of the seat surface 11. The upper plane 51 is provided with a water inlet 511 opposite to the first water outlet 41; the seat surface 11 is provided with a through hole opposite to the first water outlet 41. The bottom of the water inlet pipe 5 is a lower inclined surface 52, which is inclined upward from the first water outlet 41 to the annular water channel 31. One end of the water inlet pipe 5 is a second water outlet 53 connected to the annular water channel 31, and the other end of the water inlet pipe 5 is closed.

[0029] like Figure 3As shown, the tap water in the water tank 4 can directly reach the water inlet pipe 5 through the first water outlet 41, the through hole, and the water inlet 511 in sequence. There is no need for a bend pipe to connect the water inlet pipe 5 and the first water outlet 41, and the structure is simpler.

[0030] like Figure 4 As shown, the seat ring 3 includes an upper annular surface 33, a lower annular surface 34 located inside the barrel body 2, and a side annular surface 35 connecting the upper annular surface 33 and the lower annular surface 34. The outer edge of the upper annular surface 33 is connected to the top of the barrel body 2. There is a gap between the lower annular surface 34 and the inner wall of the barrel body 2. The lower annular surface 34 is evenly provided with a plurality of protrusions 36 for connecting with the inner wall of the barrel body 2. The gap between the two protrusions 36 is a flushing hole 32. The flushing hole 32 is an elongated strip hole. The tap water coming out of the flushing hole 32 is a fan-shaped water flow with a high flow rate, which can efficiently flush the inner wall of the barrel body 2. Moreover, the barrel body 2 is in the shape of a funnel. The inner cavity of the barrel body 2 gradually decreases from top to bottom. The fan-shaped water flow coming out of the flushing hole 32 can fully flush the entire inner wall of the barrel body 2 from top to bottom to ensure that the flushing is in place.

[0031] like Figure 5 As shown, one end of the water inlet pipe 5 is connected to the outer wall of the barrel body 2, and the barrel body 2 is provided with a water opening 21 opposite to the second water outlet 53. The barrel body 2 is provided with two water openings 21, and the tap water flowing out of the second water outlet 53 is divided into the two water openings 21. The aperture of the water opening 21 is smaller than the aperture of the second water outlet 53, which is conducive to increasing the flow rate of the tap water, thereby facilitating the cleaning of the inner wall of the barrel body 2.

[0032] Specifically, the direct-flush toilet of the present invention is made of stainless steel. The top of the upper annular surface 33 and the bottom of the seat surface 11, the outer edge of the upper annular surface 33 and the top of the barrel body 2, and one end of the water inlet pipe 5 and the outer surface of the barrel body 2 are all welded, and the connection is firm and airtight.

[0033] The sewage pipe 6 includes a U-shaped channel 61 and a third horizontal channel 62 connected to one end of the U-shaped channel 61, and the other end of the U-shaped channel 61 is connected to the barrel 2. When the utility model is not flushing, tap water remains in the U-shaped channel 61 to form a liquid seal to isolate odor.

[0034] The above description is only a preferred embodiment of the present invention, and does not limit the patent scope of the present invention. Any equivalent structural transformation made using the contents of the specification and drawings of the present invention, or directly or indirectly applied in other related technical fields, is also included in the patent protection scope of the present invention.
