Description

Technical Field

[0001] The utility model relates to the technical field of negative pressure water seals, in particular to a PCV negative pressure water seal structure which is convenient for clearing blockages. Background Art

[0002] Water seal refers to a water column of a certain height in the device to prevent the gas in the drainage pipe system from entering the room. In the building drainage pipe, the water seal refers to a water column of a certain height installed under the drainage outlet of the sanitary ware to resist the pressure difference change in the drainage pipe and prevent the gas in the drainage pipe system from entering the room. It is usually achieved by a water trap. A water seal is a separation method that uses water to separate the two parts of gas to be isolated.

[0003] The disclosure discloses a toilet and a negative pressure siphon flushing structure thereof with the publication number CN206529863U. The negative pressure siphon flushing structure includes a toilet body, a water storage tank, a drain valve and a negative pressure generating component. When working, the drain valve is opened, and all the water in the water storage tank passes through the flushing pipe to flush the inner wall of the toilet bowl, thereby ensuring the amount of water and flushing force of the flushing water. When the flushing water approaches the water seal surface in the toilet bowl, the negative pressure generating component generates negative pressure in the negative pressure generating section of the siphon pipe, and the negative pressure absorbs the water in the toilet bowl. The water passes through the negative pressure generating section from the water seal section and is discharged from the flushing section. The negative pressure generated by the negative pressure generating component and the siphon force generated by the flushing water after passing through the siphon pipe act together on the water in the toilet bowl, siphoning away the water in the toilet bowl. The two forces act to create a greater siphon force, and the water consumption can be smaller, which is beneficial to saving water resources.

[0004] Deficiencies in the prior art: The existing negative pressure water seal structure is usually set as an integrated structure. When a blockage occurs inside the negative pressure water seal structure, the blockage inside the negative pressure water seal structure can only be cleaned by completely disassembling the entire negative pressure water seal structure. The negative pressure water seal structure cannot be divided into multiple parts, and thus the blockage deep inside the negative pressure water seal structure cannot be quickly cleaned, which will affect the working state of the negative pressure water seal structure.
