[0002] Traditional toilets typically have a tall water tank at the back for flushing; the taller the tank, the stronger the flush. In current technology, to make the toilet more aesthetically pleasing, the water tank is usually hidden within the ceramic body of the toilet. While concealed tanks are more attractive, their insufficient height usually results in a weaker flush.

[0003] Chinese utility model patent CN221567365U discloses an integrated flushing valve with auxiliary flushing function, which increases the flushing force of the toilet by setting up an auxiliary flushing pump and auxiliary flushing water pipeline. However, during use, it was found that this integrated flushing valve with auxiliary flushing function has a problem of unstable drainage. Utility Model Content

[0024] The present invention will be further described below with reference to the accompanying drawings and specific embodiments.

[0025] like Figures 1-6 As shown, this utility model discloses a drainage base, which includes a drainage base body 1, a flushing bend 2, and a flow-blocking member 3. The drainage base body 1 has a flushing inlet 12 on the side wall of its drainage outlet 11. The flushing bend 2 is located inside the drainage outlet 11, with one end connected to the flushing inlet 12 and the other end bent along the drainage direction of the drainage outlet 11. The flow-blocking member 3 is located between the inner arc side of the flushing bend 2 and the side wall of the drainage outlet 11.

[0026] In existing flushing-assisted drain valves, due to the presence of the flushing-assisted bend 2 within the drain base, air can easily accumulate in the space between the inner arc side of the flushing-assisted bend 2 and the side wall of the drain outlet 11 when water flows into the drain base from the drain inlet 13 and out from the drain outlet 11, forming an air blockage. Water can randomly enter or bypass this air blockage-prone area, causing water flow fluctuations and unstable water output. This invention addresses this air blockage-prone area by installing a flow-blocking component 3, which prevents water from entering this area when flowing through the flushing-assisted bend 2. Furthermore, the flow-blocking component 3 guides the water flow axially along the drain outlet 11, thereby reducing water flow fluctuations and improving drainage stability.

[0027] In some embodiments of this utility model, the flushing bend 2 can be integrally formed with the drainage base body 1 or detachably connected. For example, in this embodiment, one end of the flushing bend 2 is inserted into the flushing port 12.

[0028] In some embodiments of this utility model, the flow-blocking member 3 can be selectively connected to the flushing bend 2, or to the drain outlet 11, or both. The connection method can be a fixed connection, such as integral molding, welding, or bonding, or a detachable connection, such as a detachable connection via a snap-fit ​​structure or a detachable connection to the flushing bend 2 via a clamp. To enhance the stability of the connection between the flow-blocking member 3 and the flushing bend 2, reinforcing ribs can be provided between the flow-blocking member 3 and the flushing bend 2.

[0029] In some embodiments of this utility model, the flow-blocking member 3 can be a solid structure or a hollow structure. For example... Figure 6 As shown, in this embodiment, the flow deflector 3 includes two flow deflector plates 31 integrally formed on the flow aid bend 2. The two flow deflector plates 31 are distributed radially along the flow aid bend 2, and there is a gap between them.

[0030] To minimize air entrapment, it is preferable that the bottom surface of the baffle 3 is lower than the toilet's sealing surface. In other embodiments of this invention, the bottom surface of the baffle 3 may also be higher than the toilet's sealing surface, but the distance above the sealing surface should be less than or equal to 10 mm.

[0031] In some embodiments of this utility model, the flushing bend 2 is a Venturi tube with a gradually decreasing diameter. The Venturi tube can increase the flow velocity of the water, thereby improving the flushing effect. The flushing bend 2 can be made into an L-shape, S-shape, U-shape, etc., as needed, so that the water flow sprayed from the flushing bend 2 is consistent with the flushing direction of the toilet. As in this embodiment, the flushing bend 2 is S-shaped, with one end connected to the flushing port 12 and the other end bent out from the drain outlet 11 to be consistent with the flushing direction of the toilet.

[0032] In some embodiments of this utility model, the structure of the drain base body 1 is the same as that of the drain base in the integrated drain valve with flushing aid published in CN221567365U. Combined with Figure 1 In this embodiment, the upper end of the drain base body 1 is a drain inlet 13, and the lower end is a drain outlet 11. The side wall of the drain inlet 13 is provided with a plurality of side inlets 16. The upper outer edge of the drain inlet 13 is provided with locking platforms 14 on opposite sides, which are used to engage with the locking claws on opposite sides of the drain valve 6 housing. The outer side wall of the drain outlet 11 is provided with external threads 15 for connecting to the toilet.

[0033] This utility model also discloses a drain valve 6, which adopts the drain base of this utility model, thereby improving its drainage stability. In some embodiments of this utility model, except for the drain base, the structure of the drain valve 6 is the same as that of the integrated drain valve with flushing aid disclosed in CN221567365U.

[0034] Combination Figure 7 The present invention also discloses a toilet, including: a toilet body 4, and an inlet valve 5 and a drain valve 6 installed in the water storage tank of the toilet body 4, wherein the drain valve 6 adopts the drain valve 6 of the present invention, so that the drainage is more stable.

[0035] Although the present invention has been specifically shown and described in conjunction with preferred embodiments, those skilled in the art should understand that various changes in form and detail to the present invention without departing from the spirit and scope of the present invention as defined in the appended claims are within the scope of protection of the present invention.
