Flushing system of low-water-tank closestool

Abstract

The invention discloses a flushing system of a low-water-tank closestool. The flushing system includes a brush ring pipeline which is used for supplying water to a closestool brush ring, a main flushing pipeline which is used for supplying water to an injection hole in the bottom of a closestool bowl, and an auxiliary flushing pipeline. The water outlet end of the auxiliary flushing pipeline is communicated with the injection hole in the bottom of the closestool bowl, and the water inlet end of the auxiliary flushing pipeline is connected with an external water source through an electromagnetic valve. The water outlet flow velocity and flow of the injection hole can be increased, so that siphon formation of a siphon pipeline of the closestool is accelerated, the siphon effect is better, and the cleaning effect of the closestool is good.

Description

technical field [0001] The invention relates to the field of toilets, in particular to a flushing system of a low water tank toilet. Background technique [0002] Existing low-tank toilets usually have the water tank located at the rear of the toilet slightly lower than the seat of the toilet. When the position of the water tank sinks to the bottom of the water tank and is lower than the upper edge of the brush ring, it is obviously impossible to use the traditional gravity drainage method to supply water to the toilet brush ring; the solution in the prior art is a negative pressure ejector using the principle of negative pressure , the water in the water tank is sucked into the toilet brush ring with a higher level by means of the tap water inlet pressure through a negative pressure ejector (such as Chinese patents CN207660054U, CN207660055U, CN204590209U), or the toilet brush ring is directly connected to the outside through a valve. Water connection. But existing low wa...

When the position of the water tank sinks to the bottom of the water tank and is lower than the upper edge of the brush ring, it is obviously impossible to use the traditional gravity drainage method to supply water to the toilet brush ring; the solution in the prior art is a negative pressure ejector using the principle of negative pressure , the water in the water tank is sucked into the toilet brush ring with a higher level by means of the tap water inlet pressure through a negative pressure ejector (such as Chinese patents CN207660054U, CN207660055U, CN204590209U), or the toilet brush ring is directly connected to the outside through a valve. water connection

But the existing low water tank toilet also has a problem, that is, the position of the water tank is low, which will cause the water outlet speed of the spray hole of the toilet to be slow, so that the siphon pipe of the toilet cannot form a siphon quickly, which affects the cleaning effect of the toilet
