Description

Toilet bowl and flushing assembly thereof

Technical Field

Background

The intelligent toilet bowl embodies the pursuit of people on comfortable life and healthy life, and the nano antibacterial toilet bowl, paperless warm water cleaning, automatic flushing, deodorization and the like are all common functions of the intelligent toilet bowl. The cleaning function of the intelligent toilet is usually realized by installing a flushing pipeline in the seat ring of the toilet. One end of the flushing pipeline is connected with the cleaning liquid supply device, the other end of the flushing pipeline is provided with a flushing nozzle, a user can open the flushing main pipeline according to the needs, and the flushing nozzle sprays water to clean the privacy part of the user.

Currently, cleaning assemblies typically employ a telescoping nozzle design, i.e., the nozzle is telescopically coupled to the flush line. During the flushing operation, the nozzle is controlled to extend from the seat ring to a set position, and then the spraying operation is performed. The nozzle is retracted into the seat ring in the non-working state and is shielded by the baffle plate, so that the pollution of external dirt is avoided. In the existing cleaning assembly, the extension or retraction of the nozzle is driven by water pressure, namely, the nozzle is pushed to extend by cleaning liquid with certain pressure in a flushing pipeline; after stopping the water supply, the nozzle is retracted under the action of the reset member. The water pressure is too high, so that the spraying pressure is high, and the flushing comfort is poor; while a smaller water pressure does not ensure reliable nozzle extension. Based on this, the present application is presented.
