[0002] The Chinese utility model patent with application number 202221574739.X discloses a sealed toilet flushing device with electrically controlled water inlet, in which a submersible pump is installed in the water tank. The submersible pump is connected to the water outlet of the water tank through a connecting pipe to form an outlet waterway in the water tank, and the submersible pump pumps the water out of the water tank through the outlet waterway. This toilet flushing device does not affect the operation of the flushing device and reduces the probability of seal failure of the external connection of the water pump. In addition, in order to avoid the sewage in the toilet being sucked back into the water tank when negative pressure is generated on the outlet waterway, this toilet flushing device is provided with a one-way valve on the outlet waterway to prevent the water in the water tank from being contaminated and moldy. This method can certainly have an anti-siphon effect, but it is achieved by using a one-way valve, which not only increases the material cost of the one-way valve, but also increases the assembly process of the one-way valve, which ultimately increases the product cost.

[0033] See also Figure 1-Figure 10As shown, a water tank device of the utility model comprises a water tank 1, at least one submersible pump 2 and a water inlet valve 3, wherein the water inlet valve 3 and the submersible pump 2 are respectively arranged in the water tank 1, and the output end of the submersible pump 2 is connected to a water delivery pipeline, so that the water drawn from the water tank 1 by the submersible pump 2 is output through the water delivery pipeline. An anti-siphon hole 53 is arranged on the water delivery pipeline, and the anti-siphon hole 53 is located above the working water level of the water tank 1, and the anti-siphon hole 53 is arranged downward, and the anti-siphon hole 53 is a small hole. When the submersible pump 2 pumps water, a small part of the water flows to the anti-siphon hole 53 and flows back into the water tank 1. The anti-siphon hole 53 is arranged downward, which can promote a part of the water flowing out of the anti-siphon hole 53 to flow directly downward back into the water tank 1, reduce the splashing of this part of the water to the surrounding, and there is no need to set an interception baffle, etc., so that the overall structure is simpler. The anti-siphon hole 53 is set as a small hole, so that the water outlet area of ​​the anti-siphon hole 53 is smaller, thereby reducing the water outlet of the anti-siphon hole 53 and ensuring that most of the water pumped out by the submersible pump 2 is used for flushing.

[0035] like Figure 2 , Figure 3 As shown, the anti-siphon hole 53 is provided on the adapter 5, specifically on the side wall of the first pipe section 51 of the adapter 5, and exposed outside the first water pipe 4. The first pipe section 51 of the adapter 5 is inserted into the other end of the first water pipe 4, and squeezes the other end of the first water pipe 4 outward, so that the two are in an interference fit. A limit block 55 is provided on the adapter 5, and the limit block 55 holds the other end of the first water pipe 4 tightly, so that the other end of the first water pipe 4 is more reliably connected to the first pipe section 51 of the adapter.

[0036] In this embodiment, a mounting opening 11 is provided on the top of the side wall of the water tank 1, and the second pipe section 52 of the adapter 5 passes through the mounting opening 11 and is connected to one end of the second water pipe 6. Figure 5 As shown, the second pipe section 52 of the adapter 5 is inserted into one end of the second water pipe 6, and the one end of the second water pipe 6 is pressed outward, so that the one end of the second water pipe 6 is interference-fitted with the installation opening 11. In this way, the second pipe section 52 of the adapter 5 is more reliably connected to the one end of the second water pipe 6.

[0037] The anti-siphon hole 53 on the adapter 5 is close to the mounting opening 11 at the top of the water tank 1. The adapter 5 is provided with a water retaining portion 54 located in the water tank 1 between the anti-siphon hole 53 and the mounting opening 11. The water retaining portion 54 extends downward.
