Water outlet box of pressure type flushing system and toilet bowl using same

Abstract

The present invention discloses a water outlet box of a pressure type flushing system and a toilet bowl using the water outlet box. The water outlet box comprises a water outlet box main body and a first one-way valve assembly; the water outlet box main body is provided with a water-passing chamber, a water inlet, at least one water outlet, and an air vent; the water inlet, the water outlet and the air vent all communicate with the water-passing chamber; the first one-way valve assembly is arranged opposite to the water inlet to open or block the water inlet; at the end of flushing by using the pressure flushing system, the first one-way valve assembly blocks the water inlet; the air vent is arranged at the top of the water-passing chamber and is connected with the atmosphere; and the water outlet box main body is provided with a plurality of water inlet pipes that communicate with the functional devices of the pressure type flushing system. According to the technical scheme of the present invention, pressure release or water discharge of the functional devices of the pressure type flushing system can be realized, the internal pressure balance can be ensured, and the connection structure of the toilet bowl can be simplified; and the function of anti-siphon is provided to ensure the internal cleanness of the pressure type flushing system.

Description

technical field [0001] The invention relates to the field of sanitary ware, in particular to a water outlet box of a pressure flushing system and a toilet using the water outlet box. Background technique [0002] A toilet (toilet) generally includes two parts, a seat body and a water tank, wherein a flushing system is installed in the water tank to flush the toilet. The commonly used flushing system is to use the principle of gravity, that is, to convert the gravitational potential energy of water into the kinetic energy of water to flush the toilet. However, this flushing system requires a large amount of water, and the water tank must be raised to a certain height, otherwise the flushing effect cannot be achieved. [0003] At present, there is a pressure flushing system on the market. By setting up a pressure water tank, the pressure energy accumulated by the compressed gas in the pressure water tank is used to make the water in the pressure water tank produce a strong fl...

AI Technical Summary

Problems solved by technology

The functional devices of the above-mentioned pressure flushing system (such as drain valve, drain valve control component, solenoid valve, pressure stabilizing valve, etc.) realize the corresponding functions through drainage, and the discharged water cannot flow into the ceramics where the pressure flushing system is installed. Otherwise, the water flow will accumulate in the ceramic, which will affect the use effect of the functional device. Therefore, the water must be discharged to the flushing pipe of the toilet, which will lead to a complicated connection structure of the existing flushing pipe of the toilet.
