[0030] The present invention will be further described below with reference to the accompanying drawings and specific embodiments.

[0031] Example 1

[0032] like Figure 1 and Figure 2As shown, this embodiment discloses a drain base 1 with an exhaust channel, which includes a drain base body. An exhaust port 111 is provided on the side wall of the drain outlet 11 of the drain base body. An exhaust pipe 13 extends upward from the side wall of the drain outlet 11 outside the drain base body. The exhaust pipe 13 has an exhaust channel 133 communicating with the exhaust port 111. In this embodiment, by providing an exhaust pipe 13 communicating with the drain outlet 11 on the outside of the drain base body, air bubbles in the water flow passing through the drain base 1 can be discharged from the exhaust pipe 13, thereby reducing air bubble retention in the water flow and preventing large air bubbles from appearing at the toilet nozzle during flushing.

[0033] In this embodiment, the upper end of the drain base body is a drain inlet 12, and the lower end is a drain outlet 11. The side wall of the drain inlet 12 has several side inlets 121. On opposite sides of the upper outer edge of the drain inlet 12, there are locking platforms 122 for engaging with the locking claws on opposite sides of the housing 2 of the drain valve 9. The outer wall of the drain outlet 11 is provided with external threads 113 for connection to the toilet. The assembly relationship between the drain base 1 and the housing 2 can be referred to the integrated flushing-assisted drain valve with announcement number CN221567365U.

[0034] Example 2

[0035] like Figure 3 and Figure 4 As shown, this embodiment adds a water supply pipe 14 and a toilet seat condensate collection pipe 15 to the first embodiment.

[0036] One end of the water supply pipe 14 is connected to the side wall of the exhaust pipe 13 and communicates with the exhaust channel 133. The other end is connected to the toilet's inlet valve via a water supply conduit, enabling the toilet to supply water. One end of the toilet seat condensate collection pipe 15 is connected to the side wall of the exhaust pipe 13 and communicates with the exhaust channel 133. The other end is connected to the toilet seat via a condensate conduit, enabling the collection and discharge of condensate from the toilet seat. Both the water supply pipe 14 and the toilet seat condensate collection pipe 15 are connected to the exhaust pipe 13, allowing the supply water and condensate to be vented as they pass through the exhaust pipe 13, thus reducing air bubbles entering the drain outlet 11.

[0037] In this embodiment, the exhaust pipe 13 includes a first pipe section 131 extending horizontally outward from the side wall of the drain outlet 11, and a second pipe section 132 extending upward from the end of the first pipe section 131 away from the drain outlet 11. The water supply pipe 14 and the toilet seat condensate collection pipe 15 are connected to the second pipe section 132.

[0038] Example 3

[0039] This embodiment adds an auxiliary bending pipe 16 to the existing embodiment one or embodiment two.

[0040] Combination Figure 5 and Figure 6 The drain outlet 11 of the drain base body has a flushing aid 112 on its side wall. A flushing aid bend 16 is located inside the drain outlet 11. One end of the flushing aid bend 16 is connected to the flushing aid 112, and the other end is bent along the draining direction of the drain outlet 11. The flushing aid bend 16 is a Venturi tube with a gradually decreasing diameter. The Venturi tube can increase the flow velocity of the water and achieve a better flushing effect.

[0041] Due to the presence of the flushing bend 16 inside the drainage base 1, when water flows into the drainage base 1 from the drainage inlet 12 and out from the drainage outlet 11, air is easily trapped in the space between the inner arc side of the flushing bend 16 and the side wall of the drainage outlet 11 below the flushing inlet 112, forming an air blockage. The water flow randomly enters or bypasses this air blockage-prone area, causing water flow fluctuations and resulting in unstable water output.

[0042] To improve the stability of the water output, a baffle 17 can be connected between the flushing bend 16 below the flushing inlet 112 and the drain outlet 11.

[0043] The flow deflector 17 can prevent water from entering the air resistance-prone area when it flows through the flushing bend 16, and the flow deflector 17 can guide the water to flow axially along the drain outlet 11, thereby reducing water flow fluctuations and improving drainage stability.

[0044] Example 4

[0045] Combination Figures 7-10 This embodiment discloses a drain valve 9, which includes: a housing 2, a water pump 3, a drain device 4, and a drain base 1. The water pump 3 and the drain device 4 are installed inside the housing 2, and the drain base 1 is installed below the housing 2. The drain base 1 in this embodiment is the drain base 1 of Embodiment 3. In other embodiments of this utility model, the drain base 1 can also be the drain base 1 of Embodiment 1 or Embodiment 2. The housing 2, water pump 3, and drain device 4 of the drain valve 9 in this embodiment can be the same as the integrated drain valve with flushing aid as disclosed in CN221567365U. The flushing aid port 112 of the drain base 1 is connected to the outlet of the water pump 3, and the drain device 4 is used to open and close the drain outlet 11 of the drain base body. The exhaust pipe 13 of the drain base 1 is connected to an exhaust conduit 5, the air inlet 51 of the exhaust conduit 5 is connected to the exhaust channel 133, and the exhaust end 52 of the exhaust conduit 5 extends out of the water surface of the water tank. In some other embodiments of this utility model, the exhaust conduit 5 is not provided, but the exhaust pipe 13 is provided to extend upward to extend out of the water surface of the water tank.

[0046] For ease of assembly, the exhaust duct 5 in this embodiment is housed within the housing 2. The bottom of the housing 2 has a raised hole 21 protruding from its surface, and hooks 22 are provided on opposite sides of the raised hole 21. A protruding ring 53 is provided between the inlet end 51 and the exhaust end 52 of the exhaust duct 5. The inlet end 51 of the exhaust duct 5 is inserted into the raised hole 21 until the protruding ring 53 abuts against the end face of the raised hole 21. The hooks 22 engage with the protruding ring 53 to press the protruding ring 53 firmly onto the raised hole 21. The inlet end 51 of the exhaust duct 5 extends downwards through the housing 2 and is fitted with a sealing ring 6. The exhaust pipe 13 is fitted onto the inlet end 51 of the exhaust duct 5, and the exhaust pipe 13 and the exhaust duct 5 are sealed together by the sealing ring 6. When assembling the drain valve 9, first pre-assemble the exhaust pipe 5 and the housing 2 into a whole, and then assemble the drain base 1. During assembly, align the exhaust pipe 13 with the air inlet end 51 of the exhaust pipe 5, and then snap the drain base 1 into the housing 2. Insert the air inlet end 51 of the exhaust pipe 5 into the exhaust pipe 13 to complete the assembly.

[0047] Due to the limited internal space of the housing 2, the exhaust end 52 of the exhaust duct 5 may be set at an angle. In order to install it in place in one go and avoid interference between components, a positioning groove 531 can be set on the convex ring 53, and a positioning block 211 that is inserted and matched with the positioning groove 531 is provided on the raised hole 21.

[0048] Since the exhaust duct 5 is located inside the housing 2, if the end face of the exhaust end 52 of the exhaust duct 5 touches the top surface of the housing 2, it may block the exhaust duct 5 and cause poor exhaust. Therefore, a number of grooves 521 penetrating the exhaust duct 5 can be provided on the end face of the exhaust end 52 of the exhaust duct 5 so that the gas can be discharged from the grooves 521 when such a situation occurs.
